本发明涉及物理模型试验制模辅助装置及方法，特别涉及一种用于微型传感器精确定位及快速埋设的装置和方法。The invention relates to an auxiliary device and method for making molds for physical model tests, in particular to a device and method for precise positioning and rapid embedding of micro sensors.
背景技术Background technique
在岩土工程物理模型试验中，土体模型内部土压力及孔隙水压力的测量是研究土体受力状态、结构物力学性能的重要手段。如何能够快速、准确地按照设计位置将传感器埋入土体模型中将直接关系到试验结果的准确性，而且不同的试验对传感器的埋设角度和埋设位置要求不同。传统的传感器埋设方法是：事先准备铝管，根据具体埋设深度及埋设角度要求，在铝管粘贴埋设标记点，再将铝圆管一端开一长条状缺口，将传感器放入其中，引线从缺口处引出；准备相应角度的泡沫块，斜坡中间开半圆形长槽，用于铝管的辅助定位，然后开始埋设工作。In geotechnical engineering physical model tests, the measurement of soil pressure and pore water pressure inside the soil model is an important means to study the stress state of soil and the mechanical properties of structures. How to quickly and accurately embed the sensor in the soil model according to the designed position will directly affect the accuracy of the test results, and different tests have different requirements for the embedment angle and embedment position of the sensor. The traditional sensor embedding method is: prepare the aluminum tube in advance, paste and embed marking points on the aluminum tube according to the specific embedding depth and embedding angle requirements, and then open a long strip-shaped gap at one end of the aluminum round tube, put the sensor into it, and the lead wire from Lead out from the gap; prepare foam blocks with corresponding angles, and open a semicircular long slot in the middle of the slope for auxiliary positioning of aluminum tubes, and then start the embedding work.
传统的埋设方法缺点主要有以下几个方面：The disadvantages of traditional embedding methods mainly include the following aspects:
(1)在埋设过程中，输送铝管的前部易对传感器壳体和引线造成伤害，导致传感器损坏；(1) During the embedding process, the front part of the conveying aluminum pipe is easy to cause damage to the sensor housing and lead wires, resulting in damage to the sensor;
(2)埋设角度主要依靠事先准备的泡沫块来辅助确定，泡沫块的加工及制作困难，且角度不可调节，埋设过程角度极易发生偏转，造成角度定位不准；(2) The embedding angle is mainly determined by the pre-prepared foam block. The processing and production of the foam block is difficult, and the angle cannot be adjusted. The angle is easily deflected during the embedding process, resulting in inaccurate angle positioning;
(3)埋设深度靠铝管上粘贴的标记来控制，粘贴的标记位置不够灵活，造成埋设深度不准确，且在埋设过程中容易出现脱落的现象。(3) The embedding depth is controlled by the mark pasted on the aluminum tube. The position of the pasted mark is not flexible enough, resulting in inaccurate embedding depth and prone to falling off during the embedding process.

具体实施方式Detailed ways
为能进一步了解本发明的发明内容、特点及功效，兹例举以下实施例，并配合附图详细说明如下：In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
请参阅图1～图6，一种用于微型传感器精确定位及快速埋设的装置，包括定位架1、角度定位轨道2、深度定位轨道3和输送棒4。Please refer to FIGS. 1 to 6 , a device for precise positioning and rapid embedding of micro sensors, including a positioning frame 1 , an angle positioning track 2 , a depth positioning track 3 and a delivery rod 4 .

An angle positioning groove 1-1 is provided on the positioning support base plate with a horizontal positioning scale 1-3 corresponding to the entry point of the angle positioning groove 1-1.
所述角度定位轨道2设有滑槽2-3，所述角度定位轨道2的一个侧面与所述半圆形角度定位板相邻，并设有与所述角度定位槽1-1插接的定位凸块2-2，所述角度定位轨道2的背面下端设有与所述销轴1-2转动连接的销孔2-1。The angle positioning track 2 is provided with a chute 2-3, and one side of the angle positioning track 2 is adjacent to the semicircular angle positioning plate, and is provided with a slot that is inserted into the angle positioning groove 1-1. The positioning projection 2-2, the lower end of the back of the angular positioning track 2 is provided with a pin hole 2-1 that is rotatably connected with the pin shaft 1-2.
所述深度定位轨道3插装在所述角度定位轨道2的滑槽内，在所述深度定位轨道3内设有与传感器尺寸吻合的滑槽3-2，在所述深度定位轨道2的外侧设有尺寸刻度3-1。The depth positioning track 3 is inserted in the chute of the angle positioning track 2, a chute 3-2 matching the size of the sensor is provided in the depth positioning track 3, and on the outside of the depth positioning track 2 There is a size scale 3-1.
所述输送棒4插装在所述深度定位轨道3的滑槽内，设有推杆，在所述推杆的头端设有与传感器适配的顶推部4-1，在所述推杆的尾部设有埋设结束刻线4-2，当所述输送棒4将传感器5推出深度定位轨道的滑槽3-2时，埋设结束刻线4-2进入深度定位轨道的滑槽3-2。也可以说，当埋设结束刻线4-2进入深度定位轨道的滑槽3-2时，表明传感器5已经脱离深度定位轨道3而埋入土中。所述输送棒4的长度应大于深度定位轨道3的长度。The conveying rod 4 is inserted in the chute of the depth positioning track 3, and a push rod is provided, and a push part 4-1 adapted to the sensor is arranged at the head end of the push rod. The end of the rod is provided with a buried end score line 4-2. When the delivery rod 4 pushes the sensor 5 out of the chute 3-2 of the depth positioning track, the end of the burying score line 4-2 enters the chute 3-2 of the depth positioning track. 2. It can also be said that when the embedding end score line 4-2 enters the chute 3-2 of the depth positioning track, it shows that the sensor 5 has broken away from the depth positioning track 3 and is buried in the soil. The length of the conveying rod 4 should be greater than the length of the depth positioning track 3 .
所述定位架的矩形定位支撑底板上的与所述角度定位槽对应的入土起始点横向定位刻度1-3用于准确定位入土起始点。因为深度定位轨道3和传感器5的推送轨迹偏离半圆形角度定位板的圆心，导致入土起始点的位置不易确定。为了准确确定入土起始点的位置，本发明在所述定位架1的矩形定位支撑底板上标出了与所述角度定位槽对应的入土起始点横向定位刻度1-3用于准确定位入土起始点。入土起始点横向定位刻度1-3的确定方法：请参阅图7和图8，传感器入土起始点的位置位于矩形定位支撑底板1的底部，无法准确确定，并且当角度定位轨道2绕销轴1-2时，传感器入土起始点与销轴1-2的距离发生变化，如图所示，角度定位轨道处于90°时，传感器入土起始点与销轴1-2的距离为2.4mm，角度定位轨道处于30°时，传感器入土起始点与销轴1-2的距离为7mm。因此需要针对不同的埋设角度提前将传感器入土起始点的横向位置竖直投影至矩形定位支撑底板1的上表面，并将其横向位置刻于矩形定位支撑底板1上，也就是入土起始点横向定位刻度1-3。The horizontal positioning scale 1-3 of the starting point of the soil entry corresponding to the angular positioning groove on the rectangular positioning support base plate of the positioning frame is used to accurately locate the starting point of the soil entry. Because the pushing trajectory of the depth positioning track 3 and the sensor 5 deviates from the center of circle of the semicircular angle positioning plate, the position of the starting point of entering the soil is difficult to determine. In order to accurately determine the position of the starting point of digging into the soil, the present invention marks the starting point of digging into the soil corresponding to the angle positioning groove on the rectangular positioning support base plate of the positioning frame 1. . The method of determining the horizontal positioning scale 1-3 of the starting point of the soil entry: Please refer to Figure 7 and Figure 8. The position of the sensor’s soil entry starting point is located at the bottom of the rectangular positioning support base plate 1, which cannot be accurately determined. -2, the distance between the starting point of the sensor entering the soil and the pin shaft 1-2 changes, as shown in the figure, when the angle positioning track is at 90°, the distance between the starting point of the sensor entering the soil and the pin shaft 1-2 is 2.4mm, and the angle positioning When the track is at 30°, the distance between the starting point of the sensor entering the soil and the pin axis 1-2 is 7mm. Therefore, it is necessary to vertically project the lateral position of the starting point of the sensor into the soil to the upper surface of the rectangular positioning support base plate 1 in advance for different embedding angles, and engrave its lateral position on the rectangular positioning support base plate 1, that is, the lateral positioning of the starting point of the soil entry Scale 1-3.
在本实施例中，所述角度定位轨道2的滑槽和所述深度定位轨道3的滑槽横截面均采用凸字形，便于槽内部件稳定滑动，有效防止槽内部件脱出。所述输送棒的顶推部4-1采用开口结构，便于保护传感器，可避免传感器受到损伤。为了更加方便操作，在所述推杆的尾部还可设有埋设起始刻线(图中未示出)。所有所述角度定位槽1-1沿周向均匀布置，间隔为15°。In this embodiment, the chute of the angle positioning track 2 and the chute of the depth positioning track 3 are convex in cross-section, which facilitates the stable sliding of the components in the trough and effectively prevents the components in the trough from falling out. The pushing part 4-1 of the conveying rod adopts an open structure, which is convenient for protecting the sensor and avoiding the sensor from being damaged. In order to be more convenient to operate, an embedded starting score line (not shown in the figure) may also be provided at the tail of the push rod. All the angle positioning grooves 1-1 are evenly arranged along the circumferential direction with an interval of 15°.

二)在土体模型的土面上以预设入土起始点为中心画十字交叉的横向线和纵向线，使定位支撑底板上与传感器设计埋设角度对应的横向定位刻度与纵向线重合，然后沿纵向调节定位支撑底板的位置，使预设入土起始点进入埋设入口并与角度定位轨道2的宽度中点横向对齐，完成定位支撑底板的定位，也完成了定位架的定位。2) On the soil surface of the soil model, draw a crossed horizontal line and a vertical line centered on the preset starting point of the soil, so that the horizontal positioning scale corresponding to the sensor design embedding angle on the positioning support base plate coincides with the vertical line, and then along the The position of the positioning support base plate is adjusted longitudinally, so that the preset starting point of soil entry enters the buried entrance and is horizontally aligned with the width midpoint of the angle positioning track 2, and the positioning of the positioning support base plate is completed, and the positioning of the positioning frame is also completed.
