降雨感应电磁继电器Rain sensing electromagnetic relay

技术领域technical field

本发明涉及传感器领域，具体的说是一种降雨感应电磁继电器。The invention relates to the field of sensors, in particular to a rain-sensing electromagnetic relay.

技术背景technical background

降雨是自然界普遍存在的气象现象。对于一些需要防雨的设施及物品而言，当降雨发生时能及时遮盖防雨装置，可以减少降雨带来的不便和损失。因此自动感应到降雨的发生，对于防雨具有重要意义。Rainfall is a common meteorological phenomenon in nature. For some facilities and articles that need to be protected from rain, the rainproof device can be covered in time when the rain occurs, which can reduce the inconvenience and loss caused by the rain. Therefore, automatic sensing of the occurrence of rainfall is of great significance for rain protection.

传统的雨量传感器是用来计量雨量大小的，只有当雨量达到一定程度时，传统的雨量传感器才能感应到降雨的发生，因此造成对降雨感应的迟钝。中国专利CN201247214公开了一种降水感知器，采用电路板表面的水膜作为感知降雨发生的传感器，由于印刷电路板自身的局限性，会因表面露水、霜冻等造成降水误报，在野外使用时，由于电路板暴露，鸟类粪便也会造成降水误报。德国生产了一种光电降雨传感器，利用雨滴通过红外发射-接收装置时对红外光的遮挡感应到降雨的发生，该降雨传感器会对其他颗粒物通过红外区域时产生降雨误报，也会因“绵绵细雨”的雨滴过小而不报。The traditional rain sensor is used to measure the amount of rainfall. Only when the rainfall reaches a certain level, the traditional rain sensor can sense the occurrence of rainfall, thus causing a slow response to rainfall. Chinese patent CN201247214 discloses a precipitation sensor, which uses the water film on the surface of the circuit board as a sensor for sensing the occurrence of rainfall. Due to the limitations of the printed circuit board itself, it will cause false precipitation due to surface dew, frost, etc., when used in the field , due to exposed circuit boards, bird droppings can also cause false precipitation reports. Germany produced a photoelectric rainfall sensor, which uses the shielding of infrared light by raindrops when passing through the infrared transmitter-receiver to sense the occurrence of rainfall. "Drizzle" raindrops are too small to be reported.

为了解决现有技术中存在的问题，本发明提供一种造价低廉，感应准确、使用方便的降雨感应电磁继电器。In order to solve the problems existing in the prior art, the invention provides a rain-sensing electromagnetic relay with low cost, accurate induction and convenient use.

为了实现这一目的，本发明提供如下解决方案：In order to achieve this goal, the present invention provides following solutions:

一种降雨感应电磁继电器，其特征在于包括集雨杯12、防露罩11、电极31和32、杠杆5、直流电池2、电磁铁4。A rain-sensing electromagnetic relay is characterized by comprising a rain-collectingcup 12, a dew-proof cover 11,electrodes 31 and 32, alever 5, aDC battery 2, and anelectromagnet 4.

Twoelectrodes 31 and 32 are installed under the hole at the bottom of therain collecting cup 12. Theelectrode 32 is connected to an electrode of theDC battery 2 through awire 71 , theelectrode 31 is connected with theelectromagnet 4 through thewire 72, and theelectromagnet 4 is connected with the other electrode of theDC battery 2 through thewire 73 to form a loop;

Next, make theelectromagnet 4 generate magnetism, attract thelever 5, and connect theelectrodes 61 and 62.

当降雨停止时，从集雨杯12下端的孔流出的水停止流出，电极31、32之间的水膜在重力作用下滴落，并在蒸发作用下自然干燥，造成电极31、32断开连接，电磁铁4停止工作，磁性消失，杠杆5在重力作用下自然下垂，使杠杆5脱离电极62，电极61、62断开。When the rain stops, the water flowing from the hole at the lower end of therain collecting cup 12 stops flowing out, and the water film between theelectrodes 31, 32 drops under the action of gravity, and dries naturally under the action of evaporation, causing theelectrodes 31, 32 to be disconnected Connect, theelectromagnet 4 stops working, the magnetism disappears, thelever 5 naturally sags under the action of gravity, thelever 5 is separated from theelectrode 62, and theelectrodes 61, 62 are disconnected.

具体实施方式Detailed ways

下面结合附图详细说明本发明的技术方案：The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

本发明提供一种降雨感应电磁继电器，由集雨杯12、电极31、32、直流电池2、电磁铁4等构成。如图1所示。The present invention provides a rainfall induction electromagnetic relay, which is composed of arain collecting cup 12,electrodes 31, 32, aDC battery 2, anelectromagnet 4 and the like. As shown in Figure 1.

集雨杯12呈圆锥形，底部有孔，可以保证雨水从孔中泄漏，在集雨杯12底部的孔下安装有两个电极31、32，电极31、32由不锈钢等金属片制成，相互重叠并行排列，重叠部分长度为1～10cm，重叠部分间距为0.5～5mm，电极31、32金属片的宽度为0.1～5cm。电极32通过导线71与直流电池2的一个电极连接，电极31通过导线72与电磁铁4连接，电磁铁4通过导线73与直流电池2的另一个电极连接，形成回路。在集雨杯12与电极31、32外装有防露罩11，防止电极31、32上凝露。防露罩11为金属或塑料材质，上表面开圆形口，开口大小与集雨杯12的口一致，集雨杯12刚好安装在开口处。防露罩11的地面为镂空结构，可以保证雨水顺畅排出。在电磁铁4下部安装有铁质杠杆5，杠杆5的支点和另一端分别连接电极61、62。杠杆5的支点与电磁铁4的距离大于支点到另一端的距离，保证电磁铁4没有磁性时，杠杆5可以在重力作用下自然下垂，造成电极62与杠杆5脱离。The rain-collectingcup 12 is conical and has a hole at the bottom to ensure that rainwater leaks from the hole. Twoelectrodes 31 and 32 are installed under the hole at the bottom of the rain-collectingcup 12. Theelectrodes 31 and 32 are made of metal sheets such as stainless steel. They are overlapped and arranged in parallel, the length of the overlapping part is 1-10 cm, the distance between the overlapping parts is 0.5-5 mm, and the width of the metal sheets of theelectrodes 31 and 32 is 0.1-5 cm. Theelectrode 32 is connected to one electrode of theDC battery 2 through awire 71, theelectrode 31 is connected to theelectromagnet 4 through awire 72, and theelectromagnet 4 is connected to the other electrode of theDC battery 2 through awire 73 to form a loop. The rain-collectingcup 12 and theelectrodes 31,32 are equipped with a dew-proof cover 11 to prevent condensation on theelectrodes 31,32. Theanti-dew cover 11 is a metal or plastic material, and the upper surface has a round mouth, and the size of the opening is consistent with the mouth of the rain-collectingcup 12, and the rain-collectingcup 12 is just installed in the opening. The ground of theanti-dew cover 11 is a hollow structure, which can ensure the smooth discharge of rainwater. Aniron lever 5 is installed at the bottom of theelectromagnet 4, and the fulcrum and the other end of thelever 5 are respectively connected toelectrodes 61, 62. The distance between the fulcrum of thelever 5 and theelectromagnet 4 is greater than the distance from the fulcrum to the other end, so that when theelectromagnet 4 has no magnetism, thelever 5 can naturally sag under the action of gravity, causing theelectrode 62 to break away from thelever 5 .

当降雨发生时，雨水落入集雨杯12，从集雨杯12下端的孔流出，流出的雨水滴落在电极31、32之间，造成电极31、32连通，在直流电池2电流的作用下，使电磁铁4产生磁性，吸引杠杆5，使电极61、62连通。When rainfall occurs, rainwater falls into the rain-collectingcup 12, flows out from the hole at the lower end of the rain-collectingcup 12, and the outflowing rainwater drops between theelectrodes 31 and 32, causing theelectrodes 31 and 32 to communicate. Next, make theelectromagnet 4 generate magnetism, attract thelever 5, and connect theelectrodes 61 and 62.

当降雨停止时，从集雨杯12下端的孔流出的水停止流出，电极31、32之间的水膜在重力作用下滴落，并在蒸发作用下自然干燥，造成电极31、32断开连接，电磁铁4停止工作，磁性消失，杠杆5在重力作用下自然下垂，使杠杆5脱离电极62，电极61、62断开。When the rain stops, the water flowing from the hole at the lower end of therain collecting cup 12 stops flowing out, and the water film between theelectrodes 31, 32 drops under the action of gravity, and dries naturally under the action of evaporation, causing theelectrodes 31, 32 to be disconnected Connect, theelectromagnet 4 stops working, the magnetism disappears, thelever 5 naturally sags under the action of gravity, thelever 5 is separated from theelectrode 62, and theelectrodes 61, 62 are disconnected.
