背景技术Background technique
在水利水电开发建设技术领域，过水建筑物的下游消能防冲技术，一直是坝工界极为关注的重点。特别是当过水建筑物处于地质条件相对薄弱的地段，下游消能防冲技术的作用更为凸显。目前，坝工界多采用向消能池内抛石的方法达到消能的目的，然而这种消能方式，存在如下弊端：首先，抛石粒径的选择难以适应连续且不同流量的多种洪水过程的消能；其次，无法及时补充和恢复被水流冲出消能池的抛石；再次，被水流冲走的抛石会加速下游河床的淤积、造成河道变形失稳。为此，亟需设计一个全新的消能技术手段，加速解决坝工消能问题。为此，本发明提供了一个全新的消能技术手段，加速解决坝工消能问题。In the field of water conservancy and hydropower development and construction technology, the downstream energy dissipation and anti-scour technology of water-passing buildings has always been a focus of great concern to the dam industry. Especially when water-passing buildings are located in areas with relatively weak geological conditions, the role of downstream energy dissipation and anti-scour technology is even more prominent. At present, the dam industry mostly uses the method of riprap into the energy dissipation tank to achieve the purpose of energy dissipation. However, this energy dissipation method has the following disadvantages: First, the selection of the riprap particle size is difficult to adapt to multiple floods with continuous and different flows. The energy dissipation process; secondly, the riprap washed out of the energy dissipation pool by the current cannot be replenished and restored in time; thirdly, the riprap washed away by the current will accelerate the sedimentation of the downstream river bed and cause the river channel to deform and become unstable. For this reason, there is an urgent need to design a new energy dissipation technology to speed up the solution to the energy dissipation problem of dam construction. To this end, the present invention provides a brand-new energy dissipation technical means to accelerate the solution of the energy dissipation problem of dam construction.

The two adjacent water retaining overflow walls 3 and the bottom plate 2 of the two adjacent energy dissipation water tanks 8 form an energy dissipation and sand removal chamber 6, the far left A water retaining overflow wall 3 on the side, the left side wall 1 and the bottom plate 2 form an energy dissipation and sand removal chamber 6, and the rightmost water retaining overflow wall 3, the right side wall 1 and the bottom plate 2 form an energy dissipation and sand removal chamber. The sand chamber 6 is provided with a sand discharge gate 5 downstream of the energy dissipating sand chamber 6 .
当水流经由衔接段流至消能除沙段时，由于横向设置的消能分水墙2与水流方向相垂直，所以水流撞击到消能分水墙2上，由此对水流实现了第一次碰撞物体消能；最左侧一块消能分水墙2和左侧侧墙1之间的间隔为供水流进入最左侧一个消能除沙厢6的进水通道，最右侧一块消能分水墙2和右侧侧墙1之间的间隔为供水流进入最右侧一个消能除沙厢6的进水通道，相邻两个消能输水槽8的两块消能分水墙2之间的间隔为供水流进入位于该相邻两个消能输水槽8之间的一个消能除沙厢6的进水通道，水流经由进水通道进入消能除沙厢6中，而由于消能除沙厢6仅在上游有一个进水通道，消能除沙厢6下游、左右两侧均被阻挡，由此水流在消能除沙厢6实现了第一次自我碰撞消能，挡水溢流墙3顶部设有左右贯通的溢流口4，消能除沙厢6内的上层清水经由溢流口4流至消能输水槽8中，水流中携带的泥沙沉淀至消能除沙厢6底部，当消能除沙厢6内沉淀的泥沙达到一定量时，打开排沙闸5排出泥沙；由于每一个消能输水槽8具有左右两个溢流口4，从左右两个溢流口4流入的水流流向相向，由此水流在消能输水槽8内实现了第二次自我碰撞消能，最后水流经由输水闸7流出。水流流经本申请的厢式消能除沙池时实现了三次碰撞消能，消能效果好，无需再通过向池内抛石的方式来进行消能，由此彻底的消除了人为主动向池内抛石消能所带来的下游河床淤积问题，同时有效的改善了过去常规消力池内部的流态特性，使消力池内部的消能效果更好，另外本申请维护成本低、易建造、应用广泛，不仅适用于引水灌溉消能领域，也适用于中小型发电消能领域，特别是对高泥沙含量的季节性河流，具有其他消能方式无法取代的独特作用。When the water flows through the connection section to the energy dissipation and sand removal section, since the energy dissipation water separation wall 2 is arranged horizontally perpendicular to the direction of the water flow, the water flow hits the energy dissipation water separation wall 2, thus achieving the first effect on the water flow. The energy dissipation of the first collision object; the distance between the energy dissipation water separation wall 2 on the far left and the left side wall 1 is the water inlet channel for the water supply flow to enter the energy dissipation and sand removal chamber 6 on the far left. The interval between the water-dividing wall 2 and the right side wall 1 is the water inlet channel for the water supply flow to enter the energy-dissipating and sand-removing chamber 6 on the far right. The interval between the walls 2 is a water inlet channel for the water supply flow to enter an energy dissipation and sand removal chamber 6 located between the two adjacent energy dissipation water channels 8. The water flow enters the energy dissipation and sand removal chamber 6 through the water inlet channel. Since the energy dissipation and sand removal chamber 6 only has a water inlet channel upstream, the downstream and left and right sides of the energy dissipation and sand removal chamber 6 are blocked, so the water flow achieves the first self-collision elimination in the energy dissipation and sand removal chamber 6. Yes, the top of the water retaining overflow wall 3 is provided with an overflow port 4 that connects the left and right sides. The upper clear water in the energy dissipation and sand removal chamber 6 flows through the overflow port 4 to the energy dissipation water tank 8, and the sediment carried in the water flow settles. to the bottom of the energy dissipation and sand removal chamber 6, when the sediment deposited in the energy dissipation and sand removal chamber 6 reaches a certain amount, the sand discharge gate 5 is opened to discharge the sediment; since each energy dissipation water tank 8 has two overflow ports on the left and right 4. The water flow flowing in from the two left and right overflow ports 4 flows in opposite directions, so the water flow realizes the second self-collision and energy dissipation in the energy dissipation tank 8, and finally the water flows out through the water transfer gate 7. When the water flows through the box-type energy dissipation and sand removal tank of this application, it achieves three collisions to dissipate energy, and the energy dissipation effect is good. There is no need to dissipate energy by throwing rocks into the pool, thus completely eliminating the need for people to actively throw stones into the pool. The downstream riverbed sedimentation problem caused by riprap energy dissipation also effectively improves the flow characteristics inside the conventional stilling basin, making the energy dissipation effect inside the stilling basin better. In addition, this application has low maintenance costs and is easy to construct. , widely used, not only in the field of water diversion and irrigation energy dissipation, but also in the field of small and medium-sized power generation and energy dissipation.

根据需求，排沙闸5和输水闸7均可采用现有公知技术，具体的，于本实施例中，底板二上左右均匀间隔设有3块消能分水墙，连接在最左侧一块消能分水墙2上的左侧一块挡水溢流墙3的下游和左侧侧墙1的下游之间设有一个排沙闸5，连接在最左侧一块消能分水墙2上的右侧一块挡水溢流墙3的下游和连接在中间一块消能分水墙2上的左侧一块挡水溢流墙3的下游之间设有一个排沙闸5，连接在中间一块消能分水墙2上的右侧一块挡水溢流墙3的下游和连接在最右侧一块消能分水墙2上的左侧一块挡水溢流墙3的下游之间设有一个排沙闸5，连接在最右侧一块消能分水墙2上的右侧一块挡水溢流墙3的下游和右侧侧墙1下游之间设有一个排沙闸5，连接在每块消能分水墙2上的两块挡水溢流墙3下游之间均设有一个输水闸7，由此形成依次交替分布的4个消能除沙厢6和3个消能输水槽8。According to needs, both the sand discharge gate 5 and the water transfer gate 7 can adopt existing known technologies. Specifically, in this embodiment, three energy-dissipating water-dividing walls are evenly spaced on the left and right on the bottom plate two, and are connected to the leftmost one. There is a sand discharge gate 5 between the downstream of the water-retaining overflow wall 3 on the left side of the energy-dissipating water-dividing wall 2 and the downstream of the left side wall 1, which is connected to the leftmost energy-dissipating water-dividing wall 2.

A sand discharge gate 5 is connected to the energy-dissipating water diversion wall 2 on the far right.

The upstream of slope section 13 is connected to the downstream of base plate one 11, and the upstream of plane section 14 is connected to the downstream of slope section 13. , the height of the slope section 13 increases sequentially from its upstream to the downstream, and the sand discharge gate 5 and the water transfer gate 7 are both located above the plane section 14 and close to the downstream of the slope section 13 . Since the slope section 13 adopts an inverse slope design, large-size sand and gravel gather to a low point upstream of the slope. This not only greatly enhances the energy dissipation effect of the water flow in the energy-dissipating sand removal chamber 6, but also prevents large-size sand from Sand and gravel hit the sand discharge gate 5.
