Description

Technical Field

[0001] This utility model relates to the field of water conservancy dam technology, specifically to a waterproof structure water conservancy dam. Background Technology

[0002] A dam is a type of hydraulic structure. It is an engineering measure taken on a river channel to develop and utilize the water resources of a river. A dam is a hydraulic structure that can control and dominate the flow of water. Water conservancy dams play an extremely important role in water storage and flood discharge. The development of water conservancy dams has brought great convenience to water conservancy projects.

[0003] A search revealed that patent application CN215948105U discloses a waterproof structure for a water conservancy dam. The dam's main body has a steel frame in the middle, with a limiting groove at the bottom and a gate plate connected to the inner side of the steel frame. A rotating shaft is connected at both ends to the inner wall above the steel frame and is movably connected to the top of a material receiving frame. The material receiving frame has lifting rings fixed to its two sides, which are connected to the output end of a hydraulic rod. This allows the material receiving frame to filter and clean water plants and debris.

[0004] However, due to the design of the dam body and steel frame, the sides of the dam body are vertical, resulting in a small contact area with the water flow. This leads to a large impact force on a single volume. The middle part of the dam body is only protected by the steel frame, resulting in low overall strength, weak impact resistance, and a low safety factor. At the same time, due to the design of the material receiving rack, which is connected by hydraulic rods and shafts, the large area of ​​the dam results in a large size for the hydraulic rods and shafts. Moreover, being submerged in water for a long time, the hydraulic rods and shafts have a short service life and high cost.

[0005] Therefore, we propose a waterproof structure for hydraulic dams. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a waterproof structure for hydraulic dams, which solves the problems of low impact resistance and high operating costs of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a waterproof structure for a water conservancy dam, comprising a dam body, wherein a foundation is fixedly installed on the bottom surface of the dam body;

Two sets of buffer walls are fixedly installed on the top surface of the foundation. The buffer walls are constructed of reinforced concrete together with the foundation, and the angle between the buffer walls and the foundation is 45 degrees. The interior of the dam body and foundation is equipped with a water-proof layer, and the outer wall of the dam body is equipped with a waterproof geomembrane.

[0009] The dam body has three sets of opposing spillway holes, each equipped with a metal filter screen of the appropriate size. The top surface of the dam body is fixedly installed with two sets of opposing guardrails, and the outer wall of the guardrails is fixedly installed with evenly distributed hooks. The left side of the dam body is equipped with a weed-blocking net of the appropriate size, the top surface of the weed-blocking net is connected to the hooks, and the bottom surface of the weed-blocking net is fixedly installed with evenly distributed barbs.

[0010] Preferably, a support column is fixedly installed between the right side of the buffer wall and the foundation, which can support the buffer wall and ensure its stability and strength.

[0011] Preferably, the drain hole is equipped with a corresponding electromagnetic butterfly valve, and a monitoring and control house is fixedly installed on the top surface of the dam body. The monitoring and control house is equipped with a control button connected to the electromagnetic butterfly valve, so that the valve can be opened by controlling the control button in the monitoring and control house, which improves convenience.

[0012] Preferably, three sets of connecting cylinders, each connected to an electromagnetic butterfly valve, are fixedly installed on the top surface of the dam body. A threaded rod connected to the electromagnetic butterfly valve is rotatably connected inside the connecting cylinder, and a valve disc is fixedly installed at the top of the threaded rod. This allows the valve to be opened by manually rotating the valve disc, improving its practicality.

[0013] Preferably, the front and rear sides of the dam body are reinforced with concrete piers of appropriate specifications, and steps are installed between the reinforced piers and the dam body. This can limit and reinforce the dam body, and improve its stability and strength.

[0014] Preferably, the bottom surface of the weed barrier is fixedly installed with an iron plate of the same specifications, which ensures that the weed barrier sinks into the water and contacts the left side of the dam body.

[0015] 1. This water conservancy dam with a waterproof structure features a dam body and buffer walls. The left side of the dam body is sloped to increase the contact area with the water surface and reduce the impact force on a single volume. The two sets of buffer walls can buffer and weaken the impact force of the water flow, improve the overall impact resistance of the dam, and have a high safety factor.

[0016] 2. By using hooks, a weed barrier, and barbs, the top of the weed barrier is connected to the hooks. The weed barrier is then lowered and submerged in the water. When it is necessary to clear the weeds and debris on the left side of the dam, the weed barrier is pulled up. As the weed barrier moves upward, debris such as water troughs are caught on the barbs. The device is simple and has low operating costs. Attached Figure Description
