Description

Technical Field

[0001] This utility model relates to the technical field of flood control equipment for water conservancy and hydropower projects, specifically to a top-drop type flood control and water-blocking device for water conservancy and hydropower projects. Background Technology

[0002] Hydropower projects are crucial national infrastructure, undertaking multiple tasks including flood control, power generation, water supply, and irrigation. Among these, flood control safety is the core element in ensuring the safety of the projects themselves and the lives and property of people downstream. During the flood season, to prevent floodwaters from flowing back through key areas such as underground powerhouses, corridors, and passageway entrances, effective water-blocking facilities must be used for sealing. Therefore, developing reliable and efficient flood control and water-blocking devices is of great significance for improving the disaster prevention and mitigation capabilities of hydropower projects.

[0003] Currently, in water conservancy and hydropower projects and similar scenarios, traditional flood control and water-blocking methods mainly include stacking sandbags and installing prefabricated water-blocking panels. Stacking sandbags is the most common method, where workers manually transport woven bags filled with sand to the channel entrance and stack them layer by layer to form a water-blocking wall. Prefabricated water-blocking panels, on the other hand, usually have pre-set installation slots at the channel entrance. When floods occur, workers insert or splice multiple independent water-blocking panels one by one into the slots to form a continuous water-blocking barrier.

[0004] The aforementioned flood control and prevention methods are inefficient and have a slow emergency response. Whether it is transporting and stacking sandbags or assembling barriers on site, they consume a lot of manpower and time. In the face of sudden floods, the best opportunity to block the flood may be missed. They are highly dependent on manpower and pose safety risks. The pre-set installation slots or the large number of sandbags that are always on hand will take up space, affect the normal passage of vehicles and pedestrians, and affect daily traffic and aesthetics. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a top-drop flood control and water-blocking device for water conservancy and hydropower projects, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a top-drop type flood control and water-blocking device for water conservancy and hydropower projects, including a fixed rail. A support mechanism is provided on the top of the fixed rail. The support mechanism includes a pad that is hinged to the inner side wall of the fixed rail. A first connecting rod is fixed on one side of the fixed rail. A third placement groove is opened at one end of the first connecting rod. A hydraulic rod is hinged inside the third placement groove. The top end of the hydraulic rod is hinged to the bottom of the pad. Second connecting rods are fixed on both sides of the outer wall of one end of the first connecting rod. A pad block is fixed on the top of the second connecting rod.

[0007] Furthermore, a first fixing hole is provided through the top of the fixed rail, and multiple first fixing holes are provided, which are arranged horizontally and equidistantly.

[0008] Furthermore, the second connecting rod and the top of the pad are both provided with a second mounting hole, the pad is arranged in a trapezoidal shape, and the bottom of the pad is provided with a first placement groove, the bottom of the first placement groove abutting against the top of the pad.

[0009] Furthermore, a second placement groove is provided on the top of the pad. The second placement groove is T-shaped. A first connecting shaft is fixed to one end of the second placement groove, and a pressure switch is fixed to the end of the second placement groove near the first connecting shaft.

[0010] Furthermore, a second connecting shaft is rotatably connected to the outer wall of the first connecting shaft. A float is fixed at one end of the second connecting shaft. The float is located inside the other end of the second placement groove. The float is hollow. An LED bead is fixed inside the float. The horizontal height of the top of the float is less than the horizontal height of the top of the pad. The LED bead is electrically connected to the pressure switch.

[0011] Furthermore, a rubber baffle is fixed to the top of the inner wall of the fixed rail, and one side of the rubber baffle is fixed to the top of the pad near the fixed rail. The rubber baffle is arranged in an arc shape.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This application embeds a fixed rail and support mechanism into a pre-set groove in the ground, so that the mat remains flush with the ground during the non-flood season, without affecting the normal passage of vehicles and people, and has a good aesthetic appearance. During the flood season, the hydraulic rod quickly lifts the mat to a vertical state to form a water barrier. It has a high degree of automation, greatly reducing reliance on manpower and operational risks. The mat is supported by pad blocks to prevent the top of the mat from being deformed due to excessive pressure when it is laid flat later. It does not affect the normal passage effect while ensuring the service life.

[0013] 2. In this application, during flood control, water flows into the second placement groove on the top of the pad. Under the action of the buoyancy of the water flow, the float rotates around the first connecting shaft. When the float touches the pressure switch fixed at one end of the second placement groove, the pressure switch is triggered, causing the lamp to light up, realizing the automatic warning function and reminding personnel that the water level has risen to the warning position, thereby achieving the effect of automatic warning during flood control.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0019] This application discloses a top-drop type flood control and water-blocking device for water conservancy and hydropower projects, including a fixed rail 1. A support mechanism 20 is provided on the top of the fixed rail 1. The support mechanism 20 includes a pad 21 hinged to the inner wall of the fixed rail 1. A first connecting rod 4 is fixed on one side of the fixed rail 1. A third placement groove 9 is opened at one end of the first connecting rod 4. A hydraulic rod 5 is hinged inside the third placement groove 9. The top end of the hydraulic rod 5 is hinged to the bottom of the pad 21. Second connecting rods 6 are fixed on both sides of the outer wall of one end of the first connecting rod 4. A pad block 8 is fixed on the top of the second connecting rod 6. Multiple support mechanisms 20 are provided. When flood control is required, the hydraulic rods 5 inside the multiple support mechanisms 20 are controlled to extend. While the hydraulic rods 5 extend, they change the angle between themselves and the first connecting rod 4 and the pad 21 until the pad 21 is perpendicular to the ground.

[0020] Reference Appendix Figure 1 The top of the fixed rail 1 is provided with a first fixing hole 3. There are multiple first fixing holes 3, which are arranged horizontally and equidistantly. During installation, holes of the corresponding size of the fixed rail 1 and the support mechanism 20 are first dug in the ground of the flood control area. Then, expansion bolts are used to pass through the first fixing holes 3 to fix the fixed rail 1 to the ground.

[0021] Reference Appendix Figure 2 The second connecting rod 6 and the pad 8 are both provided with a second mounting hole 7. The pad 8 is set in a trapezoidal shape. The bottom of the pad 21 is provided with a first placement groove 22. The bottom of the first placement groove 22 is in contact with the top of the pad 8. The pad 8 supports the pad 21 to prevent the top of the pad 21 from being deformed due to excessive pressure when it is laid flat later.

[0022] Reference Appendix Figure 3 The pad 21 has a second placement groove 23 on its top. The second placement groove 23 is T-shaped. A first connecting shaft 24 is fixed to one end of the second placement groove 23. A pressure switch 26 is fixed to the end of the second placement groove 23 near the first connecting shaft 24. The pressure switch 26 is located on the side above the first connecting shaft 24.

[0023] Reference Appendix Figure 3 and 4The first connecting shaft 24 is rotatably connected to the outer wall of the second connecting shaft 25. A float 27 is fixed to one end of the second connecting shaft 25. The float 27 is located inside the other end of the second placement groove 23. The float 27 is hollow and has an LED bead 28 fixed inside it. The horizontal height of the top of the float 27 is less than the horizontal height of the top of the pad 21. The LED bead 28 is electrically connected to the pressure switch 26. During flood prevention, the pad 21 is erected, and water flows through the float 27. Due to buoyancy, the float 27 moves downward, causing the first connecting shaft 24 to rotate. When the first connecting shaft 24 touches the pressure switch 26, it stops rotating. At this time, the pressure switch 26 receives pressure and sends a signal to control the LED bead 28 to light up. When flood prevention is not needed, the pad 21 is reset, and the float 27 returns to the second placement groove 23 due to gravity and is located inside the second placement groove 23. When an object passes over the top of the pad 21, it will not directly touch the float 27 and cause it to be damaged.

[0024] Reference Appendix Figure 1 A rubber baffle 10 is fixed to the top of the inner wall of the fixed rail 1. One side of the rubber baffle 10 is fixed to the top of the pad 21 near the fixed rail 1. The rubber baffle 10 is arc-shaped. The rubber baffle 10 is used to fill the gap between the fixed rail 1 and the pad 21 to prevent some hard impurities from entering the interior and affecting the subsequent rotation of the pad 21.

[0025] The workflow of this utility model is as follows: Under normal conditions, the pad 21 of the support mechanism 20 is horizontally positioned by the retraction of the hydraulic rod 5. The first placement groove 22 at its bottom abuts against the top of the pad 8 fixed to the top of the second connecting rod 6. The float 27 is located inside the pad 21, making its top basically flush with the top surface of the pad 21, without affecting the normal passage of vehicles and pedestrians. When flood prevention is required, the hydraulic rod 5 is extended, pushing the pad 21 to rotate around it and the fixed rail 1. The angle between the hydraulic rod 5, the first connecting rod 4, and the pad 21 changes continuously until the pad 21 is lifted to a position perpendicular to the ground. At the same time, the pad 21 rotates with the water level. As the water level rises, it flows into the second placement groove 23 at the top of the pad 21. Under the buoyancy of the water flow, the float 27 rotates around the first connecting shaft 24. When the float 27 touches the pressure switch 26 fixed at one end of the second placement groove 23, the pressure switch 26 is triggered, causing the lamp 28 to light up, realizing the automatic warning function and reminding personnel that the water level has risen to the warning position. After the flood season ends, the control hydraulic rod 5 retracts, and the pad 21 resets. During this process, the float 27 automatically rotates back due to gravity, disengages from the pressure switch 26, the lamp 28 goes out, and re-enters the second placement groove 23, once again providing a flat surface for daily passage.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
