For example, the object "provided with" may be a part of the body, or may be arranged separately from the body and connected to the body, and the connection may be a detachable connection or an inseparable connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0030] The present invention is further described in detail below in conjunction with the embodiments.
[0031] Specific embodiments of the water conservancy and hydropower construction device provided by the utility model:
[0032] See also Figure 1-9 The water conservancy and hydropower construction device comprises an installation frame 10 and a vertically lifting gate plate 1; the installation frame 10 is a rectangular frame, which is installed on a dam body 12, and the inner side of the lower part of the installation frame 10 is for water flow to pass through. The inner sides of both sides of the installation frame 10 are provided with vertical slide grooves 11, and the edges of both sides of the gate plate 1 can slide vertically along the inner sides of the slide grooves 11.
[0033] In this embodiment, there is a cavity inside the gate plate 1, and an opening 2 connected to the cavity is provided at the lower part of the front wall of the gate plate 1. In this embodiment, the opening 2 is rectangular, the front wall of the gate plate 1 refers to its side wall facing the upstream of the water flow, and the rear wall of the gate plate 1 refers to its side wall facing the downstream of the water flow.
[0034] A horizontally movable plate 3 is provided at the front side of the opening 2. The movable plate 3 is a rectangular plate. The area of the movable plate 3 is larger than the area of the opening 2 and the centers thereof correspond. Specifically, a plurality of guide rods 6 are connected to the rear side of the movable plate 3. The guide rods 6 slide through the rear wall of the gate plate 1. The function of the guide rods 6 is to support the movable plate 3 to stably reciprocate horizontally and linearly. The rear wall of the gate plate 1 is provided with through holes corresponding to the guide rods 6 one by one for the guide rods 6 to pass through. A limit block is provided at the rear end of the guide rods 6 to prevent the guide rods 6 from being separated from the rear wall of the gate plate 1.
[0035] A telescopic sealing cover 4 surrounding the opening 2 is connected between the movable plate 3 and the front wall of the gate plate 1; the telescopic sealing cover 4 is a square tubular structure with pleats, which can be extended and contracted as the movable plate 3 moves. The telescopic sealing cover 4 can achieve sealing and prevent water from entering the internal cavity of the gate plate 1. The material of the telescopic sealing cover 4 can be waterproof pleated nylon cloth, pleated plastic, or pleated three-proof cloth.
[0036] The guide rods 6 are evenly arranged along the edge of the opening 2 and fit the inner side of the opening 2, that is, they are arranged at intervals in a rectangular frame shape; the rectangular frame-shaped arrangement of the guide rods 6 can support the telescopic sealing cover 4 from the inside, thereby preventing the telescopic sealing cover 4 from being severely retracted due to water pressure after being extended, thereby avoiding deformation and damage of the telescopic sealing cover 4; and ensuring that during the movement of the movable plate 3, the volume of the device undergoes linear and regular changes, thereby being able to obtain stable buoyancy.
[0037] A rod cover 7 is provided at the rear side of the gate plate 1, and the guide rods 6 are all located inside the rod cover 7. Figure 8 As shown, when the rod cover 7 is connected to the rear side of the gate plate 1, it blocks the rear side of the guide rod 6 to prevent the guide rod 6 from being exposed to the water environment, thereby preventing water from entering the cavity inside the gate plate 1 through the through hole in the rear wall of the gate plate 1, thereby ensuring the sealing of the device.
[0038] In order to ensure the stability of the internal air pressure after the volume of the device and the volume of the internal cavity change, a vent pipe 9 is provided on the upper side of the gate plate 1. The vent pipe 9 is connected with the internal cavity of the gate plate 1, thereby realizing the connection between the internal cavity and the outside and forming gas communication. The vent pipe 9 is arranged on the upper side of the gate plate 1 to prevent water from entering the internal cavity.
[0039] A driving member 5 for driving the movable plate 3 to move horizontally is installed on the gate plate 1. In this embodiment, the driving member 5 is a hydraulic cylinder, which is installed on the rear wall of the gate plate 1; specifically, the hydraulic cylinder passes through the rear wall of the gate plate 1, and a cylinder cover 8 is provided on the rear side of the gate plate 1. The rear end of the hydraulic cylinder is located in the cylinder cover 8, and the function of the cylinder cover 8 is similar to that of the rod cover 7: the cylinder cover 8 protects the rear end of the hydraulic cylinder to prevent water from entering the internal cavity from the connection between the hydraulic cylinder and the rear wall of the gate plate 1.
[0040] The hydraulic cylinder is connected to an external pump station through an oil supply pipeline, and the pump station can be set on the dam body 12. The oil supply pipeline passes through the vent pipe 9. The front end of the hydraulic cylinder, that is, the telescopic end, is connected to the rear side of the middle part of the movable plate 3. The rear side of the movable plate 3 is provided with radial reinforcement ribs, and the center of the reinforcement ribs is connected to the hydraulic cylinder to ensure strength and prevent deformation of the movable plate 3.
[0041] like Figure 1 As shown, when the telescopic sealing cover 4 is in the contracted state, the buoyancy of the gate plate 1 in the water is less than its own weight, so the gate plate 1 can move down to the bottom along the slide 11 to intercept the water flow;
[0042] The telescopic end of the hydraulic cylinder extends to move the movable plate 3 away from the front side of the gate plate 1, such as Fig. 9 As shown, the volume of the device increases, the displacement increases, the buoyancy in the water is greater than its own weight, the gate 1 can float in the water, move to the upper part of the mounting frame 10, and move to a part of the lower part of the gate 1 and the movable plate 3 immersed in the water to maintain relative balance, and the lower part of the gate 1 can be passed by water.
[0043] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
