Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a leak-proof sealing device for water conservancy engineering gates. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature in order to achieve the purpose of eliminating harm and promoting benefits. Only by building water conservancy projects can water flow be controlled, floods be prevented, and water volume be regulated and distributed to meet the water needs of people's lives and production. When irrigating farmland, gates need to be built in the irrigation canals to control the water flow.

[0003] Some of the gates currently in use do not have the function of preventing water from leaking from both sides. When the gate is closed and there is a gap on both sides, water may leak from both sides, causing water flow control failure and affecting the normal operation of the water conservancy project. Leaking water means a waste of water resources. Due to the failure of water flow control caused by leakage, the water conservancy project may need more energy to maintain normal operation, thereby increasing operating costs. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 As shown, a leak-proof sealing device for a hydraulic engineering gate includes a gate body 1. Protective covers 2 are bolted to both sides of the gate body 1. A transmission plate 3 is slidably connected to the inner wall of the protective cover 2. The surface of the transmission plate 3 has three mounting grooves 4, which are equally spaced. A transmission mechanism 5 is installed inside the protective cover 2. The transmission mechanism 5 works in conjunction with the transmission plate 3. When the transmission mechanism 5 operates, it can move the transmission plate 3. A slot 6 is provided on one side of the surface of the transmission plate 3, and a waterproof rubber plate 7 is provided on one side of the transmission plate 3. One side of the surface of the waterproof rubber plate 7 has a T-shaped design, and the inner wall of the slot 6 also has a T-shaped design. This design allows for easy... The waterproof rubber plate 7 is inserted into the slot 6. A groove 8 is provided on one side of the surface of the protective cover 2. A limiting mechanism 9 is provided on one side of the protective cover 2. The limiting mechanism 9 works in conjunction with the groove 8. Under the action of the groove 8, the internal parts of the limiting mechanism 9 can run more stably. When the internal parts of the limiting mechanism 9 move to the appropriate position, the top of the slot 6 can be blocked. This prevents the waterproof rubber plate 7 from moving easily. When the transmission plate 3 moves, the waterproof rubber plate 7 can move. When the waterproof rubber plates 7 on both sides move to the appropriate position, they can fit against the two sides of the surface of the gate body 1. This action can prevent gaps from appearing on the side of the gate body 1, which would cause water leakage.

[0024] The transmission mechanism 5 includes a screw rod 51, the bottom of which is rotatably connected to one side of the top of the protective cover 2. A connecting rod 52 is bolted to one end of the surface of the screw rod 51. The bottom of the connecting rod 52 is rotatably connected to the bottom of the inner wall of the protective cover 2. When the screw rod 51 rotates, the connecting rod 52 can rotate. A bevel gear set 53 is bolted to the surface of the connecting rod 52. The bevel gear set 53 consists of two bevel gears. There are three bevel gear sets 53, and they are located on the same horizontal plane as the mounting groove 4. When the connecting rod 52 rotates, the three bevel gear sets 53 on the three sides can rotate. A lead screw 54 is bolted to one side of the surface of another bevel gear in the bevel gear set 53. When the bevel gear set 53 rotates, the lead screw 54 can rotate. A connecting sleeve rod 55 is threaded to the surface of the lead screw 54. One end of the surface of the connecting sleeve rod 55 is bolted to one side of the inner wall of the mounting groove 4. When the lead screw 54 rotates, the connecting sleeve rod 55 can move. When the three connecting sleeve rods 55 move, the transmission plate 3 can move.

[0025] The limiting mechanism 9 includes a mounting bracket 91. One side of the surface of the mounting bracket 91 is bolted to one side of the surface of the protective cover 2. A threaded rod 92 is threadedly connected to the inner wall of the mounting bracket 91. When the threaded rod 92 rotates, it can move along the inner wall of the mounting bracket 91. A baffle 93 is rotatably connected to one end of the surface of the threaded rod 92. A guide block 94 is bolted to one side of the surface of the baffle 93. The surface of the guide block 94 is slidably connected to the inner wall of the slide groove 8. When the threaded rod 92 rotates, the baffle 93 can move. When the baffle 93 moves, the guide block 94 can slide along the inner wall of the slide groove 8. Under the action of the guide block 94, the movement of the baffle 93 can be more stable. When the baffle 93 moves to the appropriate position, it can block the top of the slot 6.

[0026] Working principle: When it is necessary to prevent water leakage due to gaps between the gate and the inner walls of both sides of the frame in the gate body 1, rotate the screw rods 51 on both sides respectively. When the screw rods 51 rotate, the connecting rods 52 rotate. Then, the connecting rods 52 rotate, which in turn rotates the bevel gear sets 53 on three sides. Next, the rotation of the bevel gear sets 53 drives the lead screw 54 to rotate. When the lead screw 54 rotates, the connecting sleeve rods 55 move. Then, when the connecting sleeve rods 55 on three sides move, the transmission plate 3 moves. Next, the movement of the transmission plate 3 drives the waterproof rubber plate 7 to move. When the waterproof rubber plates on both sides move... When moved to the appropriate position, the gap between the gate body 1 and the inner walls of both sides of the frame can be blocked, thus preventing water leakage. When the waterproof rubber sheet 7 needs to be replaced, rotate the threaded rod 92. When the threaded rod 92 rotates, it can move along the inner wall of the mounting bracket 91. Then, the movement of the threaded rod 92 can drive the baffle 93 to move. Next, the movement of the baffle 93 can drive the guide block 94 to slide along the inner wall of the slide groove 8. When the baffle 93 moves to the appropriate position, the blockage on the top of the slot 6 can be released, and then the waterproof rubber sheet 7 can be pulled out from the inside of the slot 6.
