Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a water stopping device for water conservancy project construction. Background Art

[0002] Water conservancy projects are a general term for projects such as flood control, drainage, irrigation, power generation, water supply, reclamation, soil and water conservation, immigration, and water resource protection (including new construction, expansion, reconstruction, reinforcement, and repair) and their supporting and ancillary projects. They are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects.

[0003] Water is a valuable resource that is indispensable to human production and life. Therefore, canals are built for drainage and water diversion to irrigate crops, etc. However, during the drainage process, when construction projects or construction projects are carried out on the canals, the water needs to be stopped. Therefore, a water-stopping device for water conservancy project construction is needed. However, the water-stopping device in the existing technology uses special materials to firmly fix the water stop plate and the inner wall of the canal in terms of sealing. Although this method has good sealing performance, it is extremely troublesome to disassemble, and the height of the water stop plate will not be increased as the water level rises.

DETAILED DESCRIPTION

[0023] like Figure 1-7 As shown, this specific embodiment adopts the following technical solutions: Example

[0024] The cam 14 is connected to the second cam 15 by the second cam 16 and the cam 17 is connected to the first cam 15 by the second cam 16. The cam 14 is connected to the second cam 15 by the second cam 16. The bottom of the second plate 15 is fixedly connected to the base 27, and a third movable plate 36 is provided on both sides of the base 27. A third rotating shaft 37 is provided inside the base 27. The third movable plate 36 is rotatably connected to the third rotating shaft 37. The third rotating shaft 37 on both sides of the base 27 is rotatably connected to the third movable plate 36, so that the third movable plate 36 can be rotated freely around the third rotating shaft 37 as the center, so that it fits with the inner wall of the canal. One end of the third movable plate 36 is fixedly connected to the second rubber plate 35, which can better seal with the inner wall of the canal. A water discharge mechanism 47 is provided on the first plate 1. After the project is completed, the water discharge mechanism 47 is used to drain the water and then disassemble the device. A fixing mechanism 28 is provided on the base 27, and the base 27 is tightly fitted and sealed with the ground through the fixing mechanism 28. A lifting plate 7 is provided on one side of the first plate 1, which is raised and lowered with the water level by the lifting plate 7, thereby solving the problem of rising water level.

[0025] The water discharge mechanism 47 includes a first rotating column 29, which is rotatably connected to the first plate 1. A drain port 3 is provided inside the first plate 1, and a baffle 2 is provided inside the drain port 3. The baffle 2 is fixedly connected to the first rotating column 29. A second groove 48 is provided inside the first plate 1. The top of the first rotating column 29 is fixedly connected to the gear 44 located inside the second groove 48. The inner side of the second groove 48 is rotatably connected to the second rotating column 31. The outer side of the second rotating column 31 is fixedly connected to the half gear 30, and the half gear 30 is meshed with the gear 44. A first groove 43 is provided inside the first plate 1, and a spring 42 is fixedly connected to the inner side of the first groove 43. One end of the spring 42 is fixedly connected to a pull rod 39. If water needs to be drained, the pull rod 39 is pulled to move the second wedge 46 into the first groove 43. After the first wedge 45 on the half gear 30 is no longer restricted by the second wedge 46, the half gear 30, the second rotating column 31, the gear 44, the first rotating column 29 and the baffle 2 are no longer restricted, the force brought by the water pressure will automatically open the baffle 2, so that the baffle 2 drives the first rotating column 29 to rotate.

[0026] Among them, the fixing mechanism 28 includes a first fixing plate 16, a base 27 and a second plate 15 that are detachably connected, a fixing block 17 fixedly connected to the bottom of the first fixing plate 16, a fixing column 25 fixedly connected to the bottom of the fixing block 17 and passing through the base 27, a second fixing plate 19 fixedly connected to the bottom of the first fixing plate 16, a screw rod 20 connected to the internal thread of the second fixing plate 19, one end of the screw rod 20 fixedly connected to the rotating disk 18, one end of the screw rod 20 rotatably connected to the shaft disk 21, a trapezoidal block 22 fixedly connected to one side of the shaft disk 21, a third slider 23 fixedly connected to the bottom of the trapezoidal block 22, and a top of the base 27. A third slide groove 24 is provided, and the third slider 23 is slidably connected to the third slide groove 24. A sealing rubber 26 is provided at the bottom of the base 27, and the rotating disk 18 can be rotated so that the screw rod 20 pushes the shaft disk 21 and the trapezoidal block 22 at one end to be squeezed between the fixed block 17 and the base 27 according to the threaded connection with the second fixed plate 19. Since the fixed column 25 is fixed to the ground, the trapezoidal block 22 will not cause the fixed block 17 at the top of the fixed column 25 and the first fixed plate 16 to rise as a whole due to the squeezing force, so the base 27 will be pressed down as a whole, and the sealing rubber 26 will be squeezed by the base 27 and fit tightly to the ground.

[0027] Among them, a first slide groove 11 is provided on one side of the first plate 1, and a first slider 12 is slidably connected to the inside of the first slide groove 11. The first slider 12 and the lifting plate 7 are fixedly connected. A limiting groove 40 is provided on the inner side of the first slide groove 11, and a limiting block 41 is slidably connected to the inside of the limiting groove 40. The limiting block 41 is fixedly connected to the first slider 12. The lifting plate 7 can be lifted and lowered through the sliding connection between the first slider 12 and the first slide groove 11. The existence of the limiting block 41 and the limiting groove 40 prevents the lifting plate 7 from being lifted to a certain height so that the first slider 12 and the first slide groove 11 are disengaged. A second movable plate 6 is provided on both sides of the lifting plate 7, and a first rotating shaft 9 is provided inside the lifting plate 7. The second movable plate 6 is rotatably connected to the first rotating shaft 9. A sliding groove 33 is provided at one end of the second movable plate 6. The sliding groove 33 is slidably connected to the sliding protrusion 32. The first rotating shaft 9 on both sides of the lifting plate 7 is rotatably connected to the second movable plate 6, so that the second movable plate 6 can be rotated freely according to the first rotating shaft 9 as the center, and can better fit the inner wall of the canal. The second movable plate 6 is connected to the first rubber plate 34 through the sliding protrusion 32 and the sliding groove 33.

[0028] A drainage channel 4 is provided inside the first plate 1 , and a valve 38 is provided inside the drainage channel 4 . By opening the valve 38 , some water flows out of the drainage channel 4 first, causing the water pressure on one side of the first plate 1 to drop.

[0029] Among them, a first wedge 45 is fixedly connected to the outer side of the half gear 30, and a second wedge 46 is fixedly connected to one side of the pull rod 39. Through the second wedge 46, the first wedge 45, the half gear 30, the second rotating column 31 and the gear 44 are restricted by it, so that the first rotating column 29 and the baffle 2 are restricted from rotating.

[0030] A float 8 is fixedly connected to one side of the lifting plate 7 , and the buoyancy of the float 8 in the water causes the lifting plate 7 to rise and fall as a whole along with the water level.

[0031] The method for using the water-stopping device for water conservancy project construction comprises the following steps:

[0032] S1. First, pass the fixing column 25 through the base 27 and fix it to the ground. Then, rotate the rotating disk 18 so that the screw rod 20, according to the threaded connection with the second fixing plate 19, pushes the shaft disk 21 and the trapezoidal block 22 at one end to be squeezed between the fixing block 17 and the base 27. Since the fixing column 25 is fixed to the ground, the trapezoidal block 22 will not cause the fixing block 17 and the first fixing plate 16 at the top of the fixing column 25 to rise as a whole due to the squeezing force. Therefore, the base 27 will be pressed down as a whole, and the sealing rubber 26 will be squeezed by the base 27 and tightly adhered to the ground.

[0033] S2. Then, install the second plate 15 on the base 27, and then use the second slider 13 and the second chute 14 to install the first plate 1 on one side of the second plate 15. Then, use the first slider 12 and the first chute 11 to install the lifting plate 7 on one side of the first plate 1. The limiting groove 40 and the limiting block 41 prevent the lifting plate 7 from being separated from the first plate 1 as a whole due to the high water level. After installation, the rotation relationship between the third rotating shaft 37 and the third movable plate 36 is used to make the second rubber plate 35 at one end contact the water. The inner wall of the canal is fitted, and the rotation relationship between the second rotating shaft 10 and the first movable plate 5 is used to make the first rubber plate 34 at one end fit the inner wall of the canal. The rotation relationship between the first rotating shaft 9 and the second movable plate 6 is used to make the sliding protrusion 32 on the first rubber plate 34 fit and slide with the sliding groove 33. When there is water on one side of the device, the water brings pressure to the second movable plate 6, the first movable plate 5 and the third movable plate 36, making them fit more tightly with the inside of the canal. When the water level rises, the lifting plate 7 as a whole rises with the water level through the floating object 8;

[0034] S3. When the water needs to be drained after the end, the valve 38 can be opened first to allow a small amount of water to flow out from the drain channel 4, so that the water pressure on the side of the first plate 1 is reduced a little, and then the pull rod 39 is pulled to move the second wedge 46 into the first groove 43. After the first wedge 45 on the half gear 30 is no longer restricted by the second wedge 46, the half gear 30, the second rotating column 31, the gear 44, the first rotating column 29 and the baffle 2 are no longer restricted, the water will automatically flush the baffle 2, causing the baffle 2 to rotate according to the first rotating column 29.
