Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy construction, in particular to a water conservancy construction cofferdam device. Background Technique

[0002] In the construction of water conservancy, a cofferdam is generally set up to block the water flow, which is convenient for construction workers to carry out construction. When building the cofferdam, in order to ensure the overall firmness, steel bars are generally driven into the ground, and at the same time, cement is poured between the assembly plates, which results in a long construction time for the cofferdam;

[0003] However, since the water surface height of the river channel changes with seasons and climate, in order to adapt to the changes in the river channel, an inflatable cofferdam is generally installed above the cofferdam. The inflatable cofferdam expands by inflating, so that its edge fits with the edge of the upper side of the cofferdam. Thus, the inflatable cofferdam can block the water in the river channel. At the same time, since the inflatable cofferdam can be quickly inflated and expanded, the inflatable cofferdam can be used to temporarily intercept the river channel during floods;

[0004] After the inflatable cofferdam is inflated, the inflation hole of the inflatable cofferdam cannot be quickly blocked, which leads to excessive gas leakage inside the inflatable cofferdam. Further, the edge of the inflatable cofferdam cannot fit with the connected object, resulting in the fact that the inflatable cofferdam cannot completely block the river water.

[0005] In view of the above situation, we propose a water conservancy construction cofferdam device. Content of the Utility Model

[0006] The purpose of the utility model is to solve the defects existing in the prior art, and a water conservancy construction cofferdam device is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A water conservancy construction cofferdam device includes an inflatable rubber dam. A sealing plate is fixedly connected to the outer surface of the inflatable rubber dam. A hollow cylinder is fixedly connected to the outer surface of the bottom of the sealing plate. A moving cylinder with an opening facing the sealing plate is slidably connected inside the hollow cylinder. A spring is fixedly connected to the inner wall of the moving cylinder in the direction facing the sealing plate. A connecting inflatable cylinder fixedly connected to the inner wall of the moving cylinder is arranged inside the spring. The upper end of the connecting inflatable cylinder penetrates through the sealing plate and is slidably connected to the sealing plate. A connecting sleeve is fixedly connected to the top end of the connecting inflatable cylinder. A sealing plug is threadedly connected inside the connecting sleeve;

[0009] A positioning ring with an opening facing the inflatable rubber dam is rotatably connected inside the sealing plate. Tooth grooves are formed on the outer surface around the positioning ring;

[0010] One side of the sealing plate is provided with a movable cavity, inside which a clamping block is slidably connected. A toothed block is arranged on one side of the clamping block close to the positioning ring and meshes with the tooth grooves around the positioning ring. A limiting screw rod is threadedly connected through the lower part of the clamping block.

[0011] Two groups of positioning blocks are fixedly connected to the outer surface of the connecting sleeve relatively. Positioning grooves are penetrated and arranged at the positions of the positioning ring corresponding to the positioning blocks.

[0012] The hollow cylinder is penetrated and provided with first ventilation holes. Second ventilation holes are arranged at the positions of the moving cylinder and the connecting inflation cylinder corresponding to the first ventilation holes.

[0013] Preferably, transverse fixing belts are fixedly connected to the front and rear ends of the inflatable rubber dam.

[0014] Preferably, vertical fixing belts with equal intervals are fixedly connected to both sides of the inflatable rubber dam. The vertical fixing belts and the sealing plate are on the same horizontal line.

[0015] Preferably, the inner wall of the sealing plate corresponding to the movable cavity is rotatably connected to the limiting screw rod. One end of the limiting screw rod away from the positioning ring penetrates through the sealing plate and extends to the outside of the sealing plate and is fixedly connected with a handle.

[0016] Preferably, a limiting groove is penetrated and arranged in the direction perpendicular to the first ventilation hole of the hollow cylinder. A limiting block is slidably connected inside the limiting groove. The limiting block is fixedly connected to the outer surface of the moving cylinder.

[0017] Preferably, the top end of the spring is fixedly connected to the outer surface of the bottom of the sealing plate.

[0018] Preferably, the cavity inside the positioning ring is a cylinder, and the diameter of the cavity is matched with the distance between the two groups of positions.

[0019] A kind of water conservancy construction cofferdam device proposed by the utility model has the beneficial effects that: after inflation is completed, the user can limit the position of the positioning ring by rotating the limit screw rod. When the positioning ring rotates, when the positioning groove does not coincide with the positioning block, the positioning ring can limit the position of the connecting sleeve, so that the inflatable rubber dam will not leak air during use. When the user separates the output end of the high-pressure air pump from the connecting sleeve, the force that the spring expands outwards disappears, so that the spring rebounds inwards to drive the connecting sleeve to move, so that the second ventilation hole inside the moving cylinder can be quickly blocked, preventing too much gas from escaping from the inflation port, and then making the edge of the inflatable rubber dam fit with the edge of the river channel, so that the inflatable rubber dam can completely block the river water; when the inflatable cofferdam is in use, the user first rotates the limit screw rod so that the position of the positioning ring can rotate, adjusts the position of the positioning ring so that the positioning groove and the positioning ring do not coincide, and finally the user limits the position of the positioning ring through the limit screw rod, further achieving the purpose of positioning the connecting sleeve, so that the connecting sleeve will not move under the influence of external forces, thereby preventing air leakage during the use of the inflatable rubber dam.

[0027] A sealing plate 4 is fixedly connected to the outer surface of the inflatable rubber dam 1. A hollow cylinder 5 is fixedly connected to the outer surface of the bottom of the sealing plate 4. The hollow cylinder 5 is provided with a limiting groove 6 penetrating in a direction perpendicular to the first ventilation hole 20. A limiting block 7 is slidably connected to the inside of the limiting groove 6. The limiting block 7 is fixedly connected to the outer surface of the moving cylinder 8. The moving cylinder 8 with an opening facing the sealing plate 4 is slidably connected to the inside of the hollow cylinder 5. A spring 9 is fixedly connected to the inner wall of the moving cylinder 8 facing the sealing plate 4. A connecting inflatable cylinder 10 fixedly connected to the inner wall of the moving cylinder 8 is arranged inside the spring 9. The top of the spring 9 is fixedly connected to the outer surface of the bottom of the sealing plate 4. The upper end of the connecting inflatable cylinder 10 penetrates the sealing plate 4 and is slidably connected to the sealing plate 4. The top of the connecting inflatable cylinder 10 is fixedly connected to a connecting sleeve 11. A sealing plug 12 is threadedly connected to the inside of the connecting sleeve 11; A positioning ring 13 with an opening facing the inflatable rubber dam 1 is rotatably connected to the inside of the sealing plate 4. The cavity inside the positioning ring 13 is a cylinder, and the diameter of the cavity is matched with the distance between the two positioning blocks 14. Tooth grooves 16 are formed on the outer surface around the positioning ring 13; An activity cavity 17 is formed on one side of the sealing plate 4. A clamping block 18 is slidably connected to the inside of the activity cavity 17. A tooth block is arranged on the side of the clamping block 18 close to the positioning ring 13 and meshes with the tooth grooves 16 around the positioning ring 13. A limiting screw rod 19 is threadedly connected to the lower part of the clamping block 18 and penetrates through. The inner wall of the sealing plate 4 corresponding to the activity cavity 17 is rotatably connected to the limiting screw rod 19. One end of the limiting screw rod 19 away from the positioning ring 13 penetrates the sealing plate 4 and extends to the outside of the sealing plate 4 and is fixedly connected to a handle; Two positioning blocks 14 are fixedly connected to the outer surface of the connecting sleeve 11 relatively. Positioning grooves 15 are formed in the positioning ring 13 corresponding to the positions of the positioning blocks 14; The hollow cylinder 5 is provided with a first ventilation hole 20. Second ventilation holes 21 are formed in the positions of the moving cylinder 8 and the connecting inflatable cylinder 10 corresponding to the first ventilation hole 20. When the bottom of the moving cylinder 8 is attached to the hollow cylinder 5, the positions of the first ventilation hole 20 and the second ventilation hole 21 can be made to coincide, so that the air pump can pump gas into the inside of the inflatable cofferdam.

[0028] In summary: During the application of the present utility model, when installing the inflatable cofferdam, the user first connects the horizontal fixing belt 3 and the vertical fixing belt 2 to the river channel, so that the inflatable cofferdam is transversely separated in the middle of the river channel; when inflating, the user first opens the sealing plug 12, and at the same time rotates the limit screw rod 19 counterclockwise to drive the clamping block 18 to move outward, so that the positioning ring 13 can rotate. The user rotates the positioning ring 13 until the positions of the positioning groove 15 and the positioning block 14 coincide. Then, the user inserts the output end of the high-pressure air pump into the connecting sleeve 11 and presses down, so that the connecting sleeve 11 drives the connecting inflatable cylinder 10 to slide downward, and then drives the moving cylinder 8 to move downward until the bottom of the moving cylinder 8 fits with the hollow cylinder 5, so that the positions of the first ventilation hole 20 and the second ventilation hole 21 coincide. After that, first rotate the positioning ring 13 to limit the position of the connecting sleeve 11, and then rotate the limit screw rod 19 to drive the clamping block 18 to move to limit the position of the positioning ring 13, so that the air pump can pump gas into the interior of the inflatable cofferdam; when the inflation is over, the user first rotates the limit screw rod 19 to drive the clamping block 18 to move, so that the position of the positioning ring 13 can be rotated. The user adjusts the position of the positioning ring 13 so that the positioning block 14 coincides with the positioning groove 15. Finally, the user separates the output end of the high-pressure air pump from the connecting sleeve 11. After that, the force for the spring 9 to expand outward disappears, so that the spring 9 rebounds inward to drive the connecting sleeve 11 to move, blocking the second ventilation hole 21 inside the moving cylinder 8, and thus blocking the inflation port of the inflatable rubber bag 1. Finally, the user first rotates the limit screw rod 19 so that the position of the positioning ring 13 can be rotated, adjusts the position of the positioning ring 13 so that the positioning groove 15 and the positioning ring 13 do not coincide, and finally rotates the limit screw rod 19 to limit the position of the positioning ring 13, further achieving the purpose of positioning the connecting sleeve 11, so that the connecting sleeve 11 will not move under the influence of external forces, thereby preventing air leakage during the use of the inflatable rubber dam.
