Description

Technical Field

[0001] The utility model relates to the technical field of municipal pipeline maintenance, in particular to a plugging water stop device. Background Art

[0002] During the maintenance of municipal pipelines, in order not to affect the normal operation, it is necessary to plug and block water at the maintenance port to avoid interfering with the construction. The port of the municipal pipeline is blocked by inserting an inflatable rubber airbag. As the volume of the rubber airbag increases after inflation inside, it can fit with the inner wall of the pipeline to achieve water blocking. However, the airbag has elasticity. When the water pressure is too high, it will cause the water flow to break through the connection between the edge of the airbag and the inner wall of the pipeline, resulting in water leakage, and the plugging and water blocking effect is unstable, increasing the difficulty of the maintenance work of municipal pipelines. Content of the Utility Model

[0003] In view of this, the utility model provides a plugging water stop device, aiming to solve the above problems to at least a certain extent.

[0004] The technical solution of the utility model is realized as follows:

[0005] A plugging water stop device includes a fixing plate. An adjusting lead screw passes through between the two sides of the fixing plate. One end of the adjusting lead screw is sleeved with a water stop seat, and the other end of the adjusting lead screw is fixedly connected with a turntable. The adjusting lead screw is rotationally connected with the fixing plate through a self-locking bearing, and the adjusting lead screw is threadedly connected with the water stop seat.

[0006] As a further optional solution, a rubber sleeve is sleeved between the surfaces of the water stop seat far from the turntable. A plugging airbag is fixedly connected to one side of the water stop seat far from the turntable. The other side of the plugging airbag is communicated with an exhaust pipe, and an electromagnetic valve is installed on the exhaust pipe.

[0007] As a further optional solution, a plurality of rubber convex rings are evenly sleeved on the outer surface of the rubber sleeve from left to right by injection molding. Both the top and bottom of one side of the fixing plate are fixedly connected with telescopic rods. One end of each of the two telescopic rods passes through one side of the water stop seat and extends into the inside of the water stop seat. Both of the two telescopic rods have a limiting effect on the water stop seat, and the water stop seat is fixedly connected with the rubber sleeve.

[0008] As a further optional solution, gas delivery components are fixedly connected to both the upper and lower sides of one side of the fixing plate and located above and below the water stop seat. The air outlet ends of the two gas delivery components pass through the water stop seat and extend into the inside of the plugging airbag.

[0009] As a further alternative, the gas delivery assembly includes a mounting plate and a gas chamber. The mounting plate is fixedly connected to one side of the fixing plate. A gas pump is fixedly connected to one side of the mounting plate. The intake end of the gas pump is connected to an intake pipe. The gas chamber is formed between the two sides of the water blocking seat and is located inside the water blocking seat. The outlet end of the gas pump is connected to an outlet pipe. One end of the outlet pipe is connected to a corrugated expansion pipe. A delivery pipe is connected between one end of the corrugated expansion pipe and one end of the gas chamber. The other end of the gas chamber is connected to a connecting pipe. One end of the connecting pipe sequentially passes through the water blocking seat, the rubber sleeve, and the plugging airbag and extends into the interior of the plugging airbag.

[0010] As a further alternative, the water blocking seat is fixedly connected to the connecting pipe, and the connecting pipe is fixedly connected to the rubber sleeve.

[0011] As a further alternative, the connecting pipe is fixedly connected to the plugging airbag and is in communication with the plugging airbag.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By rotating the turntable to drive the adjusting screw rod to rotate, the water blocking seat and the plugging airbag can be sequentially pushed into the municipal pipeline. A rubber sleeve with a rubber convex ring is sleeved outside the water blocking seat, which can increase the friction between the water blocking seat and the inner wall of the pipeline, thereby expanding the water pressure range that the water blocking seat can withstand. Moreover, the water blocking seat and the plugging airbag provide double blockages to the water pipe, improving the water blocking effect of the pipeline blockage, reducing the phenomenon of water leakage, and improving the convenience of the municipal pipeline maintenance work.

[0014] 2. Since the water blocking seat is in a frustum shape, the water blocking seat can elastically clamp and seal pipelines with different diameters through the rubber sleeve. And the rubber convex ring can increase the friction of the rubber sleeve with the inner wall of the external water pipe. Moreover, the shape formed by multiple rubber convex rings is in a frustum shape, which can be adjusted and blocked appropriately according to the inner diameter of the water pipe along with the water blocking seat, effectively improving the adaptation range of the municipal pipeline blockage and water blocking, and saving the cost of municipal pipeline maintenance equipment.

[0025] Reference Figures 1-4 , an embodiment of the present application shows a plugging water stop, including a fixing plate 1. An adjusting lead screw 2 passes through between the two sides of the fixing plate 1. One end of the adjusting lead screw 2 is sleeved with a water blocking seat 3, and the other end of the adjusting lead screw 2 is fixedly connected with a turntable 5. The adjusting lead screw 2 is rotationally connected with the fixing plate 1 through a self-locking bearing, and the adjusting lead screw 2 is threadedly connected with the water blocking seat 3.

[0026] Preferably, a rubber sleeve 6 is sleeved between the surfaces of the water blocking seat 3 away from the turntable 5. A plugging airbag 4 is fixedly connected to one side of the water blocking seat 3 away from the turntable 5. The other side of the plugging airbag 4 is communicated with an exhaust pipe, and a solenoid valve is installed on the exhaust pipe.

[0027] Preferably, a plurality of rubber convex rings 7 are uniformly sleeved on the outer surface of the rubber sleeve 6 from left to right by injection molding. The top and bottom of one side of the fixing plate 1 are both fixedly connected with telescopic rods 8. One end of each of the two telescopic rods 8 passes through one side of the water blocking seat 3 and extends into the interior of the water blocking seat 3. The two telescopic rods 8 both have a limiting effect on the water blocking seat 3, and the water blocking seat 3 is fixedly connected with the rubber sleeve 6.

[0028] Preferably, gas delivery components 9 are fixedly connected above and below the water blocking seat 3 on one side of the fixing plate 1. The air outlet ends of the two gas delivery components 9 both pass through the water blocking seat 3 and extend into the interior of the plugging airbag 4.

[0029] Preferably, the gas delivery component 9 includes a mounting plate 91 and an air cavity 92. The mounting plate 91 is fixedly connected to one side of the fixing plate 1. An air pump 93 is fixedly connected to one side of the mounting plate 91. The air inlet end of the air pump 93 is communicated with an air inlet pipe 94. The air cavity 92 is opened between the two sides of the water blocking seat 3 and is located inside the water blocking seat 3. The air outlet end of the air pump 93 is communicated with an air outlet pipe 95. One end of the air outlet pipe 95 is communicated with a corrugated telescopic pipe 96. A delivery pipe 97 is communicated between one end of the corrugated telescopic pipe 96 and one end of the air cavity 92. The other end of the air cavity 92 is communicated with a connecting pipe 98. One end of the connecting pipe 98 passes through the water blocking seat 3, the rubber sleeve 6 and the plugging airbag 4 in sequence and extends into the interior of the plugging airbag 4.

[0030] Specifically, in the above solution, the water plugging seat 3 is fixedly connected to the connecting pipe 98, and the connecting pipe 98 is fixedly connected to the rubber sleeve 6.

[0031] Specifically, in the above solution, the connecting pipe 98 is fixedly connected to the plugging airbag 4 and is in communication with the plugging airbag 4.

[0032] During application, by rotating the turntable 5 clockwise, the adjusting lead screw 2 is driven to rotate. Since the water plugging seat 3 is limited by the two telescopic rods 8, when the adjusting lead screw 2 rotates clockwise, the water plugging seat 3 can be driven to move from right to left, and then the plugging airbag 4 can be inserted into the water pipe from right to left, and the water plugging seat 3 equipped with the rubber sleeve 6 is inserted into the water pipe. The water plugging seat 3 is frustum-shaped, so that the water plugging seat 3 can elastically clamp and seal pipes with different diameters through the rubber sleeve 6. And the rubber convex rings 7 can increase the frictional force between the rubber sleeve 6 and the inner wall of the external water pipe. Moreover, the shape formed by the multiple rubber convex rings 7 is frustum-shaped, which can be adjusted appropriately according to the inner diameter of the water pipe by the water plugging seat 3 for plugging, effectively improving the adaptation range for plugging and blocking water in municipal pipelines, saving the cost of municipal pipeline maintenance equipment. Then, start the air pumps 93 inside the two gas delivery components 9, extract external air through the air inlet pipe 94 and transport it to the air outlet pipe 95, transport the gas from the air outlet pipe 95 to the delivery pipe 97 through the corrugated expansion pipe 96, and open the solenoid valve on the delivery pipe 97 to transport the gas from the air cavity 92 to the connecting pipe 98. The gas is transported to the inside of the plugging airbag 4 through the connecting pipe 98. The plugging airbag 4 is made of rubber and can elastically change its volume with the amount of gas filled inside, so that it can be flexibly adjusted for plugging according to the inner diameter of the water pipe. The water pipe is double-blocked by the water plugging seat 3 and the plugging airbag 4, improving the water blocking effect of the pipe plugging and reducing the phenomenon of water leakage, improving the convenience of municipal pipeline maintenance work.

[0033] In this way, by rotating the turntable 5 to drive the adjusting lead screw 2 to rotate, the water plugging seat 3 and the plugging airbag 4 can be pushed to move into the municipal pipeline in sequence. The rubber sleeve 6 equipped with the rubber convex rings 7 is sleeved outside the water plugging seat 3, which can increase the frictional force between the water plugging seat 3 and the inner wall of the pipe, thus expanding the water pressure bearing range of the water plugging seat 3. And the water pipe is double-blocked by the water plugging seat 3 and the plugging airbag 4, improving the water blocking effect of the pipe plugging and reducing the phenomenon of water leakage, improving the convenience of municipal pipeline maintenance work.

[0034] In addition, since the water blocking seat 3 is frustum-shaped, the water blocking seat 3 can elastically clamp and seal pipes of different diameters through the rubber sleeve 6, and the rubber convex rings 7 can increase the frictional force between the rubber sleeve 6 and the inner wall of the external water pipe. Moreover, the shape formed by multiple rubber convex rings 7 is frustum-shaped, which can be adjusted and blocked appropriately according to the inner diameter of the water pipe along with the water blocking seat 3, effectively improving the adaptation range for blocking water in municipal pipelines and saving the cost of municipal pipeline maintenance equipment.
