Description

Technical Field

[0001] The invention relates to the technical field of pre-buried pipe joints, in particular to a hydraulic pre-buried pipe joint capable of preventing sediment deposition. Background Art

[0002] At present, in people's daily life and industrial production, in order to achieve the rapid transportation of water resources, long pipes are used for connection to achieve the purpose of transportation. Since most pipes have a certain length, pipe connection devices are needed to connect them to increase the transportation distance, so they are widely used.

[0003] During use, the water will contain mud and sand, which can easily cause accumulation at the pipe joints. Manual cleaning is inconvenient, time-consuming and labor-intensive. It is difficult to remove debris from the pipe, which will affect the water quality for a long time and even cause transportation interruptions.

[0004] The existing technology cannot effectively clean the pipe connection device, and the pipe needs to be disassembled, which is time-consuming and labor-intensive. Especially at the bends in the pipe connection, the water flow rate slows down, which will cause more sediment to settle. How to clean the bends is a difficult problem in this field. Summary of the invention

[0005] The purpose of the invention is to solve the shortcomings of the prior art and to propose a hydraulic pre-buried pipe joint that can prevent sediment deposition.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A hydraulic pre-buried pipe joint capable of preventing sediment deposition, comprising a bend pipe connector, one side of which is provided with a regulating mechanism;

[0008] A connecting pipe fitting is sealed and fixed at the upper end of the elbow connector, a filter tube is penetrated in the connecting pipe fitting, a plurality of filter holes are evenly spaced on the filter tube, a flow limiting mechanism is provided on both sides of the filter tube, a round rod is provided on the regulating mechanism, the round rod is rotatably connected to the lower part of the elbow connector, an isolation disk is fixedly sleeved on the round rod, and the diameter of the isolation disk is the same as the inner diameter of the elbow connector.

[0009] Compared with the prior art, the present application can realize the rapid connection and disassembly of the corresponding components, and can effectively ensure the sealing of the connection between the corresponding components, so as to ensure the sealing effect inside the elbow connector when not in use, and can cut off the water flow as needed during use, and disassemble and clean it to better ensure the penetration performance of the elbow connector and facilitate the flow of water.

[0010] Preferably, a sealing disk is provided at the upper end of the connecting pipe fitting, a threaded column is fixed at the lower end of the sealing disk, the threaded column is threadedly sleeved in the connecting pipe fitting, a telescopic rod is fixed at the lower end of the threaded column, a rubber sealing gasket is fixed at the lower end of the telescopic rod, a compression spring is sleeved on the telescopic rod, the lower end of the compression spring is fixed to the upper end of the rubber sealing gasket, the upper end of the compression spring is fixed to the lower end of the threaded column, the rubber sealing gasket is in contact with the upper end of the filter tube, and rubber pads are fixed at the top and bottom of the filter tube.

[0011] Furthermore, the filter tube can be squeezed by the telescopic rod and the compression spring, and the sealing effect of the filter tube installation can be ensured by the rubber pad, ensuring that water can only be discharged through the filter tube, so that sediment can be retained through the filter tube.

[0012] Preferably, a nut is fixed to the upper end of the sealing disk, and a sealing ring is provided at the lower end of the sealing disk. The sealing ring is sleeved on the threaded column, and the sealing ring abuts against the upper end of the connecting pipe.

[0013] Furthermore, the sealing ring can achieve sealing and avoid leakage.

[0014] Preferably, the limiting flow mechanism comprises two square-mouthed fixed disks arranged on both sides of the filter tube, the two square-mouthed fixed disks are both sealed and installed in the elbow connector, and the filter tube is located between the two square-mouthed fixed disks.

[0015] Furthermore, the square-mouthed fixed plate adopts a structure similar to a copper coin, and the square holes therein can facilitate water flow. The square holes correspond to the filter tubes, allowing quicksand to enter the filter tubes and be retained by the filter tubes. When disassembling, the inside of the elbow connector can be cleaned by taking and placing the filter tubes.

[0016] Preferably, two sealing rings are arranged at both ends of the elbow connector, two annular grooves are opened at both ends of the elbow connector, and four sealing rings are respectively arranged in the four annular grooves.

[0017] Furthermore, through the cooperation of the annular groove and the sealing ring, the sealing effect in the elbow connector can be effectively ensured when not connected.

[0018] Preferably, the regulating mechanism includes a sealing cover detachably connected to one side of the elbow connector, a threaded rod is screwed on the upper end of the sealing cover, a square frame is rotatably sleeved on the lower end of the threaded rod, the square frame is slidably installed on one side of the elbow connector, a resistance shaft is abutted inside the square frame, one end of the resistance shaft is rotatably sleeved on a second sealing disk, and one end of the round rod passes through the elbow connector and is fixed on one side of the second sealing disk.

The lifting and lowering of the square frame can cause the interference shaft to drive the second sealing disk to rotate. As the second sealing disk rotates, the isolation disk can be rotated to effectively ensure the sealing effect in the elbow connector when it is not connected. It can also effectively cut off the water flow during cleaning, thereby facilitating cleaning operations inside the elbow connector.

[0020] Preferably, two connecting plates are fixed to one side of the sealing cover, bolts are passed through the two connecting plates, and the bolts are screwed into the elbow connector.

[0021] Furthermore, the sealing cover and the elbow connector can be firmly connected by bolts, and a sealing gasket is also provided on the side of the sealing cover facing the elbow connector, which can effectively ensure the sealing of the connection between the sealing cover and the elbow connector and avoid leakage.

[0022] Preferably, a sealing gasket is sleeved on the upper end of the threaded rod, and the sealing gasket is located at the upper end of the sealing cover.

[0023] Furthermore, by rotating the threaded rod, the upper end of the threaded rod and the sealing cover can squeeze the sealing gasket, which can cause the sealing gasket to deform, so as to effectively perform the sealing operation.

[0024] Preferably, a draw cord is commonly fixed to two sealing rings located on the same side.

[0025] Furthermore, the two sealing rings on the same side can be moved synchronously by the action of the pull rope, so that the elbow connector can be quickly connected and connected to an external pipeline.

[0026] The beneficial effects of the present invention are:

[0027] 1. The filter tube can be squeezed by the telescopic rod and the compression spring, and the sealing effect of the filter tube installation can be ensured by the rubber pad, ensuring that the water flow can only be discharged through the filter tube, so as to intercept the sediment through the filter tube; the sealing operation can be achieved by the sealing ring to avoid leakage; the cooperation of the annular groove and the sealing ring can effectively ensure the sealing effect in the elbow connector when it is not connected;

[0028] 2. The square-mouthed fixed plate adopts a structure similar to a copper coin. The square hole inside it can facilitate water flow. The square hole corresponds to the filter tube, which can allow quicksand to enter the filter tube and be intercepted by the filter tube. When disassembling, the inside of the elbow connector can be cleaned by taking and placing the filter tube;

[0029] 3. By rotating the threaded rod and adjusting the rotation direction of the threaded rod, the square frame can be stably raised and lowered. The lifting and lowering of the square frame can cause the interference shaft to drive the second sealing disk to rotate. As the second sealing disk rotates, the isolation disk can be rotated to effectively ensure the sealing effect in the elbow connector when it is not connected. It can also effectively cut off the water flow during cleaning, making it easier to clean the elbow connector. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Reference Figure 1-5A water conservancy pre-buried pipe joint capable of preventing sediment deposition comprises a bend pipe connector 1, one side of which is provided with a regulating mechanism; the regulating mechanism comprises a sealing cover 20 detachably connected to one side of the bend pipe connector 1, a threaded rod 19 is screwed on the upper end of the sealing cover 20, a square frame 23 is rotatably sleeved on the lower end of the threaded rod 19, the square frame 23 is slidably mounted on one side of the bend pipe connector 1, a resisting shaft 24 is abutted in the square frame 23, and a second sealing disk 17 is rotatably sleeved on one end of the resisting shaft 24. One end of the round rod 16 passes through the elbow connector 1 and is fixed on one side of the second sealing disk 17. By rotating the threaded rod 19 and controlling the rotation direction of the threaded rod 19, the square frame 23 can push the interference shaft 24 to rise and fall. At the same time, the interference shaft 24 will move in the square frame 23 and will also drive the second sealing disk 17 to rotate. The rotation of the second sealing disk 17 can drive the round rod 16 to rotate, and the rotation of the round rod 16 can cause the isolation disk 15 to rotate, which can control whether the elbow connector 1 is closed.

[0038] Reference Figure 1-5 , a connecting pipe fitting 2 is sealed and fixed at the upper end of the elbow connector 1, a filter tube 12 is penetrated in the connecting pipe fitting 2, a plurality of filter holes 11 are arranged at equal intervals on the filter tube 12, and a limiting flow mechanism is arranged on both sides of the filter tube 12, and a round rod 16 is arranged on the regulating mechanism, and the round rod 16 is rotatably connected to the lower part of the elbow connector 1, and an isolation disk 15 is fixedly sleeved on the round rod 16, and the diameter of the isolation disk 15 is the same as the inner diameter of the elbow connector 1. The regulating mechanism can drive the isolation disk 15 to rotate through the round rod 16. After the assembly is completed and used for a certain period of time, when cleaning is required, the isolation disk 15 and the round rod 16 can be driven to rotate, so that the isolation disk 15 can seal the elbow connector 1, which is convenient for subsequent cleaning operations.

[0039] Reference Figure 1 , 2 , 3, 5, a sealing disk 3 is provided at the upper end of the connecting pipe fitting 2, a threaded column 5 is fixed at the lower end of the sealing disk 3, the threaded column 5 is threadedly sleeved in the connecting pipe fitting 2, a telescopic rod 7 is fixed at the lower end of the threaded column 5, a rubber sealing gasket 9 is fixed at the lower end of the telescopic rod 7, a compression spring 8 is sleeved on the telescopic rod 7, the lower end of the compression spring 8 is fixed to the upper end of the rubber sealing gasket 9, the upper end of the compression spring 8 is fixed to the lower end of the threaded column 5, the rubber sealing gasket 9 is in contact with the upper end of the filter tube 12, and rubber pads 10 are fixed at the top and bottom of the filter tube 12. The first sealing disk 3 is driven to rotate by the nut 4 to make the threaded column 5 and the connecting pipe fitting 2 cooperate, so that the threaded column 5 can push the compression spring 8 and the telescopic rod 7 so that the rubber sealing gasket 9 pushes the filter tube 12 down. At the same time, through the cooperation of the telescopic rod 7 and the compression spring 8, it can adapt to connecting pipe fittings 2 and elbow connectors 1 of different specifications to perform sealing operations, ensuring that the filter tube 12 corresponds to the square-mouth fixed disk 13.

[0040] Reference Figure 2 , 5 A nut 4 is fixed to the upper end of the sealing disk 3, and a sealing ring 6 is provided at the lower end of the sealing disk 3.

The two square-mouthed fixed disks 13 are both sealed and installed in the elbow connector 1. The filter tube 12 is located between the two square-mouthed fixed disks 13. The square-mouthed fixed disks 13 are similar to copper coin structures, and an opening is provided in the middle thereof to facilitate the flow of water. At the same time, the edges of the square-mouthed fixed disks 13 are sealed and fixedly connected to the inside of the elbow connector 1, so that water can only flow from the openings, and the water can impact the filter tube 12, so that mud and sand enter the filter tube 12. The water can be discharged through the filter holes 11, and the mud and sand are retained, so that the internal mud and sand and some mud and sand blocked on one side of the square-mouthed fixed disks 13 can be removed by removing the filter tube 12, thereby improving the standing efficiency.

The pull rope 25 can drive the two sealing rings 14 to move out of the elbow connector 1, so as to ensure that the elbow connector 1 is unobstructed before connection. At the same time, the sealing rings 14 cooperate with the annular grooves to effectively perform sealing operations.

[0043] Reference Figure 2 Two connecting plates 21 are fixed to one side of the sealing cover 20, and bolts 22 are penetrated through the two connecting plates 21. The bolts 22 are screwed into the elbow connector 1. Rotating the bolts 22 can make the connecting plates 21 drive the sealing cover 20 so that the sealing cover 20 fully contacts the elbow connector 1.

[0046] By driving the first sealing disk 3 to rotate by the nut 4, the threaded column 5 and the connecting pipe fitting 2 can be matched, and the threaded column 5 can push the compression spring 8 and the telescopic rod 7 so that the rubber sealing gasket 9 pushes the filter tube 12 to descend. At the same time, through the cooperation of the telescopic rod 7 and the compression spring 8, it is possible to adapt to the connecting pipe fittings 2 and the elbow connector 1 of different specifications to perform sealing operations, ensuring that the filter tube 12 and the square-mouth fixed disk 13 correspond to each other. After the filter tube 12 is disassembled and taken out, it is convenient to clean the mud and sand inside it and the mud and sand on one side of the blocked square-mouth fixed disk 13, thereby improving the cleaning efficiency and quality.
