Description

Technical Field

[0001] The utility model belongs to the technical field of pipelines, in particular to a detachable water conservancy pipeline. Background Art

[0002] The connection of water conservancy pipes is generally made by flanges. When the pipes are blocked by silt and gravel, the water conservancy pipes need to be dredged. It is troublesome to remove the many screws on the flanges. Therefore, we designed a detachable water conservancy pipe, which is connected by tightening, which is convenient for dismantling and improves the efficiency of pipe dredging. Utility Model Content

[0003] The utility model aims to provide a detachable water conservancy pipeline, which has the advantages of being connected by tightening and tightening, being easy to dismantle, and improving the efficiency of pipeline dredging, so as to solve the above-mentioned background technical problems.

[0004] The utility model solves the above-mentioned technical problem with a technical solution as follows: a detachable water conservancy pipeline, comprising four hanging pins fixed on the surface of one pipeline in an annular array and four fixed shafts fixed on the surface of another pipeline in an annular array, the fixed shaft being rotatably connected to a rotating block at one end away from the second pipeline, a threaded column being slidably connected to the inner cavity of the rotating block, a hanging block being fixedly connected to one end of the threaded column close to the first pipeline, a hanging groove matching the hanging pin being provided on one side of the hanging block, a hexagonal screw sleeve being rotatably connected to the side of the rotating block away from the hanging pin, and the hexagonal screw sleeve being threadedly connected to the surface of the threaded column.

[0005] Preferably, two symmetrical limiting grooves are provided on the surface of the threaded column, and the inner cavity of the rotating block is fixedly connected to two symmetrical limiting strips, and the limiting grooves are slidably connected to the surfaces of the limiting strips.

[0008] Preferably, the surface of the hook pin is provided with a plurality of anti-slip grooves.

[0009] 1. The beneficial effect of the utility model is as follows: the utility model connects the pipe one with the pipe two, and then rotates the rotating block so that the hanging groove on the hanging block is sleeved on the surface of the hanging pin, and then the hexagonal screw sleeve is operated to rotate. Because the thread drives the threaded column to move to the right, the hanging groove on the hanging block is firmly hooked on the surface of the hanging pin, thereby realizing the connection between the pipe one and the pipe two. When the pipe needs to be unblocked, it is only necessary to operate the hexagonal screw sleeve to move the threaded column to the left and turn the hanging block away from the surface of the hanging pin, thereby achieving the purpose of connecting by tightening and tightening, facilitating dismantling, and improving the efficiency of pipe unblocking.

[0010] 2. The utility model uses the positioning slot and the positioning block in coordination. When pipe one and pipe two are connected, the positioning block is inserted into the inner cavity of the positioning slot to achieve positioning between pipe one and pipe two to prevent pipe one and pipe two from being misaligned. The hanging pin and the hanging block are also positioned so that the hanging pin and the hanging block are located on the same horizontal plane, which is convenient for subsequent connection.

[0011] 3. The utility model uses a sealing ring in conjunction with a sealing groove. After the sealing ring is inserted into the inner cavity of the sealing groove, the connection between the first pipe and the second pipe can be sealed, thereby avoiding water seepage at the connection.

[0012] 4. The utility model uses the limiting strip and the limiting groove in coordination. When the threaded column moves, the limiting groove will slide on the surface of the limiting strip, thereby guiding and limiting the threaded column, thereby preventing the threaded column from rotating with the hexagonal screw sleeve.

[0020] Hereinafter, embodiments of the detachable water conservancy pipeline of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-4 A detachable water conservancy pipeline of an embodiment of the utility model is shown, which includes four hanging pins 3 fixed on the surface of pipeline 1 in an annular array and four fixed shafts 4 fixed on the surface of pipeline 2 in an annular array. Both ends of pipeline 1 close to the side of pipeline 2 are fixedly connected with positioning blocks 12, and both ends of pipeline 2 close to the side of pipeline 1 are provided with positioning slots 13 for inserting the positioning blocks 12. Through the cooperation of the positioning slots 13 and the positioning blocks 12, when pipeline 1 is docked with pipeline 2, the positioning blocks 12 are inserted into the inner cavity of the positioning slots 13 to realize positioning between pipeline 1 and pipeline 2, prevent pipeline 1 and pipeline 2 from being misaligned, and also position the hanging pins 3 and the hanging blocks 7 so that the hanging pins 3 and the hanging blocks 7 are located in the same horizontal plane, which is convenient for subsequent connection. A sealing ring 14 is fixedly connected to the side of pipeline 1 close to pipeline 2, and a sealing groove 15 is provided on the side of pipeline 2 close to pipeline 1 for inserting the sealing ring 14. Through the cooperation of the sealing ring 14 and the sealing groove 15, the sealing ring 1 After the shaft 4 is inserted into the inner cavity of the sealing groove 15, the connection between the pipe 1 and the pipe 2 can be sealed to avoid water seepage at the connection. The end of the fixed shaft 4 away from the pipe 2 is rotatably connected to the rotating block 5. The inner cavity of the rotating block 5 is slidably connected to the threaded column 6. The surface of the threaded column 6 is provided with two symmetrical limiting grooves 11. The inner cavity of the rotating block 5 is fixedly connected to two symmetrical limiting strips 10. The limiting grooves 11 are slidably connected to the surface of the limiting strips 10. The limiting strips 10 cooperate with the limiting grooves 11 to make the When the threaded column 6 moves, the limiting groove 11 will slide on the surface of the limiting strip 10, thereby guiding and limiting the threaded column 6, and preventing the threaded column 6 from rotating with the hexagonal screw sleeve 9. The end of the threaded column 6 close to the pipe 1 is fixedly connected to a hanging block 7, and a hanging groove 8 compatible with the hanging pin 3 is provided on one side of the hanging block 7. The side of the rotating block 5 away from the hanging pin 3 is rotatably connected to the hexagonal screw sleeve 9. The hexagonal screw sleeve 9 is threadedly connected to the surface of the threaded column 6, and the surface of the hanging pin 3 is provided with multiple anti-slip grooves.

[0022] Working principle: When the utility model is used, the user docks pipe 1 with pipe 2 2, during which the sealing ring 14 enters the inner cavity of the sealing groove 15, the positioning plug 12 enters the inner cavity of the positioning slot 13, and then rotates the rotating block 5 to make the hanging groove 8 on the hanging block 7 sleeve on the surface of the hanging pin 3, and then operates the hexagonal screw sleeve 9 to rotate, because the thread drives the threaded column 6 to move to the right, so that the hanging groove 8 on the hanging block 7 is firmly hooked on the surface of the hanging pin 3, and the anti-slip stripes on the surface of the hanging pin 3 effectively prevent the hanging pin 3 from slipping from the inner cavity of the hanging groove 8 due to insufficient friction, thereby realizing the connection between pipe 1 and pipe 2 2. When it is necessary to dredge the pipe, it is only necessary to operate the hexagonal screw sleeve 9 to make the threaded column 6 move to the left, turn the hanging block 7 away from the surface of the hanging pin 3, and then separate pipe 1 from pipe 2 2, thereby achieving the purpose of connecting by tightening and fastening, facilitating dismantling, and improving the efficiency of pipe dredging.

[0023] To sum up: the detachable water conservancy pipeline is connected by connecting pipeline 1 with pipeline 2, and then rotating the rotating block 5 so that the hanging groove 8 on the hanging block 7 is sleeved on the surface of the hanging pin 3, and then the hexagonal screw sleeve 9 is operated to rotate. The thread drives the threaded column 6 to move to the right, so that the hanging groove 8 on the hanging block 7 is firmly hooked on the surface of the hanging pin 3, thereby realizing the connection between pipeline 1 and pipeline 2. When the pipeline needs to be unblocked, it is only necessary to operate the hexagonal screw sleeve 9 to move the threaded column 6 to the left and turn the hanging block 7 away from the surface of the hanging pin 3, thereby achieving the purpose of connecting by tightening and tightening, facilitating dismantling, and improving the efficiency of pipeline unblocking.
