Description

Technical Field

[0001] This utility model relates to the field of water-blocking device technology, and in particular to a water-blocking device for repairing drainage pipe networks. Background Technology

[0002] A drain pipe repair plug is a device used to temporarily or permanently block the flow of water in a drain pipe. These plugs are typically used during pipe repair, inspection, or replacement of pipe components to prevent sewage leakage into the environment or disruption of repair work. Currently, existing drain pipe repair methods usually employ ultraviolet curing to solidify resin at the damaged area of ​​the drain pipe, thus completing the repair. Before using this repair method, it is usually necessary to use a drain pipe repair plug to seal the upstream pipe at the damaged area of ​​the drain pipe.

[0003] Currently available drainage pipe network repair devices typically use plugs to block the drainage pipe network. However, the diameter of urban underground drainage pipe networks is generally large, making it difficult for traditional plugs to effectively block water in the drainage pipes.

[0004] Therefore, to address the problem that existing urban underground drainage pipe networks have large apertures and traditional plugs are ineffective at blocking water, a water-blocking device for drainage pipe network repair can be designed. This device consists of a rotating disc, a two-way threaded rod, a moving block, a connecting rod, a mounting box, a spring, and an arc-shaped clamping plate. When the rotating disc is rotated, the arc-shaped clamping plate, in conjunction with the spring, can center and fix the drainage pipe network, thus positioning the plug. Similarly, a rotating disc, a screw rod, a screw hole, a plug, and a sealing ring are also included. When the rotating disc is rotated, the plug moves towards the drainage pipe network, and the sealing ring, in conjunction with the plug, seals the drainage pipe network, thereby blocking water. Utility Model Content

[0005] In order to overcome the problem that the existing urban underground drainage pipe network has a large diameter and traditional plugs are difficult to use for blocking water.

[0006] The technical solution of this utility model is as follows: a water plug for repairing drainage pipe networks, including an installation box 1; a screw hole 1 is opened on the right side of the installation box 1, a screw rod 1 is threadedly connected inside the screw hole 1, a rotating disk 1 is fixedly installed at the right end of the screw rod 1, a plug is installed at the left end of the screw rod 1 through a bearing, an annular groove is opened on the left side of the plug, a sealing ring is installed inside the annular groove, a rotating disk 3 is installed at the front side of the installation box 1, a bidirectional threaded rod is fixedly installed at the rear side of the rotating disk 3, the other end of the bidirectional threaded rod is installed at the rear side inside the installation box 1 through a bearing, movable blocks are threadedly connected to the outer sides of both ends of the bidirectional threaded rod, a connecting rod 1 is fixedly installed at the top of the movable block, an installation box 2 is fixedly installed inside the connecting rod 1, a spring is fixedly installed at the end of the installation box 2 near the connecting rod 1, a limit plate is fixedly installed at the other end of the spring, a connecting rod 2 is fixedly installed inside the limit plate, and an arc-shaped clamping plate is fixedly installed through the installation box 2 at the other end of the connecting rod 2.

[0007] Preferably, when the operator rotates the rotating disk three, the rotating disk three drives the bidirectional threaded rod to rotate. The moving block, under the action of the bidirectional threaded rod, moves the arc-shaped clamping plate inward through the connecting rod one and the mounting box two. The arc-shaped clamping plates on both sides can clamp and fix the drainage pipe network. At this time, the operator continues to rotate the rotating disk three. The arc-shaped clamping plate, under the action of the drainage pipe network, pushes the limiting plate outward relative to the mounting box two through the connecting rod two. The spring is compressed, and the spring rebound force acts on the arc-shaped clamping plate. The arc-shaped clamping plates on both sides can firmly clamp the drainage pipe network, thereby completing the centered installation of the mounting box one, so that the position of the plug matches the drainage pipe network. Then, the operator rotates the rotating disk one, the rotating disk one drives the screw one to rotate. The screw one, under the action of the screw hole one, drives the plug to move to the left. The annular groove on the plug can then fit on the outside of the drainage pipe network. The sealing ring can then press against the drainage pipe network to seal the drainage pipe network, thereby achieving the function of blocking water.

[0008] Preferably, a limit block is fixedly installed at the bottom of the movable block, and a limit groove is opened at the bottom inside the mounting box. The limit block is set inside the limit groove, and the limit block and the limit groove are slidably connected. The opening of the limit groove facilitates the setting of the limit block. The limit block and the limit groove work together to limit the movable block, so that the movable block can move smoothly.

[0009] Preferably, a reinforcing rib is fixedly provided on the inner side of the connecting rod one, and the top of the reinforcing rib is fixedly provided on the bottom of the mounting box two. The reinforcing rib can enhance the structural strength of the connecting rod one and the mounting box two.

[0010] Preferably, a limiting rod 2 is fixedly installed at the lower right end of the plug, and the other end of the limiting rod 2 passes through the mounting box 1 and is located on the right side of the mounting box 1. The setting of the limiting rod 2 can limit the plug, so that it can move smoothly left and right.

[0011] Preferably, the top of the mounting box is provided with a screw hole 2, and the screw hole 2 is internally threaded to a screw rod 2. The screw hole 2 facilitates the setting of the screw rod 2. When the screw rod 2 rotates, the screw rod 2 can move up and down due to the action of the screw hole 2 thread.

[0012] Preferably, a rotating disk is fixedly installed at the upper end of the screw two, and an arc-shaped support plate is fixedly installed at the lower end of the screw two. When the operator rotates the rotating disk two, the rotating disk two can drive the screw two to rotate, and the screw two can then drive the arc-shaped support plate to move downward.

[0013] Preferably, a limiting rod is fixedly installed on the front side of the top of the arc-shaped support plate. The other end of the limiting rod passes through the mounting box and is located at the upper end of the mounting box. The limiting rod can limit the arc-shaped support plate, thereby enabling it to move up and down smoothly.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a rotating disk three, a double-threaded rod, a moving block, a connecting rod one, a mounting box two, a spring, and an arc-shaped clamping plate, the operator rotates the rotating disk three, which in turn drives the double-threaded rod to rotate. The moving blocks on both sides are driven by the thread of the double-threaded rod to move the arc-shaped clamping plate inward. The arc-shaped clamping plate, together with the spring, can clamp and fix the drainage pipe network in the center, thereby completing the positioning of the plug.

[0016] 2. By setting up a rotating disk, a screw, a screw hole, a plug, and a sealing ring, the operator rotates the rotating disk, which in turn drives the screw to rotate. The screw, through the screw hole, drives the plug to move towards the drainage network. The sealing ring then seals the drainage network, thereby blocking water flow. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-4This utility model provides an embodiment: a water plug for repairing drainage pipe networks, including a mounting box 1; a screw hole 2 is provided on the right side of the mounting box 1, and a screw rod 3 is threadedly connected inside the screw hole 2; a rotating disk 4 is fixedly installed at the right end of the screw rod 3; a plug 5 is installed at the left end of the screw rod 3 via a bearing; an annular groove 6 is provided on the left side of the plug 5, and a sealing ring 7 is provided inside the annular groove 6; a rotating disk 32 is provided on the front side of the mounting box 1; a bidirectional threaded rod 13 is fixedly installed on the rear side of the rotating disk 32; the other end of the bidirectional threaded rod 13 is connected to... The bearing is installed inside the rear side of mounting box 1. Moving blocks 14 are threaded to the outer sides of both ends of the bidirectional threaded rod 13. A connecting rod 15 is fixedly installed on the top of the moving block 14. Mounting box 2 16 is fixedly installed inside the connecting rod 15. A spring 17 is fixedly installed inside mounting box 2 16 near the end of the connecting rod 15. A limit plate 18 is fixedly installed at the other end of the spring 17. A connecting rod 2 19 is fixedly installed inside the limit plate 18. An arc-shaped clamping plate 20 is fixedly installed through mounting box 2 16. Rotating the rotating disk 12 causes the bidirectional threaded rod 13 to rotate. The moving block 14, acting on the thread of the bidirectional threaded rod 13, moves the arc-shaped clamping plate 20 inward via the connecting rod 15 and mounting box 26. The arc-shaped clamping plates 20 on both sides then clamp and fix the drainage pipe network. If the rotating disk 12 is continued to rotate, the arc-shaped clamping plate 20, acting on the drainage pipe network, pushes the limiting plate 18 outward relative to the mounting box 26 via the connecting rod 29. This compresses the spring 17, and the spring 17 rebounds. The reaction force acts on the arc-shaped clamping plate 20, which can securely clamp the drainage pipe network, thereby completing the centered installation of the installation box 1, so that the position of the plug 5 matches the drainage pipe network. Then, the operator rotates the rotating disk 4, which drives the screw 3 to rotate. The screw 3, under the action of the thread of the screw hole 2, can drive the plug 5 to move to the left. The annular groove 6 on the plug 5 can then fit on the outside of the drainage pipe network, and the sealing ring 7 can then press against the drainage pipe network to seal it, thereby blocking the water.

[0024] Please see Figures 2-4In this embodiment, a limiting block 22 is fixedly provided at the bottom of the moving block 14, and a limiting groove 23 is opened at the bottom inside the first mounting box 1. The limiting block 22 is located inside the limiting groove 23, and the limiting block 22 and the limiting groove 23 are slidably connected. A reinforcing rib 21 is fixedly provided on the inner side of the connecting rod 15, and the top of the reinforcing rib 21 is fixedly provided at the bottom of the second mounting box 16. A limiting rod 25 is fixedly provided at the lower right end of the plug 5, and the other end of the limiting rod 25 passes through the first mounting box 1 and is located on the right side of the first mounting box 1. The opening of the limiting groove 23 facilitates the setting of the limiting block 22. The limiting block 22, in conjunction with the limiting groove 23, can limit the moving block 14, so that the moving block 14 can move smoothly. The setting of the reinforcing rib 21 can strengthen the structural strength of the connecting rod 15 and the second mounting box 16. The setting of the limiting rod 25 can limit the plug 5, so that it can move smoothly left and right.

[0025] Please see Figures 2-3 In this embodiment, the top of the mounting box 1 is provided with a screw hole 8, and a screw rod 9 is threadedly connected inside the screw hole 8. A rotating disk 10 is fixedly installed at the upper end of the screw rod 9, and an arc-shaped support plate 11 is fixedly installed at the lower end of the screw rod 9. A limit rod 24 is fixedly installed on the front side of the top of the arc-shaped support plate 11. The other end of the limit rod 24 passes through the mounting box 1 and is located at the upper end of the mounting box 1. When the operator rotates the rotating disk 10, the rotating disk 10 can drive the screw rod 9 to rotate. The screw rod 9 can move up and down under the action of the screw hole 8, which can drive the arc-shaped support plate 11 to move up and down, and thus drive the mounting box 1 to move up and down. The operator can adjust the height of the mounting box 1 to match the horizontal position of the arc-shaped clamping plates 20 on both sides with the drainage pipe network, so as to facilitate the clamping and fixing of the arc-shaped clamping plates 20 in the subsequent process. The limit rod 24 can limit the arc-shaped support plate 11, so that it can move up and down smoothly.

[0026] During operation, the operator first places the installation box 1 on the drainage pipe network via the arc-shaped support plate 11. Then, the operator rotates the rotating disk 2 10, which drives the screw 2 9 to rotate. The screw 2 9, under the action of the threaded hole 2 8, moves up and down, thereby driving the arc-shaped support plate 11 to move up and down, and in turn, driving the installation box 1 to move up and down. The operator adjusts the height of the installation box 1 1 until the arc-shaped clamping plates 20 on both sides are aligned with the horizontal position of the drainage pipe network. Then, the operator rotates the rotating disk 3 12, which drives the bidirectional threaded rod 13 to rotate. The moving block 14, under the action of the bidirectional threaded rod 13, moves the arc-shaped clamping plate 20 inward through the connecting rod 1 15 and the installation box 2 16. The arc-shaped clamping plates 20 on both sides then clamp and secure the drainage pipe network. At this point, the operator continues to rotate the rotating disk 12. The arc-shaped clamping plate 20, under the action of the drainage pipe network, pushes the limiting plate 18 to move outward relative to the mounting box 16 through the connecting rod 19. The spring 17 is thus compressed, and the rebound force of the spring 17 acts on the arc-shaped clamping plate 20. The arc-shaped clamping plates 20 on both sides can then firmly clamp the drainage pipe network, thereby completing the centered installation of the mounting box 1, so that the position of the plug 5 matches that of the drainage pipe network. Subsequently, the operator rotates the rotating disk 4, which drives the screw 3 to rotate. The screw 3, under the action of the thread of the screw hole 2, drives the plug 5 to move to the left. The annular groove 6 on the plug 5 can then fit onto the outside of the drainage pipe network, and the sealing ring 7 can then press against the drainage pipe network to seal it, thereby blocking the water.

[0027] Through the above steps, by setting up a rotating disk 12, a two-way threaded rod 13, a moving block 14, a connecting rod 15, a mounting box 16, a spring 17, and an arc-shaped clamping plate 20, the operator rotates the rotating disk 12, and the arc-shaped clamping plate 20 works with the spring 17 to clamp and fix the drainage pipe network in the center, thus completing the positioning of the plug 5. By setting up a rotating disk 4, a screw 3, a screw hole 2, a plug 5, and a sealing ring 7, the operator rotates the rotating disk 4, and the plug 5 moves towards the drainage pipe network. The sealing ring 7 works with the plug 5 to seal the drainage pipe network, thereby blocking water and solving the problem that the existing urban underground drainage pipe network has a large aperture and traditional plugs are difficult to use for blocking water.
