As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0026] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, an embodiment of the utility model provides a reinforcement device for municipal drainage pipes, including a placement plate 1, a connecting plate 2 is fixedly installed on the surface of the placement plate 1, a bidirectional threaded rod 3 is rotatably connected to the inner side of the placement plate 1, a moving block 4 is slidably connected to the inner side of the placement plate 1, the top of the moving block 4 is hinged with a connecting plate 5 through a rotating shaft, the inner side of the connecting plate 5 is hinged with a connecting block 6 through a rotating shaft, a reinforcement sleeve plate 7 is fixedly installed on the top of the connecting block 6, ring plates 8 are fixedly installed at both ends of the reinforcement sleeve plate 7, a reducing pad 9 is fixedly installed on the side of the ring plate 8, a shrinkage groove 10 is provided on the inner side of the reducing pad 9, an opening and closing ring 11 is sleeved on the surface of the ring plate 8, an opening and closing nut 12 is threadedly connected to the surface of the ring plate 8, a handle 13 is fixedly installed on the surface of the opening and closing nut 12, and a connecting bolt 14 is provided on the inner side of the opening and closing nut 12.

[0028] In one embodiment, a plugboard 15 is fixedly mounted on the surface of the placement plate 1. An insertion slot 16 is defined on the inner side of the plugboard 15. An anchor post 17 is slidably connected to the inner side of the plugboard 15. A contact plate 18 is fixedly mounted on one end of the anchor post 17. A spring 19 is sleeved on the surface of the anchor post 17. An insertion rod 20 is inserted into the inner side of the plugboard 15. The insertion rod 20 is aligned with the insertion slot 16 and hammered into the inner side of the plugboard 15. At this time, when the plugboard 15 contacts the contact plate 18, the anchor post 17 can be driven to pop out from the inner side of the plugboard 15 and insert into the surrounding ground.

[0029] In one embodiment, the opening and closing ring 11 is screwed onto the surface of the ring plate 8. The screws of the opening and closing ring 11 are unscrewed, and then the opening of the opening and closing ring 11 is performed along the axis.

[0030] In one embodiment, the inner side of the moving block 4 is provided with a thread, which engages with the thread on the surface of the bidirectional threaded rod 3. The bidirectional threaded rod 3 is rotated and the two sets of moving blocks 4 are driven to slide in opposite directions along the placement plate 1 under the action of the thread.

[0031] In one embodiment, the ring plate 8 is provided with threads on its surface, which mesh with threads on the inner side of the nut 12. When the nut 12 is rotated and moved outward along the ring plate 8, the nut 12 pushes the closure ring 11 and causes it to slide along the variable diameter pad 9.

[0032] In one embodiment, one end of the spring 19 is fixedly mounted on the inner side of the insert plate 15, and the other end of the spring 19 is fixedly mounted on the side of the contact plate 18. When the insertion rod 20 is withdrawn from the inner side of the insert plate 15, the spring 19 drives the anchor post 17 to retract into the inner side of the insert plate 15.

[0033] In one embodiment, the top of the contact plate 18 is rounded. When the inserting plate 15 contacts the contact plate 18, the combined effect of the rounded corners and pressure can drive the anchoring column 17 to pop out from the inside of the inserting plate 15 and insert into the surrounding ground.

[0034] When the utility model is working: when working, first install the placement plate 1 between the ground, leave a suitable hole between the ground, then insert the plugging plate 15 into the hole, then align the plugging rod 20 with the insertion groove 16 and hammer it into the inner side of the plugging plate 15. At this time, during the contact between the plugging plate 15 and the contact plate 18, under the combined action of the fillet and pressure, the anchor column 17 can be driven to pop out from the inner side of the plugging plate 15 and inserted into the surrounding ground, thereby improving the anchoring firmness between the placement plate 1 and the ground. During this process, the spring 19 will be squeezed. When the plugging rod 20 is pulled out from the inner side of the plugging plate 15, the anchor column 17 will be driven to retract into the inner side of the plugging plate 15 under the action of the spring 19, making it easy to pull out. Then use fasteners to connect the connecting plate 2 to the ground, then rotate the bidirectional threaded rod 3 and drive the two sets of moving blocks 4 along the opposite direction of the placement plate 1 under the action of the thread. The screws 14 of the opening and closing ring 11 and the connecting bolt 14 of the opening and closing nut 12 are then unscrewed, and the reinforcing sleeve 7 is opened along the axis, and the drainage pipe is placed inside the reinforcing sleeve 7. The reinforcing sleeve 7 is then closed again, and the opening and closing ring 11 is sleeved on the surface of the ring plate 8 with the screws, and the connecting bolt 14 is used to engage the threaded connection of the opening and closing nut 12 with the surface of the ring plate 8. The opening and closing nut 12 is then rotated and moved outward along the ring plate 8. In this process, the opening and closing ring 11 will be pushed and made to slide along the variable diameter cushion 9. Under the action of pressure and the shrinkage groove 10, the variable diameter cushion 9 will be deformed and squeezed against the pipe, thereby improving the sealing and strengthening the pipe reinforcement strength.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
