Description

Technical Field

[0001] This utility model relates to the field of sewage pipeline technology, specifically to a partial maintenance and repair structure for sewage pipelines. Background Technology

[0002] Drainage engineering refers to projects that collect and discharge domestic sewage, various wastewaters from industrial processes, excess surface water, and groundwater (lowering the groundwater level). Sewage pipelines, responsible for discharging domestic sewage and industrial wastewater, are a crucial component of drainage engineering. The necessity of sewage pipeline network dredging and inspection: A sewage pipeline network is a complex system; a problem or damage in one area can cause a chain reaction, affecting the drainage capacity of the entire system. To maximize drainage capacity and extend pipeline lifespan, it is essential to establish comprehensive pipeline inspection and evaluation methods and scientific maintenance techniques for regular inspection, evaluation, dredging, and repair.

[0003] Most existing ordinary sewage pipes are formed by connecting multiple pipes end to end. When the pipes are inspected, it is necessary to disassemble the pipe joints and disassemble the pipes individually for inspection. This is inefficient and inconvenient for installation after the inspection is completed. Overall, it is not conducive to the maintenance of the pipes.

[0004] For example, the public document with application number 202321804189.0 discloses a partial maintenance and repair structure for sewage pipelines. This utility model facilitates quick pipeline repair by operators. However, in this partial maintenance and repair structure for sewage pipelines, after the inspection port is opened, the sealing cover of the inspection port is separated from the pipeline. That is, the cover needs to be removed and placed separately. The disassembled cover not only occupies the space for maintenance and repair, but also requires manual handling and alignment after the repair is completed to align the cover with the inspection port before reinstallation. This is not conducive to the storage of the cover and the sealing installation after the repair is completed. If there is a slight difference in alignment, gaps may easily appear in the inspection port, which may lead to sewage leakage during subsequent use.

[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a partial maintenance and repair structure for sewage pipelines. Utility Model Content

[0006] The purpose of this utility model is to provide a partial maintenance and repair structure for sewage pipelines to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a partial maintenance and repair structure for sewage pipes, comprising a pipe body, wherein a sliding groove is provided on the right side of the surface of the pipe body in an up-and-down distribution, a slider is slidably disposed on the inner surface of the sliding groove, the front end of the slider is fixedly connected to the same movable frame, a crossbeam is fixedly installed in the middle of the inner side of the movable frame, a lead screw is spirally connected through the middle of the surface of the crossbeam, a handwheel is fixedly installed at the front end of the lead screw, and a cover plate is rotatably connected to the rear end of the lead screw.

[0008] Preferably, the slider and the groove are configured as a matching "T" shape, the movable frame slides against the surface of the pipe body, and the cover plate slides against the inner surface of the movable frame.

[0009] Preferably, an inspection port is provided in the middle of the surface of the main body of the pipe, and an flared groove is provided around the inspection port on the surface of the main body of the pipe.

[0010] Preferably, the shape of the flared recess matches the shape of the inspection port, and a sealing gasket is fixedly installed on the rear edge of the cover plate.

[0011] Preferably, a spring is fixedly installed on the front side of the handwheel surface, and a locking pin is fixedly connected to the front end of the spring.

[0012] Preferably, the rear rod of the locking pin is located inside the spring, and the rear end of the locking pin slides through the handwheel.

[0013] Preferably, a positioning hole is provided on the surface of the cross frame on the left side of the lead screw penetration part, and the diameter of the positioning hole matches the diameter of the locking pin.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the design of a sliding groove, a slider, a movable frame, a crossbar, a lead screw, a handwheel, and a cover plate, enables more convenient and quick opening of the inspection port. Furthermore, the cover plate and the movable frame are integrated into the surface of the pipeline body, so that the cover plate does not need to be removed and placed separately after opening, avoiding the occupation of construction space after disassembly and storage. Moreover, the restoration and installation of the cover plate after maintenance is also extremely convenient, without the need for manual handling and alignment of the cover plate, thereby greatly improving the convenience of pipeline body maintenance.

[0016] 2. By incorporating a flared groove, spring, locking pin, positioning hole, and sealing gasket, this utility model greatly enhances the sealing capability of the cover plate against the main body of the pipeline when the cover plate is closed, effectively preventing sewage leakage through the inspection port. At the same time, it can fix the screw, greatly improving the stability of the cover plate after it is closed and preventing the screw from being affected by external forces and causing it to rotate and open the cover plate again.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a partial maintenance and repair structure for a sewage pipeline includes a pipeline body 1. A groove 2 is provided on the right side of the pipeline body 1 in an up-and-down distribution. A slider 3 is slidably arranged on the inner surface of the groove 2. The front end of the slider 3 is fixedly connected to the same movable frame 4. A crossbeam 5 is fixedly installed in the middle of the inner side of the movable frame 4. A screw 6 is spirally connected through the middle of the surface of the crossbeam 5. A handwheel 7 is fixedly installed at the front end of the screw 6. A cover plate 8 is rotatably connected to the rear end of the screw 6.

[0024] By adopting the above technical solution, when inspecting the pipeline, turning the handwheel 7 drives the screw 6 to rotate. The screw 6 and the cross frame 5 gradually move outward through the thread, thereby pulling the cover plate 8 to move forward gradually until the cover plate 8 is moved out of the inspection port 9 and stored inside the movable frame 4. Then, the movable frame 4 can be pushed to the right, so that the movable frame 4 slides to the right along the slide groove 2 using the slider 3, and moves the cover plate 8 to the right at the same time, thus opening the inspection port 9.

[0025] After maintenance is completed, push the movable frame 4 to the left until the slider 3 slides to the leftmost limit of the slide groove 2. At this time, it can be ensured that the movable frame 4 carrying the cover plate 8 is facing the maintenance port 9. Rotate the handwheel 7 and the lead screw 6 in the opposite direction to push the cover plate 8 into the maintenance port 9 for sealing.

[0026] Furthermore, the slider 3 and the groove 2 are set to match each other in a "T" shape, the movable frame 4 slides against the surface of the pipe body 1, and the cover plate 8 is located on the inner surface of the movable frame 4 and slides against it.

[0027] By adopting the above technical solution, the "T"-shaped groove 2 and slider 3 can prevent the movable frame 4 from falling off during sliding.

[0028] Furthermore, an inspection port 9 is provided in the middle of the surface of the main body of the pipeline 1, and a flared groove 10 is provided around the inspection port 9 on the surface of the main body of the pipeline 1.

[0029] The flared recess 10 is matched with the shape of the inspection port 9 and the cover plate 8, and a sealing gasket 14 is fixedly installed on the rear edge of the surface of the cover plate 8.

[0030] By adopting the above technical solution, the flared groove 10 increases the sinking range of the edge of the inspection port 9, thereby expanding the contact surface between the inspection port 9 and the cover plate 8 during installation. The gap is changed from being closed by insertion to being closed by the plate body. With the sealing gasket 14 attached at this edge, the sealing ability of the cover plate 8 to the main body of the pipeline 1 when closing the inspection port 9 can be greatly improved.

[0031] Furthermore, a spring 11 is fixedly installed on the front side of the handwheel 7, and a locking pin 12 is fixedly connected to the front end of the spring 11.

[0032] By adopting the above technical solution, the spring 11 provides a pulling force for the locking pin 12 to move backward.

[0033] Furthermore, the rear rod of the locking pin 12 is located inside the spring 11, and the rear end of the locking pin 12 slides through the handwheel 7; a positioning hole 13 is provided on the left side of the through part of the lead screw 6 on the surface of the crossbar 5, and the diameter of the positioning hole 13 matches the diameter of the locking pin 12.

[0034] By adopting the above technical solution, since the maximum insertion depth of the cover plate 8 from the inspection port 9 remains unchanged, and the length that the screw 6 can be turned and pushed also remains unchanged, after the handwheel 7 rotates the screw 6 to push the cover plate 8 to close the inspection port 9, the locking pin 12 carried by the handwheel 7 will definitely be at the same point, that is, the point opposite to the positioning hole 13. At this time, under the action of the spring 11, the locking pin 12 is inserted into the positioning hole 13, and the handwheel 7 can be fixed.

[0035] Working principle: When using this partial maintenance and repair structure for the sewage pipe, firstly, during pipe repair, pull the locking pin 12 to move it out of the positioning hole 13, then turn the handwheel 7 to drive the screw 6 to rotate. The screw 6 and the crossbar 5 gradually move outwards using the threaded groove, thereby pulling the cover plate 8 forward until the cover plate 8 moves out of the inspection port 9 and is stored inside the movable frame 4. Then, push the movable frame 4 to the right, so that the movable frame 4 slides to the right along the slide groove 2 using the slider 3, and moves the cover plate 8 to the right simultaneously, thus opening the inspection port 9. Personnel can then enter the pipe body 1 through the inspection port 9 to perform maintenance work on the pipe body 1. After the maintenance is completed, push the movable frame 4 to the left until the slider 3 slides to the leftmost limit of the slide groove 2. At this time, it can be ensured that the movable frame 4 carrying the cover plate 8 is facing the inspection port 9. Turn the handwheel 7 and the screw 6 in the opposite direction to push the cover plate 8 into the inspection port 9 for closure. During closure, the flared groove 10... By increasing the downward range of the edge of the inspection port 9, the contact surface between the inspection port 9 and the cover plate 8 during installation is expanded. The gap is changed from insertion and closure to a plate-body sealing. With the sealing gasket 14 attached at this edge, the sealing ability of the cover plate 8 to the main body of the pipeline 1 when closing the inspection port 9 is greatly improved, and sewage leakage through the inspection port 9 is fully prevented. After the cover plate 8 is completely sealed, since the maximum insertion depth of the cover plate 8 from the inspection port 9 remains unchanged, the length that the screw 6 can rotate and push also remains unchanged. Therefore, after the handwheel 7 rotates the screw 6 to push the cover plate 8 to close the inspection port 9, the locking pin 12 carried by the handwheel 7 will be at the same point, that is, the point opposite to the positioning hole 13. At this time, under the action of the spring 11, the locking pin 12 is inserted into the positioning hole 13, which can fix the handwheel 7. The handwheel 7 cannot rotate, so the screw 6 cannot rotate again, thus locking the position of the cover plate 8. This is the working principle of the partial maintenance and repair structure of the sewage pipeline.
