[0023] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0024] REFERENCE Figures 1-5A manhole for drainage pipe networks includes a manhole body 1. Multiple outer shells 3 are arranged in a vertical array on one inner wall of the manhole body 1, and each outer shell 3 has a slot on one side. One outer shell 3 is fitted with a locking block 4 within the slot. A safety rope 6 is fixedly connected to one side of the locking block 4, and a safety belt 7 is fixedly connected to the side of the safety rope 6 away from the locking block 4. A positioning component is provided on the top of each of the outer shells 3. Multiple handles 2 are fixedly installed in a vertical array on the inner wall of the manhole body 1 away from the outer shells 3. Specifically, by grasping the pull block 12 and pulling upwards, a spring 11 is pulled. The bottom end of the pull rod 10 is separated from the slot and socket to release the positioning of the locking block 4. By pulling the locking block 4 out of the outer casing 3 and engaging it with other parts of the outer casing 3, the locking block 4 can drive the safety rope 6 and safety belt 7 to lower personnel to other areas. This facilitates inspection work at different depths within the well body 1, preventing accidental falls during inspection operations. Personnel can easily adjust the connection between the locking block 4 and the outer casing 3 to control the length of the safety rope 6 and safety belt 7, ensuring stable support and protection during descent or ascent. This design effectively prevents the risk of accidental falls during inspection operations, improving operational safety and the practicality of the inspection well.

[0025] Furthermore, sliders 5 are fixedly connected to the top and bottom of the card block 4. Multiple outer shells 3 are provided with grooves that are adapted to the sliders 5 at the top and bottom of the card slot. Specifically, through the setting of sliders 5 and grooves, and the precise matching design of sliders 5 and grooves, the card block 4 can easily and accurately slide into the card slot inside the outer shell 3 without a complicated alignment process, which greatly improves the assembly efficiency. The sliding restriction of sliders 5 in the groove effectively prevents the card block 4 from moving laterally or longitudinally in the card slot, thereby enhancing the stability of the entire structure.

[0026] Furthermore, the outer walls of multiple outer shells 3 on the side away from the locking block 4 are fixedly connected to the adjacent inner walls of the well body 1, and each of the outer shells 3 has a round hole on its top. One of the sliders 5 has a socket on its top that communicates with the insertion hole, and the locking block 4 has a slot on its top that matches the insertion hole. Specifically, through the arrangement of round holes, insertion holes, and slots, by creating round holes on the top of the outer shells 3 and insertion holes on the top of the sliders 5, combined with slots on the locking blocks 4, this design allows the pull rod 10 to easily pass through the round holes from the outside, enter the insertion holes, and finally insert into the slots, achieving a secure fixation between the locking block 4, the slider 5, and the adjacent outer shells 3. This installation method is not only simple and quick but also facilitates personnel operation in installing and removing the locking block 4 from different outer shells 3, ensuring that the pull rod 10 can form a stable locking state during insertion, preventing safety hazards caused by loose connections. This design is particularly important for equipment that needs to withstand high loads or high-risk operating conditions, ensuring the safety of the equipment and operators.

[0027] Furthermore, the positioning component includes a mounting shell 8 disposed on the top of the outer casing 3. The bottom of the mounting shell 8 is open, and the bottom surface of the mounting shell 8 is fixedly connected to the top of the outer casing 3. A limiting plate 9 is provided inside the mounting shell 8, and a pull rod 10 is sleeved inside the limiting plate 9. The bottom end of the pull rod 10 is inserted into a socket and slot through a round hole, and the top end of the pull rod 10 is fixedly connected to a pull block 12 through the top of the mounting shell 8. Specifically, the pull block 12 allows personnel to easily grasp the pull block 12 and pull the pull rod 10 upwards, greatly improving the ease of operation. Simply grasping the pull block 12 and pulling upwards easily drives the pull rod 10 to slide within the limiting plate 9, thereby separating the locking block 4 from the outer casing 3. This intuitive and labor-saving operation method reduces the complexity and time cost of the disassembly process, requiring no additional tools or complicated operating steps.

[0028] Furthermore, the positioning component also includes a spring 11 disposed within the mounting housing 8. The interior of the spring 11 is fitted onto the exterior of the pull rod 10. The two ends of the spring 11 are fixedly connected to the top of the limiting plate 9 and the top of the inner wall of the mounting housing 8, respectively. Specifically, by holding the pull block 12 and pulling the spring 11 upwards, the bottom end of the pull rod 10 is separated from the slot and the insertion hole, releasing the positioning of the locking block 4. By pulling the locking block 4 out of the housing 3 and engaging it with other housings in the housing 3, the locking block 4 can drive the safety rope 6 and the safety belt 7 to lower the personnel to other areas, facilitating inspection work at different depths within the well body 1 and preventing accidental falls during inspection work. When the appropriate position is reached, the locking block 4 is engaged with the slot, and then the pull block 12 is released, causing the spring 11 to elastically return and drive the pull rod 10 back into the insertion hole and slot, thus completing the loading and unloading positioning. When working inside the well body 1, the personnel need to frequently adjust their position to inspect areas at different depths. Through the combined design of spring 11 and pull rod 10, personnel can easily adjust the connection between the locking block 4 and the outer casing 3, thereby controlling the length of the safety rope 6 and safety belt 7, ensuring stable support and protection during descent or ascent. This design effectively prevents the risk of accidental falls during inspection work, improving operational safety. The spring 11 automatically pushes the pull rod 10 back to its original position when the personnel release the pull block 12, achieving automatic reset. This design reduces the need for users to manually reset the pull rod 10, improving operational smoothness and efficiency. Simultaneously, the automatic reset function ensures that the pull rod 10 remains in a stable position when not needed, avoiding safety hazards caused by improper position of the pull rod 10.

[0029] Furthermore, each of the multiple mounting shells 8 has a limiting groove on one side of its top, and each of the multiple pull blocks 12 has a circular groove on one side of its bottom. The top of the mounting shell 8 has a limiting block 14 that matches the limiting groove. A rod 13 that matches the circular groove is fixedly connected to the top of the limiting block 14. Specifically, through the setting of the limiting block 14 and the rod 13, when a person pulls the pull block 12 upwards, the limiting block 14 in the limiting groove moves the rod 13 to directly below the circular groove. When the pull block 12 is released and returns to its original position, the rod 13 automatically inserts into the circular groove, precisely positioning and fixing the pull block 12. This allows personnel to free their hands and focus more on the loading and unloading operations between the locking block 4 and the shell 3, eliminating the need for continuous manual pulling of the pull block 12 and further improving operational convenience.

[0030] In summary:

[0031] By gripping the pull block 12 and pulling the spring 11 upwards, the bottom end of the pull rod 10 separates from the slot and socket, releasing the positioning of the locking block 4. By pulling the locking block 4 out of the outer casing 3 and engaging it with other parts of the outer casing 3, the locking block 4 can drive the safety rope 6 and safety belt 7, allowing personnel to descend to other areas. This facilitates inspection work at different depths within the well body 1, preventing accidental falls during inspection. Upon reaching the appropriate position, the locking block 4 engages with the slot, and then the pull block 12 is released, causing the spring 11 to elastically return and drive the pull rod 10 back into the socket and slot, thus completing the loading, unloading, and positioning. When working inside the well body 1, personnel need to frequently adjust their position to inspect areas at different depths. Through the combined design of the spring 11 and pull rod 10, personnel can easily adjust the connection between the locking block 4 and the outer casing 3, thereby controlling the length of the safety rope 6 and safety belt 7, ensuring stable support and protection during descent or ascent. This design effectively prevents the risk of accidental falls during inspection work, improving operational safety and the practicality of the inspection well.
