Description

Technical Field

[0001] This utility model relates to the field of maintenance well technology, specifically a prefabricated maintenance well for pre-embedded communication pipelines. Background Technology

[0002] Prefabricated communication pipeline pre-embedded inspection wells are a key component of urban communication infrastructure, providing necessary access and space for the laying and maintenance of communication cables. Through their robust structure and waterproof and corrosion-resistant properties, inspection wells effectively protect the safe operation of communication cables, ensuring the stability and reliability of communication services. Through the inspection wells, workers can easily enter the pipeline to inspect, unclog, repair, or replace damaged parts, thereby ensuring the normal operation of the communication pipeline system.

[0003] With the rapid development of modern urban construction, the requirements for communication pipeline systems are also increasing. Prefabricated maintenance manholes, with their excellent design, outstanding performance and convenient maintenance, have adapted to the needs of modern urban construction and provided new ideas and solutions for the development of urban infrastructure. However, in the current actual use, inconvenient installation and disassembly can affect the overall project progress and may lead to project delays. If the maintenance manhole components are damaged and difficult to disassemble and replace, the entire maintenance manhole may be scrapped, increasing replacement costs. Utility Model Content

[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] Please see Figures 1-4 As shown, a prefabricated communication pipeline pre-embedded maintenance well includes a well body 1 and a well cover 2, which are installed on the top of the well body 1. First mounting rings 3 are fixed on both sides of the well body 1.

[0024] The manhole cover 2 is designed to protect the pipes inside the manhole body 1. The first mounting ring 3 is designed to guide the pipes during installation, thus facilitating the installation of the pipes.

[0025] Limiting block 4 is fixed to the outside of manhole cover 2, and fixing block 5 is fixed to the outside of manhole body 1.

[0026] The limiting block 4 can be used in conjunction with the limiting frame 8 to facilitate the installation and removal of the manhole cover 2. The setting of the fixing block 5 facilitates the installation of the fixing column 6.

[0027] A fixed column 6 is fixed to the inner wall of the fixed block 5. A first spring 7 is fixed to one end of the fixed column 6. A limit frame 8 is slidably connected to the inner wall of the fixed column 6. A limit rod 9 is fixed to the outer side of the limit frame 8, and the outer side of the limit rod 9 is slidably connected to the inner wall of the fixed column 6.

[0028] During installation, the manhole cover 2 moves the fixing block 5. At this time, the fixing block 5 and the limiting frame 8 come into contact. Since the contact surface between the fixing block 5 and the limiting frame 8 is inclined, the limiting frame 8 will not be stuck but will be squeezed. At this time, the limiting frame 8 slides on the inner wall of the fixing column 6 and compresses the first spring 7 until the fixing block 5 falls below the limiting frame 8. At this time, the compressed first spring 7 pushes out of the limiting frame 8, thereby limiting the fixing block 5 and the manhole cover 2.

[0029] The second mounting ring 10 is rotatably connected to the outside of the first mounting ring 3. The inner wall of the second mounting ring 10 is threaded with a first bolt 11, and the bottom of the first bolt 11 is rotatably connected with a limiting piece 12.

[0030] The second mounting ring 10 can be set to easily limit the pipe after installation to prevent shaking and damage to the pipe. It also provides a support point for the installation of the first bolt 11. The cooperation between the first bolt 11 and the limiting piece 12 can further limit the pipe, thereby facilitating the installation and disassembly of the pipe.

[0031] One end of the second mounting ring 10 is threadedly connected to a second bolt 14, and a lever 13 for rotating the second bolt 14 is fixed to the top of the second bolt 14.

[0032] The second bolt 14, in conjunction with the lever 13, facilitates the limiting of the second mounting ring 10, thereby making it easier to install the pipeline.

[0033] The top of the manhole cover 2 is fixed with an installation block 15, and a connecting plate 16 is rotatably connected to the outside of the installation block 15.

[0034] Mounting block 15 can assist the connecting plate 16 in rotating. The setting of connecting plate 16 can facilitate the installation of handle 17 and fixed plate 18.

[0035] A handle 17 is fixed to the top of the connecting plate 16, and a fixing plate 18 is fixed to the bottom of the connecting plate 16.

[0036] The handle 17 is designed to facilitate the opening and closing of the fixing plate 18. The fixing plate 18 is designed to protect the observation port on the manhole cover 2 and prevent foreign objects from entering the interior of the manhole body 1.

[0037] Two pull rings 19 are fixed on the top of the manhole cover 2 for pulling up the manhole cover 2. The inner wall of the fixing plate 18 is rotatably connected to the limiting bolt 20, and the outer side of the limiting bolt 20 is threadedly connected to the inner wall of the manhole cover 2.

[0038] The pull ring 19 facilitates the removal of the manhole cover 2 after it is released from the limit position. The setting of the limit bolt 20 facilitates the limiting of the fixed plate 18, thereby further preventing foreign objects from entering.

[0039] Both ends of the well body 1 are fixed with mounting plates 21 that assist in the assembly and disassembly of the first mounting ring 3. A connecting block 22 is rotatably connected to the outer side of the first mounting ring 3, and the inner wall of the connecting block 22 is rotatably connected to the outer side of the second mounting ring 10.

[0040] Since the mounting plate 21 is not fixed integrally with the first mounting ring 3, the first mounting ring 3 can be easily disassembled during disassembly. The connecting block 22 can increase the extension length of the second mounting ring 10, thereby improving the flexibility of the device.

[0041] Working principle: During installation, the pipe is first placed above the first mounting ring 3, and then the pipe is sent into the well body 1. When the pipe reaches the first mounting ring 3 on the other side of the well body 1, the second mounting ring 10 is rotated to wrap around the pipe. Then, the second bolt 14 at one end of the second mounting ring 10 is rotated to limit the pipe. Then, the first bolt 11 at the top of the second mounting ring 10 is rotated. The first bolt 11 drives the limiting plate 12 to descend, thereby further limiting the pipe. At this point, the installation is complete. Then, the well cover 2 is placed above the well body 1. At this point, the well cover 2 descends, which drives the limiting block 4 to descend. Then, the limiting block 4 squeezes the limiting frame 8. At this point, the limiting frame 8 compresses the first spring 7. When the limiting block 4 descends completely below the limiting frame 8, the compressed first spring 7 rebounds, thereby pushing the limiting frame 8 out to limit the limiting block 4. At this point, the installation of the well cover 2 is complete.
