Description

Technical Field

[0001] This utility model relates to the field of inspection well technology, and in particular to an HDPER inspection well structure. Background Technology

[0002] With the continuous deepening of urbanization and the transformation and upgrading of infrastructure construction in my country, the requirements for municipal water storage systems, the "lifeblood" of the city, are increasing. As a key node in the pipeline system, the performance of manholes is crucial to the safety, durability, and operational efficiency of the entire system. Traditional brick and concrete manholes, due to their inherent defects such as low construction efficiency, poor reliability, and insufficient durability, can no longer meet the needs of modern urban construction. Against this backdrop, HDPER manholes have emerged and, with their superior comprehensive performance, have demonstrated broad market prospects and development potential. HDPER materials are resistant to corrosion from acids, alkalis, salts, greases, and other chemicals, with a service life of over 50 years, far exceeding traditional materials. This significantly reduces the maintenance cost throughout the entire life cycle. They also offer excellent sealing, good flexibility, and impact resistance, effectively adapting to uneven foundation settlement and avoiding rupture due to settlement like rigid manholes, resulting in higher safety performance.

[0003] The existing HDPER manhole structure typically uses rubber gaskets to seal the manhole cover and the manhole body. After long-term use, the rubber gaskets will wear down, affecting the sealing effect. Regular replacement of the rubber gaskets is required, increasing maintenance costs. Secondly, the connection between the manhole and the pipeline may loosen and leak due to long-term water flow impact.

[0004] Therefore, those skilled in the art have provided an HDPER inspection well structure to address the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an HDPER inspection well structure that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an HDPER inspection well structure, comprising an inspection well body, an inspection well cover connected to the upper end of the inspection well body via a connecting shaft, a sealing mechanism provided on the inspection well body, the sealing mechanism including an embedded groove formed at the upper end of the inspection well body, two connecting columns symmetrically arranged on the inspection well body, one end of the two connecting columns located in the internal space of the inspection well body and fixedly connected to an arc-shaped block, one end of the two connecting columns located inside the embedded groove and fixedly connected to an arc-shaped strip, and a first sealing rubber gasket connected to the arc-shaped strip.

[0007] As a further technical solution of this utility model, the sealing mechanism also includes an embedded column fixedly connected to the lower end of the manhole cover, and a second sealing rubber gasket is fixedly connected to the embedded column, wherein the first sealing rubber gasket and the second sealing rubber gasket can be in full contact.

[0008] As a further technical solution of this utility model, the sealing mechanism also includes a limiting ring fixedly connected to the lower end of the manhole cover. The limiting ring can contact the arc-shaped block, and the contact surface between the arc-shaped block and the limiting ring is arc-shaped.

[0009] As a further technical solution of this utility model, the volume of the embedded column is much smaller than that of the embedded groove, and the first sealing rubber gasket and the second sealing rubber gasket are both under compression when they come into contact.

[0010] As a further technical solution of this utility model, the inspection well body is provided with multiple pipe inlets, and a filter mechanism is provided on each pipe inlet. The filter mechanism includes a movable ring provided on the pipe inlet, and a filter screen is provided on the movable ring.

[0011] As a further technical solution of this utility model, the filter mechanism also includes a movable groove opened on the inlet of the connecting pipe, and a movable block is fixedly connected to the outer wall of the movable ring. The movable block is located inside the movable groove and is connected by a spring column.

[0012] As a further technical solution of this utility model, the filter mechanism is provided in multiple sets, the number of which is consistent with the number of pipe inlets.

[0013] As a further technical solution of this utility model, a corrugated pipe is provided on the outer wall of the inspection well body.

[0014] This utility model provides an HDPER inspection well structure, which has the following advantages compared with the prior art:

[0015] By incorporating a movable sealing mechanism, the manhole cover achieves a good sealing effect when closed, preventing sewage from seeping into groundwater and avoiding secondary pollution. It also blocks the escape of harmful gases, reducing the risk of explosion and the spread of odors. Furthermore, even when the sealing rubber gaskets wear out, they remain tightly attached to each other, without affecting the sealing effect, eliminating the need for frequent gasket replacements. Additionally, the movable filtration mechanism prevents groundwater and debris from entering the manhole, while the spring column provides a buffering effect, preventing loosening between the manhole and the pipeline.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for the structure of an HDPER inspection well: it includes an inspection well body 1, the upper end of the inspection well body 1 is connected to an inspection well cover 5 via a connecting shaft 4, a sealing mechanism is provided on the inspection well body 1, the sealing mechanism includes an embedding groove 6 opened at the upper end of the inspection well body 1, two connecting columns 9 are symmetrically arranged on the inspection well body 1, one end of the two connecting columns 9 is located in the internal space of the inspection well body 1 and is fixedly connected to an arc-shaped block 8, one end of the two connecting columns 9 is located inside the embedding groove 6 and is fixedly connected to an arc-shaped strip 10, a first sealing rubber pad 11 is connected to the arc-shaped strip 10, the first sealing rubber pad 11 is in a compressed state when it is in the initial position, and the diameter of the two first sealing rubber pads 11 is larger than the diameter of the arc-shaped strip 10.

[0023] The sealing mechanism also includes an embedded column 7 fixedly connected to the lower end of the inspection well cover 5. A second sealing rubber gasket 12 is fixedly connected to the embedded column 7. The first sealing rubber gasket 11 and the second sealing rubber gasket 12 can fully contact each other and are fully pressed together to improve the sealing effect.

[0024] The sealing mechanism also includes a limiting ring 18 fixedly connected to the lower end of the manhole cover 5. The limiting ring 18 can contact the arc-shaped block 8. The contact surface between the arc-shaped block 8 and the limiting ring 18 is arc-shaped. When the limiting ring 18 moves with the manhole cover 5 into the interior of the manhole body 1, it will push the arc-shaped block 8 into the interior of the manhole body 1.

[0025] The size of the embedded column 7 is much smaller than that of the embedded groove 6, and the first sealing rubber gasket 11 and the second sealing rubber gasket 12 are both under compression when they come into contact.

[0026] The main body 1 of the inspection well is provided with multiple pipe inlets 2. Each pipe inlet 2 is equipped with a filter mechanism. The filter mechanism includes a movable ring 13 installed on the pipe inlet 2. The movable ring 13 is equipped with a filter screen 14, which can filter groundwater debris.

[0027] The filtration mechanism also includes a movable groove 15 opened on the inlet 2, and a movable block 16 is fixedly connected to the outer wall of the movable ring 13. The movable block 16 is located inside the movable groove 15 and is connected by a spring column 17.

[0028] The filter mechanism is provided in multiple sets, the number of which is the same as the number of pipe inlets 2. The pipe inlets 2 are used to connect the inlet pipe and the outlet pipe. The filter mechanism on the pipe inlet 2 connected to the inlet pipe will move into the interior of the inspection well body 1, and the filter mechanism on the pipe inlet 2 connected to the outlet pipe will move outward from the inspection well body 1.

[0029] A corrugated pipe 3 is installed on the outer wall of the main body 1 of the inspection well.

[0030] The working principle of this utility model is as follows: When it is necessary to seal the manhole body 1 through the manhole cover 5, it is only necessary to rotate the manhole cover 5 through the connecting shaft 4 to seal the manhole body 1 from the top. At the same time, the embedded column 7 and the limiting ring 18 move with the manhole cover 5. First, the embedded column 7 will move into the inside of the embedded groove 6, achieving the first seal. When the limiting ring 18 enters the inside of the manhole body 1, it will push the arc-shaped block 8 to move, thereby driving the arc-shaped strip 10 to move through the connecting column 9, so that the first sealing rubber gasket 11 and the second sealing rubber gasket 12 can fully contact each other to achieve a second seal. At the same time, when the seal is closed... Even when the rubber gaskets wear out, they can still adhere tightly together without affecting the sealing effect. This eliminates the need for frequent replacement of the gaskets, thus extending their service life. When groundwater enters the manhole body 1 through the pipe, the filter screen 14 installed on the pipe inlet 2 blocks impurities in the water, preventing them from directly entering the manhole body 1. Simultaneously, under the impact of the water flow, the movable ring 13 and the filter screen 14 move based on the movable groove 15 via the movable block 16, thereby squeezing the spring column 17. The spring column 17 also provides a certain buffering effect, preventing loosening between the manhole and the pipe.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
