Description

Technical Field

[0001] This utility model relates to the field of drainage well technology, and in particular to a modular, leak-proof municipal engineering drainage well. Background Technology

[0002] Drainage wells in municipal engineering are key nodes in urban underground pipe networks. Traditional structures mainly employ on-site masonry or cast-in-place concrete techniques. According to statistics from the Ministry of Housing and Urban-Rural Development, most underground sewage leakage originates from the failure of drainage well joints. Although prefabricated well structures exist in current technology, the joints mostly use simple socket connections, lacking modular sealing designs. Under soil settlement conditions, the joints are prone to misalignment, leading to a loss of seepage prevention capabilities.

[0003] With the advancement of sponge city construction, there is an urgent need to develop a new type of modular drainage well structure with rapid assembly, settlement adaptive sealing, and maintenance-free operation throughout its entire life cycle, so as to fundamentally solve the industry pain point of leakage and pollution of groundwater. Utility Model Content

[0004] The main purpose of this utility model is to provide a modular, leak-proof municipal engineering drainage well, which aims to enable the drainage well to be assembled quickly and stably, and to have good leak-proof performance.

[0005] To achieve the above objectives, this utility model proposes a modular anti-seepage municipal engineering drainage well, including a drainage well body, an inlet pipe located on one side of the drainage well body, and a drainage component located on the other side of the drainage well body. The drainage well body is provided with a partition component, and the inner wall of the drainage well body and the two sides of the partition component are respectively clamped to form an inlet groove and an outlet groove. The inlet pipe is connected to the inlet groove.

[0006] The drainage well body is provided with a sealing component relative to the inlet pipe and / or drainage component, and the drainage component is provided with a sewage pipe and a drainage pipe respectively relative to the inlet tank and the outlet tank.

[0007] In one embodiment of this application, the drainage well body is provided with an open mounting cavity relative to the sealing assembly, and the inner wall of the drainage well body is provided with a through hole coaxially with respect to the mounting cavity. The water inlet pipe and the drainage assembly pass through the mounting cavity and are connected to the through hole.

[0008] In one embodiment of this application, the end of the water inlet pipe is provided with a connector that is connected to the sealing assembly and communicates with the water inlet tank. The connector includes a connecting part for connecting to the water inlet pipe and a locking part provided at the end of the connecting part.

[0009] The diameter of the locking part is larger than the diameter of the connecting part. One side of the locking part is connected to the through hole, and the other side is connected to the sealing component. The sealing component is wrapped around the connecting part.

[0010] In one embodiment of this application, a limiting portion is provided on the outer periphery of the locking portion, and at least two limiting portions are provided symmetrically. The mounting cavity is provided with a limiting component relative to the limiting portion.

[0011] In one embodiment of this application, the limiting component includes at least two limiting structures. The limiting structures are wrapped around the locking portion and connected to one side of the limiting portion. A first locking spring is provided between the limiting structure and the mounting cavity. Adjacent limiting structures are clamped together to form a limiting cavity for clamping the limiting portion.

[0012] In one embodiment of this application, the sealing assembly includes at least two sealing structures, a second locking spring is provided between the sealing structure and the mounting cavity, and the two adjacent sealing structures and the two limiting structures are arranged along the central axis.

[0018] This application relates to a drainage well. The inner cavity of the drainage well body is divided into an inlet channel and an outlet channel by a partition component. The outer wall of the drainage well body is connected to an inlet pipe and a drainage component. The inlet pipe is a mixed inlet pipe used to guide sewage or rainwater into the inlet channel. The drainage component is equipped with a sewage pipe and a drain pipe respectively connected to the inlet channel and the outlet channel. The sewage pipe connected to the inlet channel can achieve the effect of quickly discharging sewage, avoiding sewage accumulation that could cause corrosion and pollution of the inner cavity of the drainage well body. When early rainwater enters through the inlet pipe, it can also be discharged through the sewage pipe. When the rainfall increases and the water becomes clearer, the telescopic rod on the partition component can open the partition component, allowing water to enter the drainage channel.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] Reference Figures 1 to 4To achieve the above objectives, this utility model proposes a modular anti-seepage municipal engineering drainage well, including a drainage well body 1, an inlet pipe 4 located on one side of the drainage well body 1, and a drainage component 5 located on the other side of the drainage well body 1. The drainage well body 1 is provided with a partition component 11. The inner wall of the drainage well body 1 and the two sides of the partition component 11 are respectively clamped to form an inlet groove and an outlet groove. The inlet pipe 4 is connected to the inlet groove.

[0030] The drainage well body 1 is provided with a sealing component 3 relative to the water inlet pipe 4 and / or drainage component 5. The drainage component 5 is provided with a sewage pipe 51 and a drainage pipe 52 respectively relative to the water inlet tank and the water outlet tank.

[0031] This application relates to a drainage well. The inner cavity of the drainage well body 1 is divided into an inlet channel and an outlet channel by a partition component 11. The outer wall of the drainage well body 1 is connected to an inlet pipe 4 and a drainage component 5. The inlet pipe 4 is a mixed inlet pipe 4, used to guide sewage or rainwater into the inlet channel. The drainage component 5 is provided with a sewage pipe 51 and a drain pipe 52 respectively connected to the inlet channel and the outlet channel. The sewage pipe 51 is connected to the inlet channel to achieve the effect of quickly discharging sewage, avoiding sewage accumulation that could cause corrosion and pollution of the inner cavity of the drainage well body 1. When early rainwater enters through the inlet pipe 4, it can also be discharged through the sewage pipe 51. When the rainfall increases and the water becomes clearer, the telescopic rod on the partition component 11 can open the partition component 11, allowing water to enter the drainage channel. There is a certain distance between the drain pipe 52 and the bottom of the drainage channel. This distance forms a sedimentation tank, which can effectively prevent leakage while ensuring the rapid and stable drainage of water.

[0032] The drainage well body 1 is equipped with a sealing component 3 relative to the inlet pipe 4. The sealing component 3 is installed on the drainage well body 1 and faces the inlet and outlet channels. The inlet pipe 4, the sewage pipe 51, and the drain pipe 52 can be quickly and stably connected to the drainage well body 1 through the sealing component 3, and a quick seal is achieved to prevent leakage. Through the above structure, the installation efficiency can be effectively improved.

[0033] See also Figures 2 to 3 The drainage well body 1 is provided with an open mounting cavity 12 relative to the sealing component 3. The inner wall of the drainage well body 1 is provided with a through hole 13 coaxially with the mounting cavity 12. The water inlet pipe 4 and the drainage component 5 pass through the mounting cavity 12 and are connected to the through hole 13.

[0034] The sealing component 3 can be installed in the mounting cavity 12, giving it a certain deformation space. This ensures the sealing component 3 can be locked and installed quickly. It also allows the sealing component 3 and the through hole 13 to be set coaxially, ensuring that the water inlet pipe 4, sewage pipe 51, and drain pipe 52 can be set coaxially with the through hole 13, thus improving the anti-leakage effect.

[0035] See also Figures 1 to 4The end of the water inlet pipe 4 is provided with a connector 41 that is connected to the sealing assembly 3 and communicates with the water inlet tank. The connector 41 includes a connecting part for connecting to the water inlet pipe 4 and a locking part 42 provided at the end of the connecting part.

[0036] The diameter of the locking part 42 is larger than that of the connecting part. One side of the locking part 42 is connected to the through hole 13, and the other side is connected to the sealing component 3. The sealing component 3 wraps around the connecting part. The end of the water inlet pipe 4 is provided with a connector 41, which is composed of the connecting part and the locking part 42. The diameter of the locking part 42 is larger than that of the connecting part. This allows the water inlet pipe 4 (sewage pipe 51, drain pipe 52) to be installed. After the locking part 42 passes through the sealing component 3, the sealing component 3 clamps the connecting part and abuts the locking part 42 against the through hole 13. This structure can effectively achieve a seal and prevent the pipe from coming out. The whole structure is relatively simple, but has a good sealing effect.

[0037] See also Figures 2 to 4 The locking part 42 has a limiting part 43 protruding from its outer periphery. At least two limiting parts 43 are symmetrically provided. The mounting cavity 12 is provided with a limiting component 2 relative to the limiting part 43.

[0038] The limiting part 43 provided on the outer periphery of the locking part 42 can limit the pipe to prevent the pipe from deflecting during use and causing it to loosen. The limiting component 2 is located in the mounting cavity 12 and between the sealing component 3 and the through hole 13.

[0039] At least two opposing limiting parts 43 can enable the limiting component 2 to clamp the entire connector 41 more stably, ensuring the stability of the pipeline installation.

[0040] See also Figures 3 to 4 The limiting component 2 includes at least two limiting structures 21. The limiting structure 21 is wrapped around the locking part 42 and connected to one side of the limiting part 43. A first locking spring is provided between the limiting structure 21 and the mounting cavity 12. Adjacent limiting structures 21 are clamped together to form a limiting cavity for clamping the limiting part 43.

[0041] The limiting component 2 consists of at least two limiting structures 21. The two limiting structures 21 are clamped together to form a limiting cavity, which is positioned towards the limiting part 43. When the connector 41 passes through the sealing component 3, the limiting cavity will clamp the connector 41 to ensure the stability of the pipeline installation and prevent the pipeline from shifting. Even if the pipeline shifts, it can be reset by the first locking spring. The sealing component 3 can limit the pipeline and prevent the pipeline from coming out. This structure can effectively improve the anti-leakage effect.

[0042] See also Figures 3 to 4The sealing assembly 3 includes at least two sealing structures 31, and a second locking spring is provided between the sealing structure 31 and the mounting cavity 12. The two adjacent sealing structures 31 and the two limiting structures 21 are arranged along the central axis.

[0043] The two sealing structures 31 of the sealing assembly 3 can clamp the connecting part of the connector 41 by the second locking spring. The opening and closing positions of the sealing structure 31 and the limiting structure 21 are collinear. When the locking part 42 and the limiting part 43 pass through the sealing structure 31, the limiting part 43 can pass between the two sealing structures 31 and enter the limiting cavity in the limiting structure 21 along the collinear position, making the whole structure easy to install.

[0044] See also Figures 3 to 4 The installation cavity 12 has a relief cavity 14 at its opening. The diameter of the relief cavity 14 gradually increases in the direction away from the through hole 13. The sealing assembly 3 has a guide portion relative to the relief cavity 14.

[0045] The sealing assembly 3 has a guide portion in the opening facing the mounting cavity 12. The diameter of the guide portion gradually increases in the direction away from the through hole 13, so that when the connector 41 is inserted, it can separate the two sealing structures 31 through the guide portion, which makes the entire drainage well structure easy to install. The clearance cavity 14 can give the guide portion a deformation space.

[0046] See also Figures 3 to 4 A sealing ring is provided on the inner wall of the through hole 13, and the water inlet pipe 4 abuts against the sealing ring. The sealing ring is located on the outer periphery of the through hole 13. When the pipe connector 41 is engaged by the limiting component 2 and the sealing component 3, the locking part 42 abuts against the through hole 13 and the sealing ring, which can ensure the sealing effect.

[0047] See also Figure 1 The bottom of the inlet tank gradually decreases in height towards the drain pipe 51. This slope ensures rapid discharge of wastewater.

[0048] See also Figure 1 The sewage pipe 51 is connected to a water pump, which can ensure the rapid discharge of sewage through active drainage.
