Description

Technical Field

[0001] This utility model relates to the field of water meter installation technology, and in particular to a water meter well. Background Technology

[0002] To measure users' water consumption, water meters are installed on tap water pipes. For reading and maintenance, water meters are installed in meter wells. Traditional meter wells are mostly pits dug in the ground, lined with bricks and cement, with water supply pipes running through them. Water meters and inlet control valves are installed on the water supply pipes. However, due to their structure, the sealing at the junction of the meter well cover and the well body is poor, allowing mud and water from the outside to easily enter the well. This can cause the electronic components in the water meter to become damp and damaged, resulting in errors in the meter readings and reducing the lifespan of the water meter. Summary of the Invention

[0003] To address the problem of poor sealing at the junction of the manhole cover and the manhole body in existing cement-built water meter wells, this utility model provides a water meter well that achieves a tight fit between the manhole cover and the manhole body by cooperating with a sealing structure set at the manhole cover and a limiting groove opened at the upper end of the manhole body. This reduces the probability of mud and water directly entering the water meter well and improves the service life of the water meter.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A water meter well includes a well body and a well cover. The well body has a placement groove at its upper end for placing the well cover. The longitudinal section of the placement groove is stepped. The well cover, from top to bottom, includes a first cover body and a second cover body. The outer periphery of the first cover body extends beyond the second cover body, and both the first and second cover bodies are fitted into the placement groove. The upper end of the well body also has an annular limiting groove. The outer periphery of the first cover body has an annular mounting groove containing an elastic ring. A sealing ring is also fitted around the outer periphery of the first cover body, with its inner surface contacting the outer surface of the elastic ring. The sealing ring has a first extension at its upper end and a second extension at its lower end. The inner diameters of both the first and second extensions are smaller than the outer diameter of the first cover body. The lower end face of the first extension presses against the upper end face of the first cover body, and the upper end face of the second extension presses against the lower end face of the first cover body. The second extension is embedded in the limiting groove and fits against the groove wall. The limiting groove is located at the bottom of the placement groove and is adapted to the second extension.

[0005] Preferably, both the first and second covers are cylindrical with their axes coincident, and the outer diameter of the first cover is larger than the outer diameter of the second cover. This ensures that the manhole cover matches the stepped placement groove in the longitudinal section, thereby achieving stable placement of the manhole cover on the manhole body.

[0006] Preferably, the placement groove includes a first groove and a second groove, the first groove is located on the upper side of the second groove, the first cover is placed in the first groove, the second cover is placed in the second groove, and the limiting groove is formed on the bottom wall of the first groove.

[0007] Preferably, the inner side of the longitudinal section of the elastic ring is arc-shaped. This conforms to the outer wall of the mounting groove, ensuring the stability of the elastic ring within the groove and preventing it from detaching.

[0008] Preferably, the elastic ring is a ring body made of rubber.

[0009] Preferably, a water supply pipeline is installed through the well body, and a water meter is installed on the water supply pipeline. The water meter is located inside the well body, and two valves are installed on the water supply pipeline. Both valves are located inside the well body and are located on both sides of the water meter.

[0010] Preferably, a platform is fixed to the lower end of the inner side of the well body, and a support base is fixed on the platform, with the water meter fixed on the support base.

[0011] Preferably, a plurality of anti-slip protrusions are evenly provided on the upper surface of the first cover.

[0012] The beneficial effects of this utility model through the above technical solution are as follows: This utility model achieves multiple seals between the manhole cover and the manhole body by setting a matching structure of a sealing ring with upper and lower extensions and a limiting groove, and setting an elastic ring in the installation groove. Under the conditions of thermal expansion and contraction or external vibration, the elastic ring can provide continuous clamping force, keeping the sealing ring and the limiting groove tightly fitted, significantly improving the waterproof and mud-proof ability, and extending the service life of the water meter.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-6 As shown, this embodiment provides a water meter well, including a well body 1 and a well cover 2. The upper end of the well body 1 has a placement groove 3 for placing the well cover 2. The longitudinal section of the placement groove 3 is stepped. (Refer to...) Figure 2 The placement groove 3 includes a first groove and a second groove. The first groove is located on the upper side of the second groove. The manhole cover 2 includes a first cover 21 and a second cover 22 from top to bottom. The outer periphery of the first cover 21 extends out of the second cover 22. The first cover 21 and the second cover 22 are both cylindrical and their axes coincide. The outer diameter of the first cover 21 is larger than the outer diameter of the second cover 22. The first cover 21 and the second cover 22 are both placed in the placement groove 3. The first cover 21 is placed in the first groove and the second cover 22 is placed in the second groove. The limiting groove 4 is opened on the bottom wall of the first groove.

[0016] refer to Figure 2 The upper end of the wellbore 1 is also provided with an annular limiting groove 4, for reference. Figure 3 The first cover 21 has an annular mounting groove 5 on its outer periphery, and an elastic ring 6 is provided inside the mounting groove 5. The inner side of the longitudinal section of the elastic ring 6 is arc-shaped, and the elastic ring 6 is a ring made of rubber. A sealing ring 7 is also fitted around the outer periphery of the first cover 21, and the inner side of the sealing ring 7 contacts the outer side of the elastic ring 6. (Reference) Figure 6 The sealing ring 7 has a first extension 71 at its upper end and a second extension 72 at its lower end. The inner diameters of the first extension 71 and the second extension 72 are both smaller than the outer diameter of the first cover 21. The lower end face of the first extension 71 is pressed against the upper end face of the first cover 21, and the upper end face of the second extension 72 is pressed against the lower end face of the first cover 21. The second extension 72 is embedded in the limiting groove 4 and is tightly fitted to the groove wall of the limiting groove 4.

[0017] The sealing ring 7 and its first extension 71 can be separate parts. After the cover body 2 with the elastic ring 6 is fitted together with the sealing ring 7, the first extension 71 and the sealing ring 7 are pressed together to achieve the assembly of the manhole cover.

[0018] Further, refer to Figure 5A water supply pipe 8 is installed on the well body 1, which supplies tap water to users. A water meter 9 is installed on the water supply pipe 8, which is located inside the well body 1. Two valves 10 are installed on the water supply pipe 8, which are located inside the well body 1 and on both sides of the water meter 9. The two valves 10 control the municipal water supply and the user's water supply respectively, and can shut off the valves in different situations.

[0019] A base 11 is fixed to the lower end of the inner side of the well body 1 to separate the water meter 9 from the lower end of the well body 1, so as to prevent the water meter 9 from getting damp after directly contacting the underground ground. A support base 12 is fixed on the base 11, and the water meter 9 is fixed to the support base 12 by bolts.

[0020] Furthermore, multiple anti-slip protrusions 13 are evenly fixed on the upper surface of the first cover 21 to prevent pedestrians from slipping when walking on the manhole cover 2. At the same time, in order to ensure subsequent inspection and maintenance of the water meter 9, a fixing pull ring can be welded to the first cover 21, so as to make it easier to remove the manhole cover 2 from the manhole body 1.

[0021] When using this device, firstly, dig a pit of a certain area at the preset location and place the well body 1 into it. Then, connect one end of the external municipal water supply pipe to the water supply pipe 8 on the well body 1 through a flange, and then connect the other end of the water supply pipe 8 to the user's water supply pipe through a flange. At this time, the water meter 9 is installed. Then, place the first cover 21 and the second cover 22 in the placement groove 3. The second extension 72 at the lower end of the sealing ring 7 enters the limiting groove 4 and fits against its groove wall. At the same time, the elastic ring 6 is squeezed so that the sealing ring 7 can be tightly embedded in the limiting groove 4. At this time, the first cover 21 fits against the groove wall of the first groove of the placement groove 3, and the second cover 22 fits against the groove wall of the second groove of the placement groove 3, thereby achieving a seal at the connection between the well cover 2 and the well body 1. This makes it difficult for mud and water to enter the inner wall of the well body 1 from the connection between the well body 1 and the well cover 2, reducing the probability of the water meter 9 getting damp and improving its service life.
