Description

Technical Field

[0001] The utility model relates to the technical field of water meter wells, in particular to a water meter well that can be quickly closed and sealed. Background Technique

[0002] A water meter well usually refers to a well or box for installing a water meter, which is an underground or ground structure for placing the water meter and related equipment. Water meter wells are usually used in the water supply systems of cities and communities. The water meter is usually installed in the well. The design and placement of the water meter well make the water meter not easily damaged or vandalized by humans, and at the same time prevent the theft of the water meter. The specific form and design of the water meter well will vary depending on the region and the water supply system. Generally speaking, the water meter well is an important facility that can ensure the safe, effective operation and convenient maintenance of the water meter.

[0003] At present, when the water meter wells on the market are in use, a sealing ring with the same upper and lower widths of the cross-section is directly used to seal the connection. The sealing ring with the same upper and lower widths cannot make the water meter well tighter and tighter during the assembly process, resulting in insufficient tight closure between the various parts of the water meter well. Therefore, we propose a water meter well that can be quickly closed and sealed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water meter well that can be quickly closed and sealed to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water meter well that can be quickly closed and sealed, including an upper well body, a well cover, a heightening section and a lower well body. A metal anti-falling net is arranged above the upper well body, and heat insulation cotton is arranged above the metal anti-falling net. The well cover is installed above the heat insulation cotton, and a wellhead sealing ring is jointly arranged between the well cover and the upper well body. The lower part of the upper well body is installed with a heightening section, and the lower part of the heightening section is installed with a lower well body. A positioning groove is opened on the surface of the lower well body, and a flange sealing ring is arranged inside the positioning groove. A support seat is arranged on the upper edge of the lower well body, and a docking groove is opened on the inner wall of the heightening section close to the support seat.

[0006] Preferably, the support seat is correspondingly inside the docking groove, and a bolt penetrates through the edge of the lower well body.

[0007] Preferably, a washer is sleeved above the bolt, and a nut is sleeved above the bolt close to the washer.

[0008] Preferably, a through groove is opened at the lower part of the lower well body, and a sealing sleeve is correspondingly inserted inside the through groove. Plugging grooves are opened on the two side surfaces of the lower well body close to the through groove.

[0009] Preferably, a limiting groove is formed inside one side of the insertion slot, and an insertion block is arranged inside the insertion slot.

[0010] Preferably, the outer end of the insertion block is connected to the edge of the sealing sleeve, and a limiting block penetrates through one side of the insertion block close to the limiting groove.

[0011] Preferably, a spring is arranged inside the insertion block, and two ends of the spring are respectively connected to the inner wall of the insertion block and the limiting block.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this water meter well that can be quickly closed and sealed, through the mutual cooperation between the flange sealing ring and the positioning groove, the closure between the water meter wells is tighter, enabling the water meter well to be quickly closed and sealed. The limiting block is used to limit the position between the sealing sleeve and the lower well body, facilitating the limiting installation of the sealing sleeve for this sewage filter and preventing it from falling off easily.

[0013] 1. For this water meter well that can be quickly closed and sealed, when assembling the water meter well, first place the narrower side of the flange sealing ring from top to bottom corresponding to the inside of the positioning groove. As the heightening section is pressed downwards, the heightening section will squeeze the flange sealing ring inside the positioning groove downwards. During the squeezing process, the flange sealing ring will become tighter with the inverted isosceles trapezoid positioning groove. Finally, pass the bolt through the edge of the lower well body, place the gasket above the bolt, and then place the nut above the bolt and tighten it. Through the mutual cooperation between the flange sealing ring and the positioning groove arranged between the heightening section and the lower well body, the closure between the water meter wells is made closer, thus enabling the water meter well to be quickly closed and sealed.

[0014] 2. For this water meter well that can be quickly closed and sealed, first connect the sealing sleeve from outside to inside into the inside of the through groove and press the sealing sleeve inwards to the limit position. At this time, the positions of the limiting block and the limiting groove correspond. Therefore, the limiting block not subjected to external extrusion can automatically reset outwards under the elastic force of the spring and correspond to the inside of the limiting groove. By arranging a telescopic limiting block inside the insertion block to limit the position between the sealing sleeve and the lower well body, it is convenient for this sewage filter to limit the installation of the sealing sleeve and prevent it from falling off easily.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1 、 Figure 2 and Figure 3 , the present utility model provides a technical solution: a water meter well that can be quickly closed and sealed, including an upper well body 1, a manhole cover 4, a heightening section 6, and a downhole body 7. A metal anti-falling net 2 is provided above the upper well body 1, and thermal insulation cotton 3 is provided above the metal anti-falling net 2. The manhole cover 4 is installed above the thermal insulation cotton 3, and a wellhead sealing ring 5 is jointly provided between the manhole cover 4 and the upper well body 1. The heightening section 6 is installed below the upper well body 1, and the downhole body 7 is installed below the heightening section 6. A positioning groove 8 is provided on the surface of the downhole body 7, and a flange sealing ring 9 is provided inside the positioning groove 8. A support seat 10 is provided at the upper edge of the downhole body 7, and a docking groove 11 is provided on the inner wall of the heightening section 6 close to the support seat 10. The thermal insulation cotton 3 can effectively prevent the water pipes inside the water meter well from freezing in cold weather.

[0022] The support seat 10 corresponds to the inside of the docking groove 11, and a bolt 12 penetrates through the edge of the downhole body 7; a washer 13 is sleeved above the bolt 12, and a nut 14 is sleeved above the bolt 12 close to the washer 13. Both the wellhead sealing ring 5 and the flange sealing ring 9 are made of rubber. The cross-sectional shape of the positioning groove 8 is an inverted isosceles trapezoid, and the cross-sectional dimensions of the support seat 10 match the cross-sectional dimensions of the docking groove 11.

[0023] During specific implementation, when assembling the water meter well, first place the narrower side of the flange sealing ring 9 from top to bottom corresponding to the inside of the positioning groove 8. Then, fit and dock the heightening section 6 with the lower well body 7. As the heightening section 6 is pressed downward, the heightening section 6 will squeeze the flange sealing ring 9 inside the positioning groove 8 downward. During the squeezing process, the flange sealing ring 9 can be made to fit more tightly with the inverted isosceles trapezoidal positioning groove 8. At the same time, the support seat 10 on the lower well body 7 corresponds to the inside of the docking groove 11 to provide axial support for the water meter well. Finally, pass the bolt 12 through the edge of the lower well body 7, sleeved the washer 13 above the bolt 12, and finally sleeve the nut 14 above the bolt 12 and tighten it to complete the sealed assembly of the water meter well. Through the mutual cooperation between the flange sealing ring 9 and the positioning groove 8 provided between the heightening section 6 and the lower well body 7, the closure of the water meter well is made more tight, so that the water meter well can be quickly closed and sealed.

[0024] Please refer to Figure 1 , Figure 2 and Figure 4 , a through groove 15 is opened below the lower well body 7, and a sealing sleeve 16 is correspondingly inserted inside the through groove 15. Plug-in grooves 17 are opened on both side surfaces of the lower well body 7 close to the through groove 15; a limiting groove 18 is opened inside one side of the plug-in groove 17, and a plug-in block 19 is arranged inside the plug-in groove 17; the outer end of the plug-in block 19 is connected to the edge of the sealing sleeve 16, and a limiting block 20 penetrates through one side of the plug-in block 19 close to the limiting groove 18; a spring 21 is arranged inside the plug-in block 19, and both ends of the spring 21 are respectively connected to the inner wall of the plug-in block 19 and the limiting block 20. The plug-in grooves 17 are symmetrically distributed about the center line of the through groove 15. The size of the limiting block 20 matches the size of the limiting groove 18, and the limiting block 20 and the plug-in block 19 form a telescopic structure through the spring 21.

[0025] In specific implementation, first, the sealing sleeve 16 is butted into the inside of the through groove 15 from the outside to the inside, and the sealing sleeve 16 is pressed inward. As the sealing sleeve 16 moves inward, the plug-in blocks 19 provided on the sealing sleeve 16 correspond to the plug-in grooves 17 one by one. As the sealing sleeve 16 is continuously pressed, the inner wall of the plug-in groove 17 will squeeze the limit block 20. The limit block 20 under external force extrusion moves into the inside of the plug-in block 19 while squeezing the connected spring 21 until the sealing sleeve 16 is pressed to the limit position. At this time, the plug-in block 19 is completely butted inside the plug-in groove 17, and the positions of the limit block 20 and the limit groove 18 correspond. Therefore, the limit block 20 not under external force extrusion can automatically reset outward through the elastic force of the spring 21, so that the limit block 20 corresponds to the inside of the limit groove 18, and the sealing sleeve 16 can be assisted in being limited. By arranging the retractable limit block 20 inside the plug-in block 19 to limit between the sealing sleeve 16 and the downhole body 7, the sewage filter can facilitate the limit installation of the sealing sleeve 16 and is not easy to fall off.

[0026] In summary, when using the water meter well that can be quickly closed and sealed, first, move each part of the water meter well to the designated use area. Then, install the water meters one by one through the through grooves 15 inside the downhole body 7. The water meters installed inside the downhole body 7 can avoid being damaged by humans. Finally, lock and install between the riser section 6 and the downhole body 7 through the bolts 12 and nuts 14, and also lock and install between the upper well body 1 and the riser section 6 through the bolts 12 and nuts 14 to complete the assembly of the water meter well. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
