Description

Technical Field

[0001] This utility model belongs to the technical field of water meter installation and supporting facilities, specifically referring to a quick-sealing water meter well. Background Technology

[0002] Water meter wells are important structures protecting water meters, valves, and other water supply facilities. They are widely used in municipal water supply and residential communities. Their ease of installation and sealing performance directly affect the protection effect and subsequent maintenance efficiency. However, traditional water meter wells have significant shortcomings: 1. The lack of a precise alignment structure during assembly makes it difficult to align the top cover, well body, and bottom trench. It requires multiple people to work together and make repeated adjustments, which takes a long time to install. Especially in scenarios with limited construction space, the assembly efficiency is extremely low. 2. The sealing structure is simple and relies on a single rubber gasket for sealing. With long-term use, rainwater and mud may seep in due to displacement or aging of the seal, damaging the internal water meter and pipes, increasing maintenance costs, and making it difficult to meet the needs of long-term stable protection.

[0003] To address this issue, a rapid-sealing water meter well is proposed. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional water meter wells suffer from difficulties in assembly and alignment, low installation efficiency, poor sealing performance, and easy leakage.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a quick-sealing water meter well includes an upper cover, a central shell, and a bottom groove. A sealing ring is arranged around both the upper and lower ends of the central shell. A second receiving groove adapted to the sealing ring is fixedly opened on the upper cover and the bottom groove. Fastening components for fixing the three are fixedly arranged at the connection points of the upper cover, the central shell, and the bottom groove, as well as auxiliary components for aligning the upper cover with the central shell and the central shell with the bottom groove.

[0006] Furthermore, the fastening assembly includes a second fixing plate and a first fixing plate symmetrically fixed to both sides of the central shell, and another set of first fixing plate and second fixing plate 2 that cooperate with the second fixing plate and first fixing plate 1 at the central shell are fixedly connected to both the upper cover and the side walls of the bottom groove. The first fixing plate is threaded with a bolt, and the lower end of the bolt passes through the second fixing plate. The lower end of the second fixing plate is provided with a nut for fixing the first fixing plate and the second fixing plate 2 and threaded onto the bolt.

[0007] Furthermore, the auxiliary component includes a set of fixed seats that are symmetrically connected to the other two side walls of the upper cover and the bottom groove. A connecting block is fixedly connected to the lower end of the fixed seat. The upper and lower side walls of the central shell are provided with first receiving grooves that are adapted to the connecting block and allow it to extend into them.

[0008] Furthermore, two L-shaped blocks are slidably arranged on one side wall of the connecting block. Each of the two L-shaped blocks has a semi-threaded hole fixedly opened at its opposite end. A compression bolt is provided at the upper end of the semi-threaded hole. The two semi-threaded holes together form a threaded hole into which the compression bolt extends.

[0009] Furthermore, the width of the assembly of the connecting block and the L-shaped block is the same as the width of the inner wall of the first receiving groove, and the length of the assembly of the two L-shaped blocks and the extrusion bolt is the same as the length of the inner wall of the first receiving groove.

[0010] Furthermore, the length of the compression bolt extending into the hole is equal to the length of the semi-threaded hole.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows: 1. The device extends the connecting block of the upper cover into the first receiving groove at the upper end of the central shell and the connecting block of the bottom groove into another set of first receiving grooves at the lower end of the central shell. Then, the extrusion bolt is turned to enter the semi-threaded hole, which drives the two L-shaped blocks to slide relative to each other, so that the connecting block and the L-shaped block assembly fit tightly against the inner wall of the first receiving groove. The alignment of the upper cover, central shell and bottom groove is automatically completed without repeated adjustments. It can be operated by a single person, which greatly shortens the installation time. 2. In the fastening assembly, after the bolts pass through the mating fixing plate one and fixing plate two, the three are rigidly fixed by tightening the nuts, which prevents the components from shifting during long-term use; at the same time, the sealing rings at the upper and lower ends of the central shell are embedded in the second receiving groove of the upper cover and the bottom groove to form an annular sealing structure. Combined with the tight fit of the rigid fixation, it effectively prevents rainwater and mud from seeping in, extends the service life of the internal water meter and pipes, and reduces maintenance costs.

[0015] 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. Example 1:

[0016] like Figures 1 to 4 As shown, the auxiliary component structure and application of a quick-sealing water meter well are as follows: The auxiliary component includes a fixing seat 4 fixed to the other two side walls of the upper cover 1 and the bottom groove 3. The lower end of the fixing seat 4 is integrally formed with a connecting block 10. The upper and lower side walls of the central shell 2 are provided with a first receiving groove 5 that is adapted to the size of the connecting block 10 and allows it to extend into it. A sliding groove is provided on one side wall of the connecting block 10. Two L-shaped blocks 11 are slidably arranged in the sliding groove. The opposite ends of the two L-shaped blocks 11 are provided with semi-threaded holes 12. The upper end of the semi-threaded holes 12 is provided with a compression bolt 13. The two semi-threaded holes 12 are spliced ​​together to form a complete internal threaded hole, and the internal thread is adapted to the external thread of the compression bolt 13.

[0017] The width of the assembly after the connecting block 10 and the L-shaped block 11 are slidably spliced ​​together is exactly the same as the width of the inner wall of the first receiving groove 5. The length of the assembly after the two L-shaped blocks 11 and the extrusion bolt 13 are assembled is the same as the length of the inner wall of the first receiving groove 5. The maximum insertion length of the extrusion bolt 13 into the semi-threaded hole 12 is equal to the length of the semi-threaded hole 12 itself, so as to avoid excessive extrusion and damage to the parts.

[0018] In use, first place the bottom groove 3 stably in the designated construction position. Hold the center shell 2 and align its lower end first receiving groove 5 with the connecting block 10 below the fixing seat 4 on the bottom groove 3. Slowly slide it in until the connecting block 10 is fully inserted into the first receiving groove 5. Then take the top cover 1 and align the connecting block 10 below its fixing seat 4 with the first receiving groove 5 at the upper end of the center shell 2. Slide it in to achieve initial positioning. Then use a tool to tighten the clamping bolt 13. The clamping bolt 13, through the threaded drive of the semi-threaded hole 12, pushes the two L-shaped blocks 11 to slide relative to each other along the sliding groove of the connecting block 10 until the combination of the connecting block 10 and the L-shaped block 11 is tightly attached to the inner wall of the first receiving groove 5. At this time, the axes of the top cover 1, the center shell 2, and the bottom groove 3 are completely aligned, completing the precise alignment. The whole process does not require the cooperation of multiple people and can be completed by a single person. Example 2:

[0019] Based on Example 1, such as Figures 1 to 4 As shown, the fastening assembly includes a second fixing plate 7 and a first fixing plate 6 symmetrically welded to the outer walls of both sides of the central shell 2 (the first fixing plate 6 is located on the upper side and the second fixing plate 7 is located on the lower side). The lower ends of the two side walls of the upper cover 1 are fixedly connected to the second fixing plate 7, which cooperates with the first fixing plate 6 at the central shell 2. The upper ends of the two side walls of the bottom groove 3 are fixedly connected to the first fixing plate 6, which cooperates with the second fixing plate 7 at the central shell 2. The corresponding first fixing plate 6 and the second fixing plate 7 are both provided with through holes for the bolt 14 to pass through. The inner wall of the through hole on the first fixing plate 6 is provided with internal threads, which are adapted to the external threads of the bolt 14. After the lower end of the bolt 14 passes through the second fixing plate 7, the threaded part is fitted with a nut 15 for locking. Meanwhile, the upper and lower ends of the central shell 2 are both surrounded by sealing rings 8 made of aging-resistant rubber. The bottom of the upper cover 1 and the top of the bottom groove 3 are both provided with annular second receiving grooves 9 that are adapted to the size of the sealing rings 8. The thickness of the sealing rings 8 is slightly greater than the depth of the second receiving grooves 9 to ensure that the gaps can be fully filled after being pressed.

[0020] In use, after achieving precise alignment of the three components as described in Example 1, take bolt 14 and screw it into the upper fixing plate 6 (on the side of the upper cover 1 or the side of the central shell 2), so that the lower end of bolt 14 passes through the corresponding fixing plate 7 (on the side of the central shell 2 or the side of the bottom groove 3) until the end of bolt 14 extends out of fixing plate 7. Then, put nut 15 into the end of bolt 14 and tighten nut 15 with a wrench until fixing plate 6 and fixing plate 7 are tightly fitted. At this time, the upper cover 1, the central shell 2, and the bottom groove 3 are rigidly fixed as one, preventing displacement due to vibration or external force during long-term use.

[0021] Furthermore, the tightened bolts and nuts compress the sealing rings 8 at the upper and lower ends of the central shell 2, causing the sealing rings 8 to be fully embedded in the second receiving groove 9 of the upper cover 1 and the bottom groove 3. After being compressed, the sealing rings 8 undergo elastic deformation, filling the tiny gaps between the second receiving groove 9 and the end face of the central shell 2, effectively preventing rainwater and sediment from seeping in from the connection point and ensuring the long-term stable operation of internal water meters, valves, and other facilities. For later maintenance, simply unscrew the nut 15 and loosen the bolt 14 with a wrench to release the tightness; the operation is convenient.
