[0001] The utility model relates to the technical field of prefabricated inspection wells, in particular to an assembled prefabricated inspection well. Background Art

[0002] The installation and construction of traditional prefabricated inspection wells generally adopt the on-site mortar installation method, which has a long installation and construction period, high labor intensity, low efficiency, and is greatly affected by weather and site conditions. It causes huge pollution to the surrounding environment, the construction quality is also unstable, and the cost is high; especially the connection between the external pipe and the inspection well is a weak link.

[0003] The existing authorization announcement number is CN206512750U, which discloses a prefabricated inspection well, including a base, a well chamber, a well ring, and a well cover connected in sequence from bottom to top. The base is provided with an external pipe hole, which is surrounded by embedded bolts. The reserved external pipe hole is fixed with a prefabricated joint via embedded bolts and nuts. The base and the well chamber are connected by an arc-shaped double-headed screw, and the well chamber and the well ring are connected by an arc-shaped double-headed screw. The free end of the prefabricated joint is an enlarged port with a bolt hole reserved in the enlarged port. A rubber sealing ring is provided at the connection between the reserved external pipe hole and the prefabricated joint. The connection between the base, well chamber, and well ring is a concave-convex plug-in connection, and the connection between the base, well chamber, and well ring is provided with a waterproof pad. The structural design is reasonable, and the prefabricated inspection well components are mechanically assembled on site. The installation is convenient and quick. It is factory-produced and has good overall stability.

[0004] With the above-mentioned technical solution, although the base and the well chamber are connected by a curved double-ended screw, and the well chamber and the well ring are connected by a curved double-ended screw, due to the structural characteristics of the curved double-ended screw, it may experience stress concentration when subjected to external forces, causing damage or breakage of the screw. Secondly, the installation process of the curved double-ended screw is relatively complex and requires professional technicians to operate. Otherwise, improper installation may occur, affecting the effectiveness and safety of the inspection well. Therefore, we provide a prefabricated assembly inspection well. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figures 1-4As shown, in this embodiment, an assembled prefabricated inspection well comprises: an installation mechanism 1, the installation mechanism 1 comprises a base 11, a well chamber 12 is provided on the top of the base 11, a well ring 13 is provided on the top of the well chamber 12, a sealing ring 15 is provided on the outside of the well chamber 12, the bottom of the well chamber 12 is fixedly connected to the top of the base 11, the inner ring of the sealing ring 15 is fixedly connected to the outside of the well chamber 12, a well cover 14 is docked in the slot opened on the top of the well ring 13, a well cover 14 is provided on the top of the well ring 13, four plug-ins 16 are provided in an annular array at the bottom of the well ring 13, a fixing groove 17 is provided on the outside of the four plug-ins 16, threaded grooves 18 are respectively provided on the outside of the well ring 13 near the four plug-ins 16, bolts 19 are provided on the outside of the sealing ring 15 near the threaded groove 18, four plug-ins 16 are fixedly connected in an annular array at the bottom of the well ring 13, one end of the bolt 19 passes through the sealing ring 15 and is threadedly connected to the inner wall of the threaded groove 18, the top of the well chamber 12 The annular array is provided with four slots 110 that are compatible with the plug-in block 16, and the annular array outside the sealing ring 15 is provided with four connecting blocks 111. The four connecting blocks 111 are provided with connecting rods 112 on one side close to the sealing ring 15. The outside of the plug-in block 16 is inserted into the slot 110, and the end of the connecting rod 112 close to the connecting block 111 passes through the card slot opened on the outside of the sealing ring 15 and is movably connected to the inside of the connecting block 111. The four connecting rods 112 are provided with fixed blocks 114 on one side away from the connecting block 111. The end of the connecting rod 112 away from the connecting block 111 is fixedly connected to one side of the fixed block 114, and the other side of the fixed block 114 is clamped in the fixing groove 17. The outside of the four connecting rods 112 is provided with a spring 113, and the end of the spring 113 away from the fixed block 114 is fixedly connected to the inner wall of the card slot opened in the sealing ring 15 close to the side of the connecting block 111. A quick release mechanism 2 is provided inside the well ring 13.

[0024] In this embodiment, when the staff needs to assemble the prefabricated inspection well, the staff can first detent the four connecting blocks 111. When the connecting blocks 111 are detent, they will be squeezed against the outside of the sealing ring 15, and the connecting blocks 111 will be flipped over. Therefore, the connecting rod 112 and the fixing block 114 will be flipped over by the connecting block 111 and move toward the outside of the sealing ring 15. During the movement of the fixing block 114, the spring 113 will be gradually squeezed and deformed. Then the staff can insert the well ring 13 into the slot 110 provided at the top of the well chamber 12 through the insert block 16. Therefore, the positioning effect will be completed between the well ring 13 and the well chamber 12, which is convenient for subsequent installation. Loosening the pre-fastened connecting block 111 will cause the spring 113 to lose its extrusion force and release the elastic force, thereby pushing the fixing block 114 to be engaged in the fixing groove 17 opened on one side of the plug block 16, and then the well ring 13 and the well chamber 12 can be fixed and installed. The connection between the bolt 19 and the threaded groove 18 makes the well chamber 12 and the well ring 13 more tightly fixed together, reducing the loosening phenomenon that may occur during use, thereby ensuring the structural stability of the prefabricated inspection well and avoiding potential safety hazards caused by loosening.

[0025] like Figure 3-Figure 4 As shown, the quick-release mechanism 2 includes a mounting seat 21, the outside of the mounting seat 21 is fixedly connected to the inner wall of the well ring 13, two mounting grooves 22 are provided on the top of the mounting seat 21, and an escalator 23 is provided on one side of the mounting seat 21. The escalator 23 is fixedly connected to two hooks 24 near one side of the mounting seat 21, and one end of the hook 24 is inserted into the mounting groove 22.

[0026] In this embodiment, when the staff needs to use the escalator 23 to go down the well, the hook 24 provided on one side of the escalator 23 can be inserted into the mounting groove 22 opened on the top of the mounting seat 21, so that the escalator 23 will be hung on the mounting seat 21, which is convenient for the installation and disassembly of the escalator 23. Therefore, during daily maintenance and inspection, the staff can operate more conveniently, thereby reducing maintenance costs.

[0027] The utility model provides an assembled prefabricated inspection well, the specific working principle of which is as follows:

[0028] When the staff needs to assemble the prefabricated inspection well, they can first detent the four connecting blocks 111. Once the connecting blocks 111 are detent, they will squeeze the outside of the sealing ring 15. This squeezing will cause the connecting blocks 111 to flip over, and then the connecting rod 112 and the fixing block 114 will be moved toward the outside of the sealing ring 15 due to the flipping of the connecting blocks 111. During the movement of the fixing block 114, it will gradually exert pressure on the spring 113 and cause it to shrink and deform. This deformation is one of the characteristics of the spring 113. It can change its shape when subjected to external force and return to its original shape after the external force disappears. Next, the staff can insert the well ring 13 into the top of the well chamber 12 through the plug 16. There is a slot 110 provided, which is designed to accommodate the plug block 16 to ensure that the well ring 13 can be correctly installed on the well chamber 12. When the staff releases the pre-locked connecting block 111, the spring 113 will lose the extrusion force and release the elastic force. This elastic force will push the fixing block 114 to be clamped in the fixing groove 17 opened on one side of the plug block 16. In this way, the well ring 13 and the well chamber 12 can be fixed and installed. In order to ensure that the well chamber 12 and the well ring 13 are more tightly fixed together, the staff can use bolts 19 and threaded grooves 18 for connection. This connection method can effectively reduce the loosening phenomenon that may occur during use and improve the stability and reliability of the entire prefabricated inspection well.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
