Description

Technical Field

[0001] This utility model relates to the field of sewage well technology, specifically a prefabricated modular sewage well component. Background Technology

[0002] The precast component industry is developing rapidly, and precast sewage wells, as an important part of it, mostly adopt an integrated fixed structure, which is convenient for installation. These precast components are usually composed of two parts: the well body and the well cover. The integrated design effectively improves construction efficiency, reduces on-site pouring time, and ensures structural strength and sealing. Its standardized production mode also reduces material waste, making it an efficient solution in urban infrastructure construction and widely used in municipal drainage system renovation and new construction projects.

[0003] Sewage well covers are typically placed at the well opening solely by their own weight, lacking an effective fixing structure. When vehicles frequently drive over them, the cover and the edge of the well opening are prone to displacement due to long-term impact, causing the cover edge to lift up. This design flaw not only affects driving stability but may also cause safety hazards due to cover displacement, such as cover falling off or causing potholes in the road surface. Utility Model Content

[0004] The purpose of this invention is to provide a prefabricated modular sewage well to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated modular sewage well, comprising a well cover body and a well body, and further comprising: The pin groove mechanism consists of a first pin groove, a second pin groove, and a side groove. The first and second pin grooves are both located at the top of the well body, and the side groove is located on the surface of the side wall of the first pin groove. The positioning pin mechanism consists of multiple pins, which are respectively used to insert into the first pin groove, the second pin groove, and the side groove.

[0006] Preferably, the positioning pin mechanism includes: The vertical pin has a hollow interior and is used to insert into the first pin groove. The vertical pin extends through the surface of the manhole cover body. The second locating pin has a circular cross-section and is used to insert into the interior of the second pin groove; The first positioning pin has an inclined design at one end. The first positioning pin passes through the side of the vertical pin and slides through the inner wall of the through point. The first positioning pin is used to insert into the lateral groove. A screw is rotatably connected to the inside of the vertical pin, and the top end of the screw extends to the top of the vertical pin and is bolted with a rotating block. A threaded sleeve is threaded to the surface of the screw, and a wedge-shaped block that contacts the first locating pin is bolted to one side of the threaded sleeve. A sliding component is used to keep the wedge block in vertical motion and limit its range of motion; The elastic component provides elastic force to the first locating pin so that it fits against the surface of the wedge block.

[0007] Preferably, the sliding component includes: A groove is formed on the surface of the wedge-shaped block; The vertical bar is bolted to the inner wall of the vertical pin, and the inner wall of the groove is slidably connected to the surface of the vertical bar; Two sets of limiting blocks are attached to the upper and lower sides of the vertical strip surface, respectively. The upper and lower limiting blocks limit the upper and lower movement range of the wedge block.

[0008] Preferably, the elastic component includes: Two sets of sliding sleeves are bolted to the side of the first positioning pin. The sliding rod is bolted to the surface of the inner wall of the vertical pin and slidably connected to the inner wall of the sliding sleeve; A compression spring is sleeved on the surface of the slide rod, with both ends in contact with the inner walls of the slide sleeve and the vertical pin, respectively. The force of the compression spring causes the first positioning pin to fit against the wedge block.

[0009] Preferably, the surface of the wedge block away from the slide groove is inclined, and the surface of the first positioning pin near the wedge block is inclined.

[0010] Preferably, the length of the screw is greater than the length of the vertical bar.

[0011] Preferably, the surface of the manhole cover body is further provided with a groove, and a lifting ring is fixed to the inner wall of the groove.

[0012] Preferably, the top of the lifting ring is lower than the top of the manhole cover body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention effectively solves the problem of traditional manhole covers easily warping by using a coordinated design of a pin groove mechanism and a positioning pin mechanism. Specifically, the vertical pin, the first pin groove, and the second pin groove form a vertical limiting structure, which, together with the lateral groove and the lateral locking of the first positioning pin, constructs a three-dimensional positioning system. This system can resist the vertical impact and lateral displacement when a vehicle runs over it. The mechanical locking method of the threaded sleeve driving the wedge block to push the first positioning pin, combined with the automatic reset function of the compression spring, ensures both convenient installation and improved disassembly and assembly efficiency. This design, through the linkage structure of the screw and the rotating block, achieves precise positioning of the manhole cover body and the manhole, significantly enhancing the manhole cover's resistance to deformation, reducing the frequency of municipal maintenance, and ensuring driving safety and road surface smoothness.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-9 As shown, a prefabricated modular sewage well includes a well cover body 100 and a well body 300. The prefabricated part also includes a pin groove mechanism 400 and a positioning pin mechanism 200. The pin groove mechanism 400 is composed of a first pin groove 410, a second pin groove 420 and a side groove 430. The first pin groove 410 and the second pin groove 420 are both opened on the top of the well body 300, and the side groove 430 is opened on the surface of the side wall of the first pin groove 410.

[0018] The positioning pin mechanism 200 consists of multiple pins for insertion into the first pin groove 410, the second pin groove 420, and the lateral groove 430. Specifically, the positioning pin mechanism 200 includes a vertical pin 210, a second positioning pin 290, a first positioning pin 270, a screw 220, a threaded sleeve 240, a sliding assembly 260, and a spring assembly 280. The vertical pin 210 has a hollow interior and is used to insert into the first pin groove 410. The vertical pin 210 penetrates the surface of the manhole cover body 100. The second positioning pin 290 has a circular cross-section. It is used to insert into the interior of the second pin groove 420. One end of the first positioning pin 270 is designed to be inclined. The first positioning pin 270 passes through the side of the vertical pin 210 and is slidably connected to the inner wall of its penetration. The first positioning pin 270 is used to insert into the side groove 430. The screw 220 is rotatably connected to the inner side of the vertical pin 210. The top end of the screw 220 extends to the top of the vertical pin 210 and is bolted with a rotating block 230. The threaded sleeve 240 is threadedly connected to the surface of the screw 220. A wedge block 250 that contacts the first positioning pin 270 is bolted to one side of the threaded sleeve 240.

[0019] The sliding assembly 260 is used to keep the wedge block 250 in vertical motion and limit its range of motion. Further, the sliding assembly 260 includes a groove 261, a vertical bar 262, and a limiting block 263. The groove 261 is formed on the surface of the wedge block 250. The vertical bar 262 is bolted to the inner wall of the vertical pin 210. The inner wall of the groove 261 is slidably connected to the surface of the vertical bar 262. There are two sets of limiting blocks 263, which are bolted to the upper and lower sides of the surface of the vertical bar 262 respectively. The upper and lower limiting blocks 263 limit the vertical movement range of the wedge block 250. The length of the screw 220 is greater than the length of the vertical bar 262. During the vertical movement, the wedge block 250 will contact the limiting block 263 to prevent the wedge block 250 from moving too widely and losing contact with the first positioning pin 270.

[0020] The elastic component 280 provides elastic force to the first locating pin 270, causing it to conform to the surface of the wedge block 250. Furthermore, the elastic component 280 includes a sliding sleeve 281, a sliding rod 283, and a compression spring 282. There are two sets of sliding sleeves 281, which are bolted to the side of the first positioning pin 270. The sliding rod 283 is bolted to the surface of the inner wall of the vertical pin 210 and slidably connected to the inner wall of the sliding sleeve 281. The compression spring 282 is sleeved on the surface of the sliding rod 283 and its two ends are in contact with the sliding sleeve 281 and the inner wall of the vertical pin 210, respectively. The force of the compression spring 282 makes the first positioning pin 270 and the wedge block 250 fit together. The surface of the wedge block 250 away from the slide groove 261 is inclined. The surface of the first positioning pin 270 near the wedge block 250 is also inclined.

[0021] The surface of the manhole cover body 100 is also provided with a groove 110. A lifting ring 120 is fixed to the inner wall of the groove 110. The manhole cover body 100 can be lifted by passing a rope through the lifting ring 120. The top of the lifting ring 120 is lower than the top of the manhole cover body 100 to prevent the lifting ring 120 from being too high after the manhole cover is installed and being run over by vehicles.

[0022] After the well body 300 is installed, the vertical pin 210 is aligned with the first pin groove 410 and the second positioning pin 290 is aligned with the second pin groove 420 by hoisting the well cover body 100. Then, the well cover body 100 is lowered so that the vertical pin 210 enters the interior of the first pin groove 410 and the second positioning pin 290 enters the interior of the second pin groove 420. Then, the rotating block 230 is rotated by using a socket wrench. The rotating block 230 drives the screw 220 to rotate. The threaded sleeve 240 on the surface of the screw 220 drives the wedge block 250 to descend and uses the inclined plane to push the first positioning pin 270 to move to the outside of the vertical pin 210 and then into the interior of the lateral groove 430, thus completing the positioning of the well cover body 100 and the well body 300.

[0023] During the process of the vehicle running over the manhole cover, the manhole cover body 100 tends to lift up. The vertical pin 210 abuts against the inner wall of the first pin groove 410, while the second positioning pin 290 abuts against the inner wall of the second pin groove 420 to prevent the manhole cover body 100 from lifting up. Running over the edge of the manhole cover will cause the other end of the manhole cover to make an arc movement and lift up. Therefore, the pin and groove can prevent this kind of arc movement. At the same time, the first positioning pin 270 enters the interior of the side groove 430 to further implement positioning to prevent the manhole cover itself from being lifted off the manhole by the vertical upward force. If it is necessary to remove the manhole cover, simply rotate the screw 220 in the opposite direction to drive the wedge block 250 upward. Then, the first positioning pin 270 retracts under the action of the compression spring 282 to release the positioning. After that, the manhole cover itself can be lifted vertically.
