Description

Technical Field

[0001] This utility model relates to the field of urban underground infrastructure, and in particular to a sedimentation inspection well. Background Technology

[0002] Inspection wells are installed to facilitate the maintenance and installation of underground infrastructure such as power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and street light lines in cities. They are generally located at pipe intersections, bends, changes in pipe diameter or slope, and at regular intervals on straight pipe sections to facilitate periodic inspections of the ancillary structures.

[0003] A sedimentation well is a manhole with a sedimentation tank (chamber) at the bottom to settle sediment in the pipes. Manholes with sedimentation tanks do not require a flow channel. Sedimentation wells are only suitable for rainwater drainage systems.

[0004] Once the sedimentation tank is filled with silt, it needs to be cleaned. This requires going down to the bottom of the well, and the limited space inside makes the cleaning process quite difficult. Utility Model Content

[0005] The purpose of this invention is to provide a sedimentation inspection well, which has the advantage of eliminating the need to descend to the bottom of the well to clean the sediment in the sedimentation tank, thus reducing the difficulty of cleaning.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A sedimentation inspection well includes a well body with opposing inlet and outlet ports near its bottom. A placement groove is provided at the bottom of the well body, with its upper opening located below the inlet and outlet ports. The inner diameter of the placement groove is smaller than the inner diameter of the well body. A basket is embedded in the placement groove, and a sedimentation box is embedded in the basket. Two opposing pulley seats are fixedly connected to the end face of the upper opening of the basket. The line connecting the two pulley seats is perpendicular to the line connecting the inlet and outlet ports. Each pulley seat is rotatably connected to a pulley. The well body contains... Two pulley seats 2 are fixedly connected to the wall near the wellhead. Each pulley seat 2 is rotatably connected to two pulleys. The two pulley seats 2 are located above the two pulley seats 1, and the two pulley seats 1 and the two pulley seats 2 are respectively opposite each other. It also includes two lifting ropes. One end of each lifting rope is fixedly connected to the inner wall of the well near the wellhead. The other end of the lifting rope first passes under the pulley on the pulley seat 1, then passes between the two pulleys of the pulley seat 2 opposite to the pulley seat 1, and is then tied to the side wall of the well through a connector.

[0008] Using the above technical solution, two workers or an angle grinder pull two hoisting ropes respectively. The two ropes are taut, each exerting force on the pulley of pulley seat one through which it passes, thereby pulling the pulley of pulley seat one and the suspended basket upwards. Once the suspended basket is near the wellhead, the hoisting ropes are tied to the connecting piece to secure the basket. Then, the sediment box in the basket is removed, the sediment is emptied, and it is placed back into the basket; or a new sediment box is directly installed. The sediment box removed from the basket is then... During the next cleaning, the basket is transferred back to the hoisting basket. After cleaning, the hoisting rope is loosened, and the basket and sediment box are placed back into the sedimentation trough at the bottom of the well. Then, the end of the hoisting rope is tied to the connector. There is no need to go down to the bottom of the well to clean the mud and sand. The cleaning is not restricted by the space inside the well. At the same time, through the combination of pulley one and pulley two, the well body bears part of the weight of the basket, sediment box and mud and sand during the process of pulling the basket up, thereby reducing the force required by workers or machines and making it more labor-saving.

[0009] Preferably, the well body sidewall is fixedly connected with two opposing vertical slide rails, and the upper end face of the basket is provided with two slots opposite to the two slide rails. The two slots respectively embed the two slide rails, and the slide rails are slidably connected to the basket.

[0010] Using the above technical solution, pulling the hoisting rope causes the suspended basket to move upward along the slide rail. The slide rail limits and guides the movement of the suspended basket, making the suspended basket rise more stably.

[0011] Preferably, rollers are rotatably connected to the two side walls of the two slots of the suspended basket, and the rollers are in contact with the slide rail, and the rollers are in rolling connection with the slide rail.

[0012] Using the above technical solution, the suspended platform rises and drives the rollers on its upper part to move along the slide rail. At the same time, the force between the rollers and the slide rail causes the rollers to rotate. The rotating rollers reduce the sliding friction between the suspended platform and the guide rail, thereby reducing the resistance encountered by the suspended platform when it moves.

[0013] Preferably, the movable end of the hoisting rope is equipped with a pull ring, and a hook is connected to the side wall of the well body, with the hook engaging the pull ring.

[0014] Using the above technical solution, after pulling the hoisting rope to bring the basket to the wellhead, the hoisting rope is tied to the hook to prevent the basket from falling.

[0015] Preferably, the sedimentation box has two opposing handles fixedly connected to its upper opening.

[0016] Using the above technical solution, the sludge box can be easily removed from the basket via a handle.

[0017] In summary, this embodiment eliminates the need to descend to the bottom of the well to remove mud and sand, making it more convenient. Furthermore, the combination of pulleys reduces the force required to lift the basket, the slide rails facilitate a smoother ascent, and the rollers rolling along the slide rails reduce the resistance encountered during the basket's ascent.

[0025] See Figures 1 to 4 A sedimentation inspection well includes a well body 1 with two opposing inlet and outlet ports near its bottom. A placement groove 2 is provided at the bottom of the well body 1, with its upper opening located below the inlet and outlet ports, and the inner diameter of the placement groove 2 being smaller than the inner diameter of the well body 1. A hanging basket 3 is embedded within the placement groove 2, and a sedimentation box 4 is embedded within the hanging basket 3. Two opposing handles 14 are fixedly connected to the upper opening of the sedimentation box 4.

[0026] See Figure 2 , Figure 4 and Figure 5Two opposing pulley seats 5 are fixedly connected to the end face of the upper opening of the suspended platform. The line connecting the two pulley seats 5 is perpendicular to the line connecting the inlet and outlet. Pulleys 6 are rotatably connected to pulley seats 15. Two pulley seats 2 are fixedly connected to the inner wall of the well body 1 near the well opening. Pulley seats 2 are fixedly connected to the inner wall of the well body 1 by welding to the embedded parts cast on the inner wall of the well body 1. Each pulley seat 2 is rotatably connected to two pulleys 6. The two pulley seats 2 are located above the two pulley seats 15, and the two pulley seats 15 and the two pulley seats 2 are opposite each other. Two pre-embedded parts are cast on the inner wall of the well body 1 near the well opening. Each pre-embedded part is welded with a hook 11. Each hook 11 is attached with a lifting rope 8. The other end of the lifting rope 8 passes under the pulley 6 on the pulley seat 1 5 and then passes between the two pulleys 6 on the pulley seat 2 7 opposite to the pulley seat 1 5. The movable end of the lifting rope 8 is attached with a pull ring 12. The side wall of the well body 1 is connected to the hook 11, and the hook 11 hooks the pull ring 12.

[0027] See Figure 2 and Figure 3 Two opposing vertical slide rails 9 are fixedly connected to the side wall of the well body 1. The slide rails 9 are welded to the embedded parts on the inner wall of the well body 1 or fixed to the inner wall of the well body 1 by expansion bolts, or the slide rails 9 are integrally cast with the well body 1. The upper end face of the hanging basket 3 is provided with two slots 10 opposite to the two slide rails 9. The two slots 10 of the hanging basket 3 respectively embed the two slide rails 9. The slide rails 9 are slidably connected to the hanging basket 3. Rollers 13 are rotatably connected to the inner walls of the two sides of the limiting plate slot 10. The inner side wall of the slot 10 has a cavity. The rollers 13 are embedded in the cavity. The two ends of the rollers 13 are fixedly connected to the rotating shafts. The rotating shafts of the rollers 13 are rotatably connected to the inner walls of the two sides of the cavity. The rollers 13 are in contact with the slide rails 9 and are tumbled together with the slide rails 9.

[0028] Working principle: Two workers hold the pull rings 12 of the two hoisting ropes 8 respectively, pulling them taut. Each rope 8 exerts a force on the pulley 6 of its respective pulley seat 5, thus pulling the pulley 6 and the suspended basket 3 upwards. The suspended basket 3 moves the roller 13 in its groove 10 along the slide rail 9. Simultaneously, the force between the roller 13 and the slide rail 9 causes the roller 13 to rotate, reducing the resistance encountered by the suspended basket 3 during its ascent. When the suspended basket 3 reaches near the wellhead, the hoisting ropes 8 are tied to the hooks 11 to secure the suspended basket 3 and prevent it from falling back to its original position. Then, the sedimentation box 4 in the suspended basket 3 is removed, the sediment is emptied, and it is placed back into the suspended basket 3; or a new sedimentation box 4 is directly installed, and the sedimentation box 4 removed from the suspended basket 3 is replaced during the next cleaning. After cleaning, unhook the hoisting rope 8 from the hook 11, loosen the rope 8, and lower the basket 3 and sediment box 4 back into the sedimentation trough at the bottom of the well body 1. Then, attach the pull ring 12 at the end of the hoisting rope 8 to the hook 11. There is no need to go down to the bottom of the well to clean the sediment, and the cleaning process is not restricted by the space inside the well body 1. Furthermore, through the combination of pulley 6 of pulley seat 1 and pulley seat 2 7, the well body 1 bears part of the weight of the basket 3, sediment box 4, and sediment during the lifting of the basket 3, thus reducing the effort required from workers or machines and making the process more labor-saving.
