Description

Technical Field

[0001] This invention belongs to the field of inspection well technology, specifically a prefabricated assembled inspection well. Background Technology

[0002] Inspection wells are installed for the maintenance and installation of drainage and sewage systems in urban underground infrastructure. They are generally located at pipe junctions, bends, changes in pipe diameter or slope, and at regular intervals on straight pipe sections to facilitate periodic inspections of ancillary structures. There are many types of inspection wells, such as sedimentation wells, which can collect impurities such as mud from sewage, allowing the mud to settle within the well.

[0003] In existing technologies, sludge and impurities accumulate inside manholes, requiring regular cleaning and dredging. However, cleaning typically involves workers going down into the manhole to remove the sludge and impurities. Due to prolonged sedimentation, the sludge can solidify, making cleaning difficult. Furthermore, the confined space makes it inconvenient to use specialized tools, requiring a significant amount of manpower and simple tools, greatly reducing the efficiency of manhole cleaning. This is especially problematic when cleaning manholes on roads, as it can obstruct vehicle traffic for extended periods, causing inconvenience.

[0004] Therefore, the present invention provides a prefabricated assembled inspection well. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problem of sludge and impurities accumulating inside manholes, requiring regular cleaning and dredging, the current method typically involves workers entering the manhole to remove the sludge and impurities. However, due to prolonged sedimentation, the sludge can solidify, making cleaning difficult. Furthermore, the confined space makes it inconvenient to use specialized tools, necessitating significant manpower and the use of simple tools, greatly reducing the efficiency of manhole cleaning. This is particularly problematic when cleaning manholes on roads, as it can obstruct vehicle traffic for extended periods, causing significant inconvenience. Therefore, this invention proposes a prefabricated assembled manhole.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A prefabricated assembled inspection well according to this invention includes a well base, a well cylinder, and a well cover; a set of connecting cylinders is provided on the outer wall of the well base; a cleaning seat is provided inside the well base, and the cleaning seat is located below the connecting cylinders; a first groove is provided at the top of the cleaning seat, and the cross-section of the first groove is an inverted isosceles trapezoid; a pair of first guide grooves and a pair of second guide grooves are respectively provided on the side wall of the well base and the side wall of the well cylinder, and the two correspond to each other; a guide plate is fixedly connected in the first guide groove of the well base, and the top of the guide plate is located in the second guide groove; a first sliding groove is provided on the outer wall of the cleaning seat; the first sliding groove is slidably connected to the outer wall of the guide plate; a first conical block is provided at the center of the first groove, and a first pull rod is provided at the top of the first conical block; a fixing column is fixedly connected in the bottom end of the cleaning seat, and the bottom end of the fixing column extends into the first groove. Inside the trough, the first conical block and the fixed column are rotatably connected; a set of stirring rods are provided on the first conical block, and a set of stirring plates are fixedly connected to the stirring rods; a discharge port is opened on the outer wall of the cleaning seat, and the discharge port is connected to the first groove; the stirring rods rotate through the stirring component; the discharge port is opened and closed by the switching component; In the prior art, sludge and impurities will accumulate in the inspection well, which needs to be cleaned and dredged regularly. However, during cleaning, workers usually go down into the well to clean the sludge and impurities. However, due to long-term sedimentation, the sludge inside will solidify, making cleaning inconvenient. In the narrow space, it is also inconvenient to use special tools to operate. It requires a lot of manpower to use simple tools to handle it, which greatly reduces the cleaning efficiency of the inspection well. In particular, when cleaning the inspection wells on the road, it will hinder the vehicle to travel for a long time, causing traffic inconvenience.Therefore, in operation, this invention employs a cleaning seat. During the initial installation of the inspection well, the well base is first assembled, with the guide plate positioned within the first guide groove. Then, the first sliding groove of the cleaning seat is moved downwards along the guide plate, allowing the cleaning seat to be placed at the bottom of the well base, below the connecting cylinder. Next, the well cylinder is installed, aligning the second guide groove with the guide plate for placement. The guide plate serves as a guide. Finally, the well cover is installed. During use, mud or impurities from the water flow through the connecting cylinder will accumulate in the first groove of the cleaning seat. When cleaning is required, the well cover is opened, and using a crane or elevator, the first pull rod is locked, and the entire assembly is moved upwards to allow the cleaning seat to be cleaned. The cleaning seat is guided by a guide plate, allowing most of it to extend outside the manhole. A limiting block at the top of the guide plate prevents the entire cleaning seat from moving out completely. At this point, the discharge port is higher than the manhole cover. The discharge port is then opened via a switch, and an external sludge pump is used to extract the impurities. Simultaneously, as the cleaning seat moves upward, a stirring component agitates the sludge and impurities deposited in the first groove, softening the solidified state and breaking down large solidified impurities for easier discharge. This design eliminates the need for manual manhole entry; existing external machinery can quickly and efficiently clean the manhole without prolonged traffic obstruction.

[0007] Preferably, the agitator includes a third groove; the third groove is formed in the middle of the first groove, and the cross-section of the third groove is inverted T-shaped; an annular plate is rotatably connected to the middle of the third groove, and the top of the annular plate is connected to the bottom of the first conical block; an annular helical gear is rotatably connected to the bottom of the third groove; the annular helical gear drives the annular plate to rotate; the annular helical gear rotates through a power unit; during operation, when the cleaning seat is pulled upward by the first pull rod, the first conical block will be rotated through the power unit, which will then drive the agitator rod and agitator plate to rotate, thereby loosening and breaking up the deposited and solidified sludge impurities, making it convenient to discharge from the outlet. At the same time, the agitator performs agitation when the cleaning seat is moved upward as a whole. When the cleaning seat is above the manhole cover, the sludge impurities in the first groove are in a loose state and can be discharged directly without additional processing.

[0008] Preferably, the power unit includes a rack and a ring gear; a second cavity is provided in the cleaning seat, and the second cavity is interconnected with the first groove and the third groove respectively; a first helical gear is rotatably connected in the second cavity through a rotating shaft, and the first helical gear and the ring helical gear mesh with each other; an annular groove is provided in the middle of the first helical gear, and a ring gear is fixedly connected in the annular groove; a rack is fixedly connected to the side wall of the guide plate, and the rack and the ring gear mesh with each other; during operation, the first helical gear and the ring helical gear mesh with each other, and when the first helical gear rotates, it will drive the ring helical gear to rotate, and then drive the first conical block to rotate through the annular plate. At the same time, because the middle of the helical teeth of the first helical gear is located in the annular groove, the breakage of the middle of the helical teeth of the first helical gear does not affect the meshing operation of the first helical gear and the ring helical gear. At the same time, by utilizing the meshing of the ring gear and the rack, the ring rack moves on the entire cleaning seat, and the ring rack will rotate, thereby driving the first helical gear to rotate, thus completing the above operation. The upward pulling force is used to loosen and break the impurities in the first groove.

[0009] Preferably, the first conical block includes a second conical block, a third conical block, and a fourth conical block, arranged from top to bottom; each of the second, third, and fourth conical blocks is rotatably connected to a fixed column, and each of them has a second groove; a first annular rack is fixedly connected to the bottom of the second groove of the second conical block and to the relative position of the third conical block; a second annular rack is fixedly connected to the bottom of the second groove of the third conical block and to the relative position of the top of the fourth conical block; the top of the annular plate is fixedly connected to the bottom of the second groove of the fourth conical block; the fixed column located in the second groove of the second and third conical blocks is rotatably connected to a first gear via a rotating shaft, and the first gear in the second groove of the second conical block meshes with a pair of first annular racks, and the first gear in the second groove of the third conical block meshes with a pair of second annular racks; a set of stirring rods The gears are respectively installed on the outer walls of the second, third, and fourth conical blocks; the inner diameter of the second annular rack is larger than that of the first annular rack; during operation, the rotation of the annular helical gear drives the fourth conical block to rotate through the annular plate, which in turn drives the third conical block to rotate through the first gear and a pair of second annular racks. At the same time, the rotation of the third conical block drives the second conical block to rotate through the first gear and a pair of second annular racks, causing the fourth and third conical blocks to rotate in opposite directions. This reverse rotation of the third and second conical blocks allows for more thorough mixing. The fourth conical block rotates the slowest, while the second conical block rotates the fastest. Because the fourth conical block is located at the bottom, it slowly stirs the sediment, allowing it to flow. The second conical block, located at the top, handles loose silt and floating objects such as leaves, which can be broken up by high-speed rotation, resulting in different effects.

[0010] Preferably, a pair of first fixing rods are fixedly connected to the inner ring wall of the annular helical gear; a fourth groove is formed at the end of the first fixing rod; a second fixing rod is fixedly connected to the bottom of the fourth groove by a spring; a set of arc-shaped grooves are formed on the outer wall of the annular plate, and the top view of the arc-shaped grooves is a right trapezoid; the second fixing rod is located in the arc-shaped groove, and an arc-shaped surface is formed on the side wall of the second fixing rod, and the arc-shaped surface faces the trapezoidal inclined surface of the arc-shaped groove; the first pull rod includes a second pull rod and a third pull rod; the second pull rod is fixedly connected to the top of the second conical block; the third pull rod is rotatably connected to the second pull rod; a first bevel gear is fixedly connected to the second pull rod; during operation, when the cleaning seat moves upward, the annular helical gear will drive the first fixing rod to rotate, thereby causing the planar side wall of the second fixing rod and the planar side wall of the arc-shaped groove to fit together, thereby driving the annular plate to rotate, allowing it to perform the cleaning operation, but when it moves upward to When discharging from the top, if there are still unmixed and loosened parts, an external device can be used. A motor is placed on the third pull rod via a locking mechanism. The second bevel gear at the motor's output drives the first bevel gear to rotate in the opposite direction, which in turn drives the second pull rod to rotate. This, in turn, moves the second, third, and fourth conical blocks from top to bottom, causing them to rotate and thus perform mixing. Simultaneously, the rotation of the annular plate, using the arc-shaped surface of the second fixed rod and the trapezoidal slope of the arc-shaped groove, prevents the annular plate from rotating the annular helical gear, thus preventing downward movement and facilitating secondary mixing. Furthermore, when lowering the cleaning seat after cleaning impurities, the reverse movement of the annular gear will not cause the first conical block to rotate, effectively avoiding downward resistance and facilitating the placement of the cleaning seat.

[0011] Preferably, a set of annular grooves are formed on the trapezoidal inclined surface of the first groove; a third annular rack is fixedly connected in the annular groove; the ends of the stirring rods rotatably connected to the second, third, and fourth conical blocks are all fixedly connected to a second gear, and the second gear and the third annular rack mesh with each other; during operation, when the cleaning seat moves upward, the second, third, and fourth conical blocks rotate, which in turn drives the stirring rod to rotate around the fixed column, and then through the meshing of the second gear and the third annular rack, the whole structure rotates, allowing the stirring rod to perform a self-rotation operation, thereby increasing the stirring force.

[0012] Preferably, the cleaning seat has an arc-shaped cutting-off groove that cuts off the discharge port; an arc-shaped baffle is placed inside the arc-shaped cutting-off groove; a pull groove is formed on the side wall of the arc-shaped baffle; the arc-shaped cutting-off groove is inclined; during operation, when the discharge port is located inside the well shaft and well base, the arc-shaped baffle is blocked by the inner wall of the well shaft and well base because it is inclined, preventing it from detaching from the inspection well. Only after the discharge port is completely detached from the inspection well can the arc-shaped baffle be pulled out through the pull groove, and at the same time, the port of the sludge pump is turned towards the discharge port to perform sludge pumping operation.

[0013] Preferably, the cross-section of the stirring plate is an isosceles triangle with the tip pointing outwards; the stirring plates on the stirring rods in the second, third, and fourth conical blocks are relatively staggered; during operation, the triangular shape with the tip pointing outwards increases the rotational cutting force, while the staggered distribution of the stirring plates on the upper and lower stirring rods ensures the stirring area and reduces the occurrence of dead corners.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The prefabricated assembled inspection well of the present invention, when cleaning is required, opens the well cover and uses existing devices such as cranes or elevators to lock the first tie rod, and then moves the whole structure upward, allowing the cleaning seat to be guided by the guide plate, so that most of the cleaning seat extends out of the well barrel. Because there is a limiting block at the top of the guide plate, the cleaning seat will not be completely moved out. At this time, the discharge port is higher than the well cover. Then, the discharge port is opened by the switch, and the impurities are extracted by the external tool sludge pump. At the same time, during the upward movement of the cleaning seat, the sludge and impurities deposited in the first groove are stirred by the agitator, making the solidified state into a loose state and breaking up large solidified impurities, which facilitates the discharge of materials from the discharge port. With the above design, no manual operation is required to go down into the well. The cleaning of the inspection well can be completed quickly and efficiently by using existing external machinery, and will not obstruct traffic for a long time.

[0016] 2. The prefabricated assembled inspection well of the present invention utilizes the meshing of a first helical gear and an annular helical gear. When the first helical gear rotates, it drives the annular helical gear to rotate, which in turn drives the first conical block to rotate via an annular plate. Simultaneously, because the middle of the helical teeth of the first helical gear is provided with an annular groove, the breakage of the middle of the helical teeth of the first helical gear does not affect the meshing operation of the first helical gear and the annular helical gear. At the same time, by utilizing the meshing of the annular gear and the rack plate, the cleaning seat moves as a whole, and the annular rack rotates, thereby driving the first helical gear to rotate, thus completing the above operation. The upward pulling force is used to loosen and break up the impurities in the first groove. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 11As shown in the embodiment of the present invention, a prefabricated assembled inspection well includes a well base 1, a well shaft 11, and a well cover 12; a set of connecting cylinders 13 are provided on the outer wall of the well base 1; a cleaning seat 14 is provided inside the well base 1, and the cleaning seat 14 is located below the connecting cylinders 13; a first groove 15 is provided at the top of the cleaning seat 14, and the cross-section of the first groove 15 is an inverted isosceles trapezoid; a pair of first guide grooves 18 and a pair of second guide grooves 19 are respectively provided on the side wall of the well base 1 and the side wall of the well shaft 11, and the two correspond to each other; a guide plate 2 is fixedly connected in the first guide groove 18 of the well base 1, and the top of the guide plate 2 is located in the second guide groove 19; a first sliding groove 21 is provided on the outer wall of the cleaning seat 14; the first sliding groove 21 is slidably connected to the outer wall of the guide plate 2; a first conical block 16 is provided at the center of the first groove 15, and a first pull rod 17 is provided at the top of the first conical block 16; a fixing column 25 is fixedly connected in the bottom end of the cleaning seat 14, and the fixing column 25 is fixedly connected in the bottom end of the cleaning seat 14. 5. The bottom end extends into the first groove 15, and the first conical block 16 and the fixed column 25 are rotatably connected; a set of stirring rods 23 are provided on the first conical block 16, and a set of stirring plates 24 are fixedly connected to the stirring rods 23; a discharge port 22 is opened on the outer wall of the cleaning seat 14, and the discharge port 22 and the first groove 15 are interconnected; the stirring rods 23 rotate through the stirring component; the discharge port 22 is opened and closed by the switching component; In the prior art, sludge and impurities will be deposited in the inspection well, which needs to be cleaned and dredged regularly. However, during cleaning, workers usually go down into the well to clean the sludge and impurities. However, due to long-term sedimentation, the sludge inside will solidify, making cleaning inconvenient. In the narrow space, it is also inconvenient to use special tools to operate. It requires a lot of manpower to use simple tools to handle it, which greatly reduces the cleaning efficiency of the inspection well. In particular, when cleaning the inspection wells on the road, it will hinder the vehicle to travel for a long time, causing traffic inconvenience.Therefore, in operation, this invention employs a cleaning seat 14. During the initial installation of the inspection well, the well base 1 is first assembled, with the guide plate 2 positioned within the first guide groove 18. Then, the first sliding groove 21 of the cleaning seat 14 is moved downwards along the guide plate 2, allowing the cleaning seat 14 to be placed at the bottom of the well base 1, below the connecting cylinder 13. Next, the well cylinder 11 is installed, and the second guide groove 19 is aligned with the guide plate 2 for placement. The guide plate 2 serves as a guide. Finally, the well cover 12 is installed. During use, mud or impurities from the water flow through the connecting cylinder will accumulate in the first groove 15 of the cleaning seat 14. When cleaning is required, the well cover 12 is opened, and using existing devices such as a crane or elevator, the first pull rod 17 is locked, and then the entire... The body moves upward, allowing the cleaning seat 14 to move guided by the guide plate 2, so that most of the cleaning seat 14 extends outside the well casing 11. Because the top of the guide plate 2 has a limiting block, the cleaning seat 14 will not be completely moved out. At this time, the discharge port 22 is higher than the well cover 12. Then, the discharge port 22 is opened by the switch, and the impurities are extracted using an external sludge pump. At the same time, during the upward movement of the cleaning seat 14, the sludge and impurities deposited in the first groove 15 are stirred by the agitator, making the solidified state loose and breaking up large solidified impurities, which facilitates the subsequent discharge from the discharge port 22. With the above design, no manual operation is required in the well. The cleaning of the inspection well can be completed quickly and efficiently using existing external machinery, without obstructing traffic for a long time.

[0031] The stirring component includes a third groove 3; the third groove 3 is formed in the middle of the first groove 15, and the cross-section of the third groove 3 is inverted T-shaped; an annular plate 34 is rotatably connected to the middle of the third groove 3, and the top of the annular plate 34 is connected to the bottom of the first conical block 16; an annular helical gear 31 is rotatably connected to the bottom of the third groove 3; the annular helical gear 31 drives the annular plate 34 to rotate; the annular helical gear 31 rotates through a power unit; during operation, when the cleaning seat 14 is pulled upward by the first pull rod 17, the first conical block 16 will be rotated through the power unit, which will in turn drive the stirring rod 23 and the stirring plate 24 to rotate, thereby loosening and breaking up the deposited and solidified sludge impurities, making it convenient to discharge from the discharge port 22. At the same time, the stirring component is performing stirring treatment when the cleaning seat 14 is moved upward as a whole. When the cleaning seat 14 is above the manhole cover 12, the sludge impurities in the first groove 15 are in a loose state and can be discharged directly without additional processing.

[0032] The power unit includes a rack plate 35 and a ring gear 36; a second cavity 32 is provided in the cleaning seat 14, and the second cavity 32 is interconnected with the first sliding groove 21 and the third groove 3 respectively; a first helical gear 33 is rotatably connected in the second cavity 32 through a rotating shaft, and the first helical gear 33 and the ring helical gear 31 mesh with each other; an annular groove 37 is provided in the middle of the first helical gear 33, and the ring gear 36 is fixedly connected in the annular groove 37; a rack plate 35 is fixedly connected to the side wall of the guide plate 2, and the rack plate 35 and the ring gear 36 mesh with each other; during operation, the first helical gear 33 and the ring helical gear 31 mesh with each other. When the first helical gear 33 rotates, it drives the ring helical gear 31 to rotate, and then drives the first conical block 16 to rotate through the ring plate 34. At the same time, because the middle of the helical teeth of the first helical gear 33 is provided with an annular groove 37, the breakage of the middle of the helical teeth of the first helical gear 33 does not affect the meshing operation of the first helical gear 33 and the ring helical gear 31. Meanwhile, by utilizing the mutual meshing of the ring gear 36 and the rack plate 35, the ring rack moves on the entire cleaning seat 14, and rotates, thereby driving the first helical gear 33 to rotate, thus completing the above operation. By using the upward pulling force, the impurities in the first groove 15 are loosened and broken.

[0033] The first conical block 16 includes a second conical block 4, a third conical block 41, and a fourth conical block 42, arranged from top to bottom; each of the second conical block 4, the third conical block 41, and the fourth conical block 42 is rotatably connected to a fixed post 25, and each of them has a second groove 43; a first annular rack 44 is fixedly connected to the bottom of the second groove 43 of the second conical block 4 and to the relative position of the third conical block 41; a first annular rack 44 is fixed to the bottom of the second groove 43 of the third conical block 41 and to the relative position of the top of the fourth conical block 42. A second annular rack 46 is fixedly connected; the top end of the annular plate 34 is fixedly connected to the bottom of the second groove 43 of the fourth conical block 42; the fixing column 25 located on the column of the second groove 43 of the second conical block 4 and the third conical block 41 is rotatably connected to the first gear 45 through the rotating shaft, and the first gear 45 located in the second groove 43 of the second conical block 4 and a pair of first annular racks 44 mesh with each other, and the first gear 45 located in the second groove 43 of the third conical block 41 and a pair of second annular racks 46 mesh with each other; A set of stirring rods 23 are respectively disposed on the outer walls of the second conical block 4, the third conical block 41, and the fourth conical block 42; the inner diameter of the second annular rack 46 is larger than that of the first annular rack 44; during operation, the rotation of the annular helical gear 31 drives the fourth conical block 42 to rotate through the annular plate 34, and then drives the third conical block 41 to rotate through the first gear 45 and a pair of second annular racks 46. Simultaneously, the rotation of the third conical block 41 drives the second conical block 4 to rotate through the first gear 45 and a pair of second annular racks 46, allowing... The fourth cone block 42 and the third cone block 41 rotate in opposite directions. This allows for more thorough mixing. The fourth cone block 42 rotates the slowest, while the second cone block 4 rotates the fastest. Because the fourth cone block 42 is located at the bottom, it stirs the sediment slowly to allow it to flow. The second cone block 4, located at the top, handles loose silt and floating debris such as leaves, which can be broken up by high-speed rotation, resulting in different effects.

[0034] A pair of first fixing rods 53 are fixedly connected to the inner ring wall of the annular helical gear 31; a fourth groove 54 is formed at the end of the first fixing rod 53; a second fixing rod 55 is fixedly connected to the bottom of the fourth groove 54 by a spring; a set of arc-shaped grooves 57 are formed on the outer wall of the annular plate 34, and the top view of the arc-shaped grooves 57 is a right trapezoid; the second fixing rod 55 is located in the arc-shaped grooves 57, and an arc-shaped surface 56 is formed on the side wall of the second fixing rod 55, and the arc-shaped surface 56 faces the trapezoidal shape of the arc-shaped groove 57. Inclined surface; the first pull rod 17 includes a second pull rod 6 and a third pull rod 61; the second pull rod 6 is fixedly connected to the top of the second conical block 4; the third pull rod 61 is rotatably connected to the second pull rod 6; a first bevel gear 62 is fixedly connected to the second pull rod 6; during operation, when the cleaning seat 14 moves upward, the annular helical gear 31 will drive the first fixed rod 53 to rotate, thereby causing the planar sidewall of the second fixed rod 55 and the planar sidewall of the arc groove 57 to fit together, thereby driving the annular plate 34 to rotate, allowing it to perform... During the cleaning operation, if there are still loose or unmixed parts when the material is discharged from the top, an external device can be used. A motor is placed on the third pull rod 61 via a locking mechanism. The second bevel gear at the motor's output end drives the first bevel gear 62 to rotate in the opposite direction, which in turn drives the second pull rod 6 to rotate. This causes the second, third, and fourth cone blocks 4, 41, and 42 to rotate from top to bottom, thus performing a mixing process. Simultaneously, the rotation of the annular plate 34 drives the arc-shaped surface 56 of the second fixed rod 55 and the trapezoidal inclined surface of the arc groove 57, preventing the annular plate 34 from rotating the annular helical gear 31 and thus preventing downward movement. This also facilitates secondary mixing. Furthermore, when the cleaning seat 14 is lowered after cleaning, the reverse movement of the annular gear 36 will not cause the first cone block 16 to rotate, effectively avoiding downward resistance and facilitating the placement of the cleaning seat 14.

[0035] A set of annular grooves 5 are formed on the trapezoidal inclined surface of the first groove 15; a third annular rack 52 is fixedly connected in the annular groove 5; the ends of the stirring rods 23 rotatably connected to the second conical block 4, the third conical block 41 and the fourth conical block 42 are all fixedly connected to the second gear 51, and the second gear 51 and the third annular rack 52 mesh with each other; during operation, when the cleaning seat 14 moves upward, it will rotate through the second conical block 4, the second conical block 4 and the fourth conical block 42, and then drive the stirring rod 23 to rotate around the fixed column 25. Then, through the meshing of the second gear 51 and the third annular rack 52, it will drive the whole to rotate, so that the stirring rod 23 can perform a self-rotation operation, increasing the stirring force.

[0036] The cleaning seat 14 has an arc-shaped cut-off groove 63 that cuts off the discharge port 22. An arc-shaped baffle 64 is placed inside the arc-shaped cut-off groove 63. A pull groove 65 is provided on the side wall of the arc-shaped baffle 64. The arc-shaped cut-off groove 63 is inclined. During operation, when the discharge port 22 is located inside the well shaft 11 and the well seat 1, the arc-shaped baffle 64 is blocked by the inner wall of the well shaft 11 and the well seat 1 because it is inclined. It will not detach from the inspection well. Only after the discharge port 22 is completely detached from the inspection well can the arc-shaped baffle 64 be pulled out through the pull groove 65. At the same time, the port of the sludge pump is turned towards the discharge port 22 to perform sludge pumping.

[0037] The cross-section of the stirring plate 24 is an isosceles triangle with the tip pointing outwards; the stirring plates 24 on the stirring rods 23 in the second conical block 4, the third conical block 41 and the fourth conical block 42 are relatively staggered; during operation, the triangular shape with the tip pointing outwards can increase the rotational cutting force, and the staggered distribution of the stirring plates 24 on the upper and lower stirring rods 23 can ensure the stirring area and reduce the occurrence of dead corners.

[0038] Working principle: Using the cleaning seat 14, during the initial installation of the inspection well, first assemble and install the well base 1. At this time, the guide plate 2 is located in the first guide groove 18. Then, the first sliding groove 21 of the cleaning seat 14 is moved downward along the guide plate 2, so that the cleaning seat 14 is placed at the bottom of the well base 1, and the cleaning seat 14 is located below the connecting cylinder 13. Then, install the well cylinder 11, and align the second guide groove 19 with the guide plate 2 for placement. The guide plate 2 can guide the placement. Finally, install the well cover 12. During use, mud or impurities in the water flow through the connecting cylinder will be deposited in the first groove 15 of the cleaning seat 14. When cleaning is required, open the well cover 12 and use existing devices such as cranes or elevators to lift the first pull rod 17. The cleaning seat 14 is locked and then moved upwards as a whole, guided by the guide plate 2, so that most of the cleaning seat 14 extends out of the well barrel 11. Because the top of the guide plate 2 has a limiting block, the cleaning seat 14 will not be completely moved out. At this time, the discharge port 22 is higher than the well cover 12. Then, the discharge port 22 is opened by the switch, and the impurities are extracted by the external tool sludge pump. At the same time, during the upward movement of the cleaning seat 14, the sludge and impurities deposited in the first groove 15 are stirred by the agitator, making the solidified state into a loose state and breaking up large solidified impurities to facilitate the subsequent discharge from the discharge port 22. With the above design, no manual operation is required to go down into the well. The inspection well can be quickly cleaned by using existing external machinery. The cleaning process is efficient and rapid, without prolonged traffic obstruction. When the cleaning seat 14 is pulled upward by the first pull rod 17, the power unit drives the first conical block 16 to rotate, which in turn drives the stirring rod 23 and the stirring plate 24 to rotate. This loosens and breaks up the deposited and solidified sludge and impurities, facilitating discharge from the outlet 22. Simultaneously, the stirring component performs agitation as the cleaning seat 14 moves upward. When the cleaning seat 14 is above the manhole cover 12, the settled sludge and impurities in the first groove 15 are loosened and can be directly discharged without further processing. The rotation of the annular helical gear 31 drives the fourth conical block 42 to rotate via the annular plate 34, thereby... The first gear 45 and a pair of second ring racks 46 drive the third conical block 41 to rotate. At the same time, the rotation of the third conical block 41 drives the second conical block 4 to rotate through the first gear 45 and a pair of second ring racks 46, causing the fourth conical block 42 to rotate in the opposite direction to the third conical block 41. This opposite rotation of the third conical block 41 and the second conical block 4 allows for more thorough mixing. The fourth conical block 42 rotates the slowest, while the second conical block 4 rotates the fastest. Because the fourth conical block 42 is located at the bottom, it stirs the sediment slowly, allowing it to flow. The second conical block 4 is located at the top, where loose silt and some floating objects, such as leaves, are broken up by high-speed rotation, producing different effects.When the cleaning seat 14 moves upward, the annular helical gear 31 drives the first fixed rod 53 to rotate, thereby causing the planar sidewall of the second fixed rod 55 and the planar sidewall of the arc-shaped groove 57 to fit together, thus driving the annular plate 34 to rotate for cleaning. However, when it moves to the top, if there are still unmixed and loosened parts during discharge, an external device can be used. A motor is placed on the third pull rod 61 via a locking component. The second bevel gear at the motor output drives the first bevel gear 62 to rotate in the opposite direction, thereby driving the second pull rod 6 to rotate, and thus from the top... The downward movement of the ring plate 34 causes the second conical block 4, the third conical block 41, and the fourth conical block 42 to rotate, thereby performing a stirring process. Simultaneously, the rotation of the ring plate 34 drives the arc-shaped surface 56 and the trapezoidal inclined surface of the arc-shaped groove 57 of the second fixed rod 55, preventing the ring plate 34 from rotating the annular helical gear 31 and thus preventing downward movement. This also facilitates secondary stirring. Furthermore, when the cleaning seat 14 is lowered after cleaning impurities, the reverse movement of the ring gear 36 will not cause the first conical block 16 to rotate as a whole, effectively avoiding downward resistance and facilitating the placement of the cleaning seat 14.
