[0002] Inspection wells are set up for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and street light lines. They are easy to install and are generally located at pipeline intersections, bends, places where pipe diameters or slopes change, and at certain intervals on straight pipe sections to facilitate regular inspection of ancillary structures.
[0003] At present, a manhole cover is usually installed on the top of the inspection well, which closes the wellhead, blocks debris, and improves the safety of pedestrians and vehicles passing through the wellhead. However, it is still easy for a lot of debris to mix into the inflow pipe of the inspection well. These debris enter the outflow pipe from the inspection well, which can easily cause the outflow pipe to be blocked or even collapsed. Utility Model Content
[0004] In order to improve the problem that pipelines are prone to blockage or even collapse, the present application provides an inspection well.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-5 This application is described in further detail.
[0033] An embodiment of the present application discloses an inspection well.
[0034] Reference Figure 1 The inspection well includes a well body 1, a well cover 2, a grille plate 3, a filter frame 4 and a lifting mechanism 5.
[0035] Reference Figure 1 , Figure 2 The well body 1 is embedded in the ground. In the present embodiment, the well body 1 is a frame body cast with reinforced concrete. The interior of the well body 1 is hollow and the upper end is open. The pipeline is connected to the side wall of the well body 1 near the bottom. The well cover 2 is installed on the top of the well body 1. The well cover 2 closes the upper end opening of the well body 1. In the present embodiment, the well cover 2 is made of cast iron and has the characteristics of corrosion resistance and high strength. A limiting block 7 is installed at the bottom of the well cover 2. A through hole 13 is opened on the side wall of the well body 1 near the top. A limiting hole 12 is opened circumferentially on the side wall of the well body 1 near the top. The limiting hole 12 is connected with the through hole 13. The through hole 13 is used for the limiting block 7 to be inserted into the limiting hole 12. In the present embodiment, two limiting blocks 7 are installed at the bottom of the well cover 2, and two groups of limiting holes 12 and through holes 13 are opened on the well body 1.
[0036] The staff moves the manhole cover 2 so that the limit block 7 is aligned with the through hole 13, then moves the manhole cover 2 downward so that the limit block 7 is stuck in the through hole 13, and then enters the limit hole 12 from the through hole 13, and then rotates the manhole cover 2, and the manhole cover 2 drives the limit block 7 to rotate into the limit hole 12, so that the two sides of the limit block 7 can abut against the upper and lower side walls of the limit hole 12, completing the positioning and installation of the manhole cover 2 at the upper end opening of the well body 1. The manhole cover 2 closes the upper opening of the well body 1, blocks the debris on the upper part of the well body 1, and effectively improves the stability of the manhole cover 2 on the well body 1.
[0037] Reference Figure 1, Figure 3 The grille plate 3 is hingedly mounted on the inner wall of the well body 1, and the hinge axis between the grille plate 3 and the well body 1 is located above the connection between the well body 1 and the outflow pipe. The grille plate 3 blocks the connection between the well body 1 and the outflow pipe.
[0038] After water enters the well body 1 from the inflow pipe, it flows out from the outflow pipe. Due to the action of gravity and the impact force of the water when it flows out, the grille plate 3 can be attached to the inner wall of the well body 1, blocking the connection between the well body 1 and the outflow pipe, and then blocking the debris outside the outflow pipe, preventing the debris from clogging the outflow pipe, and effectively improving the problem that the pipe is prone to blockage or even collapse. In addition, the staff can turn the grille plate 3 upward away from the connection between the well body 1 and the outflow pipe to enter the outflow pipe for maintenance.
[0039] Reference Figure 1 , Figure 3 A ladder 6 is installed on the side wall of the well body 1. In this embodiment, the ladder 6 is composed of a plurality of U-shaped steel bars, which are pre-buried on the side wall of the well body 1 at intervals along the vertical direction, so that the ladder 6 extends from the upper opening of the well body 1 to the bottom wall of the well body 1. The staff opens the well cover 2, and then can go down from the ladder 6 to the well body 1, or derive from the well body 1 to the upper opening of the well body 1, which effectively improves the convenience of the staff entering and exiting the well body 1.
[0040] Reference Figure 1 , Figure 3 A embedding groove 11 is provided on the bottom wall of the well body 1, and the opening size of the embedding groove 11 gradually decreases from the direction close to the well cover 2 to the direction away from the well cover 2. A filter frame 4 is installed abutting the bottom of the embedding groove 11. The height of the filter frame 4 is lower than the height of the bottom wall of the well body 1. The cross-sectional size of the filter frame 4 also gradually decreases from the direction close to the well cover 2 to the direction away from the well cover 2. The bottom wall of the well body 1 gradually tilts downward from the side wall of the well body 1 toward the filter frame 4.
[0041] The inclined bottom wall of the well body 1 guides the debris entering the well body 1 from the inflow pipe and the debris blocked by the grille plate 3, so that the debris entering the well body 1 slides from the inclined bottom wall of the well body 1 into the filter frame 4, and the filter frame 4 can sink and collect the debris in the well body 1, preventing the debris from accumulating on the bottom wall of the well body 1 and affecting the circulation of water, thereby reducing the possibility of the well body 1 and the grille plate 3 being blocked; and through the embedded groove 11 whose opening size gradually decreases from the direction close to the well cover 2 to the direction away from the well cover 2, when the staff installs the filter frame 4 whose cross-sectional size gradually decreases from the direction close to the well cover 2 to the direction away from the well cover 2 into the embedded groove 11, it is easy to install the filter frame 4 into the embedded groove 11, thereby improving the convenience of the staff in embedding and installing the filter frame 4 into the embedded groove 11.
[0042] Reference Figure 3 , Figure 4 A lifting mechanism 5 is installed on the well body 1, and the lifting mechanism 5 is used to lift the filter frame 4 to the upper opening of the well body 1. The lifting mechanism 5 includes a winding drum 51, a pull rope 52, a hook 53 and a winding assembly 54. The drum is rotatably installed on the side wall of the well body 1 near the upper opening, the pull rope 52 is wound around the drum, and a plurality of hooks 53 are installed at the end of the pull rope 52 away from the winding drum 51. In this embodiment, the pull rope 52 is a steel rope, and a plurality of lifting rings 8 are installed on the filter frame 4. One hook 53 is hooked on one lifting ring 8, and a guide rod 9 is installed on the side wall of the well body 1. The pull rope 52 is wound around the guide rod 9, and the guide rod 9 guides the pull rope 52 so that the lower part of the pull rope 52 can act on the filter frame 4 more vertically.
[0043] Reference Figure 3 , Figure 5 The winding assembly 54 is installed on the winding disk 51, and the winding assembly 54 is used to drive the winding disk 51 to rotate. The winding assembly 54 includes a crank handle 541, a ratchet 542, a pawl 543 and a spring 544. The crank handle 541 is coaxially installed on the winding disk 51, the ratchet 542 is coaxially installed on the winding disk 51, the pawl 543 is hingedly installed on the side wall of the well body 1, one end of the spring 544 is installed on the side wall of the well body 1, and the other end of the spring 544 is installed on the pawl 543. The spring 544 always has a tendency to drive the pawl 543 to abut against the ratchet 542. When the winding disk 51 rotates in the direction of releasing the pull rope 52, the pawl 543 is clamped on the ratchet 542 to limit the ratchet 542 from continuing to rotate.
[0044] When it is necessary to clean the debris in the filter frame 4, the staff releases the pull rope 52 from the reel 51, then hooks the multiple hooks 53 on the pull rope 52 to the ring 8 on the filter frame 4, and then rotates the crank 541, which drives the reel 51 to rotate, so that the reel 51 reels the pull rope 52, and the pull rope 52 can pull the filter frame 4 out of the embedded groove 11 and move it up to the upper end opening of the well body 1, so that the staff can deal with the debris collected in the filter frame 4, which effectively improves the staff's processing of the debris collected in the filter frame 4. The convenience of removing debris; and in the process of the reel 51 reeling up the pull rope 52, the reel 51 drives the ratchet 542 to rotate, and the ratchet 542 pushes the pawl 543 away from the ratchet 542, so that the ratchet 542 can rotate in the direction of reeling up the pull rope 52. If the reel 51 tends to rotate in the direction of releasing the pull rope 52, the pawl 543 is clamped onto the ratchet 542 under the action of the spring 544, thereby restricting the ratchet 542 and the reel 51 from rotating in the direction of releasing the pull rope 52, thereby improving the safety of the staff in lifting the filter frame 4.
[0045] Reference Figure 3A plurality of water leakage holes 41 are provided on the side wall of the filter frame 4 . When the staff lifts the filter frame 4 , the water in the filter frame 4 can leak out from the water leakage holes 41 , making it easy for the staff to lift the filter frame 4 .
[0046] The implementation principle of an inspection well in an embodiment of the present application is as follows: the grating plate 3 in the well body 1 blocks the connection between the well body 1 and the outflow pipe under the impact of gravity and the water in the pipe flowing in and out of the well body 1, thereby blocking the debris outside the outflow pipe to prevent the debris from clogging the outflow pipe, and the debris can slide into the filter frame 4 to sink and be collected, effectively improving the problem of the pipeline being prone to blockage or even collapse.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
