Description

Technical Field

[0001] The utility model belongs to the technical field of inspection wells, and more specifically, particularly relates to an antifreeze inspection well. Background Art

[0002] Inspection wells are plastic drainage pipes buried in building areas (residential areas, public building areas, factory areas, etc.) with an outer diameter of no more than 800mm and a buried depth of no more than 6m. They are generally located at the intersection of drainage pipes, turning points, places where pipe diameters or slopes change, waterfalls, etc., in order to facilitate regular inspection, cleaning and dredging or downhole operation inspection. They are made of plastic one-piece injection molding or brick-built well-shaped structures;

[0003] The existing inspection wells are located on the wall surface of the pipe connection with multiple through holes with a diameter of 5-20mm. The through holes can be used in the drainage system. Groundwater can enter the well through the through holes to reduce groundwater pressure and prevent the well body from floating. When water is stored in the inspection well in winter, the water can seep into the ground from the small holes to prevent the internal water from condensing into ice too quickly and bursting the inspection well, thereby achieving an anti-freeze effect. However, the through holes are easily blocked by garbage in the sewage during long-term use, and manual entry into the inspection well is required for cleaning to avoid affecting its anti-freeze effect in winter.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an antifreeze type inspection well is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an antifreeze type inspection well to solve the above problems.

[0006] The purpose and effect of the antifreeze inspection well of the utility model are achieved by the following specific technical means:

[0007] A freeze-proof inspection well comprises an inspection well, wherein a plurality of first through holes are provided in a ring shape on the outer wall surface of the inspection well, a preparatory drainage component is installed in the inner cavity of the inspection well, and a shielding drive component matching the preparatory drainage component is installed in the inner cavity of the inspection well.

[0008] The preparatory drainage assembly includes a plurality of second through holes formed in a ring shape on the outer wall of the inspection well, an annular groove is formed on the inner wall of the inspection well at the second through holes, a number of arc-shaped blocks matching the second through holes are slidably provided in the annular groove, and an L-shaped connecting rod is fixedly installed on the rear wall of the arc-shaped block.

[0009] Furthermore, the shielding drive assembly includes a first annular block fixedly mounted on the inner wall of the inspection well, and the first annular block is located above the second through hole, an annular groove is provided on the bottom surface of the first annular block, a gear ring is installed in the annular groove, a second annular block is installed on the bottom surface of the gear ring, and the bottom surface of the second annular block is fixedly connected to the upper end of the L-shaped connecting rod.

[0010] Furthermore, the shielding drive assembly also includes an arc groove installed on the top surface of the first annular block, and an arc cavity connected to the annular groove of the first annular block is opened in the middle of the arc groove. A gear is rotatably installed in the arc cavity, and the gear is meshed with the ring gear.

[0011] Furthermore, a rotating shaft is fixedly mounted at the middle of the front end of the gear, and the rotating shaft is located at the outer wall surface of the arc groove.

[0012] Furthermore, the wall surfaces at both ends of the arc-shaped stopper are arranged to be inclined inwards.

[0013] Furthermore, the length of the outer arc surface of the arc-shaped stopper is smaller than the distance between two adjacent second through holes.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the winter, when the utility model is used, the staff opens the manhole cover of the inspection well, and drives the gear in the arc groove to rotate by rotating the rotating shaft rod, drives the gear ring meshing with the gear to rotate, and then drives the L-shaped connecting rod on the second annular block at the lower end of the gear ring to rotate, drives the arc stopper to rotate, and the arc stopper rotates away from the blocked second through hole. When the arc stopper rotates to between two adjacent second through holes, the manhole cover can be closed. When the first through hole is blocked by garbage in the sewage, the sewage seeps into the ground through the second through hole, avoiding the internal water condensing into ice too quickly and bursting the inspection well, thereby achieving the anti-freezing effect. The staff does not need to enter the inspection well specifically to clean it in winter.

[0016] 2. The two ends of the arc-shaped stopper in the utility model are inclined inward, so when garbage in sewage adheres to the inner wall of the annular groove, the arc-shaped stopper can slide to remove the sewage garbage on the inner wall of the annular groove through its two ends, making it easier to rotate with the rotating shaft rod and avoiding the need for manual cleaning.
