It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0023] Example: Figures 1-4As shown, the utility model provides a technical solution, an anti-clogging manhole cover that is easy to clean, comprising a manhole cover center circle 1, a manhole cover ring edge 2 is fixedly installed on the edge of the manhole cover center circle 1, a keyhole 3 is opened at one end of the manhole cover center circle 1, threaded holes 4 are opened equidistantly along the circumferential direction at the bottom end edge of the manhole cover center circle 1, a mounting ring plate 5 is fixedly installed on the bottom end edge of the manhole cover center circle 1, locking bolts 6 are equidistantly installed on the bottom of the mounting ring plate 5 along the circumferential direction, the number of the locking bolts 6 and the threaded holes 4 is the same, and the top of the locking bolts 6 passes through the mounting ring plate 5, The manhole cover is provided with a plurality of screw holes 14, and the plurality of screw holes 14 are connected to the manhole cover by screw threads 14. The plurality of screw holes 14 are connected to the manhole cover by screw threads 14. The plurality of screw holes 14 are connected to the manhole cover by screw threads 14. The plurality of screw holes 14 are connected to the manhole cover by screw threads 14. The plurality of screw holes 14 are connected to the manhole cover by screw threads 14. The filter net bag 10 is suspended under the fixing ring 8 by a hanging hook 9, and the hanging hook 9 is suspended between two adjacent connecting short rods 7. A counterweight ring plate 11 is fixedly installed on the bottom edge of the filter net bag 10. By using the connecting short rod 7, the hanging hook 9 is limited, so that the hanging hooks 9 are placed more evenly, and the hanging hooks 9 are prevented from being piled up and unevenly placed, resulting in the incomplete unfolding of the filter net bag 10, which affects the normal collection of impurities. The counterweight ring plate 11 counterweights the bottom of the filter net bag 10, and when there are no impurities inside the filter net bag 10, it will not be arbitrarily The mounting ring plate 5 and the fixing ring 8 are installed below the center circle 1 of the manhole cover by means of the locking bolts 6 and the threaded holes 4, and the filter net bag 10 can be suspended on the fixing ring 8 by means of the hanging hooks 9. The filter net bag 10 plays a role of filtering and intercepting, filtering and intercepting rainwater falling from the keyhole 3, so that the fallen leaves and other debris washed by the rainwater will not flow into the pipe below with the water, preventing the fallen leaves from flowing into the pipe and causing the pipe to be blocked. The filter net bag 10 is installed by hanging, and the installation and taking are easy, which is convenient for subsequent cleaning.
[0024] The bottom end of the manhole cover ring 2 is equidistantly provided with positioning holes 12 along the circumferential direction. A buffer pad 13 is fitted and installed at the bottom end of the manhole cover ring 2. The top end of the buffer pad 13 is fixedly connected with positioning rubber columns 14 equidistantly along the circumferential direction. The positioning holes 12 and the positioning rubber columns 14 correspond to each other one by one. The positioning rubber columns 14 are embedded inside the positioning holes 12. The diameter of the cross-section of the positioning rubber column 14 is 0.2 mm larger than the diameter of the positioning hole 12. By using the cooperation of the positioning holes 12 and the positioning rubber columns 14, the buffer pad 13 is fitted and installed. The positioning rubber column 14 is soft in texture and its diameter is slightly larger than that of the positioning hole 12. After it is inserted into the positioning hole 12, it will deform, so that the buffer pad 13 is installed more stably and will not fall off. The buffer pad 13 buffers and protects the bottom of the manhole cover, so that when people step on the top of the manhole cover, it will not cause the bottom end of the manhole cover to collide with other positions, generating noise and shaking.
[0025] The working principle and usage process of the present utility model are as follows: First, the staff aligns the locking bolt 6 with the threaded hole 4 and tightens it to fix the mounting ring plate 5 at the bottom of the manhole cover center circle 1. The staff takes the filter net bag 10 and places it under the manhole cover center circle 1, and the hanging hooks 9 are hooked on the surface of the fixing ring 8 in turn. Each hanging hook 9 is located at the middle position between two adjacent connecting short rods 7, so that the hanging hooks 9 are more evenly distributed, that is, the filter net bag 10 unfolds more thoroughly. Then, the buffer pad 13 is taken and fitted to the bottom of the manhole cover ring 2. The positioning rubber column 14 is inserted into the inside of the positioning hole 12. The diameter of the positioning rubber column 14 is larger than the diameter of the positioning hole 12. When the positioning rubber column 14 is inserted, it will deform and be extruded, so that the buffer pad 13 is installed and fitted more stably.
[0026] The staff places the whole manhole cover at the predetermined installation position. The buffer pad 13 will be in contact with the surface of the installation position. The top of the manhole cover is flush with the ground. When people walk on the top of the manhole cover, the buffer pad 13 plays a role of buffering and protecting, so that the bottom end of the manhole cover will not collide with other positions, causing noise and shaking. The counterweight ring plate 11 weights and positions the bottom of the filter net bag 10, so that it remains stable after being placed and will not shake randomly. During rainy days, rainwater or sewage for flushing and cleaning the ground will flow down through the keyhole 3 of the manhole cover. The water passes through the keyhole 3 and falls into the inside of the filter net bag 10. The filter net bag 10 plays a role of filtering and intercepting, intercepting impurities such as fallen leaves in the water flow. The water passes through and continues to flow, preventing the pipeline below from being blocked. And it is necessary to clean the filter net bag 10 regularly. Lift the whole manhole cover, remove the hanging hooks 9 and the filter net bag 10, and remove the fallen leaves and the like inside it.
[0027] Finally, it should be noted that the above are only preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
