DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Reference Figure 1-3The utility model provides an embodiment: a municipal manhole cover structure, including a cylinder 1, a manhole cover 2 is sleeved on the top of the cylinder 1, a filtering mechanism is sleeved on the top of the manhole cover 2, and a buffer mechanism is arranged at the connection between the manhole cover 2 and the cylinder 1; the filtering mechanism includes a large filter frame 3 and a large filter screen 4, the large filter frame 3 is sleeved on the top of the large filter screen 4, a cross pull rod 5 is fixedly arranged on the top of the large filter screen 4, a plurality of connecting rods 6 are fixedly arranged on the outside of the large filter frame 3, a plurality of small filter frames 7 are fixedly arranged on one end of the connecting rod 6, a small filter screen 8 is fixedly arranged inside the small filter frame 7, a docking groove 9 is sleeved on the outside of the large filter frame 3, an anti-slip pad 10 is fixedly arranged inside the docking groove 9, a connecting groove 11 is sleeved on the outside of the connecting rod 6, and a filter groove 12 is sleeved on the outside of the small filter frame 7.
[0028] The sewage flowing into the docking groove 9 and the filter groove 12 is filtered by the large filter mesh 4 and the small filter mesh 8, thereby preventing debris from flowing into the docking groove 9 and the filter groove 12 and entering the sewer pipe to cause blockage. When cleaning, it is only necessary to manually lift the cross pull rod 5 to drive the connecting rod 6, the large filter frame 3 and the small filter frame 7 to simultaneously detach from the connecting groove 11, the docking groove 9 and the filter groove 12, so as to facilitate the cleaning of the large filter mesh 4 and the small filter mesh 8, and also make it easier to install and disassemble the large filter frame 3 and the small filter frame 7 and the manhole cover 2.
[0029] The buffer mechanism includes a buffer groove 13 and a shock absorber 14. The shock absorber 14 is fixedly arranged on the top of the buffer groove 13. The docking block 15 is fixedly arranged on the top of the shock absorber 14. A fixing block 16 is arranged on the top of the docking block 15. A matching screw hole 17 is penetrated at the connection between the fixing block 16 and the docking block 15. The internal thread sleeve of the screw hole 17 is provided with a stud 18.
[0030] By fixing the studs 18 and the screw holes 17, the manhole cover 2 is fixed inside the cylinder 1 with the cooperation of the fixing block 16. When vehicles repeatedly pass over the manhole cover 2, the manhole cover 2 is pressed down under the impact of gravity, and the pressure will be transmitted to the shock absorber 14 through the fixing block 16 and the docking block 15. The shock absorber 14 absorbs the vibration and impact brought by the manhole cover 2, further reducing the fatigue damage caused by the impact on the manhole cover 2.
[0031] The number of the fixing blocks 16 is four. The fixing blocks 16 are fixedly arranged on the outside of the manhole cover 2 . The buffer groove 13 is penetrated and arranged on the top surface of the cylinder body 1 .
[0032] By fixing the block and inserting it into the buffer groove 13, the manhole cover 2 can be prevented from displacement and rotation.
[0033] The docking groove 9 , the connecting groove 11 and the filtering groove 12 are connected through each other, and the docking groove 9 , the connecting groove 11 and the filtering groove 12 all penetrate to the top surface of the manhole cover 2 .
[0034] The connecting rod 6, the large filter frame 3 and the small filter frame 7 can be fixed inside the manhole cover 2 through the docking groove 9, the connecting groove 11 and the filter groove 12, so that they are flush with the top of the manhole cover 2 to avoid affecting pedestrians.
[0035] A docking ring 19 is disposed inside the cylinder 1 , and a plurality of support plates 20 are fixedly disposed outside the docking ring 19 . The other ends of the support plates 20 are fixedly connected to the inner wall of the cylinder 1 .
[0036] By supporting the bottom of the manhole cover 2 by the support plate 20 , the structural strength between the manhole cover 2 and the cylinder body 1 can be strengthened to avoid deformation between the manhole cover 2 and the cylinder body 1 .
[0037] The anti-skid pad 10 abuts against the bottom of the large filter frame 3 , and the bottom of the well cover 2 abuts against the support plate 20 .
[0038] The anti-skid pad 10 can ensure that when the large filter frame 3 moves downward under pressure, the bottom of the large filter frame 3 contacts the anti-skid pad 10 to provide a certain buffering effect.
[0039] Working principle: First, install the manhole cover 2 structure at the drainage position, so that the manhole cover 2 is flush with the ground, and the manhole cover 2 is fixed inside the cylinder 1 with the cooperation of the fixing block 16 through the threaded connection between the stud 18 and the screw hole 17; when it rains, rainwater is drained through the docking groove 9 and the filter groove 12. During the drainage process, the large filter screen 4 and the small filter screen 8 will filter the sewage flowing into the docking groove 9 and the filter groove 12, avoiding the situation where debris flows into the docking groove 9 and the filter groove 12 and enters the sewer pipe to cause blockage. When cleaning, you only need to manually lift the cross pull rod 5 to drive the connecting rod 6 and the large filter frame 3 The connecting groove 11, the docking groove 9 and the filter groove 12 are separated from the small filter frame 7 at the same time, so as to facilitate the cleaning, installation and disassembly of the large filter screen 4 and the small filter screen 8; when the vehicle repeatedly passes over the manhole cover 2, the manhole cover 2 is pressed down under the impact of gravity, and the pressure will be transmitted to the shock absorber 14 through the fixing block 16 and the docking block 15. The shock absorber 14 absorbs the vibration and impact brought by the manhole cover 2, further reducing the fatigue damage caused by the impact on the manhole cover 2. At the same time, the support plate 20 is used to support the bottom of the manhole cover 2, which can strengthen the structural strength between the manhole cover 2 and the cylinder 1, and avoid deformation between the manhole cover 2 and the cylinder 1.
[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
