[0018] Working principle: In this embodiment, the present invention also proposes a use method of a composite resin manhole cover with a reinforcing structure, including the following steps: Step 1, first install and fix the support seat 1 on the water pipeline. The convex block at the side end of the support seat 1 can better seal the cement to fix the support seat 1. Then connect the retaining frame 7 and the support plate 21 and set a retaining net in the retaining frame 7. The connecting block 20 at the upper part of the retaining frame 7 is clamped with the hook 24 at the lower part of the support plate 21. The limit bolt 19 arranged on a connecting block 20 at the upper part of the retaining frame 7 is fixed in cooperation with the limit hole 25. The arrangement of the limit hole 25, the connecting block 20 and the hook 24 can not only facilitate the disassembly of the retaining frame 7, but also improve the connection strength of the retaining frame 7. When disassembling the retaining frame 7, just remove the hook 24 and rotate the retaining frame 7 with the limit bolt 19 at the limit hole 25 as the center. Step 2, then place a buffer pad 17 in the slot of the support seat 1. Then fit and install the support plate 21 with the retaining frame 7 on the buffer pad 17 in the slot of the support seat 1. Then place the filter plate 6 in the horizontal slot of the cover plate 2. The convex strips at the edge of the filter plate 6 abut against and support the upper and lower ends of the horizontal slot of the cover plate 2. Then install the hinge rod 13 at the rear end of the cover plate 2 in cooperation with the hinge seat 4. Then fix the hinge block 5 to the hinge seat 4. A limit bolt 19 is arranged on the hinge block 5, and a special notch is formed at the upper part of the limit bolt 19. The special notch can prevent personnel from using non-professional tools to disassemble the cover plate 2. Step 3: Subsequently, install the fixing mechanism 3 in the installation groove 15 of the support base 1. The protruding limit block 9 on the fixing mechanism 3 is engaged and fixed with the limit groove 12 on the cover plate 2. The spring 18 on the fixing mechanism 3 can eject the limit block 9 so that the limit block 9 is engaged and clamped with the limit groove 12. A connecting plate facilitating the sliding of the limit block 9 is arranged at the rear end of the limit block 9. A baffle 8 is arranged on the fixing mechanism 3. A limit bolt 19 is installed at the front end of the baffle 8 and the installation groove 15. The baffle 8 can block sundries from entering the fixing mechanism 3 and prevent the fixing mechanism 3 from jamming. Step 4: The lower end of the cover plate 2 is provided with reinforcing bars 14 evenly distributed horizontally and vertically. The arrangement of the reinforcing bars 14 can better enhance the strength of the cover plate 2, thus better facilitating the people walking on the manhole cover and the vehicles passing by. A support block 23 protrudes from the upper part of the support plate 21. The support block 23 abuts against the reinforcing bar 14 at the lower part of the cover plate 2. The support block 23 arranged on the support plate 21 can strengthen the support of the middle part of the cover plate 2, increase the bearing capacity of the middle part of the cover plate 2, avoid the use of a circular manhole cover with a sunken middle part of the cover plate 2, and thus enhance the service life of the manhole cover. Step 5: Finally, when the manhole cover is disassembled and repaired, the limit bolt 19 needs to be removed with a special tool, the baffle 8 in the installation groove 15 is opened, the connecting plate at the rear of the limit block 9 is toggled to release the clamping of the cover plate 2, and then the hinge block 5 and the cover plate 2 are removed. The filter plate 6 in the cover plate 2 can be disassembled for replacement and maintenance. Then, the support plate 21 with the retaining frame 7 is taken out, the three hooks 24 are removed, and the retaining frame 7 is rotated to replace the filter screen in the retaining frame 7. The buffer pad 17 at the lower part of the support plate 21 can enhance the shock absorption capacity of the manhole cover and avoid the reduction of the service life of the manhole cover due to impact loads. Thus, the installation and use of the manhole cover are completed.
[0019] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
