DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Example 1
[0024] like Figures 1-4 As shown, a drainage protection fence includes a chassis 1, a plurality of support pads 2 are installed at the bottom of the chassis 1, a fixing mechanism 3 is installed inside the chassis 1, and a protection mechanism 4 is installed on the top of the chassis 1.
[0025] As shown Figure 2 and Figure 3 As shown, it is further obtained that the fixing mechanism 3 includes a hanger 5, a cross bar 6 and a fixed rod 10. The hanger 5 is fixedly installed at the bottom of the chassis 1, and the cross bar 6 and the fixed rod 10 are fixed inside the hanger 5. The middle part of the cross bar 6 and the fixed rod 10 is fixedly installed with a vertical rod 7, and a rotating rod 8 is movably installed inside the vertical rod 7. The top of the rotating rod 8 is installed with a rocker 9, and two adjusting rods 11 are movably installed inside the cross bar 6. Guide rods 12 are installed on the outside of the two adjusting rods 11, which pass through both ends of the cross bar 6 and are respectively sleeved on the outside of the two adjusting rods 11. The inner ends of the two adjusting rods 11 and the bottom end of the rotating rod 8 are installed with bevel teeth 13.
[0026] The top view of the chassis 1 is in a circular ring shape, and the diameter of the top of the hanger 5 is larger than the diameter of the bottom. The hanger 5 is used to be clamped in the wellhead of the drainage well to position the chassis 1 on the drainage wellhead.
[0027] The threads on the outer periphery of the two adjusting rods 11 have the same direction. The bevel teeth 13 at the inner end of the adjusting rod 11 are meshed with the bevel teeth 13 at the bottom end of the rotating rod 8. Through the meshing of the bevel teeth 13, the rotating rod 8 drives the adjusting rod 11 to rotate.
[0028] The guide rod 12 passes through the outer end of the cross bar 6 and is slidable inward and outward, and is threadedly connected to the adjusting rod 11. The adjusting rod 11 rotates and drives the guide rod 12 to slide inward and outward under the action of the thread, so that the hanger 5 is fixed in the drainage wellhead.
[0029] Specifically, by placing the chassis 1 at the drainage well mouth, the hanger 5 is located in the drainage well mouth, and the shaking plate 9 is shaken to make the rotating rod 8 drive the two adjusting rods 11 to rotate, and the guide rod 12 slides inward and outward under the action of the thread, so that the outer end of the guide rod 12 contacts the drainage well mouth and presses to fix it, so as to adapt to drainage well mouths of different diameters.
[0030] Example 2
[0031] like Figure 4 As shown, based on the first embodiment, the protective mechanism 4 further includes a protective fence 14 and a screw sleeve 15, the screw sleeve 15 is fixedly installed on the top of the chassis 1, and a screw ring 16 is fixedly installed on the bottom end of the protective fence 14, and the outer ring of the screw ring 16 is provided with a threaded groove 17.
[0032] The guardrail 14 is arranged in a cylindrical grid shape. The height of the guardrail 14 is higher than the height of the vertical rod 7. By installing the guardrail 14, the protection at the drainage wellhead is improved.
[0033] The screw ring 16 is threadedly connected to the inner ring of the screw sleeve 15 through the screw groove 17, and the guardrail 14 is threadedly connected to the top of the chassis 1, which facilitates the installation and removal of the guardrail 14.
[0034] Specifically, the guardrail 14 is installed on the top of the chassis 1, and the screw ring 16 is connected to the screw sleeve 15 through the threaded groove 17. The top of the guardrail 14 is used to place the drainage manhole cover, and the guardrail 14 provides protection.
[0035] During actual operation, the chassis 1 and the hanger 5 are placed at the drainage well mouth, and the guardrail 14 is used to provide protection, so that water can flow in and out quickly and prevent pedestrians and debris from falling in;
[0036] When fixing, the oscillating plate 9 is shaken to rotate the rotating rod 8, and the two adjusting rods 11 are rotated simultaneously under the meshing action of the bevel teeth 13. The guide rod 12 slides inward and outward through the thread, so that the outer end of the guide rod 12 contacts and presses against the inner wall of the drainage well, thereby fixing the hanger 5 and the base plate 1 to the drainage well.
[0037] During protection, the guardrail 14 is fixed to the top of the chassis 1 through the threaded connection between the screw ring 16 and the screw sleeve 15. The top of the guardrail 14 is used to place the drainage manhole cover. The guardrail 14 provides protection for the drainage manhole mouth to prevent pedestrians and debris from falling in, so as to be suitable for the drainage of larger floods in the municipality.
[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
