Description
Technical Field
[0001] The utility model relates to the technical field of grid plates, in particular to a sewer grid plate for municipal engineering. Background Technique
[0002] Municipal engineering refers to the construction project of municipal infrastructure. Municipal engineering involves the transformation of sewers. In the transformation of sewers, it is necessary to install grid plates on the sewers. Grid plates are also called steel grating plates. Due to regional differences, people in the south are used to calling them grid plates, while people in the north are used to calling them steel grating plates. Generally, they are collectively called steel grating plates. Grid plates are generally made of carbon steel and are hot-dip galvanized on the outside, which can play a role in preventing oxidation. They can also be made of stainless steel.
[0003] After the sewer is transformed, it is necessary to install grid plates on its top. Since the sizes and widths of the sewer outlets are different, it is very difficult for the front and back widths of the grid plates to fit the inner walls of the sewers. In subsequent use, it is easy to appear the phenomenon of random shaking. At the same time, the grid plates are placed row by row or column by column on the surface of the sewer. Under the action of external gravity, the corners of some grid plates are prone to warping and are prone to damage over time. Content of the Utility Model
[0004] The purpose of the utility model is to provide a sewer grid plate for municipal engineering to solve the problems existing in the above background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-5 As shown, a sewer grating plate for municipal engineering includes a grating plate body 1. A limiting plate 2 is fixedly connected to the right side of the grating plate body 1. Limiting holes 3 are provided in both the front and rear of the limiting plate 2. A limiting groove 4 is provided on the left side of the grating plate body 1. Activity grooves 5 are provided in both the front and rear of the left side of the top of the grating plate body 1. A limiting rod 6 is movably connected inside the activity groove 5. A fixing rod 7 is fixedly connected to one side of the limiting rod 6. One end of the limiting rod 6 is used in cooperation with the inside of the limiting hole 3. Fixing grooves 12 are communicated with both the front and rear of the right side of the activity groove 5. The fixing rod 7 is located inside the fixing groove 12. In this way, after the limiting rod 6 moves, the fixing rod 7 can be rotated into the inside of the fixing groove 12, thereby limiting the position of the limiting rod 6. Concave plates 8 are provided on both the front and rear sides of the grating plate body 1. The size of the concave plate 8 is larger than the wall thickness size of the grating plate body 1. The two ends of the concave plate 8 are flush with the two ends of the grating plate body 1. In this way, the concave plate 8 can be better adjusted and moved on the surface of the grating plate body 1 to facilitate subsequent installation. Screws 9 are threadedly connected to both the front and rear of the inner cavity of the grating plate body 1. And torsion disks 10 are fixed to the opposite ends of the front and rear two screws 9. The other end of the screw 9 is rotatably connected to the inside of the concave plate 8.
[0023] Activity rods 11 are movably connected to both the front and rear of both sides of the inner cavity of the grating plate body 1. One end of the activity rod 11 is fixed to the inside of the concave plate 8. In this way, the concave plate 8 can be assisted in being limited, facilitating its front and rear movement.
[0024] Clamping plates 14 are fixed to both the front and rear of the right side of the grating plate body 1. Card slots 15 are provided in both the front and rear of the left side of the grating plate body 1. The surface of the clamping plate 14 is used in cooperation with the card slot 15. In this way, when the grating plate body 1 is attached to an adjacent grating plate body 1, the clamping plate 14 can enter the inside of the card slot 15, thereby improving the stability of the splicing of the two adjacent grating plate bodies 1.
[0025] A groove 13 is provided on the right side of the inner cavity of the grating plate body 1. In this way, it is convenient for the user to apply force to the grating plate body 1 to facilitate the taking of the grating plate body 1.
[0026] It should be noted that in this technical solution, technical features such as [specific features not provided in the original] should be regarded as the prior art. For the specific structures, working principles, possible control methods, and spatial arrangement methods of these technical features, conventional selections in the art can be adopted, and this technical solution will not be further elaborated specifically.
[0027] Working principle: When in use, when installing the grid plate body 1 on the surface of the sewer, the width of the sewer can be referred to, and the torsion disc 10 can be rotated, then driving the screw rod 9 to rotate, and at the same time driving the concave plate 8 to move outward, so that the size of the grid plate body 1 increases to facilitate adaptation to sewer sizes of different widths. After the grid plate body 1 is placed, the limiting plate 2 at the grid plate body 1 can be aligned with the limiting groove 4 of another adjacent grid plate body 1. When the limiting plate 2 enters the inside of the limiting groove 4, the fixing rod 7 can be rotated upward, thus canceling the limitation on the limiting rod 6, and then the limiting rod 6 can be pushed so that the limiting rod 6 enters the inside of the limiting hole 3, thereby limiting the limiting groove 4.
