[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example

[0019] like Figure 1 As shown, Figure 1 Shown is an overall schematic diagram of the steel grating in the embodiment;

[0020] The device includes:

[0021] The two guard plate units are assembled and used, and the guard plate unit includes a fixed frame 10 and a movable plate 20. The movable plate 20 is arranged on the inner side of the fixed frame 10. Springs 22 are provided at both ends of the movable plate 20 along its length direction. The other ends of the springs 22 are respectively connected to the fixed frames 10 at their ends. A clearance opening 21 is opened at the ends of the two movable plates 20 that are close to each other. The deformation of the springs 22 can change the position of the movable plate 20 in its length direction, that is, change the position of the clearance opening 21.

[0022] Specifically, when protecting a tree, two guard plate units are assembled and installed in the tree pit, and the tree is located in the opening 21 where the two movable plates 20 are assembled, as shown in FIG. Figure 1As shown, the direction shown by the Y-axis is the length direction of the movable plate 20. Two springs 22 are provided at each end of the movable plate 20 in the Y-axis direction. By applying external force to the movable plate 20, the movable plate 20 can squeeze or stretch the spring 22 to change the installation position of the movable plate 20, so that trees with position offset in the length direction of the movable plate 20 can be installed and protected, thereby increasing the flexibility and practicality of the tree protection steel grating.

[0023] The movable plate 20 is also provided with a plurality of water seepage holes 24;

[0024] The fixing frame 10 is provided with a plurality of water seepage holes 11;

[0025] Rainwater can be absorbed by the tree roots through the first seepage hole 24 and the second seepage hole 11. The surface of the spring 22 is sprayed with an anti-rust coating to prevent the rainwater from corroding the surface of the spring 22.

[0026] like Figure 1 、 Figure 2 As shown, Figure 1 Shown is an overall schematic diagram of the steel grating in the embodiment; Figure 2 Shown is a schematic cross-sectional view of a steel grating in an embodiment;

[0027] The movable plate 20 is further provided with guide posts 23 at both ends along its length direction. A slot 101 is provided on the fixed frame 10 at a position corresponding to the guide posts 23. A section of the guide post 23 away from the movable plate 20 is movable and extends into the slot 101 and slidably engages with the slot 101.

[0028] By providing the guide post 23 to cooperate with the slot 101 , the stability of the connection between the movable plate 20 and the fixed frame 10 is increased, and within the range of movement of the movable plate 20 , the guide post 23 will not be separated from the slot 101 that cooperates therewith.

[0029] Auxiliary holes 12 are provided at the four corners of the assembled fixing frame 10;

[0030] The auxiliary holes 12 can be used to insert support rods for supporting trees, thereby playing an auxiliary protective role.

[0031] like Figure 3 As shown, Figure 3 The figure shows a schematic diagram of the tapered inverted teeth of the steel grating in the embodiment;

[0032] A plurality of conical inverted teeth 13 are evenly distributed on the bottom of the guard plate unit.

[0033] Specifically, the conical inverted teeth 13 are evenly distributed at the bottom of the fixed frame 10 and the movable plate 20. After the guard plate unit is spliced, the conical inverted teeth 13 are inserted into the ground by external force to fix the installation positions of the fixed frame 10 and the movable plate 20.

[0034] Working principle: When protecting trees, two guard plate units are assembled and installed in the tree pit. The tree is located in the makeshift opening 21 where the two movable plates 20 are assembled. By applying external force to the movable plate 20, the movable plate 20 can squeeze or stretch the spring 22 to change the installation position of the movable plate 20. This allows the installation and protection of trees that are offset in the length direction of the movable plate 20, thereby increasing the flexibility and practicality of the tree protection steel grating.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
