[0003] In the prior art, in order to solve the problem of the movement of mobile sand dunes, measures such as grass grids, stone grids, clay grids and chemical sand fixation have been proposed. However, the above measures generally have the problems of low construction efficiency, short service life, high comprehensive cost, and limited raw materials, and the sand fixation effect is also poor. Summary of the invention

[0004] The purpose of the present invention is to provide a wind-proof and sand-fixing grid system, which is easy to construct, convenient for later operation and maintenance, and has a good sand-fixing effect.

[0005] To achieve this object, the present invention adopts the following technical solutions:

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0036] like Figures 1 to 4 As shown, the present embodiment provides a wind-proof and sand-fixing grid system, including a fixing component and a plurality of wind-proof and sand-fixing grids 1, each wind-proof and sand-fixing grid 1 includes a plurality of small grids 11 spliced ​​in sequence, and each small grid 11 is surrounded by a protective belt 111. The wind-proof and sand-fixing grid 1 is quadrilateral, and the wind-proof and sand-fixing grid 1 is provided with a fixing hole 12. The fixing component includes a cross nail 2, a U-shaped nail 3, and a 1-shaped nail 4. A plurality of wind-proof and sand-fixing grids 1 are spliced ​​in sequence, and the intersection of more than three fixing holes 12 is fixed with a cross nail 2, the intersection of two fixing holes 12 is fixed with a U-shaped nail 3, and one fixing hole 12 is fixed with a 1-shaped nail 4. The cross nail 2, the U-shaped nail 3, and the 1-shaped nail 4 all pass through the corresponding fixing holes 12 and are inserted below the sand ground. Each wind-proof and sand-fixing grid 1 is detachable. When the wind-proof and sand-fixing grid system is installed, the wind-proof and sand-fixing grids 1 are installed and spliced ​​one by one. In the later operation and maintenance stage, when a certain wind-proof and sand-fixing grid 1 is damaged, it can be disassembled and replaced separately. The assembly is simple and convenient, and the later operation and maintenance are convenient. In addition, after the installation of the wind-proof and sand-fixing grid system is completed, after a period of sedimentation, the sand in the wind-proof and sand-fixing grid 1 accumulates to a certain height, and the wind-proof and sand-fixing effect is reduced. The fixed components can be pulled out and the position height of the protective belt 111 can be adjusted to make the effective protection height of the wind-proof and sand-fixing grid 1 reach the initial height again. Alternatively, after the mobile sand dunes are converted into fixed sand dunes, the wind-proof and sand-fixing grid 1 here can also be moved to other locations for reuse.

[0037] Specifically, when installing the wind-proof and sand-fixing grid system, firstly lay out the lines to clarify the position of each wind-proof and sand-fixing grid 1; then start the installation from the upwind position, and lay multiple wind-proof and sand-fixing grids 1 in turn at the line-laying and positioning positions; then select the corresponding fixing components according to the number of fixing holes 12 at the junction, and gradually extend them downward in rows by splicing and assembling until the installation of the entire wind-proof and sand-fixing grid system is completed.

[0038] If an error occurs during the installation process, resulting in the width of the last column being inconsistent with the designed width of the wind-proof and sand-fixing grid 1, the shape of the wind-proof and sand-fixing grid 1 can be adjusted to a diamond shape to meet the width requirement. Alternatively, when the site is irregular, the shape of the wind-proof and sand-fixing grid 1 can be customized in advance to fit the site shape.

[0039] Optionally, the windbreak and sand fixation grid 1 is in a quadrilateral shape, and the quadrilateral arrangement can be beneficial to improving the sand fixation effect. Figure 1 , the windbreak and sand fixation grid 1 can be square, and accordingly, the small grid 11 is also square; or, referring to Figure 2 The wind-proof and sand-fixing grid 1 may also be in the shape of a parallelogram, and correspondingly, the small grid 11 may also be in the shape of a parallelogram; alternatively, in other embodiments, the wind-proof and sand-fixing grid 1 may also be in the shape of a rectangle or a quadrilateral of other shapes.

[0040] Specifically, the junctions of the plurality of small grids 11 may be fixed with cross nails 2 , U-shaped nails 3 or I-shaped nails 4 , as long as the plurality of small grids 11 can be spliced ​​into the windbreak and sand fixation grid 1 .

[0041] Optionally, the protection belt 111 is made of high-density polyethylene material, so that the protection belt 111 has good anti-oxidation and anti-weathering properties, thereby effectively extending the service life of the wind-proof and sand-fixing grid system.

[0042] Optionally, the side length of the small grid 11 is 1m-2m. Specifically, in this embodiment, the side length of the small grid 11 is 1m, which not only protects the sand plants from being buried by wind erosion and sand, but also prevents local sand from being blown up, and has a good sand fixation effect.

[0043] Optionally, the small grid 11 is 0.2m-0.5m high. Based on the physical principle of parabolic motion of sand particles, this height range is sufficient to block wind and sand, and allow the wind to form a rotational motion in the grid, forming a pot-shaped body with high sides and low middle, which is conducive to improving the sand fixation effect.

[0044] Optionally, refer to Figures 3 to 5 The ends of the cross nails 2, U-shaped nails 3 and I-shaped nails 4 inserted into the ground are all provided with sharp points, so that the cross nails 2, U-shaped nails 3 and I-shaped nails 4 can be smoothly inserted under the sandy ground, which is beneficial to improve the installation efficiency.

[0045] Optionally, the ends of the cross nails 2, U-shaped nails 3 and I-shaped nails 4 away from the ground are all provided with operating parts (not shown in the figure) to facilitate the operation of the operator. Specifically, the operating part is an operating handle.

[0046] Furthermore, an anti-skid structure is provided on the operating part. Specifically, the anti-skid structure is an anti-skid pad provided on the outside of the operating part, such as a rubber pad, or the anti-skid structure is an anti-skid protrusion provided on the outside of the operating part. The anti-skid protrusion can be a dot-shaped protrusion or a patterned protrusion of any shape. Its function is to increase the contact friction between the operating part and the operator's hand to facilitate operation. The specific form is referred to the prior art and is not specifically limited in this embodiment, as long as it can play a role in increasing friction.

[0047] Optionally, the cross nails 2, U-shaped nails 3 and I-shaped nails 4 are all made of alloy materials, which have the advantages of high hardness and high corrosion resistance, and can effectively improve the service life of the windbreak and sand fixation grid system.

[0048] Optionally, the protective belt 111 is provided with a plurality of meshes, which are distributed in a dot matrix. Specifically, the shape of the meshes can be circular, diamond or rectangular. The arrangement of the meshes can effectively slow down the wind speed on the slope surface and improve the sand fixation effect.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
