The net structure is prone to sagging and reducing in height, and is easily damaged, so it cannot effectively intercept wind sand for a long time. Especially in strong winds, the vertical single-layer net is easily blown down or damaged, and cannot continue to be used. In strong winds, it cannot effectively prevent sand, and after the strong winds, it cannot continue to be used due to damage, and needs to be re-laid. When the positioning pile is broken or tilted, it also needs to be re-fixed, and after the old single-layer net is removed, the new net needs to be laid and installed.

[0025] In use, the two bottom plates 101 are oppositely fixed on the sand ground, on the same side, the first filter plate 102 and the second filter plate 103 can be in a parallel state, so that the sand prevention assembly 1 as a whole presents a triangular prism shape, at this time, the sand prevention height is higher, the second filter plate 103 and the first filter plate 102 adopt the form of upper sparse and lower dense, the second filter plate 103 located on the upper side has a lower mesh number and a stronger ventilation capacity, can intercept large-diameter sand particles or flying sundries, and the first filter plate 102 has a higher mesh number and can effectively intercept sand dust and reduce the migration of sand soil.

[0026] When strong wind weather is predicted, the height of the sand prevention assembly 1 is lowered in advance to reduce losses. The first filter plates 102 on both sides are rotated outward to be close to the sand ground surface, and the two second filter plates 103 are lowered in height. Through the selection of the hinged structure, the two first filter plates 102 can be abutted on the ground and directly press the sand ground, at this time, the sand prevention assembly 1 as a whole presents a lower triangular prism structure; an acute angle can exist between the outer side surface of the first filter plate 102 and the ground, the sand ground surface is regarded as a whole as a plane, at this time, a certain space exists between the first filter plate 102 and the ground, which can accommodate a part of sand particles and reduce the movement of the sand particles.

The positioning of the first filter plate 102 after being rotated can rely on existing conventional technologies, such as bolt clamping, bolt positioning, etc. After the first filter plate 102 is fixed, the two second filter plates 103 form a stable triangular structure.

[0027] The first filter plate 102 and the second filter plate 103 face the main wind direction, or depend on the demand for preventing the migration of sand soil, and can be installed according to actual conditions. A plurality of sand prevention assemblies 1 can be arranged in sequence and closely to form a large-area sand prevention on the whole surface.

[0032] The pressing plate 201 can be a frame structure, that is, the middle part is provided with an avoiding opening 2011, which can expose the breeding window 3 while pressing the bottom plate 101, and the sand protection plants are in the breeding window 3. The pressing plate 201 can be provided with an anchor 202 at each of the four corners, and the bottom plate 101 can be provided with a hole position at a position opposite to the hole position, the hole position can be connected in communication with the groove 1011, and the anchor 202 can be inserted into the hole position, so that the two bottom plates 101 are relatively fixed.

[0033] When a plurality of sand blocking assemblies 1 are closely arranged, the protection spaces 4 are connected in sequence.

[0034] Further, the sand blocking assembly 1 has a plurality of sand blocking assemblies 1, the plurality of sand blocking assemblies 1 are arranged in sequence, and the plurality of protection spaces 4 are arranged opposite to each other. The plurality of sand blocking assemblies 1 are arranged in sequence and are spaced apart. Further, the sand blocking assembly 1 has a plurality of sand blocking assemblies 1, the plurality of sand blocking assemblies 1 are arranged in sequence, and the plurality of protection spaces 4 are arranged opposite to each other. The plurality of sand blocking assemblies 1 are arranged in sequence and are spaced apart.

The sand blocking assemblies 1 serve as internal supports of the sand blocking net 5 and play a supporting and positioning role for the sand blocking net 5. Meanwhile, when the sand blocking assemblies 1 are converted between the high and low positions, the triangular structure and the pentagonal structure are converted, and the sand blocking net 5 is converted accordingly. The sand blocking net 5 can be bound to the first filter plate 102 or the second filter plate 103 by binding wires or the like to enhance stability.

[0037] After the sand blocking net 5 is arranged, the plurality of protective spaces 4 form a mutual communication structure, and breeding can be carried out inside the sand blocking net 5.

In addition to serving as an internal support of the sand blocking net 5, the sand blocking assembly 1 can also be used to repair the sand blocking net 5. When the sand blocking net 5 has local damage, a sand blocking assembly 1 can be added inside or the adjacent sand blocking assembly 1 can be moved to the damaged part. The sand blocking net 5 near the damaged part can be bound and fixed to the first filter plate 102 or the second filter plate 103 of the sand blocking assembly 1 by binding wires or the like, thereby achieving the effect of repairing the damage and enabling the sand blocking net 5 to continue to be used. Compared with the conventional mending measures, the sand blocking assembly 1 is more stable and has a longer service life.

[0040] When there are plants inside the sand blocking net, a sand blocking assembly 1 can also be temporarily added. In the sand blocking assembly 1, the two bottom plates 101 are in a separated structure and can be installed from both sides of the plants, which is convenient for repairing and installing.

[0041] Further, the sand blocking assembly 1 further comprises a connecting rod 6 that sequentially penetrates the plurality of sand blocking assemblies 1 and is used to drive all the first filter plates 102 to rotate.

[0042] In use, the height adjustment of the plurality of sand blocking assemblies 1 can be synchronously controlled by setting the connecting rod 6, and the positioning of the sand blocking assemblies 1 is strengthened, the end of the connecting rod 6 can be additionally fixed by a support, etc., so as to strengthen the positioning of the sand blocking assemblies 1.
