Abstract
Description
Technical Field
[0001] The utility model relates to the field of sand land management, in particular to a permeable gauze sand barrier used for desertification management. Background Art
[0002] Sand barriers, also known as mechanical sand barriers and wind barriers, are barriers made on the sand surface with firewood, straw, clay, branches, laths, pebbles and other materials. They are effective engineering sand fixation measures to reduce wind speed and fix the sand surface.
[0003] According to the patent announcement number CN204898639U, a permeable gauze sand barrier is made of single wing-shaped gauze buried 10-15 cm underground, connected end to end, and each wing-shaped gauze is folded along the short side center axis of a rectangular gauze, the mesh size of the rectangular gauze is 10-20 meshes, the width of the rectangular gauze is 50-60 cm, and the length is 50-100 m. The laying form of the grid-shaped or strip-shaped permeable gauze sand barrier is designed. When laying, spread the gauze flat on the pre-marked line, and use a rectangular flat-bottomed shovel to press down on the center of the gauze to a depth of 10-15cm, so that the two ends of the flat mesh are lifted up and upright to form a sand barrier with a height of about 10cm, which can effectively reduce the depth of the wind erosion concave surface between the sand barriers. Compared with the existing technology, this device can only accumulate sand on the sand barrier and reduce the depth of the wind erosion concave surface between the sand barriers. It is not easy to replace the sand barrier itself. The sand barrier is exposed to wind and sand for a long time. If the gauze is damaged, the entire gauze must be replaced or the damaged area must be repaired. The replacement and repair process takes a long time and is likely to cause the accumulated sand to be blown away, which consumes a lot of manpower and is more troublesome.
[0004] Therefore, there is an urgent need to design a permeable gauze sand barrier for desertification control that is easy to replace and disassemble. Utility Model Content
[0005] In order to overcome the shortcomings of existing sand barriers, the utility model provides a permeable gauze sand barrier for desertification control which is easy to replace and disassemble.
[0006] In order to solve the above technical problems, the utility model provides a permeable gauze sand barrier for desertification control, comprising a sand barrier rod, a connecting block, a guide rod, a fixed block, a spring and a gauze net, the sand barrier rod being a carrier for installing device components, the connecting block being fixedly installed on the upper and lower parts of the sand barrier rod, the guide rod being fixedly installed on the front and rear sides of the connecting block, the fixed block being slidably installed on the guide rod, the spring being installed between the fixed block and the connecting block, and the gauze net being clamped between the fixed block and the connecting block on the same side.
[0007] Preferably, a limiting block for preventing the fixing block from sliding out is provided at the end of the guide rod.
[0008] Preferably, it also includes stabilizing blocks which are evenly spaced and installed on the outer side of the lower part of the sand barrier pole.
[0009] Preferably, it also includes a ring installed on the lower part of the sand barrier rod by bolts; a hollow rod fixedly connected in the ring; an insertion rod slidably installed inside the hollow rod, and the bottom end of the insertion rod is conical; and a card ball evenly installed on the inner wall of the insertion rod.
[0010] Preferably, the locking ball is made of rubber, and the inner side of the locking ball has a certain friction force against the insertion rod.
[0011] Preferably, there are two gauze meshes installed on the front and rear sides of the sand barrier pole, and the mesh sizes of the gauze meshes on the two sides are different.
[0012] Preferably, the stabilizing block is arranged in an inverted triangle shape.
[0013] 1. The fixing block and spring of the utility model stretch the fixing block and drive the spring at the same time. When the fixing block is loosened, the spring drives the fixing block to reset and clamp the gauze. If the gauze is to be taken out, the fixing block is directly pulled back, thus avoiding the problem that the gauze is difficult to replace and disassemble.
[0014] 2. The plugging rod and the card ball of the utility model are used to pull the plugging rod in the hollow rod, and the card ball inside is in a squeezed state, and then it is pulled down to a required height, so that it is convenient to extend and bury it in deeper sand.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] Embodiment: A permeable gauze sand barrier for desertification control, such as Figure 1-Figure 3 As shown, it includes a sand barrier rod 1, a connecting block 2, a guide rod 3, a fixing block 4, a spring 5 and a gauze 6. The sand barrier rod 1 is a carrier for installing the device components. The upper part of the sand barrier rod 1 is spherical and arranged on both sides for easy hand grasping. The connecting block 2 is installed on the upper and lower parts of the sand barrier rod 1 by bolts, and the front and rear sides are also connected to clamp the gauze 6 and prevent it from falling off. The guide rod 3 is fixedly installed on the front and rear sides of the connecting block 2, and the fixing block 4 is installed on the guide rod 3 by sliding connection. The fixing block 4 and the guide rod 3 are on the side of the connecting block 2 away from each other, and there is a certain distance between the connecting block 2 and the fixing block 4. The spring 5 is installed between the fixing block 4 and the connecting block 2. The gauze 6 is arranged in a square shape, and the gauze 6 is clamped between the fixing block 4 and the connecting block 2 on the same side. There are two gauze nets 6, which are installed on the front and rear sides of the sand barrier rod 1, and the mesh sizes of the gauze nets 6 on both sides are different.
[0023] like Figure 4 and Figure 5 As shown, it also includes a stabilizing block 7, a circular ring 8, a hollow rod 9, an inserting rod 10 and a locking ball 11. The stabilizing block 7 is evenly installed on the outer side of the lower part of the sand barrier rod 1. The stabilizing block 7 is provided with at least two inverted triangles for stabilizing the foundation of sand fixation. The circular ring 8 is installed on the lower part of the sand barrier rod 1 by bolts. The hollow rod 9 is fixedly connected in the circular ring 8.

The length of the inserting rod 10 is longer than that of the hollow rod 9. There are at least two locking balls 11, which are evenly installed on the inner wall of the inserting rod.
[0024] When using the device, first stretch the fixing block 4 to the side away from the connecting block 2, at this time, the spring 5 is stretched, and the gauze 6 is placed at the angle between the connecting block 2 and the fixing block 4, and the fixing block 4 is released. The spring 5 drives the fixing block 4 to reset and clamp, and the above operation is repeated to clamp the four corners of the gauze 6. If the gauze 6 needs to be taken out, the fixing block 4 is directly pulled back to take out the gauze 6. If the sand barrier needs to be buried deeper in the sand, the insertion rod 10 in the hollow rod is pulled. At this time, the internal The card ball 11 is in an extruded state, and then pulled down to the required height, the internal card ball 11 will be exposed on the surface and in a protruding state against the hollow rod, and then inserted into the sand to fix the stabilizing block 7 on the sand barrier rod 1, and take root in the sand and is not easy to pull out, thereby achieving the purpose of sand fixation. After use, first take out the gauze 6 from the sand, and then pull the inserted rod 10 in the hollow rod 9 upward, the protruding card ball 11 is squeezed and retracted, and the fixing blocks 4 at the four corners are loosened to loosen the gauze 6 and remove it.
