Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of desertification control grid devices, specifically a PVC grid device for desertification control. Background Technology
[0002] Windbreak and sand-fixing devices are important tools for desertification control. They effectively block sandstorms and wind erosion, reducing the expansion and intensification of desertification and protecting land resources and the ecological environment. These devices are often combined with afforestation to provide a stable environment for plant growth, prevent soil erosion and desert expansion, and promote vegetation restoration and ecological balance.
[0003] A search revealed that this utility model, authorized by Chinese Patent Publication No. CN 221941298 U, belongs to the technical field of windbreak and sand-fixing devices, specifically relating to a windbreak and sand-fixing device for desert control. It includes a base, a supporting base fixedly connected to the lower end of the base, a baffle fixedly connected to the upper end of the base, a connecting plate slidably connected inside the base, and a positioning rod fixedly connected to the surface of the connecting plate. The positioning rod is slidably connected to the base, and a threaded rod is connected inside the base via a bearing. This utility model, by incorporating the connecting plate, positioning rod, and threaded rod, allows rotation of the threaded rod to cause threaded movement between the threaded rod and the connecting plate, thereby enabling the connecting plate to drive the positioning rod into the desert. This, combined with the supporting base, reinforces the base, solving the problem of unstable installation and tendency for tilting or leaning during use of windbreak and sand-fixing devices for desert control.
[0004] The sand-fixing devices in the aforementioned patents still have certain shortcomings. The method of sand fixation using baffles in the aforementioned patents is difficult to apply to large-scale quicksand control areas, and its cost is relatively high. In the traditional methods of straw checkerboard and nylon netting, the straw checkerboard has a short service life and poor stability, while the nylon netting has limited strength and is easily torn by strong winds or buried by sand, which limits its use. Utility Model Content

[0012] Preferred technical solution four: Several protrusions are evenly arranged on the outer side of the bottom end of the grounding plug.
[0013] This solution allows the bottom of the grounding pole to have a wider contact with the desert, increasing its insertion friction.

[0023] Please see Figure 1-4 ,
[0024] Example 1: A PVC mesh device for desert control includes several first sand-proof nets 1 and second sand-proof nets 3. The first sand-proof nets 1 and second sand-proof nets 3 are arranged perpendicularly to each other. Several spinning net grounding components 2 are provided on both the first sand-proof nets 1 and second sand-proof nets 3. Several connecting slots 4 are evenly provided on the second sand-proof nets 3. Fixing holes 5 are provided on the top side wall of the connecting slots 4. Several connecting screws 6 are evenly provided on the top of the first sand-proof nets 1. The top of each connecting screw 6 passes through the fixing hole 5 and is fitted with a connecting nut 7.
[0025] The spinning net grounding assembly 2 includes a side connecting rod 201 disposed on the side of the first sand-proof net 1 and the second sand-proof net 3. A central through hole 202 is opened in the middle of the side connecting rod 201. Two fastening screws 203 are symmetrically arranged at the top of the side of the side connecting rod 201. A plurality of connecting holes 204 are evenly opened on the first sand-proof net 1 and the second sand-proof net 3. The fastening screws 203 all pass through the connecting holes 204. A fastening nut 205 is sleeved on the end of the fastening screw 203. A grounding plug 206 is inserted into the central through hole 202.
[0026] Several ventilation holes are provided on both the first sand-proof net 1 and the second sand-proof net 3.
[0027] Example 2: The difference between this example and Example 1 is that the width of the connecting slot 4 is the same as the thickness of the first sandproof mesh 1.
[0028] This allows the first sand-proof net 1 to be inserted into the connecting slot 4.
[0029] Example 3: The difference between this example and Example 1 is that several protrusions are evenly arranged on the outer side of the bottom end of the grounding plug 206.
[0030] This allows the bottom of the grounding rod 206 to have a wider contact with the desert when inserted into the desert, thus increasing its insertion friction.
[0031] Example 4: The difference between this example and Example 1 is that a baffle is provided at the top of the grounding plug 206.
[0032] This makes the top of the grounding plug 206 more stable when inserted into the middle through hole 202.
[0033] In this embodiment, the existing method of using baffles to fix sand is difficult to apply to large-scale quicksand control areas, and its cost is relatively high. In the traditional methods of straw checkerboard and nylon netting, the straw checkerboard has a short service life and poor stability, while the nylon netting has limited strength and is easily torn by strong winds or buried by sand, which has great limitations in its use.
[0034] In summary, in practical implementation, when users need to control shifting sand in the desert, they transport multiple rolled-up first sand-proof nets 1 and second sand-proof nets 3 to a designated location by vehicle. Both the first sand-proof nets 1 and second sand-proof nets 3 are made of high-quality PVC material and have strong resistance to ultraviolet rays, high and low temperatures, salt and alkali, and wind erosion. Users insert several first sand-proof nets 1 into the connecting slots 4 opened on the second sand-proof nets 3, and the connecting screws 6 are perpendicularly connected to the first sand-proof nets 1 and second sand-proof nets 3 by passing through the fixing holes 5. By fitting connecting nuts 7 on the top of the connecting screws 6 through the fixing holes 5, the first sand-proof nets 1 and second sand-proof nets 3 are arranged crosswise, thereby forming several sand-proof grids in the desert to better block the shifting sand in the desert and achieve a certain sand control effect.
[0035] The sides of the first sand-proof net 1 and the second sand-proof net 3 are also equipped with several spinning net grounding components 2. The fastening screws 203 in the spinning net grounding components 2 all pass through the connecting holes 204. By fitting fastening nuts 205 on the ends of the fastening screws 203, the side connecting rods 201 can be fixed to the sides of the first sand-proof net 1 and the second sand-proof net 3. At this time, the user can insert the grounding plug 206 into the central through hole 202 opened in the middle of the side connecting rod 201, so that the bottom end of the grounding plug 206 is deeply inserted into the desert, thereby providing stable support for the cross-set first sand-proof net 1 and second sand-proof net 3, effectively improving their wind resistance and making them more convenient to use.
