Technical Field

[0001] This utility model belongs to the field of sand prevention and control technology, and in particular relates to a sand-blocking fence with vertically arranged holes. Background Technology

[0002] To combat wind and sand erosion, various windbreak and sand-fixing measures have been adopted, among which sand-blocking fences are a common and effective method. However, existing sand-blocking fences have certain limitations in structural design and functional implementation. For example, some fences are not ideal in terms of wind and sand blocking, making it difficult to effectively reduce wind speed and the amount of sand and dust passing through; some fences are not installed and fixed securely enough, making them prone to damage or displacement under severe weather conditions such as strong winds; and some fences are made of inappropriate materials, resulting in poor durability, a short service life, and increased maintenance and replacement costs.

[0003] Therefore, developing a sand-blocking fence that has better sand-blocking effect, is more stable to install, and has greater durability is of great practical significance. Utility Model Content

[0027] The present invention will now be described in further detail with reference to the accompanying drawings:

[0028] This utility model provides a sand-blocking fence with vertically arranged holes, such as... Figure 1As shown, it includes a baffle 1, multiple fixing posts 3 and multiple fixing plates 4; the multiple fixing posts 3 are connected to one side of the baffle 1, and the multiple fixing posts 3 are spaced apart along the length direction of the baffle 1; the multiple fixing plates 4 are connected to the other side of the baffle 1, and the fixing posts 3 and fixing plates 4 are connected in a one-to-one correspondence; the baffle 1 has multiple vertical holes 2 evenly distributed in an array, and the longitudinal length of the vertical holes 2 is greater than its transverse length.

[0029] This utility model's baffle 1 employs an array of evenly distributed vertical holes 2. Compared to the traditional horizontal opening design, the vertical hole arrangement significantly reduces the accumulation of sand at the hole edges, preventing localized stress concentration and material corrosion caused by sand accumulation. Due to the longitudinal arrangement of the vertical holes 2, sand is more easily guided upwards through the holes, reducing sand retention at the bottom of the baffle 1, thus effectively reducing the risk of bottom corrosion and extending the service life of the sand-blocking fence. Secondly, in terms of wind and sand blocking performance, the arrangement of the vertical holes 2 optimizes the airflow distribution, allowing sand to form a more stable vortex structure when passing through the baffle 1. Compared to the horizontal hole design, the vertical holes 2 maintain a more consistent sand-blocking efficiency under different wind speeds, preventing a sudden drop in sand-blocking effect due to excessively high wind speeds and maintaining breathability even with excessively low wind speeds. Furthermore, this utility model uses fixed columns 3 and fixed plates 4 for one-to-one fixed connection, jointly securing the baffle 1 and enhancing the rigidity and stability of the overall structure. The fixed columns 3 are spaced apart along the length of the baffle 1, which ensures convenient installation and effectively disperses wind loads, preventing overturning or deformation under strong wind conditions. This is especially suitable for long-term sand control projects in harsh environments such as deserts and Gobi. The clamping connection between the baffle 1 and the fixed columns 3 and fixed plates 4 not only simplifies the on-site construction process but also facilitates later maintenance and partial replacement, reducing the total life cycle cost.

[0030] The baffle 1 is made of high-density polyethylene (HDPE). HDPE has excellent weather resistance and UV resistance, and can maintain structural stability for a long time in the extreme temperature difference and strong UV radiation environment of the desert, avoiding the problems of easy corrosion of traditional metal materials or easy aging of wood materials. Secondly, HDPE material has strong flexibility, and can buffer stress through moderate deformation under strong wind loads, reducing the risk of structural fracture. At the same time, its smooth surface can reduce sand particle adhesion, and together with the vertical holes 2, it can further reduce wind resistance. In addition, as an environmentally friendly material, HDPE is not only lightweight (easy to transport and install), but also has chemical corrosion resistance, which can resist the erosion of salt, alkali and sand in the desert environment, with a long service life and significantly reduced maintenance costs.

[0031] The fixing posts 3 and fixing plates 4 are made of galvanized steel or fiberglass. Galvanized steel undergoes hot-dip galvanizing, giving it excellent rust resistance and making it resistant to corrosion from saline-alkali and humid conditions in the desert environment. Its high strength and rigidity ensure the structural stability of the sand-blocking fence under strong winds. Fiberglass, on the other hand, is lightweight, high-strength, and corrosion-resistant. It weighs only one-quarter of steel but possesses considerable tensile strength and is completely unaffected by electrochemical corrosion, making it particularly suitable for high-salt-alkali desert areas. Both materials have good environmental adaptability. Galvanized steel offers excellent cost-effectiveness, while fiberglass is maintenance-free. In practical applications, the choice can be made flexibly based on specific project requirements and budget.

[0032] The baffle 1 has through holes; the fixing post 3 and the fixing plate 4 are fixedly connected by screws 5 passing through the through holes, realizing the rapid assembly and reliable fixation of the sand-blocking fence. The presence of through holes eliminates the need for pre-drilling during installation, and with the use of standard screws, rapid on-site assembly can be achieved, greatly improving construction efficiency. Furthermore, the screw fastening method facilitates disassembly and replacement during later maintenance, while ensuring that the connection nodes will not loosen or fall off under wind vibration conditions.

[0033] The lower end of the fixed post 3 is provided with a square pyramidal structure that tapers towards the bottom. When the fixed post 3 needs to be inserted into the sand, the tapering square pyramidal structure can easily break through the sand surface like an awl, reducing insertion resistance and allowing the fixed post 3 to penetrate into the sand more smoothly and effortlessly, greatly improving installation efficiency.

[0034] The edge of the baffle 1 is provided with reinforcing ribs, which can effectively enhance the structural strength of the edge of the baffle 1, making it less prone to deformation, bending or even breakage when subjected to external impact, pressure or long-term stress, thus greatly improving the overall stability and durability of the baffle.

[0035] The inner wall of the vertical hole 2 is provided with a flow guide groove, which is spiral in shape. The flow guide groove guides the airflow to form a rotating and upward flow field, which maintains a stable sand-blocking effect and effectively reduces the impact of wind pressure on the fence structure. The special spiral pattern of the flow guide groove can change the movement trajectory of sand particles, causing fine sand to separate from the airflow under centrifugal force, greatly reducing the penetration of fine sand.

[0036] The installation method of this utility model is as follows: first, nail the fixing post 3 into the sand according to the length of the baffle 1, then attach the baffle 1 tightly to the fixing post 3, attach the fixing plate 4, and fix it into one piece with screws 5.

[0037] This invention significantly optimizes the airflow distribution through an array of uniformly distributed vertical holes 2, creating a stable vortex structure for sand and dust, maintaining high sand-blocking efficiency while reducing wind pressure impact. The high-density polyethylene baffle 1, combined with a galvanized steel / fiberglass fixing structure, offers weather resistance, corrosion resistance, and structural stability. The four-sided pyramidal structure at the bottom of the fixing column 3 enhances installation convenience and wind resistance. The spiral guide grooves on the inner wall of the vertical holes 2 further enhance airflow guidance and sand separation. This invention features a simple structure, convenient installation and use, easy-to-use sand-blocking fence materials and manufacturing, strong corrosion resistance, increased service life, and wide applicability, making it suitable for large-scale application in desert areas.

[0038] Example

[0039] The sand-blocking fence consists of HDPE board, fixing posts 3, fixing plates 4, and screws 5. The HDPE board has evenly distributed vertical holes 2 in an array. First, the fixing posts 3 are driven into the sand in a straight line at 2m intervals, with the fixing posts 3 1m above the sand surface. Then, the HDPE board is tightly attached to the fixing posts 3, and the fixing plates 4 are attached to the other side of the HDPE board. Finally, the screws 5 are used to fix the fixing posts 3, HDPE board, and fixing plates 4 into one unit.

[0040] The HDPE board has a height of 1m, a thickness of 2mm, and a length of 2m; the vertical hole 2 is 8cm long and 2.5cm wide, with adjacent vertical holes 2 2cm apart horizontally and 2.5cm apart vertically; the fixing column 3 is 1.2m high, with a column cross-section of 5cm long and 5cm wide; the lower end of the fixing column 3 is a four-sided pyramid shape for easy insertion into the ground; the fixing plate 4 is 1m high and 4cm wide.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
