Description

Technical Field

[0001] The utility model relates to the technical field of sand prevention nets, in particular to a suspended ball-type sand prevention and blocking fine-mesh net made of metal material. Background Art

[0002] Windbreaks and sand fixation are crucial for ecological and environmental protection, particularly in arid, semi-arid, and severely desertified areas. To effectively curb wind and sand intrusion, protect soil resources, and promote vegetation restoration, a series of scientific and systematic measures are commonly implemented. Plastic grid sand barriers and fine-mesh sand control nets are two common and effective technical approaches. Plastic grid sand barriers, made of plastic in a grid pattern of specific specifications, are buried in the sand, altering the surface morphology and increasing surface roughness. This significantly reduces wind speed and reduces the wind's ability to transport sand particles, facilitating moisture retention and vegetation growth in the sand, effectively curbing desertification. Fine-mesh sand control nets are a mesh structure woven from high-strength, corrosion-resistant materials with a fine mesh that effectively blocks the flow of windblown sand. These fine-mesh nets are laid on surfaces susceptible to wind and sand intrusion to slow wind speeds and reduce wind erosion, thereby achieving sand fixation. They also provide shelter for subsequent vegetation restoration, promoting seed germination and seedling growth, and gradually establishing a stable ecological barrier.

[0003] Windbreaks and sand fixation typically involve deploying fine-mesh nets or plastic sand barriers. While these measures have achieved some success, they still have many drawbacks. For example, plastic sand barriers, primarily made of high-density polyethylene (HDPE), have poor weather resistance and sand control effectiveness in desertification environments, and are prone to damage at joints. Plastic, being a non-degradable material, is highly susceptible to ecological damage, and damage to sand control structures is expensive to replace and reinstall. Existing sand control nets are typically connected by welding, which is inconvenient. Therefore, a sand control net that is easy to install is needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing sand prevention technology that the installation steps of the sand prevention device are cumbersome and inconvenient, and to propose a sand prevention and sand blocking fine mesh net with a convenient and flexible installation and use method.

[0005] The utility model can be realized by the following technical solutions:

[0006] A fine-mesh sand-blocking net comprises: a base in the shape of an inverted cone, two of which are provided, the tops of the two bases being fixedly connected to column sleeves respectively, and the cylinder walls of the column sleeves being provided with straight seams; a sand-blocking net comprising an integrally formed lower flat net and an upper arc net; fixed struts are provided on the left and right sides of the sand-blocking net, and the sand-blocking net is fixedly connected to the column sleeves via the fixed struts; a wind-proof ball is connected to the upper edge of the upper arc net via a chain and hangs down naturally; during installation, the base is buried underground, and the concave side of the upper arc net of the sand-blocking net is the windward side.

[0007] Hanging metal balls can be used to block blowing sand. When the wind and sand flow drives sand over the upper part and top of the sand-control net, the metal hanging balls float with the wind and sand flow, destroying the air flow vortex, and can prevent some sand from being carried to the leeward side of the sand-control net by the wind and sand flow.

[0008] Preferably, the column sleeve has one or more straight seams formed in its wall, so that two adjacent sand-control nets share the same column sleeve. Adjusting the relative positions of the straight seams allows the installation angle of adjacent sand-control nets to be varied. By adjusting the relative positions and number of the straight seams, multiple sand-control nets can be connected through a single column sleeve, and the installation angle of adjacent sand-control nets can be varied.

[0009] In some embodiments of the present invention, two straight slits are formed on the wall of the column sleeve, and the two straight slits are symmetrical.

[0010] Preferably, the sand-proof and sand-blocking dense mesh net further includes a reinforcement component, and each of the column sleeves is provided with at least two groups of the reinforcement components, and at least two groups of reinforcement components are respectively arranged on both sides of the sand-proof net.

[0011] In some embodiments of the present invention, the reinforcement assembly includes a lifting ring fixed to the wall of the column sleeve, a diagonal steel wire and a ground anchor. One end of the diagonal steel wire is fixedly connected to the lifting ring, and the other end is fixedly connected to the ground anchor. The ground anchor is buried underground during installation.

[0012] Preferably, the base is prefabricated from cement concrete, a blind hole is provided in the center of the top plane, and the column sleeve is installed on the base through the blind hole.

[0013] In some embodiments of the present invention, during installation, the buried depth of the base is more than 50 cm, and the distance between the two column sleeves is 2.5 m to 3.0 m.

[0014] Preferably, the lower edge of the lower flat net of the sand-proof net is buried underground with a depth of 10 cm to 20 cm.

[0015] Preferably, the sand-proof net is a metal net, the height of the lower flat net is 1.2m~1.4m, and the arc length of the upper arc net is 0.4m~0.6m; the porosity of the sand-proof net is 50%, and the pore size is 1mm×1mm.

[0016] Further preferably, the column sleeve is made of stainless steel and the windproof ball is made of metal.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The sand-proof and sand-blocking dense-mesh net proposed in the utility model has a main structure of metal material, which significantly increases the weather resistance of the sand-blocking wall; based on the prefabricated and assembled technical idea, the sand-proof net is assembled on the steel column sleeve, and adjacent sand-proof nets can share a column sleeve during installation, replacing the traditional welding and binding method, which is convenient to install, disassemble and replace, and has good stability at the connection; the utility model also proposes a sand-proof and sand-blocking dense-mesh net with a circular arc shape on the top and an upright shape on the bottom, and metal balls are hung on the edge of the arc net, which can destroy the airflow vortex and prevent some sand particles from being carried to the leeward side of the sand-proof net by the wind and sand flow, and has a good sand-proof effect.

The sand-proof net 3 has a lower flat net 31 and an upper arc net 32, and a hollow metal wind-proof ball 4 connected by a metal chain is hung on the top of the upper arc net 32.

[0032] In the installation state, first bury the base 1 in the soil, leaving only the cylindrical hole on the base 1 exposed, then insert the hollow column sleeve 2 with symmetrical gaps into the cylindrical hole on the foundation 1, then insert the fixed struts 33 at both ends of the sand-proof net 3 from the upper end of the column sleeve 2 into the corresponding straight seams 21, and then hang the hollow metal wind-proof ball 4 with a metal chain evenly on the top of the upper arc net 32 ​​of the sand-proof net 3. This can achieve rapid installation of the entire sand-proof structure and achieve a good sand-proof effect.

[0033] Example 2

[0035] During installation, the column sleeve 2 is first mounted on the base 1, which is then buried 50 cm deep in the soil. The column sleeve 2 is hollow and has two symmetrical straight seams 21. The fixed struts 33 at each end of the sand-control net 3 are then inserted from the upper end of the column sleeve 2. The fixed struts 33 engage the column sleeve's straight seams 21, tightening the sand-control net 3. The sand-blocking fine-mesh net proposed in this utility model can be connected to multiple pieces of sand-control net 3. A second piece of sand-control net can be snapped into another straight seam 21 of the column sleeve 2 in the same manner.

The column sleeve 2 is hollow and has three symmetrical straight seams 21. Next, the fixed struts 33 at both ends of the sand-proof net 3 are inserted into the column sleeve 2 from the upper end. The fixed struts 33 engage the column sleeve straight seams 21 to tighten the sand-proof net 3. The sand-blocking fine-mesh net proposed in this utility model can be connected in multiple pieces. The second and third pieces of sand-proof net 3 can be inserted into the other two straight seams 21 of the column sleeve 2 in the same manner. The angle between two adjacent pieces of sand-proof net 3 is adjustable.

[0041] To further strengthen the fine-mesh sand-blocking net, a reinforcement component is installed. Specifically, three symmetrical rings are set on the column sleeve 2 for connecting ground anchors and pull wires. These three reinforcement components are located in three different areas of the three sand-blocking nets connected by the same column sleeve 2. The ground anchors are buried at a depth of 10cm to 20cm.
