Description

Technical Field

[0001] This utility model relates to the field of windbreak and sand-fixing mesh frame technology, specifically a windbreak and sand-fixing mesh frame for desert ecological restoration that is easy to assemble and disassemble. Background Technology

[0002] Windbreak and sand-fixing netting is a key ecological engineering facility for addressing the threat of desertification in arid and semi-arid regions. Its function stems from precise intervention in the laws of wind and sand movement. The three-dimensional mesh structure, constructed from high-polymer materials, utilizes a honeycomb weaving technique with a "loose upper layer and dense lower layer" or a grid design with alternating sparse and dense sections to create a wind speed gradient based on aerodynamic principles. When strong winds pass through the netting, the permeable pores in the upper layer reduce airflow resistance, while the dense mesh in the lower layer reduces wind speed through frictional energy dissipation, transforming strong winds on the outside into weak winds on the inside. Ultimately, a vortex zone is formed behind the netting, prompting sand particles in the wind-blown sand to settle prematurely. This process not only directly intercepts suspended sand particles in the air, reducing the amount of dust blown away, but also creates a stable microclimate environment for the germination of seeds and the growth of seedlings of desert plants by reducing the intensity of surface wind erosion.

[0003] Traditional windbreak and sand-fixing supports mostly use the method of directly inserting them into the sand. However, due to the loose and highly mobile nature of sand, the supports are difficult to maintain vertical stability for a long time. They are prone to collapse and failure when encountering strong winds or sand dune movement, leading to frequent reconstruction of the protection system. In addition, the existing construction process requires the support insertion and sand net laying to be completed in steps. After the supports are firmly inserted into the sand, the net body needs to be manually attached to the top of the supports and then fixed a second time with plastic caps.

[0004] The cap and support are mostly designed separately, which not only requires carrying a lot of extra accessories, increasing the construction burden, but also makes the cap prone to falling off due to material aging or external impact under wind and sand erosion, resulting in loose netting and reduced protective effect. The above defects seriously restrict the applicability and durability of traditional supports in complex sandy environments. Utility Model Content

[0005] The purpose of this invention is to provide a transfer platform for compressor maintenance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a windbreak and sand-fixing net frame for desert ecological restoration that is easy to assemble and disassemble, comprising a net frame body, an insertion mechanism provided in the inner cavity of the net frame body, a sliding groove provided on the surface of the net frame body, a plurality of limiting grooves provided on the surface of the net frame body, a placement groove provided on the surface of the net frame body, a limiting mechanism provided in the inner cavity of the net frame body, and a locking block fixed in the inner cavity of the net frame body.

[0007] Preferably, the insertion mechanism includes a foot pedal that slides on the inner wall of the mesh frame body. The surface of the foot pedal is provided with a sleeve. The sleeve includes an upper sleeve rod and a lower sleeve. A first spring is fixed to the upper sleeve rod of the sleeve. The other end of the first spring is fixed to the lower sleeve. A rotating shaft is fixed to the inner cavity of the foot pedal. An insertion stick is rotatably mounted on the surface of the rotating shaft.

[0011] Preferably, the cuttings are distributed in a ring array around the center of the frame body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The purpose of this utility model is to provide a windbreak and sand-fixing net frame for desert ecological restoration that is easy to assemble and disassemble. By adding a cutting insertion mechanism to form a fixed system, the cutting insertion mechanism uses its conical drill bit structure to penetrate into the sand layer to form initial anchor points. Auxiliary strips are placed in different directions on the net frame body and are radially inserted between the bottom of the net frame body and the sand layer. The multi-point cross-fixing significantly improves the anti-overturning ability. Even if it encounters strong winds or sand dune displacement, it can still maintain structural stability. At the same time, the limiting mechanism adopts an elastic buckle design, and the edge of the sand-fixing net can be directly inserted into the limiting groove and adaptively adjusted along the track without the need for additional disassembly tools or accessories. This not only avoids the defect of traditional caps being easy to fall off, but also achieves the dual requirements of rapid deployment and long-term protection. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5As shown, a windbreak and sand-fixing mesh frame for desert ecological restoration that is easy to assemble and disassemble includes a mesh frame body 1, which consists of an upper part and a lower part for initially breaking the sand surface and inserting into the ground. The inner cavity of the mesh frame body 1 is provided with a cutting insertion mechanism 2, which includes a foot pedal 21 that slides against the inner wall of the mesh frame body 1. A sleeve 22 is provided on the surface of the foot pedal 21. The sleeve 22 includes an upper sleeve rod and a lower sleeve. A first spring 23 is fixed to the upper sleeve rod of the sleeve 22. The materials of the first spring 23 and the second spring 62 are... All materials are made of stainless steel, which can maintain performance even in extremely dry and subsequently moist conditions. The other end of the first spring 23 is fixed to the sliding sleeve. The sleeve 22 can be used to limit and protect the first spring 23. The inner cavity of the foot pedal 21 is fixed with a rotating shaft 24. The surface of the rotating shaft 24 has several cutting sticks 25 rotating on it. The number of cutting sticks 25 is several, and they are all arranged in a circular array around the center of the grid body 1, which can cope with external forces from different directions. The cutting sticks 25 are conical in shape, and are used for cutting. At this time, the main body 1 of the grid frame is initially inserted into the sand. Then, the worker steps on the foot pedal 21, which reduces the effort required for the worker during insertion. Under the action of external force, the sleeve 22 is compressed, and the first spring 23 is squeezed. As the foot pedal 21 descends, the insertion sticks 25 connected to it also descend. When the insertion sticks 25 contact the limiting grooves 4, the insertion sticks 25 rotating on the surface of the rotating shaft 24 change direction, causing them to move diagonally downwards, so that each insertion stick 25 is guided by the corresponding limiting groove 4. The cutting mechanism 2 is inserted into the sand in different directions to provide support in various directions, thereby stabilizing the main body 1 in the sand and fixing it in the sand. The surface of the main body 1 is provided with sliding grooves 3 to assist the cutting mechanism 2 in sliding within the inner cavity of the main body 1. The surface of the main body 1 is provided with several limiting grooves 4 to assist the cutting mechanism 2 in inserting more accurately into the sand and preventing deviation. The surface of the main body 1 is provided with placement grooves 5 for placing the sand-proof net.

[0022] The inner cavity of the grid frame body 1 is provided with a limiting mechanism 6. The limiting mechanism 6 includes a fixed shaft 61 that rotates on the inner wall of the grid frame body 1. A second spring 62 is fixed to the surface of the fixed shaft 61. One end of the second spring 62 is fixed to the inner wall of the grid frame body 1. A limiting rod 63 is fixed to the surface of the fixed shaft 61 support mechanism. A fiber rope 64 is fixed to the surface of the limiting rod 63. The other end of the fiber rope 64 passes through the outer side of the grid frame body 1 and slides through the inner wall of the penetration point. A pull ring 65 is fixed to the other end of the fiber rope 64. When the sand-proof net is inserted into the placement groove 5, the limiting rod 63 rotates downward under the action of the second spring 62, allowing the sand-proof net to smoothly enter the placement groove 5. After placement, the elasticity of the second spring 62 can restrict the limiting rod 63. Because the limiting rod 63 is inclined and its length is greater than the width of the placement groove 5, it can better block the sand-proof net inside the placement groove 5. When it needs to be removed from the placement groove 5... When placing the sand-proof net, simply pull the pull ring 65. The pull ring 65 will drive the limiting rod 63 at the other end of the fiber rope 64 to rotate, thereby opening the restriction and taking the sand-proof net out of the placement slot 5. This not only eliminates the need for disassembly and assembly, but also makes placing and removing the sand-proof net more convenient and reliable. It is used to limit the sand-proof net after placement to prevent it from falling out. The inner cavity of the net frame body 1 is fixed with a locking block 7 to limit the rotation of the upper part of the net frame body 1. The surface of the locking block 7 has a locking groove 8, the same width as the foot pedal 21. After the foot pedal 21 descends to a suitable height, the upper part of the net frame body 1 is rotated so that the locking groove 8 on the locking block 7 fits into the foot pedal 21. This not only limits the foot pedal 21 to a fixed height, but also prevents the net frame body 1 from rotating under the action of external force, causing the foot pedal 21 to rebound under the action of the first spring 23. As the foot pedal 21 rebounds, the insertion stick 25 also retracts accordingly, and then loses its auxiliary support for the net frame body 1.

[0023] Working principle: When a sand-control net frame needs to be installed, the worker simply inserts the net frame body 1 into the sand, then steps on the foot pedal 21. As the foot pedal 21 descends, it compresses the first spring 23, causing the cutting stub 25 to descend as well. The descending cutting stub 25, pulled by the corresponding limiting groove 4, is inserted diagonally downwards into the sand. After insertion, the upper part of the net frame body 1 is rotated so that the groove 8 on the surface of the locking block 7 rotates to the position corresponding to the foot pedal 21, thus blocking the foot pedal 21. Releasing the foot pedal 21 completes the insertion. The four cutting stubs 25 in different directions can resist upward pressure from various directions. The external force helps stabilize the main body 1 of the auxiliary net frame. As the slot 8 locks the foot pedal 21, it also restricts the rotation of the main body 1 of the net frame to prevent the foot pedal 21 from moving again due to the external force. After the fixing is completed, the sandproof net is put into the opening of the placement slot 5. Its limiting rod 63 rotates downward under the action of the second spring 62, so that the sandproof net can smoothly enter the placement slot 5. After the placement is completed, the elasticity of the second spring 62 can close itself to complete the restriction. When it is necessary to remove the sandproof net from the placement slot 5, simply pull the pull ring 65 to drive the limiting rod 63 to rotate through the fiber rope 64, thereby opening the restriction and taking out the sandproof net.
