Description

Technical Field

[0001] The utility model relates to the technical field of anti-sand at construction sites, in particular to an anti-sand device at construction sites used for engineering technology. Background Art

[0002] As an important part of urban engineering technology construction, construction sites are often faced with various complex environmental factors during their construction process, especially in areas with strong winds and sand. Wind and sand will not only affect the construction progress and quality, but also pose a safety threat to construction personnel and equipment. Therefore, it is necessary to install sand-proof devices. Although existing sand-proof devices have certain protective properties, they are mostly fixed by bolt installation. When they need to be disassembled and replaced, they have the defect of being inconvenient to disassemble and assemble, which easily causes dust, and thus cannot meet the needs of users.

[0003] A Chinese patent discloses a construction site sand prevention device for engineering technology (authorization announcement number CN218293123U). The patent technology sets a reaction force of a spring so that the spring drives the moving block to move toward each other, and the moving block drives the limit rod to move toward each other, so that the limit rod and the limit groove are plugged in, and the plug plate is fixed to prevent the frame from being loose. When wind and sand are generated, the sand prevention net can block the wind and sand, reduce the generation of wind and sand, and improve the sand prevention effect. By setting the above structure, it has the advantage of convenient disassembly and assembly, solves the problem that the existing protective device is inconvenient to disassemble and assemble, and can meet the use needs of users;

[0004] However, it has certain drawbacks: during long-term use, sand is easily mixed and accumulated on the mesh surface of the sand-proof net. As the sand continues to accumulate on the sand-proof net, its weight will gradually increase. When the weight of the sand exceeds the load-bearing range of the sand-proof net, the sand-proof net will break or break due to unsustainable load. In addition, the mesh holes of the sand-proof net are blocked by sand, making it impossible for the airflow to pass through the sand-proof net, resulting in the possibility of deformation of the sand-proof net. Utility Model Content

[0005] The utility model aims to provide a construction site sand prevention device for engineering technology to solve the problems raised in the above background technology.
