Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to an insect-proof structure for basement ventilation openings. Background Technology

[0002] Insect prevention through ventilation openings refers to the use of a series of technical means and facilities to prevent insects and other organisms from entering a specific space through ventilation openings, thereby ensuring the hygiene, safety and normal function of the environment within that space. This measure is widely used in various buildings, industrial sites and some facilities with high environmental requirements.

[0003] In the construction of basement ventilation systems, the insect-proof structure of the ventilation openings is prone to clogging with dust and debris over time, and insects may gather around the mesh, reducing the insect-proof effect. Furthermore, while the use of a finer insect-proof net can block more insects, it also greatly increases ventilation resistance, leading to poor ventilation. Therefore, it is necessary to provide a construction insect-proof structure for basement ventilation openings. The insect-proof net can effectively prevent insects from entering the ventilation shaft, ensuring that the basement environment is free from insect infestation. At the same time, the rotating frame can be driven to rotate and open when needed to increase the exhaust volume and meet different ventilation requirements. Utility Model Content

[0013] In the following description, embodiments of the insect-proof structure for basement ventilation openings of this utility model will be presented with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates an embodiment of an insect-proof structure for a basement ventilation opening, comprising a ventilation shaft 1. Pre-embedded frames 2 are embedded on both sides of the ventilation shaft 1. A rotating frame 3 is installed within the inner cavity of the pre-embedded frame 2. Rotating components 7 are fixedly connected to the top of the front and rear sides of the rotating frame 3, and are rotatably connected to the pre-embedded frame 2. A sealing gasket 8 is fixedly connected to one side of the inner wall of the pre-embedded frame 2. The edge of the rotating frame 3 near the ventilation shaft 1 is pressed against the surface of the sealing gasket 8. A protective component 4 is provided on the side of the rotating frame 3 near the ventilation shaft 1. The protective component 4 includes multiple louvers 41 fixedly installed within the inner cavity of the rotating frame 3. A positioning frame 42 is fixedly connected to the edge of the rotating frame 3 near the ventilation shaft 1. An insect-proof net 43 is inserted into the inner cavity of the positioning frame 42. Two threaded knobs 44 are threaded through the bottom of the insect-proof net 43 near the ventilation shaft 1. The threaded knobs 44 penetrate the insect-proof net 43 and are threadedly connected to the rotating frame 3. The threaded knobs 44 provide protection for the insect-proof net 43. The limiting and fixing function allows the insect net 43 to be stably attached to the side of the rotating frame 3 near the ventilation shaft 1. It is also easy for users to disassemble and clean its surface. An electric telescopic rod 45 is fixedly installed at the top of the inner cavity of the ventilation shaft 1. The output end of the electric telescopic rod 45 is fixedly connected to the lifting plate 46. Guide rods 5 are fixedly connected to both sides of the top of the inner cavity of the ventilation shaft 1. Guide tubes 6 are fixedly connected to both sides of the top of the lifting plate 46. The guide tubes 6 are slidably connected to the surface of the guide rods 5. Through the cooperation of the guide rods 5 and the guide tubes 6, the lifting plate 46 is limited and guided, so that the lifting plate 46 can maintain vertical up and down movement, ensuring the stability of the lifting plate 46 and the connecting plate 47 during the displacement process. The bottom sides of the lifting plate 46 are rotatably connected to the connecting plate 47. The opposite sides of the two pre-embedded frames 2 are fixedly connected to the connectors 48. The end of the connecting plate 47 away from the lifting plate 46 is rotatably connected to the connector 48.

[0015] Working Principle: When using this invention, the user draws indoor air into the ventilation shaft 1 through the indoor forced ventilation duct. The air entering the ventilation shaft 1 passes through the inner cavity of the pre-embedded frame 2 and between multiple louvers 41 before being discharged outdoors. When ventilation is not in progress, the louvers 41 shield against rain and snow, preventing them from entering the ventilation shaft 1. Simultaneously, the insect net 43 effectively prevents outdoor insects from entering the ventilation shaft 1. When cleaning or maintenance of the insect net 43 is required, or when forced ventilation is needed, the electric telescopic rod 45 opens and pushes the lifting plate 46 downwards. This causes the lifting plate 46 to slide the guide tube 6 downwards on the surface of the guide rod 5. During the sliding process of the lifting plate 46, the connecting plate... 47 causes compression, causing the connecting plate 47 to rotate downwards and push forward. Then, with the cooperation of the connector 48, the two rotating frames 3 rotate around the rotating part 7 as the rotation center. Finally, the rotating frame 3 is disengaged from the inner cavity of the pre-embedded frame 2. During forced ventilation, the air can be discharged from the opening position of the pre-embedded frame 2 and the rotating frame 3, enhancing the ventilation effect. The air generated during ventilation can effectively prevent mosquitoes from entering. While the rotating frame 3 is disengaging from the inner cavity of the pre-embedded frame 2, the user can rotate the threaded knob 44 to disengage the threaded knob 44 from the rotating frame 3. Then, pull the insect net 43 to one side to disengage the insect net 43 from the inner cavity of the positioning frame 42. Remove the insect net 43 and clean the mosquitoes or impurities on its surface.

[0016] In summary, the insect-proof structure for the basement ventilation opening, through the combined use of the rotating frame 3 and the protective component 4, effectively prevents mosquitoes from entering the inner cavity of the ventilation shaft 1. Simultaneously, the protective component 4, in conjunction with the pre-embedded frame 2, drives the rotating frame 3 to rotate, increasing the exhaust volume during ventilation. Furthermore, the user can easily clean and maintain the insect-proof netting, thus effectively preventing mosquitoes and foreign objects from entering and enhancing the exhaust volume.
