[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0026] Embodiment 1, as Figure 1-Figure 6As shown, the utility model provides a construction ventilation device, including: a base 6, an electric telescopic rod 3 is fixedly connected to the top center position of the base 6, a ventilation box 8 is fixedly connected to the top of the electric telescopic rod 3, and the outer surfaces of both sides of the ventilation box 8 are fixedly connected with mounting components 4; the mounting component 4 includes a pipe 401, a slide groove 406 is opened on the top of the pipe 401, a mounting groove 410 is opened on the inner wall of one side of the slide groove 406, a movable rod 409 is fixedly connected to the inner wall of one side of the mounting groove 410, a clamping block 411 is fixedly connected to one end of the movable rod 409, a mounting frame 403 is slidably connected to the inner surface of the mounting groove 410, and the outer surface of one side of the mounting frame 403 A card slot 405 is provided, a dustproof net 413 is provided on the inner surface of the mounting frame 403, a spring 408 is sleeved on the outer surface of the movable rod 409, the outer surface of the card block 411 is engaged with the outer surface of the card slot 405, a limiting slot 412 is provided on the inner top of the mounting slot 410, a push block 404 is slidably connected to the inner surface of the limiting slot 412, the bottom of the push block 404 is fixedly connected to the top of the card block 411, a handle 402 is fixedly connected to the top of the mounting frame 403, the outer surface of the card block 411 is slidably arranged with the inner surface of the mounting slot 410, the outer surface of the pipe 401 is fixedly connected to the outer surface of the ventilation box 8, and the inner surface of the ventilation box 8 is provided with a fan 7.

[0027] The effect achieved by the entire embodiment 1 is that one of the two dust-proof nets 413 is a metal filter and the other is an activated carbon filter. When the construction site needs to be filtered, the device is moved to the specified position by the walking wheels at the bottom of the base 6, and then the electric telescopic rod 3 is started by the controller to move the driving end of the electric telescopic rod 3 upward or downward, thereby adjusting the height of the ventilation box 8. When the adjustment is completed, the fan 7 is turned on to speed up the circulation of air and improve the ventilation efficiency. Then, the larger impurities in the air are filtered through one of the dust-proof nets 413, and the tiny impurities and odors in the air are filtered through the other dust-proof net 413. When use is completed, the fan 7 can be turned off, and the push block 404 is pushed outward to move along the limit groove 412, thereby driving the card block 411 to move inward along the installation groove 410. The movable rod 409 and the spring 408 are moved to compress, so that the card block 411 is no longer engaged with the card slot 405 and moves to the inner wall of the installation slot 410, and the mounting bracket 403 can be pulled out from the slide slot 406 through the handle 402, which is convenient for cleaning and maintenance of the dustproof net 413. During installation, it is only necessary to insert the mounting bracket 403 along the slide slot 406. When it is fully inserted, release the push block 404. Under the restoring force of the spring 408, the card block 411 will be pushed out of the mounting slot 410, and the moving direction of the card block 411 is limited by the movable rod 409, so that the card block 411 will move to the card slot 405 and engage with the card slot 405, completing the installation of the mounting bracket 403, thereby facilitating the disassembly and installation of the mounting bracket 403, improving the convenience of maintaining the dustproof net 413, and ensuring the filtering effect of the dustproof net 413 on the air.

[0028] Embodiment 2, as Figure 1-Figure 6 As shown, the outer surface of the push block 404 is fixedly connected to a dustproof plate 407, and the top of the base 6 near both sides is fixedly connected to an electric push rod 1, the driving ends of the two electric push rods 1 are movably penetrated through the top of the base 6, and the driving ends of the two electric push rods 1 are fixedly connected to a support plate 5.

[0029] The effect achieved by the entire embodiment 2 is that when the base 6 moves to the specified position, the electric push rod 1 is started through the controller to move the two support plates 5 downward, so that the support plates 5 come into contact with the ground, thereby increasing the contact area of ​​the base 6 and making the device more stable when stopped, thereby reducing the displacement phenomenon. At the same time, the dustproof plate 407 is set so that the limit groove 412 can be closed by the dustproof plate 407 to prevent dust and impurities from entering the interior of the limit groove 412, thereby preventing dust and impurities from causing resistance to the block 411 when it moves.

[0030] Working principle: when it is necessary to filter the construction site, the device is moved to the specified position through the walking wheels at the bottom of the base 6, and the electric push rod 1 is started through the controller to move the two support plates 5 downward so that the support plates 5 are in contact with the ground, thereby increasing the contact area of ​​the base 6 and making the device more stable when it stops. Then, the electric telescopic rod 3 is started through the controller to move the driving end of the electric telescopic rod 3 upward or downward, thereby adjusting the height of the ventilation box 8. When the adjustment is completed, the fan 7 is turned on to speed up the circulation of air and improve the ventilation efficiency. Then, the larger impurities in the air are filtered through one of the dustproof nets 413, and the tiny impurities and odors in the air are filtered through another dustproof net 413. When use is completed, the fan 7 can be turned off, and the push block 404 is pushed outward to move along the limit groove 412, thereby driving the card block 411 to move inward along the installation groove 410, driving the movable rod 409 and the spring 408 is compressed so that the card block 411 is no longer engaged with the card slot 405 and moves to the inner wall of the installation slot 410, and the mounting frame 403 can be pulled out from the slide slot 406 through the handle 402, which is convenient for cleaning and maintenance of the dust screen 413. When installing, it is only necessary to insert the mounting frame 403 along the slide slot 406. When it is fully inserted, release the push block 404. Under the restoring force of the spring 408, the card block 411 will be pushed out from the installation slot 410 and released through the movable rod 409. The moving direction of the card block 411 is limited, so that the card block 411 will move to the card slot 405 and engage with the card slot 405 to complete the installation of the mounting frame 403, thereby facilitating the disassembly and installation of the mounting frame 403, improving the convenience of maintaining the dustproof net 413, and ensuring the filtering effect of the dustproof net 413 on the air. At the same time, when the dustproof plate 407 is set, the dustproof plate 407 can be used to close the limit groove 412 to prevent dust and impurities from entering the interior of the limit groove 412.

[0031] The wiring diagram of the electric push rod 1, the electric telescopic rod 3 and the fan 7 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the electric push rod 1, the electric telescopic rod 3 and the fan 7 are no longer explained in detail.
