This device can effectively eliminate the phenomenon of incomplete sealing at the middle rain shield caused by maintenance, closure after ventilation, etc. However, it still has the following shortcomings:

[0003] The above-mentioned equipment achieves the effect of preventing the phenomenon of incomplete sealing. However, in some special situations, such as when harmful gas leaks or the concentration of harmful gas is too high, if the equipment is not opened and closed, unsafe air may enter the work area, which may affect the safety of the workers. Therefore, we provide a chain-operated ventilator. Utility Model Content

[0004] The purpose of this utility model is to provide a chain-operated ventilator. Through the opening and closing mechanism and the installation mechanism, it solves the problem of preventing the above-mentioned equipment from being poorly sealed after completion. However, in some special situations, such as when harmful gas leaks or the concentration of harmful gas is too high, if the equipment is not opened and closed, unsafe air may enter the work area, which may affect the safety of the workers.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a chain-type ventilator, including a wall, the inner wall of which is provided with a plurality of sliding grooves, and the inner wall of which is provided with an opening and closing mechanism.

[0007] The opening and closing mechanism includes a controller, the outer wall of which is fixedly connected to the inner wall of the wall. A motor plate is fixedly connected to the inner wall of the wall. A motor is fixedly connected to the outer wall of the motor plate at the end away from the controller. A rotating shaft is fixedly connected to the bottom output shaft of the motor via a coupling. The outer wall of the rotating shaft is rotatably connected to the inner wall of the wall. A sprocket is fixedly connected to the outer wall of the rotating shaft near the motor. A chain is driven to the outer wall of the sprocket. A second sprocket is driven to the inner wall of the chain at the end away from the sprocket. A second rotating shaft is fixedly connected to the inner wall of the second sprocket. The outer wall of the second rotating shaft is rotatably connected to the inner wall of the wall. Both the outer walls of the rotating shaft and the second rotating shaft are fixedly connected to bevel gears.

[0008] Furthermore, the inner wall of the wall away from the controller is rotatably connected to several rotating shafts, and the outer wall of the end of the several rotating shafts away from the controller is fixedly connected to a bevel gear.

[0009] Furthermore, the outer wall of the second bevel gear meshes with the outer wall of the second bevel gear, a baffle is fixedly connected to the outer wall of the end of the rotating shaft away from the second bevel gear, and an installation mechanism is provided on the inner wall of the wall.

[0010] Furthermore, the installation mechanism includes a filter plate, the outer wall of which is slidably connected to the inner wall of the wall, and a plurality of worm gears are rotatably connected to the inner wall of the filter plate.

[0011] Furthermore, a number of connecting blocks are fixedly connected to the outer wall of the filter plate near the controller, and a threaded rod is rotatably connected to the inner wall of the connecting blocks near the controller.

[0012] Furthermore, a worm gear is fixedly connected to the outer wall of the end of the threaded rod away from the controller, and the outer wall of the worm gear meshes with the outer wall of the worm.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a baffle. By starting the motor via a controller, the rotating shaft drives the baffle to rotate, thus ventilating the wall. The controller then shuts off the motor and restarts it, causing the aforementioned components to move in the opposite direction and return to their initial positions, closing the wall. This achieves stable opening and closing of the device, preventing the inability of the device to open or close and thus avoiding the impact on the indoor environment.

[0017] 2. This utility model, by setting a limiting block, first places the filter plate in the wall and positions the limiting plate in the sliding groove. Then, the worm gear is rotated, and the threaded barrel is moved stably by the telescopic rod. Next, the limiting plate is moved to the sliding groove near the controller. The limiting plate fixes the position of the device, preventing it from tipping over. This allows for the installation and removal of the filter plate, and enables convenient operation, preventing increased workload for workers due to complicated installation or removal operations.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The outer wall of the limit plate 307 is slidably connected to the inner wall of the wall 1. A telescopic rod 308 is fixedly connected to the outer wall of the filter plate 301 near the limit plate 307. The outer wall of the telescopic rod 308 is fixedly connected to the outer wall of the threaded barrel 306. The telescopic rod 308 enables the threaded barrel 306 to move stably, avoiding the problem of the threaded barrel 306 rotating during movement and preventing the device from being unable to maintain its position.

[0032] One specific application of this embodiment is:

[0033] When the operator needs to use the equipment, first place the filter plate 301 in the wall 1 and position the limiting plate 307 in the sliding groove 101. Then, rotate the worm gear 302, which drives the worm wheel 305 to rotate. The worm wheel 305 drives the threaded rod 304 to rotate, which in turn moves the threaded barrel 306. The threaded barrel 306 then moves the limiting plate 307 and the telescopic rod 308. The telescopic rod 308 ensures stable movement of the threaded barrel 306, preventing it from rotating during movement. Next, move the limiting plate 307 to the sliding groove 101 near the controller 201. The limiting plate 307 fixes the position of the device, preventing it from tipping over. This completes the installation process. Then, reverse the above steps to disassemble the device. Finally, start the motor via the controller 201. 203. Motor 203 starts rotating shaft 204. Rotating shaft 204 drives sprocket 205 to rotate, sprocket 205 drives chain 206 to rotate, chain 206 drives sprocket 207 to rotate, sprocket 207 drives rotating shaft 208 to rotate. The rotation of rotating shaft 204 and rotating shaft 208 causes bevel gears 209 at both ends to rotate. The rotation of bevel gears 209 drives bevel gears 211 at both ends to rotate, and the rotation directions of bevel gears 211 at both ends are opposite. Bevel gears 211 drive rotating shaft 210 to rotate, rotating shaft 210 drives baffle 212 to rotate. The rotation of baffle 212 puts wall 1 in a ventilated state. Then, controller 201 turns off motor 203, and then turns motor 203 back on. Motor 203 drives the above parts to move in the opposite direction and return to the initial position, so that wall 1 is in a closed state. Finally, filter plate 301 filters impurities in the air.
