Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figure 1-3, a dust removal and ventilation device for building HVAC engineering, including an air duct 1, a grille 2 is installed at the air inlet end of the air duct 1, and there are several ventilation holes on the grille 2. The two sides of the tube 1 are symmetrically installed with fixed plates, and a sliding rod 8 is fixedly connected between the two fixed plates on the same side. Each sliding rod 8 is slidably connected with a movable plate 3, and one side of the movable plate 3 is fixedly installed. There is a motor 4, a cleaning roller 5 is fixedly installed at the output end of the motor 4, a brush 6 is installed on the cleaning roller 5, and a mounting block 7 is installed on the other side of the cleaning roller 5 through a bearing, and the mounting block 7 is fixed on the other side. At the same time, a traction rope 10 is fixedly installed on the top of each movable plate 3 , and a pull ring 16 is fixedly installed at the bottom of each traction rope 10 .

Through the above technical solution, the motor 4 can be started during cleaning, and the motor 4 drives the cleaning roller 5 and the brush 6 on the cleaning roller 5 to rotate. At the same time, the operator can pull the pull ring 16 at the bottom at the same time, the position of the pull ring 16 is located in the place where the human hand can touch, when the pull ring 16 is pulled, the movable plate 3 moves downward under the action of the traction rope 10, and the movable plate 3 When moving downward, the spring 9 is squeezed, so that the cleaning roller 5 and the brush 6 between the movable plates 3 move, and other positions of the grille 2 are cleaned, and only need to be at a low position when cleaning The pull ring 16 can be pulled, no climbing operation is required, and the operation is simpler and safer.

Further, the brushes 6 on the cleaning roller 5 are arranged in multiple groups, and the position of each group of brushes 6 corresponds to the ventilation holes on the grille 2 one-to-one, that is, when the brushes 6 clean the grille 2 . , just in the ventilation hole of the grille 2, when cleaning it, it can effectively improve the cleaning efficiency of the grille 2.

It should be noted that, in the process of driving the motor 4, there is nothing but vibration, which makes the motor 4 jump. Therefore, during operation, when the operator pulls the pull ring 16, he must always pull the pull ring 16, and The movable plate 3 is restricted under the action of the tension force and the spring 9, which can reduce the vibration, or in other words, the motor 4 can not be started during cleaning, and the position of the brush 6 on the cleaning roller 5 can be changed directly by pulling the pull ring 16, and the grid 2 for cleaning, and the cleaning roller 5 can be reset by the spring 9, and the effect of cleaning the grid 2 can also be achieved after repeated operations.

Specifically, the connection between the grille 2 and the air duct 1 is hinged, and a first collection box 13 is provided on the outside of the grille 2. The first collection box 13 is fixed on the air duct 1 by magnetic attraction. A second collection box 14 is arranged on the inner side of the grille 2 , and the second collection box 14 is also fixed inside the air duct 1 by magnetic attraction.

Through the above technical solutions, the first collection box 13 and the second collection box 14 can effectively collect the dust generated in the cleaning process during cleaning, so as to facilitate unified processing of the dust in the later stage.

Specifically, a rotating rod 11 is installed inside the air duct 1 through a bearing, and a plurality of blades 12 are fixedly installed on the outer wall of the rotating rod 11 , and the plurality of blades 12 are arranged in a circular array with the axis of the rotating rod 11 as the center.

Through the above technical solution, when the air duct 1 is ventilated, the wind speed flows through the air duct 1. When encountering the blades 12 in the air duct 1, the blades 12 will have a certain hindering effect on the wind, and then the blades 12 are in the wind. It rotates under the action of the blade 12, and the wind also reduces the wind speed under the obstruction of the blades 12, and the wind noise can be effectively reduced after the wind speed is reduced.

When in use, the cleaning roller 5 and the brush 6 are driven to rotate by the motor 4 to clean the grille 2. At the same time, the traction rope 10 can be pulled during the cleaning process, so that the motor 4 and the mounting block 7 on the movable plate 3 can be pulled. Slide on the slide bar 8 to adjust the position of the cleaning roller 5, and clean other positions of the grille 2. During the cleaning process, you only need to pull the traction rope 10 on the ground, no climbing operation is required, and then The operation is more convenient and safer.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention , alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
