Description

Technical Field

[0001] The utility model belongs to the technical field of control box cleaning, and in particular relates to an elevator control box cleaning device. Background Art

[0002] The elevator control box is a device used to control the operation of the elevator. It is usually placed in the elevator machine room. The control cabinet of the elevator without a machine room is placed in the shaft. The control box is composed of a sheet metal frame structure and bolt assembly. The sheet metal frame has a uniform size and can be easily hung and removed with plastic pins. The front panel is equipped with a rotatable pin hook to form a lockable rotating door so that all components installed in the control cabinet can be accessed from the front, so that the control cabinet can be installed close to the wall.

[0003] During the long-term use of the elevator control box, a large amount of dust will remain on its surface. In order to reduce the adhesion of dust, maintenance personnel are required to clean the elevator control box regularly to reduce the adhesion of dust on electronic components. Most maintenance personnel use a brush to clean the contaminated dust to reduce the adhesion of dust. During the cleaning process, some dust will float in the air, and the floating dust will fall onto the components again, which will cause the temperature of the components to rise, leading to the failure of the cleaning work.

[0004] Therefore, how to collect the dust generated when cleaning the elevator control box is a problem to be solved at present. Utility Model Content

[0005] The purpose of the utility model is to provide an elevator control box cleaning device to solve the above-mentioned problems existing in the prior art.

[0006] Technical solution: An elevator control box cleaning device, comprising:

[0007] A box body, a plurality of components disposed in the box body, and a cleaning assembly located on the top of the box body;

[0008] The cleaning assembly includes a mounting shell fixedly mounted on the top of the box body, a driving part located in the mounting shell, a hose provided on the mounting shell, a movable shell connected to the other end of the hose, and a cleaning part provided on the movable shell;

[0009] The driving part includes a mounting seat arranged in the mounting shell, a fan located on the mounting seat, a filter screen arranged at an air inlet end of the fan, a connecting column connected to the filter screen, and a dust collecting cover located at the bottom of the connecting column;

[0010] The dust collecting cover is hinged to the mounting shell, and the air outlet end of the fan is communicated with the outside.

[0011] In a further embodiment, the filter screen is provided with a plurality of connecting holes in the circumference thereof.

[0012] In a further embodiment, the filter screen is a truncated cone structure, and the diameter of the filter screen gradually decreases in a direction away from the fan, and there is a predetermined angle between the filter screen and the mounting shell.

[0013] In a further embodiment, the connection between the hose and the mounting shell is located above the filter screen;

[0014] During adsorption, the air is flowed by the fan, so that the dust enters the installation shell and falls onto the dust collecting cover under the influence of its gravity.

[0015] In a further embodiment, the cleaning part includes a cleaning motor and a transmission shaft mounted on the movable shell, a plurality of bristles arranged on the transmission shaft, and a transmission part for connecting the output end of the cleaning motor with the transmission shaft.

[0016] In a further embodiment, the transmission part includes a driving wheel arranged at the output end of the cleaning motor, a transmission wheel sleeved on the transmission shaft, and a transmission belt for connecting the driving wheel and the transmission wheel.

[0018] The dust collecting cover is connected to the mounting shell through a limiting block and a limiting hole.

[0019] Beneficial effect: The utility model relates to an elevator control box cleaning device. In order to collect dust generated when cleaning the elevator control box, a cleaning component is provided in the device. Through the provided cleaning part, the dust on the components or the inner wall of the cabinet can be separated from the components and the cabinet by the bristles in the cleaning part. Then the fan starts to work, and the moving fan causes the gas in the installation shell to flow. Since the hose connects the installation shell and the movable shell, the hose will generate negative pressure in the movable shell, and the negative pressure generated can absorb the dust brushed by the bristles, and the dust enters the installation shell along the hose. Since the filter screen is convex The filter has a platform structure, and its diameter gradually decreases as it moves away from the fan. As a result, the dust can fall onto the dust collecting cover under the influence of its own gravity. Then, the gas can be filtered for the second time when passing through the filter, so that the dust adheres to the filter. The gas can then be discharged to the outside from the air outlet of the fan, thereby completing the cleaning of the inside of the control box. At the same time, a negative pressure can be generated in the movable shell through the arranged driving part, so that the floating dust can be collected, thereby preventing the floating dust from falling onto the components again, thereby completing the cleaning of the inside of the control box and collecting the dust at the same time.

DETAILED DESCRIPTION

[0024] After research and analysis by the applicant, the reason for this problem (floating dust will fall onto components again, which will cause the temperature of components to rise, leading to the failure of cleaning work) is that maintenance personnel mostly use brushes to clean the contaminated dust to reduce dust adhesion. During the cleaning process, some dust will float in the air, and then the floating dust will fall onto components again. This invention is for.

[0025] A cleaning device for an elevator control box includes: a box body 1, components 2, a cleaning assembly 3, a mounting shell 31, a hose 32, a movable shell 33, a driving part 34, a mounting seat 341, a filter screen 342, a connecting column 343, a dust collecting cover 344, a cleaning part 35, a cleaning motor 351, a driving wheel 352, a transmission belt 353, a transmission shaft 354, bristles 355, and a transmission wheel 356.
