Description

Technical Field

[0001] The utility model relates to the technical field of maintenance equipment for inspection robots, and in particular to a circulating closed dust removal device integrating blowing and suction. Background Art

[0002] At present, intelligent inspection robots have been widely used in the field of safety supervision to replace manual inspections in special scenarios. In particular, rail inspection robots are usually used in industrial environments such as coal mines, coal-fired power plants, and metallurgy to replace manual inspections. Since there is a lot of dust in industrial environments such as coal mines, coal-fired power plants, and metallurgy, dust easily adheres to the surface of rail inspection robots or enters the interior of rail inspection robots, thus affecting the work of rail inspection robots and even causing damage to them. Therefore, a solution is urgently needed.

[0003] For example, a Chinese utility model patent with publication number CN218133766U proposes an external dust removal device for a coal transport trestle inspection robot, which uses a motor to drive the rotating shaft to rotate, and connects the bottom surface of the rotating shaft to a connecting plate, and connects the connected bottom surface to a fixed frame on the left and right, and adds an air jet pipe inside the fixed frame, and adds a fixed box on the bottom surface of the cross plate that is movably connected to the rotating shaft, and uses an air pump to ventilate the fixed box, and uses the side ports on the outer surface of the rotating shaft and the through holes inside the rotating shaft to pass the high-pressure air into the air jet pipes on both sides, thereby ensuring that the surface of the robot between the two sets of air jet pipes below is dusted during rotation.

[0004] However, the above dust removal device has the following defects: First, the above scheme places the robot body in the coal conveying environment for external jet dust removal, and there is still a certain concentration of coal ash in the coal conveying environment. Direct jet cleaning of the robot body is likely to result in incomplete dust removal, and the coal ash will still fall back on the robot body, causing secondary pollution. Second, the dust removal range of the above dust removal device is limited, and dust removal is limited to the range within the rotating fixed frame. Robots larger than the rotation range are difficult to be effectively dusted. For example, it is difficult to effectively remove dust from the long rail-mounted inspection robots commonly used in coal conveying corridors. Utility Model Content

[0030] The cleaning assembly 2 includes a cleaning box 21, an air nozzle 22 and a dust hood 23, wherein the air nozzle 22 and the dust hood 23 are both installed inside the cleaning box 21, and the outlet of the fan 1 is connected to the inlet of the air nozzle 22, and the outlet of the dust hood 23 is connected to the inlet of the dust collecting assembly 3;

[0031] The cleaning assembly 2 is hung on the inspection track 4 through the cleaning box 21, and the side wall of the cleaning box 21 is provided with a closed door 211, and the closed door 211 is used to open and close the cleaning box 21, and the cleaning box 21 is used to accommodate the inspection robot to be dusted.

[0032] In order to achieve effective dust removal for the inspection robot and avoid secondary pollution of the inspection robot, this technical solution proposes a closed-loop dust removal device with integrated blowing and suction, such as Figure 1-4 As shown, it includes a fan 1, a cleaning component 2 and a dust collecting component 3 which are connected end to end in sequence through a pipeline, wherein the cleaning component 2 includes a sealed cleaning box 21, an air nozzle 22 for blowing away dust accumulated on the inspection robot, and a dust hood 23 for sucking away dust accumulated inside the cleaning box 21.

[0033] The working process of the circulating closed dust removal device of this scheme is as follows: (1) Open the closed door 211, and let the inspection robot (not shown in the figure) to be dusted on the inspection track 4 walk to the inside of the cleaning box 21, and then close the closed door 211; (2) Start the fan 1, so that the high-pressure airflow generated by the fan 1 can enter the inside of the cleaning box 21 through the pipeline, and spray to the inspection robot to be dusted through the jet pipe 22; further, the inspection robot can also move back and forth inside the cleaning box 21 so that its whole body is evenly sprayed with the high-pressure airflow to complete the surface cleaning of the robot in all directions; (3) Under the dust suction effect of the dust hood 23, the dust raised by the robot in the cleaning room 21 by the high-pressure airflow is sucked out, and the dust is collected by the dust collection component 3 through the dust hood 23 with the airflow; (4) After the dust removal is completed, open the closed door 211 again, and let the inspection robot (not shown in the figure) to be dusted on the inspection track 4 walk to the outside of the cleaning box 21, and complete the dust removal of the inspection robot.

[0034] Since the fan 1, cleaning component 2 and dust collecting component 3 in this solution are connected end to end through the pipeline, after the fan 1 is started, an internal closed circulating airflow is formed between the fan 1, cleaning component 2 and dust collecting component 3, and the internal airflow with dust after dust removal is collected in the dust collecting component 3, which is conducive to avoiding the dust raised in the air from falling back on the robot and causing the dust removal to be incomplete. In addition, through the setting of the dust hood 23 and the dust collecting component 3, the internal gas can be effectively sucked out in time and discharged to the inside of the dust collecting component 3, and the dust collecting component 3 can be cleaned when it is full of dust, which is conducive to ensuring the normal operation of the fan 1 and extending its service life.
