[0002] In the nuclear industry, there is a need to treat liquid waste on the ground. In order to ensure personnel safety and improve efficiency, using robots for treatment is the best option. The robot needs to have devices to absorb and contain liquids and cannot cause secondary pollution.

[0003] At present, most nuclear industry cleaning robots adopt a structure of a wheel set or crawler chassis with a multi-axis robotic arm, with cleaning tools integrated at the end of the robotic arm or using a mechanical claw to clamp the cleaning tools. The control method is mostly remote control or semi-automatic. The huge chassis makes the robot large and inflexible. The multi-degree of freedom of the robotic arm has poor cleaning ability on the ground and is difficult to operate. The rest is a cabinet plus robot towing cable solution. The advantage is good cleaning effect, but the disadvantage is that cables, water pipes, etc. have certain requirements for the working distance. Secondly, the cabinet occupies too large an area and can only be operated in a fixed place. Summary of the invention

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A nuclear industry cleaning robot with magnetic adsorption capability comprises: a robot body, wherein each side of the robot body has a magnetic drive wheel, and the magnetic drive wheel is connected to a drive mechanism;

[0007] A laser radar is installed on the top of the robot body, and the laser radar is connected to a computer through a laser radar junction box;

[0008] A scraper is installed at the front end of the robot body, a water pump is installed at the root of the scraper, the water pump is connected to the water pump, and the scraper is raised and lowered by a scraper steering gear;

[0009] A mop and a mop receiving bracket are installed at the rear end of the robot body. The mop is rotated by a mop motor, and the mop is lifted and lowered by a mop lifting servo.

[0010] Furthermore, the scraper strip is equipped with a camera, which identifies the liquid and provides a field of view for image transmission.

[0011] Furthermore, the rear side of the robot body is provided with two auxiliary wheels to prevent the robot from tipping over.

[0012] Furthermore, the driving mechanism includes gear one, which is mounted on the steering wheel steering motor, and gear one is meshed with gear two, which is mounted on the magnet driving wheel.

[0013] Furthermore, the mop storage bracket wraps the mop with a garbage bag after the mopping operation is completed.

[0014] Furthermore, the robot body has a casing on its upper portion, and the casing contains a battery, a computer, and a control panel.

[0015] Furthermore, the scraper strip is a semicircular closed scraper strip, which is convenient for storing liquid.

[0016] The present invention may also include:

[0017] A cleaning method using the nuclear industry cleaning robot with magnetic adsorption capability, the method comprising:

[0018] During operation, the robot moves with autonomous navigation. It uses a camera to identify the contaminated area, and then uses a scraper servo to lower the scraper. After aiming at the contaminated area, the robot moves forward slowly and starts the water pump at the same time. The sewage is guided by the scraper and sucked into the waste liquid tank. After the suction is completed, the scraper is lifted, the water pump is turned off, and the robot continues to move forward. When the mop moves above the contaminated area, the mop lifting servo lowers the mop, and the mop motor drives the mop to rotate for cleaning.

[0036] Preferably, the scraper bar 28 in this embodiment is a semicircular closed scraper bar to facilitate storing liquid.

[0037] The adsorption method adopted by the robot in this embodiment is that the robot is equipped with a permanent magnetic adsorption module, which provides the robot with a stable and continuous adsorption force in the plane or vertical working space of the inner and outer walls of metal parts such as pressure vessels, industrial pipelines, and fan pipe piles. The adsorption force must have a relevant margin and allowance above the total weight of the machine and the maximum amount of the load it carries to ensure that the robot will not fall or other dangerous situations.

[0038] The robot in this embodiment can achieve omnidirectional movement. The robot adopts a steering wheel drive mode to achieve omnidirectional rapid movement and precise positioning on the working surface, reducing or completely eliminating the problems of inner and outer wheel difference and large turning radius caused by the differential steering mode often used in crawler or ordinary wheeled robots.

[0039] The robot motion mode in this embodiment is that the robot can realize multiple motion modes including inching mode, absolute motion, relative motion and trajectory planning, wherein trajectory planning includes common methods such as grid scanning, and trajectory design and entry and storage can be performed as needed to realize the motion route of a specific trajectory;

[0042] During operation, the robot moves in autonomous navigation. The robot uses the camera 26 to identify the contaminated area, and then uses the scraper servo 27 to lower the scraper 28. After aiming at the contaminated area, the robot moves forward slowly and starts the water pump 25 at the same time. The sewage is guided by the scraper 28 and sucked into the waste liquid tank. After the suction is completed, the scraper 28 is lifted, the water pump 25 is turned off, and the robot continues to move forward. When the mop 211 moves above the contaminated area, the mop lifting servo 214 lowers the mop 211, and the mop motor 29 drives the mop 211 to rotate for cleaning. At the same time, the robot's steering wheel steering motor 11 can rotate 90 degrees to make the two magnet driving wheels 13 collinear for S-shaped cleaning.

[0043] After cleaning is completed, the robot lifts up the mop 211, and the cleaning bag on the mop storage bracket 212 will cover the used mop 211, and the robot returns to the starting point after completing cleaning.

[0044] In this embodiment, before performing the cleaning operation, the robot can complete the mapping of the operation scene in advance.

[0045] The robot of the present invention can realize fully automatic autonomous operation, and can also be operated remotely by manual remote control. The previous state of the robot will be transmitted back to the computer, which is convenient for personnel operation.
