Abstract

PURPOSE:To especially clean a large space chamber easily according to an unmanned system by constituting the title robot of the first running stand provided with a filter, a blower and an air blow-out nozzle, and the second running stand provided with a filter, a blower and an air suction port and running so as to follow the first running stand. CONSTITUTION:When the first running stand 13 is moved, air is blown out from an air blow-out nozzle 26. By this method, the dust adhered to the floor surface 11, ceiling surface 13, wall surface, pipings or the like in a chamber 10 is allowed to whirl up into the air. Then, the second running stand 14 is moved so as to follow the first running stand 12 and the dust scattered by the first running stand 12 is sucked from the air suction port 36 of a duct 34. By this method, the dust is removed by the filter 38 of the second running stand 30 and the purifying degree in the chamber 10 is gradually enhanced. Especially, in the case of a large space chamber, by allowing one set of the running stands to repeatedly go round, dust concn. distribution is uniformized and a high purifying degree is easily achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning robot, and particularly to a cleaning robot suitable for cleaning large-capacity spaces such as turbine rooms of nuclear power plants and the like.

[Conventional technology]

Conventionally, when cleaning large-capacity buildings such as nuclear reactor buildings, relatively large-sized dust accumulated on the floor was removed using a vacuum cleaner, and dust adhering to the walls was wiped with a rag or chemical rag. I have to.

[Problem that the invention seeks to solve]

However, the conventional cleaning method described above uses a vacuum cleaner, rags, chemical rags, etc., and is carried out by human labor.
Nuclear reactor buildings, etc., which have large spaces and complicated piping systems, have the disadvantage of requiring a large number of cleaning workers.

Also, among the dust particles in the air, large particles accumulate on the floor and can be removed relatively easily with a vacuum cleaner, but small particles, especially those with a diameter of about 1 μm, accumulate on the floor. To sediment<<
However, it has the disadvantage that it cannot be completely removed because it remains suspended in the air for a long time. In addition, it takes a long time to wait for such floating dust to accumulate on the floor surface, resulting in a disadvantage that the cleaning time becomes longer.

The present invention has been made in view of the above circumstances, and an object of the present invention is to propose a cleaning robot that can perform cleaning unmanned without requiring as many cleaning workers as in the past.

[Means for solving problems]

The present invention includes a first traveling platform provided with a filter, a blower, and an air blowing nozzle, and a second traveling platform provided with a filter, a blower, and an air suction port and traveling following the first traveling platform. It is characterized by consisting of.

[Effect]

In the present invention, the first traveling frame first travels, air is blown out from the air blowing nozzle mounted on the first traveling frame,
Dust attached to floors, ceilings, and walls is scattered and raised.

Next, a second traveling gantry travels following the first traveling gantry, and air is sucked from an air suction duct mounted on the second traveling gantry.

The air sucked from the air suction duct contains dust scattered by the first traveling frame, and this dust is removed by a filter provided on the second traveling frame. In this way, the first traveling frame and the second traveling frame can be run inside the room to remove dust.

[Embodiments] Preferred embodiments of the cleaning robot according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a first traveling frame 12 running on a floor surface 11 of an interior 10 of a nuclear reactor building, etc., and this eleventh traveling frame 1.
A second traveling frame 14 is shown which follows the vehicle.

The structure of the first traveling frame 12 is shown in detail in FIG. 2, and the vehicle body 16 is able to move freely on the floor 11 via wheels 18,18. A duct 20 is erected on the vehicle body 16, and a blower 22 is connected to the duct 20. This blower 22
is adapted to supply air into the intake duct 20 via a filter 24. A plurality of air blowing nozzles 26, 26, 26 are provided in the upper part of the duct 20.

Therefore, when the blower 22 is activated, the nozzle 26.26.26
Air is blown out from the ceiling, blowing up dust that has adhered to the ceiling, walls, etc.

In FIG. 3, the second traveling frame 14 is shown.

The second traveling frame 14, like the first traveling frame 12, has wheels 32, 32 at the lower part of the vehicle body 30, and can move freely on the floor surface 11. A duct 34 is provided upright on the vehicle body 30, and a plurality of air suction ports 36, 36, 36, 36 are formed in the duct 34. Furthermore, a blower 40 is attached to this duct 34 via a filter 38. Therefore, the blower 4
0 is activated, air is sucked from the air suction port 36 of the duct 34, dust is removed by the filter 38, and then clean air is released into the room.

The first traveling pedestal and the second traveling pedestal can be moved freely by radio, or can be moved along a predetermined track by means of a guide cable laid in advance on the floor 11, or the like.

A preferred embodiment of the cleaning robot according to the present invention configured as described above is as follows. First, when the first traveling frame 12 moves as shown in FIG.
, dust adhering to the ceiling surface 13, walls, and piping is thrown up into the air. Further, the second traveling pedestal 14 moves following this first traveling pedestal 12, and the first traveling pedestal 12 moves.
The dust scattered by the air suction port 3 of the duct 34 is
Inhaled from 6. As a result, dust is removed from the second traveling frame 3.
0 filter 38, and the cleanliness of the room gradually increases. Particularly in the case of a large room, the - group of traveling frames repeatedly circulates, thereby making the dust concentration distribution uniform and easily reaching a high degree of cleanliness.

According to the embodiment, the first traveling frame 12 and the second traveling frame 14 can be freely moved to every corner of the room, so that the corners of the room and the lower part of the piping, which could not be sufficiently removed in the past, can be moved freely. It is possible to remove dust such as

FIG. 4 shows a second embodiment, in which a first traveling frame 12 and a second traveling frame 14 are connected.
