In these figures, reference numeral 1 designates a housing in which an opening 2 which expands outward in the vertical direction is provided.
Although it is formed of a thin metal plate, it may be formed of a resin molded product. On the side wall of the housing 1 opposite to the opening 2, a flying body carrier pipe 4 made of metal or resin and having an inner diameter through which the flying body 3 can pass is mounted in communication.

The flying body 3 has a diameter of 10 mm to 30 m.
Although it is a sphere of about m and formed of a solid sponge body, it may be formed of a hollow sponge body or a hollow rubber body. Further, it may be one having a soft periphery and a hard core body enclosed therein, and in the case of a sponge body, it may be an open cell system having water absorbability or a closed cell system having no water absorbency. Further, the shape is not limited to a sphere, and may be a cube, a rectangular parallelepiped, or a plurality of protrusions formed.

A well-known blower (not shown) for supplying compressed air to the projectile carrier pipe 4 is connected to the side of the projectile carrier pipe 4 opposite to the mounting portion to the housing 1. Further, below the vicinity of the mounting portion of the flying body transport pipe 4 to the housing 1, a flying body storage box 5 in which a large number of flying bodies 3 are stored is provided. Then, between the flying object storage box 5 and the flying object transport pipe 4, a lower end is inserted into the flying object storage box 5 and an upper end is communicatively attached to a lower side wall of the flying object transport pipe 4. The body supply pipe 6 is vertically provided. The flying body supply pipe 6 is the same as the flying body transport pipe 4. In addition, the flying body supply pipe 6
The well-known means for supplying the liquid in a mist state (not shown).
No) is connected.

Between the lower side wall of the housing 1 near the opening 2 and the front side wall of the flying object storage box 5, an arc-shaped flying object return which communicates the housing 1 and the flying object storage box 5 with each other. The pipe 7 is attached. The flying body return pipe 7 is also similar to the flying body transport pipe 5. A soft seal member 8 such as rubber is attached to the periphery of the opening 2 of the housing 1. The seal member 8 is not always necessary.

A moving table 9 for holding and moving the flying object storage box 5 is provided below the flying object storage box 5. The moving table 9 is composed of a pantograph section 10 for vertically moving the flying object storage box 5 and a wheel section 11 for horizontally moving the flying object storage box 5. The flying object storage box 5 may not be mounted on the moving table 9 but may be directly held by an operator, or may be mounted on a moving means such as an automobile.

Thus, the seal member 8 in the opening 2 of the housing 1
When the blower is operated in a state where the blower is close to or slightly in contact with the surface to be cleaned 12, the compressed air supplied by the blower passes through the projectile carrying pipe 4 and goes along the inner wall of the housing 1 to the surface to be cleaned 12 Is injected into. Then, on the same principle as that of the “fog blow”, negative pressure is generated in the projectile supply pipe 6, an ascending air current is generated in the projectile supply pipe 6, and accordingly, the projectiles 3 in the projectile storage box 5 are It moves upward in the projectile supply pipe 6 and is supplied into the projectile transport pipe 5.

The flying object 3 supplied into the flying object carrying pipe 5 moves horizontally in the flying object carrying pipe 5 at a high speed by the compressed air supplied from the blower, and the opening of the housing 1 is opened. 2 collides with the surface 12 to be cleaned. Then, due to the impact force of the flying object 3 at the time of collision, the wall surface 1 to be cleaned 1
The contaminant is peeled off from 2 and removed.

The flying object 3 after colliding with the surface 12 to be cleaned is
It drops downward, passes through the flying body return pipe 7, and is collected in the flying body storage box 5. In addition, stop the blower,
When the supply of compressed air is stopped, the projectiles 3 in the housing 1 are all collected in the projectile storage box 5 by gravity.

Next, a second embodiment will be described with reference to FIG. In this embodiment, a liquid storage can 14 for storing water 13 is mounted in the flying body supply pipe 5 as a means for supplying a liquid (more specifically, water) in a spray form. Then, the liquid storage can 14 and the flying body supply pipe 5
A liquid suction thin tube 15 is attached between the above and the above. Also,
The bottom side portion of the flying body return pipe 7 is formed in a mesh shape of a mesh through which the flying body 3 cannot pass. The bottom of the flying object storage box 5 may be formed in the mesh shape of the mesh as described above.

As described above, when the liquid storage can 14 and the liquid suction thin tube 15 are provided, the flying body transport pipe 4 is provided.
As compressed air passes through the inside of the liquid suction thin tube 15, a negative pressure is generated in the liquid suction thin tube 15 and an ascending air current is generated in the liquid suction thin tube 15 according to the same principle as that of the “mist blowing”. The water 13 in the inside moves upward in the liquid suction thin tube 15 and is sprayed in the flying body transport pipe 5 in the air feeding direction. Then, the flying object 3 contains a little moisture, and the cleaning effect is improved.

If the bottom side of the flying body return pipe 7 and the bottom of the flying body storage box 5 are formed in a mesh net 17, the contaminant 16 removed from the surface 12 to be cleaned is the net. It falls from 17 and is discharged to the outside.

The flying body supply pipe 5 may be mounted on the lower portion of the flying body transport pipe 4, or may be mounted on the lateral portion or the upper portion of the flying body transport pipe 4.

[0022]

According to the present invention, when compressed air is supplied to the projectile carrier pipe, the inside of the projectile supply pipe becomes negative pressure,
The flying object in the flying object storage box is sucked up into the flying object transport pipe through the flying object supply pipe. Then, the sucked flying object is conveyed into the housing by the compressed air, and is impacted against the portion to be cleaned through the opening of the housing, and the contaminants on the portion to be cleaned are separated and removed by the flying object. It Then, the flying object that is abutted against the portion to be cleaned is collected in the flying object storage box through the flying object return pipe.
Therefore, the entire device can be manufactured compactly and at low cost.

Further, since the flying object is formed of a member that does not mechanically deform the portion to be cleaned when it comes into contact with the portion to be cleaned, when the portion to be cleaned is brought into contact with the portion to be cleaned. Only the contaminants can be peeled off and removed without damaging the cleaning portion.

Further, since the portion to be cleaned can be automatically cleaned, it is not necessary to remove the contaminants with a brush or the like while discharging water to the portion to be cleaned, which is efficient and economical.
If a soft flying object such as rubber or sponge is used, there is no possibility of damaging the side wall.

Furthermore, since high-pressure water is not jetted into contact with the side wall by the water gun, there is no possibility of damaging the weak side wall.
