The operation of the above-described apparatus will be briefly described as follows. When the decompression generating means 78 is activated,
Fluid such as air in the decompression space 72 is discharged outside through the housing 4 and a hose (not shown), and
2 is depressurized as required. When the pressure in the decompression space 72 drops abnormally, the valve body 88 opens, and a fluid such as the outside air flows into the housing 4 through the space between the valve seat member 94 and the valve body 88, and thus the decompression space 72. Is maintained at a predetermined pressure set by the pressure adjusting means 86.
When the pressure in the pressure reducing space 72 is reduced, the surrounding fluid pressure such as the atmosphere acting on the apparatus main body 2 (particularly, the rotating body 6 acting as a pressure receiving member) due to the fluid pressure difference between the inside and the outside of the pressure reducing space 72 increases the right frame 154a and the left frame. 154b and wheels 15

Next, when the pressure reduction generating means 144 in the variable pressure setting means 122 is energized and the switching valve 148 is set to the first position, the pressure adjusting space 120 of the partitioning means 50 is depressurized through the switching valve 148. The fluid such as air in the pressure adjusting space 120 is discharged to the outside, and the pressure adjusting space 120 is also reduced in pressure as required. The pressure in the pressure adjustment space 120 has a great effect on the ground pressure of the partitioning means 50, and can be set, for example, as follows. That is, if the pressure Pa in the pressure adjustment space 120 is set to be smaller than the external Po and larger than the pressure Pb in the decompression space 72 (Po <Pa <Pb),
As can be understood from FIG. 1, the inner wall 5 of the partitioning means 50 is caused by the fluid pressure difference between the pressure adjustment space 120 and the decompression space 72.
6, the fluid pressure in the pressure regulating space 120 acting on
A force in a direction approaching the wall surface 48 acts on the contact portion 52 and is separated from the wall surface by an external fluid pressure acting on the outer wall portion 54 of the partitioning means 50 due to a fluid pressure difference between the outside and the pressure adjusting means 120. Is applied to the contact portion 52. Accordingly, the contact portion 52 of the partitioning means 50 is pressed against the wall surface 48 by the difference between the force in the direction approaching the wall surface 48 and the force in the direction away from the wall surface 48, and when the fluid pressure in the decompression space 72 is set relatively low. Also, the contact pressure of the contact portion 52 can be reduced. In order that the contact portion 52 of the partitioning means 50 does not substantially separate from the wall surface 48, the force in the direction approaching the wall surface 48 needs to be larger than the force in the direction separating from the wall surface 48. As will be understood from the above description, the pressure regulating space 12
By changing the pressure 0, it is possible to adjust the ground pressure of the contact portion 52 of the partitioning means 50 in a state where the pressure in the decompression space 72 is kept constant.
For example, when the pressure of the contact 20 approaches the external pressure such as the atmosphere, the force in the direction away from the wall surface 48 decreases, and the contact portion 52
When the pressure in the pressure adjustment space 120 approaches the pressure in the decompression space 72, the force in the direction approaching the wall surface 48 decreases, and the contact pressure of the contact portion 52 decreases relatively. .

When the electric motor 16 is energized in the suction state, the rotating body 6 is rotated with respect to the housing 4 as required because the frictional force between the wheels 158 and 164 and the wall surface 48 is large. Then, the contact portion 52 of the partitioning means 50 rotates while contacting the wall surface 48, and the wall surface 48 is cleaned by the action of the contact portion 52. Contact part 52
Since the plurality of grooves 71 are formed in the partition wall 50, the portions defining the grooves 71 in the partitioning means 50 effectively act on the wall surface 48 during rotation, and the cleaning effect of the wall surface 48 is also improved.
Further, the flow of the fluid passing through the groove 71 always occurs at the time of adsorption to the wall surface 48. Therefore, dust and the like generated during the cleaning operation are collected in the depressurized space 72 on the flow of the fluid and scattered outside. Inconvenience is also eliminated. Also, when the electric motor 156 is energized to rotate forward (or reverse),
The wheels 158 and 164 are rotated in a predetermined direction (or a direction opposite to the predetermined direction), and the apparatus main body 2 is moved along the wall surface 48 in FIG.
, The wall surface 48 is cleaned while moving to the left (or right). When the device main body 2 moves and the partitioning means 50 passes through a protrusion (or a concave portion) existing on the wall surface 48, the expandable and contractible portions of the outer wall portion 54 and the inner wall portion 56 expand and contract (or approach) in a direction away from the wall surface 48. Therefore, the seal between the contact portion 52 of the partitioning means 50 and the wall surface 48 is not broken. Further, since the inner wall portion 56 and the outer wall portion 54 of the partitioning means 50 are connected to the disc 30, respectively, even if the partitioning means 50 comes into contact with a relatively large projection, the projection can be easily turned without turning inside. Since the outer wall portion 54 and the inner wall portion 56 are provided with expandable and contractible portions, the contact portion 52 of the partitioning means 50 is relatively displaced in a direction approaching and separating from the wall surface 48, and Can be sufficiently followed.

It is also possible to provide the housing 4 with a dedicated surface treatment means for blast cleaning, painting, cleaning, etc. of the hull wall without substantially using the partition means 50 as a surface treatment means. In such a case as well, it is preferable to rotate the partitioning means 50 as described above when the apparatus main body 2 is moved, and thus the frictional force between the contact portion 52 of the partitioning means 50 and the wall surface 48 can be reduced.

After the electric motor 16 is deenergized, the pressurized fluid supply source 146 in the variable pressure setting means 122 is energized and the switching valve 1
48 is moved to the second position. Thus, the pressure adjusting space 120 of the partitioning means 50 is connected to the pressurized fluid supply source 146 via the switching valve 148,
A pressurized fluid, such as compressed air, is supplied to the pressure regulating space 120. When the device is used, the variable pressure setting means 122
The pressure adjusting space 120 may be depressurized or pressurized by constantly energizing the vacuum generating means 144 and the pressurized fluid supply means 146 and switching the switching valve 148. When the pressurized fluid is supplied to the pressure adjustment space 120, the pressurized fluid causes the outer wall portion 54 and the inner wall portion 56 to be supplied.
The extension part provided in the extension part. Thus, as will be easily understood by comparing FIG. 3 and FIG. 4, the above-mentioned extension of the two expandable portions causes the rotating body 6 (the housing 4, the right frame 154 a, and the left frame 154 to be integrally formed therewith).
b and wheels 158 and 164) are pushed up in a direction away from wall surface 48, and wheels 158 and 164 move away from wall surface 48. Thereafter, the electric motor 16 is slightly rotated. Thus, since the partitioning means 50 comes into contact with the wall surface 48 and the relative rotation between the two is prevented, the housing 4, the right frame 154a, the left frame 154b, and the wheels 158 and 164 are moved relative to the partitioning means 50 and the disk 30. Is rotated as required, and thus the direction of movement of the apparatus main body 2 is switched. As described above, the switching of the moving direction of the apparatus main body 2 is achieved by the relative rotation of the housing 4 (the wheels 158 and 164 mounted thereon) with respect to the partition means 50, and therefore, when the direction is changed, the wall surface 48 is changed. There is no inconvenience such as scratching. After changing direction,
The switching valve 148 is positioned at the first position to reduce the pressure in the pressure adjustment space 120 as required.
May be applied to rotate the rotating body 6, whereby the cleaning operation of the wall surface 48 is resumed.
