And a traveling means installed in the pressure receiving main body. In such an apparatus, when the inside of the depressurized region is depressurized by the depressurizing means, the device is adsorbed on the wall surface by the surrounding fluid pressure due to the fluid pressure difference inside and outside the depressurized region. And when the running means is activated,
The device is moved along the wall while adsorbed. Thus, such a device can adsorb to and move along a wall surface. However, the above-described apparatus has the following disadvantages to be solved. That is, with the movement of the device, the partition wall also moves with respect to the wall surface while being in contact with the wall surface.During such movement, dirt such as degraded coating film pieces, rust, scales and the like adhered to the wall surface. It was peeled off by the scraping action, and the dirt was scattered around without being collected in the decompression region, and there was a risk of contaminating the air when used in the air and water when used in the water. Further, in the above-mentioned apparatus, in the apparatus provided with a device for peeling the deteriorated coating film by injecting ultra-high pressure water toward the wall surface inside the depressurized region, the peeled coating film piece is separated by the partition. There is a problem that the resin leaks from the contact portion between the walls and adheres to the processing surface, thereby deteriorating the processing quality.

る。Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. First
3 to 3, the illustrated apparatus includes a pressure receiving body 2 formed of a rigid or semi-rigid material such as steel. The pressure receiving body 2 may have an appropriate shape, but in the specific example shown in the drawing, the pressure receiving body 2 has a shape in which an annular plate facing the wall surface W, that is, a lower wall 6 is welded around an opening of a substantially cylindrical box. Outwardly projecting support members 12 and 14 are fixed to both opposing portions of the side wall of the pressure receiving main body 2, and support frames 16 and 18 are further fixed to the support members 12 and 14. Two wheels 22a and 22b are rotatably mounted on one (lower in FIG. 1) support frame 16. The support frame 16 is further provided with an electric motor 24 constituting a travel drive source. The electric motor 24 is preferably capable of rotating in both directions and is drivingly connected to the wheels 22a and 22b via suitable transmission means such as a chain 26 and a sprocket to rotate the wheels 22a and 22b. The other (upper in FIG. 1) support frame 18 is also rotatably mounted with two wheels 30a and 30b. The support frame 18 is also provided with an electric motor 32 constituting a traveling drive source. The electric motor 32 is preferably capable of rotating in both directions, and the wheels 30a are provided via appropriate transmission means such as a chain 34 and a sprocket. And 30b
And rotationally drives the wheels 30a and 30b. These wheels 22a, 22b, 30a and 30b constitute running means for moving the device along the wall surface W, and in a specific example, as will be described in detail later, the pressure receiving body 2
Is pressed against the wall surface W by the surrounding fluid pressure acting on it, and is brought into contact therewith. In addition, in the specific example, four wheels are used as the traveling means.
Individual or five or more wheels may be used, and two or more endless trucks known per se may be used in place of the wheels. Referring to FIG. 3 and FIG. 5, a partition wall 36 is provided adjacent to the opening 8 of the lower wall 6 of the pressure receiving main body 2. Regarding the configuration of the partition wall 36, two flange-like mounting portions are connected to the lower wall 6, and the annular lip portion 4 is formed.
8b is disposed close to and parallel to the wall surface W,
The contact portion 48a on the outer peripheral portion of the lip portion 48b is
In the specific example, the partition wall 36 defines a decompression region 50 in cooperation with the pressure receiving main body 2 and the wall surface W. In addition, there is an extension 48c extending outward from the contact portion 48a toward the outermost peripheral portion and away from the wall surface W. The partition wall 36 is formed of a non-breathable and relatively flexible material such as polyurethane rubber, so that the partition wall 36 is elastically deformed by a relatively small force. It can be freely deformed by imitating. The decompression space 50 defined by the pressure receiving main body 2, the wall surface W, and the partition wall 36 is communicated with the decompression generating means 64. In a specific example, a connection portion 10 a is provided on the side wall 10 of the pressure receiving main body 2, and one end of a flexible suction hose 66 is connected to the connection portion 1.
0a, and the other end is connected to a decompression generating means (not shown) via a separator (not shown). The decompression generating means discharges the fluid from the decompression region 50 and
It may be a well-known device for reducing the pressure inside 0, for example, when the above device is used in the atmosphere, an exhaust pump or an ejector can be used, and when the above device is used, for example, in water or in the sea, A drain pump or the like can be used. Although not shown, it is preferable to provide a vacuum breaker in order to prevent the pressure in the pressure reducing region 50 from being reduced to a predetermined value or more. In the device according to the invention, as shown in FIGS.
It is important that a plurality of thin plates 70 are attached or welded to at least the contact portion 48a. Although not shown, it is important that a thin plate provided with a plurality of grooves 81 communicating the inside and outside of the decompression region 50 is attached or welded to the contact portion 48a of the partition wall 36. In a specific example, the thin plate is desirably a material having abrasion resistance and a low coefficient of friction. For example, a fluororesin or ultra-high-molecular polyethylene can be applied. As described above, the apparatus is used to remove radioactive corrosion products, so-called cladding, attached to the walls and floors of various swimming pools in nuclear facilities in the air or water, to clean algae attached to the bottom of ships, and to remove spherical gas. It can be conveniently used for a coating film peeling operation by ultra-high pressure water injection from a holder or the like. Next, the operation and effect of the above-described device will be described. When the reduced pressure generating means operates, the fluid in the reduced pressure area 50 (for example, air when used in the atmosphere,
Further, for example, when used in water, water is discharged to the outside through the suction hose 66, and thereby the pressure in the decompression region 50 is reduced as required. The surrounding fluid pressure acting on the pressure receiving body 2 due to the fluid pressure difference between the inside and outside of the pressure reducing region 50 is substantially from the pressure receiving body 2 to the support frames 16 and 1.
8, and transmitted to the wall surface W via the wheels 22a, 22b, 30a and 30b, whereby the device is attracted to the wall surface W. On the other hand, the surrounding fluid pressure acting on the partition wall 36 due to the fluid pressure difference between the inside and outside of the decompression region 50 causes the partition wall 36 to be biased toward the wall surface W, and the contact portion 48
a so as to bring a into contact with the wall surface W. Accordingly, the contact portion 48a of the partition wall 36 comes into contact with the wall surface W, and the wall surface can be cleaned by the contact pressure between the contact portion 48a and the wall surface W. In the suction state, the decompression region 50 is depressurized as required, while a plurality of substantially rectangular thin plates 70 are attached to the contact portion 48a of the partition wall 36 at intervals in the circumferential direction. A plurality of grooves 68 are formed so that a fluid flow from outside through the grooves 68 and into the decompression region 50 is substantially constantly generated. Therefore, the dirt (degraded coating film pieces, rust, scale, etc.) peeled off near the contact portion 48a of the partition wall 36 outside the decompression region 50 due to the movement of the device of the present invention rides on the flow of the above-described fluid and the grooves 68. The dirt is transferred into the decompression area 50 through the inside, and thus, the dirt generated during cleaning is reliably prevented from scattering around. In the specific example, the presence of the groove 68 generates a flow inward of the partition wall 36 in the radial direction, thereby preventing the dirt from scattering. Decompression area 5
The contaminants transferred into the chamber 0 are conveyed to the separator (not shown) through the suction hose 66 together with the liquid in the decompression region 50 by the action of the decompression means (not shown). The liquid is separated as required, and the separated clean liquid is discharged to the outside. Next, although not shown, a thin plate having a plurality of grooves may be attached or welded. As will be easily understood, the electric motors 24 and 3
When the wheels 2a and 22b and the wheels 30a and 30b are driven to rotate in the same direction by operating the device 2, the device goes straight along the wall surface W, and when the wheels 22a and 22b and the wheels 30a and 30b are driven to rotate in the opposite directions, The device is rotated about its central axis and directed in a desired direction. As described above, one specific example of the device configured according to the present invention has been described. However, the present invention is not limited to such specific example, but can be applied to a device that can be adsorbed on various wall surfaces. That is, for example, as disclosed in Japanese Patent No. 1323843, one end of a partition wall is connected to a pressure receiving body, and the pressure receiving body is equipped with a surface treatment means such as an ultra-high pressure water injection means or a polishing material projection means, The present invention can also be applied to an apparatus in which the surface treatment means treats the wall surface in the reduced pressure area as required. In the apparatus of this embodiment, foreign substances such as degraded coating film pieces separated inside the decompression region are effectively suctioned and collected without leaking to the outside of the decompression region by the action of the flow from the outside to the inside of the decompression region. be able to.

る問題を解決することができる。According to the present invention, the following effects are achieved. (1) The contact portion that contacts the wall surface of the partition wall is provided with a plurality of grooves that communicate inside and outside the decompression region. Even if the thin plate piece that forms the groove is worn by wear, it can be easily pasted or welded again. (2) Since it is extremely easy to appropriately set the number and the cross-sectional area of the grooves, it is possible to set the amount of fluid passing through the grooves per unit time to a desired amount, thereby sucking dirt. The ability to collect can be set appropriately. (3) In the method of forming grooves, it is unnecessary and extremely simple to process a molding die, and the manufacturing cost is greatly reduced. (4) A flow is generated inward of the partition wall in the radial direction,
The fluid outside the reduced pressure region flows into the reduced pressure region through the groove. Thus, dirt is prevented from scattering around. Further, it is possible to solve the problem that the peeled coating film piece leaks from the contact portion between the partition wall and the wall surface and adheres to the processing surface, thereby deteriorating the processing quality.
