The device disclosed in Japanese Laid-Open Patent Publication No. 2000-242242 has been proposed. The above-mentioned device includes a pressure receiving body formed of a rigid or semi-rigid material, a partition wall that cooperates with the pressure receiving body and the wall surface to define a decompression region, and a fluid is discharged from the decompression region to decompress the decompression region. And a traveling means installed on the pressure receiving main body, and a surface treatment means mounted on the pressure receiving main body and projecting, for example, a polishing material on the wall surface in the pressure reducing area.

の作業を施すことができる。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. Then, when the traveling means is operated, the device is moved along the wall surface while being sucked. Therefore, the apparatus as described above can be attracted to the wall surface and can be moved along the wall surface, and the wall surface can be subjected to a desired operation such as cleaning by the surface treatment means provided during the movement.

That is, as the device moves, the partition wall also moves with respect to the wall surface while being in contact with the wall surface, but during such movement, dirt such as deteriorated coating pieces, rust, and water stains attached to the wall surface scrapes the partition wall. There is a risk that it will be peeled and removed by the action, and those stains will scatter to the surroundings without being collected in the depressurized area, contaminating the atmosphere when used in the atmosphere and water when used in the water.

領域内に回収することは可能である。By the way, Japanese Patent Publication No. 47-42798 discloses a device in which a cushioning soft material is provided on the outer peripheral edge of a bowl-shaped main body. The cushioning soft material is a brush-shaped member, sponge,
It is composed of a cushioning material such as sponge. That is, the cushioning flexible material is essentially breathable. Therefore, the dirt separated and removed from the cotton wool by the cushioning soft material flows into the depressurization area through the cushioning soft material, so that the dirt can be collected in the depressurization area.
しかしながらこの装置は、次のような別の解決すべき
課題を有している。However, this device has another problem to be solved as follows.
（１）仕切壁である椀状の本体とは別に緩衝性柔軟材を

が、これは相当困難である。(2) Since the cushioning soft material is essentially breathable, it has a predetermined vacuum in the depressurized area (sufficient vacuum for vacuum adsorption on the wall surface and sufficient for collecting dirt in the depressurized area). In order to generate, the decompression generation means (exhaust means) having a considerably high capacity is required. For this reason, the device becomes large and the manufacturing cost becomes high. In order to solve this problem, it is necessary to properly design the breathability of the cushioning soft material, which is considerably difficult.

は一辺が1mmの正方形となっている。In the device according to the present invention, as shown in FIGS. 3 and 4, it is important that the contact portion 48a of the partition wall 36 is provided with the groove 68 for communicating the inside and outside of the decompression region 50. In a specific example, FIG. 4 (FIG. 4 shows the partition wall 36 viewed from the inner surface side) is provided on the inner surface (left surface in FIGS. 2 and 3) of the contact portion 48a of the partition wall 36. As shown in FIG. 5, a plurality of grooves 68 are provided at intervals in the circumferential direction, and each groove 68 extends radially outward in the radial direction. The vertical cross-sectional shape of each groove 68 may be an appropriate shape, but is substantially rectangular in the illustrated specific example. The number and cross-sectional area of the grooves 68 can be set as appropriate, but as will be easily understood from the description below, when the number is increased or the cross-sectional area is increased, the grooves 68 pass through the grooves 68 and enter the decompression region 50. The amount of fluid flowing in is high, and therefore
A relatively large and high-performance depressurization generating means is required to depressurize the depressurization region 50 as required, and on the other hand, when the number is reduced or the cross-sectional area is reduced, the fluid flow through the groove 68 is reduced. Therefore, the ability to collect the dirt removed in the processing operations described below is reduced.
From the above, in the specific example, the contact portions 48a having a diameter of about 230 mm of the partition wall 36, at substantially equal intervals in the circumferential direction.
72 grooves 68 are formed, and the cross-sectional shape of the groove 68 is a square having a side of 1 mm.

The fluid within 50 (eg, air for use in the atmosphere, or water for use in water, for example) is exhausted through tube 66, which depressurizes the decompression region 50 as desired. It Thus, as can be easily understood from FIG. 2, the partition wall 36 is made of a relatively soft material, and the contact portion 48a is made to come into contact with the pressure receiving body 2 by a relatively small force.
With respect to the wall surface W and the direction away from the wall surface W, the surrounding fluid pressure acting on the pressure receiving body 2 due to the fluid pressure difference between the inside and outside of the depressurization region 50 is substantially from the pressure receiving body 2 to the support frame 16 and. 18 and wheels 22a, 22b, 30a and 3
It is transmitted to the wall surface W via 0b, so that 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 depressurized region 50 is
The partition wall 36 is biased toward the wall surface W and its contact portion 48a is formed.
To contact the wall surface W. Therefore, the contact part 48a of the partition wall 36 is brought into contact with the wall surface W by this, and the wall surface processing work described later, that is, the cleaning work in a specific example, can be performed by the contact pressure between the contact part 48a and the wall surface W. . Further, in this way, since the seal member 60 is formed of a relatively flexible material, the surrounding fluid pressure acting on the seal member 60 due to the fluid pressure difference between the inside and outside of the depressurization region 50 causes the seal member 60 to rotate. It is biased toward the body 44, so that the other end of the seal member 60 is brought into contact with the rotating body 44. Accordingly, a substantially upstream dense seal is maintained between the pressure receiving body 2 and the rotating body 44, and external fluid flows into the decompression region 50 through between the rotating body 44 and the sealing member 60. Is prevented.

離された後のきれいな流体が外部に排出される。When the electric motor 40 is energized in such a suction state, the partition wall 36 is also integrated with the rotating body 44 by the arrow 58 (FIG. 1).
Is rotated in the direction indicated by. In this way, the cleaning work of the wall surface W is performed by the rotation of the partition wall 36. That is, in the adsorption state, the contact portion 48a of the partition wall 36 is brought into contact with the wall surface W at a required pressure, and therefore,
When the partition wall 36 is rotated by the urging of the electric motor 40, the contact portion 48a thereof moves while being used on the wall surface W, and the cleaning of the wall surface W is transferred by the action of the contact portion 48a. In the adsorption state, the decompression region 50 is decompressed as required, while the contact portion 48a of the partition wall 36 is formed with a plurality of grooves 60 at intervals in the circumferential direction,
Therefore, as shown by the solid line in FIG. 3, the flow of the fluid from the outside through the groove 60 and into the decompression region 50 is substantially constantly generated. Therefore, the contact portion of the partition wall 36 outside the decompression region 50
Dirt generated in the vicinity of 48a (deteriorated coating, rust, water stain, etc.) is carried by the above-described fluid flow through the groove 68 into the decompression region 50, and thus the dirt generated during cleaning is scattered around. Is reliably prevented.
In the specific example, since the grooves 68 extend radially, a radial flow that is directed radially inward is generated over substantially the entire circumference of the partition wall 36, which may cause dirt to be scattered around the entire circumference of the partition wall 36. To be prevented. The dirt transferred into the decompression region 50 is conveyed to the separator (not shown) through the tube 66 together with the fluid in the decompression region 50 by the action of the decompression generation means 64, and as required in this separator. The separated and separated clean fluid is discharged to the outside.

ができる。In the specific example, a groove 68 is formed on the inner surface of the contact portion 48a of the partition wall 36.
In addition, the following advantages are associated with the formation of the. That is, the contact portion 48 is caused by the existence of the groove 68.
The portion of the groove a where the groove 68 does not exist protrudes toward the wall surface W, and the portion substantially acts on the wall surface W. Therefore, the cleaning efficiency at the time of cleaning can be improved.

着力を得ることができる。Further, in the specific example described above, the contact portion of the partition wall 36.
Since 48a can be displaced with respect to the pressure receiving main body 2 in the direction of the wall surface W and in the direction away from it by a relatively small force, the surrounding fluid pressure acting on the partition wall 36 causes the contact portion 48a of the partition wall 36 to move. It is brought into contact with the wall surface W.
Therefore, the contact pressure between the contact portion 48a and the wall surface W, in other words, the working pressure of the cleaning operation is substantially constant, whereby substantially uniform cleaning of the wall surface is achieved. Further, since the contact pressure between the contact portion 48a of the partition wall 36 and the wall surface W is affected by the surrounding fluid pressure acting on the partition wall 36, the contact pressure can be easily changed by changing the pressure receiving area of the partition wall 36. Further, in connection with this, by appropriately setting the pressure receiving area of the pressure receiving main body 2, it is possible to obtain a desired suction force required to suck the device on the wall surface W.

向に向けられる。As will be easily understood, when the electric motors 24 and 32 are operated and the wheels 22a and 22b and the wheels 30a and 30b are rotationally driven in the same direction, the device goes straight along the wall surface W and the wheels 22a and 22b. When the wheels 30a and 30b are rotationally driven in opposite directions, the device is rotationally moved around its central axis and is oriented in a desired direction.

に多目的に使用することができる。Although one specific example of the apparatus configured according to the present invention has been described above, the present invention is not limited to the specific example, and is disclosed in, for example, JP-A-60-25669 and JP-A-56-521.
It can be applied to devices capable of adsorbing to various wall surfaces disclosed in Japanese Patent Laid-Open No. 80-80, Japanese Patent Laid-Open No. 53-126765 and the like. That is, for example, as disclosed in JP-A-60-25669, one end of the partition wall is connected to a pressure receiving main body, and the pressure receiving main body is drive-connected to a drive source such as an electric motor mounted in the apparatus main body. It can be similarly applied to a device in which the partition wall is rotated integrally with the pressure receiving body. This type of apparatus can also clean the wall surface by rotating the partition wall. Further, for example, Japanese Patent Laid-Open No. 56-
As disclosed in Japanese Unexamined Patent Publication No. 52180 and Japanese Unexamined Patent Publication No. 53-126765, one end of a partition wall is connected to a pressure receiving main body, and the pressure receiving main body has a dedicated surface treatment such as a polishing / cleaning material projection means. It can also be applied to an apparatus in which the means is provided and the surface treatment means treats the wall surface in the decompression region as required. In this type of device, the partition wall does not rotate,
Therefore, it does not have a function of treating the wall surface, and the treatment of the wall surface is performed by a dedicated surface treatment means. Further, for example, as disclosed in a part of JP-A-53-126765, one end portion of the partition wall is connected to the pressure receiving main body,
A device in which the decompression area is defined by the partition wall and the wall surface (or the decompression space is defined by the partition wall and the wall surface by covering the inner surface of the pressure receiving body with the partition wall), and the device moves along the wall surface by the action of the traveling means. Can also be applied to. In the apparatus of this form, by separately mounting, for example, surface treatment means, it can be used for various purposes such as treatment of wall surfaces.
＜発明の効果＞ 本発明によれば次のような効果が達成される。<Effects of the Invention> According to the present invention, the following effects are achieved.

ので、製造コストを大幅に低減することができる。(1) The contact portion that comes into contact with the wall surface of the partition wall is provided with a groove that communicates between the inside and outside of the decompression region, and the groove is radially spaced around the contact portion and substantially all around the circumferential direction. A plurality is provided. That is, since the groove is formed integrally with the partition wall, the number of parts is reduced and there is no need to assemble as compared with the conventional device in which a cushioning soft material is separately provided, so that the manufacturing cost is significantly reduced. be able to.

できる。(2) Since it is extremely easy to properly set the number and cross-sectional area of the grooves, it is easy to appropriately design the ability to vacuum-adsorb on the wall surface and the ability to collect dirt removed from the wall surface. is there. Therefore, as compared with the conventional device in which the cushioning soft material is separately provided, the reduced pressure generating means can be remarkably downsized, and the cost can be reduced also in this respect.
（３）前記効果（１）及び（２）により、装置全体の構

低減される。(3) Due to the above effects (1) and (2), the configuration of the entire apparatus is significantly simplified, and the manufacturing cost of the entire apparatus is significantly reduced.

のクリーニング等の表面処理が効果的に遂行される。(4) Due to the groove provided in the above-described form at the contact portion that comes into contact with the wall surface of the partition wall, the portion where the groove does not exist protrudes toward the wall surface. A plurality of portions projecting toward the wall surface are provided radially at intervals in the circumferential direction of the contact portion and over substantially the entire circumference in the circumferential direction. As a result, when the partition wall is rotated by the drive source, the side portion of the protruding portion facing the rotation direction moves in a direction substantially orthogonal thereto, thereby effectively removing the adhered matter on the wall surface. The surface treatment such as cleaning of the wall surface is effectively performed.

とが確実に防止される。At the same time, a radial flow radially inward is generated over substantially the entire circumference of the partition wall, and the fluid outside the decompression region flows into the decompression region through the groove. This fluid flow is
The dirt is constantly generated during the rotation of the partition wall, so that the dirt generated by using the device is collected in the depressurized area by the flow of the fluid, thus reliably preventing the dirt from scattering around.

Therefore, unlike the conventional device, the surface treatment member such as the cushioning soft material is not separately provided at the contact portion of the partition wall, and the surface treatment can be effectively performed only by the partition wall, and the dirt can be collected further. Definitely carried out.

が長くなる。(5) The partition wall has a main portion that extends outward from one end toward a contact portion that contacts the wall surface, and a main portion that extends outwardly from the contact portion toward the other end, and away from the wall surface. Since the partition wall has an extended extension and is formed in a circular shape together with the contact portion, the contact portion of the partition wall can be displaced with respect to the pressure receiving main body in the direction of the wall surface and in the direction away from the wall surface. The contact portion is brought into contact with the wall surface by the surrounding fluid pressure acting on. Therefore, the contact pressure between the contact portion and the wall surface, that is, the working pressure of the surface treatment operation such as cleaning is substantially uniform, and the substantially uniform surface treatment operation of the wall surface is achieved. Therefore, uneven wear of the contact portion (also the surface treatment portion) in which the groove is formed is prevented, a predetermined suction force is maintained, and the life of the surface treatment portion is extended.
