The above-mentioned device includes a pressure receiving body, a seal attached to an opening of the pressure receiving body and defining a reduced pressure area in cooperation with the pressure receiving body and a wall surface, and a reduced pressure source that generates a vacuum in the reduced pressure area.
The cleaning chamber is provided with a housing for defining a cleaning chamber and an abrasive material projection means for projecting an abrasive material into the cleaning chamber, and the cleaning chamber is connected to the depressurized area via a vacuum breaker. In such devices, when the fluid pressure in the reduced pressure area decreases, the fluid in the grinding chamber flows into the reduced pressure area through the vacuum breaker, thereby passing from the cleaning chamber through the vacuum breaker to the reduced pressure area. A fluid flow occurs. When such a fluid flow occurs, the abrasive material projected from the abrasive material projection means toward the wall surface and the dust generated during cleaning are carried by this fluid flow to the depressurized area, and the pressure is further reduced. By the action of the source, it is conveyed to a recovery device and collected by this recovery device. In this way, it is possible to easily perform the cleaning work on the wall surface, and it is also possible to prevent ocean pollution or air pollution caused by the abrasive material and the dust generated during cleaning.

It also has As shown in FIG. 1, the pressure regulator 4 is of a known type, and includes a valve 41 and a spring 42 that elastically biases the valve 41 in the closing direction. When the pressure falls below a predetermined level, the valve 41 opens against the force of the spring 42. This pressure regulator 4 is attached to the pressure receiving main body 1. In addition, the partial pressure collector 13
has a supply port 131 and a fluid discharge port 132 formed in its upper part, and a separated material discharge port 133 formed in its lower part. This separation collector 13 is arranged at the back of the pressure receiving body 1, and its supply port 131

Therefore, in the specific example, as will be described later, the fluid that has flowed into the separation collector 13 from the supply port 131 is converted into seawater in the separation collector 13, as will be easily understood. The separated liquid is discharged through the fluid outlet 132 and sent to the reduced pressure area 3 through the tube 15 and the pressure regulator 4, while the separated liquid is separated into waste generated during the cleaning operation. The waste material separated is discharged through the separated material outlet 133 and transferred into the pipe 5 by the action of the rotary feeder 16. Incidentally, the separation collector 13 and the rotary feeder 16 are known per se.

ることができる。 When the pump 8 is activated, a fluid such as seawater present in the reduced pressure area 3 is discharged through the pipe 5 and the flexible tube 6 to the outside, in the specific example to the sea, and a vacuum is created in the reduced pressure area 3. At this time,
It is important to set the suction capacity (i.e. suction amount) of the pump 8 to be larger than the amount of fluid such as seawater flowing into the depressurized area 3 from the gap between the wall surface O and the seal 2. As a result, a desired vacuum can be generated within the reduced pressure region 3.
In this way, the pressure receiving body 1 is attracted to the wall surface O due to the fluid pressure difference between the inside 3 of the reduced pressure area and the outside of the reduced pressure area 3, that is, the outside. In the specific example, the seal 2 cooperates with the pressure-receiving body 1 and the wall O to define a substantially high-density depressurized region 3, so that the pressure-receiving body 1 is adsorbed to the wall O by a relatively low-capacity decompression source. be able to.

排出され、海水の汚染が防止される。 When the fluid pressure in the pressure reduction area 3 becomes lower than a predetermined level, the difference in fluid pressure between the upstream side and the downstream side of the pressure regulator 4 (in other words, the fluid pressure in the hood 12 of the cleaning unit and the fluid pressure in the pressure reduction area 3) is detected. pressure difference)
Due to this, the valve 41 is opened against the elastic biasing force of the spring 42, and the separation collector 4 and the reduced pressure region 3 are brought into communication via the pressure regulator 4. Thus,
As will be readily understood, the action of the pump 8 draws in fluid such as seawater within the hood 12, creating a flow of fluid such as seawater from within the hood 12 through the reduced pressure region 3 to the reduced pressure source 8. . That is, as shown in FIG. 1, fluid such as seawater flows into the hood 12 from the outside through the gap existing between the open end of the hood 12 and the wall surface O, and this fluid first passes through the flexible tube 14. It flows into the separation collector 13. At this time, the rotating brush 10 is performing cleaning work by acting on the surface of the wall O, and therefore wastes generated during the cleaning work (such as scraps removed from the surface of the wall O by the action of the rotating brush 10,
Rust, etc.) is carried by this fluid flow to the separation collector 1.
Carried within 3. In the separation collector 13, since the flow of the fluid described above decreases, waste (such as scraps, rust, etc.) falls downward due to its own weight, and thus the waste present in the fluid such as seawater is removed. are separated. The waste-separated fluid is discharged through fluid outlet 132 and further into tube 15.
and flows into the reduced pressure area 3 through the pressure regulator 4.
The fluid that has flowed into the reduced pressure region 3 further
It flows through the pipe 5 and flexible tube 6 to the pump 8 (ie, flows as shown by the solid arrow in FIG. 1). On the other hand, the waste separated in the separation collector 13 (such as scraps, rust, etc.) is discharged through the separated material discharge port 133 as shown by the broken line arrow in FIG. Therefore, it is transferred into the pipe 5. At this time, in the pipe 5, fluid is flowing from the depressurized region 3 toward the pump 8, as shown by the solid line arrow, and therefore, the separated material, that is, the waste, transferred into the pipe 5 as described above is flowing. is carried toward the pump 8 along with this flow. The thus transported waste is collected in a collection container 7 placed in front of the pump 8, that is, on the upstream side.
The fluid, such as clean seawater, from which waste has been removed is discharged to the outside, such as the sea, by the action of the pump 8, thereby preventing contamination of the seawater.

る。 Note that if the surface of the wall O has many irregularities and the gap between the wall O and the seal 2 becomes large, a large amount of external fluid such as seawater will flow into the depressurized area 3 through the gap. As a result, the fluid pressure within the reduced pressure region 3 increases. As a result, the valve 41 of the pressure regulator 4 is displaced in the closing direction by the elastic biasing force of the spring 42, and the pressure-reduced area 3
The amount of fluid flowing into the rotary brush 10 is reduced, resulting in a reduced ability to suction transport the waste removed by the rotating brush 10. Therefore, if there are many irregularities on the surface of the wall O, it is desirable to set the capacity of the pump 8, that is, the suction amount, large in advance. It is possible to prevent a decline in performance.

In addition, since the waste generated during cleaning work is sucked and collected by the action of the pump 8 that creates a vacuum in the depressurized area 3, there is no need to provide a separate device for collecting waste. , the structure of the device can be simplified and the device itself can be made smaller. Further, when the fluid pressure in the reduced pressure region 3 becomes lower than a predetermined value, the pressure regulator 4 opens and fluid flows into the reduced pressure region 3, so that an abnormal drop in the fluid pressure in the reduced pressure region 3 can be prevented. Furthermore, the separation collector 1 is removed from inside the hood 12.
Fluid containing waste (such as scraps, rust, etc.) that has flowed into the chamber 3 is separated into fluid such as seawater and waste in the separation collector 13, and only the fluid passes through the pressure regulator 4 and is returned to the reduced pressure area 3. The waste flows from the vacuum area 3 via the rotary feeder 16 to the pump 8.
Since the pressure regulator 4 is configured to be supplied with fluid flowing toward the pressure regulator 4, only fluid such as seawater flows through the pressure regulator 4, and troubles caused by waste generated in the pressure regulator 4 can be solved.
