DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is a coating adhering to the ship outside plate
The present invention relates to a scraping and cleaning apparatus suitable for scraping a film skeleton layer .

[0002]

2. Description of the Related Art Conventionally, when cleaning the exterior surface of a large vessel or the like, a large amount of a linear cleaning solution sprayed from a high-pressure injection nozzle is sprayed on the cleaning surface to remove dust and various organisms attached to the exterior surface. (For example, barnacles, glue, slime, etc.).

[0003] In recent years, antifouling paints have been used for painting the outer surface of ships in order to prevent the adhesion of such debris and the like. It has an antifouling effect by dissolving inside. For this reason, the coating layer on the outer surface of the ship, especially in the seawater submerged portion, becomes a residual coating portion in which the antifouling agent component has been dissolved, and a generally sponge-like fragile porous layer having a thickness of about 20 to 100 μm is formed. Have been.

[0004] Furthermore, dissolved substances in seawater mainly consisting of salt and the like also adhere to the outer surface of the ship. However, when the outer surface of the ship is washed, particularly when the ship is repaired, the outer surface of the outer surface before repainting (surface). In the cleaning step of the treatment, it is necessary to remove these dusts and deposits on the surface and unnecessary layers of the old coating (such as the porous layer).

[0005]

However, in the conventional cleaning method using a high-pressure nozzle, dust and the like are removed only with linear spray water. Although it is effective for the effective removal of extraneous matter, there is a problem that it is not possible to uniformly and reliably clean the entire surface of the surface. Complementary work was needed.

On the other hand, the unnecessary layer on the outer surface, particularly the part where the antifouling agent has disappeared and became void (formation of skeleton) is a sponge-like porous layer. There are the following problems at the time.

First, since unnecessary layers are physically fragile,
If repainting is performed on top of that, the adhesion of the repainted film decreases.
Also, since seawater salts and slime remain in the skeleton, the interlayer adhesion of the repainted film is hindered by the influence of these salts and the like. Further, due to the influence of air or the like remaining in the porous material, foaming is generated in the coating film applied on the upper portion, so that the coated surface is roughened.

Problems caused by these unnecessary layers can be prevented by completely cleaning the exterior surface, that is, by completely removing dust and unnecessary layers. Difficult and costly. Also,
It is inefficient to perform the manual cleaning of a large ship or the like, and it is still difficult to provide a realistic solution in view of rising labor costs and worker safety.

[0009] Further, if the jetting pressure of the defective cleaning part is further increased or the removal work is individually performed manually, not only the unnecessary layer of the antifouling paint part but also the undercoating part will be cut off. At the time of repainting, there is a problem that not only the antifouling paint but also the undercoating has to be started again, and since these are partial, a new problem that coating unevenness occurs when viewed as a whole has also arisen.

Further, in the conventional cleaning method using high-pressure cleaning water, a large amount of cleaning water is sprayed on the cleaning surface and the cleaning water is washed off by dropping the cleaning water. There is also a problem that causes marine pollution because it is discarded in the sea without being able to complete.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a scraping and cleaning apparatus excellent in cleaning characteristics suitable for cleaning a large flat or curved surface of a ship or the like.

Furthermore, it is also possible to provide a scraping and cleaning apparatus or method capable of efficiently and reliably removing not only unnecessary matters such as dust attached to the outer surface of a ship or the like, but also a deteriorated surface layer coating film or the like.

[0016]

The invention according to the present application is configured as described above, and has the following operation. First, in the first aspect of the present invention, since the cleaning brush is driven to be in sliding contact with the cleaning surface, the cleaning brush removes unnecessary substances such as the surface layer of the cleaning surface and dust attached thereto. Within the contact width, it is scraped off by contact with the cleaning brush.

[0017] When the cleaning brush is used to inject the cleaning liquid onto the cleaning surface of the cleaning portion with a high pressure, the debris and the like shaved off by the brush are washed away, and unnecessary objects such as barnacles stuck to the surface cannot be completely removed by the brush itself. The removal operation using high-pressure jet water is repeated.

That is, by providing the cleaning liquid to the cleaning surface of the cleaning portion by the cleaning brush, the cleaning by the brush is complemented, and the fine remaining surface coating portion (such as a porous unnecessary layer) which cannot be removed by the brush itself is removed. In addition to being completely removed by the cleaning liquid ejected from the nozzle at a high pressure, it also has the function of washing away debris and the like scraped off with a brush.

Further, the cleaning brush and the nozzle are integrally formed.
Moving means for moving the provided supporting means three-dimensionally along the cleaning surface, so that the
Since the sliding portion of the cleaning brush moves with respect to the cleaning surface, a wide cleaning area can be secured and continuous cleaning can be performed. In addition, in the present invention, the supporting means is provided with the cleaning means.
Equipped with angle adjustment means to change the angle freely along the surface
So that the cleaning part can be tilted along the cleaning surface.
Cleaning can be performed efficiently and with high workability.

Here, the cleaning brush of the present invention may have a configuration in which the portion that comes into contact with the cleaning surface is a brush-like member, and the surface is slidably contacted with the surface layer in this contact area. Then, it can be applied to the present invention. By providing such a planar contact (sliding contact) portion, unnecessary substances in the washing area can be completely and uniformly removed, and particularly, remains on the surface layer on the outer surface of the ship. Unnecessary coating film such as skeleton can be completely removed.

In the invention described in claim 1 of the present application ,
There is provided support means for integrally supporting the cleaning brush and the nozzle. This is because, when guiding the high-pressure jet water from the nozzle to the cleaning portion of the cleaning brush, if these are made as separate members, the structure of the support member and the combination with the brush sliding mechanism and the like are prevented from becoming complicated. That's why.

By providing a support member for integrally supporting the cleaning brush and the nozzle as in the present invention, the driving mechanism for the cleaning brush and the nozzle can be shared, and the arrangement and configuration thereof are simplified, so that the design is simplified. In addition, the maintenance of the apparatus becomes easy.

The arrangement of the cleaning brush and the nozzle with respect to the support member may be such that the high-pressure jet water from the nozzle is guided to the cleaning surface (the cleaning portion) in contact with the cleaning brush. The high-pressure jet water may be guided directly to a portion where the brush contacts the cleaning surface, or may be guided to a portion to be cleaned or a portion after cleaning.

By providing such an integral support member, the shaving by the cleaning brush and the rinsing by the high-pressure jet water can be continuously and reliably performed, so that the cleaning operation for the cleaning portion can be efficiently performed. Often done.

Next, in the invention of claim 2, wherein the mobile
While the support means is being moved by the means,
Since the driving means for reciprocating or rotating the supporting means while sliding on the cleaning surface is provided, the cleaning brush (and nozzle) slides on the cleaning surface while reciprocating or rotating. Therefore, the cleaning brush is applied to the same portion a plurality of times with reciprocating or rotating movement to scrape off dirt and unnecessary paint film on the surface layer portion, and the high pressure jet water is also sprayed on the cleaning surface a plurality of times. .

By performing this cleaning operation in conjunction with the moving speed of the moving means, it is possible to continuously and reliably perform the removal operation over the entirety of the cleaning site. The cleaning area can be secured.

The means for supporting the cleaning brush and the nozzle used here may be any as long as they integrally support them in accordance with the type of driving means for the sliding operation. For example, as long as the cleaning brush comes into sliding contact with the cleaning surface by rotational movement, a cleaning brush and a nozzle provided on a disk-shaped maintaining means may be used. By providing the cleaning brush and the nozzle at positions radially from the center of rotation, the brush can be continuously scraped off and the high-pressure jet water can be used for washing. Further, for example, in the case of a reciprocating motion, if the cleaning nozzle and the brush are arranged along the direction of the sliding movement, the cleaning surface can be continuously cleaned by these.

According to the fourth aspect of the present invention, the cleaning liquid is injected at a high pressure onto the sliding orbit of the cleaning brush at the contact position of the cleaning brush or at the position before and after sliding, alternately and continuously with the cleaning by the cleaning brush. While the cleaning brush slides on the cleaning surface, the support means is moved along the cleaning surface at three-dimensionally freely changing angles.

In this cleaning method, the cleaning with a cleaning brush and the so-called jet cleaning with a high-pressure injection cleaning liquid are performed at the same time, and a more accurate cleaning is performed by a synergistic effect of both of these cleanings.

According to the present invention, the brush cleaning and the jet cleaning are not performed separately, but the part of the cleaning part of the cleaning brush which the brush directly contacts, the part which comes into sliding contact therewith, or the part after sliding. By performing high-pressure injection of a cleaning liquid onto a portion (or a plurality of these portions) to continuously perform brush cleaning and jet cleaning, the cleaning effect is significantly improved as compared with individual cleaning. .

As the apparatus for performing such continuous cleaning, the apparatus according to the present invention described above is suitable. However, the present invention is not limited thereto. For example, a brush cleaning apparatus and a jet cleaning apparatus are arranged in the same cleaning area. The method according to the present invention can also be carried out by a method for cleaning the material.

[0032]

Hereinafter, the present invention will be described in more detail by way of examples. FIGS. 1 to 3 show a schematic configuration of a cleaning apparatus according to an embodiment of the present invention. FIG. 1 is an enlarged view of a cleaning brush, nozzle support means and driving means thereof, and FIG. FIG. 3 shows the arrangement of brushes and nozzles provided on the support means.

In this embodiment, the brush 1 and the nozzle 2 are disposed on a disk-shaped support member 4, and the drive unit 5 rotates the support member 4 together. Furthermore,
The cleaning surface 10 is pressed by the pressure of the air cylinder 11.
, The tip of the brush 1 moves while sliding on the cleaning surface 10 in accordance with the operation of the drive unit 5.

The brush 1 is formed by bundling wires of an appropriate length, and is fixed to the support member cleaning surface 10 in a state of being bound by the holding member 21. The tip of the cleaning brush 1 only needs to have a brush-like member in contact with the cleaning surface 10, and has a configuration in which the surface of the cleaning brush 1 comes into sliding contact with the surface layer in this contact area. Is preferred.

For this reason, in the present embodiment, wires having the same length are used so that the tip of the brush 1 has a substantially planar shape, and the driving method of the support member 4 is a rotary motion. 4 has a brush 1 suspended therefrom.

However, the embodiment of the present invention is not limited to this type, and any other type of brush may be used as long as the cleaning part is made planar by sliding movement of the tip of the brush. However, the present invention can be applied even if a predetermined angle is provided to the support means.

The material of the cleaning brush 1 is preferably a flexible member made of resin such as nylon, and for cleaning the outer surface of the hull, a harder material than a relatively soft one has a better cleaning effect. Get higher. The configuration of the brush itself is
It is preferable to appropriately select the wire diameter and length of the single body, the diameter and material of the assembly brush, and the like.

In the case of nylon, the brush diameter is φ
Although 0.3 to 3 mm can be used, φ0.5 to 2 mm is preferable in consideration of strength and detergency. The diameter of the assembly brush may be about 30 to 200 mm in the case of a circular shape.
It is preferably about 0 to 100 mm. Brush length is 30
A thickness of about 200 mm is conceivable, but a strength of about 50 to 150 mm is preferable in consideration of strength, wear, and the like.

Since the present embodiment was developed as a cleaning device for the outer surface of a ship, if a metal wire is used for the cleaning brush, the undercoating portion or the outer surface itself may be shaved. Therefore, it is not preferable, but an appropriate material such as a steel product may be selected depending on an object to be cleaned (for example, a barn).

[0040] At this time, when considering only the surface treatment step before repainting is preferably only unnecessary portions of the old paint can be accurately removed. For example, in consideration of removing only the skeleton described above, a relatively soft brush member is selected, the pressing pressure on the cleaning surface is set to a relatively low value, and the cleaning is performed together with the high-pressure water cleaning. Only the old painted part can be accurately removed over the entire surface of the cleaning part.

The nozzle 2 is for injecting a predetermined cleaning liquid at a high pressure onto a cleaning portion of the cleaning surface 10 by the brush 1.
As a result, the cleaning part is so-called jet-cleaned. In this embodiment, are arranged so as washing liquid to enhance the cleaning effect of the jet washing is injected perpendicularly to the cleaning surface 10.

In FIG. 1, the nozzle 2 for jetting the cleaning liquid is exemplified by a wide flat nozzle, but a nozzle for jetting in a circular or linear shape may be used depending on the manner of movement of the cleaning brush. However, in consideration of the pressure of the cleaning liquid jet-jetted to the cleaning part and the cleaning part (area), it is preferable to inject the cleaning liquid at a high pressure while moving the cleaning liquid with a wide flat nozzle.

The tip of the spray portion of the nozzle 2 is arranged at a certain distance from the cleaning surface 10. If this distance is short, the cleaning effect is high, but the work area is small because the spray area is small. If the distance is too long, the cleaning effect is reduced.
It is preferable that the distance can be changed in consideration of the material of the cleaning surface, the degree of adhesion of dust, and the like.

In this embodiment, the initial interval is approximately 1
The distance is adjusted to 60 mm. This is based on the length of the brush member (150 mm). When a short brush is used, the initial distance is changed accordingly, and the brush is used due to wear of the brush. Can be changed to

The support means used in this embodiment integrally supports the cleaning brush and the nozzle, and is constituted by a disk-shaped support member 4. FIG. 3 shows the arrangement of the brush 1 and the nozzle 2 in the support member 4. FIG.
2 shows a state in which the support member 4 is viewed from the cleaning surface 10 side in FIG. 1.

On the supporting member 4, six brushes 1 and nozzles 2 are alternately arranged in a line along a circumferential direction near the outer peripheral portion, and further arranged in a line in the circumferential direction closer to the center than the line. Three brushes 1 and three nozzles 2 are alternately arranged.
The arrangement of these brushes and nozzles may be selected as appropriate according to the shape and size of the brush used, or the shape of the nozzle, the jet pressure, the jet direction, and other design conditions.

For example, the arrangement of the cleaning brush and the nozzle with respect to the support means is arranged in two rows in the circumferential direction of the disk-shaped support member in FIG. 3, but is arranged in a single row or three or more rows. A plurality of brushes and nozzles may be arranged in series in the radial direction, or a mixture of these may be used. However, any brushes and nozzles can be arranged at least on the same rotation orbit.

By arranging the cleaning brush in this manner, the cleaning liquid can be continuously and effectively injected to the cleaning portion by the cleaning brush, and the cleaning with the cleaning liquid can be accurately performed before and after the sliding movement of the cleaning brush. Done. As an example of simultaneous operations, an assembly brush may be formed in an annular shape and an injection nozzle may be provided at the center thereof.

Although the brush and the nozzle are supported by the same support member in this embodiment, they may be supported by separate members. In this case, at least the brush supporting member needs a driving means for reciprocating or rotating with respect to the cleaning surface, but the nozzle supporting member covers the sliding contact portion of the brush with the cleaning liquid jetting portion from the nozzle. If it does, the driving means is not necessarily required.

Next, the drive unit 5 in the present embodiment is for rotating the support member 4, whereby the brush 4 supported by the support member 4 slides on the cleaning surface 10. Has become.

In this embodiment, an apparatus using an air-motor / rotary joint as the driving unit 5 is applied. The air-motor / rotary joint is composed of a rotary drive unit and a power transmission unit. The air-motor-rotary joint is driven to rotate by the air motor, and a rotational drive force is transmitted to the support member 4 by the power transmission unit. Is done.

As the driving means for driving the support member 4, a driving means other than the air-motor / rotary joint used in this embodiment may be used. For example, a jet drill, a hydraulic motor Driving means such as motors and electric motors can be applied.

Next, the cleaning apparatus according to the present embodiment uses a modified forklift 6 as the moving means. As shown in FIG. 2, a cleaning unit 30 is provided at the tip of the forklift 6, and the cleaning unit 30
Is configured to be movable in the up-down direction and the forklift 6 itself is also movable in the front-rear direction and the left-right direction. It has become.

[0054] Further, in this embodiment, for example, even if the cleaning surface as shown in Figure 2 are slopes, without angle adjusting means (not capable of cant and along the cleaning site by the brush 1 and the nozzle 2 to the cleaning surface ), The angle can be changed by about 50 degrees in the upper part and about 10 degrees in the lower part in the elevation direction, and the angle can be changed by about 10 degrees to the left and right in the horizontal direction.

[0055] Incidentally, not but by applying a commercial truck as a moving means to reduce the manufacturing cost is not limited thereto in the present embodiment, the moving means suitable for utilization, along a cleaning surface For example, as long as the cleaning unit can be moved, a moving means such as a construction machine such as a small excavator or an angle adjusting mechanism may be applied, or a dedicated moving means may be constructed.

That is, in the present embodiment, in addition to the moving means for moving the cleaning portion along the cleaning surface, adjustment means such as angle adjustment with respect to the cleaning surface are further provided. These can be combined with the cleaning device. It has the advantage that washing can be performed efficiently and with high work efficiency. If the moving means and the adjusting means are efficiently arranged, the moving part and the adjusting part of the forklift can be applied as in this embodiment. The moving means and the adjusting means having a unique configuration may be constructed.

When the cleaning surface 10 draws a gentle curve, it is difficult to accurately trace the curved portion (curved surface), and forcing it to reduce workability.

The cleaning apparatus according to this embodiment includes an air cylinder 11 that slides a fixed distance (about 50 mm in this embodiment) and a stopper 12. That is, in order to enhance the cleaning effect of the brush 1, the air cylinder 1
The support member 4 is pressed against the cleaning surface 10 by the pressing pressure of 1.

For this reason, even if the cleaning surface 10 is constituted by a large curved surface, and the relative distance between the cleaning device and the cleaning surface fluctuates with the movement of the cleaning part, the sliding of the air cylinder 11 and the appropriate pressing pressure make it possible. This ensures that the brush is securely in contact with the cleaning surface.

In this embodiment, as shown in the figure, the air cylinder 11 is connected to the cleaning section 3 at the tip end of the forklift 6.
Although it is attached between the drive unit 5 and the drive unit 5, it is not limited to this method as long as it can press the cleaning brush against the cleaning surface with a predetermined pressure. The air cylinder 11 of this embodiment may have a stroke of 50 mm or more in order to be able to cope with various types of cleaning surfaces.
mm is preferable.

The stopper 12 is provided to maintain the relative distance between the support member 4 and the cleaning surface 10 and to adjust the pressure applied by the air cylinder 11. However, a pressure sensing means and a relative interval detecting means are provided at the mounting portion.

That is, the drive unit 5 is driven by the air cylinder 11.
While the cleaning brush (and nozzle) is pressed against the cleaning surface 10 via the support member 4, the pressing pressure is kept constant by the action of the stopper 12, and the distance between the nozzle and the cleaning surface is kept constant. The cleaning brush can always contact the cleaning surface.

For example, when the cleaning unit 30 is moved upward when the cleaning surface 10 is bent as shown in FIG. 2, the pressing force of the stopper 12 is increased by the pressure-sensitive means (or the supporting means). The relative distance between the air cylinder 11 and the cleaning surface is shortened.) The force (or the amount of movement) of the air cylinder 11 to push back to the right is adjusted by the air cylinder 11 so that the air cylinder 11 does not receive excessive pressing pressure. The operation is controlled.

Such stopper means are not limited to those shown in the present embodiment, but may be those which detect only the pressure, those which detect only the relative distance, or those which detect only the minimum relative distance. It goes without saying that the present invention can be applied to the present invention even if a mechanically detected device is used.

It is preferable to determine an appropriate pressing pressure based on the length, diameter, material, and the like of the brush. However, in consideration of the fact that the brush is shaved during use and shortened, the relative distance between the support member and the cleaning surface is considered. Alternatively, it is preferable to provide a changing means for appropriately changing the pressing pressure, or a control means for controlling these based on experimental data obtained in advance.

Next, Table 1 shows the results obtained when the cleaning apparatus according to the present embodiment was tested in a cleaning operation on the outer surface of the hull. Table 1
The washing condition of the sample was checked visually with the washing surface, and the remaining salt was measured with a surface salinometer (Toa Denpa Kogyo KK SS
M-11P).

[0067]

[Table 1]

In this embodiment, a high-pressure water pump having a pressure of 200 kgf / cm ² and a flow rate of 60 l / min was used for jetting the cleaning liquid. However, if the number of nozzles for jetting the cleaning liquid increases, the flow rate increases accordingly. Pressure is 300Kgf / cm
^2. If it is a high-pressure water pump with a flow rate of about 120 l / min,
It seems that more washing conditions can be supported. These specifications may be determined as appropriate according to the arrangement and the number of nozzles to be used.

As is clear from Table 1, the cleaning apparatus according to the embodiment of the present invention can clean the outer surface of the hull extremely well, and can remove foreign substances such as dusts. It can be seen that the unnecessary layer portion (hydration layer, etc.) of the old coating is also uniformly and reliably removed.

Further, in the above comparative example, a cleaning test was performed with the same amount of water for comparison, but according to the cleaning apparatus according to the embodiment of the present invention, the conventional cleaning method using only high-pressure water was directly performed. As compared with the case, there is an advantage that the amount of washing water can be significantly reduced.

Next, as a second embodiment of the present invention, a reciprocating means for driving the support means will be described. FIG. 4 shows a schematic configuration of the support means and the brushes and nozzles disposed thereon in the second embodiment. In this example,
A rectangular support member 404 is used, and a driving means (not shown) for reciprocating the support member 404 in the direction of the arrow in the figure is provided.

The support member 404 is provided with brushes 401 in a line in the center in the horizontal direction, and the nozzles 402 are arranged in the horizontal direction near the upper and lower edges. Then, the brush 4 moves with the reciprocating movement in the vertical direction by the driving means.
01 moves while sliding on the cleaning surface, and the cleaning portion is washed away by the cleaning liquid ejected from the nozzle 402.

In this embodiment, a nylon brush having a length of 60 mm is used, and the distance between the nozzle and the nozzle is adjusted to 70 mm. According to this embodiment also, the outer surface of the hull could be reliably and uniformly cleaned. In this case, if the nozzle 402 is attached while being inclined in the direction of the brush 401, the cleaning effect is improved.

The arrangement of the brushes and the nozzles shown in these embodiments is not limited to this method, and the brushes and the nozzles are arranged in reverse, those arranged in plural rows, and those arranged alternately. Application examples such as things are conceivable.

As described above, the embodiment according to the present invention comprises a cleaning brush driven so as to be in sliding contact with the cleaning surface, and a nozzle for injecting the cleaning liquid at a high pressure onto the cleaning surface of the cleaning portion by the cleaning brush. A cleaning device comprising: a moving unit configured to move the cleaning brush and the nozzle along a cleaning surface; and a support unit configured to integrally support the cleaning brush and the nozzle; And a drive unit for reciprocating or rotating the support unit for sliding contact of the cleaning brush.

Further, in the first embodiment, the moving means can freely move up and down and left and right along the cleaning surface, and the inclination (elevation angle and horizontal movement) of the cleaning part (movement locus of the brush tip) by the cleaning brush. (Angle) is also provided.

Further, there are provided means for adjusting or controlling the relative distance between the support member and the cleaning surface, brush pressing means for pressing the cleaning brush against the cleaning surface with a predetermined pressure, and means for adjusting the pressure.

Further, there are provided a relative positional relationship measuring means for measuring a relative distance (relative positional relationship) between the cleaning surface and the cleaning device, and a control device for adjusting a moving state of the device based on the measurement result. It is preferable to operate the moving means based on the control signal according to the above.

For example, a sensor (for example, a sensor for measuring the relative distance from the cleaning surface) is provided near the cleaning unit 30 of the first embodiment.
Touch sensors, optical sensors, etc.) are provided at two or more points, and it is possible to measure the distance from the cleaning surface to the apparatus, the inclination, and the like in a planar manner based on measurement information from these points. If three or more sensors are provided, three-dimensional measurement is possible.

Specifically, if two touch sensors are provided on the left and right of the upper part of the cleaning device, the distance from the cleaning surface and the inclination in the left and right directions can be detected. By providing a similar sensor at the same time, the inclination in the vertical direction (elevation angle) can be simultaneously detected.

Then, based on the measurement information, if control is performed to adjust the moving direction (up, down, left, right, back and forth, etc.), inclination, stroke of the air cylinder, pressing pressure, and the like, the cleaning portion to be newly cleaned can be obtained. When the cleaning device is moved, it is possible to construct a cleaning device that can be automatically operated without requiring complicated manual adjustment by hand.

In the above embodiment, the method in which the high-pressure water cleaning and the brush cleaning are performed by an integrated apparatus has been described. However, the cleaning method according to the present invention is not limited to this. It can also be achieved by separately using a water washing device to wash the same washing part.

Further, when the unevenness of the cleaning surface is smaller than that of the cleaning part of the brush, it is important to appropriately select the configuration of the brush itself. It is effective to do. In this case, the cleaning device according to the embodiment of the present invention or the brush-only cleaning device, and the other high-pressure water cleaning device can be used in combination to perform cleaning operations corresponding to various cleaning surfaces. Become.

[0084]

As described above, according to the first aspect of the present invention, a cleaning brush slidably in contact with a cleaning surface and a high-pressure injection nozzle are used in combination, and the nozzle is provided on the supporting means by the moving brush by the moving means. The brushes are alternately arranged at intervals in the moving direction so as to be directed on the sliding contact path of the cleaning brush, and the support means can freely move three-dimensionally along the cleaning surface.
Since it is possible and the angle can be adjusted , unnecessary effects on the cleaning surface are surely removed by a synergistic effect of these.

This is different from the conventional linear cleaning method in that the cleaning part is flat and the cleaning operation is performed while moving the cleaning part, so that a wide cleaning surface can be secured. There is an advantage that the cleaning can be performed uniformly.

Further , in the present invention, since the cleaning brush and the nozzle are integrally provided on the supporting means, these driving mechanisms can be shared, the arrangement of the members is simplified, and the size of the apparatus can be reduced. It can be planned.

According to the second aspect of the present invention, the cleaning brush and the high-pressure injection nozzle that are in sliding contact with the cleaning surface are used in combination,
The nozzles are alternately arranged on the support means at intervals in the moving direction from the cleaning brush so as to be directed on the sliding path of the cleaning brush by the driving means.
The steps can be freely moved three-dimensionally along the cleaning surface and have corners.
Since the degree of adjustment can be adjusted and the supporting means is reciprocated or rotated, the cleaning portion is repeatedly cleaned with a brush and high-pressure jet water, so that unnecessary substances at the cleaning portion are reliably removed.

According to the fourth aspect of the present invention, the cleaning brush that slides on the cleaning surface and the high-pressure jet nozzle are used in combination, and the cleaning brush alternately and continuously follows the cleaning brush on the sliding contact track. The cleaning is performed by injecting the cleaning liquid at a high pressure to the contact position or before and after the sliding of the cleaning brush, and the supporting means is moved along the cleaning surface at three-dimensionally freely changing angles. According to the present invention, there is provided a method for reliably removing unnecessary substances on a cleaning surface by a synergistic effect.

Further, in any of the above-mentioned inventions, there is an advantage that the cleaning can be performed with a remarkably small amount of water as compared with the conventional high-pressure water cleaning alone. Accordingly, it is possible to prevent marine pollution caused by abandoning polluted water in the sea, and to provide a cleaning method effective for protecting the global environment.

The present invention can be used not only for cleaning the outer surface of a large vessel as shown in this embodiment, but also for cleaning other large faces, for example, for cleaning the inner wall of a tunnel. The application as a possible cleaning device is possible.
