Abstract

PURPOSE:To improve the cleaning power in a cleaning device to remove shells and the like stuck on a hull by slanting a high pressure water pipe at a proper angle against the proceeding direction of a moving body in parallel with a cleaned face for bringing nozzles closer. CONSTITUTION:When the adhesive force to a hull 1 is weak, a nozzle bar 16 is separated to the maximum distance to cross the moving direction at right angles, and a valve 27 is opened to move a beam side traveling scaffold 2. Then, a high pressure water pump 40 is operated to jet water from each nozzle 19 with the oscillation by an oil pressure motor 21. For strengthening the jetting power, nozzles 1911-1914 are stopped by the valve 27, and the jetting power of nozzles 191-1910 is strengthened by that portion. For further strengthening, the nozzle bar 16 is slanted by the extension of an oil pressure cylinder 24 via lengthwise frame 8, widthwise frames 11, and square frames 10, and the jetting pattern width of each nozzles 191-1914 is set at l3. For strengthening furthermore, the valve 27 is closed, and the jetting pattern width of each nozzle 191- 1910 is set at l4. This construction permits to strengthen the cleaning power.

Description

[Detailed Description of the Invention] The present invention relates to a high-pressure water cleaning device, and its purpose is to remove shells, rust, etc. attached to the side walls and bottoms of ships and floating bodies, and to remove dirt from ground tanks. The goal is to efficiently contain and remove them.

Conventionally, as a method of removing deposits such as E1 shell and rust that are attached to the side walls and bottom of a ship, it has been considered to spray high-pressure water to remove them. When operating a spray gaff nozzle, increasing the amount of water and increasing the water pressure makes it difficult for the operator to support the nozzle due to the reaction force, which also increases the danger.

Therefore, it has been considered to use a mechanical device to hold the jet gas and configure multiple nozzles to remove the deposits using high-pressure water jetted from the multi-nozzles, but the adhesion force of the deposits is not strong or weak. However, it is difficult to remove strongly adhered deposits by simply spraying high aqua regia, and relatively high-pressure water is sprayed against weakly adhesive deposits. Doing so would be a waste of high-pressure water.

The present invention provides a high-pressure water cleaning device that solves these problems. The feature is that the subject eIc
A movable body that can move freely along the seepage surface, a high-pressure water pipe installed on the movable body, and a large number of high-pressure water pipes installed at appropriate intervals along the length of the pipe at locations facing the surface to be cleaned. High pressure water washing with high pressure water injection nozzle? In S5, an inclination device is installed to incline the piping at an appropriate angle with respect to the direction of repeated strikes of the movable body while being parallel or almost parallel to the surface to be cleaned. According to this configuration, the adhesion force of deposits can be reduced. The high-pressure water jet pattern can be freely adjusted according to the user's stubbornness.

Hereinafter, one embodiment of the present invention will be described based on the drawings. This embodiment relates to a high-pressure water cleaning device for a ship's hull.

], deposits can be removed over a range of width (11).

Next, if you want to increase the jetting force as described above, just close the pulse 4. This allows the nozzle (1911) to

) It is possible to remove deposits over a range of 1 to 30 degrees.Accordingly, the high-pressure water jetting force can be switched to two levels of strength and weakness without adjusting the capacity of the high-pressure water pump, making it easy to operate. In addition, if two or more pulps (goods) are provided, the high-pressure water can be switched to three or more stages.

Next, when you want to increase the jetting force even more than the above [7 #
Now, extend the piston rod (24B) of the hydraulic cylinder and move the nozzle par α peak in the direction of the arrow (Ii) through the sliding frame (G) to release the pulp and move it into the hydraulic cylinder. ) by extending the piston rod (25B) and inclining the nozzle per (a) with respect to the moving direction through the vertical beam (8), the horizontal beam Oυ and the rectangular frame αQ. You can do it quickly. In this situation, the spray pattern (b) of each nozzle (191) to (1914) becomes as shown in Fig. 1O, and the deposited material can be removed over the width (13). Furthermore, each pattern (b)
However, since the nozzle bar is tilted, the cleaned directions overlap each other, and there are no uncleaned areas.

Next, when you want to further increase the jetting force as described above,
Just close the pulp (goods). By this Noah: J
The high-pressure water sprayed from k (191) to (191o) is the strongest and can remove deposits over the width (14).

Next, a specific example of this embodiment will be described as shown in the attached table.

- Below margin - According to the configuration of the above embodiment, since the nozzles (191) to (1914) that eject in the fan-shaped pattern (-) are used, the nozzles (191) to (1914) and the hull (1 ) can be kept within 0.3 m, and there is no risk of high-pressure water splashing into the surrounding area and posing a danger to nearby workers. It is possible to achieve safety and labor savings.

Furthermore, since the cleaning power can be easily and instantly adjusted, it can be applied to everything from severe stains to mild stains, and can demonstrate a high degree of practicality. In other words, strong stains that could not previously be removed by hand can be cleaned, while mild stains can be cleaned at high speed, which not only improves efficiency but also saves water and electricity used for cleaning. can be achieved.

As described above, according to the high aqua regia cleaning device of the present invention, since the inclination device is provided to incline the high pressure water piping at an appropriate angle with respect to the traveling direction of the moving body in a state parallel to the surface to be cleaned or Vi approximately parallel to the surface to be cleaned, Even if there is a gap between each spray pattern when the nozzle is moved closer to the surface to be cleaned to increase the cleaning power, the surfaces cleaned by each pattern can overlap each other and the wood and cleaning materials can be cleaned easily. No parts arise.
