. (54) DEVICE FOR CLEANING OF CASES OF WATER VEHICLES

one

This invention relates to a technique for cleaning water vehicles and can be used at docks to clean a ship's hull under water.

A device for cleaning the underwater part of the housing is known, which comprises a frame mounted on wheels on which there are ejector self-retaining means in the form of socket bearers with water nozzles installed at their center at an angle of 60 ° to the surface to be cleaned 1.

However, this device is suitable for cleaning only flat surfaces and cannot be used for cleaning curved surfaces from fouling and contamination, which is caused by the impossibility of adjusting the gap between the cleared and curvilinear surface of the ship's hull and the bell to exit the water fed to the bell.

Closest to the present invention is a device for cleaning water vehicles, comprising a frame installed with a movable 20, a receiving socket mounted on it with a nozzle connected to the pipeline

for water supply, and an outlet bell mounted on the receiving socket 2.

The disadvantages of the known device are the low intensity of cleaning and the impossibility of cleaning the curved hull areas in the tips and sides of the vessel, which is caused by the impossibility of ensuring a constant gap between the walls of the socket and the surface with a varying curvature.

The purpose of the invention is the intensification of cleaning and expansion of technological capabilities.

This goal is achieved by the fact that the device is equipped with spring-loaded brushes with the means of their rotation in the water flow, while the receiving socket on the inner side surface has pockets in which spring-loaded brushes are mounted.

In addition, each means for rotating the brush is made in the form of a propeller.

FIG. 1 shows the device, general view, cross section; in fig. 2 — node I in FIG. 1 (option to mount the brush in the socket); in fig. 3 is a section A-A in FIG. one.

The device comprises a movable frame 1 with a coupling 2 at the outlet of the receiving bell 3, an exhaust bell 4. The nozzle 2 is connected by a rotary nozzle 5 with a pipe b for supplying high pressure water. The nozzle 2 and the receiving socket 3 are the self-retaining means of the device on the surface being cleaned during operation. In the receiving socket 3 in the pockets 7, spring-loaded brushes 8 are fixed with the possibility of opposite rotation. The inlet 9 of the pocket 7 with the valve 10 for controlling the flow of water can be located on the side of the gap between the receiving mouth 3 and the surface 11 to be cleaned {Fig. 1) or in the wall of the socket 3 (eig. 2).

Each brush 8 is spring-loaded by a spring 12 from the side of the support 13 and the stop 14 on the rotational shaft 15 with the stop 16 of its vertical movement and the tool 17 of rotation of the brush, for example the rowing BJifiTOM. C. heat 2 is inclined to the surface to be cleaned at an angle, preferably 45–60 °. which contributes to the normal operation of the means of self-retention. The number of nozzles 2 and receiving sockets 3 with outlet sockets on frame 1 is determined by the pattern of the surface to be cleaned in a single pass, while the brushes 8 are positioned with overlapping of the surface being cleaned, preferably in a chessboard pattern.

The handle 18 is intended for manual or mechanized movement of the apparatus on the surface being cleaned.

The device works as follows.

The frame 1 on the rollers with the help of the handle 18 is moved along the surface being cleaned 11. Water under pressure from the pipe 6 by the nozzle 5 is fed into the nozzle 2, in which it is accelerated. A stream of water flowing at high speed from the nozzle 2 into the outlet socket 4 creates a discharge in it, as a result of which water is sucked into the reception socket 3 through pocket 7 and the gap between the cleaning surface and the edges of the reception socket 3. Continuous water flow in the pockets 7 causes the rotation of the brush 8,

which smooth out the surface from fouling, and the continuous flow of water in the receiving socket 3 tears off the fouling from the surface being cleaned and, together with the cleaning products, throws it out through the outlet socket 4, cleaning the surface.

The shutter 10 of the cross section of the inlet 9 is provided to regulate the flow of water through the pocket 7 and the speed of rotation of the brush 8. With a change in the curvature of the surface being cleaned, the brush 8 is automatically pressed by the springs 12.

Simultaneous cleaning with water flow and stripping with spring-loaded brushes set in motion by the same nozzle sharply intensifies the process of cleaning the surface of the vessel, since the dependence of the cleaning process on the size of the gap between the wall of the socket and the surface to be cleaned is eliminated, which makes the device universal.
