DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0026] like Figure 1As shown in the figure, a high-pressure rust removal and cleaning disc adaptive adjustment device includes a cleaning arm 1, a first fixed shaft 2, a second fixed shaft 3, a cleaning frame 4, and a cleaning disc 5. The structure of the cleaning arm adopts the structure shown in the utility model patent with the patent number CN202021091955.X. By controlling the position of the cleaning arm, the cleaning and rust removal position of the cleaning disc can be adjusted. The specific structure will not be elaborated here. The first fixed shaft and the second fixed shaft are of an integral structure and perpendicular to each other. A first shaft sleeve 6 is rotatably connected to the outside of the first fixed shaft, and a second shaft sleeve 7 is rotatably connected to the outside of the second fixed shaft. The first shaft sleeve is connected to the cleaning arm, which can make the cleaning frame drive the cleaning disc to swing left and right in the direction of the cleaning arm. The second shaft sleeve is connected to the cleaning frame, and the cleaning frame is connected to the cleaning disc, which can make the cleaning frame drive the cleaning disc to swing back and forth in the direction of the cleaning arm, that is, to realize the deflection of the cleaning disc in four directions, effectively improving the adaptive adjustment ability of the cleaning disc, improving the fitting effect between the cleaning disc and the hull, and enhancing the ability of cleaning and rust removal. The first shaft sleeve and the cleaning arm are assembled and connected by bolts or screws 12, and the second shaft sleeve and the cleaning frame are assembled and connected by bolts or screws, which is convenient for the disassembly and assembly among the cleaning frame, the cleaning arm, the first shaft sleeve and the second shaft sleeve. Combined with Figure 2 As shown in the figure, the number of cleaning discs is three. The three cleaning discs are located in the same plane and distributed in a "pin" shape, which can effectively increase the cleaning area and enhance the cleaning and rust removal efficiency and ability. Symmetrically connected to both sides of each cleaning disc are side shafts 13. Each side shaft is rotatably connected to the cleaning frame. The side shafts on the three cleaning discs are parallel to each other, further improving the adaptive performance of the cleaning discs.

[0027] Combined with Figure 1 、 Figure 3 and Figure 4 As shown in the figure, in order to improve the stability and safety of the overall structure, the overall structure of the first fixed shaft and the second fixed shaft is cross-shaped. The number of both the first shaft sleeve and the second shaft sleeve is two. The two first shaft sleeves are symmetrically distributed at both ends of the first fixed shaft, and the two second shaft sleeves are symmetrically distributed at both ends of the second fixed shaft.

[0028] Combined with Figure 3 、 Figure 4 and Figure 5As shown, a lubricating oil filling hole 8 is provided on one side of the connection between the first fixed shaft and the second fixed shaft, and a first-level diversion hole 9 is provided inside each of the first fixed shaft and the second fixed shaft. One end of each first-level diversion hole is connected to the lubricating oil filling hole, and the other end is connected to multiple second-level diversion holes 10 provided in the first fixed shaft or the second fixed shaft. The connection between the first sleeve and the first fixed shaft, and the connection between the second sleeve and the second fixed shaft are respectively connected to the corresponding second-level diversion holes. The staff can regularly add lubricating oil to the lubricating oil filling hole. The lubricating oil enters the first-level diversion hole along the lubricating oil filling hole, and is then diverted from the first-level diversion hole to the second-level diversion hole, thereby effectively improving the working performance of the bearings between the first sleeve and the first fixed shaft and between the second sleeve and the second fixed shaft, and extending the service life of the equipment. In order to prevent debris or dust from entering the lubricating oil filling hole, a plug 11 is threadedly connected to the orifice of the lubricating oil filling hole for easy disassembly and assembly.

[0029] The working principle of this utility model is as follows:

[0030] like Figure 6 As shown, the utility model is installed on the front end of a four-wheeled vehicle (as shown in the utility model patent with patent number CN202021091955.X), and the cleaning arm 1 is controlled to rise and fall or move left and right to adjust the position of the cleaning disc 5. When one side of the cleaning disc 5 contacts the surface of the ship, the cleaning disc 5 will use the rotational connection between the first fixed shaft 2 and the first shaft sleeve 6, the rotational connection between the second fixed shaft 3 and the second shaft sleeve 7, and the rotational connection between the side shaft 13 and the cleaning frame 4 to achieve adaptive adjustment of the angle along different curved surfaces, so that the opening of the cleaning disc 5 is closely fitted with the surface of the hull, thereby improving the cleaning effect.

[0031] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
