Description

Technical Field

[0001] The invention belongs to the technical field of ship cleaning, and in particular relates to a cleaning disc with a nozzle that can be self-adjusted. Background Art

[0002] With the advancement of science and technology and the rapid development of industry, my country's shipbuilding industry has developed rapidly. During the shipping process, the bottom of the ship is immersed in seawater for a long time and is prone to rust. In order to ensure the safety of ship shipping, the rusted parts of the bottom of the ship need to be removed regularly. At present, ultra-high pressure water jets are often used to clean and remove rust on the surface of the ship. The ultra-high pressure water jet rust removal process uses clean water as the rust removal medium to form a strong jet impact force to remove the rust layer without adding any chemical substances. The whole process of this rust removal process is mechanized and wet-operated, and no dust is generated. The waste scraps and wastewater generated by rust removal are completely recycled and filtered. It is a new green ship repair process.

[0003] When using ultra-high pressure water jet to remove rust, a cleaning disc is required. However, due to the different surface curvatures of different parts of the ship, such as the large curvature of the left and right sides of the ship, and the small curvature of the bow and stern, and the surface area of ​​the left and right sides of the ship is much larger than the existing bow and stern surface area, the existing cleaning disc cleans the bow and stern after cleaning the left and right sides of the ship. Due to the small curvature of the bow and stern, the distance between the nozzles on the cleaning disc and the ship surface is different, resulting in different impact forces when the water from different nozzles is sprayed onto the ship surface, affecting the controllability and stability of the impact force of ultra-high pressure water on the ship surface, thereby affecting the overall rust removal effect. Summary of the invention

[0004] In view of the problem that when the existing cleaning disc cleans the surface of a ship, due to the different surface curvatures of different parts of the ship, the distances between the nozzles on the cleaning disc and the surface of the ship are different, resulting in different impact forces when water from different nozzles is sprayed onto the surface of the ship, affecting the controllability and stability of the impact force of ultra-high pressure water on the surface of the ship. The present invention provides a cleaning disc with adaptive adjustment of the nozzles, which can ensure that the first universal wheel abuts against the surface of the ship in real time through a first compression spring during operation, and the arrangement of the first bellows enables the first universal wheel to move up and down, so as to ensure that the distance between the nozzle close to the first universal wheel and the surface of the ship remains unchanged.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0025] The cleaning disc with adaptive nozzle adjustment of the present invention is as follows: Figure 1-2 As shown, it includes a disc body 1, a main water pipe 2, a water distribution pipe 3 and a connecting block 4. The disc body 1 is provided with a main water pipe 2 and a water distribution pipe 3 which are interconnected through a second corrugated pipe 32. Two groups of water distribution pipes 3 are symmetrically arranged in the disc body 1, and the second corrugated pipe 32 is a three-way pipe fitting. Several nozzles 33 for spraying water are fixed below the water distribution pipe 3, so that ultra-high pressure water flows through the main water pipe 2, the second corrugated pipe 32, the water distribution pipe 3 in sequence, and finally sprays from the nozzle 33 to the area to be derusted. An active cavity 13 is provided at the connection between the disc body 1 and the main water pipe 2, a limiting block 21 is fixed on the main water pipe 2 and the limiting block 21 is slidably connected in the active cavity 13, a first compression spring 22 is provided at the connection between the upper end of the active cavity 13 and the limiting block 21, a first bellows 24 is provided above the main water pipe 2, the first compression spring 22 can ensure that the first universal wheel 46 abuts against the surface of the ship in real time during operation, and the setting of the first bellows 24 enables the first universal wheel 46 to move up and down, so as to achieve that the distance between the nozzle 33 close to the first universal wheel 46 and the surface of the ship remains unchanged, that is, the adaptive adjustment of the nozzle 33 is achieved, and the pressure of the high-pressure water sprayed from the nozzle 33 close to the first universal wheel 46 to the surface of the ship remains unchanged, thereby avoiding the change of the nozzle distance to the cleaning surface affecting the pressure of the high-pressure water sprayed from the nozzle to the surface of the ship, and improving the controllability and stability of the impact force of ultra-high pressure water on the surface of the ship.

[0026] Combination Figure 3As shown, a matching first spherical cavity 41 and a first ball head 23 are respectively provided at the connection between the connecting block 4 and the main water pipe 2, and a matching first protrusion 411 and a first groove 231 are respectively provided on the first spherical cavity 41 and the first ball head 23, and the first protrusion 411 and the first groove 231 are arranged opposite to the water distribution pipe 3; a matching second spherical cavity 42 and a second ball head 31 are respectively provided at the connection between the connecting block 4 and the water distribution pipe 3, and the connecting block 4 is hinged with the main water pipe 2 and the water distribution pipe 3 through the cooperation of the first spherical cavity 41 and the first ball head 23, and the cooperation of the second spherical cavity 42 and the second ball head 31, so as to realize the rotation between the connecting block 4 and the main water pipe 2, and the connecting block 4 and the water distribution pipe 3. The first spherical cavity 41 and the first ball head 23 are respectively provided with a matching first protrusion 411 and a first groove 231, and the first protrusion 411 and the first groove 231 are arranged opposite to the water distribution pipe 3. On the one hand, when the main water pipe 2 rotates around the axis, the connection block 4 can be driven to rotate, and on the other hand, the rotation direction between the connection block 4 and the main water pipe 2 is limited, that is, the rotation direction of the connection block 4 around the first ball head 23 corresponds to the position where the water distribution pipe 3 is set. The second spherical cavity 42 and the second ball head 31 are respectively provided with matching second protrusions 421 and second grooves 311 at the upper and lower ends, which are used to limit the rotation direction between the connection block 4 and the water distribution pipe 3, so that the water distribution pipe 3 can only rotate up and down around the connection block 4, ensuring that the nozzle 33 is always facing downward. An intermediate cavity 43 for accommodating the second corrugated pipe 32 is provided in the connection block 4, which is used to provide sufficient space for the second corrugated pipe 32 when it is deformed, so as to avoid interference when the second corrugated pipe 32 is deformed. The connecting block 4 is divided into two halves, and the outer edges of the two halves of the connecting block 4 are fixedly connected to multiple sets of matching connecting plates 47, and each set of matching connecting plates 47 is connected by threaded fasteners, which is convenient for disassembly and assembly of the first ball head 23 and the second ball head 31.

[0027] The main water pipe 2 and the water branch pipe 3 are connected outside by a connecting block 4, and a wheel seat 44 is fixedly connected below the connecting block 4, and the wheel seat 44 is divided into two halves, and the two halves of the wheel seat 44 are respectively fixedly connected to the two halves of the connecting block 4, and are adapted to the two halves of the connecting block 4 to avoid hindering the disassembly and assembly of the two halves of the connecting block 4. The lower end of the wheel seat 44 is connected to the first universal wheel 46 through a bearing 45. When working, the first universal wheel 46 abuts against the surface of the ship in real time. At the same time, the setting of the bearing 45 can make the wheel seat 44 and the first universal wheel 46 not rotate synchronously.

[0028] The dish body 1 includes a dish body top 11 and a dish body side 12, between which an annular flexible corrugated sleeve 52 having a diameter adapted to the diameter of the dish body side 12 and a plurality of groups of second compression springs 51 are fixedly connected, and the flexible corrugated sleeve 52, the dish body top 11 and the dish body side 12 form a cleaning dish cover. Figure 4As shown, a circle of flexible corrugated sleeve 52 is provided on both sides of the second compression spring 51, and the second compression spring 51 is located in the space between the two layers of flexible corrugated sleeve 52. When the dish body 1 abuts against the surface to be cleaned for cleaning and rust removal, the setting of the flexible corrugated sleeve 52 can provide a closed environment for the dish body 1, and can also prevent water from splashing onto the second compression spring 51, causing the second compression spring 51 to rust easily, thus affecting the life of the second compression spring 51. The upper and lower ends of the flexible corrugated sleeve 52 are respectively installed on the top 11 and the side 12 of the dish body through the pressure strip 53, and the pressure strip 53 and the top 11 and the side 12 of the dish body are connected by threaded fasteners, so as to facilitate the disassembly and assembly of the flexible corrugated sleeve 52.

[0029] A circle of slide grooves 121 are arranged on the side portion 12 of the pan body at a position corresponding to the water distribution pipe 3, and a slider 34 sliding in the slide groove 121 is fixedly connected to one end of the water distribution pipe 3, so that the end of the water distribution pipe 3 connected to the side portion 12 of the pan body can move up and down with the side portion 12 of the pan body, and further the distance between the nozzle 33 on the water distribution pipe 3 close to the side portion 12 of the pan body and the surface of the ship remains constant, and the pressure of the high-pressure water sprayed from the nozzle 33 close to the side portion 12 of the pan body to the surface of the ship remains constant, avoiding the change of the nozzle distance from the cleaning surface to affect the pressure of the high-pressure water sprayed from the nozzle to the surface of the ship, and improving the controllability and stability of the impact force of ultra-high pressure water on the surface of the ship. A third corrugated pipe 35 is arranged on the water distribution pipe 3 to ensure that the end of the water distribution pipe 3 will not be affected when it moves up and down. A pulley 341 is provided at the connection between the slider 34 and the slide groove 121, and the sliding friction between the slider 34 and the slide groove 121 is changed to rolling friction, thereby reducing the friction between the two, facilitating the slider 34 to move on the slide groove 121, and reducing the influence of the side portion 12 of the disc body on the rotation of the water distribution pipe 3. A second universal wheel 14 is fixedly connected to the bottom of the disc body 1, so that the second universal wheel 14 always abuts against the surface of the ship during operation.

[0030] The disc 1 is fixedly provided with a motor 61, which is connected to a transmission shaft 63 through a bevel gear set 62, and the transmission shaft 63 is connected to the main water pipe 2 through a spur gear set 64, so that the motor 61 controls the rotation of the main water pipe 2, and then controls the water distribution pipe 3 to rotate around the axis of the main water pipe 2, thereby improving the cleaning and rust removal effect. A circle of brushes 15 are arranged in an annular manner at the bottom of the disc 1, which can scrub the surface of the ship on the one hand, and separate the inner and outer surfaces of the disc 1 on the other hand, so that the inside of the disc 1 is a closed space.

[0031] The embodiments are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
