Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically relating to a handheld cleaning device. Background Technology

[0002] The hull of a ship, more precisely the underwater portion, the so-called "underwater hull," is particularly susceptible to wear and tear due to its constant contact with water. If we consider a new ship with an exceptionally clean hull, a thin layer of vegetation will form within days of its launch. After about a month, this vegetation layer hardens, and small shellfish begin to attach to the hull. Several months later, the vegetation layer almost becomes a hard shell that begins to damage the hull. To protect the hull, the vegetation layer and shellfish attachment must be removed regularly. Typically, two or three times a year, the ship is returned to dry dock and lifted from the water by crane for hull cleaning. Special treatments are required to remove the vegetation layer, followed by the application of an anti-vegetation agent to the hull. After maintenance is completed, the ship is returned to the water. Current ship maintenance procedures have various shortcomings because they require: completely lifting the ship out of the water, a very complex (and dangerous) operation for medium and large vessels, potentially requiring specialized cranes only available in ports of a certain size; manpower and specialized equipment to remove vegetation and shellfish attached to the hull; hull treatment including grinding the entire underwater hull, which generates harmful dust in the air; applying anti-vegetation paint to the hull, which is severely environmentally harmful; and finally, returning the ship to the water. Therefore, existing traditional cleaning methods are costly, inefficient, and environmentally unfriendly. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a handheld cleaning device to solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A handheld cleaning device includes a cleaning tray assembly and a handle fixedly connected to the cleaning tray assembly. A rotary joint is fixedly provided through the middle of the cleaning tray assembly. A high-pressure hose is connected through one end of the rotary joint, and a cavitation jet nozzle is rotatably connected to the other end. The cavitation jet nozzle is connected to the high-pressure hose through the rotary joint. The cavitation jet nozzle is laterally distributed inside the cleaning tray assembly, and cavitation jet cleaning nozzles are installed at both ends of the cavitation jet nozzle at an angle.

[0006] Furthermore, the cleaning disc assembly includes an upper cover, a connecting plate fixedly connected to the upper cover, and a lower cover fixedly connected to the connecting plate. The rotary joint is located in the middle of the upper cover, and the cavitation jet nozzle is located in the lower cover.

[0007] Furthermore, the upper cover is made of a buoyancy material.

[0008] Furthermore, two directional wheels and one omnidirectional wheel are installed at the edge of the connecting plate.

[0009] Furthermore, a sound-insulating ring is fitted onto the outer wall of the lower cover.

[0010] Furthermore, a manual ball valve is installed at the end of the high-pressure hose.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. When using this utility model to clean the outer surface of a ship, divers can hold this utility model in their hands to clean the hull without having to send the ship back to the dock, which greatly reduces cleaning costs.

[0013] 2. When this utility model is in use, the cavitation jet nozzle rotates in a circular motion within the lower cover of the cleaning disc assembly, forming a vacuum chamber inside the lower cover. This vacuum chamber can then be negatively pressure adsorbed onto the hull, resulting in good cleaning effect and high cleaning efficiency.

[0014] 3. When this utility model is in use, the cavitation jet nozzle is designed with a rotating angle distribution. It utilizes the recoil force of the water to drive the cavitation jet nozzle to rotate, thereby achieving area cleaning. This cleaning method is energy-saving and environmentally friendly.

[0015] 4. This utility model is equipped with a sound insulation ring, which can reduce cleaning noise and improve the comfort of use. Attached Figure Description

[0024] Example:

[0025] like Figures 1-2As shown, this utility model discloses a handheld cleaning device, including a cleaning tray assembly and a handrail 1 fixedly connected to the cleaning tray assembly. A rotary joint 2 is fixedly installed through the middle of the cleaning tray assembly. A high-pressure hose 3 is connected through one end of the rotary joint 2. A manual ball valve 12 is installed at the end of the high-pressure hose 3, and a cavitation jet nozzle 4 is rotatably connected to the other end. The cavitation jet nozzle 4 is connected to the high-pressure hose 3 through the rotary joint 2. The cavitation jet nozzle 4 is laterally distributed inside the cleaning tray assembly. Cavitation jet nozzles 5 are installed at both ends of the cavitation jet nozzle 4 at an angle. The cleaning tray assembly includes an upper cover 6, a connecting plate 7 fixedly connected to the upper cover 6, and a lower cover 8 fixedly connected to the connecting plate 7. The rotary joint 2 is located in the middle of the upper cover 6, and the cavitation jet nozzle 4 is located inside the lower cover 8. The upper cover 6 is made of buoyancy material. Two directional wheels 9 and one universal wheel 10 are installed at the edge of the connecting plate 7. A sound insulation ring 11 is fitted on the outer wall of the lower cover 8. Specifically, the working principle and effect of this device are as follows: 10-20 MPa water enters the inlet of manual ball valve 12 through high-pressure hose 3. When manual ball valve 12 is opened, 10-20 MPa water enters the outer shell of rotary joint 2. Because the local coordinate system at the corner of cavitation jet nozzle 4 is designed to be at a certain angle to the base coordinate system, the direction of the recoil force of the water is the same as the z-axis direction in the local coordinate system of cavitation jet nozzle 4. The recoil force has two components in the base coordinate system. One component, Fy, is along the -y-axis direction in the base coordinate system, and the other component, Fz, is along the -z-axis direction in the base coordinate system. The force component Fy drives the cavitation jet welding pipe in rotary joint 2 to rotate. The cavitation jet nozzle 4 is welded together with the jet welding mother pipe, thereby achieving area cleaning. The moving pipe in rotary joint 2 is fixed to the jet welding mother pipe with screws. The cavitation jet nozzle 5 provides recoil force, driving the entire device to move. Divers or workers hold onto the end of the handrail 1 to complete large-area cleaning operations. At the same time, the universal wheels 10 at the rear end allow for easy turning. As the cavitation jet nozzle 4 rotates in a circular motion, it creates a vacuum chamber inside the lower cover 8 of the cleaning disc assembly, using water pressure to adhere the entire device to the iron plate or ship hull.

[0026] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date.

Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
