Description

Technical Field

[0001] This utility model relates to the field of underwater cleaner technology, specifically a cavitation jet underwater cleaner that is easy to operate. Background Technology

[0002] Cavitation jet underwater cleaners are advanced cleaning devices that combine the cavitation effect with the principle of high-pressure water jets. Primarily used for underwater cleaning operations, they generate cavitation bubbles through specially designed nozzles. These bubbles rapidly expand and burst in low-pressure areas, releasing enormous energy to form powerful shock waves and micro-jet streams. This allows them to penetrate and remove dirt and marine organisms adhering to object surfaces. Cavitation jet underwater cleaners are highly efficient and environmentally friendly underwater cleaning equipment, widely used in various underwater cleaning scenarios, and possess significant advantages and application value. However, current cavitation jet underwater cleaners still have the following shortcomings:

[0003] For example, patent document CN219668449U discloses an underwater hull cavitation jet cleaning device. This underwater hull cavitation jet cleaning device can effectively improve the water washing and cleaning effect on the hull structure. Compared with traditional devices, the shell structure of this device is more compact, making it easier for operators to carry and move the device. However, it requires manual operation of the cleaning head to extend and retract, which makes it less convenient and flexible in actual operation.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a cavitation jet underwater cleaner that is easy to operate. Utility Model Content

[0005] The purpose of this invention is to provide a convenient cavitation jet underwater cleaner to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient-to-operate cavitation jet underwater cleaner, comprising a cleaner body and a take-up and release assembly. A fixed roller is installed at the front end of the upper surface of the cleaner body. The take-up and release assembly is disposed on the surface of the cleaner body and includes a support frame, a left fixed plate, a right fixed plate, a servo motor, a connecting rod, a take-up drum, a cleaner hose, and a cavitation jet cleaning disc. The support frame is disposed on the upper front surface of the cleaner body, and a left fixed plate is installed on the upper left side of the support frame. A right fixed plate is disposed on the upper right side of the support frame, and a servo motor is installed on the right surface of the right fixed plate. The output end of the servo motor is connected to a connecting rod via a coupling, and a take-up drum is disposed on the outer surface of the connecting rod.

[0007] Furthermore, a cleaner hose is wound around the surface of the winding drum, and a cavitation jet cleaning disc is installed at the outer end of the cleaner hose.

[0008] Furthermore, a placement groove is provided on the upper surface of the rear end of the cleaner body, and the inner side of the placement groove is engaged with the surface of the cavitation jet cleaning disc.

[0009] Furthermore, an auxiliary handle is installed on the rear side of the cleaner body, and casters are provided on the lower side of the cleaner body.

[0010] Furthermore, the winding drum is an integrated structure, and the inner surface of the winding drum is tightly connected to the outer surface of the connecting rod.

[0011] Furthermore, a fixing frame is installed on the upper surface of the front end of the cleaner body, and the surface of the fixing frame is provided with auxiliary components for assisting winding.

[0012] Furthermore, the auxiliary component includes a support bar, a fixing bolt, and a connecting crossbar. The support bar is slidably connected to the inner surfaces of both ends of the fixing frame, and the upper ends of both sides of the fixing frame are threaded with fixing bolts. The connecting crossbar is installed on the upper surface of the support bar.

[0013] Furthermore, the auxiliary component also includes a movable shaft and an auxiliary groove, and the movable shaft is rotatably connected to the end of the connecting bar away from the support bar, and the auxiliary groove is installed on the outer end of the movable shaft.

[0014] This invention provides a convenient cavitation jet underwater cleaner with the following advantages:

[0015] 1. This utility model features a retraction and deployment assembly, which includes a support frame, a left fixed plate, a right fixed plate, a servo motor, a connecting rod, a winding drum, a cleaning hose, and a cavitation jet cleaning disc. In use, the servo motor is activated, causing it to rotate the connecting rod along the surface of the left fixed plate. This, in turn, drives the winding drum to rotate, automatically winding or lowering the cleaning hose. This, in turn, causes the cavitation jet cleaning disc to automatically rise and fall, facilitating underwater cleaning operations. This allows the device to automatically retract and deploy the cleaning disc without manual operation, making it more convenient and practical.

[0016] 2. This utility model incorporates an auxiliary component, which includes a support bar, a fixing bolt, and a connecting crossbar. The auxiliary component also includes a movable shaft and an auxiliary groove. During use, the support bar's height can be adjusted via a sliding connection between its inner ends and the inner sides of the fixing frame. After adjusting the support bar to a suitable height, the connection between the support bar and the fixing frame is secured via a threaded connection of the fixing bolt. When extending or retracting the cleaning hose, the hose is placed inside the auxiliary groove. During extension or retraction, the auxiliary groove rotates via the movable shaft under force, preventing jamming. This allows the device to adjust the auxiliary support height for the cleaning hose as needed, making the auxiliary support more flexible and less prone to jamming. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3 As shown, a convenient cavitation jet underwater cleaner includes a cleaner body 1 and a take-up assembly 3. A fixed roller 2 is installed at the front end of the upper surface of the cleaner body 1. The take-up assembly 3 is disposed on the surface of the cleaner body 1 and includes a support frame 301, a left fixed plate 302, a right fixed plate 303, a servo motor 304, a connecting rod 305, a take-up drum 306, a cleaner hose 307, and a cavitation jet cleaning disc 308. The support frame 301 is disposed on the upper front surface of the cleaner body 1, and a left fixed plate 302 is installed on the upper left side of the support frame 301. A right fixed plate 303 is disposed on the upper right side of the support frame 301, and a servo motor 304 is installed on the right surface of the right fixed plate 303. The output end of the servo motor 304 is connected to the connecting rod 305 through a coupling, and a take-up drum 306 is disposed on the outer surface of the connecting rod 305.

[0023] The specific operation is as follows: When in use, start the servo motor 304, so that the servo motor 304 drives the connecting rod 305 to rotate along the surface of the left fixed plate 302, and then drives the winding drum 306 to rotate through the connecting rod 305, so that the winding drum 306 automatically winds up or lowers the cleaning hose 307, and then drives the cavitation jet cleaning disc 308 to automatically rise and fall, so as to facilitate underwater cleaning operations.

[0024] Please refer to Figure 1 and Figure 3 The surface of the take-up drum 306 is wound with a cleaner hose 307, and a cavitation jet cleaning disc 308 is installed at the outer end of the cleaner hose 307. A placement groove 4 is opened on the upper rear surface of the cleaner body 1, and the inner side of the placement groove 4 is engaged with the surface of the cavitation jet cleaning disc 308. An auxiliary handle 5 is installed on the rear side of the cleaner body 1, and a movable wheel 6 is provided on the lower side of the cleaner body 1. The take-up drum 306 is an integrated structure, and the inner surface of the take-up drum 306 is tightly connected to the outer surface of the connecting rod 305. A fixing frame 7 is installed on the upper front surface of the cleaner body 1, and a fixing frame 7 is provided. The frame 7 is provided with an auxiliary component 8 for assisting winding. The auxiliary component 8 includes a support bar 801, a fixing bolt 802 and a connecting crossbar 803. The support bar 801 is slidably connected to the inner surfaces of both ends of the fixed frame 7, and the fixing bolt 802 is threaded to the upper ends of both sides of the fixed frame 7. The connecting crossbar 803 is installed on the upper surface of the support bar 801. The auxiliary component 8 also includes a movable shaft 804 and an auxiliary groove 805. The movable shaft 804 is rotatably connected to the end of the connecting crossbar 803 away from the support bar 801, and the auxiliary groove 805 is installed on the outer end of the movable shaft 804.

[0025] The specific operation is as follows: During use, the height of the support bar 801 can be adjusted by sliding the support bar 801 to the inner side of both ends of the fixed frame 7. After adjusting the support bar 801 to a suitable height, the connection between the support bar 801 and the fixed frame 7 is fixed by the threaded connection of the fixing bolt 802. When retracting or extending the cleaning hose 307, the cleaning hose 307 is placed inside the auxiliary groove 805. During the retraction or extension process, the auxiliary groove 805 can rotate through the movable shaft 804 after being subjected to force to prevent it from getting stuck during the retraction or extension process.

[0026] In summary, as Figures 1 to 3 As shown, this easy-to-operate cavitation jet underwater cleaner is used by first adjusting the height of the support bar 801 by sliding the support bar 801 to the inner sides of both ends of the fixed frame 7. After adjusting the support bar 801 to a suitable height, the connection between the support bar 801 and the fixed frame 7 is fixed by the threaded connection of the fixing bolt 802. When retracting or extending the cleaner hose 307, the cleaner hose 307 is placed inside the auxiliary groove 805. During the retraction or extension process, the auxiliary groove 805 can rotate through the movable shaft 804 after being subjected to force to prevent jamming during the retraction or extension process. The servo motor 304 is started, which drives the connecting rod 305 to rotate along the surface of the left fixed plate 302. Then, the connecting rod 305 drives the winding drum 306 to rotate, so that the winding drum 306 automatically retracts or lowers the cleaner hose 307, thereby driving the cavitation jet cleaning disc 308 to automatically rise and fall, facilitating underwater cleaning operations.
