Description

Technical Field

[0001] This application belongs to the technical field of underwater cleaning robots. More specifically, it relates to a jet cleaning disc. Background Art

[0002] Since the bottom of a ship is always below the waterline for a long time, with the increase of the usage time, algae, shellfish and crustacean organisms will inevitably attach to the bottom of the ship, and it is not easy to clean such biological attachments.

[0003] Currently, to effectively clean such attachments, generally an underwater robot is used to carry a jet cleaning disc and clean it by means of jet flow. However, in the aforementioned cleaning method, the jet cleaning disc is generally fixedly arranged at the bottom of the underwater robot, or can only move rigidly within a fixed direction range at the bottom of the underwater robot. As a result, when dealing with complex terrains caused by the attachment of algae, shellfish and crustacean organisms, the jet cleaning disc is extremely likely to be unable to climb over, get stuck, or the disc surface does not fit tightly with the ship's body, resulting in low cleaning efficiency. Utility Model Content

[0024] When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0025] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0026] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0028] Please refer to Figures 1 to 5 together, and now the jet cleaning disk provided by the embodiments of the present application will be described.

[0029] It can be understood that the jet cleaning disk described in the present application is used to be assembled at the bottom of an underwater cleaning robot to clean the biofouling on the part below the waterline of water surface equipment such as water surface vessels and floating buildings.

[0030] Refer to Figure 1 and Figure 2 、 Figure 4 and Figure 5, the jet cleaning disk of the present application includes a base 100 and a jet disk assembly 200. The jet disk assembly 200 is movably arranged on the base 100 and can move along at least two directions. For example, it can rotate around the base 100 and approach or move away from the base 100 along the thickness direction of the base 100 to better cross various attachments and clean the attachments.

[0031] Specifically, referring to Figures 1 to 5 , at least one jet disk assembly 200 is provided. Each jet disk assembly 200 includes a disk body 210 and a rotating jet device 220. A rotating cavity 211 is provided at the bottom of the disk body 210. The rotating jet device 220 is rotatably arranged in the rotating cavity 211. The rotating jet device 220 is connected to a high-pressure water source. When the high-pressure water source supplies water, the high-pressure water flow drives the rotating jet device 220 to rotate, thereby performing rotary spraying on the attachments to achieve the cleaning effect.

[0032] It should be understood that when multiple jet disk assemblies 200 are provided, each jet disk assembly 200 can be movably arranged on the base 100 separately, or each jet disk assembly 200 can be movably arranged on the base 100 synchronously; each disk body 210 can be provided with only one rotating cavity 211, or can be provided with multiple rotating cavities 211, and the specific is not limited thereto.

[0033] Furthermore, referring to Figure 1 and Figure 2 , a buffer and shock-absorbing part 300 is connected between the base 100 and the jet disk assembly 200. When the jet disk assembly 200 crosses the attachment, the jet disk assembly 200 first rotates relative to the base 100 to move from in front of the attachment to the attachment. When the jet disk assembly 200 is completely located on the attachment, the jet disk assembly 200 moves relative to the base 100 along the thickness direction approaching the base 100. After the jet disk assembly 200 crosses the attachment, the jet disk assembly 200 rotates relative to the base 100 and then moves along the thickness direction away from the base 100. During the entire movement process of crossing the attachment, on the one hand, the buffer and shock-absorbing part 300 can relieve or absorb the vibration generated during the crossing process, so that the movement of the jet disk assembly 200 is more stable; on the other hand, it can also avoid the problem of reduced service life of components such as the rotating jet device 220 on the jet disk assembly 200 due to long-term vibration; on the other hand, the buffer and shock-absorbing part 300 can make the movement degree of freedom of the jet disk assembly 200 larger, so that the jet disk assembly 200 can closely adhere to the surface of the attachment during the crossing process, thereby effectively improving the cleaning efficiency.

[0034] Referring to Figures 1 to 5, in some embodiments, there are at least two buffer shock-absorbing parts 300, and different buffer shock-absorbing parts 300 are connected to different positions of the jet disk assembly 200 and the base 100. In this way, the flexibility of the jet disk assembly 200 is better, so as to better conform to the surface of the attachment.

[0035] In some embodiments, there are at least two jet disk assemblies 200 independently provided, and a buffer shock-absorbing part 300 is connected between each jet disk assembly 200 and the base 100.

[0036] Reference Figures 1 to 5 , in some embodiments, two rotating jet injectors 220 are rotatably arranged on the disk body 210.

[0037] Reference Figure 3 , in some embodiments, a grid-shaped cover body 230 is arranged at the bottom of the disk body 210 at the opening of the rotating cavity 211, and the rotating jet injector 220 is arranged inside the cover body 230. In this way, by arranging the cover body 230 at the opening of the rotating cavity 211, it is possible to avoid the situation that when the jet disk assembly 200 crosses the attachment, a sharp attachment invades the rotation plane of the rotating jet injector 220 and collides with the high-speed rotating rotating jet injector 220, resulting in damage to the rotating jet injector 220.

[0038] Reference Figure 1 and Figure 2 、 Figure 4 and Figure 5 , in some embodiments, the jet disk assembly 200 is rotatably arranged on the base 100. Specifically, one end of the jet disk assembly 200 is rotatably arranged on the base 100; the other end is flexibly connected to the base 100. Correspondingly, the buffer shock-absorbing part 300 at least includes a first buffer shock-absorbing part 310 and a second buffer shock-absorbing part 320.

[0039] Reference Figure 2 、 Figure 4 and Figure 5 , wherein, both ends of the first buffer shock-absorbing part 310 are rotatably connected to the base 100 and the disk body 210 at the same time; that is, the first buffer shock-absorbing part 310 is responsible for the flexible connection between the jet disk assembly 200 and the base 100. Specifically, the first buffer shock-absorbing part 310 includes a first connection seat 311, a first rotating shaft 312, a second rotating shaft 313, and a first shock-absorbing spring 314 connecting the first rotating shaft 312 and the second rotating shaft 313. The first connection seat 311 is fixedly arranged on the disk body 210, the first rotating shaft 312 is rotatably arranged on the base 100, and the second rotating shaft 313 is rotatably arranged on the connection seat.

[0040] When the other end of the jet disk assembly 200 rotates relative to the base 100, the first rotating shaft 312 rotates relative to the base 100, and the second rotating shaft 313 rotates relative to the connecting seat. At the same time, the first shock-absorbing spring 314 is stretched or compressed synchronously. When the first shock-absorbing spring 314 is compressed, the jet disk assembly 200 moves to the surface of the attachment. When the first shock-absorbing spring 314 is stretched, the jet disk assembly 200 crosses over the surface of the attachment.

[0041] Further, at least two first shock-absorbing springs 314 are arranged side by side in the axial direction of the first rotating shaft 312. In this way, the shock-absorbing effect of the first shock-absorbing portion 310 is better.

[0042] Reference Figure 1 and Figure 2 One end of the second shock-absorbing portion 320 is fixedly connected to the base 100, and the other end of the second shock-absorbing portion 320 is rotatably connected to the disk body 210. Specifically, the second shock-absorbing portion 320 includes a second connecting seat 321, a third connecting seat 322, a fourth connecting seat 323, and a second shock-absorbing spring 324; the second connecting seat 321 is fixedly arranged on the base 100, the fourth connecting seat 323 is fixedly arranged on the disk body 210, the third connecting seat 322 is rotatably arranged on the fourth connecting seat 323, and the second shock-absorbing spring 324 connects the second connecting seat 321 and the fourth connecting seat 323.

[0043] When the jet disk assembly 200 rotates relative to the base 100, the fourth connecting seat 323 rotates relative to the third connecting seat 322; during the process of the jet disk assembly 200 moving to the surface of the attachment, the second shock-absorbing spring 324 is compressed, and after the jet disk assembly 200 crosses over the surface of the attachment, the second shock-absorbing spring 324 is stretched.

[0044] Further, two second shock-absorbing springs 324 are arranged side by side in the length direction perpendicular to the disk body 210, and the two second shock-absorbing springs 324 are respectively arranged on both sides of the rotation axis of the third connecting seat 322. In this way, the shock-absorbing effect of the second shock-absorbing portion 320 is better.

[0045] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
