[0033] On the basis of example 1, the scheme in example 1 is further refined in combination with the specific working mode as follows: Figures 1 to 4 As shown, see the following description in detail:

[0034] As a preferred embodiment, the limiting fixing frame 10 is provided with several groups, and the several groups of limiting fixing frames 10 are arranged in an equidistant interval mode. The two ends of the limiting fixing frame 10 are connected with the cleaning nozzle 9 and the fixing ring 8 through bolts respectively. Further, the high-pressure shock wave and micro-jet generated by the cavitation jet flow will make the cleaning nozzle 9 bear a large impact force. The equidistantly distributed multiple groups of limiting fixing frames 10 can uniformly disperse these impact forces to the fixing ring 8, bolts and the entire connecting structure, avoid local excessive stress leading to component damage, and tightly fix the cleaning nozzle 9 on the fixing ring 8 to avoid mutual movement between the two causing vibration.

Further, the soft pad 12 made of silica gel has a certain friction, which makes the operator hold the equipment better. The striped design increases the roughness of the surface of the handle 11, so that the operator can obtain greater friction when holding the handle 11, thereby holding the handle 11 more firmly, facilitating the movement, transportation and other operations of the cavitation jet flow pipe 1.

[0037] As a preferred embodiment, the inner cavity of the fixing ring 8 has a hole cavity for the water pipe to pass through. The standby connecting water pipe 6 and the main connecting water pipe 7 are respectively penetrated and welded in the inner cavities of the two groups of fixing rings 8 and are in communication with the cleaning nozzle 9. Further, the hole cavity of the fixing ring 8 provides accurate positioning for the standby connecting water pipe 6 and the main connecting water pipe 7, ensuring that the water pipes can accurately communicate with the cleaning nozzle 9, ensuring the accuracy and stability of the water flow path. By penetrating and welding the water pipes in the inner cavities of the fixing rings 8, a stable connection mode is formed, and the fixing ring 8 can provide additional support and fixing effect for the cleaning nozzle 9.

[0039] The working process of the utility model is as follows: first, the external water source delivers water into the cavitation jet pipe 1 through the water delivery pipe 13, the main water inlet 3 serves as the main water flow input channel in the normal working state, when the electric water valve 4 installed on one side of the main water inlet 3 is opened, the water flow flows to the cleaning nozzle 9 through the main connecting water pipe 7, providing a stable water flow for the cleaning nozzle 9, so that the cleaning nozzle 9 generates cavitation jet, realizing efficient cleaning operation, in this process, the flow sensor 5 on one side of the main water inlet 3 will monitor the water flow in real time, ensuring that the water flow state is normal, when the main water inlet 3 fails or the flow sensor 5 detects that the main water supply system has flow anomalies and other problems, the control system will send a signal to the electric water valve 4 at the main water inlet 3 to close it, and at the same time, open the electric water valve 4 at the standby water inlet 2, at this time, the water flow flows to the standby cleaning nozzle 9 through the standby connecting water pipe 6, ensuring that the cleaning work can continue, ensuring the continuity of the cleaning work;

[0040] The inner cavity of the fixing ring 8 leaves a hole cavity for the water pipe to pass through, providing accurate positioning for the standby connecting water pipe 6 and the main connecting water pipe 7, ensuring that the water pipe can accurately communicate with the cleaning nozzle 9, ensuring the accuracy and stability of the water flow path, at the same time, the fixing ring 8 can also provide additional support and fixing effect for the cleaning nozzle 9, the limiting fixing frame 10 arranged at equal intervals, the two ends of which are connected with the cleaning nozzle 9 and the fixing ring 8 through bolts respectively, can evenly disperse the large impact force borne by the cleaning nozzle 9 due to the high-pressure shock wave and microjet generated by the cavitation jet to the fixing ring 8, bolts and the entire connecting structure, avoiding local excessive stress leading to component damage, tightly fixing the cleaning nozzle 9 on the fixing ring 8, reducing vibration, protecting the connecting part, prolonging the service life of the component, the outer surface of the handle 11 is arranged in a striped manner, increasing the surface roughness, so that the operator can obtain greater friction when holding the handle 11, facilitating the movement, position adjustment and other operations of the cavitation jet pipe 1 underwater, the soft pad 12 made of silica gel has a certain friction, which can help the operator hold the equipment better, and works together with the handle 11 to facilitate the operation and transportation of the device, and the above is the working principle of the cavitation jet underwater cleaning device.
