Problems solved by technology

Due to the simultaneous injection of two nozzles of this type of nozzle, the pressure loss of the water gun is relatively large, and the performance requirements of the high-pressure water jet generator are also improved.
On the other hand, underwater cleaning operators often work under the load of heavy diving equipment. How to improve the moving efficiency of underwater cleaning operators is also an important issue.

Embodiment Construction

[0022] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] like figure 1 As shown, this embodiment is an underwater high-pressure water jet cleaning spray gun, including a nozzle 08, a spray rod, a step-down hydraulic cylinder, a rack and pinion adjustment knob, a pulse width modulation (PWM) DC motor governor 18, an underwater Thruster 01 and other components.

[0024] In this embodiment, the pressure-reducing hydraulic device includes a plunger 11 , a piston 12 , a piston cylinder 10 , a spring 13 and a rack 14 connected to the piston. The gear refers to the PWM knob 15 installed inside the spray gun, the circumference of the PWM knob 15 is a gear surface, and the piston 10 drives the rack 14 to rotate the knob during the movement to control the speed of the propeller.

[0025] The voltage adjustment knob 16 refers to the armature voltage regulator installed on the outer surface of the spray gun, wh...

Abstract

The invention discloses a high-pressure water jet cleaning spray gun. The high-pressure water jet cleaning spray gun comprises a spray rod. A spray gun pipeline is formed in the spray rod. The first end of the spray rod is connected with a spray nozzle. The spray nozzle communicates with the spray gun pipeline. A water gun connector is arranged on the spray rod. The water gun connector communicates with the spray gun pipeline. The second end of the spray rod is provided with a propelling device. The propelling device can generate propelling force towards one side of the spray nozzle. The high-pressure water jet cleaning spray gun has the advantages that under the condition that underwater cleaning personnel conduct cleaning operation at water jet pressure changing randomly, the rotation speed of the propelling device of the high-pressure water jet cleaning spray gun can be automatically adjusted so that the recoil force generated by the water jet can be rapidly eliminated; and in this way, the safety of the operation personnel can be guaranteed, and the underwater cleaning efficiency can also be improved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing underwater cleaning devices, and in particular relates to a recoilless spray gun for cleaning underwater with high-pressure water jets, which is used for cleaning underwater parts of ships and underwater facilities. Background technique [0002] As we all know, due to the strong corrosion of seawater and the strong adhesion of marine organisms, the underwater parts of ships, submarine oil facilities, power generation facilities, etc., make the surface of the underwater parts adhere to shellfish, rust scales and rust spots that are difficult to remove. It not only affects the service life of such facilities, but also increases the consumption cost of fuel and other energy sources. In recent decades, high-pressure water jet technology has played a lot of roles in the cleaning of these underwater facilities as a relatively effective cleaning technology. Compared with other cleaning methods, th...
