Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] This embodiment provides an easy-to-operate recoilless underwater cavitation cleaning spray gun. The spray gun has a good cleaning effect and is in a recoilless state during use with strong operability.

[0031] The structure of the cleaning spray gun is as follows: figure 1 As shown, it includes a gun handle 1, a spray gun connector 2, a positioning tool 3, a cavitation cleaning nozzle 4, a steady flow pipe 17, an anti-spray nozzle 6 and an unloading protection pipe 7. In this embodiment, the spray gun connecting body 2 is an "I-shaped" structure welded by three sections of hollow cylinders, and its central hole runs through to transport high-pressure liquid. Wherein the open end of the horizontal hollow cylinder located below is threadedly connected to the gun handle 1, and the end of the gun handle 1 is equipped with a quick-change ...

Abstract

The invention discloses an easily-operated type recoilless underwater cavitation cleaning spray gun which is composed of a gun handle, a spray beam, a cavitation spray nozzle, a back spray nozzle, an unloading protection tube and other accessories. The gun handle, the cavitation spray nozzle and the back spray nozzle are connected with the spray beam through threads, and a quick-change connector is mounted at the lower end of the gun handle and can be used for being connected with a high-pressure hose. The cavitation spray nozzle and the back spray nozzle with water flow spraying directions opposite to each other are mounted on the same axis, so that recoil of the spray gun can be eliminated. Light floating body materials in the accessories can provide buoyancy force for the spray gun to enable the spray gun to be in a state of zero buoyancy force; through a positioning jig, the spray gun is enabled to be at the best cleaning angle when used underwater; the unloading protection tube provided with strip-shaped holes is mounted on the outer portion of the back spray nozzle, a function of unloading is achieved, and safety of operating personnel can be protected.

Description

technical field [0001] The invention relates to a cleaning spray gun, in particular to an easy-to-operate recoilless underwater cavitation cleaning spray gun. Background technique [0002] Marine biofouling refers to animals, plants and microorganisms that are fixed or inhabited on the underwater solid surface of ships, platforms and various artificial facilities, and have adverse effects on human economic activities. These marine fouling organisms increase the fuel consumption of ships, threaten the safety of platforms, and affect the quality and output of aquaculture. They must be removed. [0003] At present, the main methods of biological cleaning of ship fouling include brush shovel cleaning, ultraviolet cleaning, high temperature hot water surface treatment, ultrasonic cleaning, ordinary high pressure water cleaning and cavitation water jet cleaning and other methods. Considering the degree of damage to the protective layer, environmental friendliness, degree of harm ...
