Description

Technical Field

[0001] The utility model relates to the technical field of cleaning hollow objects with special equipment, in particular to a limited space cleaning device. Background Art

[0002] Confined space refers to a closed or partially closed space that is relatively isolated from the outside world, with narrow entrances and exits, where workers cannot work for a long time, and where natural ventilation is poor, which is prone to the accumulation of toxic, harmful, flammable and explosive substances or insufficient oxygen content. Confined spaces are divided into three categories: 1. Enclosed equipment: such as cabins, storage tanks, vehicle tanks, reaction towers (kettles), refrigerators, pressure vessels, pipelines, flue boilers, etc.; 2. Underground confined spaces: such as underground pipelines, basements, underground warehouses, underground projects, culverts, tunnels, culverts, pits, waste wells, cellars, sewage pools (wells), biogas tanks, septic tanks, sewers, etc.; 3. Above-ground confined spaces: such as storage rooms, wine lees pools, fermentation pools, garbage stations, greenhouses, cold storages, granaries, silos, etc.

[0003] The existing confined space cleaning operation requires personnel to enter the confined space and use high-pressure water pipes to clean and sweep; the disadvantage is that personnel need to enter the confined space to perform the operation, and there are risks of poisoning, suffocation, electric shock, heat stroke, etc. when entering the operation. Manual cleaning of confined spaces also has the disadvantages of high labor intensity and low work efficiency. In order to solve the technical problems of personal injury and high labor intensity in the process of personnel entering the confined space for cleaning, it is necessary to design a device that can automatically clean in a confined space to replace manual labor, prevent personal injury to personnel, and improve the cleaning effect.

[0004] The patent with publication number CN107737781A discloses an automatic cleaning machine for cleaning a pulp pool and a cleaning method thereof. The high-pressure washing 360-degree automatic rotation system comprises a high-pressure water pump, a long rod rotating joint, a long rod with a high-pressure water pipeline inside, a long rod rotating device, a nozzle rotating joint and a nozzle rotating device. The long rod rotating joint is movably connected to the long rod, the water inlet end of the long rod rotating joint is connected to the high-pressure water pump, the water outlet end of the long rod rotating joint is connected to the high-pressure water pipeline of the long rod, the long rod rotating device is arranged on the long rod and drives the long rod to rotate axially, the nozzle rotating device is arranged on the long rod, a nozzle pipeline is arranged on the nozzle rotating device, and the nozzle rotating device drives the nozzle pipeline to rotate axially, the nozzle pipeline is arranged on the nozzle pipeline, the water inlet end of the nozzle rotating joint is connected to the water outlet end of the high-pressure water pipeline of the long rod, the nozzle rotating joint is movably connected to the nozzle pipeline, and the water outlet end of the nozzle rotating joint is connected to the water inlet end of the nozzle pipeline. In this technical solution, a long rod rotating joint and a nozzle rotating joint are provided on the long rod, which are used to realize the rotation of the long rod and the rotation of the nozzle respectively. The space on the long rod is limited and many parts are integrated on the long rod. It is difficult to design a driving device on the long rod to realize the rotation of the long rod. Even if it can be realized, the parts of the rotating joint are required to be high, and the rotating joint is easy to be damaged. In addition, this technical solution can only realize the rotation of the long rod along its circumferential direction and the rotation of the nozzle along the front and rear direction of the long rod, and there is no record of the technical solution for rotating the long rod as a whole. Therefore, the structural design of this technical solution needs to be adjusted, and the cleaning effect needs to be improved. Utility Model Content
