[0002] At present, large ships are huge in size, and the repair process involves painting operations, which can only be carried out in open areas. When painting the outer plates of the hull, volatile organic compounds (VOCs) are often unable to be collected and are all emitted in an unorganized manner. VOCs emissions may cause symptoms such as irritation of the eyes, nose and throat, headaches, dizziness, nausea, vomiting, and in severe cases, damage to the nervous system, respiratory system, liver and other organs. VOCs emissions are one of the main causes of the global greenhouse effect and ozone layer depletion. They also pollute air quality, accelerate the atmospheric oxidation process, lead to the formation of acid rain, and harm plant growth and ecosystems.

[0030] In one embodiment of the present invention, according to Figure 1-4 As shown, a VOCs collection and treatment device for an aerial vehicle includes an aerial vehicle 200, a standing platform 210 is provided on the aerial vehicle 200, a gas collecting hood frame 220 is provided on the standing platform 210, the gas collecting hood frame 220 forms a receiving chamber 222 and an absorption chamber 221 which are interconnected, the absorption chamber 221 is provided with an opening 223, a layer of gas collecting hood film 230 is provided on the outside of the gas collecting hood frame 220 and the standing platform 210, the opening 223 is connected to the outside, and the rest of the parts are wrapped in the gas collecting hood film 230, the receiving chamber 222 is used for human activities, and the human body sprays paint on the outer plate 120 of the ship through the opening 223; and

[0031] The collecting and processing device 300 is arranged on the standing platform 210 . The collecting and processing device 300 is connected to the absorption chamber 221 and is used to absorb and process the VOCs generated in the absorption chamber 221 during the painting process.

[0032] Specifically, the aerial vehicle 200 raises the standing platform 210 to the required painting height, and the staff sprays paint on the outer plate 120 of the ship through the opening 223. The VOCs generated by the painting are first emitted into the absorption chamber 221, and the collection and treatment device 300 absorbs and treats the generated VOCs.

[0033] Furthermore, by providing an air collecting hood frame 220 and an air collecting hood film 230, the working area is formed into a semi-closed state, and VOCs generated by spray painting will not be emitted into the atmosphere. By providing a collection and treatment device 300, the VOCs in the absorption chamber 221 can be absorbed and treated, thereby achieving the purpose of completely absorbing the volatile organic compounds generated by spray painting.

[0034] In another embodiment of the present invention, according to Figure 1 As shown, the floating dock 100 is also included; the floating dock 100 includes a bottom plate 110; a ship outer plate 120 to be painted is arranged on the bottom plate 110; a ship lifting deck 130 is also arranged between the bottom plate 110 and the ship outer plate 120, and the ship lifting deck 130 is used to support the ship outer plate 120. Specifically, the ship outer plate 120 cannot be directly placed on the floating dock 100, and the ship lifting deck 130 plays a buffering role, and the ship lifting deck 130 also plays a fixing role.

[0035] In another embodiment of the present invention, according to Figure 1-4 As shown, the collection and treatment device 300 includes a box body 310 and a fan 320 connected to the box body 310, one end of the box body 310 is connected to a hose 330, and the hose 330 is connected to the absorption chamber 221. The collection and treatment device 300 includes a box body 310 and a fan 320 connected to the box body 310, one end of the box body 310 is connected to a hose 330, and the hose 330 is connected to the absorption chamber 221. The box body 310 is sequentially arranged with a filter layer 311 and an absorption layer 312, the filter layer 311 is used to filter large particles of impurities, and the absorption layer 312 is used to absorb VOCs. An absorption port 224 is provided on the wall of the absorption chamber 221, and the hose 330 is penetrated through the absorption port 224 and extends into the absorption chamber 221. The fan 320 is arranged at the rear of the box body 310, and the front end of the box body 310 is connected to the hose 330.

[0036] Specifically, the fan 320 is located at the rear of the box 310 and is used to deliver filtered air. It is connected to the absorption chamber 221 through the hose 330. When the fan 320 is working, a negative pressure state can be formed in the absorption chamber 221 and the containing chamber 222. When VOCs are generated by spraying paint, they will be absorbed by the hose 330, filtered and absorbed by the filter layer 311 and the absorption layer 312, and discharged after being purified.

[0037] It is understandable that the filter layer 311 may be filter cotton, and the absorption layer 312 may be activated carbon. The box 310 is detachably arranged on the standing platform 210. After the activated carbon is saturated with absorption, the box 310 can be replaced to achieve the purpose of continuous absorption.

[0038] In another embodiment of the present invention, according to Figure 2-4 As shown, the standing platform 210 includes a bottom loading board 211 and a fence 212 disposed on the loading board 211, and the fence 212 is used for safety protection.
