Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figures 1-5As shown, a ship painting construction equipment includes a ground mobile vehicle 1 and an aerial vehicle 2. A spraying device 3 is installed below the aerial vehicle 2. The spraying device 3 includes a front nozzle 3a, a middle rigid pipe 3b, and a rear thrust mechanism 3c. The ground mobile vehicle 1 is equipped with a main pump 4 and a paint storage tank group 5. The main pump 4 is connected to the spraying device 3 and the paint storage tank group 5 through hoses. The main pump 4 delivers paint from bottom to top, and its actual head H ≥ 25m. It draws paint from the paint storage tank group 5 and then sprays it out from the nozzle 3a.

[0025] Pump head refers to the energy gained per unit weight of liquid as it passes through the pump, used to overcome gravitational potential energy, pressure energy, and frictional losses as the water flows through pipes, valves, etc. Simply put, head is the height a pump can lift water, measured in meters (m). Head calculations are typically based on Bernoulli's equation. Actual head, also known as operating head, refers to the actual height the pump can lift water during operation.

[0026] The purpose of setting up the reverse thrust mechanism 3c is: when the nozzle 3a sprays paint forward, it will generate a backward force. Therefore, the reverse thrust mechanism 3c is set at the rear end to counteract it. Specifically, the reverse thrust mechanism 3c includes a horizontally mounted motor, and the motor shaft is connected to a propeller. The motor shaft is parallel to the central axis of the rigid tube 3b. The propeller rotates and blows air backward, which is converted into forward thrust to maintain horizontal balance.

[0027] Specifically, to improve the smoothness of paint supply, the paint storage tank group 5 includes one main liquid tank 5a and multiple auxiliary liquid tanks 5b, with at least two auxiliary liquid tanks 5b. The inlet of the main pump 4 is connected to the main liquid tank 5a. An auxiliary pump 6 is installed between the main liquid tank 5a and the auxiliary liquid tanks 5b. The auxiliary liquid tanks 5b are installed on the electric turntable 5c. The outlet pipe of the auxiliary pump 6 extends into the main liquid tank 5a. The inlet pipe of the auxiliary pump 6 is a flexible pipe, and an electric telescopic rod 7 is installed on its side. The base of the electric telescopic rod 7 is suspended and fixed, and the telescopic head is facing down and connected to the inlet pipe of the auxiliary pump 6. The auxiliary liquid tanks 5b are evenly arranged around the rotation axis of the electric turntable 5c.

[0028] Both the main liquid tank 5a and the auxiliary pump 6 are equipped with level gauges. In conjunction with the rotation of the electric turntable 5c, the auxiliary pump 6 sequentially delivers coating material from the auxiliary liquid tank 5b to the main pump 4, ensuring that the main liquid tank 5a always has sufficient coating material and preventing the main pump 4 from dry suction. The telescopic head of the electric telescopic rod 7 moves up and down with the inlet of the auxiliary pump 6. When it is necessary to switch to the next auxiliary liquid tank 5b, the electric telescopic rod 7 raises the inlet of the auxiliary liquid tank 5b, the electric turntable 5c rotates to move the next auxiliary liquid tank 5b below the inlet of the auxiliary pump 6, and the electric telescopic rod 7 then lowers the inlet of the auxiliary pump 6 to draw liquid into the tank.

[0029] Because the paint exiting the nozzle 3a is atomized into fine droplets, it will contaminate the spraying device 3 body if no shielding measures are taken, affecting the operation of the airborne aircraft 2 and the thrust reverser 3c. Therefore, a conical shield 3a-1 is set around the nozzle 3a. The conical shield 3a-1 gradually widens towards the direction of the liquid exit from the nozzle 3a. An annular groove 3a-2 is set inside the edge of the flared opening. The annular groove 3a-2 is connected to the main liquid tank 5a through the return liquid hose 3a-3. The paint sprayed on the inner wall of the conical shield 3a-1 flows back to the main liquid tank 5a through the hose 3a-3.

[0030] A multirotor aircraft, also known as a multi-axis aircraft, is an aircraft that generates lift and control torque through multiple rotating propellers (or rotors). It is capable of vertical takeoff and landing and hovering, exhibiting high maneuverability and flexibility. The aircraft 2 in this invention is one of a quadcopter, hexacopter, or octocopter. Its power system is connected to the power supply system on the ground mobile vehicle 1 via a power supply line. Therefore, the aircraft 2 itself does not need to carry batteries, which helps reduce energy consumption and extends its flight time.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any changes, modifications or additions without departing from the concept of the present utility model should fall within the protection scope of the present utility model.
