Description

Technical Field

[0001] The invention relates to the technical field of cable spraying, in particular to a cable gun. Background Art

[0002] High-voltage cables need to be sprayed with a solution of specific materials on their outer surface. The solution is usually a liquid coating that can be cured at room temperature to increase the insulation performance, UV resistance, antifreeze performance and wear resistance of the cable.

[0003] Usually, the spray solution is applied by a spray gun, which is usually connected to an automated mechanical device and sprays in one direction. The cable is sprayed all around by rotating the cable or the spray gun. Since the cable surface is curved and the overall length is long, a large amount of solution is atomized and splashed during the spraying process due to the spraying method, resulting in waste. A cable spray gun is designed to address this problem. Summary of the invention

The liquid storage pot is fixed at the bottom of the gun body.

[0008] Preferably, one end of the conduit connected to the liquid storage pot is provided with a one-way valve allowing the spray solution to flow to the liquid storage pot, and a third pipe is provided in the liquid storage pot. The third pipe is located at the bottom of the liquid storage pot at one end, and the other end of the third pipe is connected to the first pipe. A pump body is provided on the third pipe.

[0009] Preferably, first baffles are provided on both side surfaces of the arc-shaped plate to prevent the liquid from flowing out.

[0010] Preferably, the first baffles on both sides are respectively provided with fourth pipes along the curvature direction of the arc surface, and the first baffles are also provided with multiple air holes connected to the fourth pipes. The lower ends of the fourth pipes on both sides are connected through a fifth pipe, and the fifth pipe passes through the through hole, and the air holes are perpendicular to the inner arc surface.

[0011] Preferably, the lower end of the arc-shaped plate is fixedly connected to the first baffle.

The cable gun can spray liquid paint onto the cable surface through the nozzle and nozzle by simply moving the cable gun left and right, avoiding the problem of rotating cable or rotating spray gun;

[0017] 2. When the nozzle and multiple nozzles spray the liquid coating onto the cable surface, part of the liquid coating will be sprayed onto the outside of the cable, resulting in a waste of liquid coating. The designed curved plate will block the splashed liquid coating, and the liquid coating will be collected onto the surface of the curved plate, flow into the through hole, and be collected into the liquid storage pot through the conduit, thus avoiding the problem of liquid coating waste;

[0018] 3. In order to enhance the collection effect of splashed liquid paint and atomized liquid paint, the pump body is started to collect the air in the liquid storage pot and the collected liquid paint to the first pipe for re-spraying, a low-pressure area is generated in the liquid storage pot, and the external air flows into the liquid storage pot through multiple pores and through holes. During the flow of external air, the splashed liquid paint and atomized liquid paint in the air flow into the liquid storage pot through multiple pores and through holes, thereby increasing the collection effect.
