Description

Technical Field

[0001] The invention relates to the technical field of BWFRP electric power pipe spraying, and in particular to a glass fiber reinforced BWFRP electric power pipe spraying process. Background Art

[0002] BWFRP power pipe is a new type of pipe, which is made of fiber braiding and pultrusion. The material of this pipe is fiber and resin. The process adopted is a weaving, winding and pultrusion integrated molding process. Glass fiber and resin are selected as raw materials. Through professional equipment, the fully automated application of weaving, winding and pultrusion process is realized. It consists of 4 layers of structure including inner braided layer, longitudinal layer, circumferential layer and outer braided layer. Epoxy resin curing agent is used for surface spray curing to enhance the characteristics of glass fiber.

[0003] During the spraying process of BWFRP power pipes, the nozzle position needs to be adjusted manually to spray all sides of the BWFRP power pipes. However, this method greatly affects the spraying speed and reduces production efficiency. Manual spraying can easily lead to uneven distribution of the curing agent, affecting the curing effect.

[0004] In response to the above technical problems, the applicant has retrieved some prior arts to realize the automatic uniform and comprehensive spraying of the surface of BWFRP power pipes. For example, the patent publication number is CN218486358U. Its main technical means is to drive the spraying equipment set on the power pipeline to reciprocate in the horizontal direction through the driving box, and then cooperate with the slide to drive the two shielding covers to adjust the adaptive distance according to the diameter of the pipeline to be sprayed, so that the two shielding covers wrap the pipeline to be sprayed therein to spray the dead corners of the pipeline. After analysis by the applicant, the technical solution is The disadvantage is that during the spraying process of several ring-shaped nozzles, the paint spraying range overlaps and hits each other, which can easily cause paint to adhere to the surface of the nozzle. After long-term use, dried paint will adhere to the discharge port of the nozzle, thereby blocking part of the discharge port of the nozzle, resulting in a reduction in the discharge port area of ​​the nozzle, or even completely blocking the nozzle, making it impossible to spray a uniform protective layer on the surface of the BWFRP power pipe. Based on this, the present invention provides a glass fiber reinforced BWFRP power pipe spraying process that can automatically clean the paint adhered to the edge of the discharge port of the nozzle while spraying.

[0071] A travel switch 904 is arranged on the outer wall of the paint branch pipe 6 and its position interferes with the rotation path of the push rod 903;

[0072] The rotating ring 905 is rotatably mounted on the paint branch pipe 6, and the two are coaxially arranged. The rotating ring 905 is connected to the driving assembly 10; when the paint branch pipe 6 delivers high-pressure paint to the nozzle 4, the paint pushes the rotating rod 902 to flip, driving the push rod 903 to flip and trigger the travel switch 904, so that the driving assembly 10 is started and the rotating ring 905 is driven to rotate; and

When the BWFRP power pipe after spraying enters the curing ring 1101, it can be blown to pre-cure the paint; at the same time, the high-pressure paint transported from the paint branch pipe 6 to the nozzle 4 pushes the rotating rod 902 to flip, so that the push rod 903 flips in the opposite direction and triggers the travel switch 904. The travel switch 904 sends a signal to the external controller, and the external controller controls the opening and closing valve 1005 to open.
