[0034] Specifically, a flip cover 31 is provided above the material storage barrel 30 , and the flip cover 31 can be opened to add materials for spraying, including a mixture of glass fiber and epoxy resin, into the material storage barrel 30 .

[0035] The coating mechanism includes a protective shell 36, an air film 41 is arranged inside the protective shell 36, and the air film 41 is coated on the fiberglass boat 43 through a pneumatic component.

[0036] The coating mechanism also includes four relatively arranged cylinders 37, which are fixedly mounted on the operating table 1. The protruding ends of the cylinders 37 are fixedly connected to the protective shell 36. The protective shell 36 is provided with two symmetrically arranged pressing heads 39. A contact head 42 is provided below the pressing head 39. The contact head 42 is connected to the air cylinder 38. The air cylinder 38 is fixedly mounted on the operating table 1, and one end of the air pipe 40 is connected to the air cylinder 38, and the other end of the air pipe 40 is connected to the protective shell 36.

[0037] Working principle: Place the FRP boat 43 to be refurbished on the four clamping components, even if the inner wall of the FRP boat 43 contacts the hollow tube 15, then rotate the knob 10, and the threaded rod 11 fixedly connected to the knob 10 rotates, so that the threaded rod 11 rotates on the sliding seat 9, and the lifting rod 12 threadedly matched with the sliding seat 9 will move upward. In the process of the lifting rod 12 moving upward, the two driving rods 13 rotating and connected at both ends of the lifting rod 12 will drive the positioning blocks 14 to move away from each other, so that the two positioning blocks 14 slide out from the inside of the hollow tube 15, thereby supporting the inner wall of the FRP boat 43 through the positioning blocks 14, completing the clamping of the FRP boat 43, thereby preventing the FRP boat 43 from moving relative to the support frame 4 during the spraying, grinding and laminating process, affecting the renovation effect.

[0038] After the positioning block 14 completes the restriction of the FRP boat 43, the end of the rotating cam 17 that is not in contact with the sliding seat 9 is equivalent to a handle, and then the cam 17 rotates on the sliding seat 9, and the end of the cam 17 that contacts the crossbeam 8 presents an irregular shape. By rotating the cam 17, the protruding part of the cam 17 can contact the locking plate 16, thereby pushing the locking plate 16 upward, so that the locking plate 16 will contact the crossbeam 8, and the locking plate 16 and the crossbeam 8 will have a squeezing force. The purpose of doing this is that after the positioning and clamping of the FRP boat 43 are completed, the clamping assembly will no longer be moved as a whole. At the same time, when the relative position of the clamping assembly and the FRP boat 43 needs to be adjusted, the contact between the locking plate 16 and the crossbeam 8 can be released, and the function of the reset spring 18 is to assist the reset of the locking plate 16.

[0039] After the FRP boat 43 is fixed, the motor 5 fixedly mounted on the support frame 4 is started, so that the output shaft of the motor 5 drives the gear 6 to rotate, and the gear 6 is meshed with the rack 3, so the rotating gear 6 will move forward along the rack 3, thereby driving the support frame 4 and the FRP boat 43 on the support frame 4 to move together.

[0040] After the rack 27 moves to the bottom of the gear 20 along with the support frame 4 and the gear 20 meshes with the rack 27, the gear 20 will rotate on the stand 19 along with the movement of the rack 27, and the gear 20 drives the universal joint 22 to rotate through the belt assembly 1 21, and the universal joint 22 drives the rotating shaft 23 to rotate on the stand 19, and at the same time, the rotating shaft 23 drives the belt assembly 24 to rotate on the stand 19, and the belt assembly 24 drives the rotating rod 25 to rotate, so that the pitch angle of the nozzle 1 28 can be adjusted by the rotating block 26, so as to ensure that the glass fiber reinforced plastic boat 43 can be fully polished. The mixture of water and sand particles sprayed by the nozzle 1 28 can polish the surface of the glass fiber reinforced plastic boat 43 through friction and impact. Since the connecting block and the U-shaped frame 27 are in rotational cooperation, and the rotating block 26 and the U-shaped frame 27 are in sliding cooperation, the pitch adjustment process of the nozzle 1 28 will not be interfered. Of course, if the fiberglass boat 43 cannot meet the requirements after one grinding, the motor 5 can be made to rotate forward and reverse for multiple times, thereby completing multiple grindings until the grinding effect is achieved.

[0041] After the polishing is completed, the FRP boat 43 continues to move toward the side close to the protective shell 36. When passing under the second nozzle 33, the mixture of glass fiber and epoxy resin in the storage barrel 30 will be sprayed onto the surface of the polished FRP boat 43 through the second nozzle 33 on the discharge pipe 32, so as to increase the aesthetics of the surface of the FRP boat 43, enhance the wear resistance, corrosion resistance and UV resistance. The waste generated during spraying will flow into the collection basket 34 through the guide plate 35 and be collected by the collection basket 34.

[0042] After spraying is completed, the moving mechanism transports the FRP boat 43 to the bottom of the protective shell 36, and then starts the cylinder 37. The extended end of the cylinder 37 is contracted to move the protective shell 36 downward, and finally the air film 41 in the protective shell 36 contacts the upper surface of the FRP boat 43. At this time, the pressing head 39 on the protective shell 36 contacts the contact head 42 on the pressing head 39, and the contact signal is transmitted to the air pump, which is connected to the air cylinder 38, and then the gas is transported to the air cylinder 38. The gas enters the air pipe 40 through the air cylinder 38, and then is transported to the protective shell 36 through the air pipe 40, thereby supplying air to the air film 41, so that the air film 41 covers the surface of the FRP boat 43, and the renovation of the FRP boat 43 is completed.
