[0014] According to the above technical solution, an L-shaped plate is fixed on the left side of the connecting plate, and a short column is fixed through and fixed on the outer wall of each L-shaped plate. An arc plate is fixed at the end of each short column that is close to each other. The outer wall of the arc plate is fixedly connected to the outer wall of the ring plate.

[0015] A method for applying a spraying device for a protective coating on the outer wall of a B1-grade flame-retardant optical cable includes the following steps: S1. Pass the optical cable through the through hole in the cabinet from the left. The right end of the optical cable is connected to a traction machine. The traction machine pulls the optical cable, and the optical cable moves to the right in the through hole in the cabinet. S2. The annular groove of the ring shell rotates back and forth on the circular shaft of the ring frame, and the ring shell drives the electric nozzle to rotate back and forth. S3. The U-shaped plate drives the L-shaped rod to rotate back and forth, the L-shaped rod drives the ring plate to rotate back and forth, and the ring plate drives the sponge block to rotate back and forth.

[0016] This invention provides a spraying device for applying a protective coating to the outer wall of a B1-grade flame-retardant optical cable. It offers the following advantages: (1) The present invention uses a cabinet, a base plate, a liquid storage tank, a feed pipe, a hose, a U-shaped block, an electric telescopic rod, a U-shaped frame, a circular frame and a ring shell in conjunction with an electric nozzle. The electric telescopic rod drives the U-shaped frame to move up and down reciprocally. Under the action of the extrusion force, the electric telescopic rod rotates left and right in the U-shaped block. The U-shaped frame drives the ring shell to rotate forward and backward. The ring groove of the ring shell rotates forward and backward on the circular shaft of the circular frame. The ring shell drives the electric nozzle to rotate forward and backward. The electric nozzle rotates and sprays the protective coating onto the surface of the optical cable, preventing the protective coating from covering the surface of the optical cable unevenly and causing the spraying device to spray the protective coating poorly.

[0017] (2) The present invention uses a wiping device to make the U-shaped plate, L-shaped rod and ring plate work together with the sponge block. The U-shaped plate drives the L-shaped rod to rotate back and forth, the L-shaped rod drives the ring plate to rotate back and forth, and the ring plate drives the sponge block to rotate back and forth. During the rotation, the sponge block wipes the surface of the optical cable evenly to prevent dirt on the surface of the optical cable from causing poor coverage of the protective coating.

[0018] (3) The present invention, through the setting of the wiping device, makes the vertical ring block and the circular plate cooperate with the ring slide plate. The vertical ring block drives the circular plate to rotate back and forth, and the circular plate drives the ring slide plate to rotate back and forth. During the rotation, the circular plate blocks the protective coating from covering the sponge block, thus preventing the protective coating from covering the sponge block and causing poor wiping effect of the sponge block.

[0019] (4) The present invention, through the setting of the detection device, enables the spiral rod, connecting plate, ring plate and laser emitter to work with the photosensitive plate. The ring plate drives the laser emitter to rotate back and forth, and the ring plate drives the photosensitive plate to rotate back and forth. When the range of light sources received by the photosensitive plate is wide, it indicates that the outer surface of the optical cable is damaged. Conversely, it indicates that the outer surface of the optical cable is qualified, thus preventing the optical cable from being unqualified due to damage to the outer surface of the optical cable.

[0020] (5) The present invention, through the setting of the detection device, enables the L-shaped plate and the short column to cooperate with the arc plate. The L-shaped plate drives the short column to rotate back and forth, and the short column drives the arc plate to rotate back and forth. The ring plate supports the rotation of the arc plate, preventing the photosensitive plate from being easily damaged by vibration due to excessive amplitude when the spiral rod rotates.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Please see Figures 1-8 One embodiment of the present invention is: a spraying device for a protective coating on the outer wall of a B1-grade flame-retardant optical cable, comprising: a cabinet 1, with a through hole on each of the left and right sides of the cabinet 1, a support foot on each of the four sides of the bottom surface of the cabinet 1, a control console 101 on the upper front of the cabinet 1, a cover plate 102 hinged to the top surface of the cabinet 1, a handle on the top surface of the cover plate 102, two glass windows on the cover plate 102, a hot air blower 103 penetrating and fixed on the left side of the inner wall of the cabinet 1, the air outlet of the hot air blower 103 being located below the through hole of the cabinet 1, a cabinet door 104 on the lower front of the cabinet 1, and a base plate 2 fixed on the inner wall of the cabinet 1; A liquid storage tank 3 is located at the bottom of the cabinet 1. A pump is installed inside the liquid storage tank 3, and the pump is fixedly connected to the bottom of a hose 5. An inlet pipe 4 is located on the bottom right side of the liquid storage tank 3, passing through and fixed to the left side of the inner wall of the cabinet 1. A hose 5 is located on the top surface of the liquid storage tank 3, passing through and slidably mounted on the bottom surface of the base plate 2. A U-shaped block 6 is fixed to the top surface of the base plate 2. An electric telescopic rod 7 is hinged to the inner wall of the U-shaped block 6. A U-shaped frame 8 and a U-shaped frame 9 are fixed to the top surface of the telescopic end of the electric telescopic rod 7. 9 is fixed to the front and rear of the inner wall of the cabinet 1. The U-shaped frame 9 is located above the base plate 2. The inner wall of the U-shaped frame 9 is rotatably installed with an annular shell 10. Two round shafts are provided on the left side of the inner wall of the U-shaped frame 9. An annular groove is opened on the left and right sides of the annular shell 10. The outer wall of the round shaft of the U-shaped frame 9 is slidably connected to the inner wall of the annular groove of the annular shell 10. The outer wall of the annular shell 10 is fixedly connected to the end of the hose 5 away from the liquid storage tank 3. The bottom of the outer wall of the annular shell 10 is hinged to the inner wall of the U-shaped frame 8. Several electric nozzles 11 are fixed through and fixed to the inner wall of the annular shell 10. The electric nozzles 11 are used to spray the protective coating onto the outer wall of the optical cable. The operator passes the optical cable through the through-hole of cabinet 1 from the left. A traction machine is connected to the right end of the cable. The traction machine pulls the cable, and the operator starts it. The cable moves to the right in the through-hole of cabinet 1. Protective agent is introduced into the storage tank 3 via the feed pipe 4. The operator starts the pump in the storage tank 3 via the control panel 101. The pump draws the protective agent into the hose 5, which then delivers it to the ring shell 10. Simultaneously, the glass window of the cover plate 102 is used to observe the internal operation of cabinet 1. The operator starts the hot air blower 103, which blows hot air upwards to dry the protective coating on the surface of the optical cable. The cabinet door 104 is used to open cabinet 1, facilitating the operator's inspection and maintenance of the storage tank 3. The cabinet 1 has a supporting base plate. 2. The base plate 2 supports the U-shaped block 6. The operator starts the electric telescopic rod 7, which begins to extend and retract. The electric telescopic rod 7 drives the U-shaped frame 8 to move up and down. Under the action of the squeezing force, the electric telescopic rod 7 rotates left and right in the U-shaped block 6. The U-shaped frame 8 drives the ring shell 10 to rotate forward and backward. The annular groove of the ring shell 10 rotates forward and backward on the circular shaft of the U-shaped frame 9. The ring shell 10 drives the electric spray head 11 to rotate forward and backward. The operator starts the electric spray head 11, which rotates and sprays the protective coating onto the surface of the optical cable. This avoids the problem of uneven coverage of the protective coating on the surface of the optical cable during the spraying process, which would result in poor spraying effect of the protective coating. A wiping device 12 is provided on the left side of the ring shell 10. The wiping device 12 is used to wipe the outer surface of the optical cable. A detection device 13 is provided on the inner wall of the wiping device 12. The detection device 13 is used to detect whether there is any damage to the outer wall of the optical cable.

[0025] Working principle: The optical cable passes through the through hole of the cabinet 1 from the left. The right end of the optical cable is connected to a traction machine. The traction machine pulls the optical cable, which moves to the right in the through hole of the cabinet 1. Protective agent is introduced into the feed pipe 4 on the right side. The protective agent enters the storage tank 3. The pump of the storage tank 3 draws the protective agent into the hose 5. The hose 5 delivers the protective agent to the ring shell 10. The electric telescopic rod 7 drives the U-shaped frame 8 to move up and down reciprocally. Under the action of extrusion force, the electric telescopic rod 7 rotates left and right in the U-shaped block 6. The U-shaped frame 8 drives the ring shell 10 to rotate forward and backward. The annular groove of the ring shell 10 rotates forward and backward on the circular shaft of the circular frame 9. The ring shell 10 drives the electric nozzle 11 to rotate forward and backward. The electric nozzle 11 rotates and sprays the protective coating onto the surface of the optical cable.

[0026] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the wiping device 12 includes: a U-shaped plate 121, which is fixed to the left side of the ring shell 10; an L-shaped rod 122, which is fixed to the middle of the left side of the U-shaped plate 121; a ring plate 123 is fixed to one end of the L-shaped rod 122 that is close to each other; and a sponge block 124, which is disposed on the inner wall of the ring plate 123 and is used to wipe the surface of the optical cable. While the ring shell 10 drives the electric spray head 11 to rotate back and forth, the ring shell 10 drives the U-shaped plate 121 to rotate back and forth, the U-shaped plate 121 drives the L-shaped rod 122 to rotate back and forth, the L-shaped rod 122 drives the ring plate 123 to rotate back and forth, and the ring plate 123 drives the sponge block 124 to rotate back and forth. During the rotation, the sponge block 124 evenly wipes the surface of the optical cable, thereby avoiding the problem that the surface of the optical cable is dirty and the protective coating coverage is not good during the spraying process.

[0027] A vertical ring block 125 is fixed to one side of the U-shaped plate 121 that is close to each other. A round hole is opened in the middle of the front of each vertical ring block 125. A round plate 126 is embedded on the side of the vertical ring block 125 that is close to each other. A round hole is opened on the left side of the round plate 126. A ring slide plate 127 is fixed to the right side of the round plate 126. The ring slide plate 127 is installed through and rotatably on the left side of the U-shaped frame 9. While the U-shaped plate 121 drives the L-shaped rod 122 to rotate in both directions, the U-shaped plate 121 drives the vertical ring block 125 to rotate in both directions, the vertical ring block 125 drives the circular plate 126 to rotate in both directions, and the circular plate 126 drives the ring slide plate 127 to rotate in both directions. The ring slide plate 127 rotates in both directions within the rotating frame 9. During the rotation, the circular plate 126 prevents the protective coating from covering the sponge block 124, thus avoiding the problem of poor wiping effect of the sponge block 124 caused by the protective coating covering the sponge block 124 during the spraying process.

[0028] The detection device 13 includes: a spiral rod 131, which is fixed on the inner wall of the circular hole of the vertical ring block 125; a connecting plate 132, which is fixed on the outer wall of the spiral rod 131; a ring plate 133 is fixed on one side of the connecting plates 132 that are close to each other; a laser emitter 134, which penetrates through and is fixed on the top surface of the ring plate 133; and a photosensitive plate 135 is provided at the bottom inside the ring plate 133. The laser emitter 134 and the photosensitive plate 135 are used to detect whether there is damage on the outer surface of the optical cable. While the vertical ring block 125 drives the circular plate 126 to rotate in both directions, the vertical ring block 125 drives the loop rod 131 to rotate in both directions, the loop rod 131 drives the connecting plate 132 to rotate in both directions, the connecting plate 132 drives the ring plate 133 to rotate in both directions, the ring plate 133 drives the laser emitter 134 to rotate in both directions, and the ring plate 133 drives the photosensitive plate 135 to rotate in both directions. The operator starts the laser emitter 134, which emits infrared laser light onto the surface of the optical cable during rotation. The photosensitive plate 135 receives the infrared laser light emitted by the laser emitter 134 during rotation. When the range of light sources received by the photosensitive plate 135 is wide, it indicates that the outer surface of the optical cable is damaged; otherwise, it indicates that the outer surface of the optical cable is qualified. This avoids the problem of the optical cable being unqualified due to damage to the outer surface of the optical cable during the spraying of the protective coating.

[0029] An L-shaped plate 136 is fixed to the left side of the connecting plate 132. A short column 137 is fixed through the outer wall of the L-shaped plate 136. An arc plate 138 is fixed to the end of the short column 137 that is close to each other. The outer wall of the arc plate 138 is fixedly connected to the outer wall of the ring plate 123. While the connecting plate 132 drives the ring plate 133 to rotate in both directions, the connecting plate 132 also drives the L-shaped plate 136 to rotate in both directions. The L-shaped plate 136 drives the short column 137 to rotate in both directions, and the short column 137 drives the arc plate 138 to rotate in both directions. The ring plate 123 supports the rotation of the arc plate 138, and the L-shaped plate 136 supports the rotation of the connecting plate 132. This reduces the vibration amplitude when the spiral rod 131 rotates, thereby avoiding the problem that the photosensitive plate 135 is easily damaged by vibration when the spiral rod 131 rotates during the process of spraying the protective coating.

[0030] A method for applying a spraying device for a protective coating on the outer wall of a B1-grade flame-retardant optical cable includes the following steps: S1. Pass the optical cable through the through hole of cabinet 1 from the left. The right end of the optical cable is connected to a traction machine. The traction machine pulls the optical cable, and the optical cable moves to the right in the through hole of cabinet 1. S2. The annular groove of the ring shell 10 reciprocates on the circular shaft of the return frame 9, and the ring shell 10 drives the electric nozzle 11 to reciprocate. S3, U-shaped plate 121 drives L-shaped rod 122 to rotate in both directions, L-shaped rod 122 drives ring plate 123 to rotate in both directions, ring plate 123 drives sponge block 124 to rotate in both directions; S4, the vertical ring block 125 drives the circular plate 126 to rotate in both directions, and the circular plate 126 drives the ring slide plate 127 to rotate in both directions; S5, the ring plate 133 drives the laser emitter 134 to rotate in both directions, and the ring plate 133 drives the photosensitive plate 135 to rotate in both directions; S6, L-shaped plate 136 drives short column 137 to rotate back and forth, short column 137 drives arc plate 138 to rotate back and forth, and ring plate 123 supports the rotation of arc plate 138.
