Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic cable protective coating equipment, specifically to a photovoltaic cable weather-resistant packaging coating device. Background Technology

[0002] Photovoltaic cable weather-resistant packaging aims to protect the cable from the effects of harsh natural environments such as ultraviolet rays, high and low temperatures, humidity, and sandstorms, ensuring its long-term stable operation outdoors. Weather-resistant packaging mainly consists of an ultraviolet shielding weather-resistant protective layer, a waterproof coating, and an aging-resistant coating. Through the comprehensive application of structure, materials, and processes, photovoltaic cables can maintain stable performance and extend their service life in various harsh environments. These coatings all need to be applied using coating equipment, which mainly consists of a liquid storage tank, coating components, stirring components, and collection components. Through the coating equipment, the protective material can be evenly sprayed onto the cable surface, effectively protecting the cable from the damage caused by harsh environmental factors such as ultraviolet rays, high and low temperatures, and humidity.

[0003] According to Chinese Patent Application No. 202420898756.1, a weather-resistant packaging coating device for photovoltaic cables is disclosed, including a base plate, a support frame fixedly connected to the top of the base plate, and a high-efficiency coating component arranged above the support frame. The high-efficiency coating component includes a liquid storage tank, which is fixedly connected to the top of the support frame. A replenishment pipe is fixedly connected to the top of the liquid storage tank. An installation groove is opened on the right side of the liquid storage tank, and a pump is fixedly connected to the right side of the installation groove. An extraction pipe is fixedly connected to the left side of the extraction pump, and a discharge pipe is fixedly connected to the right side of the extraction pump. By installing the high-efficiency coating component, the coating device can simultaneously perform weather-resistant packaging coating on multiple sets of photovoltaic cables, greatly improving the efficiency of weather-resistant packaging coating on photovoltaic cables and enhancing the practicality of the coating device in use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1 to 6The image shows the first embodiment of this utility model, which provides a photovoltaic cable weather-resistant packaging coating device. This device includes a coating box 100, comprising a collection box 110 for collecting the coating material, a support frame 120 for providing coating space, and a recovery pipe 130 for discharging the coating material; a coating assembly 200, comprising a coating roller 210 for coating application and a drive assembly 220 for driving the coating roller 210; and a liquid storage assembly 300, comprising a liquid storage tank 310 fixed to the top of the support frame 120 for temporary storage, a heater 320 for providing heating, a thermocouple 330 for measuring temperature, a replenishment pipe 340 for replenishing the heat medium, a level sensor 350 for monitoring the heat medium level, and a PID controller 360 for regulating the heating temperature. The storage tank 310 includes an outer shell 311, an inner liner 312 fixed to the inner cavity of the outer shell 311, a hollow interlayer 313 located between the outer shell 311 and the inner liner 312, and a top cover 314 hinged to the top of the outer shell 311. The inner cavity of the hollow interlayer 313 is filled with a heat medium. A heater 320 is fixed to the inner cavity of the hollow interlayer 313 and located below the inner liner 312. The conveying assembly 400 includes a conveying pump 410 and a connecting pipe 420 for pumping the dressing, and a diversion pipe 430 and a branch pipe 440 for conveying the dressing to the coating roller 210. The stirring assembly 500 includes a second motor 510 and a second reducer 520 fixed to the top of the outer shell 311, and a stirring shaft 530 and a stirring blade 540 installed in the inner cavity of the inner liner 312 for stirring the dressing. The stirring blade 540 is fixed to the surface of the stirring shaft 530.

[0027] like Figures 1 to 6As shown, the mixing assembly 500 utilizes the second motor 510, the second reducer 520, the mixing shaft 530, and the mixing blades 540 to agitate the dressing. The second motor 510 drives the second reducer 520, which in turn rotates the mixing shaft 530 and the mixing blades 540, thus continuously agitating the dressing within the inner liner 312. This effectively prevents the dressing from settling or separating, maintaining a uniform state and providing favorable conditions for subsequent pumping and coating operations. Furthermore, the liquid storage assembly 300 utilizes the heater 320, thermocouple 330, liquid level sensor 350, and PID controller 360 to effectively prevent the dressing from solidifying. Two thermocouples 330 are provided to monitor the temperature of the inner liner 312 and the inner cavity of the hollow interlayer 313, respectively. The outputs of the two thermocouples 330 are connected to the PID controller. The input terminal of the controller 360 is connected to the liquid level sensor 350, which is used to monitor the liquid level of the heat medium in the hollow jacket 313. Its output terminal is also connected to the input terminal of the PID controller 360. The output terminal of the PID controller 360 is connected to the input terminal of the heater 320. When the thermocouple 330 detects a low temperature, the PID controller 360 will control the heater 320 to work according to the preset temperature value to heat the heat medium in the hollow jacket 313. Then, through heat transfer, the dressing in the inner tank 312 is heated to maintain a suitable temperature and prevent the dressing from solidifying. This ensures that the subsequent pumping and coating operations can proceed smoothly. Through the stirring and heating regulation of the stirring component 500, the problem of sedimentation, stratification, or even solidification of the effective dressing stored in the liquid storage tank 310 can be solved, ensuring the normal operation of the subsequent pumping and coating operations.

[0028] Example 2

[0029] Reference Figures 1 to 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] In this embodiment, the output shaft of the second motor 510 is connected to the input shaft of the second reducer 520, and the output shaft of the second reducer 520 passes through the inner cavity of the inner liner 312 and is connected to the stirring shaft 530.

[0031] One end of the liquid replenishment tube 340 extends into the inner cavity of the hollow interlayer 313 and is connected to the inner cavity of the hollow interlayer 313. Two thermocouples 330 are provided and are used to monitor the temperature of the inner liner 312 and the inner cavity of the hollow interlayer 313, respectively. Both thermocouples 330 are fixed to the surface of the outer shell 311, and their probe ends extend into the inner liner 312 and the inner cavity of the hollow interlayer 313, respectively.

[0032] The level sensor 350 and the PID controller 360 are both fixed on the front of the housing 311. The detection end of the level sensor 350 extends into the inner cavity of the hollow interlayer 313. The output ends of the thermocouple 330 and the level sensor 350 are both connected to the input end of the PID controller 360. The output end of the PID controller 360 is connected to the input end of the heater 320.

[0033] like Figures 1 to 4 As shown, in the liquid storage assembly 300, the dressing is stored in the inner liner 312 of the liquid storage tank 310. The hollow interlayer 313 is filled with a heat transfer medium. The heater 320 is fixed in the hollow interlayer 313 and located below the inner liner 312 to heat the heat transfer medium. The heat transfer medium can be heat transfer oil or water. There are two thermocouples 330, which monitor the temperature of the inner liner 312 and the hollow interlayer 313 respectively, and transmit the temperature signals to the PID controller 360. The liquid level sensor 350 monitors the liquid level of the heat transfer medium in the hollow interlayer 313, and its signal is also transmitted to the PID controller. The PID controller 360 adjusts the heating temperature of the heater 320 based on the signals from the thermocouple 330 and the liquid level sensor 350. When the liquid level of the heating medium is insufficient, it can be supplemented through the replenishment pipe 340. In the stirring assembly 500, the output shaft of the second motor 510 is connected to the input shaft of the second reducer 520. The output shaft of the second reducer 520 passes through the inner liner 312 and is connected to the stirring shaft 530. The stirring shaft 530 drives the stirring blade 540 to stir the dressing in the inner liner 312, thereby ensuring that the dressing is uniform.

[0034] Example 3

[0035] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0036] In this embodiment, the support frame 120 is fixed to the top of the collection box 110, one end of the recycling pipe 130 is connected to the inner cavity of the collection box 110, and the coating roller 210 is installed in the inner cavity of the support frame 120.

[0037] There are two coating rollers 210 arranged vertically. Each coating roller 210 includes a hollow roller 211, a groove 212 formed on the surface of the hollow roller 211, and a spray hole 213 formed in the inner cavity of the groove 212. The coating roller 210 is movably connected to the inner wall of the support frame 120 through a bearing.

[0038] The drive assembly 220 includes a first motor 221 and a first reducer 222 fixed to one side of the support frame 120, and a gear 223 fixed to one end of the hollow roller 211. Both hollow rollers 211 are fixed with gears 223, and the two gears 223 mesh. The output shaft of the first motor 221 is connected to the input shaft of the first reducer 222. The output shaft of the first reducer 222 passes through the inner cavity of the support frame 120 and is connected to a gear 223.

[0039] The delivery pump 410 is fixed to the top of the support frame 120. One end of the connecting pipe 420 is connected to the inner cavity of the inner liner 312, and the other end of the connecting pipe 420 is connected to the inlet of the delivery pump 410. One end of the diversion pipe 430 is connected to the outlet of the delivery pump 410. One end of the branch pipe 440 is connected to the diversion pipe 430, and the other end of the branch pipe 440 passes through the inner cavity of the support frame 120 and is connected to the inner cavity of the hollow roller 211.

[0040] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the conveying pump 410 of the conveying assembly 400 is started, drawing the dressing from the inner liner 312 through the connecting pipe 420, and conveying it through the diversion pipe 430 and the branch pipe 440 to the inner cavity of the hollow roller 211 of the coating roller 210. The first motor 221 of the drive assembly 220 drives a gear 223 to rotate through the first reducer 222. Since the two gears 223 mesh, the hollow rollers 211 of the two coating rollers 210 rotate. The dressing is sprayed from the inner cavity of the hollow roller 211 through the spray hole 213 of the groove 212 to coat the photovoltaic cable passing through the coating roller 210. During the coating process, excess dressing will drip into the collection box 110. The collected dressing can be recycled and discharged through the recycling pipe 130 for further processing or reuse.

[0041] In use, the liquid storage tank 310 of the liquid storage assembly 300 is used to store dressings, and its inner liner 312 stores dressings. The hollow interlayer 313 between the outer shell 311 and the inner liner 312 is filled with a heat medium. The heater 320 is fixed in the hollow interlayer 313 and located below the inner liner 312. The PID controller 360 controls the heater 320 to work according to the temperature of the inner liner 312 and the hollow interlayer 313 monitored by the thermocouple 330, so as to heat the heat medium and then heat the dressing in the inner liner 312. The liquid level sensor 350 monitors the liquid level of the heat medium in the hollow interlayer 313. When the liquid level is insufficient, the heat medium can be added through the liquid replenishment pipe 340. The second motor 510 of the stirring assembly 500 drives the stirring shaft 530 and the stirring blade 540 to rotate through the second reducer 520 to stir the dressing in the inner liner 312 of the liquid storage tank 310 to ensure the uniformity of the dressing.

[0042] The delivery pump 410 of the delivery assembly 400 is started, drawing the dressing from the inner liner 312 through the connecting pipe 420 and delivering it through the diversion pipe 430 and branch pipe 440 to the inner cavity of the hollow roller 211 of the coating roller 210. The first motor 221 of the drive assembly 220 drives a gear 223 to rotate through the first reducer 222. As the two gears 223 mesh, the hollow rollers 211 of the two coating rollers 210 rotate. The grooves 212 and nozzles 213 on the surface of the hollow rollers 211 of the coating rollers 210 evenly coat the photovoltaic cable passing through the inner cavity of the support frame 120 with the delivered dressing. During the coating process, excess dressing will drip into the collection box 110. The collected dressing can be recycled and discharged through the recycling pipe 130 for further processing or reuse.
