Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic cable production, and in particular to a photovoltaic cable weather-resistant coating device. Background Technology

[0002] Photovoltaic cables are cables used for power transmission in the DC side circuit of solar photovoltaic power station systems. They are also known as solar cables. During the production process, photovoltaic cables undergo coating treatment to improve their weather resistance. This coating is typically done using methods such as the cable asphalt coating system disclosed in utility model patent CN217392840U and the cable wave-absorbing layer coating system disclosed in utility model patent CN204412555U.

[0003] However, during use, it was found that the existing coating equipment and coating process are relatively complex and costly. Furthermore, after shutdown, the material inside the pipeline is prone to solidification, which affects the normal operation of the equipment next time, resulting in poor practicality. Therefore, there is an urgent need for a photovoltaic cable weather-resistant coating device to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a photovoltaic cable weathering coating device that uses a conveying mechanism to transport photovoltaic cables, allowing the photovoltaic cables to pass through a coating mechanism and a curing mechanism. The coating mechanism applies a weather-resistant layer material to the surface of the photovoltaic cable, and the curing mechanism then cures the weather-resistant layer material on the surface of the photovoltaic cable to form a weather-resistant layer, thereby improving the practicality of the equipment.

[0005] This utility model discloses a photovoltaic cable weather-resistant coating device, which includes a conveying mechanism; it also includes a coating mechanism and a curing mechanism, both of which are mounted on the coating mechanism.

[0006] The conveying mechanism conveys the photovoltaic cable, the coating mechanism coats the photovoltaic cable, and the curing mechanism cures the weather-resistant layer coated on the photovoltaic cable.

[0007] The photovoltaic cable is conveyed by a conveying mechanism, and then passes through a coating mechanism and a curing mechanism. The coating mechanism applies a weather-resistant layer material to the surface of the photovoltaic cable, and the curing mechanism cures the weather-resistant layer material on the surface of the photovoltaic cable to form a weather-resistant layer, thereby improving the practicality of the equipment.

[0008] Preferably, the coating mechanism includes a housing, a heating kettle, a scraper, and a discharge mechanism. The heating kettle and the discharge mechanism are both installed inside the housing. A feed inlet is provided on the right side of the housing, and a discharge outlet is provided on the top of the housing. The scraper is installed on the discharge mechanism. The feed inlet of the photovoltaic cable cylinder housing is inserted, and then passes through the middle of the discharge mechanism and the scraper in sequence, before extending out from the discharge outlet of the housing. The weather-resistant layer material is poured into the heating kettle, where it is heated and melted. The molten weather-resistant layer material in the heating kettle is then discharged onto the surface of the upward-conveyed photovoltaic cable through the discharge mechanism. The scraper then evenly spreads the weather-resistant layer material on the surface of the photovoltaic cable, thereby improving the practicality of the equipment.

[0009] Preferably, the discharge mechanism includes a discharge cylinder, a piston, an electrically controlled valve one, a hydraulic cylinder one, a clinker pipe, an electrically controlled valve two, a check valve one, an air supply pipe, an electrically controlled valve three, a discharge pipe, and a check valve two. The discharge cylinder is installed in the outer shell, the piston is slidably installed in the discharge cylinder, the electrically controlled valve one is installed on the piston, the hydraulic cylinder one is fixedly installed on the discharge cylinder, and one end of the hydraulic cylinder one is installed on the piston. One end of the clinker pipe communicates with the interior of the heating kettle, and the other end of the clinker pipe communicates with the interior of the discharge cylinder. The electrically controlled valve two and the check valve one are both installed on the clinker pipe. One end of the air supply pipe communicates with the interior of the discharge cylinder, and the other end of the air supply pipe communicates with the interior of the clinker pipe. The electrically controlled valve three is installed on the air supply pipe. The discharge pipe communicates with the interior of the discharge cylinder through the check valve two, and the middle part of the discharge pipe is annular. The structure features an inner ring with multiple sets of spray holes. By opening the second electrically controlled valve, the first hydraulic cylinder contracts, causing the piston to slide upwards and drawing the molten weather-resistant material from the heating vessel into the discharge cylinder. The first hydraulic cylinder then extends, allowing the molten weather-resistant material to enter the discharge pipe. From there, the molten weather-resistant material is sprayed onto the surface of the photovoltaic cable through the spray holes on the discharge pipe. When the equipment stops, the second electrically controlled valve closes, and the air supply pipe and the first electrically controlled valve open. The first hydraulic cylinder then contracts, and the first electrically controlled valve closes again. The first hydraulic cylinder then extends, venting air into the discharge pipe and the molten material pipe. The increased air pressure in the molten material pipe and the discharge pipe forces the molten weather-resistant material out, allowing it to solidify within these pipes, thus improving the equipment's practicality.

[0010] Preferably, the curing mechanism includes a curing cylinder, a UV curing lamp, a refrigerator, and a refrigeration pipe. The curing cylinder and the refrigerator are both installed on the top of the outer casing. The UV curing lamp is installed on the inner wall of the curing cylinder. The refrigeration pipe is fitted onto the curing cylinder, and one end of the refrigeration pipe is connected to the refrigeration end of the refrigerator. The photovoltaic cable coated with molten weather-resistant material enters the curing cylinder. The low temperature reduces the fluidity of the molten weather-resistant material, and the UV curing lamp cures the weather-resistant material to form a weather-resistant layer, thereby improving the practicality of the equipment.

[0011] Preferably, the conveying mechanism includes two sets of conveying shafts, two sets of supports, two sets of drive motors, a guide shaft one, a guide shaft two, and a tensioning mechanism. The two sets of supports are respectively installed at the left and right ends of the outer casing. The two sets of conveying shafts are rotatably installed on the two sets of supports. The two sets of drive motors are respectively fixedly installed on the two sets of supports, and the output shafts of the two sets of drive motors are respectively connected to one end of the two sets of conveying shafts. The guide shaft one is installed on the top of the heating kettle, the guide shaft two is installed on the top of the curing cylinder, and the tensioning mechanism is installed on the top of the outer casing. The photovoltaic cable is wound onto the right conveying shaft, and one end of the photovoltaic cable is fixed onto the left conveying shaft. Through the operation of the two sets of drive motors, the right conveying shaft releases the photovoltaic cable, and the left conveying shaft winds up the photovoltaic cable. Guided by the guide shaft one, guide shaft two, and tensioning mechanism, the photovoltaic cable is conveyed smoothly, thereby improving the practicality of the equipment.

[0012] Preferably, the tensioning mechanism includes a second hydraulic cylinder and a support shaft. The second hydraulic cylinder is mounted on the top of the housing, and the support shaft is rotatably mounted on the second hydraulic cylinder. The photovoltaic cable is routed around the top of the support shaft, and the tension of the photovoltaic cable in the housing and curing cylinder is adjusted by extending or retracting the second hydraulic cylinder, thereby improving the practicality of the equipment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the photovoltaic cable is conveyed by the conveying mechanism, so that the photovoltaic cable passes through the coating mechanism and the curing mechanism. The coating mechanism coats the surface of the photovoltaic cable with weather-resistant material, and then the curing mechanism cures the weather-resistant material on the surface of the photovoltaic cable to form a weather-resistant layer, thereby improving the practicality of the equipment.
