Abstract

This invention discloses a conductor preheating device for a photovoltaic cable production line, comprising a housing with a control panel mounted on its outer wall. The invention uses a conical helical spring to scrape the outer wall of the cable, thereby removing large pieces of adhering material from the cable surface. A high-pressure atomizing nozzle generates high-pressure mist to clean the floating dust on the cable surface, maintaining its cleanliness. A ring gear, via a transmission component, simultaneously drives multiple sets of scraper components to move inwards, causing them to adhere to the outer wall of the cable within the cleaning chamber. A sliding rod drives a fixed block to move inwards. At this time, two sets of connecting plates apply opposing thrusts to the two sets of sliding scrapers, causing them to move from opposite sidewalls of the scraper housing to both sides. The sliding scrapers and the scraper housing work together to cause the scraper blades to adhere to the outer wall of the cable, scraping away impurities.

Description

Technical Field

[0001] This invention relates to the field of cable production equipment technology, specifically to a conductor preheating device for a photovoltaic cable production line and a photovoltaic cable. Background Technology

[0002] With the widespread application of solar energy technology, photovoltaic cables, as a key power transmission carrier for solar power generation equipment, directly affect the performance and stability of the entire system due to their production quality. During the production of photovoltaic cables, preheating is necessary to ensure a tight seal between the sheath and the conductor. Traditional preheating devices have several shortcomings, such as the easy adhesion of impurities to the conductor surface and poor preheating effect. These problems all affect the production quality and service life of photovoltaic cables.

[0003] Before preheating, existing photovoltaic cables are easily contaminated with dust and other impurities on their outer walls due to direct contact with the external environment. These contaminants severely affect the subsequent preheating effect. More importantly, during the preheating process, the cable conductor surface may further adsorb impurity particles, which are difficult to remove effectively before and after preheating. This presents a significant challenge, especially when dealing with cables of varying thicknesses, in terms of how to efficiently remove adhering impurities from the surface of cables of different sizes. Furthermore, while some preheating devices use electric heating coils, which provide good heating results, their high power consumption leads to high operating costs. Summary of the Invention

The scraper member 612 has multiple sets of annular structures and is located in the inner cavity of the fixed base 608. The scraper member 612 is located on one side of the cable 44.

[0037] The control panel 2 is hinged to a door panel 16 located directly below the port of the housing 1. A handle 17 is provided on the outer wall of the door panel 16. An observation window 18 is provided on one side of the handle 17 and on the outer wall of the door panel 16. The observation window 18 allows observation of the pre-processing status of the cables 44 inside the housing 1. The control panel 2 is electrically connected to a drive motor 42, a fan filter 13, a heating rod 14, a high-pressure atomizing nozzle 506, a humidity sensor 507, a high-speed fan 509, an exhaust pump 505, and a servo motor 603, thereby powering the device.

[0038] The method of using the device of the present invention comprises the following steps:

[0039] Operating Step 1: When the control panel is turned on, the control panel controls the drive motor to run, which in turn drives the drive shaft to rotate the drum. The drum moves the cable laterally. At the same time, the control panel controls the heating rod to run, which preheats the cable on one side. The control panel also controls the operation of the fan filter, which generates airflow to blow on the heating rod. The device generates hot air to preheat the cable inside the preheating chamber.

[0040] Operating Step Two: When the cable moves into the cleaning chamber, the conical helical spring inside the chamber is fitted onto the cable, causing it to scrape against the outer wall of the cable, thereby removing large pieces of adhesive residue from the cable surface. Simultaneously, the control panel activates the high-pressure atomizing nozzle, which generates high-pressure mist to clean the dust from the cable surface. The conical helical spring fits snugly against the outer wall of the cable, and it can accommodate cables of different sizes.

[0041] Operating Step 3: When the cable is moved into the drying chamber, the sponge block adheres to the outer wall of the cable, blocking the moisture on the cable surface. The control panel controls the high-speed fan inside the high-speed fan to operate, blowing away the moisture on the cable surface. At the same time, the control panel controls the exhaust pump to operate, which extracts the moisture from inside the drying chamber through the air inlet housing. The high-speed fan and the exhaust pump work together to keep the cable surface dry.

[0042] Operation Step 4: The control panel controls the servo motor to run, so that the drive shaft of the servo motor drives the drive gear to run, and then the drive gear meshes and drives the ring gear to rotate. When the ring gear rotates, the ring gear drives the fixed rod to move in a circle.

[0043] Operating Step 5: When the fixed rod moves, it drives the push plate to move, which in turn causes the push plate to apply a pushing force to the sliding rod via the slide rod. The sliding rod slides inward on the inner wall of the limiting sleeve under force, which in turn pushes the scraper to move inward. The ring gear drives multiple sets of scraper to move inward through the transmission component, which in turn causes the scraper to adhere to the outer wall of the cable located in the inner cavity of the cleaning chamber, and the scraper cleans the pre-treated cable.

[0044] Operation Step Six: When the cable is large in size, when the scraper housing is attached to the surface of the cable, due to the large diameter of the cable, the multiple scraper housings cannot contact each other. Since the sliding scraper cannot be blocked by the scraper housing on one side, the sliding rod continues to move inward. The sliding rod drives the fixed block to move inward. At this time, the fixed block pushes the connecting plate to move, thereby causing the connecting plate to apply a thrust to the sliding scraper through the connecting piece.

[0045] Operating Step Seven: Since the connector has a symmetrical structure, the two sets of connecting plates apply opposing thrusts, which causes the two sets of sliding scrapers to move from the opposite side walls of the scraper housing to both sides. Scraper blades are arranged sequentially from front to back on the outer walls of the scraper housing and the sliding scraper. The scraper component has multiple annular structures located in the inner cavity of the fixed base. The sliding scraper and the scraper housing work together to drive the scraper blades to adhere to the outer wall of the cable to scrape away impurities.
