Description

A cable retracting and releasing device for solar photovoltaic power generation Technical Field

[0001] The present invention relates to the technical field of photovoltaic cables, and in particular to a cable retracting and releasing device for solar photovoltaic power generation. Background Art

[0002] Solar energy technology will become one of the green energy technologies of the future. Solar energy or photovoltaic (PV) is increasingly being used in China. The characteristics of photovoltaic cables are determined by their special insulation and sheath materials, which we call cross-linked PE. After irradiation with an irradiation accelerator, the molecular structure of the cable material will change, thereby improving its various performances and resistance to mechanical loads. In fact, during installation and maintenance, cables can be routed on the sharp edges of roof structures. At the same time, the cables must withstand pressure, bending, tension, cross-tension loads and strong impacts. If the cable sheath strength is not enough, the cable insulation layer will be seriously damaged, which will affect the service life of the entire cable or cause problems such as short circuits, fire and personal injury.

[0003] When retracting and releasing photovoltaic cables, the retracting and releasing device needs to be adjusted due to the different outer diameters of different cables. When paying out the cables, the cables may be bent due to long-term winding and cannot be paid out straight. The surface of the cables on the ground will stick to sharp and hard objects such as sand and stones during retraction. If they are not cleaned in time, friction damage will be caused to the device and the cables during retraction. At the same time, dust will be raised when the cables are retracted and pulled, and may cover the surface of the device. When tightening, the friction mixed with dust can easily cause damage to the cable skin. Therefore, we have proposed a cable retracting and releasing device for solar photovoltaic power generation.

The inward-extending springs push the arc-shaped thorn blocks to scrape the surface of the photovoltaic cable to prevent the surface of the photovoltaic cable from sticking to mud and sand that are difficult to remove. The radius of the arc-shaped thorn blocks is adjusted by sliding the arc-shaped slider in the arc-shaped side groove to prevent the arc-shaped thorn blocks from scraping the surface of the photovoltaic cable when the size becomes larger, causing the internal wires to be exposed. At the same time, the annular brush plate cleans the photovoltaic cable to prevent the scraped mud from remaining on the photovoltaic cable.

[0009] The present invention has the beneficial effects:

[0010] 1. The present invention enables a small sliding rod to be clamped in the clamping hole so that the rounded sliding shell can resist the photovoltaic cable, thereby preventing the photovoltaic cable from loosening and falling off outwards when winding. When the winding column rotates, the surface contacts the long brush plate for cleaning, thereby preventing a large amount of dust from being mixed with the winding column, thereby preventing the photovoltaic cable from being damaged by hard friction when tightening and winding. The inner spring pushes the arc-shaped barb to scrape the surface of the photovoltaic cable, thereby preventing the surface of the photovoltaic cable from being adhered to mud and sand that are difficult to remove. The photovoltaic cable slides parallel to the side straight plate on one side of the large roller for a distance, thereby preventing the photovoltaic cable from being bent in circles when paying out due to long-term winding and tightening.

[0011] 2. The present invention sets a tightening mechanism, and the rounded sliding shell contacts the photovoltaic cable to prevent the photovoltaic cable from loosening and falling off when winding. The small sliding rod is adjusted to slide in the clamping hole to adjust the height of the rounded sliding shell to prevent the photovoltaic cable from getting larger and getting stuck between the winding post and the rounded sliding shell. At the same time, the downward pressure spring pushes the block to resist the small sliding rod to prevent the winding post from driving the small sliding rod to shake and translate during winding, resulting in incomplete contact of the rounded sliding shell. When the small sliding rod is adjusted upward, the lower top spring pushes the rounded long plate downward to contact the photovoltaic cable to prevent the rounded sliding shell from loosening and falling off when it is called back without contacting the photovoltaic cable.

[0012] 3. The present invention sets a dust removal mechanism to suck the dust near the winding post into the rectangular empty shell through the large circular hole, so as to prevent the dust from flying and covering the surface of the winding post when the photovoltaic cable is pulled. At the same time, the suction force drives the square scraper to rotate to scrape the dustproof shell, so as to prevent the surface of the dustproof shell from being covered with dust and affecting the suction efficiency. The handle is pulled down to discharge the dust, so as to prevent excessive dust from accumulating inside the rectangular empty shell for a long time and causing blockage. The handle is released and the spring is tightened to drive the long angle plate to rotate. At the same time, the small baffle resists the long angle plate to prevent the long angle plate from rotating into the rectangular empty shell and causing dust leakage.

[0013] 4. The present invention sets a cleaning mechanism, and the inner spring pushes the arc-shaped thorn block to scrape the surface of the photovoltaic cable to prevent the difficult-to-remove mud and sand from adhering to the surface of the photovoltaic cable. The arc-shaped slider slides in the arc-shaped side groove to adjust the radius of the arc-shaped thorn block to prevent the arc-shaped thorn block from scraping the surface of the photovoltaic cable when the size becomes larger, causing the internal wires to be exposed. At the same time, the annular brush plate cleans the photovoltaic cable to prevent the scraped mud from remaining on the photovoltaic cable. At the same time, the annular scraper performs a second scraping on the photovoltaic cable to prevent the mud on the surface of the photovoltaic cable from not being scraped off cleanly by the arc-shaped thorn block.

[0014] 5. The present invention sets a pay-off mechanism, and the photovoltaic cable slides parallel to a distance on the side straight plate on one side of the large roller, so as to prevent the photovoltaic cable from bending in circles due to long-term tightening during pay-off. The concave arc plate drives the small roller to move up and down, so as to prevent the large roller and the small roller from squeezing and damaging the photovoltaic cable when the size becomes larger. The gear column is rotated to clamp the gear sleeve, so as to prevent the gear sleeve from shaking and translating under the drive of the small roller after adjustment. The photovoltaic cable is passed through the tightening ring so that the tightening ring tightens the photovoltaic cable, so as to prevent the photovoltaic cable from twisting and getting stuck between the large roller and the small roller on the side straight plate during pay-off.
