A photovoltaic cable laying device and its usage method

Abstract

The present invention relates to the technical field of cable laying, and discloses a photovoltaic cable laying device and its use method, including a pressing and conveying mechanism. The pressing and conveying mechanism further includes a machine case shell. When the motor is powered on, it drives the rotating column to rotate, and then drives the cross-shaped rotating plate and the fixed support column to rotate. When the cross-shaped rotating plate rotates, the pushing block contacts the photovoltaic cable, squeezes the photovoltaic cable, forms a clamping force with the transmission belt on the photovoltaic cable, and pushes the photovoltaic cable and the transmission belt towards the discharge port. When the fixed support column rotates, the rolling beads contact the arc-shaped convex block, and the limiting column extends outwards under the extrusion of the arc-shaped convex block and meshes with the telescopic tooth. The telescopic tooth is restricted by the limiting column and cannot contract. When rotating further, the pressure of the pushing block contacting the photovoltaic cable increases, and the increase in pressure causes the friction force to increase together, enabling the pushing block to better push the photovoltaic cable outwards, avoiding the slipping phenomenon of the pushing block when rotating to push the photovoltaic cable due to the too small force of the clamping spring during transportation.

Description

Technical Field

[0001] The present invention relates to the technical field of cable laying equipment, and specifically relates to a photovoltaic cable laying device and its usage method. Background Art

[0002] Solar photovoltaic technology converts solar radiant energy into electrical energy through a photovoltaic conversion device. The photovoltaic conversion device usually utilizes the photovoltaic effect principle of semiconductor devices for photovoltaic conversion. After being converted into electrical energy, photovoltaic cables are usually required for transmission. Photovoltaic cables are mainly used for various functions such as control installation, connection of equipment, and power transmission. They are an indispensable item in a photovoltaic power station. When transported, photovoltaic cables are usually wound around a cable reel in the shape of an I-beam wheel, and then the cable reel is transported to the construction site for laying the photovoltaic cables.

[0003] When laying photovoltaic cables, a photovoltaic cable conveyor is usually used. Among them, before using the photovoltaic cable conveyor, it is necessary to manually adjust the distance between the photovoltaic cable and the conveyor belt to make them fit tightly. This operation process is not only time-consuming and laborious, but also has low work efficiency. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a photovoltaic cable laying device, including a pressing and conveying mechanism. The pressing and conveying mechanism further includes a chassis housing. A fixed ring is fixedly connected to the side wall of the chassis housing, and a first fixed bracket is fixedly connected to the side wall of the fixed ring.

[0005] A scraping and cleaning mechanism, which includes a rotating ring rotatably connected to the inner wall of the chassis housing. A second fixed bracket is fixedly connected to the outer wall of the chassis housing, and an auxiliary wheel is rotatably connected to the outer wall of the second fixed bracket.

[0006] A rotating cleaning mechanism, which includes a third fixed bracket fixedly connected to the inner wall of the chassis housing. An arc-shaped baffle is fixedly connected to the outer wall of the third fixed bracket, and a scraping plate is fixedly connected to the inner wall of the chassis housing.

[0007] Preferably, the pressing and conveying mechanism further includes a motor fixedly connected to the inner wall of the first fixed bracket. An outlet is provided on the outer wall of the chassis housing. A rotating column is fixedly connected to the outer wall of the motor, and a fixed support column is fixedly connected to the outer wall of the rotating column. By energizing the motor to operate, the rotating column is driven to rotate. When the rotating column rotates, the fixed support column is driven to rotate, providing power support for the operation of subsequent components. The outlet is provided so that after the photovoltaic cable passes through the equipment operation, it exits from the outlet to achieve the conveying function.

[0008] Preferably, the pressing and conveying mechanism further includes a cross-shaped rotating plate fixedly connected to the outer wall of the rotating column. A clamping spring is fixedly connected to the inner wall of the cross-shaped rotating plate. One end of the outer wall of the clamping spring away from the rotating column is fixedly connected to a telescopic tooth. The outer wall of the telescopic tooth is slidably connected to the inner wall of the cross-shaped rotating plate. A pushing block is rotatably connected to the outer wall of the telescopic tooth. By the rotation of the rotating column, the cross-shaped rotating plate is synchronously driven to rotate. When the cross-shaped rotating plate rotates, the telescopic tooth and the pushing block are used to contact and squeeze the photovoltaic cable, thereby pushing the photovoltaic cable to move outward. The clamping spring is used to restore the positions of the telescopic tooth and the pushing block after the contact and extrusion.

[0009] Preferably, the pressing and conveying mechanism further includes a limiting column slidably connected to the inner wall of the fixed support column. A rolling bead is rotatably connected to the inner wall of the limiting column. A telescopic spring is fixedly connected to the outer wall of the fixed support column. One end of the outer wall of the telescopic spring away from the fixed support column is fixedly connected to the outer wall of the limiting column. An arc-shaped convex block is fixedly connected to the outer wall of the fixed ring. The outer wall of the fixed ring is slidably connected to the outer wall of the rolling bead. A rotating wheel is rotatably connected to the inner wall of the chassis housing. A transmission belt is sleeved on the outer wall of the rotating wheel. Using the characteristic that the pushing block will squeeze the photovoltaic cable when the cross-shaped rotating plate rotates, a motor is provided. When the motor is powered on and operates, it drives the rotating column to rotate. When the rotating column rotates, the cross-shaped rotating plate and the fixed support column are synchronously driven to rotate. When the cross-shaped rotating plate rotates downward, the pushing block will contact the photovoltaic cable, squeeze the photovoltaic cable downward, and form a clamping state on the photovoltaic cable with the transmission belt at the bottom. When rotating, it will push the photovoltaic cable and the transmission belt to move towards the discharge port together. When the fixed support column rotates downward, the rolling bead will contact the arc-shaped convex block. At this time, when continuing to rotate, the limiting column extends outward under the extrusion of the arc-shaped convex block and meshes with the telescopic tooth. Since the telescopic tooth is restricted by the limiting column, it cannot continue to contract inward. When continuing to rotate, the pressure of the pushing block contacting the photovoltaic cable will increase. At the same time as the pressure increases, the friction force will also increase, so that the pushing block can better push the photovoltaic cable to be conveyed outward, avoiding the phenomenon that the pushing block slips when rotating and pushing the photovoltaic cable during the conveying process due to the too small force of the clamping spring, resulting in the inability to convey the photovoltaic cable and affecting the laying efficiency of the photovoltaic cable. After the pushing block pushes the photovoltaic cable to move a certain distance, the rolling bead loses contact with the arc-shaped convex block, the limiting column contracts inward under the action of the telescopic spring, the rolling bead contacts and slides with the fixed ring. At this time, the pushing block continues to rotate upward, pops out outward under the action of the clamping spring, and resets, and then continues to rotate for conveying.

[0010] Preferably, the scraping and cleaning mechanism further includes a grooved rotating block fixedly connected to the outer wall of the rotating ring. A telescopic scraper is slidably connected to the inner wall of the grooved rotating block. A reciprocating lead screw is rotatably connected to the inner wall of the chassis housing. By using the characteristic that the grooved rotating block drives the telescopic scraper to rotate back and forth synchronously when rotating back and forth, when the photovoltaic cable passes through the middle of the rotating ring and the grooved rotating block, with the support of the auxiliary wheel and the transmission belt, the photovoltaic cables at both ends of the grooved rotating block are in a relatively horizontal position, avoiding the situation where when the outer photovoltaic cable is at a lower level, when the grooved rotating block rotates, the four telescopic scrapers are unevenly stressed, and the lower telescopic scraper is the most stressed. When scraping, it may scrape the skin of the photovoltaic cable, affecting the normal use of the photovoltaic cable. Under the action of the reciprocating lead screw, the grooved rotating block rotates alternately in the clockwise and counterclockwise directions, so that when the telescopic scraper scrapes the photovoltaic cable, it also scrapes back and forth alternately, avoiding the situation where the telescopic scraper holds the photovoltaic cable too tightly, and when the telescopic scraper scrapes continuously in one direction, it may cause the skin of the photovoltaic cable to be distorted or even damaged, resulting in the inability to be used normally, greatly affecting the laying efficiency of the photovoltaic cable and increasing the laying cost.

[0011] Preferably, the scraping and cleaning mechanism further includes a first belt sleeved on the outer wall of the reciprocating lead screw. A first belt is sleeved on the outer wall of the rotating wheel. A rack is meshed and connected to the outer wall of the grooved rotating block. A transmission block is rotatably connected to the bottom of the rack. The outer wall of the transmission block is meshed and connected to the outer wall of the reciprocating lead screw. By using the characteristic that the transmission belt and the rotating wheel rotate when transporting the photovoltaic cable, a reciprocating lead screw is provided. When the rotating wheel rotates, the reciprocating lead screw rotates together through the first belt. When the reciprocating lead screw rotates, the transmission block meshed with it will move back and forth on the upper surface of the reciprocating lead screw and drive the rack to move back and forth. When the rack moves back and forth, the grooved rotating block meshed with the rack will rotate alternately in the clockwise and counterclockwise directions. When the photovoltaic cable passes through the middle of the rotating ring and the grooved rotating block, the telescopic scraper will self-adjust according to the diameter of the photovoltaic cable to fit its surface. When the grooved rotating block rotates, the telescopic scraper will scrape back and forth on the surface of the photovoltaic cable, scraping off the soil and impurities on its surface, and when rotating back and forth, making the impurities slide out along the inner surface of the grooved rotating block, so as to achieve the effect of removing the soil and impurities on the surface of the photovoltaic cable, avoiding it from entering the equipment and affecting the normal operation of the equipment and reducing the laying efficiency of the photovoltaic cable.

[0012] Preferably, the rotating and cleaning mechanism further includes a rotating block fixedly connected to the outer wall of the cross-shaped rotating plate. The outer wall of the rotating block is rotatably connected to the inner wall of the chassis housing. The outer wall of the scraping plate is slidably connected to the outer wall of the transmission belt. A first bevel gear is rotatably connected to the inner wall of the chassis housing. The rotation of the cross-shaped rotating plate drives the rotating block to rotate. The positions of the rotating block and the first bevel gear are fixed by the chassis housing to prevent derailment and deviation during operation, affecting the normal operation of the equipment.

[0013] Preferably, the rotary cleaning mechanism further includes a second belt sleeved on the outer wall of the rotating block. A second belt is sleeved on the outer wall of the first bevel gear. A second bevel gear is meshed and connected to the outer wall of the first bevel gear. A fourth fixing bracket is fixedly connected to the outer wall of the chassis shell. The inner wall of the fourth fixing bracket is rotatably connected to the outer wall of the second bevel gear. A rotating brush is fixedly connected to the bottom of the second bevel gear. By utilizing the characteristic that the cross-shaped rotating plate continuously rotates, a rotating brush is arranged. When the cross-shaped rotating plate rotates, it drives the rotating block to rotate. Through the conduction of the second belt, when the rotating block rotates, the first bevel gear also rotates synchronously. When the first bevel gear rotates, through the second bevel gear, the rotating brush also rotates together. When the cross-shaped rotating plate rotates, the pushing block contacts the rotating brush. Under the rotation of the rotating brush, the impurities on the surface of the pushing block are removed. At the same time, during the rotation of the rotating brush, due to the effect of the eccentricity, the impurities are thrown outwards onto the arc-shaped baffle and then fall down onto the conveyor belt. When the conveyor belt moves, it contacts the scraping plate again, so that the impurities falling onto the conveyor belt are scraped off by the scraping plate and then discharged outside the device, avoiding the situation that when the telescopic scraper scrapes the photovoltaic cable, due to the unevenness on the surface of the photovoltaic cable, some impurities will remain. When the pushing block pushes the photovoltaic cable, due to the relatively large clamping force, the impurities adhere to the surface of the pushing block. When there are more impurities adhering to the surface of the pushing block, it may cause the pushing block to slip when pushing the photovoltaic cable, thereby affecting the conveying effect of the photovoltaic cable.

[0014] A usage method of a photovoltaic cable laying device includes the following steps:

[0015] S1: When the motor is powered on and running, it drives the rotating column to rotate. When the rotating column rotates, it drives the cross-shaped rotating plate and the fixed support column to rotate. When the cross-shaped rotating plate rotates downward, the pushing block contacts the photovoltaic cable, squeezes the photovoltaic cable, and forms a clamping state on the photovoltaic cable with the conveyor belt. When rotating, it pushes the photovoltaic cable and the conveyor belt towards the discharge port.

[0016] S2: When the fixed support column rotates downward, the rolling beads will contact the arc-shaped convex block. At this time, when continuing to rotate, the limiting column is extruded by the arc-shaped convex block and extends outwards and meshes with the telescopic tooth.

[0017] S3: Since the telescopic tooth is restricted by the limiting column and cannot continue to contract inward, when continuing to rotate, the pressure of the pushing block contacting the photovoltaic cable will increase. At the same time when the pressure increases, the friction force will also increase, so that the pushing block can better push the photovoltaic cable to be conveyed outwards.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention utilizes the characteristic that when the cross-shaped rotating plate rotates, the pushing block will squeeze the photovoltaic cable. A motor is provided. When the motor is powered on and running, it drives the rotating column to rotate. When the rotating column rotates, it synchronously drives the cross-shaped rotating plate and the fixed support column to rotate. When the cross-shaped rotating plate rotates downward, the pushing block will contact the photovoltaic cable, squeeze the photovoltaic cable downward, and form a clamping state for the photovoltaic cable with the conveyor belt at the bottom. When rotating, it will push the photovoltaic cable and the conveyor belt to move towards the discharge port together. When the fixed support column rotates downward, the rolling beads will contact the arc-shaped convex block. At this time, when continuing to rotate, the limiting column will extend outward under the extrusion of the arc-shaped convex block and engage with the telescopic tooth. Since the telescopic tooth is restricted by the limiting column, it will no longer be able to contract inward. When continuing to rotate, the pressure of the pushing block contacting the photovoltaic cable will increase, and at the same time, the friction force will also increase, so that the pushing block can better push the photovoltaic cable to be conveyed outward, avoiding the phenomenon that the pushing block slips when rotating and pushing the photovoltaic cable due to the too small force of the clamping spring during the conveying process, resulting in the inability to convey the photovoltaic cable and affecting the laying efficiency of the photovoltaic cable. After the pushing block pushes the photovoltaic cable to move a certain distance, the rolling beads lose contact with the arc-shaped convex block, the limiting column contracts inward under the action of the telescopic spring, the rolling beads contact and slide with the fixed ring. At this time, when the pushing block continues to rotate upward, it pops out outward under the action of the clamping spring and resets, and then continues to rotate for conveying.

[0020] (2) The present invention utilizes the characteristic that when conveying the photovoltaic cable, the conveyor belt and the rotating wheel will rotate. A reciprocating lead screw is provided. When the rotating wheel rotates, the reciprocating lead screw rotates together through the first belt. When the reciprocating lead screw rotates, the transmission block engaged with it will move back and forth on the upper surface of the reciprocating lead screw and drive the rack to move back and forth. When the rack moves back and forth, the grooved rotating block engaged with the rack will rotate alternately in the clockwise and counterclockwise directions. When the photovoltaic cable passes through the middle of the rotating ring and the grooved rotating block, the telescopic scraper will self-adjust according to the diameter of the photovoltaic cable to fit its surface. When the grooved rotating block rotates, the telescopic scraper will scrape back and forth on the surface of the photovoltaic cable, scrape off the soil and impurities on its surface, and when rotating back and forth, make the impurities slide outward along the inner surface of the grooved rotating block, so as to achieve the effect of removing the soil and impurities on the surface of the photovoltaic cable, avoiding it from entering the equipment and affecting the normal operation of the equipment and reducing the laying efficiency of the photovoltaic cable.

[0021] (3) When the grooved rotating block rotates back and forth in the present invention, it drives the telescopic scraper to rotate back and forth synchronously. When the photovoltaic cable passes through the middle of the rotating ring and the grooved rotating block, with the support of the auxiliary wheel and the transmission belt, the photovoltaic cables at both ends of the grooved rotating block are in a relatively horizontal position, avoiding the situation that when the outer photovoltaic cable is at a lower position, the four telescopic scrapers are unevenly stressed when the grooved rotating block rotates, and the lower telescopic scraper is the most stressed. When scraping, it may scrape the skin of the photovoltaic cable, affecting the normal use of the photovoltaic cable. Under the action of the reciprocating screw rod, the grooved rotating block rotates alternately in the clockwise and counterclockwise directions, so that when the telescopic scraper scrapes the photovoltaic cable, it also scrapes back and forth alternately, avoiding the situation that due to the telescopic scraper clamping the photovoltaic cable too tightly, when the telescopic scraper scrapes in a continuous direction, it may cause the skin of the photovoltaic cable to be distorted or even damaged, thus unable to be used normally, greatly affecting the laying efficiency of the photovoltaic cable and increasing the laying cost.

[0022] (4) When the cross-shaped rotating plate rotates continuously in the present invention, a rotating brush is provided. When the cross-shaped rotating plate rotates, it drives the rotating block to rotate. Through the conduction of the second belt, when the rotating block rotates, the first bevel gear also rotates synchronously. When the first bevel gear rotates, through the second bevel gear, the rotating brush also rotates together. When the cross-shaped rotating plate rotates, the pushing block contacts the rotating brush. Under the rotation of the rotating brush, the impurities on the surface of the pushing block are removed. At the same time, during the rotation of the rotating brush, due to the action of the eccentricity, the impurities are thrown outwards onto the arc-shaped baffle and then fall down onto the transmission belt. When the transmission belt moves, it contacts the scraping plate again, so that the impurities falling onto the transmission belt are scraped off by the scraping plate and then discharged outside the equipment, avoiding the situation that when the telescopic scraper scrapes the photovoltaic cable, due to the unevenness on the surface of the photovoltaic cable, some impurities will remain, and when the pushing block pushes the photovoltaic cable, due to the relatively large clamping force, the impurities adhere to the surface of the pushing block. When there are more impurities adhering to the surface of the pushing block, it may cause the pushing block to slip when pushing the photovoltaic cable, thus affecting the conveying effect of the photovoltaic cable.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Example 1. Please refer to Figure 1 - Figure 4 , the present invention is a photovoltaic cable laying device, including a pressing and conveying mechanism 1. The pressing and conveying mechanism 1 further includes a chassis housing 101. A fixing ring 102 is fixedly connected to the side wall of the chassis housing 101, and a first fixing bracket 103 is fixedly connected to the side wall of the fixing ring 102;

[0037] A scraping and cleaning mechanism 2. The scraping and cleaning mechanism 2 includes a rotating ring 201 rotatably connected to the inner wall of the chassis housing 101. A second fixing bracket 202 is fixedly connected to the outer wall of the chassis housing 101, and an auxiliary wheel 203 is rotatably connected to the outer wall of the second fixing bracket 202;

[0038] A rotating cleaning mechanism 3. The rotating cleaning mechanism 3 includes a third fixing bracket 301 fixedly connected to the inner wall of the chassis housing 101. An arc-shaped baffle 302 is fixedly connected to the outer wall of the third fixing bracket 301, and a scraping plate 303 is fixedly connected to the inner wall of the chassis housing 101.

[0039] The pressing and conveying mechanism 1 further includes a motor 104 fixedly connected to the inner wall of the first fixing bracket 103. An outlet 105 is provided on the outer wall of the chassis housing 101. A rotating column 106 is fixedly connected to the outer wall of the motor 104, and a fixing pillar 107 is fixedly connected to the outer wall of the rotating column 106. By energizing and operating the motor 104, the rotating column 106 is driven to rotate. When the rotating column 106 rotates, the fixing pillar 107 is driven to rotate, providing power support for the operation of subsequent components. The outlet 105 is provided, and after the photovoltaic cable passes through the equipment operation, it exits from the outlet 105 to achieve the conveying function.

[0040] The pressing and conveying mechanism 1 further includes a cross-shaped rotating plate 108 fixedly connected to the outer wall of the rotating column 106. A clamping spring 109 is fixedly connected to the inner wall of the cross-shaped rotating plate 108. One end of the outer wall of the clamping spring 109 far from the rotating column 106 is fixedly connected to a telescopic tooth 110. The outer wall of the telescopic tooth 110 is slidably connected to the inner wall of the cross-shaped rotating plate 108. A pushing block 111 is rotatably connected to the outer wall of the telescopic tooth 110. By the rotation of the rotating column 106, the cross-shaped rotating plate 108 is synchronously driven to rotate. When the cross-shaped rotating plate 108 rotates, the telescopic tooth 110 and the pushing block 111 are used to contact and squeeze the photovoltaic cable, thereby pushing the photovoltaic cable to move outward. The clamping spring 109 is used to restore the positions of the telescopic tooth 110 and the pushing block 111 after the contact extrusion.

[0041] The pressing and conveying mechanism 1 further includes a limiting column 112 slidably connected to the inner wall of the fixed support column 107. A rolling bead 113 is rotatably connected to the inner wall of the limiting column 112. An expansion spring 114 is fixedly connected to the outer wall of the fixed support column 107. One end of the outer wall of the expansion spring 114 away from the fixed support column 107 is fixedly connected to the outer wall of the limiting column 112. An arc-shaped convex block 115 is fixedly connected to the outer wall of the fixed ring 102. The outer wall of the fixed ring 102 is slidably connected to the outer wall of the rolling bead 113. A rotating wheel 116 is rotatably connected to the inner wall of the chassis housing 101. A transmission belt 117 is sleeved on the outer wall of the rotating wheel 116. By utilizing the characteristic that when the cross-shaped rotating plate 108 rotates, the pushing block 111 will squeeze the photovoltaic cable, a motor 104 is provided. When the motor 104 is powered on and operates, it drives the rotating column 106 to rotate. When the rotating column 106 rotates, it synchronously drives the cross-shaped rotating plate 108 and the fixed support column 107 to rotate. When the cross-shaped rotating plate 108 rotates downward, the pushing block 111 will contact the photovoltaic cable, squeeze the photovoltaic cable downward, and form a clamping state for the photovoltaic cable with the transmission belt 117 at the bottom. When rotating, it will push the photovoltaic cable and the transmission belt 117 to move together towards the discharge port 105. When the fixed support column 107 rotates downward, the rolling bead 113 will contact the arc-shaped convex block 115. At this time, when continuing to rotate, the limiting column 112 extends outward under the extrusion of the arc-shaped convex block 115 and meshes with the telescopic tooth 110. Since the telescopic tooth 110 is restricted by the limiting column 112, it cannot continue to contract inward. When continuing to rotate, the pressure of the pushing block 111 contacting the photovoltaic cable will increase. At the same time as the pressure increases, the friction force will also increase, so that the pushing block 111 can better push the photovoltaic cable to be conveyed outward, avoiding the phenomenon that the pushing block 111 slips when rotating and pushing the photovoltaic cable due to the too small force of the clamping spring 109 during the conveying process, resulting in the inability to convey the photovoltaic cable and affecting the laying efficiency of the photovoltaic cable. After the pushing block 111 pushes the photovoltaic cable to move a certain distance, the rolling bead 113 loses contact with the arc-shaped convex block 115. The limiting column 112 contracts inward under the action of the expansion spring 114. The rolling bead 113 contacts and slides with the fixed ring 102. At this time, the pushing block 111 continues to rotate and rise, pops out outward under the action of the clamping spring 109, resets, and then continues to rotate for conveying.

[0042] Embodiment 2. Please refer to Figure 5 - Figure 9, the present invention is a photovoltaic cable laying device. On the basis of Embodiment 1, the scraping and cleaning mechanism 2 further includes a grooved rotating block 204 fixedly connected to the outer wall of the rotating ring 201. A telescopic scraper 205 is slidably connected to the inner wall of the grooved rotating block 204. A reciprocating lead screw 206 is rotatably connected to the inner wall of the chassis housing 101. By utilizing the characteristic that when the grooved rotating block 204 rotates back and forth, it drives the telescopic scraper 205 to rotate back and forth synchronously. When the photovoltaic cable passes through the middle of the rotating ring 201 and the grooved rotating block 204, with the support of the auxiliary wheel 203 and the transmission belt 117, the photovoltaic cables at both ends of the grooved rotating block 204 are in a relatively horizontal position, avoiding the situation where when the outer photovoltaic cable is at a lower level, when the grooved rotating block 204 rotates, the four telescopic scrapers 205 are unevenly stressed, and the lower telescopic scraper 205 is the most stressed. When scraping, it may scrape the skin of the photovoltaic cable, affecting the normal use of the photovoltaic cable. Under the action of the reciprocating lead screw 206, the grooved rotating block 204 rotates alternately in the clockwise and counterclockwise directions, so that when the telescopic scraper 205 scrapes the photovoltaic cable, it also scrapes back and forth alternately, avoiding the situation where due to the telescopic scraper 205 clamping the photovoltaic cable too tightly, when the telescopic scraper 205 scrapes continuously in one direction, it may cause the skin of the photovoltaic cable to be distorted or even damaged, thus unable to be used normally, greatly affecting the efficiency of laying the photovoltaic cable and increasing the laying cost.

[0043] The scraping and cleaning mechanism 2 further includes a belt 207 sleeved on the outer wall of the reciprocating lead screw 206. A belt 207 is sleeved on the outer wall of the rotating wheel 116. A rack 208 is meshed and connected to the outer wall of the grooved rotating block 204. The bottom of the rack 208 is rotatably connected to a transmission block 209. The outer wall of the transmission block 209 is meshed and connected to the outer wall of the reciprocating lead screw 206. By utilizing the characteristic that when transporting the photovoltaic cable, the transmission belt 117 and the rotating wheel 116 will rotate, a reciprocating lead screw 206 is set. When the rotating wheel 116 rotates, the reciprocating lead screw 206 rotates together through the belt 207. When the reciprocating lead screw 206 rotates, the transmission block 209 meshed with it will move back and forth on the upper surface of the reciprocating lead screw 206 and drive the rack 208 to move back and forth together. When the rack 208 moves back and forth, it will cause the grooved rotating block 204 meshed with the rack 208 to rotate alternately in the clockwise and counterclockwise directions. When the photovoltaic cable passes through the middle of the rotating ring 201 and the grooved rotating block 204, the telescopic scraper 205 will self-adjust according to the diameter of the photovoltaic cable to fit its surface. When the grooved rotating block 204 rotates, the telescopic scraper 205 will scrape back and forth on the surface of the photovoltaic cable, scraping off the soil impurities on its surface, and when rotating back and forth, the impurities will slide out along the inner surface of the grooved rotating block 204, so as to achieve the effect of removing the soil impurities on the surface of the photovoltaic cable, avoiding them from entering the equipment and affecting the normal operation of the equipment and reducing the efficiency of laying the photovoltaic cable.

[0044] The rotating cleaning mechanism 3 also includes a rotating block 304 fixedly connected to the outer wall of the cross rotating plate 108, the outer wall of the rotating block 304 is rotatably connected to the inner wall of the chassis shell 101, the outer wall of the scraper plate 303 is slidably connected to the outer wall of the transmission belt 117, and the inner wall of the chassis shell 101 is rotatably connected with a bevel gear 1 305, and the rotating block 304 is driven to rotate by the rotation of the cross rotating plate 108. The positions of the rotating block 304 and the bevel gear 1 305 are fixed by the chassis shell 101 to prevent derailment and deviation during operation, which will affect the normal operation of the equipment.

[0045] The rotary cleaning mechanism 3 also includes a belt 2 306 sleeved on the outer wall of the rotating block 304, a belt 2 306 sleeved on the outer wall of the bevel gear 1 305, a bevel gear 2 307 meshingly connected to the outer wall of the bevel gear 1 305, a fixed bracket 4 308 fixedly connected to the outer wall of the chassis shell 101, the inner wall of the fixed bracket 4 308 is rotatably connected to the outer wall of the bevel gear 2 307, and a rotating brush 309 is fixedly connected to the bottom of the bevel gear 2 307. Utilizing the characteristic of continuous rotation of the cross rotating plate 108, a rotating brush 309 is provided. When the cross rotating plate 108 rotates, the rotating block 304 is driven to rotate. Through the transmission of the belt 2 306, when the rotating block 304 rotates, the bevel gear 1 305 also rotates synchronously. When the bevel gear 1 305 rotates, the rotating brush 309 also rotates together through the bevel gear 2 307. When the cross rotating plate 108 rotates, the push brush 309 The movable block 111 contacts the rotating brush 309, and the rotating brush 309 rotates to remove impurities on the surface of the pushing block 111. At the same time, during the rotation of the rotating brush 309, the impurities are thrown outward onto the arc baffle 302 through the effect of eccentricity, and then fall downward onto the transmission belt 117. When the transmission belt 117 moves, it contacts the scraper plate 303, so that the impurities falling on the transmission belt 117 are scraped off by the scraper plate 303, and then discharged to the outside of the equipment, so as to avoid that when the telescopic scraper 205 scrapes the photovoltaic cable, some impurities will remain due to the unevenness on the surface of the photovoltaic cable, so that when the pushing block 111 pushes the photovoltaic cable, due to the large clamping force, the impurities are adhered to the surface of the pushing block 111. When there are many impurities adhering to the surface of the pushing block 111, the pushing block 111 may slip when pushing the photovoltaic cable, thereby affecting the conveying effect of the photovoltaic cable.

[0046] The method for using the photovoltaic cable laying device includes the following steps:

[0047] S1: When the motor 104 is powered on and running, it drives the rotating column 106 to rotate. When the rotating column 106 rotates, it drives the cross-shaped rotating plate 108 and the fixed support column 107 to rotate. When the cross-shaped rotating plate 108 rotates downward, it makes the pushing block 111 contact the photovoltaic cable, squeezes the photovoltaic cable, and forms a clamping state on the photovoltaic cable with the transmission belt 117. When rotating, it pushes the photovoltaic cable and the transmission belt 117 towards the discharge port 105;

[0048] S2: When the fixed support column 107 rotates downward, the rolling beads 113 will contact the arc-shaped convex block 115. At this time, when continuing to rotate, the limit column 112 is extruded by the arc-shaped convex block 115 and extends outwards to engage with the telescopic tooth 110;

[0049] S3: Since the telescopic tooth 110 is restricted by the limit column 112 and cannot continue to contract inward, when continuing to rotate, the pressure of the pushing block 111 contacting the photovoltaic cable will increase. At the same time as the pressure increases, the friction force will also increase, so that the pushing block 111 can better push the photovoltaic cable outwards.

[0050] A specific application of this embodiment is: when using this device, install this device at the required position and connect the power supply of the motor 104. When the motor 104 is powered on and running, it drives the rotating column 106 to rotate. When the rotating column 106 rotates, it synchronously drives the cross-shaped rotating plate 108 and the fixed support column 107 to rotate. When the cross-shaped rotating plate 108 rotates downward, it will make the pushing block 111 contact the photovoltaic cable, squeeze the photovoltaic cable downward, and form a clamping state on the photovoltaic cable with the transmission belt 117 at the bottom. When rotating, it will push the photovoltaic cable and the transmission belt 117 together towards the discharge port 105. When the fixed support column 107 rotates downward, the rolling beads 113 will contact the arc-shaped convex block 115. At this time, when continuing to rotate, the limit column 112 is extruded by the arc-shaped convex block 115 and extends outwards to engage with the telescopic tooth 110. Since the telescopic tooth 110 is restricted by the limit column 112 and cannot continue to contract inward, when continuing to rotate, the pressure of the pushing block 111 contacting the photovoltaic cable will increase. At the same time as the pressure increases, the friction force will also increase, so that the pushing block 111 can better push the photovoltaic cable outwards, avoiding the phenomenon that the pushing block 111 slips when rotating and pushing the photovoltaic cable during the conveying process due to the too small force of the clamping spring 109, resulting in the inability to convey the photovoltaic cable and affecting the laying efficiency of the photovoltaic cable. After the pushing block 111 pushes the photovoltaic cable to move a certain distance, the rolling beads 113 lose contact with the arc-shaped convex block 115, and the limit column 112 contracts inward under the action of the telescopic spring 114. The rolling beads 113 contact and slide with the fixed ring 102. At this time, the pushing block 111 rotates upward again, pops outwards under the action of the clamping spring 109, resets, and then continues to rotate for conveying.

[0051] Taking advantage of the characteristics that when transporting the photovoltaic cable, the conveyor belt 117 and the rotating wheel 116 will rotate, a reciprocating lead screw 206 is set. When the rotating wheel 116 rotates, the reciprocating lead screw 206 rotates together through the first belt 207. When the reciprocating lead screw 206 rotates, the transmission block 209 engaged with it will move back and forth on the upper surface of the reciprocating lead screw 206 and drive the rack 208 to move back and forth. When the rack 208 moves back and forth, it will cause the grooved rotating block 204 engaged with the rack 208 to rotate alternately in the clockwise and counterclockwise directions. When the photovoltaic cable passes through the middle of the rotating ring 201 and the grooved rotating block 204, the telescopic scraper 205 will self-adjust according to the diameter of the photovoltaic cable to make it fit the surface of the cable. When the grooved rotating block 204 rotates, the telescopic scraper 205 will scrape back and forth on the surface of the photovoltaic cable to scrape off the soil and impurities on its surface. When rotating back and forth, the impurities will slide out along the inner surface of the grooved rotating block 204, so as to achieve the effect of removing the soil and impurities on the surface of the photovoltaic cable, prevent them from entering the equipment, affect the normal operation of the equipment, and reduce the laying efficiency of the photovoltaic cable. When the photovoltaic cable passes through the middle of the rotating ring 201 and the grooved rotating block 204, through the support of the auxiliary wheel 203 and the conveyor belt 117, the photovoltaic cables at both ends of the grooved rotating block 204 are in a relatively horizontal position, preventing the outer photovoltaic cable from being in a lower position, which may cause uneven forces on the four telescopic scrapers 205 when the grooved rotating block 204 rotates. The lower telescopic scraper 205 bears the greatest force and may scrape the skin of the photovoltaic cable during scraping, affecting the normal use of the photovoltaic cable. Under the action of the reciprocating lead screw 206, during the alternating rotation of the grooved rotating block 204 in the clockwise and counterclockwise directions, when the telescopic scraper 205 scrapes the photovoltaic cable, it also scrapes back and forth alternately, preventing the telescopic scraper 205 from clamping the photovoltaic cable too tightly. When the telescopic scraper 205 scrapes continuously in one direction, it may cause the skin of the photovoltaic cable to be distorted or even damaged, so that it cannot be used normally, greatly affecting the laying efficiency of the photovoltaic cable and increasing the laying cost.

[0052] Taking advantage of the continuous rotation of the cross rotating plate 108, a rotating brush 309 is provided. When the cross rotating plate 108 rotates, the rotating block 304 is driven to rotate. Through the transmission of the second belt 306, when the rotating block 304 rotates, the bevel gear 1 305 also rotates synchronously. When the bevel gear 1 305 rotates, the rotating brush 309 is also rotated through the bevel gear 2 307. When the cross rotating plate 108 rotates, the push block 111 is brought into contact with the rotating brush 309. Under the rotation of the rotating brush 309, impurities on the surface of the push block 111 are removed. At the same time, during the rotation of the rotating brush 309, the impurities are thrown outwards through the effect of eccentricity. The impurities on the transmission belt 117 are scraped off by the scraper plate 303 and discharged out of the equipment to avoid the impurities remaining on the surface of the photovoltaic cable due to the unevenness of the photovoltaic cable when the telescopic scraper 205 is scraping the photovoltaic cable. When the pushing block 111 pushes the photovoltaic cable, the impurities are adhered to the surface of the pushing block 111 due to the large clamping force. When there are many impurities adhered on the surface of the pushing block 111, the pushing block 111 may slip when pushing the photovoltaic cable, thereby affecting the conveying effect of the photovoltaic cable.

When the rotating column (106) rotates, the cross rotating plate (108) and the fixed support column (107) are driven to rotate.
