Description

Technical Field

[0001] This invention relates to the field of photovoltaic cable laying technology, and in particular to a photovoltaic cable laying device. Background Technology

[0002] Photovoltaic cables are used to transmit power between solar panels and inverters, such as in solar streetlights and photovoltaic traffic lights. To facilitate later maintenance and the addition of lines, photovoltaic cables can be laid in conduits. However, due to the weight of the cables, it is time-consuming and labor-intensive to pull them manually with ropes.

[0003] Patent publication number CN217626792U discloses a photovoltaic cable laying device, including an installation platform. A first side plate is fixedly connected to the top outer wall of the installation platform near one edge. Two horizontal bars are fixedly connected to the side wall of the first side plate near the bottom. A second side plate is provided on the top of the installation platform. Two rod holes are opened on the outer wall of the second side plate near the bottom. The ends of the two horizontal bars are respectively inserted through the rod holes. Two electric telescopic rods are fixed to the top outer wall of the installation platform by bolts. The top of each electric telescopic rod is fixed to a top plate by bolts. The same support block is fixedly connected to the opposite ends of the two top plates. The end face structure of the support block is H-shaped, and the top surface of the support block is arc-shaped. The support block is placed above the two horizontal bars. A shaft hole is opened near the top position on the opposite outer wall of the first and second side plates. An end fixing mechanism is provided at the shaft hole.

[0004] The aforementioned photovoltaic cable laying device uses support blocks and two end fixing mechanisms to fix the cable roll. Then, the end of the cable is pulled out and passes through the guide tube before being laid. However, this device lacks a traction design during the cable laying process. Due to the heavy weight of the cable, manual handling is required, which is physically demanding. In some special environments where people cannot enter, ropes are usually used for traction, which is time-consuming and labor-intensive. Therefore, it is necessary to develop a photovoltaic cable laying device that is easy to pull and saves time and effort. Summary of the Invention

[0005] To overcome the shortcomings of lacking traction design in the cable laying process, which is labor-intensive to carry manually due to the weight of the cable, and which is time-consuming and labor-intensive in some special environments where people cannot enter, this invention provides a photovoltaic cable laying device that is easy to pull and saves time and labor.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] A photovoltaic cable laying device, such as Figure 1 and Figure 2 As shown, it includes a housing 1, a first rotating wheel 2, a fixing mechanism 3, and a fastening mechanism 4. There are four first rotating wheels 2, which are installed on the left and right sides of the lower part of the housing 1, symmetrically arranged front and back. The left side of the housing 1 is provided with a fixing mechanism 3, which can be used to fix the photovoltaic cable. The right side of the housing 1 is provided with a fastening mechanism 4, which can be used to make the housing 1 stick to the inner wall of the channel and drive the photovoltaic cable forward.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the fixing mechanism 3 includes a first fixing ring 31, a clamping plate 32, a rotating ring 33, a first gear 34, and a first rack 35. The first fixing ring 31 is connected to the middle left side of the outer casing 1. There are four clamping plates 32, which are evenly connected to the right side of the first fixing ring 31 along the circumference. The clamping plates 32 are made of an elastic material that is conducive to clamping the photovoltaic cable. The rotating ring 33 is threadedly connected to the outer right side of the first fixing ring 31. The first gear 34 is connected to the middle of the outer wall of the rotating ring 33. The first rack 35 is slidably connected to the left side of the inner bottom wall of the outer casing 1. The first gear 34 meshes with the first rack 35.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, the fastening mechanism 4 includes a cylinder 41, a second rack 42, a second gear 43, a third rack 44, a slide 45, a motor 46, a second rotating wheel 47, a transmission assembly 48, and a connecting rod 49. The cylinder 41 is installed on the right side of the front wall inside the outer casing 1. The second rack 42 is connected to the telescopic part behind the cylinder 41, and the rear part of the second rack 42 is slidably connected to the rear wall of the outer casing 1. The third rack 44 is slidably connected to the right side of the front wall of the outer casing 1. The second gear 43 is rotatably connected to the upper right part inside the outer casing 1, and the second gear 43 meshes with both the second rack 42 and the third rack 44. There are two slides 45, which are slidably connected between the left and right sides of the front and rear walls of the outer casing 1, respectively. The rear side of the second rack 42 is connected to the rear slide 45, and the front side of the third rack 44 is connected to the front slide 45. There are two motors 46. Motors 46 are mounted on the upper side of the middle part of the slide 45. The output shaft of each motor 46 is connected to a second wheel 47. The left and right sides of the slide 45 are also rotatably connected to two other second wheels 47. A transmission assembly 48 is connected between the upper parts of the three front second wheels 47 and another transmission assembly 48 is connected between the upper parts of the three rear second wheels 47. The transmission assembly 48 consists of three pulleys and a flat belt. The three front pulleys are connected to the upper parts of the three front second wheels 47, and a flat belt is wound around the three front pulleys. The three rear pulleys are connected to the upper parts of the three rear second wheels 47, and another flat belt is wound around the three rear pulleys. The connecting rod 49 is connected to the front part of the third rack 44, and the lower left part of the connecting rod 49 is connected to the first rack 35.

[0037] When using the device, the operator first places it inside the entrance of the laid passage, pulls out one end of the cable, passes it through the first fixing ring 31, and inserts it into the clamping plate 32. The clamping plate 32 is slightly opened by the cable. Then, the cylinder 41 is activated, controlling the telescopic part of the cylinder 41 to drive the second rack 42 to move backward, thereby driving the third rack 44 to move forward through the second gear 43, and then driving the two slides 45 to move outward. When the slides 45 drive the second rotating wheel 47 to move outward until they are flush with the inner wall of the passage, the cylinder 41 is stopped, and the third rack 44 will drive the connecting rod 49 to move forward, thereby driving the first rack 35 to move forward, and then driving the rotating ring 33 to rotate through the first gear 34. Since the rotating ring 33 is threadedly connected to the first fixing ring 31, the rotating ring 33 will move to the right at the same time. The rotating ring 33 moving to the right fits onto the clamping plate 32 and fixes the cable inside. Then, the motor 46 is activated, controlling the output shaft of the motor 46 to drive the second rotating wheel 47 in the middle to rotate, thereby driving the two slides 45 to move outward through the transmission assembly 48. The rotating second wheels 47 on both sides rotate together. The rotating second wheels 47 move the outer casing 1 to the right along the inner wall of the channel, causing the first wheel 2 to rotate. The outer casing 1 moving to the right pulls the cable towards the channel outlet. When the cable reaches the channel outlet, the motor 46 is turned off. Then, the telescopic part of the cylinder 41 is controlled to move the second rack 42 backward, thereby driving the slide 45 and the second wheel 47 to move inward and reset through the second gear 43 and the third rack 44. Then, the cylinder is turned off. The cylinder 41, and the third rack 44 will drive the connecting rod 49 to move backward, thereby driving the rotating ring 33 to rotate and move to the left to reset through the first rack 35 and the first gear 34. The rotating ring 33 is no longer on the clamping plate 32 and the cable is released. Then the device is pulled off the cable. At this time, the cable laying work is completed. In summary, the cable inside is first fixed by the rotating ring 33 on the clamping plate 32, and then the cable is pulled to the channel outlet by the second rotating wheel 47, which saves time and effort and improves laying efficiency.

[0038] Example 2

[0039] Based on Example 1, such as Figure 1 and Figure 7As shown, it also includes a cleaning mechanism 5, which can be used to clean the inner wall of the channel. The cleaning mechanism 5 includes a first fixed rod 51, a second fixed rod 52, a torsion spring 53, a rotating rod 54, and a brush 55. There are two first fixed rods 51, which are respectively connected to the second rotating wheels 47 on the right side of the front and rear parts. There are also two second fixed rods 52, which are respectively connected to the right side of the front and rear slides 45. There are two rotating rods 54, which are rotatably connected to the middle of the second fixed rods 52. A torsion spring 53 is connected between the right side of the rotating rod 54 and the second fixed rod 52. The torsion spring 53 is wound around the adjacent second fixed rod 52. A brush 55 for cleaning stains on the inner wall of the channel is connected to the side of the rotating rod 54 that is away from each other. When the first fixed rod 51 rotates with the second rotating wheel 47 on the right side, it contacts the rotating rod 54.

[0040] When the first fixed rod 51 rotates with the second rotating wheel 47 on the right until it contacts the rotating rod 54, the first fixed rod 51 abuts against the rotating rod 54, causing the brush 55 to rotate downwards. The torsion spring 53 twists. When the rotating first fixed rod 51 separates from the rotating rod 54, under the action of the torsion spring 53, the rotating rod 54 drives the brush 55 to move upwards and reset. As the first fixed rod 51 intermittently contacts and separates from the rotating rod 54, the rotating rod 54 drives the brush 55 to rotate up and down repeatedly. In summary, the brush 55, which rotates up and down repeatedly, removes the dirt from the inner wall of the channel, allowing the second rotating wheel 47 to drive the device to move along the inner wall of the channel more quickly, thus improving work efficiency.

[0041] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a limiting mechanism 6, which can be used to limit the photovoltaic cable and facilitate its sliding. The limiting mechanism 6 includes a fixed plate 61, a sliding rod 62, a first spring 63, a third rotating wheel 64, and a fourth rotating wheel 65. There are two fixed plates 61, one fixed plate 61 is connected between the front and rear sides of the upper left side of the outer casing 1, and the other fixed plate 61 is connected between the front and rear sides of the lower left side of the outer casing 1. There are also two sliding rods 62, one sliding rod 62 is slidably connected to the front of the fixed plate 61, and the other... A sliding rod 62 is slidably connected to the rear of a fixed plate 61. The upper and lower parts of the sliding rod 62 on opposite sides are connected to the adjacent fixed plate 61 by a first spring 63. The first spring 63 is wound around the adjacent fixed plate 61. There are two third rotating wheels 64, which are rotatably connected to the sliding rod 62. A fourth rotating wheel 65 is movably connected between the upper parts of the sliding rod 62, and another fourth rotating wheel 65 is movably connected between the lower parts of the sliding rod 62. The fourth rotating wheel 65 is rotatably connected to the outer casing 1.

[0042] When one end of the cable is pulled out and inserted into the clamping plate 32 through the first fixing ring 31, the cable will squeeze the third rotating wheel 64, causing it to move the sliding rod 62 outward. The first spring 63 will deform. Under the action of the first spring 63, the sliding rod 62 will drive the third rotating wheel 64 to clamp the front and rear sides of the cable. As the outer shell 1 moves to the right, it will pull the cable towards the channel outlet. The cable will drive the third rotating wheel 64 and the fourth rotating wheel 65 to rotate, reducing the friction between the cable and the outer shell 1. When the device is pulled off the cable, the cable will separate from the third rotating wheel 64. Under the elastic action of the first spring 63, the sliding rod 62 will drive the third rotating wheel 64 to move inward and reset. In summary, the cable is limited by the third rotating wheel 64 and the fourth rotating wheel 65, while reducing the friction between the cable and the outer shell 1, avoiding wear on the cable sheath, and improving the cable laying efficiency.

[0043] like Figure 1 , Figure 10 and Figure 11 As shown, it also includes a pushing mechanism 7, which can be used to push the photovoltaic cable out of the fixing mechanism 3 after it is pulled to the destination. The pushing mechanism 7 includes a magnet 71, a first wedge-shaped iron plate 72, a push plate 73 and a second spring 74. The magnet 71 is connected to the telescopic part on the rear side of the cylinder 41. The first wedge-shaped iron plate 72 is slidably connected to the right side of the front wall of the outer shell 1. The push plate 73 is slidably connected to the bottom wall of the inner wall of the outer shell 1. The second spring 74 is connected between the left side of the push plate 73 and the outer shell 1. The second spring 74 is wound around the outer shell 1. The first wedge-shaped iron plate 72 passes through the push plate 73. When the magnet 71 moves backward to contact the first wedge-shaped iron plate 72, the magnet 71 attracts the first wedge-shaped iron plate 72 under the action of magnetic force. When the first wedge-shaped iron plate 72 moves forward with the magnet 71, the first wedge-shaped iron plate 72 abuts against the push plate 73 and moves it to the left.

[0044] When the telescopic part of cylinder 41 drives the second rack 42 to move backward, it simultaneously drives magnet 71 to move backward until it contacts the first wedge-shaped iron plate 72. Under the action of magnetic force, magnet 71 attracts the first wedge-shaped iron plate 72. When the first wedge-shaped iron plate 72 moves forward with magnet 71, it abuts against push plate 73 and moves it to the left. The second spring 74 deforms, and the push plate 73, which moves to the left, pushes the cable in the clamping plate 32 to the left, making it more quickly withdrawn from the first fixing ring 31. When the first wedge-shaped iron plate 72 moves forward until it contacts the front inner wall of the outer casing 1, as magnet 71 continues to move forward, magnet 71 no longer attracts the first wedge-shaped iron plate 72. Then, under the elastic action of the second spring 74, push plate 73 moves to the right to reset, thereby driving the first wedge-shaped iron plate 72 to move backward to reset. In summary, by pushing the cable in the clamping plate 32 to the left by push plate 73, the efficiency of removing the cable from the device is improved.

[0045] like Figure 1 and Figure 12 As shown, it also includes a pushing mechanism 8, which can be used to separate the slide rod 62 to release the photovoltaic cable. The pushing mechanism 8 includes a third fixing rod 81, a second wedge plate 82, a fourth fixing rod 83, and a second fixing ring 84. There are two third fixing rods 81, which are respectively connected to the top of the slide rod 62. The fourth fixing rod 83 is connected to the upper middle part of the left inner wall of the outer casing 1. The second wedge plate 82 is slidably connected to the fourth fixing rod 83. The second fixing ring 84 is rotatably connected to the left part of the first fixing ring 31. The second fixing ring 84 is connected to the second wedge plate 82. When the second fixing ring 84 moves to the left with the first fixing ring 31, it drives the second wedge plate 82 to move to the left until it contacts the third fixing rod 81.

[0046] When the second fixing ring 84 moves to the left along with the first fixing ring 31, it causes the second wedge plate 82 to move to the left until it contacts the third fixing rod 81. The second wedge plate 82 then pushes the third fixing rod 81 outward, causing the slide rod 62 to move outward and open. The first spring 63 continues to deform, and the slide rod 62 drives the third rotating wheel 64 to no longer clamp the cable. When the second wedge plate 82 moves to the right along with the first fixing ring 31 through the second fixing ring 84 until it separates from the third fixing rod 81, under the elastic action of the first spring 63, the slide rod 62 will drive the third fixing rod 81 to move inward and reset. In summary, by pushing the third fixing rod 81 open with the second wedge plate 82, the slide rod 62 and the third rotating wheel 64 move outward and no longer clamp the cable, the convenience of removing the cable from the device is improved, thereby improving work efficiency.
