A protective sleeve for photovoltaic construction cables

Abstract

This utility model discloses a protective sleeve for photovoltaic construction cables, relating to the field of photovoltaic construction technology. The protective sleeve includes a cable, an upper protective sleeve, and a lower protective sleeve. Mounting plates are fixedly installed at both ends of the cable near the lower protective sleeve. The utility model involves placing the upper and lower protective sleeves over the outside of the cable, pressing down on the upper protective sleeve, and inserting a support rod and a locking block into the mounting groove. As the locking block moves downward, it compresses the positioning rod, causing the limiting plate to slide outward. When the locking block is at the bottom of the mounting groove, it releases the positioning rod, and a spring pushes the limiting plate to reset the positioning rod. At this point, the positioning rod is at the top of the locking block, allowing the mounting plate, support rod, and locking block to be fixedly connected to the lower protective sleeve. Adjusting the two clamping mechanisms to contact the outer wall of the cable protects the cable, preventing damage to the outer layer during construction, which could lead to exposed wires and cores and safety hazards.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a protective sleeve for photovoltaic construction cables, comprising a cable 1, an upper protective sleeve 2, and a lower protective sleeve 3. Mounting plates 21 are fixedly installed at both ends of the cable 1 near the lower protective sleeve 3, and connecting plates 31 are fixedly installed at both ends of the lower protective sleeve 3 near the upper protective sleeve 2. The tops of the two mounting plates 21 contact the bottoms of the two connecting plates 31, and clamping mechanisms 4 for supporting the cable 1 are installed in the middle of the inner walls of both the upper and lower protective sleeves 2 and 3. The bottom of the mounting plates 21 is equipped with... There is a support rod 22, and a locking block 23 is fixedly connected to the bottom of the support rod 22. The top of the inner wall of the connecting plate 31 is provided with an installation groove 32. The inner wall of the connecting plate 31 and the side wall of the installation groove 32 are provided with a through groove 33 and a limiting groove 34. A positioning rod 8 is inserted into the inner wall of the through groove 33. A protrusion 11 is fixedly connected to the outer side of the positioning rod 8. A limiting plate 9 is fixedly connected to the outer wall of the positioning rod 8 and one side of the limiting groove 34. A spring 10 is fixedly connected to the side wall of the limiting plate 9 and the other side of the limiting groove 34.

[0023] The mounting plate 21 and the locking block 23 can be installed using the upper protective sleeve 2 and the lower protective sleeve 3. Since the bottom of the mounting plate 21 is equipped with a support rod 22, and the bottom of the support rod 22 is fixedly connected to the locking block 23, during photovoltaic construction, the upper protective sleeve 2 and the lower protective sleeve 3 are placed on the outside of the cable 1. Then, the upper protective sleeve 2 is pressed down, and the support rod 22 and the locking block 23 are inserted into the mounting groove 32. When the locking block 23 moves down, it squeezes the positioning rod 8, which drives the limiting plate 9 to compress the spring 10, and slides outward along the through groove 33 and the limiting groove 34. When the locking block 23 is at the bottom of the mounting groove 32, the locking block 23 releases the positioning rod 8 from its limit. Under the elastic action of the spring 10, the limiting plate 9 is pushed to reset the positioning rod 8, so that the positioning rod 8 is located at the top of the locking block 23. The mounting plate 21, the support rod 22 and the locking block 23 are fixedly connected to the lower protective sleeve 3. At this time, the two clamping mechanisms 4 are adjusted to contact the outer wall of the cable 1, thereby protecting the cable 1 and preventing the outer layer of the cable from being damaged during construction, resulting in bare wires and exposed cores, which could cause safety hazards.

[0024] See Figure 2 , Figure 4 The mounting groove 32, the through groove 33 and the limiting groove 34 are connected. The positioning rod 8 is inserted into the through groove 33 and the limiting groove 34. The inner side of the positioning rod 8 passes through the mounting groove 32. The limiting plate 9 is slidably connected to one side of the inner wall of the limiting groove 34. The limiting plate 9 is fixedly installed on the outer wall of the positioning rod 8. The inner side of the positioning rod 8 and the outer wall of the locking block 23 are both designed with inclined surfaces, and the two inclined surfaces repel each other.

[0025] The positioning rod 8, the limiting plate 9, and the spring 10 can be installed through the through groove 33 and the limiting groove 34. Since the inner side of the positioning rod 8 and the outer wall of the locking block 23 are both designed with inclined surfaces, the two inclined surfaces repel each other. When the locking block 23 is pressed down and moves down, the two inclined surfaces come into contact, which can squeeze the positioning rod 8, drive the limiting plate 9 to compress the spring 10, and slide it outward along the through groove 33 and the limiting groove 34. When the locking block 23 is at the bottom of the mounting groove 32, the locking block 23 releases the positioning rod 8. At this time, the spring 10 pushes the limiting plate 9, which drives the positioning rod 8 to reset, so that the positioning rod 8 is located at the top of the locking block 23. In this way, the mounting plate 21, the support rod 22 and the locking block 23 can be fixedly connected to the lower protective sleeve 3.

[0026] See Figure 2 , Figure 3 The inner walls of the upper protective sleeve 2 and the lower protective sleeve 3 each have two guide holes 5, and the inner walls of the upper protective sleeve 2 and the lower protective sleeve 3 each have nuts 6 installed. The clamping mechanism 4 is installed in the two guide holes 5 and the nuts 6.

[0027] The clamping mechanism 4 can be installed through the two guide holes 5 and the nut 6, thereby fixing the upper protective sleeve 2 and the lower protective sleeve 3 to the outer wall of the cable 1. After adjusting the contact between the two clamping mechanisms 4 and the outer wall of the cable 1, it can support cables 1 of different diameters, which is versatile and saves economic costs.

[0028] See Figure 2 , Figure 3 The clamping mechanism 4 includes an arc-shaped clamping plate 41, a bolt 42, and two guide posts 43. The two guide posts 43 are fixedly installed on the top of the arc-shaped clamping plate 41 and are slidably connected in the two guide holes 5. A bearing 7 is fixedly installed in the middle of the top of the arc-shaped clamping plate 41, and the bolt 42 is fixedly installed in the bearing 7. The bolt 42 is sleeved in the nut 6. The bottom of the arc-shaped clamping plate 41 has a textured design.

[0029] The bearing 7 and two guide posts 43 can be installed through the arc-shaped clamp 41. Since the bolt 42 is fixedly installed on the inner wall of the bearing 7 and the bolt 42 is sleeved in the nut 6, the upper protective sleeve 2 and the lower protective sleeve 3 are fixed to the outer wall of the cable 1. The user can rotate the bolt 42 in both directions. Under the action of the nut 6 and the bearing 7, the arc-shaped clamp 41 can drive the two guide posts 43 to move up and down along the two guide holes 5. This allows the arc-shaped clamp 41 to support cables 1 of different diameters. Since the bottom of the arc-shaped clamp 41 has a textured design, the textured design can increase the friction between the arc-shaped clamp 41 and the cable 1, prevent the cable 1 from shifting due to vibration or external force, and enhance anti-slip stability.

[0030] During operation, the mounting plate 21 and the locking block 23 can be installed using the upper protective sleeve 2 and the lower protective sleeve 3. Since a support rod 22 is installed at the bottom of the mounting plate 21, and the locking block 23 is fixedly connected to the bottom of the support rod 22, during photovoltaic construction, the upper protective sleeve 2 and the lower protective sleeve 3 are placed on the outside of the cable 1. Then, the upper protective sleeve 2 is pressed down, inserting the support rod 22 and the locking block 23 into the mounting groove 32. When the locking block 23 moves downward, it presses against the positioning rod 8, causing the limiting plate 9 to compress the spring 10, moving along the through groove 33 and the limiting groove 34 towards... When the locking block 23 is at the bottom of the mounting groove 32, it releases the positioning rod 8 from its limit. Under the elastic action of the spring 10, it pushes the limiting plate 9 to reset the positioning rod 8, so that the positioning rod 8 is at the top of the locking block 23. The mounting plate 21, the support rod 22 and the locking block 23 are fixedly connected to the lower protective sleeve 3. At this time, the two clamping mechanisms 4 are adjusted to contact the outer wall of the cable 1, thereby protecting the cable 1 and preventing the outer layer of the cable from being damaged during construction, resulting in bare wires and exposed cores, which could cause safety hazards.

[0031] The positioning rod 8, the limiting plate 9, and the spring 10 can be installed through the through groove 33 and the limiting groove 34. Since the inner side of the positioning rod 8 and the outer wall of the locking block 23 are both designed with inclined surfaces, the two inclined surfaces repel each other. When the locking block 23 is pressed down and moves down, the two inclined surfaces come into contact, which can squeeze the positioning rod 8, drive the limiting plate 9 to compress the spring 10, and slide it outward along the through groove 33 and the limiting groove 34. When the locking block 23 is at the bottom of the mounting groove 32, the locking block 23 releases the positioning rod 8. At this time, the spring 10 pushes the limiting plate 9, which drives the positioning rod 8 to reset, so that the positioning rod 8 is located at the top of the locking block 23. In this way, the mounting plate 21, the support rod 22 and the locking block 23 can be fixedly connected to the lower protective sleeve 3.

[0032] The clamping mechanism 4 can be installed through the two guide holes 5 and the nut 6, thereby fixing the upper protective sleeve 2 and the lower protective sleeve 3 to the outer wall of the cable 1. After adjusting the contact between the two clamping mechanisms 4 and the outer wall of the cable 1, it can support cables 1 of different diameters, which is versatile and saves economic costs.

[0033] The bearing 7 and two guide posts 43 can be installed through the arc-shaped clamp 41. Since the bolt 42 is fixedly installed on the inner wall of the bearing 7 and the bolt 42 is sleeved in the nut 6, the upper protective sleeve 2 and the lower protective sleeve 3 are fixed to the outer wall of the cable 1. The user can rotate the bolt 42 in both directions. Under the action of the nut 6 and the bearing 7, the arc-shaped clamp 41 can drive the two guide posts 43 to move up and down along the two guide holes 5. This allows the arc-shaped clamp 41 to support cables 1 of different diameters. Since the bottom of the arc-shaped clamp 41 has a textured design, the textured design can increase the friction between the arc-shaped clamp 41 and the cable 1, prevent the cable 1 from shifting due to vibration or external force, and enhance anti-slip stability.

[0034] In summary, this device places the upper protective sleeve 2 and the lower protective sleeve 3 on the outside of the cable 1. Pressing down the upper protective sleeve 2 allows the support rod 22 and the locking block 23 to be inserted into the mounting groove 32. As the locking block 23 moves downward, it presses the positioning rod 8, causing the limiting plate 9 to slide outward. When the locking block 23 is at the bottom of the mounting groove 32, it releases the positioning rod 8 from its limit. The spring 10 pushes the limiting plate 9, causing the positioning rod 8 to reset. At this point, the positioning rod 8 is at the top of the locking block 23, allowing the mounting plate 21, support rod 22, and locking block 23 to be fixedly connected to the lower protective sleeve 3. Adjusting the two clamping mechanisms 4 to contact the outer wall of the cable 1 protects the cable 1, preventing damage to the outer layer of the cable during construction, which could result in exposed wires and cores, posing a safety hazard.
