[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Example

[0043] A photovoltaic cable repair process comprises the following steps:

[0044] S1. Remove the soil on the surface of the photovoltaic cable to expose the damaged part of the photovoltaic cable 6;

[0045] S2. Move the fixed lifting assembly to directly above the photovoltaic cable 6, and ensure that the center line of the fixed lifting assembly and the axis of the photovoltaic cable 6 are on the same vertical plane;

[0046] S3, the photovoltaic cable repair device works and clamps the photovoltaic cable, and lifts the photovoltaic cable 6 upward until the axis of the photovoltaic cable 6 and the center line of the cleaning component are in the same horizontal plane;

[0047] S4, the cleaning component cleans the surface of the photovoltaic cable 6 to make the surface of the photovoltaic cable 6 clean and dust-free;

[0048] S5. Lift the photovoltaic cable 6 by fixing the lifting assembly until the axis of the photovoltaic cable 6 and the repair assembly 7 are on the same horizontal plane;

[0049] S5. Repair the damaged portion of the photovoltaic cable 6 using the repair tape in the repair component 7 and the repair glue in the coating component 8. The repair method is to wrap a layer of repair tape and then apply a layer of repair glue, and repeat this process three times.

[0050] S6. Fill a layer of bentonite at the original location of the photovoltaic cable 6;

[0051] S7, moving the photovoltaic cable 6 downward by fixing the lifting assembly and placing it on the bentonite;

[0052] S8, moving the fixed lifting assembly so that it is no longer above the photovoltaic cable 6;

[0053] S9, filling a layer of bentonite on the outer side of the photovoltaic cable 6 to wrap the damaged part of the photovoltaic cable 6;

[0054] S10: Refill the soil above the photovoltaic cable 6 and compact it.

[0055] In this embodiment, diatomaceous earth is added to the bentonite, and the content of diatomaceous earth in the bentonite is 10%-20%.

[0056] In this embodiment, the above process is used to achieve rapid repair of the photovoltaic cable 6. Since the photovoltaic cable 6 reserves a certain length for deformation during laying and the photovoltaic cable 6 has a certain elasticity, the photovoltaic cable 6 is not in a tight state during laying, so that the fixed lifting component can clamp and lift the photovoltaic cable 6 to a certain height. Then the cleaning component cleans the surface of the photovoltaic cable 6 to prevent dust and dirt on the surface of the photovoltaic cable 6 from affecting the repair process of the photovoltaic cable 6. Then the repair component 7 and the coating component 8 cooperate with each other to repair the damaged part of the photovoltaic cable 6. The repair process is that the repair component 7 first sticks a layer of repair tape, and then the coating component 8 applies a layer of waterproof tape. The damaged part of the photovoltaic cable 6 is repaired three times. The cooperation between the repair component 7 and the coating component 8 improves the repair effect of the photovoltaic cable 6. Bentonite can absorb moisture near the photovoltaic cable 6, and after absorption, it can expand to form a rubber to protect the photovoltaic cable 6. At the same time, diatomaceous earth has an insect-proof effect, which can prevent insects from approaching the photovoltaic cable 6 and damaging the photovoltaic cable 6, thereby ensuring the normal use of the repaired photovoltaic cable 6.

[0057] Example

[0058] like Figure 1-9As shown, a photovoltaic cable repair device is used in a photovoltaic cable repair process of embodiment 1, comprising a mounting plate 1 and four support legs 2 mounted on the lower side of the mounting plate 1 in a rectangular array by bolts, a universal wheel 4 is mounted on the lower side of the support leg 2 by bolts, a sliding plate 28 is connected to the mounting plate 1 for sliding back and forth through pulleys and slide rails, a driving assembly is provided on the sliding plate 28 for driving the sliding plate 28 to slide back and forth along the mounting plate 1, two translation frames 5 are connected to the sliding plate 28 for sliding left and right through a slide groove and a slider, the two translation frames 5 are symmetrically arranged with the center line of the sliding plate 28 as the center, and a first lead screw is provided on the upper side of the sliding plate 28 for driving the two translation frames 5 to move relative to or away from each other Transmission mechanism 15, two sets of arc-shaped slide rails 18 are symmetrically provided on the opposite sides of the two translation frames 5 by bolts, and the two sets of arc-shaped slide rails 18 each include two arc-shaped slide rails 18 located on the front and rear sides of the translation frame 5, and the left and right arc-shaped slide rails 18 can cooperate to form a circular slide rail, and an arc-shaped plate 19 is slidably connected in the front and rear arc-shaped slide rails 18, and the two arc-shaped plates 19 can cooperate to form a circular ring plate, and the outer sides of the two arc-shaped plates 19 are both installed with half gear rings 20 by bolts, and the two half gear rings 20 can cooperate to form a complete gear ring, and the two translation frames 5 are both provided with a gear transmission mechanism 21 that meshes with the half gear rings 20, because the gear transmission structure 21 meshes with the half gear rings 20;

[0059] When the photovoltaic cable 6 repair device is not powered on, the two arc-shaped slide rails 18 and the arc-shaped plate 19 are connected to each other, so the arc-shaped plate 19 cannot be separated from the arc-shaped slide rail 18. When the photovoltaic cable 6 repair device is powered on, the gear transmission mechanism 21 and the half-gear ring 20 engage with each other to limit the arc-shaped plate 19, so the arc-shaped plate 19 cannot be separated from the arc-shaped slide rail 18. The inner sides of the two arc-shaped plates 19 are respectively provided with a repair component 7 and a coating component 8. The two translation frames 5 are symmetrically provided with two sets of left and right cleaning components, and the cleaning components are located below the arc-shaped slide rail 18.

[0060] Two sets of fixed lifting components for clamping and fixing the photovoltaic cable 6 are symmetrically arranged at the front and rear ends of the mounting plate 1;

[0061] The supporting leg 2 is provided with a supporting assembly for supporting and fixing the photovoltaic cable repair device.

[0062] When in use, the staff will push the photovoltaic cable repair device to move just above the photovoltaic cable 6, start the supporting assembly to support the photovoltaic cable repair device to prevent the photovoltaic cable repair device from moving during use, and then the staff will control the fixed lifting assembly to clamp the front and rear ends of the damaged part of the photovoltaic cable 6, and drive the photovoltaic cable 6 to move upward into the cleaning assembly, and then control the first screw transmission mechanism 15 to drive the left and right translation frames 5 to move relatively until the two cleaning assemblies are close to each other, and then the staff will start the cleaning assembly to clean the surface of the photovoltaic cable 6. At the same time, the driving assembly drives the sliding plate 28 to move back and forth repeatedly, so that the cleaning assembly can repeatedly clean the surface of the photovoltaic cable 6 back and forth, ensuring the cleaning effect of the cleaning assembly on the photovoltaic cable 6. After the cleaning is completed, the staff will control the first screw transmission mechanism 15 to make the two translation frames 5 move away from each other, and then the staff will control the fixed lifting assembly to clamp the front and rear ends of the damaged part of the photovoltaic cable 6, and then The fixed lifting assembly continues to drive the photovoltaic cable 6 to move upward until the axis of the photovoltaic cable 6 is concentric with the axis of the curved plate 19. After that, the staff controls the first screw transmission mechanism 15 to drive the two translation frames 5 to approach each other, and make the two curved slide rails 18 and the two curved plates 19 cooperate and connect with each other. After the connection is completed, the staff starts the gear transmission mechanism 21 to drive the two curved plates 19 to rotate along the curved slide rails 18 and the driving assembly drives the sliding plate 28 to slide back and forth, so that the repair assembly 7 and the coating assembly 8 inside the curved plate 19 repeatedly repair the surface of the photovoltaic cable 6. After the repair is completed, the staff controls the first screw transmission mechanism 15 to drive the two translation frames 5 away from each other, and then the fixed lifting assembly drives the repaired photovoltaic cable 6 to move down to the original position of the photovoltaic cable 6. Finally, the staff releases the support of the support assembly to the photovoltaic cable repair device and pushes the photovoltaic cable repair device to leave.

[0063] In this embodiment, the driving assembly includes a rotating motor 12 installed on the upper side of the sliding plate 28 by bolts, a rotating gear 13 installed on the output shaft of the rotating motor 12, and a rack 14 installed on the upper side of the mounting plate 1 by bolts. The rotating gear 13 and the rack 14 are engaged with each other. When in use, the rotating motor 12 can drive the rotating gear 13 to rotate. Under the action of the mutual engagement of the rotating gear 13 and the rack 14, the driving assembly can drive the sliding plate 28 to move forward and backward along the mounting plate 1, thereby realizing the repair, cleaning and coating of the front and rear positions of the photovoltaic cable 6 by the repair assembly 7, the cleaning assembly and the coating assembly 8.

[0064] In this embodiment, the repair component 7 includes a first mounting frame 701 mounted on the inner side of the arc plate 19 by bolts, a first sliding frame 702 connected to the first mounting frame 701 by sliding forward and backward through a slider and a slide groove, two first mounting blocks 703 symmetrically arranged on the inner side of the first sliding frame 702, two rotating blocks 708 symmetrically connected to the opposite sides of the two first mounting blocks 703 by bearings, a tape shaft 704 detachably connected to the opposite sides of the two rotating blocks 708 by bolts, two first elastic telescopic shafts 707 arranged on the side of the rotating block 708 close to the photovoltaic cable 6, and a first elastic telescopic shaft 707 rotatably connected to the two first elastic The guide roller 705 on the opposite side of the telescopic shaft 707 and the upper side of the two rotating blocks 708 are both provided with a notch for inserting the tape shaft 704, and the two rotating blocks 708 are both installed with a fixing block by bolts to fix the tape shaft 704 in the notch. The outer surface of the guide roller 705 is covered with a sticky layer 706. The sticky layer 706 has a lower stickiness than the sticky surface of the repair tape 709. The repair tape 709 is sleeved on the tape shaft 704, and the non-sticky surface of one end of the repair tape 709 is adhered to the outer side of the sticky layer 706. The material of the sticky layer 706 is silicone rubber. The front side of the first sliding frame 702 is integrally formed with a pull block 27.

[0065] When in use, the staff controls the sliding plate 28 to move away from the fixed clamping assembly through the driving assembly, and then the staff pulls out the first sliding frame 702, and then removes the tape shaft 704 and puts the repair tape 709 on the tape shaft 704. After the installation is completed, the tape shaft 704 is reinstalled on the rotating block 708, and one end of the repair tape 709 is adhered to the outer surface of the guide roller 705. Then, the staff pushes the first sliding frame 702 back into the first mounting frame 701. Under the action of the first elastic telescopic shaft 707, when the photovoltaic cable 6 moves to the two When the guide rollers 705 are between the guide rollers 705, the first elastic telescopic shaft 707 drives the guide roller 705 to contact the photovoltaic cable 6. At the same time, the viscosity of the adhesive layer 706 on the surface of the guide roller 705 is less than the viscosity of the repair tape 709. Under the action of the gear transmission mechanism 21, the arc plate 19 can rotate along the arc slide rail 18, thereby driving the repair component 7 to rotate along the outer surface of the photovoltaic cable 6. When the repair component 7 moves along the surface of the photovoltaic cable 6, the repair tape 709 can be adhered to the side of the photovoltaic cable 6 under the action of the guide roller 705, thereby repairing the damaged part of the photovoltaic cable 6.

[0066] In this embodiment, the coating assembly 8 includes a second mounting frame 801 installed on the inner side of the arc plate 19 by bolts, a second sliding frame 802 connected to the first mounting frame 701 for sliding forward and backward, a glue storage box 803 installed on the inner side of the second sliding frame 802 by bolts, and a coating roller 804 arranged in the glue storage box 803.

The telescopic cavity 807 has a telescopic hole 808 connected to the inside of the glue storage box 803. There is a second elastic telescopic shaft 805, and a telescopic block 806 is installed at the output end of the second elastic telescopic shaft 805. The front and rear ends of the coating roller 804 pass through the telescopic hole 808 and are rotatably connected to the side of the telescopic block 806 through bearings. The telescopic block 806 can push the coating roller 804 to move left and right along the telescopic hole 808 under the action of the second elastic telescopic shaft 805. The side of the telescopic block 806 close to the coating roller 804 is in sealing contact with the inner wall of the telescopic cavity 807.

[0067] When in use, the staff first pulls out the second sliding frame 802, removes the sealing cap 809 and fills the glue storage box 803 with repair glue, and then the staff pushes the second sliding frame 802 back into the second mounting frame 801. When coating the photovoltaic cable 6, the side of the photovoltaic cable 6 pushes the coating roller 804 to move into the glue storage box 803. At this time, the coating roller 804 is no longer in contact with the opening. The outer surface of the coating roller 804 can pick up the glue in the glue storage box 803 and coat the surface of the photovoltaic cable 6 under the action of the gear transmission mechanism 21. When coating the photovoltaic cable 6 or not, the telescopic block 806 can push the coating roller 804 to seal the opening under the action of the second elastic telescopic shaft 805, thereby closing the inside of the glue storage box 803 and preventing the glue from flowing out and being wasted.

[0068] Preferably, magnets are provided on the inner sides of the first mounting frame 701 and the second mounting frame 801 to prevent the first sliding frame 702 and the second sliding frame 802 from sliding out of the first mounting frame 701 and the second mounting frame 801 when the coating assembly 8 and the repair assembly 7 are moving;

[0072] During use, the lifting plate 25 moves downward under the action of the second screw mechanism until the axis of the clamping plate 24 is on the same axis as the photovoltaic cable 6. Then, under the action of the third screw transmission mechanism 26, the two clamping plates 24 approach each other and are on the outer side of the photovoltaic cable 6. At this time, the photovoltaic cable 6 is clamped and fixed by the two clamping plates 24. Then, under the action of the second screw mechanism, the two clamping plates 24 can drive the photovoltaic cable 6 to move up and down, which improves the convenience of the staff in moving the photovoltaic cable 6 up and down, and at the same time ensures the stability when repairing the photovoltaic cable 6.

[0073] In this embodiment, electric push rods 3 are symmetrically installed on the left and right sides of the support legs 2 by bolts, and the multiple electric push rods 3 are electrically connected to each other so that the multiple electric push rods 3 can be extended and retracted synchronously. When in use, the output shaft of the electric push rod 3 can extend downward and contact the ground, thereby lifting the photovoltaic cable 6 repair device upward so that the universal wheel 4 is not in contact with the ground. At this time, the photovoltaic cable 6 repair device cannot move, thereby ensuring the reliability of the photovoltaic cable 6 repair device when repairing the photovoltaic cable 6.
