Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power station busbar connection and grid connection equipment, and particularly to a high-efficiency distributed photovoltaic power station busbar connection and grid connection device and its usage method. Background Art

[0002] Currently, distributed generation systems or microgrid systems are all comprehensive utilization methods of power generation and energy with broad development prospects, and such photovoltaic grid connection systems have been widely applied in the field of photovoltaic power generation. With the popularization of distributed generation systems and microgrid systems and the increase in aggregated electric energy, the impact of their safe and stable operation on the safe and stable operation of the power grid is becoming increasingly significant.

[0003] Among them, the grid connection device mainly ensures the power flow of two or more lines. And in order to improve the connection speed, most grid connection devices adopt a snap design. However, affected by the high-intensity light in the photovoltaic station environment, the elasticity of the claw inside the grid connection device decreases, and finally the connection becomes unstable. 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 high-efficiency distributed photovoltaic power station busbar connection and grid connection device, including a housing. A fixed box is connected through the side wall of the housing. An input wire is arranged on the inner wall of the fixed box. A chute is opened on the inner wall of the fixed box. A sliding block is slidably connected to the outer wall of the chute. A rotating plate is rotatably connected to the inner wall of the sliding block. A torsion spring is fixedly connected to the outer wall of the rotating plate. A first spring is fixedly connected to the top of the sliding block. A pulling assembly is fixedly connected to the side wall of the fixed box;

[0005] A clamping mechanism, the clamping mechanism includes a scraper fixedly connected to the side wall of the rotating plate. A rotating frame is fixedly connected to the top of the scraper. A first telescopic rod is rotatably connected to the inner wall of the rotating frame. A rotating rod is rotatably connected to the inner wall of the fixed box. One end of the first telescopic rod away from the rotating frame is fixedly connected to the side wall of the rotating rod. A fixed rod is fixedly connected to the side wall of the rotating rod;

[0006] An energizing mechanism, the energizing mechanism includes a first sliding track fixedly connected to the inner wall of the fixed box. A sliding plate is slidably connected to the inner wall of the first sliding track. A contact plate is fixedly connected to the side wall of the sliding plate. One end of the fixed rod away from the rotating rod is fixedly connected to the side wall of the sliding plate. A parallel wire is fixedly connected to the side wall of the sliding plate. An output wire is fixedly connected to the side wall of the parallel wire. Before use, install the housing at the required position, and strip a relatively long wire skin from the end of the input wire. Then insert the stripped copper wire into the inside of the fixed box, as shown in Figure 1In the state where the input wire penetrates deep into the fixed box, the end of the scraper will contact the outer wall of the input wire and will not restrict the input wire. However, after the staff inserts it to a sufficient depth and then pulls the input wire outwards by a certain distance, due to the influence of its own inclination angle, the end of the scraper will embed into the wire skin of the input wire. As the input wire moves outwards, at this time, the scraper will drive the sliding block to slide upwards along the inner wall of the chute through the rotating plate. During this process, the scraper will hinder the outward movement of the input wire. And when the rotating plate moves upwards, the rotating plate forces one end of the first telescopic rod to tilt upwards through the rotating frame. The tilted end of the first telescopic rod forces the fixed rod to swing downwards with the rotating rod as the center point. The downward-swinging fixed rod drives the sliding plate to slide downwards along the inner wall of the first sliding track. The moving sliding plate will drive the contact plate to closely adhere to the outer wall of the copper wire of the input wire. Through the application of the above components, while completing the power connection, if the input wire is subjected to an external tensile force, the scraper will force the contact plate to more closely adhere to the copper wire of the input wire, avoiding the phenomenon of loosening of the conventional claw after long-term use and improving the stability of the equipment connection.

[0007] Preferably, the pulling component includes a spring telescopic rod fixedly connected to the side wall of the fixed box. The end of the spring telescopic rod far from the fixed box is fixedly connected with a hydraulic box. A fixed frame is fixedly connected to the side wall of the hydraulic box. A first roller is rotatably connected to the inner wall of the fixed frame.

[0008] Preferably, the pulling component further includes a first gear fixedly connected to the side wall of the first roller. A second roller is rotatably connected to the inner wall of the fixed frame. A second gear is fixedly connected to the side wall of the second roller. The outer wall of the second gear is meshed with the outer wall of the first gear.

[0009] Preferably, the pulling component further includes a sliding rod fixedly connected to the side wall of the fixed box. A tooth mark is fixedly connected to the end of the sliding rod far from the fixed box. A hydraulic telescopic rod penetrates through the side wall of the hydraulic box. An obstruction block is fixedly connected to the bottom of the hydraulic telescopic rod. An adjusting component is fixedly connected to the side wall of the first roller. A second tooth bar is fixedly connected to the side wall of the fixed box. After the external force disappears, the spring telescopic rod will force each component to reset. And during the process of the spring telescopic rod driving the fixed frame to reset, the fixed frame will drive the pushing plate to contact the outer wall of the second tooth bar. Figure 7 For example, when the mounting plate drives the pushing plate to horizontally move to the left, the pushing plate will force the mounting plate to rotate clockwise. And the clockwise-rotating mounting plate will drive the first roller and the second roller to form a tendency of meshing rotation, and force the input wire between the first roller and the second roller to horizontally move a certain distance towards the direction of the outer shell. Through the application of the above components, every time the input wire is subjected to an excessive external tensile force, the first roller and the second roller will force the input wire to horizontally move a certain distance towards the direction of the outer shell, avoiding the same position from being pulled repeatedly, resulting in wear of the exposed wire skin of the input wire.

[0010] Preferably, the adjusting assembly includes a mounting disc fixedly connected to one end of the first roller away from the first gear. A plurality of inclined grooves are formed in the side wall of the mounting disc. A pushing plate is rotatably connected to the inner walls of the plurality of inclined grooves. A plurality of limiting grooves are formed in the surface of the mounting disc close to the first roller.

[0011] Preferably, the adjusting assembly further includes a second sliding track fixedly connected to the side wall of the fixed frame. An arc-shaped slider is slidably connected to the inner wall of the second sliding track. A third spring is fixedly connected to the side wall of the arc-shaped slider. By using the characteristic that the input wire will be straightened under tension, a pulling assembly is arranged inside the device. During the use of the input wire, it presents a state as shown in Figure 6 . When the input wire is subjected to an external pulling force, the input wire will move to the left. During this process, since the vertical surface of the arc-shaped slider contacts the plane of the limiting groove, the rotation of the mounting disc is restricted, and the mounting disc will restrict the rotation of the first roller. The first roller restricts the rotation of the second roller through the first gear and the second gear. Therefore, when the input wire moves to the left, the input wire will drive the first roller and the second roller to move synchronously. The outward-moving first roller and second roller drive the hydraulic tank to move through the fixed frame and force the spring telescopic rod to extend. The extended spring telescopic rod will extract the liquid inside the hydraulic telescopic rod through the hydraulic tank, forcing the hydraulic telescopic rod to contract. The contracted hydraulic telescopic rod moves upward through the blocking block and forces the blocking block to contact the inner wall of the tooth mark, restricting the outward movement of the hydraulic tank. Through the application of the above components, when the input wire is pulled strongly externally, the force received by the input wire will be transmitted to the fixed box through the first roller, the fixed frame, and the tooth mark, reducing the influence of the external force on the input wire and the contact plate, avoiding the direct action of the external force on the wire skin of the input wire and the end of the scraper, and avoiding excessive pressure on the end of the wire skin by the scraper, resulting in damage to the components.

[0012] Preferably, the adjusting assembly further includes a tooth bar fixedly connected to the inner wall of the chute. A sliding groove is formed in the inner wall of the sliding block. An arc-shaped slider is slidably connected to the inner wall of the sliding groove. A fourth spring is fixedly connected to the side wall of the arc-shaped slider. By using the characteristic that the rotating plate is pressed and moves upward along the inner wall of the chute when the device is in use, an arc-shaped slider and a tooth bar are arranged inside the device. When the rotating plate drives the sliding block to move upward, the sliding block drives the arc-shaped slider to move upward synchronously. During this process, the arc surface of the arc-shaped slider will contact the inner wall of the tooth bar, and the inner wall of the tooth bar will force the arc-shaped slider to slide along the inner wall of the sliding groove. As the sliding block continues to move upward, the arc-shaped slider will move upward synchronously. After the arc-shaped slider completes its upward movement, the plane at the bottom of the arc-shaped slider will contact the plane of the tooth bar, restricting the reset of the sliding block. Through the application of the above components, it is avoided that the input wire shakes slightly under the blowing of external wind, resulting in the loosening of the scraper, the decrease in the clamping force of the scraper on the input wire, and the phenomenon of unstable connection.

[0013] A method for using a high-efficiency distributed photovoltaic power station busbar connection and grid connection device, comprising the following steps:

[0014] S1: Install the device;

[0015] S2: Insert the wire;

[0016] S3: Start working.

[0017] The present invention has the following beneficial effects:

[0018] (1) Utilizing the characteristic that the outer skin of the cable is mostly rubber, the present invention is provided with a clamping mechanism and an energizing mechanism inside the device. Before use, the outer shell is installed at the required position, and the end of the input wire is stripped of a relatively long wire skin. Subsequently, the copper wire with the stripped wire skin is inserted into the inside of the fixed box, presenting a state as shown in Figure 1 . When the input wire penetrates deeper into the fixed box, the end of the scraper will contact the outer wall of the input wire without restricting the input wire. However, after the staff inserts it to a sufficient depth and then pulls the input wire out a certain distance, at this time, due to the influence of its own inclination angle, the end of the scraper will embed into the wire skin of the input wire, and as the input wire moves outwards, at this time, the scraper will drive the sliding block to slide upwards along the inner wall of the chute through the rotating plate. During this process, the scraper will hinder the outward movement of the input wire; and when the rotating plate moves upwards, the rotating plate forces one end of the first telescopic rod to tilt upwards through the rotating frame, and the tilted end of the first telescopic rod forces the fixed rod to swing downwards with the rotating rod as the center point. The downward-swinging fixed rod drives the sliding plate to slide downwards along the inner wall of the first sliding track, and the moving sliding plate drives the contact plate to closely adhere to the outer wall of the copper wire of the input wire. Through the application of the above components, while completing the power connection, if the input wire is subjected to an external tensile force, the scraper will force the contact plate to more closely adhere to the copper wire of the input wire, avoiding the phenomenon of loosening of the conventional claw after long-term use and improving the connection stability of the device.

[0019] (2) Utilizing the characteristic that when the above device is in use, the rotating plate is pressed to move upwards along the inner wall of the chute, the present invention is provided with an arc-shaped slider two and a toothed rod inside the device. When the rotating plate drives the sliding block to move upwards, the sliding block drives the arc-shaped slider two to move upwards synchronously. During this process, the arc surface of the arc-shaped slider two will contact the inner wall of the toothed rod, and the inner wall of the toothed rod will force the arc-shaped slider two to slide along the inner wall of the sliding groove. As the sliding block continues to move upwards, the arc-shaped slider two will move upwards synchronously. After the arc-shaped slider two completes its upward movement, the flat surface at the bottom of the arc-shaped slider two will contact the flat surface of the toothed rod, restricting the reset of the sliding block. Through the application of the above components, it is avoided that the input wire has slight jitter under the blowing of external wind, resulting in the loosening of the scraper, the decrease in the clamping force of the scraper on the input wire, and the phenomenon of unstable connection.

[0020] (3) By taking advantage of the characteristic that the above-mentioned input wire will be straightened under tension, a pulling component is provided inside the device. During the use of the input wire, it presents a state as shown in Figure 6 . When the input wire is subjected to an external tensile force, the input wire will move to the left. During this process, since the vertical surface of the arc-shaped slider 1 contacts the plane of the limit groove, the rotation of the mounting plate is restricted. The mounting plate restricts the rotation of the roller 1, and the roller 1 restricts the rotation of the roller 2 through the gear 1 and the gear 2. Therefore, when the input wire moves to the left, the input wire will drive the roller 1 and the roller 2 to move synchronously. The outward-moving roller 1 and roller 2 drive the hydraulic tank to move through the fixing frame, and force the spring telescopic rod to extend. The extended spring telescopic rod will extract the liquid inside the hydraulic telescopic rod through the hydraulic tank, forcing the hydraulic telescopic rod to contract. The contracted hydraulic telescopic rod moves upward through the blocking block, and forces the blocking block to contact the inner wall of the tooth mark, restricting the outward movement of the hydraulic tank. Through the application of the above components, when the input wire is pulled strongly externally, the force received by the input wire will be transmitted to the fixed box through the roller 1, the fixing frame and the tooth mark, reducing the impact of the external force on the input wire and the contact plate, and preventing the external force from directly acting on the wire skin of the input wire and the end of the scraper, avoiding excessive pressure on the end of the wire skin by the scraper and causing damage to the components.

[0021] (4) By taking advantage of the characteristic that the above-mentioned fixing frame moves outward, an adjusting component is provided inside the device. After the external force disappears, the spring telescopic rod will force each component to reset. During the process of the spring telescopic rod driving the fixing frame to reset, the fixing frame will drive the push plate to contact the outer wall of the tooth rod 2, as shown in Figure 7 . When the mounting plate drives the push plate to move horizontally to the left, the push plate will force the mounting plate to rotate clockwise. The clockwise-rotating mounting plate will drive the roller 1 and the roller 2 to form a tendency of meshing rotation, and force the input wire between the roller 1 and the roller 2 to move horizontally a certain distance towards the shell. Through the application of the above components, each time the input wire is subjected to an excessive external tensile force, the roller 1 and the roller 2 will force the input wire to move horizontally a certain distance towards the shell, avoiding being pulled multiple times at the same position and causing wear to the exposed wire skin of the input wire.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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.

[0037] Embodiment 1. Please refer to Figure 1 - Figure 5 , the present invention is a high-efficiency distributed photovoltaic power station busbar connection and grid connection device, including a housing 1. A fixed box 11 is connected through the side wall of the housing 1. An input wire 12 is arranged on the inner wall of the fixed box 11. A chute 13 is opened on the inner wall of the fixed box 11. A sliding block 14 is slidably connected to the outer wall of the chute 13. A rotating plate 15 is rotatably connected to the inner wall of the sliding block 14. A turbine spring 16 is fixedly connected to the outer wall of the rotating plate 15. A first spring 17 is fixedly connected to the top of the sliding block 14. A pulling assembly 4 is fixedly connected to the side wall of the fixed box 11;

[0038] A clamping mechanism 2, the clamping mechanism 2 includes a scraper 21 fixedly connected to the side wall of the rotating plate 15. A rotating frame 22 is fixedly connected to the top of the scraper 21. A first telescopic rod 23 is rotatably connected to the inner wall of the rotating frame 22. A rotating rod 24 is rotatably connected to the inner wall of the fixed box 11. One end of the first telescopic rod 23 away from the rotating frame 22 is fixedly connected to the side wall of the rotating rod 24. A fixed rod 25 is fixedly connected to the side wall of the rotating rod 24;

[0039] An energizing mechanism 3, the energizing mechanism 3 includes a first sliding track 31 fixedly connected to the inner wall of the fixed box 11. A sliding plate 32 is slidably connected to the inner wall of the first sliding track 31. A contact plate 33 is fixedly connected to the side wall of the sliding plate 32. One end of the fixed rod 25 away from the rotating rod 24 is fixedly connected to the side wall of the sliding plate 32. A parallel wire 34 is fixedly connected to the side wall of the sliding plate 32. An output wire 35 is fixedly connected to the side wall of the parallel wire 34. Before use, the housing 1 is installed at the required position, and the end of the input wire 12 is stripped of a longer wire skin. Subsequently, the copper wire with the stripped wire skin is inserted into the interior of the fixed box 11, presenting as Figure 1When the input wire 12 extends deep into the fixed box 11, the end of the scraper 21 will contact the outer wall of the input wire 12 without restricting the input wire 12. After the insertion by the staff reaches a sufficient depth, the input wire 12 is then pulled outwards by a certain distance. At this time, due to the influence of its own inclination angle, the end of the scraper 21 will embed into the wire skin of the input wire 12. As the input wire 12 moves outwards, the scraper 21 will drive the sliding block 14 to slide upwards along the inner wall of the chute 13 through the rotating plate 15. During this process, the scraper 21 will hinder the outward movement of the input wire 12. And when the rotating plate 15 moves upwards, the rotating plate 15 forces one end of the first telescopic rod 23 to tilt upwards through the rotating frame 22. The tilted end of the first telescopic rod 23 forces the fixed rod 25 to swing downwards with the rotating rod 24 as the center point. The downward-swinging fixed rod 25 drives the sliding plate 32 to slide downwards along the inner wall of the first sliding track 31. The moving sliding plate 32 will drive the contact plate 33 to closely adhere to the outer wall of the copper wire of the input wire 12. Through the application of the above components, while the power connection is completed, if the input wire 12 is subjected to an external tensile force, the scraper 21 will force the contact plate 33 to more closely adhere to the copper wire of the input wire 12, avoiding the phenomenon of loosening of the conventional claw after long-term use and improving the stability of the equipment connection.

[0040] Embodiment 2. Please refer to Figure 6 - Figure 11 In the high-efficiency distributed photovoltaic power station busbar grid connection device of the present invention, on the basis of Embodiment 1, the pulling component 4 includes a spring telescopic rod 41 fixedly connected to the side wall of the fixed box 11. One end of the spring telescopic rod 41 away from the fixed box 11 is fixedly connected to a hydraulic box 42. A fixed frame 43 is fixedly connected to the side wall of the hydraulic box 42. A first roller 44 is rotatably connected to the inner wall of the fixed frame 43.

[0041] The pulling component 4 further includes a first gear 45 fixedly connected to the side wall of the first roller 44. A second roller 46 is rotatably connected to the inner wall of the fixed frame 43. A second gear 47 is fixedly connected to the side wall of the second roller 46. The outer wall of the second gear 47 is meshed with the outer wall of the first gear 45.

[0042] The pulling component 4 further includes a sliding rod 48 fixedly connected to the side wall of the fixed box 11. A tooth mark 49 is fixedly connected to one end of the sliding rod 48 away from the fixed box 11. A hydraulic telescopic rod 410 is connected through the side wall of the hydraulic box 42. A blocking block 411 is fixedly connected to the bottom of the hydraulic telescopic rod 410. An adjusting component 5 is fixedly connected to the side wall of the first roller 44. A second tooth bar 412 is fixedly connected to the side wall of the fixed box 11. After the external force disappears, the spring telescopic rod 41 will force each component to reset. And during the process of the spring telescopic rod 41 driving the fixed frame 43 to reset, the fixed frame 43 will drive the pushing plate 53 to contact the outer wall of the second tooth bar 412. As Figure 7, when the installation disk 51 drives the push plate 53 to move horizontally to the left, the push plate 53 will force the installation disk 51 to rotate clockwise. The clockwise rotating installation disk 51 will drive the first roller 44 and the second roller 46 to form a tendency of meshing rotation, and force the input wire 12 between the first roller 44 and the second roller 46 to move horizontally a certain distance towards the housing 1. Through the application of the above components, every time the input wire 12 is subjected to excessive external tensile force, the first roller 44 and the second roller 46 will force the input wire 12 to move horizontally a certain distance towards the housing 1, avoiding being pulled multiple times at the same position, resulting in wear of the wire skin exposed outside the input wire 12.

[0043] The adjusting component 5 includes an installation disk 51 fixedly connected to one end of the first roller 44 away from the first gear 45. A plurality of inclined grooves 52 are formed in the side wall of the installation disk 51. A push plate 53 is rotatably connected to the inner walls of the plurality of inclined grooves 52. A plurality of limiting grooves 54 are formed in the surface of the installation disk 51 close to the first roller 44.

[0044] The adjusting component 5 further includes a sliding track two 55 fixedly connected to the side wall of the fixed frame 43. An arc-shaped slider one 56 is slidably connected to the inner wall of the sliding track two 55. A third spring 57 is fixedly connected to the side wall of the arc-shaped slider one 56. Utilizing the characteristic that the input wire 12 will be straightened when subjected to tensile force, a pulling component 4 is arranged inside the device. The input wire 12 presents a state as follows during use Figure 6 When the input wire 12 is subjected to external tensile force, the input wire 12 will move to the left. During this process, since the vertical surface of the arc-shaped slider one 56 contacts the plane of the limiting groove 54, the rotation of the installation disk 51 is restricted. The installation disk 51 restricts the rotation of the first roller 44, and the first roller 44 restricts the rotation of the second roller 46 through the first gear 45 and the second gear 47. Therefore, when the input wire 12 moves to the left, the input wire 12 will drive the first roller 44 and the second roller 46 to move synchronously. The outward-moving first roller 44 and second roller 46 drive the hydraulic tank 42 to move through the fixed frame 43, and force the spring telescopic rod 41 to extend. The extended spring telescopic rod 41 will extract the liquid inside the hydraulic telescopic rod 410 through the hydraulic tank 42, forcing the hydraulic telescopic rod 410 to contract. The contracted hydraulic telescopic rod 410 moves upward through the blocking block 411, and forces the blocking block 411 to contact the inner wall of the tooth marks 49, restricting the outward movement of the hydraulic tank 42. Through the application of the above components, when the input wire 12 is subjected to strong external pulling force, the force received by the input wire 12 will be transmitted to the fixed box 11 through the first roller 44, the fixed frame 43 and the tooth marks 49, reducing the influence of the external force on the input wire 12 and the contact plate 33, avoiding the external force directly acting on the wire skin of the input wire 12 and the end of the scraper 21, and avoiding the scraper 21 causing excessive pressure on the end of the wire skin, resulting in damage to the components.

[0045] The adjusting component 5 further includes a toothed rod 58 fixedly connected to the inner wall of the sliding groove 13. A sliding groove 59 is formed in the inner wall of the sliding block 14. A second arc-shaped slider 510 is slidably connected to the inner wall of the sliding groove 59. A fourth spring 511 is fixedly connected to the side wall of the second arc-shaped slider 510. When the above equipment is used, by virtue of the feature that the rotating plate 15 is pressed to move upward along the inner wall of the sliding groove 13, a second arc-shaped slider 510 and a toothed rod 58 are arranged inside the equipment. When the rotating plate 15 drives the sliding block 14 to move upward, the sliding block 14 drives the second arc-shaped slider 510 to move upward synchronously. During this process, the arc surface of the second arc-shaped slider 510 will contact the inner wall of the toothed rod 58, and the inner wall of the toothed rod 58 will force the second arc-shaped slider 510 to slide along the inner wall of the sliding groove 59. As the sliding block 14 continues to move upward, the second arc-shaped slider 510 will move upward synchronously. After the second arc-shaped slider 510 finishes moving upward, the flat surface at the bottom of the second arc-shaped slider 510 will contact the flat surface of the toothed rod 58, restricting the reset of the sliding block 14. Through the application of the above components, it is avoided that the input wire 12 shakes slightly under the blowing of external wind, resulting in the loosening of the scraper 21, the decrease in the clamping force of the scraper 21 on the input wire 12, and the phenomenon of unstable connection.

[0046] The usage method of the high-efficiency distributed photovoltaic power station busbar connection and grid connection device includes the following steps:

[0047] S1: Install the equipment;

[0048] S2: Insert the wire;

[0049] S3: Start working.

[0050] A specific application of this embodiment is as follows: Before use, install the housing 1 at the required position, strip a relatively long wire skin from the end of the input wire 12, and then insert the stripped copper wire into the inside of the fixed box 11, presenting as Figure 1When the input wire 12 extends deep into the fixed box 11, the end of the scraper 21 will contact the outer wall of the input wire 12 without restricting the input wire 12. After the staff inserts it to a sufficient depth and then pulls the input wire 12 outwards by a certain distance, due to the influence of its own inclination angle, the end of the scraper 21 will embed into the wire skin of the input wire 12. As the input wire 12 moves outwards, at this time, the scraper 21 will drive the sliding block 14 to slide upwards along the inner wall of the sliding groove 13 through the rotating plate 15. During this process, the scraper 21 will hinder the outward movement of the input wire 12; and when the rotating plate 15 moves upwards, the rotating plate 15 forces one end of the first telescopic rod 23 to tilt upwards through the rotating frame 22. The tilted end of the first telescopic rod 23 forces the fixed rod 25 to swing downwards with the rotating rod 24 as the center point. The downward-swinging fixed rod 25 drives the sliding plate 32 to slide downwards along the inner wall of the first sliding track 31. The moving sliding plate 32 will drive the contact plate 33 to closely adhere to the outer wall of the copper wire of the input wire 12. Through the application of the above components, while completing the power connection, if the input wire 12 is subjected to an external tensile force, the scraper 21 will force the contact plate 33 to more closely adhere to the copper wire of the input wire 12, avoiding the phenomenon of loosening of the conventional claw after long-term use and improving the stability of the equipment connection.

[0051] When using the above equipment, taking advantage of the characteristic that the rotating plate 15 is pressed to move upwards along the inner wall of the sliding groove 13, an arc-shaped slider two 510 and a toothed rod 58 are arranged inside the equipment. When the rotating plate 15 drives the sliding block 14 to move upwards, the sliding block 14 drives the arc-shaped slider two 510 to move upwards synchronously. During this process, the arc surface of the arc-shaped slider two 510 will contact the inner wall of the toothed rod 58. The inner wall of the toothed rod 58 will force the arc-shaped slider two 510 to slide along the inner wall of the sliding groove 59. As the sliding block 14 continues to move upwards, the arc-shaped slider two 510 will move upwards synchronously. After the arc-shaped slider two 510 completes its upward movement, the flat surface at the bottom of the arc-shaped slider two 510 will contact the flat surface of the toothed rod 58, restricting the reset of the sliding block 14. Through the application of the above components, it is avoided that the input wire 12 has slight jitter under the blowing of external wind, resulting in the loosening of the scraper 21, the decrease in the clamping force of the scraper 21 on the input wire 12, and the phenomenon of unstable connection.

[0052] Taking advantage of the characteristic that when the above input wire 12 is subjected to a tensile force, the input wire 12 will be straightened, a pulling component 4 is arranged inside the equipment. During the use of the input wire 12, it presents as Figure 6When the input wire 12 is subjected to an external tensile force, the input wire 12 will move to the left. During this process, since the vertical surface of the arc-shaped slider 56 contacts the plane of the limit groove 54, the rotation of the mounting plate 51 is restricted. The mounting plate 51 restricts the rotation of the first roller 44, and the first roller 44 restricts the rotation of the second roller 46 through the first gear 45 and the second gear 47. Therefore, when the input wire 12 moves to the left, the input wire 12 will drive the first roller 44 and the second roller 46 to move synchronously. The outward-moving first roller 44 and second roller 46 drive the hydraulic tank 42 to move through the fixing bracket 43, and force the spring telescopic rod 41 to extend. The extended spring telescopic rod 41 will extract the liquid inside the hydraulic telescopic rod 410 through the hydraulic tank 42, forcing the hydraulic telescopic rod 410 to contract. The contracted hydraulic telescopic rod 410 moves upward through the blocking block 411, and forces the blocking block 411 to contact the inner wall of the tooth mark 49, restricting the outward movement of the hydraulic tank 42. Through the application of the above components, when the input wire 12 is pulled strongly externally, the force received by the input wire 12 will be transmitted to the fixed box 11 through the first roller 44, the fixing bracket 43, and the tooth mark 49, reducing the influence of the external force on the input wire 12 and the contact plate 33, and preventing the external force from directly acting on the wire skin of the input wire 12 and the end of the scraper 21, and avoiding the scraper 21 causing excessive pressure on the end of the wire skin and damaging the components.

[0053] Taking advantage of the characteristic that the fixing bracket 43 moves outward, an adjusting component 5 is provided inside the device. After the external force disappears, the spring telescopic rod 41 will force each component to reset. During the process of the spring telescopic rod 41 driving the fixing bracket 43 to reset, the fixing bracket 43 will drive the push plate 53 to contact the outer wall of the second tooth rod 412. As Figure 7 shown, when the mounting plate 51 drives the push plate 53 to move horizontally to the left, the push plate 53 will force the mounting plate 51 to rotate clockwise. The clockwise-rotating mounting plate 51 will drive the first roller 44 and the second roller 46 to form a tendency of meshing rotation, and force the input wire 12 between the first roller 44 and the second roller 46 to move horizontally a certain distance towards the housing 1. Through the application of the above components, each time the input wire 12 is subjected to an excessive external tensile force, the first roller 44 and the second roller 46 will force the input wire 12 to move horizontally a certain distance towards the housing 1, avoiding being pulled multiple times at the same position and causing wear to the exposed wire skin of the input wire 12.
