Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment maintenance technology, and in particular to a photovoltaic equipment maintenance and protection climbing device with secondary protection function. Background Technology

[0002] Photovoltaic equipment refers to equipment that uses the photovoltaic effect to convert solar energy into electrical energy. Photovoltaic equipment mainly consists of solar panels, support structures, inverters, cables, etc. Among them, solar panels are the core components, which are composed of multiple solar cells and convert solar radiation energy into direct current energy. Solar panels are installed at a high position by a support. When problems occur and maintenance is required, operators need to use climbing equipment to climb to complete the maintenance task.

[0003] However, existing climbing equipment is often only equipped with Level 1 protection, which is a fixed safety rope connected to the operator's protective clothing through a buckle. During long-term use, the safety rope is prone to wear and tear. If the safety rope fails, the operator will be completely exposed to danger during the climbing process, which poses a safety hazard and has the problem of low practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a photovoltaic equipment maintenance and protection climbing device with secondary protection function, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A photovoltaic equipment maintenance protective climbing device with secondary protection function includes a support frame, a sliding following structure, and a rope component connecting the sliding following structure and the protective clothing of the operator;

[0008] The support includes a base plate that can be fixed to the ground, a vertical rod, uprights located on the left and right sides of the vertical rod, and several horizontal rods. The horizontal rods are used to connect the left and right ends of the vertical rod to the corresponding uprights. The vertical rod and uprights are vertically fixed to the base plate.

[0009] The sliding follow structure includes a slide rail component that provides an annular slide rail;

[0010] The slide rail component includes an inner slide plate fixed to the vertical rod and an outer slide plate fixed to the bracket that surrounds the inner slide plate. The inner slide plate and the outer slide plate are spaced apart to fix the slide rail around the front and rear sides of the vertical rod.

[0011] The sliding follow structure also includes a ratchet component, a rotation and scaling mechanism, and a secondary protection structure;

[0012] The ratchet component includes a connecting seat with a slide rail, rotating rings adapted to the slide rails at the left and right ends of the connecting seat, and a rotating seat sleeved on the outside of the rotating rings and rotatably connected to the connecting seat.

[0013] The secondary protection structure within the slide rail includes a mounting base placed between two rotating rings and fixed to the connecting seat, and two sliding blocks slidably connected to the mounting base, with a brake pad fixed on each sliding block;

[0014] The rotation and scaling mechanism is used to convert the rotation of the rotating seat into the sliding of the two brake pads along the front and back direction of the vertical rod;

[0015] When the operator climbs up and pulls the connecting seat upwards via the rope component, the rotating ring rotates counterclockwise in the slide rail, the rotating seat does not rotate, and the two brake pads retract towards the mounting seat.

[0016] When the operator falls, the connecting seat moves down, causing the rotating ring to rotate clockwise inside the slide. The rotating seat rotates clockwise, and two brake pads extend out of the mounting seat and engage with the inner wall of the slide.

[0017] In the above technical solution, the clamp for connecting a busbar to a six-split conductor according to the present invention has the following beneficial effects:

[0018] The beneficial effects of this invention are as follows:

[0019] During the operator's ascent, in addition to the basic safety rope protection of the hook, the short safety rope is connected to the long safety rope through the connecting plate, and the sliding follow structure climbs with the operator. If the operator accidentally misses the mark and falls, the rotating ring set in the sliding follow structure rotates clockwise, which will drive the rotating seat to rotate clockwise in sync, so that the brake pad can slide out and contact the inner wall, effectively braking and preventing the operator from continuing to descend, reducing the risk of falling.

[0020] During the operator's descent, the greater the force exerted by the short safety rope on the sliding follower structure, the greater the push-out force applied to the brake pads inside the secondary protection structure. This results in a greater force and friction between the brake pads and the inner wall, which can more effectively restrain and prevent the movement of the sliding follower structure, providing further safety protection. In the event of an accident, the operator can more reliably rely on the secondary protection structure to ensure their safety.

[0021] The ratchet groove inside the rotating ring works in conjunction with the pawl on the rotating seat to automatically trigger protection when an operator falls, without the need for operator intervention. This speeds up the response and provides protection quickly to reduce injuries caused by accidents. It also forms a double protection with the basic safety rope, providing more safety for the operator.

[0022] By setting up a support structure in conjunction with a sliding follower structure and a secondary protection structure, after the operator climbs to the top of the device, they can turn the handle to move the sliding follower structure and the secondary protection structure into the rear slide of the device. When the short safety rope is pulled, the brake pad pops out and is fixed, forming a fixed fulcrum to provide support for the long and short safety ropes, ensuring the stability and safety of the operator at the top position and facilitating the operator to carry out maintenance.

[0023] By pulling the sliding sleeve to adjust the position of the guard plate, the operator can flip the guard plate to the waist position. The position of the guard plate is fixed by the meshing of the toothed block and the toothed groove, making the guard plate a stable fulcrum, providing support for the waist and reducing the burden on the operator's legs. This allows the operator to stand stably at the top position, allowing the operator's arms and hands to work more freely. Under stable support, the operator can perform tasks that require hand operation, thereby improving work efficiency and accuracy.

[0024] By fixing the position of the guard plate, a stable fulcrum is ensured, providing additional safety protection. After fixing the position of the guard plate, the operator's waist and legs are clamped between the crossbar and the guard plate, forming a stable connection, which further increases the safety of the operator's maintenance work and enhances the practicality of the device. By rotating the position of the guard plate, it can be adapted to the waist of operators of different heights, further enhancing the applicability of the device. Attached Figure Description

[0039] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] It should be noted that the terms "above," "one end," "up," etc., used herein indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of illustrative purposes and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention. In addition, the terms "part," "two parts," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] like Figures 1-12 As shown, a photovoltaic equipment maintenance protective climbing device with secondary protection function includes a support frame, a sliding following structure 8, and a rope component connecting the sliding following structure 8 and the operator's protective clothing.

[0042] The bracket includes a base plate 1 that can be fixedly inserted into the ground, a vertical rod 5, uprights 2 located on the left and right sides of the vertical rod 5, and several horizontal bars 4. The horizontal bars 4 are used to connect the left and right ends of the vertical rod 5 to the corresponding uprights 2. The vertical rod 5 and the uprights 2 are vertically fixed to the base plate 1.

[0043] Specifically, the support includes two base plates 1. A vertical pole 2 is fixedly installed at the top center of the base plate 1. Support rods 3 are connected to the base plate 1 on both sides near the bottom. A vertical pole 5 is fixedly connected to the two vertical poles 2 near the middle by several horizontal bars 4. A support base 6 is fixedly installed between the two vertical poles 2 near the bottom. A hook 7 is fixedly installed at the front of the vertical pole 2 near the top. A sliding following structure 8 is provided on the outside of the vertical pole 5.

[0044] Preferably, the base plate 1 has a fixing groove at the center of the bottom of the upright 2, and a reinforcing pile is slidably installed inside the fixing groove, with the bottom of the reinforcing pile being conical. This allows the base plate 1 to be fixedly inserted into the ground by the reinforcing pile. When facing soil, the overall stability of the device can be enhanced by inserting the reinforcing pile into the ground.

[0045] The sliding follow structure 8 includes a slide rail component that provides an annular slide rail 11;

[0046] The slide rail component includes an inner slide plate 10 fixed on the vertical rod 5 and an outer slide plate 9 fixed on the bracket to surround the inner slide plate 10. The inner slide plate 10 and the outer slide plate 9 are spaced apart to fix the slide rail 11 around the front and rear sides of the vertical rod 5. The slide rail 11 is generally oblong, with a semi-circular top and bottom.

[0047] The sliding follow structure 8 also includes a ratchet component, a rotation and scaling mechanism, and a secondary protection structure 23;

[0048] The ratchet assembly includes a connecting seat 13 through a slide 11, rotating rings 12 adapted to the slide 11 at the left and right ends of the connecting seat 13, and a rotating seat 28 sleeved on the outside of the rotating rings 12 and rotatably connected to the connecting seat 13.

[0049] Specifically, the outer sliding plate 9 is fixedly installed on the outside of the support base 6, and the inner sliding plate 10 is fixedly installed on the outside of the vertical rod 5. Slide tracks 11 are fixedly installed on the left and right sides of the outer sliding plate 9 and the inner sliding plate 10. Two rotating rings 12 are slidably installed inside the slide tracks 11. The connecting base 13 includes two fixedly connected sub-connecting bases, and each rotating ring 12 is axially rotatably mounted on a sub-connecting base. The sub-connecting bases have positioning holes 14. A connecting plate 16 is connected to the front of both sub-connecting bases. Positioning pins 15 are fixedly installed on both sides of the rear of the connecting plate 16 near the middle, and the positioning pins 15 are adaptively matched with the positioning holes 14. Anti-slip sleeves 17 are fixedly connected to the outside of the rotating rings 12. The anti-slip sleeves 17 ensure that the rotating rings 12 can rotate relative to the connecting base 13 within the slide tracks 11.

[0050] In this embodiment, threaded holes are provided at the four corners of the front part of the connecting plate 16 to fix it to the connecting seat 13. The surface of the anti-slip sleeve 17 is provided with anti-slip texture, and the sub-connecting seat is U-shaped. Before use, the sliding following structure 8 is placed inside the cavity formed by the support seat 6 and the outer slide plate 9, and the rotating rings 12 on both sides are slid into the slide rail 11 located at the front of the device. The line connecting the sub-connecting seats 13 on both sides is positioned perpendicular to the outer slide plate 9. The connecting plate 16 and the connecting seat 13 are connected through the positioning holes 14 and the positioning pins 15, and the connecting plate 16 and the sub-connecting seat 13 are fixed with fixing bolts to prevent the connecting plate 16 from falling off during sliding.

[0051] The secondary protection structure 23 inside the slide 11 includes a mounting base 24 placed between two rotating rings 12 and fixed to the connecting seat 13, and two sliding blocks 25 slidably connected to the mounting base 24, with a brake pad 26 fixed on each sliding block 25.

[0052] Specifically, a secondary protective structure 23 is provided between the outer sliding plate 9 and the inner sliding plate 10. The secondary protective structure 23 includes a mounting base 24 and a sliding block 25. The mounting base 24 is fixedly connected to the U-shaped notch of the sub-connecting seat. The two sliding blocks 25 are symmetrically slidably installed on the front and rear sides of the connecting seat 13. Brake pads 26 are fixedly connected to the opposite sides of the two sliding blocks 25. Protrusions 27 are fixedly installed at both ends of the sliding blocks 25.

[0053] The rotation and scaling mechanism is used to convert the rotation of the rotating seat 28 into the sliding of the two brake pads 26 along the front and back direction of the vertical rod 5;

[0054] When the operator climbs upwards and pulls the connecting seat 13 upwards via the rope assembly, the rotating ring 12 rotates counterclockwise within the slide rail 11, while the rotating seat 28 remains stationary and the two brake pads 26 retract towards the mounting seat 24. The operator ascends and descends from the front of the slide rail. As the operator climbs along the crossbar 4 towards the top of the device, the rope assembly pulls the connecting plate 16 along the outside of the outer slide plate 9 upwards, causing the rotating ring 12 inside the slide rail 11 to slide upwards towards the top of the device under the friction of the anti-slip sleeve 17.

[0055] When the operator falls, the connecting seat 13 moves down, causing the rotating ring 12 to rotate clockwise in the slide rail 11. The rotating seat 28 rotates clockwise, and the two brake pads 26 extend out of the mounting seat 24 and engage with the inner wall of the slide rail 11.

[0056] In a preferred embodiment of the present invention, the inner wall of the rotating ring 12 is provided with a ratchet groove 18, the outer surface of the rotating seat 28 is provided with a through groove 31, and a pawl 32 is elastically connected in the through groove 31. The pawl 32 can be engaged or disengaged from the ratchet groove 18 respectively. The ratchet groove 18 is provided on the close side of the two rotating rings 12. The rotating ring 12 is in the shape of a bottle cap and is fastened on the ratchet groove 18. The far side of the two rotating rings 12 can be rotated at the root of the hollow cylinder 34 by bearings or other common components.

[0057] The rotation of the rotating ring 12 enables the rotating seat 28 to rotate clockwise in one direction.

[0058] Preferably, the ratchet assembly also includes two hollow cylinders 34, two fixing posts 36, and two return disc springs 37 fixed on the connecting seat 13;

[0059] Each hollow cylinder 34 is supported by a rotating ring 12 and a rotating seat 28. The rotating seat 28 has a through hole 33, and the hollow cylinders 34 are fitted into the through holes 33 at intervals. A fixing post 36 is fixedly installed inside the hollow cylinder 34, and a reset disc spring 37 is wound around the outside of the fixing post 36.

[0060] One end of the reset disc spring 37 is fixedly installed on the outer surface of the fixed post 36, and the other end of the reset disc spring 37 passes through the hollow cylinder 34 and is connected to the inner wall of the through hole 33.

[0061] After the rotating seat 28 rotates, the reset disc spring 37 is stretched. When the operator needs to rotate the ring 12 counterclockwise again, the rotating seat 28 is reset under the elastic force of the reset disc spring 37, which drives the brake pad 26 to retract.

[0062] Specifically, the top and bottom of the rotating seat 28 are provided with through slots 31, and a pawl 32 is rotatably installed inside the through slot 31. Several ejection springs 35 are provided between the pawl 32 and the through slot 31. A through hole 33 is provided on the axis of the rotating seat 28. A hollow cylinder 34 is fixedly installed at one end of the connecting seat 13, and the hollow cylinder 34 is located inside the through hole 33. A fixing post 36 is fixedly installed on the axis of the hollow cylinder 34, and a return coil spring 37 is wound around the outside of the fixing post 36.

[0063] During the upward movement of the rotating ring 12, the rotating ring 12 will rotate counterclockwise. At this time, the ratchet groove 18 inside the rotating ring 12 will continuously squeeze the top arc surface of the pawl 32, so that the pawl 32 is always inside the through groove 31. Since the hollow cylinder 34 is fixedly connected to the connecting seat 13, under the elastic force of the return disc spring 37 inside the hollow cylinder 34, the rotating seat 28 will be in a stationary state. At this time, the brake pad 26 is in the retracted position and does not contact the inner wall of the outer slide plate 9 and the inner slide plate 10. With the connection of the rope component, the sliding following structure 8 can smoothly follow the operator to climb up along the device.

[0064] When an operator accidentally steps into a hole and falls, the rope component will cause the connecting plate 16 to slide towards the bottom of the device. Under the friction of the anti-slip sleeve 17, the rotating ring 12 will rotate clockwise along the slide 11. At this time, the ratchet groove 18 inside the rotating ring 12 will no longer press the top of the pawl 32. Under the elastic force of the ejector spring 35, the pawl 32 will be ejected, so that the inclined surface of one end of the pawl 32 will engage with the groove of the ratchet groove 18. At this time, as the rotating ring 12 rotates clockwise, the pawl 32 will drive the rotating seat 28 to rotate clockwise, which in turn will drive the rotating seat 28 to rotate clockwise. The brake pads 26 on both sides will contact the inner walls of the outer slide plate 9 and the inner slide plate 10, respectively. The greater the falling force, the greater the force of the brake pads 26 contacting the inner walls. Finally, the sliding follower structure 8 will stop moving through the secondary protection structure 23.

[0065] Preferably, the diameter of the through hole 33 is larger than the diameter of the hollow cylinder 34, one end of the ejector spring 35 is fixedly installed at the bottom of the through groove 31, and the other end of the ejector spring 35 is fixedly installed at the bottom of the pawl 32.

[0066] The diameter of the through hole 33 is larger than the diameter of the hollow cylinder 34. The reset disc spring 37 installed inside the hollow cylinder 34 will be in a stretched state when the control plate 29 rotates clockwise and drives the rotating seat 28 to rotate. After the operator readjusts his posture and gets out of danger, he pulls the connecting plate 16 through the rope component, which drives the rotating ring 12 to rotate counterclockwise. The rotating seat 28 will be reset under the elastic force of the reset disc spring 37, which will drive the brake pad 26 to retract, so that the sliding following structure 8 can follow the operator to move again.

[0067] Preferably, the top of the pawl 32 is arc-shaped, one end of the pawl 32 is beveled, and the pawl 32 is adaptively matched with the ratchet groove 18.

[0068] The top of the pawl 32 is arc-shaped, and one end of the pawl 32 is inclined. When the rotating ring 12 rotates counterclockwise, it will squeeze the top of the pawl 32, causing the pawl 32 to retract into the through groove 31. When the rotating ring 12 rotates clockwise, it will press against one end of the pawl 32 through the groove of the ratchet groove 18. The pawl 32 drives the rotating seat 28 to rotate clockwise, so that the brake pad 26 can be pushed out to contact the inner wall of the outer slide plate 9 and the inner slide plate 10, thereby protecting the operator.

[0069] In a preferred embodiment of the present invention, the rotation and scaling mechanism includes a protrusion 27 and a control plate 29;

[0070] Two protrusions 27 located radially on the rotating ring 12 are fixed on each side of the sliding block 25; the two sliding blocks 25 are symmetrically slidably installed on the front and rear sides of the connecting seat 13, and brake pads 26 are fixedly connected to the opposite sides of the two sliding blocks 25.

[0071] Control plates 29 are fixedly mounted on the adjacent sides of the two rotating seats 28. Two rotationally symmetrical arc-shaped grooves 30 are formed on the control plates 29. The arc-shaped grooves 30 are adaptively matched with the protrusions 27. The rotation of the rotating seats 28 drives the arc-shaped grooves 30 to drive the protrusions 27 to move radially linearly in the rotating ring 12. The rotation and scaling mechanism is prior art, for example, the invention patent application CN201910199793.7 entitled "A Tire Activated Module Synchronous Radial Telescopic Circle-Splitting Device and Circle-Splitting Implementation Method".

[0072] Specifically, control plates 29 are fixedly mounted on the adjacent sides of the two rotating seats 28. Arc-shaped grooves 30 are formed on both sides of the control plates 29, and these grooves 30 are adaptively matched with the protrusions 27. In this embodiment, the sum of the distance the two arc-shaped grooves 30 rotate, causing the brake pad 26 to move via the protrusions 27, and the length of the mounting base 24, is greater than the distance between the outer sliding plate 9 and the inner sliding plate 10. A lifespan groove is formed on the outside of the brake pad 26. The lifespan groove is used to indicate when the brake pad needs to be replaced.

[0073] The sum of the distance that the two arc-shaped grooves 30 rotate and the distance that the brake pads 26 move due to the protrusions 27, plus the length of the mounting base 24, is greater than the distance between the outer slide plate 9 and the inner slide plate 10. This ensures that the brake pads 26 can contact the inner walls of the outer slide plate 9 and the inner slide plate 10 during the clockwise rotation of the rotating base 28. The friction force prevents the operator from falling, and the greater the falling force, the greater the force applied to the brake pads 26, resulting in a greater friction force generated when the brake pads 26 contact the inner walls. The pawl 32 drives the rotating seat 28 to rotate clockwise, which in turn drives the control plate 29, which is fixedly connected to the rotating seat 28, to rotate clockwise. The arc-shaped groove 30 on the control plate 29 allows the protrusion 27 to move along the arc-shaped groove 30, causing the sliding blocks 25 on both sides to slide out, so that the brake pads 26 on both sides contact the inner walls of the outer sliding plate 9 and the inner sliding plate 10 respectively. Under the action of the control plate 29, the greater the falling force, the greater the force of the brake pads 26 contacting the inner walls. Finally, the secondary protection structure 23 stops the sliding follower structure 8 from moving.

[0074] In a preferred embodiment of the invention, since the sliding following structure 8 needs to move on the front and rear sides of the device, the rope component can be provided with an adjustable-length rope as needed. More preferably, a connecting plate 16 is fixed to the front side of the connecting seat 13, and an outer sliding plate 9 is fitted into the gap between the connecting seat 13 and the connecting plate 16. A second fixing hook 20 and a third fixing hook 21 are fixedly installed on the connecting plate 16. A first fixing hook 19, a second fixing hook 20, and a third fixing hook 21 are sequentially fixedly installed at the center of the front part of the connecting plate 16. A recovery rope is connected to the first fixing hook 19, a short safety rope is connected to the second fixing hook 20, and a long safety rope is installed on the third fixing hook 21.

[0075] The rope assembly includes a short safety rope connected to the second fixing hook 20 and a long safety rope longer than the short safety rope connected to the third fixing hook 21; the long and short safety ropes may be scalable ropes.

[0076] When the operator climbs up from the front of slide 11, a short safety rope connects the protective suit and the connecting seat 13; when the operator pushes the sliding following structure 8 to the rear of slide 11, a long safety rope connects the protective suit at the front of slide 11 to the connecting seat 13. Two types of ropes are used because the rope used when pushing the sliding following structure 8 to the rear of slide 11 wears out faster than the rope used at the front, allowing for timely replacement and cost savings.

[0077] In a preferred embodiment of the present invention, a lever 22 is provided on the outside of the connecting seat 13. The lever 22 is used by the operator to move the sliding follower structure 8 from the front to the rear at the top of the slide rail 11.

[0078] In a preferred embodiment of the present invention, a support structure 38 is provided between the two uprights 2 near the top position. The support structure 38 includes a round rod 39 that is horizontally and fixedly connected to the top ends of the two uprights 2. The round rod 39 is fixedly inserted through the vertical rod 5.

[0079] A rotating handle 40 is rotatably mounted on one end of the round rod 39 near the vertical rod 5. A toggle bar 41 is fixedly mounted on the outside of the rotating handle 40, and the toggle bar 41 is compatible with the lever 22. Rotating the toggle bar 41 can move the lever 22.

[0080] Preferably, the support structure 38 includes two rotating arms 43 that rotate with the two ends of the round rod 39, and a guard plate 44 fixed between the two rotating arms;

[0081] An angle adjustment mechanism connected to the round rod 39 allows the guard plate 44 to be used to abut against the operator's waist.

[0082] Preferably, the angle adjustment mechanism and the lever 22 are located on the left and right sides of the vertical rod 5, and it includes a fixed plate 45, a sliding sleeve 46, a toothed groove 51 and a toothed block 50;

[0083] The round rod 39 is fixedly installed with a fixing plate 45 that is fixed to the vertical rod 5;

[0084] A sliding sleeve 46 is movably installed at the other end of the round rod 39, and a connecting spring 47 abuts between the sliding sleeve 46 and the fixed plate 45. A positioning rod 49 is fixedly installed on the outside of the sliding sleeve 46. A groove 48 is opened on one side of the guard plate 44 near one end, and the groove 48 is compatible with the positioning rod 49. A toothed block 50 is fixedly installed at one end of the sliding sleeve 46. A toothed groove 51 is opened on the inner side of the top of the vertical rod 2 of the sliding sleeve 46, and the toothed groove 51 is compatible with the toothed block 50.

[0085] One end of the connecting spring 47 is connected to the fixed plate 45, and the other end of the connecting spring 47 is in contact with the other end of the sliding sleeve 46.

[0086] After the operator climbs to the top of the device, pulling the short safety rope causes the connecting seat 13 to continue moving to the top of the outer slide plate 9. By rotating the handle 40, the actuating rod 41 is rotated, and the actuating rod 41 actuates the lever 22, causing the sliding following structure 8 to move to the rear of the device. At this time, pulling the short safety rope causes the rotating ring 12 to rotate clockwise, causing the brake pad 26 to pop out and contact and fix with the inner wall of the outer slide plate 9 and the inner slide plate 10 at the rear of the device. The recovery rope connected to the first fixing hook 19 is then thrown down from the rear of the device. By pulling the sliding sleeve 46, the sliding sleeve 46 is compressed against the connecting spring 47, and the toothed block 50 fixedly installed at one end of the sliding sleeve 46 is disengaged from the toothed groove 51. The sliding sleeve 46 is rotated to adjust the position of the guard plate 44, so that the guard plate 44 contacts the waist of the operator. The sliding sleeve 46 is released, and the elastic force of the connecting spring 47 causes the toothed block 50 to re-insert into the toothed groove 51, fixing the position of the guard plate 44. This makes it convenient for the operator to carry out maintenance work at height, provides the operator with additional support points, and makes it easier to carry out photovoltaic equipment maintenance work.

[0087] In this embodiment, one end of the connecting spring 47 is connected to the fixing plate 45, and the other end of the connecting spring 47 is in contact with the other end of the sliding sleeve 46.

[0088] Under the elastic force of the connecting spring 47, the tooth block 50 can be made to come into close contact with the tooth groove 51, thereby fixing the position of the guard plate 44.

[0089] In a preferred embodiment of the present invention, a hook 7 is fixedly installed on the front side of the upright 2 near the top. The basic safety rope is connected to the operator's protective clothing via the hook 7, ensuring that the operator is connected to the upright 2 in the event of a fall. The basic safety rope serves as another protective measure for the operator, preventing them from falling from the upright 2 to the ground.

[0090] When using it, first move the climbing device to the area under the photovoltaic equipment that needs to be repaired, rotate the reinforcing pile at the bottom of the pole 2 to insert the reinforcing pile into the soil, and place the counterweight on the base plate 1. Then, connect the foundation safety rope to the operator's protective clothing through the hook 7.

[0091] A retrieval rope is connected to the first fixed hook 19, a short safety rope is connected to the second fixed hook 20, and a long safety rope is installed on the third fixed hook 21. The short and long safety ropes are connected to the operator's protective clothing respectively. As the operator climbs up the horizontal bar 4 to the top of the device, the short safety rope will pull the connecting plate 16 to slide along the outside of the outer slide plate 9 to the top of the device. This causes the rotating ring 12 inside the slide 11 to slide along the slide 11 to the top of the device under the friction of the anti-slip sleeve 17.

[0092] At this time, the rotating ring 12 will rotate counterclockwise under the friction of the anti-slip sleeve 17. The ratchet groove 18 inside the rotating ring 12 will continuously squeeze the top arc surface of the pressure plate 32, so that the pressure plate 32 is always inside the through groove 31. Since the hollow cylinder 34 is fixedly connected to the connecting seat 13, under the elastic force of the return disc spring 37 inside the hollow cylinder 34, the rotating seat 28 will be stationary. At this time, the protrusion 27 on the sliding block 25 will make the brake pad 26 retracted under the action of the arc groove 30 and not contact the inner wall of the outer slide plate 9 and the inner slide plate 10. With the connection of the short safety rope, the sliding following structure 8 can smoothly follow the operator to climb up along the device.

[0093] When an operator accidentally steps into a hole and falls, the short safety rope, connected to the second fixing hook 20, will cause the connecting plate 16 to slide towards the bottom of the device. Under the friction of the anti-slip sleeve 17, the rotating ring 12 will rotate clockwise along the slide rail 11. At this time, the ratchet groove 18 inside the rotating ring 12 begins to rotate clockwise. The pressure plate 32, under the elastic force of the ejection spring 35, is ejected, causing one end of the pressure plate 32 to engage with the groove of the ratchet groove 18. Under the clockwise rotation of the rotating ring 12, the pressure plate 32 will drive the rotating seat 28 to rotate clockwise synchronously, and simultaneously drive the rotating seat 28 to rotate. The control plate 29 of the fixed connection rotates clockwise, and the protrusion 27 moves along the arc groove 30 opened on the control plate 29, so that the sliding blocks 25 on both sides of the mounting base 24 slide out, so that the brake pads 26 at one end of the sliding block 25 contact the inner walls of the outer slide plate 9 and the inner slide plate 10 respectively. Under the action of friction, it begins to decelerate. Under the action of the control plate 29, the greater the falling force, the greater the force of the brake pads 26 contacting the inner wall, and the greater the friction. The sliding follower structure 8 stops moving through the secondary protection structure 23 to protect the operator. At this time, the reset disc spring 37 will be in a stretched state.

[0094] After the operator readjusts their posture and escapes danger, they pull the connecting plate 16 with the short safety rope, causing the rotating ring 12 to start rotating counterclockwise again. The rotating seat 28 will be reset under the elastic force of the reset disc spring 37, causing the brake pad 26 to retract, so that the sliding following structure 8 can follow the operator to rise again.

[0095] After the operator climbs to the top of the device, pulling the short safety rope causes the connecting seat 13 to continue moving to the top of the outer slide plate 9. By rotating the handle 40, the actuating rod 41 is rotated, and the actuating rod 41 actuates the lever 22, causing the sliding following structure 8 to move into the slide rail 11 at the rear of the device. Pulling the short safety rope again causes the rotating ring 12 to rotate clockwise, causing the brake pad 26 to pop out and contact and fix with the inner wall of the outer slide plate 9 and the inner slide plate 10 at the rear of the device, thus connecting the first fixing hook 19. The recovery rope is thrown down from the rear of the device. By pulling the sliding sleeve 46, the sliding sleeve 46 is squeezed against the connecting spring 47, and the toothed block 50 fixedly installed at one end of the sliding sleeve 46 is disengaged from the toothed groove 51. The sliding sleeve 46 is rotated to adjust the position of the guard plate 44 so that the guard plate 44 contacts the waist of the operator. The sliding sleeve 46 is released, and the elastic force of the connecting spring 47 causes the toothed block 50 to re-insert into the toothed groove 51, fixing the position of the guard plate 44. The operator can use the support points of the legs and waist to perform photovoltaic equipment maintenance work.

[0096] After the operator completes the maintenance task, pull the sliding sleeve 46 again to adjust the guard plate 44 to the horizontal position. Then, release the short safety rope from the second fixing hook 20 and return along the device under the protection of the long safety rope and the third fixing hook 21. At this time, due to the pulling effect of the long safety rope, there is always a tendency to drive the rotating ring 12 to rotate clockwise, and the brake pad 26 will always be in the pop-out state to provide secondary protection for the operator.

[0097] After the operator returns to the ground, they first unsecure the long safety rope from their protective suit, then move to the back of the device and pull the retrieval rope. Under the pull of the retrieval rope, the connecting plate 16 will slide down the outer slide plate 9 at the back of the device, causing the rotating ring 12 to start rotating counterclockwise. Under the elastic force of the reset disc spring 37, the brake pad 26 will retract and reset, allowing the sliding follower structure 8 to smoothly return to the bottom of the outer slide plate 9. By removing the connecting plate 16 and adjusting the position of the connecting seat 13, the retrieval of the sliding follower structure 8 and the secondary protective structure 23 is completed.

[0098] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
