Description

Technical Field

[0001] This invention relates to the field of steep slope protection technology, and in particular to a steep slope protection device for photovoltaic field operations. Background Technology

[0002] Steep slopes are typically convenient for installing photovoltaic panels because the bracket angle can be adjusted to fit the slope, maximizing the use of unused hillside space. Furthermore, some steep slopes are more likely to align with the optimal angle for solar radiation, improving power generation efficiency. Work on steep slopes involves clearing the slope, excavating and pouring foundations for the brackets, transporting and installing the photovoltaic panels and brackets, laying and connecting cables, checking the stability of the brackets, calibrating the panel angles, and subsequent cleaning and maintenance. Fall protection and anti-slip measures are required throughout the entire process. Currently, fall arrestors and ropes are typically used directly. However, workers often work in different locations, requiring them to climb to the rope installation point to unlock it and proceed to other locations. This process is complex and impractical. Therefore, designing a protective device that allows workers to work safely, stably, and conveniently on steep slopes is a problem that needs to be solved by those in the field. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a protective device for working on steep slopes in photovoltaic fields, enabling workers to operate safely, stably, and conveniently on steep slopes.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a protective device for steep slope operations in photovoltaic fields, comprising: A steel cable fixing assembly includes two installation components that can be vertically installed on a pile foundation or the ground, with a first steel cable and a second steel cable arranged horizontally and vertically between the two installation components; Two traveling components are slidably disposed between the first and second steel cables, and the traveling components include: The frame has a first traveling wheel that is rotatably mounted on it, and the first traveling wheel slides in contact with the top of the first steel cable; Two second travel wheels are rotatably and laterally arranged on both sides of the second steel cable, and the second travel wheels are in sliding contact with the second steel cable; The limiting components are in the form of two and are respectively located at the corresponding first and second travel wheels of the frame. The moving ends of the limiting components are respectively provided with a first pull rope and a second pull rope. When the first and second pull ropes are pulled downward, they can drive the corresponding limiting components to work and cause the limiting components to brake the corresponding first or second travel wheel. The safety ropes are two in number and are respectively connected to the first pull rope and the second pull rope of each of the two limiting components; The cable reel-in / reel-out assembly consists of two components arranged opposite each other on the safety rope. The cable reel-in / reel-out assembly can adjust the extension / retraction length of the safety rope at the corresponding position and can also limit its position after adjustment. A propulsion assembly is disposed between the two traveling assemblies, which, when in operation, can drive one of the traveling assemblies not braked by the limiting assembly to slide on the first and second cables.

[0005] Furthermore, the limiting component includes a gear coaxially mounted on the first or second travel wheel, a mounting sleeve is provided on the frame, an adjusting frame is slidably mounted on the mounting sleeve, a limiting pin is provided on the adjusting frame, and the adjusting frame is connected to the corresponding first or second pull rope. The inner side of the mounting sleeve is provided with a tension spring connected to the adjustment frame, which is used to pull the adjustment frame to reset it.

[0006] Furthermore, the take-up and release assembly includes a fall arrestor, the take-up and release end of the take-up and release assembly is connected to a safety rope, and a suspension rope is provided on the side of the take-up and release assembly away from the safety rope.

[0007] Furthermore, the propulsion assembly includes adjusting rods hinged to the top of the two corresponding frames, the two adjusting rods being hinged to each other, and torsion springs being provided at the connection points between the two adjusting rods and the corresponding frames. A connecting shaft is rotatably provided at the hinge points of the two adjusting rods, and a downwardly hanging adjusting rope is provided on the connecting shaft.

[0008] Furthermore, the steel cable fixing assembly includes a fixing pile, a first mounting rod is horizontally arranged on the side wall of the fixing pile, and a second mounting rod is vertically arranged on the side of the first mounting rod away from the fixing pile. The first steel cable and the second steel cable are respectively mounted on the top and bottom of the second mounting rod. The frame has an open section on the side facing the fixed pile, which is used to offset the first mounting rod when the traveling component travels to coincide with the cable fixing component.

[0009] Furthermore, the frame is equipped with an anti-detachment component, which can block the open parts of the frame when the frame does not overlap with the steel cable fixing component.

[0010] Furthermore, the anti-detachment component includes a storage sleeve disposed on the side of the frame near the fixed stake, and an anti-detachment plate is rotatably disposed on the frame, with the storage sleeve and the anti-detachment plate respectively located on both sides of the corresponding open portion of the frame; A torsion spring is provided at the connection between the anti-detachment plate and the frame, which is used to rotate the anti-detachment plate into the storage sleeve.

[0011] Furthermore, a magnet is provided on the inner wall of the storage sleeve, which can magnetically attract the anti-detachment piece when it rotates into the storage sleeve.

[0012] The beneficial effects of this invention are reflected in: This invention allows workers to attach ropes to the side of two take-up and release assemblies furthest from the safety rope. When working in place, the two take-up and release assemblies are adjusted so that each safety rope is taken up or released to a suitable height and then locked. The worker's own weight acts on the safety rope, causing the locking assembly to activate and all travel assemblies to be braked, thus facilitating work at the corresponding position. When moving to another position, the locking state of the corresponding take-up and release assembly can be released according to the direction of travel. At this time, the corresponding safety rope can be stretched and the corresponding first and second pull ropes can be released. The corresponding locking assembly then releases the lock on the first and second travel wheels. The worker can then operate the propulsion assembly to move the travel assembly on the steel cable fixing assembly. After the movement is complete, the travel assembly is braked again, and the brake on the other travel assembly is released. By repeating the above operation, stable travel adjustment can be achieved, ensuring that workers can work safely, stably, and conveniently on steep slopes. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-7 This invention discloses a protective device for steep slope operations in photovoltaic fields, including a steel cable fixing assembly 1, which includes two installation assemblies that can be vertically installed on pile foundations or the ground. A first steel cable 104 and a second steel cable 105 are horizontally arranged between the two installation assemblies and are distributed vertically. Two horizontally distributed traveling assemblies 2 are slidably arranged between the first steel cable 104 and the second steel cable 105. In use, the two traveling assemblies 2 can slide within the setting range of the first steel cable 104 and the second steel cable 105, thereby changing the working range of the workers.

[0017] In one embodiment, the traveling component 2 includes a frame 201, on which a first traveling wheel 202 is rotatably mounted. The first traveling wheel 202 slides in contact with the top of the first steel cable 104. Two second traveling wheels 203 are also rotatably mounted on the frame 201. The two second traveling wheels 203 are rotatably and laterally distributed on both sides of the second steel cable 105, and slide in contact with the second steel cable 105. Limiting components are provided at the corresponding positions of the first traveling wheel 202 and the second traveling wheel 203 on the frame 201. A first pull rope 208 and a second pull rope 209 are respectively provided at the moving ends of the corresponding limiting components. When the first pull rope 208 and the second pull rope 209 are pulled downward, they can drive the corresponding limiting components to work and cause the limiting components to brake the corresponding first traveling wheel 202 or the second traveling wheel 203.

[0018] Safety ropes 3 are provided on the side of each first pull rope 208 and second pull rope 209 of the two limiting components away from the corresponding limiting components, and a take-up and release assembly 4 is provided on the end of each safety rope 3 away from the traveling component 2. The take-up and release assembly 4 can adjust the extension length of the safety rope 3 at the corresponding position, and can also limit it after adjustment. A propulsion assembly 5 is provided between the two traveling components 2. When working, the propulsion assembly 5 can drive one of the traveling components 2 that is not braked by the limiting components to slide on the first steel cable 104 and the second steel cable 105.

[0019] In practice, workers can attach ropes to the side of the two take-up and release components 4 away from the safety rope 3. When working in place, the two take-up and release components 4 are adjusted so that each safety rope 3 is taken up or released to a suitable height and then limited. The worker's own weight acts on the safety rope 3, thereby activating the limiting components and putting each traveling component 2 in a braking state, thus facilitating work at the corresponding position. When it is necessary to travel to other positions, the locking state of the corresponding take-up and release component 4 can be released according to the direction of travel. At this time, the corresponding safety rope 3 can be stretched and the corresponding first pull rope 208 and second pull rope 209 can be released. At this time, the corresponding limiting components release the limitation on the first traveling wheel 202 and the second traveling wheel 203. The worker then operates the propulsion component 5 to push the traveling component 2 to move on the steel cable fixing component 1. After the movement is completed, the traveling component 2 is braked again, and the brake on the other traveling component 2 is released. By repeating the above operation, stable travel adjustment can be achieved.

[0020] It should be noted that after the cable reeling assembly 4 extends the safety rope 3 to a suitable length, the worker can also manually pull the safety rope 3 downwards, or adjust their own center and use their own weight to straighten the corresponding safety rope 3, thereby achieving the effect of temporary limiting.

[0021] In one embodiment, the limiting component includes a gear 204 coaxially mounted on the first travel wheel 202 or the second travel wheel 203. A mounting sleeve 205 is mounted on the frame 201, and an adjusting frame 206 is slidably mounted on the mounting sleeve 205. A limiting pin 207 is mounted on the adjusting frame 206, and the corresponding adjusting frame 206 is connected to the corresponding first pull rope 208 or second pull rope 209. In addition, a tension spring (not shown in the figure) connected to the adjusting frame 206 is mounted on the inner side of the mounting sleeve 205. The tension spring is used to pull the adjusting frame 206 to reset it.

[0022] In practice, when the corresponding safety rope 3 is pulled downward, it will drive the corresponding first pull rope 208 and second pull rope 209 to move synchronously. At this time, the adjusting frame 206 will move to the side closer to the corresponding gear 204 and drive the limiting pin 207 to be inserted into the tooth groove of the gear 204, thereby locking the gear 204. Therefore, the corresponding first travel wheel 202 or second travel wheel 203 can be braked.

[0023] In practice, anti-slip grooves can be formed on both the first traveling wheel 202 and the second traveling wheel 203. These anti-slip grooves are in contact with the first steel cable 104 and the second steel cable 105. Therefore, when the first traveling wheel 202 or the second traveling wheel 203 brakes, the friction between it and the first steel cable 104 and the second steel cable 105 can be further increased, thereby improving the braking effect. In addition, a protective shell is provided on the outside of the limiting component. This protective shell is installed on the frame 201 for protection.

[0024] In one embodiment, the take-up and release assembly 4 includes a fall arrestor, the take-up and release end of the take-up and release assembly 4 is connected to the safety rope 3, and a suspension rope is provided on the side of the take-up and release assembly 4 away from the safety rope 3. With this design, the fall arrestor has a speed difference fall arrest function, which can effectively ensure the safety of the staff when the safety rope 3 is being raised and lowered. The fall arrestor mentioned above is common knowledge in this field, so its specific structural composition and working principle will not be described in detail in this article.

[0025] In one embodiment, the propulsion assembly 5 includes an adjustment rod 501 hinged to the top of two corresponding frames 201. The two adjustment rods 501 are hinged to each other, and a torsion spring is provided at the connection between the two adjustment rods 501 and the corresponding frame 201. A connecting shaft 502 is rotatably mounted at the hinge of the two adjustment rods 501, and an adjustment rope 503 hanging down is provided on the connecting shaft 502.

[0026] In practice, the length of the adjusting rope 503 is adapted to the maximum extension length of the worker and the safety rope 3 to facilitate the worker's operation. When the adjusting rope 503 is pulled down by the worker, it drives the two adjusting rods 501 to rotate downward with their connection point as the center. At this time, the traveling component 2, which is not in the limit state, moves accordingly. After the adjusting rope 503 is released, the torsion spring drives the two adjusting rods 501 to reset, ready for the next operation and adjustment.

[0027] In one embodiment, the cable fixing assembly 1 includes a fixing post 101, a first mounting rod 102 is horizontally mounted on the side wall of the fixing post 101, and a second mounting rod 103 is vertically mounted on the side of the first mounting rod 102 away from the fixing post 101. A first steel cable 104 and a second steel cable 105 are respectively mounted on the top and bottom of the second mounting rod 103. The frame 201 has an open portion on the side facing the fixing post 101, which is used to offset the first mounting rod 102 when the traveling assembly 2 travels to coincide with the cable fixing assembly 1.

[0028] In practice, staff can set up a corresponding number of fixed stakes 101 according to the actual situation, so as to flexibly configure the setting length of the first steel cable 104 and the second steel cable 105, so as to improve the working range of staff. When the traveling component 2 travels to coincide with the steel cable fixing component 1, the open part of the frame 201 is offset from the first mounting rod 102, so that it can effectively cross the fixed stake 101. Therefore, staff do not need to climb up to manually cross it, thus effectively improving the convenience of operation.

[0029] In addition, a ground-inserting cone can be installed at the bottom of the fixed pile 101. In the absence of a foundation pile, the ground-inserting cone can be driven into the ground, so that the fixed pile 101 can be fixed on the ground. The aforementioned ground-inserting cone is common knowledge in the field, so its specific structural composition and working principle will not be described in detail in this article.

[0030] In practice, the frame 201 is equipped with an anti-detachment component 6, which can block the open part of the frame 201 when the frame 201 does not overlap with the steel cable fixing component 1.

[0031] With this design, when the worker is in operation, the open part of the traveling component 2 is blocked by the anti-detachment component 6, thereby effectively preventing the traveling component 2 from separating from the first steel cable 104 and the second steel cable 105, thus ensuring the safety of the worker.

[0032] In one embodiment, the anti-detachment component 6 includes a storage sleeve 601 installed on the side of the frame 201 near the fixed post 101. The storage sleeve 601 is U-shaped. An anti-detachment plate 602 is rotatably installed on the frame 201. The storage sleeve 601 and the anti-detachment plate 602 are located on both sides of the frame 201 corresponding to its open portion. A torsion spring is provided at the connection between the anti-detachment plate 602 and the frame 201. The torsion spring is used to drive the anti-detachment plate 602 to rotate into the storage sleeve 601.

[0033] In practice, when the frame 201 travels to coincide with the first mounting rod 102, the first mounting rod 102 will squeeze the anti-detachment plate 602 to rotate. At this time, the frame 201 can continue to travel. When it rotates to the point of being misaligned and separated from the first mounting rod 102, the torsion spring drives the anti-detachment plate 602 to reset, thereby providing continuous protection.

[0034] In one embodiment, a magnet (not shown) is installed on the inner wall of the storage sleeve 601, which is magnetically attracted to the anti-detachment piece 602 when it rotates into the storage sleeve 601.

[0035] With this design, when the worker is in operation, the magnet will magnetically attract the anti-detachment piece 602, which can further improve the connection stability at that point. In addition, a non-slip layer can be configured inside the storage sleeve 601. This layer can be a rubber layer, thereby increasing the friction with the anti-detachment piece 602 and preventing the anti-detachment piece 602 from falling out of the storage sleeve 601 without reason when no adjustment is needed.

[0036] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0037] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0038] Additionally, "multiple" refers to two or more.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
