Description

Technical Field

[0001] This utility model relates to the field of maintenance lifeline, specifically a photovoltaic maintenance lifeline for sewage treatment plants. Background Technology

[0002] Photovoltaic operation and maintenance lifeline usually refers to the rope or rope system used to ensure the safety of workers in the operation and maintenance of photovoltaic power plants. During the operation and maintenance of photovoltaic power plants, workers may need to carry out inspection and maintenance work in high-altitude work areas such as rooftops and supports. Therefore, ensuring safety is very important. When in use, steel cables are installed on the roof, and then when the user is carrying out inspection and maintenance, the safety rope and shuttle are secured to the steel cables.

[0003] The existing safety ropes and shuttles are usually tied directly to the bottom of the shuttle. With prolonged use, the safety rope will become tighter and tighter. During long-term use and transportation, the safety rope may wear down. The safety factor of the worn safety rope is reduced, and the safety rope needs to be replaced. It is difficult to disconnect the connection during replacement, so scissors or knives are needed to cut it, which is quite troublesome. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a lifeline for the operation and maintenance of photovoltaic systems in sewage treatment plants, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifeline for photovoltaic operation and maintenance in a sewage treatment plant, comprising a shuttle body, a fixing plate fixed to one side of the shuttle body, and two sets of fixing rods fixed to one side of the fixing plate, a clamping plate movably installed at the end of the fixing rod, and a horizontal plate fixed to one side of the clamping plate, two sets of limiting plates fixed to one side of the fixing plate, and two sets of rotating rods movably installed to one side of the clamping plate, with threads on the outer wall of the rotating rods, a threaded groove opened inside the fixing rods, and a safety rope provided on the outer wall of the fixing rods, the safety rope being wrapped in a figure-eight pattern around the outer wall of the fixing rods.

[0006] By adopting the above technical solution, the problem of the existing safety rope being inconvenient to disassemble is solved. The safety rope is wrapped around the outside of the two sets of fixed poles in a figure-eight wrapping method. Tightening the safety rope and wrapping it three times can increase the friction between the safety rope and the fixed pole, thus making it less likely for the safety rope to fall off the fixed pole.

[0007] The present invention is further configured such that a vertical groove is provided on one side of the fixing plate, and a pressing block is fixed on one side of the clamping plate.

[0008] Preferably, the end of the safety rope enters the vertical groove. When the clamping plate approaches the fixing plate, the squeezing block will squeeze the safety rope, thereby preventing the safety rope from moving.

[0009] The present invention is further configured such that the outer wall of the extrusion block has multiple sets of built-in grooves.

[0010] Preferably, the built-in groove increases the contact area between the compression block and the safety rope, thus preventing the end of the safety rope from moving easily.

[0011] The present invention is further configured such that the outer wall of the limiting plate is provided with a first groove, the outer wall of the horizontal plate is provided with a second groove, and the horizontal plate and the limiting plate are arranged alternately.

[0012] Preferably, the first and second grooves can be used to conveniently limit the safety rope and prevent it from moving left or right. The staggered horizontal plates and limiting plates can better limit the safety rope and prevent it from becoming loose.

[0013] The present invention is further configured such that the fixing plate, the clamping plate, the fixing rod, the horizontal plate and the limiting plate are all made of metal.

[0014] Preferably, the fixing plate, clamping plate, fixing rod, cross plate and limiting plate are made of metal, which makes them less prone to deformation during use.

[0015] The present invention is further configured such that a handle is fixed to the end of the rotating rod.

[0016] Preferably, the rotating handle allows personnel to easily rotate the rotating rod, and the arc-shaped end of the rotating rod facilitates its entry into the threaded groove.

[0017] In summary, the present invention has the following main advantages: This invention solves the problem of existing safety ropes being difficult to disassemble by incorporating a fixing plate, a clamping plate, a rotating rod, and a fixing rod. By wrapping the safety rope around the outside of the two sets of fixing rods in a figure-eight manner and tightening the safety rope by wrapping it three times, the friction between the safety rope and the fixing rod can be increased, thus making it less likely for the safety rope to detach from the fixing rod.

[0018] This utility model features a limiting plate, a first groove, a horizontal plate, and a second groove. The end of the safety rope is located inside the vertical groove and is under tension. When the clamping plate is installed, the rotating rod is inserted into the threaded groove and then tightened, causing the clamping plate to be in close contact with the limiting plate. At this time, the horizontal plate enters between the two sets of limiting plates, and the horizontal plate and limiting plate tightly press the safety rope against the fixing plate and the clamping plate. The pressing block also presses the end of the safety rope into the vertical groove. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Please see Figures 1-4 The system includes a shuttle body 1, a fixing plate 2 fixed on one side of the shuttle body 1, and two sets of fixing rods 6 fixed on one side of the fixing plate 2. A clamping plate 3 is movably installed at the end of the fixing rod 6, and a horizontal plate 31 is fixed on one side of the clamping plate 3. Two sets of limiting plates 21 are fixed on one side of the fixing plate 2. Two sets of rotating rods 5 are movably installed on one side of the clamping plate 3, and the outer wall of the rotating rod 5 is provided with threads 51. The inside of the fixing rod 6 is provided with threaded grooves 61. A safety rope 7 is provided on the outer wall of the fixing rod 6. The safety rope 7 is wrapped in a figure-eight pattern on the outer wall of the fixing rod 6. The figure-eight winding method of the safety rope 7 can make the safety rope 7 more stable and allow the fixing rod 6 to better limit the safety rope 7.

[0024] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 4 A vertical groove 23 is provided on one side of the fixing plate 2, and a squeezing block 4 is fixed on one side of the clamping plate 3. The end of the safety rope 7 enters the vertical groove 23. When the clamping plate 3 is close to the fixing plate 2, the squeezing block 4 will squeeze the safety rope 7, so that the safety rope 7 will not move.

[0025] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The outer wall of the extrusion block 4 has multiple sets of built-in grooves 41. The built-in grooves 41 can increase the contact area between the extrusion block 4 and the safety rope 7, so that the end of the safety rope 7 will not move easily.

[0026] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 4 The outer wall of the limiting plate 21 is provided with a first groove 22, and the outer wall of the horizontal plate 31 is provided with a second groove 32. The horizontal plate 31 and the limiting plate 21 are staggered. The first groove 22 and the second groove 32 can be used to limit the safety rope 7 and prevent the safety rope 7 from moving left and right. The staggered horizontal plate 31 and the limiting plate 21 can better limit the safety rope 7 and prevent the safety rope 7 from loosening.

[0027] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2 The fixing plate 2, clamping plate 3, fixing rod 6, horizontal plate 31 and limiting plate 21 are all made of metal. The metal material of the fixing plate 2, clamping plate 3, fixing rod 6, horizontal plate 31 and limiting plate 21 makes them less prone to deformation during use.

[0028] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 4 The end of the rotating rod 5 is fixed with a handle 52, and the end of the rotating rod 5 is arc-shaped. The handle 52 allows the operator to easily rotate the rotating rod 5, and the arc-shaped end of the rotating rod 5 allows it to easily enter the threaded groove 61.

[0029] In practical operation, the safety rope 7 is placed inside the vertical groove 23, ensuring it is not lower than the bottom of the fixing plate 2. The safety rope 7 is then wrapped around the outside of the two sets of fixing rods 6 in a figure-eight pattern. Tightening the rope 7 by wrapping it three times increases the friction between the rope 7 and the fixing rods 6, preventing it from easily detaching. The safety rope 7 is then placed inside the first groove 22. Next, the end of the rotating rod 5 is inserted into the inner wall of the threaded groove 61. At this point, the pressing block 4 and the horizontal plate 31 on one side of the clamping plate 3 are in contact with the safety rope 7, tightening the tension. Then, rotate the rotating rod 5 simultaneously. The external thread 51 of the rotating rod 5 engages with the thread groove 61. According to the screw principle, the simultaneous rotation of the two sets of rotating rods 5 will bring the clamping plate 3 and the fixing plate 2 closer together. At this time, the squeezing block 4 tightly presses the safety rope 7, and the horizontal plate 31 enters between the two sets of limiting plates 21. Both the horizontal plate 31 and the limiting plate 21 squeeze the safety rope 7. When the safety rope 7 is tightened, it will not easily fall off the fixing rod 6. The end of the squeezing block 4 squeezes one end of the safety rope 7, and the horizontal plate and the limiting plate 21 squeeze the other end of the safety rope 7 to ensure that the safety rope 7 will not easily loosen during use.
