Description

Technical Field

[0001] The present application belongs to the technical field of electric line towers, and specifically relates to overhead collector line towers for high-altitude wind farms. Background Art

[0002] High-altitude areas experience unique meteorological conditions, such as high wind speeds and severe icing. Towers require superior mechanical strength to withstand significant wind and ice loads. Because air density is lower at high altitudes, wind load calculations must be adjusted based on actual air density and other meteorological parameters to ensure tower stability in strong winds. For icing conditions, the additional pressure exerted by the weight of the ice on the tower structure must be considered. Design efforts should increase the tower's load-bearing capacity, for example by increasing the cross-sectional dimensions of the tower members or using higher-strength materials.

[0003] For example, patent number CN219733286U discloses a high-altitude wind farm overhead power line tower, comprising a tower body, a maintenance ladder provided on the side end face of the tower body, a heating wire provided inside the maintenance ladder, a wind turbine blade provided on the top of the tower body, a wind turbine generator and a lithium battery provided inside the tower body, the wind turbine blade and the wind turbine generator being connected via a reducer, the wind turbine generator and the lithium battery being electrically connected via a rectifier, and a heating switch provided on the front face of the tower body. This utility model heats the maintenance ladder via the heating wire, melting frost on its surface and preventing slipping when climbing the ladder. It also improves the grip feel and heats the palms, facilitating subsequent maintenance work. Power is supplied by the wind turbine generator and the lithium battery, preventing line failures that would prevent the heating wire from being able to heat up in time, thereby improving the stability and environmental performance of the equipment.

[0004] During the use of this device, the following problems were discovered with this technology: The device uses a lithium battery connected to a heating wire to heat the maintenance ladder, melting the frost on its surface and making it easier for workers to climb. However, when climbing, workers generally need to carry work items such as equipment parts and maintenance tools. This makes climbing not only very heavy and inconvenient, but also dangerous, which is detrimental to worker safety. Therefore, to solve this problem, it is necessary to propose an overhead collector line tower for high-altitude wind farms. Utility Model Content

[0007] Sprockets are rotatably mounted on the top and bottom ends of the fixed rod, and chains fixed to two climbing plates respectively are wound around the two sprockets. A counterweight box is fixedly mounted on the outer wall of the climbing plate on the left track plate, and an oil barrel is fixedly mounted inside the base plate. An oil pump is fixedly mounted on the top of the oil barrel, and an oil delivery hose is fixedly connected to the end of the oil pump. The top end of the oil delivery hose is connected to the counterweight box, and the oil barrel is filled with antifreeze synthetic oil.

[0008] In a preferred embodiment, a limiting sliding groove adapted to the climbing plate is provided on the outer side of the track plate, and limiting portions sliding in the limiting sliding groove are provided on both sides of the sliding end of the climbing plate.

[0009] In a preferred embodiment, a through slot for the lifting basket to pass through is opened on the right side of the workbench, a fence sliding door is provided on the outside of the lifting basket, and the opening and closing power of the fence sliding door comes from an electric push rod provided in the lifting basket.

[0010] In a preferred embodiment, a movable groove adapted to the movable rod is provided in the end portion of the damper, and a No. 1 return spring is sleeved and installed on the outer periphery of one end of the movable rod located in the damper.

[0011] In a preferred embodiment, a damping cylinder extending outward is fixedly installed inside the damper, and a hydraulic chamber and a nitrogen chamber are respectively opened on both sides of the interior of the damping cylinder.

The chamber in the hydraulic chamber to the right of the No. 1 piston is filled with hydraulic oil, and the chamber in the nitrogen chamber to the right of the No. 2 piston is filled with nitrogen.

[0012] In a preferred embodiment, a large-pore flow channel and a small-pore flow channel are respectively opened in the inner center and on both sides of the splitter. The left end of the large-pore flow channel is fixedly connected to a sealing plug through a No. 2 return spring, and the right side of the sealing plug is attached to the left side of the large-pore flow channel.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] In the present application, by setting the relevant structure on the climbing plate, when the climbing plate moves on the track plate, the rack on the track plate will mesh with the gear rod to drive the turntables on both sides of the climbing plate to rotate. At this time, the arc-surface protrusions on the outer periphery of the rotating turntable will squeeze the roller during the circumferential movement, driving the movable rod to compress the No. 1 return spring inside the damper to move. At the same time, when the arc-surface protrusion passes over the roller, the roller loses the abutment of the arc-surface protrusion. At this time, under the rebound of the No. 1 return spring, the movable rod will return to its original position. In the process of the movable rod moving into and returning to the inside of the damper, the movable rod will drive the No. 1 piston to move in the hydraulic chamber to create positive and negative pressure in the hydraulic chamber. When the movable rod pushes the No. 1 piston to move toward the hydraulic chamber, the pressure in the hydraulic chamber The hydraulic oil will be transported to the nitrogen chamber through the splitter. At this time, since two flow channels are opened in the splitter, namely the large-hole flow channel and the small-hole flow channel, and the left side of the large-hole flow channel is connected to a sealing plug through the No. 2 return spring, which fits on the left side of the large-hole flow channel to close the flow channel, the hydraulic oil can only be discharged into the nitrogen chamber through the small-hole flow channel. At this time, the flow rate of the hydraulic oil is greatly restricted and can only pass through slowly. When the hydraulic oil reaches the nitrogen chamber, it will squeeze and drive the No. 2 piston to compress the nitrogen on its right side. When the roller loses the abutment of the arc-surface convex block, the No. 1 return spring on the periphery of the movable rod and the compressed nitrogen in the nitrogen chamber will rebound, causing the hydraulic oil just discharged into the nitrogen chamber to flow back through the splitter and return to the hydraulic chamber. At this time, the sealing plug on the left side of the large-hole flow channel will be reversed. The hydraulic oil flowing in the opposite direction is impacted and opened, so that the hydraulic oil flowing in the opposite direction can quickly return to the hydraulic chamber through the large-hole flow channel and the small-hole flow channel respectively. Based on the above principle, when the turntable rotates by squeezing the roller to make way through the arc-surface convex block, the speed at which the roller drives the movable rod to move into the damper to make way will be damped, so that it will limit the rotation speed of the turntable, thereby avoiding high-speed rotation of the turntable, thereby making the gear rod can only rotate slowly under the engagement of the rack, so that the climbing plate can only rise or fall slowly on the track plate. Based on the damping function that the climbing plate can only rise or fall slowly on the track plate, when the staff needs to carry items to the top of the tower, they can first start the oil pump to pump the antifreeze synthetic oil in the counterweight box into In the oil barrel, the weight of the lifting basket is higher than the counterweight box at this time. Under the circuit control of the sprocket and chain, the lifting basket will slowly descend to the top position of the base plate, and the counterweight box will rise to the top at this time. Then the staff will carry the items to the inside of the lifting basket and start the oil pump to pump the antifreeze synthetic oil in the oil barrel into the counterweight box. At this time, the weight of the counterweight box is greater than the total weight of the lifting basket and the staff and items in the lifting basket, so that the counterweight box descends through the chain and sprocket to slowly lift the lifting basket to the position of the workbench above the pole tower, thereby completing the function of assisting the staff and items to climb and descend on the pole tower. At the same time, since the climbing and descending speed of the lifting basket is controlled, it can ensure the lifting safety of the staff in this process. BRIEF DESCRIPTION OF THE DRAWINGS

A bracket 10 is fixedly installed on the outside of the right climbing plate 6, and a lifting basket 11 is fixedly installed on the top of the bracket 10. A through slot for the lifting basket 11 to pass through is provided on the right side of the workbench 3. A fence sliding door is provided on the outside of the lifting basket 11, and the opening and closing power of the fence sliding door comes from the electric push rod provided in the lifting basket 11. The front and rear sides of the climbing plate 6 are rotatably installed with a turntable 12 fixedly connected to the two ends of the gear rod 9 through bearings. The outer periphery of the turntable 12 is provided with an arc-shaped protrusion 13, and the outer wall of the climbing plate 6 surrounds the turntable 12. The upper and lower sides are fixedly installed with dampers 14, and a movable rod 15 is slidably installed on one end of the damper 14 close to the turntable 12. A roller 16 is rotatably installed on the end of the movable rod 15 close to the turntable 12. A movable groove adapted to the movable rod 15 is provided in the end of the damper 14. A No. 1 return spring is installed on the outer periphery of one end of the movable rod 15 located in the damper 14. A damping cylinder 17 extending outward is fixedly installed inside the damper 14. A hydraulic chamber 18 and a nitrogen chamber 19 are respectively provided on both sides of the interior of the damping cylinder 17. The middle part of the damping cylinder 17 is fixedly installed with two ends respectively connected to the hydraulic chamber 18. The splitter 20 is connected to the nitrogen chamber 19, and a piston No. 1 21 and a piston No. 2 22 are respectively slidably installed in the hydraulic chamber 18 and the nitrogen chamber 19. The No. 1 piston 21 is fixedly connected to the movable rod 15. The chamber on the right side of the No. 1 piston 21 in the hydraulic chamber 18 is filled with hydraulic oil, and the chamber on the right side of the No. 2 piston 22 in the nitrogen chamber 19 is filled with nitrogen. A large-pore flow channel 23 and a small-pore flow channel 25 are respectively provided in the inner center and on both sides of the splitter 20. The left end of the large-pore flow channel 23 is fixedly connected to a sealing plug 24 through a No. 2 return spring, and the right side of the sealing plug 24 is attached to the left side of the large-pore flow channel 23.

[0023] By setting the relevant structure on the climbing plate 6, when the climbing plate 6 moves on the track plate 5, the rack 8 on the track plate 5 will engage the gear rod 9 to drive the turntables 12 on both sides of the climbing plate 6 to rotate. At this time, the arc-shaped protrusions 13 on the outer periphery of the rotating turntable 12 will squeeze the roller 16 during the circumferential movement, driving the movable rod 15 to compress the No. 1 return spring inside the damper 14 to move. At the same time, when the arc-shaped protrusion 13 passes over the roller 16, the roller 16 loses the contact with the arc-shaped protrusion 13. At this time, under the rebound of the No. 1 return spring, the movable rod 15 will return to its original position. During the process of moving and returning to the interior of the damper 14, the movable rod 15 drives the No. 1 piston 21 to move in the hydraulic chamber 18 to create positive and negative pressure states in the hydraulic chamber 18. When the movable rod 15 pushes the No. 1 piston 21 to move into the hydraulic chamber 18, the hydraulic oil in the hydraulic chamber 18 is transported to the nitrogen chamber 19 through the splitter 20. At this time, since two flow channels are opened in the splitter 20, namely the large-pore flow channel 23 and the small-pore flow channel 25, and the left side of the large-pore flow channel 23 is connected to a sealing plug 24 through the No. 2 return spring, which fits on the left side of the large-pore flow channel 23 to close the flow channel, Therefore, the hydraulic oil can only be discharged into the nitrogen chamber 19 through the small-hole flow channel 25. At this time, the flow rate of the hydraulic oil is greatly limited and can only pass through slowly. When the hydraulic oil reaches the nitrogen chamber 19, it will squeeze and drive the No. 2 piston 22 to compress the nitrogen on its right side. When the roller 16 loses the abutment of the arc-surface convex block 13, the No. 1 return spring on the outer periphery of the movable rod 15 and the compressed nitrogen in the nitrogen chamber 19 will rebound, causing the hydraulic oil just discharged into the nitrogen chamber 19 to flow back through the splitter 20 and return to the hydraulic chamber 18. At this time, the sealing plug 24 on the left side of the large-hole flow channel 23 will be flushed by the reverse-flowing hydraulic oil. The hydraulic oil flowing in the reverse direction can be quickly returned to the hydraulic chamber 18 through the large-hole flow channel 23 and the small-hole flow channel 25 respectively. In summary, when the turntable 12 rotates by squeezing the roller 16 to make way through the arc-surface protrusion 13, the speed at which the roller 16 drives the movable rod 15 to move into the damper 14 to make way will be damped, so that it will limit the rotation speed of the turntable 12, thereby avoiding the high-speed rotation of the turntable 12, thereby making the gear rod 9 can only rotate slowly under the engagement of the rack 8, so that the climbing plate 6 can only rise or fall slowly on the track plate 5.

[0024] Reference Figure 1 、 2 , 3, 4, 5, sprockets 26 are rotatably installed on the top and bottom ends of the fixed rod 4, and chains 27 fixed to the two climbing plates 6 are wound around the two sprockets 26. A counterweight box 28 is fixedly installed on the outer wall of the climbing plate 6 on the left track plate 5, and an oil barrel 29 is fixedly installed inside the base plate 1. An oil pump 30 is fixedly installed on the top of the oil barrel 29, and an oil hose 31 is fixedly connected to the end of the oil pump 30. The top of the oil hose 31 is connected to the counterweight box 28, and the oil barrel 29 is filled with antifreeze synthetic oil.

[0025] Through the above design, based on the damping function that the climbing plate 6 can only rise or fall slowly on the track plate 5, when the staff needs to carry items to the top of the tower 2, they can first start the oil pump 30 to pump the antifreeze synthetic oil in the counterweight box 28 into the oil barrel 29. At this time, the weight of the lifting basket 11 is higher than the counterweight box 28. Under the circuit control of the sprocket 26 and the chain 27, the lifting basket 11 will slowly descend to the top position of the base plate 1, and the counterweight box 28 will rise to the top at this time. Then the staff will carry the items to the inside of the lifting basket 11 and start again. The dynamic oil pump 30 draws the antifreeze synthetic oil in the oil barrel 29 into the counterweight box 28. At this time, the weight of the counterweight box 28 is greater than the total weight of the lifting basket 11 and the staff and items in the lifting basket 11, so that the counterweight box 28 descends through the chain 27 and the sprocket 26 to slowly lift the lifting basket 11 to the position of the workbench 3 above the tower 2, thereby completing the function of assisting the staff and items to climb and descend on the tower 2. At the same time, since the climbing and descending speed of the lifting basket 11 is controlled, it can ensure the lifting safety of the staff in this process.

[0026] The implementation principle of the embodiment of this application is:

[0027] First, by setting the relevant structure on the climbing plate 6, when the climbing plate 6 moves on the track plate 5, the rack 8 on the track plate 5 will mesh with the gear rod 9 to drive the turntables 12 on both sides of the climbing plate 6 to rotate. At this time, the arc-surface protrusions 13 on the outer periphery of the rotating turntable 12 will squeeze the roller 16 during the circumferential movement, driving the movable rod 15 to compress the No. 1 return spring inside the damper 14 to move. At the same time, when the arc-surface protrusion 13 passes over the roller 16, the roller 16 loses the contact with the arc-surface protrusion 13. At this time, under the rebound of the No. 1 return spring, the movable rod 15 will return to its original position. During the movement and return of the rod 15 to the inside of the damper 14, the movable rod 15 will drive the No. 1 piston 21 to move in the hydraulic chamber 18 to create positive and negative pressure conditions in the hydraulic chamber 18. When the movable rod 15 pushes the No. 1 piston 21 to move into the hydraulic chamber 18, the hydraulic oil in the hydraulic chamber 18 will be transported to the nitrogen chamber 19 through the splitter 20. At this time, since two flow channels are opened in the splitter 20, namely the large-pore flow channel 23 and the small-pore flow channel 25, the left side of the large-pore flow channel 23 is connected to a sealing plug 24 through the No. 2 return spring, which fits on the left side of the large-pore flow channel 23 to close the flow channel. Therefore, the hydraulic oil can only be discharged into the nitrogen chamber 19 through the small-hole flow channel 25. At this time, the flow rate of the hydraulic oil is greatly limited and can only pass through slowly. When the hydraulic oil reaches the nitrogen chamber 19, it will squeeze and drive the No. 2 piston 22 to compress the nitrogen on its right side. When the roller 16 loses the abutment of the arc-surface convex block 13, the No. 1 return spring on the outer periphery of the movable rod 15 and the compressed nitrogen in the nitrogen chamber 19 will rebound, causing the hydraulic oil just discharged into the nitrogen chamber 19 to flow back through the splitter 20 and return to the hydraulic chamber 18. At this time, the sealing plug 24 on the left side of the large-hole flow channel 23 will be blocked by the reverse-flowing hydraulic oil. The impact is opened, so that the hydraulic oil flowing in the reverse direction can quickly return to the hydraulic chamber 18 through the large-hole flow channel 23 and the small-hole flow channel 25 respectively. Based on the above principle, when the turntable 12 rotates by squeezing the roller 16 to make way through the arc-surface protrusion 13, the speed at which the roller 16 drives the movable rod 15 to move into the damper 14 to make way will be damped, so that it will limit the rotation speed of the turntable 12, thereby avoiding the high-speed rotation of the turntable 12, thereby making the gear rod 9 can only rotate slowly under the engagement of the rack 8, so that the climbing plate 6 can only rise or fall slowly on the track plate 5.

[0028] Based on the damping function that the climbing plate 6 can only rise or fall slowly on the track plate 5, when the staff needs to carry items to the top of the tower 2, they can first start the oil pump 30 to pump the antifreeze synthetic oil in the counterweight box 28 into the oil barrel 29. At this time, the weight of the lifting basket 11 is higher than the counterweight box 28. Under the circuit control of the sprocket 26 and the chain 27, the lifting basket 11 will slowly descend to the top position of the base plate 1, and the counterweight box 28 will rise to the top at this time. Then the staff will carry the items to the inside of the lifting basket 11 and start the oil pump 3 again. 0 The antifreeze synthetic oil in the oil barrel 29 is pumped into the counterweight box 28. At this time, the weight of the counterweight box 28 is greater than the total weight of the lifting basket 11 and the workers and objects in the lifting basket 11. The counterweight box 28 descends and slowly lifts the lifting basket 11 to the position of the workbench 3 above the tower 2 through the chain 27 and sprocket 26. In this way, the function of assisting workers and objects to climb and descend on the tower 2 is completed. At the same time, since the climbing and descending speed of the lifting basket 11 is controlled, it can ensure the safety of the workers in this process.

[0029] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
