Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude wind energy, in particular to a lifting universal wheel friction device. Background Art

[0002] By 2060, the proportion of clean energy in my country's primary energy consumption will increase from the current 15.9% to 83%. Wind power and photovoltaics are developing rapidly and will become the primary clean energy sources after 2030. By 2050, wind power will account for 26% of total primary energy demand, rising further to 31% by 2060. The world currently needs an energy source that is environmentally friendly, renewable, and economical. Currently available power generation technologies cannot simultaneously meet these three requirements: resource availability, reliability, and environmental protection. Research has shown that high-altitude wind energy has the potential to meet all three. High-altitude wind energy has been developed for over 20 years. The new parachute-ladder high-altitude wind power generation technology consists of three parts: aerial equipment, ground equipment, and a control system. By controlling the opening and closing of the parachute assembly, the parachute assembly moves up and down in a circular motion, which in turn drives a ground-based generator to generate electricity, thereby converting wind energy into mechanical energy, which then drives the generator assembly to generate electrical energy. The wind speed at high altitude is high and its density is generally tens to hundreds of times that of ground wind energy. By placing a balloon in the air and using a power parachute to drive the ground friction reel, the tension drives the mechanical equipment, converting wind energy into mechanical energy, and then converting mechanical energy into electrical energy.

[0003] Using two auxiliary lifting winches, start the 10T winch, press the rope release button to loosen the 10T winch cable, the balloon will rise and drift above the 20T winch, start the 20T winch, press the rope retraction button to pull the helium balloon to the 20T winch universal wheel, and then hang the main cable to lift it into the air. During the lift-off process, the wind speed was too high and the main cable swung too much, causing the main cable to rub against the iron plate at the upper end of the universal wheel guide rail. Over time, the main cable will wear and break, causing the helium balloon to escape. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a lifting universal wheel friction device, which solves the problem that the wind speed is too high during the lifting process, the main cable shakes too much, causing the main cable to rub against the iron plate at the upper end of the universal wheel guide rail. Over time, the main cable will wear and break, causing the helium balloon to escape.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a lifting universal wheel friction device. It includes a main frame, one end of which is downwardly extended with a roller connecting plate, the other end of which is movably connected to a fixed plate, the interior of which is movably connected to vertical rollers, both ends of which are fixedly connected to connecting members, the interior of which is movably connected to newly added horizontal rollers, the bottom of which is movably connected to a horizontal roller, the inner side of which is movably connected to a connecting shaft, one end of which is fixedly connected to a buffer plate, and the outer side of which is sleeved with a buffer pressing sheet.

[0006] Preferably, a reinforcement plate extends upward from the middle portion of the main frame.

[0007] Preferably, a fixing screw is provided through the side of the fixing plate, one end of the main frame and the reinforcement plate extends to both ends and is connected to the side of the fixing plate through the fixing screw, and one end of the fixing screw is rotatably connected to a fixing nut.

[0008] Preferably, the main frame and the fixed plate are installed at the universal wheel, and the main cable passes through the middle of the vertical roller and between the newly added horizontal roller and the horizontal roller and enters the universal wheel.

[0009] Preferably, a buffer cavity is protruded outward from the middle of the buffer pressing plate, and the buffer pressing plate is symmetrically arranged about the connecting axis.

[0010] Preferably, the side of the buffer plate where the main cable is provided is arranged in an arc shape.

[0011] The utility model provides a lifting universal wheel friction device. Compared with the prior art, it has the following beneficial effects:

[0012] 1. The lifting universal wheel friction device is installed by installing the main frame and the fixed plate on the universal wheel. The main cable passes through the middle of the vertical roller and between the newly added horizontal roller and the horizontal roller and then enters the universal wheel. When the helium balloon is launched and the wind direction changes, the main cable moves upward. Under the clamping action of the vertical roller, it will not deviate significantly at one end of the main frame. The rotation of the newly added horizontal roller will reduce the friction between the cable and the newly added horizontal roller, and will not rub against the iron plate at the upper end of the guide rail, causing wear of the main cable.

[0013] 2. The lifting universal wheel friction device is equipped with a buffer pressure plate at one end of the buffer plate. Since the buffer pressure plate is symmetrically arranged about the connecting axis, there is a gap between the buffer cavities. When the main cable moves upward, the working parachute moves up and down, which will generate pressure on the inner side of the roller connecting plate. The space between the buffer pressure plates due to the buffer cavity can buffer the pressure generated by the main cable on the side of the buffer plate, thereby preventing the main cable from contacting the roller connecting plate during movement and causing friction between the main cable and the roller connecting plate, which will cause wear of the main cable.

The main frame 1 is internally movably connected with a vertical roller 3, and the vertical roller 3 is used to limit the movement space of the main cable in the vertical direction. The two ends of the roller connecting plate 100 are fixedly connected with a connector 5, and the interior of the connector 5 is movably connected with a newly added horizontal roller 4. The roller connecting plate 100 The bottom is movably connected to a horizontal roller 6, and the main cable is connected to the working parachute by passing through the gap between the newly added horizontal roller 4 and the horizontal roller 6. The inner side of the roller connecting plate 100 is movably connected to a connecting shaft 8, and one end of the connecting shaft 8 is fixedly connected to a buffer plate 7. The outside of the connecting shaft 8 is sleeved with a buffer pressure plate 9, and the connecting shaft 8 is used to fix the buffer plate 7 to the inner side of the roller connecting plate 100. The buffer pressure plate 9 has a cavity formed by a raised buffer cavity 900 in the middle, which can buffer the friction generated between the column cable and the roller connecting plate 100 during movement, causing wear.

[0021] See also Figure 1-4 , a reinforcing plate 102 extends upward from the middle of the main frame 1, and the reinforcing plate 102 is used to reinforce the device so that the device can still be fixed under the pull of the main cable. A fixing screw 11 is provided on the side of the fixing plate 2. The main frame 1 and one end of the reinforcing plate 102 extend to both ends and are connected to the side of the fixing plate 2 by the fixing screw 11. One end of the fixing screw 11 is rotatably connected to the fixing nut 12. The main frame 1, the reinforcing plate 102 and the fixing plate 2 are fixedly connected by the fixing screw 11 and the fixing nut 12. The main frame 1 and the fixing plate 2 are installed At the universal wheel, the main cable passes through the middle of the vertical roller 3 and between the newly added horizontal roller 4 and the horizontal roller 6 to enter the universal wheel. The middle part of the buffer pressure plate 9 protrudes outward with a buffer cavity 900. The buffer pressure plate 9 is symmetrically arranged about the connecting shaft 8. The side of the buffer plate 7 where the main cable is arranged is arranged in an arc shape. The space formed between the buffer cavities 900 is deformed when the main cable squeezes the surface of the buffer plate 7, thereby buffering the received pressure.

Since the buffer pressure plate 9 is symmetrically arranged about the connecting axis 8, there is a gap between the buffer cavities 900. When the main cable moves upward, the working parachute moves up and down and generates pressure on the inner side of the roller connecting plate 100. The space between the buffer pressure plates 9 due to the buffer cavity 900 can buffer when the main cable generates pressure on the side of the buffer plate 7, thereby preventing the main cable from contacting the roller connecting plate 100 during movement and causing friction between the main cable and the roller connecting plate 100.
