Description

Technical Field

[0002] Vibration energy recovery technology stems from the global demand for energy conservation and environmental protection. Traditional energy consumption methods have placed a huge burden on the environment, while vibration energy recovery technology can use the energy generated by mechanical vibration for recycling and reuse, thereby reducing the consumption of natural resources and environmental pollution. In addition, vibration is also ubiquitous in modern society, such as transportation vehicles and mechanical equipment. The mechanical energy generated by them during operation can be recycled and reused, which can provide energy for other low-power devices, and can extend the service life of equipment, reduce energy consumption and improve energy utilization efficiency.

[0003] At present, when mechanical equipment vibrates, although the energy recovery device can recover kinetic energy, it is inconvenient to use kinetic energy conversion to maintain the energy recovery device.

[0034] The recovery conversion mechanism 2 includes a recovery unit 21, which is arranged on the top of the housing 1. The recovery unit 21 is used to limit the piston rod 12 to reduce the vibration generated by the piston rod 12.

[0035] As a further limitation of the recycling conversion mechanism 2 of the present invention, the recycling unit 21 includes an air pipe 2101, the number of the air pipes 2101 is two, the two air pipes 2101 are fixedly installed on the surface of the shell 1, the inner cavity of the air pipe 2101 is connected to the inner cavity of the shell 1, one end of the two air pipes 2101 is fixedly connected to a positioning shell 2102, the positioning shell 2102 is fixedly installed on the top of the shell 1, the inner cavity of the positioning shell 2102 is slidably connected to a sealing plate 2103, and two springs 2104 are provided on one side of the sealing plate 2103, one end of the spring 2104 is fixedly connected to the sealing plate 2103, and the spring 2104 The other end is fixedly connected to the inner wall of the positioning shell 2102, and one side of the sealing plate 2103 is fixedly connected with a block 2105, and one side of the block 2105 penetrates to the outside of the positioning shell 2102; by setting the recovery unit 21, during the vibration of the mechanical equipment, the piston rod 12 is used to apply pressure to the square piston plate 13, so that the kinetic energy of the vibration of the mechanical equipment can be converted into pneumatic pressure, and the pneumatic pressure is used to provide power for the recovery unit 21, so that the recovery unit 21 can clamp and position the piston rod 12, reduce the vibration of the piston rod 12 and the mechanical equipment, avoid wear and tear caused by long-term vibration of the mechanical equipment, and thus protect the mechanical equipment.

[0036] Limiting frames 2106 are provided on both sides of the positioning shell 2102, the bottom of the limiting frame 2106 is fixedly connected to the top of the shell 1, and the side of the limiting frame 2106 close to the positioning shell 2102 is in contact with the surface of the positioning shell 2102; by providing the limiting frame 2106, the positioning shell 2102 can be limited to avoid the position of the positioning shell 2102 being offset when in use.

[0038] There are two clamping blocks 2105, both of which are arranged on the outer surface of the piston rod 12, and the inner cavity of the clamping block 2105 is fixedly connected with a rubber ring 2109; by setting the rubber ring 2109, the piston rod 12 can be protected to prevent the surface of the piston rod 12 from being damaged when the clamping block 2105 clamps the piston rod 12.

[0039] The specific implementation of this embodiment is as follows: in order to recover the kinetic energy of the mechanical equipment, the staff connects one end of the piston rod 12 to the vibrating part of the mechanical equipment. When the mechanical equipment vibrates, the piston rod 12 is driven to move. When the piston rod 12 moves, it drives the square piston plate 13 to move. When the square piston plate 13 moves, it squeezes the air in the inner cavity of the shell 1, so that the air enters the inner cavity of the positioning shell 2102 through the air delivery pipe 2101. Since the gas pressure on one side of the inner cavity of the positioning shell 2102 is relatively large, the gas on one side squeezes the sealing plate 2103 and drives the sealing plate 2103 to move. The sealing plate 210 During the movement, the spring 2104 is squeezed and the clamping block 2105 is driven to move. When the two clamping blocks 2105 move toward each other to clamp the piston rod 12, the piston rod 12 stops moving downward. After the sealing plate 2103 is not impacted by the gas pressure, the sealing plate 2103 is driven to move under the reaction force of the spring 2104, so that the gas in the inner cavity of the positioning shell 2102 flows back to the inner cavity of the shell 1. The piston rod 12 is positioned by the clamping block 2105, which can reduce the vibration frequency of the piston rod 12 and the mechanical equipment, thereby protecting the mechanical equipment and preventing the wear of internal parts caused by excessive vibration frequency of the mechanical equipment.

[0040] Example 2: Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The present invention provides a technical solution: a hybrid vibration energy recovery device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The recovery conversion mechanism 2 also includes an oil injection unit 22. The oil injection unit 22 is used in conjunction with the recovery unit 21. The oil injection unit 22 is arranged on the top of the shell 1. The oil injection unit 22 is used to add lubricating oil to the surface of the piston rod 12.

[0041] As a further limitation of the recovery conversion mechanism 2 of the present invention, the oil injection unit 22 includes a fixed shell 2201, the number of the fixed shells 2201 is two, the two fixed shells 2201 are fixedly installed on the top of the shell 1, and a micro cylinder 2202 is fixedly installed on the top of the fixed shell 2201. One side of the micro cylinder 2202 is fixedly connected with a connecting pipe 2203, and the other end of the connecting pipe 2203 is fixedly connected with the inner cavity of the positioning shell 2102. The output end of the micro cylinder 2202 passes through the inner cavity of the fixed shell 2201 and is fixedly connected with a circular piston plate 2204.

There are two nozzles 2208, and the two nozzles 2208 are both provided with the outer surface of the piston rod 12; by setting the oil injection unit 22, the kinetic energy generated by the vibration of the mechanical equipment can be converted into pneumatic pressure, thereby applying pressure to the piston in the inner cavity of the micro cylinder 2202, so that the lubricating oil is sprayed on the surface of the piston rod 12, thereby reducing the wear of the piston rod 12 during use, thereby increasing its service life.

[0042] A positioning plate 2209 is fixedly connected between the bottoms of the two nozzles 2208. The positioning plate 2209 is fixedly installed on the top of the shell 1.

By setting the positioning plate 2209, on the one hand, the nozzle 2208 can be positioned to improve the stability of the nozzle 2208 spraying lubricating oil. On the other hand, after the lubricating oil is added to the surface of the piston rod 12, it can fully contact with the piston rod 12 so that the lubricating oil is evenly applied on its surface.

[0043] The specific implementation of this embodiment is as follows: after the gas in the inner cavity of the shell 1 applies pressure to the sealing plate 2103 through the gas pipe 2101, the sealing plate 2103 drives the block 2105 to move, and the sealing plate 2103 squeezes the gas on the other side when moving, so that the gas is discharged into the inner cavity of the micro cylinder 2202 through the connecting pipe 2203, and the gas is used to apply pressure to the piston in the inner cavity of the micro cylinder 2202, so that the piston drives the circular piston plate 2204 to move downward, and the circular piston plate 2204 squeezes the lubricating oil in the inner cavity of the oil storage shell 2206 when moving downward, so that the lubricating oil flows into the nozzle 2208 through the oil pipe 2207, and then is sprayed onto the surface of the piston rod 12 by the nozzle 2208. The kinetic energy of the mechanical equipment is converted into pneumatic pressure to push the lubricating oil, which can automatically add lubricating oil to the piston rod 12, reduce the wear of the piston rod 12, and thus increase its service life.
