Description

TECHNICAL FIELD

[0001] The present invention relates to a power system, and in particular, to a pneumatic power system. BACKGROUND

[0002] The basic principle of many power systems is to convert potential energy into kinetic energy. The kinetic energy converted by the conversion system can be used to drive the load. If the conversion system can be driven by the most easily obtained pneumatic force in the environment, it can further implement the sustainable business philosophy of increasing the proportion of renewable energy in the future. In addition, eccentric motion energy operation is a mode of using gravity distribution to coordinate the operation of the overall mechanism.

Therefore, if the pneumatic driving mechanism and the eccentric operation mechanism are combined, the units can be coordinated with each other, and the power system for converting potential energy and kinetic energy can further optimize the performance of the power system.

[0027] The present application will be described in detail below in conjunction with the drawings and embodiments.

[0028] Reference is made to Figures 1 to 3 ​, the embodiment of the pneumatic operation power system comprises an axle base unit 1, a rotating unit 2 pivotally arranged on the axle base unit 1, nine actuating displacement units 3 mounted on the rotating unit 2, a driving unit 4 connected to the actuating displacement units 3, a plurality of circulating units 5 respectively arranged on the actuating displacement units 3, and an auxiliary unit 6 arranged around the rotating unit 2 and connected to the circulating units 5. The axle base unit 1 is preferably arranged at a stable location, thereby stably supporting the rotating unit 2 and the actuating displacement units 3 of the embodiment, avoiding the influence of overall operation due to shaking. In response to different scales of construction, a foundation can also be arranged to further ensure stability.

[0029] The rotating unit 2 comprises a rotating wheel 21 capable of rotating relative to the axle base unit 1 along a transversely extending rotating shaft, nine shaft rods 22 extending outward from the rotating wheel 21 in an eccentric direction (a direction deviating from the rotating shaft), and nine box shells 23 arranged around the rotating wheel 21 and defining a plurality of inner spaces 230 respectively for containing the shaft rods 22. Among them, the nine shaft rods 22 are arranged at an interval of 40 degrees with reference to 360 degrees of rotation of the rotating wheel 21, and the number of the box shells 23 corresponds to the shaft rods 22, so as to be arranged in odd number to more easily form the overall eccentric characteristic, thereby optimizing the performance of the rotating unit 2 operating due to eccentric displacement energy. As shown in Figure 2 Each box shell 23 has an openable maintenance door 231 and a window 232 made of transparent material and located away from the rotating wheel 21.

[0030] The actuating displacement units 3 are respectively mounted on the shaft rods 22, each of which comprises a mass body 31 sleeved on the corresponding shaft rod 22 and capable of moving back and forth on the corresponding shaft rod 22, two oil seal pistons 32 arranged on opposite ends of the mass body 31 along the axial direction of the corresponding shaft rod 22, and a plurality of counterweights 33 detachably attached to the mass body 31. The positions of the counterweights 33 correspond to the maintenance doors 231, so that the maintenance doors 231 can be directly opened to adjust the counterweights 33. Each mass body 31 and the oil seal pistons 32 jointly define an oil storage and lubrication area 310 surrounding the shaft rod 22 and suitable for storing lubricating oil, and a part of the corresponding shaft rod 22 is located in the oil storage and lubrication area 310, so that the stored lubricating oil can be directly applied to the shaft rod 22. In addition, each mass body 31 has a refueling hole 311 radially penetrating and communicating with the corresponding oil storage and lubrication area 310, and a cover 312 openably closing the refueling hole 311. When the lubricating oil in the oil storage and lubrication area 310 needs to be supplemented or replaced due to reduction or deterioration, the cover 312 can be directly opened to supplement or replace the lubricating oil from the refueling hole 311.

[0031] Referring to Figure 4 with Figure 5 and in cooperation with Figure 1 The driving unit 4 includes a plurality of pneumatic cylinders 41 connected to the mass 31, a gas source 42 connected to the pneumatic cylinders 41, and a controller 43 connected to the pneumatic cylinders 41 and used to control the pneumatic cylinders 41 to drive the mass 31 to move on the shaft 22 respectively to form a whole eccentricity to rotate the rotating unit 2. In this embodiment, the gas and lubricating oil are introduced into circulation simultaneously, the gas source 42 stores enough air to operate the pneumatic cylinders 41, and an air compressor 81 is used to supply the air stored in the gas source 42 to the pneumatic cylinders 41 when the pneumatic cylinders 41 need to be replenished with air, and an air conditioning assembly 94 is used to form a proper ratio of the gas and lubricating oil to be introduced into circulation properly. In addition, solenoid valves 82 are used to control the opening and closing of the pneumatic cylinders 41, and DC power supply is used to shorten the reaction time of the control and improve the reaction speed, which is beneficial to accurately drive the mass 31 at the right time to ensure the smooth operation of the whole.

[0032] It is worth mentioning that since the pneumatic cylinders 41 must rotate with the runner 21, in order to avoid the pipelines for guiding the gas from entangling with each other during rotation, the driving unit 4 is configured with a rotary joint 83 for the gas flow path of the pneumatic cylinders 41. The rotary joint 83 includes a stator 831 connected to the gas source 42, and a rotor 832 installed on the runner 21 and capable of rotating relative to the stator 831, and having a plurality of gas holes 830 for outputting gas. The rotary joint 83 is installed on the rotating shaft of the runner 21 by a rotor fixing seat 84, the rotor fixing seat 84 is generally annular and has a plurality of radial through wiring holes 840 for the wires 91 connected to the solenoid valves 82. In addition, the controller 43 is connected to the rotary joint 83 by a power line 92 to control the gas flow between the stator 831 and the gas source 42, and a pneumatic line 93 connected to the stator 831 is used to transmit the gas output from the gas source 42 through the air conditioning assembly 94. As long as the pipelines for guiding the gas to the pneumatic cylinders 41 are installed on the gas holes 830 of the rotor 832, the pipelines can rotate with the rotor 832 and the pneumatic cylinders 41 during rotation of the runner 21, and the required gas can be supplied to the pneumatic cylinders 41 stably without the pipelines entangling with each other.

[0033] Referring to Figure 2 with Figure 3 and in cooperation withFigure 1 Each cycle unit 5 has two gas compressors 51 arranged at one end of the corresponding shaft 22 and in communication with the gas source 42 of the driving unit 4. Each gas compressor 51 has a body 511, a push rod 512 extending from the body 511 toward the corresponding mass 31, a contact piece 513 arranged at the end of the push rod 512, and a spring 514 arranged on the push rod 512 and abutting against the contact piece 513 and the body 511 at both ends, and used to accumulate elastic restoring force when the push rod 512 is pushed. The arrangement position of the gas compressor 51 at the same end corresponds to the mass 31, and when the mass 31 moves on the corresponding shaft 22, the contact piece 513 is pushed by the mass 31, thereby pushing the piston in the body 511 by the push rod 512 to output gas. At this time, the spring 514 accumulates the elastic restoring force to provide power for the reverse movement of the contact piece 513 and the push rod 512 to suck gas. In addition, in order to balance the operation of the mass 31 on the shaft 22, a rubber shock absorbing block 52 is arranged on the side opposite to the gas compressor 51 to provide a buffering effect for the reverse displacement of the mass 31.

[0034] The auxiliary unit 6 includes a plurality of gas storage pipes 61 in communication with the gas compressors 51 and the gas source 42, and a plurality of discharge pipes 62 respectively connected between adjacent gas storage pipes 61 and in communication with the gas compressors 51. The gas storage pipes 61 mainly receive the gas output by the gas compressors 51, and the discharge pipes 62 are required for the gas suction of the gas compressors 51, so that the one-way transmission requirement needs to be considered in the cycle arrangement, and a gas induction check valve 63 can be arranged to properly control the flow direction of the gas. Specifically, the gas storage pipes 61 and the discharge pipes 62 can be arranged around the outside of the box shell 23 in the shape of a ring to form a complete ring, which can directly use the box shell 23 to form support and balance the outward extension type of the box shell 23 to stabilize the overall structure.

[0035] Referring to Figure 6 and Figure 7 and cooperating Figure 5Because each mass 31 can produce position displacement in the direction perpendicular to the rotation axis of the corresponding shaft 22, when any mass 31 is subjected to external force, the actuating displacement unit 3 will be eccentric due to the loss of original balance. In terms of one operation cycle of a single actuating displacement unit 3, 0 to 360 degrees is defined as one cycle, and 0 degree is the highest and 180 degree is the lowest, which is beneficial to present the position of the actuating displacement unit 3 and the actuating cycle. In order to accurately identify the position of the actuating displacement unit 3, the infrared principle detector can be used, and the corresponding control can be performed by the control program written in advance by the controller 43 (see Figure 4 ) in cooperation with the position of the actuating displacement unit 3.

[0036] When any actuating displacement unit 3 is located at 340 degrees due to the rotation of the runner 21, the electromagnetic valve 82 of the corresponding pneumatic cylinder 41 will be opened to control the operation of the pneumatic cylinder 41, so that the mass 31 produces position displacement on the shaft 22 when the actuating displacement unit 3 is located at 30 degrees. With the continuous rotation of the runner 21, the mass 31 will continuously produce position displacement during the process of gradually rotating from 30 degrees to 160 degrees, which is the same as the operation of the pneumatic cylinder 41. Until the actuating displacement unit 3 is located at 210 degrees due to the rotation of the runner 21, the mass 31 will complete the expected position displacement due to the position displacement, the driving force provided by the pneumatic cylinder 41, and the gravity applied to the mass 31 due to the inclination of the shaft 22 from top to bottom towards the runner 21. Then, with the continuous rotation of the runner 21 due to the eccentricity caused by the mass 31, the mass 31 will gradually complete the position displacement towards the runner 21 during the process of returning from 210 degrees to 30 degrees, which is also a continuous stroke to complete a complete cycle.

[0037] Please refer to Figure 7 and Figure 8 and cooperate with Figure 2When each mass body 31 moves on the corresponding shaft 22, the gas compressor 51 located at the end of the shaft 22 away from the wheel 21 is compressed during one rotation of the wheel 21. When the gas compressor 51 is squeezed by the movement of the corresponding mass body 31, gas is discharged and directed back to the gas storage pipe 61, and then returned to the gas source 42 through the rotor 832 and the stator 831. In this way, the gas from the gas source 42 can pass through the air conditioning assembly 94, then through the stator 831 and the rotor 832, and in conjunction with the opening and closing of the solenoid valve 82, it can be resupplied to the pneumatic cylinder 41 to meet subsequent driving needs. At the same time, because the exhaust pipe 62 is also connected to the gas compressor 51, the gas discharged from the exhaust pipe 62 due to the operation of the pneumatic cylinder 41 can be used to meet the gas required by the gas compressor 51 during the operation, thereby ensuring the continuous normal operation of this embodiment. It should be noted that the gas source 42 can also be connected to multiple gas cylinders 420 ( Figure 8 Only one is shown as a representative) to meet the needs of storing or taking gas.
