Description

[0001] 1. Technical field: The product of the present invention belongs to the field of hydraulic machinery and electric machinery manufacturing.

[0002] 2. Background technology: The hydraulic rotary jack circulating power generation technology device uses the hydraulic rotary jack invented by myself. The invention patent number is: ZL201710659388.X. The hydraulic rotary jack has the unique characteristics and features of fast speed and large torque. Through the innovative body device structure, the mechanical energy is converted into electrical energy, further expanding the new technical field and extending the novelty, creativity, and practicality of the invention patent. 3. Summary of the invention:

[0003] According to Pascal's law and principle that the pressure change of a part of the static fluid in a closed container due to the fluidity of the liquid will be transmitted to all directions without changing its size, and according to the unique characteristics and features of the hydraulic rotary jack with fast speed and large torque, the body device architecture is innovative, two or more oil inlets are opened at the bottom of the hydraulic rotary jack cylinder, each oil inlet is connected to the oil outlet of a hydraulic oil pump with the same performance parameters of motor power, speed, flow and pressure, so that two or more hydraulic oil pumps are assembled into one with a closed hydraulic rotary jack cylinder with fixed volume to form a hydraulic rotary jack original power device, and then the technology of synchronously injecting oil into the same closed hydraulic rotary jack cylinder with fixed volume by two or more hydraulic oil pumps with the same performance parameters is adopted. Two important concepts in physics: when multiple forces act on an object at the same time, the effects of these forces can be superimposed, and the final result is equal to the vector sum of these forces; when multiple forces are pushing the object, the acceleration of the object is equal to the vector sum of multiple thrusts. The hydraulic rotary jack circulating power generation technology device utilizes this principle to innovate the body structure. When two or more hydraulic oil pumps synchronously pressurize oil into the same closed hydraulic rotary jack cylinder with a fixed volume, the synchronous outlet pressure, flow rate, and displacement of multiple hydraulic oil pumps act on the same closed hydraulic rotary jack cylinder with a fixed volume, which will increase the volume, flow rate, pressure, and pressure of the oil in the hydraulic rotary jack cylinder, and double the force. At the same time, the synchronous outlet pressure, flow rate, and displacement of multiple hydraulic oil pumps act on the upper side force surface of the pin piston of the same closed hydraulic rotary jack with a fixed volume, which will cause the output initial speed, output initial torque, and output power of the hydraulic rotary jack pin piston rotor to be synchronously doubled. This is the principle and effect of force superposition in a closed container. In this way, we can make full use of the doubled output initial speed and output initial torque to realize the hydraulic rotary jack circulating power generation technology.

[0004] Why does the hydraulic rotary jack circulating power generation technology device have such application scenarios and efficiency? This mainly depends on: 1. Changing the normal technical mode of a single hydraulic oil pump to pressurize the oil into the hydraulic rotary jack cylinder, and adopting a technology in which two or more hydraulic oil pumps with the same performance parameters are synchronously pressurized into the same closed volume fixed hydraulic rotary jack cylinder. In the closed volume fixed cylinder, the force superposition principle and effect make the hydraulic rotary jack pin piston rotor output the initial speed, output the initial torque, and double the output power. As long as the hydraulic rotary jack shell design can withstand a sufficiently large hydraulic oil pressure and does not leak oil, the technical purpose of the hydraulic rotary jack circulating power generation can be achieved; 2. Hydraulic rotary jack machine The mechanical structure is basically the same as that of the hydraulic jack, which is nothing more than a push-pull force and moment structure, and a rotational torque structure. In hydraulic equipment, their force, moment, torque, and power are the largest and the same; 3. The hydraulic rotary jack is small in size, and outputs rotational motion at a fast speed, and directly outputs torque. The hydraulic jack is large in size, and outputs linear push-pull motion at a slow speed, and outputs torque. For example, the conversion of torque into torque requires a crankshaft structure or other structure conversion with a slow speed, and there is a force difference in the push-pull force, which has a certain impact on the torque. The hydraulic rotary jack does not have such a problem. This is the significant feature and advantage of the hydraulic rotary jack in the application of circulating power generation technology.

[0005] The hydraulic rotary jack circulating power generation technology device can carry out single-unit capacity circulating power generation and cluster-unit capacity circulating power generation, which is equivalent to a power plant or a power station; it can carry electric vehicles, electric vehicles, and electric motorcycles for circulating power generation, which is equivalent to the vehicle engine, realizing the vehicle's self-generation, self-power supply, and self-charging cycle for continuous power generation and continuous endurance leading technology. 4. Description of the drawings:

[0006] Attached Figure 1 This is a schematic diagram of a hydraulic rotary jack cycle power generation technology device.

[0007] Attached Figure 2 It is the structural view of hydraulic bidirectional rotating jack

[0008] Attached Figure 3 It is the structural view of hydraulic one-way rotating jack V. Specific implementation methods:

[0009] The application of the hydraulic rotary jack circulating power generation technology device is to convert the torque mechanical energy of the hydraulic rotary jack into electrical energy. Specifically, the hydraulic oil pump injects hydraulic oil into the hydraulic rotary jack cylinder to drive the hydraulic rotary jack pin piston rotor to rotate, and the hydraulic rotary jack rotor shaft fly gear engages the generator rotor shaft gear to rotate the generator rotor to generate electricity and amplify the power, that is, small motor power input and large generator power output, and the output power is divided into two paths. One path of power output is for load power, including power, auxiliary equipment power and other power, and the other path of power is for circulating power supply, including charging batteries, starting vehicles, and maintaining effective endurance when vehicles encounter failures. The hydraulic rotary jack circulating power generation technology device is highly safe, low cost, zero emission, and pollution-free.

[0010] Specific implementation 1: Assume that the hydraulic rotary jack has a circular cylinder centerline radius of 0.1M, the force area of ​​the upper side of the latch piston is 0.05*0.03=0.0015 square meters, the volume of the circular cylinder is 3.14*2*0.1*0.0015=0.000942 cubic meters, which is equal to 0.942 liters, and the flow rate is 30L / min oil pump (it is best to configure a plunger pump because the plunger pump has a strong pressure), the oil pump outlet working pressure is 16MPa, the motor power is 9.8KW (it is best to configure a variable frequency motor, which is more stable), and the motor speed 1440n / min, oil pump displacement = flow / motor speed, that is, 30 / 1440 = 0.02083L / n, the speed of the hydraulic rotary jack is 0.942 / 0.02083 = 45, that is, the motor needs to rotate 45 times to make the hydraulic rotary jack rotate one circle, then the hydraulic rotary jack rotates 1440 / 45 = 32 times per minute (initial speed), and the thrust of the hydraulic rotary jack is equal to the force area of ​​the upper side of the pin piston * the working pressure of the oil pump outlet * pa, that is, 0.0015*16*1000000 =24000pa, which is equal to 24000N, then the center radius of the hydraulic rotary jack cylinder is 0.1M, so the torque of the hydraulic rotary jack is 24000*0.1=2400NM (initial torque), and the output torque of the hydraulic rotary jack drives the generator to generate electricity. The generator power P=torque T*speed n / 9550, that is, P=2400*32 / 9550=8.04KW, and the output power is 82% of the input motor power. The output power is less than the input power. In this sense, the output speed of the hydraulic rotary jack is 2400*0.1=2400NM (initial torque). The torque is smaller than the torque required by the generator according to the technical requirements. The torque required by a 9.8KW generator is T=9550*9.8 / 32, that is, T=2924.7NM, while the output torque of the hydraulic rotary jack is 2400NM, which is only 82% of the torque required by the generator, that is, the effective torque of the hydraulic rotary jack is 82%. Therefore, the torque of a single hydraulic rotary jack is smaller than the input torque of the generator, and the converted energy is insufficient. Then how can the torque of the hydraulic rotary jack be converted into large energy, with the output power being greater than the input power, and applied to large-energy power generation technology?

[0011] Specific implementation 2: Innovative machine body device architecture, using two hydraulic oil pumps with the same performance parameters to simultaneously pressurize the same closed volume fixed hydraulic rotary jack cylinder.

[0012] The relevant technical parameters take the specific implementation data as an example: the radius of the center line of the round cylinder of the hydraulic rotary jack is 0.1M, the force area of ​​the upper side of the latch piston is 0.05*0.03=0.0015 square meters, and the volume of the round cylinder is 3.14*2*0.1*0.0015=0.000942 cubic meters, which is equal to 0.942 liters.

[0013] The flow rate of a single oil pump is 30L / min (it is best to configure a plunger pump because the plunger pump has a strong pressure), the sum of the flow rates of the two oil pumps is 60L / min, the outlet working pressure of a single oil pump is 16MPa, the sum of the outlet working pressures of the two oil pumps is 32MPa, the power of a single motor is 9.8KW (it is best to configure a variable frequency motor, which is more stable), the sum of the power of the two motors is 19.6KW, the speed of a single motor is 1440n / min, the sum of the speed of the two motors is 2880n / min, the displacement of the oil pump = flow rate / motor speed, that is, 60 / 2880 = 0.02083L / n, and the speed of the hydraulic rotary jack is 0.942 / 0.02083 = 45, that is, the motor needs to rotate 45 times to make the hydraulic rotary jack rotate one circle, then the hydraulic rotary jack rotates 2880 / 45 = 64 times per minute ( Initial speed), the thrust of the hydraulic rotary jack is equal to the force area of ​​the upper side of the pin piston * the working pressure of the oil pump outlet * Pa, that is, 0.0015*32*1000000=48000 Pa, which is equal to 48000N. Then the center radius of the hydraulic rotary jack cylinder is 0.1M, so the torque of the hydraulic rotary jack is 48000*0.1=4800NM (initial torque). The output torque of the hydraulic rotary jack drives the generator to generate electricity. The generator power P=torque T*speed n / 9550, that is, P=4800*64 / 9550=32.17KW. The output power is 1.64 times the input motor power, and the output power is greater than the input power. In this sense, it is feasible to change the structure of the hydraulic rotary jack device and realize the power generation technology of the hydraulic rotary jack output power greater than the input power.

[0014] Specific implementation three: Innovative machine body device architecture, using four hydraulic oil pumps with the same performance parameters to simultaneously pressurize the same closed volume fixed hydraulic rotary jack cylinder.

[0015] The relevant technical parameters are still taken as an example of a specific implementation data: the radius of the center line of the hydraulic rotary jack is 0.1M, the force area of ​​the upper side of the latch piston is 0.05*0.03=0.0015 square meters, and the volume of the round cylinder is 3.14*2*0.1*0.0015=0.000942 cubic meters, which is equal to 0.942 liters.

[0016] The flow rate of a single oil pump is 30L / min (it is best to configure a plunger pump because the plunger pump has a strong pressure), the sum of the flow rates of the four oil pumps is 120L / min, the outlet working pressure of a single oil pump is 16MPa, the sum of the outlet working pressures of the four oil pumps is 64MPa, the power of a single motor is 9.8KW (it is best to configure a variable frequency motor, which is more stable), the sum of the power of the four motors is 39.2KW, the speed of a single motor is 1440n / min, the sum of the speed of the four motors is 5760n / min, the oil pump displacement = flow rate / motor speed, that is, 120 / 5760=0.02083L / n, and the speed of the hydraulic rotary jack is 0.942 / 0.02083=45, that is, the motor needs to rotate 45 times to make the hydraulic rotary jack rotate one circle, then The hydraulic rotary jack rotates 5760 / 45=128 times per minute (initial speed). The thrust of the hydraulic rotary jack is equal to the force area of ​​the upper side of the latch piston * the working pressure of the oil pump outlet * pa, that is, 0.0015*64*1000000=96000 pa, which is equal to 96000 N. Then the center radius of the hydraulic rotary jack cylinder is 0.1 M, so the torque of the hydraulic rotary jack is 96000*0.1=9600 NM (initial torque). The output torque of the hydraulic rotary jack drives the generator to generate electricity. The generator power P=torque T*speed n / 9550, that is, P=9600*128 / 9550=128.67 KW. The output power is 3.28 times the input motor power, and the output power is greater than the input power.

[0017] That is, the total transmission efficiency of the hydraulic system and mechanical system of the hydraulic rotary jack power generation technology device is 70%. This total efficiency is the minimum parameter standard (theoretically, the total transmission efficiency of the hydraulic system and mechanical system is generally 83%), 128.67KW*70%=90KW, the output power is 2.23 times greater than the input power. If calculated based on the total efficiency of 83%, 128.67KW*83%=106.8KW, the output power is 2.72 times greater than the input power.

[0018] The three specific implementation cases of the hydraulic rotary jack circulating power generation technology device mentioned above can prove that as long as the combined assembly structure of the hydraulic rotary jack and the hydraulic oil pump is changed, the output power of the hydraulic rotary jack circulating power generation technology device can be greater than the input power power generation technology requirement, and the power generation power is doubled or doubled as the oil pump with the same performance parameters presses more or less oil into the same closed volume fixed hydraulic rotary jack cylinder. The hydraulic rotary jack circulating power generation technology device is completely feasible and has practical significance.

[0019] At the same time, the three specific implementation cases of the hydraulic rotary jack circulating power generation technology device mentioned above also prove that when the output initial speed and output initial torque generated by the hydraulic rotary jack circulating power generation technology device are large enough, we can increase the output initial speed of the hydraulic rotary jack circulating power generation technology device. The output initial speed can generally be maintained at more than 20 revolutions per minute, and the input increase rate can reach more than 1000 revolutions per minute. For example, in wind power generation technology, although the wind impeller speed is between 19-30 revolutions per minute, the huge wind impeller torque is very large, so it can increase the input generator speed to 1500 revolutions per minute, which can also provide convenient conditions for configuring high-speed generators with very few magnetic poles.

[0020] The hydraulic rotary jack circulating power generation technology device can be applied to various specifications and models, with single-unit capacity and cluster unit capacity installation design, and the scale can be a power plant and a power station.

[0021] The hydraulic rotary jack circulating power generation technology device can be applied to the design of electric vehicles, electric vehicles, and electric motorcycles of various specifications and models, and realize the integrated continuous endurance technology of self-generation, self-power supply, and self-charging of electric vehicles, electric vehicles, and electric motorcycles.

[0022] According to relevant literature, small cars consume about 10-15 degrees of electricity per 100 kilometers, buses consume about 80 degrees of electricity per 100 kilometers, and electric motorcycles and electric vehicles consume even less electricity per 100 kilometers.

[0023] For example, if a small car uses the hydraulic rotary jack of the above-mentioned specific specifications and models and is equipped with four 2.14KW motor hydraulic pumps (oil pump flow rate 15L / min, oil pump outlet working pressure 7MPa), it can generate 28KW of electricity per hour. If the total efficiency is 70%, it can generate 19.7KW of electricity per hour. If the total efficiency is 83%, 28KW*83%=23.24KW.

[0024] The hydraulic rotary jack circulating power generation technology device is small in size, light in weight and high in power. It can be designed according to the technical parameters of different specifications and models of vehicles. The entire device can be placed under the hood or in the trunk without changing the body shape structure and fluid mechanics structure.
