Description

Technical Field

[0001] The present invention relates to the technical field of power generation, and in particular to a self-powered generator module and a power generation method thereof. Background Art

[0002] In the current power generation system field, the main utilization mode is energy conversion, such as thermal power generation, hydropower generation, wind power generation, and the method of using circulating water flow to generate electricity. However, this type of energy conversion has different defects and is subject to natural factors, energy consumption and environmental pollution. Therefore, a variety of environmentally friendly and clean power supply modules have been designed on the market.

[0003] Existing self-powered generator sets generally include an electric motor, a speed increaser, a generator and a transformer. The speed increaser is driven by the electric motor to operate. When the speed increaser rotates, it increases from low speed to high speed, generating a large shaft torque, and then drives the generator to rotate and generate electricity, converting mechanical energy into electrical energy output. Part of the output electrical energy is used back to drive the motor, and the rest of the electrical energy is output to the outside, thereby realizing environmentally friendly and clean electricity supply, such as Chinese patent: 202010924479.3; however, the generator in this type of generator set will still use more electricity, which makes the cost of the generator set slightly higher and the utilization value is limited. Summary of the invention

[0004] The object of the present invention is to provide a self-powered generator module and a power generation method thereof which have low cost, good benefits and high comprehensive utilization value.

[0005] To solve the above technical problems, the present invention can be implemented by the following technical solutions: A self-powered generator module, comprising: A control assembly, including a control box and a motor, wherein the control box is connected to an external power supply; an energy increasing and decreasing unit, wherein the energy increasing and decreasing unit is connected to the motor, the motor drives the energy increasing and decreasing unit to rotate, and controls the rotation speed of the energy increasing and decreasing unit; a power amplifier, the power amplifier being connected to the energy increasing and decreasing unit and used for converting the low speed of the energy increasing and decreasing unit into a high speed and transmitting the high speed to the generator for rotation and power generation; A substation cabinet is connected to a generator. The generator converts mechanical energy into power and transmits it to the substation cabinet. The power is then transmitted from the substation cabinet to a transformer and then incorporated into the power grid. A small part of the power incorporated into the power grid can be used as an external power source.

[0006] In one embodiment, the energy increase and decrease unit includes a mounting seat and a rotating vehicle. The rotating vehicle is mounted on the mounting seat and connected to an electric motor. A plurality of force-bearing buckets are arranged on the rotating vehicle. The mounting seat can be arranged in a river, stream or ditch. The water flow pushes the force-bearing buckets to rotate the rotating vehicle.

[0007] In one embodiment, the energy increase and decrease unit also includes a water hammer pump, which introduces water from a low place to a high place. The water at the high place flows to the force-bearing bucket of the rotary vehicle through a pipeline, thereby pushing the force-bearing bucket to rotate the rotary vehicle.

[0008] In one embodiment, the motor is a three-phase AC motor, and the rated power of the motor is 5.5KW.

[0009] In one embodiment, the generator is a three-phase AC synchronous generator, or a DC generator combined with a DC-AC inverter, and the rated power of the generator is at least 300KW.

[0010] In one embodiment, the average rotation speed of the rotary vehicle is 3.2 rpm.

[0011] The present invention also provides a method for generating electricity using a self-powered generator module, comprising the following steps: S1. The mounting base in the energy increase and decrease unit is set at a river, stream or ditch, so that the rotary vehicle is in the water flow, and then the motor and the power amplifier are respectively assembled with the rotary vehicle to form a rotation connection, and the generator is also assembled with the power amplifier to form a rotation connection, and the transformer cabinet is assembled and connected with the generator; S2. Start the control box through an external power supply. The control box drives the motor to rotate. When the motor rotates, it drives the wheel vehicle to rotate, and cooperates with the water flow of rivers, streams or ditches to ensure the average speed of the wheel vehicle. The wheel vehicle transmits the speed to the power amplifier, which increases the speed to the set speed and then transmits it to the corresponding generator. The generator converts the mechanical energy into electrical energy, and transmits the electrical energy to the substation. The substation transmits the power to the transformer and then connects it to the power grid, and a small part of the electrical energy is used for external power supply.

[0012] In one of the embodiments, in step S1, the mounting seat can also be set in a circulating water pool, and the circulating water from the lower part of the circulating water pool can be introduced to a higher place by a water hammer pump, and then the force-bearing bucket of the rotary vehicle is impacted from high to low through a pipeline to make the rotary vehicle rotate. Beneficial Effects

[0013] The self-powered generator module and the power generation method thereof of the present invention start the control box through an external power supply, and then the control box drives the motor to rotate. When the motor rotates, it combines with the water flow to push the rotary vehicle, and when the rotary vehicle rotates, it drives the power amplifier, and the power amplifier amplifies the rotation speed and transmits the set rotation speed to the generator. The generator converts mechanical energy into electrical energy and transmits the electrical energy to the substation cabinet. The substation cabinet then transmits the electrical energy to the transformer and then directly connects it to the power grid, while a small part of the electrical energy is used to start the control box with an external power supply, and most of the electrical energy is output to the outside. Finally, through the combination of the motor and the energy increase and decrease unit, the power consumption of the motor can be reduced, thereby reducing costs, improving the benefits of the generator module, and making its comprehensive utilization value higher.

[0019] See also Figures 1 to 4 , a self-powered generator module, comprising: A control assembly 100 includes a control box 110 and a motor 120, wherein the control box 110 is connected to an external power source; An energy increase / decrease unit 200, wherein the energy increase / decrease unit 200 is connected to the motor 120, and the motor 120 drives the energy increase / decrease unit 200 to rotate, and controls the rotation speed of the energy increase / decrease unit 200; A power amplifier 300, which is connected to the energy increase / decrease unit 200 and is used to convert the low speed of the energy increase / decrease unit 200 into a high speed and transmit it to the generator 400 for rotation and power generation; A transformer cabinet 500 is connected to a generator 400. The generator 400 converts mechanical energy into electrical energy and transmits it to the transformer cabinet 500. The transformer cabinet 500 then transmits the electrical energy to a transformer 600 and then connects it to the power grid. A small portion of the power connected to the power grid can be used as an external power source.

[0020] Among them, the energy increase and decrease unit 200 includes a mounting seat 210 and a rotating vehicle 220. The rotating vehicle 220 is mounted on the mounting seat 210 and connected to the motor 120. A plurality of force buckets 221 are arranged on the rotating vehicle 220. The mounting seat 210 can be arranged in a river, stream or ditch. The water flow pushes the force buckets 221 to rotate the rotating vehicle 220.

[0021] Specifically, in this embodiment, the mounting base 210 of the energy increase and decrease unit 200 is set in a river, stream or ditch, and the rotary vehicle 220 of the energy increase and decrease unit 200 is placed in the water flow, the motor 120 and the power amplifier 300 are respectively connected to the rotary vehicle 220 for rotation, the generator 400 is connected to the power amplifier 300 for rotation, and the transformer cabinet 500 is respectively connected to the generator 400 and the transformer 600. When the external power supply is connected to the control box 110, the control box 110 can start the motor 120 to rotate. When the motor 120 rotates, it will drive the rotary vehicle 220 to rotate, and the rotary vehicle 220 placed in the water flow will also push the force bucket 221 to rotate with the water flow, and the two are combined to thereby The power consumption of the motor 120 can be reduced, and when the rotary vehicle 220 rotates, the power amplifier 300 is driven to work, and the power amplifier 300 increases the speed to reach the set corresponding speed, and transmits it to the generator 400. The generator 400 converts the mechanical energy into electrical energy and transmits it to the substation 500. The substation 500 then transmits the electrical energy to the transformer 600 and directly connects it to the power grid. A small part of the electrical energy is then used as an external power supply to start the control box 110, and most of the electrical energy is output to the outside to realize self-circulating power generation. Finally, through the combination of the motor 120 and the energy increase and decrease unit 200, the power consumption of the motor 120 can be effectively reduced, thereby reducing costs, improving the efficiency of the generator module, and making its comprehensive utilization value higher.

[0022] In addition, due to external factors, the flow rate of the water flow cannot be controlled. Therefore, the average speed of the rotary cart 220 in this embodiment is controlled at 3.2rpm. When this average rotation is reached, the control box 110 can stop the motor 120 from working, thereby effectively reducing power consumption. When the speed is reduced to this average speed, the control box 110 will start the motor 120 again. The motor 120 combines with the water flow to make the average speed of the rotary cart 220 reach 3.2rpm. When the speed of the rotary cart 220 is higher than the average speed, the control box 110 will control the speed of the rotary cart 220.

[0023] Of course, in order to use the generator module more conveniently, a circulating water pool can be built, and the mounting base 210 of the energy increase and decrease unit 200 can be set at the circulating water pool. The water hammer pump (not shown in the figure) in the energy increase and decrease unit 200 is used to lead the water in the lower part of the circulating water pool to a higher place, which is higher than the height of the rotary cart 220. The water in the higher place then flows downward through the pipeline into the force bucket 221 of the rotary cart 220, impacting it, thereby causing the rotary cart 220 to rotate, and combined with the motor 120 to drive the rotary cart 220 to rotate, thereby reducing the power consumption of the motor, thereby effectively reducing costs, improving the efficiency of the generator module, and making its comprehensive utilization value higher.

[0024] Finally, the motor 120 in this embodiment is a three-phase AC motor, and the rated power of the motor 120 is 5.5KW, while the generator 400 is a three-phase AC synchronous generator, or a DC generator with a DC-AC inverter, and the rated power of the generator 400 is at least 300KW.

[0025] In addition, the present invention also provides a power generation method of a self-powered generator module, comprising the following steps: S1, the mounting base 210 in the energy increase and decrease unit 200 is set at a river, stream or ditch, so that the rotary vehicle 220 is in the water flow, and then the motor 120 and the power amplifier 300 are respectively assembled with the rotary vehicle 220 to form a rotation connection, and the generator 400 is also assembled with the power amplifier 300 to form a rotation connection, and the transformer cabinet 500 is assembled and connected with the generator 400; S2. Start the control box 110 through an external power supply. The control box 110 drives the motor 120 to rotate. When the motor 120 rotates, it drives the wheel cart 220 to rotate, and cooperates with the water flow of rivers, streams or ditches to ensure the average speed of the wheel cart 220. The wheel cart 220 transmits the speed to the power amplifier 300, and the power amplifier 300 increases the speed to the set speed, and then transmits it to the corresponding generator 400. The generator 400 converts the mechanical energy into electrical energy, and transmits the electrical energy to the substation 500. The substation 500 then transmits the power to the transformer 600 and then connects it to the power grid, and a small part of the electrical energy is used for external power supply.

[0026] Specifically, during the operation, the energy increase and decrease unit 200 is first installed at a river, stream or ditch, and the water flow of the river, stream or ditch impacts the force bucket 221, so that the wheel 220 rotates, and then the motor 120 is started through the control box 110, and the motor 120 also drives the wheel 220 to rotate. Through the combination of the two, the power consumption of the motor 120 can be effectively reduced, thereby reducing costs, improving the efficiency of the generator module, and making its comprehensive utilization value higher. In addition, the control box 110 can also control the wheel The rotation speed of the car 220 is controlled to keep its average speed at 3.2rpm, and then combined with the power amplifier 300 to amplify its conversion to 117.2 times, thereby reaching the set standard speed of 375rpm, and then transmitted to the generator 400, the generator 400 converts the mechanical energy of the speed into electrical energy and outputs it to the substation 500, and then the substation 500 transmits it to the transformer 600 and directly connects it to the power grid, while a small part of the electrical energy can be used as an external power supply, and most of the electrical energy is output to the outside, thereby realizing self-circulating power generation.

[0027] Of course, in step S1, the mounting base 210 can also be set in a circulating water pool, and the circulating water from the lower part of the circulating water pool can be introduced to the higher part by a water hammer pump, and then the force bucket 221 of the rotary vehicle 220 is impacted from high to low through a pipeline to make the rotary vehicle 220 rotate.

[0028] By constructing a circulating water pool, the mounting base 210 of the energy increase and decrease unit 200 is set at the circulating water pool, and the water hammer pump in the energy increase and decrease unit 200 is used to lead the water in the lower part of the circulating water pool to a higher place, which is higher than the height of the rotary vehicle 220. The water in the higher place then flows downward through the pipeline to the force bucket 221 of the rotary vehicle 220, impacting it, so that the rotary vehicle 220 rotates, and combined with the motor 120 to drive the rotary vehicle 220 to rotate, which can also reduce the power consumption of the motor 120, thereby effectively reducing the cost, improving the efficiency of the generator module, and making its comprehensive utilization value higher.

[0029] The rated power of the motor 120 in this embodiment is 5.5KW, and the rated power of the generator 400 is 300KW, wherein the 5.5KW motor 120 consumes 5.5 degrees of electricity per hour, and combined with the energy increase and decrease unit 200 and the power amplifier 300, the generator 400 can generate 300 degrees of electricity per hour, wherein a small part of the electricity is used for external power supply, and most of the electricity can be output to the outside through the power grid. Finally, the motor 120 and the energy increase and decrease unit 200 are used to realize the conversion of small electric drive into larger electric energy, thereby reducing the cost of the generator module, improving the efficiency of the generator module, and making the comprehensive utilization value of the generator module higher.

[0030] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Any technician in this industry can smoothly implement the present invention as shown in the drawings of the specification and described above; however, any equivalent changes, modifications and evolutions made by any technician familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
