Description

Technical Field

[0001] This utility model relates to the field of generator testing technology, and in particular to a small integrated system for wind power generation and wind speed testing. Background Technology

[0002] Small wind turbines, as an important form of renewable energy, can convert wind energy into electricity, offering advantages such as being green, environmentally friendly, and low-carbon. Their low starting wind speed, easy installation, and low maintenance costs make them an ideal choice for addressing localized power needs. Existing technologies, such as the small wind turbine disclosed in CN202320633134.1, use a driving and driven spur gear to transmit wind turbine torque to the generator for power generation. By setting an appropriate speed ratio through the gear transmission system, the generator rotor speed is increased, thereby improving power generation efficiency under low wind conditions. However, this patented technology, like most generators, uses a one-piece molded design for the casing, making it difficult to observe the internal transmission mechanism and preventing the gear train from being replaced to adjust the transmission ratio. Therefore, there is an urgent need for an integrated power generation and wind speed testing system that can visually display the generator's structure and allows for adjusting the transmission ratio by changing the gear train under different wind speed conditions, ensuring optimized power generation efficiency while maintaining the identified speed. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and to provide an integrated power generation and wind speed testing system that can intuitively display the composition structure of the generator and allow the transmission ratio to be adjusted by changing the gear train under different wind speed conditions, so as to ensure that the generator optimizes the power generation efficiency while reaching the identified speed.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A small-scale integrated wind power generation and wind speed testing system includes a testing platform. The testing platform is equipped with an electrical control box and a power generation device. The power generation device includes a base, a generator, a transmission device, and an impeller. The base is fixedly mounted on the top surface of the testing platform, and the generator is fixedly supported by the base. The transmission device connects the generator and the impeller. The electrical control box is fixedly connected to the testing platform. The electrical control box contains a voltage detection relay, a light bulb, an ammeter, a voltmeter, and an air switch. The normally open terminal of the voltage detection relay is connected to the generator, and the common terminal of the voltage detection relay is connected to the light bulb. The ammeter is connected in series with the generator, and the voltmeter is connected in parallel with the generator. The air switch is connected to the voltage detection relay.

[0006] Furthermore, the transmission device includes an open housing, an output shaft, a driven gear, an input shaft, a driving gear, and a rigid coupling. The output shaft and the input shaft are both located inside the housing. The output shaft is connected to the generator. The driven gear is located on the output shaft. The driving gear is located on the input shaft and meshes with the driven gear. The rigid coupling is located outside the housing and is connected to one end of the input shaft. The other end of the rigid coupling is connected to the impeller through an impeller coupling.

[0007] Furthermore, the outer casing is composed of symmetrically arranged connecting plates and outer side plates. One end of the connecting plate is fixedly connected to the base, and a support column is fixedly connected between the other end of the connecting plate and the outer side plate. The end of the output shaft connected to the generator extends out of the connecting plate, and the rigid coupling is located outside the outer side plate.

[0008] Furthermore, the lower limit voltage values ​​of the voltage detection relay are 5V, 12V and 24V, and three bulbs are provided, each corresponding to one of the three lower limit voltage values.

[0009] Furthermore, the impeller is provided with a flow guide.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The power generation device of this invention is designed in an open manner, allowing for real-time adjustment of the generator's transmission ratio by changing the gear train, thus adapting to different wind speed conditions and improving the power generation efficiency of the wind turbine. Furthermore, by integrating wind speed measurement and power generation performance testing, the performance evaluation and adjustment of the wind turbine can be conveniently performed, enhancing the applicability and maintainability of the equipment, making it particularly suitable for experimental research.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 4 As shown, a small-scale integrated wind power generation and wind speed testing system includes a test platform 3. The test platform 3 is equipped with an electrical control box 1 and a power generation device 2. The power generation device 2 includes a base 21, a generator 22, a transmission device 23, and an impeller 24. The base 21 is fixedly mounted on the top surface of the test platform 3, and the generator 22 is fixedly supported by the base 21. The transmission device 23 connects the generator 22 and the impeller 24. The housing 14 of the electrical control box 1 is fixedly connected to the test platform 3. The electrical control box 1 contains a voltage detection relay 15, a light bulb 13, an ammeter 16, a voltmeter 17, and an air switch 12. The normally open terminal of the voltage detection relay 15 is connected to the generator 22, and the common terminal of the voltage detection relay 15 is connected to the light bulb 13. The ammeter 16 is connected in series with the generator 22, and the voltmeter 17 is connected in parallel with the generator 22. The air switch 12 is connected to the voltage detection relay 15.

[0020] The transmission device 23 includes an open housing, an output shaft 233, a driven gear 234, an input shaft 239, a driving gear 238, and a rigid coupling 236. The output shaft 233 and the input shaft 239 are both located inside the housing. The output shaft 233 is connected to the generator 22. The driven gear 234 is located on the output shaft 233. The driving gear 238 is located on the input shaft 239 and meshes with the driven gear 234. The rigid coupling 236 is located outside the housing and is connected to one end of the input shaft 239. The other end of the rigid coupling 236 is connected to the impeller 24 through an impeller coupling 237. The open housing facilitates the replacement of the drive gear 238 and driven gear 234 during testing to adjust the transmission ratio. The housing consists of a symmetrically arranged connecting plate 231 and an outer plate 235. One end of the connecting plate 231 is fixedly connected to the base 21, and a support column 232 is fixedly connected between the other end of the connecting plate 231 and the outer plate 235. The end of the output shaft 233 connected to the generator 22 extends out of the connecting plate 231, and the rigid coupling 236 is located outside the outer plate 235.

[0021] During testing, the impeller 24 rotates under the influence of wind speed, transmitting the converted mechanical energy to the generator 22 via the driving gear 238 and the driven gear 234. Because the transmission device 23 has an open structure, it facilitates observation of the internal structure of the generator 22 during the test. Furthermore, the transmission ratio can be adjusted by changing the gear train under different wind speed conditions to optimize power generation efficiency while ensuring the generator 22 reaches the identified rotational speed. Moreover, the voltage detection relay 15 in the control box 1 can detect the output voltage of the generator 22 in real time and control the circuit's on / off state according to the set lower limit voltage value, thereby adjusting the connection between the generator 22 and the bulb 13 circuit, achieving real-time monitoring of the generator 22's power generation capacity. During monitoring, the air switch 12 ensures that the voltage detection relay 15 can control the circuit's on / off state according to wind speed changes, enabling real-time monitoring and adjustment of the generator 22.

[0022] The voltage detection relay 15 has lower limit voltage values ​​of 5V, 12V, and 24V, and three bulbs 13 are provided, each corresponding to one of the three lower limit voltage values. When the generator 22 output voltage reaches the set lower limit value, the voltage detection relay 15 closes, controlling the current to flow to the bulb 13 circuit, making it easy to observe the lighting status of the bulb 13, thereby reflecting the power generation capacity of the generator 22 and realizing the dynamic testing of the wind turbine.

[0023] The working principle of this utility model is as follows: the voltage detection relay 15, ammeter 16, and voltmeter 17 are powered by the power supply in the electrical control box 1. When the wind speed changes, the transmission device 23 drives the generator 22 to rotate through the impeller 24, outputting voltage and current. The voltage detection relay 15 detects the voltage of the generator 22 in real time and compares it with the set lower limit voltage value. When the voltage reaches the set lower limit value, the voltage detection relay 15 closes, and the current and voltage through the bulb 13 are monitored by the ammeter 16 and voltmeter 17. The voltage detection relay 15 controls the on / off state of the bulb 13 circuit. By observing the on / off state of the bulb 13, the power generation capacity of the generator 22 can be intuitively understood.

[0024] The impeller 24 is equipped with a flow guide 25, which can reduce wind resistance and make the test data more accurate.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
