Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 5, a bladeless wind power generation apparatus based on the galloping principle according to an embodiment of the present invention will be described. The bladeless wind power generation device based on the galloping principle comprises a support 100, a main vibrator 200 and a power generation vibrator 500.
The main vibrator 200 is a hollow prism horizontally disposed, and both ends are connected to the bracket 100 through the first elastic member 300, respectively. Two magnets 400 are disposed in parallel and opposite to each other in the cavity of the main vibrator 200. A horizontal magnetic induction line is formed between the two magnets 400.
The generating vibrator 500 is located between the two magnets 400. The generating vibrator 500 includes a conductor 510 and a second elastic member 520 connecting the conductor 510 and the inner wall of the main vibrator 200. Both ends of the conductor 510 are used for electrical connection with the battery pack, respectively.
When the main vibrator 200 is subjected to transverse wind and galloping occurs, the conductor 510 bounces up and down relative to the magnet 400 under the combined action of the inertia force and the second elastic member 520, and the horizontal magnetic induction lines are cut back and forth to realize power generation.
For convenience of description, the following section will simply refer to "bladeless wind power plant based on the galloping principle" as a power plant.
When the wind power generation device is used, the power generation device is placed in a windy place, two ends of the conductor 510 are respectively electrically connected with the storage battery pack, when the main vibrator 200 is acted by transverse wind, the transverse flow galloping phenomenon can occur, the main vibrator does up-and-down bouncing non-uniform motion, the conductor 510 in the power generation vibrator 500 in the main vibrator 200 does up-and-down reciprocating motion relative to the main vibrator 200 under the action of inertia force and the second elastic piece 520, and horizontal magnetic induction lines generated by two magnets 400 in the main vibrator 200 are cut in a reciprocating mode, so that power generation is realized. The generated electric energy is stored by the storage battery pack.
The invention is provided based on the transverse wind direction relaxation vibration principle (namely the transverse flow relaxation vibration principle) and the electromagnetic induction effect principle, wherein the transverse wind direction relaxation vibration principle refers to the unstable vibration of a slender structure caused by aerodynamic negative damping components generated by flow separation and vortex shedding. Transverse wind direction galloping is a divergent bending self-excited vibration caused by the negative slope of the lift curve. The negative slope enables the displacement of the structure in the vibration process to be consistent with the direction of the air force all the time, and the structure continuously absorbs energy from the outside, so that unstable vibration is formed. With the present embodiment, the main vibrator 200 absorbs energy from the outside when receiving transverse wind, and moves up and down at a non-uniform speed under the action of the transverse wind and the first elastic member 300, and the conductor 510 moves up and down at a non-uniform speed in the inner cavity of the main vibrator 200 relative to the main vibrator 200 under the action of the inertia force and the second elastic member 520, so as to repeatedly cut the horizontal magnetic induction lines generated by the two magnets 400, thereby realizing the conversion from wind energy to electric energy.
In order to verify the feasibility of the scheme of the embodiment, the inventor carries out a wind tunnel test, the wind tunnel test is carried out in a low-speed section of a wind tunnel laboratory STU-1 of an atmospheric boundary layer wind tunnel center of wind engineering research center of Shijiazhuang railway university, the wind speed can reach 30.0m/s at most, the turbulence degree of a test section region is not more than 0.5%, the speed instability is less than 1%, and the deflection angle of average airflow is less than 1 deg.
DenHartog considers that the vertical vibration of the model causes the change of the model relative to the wind attack angle of the incoming flow so as to cause the aerodynamic force to change, when the change of the aerodynamic force causes the damping of the system to become a negative value sometimes, the system is in an unstable state, namely the system comprises structural damping and aerodynamic damping when the vertical vibration occurs, the vertical vibration occurs when the sum of the two is a negative value, and the larger the absolute value of the negative value is, the more easily the vertical vibration occurs to the model, and the vibration becomes divergent vibration because the total damping of the system is a negative value. DenHartog proposes a DenHartog galloping criterion, and the transverse wind direction galloping occurs and the coefficient is more obvious as the following formula model is satisfied.
The galloping coefficient of the model can be obtained through a wind tunnel test, the test wind speeds are three wind speeds of 5m/s, 10m/s and 15m/s, the lift coefficient and the drag coefficient are almost the same at the three wind speeds, and the galloping coefficient of the structure is smaller than 0 and is the smallest near 0 degrees and +/-14 degrees under a wind direction angle of-14 degrees to 14 degrees as can be seen from a graph 5.
According to the test results, the main oscillator 200 can generate relaxation oscillation within the wind direction angle range of-14 degrees to 14 degrees, and the main oscillator 200 is horizontally arranged in the embodiment, that is, the bladeless wind power generation equipment based on the relaxation oscillation principle provided by the embodiment is easy to generate relaxation oscillation when being subjected to transverse wind, so that the feasibility of power generation is ensured.
Compared with the prior art, the bladeless wind power generation equipment based on the galloping principle changes the power generation principle of the wind power generation equipment, and provides green and environment-friendly bladeless wind power generation equipment. The transverse wind direction galloping principle is utilized to convert wind energy into kinetic energy of the main vibrator 200 and the generating vibrator 500, the electromagnetic induction effect is utilized to convert the kinetic energy of the generating vibrator 500 into electric energy, and the conversion from the wind energy to the electric energy is realized. According to the scheme, wind power generation is achieved without the aid of blades, the whole equipment is simple in structure, convenient and fast to maintain, free of adverse effects on the ecological environment and convenient to popularize, the defects of traditional wind power generation can be avoided to a great extent, the development prospect is wide, and relevant equipment does not exist in China.
