Description
Technical Field
The invention belongs to the technical field of wind energy generation, and particularly relates to a hydraulic energy conversion device for a bladeless wind turbine.
Background
Wind energy is a renewable and pollution-free energy source and has been highly valued by countries around the world. The wind energy is used for generating electricity, and is the main mode of wind energy utilization at present.
The basic principle of the wind turbine with the blades is that wind force acts on the blades of the wind wheel, so that the wind wheel is driven to rotate, the rotating speed is increased through a speed increaser, and then a generator is driven to generate electricity. The wind turbine with blades mainly comprises blades, a hub, a speed increaser, a generator, an iron tower, a tail rudder and the like, and is divided into a horizontal axis wind turbine and a vertical axis wind turbine. But has the defects of noise, visual pollution, high land occupation, ecological environment influence, high installation cost and the like.
A bladeless wind turbine has recently been proposed as a device for generating electricity from wind energy, the basic principle of which is to capture wind energy by vortex shedding effect and convert it into electric energy. Karman vortex is a common phenomenon in fluid mechanics, when a steady flow under certain conditions bypasses objects such as a high tower, a chimney, a telegraph pole and the like, two sides of the object periodically fall off double-line vortex with opposite rotation directions and regular arrangement, and the karman vortex street is formed after nonlinear action. Vortex shedding produces an alternating transverse force on the object that forces the structure of the object to vibrate regularly, with the frequency of vibration being proportional to the incoming flow velocity, and by maximizing the oscillation of the structure and capturing the mechanical energy, the mechanical energy can be used to generate electricity. The bladeless wind turbine has the advantages of low land occupation, no noise, environmental friendliness, high cost performance, low manufacturing cost and the like.
However, since the bladeless wind turbine device captures wind energy by forcing the structure to vibrate, i.e. the captured wind energy is reflected in the vibration frequency and amplitude of the structure of the object, if the captured wind energy is converted into electrical energy, the vibration frequency and amplitude obtained by the object need to be converted into rotational movement required by the generator, i.e. an energy conversion device is required. The hydraulic energy conversion device provided by the invention has the advantages of compact structure, no noise, convenience in maintenance, low manufacturing cost, no gear transmission, high energy conversion rate and the like, and can amplify the received frequency by two times.
Disclosure of Invention
In order to convert the vibration frequency and the vibration amplitude acquired by the object structure into the rotational kinetic energy, the invention provides the hydraulic energy conversion device which has a simple structure and is used for the bladeless wind turbine.
The technical scheme adopted for solving the technical problems is as follows: the device mainly comprises a wind power tower 1, a spherical hinge I2, an upper machine seat 3, a spherical hinge 4, a piston assembly 5, a cylinder body 6, a spherical hinge II 7, a lower machine seat 8, a one-way valve I10, a one-way valve II 11, a hydraulic pipe 9 and a hydraulic motor 12; the wind power tower 1 is fixed on the upper base 3 through a spherical hinge I2, the wind power tower 1 is connected with the piston assembly 5 through a spherical hinge 4, the piston assembly 5 is arranged in the cylinder body 6, and when the wind power tower 1 deflects and swings, the piston assembly 5 is driven to move up and down in the cylinder body 6, so that liquid in the cylinder body 6 is sucked and discharged; the cylinder body 6 is fixed on the lower base 8 through the spherical hinge II 7, one end of the hydraulic pipe 9 is connected to the cylinder body 6, the other end of the hydraulic pipe is divided into two branches which are respectively connected with the hydraulic motor through the one-way valve I10 and the one-way valve II 11, and when the piston assembly 5 moves up and down in the cylinder body 6, liquid in the cylinder body 6 enters and exits the hydraulic motor 12 through the hydraulic pipe 9 through the one-way valve I10 and the one-way valve II 11 respectively, so that an output shaft of the hydraulic motor 12 rotates.
The wind power tower 1 is fixed on the upper base 3 through a spherical hinge I2, and meanwhile, the wind power tower 1 is connected with the piston assembly 5 through a spherical hinge 4. When wind force F acts on the wind power tower 1, the wind power tower 1 is caused to deflect, and if the wind power tower rotates from the position A to the position B, the piston assembly 5 is driven to move upwards, so that the volume of the lower end of the cylinder body 6 is increased, and liquid is sucked from the hydraulic motor 12 through the hydraulic pipe 9 and the one-way valve II 11; under the periodic transverse alternating force of the karman vortex street, when the wind tower 1 returns to the position A from the position B, the piston assembly 5 is driven to move downwards, and hydraulic oil in the compression cylinder 6 returns to the hydraulic motor 12 through the hydraulic pipe 9 and the one-way valve I10; under the continuous action of the acting force, the wind tower 1 deflects from the position A to the position C, and drives the piston assembly 5 to move upwards, so that the cylinder body 6 generates a liquid sucking process; when the force drives the wind power tower 1 to return to the position A from the position C, the piston assembly 5 is driven to move downwards, and the cylinder body 6 finishes the process of discharging liquid once again; a similar process of sucking and discharging liquid is circulated so as to drive the rotation of the output shaft in the hydraulic motor 12, so as to achieve the conversion of the periodic oscillations generated by the wind tower 1 into the rotational kinetic energy of the hydraulic motor.
The wind power tower 1 is fixed on the upper support 3 through the spherical hinge I2, wherein the wind power tower 1 can only deflect around the upper support 3 and cannot rotate around the longitudinal axis of the wind power tower 1, so that the wind power generation device can prevent the wind power tower 1 from rotating under the action of wind power to consume the wind energy. The spherical hinge I2 is adopted to fix the wind power tower 1 on the upper support 3, so that the wind power direction accepted by the wind power tower 1 is not limited, and any wind power with the same direction can lead the wind power tower 1 to deflect at the same angle and output the same rotational kinetic energy. The spherical hinge I2 is adopted to fix the wind power tower 1 on the upper support 3, so that the installation of the bladeless wind power machine is not limited by the incoming flow direction.
The wind power tower 1 is directly connected with the piston assembly 5 through the ball head hinge 4, under the combined action of wind power and the periodic transverse alternating force of the karman vortex street, the vibration frequency and the amplitude generated by the wind power tower 1 are directly converted into the frequency and the movement amount of the up-and-down movement of the piston assembly 5, wherein the vibration frequency generated by the wind power tower 1 is converted into the up-and-down movement frequency of the piston assembly 5, and the up-and-down movement frequency of the piston assembly 5 is twice the vibration frequency of the wind power tower 1, so that the frequency amplification effect is achieved; the amplitude of the wind power tower 1 generated by the oscillation is converted into the amplitude of the up-and-down motion of the piston assembly 5, thereby realizing the suction or discharge of the liquid in the cylinder 6. When the wind force or wind speed increases, the larger the wind energy, the larger the angle of deflection of the wind power tower 1 is, namely the amplitude of the wind power tower 1 is increased, the amplitude of the up-and-down motion of the piston assembly 5 is also increased, and the liquid sucked or discharged from the cylinder 6 is increased, so that the rotation speed of the hydraulic motor 12 is also increased. Meanwhile, the wind power tower 1 is directly connected with the piston assembly 5 through the ball head hinge 4, so that intermediate links are effectively reduced, and energy loss in the wind power receiving process is reduced.
The wind power tower 1 is directly connected with the piston assembly 5 through the ball joint 4, wherein the piston assembly 5 can only deflect around the ball joint 4 and cannot rotate around the longitudinal axis of the piston assembly 5, on one hand, the piston assembly 5 can be prevented from rotating to cause abrasion and energy loss increase; on the other hand, when the wind power tower 1 deflects in a certain direction under the action of wind power, the piston assembly 5 can be ensured to correspondingly deflect in the opposite direction to the deflection of the wind power tower 1.
The cylinder 6 is directly fixed to the lower support 8 by means of a spherical hinge ii 7, wherein the cylinder 6 can only rotate around the lower support 8 and not around the longitudinal axis of the cylinder 6 itself. The spherical hinge II 7 can correspondingly deflect the cylinder body 6 in coordination with the deflection of the piston assembly 5, so that the energy loss is reduced as much as possible.
The cylinder body 6 is directly connected with the hydraulic motor 12 through the hydraulic pipe 9, the one-way valve I10 and the one-way valve II 11, when the cylinder body 6 sucks liquid, the liquid enters the cylinder body 6 through the hydraulic motor 12, the one-way valve II 11 and the hydraulic pipe 9, so that the suction process of the liquid in the cylinder body 6 is completed; when the cylinder 6 discharges the liquid, the liquid enters the hydraulic motor 12 from the cylinder 6, the hydraulic pipe 9 and the check valve I10, thereby completing the discharge process of the liquid in the cylinder 6. Meanwhile, the cylinder body 6 is directly connected with the hydraulic motor 12 through the hydraulic pipe 9, the one-way valve I10 and the one-way valve II 11, and on one hand, the suction and discharge processes of the liquid in the cylinder body 6 are converted into the rotation output of the hydraulic motor 12; on the other hand, the intermediate links can be effectively reduced, and the energy consumption in the energy conversion process is reduced.
The beneficial effects of the invention are as follows: when the hydraulic energy conversion device for the bladeless wind turbine is adopted, when transverse alternating force generated by wind power and karman vortex street acts on a wind power tower together, the wind power tower can generate continuous oscillation, and if the natural frequency of the wind power tower is close to the oscillation frequency, the oscillation of the wind power tower can be maximized, namely the wind power tower can obtain the maximum mechanical energy; because the wind power tower structure is directly connected with the piston assembly, mechanical energy obtained by the wind power tower can be directly converted into work applied to the piston assembly, and the larger the wind power is, the more the work is applied; on the other hand, the vibration frequency of the wind power tower during vibration can be directly converted into the up-and-down motion of the piston assembly, and the motion frequency of the piston assembly is twice that of the wind power tower, so that the amplification effect of the vibration frequency is achieved.
The hydraulic energy conversion device for the bladeless wind turbine is characterized in that the wind power tower is hinged with the upper support seat, the cylinder body is hinged with the lower support seat in a spherical mode, and the wind power tower is hinged with the piston assembly in a spherical mode, so that the wind power tower can receive wind power in any direction and generate oscillation in a corresponding direction through the rotation of the longitudinal axis of the wind power tower due to the fact that the wind power tower is hinged with the upper support seat and the cylinder body is hinged with the lower support seat, and the wind power tower can be prevented from being limited by the direction when the wind power of incoming flows is the same.
Because the hydraulic system is adopted in the invention, gear transmission is not generated between the conversion of mechanical energy and rotational kinetic energy, so that no noise is generated in the energy conversion process, the bladeless wind turbine is ensured not to generate noise pollution, and the bladeless wind turbine can be installed in a living area.
Finally, as the hydraulic energy conversion device for the bladeless wind turbine is compact in structure and small in energy loss, the manufacturing and mounting cost of the bladeless wind turbine can be greatly reduced, and the cost performance of the bladeless wind turbine is improved.

Detailed Description
The invention will be described in further detail with reference to the drawings and examples.
The embodiment 1 of the invention mainly comprises a wind power tower 1, a spherical hinge I2, an upper machine seat 3, a spherical hinge 4, a piston assembly 5, a cylinder body 6, a spherical hinge II 7, a lower machine seat 8, a one-way valve I10, a one-way valve II 11, a hydraulic pipe 9 and a hydraulic motor 12; the wind power tower 1 is fixed on the upper base 3 through a spherical hinge I2, the wind power tower 1 is connected with the piston assembly 5 through a spherical hinge 4, the piston assembly 5 is arranged in the cylinder body 6, and when the wind power tower 1 deflects and swings, the piston assembly 5 is driven to move up and down in the cylinder body 6, so that liquid in the cylinder body 6 is sucked and discharged; the cylinder body 6 is fixed on the lower base 8 through the spherical hinge II 7, one end of the hydraulic pipe 9 is connected to the cylinder body 6, the other end of the hydraulic pipe is divided into two branches which are respectively connected with the hydraulic motor through the one-way valve I10 and the one-way valve II 11, and when the piston assembly 5 moves up and down in the cylinder body 6, liquid in the cylinder body 6 enters and exits the hydraulic motor 12 through the hydraulic pipe 9 through the one-way valve I10 and the one-way valve II 11 respectively, so that an output shaft of the hydraulic motor 12 rotates. Reference is made to fig. 1 to 3.
In embodiment 2, the wind power tower 1 is fixed on the upper base 3 through the spherical hinge I2, and the wind power tower 1 can only rotate around the upper base 3 but not rotate around the longitudinal axis of the wind power tower 1, so that the wind power generation device can prevent the wind power tower 1 from rotating under the action of wind power to consume wind energy. The spherical hinge I2 is adopted to fix the wind power tower 1 on the upper support 3, so that the wind power direction accepted by the wind power tower 1 is not limited, and any wind power with the same direction can lead the wind power tower 1 to deflect at the same angle and output the same rotational kinetic energy. The spherical hinge I2 is adopted to fix the wind power tower 1 on the upper support 3, so that the installation of the bladeless wind power machine is not limited by the incoming flow direction. Referring to fig. 1 to 3, the rest is the same as embodiment 1.
In embodiment 4, the cylinder 6 is fixed on the lower base 8 through the spherical hinge ii 7, and the cylinder 6 can only deflect around the lower base 8 but cannot rotate around the longitudinal axis of the cylinder 6, and the spherical hinge ii 7 can correspondingly deflect the cylinder 6 in coordination with the deflection of the piston assembly 5, so that the energy loss is reduced as much as possible. Referring to fig. 1 to 3, the rest is the same as the above embodiment.
The working process of the invention is as follows: under the combined action of wind power and alternating transverse force generated by vortex street, the wind power tower 1 can generate periodic oscillation, and when the frequency of the acting force is close to the natural frequency of the wind power tower 1, the oscillation of the wind power tower 1 is maximized, namely the wind power tower 1 obtains the maximum mechanical energy; because the oscillation of the wind power tower 1 can cause the wind power tower 1 to generate a certain angle and to-and-fro deflection along the incoming flow direction, namely the wind power tower 1 turns from the position A to the position B, returns from the position B to the position A and returns from the position A to the position C and returns from the position C to the position A, thereby completing an oscillation period, and the cycle is completed, wherein the frequency of the oscillation is in direct proportion to the wind speed and the amplitude of the oscillation is in direct proportion to the wind power, so when the wind power is large and the wind speed is large, the frequency and the amplitude of the oscillation of the wind power tower 1 are both increased, and the energy acquired by the wind power tower 1, namely the mechanical energy, is also larger.
When the wind power tower 1 deflects from the position A to the position B, the piston assembly 5 is driven by the ball head hinge 4 to move upwards along the cylinder body 6, the volume of the lower end of the cylinder body 6 is increased, and liquid is sucked into the cylinder body 6 from the hydraulic motor 11 through the hydraulic pipe 9 and the one-way valve 11; when the wind power tower 1 reaches the position B, the wind power tower 1 is deflected to the position of the maximum angle against the resistance of the wind power tower, the piston assembly 5 does not move upwards any more, the volume of the lower end of the cylinder body 6 also reaches the maximum value, liquid is not sucked any more, and the cylinder body 6 completes the process of sucking liquid once. Under the pushing of acting force, the wind power tower 1 deflects from the position B to the position A, the wind power tower 1 drives the piston assembly 5 to move downwards along the inner wall of the cylinder body 6 through the ball head hinge 4, the volume of the lower end of the cylinder body 6 gradually becomes smaller, and the piston assembly 5 pushes liquid at the lower end of the cylinder body 6 to enter the hydraulic motor 12 through the hydraulic pipe 9 and the one-way valve 10; when the wind power tower 1 reaches the position A, the piston assembly 5 reaches the lowest end position of the piston assembly in the cylinder body 6, at the moment, the volume in the cylinder body 6 is not changed any more, namely reaches the minimum value, and the liquid is not flowed any more, so that the cylinder body 6 completes the primary liquid discharging process; at this time, the wind power tower 1 completes the oscillation of half period, and the piston assembly 5 and the cylinder body 6 cooperate to complete the process of one-time suction and discharge, namely, the liquid passes through one cycle operation, and the liquid enters and exits in the hydraulic motor, so as to drive the output shaft in the hydraulic motor to rotate, namely, the conversion from the oscillation acquired by the wind power tower 1, namely, the mechanical energy to the rotational kinetic energy is realized.
When the wind power tower 1 deflects from the position A to the position C, the piston assembly 5 is driven by the ball head hinge 4 to move upwards along the cylinder body 6, at the moment, the volume of the lower end of the cylinder body 6 is increased again, and liquid is sucked into the cylinder body 6 again from the hydraulic motor 11 through the hydraulic pipe 9 and the one-way valve 11; when the wind power tower 1 reaches the position C, the wind power tower 1 is deflected to the position of the maximum angle, the piston assembly 5 does not move upwards any more, the volume at the lower end of the cylinder body 6 reaches the maximum value again, liquid is not sucked any more, and the cylinder body 6 completes the suction process of liquid again. Under the pushing of acting force, the wind power tower 1 deflects from the position C to the position A, drives the piston assembly 5 to move downwards along the cylinder body 6, and pushes liquid at the lower end of the cylinder body 6 to enter the hydraulic motor 12 through the hydraulic pipe 9 and the one-way valve 10; when the wind power tower 1 returns to the position A, the piston assembly 5 does not move downwards any more, the volume in the cylinder body 6 does not change any more, namely reaches the minimum value, and the liquid does not flow any more, so that the cylinder body 6 completes the primary liquid discharging process again; at this time, the wind power tower 1 completes the oscillation of half period, and the piston assembly 5 and the cylinder 6 complete the process of one-time suction and discharge, namely, the liquid is repeatedly circulated again, so as to push the liquid to circularly enter and exit in the hydraulic motor, and further drive the rotation of the output shaft in the hydraulic motor, so that the conversion from the oscillation, i.e. the mechanical energy, acquired by the wind power tower 1 to the rotational kinetic energy is realized.
Meanwhile, when the wind power tower 1 completes one period of oscillation, the cylinder body 6 completes the suction and discharge of liquid for 2 times, so that the device of the invention realizes the frequency amplification effect. When the wind force increases, the deflection generated by the wind tower 1 increases accordingly, so that the liquid sucked and discharged in the cylinder 6 increases, the acting force driving the hydraulic motor 12 increases, and the rotational speed of the output shaft of the hydraulic motor 11 increases. Conversely, when the wind force decreases, the deflection angle of the wind power tower 1 decreases, and the liquid sucked and discharged into and from the cylinder 6 decreases accordingly, so that the rotational speed of the output shaft of the hydraulic motor 12 decreases.
In addition, in the mechanism design, although a spherical hinged connection mode is adopted, the rotation of the wind power tower 1, the piston assembly 5 and the cylinder body 6 around the longitudinal axis of the wind power tower is limited, so that when the wind power tower 1 deflects under the action of incoming flow in any direction, the piston assembly 5 and the cylinder body 6 can correspondingly deflect according to the deflection direction of the wind power tower 1, and the energy consumption of the device in the energy transmission process is reduced to the minimum.
