Description

Technical Field

[0001] The present invention relates to the field of wind turbine power generation equipment, and in particular to equipment and a control method for increasing the power generation efficiency of a wind turbine based on fluid kinetic energy. Background Art

[0002] As a direct conversion of wind energy to electrical energy, wind power generation has been focused on by some countries and regions because it does not require fuel consumption and makes rational use of natural resources. As the basic equipment for wind power generation, wind turbines can effectively convert air kinetic energy into blade kinetic energy, and through the rotation of the blades of the wind turbine, the kinetic energy of the rotation is converted into electrical energy, thereby utilizing the kinetic energy of the air to reduce the consumption of fuel resources such as coal and achieve the purpose of energy conservation and emission reduction. The more common wind power generation equipment currently used includes horizontal axis wind turbines and vertical axis wind turbines. Because horizontal axis wind turbines are larger and have higher site requirements, they need to be installed in very open plains and hilly areas, so the most widely used wind power generation equipment is the application of vertical axis wind turbines.

[0003] A vertical axis wind turbine has a rotor whose axis of rotation is perpendicular to the ground or the direction of airflow. There are several types of vertical axis wind turbines that use resistance to rotate, including rotors made of flat plates and cups, such as S-shaped windmills, which have partial lift, but are mainly resistance devices. These devices have a large starting torque, but a low tip speed ratio. Under the condition of a certain rotor size, weight and cost, the power output provided is low. As for the advantages of vertical axis wind turbines, there is no need to face the wind when the wind direction changes. This is a major advantage over horizontal axis wind turbines. It not only simplifies the structural design, but also reduces the gyroscopic force of the rotor facing the wind. However, the existing problems are also mentioned above, that is, the power generation capacity is small, which limits the power generation effect of vertical axis wind turbines, thus limiting the application of vertical axis wind turbines.

[0004] Based on the above problems, it is necessary to set up equipment and control methods for increasing the power generation efficiency of wind turbines based on fluid kinetic energy. Such equipment and control methods can be set according to the power generation conditions of vertical-axis wind turbines so that the power generation efficiency of vertical-axis wind turbines can be increased while ensuring that they have better power generation stability to meet the needs of normal power generation. Summary of the invention

[0005] The purpose of the present invention is to provide a device and a control method for increasing the power generation efficiency of a wind turbine based on fluid kinetic energy. The device can be set according to the power generation situation of a vertical axis wind turbine so that the power generation efficiency of the vertical axis wind turbine can be increased while ensuring that it has better power generation stability to meet the normal power generation requirements.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] The device for increasing the efficiency of wind power generation based on fluid kinetic energy comprises a generator body and a fan blade, wherein the fan blade is cooperatively connected with the generator body; comprises a detection fixed end, an action member body, and a control system; the control system is data-connected with the detection fixed end;

[0008] Detection fixed end: including a fixed end and a tension detection component, the fixed end is matched with the fan blade, and the tension detection component is arranged at the matching connection position between the action member body and the fixed end, and the tension detection component is used to detect the force of the action member body on the fixed end;

[0009] The main body of the action member includes a flexible action member, which is made of soft and flexible material. After the two fixed ends are respectively matched with the adjacent fan blades, the two ends of the flexible action member are matched and connected with the two fixed ends.

[0010] An end slide groove is arranged on the fan blade to cooperate with the fixed end, and the opening direction of the end slide groove is arranged along the extension direction of the arc surface of the fan blade, and the fixed end is arranged in the end slide groove; an end circuit sensing group is arranged in the end slide groove to cooperate with the fixed end, and the position of the fixed end in the end slide groove is identified by the end circuit sensing group.

[0011] The terminal circuit sensing group includes multiple contact potentials, and the multiple contact potentials are arranged at equal intervals on both sides of the interior of the terminal slide, and the multiple contact potentials on one side are connected to the same circuit, and the connected circuit is connected to the control system; when the fixed terminal is inside the terminal slide, and both sides of the fixed terminal are in contact with the contact potentials on both sides of the terminal slide, a closed loop is formed between the fixed terminal and the control system.

[0012] The tension detection component is a tension sensor, the outer end surface of the fixed end head is a movable end surface, the tension sensor is arranged inside the fixed end head, and the outer end surface is connected to the movable end surface of the fixed end head.

[0013] A position driving component is arranged in the end slide slot, and the position driving component cooperates with the fixed end, and the position of the fixed end in the end slide slot is adjusted by the position driving component.

[0014] The main body of the actuator includes a plurality of flexible traction belts, and the flexible traction belts are filled with fluid; the fluid filled in the flexible traction belts is a non-Newtonian fluid.

[0015] The plurality of flexible traction belts are arranged in a spiral structure.

[0016] A control method for a device for increasing the efficiency of wind turbine power generation using fluid kinetic energy comprises the following steps:

[0017] S1, when the generator as a whole is not rotating, the position drive assembly drives the fixed end to move the position so that the fixed end is at the innermost position of the end slide slot;

[0018] S2, when the fan blades of the vertical axis wind turbine are driven to rotate under the action of wind force, the control system detects the rotation of the fan blades, thereby controlling the position driving component to drive the fixed end to move the position;

[0019] S3, at the same time, the tension detection component detects the tension applied by the main body of the actuator and transmits it to the control system, and combines the position information transmitted by the end circuit sensing group, so that the control system calculates according to the transmitted information and the circular motion formula to determine the kinetic energy of the main body of the actuator at this time;

[0020] S4, when the fan blades rotate with a certain kinetic energy, the position drive component releases the restriction on the main body of the actuator, so that the main body of the actuator moves along the end slide groove under the action of the force and slides to the outer end position of the end slide groove, thereby reaching the starting state of the vertical axis wind turbine;

[0021] S5, when the control system detects that the power generation efficiency of the wind turbine decreases, the main body of the action member applies the kinetic energy stored in itself to the fan blades, so that the fan blades can obtain kinetic energy. The main purpose of this setting is to ensure that the fan blades do not stagnate due to insufficient force during the process of wind force decreasing in the first stage;

[0022] S6, when the kinetic energy of the main body of the actuator is exhausted, the control system detects that the power generation efficiency of the vertical axis generator decreases and disappears, and the control system controls the position driving component to make the position driving component pull the main body of the actuator to move the main body of the actuator to the inner end position of the end slide groove;

[0023] S7, when the control system detects that the vertical axis generator generates power, the above steps S1-S6 are repeated to complete the power generation operation of the vertical axis wind turbine.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] When the device is set up, the power generation efficiency of the wind turbine is increased by cooperating with the fan blades to detect the fixed end and the setting of the action part body.

[0026] The detection fixed end is used in conjunction with the main body of the effector. When the vertical axis wind turbine is acted upon by an external force, it will rotate normally, and during the rotation process, it will drive the main body of the effector to rotate synchronously. When the main body of the effector rotates, a force will be applied to the detection fixed end. When the gravity is excluded, a traction force will be applied to the detection fixed end. The traction force provides the centripetal force of the main body of the effector to satisfy the circular motion of the main body of the effector. At this time, the radius of the circular motion of the main body of the effector increases, so that the linear velocity of the main body of the effector increases, thereby increasing the centripetal force of the fan blade as a whole. However, due to the traction problem of the main body of the effector, a part of the force will be extended along the tangent direction of the circular motion, so that the overall rotation effect of the fan blade is enhanced. And after the main body of the effector is set, the overall mass of the fan blade increases and the kinetic energy is enhanced, so the effect of converting electric energy is also increased, thereby achieving the effect of increasing the efficiency of the generator.

[0037] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0038] Because when the vertical axis wind turbine is driven, the wind force is needed to drive the fan blades 2 to rotate, so that the generator body 1 rotates while the kinetic energy of the rotation is converted into electrical energy through the generator, thereby achieving the purpose of power generation. However, when the existing vertical axis generator is generating electricity, because the contact area between the fan blades 2 and the wind direction is small, the fan blades 2 cannot effectively withstand the wind force, and thus the wind effect is not as good as the horizontal axis wind turbine. Moreover, there is another more important problem. Because the fan blades 2 of the vertical axis generator are small, it is more difficult to initially drive the vertical axis generator, that is, to overcome the initial resistance of the generator in order to ensure the normal rotation of the blades of the vertical axis wind turbine, so as to achieve the purpose of effectively rotating and generating electricity from the vertical axis wind turbine. Therefore, for the present invention, the following structural settings are made:

[0039] The device for increasing the efficiency of wind turbine power generation based on fluid kinetic energy includes a generator body 1 and a fan blade 2, wherein the fan blade 2 is connected to the generator body 1; this is a basic structural setting for a vertical axis wind turbine, and no further explanation is given here. The device includes a detection fixed end, an action member body 5, and a control system; the control system is connected to the detection fixed end by data; the control system provided here is used to perform data recognition and control on the circuit elements included in the detection fixed end, so that the device can achieve the purpose of intelligence.

[0040] Detection fixed end: including a fixed end 3 and a tension detection component 4, wherein the fixed end 3 cooperates with the fan blade 2, and the tension detection component 4 is arranged in cooperation with the connecting position of the action member body 5 and the fixed end 3, and the tension detection component 4 detects the force of the action member body 5 on the fixed end 3;

[0041] The action member body 5 includes a flexible action member, which is made of soft and flexible material. After the two fixed ends 3 are respectively matched with the adjacent fan blades 2, the two ends of the flexible action member are matched and connected with the two fixed ends 3.

[0042] When the wind force is applied to the fan blade 2 of the vertical axis generator, the fan blade 2 rotates and drives the flexible action member of the action member body 5 to rotate. When the flexible action member rotates with the fan blade 2, the force analysis of the action member body 5 and the fan blade 2 is performed in this state as shown in the attached figure of the specification. Figure 4 As shown,

[0043] That is, the fan blades 2 drive the main body 5 of the actuator to rotate:

[0044] F1 = F pull cos α;

[0045] In this state, the fan blades 2 are required to drive the action member body 5 to rotate, so that the action member body 5 stores a certain amount of kinetic energy;

[0046] When the external force acting on the fan blade 2 is reduced, or when the external force resistance is large, the force analysis of the action member body 5 and the fan blade 2 is performed in this state as shown in the accompanying figure of the specification. Figure 5 As shown,

[0047] F2 = F pull cosβ;

[0048] In this state, the main body 5 of the action member applies the kinetic energy stored in itself to the fan blades 2, so that the fan blades 2 can obtain kinetic energy. The main purpose of this setting is to ensure that the fan blades 2 will not stagnate due to insufficient force during the process of wind force reduction in the first stage, thereby affecting the normal rotation of the wind blades. And after the main body 5 of the action member is set, the overall mass of the fan blades 2 becomes larger, so when the fan blades 2 are in a stable rotation state, the main body 5 of the action member and the fan blades 2 are in a relatively static state, and the main body 5 of the action member will not cause an obstructive force to the normal rotation of the fan blades 2, thereby avoiding the setting of the main body 5 of the action member affecting the normal rotation of the fan blades 2. However, it should be noted here that when the fan blades 2 rotate as a whole, the overall mass of the fan blades 2 increases due to the increase of the main body 5 of the action member. In this case, the initial rotation of the fan blades 2 will be more difficult. Therefore, the following structural settings are made:

[0049] An end slot 6 is provided on the fan blade 2 to cooperate with the fixed end 3, and the opening direction of the end slot 6 is provided along the arc extension direction of the fan blade 2, and the fixed end 3 is provided in the end slot 6; an end circuit sensing group is provided in the end slot 6 to cooperate with the fixed end 3, and the position of the fixed end 3 in the end slot 6 is identified by the end circuit sensing group. After the end slot 6 is provided, it means that the distance of the fixed end 3 close to the generator body 1 can be changed, so in the initial rotation state of the vertical axis wind turbine, the fixed end 3 is close to the generator body 1, that is, the radius size in the circular motion is reduced, so that the linear speed of the action member body 5 during the rotation process is smaller, so that the kinetic energy required by the action member body 5 when the fan blade 2 rotates is reduced, thereby avoiding the influence of the initial start of the generator due to the setting of the action member body 5. Therefore, after the end slot 6 is provided, the problem as shown in the attached figure of the specification will not occur. Figure 4 The motion state shown in the figure will appear as shown in the specification Figure 6 In the motion state shown, compared with the former, the latter has the smallest kinetic energy obtained by the main body 5 of the action member during the generator startup process, and has the smallest effect on the normal rotation of the fan blades. When the generator is running normally, in order to enable the main body 5 of the action member to obtain more kinetic energy, the fixed end 3 can be placed at the outermost position of the end slide slot 6, so that the main body 5 of the action member can obtain greater power to meet the effect.

[0050] For determining the specific position of the fixed terminal 3 in the terminal slot 6, the terminal circuit sensing group includes a plurality of contact potentials 7, which are arranged at equal intervals on both sides of the interior of the terminal slot 6, and the plurality of contact potentials 7 on one side are connected to the same circuit, and the connected circuit is connected to the control system; when the fixed terminal 3 is in the terminal slot 6, and both sides of the fixed terminal 3 are in contact with the contact potentials 7 on both sides of the terminal slot 6, a closed loop is formed between the fixed terminal 3 and the control system. As shown in the accompanying drawings of the specification Figure 7 As shown, the specific position of the fixed end 3 in the end slide slot 6 can be determined based on the detection information of the control system. In order to realize the automatic adjustment of the fixed end 3 in the end slide slot 6, the tension detection component 4 is a tension sensor 8, the outer end surface of the fixed end 3 is a movable end surface, and the tension sensor 8 is arranged inside the fixed end 3, and the outer end surface is connected to the movable end surface of the fixed end 3.

[0051] The above-mentioned control method is as follows: when the generator as a whole is not rotating, the position drive component drives the fixed end 3 to move its position, so that the fixed end 3 is at the innermost position of the end slide slot 6; when the blades of the wind turbine generator are driven to rotate under the action of wind force, the control system detects that the fan blades 2 are rotating, thereby controlling the position drive component so that the position drive component drives the fixed end 3 to move its position; at the same time, the tension detection component 4 detects the tension applied by the action member body 5 and transmits it to the control system, and combines the position information transmitted by the end circuit sensing group so that the control system calculates according to the transmitted information and the circular motion formula to determine the kinetic energy of the action member body 5 at this time; when the fan blades 2 rotate with a certain kinetic energy, the position drive component releases the restriction on the action member body 5, so that the action member body 5 moves along the end slide slot 6 under the action of the force, and slides to the outer end position of the end slide slot 6, thereby reaching the starting state of the vertical axis wind turbine. For the position drive component set here, the traditional traction rod drive method can be selected for setting, but it needs to meet the setting requirements in the end slide groove 6, which will not be explained in detail here.

[0052] As for the setting of the main body 5 of the action member, its specific structure is as follows:

[0053] The action member body 5 includes a plurality of flexible traction belts 9, and the flexible traction belts 9 are filled with fluid; the fluid filled in the flexible traction belts 9 is a non-Newtonian fluid, that is, to avoid the water hammer effect of the flexible traction belts 9 caused by traditional fluids, which may cause damage to the vertical axis fan blades. At the same time, the plurality of flexible traction belts 9 are arranged in a spiral structure to reduce the influence of the action force between the plurality of flexible traction belts 9, because the spiral arrangement can buffer the action force, thereby avoiding the problem of inconsistent action of the flexible traction belts 9.

[0054] A control method for a device for increasing the efficiency of wind turbine power generation based on fluid kinetic energy comprises the following steps:

[0055] S1, when the generator as a whole is not rotating, the position driving assembly drives the fixed end 3 to move the position so that the fixed end 3 is at the innermost position of the end slide slot 6;

[0056] S2, when the fan blades 2 of the vertical axis wind turbine are driven to rotate under the action of wind force, the control system detects the rotation of the fan blades 2, thereby controlling the position driving component to drive the fixed end 3 to move the position;

[0057] S3, at the same time, the tension detection component 4 detects the tension applied by the actuator body 5 and transmits it to the control system, and combines the position information transmitted by the end circuit sensing group, so that the control system calculates according to the transmitted information and the circular motion formula to determine the kinetic energy of the actuator body 5 at this time;

[0058] S4, when the fan blades 2 rotate with a certain kinetic energy, the position driving component releases the restriction on the actuator body 5, so that the actuator body 5 moves along the end slide groove 6 under the action of the force and slides to the outer end position of the end slide groove 6, thereby reaching the starting state of the vertical axis wind turbine;

[0059] S5, when the control system detects that the power generation efficiency of the wind turbine decreases, the action member body 5 applies the kinetic energy stored in itself to the fan blades 2, so that the fan blades 2 can obtain kinetic energy. The main purpose of this setting is to ensure that the fan blades 2 do not stagnate due to insufficient force during the process of wind force decreasing in the first stage.

[0060] S6, when the kinetic energy of the actuator body 5 is exhausted, the control system detects that the power generation efficiency of the vertical axis generator decreases and disappears, and the control system controls the position driving component to make the position driving component pull the actuator body 5 to move the actuator body 5 to the inner end position of the end slide groove 6;

[0061] S7, when the control system detects that the vertical axis generator generates power, the above steps S1-S6 are repeated to complete the power generation operation of the vertical axis wind turbine.

[0062] Therefore, the setting of equipment and control methods for increasing the power generation efficiency of wind turbines based on fluid kinetic energy can be set according to the power generation conditions of vertical-axis wind turbines, so that the power generation efficiency of vertical-axis wind turbines can be increased, while ensuring that they have better power generation stability to meet the needs of normal power generation.
