Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and particularly to a low-wind power generation device based on the scenario of highway tunnels. Background Art

[0002] With the increasingly severe global energy crisis and the continuous enhancement of environmental protection awareness, the development and utilization of renewable energy have received more and more attention. One of the main manifestations of the global energy crisis is the scarcity of traditional energy resources such as oil and natural gas. Renewable energy sources such as solar energy, wind energy, and hydropower energy, with their rich resources, clean characteristics, and sustainable advantages, are considered effective ways to solve energy problems. Wind energy, as a clean and renewable energy source, has developed rapidly in recent years. Traditional wind power generation devices usually require relatively high wind speeds to start and operate, which greatly limits their application scope. Especially in some areas with low wind speeds or seasonal wind deficiencies, traditional wind turbines often cannot work properly, resulting in low utilization efficiency of wind energy resources.

[0003] The emergence of low-wind power generation technology has broadened the application scope of wind power generation, enabling this technology to be used for power generation in areas with relatively scarce wind energy resources, such as rural remote areas or suburban application scenarios, and even in low-wind environments such as cities, to make full use of wind resources.

[0004] The patent with the publication number CN221762085U discloses a low-wind power generation device. Through the cooperation of an installation box, a support rod, a chute, a motor, a threaded rod, a moving block, a fixing plate, a torsion spring, a rotating rod, a windproof cloth, and a fixing rod, when the wind force is large, the motor is started. When the motor is in the working state, it will drive the threaded rod to rotate. The rotation of the threaded rod will drive the moving block to move. The movement of the moving block will drive the fixing rod to move. The movement of the fixing rod will drive the windproof cloth to move. At the same time, the reset of the torsion spring will drive the rotating rod to rotate, and the rotation of the rotating rod will wind up the windproof cloth. Through the above design, the windward area can be quickly reduced, avoiding the situation that the machine will be damaged when the wind force is large. However, the low-wind power generation technology of this device has the following problems:

[0005] ① The above invention does not consider that in actual applications, the power supply requirements of most power supply places cannot be interrupted. The existing low-wind power generation technology relies on intermittent charging times. For example, street lights are charged at night and discharged during the day. In this mode, low-wind power generation cannot ensure continuous, stable, and uninterrupted power supply. Especially in places where the power demand is continuous and cannot be interrupted, such as tunnels, it may cause potential safety hazards.

[0006] ②The fan blade design of the above-mentioned micro-wind power generation technology lacks a fixed rotation direction, resulting in random and uncontrollable wind directions. This not only increases the risk of fan damage but also reduces the effective utilization rate of wind resources.

[0007] ③The electric energy generated by the permanent magnet synchronous generator is alternating current, which limits its direct application to most electronic devices that require direct current or alternating current with a specific frequency. In addition, the insufficient stability of the power quality further restricts its applicable scenarios. Summary of the Invention

[0008] In order to overcome the deficiencies of the prior art, the present invention provides a micro-wind power generation device based on the highway tunnel scenario, which realizes the improvement of the utilization rate of micro-wind resources, so as to be able to stably supply power to electrical equipment continuously. By reasonably setting the control to charge and discharge the battery pack, the service life of the battery pack is increased.

[0009] In order to achieve the above-mentioned invention purpose, the present invention adopts the following technical solutions:

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention realizes stable uninterrupted power supply, which not only improves the service life of the battery pack, but also avoids the workload of manually switching the battery pack and monitoring and maintenance. The existing micro-wind power generation technology ignores the damage to the battery caused by simultaneous charging and discharging of the battery. The storage battery cannot make the load power consumption greater than 120% of the charging for a long time. Being in a state of being unable to be fully charged for a long time will greatly damage the battery. However, it is often difficult to control the power generation amount of micro-wind power generation, which leads to frequent battery replacement. The present invention solves the above problems of battery damage in the prior art by closing the relay switch K5 to start the electromagnetic brake when the power generation amount of the wind energy conversion and power generation device is excessive, controlling the wind energy conversion and power generation device to stop generating electricity until the power of any one battery in the battery pack is lower than 20% of the battery capacity, then disconnecting the relay switch K5 to stop the electromagnetic brake and closing the relay switch K6 to re-perform the cyclic charge and discharge of the battery pack.

[0019] Another significant advantage of the present invention is that the micro-wind power generation device is designed with full consideration of the special environment of highway tunnels. It has a compact structure and is easy to install, capable of easily adapting to the space limitations in the tunnel. Meanwhile, its durable shell material ensures the stable operation of the device under various harsh weather conditions.

[0020] In the present invention, the wind blades of the wind energy conversion and power generation device adopt horizontal spiral wind blades, which have a low starting wind speed and a single wind direction (constant rotation direction), reducing the damage rate and saving maintenance costs, thereby improving the utilization rate of micro-wind energy resources.

[0021] In addition, the design of the horizontal spiral wind blades also optimizes the aerodynamic performance, enabling it to efficiently convert wind energy into electrical energy even under micro-wind conditions. Compared with traditional vertical-axis or horizontal-axis wind blades, the horizontal spiral wind blades have a higher energy conversion efficiency in low-wind-speed environments, which is particularly crucial for the specific scenario of highway tunnels, as the wind speed in the tunnel is often relatively low and stable. At the same time, the design of this kind of wind blade also reduces the mechanical stress caused by wind direction changes, further extending the service life of the device.

[0022] In the battery pack control logic gate circuit of the present invention, the voltage sensors are respectively connected in parallel with two batteries. When it is detected that the voltage of the storage battery reaches the set voltage threshold value, the charging battery is immediately switched, enabling the two storage batteries to be alternately charged and discharged one by one, realizing continuous and uninterrupted power supply to the load and forming a complete charge-discharge control circuit.

[0023] The present invention can effectively solve the problem of discontinuous power supply in areas with low wind speed in tunnel scenarios, thereby providing continuous and stable power supply and increasing the safety of highway tunnels.

[0024] The output current of the wind energy conversion and power generation device of the present invention is rectified and regulated and then stored in the battery pack for power supply to electronic devices, and it is applicable to the vast majority of electronic devices.

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] The following describes the implementation manners of the present invention through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0034] A gentle wind power generation device based on the highway tunnel scenario includes a wind energy conversion and power generation device, a rectification module, a voltage stabilizing module, a battery pack charge and discharge control circuit, and a battery pack control logic gate circuit; the power output end of the wind energy conversion and power generation device is connected to the input end of the rectification module, the output end of the rectification module is connected to the input end of the voltage stabilizing module, the voltage stabilizing module is connected to the charge and discharge control circuit, and the battery pack control logic gate circuit is used to select the battery in the battery pack according to the battery power in the battery pack to supply power to the electrical equipment load. The wind energy is converted into electrical energy by the wind energy conversion and power generation device and transmitted to the rectification module. The rectification module rectifies the alternating current into direct current and transmits it to the voltage stabilizing module. The unstable direct current is voltage-stabilized by the voltage stabilizing module to output a stable voltage. The battery pack charge and discharge control circuit controls the charging and discharging of the battery pack according to the power generation amount of the wind energy conversion and power generation device, and controls the wind energy conversion and power generation device to stop generating electricity.

[0035] For example, in the case where the power generation amount of the wind energy conversion and power generation device is insufficient, the system will select a high-power battery to supply power to the electrical equipment, or charge the low-power battery; when the power generation amount is excessive, the system will control the wind energy conversion and power generation device to stop generating electricity to protect the generator from damage.

[0036] Such as Figure 1As shown in the figure, the wind energy conversion device into electrical energy includes a horizontal spiral blade, a generator, a blade fixing component, a fixing component capable of accommodating the generator, a fixed connection component, a support rod fixing component, a support rod component, and a base component. The generator is installed inside the fixing component capable of accommodating the generator. The generator is fixedly connected to the rear end of the horizontal spiral blade. The blade fixing component is movably connected to the front end of the horizontal spiral blade. One end of the fixed connection component is fixedly connected to the fixing component capable of accommodating the generator, and the other end of the fixed connection component is fixedly connected to the blade fixing component. The bottom end of the fixed connection component is fixedly connected to the support fixing rod component. The support fixing rod component is fixedly connected to one end of the support rod component, and the other end of the support rod component is fixedly connected to the base component. Optionally, the material of the horizontal spiral blade is made of fiberglass epoxy resin.

[0037] For example, the generator in the wind energy conversion device into electrical energy can adopt a direct-drive permanent magnet synchronous generator. Permanent magnets are installed inside the stator of the direct-drive permanent magnet synchronous generator to generate a stable magnetic field, which has the advantages of high effective power, fast response speed, and brushless design. Driven by the wind force, the stationary horizontal spiral blade starts to rotate. When the rotation speed approaches the ideal synchronous speed of the motor, it will drive the rotor of the disk generator to rotate together. Under the action of the magnetic field generated by the permanent magnets of the rotor, the three-phase windings of the stator rotate and cut the magnetic field relative to the rotor, thereby inducing an alternating electromotive force (i.e., alternating current). Due to the fluctuation of the rotation speed, the generated current is also unstable.

[0038] As shown in Figure 2, the battery pack charge and discharge control circuit includes a voltage sensor module, relay switches K1, K2, K3, K4, K5, K6, batteries B1, B2, and a wind speed sensor. The wind speed sensor is installed at the rear end of the horizontal spiral blade. The wind speed sensor is connected to one end of relay switch K6. The input end of the rectification module is connected to the other end of the electrical switch K6. The output end of the voltage stabilization module is respectively connected to electrical switch K1 and relay switch K2. Electrical switch K1 is connected to battery B1, and relay switch K2 is connected to battery B2. One end of relay switch K5 is connected to the wind energy conversion device into electrical energy. The other end of relay switch K5 is respectively connected to one end of relay switch K3, one end of relay switch K4, and the electrical equipment load. The voltage sensor module is respectively connected to the other end of relay switch K3 and the other end of relay switch K4.

[0039] It should be noted that the charge and discharge control circuit of this battery pack can ensure that the wind turbine stably supplies power to the electrical equipment load when the power generation is insufficient, and stores electrical energy in a timely manner when the power generation is excessive, so as to achieve continuous and stable power generation and power supply functions. For example, when the voltage of the battery is detected to reach the preset voltage threshold, it will immediately switch to the backup battery for charging, thus realizing the alternating charge and discharge of the two battery units. This strategy ensures the continuous supply of electrical energy and optimizes the charge and discharge efficiency of the battery. Generally, the charge and discharge efficiency of the battery is above 85%.

[0040] The electromagnet (consisting of an iron core and a coil) is installed on the stator of the generator, and the rotor is connected to the wind wheel via a rotating shaft. When braking is required, the control relay switch K6 is disconnected to cut off the power supply of the rotor and stop it from generating an induced electromotive force. At the same time, the relay switch K5 is closed to energize the electromagnet and generate a magnetic field. According to the principle of magnetism, the magnetic field will exert a force on the conductor (rotating shaft) on the rotor, thus generating an electromagnetic suction force. This electromagnetic suction force will interact with the frictional force on the rotor, causing the rotor to stop. When the power generation of the wind energy conversion device is excessive or the external wind speed exceeds the safe range, the electromagnetic brake is started by closing the relay switch K5 to decelerate the fan until it stops working (for example, once the wind speed sensor detects that the wind speed reaches the maximum safety limit of 45 m / s, the electromagnetic brake is started to protect the wind turbine from damage and decelerate it to the safe wind speed range before stopping power generation). When the power of battery B1 or battery B2 drops below 20% of its capacity, the electromagnetic brake is disconnected (i.e., the relay switch K5 is disconnected and the relay switch K6 is closed), and then the cyclic charge and discharge function of the battery is executed.

[0041] As Figure 3 shown, the voltage stabilization module circuit includes a resistor R1, a triode Q1, a zener diode D2, a capacitor C1, and a capacitor C2. The output terminals of the rectification module are respectively connected to the collector terminal of the triode Q1 and one end of the resistor R1. The base terminal of the triode Q1 is respectively connected to the other end of the resistor R1, the negative terminal of the zener diode D2, and one end of the capacitor C1. The emitter terminal of the triode Q1 is respectively connected to one end of the capacitor C2 and the storage battery. The other end of the capacitor C1, the other end of the capacitor C2, and the positive terminal of the zener diode D2 are grounded. It should be noted that when the alternating current generated by the fan is directly connected to the rectification device, the direct current after rectification is not stable enough and cannot be directly stored or used, otherwise it will damage the equipment. Therefore, a voltage stabilization module needs to be added to make its output a relatively stable current and voltage, and then the positive and negative poles of the voltage stabilization module are respectively connected in series with the storage battery. The two storage batteries (B1, B2) are in a parallel relationship.

[0042] As Figure 4As shown, X1, X2, Y1, and Y2 are digital signals (0 or 1) after the voltage sensor undergoes analog-to-digital conversion. Among them, X1 and X2 are the full charge signals of batteries B1 and B2 respectively, and Y1 and Y2 are the low charge signals of batteries B1 and B2 respectively. V is the digital signal of the wind speed sensor, and all are input signals; K1, K2, K3, K4, K5, and K6 are output signals respectively. The input signals convey the signals to the corresponding 6 relay switches in the circuit through the above combinational logic relationship, that is, each output signal corresponds to a relay switch.

[0043] The battery pack control logic gate circuit includes NOR gate U1, NOR gate U2, NAND gate U3, NOT gate U4, NAND gate U5, NAND gate U6, AND gate U7, OR gate U8, NOR gate U9, and NOT gate U10; the input terminals of NOR gate U1 are respectively connected to the full charge signal output terminal X1 of battery B1 and the low charge signal output terminal Y1 of battery B1, and the output terminal of NOR gate U1 is connected to relay switch K1; the input terminals of NOR gate U2 are respectively connected to the full charge signal output terminal X2 of battery B2 and the low charge signal output terminal Y2 of battery B2, and the output terminal of NOR gate U2 is connected to relay switch K2; NAND gate U3 receives the full charge signal X1 of battery B1 and the low charge signal Y2 of battery B2, and its output controls relay switch K3 and serves as the input of NOT gate U4. The input terminals of NAND gate U5 are respectively connected to the full charge signal output terminal X2 of battery B2 and the low charge signal output terminal Y1 of battery B1, the input terminals of NAND gate U6 are respectively connected to the output terminal of NOT gate U4 and the output terminal of NAND gate U5, and the output terminal of NAND gate U6 is connected to relay switch K4; the input terminals of AND gate U7 are respectively connected to the low charge signal output terminal Y1 of battery B1 and the low charge signal output terminal Y2 of battery B2, the input terminals of OR gate U8 are respectively connected to the full charge signal output terminal X1 of battery B1, the full charge signal output terminal X2 of battery B2, and the wind speed signal output terminal V, the input terminals of NOR gate U9 are respectively connected to the output terminal of AND gate U7 and the output terminal of OR gate U8, and the output terminal of NOR gate U9 is respectively connected to relay switch K6 and the input terminal of NOT gate U10; the output terminal of NOT gate U10 is connected to relay switch K5. The battery pack control logic gate circuit is connected to the two batteries through a parallel voltage sensor. Once it detects that the battery voltage reaches the set threshold value, it immediately switches the battery charging, enabling the two batteries to charge and discharge alternately, ensuring continuous power supply to the load, thus forming a complete charge and discharge control circuit.

[0044] Further, it is set that when the voltage sensor detects that the battery power ≥ 90% of the capacity, the digital signal output is 1, and when the voltage sensor module detects that the battery power ≤ 20% of the capacity, the digital signal output is 0; when the battery B1 has insufficient power (≤ 20%), the relay switch K3 = 0, the relay switch K4 = 1, then the relay switch K1 = 1, the relay switch K2 = 0. When the battery B1 has sufficient power (≥ 90%) and the battery B2 power ≤ 20% of the capacity, the relay switch K3 = 1, the relay switch K4 = 0; then the relay switch K1 = 0, the relay switch K2 = 1. Similarly, the same applies to the battery B2.

[0045] Applied to the actual situation in the circuit structure: When it is detected that the battery B1 has insufficient power, the circuit is automatically switched to the discharge loop 2 in real time, and the battery B2 continuously supplies power to the electrical equipment. At the same time, due to the logic relationship of the gate circuit, the relay switch K2 will immediately disconnect and will not charge, while the relay switch K1 will close to charge B1. The same applies to the battery B2. The power states of the two batteries are monitored in real time. Once the preset trigger conditions are reached, the control function of the logic circuit is activated to achieve cyclic alternate power supply, ensuring continuous and uninterrupted power supply.

[0046] Those skilled in the art can clearly understand that for the convenience and brevity of description, the specific working processes of the systems and units described above can refer to the corresponding processes in the foregoing method embodiments and will not be elaborated herein.

[0047] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
