Description

Technical Field

[0001] This invention relates to the field of new energy power supply system technology, specifically a wind-solar hybrid power supply device. Background Technology

[0002] Wind-solar hybrid power supply systems belong to the field of new energy and renewable energy. They are power supply systems that comprehensively utilize both wind and solar energy, two clean energy sources. Wind-solar hybrid power supply systems are also commonly used in the marine sector, where many marine facilities are geographically dispersed, such as lighthouses, navigation lights, marine monitoring buoys, and marine observation stations. These facilities are often far from the terrestrial power grid and difficult to power through traditional transmission methods. Wind-solar hybrid power supply systems can generate electricity locally and independently power these dispersed facilities without the need for long-distance transmission lines, significantly reducing power supply costs and construction difficulties. For example, patent application number CN202210546... Invention patent 373.3 discloses a wind-solar hybrid intelligent street light. This solution includes a light pole, on which a light body and a wind turbine are mounted. A support plate is fixed to the light pole, and an adjustment frame is mounted on the support plate. A solar panel is mounted on the adjustment frame. The adjustment frame can change the angle of the solar panel and form a buffer when the wind force on the solar panel reaches a threshold, thereby reducing the impact of wind on the solar panel and improving the wind resistance of the solar panel. Another example is invention patent CN202410968627.X, which discloses a micro-off-grid wind-solar hybrid power supply system and device. The solution includes a base, on the top left side of which a wind turbine body is mounted, with blades connected to the top front side of the wind turbine body. A mounting plate is mounted on the top right side of the base, and a solar photovoltaic panel is connected to the top of the mounting plate via a shaft. An adjustment assembly is positioned between the driven gear ring and the inner wall of the top of the wind turbine body. A centrifugal drive assembly is located on the outside right side of the rotating shaft. A protection assembly is located on top of the solar photovoltaic panel. This micro-off-grid wind-solar hybrid power supply system and device can disconnect and reconnect the wind turbine generator based on the battery's charge level during operation. Controlling the transmission and interruption of power from wind turbines can prevent damage to the turbines and batteries, and can also automatically protect solar photovoltaic panels from damage during strong winds. However, current technology can only provide some protection for solar panels and cannot effectively protect the wind turbines. When facing severe weather such as strong typhoons and heavy rain, the enormous wind force of strong typhoons may cause the wind turbine blades to bear loads exceeding their design limits, resulting in damage such as cracks and breaks. At the same time, under the influence of typhoons, the tower may also tilt or even collapse due to excessive bending moments and torques, causing serious damage to the entire wind turbine. Summary of the Invention

[0003] The purpose of this invention is to provide a wind-solar hybrid power supply device to solve the problem that when facing severe weather such as strong typhoons and rainstorms, the huge wind force of strong typhoons may cause the wind turbine blades to bear loads exceeding the design limits, resulting in damage such as cracks and breaks in the blades. At the same time, under the action of strong winds, the tower may also tilt or even collapse due to excessive bending moment and torque, causing serious damage to the entire wind turbine.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A wind-solar hybrid power supply device includes a housing, a solar panel, a wind turbine, and an energy storage battery. The solar panel is mounted on the upper surface of the housing, and the energy storage battery is installed inside the housing. The wind turbine includes a generator body, a gearbox, a shaft, and an impeller. The generator body and gearbox are both installed inside the housing and connected to each other. The shaft is rotatably connected to the upper surface of the housing, and its lower end extends into the housing and connects to the gearbox. The shaft has multiple helical grooves circumferentially formed. The impeller is coaxially rotatably connected to the shaft and consists of two semi-cylindrical blades and a bushing. The two blades are symmetrically mounted on both sides of the bushing in an S-shape. The bushing also has a number of sliders corresponding to the helical grooves, and the sliders are slidably connected to the helical grooves. A support spring is fitted on the shaft, and the upper and lower ends of the support spring are respectively connected to the lower surface of the impeller and the upper surface of the housing. The connection includes a protective component on the rotating shaft. When the multiple sliders slide to the lower stop point of the spiral groove, the protective component is triggered, disengaging the bushing from the rotating shaft. The rotating shaft is equipped with a position sensor, a speed sensor, and an electromagnetic brake. The position sensor and speed sensor are electrically connected to the electromagnetic brake. When the speed sensor detects that the rotating shaft exceeds a set value, it triggers the electromagnetic brake to brake the rotating shaft. When the bushing moves to the upper stop point, it triggers the position sensor and releases the electromagnetic brake from braking the rotating shaft. This avoids the problem that the wind-solar hybrid power supply device may be subjected to loads exceeding the design limits by the huge wind force of strong typhoons and heavy rain, leading to damage such as cracks and breaks in the blades. At the same time, under the action of typhoons, the tower may also tilt or even collapse due to excessive bending moment and torque, causing serious damage to the entire wind turbine. This ensures the safety and stability of the wind-solar hybrid power supply device.

[0006] Preferably, an annular groove is formed on the outer wall of the rotating shaft. The annular groove is coaxial with the rotating shaft and is located at the lower end of multiple spiral grooves. The annular groove is connected to the lower end of the multiple spiral grooves. When the impeller is affected by strong winds and moves to the lower end of the spiral groove, the slider is embedded in the annular groove. At this time, the impeller will be disengaged from the control of the rotating shaft. This avoids the problem that the wind-solar hybrid power supply device will wear out due to the continuous rotation of the impeller by the huge wind force of the strong typhoon when facing severe weather such as strong typhoons and rainstorms. This ensures the reliability and stability of the wind-solar hybrid power supply device.

[0007] Preferably, a recycling trough is provided at the mounting point of the solar panel and the housing. The recycling trough is perpendicular to the rotating shaft, and a recycling sleeve is fitted on the rotating shaft. The support spring includes a first support section and a second support section. The recycling sleeve is installed between the first support section and the second support section. One end of the solar panel is slidably connected in the recycling trough, and the other end is rotatably connected to the recycling sleeve. When the support spring is driven by the impeller to contract, the recycling sleeve moves towards the housing. When the recycling sleeve moves towards the housing, it pushes multiple solar panels to fold towards the housing. This avoids the problem that the strong wind generated by strong typhoons and heavy rain can easily cause the surface of the solar panel to be hit by debris, or cause the solar panel to deform or crack due to excessive wind force, resulting in short circuits in the internal circuit. This ensures the reliability and stability of the wind-solar hybrid power supply device.

[0008] Preferably, scrapers are slidably connected to the lower sidewalls of the plurality of recycling tanks, and springs are installed on the scrapers. The springs are respectively installed on the plurality of solar panels. The springs push the scrapers to stick to the lower sidewalls of the recycling tanks, which avoids the problem of debris accumulating in the recycling tanks when the solar panels slide on the tanks, causing the solar panels to get stuck and the impeller to be unable to retract in time. This ensures the reliability and stability of the wind-solar hybrid power supply device.

[0009] Preferably, reinforcing plates are installed at the upper and lower ends of the two blades. Multiple reinforcing plates are inclined with the cross-section of the two blades and are inclined downward along the opening direction of the two blades. The reinforcing plates can enable the blades to maintain good structural integrity and shape under severe weather conditions, ensuring the smooth rotation of the wind turbine rotor and thus ensuring the stability of the power generation process. This avoids the problem of sudden fluctuations or interruptions in power generation caused by blade problems. At the same time, the reinforcing plates can also reduce the loss of wind power passing over the blades and increase the rotational force of the rotor. The inclined setting of the reinforcing plates can also prevent the accumulation of snow and rainwater from causing the rotor rotational resistance. It is worth noting that under the action of wind, the inclined setting of the reinforcing plates can also provide downforce to the blades, preventing the blades from repeatedly detaching from the annular groove in strong wind conditions.

[0010] Preferably, a buffer block is installed on the upper end face of the rotating shaft, and a buffer groove is coaxially formed on the lower end face of the buffer block. The inner and outer rings of the buffer groove are equal to the inner and outer rings of the bushing, respectively. A pressure relief port is formed on the upper end face of the buffer block, and the lower end of the pressure relief port is connected to the buffer groove. This avoids the problem that when the impeller is driven to contract by a large wind force and then changes to a small wind force, the contracted impeller is driven by the spring force to move rapidly to the upper end of the rotating shaft, causing the slider to collide with the upper end of the spiral groove, which would lead to damage to the slider and the spiral groove. This ensures the reliability and stability of the wind-solar hybrid power supply device.

[0011] Preferably, a bellows is also sleeved outside the support spring. The bellows is divided into upper and lower sections. The upper section of the bellows is connected to the shaft sleeve and the recovery sleeve, respectively, and the lower section of the bellows is connected to the shaft sleeve and the housing, respectively. This prevents foreign objects from entering the spiral groove and causing jamming when the impeller slides down. At the same time, it prevents the shaft from coming into contact with the high salinity of the external air, which would cause corrosion on the surface of the shaft and affect its appearance and surface quality. This ensures the reliability and stability of the wind-solar hybrid power supply device.

[0012] Preferably, a first fixing groove is formed on the upper end face of the rotating shaft, and the buffer block is threadedly connected to the first fixing groove. The thread direction in the first fixing groove is opposite to the rotation direction of the impeller. The lower end circumference of the bushing is evenly distributed with second fixing grooves corresponding to the number of sliders. The extended central axes of the multiple second fixing grooves are perpendicularly intersecting the central axis of the rotating shaft. The multiple sliders are threadedly connected to the multiple second fixing grooves respectively. This avoids the problem of long-term shutdown of the power supply device due to long-term maintenance after impeller damage, which affects the power supply. It ensures the maintainability and adaptability of the wind-solar hybrid power supply device.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This invention features multiple spiral grooves circumferentially formed on the rotating shaft, with corresponding number of sliders installed on the bushing, and a support spring fitted on the rotating shaft. This design prevents the wind turbine blades from being subjected to loads exceeding design limits due to the immense wind force of strong typhoons, which could lead to cracks, breakage, or other damage. Additionally, under typhoon conditions, the tower may tilt or even collapse due to excessive bending and torque, causing damage to the wind turbine. This invention ensures the safety and stability of the wind-solar hybrid power supply device.

[0015] 2. This invention provides an annular groove on the outer wall of the rotating shaft, which is coaxial with the rotating shaft and located at the lower end of multiple spiral grooves. The annular groove is connected to the lower end of the multiple spiral grooves. This avoids the problem of the wind-solar hybrid power supply device experiencing excessive wear due to the continuous rotation of the impeller caused by the strong wind force of a strong typhoon or heavy rain. This ensures the reliability and stability of the wind-solar hybrid power supply device.

[0016] 3. This invention features a recycling trough at the solar panel and housing mounting point, with a recycling sleeve fitted on the rotating shaft. One end of the solar panel is slidably connected to the recycling trough, and the other end is rotatably connected to the recycling sleeve. This avoids the problems caused by strong winds during severe weather such as typhoons and heavy rain, which can easily cause the solar panel surface to be struck by debris or deformed and cracked due to excessive wind force, resulting in short circuits in the internal circuitry. This ensures the reliability and stability of the wind-solar hybrid power supply device. Attached Figure Description

[0024] Please see Figures 1 to 6 This invention provides a wind-solar hybrid power supply device, the technical solution of which is as follows:

[0025] A wind-solar hybrid power supply device includes a housing 1, a solar panel 2, a wind turbine 3, and an energy storage battery 4. The solar panel 2 is mounted on the upper surface of the housing 1, and the energy storage battery 4 is mounted inside the housing 1. The wind turbine 3 includes a generator body 301, a gearbox 302, a shaft 303, and an impeller 304. The generator body 301 and the gearbox 302 are both mounted inside the housing 1 and connected to the gearbox 302. The shaft 303 is rotatably connected to the upper surface of the housing 1, and its lower end extends into the housing 1 and connects to the gearbox 302. The shaft 303 has multiple spiral grooves 305 circumferentially formed on its circumference, and an annular groove 306 is also formed on the outer wall of the shaft 303. The shaft 303 is coaxial, and the annular groove 306 is located at the lower end of multiple spiral grooves 305, and the annular groove 306 is connected to the lower end of the multiple spiral grooves 305. The impeller 304 is coaxially rotatably connected to the shaft 303. The impeller 304 consists of two semi-cylindrical blades 3041 and a bushing 3042. The two blades 3041 are symmetrically installed on both sides of the bushing 3042 in an S-shape. Reinforcing plates 603 are installed at the upper and lower ends of the two blades 3041. The multiple reinforcing plates 603 are inclined with the cross-section of the two blades 3041, and the multiple reinforcing plates 603 are inclined downward along the opening direction of the two blades 3041. The bushing 3042 is also equipped with a number of sliders 307 corresponding to the spiral grooves 305. The multiple sliders 307 are slidably connected in the multiple spiral grooves 305 respectively. A support spring 5 is fitted onto the rotating shaft 303. The upper and lower ends of the support spring 5 are connected to the lower end face of the impeller 304 and the upper end face of the housing 1, respectively. A sliding washer made of polytetrafluoroethylene is installed at the connection point between the support spring 5 and the lower end face of the impeller 304 and the upper end face of the housing 1. A bellows 8 is also fitted over the support spring 5. The bellows 8 is divided into upper and lower sections. The upper section of the bellows 8 is connected to the shaft sleeve 3042 and the recovery sleeve 602, respectively. The lower section of the bellows 8 is connected to the shaft sleeve 3042 and the housing 1, respectively. A buffer block 701 is installed on the upper end face of the rotating shaft 303. A buffer groove 702 is coaxially formed on the lower end face of the buffer block 701. The inner and outer rings of the buffer groove 702 are equal to the inner and outer rings of the shaft sleeve 3042, respectively. A pressure relief port 703 is provided on the end face, and the lower end of the pressure relief port 703 is connected to the buffer groove 702. A first fixing groove 901 is provided on the upper end face of the rotating shaft 303. The buffer block 701 is threadedly connected to the first fixing groove 901. The thread direction in the first fixing groove 901 is opposite to the rotation direction of the impeller 304. The lower end of the bushing 3042 is evenly distributed with second fixing grooves 902, corresponding to the number of sliders 307. The extended central axes of the multiple second fixing grooves 902 are perpendicularly intersecting the central axis of the rotating shaft 303. Multiple sliders 307 are threadedly connected to the multiple second fixing grooves 902. A recycling groove 601 is provided at the mounting position of the solar panel 2 and the housing 1. The recycling groove 601 is perpendicular to the rotating shaft 303. A recycling sleeve 602 is fitted on the rotating shaft 303.The support spring 5 includes a first support section 501 and a second support section 502. A recycling sleeve 602 is installed between the first and second support sections 501 and 502. One end of the solar panel 2 is slidably connected to the recycling trough 601, and the other end is rotatably connected to the recycling sleeve 602. Scrapers 604 are slidably connected to the lower sidewalls of multiple recycling troughs 601. Each scraper 604 is equipped with a spring 605, which is correspondingly installed on multiple solar panels 2. The springs 605 push the scrapers 604 to adhere to the lower sidewalls of the recycling troughs 601. A protective component is provided on the rotating shaft 303. When multiple sliders 307 slide to the lower stop point of the spiral groove 305, the protective component is triggered, disengaging the bushing 3042 from the rotating shaft 303. A position sensor, a speed sensor, and an electromagnetic sensor are provided on the rotating shaft 303. The brake, position sensor, and speed sensor are all electrically connected to the electromagnetic brake. When the speed sensor detects that the shaft 303 exceeds a set value, it triggers the electromagnetic brake to brake the shaft 303. When the bushing 3042 moves to the top dead center, it triggers the position sensor and releases the electromagnetic brake from the shaft 303. This prevents the wind-solar hybrid power supply unit from being damaged in severe weather conditions such as strong typhoons and heavy rain. In such cases, the immense wind force of a strong typhoon could cause the blades 3041 of the wind turbine 3 to bear loads exceeding their design limits, leading to cracks or breakage. Furthermore, under the influence of a typhoon, the tower may tilt or even collapse due to excessive bending and torque, causing serious damage to the entire wind turbine 3. This ensures the safety and stability of the wind-solar hybrid power supply unit.

[0026] When working, please refer to Figures 1 to 6In the wind-solar hybrid power supply unit, the support spring 5 applies elastic force to the housing 1 and the bushing 3042, preventing the bushing 3042 from sliding down along the spiral groove 305 under normal conditions. When the wind-solar hybrid power supply unit faces strong typhoon weather, the strong wind will drive the impeller 304 to rotate rapidly. At the same time, the rotational force of the bushing 3042 will also be applied to the rotating shaft 303 through the slider 307. At this time, due to the existence of the spiral groove 305, the slider 307 will have a tendency to slide downward. Under normal power generation conditions, the downward sliding tendency of the slider 307 will be counteracted by the support spring 5. At this time, the rotational force of the impeller 304 will be applied to the rotating shaft 303, driving the rotating shaft 303 to rotate. The rotating shaft 303 drives the gearbox 302 and the wind turbine 3 to rotate. When the wind force continues to increase, the rotational force of the impeller 304 will be applied to the slider 304 to rotate downward. The guide of 307 and the spiral groove 305 is applied to the support spring 5 and compresses the support spring 5. At this time, the slider 307 is guided by the spiral groove 305 and rotates downward spirally towards the housing 1. At the same time, when the support spring 5 contracts, the bellows 8 will also contract. At this time, the recovery sleeve 602 will also be pushed by the pressure of the support spring 5, causing the recovery sleeve 602 to move towards the housing 1. When the recovery sleeve 602 moves towards the housing 1, it pushes multiple solar panels 2 to fold towards the housing 1. At this time, since the distance between the impeller 304 and the housing 1 is constantly shortening, the torque on the connection between the shaft 303 and the housing 1 is also constantly decreasing. When the impeller 304 slides to the lower end of the spiral groove 305, the slider 307 will be embedded in the annular groove 306. At this time, the impeller 304 will be disengaged from the control of the shaft 303.

[0027] Furthermore, when the wind force on the impeller 304 decreases, the support spring 5 will push the sliding sleeve to drive the slider 307 to disengage from the annular groove 306 and move away from the housing 1 through the spiral groove 305. At this time, the stretched support spring 5 will drive the recovery sleeve 602 to move away from the housing 1. The recovery sleeve 602 will drive multiple solar panels 2 to unfold. During the stretching of the support spring 5, the bushing 3042 will be pushed by the support spring 5 to move quickly away from the housing 1. When the slider 307 is about to contact the upper end of the spiral groove 305, the bushing 3042 will be embedded in the buffer groove 702. At this time, the air in the buffer groove 702 will be compressed and will buffer the bushing 3042. At the same time, the pressure relief port 703 on the upper end of the buffer block 701 can balance the air pressure in the buffer groove 702 and avoid damage to the device caused by the additional resistance or pressure generated by air compression. At this time, the impeller 304 will slowly move to the upper end of the rotating shaft 303 through the exhaust speed of the pressure relief port 703 and return to the normal operating state of the wind-solar hybrid power supply device.

[0028] It is worth noting that when the speed sensor detects that the rotating shaft 303 exceeds the set value, it triggers the electromagnetic brake to brake the rotating shaft 303. When the bushing 3042 moves to the top dead center, it triggers the position sensor and releases the electromagnetic brake from braking the rotating shaft 303.

[0029] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
