Currently, non-powered wind turbines are widely used on land, but due to the low power generation efficiency of these resistance-type wind turbines, their application on offshore platforms is limited. However, given the environmental factors at sea, the value of wind energy cannot be ignored. Summary of the Invention

The device can be installed on offshore marine platforms to achieve power generation efficiency close to that of lift-type wind turbines, and power equipment on offshore platforms such as solar navigation lights. The device has a simple structure and low cost.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is:

[0005] A non-powered wind turbine power generation and energy storage device suitable for offshore platforms comprises a base and a non-powered wind hood arranged at the top of the base and rotatably connected to the base; a connecting shaft is provided in the middle portion of the inner cavity of the non-powered wind hood, the connecting shaft is fixedly connected to the non-powered wind hood and rotates synchronously, a vertical generator is provided on the upper portion of the connecting shaft and a disc generator is provided on the lower portion, and the two generators are driven to generate electricity through the rotation of the connecting shaft; a battery and a voltage stabilizer are provided in the inner cavity of the base, the vertical generator and the disc generator are respectively connected to the voltage stabilizer, and output current after voltage stabilization by the voltage stabilizer to directly power equipment on the platform; the battery is connected to the voltage stabilizer to store excess electrical energy in the battery.

[0006] In the above solution, a protective sleeve is provided on the outer side of the connecting shaft located on the vertical generator, and a waterproof plate is provided on the bottom of the protective sleeve.

[0007] In the above solution, the side wall of the non-powered hood is provided with a plurality of guide grooves distributed in a circumferential array for draining rainwater and condensed water generated during the operation of the device; the guide grooves are located on the upper part of the waterproof plate.

[0008] In the above solution, ferromagnetic material is provided between the bottom of the waterproof plate and the disk generator to enhance the magnetic field of the disk generator.

[0009] In the above scheme, an encoder is provided at the bottom of the disk generator, and a controller is also provided in the inner cavity of the base. The encoder is connected to the controller signal to transmit the measured connecting shaft speed signal to the controller. The controller controls the connecting shaft speed according to the connecting shaft speed signal to achieve maximum power generation efficiency.

[0010] In the above solution, the upper portion of the connecting shaft is fixedly connected to the middle sleeve of the vertical generator, and the lower portion of the connecting shaft is fixedly connected to the upper end plate of the disk generator; the upper and lower ends of the connecting shaft are supported by lubrication-free bearings.

[0014] In the above solution, the base includes a cylindrical body and a flange installed at the bottom end of the cylindrical body, and a plurality of reinforcing plates distributed in a circumferential array are provided between the flange and the cylindrical body.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention utilizes sustainable wind energy in the marine environment to design a non-powered wind turbine power generation and energy storage device. By combining a vertical generator and a disc generator, dual energy supply and power generation are achieved, which improves energy supply efficiency and achieves power generation efficiency close to that of a lift-type wind turbine. At the same time, the structure is relatively simple and the cost is low. A voltage stabilizer is installed at the bottom. Since the output power of the resistance-type wind turbine is extremely unstable, when the input voltage or load changes, the voltage stabilizer can maintain the stability of the output voltage, thereby preventing the generator output voltage from being too high and causing impact on the battery and subsequent loads. Excess electrical energy is stored in the battery, ensuring the supply of electricity under special sea conditions.

[0017] 2. An encoder is set at the bottom of the disc generator to monitor the speed of the connecting shaft. Since the wind turbine adopts the principle of vertical axis resistance wind turbine power generation, its speed is the highest at a specific wind speed. The encoder can monitor the speed of the connecting shaft to maximize the utilization of wind energy.

[0018] 3. A specific ferromagnetic material is installed on the top of the disk generator. The paramagnetic ferromagnetic material is placed above the permanent magnet. At normal temperature, the ferromagnetic material exhibits magnetism under the action of an external magnetic field, and the direction of the magnetization intensity is the same as the magnetic field intensity. It will generate an additional magnetic field with the same direction as the external magnetic field, which is beneficial to improve the magnetic field of the disk generator and increase the power generation efficiency.

[0019] 4. The design of waterproof plate and guide groove can drain rainwater and condensation water in time to prevent them from seeping into the lower structure, thus improving the safety of electrical components inside the fan.

[0020] 5. The device of the present invention can be used to power equipment on offshore platforms. For example, in navigation lights, utilizing the sustainable dual energy of wind and solar energy in the marine environment, this solves the problems of traditional navigation lights' endurance and the significant limitations of new solar-powered navigation lights. This further improves the lights' endurance and reliability while saving energy, thus possessing significant strategic significance. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0027] like Figure 1-3As shown, an embodiment of the present invention provides an unpowered wind turbine power generation and energy storage device suitable for offshore platforms, comprising a base 3 and an unpowered wind hood 5 arranged at the top of the base 3 and rotatably connected to the base 3; a connecting shaft 15 is provided in the middle part of the inner cavity of the unpowered wind hood 5, and the connecting shaft 15 is fixedly connected to the unpowered wind hood 5 and rotates synchronously, and a vertical generator 6 is provided on the upper part of the connecting shaft 15 and a disk generator 11 is provided on the lower part. The sea breeze blows the blades of the unpowered wind hood 5 to drive the connecting shaft 15 to rotate, converting the kinetic energy of the wind into the mechanical energy of the connecting shaft 15; at the same time, the connecting shaft 15 drives the vertical generator 6 and the disk generator 11 to cut the magnetic flux lines and rotate, thereby further converting the mechanical energy into electrical energy. By combining the vertical generator 6 and the disk generator 11, dual energy supply and power generation are achieved, thereby improving the energy supply efficiency. A battery 2 and a voltage stabilizer 1 are provided in the inner cavity of the base 3. The vertical generator 6 and the disc generator 11 are respectively connected to the voltage stabilizer 1. After being stabilized by the voltage stabilizer 1, the output current directly supplies power to the equipment on the platform; the battery 2 is connected to the voltage stabilizer 1 to store excess electrical energy in the battery 2.

[0028] As a further optimization, in this embodiment, a protective sleeve 16 is provided on the connecting shaft 15, located outside the vertical generator 6. A waterproof plate 10 is installed at the bottom of the protective sleeve 16 to prevent rainwater and condensation generated during operation from entering the lower structure, thereby ensuring the safety and reliability of the device during operation. A plurality of reinforcing ribs 9 are arranged in a circumferential array between the waterproof plate 10 and the protective sleeve 16, ensuring the safety and reliability of the device. The sidewalls of the unpowered hood 5 are provided with a plurality of guide grooves 14 arranged in a circumferential array. These guide grooves 14 are located above the waterproof plate 10 and are used to drain rainwater and condensation, improving the safety of the wind turbine's internal electrical components.

[0029] As a further optimization, in this embodiment, ferromagnetic material 4 is disposed between the bottom of waterproof plate 10 and disk generator 11. At normal temperatures, ferromagnetic material 4 exhibits magnetism under the influence of an external magnetic field. Due to the paramagnetic nature of ferromagnetic material 4, the direction of its magnetization intensity is the same as the magnetic field intensity, and it generates an additional magnetic field in the same direction as the external magnetic field, which helps to enhance the total magnetic field and thus improve the power generation efficiency of disk generator 11. Specifically, ferromagnetic material 4 is installed at the bottom of waterproof plate 10.

[0030] Further optimization, in this embodiment, an encoder 12 is provided at the bottom of the disc generator 11 for monitoring the rotational speed of the connecting shaft 15. Since the wind turbine adopts the principle of vertical axis resistance wind turbine power generation, its rotational speed has the maximum wind energy utilization rate at a specific wind speed. The encoder 12 can monitor the rotational speed of the connecting shaft 15 to maximize the wind energy utilization rate. The inner cavity of the base 3 is also provided with a controller. The encoder 12 is connected to the controller signal and transmits the measured rotational speed signal of the connecting shaft 15 to the controller. The controller controls the rotational speed of the connecting shaft 15 according to the rotational speed signal of the connecting shaft 15 to achieve maximum power generation efficiency. In actual application, when the rotational speed of the connecting shaft 15 is greater than the preset value (i.e., the specific wind speed at the maximum power mentioned above), the controller controls the rotational speed of the connecting shaft 15 according to the data monitored by the encoder 12.

[0031] The encoder 12 and voltage stabilizer 1 work together to prevent excessively high generator output voltage from impacting the battery 2 and subsequent loads. The encoder 12 and voltage stabilizer 1 stabilize both voltage and speed, improving the wind turbine's power generation efficiency while also ensuring safety and stability during operation.

[0032] Further optimizing this embodiment, the upper portion of connecting shaft 15 is fixedly connected to the central sleeve of vertical generator 6, while the lower portion of connecting shaft 15 is fixedly connected to the upper end plate of disk generator 11. The upper and lower ends of connecting shaft 15 are supported by lubrication-free bearings. It should be noted that vertical generator 6 and disk generator 11 can utilize existing models, and their internal structures are not described in detail here. Because connecting shaft 15 drives the generator, compared to other similar devices, there is no complex gear structure, eliminating the concern of increased friction due to rusting gears in marine environments. Furthermore, the use of special lubrication-free bearings eliminates the need for routine maintenance, significantly reducing maintenance workload and improving device stability.

[0033] For further optimization, in this embodiment, a solar navigation light 7 is provided on the top of the unpowered wind hood 5, and the solar navigation light 7 is connected to the voltage stabilizer 1 and is powered by the unpowered wind turbine power generation and energy storage device of the present invention.

[0034] Further optimization, in this embodiment, a lightning rod 8 is provided on the top of the solar navigation light 7 to ensure the stability of the device in working under the harsh environment of the ocean.

[0035] Further optimization, in this embodiment, the permanent magnet of the disk generator 11 is made of neodymium iron boron material, which has high magnetic properties and easy processing. Compared with common ferrite magnetic materials, the magnetic energy product of neodymium iron boron material can reach 50MGOe, which is 10 times that of ferrite material, which is beneficial to increasing power generation efficiency.

[0036] Further optimized, in this embodiment, the base 3 includes a cylindrical body and a flange installed at the bottom end of the cylindrical body, and a plurality of reinforcing plates 13 distributed in a circular array are provided between the flange and the cylindrical body.

[0037] Further optimized, in this embodiment, the base 3 is made of 316L stainless steel and is painted as a whole, ensuring the corrosion resistance and strength of the device.

[0038] The operating principle of the non-powered wind turbine power generation and energy storage device suitable for offshore platforms is as follows: The non-powered wind turbine power generation and energy storage device is installed on the offshore platform. The sea breeze blows the blades of the non-powered wind cap 5, driving the connecting shaft 15 to rotate, driving the vertical generator 6 and the disk generator 11 to cut through the magnetic flux lines. The rotation of the wind turbine generates mechanical energy, which is further converted into electrical energy. During operation, an encoder 12 monitors the speed of the connecting shaft 15 in real time. If the main shaft speed exceeds a preset value, the controller controls the speed of the connecting shaft 15 based on the data monitored by encoder 12, thereby achieving maximum power generation efficiency. Simultaneously, during operation, the voltage regulator 1 controls the output voltage within a certain range, thereby preventing excessive generator output voltage from impacting the battery 2 and subsequent loads. During operation of the navigation light of this embodiment, solar and wind energy are combined to initially power the navigation light. Excess electricity is then fed into the battery 2 and then further into the platform power grid.

[0039] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are protected by the present invention.
