[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Embodiment 1 As Figure 1-6 described, a power supply device for a floating offshore wind power monitoring system provided by the present invention includes a triangular base 1, a wind power device 2, and three solar photovoltaic panels 3.

A multi-directional driving device 5 is installed at the center of the top of the triangular base 1. Three descaling devices 4 are installed at the top of the triangular base 1. The solar photovoltaic panels 3 are located below the descaling devices 4. A flushing device 6 is installed at the bottom of the triangular base 1, and the flushing device 6 extends above the solar photovoltaic panels 3.

[0027] The flushing device 6 includes three water boxes 61.

[0028] The descaling device 4 includes a protective box 41. The protective box 41 is fixedly connected to the top of the triangular base 1. Two threaded rods 42 penetrate through one side of the protective box 41 close to the solar photovoltaic panel 3, and the protective box 41 and the threaded rods 42 are movably connected through bearings. One end of the threaded rod 42 extending into the protective box 41 is fixedly connected to a first sprocket 43. The two first sprockets 43 are connected to each other through a chain 44.

A threaded sleeve 46 is sleeved on the outer end of the threaded rod 42, and the threaded sleeve 46 and the threaded rod 42 are connected by threads. The water box 61 is fixedly connected between the two threaded sleeves 46. A scraping strip 47 is fixedly connected to the bottom of the water box 61. The scraping strip 47 is located above the solar photovoltaic panel 3, and the bottom of the scraping strip 47 is in contact with the top of the solar photovoltaic panel 3.

[0029] The flushing device 6 further includes a water pump 64, the water pump 64 is fixedly connected to the bottom of the triangular base 1, the water inlet of the water pump 64 is connected with a suction pipe 65 through a flange, the water outlet of the water pump 64 is connected with a connecting pipe 66 through a flange, the end of the connecting pipe 66 is connected with three hoses 63 through a tee joint, and the ends of the three hoses 63 are respectively fixedly connected to three water boxes 61, and a plurality of spray nozzles 62 are fixedly connected to one side of the water box 61.

[0030] The flushing device 6 is used in cooperation with the descaling device 4. While locally taking seawater to flush the solar photovoltaic panel 3, the scraping strip 47 in the descaling device 4 scrapes off the seawater scale and sundries such as bird droppings on the solar photovoltaic panel 3. When the solar photovoltaic panel 3 is flushed with seawater, some scale and sundries such as bird droppings can also be humidified and softened, making it easier to scrape off.

[0031] Two fixing seats 67 are sleeved on the outer end of the connecting pipe 66, and the connecting pipe 66 is fixedly connected to the bottom of the triangular base 1 through the fixing seats 67. The fixing seats 67 can fix the position of the connecting pipe 66, avoiding the problem that the connection between the connecting pipe 66 and the water outlet of the water pump 64 is broken due to the random shaking of the connecting pipe 66.

[0032] The multi-directional driving device 5 includes a waterproof cover 51, the waterproof cover 51 is fixedly connected to the center of the top of the triangular base 1, an installation plate 52 is fixedly connected inside the waterproof cover 51, a reduction motor 53 is fixedly connected to the top of the installation plate 52, a first bevel gear 54 is fixedly connected to the output shaft of the reduction motor 53, three transmission rods 55 penetrate through the outer end of the waterproof cover 51, and a second bevel gear 56 is fixedly connected to one end of the transmission rod 55 located inside the waterproof cover 51. The three second bevel gears 56 are respectively meshed and connected with the first bevel gear 54. The multi-directional driving device 5 can drive the three transmission rods 55 to rotate simultaneously by one reduction motor 53, and then drive the three descaling devices to operate synchronously through the three transmission rods 55.

[0033] The end of the transmission rod 55 penetrates through the protective box 41 and extends into the protective box 41, and the protective box 41 and the transmission rod 55 are movably connected through a bearing. One end of the transmission rod 55 extending into the protective box 41 is fixedly connected with a second sprocket 57. The second sprocket 57 is located between the two first sprockets 43, and the second sprocket 57 and the two first sprockets 43 are connected with each other through a chain 44. The second sprocket 57 is driven by the two first sprockets 43 through the chain 44. Compared with the problem of belt drive slipping, the transmission efficiency is higher.

[0034] An additional thickening block 58 is integrally formed at the connection between the outer side of the waterproof cover 51 and the transmission rod 55. The transmission rod 55 passes through the thickening block 58, and the transmission rod 55 is movably connected to the thickening block 58. The first bevel gear 54, the transmission rod 55, the second bevel gear 56, and the thickening block 58 are all located below the mounting plate 52. The thickening block 58 can improve the stability of the connection between the transmission rod 55 and the waterproof cover 51.

[0035] An electrical box 7 is fixedly connected to the top of the triangular base 1. Inside the electrical box 7, there are built-in circuit devices such as a controller, a storage battery, and related current stabilizers. After the solar photovoltaic panel 3 generates electricity, it is stored in the storage battery through circuits such as the current stabilizer. The power in the storage battery is controlled by the controller and supplied for use during the maintenance of the wind power monitoring system. At the same time, the controller is also electrically connected to the reduction motor 53 and the water pump 64 to control them. As for the start, stop, and running time of the reduction motor 53 and the water pump 64, they can be set in advance in the controller. For example, it can be set to run once a day for 5 minutes each time, and the specific running time can be set according to requirements. The above-mentioned controller, storage battery, and related circuit devices are all prior arts, so no more details will be described here.

[0036] Embodiment 2 A power supply method for a floating offshore wind power monitoring system provided by the present invention includes: The wind power equipment 2 and the solar photovoltaic panel 3 generate electricity and store it respectively. As the solar photovoltaic panel 3 is used for a long time, when seawater scale and bird droppings are attached to its surface, the multi-directional driving device 5 is started, and it drives the three descaling devices 4 to scrape off the seawater scale and bird droppings attached to the surface of the solar photovoltaic panel 3. At the same time, the flushing device 6 is started to spray seawater onto the solar photovoltaic panel 3 to humidify and soften the seawater scale and bird droppings on the surface of the solar photovoltaic panel 3, so that the descaling device 4 can scrape off the debris on the surface of the solar photovoltaic panel 3.

[0037] Among them, inside the electrical box 7, there are built-in circuit devices such as a controller, a storage battery, and related current stabilizers. After the solar photovoltaic panel 3 generates electricity, it is stored in the storage battery through circuits such as the current stabilizer. The power in the storage battery is controlled by the controller and supplied for use during the maintenance of the wind power monitoring system. As the solar photovoltaic panel 3 is used for a long time, when seawater scale and seagull droppings and other debris are attached to its surface, the controller in the electrical box 7 can automatically drive the descaling device 4, the multi-directional driving device 5, and the flushing device 6 to operate.

[0038] When the multi-directional drive device 5 is in operation, the reduction motor 53 therein needs to be started. The output shaft of the reduction motor 53 rotates through the first bevel gear 54 and the three second bevel gears 56 to drive the three transmission rods 55 to rotate at the same speed. When the transmission rod 55 rotates, it drives the two threaded rods 42 to rotate at the same speed and in the same direction through the second sprocket 57, the chain 44 and the two first sprockets 43. When the threaded rod 42 rotates, the threaded sleeve 46 will move along the threaded rod 42 with the water box 61. When the water box 61 moves, it will also move synchronously with the scraper 47 and scrape off the seawater scale and bird droppings attached to the surface of the solar photovoltaic panel 3 through the scraper 47. The water pump 64 will also be started. The water inlet of the water pump 64 directly draws seawater from local materials through the suction pipe 65, and then guides the seawater to three hoses 63 through the connecting pipe 66. The hose 63 then guides the seawater into the water box 61 and sprays it to the solar photovoltaic panel 3 through multiple nozzles 62. After the seawater is sprayed onto the solar photovoltaic panel 3, the seawater scale and bird droppings on the surface thereof can be humidified and softened, so that the scraper 47 can more easily scrape off the debris on the surface of the solar photovoltaic panel 3. When scraping off the debris, the scraper 47 will also scrape off the seawater sprayed on the surface of the solar photovoltaic panel 3, so there will be no problem of scaling of the seawater used for cleaning and humidification again.

[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
