Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to the integrated utilization technology of photovoltaic power generation and energy storage. [Background Technology]

[0002] In an environment with diverse installation methods for photovoltaic (PV) power stations, mounting them on power transmission towers is quite common. Referring to Chinese invention patent application publication number CN114844447A, a rotating and retractable integrated photovoltaic angle steel tower system is disclosed. This system includes a shared foundation for support, an angle steel tower and a rotating shaft fixedly mounted on the foundation, a rotating component on the rotating shaft to drive its rotation, and an electrical connection to a controller. A photovoltaic support frame is fixedly mounted on the rotating shaft, and several photovoltaic modules are fixedly mounted on the support frame. A portion of the electricity generated by the photovoltaic modules powers the equipment in the system, while the surplus electricity is fed into the local power distribution network. This system primarily utilizes the permanent land acquisition margin already acquired during the construction phase of the transmission tower to install distributed photovoltaic systems, fully utilizing the permanent land acquisition area of ​​the tower, eliminating the need for land use approval procedures during the construction phase of the distributed photovoltaic power station, reducing engineering investment, and alleviating the land shortage problem associated with distributed photovoltaic systems. However, the installation locations of the transmission towers are in remote deserts, forests, and other areas where it is inconvenient for people to conduct inspections. They also occupy a large area and are very tall (110 kV is about ten meters above the ground, 220 kV and 330 kV are about twenty meters, 500 kV is thirty or forty meters, 750 kV is about fifty meters, and 1000 kV is seventy or eighty meters). This causes difficulties for power inspection personnel and photovoltaic power stations, which is also the main reason why photovoltaic power stations installed on transmission line towers have not been widely promoted. [Utility Model Content]

[0003] To address the shortcomings of existing technologies, the technical problem this utility model aims to solve is to provide a photovoltaic power generation and energy storage integrated utilization system installed on power transmission line towers, which can be combined with inspection drones to solve the inspection problems of power transmission lines and photovoltaic power stations.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A photovoltaic power generation and energy storage integrated utilization system installed on a power transmission line tower includes a photovoltaic power station and an integrated multi-functional compartment. The integrated multi-functional compartment is located below the power transmission line tower and contains an energy storage device and a drone charging cabinet. The drone charging cabinet has a drone parking platform, and the drone parking platform has a charging module. The energy storage device is connected to the charging module and is used to store the electrical energy generated by the photovoltaic power station and to use the stored electrical energy to charge the drone.

[0006] Preferably, the top of the integrated multi-functional cabin is equipped with a skylight corresponding to the drone charging cabinet.

[0007] Preferably, the top of the integrated multi-functional cabin is equipped with sensors for detecting the approach of drones.

[0008] Preferably, the charging module is a magnetic charging dock.

[0009] Preferably, the integrated multi-functional cabin is also equipped with secondary equipment and / or a 5G network module, and the energy storage device supplies power to the secondary equipment and / or the 5G network module.

[0010] Preferably, the integrated multi-functional cabin has a door on the front and an escape door on the left or right side; and / or, the integrated multi-functional cabin is connected to a grounding wire.

[0011] Preferably, the integrated multi-functional cabin integrates an air conditioner and / or a ventilation fan.

[0012] Preferably, the integrated multi-functional cabin integrates a fire protection system and / or an access control system and / or a video surveillance system.

[0013] Preferably, the photovoltaic power station includes a photovoltaic support frame and photovoltaic modules installed on the photovoltaic support frame. Several photovoltaic modules are arranged in a rectangular array, and the photovoltaic modules are installed facing south and have an angle with the horizontal plane.

[0014] Preferably, the photovoltaic bracket is installed at the bottom of the power transmission line tower and above the integrated multi-functional compartment.

[0015] The present invention adopts the above technical solution and has the following beneficial effects:

[0016] 1. The photovoltaic power station is installed on the power transmission line tower, and the integrated multi-functional compartment is located below the power transmission line tower. The integrated multi-functional compartment can integrate energy storage devices and drone charging cabinets. By installing the photovoltaic power station on the power transmission line tower, land occupation can be avoided. In addition, the land below the tower is effectively utilized to place the integrated multi-functional compartment, making reasonable use of the land below the tower and avoiding additional land investment.

[0017] Because the integrated multi-functional cabin integrates an energy storage device and a drone charging cabinet, and the drone charging cabinet is equipped with a drone parking platform, which in turn is equipped with a charging module, the photovoltaic power station can be used to charge the energy storage device during the day, and the stored electrical energy can be used to charge the drone at night.

[0018] Current drone inspection methods involve personnel driving hundreds of kilometers to reach the vicinity of power transmission lines before using drones for inspection. Since drone charging cabinets can both park and charge drones, drones can periodically take off from their parking platforms for inspections, with an inspection radius of up to 5km. Installing a photovoltaic power generation and energy storage integrated system within 10km of the power transmission lines can meet the drone inspection needs, mitigating potential hazards for maintenance personnel. Furthermore, drones can be operated from home or the office, saving on vehicle operating costs and personnel time compared to the current method of drones taking off from vehicles, thus improving economic efficiency.

[0019] 2. Since the top of the integrated multi-functional cabin has a skylight corresponding to the drone charging cabinet, the skylight can be opened to allow the drone to enter or exit when it needs to be launched or retrieved, and closed when the drone is parked. Furthermore, the automatic opening and closing mechanism of the skylight can be referenced from existing technologies to achieve automatic control of the skylight's opening and closing.

[0020] 3. Since the top of the integrated multi-functional cabin is equipped with sensors to detect the approach of drones, the skylight is opened only when the drone is close.

[0021] 4. A magnetic charging dock can be used to charge the drone. Magnetic charging uses magnetic force to attach the charger and device together for charging. It is suitable for charging mobile devices and has strong stability and reliability. Of course, wireless charging can also be used.

[0022] 5. The integrated multi-functional cabin is also equipped with secondary equipment and / or a 5G network module, so the energy storage device can also supply power to the secondary equipment and / or the 5G network module.

[0023] 6. The integrated multi-functional cabin is fully equipped with air conditioning, ventilation fans, fire protection systems, access control systems, video surveillance systems, and lights, ensuring reliable operation of the integrated multi-functional cabin.

[0024] 7. The photovoltaic bracket is installed at the bottom of the power transmission line tower and above the integrated multi-functional compartment. The height is not high to facilitate installation and maintenance, and to ensure a safe distance from the transmission line.

[0025] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

[0034] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0035] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0036] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "left," and "right" that indicate orientation or positional relationship are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] Reference Figures 1 to 6 As shown, the photovoltaic power generation and energy storage integrated utilization system installed on the power transmission line tower in this embodiment includes a photovoltaic power station 2 and an integrated multi-functional cabin 1. The integrated multi-functional cabin 1 is located below the power transmission line tower 3. The integrated multi-functional cabin 1 includes a cabin body 100, and an energy storage device 12 and a drone charging cabinet 11 are provided inside the cabin. The drone charging cabinet 11 is provided with a drone parking platform, and the drone parking platform is provided with a charging module. The energy storage device 12 is connected to the charging module and is used to store the electrical energy generated by the photovoltaic power station 2 and use the stored electrical energy to charge the drone.

[0039] Installing photovoltaic power stations on power transmission line towers avoids occupying land. In addition, the land under the tower is used to place integrated multi-functional cabins, making reasonable use of the land under the tower and avoiding additional land investment.

[0040] Because the integrated multi-functional cabin integrates an energy storage device and a drone charging cabinet, and the drone charging cabinet is equipped with a drone parking platform, which in turn is equipped with a charging module, the photovoltaic power station can be used to charge the energy storage device during the day, and the stored electrical energy can be used to charge the drone at night.

[0041] Current drone inspection methods involve personnel driving hundreds of kilometers to reach the vicinity of power transmission lines before using drones for inspection. Since drone charging cabinets can both park and charge drones, drones can periodically take off from their parking platforms for inspections, with an inspection radius of up to 5km. Installing a photovoltaic power generation and energy storage integrated system within 10km of the power transmission lines can meet the drone inspection needs, mitigating potential hazards for maintenance personnel. Furthermore, drones can be operated from home or the office, saving on vehicle operating costs and personnel time compared to the current method of drones taking off from vehicles, thus improving economic efficiency.

[0042] The integrated multi-functional compartment 1 can integrate several functional modules. These modules can utilize existing technologies. For example, the energy storage device 12 and the charging module mentioned above can both employ existing technologies. The energy storage device can use a lithium battery for energy storage, and the charging module can use a magnetic charging base. Magnetic charging is a method that uses magnetic attraction to attach the charger and device together for charging. It is suitable for charging mobile devices and has strong stability and reliability. Of course, wireless charging can also be used.

[0043] It is understood that the integrated functional modules of the multi-functional cabin 1 can be expanded. As one embodiment, the cabin body 100 of the multi-functional cabin 1 also includes secondary equipment 13 and a 5G network module. The secondary equipment includes a DC integrated power supply panel and a data scheduling network panel. The 5G network module enables remote wireless communication, allowing data interaction between the multi-functional cabin 1 and a remote location. Furthermore, the energy storage device 12 supplies power to the secondary equipment and the 5G network module.

[0044] Furthermore, the top of the integrated multi-functional cabin 1 is equipped with a skylight (not shown in the figure) corresponding to the drone charging cabinet. The top of the integrated multi-functional cabin 1 is equipped with a sensor for detecting the approach of a drone. Because the top of the integrated multi-functional cabin is equipped with a skylight corresponding to the drone charging cabinet, the skylight can be opened to allow the drone to enter or exit when it needs to be launched or retrieved; the skylight closes when the drone is parked. Moreover, the automatic opening and closing mechanism of the skylight can be referenced in existing technology to achieve automatic control of the skylight's opening and closing. Since the top of the integrated multi-functional cabin is equipped with a sensor for detecting the approach of a drone, the skylight is only opened when the drone approaches.

[0045] Because the integrated multi-functional cabin 1 needs to meet both equipment operation requirements and personnel maintenance and activity requirements, it has a door 101 on the front side of its body 100 and an escape door 102 on either the left or right side. A grounding wire is also connected to the bottom of the cabin body. Furthermore, the integrated multi-functional cabin 1 integrates an air conditioner 14 and a ventilation fan 15. The air conditioner is installed on the left side wall of the cabin and can be an industrial air conditioner. The ventilation fan is installed on the right side wall of the cabin and can be an axial flow fan with an air volume of 2300 m³ / h. 3 / h can meet the ventilation requirements and can work at set intervals to perform ventilation, such as once every 3 minutes.

[0046] Furthermore, the integrated multi-functional cabin 1 integrates a fire protection system 18, an access control system, a lighting system 16, and a video surveillance system 17, all of which directly adopt existing technologies.

[0047] Specifically, the integrated multi-functional cabin structure is a single-unit design, similar to that of a shipping container. The dimensions of the integrated multi-functional cabin are 5000mm*3000mm*3200mm. The overall frame of the cabin is constructed from welded steel structural components; for example, the four corner posts and door posts are made of square steel tubing, while the bottom and top frames use channel steel. Additionally, the walls use 1.6mm corrugated board with 50mm thick rock wool insulation, and the interior walls are decorated with metal carved panels, achieving an IP54 protection rating. The total wall thickness is 100mm. The interior floor is raised by 200mm and covered with anti-static flooring. The cabin roof uses 1.6mm corrugated board with double-sided slope and rock wool insulation, and the interior is decorated with metal carved panels. The cabin door is a flat panel door with built-in rock wool, and the escape door is equipped with a push-bar escape lock. The cabin also has pre-drilled access holes for cabling.

[0048] Referring to existing technology, the photovoltaic power station includes a photovoltaic support structure and photovoltaic modules installed on the support structure. Several photovoltaic modules are arranged in a rectangular array, facing south and at an angle to the horizontal plane to improve power generation efficiency. The photovoltaic support structure is installed at the base of the power transmission line tower and above the integrated multi-functional compartment. Its height is not high to facilitate installation and maintenance, and also to ensure a safe distance from the transmission line.

[0049] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
