Description

Technical Field

[0001] The utility model relates to the field of automatic charging of unmanned aerial vehicles in wind farms, and in particular to an automatic charging platform for unmanned aerial vehicles in wind farms. Background Art

[0002] Wind farms are built on mountain tops or plateaus, and the plant covers a wide area with rugged roads. When inspecting wind farms, drones are used for inspection. This inspection method is mature and has good inspection effects. However, the main difficulty of drone inspections is the endurance of drones. If workers carry mobile power supplies to charge drones after power outages, the drones need to fly back to the workers' work area when they are out of power. This distance is far, which will shorten the inspection area of ​​the drones during cruising.

[0003] Chinese Patent: Publication No. CN110588388A, titled wireless charging method for drone, drone and charging platform, discloses that a receiver, a transmitter, a wireless charging receiving circuit, a memory and a processor are set on the drone, and a receiver, a transmitter, a wireless charging transmitting circuit, a memory and a processor are set on the charging platform, so that the charging platform can charge the drone. Therefore, it provides a good charging method for the drone's endurance, so that the drone can be charged outdoors without the need for the drone to fly back to the workers' work area.

[0004] However, the above-mentioned charging platform is set up outdoors, and wireless charging is to wirelessly charge the drone by emitting electromagnetic waves. If the surface of the charging platform is dirty, it will block the electromagnetic waves and affect the charging effect. In addition, since the wind farm is built in a place with strong winds, a large amount of dust will adhere to the charging platform, which will cause greater obstacles. In addition, since the wind farm uses drones for inspection and no one has been there for maintenance for a long time, the charging platform cannot be set at a distance close to the ground as disclosed in CN110588388A.

[0005] Therefore, it is necessary to design an automatic charging platform that can be installed at a high place and can prevent dust from adhering. Utility Model Content

[0014] Furthermore, the opening and closing mechanism includes a driving motor, two screw rods and two screw rod slides. The two screw rods are rotatably installed on the back plate. The driving motor drives the two screw rods to rotate simultaneously through a gear set. The two screw rod slides are respectively engaged with the two screw rods. The two screw rod slides are respectively fixedly connected to the two protective covers.

DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0024] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0025] Reference Figures 1 to 5The shown type of automatic charging platform for unmanned aerial vehicles in a wind farm includes a back panel 1, a control box 2, a wireless charging mechanism, a solar power supply mechanism, an opening and closing mechanism 5 and two protective covers 4. The wireless charging mechanism is installed in the control box 2. The wireless charging mechanism includes a charging platform 3. The charging platform 3 passes through the top of the control box 2. The top of the charging platform 3 can be flush with the top of the control box 2, so that the unmanned aerial vehicle can have a sufficient landing platform. The back panel 1 is fixedly installed on one side of the control box 2. A bracket can be connected to the back panel 1 for fixing it on the top of the column of the wind turbine. Of course, it can also be fixedly installed on the ground, but the preferred method is the top of the column to reduce the amount of electricity required for the unmanned aerial vehicle to land, and at the same time, it also prevents the charging platform from being arbitrarily damaged by others. The opening and closing mechanism 5 is fixedly installed on the back panel 1. The opening and closing mechanism 5 is used to control the opening and closing of the two protective covers 4. The opening and closing mechanism 5 needs to be installed inside the protective cover 4 to prevent rain and dust from damaging the device. A battery is provided in the controller, and a solar power supply mechanism is used to charge the battery, which then supplies electricity to the charging platform. The drone is charged by electromagnetic waves. The charging method is an existing method that can be easily thought of by technicians in this field. A wireless charging receiving circuit is installed on the drone.

[0026] When charging the drone, the entire control process is as follows: through the transmission of wireless signals, the receiving module on the controller senses the wireless signal, and at this time, the opening and closing mechanism 5 is controlled to open the protective cover 4. The drone can fly onto the charging platform 3, and then the battery is controlled to power the charging platform 3, so that the charging platform 3 charges the drone. The battery power supply can be started when the wireless signal is received, or a proximity sensor or pressure switch can be set on the control box 2 to control the start.

[0027] The solar power supply mechanism comprises a plurality of photovoltaic panels 6 fixedly mounted on the protective cover 4. The photovoltaic panels 6 replace the protective panels of the protective cover 4, thereby reducing the weight of the entire device.

[0028] A dustproof cover plate 4 a is installed on the protective cover 4 . The dustproof cover plates 4 a on the two protective covers 4 are used to cover the charging platform 3 when closed, so as to further prevent dust from adhering to the charging platform 3 .

[0029] In order to allow the drone to enter the automatic charging platform for charging when it rains, the protective cover 4 must be closed and the dust cover 4a must not be retracted. Figure 3 and Figure 4As shown, an elastic seat 4b is provided on the protective cover 4, and the dust cover 4a is fixedly installed on the elastic seat 4b. A blocking mechanism 7 for limiting the dust cover 4a is provided in the control box 2. When the drone is charged on rainy days, the blocking mechanism 7 extends from the control box 2, limits and blocks the dust cover 4a, and then closes the two protective covers 4, so that the dust cover 4a cannot move together with the protective cover 4, that is, the dust cover 4a is prevented from colliding with the drone being charged.

[0030] The elastic seat 4b includes a guide post 4b1, a resistance spring 4b2 and a displacement plate 4b3. The displacement plate 4b3 is fixedly mounted on the dust cover plate 4a. The guide post 4b1 is fixedly mounted on the protective cover 4. The displacement plate 4b3 is slidably connected with the guide post 4b1. The resistance spring 4b2 is used to provide an elastic force for the resistance spring 4b2 to approach the charging platform 3. Through the elastic force of the resistance spring 4b2, when the blocking mechanism 7 does not block, the displacement plate 4b3 fits with the protective cover 4. On the contrary, when the blocking mechanism 7 blocks, the resistance spring 4b2 will be compressed. The protective cover 4 is provided with an avoidance gap for the dust cover plate 4a to pass through.

[0031] The blocking mechanism 7 includes a block 7a and an electric push rod 7b for pushing the block 7a up and down. The block 7a is used to block the dust cover 4a. There can be multiple blocks 7a, and the control box 2 is provided with a square guide hole for the block 7a to drive, and the square guide hole is used to limit the block 7a.

[0032] The opening and closing mechanism 5 includes a driving motor 5a, two screw rods 5b and two screw rod slides 5c. Both screw rods 5b are rotatably installed on the back plate 1. The driving motor 5a drives the two screw rods 5b to rotate simultaneously through a gear set. The two screw rod slides 5c are respectively engaged with the two screw rods 5b. The two screw rod slides 5c are respectively fixedly connected to the two protective covers 4. When the driving motor 5a drives the two screw rods 5b to rotate simultaneously, the two screw rod slides 5c can move synchronously to move closer to or away from each other. The tooth grooves on the two screw rods 5b are in opposite directions, and the same end of the two screw rods 5b is fixedly connected to a gear on the gear column. In order to save space, at least two gears are required. The protective cover 4 is limited between the back plate 1 and the control box 2 to prevent the protective cover 4 from rotating when it is driven by the opening and closing mechanism 5.

[0033] The wind farm drone automatic charging platform is closed by two protective covers 4, so that when the charging platform is installed at a high place, it can protect against dust and prevent dust from adhering to the charging platform 3. A dustproof cover 4a is used to further protect the charging platform 3, and the dustproof cover 4a is blocked by a blocking mechanism 7. In rainy days, the charging platform can still charge the drone.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
