Description

Technical Field

[0001] The utility model relates to the technical field of wind farm patrols, and in particular to an unmanned aerial vehicle monitoring device used for wind farm patrols. Background Art

[0002] A wind farm utilizes wind energy and combines it with a series of generators to achieve the purpose of generating electricity using wind. In a wind farm, wind turbines are generally distributed over a wide area and in large numbers. In order to ensure the safe and stable operation of the wind farm, in addition to fixed monitoring, drone flight patrol monitoring is also required. In the process of monitoring and patrolling by drones, since drones usually fly at a high altitude, when encountering strong winds during the monitoring and patrol process, the drone monitoring device may lose control and crash. Since the monitoring device on the outside of the drone is usually directly fixed on the outside of the drone, when the drone loses control and crashes, the monitoring device will also crash with the drone. Therefore, in response to the above problems, a drone monitoring device for patrolling wind farms is proposed. Utility Model Content

[0003] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A drone monitoring device for patrolling a wind farm comprises a drone, wherein the bottom end of the drone contacts a fixed plate, the top left side of the fixed plate is fixedly connected to a controller and a receiver arranged up and down, the top inner side of the fixed plate is slidably connected to a slider, the bottom inner side of the slider is provided with a clamping block, the bottom outer side of the clamping block is clamped and connected to a fixed block slidably connected to the fixed plate, the right end of the fixed block is rotatably connected to a connecting block penetrating the fixed plate via a rotating shaft, and the connecting block is slidably connected to the fixed plate, the bottom end of the connecting block is fixedly connected to a monitor in contact with the fixed plate, the left end of the fixed block is fixedly connected to a parachute, the outer side of the parachute is provided with a sliding sleeve slidably connected to the fixed plate, and the sliding sleeve contacts the fixed block, and the left end of the sliding sleeve contacts a second spring.

[0008] As a further improvement of the utility model, both front and rear ends of the outer side of the sliding sleeve are fixedly connected to limiting blocks, and the limiting blocks are slidably connected to the fixed plate.

[0009] As a further improvement of the utility model, the left and right sides of the top end inside the fixed plate are rotatably connected with a bidirectional threaded shaft with opposite thread directions on both sides, and the bidirectional threaded shaft passes through the fixed plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. A drone monitoring device for patrolling a wind farm, which includes a second spring, a sliding sleeve, a parachute, a monitor, a fixed block, an electric push rod, a clamping block and a slider. When the device is used to patrol and monitor the wind farm, when the device encounters a strong wind at high altitude and falls out of control, the electric push rod is controlled to contract, and the slider further drives the clamping block to disengage from the fixed block. Then, the elastic force of the second spring in the compressed state is restored, and the sliding sleeve pushes the fixed block on the top of the monitor out of the fixed plate to the right, thereby separating the monitor from the drone. At the same time, the monitor pulls out the parachute in the sliding sleeve through the connecting block and the fixed block. At this time, the monitor drives the parachute to separate from the drone, thereby preventing the monitor from crashing along with the drone.

When the device is used, the fixed block at the top of the monitor is slid into the bottom inner side of the fixed plate, and then the fixed block and the clamping block are clamped together. Then the fixed plate is placed on the bottom of the UAV, and finally the bidirectional threaded shaft is rotated to be spirally connected with the clamping rod, so that the clamping rod further drives the clamping shaft to clamp the UAV together. At this time, it is convenient to connect the UAV and the monitor together through the separation mechanism, so that when the UAV loses control and crashes later, it is convenient to separate and protect the monitor.

Based on the specific implementation methods in the utility model, all other specific implementation methods obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, a UAV monitoring device for patrolling a wind farm comprises a UAV 1, wherein the bottom end of the UAV 1 contacts a fixed plate 2, and the top left side of the fixed plate 2 is fixedly connected with a controller 3 and a receiver 4 arranged up and down, the top inner side of the fixed plate 2 is slidably connected with a slider 6, the bottom inner side of the slider 6 is provided with a clamping block 8, the bottom outer side of the clamping block 8 is clamped and connected with a fixed block 9 slidably connected with the fixed plate 2, the right end of the fixed block 9 is rotatably connected with a connecting block 10 penetrating the fixed plate 2 through a rotating shaft, and the connecting block 10 is slidably connected with the fixed plate 2, the bottom end of the connecting block 10 is fixedly connected with a monitor 11 in contact with the fixed plate 2, the left end of the fixed block 9 is fixedly connected with a parachute 13, the outer side of the parachute 13 is provided with a sliding sleeve 12 slidably connected with the fixed plate 2, and the sliding sleeve 12 contacts with the fixed block 9, and the left end of the sliding sleeve 12 contacts with a second spring 14.

[0023] Example 2

[0024] like Figure 2 As shown, in order to solve the problem that it is inconvenient to quickly connect the monitor 11 to the bottom of the base plate 2, the right end of the card block 8 is inclined, and the card block 8 is slidably connected to the slider 6 and the fixed plate 2. The top of the card block 8 is fixedly connected to the first spring 7, and the other end of the first spring 7 is fixedly connected to the slider 6. By pushing the fixed block 9 at the top of the monitor 11 to slide into the bottom end of the inner side of the fixed plate 2, and then after the fixed block 9 contacts the card block 8, the card block 8 first compresses the first spring 7 and retracts it into the slider 6, and then resets and clamps it together with the fixed block 9, which facilitates the rapid connection of the monitor 11 to the bottom of the base plate 2.

[0025] Example 3

[0026] like Figure 2 and Figure 4 As shown, in order to solve the problem of inconvenience in determining whether fatigue deformation occurs to the second spring 14 before use, the left end of the second spring 14 contacts with a pressure plate 15, and a pressure sensor 16 is fixedly connected to the outside of the pressure plate 15, and the pressure plate 15 and the pressure sensor 16 are both in contact with the fixed plate 2, and a signal light 17 is fixedly connected to the bottom left end of the fixed plate 2. The second spring 14 is compressed by pushing the sliding sleeve 12 on the fixed block 9 and then locked together with the clamping block 8, so that the pressure plate 15 further presses the pressure sensor 16. At this time, whether the pressure value detected by the pressure sensor 16 is within the set range can further control the light of the signal light 17, which facilitates determining whether fatigue deformation occurs to the second spring 14 before use.

[0027] Example 4

[0028] like Figure 1-3 As shown, in order to solve the problem of inconvenience in connecting the fixing plate 2 to the bottom of the drone 1, the left and right sides of the top of the fixing plate 2 are rotatably connected with a bidirectional threaded shaft 18 with opposite thread directions on both sides, and the bidirectional threaded shaft 18 passes through the fixing plate 2, and the outer side of the bidirectional threaded shaft 18 is spirally connected with a clamping rod 19 slidably connected to the fixing plate 2, and one end of the outer side of the clamping rod 19 is fixedly connected with a clamping shaft 20. By placing the fixing plate 2 on the bottom of the drone 1, and then rotating the bidirectional threaded shaft 18 with opposite thread directions on both sides to be spirally connected with the clamping rod 19, the clamping rod 19 further drives the clamping shaft 20 to clamp with the drone 1, which facilitates the connection of the fixing plate 2 to the bottom of the drone 1.

[0029] Example 5

[0030] like Figure 2As shown, in order to solve the problem that it is inconvenient to automatically control the card block 8 to disengage from the fixed block 9, an electric push rod 5 is fixedly connected to the top of the slider 6, and the electric push rod 5 is fixedly connected to the fixed plate 2. By controlling the electric push rod 5 to retract, it is convenient to automatically control the card block 8 to disengage from the fixed block 9 through the slider 6.

[0031] In this embodiment, the monitor 11 in the device is powered by the built-in power supply of the monitor 11, and all other electrical appliances are powered by the built-in power supply of the drone. When the device is used to patrol and monitor the wind farm, the sensing range of the pressure sensor 16 is set by the controller 3. After setting, the fixing block 9 at the top of the monitor 11 is first slid into the bottom of the inner side of the fixing plate 2, so that the parachute 13 connected to the outer side of the fixing block 9 is located in the sliding sleeve 12. At this time, the fixing block 9 will first push the sliding sleeve 12 to compress the second spring 14 after contacting the sliding sleeve 12, and the pressure plate 15 will continuously press the pressure sensor 16. The first spring 7 is compressed by the pressure sensor 16, and then when the inclined surface of the fixing block 9 contacts the inclined surface of the card block 8, the card block 8 will first compress the first spring 7 and store it in the slider 6, and then the card block 8 will reset and be stuck together with the fixing block 9. During this process, the monitor 11 will continue to slide with the bottom of the fixing plate 2. When the card block 8 is stuck together with the fixing block 9, the sliding monitor 11 is positioned. After positioning, observe whether the signal light 17 is on. If the signal light 17 is on, it means that the pressure value sensed by the pressure sensor 16 is lower than the set range, the second spring 14 has aged, fatigue deformation has occurred, and the second spring 14 needs to be adjusted. The signal light 17 is not on, indicating that the second spring 14 is normal and the device can be used normally. When using the device, place the fixing plate 2 at the bottom of the drone 1, and then rotate the two-way threaded shaft 18 with opposite thread directions on both sides to screw it with the clamp rod 19, so that the clamp rod 19 further drives the clamping shaft 20 to clamp the drone 1 together. At this time, the drone 1 and the monitor 11 are connected together through the separation mechanism. When the device is used after the connection, when the device encounters a strong wind at high altitude and falls out of control, the external control mechanism is controlled to control the device. When the receiver 4 receives the control signal, the controller 3 will control the electric push rod 5 to contract, further causing the slider 6 to drive the block 8 to disengage from the fixed block 9, and then the elastic force of the second spring 14 in the compressed state will be restored, and the sleeve 12 will push the fixed block 9 on the top of the monitor 11 to the right out of the fixed plate 2, thereby separating the monitor 11 from the drone 1, and at the same time, the monitor 11 pulls out the parachute 13 in the sleeve 12 through the connecting block 10 and the fixed block 9. At this time, by causing the monitor 11 to drive the parachute 13 to separate from the drone 1, the monitor 11 is prevented from crashing along with the drone.
