[0040] In the present application, the drone may be a remote-controlled flying device. The far end in the present application refers to the drone's center of mass and its perpendicular line as reference. The closer is called the proximal end, and the farther is called the far end.
[0041] In this application, if Figure 1 As shown, a patrol drone includes: a bracket 6, which is arranged below the drone body 4, and the bracket is also connected to a telescopic module 3, which includes a telescopic rod, and a detection module is arranged at the far end of the telescopic rod. Figure 4The detection module includes a detection rod 2, a conductor 1 is arranged at the top of the detection rod 2, the conductor 1 is connected to the wire 13, and the wire 13 passes through the detection rod 2 from the inside; a counterweight module 5, the counterweight module 5 is arranged at the other end of the telescopic module 3, the counterweight module 5 includes a counterweight telescopic rod, and the end of the counterweight telescopic rod away from the counterweight telescopic rod is also provided with: a counterweight block 55. Among them, the conductor 1 can include an ordinary metal body, or it can be a detection circuit integrating several components. In some specific embodiments, the drone can be used for inspection and flaw detection of wind turbine blades. For example, the conductor 1 is a resistance meter. The conductor 1 is contacted with the lightning protection point of the blade, and the resistance value of the lightning protection point can be measured to obtain a qualified test result. After the wire 13 passes through the detection rod 2 from the inside, it can be connected to the detection mechanism at the rear end to reduce the exposure of the wire 13 at the detection rod 2. Therefore, the safety of the inspection drone can be improved. The counterweight module 5 can be located in the same straight line with the detection rod 2 and the telescopic rod, and the detection module and the counterweight module 5 are respectively located at one end and the other end of the telescopic module 3. The counterweight module 5 is arranged at the other end of the telescopic module 3, which can only represent the positional relationship, that is, the counterweight module 5 is arranged at the other end of the telescopic module 3. The counterweight module 5 may not be fixed to the telescopic module 3, the counterweight module 5 is fixed to one of the brackets 6 of the drone, and the telescopic module 3 is fixed to the other bracket 6 of the drone. The extension direction of the counterweight telescopic rod is opposite to the extension direction of the telescopic module 3, so as to achieve the effect of balancing the torque. The weight of the counterweight block 55 can also be adjusted as needed. For example, a heavier counterweight block 55 can be configured, and the purpose of leveling can be achieved with a shorter stroke of the counterweight telescopic rod. The technical solution of the present application can change the torque of the counterweight block 55 by providing a counterweight module 5. When the working telescopic module 3 is extended, the counterweight telescopic rod can be adjusted to allow the drone to better maintain balance. On the other hand, the wire can pass through the inside of the detection rod 2, which can better protect the wire and increase its service life.
[0042] In one embodiment of the present application, please refer to Figure 2In order to achieve the telescopic effect, the telescopic rod includes: a first screw rod 33, one end of the first screw rod 33 is connected to a first motor 34, the first motor 34 is used to drive the first screw rod 33 to rotate, the distal end of the first screw rod 33 is connected to a first moving sleeve 32, and the distal end of the first moving sleeve 32 is connected to the detection module. Among them, the screw rod is a structure that converts rotary motion into linear motion, or converts linear motion into rotary motion. The usual structure of the screw rod can be a threaded rod plus a peripheral movable structure, and the movable can be one of a nut, a threaded sleeve, and a ball nut. In some embodiments, the first movable sleeve 32 is connected to the movable of the first screw rod 33. The first movable sleeve 32 is sleeved on the outer periphery of the first screw rod 33 and can be extended and retracted with the rotation of the screw rod. In some preferred embodiments, as shown in the figure, a first fixed sleeve 31 is also sleeved outside the screw rod, and the first movable sleeve 32 is also arranged in the first fixed sleeve 31, so that it is not easy to deviate during extension and retraction, and has good stability.
[0043] In one embodiment of the present application, connecting the wire to the ground mechanism by wire can reduce costs and reduce data latency. However, the weight of the drooping wire at a high altitude cannot be ignored. In order to further reduce the torque of the drone's load, the first screw rod 33 is hollow inside, and the wire passes through the screw rod from the inside and then droops to the ground below the drone body.
[0044] This application Figure 3 In one embodiment shown, the counterweight telescopic rod includes: a second screw rod 53, one end of the second screw rod 53 is connected to a second motor 54, the second motor 54 is used to drive the second screw rod 53 to rotate, the distal end of the second screw rod 53 is connected to a second movable sleeve 52, and the distal end of the second movable sleeve 52 is connected to the counterweight block 55. The usual structure of the screw rod can be a threaded rod plus a peripheral movable structure, and the movable can be one of a nut, a threaded sleeve, and a ball nut. In some embodiments, the second movable sleeve 52 can be connected to the movable of the second screw rod 53. The second movable sleeve 52 is sleeved on the outer periphery of the second screw rod 53 and can be extended and retracted as the screw rod rotates. A second fixed sleeve 51 can also be provided on the outside of the second screw rod 53.
[0045] This application Figure 4 In some embodiments shown, the front end of the detection module includes: a buffer 12, and the buffer 12 is used to deform to absorb kinetic energy. Among them, the buffer 12 can be made of soft material, and the buffer can be selected from one of rubber, foam, latex, resin and other materials. The length of the buffer in the axial direction parallel to the detection rod is slightly longer than or equal to the length of the conductor 1 in the axial direction parallel to the detection rod, so that when the drone moves horizontally, the buffer first contacts or contacts the preset point with the conductor 1 at the same time.
[0046] Others such as Figure 4 In the illustrated embodiment, the front end of the detection module includes: an adhesive attachment 14, and the adhesive attachment 14 is used to attach the detection module to the detected position. The adhesive attachment can be independent of the buffer, and is arranged at the distal end of the detection module together with the buffer, such as setting the adhesive attachment as a magnet block, and the magnet block is arranged around the conductor at the distal end of the detection module. The adhesive attachment can also be set at the distal end of the buffer. For example, the buffer is a foam glue, and the outer layer of the foam glue is a layer of adhesive. The viscosity of the adhesive is moderate, and it can adhere to the surface of the detected object when it is close, and it can leave the object when the drone is far away or the telescopic component is extended. By setting the adhesive attachment, the contact of the conductive part can be effectively guaranteed, and the detection reliability can be improved.
[0047] In one embodiment of the present application, please continue to refer to Figure 4 The front end of the detection module includes a detection plate 11, which is concentrically arranged with the detection plate 2, and a buffer and / or adhesive are arranged at the front end of the detection plate. The detection plate increases the cross-sectional area of the front end of the detection module and provides an area for installing various components.
[0048] In one embodiment of the present application, please refer to Figure 4 A shock absorbing spring 15 is arranged between the detection plate and the conductor 1, and the buffer is arranged around the outer circumference of the conductor 1. The shock absorbing spring 15 is a compression spring 15, and when the conductor contacts the detected area, the shock absorbing spring 15 is compressed, providing pressure for the conductor to press against the detected area, so that the conductor contacts the detected area better.
[0049] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
