Description

Technical Field

[0001] The invention relates to the technical field of snow removal for power transmission lines, and in particular to a snow removal and knocking device for an unmanned aerial vehicle with a throwing function. Background Art

[0002] When the transmission line is covered with ice, the vertical load increases. At the same time, the uneven ice coverage of the wires on both sides of the tower will produce a certain longitudinal tension difference, making the stress of the tower more complicated and serious. In extreme cases, heavy snow and ice loads may cause the tower base to sink, tilt, burst, or even break and collapse. It can be seen that ice or snow covering the overhead transmission line will have an extremely serious impact on the use of the overhead transmission line, so it is necessary to remove ice or snow from the overhead transmission line in a timely manner.

[0003] At present, when removing ice and snow from overhead power transmission lines, heavy-loaded drones are used to carry snow removal rods to remove ice from the lines. Snow removal rods are arranged at the bottom of the drones, and the flight of the drone drives the snow removal rods to move and hit the overhead power transmission lines, causing the overhead power transmission lines to vibrate, so as to remove the ice and snow on the overhead power transmission lines.

[0004] However, most of the existing UAV snow removal devices cannot simultaneously control the swing of the snow removal rod and throw the snow removal rod when the snow removal rod is entangled with the overhead power transmission line, which leads to great limitations in the process of snow removal by using UAVs to carry snow removal rods, and has a certain impact on the snow removal work. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention proposes a drone snow-removing and knocking device with a throwing function to solve the technical problem raised in the above background technology that most of the existing drone snow-removing devices cannot simultaneously control the swing of the snow-removing rod and throw the snow-removing rod when the snow-removing rod is entangled with the overhead transmission line, which leads to great limitations in the process of snow removal by drones carrying snow-removing rods, affecting the snow removal efficiency.

During the movement of the slide frame, the connecting rope can be driven to move so that the snow removal rod can swing back and forth to strike the overhead power transmission line, thereby clearing the snow on the overhead power transmission line. In this way, when the snow removal rod is carried by the drone body to remove snow, there is no need to control the drone body to fly within a larger range to achieve snow removal work, so that the drone body can still perform snow removal work when the movement is restricted, thereby improving the efficiency of snow removal.

[0034] When the snowplow stick or the connecting rope becomes entangled with other objects such as overhead power lines or tree branches in the snow removal area, the remote control servo can be reversed. During the rotation of the servo in the second direction, the connection between the locking assembly and the connecting rope is released through the throwing mechanism, so that the snowplow stick can be thrown, thereby preventing the drone body from crashing, effectively reducing work costs, and reducing the limitations of snow removal using the device.

[0051] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0052] Example:

[0053] like Figure 1 , 2 As shown in , 3, the present invention provides a UAV snow removal and knocking device with a throwing function, which is used to be installed on the UAV body 101 for use, including a mounting rod 102, the mounting rod 102 is detachably arranged at the bottom of the UAV body 101, and a mounting shell 201 is arranged on the mounting rod 102, and a steering gear 501 is arranged in the mounting shell 201, and the output shaft of the steering gear 501 can rotate in a first direction and a second direction, and the first direction is opposite to the second direction. The end of the snow removal rod 702 is provided with a connecting rope 701, and the connecting rope 701 is connected to the mounting shell 201 through a locking assembly. A sliding frame 607 is also provided on the mounting shell 201 to slide back and forth, and the connecting rope 701 is inserted into the sliding frame 607.

[0054] The locking assembly includes a locking frame 203 arranged on the mounting shell 201, the locking frame 203 is U-shaped, and a mounting sleeve 204 is arranged at one end of the locking frame 203. The locking rod 301 is slidably arranged in the mounting sleeve 204 along its axis and abuts against the other end of the locking frame 203. A connecting ring 703 is arranged at the end of the connecting rope 701, and the connecting ring 703 is sleeved on the locking rod 301.

[0055] During use, the connection ring 703 is installed by abutting the locking rod 301 against the locking frame 203, so that the snow removal rod 702 can be carried by the drone body 101 to remove snow from the overhead power transmission line. The locking rod 301 can be controlled to slide in the installation sleeve 204, so that the connection ring 703 is separated from the locking frame 203 under the gravity of the snow removal rod 702 and passes through the sliding frame 607, so that the snow removal rod 702 can be thrown.

[0056] like Figure 1 , 2 As shown in Figures 3 and 7, in the present embodiment, the output shaft of the servo 501 is connected to the slide frame 607 via a driving mechanism, and the driving mechanism is used to convert the rotation of the servo 501 in a first direction into driving the slide frame 607 to slide back and forth, and the driving mechanism includes a first gear 503 arranged on the output shaft of the servo 501, a second gear 601 is rotatably arranged on the mounting shell 201, the second gear 601 is meshed with the first gear 503, a driving column 602 is eccentrically arranged on the second gear 601, the driving column 602 and the slide frame 607 are connected via a connecting rod assembly, and the circumferential motion of the driving column 602 is converted into driving the slide frame 607 to reciprocate along the extension direction of the limiting groove 202 via the connecting rod assembly.

[0057] The connecting rod assembly includes a first connecting rod 603, a second connecting rod 605 and a third connecting rod 606. One end of the first connecting rod 603 is hinged to the driving column 602, one end of the second connecting rod 605 is hinged to the mounting column 604 on the mounting shell 201, the first connecting rod 603 is hinged to the middle section of the second connecting rod 605, one end of the third connecting rod 606 is hinged to the end of the second connecting rod 605, and the other end is hinged to the sliding frame 607. The mounting shell 201 is provided with a limiting groove 202, and the sliding frame 607 is slidably arranged in the limiting groove 202.

[0058] The steering engine 501 can be controlled to rotate in the first direction to drive the first gear 503 to rotate. The first gear 503 drives the driving column 602 on the second gear 601 to move in a circular manner through meshing with the second gear 601 during the rotation process. The driving column 602 drives the second connecting rod 605 to swing back and forth along the installation column 604 through the first connecting rod 603 during the movement, and drives the sliding frame 607 to slide back and forth along the limiting groove 202 through the hinge connection with the third connecting rod 606. The first connecting rod 603, the second connecting rod 605 and the third connecting rod 606 cooperate to enable the sliding frame 607 to move in a larger range under a limited installation environment, so as to control the reciprocating swing of the connecting rope 701. The connecting rope 701 can make the snow removal rod 702 swing within a certain range during the movement process, so as to knock and remove snow from the overhead power transmission line. In addition, it can be understood that the connecting rope 701 can be selected as a rope with a certain toughness, such as a wire rope, so that the movement control of the snow removal rod 702 is more stable.

[0059] like Figure 3 , 4 As shown in Figures 6 and 7, in this embodiment, a throwing mechanism is provided on the output shaft of the servo 501, and the rotation of the servo 501 in the second direction is converted into releasing the connection between the locking assembly and the connecting rope 701 through the throwing mechanism. The throwing mechanism includes a ratchet 502 provided on the output shaft of the servo 501, the ratchet 502 is coaxially fixedly connected with the first gear 503, a connecting rod 304 is provided at the end of the locking rod 301, and a limiting column 305 is provided at the end of the connecting rod 304, a first mounting groove 403 is provided on the movable frame 402, the movable frame 402 is slidably sleeved on the limiting column 305 through the first mounting groove 403, and the movable frame 402 will not be separated from the limiting column 305 under the action of the limiting bolt at the end of the limiting column 305, and a ratchet bar 401 is provided on the movable frame 402, and the ratchet bar 401 is meshed with the ratchet 502.

[0060] When the snow removal rod 702 or the connecting rope 701 is entangled with an overhead power transmission line or a tree branch, the output shaft can be rotated in the second direction by controlling the servo 501 to reverse. The forward and reverse control and remote control technology of the servo 501 are commonly used technical means for those skilled in the art, and will not be described here. When the servo 501 rotates forward, the ratchet 502 pushes the ratchet bar 401 to slide along the first mounting groove 403, thereby not driving the locking rod 301 to move, so as to ensure the stable fixation of the connecting ring 703. When the servo 501 reverses, it drives the ratchet 502 to reverse, and drives the ratchet bar 401 to slide through the cooperation of the ratchet 502 and the ratchet bar 401, and then drives the connecting rod 304 and the locking rod 301 to move, so that the locking rod 301 is separated from the connecting ring 703, and the snow removal rod 702 can be thrown to avoid the crash of the drone body 101.

[0061] like Figure 3 As shown, in this embodiment, an abutment plate 302 is provided on the connecting rod 304, an abutment seat 205 is provided on one side of the mounting shell 201, and a first elastic member 303 is provided between the abutment plate 302 and the abutment seat 205. The arrangement of the first elastic member 303 enables the locking rod 301 to stably abut against the locking frame 203 to stably fix the snow removal rod 702. In the process of controlling the connecting rod 304 to slide and throw the snow removal rod 702, the first elastic member 303 is compressed by the abutment plate 302, and an opening slot 306 is provided on the abutment plate 302, and the locking rod 301 can be driven to slide by toggling the opening slot 306, and the locking rod 301 is controlled to automatically reset under the reset ability of the first elastic member 303, so as to facilitate the installation and removal of the snow removal rod 702.

[0062] like Figures 3 to 6As shown, in this embodiment, a limit frame 404 is slidably mounted on the ratchet bar 401, and the limit frame 404 is slidably mounted on the mounting shell 201, and a connecting plate 405 is mounted on the limit frame 404, and a second elastic member 406 is mounted between the connecting plate 405 and the inner wall of the mounting shell 201. The movement of the ratchet bar 401 is positioned by the limit frame 404 to prevent the ratchet bar 401 from tilting or misaligning and disengaging from the ratchet wheel 502, and a stable thrust is applied downward to the ratchet bar 401 by the second elastic member 406 to ensure that the ratchet bar 401 can be stably mounted on the ratchet wheel 502, thereby improving the stability of the internal structure of the device to ensure stability during snow removal and casting.

[0063] like Figure 3 , 4 As shown, in the present embodiment, a stop block 206 is provided on one side of the mounting shell 201, and a stop switch 207 is provided on one side of the stop block 206. The stop switch 207 is electrically connected to the servo 501. When the locking rod 301 slides, the movable frame 402 can abut against the stop switch 207 to control the servo 501 to automatically stop starting after the snow removal rod 702 is thrown. There is no need to manually control the servo 501 to stop, thereby preventing the servo 501 from continuing to rotate and causing damage to its internal structure, thereby improving the service life of the device.

[0064] Specific usage and beneficial effects of the present invention:

[0065] When in use, the device can carry the snow removal rod 702 through the drone body 101, and can be rotated by the remote control servo 501. During the rotation of the servo 501 in the first direction, the engagement of the first gear 503 and the second gear 601 can drive the driving column 602 to move in a circular direction. During the movement, the driving column 602 drives the second connecting rod 605 to swing back and forth along the mounting column 604 through the first connecting rod 603, and then controls the sliding frame 607 to slide back and forth on one side of the mounting shell 201 through the cooperation of the second connecting rod 605 and the third connecting rod 606. During the movement, the sliding frame 607 can drive the connecting rope 701 to move so that the snow removal rod 702 swings back and forth to knock the overhead power transmission line, thereby clearing the snow on the overhead power transmission line. In this way, when the snow removal rod 702 is carried by the drone body 101 to remove snow, it is not necessary to control the drone body 101 to fly in a larger range to achieve snow removal, so that the drone body 101 can still remove snow when its movement is restricted, thereby improving the efficiency of snow removal.

[0066] When the snow removal rod 702 or the connecting rope 701 becomes entangled with other objects such as overhead power lines or tree branches in the snow removal area, the remote control servo 501 can be reversed. The servo 501 drives the ratchet 502 to rotate during the rotation in the second direction, and then the locking rod 301 is driven to slide in the mounting sleeve 204 through the cooperation of the ratchet 502 and the ratchet bar 401, thereby releasing the connection between the locking rod 301 and the connecting rope 701, thereby throwing the snow removal rod 702, thereby preventing the drone body 101 from crashing, effectively reducing the working cost, and reducing the limitations of snow removal by the device.

[0067] 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. On the basis of the present invention, some modifications or improvements can be made thereto, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
