Description

Technical Field

[0001] The present invention relates to the field of power transmission line deicing, and in particular to an unmanned aerial vehicle deicing agent spraying device used for power transmission line inspection and deicing. Background Art

[0002] The UAV deicing spraying device for inspection and deicing of transmission lines is a device specially designed to remove snow and ice on transmission lines. The existing UAV deicing spraying device for inspection and deicing of transmission lines lifts the UAV to a suitable working position and sprays atomized deicing agent through the atomizing nozzle connected to the storage box, thereby realizing the melting of ice on the transmission line. In order to spray and de-ice multiple high-voltage lines at the same time, multiple atomizing nozzles are generally installed and their spacing is adjusted to achieve simultaneous spraying and de-icing of multiple high-voltage lines. However, the spacing of the transmission lines in the transmission line network is not fixed. When the spacing of the transmission lines changes, the operator needs to land the UAV on the ground and manually use tools to adjust the spacing of the atomizing nozzles to meet the spraying and de-icing of transmission lines with different spacings. This not only increases the operation time, but also increases the loss of the UAV due to frequent take-offs and landings. Each adjustment requires stopping, landing, adjusting, and taking off again, which greatly reduces the work efficiency and increases the safety risk of the operator. Especially in severe weather conditions, frequent adjustments and maintenance will increase manpower and material costs and reduce the overall economic benefits. Summary of the invention

[0003] The present invention provides an unmanned aerial vehicle (UAV) de-icing agent spraying device for inspection and de-icing of transmission lines. By setting an adjustment mechanism, the spacing between atomizing nozzles can be quickly and flexibly adjusted without the need for the UAV to land, thereby extending the service life of the equipment and meeting the requirements of spraying and de-icing a plurality of transmission lines at different spacings, thereby greatly improving operating efficiency, reducing unnecessary downtime and manpower, and reducing overall operating costs.

[0007] Furthermore, the connecting plate is provided with a first through hole and a second through hole adapted to the telescopic hose and the sliding frame, the telescopic hose and the sliding frame respectively pass through the first through hole and the second through hole, and the sliding frame is slidably connected to the connecting plate.

[0008] Furthermore, the thread directions of the two screw rods are arranged in opposite directions.

[0009] Furthermore, the mounting mechanism includes mounting units symmetrically arranged on both sides of the mounting frame, each mounting unit includes a connecting frame arranged parallel to the mounting frame, a plurality of columns arranged between the mounting frame and the connecting frame, a plurality of rectangular blocks arranged on the upper surface of the connecting frame, and a pull plate arranged parallel to the connecting frame, the two ends of the columns are respectively detachably connected to the mounting frame and the connecting frame, a locking column is slidably connected to the middle part of each rectangular block, a spring is sleeved on the outer arc surface of the locking column, and the other end of the spring is connected to the pull plate.

[0010] Furthermore, the drone is provided with a locking hole adapted to the locking column, and the locking column is inserted into the locking hole.

[0011] Furthermore, a stirring mechanism is provided inside the liquid storage tank, and a first motor electrically connected to the control panel is provided on the upper surface of the liquid storage tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1) The control panel is used to control the opening of the first solenoid valve, and then the appropriate volume of deicing liquid can be added through the liquid inlet pipe, and high-pressure gas is injected into the interior thereof. Then, the control panel is used to control the closing of the first solenoid valve, and then the spraying device is installed on the drone, and then the drone is launched to reach a suitable deicing operation airspace, and the atomizing nozzle is directed toward two transmission lines. Then, the control panel is used to control the opening of the second solenoid valve, so that the deicing liquid inside the storage tank is transported by the high-pressure gas at high speed through the telescopic hose and sprayed onto the transmission line through the atomizing nozzle, thereby quickly achieving simultaneous deicing of multiple transmission lines;

Since the screw rods on both sides have opposite threads, the rotating frames on both sides move closer or farther away from each other, and the connecting rods on both sides rotate to expand and contract, thereby driving the atomizing nozzles on the sliding frames on both sides to move closer or farther away, thereby realizing flexible adjustment of the spacing between the atomizing nozzles, and the de-icing operation of spraying de-icing agents on transmission lines with different spacings can be completed simultaneously without the need for drone landing. The service life of the equipment is extended while meeting the need for spraying and de-icing of multiple transmission lines with different spacings, greatly improving the operating efficiency, reducing unnecessary downtime and manpower, and reducing the overall operating cost.

[0016] 3) When the spraying device needs to be installed on the drone mounting frame, the pull plates on both sides are pulled to move the locking columns on both sides away from each other. At this time, the spring is in a stretched state, and the mounting frame on the drone is moved between the two connecting rods so that the mounting locking holes on the drone mounting frame correspond to the positions of the locking columns on both sides. Then, the pull plate is released, and the spring rebounds quickly to drive the locking columns to be inserted into the mounting locking holes on the drone mounting frame, thereby realizing the rapid installation and removal of the spraying device and improving the work efficiency of personnel;

[0017] 4) The first motor is turned on by the control panel, and the output shaft drives the stirring blade on the rotating column to rotate, so as to stir the ice-melting agent liquid in the liquid storage tank, so as to prevent the ice-melting agent in the liquid storage tank from freezing due to the low temperature in a static state, resulting in the inability to spray the ice-melting agent, thereby ensuring the normal operation of the spraying device;

[0018] 5) The first motor, the second motor, the first solenoid valve and the second solenoid valve on the spraying device can be quickly controlled through the control panel, which is convenient for personnel to automatically control. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the pull plate 303 is released. At this time, the spring 305 rebounds quickly and drives the locking columns 304 to be inserted into the locking holes on the drone mounting frame, thereby realizing the rapid installation and disassembly of the spraying device.
