[0057] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0058] Embodiment one

[0059] Referring to Figures 1-4 The present embodiment claims a spraying mechanism, which comprises a first support rod 20, a second support rod 21, a triangular support block 22, a first frame 23, a first steering engine 24, a first fixing frame 25, a second steering engine 26, a second fixing frame 27, a first pipeline 28, a wind shield 29, a nozzle 30 and a screw (not shown in the figure).

[0060] The first support rod 20 is hollow inside, and a set of second support rods 21 are symmetrically arranged on both sides of the first support rod 20. One end of the second support rod 21 is connected to the first support rod 20 through the triangular support block 22, and the other end of the second support rod 21 constitutes a suspended end of the second support rod 21. The suspended end of the second support rod 21 extends in a direction away from the first support rod 20, so that the set of second support rods 21 and the first support rod 20 are combined with each other to form a triangular support structure.

[0061] The number of the set of second support rods 21 is two, but it is not limited to two.

[0062] The triangular support refers to that, along the horizontal direction, the suspended end of the second support rod 21 is inclined away from the first support rod 20, and along the vertical direction, the suspended end of the second support rod 21 is inclined upward or downward away from the first support rod 20.

[0063] A first frame 23 is arranged at the end of the first supporting rod 20 close to the triangular supporting block 22, and the first frame 23 has a "U" shaped cross section. A first steering engine 24 is arranged in the first frame 23. The steering engine is a position or angle servo driver, which can accurately drive the mechanical structure to a specified angle according to the received control signal, and keep the stable position when the load changes. The steering engine is a known technology, and will not be described here.

[0064] The output end of the first steering engine 24 is connected to a first fixed frame 25, which includes two parts connected to each other. The first part has a "U" shaped cross section, and the second part has a "U" shaped cross section. The output end of the first steering engine 24 is connected to the two sides of the first part. At this time, the first fixed frame 25 can be adjusted to flip along the vertical direction by driving the first steering engine 24.

[0065] The second part is provided with a second steering engine 26, and the output end of the second steering engine 26 is connected to a second fixed frame 27. The second fixed frame 27 has a "U" shaped cross section, and the output end of the second steering engine 26 is connected to the two sides of the second fixed frame 27. At this time, the second fixed frame 27 can be adjusted to swing along the horizontal direction by driving the second steering engine 26.

[0066] A hexagonal slot 270 is arranged on the side of the second fixed frame 27 away from the second steering engine 26. A nozzle 30 has a spray head at one end. Two nuts 301 are engaged on the nozzle 30. A wind shield 29 is arranged between the two nuts 301. The spray head is located in the wind shield 29. The nuts 301 outside the wind shield 29 are fixed in the hexagonal slot 270 and are fixed to each other by a radial screw.

[0067] The number of nuts 301 is not limited to two. The reason for arranging two nuts 301 is mainly to fix the wind shield 29, and on the other hand, the two nuts 301 can cooperate with the hexagonal slot 270.

[0068] The first supporting rod 20 is connected to one end of a first pipeline 28. The other end of the first pipeline 28 passes around the first steering engine 24, the first fixed frame 25, the second steering engine 26 and the second fixed frame 27. The other end of the first pipeline 28 is connected to the output end of the spray head.

[0069] The spraying mechanism 2 is used to adapt to different spraying angles as follows:

[0070] Firstly, the first frame 23, the first steering engine 24 and the first fixed frame 25 are used in combination. The first frame 23 and the first fixed frame 25 are both "U" shaped structures, which realize the flipping of the spray head along the vertical direction. Secondly, the second fixed frame 27 and the second steering engine 26 are used in combination, which realize the swinging of the spray head along the horizontal direction.

[0071] Finally, they work together to ensure that the spray head can adapt to different heights and multi-angle spraying requirements in horizontal and vertical directions, and ensure that the spray head can rotate flexibly to cover a wider spraying area.

[0072] This double-rudder controlled spray head not only improves the precision and efficiency of spraying, but also greatly enhances the flexibility and adaptability of insulation spraying operations.

[0073] Embodiment two

[0074] Participation Figures 5-6 This embodiment is based on embodiment one and claims a UAV spraying device, which includes a UAV body 1, a spraying mechanism 2, a radar support 40, a radar body 4, and a spraying pump body 5.

[0075] The UAV body 1 is a kind of unmanned aerial vehicle controlled by wireless remote control equipment or self-provided program control device, which is prior art and will not be described again; the UAV body 1 includes a mounting frame 10 located at the bottom, the mounting frame 10 is connected with the spraying mechanism 2 at the rear side, and the spraying pump body 5 is arranged in the mounting frame 10.

[0076] The rear side of the mounting frame 10 is connected with a second fixed rod 102 through a second T-shaped block 101, the second fixed rod 102 is arranged horizontally, and the second fixed rod 102 is connected with a first support rod 20 through a cross fixed block 103 at the middle part; a second support rod 21 is connected with both sides of the mounting frame 10 through a T-shaped fixed block 104 respectively, wherein the position of the cross fixed block 103 is higher than that of the T-shaped fixed block 104.

[0077] At this time, first, by setting the length of the first support rod 20 to be 2 meters, the spray head can be fully away from the fan blades of the UAV body 1 in actual operation, effectively avoiding airflow interference and ensuring the stability of the spraying process. Secondly, the first support rod 20 and the second support rod 21 cooperatively constitute a stable triangular support structure to provide uniform and reliable support force for the spray head. Further, the cross fixed block 103 is used to fasten the end of the main support rod to the second fixed rod 102, which plays a key role in tensioning and positioning; at the same time, one end of the side support rod is connected with the rear side of the mounting frame 10 through the T-shaped fixed block, mainly bearing pressure load. The whole support system is reasonable in force and firm in connection, and the structural rigidity and stability are significantly improved.

[0078] The radar body 4 is installed at the bottom of the second fixed frame 27 through the radar support 40, and the radar body 4 is a device that emits electromagnetic waves. When the electromagnetic waves encounter a target object, they will be reflected. The radar body 4 receives and processes these reflected signals to obtain the distance, direction, height, speed, and other information of the target. It is prior art and will not be described again.

[0079] In fact, the radar body 4 can monitor the distance between the spray head and the spraying component in real time. When the spray head is too far or too close to the spraying component, the radar body 4 system will immediately send a signal to remind the operator to adjust the position through the unmanned aerial vehicle body 1 to ensure that the spray head always maintains the best spraying distance.

[0080] The spraying pump body 5 is used to transport and pressurize the paint to be sprayed uniformly on the surface of the object through the spraying mechanism 2. Specifically, the spraying pump body 5 includes a shell 50, a cartridge 51, a second pipeline (not shown in the figure), a plunger pump (not shown in the figure), a third pipeline (not shown in the figure), a fourth pipeline 52, a pneumatic hydraulic booster pump (not shown in the figure), a gas distribution reversing unit (not shown in the figure), a battery pin 53, a power switch 54, a backflow switch 55, and a gear adjustment 56. Two first fixed rods 105 parallel to each other are arranged at the bottom of the mounting frame 10, and the two ends of the first fixed rod 105 are connected to the mounting frame 10 through first T-shaped blocks 106.

[0081] The number of first fixed rods 105 is not limited to two. In fact, the more the number of first fixed rods 105, the more stable the installation of the spraying pump body 5. However, at the same time, the more materials are consumed, so the cost is comprehensive and the required installation stability of the spraying pump body 5 is determined.

[0082] The shell 50 is installed on the first fixed rod 105 through a pump body fixing block, wherein the pump body fixing block is a device for fixing the position of the pump body, usually made of metal or plastic, etc., has good wear resistance and corrosion resistance, and is a prior art, which will not be described here. The cartridge 51 is arranged at the top of the shell 50, and the paint is stored in the cartridge 51.

[0083] The plunger pump, the pneumatic hydraulic booster pump, and the gas distribution reversing unit are arranged in the shell 50. The lower end of the cartridge 51 is connected to the inlet of the plunger pump through the second pipeline, and the backflow port of the plunger pump is connected to the uppermost end of the cartridge 51 through the third pipeline. The plunger pump, as the main pressurizing unit, has a piston rigidly connected to the pneumatic hydraulic booster pump, which is responsible for periodically sucking paint and pressurizing it. The outlet of the plunger pump after pressurization is connected to the first support rod 20 through the fourth pipeline 52.

[0084] It is worth mentioning that when pouring paint into the cartridge 51, the liquid level should not exceed the upper backflow port, otherwise the backflow function will be disabled, causing equipment failure.

[0085] The plunger pump piston end is connected to the pneumatic hydraulic booster pump, which provides high-pressure power required for the reciprocating motion of the plunger pump piston. The pneumatic hydraulic booster pump is connected to the gas distribution reversing unit, which controls the on-off and direction of the gas path to command the pneumatic hydraulic booster pump and the entire system to work according to the predetermined program, realizing the automatic reversing and circulation of the plunger pump piston. It is a prior art and will not be described here.

[0086] The front side of the shell 50 is also provided with a battery pin 53, and the two sides of the shell 50 are also provided with a backflow switch 55, a power switch 54 and a gear adjustment 56. The battery pin 53 refers to the function and role of each pin on the battery interface, and is mainly used to power the entire spraying pump body 5. The power switch 54 is mainly used to start and stop the spraying pump body 5, and the gear adjustment 56 adjusts the spraying pressure, flow and other parameters to adapt to different spraying needs. The backflow switch 55 is used to control the path of the coating backflow, and is an essential part of the system to ensure stable pressure and coating circulation during spraying. The above are all prior art and will not be described in detail

[0087] The spraying pump body 5 is used for conveying and pressurizing the coating as follows:

[0088] First, the preparation work, specifically including;

[0089] Insert the battery pack into the battery pin 53 on the front side of the shell 50 to provide power for the entire system;

[0090] Make sure that the paint box 51 has been filled with enough paint, and the liquid level does not exceed the upper backflow port, so as to ensure the normal function of the backflow;

[0091] Turn on the power switch 54, the system circuit is connected, and the gear adjustment 56 knob or button is rotated according to the requirements of the current spraying task to preset the spraying pressure and flow parameters.

[0092] Second, the air path driving and pumping cycle process, specifically including:

[0093] The air distribution reversing unit starts to work, switching the direction of the compressed air channel;

[0094] The compressed air is guided to one side of the pneumatic hydraulic booster pump to drive the piston to move. The pneumatic hydraulic booster pump converts the low air pressure into high pressure hydraulic power;

[0095] The high pressure hydraulic power directly acts on the piston of the plunger pump to push it to do linear reciprocating motion;

[0096] Then, the coating is sucked and discharged, specifically including:

[0097] The coating is sucked, specifically, the piston of the plunger pump moves backward under the driving of the pneumatic hydraulic booster pump, the volume in the pump cavity increases, and negative pressure is generated;

[0098] Under the action of negative pressure, the paint in the paint box 51 is sucked into the pump cavity of the plunger pump through the first pipeline.

[0099] The coating is discharged, specifically, the air distribution reversing unit automatically reverses to drive the piston of the plunger pump to advance, and the volume of the pump cavity rapidly decreases;

[0100] The paint in the chamber is compressed violently, and the pressure rises rapidly, forming a high-pressure paint flow.

[0101] The high-pressure paint is sprayed from the outlet of the plunger pump after being pressurized and is introduced into the first support rod 20 through the fourth pipeline 52.

[0102] At this time, the first support rod 20 is in communication with the nozzle 30 through the first pipeline 28 to supply paint to the nozzle 30.

[0103] Embodiment Three

[0104] Referring to Figure 7 , the embodiment is based on embodiment two, and a UAV spraying method is claimed, which specifically comprises the following steps:

[0105] S1. The UAV body 1 is driven to hover at a first position; specifically, generally, it is only necessary to hover at a general position at this time.

[0106] S2. The measuring mechanism monitors the distance between the first position and the spraying component; specifically, the radar body 4 monitors the distance mainly to ensure that the distance between the first position and the spraying component is always at an optimal position suitable for spraying, and therefore, the radar body 4 can not only monitor the distance but also immediately send a signal to remind the operator to adjust the position through the UAV body 1 to ensure that the nozzle always remains at the optimal spraying distance when the nozzle is too far or too close to the spraying component.

[0107] S3. The UAV body 1 is driven to hover at a predetermined position based on the distance; specifically, the predetermined position generally refers to a position at which the nozzle is about 30 cm away from the spraying component, at which time the atomization effect of the fan-shaped spraying surface of the paint is optimal.

[0108] S4. The spraying pump body 5 is turned on, and the nozzle 30 performs a spraying operation on the spraying component; specifically, the spraying pump body 5 can be remotely controlled through a remote controller, for example, the spraying pump body 5 is turned on and off and adjusted to an appropriate gear for spraying.

[0109] S5. The multi-angle adjusting assembly is driven to adjust the different working angles and directions of the nozzle 30, which specifically comprises the following steps:

[0110] S50. When it is necessary to adjust the spraying angle in the vertical direction, the first rudder 24 is driven to drive the nozzle to flip in the vertical direction.

[0111] S51. When it is necessary to adjust the spraying angle in the horizontal direction, the second rudder 26 is driven to drive the nozzle to flip in the horizontal direction. Specifically, the adjustment of the first rudder 24 and the second rudder 26 can also be remotely controlled through a remote controller, which is prior art and will not be described in detail. It is worth mentioning that the details of each of the above steps have been disclosed in detail in the above description and will not be described in detail.

[0112] Moreover, throughout the process, through precise steering control and radar body 4 ranging, the spray head can uniformly and stably spray paint, avoiding paint waste and uneven spraying problems. On this basis, the design of the wind shield 29 also effectively reduces the influence of wind on the spraying effect, ensuring good spraying quality in various weather conditions.

[0113] In summary, the unmanned aerial vehicle insulation spraying method not only improves the safety and efficiency of power distribution network insulation reconstruction work, but also ensures the spraying quality and paint utilization rate through precise control and monitoring mechanism; therefore, it brings revolutionary changes to the insulation maintenance and reconstruction work of the power distribution network, and provides strong protection for the safe and stable operation of the power system.
