Description

Technical Field

[0001] The invention relates to a drone-mounted spraying mechanism, belonging to the technical field of electric power aerial work equipment. Background Art

[0002] The external insulation performance of high-voltage transmission lines plays a vital role in their safe operation. Currently, various accidents frequently occur annually on high-voltage transmission lines due to contamination and coating shedding of anti-flashover paint, impacting power supply reliability. Traditionally, operations and maintenance personnel are required to monitor the operating status of the anti-flashover paint and organize and mobilize relevant personnel and equipment for construction and maintenance. However, these processes are often cumbersome and present challenges such as long construction periods, difficulty, high costs, and concerns about personal safety. If drones could be used to perform live spraying operations, this would significantly free up manpower and reduce operations and maintenance costs.

[0003] At present, most of the high-altitude cleaning and spraying of insulators are done manually. Not only are high-altitude operations dangerous, but the working environment is also harsh with high temperatures or severe cold. If drone-mounted equipment is used to replace manual work, it can reduce the personal safety risks of front-line operators, reduce the burden on front-line operators, and improve work efficiency. To this end, in the prior art, there is a utility model patent with Chinese patent authorization announcement number CN221024148U, which discloses an insulating paint spraying equipment mounted on a drone, including a drone body, two support frames are fixedly installed on the side of the drone body away from the spiral rod, and a bearing plate is fixedly installed between the two support frames by fasteners. A storage tank for storing insulating paint is fixedly installed on the side of the bearing plate away from the drone body, a discharge valve is provided on the side of the bearing plate away from the storage tank, and a spray gun body is provided on the side of the bearing plate away from the storage tank. The discharge valve is connected to the storage tank and the spray gun body respectively through pipe fittings, and an air tank is fixedly installed on the side of the bearing plate away from the drone body, and the air outlet of the air tank is connected to the air inlet end of the spray gun body through a high-pressure pipe. It installs the drone body and the carrier plate. During the flight of the drone body, the information collection device monitors the flight position, the insulating paint in the storage tank enters the spray gun body through the discharge valve, and the high-pressure gas in the gas tank enters the spray gun body. The high-pressure gas carries the insulating paint into the delivery pipe through the high-pressure pipe and is sprayed out from the nozzle. It has the advantages of reducing the work intensity of construction workers, realizing automatic high-altitude spraying function and improving spraying efficiency.

[0004] However, the above technical solution still has the following problems when used in practice: the delivery pipe is fixedly installed on two supporting blocks. As an important component of the spraying equipment, the delivery pipe needs to be inspected regularly. The fixed installation form will cause certain difficulties when the delivery pipe needs to be maintained or replaced, and there is a problem of inconvenience in maintenance and replacement.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 6This embodiment provides a drone-mounted spraying mechanism, comprising a drone base 1, provided with a base plate 2. The base plate 2 is secured to the drone base via a conventional clamp provided on its bottom. This clamp connection facilitates subsequent removal of the base plate 2 when necessary. A material storage box 3, a circulating pump 4, and a delivery pipe 5 are fixedly mounted on the top surface of the base plate 2. The material storage box 3 is filled with a suitable coating material. The delivery pipe 5 is provided with one end extending outside the base plate 2 to facilitate subsequent spraying operations. The discharge end of the material storage box 3 is connected to the feed end of the circulating pump 4 via a first hose 6, and the discharge end of the circulating pump 4 is connected to the delivery pipe 5 via a second hose 7. This allows the circulating pump 4 to transfer the coating material from the material storage box 3 to the delivery pipe 5 via the first hose 6 and the second hose 7 when the circulating pump 4 starts operating, for subsequent spraying operations.

[0025] In this embodiment, a quick-release card assembly 8 is further provided on the top surface of the base plate 2. The quick-release card assembly 8 is used to connect the delivery pipe 5 with the second hose 7. The quick-release card assembly 8 includes a quick-release card base 801, which is fixedly provided on the top surface of the base plate 2. The top surface of the quick-release card base 801 is provided with a groove 802. A clamping member 803 is provided in the groove 802. An end plate 804 is tightly clamped in the clamping member 803. The end of the second hose 7 proximal to the delivery pipe 5 is fixedly inserted through the end plate 804. The end of the second hose 7 passing through the end plate 804 is inserted into the corresponding side end of the delivery pipe 5. The position where the second hose 7 is connected to the delivery pipe 5 is fixed by providing a first American-style hose clamp 805. A quick-release card pressure plate 806 is also provided on the quick-release card base 801. The quick-release card pressure plate 806 clamps and connects the end of the delivery pipe 5 proximal to the second hose 7 to the quick-release card base 801.

[0026] Through the above-mentioned arrangement, the coordinated arrangement of the quick-release card base 801, the clamping member 803 and the end plate 804 can fix the end of the second hose 7 close to the delivery pipe 5 side, so that it can be fixed on the base plate 2, which is convenient for subsequent connection work. The first American-style hose clamp 805 in the quick-release card assembly 8 can connect the delivery pipe 5 with the second hose 7, and the quick-release card pressure plate 806 in the quick-release card assembly 8 can press the end portion connected to the delivery pipe 5 and the second hose 7 to the quick-release card assembly 8. Cooperating with the first American-style hose clamp 805, the connection strength between the delivery pipe 5 and the second hose 7 can be well ensured, making it less likely to fall off. When the delivery pipe 5 needs to be maintained or replaced, the connection between the delivery pipe 5 and the second hose 7 can be quickly released by removing the quick-release card pressure plate 806 and the first American-style hose clamp 805, and the delivery pipe 5 can be removed.

[0027] In this embodiment, a support frame 807 is provided on the side wall of the quick-release card base 801 proximal to the delivery tube 5. The orientation of the support frame 807 is aligned with that of the delivery tube 5, and the delivery tube 5 is positioned within the support frame 807. Furthermore, the support frame 807 and the delivery tube 5 are secured together by a first back-to-back Velcro 808. This arrangement provides support for the delivery tube 5, preventing it from breaking during the paint delivery process. The first back-to-back Velcro 808 secures the support frame 807 to the delivery tube 5, further ensuring that the delivery tube 5 is less likely to fall off.

[0028] In this embodiment, the support frame 807 is longer than the delivery pipe 5 to ensure that the support frame 807 can fully support the delivery pipe 5. A first extension tube 9 is provided at the end of the delivery pipe 5 away from the second hose 7. The first extension tube 9 is placed on the support frame 807 and is fastened to the support frame 807 by a second back-to-back Velcro 12. The second back-to-back Velcro 12 prevents the first extension tube 9 from falling off. The end of the first extension tube 9 proximal to the delivery pipe 5 is inserted into the corresponding end of the delivery pipe 5. The first extension tube 9 is fixed to the delivery pipe 5 by a second American-style hose clamp 10. The second American-style hose clamp 10 allows the first extension tube 9 to be detachably connected to the delivery pipe 5 to facilitate maintenance and replacement of the delivery pipe 5. At the same time, it also allows workers to replace the first extension tube 9 with an appropriate length according to actual needs to adapt to the spraying work. The end of the first extension tube 9 away from the conveying pipe 5 is arranged to extend out of the support frame 807 to facilitate the subsequent spraying work. A first nozzle 11 is provided on the end of the first extension tube 9 away from the conveying pipe 5. The first nozzle 11 is arranged in a fan-shaped structure to expand the spraying surface and ensure the spraying effect.

[0029] When using this embodiment, the staff first selects a delivery pipe 5 and a first extension pipe 9 of appropriate length, and installs them using a first American-style hose clamp 805, a quick-release clamping plate 806, and a second American-style hose clamp 10. After the installation is completed, the base plate 2 is mounted on the drone base 1, and then the drone can be started to start working, and the base plate 2 is lifted to the desired position. To facilitate the operation of the spraying mechanism, an electric control box component m for controlling the operation of the spraying mechanism and for transmitting information and executing instructions with the outside world can also be set on the base plate 2. The staff can control the operation of the spraying mechanism by issuing appropriate work commands to the electric control box component m. After the base plate 2 is lifted to the desired position, the staff adjusts the position of the spraying mechanism by controlling the drone so that the first nozzle 11 is aligned with the position where the high-voltage transmission line needs to be sprayed. After that, the staff issues a work command to the electrical control box component m to control the circulation pump 4 to start working. The circulation pump 4 can then transport the paint in the storage box 3 in sequence through the first hose 6, the second hose 7, the delivery pipe 5 and the first extension pipe 9, and finally spray it out from the first nozzle 11 to perform the required spraying work.

[0030] During the spraying process, the paint in the storage bin 3 decreases, causing the center of gravity of the spray mechanism to shift, which can affect the normal flight of the drone. Therefore, in this embodiment, a drive cylinder 26 is fixedly mounted on the bottom surface of the base plate 2. A counterweight plate 27 is mounted on the piston portion of the drive cylinder 26. The counterweight plate 27 is slidably connected to the bottom surface of the base plate 2. A weighing sensor for detecting the weight of the paint in the storage bin 3 is also mounted on the bottom wall of the storage bin 3. Furthermore, in this embodiment, the storage bin 3 is positioned on the left side of the base plate 2, while the drive cylinder 26 and the counterweight plate 27 are positioned on the right side of the base plate 2. Through the above-mentioned setting, when the paint in the storage box 3 becomes less, the weighing sensor can detect the change in the weight of the storage box 3, thereby generating an electrical signal and sending it to the electronic control box component m. After receiving the electrical signal, the electronic control box component m controls the driving cylinder 26 to start working, causing the driving cylinder 26 to push the counterweight plate 27 in the direction close to the storage box 3, thereby adjusting the center of gravity of the entire spraying mechanism to reduce the impact of the center of gravity change on the normal flight of the drone. The specific driving cylinder 26 pushing the counterweight plate 27 to move needs to be determined in combination with actual conditions, such as the center of gravity position of the drone and the center of gravity position of the base plate 2.

[0031] In order to further expand the spraying area of ​​the spraying mechanism and ensure that the paint can completely cover the required position of the high-voltage transmission line, embodiment 2 is proposed based on embodiment 1.

[0032] Example 2: Please refer to Figures 7-9This embodiment provides a UAV mounted spraying mechanism, which differs from the first embodiment in that the arrangement of the support frame 807 is different. Specifically, a first shell 13 is fixedly provided on the end of the support frame 807 away from the quick-release card base 801, and the end of the delivery pipe 5 close to the first shell 13 is connected to the first shell 13. The second shell 15 is rotatably connected in the first shell 13 by a rotating shaft 14. One side of the second shell 15 is connected to the end of the delivery pipe 5 close to the first shell 13 by a connecting hose 16, and a second extension pipe 17 is connected on the side wall of the other side. The end of the second extension pipe 17 away from the second shell 15 is arranged to pass through the first shell 13, and a second nozzle 18 is provided on the passing end of the second extension pipe 17. A rotating component for driving the second shell 15 to rotate in the first shell 13 is also provided on the first shell 13. A slide groove 19 is also provided on the first shell 13 to adapt the second extension pipe 17 to move with the second shell 15, and the second extension pipe 17 is slidably connected in the slide groove 19.

[0033] In this embodiment, the rotating assembly includes a third shell 20, which is fixedly arranged on the first shell 13. One end of the rotating shaft 14 is connected to the second shell 15, and the other end passes through the first shell 13 and movably passes into the third shell 20. A meshing gear 21 is provided on the shaft section of the rotating shaft 14 that passes through the third shell 20. A meshing tooth plate 22 is provided in the third shell 20, and the meshing tooth plate 22 is engaged with the meshing gear 21. A driving member for driving the meshing tooth plate 22 to perform horizontal reciprocating motion is also provided in the third shell 20.

[0034] In this embodiment, the driving member includes a reciprocating screw 23 horizontally arranged in the third shell 20, the reciprocating screw 23 is rotatably connected in the third shell 20, a reciprocating nut 24 is provided on the reciprocating screw 23, and the reciprocating nut 24 is fixedly connected to the meshing gear plate 22. A driving motor 25 is also provided on the outer wall of the third shell 20, and the electric spindle of the driving motor 25 extends into the third shell 20 and is fixedly connected to one side end of the reciprocating screw 23.

[0035] Through the above arrangement, when the drive motor 25 starts working, it can drive the reciprocating screw 23 to rotate in the third housing 20, so that the reciprocating nut 24 can make a corresponding reciprocating motion along the reciprocating screw 23, and then drive the meshing gear plate 22 to move accordingly. After the meshing gear plate 22 moves, it can drive the meshing gear 21 to rotate. According to the movement direction of the meshing gear plate 22, the meshing gear 21 will perform corresponding forward and reverse rotation, so that the second housing 15 can also perform corresponding forward and reverse rotation in the first housing 13, and then drive the second extension tube 17 to perform corresponding reciprocating swing along the slide 19. When the second housing 15 rotates forward and reverse, in order to adapt to the movement of the second housing 15, the connecting hose 16 can produce corresponding deformation.

[0036] When using this embodiment, the staff starts the work by starting the drone to lift the base plate 2 to the desired position. After the base plate 2 is lifted to the desired position, the staff adjusts the position of the spraying mechanism by controlling the drone so that the second nozzle 18 is aligned with the position where the high-voltage transmission line needs to be sprayed. After that, the staff issues a command to the electric control box assembly m, which controls the electric control box assembly m to control the circulation pump 4 and the drive motor 25 to start working. The circulation pump 4 can sequentially transport the paint in the storage box 3 through the first hose 6, the second hose 7, the delivery pipe 5 and the second extension pipe 17, and finally spray out from the second nozzle 18 to perform the required spraying work. After the drive motor 25 starts working, it can drive the second extension pipe 17 to swing back and forth to expand the coverage area of ​​the paint sprayed outward from the second nozzle 18, so as to ensure that the paint can completely cover the required position of the high-voltage transmission line.

[0037] To facilitate maintenance and replacement of the delivery pipe 5, a threaded sleeve 28 is fixedly mounted within the end of the connecting hose 16 proximal to the delivery pipe 5. The outer wall of the threaded sleeve 28 is positioned proximal to the inner wall of the connecting hose 16. The threaded sleeve 28 is positioned with one end extending out of the connecting hose 16. The inner wall of the end of the delivery pipe 5 proximal to the connecting hose 16 is provided with internal threads adapted for the threaded sleeve 28. The connecting hose 16 is connected to the delivery pipe 5 through the connection between the threaded sleeve 28 and the internal threads. This arrangement, combined with the threaded sleeve 28 and the internal threads, allows for a removable connection between the connecting hose 16 and the delivery pipe 5, facilitating maintenance and replacement of the delivery pipe 5.

[0038] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structures or equivalent process changes made using the contents of the present invention's description and drawings, or directly or indirectly applied to other related technical fields, are also included in the patent protection scope of the present invention.
