Description

Technical Field

[0001] The present invention belongs to the field of drones, and more specifically relates to drone accessories. Background Art

[0002] In today's era of rapid technological development, drones have been widely used in many fields. In scenarios requiring liquid spraying, such as agricultural plant protection, environmental disinfection, and industrial spraying, drones are gradually becoming important operational tools due to their advantages of high efficiency and convenience.

[0003] However, when existing drones perform liquid spraying tasks, their nozzle structures have significant defects. The water outlet nozzles of current drones are usually fixed directly under the body, and the nozzle angle cannot be adjusted at all. This fixed nozzle layout makes the drone extremely poorly adaptable when facing different work sites and complex terrain. For example, when working in an orchard, the height, spacing and arrangement of fruit trees vary. It is difficult for fixed-angle nozzles to spray fruit trees in different positions comprehensively and accurately. Some areas are often under-sprayed, while others are over-sprayed. In farmland with large terrain undulations, the nozzle cannot adjust its angle according to changes in the terrain, resulting in the inability of the spray head to evenly cover the farmland, seriously affecting the work effect and resource utilization. When drones are used as a tool for removing pollution from photovoltaic panels, the above problems are even more prominent.

[0004] At the same time, existing drones generally have relatively few nozzles. This significantly limits the efficiency of drones, limiting the coverage area of ​​a single operation and requiring significant time and effort to complete large-scale spraying tasks. Furthermore, this insufficient number of nozzles directly impacts spraying effectiveness, making it difficult to achieve a uniform, fine spray, which can easily lead to uneven liquid distribution and fail to meet high-quality spraying requirements. This can lead to incomplete pest control in agricultural plant protection, incomplete comprehensive disinfection and sterilization in environmental pest control, and incomplete cleaning in the photovoltaic industry.

[0005] In summary, the shortcomings of the existing drone nozzle structure in terms of angle adjustment and the number of nozzles have seriously restricted the application effect and scope of drones in liquid spraying operations, and an innovative technical solution is urgently needed to improve it. Summary of the Invention

[0006] In view of the defects of the existing drone nozzles, the technical problem to be solved by the present invention is: based on the existing drone, a water spraying mechanism is designed to be used with the drone to solve the above problems.

[0007] To achieve the above-mentioned purpose, according to one aspect of the present invention, the present invention is implemented by the following technical measures: a water spraying mechanism for use with a supporting drone, comprising: A swing device, the swing device comprising a swing frame and a power device for driving the swing frame to swing back and forth, the swing frame being arranged below the frame of the UAV; A liquid storage tank is used to store liquid and is provided with a water outlet. An electric control valve is provided at the water outlet to control whether the water outlet is draining water; A soft nozzle, one end of which is connected to the water outlet and the other end of which is provided with a nozzle. The soft nozzle is movably fixed on a swing frame, and the water spraying angle of the nozzle is controlled by the swing of the swing frame; The water spraying mechanism is controlled by the drone main control board.

[0008] The water spraying mechanism described in the present invention cooperates with a liquid storage tank, a swing device, a soft nozzle and a nozzle. The liquid in the liquid storage tank is sprayed out from the nozzle through the soft nozzle. At the same time, the swing device is composed of a swing frame and a power device that drives the swing frame to swing back and forth. The swing frame is an extension frame of the drone. It is horizontal when taking off. When the drone flies to a certain height, it rotates to the lower end of the drone. In this way, the operator can adjust the angle of the swing frame according to needs, thereby controlling the angle of the nozzle on the swing frame, which can greatly improve the use effect.

[0009] Furthermore, the power device includes a cylinder and a pusher head, the pusher head is arranged on a swing frame, and the cylinder shaft of the cylinder is hingedly fixed to the pusher head. The above design increases the swing angle of the swing frame.

[0010] Furthermore, the power unit further comprises a cylinder base, to which the tail of the cylinder is hinged, so that both ends of the cylinder can swing up and down. The above design further increases the swing angle of the swing frame.

[0011] Furthermore, a plug-in interface is provided on the cylinder seat, and a clamping head is provided at the tail of the cylinder. The clamping head is clamped in the plug-in interface and is hingedly fixed by a pin shaft and a lock head that fixes the pin shaft.

[0012] Furthermore, the power unit further includes a slide rail and a slider. The slide rail is mounted on the drone frame. The slider is mounted on the slide rail and can slide back and forth. The slider is fixed by a locking member. The slider is fixed to the cylinder or the cylinder seat. This design facilitates the adaptation to drones of different sizes.

[0013] Furthermore, the locking member is composed of a locking block and a bolt. The locking block is in two pieces and is respectively arranged at both ends of the slider. The slider and the locking block are fixed by bolts, and the locking block can also move on the slide rail. At the same time, the locking block and the slide rail are also fixed by bolts.

[0014] Furthermore, the swing frame is composed of a frame body, a rotating rod and a fixed seat. There are two fixed seats, which are respectively arranged at both ends of the drone frame. The two fixed seats are provided with relative bearings. Both ends of the rotating rod pass through the bearings and are fixed to the frame body.

[0015] Furthermore, the frame is composed of two long rods, two short rods and a cross rod, the middle of the cross rod is movably fixed to the two long rods, and the two ends of the cross rod are movably fixed to the short rod.

[0016] Furthermore, the two long rods, the two short rods and the one crossbar are all foldable rods, and can be fixed to prevent folding after being unfolded. The above design is for easy storage.

[0017] Compared with the prior art, the advantages of the present invention are: 1. By adding a water spray mechanism to the UAV frame, the water spray mechanism cooperates with the liquid storage tank, the swing device, the soft nozzle and the nozzle. The liquid in the liquid storage tank is sprayed out from the nozzle through the soft nozzle. At the same time, the swing device is composed of a swing frame and a power device that drives the swing frame to swing back and forth. The swing frame is an extension frame of the UAV. It is horizontal when taking off. When the UAV flies to a certain height, it rotates to the lower end of the UAV. In this way, the operator can adjust the angle of the swing frame according to needs, thereby controlling the angle of the nozzle on the swing frame, which can greatly improve the use effect. 2. By designing the frame to consist of two long rods, two short rods and a horizontal rod, a nozzle can be fixed at the lower end of the two long rods and the two short rods to increase the spraying effect.

DETAILED DESCRIPTION

[0023] For descriptive purposes, this disclosure may use spatially relative terms, such as "below," "beneath," "beneath," "below," "above," "upper," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another component(s) as illustrated in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the drawings.

[0025] Figure 2 It is a schematic structural diagram of a power device according to one embodiment of the present disclosure.

[0026] Figure 3 Schematic diagram of the swing frame structure according to one embodiment of the present disclosure.

[0027] Figure 4 A schematic diagram of a frame structure according to an embodiment of the present disclosure.

[0028] Please refer to Figure 1 The present embodiment discloses a water spraying mechanism for use with a supporting drone, comprising: a swing device 1, a swing frame 2, a power device 3, a liquid storage tank 4, a soft nozzle 5 and a nozzle 20. The above-mentioned swing device 1 is composed of a swing frame 2 and a power device 3 that drives the swing frame 2 to swing back and forth. The swing frame 2 is fixed under the frame of the drone. The above-mentioned liquid storage tank 4 is used for storing liquid, and a water outlet is processed on the liquid storage tank 4. The water outlet is controlled by an electric control valve to control whether the water outlet is drained. The upper end of the above-mentioned soft nozzle 5 is connected to the water outlet, and the lower end is fixed with a nozzle 20. The soft nozzle 5 is movably fixed on the swing frame 2, and the water spraying angle of the nozzle 20 is controlled by the swing of the swing frame 2.

[0029] Combine Figure 2 and Figure 3Continuing to explain, the above-mentioned power device 3 includes a cylinder 6, a push head 7 and a cylinder seat 8. The above-mentioned push head 7 is fixed on the swing frame 2. The cylinder shaft of the cylinder 6 is hinged and fixed to the push head 7. The above-mentioned cylinder seat 8 is hinged for the tail of the cylinder 6 so that both ends of the cylinder 6 can swing up and down. At the same time, as a preferred structure, the above-mentioned cylinder seat 8 is provided with a plug interface 9, and a clamping head 10 is fixed to the tail of the cylinder 6. The clamping head 10 is clamped in the plug interface 9 and is hinged and fixed by a pin shaft and a lock head that fixes the pin shaft.

[0030] Of course, in order to facilitate the use of different drones, the position of the above-mentioned cylinder 6 needs to be designed to be adjustable. Therefore, on the basis of the above-mentioned structure, the above-mentioned power device 3 also needs to include a slide rail 11 and a slider 12. The two ends of the above-mentioned slide rail 11 are fixed on the frame of the drone. The slider 12 is stuck in the slide groove of the slide rail 11 and can slide back and forth, and is fixed by a locking member. The upper slider 12 is fixed to the cylinder 6 or the cylinder seat 8 (preferably the cylinder seat 8). The above-mentioned locking member is preferably composed of a locking block 13 and a bolt. The locking block 13 is two pieces, which are respectively arranged at both ends of the slider 12. The slider 12 and the locking block 13 are fixed by bolts, and the locking block 13 can also move on the slide rail 11. At the same time, the locking block 13 and the slide rail 11 are also fixed by bolts.

[0031] Continuing to explain, the above-mentioned swing frame 2 is composed of a frame body 14, a rotating rod 15 and a fixed seat 16. There are two fixed seats 16, which are respectively arranged at both ends of the UAV frame. The two fixed seats 16 are fixed with relative bearings near the lower side. Both ends of the rotating rod 15 pass through the bearings and are fixed to the frame body 14. The above-mentioned push head 7 is preferably fixed on the rotating rod 15. A lock that can be opened is designed on the side of the push head 7 fixed to the rotating rod 15. After the lock is buckled on the rotating rod 15, the notch of the lock is clamped by an arc-shaped locking plate. One side of the arc-shaped locking plate is hinged to the lock, and the other side is fixed by bolts. This technology is a common existing technology, so only a brief introduction is given.

[0032] Combine Figure 4 Continuing to explain, the above-mentioned frame 14 is composed of two long rods 17, two short rods 18 and a cross rod 19. The middle part of the above-mentioned cross rod 19 is movably fixed to the two long rods 17, and the two ends of the cross rod 19 are movably fixed to the short rods 18. Of course, such a frame 14 is not convenient when stored, so the above-mentioned two long rods 17, two short rods 18 and one cross rod 19 are all folding rods, and can be fixed to prevent folding after opening. Such folding rods are relatively common, so only the functions can be introduced.

[0033] When in use, the water spraying mechanism is controlled by the main control board of the UAV, and the swing frame 2 of the swing device 1 is placed horizontally in the initial state. When the UAV is launched, the cylinder 6 drives the rotating rod 15 to rotate, so that the frame 14 rotates downward to a vertical state, and the angle between the frame 14 and the UAV can be adjusted at any time according to needs, and the electric control valve is controlled to open, and the liquid in the liquid storage tank 4 will be sprayed out by the nozzle 20 through the soft nozzle 5. Of course, the lower ends of the two long rods 17 and the two short rods 18 are provided with nozzles 20, so that the spraying effect is most ideal. At the same time, the soft nozzle 5 needs to be connected to the four nozzles 20 through a four-way head.
