Description

Technical Field

[0001] This utility model belongs to the field of drones, specifically drone accessories. Background Technology

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

[0003] However, existing drones have significant defects in their nozzle structure when performing liquid spraying tasks. Currently, the water nozzles of drones are typically fixed directly under the fuselage, and the nozzle angle is completely unadjustable. This fixed nozzle layout makes drones extremely unsuitable for different work sites and complex terrains. For example, in orchards, the height, spacing, and arrangement of fruit trees vary, and a fixed-angle nozzle cannot provide comprehensive and precise spraying to trees in different locations, often resulting in under-spraying in some areas and over-spraying in others. In farmland with significant terrain undulations, the inability of the nozzles to adjust their angle according to changes in terrain leads to uneven coverage of the pesticide, severely impacting operational efficiency and resource utilization. These problems are even more pronounced when drones are used as decontamination tools for solar panels.

[0004] Meanwhile, existing drones generally have a limited number of spray nozzles. This insufficient number of nozzles significantly restricts the drone's efficiency, limiting the coverage area per operation and requiring substantial time and effort to complete large-area spraying tasks. Furthermore, the insufficient number of nozzles directly impacts spraying effectiveness, making it difficult to achieve uniform and fine sprays, easily leading to uneven liquid distribution and failing to meet high-quality spraying requirements. In agricultural plant protection, this may result in incomplete pest and disease control; in environmental disinfection, it may prevent comprehensive and effective disinfection and sterilization; and in the photovoltaic panel industry, it may lead to incomplete cleaning.

[0005] In summary, the shortcomings of existing drone nozzle structures in terms of angle adjustment and the number of nozzles severely restrict the application effect and scope of drones in liquid spraying operations, and an innovative technical solution is urgently needed to improve them. Utility Model Content

[0006] In view of the defects of existing drone nozzles, the technical problem to be solved by this utility model is to design a water spraying mechanism for use with existing drones to solve the above problems.

[0007] To achieve the above objectives, according to one aspect of the present invention, the present invention is implemented through the following technical measures: a water spraying mechanism for use with a drone, comprising: The swing device consists of a swing frame and a power device that drives the swing frame to swing back and forth. The swing frame is located below the frame of the UAV. A liquid storage tank is used for storing liquid, and the liquid storage tank is provided with a water outlet. An electrically controlled valve is provided at the water outlet to control whether the water outlet drains. A flexible nozzle, one end of which is connected to a water outlet and the other end is equipped with a nozzle. The flexible nozzle is movably fixed on a swing frame, and the spray angle of the nozzle is controlled by the swing of the swing frame. The water spraying mechanism is controlled by the UAV main control board.

[0008] The water spraying mechanism described in this utility model utilizes a liquid storage tank, a swing device, a flexible spray pipe, and a nozzle. Liquid in the storage tank is sprayed out from the nozzle through the flexible spray pipe. The swing device consists 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, and when the drone flies to a certain height, the swing point is located at the lower end of the drone. This allows the operator to adjust the angle of the swing frame as needed, thereby controlling the angle of the nozzle on the swing frame, which greatly improves the usage effect.

[0009] Furthermore, the power unit includes a cylinder and a pusher head, the pusher head being mounted on the swing frame, and the cylinder shaft of the cylinder being hinged and fixed to the pusher head. This design increases the swing angle of the swing frame.

[0010] Furthermore, the power unit also includes a cylinder base, which is hinged to the tail of the cylinder, allowing both ends of the cylinder to swing up and down. This design further increases the swing angle of the swing frame.

[0011] Furthermore, the cylinder seat has a plug-in interface, and the tail of the cylinder is provided with a locking head. The locking head is locked in the plug-in interface and is hinged and fixed by a pin and a locking head that fixes the pin.

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

[0013] Furthermore, the locking component consists of a locking block and bolts. There are two locking blocks, which are respectively located at both ends of the slider. The slider and the locking blocks are fixed together by bolts, and the locking blocks can also move on the slide rail. At the same time, the locking blocks are also fixed to the slide rail by bolts.

[0014] Furthermore, the swing frame consists of a frame, a rotating rod, and a fixed base. There are two fixed bases, which are respectively located at both ends of the UAV frame. The two fixed bases are equipped with opposing bearings. Both ends of the rotating rod pass through the bearings and are fixed to the frame.

[0015] Furthermore, the frame consists of two long rods, two short rods, and a crossbar. The middle of the crossbar is movably fixed to the two long rods, and both ends of the crossbar are movably fixed to the short rods. This is to increase the number of nozzles.

[0016] Furthermore, the two long rods, two short rods, and one crossbar are all folding rods, and can be fixed in place to prevent folding when unfolded. This design facilitates storage.

[0017] Compared with the prior art, the advantages of this utility model are: 1. By adding a water spraying mechanism to the drone's frame, the water spraying mechanism uses a liquid storage tank, a swing device, a flexible nozzle, and a nozzle to spray liquid from the tank through the nozzle. The swing device consists of a swing frame and a power unit that drives the swing frame to swing back and forth. The swing frame is an extension of the drone. It is horizontal when taking off and rotates at the bottom of the drone after it reaches a certain height. This allows the operator to adjust the angle of the swing frame as needed, thereby controlling the angle of the nozzle on the swing frame, which greatly improves the performance. 2. By designing the frame to consist of two long poles, two short poles, and one crossbar, a nozzle can be fixed at the lower end of each of the two long poles and the two short poles to increase the spraying effect.

Detailed Implementation

[0023] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., as in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 3 This is a schematic diagram of a swing frame structure according to one embodiment of the present disclosure.

[0027] Figure 4 This is a schematic diagram of a frame structure according to one embodiment of the present disclosure.

[0028] Please refer to Figure 1 The water spraying mechanism disclosed in this embodiment for use with a drone includes: a swing device 1, a swing frame 2, a power unit 3, a liquid storage tank 4, a flexible spray pipe 5, and a nozzle 20. The swing device 1 consists of a swing frame 2 and a power unit 3 that drives the swing frame 2 to swing back and forth. The swing frame 2 is fixed below the frame of the drone. The liquid storage tank 4 is used to store liquid, and a water outlet is machined on the liquid storage tank 4. The water outlet is controlled by an electronically controlled valve to control whether the water outlet drains. The upper end of the flexible spray pipe 5 is connected to the water outlet, and the lower end is fixed with a nozzle 20. The flexible spray pipe 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] Combination Figure 2 and Figure 3 Continuing the explanation, the aforementioned power unit 3 includes a cylinder 6, a pusher 7, and a cylinder seat 8. The pusher 7 is fixed on the swing frame 2. The cylinder shaft of the cylinder 6 is hinged to the pusher 7. The cylinder seat 8 is used for hinged connection of the tail of the cylinder 6, so that both ends of the cylinder 6 can swing up and down. As a preferred structure, the cylinder seat 8 has an insertion interface 9. The tail of the cylinder 6 is fixed with a locking head 10. The locking head 10 is locked in the insertion interface 9 and is hinged and fixed by a pin and a locking head that fixes the pin.

[0030] Of course, in order to facilitate the use of different drones, the position of the cylinder 6 needs to be designed to be adjustable. Therefore, based on the above structure, the power device 3 also needs to include a slide rail 11 and a slider 12. The two ends of the 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. It 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 locking member is preferably composed of a locking block 13 and bolts. There are two locking blocks 13, which are respectively located at both ends of the slider 12. The slider 12 and the locking blocks 13 are fixed by bolts. The locking blocks 13 can also move on the slide rail 11. At the same time, the locking blocks 13 and the slide rail 11 are also fixed by bolts.

[0031] Continuing the explanation, the aforementioned swing frame 2 consists of a frame 14, a rotating rod 15, and a fixed base 16. There are two fixed bases 16, which are respectively located at both ends of the UAV frame. The two fixed bases 16 have opposing bearings fixed near their lower sides. Both ends of the rotating rod 15 pass through the bearings and are fixed to the frame 14. The aforementioned push head 7 is preferably fixed to the rotating rod 15. The side of the push head 7 fixed to the rotating rod 15 is designed with an openable locking slot. After the locking slot is fastened to the rotating rod 15, the notch of the locking slot is clamped by an arc-shaped locking piece. One side of the arc-shaped locking piece is hinged to the locking slot, and the other side is fixed by bolts. This technology is a common existing technology, so it will only be briefly introduced.

[0032] Combination Figure 4 Continuing the explanation, the aforementioned frame 14 consists of two long rods 17, two short rods 18, and one horizontal rod 19. The middle of the horizontal rod 19 is movably fixed to the two long rods 17, and both ends of the horizontal rod 19 are movably fixed to the short rods 18. Of course, such a frame 14 is not convenient to store. Therefore, the two long rods 17, two short rods 18, and one horizontal rod 19 are all folding rods, and they can be fixed to prevent folding after being opened. Such folding rods are quite common, so only their function can be described.

[0033] In use, the above-mentioned water spraying mechanism is controlled by the main control board of the drone. The swing frame 2 of the swing device 1 is initially placed horizontally. After the drone takes off, the cylinder 6 drives the rotating rod 15 to rotate, so that the frame 14 rotates downward to a vertical state. As needed, the angle between the frame 14 and the drone can be adjusted at any time, and the electronic control valve is opened. The liquid in the storage tank 4 will be sprayed out through the flexible spray pipe 5 and the nozzle 20. Of course, the lower ends of the two long rods 17 and the two short rods 18 are all equipped with nozzles 20, so that the spraying effect is the most ideal. At the same time, the flexible spray pipe 5 needs to be connected to the four nozzles 20 through a quarter head.
