Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides the following technical solution:
[0023] Example 1
[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An adjustable pressure drone high-altitude cleaning fluid spraying mechanism includes a spraying mechanism and a support mechanism. The spraying mechanism is installed on the bottom of the drone for spraying cleaning fluid, and the support mechanism is installed on the bottom of the drone for cushioning and support.
[0025] The spraying mechanism includes a mounting frame 1, a liquid storage tank 2 fixedly connected to the mounting frame 1, a pump body 3 mounted on the mounting frame 1, a liquid extraction pipe 4 fixedly connected to the output end of the pump body 3, a drain pipe 5 fixedly connected to the output end of the pump body 3, a hose 6 fixedly connected to the end of the drain pipe 5 away from the pump body 3, a spray pipe 7 fixedly connected to the other end of the hose 6, multiple nozzles 8 fixedly connected to the right side of the spray pipe 7, an electric valve 9 mounted on the drain pipe 5, a pressure gauge 10 mounted on the drain pipe 5, and a telescopic assembly for adjusting the spray pipe 7 fixedly connected to the right side of the liquid storage tank 2.
[0026] The end of the liquid extraction pipe 4 away from the pump body 3 is fixedly connected to the liquid storage tank 2, and a transparent observation port is provided on the front of the liquid storage tank 2.
[0027] The telescopic assembly includes an outer rod 11 and a servo motor 12. A groove is provided on the outer rod 11, and a rack 13 is slidably arranged in the groove. A gear 14 is fixedly connected to the output end of the servo motor 12, and the rack 13 meshes with the gear 14.
[0028] One end of the rack 13 is fixedly connected to the spray pipe 7, and a mounting plate is fixedly connected to the right side of the liquid storage tank 2. The mounting plate is fixedly connected to the servo motor 12.
[0029] The left side of the outer rod 11 is fixedly connected to the liquid storage tank 2.
[0030] Through the above technical solution, the mounting frame 1 serves as the foundation of the entire spraying mechanism. The mounting frame 1 is fixed to the bottom of the drone, providing support for other components. The liquid storage tank 2 is fixed on the mounting frame 1 and is used to store cleaning fluid. A transparent observation port is provided on the front of the liquid storage tank 2, allowing operators to easily check the liquid level. The pump body 3 is mounted on the mounting frame 1 and connected to the liquid storage tank 2 via a suction pipe 4. When the pump body 3 is working, it draws cleaning fluid from the liquid storage tank 2 and delivers it to the spray pipe 7 through a drain pipe 5. One end of the drain pipe 5 is connected to the output end of the pump body 3, and the other end is connected to the spray pipe 7 via a flexible hose 6. The design of the flexible hose 6 allows the spray pipe 7 to move flexibly within a certain range. Multiple nozzles 8 are fixedly connected to the spray pipe 7 for evenly spraying the cleaning fluid onto the target area. An electric valve 9 and a pressure gauge 10 are installed on the drain pipe 5. Valve 9 controls the flow rate of the cleaning fluid, while pressure gauge 10 monitors the pressure in the drain pipe to ensure that the spraying pressure is within a safe range. A telescopic assembly is fixedly connected to the right side of the reservoir 2, including an outer rod 11, a servo motor 12, a rack 13, and a gear 14. The servo motor 12 drives the gear 14 to rotate, which in turn drives the rack 13 to slide in the groove of the outer rod 11, thereby realizing the telescopic adjustment of the spray pipe 7. When the drone needs to spray cleaning fluid, the pump body 3 starts, drawing the cleaning fluid from the reservoir 2 and delivering it to the spray pipe 7 through the drain pipe 5 and the hose 6. The electric valve 9 controls the flow rate of the cleaning fluid, and the pressure gauge 10 monitors the pressure in the drain pipe 5, providing real-time feedback to the control terminal for adjustment as needed. At the same time, the telescopic assembly can adjust the position of the spray pipe as needed to ensure that the cleaning fluid can be accurately sprayed onto the target area.
[0031] Example 2
[0032] Please see Figure 1 and Figure 4 Furthermore, based on Embodiment 1, the following is obtained: the support mechanism includes two support frames 15, each support frame 15 has a buffer plate 16 fixedly connected to its bottom, each buffer plate 16 has a set of spring shock absorbers 17 fixedly connected to its bottom, and each set of spring shock absorbers 17 has a base plate 18 fixedly connected to its bottom.
[0033] Each set of spring dampers 17 has four, and the two outermost spring dampers 17 are set at an angle.
[0034] Through the above technical solution, two support frames 15 are fixed on both sides of the bottom of the UAV to provide support for the entire support mechanism. Each support frame 15 is fixedly connected to a buffer plate 16 at its bottom to disperse the impact force when the UAV lands. Each buffer plate 16 is fixedly connected to a set of spring shock absorbers 17 at its bottom. The spring shock absorbers 17 absorb the vibration and impact generated when the UAV lands or performs a mission through their elastic deformation ability. Each set of spring shock absorbers 17 is fixedly connected to a base plate 18 at its bottom. The base plate 18 is in contact with the ground to ensure stable landing of the UAV. Each set of spring shock absorbers 17 is provided with four spring shock absorbers, and the two outermost spring shock absorbers 17 are set at an angle to improve the stability and shock absorption effect of the support mechanism, ensuring that the UAV can land and perform missions stably in various complex environments. When the UAV lands or performs a mission, the support mechanism first contacts the ground. The buffer plate 16 disperses the impact force, and the spring shock absorbers 17 absorb the vibration and impact through their elastic deformation ability. The angled spring shock absorbers can further improve the stability and shock absorption effect of the support mechanism, ensuring stable landing and mission performance of the UAV.
