Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV nozzle pressurization device. Background Technology

[0002] With the rapid development of drone technology, its application in fields such as agricultural plant protection, environmental management, fire rescue, and public health is gradually expanding. In these applications, drones are equipped with spraying devices to complete liquid spraying tasks, such as pesticide spraying, water resource distribution, and fire extinguishing agent delivery.

[0003] Traditional pressurized spraying devices mostly use ground-based pressurization, delivering pressurized liquid to the nozzles via pipelines. While this method can provide high pressure, it limits the maneuverability and operating range of drones, especially in complex terrain or uninhabited areas. Furthermore, some existing drone spraying devices directly integrate traditional pressurization equipment, significantly increasing the overall weight of the equipment and affecting the drone's endurance and stability, thus limiting long-duration and large-scale operations. Therefore, we propose a drone nozzle pressurization device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Traditional pressurized spraying devices mostly use ground-based pressurization, delivering pressurized liquid to the nozzles through pipelines. While this method can provide significant pressure, it limits the maneuverability and operating range of drones, especially in complex terrain or uninhabited areas. Furthermore, some existing drone spraying devices directly integrate traditional pressurization equipment, resulting in a substantial increase in overall equipment weight, affecting the drone's endurance and stability, and limiting long-duration and large-scale operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drone nozzle pressurization device includes a drone body, a water tank is snapped onto the bottom of the drone body, a water pump is installed at the bottom of the water tank, water outlets A are provided at the four corners of the top of the water tank, water pipes A are connected to the water outlets A, one end of the water pipes A extends to a booster inside the drone body's arm, the other end of the water pipes A is connected to the water pump, and a nozzle is provided at the bottom of the top of the drone body's arm.

[0007] Furthermore, there are four superchargers, which are installed in the four arms of the drone body.

[0008] Furthermore, the outlet B of the booster is connected to a water pipe B, and the other end of the water pipe B is connected to a nozzle.

[0009] Furthermore, a liquid level sensor is installed on one side of the water tank, the sensing part of the liquid level sensor is inside the water tank, and the liquid level sensor is electrically connected to the main body of the drone.

[0010] Furthermore, several circular rings are symmetrically arranged at the top of the water tank, and hooks are provided at the bottom of the main chassis of the drone, with the circular rings connected to the hooks.

[0011] Furthermore, the nozzle is cylindrical, and several nozzles are evenly arranged on the bottom surface of the nozzle; the nozzle is a rotating nozzle.

[0012] Furthermore, an annular slide rail is installed at the bottom of the water tank, and the water pump is mounted on a slider on the annular slide rail. The water pump slides on the annular slide rail and is electrically connected to the drone.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The water tank in the device is equipped with a water pump and a booster inside the boom, with a dual pressurization design to ensure that the liquid can be delivered to the nozzle at a stable pressure, achieving efficient and uniform spraying operations. The boosters are distributed in the four booms to provide distributed pressure compensation, effectively reducing pipeline pressure loss and ensuring the stability and accuracy of spraying operations.

[0015] 2. The water tank adopts a snap-fit ​​and ring hook design, which makes installation and disassembly convenient. At the same time, the nozzle and water pump system are independent modules, which facilitates replacement and maintenance, thereby improving the service life and operating efficiency of the equipment.

[0028] Example 1

[0029] like Figure 1-4As shown, this utility model provides a technical solution: a drone nozzle pressurization device, including a drone body 1, a water tank 2 is snapped onto the bottom of the drone body 1, a water pump 203 is installed at the bottom of the water tank 2, the water pump 203 slides in the water tank 2, and water outlets A201 are provided at the four corners of the top of the water tank 2. Water pipes A202 are connected to the water outlets A201. One end of the water pipe A202 extends to a booster 101 inside the arm of the drone body 1. The booster 101 provides water pressure to ensure that the liquid can be delivered to the nozzle 102 at a stable pressure, so as to achieve efficient and uniform spraying operation. The other end of the water pipe A202 is connected to the water pump 203. A nozzle 102 is provided at the bottom of the top of the arm of the drone body 1. The nozzle 102 is a rotating nozzle, which increases the spraying area.

[0030] Example 2

[0031] like Figure 1-4 As shown, there are four boosters 101, which are installed in the four arms of the UAV body 1 respectively. The boosters 101 are distributed in the four arms to provide distributed pressure compensation and effectively reduce pipeline pressure loss. The outlet B104 of the booster 101 is connected to the water pipe B204. The other end of the water pipe B204 is connected to the nozzle 102. The nozzle 102 is cylindrical and has several nozzles evenly arranged on the bottom surface of the nozzle 102. The nozzle 102 is a rotating nozzle.

[0032] Furthermore, a ring-shaped slide rail 207 is installed at the bottom of the water tank 2. The water pump 203 is mounted on a slider on the ring-shaped slide rail 207, and slides on the ring-shaped slide rail 207. The water pump 203 is installed via the ring-shaped slide rail 207. The sliding design facilitates cleaning or replacement, significantly improving the maintenance efficiency of the equipment. The water pump 203 is electrically connected to the drone. The water pump 203 and the booster 101 achieve a dual pressurization design. This design ensures uniform spraying while reducing the energy consumption of the water pump 203. A liquid level sensor 205 is installed on one side of the water tank 2, and the sensing part of the liquid level sensor 205 is inside the water tank 2. The liquid level sensor 205 is electrically connected to the main body of the drone 1. The liquid level sensor 205 can monitor the remaining liquid in the water tank 2 in real time and feed the data back to the operator. The operator can adjust the operation path or add liquid according to the sensor data to avoid operation interruption and improve the continuity and efficiency of operation. Several rings 206 are symmetrically arranged on the top of the water tank 2. The bottom of the chassis of the drone main body 1 is equipped with a hook 103. The rings 206 are connected to the hooks 103. The water tank 2 is installed by snap-fitting the top rings 206 and the bottom hooks 103 of the drone main body. It is quick to install and remove, and convenient for adding liquid and cleaning the water tank 2.

[0033] The working process of this utility model is as follows: When using a drone nozzle pressurization device, firstly, remove the water tank 2 from the bottom of the drone, open the water inlet, add the required liquid (such as water, pesticide or fire extinguishing agent) to the water tank 2 to the appropriate level, then close the water inlet, and then fix the water tank 2 to the hook 103 on the chassis of the drone body 1 by the bottom ring 206. At the same time, ensure that the water pipe A202 is firmly connected to the booster 101 inside the drone body 1. Then check the connection between the nozzle 102 and the water pipe B204 to ensure that the nozzle 102 is firmly installed and the nozzle is unobstructed. Confirm that the power supply of the drone body 1 is working normally and that the water pump 203 is electrically connected to the control system normally.

[0034] The drone is started via remote control. Following a preset path or remote control commands, the drone flies to the spraying area, maintaining an appropriate altitude and speed. The drone control system activates water pump 203, which draws liquid from water tank 2. The liquid passes through water pipe A202, then through booster 101, and finally through water pipe B204 to nozzle 102. Nozzle 102 begins spraying. As the liquid passes through the rotating nozzle 102, it is evenly distributed on the nozzle and flows through the directional chip inside the nozzle 102 before being sprayed out through the orifices. Due to the nozzle design, the liquid generates inertia as it flows out. When the fluid leaves the nozzle 102, this inertia causes the liquid to maintain its speed and flow rate after exiting. This flow force propels the nozzle 102 to rotate. The rotation speed depends primarily on the water flow rate and pressure within the nozzle 102; therefore, increasing the fluid flow rate and pressure can accelerate the rotation speed of the nozzle 102.

[0035] The liquid level sensor 205 provides real-time feedback on the remaining liquid in the water tank 2. If the liquid is about to run out, the system will remind the operator. After reaching the end of the mission or when the liquid is exhausted, the spraying system will be turned off, the water pump 203 will be stopped, and the nozzle 102 will be kept free of residual liquid leakage. The drone will then be controlled to return to the starting position or the designated recovery point to ensure a safe landing.

[0036] Finally, disassemble water tank 2, empty the remaining liquid and clean the inside to ensure that no residual liquid remains, especially when changing the type of liquid (such as pesticide and water), to avoid contamination or blockage of nozzle 102. Check the condition of nozzle 102, pipeline and booster 101, remove blockages, and replace if necessary. Confirm that level sensor 205 and electrical connection components are working properly to ensure no faults in the next use.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
