[0033] Example 1

[0034] See Figure 1 、 Figure 8 and Figure 9The present invention provides a drone-mounted fire extinguishing device. This device, mounted on a drone 200, allows for aerial firefighting operations, enabling rapid response to fire scenes and improving firefighting efficiency. In this embodiment, the mounted fire extinguishing device primarily comprises a tank 100 for storing fire extinguishing agent. This tank 100 is hollow and specifically designed to hold and store fire extinguishing agent. These fire extinguishing agents can be of various types, including but not limited to dry powder and water-based fire extinguishing agents. Furthermore, a feed port 110 is provided at the bottom of the tank 100. The primary function of this port 110 is to facilitate the loading and discharge of fire extinguishing agent. Through this port 110, the user can conveniently load fire extinguishing agent into the tank 100 or discharge it when needed for firefighting operations. This arrangement not only facilitates the replenishment and replacement of fire extinguishing agent but also ensures the efficient and convenient use of the fire extinguishing device. The tank 100 stores compressed gas and fire extinguishing agent, with different compressed gas pressures set for different fire extinguishing agents. For example, when using dry powder fire extinguishing agent, the pressure is set to 14-18 Pa. The release of compressed gas and fire extinguishing agent is controlled by opening and closing the valve. The principle is similar to that of existing fire extinguishers, but the difference lies in the control of the fire extinguishing agent spray.

[0035] See Figure 3 In the mounted fire extinguishing device, a valve seat 120 is provided at a specific position of the material port 110. This valve seat 120 is tightly connected to the material port 110, ensuring a smooth passage between the two. By using the valve seat 120 as a basic support point, a valve can be conveniently installed. This valve is configured to control the opening and closing state of the material port 110. When a fire extinguishing operation is required, the valve can be opened so that the fire extinguishing agent can be smoothly discharged from the material port 110, quickly and effectively extinguishing the fire source. The masking setting not only ensures the smooth discharge of the fire extinguishing agent, but also improves the efficiency and safety of the fire extinguishing operation.

[0036] The valve seat 120 is fixedly connected to the tank body 100. Specifically, the valve seat 120 is configured as a through-type structure, and a dedicated interface 121 is provided at its bottom. Through this interface 121, the valve is connected to the valve seat 120, ensuring connectivity between the two.

[0037] See Figure 2In the structure of the tank body 100, a bracket structure for supporting and fixing the tank body 100 is provided. The bracket structure consists of three main parts, namely a first bracket 130, a second bracket 140 and a third bracket 150. These brackets can not only effectively install and fix the tank body 100 to ensure its stability and safety, but also provide great convenience when manually lifting and placing the tank body 100. Through the setting of these brackets, operators can more easily carry out the transportation and installation of the tank body 100, thereby improving overall work efficiency and safety. The tank body 100 can also be installed on the drone 200 through the first bracket 130, the second bracket 140 and the third bracket 150.

[0038] In this embodiment, the first bracket 130 is configured to be installed at the top of the tank 100. This arrangement ensures that the first bracket 130 is securely fixed to the highest point of the tank 100, providing stable support for the entire structure. Furthermore, the second bracket 140 and the third bracket 150 are symmetrically arranged on both sides of the tank 100. This symmetrical layout not only helps maintain the balance of the entire system but also ensures that the second bracket 140 and the third bracket 150 evenly share weight and pressure during installation. To achieve connection with the drone 200, the tank 100 is installed using the first bracket 130 and / or the second bracket 140 and the third bracket 150 simultaneously. This installation method allows the drone 200 to be stably suspended below the tank 100, ensuring stability and safety during mission execution. The entire system not only has efficient firefighting capabilities but also exhibits excellent stability and reliability.

[0039] In this embodiment, the first bracket 130 is configured as a portable, easy-to-carry bracket. This portable bracket has a cylindrical structure, extending from the surface of the tank body 100 away from the tank body 100. To ensure the stability and practicality of the portable bracket, a number of through holes 131 are evenly distributed on its side. These through holes 131 not only provide the necessary fixing points during installation, but also serve as handles during actual use, making it easier for the operator to carry and move the tank body 100. This arrangement allows the operator to operate more conveniently, while also improving overall efficiency and safety.

[0040] See Figure 5, the second bracket 140 is configured as a block structure so that it can be firmly installed in the corresponding position. On the surface of the second bracket 140, there are multiple mounting holes 151 of different diameters. These mounting holes 151 are designed to be through-holes so as to penetrate from one side to the other. Furthermore, these mounting holes 151 can be configured as threaded mounting holes with threads. By inserting bolts into these threaded holes and tightening the bolts, it is possible to achieve firm fixation and installation with other components. In this way, the stability and reliability of the entire structure are significantly improved, and it is also convenient for subsequent disassembly and maintenance work. Through this arrangement, the connection between the various components is tighter, ensuring the stability and safety of the overall equipment during operation. The structural settings of the second bracket 140 and the third bracket 150 are consistent.

[0041] Furthermore, a mounting clip 152 is specifically provided on the side of the second bracket 140 facing away from the tank 100 to facilitate quick installation, positioning, and connection with other mounting structures. The second bracket 140 and third bracket 150 are attached to the side of the tank 100 to ensure the stability and reliability of the overall structure. This arrangement allows for quick and easy connection between the second bracket 140 and other components, improving overall device installation efficiency.

[0042] For further information, see Figure 3 , a threaded bayonet 122 structure is provided on the inner wall of the interface 121. The main function of these threaded bayonet 122 is to clamp and install the valve, ensuring that it can be smoothly connected to the interface 121 and communicated. Through this clamping method, the valve can be firmly fixed on the interface 121, thereby ensuring that it has sufficient stability during the output of the fire extinguishing agent. In this way, the valve will not fall off due to external force or vibration, thereby ensuring the safety and reliability of the entire system. Through this design, we can effectively prevent the valve from accidentally falling off the tank body 100 when the fire extinguishing agent is output, thereby avoiding potential safety hazards and ensuring the stable operation of the fire extinguishing device.

[0043] For further information, see Figure 4 The valve is a pilot-operated container valve 160, equipped with several key components to ensure its efficient operation. Specifically, the pilot-operated container valve 160 is equipped with two valve ports: a first valve port 161 and a second valve port 162. The primary function of these two valve ports is to connect to other related components, thereby ensuring the smooth operation of the entire system. In addition, the valve is equipped with an electric actuator 163 (switch) for remote control of the valve's opening and closing.

[0044] An electrical connection is established between the electric starter 163 and the drone 200, enabling direct control of the valve from the drone 200. This arrangement allows the drone 200 to achieve greater flexibility and efficiency in firefighting operations. The drone 200's onboard power supply provides the required power to the electric starter 163, enabling remote control of the valve. This firefighting system enables the drone 200 to quickly respond to fire scenes and effectively extinguish fires by precisely controlling the opening and closing of valves, significantly improving firefighting efficiency and safety.

[0045] See Figure 3 The first valve port 161 is configured as an embedded structure, disposed inside the threaded bayonet 122, and forms a firm and stable fixed connection with the threaded bayonet 122. Thus, the tank body 100 can achieve connectivity with the threaded bayonet 122 through the connection between the first valve port 161 and the threaded bayonet 122, thereby ensuring smooth operation of the entire system.

[0046] See Figure 3 and Figure 6 , a connector assembly is also provided at the second valve port 162 of the pilot-operated container valve 160. This connector assembly consists of several key parts, including a male straight connector with an external thread, a female quick-connect male connector 172 and a female quick-connect female connector 173. These components are arranged in a precise order and tightly connected to ensure the smooth operation and efficient connection of the entire system. The male straight connector with an external thread serves as the starting part of the connector assembly and is responsible for connecting with the second valve port 162 to ensure sealing and stability. Then, the female quick-connect male connector 172 and the female quick-connect female connector 173 are connected in sequence to form a quick-plug interface 121, making the connection of the entire system more convenient and reliable. This design not only improves the convenience of operation, but also ensures the sealing and safety of the system.

[0047] The connector assembly is tightly connected to the second valve port 162 via its internal male-female straight connector 171. This connection ensures a stable and tight connection, thus ensuring reliable operation of the entire system. The design of the male-female straight connector 171 makes the connection process simpler and faster, while also improving the strength and durability of the connection.

[0048] At the other end of the connector assembly, one end of the female quick-connect female connector 173 is tightly connected to the female quick-connect male connector 172. This quick-connect arrangement makes the connection and removal process very convenient, greatly improving work efficiency. The other end of the female quick-connect female connector 173 is configured as a spray gun connection port 174, which allows the user to directly connect the spray gun 310 to the fire extinguishing system. The setting of the spray gun connection port 174 takes into account the operator's convenience of use, ensuring a quick and stable connection, while also ensuring the stability and safety of the spray gun 310 during use.

[0049] See Figure 2 and Figure 7 In this embodiment, a safety diaphragm bolt 164 and a pressure gauge 165 are respectively provided on either side of the pilot-operated container valve 160. Specifically, safety diaphragm bolt 164 is located on one side of the pilot-operated container valve 160, while pressure gauge 165 is located on the other side. This arrangement ensures that both safety diaphragm bolt 164 and pressure gauge 165 can effectively function during operation.

[0050] In addition, the pressure gauge 165 is connected to the pilot-operated container valve 160 through a specific opening 166. This opening 166 can serve as both an inflation port and a port for the pressure gauge 165. This design enables the pressure gauge 165 to accurately measure the pressure within the container, and when necessary, inflation or deflation operations can be performed through this opening 166.

[0051] To further ensure operational convenience and safety, the opening 166 is also equipped with an inflation / deflation nut 167. This inflation / deflation nut 167 can be easily tightened or loosened, thereby controlling the pressure within the container. This direct injection allows the operator to easily perform inflation or deflation operations while ensuring the sealing and safety of the entire system. The pilot-operated container valve 160 of this embodiment utilizes a safety diaphragm bolt 164 and a pressure gauge 165 on either side, and connects the pressure gauge 165 via an opening 166 that serves as both an inflation port and a pressure gauge 165 port. Furthermore, the inflation / deflation nut 167 allows for precise measurement and control of the pressure within the container, ensuring operational convenience and safety.

[0052] Example 2

[0053] See Figure 8 and Figure 9The present invention provides a mounting bracket for a fire-extinguishing device mounted on a drone. In this embodiment, the mounting bracket 300 consists of two main parts: a first mounting portion and a second mounting portion. Each of these mounting portions is equipped with at least two legs, one end of which is connected and secured by a connecting rod. The other end of these legs, i.e., the end without the connecting rod, is specifically used for mounting and connecting to the drone 200.

[0054] Furthermore, to enhance the stability and functionality of the mounting frame 300, the first and second mounting portions can be provided with additional mounting rods on adjacent sides of the connecting rod. These mounting rods are positioned on two adjacent legs of the first and second mounting portions. By attaching and coupling the first bracket 130 and the second bracket 140 of the tank body 100 to a mounting rod, the tank body 100 can be securely fixed to the mounting frame 300, thereby improving the stability and reliability of the overall structure.

[0055] Furthermore, to ensure the stability and safety of drone 200 upon landing, the connecting rod is designed and installed at the bottom of the legs, allowing it to directly contact the ground. When drone 200 needs to land during operation, the connecting rod will first contact the ground and provide the necessary support, thus ensuring the stability of drone 200 on the ground and preventing it from tilting or tipping, further improving the safety and reliability of drone 200 operation.

[0056] Example 3

[0057] See Figure 8 and Figure 9 The present invention provides a drone with fire-fighting capabilities. In this embodiment, the drone 200 includes the mounted fire-fighting device and mounting bracket 300 described in Examples 1 and 2. Specifically, a specialized structure is designed on the bottom of the drone 200 for mounting and securing the tank 100. Furthermore, corresponding structures are also provided around the bottom of the drone 200 for mounting and securing the mounting bracket 300. The mounting bracket 300 is securely fixed to the drone 200 through its own mounting structure, ensuring its stability and reliability.

[0058] Specifically, by connecting and installing the first bracket 130 of the tank 100 to the corresponding part of the drone 200, and simultaneously connecting and installing the second bracket 140 and the third bracket 150 to the two sides of the mounting frame 300, the tank 100 is securely fixed to the drone 200. This structural design not only ensures the stability of the tank 100, but also makes it less likely to shift or fall off during flight, thereby improving overall safety and reliability.

[0059] Also, see Figure 9 The spray gun connection port 174 is connected to the spray gun 310 through a connecting pipe; the spray gun 310 itself is fixed to the support leg of the mounting frame 300 through a fixed structure. This arrangement ensures that the spray gun 310 can maintain stable performance during fire extinguishing operations, thereby improving fire extinguishing efficiency and safety. The fixed structure of the spray gun 310 is designed to be both firm and flexible, and can adapt to different flight postures and environments during flight, ensuring that the spray gun 310 can always be accurately aimed at the fire source for effective fire extinguishing operations. It ensures the stability and reliability of the mounted fire extinguishing device and the mounting frame 300 on the drone 200, while also ensuring the stable performance of the spray gun 310 during fire extinguishing operations, thereby significantly improving fire extinguishing efficiency and safety.

[0060] For further information, see Figure 9 , the spray gun 310 is firmly fixed on the legs of the mounting bracket 300 according to a preset tilt angle. In this way, the position and angle of the spray gun 310 can be accurately adjusted according to actual needs to ensure that the spraying and fire extinguishing effects are optimal. The legs of the mounting bracket 300 are set very firmly and can withstand the various forces generated by the spray gun 310 during operation, thereby ensuring that the spray gun 310 will not be displaced or tilted during use, ensuring the uniformity and consistency of the spraying. In addition, this fixing method also makes it easy for the operator to adjust the angle of the spray gun 310 during the spraying operation to adapt to different fire extinguishing locations and improve the flexibility and efficiency of the operation. The direction of the spray gun 310 is a preset direction. When the direction of the spray gun 310 needs to be adjusted, it is controlled by operating the drone.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
