The design of the caster wheel 102 allows for easy movement of the entire unit outdoors and convenient mounting on a drone; the weight reduction hole 103 is used to reduce the weight of the base frame 101 and reduce the load weight of the drone.

[0021] refer to Figure 1 , Figure 2 The mounting bracket 2 is mounted on the trolley assembly 1 and is used to provide mounting function. The mounting bracket 2 includes an outer frame 201 fixedly installed on the base frame 101, and a mounting frame 202 is fixedly connected to the middle of the outer frame 201. The outer frame 201 is used to provide protection for the internal components; the mounting frame 202 is used to mount and connect to the drone, and the mounting method can be hook type or lock type, which is convenient for installation and disassembly.

[0022] refer to Figure 1 , Figure 3 Liquid-containing assembly 3 is mounted on trolley assembly 1 and is used to provide extinguishing agent. Liquid-containing assembly 3 includes a water tank 301 fixedly mounted on base frame 101. Water tank 301 is equipped with water outlet pipe 302 and air inlet pipe 303. The top of water tank 301 is provided with an openable water filling end 304. The extinguishing agent is used to provide fire extinguishing function, such as using ordinary water; opening the water inlet 304 allows the extinguishing agent to be added into the water tank 301; the water outlet 302 is used to discharge the extinguishing agent; the air inlet 303 is used to balance the air pressure in the water tank 301 to ensure that the water tank 301 can meet the water supply requirements.

[0023] refer to Figure 1 Electrical component 4 is located on the trolley component 1 and is used to provide remote control functions; electrical component 4 includes a lithium battery, frequency converter, voltage regulator and controller; The lithium battery is used to provide power to the electrical device; the frequency converter and voltage regulator are used to ensure that the power supply is suitable for the use of the electrical device; the controller is used to provide control functions; since this device is mounted on a drone, it needs to have remote control functions. Therefore, the controller can integrate a remote control module, such as the remote control module commonly used in drones.

[0024] refer to Figure 1 , Figure 4 High-pressure component 5, mounted on trolley component 1, is used to generate high-pressure water flow. High-pressure component 5 includes a high-pressure water pump 501 fixedly mounted on base frame 101. The pumping end of the high-pressure water pump 501 is fixedly connected to a pumping pipe 502, and the outlet end of the high-pressure water pump 501 is fixedly connected to an outlet hose 503. The other end of the outlet hose 503 is fixedly connected to a spray bar 606, and a nozzle 607 is fixedly mounted on the end of the spray bar 606. The pumping pipe 502 is connected to the outlet pipe 302 of the water tank 301. When a high-pressure water flow is generated, the high-pressure water pump 501 operates, extracting the extinguishing agent, such as water, from the water tank 301 through the extraction pipe 502, and then delivering it to the spray bar 606 through the outlet hose 503. The water is then sprayed out at high pressure from the nozzle 607, enabling fire extinguishing operations and providing reaction force.

[0025] refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 9Energy storage component 6 is mounted on the bracket assembly 2 and is used to store potential energy. Energy storage component 6 includes an energy storage shell 601 fixedly mounted on the outer frame 201. An energy storage groove 602 is provided inside the energy storage shell 601. A movable slider 901 is slidably connected inside the energy storage groove 602. A mounting base 604 is fixedly connected to the upper part of the movable slider 901. An operating rod 6041 is fixedly connected to the outer side of the mounting base 604. An energy storage spring 603 is fixedly connected between the rear side of the movable slider 901 and the inner wall of the energy storage shell 601. A strength tube 605 is fixedly mounted inside the mounting base 604. A spray bar 606 is fixedly mounted inside the strength tube 605. During energy storage operation, the mounting base 604 is moved by the operating lever 6041, which in turn causes the movable slider 901 to slide in the energy storage groove 602. The movable slider 901 compresses the energy storage spring 603, which is compressed from its original length to a shorter length, thereby accumulating elastic potential energy.

[0026] refer to Figure 6 , Figure 10 , Figure 11 The crushing component 7 is located at the end of the energy storage component 6 and is used to provide a crushing surface. The crushing component 7 includes a crushing frame 701 fixedly installed at the end of the strength tube 605. A crushing ring 702 is fixedly connected to the outer end of the crushing frame 701, and a crushing tip 703 is fixedly connected to the outer end face of the crushing ring 702. When the accumulated elastic potential energy is released, it drives the crushing component 7 to move at high speed. It can be transmitted to the crushing tip 703 through the strength tube 605, the crushing frame 701, and the crushing ring 702. Then the crushing tip 703 can hit objects, such as glass, to achieve high-altitude glass breaking, create fire extinguishing windows, help to extinguish fires from different locations, and improve fire extinguishing efficiency.

[0027] refer to Figure 7 , Figure 8 , Figure 9 , Figure 10 The ranging component 8 is located inside the energy storage component 6 and is used to provide distance measurement function. The ranging component 8 includes an extension tube 801 fixedly installed on the movable slider 901, a protective plate 802 fixedly connected to the extension tube 801, a protective spring 803 fixedly connected to the protective plate 802, and an infrared distance sensor 804 fixedly installed inside the extension tube 801. The end face of the energy storage shell 601 is provided with a ranging hole 6011 for the extension tube 801 and the protective spring 803 to extend out. Since the movement distance of the crushing component 7 is limited, in order to maximize the crushing force, it is necessary to ensure that the distance between the crushing component 7 and the object to be crushed is appropriate. Therefore, the infrared distance sensor 804 can measure the distance from the object to be crushed to the infrared distance sensor 804 through the distance measuring hole 6011. Then, by subtracting the known length values ​​of the strength tube 605 and the crushing frame 701, the required value can be obtained, thereby ensuring that the crushing function can be realized smoothly. In addition, the ranging hole 6011 can be used for the extension tube 801 and the protective spring 803 to extend, so as to prevent the infrared distance sensor 804 from hitting the energy storage shell 601 and causing damage to the infrared distance sensor 804. At the same time, the design of the extension tube 801 and the protective spring 803 is used to provide protection for the infrared distance sensor 804 and also to prevent other objects from hitting the infrared distance sensor 804. The break-break function is typically used at windows where there is no dense smoke, ensuring that the drone can fly close to the window glass. After the window breaks, the drone quickly moves away to avoid smoke affecting its flight and to ensure the success of firefighting.

[0028] refer to Figure 7 , Figure 9 Release component 9, located within energy storage component 6, provides locking and releasing functions. Release component 9 includes a lifting cavity 904 within movable slider 901, a locking slide rod 903 slidably connected within lifting cavity 904, a locking spring 902 at the upper end of locking slide rod 903, a locking triangular block 906 fixedly connected to the lower end of locking slide rod 903, a fixed triangular block 905 on the left side of locking triangular block 906, and a sliding triangular block 908 on the right side of locking triangular block 906. A sliding groove 907 is provided within energy storage shell 601 corresponding to the sliding triangular block 908, and the sliding triangular block 908 slides in conjunction with the sliding groove 907. The fixed triangular block 905 is fixedly installed within energy storage shell 601. Under high water pressure reaction force, locking triangular block 906 can drive sliding triangular block 908 to slide and contact fixed triangular block 905, thereby releasing part of movable slider 901. The longitudinal cross-sectional shape of the fixed triangle block 905, the locking triangle block 906, and the sliding triangle block 908 are all right triangles; in order to ensure that the locking triangle block 906 can be released normally, the height of the sliding triangle block 908 is not lower than that of the fixed triangle block 905. When the locking function is activated, under the action of external force, the movement of the mounting base 604 and the movable slider 901 will drive the locking slide bar 903 and the locking triangular block 906 to move accordingly. When the locking triangular block 906 contacts the fixed triangular block 905, the inclined surface of the locking triangular block 906 and the inclined surface of the fixed triangular block 905 will contact each other, and the locking slide bar 903 and the locking triangular block 906 will move obliquely upward, generating an upward force, thereby overcoming the elastic force of the locking spring 902. The locking slide bar 903 and the locking triangular block 906 move upward. When the locking triangular block 906 moves to the gap between the fixed triangular block 905 and the sliding triangular block 908, under the action of the elastic force of the compressed locking spring 902, the locking slide bar 903 and the locking triangular block 906 will be driven downward. The locking triangular block 906 will directly engage with the gap between the fixed triangular block 905 and the sliding triangular block 908. Due to the obstruction of the fixed triangular block 905, the locking triangular block 906 cannot return to its original position, thereby realizing the locking function. In the locked state, the strength tube 605 and the spray bar 606 are partially retracted, which can prevent the rod-shaped parts from extending too far and affecting the flight attitude of the drone. Therefore, the drone flies more stably. If the sliding triangle block 908 and the fixed triangle block 905 are in contact with each other and there is no gap between them, the downward elastic force provided by the locking spring 902 can cause the lower tip of the locking triangle block 906 to be inserted between them, thus not affecting the normal implementation of the locking function. When the function is released, nozzle 607 opens clockwise. The clockwise high-pressure water flow from nozzle 607 generates a reaction force of 15-50 MPa, which is transmitted to the moving slider 901 via the spray bar 606, strength tube 605, and mounting base 604. This reaction force overcomes the elastic force of the energy storage spring 603, thus achieving a small-distance movement. The moving slider 901 drives the locking slide bar 903 and locking triangular block 906 towards the sliding triangular block 908. Because the inclined surface of locking triangular block 906 contacts the sliding triangular block 908, locking triangular block 906 overcomes the elastic force of locking spring 902 and moves upwards. After locking triangular block 906 passes the highest point of sliding triangular block 908, under the action of the elastic force of locking spring 902, the locking... The fixed triangular block 906 presses down on the inclined surface of the sliding triangular block 908. Then, under the elastic force of the energy storage spring 603, the moving slider 901, locking slide bar 903, locking triangular block 906 and locking triangular block 906 slide towards the fixed triangular block 905 in the sliding groove 907. Due to the obstruction of the fixed triangular block 905, the sliding triangular block 908 cannot continue to move. At this time, the locking triangular block 906 is higher than the fixed triangular block 905, and the fixed triangular block 905 cannot provide the locking function. The moving slider 901 and the mounting base 604 will move rapidly and release elastic potential energy, which can be transmitted to the crushing component 7 through the mounting base 604, strength tube 605 and spray bar 606 to provide the necessary impact force for the crushing function. The reaction force generated by the high-pressure water flow is 15-50 MPa. 1 MPa = 10 kgf / cm². Therefore, it can generate 150-500 kgf / cm². Thus, this reaction force is sufficient to drive the energy storage spring 603 to move. In addition, due to the compression and movement of the energy storage spring 603, the reaction force generated by the high-pressure water flow will be buffered. Therefore, the drone will fly more stably and will not crash due to excessive reaction force.

[0029] Working principle: The entire device is moved outdoors via casters 102; it is then mounted on a drone via mounting frame 202. When the locking function is activated, under the action of external force, the movement of the mounting base 604 and the movable slider 901 will drive the locking slide bar 903 and the locking triangular block 906 to move accordingly. When the locking triangular block 906 contacts the fixed triangular block 905, the inclined surface of the locking triangular block 906 and the inclined surface of the fixed triangular block 905 will contact each other, and the locking slide bar 903 and the locking triangular block 906 will move obliquely upward, generating an upward force, thereby overcoming the elastic force of the locking spring 902. The locking slide bar 903 and the locking triangular block 906 move upward. When the locking triangular block 906 moves to the gap between the fixed triangular block 905 and the sliding triangular block 908, under the action of the elastic force of the compressed locking spring 902, the locking slide bar 903 and the locking triangular block 906 will be driven downward. The locking triangular block 906 will directly engage with the gap between the fixed triangular block 905 and the sliding triangular block 908. Due to the obstruction of the fixed triangular block 905, the locking triangular block 906 cannot return to its original position, thereby realizing the locking function. In the locked state, the strength tube 605 and the spray bar 606 are partially retracted, which can prevent the rod-shaped parts from extending too far and affecting the flight attitude of the drone. Therefore, the drone flies more stably. Drones can be used to lift the entire device to a high altitude to carry out firefighting missions; Under normal circumstances, there is a good fire extinguishing window. At this time, the fire extinguishing action can be carried out directly. Specifically, the high-pressure water pump 501 works, and the fire extinguishing agent, such as water, is extracted from the water tank 301 through the liquid extraction pipe 502. Then, it is delivered to the spray bar 606 through the liquid outlet hose 503 and sprayed out at high pressure from the nozzle 607. Since the high-pressure water flow is continuously sprayed out, the reaction force of the high-pressure water flow is continuous, so the breaking function will not be triggered. When a high-rise building does not have good fire extinguishing windows, for example, the fire extinguishing position is blocked by glass, and water cannot directly enter the fire extinguishing point, the breaking function is used; Specifically, the infrared distance sensor 804 first measures the distance from the object to be broken to the infrared distance sensor 804 through the ranging hole 6011. Then, the known lengths of the strength tube 605 and the breaking frame 701 are subtracted to obtain the required value. This ensures that the breaking distance is appropriate. If the distance is not appropriate, the drone's flight position can be adjusted by controlling the remote control. Then, nozzle 607 opens and closes clockwise. The clockwise high-pressure water flow from nozzle 607 generates a reaction force of 15-50 MPa, which is transmitted to the moving slider 901 via the spray bar 606, strength tube 605, and mounting base 604. This reaction force overcomes the elastic force of the energy storage spring 603, thus achieving a small-distance movement. The moving slider 901 drives the locking rod 903 and locking triangular block 906 towards the sliding triangular block 908. Because the inclined surface of locking triangular block 906 contacts the sliding triangular block 908, locking triangular block 906 overcomes the elastic force of locking spring 902 and moves upwards. After locking triangular block 906 passes the highest point of sliding triangular block 908, it returns to its original position relative to the locking spring 902. Under the action of elastic force, the locking triangular block 906 will press down on the inclined surface of the sliding triangular block 908. Then, under the action of the elastic force of the energy storage spring 603, the moving slider 901, the locking slide bar 903, the locking triangular block 906 and the locking triangular block 906 slide towards the fixed triangular block 905 in the sliding groove 907. Due to the obstruction of the fixed triangular block 905, the sliding triangular block 908 cannot continue to move. At this time, the locking triangular block 906 is higher than the fixed triangular block 905, and the fixed triangular block 905 cannot provide the locking function. The moving slider 901 and the mounting base 604 will move quickly and release elastic potential energy, which can be transmitted to the crushing component 7 through the mounting base 604, the strength tube 605 and the spray bar 606. When the accumulated elastic potential energy is released, it drives the breaking component 7 to move at high speed. It can be transmitted to the breaking tip 703 through the strength tube 605, the breaking frame 701, and the breaking ring 702. Then the breaking tip 703 can hit the glass, which can break the glass at high altitude, create a fire extinguishing window, help to extinguish fire from different positions, and improve fire extinguishing efficiency. Therefore, this fire extinguishing device is very suitable for high-altitude fire extinguishing operations and can ensure the safety of people's lives and property.
