Description
Technical Field
[0001] This utility model relates to the field of fire fighting technology, and in particular to a fireproof ultrasonic fire extinguishing drone. Background Technology
[0002] Firefighting refers to the process of preventing, suppressing, and extinguishing fires through various means and technologies. Firefighting work is not only related to the safety of people's lives and property, but also an important part of public safety. Currently, common fire extinguishing equipment includes water-based fire extinguishers, dry powder fire extinguishers, carbon dioxide fire extinguishers, foam fire extinguishers, aerosol fire extinguishers, and ultrasonic fire extinguishers. In situations where traditional firefighting equipment is difficult to reach or cannot effectively respond, drones are also used to carry fire extinguishers. Currently, the Flame Sound drone is an innovative firefighting drone designed by Canadian designers Charles Bombadil and Adolf Eskiwell, which aims to improve public safety, especially the ability to respond to fires in forest and urban environments.
[0003] Currently, there are still some problems in the use of fire-resistant ultrasonic fire extinguishing drones. The fan position of the Flame Sound drone is fixed and cannot be adjusted according to flight requirements. This limits the drone's adaptability to different flight conditions. When rapid movement is required, the fixed fan position may not provide sufficient thrust and maneuverability. Furthermore, in urban firefighting, although glass curtain walls do not affect the ultrasonic waves from blowing away the oxygen from the fire source, they do affect the movement of the Flame Sound drone, thus affecting the progress of fire extinguishing. Therefore, those skilled in the art have provided fire-resistant ultrasonic fire extinguishing drones to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fireproof ultrasonic fire extinguishing drone. The drone uses a lifting structure to adjust the height of the base, thereby facilitating the switching between rapid and stable movement.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fireproof ultrasonic fire extinguishing drone, including a fuselage, a sliding groove is provided on the outer wall of the fuselage, a base is slidably connected inside the sliding groove, and a lifting structure is provided on the upper surface of the fuselage.
[0006] The lifting structure includes a base, which is fixedly connected to the upper end face of the machine body at the rear. A connecting rod is provided on one side of the base. A connecting groove is provided on the front end face of the connecting rod and on the side wall of the base. A first electric telescopic rod is rotatably connected between the two connecting grooves. A ring is provided on the upper end face of the machine body. The rear end of the connecting rod is fixedly connected to the center of the rear inner wall of the ring. An external gear is provided on the outer wall of the ring. Four lead screws are arranged in a rectangular pattern inside the slide groove. The upper ends of the four lead screws all penetrate the upper inner wall of the slide groove and extend to the upper end of the machine body. Each of the four lead screws is fixedly connected to a small gear. The four small gears mesh with the external gear.
[0007] The upper part of the body is provided with a protective cover. A first integrated control chip board is fixedly connected to the center of the upper part of the body. A first battery is fixedly connected to the upper part of the inner wall of the first integrated control chip board. A second electromagnet is fixedly connected to the center of the inner wall of the first integrated control chip board. A first electromagnet is provided at the lower end of the second electromagnet. A connection structure is fixedly connected to the lower end of the first electromagnet.
[0008] With the above technical solution, when rapid movement is required, the first electric telescopic rod is extended by controlling the first electric telescopic rod to push the connecting rod to one side. Since the ring is rotatably connected to the upper surface of the machine body, the ring is pushed to rotate. The ring drives the external gear to rotate, causing the four small gears to rotate, which in turn drives the four lead screws to rotate, causing the base to move downward along the slide groove, thus facilitating the switching between rapid and stable movement.
[0009] Furthermore, the connection structure includes a first connecting seat, a second connecting seat at the lower end of the first connecting seat, a first groove on the lower end surface of the first connecting seat, a second groove on the lower end surface of the second connecting seat, a first ball seat fixedly connected at the center of the inner wall of the first groove, at the four opposite corners of the inner wall of the first groove, at the center of the inner wall of the second connecting seat, and at the four opposite corners of the inner wall of the second connecting seat, a first ball rotatably connected at the center of the lower end surface of each of the ten first ball seats, a second electric telescopic rod fixedly connected at the center of the lower end surface of each of the ten first balls, a third ball fixedly connected at the other end of each of the ten second electric telescopic rods, a second ball seat sleeved on the lower part of the outer side wall of each of the ten third balls, and five second ball seats fixedly connected at the upper part to the center of the upper end surface of the second connecting seat and at the four opposite corners of the upper end surface of the second connecting seat respectively;
[0010] Through the above technical solution, the two second electric telescopic rods at the control center extend, the four second electric telescopic rods on one side retract, and the four second electric telescopic rods on the other side extend. The ten second electric telescopic rods rotate around the ten first and third spheres, causing the first and second connecting seats to move in an arc shape, tilting the vehicle body to the side, increasing the angle for fire extinguishing. Then, the four wall-climbing drive wheels attach the vehicle body to the glass curtain wall. The first and second electromagnets are de-energized and lose their magnetism, disconnecting from the body, which facilitates the extinguishing of fire sources at the rear of the glass curtain wall after separation, and also facilitates reconnection.
[0011] Furthermore, the lower end of the five second connecting seats is provided with a vehicle body, and the five second connecting seats are respectively fixedly connected to the center of the upper surface of the vehicle body and the four opposite corners of the upper surface of the vehicle body. The upper part of the vehicle body is fixedly connected to a second battery, the upper surface of the second battery is provided with a second integrated control chip board, and the lower part of the second battery is provided with an ultrasonic transmitter. The output end of the ultrasonic transmitter is fixedly connected to an output structure.
[0012] The above technical solution allows the second battery to provide power to the ultrasonic transmitter, the second integrated control chip board to provide remote control, and the ultrasonic transmitter to emit sound waves for fire extinguishing.
[0013] Furthermore, the output structure includes an output tube, and a spiral pattern is fixedly connected to the inner wall of the output tube;
[0014] Through the above technical solution, the sound waves are guided by the spiral pattern, which helps to concentrate and focus the sound waves, increase the energy density of the sound waves, and change the propagation direction of the sound waves, making them more concentrated in a specific area, thereby improving the accuracy of fire extinguishing.
[0015] Furthermore, climbing drive wheels are rotatably connected to the lower ends of both sides of the base.
[0016] The above technical solution provides power to the wall through four wall-climbing drive wheels and can attach the vehicle body to the glass curtain wall.
[0017] Furthermore, the upper surface of the base is provided with multiple mounting holes near the edge, each mounting hole is equipped with an electric turbine fan, and each electric turbine fan is provided with a dustproof net near the top.
[0018] The above technical solution uses multiple electric turbine fans for power and multiple dustproof nets to prevent damage to the multiple electric turbine fans from external objects.
[0019] This utility model has the following beneficial effects:
[0020] 1. In this utility model, when the fireproof ultrasonic fire extinguishing drone needs to move quickly, the first electric telescopic rod is extended by controlling the first electric telescopic rod to push the connecting rod to one side. Since the ring is rotated and connected to the upper surface of the fuselage, the ring is pushed to rotate. The ring drives the external gear to rotate, causing the four small gears to rotate, which in turn drives the four lead screws to rotate, causing the base to move downward along the slide groove, and causing multiple electric turbine fans to move downward. This can increase the stability of the drone on the roll axis, especially during high-speed flight or sharp turns. The low-profile wing design makes the drone perform better in terms of maneuverability.
[0021] 2. In this utility model, the vehicle body is tilted to the side by a connecting structure, and then the vehicle body is attached to the glass curtain wall by four wall-climbing drive wheels. The first electromagnet and the second electromagnet lose their magnetism when de-energized and disconnect from the body. Driven by the four wall-climbing drive wheels, the vehicle body is moved to the position where fire needs to be extinguished. The ultrasonic transmitter is activated, and the ultrasonic transmitter transmits 30 to 60 Hz sound waves through the glass curtain wall to blow away the oxygen on the fire source, thereby extinguishing the fire.
[0022] 3. In this utility model, the sound waves are guided by the spiral pattern, which helps to concentrate and focus the sound waves, improves the energy density of the sound waves, and changes the propagation direction of the sound waves, making them more concentrated in a specific area, thereby improving the accuracy of fire extinguishing.
[0023] 4. In this utility model, the two second electric telescopic rods at the control center extend, the four second electric telescopic rods on one side retract, and the four second electric telescopic rods on the other side extend. The ten second electric telescopic rods rotate around the ten first and third spheres, causing the first connecting seat and the second connecting seat to move in an arc shape, thus tilting the vehicle body to the side and increasing the angle for fire extinguishing. Then, the four wall-climbing drive wheels adsorb the vehicle body onto the glass curtain wall. The first and second electromagnets are de-energized and lose their magnetism, disconnecting from the body. This facilitates the extinguishing of fire sources at the rear of the glass curtain wall after separation and also facilitates reconnection. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0033] Reference Figure 1-6 An embodiment of this utility model is provided: a fireproof ultrasonic fire extinguishing drone, including a fuselage 1, a sliding groove 6 is provided on the outer side wall of the fuselage 1, a base 3 is slidably connected inside the sliding groove 6, and a lifting structure 2 is provided on the upper surface of the fuselage 1. The height of the base 3 can be adjusted by the lifting structure 2, so as to facilitate the switching between fast travel and stable travel.
[0034] The lifting structure 2 includes a base 201, which is fixedly connected to the upper end face of the body 1 at the rear. A connecting rod 203 is provided on one side of the base 201. A connecting groove 204 is provided on the front end face of the connecting rod 203 and the side wall of the base 201. A first electric telescopic rod 202 is rotatably connected between the two connecting grooves 204. A ring 205 is provided on the upper end face of the body 1. The rear end of the connecting rod 203 is fixedly connected to the center of the rear inner wall of the ring 205. An external gear 206 is provided on the outer wall of the ring 205. Four lead screws 208 are arranged in a rectangle inside the slide groove 6. The upper ends of the four lead screws 208 all penetrate the upper inner wall of the slide groove 6 and extend to the upper end of the body 1. A small gear 20 is fixedly connected to each end of the lead screws 208. 7. All four small gears 207 mesh with the external gear 206. When rapid movement is required, the first electric telescopic rod 202 is extended by controlling the first electric telescopic rod 202. The first electric telescopic rod 202 pushes the connecting rod 203 to one side. Since the ring 205 is rotatably connected to the upper end surface of the fuselage 1, the ring 205 is pushed to rotate. The ring 205 drives the external gear 206 to rotate, causing the four small gears 207 to rotate, which in turn drives the four lead screws 208 to rotate, causing the base 3 to move downward along the slide groove 6, and causing multiple electric turbine fans 15 to move downward. This can increase the stability of the UAV on the roll axis, especially during high-speed flight or sharp turns. The low-profile wing design makes the UAV perform better in terms of maneuverability.
[0035] A protective cover 4 is provided on the upper end of the body 1. A first integrated control chip board 10 is fixedly connected to the center of the upper surface of the body 1. The device inside the body 1 is controlled by the first integrated control chip board 10. A first battery 12 is fixedly connected to the upper part of the inner wall of the first integrated control chip board 10. The device inside the body 1 is powered by the first battery 12. A second electromagnet 14 is fixedly connected to the center of the upper inner wall of the first integrated control chip board 10. A first electromagnet 13 is provided at the lower end of the second electromagnet 14. A connection structure 11 is fixedly connected to the lower end of the first electromagnet 13. After the first electromagnet 13 and the second electromagnet 14 are energized, they magnetically attract each other, which facilitates the connection structure 11 to be connected and disconnected from the body 1.
[0036] like Figure 4 and 5As shown, the connecting structure 11 includes a first connecting seat 1101, a second connecting seat 1108 at the lower end of the first connecting seat 1101, a first groove 1102 on the lower end surface of the first connecting seat 1101, and a second groove 1109 on the lower end surface of the second connecting seat 1108. First ball seats 1103 are fixedly connected to the center of the inner wall of the first groove 1102, the four opposite corners of the inner wall of the first groove 1102, the center of the inner wall of the second connecting seat 1108, and the four opposite corners of the inner wall of the second connecting seat 1108. A first ball 1104 is rotatably connected to the center of the lower end surface of each of the ten first ball seats 1103. A second electric telescopic rod 1105 is fixedly connected to the center of the lower end surface of each of the ten first ball seats 1104. A third ball 1107 is fixedly connected to the other end of each of the ten second electric telescopic rods 1105. The lower part of the outer wall of each of the ten third balls 1107 is... A second ball seat 1106 is fitted on the upper part. Five second ball seats 1106 are fixedly connected to the center of the upper end face of the second connecting seat 1108 and the four diagonal points of the upper end face of the second connecting seat 1108. The two second electric telescopic rods 1105 at the control center position extend, four second electric telescopic rods 1105 on one side retract, and four second electric telescopic rods 1105 on the other side extend. The ten second electric telescopic rods 1105 rotate with ten first balls 1104 and third balls 1107, so that the first connecting seat 1101 and the second connecting seat 1108 move in an arc shape, so that the vehicle body 7 is tilted to the side, increasing the angle of fire extinguishing. Then, the vehicle body 7 is attracted to the glass curtain wall by four wall climbing drive wheels 8. The first electromagnet 13 and the second electromagnet 14 are de-energized and lose their magnetism, and are disconnected from the body 1, so as to facilitate the fire extinguishing of the fire source at the rear of the glass curtain wall after separation, and also facilitate reconnection.
[0037] like Figure 2 As shown, the lower end of the five second connecting seats 1108 is provided with the body 7. The five second connecting seats 1108 are fixedly connected to the center of the upper surface of the body 7 and the four diagonal points of the upper surface of the body 7. The upper part of the body 7 is fixedly connected with a second battery 18. The upper surface of the second battery 18 is provided with a second integrated control chip board 17. The lower part of the second battery 18 is provided with an ultrasonic transmitter 19. The output end of the ultrasonic transmitter 19 is fixedly connected with an output structure 9. The second battery 18 can provide power to the ultrasonic transmitter 19. The second integrated control chip board 17 can provide remote control, and the ultrasonic transmitter 19 emits sound waves to extinguish the fire.
[0038] like Figure 6 As shown, the output structure 9 includes an output tube 901, and a spiral pattern 902 is fixedly connected to the inner wall of the output tube 901. After the sound wave is guided by the spiral pattern 902, it helps to concentrate and focus the sound wave, and improve the energy density of the sound wave. The spiral pattern 902 changes the propagation direction of the sound wave, making it more concentrated in a specific area, thereby improving the accuracy of fire extinguishing.
[0039] The base 3 has climbing drive wheels 8 rotatably connected to the lower ends of both sides of the base 3. The four climbing drive wheels 8 provide power to the wall and can attach the vehicle body 7 to the glass curtain wall.
[0040] The upper surface of the base 3 is provided with multiple mounting holes 16 near the edge. Each mounting hole 16 is equipped with an electric turbine fan 15. Each electric turbine fan 15 is provided with a dustproof net 5 near the top. The multiple electric turbine fans 15 provide power, and the multiple dustproof nets 5 prevent foreign objects from damaging the multiple electric turbine fans 15.
[0041] Working principle: During use, when rapid movement is required, the first electric telescopic rod 202 is extended, pushing the connecting rod 203 to one side. Since the ring 205 is rotatably connected to the upper surface of the fuselage 1, it is pushed to rotate. The ring 205 drives the external gear 206 to rotate, causing the four small gears 207 to rotate, which in turn drives the four lead screws 208 to rotate, causing the base 3 to move downward along the slide 6. This causes the multiple electric turbine fans 15 to move downward, increasing the stability of the UAV on the roll axis, especially during high-speed flight or sharp turns. The low-profile wing design makes the UAV more maneuverable, suitable for tasks requiring rapid response and flexible operation. When stable firefighting is required, the first electric telescopic rod 202 is retracted, causing the ring 205 to rotate in the opposite direction, which in turn drives the four lead screws 208 to rotate in the opposite direction, causing the base 3 to move upward, so that the center of gravity of the UAV is located below the wing. This helps to improve the natural stability of the UAV, especially in low-speed flight or strong wind conditions.
[0042] When used in urban areas to extinguish fires near glass curtain walls, the two second electric telescopic rods 1105 at the control center extend, four second electric telescopic rods 1105 on one side retract, and four second electric telescopic rods 1105 on the other side extend. The ten second electric telescopic rods 1105 rotate around ten first spheres 1104 and third spheres 1107, causing the first connecting seat 1101 and second connecting seat 1108 to move in an arc shape, tilting the vehicle body 7 to its side. Then, four wall-climbing drive wheels 8 attach the vehicle body 7 to the glass curtain wall. The first electromagnet 13 and second electromagnet 14 are de-energized and lose their magnetism, disconnecting from the body 1. Driven by the four wall-climbing drive wheels 8, the vehicle moves to the location requiring fire extinguishing and activates the ultrasonic waves. The transmitter 19, an ultrasonic transmitter 19, transmits 30 to 60 Hz sound waves through the glass curtain wall to blow away the oxygen on the fire source, thereby extinguishing the fire. After the sound waves are guided by the spiral pattern 902, it helps to concentrate and focus the sound waves, increasing the energy density of the sound waves. The spiral pattern changes the direction of sound wave propagation, making it more concentrated in a specific area, thereby improving the accuracy of fire extinguishing. After the fire is extinguished, the first electromagnet 13 and the second electromagnet 14 are energized to generate magnetism, and the body 1 is moved to the top of the first electromagnet 13. The body 1 is then lowered, so that the first electromagnet 13 and the second electromagnet 14 stick together and attract each other. Then, the ten first electric telescopic rods 202 are retracted, and the body 7 is stored at the bottom of the body 1.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
