Description

[0003] At present, in the existing high-rise fire-fighting drone systems, tethered drones are mostly used to directly lift water pipes and the water in the water pipes. However, due to the limitation of the drone's load capacity, the quality of the water pipe line and the diameter of the water pipe are small, the water pipe's pressure bearing capacity is small, and the water supply capacity is small, resulting in a small amount of water sprayed during fire extinguishing and low nozzle pressure; when non-tethered drones are used, the water carrying capacity is small and the flight time is short, and the fire extinguishing effect cannot be effectively achieved. In addition, the water pipes on the drones in the existing technology can only spray water in one direction. When the fire is large or the location of the fire is relatively unique, the water spray direction cannot be adjusted according to the actual situation or water cannot be sprayed from multiple different directions, resulting in poor fire extinguishing effect.

[0039] In another example, the tethered power supply component 12 may include an optoelectronic composite cable, which may be electrically connected to the tethered drone 2 to transmit signals to the tethered drone 2 via the optoelectronic composite cable.

[0040] As another example, the water pump assembly 13 may include parts such as a water tank and a water pump. The water supply pipe 4 may be connected to the water tank, and the water supply pipe 4 may be connected to the water pump.

[0041] In the above embodiment, since a tethered power supply component 12 is provided, the tethered power supply component 12 can transmit a signal to the tethered drone 2, thereby ensuring stability during the fire extinguishing process and improving the continuity of the fire extinguishing work. Since a water pump component 13 is provided, the water pump component 13 can continuously deliver water flow on the one hand, and on the other hand, it can increase the water outlet pressure of the water supply pipe 4, thereby improving the fire extinguishing effect. Since a telescopic component 15 is provided, the water supply pipe 4 can be delivered to a specified height through the telescopic component 15, so as to facilitate the treatment of fires at different locations.

[0042] In some embodiments of the present application, Figure 1 As shown, the telescopic assembly 15 includes a plurality of lifting arms 152, and the support assembly 11 is hinged with a first cylinder 151, wherein one of the lifting arms 152 is rotatably connected to the support assembly 11, and the output end of the first cylinder 151 is hinged with the lifting arm 152; the plurality of lifting arms 152 are connected end to end, and the end of the lifting arm 152 away from the support assembly 11 is hinged with a second cylinder 153, and the output end of the second cylinder 153 is hinged with the adjacent lifting arm 152; the water supply pipe 4 is connected to the lifting arm 152, and the water supply pipe 4 or the lifting arm 152 is connected with an optoelectronic composite cable, one end of the optoelectronic composite cable is connected to the tethered power supply assembly 12, and the other end is connected to the tethered drone 2.

[0050] In the above embodiment, since the console 14 is provided, the console 14 is provided to facilitate the operation of the staff, thereby reducing the labor intensity of the staff and improving the work efficiency.

[0051] In some embodiments of the present application, reference Figure 2 and Figure 3 , Figure 2 shows a structural diagram of the switching mechanism 3, Figure 3The structure diagram of the conversion box 301 is shown. The switching mechanism 3 includes a conversion box 301, which is installed at a corresponding position on the tethered drone 2, and the water supply pipe 4 is connected to the conversion box 301. The conversion box 301 is provided with a plurality of water outlets 302, and the water outlets 302 are connected to the water outlet pipes 303; a switching component is installed in the conversion box 301, and the liquid in the conversion box 301 is sprayed out through different water outlet pipes 303 through the switching component.

[0052] Exemplarily, the switching mechanism 3 can be configured to include a conversion box 301, and the conversion box 301 can be installed at a corresponding position on the tethered drone 2. For example, the conversion box 301 can be installed at a middle position of the tethered drone 2 without affecting the water in the conversion box 301 from being sprayed from the conversion box 301 to the fire location.

[0053] In another example, the water supply pipe 4 can be connected to the conversion box 301, and the conversion box 301 can be provided with a plurality of water outlets 302. For example, the number of the water outlets 302 can be four, and the four water outlets 302 can be arranged in four directions of the conversion box 301. The four water outlets 302 can all be connected to the water outlet pipe 303. The water supply pipe 4 transports water to the conversion box 301, and the water in the conversion box 301 is sprayed out through the water outlet pipe 303. The number of the water outlets 302 is not specifically limited in the embodiment of the present application.

[0054] Another example, see Figure 4 and Figure 5 , Figure 4 shows a switching component structure diagram, Figure 5 The schematic diagram of the structure of the connecting member 308 and the connecting groove 310 is shown. A switching assembly can be installed in the conversion box 301, and the switching assembly can be set to a structural form including a motor 304. The motor 304 can be installed on the inner bottom surface of the conversion box 301. The output shaft of the motor 304 can be fixed with a first connecting rod 305. Both ends of the first connecting rod 305 are connected to a first blocking member 306. The first blocking member 306 can be a first baffle. The first baffle is provided with a first opening 307. The size of the first opening 307 can match the size of the corresponding water outlet 302.

[0055] The output shaft of the motor 304 may be equipped with a connector 308, which may be disposed between the first connecting rod 305 and the inner bottom surface of the conversion box 301, and the connector 308 may be a spline. The output shaft of the motor 304 may be sleeved with a second connecting rod 309, and both ends of the second connecting rod 309 may be provided with a second blocking member 311, which may be a second baffle, and the second baffle is provided with a second opening 312, and the size of the second opening 312 may match the size of the corresponding water outlet 302.

[0056] Furthermore, the second connecting rod 309 can move along the axis direction of the output shaft of the motor 304 on the output shaft of the motor 304. The second connecting rod 309 is provided with a connecting groove 310. Taking the connecting member 308 as a spline as an example, the size of the connecting groove 310 can match the size of the spline, and the shape of the connecting groove 310 can match the shape of the spline. Under the driving force, the second connecting rod 309 can be connected to the output shaft of the motor 304 through the connecting groove 310 and the spline, so that the rotation of the output shaft of the motor 304 drives the second connecting rod 309 to rotate.

[0057] In another example, a sensor assembly 5 may be provided on the inner bottom surface of the conversion box 301. For example, the sensor assembly 5 may include a sensor and a driver, etc. The output end of the driver may be connected to a support plate 6, which is provided between the second connecting rod 309 and the inner bottom surface of the conversion box 301. When the sensor detects that the surrounding smoke concentration or temperature and other indicators are higher than the set standard, the sensor transmits a signal to the driver, and the driver provides a driving force to the support plate 6, pushing the support plate 6 to move in a direction away from the inner bottom surface of the conversion box 301, so that the connection groove 310 and the connecting member 308 are engaged.

[0058] It should be explained that a protective shell 7 can be installed on the bottom surface of the conversion box 301, and the motor 304 and the sensor assembly 5 can be installed in the protective shell 7. The protective shell 7 provides protection for the motor 304 and the sensor assembly 5, thereby reducing the probability of failure of the motor 304 and / or the sensor assembly 5 due to water ingress.

[0059] In the above embodiment, due to the first connecting rod 305, the first blocking member 306 and the first opening 307, one or two water outlets 302 on the conversion box 301 can be controlled to open; due to the second connecting rod 309, the second blocking member 311 and the second opening 312, three or four water outlets 302 on the conversion box 301 can be controlled to open; due to the sensor assembly 5, the support plate 6, the connecting member 308 and the connecting groove 310, the third and / or fourth opening can be automatically opened according to the actual situation. In this way, the water in the conversion box 301 can be sprayed out through different openings to deal with fires in different states and improve the fire extinguishing efficiency.

[0060] The following is an explanation of the use process of a fire-fighting drone system provided by this application. When in use:

[0061] S100: The fire-fighting drone system is moved to the location of the fire through the support mechanism 1, the first cylinder 151 is started, the first cylinder 151 pushes the corresponding lifting arm 152 to move, and the second cylinder 153 is started, the second cylinder 153 pushes the corresponding lifting arm 152 to move. By extending the lifting arm 152 and driving the tethered drone 2 through the corresponding equipment, the water delivery pipe 4 and the tethered drone 2 can enter the fire area.

[0062] S200: The water pump assembly 13 delivers water to the conversion box 301 through the water supply pipe 4. Under normal conditions, one of the first openings 307 on the first connecting rod 305 is aligned with the corresponding water outlet 302, and the other first opening 307 is staggered with the corresponding water outlet 302. The second opening 312 on the second connecting rod 309 is staggered with the corresponding water outlet 302, that is, only one water outlet 302 on the first conversion box 301 is open, and the water in the conversion box 301 is sprayed out through the water outlet 302 and the corresponding water outlet pipe 303. It can be understood that the conversion box 301 is similar to the role of a conversion joint. When the water in the water supply pipe 4 enters the conversion box 301 and then sprays out from the conversion box 301, the water pressure will not change, ensuring that the water sprayed from the conversion box 301 has a certain pressure.

[0063] S300: When the fire at the location of the tethered drone 2 becomes larger or there is a fire in other directions, the sensor assembly 5 is started, the sensor assembly 5 pushes the support plate 6 to move, and the support plate 6 pushes the second connecting rod 309 to move, so that the connecting groove 310 and the connecting member 308 are engaged. At the same time, the motor 304 is started, the output shaft of the motor 304 drives the first connecting rod 305 and the second connecting rod 309 to move, the first connecting rod 305 drives the first blocking member 306 to move, the first opening 307 on the first blocking member 306 is aligned with the corresponding water outlet 302, or the first blocking member 306 does not block the corresponding water outlet 302; the second connecting rod 309 drives the second blocking member 311 to move, the second opening 312 on the second blocking member 311 is aligned with the corresponding water outlet 302, or the second blocking member 311 does not block the corresponding water outlet 302. The water flow in the conversion box 301 can be controlled to spray from different water outlets 302 according to actual conditions, so as to handle fires at different locations or different degrees.
