Description

Technical Field

[0001] The present invention relates to the field of high-altitude fire-fighting equipment, and in particular to an unmanned aerial vehicle (UAV) gimbal for high-altitude fire-fighting and an unmanned aerial vehicle (UAV) fire-fighting system. Background Art

[0002] The use of drones for high-rise firefighting has the advantages of flexible operation, fast speed, and the ability to reach designated locations without being restricted by geographical environments. It is an important means of firefighting. However, existing drone firefighting devices have the following disadvantages: (1) The drone is equipped with a water gun. When the water gun sprays water, it will cause the drone to fly unsteadily under the action of its reaction force, resulting in poor firefighting accuracy and low water utilization efficiency; (2) The practical behavior of using drones for fire rescue is generally to directly carry firefighting materials by drones, and then throw the firefighting materials to the fire scene after arriving at the designated location. Due to the small carrying capacity of drones, the amount of firefighting materials carried is limited, and the work efficiency is low. If multiple drones are used, multiple people are required to operate, which consumes a lot of manpower and material resources.

[0003] The invention patent application with publication number CN109316683A discloses a high-altitude fire-fighting device in which a fire-fighting water gun towed by a drone is connected with a fire-fighting water truck by using a fire hose. When the floor is high, the drone needs to withstand the gravity of a large water pipe and the water in the pipe, which puts high requirements on the load-bearing capacity of the drone, making the solution either very costly or only applicable to fire-fighting on medium and low floors. Summary of the invention

[0004] In view of a series of problems existing in the prior art of high-altitude firefighting by unmanned aerial vehicles, such as poor firefighting accuracy, small carrying capacity, and low firefighting efficiency, the present invention provides a high-altitude firefighting unmanned aerial vehicle gimbal, comprising a gimbal body and a water gun, wherein the water gun comprises a water gun body, a water gun head, and a water supply structure, wherein one end of the water gun body is horizontally mounted directly below the gimbal body, the water gun head is arranged at one end of the water gun body close to the gimbal body, the water supply structure is arranged on the lower surface of the water gun body, and the water supply structure is detachably connected to a water supply source; A main water inlet is provided on the lower surface of the water gun body near one end of the gimbal body, and an auxiliary water inlet is provided on the end away from the gimbal body. The water outlet of the water supply structure is connected with the main water inlet and the auxiliary water inlet. A first water flow cavity is formed inside the water gun body, and the first water flow cavity is connected with the water gun head and the main water inlet.

[0005] A main water inlet and an auxiliary water inlet are arranged on the lower surface of the water gun body. The auxiliary water inlet can offset the reaction force on the pan / tilt body caused by the water gun spraying changes, thereby playing a buffering role. It can also play a water replenishment role when the water flow is unstable or insufficient, thereby improving the stability of the water spray.

[0006] Preferably, the water supply structure comprises a water supply connector, one end of the water supply connector is provided with an auxiliary connector detachably connected to the auxiliary water inlet, and the other end is provided with a main connector detachably connected to the main water inlet, and the main connector and the auxiliary connector are connected through a hollow channel; The main connecting head is detachably connected to a water supply source just below the main connecting head.

[0007] A water supply connector is provided to distribute the water flowing into the main water inlet and the auxiliary water inlet.

[0009] Here, the external hose has a certain length and elasticity, and its volume can change after the water flow is passed into it, and the distance between the water flow from the auxiliary connection head to the water gun head is extended; more preferably, a number of flexible baffles are distributed on the inner wall of the external hose, which can enrich the flow trajectory of the water flow and form a more obvious time difference between the main connection head to the water gun head and the auxiliary connection head to the water gun head, thereby combining to achieve a water spray buffering effect and improve the accuracy of fire extinguishing.

[0010] Preferably, a water flow chamber is provided inside the water gun body, a diaphragm mounting groove is formed on the inner wall of the water flow chamber along its length direction, and the elastic water-isolating membrane is installed on the diaphragm mounting groove to separate the water flow chamber into the first water flow chamber and the second water flow chamber.

[0011] The elastic water-isolating membrane divides the water gun body into a first water flow chamber and a second water flow chamber. The water pressure in the two water flow chambers squeezes the elastic water-isolating membrane, causing the elastic water-isolating membrane to move in the length direction of the membrane mounting groove, thereby adjusting the volume of the two water flow chambers, thereby effectively improving the water flow stability during the water spraying process of the water gun.

[0012] Preferably, the water gun head is provided with a main body channel and a water spray bell mouth along its length direction, a spherical channel is formed between the main body channel and the water spray bell mouth, and a water retaining bead is provided in the spherical channel; A water spray plate is arranged at one end of the water spray bell mouth away from the main channel, and water spray holes are distributed on the water spray plate.

[0014] Preferably, the water supply source is a water tank, a water supply port is formed on the top of the water tank, and a water pump is also provided on the water tank to send the water inside the water tank out from the water supply port; An auxiliary support block is arranged on the lower surface of the auxiliary connector, and an auxiliary support ring is arranged on the outer sleeve of the water storage tank.

[0015] Preferably, the water supply source is a water supply truck, which is located on the ground and connected to the main connector via a water pipe.

[0016] Preferably, the fire extinguishing system is also provided with an auxiliary drone. At least one water pipe support frame is installed on the water pipe, and the water pipe is installed on the auxiliary drone through the water pipe support frame.

[0017] Preferably, the water pipe support frame includes a support frame body with two ends penetrated, the support frame body is provided with a plurality of pairs of pulleys for guiding the water pipe, and positioning blocks are provided at both ends of the corresponding area section of the water pipe to prevent the water pipe support frame from escaping from the area section.

[0018] Here, when extinguishing a fire at a high level, the main drone first drives the water gun upward to a certain height, and then the auxiliary drone moves upward to the corresponding area section on the water pipe, and makes the support frame body just fit on the corresponding area section; the main drone and the auxiliary drone fly to the fire area together, and then the main drone extinguishes the fire; in addition, since the corresponding area section on the water pipe has a certain length, the main drone can also move within a certain area to extinguish the fire, and the auxiliary drone is responsible for providing a perspective of the area; when the area needs to be changed, the auxiliary drone moves with the main drone, and then the auxiliary drone remains stationary, and the main drone extinguishes the fire in the new area.

[0019] The beneficial effects produced by the technical solution of the present invention are as follows: (1) A main water inlet and an auxiliary water inlet are arranged on the lower surface of the water gun body. The auxiliary water inlet can offset the reaction force on the pan / tilt body caused by the water gun spraying changes, thereby playing a buffering role. Moreover, it can also play a water replenishing role when the water flow is unstable or insufficient, thereby improving the stability of the water spraying.

[0020] (2) The first water flow chamber and the second water flow chamber are connected through an external hose. The external hose has a certain length and elasticity.

[0021] (3) The elastic water-isolating membrane divides the water gun body into a first water flow chamber and a second water flow chamber. The elastic water-isolating membrane is squeezed by the water pressure in the two water flow chambers, so that the elastic water-isolating membrane moves in the length direction of the membrane mounting groove, and the volume of the two water flow chambers is adjusted, which can effectively improve the water flow stability during the water gun spraying process.
