Description

Technical Field

[0001] This utility model relates to the field of drone fire extinguishing equipment technology, specifically to a drone fire extinguishing device. Background Technology

[0002] Firefighting drones, as a new type of high-tech firefighting equipment, have received widespread attention and application in the firefighting field in recent years. By using drones equipped with water cannons to extinguish fires while hovering in the air, firefighters can be effectively prevented from directly entering the fire scene, improving firefighting efficiency and safety.

[0003] In related technologies, water-spraying drone fire extinguishing devices mostly consist of a water spray pipe installed at the bottom of the drone body, a connector installed at the water inlet of the water spray pipe, a hose installed at the water inlet of the connector, a booster pump installed at the water inlet of the hose, and a fire extinguishing water tank installed at the water inlet of the booster pump. The principle is to pump the fire extinguishing liquid in the fire extinguishing water tank to the hose through the booster pump, and then the hose supplies the water spray pipe. Based on the camera installed on the drone, the spray angle of the water spray pipe is controlled to continuously extinguish the fire source.

[0004] However, during the process of the booster pump supplying water to the hose, the drone will be affected by the impact force generated by the hose spray. This causes the communicating vessel joint to directly transfer the impact force to the drone body, thereby affecting the stability of the drone during flight. To solve the above problem, a drone fire extinguishing device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a fire extinguishing device for drones. The present invention supplies fire extinguishing liquid into the water tank and the spray pipe through a booster pump. At this time, the impact force of water pressure on the multi-rotor drone is reduced by the buffer component, thereby stabilizing the flight state of the multi-rotor drone. At the same time, the counterweight in the positioning device reduces the swing amplitude of the spray pipe, thereby reducing the impact of water pressure on the flight attitude of the multi-rotor drone and making the flight more stable.

[0006] To solve the above-mentioned technical problems, this utility model provides a drone fire extinguishing device, including a water spray pipe installed at the bottom of a multi-rotor drone, a connector installed at the water inlet end of the water spray pipe, a hose connected to the rear end of the connector, a booster pump installed at the water inlet end of the hose, a positioning component installed on the surface of the water spray pipe and connected to the bottom of the multi-rotor drone, a buffer component installed at the top of the connector and connected to the bottom of the multi-rotor drone, and a pressure regulating component connected between the hose and the booster pump.

[0007] The positioning component includes a positioning block installed on the bottom of the multi-rotor drone. The positioning block is used to connect and fix two arc-shaped plates to the bottom of the multi-rotor drone. An arc-shaped plate is symmetrically arranged on the bottom of the positioning block. The arc-shaped plate is used to fix the two ends of the slide rod. A slide rod is arranged between the arc-shaped plates. The slide rod is used to connect the connecting sleeve to the positioning block. The slide rod is also used for the water spray pipe to swing. A base is provided at both ends of the slide rod. The base is used to fix the slide rod to the arc-shaped plate, thereby preventing the slide rod from falling. Each slide rod is rotatably adapted to the base. The base is connected to the arc-shaped plate on the same side as it.

[0008] The positioning assembly also includes a connecting sleeve on the middle surface of the slide rod. The connecting sleeve is rotatably adapted to the slide rod and is used to connect the counterweight to the slide rod. A counterweight is provided at the bottom of the connecting sleeve. The counterweight is used to connect the positioning rod to the slide rod and also to limit the movement angle of the water spray pipe clamped at the bottom of the positioning rod, thereby reducing the excessive water spray angle when subjected to impact force. A pair of positioning rods are provided at the bottom of the positioning block. The positioning rods are used to fix the arc-shaped sleeve and also to connect the arc-shaped sleeve to the slide rod. Each positioning rod has an arc-shaped sleeve on the side near the water spray pipe. The arc-shaped sleeve is used to clamp the surface of the water spray pipe, thereby connecting the water spray pipe to the positioning assembly. The arc-shaped surfaces of the two arc-shaped sleeves are used to clamp the water spray pipe.

[0009] The inlet end of the communicating vessel is equipped with a water storage tank, which is used to temporarily store the fire extinguishing liquid supplied by the hose to the high altitude. This allows the water in the storage tank to reduce the impact force generated when the hose supplies water, thereby stabilizing the flight state of the multi-rotor UAV. A connecting block is provided on the top of the water storage tank, which is used to connect the water storage tank to the buffer assembly. The bottom of the connecting block is arc-shaped and connects to the surface of the water storage tank, while the top of the connecting block is rectangular and connects to the bottom of the buffer assembly. The bottom of the water storage tank is connected to the hose through a sealing joint.

[0010] The buffer assembly includes an upper buffer plate that connects to the bottom of the multi-rotor drone. The upper buffer plate is used to install rubber shock-absorbing columns, thereby connecting the rubber shock-absorbing columns to the bottom of the multi-rotor drone. Multiple rubber shock-absorbing columns are provided at the bottom of the upper buffer plate. The rubber shock-absorbing columns are used to reduce the impact force of water supply directly acting on the body of the multi-rotor drone. The shock absorption characteristics of the rubber shock-absorbing columns weaken the impact force of water pressure on the body of the multi-rotor drone, thereby stabilizing the flight. A lower buffer plate is provided at the bottom of the multiple rubber shock-absorbing columns. The lower buffer plate is used to fix the bottom of the rubber shock-absorbing columns. The bottom of the lower buffer plate is connected to the top of the connecting block. The lower buffer plate is also used to connect the rubber shock-absorbing columns to the water storage tank.

[0011] The pressure regulating assembly includes an extension pipe connected to the outlet of the booster pump. The extension pipe is used to install a pressure reducing valve. The outlet of the extension pipe is sealed to the hose. A pressure reducing valve is fixedly installed in the middle of the extension pipe. The pressure reducing valve is used to manually adjust the initial pressure supplied by the booster pump to the hose.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. The fire extinguishing liquid is supplied to the water tank and spray pipe through the booster pump. At this time, the impact force of water pressure on the multi-rotor drone is reduced by the buffer component, thereby stabilizing the flight state of the multi-rotor drone. At the same time, the counterweight in the positioning device reduces the swing amplitude of the spray pipe, thereby reducing the impact of water pressure on the flight attitude of the multi-rotor drone and making the flight more stable.

[0014] 2. The center of gravity of the counterweight is downward. The counterweight is used to connect the positioning rod and the sliding rod. The counterweight is also used to limit the movement angle of the water spray pipe clamped at the bottom of the positioning rod, thereby reducing the excessive water spray angle when it is subjected to impact force.

[0015] 3. The upper buffer plate is used to install rubber shock-absorbing columns, thereby connecting the rubber shock-absorbing columns to the bottom of the multi-rotor drone. The rubber shock-absorbing columns are used to reduce the impact force of water supply directly acting on the body of the multi-rotor drone. In this way, the shock absorption characteristics of the rubber shock-absorbing columns weaken the impact force of water pressure on the body of the multi-rotor drone, thereby stabilizing the flight.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

The buffer component 300 is connected to the bottom of the multi-rotor drone 100. A pressure regulating component 400 is installed between the hose 103 and the booster pump 104.

[0024] During use, the fire extinguishing liquid is supplied to the water tank 105 and the spray pipe 101 by the booster pump 104. At this time, the buffer component 300 reduces the impact force of water pressure on the multi-rotor drone 100, thereby stabilizing the flight state of the multi-rotor drone 100. At the same time, the counterweight 206 in the positioning device reduces the swing amplitude of the spray pipe 101, thereby reducing the impact of water pressure on the flight attitude of the multi-rotor drone 100. As a result, when the fire extinguishing liquid is supplied to the spray pipe 101, the flight attitude of the multi-rotor drone 100 is more stable.

[0025] This embodiment provides a drone fire extinguishing device.

The water storage cylinder 105 is cylindrical in shape and is connected to the communicating vessel 102 by a threaded seal. The water storage cylinder 105 is made of lightweight and environmentally friendly materials. The water storage cylinder 105 is used to temporarily store the fire extinguishing liquid supplied to the high altitude by the hose 103, so that the water in the water storage cylinder 105 weakens the impact force generated when the hose 103 supplies water, thereby stabilizing the flight state of the multi-rotor UAV 100.

[0031] Its effect is as follows: the water tank 105 is used to temporarily store the fire extinguishing liquid supplied by the hose 103 to the high altitude, so that the water in the water tank 105 weakens the impact force generated when the hose 103 supplies water, thereby stabilizing the flight state of the multi-rotor drone 100. The connecting block 106 is used to connect the water tank 105 to the buffer assembly 300.

[0032] like Figure 1 , 2 As shown in Figure 3: The buffer assembly 300 includes an upper buffer plate 301 connected to the bottom of the multi-rotor drone 100 at its top. The upper buffer plate 301 is fixed to the bottom shell of the multi-rotor drone 100 by bolts.

The outlet of the extension pipe 401 is sealed to the hose 103 by threaded union fittings. The pressure reducing valve 402 is fixedly installed in the middle of the extension pipe 401. The pressure reducing valve 402 is used to manually adjust the initial pressure supplied by the booster pump 104 to the hose 103.

[0035] Its effect is as follows: the pressure reducing valve 402 is used to manually adjust the initial pressure supplied by the booster pump 104 to the hose 103, thereby reducing the water pressure from the initial end.

[0036] Working principle: The booster pump 104 draws fire extinguishing liquid into the hose 103, which then enters the water tank 105. At this time, the buffer component 300 reduces the impact force of water pressure on the multi-rotor drone 100, thereby stabilizing the flight state of the multi-rotor drone 100. At the same time, the counterweight 206 in the positioning device reduces the swing amplitude of the water spray pipe 101, thereby reducing the impact of water pressure on the flight attitude of the multi-rotor drone 100. As a result, when fire extinguishing liquid is supplied to the water spray pipe 101, the flight attitude of the multi-rotor drone 100 is more stable.
