Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, and more specifically to a multi-rotor unmanned aerial vehicle and a rapid response fire fighting system. Background Art

[0002] With the progress of society, there are more and more high-rise buildings in cities, and the fires in high-rise buildings are becoming increasingly frequent. Due to the characteristics of high-rise buildings, once a fire occurs, the fire spreads rapidly, resulting in frequent occurrence of serious accidents, causing huge losses to society and families. At present, when a fire occurs in a high-rise building, fire trucks are still relied on for fire fighting. However, the limitations of fire trucks are very large. Since their response speed cannot catch up with the spread speed of the fire in high-rise buildings, by the time the fire truck arrives, the fire has passed the initial stage when it is easy to control, and the rescue effect is not satisfactory. For high-rise buildings, such as buildings, especially when a fire breaks out in a super high-rise building, the height that the fire truck ladder and the fire hose can spray water cannot reach the required height, and there will be a situation where rescue is impossible, resulting in heavy property losses and casualties. If firefighters enter the building to rescue people or fight the fire, it will endanger the lives of firefighters, and in addition, the rescue speed is slow. There are also unmanned aerial vehicles used for fire fighting, but due to the insufficient lifting capacity of the unmanned aerial vehicle, it cannot provide continuous and sustained water flow, and the fire extinguishing effect is not good.

[0003] For example, Chinese Patent Publication No. CN205168931U discloses a fire fighting unmanned aerial vehicle based on a rescue device, including a top wing, a signal transceiver, a camera monitor, a protection device, a rescue device, a concentration detector, and a material bin opening. The signal transceiver is provided under the top wing through screws, the camera monitor is provided on one side of the signal transceiver through bolts, the protection device is provided under the camera monitor through a connecting shaft, the concentration detector is provided in the middle of the protection device, and the rescue device is provided under the protection device. This fire fighting unmanned aerial vehicle based on a rescue device, through the setting of the protection device, has an explosion-proof and anti-impact device, improving safety protection and versatility; through the design of the rescue device, timely rescue of trapped people is realized, reducing the casualty rate; through the design of the concentration detector, the concentration detection of various toxic and harmful gases is realized, improving the accuracy of disaster situation analysis. However, it does not have the function of extinguishing the fire source. Existing unmanned aerial vehicles with a water spraying function usually connect a water pipe from the ground for high-altitude water spraying. The water pipe containing water is heavy, and for higher floors, the ability of such unmanned aerial vehicles is limited and the control is not convenient enough. Summary of the Utility Model

[0004] 1. Technical Problems to be Solved by the Utility Model

[0005] Aiming at the problem that the existing fire-fighting technology has limited fire-fighting ability for higher floors, the utility model provides a multi-rotor unmanned aerial vehicle and a rapid-response fire-fighting system. The vertical pipe fixedly connected to the body of the multi-rotor unmanned aerial vehicle is used to connect the water source at the top of the building, and water is transported from top to bottom to the fire source. The unmanned aerial vehicle has a small load, is flexible and can achieve the purpose of extinguishing fire in time.

[0006] 2. Technical solution

[0007] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0008] This technical solution creatively redefines the functions of the unmanned aerial vehicle and the water pipe to give full play to their respective advantages. In the system, through the winding and unwinding of the coiled pipe device, the length of the hose dropped from the top of the building effectively controls the height of the unmanned aerial vehicle. While creatively endowing the system of the utility model with the function of uninterrupted water supply, it is also used to control the take-off and landing height of the unmanned aerial vehicle, so that the unmanned aerial vehicle no longer relies on the rotor of the unmanned aerial vehicle to provide power for lifting and lowering. This solves the problem that the water source cannot reach the required height when extinguishing fires in high-rise buildings, and realizes effective fire-fighting for high-rise buildings. A safety wire is also bound and arranged on the hose to supply power to the unmanned aerial vehicle, so that the unmanned aerial vehicle no longer needs battery power supply, reducing the weight of the unmanned aerial vehicle. The function positioning of the system of the utility model for the unmanned aerial vehicle is that its rotor power is only used to control the horizontal movement of the unmanned aerial vehicle and the change of the horizontal angle, realizing controllable water flow direction.

[0009] A multi-rotor unmanned aerial vehicle in this technical solution includes a fuselage. The circumferential direction of the fuselage is connected with rotors with a vertical axis through connecting rods. It also includes a vertical pipe and a horizontal pipe. The vertical pipe is in the middle of the fuselage. The top of the vertical pipe is connected with a pipe joint for externally connecting a hose that continuously supplies water from above. The bottom end of the vertical pipe is connected and communicated with the horizontal pipe. An electronically controlled water valve is provided on the pipeline of the vertical pipe and the horizontal pipe to control the water flow and water pressure in the horizontal pipe, and to control the water flow switch and flow rate. After the vertical pipe is externally connected to the continuous water source above, the coiled pipe device controls the length of the hose hanging outside the building, thereby controlling the height of the unmanned aerial vehicle connected to the hose. When it ascends or descends to the height of the fire source, the rotor of the unmanned aerial vehicle controls the horizontal movement of the unmanned aerial vehicle to the fire source, and the rotor of the unmanned aerial vehicle controls the change of the horizontal angle of the unmanned aerial vehicle, so that the water spraying port points to the fire source, and water is sprayed at the fire source through the horizontal pipe, thereby achieving the effect of extinguishing fire in time.

[0010] The facilities of this technical solution can be in a standby state, and the fire-fighting response is rapid and timely.

[0011] In a further technical solution, multiple horizontally axial rotors are arranged at the rear in the direction of the horizontal pipe. The thrust generated by them is used to compensate for the recoil force generated after the horizontal pipe sprays water, so as to stabilize the flight of the unmanned aerial vehicle, fly stably towards the fire source, and make the water spray reach the ignition point.

[0012] In a further technical solution, an electronically controlled water valve is provided on the vertical pipe and / or the horizontal pipe to control the water spraying switch and the water flow rate.

[0013] The horizontal pipe is provided with a pitching mechanism, and the horizontal pipe can perform a small-amplitude pitching motion. On the one hand, it increases the water spraying coverage area, and on the other hand, it enables the water flow to accurately reach the ignition point, improving the fire extinguishing efficiency.

[0014] In a further fire protection system, it further includes a bracket fixed to the top of the building; the bracket is in an inverted L shape, the upper horizontal section of the bracket can extend beyond the top of the building, the vertical support column of the bracket is rotatably connected to the support platform on the top of the building and has the function of rotating with the support platform, and the horizontal section preferably has a telescopic section with a telescopic function. On the one hand, it increases the fire protection coverage area of the entire system, and on the other hand, when the system is in a standby state, the entire system is within the building boundary, which is convenient for maintenance and management.

[0015] The bracket is used to support the hose and is provided with a hose support device, such as setting pulleys at the corners to enable the hose to move smoothly on them, so as to realize the retraction and extension of the hose and ensure the smooth takeoff and landing of the drone. One end of the hose bound with the soft cable is coiled in the disc of the coiling device, and the disc has a driving device and can rotate around the center. In one direction, the hose is coiled into the disc to retract the hose, and in one direction, the hose is released. The hose is connected to the water source, and at the same time, the soft cable is connected to the power supply in an insulated state. The other end of the hose is connected to the vertical pipe of the drone, and at the same time, the soft cable is electrically connected to the power receiving column of the drone, connecting the water source at the top of the building to the drone, and controlling the takeoff and landing of the drone by the coiling device, and providing continuous water source from top to bottom for the multi-rotor drone to continuously extinguish the fire, thus greatly reducing the load on the drone body and the requirements for the lift configuration of the rotors.

[0016] In a further fire protection system, it further includes a power supply on the top of the building, which supplies power to the drone body through the soft cable in the hose. The body does not need to carry an overly heavy battery, and the power consumption mainly comes from the power provided by the external power supply, enabling it to have continuous endurance and further reducing the requirements for the load configuration of the drone itself.

[0017] A fire extinguishing method for the above-mentioned rapid response fire protection system, the steps are as follows:

[0018] S1. Rotate the bracket to extend the horizontal section out of the building, adjust the extension length of the horizontal section so that the top of the horizontal section is close to the fire source in the horizontal direction, fill the hose with water to make it in a high-pressure water supply state, rotate the disc, extend the hose, lower the drone to a height close to the fire source, open the valve, and the horizontal pipe of the drone starts to spray water. After the drone reaches the fire source height, the disc in the coiling device stops rotating, the coiling stops releasing the hose, the drone height is maintained, the drone moves horizontally to the fire source, and the horizontal pipe is aligned with the fire source to spray water by the rotors and adjusting the rotors.

[0019] S2. After extinguishing the fire, start the coil device to retract the hose, close the valve, and the multi-rotor drone with the hose rises to the top of the building. The horizontal section of the bracket retracts, and the bracket column rotates to return the drone to its original position.

[0020] 3. Beneficial effects

[0021] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0022] (1) The rapid response fire fighting system based on a multi-rotor drone of the present utility model is especially suitable for ultra-high floors. It can be connected to the fire alarm system of ultra-high floors. After promptly responding to a fire alarm, it is flexible and can quickly take off and land at the fire point to sprinkle water in a timely manner. Sprinkling water when the fire is still small can avoid the spread of the fire and achieve the effect of extinguishing the fire in a timely manner.

[0023] (2) In the rapid response fire fighting system based on a multi-rotor drone of the present utility model, the drone does not need to be equipped with a battery, and the power consumption mainly comes from the power provided by an external power source, so it has the effect of long endurance. It solves the problem of insufficient endurance caused by the small battery power of the drone and reduces the weight of the drone itself, improving its mobility.

[0024] (3) In the rapid response fire fighting system based on a multi-rotor drone of the present utility model, the power for the up and down movement of the drone does not need to be achieved by the work of the drone rotors, but is instead achieved by the retraction and release of the coil device. Thus, it no longer consumes electrical energy due to rising, falling, or hovering, reducing the requirement of the drone for lifting capacity; this creative method enables fire extinguishing to be no longer restricted by the height of the building; adjusting the rotors is mainly used to control the attitude and direction of the drone, and only controls the pointing of the horizontal water pipe to control the horizontal angle, so that the direction and angle of the discharged water flow can be controlled, achieving the purpose of multi-angle fire fighting.

[0025] (4) In the rapid response fire fighting system based on a multi-rotor drone of the present utility model, at the rear of the horizontal water pipe, an adjusting rotor with an axis consistent with the horizontal water pipe is provided, which can be synchronously coordinated with the valve switch to compensate for the recoil generated when the horizontal water pipe of the drone sprays water, making the drone operate more stably, making it easier to control the spraying direction, and enabling the water flow to be ejected far while ensuring the stable controllability of the drone.

Detailed implementation mode

[0029] To further understand the content of the present utility model, the utility model will be described in detail with reference to the accompanying drawings.

[0030] Embodiment 1

[0031] The fast - response fire - fighting system based on a multi - rotor unmanned aerial vehicle in this embodiment, as Figure 2 shown, includes a multi - rotor unmanned aerial vehicle 6, and a water source 2 and coil pipe equipment 4 respectively arranged on the top of a building 1; the water source 2 is generally a water tank or a high - pressure fire hydrant.

[0032] As Figure 1 shown, the multi - rotor unmanned aerial vehicle 6 includes a fuselage 61. The circumferential direction of the fuselage 61 is connected with rotors 63 with an axial direction of vertical through connecting rods. There can be multiple rotors 63, such as 3 or more than 3; it also includes a vertical pipe 62 and a horizontal pipe 66. A connecting hole runs vertically through the middle of the fuselage 61. The vertical pipe 62 is vertically and fixedly connected to the connecting hole, or can also be slidably connected to the connecting hole to improve the mobility of the multi - rotor unmanned aerial vehicle 6; the bottom end of the vertical pipe 62 is connected and communicated with the horizontal pipe 66 through a connecting piece 65. When the horizontal pipe 66 is single, the connecting piece 65 can be selected as a right - angle joint; the horizontal pipe 66 can also be multiple to expand the water spraying surface. At this time, the connecting piece 65 needs to be selected as a multi - way joint, such as a three - way joint or a joint with three or more ways, and configured accordingly according to the number of horizontal pipes 66. When the connection between the horizontal pipe 66 and the vertical pipe 62 is a flexible soft connection, such as through a metal corrugated pipe connection, the water spraying direction can be adjusted flexibly.

[0033] On the back of the connecting piece 65, the fuselage 61 is fixedly connected with an adjustable rotor 64 through a connecting rod to push the horizontal pipe 66 closer to the fire source, and under the cooperative action with the rotor 63, adjust the water spraying angle of the horizontal pipe 66.

[0034] At the top of the vertical pipe 62, there is a pipe joint 68 connected. The water outlet end of the hose 41 in the coil pipe device 4 is connected to the vertical pipe 62 through the pipe joint 68; the water inlet end of the hose 41 is connected to the water source 2, and a water supply valve 42 is arranged at the connection between the two. After the vertical pipe 62 is externally connected to the upper water outlet hose 41, the rotor 63 pulls the hose 41 to the fire source, and sprays water at the fire source through the horizontal pipe 66, providing continuous water source from top to bottom for the multi-rotor drone 6 to continuously extinguish the fire, thereby achieving the effect of timely fire extinguishing. An electric control water valve 621 is arranged on the vertical pipe 62 and / or the horizontal pipe 66 to control the water spray amount. An execution module for controlling the pitching swing of the horizontal pipe 66 is added to the control system of the fuselage 61.

[0035] In specific applications, after the fire alarm system of the building 1 gives an alarm, the fire alarm system sends the fire source fire point to the fast response fire fighting system of this embodiment. The steps of the fire extinguishing method are as follows:

[0036] S1. The system first rotates the bracket and extends the horizontal section to place the drone outside the building. The coil pipe device 4 is started to release the hose 41, and the fuselage 61 is controlled by the coil pipe device 4 to descend to the height of the fire source. The water supply valve 42 and the electric control water valve 621 are opened, and the coil pipe device 4 stops releasing the hose 41; the multi-rotor drone 6 moves horizontally to near the fire source and pulls the hose 41 to the fire source.

[0037] S2. The horizontal pipe 66 is aligned with the fire source to spray water through the rotor 63 and the adjustable rotor 64. The execution module for controlling the pitching swing of the horizontal pipe 66 is opened to control the water spray direction and the water landing position, and three-dimensional spraying is carried out on the fire source in the front, back, up, down, left, and right directions.

[0038] S3. After the fire is extinguished, the water supply valve 42 and the electric control water valve 621 are closed. The system starts the coil pipe device 4 to recycle the hose 41. The hose 41 pulls the multi-rotor drone 6 to rise and return to the top of the building 1, and the horizontal section of the bracket 5 is retracted.

[0039] The fast response fire fighting system based on the multi-rotor drone of this embodiment is especially suitable for ultra-high floors. Connected to the fire alarm system, after timely responding to the fire alarm, the drone of the system is flexible and can quickly take off and land at the fire point to sprinkle water, and sprinkle water in time when the fire is still small, so as to avoid the spread of the fire and achieve the effect of timely fire extinguishing; the power for the up and down movement of the drone can be realized not by the work of the drone rotor, but by the retraction and release of the coil pipe device 4. The coil pipe device 4 controls the takeoff and landing of the drone, so that the electric energy is no longer consumed due to rising, descending or hovering, and the requirement of the drone for lifting capacity is reduced, thus greatly reducing the load of the drone fuselage and the lift configuration requirement of the rotor; the power of the adjustable rotor 64 is mainly used to control the attitude of the drone, and only controls the pointing of the horizontal water pipe 66, including horizontal, vertical and horizontal angles, so that the direction and angle of the discharged water flow can be controlled, and the water flow direction can be controlled to achieve the purpose of multi-angle fire fighting.

[0040] Example 2

[0041] The rapid response fire fighting system and its application in this embodiment have the same basic structure and steps as those in Embodiment 1. The differences or improvements are as follows: It further includes a power supply 3 and a bracket 5 fixed on the top of the building 1. The coil pipe device 4 is located between the water source 2, the power supply 3 and the bracket 5, which is convenient for connecting to the water source 2 and the power supply 3 nearby. The power supply 3 can be an electric control cabinet.

[0042] The power supply 3 supplies power to the fuselage 61 through a flexible cable 31. The fuselage 61 does not need a battery with an overloaded load. The power consumption mainly comes from the power provided by the external power supply 3, enabling it to have continuous endurance ability, reducing the weight of the unmanned aerial vehicle itself, and further reducing the requirements for the load configuration of the unmanned aerial vehicle itself.

[0043] The bracket 5 is in an inverted L-shaped frame structure. The upper horizontal section of the bracket 5 extends out of the top of the building 1 to ensure that the unmanned aerial vehicle can smoothly take in and release the wire when taking off and landing. After the flexible cable 31 and the hose 41 are bound and connected, they are taken in and released to the outside of the building 1 through the entire bracket 5. After the end of the flexible cable 31 passes through the edge of the pipe joint 68, it is electrically connected to the fuselage 61; the end of the hose 41 is connected to the vertical pipe 62 through the pipe joint 68. The bracket 5 is rotatably connected to the support platform 7 on the top of the building 1 to facilitate the rotation of the entire bracket 5 along with the unmanned aerial vehicle and expand the fire fighting area.

[0044] In the rapid response fire fighting system based on a multi-rotor unmanned aerial vehicle in this embodiment, there is no need to configure a battery in the fuselage 61 of the unmanned aerial vehicle. The power consumption mainly comes from the power provided by the power supply 3 on the top of the building 1, enabling it to have the effect of continuous endurance ability, solving the problem of insufficient endurance time caused by the small battery power of the unmanned aerial vehicle, reducing the weight of the unmanned aerial vehicle itself, and improving the maneuverability and flexibility.

[0045] The control module for adjusting the rotor 64 in the fuselage 61 is preferably synchronized with the switch control module of the electric control water valve 621 to compensate for the recoil force generated when the horizontal pipe 66 of the unmanned aerial vehicle sprays water; when the horizontal pipe 66 sprays water, with the generation of a reaction force during spraying, the motor and rotor blades of the adjusting rotor 64 generate corresponding thrusts to overcome the reaction force generated during spraying; the unmanned aerial vehicle runs more stably, is easier to control the spraying direction, enables the water flow to be sprayed far and ensures that the unmanned aerial vehicle is stable and controllable.

[0046] Example 3

[0047] The quick-response fire-fighting system of this embodiment and its application have the same basic structure and steps as those of Embodiment 2. The differences or improvements are as follows: The horizontal section of the bracket 5 with an inverted L-shaped frame structure preferably has a telescopic section with a telescopic function. The vertical support column of the bracket 5 is rotatably connected to the support platform 7 at the top of the building 1. The bracket 5 is used to support the hose 41 and the flexible cable 31, and is provided with rolling support members. For example, a fixed pulley is fixed at the corner of the L-shaped frame structure, so that the hose 31 can roll smoothly around the fixed pulley to realize the retraction and extension of the hose 41 and the flexible cable 31, ensuring the smooth takeoff and landing of the drone. One end of the hose 41 bound to the flexible cable 31 is coiled in the disc of the coiling device 4. The disc has a driving device and can rotate around the center. One direction winds the hose 41 into the disc to retract the hose 41, and the other direction releases the hose 41. The hose 41 is connected to the water source 2, and at the same time, the flexible cable 31 is connected to the power supply 3 in an insulated state. The other end of the hose 41 is connected to the vertical pipe 62 of the drone. At the same time, the flexible cable 31 is electrically connected to the power receiving column of the drone, connecting the water source 2 at the top of the building to the drone. The coiling device 4 controls the takeoff and landing of the drone, and provides continuous water source from top to bottom for the multi-rotor drone to continuously extinguish fires, thus greatly reducing the load on the drone body and the requirements for the lift configuration of the rotors.

[0048] The fire extinguishing method of the quick-response fire-fighting system of this embodiment is as follows:

[0049] S1. Rotate the bracket 5 to extend the horizontal section out of the building 1, adjust the extension length of the horizontal section so that the top of the horizontal section is closer to the fire source in the horizontal direction, fill the hose 41 with water to make it in a high-pressure water supply state, rotate the disc, release the hose 41, lower the drone to a height close to the fire source, open the water supply valve 42 and the electric control water valve 621, and the horizontal pipe 66 of the drone starts to spray water. After the drone reaches the fire source height, the disc of the coiling device 4 stops rotating, and the coiling device 4 stops releasing the hose 41. The height of the drone is maintained, and the drone moves horizontally to the fire source, and the horizontal pipe is aligned with the fire source to spray water by adjusting the rotor 63 and the rotor 64.

[0050] S2. After extinguishing the fire, start the coiling device 4 to recover the hose 41, close the valve, and the hose 41 pulls the multi-rotor drone to rise to the top of the building. The horizontal section of the bracket 5 retracts, and the support column rotates to return the drone to its original position.

[0051] The above schematically describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention. The actual structure and manufacturing steps are not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments to this technical solution without creative efforts without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
