Description

Technical Field

[0001] The present invention belongs to the field of fire-fighting UAV balancing, and specifically relates to a fire-fighting UAV balancing device. Background Art

[0002] An unmanned aerial vehicle (UAV), also known as a drone, is an unmanned aircraft controlled by a radio remote control and its own programmable controller, or operated fully or intermittently autonomously by an onboard computer. Firefighting is a highly dangerous field, and the unmanned nature of drones makes them well-suited for these dangerous missions, leading to the increasing use of firefighting drones.

[0003] However, existing firefighting drones have the following main shortcomings:

[0004] 1. Poor balance. Firefighting drones need to carry a large amount of water, which results in a heavy body and large inertia. When the drone takes off or stops suddenly, the fuselage and propellers will tilt, causing the drone to become unbalanced.

[0005] 2. It is troublesome to install and remove the water bucket. The water bucket needs to be frequently installed and removed when the drone is fighting fires, and the existing drone fixing water bucket is troublesome.

[0006] Therefore, we made improvements to this and proposed a balancing device for fire-fighting drones. Summary of the Invention

[0007] In order to make up for the shortcomings of existing technologies and solve the problem of poor balance, fire-fighting drones need to carry a large amount of water, which leads to a heavy body weight and large inertia. When the drone takes off or stops suddenly, the fuselage and propeller will tilt, causing the drone to become unbalanced. It is troublesome to install and remove the water bucket. Since the drone needs to frequently install and remove the water bucket during firefighting, the existing drone has a more troublesome problem of fixing the water bucket.

[0008] The technical solution adopted by the present invention to solve the technical problem is: to provide a fire-fighting drone balancing device, including: a main body, an angle adjustment device and a fire extinguishing device;

An electric telescopic rod is fixedly provided at the bottom of the inner cavity of the fixed sleeve. A fixed block is provided for transmission at the bottom of the electric telescopic rod. A plurality of third connecting rods are hingedly provided around the fixed block. An end of the third connecting rod away from the fixed block is hinged to the center of the fifth connecting rod.

[0012] Furthermore, a camera is provided on one side of the top of the fuselage, and lighting lamps are provided on both sides of the camera. The buffer device includes two brackets, and the two brackets are symmetrically located on both sides of the bottom of the fuselage. The top of the bracket is hinged to the fuselage through a hinge seat, and a first sliding sleeve is provided between the two brackets.

[0013] During operation, the camera allows the device to transmit images from the front, facilitating operator control. The lighting allows the device to operate at night. The top of the bracket is hinged to the body via a hinged base, allowing the bracket to swing from the bottom of the body.

[0014] Furthermore, first sliding rods are slidably provided on both sides of the first sliding sleeve, one end of the first sliding rod away from the first sliding sleeve is hinged to the bracket, a spring is provided on the outer surface of the first sliding rod, and the first sliding rod is loosely fitted with the spring.

[0043] Furthermore, the second connecting rod 2004 passes through the inner wall of the fuselage 1001 and extends to the outside of the fuselage 1001. The bottom of the first connecting rod 2002 is provided with a penetrating slide groove 2003, and both ends of the second connecting rod 2004 are provided with grooves 2012. The groove 2012 is provided with a second slide rod 2013, and the second slide rod 2013 is slidably connected to the slide groove 2003.

[0044] During operation, the second slide bar 2013 is slidably connected to the slide groove 2003 , so that the second slide bar 2013 can slide in the slide groove 2003 .

[0045] Furthermore, a fourth link 3006 is provided on one side of the fifth link 3007, and the fourth link 3006 and the fifth link 3007 are parallel to each other. The two ends of the fourth link 3006 are respectively hinged to the bottom of the fixed sleeve 3001 and the clamping block 3008, and a water bucket 3002 is provided at the bottom of the clamping block 3008. A nozzle 3010 is provided on one side of the bottom of the fuselage 1001, and the nozzle 3010 extends to the interior of the water bucket 3002 through a hose. A water pump is provided inside the water bucket 3002, and the end of the hose away from the nozzle 3010 is connected to the water pump. A gyroscope sensor is provided inside the fuselage 1001.

[0046] During operation, the fourth connecting rod 3006 is hinged at both ends to the bottom of the fixing sleeve 3001 and the clamping block 3008, so that the fourth connecting rod 3006 can swing on the fixing sleeve 3001 and the clamping block 3008. A gyroscope sensor is provided inside the body 1001, so that the gyroscope sensor can detect the attitude angle of the device.

[0047] The specific workflow is as follows:

[0048] First, place the water bucket 3002 at the bottom of the fire extinguishing device 30, then start the electric telescopic rod 3009. The electric telescopic rod 3009 extends to drive the fixed block 3003 to move. The movement of the fixed block 3003 drives the third connecting rods 3005 to swing. The swing of the third connecting rod 3005 drives the fourth connecting rod 3006 and the fifth connecting rod 3007 to swing. The fourth connecting rod 3006 and the fifth connecting rod 3007 swing to clamp the water bucket 3002. Then control the device to fly to the place where the fire needs to be extinguished. When the device becomes unbalanced due to inertia, the gyroscope sensor measures the device's tilt angle and activates servo motor 2009. This rotation drives first bevel gear 2010, which in turn drives second bevel gear 2011. Second bevel gear 2011 rotates shaft 2007, which in turn drives rack 2005 and second connecting rod 2004. The movement of second connecting rod 2004 causes first connecting rod 2002 to swing, making first connecting rod 2002 perpendicular to the ground. This keeps propeller 2001 parallel to the ground. This ensures that even if drone fuselage 1001 tilts, propeller 2001 remains parallel to the ground, significantly reducing the probability of the device becoming unbalanced. When the device is moved to a location where a fire needs to be extinguished, the water pump is activated, pumping water through the water pipe and nozzle 3010 to extinguish the fire. When the device falls, the two side brackets 1101 move away from each other, compressing the spring 1102. The elastic force of the spring 1102 cushions the two side brackets 1101, thereby reducing the impact on the device. When the device falls, the first slide bar 1104 extends outward, moving the two side brackets 1101 away from each other, and then stretching the spring 1102. The tension of the spring 1102 cushions the two side brackets 1101, thereby reducing the impact on the device.

[0049] The above-mentioned front, back, left, right, up and down are all based on the Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
