Description

A water rescue drone

technical field

The invention belongs to the technical field of water rescue, in particular to a water rescue drone.

Background technique

Water life-saving equipment is a kind of water protective equipment to ensure the safety of those who are active in waters or drowning in water. It is widely used in fishing, water operations, water sports and other activities and special industries and departments such as customs anti-smuggling troops.

At present, with the development of economy and technology at home and abroad, the equipment for water rescue and life-saving is becoming more and more diversified. In the research of water life-saving devices, domestic scholars have mainly done related research on water rescue robots and ejection life-saving devices.

(1) Water rescue robot

The new type of water rescue robot developed by East China Jiaotong University fully considers the human factor, and integrates manual and automatic control methods, which greatly improves the convenience of operation.

In order to improve the probability of people being rescued when people are in danger on the water, this robot has multiple robots placed on each ship. In the real use link, it must be thrown around the drowning person in order to play its maximum role. If it is not suitable, it will be difficult for the drowning person to get rescue. In response to this problem, East China Jiaotong University has developed a water rescue robot. When someone falls into the water, it will assist the drowning person by throwing the water rescue robot, so that they can float safely on the water. Waiting for rescue, it will not reduce the probability of successful rescue due to struggle and collapse, but in fact, even if the traditional lifebuoy is thrown out, in case of deviation or miscalculation of the direction of the water flow, the drowning person will take it. The people on the boat go into the water for rescue, which increases the danger. This water rescue robot improves this defect, but the price is too expensive and it is not convenient to popularize.

(2) Ejection-type water life-saving device

A catapult-type water life-saving device jointly developed by Shandong University and Huazhong University of Science and Technology, the delay and inflatable modules are the main components of the device. Through the full research and development of these two parts, the rescue efficiency of the device has been greatly improved, so as to achieve the purpose of rescue of drowning persons.

The end of the drawstring and the self-inflating lifebuoy shell are fixed to the stopper of the crossbow chute, and a lot of energy is stored in the leaf spring. When carrying out rescue, only the relevant personnel need to aim the equipment on the water next to the drowning person, and then press the switch, the lifebuoy can be bounced into the water, and the lifebuoy can be automatically inflated. After the lifebuoy is caught by the drowning person, the rescuer can pull the reel to rescue the drowning person out of the drowning area. But if the ejection position is not accurate, the rescue will fail.

Current status of foreign research

(1)U Safe lifebuoy

U Safe is a water automatic mobile lifebuoy developed by a Portuguese company. When rescuing the drowning person, the rescuer only needs to use the remote control to remotely control the lifebuoy to the side of the drowning person, thus greatly ensuring the safety of the rescuer. However, it has fewer functions, and some problems may occur in emergencies.

Today, the development of water rescue and life-saving devices has achieved certain achievements, but there are still certain problems. For example, if there is danger in some traditional waters, it is still only relying on traditional rescue equipment such as lifebuoys and life jackets for rescue work. Rescuing people in danger in water is very different from rescuing people on land. In this regard, not only rescue personnel but also rescue equipment are put forward higher requirements. However, there are still major deficiencies in the actual rescue: the first aspect is the immaturity of the rescue team; the second aspect is that professional rescue equipment is still very scarce.

There are many disadvantages of the existing rescue methods of lifesaving devices. First, the rescued person is required to perform almost all operations. If the throwing position of the lifebuoy is not accurate, they must swim to the lifebuoy and put it on the body. , For the rescued who lack the ability to save themselves, this is almost impossible to achieve. Secondly, in other harsh environments, such as strong winds and waves, and whirlpools, it is difficult for the rescued to swim near the lifebuoy, which increases the difficulty of rescue. In addition, in emergency situations, every second is racing against time for rescue, and rescuers sometimes have improper operations, thus missing the best rescue opportunity.

The lighting device 8 can provide a light source, so as to meet the needs of rescue at night. At the same time, the lighting device 8, like the imaging device 7, expands the lighting range by the swing of the rotating base 9.

As a preferred example, the rotation range of the rotating base 9 is a range of 90° based on the vertical direction. The rotating base 9 can be turned into a vertical state, so that the camera device 7 and the lighting device 8 can face the water surface directly below.

As a preferred example, the clamping jaw 6 includes a sleeve 6.1, a pair of connecting rods 6.2, a pair of claw bodies 6.3, a pull rod 6.4 and a tension spring 6.5; the sleeve 6.1 has a central hole 6.11, and the pull rod 6.4 is slidably installed in the central hole 6.11 and the bottom Protruding from the sleeve 6.1, the claw body 6.3 is symmetrically hinged to the bottom of the pull rod 6.4, the connecting rod 6.2 is symmetrically hinged and installed on the outer wall of the sleeve 6.1, the other end of which is hingedly connected to the corresponding claw body 6.3, and the tension spring 6.5 is arranged in the center hole In 6.11, one end is connected to the sleeve 6.1, and the other end is connected to the top of the tie rod 6.2. When no other external force acts, the tension spring 6.5 is in a retracted state, and the claw body 6.3 is closed at this time, and the lifebuoy 5 is grasped. When the lifebuoy 5 is pulled, the claw body 6.3 is acted by the force of the lifebuoy 5, and the tension spring 6.5 is stretched, so that the claw body 6.3 is opened.

As a preferred example, the fuselage 1 has four fixing bases 1.11. The fixing bases 1.11 are installed with a swing arm 2 rotatably horizontally. The swing arm 2 can be put away after the work is finished, which is convenient for the storage of the whole machine.

The bottom cover 1.2 is fixed at the bottom opening of the casing 1.1 by screws. When maintenance or replacement of internal components is required, unscrew the screws and open the bottom cover 1.2. The supporting cotton 14 corresponds to the position of the battery of the power supply device 13 , so that the battery is firmly placed in the battery box to prevent loosening and affecting the power supply.

During the rescue, the user operates the drone to carry the lifebuoy 5 to the accident site. When the drowning person is found, the hoisting device 12 of the drone is activated to quickly release the rope 10, and the lifebuoy 5 falls to the side of the drowning person. The person grabs the lifebuoy 5 to obtain buoyancy to get out of the predicament, and then the hoisting device 12 runs in the reverse direction to take up the rope 10. At this time, the claw body 6.3 is opened under the thrust of the lifebuoy 5 to escape from it. Then the drone flew back to the shore, and the drowning person floated on the water with the help of lifebuoy 5 and waited for the next rescue.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the technical principles of the present invention, several improvements and modifications can be made.
