Description

Technical Field

[0001] The present invention discloses a multi-support life-saving structure for an ice surface rescue drone and an ice surface rescue drone, which relate to a life-saving structure installed on an ice surface rescue drone, and belong to the technical field of ice surface rescue, and particularly to a life-saving structure that can provide support for multiple people who fall into water at the same time and improve the efficiency of ice surface rescue by storing multiple life-saving equipment through a placement plate, a convex plate and a box body. Background Art

[0002] When the weather is cold, the river surface will freeze due to the drop in temperature. Affected by factors such as sunlight, water flow speed, wind force, and nearby human activities, the thickness of the ice layer in different areas of the river surface is different. When people skate on the ice, it is difficult to accurately judge the thickness of the ice layer with the naked eye. The pressure on the ice layer caused by skating on the ice surface for a long time and the influence of sunlight will cause the ice layer to crack, which is prone to falling into the water. According to measurements, people will lose sensation in their limbs after 15 minutes in water below 0°, and in water between 0° and 10°, their limbs will become numb and stiff after 4 minutes, and they will lose the ability to save themselves and cooperate with rescue. Therefore, it is necessary to rescue people who fall into the water in time. At present, the main method of ice rescue is manual. Rescuers tie safety ropes on the shore, and then carry ladders, lifebuoys and other tools to climb ice to reach the location of the person who fell into the water and rescue the person who fell into the water. Because the friction of the human body on the ice surface is small, rescuers will slide back and forth on the ice surface. Manual rescue is inefficient and labor-intensive, and there is a risk of rescuers falling into the water.

[0003] Announcement No. CN206968953U discloses a remote-controlled ice rescue robot, including a shell and a remote control. A support plate is provided on the inner side wall of the shell, and an automatic wire reel and a rope thrower are provided on the support plate. The automatic wire reel and one end of the rope are fixed, and an ice claw is fixed to the other end of the rope. A support rod is provided between the rope thrower and the support plate. A throwing port is provided on the shell opposite to the rope thrower, a ventilation window is provided on the side wall of the shell, and a handle is provided on the outside of the ventilation window. A heater is provided in the shell opposite to the ventilation window. A motor, a blower and a controller are also provided in the shell. The blower is connected to the airbag through an air supply pipe. The bottom of the shell is fixed to one end of a connecting rod, and a driving wheel and a driven wheel are provided on the other end of the connecting rod. The driving wheel and the driven wheel are connected by tracks. The ice rescue robot drops crampons onto the ice surface, fixes the crampons on the ice surface, and then the person who falls into the water grabs the handle and pulls the person out of the water. However, the crampons are only fixed on the ice surface, and under the pressure and shaking of the person who falls into the water, the crampons may loosen, and the ice rescue robot may fall into the water, making it impossible to continue rescuing the person who falls into the water. Moreover, the ice rescue robot only pulls the person who falls into the water out of the water, but cannot quickly bring the person back to the shore. After being soaked in water for a long time, the person who falls into the water will experience numbness and stiffness of the limbs and needs timely medical treatment. However, the rescuers cannot quickly reach the rescue site to treat the person who falls into the water due to the slippery ice surface, resulting in the person who falls into the water being unable to quickly recover his body functions.

[0004] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "An Ice Rescue Drone". When there are multiple people falling into the water, after a person falls into the water grabs the first handle, he can take out the life-saving equipment such as the life-saving ball and life buoy stored in the box and throw them to other people who fall into the water to provide support for them. However, the box space on the above-mentioned ice rescue drone is limited, and it is impossible to place multiple life-saving equipment at the same time. When there are multiple people falling into the water, the number of life-saving equipment may be difficult to meet the demand, and it is impossible to provide support for multiple people who fall into the water at the same time; and only linear life-saving equipment such as traction ropes can be stored in the box, and cannot be hung. The space utilization rate of the box is low, and the life-saving equipment is easily tangled together, which is inconvenient to take; Summary of the invention

The controller and the monitoring background establish signal interaction, The signal converter is connected to the data processor via a data transmission line, and the data processor is connected to the controller via a data transmission line. The signal converter can convert the electrical signal of the image data collected by the camera into a digital signal. The controller can be implemented by one or at least two application-specific integrated circuits (ASICs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors or other electronic components for executing instructions of the data processing device. The data processor and the signal converter perform information exchange, When the control system is executed, the following steps are mainly implemented: The support platform is installed on the river bank, and the pad is stored on the bottom surface of the machine body through the adsorption force of magnets and iron sheets. When the monitoring background receives an alarm call that someone has fallen into the water, the position of the person who has fallen into the water and the distance to the support platform are determined, and the outbound flight route and the return glide route are set for the machine body. The controller starts the first motor and the second motor.

The camera collects image data of the ice surface and sends the collected image data signal to the signal converter. The signal converter converts the electrical signal of the received image data signal into a digital signal and sends it to the data processor. The data processor processes the digital signal of the received image data and identifies the brightness value in the image data. When the brightness value of the image is lower than the preset brightness value, an execution instruction is sent to the controller. The controller controls the lighting to start. When the machine body approaches the water surface where the person who has fallen into the water is located, the controller controls the first motor to start. The first motor stops and the second motor stops, the horn starts, and the machine body floats on the water surface through the floats on both sides. The monitoring background reminds the person who falls into the water through the horn to grab the first handle, open it and climb onto the mat. When there are multiple people who fall into the water, after a person who falls into the water grabs the first handle, he can take out the life-saving equipment such as the life-saving ball and the life buoy stored in the box and throw them to other people who fall into the water to provide support for them. The pressure sensor collects the pressure data on the first handle and sends the collected pressure data signal to the signal converter. The signal converter converts the electrical signal of the received pressure data signal into a digital signal and sends it to the data processor. The data processor processes the digital signal of the received pressure data. When the pressure data is greater than the preset pressure data, it means that the person who falls into the water has grasped the first handle, and sends an execution instruction to the controller. The controller controls the first motor to start, the first motor drives the second shaft to rotate, the second shaft drives the pull rope to rotate, and the pull rope drives the machine body to slide along the preset return route. The sliding force of the skateboard and the mat on the ice surface and the pulling force of the pull rope drive the person who falls into the water to return to the support platform, thereby completing the rescue of the person who falls into the water. Furthermore, a second handle is disposed on the side of the floating body, and there are two second handles, and the two second handles correspond to the floating body one by one. Furthermore, the vertical sliding plate is replaced by a wide sliding plate, and the width of the wide sliding plate is greater than the width of the vertical sliding plate. Beneficial Effects

[0008] 1. By placing plates and convex plates in conjunction with the box to store multiple life-saving equipment, it is possible to provide support for multiple people who fall into the water at the same time, thereby improving the efficiency of ice rescue.

[0009] Second, by placing one end of the life rope into the round hole and fixing the other end of the life rope on the body of the person who fell into the water, the drone can simultaneously bring multiple people who fell into the water back to the support platform, thereby improving the efficiency of ice rescue.

Example 2

[0017] The difference between this embodiment and embodiment 1 is that a second handle (41) is arranged on the side of the floating body (7), and there are two second handles (41), and the two second handles (41) correspond to the floating body (7) one by one. When in use, a person who falls into the water can obtain support by grasping the second handle (41) and climb onto the ice surface, or can return to the support platform (3) driven by the body (30) through the sliding force on the ice surface and the pulling force of the pull rope (4) to obtain rescue. The second handle (41) cooperates with the first handle (14), so that the drone can rescue multiple people who fall into the water at the same time, and the rescue efficiency is higher. Example 3

[0018] The difference between this embodiment and embodiment 1 is that: the vertical sliding plate (28) is replaced by a wide sliding plate (42), and the width of the wide sliding plate (42) is greater than the width of the vertical sliding plate (28); when in use, the contact area between the wide sliding plate (42) and the ice surface is larger, thereby improving the gliding stability of the drone during the return journey and reducing the possibility of the drone sliding back and forth or tipping over due to the slippery ice surface, causing injuries to people falling into the water and damage to the drone; The first handle (14) is provided with anti-slip grooves, which can effectively increase the gripping force between the person who falls into the water and the first handle (14), ensuring that the person who falls into the water firmly grasps the first handle (14), thereby reducing the risk of falling into the water again and the risk of falling from the mat (13) onto the ice surface during the sliding process of returning to the support platform (3); One end of the electric telescopic rod (26) is placed at the other end of the body (30) and is located above the L-shaped rope limiting plate (27). The other end of the electric telescopic rod (26) is in contact with the side surface of the other end of the L-shaped rope limiting plate (27). The other end of the pull rope (4) is sleeved on the side surface of the other end of the L-shaped rope limiting plate (27). When the drone performs ice rescue, the other end of the pull rope (4) is limited by the squeezing force between the electric telescopic rod (26) and the L-shaped rope limiting plate (27), so that the other end of the pull rope (4) is tightly fixed on the L-shaped rope limiting plate (27), thereby reducing the sliding of the other end of the pull rope (4) on the L-shaped rope limiting plate (27) and preventing the other end of the pull rope (4) from falling off the L-shaped rope limiting plate (27). There are a plurality of snow-removing saw teeth (29), and the plurality of snow-removing saw teeth (29) are arranged equidistantly along the side of the transverse sliding plate (28). When the machine body (30) slides on the ice surface via the sliding plate (28) to return to the support platform (3), there may be broken ice on the ice surface. When the transverse sliding plate (28) slides forward, the snow-removing saw teeth (29) can clear the broken ice, thereby reducing sliding resistance, so that the machine body (30) can drive the person who falls into the water to quickly return to the support platform (3), thereby improving the rescue efficiency. The pad (13) is designed to be made of a light floating body (7) with a density less than that of water, and can float on the water surface when the machine body (30) falls on the water surface to rescue a person who has fallen into the water, thereby increasing the buoyancy of the machine body (30) and providing support for the person who has fallen into the water, thereby improving the rescue efficiency; in the process of moving the person who has fallen into the water to the support platform (3), the pad (13) can prevent the person who has fallen into the water from being injured by friction caused by direct contact between the body of the person who has fallen into the water and the ice surface; The design of the storage component can store life-saving equipment such as life-saving balls and life buoys in advance in the box (18). When there are many people in the water and the drone cannot rescue them at the same time, it can provide effective support for other people in the water, thereby minimizing casualties; The driving assembly, the pull rope (4) assembly and the sliding assembly are designed to cooperate with each other. When a person who falls into the water contacts the first handle (14), the pulling force of the pull rope (4) driven by the first motor (21) and the sliding force of the slide plate (28) driven by the second motor (37) are used. The dual power can quickly move the person who falls into the water to the position of the support platform (3), thereby improving the rescue efficiency.

[0019] The purpose of the drone for ice rescue is achieved by being able to drive the drone to fly to the location where the person fell into the water through the driving component, and to drive the person who fell into the water back to the support platform (3) through the pull rope (4) component and the sliding component.
