Description

Technical Field

[0001] The present invention relates to a rescue device, and particularly to an underwater biomimetic life-saving device capable of carrying objects. Background Art

[0002] In recent years, safety accidents such as drowning have occurred frequently, and the data is shocking. According to the figures released by the Chinese Ministry of Health, approximately 57,000 people die from drowning in China every year, which means that more than 150 people drown every day. Due to omissions in data statistics in some areas, the World Health Organization estimates that the actual figure may be twice as high. Therefore, life-saving and rescue in water areas are very important. The problem of drowning not only accounts for a large proportion in China, but also has a significant number worldwide. According to the data of the World Health Organization, about 5 million people die from accidental injuries globally every year. Drowning accidents have caused great pain and irreparable losses to the families of the drowned. How to effectively reduce the mortality rate of drowning accidents has become a topic of common concern in the whole society.

[0003] Currently, the most common water rescue equipment is the life buoy. The life buoy has a large buoyancy and is generally suitable for rescuers to rescue the drowning person and float to the water surface, but it cannot effectively guarantee the safety of the rescuer himself during water or underwater rescue. Moreover, the rescue efficiency of the life buoy is not high, and there are certain risks in the rescue. In addition to the life buoy, other common rescue equipment such as life rafts also have the problems of low rescue efficiency and difficulty in underwater rescue, and at the same time, unnecessary rescue costs are increased. Therefore, it is very necessary to design a new type of safe and efficient life-saving device to solve the problems of low rescue efficiency, low safety guarantee coefficient of the rescuer, and inability to carry objects of the existing rescue equipment. Summary of the Invention

[0004] Based on the problems of low rescue efficiency, low safety guarantee coefficient of the rescuer, and inability to carry objects existing in the above-mentioned existing rescue equipment, and in order to solve the problems of low rescue efficiency, low safety guarantee coefficient of the rescuer, and inability to carry objects existing in the above-mentioned existing rescue equipment, the present invention proposes an underwater biomimetic life-saving device capable of carrying objects, and in order to solve the problems of low rescue efficiency, low safety guarantee coefficient of the rescuer, and inability to carry objects existing in the above-mentioned existing rescue equipment, the following technical solutions are proposed:

[0005] The present invention provides an underwater biomimetic life-saving device capable of carrying objects. The underwater biomimetic life-saving device capable of carrying objects includes a thruster, a control button, a fuselage, and a load-carrying box. The control button is used to convert and control the lifting or advancing of the thruster. The thruster includes at least one lifting thruster and at least one advancing thruster. The lifting thruster is connected to the fuselage through a lifting link, and the advancing thruster is connected to the fuselage through an advancing link. A load-carrying box is arranged on the fuselage, and an inflatable airbag is arranged in the load-carrying box.

[0006] Further, the fuselage includes a housing, a power supply, a controller, a driver, and a motor. An accommodation chamber for arranging the power supply, the driver, the controller, and the motor is provided inside the housing. The power supply is respectively connected to the controller and the driver. The input end of the controller is connected to the control button, the output end of the controller is connected to the driver, and the output end of the driver is connected to the input end of the motor.

[0007] Further, the thruster includes a housing, a propeller, and an end cap. The propeller is installed inside the housing. The end cap is connected to the end of the housing. And the lifting thruster is fixedly connected to the lifting link, and the traveling thruster is fixedly connected to the traveling link.

[0008] Further, a suspension, an anti-detachment bracelet, and a middle handrail are provided on the fuselage.

[0009] Further, the thruster includes a first lifting thruster, a second lifting thruster, a first traveling thruster, and a second traveling thruster. The first lifting thruster is connected to the fuselage through a first lifting link, the second lifting thruster is connected to the fuselage through a second lifting link, the first traveling thruster is connected to the fuselage through a first traveling link, and the second traveling thruster is connected to the fuselage through a second traveling link. And control buttons are respectively arranged on the first lifting link and the second lifting link.

[0010] Further, the control buttons include a traveling control button and a lifting control button. The traveling control button controls the rotation direction and speed of the first traveling thruster and the second traveling thruster. The lifting control button controls the rotation direction and speed of the first lifting thruster and the second lifting thruster.

[0011] Further, the first lifting link and the second lifting link are arranged horizontally opposite to each other, and the first traveling link and the second traveling link are in a V shape.

[0012] Further, the fuselage and the load box are connected by fixing fasteners.

[0013] Further, the load box includes a main part and a cover body. A W-shaped sealing ring is arranged at the connection between the main part and the cover body.

[0014] Further, the shape of the propeller blade adopts a dolphin fin-shaped streamline.

[0015] The beneficial effects of the present invention are mainly manifested in:

[0016] 1. The underwater bionic life-saving device capable of carrying objects is arranged in a "big" shape as a whole. The fuselage, the lifting thrusters and the traveling thrusters are symmetrically distributed on the same horizontal plane. It has small overall size and volume, is portable and lightweight, and is convenient to operate. It can perform multi-directional rescue operations on the drowning person, greatly improving the rescue efficiency and success rate, and reducing unnecessary rescue costs.

[0017] 2. The underwater bionic life-saving device capable of carrying objects uses multiple lifting thrusters and traveling thrusters in combination to achieve fast and effective underwater rescue. It can shorten the search, arrival and floating time of the rescuer, effectively reduce the physical exertion of the rescuer. In addition, the settings of auxiliary devices such as the load-carrying box and the anti-detachment bracelet of the life-saving device can further strengthen the safety guarantee of the underwater and water rescuers and the drowning person. The internal airbag of the load-carrying box makes it difficult for the drowning person to sink again after floating to the water surface in the later stage of the rescue, reducing the rescue risk. Thus, while ensuring the safety of the rescuer's life, it can, to a certain extent, guarantee the life safety of the drowning person with vital signs.

[0018] 3. The first lifting thruster and the second lifting thruster of the underwater bionic life-saving device capable of carrying objects are arranged in a V shape on the same plane. While ensuring that the load-bearing and climbing force of the life-saving device are sufficient, it cancels the horizontal forces on both sides. The life-saving device can still maintain a self-balanced state in the single-handed detachment state. Moreover, the rotation direction and rotation speed of the lifting thrusters and the traveling thrusters can be set, and it can flexibly and freely achieve turning and variable-speed movement, ensuring convenient operation and improved rescue effect when the rescue difficulty is high or the drowning person loses the ability to move by himself. At the same time, the lifting thrusters and the traveling thrusters adopt propeller blades with streamline shapes imitating dolphin flippers, further increasing the traveling speed and rescue efficiency of the life-saving device and reducing the operating noise.

Detailed implementation manners

[0026] The following combines Figures 1-6 with the detailed implementation manners to further describe the present invention.

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present invention can be applied to other implementation schemes, variation schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the present invention.

[0028] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationships indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above - mentioned terms should not be construed as limiting the present invention.

[0029] The present invention provides a load-carrying underwater bionic life-saving device, which includes a thruster 2, a control button 5, a fuselage 3 and a load-carrying box 1. The control button 5 is used to convert and control the lifting or traveling of the thruster 2. The thruster 2 includes at least one lifting thruster 21 and at least one traveling thruster 22. The lifting thruster 21 is connected to the fuselage 3 through a lifting connecting rod 3A, and the traveling thruster 22 is connected to the fuselage 3 through a traveling connecting rod 3B. Rescuers can use the control button 5 to control the speed and direction of the lifting thruster 21 and the traveling thruster 22 according to the actual situation, so as to realize the forward movement, diving and floating of the life-saving device, speed up the rescue process and improve the rescue efficiency. A load-carrying box 1 is arranged on the fuselage 3, and an inflatable airbag is arranged in the load-carrying box 1, which is convenient to ensure the safety of the rescuer himself, so that the person falling into the water will not sink into the water again when being rescued out of the water surface, and improve the safety guarantee coefficient of the rescuer and the person falling into the water. Further, the connection methods between the lifting connecting rod 3A and the traveling connecting rod 3B and the fuselage 3 include but are not limited to welding, such as bonding, etc. The setting of the control button 5 can adjust the rotation speed and rotation direction of the propeller 213 to achieve different propulsion speeds. It is worth mentioning that the rotation speed of the propeller 213 is realized by the controller controlling the rotation speed of the motor, and the rotation direction is realized by the rotation direction of the propeller 213.

[0030] Further, the fuselage 3 includes a housing, a power supply, a controller, a driver and a motor. The housing has an accommodation chamber for arranging the power supply, the driver, the controller and the motor, as Figure 6As shown in the figure, the power supply is respectively connected to the controller and the driver. The input end of the controller is connected to the control button 5, the output end of the controller is connected to the driver, and the output end of the driver is connected to the input end of the motor. Specifically, adjusting the switch of the control button 5 transmits signals (k1, k2, k3, k4) to the controller. The controller (by programming, defining the direction bit and the control bit, with control bit 1 for motor start, control bit 0 for motor stop, direction bit 0 for forward motor rotation, and direction bit 1 for reverse motor rotation) is connected to the signal input end of the motor driver. The controller and the driver are respectively connected to the power supply. The output end of the driver is connected to motors M1 and M2, and motors M1 and M2 start to operate synchronously, driving the propeller 213 to work. In this embodiment of the present invention, the power supply uses a lithium battery, the controller uses the STM32 model, the driver uses the L298N model, and the motor uses a small DC motor. In addition, the synchronous reverse rotation, synchronous forward rotation, and reverse rotation of the motors control the rotation direction of the propeller 213, thereby controlling the lifting, advancing, or turning of the load-carrying underwater bionic life-saving device. Specifically, the motor is connected to the first connecting rod through a coupling. The first connecting rod is rotationally connected to other connecting rod shafts. The rotation of the motor causes the connecting rod to make a reciprocating motion for transmitting the rotational force of the motor. The connecting rod connected to the propeller 213 converts the reciprocating motion into a rotational motion. Here, the propeller 213 undertakes the work of the crank, forming a crank-connecting rod mechanism, and making the propeller 213 rotate using the principle of the connecting rod and crank. Of course, a gear transmission method can also be used to enable the propeller 213 to achieve the rotation function.

[0031] In one embodiment, the thruster 2 includes a housing 211, a propeller 213, and an end cap 212. The propeller 213 is installed in the housing 211. The end cap 212 is connected to the end of the housing 211, and the lifting thruster 21 is fixedly connected to the lifting connecting rod 3A, and the advancing thruster 22 is fixedly connected to the advancing connecting rod 3B. The fixed connection method here is integral injection molding or welding between the two, but is not limited to these two connection methods. In this embodiment, under the control of the motor in the fuselage 3 of the load-carrying underwater bionic life-saving device, the propeller 213 rotates in the housing 211, so that the entire load-carrying underwater bionic life-saving device makes lifting, advancing, or turning movements longitudinally or transversely.

[0032] Specifically, the connection method between the end cap 212 and the housing 211 includes but is not limited to threaded connection, such as sealed plug-in connection.

[0033] Further, a suspension 4, an anti-detachment bracelet 6 and a middle armrest 7 are provided on the fuselage 3. The suspension 4 can hold lighting equipment or imaging devices such as GoPro cameras, facilitating the rescuer to observe the situation ahead and shoot the rescue process. Specifically, the suspension 4 is provided at any position on the fuselage 3 suitable for hanging lighting equipment or imaging devices. In this embodiment of the present invention, the suspension 4 is provided at the lower part of the fuselage 3. The suspension 4 is fixedly connected to the lower part of the fuselage 3, and the fixed connection method includes but is not limited to welding. The anti-detachment bracelet 6 can ensure the safety of the rescuer. In one embodiment, the anti-detachment bracelet 6 is connected to one end of a light rope, and the other end of the light rope is connected to the bottom of the middle armrest 7, such as a loop connection. The middle armrest 7 facilitates the rescuer or the person falling into the water to grip.

[0034] Further, an inflatable airbag is provided in the load box 1 for use by the rescuer and the person falling into the water after surfacing during the later stage of the rescue, so as not to sink into the water again, improving the safety factor of the rescuer and the person falling into the water. It is worth mentioning that the inflatable airbag is placed in the load box 1. Driven by this life-saving device, the rescuer pulls the person falling into the water to the water surface. The rescuer can take out the inflatable airbag from the load box 1 according to the actual rescue situation and use it for the person falling into the water, acting as a life buoy, playing the role of preventing the person falling into the water from sinking again and appropriately reducing the burden on the rescuer. In this embodiment of the present invention, the inflatable airbag is a pre-inflated airbag. In one embodiment, the inflatable airbag is connected to one end of a light rope, and the other end of the light rope is connected to the bottom of the load box 1, such as a loop connection, to prevent the inflatable airbag from being too far away from the entire life-saving device.

[0035] Further, the thruster 2 includes a first lifting thruster 2A, a second lifting thruster 2B, a first traveling thruster 2C and a second traveling thruster 2D. The first lifting thruster 2A is connected to the fuselage 3 through a first lifting link 3A1, the second lifting thruster 2B is connected to the fuselage 3 through a second lifting link 3A2, the first traveling thruster 2C is connected to the fuselage 3 through a first traveling link 3A3, and the second traveling thruster 2D is connected to the fuselage 3 through a second traveling link 3A4. And control buttons 5 are respectively provided on the first lifting link 3A1 and the second lifting link 3A2. More specifically, the first lifting thruster 2A, the second lifting thruster 2B, the first traveling thruster 2C and the second traveling thruster 2D are respectively hinged to the first lifting link 3A1, the second lifting link 3A2, the first traveling link 3A3 and the second traveling link 3A4. The first lifting link 3A1, the second lifting link 3A2, the first traveling link 3A3 and the second traveling link 3A4 are welded to the fuselage 3, but the connection method is not limited to this.

[0036] Further, the control button 5 includes a travel control button 5A and a lift control button 5B. The travel control button 5A controls the rotation direction and speed of the first travel thruster 2C and the second travel thruster 2D, and the lift control button 5B controls the rotation direction and speed of the first lift thruster 2A and the second lift thruster 2B. It should be noted that the travel control button 5A and the lift control button 5B are sub-buttons of the control button, respectively corresponding to controlling travel and lift. Control buttons 5 are provided on both the first lift link 3A1 and the second lift link 3A2, and the control buttons 5 on the lift links 3A on both sides have the same function and the same effect. The setting of the sub-buttons in the control button facilitates the rescuer to select the control button 5 on the nearby lift link 3A for lift or travel control based on the actual situation and the convenience of operation.

[0037] Further, the first lift link 3A1 and the second lift link 3A2 are arranged horizontally opposite to each other, and the first travel link 3A3 and the second travel link 3A4 are in a V shape, which conforms to the lift and travel design of the life-saving device. Specifically, the angle between the first travel link 3A3 and the second travel link 3A4 is 90 degrees.

[0038] Further, the first lift thruster 2A and the second lift thruster 2B are in a V shape. While ensuring that the load capacity and climbing force of the life-saving device are sufficient, it offsets the horizontal forces on both sides, can enhance the anti-interference and self-balancing capabilities of the life-saving device to a certain extent, and still can be flexibly operated and improve the rescue effect in complex rescue situations.

[0039] Further, the fuselage 3 and the load box 1 are connected by a fixing fastener 31. Specifically, the fuselage 3 integrally extends the fixing fastener 31, the fixing fastener 31 is a buckle, the bottom of the load box 1 has a buckle groove, and the load box 1 is snap-connected to the fuselage 3, but is not limited to this connection method.

[0040] Further, the load box 1 includes a main part 11 and a cover 12, and a W-shaped sealing ring is provided at the connection between the main part 11 and the cover 12. Using a W-shaped sealing ring for sealing, compared with ordinary rectangular sealing rings and O-shaped sealing rings, under the action of the same external pressure, the W-shaped sealing ring can withstand a higher pre-tightening load.

[0041] Further, the blade shape of the propeller 213 adopts a dolphin fin-like streamline. According to the bionics principle, it reduces the flow resistance of the blade of the propeller 213, greatly improves the propulsion efficiency, and at the same time has good noise prevention performance.

[0042] The working principle of the present invention is as follows:

[0043] In the working state, when a drowning person is found, the rescuer turns on the power to start the load-carrying underwater bionic life-saving device, holds the lifting connecting rod 3A with both hands, enters the water, presses any one of the forward control buttons 5A on the left and right sides of the lifting connecting rod 3A, sets the rotation direction and speed, and the propellers 213 of the first forward thruster 2C and the propellers of the second forward thruster 2D start to rotate. When the first forward thruster 2C and the second forward thruster 2D rotate in opposite directions, the torsional moments generated by the two sets of propellers are balanced, and the load-carrying underwater bionic life-saving device provides a stable forward propulsion force to drive the rescuer closer to the drowning person. After the rescuer approaches the drowning person, the rescuer hugs the drowning person from behind, then presses any one of the lifting control buttons 5B on the left and right sides of the lifting connecting rod 3A, sets the rotation direction and speed, and the bolts of the first lifting thruster 2A and the bolts of the second lifting thruster 2B start to rotate. When the first lifting thruster 2A and the second lifting thruster 2B rotate in opposite directions, the load-carrying underwater bionic life-saving device provides a stable upward propulsion force to quickly drive the rescuer and the drowning person to float to the water surface. At this time, the rescuer can take out the inflatable airbag in the load-carrying box body 1 and put it on the drowning person to prevent him from sinking into the water again.

[0044] In addition, when the first lifting thruster 2A and the second lifting thruster 2B turn in the same direction, flexible turning motion can be performed in the horizontal direction. When the first forward thruster 2C and the second forward thruster 2D turn in the same direction, flexible turning motion can be performed in the vertical direction.

[0045] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. When the functions and structural principles of the present invention have been demonstrated and explained in the embodiments, the embodiments of the present invention can be deformed or modified in any way.
