Detailed Description
The invention is explained in more detail below with reference to the figures and examples.
Example one
As shown in fig. 1-3: an intelligent inflatable life jacket for underwater rescue comprises a jacket body 1, wherein the jacket body 1 is worn on the upper body of a rescuer. The clothes body 1 is composed of a front baffle plate 01 and a rear baffle plate 02 which are connected with each other through a connecting rope 11, and the thickness of the clothes body 1 can be adjusted to be fastened on the body of a user.
The top of the clothes body 1 is connected with an adjusting rope 5, the free end of the adjusting rope 5 is provided with a plurality of buckles 6, and the buckles 6 are arranged at intervals along the length direction. A clamping groove 7 matched with the buckle 6 is formed in one side, far away from the clothes body 1, and the thickness of the clothes body 1 (namely the distance between the front separation blade 01 and the rear separation blade 02) is adjusted through clamping of bayonets and the clamping groove 7 at different positions. Wherein the adjusting ropes 5 are provided with a plurality of ropes, so that the body of the user can be fastened more stably when the clothes body 1 is used.
The outer sides of the front baffle piece 01 and the rear baffle piece 02 of the clothes body 1 are respectively provided with an air bag 2, the positions of the front baffle piece 01 and the rear baffle piece 02 are respectively provided with an inflating component 3, and the air bags 2 at the corresponding positions wrap and seal the inflating components 3.
The air bag 2 is provided with the air release valve 4, so that a rescuer can release the air in the air bag 2 by opening the air outlet valve after air is ventilated in an upward floating manner, and can continue to dive and salvage a person falling into the water.
The inflatable member 3 includes a plurality of housing shelves 31, and the plurality of housing shelves 31 are provided with a gas generating agent 32 therein. The outer side of each containing frame 31 is hinged with a sealing plug, and the air bag 2 completely wraps all the containing frames 31.
The air bag 2 is made of a fabric consisting of polyether TPU and high-strength polyamide. The preparation method of the fabric comprises the following steps: the polyether type TPU is stuck on the high-strength nylon by a primer coating method. The primer coating is to spray a binder on the high-strength nylon and then paste polyether TPU.
Example two
As shown in the attached drawing 4, because the air bag 2 of the scheme is used for rescuing in diving, the air bag needs to be inflated by the inflating component 3 in a short time to float upwards, so that the hidden danger of excessively extruding the body of a rescuer exists, and further, the front blocking piece 01 and the rear blocking piece 02 are both made of hard metal, and meanwhile, the connecting rope 11 between the front blocking piece 01 and the rear blocking piece 02 is supported by the metal block 10, so that the whole supporting barrier is formed for the body of the rescuer. Meanwhile, the front retaining piece 01 and the rear retaining piece 02 are made of metal materials, so that rescuers can sink and rescue quickly.
Wherein the front baffle plate 01 and the rear baffle plate 02 are matched with the size of the corresponding air bag 2.
This scheme all sets up gasbag 2 on preceding separation blade 01 and back separation blade 02, and the main objective can float out of the water surface at whole head homoenergetic under the state of not having an effect after for the rescuer come-up.
In the further design, after the body of a rescuer is groped for a period of time underwater, the body of the rescuer is relatively weak, particularly, the sensitivity of the body function is extremely reduced in winter, the underwater environment is relatively dark, the trigger switch of the inflatable part 3 on the clothes body 1 cannot be quickly and manually triggered, and the rescuer is in subconscious body safety consideration and can mostly retain greater energy to grope the switch and float up for ventilation, so that the rescue efficiency is relatively reduced. Meanwhile, after the underwater is cold in winter for a period of time, the potential safety hazard that the body part loses consciousness and the like and cannot quickly float upwards or quickly trigger the trigger switch of the inflatable component 3 exists. Therefore, the scheme further provides an automatic induction module to ensure the life safety of rescuers.
Specifically, change conventional trigger switch into touch-control formula to locate the clothing body 1 chest side, the rescuer accessible is patted (pat can), receiving the light back of patting, trigger switch carries out quick aerate to gasbag 2 promptly, makes trigger switch be convenient for more realize, does benefit to the environment of rescue under water.
After the trigger switch is turned on, the ignition switch leads the gas generating agent 32 (the ignition and inflation setting belongs to the existing mature technology and is not an improvement point of the scheme), and after the trigger switch is turned on, the sealing plug is opened, then the air bag 2 is inflated and expanded, and the rescuers are driven to float. After floating, the floating is realized by continuing diving and opening the air outlet valve to deflate.
The containing frame 31 provided with the plurality of gas generating agents 32 can float upwards circularly and repeatedly, so that rescuers can dive and salvage for multiple times, and then the success probability of salvage is improved.
Secondly, an external member structure 8 and an induction element which is connected with the external member structure 8 and actively identifies whether the rescuer is safe or not in real time are additionally arranged. When the danger of the rescuers is confirmed, the switch is automatically triggered to rapidly inflate the air bag 2.
The sensing element comprises a miniature pressure sensor 9 and a controller (waterproof treatment is needed) which are used conventionally, and the pressure sensor 9 is electrically connected with the controller. The controller is electrically connected with the touch switch to actively control the touch switch to be turned on.
The controller is a small PLC controller, and can adopt a Native BACnet series CP-SPC model.
Referring to figure 5, the plc controller is arranged to receive pressure from the elbow and knee pressure sensor 9 for a 3 second pause, and over 3 seconds to trigger the switch to rapidly inflate the air-bag 2. The intermittence time needs the time that the pressure sensors 9 at the elbow and the knee are not stressed synchronously, and if one of the pressure sensors 9 is still stressed, the controller does not trigger the switch. Specifically, the intermittent time is not necessarily about 3 seconds, and the temperature during rescue, the physical condition of the rescuer, and the like can be specifically seen for adjustment.
The design has the starting point that when a rescuer dives into water to salvage, the whole body of the rescuer can swing, the whole movement in the water mainly depends on the arm and the leg, so that when the elbow and the knee are static simultaneously, the rescuer can be defaulted to gradually lose consciousness basically, and an automatic induction module is arranged to play a role in ensuring the safety of the rescuer.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the description, and the protection scope must be determined by the scope of the claims.
