Description

Technical Field

[0001] The present application relates to the field of drowning prevention and rescue technology, and in particular to a pressure-sensitive life-saving brick for drowning prevention in urban rivers. Background Art

[0002] Due to the special location of urban rivers, there are often a large number of residential areas around them, with a large number of people, and the probability of drowning accidents is high. At the same time, due to the limited use of urban land, rivers often use vertical retaining walls. When people accidentally fall into the river, it is often difficult for them to return to the shore by their own strength, which further increases the risk of drowning. Therefore, implementing safety training and safety warning measures for drowning prevention in rivers, and developing new life-saving technologies and equipment are of great significance to protecting the lives and property of the people.

[0003] At present, most urban rivers use lifebuoys placed on the river guardrails, but when a person falls into the water, if there are no other people around, the lifebuoy cannot be used. In the prior art, lifesaving devices mostly use automatically inflatable air bags, which are worn around the waist or arms, but such devices need to be equipped in advance, and drowning is often an accident, so the possibility of wearing a lifesaving device is small. Therefore, a lifesaving device that does not need to be worn, can be combined with facilities around the river, and is easy to use is needed. Summary of the invention

[0004] The purpose of the embodiment of the present application is to provide a pressure-sensitive life-saving brick for preventing drowning in urban rivers, which is installed on upright retaining walls or other types of embankment and revetment in urban rivers, and adopts a method of releasing a lifebuoy by pressure sensing. When a person accidentally falls into the water, he or she can follow the instructions of the warning slogan on the pressure-sensitive life-saving brick and slap the pressure-sensitive life-saving brick hard. The lifebuoy will be quickly inflated and expanded in a very short time and pop out after breaking through the outer shell, thereby effectively providing rescue for the drowning person, solving the shortcomings of existing life-saving devices such as the need for advance preparation and complicated operation.

The lifebuoy compression package 1 is wrapped with a shell 2 on the outside and has an air inlet 4, which is fixed to the pressure-sensitive life-saving brick body 5 through a buckle 3; the buckle 3 is fixedly connected to the upper cover plate 6, and a rubber sealing ring is arranged on the edge of the upper cover plate 6, which is installed on the front of the pressure-sensitive life-saving brick body 5 through screws; the bottom plate 7 is located on the back of the pressure-sensitive life-saving brick body 5 and is fixedly connected to the pressure-sensitive life-saving brick body 5; the front of the pressure-sensitive life-saving brick body 5 is printed with a warning slogan 16: "Anti-drowning life-saving device, lifebuoy can be ejected by slapping hard, please do not use it in non-emergency situations".

[0025] The control circuit 9 is located inside the pressure-sensitive life-saving brick body 5, and the control circuit 9 is fixed to the inner side of the bottom plate 7 by screws; there is a pressure sensor 13 on the control circuit 8, and the top of the pressure sensor 13 passes through the through hole of the upper cover plate 6 and protrudes about 1 cm, contacting the outer shell 2; there is a rubber sealing ring between the top of the pressure sensor 13 and the through hole of the upper cover plate 6 for waterproofing.

[0026] The battery 14 is located inside the pressure-sensitive life-saving brick body 5, fixed to the inner side of the base plate 7 by screws, and connected to the control circuit 8 through the power supply line 15; the gas generator 10 is located inside the pressure-sensitive life-saving brick body 5, fixed to the inner side of the base plate 7 by screws, and connected to the control circuit 8 through the signal transmission line 9, and includes a gas cylinder and an air outlet; the front end of the inflation tube 11 is fixedly connected to the air outlet of the gas generator 10, and the end is provided with a nozzle 12, which is connected to the air inlet 4. The air inlet 4 has a one-way valve. When the lifebuoy compression bag 1 is inflated, popped out and released, the one-way valve is in a closed state to ensure that the gas in the lifebuoy will not leak.

[0027] The life buoy compression bag 1 is made of nylon cloth, the outer shell 2 is made of PP material and is red in color, the pressure-sensitive life-saving brick body 5, the upper cover plate 6 and the bottom plate 7 are made of stainless steel, and the warning slogan 16 is laser engraved.

[0028] The pressure-sensitive life-saving brick body 5 is a sealed waterproof structure. A groove is set on the upright retaining wall 17 of the urban river, and the pressure-sensitive life-saving brick body 5 is installed in the groove. The installation height is about 0.2m above the normal water level. During the flood season, the installation height is adjusted to about 0.2m above the flood season water level, and the installation spacing is 5 to 10m; the upper cover plate 6 is opened regularly to inspect and replace the gas cylinder and battery 14 of the gas generator 10. When the pressure-sensitive life-saving brick is used, the lifebuoy compression bag 1 and the shell 2 are replaced.

[0029] Working principle: The pressure-sensitive life-saving brick for preventing drowning in urban rivers is suitable for upright retaining walls or other types of embankment and revetment in urban rivers. It mainly comprises a life buoy compression bag 1 and a pressure-sensitive life-saving brick body 5. The life buoy compression bag 1 is fixed on the pressure-sensitive life-saving brick body 5. The pressure-sensitive life-saving brick body 5 is installed on the upright retaining wall 17 or other types of embankment and revetment in urban rivers. A conspicuous warning slogan 16 is printed on the front of the pressure-sensitive life-saving brick body 5: "Anti-drowning life-saving device, life buoy can be ejected by slapping it hard, please do not use it in non-emergency situations"; when someone accidentally falls into the water, the pressure-sensitive life-saving brick can be easily found and understood. The warning sign 16 on the brick body 5 is slapped hard on the red shell 2 below the warning sign 16 as instructed, and the pressure is transmitted to the pressure sensor 13 below the shell 2. The pressure sensor 13 generates an electrical signal after being subjected to the pressure and sends it to the control circuit 8. After receiving the electrical signal sent by the pressure sensor 13, the control circuit 8 immediately sends a start signal to the gas generator 10 through the signal transmission line 9. After receiving the start signal, the gas generator 10 opens the gas cylinder, and a large amount of gas generated enters the lifebuoy compression bag 1 through the inflation pipe 11, so that the lifebuoy compression bag 1 is quickly inflated and expanded in a very short time and pops out after breaking through the shell 2.

[0030] By installing on upright retaining walls or other types of embankment protection banks in urban rivers and setting eye-catching and easy-to-understand warning signs, people who accidentally fall into the water can clap to release the lifebuoy according to the instructions. The operation is simple and convenient, and the response speed is fast. It provides self-rescue tools for people who fall into the water and effectively protects their lives.

[0031] The invention has the advantages of simple structure, low cost, convenient maintenance, various installation methods, and can be combined with urban river embankment and bank protection, thus having high practicality and popularization and application value.

[0032] The above description is only an embodiment of the present application and is not intended to limit the scope of protection of the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
