Description

Technical Field

[0001] The present invention belongs to the equipment for underwater emergency disaster reduction, and in particular relates to a closed water storage type emergency breathing device. Background Art

[0002] At present, offshore operations are becoming increasingly widespread. It is easy to occur drowning accidents when people accidentally drown while taking a boat or engaging in activities by the water. When people fall into the water and are unable to obtain oxygen supply within a short time, their lives are easily endangered. At the same time, when offshore workers need to carry out short-term underwater emergency operations, they all need equipment for underwater emergency disaster reduction; there are various existing equipment for underwater emergency disaster reduction, and the breathing device is one of them. The existing breathing device has a large load when used underwater emergently, and it is often necessary to be portable when used underwater emergently. When used for underwater emergency disaster reduction, the breathing device often floats to the water surface through a floating board. The floating board ventilates the underwater personnel through an air pipe. However, once falling into the water, when the user releases the floating board and floats upward, water often enters the breathing mask through the ventilation port of the floating board, so that the underwater personnel cannot breathe normally. Therefore, it is necessary to conveniently handle this part of the water, and thus it is necessary to upgrade and transform the structure to improve the reliability and flexibility of the structure in use. Summary of the Invention

[0003] Aiming at the deficiencies of the above-mentioned prior art, the problem solved by the present invention is: to provide a closed water storage type emergency breathing device that can be conveniently closed and drained, and is flexible and reliable in use.

[0004] To solve the above problems, the technical solutions adopted by the present invention are as follows: A closed water storage type emergency breathing device, comprising a floating board, a telescopic air pipe, a water storage cylinder, a closing assembly, and a breathing mask; a ventilation port is provided in the middle of the floating board; the inner side of the ventilation port is connected to the telescopic air pipe; the outer end of the telescopic air pipe is connected to the water storage cylinder, and the outer end of the telescopic air pipe is communicated with the inside of the water storage cylinder; the water storage cylinder is movably connected to the floating board; the middle of the outer side of the water storage cylinder is connected to the breathing mask through an opening and closing pipe; an opening and closing valve is provided on the opening and closing pipe; the closing assembly is installed on the water storage cylinder; the closing assembly includes a closing piston plate and an adjusting rod; the adjusting rod is rotatably penetrated through the water storage cylinder, the outer end of the adjusting rod extends to the outside of the upper end of the water storage cylinder, the closing piston plate is installed in the water storage cylinder and is located above the telescopic air pipe, the inner end of the adjusting rod is connected to the closing piston plate, and the adjusting rod rotates and drives the closing piston plate to move downward, and makes the closing piston plate move below the telescopic air pipe.

[0005] Furthermore, the closing assembly further includes a lifting cylinder; the lifting cylinder is slidably mounted up and down inside the water storage cylinder; a moving clamping block is provided on one side of the lifting cylinder; a strip-shaped clamping groove is provided on one side of the water storage cylinder; the lifting cylinder is slidably clamped up and down on the strip-shaped clamping groove through the moving clamping block on one side; the lower end of the lifting cylinder is connected to a closing piston plate.

[0006] Furthermore, a pressing spring is provided inside the lifting cylinder, and the upper and lower ends of the pressing spring are respectively pressed between the lower end of the adjusting rod and the lower part inside the lifting cylinder.

[0007] Furthermore, an extension rod is provided in the middle of the lower side of the closing piston plate; an expansion tube body and a connecting bottom plate are provided at the lower end of the water storage cylinder; the expansion tube body is connected around the lower end of the water storage cylinder; the lower end of the expansion tube body is hermetically installed with the connecting bottom plate; the lower end of the extension rod is connected to the middle of the upper end of the connecting bottom plate.

[0008] Furthermore, an annular sealing ring is provided on the outer sides of the four peripheries of the closing piston plate; the annular sealing ring is in sealing contact with the inner walls of the four peripheries of the water storage cylinder.

[0009] Furthermore, threaded channels are respectively provided at the two inner ends of the floating plate; assembly plates are respectively provided on the two sides of the water storage cylinder; the assembly plates are rotationally connected and positioned with the threaded channels through screwing rods.

[0011] Furthermore, the floating plate is made of a light material.

[0012] Furthermore, the breathing mask is made of a transparent material.

[0013] The beneficial effects of the present invention are as follows: When the present invention is in use, first, the floating plate and the water storage cylinder are separated, the floating plate floats on the water, and external water will enter the air vent of the floating plate during the upward floating process of the floating plate and enter the water storage cylinder through the telescopic air pipe. After the floating plate floats, the adjusting rod is rotated to drive the closing piston plate to move downward. While the closing piston plate moves downward, it drives the expansion tube body to expand downward. In this way, the water in the telescopic air pipe and the water storage cylinder will move downward. When the closing piston plate moves downward to the lower side of the telescopic air pipe, the water is thus enclosed in the lower part inside the water storage cylinder. In this way, a dry ventilation path is realized for the air vent of the floating plate, the telescopic air pipe, the upper part inside the water storage cylinder, the opening and closing pipe, and the breathing mask. Finally, opening the opening and closing valve does not affect normal ventilation, thus realizing flexible drainage and stable use. Description of the Drawings
