Pressure underwater diving self-rescue device

Abstract

The invention relates to the technical field of rescue equipment and in particular to a pressure underwater diving self-rescue device which is capable of extruding or releasing an airbag, preventing the situation that a threaded tube is not completely rotated by a diver and maintaining life safety, and is relatively high in practicability, in addition, a user can be effectively assisted, the device is applicable to users of multiple body types and is relatively low in use limit, and thus the use reliability of the device is improved. The pressure underwater diving self-rescue device comprisesan airbag, an air supply floater, a fixing rack, a threaded rod, a threaded tube, a clamping plate, a communicating hose as well as a first partition plate, a second partition plate, a servo motor, arotating roller, a transmission belt, a baffle cover, a cylinder, a driving motor, stirring blades and a sealing plate, wherein the top end of the communicating hose is communicated with the bottom end of the air supply floater; the servo motor is mounted on the bottom wall of a groove; a transmission shaft is arranged at the output end of the left side of the servo motor; the transmission shaft is sleeved by the rotating roller; a driving shaft is arranged at the output end of the bottom of the driving motor; the stirring blades are arranged on the driving shaft.

Description

technical field [0001] The invention relates to the technical field of rescue equipment, in particular to a pressure diving self-rescue device. Background technique [0002] As we all know, the pressure diving self-rescue device is a device that helps divers return to the surface in a short period of time when they encounter unexpected situations such as drowning when diving underwater, so as to ensure that divers can breathe in time to relieve physical discomfort. , so as to ensure the safety of divers, it is widely used in daily small-scale diving activities; the existing pressure diving self-rescue device includes air bags, air supply floats, fixed mounts, threaded rods, threaded pipes, splints and connecting hoses, The air supply float is umbrella-shaped, the top end of the communication hose communicates with the bottom end of the air supply float, a groove is arranged on the fixed frame, and the left end of the threaded rod is connected with the left side wall of the g...

[0002] As we all know, the pressure diving self-rescue device is a device that helps divers return to the surface in a short period of time when they encounter unexpected situations such as drowning when diving underwater, so as to ensure that divers can breathe in time to relieve physical discomfort. , so as to ensure the safety of divers, it is widely used in daily small-scale diving activities; the existing pressure diving self-rescue device includes air bags, air supply floats, fixed mounts, threaded rods, threaded pipes, splints and connecting hoses, The air supply float is umbrella-shaped, the top end of the communication hose communicates with the bottom end of the air supply float, a groove is arranged on the fixed frame, and the left end of the threaded rod is connected with the left side wall of the groove. The right end of the threaded rod is inserted and screwed into the left end of the threaded pipe, a placement groove is provided on the left side wall of the support plate, and a ball bearing is arranged in the placement groove, and the right end of the threaded pipe is inserted into the ball bearing Inside, the airbag is provided with a cavity, and the bottom end of the connecting hose passes through the fixing frame and communicates with the airbag; when this pressure diving self-rescue device is in use, the diver rotates the threaded tube to adjust the distance between the support plate and the side wall of the groove. The distance between the splints, so that the splints can squeeze the airbags. The diver holds the fixed frame in his hand and dives into the water. In an emergency, the diver rotates the threaded tube to release the splints from decompressing the airbags, and the elastic deformation of the airbags returns to normal. form, to inhale gas from above the water level, thereby generating buoyancy to drive divers to float up to the water level to achieve self-rescue effect; Subject to certain restrictions, it is easy to cause the diver to rotate the threaded pipe incompletely, which is easy to pose a threat to the life safety of the diver, and the practicability is low; and it cannot assist the user, cannot adapt to users of various sizes, and has limitations in use Higher, resulting in lower reliability of its use
