Life-saving equipment around pond

Abstract

The invention discloses a life-saving device around a pond, comprising a base, wherein a pillar is fixed on the top surface of the base, a ceiling is fixed on the top surface of the pillar, and a cavity is provided in the ceiling. A recovery shaft is rotatably provided in the cavity, and two sets of ropes are wound around the periphery of the recovery shaft. A hanging plate is fixed on the right side of the column, and a life ring is mounted on the hanging plate. The life ring It can be tied with the rope so that when the life buoy is thrown into the water, it can be rotated by the recovery shaft to pull the life buoy back. The present invention can inflate the life buoy and oxygen mask through the rotation of the inflatable shaft. Accelerating the inflation efficiency, eliminating the need to replace the oxygen mask and life buoy back and forth, saving rescue time, meanwhile, rescuers and rescued people can be quickly pulled back to the shore by a rope at the same time, saving rescue time and energy.

1 . A lifesaving device around a pond, comprising a base, characterized in that: a column is fixed on the top surface of the base, a top plate is fixed on the top surface of the column, and an empty space is provided in the top plate. A recovery shaft is rotated in the cavity, and two sets of ropes are wound around the periphery of the recovery shaft, and a hanging plate is fixed on the right side of the column, and the hanging plate is provided with a lifebuoy. The life buoy can be tied with the rope, so that when the life buoy is thrown into the water, it can be rotated by the recovery shaft to pull the life buoy back, and a pump air box is fixed on the left side of the column, An air cavity is provided in the pump air box, and an inflation shaft is rotatably provided in the air cavity. A spiral leaf fan is arranged on the outer periphery of the inflation shaft. A hose is fixed on the top surface of the pump air box. An inflation nozzle is fixed at one end of the hose, and the hose is in communication with the air cavity. The inflation nozzle can inflate the lifebuoy. A mask cavity is provided on the top surface of the base. An inflatable tube is fixed on the left wall body, and an oxygen mask is stored in the mask cavity. There is an air intake pipe, the inflation pipe can inflate into the air intake pipe, the air cavity and the inflation pipe communicate with each other through a ventilation pipe, and a power cavity is opened in the base, and the left side of the power cavity A power motor is embedded in the side wall, and the power motor can provide power for the rotation of the inflatable shaft and the rotation of the recovery shaft.
