Photovoltaic battery assembly serving as standby power supply for medical oxygen generation system

Abstract

The invention discloses a photovoltaic battery assembly serving as a standby power supply for a medical oxygen generation system, which comprises multiple groups of frame-type solar cells and connecting pieces used for connecting and fixing the frame-type solar cells, wherein each frame-type solar cell comprises a frame and a solar cell fixedly arranged in the frame; each frame is a rectangular frame combined by four side columns, and both ends of each side column are provided with an embedding groove at the edge; each embedding groove is composed of a connecting groove and an anti-disengaginggroove; two adjacent side columns are combined into a corner, and the two connecting grooves of the two embedding grooves at the corner are communicated; the connecting pieces comprise T-shaped connecting piece with three inserting pieces and a cross-shaped connecting piece with four inserting pieces; the shape of each inserting piece is matched with that of the corresponding embedding groove, and the thickness of each inserting piece is twice of the depth of the corresponding embedding groove. The photovoltaic battery assembly is simple and convenient to assemble, can be combined and assembled into a required shape quickly and can serve as a stable and reliable standby power supply for the medical oxygen generation system.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a photovoltaic cell assembly used as a backup power source for a medical oxygen production system. Background technique [0002] The medical center oxygen production system is also called the medical molecular sieve pressure swing adsorption PSA oxygen production system. It uses molecular sieve as the adsorbent and uses ambient air as the raw material through the pressure swing adsorption method. The adsorption capacity of nitrogen (adsorbate) increases, and the adsorption capacity of nitrogen in the air decreases during decompression, forming a rapid cycle process of pressure adsorption and decompression desorption, so that oxygen and nitrogen in the air can be separated, while in the air Carbon dioxide, gaseous acids and other gaseous oxides, etc., are all substances with strong molecular polarity, and it is difficult to pass through molecular sieves, so that the p...

Problems solved by technology

[0004] Patent document CN104310315A discloses a medical center oxygen production system and its use method. The system is energy-saving and efficient, safe and reliable, easy to operate, does not require manual on-duty, and is fully automated, avoiding the production of molecular sieve powder after the oxygen generator is used for a long time. Problems such as substandard oxygen quality and insufficient flow

But there are still some deficiencies: most of the existing medical oxygen generation systems use a single line for power supply, and once the power fails, the entire oxygen generation system will collapse; so for the stable and reliable use of the system, a reliable backup power supply is also needed

However, in existing hospitals, especially old hospitals that have been established for a long time, there is not enough laying space on the roof, which limits the use of this kind of backup power supply
