Lighting and guiding display method and device for generating power by utilizing discharge water in water tank of building

Abstract

The invention relates to a lighting and guiding display method and device for generating power by utilizing discharge water in a water tank of a building, wherein a generator is installed on the water pipe and fire-prevention water pipe of the building; and the water flow which is generated in the water pipe in the course of utilizing the water drives the generator to generate electricity. The concrete device provided by the invention comprises a hydroelectric generating device, an energy storing device and a lighting device, wherein the hydroelectric generating device is arranged on the water pipe at the lower part of the water tank and is composed of the generator, a first permanent magnet and an impeller; the generator is arranged outside the water pipe; the first permanent magnet is arranged on the input shaft of the generator; the impeller is arranged in the water pipe through a rotating shaft; a second permanent magnet is arranged in the impeller; the power output end of the generator is connected with the energy storing device; and the energy storing device is connected with the lighting device. In the invention, the water flow in the water pipe drives the impeller to rotate; the current is generated by the generator; and the current is output to the energy storing device and used for the lighting and guiding display for escape or public passages. When the building is on fire, a power grid is interrupted. The device provided by the invention continuously generates electricity and independently supplies the lighting and guiding display to the energy storing device by means of the water flow, and is not influenced by the power grid.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to a hydroelectric power generation device, in particular to a method and device for lighting and guiding and displaying electricity generated by using water discharged from a water tank in a building. Background technique: [0002] When a fire breaks out in a high-rise building, the power supply will be interrupted, the indoor lighting and guidance display will be lost, and it will be difficult for people in the building to identify the escape direction and route. Invention content: [0003] The object of the present invention is to provide a lighting and guidance display method that utilizes the water released from the water tank of a building to generate electricity. The lighting and guidance display method that utilizes the water discharged from the water tank of a building to generate electricity should solve the problem of building fires in the prior art. After the emergency, the pow...
