Water level measurement and forecast device using solar photovoltaic power generation system to supply power to water level sensor

Abstract

The invention relates to a water level measurement and forecast device using a solar photovoltaic power generation system to supply power to a water level sensor, which belongs to the technical field of new energy Internet of things. Sunlight is irradiated to solar cells mounted on a photovoltaic power generation pillar and a sun-chasing device for generating current, the current passes through a conductive wire for supplying the power to a buoyancy device, the water level sensor and a wireless transmitting antenna, when river water rises, the buoyancy device soaked in the river water relies on buoyancy for pushing the water lever sensor and the wireless transmitting antenna to slide along the edge of a water level measuring scale and further rise to the horizontal plane; when the water river falls, the water level sensor, the wireless transmitting antenna and the buoyancy device can slide along the edge of the water level measuring scale by relying on gravity and further fall to the horizontal plane. The water level sensor can convert sensed data of length changes of sliding along the edge of the water level measuring scale due to rising and falling of water level of the water river in a river bed, namely the data of the changes of the water level to electrical signals, and the electrical signals of measurement and forecast of the water level changes are sent into the air through the wireless transmitting antenna.

Description

technical field [0001] The invention relates to a water level measuring and reporting device for a solar photovoltaic power generation system to supply power to a water level sensor, and belongs to the technical field of new energy Internet of Things. Background technique [0002] In 2011, the middle and lower reaches of the Yangtze River in China, including southern Jiangsu Province, Anhui Province, Jiangxi Province, Hubei Province, and Hunan Province, suffered from spring drought. In summer, there was drought first and then flood. The water levels in many rivers, lakes, and reservoirs plummeted. It has caused many difficulties in industrial and agricultural production and people's lives. [0003] In the dry season or rainy season, the water level of the upstream, middle and downstream of a river often changes. In the past, the method of manually walking into the riverbed with a ruler to measure and record the water level was slow, difficult and inaccurate. [0004] If the...

Problems solved by technology

[0003] In the dry season or rainy season, the water level of the upper, middle and lower reaches of a river often changes. In the past, it was slow, difficult and inaccurate to measure and record the water level manually by walking into the riverbed with a ruler.

[0004] If the water level information of the upper, middle and lower reaches of the river, as well as the water level of lakes and reservoirs cannot be grasped in time, water resources cannot be allocated in a timely and effective manner. Due to global warming, extreme weather phenomena often occur, and it is impossible to continue to use the old methods in the past. Allocate water resources everywhere
