Water flow direction fixing pipeline hydroelectric module and system and power generation method

Abstract

The invention discloses a water flow direction fixing pipeline hydroelectric module and a system and a power generation method, and belongs to the field of fluid dynamics. The water flow direction fixing pipeline hydroelectric module is characterized in that the water flow direction fixing pipeline hydroelectric module comprises a swinging following pipe, a power generation assembly (permanent magnets / coils or pressing rods / piezoelectric modules), a semi-flexible supporting member (elastic bellows or spring structures or annular double magnet structures with the same polarity being arranged upand down) and a fixing base provided with mounting holes. According to the water flow direction fixing pipeline hydroelectric module and the system and the power generation method, since water flow flows through a barrier to form eddy behind the barrier, the disturbance of the eddy causes the swinging following pipe to swing left and right following the semi-flexible supporting member at the lower part, and relative motion occurs between a fixed member and a moving following member of the power generation assembly inside to carry out power generation. The water flow direction fixing pipelinehydroelectric module and the system and the power generation method has the advantages that the whole system does not need lubrication and maintenance, moving members do not exist, the service life islong, maintenance is not needed, and the sealing problem of a rotating element does not exist.

Description

technical field [0001] The invention relates to a pipeline hydroelectric power generation module and system and a power generation method for constant water flow direction, which belong to the field of fluid dynamics. Background technique [0002] The energy generated during the flow of water bodies in nature is called hydropower, and an important application of hydropower is hydropower generation. Hydroelectric power generation is to generate electricity by using the energy generated when water in rivers and lakes flows through terrains of different heights. The current hydroelectric power generation is achieved by the water turbine and generator in the hydroelectric generating set to realize the secondary conversion of water potential energy to mechanical energy and then to electrical energy. conversion achieved. According to the size of the installed capacity of hydropower stations, they can be divided into large, medium and small hydropower stations, and the current sma...

AI Technical Summary

Problems solved by technology

According to the size of the installed capacity of hydropower stations, they can be divided into large, medium and small hydropower stations, and the current small hydropower stations have relatively high cost per unit of installed capacity due to small-scale power production.

In addition, general hydroelectric power generation uses concentrated water head to guide high-speed water flow to impact the water turbine to drive the generator to generate electricity. Due to the existence of moving parts, regular maintenance of the entire system cannot be avoided, and the required cost is relatively high.
