A reservoir dam with heat exchange function

Abstract

The invention provides a reservoir dam with the heat exchange function. The reservoir dam comprises a reinforced concrete dam body. A heat exchanger is buried in the reinforced concrete dam body and is further connected with an energy storing device. A water inlet pipeline and a water outlet pipeline are arranged at the two ends of the heat exchanger correspondingly. A centrifugal pump is arrangedat the position of the water inlet pipeline, and a temperature sensor is arranged at the position of the water outlet pipeline. The reservoir dam further comprises a first controller. The first controller is sequentially connected with a permanent magnet synchronous servo motor, the centrifugal pump and the heat exchanger. The temperature sensor is connected with the controller and transmits thedetected temperature value at the position of the water outlet pipeline to the first controller, and the first controller conducts fuzzy PID control on the flow amount of the centrifugal pump to forma major loop, so that the temperature is used for controlling the flow amount. The permanent magnet synchronous servo motor feeds the rotating speed back into the controller so as to form a minor loop, so that the rotating speed is used for controlling the flow amount. Control is made more accurate and sufficient and hydraulic power in a reservoir is effectively utilized.

Description

technical field [0001] The invention relates to the technical field of reservoir dams, in particular to a reservoir dam with heat exchange function. Background technique [0002] Reservoirs are water conservancy engineering structures used to retain flood water and regulate water flow, and can be used for irrigation, power generation, flood control and fish farming. But the water source in the reservoir has a certain temperature, and the water energy temperature of the water source itself is not fully utilized in the prior art. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a reservoir dam with heat exchange function, in which a heater is embedded in the reinforced concrete dam, and the water energy of the water source in the reservoir is fully utilized. [0004] A reservoir dam with heat exchange function provided by the present invention comprises a reinforced concrete dam, a heat exchanger is embedded in the re...
