Description

Technical Field

[0001] This utility model relates to the field of new energy supporting equipment technology, and in particular to a flexible control device for circulating water systems suitable for fluctuating new energy sources. Background Technology

[0002] In the production and operation of new energy sources, the output power of power generation equipment exhibits significant fluctuations due to natural environmental factors such as wind and sunlight. These power fluctuations directly lead to rapid and substantial changes in the heat exchange requirements of the cooling system. However, existing circulating water systems mostly adopt fixed pipeline connections or single pump operation modes, lacking the ability to flexibly switch flow path structures to cope with power fluctuations. When the output power of new energy is low, the circulating water system maintains its original operating state, resulting in excessive system energy consumption and energy waste. When the output power increases instantaneously, the fixed pipeline structure makes it difficult to quickly increase the flow rate or pressure to meet peak heat dissipation requirements by changing the series and parallel connection methods. This results in poor adaptability of the circulating water system to fluctuating operating conditions, making it impossible to achieve efficient matching of water resource transportation and energy utilization.

[0003] Furthermore, during the long-term operation of the circulating water system, impurities in the water are easily attached to the surface of the filter components. Existing filter devices adopt a static interception structure and lack online self-cleaning function. As the usage time increases, the impurities accumulated on the filter screen will lead to increased water flow resistance and reduced flow rate. This will not only further weaken the control precision and heat exchange efficiency of the circulating water system, but also often require manual shutdown for cleaning and maintenance, which seriously affects the continuous and stable operation of new energy power generation equipment and makes it difficult to meet the dual requirements of modern new energy systems for flexible control and high reliability.

[0004] Therefore, this invention proposes a flexible control device for circulating water systems of fluctuating new energy sources to address the shortcomings of existing technologies. Utility Model Content

[0011] Preferably, in order to optimize the spatial layout and improve the compactness of the heat exchange structure, the heat exchanger is located on the side of the water pump away from the motor, and the fixed shell covers the connection between the water pump and the heat exchanger.

[0012] Preferably, in order to achieve flexible switching of water circuits, including single-circuit operation, multi-circuit parallel or series boosting modes, the switch is set at the water pump input end, one end of the series pipe is connected to the switch, and the other end of the series pipe extends to the input position of the adjacent water pump.

[0013] Preferably, in order to increase the filtration area and improve the filtration efficiency, filter screens are provided on the upper and lower sides of the inner wall of the storage tank, and the filter screens are distributed circumferentially along the inner wall of the storage tank.

[0014] Preferably, in order to ensure the smooth operation of the internal rotating components, the rotating plate is located at the bottom of the inner cavity of the storage tank, and the rotation center axis of the rotating plate coincides with the vertical center line of the storage tank.

[0037] Working Principle: In the production operation scenario, to optimize the stability of energy output, control cabinet 1 collects the power of the new energy source and the parameters of the circulating water system. It precisely adjusts the circulation mechanism 2 and the filtration mechanism 3 based on power fluctuations. The main pipeline 5 connected to the right end of control cabinet 1 and the main control valve 4 work together. The main control valve 4 throttles all pipeline connections. The circulation mechanism 2 at the bottom of the main pipeline 5 precisely adjusts the flow rate of the circulating water and achieves efficient heat exchange based on the fluctuations in the new energy output, ensuring stable new energy production. Multiple sets of water pumps 201 and motors 207 connected to the bottom of the main pipeline 5 operate collaboratively.

Control valve 204 enables precise regulation of the circulating water flow rate and pressure and connects different numbers of water pumps 201. Switch 203 and series pipe 202 connected to the front end of water pump 201 work together. Each switch 203 precisely controls the series pipe 202 at each interface, improving the flexibility of adjustment. The series pipe 202 flexibly switches the water flow path according to needs, enabling parallel delivery of single and multiple circulating water, and increasing the circulating water flow rate. When the power and load are low, the system energy consumption is reduced to achieve efficient utilization of water resources and energy. To improve the cleanliness of the circulating water after regulation, the filter mechanism 3 connected to the bottom rear side of the main pipe 5 treats the water.
