[0053] In one embodiment, the wind power generation assembly is arranged behind the airflow resistance body 12 along the flow direction of the incoming airflow, and is used for generating power by using the vortex generated by the incoming airflow when the Karman vortex street phenomenon occurs. The wind power generation assembly can be various assemblies. The battery unit is arranged in the electric control box 7, and the battery of the battery unit can be a lithium battery or the like. The battery unit is connected with the wind power generation assembly, and stores the electric energy generated by the wind power generation assembly through power generation.
[0054] The number of airflow resistance bodies 12 is multiple, the wind power generation assembly comprises a plurality of power generation modules, the airflow resistance bodies 12 and the power generation modules are arranged in correspondence, which can be one-to-one correspondence or one-to-many correspondence, and the like, and each power generation module is connected with the battery unit.

After the power generation amount is stable, the external power supply can be replaced to provide electric energy for the corresponding electric power equipment.
[0056] The application provides an energy-saving power system of a cooling tower. The wind power assembly is arranged in the cooling tower to provide power for the electric equipment. When the power generated by the wind power assembly can fully meet the power consumption of the electric equipment in the cooling tower, the external power supply is stopped to provide power for the electric equipment by the wind power assembly. When the power generated by the wind power assembly can only meet the power consumption of part of the electric equipment, the low-power-consumption electric equipment such as electromagnetic valves and sensors is preferentially powered, and the excess power is used to power the high-power-consumption electric equipment such as electric motors and circulating water pumps for a limited time.

[0059] Figure 5 The flowchart of one embodiment of the control method of the cooling tower device based on the present application is shown in FIG. 5. The control method is executed in the control unit, as shown in FIG. 5. Figure 5
[0060] Step 501: The fan system and the heat exchange circulating system are controlled to start and run, and the external power supply is controlled to provide power for the electric equipment. The electric equipment includes sensors, electromagnetic valves, circulating water pumps, electric motors in the fan system and the like.
[0061] Step 502: According to the charging power of the battery unit and the power consumption of the electric equipment, the battery unit and / or the external power supply is controlled to provide power for the electric equipment.
[0062] In one embodiment, the control of the battery unit, the external power supply to provide power to the power device can be achieved in a variety of ways. In the case of the charging power of the battery unit is greater than the total power consumption of all power devices, control the battery unit to provide power to all power devices. In the case of the charging power of the battery unit is less than the total power consumption of all power devices, control the battery unit to provide power to part of the power device. The control unit can be achieved in a variety of ways to obtain the charging power of the battery unit and the amount of power, the total power consumption of all power devices is a constant value, the designer can determine the total power consumption of all power devices in the design stage. The charging power of the battery unit is greater than the total power consumption of all power devices, that is, to determine the power generation of the wind power assembly to fully meet the power consumption of all power devices, control the battery unit to provide power to the power device.
[0063] In one embodiment, in the case of the charging power of the battery unit is greater than the charging power threshold, control the battery unit to provide power to low-power devices. High-power devices include circulating water pumps and motors in the fan system, and low-power devices include sensors and solenoid valves in the heat exchange circulation system.
[0064] The charging power threshold can be set, the charging power threshold can be greater than the total power consumption of low-power devices, less than the total power consumption of all power devices. In the case of the charging power of the battery unit is greater than the charging power threshold, it can be determined that the power generation of the wind power assembly is stable. After the fan system and the heat exchange circulation system are started and run, the motor drives the fan blade of the exhaust fan to produce an outward suction force. When the exhaust fan is stable, it can be considered that the air entering the cooling tower through the airflow resistance body is constant speed, and the rotor is also in a stable state of cutting the magnetic induction line, which can generate a stable current for charging. At this time, the charging power of the battery is greater than the charging power threshold, and the power generation of the wind power assembly is stable.
[0065] The power consumption of sensors and solenoid valves is low, and the battery unit will preferentially supply power to low-power devices such as solenoid valves and sensors. When the exhaust fan is stable, the charging power of the battery unit is greater than the charging power threshold, and the charging power threshold is greater than the power consumption of the sensor and the solenoid valve, that is, the use power, the battery unit can supply power to low-power devices such as sensors and solenoid valves. The battery unit can not supply power to all solenoid valves and sensors at one time, and the supply sequence can be determined in the order of low to high power consumption of low-power devices such as solenoid valves and sensors. The battery unit supplies power to low-power devices such as solenoid valves and sensors in sequence based on the supply sequence, and a variety of power supply methods can be used. If the power generation of the wind power assembly exceeds the power consumption of low-power devices, the excess power generation of the wind power assembly will be charged into the battery unit as a surplus power.
[0066] In one embodiment, when the amount of electricity stored in the battery unit is greater than a first electricity threshold, the battery unit is controlled to provide electricity for at least one high-power consumption electrical device; and when the amount of electricity stored in the battery unit is less than a second electricity threshold, the external power source is controlled to provide electricity for all high-power consumption electrical devices.
[0067] The first electricity threshold is greater than the second electricity threshold, and the first electricity threshold can be 80% of the total electricity of the battery unit, and the second electricity threshold can be 20% of the total electricity of the battery unit. When the amount of electricity stored in the battery unit is greater than the first electricity threshold, the battery unit is controlled to be in a power supply state, and the battery unit is controlled to provide electricity for at least one high-power consumption electrical device, and when the amount of electricity stored in the battery unit is less than the second electricity threshold, the battery unit is controlled to be in a charging state.
[0068] Figure 6 A control flow diagram for supplying power to high-power consumption electrical devices in one embodiment of the control method of the present disclosure is shown in FIG. 6 as follows: Figure 6
[0069] In step 601, at least one high-power consumption electrical device is selected as a target high-power consumption electrical device based on the amount of electricity of the battery unit and according to the order of power consumption from small to large. At least one high-power consumption electrical device can also be selected based on the amount of electricity of the battery unit and according to the order of power consumption from large to small.
[0070] In step 602, the battery unit is controlled to provide electricity for the target high-power consumption electrical device.
[0071] In one embodiment, the high-power consumption electrical devices include a first motor, a second motor, and a circulating water pump, and the order of power consumption from small to large is the circulating water pump < the first motor < the second motor. The current amount of electricity of the battery unit is obtained, and when the current amount of electricity of the battery unit is greater than 50% of the total amount of electricity of the battery unit, all high-power consumption electrical devices are selected as target high-power consumption electrical devices according to a pre-set target device selection strategy, i.e., the target high-power consumption electrical devices are the circulating water pump, the first motor, and the second motor, or the circulating water pump and the first motor with the smallest power consumption are selected as target high-power consumption electrical devices, and the battery unit is controlled to provide electricity for the target high-power consumption electrical devices. Various methods can be used to control the battery unit to supply power, for example, the battery unit and the external power source can be controlled to alternately provide electricity for the target high-power consumption electrical devices. When the current amount of electricity of the battery unit is less than or equal to 50% of the total amount of electricity of the battery unit, the circulating water pump with the smallest power consumption is selected as the target high-power consumption electrical device, i.e., the device with small power consumption is preferentially supplied with power.
