[0042] Specifically, the anemometer 16 monitors wind speed and direction in real time and transmits the data to the intelligent control device 13. The intelligent control device 13 calculates the optimal height of the fan column 3.1 based on the wind speed and direction data, and drives the automatic lifting device 2 through the control motor 12 to extend and retract the fan column 3.1 to the optimal position. The rectifier 18 converts AC power to DC power and distributes it to the heat storage heating system, the retractable annular heat pipe system and the battery 8 through cables.

[0053] Specifically, the heat storage tank 9 is equipped with a temperature measuring device, which on the one hand facilitates monitoring the hot water temperature at the inlet of the tube bundle heating tube 2, and on the other hand compares it with the oil temperature in the tank, so as to control whether hot water enters the tube bundle heating tube 2.

[0054] Specifically, a combination of tube bundle heating tube 2 and retractable annular heat pipe 15 is used for heating, with overall and local heating working together to ensure uniform temperature distribution of the oil in the tank.

[0055] In other preferred embodiments, the data acquisition and control system includes an intelligent control device 13, an infrared temperature sensor 14, an ultrasonic level sensor 17, and a pressure sensor 19. The motor 12, the infrared temperature sensor 14, the ultrasonic level sensor 17, and the pressure sensor 19 are all electrically connected to the intelligent control device 13. The infrared temperature sensor 14 is located at the top of the floating roof tank 1, the ultrasonic level sensor 17 is located at the bottom of the floating roof tank 1, and there are multiple pressure sensors 19, which are respectively located at the bottom of the secondary annular heat pipe 5, the tertiary annular heat pipe 6, and the quaternary annular heat pipe 7. The motor 12 is electrically connected to the rectifier 18.

[0056] Specifically, rectifier 18 converts the alternating current generated by the wind power generation system into direct current to power motor 12.

[0057] Specifically, pressure sensors 19 are arranged at the bottom of each annular heat pipe. When a malfunction occurs and the expansion and contraction cannot be completed, the pressure signal is fed back to the intelligent control device 13. Pressure sensors 19 can monitor the expansion and contraction status and pressure changes of the annular heat pipe and promptly feed back to the intelligent control device 13 to avoid safety accidents.

[0058] Specifically, the infrared temperature sensor 14 is a non-contact infrared temperature sensor TS105, with an operating temperature of -20℃ to 100℃ and a measurement accuracy of <2%FS; the ultrasonic liquid level sensor 17 is a KS103 ultrasonic ranging module.

[0059] Specifically, the infrared temperature sensor 14, the ultrasonic liquid level sensor 17, the motor 12, and the pressure sensor 19 are connected to the intelligent control device 13 via data transmission lines, and the intelligent control device 13 can remotely control the start and stop of the motor 12.

[0060] Specifically, the infrared temperature sensor 14, the ultrasonic level sensor 17, and the pressure sensor 19 monitor the crude oil temperature, liquid level, and status of the annular heat pipe in the tank, respectively, and transmit the data to the intelligent control device 13. The intelligent control device 13 performs control calculations based on the collected data and a preset program, and issues control commands based on the calculation results to control the motor 12 to drive the automatic lifting device 20, adjust the height of the retractable annular heat pipe 15, realize local heating of crude oil at different liquid levels, and ensure the uniformity of crude oil temperature.

[0061] Specifically, the data acquisition and control system can monitor the crude oil temperature, liquid level and annular heat pipe status in the floating roof tank 1 in real time, providing accurate data for the intelligent control device 13 and ensuring control precision.

[0063] Specifically, since the wall of the floating roof tank 1 exchanges heat with the atmospheric environment, the number of retractable annular heat pipes 15 near the wall of the floating roof tank 1 is slightly denser at the center of the tank.

[0064] Specifically, by rationally arranging the retractable annular heat pipes 15 according to the temperature difference between the tank wall and the tank center, heating efficiency can be improved and energy consumption can be reduced. By rationally arranging the retractable annular heat pipes, the uniformity of crude oil temperature inside the tank can be ensured, and local overheating or undercooling can be avoided.

[0066] Specifically, the bottom of the first-stage annular heat pipe 4 in the retractable annular heat pipe 15 is provided with four oil drain holes to prevent crude oil from remaining in the hollow part of the annular heat pipe when the oil level in the tank drops.

[0067] The operating principle of the heating method in this application is as follows:

[0068] When oil is stored in the floating roof tank 1, the temperature of the oil inside the tank is monitored by an infrared temperature sensor 14. If the temperature is lower than that of the hot water in the thermal storage tank 9, the thermal storage heating system is activated, and the oil is heated through the tube bundle heating pipe 2. The ultrasonic level sensor 17 monitors the oil level. If the oil located far from the tube bundle heating pipe 2 is heated slowly, the intelligent control device 13 controls the motor 12 to start, which in turn controls the retractable annular heat pipe 15 to extend and retract, thereby heating the oil inside the tank.
