[0002] The heat storage heater is the core equipment in the molten salt energy storage system. Its key role is to heat the molten salt to efficiently store thermal energy. In the energy storage stage, the equipment uses electric heaters or other heat sources to circulate and heat the molten salt in the storage tank to a high temperature state. Through advanced heating technology and materials, the heat storage heater can quickly and energy-savingly heat the molten salt to a predetermined temperature while minimizing energy loss. Its excellent stability and reliability ensure long-term, trouble-free operation. Therefore, the heat storage heater has been widely used in molten salt energy storage systems, solar thermal power generation systems and other fields, becoming a key link in converting low-grade energy into high-grade thermal energy, providing a solid guarantee for the stable operation and high-efficiency output of the entire system.

[0003] The inventor of this application found that there are the following problems in the practical use process:

[0004] At present, heat storage heaters are connected to multiple connecting pipes during use. However, during long-term use, due to thermal expansion and contraction of pipeline materials, aging and wear of flange rings, loosening or corrosion of fastening bolts, and possible minor manufacturing defects or improper installation, extremely small leaks may appear at the flange rings between pipelines. These leaks are often too subtle to be directly detected by the naked eye, but they may gradually accumulate, resulting in a decrease in the thermal efficiency of the system and may even cause greater safety hazards.

[0005] Therefore, it is necessary to provide a molten salt tank energy storage device to solve the above technical problems. Summary of the invention

The shell of the ultrasonic imager 4 is made of engineering plastic, which not only ensures the lightness of the equipment but also provides a good protection effect to prevent the external environment from damaging the internal of the equipment. This material selection takes into account both practicality and economy.

[0041] See also Figure 4 The energy storage heating device 1 includes a frame 101, and a heating tank body 102 is installed on the inner side of the frame 101. The energy storage heating device 1 is composed of the frame 101 and the heating tank body 102. This structural design is simple and clear, and is easy to install and maintain.

[0044] Embodiment 2:

[0045] See also Figure 1 , Figure 4 A motor is provided on one side of the slide rail 202, and the motor is used to drive the screw rod 204 to rotate. After the screw rod 204 rotates, it can cause the screw rod seat 205 to slide, and after the screw rod seat 205 slides, it can cause the ultrasonic imager 4 to translate periodically. The motor provided on one side of the slide rail 202 and the screw rod 204 rotation mechanism driven by it realize the automatic translation of the ultrasonic imager 4. This design not only reduces the burden of manual operation, but also improves the efficiency and accuracy of monitoring. Through the precise control of the motor, it can ensure that the ultrasonic imager monitors at the predetermined time and position, so as to timely discover and deal with potential leakage problems.

[0046] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 After the ultrasonic imager 4 is periodically translated, the first pipeline 103 and the second pipeline 104 can be leaked. By periodically translating the ultrasonic imager 4 and scanning and detecting it, the leakage of the first pipeline 103 and the second pipeline 104 can be comprehensively and systematically checked. This regular monitoring mechanism helps to timely discover and locate leakage points or potential fault points, so as to carry out repairs and maintenance in time to ensure the safe and stable operation of the energy storage heating device. At the same time, this monitoring method is also efficient, accurate, and comprehensive, which provides a strong guarantee for the long-term stable operation of the energy storage device.

[0047] During implementation, first, the energy storage heating device 1 is started to make the molten salt in the heating tank 102 reach a predetermined working temperature, and the motor on one side of the slide rail 202 is started through the control system, and the motor starts to drive the screw rod 204 to rotate, and the rotation of the screw rod 204 drives the screw rod seat 205 to move smoothly along the slide rail groove 203;

[0048] As the screw seat 205 moves, the first adjustment rod 206, the second adjustment rod 207 and the ultrasonic imager 4 are flexibly rotated through the damping shaft and adjusted to a proper detection angle and position, ensuring that the monitoring surface of the ultrasonic imager 4 is accurately aligned with the flange rings of the first pipeline 103 and the second pipeline 104;

[0049] The ultrasonic imager 4 starts to work, emitting ultrasonic waves and receiving reflected signals to form images. The operator observes the display screen of the ultrasonic imager and analyzes the images to detect whether there is slight leakage at the flange rings of the first pipeline 103 and the second pipeline 104;

[0050] The principle of the ultrasonic imager 4 for monitoring leakage points is that the piezoelectric crystal of the internal ultrasonic transmitter converts electrical energy into mechanical energy, generates ultrasonic waves and transmits them to the inside of the detected object, such as the pipe flange ring in the molten salt storage tank energy storage device. When the ultrasonic wave propagates inside the object, it will be reflected back when it encounters an interface with different acoustic impedance. These reflected signals are received by the receiver inside the imager and converted into electrical signals. After amplification, filtering and other processing, these electrical signals are transmitted to a computer or image processing system, and an image is generated using an algorithm. Areas of different brightness or color in the image represent different tissues or structures inside the detected object, thereby realizing visual detection and analysis of the internal structure of the object.

[0051] The advantages of this technical solution in practical applications include but are not limited to the following:

[0052] 1. The ultrasonic imager 4 can realize efficient and accurate monitoring of the first pipeline 103 and the second pipeline 104, timely discover and locate small leakage points, and avoid the decrease of thermal efficiency and safety hazards caused by leakage;

[0053] 2. The screw rod 204, the screw rod seat 205 and the first adjustment rod 206 and the second adjustment rod 207 connected to the damping shaft in the maintenance mechanism 2 enable the position and angle of the ultrasonic imager 4 to be flexibly adjusted to meet different pipelines and monitoring requirements, thereby improving the flexibility and accuracy of monitoring;

[0054] 3. The motor drives the screw rod 204 to rotate, thereby realizing the periodic translation of the ultrasonic imager 4, reducing the frequency and difficulty of manual operation, and improving the automation degree and work efficiency of monitoring.
