[0040] In one embodiment, there are two shaft sleeves 301 and two guide rods 305. The two shaft sleeves 301 are respectively sleeved on both ends of the screw rod 302. The setting of the shaft sleeves 301 can fix the screw rod 302 and ensure the stability and reliability of the screw rod 302.

[0043] Working principle: When in use, first, through the precise control of the lifting mechanism 2, the cover plate 7 can quickly and smoothly open or close the detection port. Subsequently, the adjusting mechanism 3, driven by the servo motor 303, drives the moving rod 304 to move left and right under the precise guidance of the shaft sleeve 301 and the guide rod 305 through the rotation of the screw rod 302, thereby adjusting the horizontal position of the ultrasonic detector 1. At the same time, the lifting mechanism 2 uses the power of the cylinder 202 to drive the mounting plate 205 and the ultrasonic detector 1 thereon to move up and down. In this process, the guide sleeve 203 and the connecting rod 204 ensure the smoothness and precision of the moving process. Through the coordinated work of the lifting mechanism 2 and the adjusting mechanism 3, the device can flexibly adapt to different working environments and requirements, ensuring that the ultrasonic detector 1 can be accurately positioned at the optimal detection position. Finally, the ultrasonic detector 1 accurately analyzes the reflected signal of the molten aluminum level by sending and receiving ultrasonic signals, thereby accurately determining the height of the molten aluminum level.

[0044] In summary, this molten aluminum level detection device, through the combination of the lifting mechanism 2 and the adjustment mechanism 3, enables the ultrasonic detector 1 to be flexibly adjusted in the horizontal and vertical directions, so that the ultrasonic detector 1 can be more accurately positioned to the liquid surface of the molten aluminum. This precise positioning helps to reduce errors and improve the accuracy of liquid level detection, thereby adapting to different working environments and needs. Through the coordinated drive of the servo motor 303 and the cylinder 202, the detection device realizes automatic control, which not only speeds up the speed of finding the best detection position, but also shortens the overall detection time and significantly improves work efficiency. At the same time, this automated design also reduces the difficulty of manual operation and reduces human errors, bringing revolutionary progress to molten aluminum level detection. Through the design of the cover plate 7, the detection port can be effectively closed to prevent molten aluminum from splashing, thereby improving the safety of the production process.
