[0024] The technical solution of the present invention is further described below with specific embodiments, but the protection scope of the present invention is not limited to the following embodiments.

[0025] Implementation method 1: Figures 1 to 3 As shown, the temperature measuring device dedicated to the electrolytic cell with energy storage function includes a main housing 1, a telescopic wire tube 2 connected to the bottom of the main housing 1, and a touch screen 3 installed on the front of the main housing 1. A main control board 4 is provided in the main housing 1, and a thermocouple electrode probe 5 electrically connected to the main control board 4 is installed at the bottom end of the telescopic wire tube 2, wherein the main control board 4 is integrated with an acquisition circuit module 41, a conditioning and amplification module 42, a single-chip microcomputer 43, a wireless data transmission module 44 and a power conversion module 45. The thermocouple electrode probe 5 is connected to the input end of the single-chip microcomputer 43 through the acquisition circuit module 41 and the conditioning and amplification module 42 in sequence. The single-chip microcomputer 43 is serially connected to the wireless data transmission module 44 and the touch screen 3. The power conversion module 45 supplies power to the acquisition circuit module 41, the single-chip microcomputer 43, the wireless data transmission module 44 and the touch screen 3, and the conditioning and amplification module 42 draws power from the single-chip microcomputer 43.

[0026] Implementation 2: This temperature measurement device for an electrolytic cell with an energy storage function. The telescopic wire tube 2 includes a joint 21, a base wire tube 22 fixed to the joint 21, and a movable sleeve 23 sleeved outside the base wire tube 22. The thermocouple electrode probe 5 is fixed to the lower end of the movable sleeve 23. The telescopic wire tube is extended and shortened by stretching the movable sleeve to determine the temperature measurement depth. A winding post 221 is provided in the center of the base wire tube 22, and the wire between the main control board 4 and the thermocouple electrode probe 5 is wound on the winding post 221. This prevents the wire from being damaged by straight bending during the extension and retraction of the movable sleeve. The base wire tube 22 and the movable sleeve 23 are both made of 316 molybdenum-containing alloy profile. The lower end of the movable sleeve 23 is filled with FKM fluororubber filler 24 on the outer periphery of the thermocouple electrode probe 5. An HNBR hydrogenated nitrile rubber corrugated sealing tube 25 is provided between the base wire tube 22 and the movable sleeve 23. This bellows seal is used to ensure corrosion resistance of the overall material of the telescopic conduit and to provide a watertight seal in the conduit cavity, preventing electrolyte from entering the conduit and corroding the electrical conductors and the circuit board within the main housing above. The bellows seal also provides damping for positioning the movable sleeve after extension. The remaining structure and components are as described in Embodiment 1 and will not be repeated here.

[0027] Implementation 3: This temperature measurement device for electrolytic cells with energy storage function utilizes an STM32F105R microprocessor with an integrated analog-to-digital conversion module. In addition to providing processor-based control functions for other functional modules, it can also directly perform analog-to-digital conversion on input signals. The touch screen 3 and wireless data transmission module 44 are connected to the microcontroller 43 via the TXD1 / RXD1 / GND1 and TXD2 / RXD2 / GND2 pin groups, respectively. This enables serial bidirectional communication between the touch screen, wireless data transmission module, and the microcontroller. The acquisition circuit module 41 utilizes the MAX31850 acquisition module 6675, and the conditioning and amplification module 42 utilizes the ADA4470 signal processing module. The MAX31850 acquisition module is capable of acquiring and converting potential differences with various thermocouple types, including K, J, N, T, and E. The ADA4470 signal processing module, in addition to providing stable conditioning, also performs signal amplification and filtering in the pre- and post-conditioning circuit stages. The remaining structures and components are as described in Implementation 1 and will not be described again.

[0028] During operation: the acquisition circuit module provides detection voltage to the thermocouple electrode probe, and collects the changes in electromotive force at two points of the thermocouple electrode probe, and outputs a weak current signal. The signal is processed by the conditioning and amplification module and the filtering module and then sent to the microcontroller for AD conversion. One path of the output digital signal is displayed through the touch screen, and the other path is sent to the host computer through the wireless data transmission module for remote monitoring. The touch screen can set parameters such as acquisition timing and acquisition frequency for the microcontroller.

[0029] The utility model discloses a temperature measuring device specially used for an electrolytic cell with an energy storage function, which overcomes the defects of existing industrial temperature measuring devices used for electrolytic cells, such as unstable signals in high and low temperature zones and susceptibility to corrosion of the instrument when used in the chemical and energy fields. The device performs a series of processing such as amplification, conditioning, and filtering on the collected signals, so that the signals remain stable in various temperature zones and has a remote monitoring function. At the same time, the probe part is designed to isolate the intrusion of acid and alkali solutions. The probe rod of the telescopic structure is adjustable in length, which is convenient for adjusting the sampled area or liquid level depth.
