[0035] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0036] Example 1:

[0037] refer to Figures 1-3A bottom cathode measuring tool for an electrolytic cell includes a support rod 11, a movable base 12, a crossbeam 21, and a probe 22. The movable base 12 is vertically slidably connected to the support rod 11, and the crossbeam 21 is horizontally slidably connected to the movable base 12. A level 28 is fixedly installed on the crossbeam 21. The level 28 is used to measure whether the crossbeam 21 is horizontal, ensuring that the crossbeam 21 is horizontal during the measurement process. The upper end of the probe 22 is connected to one end of the crossbeam 21, and the probe 22 is vertically positioned. A support block 13 is fixedly connected to the support rod 11, and an elastic element 14 (a spring) is provided between the support block 13 and the movable base 12. A scale 15 is fixedly installed on the support block 13, and the scale 15 is vertically positioned. A calibration plate 16 is fixedly connected to the movable base 12, and the calibration plate 16 is located at the scale 15. The surface of the scale 15 has distance markings.

[0038] The support rod 11 is threaded with a screw 23, which abuts against the probe rod 22. Tightening the screw 23, which presses against the probe rod 22, locks the probe rod 22 in place through friction, thus fixing it in place. The probe rod 22 has a positioning hole 24, and a positioning pin 25 is fixedly connected to the screw 23 and inserted into the positioning hole 24. Inserting the positioning pin 25 into the positioning hole 24 positions and further locks the probe rod 22. A limiting rod 26, which engages with the crossbeam 21, is fixedly connected to the upper end of the probe rod 22. The limiting rod 26 is perpendicular to the probe rod 22. After the probe rod 22 is inserted into the crossbeam 21 from top to bottom, it engages with the crossbeam 21 through the limiting rod 26, thus limiting the probe rod 22 and preventing it from passing through the crossbeam 21 and slipping off. A sleeve 27, which is fitted onto the probe rod 22, is fixedly connected to the crossbeam 21. The sleeve 27 supports the side wall of the probe rod 22, providing lateral support force to the probe rod 22.

[0039] This embodiment has the following advantages:

[0040] Insert the probe 22 into the bottom of the electrolytic cell, and then place the support rod 11 on an object to provide support for the support rod 11. Slide the crossbeam 21 horizontally on the movable seat 12 to adjust the horizontal position of the probe 22, moving it to the highest position at the bottom of the electrolytic cell. Then, press the movable seat 12 downwards on the support rod 11, causing the movable seat 12 to move the crossbeam 21 and the probe 22 downwards. Simultaneously, the movable seat 12 moves the calibration plate 16 downwards, bringing the probe 22 into contact with the bottom of the electrolytic cell. Record the corresponding scale value on the scale 15 of the calibration plate 16 at this point. This scale value corresponds to the depth of the bottom of the electrolytic cell at the current position of the probe 22, obtaining the scale value at the highest point of the electrolytic cell. Then, move the crossbeam 21 horizontally on the movable seat 12 and press the movable seat 12 downwards again, moving the probe 22 downwards until it contacts the bottom of the electrolytic cell. Record the corresponding scale value on the scale 15 of the calibration plate 16 at this point again. After repeatedly measuring different locations at the bottom of the electrolytic cell, the scale value of the lowest point is obtained, which represents the most severely damaged area at the bottom of the cell. Since damage to the bottom of the electrolytic cell is usually localized, after multiple measurements, the highest point is determined to be the location where there is no damage or only minor damage. The depth of the damage can be measured by the difference between the highest and lowest points, achieving good measurement accuracy and enabling precise determination of the damage extent at the bottom of the electrolytic cell.

[0041] During the measurement process, the operator moves the probe 22 to the electrolytic cell via the crossbeam 21. The operator only needs to operate from the movable seat 12, which is far away from the electrolytic cell, which can improve safety and prevent the operator from being injured by the corrosive liquid and high temperature of the electrolytic cell.

[0042] Example 2:

[0043] refer to Figures 4-5 A bottom cathode measuring tool for an electrolytic cell, differing from Embodiment 1 in that it further includes a support base. The support base comprises a rotating seat 31 and a support frame 41. The rotating seat 31 is rotatably mounted on the support frame 41. A support sleeve 32 is fixedly connected to the rotating seat 31. A support rod 11 is inserted into the support sleeve 32, and the support rod 11 is circumferentially engaged with the support sleeve 32. Rotating the rotating seat 31 on the support frame 41 causes the support rod 11, the crossbeam 21, and the probe 22 to rotate, facilitating the adjustment of the probe 22. A counterweight frame 33 is fixedly connected to the rotating seat 31. The counterweight frame 33 is located on the side of the rotating seat 31 away from the probe 22. A connecting post 34 is fixedly connected to the end of the counterweight frame 33 away from the probe 22. A counterweight block 35 is provided on the counterweight frame 33, and the connecting post 34 passes through the counterweight block 35. The counterweight 33 balances the torque on the support frame 41, making the support frame 41 equilibrated and preventing the measuring tool from tipping over to the probe 22 during use, thus improving stability.

[0044] The support frame 41 is fixedly connected to multiple legs 42, and each leg 42 is threadedly connected to a stud 43. The stud 43 is vertically positioned, and a foot 44 is fixedly connected to its lower end. When the ground is uneven, rotating the foot 44 causes the stud 43 to rotate. As the stud 43 rotates, it moves vertically on the foot, thereby adjusting the distance between the foot 44 and the legs 42 to adapt to uneven ground and ensure that the crossbeam 21 remains horizontal. A thrust bearing 45 is provided at the upper end of the support frame 41, and its upper end engages with the rotating seat 31. A ball bearing 46 is installed at the lower end of the support frame 41, and it is fitted onto the rotating frame. The thrust bearing 45 provides upward support for the rotating seat 31, while the ball bearing 46 provides lateral support to the rotating seat 31, preventing lateral deflection and ensuring stable rotation of the rotating seat 31 on the support frame 41.
