Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.
[0018] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. Example 1 like Figures 1-7 As shown, an adjustable liquid level measuring device includes components such as a handle 1, a fixed base 2, a turntable 3, and a probe 5.
[0019] like Figures 1-19 As shown, one end of the handle 1 is connected to the fixed base 2. The fixed base 2 is hollow inside, and a turntable 3 is rotatably mounted inside the fixed base 2. Specifically, a connector 21 extends from one end of the fixed base 2 and is connected to the handle 1. A shaft hole 27 is provided through the fixed base 2, and a rotating shaft 34 is detachably mounted at the center of the turntable 3. The rotating shaft 34 is rotatably mounted in the shaft hole 27.
[0020] like Figures 1-19As shown, one side of the rotating disc 3 is provided with a sleeve 31, and one end of the drill rod 5 is arranged in the sleeve 31. Specifically, the sleeve 31 is provided with a plurality of threaded holes 312 around the circumference, and connecting screws 311 are screwed in the threaded holes 312. When the drill rod 5 is inserted into the sleeve 31, the connecting screws 311 can be tightened, which facilitates the disassembly and assembly of the drill rod 5 and the sleeve 31, thereby facilitating the replacement of the damaged drill rod 5.
[0021] As shown in Figure 14 , 15 , the side wall of the rotating disc 3 is provided with a through hole one 32 and a through hole two 33, the through hole one 32 is located on a concentric circle with a diameter of R2, the through hole two 33 is located on a concentric circle with a diameter of R1, R1 is greater than R2, and the through hole one 32 and the through hole two 33 have a fixed angle b° between them.
[0022] As shown in Figures 17-19 , the side wall of the fixed seat 2 is provided with a through hole three 22 and a through hole four 23, the through hole three 22 is located on a concentric circle with a diameter of R2, the through hole four 23 is located on a concentric circle with a diameter of R1, R1 is greater than R2, and the through hole three 22 and the through hole four 23 have a fixed angle c° between them, and b is less than c.
[0023] As shown in Figures 1-19 , since the angle between the through hole one 32 and the through hole two 33 is b°, and the angle between the through hole three 22 and the through hole four 23 is c°, the two angles are different, when the through hole one 32 and the through hole three 22 are opposite, the through hole two 33 and the through hole four 23 are staggered, then the plug assembly is inserted into the through hole one 32 and the through hole three 22 to realize the fixation of the rotating disc 3 and the fixed seat 2. Conversely, when the through hole two 33 and the through hole four 23 are opposite, the through hole one 32 and the through hole three 22 are staggered, and the plug assembly is inserted into the through hole two 33 and the through hole four 23 to realize the fixation of the rotating disc 3 and the fixed seat 2.
[0024] Such design can set the through hole structure on a rotating disc 3 and a fixed seat 2 with limited volume, by setting each through hole on concentric circles with different diameters, staggered with each other, and allowing the plug assembly to be clamped in different position through holes, the fixation of the rotating disc 3 and the fixed seat 2 is realized, and such structure can realize small angle adjustment, especially small angle adjustment within 5-10°, which can facilitate small angle adjustment, thereby reducing the volume of the measuring device, and adjusting the small angle according to the actual situation of the electrolytic cell to measure the liquid level of the electrolyte and aluminum liquid in the electrolytic cell. Figure 2 At this time, the angle between the handle 1 and the drill rod 5 after adjustment is a°, and a is 150°; when the angle between the handle 1 and the drill rod 5 needs to be adjusted to 145°, the angle change is only 5°, then the angle between the through hole one 32 and the through hole two 33 is set to b°, at this time b is 5, the angle between the through hole three 22 and the through hole four 23 is c°, and c can be selected as 10.
[0025] The purpose of such design is mainly because: when the adjustment angle is small, and the outer diameter of the fixed seat 2 and the rotating disc 3 is small, it is impossible to set multiple through hole structures on the same concentric circle with the same diameter (i.e. it is impossible to set multiple through holes 32 on the concentric circle with the diameter R2, because when the angle between two adjacent through holes 32 is small, the two through holes 32 will necessarily intersect each other), and the multiple through hole structures will interfere with each other and cannot be fixed by the bolt.
[0026] Embodiment 2 This embodiment further optimizes the design of the bolt assembly.

[0029] When the spring 62 and the spring 6 are not compressed, the ends of the bolt 63 and the bolt 61 extend to the outside of the rotating disc 3. When the through hole 32 and the through hole 23 are opposite, the through hole 33 and the through hole 24 are staggered, the end of the bolt 63 extends into the through hole 23 to be fixed, the spring 62 is not compressed, and the end of the bolt 61 extends into the sliding groove 26 to be fixed, the spring 6 is compressed. When the through hole 33 and the through hole 24 are opposite, the through hole 32 and the through hole 23 are staggered, the end of the bolt 61 extends into the through hole 23 to be fixed, the spring 6 is not compressed, and the end of the bolt 63 extends into the sliding groove 25 to be fixed, the spring 62 is compressed (as shown in 6).
