[0024] When in use, the motor controller 6 controls the driving motor 7 to work, and the driving motor 7 drives the second winding disk 302 and the first winding disk 301 to rotate, so that the first connecting line 303 on the outside of the first winding disk 301 is wound around the second winding disk 302 and goes out, and the second connecting line 304 on the outside of the second winding disk 302 moves down, so that the detection probe 5 can be put into the liquid, and the first winding disk 301 and the second winding disk 302 are reversed, so that the first connecting line 303 on the outside of the second winding disk 302 is wound around the outside of the first winding disk 301, so that the second connecting line 304 after moving down can be wound around the outside of the second winding disk 302, and the detection probe 5 can be pulled upward.

[0025] For example, Figure 3 As shown, the utility model also includes that an externally threaded butt pipe 403 is welded on the top of the protection tube 401, a sealing sleeve 404 is glued inside the externally threaded butt pipe 403, and the protection tube 401 is connected to the bottom of the rectangular box body 1 through the externally threaded butt pipe 403.

[0026] When in use, the protection tube 401 is connected to the bottom of the rectangular box body 1 through the external threaded butt tube 403 for easy disassembly, and the sealing sleeve 404 is sealed between the external threaded butt tube 403 and the second connecting line 304 .

[0027] For example, Figure 2 As shown, the utility model also includes that the top end of the first connecting line 303 is connected to the immersion liquid level transmitter body 2 , and the bottom end of the first connecting line 303 is connected to the top end of the second connecting line 304 .

[0028] When in use, the first connecting line 303 and the second connecting line 304 transmit the data detected by the detection probe 5 to the submersible liquid level transmitter body 2 .

[0029] For example, Figure 2 As shown, the utility model also includes that a first belt pulley 306 is sleeved on the outer side of the rotating shaft of the first winding disk 301, a second belt pulley 307 is sleeved on the outer side of the rotating shaft of the second winding disk 302, and belts 308 are sleeved on the outer sides of the first belt pulley 306 and the second belt pulley 307.

[0031] For example, Figure 2 As shown, the utility model also includes that auxiliary wheels 305 are fixed to the top and bottom of the rectangular box body 1 by bolts.

[0032] When in use, the auxiliary wheels 305 are arranged so that the first connecting line 303 and the second connecting line 304 will not scratch the inner side of the rectangular box body 1 when moving.

[0033] For example, Figure 1 As shown, the utility model also includes that the bottom of the rectangular box body 1 located outside the protection tube 401 is fixed with a flange 8 by bolts, and the current output end of the motor controller 6 is electrically connected to the current input end of the drive motor 7 through a power line.

[0035] When the utility model is used, a person uses bolts to install the device on a container containing liquid through a flange 8, and uses a power cord to connect the device to an external power source;

[0036] The driving motor 7 is controlled by the motor controller 6 to work, and the driving motor 7 drives the second winding disk 302 to rotate, and drives the first winding disk 301 to rotate through the second belt disk 307, the belt 308 and the first belt disk 306. The second winding disk 302 rotates to release and reel in the line, so that the second connecting line 304 on the outside of the second winding disk 302 moves downward, and the first winding disk 301 rotates to release the line, so that the first connecting line 303 on the outside of the second winding disk 302 moves downward and is wound around the outside of the second winding disk 302. When the second connecting line 304 moves downward, the detection probe 5 from the bottom is put into the liquid in the container. After the detection is completed, the first winding disk 301 and the second winding disk 302 are driven to reverse by the driving motor 7, and the first connecting line 303 wound on the outside of the second winding disk 302 is wound around the outside of the first winding disk 301, and the second connecting line 304 after moving downward is wound around the second winding disk 302, and the detection probe 5 is pulled upward;

[0037] After the detection probe 5 moves up, it enters the protection tube 401. The rubber ring 402 is tightly attached to the outside of the detection probe 5, which can clamp the detection probe 5 entering the protection tube 401 to prevent it from loosening. The sealing sleeve 404 seals between the external threaded butt tube 403 and the second connecting line 304 to prevent liquid from entering the rectangular box body 1. The setting of the auxiliary wheel 305 prevents the first connecting line 303 and the second connecting line 304 from scratching the inner side of the rectangular box body 1 when moving.
