[0007] Preferably, the winding unit includes a winding frame, with a connecting positioning post rotatably connected to the inner side of the winding frame. A locking knob is installed at one end of the connecting positioning post, and a crank is installed on one side of the connecting positioning post. The end of the connecting positioning post away from the locking knob passes through the middle of the winding frame and is threadedly connected to the hand handle. The crank is rotatably connected to the winding frame. One end of the winding frame is provided with multiple positioning holes. One end of the locking knob passes through the connecting positioning post and is inserted into the inner side of one of the positioning holes. The locking knob is threadedly connected to the winding frame.

[0008] Preferably, the connecting cable includes an insulating filler layer, inside which a plurality of connecting steel wires are installed, and a battery cell body is installed between the plurality of connecting steel wires. The plurality of connecting steel wires are arranged in a circular pattern relative to the battery cell body.

[0011] Compared with the prior art, the present invention has the following advantages:
[0012] 1. Connect the handheld telescopic boom to a multi-segment telescopic boom composed of multiple threaded sleeves, so that the upper end of the connecting cable passes through the cable guide frame located at the front end of the multi-segment telescopic boom and is wound and connected to the reel. By adjusting the extension and retraction of the multi-segment telescopic boom, the length of the handheld telescopic unit can be adaptively adjusted by rotating the threads of the multiple sleeves to meet different usage environments. By shaking the reel with the handle, the counterweight measuring unit can be driven into the water body to be tested through multiple counterweight plates under the connection of the connecting cable.

[0013] 2. Helium gas is filled inside the mounting sleeve, between the elastic diaphragm and the mounting ring. Since helium gas is less affected by temperature, the elastic diaphragm can pressurize the helium gas under water pressure. The pressure sensor can then accurately measure the water level by monitoring the helium gas pressure inside the mounting sleeve. Furthermore, the pressure sensor does not directly contact the water body, effectively improving its service life. The counterweight allows the elastic diaphragm to automatically droop inside the guide sleeve when the counterweight measuring unit separates from the water body, maintaining a stable helium gas pressure inside the mounting sleeve. The retractable design also facilitates storage and carrying. Attached Figure Description

A crank handle 7 is installed on one side of the connecting positioning post 5. The end of the connecting positioning post 5 away from the locking knob 6 passes through the middle of the winding frame 4 and is threadedly connected to the handheld sleeve 1. The crank handle 7 is rotatably connected to the winding frame 4. Next, one end of the winding frame 4 is provided with multiple positioning holes. One end of the locking knob 6 passes through the connecting positioning post 5 and is inserted into the inside of one of the positioning holes. The locking knob 6 is connected to the winding frame 4 by threads. The upper end of the connecting cable 3 passes through the cable guide frame 8 and is fixedly wound around the outer side of the middle part of the winding frame 4. The locking knob 6 facilitates the locking and installation of the winding frame 4 and the connecting positioning post 5, keeping the winding frame 4 stable in suspending the counterweight measuring unit through the connecting cable 3, and winding the connecting cable 3 through the winding frame 4 for easy carrying and use.
[0024] As a preferred technical solution of this embodiment, as shown in Figures 2 and 3, a handheld telescopic unit is installed on one side of the winding unit. The handheld telescopic unit includes a handheld sleeve 1, and multiple telescopic sleeves 2 are installed on the inner side of the front end of the handheld sleeve 1. The multiple telescopic sleeves 2 are composed of multiple threaded sleeves that are sequentially fitted together. The diameter of the multiple threaded sleeves decreases sequentially. The handheld sleeve 1 is connected to one of the threaded sleeves by threads, and the cable guide frame 8 is fixedly connected to the front end of another threaded sleeve. The handheld sleeve 1 and the multiple threaded sleeves are coaxial. By adjusting the extension and retraction of the multiple telescopic sleeves 2, the length of the handheld telescopic unit can be adaptively adjusted by rotating the multiple threaded sleeves through the threads, which is convenient to meet different usage environments. Furthermore, the handheld sleeve 1 and the multiple telescopic sleeves 2 can be retracted for easy storage and use.
[0025] As a preferred technical solution of this embodiment, as shown in Figures 4 and 6, the counterweight measuring unit includes a mounting sleeve 9. The upper end of the mounting sleeve 9 is fixedly connected to the connecting cable 3. A mounting ring 16 is installed on the inner side of the upper end of the mounting sleeve 9. A pressure sensor 11 is installed on the inner side of the mounting ring 16. The pressure sensor 11 is electrically connected to the battery cell body 303. Multiple counterweight pieces 10 are fitted on the outer side of the bottom end of the mounting sleeve 9. The multiple counterweight pieces 10 facilitate the counterweight measuring unit to be counterweighted, thereby facilitating the stable suspension of the counterweight measuring unit in the water.
[0026] A guide sleeve 12 is installed on the inner side of the bottom end of the mounting sleeve 9. A pressure ring 13 is installed on the guide sleeve 12. The mounting sleeve 9 and the mounting ring 16 are connected by threads. The mounting sleeve 9 is fixedly connected to the pressure sensor 11. The mounting sleeve 9 and the guide sleeve 12 are fixedly connected by the pressure ring 13. A sealing ring is provided between the pressure ring 13 and the mounting ring 16 and the mounting sleeve 9. An elastic diaphragm 14 is provided between the upper end of the guide sleeve 12 and the pressure ring 13. A counterweight 15 is fixedly installed on the inner side of the middle of the elastic diaphragm 14. The side of the elastic diaphragm 14 is inserted between the guide sleeve 12 and the pressure ring 13. The middle of the elastic diaphragm 14 is bonded and fixed to the counterweight 15. Helium is filled between the elastic diaphragm 14 and the mounting ring 16. Since helium is less affected by temperature, the elastic diaphragm 14 can pressurize the helium under the action of water pressure. Thus, the pressure sensor 11 can accurately measure the water level by monitoring the gas pressure of the helium inside the mounting sleeve 9.
[0027] Working principle: When measuring water level, the handheld sleeve 1 is connected to the multi-segment telescopic sleeve 2 composed of multiple threaded sleeves. The upper end of the connecting cable 3 passes through the cable guide frame 8 located at the front end of the multi-segment telescopic sleeve 2 and is wound and connected to the winding frame 4. When the power is turned on, the multi-segment telescopic sleeve 2 is extended and retracted. The length of the handheld telescopic unit can be adjusted by rotating the threads of the multiple threaded sleeves to adapt to different usage environments. Then, the winding frame 4 is shaken by the crank handle 7. The winding frame 4 is connected to the counterweight measuring unit through the connecting cable 3. Under the connection of the connecting cable 3, the counterweight measuring unit can be driven to sink into the water body to be measured by multiple counterweight plates 10. When the counterweight measuring unit falls to the required depth, the winding frame 4 is locked.
[0028] Specifically, a plurality of positioning holes are provided at one end of the winding frame 4, and one end of the locking knob 6 passes through the positioning post 5 and is inserted into the inside of the positioning hole. The locking knob 6 is connected to the winding frame 4 by a thread, and the winding frame 4 and the connecting positioning post 5 can be locked and installed by the locking knob 6 to keep the winding frame 4 suspended stably on the counterweight measuring unit through the connecting cable 3.
[0029] Helium gas is filled inside the mounting sleeve 9, between the elastic diaphragm 14 and the mounting ring 16. Since helium gas is less affected by temperature, the elastic diaphragm 14 can pressurize the helium gas under the action of water pressure. Thus, the pressure sensor 11 can accurately measure the water level by monitoring the gas pressure of the helium gas inside the mounting sleeve 9. Moreover, the pressure sensor 11 does not directly contact the water body, which effectively improves the service life of the pressure sensor 11. The elastic diaphragm 14 is bonded and fixed to the counterweight 15. When the counterweight measuring unit is separated from the water body, the counterweight 15 can drive the elastic diaphragm 14 to automatically droop inside the guide sleeve 12, keeping the gas pressure of the helium gas inside the mounting sleeve 9 stable.
[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
