[0002] Steel tape level gauges are commonly used to measure water levels in wells, boreholes, and water level pipes, and are particularly suitable for groundwater level observation in hydropower projects or for manual inspection of the seepage line of earth-rock dams. Steel tape level gauges can be used during construction as well as for long-term safety monitoring of projects. In actual use, due to the weight of the measuring probe and the thinness of the steel tape, deformation can easily occur. During the raising and lowering of the measuring probe, the connection between the steel tape and the measuring probe is prone to deformation, making it impossible for the measuring probe to remain vertical. The contact area between the steel tape and the measuring probe is most easily jammed by the flange at the pump pipe joint in the well. Utility Model Content

[0023] like Figure 1-7 As shown, an anti-jamming water level gauge probe includes a probe body 4, with a protective cover 7 connected to the end of the probe body 4. A telescopic protective component 6 is connected to the upper end of the protective cover 7. The telescopic protective component 6 is sleeved on the outside of the steel tape cable 3. The telescopic protective component 6 protects the connection between the steel tape cable 3 and the probe body 4, preventing it from being jammed by the flange at the pump pipe joint in the well.

[0024] The probe body 4 is designed in a spindle shape, with pointed ends and a thicker middle. The shape of the probe body 4 has been redesigned. This spindle shape is conducive to the probe body 4 passing through the center of the flange at the pump pipe joint in the well. The internal structure of the probe body 4 is still designed using technology, and its specific structure will not be described in detail here.

[0025] like Figure 4-7 As shown, the telescopic protective assembly 6 includes a first tube 6-1, one end of which is connected to the protective cover 7. A second tube 6-2 is provided at the other end of the first tube 6-1, and a third tube 6-3 is provided at the other end of the second tube 6-2. The second tube 6-2 extends out of the first tube 6-1 and is positioned by a first connecting rod 6-7. The third tube 6-3 extends out of the second tube 6-2 and is positioned by a second connecting rod 6-8.

[0026] The outer diameter of the second tube 6-2 is smaller than the inner diameter of the first tube 6-1, and the outer diameter of the third tube 6-3 is smaller than the inner diameter of the second tube 6-2.

[0027] Two first connecting ears 6-4 are symmetrically connected to the top outer wall of the first tube body 6-1. A connecting ring 6-5 is connected to the top outer wall of the second tube body 6-2. Two second connecting ears 6-5-1 are symmetrically connected to the connecting ring 6-5, and the positions of the first connecting ears 6-4 and the second connecting ears 6-5-1 correspond to each other. The first connecting ears 6-4 and the second connecting ears 6-5-1 are provided with first mounting holes that match the first connecting rod 6-7. The upper and lower ends of the first connecting rod 6-7 pass through the first mounting holes and are locked in place by nuts. Two fourth connecting ears 6-6 are symmetrically connected to the top outer wall of the third tube body 6-3. Two third connecting ears 6-5-2 are symmetrically connected to the connecting ring 6-5, and the positions of the third connecting ears 6-5-2 and the fourth connecting ears 6-6 correspond to each other. The third connecting ears 6-5-2 and the fourth connecting ears 6-6 are provided with second mounting holes that match the second connecting rod 6-8. The upper and lower ends of the second connecting rod 6-8 pass through the second mounting holes and are locked in place by nuts.

[0028] In use, the second tube 6-2 extends from the first tube 6-1. The upper and lower ends of the first connecting rod 6-7 are inserted into the first mounting holes on the second connecting ear 6-5-1 and the first connecting ear 6-4, respectively. The nut is tightened at the end of the first connecting rod 6-7 to lock its position, thus keeping the second tube 6-2 extended. After the third tube 6-3 extends from the second tube 6-2, the upper and lower ends of the second connecting rod 6-8 are inserted into the second mounting holes on the fourth connecting ear 6-6 and the third connecting ear 6-5-2, respectively. The nut is tightened at the end of the second connecting rod 6-8 to lock its position, thus keeping the third tube 6-3 extended. This allows the telescopic protective assembly 6 to fully unfold, protecting the connection between the steel ruler cable 3 and the probe body 4, preventing the probe body 4 from being jammed by the flange at the pump pipe joint in the well during movement.

[0029] The third tube 6-3 is equipped with a filler 8 inside. The center of the filler 8 has a through hole 8-1 that matches the steel ruler cable 3. The filler 8 is made of elastic rubber, which wraps around the steel ruler cable 3 to protect it.

[0030] The steel ruler water level gauge includes a bracket 1, on which a winding reel 2 is rotatably mounted. A steel ruler cable 3 is wound on the winding reel 2. The end of the steel ruler cable 3 is fitted with the probe body 4. A fixing tube 5 is installed on the rear side of the bracket 1. When not in use, the probe body 4 is inserted into the fixing tube 5 to protect the probe body 4.

[0031] The working principle of the steel ruler water level gauge is that when the water resistance contact point of the probe body 4 comes into contact with the water surface, it connects to the receiving system, thereby triggering the sounder to emit a buzzer or illuminating an indicator light to determine the water level position. Its probe body 4, steel ruler cable 3, sounder, and peak indicator are all existing technologies and will not be described in detail here.

[0032] The usage process of this utility model is as follows:

[0033] Preparation: Before starting the measurement, it is necessary to ensure that all functions of the steel ruler water level gauge are normal; this includes checking the cleanliness and integrity of the steel ruler, and whether the scale on the dial is clearly legible; at the same time, a stable working environment should be selected to avoid the influence of surface vibration or liquid fluctuation.

[0034] Assemble the instrument: Fully unfold the telescopic protective component 6 to protect the connection between the steel ruler cable 3 and the probe body 4. Place the probe body 4 into the water level pipe, hold the steel ruler cable 3, and slowly move the probe body 4 downwards.

[0035] Turn on the power: Before measurement, loosen the locking screw behind the winding reel 2, allow the winding reel 2 to rotate freely, and then press the power button to light up the power indicator light.

[0036] Place the probe: Put the probe body 4 into the water level pipe, hold the steel ruler cable 3, and slowly move the probe body 4 downward.

[0037] Locating the water level: When the contact point of the probe body 4 touches the water surface, the receiver system's speaker will emit a continuous beeping sound. At this time, the steel ruler cable 3 should be slowly retracted or extended to carefully locate the exact position of the sound or indication moment and then read the depth of that point from the orifice.

[0038] Reading data: The accuracy of the reading depends on timely judgment of the starting position of the buzzer or indicator. The precision of the measurement is related to the operator's proficiency, so repeated practice and operation are necessary.

[0039] Turn off the power: After the measurement is completed, the power switch should be turned off immediately to save power.

[0040] Cleaning and storage: After measurement, the probe body 4 and steel ruler cable 3 must be wiped clean, and the steel ruler cable 3 should be neatly wound on the winding spool 2 and then placed in the cabinet.
