Abstract

Provided are a spiral spring wire pulling liquid level measurement instrument and a measurement method thereof. A wave detecting tube higher than the highest liquid level is installed in a detected liquid medium, a floater is installed in the wave detecting tube, a spiral spring is installed in a spring box installed in an observation place, a wire wheel at the end of a spiral spring shaft is connected with the floater through a pulling wire, and when the liquid level of the detected liquid medium descends, the floater descends to drive the wire wheel to rotate through the pulling wire, and the spiral spring is tightened. An encoder or a gear transmission device is installed at the end of the spiral spring shaft, an encoder output is connected with an electronic display through an electric signal, and an output of the gear transmission device is connected with a mechanical reading table. On the contrary, when the liquid level of the detected liquid medium ascends, the floater ascends, the spiral spring takes up and tightens the pulling wire through the wire wheel, and the spiral spring shaft rotates to perform displaying of the electronic display or reading of the mechanical reading table through the output of the encoder or the gear transmission device as well. The spiral spring wire pulling liquid level measurement instrument is simple in structure, convenient to install, long in measurement distance, wide in application range and good in safety performance.

Description

technical field

[0001] The invention belongs to the technical field of measuring instruments, and in particular relates to a spiral clockwork spring wire pull liquid level measuring instrument and a measuring method thereof. Background technique

[0002] The closest prior art liquid level measuring instrument of the present invention and its advantages and disadvantages are as follows:

[0003] a. Alkaline float level gauge, advantages: high sealing, leak-proof, suitable for high humidity, high pressure, and corrosion resistance. Disadvantages: In direct contact with the medium, the floating ball has strict sealing requirements, cannot measure viscous medium, and alkaline materials can easily cause the liquid level to fail to work normally.

[0004] b. Alkaline flap (column) type liquid level gauge, the advantages are the same as above, but the disadvantages: the flap is easy to get stuck, resulting in failure to operate the indicator, and the alkaline material is easy to d...

Embodiment Construction

[0029] see figure 1 , figure 2 , the method for measuring the liquid level by the spiral spring wire of the present invention, install a wave reducing tube higher than the highest liquid level in the measured liquid medium, install a float in the wave reducing tube, install a spring box at the observation site, and install a spiral tube in the spring box Clockwork spring, one end of the spiral spring spring shaft is fixed with a wire wheel, the wire wheel and the float are connected by a pull wire, and when the float is at the top of the wave reducing tube, the float is held up at the top of the wave reducing tube when there is no gravity The tension of the spiral spring spring is the initial value; when the liquid level of the measured liquid medium drops, the float will naturally drop due to its own gravity greater than the tension of the spiral spring spring. The shaft of the mainspring spring rotates, and the helical mainspring spring tightens the helical mainspring spri...
