Abstract
The utility model relates to a liquid detector with magnetic induction which belongs to the measuring instrument class, and the utility model is a detector used for detecting the depth of the liquid level and the liquid. The inner of a float of the utility model is provided with a magnetic ring, and a probe is provided with a dry reed pipe. When the dry reed pipe goes into the magnetic field scope of the magnetic ring in the float, the position of the liquid can be determined by the alarm of a signal device. The utility model has simple structure, convenient measurement, and high precision test. The utility model is mainly used for observing the dynamic of the ground water, and can measure the liquid level depths of variety liquids whose density is smaller than 3*10000 kg /stere, environmental temperature is not lower than-40 DEG and not higher than 80 DEG.
Description
The utility model belongs to the surveying instrument class, is the detector of a kind of detection of liquid level and liquid depth.
Existing level sensor, mainly contain " magnetic force liquid level gauge " (number of patent application is 88218650.7), it is the improvement to the fluid level gauge of old-fashioned magnetic force liquid level gauge, (number of patent application is 89208769.2 to also have " magnetic dry-reed tubular type liquid level sensor ", ball float and sounding rod that it adopts combination magnet ring and magnetic shielding to constitute are formed, the former exists sensitivity and precision lower, and the latter's structure is more complicated again.
The purpose of this utility model provides a kind of simple in structure, easy to carry, is mainly used in a kind of magnetic induction liquid probe that underground water (or other liquid) dynamic observes.
The technical solution of the utility model is: it is made up of probe and signalling means.Probe is by cursory (5), guide pole (2), magnet ring (6), tongue tube (4), weight-adding hammer (8), shell (3), lead (1) is formed, the structure of probe is, center in shell (3), adorning guide pole (2), in the guide pole (2), fixing tongue tube (4), lead (1) is housed on the tongue tube (4), lead (1) is connected with signalling means, outside the guide pole (2), suit cursory (5), cursory can sliding up and down along guide pole (2), in cursory (5), adorning magnet ring (6), shell (3) is with guide pole (2), cursory (5) etc. are encapsulated in it front end of shell (3), adorning the weight-adding hammer that front end is a cone (8), signalling means is the battery of installing by in housing (13) and the housing (12), acoustic alarm device (11), light warning device (12) is formed.
The bottom of shell (3) has the top of inlet opening (7), shell (3) that vent port (9) is arranged.
Cursory (5) are the hollow buoyancy aids of being made by plastic material.
Lead (1) is the twin-core shielding line.
Guide pole is to be made by antimagnetic material.
The acoustic alarm device can be water chestnut doorbell or electronics buzzing sheet.
The light warning device can be a light emitting diode.
The utility model is simple in structure, and it is convenient to measure, and the measuring accuracy height can be not less than-40 ℃ to the liquid of density less than 3 * 10000 kilograms per cubic meter in environment temperature, be not higher than+80 ℃ of conditions under, carry out the dark measurement of liquid level and liquid.

Fig. 2 is the signalling means synoptic diagram
Below in conjunction with embodiment the utility model is further described.
Embodiment 1: measuring liquid level, to pop one's head in vertically downward, put into to fluid to be measured, when probe contacts liquid level and inserts liquid, liquid enters in the shell (3) by inlet opening (7), according to law of connected vessels, liquid level in the shell (3) and tested liquid level are at grade, fluctuate along guide pole (2) with the lifting of liquid level cursory (5), when probe drops to the tongue tube that makes in the guide pole (2) and is positioned at the magnetic field range of magnet ring (6) of cursory (5), circuit is just connected, and the acoustic-optic alarm of the signalling means of top dress is just reported to the police the electric bell sounding, lumination of light emitting diode, can record liquid level, liquid level can be determined by the degree of depth that lead (1) is lowered to tested liquid level, also can pass through counter, digital display shows.
Embodiment 2, measure liquid depth, at first measure liquid level according to the method for embodiment 1, take out probe then, unclamp being connected of weight-adding hammer (8) and shell (3), again dark head is put into liquid, cursory in the shell (3) is in shell (3) under the liquid effects, rise to the upper end of shell, continue to put into probe, shell (3) at first touches at the end, continue to put down probe, shell is motionless, and weight-adding hammer moves down relatively, moves to the weight-adding hammer front end and touches the end, tongue tube is positioned at the magnetic field range of magnet ring in guide pole, circuit is connected, and just can record position at the bottom of the liquid, and liquid depth equals position at the bottom of the liquid, deduct liquid level position, add the distance (the mark zero line that be shell to weight top distance) of tongue tube to the weight-adding hammer top.
