Abstract
The invention discloses a portable water level gauge comprising a lower shell (1) and an upper shell (2). A water inlet (3) is arranged at the bottom of the lower shell (1); a float (4) is arranged inside the lower shell (1); a permanent magnet (5) is inlayed on the top of the float (4); an exhaust hole (6) is arranged on the upper part of the cavity where the float (4) locates; the lower shell (1) is connected with the upper shell (2) through a thread (7); a reed pipe (8) is arranged on the lower part of the upper shell (2); a contact of the reed pipe (8) as a start switch is connected in a circuit which comprises a twin-core sheath lead (9), a switch (14), a cell (15), a light emitting tube (15) and a buzzer (16); when the float (4) floats upwards in water, the reed pipe (8) controls the start circuit under the magnetic field of the magnet (5); and an acousto-optic prompt is sent to read the water level scale value on a cable (8).
Description
Affiliated technical field
The present invention relates to a kind of floodometer, especially be applicable to the portable floodometer of water resources management department measurement inspection well water level.
Background technology
In recent years, along with human production activity's reinforcement, more and more to phreatic exploitation, the geological problem of Yin Faing is subject to people's attention thus, very necessary to phreatic daily monitoring, therefore should provide a kind of usefulness, portable floodometer of being simple and easy to for relevant departments.
Chinese patent instructions 200920072042.0 discloses a kind of dip meter.The probe of this floodometer is by plastic outer tube, pipe in the stainless steel, two sealing-plugs of shutoff stainless-steel tube constitute two sealing baffles of following float chamber, transition chamber and last float chamber and are positioned at two spherical magnetic floats that are enclosed within on the stainless-steel tube of float chamber and last float chamber to constitute.When probe entered in the water, following float and last float successively started the tongue tube on bottom and top, and water level is read in indication.Though this measuring instrument can be measured water level more conveniently, the complex structure of its probe, the more and difficult processing of parts, higher during actual production to technological requirement, be unfavorable for the product manufacturing.
Chinese patent instructions 200920098487.6 discloses another kind of motor-pumped well floodometer.The sonde configuration of this floodometer is simple, and probe is made of last lower house, and its inside has only transfer wire, and when probe entered in the water, the bare exposed conductor that water touches transfer wire formed the loop, and water level is read in the start-up circuit prompting.But its problem simple in structure of this measuring instrument is to utilize the exposed part of transfer wire to meet water whether as the condition of circuit start, this is insecure under many circumstances, for example the borehole wall of some well can drip even flowing water, these water enter probe probably and cause wrong report, all very moist in the well in addition, the environment of this humidity can make insulation resistance significantly descend, and also can cause the floodometer misoperation.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of portable floodometer of reliable operation simple in structure.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the bottom at the lower house of level measuring instrument probe has water inlet, be provided with float in the lower house, when probe enters in the water, float upwards floats, for guaranteeing that float floats rapidly reliably, top at float place cavity has vent port, discharge the air that hinders the float come-up, the top of described float is provided with permanent magnet, bottom at upper shell is provided with tongue tube, when float floated near described tongue tube, the magnetic field of described permanent magnet made the contact action launching indicating circuit of tongue tube, and hummer in the circuit and luminotron send acousto-optic hint simultaneously, read the number of division on the cable this moment, can obtain the water level of being surveyed.
As a further improvement on the present invention, described lower house and upper shell adopt the stainless steel manufacturing, when it is characterized in that preventing to get rusty, also make probe have suitable weight, do not need to join tup in addition and keep vertical can make cable go into well the time for this probe, the transition of described upper shell shoulder chamfering is not stuck when guaranteeing to propose probe from well.
As another improvement of the present invention,, further fix with heat-shrink tube and protection twin-core RVV on the top of upper shell at inner waterproof material filling fixedly tongue tube and the twin-core sheathed conductor used of described upper shell.
The invention has the beneficial effects as follows that level measuring instrument probe simple in structure is easy to clean and safeguard, probe moves up and down in well flexibly during use, is difficult for being stuck the reliability height.
Description of drawings
The present invention is further described below in conjunction with drawings and embodiments.
Accompanying drawing is a structural representation of the present invention.
1. lower houses among the figure, 2. upper shell, 3. water inlet, 4. float, 5. permanent magnet, 6. vent port, 7. connecting thread, 8. tongue tube, 9. twin-core sheathed conductor, 10. upper shell shoulder chamfering, 11. heat-shrink tube seal grooves, 12. heat-shrink tube, 13. circuit assemblies, 14. switches, 15. luminotrons, 16. hummers.
Embodiment
From embodiment of the present invention shown in the drawings as can be known; the diameter of the water inlet 3 of lower house bottom is less than the external diameter of float 4; it is little that a volume is inlayed at the top of float; powerful magnet 5; the bottom of upper shell is provided with a tongue tube 8; the two ends of tongue tube link to each other with two leads of twin-core RVV respectively; with the waterproof and sealing material filling tongue tube and twin-core RVV are fixed in the upper shell then; the reusable heat draw puts the top of twin-core RVV and upper shell; further fix and protection twin-core RVV, circuit assembly 13 is contained in the cable drum.
Rotate cable drum during use probe is put down along well head, float come-up after the probe entry is when the magnet on the float during near tongue tube, the closing of contact start-up circuit of tongue tube, send acousto-optic hint, read the number of division on the cable this moment, can obtain the water level of being surveyed.
