At present, water level alarm is of a great variety, but most function singleness is not considered alarm occurrence positions circumstance complication, distance position on duty may be far away etc. problem, general adaptability is not strong.Especially level switch part-structure complexity is unfavorable for long-term, stable, the effectively work of equipment.White stone reservoir gallery is provided with sump, and sump percolating water is completely back by the automatic draining of submersible pump.When dirt obstruction or equipment malfunction, comprise that the submersible pump of stand-by pump stops pumping, can cause gallery to be poured water, the accident of other facility, equipment in the damage gallery takes place.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly is fit to be installed under the complicated environmental conditions such as darkness, humidity, and post on duty is far away apart from the accident occurrence positions, and has the water level alarm of mandatory protection function.It is simple in structure, widely applicable, adaptability is strong, with low cost, is convenient to make, install, and is convenient to inspection, maintenance and management.
Water level alarm of the present utility model comprises probe 1, control enclosure 2, alarm 3, and its special character is:
The stainless steel 14 that described probe 1 is enclosed in stainless-steel tube 11 upper port by the stainless-steel tube 11 that is provided with surperficial air hole 12, admittedly constitutes, and contact A, B are drawn in the end of stainless-steel tube 14 and stainless steel 11;
Described control enclosure 2 is by series connected battery group 21, dry-reed relay KR, power switch 23, with contact A, the probe lead wire end that B links to each other, three utmost point thyristor VT and be connected on the gate pole of three utmost point thyristor VT and the reset switch between the anode 22 is formed, dry-reed relay KR coil pin is connected with electric battery 21, first terminals 24 of drawing to be connected with the alarm dc power anode at the switched pins of described dry-reed relay KR and the gate pole of three utmost point thyristor VT, the normally closed pin of described dry-reed relay KR is drawn second terminals 25, the pin of often opening of dry-reed relay KR connects the negative electrode of three utmost point thyristor VT by current-limiting resistance R, and the anode of described three utmost point thyristor VT and the node of reset switch 22 are drawn the 3rd terminals 26;
Green relay indicating light 32 between the direct supply 31 that described alarm 3 is linked to each other with control enclosure first terminals by positive pole, second terminals that are connected on direct supply 31 negative poles and control enclosure 2, the red alarm pilot lamp 33 and the hummer 34 that are connected on direct supply 31 negative poles and control enclosure the 3rd terminals are formed.
When this water level alarm used, described probe was installed in water level control line position, and described control enclosure is installed near the eminence of workplace, and described alarm is installed in the duty room of far-end.
Under the normal condition, the change type dry-reed relay in the control enclosure is not worked, and the green relay indicating light of alarm is long bright in the duty room.When the workplace water level floods probe positions above the water level control line, the stainless steel contact of probe is connected, make the change type dry-reed relay field coil in the control enclosure produce magnetic field, tongue overcomes elastic force and another often opens the reed closure, green relay indicating light extinguishes, the red alarm pilot lamp is lighted, and hummer is started working.
The utility model compared with prior art has following beneficial effect:
1, the utility model is with low cost, is easy to make and install;
2, sonde configuration is simple, checks easily, safeguards, false alarm can not take place or install malfunctioning situation;
3, the electric routing battery group of probe and control enclosure composition provides low-voltage DC, under environment such as darkness, humidity, can not cause the safety problem of workplace personnel or equipment;
4, post on duty can be arranged on apart from workplace than distant positions, and alarm uses direct supply, and power supply is convenient;
5, have mandatory protection function, after triggering is reported to the police, even water level returns to below the control waterline, still keep alarm condition, after clicking reset switch, just can sound all clear.
