Abstract
The utility model relates to a high-low water level alarm device being able to alarm that the water level is high or not. The alarm device comprises a transformer L, a controlling circuit, a guide tube, a coupled rod and a floating body. The utility model is characterized in that the guide tube is positioned in a water sump. The floating body is positioned in the guide tube. The floating body is fixedly connected with the coupled rod. The touching rod of the coupled rod is caused to be respectively matching and touching-provided with a touching switch SK1 and a touching switch SK2 in a controlling circuit. The opening and closing of a water pump can be automatically controlled. The alarm device has a simple structure, the high practicality and the high reliability. The utility model can open or close the pump automatically according to the water level size of the water sump and ensure the requirement of the water level of the water sump. The utility model also can ensure the safety of the electrical appliance under a mine.
Description
Affiliated technical field
The utility model relates to a kind of alarm, the especially a kind of high-low water alarm instrument that can just report to the police to water level.
Background technology
At present, the draining in main drain pump room under the coal mine is how with driver's walkaround inspection on duty or determine switch water pump rule of thumb, can not guarantee effective water capacity of sump, in case it is full and do not have not turn on pump the storehouse to occur, will cause serious consequence, also not very tube list and practical and reliable solution at present.
Summary of the invention
For the problem of the timely switching on and shutting down of water pump that solve the main drain pump room, the utility model provides a kind of high-low water alarm instrument.This alarm is simple and practical, and good reliability can carry out the switch pump according to the water level size of sump automatically, can guarantee the requirement of water bunker level.
The scheme that its technical matters that solves the utility model adopts is: this alarm comprises transformer (L), control circuit (6), guide pipe (5), trace (2) and buoyancy aid (3) five parts, it is characterized in that: in sump (4), be placed with guide pipe (5), be placed with buoyancy aid (3) in the guide pipe (5), be fixedly connected with trace (2) on the buoyancy aid (3), the touch pole (1) of trace (2) respectively with control circuit in touch switch SK
1, SK
2Coupling is touched and is installed.Get final product the Push And Release of automatically controlled water pump.
Its beneficial effect is: owing to adopt such scheme, make that this alarm is simple in structure, practical, good reliability, can carry out the switch pump according to the water level size of sump automatically, can guarantee the requirement of water bunker level.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is a structural principle synoptic diagram of the present utility model.
Among the figure, 1 touch pole, 2 traces, 3 buoyancy aids, 4 sump, 5 guide pipes, 6 control circuits.
Embodiment
In the drawings, this alarm has in the control circuit (6), and it is by transformer L supply 36V safety low-voltage, and electric current is through the resistance R voltage stabilizing, through light D, electric bell L
1, switch S K
1Form closed circuit, during high water stage, touch switch (1), the conducting electric current is inhaled moving pump switch K
1Closure, electric current are got back to another utmost point of transformer (L), and water pump begins drainage works.
In the drawings, when low-water level (d), touch pole (1) descends, touch switch SK
2Closure, current lead-through makes K switch 2 closures, K
1Disconnect, formed a utmost point, resistance R, light D, alarm bell L, the switch S K of a transformer
2, K switch
2And the closed circuit of another utmost point of transformer, water pump quits work.Sump water full pumping is opened, and anhydrous pass pump can guarantee that sump remains anhydrous state, can guarantee the security appliance under the mine.
In the drawings, guide pipe (5) is a straight tube that internal diameter is smooth, and sliding fit is equipped with the buoyancy aid (3) that is lighter than water in its internal diameter, and buoyancy aid (3) can slide up and down flexibly.
In the drawings, K
