Description
Technical field
The present invention relates to water-level alarm technical field, more particularly to a kind of water level alarm.
Background technology
Water-level alarm sensor uses solid state sensor, for detecting the presence of conducting liquid, such as water spilling, water receptacle water
Position, blowoff basin etc., position alarm sensor have two stainless steel electrodes, can be arranged on the point that detect liquid.When detecting liquid
When, relay closes in alarm water level, and the signal can be used for audible alarm or close the switch of remote monitor device.wa600
The relay of water-level alarm sensor is isolated entirely, can load 2a electric current.
But existing water level alarm is directly carried out in use there is in place of some shortcomings to water surface elevation
Water level acquisition, the water surface have certain unstability, cause height of water level collection to have certain error, secondly can not realize remote
Journey terminal alarms, so can not meet the demand of user.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of water level alarm proposed.
To achieve these goals, present invention employs following technical scheme：A kind of water level alarm, including water tank, institute
State water tank lower inside and be provided with ball float, and ball float is fixedly connected by pressure inductor with fixed mount, water tank side table
Water-level alarm case is fixed with wall, audible-visual annunciator, the water-level alarm case are fixed with the housing of the water-level alarm box top
Inside be fixed with signal receiver, and signal receiver is fixedly connected by wire with PLC, the PLC
It is fixedly connected respectively with memory, control alarm, long-distance alarm apparatus and indication display by wire, the pressure sensor
Output end and signal receiver input be electrically connected with, the input of the output end and PLC of the signal receiver
End is electrically connected with, and the output end of the PLC is shown with memory, control alarm, long-distance alarm apparatus and instruction respectively
The input of device is electrically connected with.
As further describing for above-mentioned technical proposal：
The output end of the control alarm and the input of audible-visual annunciator are electrically connected with.
As further describing for above-mentioned technical proposal：
Connecting rod is welded between the water tank of the fixed mount.
As further describing for above-mentioned technical proposal：
The fixed mount is hollow structure inside.
As further describing for above-mentioned technical proposal：
The long-distance alarm apparatus passes through LAN and terminal control warning device wireless connection.
In the present invention, the water level alarm, the pressure change that water tank inner float ball is sensed using pressure inductor are carried out first
Water level depth detects, in contrast to traditional direct water level alarm being monitored to water surface elevation, the water level alarm for
Water level detecting is more accurate, is not easily susceptible to wobble effects, improves the accuracy of its alarm, is secondly provided with alarm case remote
Journey alarm, long-distance alarm apparatus pass through LAN and terminal control warning device wireless connection so that the water level alarm may be used also
To realize that remote terminal is alarmed, it is used enhanced convenience, memory is provided with last water-level alarm case, can be by PLC
The water level signal that controller receives is stored, and is provided with indication display, and PLC can be received to water level signal conveying
To indication display, by indication display connection on a display screen, the waterlevel data for being easy to people to get information about.
