Description
Technical field
This utility model is related to the fixed point leak water detdction of a kind of machine room and other watertight areas.
Background technology
In existing water leak detectors, based on the line that leaks hunting, test point is needed two or more, at a distance of long situation
Under, cost, waste of resource can be increased significantly.The line that leaks hunting laying is relatively cumbersome, need to avoid conductor, otherwise report by mistake.
The content of the invention
For the deficiency in structure in prior art, the purpose of this utility model is to provide a kind of fixed point water leak detectors,
Filling pipe end or leakage point, simple installation can be directly placed at.Relay signal output is more accurate.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of fixed point water leak detectors, the inspection
Survey device and include box body, wherein：The power supply indicator being connected with power supply is provided with the top of the box body, in the box body
Bottom be respectively provided on two sides with multiple spy points, be provided with wire hole on the one side of the box body；Leak hunting on another side rope
Wiring hole；Bottom in the box body is fixed with master control borad, be provided with master control borad be connected with each other LM393 comparators, after
Electrical equipment, adjustable resistance, described each spy point, power supply indicator, wire hole are electrically connected with master control borad.
Fixed point water leak detectors effect of the present utility model be in the case of monitoring fixed point leak, the relative rope that leaks hunting should
With cost is lower, and it is more accurate to judge.The product that leaks hunting in the market is various and expensive, substantially all more than thousand yuan, and
Based on the rope that leaks hunting, but for some environment, and the monitoring of leak scope is not needed, such as machine room, workshop etc., like environment leakage
As long as water spot is seldom monitored in leakage point and be capable of achieving monitoring effect, certainly will cause to waste with the water leakage monitoring on market,
This utility model fixed point water leak detectors cost is compared with the thousand of units on the market products that leaks hunting, is greatlyd save only in dozens of yuan
Cost.And only needing to pinpoint in the environment for leaking hunting, this utility model fixed point water leak detectors are installed in possible leakage point, in report
It is easier to find leakage point when alert.LM393 comparator sensitivities are adjustable, improve the accuracy of warning, in order to avoid false alarm.And
Still the rope accessory that leaks hunting can be matched, enters line range monitoring, the suitability is wider.

Specific embodiment
Fixed point water leak detectors structure of the present utility model is illustrated with reference to accompanying drawing.
As shown in Figure 1,2,3, 4, fixed point water leak detectors of the present utility model, the detector includes box body, described
The side of box body is provided with the power supply indicator 1 being connected with power supply, is provided with multiple spy points 2 in the opposite side of the box body,
The one side of the box body is provided with wire hole 3；The line interface 4 that leaks hunting is provided with described box body another side；In the box
LM393 comparators, relay, adjustable resistance are included in vivo, and are integrated on one piece of master control borad, described each spy point, power supply
Display lamp 1, wire hole is electrically connected with master control borad.
During using fixed point water leak detectors of the present utility model, powered by outside DC12V power supplys first, and connect power supply instruction
After lamp 1, power to master control borad, LM393 chips and relay work.Point 2 is visited when water leakage situation is detected with, point 2 is visited and is soaked,
Resistance between the detectable signal of master control borad+- the two poles of the earth can reduce.In the same manner, it is also optional to connect the rope that leaks hunting, leak inspection is carried out to region
Survey, if leaking hunting rope immersion, the resistance between signal+- the two poles of the earth can reduce.After LM393 comparators are compared, to relay
Device signal, analog quantity can be changed into the output of switching signal Jing relay, you can produce alarm signal and exported by wire hole 3.Its
Middle adjustable resistance can adjust sensitivity, the i.e. threshold values of LM393 comparators.
Fixed point water leak detectors of the present utility model, network computer room or other require the room and region of waterproof, place
, in the case where there is leak, there is effective signal output in one fixed point water leak detectors.And if it is desired to leak is carried out to region
Detection, can match the general rope that leaks hunting being of convenient length, and possible leak region is disposed, the effect of area monitoring is reached,
Access leak hunting rope interface 4, detection sensitivity is adjustable.It is stainless steel to visit point 2.Integrated design, small volume are convenient to install.
Fixed point water leak detectors technical parameter of the present utility model：
Power supply：DC 12V；
Output：Relay is exported；
Relay peak load：Alternating voltage maximum 250V, alternating current maximum 10A
DC voltage maximum 30V, DC current maximum 10A；
Response time：<1S；
Sensitivity：Built-in adjustable (built-in-potential device is adjusted)；
Box body：ABS white 99mm*68mm*49mm, compartment；
Core component：LM393 comparators, working stability.
Fixed point water leak detectors of the present utility model, with model F8 as box body, it is ensured that detector itself does not have immersion event
Barrier.One adjustable potentiometer is adjusting detection sensitivity.Bottom has 4 No. 304 rustless steels to visit point 2, ensures detection accuracy.
Integrated design, it is easy for installation.
The mode of connection：It is 4*0.5 shielded signal lines in 3 lead-out wire of wire hole.Four cores are respectively：It is brown, blue, red, yellow.
Palm fibre：Input DC 12V+
It is blue：Input DC 12V-
It is red：Relay output NO (NC is adjustable)
It is yellow：Relay exports COM
Fixed point water leak detectors are placed on the leakage point that need to be detected.Note：4 are visited 2 ends of point downwards, and are placed on
In idioelectric plane.
Brown, blue by lead-out wire is connected after DC 12V+-, and Chang Liang is represented normal work by power lights.If detected Lou
Water, relay will export make-and-break signal.
