The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1, the water heating leakage monitoring device provided by the utility model comprises a detection module and a signal sending module 100 which are connected by electric signals. The detection module comprises a relay J, a triode VT, a resistor RH and a detection cable B, wherein one end of a control end of the relay J is connected with a collector of the triode VT in series, and the other end of the control end of the relay J is connected with a power supply; the emitter of the triode VT is grounded; the resistor RH is connected in parallel between the base electrode and the emitter electrode of the triode VT. The detection cable B is connected between the power supply and the base electrode of the triode VT. The signal sending module 100 is electrically connected with the normally open contact and/or the normally closed contact of the relay J, and sends a preset alarm signal to a fire-fighting host after receiving the normally open and/or normally closed switching value signal input by the relay J.
The working principle of the monitoring device is as follows: when the detection cable B is immersed in water, the resistance of the detection cable B is reduced due to conductivity of water, so that the triode VT is in a state that the base voltage is higher than the emitter voltage and the collector voltage is lower than the base voltage, and at the moment, the triode VT is conducted and the relay J is attracted. After the relay J is attracted, the normally open contact and/or the normally closed contact of the relay J send a switching value signal to the signal sending module 100, the signal sending module 100 is triggered after receiving the switching value signal, and sends a preset alarm signal to the fire-fighting host for alarming, wherein the preset alarm signal can comprise an address code corresponding to the monitoring device and is used for identifying the position of the monitoring device, so that a manager can quickly locate the position of a leaked radiator, and the maintenance is convenient and timely.
In specific implementation, the key of water leakage detection is to adopt a proper layout mode to effectively detect water leakage points. After comprehensively considering the layout modes of points, lines and surfaces, the detection cables B are laid on the proper positions of the ground near the lower part of the radiator in the factory building in a straight line state, the purpose of regional monitoring and alarming is achieved, and the water leakage detection speed is greatly improved.

The detection cable B is provided with annular openings 110 with a second preset length at intervals of the first preset length, and the copper cores 120 in the detection cable B are exposed from the annular openings 110. The circular cut openings 110 on the two detection cables B are staggered by a third preset length.
For example: BV wires with the length of 2.5mm 2 are selected, the insulating layer is cut into an opening with the length of 1cm every 10cm, the cut positions of the two treated BV wires are staggered by 1cm and are laid on the ground near the lower part of the radiator in parallel, the distance between the detection wire B and the orthographic projection position of the radiator on the ground is about 5 cm, as shown in fig. 3, when the leakage of the radiator under different conditions is ensured, the first time is detected by the detection wire B, and false alarm is avoided.
Two BV lines which are arranged at intervals in parallel are adopted as the detection cable B, and the advantage is lower cost. However, the copper wire undergoes electrolytic reaction after meeting water, so that the copper core at the annular cutting position is corroded seriously due to the electrolytic reaction, and the copper wire cannot achieve the effect of long-term use and needs to be replaced frequently.
Second kind: and the detection cable B is a water leakage induction rope. The water leakage induction rope is provided with two induction wires which are arranged at intervals in a spiral winding mode, one end of one induction wire is connected with the power supply, and one end of the other induction wire is connected with the base electrode of the triode VT.
When the water leakage induction rope is contacted with water, two induction wires on the water leakage induction rope are short-circuited, so that current change occurs. The water leakage induction rope is only needed to be adopted in the prior art. Its advantages are high mechanical performance, high corrosion and abrasion resistance, and repeated use. The disadvantage is the relatively expensive price.
In this embodiment, the resistor RH is an adjustable resistor. The resistor RH can adjust the signal collection sensitivity, so that the problems of repeated actions of the critical point of the relay and misoperation caused by ground moisture can be prevented. Specifically, the higher the resistance of the adjustable resistor, the higher the sensitivity of the overall monitoring device.

In this embodiment, the signal transmitting module 100 may select two modes of wired transmission and wireless transmission according to the distance between the signal transmission distances:
First kind: if a wired transmission mode is adopted, the model of the signal transmission module 100 is GST-LD-8300.GST-LD-8300 is fire alarm system input module that bay safety limited company produced, GST-LD-8300 type input module is used for receiving the normally open or normally closed switching value signal that fire control linkage equipment input to pass linkage information back fire alarm system ware.
Second kind: if a wireless transmission mode is adopted, the signal transmission module 100 includes a single-chip microcomputer and a wireless module, and the wireless module is electrically connected with the single-chip microcomputer through a signal. The model of the wireless module is NRF24L01, the air transmission distance is about 100 meters-150 meters, and the highest speed is 10MHz. The structure of which is shown in fig. 5.
