Abstract

The utility model discloses a kind of rack-mounted water leakage alarm devices, including detection cable and detection host, the detection host can be used for pure water leak detection and the interior sensitivity for having adjusting knob, can changing detection host by adjusting knob, allow it is suitable for various environment.

Description

A kind of rack-mounted water leakage alarm device

Technical field

The utility model is related to a warning devices for detecting whether leak, are particularly suitable for the leak inspection of computer room It surveys.

Background technology

Most of water-leakage alarm that the suitable computer room of current market offers uses all is soft by computer Part realizes that computer has the accuracy that the machine of delaying, detection probe have the factors affects such as corrosion detection, alarm computer power consumption High and wiring complexity cannot be flexibly installed in each cabinet；Other non-computer formula water-leakage alarms cannot centralized and unified pipe Reason, it is impossible to detect the pure water such as air conditioner condensate water.

The content of the invention

Stop response to solve existing water-leakage alarm software based on computer software, computer delay machine the deficiencies of and Non-computer formula water-leakage alarm cannot be managed collectively, it is impossible to the shortcoming of pure water is detected, the utility model provides a kind of alarm, The alarm is not related to computer based on simple electronic circuit, can not only detect pure water, steady in a long-term to run, low in energy consumption, can Networking centralized management and it is small can be used for cabinet panel install.

Technical solution is used by using the invention for solving the technical problem：Linear water logging detection cable passes through multiple twin Line is connected with detecting the input port of host, and when there is liquid to touch detection cable, the resistance for detecting cable changes.It is this Variation is transmitted to detection host by twisted-pair feeder, and detection host is analyzed according to pre-setting for its internal circuit, triggering leakage The rule of water is so as to triggering warning circuit.Detection cable is that high molecular material is corrosion-resistant, high sensitivity；Host is detected by LM393 Integrated circuit, buzzer, LED light and resistance capacitance composition, system stability is high, and power consumption is extremely low.

Using technical solution provided by the utility model, compared with existing known technology, the utility model has as follows Advantageous effect,

1. the input of the utility model, output and power supply are completely isolated, the power supply of 5-12V DC power supplies；

2. the utility model leak water detdction sensitivity multi gear is electrodeless adjustable；

3. the good antistatic of the utility model, Anti-surging technology ensure the reliability service of product；

4. the utility model alarm standby power is less than 0.2W, alarm power is less than 0.8W；

5. the utility model scene audible and visual alarm simultaneously can access other type of alarms such as short message；

6. the utility model apparent size：480*88*38mm is conveniently used for cabinet panel installation；

7. design is scientific and reasonable for the utility model, simple and ingenious structure, convenient for fabrication and installation, effect stability is reliable, so as to So that making is low with the cost of working service, be conducive to promote.

Specific embodiment

With reference to Figure of description, the utility model is described in detail.

Water logging detection cable described in Fig. 5 is placed to position and the fixation of leak to be detected, detection cable passes through multiple twin The detection cable interface of line and Fig. 2（6）Connection；By the DC outputs of 5V power supplys and the power interface of Fig. 2（5）Connection, stirs Fig. 1's Power switch（4）Make alarm in running order, at this time the power supply indicator of Fig. 1（2）It is always on；In water logging cable described in Fig. 5 Upper a few drop distillation Fluid Dynamics pure water leakage environment of drop adjust the sensitivity switch of Fig. 4（9）Allow the buzzer of Fig. 4（10）It is long Ring and Fig. 1 in status indicator lamp（3）Flicker.Alarm is passed through into the installation screw of Fig. 1 Fig. 2（1）It is fixed on cabinet, Complete the installation and debugging of whole system.

Claims (2)

1. a kind of rack-mounted water leakage alarm device, including detection cable and detection host, it is characterised in that：Described Detection host can be used for pure water leak detection and it is interior have adjusting knob, by adjusting knob can change detection host it is sensitive Degree, allows it is suitable for various environment.
