Abstract
The utility model relates to a running water pipe invisible leak alarm which is mounted inside a water pipe, two metal contacts (one is an elastic metal sheet and the other is a fixed metal sheet) are respectively mounted on two rubber sheets fixed on the pipe wall, the metal contacts are connected with power wires, and the power wires at two ends are connected with an alarm and an alarm control device. The alarm controller is equipped with a time switch, a voltage-stabilizing switch, an alarm controller, a signal discriminating recorder, a power supply and a signal detector which are connected with a power cord in series. Turning on the power supply when water is not needed, if the pipe is watertight, the two contacts are separated and the alarm device does not send alarm signals, if the pipe is leaked, two contacts are closed by water pressure generated by water flow and body pressure of the pipe, and then current can be conducted to enable the alarm mounted on the ground to send alarm light or sound.
Description
Technical field
The utility model relates to a kind of running water pipe and secretly fails to report alarm device, specifically is to utilize the pressure of water to make the power circuit closure, and secretly fails to report alarm device by the flowing water signal water pipe that sends alerting signal that judges whether to leak.
Background technology
Under the prior art condition, the maintenance of water pipe belongs to Running-water Company and is responsible for outside the water meter according to the rules, and the general water unit oneself of maintenance of the water pipe within the water meter (being commonly called as interior pipe) is responsible.The weight on of a specified duration excessively, ground of the time that water pipe row establishes, the sedimentation in house, weather etc. all may cause leaking of water pipe.The dark leakage of water pipe generally is invisible to the naked eye, and know whether water pipe has dark leakage that three kinds of methods are arranged: a kind of is artificial usefulness water rate payment card at the end of month, sees whether surpass normal water consumption; Second kind is by stopping all waters, seeing whether water meter is being walked; The third is to test with the leakage measuring instrument by sonic device.First kind can be owing to all departments of unit be less in linking up, and ignoring water consumption easily and judging water pipe by accident has dark leakage.Second kind of situation often can only be carried out at night, and operation neither be easily with accurate.The third is relatively more expensive with leakage measuring instrument by sonic device price, and general water unit can not buy these instruments.
Summary of the invention
The utility model has designed a kind of running water pipe and has secretly leaked alarm at above deficiency, and whether this device can accurately detect water pipe dark leakage, and simple to operate, and installation cost is also lower.
The technical scheme that the invention for solving the technical problem is taked: this device is installed on water pipe inside, (sheet metal is flexible for two hard contacts, another metal is fixing) be installed in respectively on two sheet rubbers that are fixed on the tube wall, hard contact links to each other with power lead, and the two ends power lead connects alarm and alarm control unit.Be provided with time switch in the alarm control unit, stabilized switch, alarm controller, signal is differentiated registering instrument, power supply, signal sensor and power lead polyphone.Opening power when unmanned water, if do not leak, these two contacts are that warning device does not separately have alerting signal; As leaking, current will form hydraulic pressure, add that the pressure of pipe itself makes this two hard contact closures, and electric current will circulate and make the alarm generation warning lamp or the sound of installing on the ground.This device cooperates the work of leakage detection signal sensor, when night during unmanned water, this warning device starts to work, when the leakage detection signal controller has detected water and has flowed, this detector closure, alarm controller is differentiated record after receiving signal, if discontinuous signal, can think at water, if continuous signal can be sent the sound and light alarm signal after the regular hour.
The beneficial effects of the utility model are can judge accurately by the alarm controller detection signal whether water pipe leaks, and the installation cost expense is relatively lower to be promoted easily.

2 contacts among Fig. 3,3 sheet rubbers, 4 alarms, 5 alarm control units, 13 power leads
Embodiment:
This device is installed in water meter 1 back in Fig. 1, two contacts 2 (a slice is elastic metallic hard sheet for fixing metallic hard sheet also has a slice) are arranged on the device, this two contact 2 be installed in respectively with the vertical sheet rubber 3 of water pipe on (this sheet rubber is fixed on the water pipe) and be connected alarm 4 and alarm control unit 5, when unmanned water, open time switch 7 and stabilized switch 8 among Fig. 2, if do not leak, two contacts 2 are that alarm control unit 5 does not separately have alerting signal among Fig. 1; As leaking, current will form hydraulic pressure, add that the pressure of pipe itself makes this two hard contact 2 closures, and electric current will circulate and make the alarm 4 generation warning lamp or the sounds among the Fig. 1 that installs on the ground.In Fig. 2, this device cooperates signal sensor 12 work, when night during unmanned water, this warning device starts to work, when alarm controller 9 has detected water and has flowed, and these signal sensor 12 closures, entering signal differentiation registering instrument 10 was differentiated record after alarm controller 9 was received signal, if discontinuous signal can think at water, if continuous signal after the regular hour by sending the sound and light alarm signal in Fig. 1 alarm 4.
The loss of water must cause the waste of China's water resource, and we answer using water wisely, and water pipe is carefully safeguarded in earnest.
