Description

The proposed utility model relates to sanitary-technical water supply systems for residential and public buildings, containing a pressure head water supply pipeline with an extensive network of individual consumers (washbasins, showers, etc.) equipped with water-folding fittings.

One of the problems of these systems is the possibility of flooding with water from the water supply network through water fittings, since the latter is not equipped with devices for emergency shutdown of the water supply during abnormal operating modes of the water supply network, or has such devices, but they have low reliability.

A device is known for emergency shutdown of the water supply during an abnormal mode of operation of the water supply network, containing water-folding fittings installed on the supply pipe, in front of which safety shut-off valves are installed, made with the possibility of actuation in the presence of water leaks (AS USSR No. 1484887, IPC E03C 1 / 00, published on June 7, 89, BI 21).

The disadvantages of the known device are: the complexity of the design, the bulkiness and material consumption of the device, inconvenience in operation and maintenance, as well as limited functionality (lack of shut-off of the water supply when the tap is left open).

A device is known for emergency shutdown of the water supply during an abnormal mode of operation of the water supply network, containing water-folding fittings installed on the supply pipe, in front of which safety shut-off valves are installed, which can be activated in the presence of water leaks. It additionally contains water sensors, each of which is made in the form of two open electrodes fixed to the floor and located under the corresponding water fittings on the floor under the sink drain hole, sinks, bathtub, shower, drain tank, and the safety shutoff valves are made in the form of normally open an electromagnetic valve electrically connected through the control unit with the indicated sensors, and the supply pipe is a common riser for supplying water to the room (see patent RF №2232852 from 13.05.03 cells E03C 1/242 -. Prototype).

A disadvantage of the known device is the low reliability and efficiency due to the lack of the ability to remotely control the system.

The objective of the proposed technical solution is to eliminate these shortcomings and increase the efficiency of the device, including due to the presence of remote control capabilities in it.

The problem is achieved in that in the device for emergency shutdown of the water supply, containing a water fitting, in front of which a safety shut-off valve is installed, including an electromagnetic valve, a control unit configured to operate in the presence of leaks, a water presence sensor, according to the invention, a water presence sensor equipped with a radio transmitter having the ability to generate a radio signal when a water sensor is triggered, and the control unit is equipped with a receiver for this the signal and is configured to supply a control action to the electromagnetic valve upon receipt. In addition, the control unit is located on the solenoid valve, and the radio transmitter is made in the form of a mobile telephone communication device.

A comparative analysis of the device with the prototype and with other solutions in the art shows that the set of features described is unknown from the existing level of technology, on the basis of which we can conclude that it meets the criteria of the invention of "novelty."

The compliance of the proposed solution with the criterion of the invention "industrial applicability" can be seen from the following example of a specific implementation of the device for emergency shutdown of the water supply during abnormal operation of the water supply network.

The utility model is illustrated by a drawing, which schematically shows a General view of a device for emergency shutdown of the water supply, where:

1 - supply pipeline;

2 - water folding fittings (crane);

3 - the electromagnetic valve;

4 - control unit;

5 - water availability sensor;

6 - radio transmitting device;

7 - a radio signal receiver;

8 - power supply.

The device for emergency shutdown of the water supply contains a supply pipe 1 with water-folding fittings (faucet) 2, in front of which a safety valve (normally open solenoid valve 3) is installed, a control unit 4, to which a water presence sensor 5 is connected (two open electrodes). The power supply to the control unit 4 is made from two sources: both from the power supply unit 8, operating from an alternating current network 220 V, and from the battery, made with the possibility of recharging from the power supply unit 8. Sensor electrodes 5 are installed on the floor of the room under the drain hole of the water-folding fittings (by crane) 2 or in any other place where water may appear during abnormal operation of the system.

The sensor 5 is equipped with a radio transmitting device 6, and the control unit 4 has a radio signal receiver 7 capable of receiving the radio signal of the radio transmitting device 6.

The operation of the device is as follows. In the operating mode of operation of the plumbing system, its operation is carried out in the usual way, and the electromagnetic valve 3 is in the open position. That is, for the supply of water, the valves are opened (faucet) 2, and to stop it, the faucet 2 is closed.

In the event of an emergency that threatens to flood the room (leaving the water tap open, breaking it, breaking the water pipe, etc.), water begins to get on the floor of the room. The water entering the electrodes 5 causes a short circuit

the latter, which will be a command to the radio transmitting device 6, which, in turn, turns on and sends the radio signal received by the receiver 7 located on the control unit 4. Having received the radio signal, the control unit 4 gives an impulse to close the electromagnetic valve 3, blocking the water flow to the side faucet 2. As a result, water is saved and rooms are protected from flooding by water from the water supply network.

In the case of using a mobile communication device (mobile phone) as the radio transmitting device 6, the signal from it, in addition to being received by the receiver 7 located on the control unit 4 (which causes the electromagnetic valve 3 to overlap), can also be received on the mobile phone of the owner of this premises (for example, as an SMS message) and / or to the central emergency service (after which the recipients of such information will take measures appropriate to the current situation). This technical solution is especially effective in conjunction with a general emergency security system, when the used mobile communication device is functionally connected to the security alarm system, and both systems work on one transmitting device.

Thus, the use of the proposed device will improve the reliability of the system and reduce the negative consequences of emergency situations.
