Description

The utility model relates to water supply and is designed to shut off the water supply in the event of water leaks in the water supply systems of residential, industrial, public and office buildings.

A device for automatic regulation of water and gas supply is known from the prior art (patent RU 137826, publ. 02.27.2014 Bull. No. 6), containing a control panel with a 220 Volt AC voltage to 12 Volt DC voltage converter with a backup power source and its function recharging, a radio signal receiving and transmitting unit, a valve and clockwork control unit, a water leakage sensor, safety shut-off valves made in the form of a normally closed electromagnetic valve installed on the water (gas) supply pipeline to the room, at least one control sensor, ensuring the actuation of safety shut-off valves, the control sensor is made in the form of a presence sensor installed in a room with a water-folding (gas-folding) fittings. The disadvantage of the device is the control of the device, depending on the readings of the motion sensors, configured in such a way that they are triggered only when a person approaches them directly. The motion detectors have a setting for the time interval of shutdown, during which they will work from the moment of the last detection of human movement from 5 seconds to an hour or more.

A device for shutting off the liquid supply is known (patent RU 76475, publ. 09/20/2008 Bull. No. 26), containing at least one shut-off valve installed on pipelines, configured to be triggered when liquid leaks are detected, containing at least one liquid sensor located on floor or mounted on a wall or on a pipeline in places where liquid is likely to appear, containing at least one control unit configured to issue a light and / or sound signal during emergency operation of the water supply network or heating, as well as issue an additional signal for other devices, when The shut-off valves are made in the form of a spherical electric drive, consisting of a ball valve and an associated electric drive, while the shut-off valves are electrically connected through at least one control unit with at least one liquid sensor. The disadvantage of this device is the presence of electronic sensors, which must be located in different places in the room, which in turn is not very convenient for some places where there may also be water leakage.

The closest in technical essence is a device for emergency shutdown of the water supply during abnormal operation of the water supply network (patent RU 2232852, publ. 20.07.2004 Bull. No. 20), containing a water fitting installed on the supply pipeline, in front of which there is a safety shut-off valve made with the possibility of operation in the presence of water leaks, has water presence sensors, each of which is made in the form of two open electrodes fixed on the floor and is located under the corresponding water fittings on the floor under the drain hole of the sink, washbasins, bathtub, shower, cistern, and a safety shut-off the fittings are made in the form of a normally open electromagnetic valve electrically connected through the control unit with the indicated sensors, and the supply pipeline is a common riser for supplying water to the room. The disadvantage of this device is the presence of electronic sensors, which must be located in different corners of the room, which in turn is not very convenient for some places where there may also be water leakage.

The general disadvantages of existing leakage control systems are:

- the use of magnetic elements or their components for the operation of the device, which are volatile, and in the absence of voltage in the system, these devices will not be able to function, and these devices also incur high operating costs and have a high cost;

- single structures with the pipeline, which does not allow dismantling or replacing the device;

- the use of wired and wireless sensors, which in turn may turn out to be useless in the event of a serious accident in the room, since they are small in size, for example, water can jet not in the direction of the sensor and rather strongly and far away, and before it hits the sensor already most of the room can be flooded;

- the use of ball valves, which have a high torque for turning the handle; ensure the occurrence of hydraulic shocks in the pipeline when the valve is quickly opened; it is necessary to open and close regularly (at least 1 time per week) to prevent the ball from sticking.

The problem to be solved by the claimed utility model is the development of a water leakage control device containing a minimum of parts, easy to handle and reliable during operation.

This problem is solved by the fact that the device for monitoring water leakage from under the filter flask includes a tray for collecting water, permanently connected to the upper plate, a switch with a button installed on the lower plate, permanently connected to the base, while the button is located on the middle plate, the top plate is made with the ability to move downward under the weight of the bath, thereby pressing the switch button, and the switch is electrically connected to the pumping station switching socket by means of a three-wire electrical connector, and the socket has a 220 V power plug. On the edges of the top plate there are guide clips for connections of the middle and upper plates. A screw is fixed on the top plate, which presses on the switch button when filling the bath with water. The device contains a sleeve that is put on the filter flask and is part of the bath.

The technical result provided by the given set of features is the expansion of the arsenal of water leakage control devices.

A device for monitoring water leakage from under the flask is used in plumbing units in everyday life at home.

The device for monitoring water leakage from under the filter flask includes a sleeve 4, a tray 10, upper plates 11, middle 12 and lower 17, base 14, switch 19 with button 20 and spring 15.

Sleeve 4 is put on the flask 2 of the water purification system 1 and fixed to the pipe 3 using straps 5 with fasteners inserted into the holes 6. On the flask 2, the sleeve 4 is tightened thanks to the side straps 7. The sleeve 4 is lowered into the tray 10 to collect water. The sleeve with the tray 10 constitutes a single structure. The sleeve is made of waterproof material, preferably polyethylene or oilcloth. The sleeve is necessary so that in the event of a leak, the flow of water is directed directly into the bath.

The tray 10 is a vessel shaped and sized to accommodate a flask. In this case, the flask should not touch the bottom of the tray. The bath 10 is permanently fixed to the upper plate 11 of the shutdown unit.

The shutdown unit includes plates upper 11, middle 12 and lower 13, base 14, switch 19 and spring 15.

A spring 15 is installed between the upper and middle plates. Spring 15 plays the role of throwing the upper plate into the upper position. At the edges of the upper plate 11, there are guide clips 18 for connecting the middle plate 12 and the upper plate 11, this is necessary so that the upper plate does not go to the side, since there is a bath on it and a spring presses from below. Also on the upper and middle plates at the edges there are holes for bolts 21, which serve to hold the upper plate and, as a result, work together with the spring when pressed down and return up to its original position. The lower plate is also connected at the edges by soldering to the middle plate by jumpers 17 on both sides. Switch 19, which includes a contact group with a capacitor, is located on the bottom plate. The bottom plate 13 is fixed to the base 14 or is part of it. The switch also contains a button, which, when filling the bath with water, is pressed by a screw 20 fixed on the top plate, thus turning off the pump.

The entire device can be installed on a base on the floor, or, in the case when the pipes are placed high above the floor, using a "swing" - the device is suspended from the pipe. The "swing" device is shown in Fig. 2.

The system for holding the device on the pipe ("swing") consists of a support 22 and a fastening system for which the support is suspended from the pipe. The fastening system includes a lower 24 and upper 26 metal rods. The lower rod passes through the hole 23 in the support 22. The metal rods are telescopic. At the ends of the lower rod 24, there are forks 25 for connection with the upper metal rods 26 through the connecting part of the rod 27. The fork 25 and the connecting part 27 have through holes into which the fastening element is inserted. This connection provides a swivel connection of the upper rods with the lower. For hanging the plate on the pipe, there are hinged fasteners 29, on which the handles 30 are installed, designed for the convenience of removing the device from the pipe. The base 14 has a cutout for the "swing" stand 22.

Switch 36 is a fused rocker switch. The switch itself is mounted on the bottom plate and the switch button is placed on the middle plate. Switch 36 of the device includes connection points 37 with the contacts of wires 34. Stranded wires for 220V are used for connection to avoid overheating. The switch of the device is connected to the socket for connecting the pumping station through the female-male 35 connector.

The electrical circuit of the device works as follows.

To get started, the device is connected to a 220 V power source with a plug 31 with a wire 34 for 220 V with three terminals (ground, phase, zero). Then a pump is connected to socket 32, which must be controlled. Further, a wire comes out of the socket 32, connected through an adapter mom and dad 35 (any adapter with three leads can be used), connecting the device to the switch button 36. An electric current is supplied to contact 37 from the plug 31 and when the button is turned on, the electric current goes to contact 38 , which in turn supplies power to the outlet and turns on the pump. In this case, the voltage is removed from the contact 38, which allows you to turn on the indicator light connected to the contact 39 through the capacitor 40, and thereby allows you to monitor the switching on of the device itself, since the button will light up. If the button is lit, then the device is normal and continues to control the pump, if the button is not lit, then the device is disabled and the pump has been turned off. This, in turn, prevents water leakage from under the flask.

The device works as follows.

When the faucet is turned on in the kitchen or bathroom, the pumping station is turned on, and at the same time water passes through itself under pressure, the water thereby passes through the purification system through the pipe and fills the flask, where there is a filter for water purification, also under pressure. At this point, the water pressure in the flask can cause water to leak from under the threaded connection, for example, due to depressurization or some other factor. Thus, the water breaks out, but it is retained and directed by the sleeve into the bath. Up to about 100 grams gets into the bath, depending on the pressure of the water breakthrough. The tray fills slightly, gives some weight and presses on the on / off button located under the top plate. Then the button turns off, thereby turning off the pumping station, and the water stops flowing. To drain the water that has entered the bath, you must first disconnect the pump from the mains and turn off the device (where the connector has a mom and dad connection), then remove the device from the flask down and drain the water. The sleeve can be completely disconnected from the system for convenience and remove the flask, fix the ring and screw it back (the same must be done at the moment when you just need to change the water filter). Next, screw the flask and install in reverse order, first the sleeve, then the device. After making sure that everything is installed correctly, first turn on the mom and dad connector, and then the pumping station itself into the network.
