Description

The invention relates to the field of water supply, namely to the collection, storage, distribution of water, and relates to a reservoir for supplying drinking water in agricultural systems, as well as for uninterrupted supply of well water in country houses and rural buildings.

A device for collecting, storing, distributing water is known and relates to a reservoir for supplying drinking water in agricultural systems, as well as for small enterprises in temperate climates. The technical result is to increase the operational reliability of the tank in the cold season and to reduce ice formation in the middle and upper parts of the hull. The water storage tank includes a vertical cylindrical tank insulated in the lower part with soil sprinkling, water supply pipelines, including a water supply pipeline, the upper end of which is made in the form of a bend with an angle of 180 °, and the lower end is connected through pipelines to a submersible pump without a check valve . The specified pipeline and overflow pipe are located in the tank, while the upper end of the water supply pipe is placed above the overflow pipe, and the cylindrical part of the tank is made of plastic, for example low-density polyethylene (Patent for 2199629 IPC 7 Е03В 11/00).

A device is known - Bulgakov’s water battery (PSA), intended for use in a housing stock with uneven water supply during the day. The water battery contains a tank, a cold water supply pipe, a pipe for draining water and a pipe connected to the atmosphere. The tank is located vertically and is equipped with a level gauge, at the top there is a float and a removable lid, in the opening of which there is a pipe connected to the atmosphere. And the cold water supply pipe is connected to the tank through a flexible hose with a shut-off valve located in the upper part of the tank on one side and connected to a rubber nozzle for silent water intake into the tank. On the other side of the tank there is a pipe for water drainage. In the tank cavity there is a tube for emergency water drainage. To create a supply of water with a capacity of up to 250-300 liters in apartments, the PSA is equipped with a supporting metal table mounted on the floor above the toilet flush tank, on which the tank with a flexible hose for supplying water from the tank to the sink, bath and wash basin faucets equipped with a water meter and non-return valve (Patent for invention No. 2 116407 IPC 6 Е03В 1/04, 11/00, 11/02).

The disadvantage of this device is the ability to overflow the tank with water and the inability to ensure timely refreshment of water in the tank.

The purpose of the utility model is to prevent transfusion of water from the reservoir and to ensure timely water refreshment in it.

The goal is achieved in that the water tank contains a vertically arranged tank, pipes for supplying water, a pipe connected to the atmosphere, a float and a removable cover, a pipe for emergency drainage of water, an electric pump connected through a relay to a power source, and from below to a removable cover through brackets a pad with a hole is attached; a pipe is connected to the bottom of the hole with a float inside which contains a vertical rod with the possibility of regulating its length, the upper end of the rod is connected with an elastic rod with the possibility of regulating its size; a movable normally open contact pivotally connected to the contact pad and an elastic rod is placed above the hole above the hole; at the free end of the movable contact contains a permanent magnet; on the contact pad in the projection zone of the permanent magnet there is a fixed contact made of metal, the contact circuit is connected to the relay of the electric pump.

The figure shows a General view of the device.

The water tank contains a vertically arranged tank (1), pipes for supplying water (2), a pipe connected to the atmosphere (3), a float (4) and a removable cover (5), a pipe for emergency drainage of water (6), an electric pump ( 7) connected through a relay (8) to a power source (9), and from below to the removable cover (5) through the brackets (10), a contact pad (11) is attached to the hole (12); a pipe (13) is connected below the edges of the hole (12), inside which a float (4) is placed, containing a vertical rod (14) with the possibility of regulating its length, the upper end of the rod is connected with an elastic rod (15) with the possibility of regulating its size; on top of the contact pad (11) is placed above the hole (12) a movable normally open contact (16) pivotally connected to the contact pad (11) and an elastic rod (15); at the free end of the movable contact (16) contains a permanent magnet (17); on the contact pad (11) in the projection zone of the permanent magnet (17) there is a fixed contact (18) made of metal, the contact circuit (16, 18) is connected to the relay (8) of the electric pump (7).

The device operates as follows.

If the water tank (1) is empty, the float (4) located in the pipe (13) is in the lowest position; the elastic rod (15) under the influence of the float's gravity (4) carries away the movable normally open contact (16) until the permanent magnet (17) closes with the fixed contact (18). The relay (8) includes an electric pump (7), water through a tube for supplying water (2) enters the tank (1), forcing air out of it out through a pipe connected to the atmosphere (3). The permanent magnet (17) holds the movable and fixed contacts (16, 18) in the closed position. When the tank (1) is filled, the float (4) moves up the pipe (13) until the vertical rod (14) reaches the hole (12) in the contact area (11) and begins to disconnect the permanent magnet (17) from the fixed contact (18) ) A normally open contact (16), pivotally connected to the contact pad (11), moves to the open position, the electric circuit is open, water does not enter the tank.

As water is consumed, the float (4) sinks, gradually involving elastic traction (15). Elastic traction (15) at a predetermined immersion depth attracts the movable contact (16) to the closed circuit state, connect the electric pump (7) to the power source (9), fill the system with water. The placement of the contact pad (11) on the brackets (10) on the inner surface of the removable cover (5) provides a compact arrangement of the elements of the device. The emergency water drain pipe (6) is mainly used when adjusting the stroke value of the float (4).

The device provides the ability to adjust the upper and lower water levels, the frequency of water change in the tank. The normal functioning of the system does not allow overflow of water, provides an economical energy consumption.
