Description

The invention relates to the field of construction, namely the construction of water towers intended for local water supply, providing storage of regulating water supplies and maintaining the required pressure in the water supply network.

Water towers are used for water supply systems in small settlements, for industrial and fire-fighting water supply.

Known water tower (patent for invention RU 2 362 858 C1) consisting of a control tank, a water-holding support with pipelines, supply and discharge pipelines, in which an elastic separating diaphragm is built into the control tank of the tower, fixed in two points of the tank located opposite along the axis of symmetry of the diaphragm , and on the upper surface of the tank there is an air valve connected to the inner cavity of the tank.

The disadvantage of this water tower is the corrosion instability of the tower elements, a decrease in water quality, and the complexity of its maintenance and repair.

Also known is a water tower (patent for invention RU 2 446 262 C2), containing a drainage pipeline, the outlet of which is located in the lower part in the center of the water tower, and a water supply pipeline located tangentially to the circumference of the tower; a wind turbine with a vertical by a shaft passed through the cover inside the tower, at the lower end of which an activator impeller is fixed, while the direction of rotation of the shaft coincides with the direction of the water supply pipeline.

The disadvantage of the known water tower is the corrosion instability of the tower elements, a decrease in water quality, the complexity of its maintenance and repair.

The closest in technical essence to the proposed invention is a water tower A.A. Rozhnovsky (patent for invention SU 121555 A1), consisting of two vertically stacked cylindrical parts with different diameters, where the diameter of the upper part of the tower is greater than the diameter of its lower part - the barrel of the tower, interconnected by a conical transition, a control tank connected to the system water pipelines equipped with the necessary taps and valves, a control unit for water supply to the tank, a hatch and ladders for maintenance. As a result of the use of a water tower in the water supply network, there is a constant pressure, effective use of the tower tank capacity, this makes it possible, in addition to the regulating stock, to store a supply of water for fire-fighting purposes or other needs (in case of an accident of pumping units or a power outage). Taken as a prototype.

The disadvantages of the known solution are as follows:

- corrosion of the inner and outer surfaces of the tower, since the entire tower is made of steel;

- deterioration of the water quality in the tower tank due to contact with the inner surface of the tank that has undergone corrosion;

- deterioration of water quality due to the ingress of various contaminants and microorganisms from the environment into the tank, since the water in the tank has constant contact with the atmosphere;

- due to the constant contact of the pumped water with atmospheric air, the water is saturated with oxygen, which leads to increased corrosion of the internal elements of the tower;

- periodic cleaning of the inner cavity of the tower and constant monitoring of its sanitary condition is required.

The technical result of the invention is to eliminate the possibility of rust on the structural elements of the water tower, to reduce the costs of maintenance and repair of the tower, as well as to simplify its maintenance during operation, to protect the water in the water tower from atmospheric pollution, to maintain the water quality in the tower at the level of the incoming water quality. into the tower.

The above technical result is achieved by the fact that in the known water tower, consisting of two vertically stacked cylindrical parts with different diameters, where the diameter of the upper part of the tower is greater than the diameter of its lower part - the barrel of the tower, interconnected by a conical transition, a regulating tank connected with a water pipeline system equipped with the necessary taps and shut-off valves, a control unit for supplying water to a tank, a hatch and ladders for maintenance, the peculiarity is that both its cylindrical parts and the conical transition are made of composite material (fiberglass), and are connected between is a one-piece connection, while the upper cylindrical part is used as a control tank, which is hermetically sealed on both sides by hemispheres and is additionally equipped with an air carbon filter located on the upper hemisphere, and internal water level sensors, and the water piping system is located ena in the lower cylindrical part of the tower. The cylindrical parts and the conical transition can be glued together, for example, with glass cloth impregnated with resin. Each of the cylindrical parts is equipped with a hatch and a service ladder.

The water tower is made entirely from composite materials (fiberglass), all elements of the tower are interconnected by gluing with fiberglass impregnated with resin. All connections are one-piece. The upper part of the water tower has a coating in the form of a hemisphere, on which an air charcoal filter is installed, water level sensors are installed in the water tower tank, water is only in the tower tank, and the column remains "dry" for the possibility of servicing communications. The water tower is manufactured at the factory.

The invention is illustrated by drawings. Figure 1 shows a diagram of a water tower, which shows: tank - 1, tower barrel - 2, conical transition - 3, carbon air filter - 4, water level sensor - 5, hatch - 6, internal staircase - 7, fence - 8, external staircase - 9, water piping system - 10.

Figure 2 shows a volumetric view of a water tower.

The body of the water tower is completely made of composite materials (fiberglass). The tank (1) of the tower is made in the form of a cylinder closed with hemispheres on the upper and lower sides. An air carbon filter (4) is arranged in the central part of the hemispherical coating, which provides cleaning of the incoming air into the tank (1) when the volume of water in it changes. Inside the tank (1) of the water tower there are two water level sensors (5), one of which is at the level of the lower mark of the regulating water level in the tower tank, the second is at the mark of the upper design water level in the tank, giving signals to turn on and off the supply pumping stations. aggregates. In the upper part of the tank (1), a hatch (6) is arranged, which ensures the possibility of maintenance personnel getting into it. For descent into the tank (1), an internal ladder (7) is arranged on its inner surface. A fence (8) is arranged along the contour of the coating of the water tower for safe movement along the tank (1) of the tower, if necessary. On the outer part of the water tower, there is an external staircase (9) designed to lift the maintenance personnel to the water tower. For reliable fastening of the tank (1) and the barrel of the tower (2), they are connected to each other by a conical transition (3).

The barrel of the tower (2) is made in the form of a cylinder, in which a system of water pipelines (10) is located, connected to the tank (1). Inside the tower barrel (2) there is also an internal ladder (7) that allows you to climb to inspect the condition of the tower barrel (2) and the water piping system (10). On the barrel of the tower there is a hatch (6), which makes it possible for the maintenance personnel to get inside the barrel of the tower (2).

The proposed water tower works as follows - water coming from the pumping station fills the tank (1) of the water tower to the design level at which the upper water level sensor (5) is installed. When the tank (1) is filled to the calculated level, the water level sensor (5) sends a signal to the pumping station to turn off the pumping units. Water from the tank (1) of the water tower is supplied to consumers and when the minimum level in it is reached, on which the lower water level sensor (5) is installed, a signal is given to turn on the pumping units. Then the cycles are repeated. During the period of using water from the tank (1), its volume decreases, the released volume is filled with air entering the tank (1) through the air charcoal filter (4). The charcoal air filter (4) prevents contamination from the atmosphere from entering the drinking water.
