Description

The invention relates to devices with artificial flow for swimming, used for sports and medical purposes. The main purpose of such devices is to create conditions for swimming in relatively small structures, where the swimmer does not move forward, but remains in place due to the flow of water towards.

For such devices, it is important that the flow has the same speed in a certain volume, while the flow rate can be controlled. In this case, the best conditions for training athletes and comfortable conditions for therapeutic purposes are achieved.

Known solutions in which the water flow is created using various injection devices.

In the application of the Russian Federation 2001118689 "Swimming pool with artificial flow", E 04 N 4/00, publ. 06/27/2003 the pool contains a bowl, hydraulic screws are located in the walls of the bowl. In this device, the flow is chaotic and does not have the same speed in sufficient volume.

In US patent 4001899 "Device for swimming and therapy" E 04 N 3/16, publ. 01/11/1977 the flow is created by supplying water to the bowl through the holes using a pumping unit. Part of the bowl is fenced off to supply water flows from different directions and conduct water therapy. This device does not provide measures to create a water stream with the same speed in a sufficient amount. The device is characterized by a circulating system for water, which makes it quite complex.

In British patent 2296861 "Swimming pool with circulating water flow", E 04 H 4/12, publ. 07/17/1996 in the pool bowl with the help of a screw installed in the pool wall, in the middle, a central flow is organized in which swimming is carried out, and lateral oncoming flows, through which water returns and is again fed through the central flow. In this device, the central flow will not be uniform, in addition, the pool bowl should have a sufficiently large volume.

Closest to the claimed is the solution described in US patent 6151726 "Swimming pool", E 04 H 4/00, publ. 11/28/2000. This pool contains a tank with a channel for swimming and a second pressure chamber, in which using a pump unit creates a water level higher than in the tank for swimming. The pressure chamber is connected by a plurality of openings to the swimming tank. Artificial flow in the tank is created due to the difference in hydrostatic pressures in the pressure chamber and the tank. The water after the swimming tank is discharged into a separate tank, from where after filtration it returns to the pressure chamber.

Due to the fact that the pressure chamber and the swimming tank are connected by a plurality of holes, a water flow is created in the channel of the swimming tank at the same speed.

However, this device is quite complex, not adapted for transportation and installation in a new place.

In the claimed invention, the task of creating a swimming complex that can be mounted in any body of water or pool is easily disassembled, transported and collected, while during operation it provides a uniform flow of water in the required volume with the possibility of adjustment.

The inventive complex for swimming, which is installed in the water or in the pool, contains a housing with a flow channel formed by the side and lower walls of the housing, a pressure chamber connected to the housing from the entrance to the flow channel, a pumping unit for pumping liquid into the pressure chamber and system maintaining buoyancy of the body and pressure chamber.

The complex for swimming works as follows. Due to the mobility of the complex, it is delivered by vehicle and immersed in a pond or pool. Thanks to the system for maintaining the buoyancy of the hull and pressure chamber, it remains afloat and fixed in the required place of the reservoir. In the flow channel, since it is open at the exit of the channel, there is water that is contained in the reservoir. The pump unit pumps water from the reservoir into the pressure chamber and maintains a water level higher than the water level in the reservoir. The message of the pressure chamber and the inlet of the flow channel opens. A uniform flow of water is created in the channel, which leaves the flow channel again into the reservoir. An artificial stream of water is created in the flow channel, which serves to train athletes or improve swimming. The flow is uniform in cross section, as it is created due to the difference in hydrostatic pressures in the pressure chamber and the reservoir.

The main difference between the swimming complex and the previously known solutions is that it is installed in any reservoir or pool and does not contain a closed water circulation system. The flow of water in the flow channel where the swimming takes place is uniform in cross section and the flow rate is easily adjustable. The uniformity of the flow, as well as the possibility of its adjustment is achieved by the fact that the water flow is created due to the difference in hydrostatic pressure in the pressure chamber and the flow channel. The difference in hydrostatic pressures is created not only due to the water level in the pressure chamber, that is, the pump capacity, but also due to the regulation of the height of the body above the water level in the reservoir created by the buoyancy system of the body and pressure chamber.

In the particular case of execution between the pressure chamber and the entrance to the flow channel of the body, a system is installed that forms a flow in the flow channel, which can consist of a number of longitudinal and transverse wing elements. This system allows you to fine-tune the flow rate in any section, which is especially important for training athletes.

In addition, the aforementioned system, forming a flow in the flow channel, may contain nozzles connected to the gas supply system. Through nozzles, air bubbles are fed into the artificial stream of water, which provide a healing effect on the swimmer.

For fixing the complex in a pond or pool, the housing contains anchor devices.

In addition, the system for maintaining the buoyancy of the body and pressure chamber can be made with the ability to adjust the change in the depth of immersion of the flow channel, which allows you to adjust the flow rate.

The complex can additionally be equipped with a power supply and capacity control device of the said pumping unit, which allows to expand the ability to adjust the flow. With an autonomous power source, the complex can be used in any body of water, even where there is no power supply.

In order for the complex to be transported by various vehicles, the complex can be made collapsible.

The invention is illustrated by drawings.

Figure 1 shows a longitudinal section of the complex, figure 2 is a cross section. Figure 3 shows a section of the flow channel, while the system that forms the flow in the flow channel is equipped with nozzles for supplying air. Figure 4 shows the cross section of the flow channel with ledges.

The swimming complex (FIG. 1) comprises a housing 1 with a flow channel 2 formed by side walls 3 and a lower wall 4. A pressure chamber 5 is connected to the housing 1 from the inlet side of the flow channel 2. A pump unit 6 for pumping liquid into the pressure chamber into This example is installed in a partition. The system 7 for maintaining the buoyancy of the body and pressure chamber in this case consists of floats into which air is pumped.

The system that forms the flow in the flow channel, in this case, is made of longitudinal and transverse wing elements 8, made with the possibility of rotation around the axes. The wing elements 8 of the system forming the flow in the flow channel are installed at the inlet of the flow channel, but can also be installed at the output of the channel, which allows more precise control of the flow in the channel.

The wing elements 8 at the inlet of the channel are equipped with nozzles 9, which are connected to the gas supply system 10 through the gas manifold 14 and the air supply valves 15.

The housing 1 contains anchor devices 11 for unfastening the complex in the water area 13 or in the pool.

The pump unit 6 is connected to the device 12 power and performance control of the pump unit. Pump installation 6 may not be attached to the housing. An internal combustion engine can be used as a power supply device for the pumping unit.

The pressure chamber 5 is provided with an air bleed device 16.

The flow channel 2 to reduce energy costs for creating a stream may have the shape shown in Figure 4, or a shape with smooth contours. The shape and size of the cross section of the channel is determined by the radii of the sweeping of the swimmer's arms and legs.

The complex works as follows.

The complete assembly or in a disassembled state, including with a disassembled body 1, is delivered by a vehicle to a reservoir. Air is pumped into the floats of the buoyancy system 7 of the housing 1 and the pressure chamber 5. The assembled complex is lowered into a reservoir or it is collected in the water area. The complex can also be installed in collapsible swimming pools ranging in size from 3 to 5 meters.

Using anchor devices 11, the complex is detached in a pond.

The pump unit 6 is turned on and the pressure chamber 5 is filled with water from the reservoir. Air from the pressure chamber through the device 16 is vented to the atmosphere. Filled with water above the water level in the reservoir 13 or the pool, the pressure chamber 5 is connected to the inlet of the flow channel 2. A working pump unit 5 maintains the required water level in the pressure chamber 5, replenishing its flow rate. The necessary speed and direction of the water flow in different sections are regulated by the wing elements 8 of the system forming the flow in the flow channel 2. If necessary according to the training conditions, the gas supply system 10 is turned on, and air bubbles through the nozzles 9 enter the stream. If necessary, the flow parameters are adjusted by the wing elements 8 at the outlet of the flow channel 2.

Swimmer trains in the flow channel. The flow of water from the flow channel 2 again enters the reservoir.

After use, the swimming complex is removed from the reservoir, loaded onto the vehicle and transported to a new place of operation.
