Description

The invention relates to construction, namely to facilities for training and training rowers. The invention can also be used for entertainment purposes in the form of an attraction in water parks and recreation areas.

A pool is known for training swimmers with a closed flow channel, in which a hydraulic pump is installed that creates a directed water flow in the pool, controlled by the swimmer through an associated sensor that controls the flow rate in the pool by changing the speed of the pump (SU 187577 A, publ. 11/21/1966). Known pool for training rowers, made bunk, and containing in the upper tier two channels of ovoid cross-section, communicating with each other through the middle section to accommodate the boat. In the lower tier there is a pneumatic turbine to create water circulation. To fix the boat in place, shock absorbers are used, located in the bow and stern of the boat (SU 1006682, publ. 03.23.83; SU 1526207, publ. 07.12.89).

Known devices create a constant flow rate, and hence a constant load for the athlete. To regulate the flow rate, sensors are used, mounted on oars and electrically connected to the drive of the device that creates the water flow.

For example, a pool is known (SU 1437048, publ 07.12.89, prototype) made of two tiers and containing in the upper tier two channels of ovoid section for placing oars, communicating with each other through the middle section for placing a boat, hingedly mounted on the border of the channels of the diaphragm of a two-lobed shape of an ovoid type , a means for creating water circulation in the lower tier, and controllable flow dividers installed at the boundaries of the tiers, made in the form of throttle valves, characterized in that in order to increase the efficiency of training and reduce energy costs, hydraulic accelerators are placed in the bottom layers of the channels, each of which is made in in the form of propellers sequentially installed on the shaft with flow guides between them in the lead of streamlined bodies of revolution. At the same time, the regulation of the flow rate occurs under the influence of the transmission of signals from sensors installed on the oars to the drives of the hydraulic accelerators and the means for creating water circulation, located in the lower tier

This device requires the construction of capital structures and uses a complex mechanism for regulating the operation of devices that create a circulation flow. At the same time, the boat is fixed in place, which differs from the real process of rowing on open water and does not allow the rower to practice the methods of controlling the boat in the stream.

The technical result is a simplification of the design, providing the ability to regulate the load on the athlete without changing the mode of operation of the pumps, as well as providing the opportunity to practice the skills of controlling the boat in the water flow.

The technical result is achieved by the fact that the rowing pool, containing a means for creating a constant circulation of water, according to the invention, the pool of an elongated shape is made of a flexible material, and contains a flat bottom and sides bent upwards on the sides and ends of the pool, inflatable floats are fixed along the edge of the sides , connected to the bottom by flexible connections, from the outside to the edge of the bottom and the middle of the side boards, sheets of flexible material are fixed, forming external containers that run the entire length of the sides and are closed by end sheets, holes are located in the sides at the location of the outer containers along the entire length of the pool, some of which have plugs, holes are made in the front ends of the outer tanks, to which the suction pipes of the pump are connected, and the discharge pipe of the pump has a rectangular section and a curved profile that envelops the front wall of the pool.

In Fig.1. presents a section of the pool along the longitudinal vertical plane, figure 2 plan of the pool, figure 3 is a cross section of the pool.

The pool consists of a sheet of flexible material, including a flat bottom 1, sides 2 bent upwards, inflatable floats 3 connected to them along the upper edge, connected by flexible connections 4, with a bottom 1, side tanks 5 made of sheets of flexible material connected to the edge of the bottom 1, and the middle part of the sides 2, and plugged with end sheets 6, in the lower part of the sides 2 there is a row of holes 7, some of which are closed with plugs 8, holes are made in the front ends of the tanks 5 connected to the suction pipe 9 of the pump 10, the pressure pipe 11 of the pump 10 is made flat section and curved profile, enveloping the front side of 2 pools.

The device works as follows

The pool is laid out on an arbitrary horizontal platform. Before starting work, the floats 3 are filled with air using a compressor, then the pool is filled with water. In this case, the water raises the floats to the tension of the bonds 4. Due to the pressure of the water, the sides 2 acquire a convex shape. At the same time, through the holes 7, water enters the containers 5, which, under excessive pressure, also straighten out and acquire a given shape. At the same time, the suction pipes 9 and the impeller of the pump 10 are filled with water. After that, the pump 10 is turned on, and water begins to flow into the pool through the pressure pipe 11. In this case, the water level in the initial section rises and the water begins to move along the basin. At the same time, in the initial section of the side tanks 4 connected with the suction pipes 9 of the pump 10, the piezometric water level decreases and the water begins to move along the tanks to the pump. In this case, due to the difference in the level in the pool and the piezometric level in the side tanks 5, water will begin to flow from the pool into the side tanks 5 through the holes 7. The flow rate will decrease towards the end of the pool since the level in the pool will decrease, and the piezometric level in the tanks 5 increase due to resistance to water movement. Thus, the flow rate in the pool in the initial section will be maximum, and as you move away from the initial section, the flow rate, and hence the flow rate, will decrease. By adjusting the number of open holes 7 along the length of the pool with the help of plugs 8, it is possible to set the required mode of changing the flow rate along the length of the pool. This allows the rower in the boat to move against the current. At the same time, the closer the boat moves to the beginning of the pool, the more forces the rower will need to keep the boat in line. The rower himself will be able to regulate the load and quickly change it without changing the operating mode of the pump, which will constantly operate in the most efficient design mode.
