Description

The invention relates to the field of sports, entertainment and attractions. The simulator allows you to simulate situations in which a person experiences physical exertion de facto and is forced to respond to them, performing the same actions as in a real workout.

The present invention is intended for use in inertial simulators described, for example, in patents RU No. 85094, AV 22/00, publ. 07.27.2009 and 83929, A63B 21/00, publ. 07/27/2009, which are designed to create real physical sensations on the crest of a "standing wave" for a surfer.

So, for example, in RU No. 85094, an inertial simulator is described which comprises a housing rotatable by an engine with a drive providing variable rotation speed and reversal; the housing is made in the form of a lower part of the torus and is mounted on supporting wheels, at least one of which is connected with the drive of its rotation, an elevator shaft with doorways mounted through the center of the platform is mounted to lift the user to the platform, and a carousel is fixed to the elevator shaft, which is made with retracts of movement in the radial direction relative to the body of the slings intended for attachment to the user, while the body is made with the possibility of filling with water and flowing through collectors connected by pipes, one of which is mounted in the upper part of the body wall along the perimeter of the latter, and the other at platforms.

And RU No. 83929 describes an inertial simulator containing a platform on the axis, driven into rotation by an engine with a drive that provides variable rotational speed and reversal, the housing is located under the platform and is made in the form of the lower part of the torus, in the center of which is the axis of the platform surrounded by the platform with an inclination to the axis, while the housing is connected with an axis rotation drive, the axis of the platform is made in the form of an elevator shaft with doorways for lifting from the platform to the platform, and the body is configured to fill with water and etoka through its interconnected pipe collectors, one of which is mounted in the upper part of the housing wall and the other at the site.

This decision was made as a prototype.

In well-known simulators, autovisual and muscle loads on an athlete are achieved when moving around a circle, when inertia acts on the body. The creation of a "centrifugal force" causes a physical sensation, for example: movement on a mountain slope for a snowboarder, or on water for a surfer. She seeks to throw his body away from the center, and the further the athlete is from the center, the more he will pull and tilt him out. This creates the illusion that he is standing on an inclined plane. If water is poured onto such a surface, then it spreads in an even layer. The body of the simulator, filled with a certain volume of water, simulates a mountain slope during rotation, or a crest in the form of a sickle-shaped month, or the water surface. The athlete is forced to take actions: muscular efforts to lay bends, inclinations to fix the center of gravity of the body in space, etc., as a reaction to the conditions created by the simulator, simulating the selected environment. The work of the simulator is based on the presence of inertial forces of rotation, creating a field of centrifugal forces, which, due to the selected configuration of the casing, gives the water surface the required curvature.

The disadvantage of this method is that in the framework of training, real conditions cannot be achieved in which the athlete will have to perform certain technical methods. This is due to the fact that when the hull rotates, water forms a relatively flat surface on the wall of the hull, which corresponds to the calm state of the water surface of the sea (ocean). The outflow of water through the pipelines of the collector system does not allow waves to form on the surface, and even more so waves that would allow training in a dynamic mode, close to the real state of the sea water surface.

The technical result that can be obtained by implementing the proposed device is to increase the effectiveness of training by creating the effect of a “standing wave” on the water surface of the body of an inertial simulator, which will allow to develop coordination of movement and statokinetic noise immunity of an athlete to external force exposure in real conditions that repeat the conditions of the training sports competition.

The specified technical result is achieved by the fact that in the method of generating a wave in an inertial type of water attraction, which consists in rotating a body filled with water with an inner wall surface in the form of a paraboloid of revolution or in the form of a lower part of a torus for distributing an aqueous layer along this body wall, forming a wave on the surface the specified aqueous layer is formed by installing on the surface of the wall of the body of the bulges in the form of spirally elongated ribs.

These features are significant and interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present utility model is illustrated by a specific example, where the drawing shows an inertial-type simulator device.

The present method of creating a wave in inertial type of water attractions is considered on a specific example of such a simulator.

The inertial simulator is a vertical centrifuge consisting of a housing 1 connected to the engine 2 via the axis of rotation 3. In turn, the engine 2 is connected to the axis 3 through a variator 4 and a reverse 5, which allow the housing 1 to rotate at a variable speed and in opposite directions. The housing 1 of the simulator is supported through a system of rollers 6 located on a circle on rails. A platform 7 is made at a certain height in the center of the simulator case. On the platform 7, the trunk of the elevator shaft 8 with the doorways 9 is mounted strictly in the center. The elevator shaft 8 does not rotate with the platform 7, which ensures the athlete can safely move from the supporting surface 10 to the platform 7 or to overlap 11 (traverse). The body of the simulator is the lower part of the torus with the formation of a torus concave surface, which is filled with water. The water mirror in the stationary position is indicated by pos. 12. When the simulator rotates, water is distributed over the torus surface, occupying in the dynamics the position indicated by pos. 13. Along the perimeter of the housing 1, in its upper part is a collector 14 for collecting excess water. Around the platform 7, a collector 15 with nozzles is located around the perimeter, which supplies water to the torus cavity. The collectors 14 and 15 are interconnected by overflow pipes 16, which are located not along the meridians, but in a spiral both to one and the other side, which allows for a natural flow of water between communicating collectors 14 and 15 due to the karyolis inertia. This water circulation system includes a water treatment system, and, if necessary, a pump unit and a water heating device.

The overlap 11 can be made in the form of a carousel mounted on the shaft, to which traction halyards 17 are attached (for example, with kite fasteners) through a movable carriage 18 (for moving the halyard radially around the carousel, in the radial direction relative to the body), connected to the carousel, which will allow the athlete move along the entire torus (mountainous) surface of the housing 1. The axis rotating the carousel can be made coinciding with the vertical central axis of the housing or offset relative to the vertical central axis of the housing (can be found sya not at the center of platform 7). The carriage 18 takes position “X” in the unloaded form, and under the weight of the athlete takes the maximum position “U”.

The main idea of the simulator is to create autovisual and muscle loads on the athlete, which is achieved when moving around the circle, when inertia acts on the body. The main task is to create a "centrifugal force", which by its action causes a physical sensation, for example: movement on a mountain slope for a snowboarder or on the crest of a "traveling wave" for a surfer.

Consider the rotational movement of the flat platform on which the athlete is located. She seeks to throw his body away from the center, and the further the athlete is from the center, the more he will pull and tilt him out. This creates the illusion that he is standing on an inclined plane.

If you give the rotating platform such a curvature that at a certain speed its surface is at each point perpendicular to the resulting (resultant forces), then the person will feel at all its points, as on a horizontal plane. If water is poured onto such a surface, then it spreads in an even layer.

Consider the drawing three characteristic points of the body of the simulator, rotating in the likeness of a vertical centrifuge.

At point "A" the effect of sliding down is ensured, since the weight force in the composition of the resulting forces is dominant. At point "B" the effect of sliding to the periphery and down is ensured. Between them is a boundary point, where the resultant of forces is perpendicular to the surface of the housing 1, where the effect of being on a horizontal surface appears.

The body 1 of the simulator, filled with a certain volume of water, simulates a mountain slope or a crest of a "traveling wave" in the form of a crescent month during rotation. The athlete is forced to take actions: muscular efforts to lay bends, inclinations to fix the center of gravity of the body in space, etc., as a reaction to the conditions created by the simulator, simulating the selected environment. The work of the simulator is based on the presence of inertial forces of rotation, creating a field of centrifugal forces, which, due to the selected configuration of the casing, gives the water surface the required curvature.

A feature of such a simulator is that its design features allow the formation of waves simulating waves in the sea on the water surface in the hull. This effect is obtained as follows.

We bring into rotation with constant angular velocity around the vertical axis the housing 1 in the form of a bowl or lower part of the torus, filled with some volume of water. In this case, the casing should have the shape of a rotation paraboloid, so that when the paraboloid rotates with the liquid around the vertical axis with a certain angular velocity, water will be distributed on its surface with a thin layer of almost constant thickness. This will happen when the vessel rotates around the vertical axis, when the liquid experiences an acceleration of the portable movement directed towards the walls of the body, then the resultant of two forces (gravity and centrifugal force) will be directed normal to the free surface of the liquid at each point on the surface. Hence: the free surface of the liquid, located in a vessel uniformly rotating around its vertical axis, will have the form of a paraboloid of revolution. Therefore, the water attraction has the form of an elliptical paraboloid, and the difference in levels on the periphery and in the center of the paraboloid, relative to the horizontal surface, forms a “standing wave” of considerable height.

The effect of the "traveling wave" is enhanced by giving the inner surface of the rotating vessel ribbing in the form of convex spirals such as convexity 19. spirally stretched along the wall of the housing. Depending on the direction of rotation of the attraction, the characteristics of the "standing wave" change. With leading spirals, the standing wave is lower, but deeper, and vice versa with lagging spirals. The wave effect is formed due to the flow of water through an obstacle from the bulges. Since the bulges are spirally arranged, a visual sensation of a “standing wave” is created.

To organize the movement of the water flow along the inner rotating surface of the body from the bottom up (which enhances the similarity of the artificially created "standing wave" with the ocean), you can use the previously described water circulation system. The water circulation system is designed in such a way that water flowing over the perimeter of the attraction along the perimeter collects in the upper collector and flows through the pipes into the lower collector, from where it in turn flows into the attraction's internal cavity. During the rotation of the casing, water formed a free surface in the form of a paraboloid, and the difference in levels relative to the horizontal surface means only the same statistically equal pressure at any point on the free surface. And if there is no pressure drop, then it can be created artificially by backwater from the lower manifold. For the movement of the water layer on the inner surface of the housing from the bottom up, it is necessary to organize the selection of water from the upper collector with its flow through the pipes into the lower collector. This is achieved by arranging the pipes connecting the collectors in the form of spirals. To obtain the opposite effect, i.e. water directions on the inner surface of the rotating housing from top to bottom, the pipes are arranged in the order of lagging spirals. Well, if the overflow pipes are placed along the meridians, then the water circulation system will not work. Reducing or increasing the curvature of the spiral due to the displacement of the ends of the pipes relative to the collectors (the pipes are not rigid), as well as the use of shut-off and control valves, will make it possible to evenly distribute water throughout the entire inner surface of the casing even when its surface is made in the form of a snail (one part turn screw). If necessary, the discharge of water to the inner surface of the housing can not be provided evenly, depending on the planned trick or obtaining the desired effect, namely, by regulating the flow of water from the pipes using shut-off and control valves, namely by increasing or decreasing the water supply to the surface area of the working surface corps.
