Abstract

The invention relates to devices for simulating physical phenomena, and more particularly to devices for generating waves suitable for training in water sports, for example water skiing, surfing, etc., in indoor and outdoor pools. The technical result of the invention for which patent protection is sought is to produce a standing wave, the body of which has a lower speed of longitudinal flow travel than in known devices, reaching a minimum in the region of the crest of the wave, which significantly improves its attractiveness to users and causes the resulting wave to more closely resemble a wave formed under natural conditions at sea in an area where the sea or ocean floor rises gradually toward the shore, while at the same time making it possible to adjust the parameters of the wave in order to achieve optimal characteristics for each specific case (for example, specific wave parameters for sportsmen and women of different levels, novices, children, adolescents, etc.). The present device for generating an artificial wave comprises a first channel, a second channel with a constant cross section, and a turbine-driven water pump that connects the first and second channels via adapters which adjoin the inlet of the first channel and the outlet of the second channel to the outlet and inlet of the turbine-driven pump respectively, wherein the first channel has a curved outlet portion and the outlet of the first channel is adjoined to the inlet of a convergent nozzle, said inlet being downwardly inclined in a direction away from the outlet of the first channel, and the interior space of the nozzle being delimited by an upper adjustable plane and a lower plane adjoined at a convex angle to a first edge of a first bottom plane that is downwardly inclined in a direction away from the nozzle, a second edge of said first bottom plane smoothly adjoining a first edge of a concave bottom surface, a second edge of which is hingedly adjoined to a first edge of a deflector, transitioning into a bottom plane at a right angle, while a bottom plane of the deflector transitions into a niche situated below the deflector and containing a hydraulic cylinder capable of controlling a change in the angle of inclination of the plane of the deflector, a second side of the niche below the deflector adjoining a first side of a second bottom plane, a second edge of which terminates abruptly in a water collector, the outlet of which adjoins the inlet of the second channel, wherein the space of the water collector is delimited by a lower flat wall, the lower edge of which smoothly adjoins the lower edge of the second channel, wherein the device has an open space that is delimited at one end by the upper plane of the nozzle and at the other end by a second edge of a horizontal wall of the water collector, and the first and second channels, the nozzle, the water collector and also the open space are delimited at the sides by two substantially parallel vertical walls, and the device is provided with a protective perforated bottom which is arranged with a downward incline from the water collector toward the deflector and is fastened to the second bottom plane, to a vertical wall of the water collector and also to the aforementioned vertical walls.

Description

DEVICE FOR FORMING AN ARTIFICIAL WAVE

FIELD OF TECHNOLOGY

The invention relates to a device for simulating physical phenomena, and in particular to a device that provides the formation of waves suitable for training in water sports, for example, water skiing, surfing, etc. in indoor or outdoor pools.

LEVEL OF TECHNOLOGY

The following solutions are known from the prior art.

Known is a wave generating device configured to be centrally located within a pool of water and comprising at least one actuator configured to activate at least one water displacement environment to displace water so that waves propagate through the water; and guiding means configured to direct waves from the wave generating mechanism after actuating the actuator so that waves propagate outward from the wave generating mechanism in different directions; and a water collection system adapted to circulate water in a circle to the wave generating mechanism from the perimeter positions inside the container back towards the wave generating mechanism (RF patent N ° 2592935, published 07/27/2016).

A device for generating an artificial wave is known, including a pool, an inclined surface, an outlet located in the center of the pool and directing water in a unidirectional flow up the inclined surface by means of a pump located in a sump under an inclined surface and directing water to the outlet located at the lowest point an inclined surface, while the device is configured to resume wave delivery when the user approaches the outlet to re-raise the user to the upper region of the inclined surface to re-descend the user (US patent N ° 5738590, published 04.14.1998).

The closest analogue of the patented solution is a device for generating an artificial wave, including a bottom inclined up the length of the pool, defining the deep edge and edge of the shore. The wave generator is located near the deep edge. An open undulating slit is located near the edge of the beach and is adapted to retain water. The device is designed in such a way that when the wave generator is not activated, water is retained in the pool, which determines the static water level, and part of the shore edge is above the static water level. When the wave generator is energized, it creates a wave that travels through the wave pool from the deep edge to the shore, and the wave energy is extinguished when the wave collides with the water remaining in the trough (US patent application N ° 2018106058, published 04/19/2018).

The disadvantage of the known solutions lies in the fact that in the known devices the wave crest is created by a flow (flow) of water moving by gravity, and the flow created has the properties of a laminar flow, in which particles predominantly move in layers, without mixing and without pulsations. In other words, the movement is even, without erratic jumps in pressure, direction and speed, which does not correspond to the natural waves used in training, for example, surfing.

DISCLOSURE OF THE INVENTION

The technical problem solved by the invention is to create a wave, the properties of which are as close as possible to the waves encountered in natural conditions.

The technical result of the patented invention is the formation of a standing wave crest, which has a lower than in known devices, the speed of longitudinal movement of the flow, reaching a minimum in the region of the wave top, which significantly improves consumer properties and brings the generated wave closer to the one that is formed in natural conditions at sea in the area of a gradual rise of the sea or ocean bottom in the coastal zone, while providing the ability to adjust the wave parameters to achieve optimal performance for each specific case (for example, certain wave parameters for athletes of different categories, amateurs, children, adolescents, etc.). The claimed technical result is achieved through the use of a device for the formation of an artificial wave, containing the first and second channels of constant cross-section and a water turbo pump connecting the first and second channels through adapters mating the inlet of the first channel and the outlet of the second channel with the outlet and inlet of the turbo pump, respectively, when the first channel is made with a curved outlet part, and the outlet of the first channel is conjugated with the inlet of the converging nozzle located at a slope in the direction from the outlet of the first channel, the inner space of the nozzle is limited by the upper adjustable plane and the lower plane conjugated at a curved angle with the first edge of the first bottom plane , located with a slope away from the nozzle, the second edge of which is smoothly conjugated with the first edge of the concave bottom surface of the bumper, the second edge of which is hingedly mated with the first edge of the bump stop and goes into the bottom plane at a right angle, then goes down into the niche under the bump stop, into the cat A hydraulic cylinder is located to control the change in the angle of inclination of the bump stop, the second side of the niche under the bump stop is mated with the first side of the second bottom plane, the second edge of which is cut off by a sump, the outlet of which is connected to the inlet of the second channel, while the space of the sump is bounded by a lower flat wall, the lower edge of which is smooth is coupled with the lower edge of the second channel, while the device is made with an open space, limited, on the one hand by the upper plane of the nozzle, on the other hand, by the second edge of the horizontal wall of the sump, and the first, second channels, nozzle, sump, as well as the open space are limited with sides by two vertical walls, made mainly parallel, and the device is equipped with a protective perforated bottom, located at a slope from the sump to the bump stop and attached to the second bottom plane, the vertical wall of the sump, as well as to the vertical walls.

In the particular case of the implementation of the invention, the ridge of the bumper has a rounding with a radius of 1 to 5 mm,

In a particular case of the invention, the converging nozzle is adjusted in the range of width from 100 to 500 mm at the outlet by means of a hydraulic cylinder, and the angle of inclination of the bump stop is adjusted by means of a hydraulic cylinder in the range of inclination of the upper plane relative to the horizon from 5 to 40 degrees. In the particular case of the implementation of the invention, the space of the sump is limited by the upper horizontal wall.

In a particular case of the invention, the upper edge of the lower curved wall of the sump is mated at an angle to the first edge of the upper horizontal wall.

In the particular case of the implementation of the invention, the surface of the walls of the device has a lining, for example, a vinyl film.

In a particular case of the implementation of the invention, the device is made with the possibility of filling with water, the layer of which in a quiet state covers the horizontal surface of the device, while the depth of the water layer is 100-1000 mm.

In the particular case of the implementation of the invention, the device contains from one to fifteen turbopumps, which affects the width of the device.

In a particular case of the implementation of the invention, the adapters for the pumps are made in the form of plates with openings for the inlets and outlets of the pumps.

Due to the fact that water comes out of the converging nozzle into the space of the pool, a turbulent water flow is formed at the outlet of the nozzle, the fluid flow in which is disordered, that is, the trajectories of water particles can arbitrarily intersect and behave quite unpredictably, which is characteristic of sea waves. naturally formed and used for surfing training. Rounding of the baffle surfaces with specified diameters and the possibility of adjusting the bumper tilt angle provide optimal parameters of the standing wave: wave height and liquid depth in front of and after the ridge. The rounding of the top of the reef, made with a radius of no more than 5 mm, ensures effective formation of a turbulent flow behind the reef with the achievement of optimal parameters of the artificial wave along its entire length. In this case, the adjustable surface of the upper part of the pipeline above the outlet nozzle and the adjustable surface of the baffle ensure the regulation of such wave parameters as thickness and height, respectively. The flow rate is regulated by adjusting the pump speed. Adjusting the wave parameters makes it possible to obtain an artificial wave close to the wave obtained in natural conditions, while taking into account the physical capabilities of users (that is, it is possible to customize the wave parameters, for example, for athletes of various categories and experience, amateurs, children, etc.).

CARRYING OUT THE INVENTION

The device for the formation of an artificial wave is a part of the pool and is made of metal or reinforced concrete. The device contains the first 1 and second 2 channels of constant cross-section with a diameter of 500-H 300 mm and a water turbo pump 13, connecting the first and second channels through adapters, mating the inlet of the first channel and the outlet of the second channel with the outlet and inlet of the turbo pump, respectively. The marked positions 1 and 2 indicate the places where pipes are connected to the channels, while the distance between the indicated connection points is at least 3 m.

The first channel 1 is made with a curved outlet part, and the outlet of the first channel is mated with the inlet of the converging nozzle 3, located at a slope away from the outlet of the first channel 1. The inner space of the nozzle 3 is limited by the upper adjustable plane 4 and the lower plane 5. The diameter of the outlet of the nozzle is 100- ^ 500 mm.

The bottom plane 5 of the nozzle 3 is mated at a curved angle with the first edge of the first bottom plane 6, located with a slope away from the nozzle 3. The second edge of the first bottom plane 6 is smoothly conjugated with the first edge of the concave bottom surface 7. The second edge of the concave bottom surface 7 is mated with a hinge 15 with a bumper surface 10. The lower plane of the concave bottom surface 7 mates with the container for installing the hydraulic cylinder 16, the second edge of the container is mated with the first edge of the second bottom plane 9. The second edge of the second bottom plane 9 is cut off by a sump 12, the outlet of which is coupled with the inlet of the second channel 2. The top of the reef (the ridge of the bumper) has a rounding from 1 to 5 mm.

Hydraulic cylinder 16 with a stroke of 50-200 mm N. from. included in the kit of the electric telescopic water-resistant stainless steel drive. It is fastened to the support ledger by means of a threaded connection. The drive is controlled both automatically and manually.

The width of the converging nozzle is adjustable in the range from 100 to 500 mm at the outlet, and the angle of inclination of the baffle is adjusted in the range of inclination of the upper plane 4 relative to the horizontal from 5 to 40 degrees by means of a hydraulic cylinder 17 (telescopic rod) installed above the adjustable surface 4, connected by a hinge 8 to the upper pool surface 18. Hydraulic cylinder 17 with a stroke of 50-300 mm n. from. included in the kit of the electric telescopic water-resistant stainless steel drive. It is fastened to the support ledger by means of a threaded connection. The drive is controlled both automatically and manually.

The space of the sump is limited by the upper horizontal wall and the lower curved wall 12, the lower edge of which is smoothly conjugated with the lower edge of the second channel, and the upper edge, at an angle, is conjugated with the first edge of the upper horizontal wall.

In general, the device is made with an open space, limited on one side by the upper plane of the nozzle, and on the other side by the second edge of the horizontal wall of the sump.

The first and second channels, nozzle, water collector, as well as the open space are bounded from the sides by two vertical walls of the pool, made mainly parallel.

In addition, the device is equipped with a protective perforated bottom 11, located at a slope from the sump to the bump stop and attached to the second bottom plane, the bottom wall of the sump, as well as to the vertical walls. The total area of the holes is from 3.5 to 4.5 m ² . With a total area of the bottom openings less than 3.5 m ^{2, the} rate of water flow into the catchment is significantly reduced, which will disrupt the water recirculation in device for the formation of an artificial wave. When the total area of the bottom holes is more than 4.5 m ^{2, the} mechanical strength of the perforated bottom decreases, which prevents the performance of its protective function.

The pipeline of the flowing part of the device for rigidity is equipped with a frame 20 with rubber damping compensators 19.

The width of the device depends on the number of turbo pumps of the pumps, which can be, mainly, from 1 to 30, but in principle the number of pumps is not limited, respectively, the width of the pool is also not limited, while the width of one section with one turbo pump is 2 m.

The device contains water, a layer of which in a calm state covers the horizontal surface of the device, while the depth of the water layer is 100-300 mm.

Pump adapters are made in the form of plates with holes for pump inlets and outlets.

The device works as follows. The pool is filled with water that enters the collector and the second channel, then a turbo pump is started, pumping water from the second channel into the first channel, mainly in a laminar mode, and from there into a nozzle, from which a water flow breaks out, acquiring a turbulent character with the formation of a wave, which due to the sharp ridge, it takes the form of a standing wave, close to the form of a standing wave formed at sea in the reef area. In this case, in the region of the transition from the first bottom plane to the concave surface of the ridge bumper, the maximum flow velocity is reached, which is extinguished as the flow moves to the top of the wave and reaches a minimum at the top of the wave. The sharp ridge provides a stall and therefore the turbulent flow required to form a high wave. At the top of the standing wave, it is possible for visitors to the amusement park to ride and exercise in maintaining balance, for example, on a surfboard or water skiing. Then the water enters the collector, passes through the second channel, calming down and acquiring a laminar flow, and through the pipeline connecting the first and second channels, it enters the second channel, from where, under the action of the turbo pump, it is pumped into the nozzle, mixing with the air stream and escaping into the first bottom area, repeating the cycle described above. For the proposed device, an axial-type pump is used, since it has a good efficiency at the given parameters (12000 m ³ / h flow rate and up to 4m head), for example, by HEBEI ZIDONG PUMP INDUSTRY CO., LTD, with model 900QGL-100 being preferred. Calculation of different modes of a turbo pump for different wave heights (2m, 1, 4m;

1m):

The flow rate required for a wave height of 2m: Q = up to 12000 m ³ / h; power consumption N = 75KBt.

The flow rate required for a wave height of 1, 4 m: Q = 7700 m ³ / h; power consumption N = 50KBt

For a wave height of 1 m, 0 = 6100 m ³ / h, the power consumption is N = 25KBt.

In addition to the technical aspects required for wave shaping, the device may include ancillary equipment to enable the pool to be entertained, for example the pool may have a built-in bar or stands.
