Description

The utility model relates to the field of training devices for surfing, as well as to the field of entertainment, more specifically relates to devices for the formation of artificial waves.

A "Wave Generator" is known from the prior art according to patent No. US5098222 dated 02.10.1989 for an invention (IPC E04H 4/00; F04D 35/00). A wave generator comprising: an inlet/outlet for water located in a pool of water, wherein said inlet/outlet is located above the water level of said pool; a chamber in fluid communication with said water inlet/outlet through communication means below the water level in the pool, wherein said chamber extends upward to a level substantially above the water level in the pool of water; means extending through said inlet/outlet to ensure water flow past said inlet/outlet in the direction of said chamber; valve means connected to said chamber and controlled with the possibility of controllably moving between an open position, exiting the chamber into the atmosphere, and a closed position, preventing air flow from passing through it; an air pump connected to said chamber for removing air from it; wherein water can be drawn from the pool into said chamber by removing air from it by means of said air pump means and quickly pushed out of it through said inlet/outlet opening for generating a wave by opening said valve means for ventilating said chamber. A disadvantage of this invention is the presence of an inlet/outlet opening for water located in the water pool above the water level of said pool; this design is unsafe for the athlete and does not allow the use of waves directly at the outlet of the wave generator. Also, this invention does not allow the use of the energy of the reverse wave, which significantly increases the filling time of the wave generator. In the claimed solution, the wave generator does not have parts protruding above the water and allows the use of a wave in the immediate vicinity of the wave generator chamber, and also has a system of valves that allow the use of the energy of the reverse wave during operation of the wave generator.

The task set by the developer of the new vacuum wave generator was to create a new device that is free of the disadvantages of known solutions. The technical result consists in increasing the efficiency of the generator, reducing the time for producing waves, while increasing safety during use. The technical result also consists in ensuring the possibility of using the energy of the reverse wave.

Fig. 8 – schematically shows a vacuum wave generator in operation – using the energy of the reverse wave.

The essence of the utility model is that the vacuum wave generator consists of a chamber with an inlet/outlet for water at the bottom and a vacuum pump connected to at least one chamber, wherein at least one valve is designed in the upper part of the chamber, connected to the pneumatic cylinder and installed with the possibility of forming a gap at the point of connection with the chamber, wherein the valve is made with the possibility of creating excess air pressure in the chamber upon arrival of a reverse wave to ensure the release of air from the chamber, preventing the reverse flow of air, the vacuum pump is connected to the chamber connected to the air manifold through a check valve, and the inlet/outlet for water is designed below the water level. In addition, the chamber is at least one hollow container for filling with water. And the valve is a gate valve or a plate valve.

The vacuum wave generator consists of a chamber 1 with an inlet/outlet opening 2 for water at the bottom and a valve 3 at the top, as well as a vacuum pump 4 connected to at least one chamber 1 via an air manifold 5 connected to a check valve 6 for removing air from the chamber 1. The chamber 1 is at least one hollow container for filling with water. The chamber 1 is designed to draw water from the reservoir through the inlet/outlet opening 2 and then release the water into the reservoir to form an artificial wave. The inlet/outlet opening 2 is located below the water level. When the inlet/outlet opening is located above the water level of the pool, the use of the vacuum wave generator is unsafe for the athlete and does not allow the use of waves directly at the outlet of the wave generator. The location of the inlet/outlet opening below the water level allows the use of waves directly near the vacuum wave generator. In the upper part, chamber 1 is connected to vacuum pump 4, through air manifold 5 and check valve 6. Air manifold 5 is necessary when using several generators with one vacuum pump, it allows to pump air evenly from several chambers. On the upper surface of chamber 1 there is at least one valve 3, connecting the internal cavity of chamber 1 with the atmosphere. Valve 3 is fixed on chamber 1 with the possibility of forming a gap, as shown in Fig. 3. Valves 3 open and close on command of the operator. Valve 3 is intended for forming a vacuum in the upper part of chamber 1 during operation of vacuum pump 4. Valve 3 closes the opening in chamber 1 from above. Water is sucked in by means of vacuum, then when valve 3 is opened by means of pneumatic cylinders 7, air enters chamber 1 and the entire volume of water falls down, thereby creating a wave. The valve 3 closes immediately after the water falls in the chamber 1. After which the valves 3 perform the function of plate valves when a reverse wave arrives in the chamber 1, excess air pressure is created in the chamber 1, the valves 3 rise upward, releasing it, but do not allow the air to return to the chamber 1, thereby maintaining the amount of water in the chamber 1, significantly reducing the time for further filling of the chamber 1. When using several chambers 1 located next to each other, the opening of the valves 3 is regulated by a computer program that opens the valves 3 simultaneously or in turn, which allows creating waves with different directions. With a sequential discharge of water, the wave in the pool can have a direction, in this case, the chamber 1 is connected to the collector 5 through the check valve 6, which prevents the vacuum in the chamber 1 from falling when the vacuum in the collector 5 falls, for example, when opening the adjacent chambers 1 or when the vacuum pump 4 is turned off. The air pump 4 can be any of the various types of pumps. Gate valve 3 is a gate valve or a plate valve. Gate valve 3 is located on the upper surface of chamber 1. In a specific example of implementation (Fig. 2), eight gate valves 3 and four pneumatic cylinders 7 are installed on chamber 1. Gate valve 3 is designed to form a vacuum in the upper part of chamber 1 when air pump 4 is operating.

The vacuum wave generator works as follows. To generate a wave, close valve 3 of the vacuum wave generator and turn on vacuum pump 4. Then remove air from chamber 1, creating a vacuum. Water is sucked into chamber 1 by means of the vacuum. Then valve 3 is opened, air enters chamber 1 and the entire volume of water falls down through inlet/outlet opening 2, thereby creating a wave next to chamber 1. The wave, moving in the direction from chamber 1, rests against the bottom with its lower part and rises up, thereby creating the necessary wave height. The shape of the wave directly depends on the shape of the bottom: the sharper it becomes shallow, the higher the wave becomes. Under natural conditions, at great depth, the mass of water moves uniformly, but when the wave reaches shallow water, it slows down, its length shortens, and the crest grows, that is, the wave becomes higher.
