Definitions
- the present invention relates to wave generating machines and in particular to a wave generating machine that can be employed to provide a variety of wave profiles within pools of either regular or irregular shaped perimeters.
- Wave generating machines have grown in popularity in recent years becoming a common feature in many sport and leisure pools. Traditionally such devices are incorporated at one end of a regular shaped pool whereby fan driven air ducts and valve systems are employed to generate the waves in a single directional mode. Alternatively mechanical means are employed to generate the waves in such regular shaped pools. These mechanical means are driven in physical contact with the surface water so as to produce waves substantially along the length of the pool.
- the floating ball offers it's own inherent disadvantages. In the first instance it can only generate circular waves that expand from the floating ball. Therefore, the amplitude of the waves generated in any particular direction is the same and so the floating ball is unable to take account of the actual dimensions of the pool.
- a second disadvantage of the floating ball technique is the fact that an electrical cable is required to be run from the ball to the side of the pool. If the cable is allowed to remain free to run across the bottom of the pool it can result in certain discomforts or safety compromises with regards the combination of electricity and water. In this situation pool users could also become entangled with the cable. Alternatively if the cable runs underneath the pool it could be damaged on the edge of the pool leading to obvious safety and access problems. Running the cable underneath the pool also restricts the flexibility of positioning of the floating ball.
- a wave generating machine for a pool wherein the wave generating machine is provided within a fixed structure, and wherein the fixed structure is located independently from the perimeter of the pool.
- the wave generating machine comprises two or more wave chambers, wherein at least two of the wave chambers are located so as not to be substantially parallel to each other.
- the wave generating machine further comprises a wave control chamber and a valve system located at the interface of the wave control chamber and each wave chamber, wherein each wave chamber generates waves of variable amplitude and frequency.
- the wave control chamber comprises an access means, a control means, at least one fan, at least one air compressor, and air ducts.
- the wave chambers further comprise an access restricting means located at the outer perimeter of the wave generating machine.
- the i.ccess restricting means comprises a grille.
- the amplitude of the generated waves is controlled by the dimensions of the wave chambers and the air pressure supplied to the wave chambers via the air ducts by the air compressor and fan.
- the frequency of the generated waves is controlled by the timing of the valve system.
- the wave profile generated by the wave generating machine depends on the relative timing of the valve systems of each wave chamber.
- valve system comprises an air supply valve an exhaust valve and a splash guard.
- control means is an on site computer system.
- control means is a remote computer system.
- each air compressor, fan and valve system are controlled by the computer.
- the external surface of the fixed structure is in the form of an island comprising artificial landscape and vegetation.
- the air from the exhaust means is directed to produce an artificial air movement across the island.
- a method of generating waves comprising the steps: 1. Drawing air into a wave control chamber; 2. Controllably passing air from the wave control chamber into two or more wave chambers. 3. Pressurising air in a wave chamber to a predetermined value. 4. Opening an exhaust valve to expel air from a wave chamber.
- the passing of air from the wave control chamber into a wave chamber is achieved by the opening of an inlet valve.
- the opening and closing of the inlet and exhaust valves is controlled by an automated timing means.
- the amplitude, frequency and direction of the generated waves is controlled by the timing means in combination with the air pressure associated with each wave chamber.
- Figure 1 shows a plan view of a wave generating machine
- Figure 2 shows the wave generating machine of Figure 1 generating substantially radial waves
- Figure 3 shows the wave generating machine of Figure 1 generating substantially tangential waves
- Figure 4 shows the wave generating machine of Figure 1 generating waves within an irregular shaped pool
- Figure 5 shows a side profile of the wave generating machine of Figure 1
- a wave generating machine is generally depicted at 1.
- the wave generating machine 1 is situated below water level and comprises a wave control chamber 2, and eight wave chambers 3 located around the perimeter of the wave control chamber 2.
- the wave control chamber 2 further comprises an access staircase 4, a control panel 5, two fans 6, an air compressor 7, and two air ducts 8.
- valve system 9 is pneumatically controlled via the air compressor 7 and comprises an air supply valve 10 connected to an air duct 8, an exhaust valve 11, and a splash guard 12.
- air supply valve 10 connected to an air duct 8, an exhaust valve 11, and a splash guard 12.
- safety grilles 13 On the outer perimeter of the wave chambers 3 are located safety grilles 13.
- the splash guards 12 are designed to prevent water passing from the wave chambers 3 into the wave control chamber 2.
- the wave chamber perimeter safety grilles 13 are designed to prevent bathers gaining entry to the wave chambers 3.
- the wave generating machine 1 operates on the principle that air is drawn from the surroundings via air intakes (not shown) into the wave control chamber 2. It is then passed via the fans 6 into the air ducts 8 and thereafter passes through the air supply valve 10 and into the wave chambers 3 where the pressurised air creates a wave, before being passed back into the wave control chamber 2 via the exhaust valves 11.
- the amplitude and frequency of a wave created by an individual wave chamber 3 is controlled by the fans 6 and the timing of the pneumatically controlled air supply valves 10 and exhaust valves 11.
- the air compressor 7, fans 6 and valve timings are controlled on site by the control panel 5 or at the poolside via a remote control panel 14.
- the control panels 5 or 14 employ Programmable Logic Controllers (PLC) that allow programming of the airflow into each individual wave chambers 3.
- PLC Programmable Logic Controllers
- Figure 2 shows an embodiment of the wave generating machine 1 wherein it is employed to generate radial waves within a circular pool 15.
- the individual wave chambers 3 are employed to produce waves of the same amplitude and frequency.
- Figure 3 shows an embodiment of the wave generating machine 1 wherein it is employed to generate tangential waves within a circular pool 15.
- the individual wave chambers 3 are again employed to produce waves of the same amplitude and frequency.
- Figure 4 shows a further embodiment of the wave generating machine 1 wherein it is employed to generate substantially radial waves within an irregular shaped pool 16.
- the individual wave chambers 3 are employed to produce waves of an amplitude and frequency dictated by the dimension of the perimeter of the pool.
- the wave generating machine 1 In order to enhance the physical appearance of the wave generating machine 1 it is housed within a fabricated island 17 as shown in Figure 5.
- the fabricated island comprises a rock or landscape 18 on which are mounted vegetation 19 in the form of plants and trees.
- exhaust air from the exhaust valves 11 is routed so as to simulate a breeze effect on the vegetation 19.
- the present invention has the advantage that it enables waves of varying amplitudes and frequencies to be generated within predetermined sectors so as to provide the creation of efficient wave patterns within pools of regular or irregular shape.
