Abstract
Prinsippet framgår av figur 1, hvor en bølge kommer inn fra venstre mot flottøren (10) som løftes opp og bølgen går videre inni kanalen (1). Via vektstangen (9), som er opplagret i (13), tvinges spjeldet (3) ned og stenger kanalen (1). Figurene 1 og 5 viser posisjonen ved stengt kanal. Det oppstår et støt som bevirker en trykkøkning i bølgen, slik at tilbakeslagsventilen (5) åpnes og vann strømmer gjennom åpningen (6) inn i beholderen (2). Når trykket avtar i kanalen vil ventilen (5) stenge åpningen (6). Vektarmen (9) går ned slik at spjeldet (3) åpner kanalen igjen. Dette gjentas for hver store bølge som kommer. Et annet alternativ til spjeldets åpningsmekanisme er vist på figur 6. Her tenkes at spjeldet åpnes og stenges vha av en hydraulisk sylinder (13). Aktivatoren (5) kan også være styrt av en hydraulisk sylinder. Samkjøringen av (15) og (5) kan da programmeres og styres f eks vha bølgeregistrator. Når trykket er stort nok i beholderen (12) åpnes magnetventilen (11) og vannet går til en turbin for strømproduksjon, eventuelt at vannet går til et reservoar.The principle is shown in figure 1, where a wave enters from the left towards the float (10) which is lifted up and the wave proceeds inside the channel (1). Via the lever (9), which is stored in (13), the damper (3) is forced down and closes the channel (1). Figures 1 and 5 show the closed channel position. A shock results in a pressure increase in the wave, so that the check valve (5) opens and water flows through the opening (6) into the container (2). When the pressure decreases in the duct, the valve (5) will close the opening (6). The weight arm (9) goes down so that the damper (3) opens the channel again. This is repeated for every major wave that comes. Another alternative to the damper opening mechanism is shown in Figure 6. Here, the damper is thought to be opened and closed by a hydraulic cylinder (13). The actuator (5) may also be controlled by a hydraulic cylinder. The interconnection of (15) and (5) can then be programmed and controlled, for example, by means of a wave register. When the pressure is large enough in the container (12), the solenoid valve (11) opens and the water goes to a turbine for power production, possibly the water goes to a reservoir.
Description
Bakgrunn Background
Omforming av bølgeenergi, til f eks elektrisk energi, er en miljøvennlig prosess som kommer under begrepet fornybar energi. Ved konverteringen er det ikke noe utslipp av miljøskadelige stoffer som C02(g). Å komme fram til gode løsninger er meget viktig og det er uttrykt en omfattende interesse for konvertering av bølgekraft. Litteraturen beskriver et stort antall forslag på bølgekraftverk, men per i dag er det få løsninger som kan betraktes som økonomisk lønnsomme. Foreliggende oppfinnelse vedrører en anordning for å omforme bølgeenergi til mekanisk eller elektrisk energi er angitt i patentkrav 1. Oppfinnelsen videreutvikler prinsippet for en støthevert, som er oppfunnet i 1796 av franskmannen Joseph Michel Montgolier. Foreliggende oppfinnelse dreier seg om et system som regulerer en støthevert som konverterer bølgeenergi til trykkener gi. Transforming wave energy, for example into electrical energy, is an environmentally friendly process that comes under the term renewable energy. During the conversion, there is no emission of environmentally harmful substances such as C02(g). Arriving at good solutions is very important and extensive interest in the conversion of wave power has been expressed. The literature describes a large number of proposals for wave power plants, but as of today there are few solutions that can be considered economically profitable. The present invention relates to a device for transforming wave energy into mechanical or electrical energy is stated in patent claim 1. The invention further develops the principle of a shock sieve, which was invented in 1796 by the Frenchman Joseph Michel Montgolier. The present invention relates to a system that regulates an impact sieve that converts wave energy into pressure energy.
Detaljert beskrivelse av oppfinnelsen Detailed description of the invention
Prinsippet framgår av etterfølgende figurer, figur 1 illustrerer at vann fra en bølge kommer inn kanalen (1) og går inn i en beholder (2) ved hjelp av reguleringsenheter. Når en bølge kommer inn fra venstre inn i kanalen (1) løftes flottøren (10) opp samtidig som utløpet av kanalen (1) stenges av et spjeld (3). Flottøren (10) er monter til en vektstang (9) i den ene ende og et spjeld i den andre enden av vekstangen som er opplagret i (13), dvs. når flottøren (10) går opp tvinges spjeldet (3) ned og stenger kanalen (1). Spjeldet (3) går ned i en styrespalten (14). Se figur 1 og figur 5 som viser posisjonen ved stengt kanal. Slissen (11) lages for unngå at vektstangen kiler seg fast. Når spjeldet (3) er nede oppstår et støt som bevirker en trykkøkning i bølgen, ventilen (5) åpnes og vann strømmer gjennom åpningen (6) inn i beholderen (2). Når trykket avtar i kanalen vil ventilen (5) stenge åpningen (6). Vannet i beholderen (2) går ut gjennom et rør (4) til en turbin eller et høyereliggende reservoar. Røret (4) er tilknyttet en tilbakeslagventil som forhindrer vannretur gjennom røret (4) inn i beholderen (2). Vektarmen (9) går slik at spjeldet (3) åpner kanalen igjen og ventilen (5) lukkes. Dette gjentas for hver store bølge som kommer. Mekanismen for å åpne og stenge ventilen (5) er en aksling (7) som er forbundet med ventilen (5) i den ene ende og en veiv (8) i den andre. Akslingen (7) går gjennom veggen på beholderen (2), hvor en pakkboks tetter rundt akslingen (7). Veiven (8) er tilknyttet en slisse på vektarmen (9). Et annet alternativ til spjeldets åpningsmekanisme er vist på figur 6. Her tenkes at spjeldet åpnes og stenges vha av en hydraulisk sylinder (13). En trykkmåler (15) kan benyttes for å styre den hydraulisk sylinder som også kan programmeres og styres f eks vha en bølgeregistrator. Den hydraulisk sylinder kan også være til hjelp for å redusere tiden for å stenge og åpne henholdsvis spjeld (3) og ventil (5). The principle can be seen from subsequent figures, figure 1 illustrates that water from a wave enters the channel (1) and enters a container (2) with the help of regulation units. When a wave enters the channel (1) from the left, the float (10) is lifted up at the same time as the outlet of the channel (1) is closed by a damper (3). The float (10) is fitted to a weight bar (9) at one end and a damper at the other end of the riser which is stored in (13), i.e. when the float (10) goes up, the damper (3) is forced down and closes the channel (1). The damper (3) goes down into a guide slot (14). See Figure 1 and Figure 5 which show the position when the channel is closed. The slot (11) is made to prevent the barbell from getting stuck. When the damper (3) is down, a shock occurs which causes a pressure increase in the wave, the valve (5) is opened and water flows through the opening (6) into the container (2). When the pressure decreases in the channel, the valve (5) will close the opening (6). The water in the container (2) goes out through a pipe (4) to a turbine or a higher reservoir. The pipe (4) is connected to a non-return valve which prevents water from returning through the pipe (4) into the container (2). The weight arm (9) moves so that the damper (3) opens the channel again and the valve (5) closes. This is repeated for each large wave that comes. The mechanism for opening and closing the valve (5) is a shaft (7) which is connected to the valve (5) at one end and a crank (8) at the other. The shaft (7) passes through the wall of the container (2), where a packing box seals around the shaft (7). The crank (8) is connected to a slot on the weight arm (9). Another alternative to the damper's opening mechanism is shown in Figure 6. Here, it is thought that the damper is opened and closed by means of a hydraulic cylinder (13). A pressure gauge (15) can be used to control the hydraulic cylinder, which can also be programmed and controlled, for example, using a wave recorder. The hydraulic cylinder can also help to reduce the time to close and open respectively damper (3) and valve (5).
