Description

Područje tehnike na koje se izum odnosi Technical field to which the invention relates

Ovaj izum odnosi se na proizvodnju električne energije iz prirodnih izvora slatke vode ispod površine, odnosno s dna mora - vrulje. This invention relates to the production of electricity from natural sources of fresh water below the surface, that is, from the bottom of the sea - Vrulje.

Tehnički problem Technical problem

U današnje je vrijeme naročito istaknuta potreba za pronalaskom, novih, obnovljivih ekonomsko i ekološki isplativih izvora energije, u ovom slučaju električne energije iz podmorskih izvora. Nowadays, the need to find new, renewable, economically and ecologically profitable sources of energy, in this case electricity from undersea sources, is especially prominent.

Izlaganje biti izuma Presentation of the essence of the invention

Vrulje su do sada malo ili nikako iskorišteni prirodni fenomen. Pogodno konstruiranim sustavom usmjerivača toka vode koji pokreće turbinu, moguća je proizvodnja električne energije iz povremenih, a naročito stalnih izvora vode pod morem. Zbog jeftinoće sklopa, jednostavne ugradnje, i bez devastacije okoliša, ova elektrana se nameće kao rješenje problema dobivanja jeftine energije. U prilog proizvodnje ovakvog sustava govori podatak da su sustavi diskretni i malih dimenzija. Usporedba: stotinjak mogućih montiranih elektrana na vrulje, procijenjene snage 200 MW po površini zauzimanja morskog prostora zauzima znatno manju površinu od jedne prosječne nautičke marine. Hot springs are a natural phenomenon that has not been used much or at all until now. With a suitably designed system of water flow diverter that drives the turbine, it is possible to produce electricity from intermittent, and especially permanent sources of water under the sea. Due to the cheapness of the assembly, simple installation, and without devastation of the environment, this power plant is imposed as a solution to the problem of obtaining cheap energy. In support of the production of such a system, the fact that the systems are discrete and of small dimensions speaks. Comparison: about a hundred possible installed hot water power plants, with an estimated power of 200 MW per area occupying sea space, occupy a significantly smaller area than an average nautical marina.

Kratki opis crteža Brief description of the drawing

Crtež na SL.1 prikazuje presjek elektrane na vrulje s osnovnim sastavnim dijelovima koji su dovoljni za proizvodnju električne energije. Kućište cilindričnog oblika 1, načinjeno od metala ili staklo-plastike, usmjerava mlaz vrulje na turbinu 2. Promjer i visinu kućišta 1 određuje kapacitet i brzina protoka pojedine vrulje. Turbina 2 kratkom osovinom vezana je na generator električne struje 3, koji je akva-dinamičkog dizajna i efikasno hlađen vodom koja prolazi uz njega. Turbina 2 i generator 3 učvršćeni su tankim i čvrstim držačem 4. Kućište 1 je uzdignuto od dna mora 5 i oslanja se na nogare 6, usidre u temelje 11. Zbog stabilnosti i čvrstoće uređaja preporuča se da temelj 6 bude u obliku armirano-betonskog prstena. Razmak na slici označen s h je nužan da omogući upliv morske vode 7 koja zbog gustoće veće od slatke vode vrulje 8 stvara dodatni uzgon i brzinu mlaza vode vrulje 8. Prema saznanjima hidrodinamike upliv morske vode povećava brzinu i do tri puta. Dobivena električna energija iz generatora 3 podvodnim kablom 9 provodi se do najbližeg distribucionog električnog voda na kopnu. Kućište 1 zaštićeno je čvrstom metalnom mrežom 10 iz sigurnosnih razloga. The drawing in FIG. 1 shows a section of a thermal power plant with basic components that are sufficient for the production of electricity. Cylindrical housing 1, made of metal or glass-plastic, directs the stream of hot water to turbine 2. The diameter and height of housing 1 determines the capacity and flow rate of each hot water. Turbine 2 is connected by a short shaft to the electric current generator 3, which has an aqua-dynamic design and is efficiently cooled by the water passing by it. The turbine 2 and the generator 3 are fixed with a thin and strong holder 4. The housing 1 is raised from the bottom of the sea 5 and rests on legs 6, anchored in the foundations 11. Due to the stability and strength of the device, it is recommended that the foundation 6 be in the form of a reinforced concrete ring . The gap in the picture marked with h is necessary to enable the inflow of seawater 7, which, due to its density greater than fresh hot water 8, creates additional buoyancy and the speed of the jet of hot water 8. According to the knowledge of hydrodynamics, the inflow of seawater increases the speed up to three times. The obtained electrical energy from the generator 3 is carried by underwater cable 9 to the nearest distribution power line on land. The housing 1 is protected by a solid metal mesh 10 for safety reasons.

Detaljan opis ostvarivanja izuma Detailed description of the realization of the invention

Uz rješavanje administrativnog dijela problema nužno je provesti i istraživanja za dobivanje osnovnih parametara: dubine na kojoj se vrulja 8 nalazi, površine izvora iste, te brzine njenog mlaza. In addition to solving the administrative part of the problem, it is necessary to carry out research to obtain the basic parameters: the depth at which the hot spring 8 is located, the surface of its source, and the speed of its jet.

Prema dobivenim rezultatima procjenjuje se vrijednost moguće količine električne energije (MW) koja određuje dimenzije kućišta 1, visinu, promjer, zakrivljenost 12 unutrašnjosti i udaljenost od podloge 5. Ta zakrivljenost 12 povećava brzinu mlaza vrulje 8. Taj mlaz svojim protokom pokreće turbinu 2 na osovini generatora 3. Električna energija prenosi se električnim kabelom 9 do spojnog mjesta na kopnu. Predlaže se da turbina 2 bude izvedena temelju dizajna Aldenove turbine koja uz maksimalnu iskoristivost na manjim protocima vode ima i karakteristiku da ne ozljeđuje (fish-friendly) veće i manje morske organizme što je čini izuzetno ekološki prihvatljivom. Potrebno je cijeli sustav zaštititi zaštitnom mrežom 10, zbog sprečavanja oštećenja upadom brodskih sidara ili kamenja s obale. According to the obtained results, the value of the possible amount of electricity (MW) is estimated, which determines the dimensions of the housing 1, height, diameter, curvature 12 of the interior and distance from the base 5. This curvature 12 increases the speed of the hot jet 8. This jet, with its flow, drives the turbine 2 on the shaft generator 3. Electric energy is transmitted by electric cable 9 to the connection point on land. It is proposed that turbine 2 be built based on the design of Alden's turbine, which, in addition to maximum utilization at smaller water flows, also has the characteristic of not harming (fish-friendly) larger and smaller marine organisms, which makes it extremely environmentally friendly. It is necessary to protect the entire system with a protective net 10, in order to prevent damage from the intrusion of ship anchors or stones from the shore.

Način primjene izuma Method of application of the invention

Elektrana na vrulje postavlja se na odabrana mjesta (vrulje 8) radi dobivanja električne energije potrebne za napajanje domaćinstva i industrije. Zbog relativno male težine sustava, potpuno sastavljena elektrana spušta se nad vrulju 8. Hot water power plants are installed in selected locations (hot water 8) in order to obtain the electricity needed to power households and industry. Due to the relatively low weight of the system, the fully assembled power plant descends over the hot 8.
