Description
och 1 m, vanligtvis 0,5 m, är den horisontella filtmattsdelen 12 av den hindrande bommen tillräckligt lång för att samla in exempelvis de blågröna alger som kommer in med bränningarna till stränderna i sjöar. Höjden på den vertikala delen 1 av bommen kan vara i storleksanordningen 1,2 till 3,0 m, vanligtvis mellan 1,4 och 2,5 m. and 1 m, usually 0.5 m, the horizontal felt mat part 12 of the obstructing boom is long enough to collect, for example, the blue-green algae that enter with the surf to the shores of lakes. The height of the vertical part 1 of the boom can be in the size device 1.2 to 3.0 m, usually between 1.4 and 2.5 m.
Filtmattan 1 är företrädesvis en geotextil som används vid markarbete såsom ett filtmaterial. Detta filtmaterial är vanligtvis en filtmatta gjord av tunna polypropylen- eller polyesterflber och har en tjocklek på mellan 0,5 och 2 mm som är lätt vattengenomsläpplig men så tät att även väldigt små partiklar fastnar på den. Denna typ av icke-vävda filtmatta kan tillverkas med hjälp av nålning eller fibrerna kan läggas i lager medelst blåsning. Förstärkande lager som är vävda kan användas om det visar sig nödvändigt. Tester har visat att blågröna alger fastnar i filtmattan utan att passera igenom den. Den specifika vikten hos filtmattans 1, 12 materialet är något lägre än den hos vatten och därmed tenderar den horisontella mattdelen 12 att ställa sig rakt upp. Mellan flötena 4 och 4a kan emellertid styva avståndshållare placeras som håller dem på avstånd från varandra.The felt mat 1 is preferably a geotextile used in earthworks as a felt material. This felt material is usually a felt mat made of thin polypropylene or polyester fibers and has a thickness of between 0.5 and 2 mm which is easily water-permeable but so dense that even very small particles stick to it. This type of non-woven felt mat can be made by needling or the fibers can be layered by blowing. Reinforced layers that are woven can be used if it proves necessary. Tests have shown that blue-green algae get stuck in the felt mat without passing through it. The specific gravity of the material of the felt mat 1, 12 is slightly lower than that of water and thus the horizontal mat part 12 tends to stand straight up. Between the floats 4 and 4a, however, rigid spacers can be placed which keep them at a distance from each other.
De blågröna alger som samlas in kan avlägsnas från filtmattan med hjälp av exempelvis en högtrycksspruta och på så sätt göra mattan klar för återanvändning.The blue-green algae that are collected can be removed from the felt mat with the help of, for example, a high-pressure sprayer and in this way make the mat ready for reuse.
En typisk filtmatta har en slät yta och en luddig yta som används som den främre insamlingsytan när mattan dras framåt. l en föredragen utföringsform av uppfinningen är kanterna på filtmattan 1 ihoprullade till kanaler 2 och 3 i vilka flytanord ningen 4a och tyngden 5 är placerade.A typical felt mat has a smooth surface and a fuzzy surface that is used as the front collection surface when the mat is pulled forward. In a preferred embodiment of the invention, the edges of the felt mat 1 are rolled up into channels 2 and 3 in which the floating device 4a and the weight 5 are placed.
En jämn icke-vävd filtmatta kan fixeras runt flötena 4 och 4a och vikten 5 med exempelvis de C-formade fjädrarna som visas i figur 2 vilka kan vara tillverkade av plaströr genom att man sågar en slits på längden 14 i röret och skär det i bitar av önskad storlek. Längden på de C-formade fjädrarna 13 kan vara 30-50 mm, ø 25-30 mm och de kan fästas exempelvis två per meter. Alternativt eller dessutom kan man använda spännband, liknande de kabelband som elektriker använder.A smooth nonwoven felt mat can be fixed around the floats 4 and 4a and the weight 5 with, for example, the C-shaped springs shown in Figure 2 which can be made of plastic tubes by sawing a slot of length 14 in the tube and cutting it into pieces of desired size. The length of the C-shaped springs 13 can be 30-50 mm, ø 25-30 mm and they can be attached for example two per meter. Alternatively or in addition, you can use straps, similar to the cable ties that electricians use.
Flötena 4, 4a är exempelvis ett poröst plaströr eller stång och vikten 5 kan vara en metallkätting. Som vikter kan man också använda separata ankarvikter 11 placerade på ett avstånd från varandra.The floats 4, 4a are, for example, a porous plastic tube or rod and the weight 5 may be a metal chain. As weights, one can also use separate anchor weights 11 placed at a distance from each other.
Flötena 4 och 4a kan också bestå enbart av filtmaterial som är ihoprullat.The floats 4 and 4a can also consist only of felt material which is rolled up.
Filtematerialet fungerar då som en flytanordning som är lättare än vatten och som en bra draglina tack vare sin styrka. Rullen av upprullat filtmaterial 1, 12 kan spännas fast med hjälp av en C-formad fjäder som i figur 2.The felt material then functions as a floating device that is lighter than water and as a good towline due to its strength. The roll of wound felt material 1, 12 can be clamped by means of a C-shaped spring as in figure 2.
Den hindrande bommen som formas av filtmattan 1, 12, vilken är L-formad itvärsnitt, kan bestå av element av önskad längd, exempelvis 10-20 m, vilka är sammanfogade vid ändarna som förlängningar av varandra. För att åstadkomma denna sammanfogning så kan ändarna på filtmattan göras överlappande och kanalerna 2 och 3 kan sammanfogas med exempelvis med spännband som träs genom hål gjorda i filtarna 1, 12. Andra sammanfogningsanordningar såsom bindningsanordningar vid elementens ändar kan också användas.The obstructing boom formed by the felt mat 1, 12, which is L-shaped in cross section, may consist of elements of the desired length, for example 10-20 m, which are joined at the ends as extensions of each other. To achieve this joining, the ends of the felt mat can be made overlapping and the channels 2 and 3 can be joined together with, for example, straps which are threaded through holes made in the felts 1, 12. Other joining devices such as binding devices at the ends of the elements can also be used.
LM fnul E20 RJ lLD Ûííl För sammanfogning kan exempelvis rep 6 placerade inuti ihåliga flöten 4 användas vid vars ändar det finns öglor som kan användas iförlängningsskarvarna. Repet 6 tar upp dragspänningen när bommen sträcks mellan de olika ankaranordningarna eller när bommen 1, 12 dras för att samla in blågröna alger.LM fnul E20 RJ lLD Ûííl For joining, for example, rope 6 placed inside hollow floats 4 can be used at the ends of which there are loops that can be used for the extension joints. The rope 6 absorbs the tensile stress when the boom is stretched between the various anchor devices or when the boom 1, 12 is pulled to collect blue-green algae.
Figur 3 visar en uppsamlingsfarkost, såsom en pontonflotte 7, ovanpå vilken det finns en relativt stor perforerad behållare 10 invändigt klädd med filtermaterial vilket företrädesvis liknar det material som beskrivs ovan i samband med den hindrande bommen 1, 12. Den långa uppsamlingsbommen 1, 12 som är fastsatt vid ena ändan av farkosten 7 dras av en bogserbåt eller båt 8 så att bommen formar en ögla som minskar i storlek i närheten av farkosten 7. Den blågröna algslammet som samlats inuti öglan pumpas med hjälp av en flytande slampump 9 inuti behållaren 10 från vilken vatten töms ut genom filtmaterialet och hålen medan de blågröna algerna stannari behållaren 10.Figure 3 shows a collecting vessel, such as a pontoon raft 7, on top of which there is a relatively large perforated container 10 lined internally with filter material which preferably resembles the material described above in connection with the obstructing boom 1, 12. The long collecting boom 1, 12 which is attached to one end of the vessel 7 is pulled by a tugboat or boat 8 so that the boom forms a loop which decreases in size in the vicinity of the vessel 7. The blue-green algal sludge collected inside the loop is pumped by means of a liquid sludge pump 9 inside the container 10 from which water is discharged through the fuel material and the holes while the blue-green algae remain in the container 10.
Filtmattan som används för att hindra blågröna alger behöver inte nå så djupt eftersom problemet med blågröna alger förekommer under varma perioder när de blågröna algerna stiger och lägger sig nära ytan. När man drar långa filtmattor kan det vara fördelaktigt att använda ett nät som påminner om ett dragnät som stödkonstruktion. Stödnätet kan placeras bakom filtmattan.The felt mat used to prevent blue-green algae does not have to reach as deep as the problem with blue-green algae occurs during hot periods when the blue-green algae rise and settle near the surface. When pulling long felt mats, it can be advantageous to use a net that resembles a pull net as a support construction. The support net can be placed behind the carpet.
