Description
Oppfinnelsen vedrører en maskin for fjerning av overflatevann fra eksempelvis sportsplasser og andre rekreasjonsområder. The invention relates to a machine for removing surface water from, for example, sports grounds and other recreational areas.
Utendørs sport har alltid vært utsatt for vær og vind. Vanndammer på en fotballbane eller et cricketfelt, eller Outdoor sports have always been exposed to weather and wind. Water ponds on a football field or a cricket field, or
bare en meget våt overflate på en tennisbane eller en bowling-plen, kan bety at man må kansellere spillet. Det samme gjelder for andre idretts- og sportsbegivenheter, eksempelvis idretts-stevner, hesteveddeløp eller golf. Påtrykk fra spillerne, supportere eller behovet for penger fra betalende tilskuere kan bety at et stevne settes igang på en overflate som er altfor våt. Dette fører ofte til redusert kvalitet av stevnet, med tilhørende skuffede tilskuere, og spillerne kan også derved utsettes for uønskede farer. Det foreligger også en klar fare for at spilleoverflaten skal skades. Nedgravede dreneringssystemer har vært benyttet for å hindre at spilleover-flater blir vasstrukne. Slike dreneringssystemer er dyre i fremstilling og de er ikke effektive med hensyn til rask vannfjerning fra overflaten. Sports- og :'. idretts stevner kan således hindres eller vanskeliggjøres selv et døgn etter at det har falt regn. Meget store og dype vanndammer kan man redusere ved hjelp av vanlige pumpesystemer, men slike pumpesystemer kan ikke fjerne alt overflatevann. just a very wet surface on a tennis court or a bowling green can mean having to cancel the game. The same applies to other sports and sporting events, for example sports events, horse races or golf. Pressure from the players, supporters or the need for money from paying spectators can mean that a match is started on a surface that is far too wet. This often leads to a reduced quality of the event, with associated disappointed spectators, and the players can also thereby be exposed to unwanted dangers. There is also a clear danger that the playing surface will be damaged. Buried drainage systems have been used to prevent playing surfaces from becoming waterlogged. Such drainage systems are expensive to manufacture and they are not effective in terms of rapid water removal from the surface. Sports and :'. sports competitions can thus be prevented or made difficult even a day after it has rained. Very large and deep water ponds can be reduced using normal pumping systems, but such pumping systems cannot remove all surface water.
Det er kjent flere forslag for maskiner som kan absorbereSeveral proposals are known for machines that can absorb
vann fra spilleflater. Slike maskiner skyves forhånden og har en valse som er belagt med absorberende materiale. Materialet tar opp vann fra marken, og dette vannet tømmes water from playing surfaces. Such machines are pushed forward and have a roller that is coated with absorbent material. The material absorbs water from the ground, and this water is drained
så fra materialet og over i en beholder i maskinen. Slike maskiner har ikke vært noen utpreget suksess. Dette skyldes at det er tungt å skyve maskinen over marken, særlig når beholderen er full. Det absorberende materialet kan også skades. then from the material into a container in the machine. Such machines have not been a distinct success. This is because it is difficult to push the machine over the ground, especially when the container is full. The absorbent material can also be damaged.
Med foreliggende oppfinnelse tilveiebringes det en maskinWith the present invention, a machine is provided
for fjerning av overflatevann, hvilken maskin som absorberende materiale benytter et materiale som innbefatter en absorberende for the removal of surface water, which machine as absorbent material uses a material that includes an absorbent
basis og et forsterkende lag på basisens ytterflate, idet det forsterkende lag tillater vann å gå inn og ut av basisen. base and a reinforcing layer on the outer surface of the base, the reinforcing layer allowing water to enter and exit the base.
Et slikt materiale kan tåle de påkjenninger det utsettes for under bruk, selv når maskinen er motordreven. Motordrift av maskinen byr på betydelige.Lfordeler, ikke bare fordi maskinen blir lettere å arbeide med, men også fordi det derved blir mulig å ha en pumpr hvormed vannet kan bringes fra .maskinen til en beholder eller et avløp utenfor spilleflaten. Such a material can withstand the stresses it is exposed to during use, even when the machine is powered. Motor operation of the machine offers significant advantages, not only because the machine is easier to work with, but also because it makes it possible to have a pump with which the water can be brought from the machine to a container or a drain outside the playing surface.
Den absorberende basis innbefatter fortrinnsvis et skummateriale, eksempelvis syntetisk plast eller skumgummi. The absorbent base preferably includes a foam material, for example synthetic plastic or foam rubber.
Det forsterkende lag kan være bundet til basisen ved hjelpThe reinforcing layer can be bonded to the base using
av sveising eller ved hjelp av et adhesiv. Det forsterkende lag kan innbefatte gjennomtrengelig materiale, såsom et med åpen vevnad utført plastmateriale, lignende det som benyttes for skurekluter. by welding or by means of an adhesive. The reinforcing layer can include permeable material, such as an open-weave plastic material, similar to that used for scouring cloths.
Alternativt kan det forsterkende lag være i form av et nettingmateriale som kan være fremstilt av plast eller gummi. Nettingen er fortrinnsvis formstøpt kontinuerlig, slik at filamentene er sammenbundne i krysspunktene. Hvert filament har fortrinnsvis et tverrsnitt med et flatt parti beregnet for kontakt med basisen. Nettets rutenett kan eksempelvis ligge i området 4-5 cm, og filamentbredden kan være ca. 2 mm. Alternatively, the reinforcing layer can be in the form of a mesh material which can be made of plastic or rubber. The mesh is preferably molded continuously, so that the filaments are bound together at the crossing points. Each filament preferably has a cross-section with a flat portion intended for contact with the base. The grid of the net can, for example, be in the range of 4-5 cm, and the filament width can be approx. 2 mm.
Selv om maskinen ifølge foreliggende oppfinnelse først og fremst er utviklet for fjerning av overflatevann fra rekreasjonsområder, såsom sportsplasser, cricketfelt og lignende, kan den eksempelvis også benyttes for fjerning av andre væsker enn vann, eksempelvis fra fabrikkområder. Although the machine according to the present invention is primarily developed for the removal of surface water from recreational areas, such as sports fields, cricket fields and the like, it can also be used, for example, for the removal of liquids other than water, for example from factory areas.
Oppfinnelsen.skal forklares nærmere under henvisning til tegningene, hvor: Fig. 1:1 viser.i.et: .sidériss' .av: en maskin som egnenseg for fjerning av overflatevann fra sportsplasser, fig. 2 viser et skjematisk perspektivriss av det væske- absorberende element i maskinen i fig. 1, The invention shall be explained in more detail with reference to the drawings, where: Fig. 1:1 shows a side view of a machine suitable for removing surface water from sports fields, fig. 2 shows a schematic perspective view of the liquid absorbent element in the machine in fig. 1,
fig. 3 viser et grunnriss av det væske-absorberende elementfig. 3 shows a plan view of the liquid-absorbing element
i fig. 3, ogin fig. 3, and
fig. 4 viser tre alternative tverrsnittsformer for det forsterkende lag i fig. 2 og 3. fig. 4 shows three alternative cross-sectional shapes for the reinforcing layer in fig. 2 and 3.
Maskinen i fig. 1 har en ramme 2 hvori det er opplagret en valse„4. Valsen 4 drives av en motor 6. En valse 8 med mindre diameter er anordnet for å gi maskinen stabilitet, The machine in fig. 1 has a frame 2 in which a roller 4 is stored. The roller 4 is driven by a motor 6. A roller 8 with a smaller diameter is arranged to give the machine stability,
og maskinen har et håndtak 10 slik at den kan styres av en operatør som går bak maskinen. Egnede styreorganer (ikke vist) er montert på håndtaket 10. and the machine has a handle 10 so that it can be controlled by an operator walking behind the machine. Suitable control means (not shown) are mounted on the handle 10.
Valsen 4 er belagt med et væske-absorberende element 12.The roller 4 is coated with a liquid-absorbing element 12.
Som det går frem av fig. 1 presses dette elementet 12As can be seen from fig. 1 this element is pressed 12
mellom valsen 4 og marken under påvirkning av maskinens vekt. Elementet sammenpresses også av en klemvalse 14 between the roller 4 and the ground under the influence of the machine's weight. The element is also compressed by a pinch roller 14
som er anordnet bak valsen 4.which is arranged behind the roller 4.
Ved bruk av maskinen vil motoren 6 dreie valsen 4, hvorved maskinen drives over det området som skal klargjøres. Når elementet 12 ruller over marken blir det progressivt trykket sammen ved markkontakten, med etterfølgende ekspandering. When using the machine, the motor 6 will turn the roller 4, whereby the machine is driven over the area to be prepared. When the element 12 rolls over the ground, it is progressively compressed at the ground contact, with subsequent expansion.
Når elementet 12 beveger seg fra marken og tillates å eks-pandere vil det trekke vann i fra markflaten. Dette vannet tas med av elementet 12 opp til klemvalsen 14 som bevirker en fornyet komprimering av elementet 12, hvorved vann klemmes ut og over i et ikke vist trau i bunnen av rammen 2. Derfra pumpes vannet ved hjelp av en ikke vist pumpe, som drives av motoren 6, over i en beholder i maskinen, eller til en nærliggende beholder, gjennom en tilknyttet slange. When the element 12 moves from the ground and is allowed to expand, it will draw water in from the ground surface. This water is taken by the element 12 up to the pinch roller 14 which causes a renewed compression of the element 12, whereby water is squeezed out and over into a trough not shown at the bottom of the frame 2. From there the water is pumped with the help of a pump not shown, which is driven of the motor 6, into a container in the machine, or to a nearby container, through a connected hose.
Fig. 2 viser skjematisk en utførelse av det materiale som det væske-absorberende element 12 er bygget opp av. Elementet 12 innbefatter en absorberende basis 15 forsynt med et forsterkende lag 16. Den absorberende basis 15 består av et ettergiv ende syntetisk plastmateriale eller skumgummi, og det forsterkende lag består av et støpt plastmateriale i form av en nett-ing som er bundet til basisen 15 ved sveising eller ved hjelp av et egnet adhesiv. Fig. 2 schematically shows an embodiment of the material from which the liquid-absorbing element 12 is built. The element 12 includes an absorbent base 15 provided with a reinforcing layer 16. The absorbent base 15 consists of a flexible synthetic plastic material or foam rubber, and the reinforcing layer consists of a molded plastic material in the form of a net which is bonded to the base 15 by welding or using a suitable adhesive.
Tykkelsen av basisen 15 er ca. 4 cm. Som vist i fig. 3 er rutestørrelsen i nettingen fortrinnsvis 4 til 5 cm, selv om man for noen formål, eksempelvis for innendørs bruk, kan be-nytte rutenett i størrelsen 1 cm. Fig. 4 viser tre mulige tverrsnittsutførélser for nettingfilamentet, her et triangu-lært tverrsnitt A, et kvadratisk tverrsnitt B og et i hoved-saken kvadratisk tverrsnitt med avrundet ytterkontur C. The thickness of the base 15 is approx. 4 cm. As shown in fig. 3, the grid size in the netting is preferably 4 to 5 cm, although for some purposes, for example for indoor use, grids of the size 1 cm can be used. Fig. 4 shows three possible cross-sectional designs for the mesh filament, here a triangular cross-section A, a square cross-section B and a mainly square cross-section with a rounded outer contour C.
I hvert tilfelle innbefatter tverrsnittet en plan flate 18In each case, the cross-section includes a flat surface 18
som sikrer god kontakt mellom nettingen 16 og basisen 15. Filamentene danner ribber som rager ut i fra basisen 15. which ensures good contact between the mesh 16 and the base 15. The filaments form ribs that protrude from the base 15.
I hvert tilfelle er filamentbredden og- høyden ca. 2 mm. In each case, the filament width and height are approx. 2 mm.
Istedenfor det viste forsterkende lag 16 kan det benyttes andre materialtyper. Eksempelvis kan det benyttes et med åpen vevnad utført plastmateriale, og hvis så tilfelle bør tykkelsen av det forsterkende lag være i området 1% mm til 5 mm. Materialet blir fortrinnsvi sveiset eller bundet til basisen 15 over hele området, men på en måte som ikke med-fører en barriere som kan hindre overgangen av vann mellom det forsterkende lag og basisen. Instead of the reinforcing layer 16 shown, other types of material can be used. For example, an open-weave plastic material can be used, and if this is the case, the thickness of the reinforcing layer should be in the range of 1% mm to 5 mm. The material is preferably welded or bonded to the base 15 over the entire area, but in a way that does not create a barrier that can prevent the passage of water between the reinforcing layer and the base.
Det forsterkende lag 16 gir øket motstand mot skader på den relativt ømtålige basis 15, eksempelvis som følge av stener eller andre skarpe gjenstander som ligger på marken, og hindrer at riss forplanterseg i basisen 15. Motstanden mot nedsliting som følge av gnidning blir også bedre. Man har dessuten funnet at det relativt stive forsterkende lag 16 gjør det mulig for det væske-absorberende element 12 å "•fcerenge dypere inn i en myk overflate, eksempelvis en gress-plen eller et belegg, slik at derved vannopptagningen fra slike flater øker. The reinforcing layer 16 provides increased resistance to damage to the relatively fragile base 15, for example as a result of stones or other sharp objects lying on the ground, and prevents cracks from propagating in the base 15. The resistance to wear and tear as a result of rubbing is also improved. It has also been found that the relatively stiff reinforcing layer 16 makes it possible for the liquid-absorbing element 12 to penetrate deeper into a soft surface, for example a grass lawn or a covering, so that water absorption from such surfaces increases.
Selv om oppfinnelsen foran er beskrevet med særlig referanse til en motordreven maskin for klargjøring av relativt store områder, såsom sportsplasser, så kan naturligvis maskiner ifølge oppfinnelsen også benyttes for absorbering av andre væsker enn vann, eksempelvis i fabrikker og andre industri-områder, under forutsetning av at basisen 15 og det forsterkende lag 16 velges slik at de er kompatible med de.væsker som skal absorberes. Although the invention is described above with particular reference to a motor-driven machine for preparing relatively large areas, such as sports fields, machines according to the invention can of course also be used for absorbing liquids other than water, for example in factories and other industrial areas, provided of the base 15 and the reinforcing layer 16 being chosen so that they are compatible with the liquids to be absorbed.
