TEKNIKKENS STANDPUNKTBACKGROUND OF THE ART

Frembringelsen angår et apparat forsynet med en roterbar rensebørste og til rengøring af bassinvægge.The production relates to an apparatus provided with a rotatable cleaning brush and for cleaning pool walls.

Apparater forsynet med en roterbar rensebørste, til rengøring af bassinvægge er kendt teknik i forbindelse med renseanlæg opbygget med enten cirkulære eller rektangulære tanke, hvor disse apparater findes fast monterede på gang-10 broer til hvilke der er tilknyttet skraberarragement for rengøring af tankbunden. Rensebørstearrangementet fremføres således i samme takt som gangbroen/skraberen bevæges. Ren-sebørsterne anvendes til at fjerne de urenheder, hidrørende fra spildevandet, der måtte have sat sig fast på bassinvæg-15 gene som følge af varierende vandstandsniveau i bassinerne. Det er imidlertid ikke alle renseanlæg der har et sådant rensebørstearrangement, især på renseanlæg af ældre dato findes rensebørster ikke, og her udføres rengøring af tilgængelige bassinkanter manuelt. Endvidere findes der ikke 20 børstearrangementer til rengøring af de i tankene værende skillevægge, hvorfor det hidtil har været nødvendigt at rengøre disse manuelt. Dette rengøringsarbejde er forbundet med arbejdsmiljømæssige faremomenter, som følge af at adkomsten til skillevæggene er betinget af at personen der 25 skal udføre rengøringen af bassinernes skillevægge, er nødsaget til at bevæge sig på dennes kant, hvilket under normale driftsituation for et renseanlæg er forbudt i medfør af arbejdsmiljøloven. Eneste mulighed for manuel rengøring har således været at det pågældende bassin tages ud af 30 drift, bassinet tømmes for sit indhold, hvorefter manuel rensning kan udføres. Denne ressourcekrævende indsats, har medført at rengøring af bassinsider på utilgængelige steder kun gennemføres sjældent eller slet ikke. Ved manuel rengøring af umiddelbart tilgængelige bassinsider er der risiko 35 for at personen der udfører rengøringen indånder de aerosoler samt gasser af forskellig art spildevandet afgiver, i 2 DK 93 00359 U3 forbindelse med rensning i et traditionelt renseanlæg. Personen der udfører dette arbejde må derfor iføres maske eller andet åndedrætsbeskyttelses-udstyr.Apparatus provided with a rotatable cleaning brush for pool wall cleaning is known in the art for cleaning systems constructed with either circular or rectangular tanks, where these appliances are fixedly mounted on walkways to which scraping arrangement is attached for cleaning the tank floor. Thus, the cleaning brush arrangement is advanced at the same rate as the walkway / scraper is moved. The cleaning brushes are used to remove the impurities from the wastewater that may have become trapped on the basin walls due to varying water levels in the basins. However, not all wastewater treatment plants have such a cleaning brush arrangement, especially at older wastewater treatment plants, there are no cleaning brushes, and cleaning of available pool edges is done manually here. Furthermore, there are no 20 brush arrangements for cleaning the partitions in the tanks, so it has so far been necessary to clean them manually. This cleaning work is associated with occupational hazards due to the fact that access to the partitions is conditional on the person having to do the cleaning of the partitions of the basins is forced to move on its edge, which is prohibited under normal operating situation for a treatment plant. of the Work Environment Act. The only possibility for manual cleaning has thus been that the basin in question is taken out of operation, the basin is emptied of its contents, after which manual cleaning can be performed. This resource-intensive effort has resulted in cleaning of basin sites in inaccessible places only rarely or not at all. By manual cleaning of immediately accessible basin sides, there is a risk that the person performing the cleaning inhales the aerosols as well as gases of various kinds of waste water, in connection with treatment in a traditional wastewater treatment plant. Therefore, the person performing this work must wear a mask or other respiratory protective equipment.

Det har således hidtil været et meget ressourcekrævende arbejde at renholde bassinkanter og skillevægge i bassiner på renseanlæg, grundet ovenfor beskrevne sikkerhedsmæssige aspekter vedrørende dette arbejdes udførelse manuelt, hvorfor dette vigtige arbejde kun sjældent eller slet ikke udføres.So far, it has been a very resource-intensive job to clean basin edges and partitions in basins at wastewater treatment plants, due to the safety aspects described above regarding the execution of this work manually, so this important work is rarely or not performed at all.

FORKLARING AF FREMBRINGELSENEXPLANATION OF PRODUCTION

Apparatet ifølge frembringelsen nyt ved, at apparatet består af en vogn af en basisramme med fremdriftsmiddel og anbragt kørbart på et hjulsæt, hvilken basisramme er forsynet med en drivanordning, der er forbundet med en nedadra-gende roterbar aksel, på hvilken aksels modsatte ende ren-sebørsten er fastgjort og på hvilken basisramme findes fastgjorte nedadragende holdeorganer som er forsynet med løberuller på de mod bassinvæggene vendende sider for styring af vognen på bassinkanten.The apparatus according to the invention is new in that the apparatus consists of a trolley of a basic frame with propulsion means and positionably mounted on a wheel set, which base frame is provided with a drive device connected to a downwardly rotatable shaft, on which the opposite end of the shaft is cleaned. the sieve brush is fixed and on which base frame are mounted downwardly holding retaining means which are provided with running rollers on the sides facing the pool walls for controlling the carriage on the pool edge.

Apparatets virkemåde er at dette placeres på bassinkanten, således orienteret at rensebørsten orienteres mod den bassinvæg der skal rengøres. Apparatet sættes herefter i drift, hvorved dette bevæger sig i den ønskede retning på bassinkanten, samtidigt med at rensebørsten roterer og derved rengør bassinsiden for urenheder. Apparatets fremdriftsretning styres af operatøren via et styrekabel. Apparatet fastholdes på bassinkanten af de nedadragende holdeorganer.The operation of the apparatus is that this is placed on the basin edge, so that the cleaning brush is oriented towards the basin wall to be cleaned. The apparatus is then put into operation, whereby it moves in the desired direction on the pool edge, at the same time as the cleaning brush rotates, thereby cleaning the pool side for impurities. The operating direction of the device is controlled by the operator via a control cable. The apparatus is held on the basin edge by the downwardly holding means.

Grundet ovenfor beskrevne udformning og virkemåde af apparatet kan rengøring af såvel tilgængelige som vanskeligt tilgængelige bassinsider på eksempelvis renseanlæg udføres på en mere hensigtsmæssig måde set i relation til arbejds-Due to the design and operation of the apparatus described above, cleaning of both accessible and difficult-to-reach basin sides on, for example, purification plants can be carried out in a more convenient manner in relation to working conditions.

Ved at udføre apparatet som omtalt i krav 4, opnås den fordel at apparatet bliver lettere at anbringe på bassinkan-5 ten, idet basisrammen med hjul kan adskilles fra børsten med drivanordning, således kan dette arbejde kan udføres i to tempi, hvorved den byrde der skal løftes ad gangen bliver mindre.By designing the apparatus as claimed in claim 4, the advantage is obtained that the apparatus becomes easier to place on the pool edge 5, since the base frame with wheels can be separated from the brush with a driving device, thus this work can be carried out in two temps, thereby reducing the burden therein. must be lifted at a time becomes smaller.

10 Ved at udføre apparatet som omtalt i krav 5, opnås der mulighed for at udskifte rensebørsten uden også at skulle udskifte akselen.By operating the apparatus as claimed in claim 5, it is possible to replace the cleaning brush without also having to replace the shaft.

Ved at udføre apparatet som omtalt i krav 6 og 7, åbnes der 15 mulighed for at kunne operere med apparatet på bassinkanter med forskellig bredde, hvilket medfører at apparatet kan benyttes på flere forskellige renseanlæg.By designing the apparatus as claimed in claims 6 and 7, 15 opens the possibility of operating with the apparatus on different width pool basins, which means that the apparatus can be used on several different treatment plants.

Ved at udføre apparatet som omtalt i krav 8 og 9 opnås der 20 mulighed for tilførsel af spule- og skyllevand under rengøringsprocessen .By designing the apparatus as claimed in claims 8 and 9, 20 provides the possibility of supply of rinsing and rinsing water during the cleaning process.
