Abstract

The present invention relates to a grating cleaning device (1), which comprises a grating (2) and a motor-driven cleaning instrument (3), which cooperates with the grating by means of a rake-like cleaning instrument. According to the invention the portions of the cleaning instrument and the grating, which can mesh with each other, have a multi-fonctional design and purpose, i.e. to, in an introduction period, when they are mutually jointed together, carry out an alignment into the fully joined and consequently final work position, and by means of the alignment design, already in said introduction period carry out a coarse cleaning and achieve an increase in the capacity of the grating to retain contaminants with reduced risk of obstructing the flow, which passes through the grating and, in the final work position, also to accomplish a fine cleaning.

Similar problems and inconveniences exist with the articles of US-A-2 009 005 and US-A-1 912 020.

Genom US-A-4 138 334 är tidigare känd en uppsamlingsanordning för vätskeburna föroreningar enligt ingressen till patentkravet 1, var- vid ovannämnda olägenheter består.U.S. Pat. No. 4,138,334 discloses a collection device for liquid-borne contaminants according to the preamble of claim 1, in which the above-mentioned disadvantages persist.

Syftet med föreliggande uppfinning är att motverka och så långt som möjligt eliminera ovannämnda problem och brister. Dessutom åligger det uppfinningen att rent allmänt vidareutveckla teknikens stånd- punkt på detta område.The object of the present invention is to counteract and as far as possible eliminate the above-mentioned problems and shortcomings. In addition, it is the responsibility of the invention to further develop the state of the art in this field in general.

Dessa syftemål förverkligas enligt uppfinningen genom att en gal- lerrensningsanordning av det inledningsvis beskrivna slaget i hu- vudsak är så beskaffad, som anges i den kännetecknande delen av pa- tentkravet l.These objects are realized according to the invention in that a grid cleaning device of the type described in the introduction is essentially as described in the characterizing part of claim 1.

Ytterligare kännetecken av och fördelar med uppfinningen framgår av följande beskrivning under hänvisning till bifogade ritningar, som föreställer ett föredraget, dock ej begränsat utföringsexempel av en gallerrensningsanordning enligt uppfinningen. I detalj förestäl- ler i delvis schematiserad form: Fig l en tvärsektion av en gallerrensningsanordning enligt uppfinningen enligt sektionslinjen I - I i fig 2, Fig 2 en sidovy av anordningen enligt fig 1 och härtill relaterade delar, Fig 3 en vy från vänster i fig 2 av det motordrivna rengöringsredskapet, Fig 4 en sektionsvy av ett galler enligt uppfinningen enligt sektionslinjen IV - IV i fig 1, Fig 5 en vy från vänster i fig 1 samt Fig 6 - 9 tvärsektioner av alternativa gallerutföranden.Further features and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawings, which show a preferred, but not limited, embodiment of a grid cleaning device according to the invention. In detail represents in partially schematic form: Fig. 1 a cross section of a grid cleaning device according to the invention according to section line I - I in Fig. 2, Fig. 2 a side view of the device according to Fig. 1 and related parts, Fig. 3 a view from the left in fig. Fig. 2 of the motor-driven cleaning tool, Fig. 4 a sectional view of a grid according to the invention according to section line IV - IV in Fig. 1, Fig. 5 a view from the left in Fig. 1 and Figs. 6-9 cross-sections of alternative grid designs.

I ritningsfigurerna betecknas med 1 en gallerrensningsanordning i dess helhet. I denna ingår som huvuddelar ett galler 2 och ett mo- 10 15 20 25 30 #35 40 511 044 tordrivet rengöringsredskap 3.In the drawing figures, 1 denotes a grid cleaning device in its entirety. This includes, as main parts, a grille 2 and a motor-driven cleaning tool 3 15 15 25 25 # 35 40 511 044.

Anordningen är främst avsedd för galler i relativt djupa och smala schakt eller kanaler 4, där gallret 2 kan anordnas exempelvis vi- lande på en botten 5 och utfyllande mellanrummet mellan sidoväggar 6, varvid gallret lämpligen ges ett lutande läge enligt fig 2.The device is primarily intended for grids in relatively deep and narrow shafts or channels 4, where the grid 2 can be arranged, for example, resting on a bottom 5 and filling the space between side walls 6, the grid being suitably given an inclined position according to Fig. 2.

Ett galler 2 enligt uppfinningen består av en ram 7 med eller utgö- rande runtomgående sidoprofiler, mellan vilka sträcker sig inbördes parallellt gallerstavar 8 och 9 av företrädesvis plattjärn, vilka hos anordningen lämpligen är belägna inom lodräta plan, vilka är parallella med ett genom gallret passerande vattenflöde.A grid 2 according to the invention consists of a frame 7 with or constituting circumferential side profiles, between which grid bars 8 and 9 of preferably flat iron extend mutually parallel, which of the device are suitably located within vertical planes, which are parallel to a passage passing through the grid. water flow.

Gallerstavarna bildar med den ena av sina långkanter mot flödes- riktningen åtminstone två från varandra i flödesriktningen distan- serade plan 10 och ll, t ex genom att plattjärnen 8 och 9 är olika breda i flödesriktning och är anordnade växelvis enligt fig 1. Al- ternativt kan plattjärnen vara lika breda i flödesriktning, men sluta inom olika plan på den nedströms belägna sidan (fig 7). En- ligt ytterligare ett alternativ kan det finns grupper om tre, eller ännu fler, med hänsyn till bredden i flödesriktningen varierande plattjärn 8, 9 och 9' (fig 6b).The grid bars form with one of their long edges towards the flow direction at least two planes 10 and 11 spaced apart from each other in the flow direction, for example in that the flat irons 8 and 9 are different widths in the flow direction and are arranged alternately according to Fig. 1. For example, the flat irons can be equally wide in the direction of flow, but end within different planes on the downstream side (Fig. 7). According to a further alternative, there may be groups of three, or even more, with regard to the width in the flow direction varying flat irons 8, 9 and 9 '(Fig. 6b).

Gallret uppvisar nedtill en mot flödesriktningen sluttande sida 12 och på sidorna mot flödesriktningen divergerande instyrningssidor 13, vars baser 14 lämpligen är inbördes parallella och skjuter fram något längre i riktning mot flödet än de bredaste (alternativt de i gallrets tvärsektion längst mot flödet framskjutna) stavarna. Di- vergensen av sidorna 13 svarar vid de fria långkanterna mot mellan en och två delningar mellan nämnda bredaste eller längst framskjut- na stavar, medan sidornas 13 utsträckning i flödesriktning är 1 - 5 ggr gallrets utsträckning i samma led.The grid has at the bottom a side 12 sloping towards the flow direction and on the sides towards the flow direction diverging guide sides 13, the bases 14 of which are suitably mutually parallel and project slightly further in the direction of the flow than the widest (alternatively those in the grid cross section opposite the flow) rods. The divergence of the sides 13 corresponds at the free long edges to between one and two divisions between said widest or farthest projecting rods, while the extent of the sides 13 in the direction of flow is 1-5 times the extent of the grid in the same direction.

Avståndet mellan bredvid varandra belägna stavar uppgår till 2 - 60 mm, i praktiska, oftare förekommande utföringsexempel 10 - 20 mm.The distance between adjacent rods amounts to 2 - 60 mm, in practical, more frequent embodiments 10 - 20 mm.

Rengöringsredskapet 3 uppvisar ett i riktning mot och från gallret 2 medelst en elmotor 15 svängbart skaft 16. Ett stativ 17 till el- motorn 15 kan vara lagrat på en med löprullar 18 försedd vagn 19, vilken i sin tur är förflyttbar utmed löpbanor 20, 21, vilka exem- 10 15 20 25 30 35 40 511 044 4 pelvis är fastsatta vid ett golvstöd 22, som kan sänkas ned på kantområdet kring nämnda schakt e dyl 4. Motorn driver lämpligen både nämnda löprullar och en svängningsanordning 23 till skaftet 16, så att detta tillsammans med ett vid dess fria, dvs nedre ände anordnat rengöringsorgan 24 kan svängas mot och från gallret, var- vid deras lutningar relativt gallret förändras. I fig 2 visas ren- göringsorganets nedkörningsläge, där skaftet är svängt bort från gallret. När det nedre utgångsläget har nåtts, svänges skaftet mot- sols, tills rengöringsorganet med sin fria, från skaftet vända kant slår emot gallret. Slutskedet i denna fas visas i fig 1. Där ser man, att det ungefärligen som en tvärgående skovel utformade rengö- ringsorganet 24 uppvisar en vid skaftet fäst basplatta 25, från vilken utgår i en vinkel på cza 120° nedåt en bladdel 26, till vil- ken i sin tur ansluter en krattdel 27 intagande en vinkel på cza 90° relativt skaftet 16. Såsom framgår av fig 1, är krattdelens 27 fria långkant utförd med relativt breda, trapetsformiga tänder 28, vars bas 29 är lika bred som avståndet mellan två närbelägna gal- lerstavar 9 i det yttre planet 10, och vars topp 30 är smalare än nämnda avstånd. Toppen upptar centralt en relativt flack rektangu- lär skåra 31, vars vidd är aningen större än tjockleken av galler- stavarna 8. Alternativt till trapetsformiga tänder 28 kan det fin- nas rektangulära sådana. Återgående till ovannämnda slutfas ser man, att rengöringsorganet 24 enkelt och automatiskt centreras närmast av nämnda instyrnings- sidor 13 och sedan av deras baser 14, så att luckorna 32 mellan tänderna 28 befinner sig exakt mittför stavarna 9 och skårorna se- dan hamnar mittför stavarna 8 medförande, att en skrapningsrörelse kan äga rum dubbel i två olika plan i gallrets djupled. Skulle ste- nar, grenar och/eller andra föroreningar hindra rengöringsorganet 24 från att fullt tränga in i gallret på det ovan beskrivna sättet utan tillåta ett inträngande till exempelvis det i fig 1 visade lä- get, så kan en meningsfull skrapnings- och rengöringsrörelse ändå utföras med ett avlägsnande av sådana grövre hinder i en första om- gång, varefter finare föroreningar avlägsnas i en andra omgång, om nu inte rengöringsorganet under den uppåtgående skrapningens gång kan intränga djupare i gallret. Bortskrapade föroreningar hamnar på delarna 25 - 27 och forslas uppåt genom att motorn drar hela rengö- ringsredskapet uppåt till ett läge ovanför marknivån, där tömning sker. 10 15 20 25 30 35 40 511 044 5 Även gallrets utformning i sig är mycket fördelaktig, eftersom de olika, mot flödet vända planen försvårar eller förhindrar igensätt- ning av gallret, då ev hinder tvingas inta sneda lägen relativt gallret, varigenom ett visst fortsatt flöde garanteras trots ev större mängder ansamlade föroreningar. Givetvis är tack vare den visade och beskrivna utformningen även ett avlägsnande av både gro- va och fina föroreningar och naturligtvis ett alltid garanterat korrekt instyrningsläge säkerställda. Instyrningssidorna svarar dessutom för en fördelaktig tvärströmning från sidorna, vilken försvårar en enhetlig igensättning med föroreningar.The cleaning tool 3 has a shaft 16 which can be pivoted in the direction of and from the grid 2 by means of an electric motor 15. A stand 17 for the electric motor 15 can be mounted on a trolley 19 provided with running rollers 18, which in turn is movable along running tracks 20, 21. , which are for instance fixed to a floor support 22, which can be lowered to the edge area around said shaft etc. 4. The motor suitably drives both said rollers and a pivoting device 23 to the shaft 16, so that this together with a cleaning means 24 arranged at its free, i.e. lower end can be pivoted towards and away from the grid, whereby their slopes relative to the grid change. Fig. 2 shows the lowering position of the cleaning means, where the shaft is pivoted away from the grille. When the lower starting position has been reached, the shaft is swung counterclockwise until the cleaning member with its free edge facing away from the shaft strikes the grille. The final stage in this phase is shown in Fig. 1. It can be seen that the cleaning member 24 designed approximately as a transverse vane has a base plate 25 attached to the shaft, from which a blade part 26 extends at an angle of about 120 ° downwards, to which in turn, a scrub part 27 connects at an angle of about 90 ° relative to the shaft 16. As shown in Fig. 1, the free long edge of the scrub part 27 is made with relatively wide, trapezoidal teeth 28, the base 29 of which is as wide as the distance between two adjacent grid bars 9 in the outer plane 10, and the top 30 of which is narrower than said distance. The top centrally occupies a relatively flat rectangular notch 31, the width of which is slightly greater than the thickness of the grid bars 8. Alternatively, trapezoidal teeth 28 may have rectangular ones. Returning to the above-mentioned final phase, it is seen that the cleaning means 24 is simply and automatically centered closest to said guide sides 13 and then by their bases 14, so that the gaps 32 between the teeth 28 are exactly opposite the rods 9 and the grooves then end up opposite the rods 8. entailing that a scraping movement can take place double in two different planes in the depth of the grid. Should stones, branches and / or other contaminants prevent the cleaning means 24 from fully penetrating the grid in the manner described above without allowing an intrusion into, for example, the position shown in Fig. 1, a meaningful scraping and cleaning movement can still is carried out with a removal of such coarser obstacles in a first round, after which finer contaminants are removed in a second round, unless the cleaning means during the course of the upward scraping can penetrate deeper into the grid. Scraped-off contaminants end up on parts 25 - 27 and are transported upwards by the engine pulling the entire cleaning tool upwards to a position above ground level, where emptying takes place. 10 15 20 25 30 35 40 511 044 5 The design of the grid itself is also very advantageous, since the different planes facing the flow make it difficult or prevent clogging of the grid, as possible obstacles are forced to assume oblique positions relative to the grid, whereby a certain continuation flow is guaranteed despite any large amounts of accumulated contaminants. Of course, thanks to the design shown and described, the removal of both coarse and fine contaminants and, of course, an always guaranteed correct control position are always ensured. The guide sides also account for an advantageous transverse flow from the sides, which complicates a uniform clogging of contaminants.

Uppfinningen är inte begränsad till ovan beskrivna och på bifogade ritningar visade utföranden utan kan modifieras och kompletteras på godtyckligt sätt inom ramen för uppfinningstanken och följande pa- tentkrav.The invention is not limited to the embodiments described above and shown in the accompanying drawings, but can be modified and supplemented in any way within the scope of the inventive concept and the following patent claims.
