PUMPEBRØNDPUMP WELL

Den kendte teknik 5 Frembringelsen angår en pumpebrønd til brug ved pumpning af drænvand, spildevand og kloakvand, hvilken brønd er præfabrikeret og fremstillet af kunststof, såsom polyethylen.The prior art provides a pump well for use in pumping drainage, wastewater and sewage, which is prefabricated and made of plastic, such as polyethylene.

Almindelig kendte pumpebrønde til det anførte formål opbyg- 10 ges af beton eller et lignende materiale, idet pumpebrøndene etableres i en udgravning med en passende dybde, hvorefter der på en bundplade stables ringe af beton oven på hinanden, indtil pumpebrøndene har opnået den ønskede dimension i højden. Betonringene aftættes indbyrdes ved hjælp af 15 gummi- eller plasttætninger. Derefter monteres de forskellige elementer, såsom pumpe, elforbindelser, ' pumpestyring m. m. i den således etablerede pumpebrønd, idet der bores monteringshuller for elementerne i betonringene samt gennemgangshuller for rørledninger for tilledning og fraled- 20 ning af mediet, der skal pumpes.Commonly known pump wells for the stated purpose are constructed of concrete or a similar material, the pump wells being established in an excavation of a suitable depth, whereupon rings of concrete are stacked on top of one another until the pump wells have reached the desired dimension. the height. The concrete rings are sealed together by means of 15 rubber or plastic seals. Then the various elements such as pump, electrical connections, pump control etc. are mounted in the pump well thus established, drilling mounting holes for the elements in the concrete rings as well as through holes for piping for feeding and conduction of the medium to be pumped.

For at gøre dette monteringsarbejde både lettere og hurtigere, er det kendt at anvende færdige pumpebrønde.To make this installation work both easier and faster, it is known to use ready-made pump wells.

25 Eksempler på sådanne præfabrikerede pumpebrønde er de i DE offentliggørelsesskrifter hr. 3.430.527 og 4.315.535 kendte pumpebrønde. De er begge fremstillet ved støbning af kunststof med sidevægge og bund støbt ud i et stykke.25 Examples of such prefabricated pump wells are the known wells in DE publication 3,430,527 and 4,315,535. They are both made by molding plastic with side walls and bottom molded in one piece.

30 Disse konstruktioner er imidlertid meget dyre at fremstille, da de er faconstøbte med diverse studse og reduktioner samt ribber og indsnævringer. Dette gør produktet dyrt og endvidere umuligt at tilpasse til andre mål.30 However, these designs are very expensive to manufacture as they are molded with various studs and reductions as well as ribs and narrows. This makes the product expensive and also impossible to adapt to other goals.

35 Den kendte teknik er derfor uhensigtsmæssig i brug, idet arbejdet med at fremstille og montere en pumpebrønd er både 2 DK 96 00281 U4 besværligt og dyrt. Dette gælder uanset om pumpebrønden er fremstillet af betonelementer eller er en præfabrikeret kunststof pumpebrønd.The prior art is therefore inappropriate in use, since the work of producing and installing a pump well is both expensive and expensive. This applies whether the pump well is made of concrete elements or is a prefabricated plastic pump well.

Formålet med frembringelsenPurpose of production

Det er formålet med den foreliggende frembringelse at afhjælpe disse ulemper og mangler ved de kendte pumpebrønde.The object of the present invention is to remedy these disadvantages and shortcomings of the known pump wells.

Den nye teknikThe new technique

Dette formål opnås med en pumpebrønd af den ovennævnte art, hvilken pumpebrønd er ny ved, at pumpebrønden består af et cirkulærtcylindrisk rørstykke med konstant diameter, som i dets ene ende er lukket med en bund i form af en plan cirkulær kunststofplade, som er helsvejset til røret, og som i dets modsatte ende har beslag for montering af et aftageligt dæksel.This object is achieved with a pump well of the above-mentioned type, which pump well is new in that the pump well consists of a circular cylindrical tube of constant diameter, which at one end is closed with a bottom in the form of a flat circular plastic plate which is fully welded to the tube and which has at its opposite end brackets for mounting a removable cover.

Herved opnås på en overraskende enkel måde muligheden for at fremstille en robust pumpebrønd til en hidtil ukendt lav pris p.g.a. de enkelte elementers former og deres sammen-svejselighed.In this way, the possibility of producing a robust pump well at an unprecedentedly low price is achieved in a surprisingly simple way. the shapes of the individual elements and their inter-weldability.

Ved som anført i krav 2 at udforme sidevæggen korrugerende, opnås en god styrke og formfasthed såvel før som efter monteringen.As stated in claim 2, the side wall is corrugated, a good strength and shape strength is obtained both before and after mounting.

Endeligt er det hensigtsmæssigt, som anført i krav 3, at montere alt for pumpebrøndens funktion nødvendige udstyr i pumpebrønden før den installeres, idet monteringsarbejdet derved lettes betydeligt.Finally, as stated in claim 3, it is appropriate to install all the equipment needed for the pump well's function in the pump well before it is installed, thereby considerably facilitating the mounting work.

Beskrivelse af udførelseseksempler På fig. 1 vises et lodret længdesnit i en basisbrønd ifølge frembringelsen. Basisbrønden 1 består af et cirkulærcylindrisk rørstykke, der er fremstillet af plast, for eksempel polyethylen (PEH). Basisbrønden har en efter kapaciteten tilpasset diameter, for eksempel en diameter på 400 mm, 500 mm, 800 mm eller endda større. Basisbrønden 1 er af styrkemæssige årsager udformet med korrugerede sidevægge 2 og har i en første ende en bundplade 3, der er tæt forbundet med sidevæggene 2, ved svejsning. I den åbne anden ende 4 er basisbrønden 1 indrettet til at kunne lukkes med et aftageligt dæksel 5.Description of Embodiments In FIG. 1 shows a vertical longitudinal section in a base well according to the invention. The base well 1 consists of a circular cylindrical tube made of plastic, for example polyethylene (PEH). The base well has a diameter adapted to capacity, for example a diameter of 400 mm, 500 mm, 800 mm or even larger. The base well 1 is designed for strength reasons with corrugated side walls 2 and has at first a bottom plate 3, which is closely connected to the side walls 2, by welding. At the open other end 4, the base well 1 is arranged to be closed with a removable cover 5.

4 DK 96 00281 U4 I åbningen 4 er der til den aftagelige montering af dækslet 5 i indbyrdes ensartet vinkelafstand anbragt beslag 6 til modtagelse af skruer, hvormed dækslet 5 kan fastskrues.4 DK 96 00281 U4 In the opening 4, for the removable mounting of the cover 5, at a uniform angular distance, brackets 6 are arranged for receiving screws with which the cover 5 can be screwed.

Umiddelbart under åbningen 4 findes på den indvendige side et beslag 7 til montering af en tilslutningsdåse for de elektriske forbindelser til drift af pumpen og den hertil hørende pumpestyring, hvilken tilslutningsdåse således befinder sig i sikker afstand over det højest forekommende væskeniveau i pumpebrønden.Immediately below the aperture 4, there is on the inside a bracket 7 for mounting a connection box for the electrical connections for operating the pump and the associated pump control, which connection box is thus located at a safe distance above the highest liquid level in the pump well.

I indbyrdes afstand langs den indvendige side af basisbrønden 1 findes yderligere beslag 9 til fastspænding af en pumpe med et pumperør, idet pumpen er beregnet til montering på almindelig kendt måde nederst i basisbrønden med et pumperør strækkende sig op langs den indvendige sidevæg 2.Further spaced along the inner side of the base well 1 are additional brackets 9 for clamping a pump with a pump tube, the pump being intended for mounting in a generally known manner at the bottom of the base well with a pump tube extending along the inner side wall 2.

Pumperøret er forudset at strække sig tæt under åbningen 4 for at bære et eventuelt måleapparat til bestemmelse af en pumpet vandmængde samt eventuelle ventiler, som er nødvendige til spærring eller åbning af pumperørets forbindelse til et afløb, hvortil der er tilvejebragt en pakdåse 10 i sidevæggen 2 i en nærmere fastsat afløbskote. Pakdåsen 10 er hensigtsmæssigt anbragt diametralt modsat i forhold til beslagene 9 for pumperøret, idet dette giver de korteste rørforbindelser.The pump tube is envisaged to extend close below the aperture 4 to carry any measuring device to determine a pumped amount of water as well as any valves needed to block or open the pump tube connection to a drain for which a sealing box 10 is provided in the side wall 2 in a specified drainage drain. The packing box 10 is suitably arranged diametrically opposite to the brackets 9 of the pump tube, as this provides the shortest pipe connections.

I sidevæggen 2 findes også en tilgangskobling 11, hvortil en tilgang fra en kloak eller en drænledning kan sluttes.In the sidewall 2 there is also an inlet connection 11, to which an approach from a sewer or a drain line can be connected.

De nævnte beslag og tilslutninger er fordelt på sidevæggene 2, hvor det erfaringsmæssigt er fordelagtigt, men kan selvfølgelig også leveres efter nærmere angivne mål ifølge et foreliggende anvendelsessted. Beslagene, pakdåser, skruer og til- og afgangskoblinger er alle udført af rustfaste materialer.Said fittings and connections are distributed on the side walls 2, where it is advantageous in experience, but can of course also be delivered according to specified objectives according to a present application. The fittings, gaskets, screws and connection and exit couplings are all made of stainless steel.

De forskellige beslags fordeling på sidevæggen 2 er fordelagtigt angivet som indbyrdes vinkelafstande, som antydet med vinklen a mellem pakdåsen 10 og tilgangskoblingen 11. Selv om vinkel a er vist som tilnærmelsesvis 90°, er det klart for fagmanden, at vinkel α efter ønske og behov kan have en vilkårlig størrelse.5 DK 96 00281 U4 In FIG. 2, the base well 1 of FIG. 1 from above. Advantageously, the distribution of the various fittings on the side wall 2 is indicated as mutual angular distances, as indicated by the angle α between the packing box 10 and the inlet coupling 11. Although angle α is shown as approximately 90 °, it is clear to those skilled in the art that angle α as desired and required can be of any size.

På fig. 3 vises et dæksel 5 til overdækning af åbningen 4 i basisbrønden 1. Dækslet 5 er forsynet med ikke nærmere viste huller til optagelse af skruer, som ved indgreb med beslagene 6 kan holde dækslet 5 på plads.In FIG. 3, a cover 5 is shown for covering the opening 4 in the base well 1. The cover 5 is provided with holes which are not shown in detail for receiving screws which, by engagement with the fittings 6, can hold the cover 5 in place.

Dækslet 5 kan være en hvælvet dørkplade af aluminium med rustfaste skruer eller være udført af PEH, der er udformet med riller for skridfasthed og ligeledes er fastgjort med rustfaste skruer.The cover 5 may be an aluminum vaulted floor plate with stainless steel screws or may be made of PEH, which is designed with anti-slip grooves and is also secured with stainless steel screws.

På fig. 4 vises en pumpebrønd ifølge frembringelsen med forud fast monteret pumpe med pumpestyring, elanlæg og tilog afgangskoblinger, hvilke sidste under etableringen er sluttet til diverse ledninger. Pumpebrønden 1 er vist nedgravet i jorden og er monteret med de til brugen nødvendige elementer, såsom en pumpe 12, niveaufølere 13, 14 og 15 til henholdsvis alarm for utilsigtet højt væskeniveau, føler for start af pumpen 12 og for stop af pumpen 12. Niveaufølerne 13, 14 og 15 er fordelagtigt almindeligt kendte vippekontakter.In FIG. 4 shows a pump well according to the production of a pre-mounted pump with pump control, electrical system and even discharge connections, the last of which is connected to various wires during the establishment. The pump well 1 is shown buried in the ground and is fitted with the elements needed for use, such as a pump 12, level sensors 13, 14 and 15 respectively for an unintentionally high liquid level sensor, for starting the pump 12 and for stopping the pump 12. The level sensors Advantageously, 13, 14 and 15 are commonly known rocker contacts.

De elektriske forbindelser til pumpen 12 og niveaufølerne 13, 14 og 15 er ført til en tilslutningsdåse, som er fastgjort i beslaget 7.The electrical connections to the pump 12 and the level sensors 13, 14 and 15 are fed to a socket which is secured in the bracket 7.

Pumpen 12 er sluttet til et pumperør 17, der er ophængt i beslagene 9 og fører gennem en måler for den ppmpede væske- DK 96 00281 U4 mængde samt en spærreventil 9 og til et afløbsrør, der er sluttet til pakdåsen 10 for at føres videre til et reservoir.The pump 12 is connected to a pump tube 17 which is suspended in the fittings 9 and passes through a meter for the pumped liquid quantity and a shut-off valve 9 and to a drain pipe connected to the sealing box 10 to be passed to a reservoir.

5 Et ikke vist tilløbsrør er forbundet til tilgangskoblingen 11.5 An inlet pipe not shown is connected to the inlet connection 11.

Pumpebrønden ifølge frembringelsen kan monteres med et bredt udvalg af pumper, alt efter behov og ønsker. Pumpe-10 brønden er til installering, hvor en almindelig gravitationsledning ikke kan anvendes, og nedgraves i passende nærhed af en hovedkloakledning for at undgå for lang en trykledning med stort tryktab til følge. Spildevandsinstallationen sluttes til tilgangskoblingen 11, og afgangsled-15 ningen føres gennem pakdåsen 10.The pump well according to the invention can be mounted with a wide range of pumps, as needed and desired. The pump-10 well is for installation where a normal gravity line cannot be used, and is buried in the appropriate vicinity of a main sewer line to avoid too long a pressure line with a large pressure loss. The wastewater installation is connected to the inlet connection 11 and the discharge line is passed through the sealing box 10.

Spildevandet opsamles i pumpebrønden 1. Når den akkumulerede mængde passer til startkoteniveau, pumpes spildevandet til hovedkloakledningen for afledning til recipient. Ved 20 bortledning af fækalieholdigt spildevand kan det være nødvendigt at føre udluftning fra pumpebrønden over tag.The wastewater is collected in the pump well 1. When the accumulated amount corresponds to the starting cone level, the waste water is pumped to the main sewer pipe for discharge to the recipient. In the case of discharge of fecal-containing wastewater, it may be necessary to vent vent from the pump well over roof.
