Lækagesikringssystem og slangevinder til vandforsyningsinstallationerLeak protection system and hose reel for water supply installations
Det tekniske områdeThe technical area
Den foreliggende opfindelse angår lækagesikring af vandforsyningsinstallationer.The present invention relates to leakage protection of water supply installations.
Baggrund for opfindelsen bygningsreglement 2018 §121 fremgår det, at formålet med at installere slangevinder er at sikre, at personer i bygningen kan foretage en indledende indsats. Der skal bl.a. installeres slangevinder i følgende bygninger/bygningsafsnit: - Bygningsafsnit i anvendelseskategori 1, der er indrettet til industri- og lagerbygninger samt avls- og driftsbygninger til dyrehold, hvis etagearealet er større end 1.000 m?. - Bygningsafsnit i anvendelseskategori 2 og 3, der er indrettet til mere end 150 personer, herunder også garageanlæg. + Alle bygningsafsnit i anvendelseskategori 5 og 6. Ved benyttelse af lækagesikring i bygninger hvor der også er installeret slangevinder, skal det sikres, at der vil være vandforsyning til slangevinderne, i tilfælde af en opstået brand.Background to the invention Building Regulations 2018 §121 states that the purpose of installing a hose reel is to ensure that people in the building can make an initial effort. There must, among other things, hose winder is installed in the following buildings/building sections: - Building sections in use category 1, which are designed for industrial and storage buildings as well as breeding and operational buildings for animal husbandry, if the floor area is greater than 1,000 m?. - Sections of buildings in use categories 2 and 3 that are designed for more than 150 people, including garage facilities. + All building sections in application categories 5 and 6. When using leakage protection in buildings where hose reels are also installed, it must be ensured that there will be a water supply to the hose reels in the event of a fire.
En slangevinder er som udgangspunkt udført med formfast slange udført i overensstemmelse med DS/EN 694, og er oprullet på en drejelig, fastmonteret evt. svingbar vinde, som er udført i overensstemmelse med kravene i DS/EN 671-1. Vand indføres i centret af vinden enten direkte eller over en fødeslange, der er i fast forbindelse med bygningens vandforsyning via afspærringsventil før slangevinden. En slangevinde kan være indbygget i et skab. Slangen skal være vandfyldt, men er ikke under tryk. Der er en afspærringsventil umiddelbart ved vandtilførslen til selve slangevinden, der som skal åbnes før brug. Der er i nogle slangevindere anvendt en automatventil, hvilke betyder, at når slangen bliver trukket et par meter ud, så åbnes derA hose reel is basically made with shape-retaining hose made in accordance with DS/EN 694, and is wound on a rotatable, permanently mounted possibly swingable winch, which is made in accordance with the requirements of DS/EN 671-1. Water is introduced into the center of the wind either directly or via a feed hose that is in fixed connection with the building's water supply via a shut-off valve before the hose wind. A hose reel can be built into a cabinet. The hose must be full of water, but not under pressure. There is a shut-off valve immediately at the water supply to the hose reel itself, which must be opened before use. An automatic valve is used in some hose winders, which means that when the hose is pulled out a few meters, it opens
> DK 181517 B1 automatisk for ventilen og dermed også for vandforsyningen til slangevinden, som nu er parat til indsats.> DK 181517 B1 automatically for the valve and thus also for the water supply to the hose reel, which is now ready for action.
Slangevinden skal iht. BR18 kapitel 21 — vand, samt DS 439 — Norm for vandinstallation, forsynes fra bygningens vandforsyning. Forsyningsledningen skal fremføres sådan, at de installerede slangevindere til enhver tid er tilsluttet tilstrækkelig vandforsyning. En slangevinde skal have en vandforsyning der er opretholdt i mindst 30 minutter.In accordance with BR18 chapter 21 — water, as well as DS 439 — Norm for water installation, the hose wind must be supplied from the building's water supply. The supply line must be routed in such a way that the installed hose reels are connected to an adequate water supply at all times. A hose reel must have a water supply that is maintained for at least 30 minutes.
En lækagesikring er en supplerende installation på brugsvandsinstallationen, der overvåger vandstrømmen. Hvis der registreres et abnormt gennemstrømningsforhold, i form af f.eks. rørbrud, utæthed i form af sivning eller lækage, aktiveres lækagesikring, som foretager en afspærring af vandtilførslen og varsler forud valgt personale om aktiveringen af lækagesikringen i bygningen.A leakage protection is a supplementary installation on the domestic water installation that monitors the water flow. If an abnormal flow ratio is detected, in the form of e.g. pipe break, leakage in the form of seepage or leakage, the leakage protection is activated, which shuts off the water supply and notifies pre-selected personnel about the activation of the leakage protection in the building.
Der kan anvendes flere forskellige typer lækagesikring, afhængig af i hvilken type bygning lækagesikringen installeres.Several different types of leakage protection can be used, depending on the type of building in which the leakage protection is installed.
Lækager i vandforsyningsinstallationer kan også forekomme i skjulte rørinstallationer, hvor det ikke umiddelbart vil blive registreret og i vådrum, f.eks. wc der løber. Lækage defineres som være et uønsket udslip af vand fra vandforsyningsinstallationen.Leaks in water supply installations can also occur in hidden pipe installations, where it will not be immediately detected and in wet rooms, e.g. toilet that runs. Leakage is defined as an unwanted release of water from the water supply installation.
I forbindelse med installation af slangevindere, så skal anvisningerne i bygningsreglement, vejledninger og standarder for området følges. Der henvises bl.a. til, at når der installeres lækagesikring, der ville kunne berøre vandtilførelsen for slangevinder når den aktiveres, skal der vælges en metode til overstyring af lækagesikring, således slangevinderanlægget overholder alle gældende krav.In connection with the installation of hose reels, the instructions in the building regulations, guidelines and standards for the area must be followed. Reference is made, among other things, to so that when leakage protection is installed, which could affect the water supply for the hose reel when it is activated, a method must be chosen to override the leakage protection, so that the hose reel system complies with all applicable requirements.
Afhængig af bygningens indretning og anvendelse, kan der anvendes forskellige metoder til at overstyre lækagesikringen og gennemføre en tvangsåbning af vandforsyningen i bygningen. Det skal overvejes hvilken type overstyring bygningen er egnet til, og hvad der rent fysisk kan gennemføres.Depending on the layout and use of the building, different methods can be used to override the leakage protection and carry out a forced opening of the water supply in the building. It must be considered what type of override the building is suitable for and what can be physically implemented.
2 DK 181517 B12 DK 181517 B1
Der findes flere typer af aktiveringsmetoder til overstyring af lækagesikringen.There are several types of activation methods for overriding the leakage protection.
Automatisk aktivering kan baseres på f.eks. et installeret automatisk brandalarmanlæg (ABA-anlæg), automatisk indbrudsanlæg (AlA-anlæg) eller selvstændige PIR-detektorer på kabelforbindelse til lækagesikringens kontrol- og indikeringsudstyr. Det er også muligt at basere etableringen af vandforsyningen til slangevinderen på en manuel aktivering af overstyringen, såsom aktiveringstryk placeret i eller ved skabet for slangevinden eller lågekontakt i skabslågen i skabet for slangevinden.Automatic activation can be based on e.g. an installed automatic fire alarm system (ABA system), automatic burglar alarm system (AlA system) or independent PIR detectors on cable connection to the leakage protection control and indicating equipment. It is also possible to base the establishment of the water supply to the hose winder on a manual activation of the override, such as activation pressure located in or near the cabinet for the hose winder or door switch in the cabinet door in the cabinet for the hose winder.
Problemet med de eksisterende løsninger er, at man for store ejendomme, såsom skoler, med mange brandskabe fravælger dem eller helt fravælger lækagesikring fordi løsningerne er installations- og omkostningstunge. Endvidere er fejllokalisering besværligt, såsom hvis et skab er blevet åbnet ved en fejl. I det tilfælde vil lækagesikringen jo være slået fra indtil fejlen er lokaliseret og udbedret.The problem with the existing solutions is that for large properties, such as schools, with many fire cabinets, they are not selected or leakage protection is not selected at all because the solutions are expensive to install and expensive. Furthermore, fault location is difficult, such as if a cabinet has been opened by mistake. In that case, the leakage protection will be switched off until the fault has been located and rectified.
EP2662501 beskriver et lækagesikringssystem til rørinstallationer til vandforsyning, der omfatter mindst én afspærringsventil og flowmåler anbragt i rørinstallationens fremløb. Afspærringsventilen er konfigureret til at være i en åben tilstand eller i en lukket tilstand. En kontrolenhed er konfigureret til at lukke eller åbne nævnte afspærringsventil. Endelig beskrives det, at en slangevinder kan være installeret med vandtilførsel fra rørinstallationen.EP2662501 describes a leakage protection system for pipe installations for water supply, comprising at least one shut-off valve and flow meter placed in the pipe installation's upstream. The shut-off valve is configured to be in an open state or in a closed state. A control unit is configured to close or open said shut-off valve. Finally, it is described that a hose reel can be installed with water supply from the pipe installation.

Detaljeret beskrivelse af opfindelsenDetailed description of the invention
Det følgende er ikke-begrænsende eksempler på udførselsformer, som falder under det generelle koncept.The following are non-limiting examples of embodiments that fall under the general concept.
Figur 1 viser de udvalgte bestanddele i et lækagesikringssystem i vandforsyningsinstallationer ifølge én eller flere udførselsformer af opfindelsen.Figure 1 shows the selected components of a leakage protection system in water supply installations according to one or more embodiments of the invention.
Lækagesikringssystemet omfatter en afspærringsventil 2 med tilhørende ventilaktuator 3 og flowmåler 1 anbragt i rørinstallationens fremløb.The leakage protection system includes a shut-off valve 2 with associated valve actuator 3 and flow meter 1 placed in the pipe installation's upstream.
Termen ”ventilaktuator” refererer til enhedens funktion af at åbne eller lukke ventilen, her afspærringsventilen 2. Afspærringsventilen 2 kan eksempelvis være en styrbar ventil, f.eks. en motorventil.The term "valve actuator" refers to the unit's function of opening or closing the valve, here the shut-off valve 2. The shut-off valve 2 can for example be a controllable valve, e.g. an engine valve.
Flowmåleren er fortrinsvist fjernregistrerbar fra en kontrolboks 4 operativt forbundet til ventilaktuatoren 3, som er forbundet til afspærringsventilen 2.The flow meter is preferably remotely detectable from a control box 4 operatively connected to the valve actuator 3, which is connected to the shut-off valve 2.
Kontrolboksen 4 kan være i stand til at overvåge afspærringsventilens 2 funktionalitet, eksempelvis via en ventilmonitor. Termen ”ventilmonitor” refererer til enhedens funktion af at monitorere ventilen.The control box 4 may be able to monitor the functionality of the shut-off valve 2, for example via a valve monitor. The term "valve monitor" refers to the device's function of monitoring the valve.
Kontrolboksen 4 kan yderligere omfatte en ikke vist afvikler, der i kombination med kontrolboksens styrelogik og rørinstallationens driftsbetingelser kontrollerer/overvåger ventilaktuatoren 3 under en given aktionssekvens. Herved etableres en slags indstillelig tilstandsmaskine, som kan vælge en ud af et endeligt antal mulige sekvenser under hensyn til de undervejs målte, registrerede, og fysiske forhold. På baggrund af start og gennemløb af aktionssekvensen kan lækagesikringssystemet udføre en række målinger ogThe control box 4 may further comprise a controller, not shown, which in combination with the control box's control logic and the operating conditions of the pipe installation controls/monitors the valve actuator 3 during a given action sequence. This establishes a kind of adjustable state machine which can choose one out of a finite number of possible sequences taking into account the measured, recorded and physical conditions along the way. Based on the start and completion of the action sequence, the leakage protection system can perform a number of measurements and
8 DK 181517 B1 dataopsamlinger til vurdering af afspærringsventilens funktionalitet og/eller rørinstallationens elasticitet og/eller tæthed.8 DK 181517 B1 data collection for assessing the shut-off valve's functionality and/or the pipe installation's elasticity and/or tightness.
Af Figur 1 fremgår det, at bygningens slangevindere c (her indbygget i individuelle skabe) er indkoblet forskellige steder i den almindelige brugsvandsinstallation, og at kontrolboksen 4 således ikke kan afspærre denne uden også at berøve slangevinderne c deres vandforsyning. Der skal derfor træffes foranstaltninger til at sikre vandtryk på slangevinderne c, når dette er påkrævet, uanset lækagesikringens status.From Figure 1, it appears that the building's hose reels c (here built into individual cabinets) are connected in various places in the general domestic water installation, and that the control box 4 cannot thus shut this off without also depriving the hose reels c of their water supply. Measures must therefore be taken to ensure water pressure on the hose reels c when this is required, regardless of the status of the leakage protection.
Kontrolboksen 4 overvåger bygningens vandforbrug ved signaler fra flowmåleren 1. Såfremt lækagesikringen konstaterer lækage, vil den give signal til ventilaktuatoren 3 om at lukke afspærringsventilen 2, med mindre tvangsåbne indgangen t er aktiveret.The control box 4 monitors the building's water consumption by signals from the flow meter 1. If the leakage protection detects a leak, it will give a signal to the valve actuator 3 to close the shut-off valve 2, unless the forced-open input t is activated.
I det tilfælde hvor lækagesikringen 4 allerede har afspærret installationen, vil denne blive genåbnet ved aktivering af tvangsåbne indgangen t.In the case where the leakage protection 4 has already blocked off the installation, it will be reopened by activation of the forcibly open entrance t.
Hvis kontrolboksens 4 net-forsyning svigter, vil ventilaktuatoren 3 ligeledes åbne afspærringsventilen 2. | den foreliggende opfindelse kan ovenstående foranstaltninger omfatte en radiomodtager 5 med en ”fail-safe” styreudgang for tvangsåbnesignal, og en magnetlågekontakt med tilhørende batteridrevne transpondere 6 indbygget i hvert slangevinderskab.If the mains supply of the control box 4 fails, the valve actuator 3 will also open the shut-off valve 2. | the present invention, the above measures can include a radio receiver 5 with a "fail-safe" control output for forced opening signal, and a magnetic door switch with associated battery-powered transponders 6 built into each hose winch cabinet.
Transponderne 6 er radiosendere, som hver især er tildelt et unikt serienummer.The transponders 6 are radio transmitters, each of which is assigned a unique serial number.
Hver gang en magnetlågekontakts status ændrer sig, idet et slangevinderskabs låge åbnes eller lukkes, så vil transponderen 6 udsende besked herom, tilsammen med sit individuelle serienummer.Every time the status of a magnetic door switch changes, as the door of a hose wining cabinet is opened or closed, the transponder 6 will send a message to this effect, together with its individual serial number.
Herudover vil transponderne hvert minut udsende en besked indeholdende det individuelle serienummer samt batteriets aktuelle polspænding (fx ”heartbeat message” eller ”keep alive message”).In addition, the transponders will send out a message every minute containing the individual serial number and the battery's current pole voltage (e.g. "heartbeat message" or "keep alive message").

Kontrolenheden med radiomodtager 5 er konfigureret til at lytte efter beskeder afsendt fra transpondere 6 med netop de serienumre, som er indbygget i ejendommens slangevinderskabe c. Såfremt en transponder 6 melder at brandskabets dør er åben, vil radiomodtageren 5 signalere tvangsåbning på udgangen O, som er konfigureret (fx forkablet) til at tvangsåbne indgang t på kontrolboksen 4, som i respons hertil er konfigureret til at give signal til åbning af afspærringsventilen 2 uanset dennes øjeblikkelige tilstand.The control unit with radio receiver 5 is configured to listen for messages sent from transponders 6 with the exact serial numbers that are built into the property's hose winch cabinets c. If a transponder 6 reports that the door of the fire cabinet is open, the radio receiver 5 will signal forced opening on output O, which is configured (e.g. pre-wired) to forcibly open input t on the control box 4, which in response to this is configured to give a signal to open the shut-off valve 2 regardless of its current state.
Såfremt radiomodtageren 5 savner to på hinanden følgende heartbeats fra en tilsluttet (konfigureret) transponder, så vil radiomodtageren 5 atter signalere tvangsåbning på udgang O.If the radio receiver 5 misses two consecutive heartbeats from a connected (configured) transponder, the radio receiver 5 will again signal forced opening on output O.
Det manglende heartbeat kan eksempelvis være forårsaget af en midlertidig obstruktion i radiosignalvejen eller af et udtjent batteri i transponderen 6.The missing heartbeat can, for example, be caused by a temporary obstruction in the radio signal path or by an exhausted battery in the transponder 6.
Såfremt modtageren 5 mister sin netforsyning vil modtageren ligeledes signalere tvangsåbning.If the receiver 5 loses its mains supply, the receiver will also signal forced opening.
Disse egenskaber tilsammen gør modtageren “fail-safe”, idet den beredskabsmæssigt sikre respons er at tvangsåbne afspærringsventilen 2, således der er vandtryk til slangevinderskabene.These properties together make the receiver "fail-safe", as the safe response in terms of emergency response is to forcibly open shut-off valve 2, so that there is water pressure for the hose winches.
Radiomodtageren 5 kan være udrustet med et display, hvori der eksempelvis vises hvilke transpondere 6, der melder om åbentstående låge; hvilke transpondere 6, der melder om lav batterikapacitet, og hvilke transpondere 6, der ikke modtages signal fra.The radio receiver 5 can be equipped with a display in which, for example, it is shown which transponders 6 are reporting on an open door; which transponders 6 report low battery capacity and which transponders 6 no signal is received from.
