Description

538 2 Sakerhetsmanlucka Tekniskt omrade Uppfinningen avser en manlucka for vatskecisterner, exempelvis dricksvattencistemer eller oljecisterner. Manluckan omsluter en lasanordning och en elektrisk kontaktanordning som avger en larmsignal vid forcering eller Oppning av luckan. Technical field Technical field The invention relates to a manhole for liquid tanks, for example drinking water systems or oil tanks. The manhole cover encloses a locking device and an electrical contact device which emits an alarm signal when forcing or opening the door.

Teknikens standpunkt Manga typer av vatskecisterner, exempelvis dricksvattencisterner är, forutom i tatorter, ofta placerade pa mera avlagsna platser utan kontinuerlig bevakning. Cistemerna maste vara forsedda med en manlucka som medger inspektion och rengOring av cisternen men utgOr i allmanhet det ur sakerhetssynpunkt svagaste partiet pa cisternen. En forcering eller Oppning av luckan ger atkomst till cisternens innehall, vilket da kan kontamineras med frammande amnen, t.ex. gifter av olika slag, vilket kan leda till katastrofala fOljder fOr anvandarna av t.ex. dricksvatten. Om cisternen innehaller farliga och samtidigt stoldbegarliga vatskor, som t.ex. raolja, är ett obehorigt intrang av bade sakerhets och ekonomisk betydelse. Vid cisterner som är fOrsedda med manluckor som är relativt svarforcerade och är lasta med yttre hanglas, medfor en forcering eller Oppning snabbt access till cisternens innehall. For att Oka den tid som en angripare miste ha for aft fullborda ett intrang i en cistern sa kravs, dels en manlucka som är mycket svar att bryta upp dels att vid ett angrepp genom uppbrytningsfOrsa, genomborrning eller genomsagning, en larmsignal omedelbart utlOses av aktiviteten i fraga och att tankens manOppning fortfarande dr tackt. Luckan maste ocksa sluta tatt mot manhalets sarg for att forhindra luftgenomstromning vid tryckvaxlingar inuti cisternen, vilket kan medfOra att fOroreningar oavsiktligt nár cisternens inre. Det finns ett antal utfOranden av manluckor med mer eller mindre lattatkomliga och latt forcerade lasanordningar och signalgivare som aktiveras da luckan pa ett eller annat satt Oppnas, men som ger omedelbar access till cisternens inre 1 538 2 Problemkisning FOreliggande uppfinning lOser problemen med kand teknik genom aft den har de i de efterfoljande patentkraven angivna kannetecknen. Prior art Many types of water tanks, such as drinking water tanks, are, in addition to taverns, often located in more remote places without continuous monitoring. The cisterns must be fitted with a manhole which allows inspection and cleaning of the cistern but is generally the weakest part of the cistern from a safety point of view. A forcing or opening of the door gives access to the contents of the cistern, which can then be contaminated with foreign substances, e.g. toxins of various kinds, which can lead to catastrophic consequences for the users of e.g. drinking water. If the cistern contains dangerous and at the same time desirable water shoes, such as crude oil, is an unauthorized intrusion of both safety and economic significance. In the case of cisterns which are provided with manhole covers which are relatively forced, and which are loaded with outer male glass, forcing or opening means quick access to the contents of the cistern. In order to increase the time that an attacker may have to complete an intrusion into a cistern, it is a requirement, partly a manhole that is very responsive to break up and partly that in the event of an attack by breaking force, piercing or sawing, an alarm signal is immediately triggered by the activity in question and that the man of thoughtOpening still dr thanked. The door must also stop against the manhole rim to prevent air flow during pressure changes inside the cistern, which can cause contaminants to inadvertently reach the interior of the cistern. There are a number of embodiments of manhole covers with more or less easily accessible and easily forced reading devices and signal transmitters which are activated when the door is opened in one way or another, but which provide immediate access to the interior of the cistern. it has the pitches specified in the appended claims.

Figurforteckning Figur 1 visar en manlucka i upplast och uppfallt lage Figur 2 visar ett snitt genom en kontaktanordning fOr larmsignal Figur 3 visar en vy av ena delen av en lasmekanism i last lage Figur 4 visar en vy av andra delen av lasmekanismen Detaljbeskrivning av uppfinningen Manluckan 1 enligt uppfinningen ar med gangjarn svangbart anordnad i strukturen pa ovansidan av en stor vatskebehallare, exempelvis en dricksvattencistern. Manluckan best& av en yttre lucka 2 med nedvikta kanter 3, som omsluter en inre sarg 4 pa en bottenplatta 5, vilken har en yttre sarg 6, som dá den yttre luckan ar nedfalld, omsluter dennas nedvikta kanter. lnuti den yttre luckan 2 och elektriskt isolerat fran denna sitter en inre lucka 7. I vardera av den inre luckans fyra hOm är isolatorer 8 fasta med skruvar 9 (se fig. 2). Figure 1 Figure 1 shows a manhole in loaded and striking position Figure 2 shows a section through a contact device for alarm signal Figure 3 shows a view of one part of a welding mechanism in load bearing Figure 4 shows a view of the other part of the welding mechanism Detailed description of the invention Manhole 1 according to the invention, hinges are pivotally arranged in the structure on the upper side of a large water container, for example a drinking water cistern. The manhole cover consists of an outer lid 2 with folded edges 3, which encloses an inner rim 4 on a bottom plate 5, which has an outer rim 6, which when the outer lid is folded down, encloses its folded edges. Inside the outer cover 2 and electrically insulated from it is an inner cover 7. In each of the four holes of the inner cover, insulators 8 are fixed with screws 9 (see fig. 2).

Isolatorerna 8 ar inskjutna i spiralfjadrar 10, vilka ar taste i den yttre luckan. Den yttre luckan har ett antal runt sina kanter jamnt fordelade platvinklar 11, vilka skjuter in under kantema pa den inre luckan. Darigenom bildar den yttre luckan och den inre luckans platvinklar ett antal kontaktpunkter som sluter en elektrisk strOmkrets nar luckan Oppnas. StrOmkretsen sluts aven om den yttre luckan forceras med ett verktyg som är elektriskt ledande. En signal avges i bada fallen till en larmanordning som sander en signal till en avlagsen, fOretradesvis bemannad larmcentral. Vid stangd lucka är strOmkretsen Open och den inre luckan pressas av tjadrarna10 med eft runtom jamnt fOrdelat tryck mot den inre sargen 4 vilken er forsedd med en elektriskt isolerande tatningslist 12. For att fa access till tankens inre kravs saledes att aven den inre luckan forceras, vilket ger en tidsfrist efter aft larmsignalen utlosts vid forcering av den yttre luckan. 2 538 2 Inuti den yttre luckan 2, innanfOr dess framre kant sitter en lasanordning som innefattar ett hangres 13 vars bygel 14, som är tradd genom ett 14 15 i en till den yttre luckans insida fixerad konsol 16, är forbunden med en fOrsta skjutregel 17 och en andra skjutregel 18. Bada skjutreglarna stacker sig till fOrsta dubblal6sOglor 19 och 20 och den forsta skjutregeln stracker sig till andra dubbla lasOglor 21 och 22 (se fig. 3) . De !pada skjutreglarna ar fixerade till varandra med lankar 23 och 24 och till hangla'set14. LasOglorna är med ett avstand fran varandra fasta pa konsolen 16. The insulators 8 are inserted into coil springs 10, which are keyed in the outer cover. The outer door has a number of evenly distributed plate angles 11 around its edges, which project under the edges of the inner door. Thereby, the outer cover and the flat angles of the inner cover form a number of contact points which close an electrical circuit when the cover is opened. The circuit closes even if the outer cover is forced with a tool that is electrically conductive. A signal is given in both cases to an alarm device which sends a signal to a remote, preferably manned alarm center. When the door is closed, the circuit is open and the inner door is pressed by the tadpoles 10 with evenly distributed pressure against the inner rim 4 which is provided with an electrically insulating sealing strip 12. In order to have access to the inner requirements of the tank so that the inner door is also forced. which gives a time limit after the alarm signal has been triggered when forcing the outer door. Inside the outer cover 2, inside its front edge there is a locking device comprising a hanger 13 whose stirrup 14, which is threaded through a 14 in a bracket 16 fixed to the inside of the outer cover, is connected to a first sliding bar 17 and a second slider 18. Both sliders extend to the first double locks 19 and 20 and the first slider extends to second double locks 21 and 22 (see Fig. 3). The two sliders are fixed to each other with lanes 23 and 24 and to the hanger set14. The laser eyes are fixed to the bracket 16 at a distance from each other.

Dá luckan stangs grenslar de tva dubbla fOrstal6sOglorna tva enkla tredje och fiarde lasoglor 25 och 26, som är fasta be den inre sargens 4 framre utsida och skjutreglarna kan darefter med hanglaset skjutas genom de fOrsta, andra, tredje och fjarde lasOglorna. Henglaset kommer dà att vara helt inskjutet (position A i fig. 3) i en oppning 27 pa' den yttre luckans sida och hanglasets lasmekanism ãr aktiverad. Den nedre kanten pa den yttre luckans nedvikta kanter 3 bottnar innanfOr bottenplattans 5 yttre sarg 6 och blir darmed oatkomlig f6r uppbrytningsfOrsok. 'lid upplasning dras hanglaset utat (till den streckade positionen B i fig. 3) med lasets nyckel varvid skjutreglarna 17 och 18 medelst en vid den fOrsta skjutregeln 18 fixerad hake 28 dras ur I AsOglorna 19 och 20 resp. 21 och 22 varvid den yttre luckan frigors och de !Ada luckorna kan svangas upp. 3 When the door is closed, the two double front eyepieces branch two single third and fourth laser eyeglasses 25 and 26, which are fixed to the front outside of the inner rim 4, and the sliding bars can then be slid with the male glass through the first, second, third and fourth laser eyeglasses. The hanging glass will then be completely inserted (position A in Fig. 3) in an opening 27 on the side of the outer door and the welding mechanism of the hanging glass is activated. The lower edge of the folded edges 3 of the outer cover bottoms inside the outer edge 6 of the bottom plate 5 and thus becomes inaccessible to breakage attempts. When unloading, the male glass is pulled outwards (to the dashed position B in Fig. 3) with the weld key, the sliding bars 17 and 18 being pulled out by means of a hook 28 fixed to the first sliding bar 18. 21 and 22, whereby the outer cover is released and the additional doors can be swung up. 3
