Definitions

  • This invention relates to a manhole cover for dustproof Closing a shaft, in particular a well shaft.
  • Such Well shafts for the collection of spring water, also called fountain parlors usually consist of a standing concrete pipe several meters deep or Cement pipe, which is tapered to a manhole at the top and with a Manhole cover is covered.
  • the shaft diameters are usually 60cm, 70cm, 80cm, or in some cases even 100cm.
  • the lid of one The shaft must be removable or hinged to allow access for Allow cleaning work in the shaft because it changes over time Accumulate sludge, which is drawn into the shaft from the water become.
  • the manhole cover must not close the manhole airtight, to equalize the pressure between the inside of the shaft and the To allow outside air pressure. But it must be prevented that any Bacteria, dirt, insects or other small animals in the shaft can penetrate, otherwise the water in the reservoir would be contaminated.
  • manhole covers for closing such a manhole are attached to the edge of the shaft with a hinge and with a lock lockable so that the shaft cannot be easily opened by unauthorized persons can.
  • To ventilate the shaft there is usually one in the manhole cover Insect or dust filter built in to prevent the ingress of dirt and To prevent bacteria carriers in the shaft.
  • the closed manhole cover lies on a with a seal located on the inside of the lid Support ring made of metal on the top edge of the shaft pipe is embedded, in such a way that the support ring the cement pipe end slightly towering upwards.
  • a disadvantage of conventional manhole covers is that the Hinges are knocked out or even bent over time, and then at When the lid is closed, the seal is no longer exactly on the support ring lies on. If the lid with its regular opening If the weight is dropped back into the hinge, this becomes excessive claims and shows play over time. On the other hand, if the lid Closing dropped and something is accidentally on one side on the support ring, the hinge can bend. In both cases This can result in the seal no longer being clean when the lid is closed rests on the support ring so that the shaft is no longer in the end is sealed dustproof. Because the manhole covers are opened regularly to carry out the necessary cleaning and service work in the To be able to carry out wells are the seals of such manhole covers exposed to a correspondingly high mechanical load and can easily be damaged.
  • one Manhole cover for the secure and dustproof sealing of a manhole in Form of a standing cement pipe, in particular a well shaft create that allows frequent opening and closing of the shaft without that affects the sealing properties of the manhole cover and a dust-proof and safe covering of a shaft enabled for a long time.
  • the manhole cover consists of a Support ring 14 made of stainless steel, which is made of flat steel 16 the same material is mounted on the shaft, here a cement cone 11, and an associated cover 1.
  • the flat steels 16 are used for assembly of the support ring 14 screwed from the inside to the shaft wall.
  • the support ring 14 is sealed against the edge of the shaft by means of a silicone compound.
  • the inner wall of the shaft 11 is advantageously slurried with white cement, so that it does not absorb water and also not with a coat of paint must be provided, what because of the desired food authenticity of everyone Parts with which the water comes into contact would be problematic.
  • This chrome nickel steel manhole cover 1 consists of a bowl-shaped arched manhole cover 2 and a flat cover plate 3. This is in the example shown by means of four screws or bolts 7, which on the Are welded, stored and inside of the manhole cover cap 2 positioned. Spiral compression springs 8 are located on these screws or bolts 7 put on, which always covers the cover plate 3 from the manhole cover cap 2 push away. Is pressed from below against the cover plate 3, the Compression springs 8 compressed and the cover plate 3 is against the Manhole cover cap 2 moves.
  • cover plate 3 On the underside of the cover plate 3 is a Sealing ring 4 laminated from a foam rubber permitted for food.
  • the cover plate 3 has a protruding downward along its circumference Collar 13, along the inside of which the sealing ring 4 extends.
  • Downtown the cover plate 3 has a ventilation opening, and is over this screwed from below a can-shaped perforated container 20, in the There is a paper filter inside. Between the manhole cover cap 2 and the cover plate 3 can air from the outside through this opening and then through get the filter inside the shaft and vice versa.
  • guide tabs 18 are mounted and between them a lock cylinder 10 with key 22 with a radial against the center of the Manhole cover cap 2 built-in bolts installed.
  • the guide tabs 18 lay around Pipe section 17 on the support ring 14 and center the manhole cover if necessary.
  • the cover plate 3 lies with the sealing ring 4 exactly on the upper edge of the support ring 14.
  • the seal 4 is from the Compressed spring-loaded cover plate 3 evenly on this edge pressed and thus ensures an airtight seal.
  • the key 22 can be turned on the lock cylinder 10 and the bolt is pushed inside the pipe section 17, after which the lid is securely locked.
  • Figure 2 shows the manhole opening with the pivotable manhole cover 1 is closed, in a cross section.
  • the manhole cover 1 consists of the arched manhole cover cap 2, which is open at the bottom, and the cover plate 3.
  • the diameter of the manhole cover cap 2 is selected so that it has the Cover plate 3 and the outer edge of the shaft pipe 11 slightly exceeded. This ensures that the rainwater is outside the shaft expires and drains.
  • the diameter of the cover plate 3 is chosen so that it slightly smaller than the outside diameter and larger than the inside diameter of the Shaft pipe 11 is.
  • the cover plate 3 is loaded by compression springs on the bottom open side of the manhole cover cap 2 mounted. For this purpose Screws or bolts 7 on the inside of the manhole cover cap 2 welded outside the outer diameter of the cover plate 3.
  • the Cover plate 3 has corresponding ears 12 with holes drilled through it, such that when inserting the cover plate 3 in the manhole cover cap 2 the Ends of the screws 7 are inserted through the holes in these ears 12.
  • the compression springs 8 space the cover plate 3 from the manhole cover cap 2 and by the nuts 19 screwed onto the screw ends, the Cover plate 3 held. Is pressed from below against the cover plate 3, so the compression springs 8 are compressed and the cover plate 3 is against the manhole cover cap 2 shifted out. When relieving the cover plate 3 it takes its original position, that is, it lies on the nuts 19 on. Compression springs are usually used, which have a travel of allow about 5mm to 10mm.
  • the number of screws 7 for storage and Positioning of the cover plate 3 can be different. In the shown Execution hold four screws 7 distributed around the circumference Cover plate 3. But it is also conceivable that the cover plate 3 with more or but is also held with fewer screws 7. In a simple version can even be dispensed with the screws 7, and the springs are direct firmly connected to the cover plate 3 and the manhole cover cap 2. For one such execution is a solution with even only one in the center of the Cover plate 3 mounted spring conceivable.
  • the cover plate 3 has the The side facing the shaft edge has a welded-on tire on it Collar 13 forms. Along the inside of this collar 13 is the rubber seal 4 glued to the cover plate 3.
  • the collar 13 causes the seal 4 can not slip when pressed on the edge of the manhole, and that it in front mechanical damage is protected. Furthermore, the cover plate 3 this collar 13 provides additional torsional stability.
  • a pipe socket 21 which has an opening 5 for pressure equalization between the inside of the shaft and the atmosphere.
  • a perforated box 20 is screwed over this opening 5 into which an air filter 6 is inserted.
  • This air filter 6 allows the exchange of air between the shaft and the outside air without dust, dirt or insects in the locked shaft can penetrate.
  • the closed manhole cover 1 lies with his Cover plate 3 and the rubber seal 4 thereon on the support ring 14 on.
  • This support ring 14 is firm and tight with the shaft pipe 11 connected.
  • the shaft pipe 11 is longitudinal at the upper end of the inner circumference on a recess 15, in which the support ring 14 is inserted is.
  • the inner diameter of the support ring 14 corresponds to the inner diameter of the shaft pipe 11.
  • the remaining free space of the recess 15 between the The shaft pipe and the support ring 14 are filled with mortar or silicone compound.
  • the manhole cover 1 is pivotable on the hinge 9 Support ring 14 articulated.
  • This hinge 9 consists of two on the support ring 14 welded flat iron. Likewise are on the outer edge of the manhole cover 2 two flat irons welded on. These parallel flat bars have a hole through which a screw is inserted and with a nut is secured, and which forms the axis of the hinge. About this axis the manhole cover 1 is pivoted when opening and closing.
  • the support ring 14 On the On the opposite side of the hinge, has a welded-on, radially outwardly extending pipe section 17, the one Has a diameter of about 2 cm.
  • two guide tabs 18 welded.
  • This two guide lugs 18 run downwards in a V-shape and are arranged that when the manhole cover 1 is closed, the pipe section 17 between the two guide tabs 18 come to rest. This ensures that the Manhole cover 1 and thus the cover plate 3 with the seal 4 in the center the support ring 14 rests.
  • the cover plate 3 is now permanently pressed against the support ring 14 by the springs 8 pressed, causing a uniform load on the seal 4 of the cover plate 3 is reached.
  • the shaft covered with the manhole cover 1 according to the invention is thus locked and locked securely and dustproof.
  • the seal 4 is one less heavy mechanical stress when opening and closing exposed than with conventional manhole covers, and the risk of Damage is significantly reduced. This has the consequence that Contamination of the shaft caused by defective seals or not lids correctly resting on the support ring 14 were caused by the use of the manhole cover according to the invention can be prevented can.
  • manhole cover 1 The materials used for manhole cover 1 are all food safe. So is included for the metal parts of the manhole cover 1 all screws, nuts, tabs, bolts and springs and also for the Support ring 14 stainless steel, preferably Cr-Ni steel A2 1.4301 used. Likewise, the sealing materials used such as the silicone adhesive and the Rubber seal 4 especially permitted for food. This is necessary because in Inside the shaft and on the cover plate 3 forms condensed water runs back into the shaft and thus reaches the water reservoir. For the external parts, the use of stainless steel has the advantage that the parts do not have to be treated with rust protection, and that they are very weather resistant.
