Definitions
- the present invention relates to a security device for water tower and a water tower equipped with said security device.
- the water tower is a link in the water production and distribution network, it is most often located on the outskirts of agglomerations even if it can also be located in the city center as in the open countryside.
- the role of a water tower is to ensure the storage of drinking water for distribution, it allows to regulate the pressure of the water thus ensuring a homogeneous distribution throughout the network.
- a water tower must be elevated compared to the dwellings it serves.
- a water tower must be built on a relief, or in the absence of relief, the water tower must be raised artificially which requires to build the latter on a support.
- a water tower 1 consists of a support 10, most often in the form of a tower with or without symmetry of revolution. At the top of this support 10, is placed in elevation a tank 2 serving as a water reservoir E.
- the support 10 of the water tower may comprise several levels of floors 11 or intermediate levels spaced in height in the body of the 'work.
- Access means 12 in the form of ladders or stairs provide access to all levels, including access means 13 to the tank to facilitate maintenance.
- the tank 2 generally has the same as the support 10 a symmetry of revolution.
- the tank 2 of a water tower has a maximum filling level 20a and a minimum filling level 20b.
- the water towers being geographically dispersed, they are of interest in the fight against fires by serving as water reserves usable by firefighters. Thus a certain quantity of water must always be at their disposal whether the tank is full or at its minimum level. To do this, all the tanks 2 have a reserve -fire- 20c.
- the tank-2 is generally provided with two level pears, a high level pear 21a and a low level pear 21b, which make it possible to control the quantity of water contained in the tank and to check that it is not either too full or close to its minimum level.
- the minimum filling level of the tank corresponds to the amount of water serving as fire reserve 20c.
- two pipes one for supplying water 22a and taking water 22b, connect the tank to the rest of the water distribution network and also make it possible to regulate the level of the water in the tank.
- An access chimney 23 passes through the bottom of the tank 2 and raises the latter so that the upper edge 24 of said access chimney is higher than the maximum filling level of the tank.
- the access means 13 to the tank 12 pass through this stack to allow maintenance personnel to ensure the verification of the state of the tank and its cleaning.
- the water tower In order to protect the contents of the tank from bad weather, the water tower is covered with a roof. 3.
- the water towers being elevated points in the landscape, they constitute perfect places of implantation among others for antennas resignation. This material is attached to the roof 3 of the water towers.
- water towers 30 In order to be able to maintain it or to monitor the state of the roof 3, it was necessary to equip the roofs with water towers 30 giving access to this equipment.
- the hatch 30 is accessible through access means 13 which are either the same as those leading to the tank 2 and which have been extended to reach the under roof or new access means which extend from a platform attached to the top of the access chimney 23 (not shown in Figure 1) to the under roof.
- a problem with water towers lies in the fact that many people, other than the water distribution agents, are brought to approach the tank containing drinking water.
- a padlocked door located at the foot of the support, prevents access to the infrastructure of the water tower and including the drinking water tank. This door can be easily fractured by malicious people in order to pollute the water in the tank.
- An object of the present invention is to provide a device for blocking access to the tank even if an intruder or a wild animal has been able to get inside the water tower.
- a securing device for a water tower of the type comprising a support, an elevated tank placed on said support, said tank ensuring the storage of the water for distribution, a roof covering said tank, the support being provided with means for access to the tank and an access hatch formed in the roof, an access chimney passing through the bottom of the tank, said access means extending at least partially in said chimney; access, characterized in that said securing device comprises a closure means incorporating at least one selectively mobile part allowing access to the inside of the tank, said closure means extending in the extension of the chimney of access to the access hatch at the level of the under-roof, to isolate the interior of the tank of the access chimney and the access hatch to the roof.
- said access door is located vertically to the access chimney, said closure means bearing on the upper edge of said access chimney and being fixed to the under-roof around the trapdoor. access.
- said selectively movable portion of the closing means is slidably mounted in a lower guide rail disposed on the upper edge of said access chimney or on a platform on which said chimney would open. access and in an upper guide rail attached to the under-roof.
- said relatively movable portion of the closure means is provided with rolling means for rolling along a lower guide rail disposed on the upper edge of said access chimney or on a platform on which to emerge. said access chimney and along an upper guide rail fixed to the under-roof.
- said access door is offset transversely relative to the access chimney, said closure means resting on a platform fixed in a console to said access chimney and being fixed to the under-roof .
- the closure means is constituted by a plurality of moving parts in the form of vertical slats hinged together and guided by the guide rails, said movable parts wrapping around a reel contained in a housing attached to the access chimney or platform.
- the closure means consists of at least two distinct parts, one of these parts being movable, the other being fixed, the mobile part (s) being suitable ( s) to retract into the fixed part.
- the closing means consists of two coaxial half-cylinders of which at least one is movable, the outer diameter of the first half-cylinder being smaller than the inner diameter of the second half-cylinder in order to retract at least partially in said second half-cylinder by relative rotation.
- the other of the two half-cylinders can be even fixed.
- the closure means is provided with at least one locking means for maintaining said closed closure means either by connecting it to a portion of the chimney or by connecting two constituent parts of said closure means.
- the invention also relates to a water tower of the type comprising a support, an elevated tank placed on said support, said tank ensuring the storage of water for distribution, and a roof covering said tank, the support being - equipped with means-access to the tank and an access hatch in the roof, an access chimney passing through the bottom of the tank, said access means extending at least partially in said access chimney, characterized in that it is equipped with the securing device as defined above.
