Definitions

  • the present invention relates to an automatic opening system for natural ventilation roof units, comprised of a lever mechanism, a base and upper openable part, for the automatic opening of roof light lids, windows, hatches or other ventilation elements and could also be used for building ventilation, more specifically for the creation of smoke and / or hot gases free zones in the event of fire. It can also be used for daily ventilation.
  • the smoke and heat ventilation systems can create and maintain a smoke free layer above the floor by exhausting the smoke. They also could be used for the extraction of hot gases released in the event of fire, during its initial phase. The use of such systems could create smoke free zones before the smoke layer spreads. Their value has been firmly proven in the evacuation of people from buildings or other building sites, as well as in the reduction of smoke damage and financial loss. They can facilitate ease of access for extinguishing a fire by improving visibility, reducing temperature under the roof and by limiting the lateral spread of the fire. In order to obtain these benefits it is crucial for the vent systems to function both fully and reliably if and when needed during their lifetime.
  • the SHEVS is a safety system designed to play a positive role during any event of a fire.
  • Natural ventilation systems are smoke and heat exhaust systems which are designed to open using a set programme, after a fire has occurred. They can either be automatically or manually activated, or by using a combination of both. For a specific design, where only manual start-up is appropriate, the system can be installed without an automatic launching mechanism.
  • Natural ventilation systems should be fitted with self-powered opening mechanisms such as gas containers, spring systems, local power supply and / or external power supply.
  • Patent application GB2479883 A and patent application GB2479884 A discloses lever type ventilation systems designed for two-sided installation along the width of the smoke duct valve.
  • the systems disclosed in the two patent documents may be driven by an electric motor and have a locking mechanism for securing them in a closed position, while a cantilever system allows the upper openable part to open to about 140 degrees.
  • the ventilation systems under consideration have certain limitations regarding the basic parameters of their systems, according to the European standards, for example in the area of the smoke duct valves. They are only intended for an electromotor opening mechanism and not for a pneumatic actuator.
  • Patent applications GB2479883 A and GB2479884 A are inherently so-called tandem systems using two identical opening mechanisms at both ends of the valve. These mechanisms are mounted bilaterally, and single or unilateral use is not possible i.e. it is not possible to operate a single mechanism because it will twist the lid of the system.
  • the automatic opening system for natural ventilation roof units under current consideration is provided with a lever mechanism that is single and is centre mounted on the upper openable part of the SHEVS.
  • the closest invention to the present invention is the vent system as disclosed in EP 2 003 262 B1 .
  • the system disclosed in EP 2 003 262 B1 is a lever vent system driven by two actuators - an electric motor and a gas spring (plunger).
  • the system provides an opening of 60, 90 or 150 degrees from the duct.
  • the opening process is carried out by an electric motor in combination with one or two plungers.
  • the plunger system provides additional power to the motor at the moment of opening. This is necessary because the electric motor is fixed close to the hinges, giving an adverse leverage effect. For this reason, the energy required to be invested in opening and closing the system is very high.
  • the main effect of the combination of the used opening mechanisms is that a more compact motor is used and the ventilation system, respectively, is also more compact.
  • the system also has a locking mechanism for securely fixing the lid in a closed position.
  • the vent system disclosed in EP 2 003 262 B1 is adapted for two actuators - an electric motor in combination with one or two plungers (it is impossible to mount a pneumatic mechanism), while the present invention is adapted for only one type of opening mechanism, the possibility being to be driven by either an electric motor or a pneumatic mechanism.
  • all the above-described patent documents have limitations on the length-width parameters and their electrical parameters.
  • the opening mechanism of the ventilation system known from EP 2 003 262 B1 is located very close to the hinges, this design feature is disadvantageous in terms of the requirement to use a mandatory combination of an electrical, pneumatic, or hydraulic opening mechanism with one or more gas springs. This makes the known system more complex and more costly.
  • the objective of the present invention is to provide an automatic opening system for natural ventilation roof units comprising of a lever mechanism, base and upper openable part, for the automatic opening of roof light lids, windows, hatches and other ventilation elements that could be used for a natural ventilation, by providing a two-stage opening the upper openable part up to 90-95 degrees and up to 140 or 165 degrees, depending of the capacity of the electrical motor or pneumatic mechanism.
  • the system is designed for the exhaust of smoke and/or hot gases in the event of fire, as well as for daily ventilation.
  • the elements of the system are as follows:
  • the principle of operating the system consists of two stages in operating the opening mechanism.
  • the first stage means opening up to 90-95 degrees and the second stage means opening up to 140 or 165 degrees.
  • the lock type is one and the same in both positions - the first lock locks the upper openable part in the closed position and is self-unlocking when the opening mechanism is opened and the second lock is self-unlocking upon reaching the specified degrees of the opening angle.
  • the activation of the opening mechanism is carried through a control panel signal, a plurality of initiating signals for this activation may be used: a smoke detector, fire alarm control panel, button, building control system, etc.
  • the angle of the opening is determined by the size and type of the electric motor or pneumatic mechanism used, which in turn is proportional to the overall size of the system and which will affect its overall cost. Using a larger mechanism opens the system to a larger angle, but at an increased cost.
  • the angle of opening affects the aerodynamic efficiency of the system, i.e. what amount of smoke will be extracted per unit of time under certain conditions.
  • the preferred embodiments of the ventilation system include the opening of its upper openable part 8 by means of an integrated opening mechanism 2 based on electrical motor or pneumatic mechanism.
  • the electrical motor designated for opening the system is fixed to the fixed base lower support cross section 4 through the lever mechanism 3 in the slots of its main body.
  • the opening mechanism is attached to the upper openable part cross section 5 at the position of the lock 6.
  • the main body of the opening mechanism 2 is made of extruded aluminium, and has a movable stainless steel piston. Depending on the length of the opening mechanism 2, as well as its overall length when open, it assumes an angle of opening of between 140 and 165 degrees.
  • the ventilation system will open depending on the length of the used opening mechanism in order to obtain the desired opening angle, depending on the purpose and the designation of the system, i.e. is it for smoke extraction or for daily ventilation.
  • the pneumatic mechanism designated for opening the system is fixed to the fixed base lower support cross section 4 of the lever mechanism 3 at the slots of the main body of the opening mechanism 2.
  • the opening mechanism 2 is attached to the upper openable part cross section 5 at the position of the lock 6.
  • the main body of the opening mechanism 2 is made of extruded aluminium and has a movable stainless steel piston. Depending on the length of the opening mechanism 2, as well as its overall length when open, it assumes an opening angle of between 140 and 165 degrees.
  • the ventilation system will open in respect to the opening mechanisms used 2, there is the possibility of using mechanisms of different lengths (in opened and closed positions) in order to obtain the desired opening angle, depending of the purposes and the designation of the system, i.e. if it is for smoke extraction or for daily ventilation.
  • the system can only be used for smoke exhaustion having only one type of opening - up to the maximum opening angle.
  • two-stroke (open/close) pneumatic mechanisms are used and the system works by opening and closing only at the two endpoints - i.e., fully open and fully closed. With this design, the signal is single and continues to fully open the system to reach the maximum desired angle.
