Description

Technical field

The invention relates to a method of solving a hydrological device for catching and utilizing rainwater from flat roofs for fire purposes.

BACKGROUND OF THE INVENTION

Water is becoming a strategic raw material and its optimal use is increasingly important. It is also related to climate change, which in our climate zone causes uneven sums of rainfall, heavy rainstorms or windstorms. dry, which is reflected in low flow rates in rivers and low groundwater levels. Thus, water storage and use during the period without rainfall becomes important. It is therefore necessary to use water efficiently according to its nature, which applies to rainwater that has a great potential for use. The current state of water management shows that rainwater is drained from flat roofs through internal vertical sewage and subsequently horizontal sewerage a. drains into sewer or recipient. In a single sewer system (a common system for draining all sewage: sewage, industrial sewage and rainwater), rainwater during rainfall reduces the flow rate of the sewage system through sedimentation and. burden the sewage treatment plant. In the case of sewerage systems, rainwater is drained directly to the recipient (catchment area) without any use. Thus, the amount of rainwater flows without use into the river basin. Consequently, industrial enterprises can collect and use this water from the catchment or use drinking water from the pipeline system. Generally, drinking water is used for fire-fighting purposes in buildings, for plumbing in sanitary facilities (VC) and for various technological purposes, or for cleaning and irrigation of premises. This solution is uneconomical because it does not use the available rainwater. Recently, in the case of new constructions, the collecting of rainwater is solved according to the requirements of the sewerage administrators by the solution of storage retention tanks. Water reservoirs are based on underground reinforced concrete tanks, metal structures, but on the basis of hardened plastics or, respectively, contrasts are very preferred. Rainwater collection solutions for family houses are offered, and there are no adequate solutions for industrial construction yet. Abroad, water and sewage savings through rainfall systems are widespread and a common element of savings. In Slovenia, for example, 90% of new family houses are handed over with a rainwater storage tank, and these systems are also subsidized in some countries.

The use of rainwater is suitable from flat roofs with foil insulation, metal or plastic coated roofing, as relatively clean and soft water remains. Water contamination is only organic impurities blown by the wind. It is not recommended to collect water from green flat roofs and asphalt roof surfaces, as hunuisoid parts are washed out and the water is acidic. Rainwater is also acidic water because water contains dissolved CO2 which it absorbs when it passes through the atmosphere. In the summer months, rainwater may occasionally be sensitized by sensitive persons or may cause a slight build-up. If rainwater is used in toilets, these sediments may interfere visually (another color of the sanitary ware - not bright white) is the solution. But this is a problem of good mechanical filtration.

As long as rainwater is fed from the roof to the underground tank and stored in the dark, it retains high quality for a long time and organic reactions do not take place there. Rain water from paved areas of car parks and roads is not suitable due to possible oil impurities to be mixed with water from roofs, therefore the only solution will be the use of water from flat roofs.

SUMMARY OF THE INVENTION

Hydrological equipment for collecting and utilizing rainwater from flat roofs is a complex system for rainwater purification, capture and accumulation, condition monitoring and use especially for fire purposes. The essence of this patent of a hydrological device for collecting and utilizing rainwater from flat roofs for fire purposes in buildings consists of an external roof drain with a protective basket for catching coarse dirt, which can also be equipped with electric heating for winter. A vertical downpipe with a cleaning piece located approx. 900 mm above the floor is connected by a downpipe with a filter to catch fine dirt. Through the supply piping, the water flows through gravity into the underground storage tank - the fire water storage tank, where the inlet is in the bottom part of the tank with a rounded pipeline to ensure a swirling inlet and water circulation. The water reservoir is stored in the freeze depth below the terrain and is accessible through the inspection shaft with a hatch. This input is also necessary for maintenance, monitoring the status of the fire water and possible direct connection of the fire equipment via suction accessories for intervention. For this purpose, an access road with a paved area for fire trucks must be built to the fire water tank. In the upper part of the tank there is an overflow drain into the drenblocks. Marrow block is a device for smooth and natural infiltration of rainwater into the ground.

The system is based on the ventricular principle, which on the one hand allows any amount of rainwater to be handled and on the other hand eliminates the clogging and annihilation of the system. There is a water level sensor in the fire water tank, which transmits the information to the personal computer. Monitoring of the quantitative status (level of rainwater) also serves as a critical condition, when water loss would prevent its functional use, therefore it is necessary to interconnect systems using fire water also to public drinking water supply (back-up source).

The water is taken from the fire water tank through a piping system to an automatic pressure station (with a back-up pump and also with a back-up power supply) in the building, from where it branches into a fire main with discharge to internal and external hydrants , drenchers, etc.). The dimensioning of the fire water demand and the above mentioned technical equipment is necessary according to the respective STNs, whereby it is possible to interconnect the fire water storage tanks with more: rainwater pipes or, if necessary, to design several storage tanks.

Industrial usability

The use of water for fire purposes is determined by Decree of the Ministry of the Interior of the Slovak Republic of 10 December 2004 no. 699/2004 Coll. on water supply for fire fighting. Thus, fire water could be used in fire water storage tanks as a permanent supply of fire water and from there in external and internal fire mains. Use also in water distribution systems for water stable fire extinguishers (sprinklers, drenchers) according to the Decree of the Ministry of the Interior no. 169/2006 Coll. on the specific characteristics of the fixed fire-extinguishing equipment and the semi-stable fire-extinguishing equipment and on the conditions for their operation and ensuring their regular control.

Hydrological equipment for collecting and using rainwater from flat roofs for fire purposes is useful for protecting buildings from fires, protecting the environment and creating intelligent water management and management systems. At the same time, it is important in the economical utilization of rainwater and saves on the costs of sewerage. The mentioned hydrological equipment is connected to the building monitoring and control system. The system for the use of rainwater can be used not only in new buildings, but also in the reconstruction and renovation of buildings.
