Description

System for preventing emergencies of utility networks

The utility model relates to engineering networks of water supply, gas supply and electricity supply and can be used to prevent emergencies in the absence or presence of a person in the room, in particular flooding of the premises with liquid, filling the room with gases or a short circuit in the mains during outages or interruptions in supply water, gas, electricity to the facility, in the event of a break, failure, violation of the tightness or reliability of the connections, as well as leaving without additives reflection of the human factor. The utility model can be used both in the complex for all available engineering networks, and only for one of all available, to choose from.

The well-known sanitary-technical water supply system for residential and public buildings (Isaev V.N. et al. Design and installation of sanitary-technical systems for buildings. - M.: Higher School, 1984. - S. 175-176, Fig. 98), which includes a pressure head water supply pipeline with an extensive network of individual water consumers (washbasins, shower, etc.) provided with water-folding fittings.

A disadvantage of the known system is the possibility of flooding with water from the water supply network through water fittings, since the latter is not equipped with devices for emergency shutdown of the water supply during abnormal operating modes of the water supply network (discharge mode of water supply, re-supply of water after a break, with taps left, pressure drops in network, failure of water fittings, etc.).

A device for protecting rooms from flooding premises with water from the water supply network [USSR Author's Certificate Ns 1678991, IPC EOZZ 1/04, publ. 09/23/1991], comprising a body with inlet and outlet channels, a positive buoyancy ball valve, a valve seat located across the body, and a valve return mechanism with a stem, in which the valve return mechanism is provided with a bellows mounted on the body in its lower part, while the ball valve is fixed on the upper end of the rod, the lower end of which is placed in the bellows cavity.

The disadvantage of this device is its low reliability due to the possibility of the bellows rupturing by the water pressure in the network, as well as the failure of the ball pop-up valve when the tap is closed in case of failure of the last or a sharp increase in pressure in the network, since the water column remains in the body and the ball valve is located in pop up position. In addition, this device has limited functionality, due to the absence of an emergency shutdown of water during a discharge mode in a plumbing installation and breakthrough of taps, as well as during flooding in the event of an open taps being left open.

The closest in technical essence is the system of protection against emergencies of the engineering water supply network "Gidrolock (Hydrolock)" (Internet resource http://gidrolock.com.ua). The system consists of three main elements: water leakage sensors, a control unit and ball actuators designed for emergency shutdown of water. The control unit is designed to generate the supply voltage of all sensors connected to it, to control ball electric drives and to supply an audio signal about accident. The sound notification is activated when the system detects a water leak. In normal condition, the beep is turned off. Water sensors are installed in places of its likely occurrence: under the bathtub, sink, next to the toilet or sink, under the washing and dishwasher, battery or heating boiler, boiler, etc. Electric ball valve is designed to shut off water supply (heating) in case of leakage. The ball electric drive consists of a ball valve and an electric drive designed for remote control of a ball valve. Ball electric drives are installed on risers of hot and cold water (or heating system) after manual valves in places convenient for installation and maintenance.

The principle of operation of the Gidrolock system is as follows: when moisture enters the water sensor, the Gidrolock emergency water protection system gives an alarm signal and automatically shuts off the water supply using ball actuators.

Resumption of supply occurs only after the elimination of the accident. Gidrolock water leakage protection is a leakage prevention system that can be installed in apartments and country houses, public and administrative buildings, industrial and storage facilities, boiler houses and local heating stations, water treatment plants, in water supply and heating systems, where leakage is possible water.

However, this device has limited functionality and works only in the event of an emergency and only one engineering water supply network.

The utility model is based on the task of expanding the functionality of the system, to provide the ability to automatically turn off all available engineering networks, in particular water and / or gas, and / or electric power, and others, including during abnormal operation, as well as to monitor and prevent emergencies from all engineering networks of the room .

The system for preventing emergencies of engineering networks of rooms, which contains a control unit connected to water sensors and valves, according to a utility model, further comprises an intelligent motion sensor and / or gas sensor, and / or a humidity sensor and / or temperature sensor, and / or a fire sensor and / or a light sensor, the control unit is configured to be remotely controlled. The control unit is additionally configured to set a response coefficient depending on the time of day and with the ability to connect a control panel with operation indication and control buttons. The control unit may further comprise a Wi-Fi module, a GPS module, a radio control module. The control unit may be configured to install a backup power source and may further comprise a forced power off / on button with the ability to operate for a given interval (timer). Shutoff valves are additionally made with the possibility of manual control.

An intelligent motion sensor expands the functionality of the system for preventing emergencies of engineering networks of rooms, since it provides control of the presence of a person in the room and sends a signal to turn off engineering systems in the absence of a person. Connectivity the whole system of sensors - water and / or gas sensor, and / or humidity sensor and / or temperature sensor, and / or fire sensor, and / or light sensor - significantly expands the scope of the system, since it allows you to control all engineering systems of the premises, including including preventing emergencies. The control unit with a Wi-Fi module, GPS module, with a radio module, with a control panel with operation indication and control buttons allows you to monitor the system operation remotely. It also provides a manual shutdown mode for all engineering networks of the room with a forced shutdown / on button in the control unit. Manual control of shutoff valves allows mechanical control of engineering systems of the premises.

The drawing schematically shows a General view of the system for emergency shutdown of utility networks of premises with remote control.

The system for preventing emergencies of engineering networks of premises consists of a control unit 1 connected to an intelligent motion sensor 2, a system of sensors 3 for water leakage and / or a gas sensor, and / or a sensor for measuring other parameters (temperature, humidity, lighting, etc. ), shutoff valves 4 and connected to the power supply 5.

The control unit 1 is connected to a 220 V power supply and can contain a battery for backup power in case of a power outage, a voltage converter unit, a Wi-Fi module, a GSM module, a radio module for wireless operation with sensors 3 or other equipment, and outputs for wiring additional 3 sensors, modules, relays and blocks (not shown in the figure). The control unit 1 provides the ability to connect others, necessary because of the specific needs of the sensors 3, such as a humidity sensor, temperature sensor, fire sensor, light sensor and the like. Such additional sensors may be required due to the specifics of operation and control of other parameters in the room, such as humidity, lighting, temperature, etc. Also in the control unit 1, there are modules for delivering an alarm signal not only to the room, but also to the dispatchers, the owner on a mobile phone and programmatically via the Internet with the characteristics of the accident - which sensor worked, in what sequence, if several sensors worked, at what time and successfully whether communication is blocked.

Intelligent motion sensor 2 with zeroing the countdown time monitors the presence of movement in the room, does not send a signal to the control unit while there is movement and is monitored for a specified period of time, and if there is no movement for a certain (set) time, it signals the absence of movement movement, and therefore people at the facility, which mainly indicates the lack of need for communications. In the absence of movement for a certain period of time, a signal is sent to control unit 1, and a signal is transmitted from control unit 1 to shut off all incoming shutoff valves 4, in particular water, gas, electricity, etc.

The control unit 1 is made with power from the main AC network. The control unit 1 includes a forced disconnect / enable button, when pressed, the communications are forcedly disconnected at a predetermined interval for operation (timer) in order to give the user time to safely leave the facility before disconnecting communications.

To increase the reliability of the device in case of emergency disconnecting the main power network, the control unit 1 can accommodate a backup power source. The backup power source is a rechargeable battery, which is located in the control unit 1, which also has a power supply unit that converts an alternating voltage of 220 V to a constant voltage of 12 V, which is the working one for this unit 1, modules and sensors 3, shutoff valves 4, which are connected to unit 1 and used to recharge the backup battery.

Also, the control unit 1 may contain a Wi-Fi module for controlling the equipment of the program via the Internet both by the user and the dispatcher. It can also contain a GPS module for sending SMS messages and controlling work by exchanging commands in SMS messages.

Also, the control unit 1 provides for the connection of a control panel with an indication of operation and control buttons, which can be mounted in places remote from the control unit 1 itself.

The control unit 1 can take into account the response coefficient depending on the time of day. That is, if the interval of operation of the intelligent motion sensor 2 is set to no movement for 4 hours, then the coefficient for correction in night mode can be set at 2 times, which means that at night this interval will be 4x2 = 8 hours without movement. It is recommended to set the time for the operation of this sensor 2 to the off mode of all communications to be between 2 hours and 9 hours, but this is only the recommended time that the user can set at his own discretion. An intelligent motion sensor 2 is proposed to be installed in the place where the movement most often occurs, or a periodically guaranteed stay of a person, in particular a bathroom, is guaranteed. A sensor 3 for the presence of water (a pair of open electrodes) and / or sensors 3 for the presence of methane / propane / carbon dioxide gas, and / or a fire sensor, and / or other sensors necessary because of the specifics of monitoring other parameters in the room, such as humidity, temperature, etc. All these sensors 3 are connected and controlled by wire, or wirelessly with the control unit 1, which gives a signal to turn off the supply of water, gas or electricity to the room.

Flood sensors 3 for emergency shutdown of water supply, are blocks that are located in places of possible primary water ingress during an accident, namely under water distribution fittings, a drain tank, a washbasin, a shower or a bathtub and can be attached both to the ground and to pipes or hoses. In the case of water entering the sensors 3, a signal is sent to the control unit 1 about an accident in the water supply system and a signal is sent from the control unit 1 to the water-stop valves 4 of the water inlet and the water inlet is blocked. Similarly, the emergency gas sensor 3 is triggered, which is located at the top of the room and optionally in other places. If there is propane / butane / methane / carbon monoxide gas in the air outside the normal range, the sensor 3 sends a signal to the control unit 1, and the control unit 1 sends a signal to close the shutoff valves 4 of the communications to the room and gives an audible signal about an accident in the room, gives the command to the shutoff valves 4 to shut off the gas supply to the room and turn on the hood, if there is a connected forced hood. If necessary, you can understaff other sensors 3, in particular humidity, light, fire, etc., to meet the additional needs of the client related to the specifics of his needs.

Shut-off valves for water 4 and / or gas and / or power supply and etc. - These are blocks, modules, electric shut-off valves, electromagnetic relays and more, depending on what communications the device works with. For water, gas, it can be an electromagnetic shut-off valve, an electrically-operated valve, etc. installed on water / steam / gas folding pipelines for supplying cold, hot water, and / or steam and / or gas. For power supply - it can be an electromagnetic relay, block or module that disconnects power supply to the room. All this shutoff valves 4 are wired or wirelessly connected to the control unit 1 and are triggered to shut off the supply of communications in the event of an emergency, or to prevent the occurrence of such.

An emergency shutdown of the water supply during an abnormal mode of operation of the water supply network ensures that water-folding fittings are installed on the supply pipe, in front of which safety shutoff valves 4 are installed, made to operate in the presence of water leaks, or when the specified time is not used due to the lack of need for use, which in turn, even prevents the possibility of an emergency in general. The water supply emergency shutdown device further comprises various sensors 3, including sensors 3 for the presence of gas in the room, which is located at the top of the room where the gas equipment is available, or sensors 3 for the presence of water, each of which is made in the form of two open electrodes fixed to the floor and it is located under the corresponding water-folding fittings on the floor under the sink drain hole, washbasins, bathtub, shower, drain tank, etc., moreover, the safety shut-off valves are made in the form of normally open dug electric crane. This system provides the ability to connect other necessary sensors 3, in particular a fire sensor, humidity sensor, temperature sensor and etc. Sensors 3 and shutoff valves 4 are electrically, wired, or wirelessly connected through control unit 1, and the supply pipe is a common riser for gas or water entering the room. This shut-off valve 4 provides for manual control.

The system for preventing emergencies of engineering networks of premises works as follows.

The system is designed to operate in two main modes:

- mode of tracking the accident and avoiding the serious consequences of the accident;

- accident prevention mode.

The principle of operation of the accident tracking mode and avoiding the serious consequences of the accident.

In the operating mode of operation of the water / gas pipeline system, or the power supply system, their work is carried out in the usual way, and the shut-off valve 4 is in the open position. In the event of an emergency, which threatens flooding the room, leakage of domestic gas, carbon dioxide, smoke - water begins to fall on the floor of the room, or gas enters the room, or carbon dioxide is formed, smoke is generated. In this case, the corresponding sensor is activated, which monitors the occurrence of an emergency and sends a signal to the control unit, which will be registered by unit 1, which sends a signal to close the shutoff valves 4, which blocks the flow of water or / or / and gas, or / or / and electricity to the room and through the GSM modules, or / or / and Wi-Fi, a signal is sent to the owner, or / or / and the dispatcher to the console or to mobile devices through computer programs. As a result, the owner receives a message and provides protection of the premises from flooding by water from the water supply network, or the accumulation of gas in the room, fire, depending on which of the sensors 3 (water, gas, etc.) worked. If at the time of the accident a simultaneous shutdown of the voltage in the power supply 5 occurs, the control unit 1 and the shut-off valve 4 are closed by the backup battery power source - this ensures the highest reliability of the device for emergency shutdown of communications. If there is no backup power supply - the power supply of the control unit should be connected in front of emergency machines or a relay at the input of electricity to the room so as not to disconnect the control unit.

To prevent accidents and unnecessary communication costs, the system provides an intelligent motion sensor 2, which not only monitors the presence of movement in the room, but which enters the tracking mode during the first movement and does not turn off until there is no movement for set for tracking period of time. If the intelligent motion sensor 2 has tracked the movement during a specified monitoring period, then the countdown of the specified monitoring period starts again until the movement is completely stopped during the entire specified monitoring period and only then the intelligent motion sensor 2 sends a signal to the control unit 1 about the absence of people at the facility. Having received such a signal from an intelligent motion sensor 2, the control unit 1 gives a signal to the shutoff valve 4 to block the flow of communications. The proposed intelligent motion sensor 2 takes into account all movements at the time of tracking, without giving a signal to turn off and resets a predetermined period of time for operation after each movement, even during tracking. It is this principle of operation of the intelligent motion sensor 2 that is used in the prevention mode accident occurrence.

Using the proposed utility model can significantly increase the compactness, reliability and convenience of the emergency shutdown device for supplying water and / or gas and / or electricity during an emergency mode of operation of the network, as well as expand its functionality.

The accident prevention mode works similarly, but taking into account the absence of a person at the facility for a certain time, which may indicate that there is no need to connect all communications in the room, which means saving resources and money, avoiding the human factor when the person forgot to turn off the communications into the room and the like. A significant difference between this mode and the tracking mode of an existing accident is that the receipt of communications is disabled by the intelligent motion sensor 2 in the absence of people at the facility and the need for communications, which in turn makes it impossible for the accident to occur for the entire period of absence of people in the room.

Using the proposed utility model makes it possible to save resources by preventing leakage due to breakdowns, or the improper technical condition of equipment that consumes resources. Safe living conditions are created in multi-storey residential buildings due to a gas leak or flooding when there is no person in the apartment, a fire due to a short circuit, etc., the ability to respond in a timely manner to what is happening. Especially this system will be useful for older people who are unable, unable to use computer programs and will not be able to disconnect communications remotely, if you forgot to turn off some devices, or communications in general, and left the room for a long time.
