Description

Smart fire prevention water supply system {Smart fire prevention water supply system}

The present invention relates to a smart fire prevention water supply system. Specifically, various embodiments of the present invention relate to technology.

Forest fires in Korea vary in the number of forest fires and affected areas according to social conditions, forest conditions, forest policies, systems, and weather changes of the times. Forest fires occurred the most in April by month, and are on the rise in March and November. In addition, by day of the week, Sunday showed the highest frequency of occurrence, but with the implementation of the 5-day work week in the 2000s, Friday and Saturday also showed a rapid increase.

When looking at the statistics of forest fires as described above, most of the forest fires are artificial forest fires caused by hikers, etc., and most of them occur in places where hikers can easily access, such as hiking trails. In particular, in the case of mountain fires occurring in alpine areas, vehicle entry is almost impossible, so for initial evolution, firefighters must run to the fire site with portable firefighting equipment to extinguish the fire.

In addition, even firefighting helicopters cannot be operated at night when strong wind blows or visibility is difficult, so it is often necessary to watch the fire until the firefighting helicopter can operate. Firefighting equipment for early extinguishing is urgently needed.

As a conventional technique for solving this, there is a 'fire suppression grenade launcher' of Korean Patent Publication No. 10-2004-0083199. The fire extinguishing grenade launcher is capable of firing a fire extinguishing grenade containing a fire extinguishing liquid so that a fire can be easily extinguished from a distance when a fire occurs in an area where a fire truck or a fire helicopter cannot approach.

However, in the case of the prior art as described above, it is difficult to install and manage launchers individually in mountainous areas occupying more than half of the country.

Various embodiments of the present invention are to solve the above problems, and an object of the present invention is to provide a system that can be easily managed and quickly put into high-rise buildings or high-rise buildings when water is needed.

The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

To this end, the present invention includes a storage unit for storing the fluid, a water collector for moving and collecting the fluid, and a control unit connected to the water collector and controlling the spraying of the fluid in the water collector.

According to an embodiment of the present invention, it is possible to easily supply the fluid even at a point where it is difficult to supply the fluid, and it is possible to prevent excessive waste of resources during the supply process.

In addition, through the present invention, installation is easy and management is possible through a general portable terminal, so convenience and versatility can be maximized.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

1 is a diagram showing a smart fire prevention water supply system as a whole according to an embodiment of the present invention.

A smart fire prevention water supply system according to the present invention includes a storage unit 110 for storing fluid, a water collecting unit 120 for moving and collecting fluid, a passage part 130 connecting the storage part 110 and the water collecting part 120 to provide a fluid supply path, a vaporization part 140 connected to the passage part 130 and inducing a state change of the fluid moving from the storage part 110 to the water collecting part 120, and a passage part 13 0) and the water collecting part 120, the blowing part 151 for moving the fluid in the direction of the water collecting part 120, the power generation part 152 connected to the blowing part 151 to supply power for driving, the water collecting part 120 and controlling the injection of the fluid in the water collecting part 120. A measuring unit 170 is included.

The storage unit 110 is provided for the purpose of collecting fluid and sending it to the water collecting unit 120 . To this end, the storage unit 110 is provided as a collecting means such as a tank to store the fluid, where the state of the fluid may be provided as a liquid. In addition, the storage unit 110 may be provided with a separate water purifying unit for purifying fluid, and the fluid may be moved from the outside to the inside of the storage unit 110 and stored through a separate supply unit.

The water collector 120 is installed in a place where demand for fluid is required, and is opened when supply of fluid is required to supply the fluid. To this end, the water collecting unit 120 may be provided in the form of a water collecting well located in a high place such as a high-rise building or a mountain and capable of collecting and storing fluid, but is not limited thereto. Meanwhile, the water collecting unit 120 is connected to the control unit 160, and opening and closing proceed according to a signal from the control unit 160 generated in response to an input of a terminal unit connected to the control unit 160. In addition, the water collector 120 may be connected to the measurement unit 170 to measure the flow rate therein.

The passage part 130 connects the storage part 110 and the water collecting part 120, and provides a path through which the fluid stored in the storage part 110 moves to the water collecting part 120. To this end, the passage part 130 is provided in the form of a pipe, etc., and in the process of connecting the storage part 110 and the water collector 120 to each other, the vaporizing part 140 and the blowing part 151, which will be described later, can be connected.

The vaporizing unit 140 is provided to move the fluid in a vaporized state. In detail, the vaporization unit 140 is provided for the purpose of moving a fluid with a larger flow rate compared to the same time. To this end, the vaporizer 140 is provided with a means capable of atomizing the fluid and converting it into a vaporized state, such as a vaporizer or a carburetor. The vaporization unit 140 injects gas such as air into the interior while connected to the passage unit 130, and in response thereto, the fluid is scattered and vaporized in a spray form, and is located inside the passage unit 130. In this state, gaseous fluid may move to the collecting well by the blower 151 to be described later.

The blowing unit 151 is a component for moving gaseous fluid to a collecting well. In detail, the blowing unit 151 is provided to easily move the fluid toward a collecting well located at a higher level than the storage unit 110 . To this end, both ends of the blowing unit 151 are connected to the passage unit 130 and the collecting unit 120, respectively. The blowing unit 151 receives gaseous fluid from the passage unit 130 and moves the fluid to the collecting unit 120 through driving. The blowing unit 151 may be provided as a blowing means such as a negative pressure blower or a blower that blows air using gas pressure. As described above, since the blower 151 for moving the fluid in a gaseous state is provided, it is possible to transfer the fluid more easily and quickly compared to moving the fluid in a liquid state. In addition, a fluid that needs to be moved to a high height can be moved more easily. On the other hand, the blowing unit 151 may be driven by the control unit 160, which will be described later. In this case, the liquid in a gaseous state may be sprayed after the water collecting unit 120 is opened, and the liquefaction unit 190, which will be described later, is installed. In addition, when a plurality of mooring units 180 are provided, a plurality of blowing units 151 may be provided so as to be positioned between the plurality of mooring units 180 .

The generator 152 supplies power necessary for driving the blower 151 . Specifically, the generator 152 allows the blower 151 to use power even if it does not have a separate driving power source. To this end, the power generation unit 152 is connected to the blower unit 151 and is provided as a solar module capable of converting light energy into electrical energy and supplying it. However, the power generation unit 152 is not limited thereto and may be provided as a power generation means capable of converting and supplying various energies such as wind power, geothermal power, and tidal power into electrical energy. Through the power generation unit 152 as described above, installation and operation of the blower unit 151 can be easily induced even at a point where it is difficult to carry and install a battery, thereby maximizing convenience and versatility.

The control unit 160 controls the injection of fluid. In detail, the control unit 160 controls the opening and closing of the water collecting unit 120 for the fluid that has moved to the water collecting unit 120 through the passage 130, so that the fluid is ejected or stopped at the point where the water collecting unit 120 is located. To this end, the control unit 160 is communicatively connected to the water collecting unit 120 . Here, the communication form of the control unit 160 and the collecting unit 120 is equipped with Bluetooth, ZigBee, Wi-Fi, IOT, LPWA (Law-power wide area network), etc., but is not limited thereto. In addition, the control unit 160 may control injection and supply of fluid in response to an input of the terminal unit by being communicatively connected to the terminal unit. On the other hand, the control unit 160 may control the additional supply of fluid based on the water storage amount of the water collecting unit 120 and the plurality of mooring units 180 calculated by the measuring unit 170 to be described later. This will be described later with reference to FIG. 3 .

The measuring unit 170 is a component that measures the flow rate in the water collecting part 120 and the mooring part 180, and is provided for the purpose of grasping the current state in which fluid reaches the water collecting part 120 or is temporarily stored in the mooring part 180 in the middle. To this end, the measuring unit 170 is communicatively connected to the water collecting unit 120 and the mooring unit 180, and the communication type is provided with Bluetooth, ZigBee, Wi-Fi, IOT, LPWA (Low-power wide area network), etc., but is not limited thereto. The measurement unit 170 is connected to a separate sensor unit provided inside the mooring unit 180 and the water collecting unit 120 to obtain information on the water level, and the position where the mooring unit 180 and the water collecting unit 120 are installed. It is possible to calculate a graph of altitude based on the information on the information.

2 is a diagram showing a smart fire prevention water supply system in which a mooring unit 180 according to an embodiment of the present invention is reflected, and FIG. 3 is a mooring unit 180 calculated by a measurement unit 170 according to an embodiment of the present invention. It is a diagram showing the altitude and water storage amount of the collecting unit 120.

The mooring unit 180 is a configuration for maximizing the movement efficiency of the fluid moving to the water collecting unit 120 by the blowing unit 151, and temporarily mooring the fluid. To this end, the mooring part 180 may be disposed between the relatively low storage part 110 and the relatively high receiving part and connected to the passage part 130. Accordingly, the mooring unit 180 may collect and store the fluid moving by the blowing unit 151 in the middle. As another embodiment, the mooring unit 180 may have one side partially opened to collect naturally occurring rainwater, or may be provided in a tub shape capable of receiving fluid from a separate rainwater gutter. Through this, it is not necessary to excessively move the fluid from the storage unit 110 to the mooring unit 180, and resources such as electric energy for driving the fluid and the blowing unit 151 can be saved. In addition, since the mooring unit 180 is provided, the size of the storage unit 110 and the water collecting unit 120 can be reduced, which has a remarkable effect in terms of convenience of installation and maintenance.

3 is a graph formed by the measuring unit 170, and the horizontal axis indicates a plurality of mooring units 180 (meaning mooring unit 180 1, mooring unit 180 2 and mooring unit 180 3 in FIG.

The bar graph formed in the vertical direction of the graph relates to the water storage amount, and the flow rate of the fluid located inside the plurality of mooring units 180 and the water collecting unit 120 is measured and posted through a separate sensor unit connected to the measuring unit 170.

The polygonal line graph is information about the standard storage amount pre-stored in the control unit 160, and is provided to vary according to the altitude, and may be set differently according to external environments such as temperature and humidity at the altitude, which is connected to the control unit 160. It can also be set in the terminal unit. For example, the flow rate of the fluid to be stored in the water collector 120 may be set to be higher than that of other mooring units 180 .

Referring to FIG. 3 , the actual water storage amount of the mooring unit 180 1 is measured to be smaller than the reference storage amount corresponding to the mooring unit 180 1 . Accordingly, the control unit 160 drives the blowing unit 151 to move the fluid toward the mooring unit 180 1, or opens a separate opening/closing means so that the mooring unit 180 1 can receive rainwater generated from the outside.

On the other hand, the water storage volumes corresponding to the mooring unit 180 2 , the mooring unit 180 3 , and the water collection unit 120 are measured to be greater than the respective reference water storage volumes. Accordingly, the control unit 160 temporarily stops driving of the blowing unit 151 positioned between the mooring unit 180 2 and the mooring unit 180 3 so that fluid is not additionally supplied.

When a fluid usage event occurs, such as a fire occurring near the water collector 120, the water collector 120 is opened based on an input from a terminal unit that is communicatively connected to the control unit 160. In this process, the blowing unit 151 located between the plurality of mooring units 180 is driven to quickly move the gaseous fluid toward the collecting unit 120. Through this, the fluid can be moved to and discharged to the water collector 120 for use.

4 is a view showing a smart fire prevention water supply system in which the liquefier 190 according to an embodiment of the present invention is reflected.

Through a series of configurations described above, the gaseous fluid can be moved and discharged to the water collector 120, and the fluid is converted into a liquid immediately before discharge from the water collector 120 through the liquefier 190, so that fire can be extinguished and water can be used more conveniently.

The liquefaction unit 190 is a component for liquefying gaseous fluid moving from the passage unit 130 or the mooring unit 180 to the water collecting unit 120 . To this end, the liquefaction unit 190 is connected to the passage unit 130 and the mooring unit 180. That is, the liquefaction part 190 is located between the passage part 130 formed toward the water collecting part 120 and the water collecting part 120 while connected to the mooring part 180 . The liquefaction unit 190 supersaturates the gaseous fluid and then changes it into a condensed water type fluid through gas-liquid separation. To this end, the liquefaction unit 190 continuously induces the generation of condensed water caused by the primary flow rate reduction of the fluid by the plurality of filtering units 192 and the secondary flow rate reduction of the fluid by the condensation inducing unit 193. As a result, the state of the fluid is converted into a liquid.

5 is a view showing a liquefaction unit 190 according to an embodiment of the present invention, and FIG. 6 is a view showing a condensation induction unit 193 according to an embodiment of the present invention, in which part a of FIG. 5 is enlarged. Here, “forward” is a direction from the liquefaction unit 190 toward the storage unit 110, and is a direction opposite to the fluid supply direction. In addition, “rearward” is the opposite direction of “front” and means a direction in which fluid moves from the storage unit 110 to the collecting unit 120.

The liquefying unit 190 liquefies the fluid through the reducing unit 191, the filtering unit 192, and the condensation inducing unit 193. In detail, the liquefying unit 190 reduces the flow rate of the fluid through the reducing unit 191 and the filtering unit 192, and converts the gaseous fluid into a condensed water type fluid through the condensation inducing unit 193. To this end, the liquefaction unit 190 is provided in the form of a cylinder having a cylindrical or polygonal cross section located between the passage unit 130 and the water collecting unit 120 and has an open interior. In addition, since a pair of separate check valves (first check valve and second check valve) are located inside the liquefaction unit 190 so as to be close to the passage part 130 and the water collecting part 120, respectively, it is possible to prevent unintentional reverse flow and outflow of the fluid located inside the liquefaction unit 190.

The reduction unit 191 induces a first decrease in flow rate. The reducing portion 191 is provided at a portion where the diameter of the inner circumferential surface of the liquefying portion 190 gradually increases, and is provided in a funnel shape, but has a shape in which the size of the internal space gradually increases. Accordingly, the flow rate of the fluid introduced into the liquefaction unit 190 through the separate check valve (first check valve) located at the front end of the liquefaction unit 190 is reduced as the pipe diameter is enlarged.

The filtering unit 192 is provided to induce a secondary flow rate decrease for the fluid having a primary flow rate decrease. To this end, the filtering part 192 is located behind the reducing part 191 and has one or more air gaps. In the course of the fluid passing through the filtration unit 192 through the air gap, a secondary reduction in flow rate occurs. As another embodiment of the present invention, a plurality of filtering units 192 may be provided to maximize a deceleration effect. In detail, the plurality of filtering units 192 are arranged in a line along the front and rear sides of the liquefying unit 190, but may be provided so that the size of the gap decreases from the front to the rear. That is, the size of the air gap of the filtering unit 192 located at the front is larger than that of the filtering unit 192 located at the rear. This is to maximize the effect of reducing the flow rate of the fluid sequentially passing through the filtering unit 192 through the air gap. As described above, through the plurality of filtering units 192 spaced apart along the moving direction of the fluid to further reduce the speed of the fluid, it is possible to significantly lower the flow rate of the fast-flowing gaseous fluid, so that liquefaction is easy.

The condensation induction unit 193 is a component for converting a fluid in a gaseous state into a fluid in the form of condensation water. To this end, the condensation inducing unit 193 is located between the plurality of filtering units 192 . In detail, the condensation induction unit 193 is formed intaglio in a spiral arrangement on the inner surface of the liquefaction unit 190, and forms a liquid fluid. Specifically, the condensation induction unit 193 is provided in a form that is etched on the inner circumferential surface of the liquefying unit 190, but the shape is formed in a comb pattern or a three-dimensional spiral shape. Accordingly, the fluid passing through the plurality of filtering units 192 performs spiral rotation like a vortex around the central axis of the liquefying unit 190 while being in contact with the condensation inducing unit 193 between the filtering units 192 . In this process, collision inertia of the fluid occurs in the condensation inducing unit 193 located between the plurality of filtering units 192 due to a difference in flow velocity of the fluid passing through each of the plurality of filtering units 192 . That is, condensed water is generated due to the spiral rotation caused by the condensation inducing unit 193 in a space (between the plurality of filtering units 192) where the flow velocity reduction of the fluid is sequentially applied. This method is repeated, and the fluid is liquefied and moved to and stored in the water collector 120 . On the other hand, as another embodiment of the present invention, in order to induce the generation of condensed water, a method of generating electric potential or electrolysis for a fluid may be used.

By having a configuration for liquefying the fluid as described above, in order to move to a high altitude area, the movement is carried out in a gaseous state that is easier to move, and the liquid phase can be converted immediately before use or storage of the fluid, so the transport and storage efficiency can be significantly increased.

7 is a view showing rotation of the filtering unit 192 according to an embodiment of the present invention.

The ultrasonic generator 200 is provided for the purpose of removing foreign substances from the inside of the liquefier 190 . In detail, the ultrasonic generator 200 is for cleaning the plurality of filtering units 192, and separates and removes foreign substances from the filtering unit 192 by generating ultrasonic waves in a state located inside the liquefying unit 190. The ultrasonic generator 200 may be connected to the above-described control unit 160 and a communication means such as IOT, or driven through a separate control module. Accordingly, the ultrasonic generator 200 waits in an undriven state inside the initial liquefaction unit 190 when no signal is generated according to the input of the terminal unit connected to the control unit 160. Thereafter, the control unit 160 instructs the ultrasonic generator 200 to drive according to the input of the terminal unit, and the ultrasonic generator 200 generates ultrasonic waves in response thereto.

Both ends of the filtering unit 192 are coupled to a separate rotational shaft s connected to the inner circumferential surface of the liquefying unit 190 . The rotating shaft (s) is provided to be orthogonal to the central axis of the liquefying unit 190, is provided in the form of a rod and is provided through the filtering unit 192. Here, the rotating shaft s is driven to rotate through a separate driving means connected to the liquefier 190, so that the existing front and rearward facing surfaces of the filtering unit 192 rotating around the rotating shaft s are clockwise or counterclockwise, respectively. It can be rotated 90 degrees.

In a state in which the front and rear surfaces of the filtering unit 192 are rotated so as to be orthogonal to the front and rear surfaces of the liquefying unit 190, foreign substances attached to the filtering unit 192 can be removed by inserting and driving the ultrasonic generator 200 described above. Through this, it is possible to prevent the performance of the filtering unit 192 from deteriorating in relation to the flow rate reduction.

Steps of a method or algorithm described in connection with an embodiment of the present invention may be implemented directly in hardware, implemented in a software module executed by hardware, or implemented by a combination thereof. A software module may reside in random access memory (RAM), read only memory (ROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), flash memory, a hard disk, a removable disk, a CD-ROM, or any other form of computer-readable recording medium well known in the art.

In the above, the embodiments of the present invention have been described with reference to the accompanying drawings, but those skilled in the art to which the present invention pertains may be embodied in other specific forms without changing the technical spirit or essential features of the present invention. It will be appreciated. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
