Description

[0002] SPRINKLER SYSTEM BY ADDRESS SPRINKLER HEAD [0003]

The present invention relates to a sprinkler system using an address-type sprinkler head. In the case of fire, when an extinguishing water is discharged from an address-type sprinkler head, the address-type sprinkler head generates a position signal, And a sprinkler system using an address type sprinkler head.

Fire regulations require that sprinkler systems be installed on buildings of a certain size or larger, so that early evolution occurs when a fire occurs.

A sprinkler head included in a typical sprinkler system is configured to discharge water when the temperature of the heat-sensing means rises above a predetermined temperature due to heat generated by a fire.

The sprinkler system is provided with means for detecting the occurrence of fire by detecting the discharge of the digested water, such as a flow detection device. However, since it is common that a partition for partitioning the space is installed inside the building, it is difficult to grasp the exact position where the fire occurred. The higher the building or the larger the area, the more time it takes to identify the location of the fire, which may increase the probability of failure of early evolution.

In order to solve such a problem, a fire alarm system equipped with a fire alarm for detecting heat and smoke caused by a fire is installed. However, it is often not necessary to install a fire alarm system depending on the size of the building. , There are many cases where only a sprinkler system is installed.

Therefore, a lot of research and development has been carried out in order to identify the location of a fire with the sprinkler system alone. As a part of this, a method of providing a function of a fire detector to a sprinkler head has been proposed. However, And there is a disadvantage in that electric wires are installed along the piping of the sprinkler system and electrical connection is made to each of the plurality of sprinkler heads one by one.

In order to cope with such shortcomings, a sprinkler head capable of informing a location where a fire has occurred without using electric power is disclosed in Korean Utility Model Registration Utility Bulletin No. 20-0357404 (hereinafter referred to as "Prior Art 1").

The prior art document 1 is configured to generate an alarm sound while rotating the rotary dial using the force of the digestive fluid discharged from the sprinkler head.

However, in the prior art 1, since the energy for rotating the rotary shaft is configured to be obtained from the discharge power of the digestive juice, the range of dispersion of the digestive juice around the sprinkler head is reduced, and when a fire occurs in a space without occupant There is a high possibility that the alarm sound is not transmitted to the manager of the building.

The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated and described in the drawings. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a sprinkler system 1 using an address type sprinkler head according to an embodiment of the present invention.

Referring to FIG. 1, a sprinkler system 1 using an address type sprinkler head according to an embodiment of the present invention includes a water pipe 10, a branch pipe 11, a test pipe 12, a water tank 20, The water tank 21, the sprinkler pump 30, the pressure pump 40, the pressure chamber 50, the pressure switch 60, the water flow detection device 70, the monitoring means 80, the display 81, 82 and an address-type sprinkler head 100 are included.

When a fire occurs in a building in which the sprinkler system 1 using the address type sprinkler head is installed, when the thermal means (140 in Fig. 2) provided in the address-type sprinkler head 100 is heated to a predetermined temperature or more by the flame The initial evolution is performed by allowing the digester water to be released through the watertight opening formed in the address-type sprinkler head 100.

To this end, a branch pipe 11 connected to a water supply pipe 10 is distributed and arranged on a ceiling surface or side wall of a building, and a plurality of address type sprinkler heads 100 are installed in the branch pipes 11.

A water pipe (20) is connected to the water pipe (10). The water is stored in the water tank 20. Although not shown, a water tank may be connected to the water tank 20 to store a predetermined amount of water.

When the sprinkler system (1) using the address type sprinkler head is installed in a place where the wet piping system and a part or more of the sprinkler head is not heated, antifreeze can be added to the digested water to prevent the frozen water. The components thereof may be changed.

The sprinkler pump 30 installed in the water supply pipe 10 is for flowing the digested water stored in the digestive water tank 20 to the water supply pipe 10 connected to the sprinkler pump 30 when a fire occurs.

The pipe branching to the water supply pipe 10 is provided with an overpressure pump 40 to which the pressure chamber 50 and the pressure switch 60 are connected. The water supply pipe (10) is provided with a water detection device (70) for sensing the flow of the water. It is possible to determine whether or not the fire extinguishing water is discharged from the address type sprinkler head 100 by detecting the flow of the water-repellent water by the water flow detection device 70, thereby indirectly recognizing that the fire has occurred.

However, in order to be able to detect that the digestion water has been discharged from the address-type sprinkler head 100 before the sprinkler pump 30 is operated, it is necessary to keep the pressure of the digestion water in the water supply pipe 10 higher than the atmospheric pressure.

To this end, a branch pipe is formed in the water supply pipe 10, and an impulse pump 40 is installed thereon. A pressure chamber 50 and a pressure switch 60 are installed in the branch pipe.

Here, the pressure chamber 50 and the pressure switch 60 are installed in accordance with the rules of the 'fire fighting technology standard' in the domestic fire fighting regulations, and are separately provided for the filling in the water supply pipe 10 separately from the sprinkler pump 30 A dedicated automatic operation impression pump 30 is installed. At least two pressure switches (60) must be mounted in the pressure chamber (30) for automatic operation of the sprinkler pump (30) and the pressure pump (48).

Accordingly, when the fire extinguishing water is discharged from the address type sprinkler head 100 due to fire, the pressure switch 60 senses a pressure drop in the water supply pipe 10 to operate the sprinkler pump 30, To be supplied to the water supply pipe (10).

However, in the case of a high-rise building, it may be difficult to supply the fire extinguishing water to the high-level with sufficient pressure only by the sprinkler pump 30. Therefore, the high-priced water tank 21 It is possible to supply the digester water at a sufficient pressure by using the digested water stored in the digester.

The test pipe 12 is constructed such that the address type sprinkler head 100 hydraulically most remote in the piping system including the water supply pipe 10 is installed according to the rule of the ' And the test pipe 12 is provided at the end of the extended pipe to periodically test whether the water detection device 70 is in a steady state or not.

As described above, the sprinkler system 1 using the address type sprinkler head according to an embodiment of the present invention is a wet piping system. In this embodiment, ) Can also be applied to other types of sprinkler systems, such as dry piping systems or ready-operated systems.

To this end, in the present embodiment (1), in addition to the above-mentioned functions, when the digestive water is discharged from the address-type sprinkler head 100, a previously stored position signal is emitted wirelessly, and the monitoring means 80, Type sprinkler head 100 to which the extinguished water is discharged.

Therefore, in the embodiment (1), it is easy to grasp that the fire has occurred at the position where the address type sprinkler head 100 which is emitting the digestive water is installed, so that the subsequent evolution work can be performed quickly.

An address-type sprinkler head 100 having such an action and effect will be described with reference to Figs. 2 to 7. Fig.

For reference, the monitoring means 80 includes a receiving antenna 82 for receiving a position signal emitted by the address-type sprinkler head 100 and a receiving antenna 82 for receiving the position signal from the sprinkler head 100 And a display 81 for displaying a position by a picture, a symbol, or a character.

Fig. 2 is an exploded perspective view of the address-type sprinkler head 100 shown in Fig. 1, and Fig. 3 is a longitudinal sectional view of the address-type sprinkler head 100 shown in Fig.

2 and 3, the address type sprinkler head 100 includes a head body 110, a fastening member 120, a closure member 130, a direct thermal means 140, a first sensing means 150, 2 sensing means 160, a circuit box 170 and a deflector 180.

A coupling part 111 is formed at one side of the head main body 110 so as to be coupled to a branch tube 11 connected to the water supply pipe 10. A waterproofing hole 112 is formed at one side of the head body 110 to discharge the water from the branch pipe 11 in the other direction.

A support socket 114 having a support groove 115 and a coupling groove 116 is formed on the other side of the head body 110. The support groove 115 is formed in a shape corresponding to the other end of the heat sensing unit 140 to be described below and a female screw corresponding to the fastening member 120 described below is formed on the inner circumferential surface of the fastening groove 116 .

The head body 110 is formed with a support arm 113 connecting the coupling part 111 and the support socket 114. At this time, the support arm 113 is formed so that the waterproofing hole 112 can be exposed as much as possible so that the digestion water can be easily discharged through the waterproofing hole 112.

The sealing member 130 is a member that covers the waterproofing hole 112 so as to seal the fireproof water so that the water is not discharged through the waterproofing hole 112. The sealing member 130 is provided with a supporting groove 130 corresponding to one end of the heat sensing unit 140 131 may be formed.

One end of the heat sensing unit 140 is inserted into the support groove 131 of the closure member 130 to support the closure member 130 to cover the waterproof hole 112 and the other end thereof is connected to the support socket 114 So that the state in which the thermal head 140 supports the sealing member 130 by the support sockets 114 is maintained.

For reference, the thermal sensor 140 may be made of a glass or quartz bulb in which a liquid whose volume is expanded according to a rise in temperature is sealed inside. Therefore, when the temperature of the heat sensing means 140 rises above a predetermined temperature, the bulb ruptures and the support of the sealing member 130 can be released.

When the sealing member 130 is released from the thermal conductive member 140 by the fire extinguishing water pressure in the branch pipe 11, the sealing member 130 is released from the waterproof opening 112, Digestion water is released.

Meanwhile, although not shown, the thermosyper 140 may be made of a material such as lead or tin, which is melted at a relatively low temperature, to support the sealing member 130 at normal times and then heated to a predetermined temperature So that the support of the sealing member 130 is released while the alloy is melted or deformed.

As shown in the figure, the first sensing means 150 is fixed at one end to the support arm 113 and at the other end in contact with the heat sensing means 140. At this time, the first sensing unit 150 may be installed such that the other end of the first sensing unit 150 is directed toward the other side of the head body 110 and the middle portion of the first sensing unit 150 is resiliently deformed convexly toward one direction of the head body 110 have.

This is to prevent the first sensing means 150 from being arbitrarily vibrated due to wind or collision with other objects around the addressable sprinkler head 100. The first sensing means 150 is provided with a water- So that the malfunction of the embodiment (1) is prevented.

Fig. 5 is an enlarged view of a portion indicated by V in Fig. 3, and Fig. 6 is an enlarged view of a portion indicated by VI in Fig.

Referring to FIG. 6, the first sensing unit 150 includes an elastic strap 151, a first piezoelectric body 153, and a first electrode layer 154. For reference, only one first sensing unit 150 may be installed, and another first sensing unit 150a may be installed as shown in FIG.

Since the first sensing means 150 and 150a have the same configuration and operation effect, the first sensing means 150 and 150a will be described with reference to the first sensing means 150 and 150a.

The elastic strap 151 is a plate-shaped member having electrical conductivity and elasticity, and a thin plate made of brass or stainless steel may be used.

A first piezoelectric layer 153 may be laminated on one surface of the elastic strap 151 and a first electrode layer 154 may be laminated on the first piezoelectric layer 153. The first piezoelectric layer 153 may be formed of a piezoelectric ceramic such as Pb (Zr, Ti) O _3, and the first electrode layer 154 may be formed of a layer of Ag by vapor deposition. The first piezoelectric layer 153 and the first electrode layer 154 may be replaced with commercially available piezoelectric films (PVDF).

Piezoelectric ceramics is a material in which a piezoelectric phenomenon occurs, and a piezoelectric phenomenon refers to a phenomenon in which a mechanical external force is applied and mechanical energy is converted into electric energy when the shape is deformed. Accordingly, when the elastic strap 151 is deformed, the first piezoelectric body 153 is deformed together, and a current is generated between the elastic strap 151 and the first electrode layer 154.

Although not shown, conductors are connected to the elastic strap 151 and the first electrode layer 154, respectively, and these conductors are electrically connected to the transmitting means provided in the circuit box 170 described below. Accordingly, when the first sensing means 150 is deformed, the generated power is applied to the transmitting means.

For reference, although not shown, the first piezoelectric layer 153 and the first electrode layer 154 may be bonded to the other surface of the elastic strap 151 or may be bonded to both surfaces. The amount of power generated in the mechanical deformation of the elastic straps 151 can be increased.

On the other hand, when the support arm 113 has electrical conductivity, one end of the elastic strap 151 is coupled to the support arm 113 so as to be electrically insulated.

5 shows a state in which the digester water is discharged through the water discharge opening 112 as the thermal insulating means 140 is ruptured and the sealing member 130 is released from support.

When the other end of the first sensing means 150 is supported by the heat sensing means 140 and is discharged through the water discharge opening 112 of the extinguished water, a flow WF of extinguishing water is generated. At this time, an elastic force acts on the end of the first sensing means 150 in the direction in which the thermosensitive element 140 is located due to the elasticity of the elastic strap 151, while the other end of the first sensing means 150 is water- Force is applied in the opposite direction of the elastic force by the force F1 generated by the flow WF.

Therefore, the first sensing means 150 vibrates repeatedly the deformation and the restoration as shown by the double arrows in Fig. As a result, the first piezoelectric body 153 continuously undergoes mechanical deformation, and therefore electric power is continuously generated in the first piezoelectric body 153.

In order to further amplify the vibration of the first sensing means 150, an inclined barb 152 is formed at the other end of the elastic strap 151.

Fig. 4 is an enlarged view of a portion indicated by IV in Fig.

Referring to FIGS. 4 and 5 together, an inclined barb 152a is formed at an end of the elastic strap 151a. Here, since the elastic strap 151a has the same action and effect as the elastic strap 151 described above, the overlapping description will be omitted.

The inclined barb 152a is formed to form an angle? With respect to the thickness direction of the elastic strap 151a. Here, the thickness direction of the elastic strap 151a is parallel to the direction (F1 direction in Fig. 5) in which the digestive effluent is discharged from the waterproof port 112. [

The above-described range of the angle [theta] is determined in the range between the direction in which the extinguishing water is discharged and the direction perpendicular to the direction in which the extinguishing water is discharged.

For reference, the warp barb 152a may be formed by cutting a portion of the elastic strap 151a as shown in the figure, or by forming the warp barb 152a separately (not shown) so as to be fixedly attached to the end of the elastic strap 151a .

When the end of the first sensing means 150 is brought into contact with the flow FW of the digestive water by the inclined barb 152a, the force due to the flow FW of the digestive water acts on the inclined barb 152a, The force acting on the support member 152a includes a component in the lateral direction.

Therefore, a torsional stress is applied to the elastic strap 151 by the force in the lateral direction of the force in the F1 direction. When the width of the elastic strap 151 is sufficiently narrow, the first piezoelectric element 153 also undergoes a twist deformation A large amount of electric power can be generated. At the same time, the vibration direction of the elastic strap 151 also slightly forms an angle with respect to the F1 direction, so that the vibration displacement of the elastic strap 151 is increased, and more power can be generated.

Therefore, when the fire extinguishing water is discharged through the water discharging opening 112, power can be continuously applied to the transmitting means by the continuous vibration of the first sensing means 150, 150a as described above.

The deflector 180 is dispersed around the deflector 180 when the fire extinguishing water is discharged through the watertight opening 112, so that the fire extinguishing water can be scattered to a maximum extent. Alternatively, a deflector 180 having a different shape than shown may be used to allow the extinguishing water to be dispersed in a particular direction.

The sprinkler head 100 of the address type has a top-down type deflector 180 mounted on the branch tube 11 such that the deflector 180 is disposed below the head main body 110, A side wall type in which the branch pipe 11 is installed on the side wall of the building and the fire extinguishing water is dispersed in the opposite direction of the side wall.

The shape of the deflector 180 is different because the direction of discharge of the extinguishing water is different according to the bottom-up, top-down, and side wall equations. Thus, the addressable sprinkler head 100 included in the present embodiment (1) is configured such that the deflector 180 is detachably coupled to the support socket 114 by the fastening member 120, The deflector 180 having a shape suitable for the position where the head body 110 is installed can be selected and coupled to the head body 110.

Therefore, the manufacturer who manufactures the address type sprinkler head 100 can manufacture the address type sprinkler head 100 by securing only a proper amount of deflector of a suitable shape according to the installation style of the address type sprinkler head 100, It is possible to obtain an effect of reducing the amount of stock and the amount of parts to be held in advance.

If the existing method of applying the address type sprinkler head 100 is changed in advance, a suitable deflector 180 can be selected and combined at the installation site according to the installation method of the address-type sprinkler head 100, Can be further improved.

In addition, the address type sprinkler head 100 can be further classified into a flush type and a convosh type according to the installation method.

Most of the head body 110 is flush-type (terminology based on domestic test standards), and most of the head body 110 is hidden in an interior material (half size) covering the ceiling surface, It refers to being installed in a mold.

The contours of the sprinkler head (100) are covered by the cover plate and the entirety of the sprinkler head (100) is embedded in the half-shell so that there is no protruding portion below the half-shell. Accordingly, the appearance is very good and damage due to collision is prevented during indoor work such as transportation of furniture. For reference, the cover plate is made of fuse metal, and when the temperature is reached, the cover plate is detached and installed so that the addressable sprinkler head 100 is exposed.

The flush type or the confused type described above is also the same in the operation mode in which the waterproof opening is opened by the direct thermal means 140, so that the embodiment (1) may not depend on the installation method of the address type sprinkler head 100 .

Fig. 7 is an enlarged view of a portion indicated by VII in Fig. 3, and Fig. 8 is an enlarged view of a portion indicated by VIII in Fig.

Referring to FIGS. 2, 3 and 7 together, the second sensing means 160 includes a fixing portion 161 and a sensing arm 163.

The fixing portion 161 is made of an electrical insulator (non-conductive) and has a disk shape, and a through hole 162 through which the male thread portion of the fastening member 120 passes is formed at an intermediate portion thereof.

The sensing arm 163 protrudes radially from the edge of the fixing portion 161 and the middle portion of the sensing arm 163 has an arch shape protruding toward the waterproofing hole 112. The sensing arm 163 is made of a material having elasticity and electrical conductivity similar to the above-described elastic straps.

The fixing portion 161 of the second sensing means 160 is fixedly coupled to the other end of the supporting socket 114 formed at the other end of the head body 110. When the deflector 180 is coupled The fixing portion 161 is disposed in a shape interposed between the supporting socket 114 and the deflector 180. [

Referring to FIG. 8, a second piezoelectric body 165 is stacked on one surface of the sensing arm 163, and a second electrode layer 166 is stacked on the second piezoelectric body.

The second piezoelectric layer 165 is made of the same material as the first piezoelectric layer 153 described above and has the same function and effect. The second electrode layer 166 is made of the same material as the first electrode layer 154, Therefore, redundant description will be omitted.

Accordingly, in the process of the water being discharged from the waterproof opening 112 and flowing toward the deflector 180, the force F2 due to the flow of the water extinguished is applied to the sensing arm 163. This force F2 causes the sensing arm 163 to be deformed in the direction of the double-headed arrow shown in Fig. 7 and to be vibrated to be restored by the elastic force of the sensing arm 163. [

Because the digested water discharged from the waterproof opening 112 is dispersed by the supporting socket 114 and a part of the supporting arm 113 connected thereto and flows in turbulent flow, the flow of the digested water applied to the sensing arm 163 The magnitude of the force F2 caused by the force F2 is not constant.

Therefore, since the sensing arm 163 continuously vibrates by this force F2, power is continuously generated in the second piezoelectric body 165. [ At this time, since the plurality of sensing arms 163 are plural, they all generate electric power by the vibration as described above, and this electric power is applied to the transmitting means by the lead wire connected to the sensing arm 163 and the second piezoelectric body 165, respectively.

On the other hand, a rounded portion 164 is formed at the end of the sensing arm 163 as shown in FIG. The rounding portion 164 is a portion having a convexly curved surface toward the deflector 180. The end of the sensing arm 163 is connected to the deflector 180 by the force F2 applied by the sensing arm 163 by the extinguishing water. And the end of the sensing arm 163 rubs against one surface of the deflector 180 due to the vibration of the sensing arm 163 described above.

In this process, the rounding part 164 reduces the frictional force between the end of the sensing arm 163 and the deflector 180 so that the vibration of the sensing arm 163 can be smoothly performed.

An unillustrated calling means is installed in the circuit box 170. The circuit box 170 may be coupled to the head body 110 as shown in FIG.

Although not shown, the transmitting means includes a rectifying circuit, a static pressure circuit, a read only memory (ROM), a processor, and an originating antenna.

A diode and a condenser are provided in the rectifying circuit so that the electric power applied from the first sensing means 150 and the second sensing means 160 is a direct current and the flow of current is smooth.

The static voltage circuit allows the power through the rectifier circuit to have a constant voltage suitable for driving the processor.

In the ROM, a unique identification code is stored for each address type sprinkler head 100. When power is supplied to the processor, the identification code stored in the ROM is transmitted through the transmission antenna.

When the identification code is received by the reception antenna 82 shown in FIG. 1, it is possible to identify which of the plurality of address type sprinkler heads 100, so that the identification code transmitted through the originating antenna can be utilized as a position signal .

For this purpose, when the address type sprinkler head 100 is installed in the branch tube 11, it is pre-inputted to the monitoring means 80 in which position the identification code is installed.

The number and location of the reception antennas 82 can be adjusted according to the number of the addressable sprinkler heads 100 included in the embodiment 1 and the distribution area thereof, .

For reference, in the circuit box 170, a heat insulating material may be charged to prevent damage of the transmitting means by heat when a fire occurs. As the heat insulating material, materials excellent in heat insulation such as an airgel (earogel) may be used.

On the other hand, the originating circuit can generate the above-mentioned position signal only when the state in which the power generated from the first sensing means 150 and the power generated from the second sensing means 160 are simultaneously applied for a predetermined time or longer .

This is because when equipment such as a ladder or the like used for air flow due to cooling and heating or the like is contacted with the branch pipe 11 or the address type sprinkler head 100 when the fire is not generated or when the deflector 180 is replaced To prevent the monitoring means (80) from being recognized as a position signal even when the first sensing means (150) or the second sensing means (160) vibrates individually.

As a result, it is possible to prevent unnecessary inspection work from being performed in the case of non-fire.

However, in the case where the first sensing means 150 or the second sensing means 160 continuously vibrates individually, the address type sprinkler head 100 may need to be inspected.

Therefore, in addition to the above-mentioned identification code, the above-mentioned ROM further stores a delimiter code for distinguishing the case where power is applied from the first sensing means 150 and the case where power is supplied from the second sensing means 160, When the power is applied from the first sensing means 150 or the second sensing means 160 for a predetermined time, the processor causes the identification code of the addressable sprinkler head 100 to be sent along with the identification code can do.

Accordingly, it is possible to distinguish whether a fire occurs in a location where the specific address type sprinkler head 100 is installed on the display 81 or whether an address type sprinkler head 100 needs to be inspected.

For reference, the identification code may be a serial number assigned to a product by a manufacturer such as a code according to the address type sprinkler head 100, a manufacturer code, a manufacturing date, a production line number, and the like.
