Firefighting pipe connection device 100 according to an embodiment of the present invention may be a device capable of firmly coupling a plurality of pipes (eg, expansion pipes and branch pipes) provided to suppress or prevent a fire.

In the following, with reference to FIGS. 1 to 3, the structure of the fire piping connection device 100 according to an embodiment of the present invention will be described in detail.

Firefighting pipe connection device 100 according to an embodiment of the present invention is a device for connecting an extension pipe 10 coupled to a sprinkler head and a branch pipe 20 into which firefighting water flows, and extends in one direction and has an inside The penetrating body part 110, the first connection part 120 fixed to one end of the body part 110 and connectable to the expansion pipe 10, coupled to the other end of the body part 110 movably along one direction and branched The second connection part 130 connectable to the pipe, coupled to the body part 110, and at least a part of the connection part where the second connection part 130 and the branch pipe 20 are connected (ie, the end of the second connection part 130) ) is disposed at the lower part and the upper part is open, and the collection part 140 having the collection space 142a is coupled to the collection part 140 to collect the fire water leaking from the connection part, and the fire water leaking from the connection part It may include an alarm unit 150 driven by the alarm unit 150 to notify whether firefighting water is leaked. In addition, the fire piping connection device 100 further includes an operating unit 160 connected to the second connection unit 130 to move the second connection unit 130 forward and backward by rotating the second connection unit 130. can do.

The body portion 110 is provided in a cylindrical shape extending in one direction, and its central portion may pass through in one direction. In the body part 110, the first connection part 120 can be rotatably coupled to one end (based on one direction), and the second connection part 130 can be rotated and slidably moved along one direction at the other end. can be combined In addition, a collection unit 140 to be described later may be rotatably coupled to a central portion of an outer surface of the body portion 110 . Here, the body portion 110 may have a groove recessed inward along the circumference at its center, and a coupling bar 141 of the collection portion 140 described later may be rotatably inserted and coupled into the above-described groove. there is.

In addition, the body portion 110 may be formed by bending one end and the other end outward along a radial direction. Here, the radial direction may be a direction along the radius of a circle having one direction as a central axis. Meanwhile, as shown in FIG. 1 , the radial direction may include an up-and-down direction vertically orthogonal to one direction and a cross direction horizontally orthogonal to one direction.

The bent portion of the body portion 110 is supported by the first connection portion 120 and the second connection portion 130 to be described later, and the first connection portion 120 and the second connection portion 130 are separated from the body portion 110. can prevent it from happening.

In addition, the body portion 110 may include an elastic body 111 that is stretchable and contractible in one direction so as to press the second connection portion 130 . The elastic body 111 is disposed to surround the outer circumferential surface of the body portion 110, one end thereof is supported by the coupling bar 141 of the collection portion 140 coupled to the body portion 110, and the other end thereof is supported by the second connection portion. (130). Accordingly, the elastic body 111 is stretched in one direction, and the second connection part 130 may be pressed toward the other end of the body part 110 .

On the other hand, the body portion 110 may further include a regulator (not shown) to adjust the flow rate of fire-fighting water passing therethrough. That is, the regulator can control the supply amount of firefighting water supplied from the branch pipe 20 to the expansion pipe 10. The controller may include a plurality of adjusting members, a driving member, and a control member.

A fire extinguishing water control unit (not shown) of the plurality of control members may be moved to a penetrating portion (ie, an internal passage) of the body 110 . The plurality of adjusting members are disposed along the circumference of the inner circumferential surface (ie, the inner passage) of the body portion 110, overlap each other, and are movable to the center portion of the body portion 110 (ie, the center portion of the inner passage). It may be installed on the inner circumferential surface of (110).

For example, the adjusting member may be formed in a plate shape. Here, some of the plurality of adjusting members may overlap each other. The adjusting members are arranged at an even angle based on the center of the movement direction of the fire-fighting water (ie, one direction) in the inner passage, and are installed in a direction perpendicular to the movement direction of the fire-fighting water. For example, one side of each adjusting member is rotatably supported by a rotating shaft installed on the inner circumferential surface of the body portion 110, rotates, and can be deployed perpendicularly to the moving direction of the fire extinguishing water.

On the other hand, the other side of each of the adjusting members may be installed such that a portion overlaps with each other. The part where each adjusting member overlaps is a part that controls the flow rate of fire-fighting water passing through the inner passage. That is, when adjusting the flow rate of the fire-fighting water moving through the internal passage, each of the adjusting members may rotate so that the overlapping portion of the adjusting members increases or decreases at a uniform rate. That is, the adjusting member can uniformly increase or decrease the opening ratio of the inner passage to control the flow rate of fire-fighting water in the inner passage. The flow rate control method of the adjusting member is a method generally applied to a diaphragm driving method for adjusting the amount of light exposure of a camera, and the aperture ratio of the internal passage can be increased or decreased at a constant rate.

The driving member is connected to the adjusting member so as to move the adjusting member. For example, the driving member may include a rotating body, a motor, first teeth, second teeth, and third teeth. The rotating body may be rotatably installed along the inner circumferential surface of the body portion 110 . The center of the rotating body is open to allow fire extinguishing water to pass through, and the open center area is disposed in the inner passage to correspond to the moving direction of fire extinguishing water.

The rotating body may receive a driving force from the motor through the first teeth and the second teeth. A predetermined screw thread is formed on the outer circumferential surface of the rotating body. The thread meshes with the thread formed on the second teeth. Therefore, when the second gear rotates, the rotating body can rotate. At this time, the first sawtooth is provided on the central axis of the motor and can be directly rotated by the motor. Accordingly, the first sawtooth, the second sawtooth, and the rotating body may engage with each other and rotate.

In addition, a predetermined screw thread is formed on the inner circumferential surface of the rotating body. The thread meshes with the thread formed on the third teeth. Accordingly, the third tooth is rotated by the rotation of the rotating body. That is, the rotation of the first rotating body causes the third tooth to rotate inside the rotating body.

A plurality of third teeth are installed along the inner wall of the rotating body to correspond to the adjusting members. Each of the third teeth is installed at an even angle with respect to the center of the moving direction of the fire-fighting water in the inner passage. The third tooth is installed on the rotating shaft installed on the inner circumferential surface of the body portion 110 . Each rotation shaft is installed perpendicular to the rotation center of the third tooth. Accordingly, each of the adjusting members can be moved toward the inner passage by rotation of the rotating shafts. However, a method in which the driving member drives the control members is not limited thereto and may vary.

The control member may control the driving member by detecting the flow rate of fire extinguishing water passing through the through portion of the body 110 (ie, the inner passage). For example, the control unit stores a preset flow rate value, and when the flow rate value of firefighting water passing through the internal passage exceeds the aforementioned preset flow rate value, the driving member is operated to change the inner diameter of the internal passage through which the firefighting water moves. can be reduced Accordingly, it is possible to prevent a gap between the expansion and contraction pipe 10 and the first connection part 120 from being excessively introduced into the expansion and contraction pipe 10 through the control member and the pressure thereof.

The first connection part 120 is rotatably coupled to one end of the body part 110, and its central portion may pass through. For example, the first connection part 120 may be formed in a ring shape. The other end of the first connection portion 120 adjacent to the body portion 110 may be bent inward in one direction. An inwardly bent portion of the first connection portion 120 may be supported by an outwardly bent portion of the body portion 110 described above. A screw thread may be formed on the inner circumferential surface of the first connection part 120 . Thus, in a state where the first connection part 120 is supported by the body part 110, it may be screwed to the expansion pipe. For example, the first connection part 120 may be provided with nuts having different inner diameters.

Meanwhile, the first connection part 120 may include a sealing body 121 . The sealing body 121 may be disposed between the inner side of the first connection part 120 and the outer side of the body 110 . The sealing body 121 may block a gap between the first connection part 120 and one end of the body part 110 . Here, the sealing body 121 may be made of a water expansion resistant material that can expand when exposed to moisture. In general, the water expansion support material may be a material that gradually expands when contact with water using modified rubber as a main raw material. Accordingly, when a gap occurs between the first connection portion 120 and the body portion 110 and firefighting water leaks, the sealing body 121 expands due to the firefighting water in contact with the firefighting water, thereby sealing the leaking waterway.

Referring to FIG. 3 , the second connection part 130 is coupled to the other end of the body part 110 so as to rotate and move in one direction, and can be connected to the branch pipe 20 . That is, the second connection part 130 may connect the body part 110 to the branch pipe 20 . More specifically, the second connecting portion 130 may include a connecting body 131 , a sealing body 132 , a connecting rib 133 and a first gear tooth 134 .

The connection body 131 has its inside penetrated along one direction, and one end thereof may be bent inward so that the diameter of one end is shorter than the diameter of the other end in one direction. Accordingly, the connection body 131 can be supported by being caught on the other end bent outward from the body portion 110 described above, and separation of the connection body 131 from the body portion 110 can be prevented. In addition, the connection body 131 may have a screw thread formed on an inner circumferential surface of the other end thereof to be screwed with a screw thread formed on an outer circumferential surface of the branch pipe 20 .

The sealing body 132 may be disposed between the inner bent portion of the second connection portion 130 and the outer bent portion of the body portion 110 . The sealing body 132 may block a gap between the second connection part 130 and one end of the body part 110 . Here, the sealing body 132 may be made of a water expansion resistant material that can expand when exposed to moisture. In general, the water expansion support material may be a material that gradually expands when contact with water using modified rubber as a main raw material. Therefore, when a gap occurs between the first connection part 120 and the body part 110 and fire prevention water leaks, the sealing body 132 expands and can seal the air gap and the leaking water path.

The connection rib 133 may be formed on an outer circumferential surface of the connection body 131 and may couple the connection body 131 to the operating unit 160 . In the following, a case in which the connecting rib 133 is provided singly will be described as an example. The connecting rib 133 may extend along the circumferential direction from the outer circumferential surface of the connecting body 131 . Here, the circumferential direction may be a circumferential direction of a circle having one direction as a central axis. The connecting rib 133 may extend along the outer circumferential surface of the connecting body 131 and have a certain curvature. The connection rib 133 may have a first groove 1 133a in which one side and the other side are recessed inward in one direction. A coupling protrusion 161a of the operating unit body 161 to be described later may be inserted into the first groove 1 133a and fitted into the first groove 1 133a. For example, the connecting rib 133 may have an 'H' shape in cross section. The connection rib 133 may be manufactured separately from the connection body 131 and coupled by welding or the like. The structure and shape of the connection rib 133 is not limited thereto and may vary.

The first gear tooth 134 may be connected to the operating unit 160 and installed on an outer circumferential surface of the connecting body 131 . The first gear teeth 134 may mesh with second gear teeth 162b to be described later. The first gear teeth 134 may extend along the outer circumferential surface of the connecting body 131 . The first gear teeth 134 may have a plurality of gear teeth protruding outward. For example, the first gear tooth 134 may include a rack gear having a predetermined curvature. However, the structure and shape of the first gear teeth 134 are not limited thereto and may vary.

Meanwhile, the rotation of the connection body 131 by the operation unit 160 will be described in more detail while describing the operation unit to be described later.

The collection part 140 is coupled to the body part 110, and at least a part is located at the lower part of the connection part where the second connection part 130 and the branch pipe 20 are connected (ie, the other end of the second connection part 130). It is disposed and its upper part is open, and may have a collection space 142a to collect fire-fighting water leaking from the connection part. The collection unit 140 may include a coupling bar 141 , a collection box 142 and a weight 143 .

The coupling bar 141 may be rotatably coupled to the body portion 110 . Meanwhile, the coupling bar 141 may be formed by being fixed to the body portion 110 . In the following, a case in which the coupling bar 141 is rotatably coupled to the body portion 110 will be described as an example. The coupling bar 141 extends along the radial direction of the body portion 110, and a through hole may be provided at an upper end thereof along one direction. The diameter of the aforementioned hole may be smaller than the outer diameter of the body portion 110 and longer than the outer diameter of the groove of the body portion 110 . Accordingly, the coupling bar 141 may be rotatably coupled to the groove of the body portion 110 through the hole.

The collection box 142 may extend along one direction from the coupling bar 141 and form a collection space 142a. The collection box 142 may be provided as a box with an open top. Meanwhile, the collection box 142 may cover a predetermined area along one direction from the lower side based on a connection portion where the second connection portion 130 and the branch pipe 20 are connected. Accordingly, fire prevention water leaking from the connection portion may fall downward and be collected in the collection space 142a of the collection box 142 .

In addition, the collection box 142 may be formed such that a lower surface of an inner circumferential surface forming the collection space 142a is inclined downward toward the center from one end and the other end thereof in one direction. That is, the collection box 142 may be formed in a shape in which its inner circumferential surface is linearly depressed from both ends toward the center. Accordingly, the fire-fighting water collected in the collection box 142 may be collected in the center thereof, and the detector 151 of the alarm unit 150 to be described later may more easily detect the fire-fighting water.

The weight 143 is installed at the lower part of the collection box 142, so that the collection box 142 can always be located at the bottom of the body 110 based on the vertical direction (ie, any one of the radial directions). , it is possible to apply a load to the collection box 142. Accordingly, even when the collection box 142 is rotatably coupled to the body 110 by the coupling bar 141, its position may always be disposed below the body 110 through the weight 143.

The alarm unit 150 is coupled to the collection unit 140 and is driven by firefighting water leaked from the connection portion to notify the outside whether firefighting water is leaked. The alarm unit 150 may include a sensor 151 , a determiner 152 , and an alarm unit 153 . In addition to this, the alarm unit 150 may further include a controller 154 capable of selectively driving an operation unit 160 to be described later.

The sensor 151 is installed in a relatively low-height center of the inner circumferential surface of the collection box 142 and can detect humidity according to the amount of moisture in the collection space 142a. Here, the detector 151 may be provided with any one of a capacitive humidity sensor, a resistive humidity sensor, and a thermal humidity sensor. A case in which the detector 151 according to an embodiment of the present invention is provided as an electrostatic humidity sensor that measures relative humidity by placing a thin metal oxide strip between two electrodes will be described as an example.

The determiner 152 is connected to the detector 151, and compares the measured value measured by the detector 151 with a preset set value, and when the measured value exceeds the set value, it can be determined that leakage has occurred in the connection portion. there is. The determiner 152 may set the first to third set values as the set values.

The alarm unit 153 is connected to the judging unit 152, and when the judging unit 152 determines that water leakage has occurred in the connection portion, it can notify by at least one of a visual method and an audible method. The alarm device 153 may include a first alarm member 153a and a second alarm member 153b and a control system module (not shown).

The first alarm member 153a includes a first light source 153aa emitting a frequency of 400 THz or more to less than 508 THz and a wavelength of 590 nm or more to less than 620 nm, and a frequency of 508 THz or more to less than 526 THz and a wavelength of 570 nm or more to less than 590 nm. It may include a second light source 153ab that emits, and a third light source 153ac that emits a frequency of 526 THz or more to less than 789 THz and a wavelength of 380 nm or more to less than 570 nm. Accordingly, the first light source 153aa may emit red light, the second light source 153ab may emit yellow light, and the third light source 153ac may emit blue light. Here, the first light source 153aa to the third light source 153ac may be individually and selectively driven by the control system module of the alarm unit 153 .

The second alarm member 153b includes a first sound source 153ba emitting a sound of 40 dB or more to less than 60 dB, a second sound source 153bb emitting a sound of 60 dB or more to less than 80 dB, and 80 dB or more to a third sound source 153bc emitting a sound of less than 100 dB. Here, the first sound source 153ba to the third sound source 153bc may be individually and selectively driven by the control system module of the alarm unit 153 .

That is, the control system module of the alarm device 153 drives the first light source 153aa and the first sound source 153ba when the determiner 152 determines that the measured value exceeds the first set value, thereby providing visual It can be notified in a method and audible way. In addition, the control system module of the alarm unit 153 stops driving the first light source 153aa and the first sound source 153ba when the determination unit 152 determines that the measured value exceeds the second set value, and , By driving the second light source 153ab and the second sound source 153bb, notification can be made in a visual method and an auditory method. In addition, the control system module of the alarm unit 153 stops driving the second light source 153ab and the second sound source 153bb when the determination unit 152 determines that the measured value exceeds the third set value, , By driving the third light source 153ac and the third sound source 153bc, notification can be made in a visual method and an auditory method. Accordingly, when water leakage occurs at the connection between the second connection part 130 and the branch pipe 20, when firefighting water is collected in the collection box 142, the detector 151 can detect firefighting water and detect the firefighting water leaking. Depending on the amount, a visual notification and an audible notification of different sizes may inform the user of the leakage of fireproof water.

The controller 154 is connected to the determiner 152, and when the determiner 152 determines that leakage has occurred in the connection portion, the second connection portion is driven by an operation motor 162a of the operation unit 160 to be described later. (130) can be rotated to advance its position in one direction. To this end, the controller 154 may be provided to exchange electromagnetic signals with the operating motor 162a.

Meanwhile, when the controller 154 rotates the second connector 130 to move forward along one direction, the rotation degree (ie, angle) of the second connector 130 may be adjusted. To this end, the controller 154 may include a plurality of confirmation sensors 154a and a control module (not shown).

A plurality of confirmation sensors (154a) is installed on the connection body 131, at least one of the plurality of measuring devices may be disposed to face the operating unit body (161). The plurality of confirmation sensors 154a may be laser sensors, and may measure a length in a circumferential direction from each position to the operating unit body 161 . Here, the length in the circumferential direction may include a curved length from the confirmation sensor 154a to the body of the actuator. In an embodiment of the present invention, a case in which two confirmation sensors 154a are provided will be described as an example. Each of the plurality of confirmation sensors 154a may sense a length in the circumferential direction from its own position to the actuator body 161 .

The control module may calculate the rotation angle of the connection body 131 by the operating unit body 161 to be described later through the measurement values measured by the plurality of confirmation sensors 154a. That is, the rotation angle of the connection body 131 may be calculated by converting the length in the circumferential direction measured by the plurality of confirmation sensors 154a into rotation angle. Accordingly, when the control module drives the actuator 162 (ie, the actuating motor 162a) of the operating unit 160, the gap between the connection body 131 and the branch pipe 20 disappears and no leakage occurs. , the second connector 130 may be rotated.

The operating unit 160 may rotate the connection body 131. The operating unit 160 may include an operating unit body 161 coupled to the connecting rib 133, an actuator 162 capable of transmitting a driving force to the operating unit body 161, and a support (not shown).

At least a part of the operating unit body 161 may come into contact with the outer circumferential surface of the connecting body 131 and may be movably coupled to the connecting rib 133 . To this end, the operating unit body 161 may be formed extending along the outer circumferential surface of the connecting body 131 while having a certain curvature. In addition, coupling protrusions 161a may be formed at upper and lower portions of the operating unit body 161 to protrude inwardly. As described above, the pair of coupling protrusions 161a may be inserted into the first grooves 1 133a of the connecting rib 133. That is, the operating unit body 161 extends in the circumferential direction, and a space may be provided therein in the same shape and size as the connection rib 133 . That is, the operating unit body 161 may have an 'H' shaped inner space extending in the circumferential direction therein. Accordingly, the connecting rib 133 is inserted into the operating unit body 161, and the coupling protrusion 161a and the first groove 1 (133a) are coupled to the operating unit body 161 and the connecting rib 133. You can stay connected.

In addition, the formed length of the operating unit body 161 may be longer than the formed length of the connecting rib 133. Therefore, when the connecting rib 133 is inserted into the inside of the operating unit body 161, there is a spare space inside the operating unit body 161 in which the connecting rib 133 can move by a predetermined length along the circumferential direction. can Accordingly, when the first gear tooth 134 moves in the circumferential direction through the second gear tooth 162b to be described later, the connecting rib 133 may also move within the operating unit body 161. Here, the structure and shape of the operating unit body 161 is not limited thereto and may vary.

The actuator 162 may be installed on the actuator body 161 and connected to the first gear tooth 134 . The actuator 162 may include a second gear tooth 162b connected to the operation motor 162a and the first gear tooth 134 .

The operation motor 162a serves to generate rotational driving force. For example, the operation motor 162a may be a motor and generate rotational force. The operating motor 162a may be installed on the side of the operating unit body 161 . Also, the operation motor 162a may include a shaft. The shaft is formed of a cylindrical rod and may connect the operation motor 162a and the second gear teeth 162b. However, the location where the operation motor 162a is installed and the method for generating the driving force are not limited thereto and may vary.

A shaft is inserted into the center of the second gear tooth 162b and may be engaged and connected to the first gear tooth 134 . To this end, the second gear teeth 162b may have a hollow cylindrical shape with gear teeth formed on an outer circumferential surface. For example, the second gear teeth 162b may be formed as pinion gears to engage with the first gear teeth 134 . The second gear teeth 162b may receive driving force from the operation motor 162a through the shaft, and may engage and rotate with the first gear teeth 134 through the driving force. Therefore, as described above, the first gear tooth 134 can be moved in the circumferential direction, and the connection body 131 fixedly coupled to the first gear tooth 134 through the movement of the first gear tooth 134 ) can be rotated.

The support may serve to support the operating unit body 161 . That is, the operating motor 162a operates to rotate the second gear tooth 162b, and the first gear tooth 134 meshing with the second gear tooth 162b along with the connecting body 131 along the circumferential direction. In rotation, since the support fixes and supports the actuator body 161, the actuator body 161 can rotate only the connection body 131 in a fixed state. To this end, the support is fixed at a position biased toward one end with respect to the center of the body portion 110, and may be coupled to the operating unit body 161 to support the operating unit body 161. In addition, the support may be provided by, for example, a manipulator and fixed to a wall of a workplace where the extension pipe 10 or the branch pipe 20 is located. However, the structure and shape of the support is not limited thereto and may be provided in any form for supporting the operating unit body 161 .

Meanwhile, the first connection unit 120 may have the same structure as the second connection unit 130 . In this case, the first connection unit 120 may have the same detailed configuration as the second connection unit 130 . In addition, the operation unit 160 may be provided in plurality so as to drive the first connection unit 120 in addition to the second connection unit 130 .

In this way, the fire piping connection device is firmly coupled to the new pipe and the branch pipe, and the new side pipe and the branch pipe can be kept firmly maintained without being separated from each other. Accordingly, the fire-fighting water may not leak out of the expansion pipe and the branch pipe. In addition, when a gap occurs with a branch pipe supplying fire-fighting water, leaking fire-fighting water may be collected and collected to detect leakage of fire-fighting water. Therefore, depending on whether there is water leakage, the gap between the branch pipe and the branch pipe may be blocked by rotating the second connection unit coupled to the branch pipe. In addition, the supply amount of fire-fighting water supplied from the branch pipe to the expansion pipe can be organically controlled. Accordingly, it is possible to selectively control the amount of sprayed fire extinguishing water.
