[0020] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0021] Hereinafter, a road tunnel fire detection system according to the present invention will be described with reference to the attached drawings.

[0022] FIG. 1 is a drawing showing a road tunnel fire detection system (1) according to the present invention installed inside an actual tunnel.

[0023] FIGS. 2 and 3 show that a road tunnel fire detection system according to the present invention includes a detection member (100), a driving member (200), a fire extinguishing member (300), and a control member (400).

[0024] The above-mentioned sensing member (100) is formed as an arch structure corresponding to the interior of the tunnel and moves inside the tunnel according to the driving of the driving member (200) formed at both ends, and detects parameters related to fire occurrence in the direction of the road.

[0025] More specifically, the sensing member (100) includes an arch frame (110), a straight frame (120), and a sensing module (130).

[0026] The above arch frame (110) is structured to correspond to the interior of an arch-shaped tunnel so that the fire extinguishing member (300) or detection module (130) can be installed and supported.

[0027] The above arch frame (110) may be a plate-shaped structure with a hollow interior, unlike the straight frame (120) which is cylindrical, and is not limited thereto, may be a cylindrical shape with a different diameter, similar to the straight frame (120).

[0028] The straight frame (120) is extended at both ends of the arch frame (110) and combined with the driving member (200).

[0029] The above straight frame (120) is cylindrical, hollow inside, and has screw threads formed on its inner surface to be coupled with the driving member (200).

[0030] As shown in FIG. 3, the above detection module (130) is formed in a plurality at predetermined intervals on the arch frame (110) and includes a temperature sensor (131), a humidity sensor (132), a gas sensor (133), and an image sensor (134) to detect parameters capable of determining whether there is a fire.

[0031] The temperature sensor (131) measures the temperature inside the tunnel and transmits it to the control member (400) so that the control member (400) can determine whether a fire has occurred.

[0032] In addition, the humidity sensor (132) measures the humidity inside the tunnel and transmits it to the control member (400) so that the control member (400) can determine whether a fire has occurred.

[0033] In addition, the gas sensor (133) measures the gas inside the tunnel and transmits it to the control member (400) so that the control member (400) can determine whether a fire has occurred.

[0034] In addition, the image sensor (134) photographs the inside of the tunnel so that the control member (400) can determine whether a fire has occurred through image processing.

[0035] In particular, the image sensor (134) captures flames, fire, etc. when a fire occurs inside the tunnel.

[0036] The control member (400) receives the temperature, humidity, and gas values ​​measured by the temperature sensor (131), humidity sensor (132), and gas sensor (133), and determines that a fire has occurred when a temperature significantly higher than usual, a different humidity, or toxic gas is detected, taking into account the time, season, weather, etc.

[0037] In addition, the control member (400) can determine that a fire has occurred if a flame or fire is detected in the image through image processing using the image captured by the image sensor (134).

[0038] The detection module (130) is not limited to a temperature sensor (131), a humidity sensor (132), and a gas sensor (133), and may include other sensors capable of detecting parameters capable of determining the occurrence of a fire.

[0039] The driving member (200) is formed at both ends of the sensing member (100) to generate driving force, thereby enabling the sensing member (100) to move back and forth inside the tunnel.

[0040] More specifically, the driving member (200) includes a support frame (210), a driving motor (220), a chain gear (230), a chain (240), and a driving wheel (250).

[0041] The support frame (210) has a trapezoidal structure with a predetermined thickness so that the wheel (250) can be partially accommodated and rotated, and has a hollow interior and an open bottom.

[0042] The above support frame (210) is a trapezoidal structure with a certain thickness and a hollow interior, with all sides closed and only the bottom open.

[0043] The driving motor (220) is formed on the support frame (230) and generates rotational force, which is then transmitted to the driving wheel (250).

[0044] The above driving wheels (250) are formed on both sides of the driving motor (220) and rotate by receiving rotational force from the driving motor (220), thereby enabling the road tunnel fire detection system according to the present invention to travel back and forth inside the tunnel.

[0045] Additionally, the driving wheel (250) is formed to be rotatable by receiving support from a rotation axis formed on both sides of the hollow interior of the support frame (230).

[0046] The above chain gear (230) is formed on the rotation axis of the above driving motor (220).

[0047] Additionally, the chain gear (230) is formed so that a rotating shaft passing through the driving wheel (250) passes through it and is fixed to the driving wheel (250).

[0048] The above chain (240) is connected to the chain gear (230) of the driving motor (220) and the chain gear (230) of the driving wheel (250), so that the rotational force of the driving motor (220) can be simultaneously transmitted to the driving wheels (250) formed on both sides of the driving motor (220).

[0049] Although the driving wheels (250) of the road tunnel fire detection system according to the present invention are shown as being formed in two numbers in FIG. 4, they are not limited thereto. In order to prevent the road tunnel fire detection system from tipping over, three or more multiple wheels may be formed in series (in a row), and a chain gear (230) formed on each driving wheel (250) may be connected by a chain (240) to simultaneously receive rotational force from a driving motor (220).

[0050] Meanwhile, the driving member (200) of the road tunnel fire detection system according to the present invention further includes a driving assistance module (260) formed outside the support frame (210) as shown in FIG. 4a and FIG. 4c.

[0051] The above driving assistance module (260) is configured to prevent the driving force from decreasing as it comes into contact with the inner wall when the road tunnel fire detection system according to the present invention travels inside the tunnel.

[0052] More specifically, the driving assistance module (260) includes an auxiliary wheel (261), an auxiliary wheel frame (262), and an auxiliary motor (263).

[0053] The above auxiliary wheel (261) is formed to be rotatable in the horizontal direction and is configured to rotate when in contact with the inner wall of the tunnel.

[0054] As shown in FIG. 4a, the auxiliary wheel frame (262) is formed outside the support frame (210) so that the auxiliary wheel (261) can rotate in the horizontal direction.

[0055] The above auxiliary motor (263) has a rotating shaft that is directly connected to the auxiliary wheel (261) or is indirectly connected to the auxiliary wheel (261) by a gear (bevel gear, pinion-ground gear, etc.) to assist in driving the road tunnel fire detection system according to the present invention.

[0056] For example, the above auxiliary motor (263) applies driving force in the forward direction during the uphill section inside the tunnel and reduces driving force in the reverse direction during the downhill section of the road tunnel fire detection system according to the present invention.

[0057] In addition, the driving member (200) of the road tunnel fire detection system according to the present invention further includes a height adjustment module (270) as shown in FIG. 4.

[0058] The height adjustment module (270) includes a height adjustment motor (271) and a height adjustment shaft (272) to adjust the height of the sensing member (100).

[0059] The height adjustment module (270) can adjust the height to adjust the detection sensitivity of the detection member (100) and can also adjust the height to prevent the arch-shaped detection member (100) from colliding with facilities such as a ventilation fan installed on the ceiling of a tunnel.

[0060] More specifically, the height adjustment motor (271) is formed inside the support frame (210) and is formed so that rotational force can be generated in an upward direction, with the rotation axis exposed to the outside of the support frame (210).

[0061] The height adjustment shaft (272) is fixedly coupled to the rotation shaft of the height adjustment motor (271), and has a screw thread formed on its outer surface so that it is inserted into the straight frame (120) of the sensing member (100) and engages with the screw thread on its inner surface.

[0062] The above-mentioned fire extinguishing member (300) is formed to be movable along the arch frame (110) of the above-mentioned detection member (100) so as to drop a drop-type fire extinguishing liquid to suppress the fire in its early stages.

[0063] More specifically, as illustrated in FIG. 5, the fire extinguishing member (300) includes a bidirectional motor (310), a pinion gear (320), a crown gear (330), a case (340), a wheel shaft (350), a wheel (360), a fire extinguishing liquid bottle (370), and a fire extinguishing liquid dispensing part (380).

[0064] The above bidirectional motor (310) has a rotating shaft formed in both directions and generates rotational force in both directions.

[0065] The pinion gear (first gear: 320) transmits rotational force to the crown gear (330) which is formed on the bidirectional rotation axis of the bidirectional motor (310) and meshes with it.

[0066] The crown gear (second gear: 330) meshes with the pinion gear (320) to convert rotational force at a right angle and transmit it to the wheel (350).

[0067] At this time, the bidirectional motor (310) and the wheel (360) may be connected gearwise by a different gear, such as a bevel gear, rather than the pinion gear (320) and the crown gear (330), to receive power.

[0068] At this time, the upper and lower pinion gears (320) and crown gears (330) are formed with different gear ratios so that the upper and lower wheels (360) can easily move the arch-shaped arch frame (110), thereby allowing the rotation of the upper and lower wheels (360) to be controlled differently.

[0069] In addition, the bidirectional motors (310) may be formed as independent motors so that the upper and lower wheels (360) can easily move the arch-shaped arch frame (110).

[0070] The above case (340) casing the bidirectional motor (310), pinion gear (320), and crown gear (330) is contained inside.

[0071] One end of the wheel shaft (350) is coupled to the pinion gear (320), and the other end is coupled to the wheel (360) so that the rotational force generated by the bidirectional motor (310) can finally be transmitted to the wheel (360).

[0072] A pair of wheels (360) that receive rotational force from the bidirectional motor (310) move along a moving rod (111) formed on the arch frame (110).

[0073] The above-mentioned fire extinguishing liquid bottle (370) has a structure in which a metal upper lid is combined with a glass lower bottle and contains fire extinguishing liquid inside.

[0074] The above fire extinguishing liquid bottle (370) breaks as it falls from a predetermined height, allowing the internal fire extinguishing liquid to spread and enable initial fire suppression.

[0075] The above-mentioned digestive liquid dispensing part (380) is formed by being coupled to the above-mentioned case (340) and an electromagnet (381) is formed, and a battery (382) is built inside, and under the control of the above-mentioned control member (400), the power of the battery (382) is supplied to or cut off from the electromagnet (381), thereby generating and extinguishing the magnetic force of the corresponding electromagnet (381).

[0076] In particular, the electromagnet is attached to the top lid of the fire extinguishing liquid bottle (370) so that when the power is cut off, the magnetic force is extinguished, allowing the fire extinguishing liquid bottle (370) to fall from the location where the fire occurred, as shown in FIG. 6.

[0077] As mentioned above, the control member (400) controls the driving member (200), controls the extinguishing member (300), and controls the detection member (100) so that the road tunnel fire detection system can move.

[0078] In particular, the above control member (400) includes a communication module (410) composed of a short-range communication unit (411) and a long-range communication unit (412), making it possible to notify a fire department of the occurrence of a fire through communication when a fire occurs.

[0079] Although the technical concept of the present invention has been described above together with the accompanying drawings, this is merely an illustrative explanation of preferred embodiments of the present invention and is not intended to limit the invention. Furthermore, it is evident that anyone with ordinary knowledge in the technical field to which the present invention pertains can make various modifications and imitations within the scope of the technical concept of the present invention without departing from its scope.
