[0025] Please refer to Figures 1 to 4 , and now the tunnel fire recognition and monitoring device provided by the present invention will be described. The tunnel fire recognition and monitoring device includes an I-beam 10, two traveling members 20, a U-shaped frame 40, a plug-in member 50, and a monitoring member 60. The I-beam 10 is used to be connected to the inner top wall of the tunnel and extends along the trend of the tunnel; the two traveling members 20 are disposed on both sides of the web 12 of the I-beam 10 and are in rolling cooperation with the top wall of the lower flange 11 of the I-beam 10 along the trend of the I-beam 10. Horizontal plates 30 extending outward of the I-beam 10 are provided on both of the two traveling members 20. A plug block 31 is provided on the bottom wall of the horizontal plate 30, and a first insertion hole 32 is horizontally penetrated through the plug block 31; the U-shaped frame 40 straddles the bottom of the I-beam 10. The U-shaped frame 40 has two extension arms 41 extending upward and located on both sides of the I-beam 10 respectively. A slot 42 for accommodating the plug block 31 is provided at the upper end of the extension arm 41, and a second insertion hole 43 communicating with the slot 42 is horizontally penetrated through the extension arm 41; the plug-in member 50 is inserted into the first insertion hole 32 and the second insertion hole 43; the monitoring member 60 is disposed at the bottom of the U-shaped frame 40 and is used to recognize and monitor a fire.

[0026] In the actual use process of the tunnel fire recognition and monitoring device provided by the embodiment of the present application, when it is necessary to disassemble and repair the fire recognition and monitoring device, only by pulling the plug-in member 50 out of the first insertion hole 32 and the second insertion hole 43, the horizontal plate 30 and the U-shaped frame 40 can be separated, so that the fire recognition and monitoring device can be quickly disassembled from the I-beam 10, improving the disassembly efficiency.

[0027] During installation, simply align the insertion block 31 with the slot 42 and insert it, align the first jack 32 with the second jack 43, and insert the connector 50 into the first jack 32 and the second jack 43, thus completing the rapid installation of the fire recognition and monitoring device. Control the walking member 20 to walk along the direction of the I-beam 10, and the monitoring member 60 recognizes and monitors the fire.

[0028] Compared with the prior art, when the fire recognition and monitoring device needs to be disassembled and repaired, the tunnel fire recognition and monitoring device provided in this embodiment only needs to pull the connector 50 out of the first jack 32 and the second jack 43 to separate the cross plate 30 from the U-shaped frame 40, so as to quickly disassemble the fire recognition and monitoring device from the I-beam 10, improving the disassembly efficiency.

[0029] In a possible implementation manner, the above-mentioned connector 50 adopts the structure as shown in Figure 1 and Figure 3 See Figure 1 and Figure 3 , and a magnet 51 for adsorbing the extension arm 41 is connected to one end of the connector 50 and is located inside the extension arm 41.

[0030] Specifically, after the connector 50 is inserted into the first jack 32 and the second jack 43, the magnet 51 adsorbs on the extension arm 41, so that the connector 50 is stably inserted into the first jack 32 and the second jack 43, avoiding the connector 50 from coming out of the first jack 32 and the second jack 43 during walking, and improving the connection stability between the cross plate 30 and the U-shaped frame 40.

[0031] During disassembly, simply pull the connector 50 out of the first jack 32 and the second jack 43 to separate the cross plate 30 from the U-shaped frame 40, improving the disassembly convenience.

[0032] In some embodiments, see Figure 3 , two insertion blocks 31 are arranged at intervals along the direction of the I-beam 10 on each cross plate 30, two slots 42 are arranged on each extension arm 41, and the two slots 42 are arranged in one-to-one correspondence with the two insertion blocks 31.

[0033] Specifically, two second jacks 43 are arranged on each extension arm 41, the two second jacks 43 are respectively communicated with the two slots 42, and a connector 50 is inserted into each group of the first jack 32 and the second jack 43, further improving the connection stability between the cross plate 30 and the U-shaped frame 40.

[0034] In a possible implementation manner, the above-mentioned walking member 20 adopts the structure as shown in Figures 1 to 3 See Figures 1 to 3, the walking member 20 includes two driving wheels 21 spaced along the running direction of the I-beam 10. The driving wheels 21 are rotatably connected to the bottom of the cross plate 30 and are in rolling cooperation with the lower flange 11 along the running direction of the I-beam 10. One side of the driving wheel 21 is connected with a driving member 22 for driving the driving wheel 21.

[0035] Specifically, the driving member 22 is a 42 stepping motor. The driving member 22 is connected to the bottom of the cross plate 30. The driving member 22 has a driving end extending away from the web 12. The driving wheel 21 is connected to the driving end of the driving member 22 through a rotating shaft, and the driving member 22 drives the driving wheel 21 to rotate.

[0036] In some embodiments, referring to Figure 1 , the cross plate 30 is provided with an avoidance cavity 33 penetrating in the up-down direction for avoiding the driving wheel 21.

[0037] Specifically, the setting of the avoidance cavity 33 can provide sufficient space for the driving wheel 21 to avoid interference between the driving wheel 21 and the cross plate 30 during the rotation process.

[0038] In a possible implementation manner, the above-mentioned cross plate 30 adopts the structure as shown in Figures 1 to 3 , referring to Figures 1 to 3 , a guiding member 70 is provided on the top of the cross plate 30. One end of the guiding member 70 close to the web 12 is rotatably connected with a guide wheel 71 that abuts against and is in rolling cooperation with the web 12.

[0039] Specifically, under the action of the guide wheel 71 that abuts against and is in rolling cooperation with the web 12, the fire recognition and monitoring device walks stably along the running direction of the I-beam 10, avoiding rubbing between the cross plate 30 and the web 12. At the same time, the guide wheel 71 can also limit the upward jumping of the fire recognition and monitoring device, enabling the walking member 20 to stably roll cooperate with the lower flange 11, improving the walking stability.

[0040] In some embodiments, referring to Figures 1 to 4 , the guiding member 70 includes a guiding cylinder 72, an elastic member 73 and a pushing platform 74. The guiding cylinder 72 is connected to the top of the cross plate 30 and is arranged with an opening facing the web 12; the elastic member 73 is connected to the inner bottom wall of the guiding cylinder 72 and extends towards the web 12; the pushing platform 74 is connected to the extending end of the elastic member 73 and is slidably connected with the guiding cylinder 72, and the guide wheel 71 is rotatably connected to one end of the pushing platform 74 close to the web 12.

[0041] Specifically, by pushing the pushing platform 74 with the elastic member 73, the pushing platform 74 drives the guide wheels 71 to abut against the side wall of the web 12. The two guiding members 70 are symmetrically arranged on both sides of the web 12, and the two guide wheels 71 respectively abut against the side walls on both sides of the web 12, so as to realize the flexible clamping of the web 12 by the two guide wheels 71, which facilitates the rolling cooperation between the guide wheels 71 and the web 12. Thus, the guide wheels 71 can also adaptively clamp the webs 12 with different thicknesses, and prevent the fire recognition and monitoring device from horizontally moving along the length direction perpendicular to the I-beam 10, improving the practicability.

[0042] Further, a chute extending along the axial direction of the pushing platform 74 is provided on the inner side wall of the guiding cylinder 72, and a sliding block slidably matched with the chute is provided on the outer peripheral wall of the inner end of the pushing platform 74.

[0043] In some embodiments, referring to Figures 1 to 4 , a guiding column 75 extending away from the web 12 and penetrating through the bottom wall of the guiding cylinder 72 is connected to one end of the pushing platform 74 away from the web 12, and the elastic member 73 is sleeved on the outer periphery of the guiding column 75.

[0044] Specifically, the guiding column 75 guides the pushing platform 74, so that the pushing platform 74 stably slides in the guiding cylinder 72 along the horizontal direction, avoiding the situation that the pushing platform 74 is skewed during the telescopic process, and improving the stability.

[0045] In some embodiments, referring to Figures 1 to 3 , two guide wheels 71 are arranged at intervals in the vertical direction.

[0046] Specifically, two guide wheels 71 are correspondingly arranged on each guiding member 70 at intervals in the vertical direction, further improving the stability of the rolling cooperation between the guide wheels 71 and the web 12.

[0047] In a possible implementation manner, the above-mentioned monitoring member 60 adopts the structure as shown in Figures 1 to 3 , referring to Figures 1 to 3 , the monitoring member 60 includes a flame sensor 61, a smoke sensor 62, an industrial camera 63, a signal receiver 64 and an independent power supply 65. The flame sensor 61 is arranged at the bottom of the U-shaped frame 40 for detecting flames; the smoke sensor 62 is arranged at the bottom of the U-shaped frame 40 for detecting smoke; the industrial camera 63 is arranged at the bottom of the U-shaped frame 40 for taking pictures; the signal receiver 64 is arranged on the inner top wall of the U-shaped frame 40 and is electrically connected to the flame sensor 61, the smoke sensor 62 and the industrial camera 63 respectively. The signal receiver 64 can receive the signals emitted by the flame sensor 61 and / or the smoke sensor 62 and transmit a photographing signal to the industrial camera 63; the independent power supply 65 is arranged on the inner top wall of the U-shaped frame 40 and is electrically connected to the flame sensor 61, the smoke sensor 62, the signal receiver 64 and the industrial camera 63 respectively for power supply.

[0048] Specifically, the smoke sensor 62 is very sensitive to smoke and detects harmful gases such as combustible gases and smoke, so as to cooperate with the flame sensor 61 to detect the fire flame. When the smoke sensor 62 detects smoke, it can transmit a signal to the signal receiver 64. When the flame sensor 61 detects a flame, it can transmit a signal to the signal receiver 64. The signal receiver 64 receives the signals from the smoke sensor 62 and / or the flame sensor 61, and can transmit the signals to the industrial camera 63, enabling the industrial camera 63 to take on-site photos and providing image information of the fire phenomenon on the staff's computer, thus improving the convenience.

[0049] The independent power supply 65 supplies power to the flame sensor 61, the smoke sensor 62, the signal receiver 64 and the industrial camera 63, facilitating the normal use of the electronic devices.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
