When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0031] Please refer to the attached Figure 1-3 In one embodiment of the utility model, a highway tunnel jet fire extinguishing device is provided, which includes a fixing plate 10, a horizontal adjustment mechanism 20, an installation box 30 and a jet mechanism 40. First of all, it should be noted that the fire extinguishing method in the prior art has higher requirements on the professional quality of fire extinguishing personnel. It often happens that trapped people in the tunnel cannot effectively use the fire extinguishing system, causing the fire to spread and causing accidents. This application solves the above-mentioned defects in the prior art by setting up a highway tunnel jet fire extinguishing device. The details are as follows:

[0032] The fixed plate 10 includes a fixed end (not shown in the figure) and a free end (not shown in the figure) that are relatively arranged, the fixed end is embedded in the inner wall of the tunnel, and the free end extends outward from the fixed end to the inner wall of the tunnel and is cantilevered, the horizontal adjustment mechanism 20 is connected to the bottom of the free end and can rotate in a horizontal plane, and the bottom end of the horizontal adjustment mechanism 20 is fixedly connected to the installation box 30.

[0033] Specifically, the highway tunnel jet fire extinguishing device in the present application includes a fixing plate 10, a horizontal adjustment mechanism 20, an installation box 30 and a jet mechanism 40. The fixing plate 10 is used for the installation of the horizontal adjustment mechanism 20 and the like; the horizontal adjustment mechanism 20 is used for the installation box 30 to be installed, and at the same time, the jet fire extinguishing angle can be changed by adjusting itself in the horizontal direction to enhance the targeted fire extinguishing; the installation box 30 is used for the connection of the jet mechanism 40.

[0034] Among them, the fixed plate 10 includes a fixed end and a free end that are relatively arranged. The fixed end is used to be embedded in the inner wall of the tunnel, so that the installation position is set at a higher position of the inner wall of the tunnel, so that the free end can be hoisted at a high place when the horizontal adjustment mechanism 20 is installed. When a fire occurs, the fire extinguishing coverage at a high place is wider and the fire extinguishing effect is better; because when a fire occurs, the fire location is not necessarily directly below the jet mechanism 40, the horizontal adjustment mechanism 20 can be used to adjust it at this time. The horizontal adjustment mechanism 20 can rotate in a horizontal plane. When it rotates, it drives the installation box 30 fixed at its bottom end to rotate together, and the jet mechanism 40 built into the installation box 30 rotates together, thereby realizing the switching of the fire extinguishing angle in the horizontal plane.

[0035] The installation box 30 has an installation chamber 310 therein, and the jet mechanism 40 includes a jet gun 410 and a water supply pipe 420, wherein the water outlet end of the jet gun 410 is arranged outside the installation box 30, and the water inlet end of the jet gun 410 is built into the installation chamber 310, and the water inlet end of the jet gun 410 is connected to the tunnel fire hydrant 60 through the water supply pipe 420, and the fixing plate 10, the horizontal adjustment mechanism 20 and the installation box 30 are sequentially provided with through holes from top to bottom for the water supply pipe 420 to pass through.

[0036] In detail, the installation chamber 310 is used for installing the jet mechanism 40, and the jet mechanism 40 includes a jet gun 410 and a water supply pipe 420. The jet gun 410 is a fire extinguishing jet device. The jet gun 410 is a relatively mature jet device, so it is not described in detail here. The water supply pipe 420 is used to communicate with the tunnel fire hydrant 60 that has been installed in the tunnel to obtain a water source for fire extinguishing; wherein the water inlet end of the jet gun 410 is built into the installation chamber 310, and at the same time, it is convenient for the installation box 30 to protect the jet gun 410 and the water supply pipe 4 20 to prevent the connection from being damaged by accidental external force and causing water leakage, so that the water outlet end of the jet gun 410 is suspended outside the installation box 30 to facilitate jet fire extinguishing; it is worth mentioning that since the installation box 30 is also sequentially arranged with the horizontal adjustment mechanism 20 and the fixed plate 10, and the water supply pipe 420 is usually buried in the side wall of the tunnel, in order to facilitate the pipeline arrangement of the water supply pipe 420, through holes are opened in the fixed plate 10, the horizontal adjustment mechanism 20 and the installation box 30 from top to bottom for the water supply pipe 420 to pass through.

[0037] As a preferred embodiment of the utility model, the bottom plate of the fixed plate 10 is provided with an annular groove 110, and the horizontal adjustment mechanism 20 includes a driving mechanism and a plurality of connecting rods 210 arranged at circumferential intervals along the annular groove 110, wherein the top end of the connecting rod 210 is slidably connected to the annular groove 110, the bottom end of the connecting rod 210 is fixedly connected to the installation box 30, the driving mechanism is fixed to the top of the installation box 30, and the driving end of the driving mechanism is fixedly connected to the connecting rod 210.

[0038] It should be noted that the horizontal adjustment mechanism 20 includes a driving mechanism and a plurality of connecting rods 210, and the driving mechanism is used for rotating the plurality of connecting rods 210, thereby driving the installation box 30 fixed to the bottom to rotate. Therefore, the annular groove 110 provided on the bottom plate of the fixing plate 10 is used to provide a rotation space for the connecting rod 210 when rotating, so that the top end of the connecting rod 210 can be slidably connected to the annular groove 110, that is, the annular groove 110 serves as a sliding track for the connecting rod 210; wherein, the driving mechanism can be in the form of providing a horizontal rotation driving force for the connecting rod 210 through a rotating motor, or in the form of driving the connecting rod 210 to rotate through a driving motor combined with a gear transmission, etc., and those skilled in the art can make a selection according to specific needs.

[0039] As a preferred embodiment of the utility model, it also includes a vertical telescopic rod 320 built into the installation chamber 310, the top end of the vertical telescopic rod 320 is fixedly connected to the installation box 30, and the bottom end of the vertical telescopic rod 320 is arranged near the water inlet end of the jet gun 410 and fixedly connected to the jet gun 410.

[0040] It should be noted that the vertical telescopic rod 320 is used to adjust the vertical height of the jet gun 410. When the fire at a distance from the jet gun 410 cannot be extinguished, the vertical telescopic rod 320 can be retracted to drive the jet gun 410 to move upward, thereby raising the position of the jet gun 410 and improving the jet fire extinguishing coverage.

[0041] As a preferred embodiment of the present invention, the number of the connecting rods 210 is two, and the two connecting rods 210 are arranged opposite to each other along the radial direction of the annular groove 110 .

[0042] It is worth noting that, since the installation box 30 is in the shape of a cubic box, taking into account the connection balance, the number of connecting rods 210 is two, so that the two connecting rods 210 are arranged radially opposite to each other along the annular groove 110. Although the more the number, the more stable the connection, too many numbers will affect the horizontal rotation. Therefore, preferably, two connecting rods 210 are set.

[0043] As a preferred embodiment of the utility model, it also includes a monitoring mechanism 50, which includes a camera 510 and a slide rail 520. The slide rail 520 is arranged close to the installation box 30 and fixedly connected to the side wall of the tunnel. The camera 510 is movably arranged on the slide rail 520 along the extension direction of the slide rail 520.

[0044] It is worth noting that the monitoring mechanism 50 can be used to monitor the fire situation, and can also be connected to the control system. When the monitoring mechanism 50 detects the occurrence of a fire, it can transmit information in real time through the control system and open the entire fire extinguishing device to extinguish the fire. It includes a camera 510 and a slide rail 520. The camera 510 is used to obtain real-time information, and the slide rail 520 is used for the movement of the camera 510. When the flame position cannot be identified or the fire source is blocked by thick smoke, the position of the camera 510 can be adjusted through the slide rail 520 to facilitate image acquisition; it is worth mentioning that a solenoid valve can be set at the tunnel fire hydrant 60, and both are electrically connected to the control system. When a fire occurs, the solenoid valve and the jet gun 410 are automatically triggered and opened by the control system to perform jet fire extinguishing. This control system is a relatively mature technology, so it will not be described in detail here.

[0045] Furthermore, the water outlet end of the jet gun 410 is tilted downward from the water inlet end.

[0046] It should be noted that since the jet gun 410 of the present application is arranged at a position close to the top, tilting the jet gun 410 downward can facilitate extinguishing the flame close to one end of the jet gun 410, and then adjusting the height through the vertical telescopic rod 320 to extinguish the flame farther away.

[0047] Furthermore, the jet mechanism 40 also includes a flexible pipe 430, which is arranged between the jet gun 410 and the water supply pipe 420, one end of the flexible pipe 430 is connected to the water inlet end of the jet gun 410, and the other end of the flexible pipe 430 is connected to the water supply pipe 420.

[0048] It should be understood that since the vertical telescopic rod 320 may need to be adjusted in height during jet fire extinguishing, in order not to affect the adjustment, a flexible pipe 430 is added between the jet gun 410 and the water supply pipe 420 to facilitate slight movement of the connection and avoid problems such as rupture and deformation of the connection.

[0049] Furthermore, the diameter of the water supply pipe 420 is 60 mm to 70 mm.

[0050] It should be noted that the larger the pipe diameter, the greater the water flow rate, but too large a diameter may lead to problems such as high cost. Therefore, preferably, the diameter of the water supply pipe 420 is 60mm to 70mm, and technical personnel in this field can set it according to actual conditions.

[0051] The present application also provides a highway tunnel jet fire extinguishing system, which also includes a plurality of highway tunnel jet fire extinguishing devices as described above, and the plurality of highway tunnel jet fire extinguishing devices are arranged at intervals along the longitudinal direction of the tunnel.

[0052] It should be noted that due to the long extension length of the tunnel, in order to ensure that the jet fire extinguishing coverage at various locations in the tunnel can be basically guaranteed, multiple jet fire extinguishing devices of the present application need to be installed, so that multiple of the highway tunnel jet fire extinguishing devices are arranged at intervals along the longitudinal direction of the tunnel.

[0053] Furthermore, the spacing distance between each two adjacent highway tunnel jet fire extinguishing devices is 40m to 60m.

[0054] It can be understood that, considering the coverage range, installation cost, etc. of jet fire extinguishing, the spacing distance between each two adjacent highway tunnel jet fire extinguishing devices can be set to 40m to 60m, and in a preferred embodiment, can be set to 50m.

[0055] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
