Description

Technical Field

[0001] This invention belongs to the field of tunnel fire protection and relates to a mobile, all-around automatic fire extinguishing device for highway tunnels. Background Technology

[0002] In the event of a fire in a tunnel, immediately call the fire department and use fire extinguishers and fire hydrants for initial firefighting. Pay attention to personal protection, teamwork, and escape and evacuation procedures. During firefighting, remain calm and operate in an orderly manner to minimize casualties and property damage. If the fire is in its early stages and small, try using the fire extinguishers provided in the tunnel or those carried in the vehicle. When using a fire extinguisher, stand upwind of the fire source and operate according to the steps of "lift, pull, aim, and press". If there are fire hydrants in the tunnel, quickly go to the fire hydrant and use it to extinguish the fire. To use a fire hydrant, press the fire hydrant box button to open the box door, take out the hose and nozzle, connect the hose and valve, open the valve counterclockwise, and spray water onto the fire source until the fire is extinguished. The operation is relatively complex.

[0003] Currently, some tunnels have adopted fire-fighting robots, but they still have the following drawbacks during use: they carry a variety of fire extinguishers, which affects their movement speed, and it is not easy to control the direction of the nozzles, making it impossible to accurately spray the fire source, thus reducing the fire extinguishing speed. Summary of the Invention

[0004] In view of this, in order to solve the problems of existing tunnel fire extinguishing devices that require carrying a variety of fire extinguishers, which affects the speed of movement, and that make it difficult to control the direction of the nozzles and accurately spray onto the fire source, thus reducing the fire extinguishing speed, the present invention provides a mobile all-around automatic fire extinguishing device for highway tunnels.

The bottom of the multiple second pins is fixedly connected to the lifting plate, and one of the second pins is used in conjunction with the insertion block.

[0011] Furthermore, a strip is fixedly provided on one side of the box body, and a slot for inserting the strip is provided on one side of the plug block, which is used to drive the second pin to disengage from the box body and for the plug block to insert into the box body.

[0012] Furthermore, two sliding pillars are slidably provided on the top of the insert block, and a tension spring is provided inside the insert block. The two ends of the tension spring are respectively fixedly connected to the bottom wall of the insert block at the bottom of the sliding pillar. The same pressure plate is fixedly provided on the top of the two sliding pillars, and two sets of first pins are fixedly provided on the bottom of the pressure plate.

[0022] 4. The mobile all-around automatic fire extinguishing device for highway tunnels disclosed in this invention, by setting at least three sets of boxes in the tunnel, can be used as close as possible to the fire source, which can reduce the movement of the inserts and further improve the fire extinguishing efficiency and make it more convenient to use.

[0023] 5. The mobile all-around automatic fire extinguishing device for highway tunnels disclosed in this invention can accurately move the fire extinguishing box above the fire source through the first motor, the second motor and the third motor, and adjust the spray position to cover the fire source, ensuring stability and accuracy in the fire extinguishing process. At the same time, it can selectively carry the corresponding box to move for different types of fires, effectively improving the emergency response capability and fire extinguishing efficiency of tunnel fires.

[0036] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0037] like Figures 1-2 The mobile automatic fire extinguishing device for highway tunnels shown includes three sets of fire extinguishing units installed along the length of the tunnel. These three sets of fire extinguishing units are securely installed inside the tunnel 1. Each set of fire extinguishing units includes two guide rails 2. A first slider 3 is slidably fitted onto the outer wall of one end of each guide rail 2. A second slider 4 is also slidably fitted onto the outer wall of the guide rail 2. A gripping mechanism is designed between the two first sliders 3 and the second slider 4 to enable the gripping and movement of the fire extinguishing agent container 9.

[0038] like Figure 4As shown, the specific structure of the gripping mechanism is as follows: A first mounting bracket 10 is fixedly installed on one side of one of the first sliders 3, and the first mounting bracket 10 is connected to the other first slider 3 through a first guide rod 13. Simultaneously, a second mounting bracket 24 is fixedly installed on one side of one of the second sliders 4, and a second screw 23 is rotatably connected between the second mounting bracket 24 and the other second slider 4. A first sliding ring 17 is sleeved on the outer wall of the first guide rod 13, and a support bracket 18 is fixedly installed on the outer wall of the first sliding ring 17. The other end of the support bracket 18 is connected to the second screw 23. An insert block 27 that inserts into the housing 9 is fixedly installed at one end of the support bracket 18. To drive the rotation of the second screw 23, a third motor 25 is fixedly installed on the inner wall of one side of the second mounting bracket 24, and the output end of the third motor 25 is fixedly connected to the second screw 23. When the third motor 25 is started, it drives the second screw 23 to rotate, thereby driving the support bracket 18 to move left and right through threaded transmission.

[0039] In addition, a fixing mechanism is provided on the support base 39 for fixing and releasing the box 9. For example... Figure 8 As shown, the fixing mechanism includes two guide grooves 45 formed on the top of the support base 39, with guide bars 44 slidably disposed within the guide grooves 45. Both guide bars 44 are fixedly disposed on the bottom of the box body 9. Multiple fixing posts 41 are fixedly disposed within the support base 39, and the same lifting plate 42 is slidably fitted onto the outer wall of the multiple fixing posts 41. Springs 43 are also fitted onto the outer wall of the fixing posts 41, with both ends of the springs 43 fixedly connected to the bottom of the lifting plate 42 and the bottom wall of the support base 39, respectively. Multiple insertion holes 40 are formed on the top of the support base 39, with multiple second pins 37 slidably disposed within the insertion holes 40 and inserted into the bottom of the box body 9. The bottoms of the multiple second pins 37 are all fixedly connected to the lifting plate 42. When the lifting plate 42 moves up and down, it will drive the second pin 37 to move synchronously, thereby fixing and releasing the box 9. At the same time, one of the second pins 37 can be used in conjunction with the insert block 27. During the movement of the insert block 27, the second pin 37 can be driven to move downward through the inclined surface at its bottom, thereby driving the other second pins 37 to move downward through the lifting plate 42, so that they are separated from the box 9.

[0040] like Figure 9 As shown, the interior of the housing 9 is divided into a first receiving chamber 46 and a second receiving chamber 47 for storing different types of fire extinguishing agents. Connecting pipes 48 are installed in both the first receiving chamber 46 and the second receiving chamber 47. Sprinklers 35 are fixedly installed on both outer walls of the housing 9, and both connecting pipes 48 are connected to the sprinkler heads 35. Thus, when the fire extinguishing agent is delivered to the connecting pipes 48, it can be sprayed through the sprinkler heads 35. An air pump is installed inside the housing 9, which pressurizes the fire extinguishing agent to propel it out through the connecting pipes 48 and the sprinkler heads 35.

[0041] To drive the gripping mechanism to move forward, backward, left, right, and tilt, such as Figure 5 As shown, driving assemblies are also provided on the two first sliders 3 and the second slider 4. The driving assembly includes a nut ring 21 threaded onto the outer wall of the second screw 23, a sliding block 22 fixedly mounted on the outer wall of the nut ring 21, and a groove 26 formed on the top of the support frame 18, in which the sliding block 22 is embedded. When the third motor 25 drives the second screw 23 to rotate, it drives the nut ring 21 to move left and right via threaded transmission, thereby causing the support frame 18 and the insert block 27 to move left and right. Simultaneously, to limit the movement of the nut ring 21, a third guide rod 19 is fixedly mounted between the second mounting frame 24 and the other second slider 4. A second sliding ring 20 is slidably mounted on the outer wall of the third guide rod 19, and the second sliding ring 20 is fixedly mounted on the nut ring 21.

[0042] To adjust the distance between the first slider 3 and the second slider 4, a second guide rod 14 is provided on one side of one of the first sliders 3, and one of the second sliders 4 is slidably sleeved on the second guide rod 14. A first screw 15 is rotatably mounted through one side of the other first slider 3, and the other second slider 4 is threaded onto the first screw 15. A second motor 16 is fixedly mounted on one side of the first slider 3, and the output end of the second motor 16 is fixedly connected to the first screw 15. When the second motor 16 is started, it drives the first screw 15 to rotate, thereby adjusting the distance between the first slider 3 and the second slider 4 through threaded transmission. During the distance adjustment process, the sliding block 22 and the groove 26 can be used to tilt the support frame 18 up and down.

[0043] To drive the first slider 3 to move back and forth on the guide rail 2, a first motor 11 is fixedly mounted on one side of the first mounting bracket 10. The output end of the first motor 11 extends into the first mounting bracket 10 and is fitted with a gear 12. On one side of one of the guide rails 2, a rack 7 that meshes with the gear 12 is fixedly mounted. When the first motor 11 is started, it drives the gear 12 to rotate, thereby driving the first slider 3 to move back and forth on the guide rail 2 through the meshing transmission of the gear and rack.

[0044] To enable the connection between the housing 9 and the insertion block 27, such as Figure 6As shown, an insert strip 38 is fixedly installed on one side of the box body 9, and a slot 31 for inserting the insert strip 38 is opened on one side of the insert block 27. When the insert block 27 is inserted into the box body 9, the insert strip 38 will be inserted into the slot 31, thereby achieving a stable grip on the box body 9. At the same time, it drives the second pin 37 to disengage from the box body 9 and the insert block 27 to be inserted into the box body 9. To further fix the box body 9 on the insert block 27, two sliding posts 29 are slidably installed on the top of the insert block 27, and a tension spring 30 is installed inside the insert block 27. The two ends of the tension spring 30 are fixedly connected to the bottom of the sliding post 29 and the bottom wall of the insert block 27, respectively. The top of the two sliding posts 29 is fixedly installed with the same pressure plate 28, and the bottom of the pressure plate 28 is fixedly installed with two sets of first pins 32. A positioning hole 36 for inserting the first pin 32 is opened on the top of the box body 9. When the pressure plate 28 is pressed down by the tension spring 30, the first pin 32 is inserted into the positioning hole 36. At this time, the box body 9 can be fixed to the insert block 27.

[0045] To facilitate the pressing of the pressure plate 28 by the tension spring 30, such as Figure 7 As shown, a rectangular opening 33 corresponding to the box body 9 is provided on one side of the connecting plate 8, and a bevel 34 for use with the pressure plate 28 is provided on one side of the connecting plate 8. When the pressure plate 28 is moved to one side of the connecting plate 8, the pressure plate 28 will contact the bevel 34 and be lifted. At the same time, a rectangular opening 33 corresponding to the box body 9 is also provided on one side of the connecting plate 8. When the pressure plate 28 moves into the rectangular opening 33, the tension spring 30 can drive the pressure plate 28 to move downward, thereby fixing the insert 27 to the box body 9.

[0046] When a fire occurs in a vehicle inside tunnel 1, cameras, temperature sensors, and smoke sensors inside tunnel 1 acquire fire data and control the corresponding first motor 11, second motor 16, and third motor 25 to operate. Simultaneously... Figure 3 The top of the first sliding block 3 shown is also fixedly provided with a connecting frame 5, and a storage battery 6 is provided on the connecting frame 5, which can provide power to the first motor 11, the second motor 16 and the third motor 25.

[0047] When this mobile highway tunnel all-around automatic fire extinguishing device is used, the device is installed inside tunnel 1. When a fire occurs in a vehicle inside tunnel 1, the camera, temperature sensor, and smoke sensor inside tunnel 1 acquire fire data and activate the corresponding third motor 25. The third motor 25 drives the second screw 23 to rotate. The rotation of the second screw 23 drives the nut ring 21 to move. During the movement of the nut ring 21, it drives the second sliding ring 20 to move on the third guide rod 19 to prevent the nut ring 21 from rotating. The movement of the nut ring 21 drives the sliding block 22 to move. The movement of the sliding block 22 drives the support frame 18 to move. The movement of the support frame 18 drives the first sliding ring 17 to move on the first guide rod 13. At the same time, it also drives the insertion block 27 to move until the insertion block 27 moves to one side of the corresponding box 9. Then start the first motor 11. The first motor 11 can drive the gear 12 to rotate. Since the rack 7 does not move when the gear 12 rotates, the gear 12 can drive the first slider 3 to move and drive the other first slider 3 to move through the first guide rod 13. At the same time, the first slider 3 can push the second slider 4 to move through the first screw 15. The movement of the second slider 4 can drive the second slider 4 on the other side to move through the second screw 23, thereby driving the insert block 27 to move along the length of the tunnel 1. When the pressure plate 28 contacts the connecting plate 8, it can drive the pressure plate 28 to move upward through the inclined edge 34 on one side of the connecting plate 8. The upward movement of the pressure plate 28 can drive the sliding column 29 to move upward and stretch the tension spring 30. Continuing to move can drive the pressure plate 28 to move on the connecting plate 8 until one side of the insert block 27 contacts the corresponding box 9.

[0048] The third motor 25 is then started to drive the second screw 23 to rotate, which in turn drives the insert block 27 to move. The insert block 27 can be inserted into the corresponding insert strip 38. At the same time, the insert block 27 can also drive the corresponding second pin 37 to move downward. The downward movement of the second pin 37 can drive the lifting plate 42 to move downward. The downward movement of the lifting plate 42 can drive the remaining second pins 37 to move downward, so that the second pins 37 are disengaged from the bottom of the box body 9. At the same time, it can drive the pressure plate 28 to move into the rectangular opening 33. At this time, the sliding column 29 can move downward under the force of the tension spring 30, which can drive the pressure plate 28 to move downward. The downward movement of the pressure plate 28 can drive the first pin 32 to be inserted into the corresponding positioning hole 36 to fix the box body 9.

[0049] Then, the first motor 11 is started to rotate in the opposite direction, which drives the first slider 3 to move in the opposite direction. This can drive the box 9 to detach from the corresponding support seat 39 until the box 9 is moved above the fire source. The air pumps in the first and second accommodating chambers 46 and 47 are started to pressurize the air, so that the extinguishing agent and water inside are sprayed out through the nozzle 35 to extinguish the fire source.

[0050] When the spray position needs to be adjusted, the second motor 16 is started to drive the first screw 15 to rotate. The rotation of the first screw 15 can drive the second slider 4 to move closer to the first slider 3. During the process of moving closer, the nut ring 21 can move closer to the first sliding ring 17, and the sliding block 22 can slide in the groove 26, which can cause one end of the support frame 18 to tilt downward, thereby adjusting the spray position.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
