Description

Technical Field

[0001] The present invention relates to the technical field of tunnel safety, and in particular to a shaft smoke exhaust and smoke penetration suppression device based on feedback regulation. Background Art

[0002] Tunnels are structures constructed underground, in mountainous areas, or underwater. They are equipped with smoke exhaust systems to expel smoke as quickly as possible in the event of a fire. To ensure rapid smoke exhaust in the event of a fire, reduce smoke concentration and heat, and protect the safety of tunnel occupants, shallow urban tunnels are typically equipped with longitudinal, transverse, and semi-transverse ventilation and smoke exhaust systems.

[0003] Shallow urban tunnels that utilize vertical shafts for ventilation and smoke exhaust face a significant challenge: air aspiration. When this occurs, cold air from the lower tunnel is drawn directly into the shaft, significantly reducing the shaft's smoke extraction efficiency and preventing the timely removal of smoke to protect trapped personnel. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a shaft smoke exhaust and smoke penetration suppression device based on feedback regulation.

[0005] The present invention is realized through the following technical solutions: a vertical shaft smoke exhaust and suction penetration suppression device based on feedback regulation, including a slide rail frame, an adjustment plate, a sensor and a control module, characterized in that: the slide rail frame includes a horizontal slide rail and a vertical slide rail, the horizontal slide rail is arranged in the vertical shaft, and the vertical slide rail is suspended below the horizontal slide rail. Under the drive of the first drive motor, the vertical slide rail can move back and forth along the axis of the horizontal slide rail. The adjustment plate is installed on the vertical slide rail. Under the drive of the second drive motor, the adjustment plate can move up and down along the vertical slide rail. The adjustment plate is a rectangular flat plate. The shape of the adjustment plate is adjusted by the third drive motor. The sensor, the first drive motor, the second drive motor and the third drive motor are all electrically connected to the control module.

[0006] As a further improvement to the above solution, the bottom end of the vertical slide rail extends out of the shaft opening.

[0007] As a further improvement to the above solution, the sensor includes a temperature sensor, and a plurality of temperature sensors are provided and respectively arranged at the shaft opening and the top of the bracket to form an array.

[0008] The present invention also provides a method for using a vertical shaft smoke exhaust and smoke penetration suppression device based on feedback regulation, which is characterized in that: when the temperature T1 collected by the temperature sensor at the top of the bracket is higher than the preset temperature T0, the control module will send an instruction to the second drive motor to move the adjustment plate downward until T1=T0; conversely, when T1 is lower than T0, the control module will send an instruction to the second drive motor to move the adjustment plate upward until T1=T0; when the temperature T2 collected by the temperature sensor at the wellhead is higher than T0, the control module will send an instruction to the third drive motor to increase the inclination angle of the adjustment plate to the horizontal plane, otherwise decrease it; when the temperature collected by the left temperature sensor at the wellhead is higher than the temperature collected by the right temperature sensor, the control module will send an instruction to the first drive motor to move the adjustment plate to the right, otherwise move it to the left.

[0009] Compared with the existing technology, the present invention has the following advantages: it provides multiple feedback systems, which is more energy-saving and environmentally friendly than before; the suction penetration suppression device is more intelligent and has a wide range of movement. It can achieve the best effect according to the actual fire situation to ensure that the efficiency of natural smoke exhaust in the vertical shaft is always maintained at a high level, further ensuring the life safety of people trapped inside after the fire occurs and the favorable development of rescue work, which will play an extremely important role in improving the effect of natural smoke exhaust in the vertical shaft.

[0013] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.

[0014] Example 1

[0015] The shaft smoke exhaust and air-inhalation suppression device based on feedback regulation includes a slide rail frame, an adjustment plate 5, a sensor and a control module 6, and is characterized in that: the slide rail frame includes a horizontal slide rail 2 and a vertical slide rail 4, the horizontal slide rail 2 is arranged in the shaft, and the vertical slide rail 4 is suspended below the horizontal slide rail 2. Under the drive of the first drive motor 1, the vertical slide rail 4 can move forward and backward along the axis of the horizontal slide rail 2, and the adjustment plate 5 is installed on the vertical slide rail 4. Under the drive of the second drive motor 3, the adjustment plate 5 can move up and down along the vertical slide rail 4. The adjustment plate 5 is a rectangular flat plate, and the shape of the adjustment plate 5 is adjusted by the third drive motor 7. The sensor, the first drive motor 1, the second drive motor 3 and the third drive motor 7 are all electrically connected to the control module 6. By arranging the adjustment plate 5 in the shaft, the air-inhalation problem of the natural smoke exhaust in the shaft can be suppressed. At the same time, the adjustment plate 5 can be moved up and down, left and right, and can change its posture through the slide rail frame, which can effectively respond to different situations to suppress air-inhalation. The adjustment plate 5 is arranged in the shaft, which will not affect the normal shape of the shaft and has little effect on the traffic function of the tunnel.

[0016] The feedback-regulated vertical shaft smoke exhaust device for suppressing smoke penetration, as claimed in claim 1, is characterized in that the bottom end of the vertical slide rail 4 extends beyond the shaft opening. This design allows the adjustment plate 5 to move outside the shaft opening in extreme circumstances, interfering with the flow of smoke and effectively suppressing smoke penetration.

[0017] The feedback-regulated shaft smoke exhaust device for suppressing smoke penetration according to claim 1 is characterized in that the sensor includes a temperature sensor 8, wherein a plurality of temperature sensors 8 are provided and arranged at the shaft head and at the top of the support to form an array. The arrayed temperature sensors 8 can effectively measure the temperature field distribution at the shaft head, thereby analyzing whether smoke penetration has occurred or is about to occur, and thus timely adjusting the position and configuration of the regulating plate 5.

[0018] Example 2

[0019] The method for using the vertical shaft smoke exhaust and smoke penetration suppression device based on feedback regulation as claimed in claim 1 is characterized in that: when the temperature T1 collected by the temperature sensor at the top of the bracket is higher than the preset temperature T0, the control module 6 will send an instruction to the second drive motor 3 to move the adjustment plate 5 downward until T1=T0; conversely, when T1 is lower than T0, the control module 6 will send an instruction to the second drive motor 3 to move the adjustment plate 5 upward until T1=T0; when the temperature T2 collected by the temperature sensor 8 at the wellhead is higher than T0, the control module 6 will send an instruction to the third drive motor 7 to increase the inclination angle of the adjustment plate 5 with the horizontal plane, otherwise decrease it; when the temperature collected by the left temperature sensor at the wellhead is higher than the temperature collected on the right side, the control module 6 will send an instruction to the first drive motor 1 to move the adjustment plate 5 to the right, otherwise move it to the left.

[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
