Description

Technical Field

[0001] This utility model belongs to the field of tunnel safety protection technology, and relates to an intelligent turbulence device for attenuating shock waves. Background Technology

[0002] With the improvement of the accuracy and power of precision-guided weapons, when a large number of weapons and munitions explode at the entrance of a shelter, the resulting high-intensity blast shockwave enters the shelter through the tunnel, posing a great threat to the facilities and personnel inside. Due to the constraint of the tunnel walls, the pressure of the blast shockwave inside the tunnel decays more slowly and lasts for a longer period, making the destructive effect of the blast shockwave in the tunnel much greater than in an open space.

[0003] Built-in spoilers in tunnels can effectively improve the attenuation efficiency of shock wave overpressure peaks. The attenuation efficiency is particularly improved as the area of ​​the spoiler's wave-facing surface increases. However, if the wave-facing area of ​​the spoiler is too large, it will affect normal commuting within the tunnel.

[0004] Therefore, there is an urgent need for an intelligent turbulence device for attenuating shock waves. Utility Model Content

[0005] In view of this, the present invention provides an intelligent turbulence device for attenuating shock waves to solve the problems mentioned in the background art, and specifically discloses the following:

[0006] A smart flow-disrupting device for attenuating shock waves includes a flow-disrupting fixing plate, a flow-disrupting plate, a driving assembly, a support assembly, and a driving fixing plate. The flow-disrupting fixing plate and the driving fixing plate are sequentially fixedly installed in each fixing plate groove on the sidewall of the tunnel. The flow-disrupting fixing plate is close to the tunnel opening. The flow-disrupting plate is hinged to the flow-disrupting fixing plate via a rotating assembly. The driving assembly is fixedly disposed on the driving fixing plate and is used to drive the flow-disrupting plate to rotate, thereby opening and closing the flow-disrupting plate. One end of the support assembly is installed on the driving fixing plate, and the other end is rotatably connected to the back wave surface of the flow-disrupting plate near the driving assembly.

[0007] The wave-facing surface of the spoiler is provided with stress-strain strips;

[0008] The spoiler plate has a first reserved hole for installing a pressure sensor.

[0009] Furthermore, the rotating assembly includes a torsion spring support, a connecting nut, a washer, a rotating shaft, and a reset torsion spring. The torsion spring support is fixedly mounted on the spoiler fixing plate via the connecting nut and the washer. A rotating connecting seat is fixedly provided on the back wave surface of the spoiler away from the driving assembly. The torsion spring support is rotatably connected to the rotating connecting seat via the rotating shaft. The reset torsion spring is limited to the rotating shaft by the connecting nut. One end of the reset torsion spring is fixedly connected to the spoiler, and the other end is fixedly connected to the torsion spring support.

[0010] Furthermore, the drive assembly includes a stepper motor and an electric cylinder that are fixedly connected to the drive mounting plate in sequence. The stepper motor is used to drive the output end of the electric cylinder to extend and retract. The output end of the electric cylinder is fixedly connected to a drive rod. A drive connecting block is fixedly provided on the back wave surface of the spoiler near the drive assembly. The drive connecting block is provided with a through hole that is adapted to the drive rod.

[0011] The spoiler fixing plate is also provided with a positioning fixing seat. The positioning fixing seat has a positioning hole on the side near the drive rod that is adapted to the end of the drive rod. When the drive rod passes through the through hole and extends into the positioning hole, it fixes the spoiler and puts the spoiler in a closed state.

[0012] Furthermore, the drive fixing plate is provided with a drive guide seat near the alignment fixing seat, and the drive guide seat is provided with a drive guide hole that is adapted to the drive rod.

[0013] Furthermore, the support assembly includes a first crank arm connector, a second crank arm connector, a support bearing seat, and a support fixing plate. The support bearing seat is fixedly mounted on the drive fixing plate via the support fixing plate, and the crank arm bearing seat is fixedly mounted on the back wave surface of the spoiler near the drive assembly.

[0014] One end of the first crank arm connector is rotatably connected to the crank arm bearing seat, and the other end is rotatably connected to the second crank arm connector.

[0015] The end of the second crank arm connector away from the first crank arm connector is rotatably connected to the support bearing seat.

[0016] Furthermore, when the spoiler is deployed, the first crank arm connector and the second crank arm connector are collinear to support the spoiler and transfer the shock wave pressure of the spoiler.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention can intelligently control the opening and closing of the spoiler. Under normal conditions, the spoiler can be retracted and hidden in the side wall of the tunnel to ensure that the original function of the tunnel is not interfered with. In special circumstances, the spoiler can be quickly opened to realize the function of wave damping and disturbance, thereby protecting the tunnel and attenuating the shock wave of an explosion.

[0057] A smart turbulence method for attenuating shock waves, comprising the following steps:

[0058] S1: The trigger source component receives the signal and feeds it back to the main control circuit;

[0059] S2: The main control circuit sends a control signal to control the stepper motor 16 to move;

[0060] S3: Electric cylinder 18 drives drive rod 19 to retract, opening spoiler 7.

[0061] Furthermore, the trigger source component in step S1 includes three types of trigger source units that operate in parallel. The first type of trigger source unit is a radio frequency remote controller, and the warning signal is emitted by the control room via wireless remote control. The second type of trigger source unit is a radar warning system, and the warning signal is emitted by the communication circuit of the radar warning system. The third type of trigger source unit is a sound sensor and a vibration sensor, and the warning signal is emitted by the sound and vibration caused by the explosion of the explosive.

[0062] In this embodiment, the three trigger source units operate in parallel, all capable of feeding signals back to the main control circuit. Furthermore, the main control circuit should also be connected to an alarm component; when the spoiler 7 is opened, it controls the alarm light to illuminate and the alarm to sound, serving as a warning to personnel. The main control circuit uses an STM32F1 series microcontroller as the main control chip. Considering the existing power supply within tunnel 100 and potential damage to wartime circuits, it is designed with both 220V AC mains power and 24V battery power.
