Preferably, both the first jacking mechanism 26 and the second jacking mechanism 29 are hydraulic jacks.
When the smoke sensor 8, the temperature detector 9 or the inspection robot 10 detects that abnormality occurs, an electric signal is fed back to the control box 27, the system enters an emergency rescue state, the control box 27 automatically controls the combined actions of the movable curb 25, the first lifting mechanism 26, the invisible buried guardrail 28, the second lifting mechanism 29 and other structures according to a preset program to further ensure personnel safety and facilitate rescue, the sidewalk 3 is automatically blocked, the pedestrian is prevented from being mistakenly inserted to cause falling or affecting personnel escape in a pipe gallery, traffic is dredged, part of the curb is opened, the sidewalk 3 is used as a parking area of an emergency rescue vehicle, traffic is not blocked, and the emergency rescue process can be accelerated. In the process, as the pavement 3 and the curb are higher than the pavement 2 by a certain height, the emergency rescue vehicle is difficult to stop, traffic is blocked, even traffic jam is caused, the subsequent emergency rescue vehicle is difficult to reach the scene, the movable curb 25 with the top being an inclined plane descends by a certain height under the control of the hydraulic jack, as shown in fig. 8, the height difference between the pavement 2 and the pavement 3 is eliminated, and the emergency rescue vehicle can drive into the original pavement 3 to stop at the illustrated position for rescue.
In addition, when the smoke sensor 8, the temperature detector 9 or the inspection robot 10 does not detect that an abnormality occurs, the process can be manually controlled by an maintainer through a switch of the control box 27, namely, a feeding maintenance state is achieved, and the normal operation state is restored after the feeding maintenance is finished or the emergency rescue is finished.
In order to more clearly identify the state and the emergency state or the feeding maintenance state at night, the vehicle speed indicator 30, the state indicator 31 and the avoidance indicator 32 are arranged above the roadway 2, and the indication parts of the vehicle speed indicator 30, the state indicator 31 and the avoidance indicator 32 are realized by adopting LEDs with different colors, so that the energy can be saved and the control is convenient. The vehicle speed indicator 30 and the state indicator 31 are disposed on a front side of the transition switching chamber 11 in the vehicle flow direction, the avoidance indicator 32 is disposed on a rear side of the transition switching chamber 11 in the vehicle flow direction, and the vehicle speed indicator 30, the state indicator 31 and the avoidance indicator 32 respectively display vehicle speed limit information, utility tunnel state information and avoidance prompt information under the current condition according to control signals sent by the control box 27.
In the emergency state or the charging maintenance state, the parts which are significantly changed in the aspect of the roadway 2 are: the LED speed limit sign on the speed indicator 30 is changed to 40, and the vehicle is prompted to decelerate; the LED emergency rescue lamp plate on the state indication plate 31 is started to prompt that the rightmost lane is only used by an emergency rescue vehicle, so that the situation that a social vehicle enters by mistake is avoided; the LED on the avoidance indicating plate 32 enables a travel mark to prompt the social vehicle to avoid the exit of the emergency rescue lane.
Further, a first electronic ground sign 33 is disposed in the pavement 2, the first electronic ground sign 33 is disposed near the movable curb 25, a second electronic ground sign 34 is disposed in the pavement 3, the second electronic ground sign 34 is disposed on the outer side of the invisible buried guard rail 28, and the first electronic ground sign 33 and the second electronic ground sign 34 are both connected to a control signal output end group of the control box 27.
Specifically, in an emergency rescue state or a feeding maintenance state, an orange LED lane mark in the first electronic ground mark 33 is started to prompt a right lane to be an emergency rescue lane, so that the night emergency rescue vehicle can be conveniently identified; the LED red pedestrian traffic-prohibited mark in the second electronic ground mark 34 is started to prompt that the sidewalk 3 is in an emergency rescue state or a feeding maintenance state at the moment, and pedestrians are prohibited from traffic. In addition to this, the parts that are significantly changed in the sidewalk 3 are: the ground material inlet 17 and the ground entrance 18 are provided with an audible and visual alarm mechanism 35, the audible and visual alarm mechanism 35 is connected with a control signal output end group of the control box 27, and a warning lamp in the audible and visual alarm mechanism 35 flashes and a buzzer sends out an alarm sound signal to serve as an auxiliary measure for prompting pedestrians to stop advancing.
The specific working principle of the system is as follows:
the system has three operation states, namely a normal operation state, an emergency rescue state and a feeding overhaul state;
1. normal operation state
The speed indicator 30 displays the speed limit 80 (note: the sign should stand upright, no lane is occupied, the common expression method of the road map is the same in the figure), the status indicator 31 is closed, the avoidance indicator 32 is closed, the first electronic ground indicator 33 is closed, the second electronic ground indicator 34 is closed, the movable curb 25 is lifted, the invisible buried guard rail 28 falls down to be flush with the ground of the sidewalk 3, and the large feeding port 12, the small feeding port 13, the ground entrance 18, the audible and visual alarm mechanism 35 are all in the closed state, as shown in fig. 1 and 3;
2. emergency state of emergency
When the smoke sensor 8, the temperature detector 9 or the central control room detects that the inspection robot 10 detects abnormality, an electric signal is fed back to the control box 27, the system automatically enters an emergency state, and the control box 27 automatically sends out a control instruction to control the electric control executing mechanisms to execute corresponding actions, and the method specifically comprises the following steps: the two groups of first jacking mechanisms 26 are driven to drive the movable curbs 25 to descend by a certain height, so that the height difference between the pavement 2 and the sidewalk 3 is eliminated, an emergency rescue vehicle can drive into the sidewalk 3 to rescue and can drive out of the sidewalk 3 from the movable curbs 25 on the other side after rescue is completed; meanwhile, the second lifting mechanism 29 is driven to lift the invisible buried guardrail out of the ground to automatically block the sidewalk 3, so that pedestrians are prevented from advancing, and the pedestrians are prevented from falling or affecting escape of the personnel in the pipe gallery due to false entry; controlling the LED speed limit sign on the speed indicator 30 to be changed to 40; controlling the LED emergency light on the status indicator board 31 to be turned on; controlling LEDs on the avoidance indicators 32 to turn on a row mark; controlling the orange LED lane mark in the first electronic ground mark 33 to be turned on; controlling the LED red pedestrian traffic-prohibited mark in the second electronic ground mark 34 to be opened; the control unit controls the audible and visual alarm mechanism 35 to turn on and send out audible and visual prompt signals, as shown in fig. 7 and 8;
3. feeding overhauling state
The batch maintenance state differs from the emergency maintenance state only in that each emergency action in the emergency maintenance state is manually started by a worker through the inner tube of the control box 27. In addition, the cover plate 19 is opened, so that materials can enter and exit from overhaul equipment or materials under replacement through the ground feeding port 17 arranged on the outer side of the pavement 3 and the large feeding port 12, the small feeding port 13 and the feeding fishing ring 23 arranged in the transition switching chamber 11, and smoothness of vehicles on the ground pavement 2 is not influenced during overhaul of the comprehensive pipe rack.
Finally, after the emergency rescue state or the feeding maintenance state is finished, the staff manually controls the system to recover to the normal operation state through the control box 27.
The technical scheme provided by the invention is described in detail.
