Abstract
Description
Technical Field
[0001] The present invention relates to a safety control device and method for tunnel traffic under extreme conditions, in particular to a powerless intelligent control device and method for tunnel traffic flooded by rainwater, belonging to the technical field of traffic control. Background Art
[0002] At present, with the development of my country's economy, more and more three-dimensional traffic roads are being built. Many three-dimensional traffic roads have sunken tunnels. Since the elevation of sunken tunnels is lower than that of normal roads, when extreme weather occurs or nearby pre-buried water pipes rupture, rainwater will flow into the tunnels, hindering traffic and failing to ensure the safe passage of vehicles and pedestrians. If the tunnel entrance cannot be closed in time, disastrous consequences will occur. At present, there are two main types of traffic control in such tunnels: one is controlled by an electric system (sensor, circuit, controller, electric gate); the other is controlled by manual mobile roadblocks. Both methods have serious problems: when power is lost in extreme weather or when a large amount of water suddenly enters the tunnel at night, it is impossible to control tunnel traffic in a timely and effective manner. Summary of the invention
[0003] The purpose of the present invention is to provide a new method for timely, effective, convenient and fast control of tunnel traffic when there is no electricity due to rainwater flooding, that is, an intelligent control device and method for tunnel traffic when there is no electricity due to rainwater flooding. The present invention is easy and quick to install and use.
[0004] The objective of the present invention is achieved through the following technical solutions:
[0005] The first object of the present invention is to provide a non-electric intelligent control device for tunnel traffic flooding due to rainwater, which is characterized by comprising an intelligent flooding depth detection system arranged in a sunken tunnel, an intelligent control system arranged at the tunnel entrance, a traffic control gate rod controlled by the intelligent control system, and a double-connected pneumatic tube connecting the intelligent flooding depth detection system and the intelligent control system; the intelligent flooding depth detection system comprises a flooding depth sensing air pressure barrel arranged in a tunnel water collection tank; the intelligent control system comprises a float, a float connecting rod, a steering connector, a flooding depth crossing sensing converter box, and a gate control box at the tunnel entrance;
[0006] The tunnel sump is arranged at the bottom of the sunken tunnel pavement and corresponds to the low-lying position of the sunken tunnel pavement; the submerged water depth sensing air pressure barrel is fixed to the inner wall of the tunnel sump, with its barrel mouth facing downward so as to be submerged in the water of the tunnel sump; the end of the traffic control barrier pole is hinged to the barrier control box, the submerged depth crossing sensing converter box is fixed in the barrier control box, the float floats on the liquid in the submerged depth crossing sensing converter box, the top of the float is connected to the float connecting rod, the middle position of the steering connecting piece is fixed to the inner wall of the barrier control box, and serves as the fulcrum of the steering connecting piece, and its two ends are respectively hinged to the ends of the float connecting rod and the traffic control barrier pole; the two ends of the double-connected pneumatic tube are respectively connected to the top of the submerged depth crossing sensing converter box and the top of the submerged water depth sensing air pressure barrel.
[0007] Preferably, the intelligent control system also includes a level crossing intelligent sensing float positioning barrel, which is fixed in the submerged depth level crossing sensing converter box, and a gap is left between the bottom of the level crossing intelligent sensing float positioning barrel and the bottom of the submerged depth level crossing sensing converter box, the float is placed in the level crossing intelligent sensing float positioning barrel, and the double-connected pneumatic tube is connected to the top of the level crossing intelligent sensing float positioning barrel.
[0008] Preferably, the steering connector is formed by connecting a straight rod and an arc-shaped rod, and the connection point between the straight rod and the arc-shaped rod is the fulcrum of the steering connector.
[0009] The second object of the present invention is to provide a non-electric intelligent control method for tunnel traffic flooding due to rainwater, which is characterized in that when the accumulated water in the tunnel forms a falling water body through the inlet of the sunken tunnel drainage sump and falls into the tunnel sump, the water level in the tunnel sump rises, and the air pressure in the flooding depth sensing air pressure barrel fixed on the inner wall of the tunnel sump increases, and the pressure is transmitted to the gate control box at the tunnel entrance through the double-connected pneumatic tube;
[0010] When the liquid in the submerged depth crossing sensing converter box is under the action of air pressure, the water level in the crossing intelligent sensing float positioning bucket fixed in the submerged depth crossing sensing converter box rises, and the float pushes the float connecting rod to rise. Then, using the lever principle, the steering connector pushes the traffic control gate rod down to control the traffic closure of the tunnel entrance.
[0011] On the contrary, the water level in the sump drops, the air pressure decreases, the float falls, the gate pole automatically rises, and the tunnel entrance control is opened.
[0012] The present invention relates to how to control traffic in time when rainwater floods a traffic tunnel to ensure the safety of people's lives and property. The device of the present invention is divided into three parts, namely, the intelligent detection and flooding depth system part (installed in the lowest part of the tunnel), the early warning intelligent control part (at the entrance of the tunnel) and the connection part (double pneumatic tube). This method is simple and real-time, easy to control, and does not require power. It not only meets the control requirements of urban road tunnels, but also meets the control requirements of sunken roads in remote areas. Specifically, it has the following advantages:

DETAILED DESCRIPTION
[0021] Figure 1 The figure shows a cross-sectional view of a non-electric intelligent control (device) when tunnel traffic is flooded by rainwater. In the sunken tunnel 1 below the upper road 4 of the tunnel, an intelligent flooding depth detection system 2 is installed in the low-lying water collection pool. The flooding situation is transmitted to the intelligent control system part 5 at the tunnel entrance through the double-connected pneumatic tube 3, and the tunnel traffic is controlled according to the flooding depth. When the water depth in the tunnel cannot meet the requirements for safe passage, the gate at the entrance is automatically lowered to prohibit vehicles from entering.
[0022] Specifically, Figure 2 It is a structural diagram of the intelligent submergence depth detection system part 2. A tunnel water collection pool 6 is provided below the sunken tunnel pavement 12 (off the edge of the road). The submerged water depth sensing air pressure barrel 7 is fixed on the wall of the water collection pool 6 at an appropriate height (the height can be simply adjusted) through the submerged water depth sensing air pressure barrel fixing device 9 in the pool. When working, the lower opening of the submerged water depth sensing air pressure barrel 7 is submerged in the water 8 in the water collection pool, and the double-connected pneumatic tube 3 is connected to the top of the submerged water depth sensing air pressure barrel 7 through the submerged water depth sensing air pressure barrel pneumatic tube connector 10. When the tunnel water forms a falling water body 11 through the inlet 13 of the sunken tunnel drainage water collection pool and falls into the water collection pool, the water level in the water collection pool 6 rises, and the air pressure in the submerged water depth sensing air pressure barrel 7 fixed on the wall of the pool increases; its pressure is transmitted to the tunnel entrance gate control box 20 of the intelligent control system part 5 at the tunnel entrance through the double-connected pneumatic tube 3.
[0023] Figure 3This is the structure diagram of the traffic intelligent control system 5 (at the tunnel entrance). When the intelligent detection submergence depth system part 2 is transmitted to the submergence depth crossing sensing converter box 18 through the double-connected pneumatic tube 3 and the submergence depth crossing sensing converter pneumatic tube connector 24, the liquid 21 in the submergence depth crossing sensing converter box, under the action of air pressure, causes the water level in the crossing intelligent sensing float positioning barrel 23 fixed in the submergence depth crossing sensing converter box 18 through the crossing intelligent sensing float positioning barrel fixing device 19 to rise, and the float 22 pushes the float connecting rod 25 to rise. Afterwards, the steering connector 17, through the fulcrum 27 of the steering connector, the connecting hinge 26 of the float connecting rod and the steering connector, and the consolidation hinge 16 connecting the gate rod 14 and the steering connector, pushes the traffic control gate rod 14 installed on the tunnel entrance gate control box 20 through the gate rod rotating hinge 15 to lower, and the tunnel entrance is closed. In addition, the gate rod is made of lightweight material.
[0024] On the contrary, the water level in the water collection pool drops, the air pressure decreases, the float falls, the gate rod automatically rises, and the tunnel entrance control is opened. The whole process is fully automatic, without manpower and electricity, and intelligent control.
