Description

Technical Field

[0001] The present invention relates to the technical field of tunnel safety, and particularly to a self-luminous emergency induction equipment for tunnels. Background Art

[0002] As a special section of high-grade highways, highway tunnels have the characteristics of extremely large brightness differences inside and outside the tunnel, serious air pollution, relatively small lateral clear widths and limited heights, and high noise. Coupled with the increasing number of vehicles in recent years, the advantages of high-grade highways are reduced, and traffic safety issues are prominent. If power outages, power maintenance, fire outages, etc. occur in the tunnel, if effective escape, rescue, indication and other disposal measures cannot be taken in time, secondary accidents are extremely likely to occur, possibly causing more significant property losses and social impacts.

[0003] Under the above working conditions, traditional emergency induction and indication equipment will completely lose brightness in the tunnel environment, greatly reducing the indication and escape functions, and cannot indicate pedestrians and induce vehicles to quickly leave or enter emergency channels such as vehicle lanes and pedestrian lanes for temporary evacuation when emergencies occur in the tunnel. Therefore, there is a need for an emergency induction equipment that can self-luminate for a long time after a power outage in the tunnel to improve the safety emergency guarantee ability of the tunnel.

[0004] At present, a relatively mature research system and application cases have been formed for self-luminous materials, and there are also various self-luminous materials with long afterglow times. How to better play the emergency guarantee effect when applied to emergency induction devices is a problem that needs to be solved at present. Summary of the Invention

[0005] The technical problem to be solved by the present invention is, in view of the above-mentioned existing technical deficiencies, to provide a self-luminous emergency induction equipment for tunnels, which can improve the emergency induction effect and can urgently change the emergency induction direction according to needs.

[0006] The technical solution adopted by the present invention is: to provide a self-luminous emergency induction equipment for tunnels, including a plurality of induction components arranged in sequence along the length direction of the tunnel, and power supply and sensing components respectively arranged at both ends of the tunnel;

[0007] The induction component includes a bottom box fixed on the inner wall of the tunnel, and a cover plate is hermetically connected to the bottom box correspondingly; the length direction of the bottom box is arranged along the length direction of the tunnel; an induction strip is fixed inside the bottom box along the length direction correspondingly; a number of pointing members are distributed along the length direction on the induction strip; the positions of the cover plate corresponding to the induction strip and the pointing members are transparent structures;

[0008] The pointing member described above includes guiding bars respectively arranged at both ends in the width direction of the guiding strip; one end of the guiding bar close to the guiding strip is connected to the guiding strip through a hinge; energy storage self-luminous coatings are respectively coated on the surfaces of the guiding strip and the guiding bar; the guiding bars on both sides in the width direction of the guiding strip are respectively controlled by a pushing member;

[0009] The pushing member described above includes a control rod parallel to the guiding strip; the control rod is slidably connected in the bottom box along the length direction; grooves corresponding to the guiding bars one by one are formed on the control rod; the sliding of the control rod is used to push the guiding bar to rotate hingedly; both ends in the length direction of the control rod are made of ferromagnetic materials; electromagnets are respectively fixed at the positions of the bottom box corresponding to both ends of the control rod; the electromagnets are used to attract the control rod to slide;

[0010] The power supply and sensing assembly described above includes a pressure-bearing rubber strip embedded in the road surface at the tunnel entrance; the pressure-bearing rubber strip is arranged along the width direction of the road surface; a plurality of piezoelectric blocks are wrapped inside the pressure-bearing rubber strip; two rows of pressure sensors for identifying the traffic flow direction are also wrapped inside the pressure-bearing rubber strip; the two rows of pressure sensors are respectively on both sides in the width direction of the pressure-bearing rubber strip; the piezoelectric blocks supply power to the electromagnets through a control circuit; the pressure sensors are connected to the control circuit, and the on-off of the electromagnets is controlled by a central processing unit in the control circuit.

[0011] To further optimize the technical solution, a supplementary light is fixed along the length direction on the bottom box of a self-luminous emergency guiding device for tunnels; the supplementary light penetrates outside the cover plate.

[0012] To further optimize the technical solution, a reflective layer is correspondingly covered on the outer surface of the cover plate of a self-luminous emergency guiding device for tunnels.

[0013] To further optimize the technical solution, a slide rail is fixed along the length direction inside the bottom box of a self-luminous emergency guiding device for tunnels; the control rod is slidably connected to the slide rail; a lubricant is coated on the slide rail.

[0014] To further optimize the technical solution, the electromagnet of a self-luminous emergency guiding device for tunnels is of an annular structure; a permanent magnet is fixed in the middle of the electromagnet; the magnetic force of the permanent magnet is weaker than that of the electromagnet at the far end.

[0015] To further optimize the technical solution, an indication mark for indicating the installation direction of the bottom box is provided on the cover plate of a self-luminous emergency guiding device for tunnels.

[0016] The beneficial effects of the present invention are as follows:

[0017] The control rod slides by the magnetic attraction of the electromagnet on the end of the control rod. The sliding of the control rod causes the groove to push the guide bar to rotate hingedly. Through the same-direction movement of the control rods on both sides, all the pointing members can form an arrow-type indication state with the same orientation. Combined with the energy-storing self-luminous coating on the surface of the induction strip and the guide strip, it can provide clear direction induction for the vehicles in the tunnel; the energy-storing self-luminous coating absorbs and stores light energy by itself, and can, through the self-luminous effect, ensure the emergency induction guarantee ability after the tunnel power failure.

[0018] Electromagnets are respectively fixed at both ends of the bottom box corresponding to both ends of the control rod. When different electromagnets are energized and work, they can drive the control rod to slide in different directions, playing a role in changing the indication orientation of the pointing member, and improving the functional richness of emergency induction in an emergency state.

[0019] The piezoelectric blocks in the pressure-bearing rubber strip can convert the pressure generated when the vehicle passes by into electric power to provide electric power for the work of the electromagnet, effectively saving energy; the two rows of pressure sensors can detect the direction of the vehicle's travel by detecting the sequence of the triggered pressures when the vehicle passes by, and based on this, control which end of the electromagnet is energized through the control circuit to ensure that the direction indicated by the pointing member is consistent with the vehicle's travel direction.

Detailed Embodiment

[0026] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0027] As Figure 1 shown, a self-luminous emergency induction device for a tunnel includes a plurality of induction assemblies arranged in sequence along the length direction of the tunnel, and power supply and sensing assemblies respectively arranged at both ends of the tunnel.

[0028] As shown Figure 2 in the figure, the induction component includes a bottom box 1 fixed on the inner wall of the tunnel, and a cover plate 2 is hermetically connected to the bottom box 1 correspondingly; the length direction of the bottom box 1 is arranged along the length direction of the tunnel; an induction strip 3 is fixedly arranged inside the bottom box 1 along the length direction; a number of pointing members are distributed along the length direction on the induction strip 3; the positions of the cover plate 2 corresponding to the induction strip 3 and the pointing members are of a transparent structure;

[0029] As shown Figure 2-3 in the figure, the pointing member includes guiding strips 4 respectively arranged at both ends in the width direction of the induction strip 3; one end of the guiding strip 4 close to the induction strip 3 is hinged to the induction strip 3; energy storage self-luminous coatings are respectively coated on the surfaces of the induction strip 3 and the guiding strip 4; the guiding strips 4 on both sides in the width direction of the induction strip 3 are respectively controlled by a pushing member. The energy storage self-luminous coating absorbs and stores light energy by itself, and can ensure the emergency induction guarantee ability through the self-luminous effect after the tunnel power failure. Through the self-luminous indication on the surfaces of the pointing member and the induction strip 3, it can effectively guide the movement of people and vehicles in a harsh environment. The energy storage self-luminous coating can be specifically selected according to requirements, such as aluminate-based long afterglow materials, calcium aluminate modified materials, etc. Since there are relatively mature products on the market, they will not be elaborated here.

[0030] As shown Figure 3 in the figure, the pushing member includes a control rod 5 parallel to the induction strip 3; the control rod 5 is slidably connected in the bottom box 1 along the length direction; grooves 6 corresponding to the guiding strips 4 one by one are formed on the control rod 5; the sliding of the control rod 5 is used to push the guiding strip 4 to rotate hingedly; both ends in the length direction of the control rod 5 are made of ferromagnetic materials; electromagnets 7 are respectively fixed at the positions of the bottom box 1 corresponding to both ends of the control rod 5; the electromagnet 7 is used to attract the control rod 5 to slide;

[0031] As shown Figure 1 , Figure 4 , Figure 5 in the figure, the power supply and sensing component includes a pressure-bearing rubber strip 8 embedded on the road surface at the tunnel entrance; the pressure-bearing rubber strip 8 is arranged along the width direction of the road surface; a plurality of piezoelectric blocks 9 are wrapped inside the pressure-bearing rubber strip 8; two rows of pressure sensors 10 for identifying the traffic flow direction are also wrapped inside the pressure-bearing rubber strip 8; the two rows of pressure sensors 10 are respectively on both sides in the width direction of the pressure-bearing rubber strip 8; the piezoelectric block 9 supplies power to the electromagnet 7 through a control circuit; the pressure sensor 10 is connected to the control circuit, and the energization and de-energization of the electromagnet 7 are controlled by a central processor in the control circuit. The pressure-bearing rubber strip 8 can not only buffer the pressure impact and provide protection for the piezoelectric block 9 and the pressure sensor 10, but also reduce the impact on vehicle driving. According to requirements, the pressure-bearing rubber strip 8 only needs to be slightly higher than the road surface to ensure that the wheels can roll over it.

[0032] The induction components are arranged on the inner wall of the tunnel according to a preset unified orientation. After the electromagnets 7 at the same end of the bottom box 1 are energized and work, they attract the control rod 5 to slide, and the groove 6 pushes the guide bar 4 to rotate hingedly, so that all the pointing members can form an arrow-type indication state with the same orientation, as Figure 2 shown. At this time, the direction pointed by the pointing member is the emergency induction direction, that is, the direction for vehicles or pedestrians to pass through.

[0033] Compared with the traditional emergency induction device with fixed pointing, the pointing in this solution can be reversed. Just control the electromagnets 7 at different ends to be energized, so that the control rod 5 slides in the reverse direction, and the groove 6 can push the pointing member to form a reverse arrow indication state. The reason for such a setting is that in some emergency situations, such as tunnel accidents, natural disasters, bad weather conditions, etc., it may be required that the vehicles in the tunnel drive out of the tunnel in the reverse direction. At this time, the emergency induction direction needs to be opposite to the normal direction to provide emergency escape guidance for the people in the tunnel.

[0034] To achieve the above switching, a power supply sensing component is set in this solution. On the one hand, it supplies power to the electromagnet 7 through the piezoelectric effect of the piezoelectric block 9, and on the other hand, it identifies which end of the electromagnet 7 needs to be powered through the pressure sensor 10.

[0035] When the vehicle drives over the pressure rubber strip 8 on the road surface at the tunnel entrance, both the pressure sensor 10 and the piezoelectric block 9 are subjected to pressure.

[0036] The piezoelectric block 9 can adopt materials such as piezoelectric crystals, piezoelectric ceramics, and piezoelectric polymers, convert the pressure generated by the vehicle driving into electricity, and control the electricity to supply power to the electromagnet 7 through the control circuit, so that the electromagnet 7 does not require external independent power supply, effectively saving energy, and effectively avoiding the problem that the device cannot be used due to the failure of the external power supply system, ensuring the reliability of the emergency guarantee.

[0037] The two rows of pressure sensors 10 detect the direction of the vehicle driving by detecting the sequence of the pressures triggered when the vehicle passes, and based on this, control which end of the electromagnet 7 is energized through the control circuit to ensure that the direction indicated by the pointing member is consistent with the vehicle driving direction.

[0038] When an emergency occurs and the vehicle drives out of the tunnel in the reverse direction, the pressure sensor 10 detects the change in the vehicle direction, and the central processor in the control circuit will control the electromagnet 7 at the other end to be energized, and the previous electromagnet 7 is powered off. At this time, the control rod 5 slides reversely to the other end, and the pointing member can be reversed.

[0039] Of course, sometimes vehicles that do not follow the rules and drive in the opposite direction in the tunnel may be encountered. At this time, the original pointing of the pointing member needs to be maintained. For this purpose, the central processing unit in the control circuit can set a trigger logic for controlling the energization switching of the electromagnet 7. For example, when the sequence of the pressure sensors 10 in a certain area sensing the passing of a vehicle is inconsistent with that of the pressure sensors 10 in other areas, it means that there are vehicles driving in the opposite direction among the vehicles in the normal driving direction. Since the number of vehicles driving in the opposite direction is small (usually one vehicle driving in the opposite direction within the same time period), so following the "majority principle" at this time, the energization and de-energization of the electromagnet 7 are still controlled by the sequence of pressures detected by the majority of the pressure sensors 10, ensuring the reliability of the operation of this device.

[0040] A supplementary light 11 is fixed along the length direction on the upper edge of the bottom box 1; the supplementary light 11 penetrates outside the cover plate 2. On the one hand, the supplementary light 11 can improve the guiding ability by emitting light itself in the case of low air visibility. On the other hand, it can also provide light energy for the energy storage self-luminous coating so that it can absorb and store light energy in a timely manner. The supplementary light 11 can be set to turn on every once in a while according to requirements, or the turning-on time can be controlled according to the recognized external brightness situation.

[0041] A reflective layer is correspondingly covered on the outer surface of the cover plate 2. When the vehicle's driving headlights shine, it can reflect light, effectively guiding the tunnel direction.

[0042] A slide rail 12 is fixed along the length direction inside the bottom box 1; the control rod 5 is slidably connected to the slide rail 12; a lubricant is coated on the slide rail 12. The sliding of the control rod 5 reduces friction, making the adsorption of the electromagnet 7 on it smoother.

[0043] The electromagnet 7 is of a ring structure; a permanent magnet block 13 is fixed in the middle of the electromagnet 7; the magnetic force of the permanent magnet block 13 is weaker than the magnetic force of the distal electromagnet 7. After the electromagnet 7 magnetically attracts the control rod 5, in order to save energy, the electromagnet 7 can be set to cut off the power after a period of time, and the magnetic adsorption connection of the permanent magnet block 13 is used to maintain the position of the control bar. The magnetic property of the permanent magnet block 13 is set to be weak to ensure that when the control rod 5 needs to move in the reverse direction, the magnetic force of the distal electromagnet 7 can overcome the magnetic force of the permanent magnet block 13 at this time.

[0044] An indication mark 14 for indicating the installation direction of the bottom box 1 is provided on the cover plate 2. The function of the indication mark 14 is to ensure the accurate direction of the initial installation of the induction component in the tunnel.

[0045] It will be understood that the present invention is described by way of some embodiments, and those skilled in the art will know that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. Additionally, under the teaching of the present invention, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
