Description

Tunnel entry blocking device {Tunnel entry blocking device}

The present invention relates to an entry blocking device that is installed on an access road such as a tunnel regardless of the season and automatically operates in the event of an emergency to prevent a vehicle from entering the tunnel. The present invention relates to a tunnel entry blocking device with improved accident recognition function capable of preventing deterioration of visibility by minimizing deformation due to distance and effectively preventing an abnormal entry attempt of a following vehicle in the event of a tunnel accident.

In general, tunnels are formed by penetrating obstacles such as mountains for rapid passage of highways, etc. These tunnels have the great advantage of shortening the driving time by minimizing the driving distance of a vehicle, but in the event of an accident in the tunnel There was a problem that was very difficult to deal with quickly.

In particular, if a fire accident occurs in a tunnel due to a traffic accident, vehicle fire, or electric leakage, there is a high risk of suffocation due to flame or smoke, and if the driver enters the tunnel without recognizing the tunnel accident, promptly There is a risk of large-scale human and material accidents due to lack of evacuation work.

Therefore, although an emergency means such as a fire extinguisher is provided in the tunnel, fire extinguishing is impossible due to the dark and narrow interior, and it is very difficult for a fire engine to enter the tunnel.

In addition, various sensors are installed and detected inside the tunnel at regular intervals, and the detected data is transmitted in real time to the tunnel equipment room and remote operation center, so that the manager can promptly notify the occurrence of an accident and take action. installed and running.

However, in the conventional tunnel entry blocking device, when the film body is unbalanced or an external force such as wind is applied in the process of winding or unwinding the film body as a whole on the rotating shaft, the film body is irregularly wound or unwound, resulting in frequent malfunctions there was

In addition, since the body part is fixedly installed on the entrance of the tunnel, when repairing the body part, workers or maintenance equipment must be located in the middle of the highway, so there is a risk of safety accident as well as a problem that provides a factor of traffic obstacle there was

In addition, there is a problem that the glass of the vehicle is frequently broken by a plurality of support rods installed in the warning unit at regular intervals.

And above all, all of the above-mentioned conventional technologies are manufactured without in-depth consideration of the characteristics of the installation point, so the above-described malfunction often occurs, especially in winter, and the visibility of the warning message is greatly reduced.

That is, in general, when rain or snow falls in the winter when the amount of sunlight is low, a freezing phenomenon immediately occurs at the entrance and exit of the tunnel, and a strong wind is also generated.

However, since all of the above-mentioned conventional technologies were manufactured without considering countermeasures against rain or snow, the equipment related to the drive is easily frozen when exposed to rain or snow, and the film body or blocking curtain with warning text printed and warning due to strong wind This is because the unit is made so that it cannot maintain its appearance.

In addition, in the case of the improved motorized tunnel entry device, as in the prior art, the H beam to which the barrier box is to be transported must be fixed and connected to the top of the horizontal bar of the circular support with welding and bolts, so manufacturing is not easy. There was a problem that it took a lot of time to manufacture without a problem, and there was also a structural problem that greatly increased the weight of the entire facility.

In addition, due to a structural problem that inevitably exposes a large amount of the chain that enables the transfer of the barrier box to the left and right, the chain needs to be periodically inspected and maintained, which is inconvenient and uneconomical in maintenance. .

In addition, measures to prevent accidents in tunnels and underpasses, such as accidents caused by unrecognized drivers entering the underpass due to natural disasters such as floods in the underpass in the city center, have recently been flooded with water. is in need.

Therefore, definitions of these terms will have to be made based on the content throughout this specification.

The tunnel entry blocking device of the present invention includes a vertical member 100 installed on both sides of the road and a horizontal member 200 connecting upper ends of both sides of the vertical member;

one or more rail brackets 220 installed to be movable left and right along the movable rail 210 installed to extend in the longitudinal direction of the horizontal member 200;

a guide roller 222 including a spring 221 connected to the rail bracket 220;

A protrusion 230 having an inclination angle formed on a part of the horizontal member 200;

an entry barrier 300 including one or more joints so that the protruding part of the guide roller 222 can be easily expanded and folded by an inclination angle and elasticity of a spring;

One or more blocking film enclosures 310 attached to the vertical member 100 to store the entry blocking film 300;

A warning means (500) installed on the horizontal member (200) to inform the prohibition of entry of vehicles entering in case of disaster risk;

a control unit 700 for controlling driving of the entry barrier 300, the warning means 500, and the rail bracket 220; The entry blocking device for the tunnel, soundproof tunnel and underpass will be described in detail below.

First, one or more rail brackets 220 installed in the longitudinal direction of the horizontal member 200 are moving rails made of a horizontal cylindrical shape (circular pipe) by one or more moving rollers 223 respectively attached to the upper and lower portions ( 210) and is composed of one or more moving rails 210 according to the width of the road to be blocked, so that when the rail bracket 220 completely enters the blocking film enclosure 310, one or more rail brackets 220 are shown in FIG. 9 As shown in , a plurality of rail brackets 220 are configured to have different heights and shapes so that they can be contacted with a minimum area, so that the area of the barrier enclosure 310 can be minimized.

Area minimization is to make the rail brackets 220 located in the middle of the plurality of rail brackets 220 lower than the rail brackets at the edges, so that when entering the barrier enclosure 310, the lower rail brackets 220 at the edges By entering and minimizing the area of the rail bracket, the area of the barrier enclosure was minimized.

In the present invention, one or more movable rollers 223 attached to each rail bracket 220 may be installed on the upper and lower portions of the plurality of movable rails 210 to ensure safety.

In addition, as shown in the detailed drawing of FIG. 5 and FIG. 9, the rail bracket 220 and the movable rail 210 are configured to increase according to the lane when the road width increases to more than one one-way lane, and three rail brackets Describing 220 as an embodiment, a rail bracket 220a moved from the movable rail 210a installed at the front end, a rail bracket 220a moved from the second movable rail 210b, and a third movable rail 210c. The rail brackets 220b and 220c that move along the rail move along different movable rails 210a, 210b and 210c and have different shapes, so that when stored in the shield box 310, the The volume was minimized. In addition, the rail bracket (220a), which is moved first, not only takes the most load, but also plays a role in leading the following rail brackets (220b, 220c) and maintains stability without shaking during movement. and the moving rail 210c at the rearmost end so that it can be moved using two moving rollers 223, respectively, and at the time when the entry barrier 300 is stored in the barrier enclosure 310, the limit switch The door of the enclosure 310 is automatically opened and closed, and when the width is very wide, one or more movements are made in the upper and lower portions in consideration of safety in each rail bracket 220 as well as the most leading rail bracket 220a as described above A roller 223 may be configured.

The above configuration reflects the center of gravity due to the weight of the access barrier when the rail bracket 220 is moved, which may cause a failure due to a high load on the moving roller 223 when the moving rail 210 moves. Therefore, it is possible to make a difference in the shape and driving method of the rail bracket.

In addition, it is fixedly installed in the form of covering the entry blocking film 300 on the square frame 320 made of metal or plastic connected to the lower part of the rail bracket 220 to prevent the entry blocking film 300 from fluttering in case of strong wind, and the entry blocking film 300 ) In the tail part 330 having a certain length at the bottom, an antifreeze bag 340 in which a bag injected with antifreeze can be placed so as not to freeze even in winter is configured to minimize the effect of wind while reducing the risk of vehicle damage in the event of a vehicle collision. wanted to prevent. In addition, the entrance barrier film 300 used in the present invention has a length of one side of the mesh of 10 mm or more and a fluorescent color character expression unit capable of recognizing a letter indicating entry blocking, so that the barrier film flutters or deforms due to strong wind. This was minimized and visibility was increased, and the square frame 320 installed on the entry barrier 300 was connected to the rail bracket 220 in the form of a space, so that it could act as a joint when unfolding and folding. In addition, inside the rail bracket 220, a guide roller 2220 is attached along with a spring 221 to a support bar 350 that rotates the square frame 320, and the inclination angle (step difference) formed in the horizontal member 200 is reduced. When passing through the protrusion 230, the square frame 320 rotates at an angle of 90° using the elasticity of the spring and the force of inertia according to the moving auto-reel of the rail bracket 220 so that it can be easily unfolded and folded. did

The spring 221 made of metal has the number of revolutions of the spring within the range of 6 ± 3 times so as to have elasticity capable of withstanding the force of inertia. If it is more than one time, elasticity is too strong, and a problem may occur in recovery during unfolding and folding. Of course, if a metal of an elastic material is used for elasticity, the number of revolutions can be changed.

In addition, the elasticity of the spring 221 changes over time due to the corrosion generated in the metal material, which can cause problems when folding and unfolding the barrier film. It was intended to maximize durability by having resistance.

The nano-inorganic coating can be used to prevent rust and corrosion of all metals used in the blocking device of the present invention as well as the spring, and the nano-inorganic material is,

It contains at least one of sodium oxide (Na ₂ O), potassium oxide (K ₂ O), and lithium oxide (Li ₂ O), which are alkali metal oxides (M ₂ O) represented by the following formula; inorganic acid compounds; and water (H ₂ O);

[Formula] (x ₁ Na ₂ O+x ₂ K ₂ O+x ₃ Li ₂ O)·ySiO ₂ ·nH ₂ O

x₂+x₃ ), y>=X를 만족한다.In the formula (x ₁ Na ₂ O+x ₂ K ₂ O+x ₃ Li ₂ O) ySiO ₂ , X>0, (X=x ₁ +x ₂ +x ₃ and x _1, x _2, x ₃ >=0, x ₁

x ₂ +x ₃ ), and y>=X.

In 100 parts by weight of the nano-inorganic material represented by the above formula ((x ₁ Na ₂ O+x ₂ K ₂ O+x ₃ Li ₂ O)·ySiO ₂ ·nH ₂ O), (M ₂ O+ySiO ₂ ) is 0.1 ~ 10 parts by weight and characterized in that it includes 0.01 to 2 parts by weight of an inorganic acid compound and the balance of water.

The composition represented by the above formula may further include a dispersant, a catalyst, and a surfactant according to the required functionality, coating method, and coating apparatus.

The change of the composition according to the coating device may vary depending on the pretreatment equipment, and in particular, a dispersant is used to improve adhesion characteristics by including a surfactant according to the hydrophilicity of the surface of the base material and to improve the dispersion of color pigments for color. It may be further included, and a catalyst may be further included to shorten the production time of the composition and promote chemical reactions.

In addition, in the present invention, when the access barriers 300 moving on both sides of the road are completely unfolded, the difference between the vertical height and the center of gravity of the access barriers 300 at the contact areas of the access barriers 300 on both sides of the access barriers 300 In order to prevent this from happening because the lower part is widened, the square frame 320 covered with the entry blocking film 300 at the uppermost end of the blocking film on both sides is rotated by more than 15 ° in the opposite direction to each other so that the contact area of the blocking film on both sides is partially mutually It was intended to solve the problem by overlapping, and this is done by forming the protrusion 230a to have a lower inclination than the inclination angle of the protrusion 230 for rotation of 90 degrees, so that when the roll wheel passes through the protrusion 230a, mechanically a certain angle ( About 15 degrees), so that the entry barriers on both sides do not diverge when the driver recognizes them, and not only can they be fully recognized, but they can also play a role in reducing the influence of wind.

In the present invention, as shown in FIG. 3, in the case of one-way two-lane or less, blocking barriers are installed on both sides of the vertical member to block vehicles entering and exiting the tunnel, thereby minimizing the flow of traffic. As shown in , the entry barrier 300 is a vertical member (not shown) and a barrier closure (not shown) in the median area along with the barrier barrier 310 installed on both sides of the road when there is a median of three or more one-way lanes. City) is additionally installed to block only one lane of both round-trip lanes and allow entry of 2 to 3 lanes, etc., so that each lane can be blocked selectively using the entry barrier 300 according to the one-way lane. It minimizes the flow of traffic and blocks vehicle entry in each lane of the road in the event of a tunnel accident, effectively preventing subsequent vehicles from attempting to enter abnormally.

In addition, the blocking film enclosure 310 has a space in the upper part of the enclosure in which the vertical support rod of the rail bracket 220 can move when unfolded and folded, and dust, foreign substances, etc. enter through the space, causing various problems It is formed in the form of a brush having elasticity to prevent inflow of foreign substances into the inside of the shielding film enclosure 310.

In addition, the controller 700 in charge of all controls of the present invention is responsible for all controls of the warning means 500 separately equipped with the tunnel entry blocking device, as shown in FIGS. 2, 3 and 8, and the warning means ( 500) has safety lighting equipment and warning devices installed inside and outside the tunnel, and the inside of the tunnel detects an unexpected situation inside the tunnel from a speed sensor installed for each section, a camera including CCTV, and generates an unexpected situation detection signal, and the above sensors By analyzing the measured data for each section received from the camera and the camera, the priority of the emergency situation is determined, and the danger signal or warning signal is generated according to the priority. Signals or warning signals can be recognized by the driver using sight and hearing, and when a danger signal is received from the integrated control server, the entry blocking device to block vehicle entry into the tunnel operates, and the speed installed inside the tunnel By interlocking with the interlocking gaze guidance light, the entry blocking device installed inside and outside the tunnel can be operated, so that not only the effective blocking function but also the warning function is added in the event of an emergency. In the tunnel entry blocking device installed inside and outside the tunnel, it is installed on the upper part of the horizontal member and on the vertical member, and as a warning means to inform the entry prohibition of vehicles entering in case of disaster risk, visually blocking entry by using the warning phrase on the barrier, as a warning means Red, yellow, and blue colors of the LED are used to enable identification even from a long distance under strong sunlight. In normal traffic conditions and when vehicles inside the tunnel are blocked and require attention, fire or traffic accident Various methods are used to prevent drivers from not recognizing, such as making it easy for drivers to recognize from a distance depending on when entry is impossible, etc., and using warning sounds to inform dangerous situations.

The warning means 500 includes at least one of a surface light, a warning light, a tunnel name display, an eye guiding light, and a speaker installed in an entry blocking device, a fire extinguisher indicator light, a gobo light, a pictogram display, a speaker, and an electric signboard installed inside the tunnel, In accordance with the danger signal or warning signal received from the integrated control server, a preset color is emitted or evacuation guidance information is displayed and a warning sound is generated.

In the present invention, as shown in FIG. 2, when the flow of vehicles is smooth according to the situation inside the tunnel, the speed-linked gaze guidance light linked to the warning means for blocking the entering vehicle from the outside of the tunnel is white at the entrance of the tunnel, The inside of the tunnel is green to secure the line of sight of the road inside the tunnel, and when the vehicle is traveling slowly at around 40km/h, the entrance and the inside of the tunnel turn yellow, and in case of congestion or an accident (fire), blinks in red so that the driver can clearly recognize it. The above colors may vary according to various regulations and commercial practices.

According to the speed-linked tunnel gaze guide light of the present invention, the combination of the blinking state of the lower lighting unit and the upper lighting unit informs the driver of accidents and dangers in the tunnel to prevent secondary and tertiary follow-up accidents and at the same time It is possible to prevent the expansion of an accident by safely inducing evacuation according to the following, and the irradiation direction of the tunnel gaze guidance light is formed at a certain angle in the opposite direction to the driver's side, which has the effect of illuminating the road surface without interfering with the driver's vision. , According to the speed-linked tunnel line guidance light of the present invention, since the control unit provided with the upper lighting unit with built-in LED light can be rotated and adjusted at various angles with respect to the fixed part, There is also an effect that can be adjusted so that the light is irradiated at a desired angle on the road surface. This angle adjustment function makes it easy to arbitrarily adjust the pattern of light irradiated to the road surface in addition to the function of enabling the angle of light irradiated to the road surface to be always irradiated at the desired angle in spite of the inclined state of the utility tunnel during the installation process of the gaze guide light. There are also effects that can be formed. In other words, the intensity and length of the light irradiated to the road surface are expressed differently depending on the angle of the control unit. Using this point, it is possible to produce various patterns of light irradiated to the road surface, which gives the driver a sense of alertness and concentration of attention. can also provide. The present invention is configured to use the upper lighting unit and the lower lighting unit at the same time to inform the driver of the situation inside the tunnel. , The inside of the tunnel is displayed or blinked in green, for example, so that the driver can accurately secure the line of sight to the road inside the tunnel.
