Referring to FIG. 1, the tunnel entry vehicle protection system of the present invention has a tunnel 100. The tunnel 100 may be formed such that both sides thereof are opened and the inside thereof is hollow. A vehicle can enter both sides of the tunnel 100. The bottom surface of the tunnel 100 is constructed of a roadway through which the vehicle passes and can have bidirectional lanes or unidirectional lanes in which the vehicle can pass bidirectionally or in one direction have.

Referring to FIG. 1, a flow path panel 200 is formed at an end of a tunnel 100. The duct panel 200 may be provided at both ends of the tunnel 100, and one end thereof is fixed to the inner surface of the tunnel 100.

In general, the tunnel 100 is formed in a semicircular shape, and the flow panel 200 can also be extended to form a circular arc of a predetermined angle along the inner surface of the tunnel 100 in conformity with the shape of the tunnel 100 have.

In addition, one side of the channel panel 200 is opened to allow air blown from the outside of the tunnel 100, and the inside of the channel panel 200 has a hollow shape. At this time, it is preferable that the flow panel 200 has an inclined shape such that the cross-sectional area of the flow panel 200 decreases toward the inside of the tunnel 100.

1 and 2, a reinforcing bar 300 supporting the flow panel 200 is formed. The reinforcing bar 300 is formed in order to prevent the flow panel 200 from falling down to the bottom when the strong wind blows from the outside into the tunnel 100 and to stably fix the flow panel 200 . The reinforcing bar 300 is provided at an end of the flow panel 200, that is, in a direction adjacent to the outside of the tunnel 100, so as to support the other open side of the flow panel 200. The reinforcing bar 300 may extend along the inner surface of the tunnel 100 in the same manner as the flow panel 200.

Referring to FIGS. 1 and 2, a ventilation fan 400 is provided above the tunnel 100. The plurality of ventilation fans 400 may be spaced apart from each other by a predetermined distance according to the length of the tunnel 100. Contaminated air (exhaust gas of a vehicle, tire dust, fine dust, etc.) inside the tunnel 100 can be discharged to the outside through the ventilation fan 400.

Referring to FIGS. 1 and 2, a dry discharge port 500 communicating with the flow panel 200 is formed. The drying and discharging port 500 is formed for discharging the outside air introduced into the passage panel 200 into the tunnel 100. That is, since the open area of the dry discharge port 500 is smaller than the area of the inside of the flow passage panel 200, the air introduced from the outside can be discharged to the dry discharge port 500 with a constant pressure. At this time, the direction in which the dry discharge port 500 is directed is formed in a direction perpendicular to the bottom surface, so that outside air can be sprayed toward the bottom surface of the area where the vehicle enters in the tunnel 100.

Therefore, it is possible to prevent a phenomenon in which a vehicle slides due to a water film phenomenon due to rain by drying a bottom surface on which a vehicle enters in a rainy weather during a rainy day, and to prevent the road surface from freezing in winter, So that the effect can be achieved.

Referring to FIGS. 2 and 3, a circulation discharge port 600 communicating with the flow panel 200 and installed at a position spaced apart from the dry discharge port 600 is provided. The circular discharge port 600 is formed so as to incline in a direction inclined by a predetermined angle. That is, the circulation discharge port 600 has the purpose of making the contaminated air inside the tunnel 100 mild by spraying the outside air of the tunnel 100 flowing into the flow path panel 200 so as to be inclined at a certain angle.

More specifically, the air injected from the circulation and discharge port 600, which is inclined at a certain angle, travels on the inner wall surface of the tunnel in a downward direction of the tunnel 100. And some are injected in the downward direction of the tunnel. At this time, since the ventilation fan 400 continuously operates to discharge the air inside the tunnel 100 to the outside, fresh air flows from the outside of the tunnel 100 through the circulation discharge port 600 into the inside of the tunnel, The inside air circulates and sinks to the lower side of the tunnel 100 to raise the pollutants distributed. The polluted air and the polluted air can be discharged to the outside of the tunnel 100 through the ventilation fan 400.

3, an induction plate 201 having a curved inclination in a direction opposite to the direction of the air flowing into the flow channel panel 200 is formed at the edges of the dry discharge port 500 and the circulation discharge port 600 adjacent to the flow channel panel 200, . The induction plate 201 is formed to guide the movement of the air to the respective discharge ports so that the inflow air can flow smoothly into the dry discharge port 500 and the circulation discharge port 600.

Referring to FIG. 3, a flow rate sensor 210 may be provided in the flow panel 200. This is for the purpose of measuring the amount of air flowing outside the tunnel 100.

Referring to FIG. 3, a power generation fan 700 may further be provided in the flow panel 200. The power generation fan 700 is preferably formed at a position adjacent to the end of the flow path panel 200, that is, the outside of the tunnel 100. The power generation fan 700 can be operated by receiving electric power from the outside and the amount of air introduced from the outside of the tunnel 100 can be increased because the power generation fan 700 is driven.

Meanwhile, when the amount of air measured by the air flow rate sensor 210 is lower than a user-specified set value, the generator fan 700 is driven so that air outside the tunnel 100 is forced to flow.

On the other hand, when the amount of air measured by the air flow rate sensor 210 is equal to or greater than the set value, power to be transmitted to the power generation fan 700 is cut off and driving of the power generation fan 700 is stopped. And the circulation and discharge port 600. At this time, the power generation fan 700 can be formed of a wind power generator that can rotate according to the flow of air flowing from outside the tunnel 100 and generate a certain amount of electric power.

Accordingly, when the electric power generated by the electric power generating fan 700 is supplied and stored as a separate rechargeable battery and then the electric power generating fan 700 is operated, the electric power charged in the rechargeable battery can be supplied to the electric power generating fan 700.

Referring to FIG. 3, a heat generating unit 800 may be provided at an end of the dry discharge port 500. The heat generating unit 800 includes a heat ray 810 that receives heat from the outside. At this time, the heating wire 810 may receive heat generated by the power generated by the power generation fan 700. That is, air heated to a predetermined temperature can be sprayed on the bottom surface of the tunnel 100 due to the heat generating unit 800 formed on the dry discharge port 500. Therefore, it is possible to prevent the freezing portion of the entrance road portion of the winter tunnel 100 from being frozen through the heat generating portion 800, and it is possible to dry the bottom surface quickly in case of rainy weather.

In addition, when the vehicle enters the tunnel 100, moisture often occurs in the front glass of the vehicle due to a temperature difference between the outside of the tunnel 100 and the inside of the tunnel 100. In the case where the dry discharge port 500 And the front glass of the vehicle are in contact with each other.

Referring to FIG. 3, a temperature sensor 2200 for measuring the temperature of air flowing into the tunnel 100 is provided in the flow panel 200. When the temperature measured by the temperature sensor 220 is lower than the user-set temperature, the heating unit 800 operates and hot air is injected through the drying and discharging opening 500. On the contrary, when the temperature measured by the temperature sensor 220 is equal to or higher than the user-set temperature, the operation of the heat generating unit 800 is stopped and air having a temperature outside the tunnel 100 is injected into the drying and discharging port 500.

The temperature set by the user is preferably set within a range of about 10 to 25 DEG C, and can be divided into winter and summer. In addition to the temperature sensor 220, a humidity sensor or the like may be added.

Referring to FIGS. 2 and 3, a plurality of drying outlets 500 may be formed to be spaced apart from each other by a predetermined distance in the inner direction of the tunnel 100. The respective dry discharge openings 500 are formed so as to have a wider diameter so as to gradually increase the area where the air is sprayed. That is, the amount of air injected from the neighboring another dry discharge port 500, which is spaced apart from the dry discharge port 500 disposed at a position adjacent to the flow panel 200, in the inner direction of the tunnel 100, is injected more.

This is to reduce the noise generated when the vehicle comes into contact with the air discharged from the dry discharge port 500 and the windshield of the vehicle when the vehicle enters the tunnel 100. That is, the amount of air injected from each of the drying and ejecting openings 500 sequentially increases along the traveling direction of the vehicle and contacts the front glass of the vehicle, so that the noise generated when the air collides with the vehicle can be reduced.

Referring to FIG. 4, a plurality of circulation discharge openings 600 are formed so as to be spaced apart from each other at a predetermined interval in the inner direction of the tunnel 100, like the dry discharge openings 500. Each of the circulation discharge ports 600 is disposed such that the angle of inclination toward the inner side of the tunnel 100 increases.

That is, the circulation discharge port 600 is positioned at an angle a1 of the circular discharge port 600 adjacent to one side of the airflow panel 200 in which the air is introduced from the passage panel 200, based on a virtual vertical line O perpendicular to the bottom surface, (A2, a3, and a4) formed by the neighboring other circulation discharge openings 600 spaced apart in the inner direction of the discharge port 600 are gradually tilted.

2, when the air injected from the circulation discharge port 600 is injected while being inclined at a certain angle with respect to each other, the direction in which the air is injected in the inward direction of the tunnel 100 is changed while striking the air injected from the dry discharge port 500 . The pollutant distributed in the bottom of the tunnel 100 is moved toward the inside of the tunnel 100 and at the same time the ventilating fan 400 is operated, And can be discharged to the outside.

The control unit 900 is connected to the temperature sensor 220 and the air flow rate sensor 210. The control unit 900 analyzes the data values measured by the respective sensors and drives the heat generator 800 and the power generation fan 700. The control unit 900 is connected to a power storage unit 910 that stores power generated by the power generation fan 700 and supplies power stored before being supplied with the commercial power to the heating unit 800 and the power generation fan 700 Can supply.

Referring to FIG. 6, a guide rib 110 is formed in the tunnel 100 along the longitudinal direction of the tunnel 100. The guide rib 110 is positioned adjacent to the bottom surface of the tunnel 100 and has a shape bent at a predetermined angle around the inside of the tunnel 100. The guide rib 110 has the purpose of moving circulating and moving air along the inner surface of the tunnel 100 from the lower side of the tunnel 100 to the upper side of the tunnel 100 where the ventilation fan 400 is located . That is, the air moving along the inner side surface of the tunnel 100 along the curved shape of the guide rib 110 moves to the bottom surface of the tunnel 100 and at the same time, And can be discharged to the outside by the ventilation fan (400).
