Description

A soundproof panel automatic open structure of a soundproof tunnel and a soundproof wall}

The present invention relates to an automatic opening and closing structure of a soundproof tunnel and a soundproof wall, and more particularly, to a soundproof tunnel and a soundproof plate automatic opening and closing structure of a soundproof tunnel to automatically open and close the soundproof plate according to temperature changes in a tunnel.

In general, sound barriers and soundproof tunnels (tunnel-type sound barriers) may be used as representative noise countermeasures for reducing noise damage on adjacent roads, offices, bridges, and the like.

The soundproof wall and the soundproof tunnel are usually in the form of a built-in structure in which pillars are erected at regular intervals and a soundproof plate is inserted between the pillars and the pillars.

Such soundproof tunnels are known through "Korean Registration No. 10-1188485," and in addition to these patent documents, soundproof tunnels and soundproof walls may be known as well-known technologies.

The soundproof wall and the soundproof tunnel made of the soundproof plate of the fixed type can obtain a soundproofing effect, but are vulnerable to structural safety that may be caused by wind pressure due to strong winds.

In addition, the soundproof tunnel-type structure of the enclosed structure has a problem that the internal temperature is rapidly increased during the heat wave in the summer, in particular, the soundproof tunnel-type structure installed on the railroad tracks due to the rapid temperature rise inside the tunnel, The tank supplying the tank may be exposed to high temperature, and the construction of the train line exposed to the high temperature may cause a two-line phenomenon in which the pantograph of the train falls instantaneously with the tank line, and the abrasion of the pantograph and the tank line, disconnection or insulation It can be done by accidents such as destruction.

In addition, railway rails are newly stretched due to temperature changes, and if the increase is excessively increased due to rapid temperature rises, it is important to secure the rails against temperature rises because of warpage deformation, rail rise and rail elongation.

As shown in FIG. 1, when the rail axial force is excessively acted on as the rail temperature rises, and when the rail temperature is between the Ta point and the Tc point, only a slight external force is applied and the curved state is bent in a stable state. Go to

In addition to this behavior, the influencing factors are vibrations, transverse pressures,

Up-lift of the rails and the buckling of the rails can occur in the outward direction of the gauge with weak flexural rigidity.

In order to prevent railway car accidents caused by these problems, rail car operation is regulated step by step according to the rail temperature, and water hoses are installed in the center of the tracks to spray water in the middle of the rails in order to prevent summer rail loading, The situation is managing temperature.

However, the above-described rail temperature management method not only causes very troublesome problems, but also hardly becomes a fundamental countermeasure.

Therefore, there is a need for a method that can continuously manage the temperature of the railway rail to secure the safety of the train.

It should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Hereinafter, with reference to the accompanying Figures 2 to 5b it will be described for the automatic opening and closing structure of the soundproof tunnel and soundproof wall according to a preferred embodiment of the present invention.

The automatic opening and closing structure of the soundproof tunnel and soundproof wall of the soundproof tunnel allows the interior of the soundproof tunnel to be automatically opened and closed so that the temperature inside the soundproof tunnel can always be maintained at an appropriate temperature.

Accordingly, the rail stability can be continuously maintained regardless of the outside temperature, and the convenience of temperature management inside the soundproof tunnel can be improved.

In the present specification, for convenience of description, the soundproof tunnel is illustrated and described as an example.

The automatic opening and closing structure of the soundproof tunnel and the soundproof wall of the soundproof wall is shown in FIGS. 2 to 5b, as shown in FIGS. 2 to 5b, the control unit 100, the temperature sensor 200, the frame 300, the soundproof plate 400, and the driving unit 500. And a lifting bar 600, a connecting member 700, and a guide part 800.

The controller 100 controls the driving unit 500 according to the temperature inside the soundproof tunnel.

The control unit 100 controls the driving unit 500 power ON / OFF, it is provided to set the reference temperature value for opening and closing the soundproof tunnel.

Next, the temperature sensor 200 measures the internal temperature of the soundproof tunnel, and transmits the measured temperature value to the controller 100.

By such a configuration, the controller 100 receives the temperature from the temperature sensor 200 and controls the operation of the driving unit 500 by comparing with a preset reference temperature value.

Next, the frame 300 constitutes a frame in the form of a soundproof tunnel.

The soundproof tunnel may be provided in various forms, and the frame of the soundproof tunnel using the frame 300 may also be variously designed.

At this time, the frame 300 is installed in the form of a lattice, each of the soundproof plate 400 is installed in the opening 310 of the frame 300 formed by the grid.

Next, the soundproof panel 400 is configured to shield the inside of the soundproof tunnel at the side of the soundproof tunnel, and serves to block the noise of the vehicle passing through the soundproof tunnel from outside the soundproof tunnel.

The sound insulation panel 400 is provided for each opening 310 of the frame 300 having a lattice shape.

The material of the sound insulation board 400 is not particularly limited, and may be any material having excellent sound insulation and sound absorption effects.

The sound insulation panel 400 is preferably composed of a fixed plate 410 and a movable plate 420.

The fixing plate 410 is a panel fixed on the frame 300 and fixedly installed in the opening 310 of the frame 300.

That is, the fixing plate 410 is a configuration that is always fixed without flow on the frame 300.

The movable plate 420 is configured to open and close the interior of the soundproof tunnel, and is configured to flow by the power of the driving unit 50 to be described later.

In order to vary the internal temperature of the soundproof tunnel, it is necessary to allow the inflow of outside air into the soundproof tunnel through opening and closing of the soundproof panel 400, but the soundproof panel 400 may be configured to be opened and closed, but the construction cost and energy consumption In terms of minimizing the soundproof plate 400 is configured to be opened and closed only.

Of course, the soundproof plate 400 may be installed so that the whole can be opened and closed.

It is understood that the ratio of the fixed plate 410 and the movable plate 420 can be considered in the design process, it is preferable that the fixed plate 410 and the movable plate 420 are installed alternately on the frame 300.

Meanwhile, as shown in FIG. 5A, the movable plate 420 is preferably positioned stepwise from the fixed plate 410 into the soundproof tunnel.

This is to prevent interference with the fixed plate 410 in the process of moving the movable plate 420 for opening and closing the soundproof tunnel.

In this case, as the movable plate 420 is stepped from the fixed plate 410, a gap may occur between the movable plate 420 and the opening 310.

In order to maintain airtightness between the movable plate 420 and the opening 310, an airtight member S is installed around the opening 310 of the frame 300 corresponding to the movable plate 420, as shown in FIG. 5A. This is preferred.

The airtight member S is configured to maintain the airtight in a state in which the movable plate 420 is in close contact with the opening 310, and to increase the sound insulation efficiency.

At this time, in order for the movable plate 420 to be in close contact with the airtight member S, the movable plate 420 should be larger than the size of the opening 310 corresponding to the movable plate 420.

Next, the driving unit 500 generates power for flowing the movable plate 420.

The drive unit 500 is preferably a motor for generating forward and reverse rotational power.

Next, the lifting rod 600 is axially coupled to the driving unit 500, and is rotated forward and reverse by the power of the driving unit 500.

The lifting rod 600 is preferably composed of a screw, or provided with a threaded bar (bar).

Next, the connection member 700 is connected between the movable plate 420 and the elevating rod 600, and serves to vary the rotational movement of the elevating rod 600 into a linear movement.

The connection member 700 is provided in a screw-connected configuration to the lifting bar 600.

Accordingly, when the elevating rod 600 is rotated by the power of the driving unit 500, the connecting member 700 moves in the height direction of the elevating rod 600, and the movable plate connected to the connecting member 700. 420 is lifted in the side height direction of the frame 300 while being linked to the linear motion of the connecting member 700.

As such, the opening 310 of the frame 300 may be opened or closed through the lifting operation of the movable plate 420.

Next, the guide portion 800 serves to guide the lifting operation of the movable plate 420 for smooth lifting of the movable plate 420.

The guide part 800 is bent from the frame 300 and is configured to guide only both end portions of the movable plate 420.

Due to the configuration of the guide portion 800, the lifting path during the lifting of the movable plate 420 does not occur.

At this time, although not shown, for the flexible lifting of the movable plate 420, a slide groove is formed in the guide portion 600, and rollers are provided on both sides of the movable plate 420 to raise and lower the movable plate 420. By allowing the roller to roll along the slide groove, the movable plate 420 can be made more flexible.

Hereinafter, the automatic opening and closing structure of the soundproof plate of the soundproof tunnel and the soundproof wall having the above-described configuration will be described.

A soundproof tunnel consisting of the frame 300 and the soundproof panel 400 is provided.

The soundproof tunnel section is prepared in consideration of the distance that can cause noise complaints in accordance with the vehicle driving.

On the other hand, when a heat wave occurs due to abnormal climate change, the internal temperature of the soundproof tunnel is measured higher than the outside air temperature.

If the soundproof tunnel is installed on a track on which a railroad vehicle runs, it is necessary to lower the temperature inside the soundproof tunnel to maintain the proper temperature.

To this end, the temperature sensor 200 always measures the temperature inside the soundproof tunnel, and when the measured temperature value exceeds the set value, the controller 100 immediately operates the driving unit 500.

At this time, the elevating rod 600 is rotated by the rotational power of the driving unit 500.

At this time, as the connecting member 700 screwed to the elevating rod 600 moves straight upward, the movable plate 420 connected to the connecting member 700 is guided through the guide portion 800, as shown in Figure 5b. Ascended upwards.

Accordingly, the opening 310 corresponding to the movable plate 420 is completely opened, and as the outside air is introduced into the soundproof tunnel through the open opening 310, the temperature inside the soundproof tunnel is lowered.

Then, when the temperature inside the soundproof tunnel is lower than the set value, the control unit 100 operates the driving unit 500.

As the driving unit 500 reversely rotates the elevating rod 600 by generating reverse rotational power, the movable plate 420 is in the original position as shown in FIG. 5A.

At this time, the edge of the movable plate 420 is in close contact with the airtight member S to maintain the airtightness of the opening 310.

Such a series of processes are repeated through the temperature detection of the temperature sensor 200, and as these processes are repeated, the temperature inside the soundproof tunnel is always maintained properly.

Accordingly, the rail temperature inside the soundproof tunnel can be properly and efficiently managed.

Furthermore, it is possible to prevent the train accident due to the rail deformation caused by the temperature rise.

On the other hand, the movable plate 420 and the fixed plate 410 may be provided in a straight line without stepping.

This is presented as another embodiment of the present invention, and will be described with reference to the accompanying FIGS. 6 to 7B.

Prior to the description, the same components as in the preferred embodiment are denoted by the reference numerals, and detailed description thereof will be omitted.

The fixed plate 410 and the movable plate 420 are alternately installed on the frame 300, and the movable plate 420 and the fixed plate 410 are not stepped as they are installed in a straight line in the height direction of the soundproof plate. . That is, the size of the movable plate 420 is formed to correspond to the size of the opening 310 as shown in FIG.

The lifting rod 600 is configured to allow the movable plate 420 to flow, and includes a driving shaft 610 and a lifting shaft 620.

The drive shaft 610 is axially coupled to the drive unit 500 and rotated forward and reverse.

The drive shaft 610 is composed of a male screw forming a screw thread.

The lifting shaft 620 is lifted by being interlocked by the rotation of the driving shaft 610 and screwed to the driving shaft 610.

The lifting shaft 620 is formed with a female screw 621 for screwing the drive shaft 610.

The connection member 700 is connected between the elevating shaft 620 and the movable plate 420 of the elevating rod 600, and is provided as a cylinder that generates power for pushing or pulling the movable plate 420.

Hereinafter, the operation of the soundproof tunnel and the soundproof plate automatic opening and closing structure of the soundproof wall according to another embodiment having the above-described configuration will be described.

The temperature sensor 200 constantly measures the temperature inside the soundproof tunnel, and when the measured temperature value exceeds the set value, the controller 100 immediately operates the cylinder 700 to pull the movable plate 420 into the soundproof tunnel.

In this manner, the movable plate 420 opens the opening 310 primarily as shown in FIG. 7A.

That is, since a play occurs between the movable plate 420 and the opening 310 by the operating distance of the cylinder 700, the play is opened by the play.

Next, the driving unit 500 is operated to rotate the driving shaft 610.

At this time, since the lifting shaft 620 is screwed to the driving shaft 610, the lifting shaft 620 is raised by the rotation of the driving shaft 610.

Accordingly, the movable plate 420 connected to the lifting shaft 620 is raised together with the lifting shaft 620 as shown in FIG. 7B to completely open the opening 310.

Then, as the outside air is introduced into the soundproof tunnel through the open opening, the temperature inside the soundproof tunnel is lowered.

Then, when the temperature inside the soundproof tunnel is lower than the set value, the control unit 100 operates the driving unit 500.

As the driving unit 500 reversely rotates the driving shaft 610 by generating reverse rotational power, the lifting shaft 620 is lowered to correspond to the opening 310 as illustrated in FIG. 7A.

Next, by operating the cylinder 700 to push the movable plate 420, the movable plate 420 closes the opening 310.

Such a series of processes are repeated through the temperature detection of the temperature sensor 200, and as these processes are repeated, the temperature inside the soundproof tunnel is always maintained properly.

Accordingly, the rail temperature inside the soundproof tunnel can be properly and efficiently managed.

Furthermore, it is possible to prevent the train accident due to the rail deformation caused by the temperature rise.

As described above, the automatic opening and closing structure of the soundproof tunnel and the soundproof wall according to the present invention allows the internal temperature of the soundproof tunnel to be optimized at all times, specifically, the rail temperature, through the full opening of the soundproof plate.

Accordingly, it is possible to prevent the phenomenon such as rail bending and rail buckling caused by the rise of the rail temperature to prevent large accidents such as train derailment.

Although the present invention has been described in detail with respect to the embodiments described, it will be apparent to those skilled in the art that various modifications and variations are possible within the spirit of the present invention, and such modifications and variations are obviously belonging to the appended claims.
