Description

  The present invention relates to a wall surface automatic opening and closing blade device in a station building through which a train passes, and more specifically, for example, a rapid change in the passage of a high-speed train in a station building of, for example, a shelter type constructed in a station through which a high-speed train such as a Shinkansen train passes. TECHNICAL FIELD The present invention relates to a wall surface automatic opening / closing blade device in a station building that reduces a significant pressure fluctuation.

  For example, at stations where high-speed trains such as Shinkansen trains run, especially in snowy country stations, shelter-type shapes are constructed by integrating the side walls and ceiling of the outside of the platform as measures to prevent cold weather and avoid wind and snow damage. Often, shelter-type station buildings are used.

  The pressure fluctuation generated in the station building when the high-speed train T passes through such a shelter type station building 51 will be outlined with reference to FIG.

  As shown in FIG. 10, when the high-speed train T enters the shelter-type station building 51 and the leading portion passes through, a sudden + pressure ( (Positive pressure) pressure fluctuation occurs.

  Moreover, when the tail part of the high-speed train T passes, -pressure (negative pressure) is generated due to the passage of the tail part, and pressure fluctuations similarly occur.

  For this reason, if the passage of the high-speed train T is repeated many times in the shelter-type station building 51, fatigue damage occurs in the building members of the station building 51 due to repeated pressure fluctuations, or the pressure difference between the platform and the outside due to pressure fluctuations. Strong winds are generated at the windows, doors, stairs, escalators, etc. that lead to the platform.

  In Patent Document 1, as a technique related to the present invention, for the purpose of preventing wear or wear of the tunnel and its internal structure due to shock air pressure fluctuation, near the tunnel in the high-speed train traveling direction, At the exit, a tunnel detection signal transmitter and a tunnel passage signal transmitter are installed, and on the high-speed train side, a signal receiver that receives signals from each of the transmitters, a fan control device, and a fan with a train are installed. When the vehicle passes through the tunnel at high speed, the fan with a train is driven through the blower control device based on the signal from the tunnel detection signal transmitter, and the blower is blown into the tunnel or arranged on the tunnel side. To blow into the tunnel to prevent collision between the tunnel air and the train, and to eliminate the cause of impact and noise generation. Noise prevention systems have been proposed.

  However, in the case of this patent document 1, it was a complicated system structure provided with both the said oscillator, a signal receiver, a fan control apparatus, and a fan.

  Hereinafter, a wall surface automatic opening and closing blade device in a station building according to Embodiment 1 of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, a wall surface automatic opening and closing blade device 1 in a station building 51 according to the first embodiment is a shelter type station building constructed by a vertical side wall portion 52 and a ceiling portion 53 at a station through which a high-speed train T passes. With the entry of a high-speed train T that runs on the track 55 and is arranged in a row at a predetermined interval with respect to the side wall portion 52 that divides the home 54 side and the outside. An opening is automatically formed in the side wall portion 52 in accordance with the impact air pressure fluctuation generated in this manner, and the impact air pressure fluctuation is reduced.

  The wall surface automatic opening / closing blade device 1 will be described in detail with reference to FIGS.

  As shown in FIG. 2, the wall surface automatic opening / closing blade device 1 has a rectangular parallelepiped box-shaped housing 2 in which an end surface on the platform 54 side is open and a rectangular blade attachment port 3 is provided on the outer surface of the station building 51. And the rotation center shaft 11 installed horizontally and rotatably at the center position in the vertical direction of the blade attachment port 3 in the housing 2, and the blade attachment port 3 can be closed or opened by the rotation center shaft 11. The central shaft blade 12 having a rectangular shape that supports the center position in the vertical direction and maintains the closed state with respect to the blade attachment port 3 when the wind pressure acts from the outside to the inside of the station building 51, and the upper end surface on the platform 54 side. It is attached to a range up to the position near the rotation center axis 11 in the housing 2 and the shock air pressure fluctuation from the platform 54 side when the high-speed train T passes through the station building 51 A curved shielding guide plate 13 that is guided to the lower half portion of the inner surface of the mandrel blade 12 to forcibly open the center shaft blade 12, and an end portion of the rotation center shaft that projects one end outward from one side wall of the housing 2. 11a, the other end side is extended along the outer side of the side wall of the housing 2 and the protruding end is a free end, attached to the outer side wall of the housing 2 and the rotating piece 14, A force F1 in the closing direction is applied to the central shaft blade 12 through the rotating piece 14 at all times to rotate the central shaft blade 12 in the closing direction after the impact air pressure fluctuation disappears, and the blade mounting port 3 A gas spring 15 that operates at a gas pressure, which is a first telescopic operating body that closes the gas, and is attached across the side wall of the housing 2 and the rotating piece 14, and in the closing direction of the rotating piece 14 by the gas spring 15. Drag F2 against force An oil damper 16 that is hydraulically operated as a second telescopic operation body that is applied to the central shaft blade 12 via the rotating piece 14 and delays the closing time of the central shaft blade 12. .

  The gas spring 15 includes a cylinder portion 15a and a telescopic rod portion 15b, and an end of the cylinder portion 15a is attached to a position in the vicinity of the rotation center shaft end portion 11a of the rotating piece 14 with respect to the cylinder portion 15a. The projecting end of the telescopic rod portion 15b that expands and contracts is attached to the lower position of the side wall in an “elongated” state, and is set so as to always apply the clockwise force F1 in FIG. .

Further, the resistance force when the telescopic rod portion 15b of the gas spring 15 is contracted is smaller than the force when the central shaft blade 12 is forcedly opened by impact air pressure fluctuation. The oil damper 16 includes a cylinder portion 16a and a telescopic rod portion 16b. The end of the cylinder portion 16a is attached to the outside of the attachment position of the gas spring 15 in the rotating piece 14, and is expanded and contracted with respect to the cylinder portion 16a. The protruding end of the operating telescopic rod portion 16b is attached to the lower position of the side wall in an “extended” state, and is set so as to apply a drag force F2 to the rotational force of the rotating piece 14 in the clockwise direction in FIG. ing.
That is, the magnitude relationship between the force F1 in the closing direction and the drag force F2 is F1> F2.

  The oil damper 16 has a small resistance force when the telescopic rod portion 16b is contracted, and is configured to exert a resistance force F2 against the rotational force of the rotating piece 14 in the clockwise direction when it extends.

  Examples of the curved shape of the shielding guide plate 13 include an arc shape, a substantially arc shape, and a substantially L shape with rounded corners when viewed from the side, and are not particularly limited.

  Next, regarding the operation of the wall surface automatic opening / closing blade device 1 in the station building 51 according to the first embodiment, each time during the passage from the entry of the high-speed train T to the passage / exit in normal times (time zone other than when the train is passing). The description will be given below by dividing into modes.

(Normal)
In a time zone other than when the high-speed train T does not enter the station building 51 except for when the train passes, the center shaft blade 12 passes from the gas spring 15 through the rotating piece 14 and the rotating center shaft 11 as shown in FIG. The blade attachment port 3 is fully closed by receiving the acting force F1 in the closing direction.

  At this time, even if wind pressure acts on the outer surface of the central shaft blade 12 from the outside of the station building 51, this wind pressure acts on both the upper and lower surfaces sandwiching the rotation central shaft 11 of the central shaft blade 12. It does not rotate with the central shaft 11 as a support shaft, and maintains the state where the blade attachment port 3 is fully closed.

  Therefore, during normal times when the high-speed train T does not enter the station building 51, wind and snow from the outside of the station building 51 do not enter the home 54, and passengers on the platform 54 are exposed to wind and snow and rain. There is nothing.

(When passing the train head)
When the leading portion of the high-speed train T passes, as shown in FIG. 3, the impact air pressure fluctuation that has occurred enters from the opening on the platform 54 side of the housing 2 and is guided by the shielding guide plate 13, and the central shaft blade It hits the lower half of the 12 inner surface.

  Thereby, as shown in FIG. 3, the central shaft blade 12 is forcibly rotated about 90 degrees in the direction of the arrow a1 with the rotation center shaft 11 as a support shaft, and the lower half of the blade attachment port 3 is opened. As a result, the shocking air pressure fluctuation is released to the outside of the side wall 52 of the station building 51.

  Further, as the central shaft blade 12 rotates, the rotating piece 14 also rotates in the direction of the arrow b1, and the expansion / contraction rod portion 15b of the gas spring 15 contracts. The resistance force when the expansion / contraction rod portion 15b contracts is as follows. As described above, since the center shaft blade 12 is made smaller than the force when forcedly opened due to the impact air pressure fluctuation, the center shaft blade 12 is obstructed to rotate in the direction of the arrow a1. There is no.

  Further, as the rotating piece 14 rotates in the direction of the arrow b1, the telescopic rod portion 15b of the oil damper 16 also contracts, but since the resistance force when the telescopic rod portion 16b contracts is also small, the central shaft blade There is no hindrance to the rotation of the 12 in the direction of arrow a1.

  In this way, when the leading portion of the high-speed train T passes, the lower half of the blade attachment port 3 is automatically opened by the opening operation of the central shaft blade 12, and the shocking air pressure fluctuation is generated in the station building 51. Since the pressure fluctuation as in the conventional example is reduced on the platform 54 because the escape to the outside of the side wall 52 is avoided, fatigue damage is avoided in the building members of the station building 51, and the users on the platform 54, It is possible to eliminate a situation in which a user who uses a staircase, an escalator, or the like connected to the home 54 falls and is injured, thereby ensuring the safety of the user.

  Each wall surface automatic opening / closing blade device 1 provided on the side wall portion 52 that divides the home 54 from the outside receives the pressure fluctuation generated with the passage of the high-speed train T, almost simultaneously or with a slight time interval. The opening operation of the shaft blade 12 is automatically executed, and the safety of the user is ensured throughout the home 54.

(During train passing and tail passing)
Next, when the high-speed train T further travels and passes, the shock pressure fluctuation accompanying the passage of the leading portion of the high-speed train T disappears, so that the central shaft blade 12 automatically closes the blade attachment port 3. Rotate.

  That is, as shown in FIGS. 4 and 5, after the impact air pressure fluctuation disappears, the telescopic rod portion 15a of the gas spring 15 operates in the extending direction, and the rotating piece 14 is moved in the clockwise direction (arrow b2). 4), the rotation center shaft 11 and the center shaft blade 12 are rotated in the direction of the arrow a2 shown in FIG. 4 through the rotating piece 14, and the blade attachment port 3 is automatically closed. To do.

  At this time, the telescopic rod 16b of the oil damper 16 starts to extend, and a drag force F2 (<force F1) is applied to the rotational force of the rotating piece 14 in the clockwise direction.

  As a result, the central shaft blade 12 rotates in the direction of the arrow a2 in a state where the closing time is delayed (slowly) based on the action of the force F1 and the drag F2, and automatically The blade attachment port 3 is automatically fully closed. Thereby, the open state of the central shaft blade 12 can be maintained until the −pressure after passing the tail portion of the high-speed train T is released, and pressure fluctuations when the high-speed train T passes from the station building 51 can be suppressed.

  Each wall surface automatic opening / closing blade device 1 provided on the side wall portion 52 that partitions the home 54 from the outside closes each central shaft blade 12 almost simultaneously or at a slight time interval when passing through the station building 51 of the high-speed train T. Perform the action automatically.

  According to the first embodiment described above, in the shelter-type station building 51 through which the high-speed train T passes while having a simple and inexpensive configuration having a purely mechanical structure without using any electrical or electronic equipment. In addition to reducing fluctuations in pressure when the high-speed train T passes, fatigue damage to the building members of the station building 51 can be avoided, safety of passengers on the platform 54 can be secured, and other than when the high-speed train T passes Provided is the wall surface automatic opening and closing blade device 1 in which the snow and rain from the outside of the station building 51 does not enter the home 54 during the time period, and the passengers on the home 54 are not exposed to the snow and rain. be able to.

  Next, a wall surface automatic opening and closing blade device 1A in a station building according to Embodiment 2 of the present invention will be described in detail with reference to FIGS.

  The wall surface automatic opening / closing blade device 1A in the station building 51 according to the second embodiment has basically the same configuration as the wall surface automatic opening / closing blade device 1 according to the first embodiment, but the width and depth are replaced with the housing 2 described above. However, it is characterized in that a housing 2A having the same height and double the height is adopted, and the central axis rotary blades 12 are incorporated in this housing 2A in an upper and lower two-stage arrangement. In the wall surface automatic opening / closing blade device 1A shown in FIGS. 6 to 9, the same elements as those in the wall surface automatic opening / closing blade device 1 according to the first embodiment are denoted by the same reference numerals.

  As shown in FIGS. 6 and 8, the wall surface automatic opening / closing blade device 1 </ b> A in the station building 51 according to the second embodiment is horizontally arranged from the end surface on the platform 54 side to the end surface on the outside side of the station building 51 at the longitudinal center position. A rectangular parallelepiped having a rectangular upper and lower partition plate 17 installed thereon, and provided with two upper and lower openings on the end face on the platform 54 side, and two upper and lower square blade attachment ports 3 and 3 on the outer end face of the station building 51. It has a box-shaped housing 2A.

  As shown in FIG. 6, the wall surface automatic opening and closing blade device 1A includes two rotation center shafts 11 that are horizontally installed at the vertical center positions of the upper and lower blade attachment ports 3 and 3 in the housing 2A. 11 and the rotation center shafts 11, 11 support the center position in the vertical direction in a state where each of the blade attachment ports 3, 3 can be closed or opened, and the wind pressure action from the outside to the inside of the station building 51. Occasionally, the upper and lower two-stage quadratic central shaft blades 12 and 12 that maintain the closed state with respect to the blade attachment ports 3 and 3 and the rotation in the housing 2A from the upper end surfaces of the upper and lower two-stage openings on the home 54 side. The shield guide plates 13 and 13 having two upper and lower curved shapes and the same shape as in the case of the first embodiment attached to the range near the central shafts 11 and 11, and one end on the upper side of the housing 2A From the side wall to the outside A rotating piece 14 that is connected to the upper rotation center shaft end portion 11a and that has the other end extending along the outer side of the side wall of the casing 2 and having the protruding end as a free end, the outer side of the side wall of the casing 2A, and the It is attached to the rotating piece 14, and a force F1 in the closing direction is applied to the upper central shaft blade 12 through the rotating piece 14 at all times, and the central shaft blade 12 is closed after the impact air pressure fluctuation disappears. The gas spring 15 similar to that of the first embodiment that operates by the gas pressure that is the first telescopic operation body that rotates in the direction and closes the blade attachment port 3, the side wall of the housing 2, and the rotation piece 14, a resistance force F <b> 2 against the force in the closing direction of the rotating piece 14 by the gas spring 15 is applied to the central shaft blade 12 through the rotating piece 14, and the closing time of the central shaft blade 12 is set. Second stretch to delay The oil damper 16 is the same as in the case of the first embodiment that operates by hydraulic pressure, and the upper and lower rotation center shaft end portions projecting from the side wall of the casing 2A outside the other side wall of the casing 2A as shown in FIG. 11b, 11b, and a parallel link mechanism 18 that interlocks the rotations of both rotation center shafts 11, 11 and both center shaft blades 12, 12.

  As shown in FIG. 7, the parallel link mechanism 18 includes a pair of parallel arms 19, 19 each having one end attached to each of the upper and lower rotation center shaft ends 11 b, 11 b, and each of the parallel arms 19, 19. And a connecting arm 20 for connecting the ends.

  Contrary to the case of the first embodiment, the gas spring 15 is attached by attaching the protruding end of the telescopic rod portion 15b to the position near the rotation center shaft end portion 11a of the rotating piece 14 in an "extended" state. The end of the portion 15a is attached to the side wall, and is always set to apply a force F1 in the clockwise direction in FIG.

  Contrary to the case of the first embodiment, the oil damper 16 is attached with the protruding end of the telescopic rod portion 16b in an “extended” state in the vicinity of the rotation center shaft end portion 11a of the rotating piece 14, and the cylinder portion 15a. Is attached to the side wall so that a drag force F2 is applied to the rotational force of the rotating piece 14 in the clockwise direction.

  That is, the gas spring 15 and the oil damper 16 are set to operate in the same manner as in the first embodiment.

  Next, regarding the operation of the wall surface automatic opening and closing blade device 1A in the station building 51 according to the second embodiment, it is divided into each mode from normal entry (time zone other than when the train is passing) to entry / exit of the high-speed train T. Will be described below.

(Normal)
In normal times when the high-speed train T does not enter the station 51, as shown in FIG. 6, the upper central shaft blade 12 in the housing 2 </ b> A passes from the gas spring 15 through the rotating piece 14 and the rotating central shaft 11. In response to the acting force F1 in the closing direction, the upper blade attachment port 3 is fully closed. Similarly, the lower central shaft blade 12 linked with the upper central shaft blade 12 is in a state in which the lower blade attachment port 3 is fully closed.
At this time, even if wind pressure acts on the outer surface of each of the central shaft blades 12 in the upper and lower two stages from the outside of the station building 51, this wind pressure acts on both upper and lower surfaces sandwiching the rotation center shaft 11 of each central shaft blade 12. Each center shaft blade 12 does not rotate with each rotation center shaft 11 as a support shaft, and maintains a state where the upper and lower blade attachment ports 3 are fully closed.

  Therefore, in a time zone other than when the train passes, wind and snow from the outside of the station building 51 do not enter the home 54, and passengers on the platform 54 are not exposed to wind and snow or rain.

(When passing the train head)
When the leading portion of the high-speed train T passes, as shown in FIG. 8, the generated shock air pressure fluctuation enters from the opening on the platform 54 side of the housing 2A and is guided by the shielding guide plates 13 and 13 up and down. It hits the lower half of the inner surface of each of the two central shaft blades 12.

  Thereby, as shown in FIG. 8, the center axis blades 12 are forcibly driven to rotate about 90 degrees in the direction of the arrow a1 with the rotation center shafts 11 as supporting shafts, and the upper and lower blade attachment ports 3 are arranged in two stages. 3 is opened, and the shocking air pressure fluctuation is released to the outside of the side wall 52 of the station building 51. Further, the rotating piece 14 rotates in the b3 direction shown in FIG.

  At this time, as shown in FIG. 8, a part of the impact air pressure fluctuation induced by the upper shielding guide plate 13 of the upper and lower partition plates 17 provided on the housing 2 </ b> A has an upper half in the lower blade attachment port 3. Flow and escape to the outside of the side wall 52 of the station building 51.

  The operations of the gas spring 15 and the oil damper 16 that accompany the passage of the leading portion of the high-speed train T are the same as those in the first embodiment.

  In this way, when the leading portion of the high-speed train T passes, the blade attachment ports 3 and 3 are automatically opened by the opening operation of the central shaft blades 12 and 12, and at this time, shock air pressure fluctuations occur. Since it passes through the blade attachment port 3 having a larger opening area than in the case of the first embodiment and escapes to the outside of the side wall 52 of the station building 51, the pressure fluctuation is more reliably reduced on the platform 54 than in the case of the first embodiment. In addition to avoiding fatigue damage to the building members of the station building 51, the passengers on the platform 54, as well as the passengers using the stairs and escalators connected to the platform 54, may fall and be injured. It is possible to more reliably eliminate the situation such as the user and enhance the safety of the user.

  If each wall surface automatic opening and closing blade device 1A is arranged on the side wall portion 52 that partitions the home 54 and the outside in the same manner as in the first embodiment, these are subject to pressure fluctuations that occur as the high-speed train T passes. In response, the opening operation of each central shaft blade 12 can be automatically performed almost simultaneously or with a short time interval, and the pressure fluctuation can be reduced throughout the home 54.

(During train passing and tail passing)
Next, when the high-speed train T further travels and passes, the impact air pressure fluctuation generated as the high-speed train T passes through the leading portion disappears, so that each of the central axis blades 12 of the wall surface automatic opening / closing blade device 1A. Automatically rotates in the direction of closing the blade attachment port 3.

  That is, as shown in FIG. 9, after the shocking air pressure fluctuation disappears, the telescopic rod portion 15a of the gas spring 15 operates in the extending direction, and the rotating piece 14 moves in the clockwise direction (arrow b4 direction). A rotating force F1 is applied to rotate the rotating central shaft 11 and the central shaft blade 12 in the direction of arrow a2 shown in FIG. 9 via the rotating piece 14, and the blade mounting port 3 is automatically operated by the central shaft blade 12. Block. Also, the upper and lower blade attachment ports 3 are automatically closed by the operation of the parallel link mechanism 18 in conjunction with the upper and lower central shaft blades 12 in conjunction with each other.

  At this time, the telescopic rod 16b of the oil damper 16 starts to extend, and a drag force F2 (<force F1) is applied to the rotational force of the rotating piece 14 in the clockwise direction.

  As a result, the central shaft blade 12 rotates in the direction of the arrow a2 in a state where the closing time is delayed (slowly) based on the action of the force F1 and the drag F2, and automatically The blade attachment port 3 is automatically fully closed.

  Thereby, the open state of the central shaft blade 12 can be maintained until the -pressure at the time of passing the tail portion of the high-speed train T is released, and pressure fluctuation when the tail portion of the high-speed train T passes can be reduced. .

  Each of the wall surface automatic opening / closing blade devices 1 provided on the side wall portion 52 that divides the home 54 from the outside is almost the same as the above mentioned central shaft blade 12 while passing through the station building 51 of the high-speed train T or at a slight time interval. The closing operation for the blade attachment port 3 is executed.

According to the second embodiment described above, in the shelter-type station building 51 through which the high-speed train T passes, the electrical equipment or the electronic equipment is not used at all and the structure is simple and inexpensive with a pure mechanical structure. The blade attachment port 3 secures a wide opening area to more reliably reduce pressure fluctuations when passing through the high-speed train T, avoiding fatigue damage to the building members of the station building 51, passengers on the platform 54, etc. In the time zone other than when the train is passing, the snow and rain from outside the station building 51 does not enter the home 54, and the passengers on the home 54 are exposed to the snow and rain. The wall surface automatic opening / closing blade device 1A can be provided.
In the second embodiment described above, the wall surface automatic opening / closing blade device 1A having the upper and lower two-stage configuration has been described. However, the present invention is not limited to this, and the upper and lower N (N is a positive integer such as 3, 4,. Of course, it is good also as a blade | wing apparatus.

  The present invention provides a shelter-type station building with a closed side wall and ceiling, as well as an apparatus for suppressing pressure in a subway station building where trains run, train tunnels, etc. In order to improve it, it is applicable to a wide range of light extraction by constituting the material such as the blade part with a transparent resin.
