A circular ventilation hole 9 is provided in the blower 3 at a portion corresponding to the intake hole.

A semi-transparent, slightly breathable bag-shaped circuit breaker 4 that can be expanded and contracted so as to surround the exhaust port of the blower 3 is mounted inside the box 1, and the blower 3 is operated to shut off the circuit breaker 3. When air is supplied into the circuit breaker 4 (see the arrow in FIG. 4), the air pressure inside the circuit breaker 4 rises and extends substantially horizontally from the opening 2 of the box body 1 to maintain the tension mode. Then, the passage 5 such as a road is closed (see FIG. 5).
After the circuit breaker 4 reaches the tension mode, even if the air is continuously supplied from the blower 3, the supplied air is discharged to the outside from the breathable portion of the circuit breaker 4, and the blower 3 is used. The amount of air supplied from the circuit breaker 4 and the amount of air leaked from the circuit breaker 4 are balanced, and the circuit breaker 4 has a structure that maintains a tension mode and does not burst due to air pressure.

The length of the circuit breaker 4 in the extended state in the horizontal direction is 5 m, the outer diameter of the cylinder is 50 cm, and the tip portion is slightly sharp. Further, a plurality of water sections 7 are attached to the lower edge portion.

Next, when the operation of the blower 3 is stopped, the air pressure inside the circuit breaker 4 is reduced and the tension mode is relaxed.
Therefore, when the underpass becomes submerged to a dangerous depth or a disaster occurs and it becomes necessary to block the passage of the passage 5 at a predetermined position, the blower 3 is operated to enter the circuit breaker 4. When air is supplied, the air pressure inside the circuit breaker 4 rises and extends substantially horizontally from the opening of the box body to maintain the tension mode and close the passage 5.

Further, when the closure of the passage becomes unnecessary, when the operation of the blower 3 is stopped as described above, the air pressure inside the barrier 4 is reduced, the tension mode is relaxed, and the blocked state is released. , The blocked state of the passage 5 will be released.

The structure is such that the left door 13B does not open unless the door 13A opens.

The locking device 14 is equipped with a solenoid 17 that is connected to an electric wire 16 and operates by energization, and an operating rod 18 that is vertically movablely attached to the lower end of the solenoid 17 and is pulled upward by energization of the solenoid 17. ing. Further, a guide pin 19 extending in the horizontal direction is planted at a predetermined position of the operating rod 18. A coil spring 20 for urging the working rod 18 downward is wound around the outer periphery of the working rod 18 between the lower end of the solenoid 17 and the guide pin 19. The lower end of the operating rod 18 is cut diagonally.

An engaging hole 21 into which the working rod 18 can be inserted is provided in a portion of the bottom surface of the box 1 corresponding to directly below the working rod 18 with the door 13A on the right side closed. The solenoid 17 is fixed to a support plate 22 having a flat surface in the vertical direction, and the support plate 22 is fixed to the back surface of the door 13A on the right side.
The support plate 22 is provided with an elongated hole 23 through which a guide pin 19 planted in the operating rod 18 is inserted and slides inside.
Therefore, as the operating rod 18 moves up and down according to the on / off of the energization to the solenoid 17, the guide pin 19 also slides in the elongated hole 23 in the vertical direction.
Then, when the solenoid 17 is energized, the operating rod 18 is pulled toward the solenoid 17 against the urging force of the coil spring 20, and the lower end portion of the operating rod 18 is the bottom surface portion of the box body 1. It comes out upward from the engagement hole 21 and is in an unlocked state.
Further, when the energization is stopped, the operating rod 18 is separated from the solenoid 17 by the urging force of the coil spring 2 and is locked.

The 12 and the solenoid 17 are connected to the switch 30 via a timer 31. These circuits are housed in the control panel box 11.
Thus, when the circuit breaker 4 is housed in the box body 1 and the left and right doors 13A and 13B are closed (see FIG. 1) and the switch 30 is turned on, the blower 3 starts blowing air. At the same time, the light emitting ball 8 also lights up.

At the same time, the rotary lamp 12 also starts operation and the solenoid 17 is also energized, the locking device 14 is unlocked, the circuit breaker 4 starts expanding, and the left and right doors 13A and 13B are opened. The circuit breaker 4 starts to bulge in the horizontal direction.
At this time, the solenoid 17 and the beacon 12 are configured to be energized for 60 seconds by the timer 31, and the left and right doors 13A and 13B are opened during that time. Therefore, even if the solenoid is locked thereafter, the solenoid is used. There is no problem only that the operating rod 18 of 17 is lowered downward. It takes about 30 seconds from the start of expansion of the circuit breaker 4 to the tension mode.

Therefore, as is clear from FIG. 6, the light emitting ball 8 and the rotating lamp 12 emit light at the same time as the blower 3 operates, the locking device 14 is unlocked, and after 30 seconds, the circuit breaker 4 becomes a tension mode. Further, after 30 seconds, the rotary lamp 12 is stopped, the energization of the solenoid 17 of the locking device 14 is stopped, and the operating rod 18 is lowered by gravity and the urging force of the coil spring 20.
The time setting of the timer 31 may be less than or longer than 60 seconds, and the blower 3 and the light emitting ball 8 block the time required to keep the circuit breaker 4 in the tension mode, that is, the passage or the like. It may be operated for a certain period of time (X hours).
When the circuit breaker 4 is housed in the box body 1, the operating rod 18 may be pushed upward against the force of the coil spring 20 with the key 27 or the fingertip.

Next, a second embodiment of the present invention will be described with reference to FIGS. 8 to 12.
In these figures, the same parts as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted.
In FIGS. 8 to 10, the holding plate 32 having an L-shaped cross section having four screw holes 33 formed on the side of the inner ceiling surface of the box 1 corresponding to the right door 13A is screwed (not shown). ) Is fixed. A solenoid 34 is fixed to the vertical surface of the holding plate 32, and the magnetized portion (adsorption portion by magnetic force) 35 is configured to be selectively magnetized on the back side of the right door 13A.

When the right door 13A itself is made of a magnetic material such as iron, the right door 13A is directly magnetized to the magnetized portion 35 of the solenoid 34, but the right door 13A is non-magnetic such as aluminum. When it is formed of a body, it is preferable to fix a magnetic member such as an iron piece to a portion corresponding to the magnetized portion 35 inside the right door 13A.
When the solenoid 34 is energized, a magnetic field is generated, and when the right door 13A is closed in the energized state, the solenoid 34 is fixed to the opening 2 as it is as shown in FIG.

Next, the operation of the rotary lamp 12, the solenoid 34, the blower 3, and the light emitting ball 8 will be described with reference to FIGS. 11 and 12.
FIG. 12 is a block diagram showing an outline of the functions of the electric circuit, in which the power supply 29 is formed of an AC power supply or a battery and is connected to the main switch 35. Further, the blower 3 and the light emitting ball 8 are directly connected to the main switch 35, and are also connected to the rotary lamp 12 via a timer 31.
Further, the solenoid 34 is connected to the power supply 29 via the solenoid switch 36, the main switch 35 is also connected to the solenoid switch 36, and the main switch 35 and the solenoid switch 36 are in an or relationship, that is, either switch 35. , 36 are controlled to be electrically conductive. These circuits are housed in the control panel box 11.

Thus, when the circuit breaker 4 is housed in the box body 1, the solenoid switch 36 is turned on, during which the solenoid 34 generates a magnetic field, and the left and right doors 13A and 13B are closed. It will continue to be fixed in the opening 2.
Then, at the time when it becomes necessary to operate the circuit breaker 4 (T1), if the operator or the like turns on the main switch 35, the solenoid switch 36 is turned off at the same time, the energization to the solenoid 34 is cut off, and the locking device is locked. 14 is unlocked. When the main switch 35 is turned on, the locking device 14 is unlocked, and at the same time, the blower 3 operates to supply air into the circuit breaker 4, and the issuing ball 8 emits light for a certain period of time t ( The rotary lamp 12 rotates by the time until the circuit breaker 4 completes the extension).

Further, at the time when the circuit breaker 4 is housed (T2), if the operator or the like turns off the main switch 35, the blower 3 stops operating, the issuing ball 8 turns off, and the solenoid switch 36 turns on. The solenoid 34 is energized to generate a magnetic field.
Then, when an operator or the like contracts the circuit breaker 4 and stores it in the box body 1 and closes the left and right doors 13A and 13B, the doors 13A and 13B are locked by the locking device 14 in the same manner as described above.

Some solenoid switches generate a magnetic field when the solenoid is not energized and stop the magnetic field when the solenoid switch is energized. When such a solenoid switch is used, the operation of the solenoid 34 is opposite to that of the solenoid switch 34. That is, while the solenoid is not energized, a magnetic field is generated, and the doors 13A and 13B are magnetized and fixed to the opening 2.
On the other hand, when the solenoid is energized, the magnetic field is released, and the doors 13A and 13B can be separated from the opening 2.
