Abstract

[PROBLEMS] To enable a small boat to pass during normal times, and to use a sluice that automatically closes rivers without delay due to the power of this water increase without using electric power or other power sources for abnormal water increase such as tsunami. provide. The left and right waterproof doors are provided by providing double-sided sluices along the left and right walls of the seawall, and the upper bearings 11 and 12 of the main shaft 9 of the waterproof door having the structure of the vine ball screws 13 and 14. When the tsunami or the like is pushed against the rotational force of the left and right waterproof door fixing devices 21 and tries to rotate in the closing direction due to its own weight, the floating body 22 of the door fixing device rises and the door When the floating support rod protrusions 24 are removed from the fixing latches 20, the right and left waterproof doors are released from the restraint, and the rotational force is restored, and the waterproof doors are closed by the tsunami force approaching the waterproof doors.

Description

  The structure of a sluice that automatically protects against water increase during abnormal conditions.

  When a flood caused by a tsunami rushes into a river protected by a low embankment, a new high tide embankment for tsunami countermeasures is necessary to prevent this. It is necessary to install a sluice that can be closed immediately when the water is opened. There is a demand for an economical sluice gate that can cope with flooding caused by tsunami.

  During normal times, small boats are allowed to pass through, and without the use of electricity or other power sources for abnormal water increases such as tsunamis, the power of this water increase automatically tries to develop a sluice that closes rivers without delay .

  In the structure of the sluice gate installed between the left and right high tide embankments, the present invention provides the left and right pillars 7 of the outer frame of the double sluice gate installed along the left and right walls 5 of the tide embankment. Each upper bearing 11 is mounted, the main shaft 9 of the waterproof door 8 is suspended by this bearing, and held vertically by the lower bearing 19, and the left upper bearing 11 is constructed of the left swoop ball screw 13, the right upper part By making the bearing 12 the structure of the right swirl ball screw 14, the heavy left and right waterproof doors 8 are lowered along the screw surface by their own weights, and try to rotate leftward or rightward in the direction of closing the waterproof door. The rotational force is held by meshing the protrusions (24) attached to the floating body support rods 23 of the left and right waterproof door fixing devices 21 and the fixing door 20 for fixing the waterproof door.

  When a tsunami or the like is pushed, the floating body 22 of the waterproof door fixing device 21 is lifted, and the floating body support rod 23 is also lifted, and the projection 24 attached thereto is detached from the fixing door 20 for the waterproof door. Since the floating body support rod 23 is connected by a long connecting rod 26, both the support rods are lifted at the same time, so that the left and right protrusions 24 are released at the same time, and the restraint of the right and left waterproof doors is released. The power is restored, and the right and left waterproof doors are closed due to the tsunami force flowing into the narrow space between the high seawall wall 5 and the waterproof door.

  After the center hole 17 on the bottom surface of the left and right main shafts 9 supporting the left and right waterproof doors 8 is pushed up by a hydraulic jack 18 or the like, a gap is formed at the bottom of the outer ring 15 of the left and right swirl ball screws 13 and 14. By rotating the left and right main shafts on this, the left and right waterproof doors can be opened by applying a small force.

  With the development of the sluice gate of the present invention, it is possible to build a high tide bank for tsunami countermeasures in the river and provide a large sluice, open for boat passage during normal times, and immediately close automatically when the tsunami increases, etc. The sluice is connected horizontally, and a gear 10 is attached to the upper part of the main shaft 9 of each waterproof door, and the sluice can be closed simultaneously by meshing with the gear of the adjacent sluice. The width can be accommodated, and the entrance of a small fishing port can be closed, reducing damage caused by increased water.

As an example of an embodiment of the present invention, a plan view when the sluice gate is opened AA sectional view of FIG. BB sectional view of FIG. As an example of an embodiment of the present invention, a cross-sectional enlarged view of the left main shaft when the left waterproof door is opened when the left upper bearing of the sluice has a structure of a left vine ball screw Same as above, enlarged cross-sectional view of the left spindle when the left waterproof door is closed Same as above, with the left main door and hydraulic jack pushed up while the left waterproof door is closed Cross-sectional enlarged view when the left waterproof door is opened during a rush with the hydraulic jack

  In the sluice structure installed between the left and right high seawalls, the present invention attaches the upper bearings 11 to the left and right pillars 7 of the outer frame of the double sluice gate installed along the left and right walls 5 of the seawall. Thus, the main shaft 9 of the waterproof door 8 is suspended by this bearing, and held vertically by the lower bearing 19, and the left upper bearing 11 is structured as the left swirl ball screw 13 and the right upper bearing 12 is swollen as the right swirl. With the structure of the ball screw 14, the heavy left and right waterproof doors 8 are lowered along the screw surface by their own weights, and this rotational force is intended to rotate leftward or rightward in the direction of closing the waterproof door. The left and right waterproof door fixing devices 21 are fixed by engaging the protrusions 24 attached to the floating body support rod 23 and the waterproof door fixing latch (20).

  When a tsunami or the like is pushed, the floating body 22 of the waterproof door fixing device 21 is lifted, and the floating body support rod 23 is also lifted, and the protrusion 24 attached thereto is detached from the fixing door 20 for the waterproof door. The above-mentioned rotational force is restored, and the waterproof doors on the left and right are closed due to the tsunami force flowing into the space between the high seawall wall 5 and the waterproof door. become.

  4 to 7, the left upper bearing 11 of the left main shaft 9 of the left waterproof door has the structure of the left swirl ball screw 13, and the left waterproof door is pushed up by a hydraulic jack 18 during opening, closing and closing. It is a cross-sectional enlarged view which shows the action | operation when this is opened inside.

  When the left and right swirl ball screws 13 and 14 are used for the left and right upper bearings 11 and 12, in order to open the closed left and right waterproof doors 8, as shown in FIG. The hole 17 is pushed up by a hydraulic jack 18 or the like to create a gap at the bottom of the outer ring 15 of the left and right swirl ball screws.

  Next, as shown in FIG. 7, the main shaft 9 of the left and right waterproof doors is rotated on the center of the hydraulic jack 18. At this time, even if the main shaft is rotated, the outer ring 15 of the vine ball screw gradually descends without rotating. Therefore, the left and right main shafts 9 can be freely rotated on the center of the hydraulic jack without being subjected to the resistance by the swooping ball screws 13 and 14, and thus the right and left water-proof shafts 9 are waterproofed. The door 8 can be opened with a small force.
