Description

  TECHNICAL FIELD The present invention relates to a laterally opened / closed gate having a structure in which an openable / closable door is opened and closed with respect to a fixed wall portion as a gate of a levee for preventing storm surges and a sluice gate for preventing flooding of a river. .

At the horizontal opening and closing gates at the opening of the seawall and at the junction of the river, the doors can be closed quickly and safely in response to emergency situations such as tsunamis caused by earthquakes, high waves caused by typhoons, and sudden floods at night. Is required.
However, the opening / closing operation of the opening / closing door is generally performed manually and requires a certain amount of time and labor, so that it cannot be handled in an emergency or may be dangerous. In particular, regarding the tsunami, the time from the occurrence of the earthquake to the attack is short, and many precious lives that were closed during the Great East Japan Earthquake have been lost.

  In order to automate the opening and closing operation of the door, in a conventional lateral opening and closing gate, for example, a driving rack gear is extended on the upper surface of the door body in the moving direction, and is driven to a dam body (fixed wall portion). A lateral pulling gate (horizontal pulling opening / closing gate) provided with a gear motor (electric motor) that rotationally drives a pinion gear is disclosed (see Patent Document 1). In this case, the gate (opening / closing door) is opened and closed by the driving force of a gear motor (electric motor) that is fixed to a fixed wall-like portion and driven by power supplied from the outside. It should be noted that a device that directly uses the driving force of the electric motor requires a large electric motor and tends to be a large-scale configuration. Since the electric motor requires external power, it cannot be driven if the external power supply fails during a large-scale disaster.

  Also, in order to respond to an emergency when opening and closing the door, it is possible to move horizontally along the guide rail and move horizontally along the guide rail to open and close the tide bank opening. In the apparatus, the tide door support means for supporting the tide door at the first position with the opening of the tide bank open, and the tide door from the first position with the opening closed. The tide door closing means includes a stopper member for fixing and supporting the tide door at the first position, and the tide door closing action means is a stopper member. When the tide door is released, the tide door includes a guide rail that inclines downward from the first position side toward the second position side so that the tide door moves by its own weight from the first position toward the second position. Emergency closing device (horizontal opening and closing gate) is disclosed That (see Patent Document 2).
