TECHNICAL FIELD OF THE INVENTION
The present invention relates to switchgear of the door body in passing ship gate installed in dam net field such as reservoirs (driftwood stop facilities).
[0002]
[Prior art]
Conventional ship gates are generally equipped with one double-sided door on each of the left and right sides. When the ship is not passing, the door opens due to wind, waves, and currents, and driftwood and garbage flow out downstream. A manually-locked passage gate, which is operated directly by hand when the ship passes through a bar or chain attached as a lock to prevent the door from opening, and locks or unlocks, and a passage gate A semi-automatic type with a drive unit and an operation control device on the top, and the lock itself can be moved by remote control remote control, and a fully automatic type that controls the opening and closing by mechanically moving the door itself by remote control remote control etc. Both types require a power supply device such as a solar cell.
[0003]
[Problems to be solved by the invention]
In order for the ship to pass through the conventional manually-locked passage gate, stop the ship once before the door, remove the bar or chain by hand, release the lock, restart the ship and push the door open. While passing through the boat gate. After the ship has passed, the door automatically returns to its original closed state with springs and weights.Confirm that the door is closed, move the ship again to the side of the door, and stop it. To lock the door.
As described above, it takes time and effort to pass through the conventional passage gate, and it is extremely difficult to perform a series of procedures while steering the ship, especially when there is only one occupant. Further, since the locking and unlocking of the door body must be performed by leaning out of the boat, there is a danger of falling water, and it can be said that there is a problem in safety.
[0004]
The fully automatic cruise gate opens and closes the door itself mechanically by operating a remote control switch, etc., from the hull, so there is little danger of falling water, etc. However, the overhead equipment such as a drive unit is large, power consumption is large, and the structure of the passage gate itself is complicated, so that the cost is very high. In order to improve the cost of the semi-automatic ship gate, especially the cost aspect, the lock unit is only unlocked and locked by operating the remote control switch. However, although the cost was reduced, a large reduction was not achieved because a control device was required. In addition, a power supply device such as a solar cell must be regularly replaced and maintained, and a running cost is incurred.
[0005]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has realized at a low cost a mechanism that allows a user to easily lock and unlock the opening of a passage gate to prevent the door from opening. The purpose of the present invention is to make it possible for a ship to pass through a cruise gate safely and quickly.
[0006]
[Means for Solving the Problems]
According to the present invention, the opening and closing locking device that does not require power such as electric power or solar power installed at a cruise gate is used to force the ship to push the door to lock and release the lock to prevent the door from being opened manually. The propulsion force is used to unlock and open the door, and the door is automatically returned to its original closed state by a spring or weight after passing the vessel, and is automatically locked and easily closed by the mechanism that closes the door. The gist of the present invention is that it can be performed in Therefore, since no operation is required on the ship without stopping the ship during navigation, even if there is only one crew member, it is possible to easily pass through the passage gate. In addition, unlike a fully automatic vehicular gate that moves the door itself or a semi-automatic vehicular gate that moves the lock part, there is no drive or control equipment on the vehicular gate, and only the opening and closing locking device is small. Therefore, the cost is extremely low as compared with the fully automatic and semi-automatic passage gates. Also, there is no need to replace the solar power supply and no maintenance is required.
In other words, according to the first aspect of the present invention, the ship opens and closes both the left and right doors (2, 3) by the force of pushing the doors, and automatically closes and locks after passing the ship. A locking / unlocking device for a door at a gate, the locking / unlocking device comprising a horizontal first hinge pin (11) and a crank arm (8) attached to a fixed arm (10) protruding from one of the doors (2). And a roller (14) at the upper end of the crank arm (8), and a second horizontal hinge pin (12) and a slide arm (9) at the other end rotatably. At the same time, a lock pin (13) is assembled with the slide arm (9) in an interlockable manner, and receives the propulsive force of the ship by the swinging motion of the roller (14) and the crank arm (8), and the movement is received by the slide arm (9). ) Through the lock pin (13) The lock pin (13) is configured to be converted into a backward movement, and is unlocked by being disengaged from a lock hole (16) formed in a lock plate (15) protruding from the other door body (3). Locking mechanism.
Further, in the invention according to claim 2, the fixed arm (10) is provided so as to protrude from the one door body (2) toward both front and rear sides, while the lock plate in which the locking hole (16) is formed. (15) and the lock pin (13) are arranged above the doors (2, 3) and below the roller (14).
