Description

[Detailed description of the invention] This invention relates to tide gates installed at the openings of sea walls such as ports, rivers, and coasts, and is particularly useful when blocking openings during high tides or typhoons. This invention relates to a horizontally pulling type flood gate with improved rail and running rail structure.

Conventionally, this type of tide gate has generally had the embodiments shown in FIGS. 1 and 2, or the embodiments shown in FIGS. 3 and 4.

In the figure, 1 is the seawall, 2 is the opening created by cutting out the seawall 1, 3 is the seawall door that opens and closes the opening 2, 4 is the wheel for movement, and 5 is when the seawall door 3 closes the opening 2. Tide gate door 3
6. Up and down movement means for lowering the water to improve water quality.
is the upper roller, 7 is the side guide roller, 8 is the tide gate door 3
Water gas packing attached to the lower periphery, 9 is a running rail of the moving wheels 4, 10 is a stopper fitting when the tide gate door 3 is closed, 11 is a top rail on which the upper roller 6 is guided, 12 is a tide gate door 3 This is the storage section.

In the former case, the running rail 9 protrudes from the ground surface 13 at the opening 2 of the seawall 1, and the moving wheels 4 with flanges run on this running rail 9. 3. There are problems such as a lot of vibration and noise during movement.

Further, if the running rail 9 protrudes from the ground surface 13, it not only poses an obstacle when a working vehicle passes through the opening 2, but also becomes an obstacle at a landing place such as a fishing port.

Further, there were other problems such as the difficulty in completely keeping the watertight packing 8 on the sides of the running rail 9 and the tide gate 3 clean.

In addition, the running rail 9 in the latter is buried on the same plane as the ground surface 13, and two sets of upper and lower side guide rollers 7 attached to the rear of the seawall door 3 are guides buried in the wall surface of the seawall 1. Although it is of a type that is guided by a rail 7a, the structure of the side guide roller 7 and the guide rail 7a portion that guides the guide roller 7 is complicated, and there are many problems such as difficult installation work.

This invention was made in order to solve the problems in the conventional structure described above, and an embodiment of this invention will be specifically described below with reference to FIGS. 5 to 7.

In the figures, parts corresponding to those in the conventional embodiment will be described with the same reference numerals.

A flat rail 9 on which the moving wheels 4 of the tide gate 3 run is buried in the opening 2 of the sea wall 1 on the same plane as the ground surface 13, and a tide barrier is installed on the lower surface of the storage section 12 of the tide gate 3. A lower guide roller 15 of a guide portion 14 protruding from the rear of the gate 3 and a revolving lower rail 16 on which the moving wheels 4 run are laid.

The guide part 14 remains in the storage part 12 with the tide gate door 3 closed, and the upper roller 6 attached to the upper surface of the guide part 14 is guided by the top rail 11 to prevent the tide gate door 3 from falling.

Further, the lower guide roller 15 is attached below the guide portion 14 so as to be guided by the side wall of the b-shaped lower rail 16.

In the figure, 17 is a mounting member that supports the top rail 11 on the top surface of the seawall 1, 18 is a reinforcing member that supports the running rail 9 and the lower rail 16, and 19 is a door body when the seawall door 3 is closed in the opening 2. The door stop 8a transmits the water pressure to the sea wall 1, and 8a is a vertical packing serving as a water packing between the tide gate door 3 and the door stop 19.

In order to operate the horizontally pulling type tide gate 3 configured as described above in detail, first, the tide gate 3 is normally stored in the storage section 12 of the sea wall 3.

At this time, the moving wheels 4 and the lower guide roller 15 are located within the square-shaped lower rail 16, the upper roller 6 is housed within the top rail 11, and the tip of the door body is the same as the side surface of the seawall 1. Or located slightly inward.

Next, when moving the door body to close the opening 2, the tide gate door 3 is moved until its tip abuts against the stopper fitting 10.

In this case, the upper roller 6 and lower guide roller 15 of the guide section 14 provided at the rear of the door are in sliding contact with the top rail 11 and the b-shaped lower rail 16, respectively, so that the door does not fall.

Next, when the opening 2 is completely closed, the vertical movement means 5 of the moving wheels 4 is operated to lower the gate body of the tide gate door 3, and watertightness is maintained by the water seal 8 attached to the lower circumference of the gate body. installed in a state where

Finally, watertightness is maintained via the vertical packing 8a by pulling the seawall door 3 toward the seawall 1 side using a tightening fitting (not shown) or the like. Second, the opening 2 is closed.

Further, when opening the tide gate door 3 and storing the door body in the storage section 12, the above-mentioned operation order may be reversed.

Therefore, the tide gate according to this invention has the following effects.

(1) Since running rails etc. cannot be installed protruding from the opening of the embankment and it is flush with the ground surface, there is no obstruction to the passage of work vehicles or the landing of ships.

(2) Since the lower rail of the storage section is chevron-shaped, the side wall on the seawall side can be used as a reference surface during installation, and the side wall on the sea side helps prevent dirt, sand, and garbage from entering, and provides a good running surface. It will be done.

(3) It is possible to standardize tide gates, doorstops, and other parts, which reduces processing man-hours and simplifies construction, which is also economically effective.

(4) There is no need for special construction on the seawall, and construction can be done easily.

(5) The movement of the tide gate is smooth, there is less vibration and noise, and the water resistance is further improved than with conventional structures.
