Description

[Detailed description of the invention] This invention relates to a door stop device for receiving watertight rubber on both sides of a gate body of a water gate whose main purpose is tide protection.

Tide flood gates, like estuaries where rivers flow into the sea, are open during normal times and are closed only when there is danger such as a storm surge. For this reason, the door body is pulled up during normal times, and only when the door body is closed, the door body is lowered and the lower part is immersed in water. Therefore, most of the door stop that receives the watertight rubber of the lowered door body is always in contact with seawater.

FIGS. 1 and 2 show the door stop portion of a conventional flood gate, where 1 is the door body, 2 is a roller provided on the side thereof, and 3 is a watertight rubber. Reference numeral 4 denotes guide portions provided on both piers of the water gate, and receiving fittings 5 and 6 for the roller 2 are provided in the vertical direction in front and behind the guide portions. Further, in the front part of the guide part 4, a door stop metal fitting 7 with which the watertight rubber 3 comes into slidable contact is provided vertically on the surface of the pier.

In such a conventional water gate, when the water gate is closed, the water level on the sea side, that is, in the upper part of FIGS. 1 and 2, becomes high, so that water pressure from the sea side acts on the gate body 1 as shown by the arrow. At this time, the watertight rubber 3 comes into close contact with the doorstop hardware 7 to maintain watertightness and prevent seawater from flowing back into the river.

In this way, the surface of the door stop hardware 7 must be smooth in order for the watertight rubber 3 to come into close contact with the door stop hardware 7 to maintain watertightness. Sea creatures such as barnacles live on the surface of the door stop hardware 7, which creates unevenness, and when the door body 1 is lowered, the watertight rubber 3 is damaged due to these unevenness, making it difficult to maintain watertightness. This poses a serious problem in terms of flood control, making it impossible.

In order to solve such a problem, it is sufficient to remove the marine organisms attached to the surface of the door stop hardware 7, but such removal work is extremely difficult because it requires underwater work.

The purpose of this invention is to solve the above-mentioned problems, and to provide a doorstop device that prevents sea creatures from attaching to the doorstop hardware even when the door body is open.

That is, in this invention, a door stop chamber containing door stop hardware is formed in the shape of a vertical groove with an opening on the door body side, and the vertical opening of the door stop chamber has a door stop that rotates about a vertical axis. A closing member is provided to open and close this opening, and the cross-sectional shape of this closing member is a semicircle centered on the vertical axis, and a projecting portion is provided on the side of the door body so as to face the door stop chamber. provided, and on the front side of the outer end of the overhang portion, the groove-shaped doorstop projects forward into the interior of the groove-shaped doorstop,
and fixing a mounting plate along the entire length of the gate body, and in order to accommodate a closing member which rotates when the sluice gate is closed and avoids an overhang that descends with the sluice gate, an inner surface of said mounting plate and an overhang are provided. A notch is formed on the side of the door body and is open at the front, and the front edge of the mounting plate is provided with watertight rubber that tightly contacts the door stop hardware. The mounting plate is provided along the entire length thereof, and furthermore, scraping plates are provided on both sides of the opening of the doorstop chamber to scrape off accretions on the outer surface of the semicircular closing member, and scraping plates are provided on the outer surface of the closing member in the closed position. It is equipped with a watertight rubber that fits tightly.

Since the doorstop device of this invention has the above-mentioned configuration, when the door body is pulled up to open the water gate, the closing member is placed in the closed position, so that the watertight rubber on both sides of the opening of the doorstop chamber closes around the outer periphery of the closing member. Seawater does not flow into the groove-shaped doorstop interior. However, before the closing member was closed, that is, until the door was pulled up, seawater had entered the doorstop chamber, so even if the doorstop chamber was closed with the closing member, seawater remained inside, but the new Seawater cannot enter the doorstop, so sea creatures cannot enter the doorstop.

In addition, if it becomes necessary to lower the door body, by placing the closing member in the open position and opening the opening of the door stop chamber, the watertight rubber of the door body will descend into the door stop room without any hindrance and will tightly contact the door stop hardware. can be kept watertight.

An example of this invention is shown below in Figures 3 to 5.
This will be explained based on the diagram.

In these figures, 11 is a door body, and 12 is a roller provided on the side thereof, and this roller 12 is attached to the outside of a projecting portion 13 on the side of the door body 11.

Reference numeral 14 denotes a guide portion for guiding the raising and lowering of the door body 11, which is provided on a pier on the side of the door body, and receiving fittings 15 and 16 for the roller 12 are provided in the vertical direction in front and behind the guide portion.

18 is a door stop chamber provided on the side of the bracket 15;
The door body 11 side is an opening 19. 20 is a vertical shaft provided at the center of the opening 19, and a closing member 21 is fixed to this shaft 20. This closing member 21
The cross-sectional shape of is a semicircle centered on the axis 20,
Scraping plates 22 and 23 are fixed over the entire length on both sides of the opening 19 for scraping off accretions from the outer peripheral surface of the member 21.

Furthermore, rubber 24 and 25 that closely adheres to the outer peripheral surface of the closing member 21 are fixed to the inside of each of the scraper plates 22 and 23.

A forward-facing mounting plate 27 is fixed to the front side of the outer end of the overhang portion 13 over the entire length of the door body 11, and a door stop hardware 28 in the door stop chamber 18 is attached to the front edge of this mounting plate 27.
Attach watertight rubber 29 over the entire length.

A front-open area consisting of the inner surface of the mounting plate, the front surface of the overhang, and the side surface of the door body facing the mounting plate is for accommodating a closing member to be avoided when the mounting plate is lowered when the water gate is closed. It is formed as a notch on the side of the door body.

As shown in FIG. 5, the vertical shaft 20 is rotatably supported at its lower end by a bearing 32 provided on the water bottom 31, and its upper end is supported by bearings on a machine box 35 on support stands 34 provided on both sides of the water gate. Rotatably supported. This machine box 35 has a drive device 3 for the shaft 20 that is manually operated by a handle or powered by a motor.
6 will be provided.

Although it is not clear in the drawings, the lower end of the door body 11 is provided with watertight rubber that comes into contact with the gasket seat at the bottom of the water when it is lowered, and the lower end of the closing member 21 is also provided with watertight rubber that comes into close contact with the seat at the bottom of the water. Further, in the illustrated example, the closing member 21 has a semi-cylindrical shape, but the portion other than the outer semi-circular portion may be a simple frame member.

In the above embodiment, FIG. 3 shows the normal state, and at this time the opening 19 of the door stop chamber 18 is closed by the closing member 21. At this time, the door body 11
is pulled up further above the upper end of the closing member 21.

Further, in the above-mentioned closed state, seawater is prevented from entering the door stop chamber 18 by the left and right watertight rubbers 24 and 25 and the watertight rubber at the lower end of the closing member 21. However, since the seawater from when the opening 19 was open remains, seawater has entered the doorstop chamber 18, but there is no risk of seawater from outside entering, and no marine life can enter. There is no risk of the lily pads attaching to the doorstop hardware 28 and growing. In this case, a fresh water supply port is provided at the bottom of the door stop chamber 18, and after the opening 19 is closed with a closing member 21, fresh water is supplied into the door stop chamber 18.
It is even more effective if you fill the inside with fresh water.

Next, when closing the water gate, the vertical shaft 20 is rotated to the left as shown in FIG. 3 by manual or power operation, and the closing member 21 is stopped at the position shown in FIG. 4.

In this state, the opening 19 is opened and the closing member can be accommodated in the notch of the door body without becoming an obstacle to the lowering of the mounting plate attached to the door body, so the door body 11 is lowered. Then, the mounting plates 27 on both sides descend into the opening 19, and the watertight rubber 29 at the front comes into close contact with the doorstop hardware 28, but at this time,
Since no marine life is attached to the doorstop hardware 28, watertightness is maintained completely.

Although each figure shows only the left side of the water gate, it goes without saying that similar devices are symmetrically installed on the right side.

As mentioned above, this invention provides a groove-shaped doorstop chamber in each pier, and a closing member is provided at the opening of this doorstop chamber.
Since a notch is provided on the side of the door body to accommodate the closing member, when the door body is pulled up to open the water gate, the closing member is placed in the closed position to close the doorstop room. As a result, the watertight rubber on both sides of the opening of the doorstop comes into close contact with the outer periphery of the closing member, preventing seawater from flowing into the groove-shaped doorstop. However, before the closing member closes, that is, until the door body is pulled up, seawater has entered the doorstop chamber, so even if the doorstop chamber is closed with the closing member, seawater remains inside.
Fresh seawater cannot enter, so marine life cannot enter the doorstop. Therefore, even during normal times when the door body is rising, there is no risk of marine life inhabiting the door stop interior, and there is also no adhesion on the surface of the door stop metal, and there is no risk of damage to the watertight rubber provided on the sliding door body. The fear of

In addition, when it becomes necessary to lower the door body, the closing member is rotated to open the opening of the door stop chamber, and the opening position is set so that it will not become an obstacle when lowering the mounting plate with watertight rubber. By arranging the door body in a position where it can be accommodated in the notch provided on the side of the door body, the watertight rubber of the door body descends into the doorstop room without any hindrance and slides into close contact with the doorstop hardware without any deposits, maintaining watertightness. be able to.

Furthermore, the cross-sectional shape of the closing member is semicircular and concentric with the center of rotation, and when it rotates, the scraping plates on both sides of the opening scrape off marine life on the outside of the closing member, so the closing member can be opened and closed without any problem. There are effects such as being able to do it.
