Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention is directed to a watertight rubber stopper that is attached to a water gate and is embedded in concrete. This invention relates to a device for removing deposits on the side watertight rubber contact surface of a water gate door, which is capable of automatically removing deposits in conjunction with the closing operation of the water gate door.

(b) Conventional technology A flood gate, etc. whose gate body is normally kept open above the water surface and lowered during high tide to close it to prevent tide water from flowing upstream. In this case, crustaceans such as barnacles, shellfish, and other foreign matter may adhere to the side rubber door stop surface and damage the rubber, making it impossible to maintain watertightness. In order to prevent this, it is recommended to have a diver go to the site about once a month to check for the presence of crustaceans, molluscs, and other foreign matter, and to remove them if they are found. Necessary for conservation purposes. Therefore, in such a case, there was a drawback that it required troublesome special work by the diver and required a lot of cost.

(c) Problems to be Solved by the Invention The present invention provides a watertight rubber stopper attached to a water gate and embedded in concrete to remove crustaceans such as barnacles, shellfish, and other deposits that adhere to the door stop surface of the water gate. Watertight rubber door stop surface on the side of a water gate that can ensure watertightness and simplify the maintenance and management of the water gate by automatically removing it in conjunction with the closing operation of the door prior to the passage of the gate body. The purpose is to obtain a deposit removal device.

(d) Means for Solving the Problems The present invention has been made by focusing on such conventional problems. an L-shaped arm that is movably attached; and a watertight rubber door that is attached to the tip of the arm piece on the side of the watertight rubber door stopper side of the L-shaped arm and extends in substantially the same direction as the arm piece. a removal plate in contact with the abutment surface; a rotational direction regulating means for preventing the distal end side of the removal plate from rotating inward about the mounting position of the removal plate; and one distal end portion of the other arm of the L-shaped arm. A weight body connected via a bracket that slidably fits into a long hole drilled in the horizontal direction, and a guide body fixed to the door body for guiding the weight body in the vertical direction. It is an object of the present invention to provide a device for removing deposits on the side watertight rubber contact surface of a water gate door, which is constructed of the following.

(E) Embodiment Hereinafter, the configuration of an embodiment of the present invention will be described with reference to the drawings.

A watertight rubber door contact surface 1 embedded in concrete is provided on the side of the water gate. A water gate body 2 is provided which opens and closes the water gate by moving up and down along a watertight rubber door contact surface 1 of the water gate. A downwardly bent L-shaped arm 4 is rotatably attached to a predetermined position of a mounting plate 3 fixed to a predetermined position of the water gate body 2 at a bent portion 5 thereof. In this case, the L-shaped arm 4 has a long arm piece 6 which is longer on the watertight rubber door contact surface 1 side than on the opposite side, with the bent portion 5 as the center. A removal plate 7 extending in substantially the same direction as the arm piece 6 is attached to the tip of the piece 6, and a blade portion 8 that contacts the watertight rubber doorstop surface 1 is formed at the tip of the removal plate 7. has been done. The distal end of the removal plate 7 is rotated inward about the mounting position of the removal plate 7 by a blade stopper screw 9 screwed into the bent part 5 side of the long arm 6 from the mounting part. blocked. The tip of the L-shaped arm 4 on the side of the short arm 10 is slidably fitted into an elongated hole 12 drilled in the horizontal direction of a bracket 11, and the bracket 11 is fixedly connected to a weight body 13. The weight body 13 is supported by a guide body 14 fixed at a predetermined position of the door body 2 so as to be slidable in the vertical direction. In this case, it is necessary to extend the door stop so that the blade part 8 does not come off the door stop even when the door body 2 reaches a high position. In addition, 15
is attached to the door body 2 and the watertight rubber door stop surface 1
Watertight rubber for maintaining watertightness between
is the floor surface.

(F) Effect Next, the effect will be explained.

As shown in FIG. 1, from the open position where the water gate body 2 is lifted upward until the tip of the removal plate 7 contacts the floor surface 16, an L-shaped arm 4 is attached to the tip of the removal plate 7.
A weight body 1 loaded on the tip of the short arm 10 of
3, a rotational moment is applied via the L-shaped arm 4 to press the watertight rubber door in one direction. However, since the distal end of the removing plate 7 is prevented from rotating inward around the mounting position, the distal end of the blade 8 of the removing plate 7 is securely attached to the doorstop surface 1 by the watertight rubber. come into contact with Therefore, as the door body 2 is lowered, the tip of the blade part 8 slides while contacting the surface of the watertight rubber doorstop surface 1, so that crustaceans such as barnacles and seashells attached to the surface 1 are removed. and other deposits are automatically removed prior to passing through the gate body in conjunction with the closing operation of the water gate door.

When the tip of the removal plate 7 reaches near the bottom surface 16, the lower end of the weight body 13 reaches the bottom surface 16, but the lower edge of the water gate body 2 is at a distance H from the bottom surface 16.
It has descended to a height of . Therefore, as shown in FIG. 2, the water gate body 2 is further
When the weight body 13 is lowered to the position shown in FIG. The tip of the short arm 10 of the L-shaped arm 4 is pushed upward, and the long arm 6 of the L-shaped arm 4 is moved to the watertight rubber door stop surface 1. A rotational moment acts to rotate it in the direction away from. In this way, as the long arm 6 is rotated in the direction away from the watertight rubber door stop surface 1, the removal plate 7 rotates about its mounting position and its tip side as a fulcrum. The watertight rubber door is tilted in a direction parallel to the floor surface 16 and moved by a distance L from the door stop surface 1 along the floor surface 16. Thereby, the watertight rubber 1 that descends as the water gate body 2 descends to the floor surface 16 removes the removal plate 7.
5 has been previously escaped from the surface.

On the other hand, the movement of the water gate body 2 from the downwardly moved closed door position to the open door position is performed in the opposite manner to the movement from the open door position to the closed door position.

(g) Effects of the invention As explained above, according to this invention,
A watertight rubber stopper attached to the water gate and embedded in concrete works in conjunction with the closing operation of the water gate to remove crustaceans such as barnacles, shellfish, and other deposits that adhere to the door stop surface, always ahead of the passage of the gate body. Since it can be automatically removed by water, it is extremely rational and economically superior, as it ensures the watertightness of the water gate, simplifies the maintenance and management of the water gate, and significantly reduces management costs. .
