Abstract

PURPOSE:To simplify maintenance of a sluice door by installing a L-shaped arm provided with a removing plate on its door as well as a weight slidable up and down, both of which are pin-connected idly to each other, and by removing an attachment on a door stop face interlocking with closing action of the door. CONSTITUTION:An L-shaped arm 4 provided with a removing plate 7 with a blade 8 in the edge is pivotally installed in a bottom plate 3 at a curving point 5, and is attached thereto in pin connection through a bracket with a weight 13 installed slidably up and down and with a long hole 12. The bottom plate 3 is attached to a sluice door 2 in the predetermined position. When the sluice door 2 is closed, an attachment such as a barnacle on a watertight cushion rubber working door stop face 1 is removed by means of the blade 8 of the removing plate 7. If a gap H is defined as zero, the removing plate 7 is separated from the door stop face 1. Maintenance of a sluice door can thus be simplified.

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial field of application The present invention relates 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.

(0) Conventional technology At times, the gate body is raised above the water surface and left in the open state, and during high tide, the gate body is lowered and closed to prevent tide water from flowing upstream. In such cases, crustaceans such as Fujibbo, shellfish, and other foreign substances 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 cases, the drawback was that it required troublesome special work by divers and was expensive.

(c) Problems to be Solved by the Invention The present invention uses a watertight rubber stopper attached to a water gate and embedded in concrete to remove crustaceans such as Fujitbo, 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. The L-shaped arm is movably attached, and the watertight rubber door of the arm is attached to the tip of the arm piece on the door contact side and extends in substantially the same direction as the arm piece. A removal plate in contact with the abutment surface, a rotation 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 above-mentioned folding type 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.

(f) Example Hereinafter, the configuration of an example of the present invention will be explained 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 door 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 T-shaped arm 4 is attached to a predetermined position of a mounting plate 3 fixed to a predetermined position of the water gate body 2 so as to be rotatable at a bending portion 5 thereof. In this case, the sliding type arm 4 has a long arm piece 6 on the watertight rubber door stop surface 1 side that is longer than the opposite side, with the bending part 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 arm piece 6, and a blade part 8 that contacts the watertight rubber doorstop surface 1 is attached to the tip of the removal plate 7. It is formed. The distal end of the removal plate 7 rotates inward around the attachment position of the removal plate 7 through a blade stopper screw 9 screwed into the bent portion 5 side of the long arm 6 from the attachment portion thereof. is being prevented. The tip end of the short arm 10 side of the above-mentioned arm 4 is slidably fitted into a long hole 12 bored 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 a guide body 1 fixed at a predetermined position of the door body 2.
4 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 a watertight rubber attached to the door body 2 to maintain watertightness between the watertight rubber and the door stop surface 1, and 16 is a number of surfaces.

(to) action Next, the action 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 surface 16, a short L-shaped arm 4 is attached to the tip of the removal plate 7. The weight body 13 loaded on the tip end of the arm 10 exerts a rotational moment that presses the watertight rubber door contact surface in one direction via the L-shaped arm 4. 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 descends, the tip of the blade part 8 slides while contacting the surface of the watertight rubber door stop surface 1. The deposits on the water gate are automatically removed in conjunction with the closing operation of the water gate prior to passing through the gate body.

When the tip of the removal plate 7 reaches near the surface 16, the lower end of the weight body 13 reaches the surface 16, but the lower edge of the water gate body 2 is at a height of a distance H from the surface 16. descending to the position. Therefore, as shown in FIG. 2, when the water gate body 2 is further lowered to the position of the number plane 16, the weight body 1 loaded on the tip of the short arm 10 side of the L-shaped arm 4 is removed.
When the load is released, 3 is guided by the guide body 14 fixed to the door body 2 by a length corresponding to the distance H, and relatively rises to the tip of the short arm 10 of the sliding arm 4. A rotational moment is applied which pushes the part upward and rotates the long arm 6 of the fitting arm 4 in a direction away from the watertight rubber door stop surface 1. In this way, the long arm 6
is rotated in the direction away from the watertight rubber door stop surface 1, so that the removal plate 7 rotates around its mounting position and its tip side as a fulcrum, and becomes parallel to the plane 16. 617 example, 77 has a reed contact surface 1h)
The object is moved along the surface 16 by a certain distance.

As a result, the removing plate 7 is removed from the surface of the watertight rubber 15 that descends as the water gate body 2 descends to several planes 16.
i! ! , avoid it.

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) As explained in detail, this invention allows for the use of watertight rubber parts that are attached to water gate doors and embedded in concrete. This system can automatically remove the deposits of the water gate in conjunction with the closing operation of the water gate before it passes through the gate body, thereby ensuring the watertightness of the water gate and simplifying the maintenance and management of the water gate. In addition, it is extremely rational and economically superior as it can significantly reduce management costs.
