Abstract

The present invention relates to a floodgate for maintenance, where a cofferdam is constructed for maintenance of a main floodgate. The floodgate according to the present invention is provided to prevent an airtight rubber of the floodgate for maintenance from being damaged by excessive friction with a guide frame and allow rapid and accurate opening/closing of the floodgate. For this, the floodgate (20) for maintenance, which has both ends inserted into guide frames (10) in both sides for elevation guide and an airtight rubber (23) in the front side facing the rear side (11) of the guide frame (10) comprises: a first wedge member (120) is installed in the rear side of a floodgate main body (21) facing the front side (13) of the guide frame (10); and a second wedge member (130) comprising a second wedge plane (131) coming in contact with a first wedge plane (121) of the first wedge member (120). During elevation movement by an operation of an elevation driving part, the floodgate maintains a fixed gap to the front and rear sides (11, 13) of the guide frame (10). During a closed state where the operation of the elevation driving part is not applied, the first wedge member (120) and the second wedge member (130) are combined by the weight of the floodgate main body (21) and thus the gap is eliminated. Accordingly, the airtight rubber (23) provided in the front side of the floodgate main body (21) is pressurized to adhere to the rear side (11) of the guide frame (10).

Description

{Floodgate for maintenance}

The present invention relates to a repair gate for construction of a cargo film for maintenance of a hydrograph, which prevents damage to the watertight rubber of the repair gate due to excessive friction with the guide frame, This is about repair gates reinforced with a confidential structure.

Dam storage facilities, hydropower and tidal power generation facilities are equipped with hydrological facilities for controlling the water used by rivers and seawater.

If the main gate is broken, it is difficult to maintain the main gate because it is under a large water pressure. Therefore, a repair gate called "Stop-log" is installed at the front or rear of the water gate, The maintenance of the main watercraft will be carried out.

These repair gates are constructed by stacking one or several sheets according to the height of the main water gate requiring maintenance, and they block the water pressure. They are often bulky and heavy and can be lifted or lowered using the lifting crane jig .

1, the repairing gate 20 is formed in both side wall structures disposed on the front or rear of the main watercourse and both ends are inserted in the guide frame 10 for guiding the elevating movement of the repair watercourse, The water-tight rubber 23 is provided on one surface of the guide frame 10 facing the guide frame 10 so as to maintain airtightness with the guide frame 10.

The repairing water gate 20 having such a configuration is guided by the guide frame 10 in a state where both end portions are inserted into the guide frame 10 while being lifted up through the elevation driving portion (crane jig device) The repair water gates 20 are installed by repeatedly laminating a plurality of repair water gates 20 according to the height of the main water gate.

However, the following problems have been encountered in conventional repair gates.

The watertight rubber provided on the front side at the time of installation must be kept pressed against the front side of the guide frame so that the front and rear sides of the watertight door are spaced apart from each other in the front- So that it is moved up and down in a pressed state.

As a result, the repair gate is moved up and down in such a state that the guide frame is pressed against the guide frame without any clearance. This causes a problem that the water-tight rubber is damaged from the frictional resistance with the guide frame, A problem can not be secured.

In addition, since the water-tight rubber is often given its own elasticity, it is possible to maintain the contact state with the guide frame by the restoring force in the closed state of the repair watercraft. However, since the elasticity of the water- There is a problem that the fatigue life of the water-tight rubber is shortened.

In addition, as described above, the repair gate is raised and lowered in a state in which the guide frame is pressed without clearance. Thus, a large load may be generated during the elevating operation of the repair water port using the elevation driving portion, And the opening and closing time of the repair water door becomes longer.

In addition, since there is no clearance in the forward and backward directions of the guide frame and the repairing watercourse, even if the repairing watercourse is to be inserted into the guide frame while the repairing watercourse is lifted using the elevating guide, There is a problem that it takes a lot of time to set the insertion position of the door.

In addition, since there is no clearance in the forward and backward direction of the guide frame and the repairing watercourse, if there is foreign matter inside the guide frame that maintains the exposed state when the repair watercourse is not used, The watertight rubber can be further damaged by the friction due to the foreign matter and the position of the watertight door for descending becomes unbalanced, so that the repairing watertight can not smoothly fall and can be stopped.

On the other hand, if the clearance between the guide frame and the repair water receptacle is relatively large in order to solve the above-mentioned problem, the watertight rubber can not be brought into close contact with the proper pressure of the guide frame and sufficient airtightness can not be secured. In the process of lifting the multi-tier repair gates in sequence, the difference in the water pressure acting on the repair gates according to the height difference (strong water pressure acts on the repair gates located at the bottom) occurs, The more gradually the repair gates are pushed forward to the repair gates located in the vicinity of the repair gates.

In addition, the first and second wedge members 120 and 130 may be provided in a plurality of in the height direction of the hydrograph body 21.

In the present invention, when the operating force of the elevation driving portion is applied to the repair gate, the first and second wedge members are separated from each other to form a clearance with the guide frame, The first and second wedge members act as a wedge due to the weight of the water for repair at the closing time when the operating force of the lifting and lowering driving unit is removed, So that excellent airtightness between the guide frame and the watertight rubber can be secured.

Further, according to the present invention, the friction resistance of the water-tight rubber is reduced during the movement of the water for repair, and the contact state of the water-tight rubber is maintained uniformly only during the closure requiring airtightness, so that the fatigue life of the water-tight rubber can be increased.

Further, since the second wedge member and the wedge fixing block are kept in simple holding state in the holding housing, the second wedge member and the wedge fixing block are simply separated from each other and the inclination angle of the second wedge face of the second wedge member is It is possible to finely adjust the amount of forward movement of the water-repellent water by the wedge joint, and as a result, compatibility with the water-tight rubber can be easily adjusted depending on the type of the water- This is also an excellent advantage.

Further, in the present invention, when a plurality of wedge members are arranged according to the height of the repair watertight, uniform movement is realized on the upper and lower sides of the repair watertight door, By satisfying the pressing force, more excellent airtightness can be maintained.

In addition, since the first wedge member as well as the second wedge member and the wedge fixing block are coupled to the repairing gate, it is unnecessary to change the design of the guide frame, thereby improving the structure of the existing repairing gate There are advantages.
