Abstract

The present invention discloses an adjustable movable side water seal device for a bottom shaft driven steel gate, which includes a fixed structure and a movable structure. On the one hand, through the large elastic deformation of the L-shaped water seal itself, it tightly adheres to the working surface of the water seal seat plate. On the other hand, by adjusting the bolts and adjusting threaded pipes, the inner and outer L-shaped water seals and the inner and outer angle steel pressing plates move within the waist-shaped holes of the water seal installation steel plate, so that the water seal tightly adheres to the working surface of the water seal seat plate. The low compression force and low friction resistance of the L-shaped water seal enable the movable structure of the present invention to be easily pulled out or put into the fixed structure, and the limit plate and gland can effectively limit the movement of the movable structure within the fixed structure. The present invention is simple to manufacture, low in cost, easy to adjust, and no water retaining facilities are required for disassembly and replacement. Therefore, the maintenance cost of the side water seal of the bottom shaft driven steel gate, especially the large-span bottom shaft driven steel gate, is greatly reduced.

Description

Technical Field

[0001] The present invention relates to a side water seal device for hydraulic steel gates, and particularly to an adjustable movable side water seal device for a bottom - shaft - driven steel gate, which is applicable to the overhaul and replacement of the side water seal device of a bottom - shaft - driven steel gate. It is especially applicable to the overhaul and replacement of the side water seal of a large - span bottom - shaft - driven steel gate without a water - retaining overhaul facility. The side water seals of other types of large - span gates can also be used for reference. Background Art

[0002] At present, the side water seals of bottom - shaft - driven steel gates are mostly fixed. For large - span bottom - shaft - driven steel gates, since it is difficult to implement overhaul water - retaining facilities, the side water seal devices of large - span bottom - shaft - driven steel gates are difficult to replace, and the maintenance cost is very high. At present, there are mainly two types of plug - and - play water seal devices used on a small number of bottom - shaft - driven steel gates: One is to adjust the relative position of the side water seal and the water seal seat plate embedded in the concrete through a wedge block to compensate for the errors caused by manufacturing and installation, so as to meet the water seal compression amount required by the design. The required wedge jacking device itself cannot be disassembled for overhaul and has problems of corrosion and damage; the other is to adjust the relative position of the side water seal and the water seal seat plate embedded in the concrete by adjusting the thickness of the rubber cushion plate to compensate for the errors caused by manufacturing and installation, so as to meet the water seal compression amount required by the design. The common point of these two plug - and - play water seal devices is to pre - compress the front and rear P - type water seal rubbers in a fixed frame to achieve the water - stopping effect. Therefore, the water seal friction resistance is large, the adjustment is difficult, and even it is difficult to adjust, resulting in the water - stopping effect of the gate not meeting the design requirements. And because the water seal friction resistance is large, it is difficult to extract and insert the side water seal device. The use effects of these two types are not ideal enough in engineering practice, and the operation is not convenient enough. Summary of the Invention

[0003] In order to overcome the defect that the existing side water seal device cannot meet the requirements of bottom - shaft - driven steel gates, especially the side water seal of large - span bottom - shaft - driven steel gates is difficult to overhaul and replace, the present invention provides an adjustable movable side water seal device for a bottom - shaft - driven steel gate to solve the problems of difficult overhaul and replacement and high maintenance cost of the side water seal of bottom - shaft - driven steel gates, especially large - span bottom - shaft - driven steel gates.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] An adjustable movable side water seal device for a bottom - shaft - driven steel gate includes a fixed structure and a movable structure. The fixed structure is welded to the bottom shaft and the gate leaf, and the movable structure is placed inside the fixed structure;

[0006] The fixed structure includes a fixed U-shaped frame, rib plates, gland, and stainless steel fasteners for the fixed structure. The rib plates are welded on both sides of the fixed U-shaped frame. The gland is connected to the fixed U-shaped frame through the stainless steel fasteners for the fixed structure, and a rectangular hole is provided on the gland. The movable structure includes a water seal mounting steel plate, bottom water seal, inner double L-shaped water seal, outer double L-shaped water seal, inner angle steel pressing plate, outer angle steel pressing plate, limit plate, stainless steel fasteners for the movable structure, adjusting bolts, and adjusting threaded pipes. The inner angle steel pressing plate and the inner double L-shaped water seal are fixed on the water seal mounting steel plate through the stainless steel fasteners for the movable structure, and the outer angle steel pressing plate and the outer double L-shaped water seal are fixed on the water seal mounting steel plate through the stainless steel fasteners for the movable structure. Limit plates are welded to the top and bottom ends of the inner angle steel pressing plate and the outer angle steel bottom plate respectively. The adjusting threaded pipes are evenly distributed on the inner angle steel pressing plate and the outer angle steel pressing plate, and the adjusting bolts are fitted and tightened with them. The bottom water seal is connected to the bottom of the water seal mounting steel plate. The top of the water seal mounting steel plate is in the shape of a lifting lug and is provided with a lifting lug hole, and a hole is provided on the side of the water seal mounting steel plate.

[0007] The movable structure is placed into the fixed U-shaped frame of the fixed structure through the lifting lug hole on the water seal mounting steel plate. The lifting lug of the water seal mounting steel plate passes through the rectangular hole of the gland, and the gland is tightened through the stainless steel fasteners for the fixed structure, so that the bottoms of the outer double L-shaped water seal, inner double L-shaped water seal, and bottom water seal of the movable structure are pressed tightly against the bottom shaft.

[0008] Preferably, the included angles of the outer double L-shaped water seal and the inner double L-shaped water seal in the free state are each 100°, and the included angles in the theoretical installation state should be each 90°. The displacement of the cantilever sections of the inner and outer double L-shaped water seals is used to compensate for the errors caused by manufacturing and installation, so that the outer double L-shaped water seal and the inner double L-shaped water seal are closely attached to their respective water seal seat plates, achieving a good water stop effect.

[0009] Preferably, the holes on the side of the water seal mounting steel plate are processed into waist-shaped holes, and the distance between the outer double L-shaped water seal and the inner double L-shaped water seal is adjusted by adjusting the positions of the stainless steel fasteners for the movable structure between the waist-shaped holes, so as to adjust and compensate for the errors caused by manufacturing and installation, so that the outer double L-shaped water seal and the inner double L-shaped water seal are closely attached to their respective water seal seat plates, achieving a good water stop effect.

[0010] Preferably, one limit plate is provided at the top and bottom ends of the inner angle steel pressing plate and the outer angle steel pressing plate respectively to limit the displacement of the movable structure in the fixed structure along the water flow direction.

[0011] Preferably, the side of the fixed U-shaped frame is welded to the web of the side beam of the water stop door leaf of the bottom shaft-driven steel gate, and the bottom of the fixed U-shaped frame is welded to the bottom shaft of the bottom shaft-driven steel gate.

[0012] Preferably, after adjusting the matching dimensions of the adjusting bolt and the adjusting threaded pipe to adjust the required distance between the outer double L-shaped water seal and the inner double L-shaped water seal, the movable structure is placed inside the fixed U-shaped frame. The gland is fixedly installed on the top of the fixed U-shaped frame by the stainless steel fasteners of the fixed structure. At this time, the bottom of the movable structure is tightly attached to and pressed against the bottom shaft of the bottom shaft-driven steel gate. The outer double L-shaped water seal is tightly attached to the water stop seat plate buried in the concrete, and the inner double L-shaped water seal is in close contact with the inner side surface of the fixed U-shaped frame, thereby forming continuous water stop and meeting the water stop requirements of the gate.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The holes on the side of the water seal installation steel plate are waist-shaped holes. The distance between the inner and outer double L-shaped water seals can be adjusted by the adjusting bolt and the adjusting threaded pipe, so as to ensure that the water seal can be tightly attached to its respective water stop seat plate;

[0015] 2. The device of the present invention effectively utilizes the advantages of the inner and outer double L-shaped water seals, such as large deformation, strong error compensation ability, small compression force and thus small frictional resistance. Only a small force is required to easily take out or put in the movable structure;

[0016] 3. The device of the present invention makes the replacement of the side water seal of the bottom shaft-driven steel gate, especially the large-span bottom shaft-driven steel gate, easy and convenient, increases the operation safety of the large-span bottom shaft-driven steel gate, and can significantly reduce the construction cost of replacing the side water seal of the large-span bottom shaft-driven steel gate.

[0027] The holes on the side of the water seal installation steel plate 2a are processed into waist-shaped holes, and the distance between the outer double-L-shaped water seal 2b and the inner double-L-shaped water seal 2c is adjusted by adjusting the position of the movable structure stainless steel fastener 2f between the waist-shaped holes; the adjusting threaded pipe 2g is welded to the inner angle steel pressing plate 2e, and the distance between the outer double-L-shaped water seal and the inner double-L-shaped water seal 2c is adjusted by the adjusting bolt 2h and the adjusting threaded pipe 2g to adjust the compression amount of the water seal, so that the outer double-L-shaped water seal and the inner double-L-shaped water seal 2c are closely attached to their respective water seal seat plates, achieving a good water stop effect.

[0028] Limit plates 2i are respectively welded to the top and bottom ends of the inner angle steel pressing plate 2e and the outer angle steel pressing plate 2d to limit the movable structure 2 from moving in the upstream and downstream directions within the fixed structure 1.

[0029] The top of the water seal installation steel plate 2a passes through the rectangular hole of the gland 1d to limit the movement of the movable structure 2 in the direction perpendicular to the water flow.

[0030] Through the above implementation method, the outer double-L-shaped water seal 2b is closely attached to the water stop seat plate buried in the concrete, the inner double-L-shaped water seal 2c is closely attached to the inner side surface of the fixed U-shaped frame 1a, and the bottom of the outer double-L-shaped water seal 2b, the bottom of the inner double-L-shaped water seal 2c, and the bottom water seal 2j are closely attached to the bottom shaft 3 under the pressure of the gland 1d, thus ensuring the continuity of the side water stop of the bottom shaft-driven steel gate and meeting the water stop requirements of the gate.
