Description
Technical Field
The invention relates to a plane steel gate of hydraulic and hydroelectric engineering, in particular to a pressurizing supporting plane steel gate applied to a large orifice and a high water head.
Background
The gates used in the existing hydraulic and hydroelectric engineering are all traditional sliding bearings or rolling bearings (the rolling bearings comprise fixed wheel bearings, chain wheel bearings and the like). The sliding bearing has higher friction coefficient and is not suitable for large-orifice and high-head gates; although the fixed wheel support is suitable for large-orifice and high-head gates, the fixed wheel support has limited load, large workload of manufacture and installation, complex technical process, large reserved space of a gate slot and complex structure of an embedded part; the chain wheel support is a rolling support form which is suitable for a large hole and can bear ultrahigh water head, but because the chain wheel support has extremely strict requirements on manufacturing, installation and maintenance and is very expensive in manufacturing cost, only a few chain wheel support projects are adopted in China at present.
Disclosure of Invention
The invention aims to provide a pressurizing supporting type plane steel gate which is high in supporting load and suitable for large orifices and high water heads.
In order to achieve the purpose, the invention can adopt the following technical scheme:
the invention relates to a pressurizing support type plane steel gate, which comprises a steel gate body arranged in a gate groove, wherein a plurality of pairs of pressurizing supports are arranged on the back water surface of the steel gate body and close to the left side edge and the right side edge along the height direction of the steel gate body, the pressurizing supports are box-shaped structures with outward openings, and the opening edges of the pressurizing supports are attached to a track fixedly arranged on the inner side wall of the gate groove to form a water storage cavity; a pressurizing main pipe horizontally penetrating from the upstream surface of the steel gate body is arranged on the steel gate body, and the pressurizing main pipe is respectively communicated with the water storage cavity through pressurizing branch pipes extending towards two sides; the main pressurizing pipe is provided with a pressurizing water pump, and each main pressurizing pipe is provided with a flow regulating valve.
The opening edge of the pressurizing bearing is fixedly provided with an annular clamping plate, a support adjusting block attached to the rail is arranged on the annular surface close to the inner side of the annular clamping plate, the support adjusting block is movably arranged in a clamping groove formed between the annular clamping plate and the pressurizing bearing, and a water-blocking sealing ring is arranged on the attaching surface of the support adjusting block and the bottom of the clamping groove.
The invention has the advantages of simple structure, low cost, simple and convenient installation and use, low maintenance cost and greatly reduced opening and closing force when the steel gate body runs. The upstream water of the steel gate body is pressurized by the pressurizing water pump, the pressurizing main pipe and the pressurizing branch pipe and then is conveyed to the water storage cavity formed between the pressurizing support and the track to form a high-pressure water chamber, and the reaction force of high-pressure water to the track acts on the steel gate body, so that the upstream water pressure of the steel gate body is resisted, the pressure between the track and the pressurizing support is reduced, the sliding frictional resistance between the steel gate body and the side wall of the gate slot in the operation process is greatly reduced, the steel gate is suitable for large-hole openings and high-water-head gates, and the opening and closing force of the gate is greatly reduced.

Detailed Description
As shown in fig. 1-3, the pressurizing support type plane steel gate of the present invention comprises a steel gate body 2 arranged in a gate groove 1, wherein a plurality of pairs of pressurizing supports 3 are arranged on the back surface of the steel gate body 2 near the left and right side edges along the height direction, and the pressurizing supports 3 are box-shaped structures with outward openings; the opening edge of the pressurizing support 3 is attached to a track 4 fixedly arranged on the inner side wall of the gate slot 1 to form a water storage cavity 5, the track 4 is an embedded part embedded in concrete of the gate slot 1, and a stainless steel plate is attached to the surface of the track 4; a main pressurizing pipe 6 horizontally penetrating from the upstream surface of the steel gate body 2 is arranged on the steel gate body, and the main pressurizing pipe 6 is respectively communicated with the water storage cavity 5 through a main pressurizing branch pipe 7 extending towards two sides; a pressurizing water pump 8 is arranged on the pressurizing main pipe 6, and a flow regulating valve 9 is arranged on each pressurizing branch pipe 7. When the gate needs to be opened and closed, the pressurizing water pump 8 firstly works, water at the upper part of the steel gate body 2 is pumped and pressurized and then respectively enters the water storage cavity 5 along the pressurizing branch pipe 7, the water storage cavity 5 is enabled to form a high-pressure cavity by high-pressure water, reaction force is formed on the pressurizing support 3 and acts on the steel gate body 2, so that the pressure brought to the steel gate body 2 by upstream water is resisted, the pressure between the track 4 and the pressurizing support 3 is reduced, the sliding friction resistance of the steel gate body 2 when the steel gate body is opened is reduced, and the opening and closing force of the gate is greatly reduced.
Because the upstream water pressure of the gate increases along with the increase of the depth, the upstream water pressure distribution of the steel gate body 2 is more complex when the steel gate body 2 is partially opened, and the pressurizing supports 3 are arranged in a plurality of pairs along the height direction of the steel gate body 2, so that the pressure of each water storage cavity 5 automatically adapts to the upstream water pressure, the balance of the gate body 2 in the operation process is ensured, and the pressurizing supports 3 can be uniformly arranged or not according to the structure selection of the gate body 2; the flow regulating valve 9 is arranged to enable the flow in each pressurizing branch pipe 7 to be equal, and the water storage cavity of each pressurizing support 3 is effectively guaranteed to be capable of forming effective pressure to adapt to the upstream water pressure.
Because the steel gate body 2 can deform under the action of water pressure and the manufacturing precision of the steel gate body 2 and the track 4 is limited, in order to ensure that each water storage cavity 5 can be effectively sealed, an annular clamping plate 10 is fixedly arranged at the edge of an opening of the pressurizing bearing 3, a supporting adjusting block 11 which is attached to the track 4 is arranged on the inner annular surface of the annular clamping plate 10 in a manner of clinging to the inner side of the annular clamping plate (the supporting adjusting block 11 is generally made of copper or engineering plastics, has certain strength, corrosion resistance and toughness and has certain deformation when being subjected to high water pressure), the supporting adjusting block 11 is movably arranged in a clamping groove formed between the annular clamping plate 10 and the pressurizing bearing 3 and moves back and forth in the clamping groove along the width direction of the groove, the moving stroke of the water storage cavity is generally 5-15 mm, and when high-pressure water is conveyed into the water storage cavity 5, the supporting adjusting block 11 can be ejected out, so that the deformation of the steel gate body 2 is adapted; and a water-blocking sealing ring 12 is arranged on the joint surface of the support adjusting block 11 and the bottom of the clamping groove, so that high-pressure water is prevented from flowing out along a gap at the bottom of the clamping groove, and the pressure in the water storage cavity 5 is ensured to be stable.
