Problems solved by technology

[0003] The purpose of the present invention is to provide an improved method and structure of an extra-high water head plane sliding gate, so as to solve the problem that the existing gates of this type are easy to induce gate vibration, it is difficult to close the gate when moving water, and the top of the gate will be damaged under the action of ultra-high water head. Technical problems such as large deviation to the downstream side

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] first look figure 1 , figure 1 A schematic diagram of the arrangement of the present invention is shown, from figure 1 It can be seen in the present invention that a super-high water head plane sliding gate 2 is arranged in the door slot 1 . Door slot 1 is provided with upstream high breast wall 7 and downstream high breast wall 8; more detailed structures, such as Figure 2-3 As can be seen from the figure, reverse supports 3 are provided on both sides and the top of the water-facing surface of the ultra-high head plane sliding gate 2, positive supports 4 are provided on both sides and the top of the backwater surface, and lateral supports 5 are provided on the sides; The groove 1 is provided with rails 6 corresponding to the positive and negative lateral support positions.

[0034] Figure 4 is the upstream view of the invention,...

Abstract

The invention discloses an improved method and structure for an extra-high water head planar slide gate. Reverse supports (3) are arranged on the two sides and the top of a water attaining surface of the planar slide gate (2) correspondingly. Front supports (4) are arranged on the two sides and the top of a water back surface correspondingly. A door groove (1) is provided with rails corresponding to the front supports (4) and the reverse supports (3) in position, and high breast walls (7 and 8) are arranged on the up stream and the down stream correspondingly. The upper portion of a gate bottom edge upstream face (29) is chamfered, the upper portion of a gate bottom edge downstream face (31) is chamfered, and arc (34) transition is adopted at the rear edge of a bottom water seal press plate (33) below a lower transverse plate. Slideways are adopted for supporting pressure on the two sides and the top of a gate main support. A pass of P-shaped water seal (9) and a pass of pressurizing horizontal-E-shaped water seal (10) are arranged on the down stream of the gate front inside to outside. Gate leaf sections are connected through bolts (13). According to the improved method and structure for the extra-high water head planar slide gate, the technical problems that similar gates are prone to gate vibration, dynamic water gate closing is high in difficulty, and the tops of the gates are prone to large displacement towards the down stream side, so that water seals are compressed and deformed greatly, and damage is caused can be solved.

Description

technical field [0001] The invention relates to the technical field of metal structures in water conservancy and hydropower engineering, in particular to an improved method and structure for a plane sliding gate with extra high water head. Background technique [0002] For ultra-high water head plane sliding gates, a water stop is usually installed downstream, and two rows of slider main support types are arranged on both sides of the downstream forward direction. This means that only the left and right sides of the gate are limited in the forward and reverse directions, and the gate is easily generated during the process of lowering the gate. Vibration, while the upstream panel of the plane sliding gate or the rear flange of the bottom main girder is generally a broken-line sudden change structure, which will lead to the disorder of the water flow and increase the force of the water flow on the gate. In addition, the top of the gate is unsupported as a long cantilever conti...
