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 of water conservancy and hydropower projects, in particular to an improved method and structure of an extra-high water head plane sliding gate. Background technique

[0002] For plane sliding gates with extra-high water head, a water stop is usually arranged downstream, and two rows of sliders are arranged on both sides of the downstream forward direction as the main support type. This has the disadvantage that the positive and negative positions of the gate are only limited by the left and right sides, and the gate is prone to accidents during the opening process. vibration, while the upstream panel of the plane sliding gate or the rear flange of the bottom main beam is generally a broken line mutation structure, which will cause the flow state of the water flow to be disordered and increase the force of the water flow on the gate, so it is also easy to induce gate vibration and increase ...

Examples

Embodiment Construction

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

[0033] look first figure 1 , figure 1 A schematic diagram of the layout of the present invention is shown, from figure 1 As can be seen in the figure, the present invention arranges an extra-high water head plane sliding gate 2 in the door slot 1. Door slot 1 is provided with upstream high parapet 7 and downstream high parapet 8; more detailed structures, such as Figure 2-3 As mentioned above, it can be seen from the figure that reverse supports 3 are provided on both sides and top of the facing surface of the extra-high water head plane sliding gate 2, forward supports 4 are provided on both sides and top of the back surface, and lateral supports 5 are provided on the sides; The slot 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, ...
