Improving method and device for two-way plane gate water sealing device

Abstract

The invention discloses an improving method and device for a two-way plane gate water sealing device, and aims at improving an existing straight-line double-P-type water seal into an L-shaped double-P-type water seal and installing the L-shaped double-P-type water seal at an outer corner of a gate groove. A vertical water flow P type head of the L-shaped double-P-type water seal stretches into a gap formed between the gate groove and a gate flap and corresponds to a vertical water flow water seal base plate installed on a vertical water flow plane of the gate groove; and a downstream water flow P type head of the L-shaped double-P-type water seal corresponds to a downstream water flow water seal base plate installed on a downstream water flow plane of the gate groove. According to the improving method and device, compressive deformation of the water seal of the gate water sealing device always can not exceed a normal valve on the condition that the water flow direction is changed, and then the life of the water seal is effectively prolonged; meanwhile, the size of the gate groove can be effectively decreased, therefore, the hydraulic conditions of the gate groove are good, and the gate running safety is effectively guaranteed.

Description

technical field [0001] The invention relates to an improvement method and device of a water-stop device for a bidirectional plane gate, belonging to the technical field of water conservancy and hydropower engineering. Background technique [0002] For the working gates of barrages and dams near the sea estuary or retreating sluices in lake storage (line) flood areas, the working gates have two-way water retaining and operation requirements. type, and the two-way water retaining gate is usually supported by a fixed wheel on one side, and a high-strength slideway on the other side. According to the direction of water flow, the fixed wheel and the high-strength slideway are mutually positive and negative support limits. When the fixed wheel is the main support, a gap of about 4-5mm is reserved between the high-strength slideway and the track for the reverse support, and the water seal head and the water seal seat plate are pre-compressed by 4-5mm to stop the water. When the ...

Problems solved by technology

When the fixed wheel is the main support, a gap of about 4-5mm is reserved between the high-strength slideway and the track for the reverse support, and the water seal head and the water seal seat plate are pre-compressed by 4-5mm to stop the water. When the fixed wheel is the reverse support, The high-strength slideway of the main support is in contact with the track. Because the contact parts of the two water seal heads and the water seal seat plate of the traditional double-headed P-type water seal are on the same plane, the contact pre-compression of the water seal head and the water seal seat plate reaches 8-10mm, the water seal will be damaged due to long-term excessive compression; in addition, the size of the traditional double-headed P-type water seal in the door slot is large, which will increase the width of the door slot, and the hydraulic conditions are poor. Therefore existing technology is not ideal enough yet, needs to be perfected further
