A new type of flat gate

Abstract

The invention discloses a novel bulkhead gate. The novel bulkhead gate comprises groove rails, a cross beam, a gate leaf, a bottom beam and gate opening sliding blocks; the groove rails are vertically arranged on the two sides of the bottom beam; the groove rails and the cross beam are closed to form a gate leaf frame; the gate leaf is arranged in the gate leaf frame; positioning sliding grooves and damping rubber plates are arranged in the groove rails; fixing grooves are formed in one side of the working surface of the gate leaf; fixes shafts and damping shaft sleeves are arranged in the fixing grooves; sliding grooves are formed in the other side, opposite to the working surface, of the gate leaf; rolling shaft sleeves and the gate opening sliding blocks are arranged in the sliding grooves; the damping shaft sleeves are matched with the damping rubber plates in the positioning sliding grooves in a contact mode; and the rolling shaft sleeves are matched with the gate opening sliding blocks in a rolling mode. According to the novel bulkhead gate, when the gate leaf is lifted, firstly the gate opening sliding blocks are lifted to ascend, the inclined surfaces on the gate opening sliding blocks abut against the rolling shaft sleeves, the bottom of the gate leaf is opened firstly to enable the gate opening sliding blocks to be ejected out of the surface of the gate leaf and to be higher than a water stop belt, at the moment, the gate leaf falls on hook tables in the sliding grooves of the gate opening sliding blocks, and therefore the purposes of releasing pressure and protecting the water stop belt can be achieved, and the opening strength for opening the gate leaf can be reduced.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a novel flat gate with simple structure and convenient use. Background technique [0002] At present, the gates used in the flood and sand discharge holes of reservoir dams are basically flat gates and arc gates. The flat gates have the advantages of simple structure, convenient construction, small investment, and interchangeability. The door force is large, the water stop is easy to be eroded and damaged, the door groove is easy to cavitate in high-speed water flow, and the door leaf vibrates greatly. Therefore, the working gate in the flood discharge and sand discharge hole of the reservoir dam often uses an arc gate, and The structure of the gate is complex, the construction is difficult, the stress points are concentrated, the sealing process of the water stop is complicated, difficult, and the investment is also relatively large. It is an i...

Problems solved by technology

[0005] In the present invention, fixing grooves and slide grooves are arranged on both sides of the door leaf, a groove is arranged on the door opening slider, the inner wall surface of the groove is arranged as an inclined surface, and a hook table is arranged on the inner bottom of the groove. When the door leaf is hoisted, firstly, the Move the door opening slider to rise, and the inclined surface on the door opening slider bears against the rolling bushing. Firstly, the bottom of the door leaf is opened, so that the door opening slider pushes out of the door leaf surface, which is higher than the water stop belt. At this time, the door leaf falls to the bottom of the door leaf. On the hook platform of the door opening slider, the purpose of pressure relief and protection of the waterstop is achieved, and the opening force when starting the door leaf is reduced. At this time, the door leaf can be freely placed in the groove on the hook platform in the groove of the slider Slide up and down in the rail and the positioning chute, the door leaf is set in a tapered boss structure, the bottom beam and the groove edge of the groove rail are also set in a structure with inconsistent height and width, the purpose is to set the entire gate with a small facing water surface, The structure with a wide outlet surface enables the high-pressure water to jump over the gate groove and achieve the purpose of preventing cavitation in the gate groove. The whole device achieves the purpose of pressure relief, protection of the water stop belt, prevention of vibration of the door leaf, and prevention of cavitation of the groove rail. It fundamentally solves the problems of traditional flat gates, such as door slot cavitation, door leaf vibration, hard opening of the door, and easily damaged waterstops.
