Technical Field

The invention relates to the field of weir gate sealing rubber water-stopping and seepage-proofing sealing, in particular to a novel weir gate sealing structure.

Background

In the prior art, the weir gate is generally sealed by adopting a P-shaped water stop rubber strip, and in order to ensure the water stop effect, a pre-compression 2mm installation method is adopted during the installation of the water stop belt according to the standard requirement. Therefore, although the water stopping effect is not good, the friction force for opening and closing the weir gate is increased, and the abrasion to the rubber water stopping belt is correspondingly increased. In fact, the installation and construction difficulty is correspondingly increased, the uniformity of the pre-compression amount is difficult to ensure, therefore, the phenomenon of local water leakage of the weir gate sealing water is frequent, the more prominent problem is that in the freezing season of cold regions, the gate section can generate the more obvious cold contraction phenomenon, the shrinkage deformation of the weir gate sealing gate blade is also obvious, at the moment, the pre-compression amount of the rubber water sealing is difficult to compensate the superposition amount of the gate section and the weir gate shrinkage, and therefore the phenomenon that the weir gate water leakage is more serious than summer in the freezing season is caused.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a novel weir gate sealing structure, an inflatable or water cavity is formed in an omega-shaped water-stopping rubber strip, namely when the omega-shaped water-stopping rubber strip is installed, the inflatable or water cavity is formed, the sealing effect of the omega-shaped water-stopping rubber strip and a water-stopping surface can be realized through the inflation or water pressure control, and the novel weir gate sealing structure has the advantages of simple and convenient field construction operation, simple composition, good sealing effect, economy, environmental protection and greatly less engineering maintenance cost.

In order to solve the technical problems, the invention provides the following technical scheme:

the invention discloses a novel weir gate sealing structure which comprises a weir gate, an omega-shaped water stop rubber strip, a water stop rubber strip seat plate, a weir gate door frame and a positioning device, wherein the positioning device comprises two fixing blocks and a connecting rod with an opposite T-shaped structure, the two fixing blocks are arranged on the inner side of the end part of the weir gate door frame in parallel, the end parts of the two fixing blocks are connected through the connecting rod, the weir gate is arranged inside the weir gate door frame, and the end part of the weir gate, facing the positioning device direction of the inner side of the weir gate door frame, is provided with the omega-shaped water stop rubber strip.
