Improved method and device of top water seal on submerged-hole radial gate

Abstract

The invention discloses an improved method and a device of a top water seal on a submerged-hole radial gate. The top water seal on the submerged-hole radial gate is composed of a double-round-head water seal device arranged on a door lintel base and a cover pressing type P-type water seal device at the top of a gate, a reservoir water communicating and operating hole is formed in the lower part ofthe door lintel base, so that the double-round-head water seal device is convenient to assemble; communicating holes are formed in the part, on the downstream side of the door lintel base, of the rear part of the double-round-head water seal device communicates with the reservoir water; under the condition that a compression amount of the double-round-head water seal is not large, a water seal head is enabled to be stretched to be in tight contact with a panel of the submerged-hole radial gate through a water pressure of a reservoir area, a compression amount is not increased, the water sealhead which is in contact with the panel of the submerged-hole radial gate is additionally arranged in the double-round-head water seal compared with a traditional omega water seal, the water seal device is additionally arranged in a equivalent mode, and a water stop effect of the water seal is enhanced while the compression amount of the water seal is not increased; and the cover pressing type P-type water seal device at the top of the submerged-hole radial gate is in perpendicular contact with the door lintel base, and is not in contact with a water seal base plate in an operation process ofthe submerged-hole radial gate, and the service life of the water seal is effectively guaranteed while the water stop effect of the water seal is enhanced.

Description

technical field [0001] The invention relates to an improved method and device for a water seal at the top of a submerged-hole arc door, belonging to the technical field of metal structures of water conservancy and hydropower projects. Background technique [0002] For the water seal device on the top of the submerged hole arc door, there are mainly three types: the pressure-charged telescopic type, the eccentric hinge compression type and the conventional pre-compression type. For submersible arc doors, the conventional preloading type is mostly used for medium and high head submersible arc doors. Generally, a P-type water seal is installed on the top of the submersible arc door, and an Ω water seal is installed on the lintel. The P-type water seal and the Ω water seal are both The pre-compression type mainly relies on the amount of compression to stop the water, but there are differences in the level of on-site installation technology, which may cause the compression amount...

[0002] For the water seal device on the top of the submerged hole arc door, there are mainly three types: the pressure-charged telescopic type, the eccentric hinge compression type and the conventional pre-compression type. For submersible arc doors, the conventional preloading type is mostly used for medium and high head submersible arc doors. Generally, a P-type water seal is installed on the top of the submersible arc door, and an Ω water seal is installed on the lintel. The P-type water seal and the Ω water seal are both The pre-compression type mainly relies on the amount of compression to stop the water, but there are differences in the level of on-site installation technology, which may cause the compression amount of the P-type water seal and the Ω water seal of the gate to be too large or too small, which will increase the wear of the water seal , if it is too small, it will not be able to seal the water. Therefore, there are still deficiencies in the existing technology and need to be further improved.
