Problems solved by technology
[0002] At present, for the down-the-hole inspection gate of the tailwater cooler with the same groove as the tailwater inspection gate, the P-type water seal device is generally used in the prior art. When the height from the normal water level to the installation platform of the tail water cooler is high, the P-type water seal device is easily damaged when the compression deformation is too large due to the high water head of the tail water cooler submersible maintenance gate. When using the above, its water-stopping effect is very poor
Therefore, there are still deficiencies in the existing technology, which cannot meet the needs of use, and need to be further improved.

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] The water sealing method of the submerged-hole overhaul gate of the tail water cooler of the present invention is to pre-set a water-stop seat plate arranged in a rectangular shape on the side of the water inlet and outlet holes, and set the submerged-hole overhaul gate of the tail water cooler on the unit A rectangular frame is set on the gate panel on the side, and a pressurized Ω water seal device is installed on the rectangular frame. At the same time, a connecting pipe is set on the tail water cooler submersible inspection gate so that the inner cavity of the pressurized Ω water seal device can communicate with the external water body; in this way, the tail water cooler submersible inspection gate is closed and fully After the pressurized Ω water seal device is in contact with the water stop plate, the external water body is presse...

The invention discloses a water sealing method and device for a tail water cooler down-the-hole bulkhead gate. The water sealing method comprises the steps that a water stopping seat plate arranged ina rectangular shape is arranged on the side face of a water inlet-outlet hole, a rectangular frame is arranged on a gate face plate of the tail water cooler down-the-hole bulkhead gate, meanwhile, apressurized omega water-sealing device body is arranged on the rectangular frame, and meanwhile, a communicating pipe capable of enabling an inner cavity of the pressurized omega water-sealing devicebody to communicate with an external water body is arranged on the tail water cooler down-the-hole bulkhead gate; and in this way, the external water body can be pressed into the inner cavity of the pressurized omega water-sealing device body through the communicating pope, thus the water body applies the pressure to a water sealing head of the pressurized omega water-sealing device body from theinterior, and the water stopping effect of the tail water cooler down-the-hole bulkhead gate is effectively improved. The water sealing method and device have the advantages of simple structure and reliable working performance, and meanwhile have the advantages of being not prone to being damaged when bearing the high water head, and good in water stopping effect, long in service life and the like.
Description
technical field [0001] The invention relates to a water sealing method and device for a down-hole inspection gate of a tail water cooler, and belongs to the technical field of water sealing for a down-hole inspection gate of a tail water cooler in a water conservancy and hydropower project. Background technique [0002] At present, for the down-the-hole inspection gate of the tailwater cooler with the same groove as the tailwater inspection gate, the P-type water seal device is generally used in the prior art. When the height from the normal water level to the installation platform of the tail water cooler is high, the P-type water seal device is easily damaged when the compression deformation is too large due to the high water head of the tail water cooler submersible maintenance gate. When using above, its water-stopping effect is very poor. Therefore, there are still deficiencies in the prior art, which cannot meet the needs of use, and need to be further improved. Con...
