Convenient-to-overhaul tail water cooler device

Abstract

The invention discloses a convenient-to-overhaul tail water cooler device. The device comprises a group of gate hanging holes, an upper platform is arranged on the chest wall top surface on the gate hanging hole unit side, and a tail water cooler is arranged on the upper platform; a water retaining chest wall is arranged above the upper platform, a rectangular down hole is formed between the waterretaining chest wall and the upper platform, and a tail water cooler overhauling gate is arranged at the rectangle down hole; an H-shaped water seal supporting assembly is arranged on the gate hanging hole gate groove side; and the surface of a panel of the tail water cooler overhauling gate is provided with a rectangular water seal assembly with the periphery water stop function; and the rectangular water seal assembly is in water stop connection with the H-shaped water seal supporting assembly. According to the convenient-to-overhaul tail water cooler device, when the tail water cooler needs to be overhauled, underwater operation of a diver is not required, and the tail water cooler does not need to be lifted out of the platform during overhauling, so that overhauling and maintenance are very convenient, the overhauling efficiency is greatly improved, and the personal safety of overhaul personnel is greatly guaranteed.

Description

technical field [0001] The invention relates to a device for convenient maintenance of a tail water cooler, which belongs to the technical field of metal structures of water conservancy and hydropower projects. Background technique [0002] For hydropower projects with large sediment content and many impurities, the tail water cooler usually adopts the circulation cooling water supply method, and the tail water cooler is installed on the upper platform of the tail water outlet inspection gate. Considering that the cooling effect will not be affected, the tail water cooler is set as a whole In the lower part of the normal tail water level, the existing technology uses divers to install and remove the tail water cooler; the specific method is as follows: during maintenance, divers are used to dive to the installation support of the cooler, and after removing the connecting bolts, lift out the tail water cooler for maintenance. After the overhaul is completed, put the tail wate...

Problems solved by technology

[0002] For hydropower projects with large sediment content and many impurities, the tail water cooler usually adopts the circulating cooling water supply method, and the tail water cooler is installed on the upper platform of the tail water outlet inspection gate. Considering that the cooling effect will not be affected, the tail water cooler is set as a whole At the lower part of the normal tail water level, the existing technology uses divers to install and remove the tail water cooler; the specific method is as follows: during maintenance, divers are used to dive to the installation support of the cooler, and after removing the connecting bolts, lift out the tail water cooler for maintenance. After the overhaul is completed, put the tail water cooler, and then send divers to dive to the installation support of the cooler to connect and fix it. It is very troublesome to ask divers every time during the maintenance, and it is even more inconvenient for remote places. The tail water cooler The accuracy of underwater alignment installation and removal is poor, and the underwater operation is difficult and dangerous, especially for hydropower projects where the normal tail water level is higher than the upper platform of the tail water outlet maintenance gate. Therefore, the existing technology There are still deficiencies that need to be further improved
