A water pressure relief apparatus in a traveling water screen adapted to be mounted in a channel such that the traveling water screen filters water flowing through the channel. The channel includes an upstream portion and a downstream portion. The traveling water screen includes a baffle directing water flowing through the traveling water screen and having an upstream surface communicating with the upstream portion of the channel and a downstream surface communicating with the downstream portion of the channel. The baffle has an opening connecting the upstream surface to the downstream surface. The water pressure relief apparatus includes a relief valve adapted to be connected to the baffle. The relief valve has a valve member mounted for movement between an opened position allowing fluid flow through the opening and a closed position engaging the valve seat and sealing the opening against flow therethrough.

Differential relief mechanism for a traveling water screen

An apparatus for securing a traveling water screen in a channel, the channel having a sidewall and a vertically extending groove in the sidewall. The traveling water screen includes a frame positioned in the channel, a plurality of water screens supported by the frame for screening water flowing through the channel, and a support structure connected to the traveling water screen to position the traveling water screen in the channel. The support structure includes a guide member extending into the sidewall groove. The apparatus includes a guide lock fixed to the sidewall of the channel. The guide lock engages the guide member to hold the guide member in the vertically extending groove in the channel sidewall and thereby secure the traveling water screen in the channel.
