Anti-freezing device for forebay sand-washing gate of small hydropower station
The anti-freezing device comprises an upstream side anti-freezing mechanism and a downstream side anti-freezing mechanism, the upstream side anti-freezing mechanism comprises a first heat preservation plate and a water spraying assembly, the first heat preservation plate is fixedly installed on the upstream side of a gate pier, and the water spraying assembly is fixedly installed on the downstream side of the gate pier; a first heat preservation cavity is defined between the first heat preservation plate and the breast wall, the upstream side of the gate is located in the first heat preservation cavity, and the water spraying assembly is used for spraying water to the gate; the downstream side anti-freezing mechanism comprises a second heat preservation plate, the second heat preservation plate is fixedly installed on the downstream side of the gate pier, a second heat preservation cavity is defined by the second heat preservation plate and the breast wall, and the downstream side of the gate is located in the second heat preservation cavity. The anti-freezing device has the beneficial effect that the problem that the front part and the rear part of the gate are easy to freeze during the operation of the sand-washing gate of the hydropower station in winter is effectively solved.
本发明公开了一种小型水电站前池冲砂闸防冻装置，其包括上游侧防冻机构及下游侧防冻机构，所述上游侧防冻机构包括第一保温板及喷水组件，所述第一保温板固定安装于所述闸墩的上游侧，所述第一保温板与所述胸墙之间围成第一保温腔，所述闸门的上游侧位于所述第一保温腔内，所述喷水组件用于向所述闸门进行喷水；所述下游侧防冻机构包括第二保温板，所述第二保温板固定安装于所述闸墩的下游侧，所述第二保温板与所述胸墙之间围成第二保温腔，所述闸门的下游侧位于所述第二保温腔内。本发明的有益效果是：有效的解决了水电站冲砂闸在冬季运行中，闸门前、后容易受冻结冰的问题。
