Abstract

The invention discloses a novel antifreezing and deicing device for a spillway gate. The device comprises a controller, an icing detector, immersible pumps, automatic check valves, connecting water pipes, a water spray pipe, buoyancy units and span wire fixing units. The icing detector is arranged on the surface of a snorkeling unit water area, and the immersible pumps are arranged under the water surface of the snorkeling unit water area. The immersible pumps and the icing detector are connected with the controller. The controller reads current state information. The connecting water pipes are connected between the immersible pumps and the water spray pipe and connect the immersible pumps and the water spray pipe. The water spray pipe adopts water extracted by the immersible pumps to stir a water body. The water spray pipe is connected with the buoyancy units, so that the water spray pipe floats on the water surface all the time along with variation of the water level. The water spray pipe and the buoyancy units are fixed in a set zone through the span wire fixing units.

Description

technical field [0001] The invention relates to the field of hydropower stations, in particular to a novel antifreeze and deicing device for a spillway gate. Background technique [0002] In recent years, my country's hydropower station construction has made great achievements. However, in the construction of hydropower stations, antifreezing and deicing of spillway gates is one of the key points in the design of hydropower stations in alpine regions. The freezing problem of spillway gates in winter in alpine regions seriously affects the normal operation of water conservancy projects. During the freezing period in alpine regions, the thickness of the ice layer in front of the flood gate can reach 1-2 meters. The expansion pressure generated by the ice layer in winter and the shear force when the water level changes will cause stress damage to the gate. In extreme cases, it is easy to damage the gate and Piers are permanently damaged. At present, hydropower stations in alp...
