Problems solved by technology

Due to the large number of windshields, large volume and heavy weight, the annual manual suspension and removal of windshields requires a lot of work, which is not only labor-intensive and takes up a lot of time, but also manual high-altitude operation is not safe. At the same time, windshields It is easy to be damaged in the process of frequent fixing and removal, the maintenance cost is high, and the use effect

Abstract

The invention discloses an automatic starting and closing type anti-freezing device of a wind screen of a cooling tower, comprising an air partition ceiling, an adjustable wind-shield wall and a cooling tower body, wherein the air partition ceiling is fixed on the cooling tower body and the adjustable wind-shield wall; the adjustable wind-shield wall comprises a plurality of synchronous rotation starting and closing units of the wind screen, and each synchronous rotation starting and closing unit of the wind screen comprises a frame, a wind screen, an upper rotating component, a lower rotating component and a synchronous driving part; the wind screen can rotate relatively to the frame, and all wind screens are driven to synchronously rotate by the synchronous driving part. Because the wind screen is installed on the frame in the rotating mode, the wind screen can rotate relatively to the frame; when temperature is low in winter, the synchronous driving part drives all wind screens to be in closing state, and all wind screens are in the starting and ventilating state when the temperature rises. The invention can freely adjust the starting and the closing state of the wind screens according to external temperature so as to ensure that the cooling tower can normally and efficiently operate in any season.

Description

【Technical field】 [0001] The invention relates to a windshield and antifreeze device for a cooling tower of a power plant. 【Background technique】 [0002] In the severe cold regions of the north, anti-icing facilities must be installed for hyperbolic natural ventilation cooling towers, otherwise, the cooling tower will cause serious ice-hanging phenomenon, resulting in water-splashing fillers, brackets falling and part of the water-spraying structural beams in the cooling tower Severe freezing and thawing of the exposed ribs caused by the column makes the cooling tower unable to operate normally and safely, let alone effectively control the water temperature in the cooling tower. For a long time, people have usually adopted the method of building a windshield around the cooling tower to solve the antifreeze problem. The windshield is composed of a frame and a windshield, and the windshield is hung on the frame by artificial suspension. When winter comes, it is necessary to ...
