Overhead shutter opening and closing device

Abstract

The invention discloses an overhead type shutter opening and closing device. A plurality of window sheets are arranged in a window frame through a rotating shaft. Water leading grooves are formed in the inner side of the window frame. Each window sheet comprises a sealing plate internally provided with a shaft sleeve, vanes and water guiding grooves, wherein the vanes and the water guiding grooves are formed in the two sides of the sealing plate. The vanes of the window sheets and the water guiding grooves are in longitudinal end-to-end lap joint in the window frame. The two ends of the water guiding grooves are transversely connected with the water leading grooves correspondingly. Through the synergistic effect of the obliquely-arranged window vanes, flow guiding sheets, flow guiding grooves, flow leading grooves and the like, rainwater is prevented from entering a room. Each sealing plate internally provided with the correspondingly shaft sleeve is of a double layer structure, and the safe quality problems that corrosion falling, rotating clamping stagnation and the like generated from excessive wearing of fan blades caused by the fact that fan blades rotate frequently, and the rotating shaft is worn are solved. The overhead type shutter opening and closing device is simple in structure, convenient to use and low in manufacture and maintenance cost, the overhead type shutter opening and closing device is applied to an air exhausting opening of a cooling fan at the top of a train, a generator vehicle cooling device is optimized, the durability is high, rain, snow, wind and sand are prevented from entering a cooling room, the generator vehicle operational safety performance is improved, and the high and wide practicability is achieved.

Description

technical field [0001] The invention relates to a louver device, in particular to a top-mounted louver opening and closing device. Background technique [0002] Generator car is a very important type of railway passenger car in my country. In order to meet the electricity demand of trains, generator car needs to run continuously under various weather conditions (including bad weather such as rain and snow). [0003] The diesel engine cooling device is placed in the cooling chamber of the generator car, and the top of the cooling chamber needs to be equipped with a vent. Most of the air exhaust outlets of the existing electric cars are open, or the strip type is open, or the chimney is open. demand, but it cannot prevent the intrusion of wind, rain, snow, etc., and it is inconvenient to use. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a top-mounted louver opening and closing devi...
