A kind of intelligent blower raising and lowering flag device

Abstract

The invention particularly provides an intelligent blowing flag raising and lowering device. The intelligent blowing flag raising and lowering device comprises a flagpole, a flag surface fixing plate, a raising and lowering mechanism and a blowing mechanism. The flagpole is of a hollow structure; the flag surface fixing plate is connected to the flagpole in a sliding manner through the raising and lowering mechanism; and the blowing mechanism is arranged on the lower portion of the flagpole. A plurality of air doors which are symmetrically and longitudinally arranged at equal intervals are arranged on the flagpole and are placed on the side where the flagpole is in contact with the flag surface fixing plate; each air door is composed of a door frame and a hinge air door body; the hinge air door bodies are movably connected to the door frames; multiple opening air doors are arranged on the two sides of the flag surface fixing plate, and the distance between every two adjacent opening air doors is consistent with the distance between every two adjacent air doors; and an air door jacking ring is fixed to one side, close to each flagpole air door, of the corresponding opening air door. According to the intelligent blowing flag raising and lowering device, through artificial wind generation, in the raising and lowering process of the flag surface, or after the flag surface is fixed, the flag surface can constantly keep in the slowly-waving state even if the flag surface is in the state without natural wind. Meanwhile, a flag does not need to be manually pulled up, and the intelligent blowing flag raising and lowering device can intelligently control the raising and lowering speed of the flag and control whether the flag is constantly waved or not.

Description

technical field [0001] The invention relates to an intelligent wind blowing flag raising and lowering device, in particular to a device which can make the flag face flutter forever during the lifting or fixing period. Background technique [0002] At present, if the wind is not strong or the direction of the wind is wrong, the flag will not flutter with the wind in many occasions, and the purpose of flag raising and fluttering will be lost, which will cause regret for people! The existing blowing flagpoles have certain defects, such as the blowing flagpole provided in the patent announcement number 201943418U, the air outlet on the flagpole is an open structure, and all the air outlets are air, which will cause part of the wind to not blow the flag. Waste; Another example is the air supply flagpole provided in the patent notification number 102758557A, the flagpole is provided with a plurality of window control switch windows, through the opening and closing of the control w...
