Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in fig. 1 and 2, the air film top exhaust device comprises an air film building 1 and a bladeless air ball 2, wherein a vent 3 is arranged at the top of the air film building 1, an annular lower fixing plate 4 is arranged inside the vent 3, an annular upper fixing plate 5 is arranged on the upper portion of the vent 3, the annular lower fixing plate 4 and the annular upper fixing plate 5 are fixed through a plurality of connecting bolts 6, a connecting cylinder 7 is installed on the annular upper fixing plate 5, and the bladeless air ball 2 is installed on the connecting cylinder 7.
Wherein, the vent 3 is provided with a first support ring 8, a second support ring 9 and a third support ring 10, the first support ring 8 and the second support ring 9 are arranged above the vent 3, the third support ring 10 is arranged below the vent 3, the diameters of the first support ring 8 and the third support ring 10 are the same, after the upper membrane of the air film building 1 bypasses the first support ring 8 and the second support ring 9, folded in a position between the first support ring 8 and the second support ring 9, the annular upper fixing plate 5 is arranged between the first support ring 8 and the second support ring 9, and presses the upper membrane, the lower membrane of the air film building 1 winds around the third support ring 10 and then is folded at the bottom of the lower membrane, the annular lower fixing plate 4 is sleeved outside the third support ring 10, and presses on the lower layer membrane, and the annular lower fixing plate 4 and the annular upper fixing plate 5 are connected through a connecting bolt 6.
According to the utility model, the vent is arranged at the top of the air film building, the inner side and the outer side of the vent are respectively wound through the first support ring 8, the second support ring 9 and the third support ring 10, and the air film discharged from the vent is wound, so that the annular lower fixing plate 4 and the annular upper fixing plate 5 can press the air film, the support strength of the vent is increased, the sealing performance of the air film discharged from the vent can be ensured, and air leakage is avoided. The annular upper fixing plate 5 is provided with a connecting cylinder, the inner diameter of the connecting cylinder is the same as the diameter of the inner ring of the annular upper fixing plate, and the connecting cylinder is welded on the annular upper fixing plate. The bladeless wind ball is fixed on the connecting cylinder through a bolt to complete the fixation. The top of the air film building is provided with the bladeless fan ball, the bladeless fan ball can form automatic rotation power in the form of internal and external pressure difference, and automatically rotate to form a siphon effect, so that heat is quickly discharged; meanwhile, when air is exhausted through the wind ball, the wind flow has outward jacking pressure on the wind ball, and the wind ball is more favorable for the air-supported membrane structure.
In addition, the annular lower fixing plate 4, the annular upper fixing plate 5 and the connecting cylinder 7 are made of aluminum materials, and can also be made of stainless steel materials. Because the membrane material is mainly supported through the internal and external pressure difference, the material of the ventilation duct cannot be too heavy, and therefore, the fixing point can be provided for the unpowered wind ball while the hole is formed in the membrane material.
The present invention is not limited to the above preferred embodiments, but rather, any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
