Description

Technical Field

[0001] The utility model relates to the technical field of air circulation, in particular to an air circulation device for air-supported buildings. Background Technique

[0002] The air-supported building relies on the internal and external air pressure difference to support the whole building. Due to the flexibility of the material, the inherent effectiveness of the structure and the arc-shaped body shape, there are no components subjected to bending, torsion and compression. There is no need for any internal frame or beam column support, and the span can reach 110 meters. As the atmospheric pressure increases, the environmental oxygen content increases. Therefore, the air pressure difference inside and outside the air-supported building will not have any adverse effects on the human body, but will help people engage in sports activities or physical work.

[0003] The air inside the air-supported building needs to be circulated. If there is a lack of effective air circulation, the air quality will decline, the carbon dioxide concentration will rise, causing symptoms such as dyspnea and dizziness, and posing health hazards. At the same time, the humidity in the air will also increase, which may lead to the growth of mold and bacteria, further affecting the health of the indoor personnel.

[0004] The air circulation devices of traditional buildings often install ventilation fans on the walls or ceilings, but air-supported buildings are not suitable for ventilation fans because the structural characteristics and materials of air-supported buildings limit the installation and operation of traditional ventilation equipment. Air-supported buildings mainly rely on inflation to maintain their shape and use flexible membrane materials, which cannot provide enough support and fixing points to install heavy ventilation equipment. In addition, air-supported buildings are usually temporary or movable, and their flexibility and convenience are not suitable for traditional fixed ventilation devices. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that it is not convenient to install traditional ventilation equipment for air circulation in air-supported buildings.

[0006] To solve the above technical problem, the technical solution adopted by the utility model is: an air circulation device for air-supported buildings, including a substrate, a pillar sleeve is fixedly connected to the top of the substrate, slots are opened on both sides of the pillar sleeve, a pillar is slidably connected in the pillar sleeve, a limiting component is arranged on one side of the pillar, a ventilation chamber is fixedly connected to the top of the pillar, a separation cover is fixedly connected to the top of the ventilation chamber by bolts, a filter element is clamped in the ventilation chamber through a cross-shaped card slot, ventilation fans fixedly connected to the ventilation chamber are arranged on both sides of the filter element, and filter discs are arranged at both ends of the ventilation chamber and the separation cover.

[0007] As a further improvement of the present utility model, the limiting component includes a telescopic rod fixed on one side of the pillar. One end of the telescopic rod passes through the slotted opening and is fixedly connected with a fastener. One side of the pillar sleeve is fixedly connected with a fastening seat, and the fastening seat is provided with a plurality of fastening grooves for the fastener to be clamped.

[0008] As a further improvement of the present utility model, a pillar handle is fixedly connected to one side of the pillar, and the pillar handle is located in the slotted opening on the side away from the limiting component.

[0009] As a further improvement of the present utility model, four movable casters are fixedly connected to the bottom end of the base plate, and all four movable casters are provided with locking structures.

[0010] As a further improvement of the present utility model, sliders are fixedly connected to both ends of the two filter discs, and the ventilation chamber and the separation cover are both provided with sliding grooves for the sliders to slide.

[0011] As a further improvement of the present utility model, grips are fixedly connected to both sides of the two filter discs.

[0012] The beneficial effects of the present utility model: The present utility model has the advantages of being movable and adjustable. Since the materials of the air film building do not have enough support points and fixed points to install heavy ventilation equipment, by means of the pre-opened ventilation openings in the air film building, through the pillars, pillar sleeves and limiting components with adjustable distances, according to the actual situation, the ventilation openings at different heights and positions are connected to filter and circulate the air in the air film building. At the same time, movable casters are provided, which facilitate the user to transport and displace the air circulation device. The operation is convenient and stable, and the flexibility and applicability are good. At the same time, the subsequent cleaning work for the filter element and the filter disc is convenient and simple. Description of the Drawings

[0021] The present utility model provides an air circulation device for an air film building as shown in the attached Figures 1 - 4 figure. The air circulation device includes a substrate 1. A support sleeve 2 is fixedly connected to the top of the substrate 1. Slots are provided on both sides of the support sleeve 2. A support 3 is slidably connected in the support sleeve 2. A limit assembly 4 is provided on one side of the support 3. The top of the support 3 is fixedly connected to a ventilation chamber 5. A separation cover 6 is fixedly connected to the top of the ventilation chamber 5 by bolts. A filter element 8 is clamped in the ventilation chamber 5 through a cross-shaped card slot 7. Ventilation fans 9 fixedly connected to the ventilation chamber 5 are provided on both sides of the filter element 8. Filter discs 10 are provided at both ends of the ventilation chamber 5 and the separation cover 6.

[0022] As Figure 1 , 2As shown, the limit component 4 includes a telescopic rod 401 fixed to one side of the support column 3. The telescopic rod 401 passes through one end of the slotted opening and is fixedly connected to a fastener 402. One side of the support column sleeve 2 is fixedly connected to a fastening seat 403, and the fastening seat 403 is provided with a plurality of fastening grooves for the fastener 402 to be snap-fitted. The provided limit component 4 is used to fix and adjust the height of the support column 3, suitable for ventilation requirements in different situations. One side of the support column 3 is fixedly connected to a support column handle 11, and the support column handle 11 is located in the slotted opening on the side away from the limit component 4.
