Description

Technical Field

[0001] This utility model relates to the field of air-supported membrane building technology, specifically to an air circulation device for air-supported membrane buildings. Background Technology

[0002] Air-supported membrane structures refer to a building structure system that uses special architectural membrane materials as the outer shell and is equipped with a set of intelligent electromechanical equipment to provide positive air pressure inside the air-supported membrane structure to support the main body of the building. Air-supported membrane structure systems provide the fastest and most flexible construction method for large venues, with on-site construction taking no more than a week, which is unmatched by any other building structure. Similarly, it also saves you project management costs. The flexibility of the construction method can meet a variety of customer needs. It has low foundation requirements, is lightweight, can be built on top of existing buildings, and can be moved at any time. Air-supported membrane structures are characterized by large span area and flexibility, and can be customized for large-scale buildings, such as airports, waiting halls, industrial plants, warehouses, etc.

[0003] Existing patent application CN202320980469.0 discloses an air circulation device for an air-supported membrane structure, comprising: a base, a membrane body, a circulation duct, an air inlet pipe, and an air outlet pipe. The base is used to construct the entire air-supported membrane structure and provide support points. The membrane body is fixedly connected to the upper surface of the base. A circulation mechanism is disposed on the inner wall of the membrane body. Through the combined use of the air inlet pipe and the circulation duct, an exhaust fan draws outside air into the circulation duct through the air inlet pipe. The outside air passes through a filter screen, then through an activated carbon adsorption plate, and then into the exhaust duct, thereby achieving a self-cleaning effect. Through the combined use of a motor and the exhaust duct, starting the motor causes a sliding block to move up and down via a reciprocating screw. The sliding block causes a rubber block to move up and down, causing the rubber block to move up and down on the surface of the ventilation plate and ventilation grid, allowing air to be blown out from the ventilation plate or ventilation grid, thereby achieving the effect of adjusting the air pressure.

[0004] The above solution has the following problems during implementation: the filter screen and activated carbon adsorption screen are both slidably connected in the chute by a slider without any limiting structure. This causes the vibration generated when the circulating air box is started to move the slider out of the chute, and the filter screen and activated carbon adsorption screen out of the circulating air box, thus affecting the normal use of the filter screen and activated carbon adsorption screen. Therefore, an air-supported membrane building air circulation device is needed to solve the above problems. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: an air circulation device for an air-supported membrane building, including a circulating air box 1, a filter plate 101, and an activated carbon adsorption plate 102. Slider blocks 103 are fixedly connected to the top and bottom ends of the filter plate 101 and the top and bottom ends of the activated carbon adsorption plate 102, respectively. Side plates 104 are fixedly connected to the side ends of the filter plate 101 and the activated carbon adsorption plate 102, respectively. Each side plate 104 has a slot 105 and an L-shaped groove 106 on its side end. The groove 106 facilitates movement. The operator pulls the filter screen 101 and the activated carbon adsorption screen 102 to avoid the space occupied by long handles. Two sets of limiting components 2 for fixing the filter screen 101 and the activated carbon adsorption screen 102 are symmetrically arranged on the side of the circulating air box 1. By setting the limiting components 2, the filter screen 101 and the activated carbon adsorption screen 102 can be fixed. At this time, the vibration generated when the circulating air box 1 is started can be prevented from causing the filter screen 101 and the activated carbon adsorption screen 102 to move out of the circulating air box 1, thereby avoiding affecting the normal use of the filter screen 101 and the activated carbon adsorption screen 102.

[0021] As one implementation method in this embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the limiting component 2 includes a fixed box 201, which is fixedly connected to the side of the circulating air box 1. An insert plate 202 is inserted from the outer end to the interior of the fixed box 201. The insert plate 202 is adapted to the slot 105. A rectangular plate 203 is fixedly connected to the side of the insert plate 202. A connecting rod 204 is fixedly connected to the side of the rectangular plate 203. The side of the connecting rod 204 is inserted to the outer side of the fixed box 201. A lever 205 is fixedly connected to the side of the connecting rod 204. A spring 206 is fitted at one end, with one end of the spring 206 fixedly connected to the inner side of the fixed box 201 and the other end fixedly connected to the side of the rectangular plate 203. A magnet 207 is fixedly connected to the outer side of the fixed box 201, and a magnet 208 is fixedly connected to the side of the lever 205. Magnets 207 and 208 attract each other. In practice, after the filter screen 101 is inserted into the circulating air box 1, when the side plate 104 passes the position of the insertion plate 202, it is pulled... Motion plate 205 separates magnet 208 from magnet 207. Motion plate 205 then moves connecting rod 204, rectangular plate 203, and insert plate 202. Rectangular plate 203 retracts against spring 206, while insert plate 202 does not obstruct side plate 104, allowing it to continue moving until filter screen 101 is fully inserted into circulating air box 1. At this point, slot 105 on the side of side plate 104 is aligned with insert plate 202. Releasing motion plate 205 then releases spring 206. 6. The rectangular plate 203 rebounds, causing the insert plate 202 to be inserted into the slot 105. At this time, the insert plate 202 can limit and fix the side plate 104 and the filter screen plate 101. Meanwhile, magnet 1 207 and magnet 208 attract each other to fix the position of the lever 205, so that the lever 205 will not easily be displaced due to the vibration when the circulating air box 1 is started. Therefore, in conjunction with the pushing force of the spring 206 on the rectangular plate 203 and the insert rod, the insert plate 202 is more stably inserted into the slot 105.

[0022] Working principle: After the filter screen 101 is inserted into the circulating air box 1, when the side plate 104 passes the position of the insertion plate 202, the lever 205 is pulled to separate the magnet 208 from the magnet 207. At this time, the lever 205 drives the connecting rod 204, the rectangular plate 203 and the insertion plate 202 to move. The rectangular plate 203 compresses the spring 206 and retracts, while the insertion plate 202 does not obstruct the side plate 104. The side plate 104 can continue to move until the filter screen 101 is fully inserted into the circulating air box 1. At this time, the slot 105 on the side end of the side plate 104 is aligned with the position of the insertion plate 202. When the lever 205 is released, the spring 206 pushes the rectangular plate 203 back and drives the insertion plate 202 into the slot 105. 02 can limit and fix the side plate 104 and the filter screen plate 101. At this time, magnet 1 207 and magnet 208 attract each other to fix the position of the lever 205, so that the lever 205 will not easily be displaced by the vibration when the circulating air box 1 is started. Therefore, with the spring 206 pushing the rectangular plate 203 and the insertion rod, the insertion plate 202 is more stably inserted into the slot 105, fixing the filter screen plate 101. The activated carbon adsorption screen plate 102 is fixed in the same way. At this time, the vibration generated when the circulating air box 1 is started can be prevented from causing the filter screen plate 101 and the activated carbon adsorption screen plate 102 to move out of the circulating air box 1, thereby avoiding affecting the normal use of the filter screen plate 101 and the activated carbon adsorption screen plate 102.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
