Description

Technical Field

[0001] This utility model relates to the field of ventilation duct sealing technology, and in particular to a sealing structure for a square warehouse ventilation duct. Background Technology

[0002] In grain and material storage, flat warehouses serve as crucial storage facilities, and the sealing performance of their ventilation systems directly impacts the stability and safety of the storage environment. During ventilation operations, the ventilation duct doors of a flat warehouse must be kept open to ensure unobstructed flow. However, during sealed storage, the doors must be closed, and the ventilation ducts strictly sealed to prevent the intrusion of outside air, moisture, dust, and pests, thus avoiding moisture damage, spoilage, or contamination of stored materials. Therefore, the reliability and durability of the ventilation duct sealing structure are key technical indicators in the design and use of flat warehouses.

[0003] 1. During long-term use, the sealing structure will experience irreversible elastic decay under long-term compression, and its elastic recovery ability will be gradually lost, resulting in an increase in the sealing gap and a significant decrease in the sealing effect.

[0004] 2. When the sealing structure deteriorates or local leakage occurs, it is difficult for staff to detect it in real time. They often need to detect abnormalities in the warehouse environment (such as increased humidity or mold growth on materials) to determine that the seal has failed. By then, storage losses have already occurred.

[0005] Therefore, it is necessary to invent a sealing structure for the ventilation duct of a square warehouse to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a sealing structure for a square-shaped ventilation duct, in order to solve the problem mentioned in the background art that the sealing structure will undergo irreversible creep and aging under long-term compression during long-term use, and its elastic recovery ability will gradually be lost, resulting in an increase in sealing gap and a significant decrease in sealing effect.

[0011] Optionally, the energy storage component includes: Compression springs, which are installed inside the ventilation frame, are used to apply compressive force to the airbag; The pad is mounted on the compression spring and contacts the airbag.

[0012] Optionally, both the ventilation frame and the inner barrier plate have limit holes, the inside of which is bonded with a sealing gasket, and the outside of the airbag is fitted with a positioning element that passes through the limit hole.

[0013] Optionally, the positioning element includes: The insertion post is installed on the airbag; The threaded post is fixedly mounted on the plug post and inserted into the inside of the limiting through hole; A threaded sleeve is screwed onto the outside of a threaded post and pressed against a sealing gasket.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-7 The shown square-cell ventilation duct sealing structure includes: Ventilation component 100; A sealing assembly 200 is installed at the vent of the ventilation assembly 100 and is used to block the vent of the ventilation assembly 100. Because existing sealing components 200 tend to loosen under prolonged compression, resulting in reduced sealing performance, this invention features a specially designed airbag 210 with a subordinate structure to provide compression force and ensure sealing performance by filling in gas when the air pressure decreases, eliminating the need to replace the structure in the sealing component 200.

[0024] The sealing assembly 200 includes: Airbag 210, which is installed inside the ventilation assembly 100; The sealing rubber 220 is bonded to the outside of the airbag 210. The sealing rubber 220 is squeezed and sealed with the ventilation component 100 to ensure complete sealing and prevent air leakage. The airbag 210 expands and applies pressure to the sealing rubber 220, so that the sealing rubber 220 can achieve the sealing effect without relying on its own large deformation, thus preventing the sealing rubber 220 from being compressed and relaxed over a long period of time. Multiple pressure sensing devices 230 are provided and bonded between the airbag 210 and the sealing rubber 220. They are used to monitor and calculate the air pressure inside the airbag 210 in real time, thereby ensuring the stability and reliability of the sealing effect.

[0025] In this process, the airbag 210 is inflated and expands, causing the sealing rubber 220 to be squeezed and sealed with the ventilation component 100. By utilizing the elasticity of the airbag 210 and the properties of the sealing rubber 220, the gaps in the ventilation opening can be effectively filled, achieving a good sealing effect and preventing air, dust, etc. from entering the square compartment.

[0026] Multiple pressure sensing devices 230 can monitor the internal air pressure of the airbag 210 in real time, promptly detect problems such as air leakage and reduced air pressure, and facilitate timely maintenance or replacement by staff to ensure the reliability of the sealing structure.

[0027] The working principle of this embodiment is as follows: In use, the airbag 210 is installed inside the ventilation assembly 100, and then gas is injected into the airbag 210. The airbag 210 expands under the action of the gas and causes the sealing rubber 220 to be squeezed against the ventilation assembly 100 to form a seal. At this time, the pressure sensing device 230 is simultaneously pressurized and transmits the pressure via Bluetooth. Based on the pressure, the sealing status data is indicated to warn of leakage risk. When the pressure displayed by the pressure sensing device 230 decreases, a certain amount of gas is injected into the airbag 210.

[0028] In some embodiments of this utility model, reference is made to Figure 2 and Figure 7As shown, L-shaped plates 240 are bonded to the four outer corners of the airbag 210, which can enhance the stability and strength of the structure and provide support for the airbag 210. This makes the airbag structure more stable and less prone to deformation during inflation and use. Each pair of adjacent L-shaped plates 240 are connected by a plastic plate 250. The L-shaped plates 240 can be folded together by relying on the deformation characteristics of the plastic plate 250.

[0029] In some embodiments of this utility model, reference is made to Figure 2 and Figure 7 As shown, the plastic sheet 250 has multiple triangular grooves 260 for bending and folding.

[0030] The triangular groove 260 facilitates the bending and folding of the plastic plate, adapts to the expansion and contraction of the airbag 210, and allows the plastic plate 250 to bend and fold normally when retracted, so that the airbag 210 can be folded together, reducing the area occupied by the airbag 210 and making it convenient to carry and deploy the airbag 210.

[0031] In some embodiments of this utility model, reference is made to Figure 2 As shown, the ventilation assembly 100 includes: The ventilation frame 110 serves as the skeleton of the entire ventilation system, supporting and fixing other components. The ventilation frame 110 is installed on the wall of the square compartment, with the opening located on the outside of the square compartment. The door panel 120 is hinged to the ventilation opening of the ventilation frame 110 and is pressed against the sealing rubber 220 and the airbag 210 to ensure effective sealing when closed and prevent air leakage. The door panel 120 is also equipped with a locking structure for fixing the door panel 120 to the ventilation frame 110. The inner baffle plate 130 is installed inside the ventilation frame 110 and works with the ventilation frame 110 to hold the airbag 210. It guides the expansion direction of the airbag 210, so that the airbag 210 can drive the sealing rubber 220 and the airbag 210 to squeeze against the door panel 120 when it is filled with gas. Multiple accumulator components 140 are provided and installed on the ventilation frame 110 to apply compressive force to the airbag 210. By adjusting the force of the accumulator components 140, the expansion degree of the airbag 210 can be precisely controlled to further optimize the sealing performance. When the airbag 210 leaks gas, the stress of the accumulator components 140 is released and compresses the airbag to ensure the sealing effect.

[0032] In some embodiments of this utility model, reference is made to Figure 5 As shown, the energy storage assembly 140 includes: Compression spring 141 is installed inside the ventilation frame 110 and is used to apply compression force to airbag 210 to ensure that airbag 210 is compressed when gas leaks inside airbag 210, so that airbag 210 and sealing rubber 220 can still maintain sealing performance. The pad 142 is fixedly mounted on the compression spring 141 and contacts the airbag 210. The pressure of the compression spring 141 is transmitted through the pad 142, protecting the airbag 210 from direct wear.

[0033] The working principle of this embodiment is as follows: When the airbag 210 is inflated, it will compress the pad 142, causing the pad 142 to compress the spring 141 and store force. When the airbag 210 leaks, the spring force of the spring 141 will be released, and the airbag 210 will be pushed to compress the door panel 120, thereby reducing the impact of the airbag 210 gas leakage.

[0034] In some embodiments of this utility model, reference is made to Figure 2 As shown, both the ventilation frame 110 and the inner baffle plate 130 have limiting through holes 150. The limiting through holes 150 are used for precise alignment and fixing of related components. A sealing gasket 160 is bonded inside the limiting through hole 150. The function of the sealing gasket 160 is to prevent gas leakage and ensure the airtightness of the system. A positioning member 170 is installed on the outside of the airbag 210, which passes through the limiting through hole 150. The positioning member 170 not only serves to fix the airbag 210, but also ensures that the airbag 210 remains stable during operation and will not shift or deform.

[0035] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, the positioning element 170 includes: The insertion post 171 is mounted on the airbag 210 to ensure a secure connection between the positioning member 170 and the airbag 210. The threaded post 172 is fixedly installed on the plug post 171 and inserted into the limiting through hole 150. The insertion of the threaded post 172 restricts the movement range of the airbag 210. The threaded sleeve 173 is screwed onto the outside of the threaded post 172 and is pressed against the sealing gasket 160. The engagement between the threaded sleeve 173 and the threaded post 172 ensures the stability of the insertion post 171 after insertion.

[0036] The working principle of this embodiment is as follows: During installation, insert the plug post 171 and the threaded post 172 into the inside of the limiting through hole 150, and then screw the threaded sleeve 173 onto the outside of the threaded post 172, pressing it against the ventilation frame 110 and the sealing gasket 160.

[0037] In some embodiments of this utility model, reference is made to Figure 4 As shown, a gas-sensitive core 211 is provided on the outside of the airbag 210. Gas can be injected into the airbag 210 through the gas-sensitive core 211, causing the airbag 210 to expand under the action of the gas. At the same time, it can be sealed during normal use to prevent gas leakage. The gas-sensitive core 211 extends to the outside of the ventilation assembly 100.

[0038] In some embodiments of this utility model, reference is made to Figure 6 As shown, both the sealing rubber 220 and the airbag 210 are composed of an anti-aging layer, a highly elastic foamed rubber, and a corrosion-resistant layer bonded together from the outside to the inside.

[0039] Among them, the anti-aging layer is made of EPDM rubber, which is resistant to ultraviolet rays, ozone and extreme temperatures of -40℃ to 120℃; the high-elasticity foamed rubber fills gaps and buffers deformation pressure, improving the sealing tightness; and the corrosion-resistant layer is made of fluororubber FKM, which is resistant to fumigation gases and chemical corrosion.

[0040] In some embodiments of this utility model, reference is made to Figure 4 As shown, the pressure sensing device 230 uses an embedded miniature pressure sensor to transmit sealing status data via Bluetooth and provide early warning of leakage risks.

[0041] When abnormal pressure or potential leakage risk is detected, an alarm will be issued in a timely manner to remind users to take appropriate measures, thereby effectively preventing leakage accidents from occurring.

[0042] The working method of this utility model: Open the door panel 120, then install the sealing assembly 200 between the inner barrier plate 130 and the ventilation frame 110, and insert the plug post 171 and threaded post 172 into the limiting through hole 150. Then screw the threaded sleeve 173 onto the outside of the threaded post 172 and press it against the ventilation frame 110, and the gas-sensitive core 211 passes through the ventilation frame 110. Close the door panel 120, and then inflate the airbag 210 by injecting gas into the airbag 210 through the gas-sensitive core 211. The sealing rubber 220 is pressed tightly against the door panel 120 to seal the ventilation duct. The pressure sensing device 230 monitors the internal air pressure of the airbag 210 in real time. If the air pressure is abnormal, the staff can check and repair it in time. When the airbag 210 expands, it will also press the pad 142, causing the pad 142 to slide and press the compression spring 141, which will compress and store force. When the air pressure of the airbag 210 decreases, the elastic force of the compression spring 141 will be released to ensure that the sealing rubber 220 is pressed tightly against the door panel 120.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
