Description

Technical Field

[0001] This invention relates to the field of grain warehouse insulation window technology, specifically a hollow insulation window for grain warehouses. Background Technology

[0002] In the daily operation of grain warehouses, insulated and airtight windows are usually installed high up in the walls to facilitate lighting, natural ventilation, and regulation of temperature and humidity inside the warehouse. At the same time, these windows also need to provide necessary isolation and airtightness when carrying out insect fumigation operations.

[0003] Currently, traditional grain depot insulated windows mostly use single-pane glass or single-pane insulation panels. In practical applications, this single-pane window structure creates a significant thermal bridging effect, resulting in weak overall insulation performance. When the external temperature changes significantly, heat can easily be conducted through the window, causing condensation on the inner walls around the window, potentially leading to dampness and mold growth on nearby stored grain. Furthermore, ordinary household double-glazed windows, limited by structural strength, cannot withstand the pressure changes generated during grain depot fumigation operations, while conventional single-pane insulated windows cannot effectively block direct heat conduction. Therefore, existing window systems cannot simultaneously meet the comprehensive requirements of modern grain depots for high strength, high airtightness, and stable temperature control, affecting the long-term safe storage of grain. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a hollow insulated window for grain storage, which solves the problems of poor thermal insulation performance leading to easy condensation on the window, and the inability of existing insulated windows to meet the requirements of grain storage fumigation operations in terms of airtightness and structural strength.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hollow insulated window for grain storage, comprising: Hollow windows, which serve as the main body of the device, are used to insulate the interior of the grain warehouse; The control mechanism is installed on one side of the hollow window and is used to control the opening and closing of the insulated window from a low position. The insulation mechanism, which is filled inside the hollow window, works together to achieve thermal insulation. The control mechanism includes a linkage pipe, which is installed at the top of the hollow window. A control pipe is installed on one side of the linkage pipe, and a manual / automatic window opening component is installed at the end of the control pipe away from the linkage pipe.

[0006] Preferably, the outer wall of the linkage tube is provided with an adjustable hinge, the adjustable hinge is installed on the outside of the hollow window, a support tube is installed at the bottom of the adjustable hinge, a support tube is rotated at the end of the support tube away from the adjustable hinge, and the relative position between the support tube and the support tube is fixed by a spring pin.

[0007] Preferably, the insulation mechanism includes an outer insulation layer, an inner insulation layer, and decorative components; An insulation cavity is provided between the inner insulation layer and the outer insulation layer, and the insulation cavity is filled with inert gas.

[0008] Preferably, the outer insulation layer includes an outer PC board and a polyurethane insulation layer, wherein the outer PC board is disposed inside the hollow window, and the polyurethane insulation layer is disposed on the side of the outer PC board away from the insulation cavity.

[0009] Preferably, the inner insulation layer includes an inner PC board and a second polyurethane insulation layer. The inner PC board is disposed inside the hollow window, and the second polyurethane insulation layer is disposed on the side of the inner PC board away from the insulation cavity.

[0010] Preferably, the decorative component includes an exterior panel and an interior panel, with the exterior panel installed on one side of the outer insulation layer and the interior panel installed on one side of the inner insulation layer.

[0011] This invention provides a hollow insulated window for grain storage. It has the following beneficial effects: 1. This invention forms a multi-layer composite insulation structure by setting polyurethane insulation layer one and polyurethane insulation layer two on the inner and outer sides of the hollow window, and reserving an insulation cavity filled with inert gas in the middle. This reduces the air convection heat transfer coefficient and reduces heat transfer, thereby effectively preventing condensation in the grain storage window area due to the temperature difference between the inside and outside, which is conducive to maintaining the temperature and humidity stability of the grain storage environment.

[0012] 2. This invention separates the polyurethane insulation layer one and polyurethane insulation layer two from the insulation cavity by setting an outer PC board and an inner PC board on both sides of the insulation cavity, thus blocking the direct heat conduction path between them. At the same time, in conjunction with the window frame designed with a thermal break structure, it achieves double thermal insulation of the board and the frame, effectively cutting off the heat conduction path of the metal frame and reducing the impact of thermal bridge effect on the overall insulation performance.

[0013] 3. This invention features metal decorative panels on both the outermost and innermost sides of the hollow window, combined with a multi-layered sealing structure on the window frame, enhancing the overall airtightness and structural compressive strength of the window when closed, thus meeting the stringent sealing and leak-proof requirements of grain warehouse fumigation operations. Furthermore, with the interlocking control mechanism installed on one side of the hollow window, operators can conveniently control the opening and closing of the high-level insulated window from a low position, improving the convenience of daily ventilation and sealing operations.

Detailed Implementation

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please refer to the attached diagram, 1-Appendix Figure 2 This invention provides a hollow insulated window for grain storage, comprising: Hollow window 1, which serves as the main body of the device, is used to insulate the interior of the grain warehouse; The control mechanism is installed on one side of the hollow window 1 and is used to control the opening and closing of the insulated window from a low position. The insulation mechanism, which is filled inside the hollow window 1, works together to enable the hollow window 1 to achieve thermal insulation. The control mechanism includes a linkage pipe 2, which is located at the top of the hollow window 1. A control pipe 4 is located on one side of the linkage pipe 2, and a manual / automatic window opening component 5 is located at the end of the control pipe 4 away from the linkage pipe 2. An adjustable hinge 3 is provided on the outer wall of the linkage pipe 2. The adjustable hinge 3 is installed on the outside of the hollow window 1. A support pipe 6 is installed at the bottom of the adjustable hinge 3. A support pipe 7 is rotated at the end of the support pipe 6 away from the adjustable hinge 3. The relative position between the support pipe 6 and the support pipe 7 is fixed by a spring pin.

[0018] Specifically, when it is necessary to open the window, the manual / automatic window opening component 5 needs to be operated to drive the control tube 4, so that the control tube 4 can control the linkage tube 2 to rotate. At this time, as the linkage tube 2 rotates, the angle of the adjustable hinge 3 changes, so that the support tube 1 6 changes from its original vertical state to a tilted state with a certain angle. At this time, the spring pin between the support tube 1 6 and the support tube 2 7 disengages due to the change in the state of the support tube 1 6, so that the support tube 2 7 can be pulled up, and the angle also changes. Thus, the hollow window 1 is in an open state, which is suitable for normal weather. Before encountering thunderstorms, simply reverse the operation to reconnect the hollow window 1 with the window frame 8 and close it, so that the whole grain warehouse is in a closed state.

[0019] Please see the appendix Figure 3 The insulation structure includes an outer insulation layer, an inner insulation layer, and decorative components; An insulation cavity is provided between the inner insulation layer and the outer insulation layer, and the insulation cavity is filled with inert gas. The outer insulation layer includes an outer PC board 9 and a polyurethane insulation layer 10. The outer PC board 9 is located inside the hollow window 1, and the polyurethane insulation layer 10 is located on the side of the outer PC board 9 away from the insulation cavity. The inner insulation layer includes an inner PC board 11 and a polyurethane insulation layer 12. The inner PC board 11 is located inside the hollow window 1, and the polyurethane insulation layer 12 is located on the side of the inner PC board 11 away from the insulation cavity. The decorative components include an outer trim panel 13 and an interior trim panel 14. The outer trim panel 13 is installed on one side of the outer insulation layer, and the interior trim panel 14 is installed on one side of the inner insulation layer.

[0020] Specifically, this embodiment provides an insulated window, which is installed at a high position on the wall of the grain depot. The total thickness of the hollow window 1 is preferably 80mm. It adopts a composite insulation system by combining the inner and outer double-sided insulation structure with the middle insulation cavity.

[0021] The insulation cavity in the middle is preferably 20mm thick and is filled with an inert gas, such as argon or nitrogen, to reduce the air convection heat transfer coefficient, thereby improving the overall insulation performance and effectively suppressing condensation.

[0022] Thermal insulation interfaces, namely an outer PC board 9 and an inner PC board 11, are respectively provided on both sides of the sealed cavity. These boards, as low thermal conductivity material layers, are arranged at the cavity boundary to block the direct heat transfer path between the polyurethane insulation layer 10 and the polyurethane insulation layer 12 and the cavity. This arrangement reduces the thermal bridging effect, allowing the hollow structure to maintain a dry and stable state over a long period of time.

[0023] The preferred thickness of polyurethane insulation layer 10 and polyurethane insulation layer 12 is 30mm. Polyurethane material has the characteristics of low thermal conductivity and strong integrity. In this embodiment, it is arranged on the inner and outer sides of the window to form the main thermal resistance layer, thereby ensuring that the window still has good thermal insulation ability in low temperature or high humidity environment.

[0024] An exterior trim panel 13 and an interior trim panel 14 are respectively installed on the outermost and innermost sides of the window to form a protective and decorative structure. The exterior trim panel 13 and the interior trim panel 14 are preferably made of color steel plate or stainless steel plate, which can not only improve the overall structural strength, but also enhance weather resistance and corrosion resistance, making them suitable for long-term use in grain depots.

[0025] In addition, the entire hollow window 1 is supported and fixed by a thermally broken aluminum profile frame, namely the window frame 8. The window frame 8 adopts a thermally broken structure design, which effectively cuts off the metal heat conduction path, and with the help of multiple sealing structures, it can form a reliable airtight environment when the window is closed, meeting the sealing performance requirements during the grain depot fumigation operation.

[0026] Through the above structural combination, this embodiment achieves a composite insulation effect of multi-layer heat resistance and airtight isolation under limited thickness conditions. Compared with traditional single-layer structure windows, it can reduce heat transfer efficiency, avoid condensation and temperature difference problems in the window area, thereby improving the stability and safety of the grain storage environment.

[0027] Working principle: When the double-glazed window 1 needs to be opened, it can be controlled manually or automatically via the control tube 4 by selecting the manual or automatic window opening component 5. The control tube 4 drives the linkage tube 2 to rotate. At this time, the rotating linkage tube 2 will start to drive the adjustable hinge 3 connected to it. The rotation of the adjustable hinge 3 causes the tilt angle of the first support tube 6 to change, which in turn causes the tilt angle of the second support tube 7 to change synchronously. At the same time, the second support tube 7 is stretched. In this way, the corresponding position of the double-glazed window 1 will be in the open state, so as to allow ventilation. Conversely, to close it, simply drive the linkage tube 2 in the opposite direction. When the window is closed, the double-glazed window 1 can be protected by the outer trim panel 13 and the interior trim panel 14. Then, the polyurethane insulation layer 10 and the second polyurethane insulation layer 12 provide heat insulation. Finally, the outer PC board 9 and the inner PC board 11 prevent the polyurethane insulation layer 10 and the second polyurethane insulation layer 12 from directly transferring heat to the insulation cavity, thus preventing condensation.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
