Description

Technical Field

[0001] This invention belongs to the field of low-temperature grain storage technology, and specifically relates to a hidden gear electric airtight window for low-temperature grain storage. Background Technology

[0002] Low-temperature grain storage warehouses need to maintain a stable environment of low temperature and low humidity for a long time to inhibit grain respiration and pest breeding. As an important part of the enclosure structure, the doors and windows must have excellent thermal insulation performance, high airtightness and controllable ventilation. Conventional door and window opening methods and insulation structures are difficult to adapt to the use requirements of large temperature difference and high airtightness of grain warehouses, and manual opening and closing is not conducive to centralized environmental management of grain warehouses.

[0003] The existing patent application number 202422205951.4 discloses a thermally insulated aluminum alloy door and window, including a thermally insulated aluminum alloy door frame, a mounting frame fixed to the front of the thermally insulated aluminum alloy door frame, a controller fixed inside the mounting frame, an intelligent thermal insulation mechanism installed inside the thermally insulated aluminum alloy door frame for intelligent adjustment and thermal insulation effect, and a sunshade component installed on the front of the thermally insulated aluminum alloy door frame. The intelligent thermal insulation mechanism includes an adjustment component installed inside the thermally insulated aluminum alloy door frame for automatic adjustment and a thermal insulation sealing component installed inside the thermally insulated aluminum alloy door frame for thermal insulation effect.

[0004] The existing technology has the following drawbacks: It employs a transmission structure consisting of "two adjusting blocks slidingly connected inside the thermally broken aluminum alloy door frame," "teeth fixed to the top wall of the adjusting groove," and "an electric push rod fixed to the right side of the adjusting block." Opening and closing are achieved by the horizontal sliding of the glass frame driven by the meshing of gears and a linear rack. However, in the application environment of low-temperature grain storage warehouses, this technical solution can only achieve horizontal sliding opening within a plane, failing to meet the top-mounted ventilation requirements of grain warehouse roofs and high side walls. The horizontal opening cannot create an upward ventilation path, making it difficult to efficiently remove accumulated heat and moisture from the warehouse. Furthermore, the existing technology only achieves thermal insulation and sealing through double-layer vacuum glass and side sealing strips. The thermally broken aluminum profile lacks an internal insulation structure. Under conditions of significant temperature differences between the inside and outside of the grain warehouse, cold bridges easily form inside the profile, causing condensation. These condensed water droplets directly threaten the safety of stored grain. Additionally, the numerous seams in the sliding doors and windows, and insufficient overall airtightness, exacerbate the loss of cold air inside the warehouse, increasing the energy consumption of low-temperature grain storage operations. Summary of the Invention

[0005] This invention provides a concealed gear-driven electrically sealed window specifically for low-temperature grain storage, which can solve the technical problems of existing sliding thermally broken aluminum alloy doors and windows being unable to meet the top-hung ventilation requirements of the roof and high side walls of low-temperature grain storage warehouses, and having low ventilation, dehumidification and heat removal efficiency.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] This application provides a concealed gear-operated electrically sealed window specifically for low-temperature grain storage, including a window frame, a window sash, and a panel embedded in the window sash. The window sash is hinged to the window frame via a hinge support member, and the window sash can be rotated around the hinge support member to achieve opening and closing. It also includes:

[0008] An electric drive mechanism, comprising a drive motor, a drive gear, and a sector rack, wherein the sector rack is fixedly disposed on the side of the window sash, and the arc trajectory of the sector rack is coaxially disposed with the flipping motion trajectory of the window sash;

[0009] The aforementioned drive gear is connected to the output end of the drive motor, and the drive gear meshes with the sector rack.

[0010] The aforementioned drive motor is fixedly installed on the window frame, and the drive motor drives the window sash to rotate and open / close around the hinged support through gear and rack meshing transmission.

[0011] The above technical solution employs a flip-type transmission structure with a fan-shaped rack and pinion meshing with a drive gear, enabling the top-hung flip-type opening and closing of the window sash. This is suitable for installation on the roof and high side walls of low-temperature grain storage warehouses. When opened, it forms an upward ventilation path, improving the efficiency of removing accumulated heat and moisture from the warehouse and meeting the requirements for ventilation, temperature control, and humidity control in grain storage. At the same time, the use of electric drive replaces manual operation, making it compatible with centralized and automated environmental management systems for grain warehouses. This reduces the workload of maintenance personnel and improves the response speed and accuracy of ventilation control.

[0012] In this invention, the above-mentioned electric drive mechanism is provided in two sets, which are symmetrically arranged on both sides of the window sash. The two sets of drive motors operate synchronously, driving the window sash to be subjected to force on both sides simultaneously to complete the flipping opening and closing action.

[0013] Through the above technical solution, the symmetrically arranged drive mechanism on both sides can output power synchronously, so that the window sash is subjected to uniform force on both sides during the entire opening and closing process, effectively avoiding the window sash tilting and jamming problems that are prone to occur in single-sided transmission, and improving the stability and reliability of large-size window sash operation; at the same time, the double-sided load-bearing structure can distribute the self-weight load of the window sash, reduce the stress load on the hinge support components, extend the service life of the overall structure, and adapt to the large-size ventilation window size commonly used in low-temperature grain storage warehouses.

[0014] In this invention, the entire panel is filled with thermal insulation material.

[0015] Through the above technical solutions, the overall filling of the panel with insulation material can effectively block the heat conduction path of the panel, reduce the heat transfer coefficient of the entire window, reduce the heat transfer caused by the temperature difference between the inside and outside of the warehouse, maintain the stability of the low temperature environment inside the warehouse, and reduce the energy consumption of refrigeration operation for low-temperature grain storage; at the same time, it can prevent condensation from occurring on the inner side of the panel due to the temperature difference between the inside and outside, prevent condensation water droplets from contaminating the grain, and ensure the quality and safety of stored grain.

[0016] In this invention, the aforementioned hinge support is an adjustable hinge, and the adjustable hinge is provided with a gap adjustment structure for finely adjusting the mating gap between the window sash and the window frame.

[0017] Through the above technical solution, the adjustable hinge gap adjustment structure can finely adjust the fit gap between the window sash and the window frame during the installation and operation and maintenance stages, compensate for the profile processing error and on-site installation deviation, ensure that the surrounding sealing strip is evenly stressed when the window sash is closed, avoid cold leakage and external moisture infiltration caused by excessive local gaps, improve the sealing reliability of the entire window, and adapt to the high airtightness requirements of low-temperature grain storage warehouses.

[0018] In this invention, a window sash rubber strip is provided around the closed end face of the window sash, and the closed end face of the window sash adopts an arc-shaped corner at the corner position. When the window sash is closed, the window sash rubber strip is pressed tightly against the window frame to form a continuous and closed sealing interface.

[0019] Through the above technical solution, the surrounding window sash rubber strips, combined with the seamless structure of the arc-shaped corners, can form a continuous and sealed interface when the window sash is closed, eliminating sealing breaks at the corners, effectively improving the airtightness and watertightness of the entire window, reducing the loss of cold air inside the storage room, and at the same time blocking external moisture, dust and pests from entering the storage room, ensuring a low-temperature and dry grain storage environment inside the storage room, and reducing the risk of mold and pests in the stored grain.

[0028] Example:

[0029] Please refer to Figures 1 to 2 , Figures 1 to 2 The image shown is an embodiment of this application.

[0030] This embodiment provides a concealed gear-operated electrically sealed window specifically for low-temperature grain storage, including a window frame 101, a window sash 102, and a panel 103 embedded in the window sash 102. The window sash 102 is made of thermally broken aluminum profile. The window sash 102 is hinged to the window frame 101 via a hinge support member. The window sash 102 can be rotated around the hinge support member to achieve opening and closing. It also includes:

[0031] The electric drive mechanism includes a drive motor 106, a drive gear 107, and a sector rack 108. The sector rack 108 is fixedly installed on the side of the window sash 102, and the arc trajectory of the sector rack 108 is coaxially arranged with the flipping motion trajectory of the window sash 102. A toothed box 110 is also connected to the side of the window frame 101 away from the window sash 102. The toothed box 110 accommodates the sector rack 108 when the window sash 102 is closed. It should be noted that the side wall with the reserved installation opening will have a pre-set installation groove for the electric drive mechanism and the toothed box 110. At the same time, the length of the sector rack 108 is also less than the wall thickness, so that the sector rack 108 will not extend into the room after the window sash 102 is closed.

[0032] The aforementioned drive gear 107 is connected to the output end of the drive motor 106, and the drive gear 107 meshes with the sector rack 108.

[0033] The aforementioned drive motor 106 is fixedly installed on the window frame 101. The drive motor 106 drives the window sash 102 to rotate and open and close around the hinge support through gear and rack meshing transmission. For example, the drive motor 106 is a DC geared motor. It should be emphasized that the power supply and control method of the drive motor 106 are not within the protection scope of this application. The specific power supply and control method can be obtained or directly purchased by those skilled in the art without creative work, and therefore will not be further described or specifically limited here.

[0034] Through the above technical solution, a flip-type transmission structure in which a sector rack 108 meshes with a drive gear 107 can realize the upward-suspension flip-opening and closing of the window sash 102. This is suitable for installation on the roof and high side walls of low-temperature grain storage warehouses. When opened, it can form an upward ventilation path, improve the efficiency of heat and moisture removal inside the warehouse, and meet the requirements of ventilation, temperature control, and humidity control for grain storage. At the same time, the use of electric drive to replace manual operation can be adapted to the centralized and automated environmental management system of grain warehouses, reduce the operational intensity of maintenance personnel, and improve the response speed and accuracy of ventilation control.

[0035] As a preferred embodiment, the above-mentioned electric drive mechanism is provided in two sets, which are symmetrically arranged on both sides of the window sash 102. The two sets of drive motors 106 operate synchronously, driving the window sash 102 to be simultaneously subjected to force on both sides to complete the flipping opening and closing action.

[0036] Through the above technical solution, the symmetrically arranged drive mechanism on both sides can output power synchronously, so that the window sash 102 is subjected to uniform force on both sides during the entire opening and closing process, effectively avoiding the problems of window sash 102 tilting and jamming that are prone to occur in single-sided transmission, and improving the stability and reliability of the operation of large-size window sash 102; at the same time, the double-sided load-bearing structure can distribute the self-weight load of window sash 102, reduce the stress load on hinge support components, extend the service life of the overall structure, and adapt to the large-size ventilation window size commonly used in low-temperature grain storage warehouses.

[0037] As a preferred embodiment, the panel 103 is entirely filled with thermal insulation material.

[0038] Through the above technical solution, the overall filling of the panel 103 with insulation material can effectively block the heat conduction path of the panel 103, reduce the heat transfer coefficient of the entire window, reduce the heat transfer caused by the temperature difference between the inside and outside of the warehouse, maintain the stability of the low temperature environment inside the warehouse, and reduce the energy consumption of refrigeration operation for low temperature grain storage; at the same time, it can prevent condensation from occurring on the inner side of the panel 103 due to the temperature difference between the inside and outside, prevent condensation water droplets from contaminating the grain, and ensure the quality and safety of the stored grain.

[0039] In a preferred embodiment, the hinge support is an adjustable hinge 105, which is provided with a gap adjustment structure for fine-tuning the fit gap between the window sash 102 and the window frame 101.

[0040] Specifically, the adjustable hinge 105 includes a hinge base, within which a central shaft for hinge connection is connected. The central shaft can be adjusted in height and tilt angle relative to the hinge base via two adjusting screws.

[0041] Through the above technical solution, the gap adjustment structure of the adjustable hinge 105 can finely adjust the fit gap between the window sash 102 and the window frame 101 during the installation and maintenance stages, compensate for the profile processing error and on-site installation deviation, ensure that the sealing strip around the window sash 102 is subjected to uniform force when closed, avoid cold leakage and external moisture infiltration caused by excessive local gaps, improve the sealing reliability of the entire window, and adapt to the high airtightness requirements of low-temperature grain storage warehouses.

[0042] In a preferred embodiment, a window sash rubber strip 109 is provided around the closed end face of the window sash 102. The closed end face of the window sash 102 adopts an arc-shaped corner 104 at the corner position. When the window sash 102 is closed, the window sash rubber strip 109 is pressed tightly against the window frame 101 to form a continuous and closed sealing interface.

[0043] Through the above technical solution, the window sash rubber strip 109 arranged around the window sash and the seamless structure of the arc corner 104 can form a continuous and closed sealing interface when the window sash 102 is closed, eliminating the sealing breaks at the corner, effectively improving the airtightness and watertightness of the entire window, reducing the loss of cold air inside the warehouse, and blocking external moisture, dust and pests from entering the warehouse, ensuring a low-temperature and dry grain storage environment inside the warehouse, and reducing the risk of mold and pests in the stored grain.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
