Description

Technical Field

[0001] This application belongs to the field of heat preservation device technology, specifically relating to a heat preservation room. Background Technology

[0002] Agricultural greenhouses generally consist of walls and insulation blankets. The walls have insulation cavities and light inlets connected to the insulation walls. The insulation blankets can be extended or rolled up to cover the light inlets or keep them open, so that the crops inside the insulation walls can be kept warm or receive sunlight.

[0003] In related technologies, when insulation blankets are placed on top of walls, they are easily blown away by the edges of the walls in windy, cold, and harsh weather. This allows cold air to seep into the insulation cavity through the gap between the wall and the insulation blankets, reducing the insulation capacity of the insulation room and leading to reduced yields or even crop failure. Summary of the Invention

[0004] To address the technical problem of cold air blowing into greenhouses and affecting crop yields during severe weather conditions of low temperatures and strong winds, this application provides a greenhouse material.

[0005] In a first aspect of this application, a greenhouse is provided, comprising:

[0006] The wall includes a front wall, a rear wall, and two gable walls. The front wall and the rear wall are arranged opposite each other, and the two rear walls are arranged opposite each other along the extension direction of the front wall. The front wall, the rear wall, and the two gable walls together form a heat-insulating cavity with a light inlet.

[0007] An insulation layer is attached to the top of the wall to cover the light inlet.

[0008] The windproof module includes a connecting frame and a windproof plate. The connecting frame is connected to the outer wall of the gable wall. The lower end of the windproof plate covers the gable wall, and the upper end extends out of the gable wall, with a height not lower than the top surface of the insulation layer.

[0009] In some embodiments, the top of the gable wall is arc-shaped, the windbreak plate is rectangular, and multiple windbreak modules are provided, with the multiple windbreak modules arranged sequentially along the extension direction of the top of the gable wall.

[0010] In some embodiments, the windproof module includes a frame and a windproof cloth covering the frame. The lower end of the frame extends out of the windproof cloth, and the portion of the frame extending out of the windproof cloth constitutes the connecting frame. The portion of the frame inside the windproof cloth is a rectangular frame. The windproof cloth and the frame wrapped inside the windproof cloth constitute the windproof plate.

[0011] In some embodiments, two side bars of the rectangular frame, which are arranged opposite to each other along their own length, extend out of the rectangular frame, and the portions of the two side bars extending out of the rectangular frame constitute the connecting frame.

[0012] In some embodiments, the multiple side bars of the rectangular frame are connected by welding.

[0013] In some embodiments, the windproof fabric extends beyond the rectangular frame along its length, and in two adjacent windproof modules, the portion of the windproof fabric of one windproof module extending beyond the rectangular frame overlaps with that of the other windproof module.

[0014] In some embodiments, the portion of the windproof fabric of one of the windproof modules that extends out of the rectangular frame covers the other windproof module.

[0015] In some embodiments, each of the gable walls is provided with multiple of the windproof modules.

[0016] In some embodiments, the connecting frame has at least two rows of connecting holes, each row having multiple connecting holes arranged sequentially along the height direction, and the connecting frame is connected to the gable wall by a connector passing through any of the connecting holes in each row.

[0017] In some embodiments, where the gable wall is a brick-concrete wall, the connector is an expansion bolt.

[0018] The insulated room provided according to the embodiments of this application includes a wall, an insulation layer, and a windproof module.

[0019] The walls are typically erected on the ground and include a front wall, a rear wall, and two gable walls. These walls together form an insulated cavity with light-entry openings. An insulation layer overlaps the top of the walls to cover the light-entry openings, ensuring the temperature inside the cavity is maintained in cold weather and providing suitable growing temperatures for crops. The windproof module includes a connecting frame and a windproof panel. The connecting frame is attached to the outer wall of the gable wall, and the lower end of the windproof panel covers the gable wall, ensuring no gap between them. The upper end extends beyond the gable wall, with a height not lower than the top surface of the insulation layer.

[0020] When strong winds come, the windbreak will block part of the wind, and the remaining wind will rise along the windbreak and interact with the wind above the windbreak to form convection. A windless zone will be formed on the side of the windbreak that is close to the insulation layer, so that the insulation layer will not be lifted, ensuring the overall stability of the insulation layer, ensuring the temperature stability inside the insulated room, and improving the yield of crops.

[0021] The windproof module and the gable wall are separate structures, allowing for secondary construction of the already constructed insulation chamber without the need for rebuilding, thus reducing construction costs. The connecting frame attaches to the outer wall of the gable wall without occupying the space at the top of the gable wall, which can be used entirely to support the insulation layer. This further improves the stability of the overlap between the insulation layer and the gable wall, ensuring temperature stability within the insulation cavity and ultimately increasing crop yields.

[0030] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] The first aspect of this application provides a greenhouse that can be modified based on existing greenhouses, is highly versatile, reduces the risk of cold air entering the insulation cavity through the gap between the gable wall and the insulation quilt, and ensures crop yield.

[0032] Please see Figure 1 The insulated room of this application includes a wall, an insulation layer 30, and a windproof module 20.

[0033] The wall can be a brick-concrete structure, an adobe structure, or a steel frame structure, etc. The wall is generally erected on the ground and includes a front wall, a rear wall, and two gable walls 10. The front wall and the rear wall are set opposite each other, and the two rear walls are set opposite each other along the extension direction of the front wall. The front wall, the rear wall, and the two gable walls 10 together form an insulated cavity with a light inlet.

[0034] The insulation layer 30 can be made of insulating cotton or insulating straw, etc. It can be rolled up for storage or unfolded. The insulation layer 30 overlaps the top of the wall to cover the light inlet, so as to maintain the temperature inside the insulation cavity in cold weather and provide a suitable production temperature for crops.

[0035] Windproof module 20 can prevent cold air from blowing into the gap between the top of the gable wall 10 and the insulation layer 30. Please refer to [link / reference]. Figure 2 The windproof module 20 includes a connecting frame 23 and a windproof plate 24. The connecting frame 23 is connected to the outer wall of the gable wall 10, without occupying the space at the top of the gable wall 10. The top of the gable wall 10 can be used entirely to support the insulation layer 30, further improving the overlap stability between the insulation layer 30 and the gable wall 10. The lower end of the windproof plate 24 covers the gable wall 10, so that there is no gap between the gable wall 10 and the windproof plate 24. The upper end of the windproof plate 24 extends out of the gable wall 10, and the height of the upper end of the windproof plate 24 is not lower than the top surface of the insulation layer 30. When a strong wind comes, the windproof plate 24 will block part of the wind, and the remaining wind will rise along the windproof plate 24 and interact with the wind above the windproof plate 24 to form convection. A windless zone will be formed on the side of the windproof plate 24 close to the insulation layer 30, and the wind will not lift the insulation layer 30, ensuring the overall stability of the insulation layer 30. The windproof module 20 and the gable wall 10 are separate structures, so the already constructed insulation room can be reconstructed without having to rebuild the insulation room, thus reducing construction costs.

[0036] In some embodiments, please refer to Figure 3The top of the gable wall 10 is curved, and the top of the front wall is lower than the top of the rear wall. Generally, the front wall is closer to the south than the north wall. This curved shape of the gable wall 10 increases its surface area, improving the heat storage area and facilitating sunlight entry into the insulated room. Because the top of the gable wall 10 is curved, and the windbreak panel 24 is rectangular, a rectangular windbreak panel 24 is difficult to match the curved top of the gable wall 10. Therefore, multiple windbreak modules 20 are provided, such as three, five, or six. Please refer to [link / reference]. Figure 3 Multiple windproof modules 20 are sequentially arranged along the extension direction of the top of the gable wall 10. This allows the overall structure formed by the multiple windproof modules 20 to fit into the curved top of the gable wall 10, achieving wind protection while reducing the area occupied by the overall structure of the multiple windproof modules 20, thus saving costs. Furthermore, different insulation chambers vary greatly in size, and the length of the gable wall 10 also differs. Using multiple windproof modules 20 allows them to be matched with insulation chambers of different sizes, improving the versatility of the windproof modules 20. In other embodiments, the top of the gable wall 10 is a slope, and the length of the windproof modules 20 is the same as the length of the slope, which also achieves the windproof function for the insulation layer 30.

[0037] In some embodiments, please refer to Figures 4 to 6 The windproof module 20 includes a frame 21 and a windproof cloth 22 covering the frame 21. The windproof cloth 22 can fully cover the frame 21 or partially cover it. The lower end of the frame 21 extends out of the windproof cloth 22, and the portion of the frame 21 extending out of the windproof cloth 22 forms a connecting frame 23. The portion of the frame 21 inside the windproof cloth 22 is a rectangular frame, which simplifies the manufacturing process. The windproof cloth 22 and the frame 21 wrapped within the windproof cloth 22 constitute a windproof plate 24. The windproof cloth 22 can be made of waterproof fabric, such as PVC cloth, and the frame 21 can be made of steel structure, such as Q235B steel structure, to ensure the strength and stability of the frame 21. The width and height dimensions of the frame 21 can also be adjusted according to the usage requirements. In some embodiments, the connecting frame 23 and the windproof plate 24 of the windproof module 20 can be an integral structure, for example, obtained by one-piece molding of plastic. In some other embodiments, the portion of the frame 21 located within the windproof cloth 22 can also be a fan-shaped frame that matches the curved top surface of the gable wall 10, resulting in a better fit.

[0038] In some embodiments, two side members of the rectangular frame, arranged opposite each other along its length, extend out of the rectangular frame. The portions of the two side members extending out of the rectangular frame constitute the connecting frame 23, making the processing of the skeleton 21 more convenient, with fewer steps and higher efficiency. In other embodiments, the rectangular frame and the connecting frame 23 can also be separate structures, connected by welding or screwing, which can also form the windproof module 20.

[0039] In some embodiments, please refer to Figure 6The rectangular frame includes four side bars, namely the first side bar 211, the second side bar 212, the third side bar 213, and the fourth side bar 214. The first side bar 211 and the third side bar 213 are arranged opposite each other, and the second side bar 212 and the fourth side bar 214 are arranged opposite each other. The first side bar 211, the second side bar 212, the third side bar 213, and the fourth side bar 214 are connected sequentially to form a closed arc-shaped frame. The second side bar 212 and the fourth side bar 214 extend out of the third side bar 213, and the portions of the second side bar 212 and the fourth side bar 214 that extend out of the third side bar 213 form a connecting frame 23.

[0040] In some embodiments, the first side rod 211, the second side rod 212, the third side rod 213, and the fourth side rod 214 are welded together in sequence, or they can be bolted together in sequence. This application does not impose any restrictions.

[0041] In some embodiments, along the length of the rectangular frame, the windproof fabric 22 extends out of the rectangular frame. In two adjacent windproof modules 20, the portion of the windproof fabric 22 extending out of the rectangular frame of one windproof module 20 overlaps with that of the other windproof module 20, so that there is no gap between two adjacent windproof modules 20, preventing wind from blowing the insulation layer 30 through gaps. In other embodiments, a transition plate can also be provided between two adjacent windproof modules 20, which can also prevent wind from blowing the insulation layer 30 through gaps.

[0042] In some embodiments, the portion of the windproof cloth 22 of one windproof module 20 extending out of the rectangular frame covers the other windproof module 20, and the windproof cloth 22 is connected to the other windproof module 20 by adhesive or heat welding.

[0043] In some embodiments, each gable wall 10 is provided with multiple windproof modules 20, meaning that both gable walls 10 of the insulation room are connected to multiple windproof modules 20, so that the insulation layer 30 can be prevented from being blown over by the wind on both sides of the insulation room along the length of the rear wall. In other embodiments, only one gable wall 10 is provided with multiple windproof modules 20, and the windproof modules 20 can be set in the direction of the strong wind.

[0044] In some embodiments, please refer to Figure 5 as well as Figure 6The connecting frame 23 has at least two rows of connecting holes 231 to improve the connection stability between the windproof module 20 and the gable wall 10. Each row of connecting holes 231 contains multiple holes, arranged sequentially along the height direction. The connecting frame 23 is connected to the gable wall 10 via a connector 25 passing through any one of the connecting holes 231 in each row, allowing for height adjustment of the windproof module 20 to accommodate insulation layers 30 of different thicknesses, thus enhancing its versatility. In specific implementations, the portions of the second side rod 212 and the fourth side rod 214 extending from the third side rod 213 each have multiple connecting holes 231. The connector 25 can be an expansion bolt or a standard threaded connector 25, enabling the connection between the second side rod 212 and the fourth side rod 214 and the gable wall 10.

[0045] There are many types of greenhouses, such as earthen greenhouses, brick-concrete greenhouses, steel-framed greenhouses, flexible solar greenhouses, insulated arched greenhouses, and multi-span film greenhouses. When the greenhouse is a brick-concrete structure and the gable wall 10 is also a brick-concrete wall, the connector 25 can be an expansion bolt to improve the connection strength between the gable wall 10 and the windproof module 20. When the gable wall 10 has a steel frame, the connector 25 is a threaded component.

[0046] When adding windproof modules 20 to the existing insulated room's gable wall 10, holes can be drilled in the gable wall 10 first, then anchor bolts can be inserted into the holes, and then the windproof modules 20 and the gable wall 10 can be connected by bolts. During the assembly and adjustment process, ensure the verticality and horizontality of the windproof board 24, and connect the windproof cloth 22 to the adjacent windproof modules 20 to ensure the integrity of multiple windproof modules 20 located on the same side of the insulation layer 30.

[0047] The greenhouse provided in this application utilizes windproof modules 20 and raised gable walls 10, improving the safety of the insulation blankets, extending their lifespan, and increasing the greenhouse temperature. It also boasts advantages such as quick construction, reusability, and strong adaptability, meeting modern environmental protection and sustainable development requirements. As the importance of infrastructure construction in facility agriculture continues to increase, market demand will continue to grow. Furthermore, with continuous technological advancements and cost reductions, the application scope of frame-assembled windbreak walls will become even wider.
