Description

Technical Field

[0001] This invention relates to the field of green building structure technology, and in particular to a thermally insulated and energy-saving prefabricated green house. Background Technology

[0002] Multi-layer composite walls are particularly suitable for energy-efficient buildings, prefabricated buildings, or industrial wall systems. Multi-layer composite walls have the advantages of energy saving and environmental protection. Their outer channels are filled with thermal insulation material to block the thermal bridging effect and reduce energy consumption, while the inner channels can reduce the risk of condensation due to temperature differences between indoors and outdoors.

[0003] Existing multi-layer composite walls generally consist of a main wall, inner walls, and outer walls. The outer walls typically consist of an adhesive layer, an insulation layer, a plastering layer, and a finishing layer. The insulation layer is mostly composed of spliced ​​insulation boards. Currently, in actual on-site construction, the common method to control gaps is to apply an interface agent to the board joints and then fill them with polyurethane foam. This method of treating insulation board gaps is suitable for small-sized insulation layer structures. For large modular prefabricated insulated walls, the entire wall insulation layer is composed of one or two prefabricated insulation boards. This setup can effectively form an insulation barrier for the wall, thereby enhancing the practicality of the insulation system. However, controlling large-sized gaps by filling them with polyurethane foam is less effective in terms of cost and technology. Usually, it is necessary to add a combination of fiberglass mesh and crack-resistant mortar to ensure the insulation performance of large-sized gaps. In order to reduce the actual assembly difficulty of green houses while ensuring their insulation and energy saving, a prefabricated green house with insulation and energy saving is proposed.

[0033] The technical solutions of 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. Example

[0034] Please refer to Figures 1-11 A prefabricated green house with thermal insulation and energy saving is disclosed. The walls of the green house are assembled from prefabricated insulated wall panels. The insulated wall panels consist of a main wall panel 1, an insulation structure 2 set on the outside of the main wall panel 1, and an inner wall decorative panel set on the inside of the main wall panel 1. The insulation structure 2 includes an insulation frame 201, which is filled with insulation material. A sealing structure 3 is provided between the two insulation frames 201, which can ensure the airtightness between the two insulation frames 201 at different temperatures.

[0035] The walls of traditional prefabricated green houses are mostly composed of three parts: the main wall, the interior wall, and the exterior wall. The exterior wall is generally composed of an adhesive layer, an insulation layer, a plastering layer, and a finishing layer. The insulation layer is mostly made of spliced ​​insulation boards. Due to the material expansion coefficient and the temperature difference between indoors and outdoors, there are certain gaps at the joints of the insulation boards. Currently, in actual on-site construction, the method of applying an interface agent to the board joints and then filling them with polyurethane foam is usually used to control the gaps. This can effectively mitigate the risks caused by thermal expansion and contraction and ensure the long-term stability of the insulation system.

[0036] The above-mentioned treatment of gaps in insulation boards is suitable for small-sized insulation layer structures. For large modular prefabricated insulated walls, the entire wall insulation layer is composed of one or two prefabricated insulation boards. This setup can effectively form an insulation barrier for the wall, thereby enhancing the practicality of the insulation system. However, controlling large gaps by filling them with polyurethane foam is less effective in terms of cost and technology. Usually, it is necessary to add a combination of fiberglass mesh and crack-resistant mortar to ensure the insulation performance of large gaps. In order to reduce the actual assembly difficulty of green houses and ensure the insulation and energy saving of green houses, an insulation structure 2 is set on the outside of the traditional wall main board 1, and a sealing structure 3 is set between adjacent insulation structures 2. The sealing structure 3 ensures that even when there is a large temperature difference between indoors and outdoors, the adjacent insulation structures 2 can still maintain airtightness, thereby ensuring the insulation performance of green houses. Example

[0037] Please refer to Figures 2-4 This embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

[0038] As a further technical solution of this embodiment, the thermal insulation structure 2 also includes connectors 202 disposed at the four corners inside the thermal insulation frame 201. The connectors 202 are fixedly disposed to the thermal insulation frame 201 by reinforcing ribs. The thermal insulation frame 201 is provided with reinforcing rods 203, and a connecting plate 204 is provided in the middle of the reinforcing rods 203. A low-pressure air storage cylinder 205 is provided between the connecting plate 204 and the two uppermost connectors 202, and a high-pressure air storage cylinder 206 is provided between the connecting plate 204 and the two lowermost connectors 202. Connecting heads 207 are rotatably provided at both ends of the low-pressure air storage cylinder 205 and the high-pressure air storage cylinder 206. The connecting heads 207 of the low-pressure air storage cylinder 205 and the high-pressure air storage cylinder 206 are fixedly disposed to the connectors 202 and the connecting plate 204 respectively by locking bolts.

[0039] Furthermore, the low-pressure gas storage cylinder 205 and the high-pressure gas storage cylinder 206 are placed inside the insulation material within the insulation frame 201. The insulation material inside the insulation frame 201 is composed of powdered silica core material and getter. A composite gas barrier membrane is also provided on the insulation frame 201 as a wrapping material to fix the insulation material inside the insulation frame 201.

[0040] Furthermore, the gas pressure inside the high-pressure gas storage cylinder 206 is greater than the outdoor standard atmospheric pressure, while the gas pressure inside the low-pressure gas storage cylinder 205 is less than the outdoor standard atmospheric pressure. The high-pressure gas guide channel and the negative-pressure gas guide channel are symmetrically arranged.

[0041] As can be seen from the above, the thermal insulation structure 2 in this invention is composed of a thermal insulation frame 201 and thermal insulation material filled in the thermal insulation frame 201. Furthermore, the thermal insulation material in the thermal insulation frame 201 is composed of powdered silica core material and air absorbent. The thermal insulation material is fixed to the inside of the thermal insulation frame 201 by using a composite air barrier film as a wrapping material. This arrangement makes the thermal insulation frame 201 and the thermal insulation material form a unified whole, and then set on the outside of the wall main board 1, which is equivalent to the existing thermal insulation board structure.

[0042] To ensure the proper functioning of the sealing structure 3, a low-pressure gas storage cylinder 205 and a high-pressure gas storage cylinder 206 are installed within the insulation frame 201 to provide power to the sealing structure 3. Specifically, since both ends of the low-pressure gas storage cylinder 205 and the high-pressure gas storage cylinder 206 are rotatably equipped with connectors 207, the low-pressure gas storage cylinder 205 and the high-pressure gas storage cylinder 206 are fixed between the connector 202 and the connecting plate 204 through the connectors 207. The general working principle is as follows: when the ambient temperature is low, in the sealed container, with a fixed volume and constant gas mass, the gas pressure is proportional to the absolute temperature. That is, the gas in the low-pressure gas storage cylinder 205 and the high-pressure gas storage cylinder 206 is affected by the low temperature, resulting in a decrease in gas pressure. When the ambient temperature is high, the gas in the low-pressure gas storage cylinder 205 and the high-pressure gas storage cylinder 206 is affected by the high ambient temperature, resulting in an increase in gas pressure. This invention ensures that the sealing structure 3 can adapt to changes in the external environment through pressure changes. Example

[0043] Please refer to Figures 4-11 This embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

[0044] As a further technical solution of this embodiment, the sealing structure 3 includes an embedded part set in the wall main board 1. The embedded part is provided with two limiting parts 301. Two adjacent insulation frames 201 are slidably set between the two limiting parts 301. The two insulation frames 201 are provided with L-shaped sealing plates 302 that cooperate with each other. The two L-shaped sealing plates 302 abut against each other, and a sealing strip 3021 is provided at the abutment.

[0045] A sealing post 303 is provided between the two limiting members 301. Two long sealing plates 304 and two short sealing plates 305 are slidably provided on the sealing post 303. The two long sealing plates 304 and two short sealing plates 305 are staggered. A rubber sealing plate is provided at the end of the long sealing plate 304 and the short sealing plate 305 that contacts the L-shaped sealing plate 302. A rectangular groove is opened on the sealing post 303 to cooperate with the sliding of the long sealing plate 304 and the short sealing plate 305. An oil seal strip is provided on the inner wall of the rectangular groove to enhance the sealing performance.

[0046] The sealing column 303 is equipped with a high-pressure drive assembly for driving the long sealing plate 304 to move, and the sealing column 303 is also equipped with a low-pressure drive assembly for driving the short sealing plate 305 to move.

[0047] As can be seen from the above, the two adjacent insulation frames 201 are slidably set between the two limiting members 301, and the limiting members 301 are set on the embedded parts. Therefore, the insulation frame 201 can be designed according to the size of the wall main board 1 to meet the prefabricated requirements of green houses, so that it can be installed faster and better on site. Since the contact between the two insulation frames 201 is not direct contact, but an L-shaped sealing plate 302 is set between them. The sealing structure is formed by the mutual abutment between the two L-shaped sealing plates 302. In order to ensure the effective fit between the two L-shaped sealing plates 302, a sealing strip 3021 is set at the abutment of the two to effectively ensure the mutual fit of the two vertical surfaces.

[0048] The temperature difference between the two L-shaped sealing plates 302 can cause some movement between them. This movement can damage the sealing structure between them. For example, when the outdoor temperature is too high, the insulation frame 201 expands due to heat, causing the two L-shaped sealing plates 302 to squeeze against each other, which will damage the sealing structure. For example, when the outdoor temperature is too low, the insulation frame 201 contracts due to pre-cooling, and a relative gap will be generated between the two L-shaped sealing plates 302 that were originally touching each other. At this time, air will pass through the gap between them, resulting in poor stability of the insulation system.

[0049] To solve the above problems, a sealing post 303 is provided between the two limiting members 301, and two long sealing plates 304 and two short sealing plates 305 are slidably arranged on the sealing post 303. The two long sealing plates 304 and two short sealing plates 305 are staggered, and in the vertical projection, the two long sealing plates 304 and two short sealing plates 305 are arranged in a cross shape (e.g., Figure 4 (as shown in the figure). The advantage of this setting is that when the two L-shaped sealing plates 302 are heated and approach each other, the two long sealing plates 304 can extend and squeeze the two L-shaped sealing plates 302, thereby ensuring that the deformation of the L-shaped sealing plates 302 is reduced, that is, the damage to the sealing structure of the two is reduced, and the effectiveness of the insulation layer is effectively guaranteed at high temperature.

[0050] When the two L-shaped sealing plates 302 cool to each other, the two short sealing plates 305 can extend to abut against the two L-shaped sealing plates 302, preventing gas from passing between them and ensuring the effectiveness of the insulation layer of the two L-shaped sealing plates 302 at low temperatures. Example

[0051] Please refer to Figures 4-11 This embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

[0052] As a further technical solution of this embodiment, the sealing column 303 is composed of a high-pressure driving section 3031 and a low-pressure driving section 3032 arranged in an alternating manner;

[0053] The high-pressure drive assembly includes a cylindrical cavity disposed within the high-pressure drive section 3031. The high-pressure drive section 3031 also has several piston chambers, which are interconnected with the cylindrical cavity. A piston pusher 306 is slidably disposed within the piston chamber. The piston pusher 306 is fixedly disposed with a long sealing plate 304 disposed on the same side. A high-pressure air guide channel is disposed within the sealing column 303. The several cylindrical cavities are interconnected through the high-pressure air guide channel. A high-pressure connecting pipe 307 is disposed on the sealing column 303. The high-pressure air storage cylinder 206 is interconnected with the high-pressure air guide channel through the high-pressure connecting pipe 307.

[0054] As can be seen from the above, the working principle of the two long sealing plates 304 is as follows: when the outside temperature increases, the temperature will be transferred to the high-pressure gas storage cylinder 206 inside the insulation frame 201. Since the volume of the high-pressure gas storage cylinder 206 is fixed but it is filled with a certain mass of inert gas, the gas pressure inside the high-pressure gas storage cylinder 206 increases when the temperature rises. Since the high-pressure gas storage cylinder 206 is connected to the high-pressure gas guide channel through the high-pressure connecting pipe 307, the pressure inside the entire high-pressure gas guide channel increases.

[0055] Because several cylindrical cavities are interconnected through high-pressure gas channels, the pressure in the cylindrical cavities within the high-pressure drive section 3031 increases. When the gas pressure inside the cylindrical cavities increases, the gas pushes the piston pusher 306 to move outward. The piston pusher 306 is fixedly mounted with the long sealing plate 304, causing the long sealing plate 304 to extend from the sealing post 303. The above process illustrates the movement of the two long sealing plates 304 extending outward. During this process, the two short sealing plates 305 exhibit a tendency to contract relatively.

[0056] Furthermore, the low-pressure drive assembly includes a plurality of negative pressure chambers disposed within the low-pressure drive section 3032, two T-shaped negative pressure pushers 308 slidingly disposed within the negative pressure chambers, and the T-shaped negative pressure pushers 308 being fixedly disposed with a short sealing plate 305 disposed on the same side, and a compression spring 309 being disposed between the two T-shaped negative pressure pushers 308.

[0057] The sealing column 303 is provided with a negative pressure air guiding channel. Several negative pressure chambers are interconnected through the negative pressure air guiding channel. The sealing column 303 is provided with a negative pressure connecting pipe 310. The low pressure air storage cylinder 205 is interconnected with the negative pressure air guiding channel through the negative pressure connecting pipe 310.

[0058] Furthermore, the limiting member 301 is provided with positioning bolts, and the insulation frame 201 is fixedly set to the limiting member 301 by the positioning bolts.

[0059] As can be seen from the above, the specific principle of the extension of the two short sealing plates 305 is as follows: When the ambient temperature decreases, the overall temperature of the low-pressure gas storage cylinder 205 set in the insulation frame 201 will decrease, which will lead to a decrease in the gas pressure inside the low-pressure gas storage cylinder 205. Compared with the initial gas pressure of the low-pressure gas storage cylinder 205, the gas pressure of the cooled low-pressure gas storage cylinder 205 is smaller. Since the low-pressure gas storage cylinder 205 is interconnected with the negative pressure air guiding channel through the negative pressure connecting pipe 310, and several negative pressure chambers are interconnected through the negative pressure air guiding channel, the gas pressure of the low-pressure gas storage cylinder 205 will be quickly transferred to the negative pressure chamber. Since there was originally gas in the negative pressure chamber, when the gas pressure of the low-pressure gas storage cylinder 205 decreases, the low-pressure gas storage cylinder 205 will extract the original gas in the negative pressure chamber (since the gas extraction channel is located on both sides of the negative pressure chamber, such as...). Figure 7As shown in the figure, this causes the two sliding T-shaped negative pressure pushers 308 to move away from each other. Furthermore, the T-shaped negative pressure pushers 308 are fixedly set with the short sealing plate 305 set on the same side. Therefore, when the outside temperature drops, the short sealing plate 305 will extend from the sealing post 303 and then abut against the two L-shaped sealing plates 302 to further form a sealing structure, ensuring the effectiveness of the adjacent insulation layers. In this invention, since the temperature change can cause the sealing structure 3 to work normally, the sealing structure 3 of this invention has a certain degree of self-adaptability. This setting can greatly reduce production costs, ensure the normal use of the insulation layer, and also accelerate the rapid assembly of green houses.
