Description

Technical Field

[0001] The present invention relates to the technical field of green house structures, and in particular to a heat-insulating and energy-saving assembled green house. Background Art

[0002] In energy-saving buildings, prefabricated buildings or industrial wall systems, the design of multi-layer composite walls is particularly applicable; multi-layer composite walls have the advantages of energy saving and environmental protection. The outer channel is filled with insulation materials to form a thermal bridge effect, which can also reduce energy consumption, while the inner channel can reduce the risk of condensation due to the temperature difference between indoor and outdoor. The existing multi-layer composite wall is generally composed of a main wall, an inner wall and an outer wall, and the outer wall is generally composed of an adhesive layer, an insulation layer, a plaster layer and a finishing layer, wherein the insulation layer is mostly spliced ​​by insulation boards. At present, in actual on-site construction, the gap is usually controlled by brushing an interface agent on the board joints and then filling polyurethane foam. The above treatment of the insulation board gap is suitable for a small-sized insulation layer structure. For a large modular assembled insulation wall, the insulation layer of the entire wall is composed of one or two prefabricated insulation boards. This setting can effectively form an insulation barrier for the wall, thereby enhancing the practicality of the insulation system. However, the method of filling polyurethane foam is less effective in controlling large-sized gaps in terms of cost and technology.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0016] Please refer to Figure 1-Figure 11 A thermal insulation and energy-saving assembled green house, the wall of the green house is spliced ​​by assembled insulation walls, the insulation wall is composed of a wall main board 1, an insulation structure 2 arranged on the outside of the wall main board 1 and an inner wall decorative panel arranged on the inside of the wall main board 1; the insulation structure 2 includes an insulation frame 201, and the insulation frame 201 is filled with insulation material; a sealing structure 3 is provided between the two insulation frames 201, and the sealing structure 3 can ensure the airtightness between the two insulation frames 201 at different temperatures.

[0017] The walls of traditional prefabricated green houses are mostly composed of three parts, namely the main wall, the inner wall and the outer wall. The outer wall is generally composed of an adhesive layer, an insulation layer, a plaster layer and a finishing layer. The insulation layer is mostly made of insulation boards. Due to the material expansion coefficient and the temperature difference between indoor and outdoor, there are certain gaps at the joints of the insulation boards. At present, in actual on-site construction, the gaps are usually controlled by applying an interface agent to the board joints and then filling them with polyurethane foam glue, which can effectively resolve the risks caused by thermal expansion and contraction and ensure the long-term stability of the insulation system. The above-mentioned treatment of the gaps in the insulation boards is suitable for small-sized insulation layer structures. For large modular prefabricated insulation walls, the insulation layer of the entire wall is composed of one or two prefabricated insulation boards. This arrangement can effectively form an insulation barrier for the wall, thereby enhancing the practicality of the insulation system. However, the method of filling polyurethane foam to control large-sized gaps is less effective in terms of cost and technology. It is usually necessary to add a combination of glass fiber mesh cloth + anti-cracking mortar to ensure the insulation performance of large-sized 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 when the temperature difference between indoor and outdoor is large, the air tightness between adjacent insulation structures 2 can still be guaranteed, thereby ensuring the insulation performance of the green house. Example

[0018] Please refer to Figure 2-Figure 4 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0019] As a further technical solution of this embodiment, the insulation structure 2 also includes connecting parts 202 arranged at the four inner corners of the insulation frame 201, and the connecting parts 202 are fixed to the insulation frame 201 through reinforcing ribs; a reinforcing rod 203 is provided on the insulation frame 201, and a connecting plate 204 is provided in the middle of the reinforcing rod 203; a low-pressure air cylinder 205 is provided between the connecting plate 204 and the two top connecting parts 202, and a high-pressure air cylinder 206 is provided between the connecting plate 204 and the two bottom connecting parts 202, and connecting heads 207 are rotatably provided at both ends of the low-pressure air cylinder 205 and the high-pressure air cylinder 206; the connecting heads 207 of the low-pressure air cylinder 205 and the high-pressure air cylinder 206 are respectively fixed to the connecting parts 202 and the connecting plates 204 by locking bolts.

[0020] Furthermore, the low-pressure gas cylinder 205 and the high-pressure gas cylinder 206 are placed as a whole in the insulation material in the insulation frame 201. The insulation material in the insulation frame 201 is composed of a powdered silica core material and a getter. A composite gas barrier film is also provided on the insulation frame 201 as a wrapping material to fix the insulation material to the inner side of the insulation frame 201.

[0021] Furthermore, the gas pressure in the high-pressure gas cylinder 206 is greater than the outdoor standard atmospheric pressure, and the gas pressure in the low-pressure gas cylinder 205 is less than the outdoor standard atmospheric pressure. The high-pressure gas guiding channel and the negative-pressure gas guiding channel are symmetrically arranged as a whole.

[0022] As can be seen from the above, the thermal insulation structure 2 of the present invention is composed of a thermal insulation frame 201 and a thermal insulation material filled in the thermal insulation frame 201. Further, the thermal insulation material in the thermal insulation frame 201 is composed of a powdered silica core material and a getter, and the thermal insulation material is fixed to the inner side of the thermal insulation frame 201 by using a composite gas barrier film as a wrapping material. This arrangement allows the thermal insulation frame 201 and the thermal insulation material to form a unified whole, and then be arranged on the outer side of the wall main board 1, which is equivalent to the existing thermal insulation board structure; In order to enable the sealing structure 3 to work normally, a low-pressure gas cylinder 205 and a high-pressure gas cylinder 206 that provide power for the sealing structure 3 are arranged in the insulation frame 201. The specific arrangement is as follows: since both ends of the low-pressure gas cylinder 205 and the high-pressure gas cylinder 206 are rotatably provided with connectors 207, the low-pressure gas cylinder 205 and the high-pressure gas cylinder 206 are fixed between the connecting piece 202 and the connecting disk 204 through the provided connectors 207. The general working principle is: when the external ambient temperature is low, in a sealed container, the volume of the sealed container is fixed and the gas mass is unchanged, the gas pressure is proportional to the absolute temperature, that is, the gas in the low-pressure gas cylinder 205 and the high-pressure gas cylinder 206 is affected by the low temperature, thereby causing the air pressure to drop; when the external ambient temperature is high, the gas in the low-pressure gas cylinder 205 and the high-pressure gas cylinder 206 is affected by the external high temperature, thereby causing the air pressure to rise. The present invention ensures that the sealing structure 3 can make adaptive changes according to the external environment through pressure changes. Example

[0023] Please refer to Figure 4-Figure 11 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0024] As a further technical solution of this embodiment, the sealing structure 3 includes an embedded part arranged in the wall main board 1, and two limit members 301 are arranged on the embedded part. Two adjacent insulation frames 201 are slidably arranged between the two limit members 301. The two insulation frames 201 are provided with L-shaped sealing plates 302 used in conjunction with each other, and the two L-shaped sealing plates 302 abut against each other, and a sealing strip 3021 is provided at the abutment. A sealing column 303 is provided between the two stoppers 301, and two long sealing plates 304 and two short sealing plates 305 are slidably provided on the sealing column 303. The two long sealing plates 304 and the two short sealing plates 305 are arranged alternately, and a rubber sealing plate is provided at one end of the long sealing plate 304 and the short sealing plate 305 that are in contact with the L-shaped sealing plate 302. A rectangular slide groove is provided on the sealing column 303 to cooperate with the long sealing plate 304 and the short sealing plate 305 to slide, and an oil seal strip is provided on the inner wall of the rectangular slide groove to enhance the sealing performance; A high-pressure driving component for driving the long sealing plate 304 to move is disposed in the sealing column 303 , and a low-pressure driving component for driving the short sealing plate 305 to move is also disposed in the sealing column 303 .

[0025] As can be seen from the above, two adjacent insulation frames 201 are slidably arranged between two limit members 301, and the limit members 301 are arranged on the embedded parts, so the insulation frames 201 can be designed according to the size of the wall main board 1 to meet the assembly requirements of the green house, so that the installation can be carried out 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 arranged between them, and a 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 arranged at the abutment between the two to effectively ensure the mutual fit of the two vertical surfaces; The temperature difference between the two L-shaped sealing plates 302 will cause a certain movement between the two, and this movement will destroy the sealing structure formed between the two. For example, when the outdoor ambient temperature is too high, the thermal insulation frame 201 will expand as a whole due to the heat, and then the two L-shaped sealing plates 302 will be squeezed against each other, thereby destroying the sealing structure. For example, when the outdoor ambient temperature is too low, the thermal insulation frame 201 will shrink as a whole due to pre-cooling, and a relative gap will be generated between the two L-shaped sealing plates 302 that were originally abutting against each other. At this time, air will pass through between the two, resulting in poor stability of the thermal insulation system. In order to solve the above problem, a sealing column 303 is provided between the two stoppers 301, and two long sealing plates 304 and two short sealing plates 305 are slidably provided on the sealing column 303. The two long sealing plates 304 and the two short sealing plates 305 are arranged in a staggered manner. In the projection of the vertical plane, the two long sealing plates 304 and the two short sealing plates 305 are arranged in a "cross" shape (such as Figure 4As shown); the advantage of this arrangement is that when the two L-shaped sealing plates 302 are heated and close to each other, the two long sealing plates 304 can extend to 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 thermal insulation layer at high temperature is effectively guaranteed; When the two L-shaped sealing plates 302 come into contact with each other when cold, the two short sealing plates 305 can extend to abut 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

[0026] Please refer to Figure 4-Figure 11 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0027] 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 alternately; The high-pressure driving assembly includes a cylindrical cavity arranged in the high-pressure driving section 3031. The high-pressure driving section 3031 also includes a plurality of piston cavities, and the plurality of piston cavities are interconnected with the cylindrical cavity. A piston push column 306 is slidingly arranged in the piston cavity. The piston push column 306 is fixedly arranged with a long sealing plate 304 arranged on the same side. A high-pressure gas guide channel is arranged in the sealing column 303. The plurality of cylindrical cavities are interconnected through the high-pressure gas guide channel. A high-pressure connecting pipe 307 is provided on the sealing column 303. The high-pressure gas storage cylinder 206 is interconnected with the high-pressure gas guide channel through the high-pressure connecting pipe 307.

[0028] As can be seen from the above, the working principle of the two long sealing plates 304 extending is specifically as follows: when the outside temperature increases, the temperature will be transferred to the high-pressure gas storage cylinder 206 in the heat preservation frame 201. Since the volume of the high-pressure gas storage cylinder 206 is fixed but a certain mass of inert gas is filled inside, when the temperature rises, the gas pressure in the high-pressure gas storage cylinder 206 increases. Since the high-pressure gas storage cylinder 206 is interconnected with the high-pressure gas guide channel through the high-pressure connecting pipe 307, the pressure in the entire high-pressure gas guide channel increases. Since several cylindrical cavities are interconnected through high-pressure gas guide channels, the pressure of the cylindrical cavity in the high-pressure driving section 3031 is further increased. When the gas pressure in the cylindrical cavity increases, the gas will push the piston push rod 306 to move outward, and the piston push rod 306 is fixed to the long sealing plate 304, which makes the long sealing plate 304 extend from the sealing column 303. The above process is a movement description of the extension of the two long sealing plates 304. During this process, the two short sealing plates 305 show a relative contraction movement trend.

[0029] Further, the low-pressure driving assembly includes a plurality of negative pressure chambers arranged in the low-pressure driving section 3032, two T-shaped negative pressure push pins 308 are slidably arranged in the negative pressure chamber, and the T-shaped negative pressure push pins 308 are fixedly arranged with the short sealing plate 305 arranged on the same side, and a compression spring 309 is arranged between the two T-shaped negative pressure push pins 308; A negative pressure air guide channel is provided in the sealing column 303, and several negative pressure chambers are interconnected through the negative pressure air guide channel. A negative pressure connecting pipe 310 is provided on the sealing column 303, and the low-pressure air storage cylinder 205 is interconnected with the negative pressure air guide channel through the negative pressure connecting pipe 310.

[0030] Furthermore, a positioning bolt is provided on the limiting member 301 , and the heat preservation frame 201 is fixed to the limiting member 301 via the positioning bolt.

[0031] As can be seen from the above, the specific principle of the extension of the two short sealing plates 305 is: when the external environment temperature decreases, the overall temperature of the low-pressure gas storage cylinder 205 arranged in the heat preservation frame 201 will decrease, which will cause the air pressure inside the low-pressure gas storage cylinder 205 to decrease. Compared with the air pressure of the low-pressure gas storage cylinder 205 at the beginning, the air pressure of the low-pressure gas storage cylinder 205 after cooling is smaller. Since the low-pressure gas storage cylinder 205 is interconnected with the negative pressure gas guide channel through the negative pressure connecting pipe 310, and several negative pressure chambers are interconnected through the negative pressure gas guide channel, the air pressure of the low-pressure gas storage cylinder 205 will be quickly transmitted to the negative pressure chamber. Since there is gas in the negative pressure chamber, when the air 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 channel openings for gas extraction are located on both sides of the negative pressure chamber, such as Figure 7As shown), this causes the two sliding T-shaped negative pressure push columns 308 to move away from each other, and further, the T-shaped negative pressure push column 308 is fixed to the short sealing plate 305 set on the same side, so when the external temperature decreases, the short sealing plate 305 will extend from the sealing column 303, and then abut the two L-shaped sealing plates 302, further forming a sealing structure, ensuring the effectiveness of adjacent insulation layers. In the present invention, since the change in temperature can lead to the normal operation of the sealing structure 3, the sealing structure 3 of the present invention has a certain degree of adaptability. This arrangement can greatly reduce production costs, ensure the normal use of the insulation layer, and at the same time accelerate the rapid assembly of green houses.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the above embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiments.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
