Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and more specifically to a heat insulation device for green and energy-saving prefabricated buildings. Background Technology

[0002] Prefabricated buildings are constructed by assembling prefabricated components on-site through system integration, achieving prefabrication of the main structural components, non-load-bearing enclosure walls and interior partition walls without masonry, and full interior decoration. Among these, prefabricated walls are a major component of prefabricated buildings, and their performance directly affects the overall quality and user comfort of the building.

[0003] Currently, existing prefabricated walls typically incorporate an internal layer of insulation material to isolate indoor and outdoor heat, achieving energy-saving and heat-preserving effects. However, in practical use, it has been found that while these insulation materials can block heat transfer to some extent, external heat gradually accumulates near the insulation material over time, creating a localized heat buildup effect. With prolonged use, this heat buildup effect intensifies, leading to a gradual decline in the insulation performance of the material and even premature failure. For building envelope structures, insulation material is a critical functional layer; a shortened lifespan directly impacts the overall service life of the prefabricated wall system, increasing subsequent maintenance and replacement costs.

[0004] Furthermore, the insulation materials used in existing prefabricated walls are mostly passive insulation layers with fixed insulation coefficients, unable to adaptively adjust to changes in outdoor temperature. In other words, the insulation material maintains the same insulation capacity regardless of whether it's high in summer or low in winter. When the external temperature is low, excessive insulation may actually hinder the proper dissipation or absorption of heat indoors, which is detrimental to the dynamic balance of the indoor thermal environment; while when the external temperature is high, insulation materials with fixed parameters are unable to cope with extreme high-temperature conditions, and the insulation effect cannot be further improved. This lack of adjustable insulation method further limits the actual use effect of insulation materials and makes it difficult to meet the differentiated requirements for the thermal performance of prefabricated walls under different climatic conditions.

[0021] 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.

[0022] like Figures 1-5 As shown, a heat insulation device for a green and energy-saving prefabricated building includes an outer frame 1, and the device further includes: Water storage tank 2 is installed inside the outer frame 1. Water storage tank 2 is filled with water. A vent pipe 21 is provided on the top of water storage tank 2. Heat insulation component 1 9 and heat insulation component 2 10 are provided. The water storage tank 2 is provided with U-shaped heat insulation component 1 9 on the outside and heat insulation component 2 10 is provided inside the outer frame 1. Two sets of heat dissipation cavities 11 are formed between heat insulation component 1 9 and heat insulation component 2 10. Two sets of downward-sloping connecting pipes 22 are symmetrically installed on the condenser pipe 3 and the outlet pipe 21. The connecting pipes 22 extend into the heat dissipation cavity 11. Several condenser pipes 3 are longitudinally connected to the connecting pipes 22, and the several condenser pipes 3 are located in the heat dissipation cavity 11. A switching mechanism 4 is installed between the condenser pipe 3 and the connecting pipe 22. The switching mechanism 4 introduces the steam generated in the water storage tank 2 into different condenser pipes 3. Water storage tank 5, and several condenser pipes 3 are installed at the bottom of water storage tank 5; Two sets of dampers 6 are symmetrically installed on the outer side of the outer frame 1, and the dampers 6 are located at the front end of the heat dissipation cavity 11. Fan 8 is installed inside the heat dissipation cavity 11, and a switch for controlling fan 8 is installed inside the heat dissipation cavity 11. Thermal insulation component 314 is provided on the side of the outer frame 1 away from the water storage tank 2; The sealing plate 13 is installed inside the outer frame 1. The two sets of sealing plates 13 are located between the second heat insulation component 10 and the third heat insulation component 14.

[0023] In one embodiment, the first heat insulation component 9, the second heat insulation component 10, and the third heat insulation component 14 can all be autoclaved aerated concrete panels or heat insulation materials such as thermal insulation cotton; a vacuum layer is formed between the two sets of sealing plates 13, and the vacuum layer plays the role of heat insulation and sound insulation.

[0024] In practical application, when the ambient temperature rises, the temperature of the water storage tank 2 gradually increases, causing the water in the tank 2 to gradually evaporate. During evaporation, the water absorbs heat from the environment, leading to a decrease in the surrounding temperature and thus achieving a heat insulation effect. The generated steam enters the connecting pipe 22 through the vent pipe 21 and finally enters the metal condenser pipe 3. Upon contact with the metal condenser pipe 3, the steam liquefies and generates a large amount of latent heat. This heat is located within the heat dissipation cavity 11 and is absorbed through the insulation components 9, 10, the vacuum layer, and 14. The insulation effect prevents heat from entering the room. Two sets of dampers 6 allow air from the outside environment to enter through one set and exit through the other, thus carrying away heat from the heat dissipation cavity 11 and further preventing heat from entering the room, improving the insulation effect. If the outside temperature is high, resulting in a large amount of steam, the switch will control the fan 8 to start. The fan 8 will then expel the heat from the heat dissipation cavity 11 through the two sets of dampers 6, improving the heat dissipation effect and adjusting the insulation effect according to the outside temperature. In addition, if the temperature of one condenser tube 3 is too high, the switching mechanism 4 can introduce steam into another condenser tube 3, thereby improving the heat exchange efficiency and ensuring that the latent heat is dispersed in the heat dissipation cavity 11, so that the heat can be discharged from the heat dissipation cavity 11 in time, thereby improving the heat insulation effect; by intermittently delivering steam into different condenser tubes 3, the generated latent heat is evenly distributed in the heat dissipation cavity 11, avoiding heat accumulation and reducing the heat insulation effect. When the steam comes into contact with the condenser 3, it will liquefy. The high-temperature steam will change from a gaseous state to a low-temperature water. The water produced by liquefaction will eventually enter the water storage tank 5. Since the heat in the heat dissipation cavity 11 is continuously discharged, the water in the water storage tank 5 will not easily evaporate at this time. The water in the water storage tank 5 can flow back to the water storage tank 2, so that the water can be recycled and thus ensure the heat insulation effect.

[0025] Furthermore, a conduit 51 connects the water storage tank 5 and the water storage tank 2. The bottom of the water storage tank 5 is higher than the bottom of the water storage tank 2. Two sets of U-shaped plates 24 are symmetrically arranged on the inner wall of the water storage tank 2. A sealing plate 25 is slidably installed between the two sets of U-shaped plates 24. The sealing plate 25 is used to block the two sets of conduits 51. An elastic element 26 is connected between the sealing plate 25 and the bottom of the water storage tank 2. A vertical rod 27 is slidably installed inside the water storage tank 2. A float ball 28 floating on the water surface is provided at the bottom of the vertical rod 27. A guide pipe 23 is installed through the outer frame 1 and extends into the water storage tank 2.

[0026] In one embodiment, an inverted conical filter screen is provided at the top of the guide pipe 23, which can filter impurities in the rainwater.

[0027] In practical application, when the external environment is continuously hot, the water in the water storage tank 2 will be gradually consumed. The liquefied water is stored in the water storage tank 5. When the water in the water storage tank 2 is exhausted, the float 28 will gradually move down and squeeze the sealing plate 25. The sealing plate 25 will also move down, thereby releasing the blockage of the conduit 51. The water in the water storage tank 5 will then flow back to the water storage tank 2 through the conduit 51, ensuring that enough water is evaporated, thus ensuring the heat insulation effect and improving the service life of the assembled components. Of course, some water will be consumed during the evaporation and liquefaction process, which will cause the overall water volume to gradually decrease. At this time, when it rains in the external environment, the rainwater will enter the water storage tank 2 through the guide pipe 23, thus ensuring that enough water is evaporated to achieve the heat insulation effect.

[0028] Furthermore, one set of dampers 6 has several air outlets 61 that are inclined outward toward the heat dissipation cavity 11, and another set of dampers 6 has several sets of symmetrical flip plates 62 that are rotatably mounted on the other set of dampers 6. The opposite side of the two symmetrical flip plates 62 tends to be inclined inward toward the heat dissipation cavity 11, and a gap is formed between the two symmetrical flip plates 62. Filter screens are provided at the air outlets 61 and the gap formed between the two symmetrical flip plates 62, and a flow channel 12 is formed between the two sets of heat dissipation cavities 11.

[0029] The heat dissipation cavity 11 is equipped with an airbag 7. Both the surface of the airbag 7 and the cavity wall of the heat dissipation cavity 11 are equipped with an electric plate 71. The two sets of electric plates 71 form a switch to control the fan 8.

[0030] In one embodiment, a solar panel can be installed on the surface of the outer frame 1, and a battery and control unit can be installed inside the outer frame 1 to provide kinetic energy to the fan 8 through solar energy and the battery.

[0031] In practical application, when the ambient temperature is not too high, the latent heat generated after the steam liquefies will be in the heat dissipation cavity 11. Through the two sets of inward-turning flip plates 62, the wind from the outside environment will enter one of the heat dissipation cavities 11, then enter the other set of heat dissipation cavities 11 through the flow channel 12, and be discharged from the outward-turning air outlet 61. Thus, the heat in the heat dissipation cavity 11 is carried away and discharged by the wind from the outside environment, thereby cooling the heat dissipation cavity 11 and discharging the heat to the outside environment at the front end of the heat insulation component 2 10, thereby improving the heat insulation effect. When the outside temperature is high, the airbag 7 will absorb heat and gradually expand. The energized plate 71 on the airbag 7 will gradually come into contact with the energized plate 71 on the wall of the heat dissipation cavity 11. When the two sets of energized plates 71 come into contact, the control unit will control the fan 8 to rotate. The fan 8 will blow the hot air in the heat dissipation cavity 11 outward. At this time, the two sets of flip plates 62 will flip outward, which, together with the already outward-facing air vents 61, allows the hot air to be discharged smoothly, thereby adjusting the heat insulation effect in real time according to the outside temperature.

[0032] like Figures 1-8 As shown, the switching mechanism 4 includes an upper sliding plate 41, a first baffle 42, a second baffle 43, a first guide cylinder 44, and a locking element 45. The upper sliding plate 41 is longitudinally slidably mounted on the periphery of all condenser pipes 3 except those connected to the end of the connecting pipe 22. An elastic element 421 connects the upper sliding plate 41 to the connecting pipe 22. The upper sliding plate 41 has a first baffle 42. Several first annular plates 221 are located inside the connecting pipe 22 at the rear end of the connection between the connecting pipe 22 and the condenser pipe 3. The first baffle 42 extends through the connecting pipe 22 and blocks the first annular plates 221. The condenser pipe 3 has a second annular plate 31 inside, and a second baffle 43 is installed through the condenser pipe 3 to block the second annular plate 31. 1. The end of the baffle 2 43 is provided with an ear plate 432. An elastic element 3 431 is connected between the ear plate 432 and the condenser pipe 3. The upper slide plate 41 is provided with a wedge block 411. The end of the baffle 2 43 is rotatably mounted with a roller 433. The wedge block 411 and the roller 433 slide in cooperation. The outer periphery of the condenser pipe 3 is provided with a guide cylinder 1 44. An airbag 1 441 is installed in the guide cylinder 1 44. The bottom of the upper slide plate 41 is provided with a connecting plate 444. The bottom end of the connecting plate 444 is provided with a lower slide plate 443. The lower slide plate 443 is provided with a push rod 1 442. The push rod 1 442 extends into the guide cylinder 1 44 and abuts against the airbag 1 441. The locking element 45 is installed in the heat dissipation cavity 11. The locking element 45 is used to lock the upper slide plate 41.

[0033] The locking component 45 includes a base 451 and a locking block 452. The base 451 is fixed in the heat dissipation cavity 11 by a mounting plate 48. The locking block 452 is slidably mounted on the base 451. A guide rod 453 is provided on one side of the locking block 452. The guide rod 453 passes through the support at the end of the base 451. An elastic element 454 is sleeved around the guide rod 453. The locking block 452 is provided with a slanted groove 4521, a vertical groove 4522 and a horizontal groove 4523 from top to bottom. A fixing rod 412 is provided on the side of the upper slide plate 41. A magnetic plate 455 is provided on the side of the locking block 452. A magnetic block is provided at the bottom of the upper slide plate 41. The magnetic plate 455 and the magnetic block are attracted by magnetism.

[0034] In practical application, the generated steam enters the connecting pipe 22 and is blocked by the first set of baffles 42 near the outlet pipe 21. The steam then enters the first set of condenser pipes 3 near the outlet pipe 21. At this time, the second ring plate 31 is in the open state. As the steam continuously exchanges heat with the first set of condenser pipes 3, the first set of airbags 441 gradually expands, thereby pushing the push rod 442 downward. This causes the lower slide plate 443 and the connecting plate 444 to drive the upper slide plate 41 downward, causing the first set of baffles 42 to gradually move away from the first ring plate 221. At the same time, the wedge block 411 gradually squeezes the second baffle 43. Due to the roller 433, the second baffle 43 moves smoothly into the condenser pipe 3, thereby gradually blocking the second ring plate 31. During the downward movement of the upper slide plate 41, the cooperation of the magnetic plate 455 and the magnetic block enables the upper slide plate 41 to overcome the elastic force of the second elastic element 421 and move downward quickly, thereby realizing the rapid contact between the baffle 42 and the ring plate 221. Separation causes baffle 2 43 to quickly block ring 2 31. When the upper slide plate 41 moves down, the fixing rod 412 first squeezes the inclined groove 4521, thereby causing the locking block 452 to move. The fixing rod 412 will then enter the vertical groove 4522. When the fixing rod 412 crosses the vertical groove 4522, under the rebound action of the elastic element 454, the locking block 452 will quickly return to its original position. The fixing rod 412 is restricted by the horizontal groove 4523, so that the fixing rod 412 is in a fixed state at this time. That is, the baffle 1 42 and baffle 2 43 are in a fixed state at this time. The steam will continue to move along the connecting pipe 22 and enter the second set of condenser tubes 3. This process is repeated to allow the steam to enter different condenser tubes 3 intermittently, thereby ensuring the heat exchange effect of the condenser tubes 3, providing time for the condenser tubes 3 to cool down, and at the same time, ensuring that the latent heat generated after liquefaction is evenly distributed in the heat dissipation cavity 11, avoiding heat accumulation, and ensuring that the heat can be quickly discharged from the heat dissipation cavity 11, thereby improving the heat insulation effect. In addition, introducing steam into different condenser tubes 3 can enable rapid heat exchange of the steam. When the ambient temperature is high, a larger amount of steam is generated. This allows the steam to be switched into different condenser tubes 3, thereby enabling rapid heat exchange of the steam. The latent heat generated is evenly distributed and can be quickly discharged. This allows the insulation effect to be further adjusted according to the ambient temperature.

[0035] Furthermore, a guide cylinder 46 is provided around the condenser pipe 3 connected to the end of the connecting pipe 22. An airbag 461 is installed inside the guide cylinder 46. A push rod 462 is slidably installed through the end of the guide cylinder 46. One end of the push rod 462 abuts against the airbag 461, and the other end of the push rod 462 is equipped with several unlocking parts 47 for unlocking the upper slide plate 41.

[0036] The unlocking component 47 includes a push plate 471, which is fixed to the end of the push rod 462. The push plate 471 is provided with a pressing plate 472 and a shovel plate 473. The pressing plate 472 is used to press the locking block 452, and the shovel plate 473 is used to separate the magnetic block on the magnetic plate 455 and the upper slide plate 41. Two adjacent sets of unlocking components 47 are fixed together by a connecting rod.

[0037] In one embodiment, the shovel plate 473 is made of a non-magnetic material and is used to separate the magnetic plate 455 and the magnetic block.

[0038] In practical application, when steam enters the condenser 3 connected to the end of the connecting pipe 22, the second airbag 461 will gradually expand and squeeze the second push rod 462. The second push rod 462 will drive several unlocking parts 47 to move towards the locking part 45. The squeezing plate 472 will squeeze the locking block 452. The shovel plate 473 will be inserted between the magnetic plate 455 and the magnetic block to separate them. After the locking block 452 is squeezed, the fixing rod 412 gradually overlaps with the vertical groove 4522. Under the rebound action of the second elastic part 421, the upper slide plate 41 quickly returns to its original position. Under the rebound action of the third elastic part 431, the first baffle 42 and the second baffle 43 quickly return to their original positions. That is, the first baffle 42 blocks the first ring plate 221, and the second baffle 43 moves away from the second ring plate 31. In this way, the steam will re-enter the first set of condenser 3. At this time, the condenser 3 has been cooled. This cycle is repeated to ensure the heat exchange efficiency of the condenser 3.

[0039] Working principle: When the outside temperature rises, the temperature of the water storage tank 2 gradually increases, causing the water in the tank 2 to gradually evaporate. During evaporation, the water absorbs heat from the environment, leading to a decrease in the surrounding temperature, thus achieving a heat insulation effect. The generated steam enters the connecting pipe 22 through the vent pipe 21, and finally enters the metal condenser pipe 3. Upon contact with the metal condenser pipe 3, the steam liquefies, generating a large amount of latent heat. This heat is located in the heat dissipation cavity 11 and passes through two sets of dampers 6, allowing air from the outside environment to enter through one set of dampers 6. Then the heat is discharged from another set of dampers 6, thus carrying away the heat inside the heat dissipation cavity 11 to the outside environment. If the outside temperature is high, resulting in a large amount of steam, the switch will control the fan 8 to start. The fan 8 can discharge the heat inside the heat dissipation cavity 11 from the two sets of dampers 6 respectively. In addition, if the temperature of one condenser tube 3 is too high, the switching mechanism 4 can introduce steam into another condenser tube 3, thereby improving the heat exchange efficiency, ensuring that the latent heat is dispersed in the heat dissipation cavity 11, and thus ensuring that the heat can be discharged from the heat dissipation cavity 11 in time, thereby improving the heat insulation effect.
