[0002] Metal composite insulation board is a kind of insulation material and is a prefabricated board. During the construction of prefabricated boards, the installation work can be completed after splicing and fixing. In addition, due to its excellent thermal insulation performance, metal composite insulation boards can be used on the roof when cold chain warehouses are being built.

[0003] Although metal composite insulation boards have high strength and good corrosion resistance, they will inevitably be damaged as the use time increases. When metal composite insulation boards are used in cold chain warehouses, if the surface of the metal composite insulation boards is damaged and the internal moisture is high, it will not only affect its insulation performance, but also accelerate the corrosion of its internal supporting structure. The cold chain warehouse cannot be stopped at will during use. Therefore, it is particularly important to detect the status of the composite insulation boards in order to transfer the goods inside the cold chain warehouse in advance.

DETAILED DESCRIPTION

[0016] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. 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.

[0017] The present invention provides a metal composite insulation board roof structure through improvement. The technical solution of the present invention is: like Figure 1 - Fig.10 As shown, a metal composite insulation board roof structure comprises: A first thermal insulation layer 104, a shell 101 is disposed on the top and bottom of the first thermal insulation layer 104, a support plate 202 is disposed on the top and bottom of the first thermal insulation layer 104, and the two support plates 202 are respectively located in the two shells 101, a first fixing component and a plurality of second fixing components are respectively disposed on the two support plates 202, a sponge layer 106 and a waterproof layer 107 are sequentially disposed on the top of the upper support plate 202 from bottom to top, and the waterproof layer 107 is fixed to the inner wall of the upper shell 101; The boss 301 is fixed to the top of the housing 101, and the boss 301 is a hollow structure; A guide component is disposed in the convex seat 301 and in contact with the sponge layer 106 , and is used to absorb moisture in the sponge layer 106 ; A heating component is disposed in the convex seat 301 and above the guide component, and is used to heat the guide component to vaporize the water in the guide component; The heat conduction component is arranged in the boss 301 and is used to transfer the heat in the guide component.

[0018] When the surface of the composite insulation board is intact, rainwater cannot enter the composite insulation board. At this time, the moisture content in the composite insulation board is low or in a dry state. When the surface of the composite insulation board is severely damaged, rainwater enters the composite insulation board through the damaged area. At this time, the water content in the composite insulation board is high. By heating the water vapor in the guide component and transferring the heat of the water vapor to the bottom surface of the composite insulation board (the side indoors) through the heat conduction component, it is possible to manually perform inspection of the composite insulation board in the cold chain warehouse. When there is less or no water vapor, the heat conduction component receives less heat, which makes the temperature of the part of the heat conduction component in the cold chain warehouse lower, which means that the composite insulation board is in good condition. When there is more water vapor, the temperature of the part of the heat conduction component in the cold chain warehouse is higher, which means that the water content inside the composite insulation board is higher, that is, the composite insulation board is seriously damaged and can be replaced.

[0019] Furthermore, the boot component includes: The tube body 501 is fixed on the inner wall of the bottom of the convex seat 301, and the bottom end of the tube body 501 passes through the bottom of the convex seat 301, the inner wall of the housing 101 above and the waterproof layer 107 in sequence, and the bottom end of the tube body 501 contacts the sponge layer 106; The cotton core 504 is filled in the tube body 501 (such as Figure 7 As shown), the cotton core 504 is in contact with the sponge layer 106; A heat-insulating seat 502 is fixed on the top of the tube body 501. A metal plate 503 is fixed on the top of the heat-insulating seat 502. The surface of the metal plate 503 is coated with a heat-absorbing coating. Multiple heat-conducting components are fixed to the bottom of the metal plate 503 , and each heat-conducting component is deeply inserted into the cotton core 504 .

[0020] Since the cotton core 504 and the sponge layer 106 are in contact, when the sponge layer 106 contains a large amount of water, the top of the cotton core 504 is also in a wet state through the adsorption of water by the cotton core 504 and the capillary action.

[0021] Furthermore, the heat conducting component includes: Copper tube 505, the top of copper tube 505 is fixed to metal plate 503, the bottom of copper tube 505 is in cotton core 504, and both ends of copper tube 505 are sealed structures; The wick 508 is fixed on the inner wall of the copper tube 505 (such as Figure 8 As shown in FIG. 5 ), the wick 508 is a tubular structure, and both ends of the wick 508 are open structures. The copper tube 505 is in a normal pressure environment, and the copper tube 505 is filled with pure water.

[0022] The normal pressure state in the copper tube 505 and the evaporation of pure water make the temperature of the contact position between the copper tube 505 and the cotton core 504 about 100 degrees Celsius, thus preventing the cotton core 504 from being overheated and catching fire. It is worth noting that the amount of pure water in the copper tube 505 is sufficient to keep the wick 508 in a wet state, that is, the amount of pure water in the copper tube 505 should be small to ensure the speed of temperature transfer.

[0023] Further, the heating component comprises: Convex lens 305, convex lens 305 is arranged above the heat insulation seat 502, a bracket 304 is fixed to the side wall of the convex lens 305, and the bracket 304 is fixed to the inner wall of the convex seat 301; Rectangular hole, the rectangular hole is opened on the top of the boss 301, and the rectangular hole is above the convex lens 305, the first heat conducting plates 306 are fixed on the two inner walls of the rectangular hole, the glass 302 is fixed between the two first heat conducting plates 306, a plurality of heating wires 303 are embedded in the glass 302, and the heating wires 303 are in contact with the first heat conducting plates 306, a second heat conducting plate 307 is fixed at the bottom of the first heat conducting plate 306, the second heat conducting plate 307 is an L-shaped structure, and the second heat conducting plate 307 is in contact with the metal plate 503.

[0024] In rainy and snowy weather, the rain and snow on the surface of the glass 302 can be quickly evaporated through the operation of the electric heating wire 303, thereby ensuring that the light transmittance of the glass 302 can be quickly restored after the rainy and snowy weather, thereby ensuring the heating effect of the convex lens 305, so that the water content in the composite board can be immediately detected after the rainy and snowy weather; If the weather at the location of the cold chain warehouse is "rainy and cloudy", the switch of the heating wire 303 can be manually turned on when the status of the metal composite insulation board is detected. When the heating wire 303 is working, the heat generated by the heating wire 303 is transferred to the metal plate 503 through the first heat conducting plate 306 and the second heat conducting plate 307, thereby heating the end of the copper tube 505, and then the status of the metal composite insulation board can be detected under poor weather conditions.

[0025] Furthermore, the heat conduction component includes: The cover body 403 is fixed on the inner wall of the bottom of the protruding seat 301; The heat pipe 402 is fixed on the inner wall of the bottom of the boss 301, and the top of the heat pipe 402 is in the cover 403, and the bottom of the heat pipe 402 passes through the bottom of the shell 101 below; The heat insulation board 401 is fixed on the bottom of the housing 101 below (such as Figure 2 As shown), the heat insulation board 401 and the heat pipe 402 are fixed, a heat conduction block 404 is provided through the bottom of the heat insulation board 401, and the heat conduction block 404 and the bottom end of the heat pipe 402 are in conflict; The connecting pipe 507 has two ends connected with the cover body 403 and the pipe body 501 respectively, and the connecting pipe 507 is sleeved with a heat preservation pipe 506 .

[0026] Since one end of the heat pipe 402 is in the cold chain warehouse and the other end is in the cover 403, when water vapor enters the cover 403, the heat carried by the water vapor is transferred to the cold chain warehouse by the heat pipe 402, which facilitates the detection work; In addition, when the amount of water vapor is small (i.e., the water content in the composite insulation board is small), the water vapor condenses at the end of the heat pipe 402 and is stored in the cover 403, thereby achieving a drying process for the sponge layer 106, thereby avoiding the support plate 202 from being in a humid environment for a long time, thereby ensuring the strength of the composite insulation board.

[0027] Further, the first fixing component includes: A plurality of fixing ear plates 201 are fixed on four sides of the top of the support plate 202 above, and each fixing ear plate 201 passes through the top of the shell 101 above, and each fixing ear plate 201 is provided with a fixing hole.

[0028] Further, the second fixing assembly includes: Two fixing rods 203, both fixing rods 203 are fixed to the support plate 202 at the bottom, and both fixing rods 203 pass through the bottom of the housing 101 at the bottom; The clamp 204 is fixed by a nut and two fixing rods 203 .

[0029] By fixing the ear plates 201, the fixing work between two adjacent composite insulation boards is achieved, and the composite insulation board and the cold chain warehouse roof truss are fixed by the fixing rod 203 and the clamp 204. In this way, when one of the composite insulation boards on the roof of the cold chain warehouse is damaged, it can be replaced in a targeted manner to avoid replacing the entire roof, thereby reducing the workload and the downtime of the cold chain warehouse.

[0030] Furthermore, the second rubber plates 103 are fixed to two side walls of the first insulation layer 104, the first rubber plates 102 are fixed to the other two side walls of the first insulation layer 104, the second insulation layer 105 is fixed in the shell 101 below, and the second insulation layer 105 is fixed to the nearest support plate 202.

[0031] Working principle: During the laying stage, the composite insulation board is placed on the truss of the roof of the cold chain warehouse, and the truss is placed between the two fixing rods 203. The clamp 204 and the fixing rod 203 are fixed with nuts to complete the fixation between the composite insulation board and the truss. The composite insulation board is installed in sequence, and then the adjacent composite insulation boards are fixed by fasteners and the fixing holes on the fixing ear plates 201. After the adjacent composite insulation boards are fixed, the first rubber sheet 102 and the second rubber sheet 103 are used to make the two adjacent composite insulation boards in close contact to ensure the waterproof performance of the composite insulation board roof. Finally, the joints are waterproofed again and the insulation materials are fixed to complete the laying of the composite insulation board. After the composite insulation board is laid, a temperature sensor can be installed on the insulation board 401, and the temperature of the heat-conducting block 404 on the insulation board 401 can be detected by the temperature sensor. A manual handheld infrared thermometer can also be used to measure the temperature of the heat-conducting block 404. During manual measurement, a larger area of ​​the insulation board 401 can facilitate manual discovery of the measurement point, so as to facilitate the measurement work; During use, if the surface of the composite insulation board is corroded and damaged, rainwater enters the composite insulation board through the damaged part. When the composite insulation board is seriously flooded, the sponge layer 106 absorbs the moisture in the composite insulation board. Therefore, the absorption of the sponge layer 106 can temporarily maintain the insulation performance of the composite insulation board and reduce the corrosion rate of the support plate 202 to a certain extent. Through the absorption of water by the cotton core 504 and the capillary action, the water in the sponge layer 106 enters the cotton core 504, so that the cotton core 504 is also in a wet state; On a sunny day, sunlight shines through the glass 302 onto the convex lens 305. The convex lens 305 focuses the light and the heat-absorbing coating on the metal disk 503 causes the metal disk 503 to be at a relatively high temperature, thereby heating the copper tube 505. After the contact position between the copper tube 505 and the metal disk 503 is heated, the pure water in the copper tube 505 is heated. Since the copper tube 505 is at normal pressure, the pure water in the copper tube 505 is heated to boiling and generates water vapor. The water vapor moves to the bottom of the copper tube 505 and liquefies, releasing heat to heat the water in the cotton core 504. Since the copper tube 505 is at normal pressure, the temperature of the contact portion between the copper tube 505 and the cotton core 504 is controlled at about 100 degrees Celsius to prevent the cotton core 504 from being overheated and causing a fire. As the moisture in the cotton core 504 is continuously heated, steam is continuously generated, so that the air pressure in the tube body 501 is continuously increased, and then the water vapor enters the cover body 403 through the connecting pipe 507, and heats the end of the heat pipe 402. The heat conduction of the heat pipe 402 causes the temperature of the bottom end of the heat pipe 402 to rise, and then heats the heat conducting block 404 on the heat insulation board 401. Through the blocking of the heat insulation board 401 and the small heat conducting block 404, the heat exchange speed between the heat pipe 402 and the inside of the cold chain warehouse is slow, and the heat exchange is less, so as to avoid affecting the temperature in the cold chain warehouse; In summary, when the sponge layer 106 has less moisture or is in a dry state (i.e., when the housing 101 is not damaged), the cotton core 504 has less moisture or is in a dry state. At this time, due to the heat conduction of the copper tube 505, the air temperature in the tube body 501 rises. However, since air is a poor conductor of heat, the heat is not enough to be transferred to the cover body 403 through the air in the connecting tube 507. At this time, the temperature at the bottom of the heat pipe 402 will not change significantly, thereby avoiding affecting the temperature in the cold chain warehouse. When the water content in the sponge layer 106 is high but within the design range (i.e., the damage state of the shell 101 is within a reasonable range), a small amount of water vapor enters the cover body 403 through the connecting pipe 507, condenses on the surface of the heat pipe 402, and liquid water is stored in the cover body 403, so as to achieve a certain degree of drying of the sponge layer 106, thereby reducing the water content in the sponge layer 106, thereby preventing the water from contacting the support plate 202 for a long time, causing the support plate 202 to be in a humid environment for a long time, thereby reducing the degree of corrosion of the support plate 202; When the moisture in the sponge layer 106 exceeds the design range (i.e., when the shell 101 is seriously damaged), a large amount of water vapor enters the cover body 403, so that the heat-conducting block 404 on the heat-insulating board 401 is at a high temperature. At this time, the composite insulation board can be replaced. Since the composite insulation board is fixed to each other through the fixing ear plate 201, and the composite insulation board and the roof truss are fixed through the fixing rod 203 and the clamp 204, the damaged composite insulation board can be replaced separately to reduce the workload of replacing the composite insulation board roof, thereby reducing the downtime of the cold chain warehouse; Therefore, during the cold chain warehouse commissioning stage, under sunny weather conditions, the staff can use a handheld infrared temperature sensor to measure the temperature of the heat conductive block 404 in the cold chain warehouse. If the temperature of the heat conductive block 404 is within a reasonable range, it means that the composite insulation board has normal insulation performance. If the temperature of the heat conductive block 404 is high, it means that the water content in the composite insulation board is too high, that is, the composite insulation board is seriously damaged. It is worth mentioning that even if the composite insulation board is severely damaged before the rainy weather, and the rain causes the water content in the composite insulation board to be high, the insulation effect provided by the second insulation layer 105 can still meet the needs of the cold chain warehouse for a long time. The sponge layer 106 adsorbs water to reduce the degree of corrosion of the support plate 202, and can still provide sufficient support capacity for the composite insulation board.
