Description

Technical Field

[0001] The invention relates to a radiation hollow plate, in particular to a graphene radiation hollow plate, and belongs to the technical field of internal radiation heat exchange. Background Art

[0002] The radiation hollow board can transfer heat by thermal radiation. Thermal radiation is the phenomenon that an object emits electromagnetic radiation due to its own temperature. Its energy transfer does not require the help of a medium and can be carried out in a vacuum. When the surface temperature of the radiation hollow board is higher than the ambient temperature, it will emit thermal radiation to the surrounding environment to dissipate the heat; conversely, when the surface temperature is lower than the ambient temperature, it will also absorb the thermal radiation of the surrounding environment to obtain heat. Graphene has super high thermal conductivity and can conduct heat quickly. After adding graphene to the hollow board, the board can dissipate heat more efficiently when it is subjected to heat, avoiding local overheating. During the installation of the hollow board, it is necessary to install the keel without the top and then fix it with bolts.

[0003] At present, during the installation of hollow panels, due to the construction process or the material itself, there may be a certain height difference between adjacent hollow panels after they are fixed. It is inconvenient to adjust the height of the hollow panels during installation, which not only affects the beauty of the assembly, but also affects the fitting effect between adjacent panels. In addition, during the rainy season in the south, the air humidity is often very high, and there is a high risk of condensation at the bottom of the radiation panel, which will cause the screws to rust and affect the stability of the installation.

[0004] For this purpose, a graphene radiation hollow plate is designed to optimize the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide a graphene radiation hollow plate, which has an installation height fine-tuning structure composed of a sliding hole, an internal thread block, a limit groove, a trapezoidal plug block, a positioning spring, and an annular slot arranged at the screw installation position under the thermal insulation bottom plate. During the installation process, after the plate to be installed is leveled with the bottom of the side plate, the internal thread block is first pushed by the screw to fill the gap between the plate and the keel, and then the screw is rotated to fix the plate for installation, thereby ensuring the level and beauty of the plate, and having higher practicality. An outer sleeve, an inner through pipe, an annular piston, an extrusion sleeve, an annular sheet, an annular air groove, an elastic membrane are arranged at the installation position of the screw on the decorative panel. The screw sealing protection mechanism can automatically squeeze the annular piston toward the end of the outer sleeve through the screw during the installation and fixing process, and fill the gas between the outer sleeve and the inner tube into the annular air groove to control the expansion and bulging of the elastic membrane. After the installation tool is separated from the screw, a sealing protection is automatically formed on the top of the screw, effectively avoiding rust of the screw due to condensation. By arranging grooves and hollow sealing strips on the side of the insulation base plate, and then cooperating with the air cavity at the corners of the insulation board, the circular piston, the inner screw tube, the limit ring and the installation groove at the corners of the decorative panel, and the sealing bolt to form a plate sealing mechanism, the sealing tightness between adjacent hollow panels can be improved.

DETAILED DESCRIPTION

[0030] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0031] like Figure 1-Figure 8 As shown, the present embodiment provides a graphene radiation hollow plate, comprising a thermal insulation base plate 1, a conduction pipeline 7 installed on the top of the thermal insulation base plate 1, a lower graphene plate 6 and an upper graphene plate 8 respectively located at the top and bottom of the conduction pipeline 7 to limit the conduction pipeline 7, and a decorative panel 9 fixed on the outer surface of the upper graphene plate 8, the outer side of the thermal insulation base plate 1 is provided with a plate sealing mechanism 2 for sealing the gap between adjacent plates, the bottom of the thermal insulation base plate 1 is provided with an installation height fine-tuning structure 5 at the corresponding screw installation position, a hollow partition plate 3 is arranged between the top of the thermal insulation base plate 1 and the lower graphene plate 6, the interior of the hollow partition plate 3 is filled with inert gas 4, and the position of the hollow partition plate 3 corresponding to the installation height fine-tuning structure 5 is provided with a storage through pipe 28, the bottom of the decorative panel 9 is provided with a screw sealing protection mechanism 10 at the corresponding screw installation position, and the lower graphene plate 6 and the upper graphene plate 8 are provided with through holes 11 cooperating with the screw sealing protection mechanism 10.

[0032] The overall working principle: during the installation of the radiation hollow panel, first install the keel on the roof, then fit the thermal insulation base plate 1 on the keel, use screws to pass through the inside of the screw sealing protection mechanism 10, then pass through the storage through pipe 28 and the installation height fine-tuning structure 5, and finally fix the screws on the keel. If there is unevenness between adjacent radiation hollow panels during the installation process, the installation height fine-tuning structure 5 can be used to raise the insulation base plate 1 and the keel to ensure that the adjacent radiation hollow panels are level. After the screws are fixed, the screw sealing protection mechanism 10 will seal the end of the screw to avoid rusting of the screw. In addition, after all the radiation hollow panels are installed, the plate sealing mechanism 2 is used to seal the gaps between the plates.

[0033] In this embodiment, the installation height fine-tuning structure 5 includes a sliding hole 31, an internal thread block 32 and a locking assembly. The sliding holes 31 are evenly arranged at the bottom of the thermal insulation base plate 1. The internal thread blocks 32 are vertically slidably arranged inside the sliding holes 31. The side of the sliding hole 31 is provided with a locking assembly for fixing the position of the internal thread block 32.

[0034] Local working principle: During the installation process, when the screw is inserted into the interior of the radiation hollow panel and contacts the internal thread block 32, if there is a gap between the radiation hollow panel and the keel, an upward thrust is applied to the internal thread block 32 to push the internal thread block 32 upward. After the internal thread block 32 is fitted with the keel, the position of the internal thread block 32 is limited by the locking assembly, and then the screw is rotated. The screw passes through the interior of the internal thread block 32 and enters the keel to fix the radiation hollow panel.

[0035] In this embodiment, the locking assembly includes a limit groove 33, an annular slot 36, a positioning spring 35 and an annular slot 36. The limit groove 33 is opened at the bottom of the inner side of the sliding hole 31. A trapezoidal plug block 34 is slidably installed inside the limit groove 33. A positioning spring 35 is arranged between the trapezoidal plug block 34 and the inner end of the limit groove 33. An annular slot 36 cooperating with the trapezoidal plug block 34 is opened on the outer side edge of the internal thread block 32.

[0036] Local working principle: after the screw applies an upward thrust to the internal thread block 32, the internal thread block 32 will apply pressure to the hypotenuse of the trapezoidal plug block 34, squeezing the trapezoidal plug block 34 into the inside of the limit groove 33, and then the internal thread block 32 slides to fit between the keels. After the position of the internal thread block 32 is fixed, the positioning spring 35 applies a thrust to insert the trapezoidal plug block 34 into the inside of the annular slot 36 to fix the position of the internal thread block 32. The upward spacing of the internal thread block 32 is affected by the spacing of the annular slots 36. By adjusting the spacing of the annular slots 36, the rising accuracy of the internal thread block 32 can be improved.

[0037] In this embodiment, an annular sealing ring 37 is fixedly disposed at the bottom of the internal thread block 32 , and the inner diameter of the annular sealing ring 37 is larger than the inner ring radius of the internal thread block 32 .

[0038] Partial working principle: During the fixing process, the annular sealing ring 37 will be squeezed between the internal thread block 32 and the keel, and the annular sealing ring 37 can be used to seal the bottom end of the screw.

[0039] In this embodiment, plastic films 29 are provided on the top and bottom of the storage tube 28 , and the interior of the storage tube 28 is filled with desiccant powder 30 .

[0040] Partial working principle: During the installation of the screw, the desiccant powder 30 passes through the inner part of the internal thread block 32 and punctures the plastic film 29. When used on the outer side of the screw, it has a certain moisture absorption effect, effectively preventing the screw from rusting.

[0041] In this embodiment, the screw sealing protection mechanism 10 includes an outer sleeve 21, an annular air groove 26, an elastic membrane 27 and an inflation component. The outer sleeve 21 is vertically fixed on the decorative panel 9, and the outer sleeve 21 passes through the decorative panel 9. An annular air groove 26 is provided at the top end of the inner side of the outer sleeve 21, and an elastic membrane 27 is provided between the inner top and inner bottom of the annular air groove 26. An inflation component for supplying air to the inside of the annular air groove 26 is provided inside the outer sleeve 21.

[0042] Local working principle: During the installation of the screw, it is inserted from the inside of the outer sleeve 21, and during the process of insertion and fixing, the inflation component is controlled to inflate the inside of a pair of annular air grooves 26, and the elastic membrane 27 expands and bulges. After the installation is completed, the end of the screw is sealed.

[0043] In this embodiment, the inflation component 1 includes an inner tube 22, an annular piston 23, an extrusion sleeve 24 and an annular sheet 25. The inner tube 22 is fixed to the inner bottom of the outer sleeve 21, and a gap is left between the outer sleeve 21 and the inner tube 22. An annular piston 23 is installed on the outer side of the inner tube 22. The outer side of the annular piston 23 is in contact with the inner wall of the outer sleeve 21. The inner bottom end of the outer sleeve 21 is connected to the inside of the annular air groove 26. The top of the annular piston 23 is fixed with an extrusion sleeve 24, and the top of the extrusion sleeve 24 is fixed with an annular sheet 25.

[0044] Local working principle: When the screw is installed, it passes through the annular sheet 25 and squeezes the annular sheet 25. When the annular sheet 25 is under pressure, it applies pressure to the annular piston 23 through the extrusion sleeve 24. The annular piston 23 moves toward the end of the outer sleeve 21, squeezing the gas between the outer sleeve 21 and the inner tube 22 into the inside of the annular gas groove 26.

[0045] In this embodiment, the inner top of the outer sleeve 21 is evenly provided with sealing valves 12 along the circumferential direction. The sealing valves 12 are fan-shaped, and the ends and sides of the sealing valves 12 are in contact with each other.

[0046] Partial working principle: After installation, the sealing valve 12 can apply another layer of protection to the end of the outer sleeve 21 to improve the sealing effect.

[0047] In this embodiment, the plate sealing mechanism 2 includes a groove 13, a hollow sealing strip 14 and two inflatable components. The groove 13 is opened along the side direction of the thermal insulation base plate 1, and the interior of the groove 13 is provided with a hollow sealing strip 14 along the length direction. The corners of the thermal insulation base plate 1 are provided with two inflatable components for supplying air to the inside of the hollow sealing strip 14.

[0048] Local working principle: After the radiation hollow panel is installed, the inside of the hollow sealing strip 14 is inflated by using two air supply components. Each group of two air supply components corresponds to one group of hollow sealing strips 14. The relative hollow sealing strips 14 on the two groups of radiation hollow panels expand and fit together to ensure the sealing performance between the radiation hollow panels.

[0049] In this embodiment, the second inflation component includes an air cavity 15, a circular piston 16, an inner screw tube 17, a limiting ring 18, an installation groove 19 and a sealing bolt 20. The air cavity 15 is opened at the four corners of the top of the thermal insulation base plate 1, and the air cavity 15 is respectively connected with the hollow sealing strip 14. The inside of the air cavity 15 is vertically slidably installed with a circular piston 16, and the top of the circular piston 16 is vertically fixed with an inner screw tube 17. The outer side of the inner screw tube 17 is sleeved with a limiting ring 18, and the limiting ring 18 is fixed to the inside of the air cavity 15. The four corners of the thermal insulation base plate 1 are provided with installation grooves 19, and the inside of the installation grooves 19 is rotatably installed with sealing bolts 20. The bottom end of the sealing bolt 20 is inserted into the inside of the inner screw tube 17 and is threadedly connected to the inner screw tube 17.

[0050] Local working principle: When the hollow sealing strip 14 is inflated, the sealing bolt 20 is rotated. Since the inner screw tube 17 is limited by the limiting ring 18, the sealing bolt 20 can only drive the inner screw tube 17 to move vertically, driving the circular piston 16 to slide inside the air cavity 15, and squeezing the gas inside the air cavity 15 into the inside of the hollow sealing strip 14.

[0051] The above description is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
