Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided in order to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

Referring to Figures 1 to 5 and Figures 10 to 11, the embodiment of the present invention provides a flexible roof support unit, including: a support 10 and a magnetic metal mesh layer 12; the support 10 includes: 10 on the waterproof coiled material layer 11, the waterproof coiled material layer 11 is provided with a magnetic metal mesh layer 12 on the side facing the flexible roof 20; Connected with the photovoltaic module; the magnetic metal mesh layer 12 is provided with a plurality of holes; the flexible roof 20 is provided with installation holes 201, and the support 10 is fixed on the flexible roof 20 through the installation holes 201; in the case of heating the magnetic metal mesh layer 12 In one embodiment, the side of the waterproof coiled material layer 11 facing the flexible roof 20 is melted, and is thermally fused and fixed to the flexible roof 20 through the holes of the magnetic metal mesh layer 12 .

Specifically, as shown in Figures 1 to 5 and Figures 10 to 11, when installing the flexible roof support unit, the support 10 is inserted into the installation hole 201 of the flexible roof 20, so that the magnetic metal mesh layer 12 and the flexible roof 20 Contact, and then the staff uses the electromagnetic welding machine to make the electromagnetic welding torch 30 contact with the waterproof coiled material layer 11, and then connect the main machine of the welding machine to the power supply, the heating structure in the electromagnetic welding torch 30 generates a magnetic field through the current delivered by the main machine of the welding machine, and the magnetic metal The temperature of the mesh layer 12 continues to rise under the action of the magnetic field. When a certain temperature is reached, the side of the waterproof coiled material layer 11 and the flexible roof 20 in contact with the magnetic metal mesh layer 12 will melt into a fluid due to high temperature, and then the fluid can pass through the magnetic field. The holes of the metal mesh layer 12 are in contact with each other; further, the staff can make the heat dissipation plate 401 of the pressing part 40 contact with the waterproof coiled material layer 11, and press the waterproof coiled material layer 11 on the flexible roof 20, and then the flexible roof 20. The temperature of the magnetic metal mesh layer 12 and the waterproof membrane layer 11 can be transmitted through the heat dissipation plate 401 of the pressing part 40 and a plurality of heat dissipation columns 402 to achieve the effect of rapid cooling, so that the flexible roof 20 and the waterproof membrane layer 11 The molten contact positions are cooled and solidified together to form a molten column. In this way, the waterproof coiled material layer 11 is connected to the flexible roof 20 through a plurality of molten columns, so as to achieve the effect of welding the flexible roof 20 and the waterproof coiled material layer 11 together. The method of heating the magnetic metal mesh layer 12 by electromagnetic welding can effectively avoid the damage of the membrane caused by direct heating of the waterproof membrane and affect the installation stability and aesthetics.

In the embodiment of the utility model, the staff can press the electromagnetic welding torch 30 when heating the magnetic metal mesh layer 12, so that the contact between the flexible roof 20 and the waterproof coiled material layer 11 and the magnetic metal mesh layer 12 is more sufficient, and then can be faster The flexible roof 20 and the waterproof membrane layer 11 are fused. For the welding method that does not use the magnetic metal mesh layer 12, the hot air welding technology needs to blow hot air between the flexible roof 20 and the waterproof coiled material layer 11, and then perform rolling to make the waterproof coiled material layer 11 and the flexible roof 20 fully contact and fixed on the At the same time, the operation of the welding process is complicated. For factors such as hot air heating time and radiation range, it is easily affected by human factors and environmental factors, resulting in unsatisfactory welding results and different welding firmness of different parts; and heat conduction technology requires work. Personnel use a tool to touch the side of the waterproof coiled material layer 11 facing away from the flexible roof 20 for heating, thereby causing the side of the waterproof coiled material layer 11 facing the flexible roof 20 to melt, thereby realizing welding, but because the thermal coefficient of the waterproof coiled material layer 11 is low Low, higher temperature is required to weld the waterproof membrane layer 11 and the flexible roof 20 together. At this time, the side of the waterproof membrane layer 11 facing away from the flexible roof 20 may have been damaged due to high temperature, which will affect the appearance and service life. , and if the waterproof coiled material layer 11 is directly heated for the side in contact with the flexible roof 20, it will increase the difficulty of welding operation, thereby affecting the quality of welding. However, in the embodiment of the present application, by adding a magnetic metal mesh layer 12 and adopting the heating mode of the electromagnetic welding torch 30, the staff only needs to make the electromagnetic welding torch 30 contact the waterproof coiled material layer 11 to realize heating, and the welding machine host can be set. The output power can be precisely controlled to the temperature to which the magnetic metal mesh layer 12 needs to be heated to ensure uniform welding, convenient operation, and the magnetic metal mesh layer 12 can quickly reach the expected temperature, and the welding efficiency is greatly improved.

Optionally, usually the flexible roof 20 and the waterproof membrane layer 11 can adopt polymer waterproof membranes, and optionally, the polymer waterproof membranes can adopt EPDM (Ethylene Propylene Diene Monomer, EPDM), PVC (Polyvinyl chloride, polyvinyl chloride), TPO (Thermoplastic polyolefin, thermoplastic polyolefin) and other materials.

Optionally, as shown in FIG. 6 , the magnetic metal mesh layer 12 is circular, and the magnetic metal mesh layer 12 includes a magnetic metal mesh 121 and a first magnetic metal ring 122; the first magnetic metal ring 122 is along the edge of the magnetic metal mesh 121 set up.

Specifically, as shown in Figure 6, the magnetic metal mesh layer 12 can adopt a circular shape, and when the material of the selected magnetic metal mesh layer 12 does not have anti-corrosion properties, it is necessary to make the magnetic metal mesh layer 12 Anti-corrosion design.

Specifically, the magnetic metal mesh layer 12 may include a magnetic metal mesh 121 and a first magnetic metal ring 122. The first magnetic metal ring 122 is arranged on the outer edge of the magnetic metal mesh 121. Due to the setting of the first magnetic metal ring 122, the magnetic metal The edge of the mesh layer 12 forms a circle of uniform ring-shaped molten columns that completely isolate the magnetic metal mesh layer 12 from the outside world, thereby effectively isolating the contact between the outside water vapor and the magnetic metal mesh layer 12, and preventing the magnetic metal mesh layer 12 from Corrosion, thereby increasing the service life of the flexible roof support unit.

In addition, by heating the first magnetic metal ring 122, the connection between the waterproof coiled material layer 11 and the flexible roof 20 at the edge of the magnetic metal mesh layer 12 is more uniform and stable, and the uneven distribution of wire ends at the edge of the magnetic metal mesh 121 is avoided from causing waterproofing. The connection between the coiled material layer 11 and the flexible roof 20 is not uniform, and the problem of tearing easily occurs.

Optionally, as shown in FIG. 7 , the magnetic metal mesh layer 12 also includes at least one isolated magnetic metal ring 123; at least one isolated magnetic metal ring 123 is arranged on the periphery of the first magnetic metal ring 122, along the distance away from the first magnetic metal ring 122, the radius of at least one isolated magnetic metal ring 123 increases sequentially; the isolated magnetic metal ring 123 adjacent to the first magnetic metal ring 122 is connected to the first magnetic metal ring 122 through a plurality of connectors 124, and the adjacent The two isolated magnetic metal rings 123 are connected by a plurality of connecting pieces 124 .

Specifically, as shown in FIG. 7, in order to further improve the corrosion resistance of the magnetic metal mesh layer 12 in the flexible roof support unit, on the basis of the first magnetic metal ring 122, the outer periphery of the first magnetic metal ring 122 can be further At least one isolated magnetic metal ring 123 is provided, and the radii of these isolated magnetic metal rings 123 increase sequentially along the direction away from the first magnetic metal ring 122, and the first magnetic metal ring 122 is connected to an adjacent isolated magnetic metal ring 123 through a plurality of 124, and two adjacent isolated magnetic metal rings 123 are connected through a plurality of connecting pieces 124, so as to block the transmission of corrosion through the connecting pieces. Optionally, in order to achieve the effect of blocking corrosion transmission, the connecting piece 124 can be made of plastic material, or other materials that can achieve the above-mentioned effect, so that when the magnetic metal mesh layer 12 is heated, the connecting piece 124 is isolated from the magnetic When the metal ring 123 or the first magnetic metal ring 122 is connected, the temperature will increase accordingly, which will cause the flexible roof 20 and the waterproof membrane layer 11 at the corresponding position of the connector 124 to melt and contact to form a molten column. After the waterproof membrane layer is completed 11 and the flexible roof 20 after welding, the first magnetic metal ring 122, the isolation magnetic metal ring 123 and the connector 124 will be wrapped by the molten column, isolated from the outside moisture, and the first magnetic metal ring 122 and the isolation magnetic metal ring 123, as well as between two adjacent isolated magnetic metal rings 123, are connected by connectors 124. When corrosion occurs in the peripheral isolated magnetic metal rings 123, the corrosion is not easy to diffuse to the inner layer through the connectors 124, thereby effectively improving the The anti-corrosion performance of the magnetic metal mesh layer 12 is improved, the welding stability is improved, and the service life of the flexible roof support unit is further improved.

During the process of melting and solidification of the connecting member 124 under the action of high temperature, there is a possibility of forming air holes therein. During the welding process, if the connector 124 melts, resulting in the final formation of air holes, then it is easy for water vapor to invade the inner layer of the magnetic metal mesh layer 12 through the air holes, and then the magnetic metal mesh layer 12 is corroded. In order to ensure that the connecting piece 124 will not melt, so when selecting the connecting piece 124, a material with a melting point higher than that of the flexible roof 20 and the waterproof membrane layer 11 should be selected, so that the waterproof membrane layer 11 and the waterproof membrane layer 11 will When the melting temperature of the flexible roof 20 is still lower than the melting point of the connecting piece 124, that is, the connecting piece 124 will not melt during the welding process, thereby avoiding the occurrence of pores due to melting and affecting the anti-corrosion performance.

Optionally, as shown in FIG. 8 , the magnetic metal mesh 121 is ring-shaped, and the first magnetic metal ring 122 is arranged along the outer edge of the magnetic metal mesh 121 .

Specifically, as shown in FIG. 8 , the magnetic metal mesh 121 can be set to be ring-shaped, and the middle part is hollowed out, so that the service life of the flexible roof support unit is not affected, and the waterproof coiled material layer 11 is not damaged during installation. The use area of the magnetic metal mesh 121 can be reduced, and the material cost of the flexible roof support unit can be effectively reduced.

Optionally, the support 10 includes a boss 101, a screw 102, a fastener 103 and a waterproof membrane layer 11; the boss 101 is arranged on the side of the waterproof membrane layer 11 away from the flexible roof 20; the screw 102 is connected to the boss 101 , and pass through the waterproof membrane layer 11 and the magnetic metal mesh layer 12 in turn; when the flexible roof support unit is installed on the flexible roof 20, the screw 102 passes through the installation hole 201 and the flexible roof 20 in turn and is connected with the fastener 103 .

Specifically, the support 10 includes a boss 101, a screw 102 and a fastener 103. The boss 101 is integrally connected with the side of the waterproof coiled material layer 11 away from the flexible roof 20 to ensure that there will be no water leakage. At this time, the staff can open the installation hole 201 at the corresponding position of the flexible roof 20 according to the opening of the roof, and then lay the flexible roof 20 on the roof, and then insert the screw 102 into the installation hole 201 and the opening of the roof in sequence, and from the roof The lower end surface is exposed, and then the fastener 103 is connected with the end of the screw rod 102 exposed on the lower end surface of the roof, so that the flexible roof 20 and the flexible roof support unit are fixed on the roof.

Optionally, the mesh size of the holes in the magnetic metal mesh layer 12 is 150 mesh to 350 mesh.

Specifically, as shown in Figure 9, in the embodiment of the present utility model, the ratio of the hole length to the hole diameter of the magnetic metal mesh layer 12 is less than 0.5, which belongs to thin-walled holes. 20 To achieve a better welding effect after melting, it is necessary to make the flow rate of the above-mentioned fluid through the hole in a suitable range, and then the appropriate size and mesh number of the hole can be obtained through flow calculation. The flow formula for fluid flowing through a thin-walled small hole is:

Among them, A _T = πd ² /4, represents the cross-sectional area of the small hole, d represents the aperture of the small hole, A _e = πd _e ² /4 represents the shrinkage cross-sectional area, d _e represents the fluid cross-sectional diameter when the fluid flows out of the small hole, C _c represents the section shrinkage coefficient, _ve represents the average flow velocity of the fluid flowing through the small hole, C _v represents the small hole velocity coefficient, Δp represents the pressure difference before and after the small hole, ρ represents the fluid density, and C _q represents the flow coefficient.

In the embodiment of the present utility model, the magnetic metal mesh 121 can be made of a magnetic wire with a diameter of 0.5 mm. The reliability of the connection between the roof 20 and the waterproof coiled material layer 11 leads to water leakage and the corrosion of the magnetic metal mesh layer 12. Through the theoretical calculation of the flow combined with the experimental detection, the purpose of the holes on the magnetic metal mesh layer 12 The number should be 150 mesh-350 mesh. When the mesh number is less than 150 mesh, the size of the hole is too large, and the magnetic metal mesh layer 12 needs a higher temperature to melt the flexible roof 20 and the waterproof membrane layer 11 in the area corresponding to the hole. , so it is easy to cause damage to the waterproof membrane layer 11 and the flexible roof 20, resulting in a problem of reduced service life; when the mesh number is higher than 350 mesh, the size of the hole is small, and the flexible roof 20 and the waterproof membrane layer 11 are welded and connected The formed columnar structure will be relatively small, and the molten fluid cannot pass through the holes, so that the welding peeling force between the flexible roof 20 and the waterproof membrane layer 11 is greatly reduced. Therefore, preferably, the mesh size of the holes in the magnetic metal mesh layer 12 is 150 mesh to 350 mesh.

As shown in Figures 10 to 11, the embodiment of the utility model also provides a heating and fixing device for fixing the above-mentioned flexible roof support unit on the flexible roof 20.
