Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building photovoltaic integration, in particular to a photovoltaic heat preservation and decoration structure integrated system for building outer walls. BACKGROUND

[0002] In response to the national double carbon target policy, actively carry out building empowerment, and building photovoltaic integration has become a general trend. Building photovoltaic integration has multiple application scenarios, such as photovoltaic curtain wall, power generation glass, photovoltaic roof (commonly used in industrial plants), etc. However, building photovoltaic integration has certain limitations in the application of building outer walls. There are currently three main forms of photovoltaic application on building outer walls: The first is the external hanging type of photovoltaic modules, which belongs to the BAPV (Building Application Photovoltaic) form. That is, after the outer wall insulation layer and the facing layer are completely constructed, photovoltaic supports (keels) and photovoltaic modules are installed on the building outer wall (or near the outer wall), resulting in redundant construction steps, longer construction period, and failure to achieve simultaneous construction of insulation materials and photovoltaic materials.

[0003] The second is the BIPV form, which uses "photovoltaic heat preservation and decoration integrated panels". This integrated panel forcibly bonds insulation materials and photovoltaic modules together and is directly installed on the building outer wall as a whole. When the photovoltaic module needs to be replaced, the faulty integrated panel is removed, causing a local lack of insulation materials on the building and affecting the insulation performance of the building (i.e., there is a thermal bridge).

[0004] The third method is more complex and also belongs to the BIPV form. There are two construction schemes, one for new buildings and one for existing buildings for "overlapping" installation. Taking a new building as an example, the implementation process is as follows: a steel structure frame and purlin are erected, a steel mesh is laid on the outside of the purlin, fireproof insulation cotton (usually rock wool or glass wool) is laid on top of the steel mesh, and finally a lightweight photovoltaic module with a metal back plate (note: usually aluminum-zinc plated plate) is laid. As can be seen, due to the load-bearing capacity, this scheme can only use lightweight photovoltaic modules, and the application scenario is relatively single, generally applied to industrial plants with low heat preservation and energy saving requirements of steel structures, but not suitable for civil buildings, public buildings, industrial buildings, etc. with reinforced concrete or aerated concrete base walls.

[0027] The present embodiment provides a photovoltaic heat preservation decoration structure integrated system for building outer wall (hereinafter referred to as "the present application system"), as shown in Figures 1-10 It comprises a photovoltaic module 100, a heat preservation module and a connecting and fixing module. The connecting and fixing module comprises: At least two keels 310 can be fixed on the wall surface 400 in parallel; The connecting assembly comprises a bearing groove 346, and the connecting assembly can be fixed on each keel 310 to form the oppositely arranged bearing grooves 346 between adjacent keels 310; The photovoltaic module 100 comprises a photovoltaic panel 110; Among them, The heat preservation module can be fixed on the wall surface 400 and located between the keels 310; The photovoltaic panel 110 can be arranged between the oppositely arranged bearing grooves 364 for fixation.

[0028] ​The photovoltaic heat preservation decoration structure integrated system for building outer wall provided by the application can directly fix the keels 310 on the wall surface 400, thereby increasing the overall bearing capacity; then, the heat preservation modules are fixed on the wall surface 400 and located between the keels 310, the keels 310 play a supporting and stabilizing role on the heat preservation modules, and the fixing stability of the heat preservation modules is improved; the connecting assembly of the connecting and fixing module is used to fix the photovoltaic panel 110 between the bearing grooves 346, so as to realize the stable fixing of the photovoltaic panel 110. Thus, the heat preservation modules and the photovoltaic modules 100 can be installed on the wall surface region by region, and the two are simultaneously constructed, thereby improving the construction efficiency and shortening the construction period; in addition, the keels can be directly fixed on the wall surface 400, the heat preservation modules are fixed on the wall surface 400 and located between the keels 310, so that the fixing of the heat preservation modules is more stable; the photovoltaic panel 110 is fixed on the wall surface by the connecting and fixing module, and the fixing stability of the photovoltaic module 100 is also increased.

[0029] It should be noted that, in order to ensure that the connecting and fixing module and the heat preservation module can be flatly and firmly attached to the wall surface, the wall surface can be subjected to a leveling process (a treatment process for leveling, repairing, filling pits and eliminating unevenness of the wall surface by using cement mortar) before the photovoltaic heat preservation decoration structure integrated system for building outer wall of the application is arranged on the wall surface, so as to form a leveling layer 410.

[0030] In a preferred embodiment of the above embodiment, as shown in Figure 1 When the connecting assembly is fixed on each of the keels 310, the bearing groove 364 has a preset distance from the keel 310, so that when the photovoltaic panel 110 is arranged between the oppositely arranged bearing grooves 346, a preset space is formed between the photovoltaic panel 110 and the heat preservation module.

[0031] As in the existing BIPV scheme, since the photovoltaic assembly has a high degree of adhesion with the heat preservation material, the photovoltaic assembly is poor in heat dissipation, and high-temperature operation of the assembly is easily caused in summer, which not only reduces the power generation capacity of the assembly, but also has potential safety hazards and other problems.

[0032] In the scheme of the present embodiment, a preset space is formed between the photovoltaic panel 110 and the heat preservation module, so that the heat on the surface of the photovoltaic panel 110 can be taken away by the air on the back of the photovoltaic panel 110, thereby preventing the photovoltaic panel 110 from overheating and affecting its normal operation and service life; on the other hand, the preset space can serve as a heat insulation space between the photovoltaic panel 110 and the heat preservation module, so that the heat of the photovoltaic panel 110 irradiated by the sun will not be further introduced into the building through heat conduction between the photovoltaic panel 110 and the heat preservation module, thereby reducing the energy required for indoor cooling due to indoor temperature rise caused by summer sunlight, and thus being more green and environmentally friendly.

[0033] In a preferred embodiment of the above embodiments, such as Figures 2-3 As shown, the keel 310 includes: a first mounting wall 311 for fixing to the wall surface, a protruding rib 312 located on the side of the keel away from the first mounting wall 311 and disposed opposite to it, and a first connecting wall 313 connecting the first mounting wall 311 and the protruding rib 312.

[0034] This embodiment provides a specific structure for the keel 310, which can be fixed to the wall 400 by the first mounting wall 311. The protruding rib 312 can increase the load-bearing strength of the keel 310 on the one hand, and on the other hand, the protruding rib 312 and the first connecting wall 313 facilitate a more stable connection of components.

[0035] Specifically, the cross-section of the keel 310 can be... Figure 2 The C-type shown, or, it can be... Figure 3 Type A, etc., are shown.

[0036] In a preferred embodiment of the above embodiments, such as Figures 1-6 As shown, The connection component includes: The first connector 320 has a cross-section in the shape of a "Z" and includes a second mounting wall 321, a first bearing wall 322, and a second connecting wall 323 in the shape of a U connected between the two. The second connector 330 includes a third mounting wall 331, a second bearing wall 332, and the third connecting wall 333 connected between the two. The frame 340 includes a mounting portion and the bearing groove 346; Among them, for the adjacent sides of two parallel keels 310 (such as...) Figure 1 As shown, the lower side of the upper keel 310 (especially the first connecting wall 313 and the protruding rib 312 on the lower side of the keel 310) and the upper side of the lower keel 310 (especially the first connecting wall 313 and the protruding rib 312 on the upper side of the keel 310) are connected by the second connecting wall 323 of the first connector 320, which is fitted into the keel 310. Figure 1 When the protruding rib 312 of the upper keel 310 is present, the second mounting wall 323 can be located inside the keel 310 and can be connected to the first connecting wall 313, and the first bearing wall 322 can be located outside the keel 310 in a direction away from the wall surface 400; a second connector 330 can be provided on another keel ( Figure 1the third mounting wall 331 is fixed to the outer side of the first connecting wall 313, and the second bearing wall 332 can be located outside the keel 310 in a direction away from the wall surface 400; the frame 340 can be fixed to the (first bearing wall 322 of the upper keel, the second bearing wall 332 of the lower keel, and the third bearing wall 333 of the second connecting piece 330) through its mounting portion, respectively.

[0038] As shown in Figure 1 , Figure 4 the first connecting piece 320 can be fixed to the first connecting wall 313 of the keel 310 through the second mounting wall 321 thereof, and the second connecting wall 323 can be sleeved on the convex rib 312 of the keel 310, so as to further limit the movement of the first connecting piece 320 in the left-right direction as shown in Figure 1 , thereby achieving stable fixation of the first connecting piece 320.

[0039] As shown in Figure 1 , Figure 5 the second connecting piece 330 can be fixed to the first connecting wall 313 through the third mounting wall 331, and the third connecting wall 333 can be abutted against the outer surface of the convex rib 312, so that the second connecting piece 330 can be stably fixed to the keel 310.

[0040] As shown in Figure 1 , Figure 1 the frame 340 can be fixed to the (first bearing wall 322 of the upper keel, the second bearing wall 332 of the lower keel, and the third bearing wall 333 of the second connecting piece 330) through its mounting portion, respectively. Figure 1The second bearing wall 332 of the lower keel, to form the oppositely arranged bearing grooves 346, so that the photovoltaic panel 110 can be stably fixed through the bearing grooves 346. At the same time, the outer side of the lower convex rib 312 of the upper keel 310 supports the bending moment of the first connecting member 320 caused by the pressure of the frame 340, and the outer side of the upper convex rib 312 of the lower keel 310 supports the bending moment of the second connecting member 330 caused by the pressure of the frame 340, preventing large deformation of both caused by the bending moment, so as to ensure the stability of the overall structure.

[0042] The present embodiment gives a specific frame 340 structure, which can be fixed to the first bearing wall 322 of the first connecting member 320 through the mounting portion (such as its fifth wall 345), and fixed to the second bearing wall 332 of the second connecting member 330 through the mounting portion (such as its first wall 341), so as to form oppositely arranged bearing grooves 346. In addition, the frame 340 of only one structure can be respectively applied to the first connecting member 320 and the second connecting member 330, so as to save the types of materials required by the "system of the application", thereby saving product complexity and manufacturing / purchasing cost.

[0060] In the embodiment, the keel and / or the frame are made of insulating material, which can avoid complex grounding connection.

[0061] For the insulating material, specifically, it can be selected from any one or a combination of two or more of unsaturated resin material, phenolic resin material, polyurethane material, and glass steel material.

[0062] In one preferred embodiment of the above embodiment, as shown in Figures 7-10 the photovoltaic module 100 further includes a current output component and an online monitoring component; the current output component includes an inverter 140 and a line connecting the photovoltaic panel 110 and the inverter 140; the online monitoring component includes: a monitor 120 that monitors the operating data (such as working current, working voltage, operating temperature, and power generation power) of the photovoltaic panel 110; a transceiver 130 that is electrically connected to the monitor 120 to send the operating data (such as uploading to the background through WIFI, 4G, and / or RS485 communication mode, and the background performs data analysis) or receives external data to send to the monitor 120 (such as being able to control the abnormal photovoltaic panel 110 to shut down, off-grid, and the like to ensure the normal work of other components in the string); a temperature sensor 150 that is disposed outside the monitor 120 and is electrically connected to the monitor 120, and detects the temperature of the shaded surface of the photovoltaic panel 110. A suitable adhesive can be applied to the edge (non-detection area) of the temperature sensor 150 and fixedly bonded to the shaded surface of the photovoltaic panel 110; to facilitate accurate measurement of the operating temperature of the component, heat-conducting silicone grease or other suitable materials with high thermal conductivity can be applied between the temperature sensor 150 and the photovoltaic panel 110.

[0063] Regarding the connection between the photovoltaic panel 110 and the inverter 140, those skilled in the art can implement this using existing technologies as needed, and will not be elaborated further here. For example, the photovoltaic panels 110 can be connected in series and then connected to the inverter 140; for example, the photovoltaic panels 110 can be connected in parallel and then connected to the inverter 140; for example, the photovoltaic panels 110 can be grouped, with each group connected in series, and then the groups connected in parallel to connect to the inverter 140, etc.

[0064] Existing building-integrated photovoltaic (BIPV) systems lack effective monitoring of the photovoltaic panel's operating status. Temperature monitoring, in particular, is often inadequate; even when temperature control and detection units are installed, they are usually integrated into the monitor itself, failing to accurately reflect the photovoltaic panel's operating temperature. When the photovoltaic panel's operating temperature is too high, there is a lack of necessary warnings, potentially leading to risks such as fires.

[0065] The online monitoring component provided in this embodiment enables accurate monitoring of the operating status of the photovoltaic panel 110 via the monitor 120. Meanwhile, the temperature sensor 150 is externally mounted on the monitor 120, thereby reducing the problem of inaccurate temperature detection caused by the monitor 120 itself generating heat and its casing being heat-resistant.

[0066] Preferably, the monitor is a power line carrier monitor. Power line carrier (PLC) is a special communication method that uses power lines as the information transmission medium for voice or data transmission. This eliminates the need for separate communication lines, reducing redundant design of DC communication power supplies. Figure 8 As shown, a one-to-one monitor 120 (one monitor 120 connected to one photovoltaic panel 110) is provided; as Figure 9 As shown, a monitor 120 is provided that connects to two photovoltaic panels 110 (one monitor 120 connects to two photovoltaic panels 110). Thus, after the monitor 120 is connected to the corresponding photovoltaic panel, the monitors 120 can be connected in series and / or in parallel as needed before being connected to the inverter 140. The monitor 120 and the photovoltaic panel 110, and / or the monitor 120 itself, can be connected via existing MC4 interfaces 121 (MC4 male and MC4 female). While directing the current from the photovoltaic panel 110 to the inverter 140, the monitor 120 can also transmit operating data.

[0067] For the power line carrier monitor, commercially available products can be purchased according to specific needs, which will not be described here. Preferably, the power line carrier monitor has an open circuit and bypass switching function, so as to be able to disconnect the corresponding photovoltaic panel 110 according to the received data from the transceiver 130. Preferably, the power line carrier monitor has a bypass function, that is, when an abnormal photovoltaic panel 110 occurs, it can skip (i.e., short circuit) the abnormal photovoltaic panel to ensure that other components in the group string work normally.

[0068] Preferably, the monitor 120 is built-in temperature sensing element, so as to be able to monitor the working temperature of the monitor itself in real time.

[0069] Preferably, the temperature sensor is a Pt100 platinum thermal resistance, which can realize temperature measurement of-50~+200℃, meeting the requirements of temperature detection of the photovoltaic panel 110.

[0070] Preferably, the monitor is provided with a fixing hole 123, which can be specifically provided on the connecting plate 122 of the monitor; and / or, the monitor 120 is provided with an elastic back clip 124. Thus, the monitor 120 can be conveniently installed on the photovoltaic panel 110.

[0071] Although the embodiments of the present application are described above, the present application is not limited to the above specific embodiments and application fields, and the above specific embodiments are only illustrative and guiding, but not limiting. Those skilled in the art can make many forms under the guidance of the present application and without departing from the scope protected by the claims of the present application, which all belong to the present application.
