[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0039] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] The existing power generation glass roof is mainly to lay an additional layer of monocrystalline photovoltaic modules directly on the roof of the factory or office building. Although this solution can use the roof to generate electricity, the photovoltaic modules and the building roof are independent systems and are not combined. The photovoltaic modules are connected to the building roof through brackets, which is equivalent to increasing the weight of the roof and constructing it twice. The photovoltaic modules and the roof need to be designed, purchased and constructed independently, which takes a long time and has poor economic efficiency. There are also many cross-cutting problems in the later use and maintenance. Materials are wasted to a large extent and costs are increased.

[0043] In order to solve the above problems, a cadmium telluride power generation glass roof system is proposed. Figure 1 The embodiment of the present application provides a cadmium telluride power generation glass roof system, including a glass installation frame 1, a keel assembly 2 and a connector 3, the keel assembly 2 includes a keel body and two placement racks 24; the bottom of the connector 3 is used to be installed on the main steel structure 4 of the roof, the top of the connector 3 is connected to the bottom of the keel body, and the top of the keel body is provided with a mounting groove 21; the glass installation frame 1 is provided with two plug-in components 13, and the two plug-in components 13 of two adjacent glass installation frames 1 close to each other are plugged and matched with the mounting groove 21 inside the mounting groove 21, and the glass installation frame 1 is used to install cadmium telluride power generation glass; the two placement racks 24 are respectively connected to the outer side walls on both sides of the keel body, so that the two placement racks 24 form storage grooves with the keel body on both sides of the keel body; a first sealing strip 16 is provided between the two adjacent glass installation frames 1, and the two sides of the first sealing strip 16 are respectively connected to the two glass installation frames 1. The length of the cross section of the keel component 2 parallel to the main steel structure 4 is 50mm-200mm, and the length of the cross section of the keel component 2 perpendicular to the main steel structure 4 is 50mm-300mm.

[0044] Compared with the existing traditional installation structure, the main keel (i.e., the keel assembly 2 in this embodiment) is redesigned, and the design of the secondary keel assembly is cancelled. During the manufacturing process, the cadmium telluride power generation glass is directly installed on the metal back frame of the corresponding size, and then the metal back frame is inserted into the keel assembly 2 to achieve the installation of the cadmium telluride power generation glass. On the one hand, the construction links can be reduced, and on the other hand, the cadmium telluride power generation glass can be made more stable relative to the metal back frame. At the same time, the combination of electricity and structure is achieved, so that photovoltaics can replace building materials, and building photovoltaic integration is achieved.

[0045] The specific installation method is: first, install the bottom of the connecting member 3 on the main steel structure 4 of the roof, and then place the keel assembly 2 on the top of the connecting member 3, and can strengthen the stability of the connecting joint and the keel assembly 2 when connected by means of clamping or bolting. A mounting groove 21 is provided on the side of the keel assembly 2 away from the connecting member 3, and the extension direction of the mounting groove 21 is parallel to the extension direction of the keel assembly 2, so as to facilitate the insertion of the connector 13 provided on one side of the glass mounting frame 1 into the mounting groove 21, thereby realizing the installation of the glass mounting frame 1 on the keel assembly 2, and at the same time, the stability of the connection between the glass mounting frame 1 and the keel assembly 2 can be strengthened by setting bolts.

[0046] Among them, refer to Figure 2-Figure 3 Two connectors 13 are installed on the side of the glass installation frame 1 close to the keel assembly 2. The connector 13 is a long strip structure. The extension direction of the connector 13 is parallel to the extension direction of the installation slot 21. In the actual installation process, several keel assemblies 2 are arranged at intervals. Two connectors 13 can just be inserted into the installation slots 21 of two adjacent keel assemblies 2. The same installation slot 21 can just place two connectors 13 close to each other in two adjacent glass installation frames 1. In this way, the above steps can be repeated to achieve the installation of several glass installation frames 1. A first sealing strip 16 is arranged between two adjacent glass installation frames 1 perpendicular to the extension direction of the keel assembly 2. The two sides of the first sealing strip 16 are respectively connected to the two glass installation frames 1 to achieve a sealing effect between the two glass installation frames 1.

[0050] During installation, first insert the connector 13 of the glass mounting frame 1 close to the second mounting member 12 into the mounting groove 21, and then insert the connector 13 of the other glass mounting frame 1 close to the first mounting member 11 into the mounting groove 21. At this time, insert the snap-in block into the snap-in groove to connect the two glass mounting frames 1.

The two waterproof rubber strips cooperate with the clamping block to achieve the sealing of the internal space of the second mounting member 12;

[0052] An elastic strip 14 is provided between the first mounting member 11 and the second mounting member 12. The elastic strip 14 is clamped and compressed by the side of the first mounting member 11 facing outdoors and the side of the second mounting member 12 facing outdoors, thereby sealing the first mounting member 11 and the second mounting member 12 facing outdoors. At the same time, during installation, sealant is poured into the gap between the elastic strip 14 and the first mounting member 11 and the gap between the elastic strip 14 and the second mounting member 12, respectively, to further enhance the sealing effect of the first chamber.

[0053] Optionally, in this embodiment, an auxiliary support member is provided on the side of the first mounting member 11 and the second mounting member 12 that are away from each other, and the two auxiliary support members are detachably connected to the first mounting member 11 and the second mounting member 12 via second bolts 19 .

The base 31 and the limiting member 32 are detachably connected. A limiting groove is set at the bottom of the keel assembly 2, and the limiting member 32 is embedded in the limiting groove.

[0056] The base 31 includes a bottom plate and two first connecting plates arranged perpendicular to the bottom plate. The bottom plate is detachably connected to the main steel structure 4 by fourth bolts. The two first connecting plates are arranged on the top of the base 31, and the extension surfaces of the two first connecting plates are parallel to each other.

[0057] A rubber layer is provided between the base 31 and the main steel structure 4 to prevent slipping and reduce shock.

[0058] The limiting member 32 includes a top plate and two second connecting plates arranged perpendicular to the bottom plate. The top plate is embedded in a limiting groove at the bottom of the keel assembly 2. The two second connecting plates are arranged at the bottom of the top seat, and the extension surfaces of the two second connecting plates are parallel to each other.

[0059] The two second connecting plates just clamp the two first connecting plates therein, and both the second connecting plates and the first connecting plates are provided with through holes for matching use, and the third bolt 33 passes through the two second connecting plates and the two first connecting plates to achieve a detachable connection between the base 31 and the limiter 32.

When the connector 13 is inserted into the mounting groove 21, the first flexible member 22 and the second flexible member 23 abut against each other.

[0062] Optionally, the first flexible member 22 and the second flexible member 23 of the present embodiment are both in the shape of long strips, the first flexible member 22 is extended along the extension direction of the keel assembly 2, the second flexible member 23 is extended along the extension direction of the glass mounting frame 1, and the first flexible member 22 and the second flexible member 23 are arranged near the position where the glass mounting frame 1 and the keel assembly 2 are connected.

[0063] The first flexible member 22 and the second flexible member 23 have an arc-shaped section on the opposite side, which further increases the contact area between the first flexible member 22 and the second flexible member 23 and improves the sealing effect. The second flexible member 23 is installed on the plug-in 13, and the vertically upward side of the first flexible member 22 abuts against the glass installation frame 1, and the inward side of the first flexible member 22 abuts against the second flexible member 23 installed on the plug-in 13, thereby achieving double sealing between the keel assembly 2 and the glass installation frame 1.

A third sealing strip is provided at the position where the cadmium telluride power generation glass is installed on the glass installation frame 1, which is used to seal the gap between the cadmium telluride power generation glass and the glass installation frame 1.

[0070] It should be noted that the detachable connection achieved by other bolts such as the first bolt 18, the second bolt 19 and the third bolt 33 in this application is only an optional implementation of this embodiment. In other embodiments, the detachable connection can also be achieved by using snap-on methods.

[0071] The cadmium telluride power generation glass roof system of this embodiment, especially the design of the keel assembly 2 (i.e., the main keel), is verified by way of test examples.

[0072] Specifically, the length of the cross section of the keel component 2 parallel to the main steel structure 4 is 50mm-200mm, and the length of the cross section of the keel component 2 perpendicular to the main steel structure 4 is 50mm-300mm.

[0073] In order to support the technical effects corresponding to the above embodiments, the following experimental examples are provided:

[0074] In an experimental example, the structure is as in the aforementioned embodiment, wherein the cross-section of the keel assembly 2 along the installation direction of the glass installation frame is 150 mm, and the cross-section of the keel assembly along the installation direction perpendicular to the glass installation frame is 91 mm.

[0075] Firstly, the structural bearing capacity of the keel assembly is analyzed. Figure 6-Figure 8 , Figure 6 A transverse cross-sectional view of a keel assembly provided in an embodiment of the present invention, Figure 7A schematic diagram of the structure of a keel assembly provided in an embodiment of the present invention, Figure 8 The force diagram of the cross section of the keel assembly provided in the embodiment of the present invention, according to the curtain wall specification (JGJ-102) and the technical specification for skylights and metal roofs (JGJ255-2012), the standard value of wind load should not be less than 1.0KN / M2. Here, the minimum value allowed by the specification is considered, and the standard value of wind load is taken as 1.0KN / M2. The span of the keel assembly 2 support point is considered as 2m (the bearing capacity condition is consistent with the calculation of the crystalline silicon roof). The finite element analysis of the structural bearing capacity of the keel assembly 2 is performed:

[0076] Reference Figure 9-10 , Fig. 9 A deflection working condition diagram of a keel assembly provided in an embodiment of the present invention; Fig.10 A cloud diagram showing the calculation of the deflection of the keel assembly provided in an embodiment of the present invention;

[0077] Depend on Fig.10 It can be learned that the calculated deflection value of the keel component 2 is: 2.98mm<2000 / 180=11mm, which meets the applicability requirements under normal use;

[0078] Reference Figure 11-Figure 12 , Fig.11 A strength working condition diagram of a keel assembly provided in an embodiment of the present invention; Fig.12 The stress calculation cloud diagram of the keel assembly provided in the embodiment of the present invention; it can be known that the strength calculation of the keel assembly 2 is: 78.8MPA<85MPA, which meets the safety requirements under the limit state.

[0079] Glass installation frame 1: Glass installation frame 1 completely eliminates the slot connection specially designed by the aluminum alloy back frame, and realizes stiffness distribution through lateral plug-in to achieve structural deformation coordination. It greatly saves the material of keel component 2 and improves the construction speed. The load of the plug-in aluminum frame is distributed and calculated separately according to the principle of stiffness distribution.

[0080] in, Fig.10 and Figure 12-14 DMX (fixed) refers to the maximum displacement (Displacement Max), SMX refers to the largest solution in the node equivalent stress results, and SMN refers to the smallest solution in the node equivalent stress results. The specific results are shown in the figure.

[0081] Reference Fig.13 , Fig.13 The deflection calculation diagram of the glass installation frame provided in the embodiment of the present invention; it can be known that the deflection calculation value is: 5.3mm<1600 / 180=8.9mm, which meets the applicability requirements under normal use;

[0082] Reference Fig.14 , Fig.14 This is a strength calculation diagram of the glass installation frame provided in an embodiment of the present invention; it can be learned that the strength calculation is: 30MPA<85MPA, which meets the safety requirements under the limit state.

[0083] It can be seen that the structure of the improved keel assembly 2 can effectively meet the requirements of the standard value of wind load in the curtain wall specification (JGJ-102) and the technical specification for skylights and metal roofs (JGJ255-2012).

[0084] Secondly, the thermal performance of the keel assembly 2 was analyzed and calculated, and the thermal insulation performance of the scheme was quantitatively calculated according to the thermal calculation code for building doors, windows and glass curtain walls (JGJ / T151-2008).

[0085] The thermal insulation performance of the keel component 2 of the crystalline silicon water tank structure was analyzed by using THEERM, a special finite element software for thermal engineering of building maintenance structures developed by the Lawrence Berkeley National Laboratory in the United States.

[0086] Calculation results: Refer to Fig.15 , Fig.15 The temperature field calculation model diagram of the glass installation frame provided in the embodiment of the present invention, the heat transfer coefficient of the cadmium telluride power generation glass top system frame K = 1.6W / M2.K;

[0087] It can be seen from this that the structure of the improved keel assembly 2 can achieve a better thermal insulation effect.

[0088] Finally, a targeted design was carried out to address the shortcomings of the poor waterproof performance of the crystalline silicon roof system in the prior art, and all possibilities of leakage in the crystalline silicon solution were found out and the structural construction was thoroughly improved. At the same time, a complete theoretical calculation of the water tank depth and the water pressure difference of the rubber strip was carried out according to the rain curtain principle, forming a complete calculation method for watertight performance and a principle for evaluating the watertight performance level. The cadmium telluride power generation glass roof system of this embodiment can be designed accordingly according to the watertightness requirements of the actual project.

[0089] According to the Curtain Wall Code (JGJ-102) and the Technical Code for Skylights and Metal Roofs (JGJ255-2012), in areas affected by tropical storms and typhoons, the watertightness design value can be planned according to the following formula, and the fixed part value should not be less than 1000Pa:

[0090] P = 1000 μ Z μ S ω Ο

[0091] Where: Ρ is the watertightness design value (Pa); ω Ο is the basic wind pressure (kN / ㎡); μ Z is the wind pressure height variation coefficient; μ Sis the body shape coefficient, which can be taken as 1.2.

[0092] In other areas, the water tightness can be designed as 75% of the value calculated in paragraph 1, and the value of the fixed part should not be less than 700Pa;

[0093] Considering a certain area, the roof height is 20 meters, the area type is Class B, and the basic wind pressure W0 = 0.3KN / M2 (once in 50 years), the watertight performance design value P = 1000*1.23*1.2*0.3 = 443Pa. According to the pressure formula, P = ρgh. Assuming the density ρ is 1kg / m 3 When g takes the value of 9.8, h≈44.3mm<85mm, no leakage will occur, and the water tightness meets the requirements.

[0094] Note: For areas with high wind pressure, the 85mm liquid level height difference can also be adjusted by design. This solution is equipped with several sizes such as 100mm and 150mm, so that the cadmium telluride power generation glass roof system meets the watertightness requirements.

[0095] In an experimental example, the structure is as in the aforementioned embodiment, wherein the dimension of the cross section of the keel assembly along the installation direction of the glass installation frame is 50 mm, and the dimension of the cross section of the keel assembly along the installation direction perpendicular to the glass installation frame is 50 mm.

[0096] The dimensions of the corresponding keel components in this experimental example are simulated through the aforementioned experimental examples to obtain the results. It can be known that the structure of the improved keel component 2 can meet the requirements of the standard value of wind load in the curtain wall specification (JGJ-102) and the technical specification for skylights and metal roofs (JGJ255-2012), and can also achieve a good thermal insulation effect and meet the requirements of water tightness.

[0097] In an experimental example, the structure is as in the aforementioned embodiment, wherein the dimension of the cross section of the keel assembly along the installation direction of the glass installation frame is 200 mm, and the dimension of the cross section of the keel assembly along the installation direction perpendicular to the glass installation frame is 300 mm.

[0098] The dimensions of the corresponding keel components in this experimental example are simulated through the aforementioned experimental examples to obtain the results. It can be known that the structure of the improved keel component 2 can meet the requirements of the standard value of wind load in the curtain wall specification (JGJ-102) and the technical specification for skylights and metal roofs (JGJ255-2012), and can also achieve a good thermal insulation effect and meet the requirements of water tightness.

[0099] In summary, compared with the crystalline silicon water tank solution in the prior art, this embodiment can achieve effective optimization effects:

[0100] In view of the fact that crystalline silicon water tank products have a single color, cannot be transparent, cannot achieve patterns and colors, and have poor architectural effects, this solution uses cadmium telluride power generation glass components, which can achieve various colors and patterns while achieving efficient photovoltaic power generation, meeting the architectural effect requirements of various scenes. Colored cadmium telluride power generation glass has been put into practical use in many projects.

[0101] For fixed size:

[0102] Crystalline silicon modules can only be manufactured in standard sizes and cannot adapt to personalized building sizes and shapes. Cadmium telluride power generation glass can perfectly solve this problem through special cutting and splicing processes and has been put into practical use in multiple construction projects.

[0103] For low light power generation:

[0104] Crystalline silicon modules are sensitive to shadows and are prone to hot spot effects, which can cause fire and other safety hazards. Cadmium telluride power generation glass products have the electrical properties of low current and high voltage. At the same time, the internal circuit design of the product is specially designed to prevent hot spot treatment, which effectively solves the problem of hot spot effect.

[0105] The components have high temperature coefficients, high heat generation, and large heat losses in power generation.

[0106] Crystalline silicon modules have a high starting voltage and cannot generate electricity in the morning and evening. They can only work during the noon and afternoon periods when the radiation is strong. In addition, they absorb part of the infrared spectrum when working, causing the module temperature to rise quickly. Crystalline silicon modules are sensitive to temperature and have a high power temperature coefficient. As the temperature rises, the module efficiency drops rapidly. Cadmium telluride modules do not absorb infrared light, so they generate less heat. As the temperature rises, the power temperature coefficient of cadmium telluride modules is low, so the power loss is small under the same temperature rise.

[0107] For thickness restrictions

[0108] The standardized thickness of crystalline silicon module panels cannot be flexibly adapted to the wind pressure load in different regions, and its applicability is low. Cadmium telluride module products are more mature, with richer configurations and a variety of thickness series to choose from.

[0109] Low safety for structural forces

[0110] In view of the problems that the safety level of the metal main steel structure 4 of the crystalline silicon roof is low, there is no effective support connection in the direction of the secondary keel assembly 2, and the wind pressure resistance is low, this embodiment carries out structural mechanics simulation analysis and theoretical calculations and proposes an innovative solution, which not only saves materials, but also greatly simplifies the construction process, greatly improving the construction period and economy.

[0111] It is calculated by referring to the above experimental example that the structural stress safety of the cadmium telluride power generation glass roof system is higher than that of the prior art.

[0112] For poor thermal insulation and energy saving performance:

[0113] The thermal insulation performance of the crystalline silicon roof system keel assembly 2 and assembly is poor, and does not meet the energy-saving requirements of the lighting roof. Cadmium telluride photovoltaic panels have double-glass assemblies, triple-glass assemblies, hollow assemblies, etc., which can meet the thermal insulation and energy-saving requirements in various scenarios. Referring to the calculation of the above experimental example, it is known that the thermal insulation performance of the cadmium telluride power generation glass roof system frame is better.

[0114] For watertight performance

[0115] Targeted designs were made to address the shortcomings of the crystalline silicon roof system’s poor waterproof performance. All possibilities of leakage in the crystalline silicon solution were identified and the structural construction was thoroughly improved. At the same time, a complete theoretical calculation of the water tank depth and the water pressure difference of the rubber strip was carried out based on the rain curtain principle, forming a complete calculation method for watertight performance and a principle for assessing the watertight performance level. The cadmium telluride solution can be designed accordingly based on the watertight requirements of the actual project.

[0116] It is calculated by referring to the above experimental example that the cadmium telluride power generation glass roof system meets the watertightness requirements.

[0117] For hiding and repairing cables:

[0118] Aiming at the problem that the indoor cables 26 of the crystalline silicon roof system cannot be hidden, are randomly laid out, difficult to repair, and have poor effects, the frame of the keel assembly 2 is specially designed, and according to the line characteristics of the string and the convergence, the wiring space for the DC and AC cables is reserved on the keel assembly 2. The electromechanical coordination is achieved, the lines are clearer and simpler, very beautiful, and easy to repair.

[0119] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.
