DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] Reference Figure 1-5 , an assembled photovoltaic curtain wall, comprising an L-shaped bracket 2, the L-shaped bracket 2 being installed on one side of the upper part of a wall 1;

[0029] Since photovoltaic panels are installed on the outside of buildings, when used as curtain walls, sunlight shines on the photovoltaic panels, and the photovoltaic panels absorb light energy. However, a large amount of heat is generated during the operation of the photovoltaic panels, and a large amount of heat is accumulated on the inside of the curtain wall, causing the temperature of the photovoltaic panels connected to the power generation components to rise. The power generation efficiency of the photovoltaic panels is directly related to the temperature of the components. When the temperature exceeds the normal working temperature, the power generation efficiency of the photovoltaic panels will decrease.

[0030] A combined angle bracket component 3 is installed on the side of the L-shaped bracket 2 away from the wall 1, and a ceramic plate 5 is detachably installed at the lower part of the combined angle bracket component 3. Photovoltaic panels 6 are detachably installed at the upper and lower ends of the ceramic plate 5 through clamps. A channel for air circulation is provided between the photovoltaic panel 6 and the ceramic plate 5, and a drainage box 13 is installed on the ceramic plate 5 at the end. The drainage box 13 is connected to the confluence pipe 9 through a plurality of connecting pipes 14 to form a circulating flow of air;

[0031] The ceramic plate 5 is fixedly installed on the wall 1 by using an L-shaped bracket 2 and a combined angle code assembly 3. At the same time, a plurality of partitions 10 are arranged on the side of the ceramic plate 5 close to the photovoltaic panel 6, so that a chamber 15 is formed between two adjacent partitions 10 in the vertical line. A plurality of photovoltaic panels 6 are distributed in a rectangular array outside the wall 1, so that in the horizontal direction, a plurality of chambers 15 are linearly distributed. External air enters the chamber 15 from one end of the chamber 15. When passing through, the formed airflow will take away the heat generated by the photovoltaic panel 6 when it is working. The hot air flow is collected in the drainage box 13 and enters the manifold 9 through the connecting pipe 14. Due to the characteristic that the heat flow will surge upward, a fan is arranged at the bottom of the manifold 9 to quickly move the heat flow to the upper part of the manifold 9;

[0032] The clamping parts include a lower bracket 7, an upper bracket 8, a lower bracket 16, and an upper bracket 17. The upper bracket 17 and the lower bracket 16 are respectively installed on one side of the ceramic plate 5. The lower bracket 7 and the upper bracket 8 are respectively clamped on the inner sides of the upper bracket 17 and the lower bracket 16. The photovoltaic panel 6 is vertically clamped between the inner sides of the lower bracket 7 and the upper bracket 8. The ceramic plate 5 is fixed by combining the angle code components 3, and then the lower bracket 7 and the upper bracket 8 are clamped on the lower bracket 16 and the upper bracket 17. In this way, the photovoltaic panel 6 can be moved from the side to between the lower bracket 7 and the upper bracket 8, and then the photovoltaic panel 6 can be assembled, which can effectively realize the rapid assembly of the photovoltaic panel 6;

[0033] A plurality of partitions 10 are installed in parallel on one side of the ceramic plate 5, and a chamber 15 is formed between two adjacent partitions 10. The plurality of chambers 15 are connected to the drainage box 13. A pressing block 4 is installed on one side of the combined angle code component 3. The bottom of the pressing block 4 fits with the upper bracket 8, and the upper bracket 8 fits tightly on the photovoltaic panel 6.

[0034] A fan is installed at the bottom of the conduit 9. Since the heat flow tends to surge upward, a fan is installed at the bottom of the conduit 9 to quickly move the heat flow to the upper part of the conduit 9.

[0035] Example 2

[0036] As photovoltaic power generation is promoted as a clean energy source, many regions are trying to install photovoltaic curtain walls outside buildings to achieve self-generation and self-use of electricity. However, in some areas, the temperature difference between morning and evening is large. When the photovoltaic panels 6 start working in the early morning, the external temperature is much lower than the internal temperature when the photovoltaic curtain wall is working. In this way, when the external cold airflow contacts the external hot airflow, it will cause liquefaction. The generated droplets will adhere to the back of the photovoltaic panels 6 and the power generation components, which may affect the power safety of the equipment.

[0037] refer to Figure 6-7The difference between this embodiment and embodiment 1 is that a liquefaction-proof structure 11 is provided on the inner side of each chamber 15, and the liquefaction-proof structure 11 includes an outer cover 111, an inner cover 112, a desiccant 113, a first through hole 114, and a second through hole 115. The inner cover 112 is fixed to the inner side of the outer cover 111 by a column, and the first through hole 114 and the second through hole 115 are respectively and evenly arranged on the outer side of the outer cover 111 and the inner cover 112, and the desiccant 113 is filled on the inner side of the inner cover 112, and a guide groove 116 is provided in the middle of one side of the outer cover 111 close to the photovoltaic panel 6;

[0038] A guide plate 12 is symmetrically arranged between the guide groove 116 and the inner side of the outer cover 111, and the guide plate 12 is arranged obliquely, and a gap is arranged between the outer cover 111 and the inner cover 112;

[0039] On the basis of not affecting the normal flow of gas, an anti-liquefaction structure 11 composed of an outer cover body 111 and an inner cover body 112 is arranged inside the chamber 15, and the inner cover body 112 is filled with a desiccant 113. The cold airflow entering from one end of the chamber 15 and the hot airflow generated by the photovoltaic panel 6 meet in the gap between the outer cover body 111 and the inner cover body 112. When flowing along the chamber 15, most of the airflow moves through the gap between the outer cover body 111 and the inner cover body 112, and a small part moves inside the inner cover body 112, thereby ensuring the normal passage of the airflow and effectively realizing the adsorption and drying of the appearing water vapor by the desiccant 113. In this way, the equipment can be used normally even in areas with lower temperatures and areas with large temperature differences between morning and evening.

[0040] Example 3

[0041] When installing the outer cover 11, since the entire wall 1 has a plurality of chambers 15 distributed in the horizontal direction on the outside, it is necessary to install the same number of outer covers 111 as the number of chambers 15 on the inner side of the chamber 15, and the efficiency is affected by the single installation;

[0042] refer to Figure 6 The difference between this embodiment and embodiment 1 is that two adjacent outer covers 111 are hinged together by a hinge and are linearly distributed inside several chambers 15; the guide groove 116 and the guide plate 12 can assist the airflow to enter between the outer cover 111 and the inner cover 112.

[0043] A plurality of outer covers 111 are detachably connected end to end in sequence by using a hinge, so that the outer covers 111 can be pushed into the chambers 15 whose positions match each other in sequence to complete the installation.

[0044] The working principle of the device is:

[0045] Since photovoltaic panels are installed on the outside of buildings, when used as curtain walls, sunlight shines on the photovoltaic panels, and the photovoltaic panels absorb light energy. However, a large amount of heat is generated during the operation of the photovoltaic panels, and a large amount of heat is accumulated on the inside of the curtain wall, causing the temperature of the photovoltaic panels connected to the power generation components to rise. The power generation efficiency of the photovoltaic panels is directly related to the temperature of the components. When the temperature exceeds the normal working temperature, the power generation efficiency of the photovoltaic panels will decrease.

[0046] Based on this, an L-shaped bracket 2 and a combined angle code assembly 3 are used to fix the ceramic plate 5 on the wall 1. At the same time, a plurality of partitions 10 are arranged on the side of the ceramic plate 5 close to the photovoltaic panel 6, so that a chamber 15 is formed between two adjacent partitions 10 in the vertical line. A plurality of photovoltaic panels 6 are distributed in a rectangular array outside the wall 1, so that in the horizontal direction, a plurality of chambers 15 are linearly distributed. External air enters the chamber 15 from one end of the chamber 15. When passing through, the formed airflow will take away the heat generated by the photovoltaic panel 6 when it is working. The hot air flow is collected in the drainage box 13 and enters the manifold 9 through the connecting pipe 14. Due to the characteristic that the heat flow will surge upward, a fan is arranged at the bottom of the manifold 9 to quickly move the heat flow to the upper part of the manifold 9;

[0047] During installation, the ceramic plate 5 is fixed by combining the angle code assembly 3, and then the lower bracket 7 and the upper bracket 8 are clamped on the lower clamping frame 16 and the upper clamping frame 17, so that the photovoltaic panel 6 can be moved from the side to between the lower bracket 7 and the upper bracket 8, and then the photovoltaic panel 6 can be assembled, which can effectively realize the rapid assembly of the photovoltaic panel 6;

[0048] Based on this, without affecting the normal flow of gas, an anti-liquefaction structure 11 composed of an outer cover body 111 and an inner cover body 112 is arranged inside the chamber 15, and the inner cover body 112 is filled with a desiccant 113. The cold airflow entering from one end of the chamber 15 and the hot airflow generated by the photovoltaic panel 6 meet in the gap between the outer cover body 111 and the inner cover body 112. When flowing along the chamber 15, most of the airflow moves through the gap between the outer cover body 111 and the inner cover body 112, and a small part moves inside the inner cover body 112, thereby ensuring the normal passage of the airflow, and at the same time effectively realizing that the water vapor that appears can be adsorbed and dried by the desiccant 113. In this way, the equipment can be used normally even in areas with lower temperatures and areas with large temperature differences between morning and evening.

[0049] The guide groove 116 and the guide plate 12 can assist the airflow to enter between the outer cover 111 and the inner cover 112 .

[0050] When installing the outer cover 11, since the entire wall 1 has a plurality of chambers 15 distributed in the horizontal direction on the outside, the outer cover 111 having the same number as the chamber 15 needs to be installed on the inner side of the chamber 15. Single installation affects the efficiency. A hinge is used to detachably connect the plurality of outer covers 111 end to end in sequence, so that the outer covers 111 can be pushed into the chambers 15 whose positions match each other in sequence to complete the installation.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
