Description

Technical Field

[0001] The invention relates to the technical field of PVT heat collection components, in particular to a PVT heat collection component with a protective structure. Background Art

[0002] PVT heat collection components, also known as PVT panels, are a type of equipment that combines photovoltaic power generation and thermal energy utilization functions, usually consisting of photovoltaic panels and thermal collectors. It not only has the power generation function of traditional photovoltaic panels, but can also collect solar heat through thermal collectors for heating, hot water or other thermal energy utilization. The main advantage of this technology is that it improves energy utilization efficiency, converts solar energy resources into electricity and heat energy at the same time, thereby improving the overall energy utilization of the system.

[0003] The existing PVT panels have the following deficiencies in actual use:

[0004] 1. PVT panels are usually installed at an angle to better absorb solar energy. However, this installation method will increase the wind-exposed area and wind resistance in extreme weather such as strong winds, which will affect safety. If the fixing is not firm, the PVT panel may even be blown away.

[0005] 2. The main function of the glass cover installed on the upper surface of the PVT panel is to protect the inside of the PVT panel from the influence of the external environment, while allowing solar radiation to enter the inside of the PVT panel through the glass cover. However, due to the long-term exposure of the glass cover to the external environment, it will face a variety of problems. For example, when the PVT panel is not in working state at night, the glass cover is still exposed to the external environment, which will increase the probability of dust and pollutants adhering, thereby affecting the penetration of the glass cover; in the event of extreme weather such as hail, due to the lack of protective measures on the upper surface of the glass cover, the glass cover will be smashed and damaged; in the face of high temperature weather, after the PVT panel has been fully saturated to absorb solar energy, it will continue to be exposed to the sun for a long time, which will cause the components exposed to sunlight to age or be damaged, shortening its service life.

[0006] 3. PVT panels mainly collect heat through the direct area formed by the glass cover. When facing rainy days or insufficient light, the absorption efficiency will drop significantly, thus affecting the working efficiency of the PVT panels.

[0007] 4. PVT panels are usually fixed to the mounting bracket by welding or other methods, but this method cannot flexibly adapt to PVT panels of different sizes, and has poor stability and protection.

[0008] Therefore, we provide a PVT solar collector component with a protective structure. Summary of the invention

[0021] 1. In the present invention, the wind speed detector can detect the wind speed at the location of the PVT panel body in real time. Once the wind speed is detected to exceed the set safety threshold, the PVT panel body will be driven to adjust from an inclined state to a horizontal state.

[0022] 2. The present invention can cope with different weather and working conditions by adding protective plates on the front and back sides of the PVT panel body, and will not affect the side-by-side installation effect of the PVT panel body. When the PVT panel body is working normally, the protective plate is in an unfolded state, and the side coated with the reflective coating faces upward. At this time, the solar radiation can be reflected to the PVT panel body through the reflective coating, and the energy absorption efficiency can be enhanced even in rainy days or when the light is insufficient. When the PVT panel body is in a non-working state at night or in extreme weather such as high temperature and hail, the protective plate is in a buckled state. In this state, the protective plate covers the glass cover plate of the PVT panel body, which can prevent the adhesion of dust and pollutants, and at the same time protect the PVT panel body from damage by weather such as hail. In high temperature weather, the covering of the protective plate can also reduce the exposure time of the PVT panel body, thereby extending its service life. The dual role of the protective plate effectively enhances the protection function of the PVT panel body, which can not only improve energy efficiency under normal working conditions, but also protect the equipment from the influence of the external environment under non-working conditions, so that the PVT panel body is more adaptable to diverse weather conditions and improves its stability and reliability.

[0023] 3. The mounting bracket can be flexibly adjusted according to the different sizes of PVT panels, making it more applicable. By installing two sets of hook-type fixing seats on the left and right sides of the PVT panel body, and two sets of hook-type movable seats on the front and back sides, the PVT panel body is fixed from four directions, making the installed PVT panel body more stable, not easy to move or shake, improving its protective performance, and the installation process is simple and efficient.

The side of the main support rod 51 away from the hook-type fixing seat 52 is fixedly connected with a fixing rod 54. The front end of the side of the fixing rod 54 away from the main support rod 51 is fixedly connected with a fixing buckle seat 541. The inner side of the fixing buckle seat 541 is rotated to The main support rod 51 is rotatably connected with a connecting rod 1 55, and the rear end of the fixed rod 54 away from the main support rod 51 is slidably connected with a connecting rod 2 56, and the center position of the connecting rod 1 55 and the center position of the connecting rod 2 56 are rotatably connected. The lower surface of the main support rod 51 is fixedly connected with an I-shaped connecting seat 6, and the lower surface of the I-shaped connecting seat 6 is connected with an adjustment component 7 for adjusting the inclination angle of the PVT board body 1. The adjustment component 7 includes a long rod 71, and the front end of the long rod 71 is rotatably connected with a C-shaped seat 1 72, and the lower surface of the C-shaped seat 1 72 is fixedly connected with a fixing column 73, and the long rod 7 The rear end of 1 is rotatably connected with a C-type seat 2 74, the rear side of the C-type seat 2 74 is fixedly connected with an adjusting rod 75, the lower surface of the adjusting rod 75 is fixedly connected with a C-type seat 3 751, the inner side of the C-type seat 3 751 is rotatably connected with a connecting ear 76, the lower end of the connecting ear 76 is fixedly connected with a sliding buckle 761, the inner side of the sliding buckle 761 is detachably connected with a moving block 763, the lower surface of the fixed column 73 is fixedly connected with a cross beam 8, the rear side of the upper surface of the cross beam 8 is connected with a driving member 77 for driving the moving block 763 to move, and the lower surface of the cross beam 8 is connected with three groups of supporting legs 9.

[0044] The present invention responds to different weather and working conditions by adding protective plates 3 on the front and back sides of the PVT panel body 1. When the PVT panel body 1 is working normally, the protective plate 3 is in an unfolded state, and the side coated with the reflective coating 31 faces upward. At this time, the solar radiation can be reflected to the PVT panel body 1 through the reflective coating 31, and the energy absorption efficiency can be enhanced even in rainy days or when the light is insufficient. When the PVT panel body 1 is in a non-working state at night or in extreme weather such as high temperature and hail, the protective plate 3 is in a buckled state. In this state, the protective plate 3 covers the glass cover plate of the PVT panel body 1, which can prevent the adhesion of dust and pollutants, and at the same time protect the PVT panel body 1 from damage by weather such as hail. In high temperature weather, the covering of the protective plate 3 also helps to reduce the exposure time of the PVT panel body 1, thereby extending its service life. The dual role of the protective plate 3 effectively enhances the protection function of the PVT panel body 1, which can not only improve energy efficiency under normal working conditions, but also protect the equipment from the influence of the external environment under non-working conditions, so that the PVT panel body 1 is more adaptable to diverse weather conditions and improves its stability and reliability.

[0045] The wind speed detector 2 can detect the wind speed at the location of the PVT panel body 1 in real time (the wind speed detector 2 is installed in an independent individual in the vicinity of the PVT panel body 1. When multiple groups of PVT panel bodies 1 are installed, only one group of wind speed detectors 2 can be used for detection). When it is detected that the wind speed exceeds the set safety threshold, the driving member 77 drives the moving block 763 to slide, thereby indirectly driving the adjustment rod 75 to tilt. At this time, the PVT panel body 1 is adjusted from the tilted state to the horizontal state. This adjustment can reduce the wind-receiving area of ​​the PVT panel body 1, thereby reducing wind resistance, reducing the impact of wind on it, and improving its stability in windy weather.

[0046] The mounting bracket 5 can be flexibly adjusted according to the PVT panel bodies 1 of different sizes, making it more applicable and the installation process simple and efficient.

[0047] The wind speed detector 2 adopts a cup anemometer to detect the wind speed in the environment in real time. This wind speed detector 2 measures the speed of the wind through a rotating cup.

[0048] The reflective coating 31 may be an aluminum coating, which has good reflectivity and can effectively reflect solar radiation to the surface of the PVT panel body 1 to improve energy absorption efficiency. In addition, the aluminum coating also has good corrosion resistance and can maintain its reflective performance for a long time.

[0049] The protective coating 32 can be a silicon coating or a galvanized coating. The silicon coating can provide good high temperature resistance and excellent weather resistance. The galvanized coating can provide good physical protection and has a certain high temperature resistance, which is suitable for use in harsh environments. When the protective plate 3 is exposed to high temperature and harsh weather conditions for a long time, both the silicon coating and the galvanized coating can protect its surface from damage and maintain long-term stable performance.

[0050] It should be noted that: (1) the thickness of the protective plate 3 mentioned above can be controlled between 2 mm and 5 mm; (2) the structures of the connecting rod 1 55 and the connecting rod 2 56 are consistent, and the two are in mutual intersection. Example

When the protective plate 3 needs to be unfolded, the retracted length of the electric push rod 43 can be controlled according to the unfolding angle of the protective plate 3. The specific operation process is: the telescopic end of the electric push rod 43 is retracted, and the moving rack 44 is driven to move toward the PVT plate body 1 through the side plate 441. At this time, the gear 1 45 rotates counterclockwise, the gear 2 46 rotates clockwise, and the gear 3 47 rotates counterclockwise.

[0062] The sliding buckle 761 and the moving block 763 are provided with a detachable structure, and the connecting shaft 762 and the sliding buckle 761 are fixed by connecting bolts 765, thereby achieving structural stability and maintainability, so that subsequent maintenance operations can be performed more efficiently.

[0063] Specifically, the driving member 77 includes a C-shaped fixed seat 771, which is fixedly connected to the rear side of the upper surface of the beam 8, and a slide 772 is fixedly connected to the upper surface of the C-shaped fixed seat 771. Through grooves 7721 are penetrated on both sides of the slide 772, and the connecting shaft 762 is penetrated and connected inside the through groove 7721. A threaded rod 773 is rotatably connected inside the slide 772, and a threaded hole 7631 is penetrated on one side of the moving block 763.

[0064] The reduction motor 774 drives the threaded rod 773 to rotate through the coupling, and the moving block 763 will undergo a corresponding displacement change. This thread transmission method realizes the precise displacement adjustment of the moving block 763, and the structure is simple and reliable.

[0065] Specifically, an arc block 7722 is fixedly connected inside the sliding seat 772 and on the upper and lower sides of the through slot 7721.

[0068] The height of each group of support legs 9 can be adjusted according to actual installation requirements. By adjusting the relative position of the support column 93 inside the two groups of C-shaped plates 92, the overall height of the support legs 9 can be changed. After the adjustment is completed, the mounting bolt 94 is passed through the mounting hole 1 921 and the mounting hole 2 931 at the corresponding position. The operation is simple and convenient.

[0069] Working principle of the present invention:

[0070] The first step: when installing the PVT board body 1, first adjust the overall height of the support legs 9 according to the installation requirements. After the adjustment is completed, fix the base plate 91 to the installation ground.

[0071] Step 2: Place the PVT panel body 1 on the upper surface of the two sets of main support rods 51, first adjust the position between the left and right hook-type fixing seats 52 according to the horizontal length of the PVT panel body 1, and ensure that the hook-type fixing seats 52 can horizontally fix the PVT panel body 1. Then adjust the positions of the front and rear hook-type movable seats 53 according to the longitudinal length of the PVT panel body 1, and ensure that the hook-type movable seats 53 can vertically fix the PVT panel body 1.

[0072] Step 3: The wind speed detector 2 performs real-time wind speed detection on the position of the PVT panel body 1. When it is detected that the wind speed is too high, the reduction motor 774 will be controlled to run. The reduction motor 774 drives the threaded rod 773 to rotate through the coupling. At this time, the moving block 763 moves toward the fixed column 73, thereby driving the adjustment rod 75 to tilt until the PVT panel body 1 is adjusted from the inclined state to the horizontal state.

[0073] Step 4: When the protective plate 3 needs to be fastened (when the PVT panel body 1 absorbs solar energy and is in a saturated state; when there is no light at night; when encountering extreme weather such as hail or snow), the telescopic end of the electric push rod 43 will be controlled to extend, and the rotating shaft 34 located in the middle position will be driven to rotate, thereby driving the protective plate 3 to rotate and be fastened to the upper surface of the PVT panel body 1.

[0074] This completes the use process of a PVT thermal collector component with a protective structure.

[0075] It should be noted that the wind speed detector 2, electric push rod 43 and reduction motor 774 mentioned above are electrically connected to the control terminal and the PVT panel body 1. The control terminal is used to control the operation of the equipment, and the PVT panel body 1 is used to provide a power source to achieve full and effective utilization of solar energy.

[0076] At the same time, in actual applications, the control terminal can also be connected to the indoor control terminal to achieve remote control. The control terminal and the indoor control terminal are both conventional devices with control functions such as computers and PLCs.
