Description

Technical Field

[0001] The invention relates to a photovoltaic component inclination detection device, belonging to the technical field of photovoltaics. Background Art

[0002] Photovoltaic modules, also known as solar panels, are the core and soul of solar power generation systems. Their main function is to convert the sun's rays into electrical energy, or store them in batteries for emergency use, or directly drive the load to work. In order to maximize the absorption of sunlight, photovoltaic modules are usually installed in locations such as rooftops that can fully access sunlight. However, due to differences in the angle of sunlight in different regions, strict requirements are placed on the installation angle to ensure that photovoltaic modules can generate electricity efficiently. Therefore, during the installation and commissioning of photovoltaic modules, an inclination detection device is generally used to detect the installation angle of the photovoltaic modules; At present, inclination detection devices mostly use a pendant structure in conjunction with an angle ruler for measurement. At the same time, in order to ensure the stability of the device for detection, an elastic or threaded clamp structure is generally used to firmly connect the device to the photovoltaic module. However, in order to ensure the accuracy of the installation angle of the photovoltaic module, it is usually necessary to detect multiple positions on the photovoltaic module. When changing the detection position, the operator often manually disassembles and reinstalls the device. This process is not only cumbersome and time-consuming, but also easily causes the device to be misaligned when reinstalled, resulting in a high probability of error in the detected inclination data due to factors such as misalignment. Frequent manual operations will also increase labor intensity, which will affect the detection effect and accuracy. Summary of the invention

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] Embodiment 1: As shown in Figures 1 - 9As shown in the figure, a photovoltaic module inclination detection device is provided, which includes a housing 1. Two transparent plates 7 extending to the inner wall of the housing 1 and having a semi-circular appearance and provided with scale lines are respectively inlaid on the front and rear ends of the housing 1. Through the transparent plates 7, the inclination data is indicated. The third shaft 8 located above the transparent plates 7 is rotatably connected inside the housing 1. Through the third shaft 8, a mounting carrier is provided for the transparent tube 82. Then, the transparent tube 82 arranged vertically between the two transparent plates 7 is arranged at the lower end of the third shaft 8. Through the transparent tube 82, a mounting carrier is provided for components such as the counterweight 9. The indicating rod 81 arranged along the length direction of the transparent tube 82 is installed inside the transparent tube 82. Through the indicating rod 81, it is used to indicate on the scale lines of the transparent plates 7. Then, the counterweight 9 located below the transparent plates 7 is installed at the lower end of the transparent tube 82. Through the counterweight 9, the transparent tube 82 is caused to move; The horizontal part of the mounting plate 2 with an L-shaped cross-section is arranged at the lower end of the housing 1. Through the housing 1, a mounting carrier is provided for components such as the transparent plates 7. Two first shafts 5 are symmetrically and rotatably connected to the rear end of the vertical part of the mounting plate 2. Through the first shafts 5, the upper rollers 51 are rotatably connected to the mounting plate 2. Then, two upper rollers 51 located below the horizontal part of the mounting plate 2 are respectively installed at the rear ends of the two first shafts 5. The two upper rollers 51 are used in cooperation to assist the movement of components such as the mounting plate 2. Two second shafts 6 are symmetrically and rotatably connected to the rear end of the moving plate 4 directly below the vertical part of the mounting plate 2. Through the second shafts 6, a mounting carrier is provided for the lower rollers 61. Two lower rollers 61 located directly below the upper rollers 51 are respectively arranged at the rear ends of the two second shafts 6. The two lower rollers 61 are used in cooperation to cause the movement of components such as the moving plate 4; The fixed part of the driving device with an output shaft connected to one of the second shafts 6 is arranged at the front end of the moving plate 4. Through the driving device, the connected second shaft 6 is driven to rotate. The driving device can adopt a servo motor 3. The screw rod 21 located in front of the housing 1 and having its upper end passing through the mounting plate 2 and being threadedly connected to the mounting plate 2 is rotatably connected to the middle position of the upper end of the moving plate 4. Through the screw rod 21, the moving plate 4 moves up and down. Then, two round rods 22 located between the two first shafts 5 and on the left and right sides of the screw rod 21 and having their upper ends passing through the mounting plate 2 and being slidably connected to the mounting plate 2 are symmetrically arranged at the upper end of the moving plate 4. The two round rods 22 are used in cooperation to guide the movement of the moving plate 4; The synchronous belt 62 located in front of the lower roller 61 is arranged at the rear side of the moving plate 4. Through the synchronous belt 62, the two gears 63 are synchronously rotated. Two gears 63 located at the outer ends of the two second shafts 6 and on the rear side of the moving plate 4 are respectively engaged with the left and right inner walls of the synchronous belt 62. Through the gears 63, the other second shaft 6 is rotated. Then, the handle integrated with the housing 1 is arranged at the upper end of the housing 1. Through the handle, it is convenient to carry components such as the housing 1; The two lighting lamps 13 with their emission surfaces arranged towards the transparent tube 82 on the left and right sides of the counterweight 9 are symmetrically arranged on the inner bottom end of the housing 1. The two lighting lamps 13 are used in cooperation to facilitate the observation of the indicating rod 81 in the transparent tube 82. The power source 14 located outside the lighting lamps 13 and electrically connected to the two lighting lamps 13 and the driving device respectively is installed on the inner bottom end of the housing 1. Through the power source 14, electrical energy is provided for the lighting lamps 13 and the driving device. Heat dissipation grooves extending to the inner wall of the housing 1 are formed by inward depressions on both left and right end faces of the housing 1. Through the heat dissipation grooves, the components inside the housing 1 are dissipated heat.

[0020] During use, first place the two upper rollers 51 on the upper end of the photovoltaic module, and at the same time place the two lower rollers 61 on the lower side of the photovoltaic module. Then rotate the screw rod 21. Since the screw rod 21 is threadedly connected to the mounting plate 2, when the screw rod 21 rotates, the screw rod 21 moves upward, and then the moving plate 4 moves upward, so that the two lower rollers 61 move upward and contact the lower end of the photovoltaic module, and then clamp on the photovoltaic module; At this time, under the action of the weight of the counterweight 9 itself, the third shaft 8 rotates, and then the indicating rod 81 and the transparent tube 82 are in a vertical state. At this time, the indicating rod 81 coincides with a certain position on the scale line of the transparent plate 7. Then read the angle marked on the scale line at this position, which is the inclination angle data of the first group of photovoltaic modules; Then start the servo motor 3, which drives a corresponding second shaft 6 to rotate, and then the corresponding gear 63 rotates. With the assistance of the synchronous belt 62, the other gear 63 rotates, so that the two second shafts 6 rotate synchronously, and then the two lower rollers 61 rotate. Thus, with the assistance of the two upper rollers 51, components such as the mounting plate 2 and the housing 1 are moved along the photovoltaic module to a suitable position. Then, under the weight of the counterweight 9, the indicating rod 81 coincides with a certain position on the scale line of the transparent plate 7. Read the angle marked on the scale line at this position again, which is the inclination angle data of the second group of photovoltaic modules; In the same way as the above steps, the inclination angle detection is carried out at multiple positions on the photovoltaic module, and then the multiple groups of detected inclination angle data are compared and calculated, so as to obtain the inclination angle of the photovoltaic module, realizing the mechanical multi-point detection operation of the photovoltaic module, effectively reducing the probability of the components such as the housing 1 being displaced due to manually changing the detection position, effectively reducing the probability of errors in the detected inclination angle data due to factors such as displacement, effectively reducing the detection time and labor intensity, and effectively ensuring the detection effect and accuracy; When reading the angle data marked on the detected scale line, connect the circuit between the power source 14 and the two lighting lamps 13, so that the two lighting lamps 13 irradiate the transparent tube 82, realizing the auxiliary observation of the indicating rod 81, effectively reducing the probability of interference with data reading due to factors such as shadows generated inside the housing 1, and effectively ensuring the detection effect.

[0021] Embodiment 2: A counterweight 9, a third shaft 8, an indicating rod 81, and a transparent tube 82 are used to detect the inclination angle of the photovoltaic module. Through a servo motor 3, two first shafts 5, two second shafts 6, two gears 63, a synchronous belt 62, two lower rollers 61, and two upper rollers 51, components such as the mounting plate 2 and the housing 1 can move along the photovoltaic module, thereby completing the mechanical multi-point detection operation on the photovoltaic module. However, during the movement of these components, components such as the indicating rod 81 and the transparent tube 82 are prone to jitter, resulting in the need to wait for the indicating rod 81 to return to a stationary state when reading data, which undoubtedly increases the overall detection time.

[0022] To solve the above problems, as Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10 shown, two arc-shaped plates 11 that are respectively slidably connected to the front and rear ends of the transparent tube 82 and are located outside the transparent plate 7 and above the counterweight 9 are respectively arranged on the front and rear inner walls of the housing 1. The two arc-shaped plates 11 are used in combination. On the one hand, they limit the front and rear positions of the transparent tube 82, and on the other hand, they provide a processing carrier for the first groove 12. First grooves 12 are recessed upward on the lower end faces of the two arc-shaped plates 11. Through the first grooves 12, the movement of the rolling members is guided; Two second grooves 91 located on the front and rear sides of the transparent tube 82 are recessed downward on the upper end face of the counterweight 9. Through the second grooves 91, an installation space is provided for components such as the movable plate 93. Two movable plates 93 are respectively slidably connected in the two second grooves 91. Through the movable plate 93, an installation carrier is provided for the rolling members. The rolling members that are respectively slidably connected to the two second grooves 91 are respectively arranged on the upper ends of the two movable plates 93. Through the rolling members, the counterweight 9 can move effectively. The rolling members can adopt bull's-eye universal balls 94. Then, second elastic members 92 are arranged between the lower ends of the movable plates 93 and the inner bottom ends of the second grooves 91. Through the second elastic members 92, an extrusion force is applied to the movable plates 93. The second elastic members 92 can adopt springs.

[0023] During use, first use the screw rod 21 to move the moving plate 4 upward, so that the two upper rollers 51 and the two lower rollers 61 clamp the photovoltaic module. Then, through the counterweight 9, the third shaft 8, the indicating rod 81, the transparent tube 82 and the scale line on the transparent plate 7, the inclination data of the first group of photovoltaic modules is detected. Then, use the servo motor 3, the two first shafts 5, the two second shafts 6, the two gears 63, the synchronous belt 62, the two lower rollers 61 and the two upper rollers 51 to move the mounting plate 2, the housing 1 and other components along the photovoltaic module to a suitable position. Then, through the counterweight 9, the third shaft 8, the indicating rod 81, the transparent tube 82 and the scale line on the transparent plate 7, the inclination data of the second group of photovoltaic modules is detected again. In the same way as the above steps, the inclination detection is carried out at multiple positions on the photovoltaic module; During the process of using the servo motor 3 to move the mounting plate 2, the housing 1 and other components, the two second elastic members 92 are in a compressed state, so that the two second elastic members 92 have elastic force. Under the action of the elastic force of the second elastic members 92, an upward extrusion force is applied to the movable plate 93, so that the rolling ball part of the bull's-eye universal ball 94 is in close contact with the first groove 12, realizing elastic extrusion treatment of the counterweight 9, effectively reducing the probability of jitter and other problems of the structure formed by the third shaft 8, the transparent tube 82, the indicating rod 81 and the counterweight 9 due to movement operations, effectively reducing the probability of waiting required for reading due to factors such as jitter, effectively reducing the detection time, and effectively ensuring the detection effect.

[0024] Embodiment 3: Use the screw rod 21, the two first shafts 5, the two second shafts 6, the two lower rollers 61 and the two upper rollers 51 to clamp and install the mounting plate 2, the housing 1 and other components with the photovoltaic module. On this basis, with the help of the counterweight 9, the third shaft 8, the indicating rod 81 and the transparent tube 82, the inclination of the photovoltaic module is detected. In addition, through the servo motor 3 and in cooperation with the two gears 63 and the synchronous belt 62, the two first shafts 5, the two second shafts 6, the two lower rollers 61 and the two upper rollers 51 are moved, so that the mounting plate 2, the housing 1 and other components can move smoothly along the photovoltaic module, thus completing the mechanical multi-point detection operation on the photovoltaic module. However, in the actual operation process, installation deviation and other phenomena are likely to occur during the installation between these components and the photovoltaic module, which may cause a relatively high probability of detachment of the mounting plate 2, the housing 1 and other components during the subsequent movement. And due to factors such as movement vibration during the movement, the mounting plate 2, the housing 1 and other components are prone to oblique displacement, resulting in deviation and other phenomena when the mounting plate 2, the housing 1 and other components move to the detection position on the photovoltaic module, resulting in a relatively high probability of error in the detected inclination data.

[0025] To solve the above problems, as Figure 11 and Figure 12As shown in the figure, a plurality of installation grooves 27 are formed by forward recesses on the rear end surface of the vertical portion of the installation plate 2. The installation grooves 27 are located between the upper roller 51 and the lower roller 61, outside the screw rod 21, and outside the round rod 22. A plurality of extrusion blocks 28 extending from the rear side of the installation grooves 27 are respectively slidably connected in the plurality of installation grooves 27. Through the extrusion blocks 28, an installation carrier is provided for the cylinder 29, and a plurality of cylinders 29 located in the installation grooves 27 are respectively arranged at the middle positions of the front ends of the plurality of extrusion blocks 28. Through the cylinder 29, an installation carrier is provided for the second contact block 25. Then, a plurality of first elastic members 26 located outside the cylinder 29 are arranged between the front end of the extrusion block 28 and the front inner wall of the installation groove 27. Through the first elastic member 26, the extrusion block 28 is returned to its original position. The first elastic member 26 can be a spring; A plurality of second contact blocks 25 electrically connected to the power source 14 are respectively embedded on the front ends of the plurality of cylinders 29, and a plurality of first contact blocks 24 located directly in front of the second contact blocks 25 are respectively embedded on the front inner walls of the plurality of installation grooves 27. The first contact block 24 and the second contact block 25 are used in cooperation to electrically connect the indicator lamp 23 and the power source 14. Then, a plurality of indicator lamps 23 extending from the front side of the installation plate 2 are respectively arranged on the front ends of the plurality of first contact blocks 24, and the plurality of first contact blocks 24 are respectively electrically connected to the plurality of indicator lamps 23.

[0026] During use, first, the screw rod 21 is used to move the moving plate 4 upward, so that the two upper rollers 51 and the two lower rollers 61 clamp the photovoltaic module. At this time, the corresponding side end of the photovoltaic module is in mutual contact with the rear end of the vertical portion of the installation plate 2, and a plurality of extrusion blocks 28 respectively move forward along the plurality of installation grooves 27, thereby compressing the plurality of first elastic members 26 and causing the first elastic members 26 to generate elastic force; At the same time, the cylinder 29 and the second contact block 25 move forward, and the second contact block 25 is in mutual contact with the corresponding first contact block 24, so that the circuit between the indicator lamp 23 and the power source 14 is turned on, and then the indicator lamp 23 emits indicator light, realizing the positioning installation between components such as the installation plate 2 and the housing 1 and the photovoltaic module, effectively reducing the probability of falling off and the like during subsequent movement due to factors such as installation deviation, and effectively ensuring the detection effect and service life; Then, through the counterweight 9, the third shaft 8, the indicating rod 81, the transparent tube 82, and the scale line on the transparent plate 7, the inclination angle data of the first group of photovoltaic modules are detected. Then, by using the servo motor 3, the two first shafts 5, the two second shafts 6, the two gears 63, the synchronous belt 62, the two lower rollers 61, and the two upper rollers 51, components such as the installation plate 2 and the housing 1 are moved along the photovoltaic module to a suitable position. Then, through the counterweight 9, the third shaft 8, the indicating rod 81, the transparent tube 82, and the scale line on the transparent plate 7, the inclination angle data of the second group of photovoltaic modules are detected again. In the same steps as above, the inclination angle detection is performed at multiple positions on the photovoltaic module; During the process of moving components such as the mounting plate 2 and the housing 1 by using the servo motor 3, if there is a deviation or other phenomenon between components such as the mounting plate 2 and the housing 1 and the photovoltaic module, a gap will appear in a certain area between the rear end of the vertical portion of the mounting plate 2 and the side end of the photovoltaic module. As a result, the extrusion block 28 in this gap will move backward under the elastic force of the corresponding first elastic member 26, causing the cylinder 29 and the second contact block 25 to move backward, and then separating the second contact block 25 from the corresponding first contact block 24, thereby disconnecting the circuit between the corresponding indicator light 23 and the power supply 14, and further causing the light of the indicator light 23 to disappear. When the light of a certain indicator light 23 disappears, it reminds that there is a deviation or other phenomenon between components such as the mounting plate 2 and the housing 1 and the photovoltaic module, realizing early warning of the installation positions of components such as the mounting plate 2 and the housing 1 in the detection position, effectively reducing the probability of error in the detected inclination data of components such as the mounting plate 2 and the housing 1 due to deviation and other factors on the detection position of the photovoltaic module, and effectively ensuring the detection effect and accuracy.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
