Description

Technical Field

[0001] The invention relates to the technical field of photovoltaics, and in particular to a device for real-time acquisition of working temperature of a photovoltaic assembly. Background Art

[0002] A photovoltaic module refers to an indivisible smallest solar cell combination device that is packaged and internally connected and can provide direct current alone. It is also called a solar cell module. The photovoltaic module is the core part of the solar power generation system. Its main function is to convert solar energy into electrical energy, which can be sent to batteries for storage or directly drive the load. The working efficiency of photovoltaic modules is greatly affected by environmental factors, especially temperature. Excessively high operating temperatures may accelerate the aging of the modules, causing their performance to decline, and even cause failures or damage. In order to meet this challenge, it is particularly important to collect the working temperature of photovoltaic modules in real time. By monitoring the temperature, abnormal conditions can be discovered in time, and measures can be taken to adjust the operating status of the photovoltaic system to avoid the impact of overheating on the system.

[0003] After searching the patent with authorization announcement number CN218243428U, a real-time collection device for the working temperature of photovoltaic modules is disclosed, including an infrared temperature sensor, a pitch steering mechanism, a column, a device housing, and an infrared signal converter, a wireless communication module, a power supply and a data acquisition module arranged in the device housing.

[0004] The above patent discloses a real-time working temperature collection device for photovoltaic modules, which is connected to the shell through a column and uses a pitch steering mechanism to adjust the angle of the shell for temperature collection. However, the device cannot accurately adjust the radiation range of the infrared temperature sensor, which results in inaccurate temperature data collection of photovoltaic panels at the edge of the radiation angle. In addition, since the height of the device is fixed, it means that it cannot be flexibly adjusted according to different photovoltaic array layouts or installation environments, resulting in a relatively limited range of temperature collection. Therefore, it is necessary to design a real-time working temperature collection device for photovoltaic modules in view of the shortcomings of the prior art. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. 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.

[0030] Embodiment 1: A real-time acquisition device for the working temperature of a photovoltaic module, such as Figure 1-Figure 4 As shown, it includes a support column 1, a sliding rod 2 and an installation box 3. The support column 1 serves as a support carrier of the device. The sliding rod 2 is slidably installed in the upper inner wall of the support column 1. The installation box 3 is rotatably installed on the top of the sliding rod 2 through a mounting ring 302 fixed at the bottom. The installation partitions 301 are symmetrically arranged at the openings on both sides of the installation box 3; it also includes: multiple groups of infrared temperature sensors 4, which are symmetrically rotatably installed at the openings on both sides of the installation box 3 through mounting rods 401. The infrared temperature sensors 4 on each group of mounting rods 401 are independent of each other. The infrared temperature sensor 4 is provided with a data acquisition module inside, and The remote control center is contacted through the wireless communication module; the connecting block 402 is fixedly connected to the inner side of the partition of the installation partition 301, and the connecting block 402 is the rotation support point between two adjacent groups of installation rods 401; the swing component 5, the swing component 5 is used to adjust the collection angle of the infrared temperature sensor 4 up and down; the transmission member 6 is symmetrically arranged in the installation box 3, and the transmission member 6 is used to adjust the angle of multiple groups of infrared temperature sensors 4; the driving component 7 is arranged inside the installation box 3, and the driving component 7 is used to drive the installation box 3 to rise and fall, and at the same time, the infrared temperature sensor 4 can automatically and flexibly adjust the collection angle through the transmission member 6.

[0031] like Figure 3 and Figure 4 As shown, the swing assembly 5 includes: installation guide rods 501, which are symmetrically fixed to the top of the inner wall of the installation box 3; threaded blocks 502, which are the same in number as the infrared temperature sensors 4 and are slidably connected to the guide rods of the installation guide rods 501, and a slide groove is opened at one end of the threaded block 502 close to the infrared temperature sensor 4; a rotating disk 503, which is fixed to each group of installation rods 401, and a connecting rod 505 is eccentrically arranged on the rotating disk 503, and the connecting rod 505 is located in the slide groove of the corresponding threaded block 502; threaded rods 504, which are the same in number as the infrared temperature sensors 4 and are rotatably installed in the installation box 3, and each group of threaded rods 504 is threadedly connected to the corresponding threaded block 502, and the threaded block 502 is threadedly driven by the rotating threaded rods 504, so that the threaded block 502 can pull the infrared temperature sensor 4 up and down through the rotating disk 503 to change the angle.

[0032] like Figure 2-Figure 4 As shown, the transmission member 6 includes: a transmission rod 601, which is symmetrically rotatably installed inside the installation box 3, and the transmission rod 601 is provided with worms of the same number as the threaded rods 504; a worm wheel 602, which is installed at the lower part of each threaded rod 504, and the worm wheel 602 and the corresponding worm are meshed with each other; a volute spring 603, and a volute spring 603 for resetting is provided between the transmission rod 601 and the installation box 3; the transmission member 6 is used to synchronously drive the multiple threaded rods 504 to rotate, so that the multiple infrared temperature sensors 4 on the same side of the installation box 3 can adjust the angle in batches; the threads of the multiple sections of worms on the transmission rod 601 are cross-reversely arranged, and the unidirectional rotation of the transmission rod 601 can drive the corresponding worm wheel 602 to rotate through the synchronous meshing of worms in different directions. Since the threads between adjacent worms are opposite, the adjacent threaded rods 504 can rotate in opposite directions, and the rotating threaded rods 504 can be lifted and lowered by driving the thread block 502, so that the adjacent infrared temperature sensors 4 can adjust different sampling angles, thereby improving the accuracy of the infrared temperature sensor 4 in sampling the photovoltaic module.

[0033] like Figure 1 , Figure 5 and Figure 6 As shown, the driving assembly 7 includes: an electric push rod 701, which is installed inside the supporting column 1; a winding wheel 702, which is fixedly connected to the transmission rod 601; a fixed block 703, a certain gap is provided at the sliding connection between the supporting column 1 and the sliding rod 2, and the fixed block 703 is symmetrically fixedly installed at the gap on the inner wall of the supporting column 1; a pull rope 704, one end of which is wound around the winding wheel 702, and the other end is fixedly connected to the corresponding fixed block 703 on the same side. When the sliding rod 2 is pushed upward by the electric push rod 701 and the sliding rod 2 pushes the entire collection device to rise, the fixed block 703 on the supporting column 1 pulls the pull rope 704, so that the winding wheel 702 drives the corresponding transmission rod 601 to rotate, so that when the height of the collection device is adjusted, the infrared temperature sensor 4 can be automatically driven by the transmission rod 601 to adjust the sampling angle.

[0034] When using the present collection device to collect the working temperature of the photovoltaic module in real time, the electric push rod 701 is first activated. The push rod of the electric push rod 701 extends and pushes the sliding rod 2 to rise along the track inside the supporting column 1. As the sliding rod 2 rises, the sliding rod 2 will drive the installation box 3 installed on its top to rise together. At the same time, during the rising process of the sliding rod 2, the installation box 3 will pull the pull rope 704 upward. At this time, the fixed block 703 fixed on the inner wall of the supporting column 1 will pull the pull rope 704. After the pull rope 704 is pulled, it will drive the winding wheel 702 to rotate. Rotating the winding wheel 702 drives the transmission rod 601 to rotate by overcoming the elastic force of the volute spring 603. Since a plurality of reverse worms are arranged at intervals on the transmission rod 601, these worms will simultaneously mesh with the corresponding worm wheels 602 installed at the lower part of the threaded rod 504. At this time, the worm will synchronously drive the worm wheel 602 and the corresponding threaded rod 504 to rotate. The rotation of 4 will cause the adjacent threaded blocks 502 to slide in different directions along the installation guide rod 501. The up and down sliding of the threaded blocks 502 will synchronously pull the rotating disk 503 to deflect through the connecting rod 505. The deflected rotating disk 503 will eventually drive the corresponding installation rod 401 to rotate, so that the angle of the infrared temperature sensor 4 installed on the installation rod 401 changes, and temperature collection at different angles is realized. Therefore, whenever the collection height of the entire device changes, the angle of the infrared temperature sensor 4 will also be automatically adjusted to expand the collection and scanning angle of the photovoltaic module, so that the infrared temperature sensor 4 can scan the working temperature of different positions of the photovoltaic module in real time, and transmit the collected temperature data to its internal data collection module, and then send it to the control center via the wireless communication module. When the temperature value is abnormal, the monitoring personnel of the control center will promptly arrange on-site maintenance personnel to conduct inspection and maintenance.

[0035] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 7 and Figure 8 As shown, a cleaning component 8 is also included, and the cleaning component 8 is used to clean the infrared temperature sensor 4. The cleaning component 8 includes: a mounting block 801, which is symmetrically slidably installed at the openings on both sides of the mounting box 3; a cleaning block 802, which is arranged on the side of the mounting block 801 close to the infrared temperature sensor 4; a screw rod 803, which is rotatably arranged at the openings on both sides of the mounting box 3, and the screw rod 803 is threadedly connected to the mounting block 801 on the same side; a motor I 804, which is installed at the frame of the mounting partition 301, and the output shaft of the motor I 804 is connected to the screw rod 803, and the screw rod 803 is driven to rotate by the motor I 804, so that the mounting block 801 can clean the infrared temperature sensor 4 through the cleaning block 802 thereon.

[0036] like Figure 1 and Figure 8As shown, a rotating assembly 9 is provided between the mounting ring 302 and the sliding rod 2, and the rotating assembly 9 includes: a motor II 901, mounted on one side of the mounting ring 302; a gear 902, mounted on the output shaft of the motor II 901; a gear ring 903, fixedly arranged on the outer wall of the sliding rod 2, the gear 902 and the gear ring 903 are meshed with each other, and the gear 902 is driven to rotate by the motor II 901. After the gear 902 meshes with the gear ring 903, the motor II 901 will rotate around the gear ring 903, thereby driving the mounting ring 302 and the collection device thereon to deflect the angle, so that the collection device can adapt to the temperature collection requirements of photovoltaic components at different angles.

[0037] like Figure 1 and Fig. 9 As shown, a reinforcement component 10 is provided at the lower part of the support column 1, and the reinforcement component 10 includes: a fixing ring 101, fixedly mounted on the support column 1; a plurality of support plates 102, circumferentially hinged to the periphery of the fixing ring 101; a sliding block 103, slidably mounted on the outer wall of the support column 1; a connecting rod 104, the number of which is the same as the support plate 102 and one end of which is circumferentially hinged to the periphery of the sliding block 103, and the other end of the connecting rod 104 is hinged to the connecting port at the lower middle part of the support plate 102; a cylinder 105, symmetrically mounted on the outer side of the support column 1, the telescopic rod of the cylinder 105 is connected to the sliding block 103, and the sliding block 103 is pushed and pulled up and down by the cylinder 105, so that the sliding block 103 can push and pull the support plate 102 through the plurality of connecting rods 104 hinged thereon, so that the support plate 102 can be stored and expanded with the hinge point on the fixing ring 101 as the center, thereby facilitating the support and reinforcement of the support column 1.

[0038] like Figure 1 and Figure 2 As shown, the installation box 3 is provided with a constant temperature component 11, and the constant temperature component 11 includes: a temperature adjustment frame 111, which is installed on the installation box 3, and the temperature adjustment frame 111 is installed in a U shape and fits on the top and side walls of the installation box 3. The temperature adjustment frame 111 has good thermal conductivity and its interior is used to store phase change materials for energy storage and temperature adjustment. The top of the temperature adjustment frame 111 is provided with a filling port 112 for filling the phase change material; an accordion cover 113, which is installed and covered on each infrared temperature sensor 4, and the accordion cover 113 blocks the opening of the infrared temperature sensor 4 on the installation box 3. The accordion cover 113 is used to assist in heat preservation and heat insulation. By adding phase change materials (paraffin, salt hydrate) into the temperature control frame 111, the phase change material changes from solid to liquid under high temperature conditions during the day, thereby absorbing the heat conducted from the installation box 3 to the temperature control frame 111. At night, under low temperature conditions, the phase change material changes from liquid to solid, and conducts heat to the installation box 3. The accordion cover 113 covers the opening of the installation box 3 to provide heat preservation and heat insulation, so that the electronic components in the installation box 3 are maintained in a relatively constant temperature state, thereby increasing the service life of the electronic components.

[0039] When the collection device is installed on the ground through the support column 1 for use, the two cylinders 105 are activated synchronously, and the upward movement of the telescopic rod of the cylinder 105 will drive the sliding block 103 to slide up at the side wall of the support column 1. The sliding block 103 that slides up will synchronously pull the support plate 102 through multiple circumferential connecting rods 104, so that the multiple support plates 102 are changed from a state close to the support column 1 to a state of being stretched outward, so that the multiple support plates 102 are circumferentially supported at the peripheral position of the support column 1, thereby improving the installation stability of the collection device. When the infrared temperature sensor 4 collects the data at the upper and lower collection angles, the motor II 901 can be enabled, and the output shaft of the motor II 901 will drive the gear 902 to rotate, and the rotating gear 902 will mesh with the gear ring 903. Under the meshing action of the gear ring 903, the gear 902 can mesh and rotate around the gear ring 903, so that the motor II 901 can drive the mounting box 3 and the infrared temperature sensor 4 thereon to rotate left and right through the mounting ring 302, so that the infrared temperature sensor 4 can meet the real-time collection of the working temperature of the photovoltaic components at different angles. When it is necessary to clear When cleaning the infrared temperature sensor 4, the motor I 804 is started, and the output shaft of the motor I 804 will drive the screw rod 803 to rotate. The screw rod 803 rotates and drives the mounting block 801 to slide at the openings on both sides of the mounting box 3 through the thread. The mounting block 801 drives the cleaning block 802 to move and cleans the surface of the cleaning infrared temperature sensor 4 to ensure the accuracy of temperature collection. When the outside temperature rises during the day, the phase change material in the temperature adjustment frame 111 will absorb heat and change from solid to liquid. This process absorbs a large amount of latent heat and slows down the temperature rise in the mounting box 3. At night, as the ambient temperature drops, the phase change material begins to release the previously stored heat and re-solidifies from liquid to solid, thereby delaying the decrease in the temperature in the box. In addition, the accordion cover 113 covering each infrared temperature sensor 4 can not only prevent external dust from entering the device, but also provide additional thermal insulation effects, especially in low temperature environments, which helps to reduce heat loss, so that the entire system can effectively keep the electronic components in the mounting box 3 at a relatively constant and suitable working temperature, thereby extending its service life.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
