DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] See also Figure 1-5 , as shown in the figure, a photovoltaic support system with intelligent heat dissipation provided in this embodiment includes a server 101 and a photovoltaic support terminal 103, and the server 101 and the photovoltaic support terminal 103 are connected in communication via a communication network 102;

[0022] Specifically, the server 101 can communicate real-time data with the photovoltaic bracket terminal 103 through the communication network 102. Preferably, the communication network 102 can adopt wireless communication technologies such as cellular communication network 102, LoRaWAN, Sigfox, etc.; the server 101 can adopt a cloud server 101 or a local server 101, and this embodiment does not make specific restrictions.

[0023] The photovoltaic support terminal 103 is used to collect temperature data and water level data, the temperature data includes real-time temperature information of the photovoltaic component 2, and the water level data includes real-time water level information of cooling water; when the temperature data is higher than a preset temperature threshold, the photovoltaic support terminal 103 starts heat dissipation.

[0024] Specifically, the photovoltaic bracket terminal 103 may include a microcontroller, a wireless communication module, a sensor, etc. The microcontroller can collect the temperature data of the photovoltaic component 2 through the sensor and convert the data into a digital signal. The microcontroller can also calculate the temperature data and the preset temperature threshold, and then control the opening or closing of the heat dissipation work of the photovoltaic bracket terminal 103. The microcontroller can also communicate with the server 101 through the wireless communication module to send temperature data and water level data; wherein the sensor can specifically be a temperature sensor, such as a thermistor, PT100, infrared sensor, etc., for monitoring the real-time temperature information of the photovoltaic component 2, and can also include a water level sensor, such as a pressure sensor, a float switch, an ultrasonic sensor, etc., for monitoring the real-time water level information of the cooling water.

[0025] The photovoltaic support terminal 103 is also used to upload the temperature data and the water level data to the server 101 via the communication network 102 .

[0026] The server 101 is used to receive and store the temperature data and the water level data, and control the generation of high temperature warning and water level warning according to the temperature data and the water level data;

[0027] When the temperature data is in a state higher than the preset temperature threshold for a continuous period longer than a preset time threshold, the server 101 generates the high temperature warning and sends the high temperature warning to the staff through the communication network 102;

[0028] When the water level data is lower than a preset water level threshold, the server 101 generates the water level warning and sends the water level warning to the staff through the communication network 102 .

[0029] Specifically, when the temperature data remains above the preset temperature threshold for a preset time threshold, it indicates that the temperature of the photovoltaic component 2 is not effectively controlled, which may be caused by a failure in the heat dissipation work of the photovoltaic bracket terminal 103, and manual intervention and maintenance are required; when a water level warning occurs, it indicates that there is a shortage of cooling water and the staff needs to replenish it; the server 101 can send high temperature warnings and / or water level warnings to the staff's mobile phone terminals via the communication network 102.

[0030] The server 101 is further used to construct a prediction model based on the stored temperature data and the water level data, generate a pre-heating strategy through the prediction model calculation, and send the pre-heating strategy to the photovoltaic support terminal 103 through the communication network 102.

[0031] Specifically, the server 101 can use machine learning or deep learning algorithms, such as support vector machines (SVM), random forests, neural communication networks 102, etc., to build a prediction model based on temperature data, water level data and their historical data. The prediction model can predict the temperature trend of the photovoltaic component 2 in the future. Based on the calculation of the prediction model, a pre-heating strategy is generated. The pre-heating strategy may include starting the heat dissipation work in a certain time period in the future. The photovoltaic support terminal 103 is used to receive and execute the pre-heating strategy; the above process collects the temperature and cooling water conditions of the photovoltaic panel in real time through the sensor of the photovoltaic support terminal 103, and intelligently controls the opening and closing of the heat dissipation work of the photovoltaic component 2, which also provides basic data support for the server 101. At the same time, the server 101 uses machine learning algorithms to build a prediction model, predict the temperature trend of the photovoltaic component 2 in the future and make a pre-heating strategy, perform heat dissipation intervention in advance, improve the heat dissipation efficiency and reliability of the system, and provide a strong guarantee for the stable operation of the photovoltaic component 2.

[0032] Of course, a photovoltaic bracket terminal 103 can be specifically designed, as shown below:

[0033] Refer to the instruction manual Figure 2-5 ,like Figure 2 As shown, the photovoltaic support terminal 103 includes a structural support base 1 and an air cooling mechanism, and the air cooling mechanism includes a photovoltaic cell support plate 3 fixedly connected above the structural support base 1.

[0034] Specifically, the photovoltaic module 2 is installed above the photovoltaic cell support plate 3, and the photovoltaic module 2 is arranged in close contact with the photovoltaic cell support plate 3. Optionally, the temperature sensor in the photovoltaic bracket terminal 103 can be arranged at the connection between the photovoltaic module 2 and the photovoltaic cell support plate 3.

[0035] Combination Figure 3 As shown, the lower end surface of the photovoltaic cell support plate 3 is rotatably connected to the rotating blades 9 through a rotating shaft, and a rotating transmission wheel 10 is also fixedly connected to the rotating shaft. A rotating motor 12 is fixedly connected to one side of the photovoltaic cell support plate 3 on the structural support base 1, and a composite transmission wheel shaft 13 is fixedly connected to the output shaft of the rotating motor 12. The lower part of the composite transmission wheel shaft 13 is connected to the first drive through a power transmission belt 11. When the rotating motor 12 is started, it can drive the rotating blades 9 to rotate.

[0036] Specifically, when the photovoltaic bracket terminal 103 starts the heat dissipation work, the rotating motor 12 can be started. The rotation of the rotating motor 12 drives the composite transmission wheel shaft 13 to rotate, thereby driving the rotating transmission wheel 10 to rotate through the power transmission belt 11. The rotation of the rotating transmission wheel 10 will drive the rotating shaft and the rotating fan blades 9 on the rotating shaft to start rotating. During the rotation of the rotating fan blades 9, a rotating airflow will be generated to dissipate the heat generated by the photovoltaic component 2 through the photovoltaic cell support plate 3, thereby keeping the temperature of the photovoltaic component 2 below the preset temperature threshold.

[0037] It should be noted that when the photovoltaic assembly 2 generates electricity efficiently, the photovoltaic assembly 2 will generate a large amount of heat. At this time, the efficiency of the rotating fan blades 9 in removing heat through air convection may not be able to cope with the heat generation. Therefore, further specific designs can be made for this embodiment, as shown below:

[0038] Furthermore, it also includes a water cooling mechanism, which includes a cooling water storage container 5 . Specifically, the water level sensor in the photovoltaic support terminal 103 can be arranged on the inner wall of the cooling water storage container 5 .

[0039] The cooling water storage container 5 is fixedly connected to the structural support base 1 at the side of the photovoltaic cell support plate 3, the upper part of the cooling water storage container 5 is connected to the upper part of the photovoltaic cell support plate 3 through a liquid reflux pipe 4, the lower part of the cooling water storage container 5 is connected to the lower part of the photovoltaic cell support plate 3 through a liquid delivery pipe 6, and the interior of the photovoltaic cell support plate 3 is slidably connected with a piston push-pull plate 7.

[0040] Combination Figure 5 As shown, an auxiliary rotating wheel 16 is fixedly connected to the side of the photovoltaic cell support plate 3 near the rotating motor 12 through a support rod, and a rotary support ring sleeve 15 is sleeved between the auxiliary rotating wheel 16 and the upper part of the composite transmission wheel shaft 13. A rotating connecting rod 17 is rotatably connected to the outer wall of the rotating supporting ring sleeve 15, and the other end of the rotating connecting rod 17 is rotatably connected to a driving rod 8. The other end of the driving rod 8 passes through the side wall of the photovoltaic cell support plate 3 and is fixedly connected to the piston push-pull plate 7. The rotating connecting rod 17 can be rotated with the piston push-pull plate 7. As the rotary support ring sleeve 15 rotates back and forth on the periphery of the auxiliary rotating wheel 16 and the composite transmission wheel shaft 13, when the rotating connecting rod 17 moves toward the position of the photovoltaic cell support plate 3, the driving rod 8 pushes the piston push-pull plate 7 to move toward the position of the liquid return pipe 4 and the liquid delivery pipe 6; when the rotating connecting rod 17 moves away from the position of the photovoltaic cell support plate 3, the driving rod 8 pulls the piston push-pull plate 7 to move away from the position of the liquid return pipe 4 and the liquid delivery pipe 6.

[0041] Furthermore, one-way valves are provided at the connection points between the liquid reflux pipe 4 and the liquid delivery pipe 6 and the photovoltaic cell support plate 3 .

[0042] Specifically, the one-way valve at the liquid return pipe 4 only allows cooling water to flow from the photovoltaic cell support plate 3 into the liquid return pipe 4 , and the one-way valve at the liquid delivery pipe 6 only allows cooling water to flow from the liquid delivery pipe 6 into the photovoltaic cell support plate 3 .

[0043] It can be understood that when the photovoltaic bracket terminal 103 starts the heat dissipation work, the rotating motor 12 can be started. The rotating motor 12 can first drive the rotating fan blades 9 in the air cooling mechanism to rotate, generating air convection to take away part of the heat of the photovoltaic assembly 2 and the photovoltaic cell support plate 3; at the same time, the rotating motor 12 rotates to drive the composite transmission wheel shaft 13 to rotate, and also drives the rotary support ring sleeve 15 to rotate back and forth around the auxiliary rotating wheel 16 and the composite transmission wheel shaft 13, thereby driving the rotating connecting rod 17 to rotate synchronously;

[0044] When the rotating connecting rod 17 moves away from the position of the photovoltaic cell support plate 3, the driving rod 8 pulls the piston push-pull plate 7 to move away from the position of the liquid return pipe 4 and the liquid delivery pipe 6. At this time, negative pressure is gradually formed in the photovoltaic cell support plate 3, and under the joint action of the water pressure in the cooling water storage container 5, the cooling water in the cooling water storage container 5 flows into the photovoltaic cell support plate 3 through the liquid delivery pipe 6, so that the cooling water with a lower temperature can quickly absorb the heat of the photovoltaic module 2 and the photovoltaic cell support plate 3, so that the temperature of the photovoltaic module 2 drops rapidly;

[0045] When the rotating connecting rod 17 moves toward the location of the photovoltaic cell support plate 3, the driving rod 8 pushes the piston push-pull plate 7 to move toward the location of the liquid return pipe 4 and the liquid delivery pipe 6. At this time, the piston push-pull plate 7 gradually forms an extrusion force on the cooling water in the photovoltaic cell support plate 3. Under the action of the extrusion force, the one-way valve in the liquid delivery pipe 6 is closed, and the one-way valve in the liquid return pipe 4 is opened, so that the cooling water that has absorbed heat can flow back to the cooling water storage container 5 through the liquid return pipe 4;

[0046] In the above-mentioned embodiment, while the wind power mechanism takes away part of the heat of the photovoltaic module 2 and the photovoltaic cell support plate 3 through the rotating fan blades 9, it also drives the piston push-pull plate 7 in the water cooling mechanism to perform push-pull movements, so that the cooling water can circulate back and forth from the cooling water storage container 5 into the photovoltaic cell support plate 3, further quickly taking away the heat of the photovoltaic module 2 and the photovoltaic cell support plate 3, efficiently achieving the heat dissipation target of the photovoltaic bracket terminal 103, and ensuring that the photovoltaic system is in a reliable operating state.

[0047] It should be noted that in the actual operation of the above embodiment, cooling water will be continuously consumed during the operation of the system, resulting in a significant reduction in the heat dissipation efficiency of the photovoltaic bracket terminal 103. For this reason, the water cooling mechanism can be further specifically designed, as shown below:

[0048] More preferably, if Figure 4 As shown, a containing enclosure 24 is fixedly installed around the top of the cooling water storage container 5. Specifically, when it rains, the top surface of the cooling water storage container 5 and the containing enclosure 24 can form a water storage space on the top of the cooling water storage container 5 to store rainwater in this water storage space.

[0049] The top surface of the cooling water storage container 5 is also provided with mesh holes. Specifically, rainwater in the water storage space can flow into the cooling water storage container 5 through the mesh holes to supplement the consumed cooling water.

[0050] A position limiting rod 18 is fixedly connected to the inner bottom surface of the cooling water storage container 5, and a liquid level sensing float 19 is slidably sleeved on the outer wall of the position limiting rod 18. A right-angle toothed transmission bar 20 is fixedly connected to one side of the liquid level sensing float 19. The right-angle toothed transmission bar 20 passes through the top of the cooling water storage container 5 and is slidably connected to the cooling water storage container 5. A columnar transmission gear 21 meshing with the right-angle toothed transmission bar 20 is also rotatably connected to the inner wall of the cooling water storage container 5. A fluid blocking baffle 22 is slidably connected to the interior of the cooling water storage container 5 below the mesh.

[0051] Specifically, when the fluid blocking baffle 22 is located below the mesh, the mesh of the cooling water storage container 5 can be sealed, so that rainwater cannot flow into the interior of the cooling water storage container 5 .

[0052] The lower bottom surface of the fluid blocking baffle 22 is provided with a toothed bar meshing with the top of the columnar transmission gear 21, and the right-angled toothed transmission bar 20 meshes with the side of the columnar transmission gear 21, and the right-angled toothed transmission bar 20 and the fluid blocking baffle 22 are arranged in a staggered state. The top surface of the cooling water storage container 5 is located above the mesh and is also slidably installed with a T-shaped slide bar 23. One end of the T-shaped slide bar 23 passes through a through groove and is fixedly connected to the fluid blocking baffle 22. When the fluid blocking baffle 22 moves, it can drive the T-shaped slide bar 23 to slide in the through groove.

[0053] Specifically, a top cover matching the scraper rod is provided above the through groove to prevent the collected rainwater from flowing into the cooling water storage container 5 through the through groove.

[0054] It can be understood that the water storage space formed by the top surface of the cooling water storage container 5 and the containing enclosure 24 can collect a certain amount of rainwater on rainy days. When the photovoltaic bracket terminal 103 performs heat dissipation work, the water cooling mechanism will reciprocally suck the cooling water in the cooling water storage container 5 and discharge the cooling water. In this process, the water level in the cooling water storage container 5 will continue to rise or fall. When the cooling water is sucked into the photovoltaic cell support plate 3, the liquid level sensing float 19 drops due to the reduction of cooling water in the cooling water storage container 5. When the liquid level sensing float 19 drops, it will also drive the right-angle toothed transmission bar 20 to drop, thereby driving the meshing therewith. The columnar transmission gear 21 rotates, and the rotation of the columnar transmission gear 21 will drive the fluid blocking baffle 22 to slide to one side. When the fluid blocking baffle 22 slides to the extreme position, the rainwater at the bottom of the cooling water storage container 5 will enter the cooling water storage container 5 after being filtered through the mesh. At the same time, when the fluid blocking baffle 22 slides to one side, it will also synchronously drive the T-shaped slide bar 23 to move, so that the T-shaped slide bar 23 pushes away the impurities accumulated at the mesh, thereby avoiding the situation where the stored rainwater cannot enter the cooling water storage container 5, ensuring that the rainwater can replenish the cooling water in time, avoiding the need for staff to frequently add cooling water manually, and reducing maintenance costs.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
