Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic technology, and specifically relates to a photovoltaic control device with a sensor protection function and a protection method thereof. Background Art

[0002] A photovoltaic control device (also known as a photovoltaic controller or a solar controller) is a core device in a solar power generation system, mainly used to manage the energy transmission between photovoltaic modules and storage batteries to ensure the efficient and safe operation of the system. Through intelligent charge and discharge management, dynamic power optimization, and multi-level protection mechanisms, the photovoltaic control device becomes the key to the efficient and stable operation of the solar system. The photovoltaic control device is usually connected to the photovoltaic panel through connecting wires for the control of the photovoltaic panel, and at the same time, sensors are installed on the photovoltaic control device for monitoring and control.

[0003] Conventional photovoltaic control devices need to be connected to photovoltaic panels and monitor the external environment, so they are usually installed outdoors for use. However, due to the harsh outdoor environment, when encountering strong winds or bad weather, the sensor part is easily damaged because it is exposed to the external environment.

[0004] At the same time, the photovoltaic control device is connected to the photovoltaic panel through connecting wires. However, in the face of bad weather, such as strong winds or severe convective weather, the connecting wires are easily detached from the terminal blocks due to external forces, resulting in the failure of the photovoltaic panel array, which urgently needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to provide a photovoltaic control device with a sensor protection function and a protection method thereof to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A photovoltaic control device with a sensor protection function includes a controller body. Plug terminals are equidistantly and fixedly installed at positions near the bottom of the front surface of the controller body. A sensor matrix is equidistantly and fixedly installed at positions near the top of the front surface of the controller body. An adjustment component is installed on the top of the front surface of the controller body through a base. The front end of the adjustment component is fixedly communicated with a gas collection component. Longitudinal guide rails are fixedly installed on both the left and right sides of the front surface of the controller body. A protection cover plate is movably clamped between the two longitudinal guide rails. A linkage component is installed at the top of the protection cover plate, and the other end of the linkage component is connected to the longitudinal guide rail. Limit snap rings are provided above the plug terminals. When the protection cover plate moves up and down relative to the longitudinal guide rail and the adjustment component is in the initial state, the protection cover plate is located below the front surface of the sensor matrix.

[0007] In the initial state, the protective cover plate is located below the front of the sensor matrix. At this time, the external environment can be monitored through the sensor matrix, and at the same time, the external connecting wire can be plugged into the plug terminal, and the distance between the limit snap ring and the plug terminal is the maximum value, completing the control process of the photovoltaic panel under normal conditions.

[0008] As a further technical solution of the present invention, the air collecting component includes an air collecting hood, the rear end of the air collecting hood is fixedly communicated with an air collecting tank, and the rear end of the air collecting tank is communicated with the front end of the adjusting component.

[0009] As a further technical solution of the present invention, a main shaft is movably connected inside the air collecting tank, and an impeller located inside the air collecting tank is fixedly sleeved on the outer side of the main shaft.

[0010] As a further technical solution of the present invention, micro generators are installed at both the left and right ends of the air collecting tank, and one end of the main shaft penetrates through one side of the air collecting tank and is connected to the input end of the micro generator.

[0011] When encountering strong convection or strong wind weather, at this time, the high-speed air outside can enter the inside of the air collecting tank after converging through the air collecting hood, and can push the impeller to rotate. At this time, the main shaft rotates accordingly and transmits the power to the micro generator. At this time, the micro generator generates an induced current accordingly. At the same time, the micro generator can be connected to an external alarm. When the induced current generated by the micro generator reaches the set threshold, the external alarm is turned on to complete the automatic early warning of extreme weather.

[0012] By utilizing the high-speed wind force generated by extreme weather, the rotation of the impeller is realized through the flow of air, and the change of the induced current is realized through the change of the wind force. Finally, the automatic alarm is realized, so that the device can perform automatic early warning in extreme weather, reminding the staff to carry out maintenance and reducing the damage probability of the photovoltaic array in extreme weather.

[0013] As a further technical solution of the present invention, the adjusting component includes an adjusting pipe, the outer side of the adjusting pipe is connected to the machine base, the front end of the adjusting pipe is communicated with the rear end of the air collecting tank, and a piston plate is movably sleeved inside the adjusting pipe.

[0014] As a further technical solution of the present invention, a piston rod is fixedly connected to the rear end of the piston plate, the rear end of the piston rod penetrates through the rear end of the adjusting pipe and is connected to the linkage component, and a limit spring is movably sleeved on the outer side of the piston rod. The left and right ends of the limit spring are respectively connected to one end of the piston plate and one end of the inner cavity of the adjusting pipe.

[0015] Meanwhile, when the high-speed air is led out from the air collecting tank, air can enter the interior of the regulating pipe and exert a thrust on the piston plate. At this time, the limiting spring is compressed accordingly, driving the piston plate and the piston rod to displace backward. When the air pressure is high enough, the limiting spring can be compressed to the extreme state, and at this time, the piston rod displaces to the rearmost end.

[0016] As a further technical solution of the present invention, the linkage assembly includes heightening frames. The number of the heightening frames is two and they are installed on the left and right sides of the top end of the protective cover plate. One side of the top end of each heightening frame is fixedly installed with a first fixing seat. One end of the first fixing seat away from the heightening frame is movably connected with a connecting rod through a rotating shaft, and one end of the connecting rod away from the first fixing seat is movably connected with a second fixing seat through a rotating shaft.

[0017] As a further technical solution of the present invention, the linkage assembly further includes a linkage frame. The left and right ends of the inner side surface of the linkage frame are connected to the second fixing seats, and the middle part of the inner side surface of the linkage frame is connected to the piston rod. When the limiting spring is in the extreme compression state, the linkage frame moves to the rightmost side and the protective cover plate moves to the front of the sensor matrix.

[0018] When the piston rod displaces to the rearmost end, it can drive the linkage frame to displace to the rearmost end at this time. At this time, the connecting rod deflects obliquely upward accordingly, and at the same time exerts a pulling force on the bottom heightening frame, and under the guiding action of the longitudinal guide rail and the protective cover plate, drives the protective cover plate to displace upward until the protective cover plate displaces to the front of the sensor matrix. At this time, the protective cover plate can completely block the sensor matrix, completing the active protection of the sensor matrix and reducing the damage of the sensor matrix.

[0019] By utilizing the high-speed air in extreme weather, taking the high-speed air as power, and using the cooperation between the regulating component and the linkage component, the active rising of the protective cover plate is realized. The whole rising process is automatically completed, that is, the active protection of the sensor matrix in strong wind weather is realized. The whole protection process can be automatically completed without manual control, which can effectively reduce the damage probability of the sensor matrix in extreme weather and improve the service life.

[0020] As a further technical solution of the present invention, an extension frame is fixedly installed at the bottom end of the linkage frame, and a mounting plate is fixedly installed at the bottom end of the extension frame. The top end of the limiting snap ring is connected to the bottom end of the mounting plate.

[0021] Meanwhile, in extreme weather, since the backward displacement of the linkage frame can synchronously drive the extension frame to displace backward, when the extension frame displaces backward, it synchronously drives the mounting plate and the limiting snap ring to displace backward. At this time, the limiting snap ring displaces toward the direction close to the plug terminal, pulling the external connecting wire at the bottom toward the direction close to the plug terminal. This avoids the phenomenon of the external connecting wire falling off due to external force in extreme weather.

[0022] Active protection is achieved by utilizing the automatic rising of the protective cover during extreme weather, and the automatic displacement of the limit retaining ring is synchronously realized, so that the plug-in terminal and the external connecting wire are kept tightly connected during extreme weather, ensuring that the device can not only achieve active protection of the sensor matrix during extreme weather, but also avoid the problem of the photovoltaic array failure caused by the falling off of the external connecting wire, further improving the stability of the device when used in harsh environments.

[0023] A protection method for a photovoltaic control device with a sensor protection function includes the following steps:

[0024] S1: When the device is in a normal state, the protective cover is located below the front of the sensor matrix, and the distance between the limit retaining ring and the plug-in terminal is the maximum value. At this time, the external connecting wire is plugged into the plug-in terminal, and the external environment is monitored through the sensor matrix;

[0025] S2: When encountering strong convective weather, the wind force increases significantly at this time. The wind force converges through the air collecting hood and enters the inside of the air collecting tank, and drives the impeller to rotate. At this time, the main shaft rotates accordingly, and at the same time, the power is transmitted to the micro generator. The magnitude of the wind force is judged through the current of the micro generator to complete the early warning;

[0026] S3: At the same time, high-pressure air enters the inside of the adjusting pipe and pushes the piston plate to displace backward. At this time, the limit spring can be compressed. When the limit spring is compressed to the limit position, the linkage frame displaces to the rearmost end at this time, and a pulling force is applied to the protective cover through the connecting rod. At this time, the protective cover displaces upward accordingly until it displaces directly in front of the sensor matrix to block and protect the sensor matrix;

[0027] S4: When the linkage frame displaces backward, the extension frame displaces backward accordingly, drives the mounting plate and the limit retaining ring to displace backward, and presses the external connecting wire to keep it tightly connected to the plug-in terminal.

[0028] The beneficial effects of the present invention are as follows:

[0029] (1) By utilizing the high-speed air during extreme weather, taking the high-speed air as power, and using the cooperation between the adjusting component and the linkage component, the present invention realizes the active rising of the protective cover, and the entire rising process is automatically completed, that is, the active protection of the sensor matrix during strong wind weather is realized, and the entire protection process can be automatically completed without manual control, which can effectively reduce the damage probability of the sensor matrix during extreme weather and improve the service life.

[0030] (2) The active protection achieved by the automatic rising of the protective cover plate during extreme weather in the present invention, and the automatic displacement of the limit retaining ring is synchronously achieved, so that the plug terminal and the external connecting wire are kept tightly connected during extreme weather, ensuring that the device can not only achieve the active protection of the sensor matrix during extreme weather, but also avoid the problem of the photovoltaic array failure caused by the falling off of the external connecting wire, further improving the stability of the device when used in harsh environments.

[0031] (3) The present invention utilizes the high-speed wind generated by extreme weather, realizes the rotation of the impeller through the flow of air, and realizes the change of the induced current through the change of the wind force, and finally realizes automatic alarm, so that the device can give an automatic early warning during extreme weather, reminding the staff to carry out maintenance and reducing the damage probability of the photovoltaic array under extreme weather.

DETAILED DESCRIPTION OF THE INVENTION

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] As Figures 1 to 7 shown, in the embodiment of the present invention, a photovoltaic control device with a sensor protection function includes a controller body 1. Plug terminals 2 are fixedly installed at equal intervals on the front surface of the controller body 1 near the bottom end. A sensor matrix 3 is fixedly installed at equal intervals on the front surface of the controller body 1 near the top end. An adjustment component 5 is installed on the top end of the front surface of the controller body 1 through a base. A gas collection component 4 is fixedly communicated with the front end of the adjustment component 5. Longitudinal guide rails 6 are fixedly installed on both the left and right sides of the front surface of the controller body 1. A protective cover plate 7 is movably clamped between the two longitudinal guide rails 6. A linkage component 8 is installed at the top end of the protective cover plate 7. The other end of the linkage component 8 is connected to the longitudinal guide rail 6. Limit snap rings 11 are arranged above the plug terminals 2. When the protective cover plate 7 moves up and down relative to the longitudinal guide rail 6 and the adjustment component 5 is in the initial state, the protective cover plate 7 is located below the front surface of the sensor matrix 3.

[0042] In the initial state, the protective cover plate 7 is located below the front surface of the sensor matrix 3. At this time, the external environment can be monitored through the sensor matrix 3. At the same time, an external connecting wire can be inserted into the plug terminal 2, and the distance between the limit snap ring 11 and the plug terminal 2 is the maximum value, completing the control process of the photovoltaic panel in the normal state.

[0043] As Figure 1 and Figure 3 as well as Figure 4 shown, the gas collection component 4 includes a gas collection hood 401. The rear end of the gas collection hood 401 is fixedly communicated with a gas collection tank 402. The rear end of the gas collection tank 402 is communicated with the front end of the adjustment component 5. A main shaft 403 is movably connected inside the gas collection tank 402. An impeller 404 located inside the gas collection tank 402 is fixedly sleeved on the outer side of the main shaft 403. Miniature generators 405 are installed at both the left and right ends of the gas collection tank 402. One end of the main shaft 403 penetrates through one side of the gas collection tank 402 and is connected to the input end of the miniature generator 405.

[0044] When encountering strong convective or strong wind weather, the high-speed external air can enter the interior of the air collection tank 402 after converging through the air collection hood 401, and can drive the impeller 404 to rotate. At this time, the main shaft 403 rotates accordingly and transmits power to the micro generator 405. At this time, the micro generator 405 generates an induced current accordingly. At the same time, the micro generator 405 can be connected to an external alarm. When the induced current generated by the micro generator 405 reaches the set threshold, the external alarm is turned on to complete the automatic warning of extreme weather.

[0045] By utilizing the high-speed wind force generated by extreme weather, the rotation of the impeller 404 is realized through the flow of air, and the change of the induced current is realized through the change of the wind force. Finally, automatic alarm is realized, so that the device can give an automatic warning in extreme weather, reminding the staff to carry out maintenance and reducing the damage probability of the photovoltaic array in extreme weather.

[0046] As Figure 3 and Figure 4 shown, the adjusting assembly 5 includes an adjusting pipe 501. The outer side of the adjusting pipe 501 is connected to the machine base. The front end of the adjusting pipe 501 is communicated with the rear end of the air collection tank 402. A piston plate 502 is movably sleeved inside the adjusting pipe 501. A piston rod 503 is fixedly connected to the rear end of the piston plate 502. The rear end of the piston rod 503 penetrates through the rear end of the adjusting pipe 501 and is connected to the linkage assembly 8. A limiting spring 504 is movably sleeved on the outer side of the piston rod 503. The left and right ends of the limiting spring 504 are respectively connected to one end of the piston plate 502 and one end of the inner cavity of the adjusting pipe 501.

[0047] At the same time, when the high-speed air is exported from the air collection tank 402, the air can enter the interior of the adjusting pipe 501 and exert a thrust on the piston plate 502. At this time, the limiting spring 504 is compressed accordingly, and drives the piston plate 502 and the piston rod 503 to displace backward. When the air pressure is large enough, the limiting spring 504 can be compressed to the limit state. At this time, the piston rod 503 displaces to the rearmost end.

[0048] As Figure 1 and Figure 5 and Figure 6As shown in the figure, the linkage assembly 8 includes heightening frames 801. The number of the heightening frames 801 is two and they are installed on the left and right sides of the top end of the protective cover plate 7. On one side of the top end of each heightening frame 801, a first fixing seat 802 is fixedly installed. One end of the first fixing seat 802 away from the heightening frame 801 is movably connected to a connecting rod 804 through a rotating shaft. One end of the connecting rod 804 away from the first fixing seat 802 is movably connected to a second fixing seat 803 through a rotating shaft. The linkage assembly 8 further includes a linkage frame 805. The left and right ends of the inner side surface of the linkage frame 805 are connected to the second fixing seat 803, and the middle part of the inner side surface of the linkage frame 805 is connected to the piston rod 503. When the limiting spring 504 is in the extreme compression state, the linkage frame 805 moves to the rightmost side and the protective cover plate 7 moves to the front of the sensor matrix 3.

[0049] Embodiment: When the piston rod 503 is displaced to the rearmost end, it can drive the linkage frame 805 to be displaced to the rearmost end at this time. At this time, the connecting rod 804 deflects obliquely upward accordingly, and at the same time exerts a pulling force on the bottom heightening frame 801. Under the guiding action of the longitudinal guide rail 6 and the protective cover plate 7, the protective cover plate 7 is driven to move upward until the protective cover plate 7 moves to the front of the sensor matrix 3. At this time, the protective cover plate 7 can completely block the sensor matrix 3, completing the active protection of the sensor matrix 3 and reducing the damage of the sensor matrix 3.

[0050] By utilizing the high-speed air in extreme weather, taking the high-speed air as power, and using the cooperation between the adjusting assembly 5 and the linkage assembly 8, the active rising of the protective cover plate 7 is realized. The entire rising process is automatically completed, that is, the active protection of the sensor matrix 3 in strong wind weather is realized. The entire protection process can be automatically completed without manual control, which can effectively reduce the damage probability of the sensor matrix 3 in extreme weather and improve the service life.

[0051] As Figure 1 and Figure 7 As shown in the figure, an extension frame 9 is fixedly installed at the bottom end of the linkage frame 805. An installation plate 10 is fixedly installed at the bottom end of the extension frame 9. The top end of the limit retaining ring 11 is connected to the bottom end of the installation plate 10.

[0052] Embodiment: At the same time in extreme weather, since the backward displacement of the linkage frame 805 can synchronously drive the extension frame 9 to move backward. When the extension frame 9 moves backward, it synchronously drives the installation plate 10 and the limit retaining ring 11 to move backward. At this time, the limit retaining ring 11 moves in the direction close to the plug-in terminal 2, so that it pulls the external connecting wire at the bottom to move close to the plug-in terminal 2. This avoids the phenomenon of the external connecting wire falling off due to external force in extreme weather.

[0053] Active protection is achieved by utilizing the automatic rising of the protective cover plate 7 during extreme weather, and the automatic displacement of the limit retaining ring 11 is synchronously realized, so that the plug-in terminal 2 and the external connecting wire are kept tightly connected during extreme weather, ensuring that the device can not only achieve active protection of the sensor matrix 3 during extreme weather, but also avoid the problem of photovoltaic array failure caused by the falling off of the external connecting wire, and further improving the stability of the device when used in harsh environments.

[0054] A protection method for a photovoltaic control device with a sensor protection function includes the following steps:

[0055] S1: When the device is in a normal state, the protective cover plate 7 is located below the front of the sensor matrix 3, and the distance between the limit retaining ring 11 and the plug-in terminal 2 is the maximum value. At this time, the external connecting wire is plugged into the plug-in terminal 2, and the external environment is monitored through the sensor matrix 3;

[0056] S2: When encountering strong convective weather, the wind force increases significantly at this time. The wind force converges through the air collecting hood 401 and enters the interior of the air collecting tank 402, and drives the impeller 404 to rotate. At this time, the main shaft 403 rotates accordingly, and at the same time, the power is transmitted to the micro generator 405. The magnitude of the wind force is judged by the current of the micro generator 405 to complete the early warning;

[0057] S3: At the same time, high-pressure air enters the interior of the regulating pipe 501 and pushes the piston plate 502 to displace backward. At this time, the limit spring 504 can be compressed. When the limit spring 504 is compressed to the limit position, the linkage frame 805 displaces to the rearmost end at this time, and a pulling force is applied to the protective cover plate 7 through the connecting rod 804. At this time, the protective cover plate 7 displaces upward accordingly until it displaces in front of the sensor matrix 3 to block and protect the sensor matrix 3;

[0058] S4: When the linkage frame 805 displaces backward, the extension frame 9 displaces backward accordingly, drives the mounting plate 10 and the limit retaining ring 11 to displace backward, and presses the external connecting wire to keep it tightly connected to the plug-in terminal 2.

[0059] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

When the limit spring (504) is compressed to the limit position, the linkage frame (805) displaces to the rearmost end at this time, and a pulling force is applied to the protective cover plate (7) through the connecting rod (804). At this time, the protective cover plate (7) displaces upward accordingly until it displaces to the front of the sensor matrix (3) to block and protect the sensor matrix (3); S4: When the linkage frame (805) displaces backward, the extension frame (9) displaces backward accordingly, drives the mounting plate (10) and the limit snap ring (11) to displace backward, and presses the external connecting wire to keep its tight connection with the plug-in terminal (2).
