Description

Technical Field

[0001] This invention relates to the field of controller technology, specifically to a light-overlay controller. Background Technology

[0002] Under the major trend of the solar energy industry and the energy structure transitioning towards green and low-carbon development, photovoltaic power generation, as a core application of renewable energy, has been widely penetrated into various fields such as distributed photovoltaic power generation systems, communication base stations, IDC data centers, and outdoor power supply, becoming an important supporting means to alleviate energy shortages and reduce carbon emissions. As the core control device in a photovoltaic system, the tandem photovoltaic (TPV) controller plays a crucial role in photovoltaic module energy harvesting, power regulation, charge and discharge management, and multi-power source coordinated scheduling. Its performance directly determines the power generation efficiency, operational stability, and maintenance costs of the photovoltaic system. It is the core hub connecting photovoltaic modules, energy storage devices, and loads. Through maximum power point tracking (MPPT) technology, it adjusts the operating voltage in real time, ensuring that the photovoltaic modules always operate at their optimal efficiency point, thereby improving overall power generation. It occupies an indispensable position in the efficient utilization of photovoltaic energy. Currently, existing TPV controllers have shortcomings in structural design and adaptability. Some controllers have densely integrated internal electrical components and circuits, making them prone to malfunctions. Furthermore, their complex wiring greatly hinders the pass rate testing in the production process, making it difficult to achieve efficient batch testing of the controller, thus affecting production efficiency and product reliability. Therefore, a new TPV controller is needed to facilitate the normal operation of photovoltaic systems.

[0003] Currently, traditional superimposed light controllers mostly adopt a single cavity layout in their structural design, with all kinds of control components integrated and installed in this single cavity. In harsh and remote outdoor scenarios such as high humidity and strong sandstorms, after long-term service, the equipment is prone to failures such as interface oxidation and corrosion, and internal electronic components becoming damp and failing. This leads to a decrease in equipment stability and inability to operate normally, seriously affecting its reliability in outdoor service. Summary of the Invention

[0004] The purpose of this invention is to provide a superimposed light controller to solve the problem mentioned in the background art that after long-term service in harsh and remote outdoor scenarios such as high humidity and strong sandstorms, the equipment is prone to interface oxidation and corrosion, internal electronic components failure due to moisture, and thus the equipment stability decreases.

[0006] Preferably, the protective cavity and the corresponding inner cavity are arranged alternately side by side, and a vent is provided between the protective cavity and the corresponding inner cavity. An inspection cavity is connected above the wiring bottom cavity. The inspection cavity is located in front of the protective cavity and the inner cavity. The inspection cavity is connected to the protective cavity. A docking through hole is connected to the top of the protective cavity. A connecting hole is connected to the top of the protective cavity. A closing door is rotatably connected to the front of the outer casing.

[0007] Preferably, four support frames are fixedly connected to the top of the outer casing, the control components are fixedly inserted into the corresponding inner cavities, the control components are electrically connected to the external control center, a top connector is fixedly connected above the rotating cavity partition, the top connector is built into the maintenance cavity, a bottom connector is fixedly connected below the rotating cavity partition, the bottom connector is built into the wiring bottom cavity, the bottom connector is electrically connected to the corresponding top connector, and a connecting wire is inserted between the control components and the corresponding bottom connector.

[0008] Preferably, the bottom inspection section includes a bottom frame, which is fixedly connected to the bottom of the outer casing. An activated bottom plate is fixedly inserted inside the bottom frame, and dehumidifying carbon is built into the activated bottom plate. Two hinged flaps are rotatably connected to the bottom of the bottom frame.

[0009] Preferably, the external auxiliary part includes an air extraction assembly, which is fixedly connected to the top of the four support frames. The air extraction assembly is electrically connected to an external control center. Multiple torsion joints are rotatably connected to the air extraction port of the air extraction assembly. The torsion joints are rotatably connected to the corresponding mating through holes. The outer wall of the end of the torsion joint is threaded. An external connector is provided on the top of the air extraction assembly. Two fixed side blocks are fixedly connected to the outer wall of the air extraction assembly. The two fixed side blocks are fixedly connected to the top of the outer casing.

[0010] Preferably, the external control unit includes a telescopic cylinder, which is fixedly connected to the top of the inspection chamber and electrically connected to an external control center. The telescopic shaft of the telescopic cylinder is fixedly connected to a drive top plate, and two traction rods are rotatably connected to the drive top plate. Both traction rods are movably connected to corresponding communicating holes, and threaded rods are fixedly connected to the ends of both traction rods.

[0011] Preferably, the inner insert housing is fixedly inserted into the corresponding protective cavity. The inner insert housing has a mating air hole and a locking slot on its inner wall. The top of the inner insert housing has a mating screw hole, and the mating screw hole is internally threaded to a corresponding torsion joint. The lifting frame has a misaligned through hole and a connecting groove on its top, which is threaded to the bottom of the traction rod.

[0012] Preferably, the docking plate is fixedly inserted into the interior of the inner insert housing. The interior of the docking plate has two telescopic grooves. The interior of each of the two telescopic grooves is slidably connected to an inner moving bracket. Each of the two inner moving brackets is fixedly connected to a rod.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows: Through a multi-cavity partitioned structure design, the interior of the outer casing of the outer part is divided into a wiring bottom cavity, an inner insertion cavity, a protective cavity, and a maintenance cavity. Each cavity has a clear functional area and works in coordination, overcoming the layout defects of traditional controllers with a single cavity. Specifically, the control components are installed in the inner insertion cavity, the dehumidification unit is installed in the protective cavity, and the wiring connection structure is placed in the wiring bottom cavity, achieving physical separation of the control elements, wiring, and dehumidification components. This reduces mutual interference and lowers the probability of external dust and moisture directly contacting the core components. Simultaneously, the partition plate of the rotating cavity provides secondary protection for the control components, and the active bottom plate of the bottom inspection section and the dehumidification cotton board of the dehumidification section are protected from external contamination. The auxiliary air extraction components work together to form a full-cavity dehumidification system: the air extraction components, through the cooperation of the torsion joint and the inner shell, realize the airflow circulation inside the protective cavity. The dehumidifying cotton plate absorbs the moisture in the circulating airflow, and the active base plate absorbs the residual moisture in the wiring bottom cavity, effectively reducing the humidity inside the cavity. The external control unit drives the dehumidification unit to slide up and down, ensuring that the dehumidification range covers the entire protective cavity, further improving the uniformity of dehumidification. The synergistic effect of the above structures can effectively avoid the problems of interface oxidation and corrosion, internal electronic component failure due to moisture, and other faults that are prone to occur after long-term service in harsh and remote outdoor scenarios such as high humidity and strong sandstorms in the solar energy industry, which would lead to a decrease in equipment stability.

[0027] Working principle: After assembly, the external control center sends control signals to the control component 301, the air extraction component 501, and the telescopic cylinder 601. The control component 301 transmits signals and power through the top terminal 303, the bottom terminal 304, and the connecting line 305. In the solar energy industry, through integrated maximum power point tracking technology, the output voltage and current data of the photovoltaic module are collected in real time, and the operating parameters of the control component 301 are dynamically adjusted to precisely regulate the operating voltage, so that the photovoltaic module always operates at the optimal efficiency point. This effectively avoids the impact of external light and temperature changes on the photovoltaic output efficiency, thereby significantly improving the overall power generation of the entire photovoltaic system.

[0028] During dehumidification, the external control center controls the telescopic cylinder 601 to extend and retract, causing the top plate 602 and the traction rod 603 to move up and down. This, in turn, causes the lifting frame 703 and the dehumidification unit 8 to slide along the inner insert housing 701, thereby connecting the vent between the protective cavity 104 and the inner insert cavity 103, the mating vent on the inner insert housing 701, and the misaligned through hole on the lifting frame 703. Then, the air extraction component 501 is activated, extracting humid air from inside the protective cavity 104 through the torsion joint 502 and the mating vent on the inner insert housing 701. At the same time, dry air can be introduced through the external joint 503, forming an airflow circulation. The dehumidifying cotton plate 805 inside the protective cavity 104 adsorbs moisture in the circulating airflow, and the active bottom plate 402 of the bottom inspection unit 4 adsorbs moisture in the wiring bottom cavity 102. The three work together to achieve full cavity dehumidification, avoiding interface oxidation and component moisture.

[0029] During maintenance, operators can open the closed door 108 on the front of the outer casing 101 and inspect and maintain the wiring of the top connector 303 and control component 301 through the maintenance chamber 105; open the closed flip cover 403 of the bottom connector 401 to replace the active bottom plate 402; move the outer lever 804 to remove the docking plate 801 and replace the dehumidifying cotton plate 805. The entire maintenance process can be carried out with targeted monitoring as needed to avoid affecting the internal structure of other chambers.
