Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic module performance testing equipment, and more specifically, to a photovoltaic module testing equipment that is easy to install. Background Technology

[0002] As the core component of a solar power generation system, the performance testing of photovoltaic (PV) modules is crucial for ensuring the system's efficient operation. Currently, most PV module testing equipment on the market adopts a handheld or fixed structure, requiring manual operation or simple supports for positioning. For example, some testing equipment requires additional clamps or bolts to be fixed to the PV module frame, resulting in a cumbersome and time-consuming installation process, and making it difficult to guarantee positioning accuracy.

[0003] With the expansion of photovoltaic power plants, testing efficiency and convenience have become key concerns in the industry. In existing technologies, the installation and positioning of testing equipment typically rely on manual experience, which not only increases operational difficulty but may also lead to component damage or safety hazards. Especially in large-scale photovoltaic arrays, repeated installation and adjustment of equipment significantly reduces testing efficiency, failing to meet the demands of rapid inspection. Therefore, there is an urgent need for testing equipment that can simplify the installation process, improve positioning accuracy, and adapt to different photovoltaic module structures to overcome the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic module testing device that is easy to install, in order to solve the problems of cumbersome installation, low positioning accuracy and low testing efficiency of existing photovoltaic module testing devices.

[0005] This utility model is achieved through the following technical solution:

[0006] A photovoltaic module testing device that is easy to install includes: a main unit, a horizontal positioning mechanism, a vertical positioning mechanism, and a testing cable. The vertical positioning mechanism and the horizontal positioning mechanism are mounted on the photovoltaic module mounting frame. The vertical positioning mechanism is detachably connected to the back of the main unit, and the horizontal positioning mechanism is detachably connected to the side of the main unit. The two ends of the testing cable are detachably connected to the terminals of the main unit and the photovoltaic module, respectively.

[0007] Optionally, the vertical positioning mechanism includes a fixed base and a first positioning component. The fixed base is disposed on the mounting frame of the photovoltaic module, the first positioning component is detachably connected to the fixed base, and the back of the main unit is detachably connected to the first positioning component.

[0008] Optionally, the horizontal positioning mechanism includes a second positioning component, a limiting component, a sliding component, and a locking component. The second positioning component is mounted on the mounting frame of the photovoltaic module. The limiting component is connected to the second positioning component. The limiting component is provided with a sliding hole. The sliding component passes through the sliding hole. The locking component is connected to one end of the sliding component. The locking component is detachably connected to the side of the host.

[0009] Optionally, the locking assembly includes a rotating part and a pin part. A connection hole is provided on the side of the main unit, and a snap-fit ​​part is provided inside the connection hole. The rotating part passes through the connection hole, and the pin part is located at the front end of the rotating part. The pin part is adapted to the snap-fit ​​part.

[0010] Optionally, the host is provided with a detection interface, and one end of the detection cable is detachably connected to the detection interface.

[0015] Optionally, the surface of the host is provided with heat dissipation vents.

[0016] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0017] By setting up independent horizontal and vertical positioning mechanisms and using detachable connections with the back and sides of the main unit, the complex fixing process that relies on additional clamps and bolts in the traditional method is eliminated, enabling the equipment to quickly complete the installation and positioning on the photovoltaic module frame. It is especially suitable for the inspection of large-scale photovoltaic arrays, reducing the time required for single-point inspection and improving the overall inspection efficiency.

[0018] The horizontal and vertical positioning mechanisms provide a stable and accurate benchmark for the equipment, effectively avoiding positioning deviations caused by reliance on personal experience in traditional manual operations. The standardized positioning method ensures that the position of the test connector relative to the photovoltaic module remains consistent, thereby guaranteeing the comparability and accuracy of test data between different modules and improving the overall reliability of the test results.

[0019] By eliminating cumbersome additional fasteners, the structure is more compact and lightweight, which not only reduces the technical requirements for operators and simplifies the operation steps, but also reduces the risk of damage to the surface or frame of photovoltaic modules due to improper use of tools or operational errors during installation and adjustment, thus improving the safety of the operation process.

Detailed Implementation

[0024] The following is a detailed description of the embodiments, in conjunction with the accompanying drawings.

[0025] Reference Figure 1 A photovoltaic module testing device that is easy to install includes: a main unit 1, a horizontal positioning mechanism, a vertical positioning mechanism, and a testing cable 7. The vertical and horizontal positioning mechanisms are mounted on the mounting frame of the photovoltaic module 9. The vertical positioning mechanism is detachably connected to the back of the main unit 1, and the horizontal positioning mechanism is detachably connected to the side of the main unit 1. Both ends of the testing cable 7 are detachably connected to the terminals of the main unit 1 and the photovoltaic module 9, respectively. The main unit 1 integrates a control circuit, a power supply, a data processor, and a communication module. The back and side of the main unit 1 are provided with connection interfaces (such as quick-connect interfaces, slots, or threaded holes) for quick assembly and disassembly with the vertical and horizontal positioning mechanisms. The horizontal positioning mechanism fixes and positions the main unit 1 horizontally, and the vertical positioning mechanism fixes and positions the main unit 1 vertically. The testing cable 7 electrically connects the main unit 1 to the terminals of the photovoltaic module 9, and transmits the collected relevant signals to the main unit 1 through the testing cable 7.

[0026] In some embodiments, the vertical positioning mechanism includes a fixed base and a first positioning component 2. The fixed base is disposed on the mounting frame of the photovoltaic module 9, and the first positioning component 2 is detachably connected to the fixed base. The back of the main unit 1 is detachably connected to the first positioning component 2. One end of the first positioning component 2 has an interface (such as a quick-connect female, clip, or bolt) that matches the fixed base; the other end of the first positioning component 2 has a connector that matches the connection interface on the back of the main unit 1. The fixed base can be disposed on the aluminum alloy mounting frame of the photovoltaic module 9 using various quick-clamping methods, for example:

[0027] Preferred Method 1: Use a "C-shaped" or "U-shaped" buckle structure, with rubber or engineering plastic anti-slip pads on the inside; during installation, simply align the opening of the buckle with the edge of the frame and snap it in firmly, relying on the elasticity and friction of the material to achieve quick and damage-free fixing.

[0028] Preferred Method Two: Use a magnetic base. If the photovoltaic module frame is made of magnetic material (such as certain special steels), a magnetic sheet can be pre-attached to the frame, and the fixing base can be magnetically attached to the frame, achieving one-second installation and removal.

[0029] Preferred Option 3: Employ an adaptive width fixture. The width of the fixture opening can be adjusted using a knob or lever to accommodate component frames of varying thicknesses, achieving versatility.

[0030] In some embodiments, the horizontal positioning mechanism includes a second positioning component 3, a limiting component 4, a sliding component 5, and a locking component 6. The second positioning component 3 is mounted on the mounting frame of the photovoltaic module 9. The limiting component 4 is connected to the second positioning component 3 and has a sliding hole through which the sliding component 5 passes. The locking component 6 is connected to one end of the sliding component 5 and is detachably connected to the side of the main unit 1. The second positioning component 3 is fixed to the mounting frame (typically an aluminum alloy frame) of the photovoltaic module 9 by a quick-clamping method. For example:

[0031] It can adopt a "C-shaped" or "U-shaped" buckle structure, with rubber or engineering plastic anti-slip pads on the inside, and use the elasticity and friction of the material to clamp the frame edge to achieve non-destructive fixation;

[0032] A magnetic base can be used; if the frame is made of magnetic material (or a magnetic conductive sheet is pre-attached), it can be fixed by magnetic attraction.

[0033] An adaptive width fixture can be used, with the opening width adjusted by a knob or lever to accommodate frames of different thicknesses.

[0034] The limiting component 4 is connected to the second positioning component 3 via a quick-connect interface, snap-fit, or bolt to ensure stability. The limiting component 4 has a sliding hole (such as a linear bearing or smooth through-hole) to guide the movement of the sliding component 5. The sliding component 5 can be a metal rod (such as stainless steel or aluminum alloy) or a high-strength plastic guide rail, passing through the sliding hole of the limiting component 4. The surface of the sliding component 5 may be coated with a lubricating coating or use a low-friction material to ensure smooth movement. The locking component 6 is fixed to one (or both) end of the sliding component 5 and includes a locking mechanism (such as a knob, lever, or eccentric snap). When the main unit 1 moves to the target position, rotating the knob of the locking component clamps the sliding component 5, preventing further sliding. The locking component 6 is detachably connected to the side of the main unit 1 via a quick-connect interface, slot, or threaded hole. For example, the side of the main unit 1 has a standardized slot, and the connector on the locking component 6 can be quickly inserted and self-locking for a secure connection.

[0035] In some embodiments, refer to Figure 3 The locking component 6 includes a rotating part 601 and a pin part 602. A connecting hole is provided on the side of the main unit 1, and a snap-fit ​​part 102 is provided inside the connecting hole. The rotating part 601 passes through the connecting hole, and the pin part 602 is located at the front end of the rotating part 601. The pin part 602 is adapted to the snap-fit ​​part 102. During installation, the back of the main unit 1 is connected to the vertical positioning mechanism, and the connecting hole on the side of the main unit 1 is aligned with the locking component 6 on the sliding component 5. The sliding component 5 is pushed so that the rotating part 601 passes through the connecting hole on the side of the main unit 1. At this time, the pin part 602 has not yet engaged with the snap-fit ​​part 102. The rotating part 601 is rotated (for example, 90° or 180° clockwise) to drive the pin part 602 to form a snap-fit ​​or threaded engagement with the snap-fit ​​part 102. For example, if the locking part 102 is an L-shaped slot, the pin part 602 can slide into and lock along the slot; if the locking part 102 is provided with internal threads, the pin part 602 can be tightened by rotation; during disassembly, the reverse operation of installation is performed to separate the main unit 1 from the locking component 6. The main unit 1 can be fixed or released by a simple rotation operation, which greatly reduces the installation time (for example, from several minutes of traditional bolt fixing to a few seconds), and meets the rapid inspection needs of large-scale photovoltaic arrays.

[0036] In some embodiments, the host 1 is provided with a detection interface 101, one end of the detection cable 7 is detachably connected to the detection interface 101, and the other end of the detection cable 7 is detachably connected to the terminal of the photovoltaic module 9. The detection interface 101 is integrated into the housing of the host 1 and adopts a standardized quick-connect interface, such as a waterproof USB-C, RJ45, or a dedicated quick-connect interface (such as an M12 connector). The interface contains data communication pins and power pins to simultaneously transmit detection data and supply power to the terminal of the photovoltaic module 9. A rubber sealing ring is provided around the interface or an IP67-level protection design is adopted to ensure dustproof and waterproof performance when used outdoors. One end of the detection cable 7 is equipped with a connector (such as a USB-C male or M12 male) that matches the detection interface 101. The connector integrates a locking mechanism (such as a spring clip or a twist-lock structure). When connecting, simply align the connector with the detection interface 101 and insert it. A "click" sound indicates that it is locked in place, achieving quick insertion and removal in one second. When disassembling, pressing the release button on the connector or rotating the unlocking ring can easily separate it. The other end of the test cable 7 is also detachable, matching the interface on the terminal of the photovoltaic module 9. The interface of the photovoltaic module 9 terminal can be magnetic (like a MagSafe-like structure) or quick-connect, with a permanent magnet or electromagnetic lock embedded around the interface to ensure that the test cable 7 will not accidentally detach when connected to the photovoltaic module 9 terminal. For example, when the test cable 7 is connected to the photovoltaic module 9 terminal via magnetic attraction, the test cable 7 automatically aligns and locks with the photovoltaic module 9 terminal using magnetic force. The test cable 7 can be a shielded twisted pair or coaxial test cable to reduce signal interference. The length can be customized as needed, and a test cable management strap is provided for easy storage. Furthermore, the test interface 101 and the test cable connector are color-coded or marked to prevent mis-insertion.

[0037] In some embodiments, there are multiple detection interfaces 101, which are arrayed on the host 1. By setting multiple arrayed detection interfaces, the host can simultaneously connect to the terminals of multiple photovoltaic modules 9, enabling synchronous detection of multiple photovoltaic modules or different parts of the same module. This significantly reduces the time required for frequent relocation or repeated installation of traditional equipment, and is especially suitable for rapid inspection of large-scale photovoltaic power plants, improving detection efficiency by several times.

[0038] In some embodiments, an operation panel is provided on the front of the main unit 1, and the operation panel is provided with several operation buttons. The operation panel is electrically connected to the detection and control module inside the main unit 1. The operation panel is electrically connected to the detection and control module (i.e., the main control circuit board) inside the main unit 1 via a flexible printed circuit board (FPC) or wire. Integrating the control functions on the front of the main unit 1 allows operators to immediately start detection, switch modes, or terminate tasks on-site after the equipment is installed.

[0039] In some embodiments, a display screen is provided on the front of the host 1, and the display screen is electrically connected to the detection and control module inside the host 1. The display screen can be a high-brightness, wide-viewing-angle LCD screen or an OLED screen. The display screen can display the operating status of the device in real time, such as power level, communication connection status (such as 4G / 5G / Wi-Fi signal strength), and the currently running detection mode (such as infrared thermal imaging, EL detection, IV curve testing).

[0040] In some embodiments, the surface of the host unit 1 is provided with heat dissipation vents 103. The heat dissipation vents 103 can be a dense mesh or a louvered grille. The sloping grille ensures smooth airflow while effectively preventing the direct intrusion of rainwater, dust, and larger foreign objects, meeting IP54 or higher dust and water resistance standards. Inside the host unit 1, guide vanes or air ducts can be installed at positions corresponding to the heat dissipation vents 103 to directly guide airflow to the main heat-generating components, such as the power module and data processor (CPU / FPGA), achieving precise heat dissipation. When photovoltaic testing equipment operates outdoors, its internal electronic components (especially power components and processors) generate a large amount of heat and also absorb solar radiation heat. An efficient heat dissipation system effectively prevents processor throttling, accelerated component aging, and even equipment shutdown caused by overheating, ensuring the accuracy of the test data and the reliability of the equipment.
