[0002] A solar array simulator is a high-tech device specifically designed to simulate the electrical characteristics of solar photovoltaic arrays under different environmental conditions. It belongs to the category of photovoltaic simulation devices. Through the simulator body, it simulates the solar radiation spectrum, adjusts the light intensity, and simulates the current and voltage characteristics to simulate the behavior of photovoltaic power generation systems under different lighting conditions. This simulator plays an important role in the research and development of photovoltaic systems, component testing and certification, inverter testing, and education and training.

[0003] The solar array simulator includes a mounting plate, a simulator body, and a shell. The simulator body is detachably connected to the shell by bolts, and the mounting plate is installed on one side of the shell by bolts. To ensure the accurate operation of the solar array simulator, periodic maintenance is required. However, during maintenance, the mounting plate needs to be removed, which requires removing the bolts on the mounting plate one by one. The disassembly process is cumbersome, and repeated disassembly can easily cause stripping between the threaded holes and bolts, making the installation of the mounting plate unstable.

[0004] Therefore, it is necessary to provide a new photovoltaic simulation device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a photovoltaic simulation device.

[0006] The photovoltaic simulation device provided by this utility model includes: a shell, a mounting plate detachably connected to one side of the shell, a fixed frame nested outside the mounting plate, a driving component movably connected to the side wall of the fixed frame, the driving component being inserted into the shell, the driving component passing through the mounting plate and attaching the mounting plate to the side wall of the shell, and an elastic component detachably connected inside the shell to limit the movement of the driving component.

[0007] Preferably, the outer shell has detachable fixing blocks installed on both sides of the inner cavity sidewalls, the elastic element is fixedly installed in the fixing block, the other end of the elastic element passes through the sidewall of the outer shell, the back of the outer shell is movably connected to a fixing frame, and a plurality of driving elements are inserted through the sidewall of the fixing frame, with one end of the driving element passing through the elastic element.

[0008] Preferably, a simulator body is detachably connected inside the outer shell. Multiple interfaces are installed on the back of the simulator body. All interfaces pass through the mounting plate. Multiple sliding grooves are provided on the top wall of the fixed frame. Limiting components corresponding to the multiple interfaces are movably connected in the sliding grooves.

[0009] Preferably, the limiting component includes a slider and two clamping plates disposed opposite to each other on both sides of the inner cavity of the slider. A protective shell is fixedly connected to the bottom end of each clamping plate. The side walls of the two protective shells are in contact with each other. A semi-circular arc groove is opened on the side wall of each protective shell. A reset spring is fixedly connected to the top of each clamping plate.

[0010] Preferably, the elastic element includes a return spring, one end of which is fixedly connected to the inner cavity side wall of the fixing block, and the other end of which is fixedly connected to a button. The button passes through the outer shell side wall, and the button side wall has a sliding groove, and the sliding groove side wall is fixedly connected to a plug rod for limiting the drive element.

[0011] Preferably, the driving component includes a threaded sleeve, one end of which passes through a button, and the other end of which is integrally connected to a limiting plate. The side wall of the limiting plate is fitted with the side wall of the mounting plate.

[0013] Compared with related technologies, the photovoltaic simulation device provided by this utility model has the following beneficial effects:

[0014] 1. This utility model provides a photovoltaic simulation device. In specific implementation, the driving component and the elastic component cooperate, and the elastic component is inserted into the driving component to fix the driving component. The driving component also limits the mounting plate, thereby realizing the installation of the mounting plate. When the mounting plate needs to be disassembled, simply press the elastic component. At this time, the elastic component loses its limit on the driving component, so the fixing frame and the mounting plate can be removed, which facilitates the maintenance and replacement of the internal parts of the device.

[0015] 2. Slide the limiting component within the slide groove to adjust the distance between the protective shell and the interface. When the protective shell is close to the interface, it can protect the interface from dust. When the protective shell is far from the interface, it can help manage the data cable.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 — Figure 6 ,in, Figure 1 A schematic diagram of the overall structure of the photovoltaic simulation device provided by this utility model; Figure 2 A partial structural schematic diagram of the photovoltaic simulation device provided by this utility model; Figure 3 A side cross-sectional view of the photovoltaic simulation device provided by this utility model; Figure 4 A schematic diagram of the elastic component structure of the photovoltaic simulation device provided by this utility model; Figure 5 A schematic diagram of the limiting component structure of the photovoltaic simulation device provided by this utility model; Figure 6 for Figure 2 The enlarged schematic diagram at point a is shown.

[0025] In practical implementation, a photovoltaic simulation device has the following structure: Figure 1 — Figure 6As shown, it includes: a shell 1, a mounting plate 4 detachably connected to the back side wall of the shell 1, a fixing frame 5 nested outside the mounting plate 4, the fixing frame 5 nested in the back of the shell 1, threaded sleeves 601 with threaded grooves on the inner cavity side wall of the fixing frame 5 are inserted on both sides of the side wall of the fixing frame 5, a limiting plate 602 is integrally connected to the tail end of the threaded sleeve 601, the limiting plate 602 is in contact with the side wall of the mounting plate 4, fixing blocks 2 are bolted to the inner cavity side walls of the shell 1 on both sides, an elastic element 3 is welded inside the fixing block 2, the elastic element 3 includes a return spring 301, one end of the return spring 301 is welded to the inner cavity side wall of the fixing block 2, and a button 302 is welded to the other end of the return spring 301, the other end of the button 302 passes through the side wall of the shell 1, a sliding groove 303 is provided on the side wall of the button 302, and a plug rod 304 for limiting the threaded sleeve 601 is integrally connected to the side wall of the sliding groove 303;

[0026] It should be noted that when fixing the mounting plate 4, first pass the threaded sleeve 601 through the mounting plate 4, then press the button 302 and insert the threaded sleeve 601 into the button 302. After that, release the button 302. Under the action of the return spring 301, the button 302 is subjected to a force that extends out of the side wall of the outer shell 1, thereby inserting the plug rod 304 into the threaded sleeve 601. At this time, the limiting plate 602 is just in contact with the side wall of the mounting plate 4, thereby fixing the threaded sleeve 601.

[0027] like Figure 2 and Figure 6 As shown, the simulator body is bolted inside the outer shell 1. Multiple interfaces 7 are installed on the back of the simulator body. All interfaces 7 pass through the mounting plate 4. Multiple sliding grooves 8 are opened on the top wall of the fixed frame 5. Each of the multiple sliding grooves 8 is rotatably connected to a limiting component 9 corresponding to each of the multiple interfaces 7.

[0028] like Figure 5 and Figure 6 As shown, the limiting component 9 includes a slider 901 and two opposing clamping plates 902. Both clamping plates 902 are inserted into the slider 901. The bottom ends of both clamping plates 902 are fixedly connected to protective shells 904. The side walls of the two protective shells 904 are in contact with each other. The side walls of the two protective shells 904 are provided with semi-circular arc grooves. The two semi-circular arc grooves form a circular hole. The two clamping plates 902 are fixedly connected to a second return spring 905 near the top end.

[0029] It should be noted that two rotating rods 903 are rotatably connected to the inner wall of the slider 901. The two rotating rods 903 pass through the two clamping plates 902 respectively. When the tops of the two clamping plates 902 are pressed, the protective shells 904 at the bottom of the two clamping plates 902 will rotate away from each other, so that the data cable can be inserted into the semi-circular groove in the protective shell 904. Then, when the two clamping plates 902 are released, under the reset action of the reset spring 905, the protective shells 904 at the bottom of the two clamping plates 902 will stick together, thereby protecting and managing the data cable.

[0030] like Figure 3 As shown, the driving component 6 includes a threaded sleeve 601. One end of the threaded sleeve 601 passes through the button 302, and the other end of the threaded sleeve 601 is integrally connected to a limiting plate 602. The side wall of the limiting plate is in contact with the side wall of the mounting plate 4. A threaded rod 603 is movably connected inside the threaded sleeve 601. A limiting plate 604 is nested outside the threaded rod 603. The side wall of the limiting plate 604 is in contact with the side wall of the fixing frame 5 adjacent to the mounting plate 4. One end of the threaded rod 603 passes through the side wall of the fixing frame 5 and is fixedly connected to a knob 605.

[0031] It should be noted that when one end of the threaded sleeve 601 passes through the button 302, the button 302 restricts the threaded sleeve 601 horizontally, preventing the threaded sleeve 601 from moving and rotating freely. At this time, the limiting plate 602 is in contact with the side wall of the mounting plate 4, thereby fixing the mounting plate 4. When the knob 605 is turned, the knob 605 drives the threaded screw 603 to rotate. Since the threaded sleeve 601 cannot rotate, the limiting plate 604 applies a sliding force to the fixing frame 5 away from the mounting plate 4 under the drive of the threaded screw 603, thereby adjusting the position of the fixing frame 5, which facilitates the adjustment of the position of the slider 901 in the slide groove 8.

[0032] like Figure 6 As shown, the slide groove 8 has multiple sawtooth-shaped grooves on both sides of its sidewalls. The slider 901 has multiple sawtooths that match the grooves integrally connected to the outer sidewalls on both sides of its sidewalls. The multiple sawtooths mesh with the sidewalls of the grooves.

[0033] It should be noted that pulling the slider 901 upwards causes the serrations to disengage from the groove. At this time, the slider 901 can be positioned according to the function of the protective shell 904 required by the user. If the protective shell 904 is required to protect the interface 7 from dust, the slider 901 can be slid to the end adjacent to the interface 7. At this time, the protective shell 904 is in contact with the side wall of the mounting plate 4, thereby protecting the interface 7 from dust. If the data cable needs to be organized, the slider 901 can be slid to the end away from the interface 7. At this time, the protective shell 904 is away from the interface 7, allowing the protective shell 904 to organize the data cable.

[0034] The working principle provided by this utility model is as follows: Press button 302, then pass threaded sleeve 601 through button 302, and then release button 302. Under the elastic force of return spring 301, the plug rod 304 inside button 302 will be inserted into threaded sleeve 601, thereby positioning threaded sleeve 601. At this time, the tail end of threaded sleeve 601 is just attached to mounting plate 4 and the mounting plate 4 is installed on the back of outer shell 1, realizing the fixed installation of mounting plate 4. When it is necessary to repair or replace the simulator body, simply press button 302 to remove the protective plate and fixing frame 5, which is simple and quick.

[0035] By adjusting the position of slider 901 within the slide groove 8, the distance between protective shell 904 and mounting plate 4 can be adjusted, thus enabling protective shell 904 to perform different functions. When protective shell 904 is close to mounting plate 4, it acts as a dustproof barrier for interface 7, preventing dust from entering interface 7 and causing poor contact. When protective shell 904 is far from mounting plate 4, it acts as a cable management barrier for data cables, preventing data cables from tangling and causing safety hazards and inconvenience in disassembly and installation.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
