[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] This invention provides a solar photovoltaic cell simulator, such as... Figures 1 to 7 As shown, the simulator includes a main body 1, a control area 2 on the front side of the main body 1, a first connecting end 3 on the rear side of the main body 1, a second connecting end 4 on one side of the first connecting end 3, protective covers 5 on the outer sides of both the first connecting end 3 and the second connecting end 4, a protective door 6 rotatably connected to one side of the protective cover 5, connecting lines 7 at the bottom of both the first connecting end 3 and the second connecting end 4, a first mounting plate 8 fixedly installed on the inner wall of the bottom of the protective cover 5 of the first connecting end 3, a second mounting plate 9 fixedly installed on the bottom of the protective cover 5 of the second connecting end 4, a moving groove on one side of both the first mounting plate 8 and the second mounting plate 9, mounting grooves on both sides of the moving grooves and inside the first mounting plate 8 and the second mounting plate 9, a fixing structure 10 inside the mounting grooves, and a storage device fixedly installed on the top of the protective cover 5. Storage box 11, with a conveying pipe 12 fixedly installed at the bottom of storage box 11, and a control valve fixedly installed at one end of conveying pipe 12. An alarm 13 is installed on one side of storage box 11, and the alarm 13 is fixedly installed on the inner wall of the top of protective cover 5. Heat dissipation holes are provided on both sides of protective cover 5. Two sealing baffles 14 are provided on the inner walls of both sides of protective cover 5. An electromagnetic block 15 is fixedly installed on one side of the two sealing baffles 14 that is close to each other. The electromagnetic block 15 is electrically connected to control area 2. The bottom of the two sealing baffles 14 is slidably connected to the top of the first mounting plate 8 and the second mounting plate 9. A fixing plate 16 is provided between the two sealing baffles 14. A connecting spring 17 is fixedly installed on both sides of fixing plate 16. A groove is provided on the side of the two sealing baffles 14 near the connecting spring 17. One end of the connecting spring 17 is fixedly installed in the groove.

[0028] Open the protective cover 5 by rotating the protective door 6, pass the connecting wire 7 through the movable grooves on the first mounting plate 8 and the second mounting plate 9, and then connect the connecting wire 7 to the first connecting end 3 and the second connecting end 4 respectively. At the same time, the movable grooves restrict the end of the connecting wire 7 to prevent collisions or damage to the connection points between the connecting wire 7 and the first connecting end 3 and the second connecting end 4, thus affecting the stability of the connection. After installation, rotate the protective door 6 to close the protective cover 5, thereby further improving the protection of the connecting wire 7 and the first connecting end 3 and the second connecting end 4. When a fire occurs at the connection point, smoke will be generated. In foggy conditions, the smoke alarm 13 sounds an alarm, cutting off the simulator power. The electromagnetic blocks 15 lose their magnetism and no longer repel each other. The elastic action of the connecting spring 17 causes the two sealing baffles 14 to move closer to each other. When one side of the sealing baffle 14 is in contact with the side of the fixed plate 16, it blocks the heat dissipation holes, keeping the inside of the protective cover 5 sealed. At the same time, the carbon dioxide gas inside the storage box 11 is delivered to the inside of the protective cover 5 through the delivery pipe 12 to extinguish the fire at the connection point. This facilitates the rapid isolation of the connection point from the fire source, effectively preventing the spread of fire and making it easy to use.

[0029] like Figures 1 to 2 As shown, the simulator body 1 has first heat dissipation vents on both sides, and two second heat dissipation vents are opened on the rear side of the simulator body 1 and at the bottom of the protective cover 5. The connecting line 7 extends through the moving groove to the bottom of the first mounting plate 8 and the second mounting plate 9. The fixing structure 10 is located on both sides of the connecting line 7, and it is distributed in a linear array with the center of the first mounting plate 8 and the second mounting plate 9.

[0030] The first and second heat dissipation vents dissipate heat from the inside of the simulator body 1, improving the performance of the simulator body 1. The fixing structure 10 facilitates the limitation of the connecting cable 7, improving the stability of the connecting cable 7 on the first mounting plate 8 and the second mounting plate 9. This reduces the risk of poor contact caused by loose connection of the connecting cable 7, which would affect the connection between the connecting cable 7 and the simulator and thus affect its use.

[0031] like Figures 5 to 7 As shown, carbon dioxide gas is installed inside the storage box 11. The storage box 11 and the delivery pipe 12 are both located at the top of the first connecting end 3 and the second connecting end 4. The two sealing baffles 14, the fixing plate 16, the electromagnetic block 15 and the connecting spring 17 are all symmetrically arranged around the center of the protective cover 5. The two sealing baffles 14 and the electromagnetic block 15 are located on both sides of the heat dissipation hole. One side of the fixing plate 16 is fixedly installed to the inner wall of the protective cover 5. The groove and the connecting spring 17 are located on the upper and lower sides of the electromagnetic block 15. The connecting spring 17 is in a stretched state.

[0032] Carbon dioxide gas from the storage tank 11 is delivered to the interior of the protective cover 5 via the delivery pipe 12 to extinguish the fire at the connection point. The symmetrically arranged sealing baffle 14, fixing plate 16, electromagnetic block 15, and connecting spring 17 ensure that the heat dissipation holes on both sides of the protective cover 5 are blocked. When the simulator body 1 is powered off, the electromagnetic block 15 loses its magnetism, and under the contraction of the connecting spring 17, the bottom of the sealing baffle 14 moves closer to the top of the first mounting plate 8 and the second mounting plate 9, blocking the heat dissipation holes and keeping the protective cover 5 sealed, which facilitates fire extinguishing at the connection point and reduces the spread of the fire.

[0033] like Figures 5 to 6 As shown, the protective door 6 has a movable groove at one end near the first mounting plate 8 and the second mounting plate 9. A stop block 18 is movably connected inside the movable groove. One end of the stop block 18 is located inside the movable groove. A connecting rod 19 is fixedly installed on the side of the stop block 18 away from the movable groove. The connecting rod 19 is located inside the movable groove, and one end of it is fixedly installed to the inner wall of the movable groove.

[0034] The movable groove on one side of the protective door 6 facilitates the installation of the connecting rod 19 and the stop block 18. When the protective door 6 closes the protective cover 5, one side of the stop block 18 moves to the side of the fixed structure 10 to block the movable groove, further improving the sealing of the protective cover 5, facilitating the release of carbon dioxide inside the storage box 11, and improving the fire extinguishing effect.

[0035] like Figures 8 to 10 As shown, the fixed structure 10 includes a movable block 100. Movable plates 101 are provided on both sides of the movable block 100. A movable block 102 is fixedly installed on one side of the movable plate 101. A movable rod 103 is fixedly installed on the side of the movable block 100 away from the movable plate 101. A pressing block 104 is fixedly installed on one side of the movable rod 103. Pushing blocks 105 are provided on both sides of the pressing block 104. A first compression spring is fixedly installed between the pushing blocks 105. A first rack 106 is fixedly installed on one side of the pushing block 105. A gear 107 meshes with the bottom of the first rack 106. A rotating rod is fixedly installed in the middle of the gear 107. A second rack 108 meshes with one side of the gear 107. A telescopic rod 109 is fixedly installed at the bottom of one end of the second rack 108. A placement groove is opened on the side of the movable block 102 near the telescopic rod 109. The telescopic rod 109 is located inside the placement groove, and one end of it is fixedly installed to the inner wall of the placement groove.

[0036] When the connecting line 7 moves inside the moving groove, it pushes the connecting line 7 to move the movable block 100. The movable block 100 then moves the moving rod 103 and the pressing block 104, causing the pressing block 104 to press the pushing block 105 away from each other and stretching the first compression spring. When the pushing block 105 moves, it drives the first rack 106 to move, causing the gear 107 to drive the rotating rod to rotate. This causes the second rack 108 to move the moving block 102 towards the connecting line 7. The moving block 102 then moves the moving plate 101 into the moving groove and fits against the outside of the connecting line 7, thus limiting the connecting line 7 and fixing it to the first mounting plate 8 and the second mounting plate 9. This connects the connecting line 7 to the first connecting end 3 and the second connecting end 4, improving the stability of the connection. When it is necessary to disassemble or replace the connecting line 7, The connecting line 7 is detached from the first connecting end 3 and the second connecting end 4. By moving the movable block 100 and the connecting line 7 away from the pushing block 105, the movable block 100 pushes the moving block 102 and the moving plate 101 to move. The moving plate 101 drives the telescopic rod 109 to extend. At the same time, the movement of the movable block 100 drives the moving rod 103 and the pressing block 104 to move. The pressing block 104 no longer presses the pushing block 105. Under the action of the first compression spring, the two pushing blocks 105 drive the first rack 106 to move closer to each other. The gear 107 drives the rotating rod to rotate. The second rack 108 drives the telescopic rod 109, the moving plate 101, and the moving block 102 to move away from the connecting line 7, so that the moving block 102 moves into the interior of the mounting groove. The connecting line 7 is no longer restricted, which makes it easier to replace the connecting line 7 and facilitates its use.

[0037] like Figures 9 to 10 As shown, the movable block 100 on the side away from the moving rod 103 and the movable plate 101 on the side away from the movable block 102 are both provided with arc-shaped grooves. The inner wall of the arc-shaped groove is in contact with the outer wall of the connecting line 7. Both sides of the movable block 100 are slidably connected to the inner wall of the moving groove. The movable plate 101 is located inside the moving groove. The side of the movable plate 101 away from the movable block 100 is in contact with the side of the stop block 18.

[0038] The arc-shaped groove facilitates contact with the outer wall of the connecting line 7, improving the stability of the connection line 7. When the connecting line 7 is in contact with the inner wall of the arc-shaped groove, the connecting line 7 is pushed to move the movable block 100 along the inner wall of the moving groove, so that the connecting line 7 can be moved to the bottom of the first connecting end 3 and the second connecting end 4 for installation. At the same time, the moving rod 103 drives the pressing block 104 to move, so that the pushing block 105 drives the first rack 106 to move, so that the gear 107 rotates, and the second rack 108 drives the telescopic rod 109 and the moving plate 101 to move, so that the moving block 102 can move into the moving groove and block the moving groove with the stop block 18, so that the bottom of the protective cover 5 is sealed.

[0039] like Figures 9 to 10As shown, the movable block 102 and the push block 105 are slidably connected to the inner wall of the mounting groove on one side. The first compression spring is located on both sides of the extrusion block 104. Both sides of the extrusion block 104 are in contact with the push block 105 on one side. The rotating rod is rotatably connected to the inner wall of the mounting groove. The push block 105, the first rack 106, the gear 107, the second rack 108, the telescopic rod 109, the movable plate 101, and the movable block 102 are all symmetrically arranged around the center of the movable block 100.

[0040] When the movable rod drives the moving rod 103 to move, the moving rod 103 pushes the pressing block 104 to move along the inner wall of the mounting groove and presses the pushing block 105, so that the pushing block 105 moves away from each other along the inner wall of the mounting groove. When the two sides of the pressing block 104 are in contact with the side of the pushing block 105 near the first spring, the pushing block 105 drives the first rack 106 to move, and the gear 107 drives the rotating rod to rotate and connect along the inner wall of the mounting groove, improving the stability of the rotation of the gear 107. The second rack 108 drives the moving plate 101 to move into the moving groove and limits the connecting line 7. Through the symmetrical arrangement of the first rack 106, gear 107, second rack 108, telescopic rod 109, moving plate 101 and moving block 102, it is convenient to limit the connecting line 7 from both sides of the moving plate 101, further improving the stability of the connecting line 7 and preventing the connecting line 7 from loosening and affecting its use.

[0041] like Figures 9 to 10 As shown, the first rack 106 and the second rack 108 are slidably connected to the inner wall of the mounting groove. The first rack 106 is fixedly installed with a second compression spring 20 at the end away from the gear 107. A fixing block is provided between two adjacent sets of moving plates 101. The fixing block is fixedly installed with the inner wall of the mounting groove. One end of the second compression spring 20 is fixedly installed with the inner wall of the mounting groove, and the other end is fixedly installed with one side of the fixing block.

[0042] When the first rack 106 moves along the inner wall of the mounting groove, the second compression spring 20 is compressed, causing the gear 107 to drive the rotating rod to rotate. The second rack 108 drives the moving plate 101 and the moving block 102 to move. The fixed block facilitates the connection between one end of the connecting spring 17 and the second rack 108. The second compression spring 20 presses against the first rack 106, improving the limiting effect of the moving block 102 on the connecting wire 7. This prevents the connecting wire 7 from being impacted or damaged at the connection points with the first connecting end 3 and the second connecting end 4, thus affecting the stability of the connection. This would prevent poor contact between the connecting wire 7 and the simulator body 1, and the loosening of the connector joints, which could easily cause DC arcing, further reducing the possibility of a fire.

[0043] Working principle: In use, the protective cover 5 is opened by rotating the protective door 6. Rotating the door causes the connecting rod 19 and the stop block 18 to separate from the moving groove. Then, the connecting wire 7 is passed through the moving groove on the first mounting plate 8 and the second mounting plate 9, so that one side of the connecting wire 7 fits into the arc-shaped groove of the movable block 100. Pushing the connecting wire 7 causes the movable block 100 to move. The movable block 100 causes the moving rod 103 and the pressing block 104 to move along the inner wall of the mounting groove, so that the pressing block 104 presses the pushing block 105 away from each other, and makes the first When the compression spring stretches, it pushes the block 105 to move, causing the first rack 106 to move. This causes the gear 107 to rotate the rotating rod, which in turn moves the second rack 108 to move the moving block 102 towards the connecting line 7. The moving block 102 then moves the moving plate 101 into the moving groove and fits against the outside of the connecting line 7, thus confining the connecting line 7 and fixing it to the first mounting plate 8 and the second mounting plate 9. This allows the connecting line 7 to be connected to the first connecting end 3 and the second connecting end 4, respectively. A connecting end 3 is connected to a second connecting end 4. At the same time, the end of the connecting line 7 is limited by the moving plate 101 to prevent the connection between the connecting line 7 and the first connecting end 3 and the second connecting end 4 from being impacted or damaged, which would affect the stability of the connection. After installation, the protective door 6 is rotated to close the protective cover 5. The stop block 18 moves to the moving groove and fits against one side of the moving plate 101, so that the bottom of the first mounting plate 8 and the second mounting plate 9 are sealed. When smoke is generated in the event of a fire at the connection, the smoke alarm 13 will sound an alarm and cut off the power to the simulator. The electromagnetic blocks 15 lose their magnetism and no longer repel each other. The elastic action of the connecting spring 17 drives the two sealing baffles 14 to move closer to each other. When one side of the sealing baffle 14 fits against one side of the fixed plate 16, it blocks the heat dissipation hole, so that the inside of the protective cover 5 is sealed. At the same time, the carbon dioxide gas inside the storage box 11 is delivered to the inside of the protective cover 5 through the delivery pipe 12 to extinguish the fire at the connection. This facilitates the rapid isolation of the connection from the fire source, effectively preventing the spread of the fire and making it easy to use.

[0044] When it is necessary to disassemble or replace the connecting wire 7, disconnect the connecting wire 7 from the first connecting end 3 and the second connecting end 4. By moving the movable block 100 and the connecting wire 7 away from the push block 105, the movable block 100 pushes the moving block 102 and the moving plate 101 to move. The moving plate 101 drives the telescopic rod 109 to extend. At the same time, the movement of the movable block 100 drives the moving rod 103 and the pressing block 104 to move. The pressing block 104 no longer presses the push block 105. Under the action of the first compression spring, the two push blocks 105 drive the first rack 106 to move closer to each other. The gear 107 drives the rotating rod to rotate. The second rack 108 drives the telescopic rod 109, the moving plate 101, and the moving block 102 away from the connecting wire 7, so that the moving block 102 moves into the interior of the mounting groove, no longer restricting the connecting wire 7, thus facilitating the replacement of the connecting wire 7 and making it convenient to use.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
