Description
Technical Field
[0001] The present invention relates to the technical field of combiner boxes, and in particular to a combiner box for photovoltaic solar power generation. Background Art
[0002] The combiner box is a wiring device that ensures the orderly connection and convergence function of photovoltaic modules in the photovoltaic power generation system. This device can ensure that the photovoltaic system is easy to cut off the circuit during maintenance and inspection, and reduce the scope of power outage when the photovoltaic system fails. The combiner box means that users can connect a certain number of photovoltaic cells of the same specifications in series to form photovoltaic strings, and then connect several photovoltaic strings in parallel to the photovoltaic combiner box. After the convergence in the photovoltaic combiner box, it is used in conjunction with the controller, DC distribution cabinet, photovoltaic inverter, and AC distribution cabinet to form a complete photovoltaic power generation system and achieve grid connection with the city power.
[0003] When the combiner box is in use, the terminals must not be rusted. When the door of the combiner box is opened and closed, air will enter the combiner box. After the door is closed, if the humidity in the air inside the combiner box is high, the air will oxidize and rust when it encounters the terminals or metal whose temperature is lower than the air temperature, causing various electrical faults in the combiner box. When using photovoltaic solar power generation, the current will fluctuate. When the current is too large, the fuse inside the fuse will melt to protect the circuit. However, solar power plants are generally built in well-lit and remote locations. After the fuse is damaged, maintenance personnel need to be on site to check and replace it in person, which consumes manpower and time. After the fuse is blown, a lot of heat will be generated. If the fuse port of the fuse is not opened, the heat inside the fuse is not easy to be discharged. The heat accumulated inside the fuse will damage the fuse.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention proposes a junction box for photovoltaic solar power generation. In the prior art, if the humidity in the air inside the junction box is high, the air will oxidize and rust when encountering a terminal or metal whose temperature is lower than the air temperature, resulting in various electrical faults in the junction box. In the present invention, the upper air duct is matched with the upper air hole, an exhaust fan is arranged inside the upper air duct, a horizontal air duct is arranged on one side of the upper air duct, a vertical air duct is arranged on one side of the horizontal air duct, a movable cylinder is arranged at the upper end of the vertical air duct, a first cylinder is arranged at the upper end of the movable cylinder, a centrifugal component is arranged inside the movable cylinder, a semiconductor refrigeration sheet is arranged at the bottom of the vertical air duct, a water collecting cylinder is arranged at the bottom of the semiconductor refrigeration sheet, a water pumping component is arranged at the bottom of the water collecting cylinder, and an inlet An air duct, a conical opening is arranged at the upper end of the air inlet pipe, and the conical opening is located inside the water collecting cylinder, one end of the air inlet pipe matches with the side air hole, a centrifugal assembly comprises a motor arranged inside the movable cylinder, the upper end of the motor is connected with the output end of the first cylinder, a first connecting rod is fixedly connected with the output end of the motor, a metal mesh is arranged outside the first connecting rod, and the metal mesh is arranged in three groups, a metal ring is arranged outside the metal mesh, and the metal ring fits with the inner wall of the semiconductor refrigeration plate, a water pumping assembly comprises a water inlet groove arranged at the bottom of the water collecting cylinder, a threaded groove is arranged at the bottom of the water inlet groove, a hard film is arranged inside the water inlet groove, a suction and pressure pipe is arranged at the bottom of the water inlet groove, a threaded joint is arranged at the upper end of the suction and pressure pipe, the threaded joint matches with the threaded groove, and a hard film is arranged inside the suction and pressure pipe. The bottom of the outer box is movably connected with a suction and pressure pad, and the bottom of the suction and pressure pad is fixedly connected with a push-pull rod, and the bottom of the push-pull rod is fixedly connected with an extrusion sheet. When the humidity inside the outer box is too high, the humidity sensor gives a signal to make the exhaust fan and the semiconductor refrigeration sheet work. The exhaust fan makes the air inside the outer box enter the air inlet pipe from the side air holes, and then enter the water collecting cylinder from the conical mouth, and then pass through the metal mesh to enter the vertical air duct and the horizontal air duct, and finally enter the outer box from the upper air duct. After the semiconductor refrigeration sheet works, the temperature of the inner wall of the semiconductor refrigeration sheet will decrease, and the semiconductor refrigeration sheet transfers through the metal ring to reduce the temperature of the metal mesh. When the air inside the outer box passes through the metal mesh with a lower temperature, moisture will condense on the metal mesh. When the humidity of the air inside the outer box decreases Finally, the exhaust fan and the semiconductor refrigeration sheet stop working, and the first cylinder drives the centrifugal assembly to move downward. When the metal mesh moves into the water collecting cylinder, the motor drives the metal mesh to rotate through the first connecting rod. The rotation of the metal mesh throws the dew on the surface into the water collecting cylinder through the centrifugal force. After the dew enters the water collecting cylinder, it accumulates at the bottom of the water collecting cylinder. By pulling the extrusion sheet, the suction and pressure pad makes piston motion inside the suction and pressure tube. When the suction and pressure pad moves downward, the air pressure inside the suction and pressure tube becomes smaller, and the air pressure inside the water collecting cylinder will squeeze the hard film to create gaps in the hard film. At this time, the gas inside the water collecting cylinder will squeeze the water inside the water collecting cylinder into the suction and pressure tube. The suction and pressure tube is removed to discharge the water, thereby reducing the humidity inside the outer box.
[0016] 2. The present invention proposes a junction box for photovoltaic solar power generation. In the prior art, when the current inside the junction box is too large, the fuse inside the fuse will melt to protect the circuit. However, solar power plants are generally built in remote locations with sufficient light. After the fuse is damaged, maintenance personnel need to be on site to check and replace it in person.

After the fuse is blown, the roller rotates to drive the slider to slide inside the slideway, and the slider slides to a suitable position. After that, the cross bar drives the second connecting rod to rotate through the first connecting piece. After the second connecting rod drives the connecting cylinder to move to the appropriate position, the second cylinder drives the first rotating hole to rotate around the rotating rod. When the positioning block moves downward, one end of the bent rod pulls the push-pull block to move outward. At this time, the clip rotates outward through the first connecting rotating block. At this time, the clip is opened. When the positioning block moves upward, the clip closes to clamp the fuse. After one end of the clip clamps the fuse, the other end moves to the side of the baffle. When the clip squeezes the baffle, the baffle slides toward the inside of the plate groove. At this time, the clip opens, and the fuse at one end of the clip will fall into the waste box. The new fuse inside the box body will fall into the clip from the plate groove. The new fuse is blocked by the baffle and stays in the clip. The clip closes to clamp the new fuse and can be placed in the fuse mechanism.

The exhaust fan 22 works to make the air inside the outer box 11 enter the air inlet pipe 29 through the side air hole 112, and then enter the water collecting tube 27 through the tapered mouth 291, and then pass through the metal mesh 253 to enter the vertical air duct 212 and the horizontal air duct 211, and finally enter the outer box 11 through the upper air duct 21. After the semiconductor refrigeration sheet 26 works, the temperature of the inner wall of the semiconductor refrigeration sheet 26 will decrease. The semiconductor refrigeration sheet 26 is transmitted through the metal ring 254 to reduce the temperature of the metal mesh 253. When the air inside the outer box 11 passes through the metal mesh 253 with a lower temperature, moisture will condense on the metal mesh 253. When the humidity of the air inside the outer box 11 decreases, the exhaust fan 22 and the semiconductor refrigeration sheet 26 stop working, and the first air The cylinder 24 drives the centrifugal assembly 25 to move downward. When the metal mesh 253 moves into the water collecting cylinder 27, the first motor 251 drives the metal mesh 253 to rotate through the first connecting rod 252. The rotation of the metal mesh 253 throws the dew on the surface into the water collecting cylinder 27 through the action of centrifugal force. After the dew enters the water collecting cylinder 27, it accumulates at the bottom of the water collecting cylinder 27. By pulling the extrusion sheet 286, the suction pad 284 makes a piston movement inside the suction tube 283. When the suction pad 284 moves downward, the air pressure inside the suction tube 283 becomes smaller, and the air pressure inside the water collecting cylinder 27 will squeeze the hard film 282 to produce a gap in the hard film 282. At this time, the gas inside the water collecting cylinder 27 will squeeze the water inside the water collecting cylinder 27 into the suction tube 283. The suction tube 283 is removed to discharge the water, thereby reducing the humidity inside the outer box 11.
