Description

Technical Field

[0001] This utility model relates to the field of inverter protection technology, and in particular to a protection structure for inverters. Background Technology

[0002] The rapid development of new energy technologies has led to the widespread application of inverters in photovoltaic, wind power, and other fields. As a crucial device for converting direct current (DC) to alternating current (AC), inverters face various environmental challenges during operation, such as temperature fluctuations, humidity, dust, corrosive gases, and electromagnetic interference. These factors threaten the performance and lifespan of inverters, necessitating the design of effective protective structures to enhance their reliability and stability. Currently, inverter protective structures typically include several aspects. First, the selection of the casing material is critical, often employing corrosion-resistant and high-temperature-resistant materials such as aluminum alloys and engineering plastics to withstand external environmental stresses. Second, the inverter's sealed design effectively prevents the intrusion of water and dust; common protection ratings include IP65 or higher to meet stringent environmental requirements. Furthermore, heat dissipation management is equally important, employing air-cooling or liquid-cooling technologies and heat sink designs to ensure the inverter maintains a stable operating temperature under high power output conditions.

[0003] During use, inverter protection structures are necessary because power cords need to be connected to the inverter. If the power cords connected to the inverter cannot be securely clamped, they will come off and become unusable once pulled. Utility Model Content

[0004] This utility model relates to a protective structure for an inverter. The protective outer shell protects the inverter inside, while the anti-slip grooves on the concave surfaces of two limiting plates securely clamp the power cord connected to the inverter. Furthermore, the concave surfaces of the two clamping plates also clamp the power cord at the inverter's connector. Simultaneously, the two clamping plates also block and restrict the connector at the inverter's connector, effectively preventing the power cord from coming loose due to pulling or vibration during use, ensuring the normal operation of the inverter. The design of the two clamping plates not only clamps the power cord but also provides physical obstruction of the connector, effectively reducing shaking and loosening at the connector and improving connection stability, thus effectively protecting the connecting wires on the inverter.

[0005] In a first aspect, this utility model provides a protective structure for an inverter, specifically comprising: a protective housing; two handles fixedly installed at the top of the protective housing; four threaded grooves opened at the bottom of the inner sidewall of the protective housing; sealing doors installed on both sides of the protective housing, and through screws inserted at the four corners of the sealing doors; and a stabilizing plate installed at the bottom inside the protective housing, with through bolts inserted at the four corners of the stabilizing plate.

[0006] A cantilever frame is fixedly installed on the left side wall of the sealing door at the right end of the protective shell, and threaded holes are opened at both ends of the cantilever frame; side plates are fixedly installed at both ends of the right end of the cantilever frame, and two through screws are inserted into the side plates; an adjustment hole is opened at the right end of the cantilever frame, and a limiting rod is inserted into the adjustment hole; symmetrical limiting rings are rotatably fitted on the two limiting rods.

[0007] An arc-shaped limiting plate is fixedly installed at one end of each of the two limiting rods facing each other, and an anti-slip groove is provided on the concave surface of the limiting plate. Two slots are provided at both ends of the front sidewall of the rear limiting plate, and two inserts are fixedly installed at both ends of the rear sidewall of the front limiting plate. Four through guide holes are provided at the left end of the cantilever frame. Through adjusting rods are rotatably inserted into the two threaded holes of the cantilever frame, and threads are provided on the outer annular sidewall of the adjusting rod.

[0008] Bearing rings are fixedly installed at opposite ends of the two adjusting rods; anti-detachment rings are rotatably fitted on the side walls of the two adjusting rods; arc-shaped clamping plates are fixedly installed on the outer rings at opposite ends of the two bearing rings, and four guide rods are fixedly installed on the side walls of the clamping plates.

[0009] Furthermore, the protective shell has closed slots at both ends, and through heat dissipation holes are evenly distributed on both sides of the protective shell. A sealing plate is inserted into each of the two closed slots.

[0010] Furthermore, a through-hole is provided in the middle of the sealing door on the right end of the protective shell, and a sealing ring is installed at the left end of the through-hole.

[0011] Furthermore, a support frame is fixedly installed on the stabilizer plate, and a slot is provided at the upper end of the support frame, where an inverter is installed.

[0012] This utility model provides a protection structure for an inverter, which has the following beneficial effects:

[0013] In this utility model, the protective structure protects the inverter inside the outer shell, while the anti-slip grooves on the concave surfaces of the two limiting plates firmly clamp the power cord connected to the inverter. The concave surfaces of the two clamping plates also clamp the power cord at the inverter's connector. Simultaneously, the two clamping plates also block and restrict the connector at the inverter's connector, effectively preventing the power cord from coming loose due to pulling or vibration during use, ensuring the normal operation of the inverter. The design of the two clamping plates not only clamps the power cord but also provides physical obstruction to the connector, effectively reducing shaking and loosening at the connector and improving connection stability, thus effectively protecting the connecting wires on the inverter.

[0014] By pulling the sealing plate upwards from the sealing slot, the heat dissipation holes on the protective shell become open, allowing the heat generated by the inverter during operation to be discharged outwards through these holes. This design ensures good heat dissipation during inverter operation, improving its operational stability and safety. After the inverter is finished, the sealing plate is inserted back into the sealing slot to block and seal the heat dissipation holes, preventing external debris from entering the protective shell through the holes and thus avoiding its adhesion to the inverter, which would affect heat dissipation efficiency and normal operation of the equipment. At the same time, this design also improves the durability and reliability of the equipment. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1 to 4 :

[0025] This utility model proposes a protective structure for an inverter, including: a protective housing 1; two handles fixedly installed on the top of the protective housing 1; the handles facilitate movement of the entire device; four threaded grooves are formed on the bottom of the inner wall of the protective housing 1; sealing doors are installed on both sides of the protective housing 1, and through screws are inserted into the four corners of the sealing doors; the screws on the sealing doors are rotated and inserted into the two side walls of the protective housing 1, thus installing the two sealing doors on the two side walls of the protective housing 1; sealing grooves 101 are formed at both ends of the protective housing 1; and through heat dissipation holes 10 are evenly formed on both sides of the protective housing 1. 2. Two sealing plates 103 are respectively installed in the two sealing slots 101. When the inverter 203 is in use, the sealing plates 103 are moved upward from the sealing slots 101 and pulled out. At this time, the heat dissipation holes 102 on the protective shell 1 will be open, and the heat generated by the inverter 203 during operation will be discharged outward through the heat dissipation holes 102, which facilitates heat dissipation of the inverter 203 and avoids short circuits, thus protecting the inverter 203. After the inverter 203 is finished, the sealing plates 103 are inserted into the sealing slots 101 to block and seal the heat dissipation holes 102, preventing external debris from entering the protective shell 1 through the heat dissipation holes 102. Inside the protective casing 1, the wires adhere to the inverter 203, affecting heat dissipation. A through-hole 104 is provided in the middle of the right-side sealing door of the protective casing 1, and a sealing ring 105 is installed at the left end of the through-hole 104. The sealing ring 105 has a looseness / tightness; it is used to seal the through-hole 104. The external power cable enters through the through-hole 104, and then the sealing ring 105 at the through-hole 104 is placed on the power cable. Next, the connector on the power cable is plugged into the inverter 203 to connect the power supply. A stabilizing plate 2 is installed at the bottom inside the protective casing 1, and through bolts are inserted at the four corners of the stabilizing plate 2. The stabilizing plate 2... Bolts are inserted into the threaded grooves at the bottom of the protective housing 1 to fix and restrict the stabilizing plate 2 and the support frame 201. The support frame 201 will not move when touched, so the support frame 201 can stably support the inverter 203. The support frame 201 is fixedly installed on the stabilizing plate 2, and the upper end of the support frame 201 has a slot 202, and the inverter 203 is clamped in the slot 202. The lower end of the inverter 203 is clamped in the slot 202 to stabilize the inverter 203. A cantilever frame 3 is fixedly installed on the left side wall of the right end sealing door of the protective housing 1, and threaded holes are opened at both ends of the cantilever frame 3.

[0026] The cantilever frame 3 has two side plates 301 fixedly installed at its right ends. Two through screws are inserted into each side plate 301. Rotating these screws onto the sealing door at the right end of the protective housing 1 secures the side plates 301 and the cantilever frame 3, preventing movement or falling when the cantilever frame 3 is touched. A through adjustment hole 302 is provided at the right end of the cantilever frame 3, and a through limiting rod 303 is inserted into this hole. Two symmetrical limiting rings 304 are rotatably fitted onto each limiting rod 303. Rotating the two limiting rings 304 on the limiting rods 303 and moving them in opposite directions allows the two limiting plates 305 to be moved towards each other, thus securing the two limiting plates. When the plates 305 are joined together, the insert block 307 will be inserted into the slot 306. Simultaneously, the anti-slip grooves on the concave surfaces of the two limiting plates 305 will press against the surface of the power cord. Then, the two limiting rings 304 are rotated and moved in opposite directions to adhere to and tighten against the inner and outer walls of the cantilever frame 3, fixing and restricting the limiting rods 303 and the limiting plates 305. At this time, the two limiting plates 305 will temporarily clamp and restrict the power cord, preventing it from falling off when pulled. Arc-shaped limiting plates 305 are fixedly installed at opposite ends of the two limiting rods 303, and the concave surfaces of the limiting plates 305 have anti-slip grooves. Two slots 306 are respectively opened at both ends of the front sidewall of the rear limiting plate 305, and the rear sidewall of the front limiting plate 305... Two plug blocks 307 are fixedly installed at each end. Four through guide holes 308 are opened at the left end of the cantilever frame 3. Through adjusting rods 309 are rotatably inserted into the two threaded holes of the cantilever frame 3, and threads are opened on the outer annular sidewall of the adjusting rods 309. Bearing rings 310 are fixedly installed at the opposite ends of the two adjusting rods 309. Anti-detachment rings 311 are rotatably fitted on the sidewalls of the two adjusting rods 309. After the connector on the power cord is inserted into the inverter 203, the clamping plates 312 are rotated and moved in opposite directions by the two adjusting rods 309. The concave surfaces of the two clamping plates 312 are used to firmly clamp the power cord. Then the two anti-detachment rings 311 are rotated and moved in opposite directions by the sidewalls of the anti-detachment rings 311 and the cantilever frame 308. The side walls of the two clamping plates 312 are pressed together, and the left side wall of the two clamping plates 312 is in contact with the right side wall of the power cord connector, which restricts the connector and prevents the power cord from falling off when pulled. This protects the connector and the inverter 203 socket. The outer rings of the two bearing rings 310 are fixedly installed with arc-shaped clamping plates 312 at opposite ends, and four guide rods 313 are fixedly installed on the side wall of the clamping plates 312. The guide rods 313 slide through the guide holes 308. When the clamping plates 312 slide back and forth, the guide rods 313 are restricted by the guide holes 308, and the clamping plates 312 can only slide back and forth to prevent the clamping plates 312 from tilting when sliding back and forth. Otherwise, the concave surfaces of the two clamping plates 312 will not be able to stably clamp the power cord.

[0027] Example 2, based on Example 1, such as Figure 1 and Figure 4 As shown, a stabilizing plate 2 is installed at the bottom inside the protective shell 1, and through bolts are inserted at the four corners of the stabilizing plate 2. After removing the stabilizing plate 2 and the bolts, the support frame 201 is fixedly welded to the protective shell 1 to stabilize and restrict the support frame 201. This way, the support frame 201 will not tilt when touched, thus saving the cost of parts.

[0028] The working principle of this embodiment is as follows: In use, the two limiting rings 304 on the limiting rod 303 are rotated and moved in opposite directions. Then, the two limiting rods 303 are moved towards each other, and the two limiting plates 305 are then aligned. At this time, the insert block 307 will be inserted into the slot 306. Simultaneously, the anti-slip grooves on the concave surfaces of the two limiting plates 305 will press against the surface of the power cord. Next, the two limiting rings 304 are rotated and moved in opposite directions to adhere to and tighten against the inner and outer walls of the cantilever frame 3, thus fixing and restricting the limiting rods 303 and the limiting plates 305. At this time, the two limiting plates 305 will temporarily clamp and restrict the power cord. The two adjusting rods 309 are rotated and moved in opposite directions, and the concave surfaces of the two clamping plates 312 firmly clamp the power cord. Then, the two anti-detachment rings 311 are rotated and moved in opposite directions, and the side walls of the anti-detachment rings 311 are aligned with the cantilever frame 3. When the side walls are pressed together, the left side wall of the two clamping plates 312 is in contact with the right side wall of the power cord connector, obstructing and restricting the connector. This prevents the power cord from coming off when pulled, thus protecting the connector and the inverter 203 socket. When the inverter 203 is in use, the sealing plate 103 is moved upward from the sealing groove 101 and pulled out. At this time, the heat dissipation holes 102 on the protective shell 1 will be open, and the heat generated by the inverter 203 during operation will be discharged outward from the heat dissipation holes 102, facilitating heat dissipation and preventing short circuits, thus protecting the inverter 203. After the inverter 203 is finished, the sealing plate 103 is inserted into the sealing groove 101 to block and seal the heat dissipation holes 102, preventing external debris from entering the protective shell 1 through the heat dissipation holes 102 and adhering to the inverter 203, affecting heat dissipation.
