A multi-port anti-backflow intelligent control terminal

Abstract

This utility model relates to the field of anti-backflow terminal control technology, and discloses a multi-port anti-backflow intelligent control terminal, including a multi-port anti-backflow control device. A fixed outer shell is provided on the outside of the multi-port anti-backflow control device for fixing the device. A first protective mechanism is provided on the outside of the fixed outer shell for protecting the device. A connecting component is provided on one side of the first protective mechanism for sealing the device to the fixed outer shell. When the top plate is impacted, the fork-shaped hinge frame causes the sliding block to slide away from the fixed block. The elastic tension applied by the spring to the second connecting rod further pushes the sliding block towards the fixed block, thus absorbing the impact force generated when the top plate is hit. This prevents the terminal from being damaged by tools, being stepped on, or being struck by falling heavy objects.

Description

Technical Field

[0001] This utility model relates to the field of anti-backflow terminal control technology, specifically, to a multi-port anti-backflow intelligent control terminal. Background Technology

[0002] The multi-port anti-reverse current intelligent control terminal is a device used in distributed generation systems to prevent power backflow. It can monitor and control the power output of multiple ports in real time, ensuring that the photovoltaic power generation system meets local load requirements while preventing excess power from being transmitted to the grid. It is mainly used in industrial and commercial rooftop photovoltaic, park microgrids, distributed photovoltaic power stations and other scenarios to solve the photovoltaic anti-reverse current problem in these scenarios, ensure the stable operation of the power system and improve energy utilization efficiency.

[0003] Multi-port anti-reverse current intelligent control terminals are typically installed outdoors. Outdoor terminals can directly collect the real-time output power of photovoltaic inverters and the current direction of grid-connected cabinets, quickly determine whether there is a risk of reverse current, and issue control commands (such as reducing inverter power or disconnecting the grid-connected switch) within milliseconds or seconds. This ensures a more timely "anti-reverse current" response and avoids signal attenuation and interference problems caused by excessively long cables when the terminal is installed indoors, thus improving control accuracy. However, in places such as photovoltaic power plants and industrial parks, personnel may be performing equipment maintenance, cable laying, and other operations. The exposed terminal may be damaged by tools, being stepped on, or being hit by falling heavy objects. Therefore, those skilled in the art provide a multi-port anti-reverse current intelligent control terminal to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-port anti-backflow intelligent control terminal to solve the problem in the prior art where the terminal may be damaged by tools, stepped on, or hit by falling heavy objects when repairing outdoor terminals.

[0005] This utility model provides the following technical solution: a multi-port anti-backflow intelligent control terminal, including a multi-port anti-backflow control device, a fixed outer shell for fixing the multi-port anti-backflow control device is provided on the outside of the multi-port anti-backflow control device, a first protective mechanism for protecting the multi-port anti-backflow control device is provided on the outside of the fixed outer shell, a connecting component for sealing the multi-port anti-backflow control device and the fixed outer shell is provided on one side of the first protective mechanism, a second protective mechanism for shock absorption is provided on the inside of the first protective mechanism, and an elastic connector for driving the second protective mechanism to quickly reset is provided on one side of the second protective mechanism.

[0006] As a preferred embodiment of the above technical solution, the fixed housing includes a lower frame plate, which is fixedly connected to the lower side of the multi-port anti-backflow control device. A side frame plate is fixedly connected to the upper side of the lower frame plate, and an upper frame plate located on the upper side of the multi-port anti-backflow control device is fixedly connected to the upper side of the side frame plate.

[0007] As a preferred embodiment of the above technical solution, the first protective mechanism includes a sliding frame, which is slidably fitted onto the outside of the side frame plate. A top plate is fixedly connected to the upper end of the sliding frame. The upper surface of the top plate is inclined. Two first guide grooves are opened on both sides of the side frame plate in the length direction. A first guide block is slidably fitted inside each of the four first guide grooves. Multiple first guide blocks are fixedly connected to the inner wall of the top plate on the side near the multi-port anti-backflow control device.

[0008] As a preferred embodiment of the above technical solution, the connecting assembly includes a first fixing plate and a second fixing plate. The first fixing plate is fixedly connected to the upper end of the upper frame plate, and the second fixing plate is fixedly connected to the lower side of the top plate. The second fixing plate has multiple sliding grooves on the side near the first fixing plate, and sliders are slidably fitted inside the multiple sliding grooves. The multiple sliders are fixedly connected to the side of the first fixing plate near the second fixing plate.

[0009] As a preferred embodiment of the above technical solution, the second protective mechanism includes two fixing blocks, which are respectively fixedly connected to the lower end of the top plate and the upper end of the upper frame plate. A fork-shaped hinge frame is hinged between the two fixing blocks. Sliding blocks that are slidably sleeved between the top plate and the upper frame plate are hinged to the other two ends of the fork-shaped hinge frame. A second guide groove is provided at the lower end of the top plate and the upper end of the upper frame plate. A second guide block is slidably sleeved inside each of the two second guide grooves. The two second guide blocks are respectively fixedly connected to the two sliding blocks.

[0010] As a preferred embodiment of the above technical solution, the elastic connector includes a first connecting rod, which is fixedly connected to the side of the fixed block near the sliding block. A second connecting rod is slidably sleeved inside the first connecting rod. The end of the second connecting rod away from the fixed block extends out of the first connecting rod and is fixedly connected to the sliding block. A spring is fixedly connected to the end of the second connecting rod near the fixed block. Two limiting grooves are formed on the inner wall of the first connecting rod. Limiting blocks are slidably sleeved inside each of the two limiting grooves. Both limiting blocks are fixedly connected to the second connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When the top plate is impacted, this utility model uses a fork-shaped hinge frame to make the sliding block slide away from the fixed block. The elastic tension applied by the spring to the second connecting rod also applies an elastic tension to the sliding block to make it slide closer to the fixed block. This absorbs the impact force generated when the top plate is impacted, and prevents the terminal from being hit by tools, stepped on, or hit by falling heavy objects, which would cause damage to the terminal.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figures 1-7 As shown, this utility model provides a technical solution: a multi-port anti-backflow intelligent control terminal, including a multi-port anti-backflow control device 1, a fixed outer shell 2 for fixing the multi-port anti-backflow control device 1 on the outside of the multi-port anti-backflow control device 1, a first protective mechanism 3 for protecting the multi-port anti-backflow control device 1 on the outside of the fixed outer shell 2, a connecting component 4 for sealing the multi-port anti-backflow control device 1 and the fixed outer shell 2 on one side of the first protective mechanism 3, a second protective mechanism 5 for shock absorption on the inside of the first protective mechanism 3, and an elastic connector 6 for driving the second protective mechanism 5 to quickly reset on one side of the second protective mechanism 5.

[0028] The multi-port anti-backflow control device 1 is fixedly installed by the fixed housing 2. When an object falls, the first protective mechanism 3 blocks the object and prevents it from directly hitting the multi-port anti-backflow control device 1. The elastic force applied to the second protective mechanism 5 by the elastic connector 6 supports the first protective mechanism 3 and absorbs the impact force generated by the falling object, thereby reducing the impact force generated when the object falls and protecting the multi-port anti-backflow control device 1.

[0029] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3 As shown, the fixed housing 2 includes a lower frame plate 21, which is fixedly connected to the lower side of the multi-port anti-backflow control device 1. A side frame plate 22 is fixedly connected to the upper side of the lower frame plate 21, and an upper frame plate 23 located on the upper side of the multi-port anti-backflow control device 1 is fixedly connected to the upper side of the side frame plate 22.

[0030] The multi-port anti-backflow control device 1 is fixed in the installation position by using bolts to fix the lower frame plate 21, side frame plate 22 and upper frame plate 23. At the same time, the lower frame plate 21, side frame plate 22 and upper frame plate 23 cover the multi-port anti-backflow control device 1 to prevent objects from directly hitting the multi-port anti-backflow control device 1 and causing damage.

[0031] As one implementation method in this embodiment, please refer to Figures 2-5As shown, the first protective mechanism 3 includes a sliding frame 31, which is slidably sleeved on the outside of the side frame plate 22. A top plate 32 is fixedly connected to the upper end of the sliding frame 31. The upper surface of the top plate 32 is inclined. Two first guide grooves 33 are opened on both sides of the side frame plate 22 in the length direction. A first guide block 34 is slidably sleeved inside each of the four first guide grooves 33. Multiple first guide blocks 34 are fixedly connected to the inner wall of the top plate 32 on the side near the multi-port anti-backflow control device 1. The connecting component 4 includes a first fixing plate 41 and a second fixing plate 42. The first fixing plate 41 is fixedly connected to the upper end of the upper frame plate 23. The second fixing plate 42 is fixedly connected to the lower side of the top plate 32. Multiple sliding grooves 43 are opened on the side of the second fixing plate 42 near the first fixing plate 41. Multiple sliding blocks 44 are slidably sleeved inside each of the multiple sliding grooves 43. Multiple sliding blocks 44 are fixedly connected to the side of the first fixing plate 41 near the second fixing plate 42.

[0032] When an object falls, the top plate 32 blocks it, preventing impact. Simultaneously, the inclined surface of the top plate 32 allows the object to slide along its surface, preventing it from remaining on the top plate after impact and exerting continuous pressure. This protects the device. When the top plate 32 slides, the first guide block 34 guides the sliding frame 31 through the sliding within the first guide groove 33, increasing the uniformity of force on the sliding frame 31 and preventing it from getting stuck due to uneven force. Furthermore, the first fixing plate 41 and the second fixing plate 42 create a sealed space between the top plate 32 and the upper frame plate 23, preventing rainwater from accumulating inside the device during rainy weather.

[0033] As one implementation method in this embodiment, please refer to Figure 2 and Figure 6 As shown, the second protective mechanism 5 includes two fixing blocks 51, which are respectively fixedly connected to the lower end of the top plate 32 and the upper end of the upper frame plate 23. A fork-shaped hinge frame 52 is hinged between the two fixing blocks 51. Sliding blocks 53, which are respectively slidably sleeved between the top plate 32 and the upper frame plate 23, are hinged to the other two ends of the fork-shaped hinge frame 52. A second guide groove 54 is provided at the lower end of the top plate 32 and the upper end of the upper frame plate 23. A second guide block 55 is slidably sleeved inside the two second guide grooves 54. The two second guide blocks 55 are respectively fixedly connected to the two sliding blocks 53.

[0034] When the top plate 32 slides down due to an impact, the sliding block 53 slides away from the fixed block 51 through the fork-shaped hinge frame 52. The elastic tension applied to the second guide block 55 by the elastic connector 6 absorbs the impact force generated when the top plate 32 is hit, thereby reducing the impact force generated when the object hits and protecting the device. When the object slides off the surface of the top plate 32, the elastic tension applied to the sliding block 53 by the elastic connector 6 causes the sliding block 53 to quickly return to its original position, thereby ensuring that the device has continuous protective capabilities. When the sliding block 53 slides, the sliding block 53 is guided by the sliding of the second guide block 55 inside the second guide groove 54 to prevent the sliding block 53 from sliding sideways, making the device more stable.

[0035] As one implementation method in this embodiment, please refer to Figure 6 and Figure 7 As shown, the elastic connector 6 includes a first connecting rod 61, which is fixedly connected to the side of the fixed block 51 near the sliding block 53. A second connecting rod 62 is slidably sleeved inside the first connecting rod 61. The end of the second connecting rod 62 away from the fixed block 51 extends out of the first connecting rod 61 and is fixedly connected to the sliding block 53. A spring 63 is fixedly connected to the end of the second connecting rod 62 near the fixed block 51. Two limiting grooves 64 are opened on the inner wall of the first connecting rod 61. Limiting blocks 65 are slidably sleeved inside the two limiting grooves 64. Both limiting blocks 65 are fixedly connected to the second connecting rod 62.

[0036] The elastic tension applied to the second connecting rod 62 by the spring 63 pulls the sliding block 53 towards the side closer to the fixed block 51, so that the sliding block 53 quickly returns to its original position after the object slides down from the top plate 32. When the second connecting rod 62 slides, the sliding of the limiting block 65 inside the limiting groove 64 limits the second connecting rod 62, preventing the second connecting rod 62 from slipping and causing device failure, thus making the device more stable.

[0037] Working principle: When the top plate 32 is impacted, it slides downwards. The sliding block 53 slides away from the fixed block 51 through the fork-shaped hinge frame 52. The elastic tension applied by the spring 63 to the second connecting rod 62 applies a pulling force to the sliding block 53 towards the fixed block 51, thereby absorbing the impact force generated when the top plate 32 is impacted. This protects the multi-port anti-backflow control device 1 from damage caused by impact. When the sliding block 53 slides, the sliding block 55 slides inside the second guide groove 54 to guide the sliding block 53 and prevent it from sliding sideways. At the same time, the sliding block 34 slides inside the first guide groove 33 to guide the sliding frame 31, increasing the uniformity of the force on the sliding frame 31 and preventing the top plate 32 from getting stuck due to uneven force on the sliding frame 31 during the sliding process.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
