Description

Technical Field

[0001] This utility model relates to the technical field of microcomputer integrated protection devices, specifically to a microcomputer integrated protection device that is easy to maintain. Background Technology

[0002] A "microcomputer-based integrated protection device" is an intelligent electronic device that utilizes microcomputer technology to realize relay protection functions in power systems. It is a digital and intelligent upgrade of traditional electromagnetic or transistor-based relay protection devices. Simply put, you can think of it as an "intelligent bodyguard" or "safety guardian" for power systems (such as substations, power plants, transmission and distribution lines, motors, transformers, capacitors, etc.). The microcomputer-based integrated protection device is one of the core devices for the safe, stable, and reliable operation of modern power systems. It utilizes advanced computer technology and digital signal processing technology to replace traditional relays, achieving intelligent, integrated, and networked protection functions, greatly improving the automation level and safety protection capabilities of power systems.

[0003] The wiring ports of existing microcomputer integrated protection devices are usually located at the rear of the housing. When it is necessary to replace or repair the wires at the wiring ports, it is usually necessary to remove the microcomputer integrated protection device from the cabinet door, which makes the replacement and repair cumbersome and inconvenient.

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0005] The present invention provides a microcomputer-based integrated protection device that is easy to maintain, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A microcomputer-based integrated protection device that is easy to maintain includes a mounting base and a microcomputer-based integrated protection device body mounted on the mounting base. The mounting base has a mounting opening in the middle and a slot at the top of the mounting opening. A retaining plate is provided on the rear wall of the mounting base at the top of the slot, and a retaining groove is formed between the retaining plate and the mounting base. Sliding holes are provided at the four corners of the surface of the mounting base. The microcomputer-based integrated protection device body includes a panel, a housing in the middle of the rear wall of the panel, and sliding rods at the four corners of the rear wall of the panel. The four sliding rods are respectively inserted into the four sliding holes. An insert block is provided at the top of the rear wall of the panel, and a rotating rod is rotatably provided inside the insert block. A locking plate is provided at the rear end of the rotating rod, and the locking plate is rotatably engaged into the retaining groove.

[0008] Preferably, the card plate has an "L" shaped structure.

[0009] Preferably, the front end of the rotating rod is provided with a rotating block, and the surface of the rotating block is provided with several anti-slip grooves.

[0010] Preferably, each of the four corners of the mounting base is provided with a mounting block, and each mounting block has a mounting hole on its surface.

[0011] Beneficial effects

[0012] The above-mentioned technical solutions of one or more of the microcomputer integrated protection devices that are easy to maintain provided by this utility model embodiment have at least one of the following technical effects:

[0013] This utility model, through the above-described technical solution, allows for easy replacement of wires by rotating a rotating block to rotate a rotating rod, causing the locking plate to rotate out of the slot. At this point, pulling the microcomputer integrated protection device body outwards allows it to slide out of the mounting opening. This eliminates the need to completely disassemble the microcomputer integrated protection device body, exposing the rear of the housing and facilitating wire replacement. After replacement, the microcomputer integrated protection device body is pushed into the mounting opening, allowing the insert block to be inserted into the slot. Rotating the rotating rod then causes the locking plate to rotate into the slot for fixation, thus completing the fixation of the microcomputer integrated protection device body and effectively improving maintenance and installation efficiency.

[0024] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.

[0025] like Figure 1-5 The diagram shown is a structural schematic of a microcomputer integrated protection device that is easy to maintain, according to a preferred embodiment of this utility model.

[0026] In this embodiment, a mounting base 1 and a microcomputer integrated protection device body 2 mounted on the mounting base 1 are included. (The basic functions of the microcomputer integrated protection device body 2 are existing technologies and will not be described in detail.) The mounting base 1 has a mounting opening 3 in the middle, a slot 4 at the top of the mounting opening 3, and a retaining plate 5 at the top of the slot 4 on the rear wall of the mounting base 1. A retaining groove 6 is formed between the retaining plate 5 and the mounting base 1. Sliding holes 7, which are circular, are provided at each of the four corners of the surface of the mounting base 1. The microcomputer integrated protection device body 2 includes a panel 8, a housing 9 in the middle of the rear wall of the panel 8, and sliding rods 10 at each of the four corners of the rear wall of the panel 8. The four sliding rods 10 are respectively inserted into the four sliding holes 7. The sliding rods 10 and the sliding holes 7 cooperate to realize a sliding connection structure between the microcomputer integrated protection device body 2 and the mounting base 1. An insert block 11 is provided at the top of the rear wall of the panel 8. The insert block 11 contains... A rotating rod 12 is provided, and a locking plate 13 is provided at the rear end of the rotating rod 12. The locking plate 13 and the rotating rod 12 form a 90-degree angle. The locking plate 13 is rotated and engaged in the slot 6. When it is necessary to disassemble and replace the wire, the rotating rod 12 is rotated by rotating the rotating block 14, so that the locking plate 13 is rotated out of the slot 6. At that time, the microcomputer integrated protection device body 2 is pulled outward, and the microcomputer integrated protection device body 2 slides out from the mounting port 3. Thus, the microcomputer integrated protection device body 2 does not need to be completely disassembled, so that the rear part of the housing 9 is exposed, which facilitates the disassembly and replacement of the wire. After the replacement is completed, the microcomputer integrated protection device body 2 is pushed into the mounting port 3, so that the plug 11 is inserted into the slot 4. Then, the rotating rod 12 is rotated to rotate the locking plate 13 into the slot 6 to fix it. This completes the fixation of the microcomputer integrated protection device body 2, which effectively improves the efficiency of maintenance and installation.

[0027] In this embodiment, the card plate 5 has an "L" shaped structure, which achieves the purpose of forming a slot 6 between the card plate 5 and the mounting base 1.

[0028] In this embodiment, the front end of the rotating rod 12 is provided with a rotating block 14, and the surface of the rotating block 14 is provided with a plurality of anti-slip grooves 15, which increase the surface friction of the rotating block 14.

[0029] In this embodiment, mounting blocks 16 are provided at each of the four corners of the mounting base 1. Mounting holes 17 are provided on the surface of each mounting block 16. Screws are inserted into the mounting holes 17 to fix the mounting blocks 16, thereby fixing the mounting base 1.

[0030] This utility model discloses a microcomputer integrated protection device that is easy to maintain. Its installation method, connection method, or setting method are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0031] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.
