[0002] A fault recording device is a power device that can record the changes in system current, voltage, and their derived quantities, such as active power, reactive power, and system frequency, caused by large disturbances such as short-circuit faults, system oscillations, frequency collapse, and voltage collapse. It is mainly used to detect the operation behavior of relay protection and safety automatic devices, understand the changing patterns of various electrical quantities in the system during transient processes, and verify the correctness of power system calculation programs and model parameters. High-performance fault recording devices play a very important role in ensuring the safe and reliable operation of power systems.
[0003] In modern power fault recording and analysis devices, the device is usually placed in a computer room. Due to the slow airflow in the computer room, dust and impurities in the air can enter the device from the exposed ports due to static electricity. Over time, they will accumulate at the metal contacts, forming dirt, which will increase the contact resistance, causing signal transmission distortion and instability, and even short circuit faults, thus affecting the accuracy of the recorded data. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a power fault recording and analysis device. This device is typically placed in a computer room, where the airflow is slow. Dust and impurities in the air can enter the device through the exposed ports due to static electricity. Over time, these particles accumulate at the metal contacts, causing increased contact resistance, signal transmission distortion and instability, and even short circuits, thus affecting the accuracy of the recorded data.
[0006] (2) Technical solution
[0007] To address the aforementioned technical problems, this utility model provides a power fault recording and analysis device, comprising a main body, portable mechanisms mounted on both sides of the main body, a wire harness storage box on one side of the main body, a display screen on one front side of the main body, and ports on the other front side of the main body.

[0008] Furthermore, the elastic limiting component includes a guide groove, which is opened on the upper and lower sides of the front mounting frame. Front guide shields are slidably provided on both sides of the middle part of the guide groove, and inclined blocks are fixed at the front ends of the two front guide shields. Return springs are installed on both sides of the opposite ends of the two front guide shields. Hand-held blocks are fixed on one side of the front end of the two inclined blocks, and preset grooves for the hand-held blocks to move are opened on both sides of the front end of the front mounting frame.
[0009] Furthermore, the front guide shield and the inclined mounting block at the front end form a movable guide connection along the guide grooves on the upper and lower sides of the middle of the front mounting frame.
[0010] Furthermore, the front guide shield is elastically reset connected to the front mounting bracket using a return spring.
[0011] Furthermore, the sealing assembly includes an insert groove, which is formed at the inner end of one of the front guide frames, and an insert block is fixed at the inner end of the other front guide frame. A sealing gasket is provided on the inner side of the insert groove and the outer side of the insert block.
[0012] Furthermore, the dimensions of the mounting slot and the mounting block are matched.

[0014] (3) Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] When a plug needs to be connected, the operator can hold the plug and align it with the center of the front bracket at the front end of the socket to be inserted. Then, the plug is pressed against the two connected inclined blocks and slowly pushed in. At this time, under the elasticity of the return springs connected to the ends of the front guide shields at the rear ends of the two inclined blocks and the guidance of the guide grooves, the two inclined blocks can move the front guide shields to both sides. When the distance between the middle parts of the two front guide shields matches the size of the plug, the plug can be stably inserted into the socket. At this time, the two front guide shields can continue to elastically press the two sides of the plug under the reset of their respective return springs, thereby indirectly achieving the effect of stabilizing the plug. When the plug needs to be removed, the operator can slightly separate the two holding blocks with the thumb and forefinger of one hand to disengage the connected inclined blocks and front guide shields from the two sides of the plug. At this time, the plug has no restrictive force, making it easy for the operator to remove it. After removal, the two front guide shields will move relative to each other through the return springs. Thus, the insert grooves, insert blocks, and sealing gaskets at the inner ends of the two front guide shields can achieve a stable sealing and dustproof effect at the socket.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This specific embodiment is a power fault recording and analysis device, the structural schematic diagram of which is shown below. Figures 1 to 4As shown, the device includes a main body 1, with portable mechanisms 2 installed on both sides of the main body 1. A wire harness storage box 3 is provided on one side of the main body 1. A display screen 4 is provided on one side of the front of the main body 1, and a socket 5 is provided on the other side of the front of the main body 1. Dustproof protection mechanisms 6 are installed on the front of the multiple sockets 5. The portable mechanism 2 includes a movable hinge 21, which is installed on both sides of the main body 1. A connecting bracket 22 is fixed on one side of the two movable hinges 21, and a buffer sleeve 23 is provided in the middle of the connecting bracket 22. Pads 24 are provided at the four corners of the lower part of the main body 1. The staff can carry the main body 1 of the power fault recording and analysis device by hand using the connecting bracket 22, which is portable and practical.
[0025] The dust protection mechanism 6 includes multiple front mounts 61, which are located at the front ends of multiple ports 5. Elastic limiting components 62 are installed on both sides of the middle portion of each front mount 61. Each elastic limiting component 62 includes a guide groove 621, which is located on the upper and lower sides of the front mount 61. Front guide shields 622 are slidably mounted on both sides of the middle portion of the guide groove 621. An inclined block 623 is fixedly mounted at the front end of each of the two front guide shields 622. The front guide shields 622 and the inclined blocks 623 at their front ends form a movable guide connection along the guide grooves 621 on the upper and lower sides of the middle portion of the front mount 61. Two front guide shields 622 are mounted on opposite ends. A return spring 624 is provided. A handheld block 625 is fixed to one side of the front end of each of the two inclined blocks 623. Pre-set grooves 626 for the handheld blocks 625 to move are provided on both sides of the front end of the front frame 61. The front guide shield 622 is elastically reset connected to the front frame 61 via the return spring 624. Sealing components 63 are installed at the opposite inner ends of the pair of front guide shields 622. Each sealing component 63 includes an insert groove 631, which is located at the inner end of one of the front guide shields 622. An insert block 632 is fixed to the inner end of the other front guide shield 622. Sealing gaskets 6 are provided on the inner side of the insert groove 631 and the outer side of the insert block 632. 33. The dimensions of the mounting slot 631 and the mounting block 632 are matched. When a plug needs to be connected, the operator can hold the plug and align it with the middle of the front bracket 61 at the front end of the socket 5. Then, the plug is pressed against the two joined inclined blocks 623 and slowly pushed in. At this time, under the elasticity of the return spring 624 connected to the end of the front guide bracket 622 at the rear end of the two inclined blocks 623 and the guidance of the guide groove 621, the two inclined blocks 623 can move to both sides with the front guide bracket 622 respectively. When the distance between the middle parts of the two front guide brackets 622 matches the size of the plug, the plug can be stably inserted into the socket 5. At this time, the two front guide brackets 622 are in... Each return spring 624 can continue to elastically press the two sides of the plug after resetting, thereby indirectly stabilizing the plug. When the plug needs to be unplugged, the operator can slightly separate the two hand blocks 625 with the thumb and forefinger of one hand to disengage the inclined blocks 623 and the front guide brackets 622 connected to the plug from the two sides. At this time, the plug is not subject to any restrictive force, making it easy for the operator to unplug it. After unplugging, the two front guide brackets 622 will move relative to each other through the return spring 624. Thus, the mounting grooves 631, mounting blocks 632 and the sealing gaskets 633 at the inner ends of the two front guide brackets 622 can achieve a stable seal and dustproof effect at the socket 5.
[0026] Working principle: The main body 1 of the power fault recording and analysis device can be carried by hand using the connecting bracket 22, making it portable and practical. When a plug needs to be connected, the operator holds the plug and aligns it with the center of the front mounting bracket 61 at the front of the socket 5. Then, the plug is pressed against the two joined inclined blocks 623 and slowly inserted. At this time, under the elasticity of the return springs 624 connected to the ends of the front guide brackets 622 at the rear of the two inclined blocks 623 and the guidance of the guide grooves 621, the two inclined blocks 623 can move the front guide brackets 622 to both sides. When the distance between the middle parts of the two front guide brackets 622 matches the size of the plug, the plug can be stably inserted into the socket 5. At this moment, the two front guide shields 622 can continue to elastically press the two sides of the plug under the reset of their respective return springs 624, thereby indirectly achieving the effect of stabilizing the plug. When the plug needs to be unplugged later, the person can slightly separate the two hand blocks 625 with the thumb and two fingers of one hand so that the inclined blocks 623 and the front guide shields 622 connected to each other can be removed from the two sides of the plug. At this moment, the plug has no restrictive force, which makes it easy for the person to pull it out. After being pulled out, the two front guide shields 622 will move relative to each other through the return springs 624. Thus, the mounting grooves 631, mounting blocks 632 and the sealing gaskets 633 at the inner ends of the two front guide shields 622 can achieve the effect of stable sealing and dust prevention at the plug 5.
