[0001] This utility model relates to the field of electrical equipment technology, specifically to a nuclear power plant electrical equipment status monitoring device based on wireless transmission. Background Technology

[0002] Electrical equipment testing is a technical activity that uses professional methods and tools to check the performance, safety, and compliance of electrical equipment, ensuring its stable operation and avoiding safety risks. The core of testing is to detect potential equipment hazards in advance, protect personnel and property safety, extend the service life of equipment, and ensure that it meets relevant standards.

[0003] Currently, existing technologies have the following shortcomings: 1. The installation of existing monitoring devices for electrical equipment in nuclear power plants often relies on traditional methods such as manual bolt fixing. The operation steps are cumbersome and the work efficiency is low in the context of limited installation space in nuclear power plants. Moreover, the fixing structure has poor adaptability and is prone to loosening due to factors such as vibration during equipment operation. This cannot guarantee the long-term stable installation of the monitoring device, which may interfere with the accuracy of monitoring data or cause device failure.

[0004] 2. Nuclear power plants contain high-risk environments such as radiation and high pressure. Existing monitoring devices require personnel to make close contact to complete installation, maintenance or dismantling operations, directly exposing them to the risk environment and posing a threat to the personal safety of operation and maintenance personnel. At the same time, manual operation and maintenance processes are time-consuming, which can easily lead to the interruption of electrical equipment status monitoring, making it difficult to respond quickly to monitoring needs and affecting the real-time tracking of equipment operating status and the investigation of potential hazards. Utility Model Content

[0005] The purpose of this invention is to address the problems of complex installation and dismantling operations of existing nuclear power plant electrical equipment monitoring devices and the high-risk environment of nuclear power plants, such as radiation and high voltage, which require personnel to operate, fix, or maintain the devices at close range, posing personnel safety risks. The proposed invention is a nuclear power plant electrical equipment status monitoring device based on wireless transmission.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A wireless transmission-based nuclear power plant electrical equipment condition monitoring device includes a monitor and an external controller. The monitor has a connection mechanism on its outer wall and a snap-fit ​​mechanism on its outer side. The connecting mechanism includes connecting plates symmetrically fixedly connected to the outer wall of the monitor. A mounting shell is slidably connected to one end of the connecting plate away from the monitor. Mounting plates are symmetrically fixedly connected to the outer wall of the mounting shell. A cover plate is fixedly connected to the top of the mounting shell. The snap-fit ​​mechanism includes a drive wheel rotatably connected to the top of the cover plate, a disc fixedly connected to the bottom end of the drive wheel, and a connecting rod fixedly connected to the lower surface of the disc.

[0007] Preferably, there is an electrical connection between the drive wheel and the external controller, the connecting plate has three slots inside, and the bottom of the inner cavity of the mounting shell has two symmetrical sliding grooves.

[0008] Preferably, the snap-fit ​​mechanism further includes a guide rod fixedly connected to the outer wall of the connecting rod, a drive plate slidably connected inside the mounting shell, sliders symmetrically fixedly connected to the bottom end of the drive plate, a spring fixedly connected to the inner wall of the drive plate, an abutment rod symmetrically fixedly connected to the upper surface of the drive plate, a clamping plate slidably connected to the outer wall of the abutment rod, and three locking rods symmetrically fixedly connected to the outer wall of the clamping plate.

[0009] Preferably, the size of the abutment rod is adapted to the size of the slider, and the connecting rod is eccentrically disposed on the lower surface of the disk.

[0010] Preferably, the slider slides within a groove inside the mounting housing, and the two ends of the spring are fixedly connected to the drive plate and the mounting housing, respectively.

[0011] Preferably, the size of the slot inside the connecting plate is adapted to the size of the clamp rod.

[0012] Compared with the prior art, this utility model provides a condition monitoring device for electrical equipment in nuclear power plants based on wireless transmission, which has the following beneficial effects: 1. This wireless transmission-based nuclear power plant electrical equipment condition monitoring device uses a mounting plate to fix the mounting shell, then inserts a monitoring instrument with a connecting plate, and finally drives the snap-fit ​​mechanism through an external controller to make the snap-fit ​​rod accurately embedded in the slot of the connecting plate. The snap-fit ​​rod and the slot are size-matched, and the slider is guided in the sliding groove of the mounting shell to ensure that it is not easy to loosen after installation. It is suitable for nuclear power plant scenarios with limited space and high fixation requirements, and also provides convenience for subsequent disassembly and maintenance.

[0013] 2. This wireless transmission-based nuclear power plant electrical equipment status monitoring device is electrically connected to an external controller via a snap-fit ​​mechanism drive wheel. This allows staff to operate the monitor and automatically fix it without close contact, avoiding risks such as radiation and high voltage from nuclear power plants and ensuring operational safety. Compared to traditional manual fixing methods, automated operation uses the drive wheel to drive the disc, connecting rod, and other components in a coordinated manner, significantly shortening installation and disassembly time, reducing manual steps, improving the efficiency of monitoring device installation, maintenance, or replacement, and reducing monitoring interruption time.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Example: See attached document Figures 1 to 6 As shown, a nuclear power plant electrical equipment status monitoring device based on wireless transmission includes a monitor 101 and an external controller. A connection mechanism 200 is provided on the outer wall of the monitor 101, and a snap-fit ​​mechanism 300 is provided on the outer side of the monitor 101. The connecting mechanism 200 includes a connecting plate 201 symmetrically fixedly connected to the outer wall of the monitor 101. The connecting plate 201 has three slots inside. The end of the connecting plate 201 away from the monitor 101 is slidably connected to a mounting shell 202. The bottom of the inner cavity of the mounting shell 202 has two sliding grooves symmetrically opened. The outer wall of the mounting shell 202 is symmetrically fixedly connected to a mounting plate 203. The top of the mounting shell 202 is fixedly connected to a cover plate 204. The snap-fit ​​mechanism 300 includes a drive wheel 301 rotatably connected to the top of the cover plate 204. The drive wheel 301 is electrically connected to an external controller. A disc 302 is fixedly connected to the bottom end of the drive wheel 301. A connecting rod 303 is fixedly connected to the lower surface of the disc 302. The connecting rod 303 is eccentrically disposed on the lower surface of the disc 302.

[0019] Furthermore, the snap-fit ​​mechanism 300 also includes a guide rod 304 fixedly connected to the outer wall of the connecting rod 303, a drive plate 305 slidably connected inside the mounting shell 202, a slider 306 symmetrically fixedly connected to the bottom end of the drive plate 305, the slider 306 sliding in a groove opened inside the mounting shell 202, a spring 307 fixedly connected to the inner wall of the drive plate 305, the two ends of the spring 307 being fixedly connected to the drive plate 305 and the mounting shell 202 respectively, an abutment rod 308 symmetrically fixedly connected to the upper surface of the drive plate 305, the size of the abutment rod 308 being adapted to the size of the slider 306, a clamping plate 309 slidably connected to the outer wall of the abutment rod 308, three locking rods 310 symmetrically fixedly connected to the outer wall of the clamping plate 309, and the size of the slot opened inside the connecting plate 201 being adapted to the size of the locking rods 310.

[0020] When using this utility model, First, the operator connects the mounting housing 202 to the mounting base via the mounting plate 203. Then, the monitor 101, equipped with the connecting plate 201, is inserted into the mounting housing 202. Next, the operator controls the drive wheel 301 via an external controller, causing it to rotate synchronously within the cover plate 204. This rotation drives the disc 302, which in turn causes the connecting rod 303, connected to its lower surface, to rotate eccentrically. This, in turn, causes the guide rod 304 to move synchronously via the connecting rod 303. The guide rod 304 then moves the drive plate 305, which is rotatably connected to it, synchronously within the mounting housing 202. The movable plate 305 drives the slider 306 to move within the groove opened inside the mounting shell 202. When the disc 302 drives the connecting rod 303 to move towards the side closer to the drive wheel 301, the connecting rod 303 pulls the guide rod 304 and the drive plate 305 to move synchronously. This causes the drive plate 305 to compress the spring 307 towards the side closer to the drive wheel 301, and causes the drive plate 305 to drive the abutment rod 308 to move synchronously. This causes the abutment rod 308 to abut the slider 306, causing the slider 306 to drive the clamping plate 309 to move laterally inside the mounting shell 202. This causes the clamping plate 309 to drive the locking rod 310 into the slot opened on the side wall of the connecting plate 201, thereby achieving a fixing effect.

[0021] The mounting shell 202 is fixed by the mounting plate 203, and then the monitoring instrument 101 with the connecting plate 201 is inserted. Finally, the locking mechanism 300 is driven by the external controller so that the locking rod 310 is accurately embedded into the slot of the connecting plate 201. The locking rod 310 and the slot are size-matched, and the slider 306 is guided in the sliding groove of the mounting shell 202 to ensure that it is not easy to loosen after installation. It is suitable for the scenario of limited space and high fixation requirements in nuclear power plants, and also provides convenience for subsequent disassembly and maintenance.

[0022] The drive wheel 301 of the snap-fit ​​mechanism 300 is electrically connected to the external controller, allowing staff to operate the monitor 101 to be automatically fixed without close contact, thus avoiding the risks of radiation and high voltage from nuclear power plants and ensuring operational safety. Compared with the traditional manual fixing method, the automated operation uses the drive wheel 301 to drive the disc 302, connecting rod 303 and other components to move together, which greatly shortens the installation and disassembly time, reduces manual steps, improves the efficiency of installation, maintenance or replacement of monitoring devices, and reduces the duration of monitoring interruption.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
