Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-voltage surge protection technology, and in particular to an online monitoring device for low-voltage surge protection. Background Technology
[0002] With the development of smart grid and Internet of Things technologies, higher requirements have been placed on the safety and reliability of power systems. As a result, low-voltage surge protection online monitoring devices have emerged. These devices can promptly detect and address potential problems by monitoring the operating status and performance parameters of low-voltage surge protectors in real time, thereby improving the safety and reliability of power systems.
[0003] A search revealed that the invention with announcement number CN118707216A relates to the field of surge protector monitoring technology, specifically to an online monitoring system for low-voltage surge protection.
[0004] 1. When installing the low-voltage surge protection online monitoring system, a motor-driven steering and an electric telescopic cylinder are used for clamping. However, the low-voltage surge protection online monitoring system is a small device. Due to its small size, it is already compact and easy to install. Using a motor and an electric telescopic cylinder will not only increase the power cost but also the manufacturing cost of the device.
[0005] 2. The turntable of this low-voltage surge protection online monitoring system is directly fixed to one end of the coupling, and the turntable is supported by the coupling. Because the bearing area at the bottom of the turntable is small and the bearing capacity is poor, it is easy to affect the stability of the turntable support. Utility Model Content
[0006] The purpose of this utility model is to address the shortcomings of existing technologies, such as the small size of the device itself, which makes it easy to install, but the use of motors and electric telescopic cylinders not only increases the electricity cost but also the manufacturing cost of the device. Furthermore, the small bearing area at the bottom of the turntable results in poor bearing capacity, which can easily affect the stable support of the turntable. Therefore, this utility model proposes a low-voltage surge protection online monitoring device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A low-voltage surge protection online monitoring device includes a base, with each of the four corners of the base fixed at a designated position by screws. A rotating plate is provided on the top of the base, and a nut is provided on the top of the rotating plate. The device body is placed on the top of the nut. A worm gear is rotatably connected inside the base, and a worm is rotatably connected inside the base, with one end of the worm extending to one side of the base. The worm gear meshes with the worm.
[0009] In one possible design, a bottom ring is fixedly connected to the bottom of the rotating plate, a bottom groove is provided at the top of the base, and the bottom ring rotates within the bottom groove. A rotating shaft is fixedly connected to the top of the worm gear, and one end of the rotating shaft extends into the bottom groove and is fixedly connected to the bottom of the rotating plate.
[0010] In one possible design, the rotating plate has multiple through slots, a connecting shaft is fixedly connected in each through slot, two arc-shaped clamps are provided in each through slot, and the connecting shaft rotates through the two arc-shaped clamps. A torsion spring is fixedly connected between the two arc-shaped clamps and is sleeved on the outer wall of the connecting shaft.
[0011] In one possible design, the rotating plate has an L-shaped annular groove, the bottom of the nut is fixedly connected to an L-shaped ring, and the L-shaped ring rotates within the L-shaped annular groove. The bottom of the device body is fixedly connected to a fixing column, and the outer wall of the fixing column is threaded. The inner wall of the nut is threadedly connected to the outer wall of the fixing column.
[0012] In one possible design, the bottom of the rotating plate is provided with multiple spherical seats, which are inserted into the through groove. The tops of the two arc-shaped clamps are provided with arc-shaped openings, and the two arc-shaped openings fit together in a conical shape. The bottom of the spherical seats touches the two fitting arc-shaped openings.
[0013] In one possible design, the spherical seat is fixedly connected to the bottom of the fixed column by a connecting column, and the diameter of the connecting column is smaller than the diameter of the spherical seat.
[0014] In this application, during installation, the base is fixed to the installation position with bolts. The worm gear is manually driven to rotate the worm wheel, which in turn rotates the rotating plate. The bottom ring of the rotating plate is located in the bottom groove for support, thereby adjusting the required installation angle of the device. After adjustment, the device body is inserted into the through groove through multiple ball seats at the bottom and pressed into the arc-shaped openings at the top of two mutually fitting arc-shaped clamps. The nut is rotated, and the L-shaped ring at the bottom of the nut rotates in the L-shaped ring groove. The nut is threadedly connected to the fixing post at the bottom of the device body. The device body slowly descends, and the bottom of the ball seats pushes the arc-shaped openings, causing the two arc-shaped clamps to open away from each other through the connecting shaft. The ball seats are slowly inserted between the two arc-shaped clamps. As the ball seats descend to the bottom of the inner wall of the two arc-shaped clamps, the torsion springs connected between the two arc-shaped clamps and the connecting shaft reset and push the two arc-shaped clamps to clamp the ball seats. At the same time, the nut is tightened between the fixing post, achieving a double fixing effect.
[0015] Beneficial effects: In this utility model, the low-voltage surge protection online monitoring device drives the worm gear to rotate by manually driving the worm, which in turn drives the rotating plate and its components to rotate. The manual adjustment method is not only more flexible, but also effectively reduces manufacturing costs. This design enables the device to adapt to the needs of different installation environments and effectively improves the flexibility and adaptability of installation.
[0016] In this utility model, the low-voltage surge protection online monitoring device uses multiple spherical seats inserted into two arc-shaped clamps, which are then connected to the fixed column at the bottom of the device body with nuts. This enables quick and convenient assembly, which simplifies the installation process and improves installation efficiency.
[0017] This invention offers several advantages, including flexible installation angle adjustment, a stable support structure, convenient assembly, a dual fixing mechanism, and improved monitoring accuracy. These benefits make the device widely applicable and valuable in the field of lightning protection monitoring. Attached Figure Description

The bottom of the rotating plate 3 is fixedly connected to the rotating shaft at the top of the worm gear 6, so that the rotation of the worm gear 6 can drive the rotating plate 3 to rotate.
[0026] Reference Figure 2 and Figure 3 The rotating plate 3 has multiple through slots 8, and a connecting shaft 12 is fixedly connected to each through slot 8. Two arc-shaped clamping plates 9 are located within each through slot 8, and the connecting shaft 12 rotatably passes through the two arc-shaped clamping plates 9. A torsion spring is fixedly connected between the two arc-shaped clamping plates 9, and the torsion spring is sleeved on the outer wall of the connecting shaft 12. The two arc-shaped clamping plates 9 rotate within the through slots 8 via the connecting shaft 12, and the torsion spring provides clamping force between the two arc-shaped clamping plates 9.
[0027] Reference Figure 4 The rotating plate 3 has an L-shaped annular groove 14. An L-shaped ring 16 is fixedly connected to the bottom of the nut 15, and the L-shaped ring 16 rotates within the L-shaped annular groove 14.
