Description
Technical Field
[0001] This utility model relates to the field of grounding line selection technology, and more specifically, to a microcomputer-based low-current grounding line selection device. Background Technology
[0002] Low-current grounding systems are widely used in power systems, and microcomputer-based low-current grounding fault location devices are crucial for timely and accurate identification of grounding fault lines.
[0003] However, existing grounding line selection devices have relatively fixed installation methods, lack flexibility, and are difficult to adapt to different installation environments and working requirements. In practical applications, due to the limitation of the installation location, the installation and adjustment of the device may be difficult, affecting its normal operation. In addition, traditional devices also have shortcomings in positioning and fixing, which may loosen or shift during operation, affecting the accuracy of grounding line selection.
[0004] Therefore, we have made improvements to this and proposed a microcomputer-based low-current grounding fault location device. Utility Model Content
[0005] The purpose of this utility model is to address the problems raised in the existing background technology.
[0006] In order to achieve the above-mentioned objectives, this utility model provides a microcomputer-based low-current grounding selection device to improve the above-mentioned problems.
[0007] The application is as follows:
[0008] A microcomputer-based low-current grounding fault location device includes a grounding fault location device body. An adjustment assembly is provided on the grounding fault location device body. The adjustment assembly includes an adjustment mechanism and a positioning mechanism. The adjustment mechanism includes an adjustment slide rail, a magnetic mounting plate, and support blocks. Two adjustment slide rails are mounted on the grounding fault location device body. The magnetic mounting plate and two support blocks are both connected to the adjustment slide rails. Two adjustment supports are mounted on the magnetic mounting plate. An adjustment base is mounted on each adjustment support. Multiple return springs are installed between the adjustment base and the adjustment supports.
[0009] As a preferred technical solution of this application, the positioning mechanism includes a positioning plate and positioning protrusions. The positioning plate and positioning protrusions are both mounted on a magnetic mounting plate.

[0010] As a preferred technical solution of this application, the magnetic mounting plate is provided with a reset mechanism, and the magnetic mounting plate and the positioning plate achieve the effect of reset through the reset mechanism.
[0011] As a preferred technical solution of this application, the reset mechanism includes a positioning rod, a second reset spring, and an elastic support plate. The plurality of positioning rods are connected to the magnetic mounting plate, and the second reset spring is sleeved on the positioning rod with its two ends respectively installed on the magnetic mounting plate and the positioning plate.
[0012] As a preferred technical solution of this application, two elastic support plates are installed on the magnetic mounting plate. The two elastic support plates are distributed in a triangular shape, and a rubber pad is installed at the connection between the two elastic support plates and the magnetic mounting plate.
[0013] As a preferred technical solution of this application, the adjusting slide rail is connected to two side mounting strips that are installed on the grounding line selection device body by screws. One of the side mounting strips has multiple holes, and the positioning protrusion is located in three of the holes.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In the scheme of this application:
[0016] 1. In order to solve the problem that the installation method in the prior art is relatively fixed, lacks flexibility, and is difficult to adapt to different installation environments and working requirements, this application sets an adjustment mechanism to enable the grounding line selection device body to be adjusted in the horizontal direction to adapt to different installation environments and usage requirements.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0028] As described in the background section, the installation method is relatively fixed, lacks flexibility, and is difficult to adapt to different installation environments and work requirements.
[0029] To solve this technical problem, this utility model provides a microcomputer-based low-current grounding line selection device, which is applied to adjustment and installation.
[0030] For details, please refer to Figures 1-3A microcomputer-based low-current grounding fault location device includes a grounding fault location device body 1. An adjustment component 2 is mounted on the grounding fault location device body 1. The adjustment component 2 includes an adjustment mechanism 20 and a positioning mechanism 21. The adjustment mechanism 20 includes an adjustment slide rail 201, a magnetic mounting plate 202, and support blocks 203. Two adjustment slide rails 201 are mounted on the grounding fault location device body 1. The magnetic mounting plate 202 and the two support blocks 203 are both connected to the adjustment slide rails 201. Two adjustment supports 204 are mounted on the magnetic mounting plate 202. An adjustment base 205 is mounted on the adjustment support 204. Multiple reset springs 206 are installed between the adjustment base 205 and the adjustment support 204.
[0031] When the grounding selection device body 1 is in operation, its position and angle can be adjusted via the adjustment component 2. In the adjustment mechanism 20, the magnetic mounting plate 202 and the support block 203 can slide on the adjustment slide rail 201 to achieve horizontal position adjustment. Multiple return springs 206 are installed between the adjustment support 204 and the adjustment base 205 on the magnetic mounting plate 202. When subjected to external force, the adjustment base 205 can move and change its angle relative to the adjustment support 204 to a certain extent. After the external force disappears, the return springs 206 can help the adjustment base 205 return to its initial position, achieving a certain buffering and adaptive adjustment function. The positioning mechanism 21 can fix the entire device after adjustment to ensure the stability of the device during operation.
[0032] The present invention provides a microcomputer-based low-current grounding line selection device. The adjustment mechanism 20 enables the grounding line selection device body 1 to be adjusted in the horizontal direction to adapt to different installation environments and usage requirements. The magnetic mounting plate 202 can be used to easily install the device on a metal surface, improving the installation flexibility. The support block 203 provides additional support for the device and enhances its stability.
[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0034] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0036] Please refer to Figures 3-5A microcomputer-based low-current grounding selection device includes a positioning mechanism 21 comprising a positioning plate 210 and positioning protrusions 211. Both the positioning plate 210 and the positioning protrusions 211 are mounted on a magnetic mounting plate 202. Multiple positioning protrusions 211 are arranged in groups of three at the position of the positioning plate 210. A handle 212 is mounted on the positioning plate 210 and located within the magnetic mounting plate 202. Two side mounting strips, which are screwed to the grounding selection device body 1, are connected to an adjusting slide rail 201. One of the side mounting strips has multiple holes, and the positioning protrusions 211 are located in three of these holes. The adjusting slide rail 201 of the adjusting mechanism 20... 01 is connected to the grounding selection device body 1 via the side mounting strip. When the device position needs to be adjusted, the magnetic mounting plate 202 and other components can be moved along the adjustment slide rail 201. The positioning plate 210 and positioning protrusion 211 in the positioning mechanism 21 are installed on the magnetic mounting plate 202. After the position is determined, the positioning plate 210 is pulled by the handle 212, so that the positioning protrusion 211 is engaged in the hole on the side mounting strip to achieve positioning. Among them, multiple positioning protrusions 211 are in groups of three, which can more stably cooperate with the hole to ensure that the device is firmly fixed, so as to position the magnetic mounting plate 202 after the position is adjusted and avoid displacement.
[0037] The positioning protrusions 211, which are designed to engage with the holes on the side mounting strip, provide clear positioning points, ensuring that the device can be accurately fixed in the required position after adjustment. The three positioning protrusions 211 in a group increase the stability of positioning and prevent the device from shaking or shifting during operation.
[0038] Please refer to Figure 3 and Figure 4 A microcomputer-based low-current grounding selection device includes a reset mechanism 22 on its magnetic mounting plate 202. The magnetic mounting plate 202 and the positioning plate 210 are reset via the reset mechanism 22. The reset mechanism 22 includes positioning rods 220, a second reset spring 221, and an elastic support plate 222. Multiple positioning rods 220 are connected to the magnetic mounting plate 202, and the second reset spring 221 is sleeved on the positioning rods 220 with its two ends respectively attached to the magnetic mounting plate 202 and the positioning plate 210. When the handle 212 is used... When the positioning plate 210 is pulled to disengage the positioning protrusion 211 from the hole on the side mounting strip for position adjustment, the second return spring 221 is compressed on the positioning rod 220. When the adjustment is completed and positioning is required, the handle 212 is released. Under the elastic restoring force of the second return spring 221, the positioning plate 210 is pushed back to the initial position, so that the positioning protrusion 211 is once again inserted into the corresponding hole to achieve positioning. The elastic support plate 222 plays an auxiliary support and buffering role in this process to ensure that the resetting process is carried out smoothly.
[0039] The reliability of positioning is ensured by the setting of the reset spring 221. During the operation of the device, even if it is affected by certain external forces or vibrations, the reset spring 221 can always keep the positioning plate 210 in a stable positioning state, preventing the positioning protrusion 211 from accidentally dislodging from the hole. The positioning rod 220 provides a stable guiding effect for the reset spring 221, ensuring that the spring will not be deflected or twisted during compression and recovery.
[0040] A microcomputer-based low-current grounding fault location device has been further optimized, specifically, as follows: Figure 4 As shown, two elastic support plates 222 are installed on the magnetic mounting plate 202. The two elastic support plates 222 are triangularly distributed, and rubber pads are installed at the connection between the two elastic support plates 222 and the magnetic mounting plate 202. The triangular distribution of the two elastic support plates 222 on the magnetic mounting plate 202 can provide more stable support. When the positioning plate 210 is reset under the action of the reset spring 221 or is subjected to external force, the elastic support plates 222 will undergo elastic deformation, playing a role in buffering and supporting. The rubber pads further enhance the stability and buffering effect of the connection between the elastic support plates 222 and the magnetic mounting plate 202, reducing the transmission of vibration and impact.
[0041] The stability of the structure is enhanced by the triangularly distributed elastic support plates 222. This distribution method makes the supporting force more evenly distributed on the magnetic mounting plate 202, which improves the stability of the entire device during operation and reduces shaking or displacement caused by external forces.
