Description

Technical Field

[0001] This utility model relates to the technical field of current monitoring devices, and more specifically, to a current monitoring device for automated warehouses. Background Technology

[0002] In power systems, accurate current monitoring is a crucial step in ensuring stable and safe power supply. This is especially important in automated storage and retrieval systems, where power lines are complex and dense. Real-time current monitoring helps to detect potential faults in a timely manner and prevent problems such as short circuits and overloads. Closed-loop current sensors, as high-precision and high-stability current detection elements, are widely used in various power monitoring systems. These sensors measure the current by passing the current line to be measured through its central hole and using the principle of electromagnetic induction. They have advantages such as accurate measurement and fast response speed.

[0003] However, in practical applications, especially in special environments like automated warehouses, traditional closed-loop current sensors face a critical problem: the wires lack stable support when passing through the sensor, making them prone to deviating from the sensor's center position due to factors such as gravity, vibration, or human operation, which affects the accuracy of current measurement. Therefore, we have made improvements to address this issue and proposed a current monitoring device for automated warehouses. Utility Model Content

[0027] As described in the background section, in practical applications, especially in special environments such as automated warehouses, traditional closed-loop current sensors face a key problem: the wires lack stable support when passing through the sensor and are easily deviated from the center position of the sensor due to factors such as gravity, vibration, or human operation, which affects the accuracy of current measurement.

[0028] To solve this technical problem, this utility model provides a current monitoring device for automated warehouses.

[0029] For details, please refer to Figures 1-4 The current monitoring device for automated warehouses specifically includes:

[0030] The current sensor body 1 has a support and fixing structure 2 on both sides. The support and fixing structure 2 includes a support member on the current sensor body 1, a support tube 206 connected to the support member, a second hand-tightening bolt 207 threadedly connected to the support tube 206, and one end of the second hand-tightening bolt 207 extending into the support tube 206 and connected to a clamping plate 208 through a bearing.

[0031] The current monitoring device for automated warehouses provided by this utility model adds support and fixing structures 2 on both sides of the current sensor body 1. The support and fixing structures 2 can effectively support and fix the wire, ensuring that the wire is always located in the central area of ​​the current sensor body 1, thereby reducing the measurement error caused by the wire position deviation and improving the accuracy and reliability of current monitoring.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Example 1, please refer to Figures 1-4 A current monitoring device for automated warehouses includes a current sensor body 1. Supporting and fixing structures 2 are provided on both sides of the current sensor body 1. Each supporting and fixing structure 2 includes a support member mounted on the current sensor body 1. A support tube 206 is connected to the support member, and a second hand-tightening bolt 207 is threaded onto the support tube 206. One end of the second hand-tightening bolt 207 extends into the support tube 206 and is connected to a clamping plate 208 via a bearing. This application, by adding supporting and fixing structures 2 on both sides of the current sensor body 1, effectively supports and fixes the wire, ensuring that the wire is always located in the central area of ​​the current sensor body 1. This reduces measurement errors caused by wire position deviation and improves the accuracy and reliability of current monitoring. Specifically, the wire passes through the support tube 206, and the second hand-tightening bolt 207 and the clamping plate 208 cooperate to clamp and fix the wire, thus achieving support of the wire by the supporting and fixing structure 2.

[0036] Furthermore, such as Figure 4 As shown, the support includes a connecting seat 201 mounted on the current sensor body 1. A groove 202 is provided on the side of the connecting seat 201 away from the current sensor body 1. A support plate 203 is inserted into the inner wall of the groove 202. The support plate 203 is connected to the support tube 206 and can support the support tube 206.

[0037] Example 2 further optimizes the current monitoring device for automated warehouses provided in Example 1. Specifically, a fixing member is provided between the support plate 203 and the connecting seat 201. The fixing member is used to fix the position of the support plate 203.

[0038] Furthermore, such as Figures 1-4 As shown, the fastener includes an elongated opening 204 on the support plate 203 and a first hand-tightening bolt 205 threaded onto the connecting seat 201. The first hand-tightening bolt 205 passes through the inner wall of the elongated opening 204. After loosening the first hand-tightening bolt 205, the support plate 203 can be moved up and down, thereby adjusting the position of the support tube 206 so that the wire can correspond to the center of the hole in the middle of the current sensor body 1. When the first hand-tightening bolt 205 is tightened, the position of the support plate 203 can be fixed, thereby fixing the support tube 206.

[0039] Furthermore, such as Figure 3 As shown, mounting slots 101 are provided on both sides of the current sensor body 1.

[0040] Example 3 further optimizes the current monitoring device for automated warehouses provided in Example 1 or 2, specifically, as follows: Figures 1-3 As shown, a mounting structure 3 is provided between the current sensor body 1 and the two mounting slots 101. The mounting structure 3 cooperates with the mounting slots 101 to fix the current sensor body 1.

[0041] Furthermore, such as Figure 3 As shown, the mounting structure 3 includes a mounting base 301 located below the current sensor body 1. A limiting groove 302 is formed on the top of the mounting base 301, and the inner wall of the limiting groove 302 is inserted into the bottom of the current sensor body 1. The insertion of the limiting groove 302 into the current sensor body 1 can position the current sensor body 1 when it is connected to the mounting base 301.

[0042] Furthermore, such as Figures 1-3 As shown, a sliding groove 303 is provided on the mounting base 301. A bidirectional lead screw 304 is connected to the sliding groove 303 through a bearing. Two limiting rods 305 are threadedly connected to the outer surface of the bidirectional lead screw 304. The two limiting rods 305 are respectively inserted into the inner walls of the two mounting grooves 101. By rotating the bidirectional lead screw 304, the two limiting rods 305 can be driven to move closer or further away from each other. When the two limiting rods 305 move closer to each other, they can be inserted into the mounting grooves 101 to fix the current sensor body 1. When the two limiting rods 305 move further away from each other, they can be separated from the mounting grooves 101, thereby releasing the fixation of the current sensor body 1.

[0043] Furthermore, such as Figures 1-3 As shown, the tops of the two limiting rods 305 are fixedly connected to limiting plates 306, and the bottom of the limiting plates 306 is in contact with the current sensor body 1. The limiting plates 306 can limit the current sensor body 1 to improve the stability of the current sensor body 1 when it is fixed by the mounting structure 3.

[0044] Furthermore, such as Figures 1-3 As shown, the mounting base 301 has several mounting holes 307. The mounting holes 307 are used for auxiliary fixing of the mounting base 301. The mounting base 301 can be fixed to the corresponding support object by passing bolts through the mounting holes 307.

[0045] The usage process of the current monitoring device for automated warehouses provided by this utility model is as follows:

[0046] The mounting base 301 can be fixed to the corresponding support object by passing the bolt through the mounting hole 307. Loosen the second hand-tightening bolt 207, and pass the wire between the support tube 206 and the current sensor body 1. First, tighten one of the second hand-tightening bolts 207 to fix the wire. Then, pull the wire to straighten it and tighten the other second hand-tightening bolt 207. After loosening the first hand-tightening bolt 205, adjust the position of the support plate 203 and the support tube 206 so that the wire is aligned with the center of the current sensor body 1. Then tighten the first hand-tightening bolt 205. The current of the wire is monitored by the current sensor body 1.
