Description

Technical Field

[0001] The utility model belongs to the technical field of automatic PLC control cabinets, in particular to an industrial automatic PLC control cabinet. Background Art

[0002] Industrial automation PLC control cabinet is an important part of modern industrial automation. It integrates programmable logic controllers and related modules to achieve automated control of industrial equipment.

[0003] Industrial automation PLC control cabinets generally consist of a cabinet body and several electrical components. The electrical components are installed in the cabinet body, and the components and the cabinet body are connected together by various wires, including power cables, signal cables, and other connecting cables. To maintain the neatness and appearance of the PLC control cabinet and reduce safety hazards, workers often use cable ties to bundle different types of connecting cables to classify the connecting cables of different components. The tied cables are usually stuffed between two toothed plates for storage. When the PLC controller fails and the staff needs to repair the components, they need to pull out the connecting cables of the relevant components one by one to check and identify the problematic component before repairing it.

[0004] Pulling out cables and untying cable ties makes the troubleshooting process tedious and cumbersome, hindering smooth repair work. Furthermore, since the power cord generates heat when current flows through it, being stored between the two toothed plates can affect the power cord's heat dissipation and easily cause other cables to overheat, accelerating cable aging, reducing cable life, and potentially creating safety hazards such as short circuits.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an industrial automation PLC control cabinet. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] like Figures 1 to 5 As shown, an industrial automation PLC control cabinet in one embodiment of the present invention includes a control cabinet body 1, mounted with a first cooling fan 211 to dissipate heat generated within the control cabinet body 1. A cable assembly 2 is mounted on one side of the control cabinet body 1. The cable assembly 2 includes a cable take-up component and a heat dissipation component that mates with the first cooling fan 211. The heat dissipation component is located outside the control cabinet body 1. The heat dissipation component blows air toward the phase change material, connecting wires, and power cords, removing heat absorbed from the power cords by the phase change material. This allows the phase change material to continue absorbing heat from the power cords, thereby cooling the power cords and, to a certain extent, slowing down the aging of the power cords. The cable take-up component is located within the control cabinet body 1. It groups the connecting wires and power cords of components within the control cabinet body 1. When troubleshooting, the power cords and all other connecting wires can be exposed, allowing quick access to the connecting wires connected to different components and facilitating troubleshooting.

[0029] like Figure 3As shown, the wire take-up component includes a first limiting plate 201, which is fixedly connected to the control cabinet body 1. A connecting assembly matching the second limiting plate 204 is installed below the first limiting plate 201. The second limiting plate 204 is detachable, and a storage space for wire take-up is provided between the first limiting plate 201 and the second limiting plate 204. Since the second limiting plate 204 is detachable from the first limiting plate 201, when the staff needs to check the connection wires, they can separate the second limiting plate 204 from the first limiting plate 201, thereby simultaneously exposing all the connection wires between the first limiting plate 201 and the second limiting plate 204. Compared with pulling out the connection wires between the first limiting plate 201 and the second limiting plate 204 one by one, it is more convenient for quick inspection.

[0030] like Figure 3 As shown, the connecting assembly includes a connecting rod 205, which is fixedly connected to the second limiting plate 204. A clamping block 206 is fixedly connected to the end of the connecting rod 205 close to the first limiting plate 201. The first limiting plate 201 is provided with a slot 203 and a connecting slot 202 that match the clamping block 206. The clamping block 206 is aligned with the connecting slot 202 and pushed upward until the clamping block 206 is located at the upper part of the first limiting plate 201. The clamping block 206 and the second limiting plate 204 are moved toward the slot 203. The clamping block 206 and the second limiting plate 204 are moved downward until the clamping block 206 engages with the slot 203, thereby fixing the second limiting plate 204. The connecting line between the second limiting plate 204 and the first limiting plate 201 can be stored and fixed.

[0031] like Figures 3 and 4 As shown, a second U-shaped stopper 216 and a plurality of first U-shaped stoppers 207 are installed on the side of the first stopper plate 201 and the second stopper plate 204 near the storage space. The second U-shaped stopper 216 and the first U-shaped stopper 207 separate and categorize the connecting wires of different components, making it easier for staff to find connecting wires of different distances and facilitate troubleshooting.

[0032] Specifically, the distance between the first limiting plate 201 and the second limiting plate 204 can accommodate 1 to 1.5 first U-shaped limiting members 207, so that the first limiting plate 201 and the second limiting plate 204 do not affect the placement of the components. The first U-shaped limiting member 207 can accommodate the connecting wire of an element without causing friction between the connecting wires.

[0033] like Figure 4 As shown, the first U-shaped limiter 207 and the second U-shaped limiter 216 are fixedly connected to the first limiter block 208 and the second limiter block 209 on one side close to the storage space, and a wire inlet is formed between the first limiter block 208 and the second limiter block 209.

[0034] Specifically, the first limit block 208 and the second limit block 209 are both inclined toward the inside of the first U-shaped limit piece 207 and the second U-shaped limit piece 216, and the length of the second limit block 209 is greater than the first limit block 208, so that the wire inlet between the first limit block 208 and the second limit block 209 can impose certain constraints on the connecting wires and the power cord, and avoid as much as possible that when the staff restricts the connecting wires and the power cord in the storage space, the connecting wires and the power cord themselves are bent, causing the connecting wires and the power cord to be squeezed out of the wire inlet, resulting in mixing between the connecting wires and the power cord, affecting the staff's arrangement of the connecting wires and the power cord.

[0035] like Figures 1 and 2 As shown, the heat dissipation component includes a wind collecting cover 212, which matches the first heat dissipation fan 211. An exhaust pipe 213 is fixedly connected to the bottom of the wind collecting cover 212. A second heat dissipation fan 214 matching the exhaust pipe 213 is installed below the exhaust pipe 213. The second heat dissipation fan 214 is rotatably connected to the control cabinet body 1. The control cabinet body 1 is provided with a plurality of heat dissipation ports 215 matching the heat dissipation component. When the first heat dissipation fan 211 discharges the hot air in the control cabinet body 1, the hot air blows the second heat dissipation fan 214 through the exhaust pipe 213. The wind generated during the rotation of the second heat dissipation fan 214 dissipates heat and cools the phase change material through the heat dissipation ports 215, thereby reducing the temperature of the power cord in the second U-shaped limiter 216, thereby avoiding poor heat dissipation of the power cord, excessive temperature, and aging of the power cord.

[0036] At the same time, since the exhaust pipe 213 is inclined toward the side away from the control cabinet body 1 , the hot air discharged from the exhaust pipe 213 is prevented from flowing toward the control cabinet body 1 to a certain extent, causing the temperature of the outer wall of the control cabinet body 1 to rise.

[0037] like Figure 4 As shown, the outer wall of the second U-shaped retainer 216 is mounted with the housing 210, and the phase change material is placed inside the housing 210. The phase change material disposed on the outer wall of the second U-shaped retainer 216 absorbs heat during the phase change process, thereby achieving a better cooling effect of the second U-shaped retainer 216, allowing staff to classify and store wires according to the heat dissipation requirements of different connecting wires and power cords.

[0038] Specifically, the phase change material used to improve the heat dissipation effect can be paraffin or fatty acid, etc., and the staff can make the selection based on the actual situation.

[0039] like Figure 5As shown, a positioning assembly 3 is installed on the wiring assembly 2. When the staff refers to the drawings to install the components, the positioning assembly 3 can assist the staff in determining the component position, which improves the accuracy and neatness of the installation position to a certain extent. The positioning assembly 3 includes a scale line 301 and a positioning assembly for assisting in the installation of the component. The positioning assembly includes a T-shaped slide 303. The T-shaped slide 303 is opened at the bottom of the second limit plate 204. A T-shaped slider 304 is slidably connected in the T-shaped slide 303. A positioning block 305 is installed on the T-shaped slider 304, and a positioning bolt 306 is threadedly connected to the positioning block 305. After moving the positioning block 305 to the appropriate position, the positioning bolt 306 is rotated so that the positioning bolt 306 is against the inner wall of the scale line 301, thereby fixing the positioning block 305. One side of the component is aligned with the positioning block 305, and the component is then fixed with the bolts. That is, the positioning assembly 3 assists in completing the installation of the component. Through the measurement of 302 and the positioning of the positioning block 305, the component position is made more accurate.

[0040] During use, the connecting wires and power cords connected to the components are pushed toward the line inlet according to different heat dissipation requirements, and the connecting wires and power cords are received in the first U-shaped limiting member 207. The connecting wires are then classified and fixed by the second limiting plate 204 through the card slot 203 and the card block 206, thereby completing the storage of the connecting wires and power cords. When it is necessary to check the component connecting wires and power cords, the second limiting plate 204 is moved downward with the cooperation of the connecting slot 202, so that all the connecting wires and power cords can be exposed at the same time. The staff can take out the connecting wires through the line inlet for inspection. There is no need to pull out the connecting wires or untie the cable ties, making the inspection process more convenient and rapid, which is conducive to the smooth progress of maintenance work. The heat dissipation mechanism can also cool the connecting wires and power cords, avoiding poor heat dissipation of the power cord in the storage space, resulting in excessive temperature of the power cord, and ultimately leading to safety hazards such as aging of the power cord insulation layer and short circuit.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0042] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
