Description

Technical Field

[0001] This application relates to the field of electrical control technology engineering, specifically to a control box. Background Technology

[0002] Industrial sites typically require two-wire power distribution units. These units must provide power to primary instruments such as piezoelectric accelerometers, while simultaneously acquiring, amplifying, processing, and performing anti-interference measures on the input current signal before outputting isolated current and voltage signals for use by secondary instruments or other instruments, such as data acquisition units. However, some specialized industrial sites require power distribution units that also provide signal isolation, along with spark-proof explosion-proof performance to reliably prevent crosstalk between high-voltage power and signals. These units utilize dual current and voltage limiting circuits to confine energy entering hazardous areas below safety limits—specifically, safety barriers. Safety barriers not only prevent hazardous energy from entering hazardous areas through intrinsically safe terminals, improving the system's intrinsic safety and explosion-proof performance, but also enhance the system's anti-interference capabilities, significantly improving operational reliability. Safety barriers are typically mounted on DIN 35 rails.

[0003] An existing outdoor compressor control cabinet includes a cabinet body, a PLC controller, a circuit breaker, an internal fiber optic transceiver, terminal blocks, an exhaust fan, a frequency converter, a safety barrier, and relays. The core component of the control cabinet is the PLC controller, which includes a data acquisition module, a data communication module, and a control execution module. In existing technology, due to the limited space required for the DIN35 DIN rail mounting base of the safety barrier, the PLC controller and the safety barrier need to be housed in different sections within the control cabinet, resulting in an increased cabinet size to accommodate these functional components.

[0044] The embodiments of the present application will be described in detail below with reference to the drawings.

[0045] Referring to Figure 2-5 As shown in the figure, in some embodiments of the present application, a control box is provided, comprising: a shell 1, a safety fence group 2, a guide rail 5, a data acquisition module 7 and a power supply 10. The inside of the shell 1 has a receiving cavity, and the safety fence group 2, the guide rail 5, the data acquisition module 7 and the power supply 10 are received in the receiving cavity. The safety fence group 2 is composed of a plurality of safety fences, and the safety fences are connected to the guide rail 5 through connectors 21. Among them, the guide rail 5 adopted in the present scheme is a DIN35 guide rail which is matched with the conventional connector 21 of the safety fence. The data acquisition module 7 is provided with a guide rail buckle 71 on one side, and the data acquisition module 7 is slidably connected to the guide rail 5 through the guide rail buckle 71. The safety fence group 2 and the data acquisition module 7 are installed on the same guide rail 5, and the layout of the data acquisition module 7 and the safety fence group 2 is more compact.

[0046] Further, the number of the safety fence groups 2 is two groups, and the two groups of safety fence groups 2 are located on two sides of the data acquisition module 7. The power supply 10 is electrically connected with the data acquisition module 7. Via the power supply 10, the data acquisition module 7 can perform the function of data collection. For example, the safety fence group 2 includes four safety fences, so that four safety fences are arranged on each side of the data acquisition module 7, and 1-8 safety fences can be used as needed. It should be understood that the number of safety fences of the safety fence group 2 includes but is not limited to four, and the number of safety fences of the safety fence group 2 can be two, three, five or more. Meanwhile, the number of safety fence groups 2 on the two sides of the data acquisition module 7 can be consistent or inconsistent, and the number of safety fences in the safety fence group 2 is set according to the actual maximum use requirement.

[0047] In the present scheme, the power supply 10 is arranged above and below the data acquisition module 7, specifically, the power supply 10 is located above the data acquisition module 7, and the power supply 10 and the data acquisition module 7 are arranged in a stacked manner. Since the data acquisition module 7 and the safety fence are installed on the guide rail 5, the height of the safety fence is higher than that of the data acquisition module 7. A recessed space is formed between the two safety fence groups 2 and the top of the data acquisition module 7, and the power supply 10 is arranged in the recessed space to optimize the layout design of the internal structure of the control box, so that the positions of the safety fence group 2, the data acquisition module 7 and the power supply 10 are more compact, thereby reducing the space of the accommodating cavity and further reducing the volume of the shell 1. The shell 1 is made of stainless steel to ensure the explosion-proof performance of the shell 1. Meanwhile, it also leads to the increase of the volume of the shell 1, and the required manufacturing material also increases accordingly, and the cost of stainless steel material with excellent explosion-proof performance is high. By reducing the volume of the shell 1, the manufacturing cost of the entire device can be reduced.

[0048] The accommodating cavity of the shell 1 is also provided with a bottom plate 4. In the present scheme, the shell 1, the bottom plate 4 and the guide rail 5 are connected with each other through connecting pieces, wherein the connecting pieces can be screws (3, 6). The bottom plate 4 is fixedly connected to the shell 1 through the first screw 3. The guide rail 5 is fixedly connected to the bottom plate 4 through the second screw 6.

[0049] More specifically, the control box further includes a power supply support, the power supply support 9 is fixedly connected to the mounting bottom plate 4, and the structure of the power supply support 9 is a top plate and four vertical columns connected with the top plate, and the top plate is erected above the guide rail 5 through the vertical columns. In the present scheme, the vertical columns are fixedly connected to the bottom plate 4, and the vertical columns are connected with the bottom plate 4 through the third screw 8. The power supply 10 is arranged at the top of the power supply support 9, specifically, the power supply 10 is mounted on the top plate. The data acquisition module 7 is located in the power supply support 9, specifically, the four vertical columns are circumferentially distributed on the bottom surface of the top plate, and the data acquisition module 7 is arranged in the space formed by the four vertical columns. The four vertical columns abut against the opposite sides of the data acquisition module 7, and the data acquisition module 7 is limited to slide along the guide rail 5 by the vertical columns.

[0050] Further, the top plate is provided with a avoiding slot. When the data acquisition module 7 is installed in the power support 9, the grounding wire on the data acquisition module 7 extends from the avoiding slot and is connected to the shell 1.

[0051] The shell 1 is provided with a plurality of interfaces for connecting sensors. Since the interfaces are connected to the data acquisition module 7, the data on the sensors can be transmitted to the data acquisition module 7. Generally, the interfaces are connected to the data acquisition module 7 through a wired connection. In order to avoid the transmission line between the interface and the data acquisition module 7 from falling off due to the shaking of the data acquisition module 7, the data acquisition module 7, the power support 9, the bottom plate 4 and the shell 1 form a relatively fixed structure, thereby avoiding the data acquisition module 7 from sliding on the guide rail 5.

[0052] In some embodiments of the present application, the guide rail 5 has an upper flange 51 which is installed in the joint 21. The joint 21 has a recess which matches the upper flange 51, so that the upper flange 51 is embedded in the recess, thereby enabling the safety fence to be stably installed on the guide rail 5.

[0053] Meanwhile, the guide rail buckle 71 has a slot which matches the upper flange 51. The guide rail buckle 71 is fixed on the body of the data acquisition module 7, and the upper flange 51 can be inserted into the slot of the guide rail buckle 71, so that the guide rail buckle 71 is slidingly connected with the guide rail 5.

[0054] In some embodiments of the present application, as shown in Figure 1 The shell 1 includes a box body 11 and a cover body 12 which is pivotally connected to the box body 11 through a hinge 13. A receiving cavity is arranged on the box body 11, and an opening which is in communication with the receiving cavity is formed on a surface of the box body 11. Through the hinge 13, the cover body 12 can be rotated relative to the box body 11, so that the cover body 12 can cover the opening or be away from the opening, so that the receiving cavity appears as a sealed cavity.

[0055] Further, in order to facilitate the grasping of the cover body 12 to drive the cover body 12 to rotate, in the present scheme, a handle 14 is installed on one side surface of the cover body 12. Specifically, the handle 14 is rotationally connected to the upper surface of the cover body 12. The handle 14 can be rotated to a first attitude position or a second attitude position relative to the cover body 12. The handle 14 has a holding reference surface which can be regarded as a plane in which the center line of the handle 14 is located. When the handle 14 is rotated to the first attitude position, the handle 14 is laid on the surface of the cover body 12, and the holding reference surface is parallel to the upper surface of the cover body 12 or the included angle between the holding reference surface and the upper surface of the cover body 12 is approximately 0°. When the handle 14 is rotated to the second attitude position, the holding reference surface is perpendicular to the upper surface of the cover body 12.

[0056] The above examples are used to further illustrate the present application, but do not limit the present application to these specific embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be understood as within the protection scope of the present application.
