Description

Technical Field

[0001] This utility model relates to the technical field of electrical equipment, and in particular to the technical field of multi-functional PLC control cabinets. Background Technology

[0002] A control cabinet is an assembly of switching equipment, measuring instruments, protective devices, and auxiliary equipment in a closed or semi-closed metal cabinet or panel, arranged according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger personnel or surrounding equipment. During normal operation, circuits can be connected or disconnected manually or automatically. In case of faults or abnormal operation, protective devices will disconnect the circuit or trigger an alarm. Measuring instruments can display various operating parameters, allow adjustment of certain electrical parameters, and provide alerts or signals for deviations from normal operating conditions. Control cabinets are commonly used in power generation, distribution, and substations.

[0003] Traditional PLC control cabinets are mainly used for electrical control functions such as remote control of motors and switches. However, with the development of industrial automation and informatization, higher requirements have been placed on the functions of control cabinets, including remote monitoring, reliable and real-time data transmission, integrated manual and automatic control, and the acquisition of more field data. To maintain the internal temperature of the PLC control cabinet within a suitable range, most existing PLC control cabinets are equipped with heat dissipation structures. However, the intelligence level of these internal heat dissipation structures is not high, and their continuous operation leads to high energy consumption and susceptibility to damage. Furthermore, many PLC control cabinets also install monitoring equipment, but to ensure an effective viewing angle, the monitoring equipment is often placed in a high position, making maintenance inconvenient. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems in the prior art and propose a multi-functional PLC control cabinet. The PLC control cabinet is equipped with a temperature control and heat dissipation device that can be automatically turned on at a certain temperature. It is equipped with a monitoring probe, which is fixed by a flip-up support arm for easy maintenance.

[0005] To achieve the above objectives, this utility model proposes a multifunctional PLC control cabinet, including a main cabinet, a PLC controller disposed in the main cabinet, an electrical control panel electrically connected to the PLC controller, a human-machine interface panel electrically connected to the PLC controller, and a temperature control and heat dissipation device disposed in the main cabinet. The temperature control and heat dissipation device includes a cooling fan disposed on the side wall of the main cabinet and connected to the outside, a plurality of ventilation openings disposed on the side wall of the main cabinet, and a temperature control sensor disposed in the main cabinet and controlled and connected to the cooling fan.

[0006] The main cabinet is also equipped with a monitoring probe, which is connected to the main cabinet via a support arm. The support arm is hinged to the outer wall of the main cabinet via a hinge shaft. The main cabinet is equipped with a return spring for keeping the support arm in a vertical position.

[0007] Preferably, the main cabinet is also equipped with a dual power switching system, which includes a dual power switching switch and a UPS power supply.

[0008] Preferably, the main cabinet is also equipped with a dual-chain network system for connecting the PLC controller to the network.

[0009] Preferably, the main cabinet is also equipped with a multi-functional electricity meter, which is used to monitor electricity data and upload the data to the PLC controller.

[0010] Preferably, the side wall of the main cabinet is also provided with a limiting block for engaging with the support arm, and the support arm is in a vertical state when engaging with the limiting block.

[0011] Preferably, the side wall of the main cabinet is also provided with a magnetic block for magnetically engaging with the support arm. The support arm has magnetic force or a second magnetic block is provided on the support arm for engaging with the magnetic block. When the support arm engages with the magnetic block, the support arm is in an inclined or lateral state, and the attraction between the magnetic block and the support arm is greater than the elastic force of the return spring.

[0012] The beneficial effects of this multifunctional PLC control cabinet are as follows: This utility model satisfies the control requirements of the cabinet by installing a PLC controller, electrical control panel, and human-machine interface panel inside the main cabinet. It achieves automatic heat dissipation by incorporating a temperature-controlled heat dissipation device inside the main cabinet. When the temperature sensor detects that the internal temperature of the main cabinet is too high, it immediately controls the cooling fan to turn on. The cooling fan, in conjunction with the ventilation vents on both sides, introduces cool outside air into the main cabinet and exhausts hot air from inside, achieving automatic and intelligent heat dissipation. A monitoring probe is installed to facilitate monitoring of the surrounding environment of the main cabinet. The monitoring probe is fixed to the main cabinet by a support arm 8, a hinge shaft, and a return spring. In normal operation, the support arm remains vertically upward to keep the monitoring probe above the main cabinet for optimal monitoring angle. When maintenance of the monitoring probe is required, the support arm can be directly controlled to rotate around the hinge shaft, allowing the monitoring probe to be rotated to a lower position for easy maintenance by the operator.

[0013] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0020] In the description of this utility model, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0021] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0023] See Figure 1 , Figure 2 This utility model discloses a multifunctional PLC control cabinet, including a main cabinet 1, a PLC controller 2 housed within the main cabinet 1, an electrical control panel 3 electrically connected to the PLC controller 2, a human-machine interface panel 4 electrically connected to the PLC controller 2, and a temperature control and heat dissipation device housed within the main cabinet 1. The temperature control and heat dissipation device includes a cooling fan 5 located on the top wall of the main cabinet 1 and connected to the outside, ventilation openings 11 located on the side walls of the main cabinet 1, and a temperature sensor 6 located within the main cabinet 1 and controlled by the cooling fan 5. In this embodiment, the PLC controller 2, electrical control panel 3, and human-machine interface panel 4 are installed within the main cabinet 1 to meet the control requirements of the control cabinet. By installing the temperature control and heat dissipation device within the main cabinet 1, automatic heat dissipation is achieved. When the temperature sensor 6 detects that the internal temperature of the main cabinet 1 is too high, it can immediately control the cooling fan 5 to turn on. The cooling fan 5, in conjunction with the ventilation openings 11 on both sides, introduces cool outside air into the main cabinet 1 and exhausts hot air from inside the main cabinet 1, achieving automatic heat dissipation and making heat dissipation more intelligent.

[0024] See Figure 3 , Figure 4 The main cabinet 1 is also equipped with a monitoring probe 7, which is connected to the main cabinet 1 via a support arm 8. The support arm 8 is hinged to the outer wall of the main cabinet 1 via a hinge shaft 81. The main cabinet 1 is equipped with a return spring 82 to keep the support arm 8 in a vertical position. By setting up the monitoring probe 7, real-time monitoring of the vicinity of the main cabinet 1 can be achieved, facilitating later traceability. In this embodiment, the monitoring probe 7 is fixed to the main cabinet 1 via the support arm 8, hinge shaft 81, and return spring 82. Under normal conditions, the support arm 8 is kept vertically upward so that the monitoring probe 7 is kept above the main cabinet 1 to obtain the best monitoring angle. When maintenance of the monitoring probe 7 is required, the support arm 8 is directly controlled to rotate around the hinge shaft 81 so that the monitoring probe 7 can be rotated to a lower position, making it convenient for operators to directly maintain the monitoring probe 7. After maintenance is completed, the support arm 8 is released, and the support arm 8 can return to a vertical position under the action of the return spring 82, and the monitoring probe 7 returns to above the main cabinet 1 to obtain the best monitoring angle.

[0025] See Figure 2 The main cabinet 1 is also equipped with a dual power switching system, which includes a dual power transfer switch and a UPS power supply. When the external power supply is interrupted, it automatically switches to the backup power supply to ensure the safe operation of the equipment.

[0026] See Figure 2 The main cabinet 1 is also equipped with a dual-link network system 10 for the PLC controller 2 to access the network. A wireless router is added to the wired network; when the wired network unexpectedly drops, the PLC automatically switches to the wireless network to ensure normal data upload and safe operation of the field equipment.

[0027] See Figure 2 The main cabinet 1 is also equipped with a multi-functional electricity meter 12, which is used to monitor electricity consumption data and upload the data to the PLC controller 2. Real-time uploading of electricity consumption data allows for timely analysis of whether on-site energy consumption is normal through the PLC and reports, indirectly reflecting whether the equipment is functioning properly. Example 2:

[0028] See Figure 3 , Figure 4 Based on Embodiment 1, the side wall of the main cabinet 1 is further provided with a limiting block 83 for engaging with the support arm 8. When the support arm 8 engages with the limiting block 83, the support arm 8 is in a vertical position. This serves to limit and position the support arm 8 so that it remains vertical in normal operation, allowing the monitoring probe 7 to obtain the optimal monitoring angle.

[0029] See Figure 3 , Figure 4 The main cabinet 1 is also provided with a magnetic block 9 on its side wall for magnetically engaging with the support arm 8. The support arm 8 has magnetic force or a second magnetic block on the support arm 8 for engaging with the magnetic block 9. When the support arm 8 engages with the magnetic block 9, the support arm 8 is in an inclined or lateral state, and the attraction between the magnetic block 9 and the support arm 8 is greater than the elastic force of the return spring 82. When the support arm 8 is flipped, it can be flipped to the position of the magnetic block 9. The engagement between the magnetic block 9 and the support arm 8 keeps the support arm 8 in position, making it convenient for staff to maintain the monitoring probe 7. After maintenance, releasing the magnetic engagement between the support arm 8 and the magnetic block 9 will allow the support arm 8 to automatically return to its original position.

[0030] The working process of this utility model:

[0031] In the operation of this utility model, a multifunctional PLC control cabinet, the PLC controller 2, the electrical control panel 3, and the human-machine interface panel 4 meet the control requirements of the control cabinet. When the temperature control sensor 6 detects that the internal temperature of the main cabinet 1 is too high, it can immediately control the cooling fan 5 to turn on. The cooling fan 5 works in conjunction with the ventilation openings 11 on both sides to introduce cold air from the outside into the main cabinet 1 and exhaust the hot air inside the main cabinet 1.
