Description
Technical Field
[0001] This utility model relates to the field of electrical equipment technology, and in particular to an automatic frequency conversion electrical control cabinet applicable to multiple locations. Background Technology
[0002] Electrical control cabinets ensure the coordinated operation of various electrical subsystems, providing solid support for the normal operation of business activities. In the field of transportation, whether it is the train operation control of urban rail transit or the operation of cargo loading and unloading equipment in ports and airports, electrical control cabinets bear the important responsibility of power distribution and equipment control.
[0003] For example, CN215452093U discloses an intelligent dehumidification and moisture-proof electrical control cabinet for electrical automation engineering, including a cabinet, a top plate fixedly connected to the upper end of the top of the inner cavity of the cabinet, a number of openings in the middle of the top plate, a first filter element fixedly connected to the top of the top plate, ventilation holes opened at the upper ends of the left and right sides of the cabinet, a filter box fixedly connected to the bottom of the cabinet, and a second filter element inserted into the inner cavity of the filter box;
[0004] Although the patented control cabinet is equipped with a sealing plate, vents, air inlets, and a second filter, and can dry the air inside the cabinet through fan circulation, thus solving the dehumidification and moisture prevention problem to a certain extent and minimizing the damage to internal electronic components due to moisture, its heat dissipation method relies solely on natural ventilation and a cooling fan. This results in limited heat dissipation capacity in high-temperature environments and cannot meet the heat dissipation needs of complex environments in multiple locations. Furthermore, the internal wiring structure lacks optimized design, potentially leading to chaotic wiring management. Additionally, the overall structure is relatively fixed, resulting in insufficient adaptability to different locations. Therefore, we are introducing an automatic frequency conversion electrical control cabinet suitable for multiple locations. Utility Model Content
[0005] The main purpose of this utility model is to provide an automatic frequency conversion electrical control cabinet applicable to multiple locations, which can effectively solve the problems in the background technology.

[0027] Please see Figure 1-4 This utility model provides a technical solution:
[0028] An automatic frequency conversion electrical control cabinet applicable to multiple locations includes an upper cover plate 1, a support device 8 fixedly connected to the lower end of the upper cover plate 1, a cabinet door 2 installed at the front end of the support device 8 via a hinge, a transparent cover 3 provided at the front end of the cabinet door 2, a side plate 5 fixedly connected to the lower right end of the support device 8, a connecting device 6 fixedly installed at the upper end of the side plate 5, two cable routing devices 7 slidably installed on the inner cabinet wall of the support device 8, and support feet 4 fixedly connected to the four corners of the lower end of the support device 8.
[0029] In this embodiment, the connecting device 6 includes a blower device 62. The input end of the blower device 62 is connected to an air supply pipe 63, and the other end of the air supply pipe 63 is fixedly connected to an air chamber 61. An installation groove 64 is opened at the upper end of the air chamber 61. Several air outlet pipes 65 are fixedly installed on the surface of the air chamber 61. Several electric heating tubes 66 are fixedly installed on the upper part of the front and rear walls of the installation groove 64. The bottom of the blower device 62 is fixedly installed on the upper end of the side plate 5. The supporting device 8 includes a cabinet 81. A filter ventilation screen 83 is provided at the left, right, and upper ends of the cabinet 81. A temperature sensor 87 is provided at the lower part of the rear wall of the cabinet 81. A groove 84 is opened in the lower wall of the cabinet 81. The inner surface of the groove 84... The upper part of the groove wall is provided with several grid strips 85. The lower right end of the cabinet body 81 has a pipe hole 86. The left and right cabinet walls of the cabinet body 81 are each provided with two sliding grooves 82. The cabinet body 81 is installed at the rear end of the cabinet door 2 by a hinge. Several electric heating tubes 66 are distributed horizontally at equal intervals and do not contact the several grid strips 85. Several air outlet pipes 65 are connected to the inside of the air blower box 61 and are distributed in a long rectangle at equal intervals. The air blower box 61 is fixedly installed in the groove 84. The filter ventilation mesh 83 is embedded in the ventilation openings at the left, right and upper ends of the cabinet body 81, and the mesh count of the filter ventilation mesh 83 is 120 mesh. The sensing end of the temperature sensor 87 is set facing the inside of the cabinet body 81 and is connected to the external display device through a data cable.
[0030] Through the above scheme: the temperature sensor 87 at the lower part of the rear wall of the cabinet 81 monitors the temperature and humidity inside the cabinet in real time. When the temperature is too high or the humidity is too high, the blower 62 installed on the upper part of the side panel 5 is started, and air is delivered to the air box 61 fixed in the groove 84 of the lower wall of the cabinet 81 through the air pipe 63. The air outlet pipe 65, which is a long rectangular shape with equal spacing on the surface of the air box 61 and communicates with the interior, disperses and discharges the gas, ventilating and dissipating heat inside the cabinet 81. At the same time, the electric heating tubes 66, which are horizontally evenly distributed in the mounting groove 64 of the air box 61, heat the air, and the heated air enters the cabinet 81. To reduce humidity and prevent the electric heating element 66 from contacting the grille strip 85, thus avoiding impact on other components, the 120-mesh filter ventilation screen 83 embedded at the left, right, and top ends of the cabinet 81 can filter external dust and other impurities during ventilation, ensuring clean air entering the cabinet. In addition, the sliding groove 82, recess 84, and pipe hole 86 of the cabinet 81, together with the wiring device 7, cabinet door 2, and support feet 4, achieve orderly wiring, convenient operation of equipment, and stable placement. The cooperation between the connecting device 6 and the bearing device 8 realizes the intelligent heat dissipation and dehumidification function of the automatic frequency conversion electrical control cabinet, effectively coping with environmental changes in multiple locations.
[0031] In this embodiment, the cable routing device 7 includes a cable routing frame 71. Slide bars 72 are fixedly connected to both the left and right ends of the cable routing frame 71. A back plate 73 is fixedly connected between the rear part of the left frame wall and the rear part of the right frame wall of the cable routing frame 71. Several mounting holes 74 are opened at the front end of the back plate 73. Several wire-passing grooves 75 are opened at both the upper and lower ends of the cable routing frame 71. The cable routing frame 71 is slidably installed in the cabinet 81 through the slide bars 72. The cable routing frame 71 has an I-shaped structure. The cross-section of the slide bars 72 has an I-shaped structure. The mounting holes 74 are distributed in a matrix at the front end of the back plate 73, and the distance between two adjacent mounting holes 74 is 30mm. The inner wall of the mounting holes 74 is provided with internal threads.
[0032] Through the above scheme: the cable tray 71 can slide flexibly within the grooves 82 on the left and right walls of the cabinet 81 via I-shaped sliding strips 72 at both ends. This allows for free adjustment of the cable tray 71's position within the cabinet 81 according to different wiring requirements and component installation locations within the electrical control cabinet. The front end of the rear plate 73 features matrix-distributed mounting holes 74 spaced 30mm apart and with internal threads, providing standardized interfaces for the installation of various electrical components. Components can be securely mounted on the cable tray 71 using matching bolts and other connectors. Several wire channels 75 at the top and bottom of the cable tray 71 provide dedicated pathways for wires, facilitating wiring. When wiring, wires can be passed through the cable tray 75 in sequence, allowing them to be arranged in an orderly manner along a preset path, avoiding tangling and mess. The sliding installation design of the cable tray 71 and the cabinet 81 greatly improves the flexibility and adaptability of wiring, meeting the different wiring needs of various locations. The standardized design of the mounting holes 74 facilitates the quick installation and removal of electrical components, improving installation efficiency and making it easier to replace and maintain components later. The cable tray 75 ensures that the wires are neatly and systematically arranged, making the internal wiring layout of the control cabinet clearer and allowing staff to intuitively understand the wiring connections. It also effectively reduces the risk of short circuits and other faults caused by tangled wires.
[0033] It should be noted that this utility model is an automatic frequency conversion electrical control cabinet applicable to multiple locations. A temperature sensor 87 located at the lower rear wall of the cabinet 81 monitors the internal temperature in real time. Its sensing end faces inwards from the cabinet 81. Monitoring data is transmitted to an external display device via a data cable. When high internal temperature or humidity is detected, the connecting device 6 starts working, and the blower 62 is activated. Air is delivered to the air chamber 61 through the air supply pipe 63. Several air outlet pipes 65, arranged in a long rectangular shape and equidistantly on the surface of the air chamber 61, disperse and discharge the gas, providing ventilation and heat dissipation for the cabinet 81. Simultaneously, several horizontally equidistant electric heating tubes 66 in the mounting slot 64 heat the air. The heated air enters the cabinet 81, effectively reducing internal humidity. Since the electric heating tubes 66 do not contact the grille strips 85, damage to other components inside the cabinet 81 during heating is avoided. The filter ventilation screens 83, with a mesh size of 120, are installed on the left, right, and top ends of the cabinet 81. They can filter external dust and other impurities during ventilation, ensuring that the air entering the cabinet is clean. The slide rails 72, with an I-shaped cross-section at both ends, are slidably installed in the slide grooves 82 on the left and right sides of the cabinet 81. Their positions can be adjusted according to actual needs. The front end of the rear panel 73 has several mounting holes 74 arranged in a matrix, spaced 30mm apart, and with internal threads on the inner wall, which facilitates the installation and fixing of electrical components. The several wire grooves 75 at the top and bottom of the cable tray 71 provide an orderly passage for the wires, making the wires neatly arranged and easy to manage and maintain. The transparent cover 3 at the front end of the cabinet door 2 allows the operator to observe the operation of the equipment inside the cabinet. The cabinet door 2 is connected to the cabinet 81 by hinges, making it easy to open and close. The support feet 4 at the four corners of the lower end of the load-bearing device 8 ensure the stable placement of the control cabinet.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
