Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a PLC electrical control cabinet with an adjustable base support structure. This solves the problem that PLC electrical control cabinets are often installed in factories, workshops, outdoors, or on ships, where the ground may be uneven. The base supports of the aforementioned technologies are not adjustable, which can easily cause the equipment to tilt and affect continuous and stable operation. Furthermore, PLC electrical control cabinets generate a lot of heat during operation. The aforementioned technologies use air intakes on the sides and top of the control cabinet for heat dissipation, but the air travels a short distance inside the control cabinet and cannot remove a significant amount of heat.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a PLC electrical control cabinet with a bottom support adjustment structure, comprising:
[0007] The control cabinet body has a sealing cover hinged to the front, ventilation slots on both sides of the top of the control cabinet body, and a protective cover fixedly connected to the bottom of the control cabinet body.
[0008] An adjustment component, the top of which is fixedly connected to the bottom of the control cabinet body, is used to adjust the height of the PLC electrical control cabinet;
[0009] A ventilation assembly is provided, one side of which is fixedly connected to the bottom of the inner wall of the control cabinet body. The ventilation assembly is used to exchange the air generated by the operation of the PLC electrical control cabinet with the low-temperature air outside.
[0010] Preferably, the adjustment assembly includes a threaded sleeve that is threaded to the bottom of the control cabinet body, and a screw rod is threadedly connected to the inner wall of the threaded sleeve.
[0011] Preferably, a conical stabilizing sleeve is fixedly connected to the surface of the screw rod, an operating handle is fixedly connected to the surface of the conical stabilizing sleeve, and a support base is fixedly connected to the bottom end of the screw rod.
[0012] Preferably, the ventilation assembly includes a mounting sleeve fixedly connected to the bottom of the inner wall of the control cabinet body, and an air outlet branch pipe fixedly connected to the inner wall of the mounting sleeve, with one end of the air outlet branch pipe connected to an air outlet pipe.
[0013] Preferably, a fan is fixedly connected to the bottom of the control cabinet body, the air outlet of the fan is connected to the bottom end of the air outlet pipe, and a limit plate is slidably connected to the bottom of the control cabinet body through a dovetail groove.
[0014] Preferably, the air inlet of the fan is connected to an air inlet branch pipe through the main air inlet pipe, an isolation ring is fixedly connected to the inner wall of the air inlet branch pipe, a filter element column is movably connected to one side of the isolation ring, and a disc is fixedly connected to one end of the filter element column.
[0015] This utility model provides a PLC electrical control cabinet with a bottom support adjustment structure. Compared with the prior art, it has the following advantages:
[0016] 1. This PLC electrical control cabinet with a base support adjustment structure utilizes the adjustment components to place the support base on the ground. Depending on the horizontal position, the screw rod on the inner wall of the threaded sleeve is rotated. The conical stabilizing sleeve and screw rod are rotated by hand using the operating handle. The screw rod moves downwards along the threaded sleeve, simultaneously causing the conical stabilizing sleeve and support base to move downwards. The conical stabilizing sleeve surrounds the outer circumference of the support base, improving the stability of the PLC electrical control cabinet after placement. Four symmetrical adjustment components are located at the bottom of the control cabinet body, allowing for convenient height adjustment at each corner, keeping the internal equipment of the PLC electrical control cabinet level and ensuring continuous stable operation.
[0017] 2. This PLC electrical control cabinet with a bottom support adjustment structure utilizes the ventilation components. Through the air intake pipe at the bottom, the PLC electrical control cabinet can draw low-temperature air from the bottom of the control cabinet body. According to the principle of thermodynamics, hot air, which is lighter, naturally rises. The low-temperature air at the bottom gradually heats up after passing through the working equipment and finally flows to the ventilation slots on both sides of the top of the control cabinet body. The air travel is relatively long, which can comprehensively remove the heat generated by the equipment in the control cabinet body. In addition, the filter column can filter the air. Replacement and maintenance can be completed by simply pulling the limit plate to pull out the filter column, which is convenient and quick. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-4 This utility model provides two technical solutions:
[0026] Example 1: A PLC electrical control cabinet with a bottom support adjustment structure, comprising:
[0027] The control cabinet body 1 has a sealing cover 2 hinged to the front of the control cabinet body 1, ventilation slots 3 are provided on both sides of the top of the control cabinet body 1, and a protective cover 6 is fixedly connected to the bottom of the control cabinet body 1.
[0028] Adjustment component 4, the top of adjustment component 4 is fixedly connected to the bottom of control cabinet body 1, and adjustment component 4 is used to adjust the height of PLC electrical control cabinet;
[0029] The ventilation assembly 5 is fixedly connected to the bottom of the inner wall of the control cabinet body 1 on one side. The ventilation assembly 5 is used to exchange the air generated by the operation of the PLC electrical control cabinet with the low-temperature air outside. By using the setting of the adjustment assembly 4, the support base 45 is placed on the ground. According to the horizontal state, the screw rod 42 on the inner wall of the threaded sleeve 41 is rotated. The conical stabilizing sleeve 43 and the screw rod 42 are rotated by directly holding the operating handle 44. The screw rod 42 moves down along the threaded sleeve 41, and at the same time, it drives the conical stabilizing sleeve 43 and the support base 45 to move down. The conical stabilizing sleeve 43 surrounds the outer periphery of the support base 45, which can improve the stability of the PLC electrical control cabinet after placement. Four symmetrical adjustment assemblies 4 are set at the bottom of the control cabinet body 1, which can easily adjust the height of each corner to keep the internal equipment of the PLC electrical control cabinet in a horizontal state, so as to ensure continuous and stable operation.
[0030] Example 2 differs from Example 1 primarily in that: a PLC electrical control cabinet with a bottom support adjustment structure is provided. The adjustment component 4 includes a threaded sleeve 41 connected to the bottom of the control cabinet body 1. A screw rod 42 is threadedly connected to the inner wall of the threaded sleeve 41. A conical stabilizing sleeve 43 is fixedly connected to the surface of the screw rod 42. An operating handle 44 is fixedly connected to the surface of the conical stabilizing sleeve 43. A support base 45 is fixedly connected to the bottom end of the screw rod 42. The ventilation component 5 includes an installation sleeve 51 fixedly connected to the bottom of the inner wall of the control cabinet body 1. An air outlet pipe 52 is fixedly connected to the inner wall of the installation sleeve 51. Several air outlet holes are opened on the surface of the air outlet pipe 52. One end of the air outlet pipe 52 is connected to an air outlet pipe 53. A fan 54 is fixedly connected to the bottom of the control cabinet body 1. The air outlet of the fan 54 is connected to the bottom end of the air outlet pipe 53. A limit plate 59 is slidably connected to the bottom of the control cabinet body 1 through a dovetail groove. Anti-slip protrusions are provided on the surface of the limit plate 59. One side of the position plate 59 is in contact with one side of the disc 58, and the static friction between them is relatively large. The air inlet of the fan 54 is connected to the air inlet branch pipe 55 through the main air inlet pipe. An isolation ring 56 is fixedly connected to the inner wall of the air inlet branch pipe 55. A filter column 57 is movably connected to one side of the isolation ring 56. One end of the filter column 57 is fixedly connected to the disc 58. With the setting of the ventilation component 5, the PLC electrical control cabinet can draw low-temperature air from the bottom of the control cabinet body 1 through the air inlet branch pipe 55 set at the bottom. According to the thermodynamic principle, hot air is light and naturally rises. The low-temperature air at the bottom gradually heats up after passing through the working equipment and finally flows to the ventilation slots 3 on both sides of the top of the control cabinet body 1. The air travel is long, which can completely remove the heat generated by the equipment in the control cabinet body 1. The filter column 57 can filter the air. Replacement and maintenance can be completed by simply pulling the limit plate 59 and pulling out the filter column 57 to complete the replacement operation, which is convenient and quick.
[0031] There are two intake manifolds 55, both equipped with electrically controlled valves. When the filter element 57 in one intake manifold 55 is replaced, the other manifold can be guaranteed to complete the filtration operation normally.
[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0033] During installation, adjust the adjustment component 4 at the appropriate position according to the specific level. Rotate the conical stabilizing sleeve 43 by holding the operating handle 44, directly causing the screw rod 42 to move downwards along the threaded sleeve 41. Simultaneously, this moves the conical stabilizing sleeve 43 and the support base 45 downwards, extending the length of the adjustment component 4. When the equipment in the control cabinet body 1 is level, the operation is complete. Open the control cabinet body 1, and the fan 54 will start. Low-temperature air, filtered by the filter column 57, is then transported by the fan 54 to the outlet pipe 53 through the inlet pipe 55. The air outlet pipe 52 radiates into the control cabinet body 1 through the hole at the top of the air outlet pipe 52. The hot air rises and radiates outward through the ventilation slot 3. When the filter column 57 is dirty, slide the limit plate 59 to separate one side of the limit plate 59 from the disc 58. Pull the disc 58 outward to separate the filter column 57 from the air inlet pipe 55. Then insert the clean filter column 57 into the air inlet pipe 55 until one end of the filter column 57 contacts the isolation ring 56. Then continue to work. When the device has finished working, restore the device.
