[0022] Example 1

[0023] like Figures 1-4 As shown in the figure, the high and low voltage control cabinet proposed in this embodiment includes a lower housing 1, an upper housing 2, multiple intermediate housings 3, and multiple sets of connecting components.

[0024] The lower housing 1 has openings at its top and front, and a first sealing groove 101 is provided at its upper end. A first door 41 is rotatably mounted on the front of the lower housing 1, and a third sealing groove 411 is provided at its upper end. The middle housing 3 has openings at its top, bottom, and front, and a first sealing strip 9 is provided at its lower end, with a second sealing groove 301 at its upper end. A third door 43 is rotatably mounted on the front of the middle housing 3, with a second sealing strip 10 at its lower end and a fourth sealing groove 431 at its upper end. The upper housing 2 has openings at its bottom and front, and a first sealing strip 9 is provided at its lower end. A second door 42 is rotatably mounted on the front of the upper housing 2, with a second sealing strip 10 at its lower end.

[0025] The lower housing 1 and the intermediate housing 3, the two adjacent intermediate housings 3, and the intermediate housing 3 and the upper housing 2 are all detachably connected by connecting components. The connecting components include a U-shaped limiting member 12, a sliding plate 13, a positioning rod 14, a wedge block 15, a guide rod 16, and a spring 17. The U-shaped limiting member 12 and the sliding plate 13 are respectively installed on two adjacent components. The guide rod 16 is located in the sliding groove of the sliding plate 13. The end of the positioning rod 14 is slidably located in the sliding groove of the sliding plate 13 and is slidably connected to the guide rod 16. The spring 17 is sleeved on the guide rod 16. The wedge block 15 is connected to the end of the positioning rod 14.

[0026] The lower housing 1 and the upper housing 2 are respectively provided with a second vent pipe 72 and a first vent pipe 71. The inner side of the first vent pipe 71 and the second vent pipe 72 are both provided with dustproof nets. The inner side of the first vent pipe 71 is also equipped with a cooling fan 11. The inner side of the upper housing 2 is equipped with a temperature sensor and a PLC controller. The temperature sensor can detect the internal temperature of the control cabinet and feed the signal back to the PLC controller. When the temperature rises above the set threshold, the PLC controller controls the switch to turn on the cooling fan 11 to accelerate the air exchange speed inside the control cabinet.

[0027] Specifically, the technical solution can form control cabinets of different heights by setting up a lower shell 1, an upper shell 2 and multiple intermediate shells 3, which can be used for the installation of a large number of electronic components, and is easy to disassemble and assemble, with strong applicability.

[0028] The following is the installation and assembly process of the control cabinet: First, install the intermediate housing 3 and the lower housing 1, aligning the intermediate housing 3 with the lower housing 1, and ensuring that the third door 43 is aligned with the first door 41. Insert the first sealing strip 9 at the bottom of the intermediate housing 3 into the inner side of the first sealing groove 101, and insert the second sealing strip 10 at the bottom of the third door 43 into the inner side of the third sealing groove 411. Select the number of intermediate housings 3 to install according to the installation height of the control cabinet. When installing and splicing multiple intermediate housings 3, ensure that the upper and lower intermediate housings 3 are vertically aligned, and that the first sealing strip 9 of the upper intermediate housing 3 is engaged with the lower one. In the second sealing groove 301 of the intermediate housing 3, it is also necessary to ensure that the upper and lower third doors 43 are aligned so that the second sealing strip 10 on the upper third door 43 is inserted into the fourth sealing groove 431 of the lower third door 43. Then, the multiple intermediate housings 3 are installed in accordance with the above method. When connecting the intermediate housing 3 and the upper housing 2, the upper housing 2 is aligned with the intermediate housing 3 and the second door 42 is aligned with the third door 43 so that the first sealing strip 9 at the bottom of the upper housing 2 is inserted into the inner side of the second sealing groove 301 and the second sealing strip 10 on the second door 42 is inserted into the inner side of the fourth sealing groove 431.

[0029] During installation, multiple sets of connecting components are used to achieve fixed connections between the lower housing 1 and the intermediate housing 3, between the intermediate housing 3 and the upper housing 2, and between two adjacent intermediate housings 3. When the wedge block 15 is inserted into the insertion hole of the U-shaped limiting member 12, the inclined surface of the wedge block 15 contacts the end of the insertion hole. As the positioning rod 14 gradually moves downward, it forces the spring 17 to compress and moves the positioning rod 14. When the wedge block 15 moves to the lower end of the U-shaped limiting member 12, the positioning rod 14 is driven to reset under the elastic force of the spring 17, so that the wedge block 15 is stuck at the lower end of the U-shaped limiting member 12, thereby completing the limiting connection of the two corresponding components. When releasing the fixation, it is only necessary to push the wedge block 15 to the position directly below the inner side of the insertion hole, and then separate the slide plate 13 from the U-shaped limiting member 12.

[0030] Example 2

[0031] like Figure 3 , Figure 5 as well as Figure 6 As shown, this embodiment of the high and low voltage control cabinet, compared with the first embodiment, further includes multiple equipment mounting plates 5 arranged side by side. Each equipment mounting plate 5 has a hollow structure. Except for the uppermost equipment mounting plate 5, each of the four corners at the top and bottom of the other multiple equipment mounting plates 5 has a second vent 501 communicating with its inner cavity. The uppermost equipment mounting plate 5 also has a second vent 501 communicating with its inner cavity at the four corners at the bottom. The lower housing 1 has a first vent 102 at the four corners at its bottom. Four sets of support pipe assemblies are arranged between adjacent equipment mounting plates 5, and the inner cavities of adjacent equipment mounting plates 5 are connected through the support pipe assemblies. Each support pipe assembly includes an internally threaded pipe 61, a bottom pipe 62, and an externally threaded pipe 63. The bottom pipe 62 and... The lower end of the internally threaded tube 61 is connected, and the externally threaded tube 63 is threadedly connected to the internally threaded tube 61. Both the bottom tube 62 and the externally threaded tube 63 are clearance-fitted with the second vent hole 501. The ends of the bottom tube 62 and the externally threaded tube 63 are respectively provided with a first limiting ring 18 and a second limiting ring 19. External gas enters the inner side of the support tube assembly through the first vent hole 102, and then enters the inner cavity of the equipment mounting plate 5 through the support tube assembly, thereby increasing the contact area between the equipment mounting plate 5 and the external air, which helps to achieve the purpose of rapid heat exchange. In the technical solution, the height of the support tube assembly can be adjusted by rotating the externally threaded tube 63, thereby adjusting the distance between two adjacent equipment mounting plates 5 to accommodate the installation of electrical components of different sizes. It should be noted that the electrical components are mounted on the equipment mounting plate 5.

[0032] T-shaped slide rails 8 are provided on the inner walls of the lower housing 1, the upper housing 2, and the intermediate housing 3. The T-shaped slide rails 8 on the inner side of the upper housing 2 do not extend to the top of the upper housing 2. T-shaped holes 502 are provided on multiple equipment mounting plates 5. When installing the equipment mounting plates 5, the T-shaped holes 502 are vertically aligned with the T-shaped slide rails 8, so that the T-shaped slide rails 8 are inserted into the inner side of the T-shaped holes 502, thereby guiding the equipment mounting plates 5.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
