Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a mine electrical moisture-proof protection device. Background Art

[0002] The operation of mining equipment requires the cooperation of a variety of electrical equipment to achieve power supply and circuit stability. Most of the electrical equipment is installed in an electrical box. Since the equipment inside the electrical box generates heat, heat dissipation holes are opened on the electrical box. The heat dissipation holes accelerate air circulation, causing moisture in the air to enter the electrical box. The humid environment will corrode the insulating surface of the electrical equipment and cause short circuit problems. Therefore, moisture-proof protective devices are required.

[0003] In order to dissipate the heat generated inside the protective device, a ventilation structure is usually provided inside the protective device. However, although the existing ventilation structure realizes ventilation treatment inside and outside the protective device, it will cause the inside of the protective device to become damp. If this continues for a long time, it will affect the service life of the components inside the protective device. Therefore, further improvements are needed on this basis. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0025] A protective housing 1, wherein a ventilation structure is installed inside the housing, and the ventilation structure is used to achieve ventilation and moisture-proof treatment of the electrical equipment inside the protective housing 1;

[0026] A linkage assembly, which is rotatably connected to the inside of the protective shell 1 and is transmission-connected to the ventilation structure, and is used to realize the driving adjustment of the ventilation structure;

[0027] Compared with the prior art, the transmission coordination between the ventilation structures is achieved through the linkage components, so that the protective shell 1 can be ventilated with the external environment. At the same time, the components inside the protective shell 1 can be separated from the outside world through the setting of the adjustment plate 15, which not only has a ventilation effect, but also can achieve a moisture-proof effect, thereby increasing the service life of the electronic components inside the protective shell 1.

[0028] See also Figure 1-Figure 3 In one embodiment, the ventilation structure comprises:

[0029] A first mounting frame 2 and a second mounting frame 6, wherein the first mounting frame 2 and the second mounting frame 6 are fixedly mounted on the top of the inner portion of the protective housing 1, and a first air inlet 3, a first air outlet 4, a second air inlet 7 and a second air outlet 8 are respectively disposed at two ends of the first mounting frame 2 and the second mounting frame 6;

[0030] The first installation axis 9 and the second installation axis 10 are respectively rotatably mounted on the middle of the first installation frame 2 and the second installation frame 6. The middle of the first installation axis 9 and the second installation axis 10 are fixedly connected with a mounting block 14. The side of the mounting block 14 is hingedly provided with a plurality of adjustment plates 15. The adjustment plates 15 slide along the path of the annular guide rail 16 in the middle of the first installation frame 2 and the second installation frame 6.

[0031] In order to prevent the electronic components inside the protective shell 1 from generating too much heat due to long-term use, the installation shaft 9 inside the first installation frame 2 is controlled to rotate, and the installation shaft 9 then drives the installation block 14 to rotate. Through the rotation of the installation block 14, the adjustment plate 15 can rotate around the installation block 14, and one side of the adjustment plate 15 can slide along the annular guide rail 16 path in the middle of the first installation frame 2. By compressing the gas inside the first installation frame 2, the outdoor gas can enter the first installation frame 2 through the first air inlet 3, and finally be discharged into the protective shell 1 through the first exhaust port 4.

[0035] See also Figure 1-Figure 2 In one embodiment, a drying box 5 is provided at the top of the protective housing 1 between the first mounting frame 2 and the second mounting frame 6, and a desiccant is provided inside the drying box 5;

[0036] The mounting block 14 is driven to rotate by the mounting shaft 19, and the transmission wheel 11 at one end outside the first mounting frame 2 also rotates accordingly. Since the transmission wheel 11 and the transmission wheel 2 12 are connected through the transmission member 13, the mounting shaft 2 10 can be further driven to rotate, and the mounting shaft 2 10 further drives the mounting block 14 inside the second mounting frame 6 to rotate. Through the rotation of the mounting block 14, the adjustment plate 15 can rotate around the mounting block 14, and one side of the adjustment plate 15 slides along the path of the annular guide rail 16 in the middle of the second mounting frame 6, and the gas inside the second mounting frame 6 is adjusted. By performing compression processing, the gas inside the protective shell 1 can enter the second mounting frame 6 through the second air inlet 7, and finally be discharged to the external environment of the protective shell 1 through the second exhaust port 8, thereby realizing ventilation adjustment inside the protective shell 1. When the inside of the protective shell 1 is not ventilated during normal times, the adjustment plate 15 can be used to separate the inside of the protective shell 1 from the outside, thereby playing a moisture-proof role. By arranging a drying box 5 between the first mounting frame 2 and the second mounting frame 6 of the protective shell 1, the moisture-proof effect of the inside of the protective shell 1 can be further improved.

[0037] See also Figure 2 In addition to the above technical solution, the utility model also provides another embodiment, which is different from the above embodiment in that a flange is provided at the fixed connection between the first mounting frame 2 and the second mounting frame 6 and the protective shell 1, which can improve the sealing performance between the first mounting frame 2 and the second mounting frame 6 and the protective shell 1.

Through the rotation of the installation block 14, the adjustment plate 15 can rotate around the installation block 14, and one side of the adjustment plate 15 slides along the path of the annular guide rail 16 in the middle of the first installation frame 2. By compressing the gas inside the first installation frame 2, the outdoor gas can enter the first installation frame 2 through the first air inlet 3 and finally be discharged into the protective shell 1 through the first exhaust port 4. The installation block 14 is driven to rotate by the installation shaft 19, and the transmission wheel 11 located at one end of the outside of the first installation frame 2 also rotates accordingly. Since the transmission wheel 11 and the transmission wheel 2 12 are connected through the transmission member 13, the installation shaft 2 1 can be further driven. 0 rotates, the mounting shaft 10 further drives the mounting block 14 inside the second mounting frame 6 to rotate, and through the rotation of the mounting block 14, the adjusting plate 15 can rotate around the mounting block 14, while one side of the adjusting plate 15 slides along the path of the annular guide rail 16 in the middle of the second mounting frame 6, and by compressing the gas inside the second mounting frame 6, the gas inside the protective shell 1 can enter the second mounting frame 6 through the second air inlet 7, and finally be discharged to the external environment of the protective shell 1 through the second exhaust port 8, so as to realize the ventilation adjustment inside the protective shell 1, and when the inside of the protective shell 1 is not ventilated at ordinary times, the inside of the protective shell 1 can be separated from the outside by the arranged adjusting plate 15, so as to play a moisture-proof role, and by arranging the drying box 5 between the first mounting frame 2 and the second mounting frame 6 of the protective shell 1, the moisture-proof effect inside the protective shell 1 can be further improved.
