Description

Technical Field

They are used for power and lighting distribution and motor control, and are suitable for indoor wall mounting or outdoor floor mounting. Intrinsically safe control boxes are a type of control box commonly used in mine construction. Existing intrinsically safe control boxes are typically sealed to improve dustproof performance, resulting in poor heat dissipation efficiency and a large temperature difference between the inside and outside of the device. This temperature difference can cause condensation inside the device, leading to internal dampness and potentially short circuits. Furthermore, most existing intrinsically safe control boxes are inconvenient to disassemble and maintain. Therefore, improvements to the existing equipment are necessary to address these issues.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1-6 This invention provides a technical solution: an intrinsically safe double-layer dustproof and explosion-proof control box for mining, such as... Figure 1 , Figure 2 and Figure 6As shown, a mounting bracket 2 is provided inside the control box body 1, and both the mounting bracket 2 and the control box body 1 are mounted on the support plate 11. Electrical components are mounted on the mounting bracket 2, and the mounting bracket 2 is fixedly mounted on the support plate 11. Meanwhile, the support plate 11 is connected to the bottom of the control box body 1 through a connector 28. The operator can separate the control box body 1 from the support plate 11 by disassembling the connector 28, which facilitates the operator to inspect and maintain the electrical components inside the control box body 1, and the disassembly and installation process is relatively simple.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, a top plate 3 is connected to the top of the control box body 1. A control panel is provided on the front side of the top plate 3, and a first motor 13 is provided inside the top plate 3. A timer device 26 is provided on one side of the first motor 13. The timer device 26 is electrically connected to the controller, the first motor 13, the cooling fan 22 and the second motor 25. The timer device 26 facilitates the timed start of the first motor 13, the electric telescopic rod 18, the cooling fan 22 and the second motor 25 to perform corresponding decondensation and heat dissipation work, thereby preventing the internal temperature of the device from becoming too high.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the output end of the first motor 13 is connected to the top of the rotating shaft 6. The first motor 13, the rotating shaft 6, the fan blade assembly 7, the connecting frame 8, the first absorbent sponge 9, and the second absorbent sponge 10 constitute a rotating structure. Under the driving action of the first motor 13, the rotating shaft 6 will drive the fan blade assembly 7 and the connecting frame 8 to rotate. The rotating fan blade assembly 7 will quickly dissipate the heat inside the device to the outside, thereby facilitating heat dissipation of the device. On the other hand, the rotating connecting frame 8 will drive the first absorbent sponge 9 and the second absorbent sponge 10 to absorb and clean the condensation on the inner wall and the inner top of the control box body 1, thereby preventing it from falling onto electrical components and thus preventing accidental short circuits. The fan blade assembly 7 is located above the mounting frame 2.

[0042] like Figure 1 and Figure 2 As shown, the bottom end of the rotating shaft 6 passes through the through hole 5 at the top of the control box body 1 and is connected to the fan blade assembly 7. A dustproof net 4 is provided between the control box body 1 and the top plate 3, and the dustproof net 4 is located on the outside of the rotating shaft 6. The dustproof net 4 plays a role in preventing dust, thereby preventing dust from entering the device through the through hole 5 at the rotating shaft 6, and thus preventing dust from contaminating the electrical components inside the device.

[0043] like Figure 1 and Figure 2As shown, the rotating shaft 6 is connected to the first absorbent sponge 9 and the second absorbent sponge 10 via the connecting frame 8. Two sets of the first absorbent sponge 9 and the second absorbent sponge 10 are symmetrically arranged. The side of the first absorbent sponge 9 and the second absorbent sponge 10 away from the connecting frame 8 respectively contacts the side wall and the inner top of the control box body 1, so as to facilitate the absorption of condensation on the side wall and the inner top of the control box body 1 by using the first absorbent sponge 9 and the second absorbent sponge 10.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, the second motor 25 is installed inside the base 12, and bolt holes are symmetrically provided on the base 12. The operator can use external bolts to install and fix the device by passing through the bolt holes. The top of the base 12 is connected to the bottom of the support plate 11 through a fixing bracket. The output end of the second motor 25 is connected to the support plate 16 through the bracket 14. The bracket 14 is connected to the support plate 16 through the rotating groove 15, and the rotating groove 15 is provided on the support plate 11. At the same time, the top of the support plate 16 is provided with a sliding groove 27. The second motor 25 can drive the bracket 14 and the support plate 16 to rotate, thereby adjusting the position of the protective plate 19, so as to make the protective plate 19 meet different usage requirements. The rotating groove 15 provides a moving path for the rotation of the bracket 14.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a support plate 17 is connected to the outer side of the support plate 16. The support plate 16 is symmetrically arranged on both sides of the control box body 1. An electric telescopic rod 18 is provided on the outer side of the support plate 17. The other end of the electric telescopic rod 18 passes through the support plate 17 and is connected to the protective plate 19. The protective plate 19 includes a rubber layer 1901. A sponge layer 1902 is provided on the inner side of the rubber layer 1901. A foam board layer 1903 is provided on the inner side of the sponge layer 1902. This facilitates the improvement of the device's anti-collision, noise reduction, and heat insulation performance through the rubber layer 1901, sponge layer 1902, and foam board layer 1903.

[0046] like Figure 1 , Figure 3 and Figure 4 As shown, the protective plate 19 is enclosed in a cylindrical shape, which facilitates the protection of the control box body 1 and electrical components inside. The bottom of the protective plate 19 is connected to a slider 24, which is set in a groove 27. The operator can move the protective plate 19 by controlling the electric telescopic rod 18, so that the protective plate 19 can be moved away from the control box body 1, thereby facilitating the maintenance of the electrical components inside the control box body 1.

[0047] like Figure 1 and Figure 3As shown, the protective plate 19 and the control box body 1 are respectively provided with heat dissipation holes 23, and the heat dissipation holes 23 are correspondingly set with the heat dissipation fan 22 on the mounting plate 21. At the same time, the mounting plate 21 is connected to the outer wall of the protective plate 19 through the connecting column 20. The heat dissipation fan 22 can exhaust air into the control box body 1 through the heat dissipation holes 23, thereby facilitating the heat dissipation of the internal electrical components and thus preventing the electrical components from overheating and failing.

[0048] In use, the electrical components are installed on the mounting bracket 2, and then the control box body 1 is fixed to the support plate 11 using the connector 28 to protect the electrical components. Then, the electric telescopic rod 18 is controlled to move the protective plate 19 inside the box to surround and protect the control box body 1. The timing device 26 will start the first motor 13, the cooling fan 22 and the second motor 25 at regular intervals through the controller. The first motor 13 will drive the fan blade assembly 7, the first absorbent sponge 9 and the second absorbent sponge 10 to rotate. The rotating fan blade assembly 7 can quickly dissipate the heat dissipated by the electrical components inside the control box body 1. At the same time, the rotating first absorbent sponge 9 and the second absorbent sponge 10 can wipe and clean the condensation on the top and inner side walls of the control box body 1. On the other hand, the second motor 25 will drive the protective plate 19 to rotate so that the heat dissipation hole 23 on its top coincides with the heat dissipation hole 23 on the side wall of the control box body 1. Then, the cooling fan 22 will exhaust air through the heat dissipation hole 23 to help the device dissipate heat.
