[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0027] like Figure 1 and Figure 2 As shown, the mining intrinsically safe substation 100 of the embodiment of the utility model includes a housing 1, a circuit board 2 and a terminal block 3, the circuit board 2 is connected to the housing 1, the terminal block 3 includes a base 31 and an adjustment base 32, the base 31 is connected to the circuit board 2, the adjustment base 32 is rotatably connected to the base 31, and the adjustment base 32 has an interface 321 for wiring.

[0028] In the mining intrinsically safe substation 100 of the embodiment of the utility model, the wiring terminals located at the edge of the circuit board 2 can be replaced by the wiring seat 3, wherein the interface 321 on the adjustment seat 32 is used for wiring with external equipment. During the wiring process, the adjustment seat 32 can be rotated relative to the base 31, and the adjustment seat 32 can be adjusted to a suitable angle, which is more convenient for the operator to connect the wiring. After the wiring is completed, the adjustment seat 32 can be rotated in the direction close to the base 31 to achieve reset, thereby improving the convenience of wiring.

[0029] The mining intrinsically safe substation 100 of the embodiment of the utility model includes a plurality of wiring terminals. The wiring operation of the wiring terminals located at the edge of the circuit board 2 is inconvenient. These wiring terminals can be replaced by the above-mentioned terminal holders 3. In other words, the above-mentioned terminal holders 3 are installed in the intrinsically safe substation 100 as a type of wiring terminals.

[0030] It is understandable that when the wiring operation of the wiring terminals located on the inner side of the circuit board 2 is inconvenient, the above-mentioned wiring seat 3 can also be used as a substitute to improve the convenience of wiring.

[0031] As an example, Figure 1 and Figure 2 As shown, the base 31 is fixedly connected to the circuit board 2, the interface 321 is arranged on the side of the adjustment base 32 away from the base 31, and the rotation axis of the adjustment base 32 relative to the base 31 is arranged away from the inner wall of the shell 1; therefore, when the adjustment base 32 is rotated relative to the base 31, the connector can be moved away from the inner wall of the shell 1, which is conducive to the wiring operation.

[0032] In some embodiments, the wiring socket 3 includes a damping member, which is used to provide a damping force for the rotation of the adjustment socket 32 ​​and the base 31 .

[0033] Through the above arrangement, the adjusting seat 32 is rotated relative to the base 31, and the adjusting seat 32 can stay at any position, which is more convenient for operators to perform wiring operations.

[0034] In some embodiments, Figure 2 As shown, the damping member is a damping shaft 33 , and the damping shaft 33 is passed through the adjustment seat 32 and the base 31 , and at least one of the adjustment seat 32 and the base 31 is interference fit with the damping shaft 33 .

[0035] The adjustment seat 32 is rotatably connected to the base 31 via the damping shaft 33 , which has low cost and simple structure, making the wiring seat 3 easy to assemble.

[0036] As an example, the damping shaft 33 passes through the adjustment seat 32 and is fixedly connected to the adjustment seat 32, and both ends of the damping shaft 33 extend out of the adjustment seat 32 and are respectively arranged on both sides of the base 31, and both ends of the damping shaft 33 are interference fit with the base 31. Therefore, during the rotation of the adjustment seat 32 relative to the base 31, the resistance between the damping shaft 33 and the base 31 is relatively large, so that the adjustment seat 32 can stay at any position that is convenient for wiring operation.

[0037] In some embodiments, the wiring socket 3 further includes a claw 34 , and the base 31 and the adjustment socket 32 ​​can be connected to each other through the claw 34 .

[0038] The clamping claw 34 can limit and fix the base 31 and the adjustment base 32 so that the two are stably connected to ensure the stability of the wiring base 3 and further ensure the stability of the wiring.

[0039] As an example, Figure 2 As shown, there are two claws 34 , which are arranged oppositely on both sides of the base 31 , and can fix the base 31 and the adjustment seat 32 on both sides, thereby further improving the stability of the connection between the base 31 and the adjustment seat 32 .

[0040] In some embodiments, Figure 2 and Figure 3 As shown, the claw 34 includes a fixing portion 341 and a clamping portion 342 connected to each other, the fixing portion 341 is connected to the base 31, the adjustment seat 32 has a clamping groove 322, and the clamping portion 342 is movable relative to the base 31 so that the clamping portion 342 can be clamped and matched with the clamping groove 322.

[0041] With the above arrangement, after wiring is completed, the adjustment seat 32 is rotated toward the base 31 , and when the engaging groove 322 is aligned with the clamping claw 34 , the clamping claw 34 is engaged with the engaging groove 322 , thereby limiting the position of the adjustment seat 32 .

[0042] Alternatively, if Figure 3 As shown, the claw 34 is made of elastic material, the fixing portion 341 is fixedly connected to the base 31, the clamping portion 342 is a hemispherical protrusion, and is integrally formed with the fixing portion 341; a groove wall of the clamping groove 322 forms a limiting surface 323, and after the clamping portion 342 is engaged with the clamping groove 322, the clamping portion 342 is located in the clamping groove 322, and the clamping portion 342 stops at the limiting surface 323 on the side facing the base 31.

[0043] Therefore, in the process of rotating the adjustment seat 32 toward the direction close to the base 31, the adjustment seat 32 abuts against the outer side surface of the clamping portion 342 and tends to move the clamping portion 342 outward (the fixing portion 341 undergoes elastic deformation). When the clamping groove 322 is aligned with the clamping portion 342, the fixing portion 341 is reset and drives the clamping portion 342 to engage with the clamping groove 322, thereby achieving a stable connection between the adjustment seat 32 and the base 31.

[0044] In some embodiments, the housing 1 is made of metal material.

[0045] It is known that in a mine environment, due to the presence of a large number of electrical equipment and a complex electromagnetic environment, the equipment is easily affected by various electromagnetic interferences, resulting in unstable or distorted signal transmission.

[0046] Since metal materials are conductive, the housing 1 is made of metal materials, so that the housing 1 can effectively reflect and absorb external electromagnetic fields, thereby reducing the impact on internal circuits and improving the anti-interference capability of the intrinsically safe substation 100.

[0047] Optionally, the housing 1 is made of a metal material with good electrical conductivity, such as aluminum alloy or stainless steel.

[0048] In some embodiments, the housing 1 includes a first shell and a second shell, the first shell and the second shell form a mounting cavity, the circuit board 2 and the terminal block 3 are both arranged in the mounting cavity, and the first shell and the second shell are connected by a bolt assembly.

[0049] Through the above arrangement, it is convenient to disassemble and assemble the circuit board 2, components, etc. in the housing 1, and it is easy to inspect and repair.

[0050] Optionally, the bolt assembly includes a bolt, a washer and a nut.

[0051] In this way, the stability of the connection between the first shell and the second shell can be ensured.

[0052] In some embodiments, the bolt assembly is a conductive bolt assembly.

[0053] The first shell and the second shell are connected by a conductive bolt assembly, so that the shell 1 as a whole forms a continuous shielding layer, thereby further improving the anti-interference capability of the intrinsically safe substation 100.

[0054] Optionally, the conductive bolt assembly includes a conductive bolt, a conductive washer and a conductive nut.

[0055] In some embodiments, Figure 1 As shown, the mine intrinsically safe substation 100 further includes a plurality of wiring terminals and a shielding shell 4, the wiring terminals are connected to the circuit board 2, and the shielding shell 4 is covered on the wiring terminals.

[0056] It is known that the connection ports and connecting wires on the connection terminals are also easy ways for electromagnetic interference to invade, resulting in unstable or distorted signal transmission.

[0057] By providing the shielding shell 4, the connection port of the connection terminal can be partially shielded for a second time, thereby reducing electromagnetic interference on the signal and ensuring the purity of the signal.

[0058] Optionally, a shielding shell 4 is provided on the wiring seat 3 .

[0059] In some embodiments, the mine intrinsically safe substation 100 further includes a power module, the power module has a power input terminal, and a filter is provided at the power input terminal.

[0060] Through the above settings, the filter can filter out high-frequency noise and clutter in the power grid, ensuring that the power input to the intrinsically safe substation 100 is pure and stable, thereby improving the stability and reliability of the system and ensuring the normal operation of the coal mine safety monitoring system.

[0061] Optionally, the power module adopts a power module designed for a wide voltage range.

[0062] Therefore, it can be ensured that in the case of large voltage fluctuations, the intrinsically safe substation 100 can still obtain a stable operating voltage to adapt to the complex voltage fluctuations in the coal mine and reduce the interference of power supply noise on system operation.

[0063] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
