[0027] An embodiment of a multi-interface intrinsically safe mining acquisition structure of the present utility model is as Figures 1 to 3 shown. The device includes: a housing 1, a sealing plate 2 provided on the top of the housing 1, a plurality of aviation sockets 3 provided on the housing 1, an aviation plug 4 cooperatively connected with the plurality of aviation sockets 3, an armored socket 5 provided on the housing 1, and an armored plug 6 cooperatively connected with the armored socket 5; the plurality of aviation plugs 4 are respectively connected to different sensors; the armored plug 6 is connected to a cable accessing an explosion-proof electric control box;

[0028] A rotating assembly connected to a shearer is provided at the bottom of the housing 1;

[0029] A circuit board is provided in the housing 1. The plurality of aviation sockets 3 are electrically connected to the circuit board, and the circuit board is electrically connected to the armored socket 5.

[0030] In this embodiment, it should be noted that the housing 1 can rotate slightly relative to the shearer through the rotating assembly.

[0031] In this embodiment, the plurality of aviation sockets 3 are arranged in a rectangular array.

[0032] In this embodiment, it should be noted that the plurality of aviation sockets are arranged in a rectangular array so as to arrange as many aviation sockets as possible within a limited range.

[0033] In this embodiment, the armored socket 5 and multiple aviation sockets 3 are arranged on the same side of the housing 1. The housing 1 is in a stepped shape, and the width of the housing 1 where the armored socket 5 is arranged is smaller than the width of the housing 1 where the multiple aviation sockets 3 are arranged.

[0034] In this embodiment, it should be noted that the armored socket 5 and multiple aviation sockets 3 are arranged on the same side of the housing 1. At the same time, the housing 1 is in a stepped shape. This layout can make the overall structure more compact and occupy a smaller space range.

[0035] In this embodiment, the rotating assembly includes a circular chassis 71 installed on the shearer and a circular chuck 72 installed at the bottom of the housing 1. The circular chuck 72 is rotatably connected to the circular chassis 71.

[0036] In this embodiment, it should be noted that the top of the circular chuck 72 is welded to the bottom of the housing 1. The bottom of the circular chassis 71 has an outward-extending outer edge, and threaded holes are evenly distributed on the outer edge. The circular chassis 71 is fixed to the shearer by screws passing through the threaded holes.

[0037] In this embodiment, the outside of the circular chuck 72 is wrapped with an elastic buffer sheet.

[0038] In this embodiment, it should be noted that the elastic buffer sheet can reduce the vibration borne by the housing 1.

[0039] In this embodiment, two sector-shaped ring grooves 711 are formed in the circular chassis 71 centered on the center of the circle. The outer arc length dimension of the lower part of the sector-shaped ring groove 711 is larger than the outer arc length dimension of the upper part;

[0040] At the bottom of the circular chuck 72, two sector-shaped ring telescopic rods 73 with a rectangular cross-section are respectively vertically connected by two arc-shaped panels 74. The outer arc length dimension of the arc-shaped panel 74 is smaller than the outer arc length dimension of the sector-shaped ring groove 711;

[0042] When this embodiment is actually used, an external force is applied to compress the two sector-shaped ring telescopic rods 73, and then they are respectively inserted into the bottom of the two sector-shaped ring grooves 711. After removing the external force, the sector-shaped ring telescopic rods 73 are completely inserted into the lower part of the sector-shaped ring grooves 711. Since the outer arc length dimension of the arc-shaped panel 74 is smaller than the outer arc length dimension of the sector-shaped ring groove 711, the circular chuck 72 can rotate slightly relative to the circular chassis 71.

[0043] In this embodiment, the sector-shaped telescopic rod 73 includes a solid rod 731 and a hollow rod 732 sleeved outside the solid rod 731. The solid rod 731 can slide along the hollow rod 732, and the inner end of the solid rod 731 is elastically connected to the inner wall of the end of the hollow rod 732.

[0044] In this embodiment, the upper part of the sealing plate 2 presses on the top of the housing 1, and the outer side wall of the lower part of the sealing plate 2 abuts against the inner side wall of the housing 1.
