[0002] A controller refers to a main command device that controls the starting, speed regulation, braking and reversing of a motor by changing the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order. It is composed of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire computer system. The intrinsically safe type is also called the intrinsically safe type. It is the safest type of all explosion-proof types. Intrinsically safe products cannot cause explosions of flammable and explosive gases in the surrounding environment regardless of internal short circuits or short circuits. Among them, intrinsically safe controllers for mining are mainly used in underground mining scenarios and are responsible for controlling the normal operation of related devices.

[0003] According to the search, the authorization announcement number CN 206657198 U announced a mine intrinsically safe controller, the outer side wall of the box is provided with a grounding assembly, which is composed of a No. 3 screw, an elastic washer, a flat washer and a grounding mark; the No. 3 screw is fixed on the connecting plate of the side wall of the box, the elastic washer and the flat washer are both inserted on the No. 3 screw, and the grounding mark is set on the outer surface of the No. 3 screw; the other side of the outside of the box is provided with a waterproof joint, and the inner side wall of the box is provided with a hexagonal nut; the upper part of the box is fixed with a box cover by several No. 1 screws, and the inside of the box is fixed with a circuit board mounting plate by No. 2 screws, and the circuit board mounting plate is fixed with a carrier board by bolts, which is an embedded computer carrier board.

[0038] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0039] Working principle: When in use, first install the installation box 1 into the mine through the installation base 25. Then, just align the two fixing blocks 302 at the bottom of the intrinsically safe controller body 3 with the openings on the installation box 1 and insert them. The bottom of the control panel 305 abuts against the protection frame 2, and the positioning plate 10 is inserted into the positioning groove 9. Then, turn the operating shaft 19. The operating shaft 19 drives the driven bevel gear 18 meshing with it to rotate through the driving bevel gear 20. The driven bevel gear 18 drives the connected transmission shaft 15 to rotate. The transmission shaft 15 drives another transmission shaft 15 to rotate through the synchronous pulley 21 and the synchronous belt 22.

If disassembly and assembly are required, just operate in the reverse direction; Then insert the external wiring cable into the protection frame 2 through the conduit 23 and connect it to the wiring socket 304. Then fix it firmly through the sealing flange 24 and prevent dust and impurities from entering its interior. Then install the dynamic dust-proof component 5 on the two connecting frames 604 through bolts and make it closely adhere to the outer wall of the control panel 305. At the same time, the dust-proof strip 503 abuts against its outer wall. Fix it firmly by inserting the insertion rod 705 into the insertion hole 702. At this time, the relevant buttons on the control panel 305 can be operated. After the operation is completed, just pull the two handles 707 to drive the limiting plate 704 and the insertion rod 705 away from the insertion hole 702. After the insertion hole 702 loses its restraint, it will drive the dynamic dust-proof component 5 to move under the elastic force of the first spring 606, so that the U-shaped plug 502 is inserted into the U-shaped closed groove 402 to complete the closed dust-proof work.
