[0021] EMBODIMENT

[0022] The following is further described in combination with specific embodiments, such as the attached Figure 1 - the attached Figure 6 ​As shown, the slag collecting pipe of the coal seam drilling blowout prevention system in the embodiment comprises a tank body 10 with an open upper end, a coiled pipe device 12 rotatably arranged at the upper end inside the tank body 10, a pipe 14 wound on the side of the coiled pipe device 12, and a through hole 11 formed in the sidewall of the upper end of the tank body 10. One end of the pipe 14 is arranged below the coiled pipe device 12, and the pipe 14 is arranged through the through hole 11. Specifically, in use, the gas, water, and slag generated during the drilling process enter the tank body 10 through the pipe 14. By rotating the coiled pipe device 12, the pipe 14 can be retracted or released, so that there is no U-shaped bend in the pipe 14 during the entire drilling process, and the water and slag are prevented from accumulating in the pipe 14, so that the pipe 14 always remains unobstructed. After retraction, the pipe 14 can also be temporarily stored in the tank body 10 in a spiral shape, so that the pipe 14 can be better stored, and the lower end of the pipe 14 is always inside the tank body 10, so that the original slag collection is not adversely affected.

[0023] The through hole 11 in the embodiment is vertically arranged in a long strip shape. Specifically, when the coiled pipe device 12 rotates, the pipe 14 can move up and down in the through hole 11, but the height of the coiled pipe device 12 itself does not change, so that the tank body 10 can be better sealed.

[0024] The lower end of the coiled pipe device 12 in the embodiment is provided with a connecting block 15, the lower end of the connecting block 15 is provided with a sealing plate 16, and the pipe 14 is arranged through the sealing plate 16. A sealing ring is arranged between the inner wall of the tank body 10 and the sealing plate 16. Specifically, the space at the bottom of the tank body 10 can be better sealed by the sealing plate 16 and the sealing ring to prevent gas leakage.

[0025] The inner wall of the tank body 10 in the embodiment is provided with a support ring 17, and the lower side of the sealing plate 16 abuts against the support ring 17. Specifically, the sealing plate 16, the coiled pipe device 12, and the pipe 14 can be better sealed by the support ring 17.

[0026] The sidewall of the coiled pipe device 12 in the embodiment is provided with a spiral-shaped clamping groove 13, and the pipe 14 is clamped in the clamping groove 13. Specifically, the pipe 14 can be better stored in this way.

Specifically, the coiled pipe device 12 can be more easily rotated by the lever 21.

[0028] The outer wall of the dialing rod 21 in the embodiment is sleeved with a sleeve 22, the lower end side wall of the sleeve 22 is hingedly provided with a clamping plate 23, and the upper end of the clamping plate 23 and the sleeve 22 are provided with an elastic sheet 24; the height of the lower end of the clamping plate 23 is lower than the height of the upper end surface of the tank body 10. Specifically, the upper end of the clamping plate 23 is subjected to the elastic force of the elastic sheet 24, so that the lower end is tightly abutted against the outer wall of the tank body 10, so that the coil pipe device 12 can be well fixed, and rotation of the coil pipe device 12 in the use process is avoided; by pinching the clamping plate 23 and the sleeve 22 by hand, the lower end of the clamping plate 23 is separated from the outer wall of the tank body 10, so that the coil pipe device 12 can be rotated.

[0029] In summary, the slag collecting pipe of the coal seam drilling blowout prevention system in the embodiment can make the gas, water, and slag generated in the drilling process enter the tank body 10 through the pipeline 14, and the pipeline 14 can be bunched or released by rotating the coil pipe device 12, so that the U-shaped bending part in the pipeline 14 is avoided as much as possible in the whole drilling process, the water and slag are avoided from being accumulated in the pipeline 14, the pipeline 14 can always keep unobstructed, and the pipeline 14 can also be temporarily stored in the tank body 10 in a spiral shape after being bunched, so that the pipeline 14 can be better stored, and the lower end of the pipeline 14 is always inside the tank body 10, so that the original slag collecting is not adversely affected.
