Description

[0002] In today's society, the demand for gas control is becoming more and more urgent. High-gas and soft coal seams have become a major hidden danger that cannot be ignored in coal mine safety production. Frequent coal and gas outburst accidents not only seriously threaten the lives and safety of miners, but also greatly interfere with the normal production order of coal mines. Therefore, strengthening gas control in high-gas and soft coal seams and effectively eliminating the danger of coal and gas outbursts have become important tasks that need to be urgently solved in the field of coal mine safety production.

[0003] However, the current application of hydraulic punching technology in high-gas soft coal seams still faces some challenges. The fixed design of the nozzle limits its flexibility, making it impossible for operators to quickly replace it according to the real-time changes in the coal seam geological conditions and gas content. In addition, since the nozzle cannot be adjusted accordingly according to the actual coal seam conditions, the effect of hydraulic punching technology in depressurizing and increasing the permeability of coal seams is limited, which in turn affects its practicality and applicability.

The limited flow direction of the one-way valve 5 is that the flow from the flow regulating mechanism 3 flows in the direction of the three-way intersection of the multi-port pipe body 1. The boosting mechanism 7 is arranged in the boosting box 6. The nozzle head 8 is installed below the third pipeline 103 through the quick-release mechanism 9 and is connected to the third pipeline 103 .

[0035] See also Figure 2 and Figure 3 The flow regulating mechanism 3 includes: a first stepper motor 301, a first transmission gear set, a fixed plate with holes 303, and a blocking set. Figure 2 The direction indicated by the hollow arrow is the flow direction of the fluid.

[0036] The first stepper motor 301 is fixed on the mounting plate 2, and the first stepper motor 301 drives the first transmission gear set to rotate. The first transmission gear set includes a first gear 302 fixedly connected to the output end of the first stepper motor 301, and a gear ring 305 coaxially arranged with the perforated fixing plate 303 and located inside the multi-port tube body 1, and the gear ring 305 is meshed with the first gear 302 for transmission. The diameter of the gear ring 305 is larger than the diameter of the first gear 302, and a deceleration effect is played through the first transmission gear set.

[0037] The perforated fixing plate 303 is arranged inside the pipeline and fits with the inner wall of the pipeline. An adjustment hole 310 is arranged in the middle of the perforated fixing plate 303. The blocking group is composed of a plurality of blocking members 309 evenly distributed in a circle. The blocking members 309 fit with the perforated fixing plate 303. The blocking members 309 are driven to rotate by the first transmission gear group. The blocking members 309 rotate so that the blocked area of ​​the adjustment hole 310 changes accordingly. In this embodiment, there are five blocking members 309, and the shapes of the blocking members 309 are as follows: Figure 3 As shown, but not limited thereto, in other embodiments, the shape and quantity of the blocking members can be set according to actual needs.

[0038] See also Figure 3The gear ring 305 is provided with a plurality of sliding holes 306 evenly distributed around the circumference. One end surface of the fixed plate 303 with holes is provided with a plurality of fixed rods 304 evenly distributed around the circumference. The fixed rods 304 pass through the sliding holes 306 one by one. The rotation of the gear ring 305 drives the fixed plate 303 with holes to rotate. Each blocking member 309 is provided with a first connecting hole 309a and a second connecting hole 309b. A connecting rod 308 is installed and fixed in the first connecting hole. A connecting rod 307 is connected and fixed to the end of the connecting rod 308. The connecting hole 307a on the connecting rod 307 is rotatably connected to the end surface of the gear ring 305 through a pin shaft, and the second connecting hole is rotatably connected to the fixed plate 303 with holes through a pin shaft.

[0039] See also Figure 4 A sealing box 4 is also fixed to the outer circumference of the multi-port tube body 1, and the first gear 302 is located in the sealing box 4. The multi-port tube body 1 is also provided with a tube wall through groove 311, and the first gear 302 is meshed with the gear ring 305 inside the pipeline through the tube wall through groove 311.

[0040] In the adaptively adjustable gas-liquid mixing nozzle device of the embodiment, the internal blocking area of ​​the first pipe 101 and the second pipe 102 can be adjusted accordingly through the flow regulating mechanism 3, so as to adjust the fluid flow inside the pipe or perform preliminary pressurization. First, the first stepper motor 301 is turned on, and the first stepper motor 301 drives the first gear 302 to rotate, and then drives the gear ring 305 to rotate. The rotation of the gear ring 305 causes the fixing rod 304 of the fixed plate with holes to slide along the sliding hole 306 of the gear ring. When the gear ring 305 rotates, it will drive the blocking members 309 to rotate. The rotation of these blocking members 309 causes the blocked area of ​​the adjustment hole 310 to change accordingly, so as to adjust the flow of the fluid in the first pipe 101 and the second pipe and complete the preliminary pressurization.

[0041] See also Figure 5 and Figure 6 The boost mechanism 7 includes: a second stepping motor 701 , a second transmission gear set, a threaded rod 704 , a movable block 705 , a hollow tube 710 , a boost head 711 , and a boost groove 713 .

[0042] The inside of the booster box 6 is provided with a first partition plate 601 and a second partition plate 603 from top to bottom. The first partition plate 601 is provided with a partition plate through hole 602. The second partition plate 603 is provided with a hollow tube through hole.

[0043] The second stepper motor 701 is fixedly mounted on the top surface of the boost box 6, and the output shaft of the second stepper motor 701 extends into the interior of the boost box 6. The gear surface of the second transmission gear set is horizontally arranged and driven to rotate by the second stepper motor 701. The second transmission gear set is located in the space above the first partition 601. The second transmission gear set includes a second gear 702 and a third gear 703. The second gear 702 is fixedly connected to the output end of the second stepper motor 701, and the third gear 703 is meshed with the second gear 702. Preferably, as Figure 5 As shown, a bearing 709 is fixed on the boost box 6, and the third gear 703 is a gear with a shaft, and the upper end shaft of the third gear 703 is inserted into the bearing 709 and is rotatably connected to the bearing. The diameter of the third gear 703 is larger than the diameter of the second gear 702, and a deceleration effect is achieved through the second transmission gear set.

[0044] The threaded rod 704 is connected to the bottom of the third gear 703 and is driven to rotate by the third gear 703, and the threaded rod 704 passes through the partition through hole 602 and extends to the bottom of the first partition 601. A sliding rod 706 is connected and fixed to the lower surface of the first partition 601, and a baffle 707 is provided at the end of the sliding rod 706 away from the first partition 601. The movable block 705 is threadedly connected to the threaded rod 704, and a first slider 708 is fixedly connected to one side of the movable block 705, and the first slider 708 is slidably connected and installed on the sliding rod 706.

[0045] The hollow tube 710 is connected and fixed to the bottom surface of the movable block 705. The hollow tube 710 extends into the lower part of the second partition plate 603 through the hollow tube through hole, and a sealing ring 604 is provided at the intersection of the hollow tube 710 and the second partition plate 603. The boosting head 711 is connected and fixed to the lower part of the hollow tube 710. The inner wall of the third pipeline 103 is fixedly connected with a sealing plate 712, and a boosting groove 713 is provided on the sealing plate 712, and the boosting groove 713 is adapted to the boosting head 711.

[0046] In the adaptively adjustable gas-liquid mixing nozzle device of the embodiment, the fluid (water flow and gas) in the multi-port tube body can be enhanced by the boosting mechanism 7. First, the second stepper motor 701 is turned on, and the second stepper motor 701 drives the second gear 702 to rotate, and then drives the third gear 703 to rotate. When the third gear 703 rotates and drives the threaded rod 704 to rotate, the first slider 708 fixed to the movable block 705 rises or falls along the direction of the slider 706, thereby driving the hollow tube 710 to rise or fall, so that the boosting head 711 is away from or close to the boosting groove 713. Since the fluid has been merged into the three-way intersection, the fluid will flow out through the boosting groove 713. When the boosting head 711 is closer to the boosting groove 713, the enhanced jet effect of the water flow is better; when the boosting head 711 is farther away from the boosting groove 713, the enhanced jet effect of the water flow is weaker.

[0047] See also Figure 7 and Figure 8 The quick release mechanism 9 includes: a first fixed block 901 , a second fixed block 903 , a third fixed block 905 , a first rotating member 907 , and a second rotating member 908 .

[0048] A plurality of first fixing blocks 901 are evenly arranged on the outer circumference of the third pipe 103. A first notch 902 is provided on the surface of the first fixing block 901. A plurality of second fixing blocks 903 are evenly arranged on the outer circumference of the nozzle head 8. A second notch 904 is provided on the surface of the second fixing block 903. A third fixing block 905 is provided on the outer circumference of the third pipe 103. Fig. 9 The third fixed block 905 has two opposite sides fixedly connected with hinge frames 906 , and the two hinge frames 906 are rotatably connected to the first rotating member 907 and the second rotating member 908 respectively.

[0049] The first rotating member 907 and the second rotating member 908 are both arc segment structures. Figures 10 to 12 The first rotating member 907 is provided with an internal through slot 909 at one end away from the articulated frame 906, and a spring 911 is arranged in the internal through slot 909. One end of the spring 911 is fixedly connected to the inner wall of the first rotating member 907, and the other end of the spring 911 is fixedly connected to the second slider 912. The opposite sides of the internal through slot 909 are provided with sliding slots 910 matching the second slider 912, and the second slider 912 slides in the internal through slot 909 through the sliding slots 910. The second slider 912 is fixedly connected with a strip plate 913 at one side away from the spring 911, and the cross section of the strip plate 913 is smaller than the cross section of the internal through slot 909. A clamping rod 914 is fixed to the other end of the strip plate 913, and a handle 915 is arranged on the top of the clamping rod 914. The second rotating member 908 is provided with a clamping slot 916 at one end away from the articulated frame 906, and the clamping slot 916 is adapted to the strip plate 913 and the clamping rod 914.

[0050] In the adaptively adjustable gas-liquid mixing nozzle device of the embodiment, the nozzle head 8 can be quickly disassembled and assembled by the quick-release mechanism 9. When the nozzle head 8 is quickly installed, first hold the handle 915 on the first rotating member and push it toward the internal through groove 909, and the second slider 912 slides along the slide groove 910, so that the strip 913 enters the internal through groove 909, and the spring 911 is in a compressed state. Then, the first rotating member 907 and the second rotating member 908 are rotated to make them snap into the first notch 902 of the first fixed block 901 and the second notch 904 of the second fixed block 903, and then release the handle 915. Due to the elastic force of the spring 911, the strip 913 slides out of the internal through groove 909 and enters the inside of the clamping groove 916, and the clamping rod 914 is clamped into the clamping groove 916. The arc segments of the first rotating member 907 and the second rotating member 908 partially overlap to form an adjustable complete circle, so that the nozzle head 8 is installed and connected with the third pipeline 103. Similarly, when the nozzle head 8 needs to be removed, hold the handle 915 and push it toward the internal groove 909 to allow the strip 913 to re-enter the internal groove 909, then rotate the first rotating member 907 and the second rotating member 908 to keep them away from the first slot 902 and the second slot 904, and the nozzle head 8 can be quickly disassembled.

[0051] The working principle and use process of the self-adaptive gas-liquid mixing nozzle device of this embodiment are as follows:

[0052] First, the first pipe 101 and the second pipe 102 are connected to the external water pump and the air pump respectively, and then the nozzle head 8 is placed in the coal seam to be hydraulically punched, which has been pre-drilled with a drill bit, and the multi-port pipe body 1 is filled with water by the external water pump, and the air pump is used to inflate the interior of the multi-port pipe body 1. The fusion of the internal high-pressure water flow and gas of the multi-port pipe body 1 further enhances the punching efficiency and effectively improves the coal seam crushing effect. At the same time, in this process, the first stepper motor 301 is turned on, and the internal blocking area of ​​the first pipe 101 and the second pipe 102 can be adjusted accordingly through the flow regulating mechanism 3, so as to adjust the flow of water or gas inside the first pipe 101 and the second pipe 102 and complete the initial pressurization.

[0053] When the water flow and gas enter the intersection of the first pipe 101, the second pipe 102 and the third pipe 103, the water flow and gas are fully merged due to the flow direction restriction of the one-way valves 5 on both sides. Then the second stepper motor 701 is turned on, and the water flow and gas in the multi-port pipe body can be enhanced or weakened by the booster mechanism 7 according to the demand. The water flow enters the inside of the nozzle head 8 from the third pipe 103 through the air pressure, and then the nozzle head 8 performs hydraulic punching on the inside of the coal seam to be hydraulically punched.

[0054] When the nozzle head 8 needs to be quickly installed, the quick installation or quick removal of the nozzle head 8 can be completed by operating the quick release mechanism 9, thereby further improving the work efficiency.
