[0002] The explosion-proof submersible sand pump for mining is an efficient and safe drainage equipment designed specifically for heavy industrial fields such as mining. It has explosion-proof and corrosion-resistant properties, a compact structure, small size, light weight, and is easy to transport and install. At the same time, the motor runs submerged in water, requiring no additional cooling system, which is beneficial to environmental protection.
[0003] At present, mining explosion-proof submersible sand-draining electric pumps need to operate in water, which makes them susceptible to erosion by sand and other substances in the water, leading to damage.

Moreover, when working in water for a long time, the entire shell is soaked in water, and the quicksand washes away the external shell, causing damage or the screws and nuts to fall off.

The lower side of the electric pump 1 is fixedly connected with a sand filter net 2, the upper side of the electric pump 1 is fixedly connected with a pipe mouth 3, and the outer side of the pipe mouth 3 is fixedly connected with a rubber ring 29. The ring 29 has good sealing performance to prevent water leakage from the pipe mouth 3. The upper side of the electric pump 1 is fixedly connected to the terminal block 4; the sealing structure includes a support plate 5 fixedly connected to the side wall of the electric pump 1, the side wall of the support plate 5 is rotatably connected to the rotating rod 6, the outer side of the rotating rod 6 is fixedly connected to the rocker 7, the outer side of the rotating rod 6 is fixedly connected to the spur gear 1 8, the side wall of the support plate 5 is slidably connected to the slide plate 1 9 and the slide plate 2 10, the side wall of the slide plate 1 9 is fixedly connected to the spur rack 1 11, the side wall of the slide plate 2 10 is fixedly connected to the spur rack 2 12, the spur rack 11 and the spur rack 2 12 are meshed with the spur gear 1 8, and the side wall of the slide plate 1 9 is fixed. It is connected to an upper splint 13, and the side wall of the slide plate 2 10 is fixedly connected to the lower splint 14. The side wall of the upper splint 13 is fixedly connected to a connecting plate 15, and the side wall of the connecting plate 15 is fixedly connected to a baffle 16. The side wall of the lower splint 14 is slidably connected to a top block 17, and the side wall of the lower splint 14 is slidably connected to a baffle 18. The baffle 18 runs through the top block 17. A rapping structure is installed on the support plate 5, and the rapping structure includes a spur gear 2 19 fixedly sleeved on the outside of the rotating rod 6. The side wall of the support plate 5 is rotatably connected to a plurality of rotating shafts 20, and a plurality of spur gears 3 21 are fixedly connected to the outside of the rotating shafts 20, and the plurality of spur gears 3 21 are rotatably connected to the side wall of the support plate 5. They are meshed with each other, one of the spur gears 3 21 is meshed with the spur gear 2 19, one of the rotating shafts 20 is fixedly connected to the outside of the rotating shaft 20 with a turntable 22, the side wall of the turntable 22 is fixedly connected to a spherical slider 23, the outside of the rotating shaft 20 is sleeved with a slider 24, the slider 24 is only sleeved on the outside of the rotating shaft 20, and there is no other connection relationship between the rotating shaft 20, that is, the rotating shaft 20 cannot drive the slider 24 to rotate relative to the rotating shaft 20 and move along the direction of the rotating shaft 20, the side wall of the slider 24 is fixedly connected to a vibration block 25, and a spring 26 is fixedly connected between the slider 24 and the rotating shaft 20.
[0024] When the work is complete, the staff can rotate the electric pump 1 to rotate the external water pipe 3 and connect the external water pipe to the nozzle 3 through the screw and nut. At this time, the staff can rotate the rocker 7 to drive the rocker 7 to rotate. The rocker 7 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the slide plate 19 to move through the spur gear 18 and the spur rack 11. The movement of the slide plate 19 drives the upper clamping plate 13 to move downward. At the same time, the rotating rod 6 also drives the slide plate 2 10 to move through the spur gear 18 and the spur rack 2 12. The slide plate 10 drives the lower clamping plate 14 to move upward. The relative movement of the upper clamping plate 13 and the lower clamping plate 14 clamps and seals the nozzle 3. During the upward movement of the lower clamping plate 14, the baffle 16 is pushed upward by the arc surface of the top block 17. Because the baffle 16 can only rotate upward, when the top block 17 moves to the corresponding position, the baffle 16 returns to its original position, thereby blocking the top block 17, so that the clamping and sealing effect is better. When work is not needed, the baffle 18 can be lifted so that the top block 17 can be The upper and lower clamping plates 13 and 14 can be separated from each other by shaking the rocker 7. The sealing structure prevents the nozzle 3 from collapsing due to excessive pressure, and also avoids the erosion of materials such as sand in the water, which leads to the instability of the screw and nut. The blocking of the two clamping plates can prevent the erosion of most quicksand. While sealing, the rotating rod 6 drives the rotating shaft 20 to rotate through the spur gear 2 19 and the spur gear 3 21, and the rotating shaft 20 drives the turntable 22 to rotate. The rotation of the turntable 22 drives and rotates the spherical slider 23 on the outside, and then squeezes the slider 24 through the arc surface of the spherical slider 23. The slider 24 rebounds through the spring 26 to complete the vibration work. The vibration of the slider 24 drives the vibration block 25 to vibrate the outer shell of the electric pump 1 to check whether there is any screw falling off the outer shell, to prevent the outer shell from loosening due to long-term muddy water scouring, thereby causing the screw and nut to loosen, and avoid falling during the work process to affect the work progress.
