[0035] The first driving rod 7 is rotatably connected to the well pipe 1 through the second bearing seat 8. The first driving rod 7 is transmission-connected to the guide rod 4. The first driving rod 7 is transmission-connected to a rotating ring 10. The rotating ring 10 is rotationally connected to the well pipe 1 through the third bearing seat 11. A pair of connecting rods 12 are fixedly connected to the rotating ring 10. A plurality of cleaning mechanisms are fixedly connected between the pair of connecting rods 12. The cleaning mechanisms correspond to and offset the plurality of penetration sections 2 one by one.

[0036] By inserting the well pipe 1 into the wellbore, the brine is infiltrated into the well pipe 1 by the penetration section 2, and the pump pipe 3 is connected to the pump to collect the brine out of the well pipe 1. During the collection process, since the collection end of the pump pipe 3 is close to the bottom end of the well pipe 1, the brine in the well pipe 1 flows from top to bottom when the brine is absorbed, and is absorbed upward at the collection end of the pump pipe 3, so that the brine pushes the first guide blade 6 below the collection end of the pump pipe 3, so that the first guide blade 6 is driven by the force to drive the guide rod 4 to rotate, and then the guide rod 4 drives the first driving rod 7 to rotate, so that the first driving rod 7 drives the rotating ring 10 and a pair of connecting rods 12 fixedly connected to the rotating ring 10 to rotate, so that the multiple cleaning mechanisms between the pair of connecting rods 12 can rotate along the annular penetration section 2, so as to achieve the effect of automatically cleaning the penetration section 2, avoid blockage of the penetration section 2, so that the penetration section 2 maintains a good flow efficiency, so that the brine collection remains in a high efficiency state, and the service life of the device is improved.

[0037] According to a further optimized solution, a first bevel gear 13 is fixedly connected to the guide rod 4 , a second bevel gear 14 is meshed with the first bevel gear 13 , and the second bevel gear 14 is fixedly connected to the first driving rod 7 .

[0039] According to a further optimized solution, a first spur gear 15 is fixedly connected to the first driving rod 7 , a first spur gear ring 16 is meshed with the first spur gear 15 , and the first spur gear ring 16 is fixedly connected to the rotating ring 10 .

[0040] When the first driving rod 7 rotates, the first spur gear 15 drives the first spur ring gear 16 to rotate, and the first spur ring gear 16 drives the rotating ring 10 to rotate.

[0041] According to a further optimized solution, the cleaning mechanism includes a mounting frame 17 , which is fixedly connected to a pair of connecting rods 12 , and a pair of scrapers 18 are slidably connected to the mounting frame 17 , and the pair of scrapers 18 abut against the infiltration section 2 .

[0042] The mounting frame 17 is driven to rotate along the penetration section 2 by a pair of connecting rods 12 , so that the penetration section 2 is cleaned by a pair of scrapers 18 .

[0043] Further optimization scheme, a pair of guide rods 19 are fixedly connected in the mounting frame 17, a guide ring 20 is slidably sleeved on the guide rod 19, the pair of guide rings 20 correspond to the pair of scrapers 18 one by one and are fixedly connected, a spring 21 is fixedly connected between the guide ring 20 and the mounting frame 17, a lever 22 is fixedly connected to the guide ring 20, a cam 23 is abutted between the pair of levers 22, the cam 23 is rotatably connected to the mounting frame 17, and the cam 23 is transmission-connected to the driving mechanism. The driving mechanism includes a second driving rod 24, the second driving rod 24 is rotatably connected to the rotating ring 10 through a fourth bearing seat 25, a second spur gear 26 is fixedly connected to the second driving rod 24, the second spur gear 26 is meshed with a second spur gear ring 27, the second spur gear ring 27 is fixedly connected to the well pipe 1, and the second driving rod 24 is transmission-connected to multiple cams 23. A plurality of third bevel gears 28 are fixedly connected to the second driving rod 24, and the third bevel gears 28 are meshed with fourth bevel gears 29, and the plurality of fourth bevel gears 29 correspond to and are fixedly connected to the plurality of cams 23. A pair of guide grooves 30 are provided on the mounting frame 17, and the pair of levers 22 are slidably fitted in the pair of guide grooves 30 one by one.

[0044] When the mounting frame 17 rotates along the infiltration section 2, the rotating ring 10 drives the second driving rod 24 to move, so that the second spur gear 26 on the second driving rod 24 rotates along the second spur gear ring 27, and then the second driving rod 24 is rotated through the meshing effect of the second spur gear 26 and the second spur gear ring 27, and then the third bevel gear 28 on the second driving rod 24 drives the fourth bevel gear 29 to rotate, so that the cam 23 rotates, and then the cam 23 pushes a pair of levers 22 to move away from each other along the guide groove 30, and the lever 22 drives the guide ring 20 and the scraper 18 to move along the guide rod 19, so that the pair of scrapers 18 move away from each other and are automatically reset by the spring 21. In this way, the cam 23 continues to rotate, which can make the reciprocating scraping effect of the pair of scrapers 18, and the pair of scrapers 18 move away from each other, which can increase the cleaning area and improve the cleaning effect.

[0047] According to a further optimization scheme, the infiltration section 2 is a filter structure. The infiltration section 2 of the annular filter structure can improve the infiltration effect of the brine and cooperate with the rotatable cleaning structure to improve the brine collection efficiency of the brine collection device.

[0048] Furthermore, a rotary drilling rig is used to construct a brine well. The equipment selected is JCR-3208 rotary drilling rig, the drilling depth is 25-35 meters, the opening diameter is φ1600mm, the final hole diameter is φ1600mm, the wellbore diameter is φ1200mm, and a tray kelp waterstop is used. The outer diameter of the tray is 1500mm, the well wall pipe thickness is 10mm, waterstop kelp, 14# iron wire and other auxiliary materials are used. Kelp with thick flesh, wide leaves and long body is selected. After being soaked in fresh water, it is braided into a dense kelp braid and wrapped around the outside of the well pipe 1, 0.5 meters below the waterstop tray. The thickness of the kelp braid is 30cm, and it is tied and bound with iron wire. The diameter of the well pipe 1 is φ1200mm and the thickness is 10mm. The top of the well pipe 1 should not be less than 0.5m above the ground.

[0049] After the pipe is lowered, the wellhead cementing plate is welded. The main material of the cementing plate is ordinary steel plate: about 10mm thick, specification: 1.5*6m. Angle steel: 80*80mm. The cementing plate is 2.5*2.5m long and wide, divided into two pieces, with a circular hole of φ1200mm in the middle.

[0050] Furthermore, an air compressor is used for well washing. Method 1: When the vibration well washing method is used, the mixer is lowered to the middle and lower part of the well pipe 1, and a dedicated person controls the air supply valve. When the air pressure is held to the rated maximum value, the air supply valve is suddenly opened to allow the compressed air to effectively vibrate and wash the well in the well pipe 1 at the maximum speed and maximum pressure. The pressure is held once every 5-10 minutes until the well is washed. Method 2: When using an air compressor to discharge slag and wash the well, the outlet pipe should be lowered to the bottom of the well pipe 1, the air pipe sinking ratio should not be less than 50%, and water should be pumped to wash the well with the maximum depth and the maximum water volume to achieve water-clear sand.

[0051] Furthermore, after the well is flushed, a brine pumping test is carried out on the well, and the stabilization time for the depth reduction is 2-4 hours. The water level and flow rate observation frequency of the brine pumping test is 5, 10, 15, 20, 25, and 30 minutes after the start of the pumping test, and then every 30 minutes.
