Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Combined with Figure 1-5 In this embodiment, a downhole water exploration and discharge device includes: a pipeline 1, a drainage pipe 11 is fixedly installed on one side of the bottom of the pipeline 1, and a sealing ring 12 is fixedly installed in the middle of one side of the pipeline 1, and the sealing ring 12 is annular in shape.

[0026] A support ring 13 is fixedly installed at one edge of the outer side of the pipe 1, and the support ring 13 is in an annular shape.

[0027] Four mounting grooves 14 are fixedly mounted around one side of the support ring 13 , and screw pins 15 are movably connected inside the mounting grooves 14 .

[0028] Specifically, the mud and water inside the pipe 1 are discharged through the drain pipe 11 and supported by the support ring 13 . The pipe 1 can be fixed at a designated position by the threaded nail 15 movably connected inside the mounting groove 14 .

[0029] A drainage trough 2 is fixedly installed at the bottom of the drainage pipe 11, and a supporting trough 21 is fixedly installed at the bottom of the drainage trough 2. The supporting trough 21 is in the shape of a "mouth". Four supporting blocks 22 are fixedly installed around the inner bottom of the supporting trough 21. The supporting blocks 22 are in the shape of a triangle. A diverter plate 23 is fixedly installed on the top of the supporting blocks 22. The diverter plate 23 is in the shape of a grid. A top plate 24 is fixedly installed on the outer bottom of the supporting trough 21. The top plate 24 is in the shape of a "mouth".

[0030] Specifically, the high-pressure sprayed water can be intercepted by the diverter plate 23, and the pressure of the high-pressure sprayed water can be reduced by passing through the hole in the middle of the diverter plate 23. The support groove 21 is supported by the support block 22. The holes in the support groove 21 are relatively large to allow gravel and mud to pass through. Since the diameter of the support groove 21 is larger than the diameter of the drain pipe 11, a pressure reduction effect can be formed.

[0031] A water tank 3 is fixedly installed at the bottom of the top plate 24, two sliding grooves 31 are fixedly installed on both sides of the inner top of the water tank 3, a rotating plate 32 is fixedly installed on one side of the sliding groove 31, a filter screen 33 is fixedly installed in the middle of the inner part of the water tank 3, a collecting groove 34 is fixedly installed on the top of one side of the water tank 3, a collecting box 35 is movably connected inside the collecting groove 34, an intercepting net 36 is fixedly installed on one side of the bottom of the collecting box 35, and a water pump 37 is fixedly installed on the bottom of one side of the water tank 3.

[0032] Specifically, the sprayed water can be filtered through the filter net 33, and the silt above the filter net 33 can be scraped into the collection box 35 inside the collection tank 34 through the sliding of the rotating plate 32 inside the sliding groove 31 and the rotation of the rotating plate 32. The water inside the collection box 35 can be discharged through the intercepting net 36, and the silt can be cleaned by taking out the collection box 35.

[0033] A drill rod 4 is movably connected inside the pipe 1 , and a connecting rod 41 is fixedly installed on one side of the drill rod 4 .

[0034] A rotator 42 is fixedly mounted on one side of the connecting rod 41 .

[0035] A support frame 43 is fixedly mounted on the outer side of the rotator 42 .

[0036] Specifically, the rotator 42 is supported by the support frame 43, and the rotation of the rotator 42 can drive the connecting rod 41 and the drill rod 4 to rotate, so that drilling can be performed, thereby improving the stability of the downhole water exploration and release equipment.

[0037] Working principle: First, support is provided through the sealing ring 12, and the support ring 13 can be fixed at the specified position through the threaded nail 15 inside the mounting groove 14, so as to fix the pipe 1, and the rotator 42 is supported and fixed by the support frame 43. The operation of the rotator 42 can drive the connecting rod 41 and the drill rod 4 to rotate, so as to drill a hole, and the sealing ring 12 inside one side of the pipe 1 can fit the connecting rod 41 for sealing, thereby avoiding leakage problems, and the sediment water entering the pipe 1 is discharged through the drain pipe 11 at the bottom of the pipe 1, and the sediment water discharged from the drain pipe 11 is sent into the support groove 21 through the drain groove 2, and the ejected sediment water can be pressure-relieved through the diverter plate 23 inside the support groove 21. Since the diameter of the support groove 21 is larger than the drain pipe 11, it can achieve a pressure relief effect, and the diverter plate 23 can slow down the sediment water. The flow rate is improved by the larger hole in the middle of the diverter plate 23, so that the silt can pass through without clogging, thereby improving the practicability of the downhole water exploration and release equipment. The diverter plate 23 can be auxiliary supported by the support block 22, thereby improving the stability and supporting force of the downhole water exploration and release equipment. The silt water entering the water storage tank 3 can be filtered through the filter screen 33, and the silt in the water can be filtered out. The rotating plate 32 can slide back and forth inside the two sliding grooves 31, and the silt above the filter screen 33 can be scraped into the collection box 35 inside the collection groove 34 through the rotation of the rotating plate 32. The water inside the collection box 35 can be filtered out and sent to the inside of the water storage tank 3 through the interception net 36 on one side of the bottom of the collection box 35. The filtered silt can be cleaned by taking out the collection box 35, thereby improving the practicability of the downhole water exploration and release equipment. The water can be pumped out by the water pump 37.
