[0028] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0029] like Figures 1-6 As shown, the integrated upper and lower hole sweeping device provided in this embodiment includes a hollow water guide pipe 1 with an opening at the top. A first variable diameter pipe 2 is provided on the outer wall of the middle part of the water guide pipe 1. Two second variable diameter pipes 3 are symmetrically arranged on the outer wall of the first variable diameter pipe 2. Multiple spray holes 4 communicating with the water guide pipe 1 are provided on the side of the two second variable diameter pipes 3 that are far apart from each other. A rolling mechanism located between the two second variable diameter pipes 3 is fixedly installed on the outer wall of the first variable diameter pipe 2. The rolling mechanism includes an annular frame 5 installed on the outer wall of the first variable diameter pipe 2. Multiple circumferentially distributed pressure rollers 6 are rotatably installed on the outer side of the annular frame 5. By setting a first variable diameter pipe 2 and a second variable diameter pipe 3 on the outer wall of the water guide pipe 1, the device initially sweeps the holes through multi-stage variable diameter during the rotation and descent process. Through the setting of the spray hole 4, the high-pressure water in the water guide pipe 1 forms a jet through the spray hole 4. During the rotation and descent process, the high-pressure water flow further sweeps the holes, thereby reducing the wear on the cutter head and improving the sweeping efficiency. Through the setting of the compaction mechanism, the pressure roller 6 can compact the inner wall of the well barrel.

[0030] In an optional embodiment, the inlet pipe of the water guide pipe 1 is fixedly connected to a connector 7. The connector 7 has a bayonet 701 on its outer wall and an internal thread 702 on its inner side. The connector 7 allows it to be connected to a drilling mechanism.

[0031] In an optional embodiment, the bottom end of the water guide pipe 1 is provided with a first chamfer 8, both the upper and lower ends of the first reducing pipe 2 are provided with second chamfers 9, and the ends of the two second reducing pipes 3 that are far apart from each other are provided with third chamfers 10. The nozzle 4 is opened on the third chamfer 10. The setting of the first chamfer 8, the second chamfer 9 and the third chamfer 10 reduces the resistance encountered when sweeping the hole. The nozzle 4 is opened on the third chamfer 10 so that the water flow sprayed from the nozzle 4 forms an acute angle with the water guide pipe 1.

[0032] In an optional embodiment, the annular frame 5 includes two semi-annular frames 11 connected by bolts. Each semi-annular frame 11 includes an arc-shaped plate 111, with end plates 112 fixedly connected to both the upper and lower ends of the arc-shaped plate 111. The end plates 112 have rotating holes 113 that rotatably engage with the pressure roller 6. Connecting plates 114 are fixedly connected to both sides of the arc-shaped plate 111, and the connecting plates 114 have mounting holes 115. Multiple locking blocks 12 are evenly arranged on the outer wall of the first reducing pipe 2, and the arc-shaped plate 111 has locking grooves 116 that engage with the locking blocks 12. Through the arrangement of the semi-annular frames 11, the annular frame 5 and the first reducing pipe 2 can be detachably connected. In use, the locking blocks 12 are inserted into the locking grooves 116, and then the two semi-annular frames 11 are fixed with bolts.

[0033] In this embodiment, as Figures 1-6 As shown, the working process of the integrated upper and lower hole-scanning device provided in this embodiment is as follows:

[0034] In use, the water guide pipe 1 is connected to the drilling mechanism and the high-pressure water pump. During the rotation and descent, the hole is initially swept through the multi-stage variable diameter. Through the setting of the nozzle 4, the high-pressure water in the water guide pipe 1 forms a jet through the nozzle 4. During the rotation and descent, the hole is further swept through the high-pressure water flow, thereby reducing the wear on the cutter head and improving the sweeping efficiency. Through the setting of the compaction mechanism, the pressure roller 6 can compact the inner wall of the well barrel.

[0035] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
