[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: a drilling inclination measurement and deviation prevention device, including a sleeve 2 and a drill pipe 1. The drill pipe 1 reciprocates up and down inside the sleeve 2. It further includes: a deviation alarm device, which is arranged on the sleeve 2. The deviation alarm device is arranged to match the outer side wall of the drill pipe 1, and can control the deviation angle of the drill pipe 1 within the deviation range through the deviation alarm device. Moreover, the deviation alarm device can be rotationally adjusted to the distance from the outer side wall of the drill pipe 1; when the drill pipe 1 moves up and down inside the sleeve 2, the deviation alarm device arranged inside the sleeve 2 can match the drill pipe 1. Through the deviation alarm device, the deviation position and azimuth of the drill pipe 1 can be quickly measured. After being alarmed by the deviation alarm device, rotate the deviation alarm device to adjust the distance from the drill pipe 1, so that the deviation azimuth of the drill pipe 1 can be adjusted, and the drill pipe 1 can be prevented from deviating out of the reasonable range.

[0021] As Figure 4 shown, the deviation alarm device includes: a fixed rod 3, which is fixedly connected to the inner wall of the sleeve 2. A guide rod 4 is slidably connected to the lower end of the fixed rod 3. A fixed plate 5 is fixedly connected to the inner end of the guide rod 4. A guide wheel 6 is rotatably connected to the fixed plate 5. The guide wheel 6 is arranged to roll on the outer side wall of the drill pipe 1; an adjusting rod 8, which is threadedly connected to the sleeve 2. An induction trigger 9 is arranged inside the adjusting rod 8. An alarm lamp 10 is fixedly connected to the outer end of the induction trigger 9. And the position of the induction trigger 9 corresponds to the position of the guide rod 4. The guide rod 4 can be restricted on the fixed rod 3 through the fixed rod 3. A fixed plate 5 is fixed to the inner end of the guide rod 4. A guide wheel 6 is rotatably connected to the fixed plate 5. When the drill pipe 1 reciprocates up and down, the deviation azimuth is measured through the guide wheel 6. The guide wheels 6 are distributed in four azimuths of the drill pipe 1, and each is independently slidable. Thus, when the drill pipe 1 deviates in any azimuth, the induction trigger 9 can be triggered, and then the operator can be informed through the alarm lamp 10 on the outside. Then, the adjusting rod 8 at the position of the alarm lamp 10 can be rotationally adjusted in time; the induction trigger 9 is a prior art. By being triggered by impact, the alarm lamp 10 can be made to emit light, and thus the triggering effect can be obtained. Therefore, the induction trigger 9 is not described in detail here.

[0022] As Figure 4As shown in the figure, the deviation alarm device further includes a scraping plate 7. The scraping plate 7 is fixedly connected to the lower end of the fixing plate 5. The lower end of the scraping plate 7 is inclined, and the upper end of the scraping plate 7 is also inclined. Both the upper end and the lower end of the scraping plate 7 are in sliding contact with the outer side wall of the drill pipe 1. The arc of the scraping plate 7 is set as a quarter circle. When the drill pipe 1 moves up and down, the soil on the surface of the drill pipe 1 can be shoveled off by the scraping plate 7 to prevent the soil from affecting the triggering of the induction trigger 9. And when the drill pipe 1 moves downward, the muddy water on the surface of the drill pipe 1 can be scraped off again by the inclination of the upper end of the scraping plate 7, so that the induction trigger 9 can always maintain the induction sensitivity.

[0023] As Figure 4 shown in the figure, a fixing ring 14 is threadedly connected to the outer side wall of the guide rod 4. A folding cover 13 is fixedly connected to the outer side wall of the fixing ring 14. The folding cover 13 extends to be arranged on the adjusting rod 8. The inner end of the adjusting rod 8 is fixedly connected with a spring 12. The other end of the spring 12 abuts against the fixing ring 14. When the drill pipe 1 generates deviation, the impact force of the deviation can be reduced by the spring 12. And a folding cover 13 is fixed on the outer side wall of the fixing ring 14. The spring 12 and the triggering end of the induction trigger 9 can be protected by the folding cover 13.

[0024] As Figure 4 shown in the figure, a nut 11 is fixedly connected to the outer end of the adjusting rod 8. The nut 11 on the outer side of the adjusting rod 8 can be rotated by a wrench, which is convenient for rotating the adjusting rod 8, and thus the operation is convenient and fast.

[0025] As Figure 4 shown in the figure, the alarm lamp 10 is set to be red. The red color of the alarm lamp 10 is more conspicuous on the construction site, and thus it is convenient for the operator to make a quick response.

[0026] As Figure 4 shown in the figure, the guide wheels 6 are symmetrically distributed up and down on the fixing plate 5. The symmetrical arrangement of the guide wheels 6 up and down can make the matching between the drill pipe 1 and the guide wheels 6 more stable.

[0027] The above is only the preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments with equivalent changes, but as long as it does not depart from the technical content of the present invention, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
