[0029] Embodiment 1

[0030] See also Figure 1 - Figure 6 As shown, the inclinometer for drilling along the layer comprises:

[0031] A standard pipe section 1, wherein an inclinometer is arranged inside the standard pipe section 1;

[0032] An external support assembly, the external support assembly is arranged outside the standard pipe section 1 and is used to support the standard pipe section 1;

[0033] The connecting components are arranged at both ends of the standard pipe section 1 and are used to connect adjacent standard pipe sections 1 .

[0034] From the above, it can be seen that the user can connect multiple standard pipe sections 1 together through the connecting assembly, and then adjust the external support assembly according to the aperture size of the drilled hole. By opening the external support assembly, the standard pipe section 1 can stay at the axial centerline position of the drilled hole, so that the standard pipe section 1 can accurately reflect the inclination angle of the drilled hole when it is tilted.

[0035] The external support assembly includes a first support rod 2 hinged on the outside of the standard pipe section 1, a roller 3 rotatably connected to the end of the first support rod 2, and a second support rod 4 hinged to the end of the first support rod 2. A threaded sleeve 5 is rotatably sleeved on the middle part of the standard pipe section 1, and a threaded ring 8 is threadedly connected to the threaded sleeve 5. The end of the second support rod 4 is hinged to the threaded ring 8.

[0036] As can be seen from the above, when the threaded sleeve 5 rotates, the rotating threaded sleeve 5 forces the threaded ring 8 to move axially on the threaded sleeve 5, and the moving threaded ring 8 drives the second support rod 4 and the first support rod 2 to bend. At this time, the distance between the roller 3 and the standard pipe section 1 becomes larger, and the roller 3 will stick to the inner wall of the in-bedding borehole, thereby making the axial centerline of the standard pipe section 1 fit the axial centerline of the in-bedding borehole, increasing the accuracy of the inclination of the standard pipe section 1 in reflecting the inclination of the in-bedding borehole, and measuring the inclination angle of the borehole through the inclinometer of the standard pipe section 1.

[0037] In order to limit the bending direction of the first support rod 2 and the second support rod 4, the diameter of the roller 3 is larger than the width of the first support rod 2. When the roller 3 is attached to the outer surface of the standard pipe section 1, the first support rod 2 and the second support rod 4 will bend slightly outward. When the first support rod 2 and the second support rod 4 have a bending tendency, the first support rod 2 and the second support rod 4 will bend outward.

[0038] An octagonal column 6 is fixedly connected to the middle of the threaded sleeve 5, and a plurality of insertion holes 7 are arranged in a circular array on the side wall of the octagonal column 6. The user can clamp the octagonal column 6 with a tool to drive the threaded sleeve 5 to rotate, or insert a rod into the insertion hole 7 to drive the threaded sleeve 5 to rotate. The user can select a suitable rotation tool as needed.

[0039] The spiral directions of the threads at both ends of the threaded sleeve 5 are opposite, and a group of external support components are respectively arranged at both ends of the threaded sleeve 5. The first support rod 2, the roller 3, the second support rod 4 and the threaded ring 8 form a support arm, and each group of the external support components includes three groups of support arms. When the threaded sleeve 5 rotates, it can drive the two groups of external support components to open. Since each group of external support components includes three groups of support arms, the three groups of support arms will open at the same time, so that one external support component has three contact points with the inner wall of the borehole, which can effectively increase the installation stability of the standard pipe section 1 and stabilize the standard pipe section 1 at the center position of the borehole.

[0040] The connecting assembly includes a ball head rod 10 threadedly connected to the lower end of the standard pipe joint 1, a chuck 12 sleeved on the ball head rod 10 and a ball sleeve 13 fixedly installed on the upper end of the standard pipe joint 1, the chuck 12 and the ball sleeve 13 cooperate to clamp the ball head rod 10, and the chuck 12 and the ball sleeve 13 are connected by bolts.

[0041] As can be seen from the above, when two standard pipe sections 1 need to be connected together, the ball head rod 10 of the previous standard pipe section 1 can be inserted into the ball sleeve 13 of the next standard pipe section 1, and then the chuck 12 and the ball sleeve 13 are closed to cover the ball head rod 10, and the chuck 12 and the ball sleeve 13 are stably connected together using bolts. At this time, the chuck 12 and the ball sleeve 13 will limit the rotation angle of the ball head rod 10. Since the ball head rod 10 cannot be separated from the chuck 12 and the ball sleeve 13, the two standard pipe sections 1 will be stably connected together. When rotation occurs between the two standard pipe sections 1, the ball head rod 10 will rotate inside the ball sleeve 13, thereby allowing the standard pipe section 1 to accurately reflect the inclination of the drilling hole.

[0042] In order to increase the installation stability of the ball head rod 10, a reinforcing sleeve 9 is fixedly connected to the lower end of the standard pipe section 1. The reinforcing sleeve 9 is sleeved on the outside of the ball head rod 10 to effectively prevent the ball head rod 10 from breaking due to stress during use.

[0043] Embodiment 2

[0045] A standard pipe section 1, wherein an inclinometer is arranged inside the standard pipe section 1;

[0046] An external support assembly, the external support assembly is arranged outside the standard pipe section 1 and is used to support the standard pipe section 1;

[0047] The connecting components are arranged at both ends of the standard pipe section 1 and are used to connect adjacent standard pipe sections 1 .

[0048] From the above, it can be seen that the user can connect multiple standard pipe sections 1 together through the connecting assembly, and then adjust the external support assembly according to the aperture size of the drilled hole. By opening the external support assembly, the standard pipe section 1 can stay at the axial centerline position of the drilled hole, so that the standard pipe section 1 can accurately reflect the inclination angle of the drilled hole when it is tilted.

[0049] The external support assembly includes a first support rod 2 hinged on the outside of the standard pipe section 1, a roller 3 rotatably connected to the end of the first support rod 2, and a second support rod 4 hinged to the end of the first support rod 2. A threaded sleeve 5 is rotatably sleeved on the middle part of the standard pipe section 1, and a threaded ring 8 is threadedly connected to the threaded sleeve 5. The end of the second support rod 4 is hinged to the threaded ring 8.

[0050] From the above, it can be seen that when the threaded sleeve 5 rotates, the rotating threaded sleeve 5 forces the threaded ring 8 to move axially on the threaded sleeve 5, and the moving threaded ring 8 drives the second support rod 4 and the first support rod 2 to bend. At this time, the distance between the roller 3 and the standard pipe section 1 becomes larger, and the roller 3 will stick to the inner wall of the in-layer borehole, thereby making the axial centerline of the standard pipe section 1 fit the axial centerline of the in-layer borehole, increasing the accuracy of the inclination of the standard pipe section 1 to reflect the inclination of the in-layer borehole.

[0051] In order to limit the bending direction of the first support rod 2 and the second support rod 4, the diameter of the roller 3 is larger than the width of the first support rod 2. When the roller 3 is attached to the outer surface of the standard pipe section 1, the first support rod 2 and the second support rod 4 will bend slightly outward. When the first support rod 2 and the second support rod 4 have a bending tendency, the first support rod 2 and the second support rod 4 will bend outward.

[0052] An octagonal column 6 is fixedly connected to the middle of the threaded sleeve 5, and a plurality of insertion holes 7 are arranged in a circular array on the side wall of the octagonal column 6. The user can clamp the octagonal column 6 with a tool to drive the threaded sleeve 5 to rotate, or insert a rod into the insertion hole 7 to drive the threaded sleeve 5 to rotate. The user can select a suitable rotation tool as needed.

[0053] The spiral directions of the threads at both ends of the threaded sleeve 5 are opposite, and a group of external support components are respectively arranged at both ends of the threaded sleeve 5. The first support rod 2, the roller 3, the second support rod 4 and the threaded ring 8 form a support arm, and each group of the external support components includes three groups of support arms. When the threaded sleeve 5 rotates, it can drive the two groups of external support components to open. Since each group of external support components includes three groups of support arms, the three groups of support arms will open at the same time, so that one external support component has three contact points with the inner wall of the borehole, which can effectively increase the installation stability of the standard pipe section 1 and stabilize the standard pipe section 1 at the center position of the borehole.

[0054] The connecting assembly includes a ball head rod 10 threadedly connected to the lower end of the standard pipe joint 1, a chuck 12 sleeved on the ball head rod 10 and a ball sleeve 13 fixedly installed on the upper end of the standard pipe joint 1, the chuck 12 and the ball sleeve 13 cooperate to clamp the ball head rod 10, and the chuck 12 and the ball sleeve 13 are connected by bolts.

[0055] As can be seen from the above, when two standard pipe sections 1 need to be connected together, the ball head rod 10 of the previous standard pipe section 1 can be inserted into the ball sleeve 13 of the next standard pipe section 1, and then the chuck 12 and the ball sleeve 13 are closed to cover the ball head rod 10, and the chuck 12 and the ball sleeve 13 are stably connected together using bolts. At this time, the chuck 12 and the ball sleeve 13 will limit the rotation angle of the ball head rod 10. Since the ball head rod 10 cannot be separated from the chuck 12 and the ball sleeve 13, the two standard pipe sections 1 will be stably connected together. When rotation occurs between the two standard pipe sections 1, the ball head rod 10 will rotate inside the ball sleeve 13, thereby allowing the standard pipe section 1 to accurately reflect the inclination of the drilling hole.

[0056] In order to increase the installation stability of the ball head rod 10, a reinforcing sleeve 9 is fixedly connected to the lower end of the standard pipe section 1. The reinforcing sleeve 9 is sleeved on the outside of the ball head rod 10 to effectively prevent the ball head rod 10 from breaking due to stress during use.

[0057] The ball head rod 10 has a plurality of balls 11 clamped on the outside, and the balls 11 abut against the inner walls of the chuck 12 and the ball sleeve 13. When the ball head rod 10 rotates inside the ball sleeve 13, the balls 11 will adhere to the inner walls of the chuck 12 and the ball sleeve 13 and rotate, thereby effectively reducing the friction between the ball head rod 10 and the ball sleeve 13 and increasing the rotation flexibility of the ball head rod 10.
