As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, an embodiment of the utility model provides a drilling anti-deviation device: it includes an external shell 1, the outer wall of the external shell 1 is fixedly connected to a shell 2, a support rod 3 is hinged in the shell 2, the end of the support rod 3 away from the shell 2 is fixedly connected to a shell 3 9, the outer side of the shell 3 9 is fixedly connected to a connecting rod 4 and a connecting rod 2 5, the outer wall of the connecting rod 25 is hinged to a shell 2 6, one side of the shell 2 6 is fixedly connected to a support plate 7, the upper surface of the support plate 7 is fixedly connected to a spring 8, the end of the spring 8 away from the support plate 7 is fixedly connected to a support block 20, the support block 20 is fixedly connected to the support rod 3, the outer wall of the connecting rod 4 is hinged to an electric hydraulic rod 10, and the electric hydraulic rod 10 is hinged to the outer wall of the external shell 1.

[0027] In one embodiment, a support rod 2 11 is fixedly connected to the inner wall of the external shell 1, and a limit tube 12 is hinged on the outer wall of the support rod 2 11. The limit tube 12 is located inside the external shell 1, and the outer wall of the limit tube 12 is fixedly connected to a limit block 13. A connecting rod 3 14 is arranged on the upper and lower sides of the limit block 13, and one end of the connecting rod 3 14 is fixedly connected to a threaded rod 15, and the other end of the connecting rod 3 14 is fixedly connected to a threaded rod 2 16. The threaded directions of the threaded rod 15 and the threaded rod 2 16 are opposite, and the threaded rod 15 and the threaded rod 2 16 are respectively rotatably connected to the external shell 1, and the outer walls of the threaded rod 15 and the threaded rod 2 16 are threadedly connected to a limit block 2 18, and the two limit blocks 2 18 are located on both sides of the limit block 13, and one end of the threaded rod 2 16 is fixedly connected to a handle 17, and the handle 17 is located outside the external shell 1.

[0028] In one embodiment, two groups of housing 1 2, support rod 1 3 and electric hydraulic rod 10 are provided, and the two groups of housing 1 2, support rod 1 3 and electric hydraulic rod 10 are located on both sides of the outer housing 1. The two groups of housing 1 2, support rod 1 3 and electric hydraulic rod 10 support the outer housing 1 more stably. Universal wheels 19 are fixedly connected to the lower surface of the outer housing 1, and the number of universal wheels 19 is multiple. Multiple universal wheels 19 facilitate the staff to move the outer housing 1. The shape of housing 3 9 is a triangle, and connecting rod 1 4 and connecting rod 2 5 are located at the two corners of the triangle. There are two groups of limit blocks 13, connecting rod 3 14 and handles 17, and the two groups of limit blocks 13, connecting rod 3 14 and handles 17 are located on both sides of the limit tube 12. The two groups of connecting rod 3 14 and handles 17 clamp the limit blocks 13 together to ensure the stability of the limit tube 12.

[0029] When the utility model is working: with the cooperation of the universal wheel 19, after the drilling anti-deviation device is moved to a suitable position, the electric hydraulic rod 10 is started, and the electric hydraulic rod 10 is extended to drive the connecting rod 4 to move. Since the electric hydraulic rod 10 is hinged to the external shell 1, the connecting rod 4 swings downward. Since the connecting rod 4 is fixedly connected to the shell 3 9 and the support rod 3 and the support rod 3 is hinged to the shell 2, the support rod 3 drives the shell 3 9 to swing downward around the shell 2. When the bottom of the support plate 7 contacts the ground, with the cooperation of the spring 8, the support plate 7 swings around the connecting rod 2 5 until it is completely in contact with the ground, so that it is not affected by the ground state, and the external shell 1 is quickly supported to prevent the universal wheel 19 from moving during drilling, causing the drill bit to deviate from the predetermined Drilling trajectory; when the ground is uneven and causes the outer shell 1 to be skewed as a whole, the staff turns the handle 17, and the rotation of the handle 17 drives the connecting rod three 14, the threaded rod one 15 and the threaded rod two 16 to rotate. Since the connecting rod three 14 is arranged on the upper and lower parts of the limit block 13, the two groups of connecting rod three 14, the threaded rod one 15 and the threaded rod two 16 cooperate with each other, so that the limit block two 18 located on both sides of the limit block one 13 moves away from the limit block one 13 on the outer walls of the threaded rod one 15 and the threaded rod two 16. At this time, with the cooperation of the support rod two 11, the limit tube 12 naturally droops, and the limit tube 12 is vertical. The handle 17 is reversed, and the limit tube 12 is fixed by fixing the limit block one 13 to ensure that the limit tube 12 is vertical, thereby preventing drilling deviation and affecting the exploration results.

Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
