[0002] Coal is one of the important primary energy sources in my country. It has strongly supported the development of my country's national economy and the progress of science and technology. At present, the main coal mining methods include underground mining and open-pit mining, among which underground mining occupies the main position. However, in the process of underground mining, accidents such as rock burst, coal and gas outburst, water seepage, and coal-rock gas compound dynamic disasters often occur. Therefore, corresponding measures need to be taken in the mining process for prevention and control. Among them, drilling pressure relief, drilling extraction, drilling water exploration and deep hole blasting are all the current mainstream means, but the first prerequisite for the above measures is to drill a suitable hole.

[0003] At present, most of the existing drilling equipment can only achieve straight line drilling. When encountering tricky drilling positions, it may be necessary to change the drilling angle and direction to solve the problem. However, it is difficult to achieve this with current equipment and means. It is difficult to achieve the effect of precise drilling in the actual construction process, and the performance is not ideal. The main reason is that the angle of the drill bit cannot be controlled.

[0004] Therefore, it is necessary to provide a directional drilling device with a rotatable angle and a method of using the same to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a directional drilling device with a rotatable angle and a method of using the same, so as to solve the technical problems existing in the prior art.

10. A method for using a directional drilling device capable of rotating an angle, characterized in that: The method is applied to the directional drilling equipment with a rotatable angle as described in any of claims 1 to 9 above, and the method comprises the following steps: S1. Place the fixed base (1) of the drilling equipment on the flat ground of the area to be drilled, turn on the main switch (21) of the equipment, and start the motor (2); S2, perform straight-line drilling, turn on the switch (22) for controlling the magnetic ball of the main drill barrel, and then the magnetic ball (5) of the main drill barrel generates current, thereby generating magnetism. Under the attraction of the ball joint connecting rod (20) on the magnetic ball joint device (4), the spring (6) inside the main drill barrel is rapidly stretched, so that the magnetic balls (5) of the main drill barrels on the left and right sides are connected to the magnetic ball joint device (4), and then the motor (2) provides power, the ball joint roller (19) in the magnetic ball joint device (4) rotates rapidly, and the ball joint connecting rod (20) welded thereto rotates, and the magnetic balls (5) of the main drill barrels on the left and right sides generate rotational power, driving the main drill barrel to rotate; at this time, the left hydraulic rod (12) and the right hydraulic rod (13) of the drill bit (10) are partially fully retracted; S3. When the straight drilling reaches a predetermined distance and needs to change direction, the main drill barrel control magnetic ball power switch (21) is turned off. At this time, the left and right main drill barrel control magnetic balls (5) are disconnected from the magnetic ball hinge device (4), and the main drill barrel loses power and stops rotating. Then, the primary hydraulic rod (9) is extended upward through the operation of the primary hydraulic control rod (23) until it reaches the drill head control magnetic ball position (15); S4, simultaneously turning on the drill bit control magnetic ball power switch (24) to make it magnetic, attracting the magnetic ball (14) attached to the primary hydraulic rod and magnetically connecting with it, so that the drill bit (10) obtains power and can realize rotary drilling; S5, opening the left hydraulic control rod (25) and the right hydraulic control rod (26) of the drill bit, and extending and retracting the left and right hydraulic rods of the drill bit up and down according to the geological structure and the required adjustment angle to change the angle of the entire drill bit (10), and at the same time using the primary hydraulic control rod (23) to adjust the telescopic length and left and right angle of the primary hydraulic rod (9) to make it match the adjustment position of the drill bit (9) as much as possible, and further perform variable angle drilling; S6. After the drilling is completed, first adjust the left and right hydraulic rods of the drill bit to retract the part of the drill bit (10) that has been deflected, and make it completely retracted to its original state before it was started, and then turn off the main switch of the equipment (20), retract the drilling equipment, and clean up the equipment and the site.
