[0002] Coal is one of my country's important primary energy sources, strongly supporting the development of the national economy and the advancement of science and technology. Currently, the main coal mining methods include underground mining and open-pit mining, with underground mining occupying the dominant position. However, underground mining often causes accidents such as rock burst, coal and gas outbursts, water seepage, and coal-rock gas combined dynamic disasters. Therefore, corresponding measures must be taken during the mining process to prevent and control them. Among them, drilling pressure relief, drilling extraction, drilling water exploration, and deep-hole blasting are all currently the mainstream methods. However, the primary prerequisite for implementing these 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, the current equipment and means are difficult to achieve. It is difficult to achieve the effect of precise drilling during actual construction, 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 present invention aims to provide a directional drilling device with a rotatable angle and its use method to address the technical problems existing in the prior art. Specifically, through an improved design of the internal device of the drilling rig, the operator can control the angle of the drill bit by simply pressing a button, thereby achieving directional drilling.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a directional drilling device with a rotatable angle, which includes five parts: a fixed base, a power unit, a linear drilling mechanism, a variable angle drilling mechanism and an operation control box. The fixed base is a stable foundation for the entire device, which is used to firmly position the drilling device on the ground to ensure stability during drilling operations. The power unit is used to provide power for the drilling process, and includes an electric motor, a magnetic ball hinge device, a main drill barrel control magnetic ball, a spring inside the main drill barrel and a wire storage room. The linear drilling mechanism is responsible for the linear drilling of the equipment. Operation, including a first-level hydraulic welding rod and a first-level hydraulic rod; the variable-angle drilling mechanism is used to change the drilling direction as needed after the linear drilling reaches a predetermined depth, including a drill bit connecting ball joint, a hydraulic rod on the left side of the drill bit, a hydraulic rod on the right side of the drill bit, a magnetic ball attached to the first-level hydraulic rod, a drill bit control magnetic ball, a spring and drill teeth inside the drill bit; the operation control box is used to control the operation of the equipment, including the main switch of the equipment, the power-on switch for the main drill barrel control magnetic ball, the first-level hydraulic control rod, the power-on switch for the drill bit control magnetic ball, the hydraulic control rod on the left side of the drill bit and the hydraulic control rod on the right side of the drill bit.

[0008] Preferably, the fixed base and its upper equipment can also be connected by a ball joint, which can realize the orientation adjustment of the initial drilling, but fixing frames must be placed on the corresponding two sides of the main drill barrel shell to ensure the stability of the equipment when tilted.

[0009] Preferably, the magnetically attractive ball joint device includes a ball joint supporting surface, a ball joint roller and a ball joint connecting rod from bottom to top. The lower part of the ball joint supporting surface is smoothly welded to the motor, and the upper part has a curved surface for the free rotation of the ball joint roller. The ball joint connecting rod is welded above the ball joint roller, and the ball joint connecting rod is made of a magnetically attractive product. It is worth mentioning that the ball joint roller of the magnetically attractive ball joint device will carry the welded ball joint connecting rod to rotate freely 360° after the motor is turned on.

[0010] Preferably, the main drill barrel control magnetic ball is used in conjunction with the spring attached to the main drill barrel. Specifically, the spring attached to the main drill barrel is welded to the inner wall of the main drill barrel and can expand and contract under magnetic attraction; the main drill barrel control magnetic ball is welded to the spring attached to the main drill barrel. After the motor provides current, electromagnetism occurs, so that the main drill barrel control magnetic ball has strong magnetism, and then quickly attracts the ball hinge connecting rod in the magnetic ball hinge device, and drives the ball hinge connecting rod to rotate during the rotation of the ball hinge roller, thereby driving the main drill barrel control magnetic ball to rotate, and further driving the main drill barrel to rotate.

[0011] Preferably, the upper part of the first-level hydraulic welding rod is welded to the lower part of the first-level hydraulic rod, and the lower part of the first-level hydraulic welding rod is welded to the ball joint connecting rod of the magnetic ball joint device. When the ball joint roller of the magnetic ball joint device drives the ball joint connecting rod to rotate, the first-level hydraulic welding rod rotates accordingly, and the ball joint connection function of the magnetic ball joint device can realize the left and right rotation of the first-level hydraulic welding rod and the first-level hydraulic rod within a certain range; the first-level hydraulic rod, the left hydraulic rod of the drill bit and the right hydraulic rod of the drill bit are all hydraulic devices, which can be extended and deflected under the control of the switch.

[0012] Preferably, the magnetic ball attached to the first-level hydraulic rod is welded to the upper part of the first-level hydraulic rod, and is made of a magnetic material; the working principle of the drill bit control magnetic ball and the spring inside the drill bit is consistent with the working principle of the above-mentioned main drill barrel control magnetic ball and the spring inside the main drill barrel, and they are all used in conjunction; the drill bit control magnetic ball generates magnetism when power is turned on, and can be attracted to the magnetic ball attached to the first-level hydraulic rod, and rotates with the rotation of the magnetic ball attached to the first-level hydraulic rod, and drives the drill bit to rotate, and then the drill teeth on the drill bit start to cut the coal rock to drill.

[0013] Preferably, the main switch of the equipment is used to control the start and stop of the motor and manage the overall operating status of the drilling equipment; the main drill barrel control magnetic ball power switch is used to control the power on and off of the main drill barrel control magnetic ball to achieve magnetic attraction and release; the first-level hydraulic control rod is used to control the up and down lifting and left and right deflection of the first-level hydraulic rod to adjust the depth and direction of the drilling hole; the drill bit control magnetic ball power switch is used to control the power on and off of the drill bit control magnetic ball to achieve magnetic attraction control and rotation of the drill bit; the left side hydraulic control rod of the drill bit controls the up and down lifting and left and right deflection of the left side hydraulic rod of the drill bit; the right side hydraulic control rod of the drill bit is used to control the up and down lifting and left and right deflection of the right side hydraulic rod of the drill bit.

[0014] Preferably, the drill teeth are connected to the drill bit by a threaded connection so that they can be replaced when the drill teeth are severely worn; in addition, the present invention also proposes two drill tooth shapes, one of which is a solid drill tooth, which is mainly used for drilling and quickly excavating through holes through strong rigidity; the other is a hollow drill tooth, which is mainly used for grouting, hydraulic fracturing and other fluid operations after drilling is completed.

[0015] The motor provides a power source for drilling. It is worth mentioning that the motor can also be designed and changed to a pneumatic type;

[0016] It is worth mentioning that all equipment and devices that require power from the motor are connected by wires. In order to protect the wires from being damaged by coal and rock during the drilling process, an outer wall is set outside the main drill barrel, and a wire storage room is formed between the inner wall and the outer wall. All wires are placed in the wire storage room.

[0017] It is worth mentioning that the length of the hydraulic rods of all the hydraulic equipment can be adjusted according to the specific drilling depth and position;

[0018] It is also worth mentioning that the metal live parts need to be insulated to prevent construction workers from getting electric shock.

[0019] The present invention also provides a method for using a directional drilling device capable of rotating an angle, the method comprising the following steps:

[0020] S1. Place the fixed base of the drilling equipment on the flat ground in the area where the drilling is to be done, turn on the main switch of the equipment, and start the motor;

[0021] S2. Perform linear drilling and turn on the power switch for the magnetic ball controlled by the main drill barrel. At this time, the magnetic ball controlled by the main drill barrel generates current, thereby generating magnetism. Under the attraction of the ball joint connecting rod on the magnetic ball joint device, the spring inside the main drill barrel is rapidly stretched, so that the magnetic balls controlled by the main drill barrels on the left and right sides are connected to the magnetic ball joint device. Then, the motor provides power, and the ball joint rollers in the magnetic ball joint device rotate rapidly. The ball joint connecting rod welded to it rotates, and the magnetic balls controlled by the main drill barrels on the left and right sides generate rotational power, driving the main drill barrel to rotate. At this time, the hydraulic rod on the left side of the drill bit and the hydraulic rod on the right side of the drill bit are partially retracted.

[0022] S3. When the straight drilling reaches the predetermined distance and the direction needs to be changed, the power switch of the main drill barrel control magnetic ball is turned off. At this time, the control magnetic balls of the left and right main drill barrels are disconnected from the magnetic ball hinge device. The main drill barrel loses power and stops rotating. Then, the first-level hydraulic control rod is operated to extend the first-level hydraulic rod upward until it reaches the position of the drill head control magnetic ball;

[0023] S4. Simultaneously, the drill bit controls the magnetic ball to be powered on, thereby obtaining magnetism and attracting the magnetic ball attached to the primary hydraulic rod to be magnetically connected thereto. The drill bit then obtains power and can achieve rotary drilling.

[0024] S5. Open the left and right hydraulic control levers of the drill bit, and according to the geological structure and the required adjustment angle, extend and retract the left and right hydraulic levers of the drill bit up and down to change the angle of the entire drill bit. Simultaneously, use the first hydraulic control lever to adjust the extension length and left and right angle of the first hydraulic lever to match the adjustment position of the drill bit as much as possible, and further perform variable-angle drilling;

[0025] S6. After drilling is completed, first adjust the hydraulic rods on the left and right sides of the drill bit, retract the drill bit part that has been deflected, and completely retract it to its original state before it was started. Then turn off the main switch of the equipment, retract the drilling equipment, and clean the equipment and the site.

[0026] Compared with related technologies, the directional drilling equipment with a rotatable angle and the method of using the same provided by the present invention have the following beneficial effects:

[0027] (1) The drilling angle can be adjusted as needed to adapt to different geological conditions and drilling targets, with greater flexibility. By precisely controlling the drilling direction, it can ensure that specific underground structures or layers are drilled;

[0028] (2) It can reduce the number of adjustments and the number of holes drilled during the drilling process, reduce ineffective drilling, save materials and energy, improve drilling efficiency, and shorten the project cycle. At the same time, it can avoid vertical drilling under unstable or dangerous geological conditions and reduce drilling risks.

[0029] (3) The operation is simple and does not require high theoretical and technical skills from front-line workers, which can greatly reduce manpower and material resources. At the same time, different drill tooth shapes can meet different engineering needs, and can not only complete drilling, but also realize grouting and hydraulic fracturing.
