[0010] The beneficial effects of the present invention are as follows:

[0011] 1. The present invention is provided with an oscillation component. Through the structural design of the oscillation component, the energy of liquid flow can be converted into rotational power, thereby generating oscillation. The rotating shaft, blades, connecting shaft, connecting tube, connecting sleeve and paddles work together. When liquid flows through, the blades and paddles are subjected to the force of the fluid to rotate the rotating shaft. This multi-component linkage method can generate sufficient and stable oscillation force, which can be transmitted to the drill bit to help the drill bit better break rocks and improve drilling efficiency.

[0012] 2. The present invention provides an oscillation component. The hydrophobic groove in the blade wall not only helps the liquid to pass quickly to reduce resistance and make the rotation smoother, but also prevents mud and sand blocks from blocking the rotation of the blades, thereby ensuring the continuous and stable operation of the oscillation component, reducing drilling interruptions caused by blade blockage and other faults, and further improving the overall drilling efficiency.

[0013] 3. The present invention guides and regulates the flow of liquid by arranging guide column 1, guide column 2, guide column 1, guide column 2 and their related diverter head 1, diverter head 2, guide vanes, guide holes, spiral grooves, spiral holes and guide groove 1 structures. They enable the liquid to flow along a specific trajectory and flow rate, ensure that the liquid impacts the blades evenly, maintain the stable working state of the oscillation component, and avoid oscillation instability caused by uneven liquid flow.

[0014] 4. The present invention provides bearings which support the rotating shaft, thereby reducing friction resistance during rotation and ensuring the rotation accuracy of the rotating shaft. This not only helps to improve the working efficiency of the oscillation component, but also extends the service life of key components such as the rotating shaft, thereby ensuring long-term and stable operation of the equipment.

[0015] 5. The present invention prevents leakage of drilling fluid or other liquids from the connection between the joint and the shell by setting a sealing gasket, thereby maintaining the pressure balance in the device, which is crucial for the stable operation of the equipment in a high-pressure underground environment. It avoids the influence of internal pressure changes caused by liquid leakage on the working performance of each component and ensures the reliability of the entire gyroscopic oscillator.

[0016] 6. The present invention provides a filtering assembly, which is composed of a fixing ring, a guide hemisphere, a mounting column, a mounting ring, a water diversion groove, a second guide groove, a spiral groove and a drainage groove. It can filter impurities in the drilling fluid. When the drilling fluid enters the device, larger impurities are blocked outside the guide hemisphere, and fine impurities are further separated by the second guide groove and the spiral groove to prevent impurities from entering the interior of the device, avoiding impurities from causing wear or blockage to internal components such as bearings, oscillation components, etc., thereby extending the service life of the equipment.

[0028] Working principle:

[0029] The gyroscopic oscillator is mainly composed of a housing 1, a joint 2, a filter assembly 4, a guide column 1 7, a guide column 2 13, an oscillation assembly 5 and other components. These components cooperate with each other to achieve the oscillation function during the drilling process.

[0030] The outer wall of the joint 2 is snap-fitted with the inner wall of the shell 1 , and the shell 1 provides a space for accommodating and protecting various components inside, ensuring that the internal components can work normally in a harsh drilling environment.

[0031] The oscillation component 5 is the core part for generating the oscillation effect, and includes a rotating shaft 51, blades 52, a drain groove 53, a connecting shaft 54, a connecting tube 55, a connecting sleeve 56 and a paddle 57. The rotating shaft 51 serves as the rotation center of the entire oscillation component 5, and the blades 52 fixedly connected to its outer wall are arranged in a circular array along the central axis of the rotating shaft 51. When liquid flows through, the blades 52 will be affected by the force of the fluid, thereby causing the rotating shaft 51 to start rotating. The drain groove 53 in the wall of the blade 52 helps the liquid to pass quickly, reduces the resistance of the blade 52, and makes the rotation smoother. When the mud and sand accumulate inside the shell 1, the blocks generated can flow out through the drain groove 53, thereby preventing the blocks from blocking the rotation of the blade 52.

[0032] The connecting shaft 54 ​​connects the rotating shaft 51 with the connecting tube 55. The paddles 57 fixedly connected to the connecting sleeve 56 on the outer wall of the connecting tube 55 are arranged in a circular array along the central axis of the connecting sleeve 56. These paddles 57 are also affected by the fluid, forcing the paddles 57 to drive the connecting shaft 54 ​​to rotate, further enhancing the rotational power of the entire oscillation component 5.

[0033] The outer wall of the guide column 13 is fixedly connected with a diverter head 9, and the outer wall of the guide column 17 is fixedly connected with a diverter head 8. During operation, liquid enters through the guide column 13, and the diverter head 9 can divert and discharge the incoming liquid, while the guide column 17 and its diverter head 8 divert the incoming liquid, so that the liquid flows evenly through the guide column 7, ensuring that the flow direction of the liquid can evenly impact the blade 52.

[0034] The outer wall of the splitter head 2 9 is fixedly connected with a guide vane 11, and the guide vane 11 is arranged in a circular array along the central axis of the splitter head 2 9. The wall of the guide column 2 13 is provided with a guide hole 14, and the guide hole 14 is arranged in a circular array along the central axis of the guide column 2 13. The guide vane 11 can further guide the liquid to flow out of the oscillator, and the liquid entering is guided by the guide vane 11, so that the liquid is forced to flow along the outer wall of the guide vane 11, thereby changing the flow direction of the liquid, and guiding it through the spiral groove 10 on the joint 2, so as to accelerate the liquid to be discharged from the oscillator, and the spiral hole 18 on the shell 1 can play a role in the flow of the liquid. A certain acceleration effect is achieved, so that the liquid can flow along a specific trajectory when entering the device, and the spiral liquid hits the blade 52, further increasing the kinetic energy of the blade 52. The guide hole 14 is used to adjust the flow rate of the liquid in the guide column 13. A guide groove 19 is opened in the wall of the shell 1 away from the joint 2 and is arranged in a circular array along the central axis of the shell 1. The guide groove 19 can guide the liquid in the device to avoid eddy currents or stagnation in local areas of the liquid, thereby ensuring the smooth flow of the liquid in the device, thereby ensuring that each component can perform its function normally.

[0035] The inner wall of the guide column 13 is rotatably connected to a bearing 16, and the side of the rotating shaft 51 close to the joint 2 is fixedly connected to the inner wall of the bearing 16. The function of the bearing 16 is to support the rotation of the rotating shaft 51, reduce the friction resistance of the rotating shaft 51 during the rotation process, improve the rotation efficiency, and at the same time ensure the rotation accuracy of the rotating shaft 51, ensuring that the oscillation component 5 can stably produce an oscillation effect.

[0036] A sealing gasket 15 is clamped on the outer wall of the joint 2, and the outer wall of the sealing gasket 15 is clamped on the inner wall of the shell 1. The main function of the sealing gasket 15 is to prevent drilling fluid or other liquids from leaking from the connection between the joint 2 and the shell 1, ensure that the liquid inside the device can flow in a relatively closed environment, maintain the pressure balance in the device, and ensure that each component can work normally.

[0037] The filter assembly 4 includes a fixing ring 41, a guide hemisphere 44, a mounting column 42, a mounting ring 43, a water diversion groove 47, a second guide groove 46, a spiral groove 45 and a drainage groove 48. This structural design allows the filter assembly 4 to be easily installed and disassembled, and is convenient for maintenance and replacement.

[0038] During the drilling process, drilling fluid and other liquids first enter the filter component 4, and the water diversion groove 47 can guide the liquid into the guide hemisphere 44. In this process, some larger impurities will be blocked outside the guide hemisphere 44, and the liquid passing through the water diversion groove 47 will first enter the spiral hole 18 along the guide groove 1 19. The guide groove 2 46 and the spiral groove 45 can further guide and filter the incoming liquid to separate the fine impurities in the liquid. Finally, the filtered liquid enters the device through the drainage groove 48. The filter component 4 effectively prevents impurities from entering the device, protects the internal components, extends the service life of the device, and ensures the smooth flow of liquid in the device.
