Description

Technical Field

[0001] This invention relates to the field of oil drilling and production equipment technology, and in particular to an ultra-quiet hydraulic station for oil drilling rigs. Background Technology

[0002] The hydraulic station of an oil drilling rig is the core power unit for drilling operations. Its noise mainly comes from mechanical vibrations, aerodynamic noise, and high-pressure fluid pulsation noise from motors, hydraulic pumps, fans, etc. Traditional noise reduction methods often use local sound insulation, which often leads to poor heat dissipation and maintenance difficulties. Moreover, it is difficult to solve the problem of multiple noise source coupling. In view of the dual requirements of low noise and high reliability at the drilling site, there is an urgent need for an innovative solution that can systematically reduce noise from the source of structural design and take into account efficient heat dissipation. Summary of the Invention

[0003] This invention provides an ultra-quiet hydraulic station for oil drilling rigs, which solves the shortcomings of existing technologies where traditional noise reduction methods often use local sound insulation, which often leads to deterioration of equipment heat dissipation, maintenance difficulties, and difficulty in solving the coupling of multiple noise sources.

[0004] This invention provides the following technical solution: An ultra-quiet hydraulic station for oil drilling rigs includes a hydraulic station frame, a hydraulic pump set, an electrical control system, an oil tank, a cooling system, a refueling pump set, a control valve set, a multi-source sensor, a sound insulation panel, and a vibration damping mechanism. The hydraulic station frame has a physically isolated first compartment and second compartment. The first compartment centrally houses the hydraulic pump group, the heat dissipation system, and the refueling pump group. Each unit component is enclosed by a sound insulation panel to form a sound insulation structure for each unit component. Furthermore, the circumference of the first compartment is enclosed by a sound insulation panel to form an overall sound insulation structure for noise transmission blocking. The sound insulation panels are all fixed to the inner wall of the hydraulic station frame. The second compartment mainly houses the fuel tank, and the fuel tank wall panel is equipped with heat dissipation fins; The electronic control system includes an intelligent control module, an intelligent temperature controller, a noise reduction management system, and a control circuit. The intelligent control module, intelligent temperature controller, noise reduction management system, and control circuit are installed in an explosion-proof box on the top of the hydraulic station frame. The electronic control system is electrically connected to the multi-source sensors to dynamically manage the system's operating status and realize intelligent system control.

[0005] Furthermore, the sound insulation board has a multi-layer composite structure, including an outer steel plate, a sound insulation damping layer, a sound absorption layer, and a sealing strip from the outside to the inside. The outer steel plate is recessed and has grooves on its protruding parts around the perimeter. The sound insulation damping layer and the sound absorption layer are fixed inside the outer steel plate, and the sealing strip is snapped into the grooves.

[0006] Furthermore, the hydraulic pump assembly includes at least two drive motors and a hydraulic pump. The drive motors are fixed to the bottom inner wall of the hydraulic station frame, and the hydraulic pumps are fixed to one side of the drive motors. The drive end of the hydraulic pump is fixed to the output shaft of the drive motor. The suction end and discharge end of the hydraulic pump are fixedly connected to the oil tank through pipelines. The pressure end of the hydraulic pump is provided with a main hydraulic pipeline assembly. The hydraulic pump is connected to a control valve assembly fixed to the bottom of the hydraulic station frame through the main hydraulic pipeline assembly.

[0007] Furthermore, the main hydraulic pipeline assembly includes a main hydraulic pipeline, which is fixedly connected to the oil pressure end of the hydraulic pump. The main hydraulic pipeline adopts an enlarged diameter and smooth transition design, and a large radius elbow is used at the bend, with its bending radius R being more than three times the diameter D of the main hydraulic pipeline, in order to achieve fluid pulsation attenuation.

[0008] Furthermore, the heat dissipation system includes a heat dissipation fan, a cooler, heat dissipation pipes, and heat dissipation fins. The cooler is fixed to the bottom surface of the hydraulic station frame, the heat dissipation fan is fixed to one side of the cooler, the heat dissipation pipes are connected to the hydraulic pipes, and the heat dissipation fins are fixed to the oil tank and the outer wall of the second compartment.

[0009] Furthermore, the refueling pump assembly includes a refueling motor and a refueling pump. The refueling motor is fixed to the bottom surface of the hydraulic station frame, and the refueling pump is fixed to one side of the refueling motor. The drive end of the refueling pump is fixed to the output shaft of the refueling motor.

[0010] Furthermore, the drive motor, cooling fan, and refueling motor are all low-speed silent motors, which are three-phase asynchronous motors with 6 or more poles, to suppress vibration sources.

[0011] Furthermore, the multi-source sensors include a pressure sensor, an oil level sensor, a temperature sensor, and a vibration sensor. The intelligent control module is configured to dynamically adjust the operating parameters of the heat dissipation system based on the sensor signals and to provide equipment status warnings. The pressure sensor is fixed to the control valve group to monitor its pressure, the oil level sensor and the temperature sensor are fixed to the oil tank to monitor the oil tank status, and the vibration sensor is fixed to the drive motor housing and the hydraulic pump body, respectively.

[0012] Furthermore, a shock-absorbing mechanism is provided at the bottom of the hydraulic station frame. The shock-absorbing mechanism consists of multiple rubber shock-absorbing pads, which are fixed at the four corners of the bottom of the hydraulic station frame.

[0013] Furthermore, the shock absorption mechanism comprises multiple shock absorption sections, each disposed at one of the four bottom corners of the hydraulic station frame. Each shock absorption section includes a first sleeve and a second sleeve, both of which are fixed to the bottom of the hydraulic station frame. A piston rod slides through the bottom of the first sleeve, and a first piston is fixed to the top of the piston rod. The first piston slides against the inner wall of the first sleeve, and a pad is fixed to the bottom of the piston rod. A second piston and a push plate are slidably connected inside the second sleeve, and a spring is located between the second piston and the push plate. A screw is rotatably connected to one side of the push plate, and the screw thread passes through the second sleeve. A connecting pipe is fixedly connected between the first sleeve and the second sleeve, and hydraulic oil is disposed in the cavity between the first piston and the second piston.

[0014] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0015] In this invention, on the one hand, the main noise sources, such as the hydraulic pump unit, are centrally encapsulated through the combination of physical isolation between two compartments and multi-layer composite sound insulation panels, forming a dual sound insulation structure of units and the whole. This blocks the outward propagation of noise, solves the noise crosstalk problem of traditional hydraulic stations, significantly reduces operating noise, improves the comfort of the working environment at oil drilling sites, and meets the low-noise requirements of the site. On the other hand, the second compartment, as a heat dissipation functional area, mainly houses the oil tank, and its wall panels are equipped with heat dissipation fins and ventilation structures to meet heat dissipation requirements. This structure fundamentally separates the management paths for "noise" and "heat".

[0016] In this invention, the vibration source is suppressed from the source and the fluid pulsation is attenuated by the synergy of a low-speed silent motor, a hydraulic shock absorber and a large-radius elbow pipeline. At the same time, the vibration energy is offset by hydraulic damping and spring elasticity, reducing vibration transmission, avoiding pipeline vibration failure, and improving the overall operational stability and service life of the hydraulic station. In this invention, the speed of the cooling fan is dynamically adjusted by the cooperation of multi-source sensors and intelligent control module, which takes into account both heat dissipation efficiency and low noise operation. At the same time, the equipment status is monitored in real time and early warning is given, which facilitates timely maintenance, reduces maintenance costs, and ensures the continuous and stable operation of oil drilling rigs.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized.

[0023] Example 1 Reference Figures 1-7 An ultra-quiet hydraulic station for oil drilling rigs includes a hydraulic station frame 1, and a first compartment 101 and a second compartment 102 formed by welding steel plates to physically isolate them. In this embodiment, the first compartment 101 is located below and is the power compartment, while the second compartment 102 is located above and is the heat dissipation compartment. The partition between the two compartments has reserved pipe perforations, and the perforations are sealed with gaskets to avoid noise crosstalk.

[0024] The first compartment 101 houses the hydraulic pump unit 2, the cooling system 5, and the refueling pump unit 6. Each unit is individually enclosed by a soundproof panel 9 to form a unit soundproof structure. Simultaneously, the perimeter and top of the first compartment 101 are also enclosed by soundproof panels 9, forming an overall soundproof structure. The soundproof panel 9 is a multi-layered composite structure, consisting of, from the outside in, an outer steel plate 901, a sound-damping layer 902, a sound-absorbing layer 903, and a sealing strip 904. The outer steel plate 901 is concave overall and convex around its perimeter. The outer part has a groove. The sound insulation damping layer 902 is fixed to one side of the groove inside the outer steel plate 901. The sound absorption layer 903 is attached and fixed to the inner side of the sound insulation damping layer 902. The sealing strip 904 is snapped into the groove. After assembly, the sealing strip 904 is tightly attached to the inner wall of the hydraulic station frame 1 to achieve sealing and sound insulation and block the transmission of noise outward. All sound insulation panels 9 are fixed to the inner wall of the hydraulic station frame 1 by bolts. The bolt connection is fitted with a rubber sleeve to prevent the sound insulation panel 9 from loosening due to vibration.

[0025] Hydraulic pump unit 2 includes a drive motor 201 and a hydraulic pump 202. The drive motor 201 is fixed to the bottom inner wall of the hydraulic station frame 1 by anchor bolts. Rubber washers are fitted on the outside of the anchor bolts to reduce vibration transmission during motor operation. The hydraulic pump 202 is a large-displacement silent axial piston pump, fixed to one side of the drive motor 201. The drive end of the hydraulic pump 202 is fixedly connected to the output shaft of the drive motor 201. The oil suction end of the hydraulic pump 202 is connected to the oil suction port at the bottom of the oil tank 4 through a high-pressure rubber hose, and the oil discharge end is connected to the oil return port at the top of the oil tank 4 through a return pipe. Both ends of the oil suction pipe and the return pipe are fixed with clamps, and rubber bushings are provided on the inside of the clamps to reduce pipe vibration. To reduce road vibration, the hydraulic pump 202's oil pressure end is connected to the main hydraulic pipeline assembly 205. The main hydraulic pipeline assembly 205 includes a stainless steel main hydraulic pipeline, which adopts an enlarged diameter and smooth transition design. All bends use large-radius elbows, with the elbow bending radius being more than three times the diameter of the main hydraulic pipeline, which can effectively attenuate fluid pulsation and reduce fluid noise. The main hydraulic pipeline is fixed to the bottom of the hydraulic station frame 1 by vibration-damping pipe clamps with rubber liners, further reducing the noise generated by pipeline vibration. The end of the main hydraulic pipeline assembly 205 away from the hydraulic pump 202 is connected to the control valve group 7. The control valve group 7 is fixed to the bottom of the hydraulic station frame 1 by bolts and is located on one side of the hydraulic pump group 2.

[0026] The heat dissipation system 5 includes a cooling fan 501, a cooler 502, a heat dissipation pipe 503, and heat sinks 504. The cooler 502 is fixed to the bottom surface of the hydraulic station frame 1 by bracket bolts. The oil inlet and outlet of the cooler 502 are connected to the branch pipes of the main hydraulic pipeline assembly 205 through the heat dissipation pipe 503 to form a hydraulic oil cooling circuit. The heat dissipation pipe 503 is made of stainless steel and is welded to the main hydraulic pipeline. The connection is made of argon arc welding to ensure a leak-free seal. The cooling fan 501 is fixed on the air inlet side of the cooler 502 and is connected to the bottom of the hydraulic station frame 1 by a bracket. The air outlet of the fan faces the heat dissipation channel of the cooler 502. The heat sinks 504 are aluminum fins that are welded to the outer wall of the oil tank 4 and the outer wall of the second compartment 102. They are evenly distributed to increase the heat dissipation area and improve the heat dissipation efficiency.

[0027] The fuel pump assembly 6 includes a fuel motor 601 and a fuel pump 602. The fuel motor 601 is fixed to the bottom surface of the hydraulic station frame 1 by bolts and is located on one side of the cooler 502. The fuel pump 602 is fixed to one side of the fuel motor 601, and the drive end of the fuel pump 602 is fixedly connected to the output shaft of the fuel motor 601.

[0028] The drive motor 201, cooling fan 501 and fuel pump 601 all use low-speed silent motors, specifically six-pole or higher three-phase asynchronous motors. Low-speed operation can effectively suppress vibration sources and reduce noise generated by mechanical vibration, thereby reducing noise output from the source.

[0029] The second compartment 102 is equipped with an oil tank 4, which is made of welded steel plate and fixed to the bottom of the second compartment 102. The top of the oil tank 4 is equipped with an oil filling port, an oil return port and a vent cap, and the bottom is equipped with an oil suction port and a drain port. A drain valve is installed at the drain port to facilitate the periodic cleaning of impurities at the bottom of the oil tank 4. The wall panels of the second compartment 102 are processed with ventilation and heat dissipation holes. The ventilation holes are designed in the form of louvers to ensure air circulation and block some noise from spreading outward.

[0030] The electrical control system 3 includes an intelligent control module 301, an intelligent temperature controller 302, a noise reduction management system 303, and a control circuit 304. All components are installed in an explosion-proof box on top of the hydraulic station frame 1. The explosion-proof box is an explosion-proof structure that can adapt to the flammable and explosive environment at the oil drilling site. The explosion-proof box has an installation plate inside, and the intelligent control module 301, intelligent temperature controller 302, and noise reduction management system 303 are all fixed to the installation plate with bolts. The control circuit 304 uses flame-retardant wires, and the wiring is organized through wire troughs to avoid faults caused by messy wiring. The electrical control system 3 is electrically connected to the multi-source sensor 8 through wires to realize the real-time reception and processing of sensor signals and dynamically manage the system's operating status.

[0031] The multi-source sensor 8 includes a pressure sensor 801, an oil level sensor 802, a temperature sensor 803, and a vibration sensor 804. The pressure sensor 801 is fixed to the control valve group 7 via a threaded interface and is used to monitor the working pressure of the control valve group 7 in real time. The oil level sensor 802 is fixed to one side of the oil tank 4, with the sensor probe extending into the inside of the oil tank 4 to monitor the hydraulic oil level. The temperature sensor 803 is fixed to the temperature measurement interface on one side of the oil tank 4, with the probe inserted into the hydraulic oil to monitor the hydraulic oil temperature. The vibration sensor 804 is fixed to the housing of the drive motor 201 and the pump body of the hydraulic pump 202 respectively to monitor the vibration parameters during equipment operation. After receiving the signals from each sensor, the intelligent control module 301 can dynamically adjust the operating speed of the cooling fan 501 according to the hydraulic oil temperature data through the intelligent temperature controller 302. This ensures the cooling effect while reducing the fan operating noise. At the same time, the intelligent control module 301 can analyze the signals of the vibration sensor 804 through the noise reduction management system 303. When the vibration parameters exceed the set threshold, it will issue an equipment status warning to remind the staff to carry out maintenance.

[0032] Example 2 Reference Figures 1-7 An improved version of the ultra-quiet hydraulic station for oil drilling rigs is proposed based on Example 1.

[0033] The bottom of the hydraulic station frame 1 is equipped with a shock absorption mechanism 10. The shock absorption mechanism 10 includes two types of shock absorption structures: shock absorption pads 1011 and shock absorption parts. The shock absorption pads 1011 are made of rubber and there are four of them. They are fixed to the four corners of the bottom of the hydraulic station frame 1 by bolts to reduce the overall vibration of the equipment.

[0034] Four shock absorbers are also provided, located at the four corners of the bottom of the hydraulic station frame 1. Each shock absorber includes a first sleeve 1021 and a second sleeve 1025. Both the first sleeve 1021 and the second sleeve 1025 are welded to the bottom of the hydraulic station frame 1 and are arranged in parallel. A piston rod 1023 is slidably inserted through the bottom of the first sleeve 1021. A first piston 1022 is welded to the top of the piston rod 1023. The first piston 1022 slides with the inner wall of the first sleeve 1021. A sealing ring is fitted on the outside of the piston to ensure sealing performance. A pad 1024 is welded to the bottom of the piston rod 1023. A second piston 1027 and a push plate 1028 are slidably connected inside the second sleeve 1025. The second piston 1027 is located on one side of the push plate 1028, and a spring is provided between the two. 1029, the two ends of the spring 1029 are fixedly connected to the second piston 1027 and the push plate 1028 respectively. The other side of the push plate 1028 is rotatably connected to the screw 1030. The end of the screw 1030 away from the push plate 1028 is threaded through the end plate of the second sleeve 1025 and extends to the outside of the sleeve. The end of the screw 1030 is provided with an adjustment handle for easy rotation and adjustment. The first sleeve 1021 and the second sleeve 1025 are fixedly connected by the connecting pipe 1026. Hydraulic oil is injected into the cavity between the first piston 1022 and the second piston 1027 to form a hydraulic damping circuit. The push plate 1028 and the inner wall of the second sleeve 1025 achieve directional sliding through the slider groove. A sliding rod is fixed on one side of the second piston 1027. The sliding rod slides through the push plate 1028 to achieve guidance.

[0035] The working principle and usage process of this technical solution are as follows: The hydraulic station frame 1 is physically separated (partitioned) into a first compartment 101 and a second compartment 102. The lower first compartment 101 is the power compartment, and the upper second compartment 102 is the heat dissipation compartment. The power compartment is separated and covered by a sound insulation board 9 to form an acoustic shielding shell, thereby achieving a good noise reduction effect when the equipment is working. The drive motor 201, the cooling fan 501 and the oil refueling motor 601 are all low-speed silent motors with six or more poles and three-phase asynchronous motors. At the same time, the hydraulic pump 202 is a large-displacement silent axial piston pump, which further suppresses vibration sources and improves the noise reduction effect. The main hydraulic pipeline assembly 205 connecting the hydraulic pump 202 adopts an enlarged diameter design, all elbows are large-radius arcs (meeting R≥3D), and are fixed with vibration damping pipe clamps with rubber linings to achieve fluid pulsation attenuation. Together with the vibration damping mechanism 10 installed at the bottom of the hydraulic station frame 1, it reduces vibration noise. By rotating the screw 1030, the position of the push plate 1028 can be changed, and the second piston 1027 can be moved by the spring 1029. Through the flow of hydraulic oil, the pad 1024 can be made to contact the ground, thus adapting to uneven ground. When the hydraulic station frame 1 vibrates as a whole, the energy can be offset by the movement of the first piston 1022 and the second piston 1027, further reducing vibration noise.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
