[0043] In this application, all drawings are schematic and are used only to illustrate the principles of the invention, and are not drawn to scale. Detailed Implementation

[0044] The invention will now be described with reference to the accompanying drawings.

[0045] It should be noted that the directional terms or qualifiers used in this application, such as "up," "down," "front," "back," "left," and "right," are all specific to the referenced material. Figure 1 In other words, they are not used to define the absolute position of the components involved, but can vary depending on the specific circumstances.

[0046] Figure 1 The structure of a fully automated drilling rig surface hydraulic power system 100 according to the present invention is shown. (See diagram below.) Figure 1 As shown, the fully automatic drilling rig ground hydraulic power system 100 mainly includes a housing 1, an oil tank assembly 3, a pump assembly 2, an electrical control assembly 4, and a cooler assembly 5.

[0047] The oil tank assembly 3, pump assembly 2, and electrical control assembly 4 are all located inside the chamber 1. The electrical control assembly 4 is electrically connected to the pump assembly 2, providing power to it. The pump assembly 2 is connected to the oil tank assembly 3, driving the flow of hydraulic oil within it to provide hydraulic pressure for the drilling rig's auxiliary equipment. The cooler assembly 5 is located on the side wall of the chamber 1 and connected to the oil tank assembly 3, regulating the temperature of the hydraulic oil within it.

[0048] According to the present invention, the oil tank assembly 3 includes a hydraulic oil tank 31 for holding hydraulic oil, and an air capsule is provided on the hydraulic oil tank 31. The air capsule is configured to isolate the interior of the hydraulic oil tank 31 from the outside and realize pressure compensation inside the hydraulic oil tank 31.

[0049] Specifically, the air capsule is made of a flexible material and has a through-hole at the top of the hydraulic oil tank 31. The air capsule is positioned at this through-hole, effectively sealing it. When the hydraulic oil level in the hydraulic oil tank 31 fluctuates, the internal space changes, affecting the hydraulic oil pressure. By incorporating the air capsule, the system can adaptively expand or contract according to the vacuum level within the hydraulic oil tank 31, reducing vacuum fluctuations and preventing pressure changes. This allows the fully automatic drilling rig ground hydraulic power system 100 to provide stable pressure to the drilling rig's ground equipment.

[0050] According to the present invention, the ground supporting equipment for drilling rigs mainly includes drilling rig lifting hydraulic cylinders, drilling rig stepping devices, blowout preventer integrated transport devices, lifting robots, etc.

[0051] In this embodiment, as Figure 2 As shown, the chamber 1 has a square cavity structure. Side doors 12 are provided on both the left and right sides of the chamber 1, and a front door 11 is provided on the front side of the chamber 1. The chamber 1 can be opened through the front door 11 and the side doors 12, so that various operations can be performed on the oil tank assembly 3, pump assembly 2, electrical control assembly 4 and cooler assembly 5 inside the chamber 1, such as maintenance and manual adjustment of hydraulic parameters.

[0052] The pump assembly 2 includes at least one main pump group 21 and at least one auxiliary pump group, both of which are constant power variable pumps. The main pump group 21 has a higher power than the auxiliary pump group. The main pump group 21 provides power for high-flow, high-pressure drilling rig ground equipment, while the auxiliary pump group provides power for low-flow, medium-low-pressure drilling rig ground equipment.

[0053] like Figure 4As shown, in this embodiment, the pump assembly 2 includes a main pump group 21, a first auxiliary pump group 22, and a second auxiliary pump group 23, which are fixedly installed side by side on the bottom surface of the housing 1. The inlet ends of the main pump group 21 and the auxiliary pump group are connected to the hydraulic oil tank 31, and the outlet ends of the main pump group 21 and the auxiliary pump group are connected to the overflow valve group 35.

[0054] The inlet ends of the main pump group 21, the first auxiliary pump group 22, and the second auxiliary pump group 23 are respectively connected to the hydraulic oil tank 31 through pipelines. Taking the main pump group 21 as an example, the main pump group 21 is fixedly connected to the hydraulic oil tank 31 through the suction pipe 24, the flexible joint 25, the valve 26, and the suction filter 27.

[0055] The liquid outlets of the main pump group 21, the first auxiliary pump group 22, and the second auxiliary pump group 23 are connected to the overflow valve group 35 via oil outlet pipes and overflow valve group 35. Specifically, as shown... Figure 3 As shown, the outlet ends of the main pump group 21, the first auxiliary pump group 22 and the second auxiliary pump group 23 are connected to the overflow valve group 35 through the first oil outlet pipe 6, the second oil outlet pipe 7 and the third oil outlet pipe 8, respectively. The overflow port of the overflow valve group 35 is connected to the hydraulic oil tank 31.

[0056] In a preferred embodiment, the overflow valve assembly 35 is electrically connected to the control system in the driller's cabin. The set pressure of the overflow valve assembly 35 can be adjusted by inputting the corresponding pressure value through the touch screen of the control system in the driller's cabin, and the flow rate is automatically adjusted according to the load conditions.

[0057] like Figure 1 and Figure 10 As shown, a connector assembly 10 for supporting the overflow valve group 35 and various oil supply pipes is provided on the housing 1. The overflow valve group 35 is located on the upper part of the hydraulic oil tank 31. The overflow valve group 35 is connected to the connector assembly 10 and has multiple oil supply pipes, each of which is connected to the corresponding drilling rig ground equipment. The number of oil supply pipes corresponds to the number of pump groups in the pump assembly 2. In this embodiment, the main pump group 21, the first auxiliary pump group 22, and the second auxiliary pump group 23 correspond to the first oil supply pipe 61, the second oil supply pipe 62, and the third oil supply pipe 63 connected to the outlet of the overflow valve group 35, respectively.

[0058] After any one of the main pump group 21, the first auxiliary pump group 22, and the second auxiliary pump group 23 is started, it pumps the hydraulic oil in the hydraulic oil tank 31. Taking the main pump group 21 as an example, after the main pump group 21 is started, the hydraulic oil flows out of the hydraulic oil tank 31 and passes through the suction filter 27, valve 26, flexible joint 25, suction pipe 24, main pump group 21, first outlet pipe 6, overflow valve group 35, and first supply pipe 61 in sequence, flowing to the corresponding drilling rig ground supporting equipment.

[0059] In this embodiment, valve 26 is a manual butterfly valve. The suction filter 27 is located inside the hydraulic oil tank 31 to prevent pipe blockage.

[0060] According to the present invention, one end of the cooler assembly 5 is connected to the hydraulic oil tank 31 via a circulation pump 39, and the other end is connected to the hydraulic oil tank 31 via a first return oil filter 34. Specifically, as Figure 5 As shown, the circulating pump 39 and the first return oil filter 34 are both fixedly installed at the upper end of the hydraulic oil tank 31 and are connected to the interior of the hydraulic oil tank 31. After the circulating pump 39 starts, it pumps the hydraulic oil in the hydraulic oil tank 31 to the cooler assembly 5. After the hydraulic oil is cooled by the cooler assembly 5, it returns to the hydraulic oil tank 31 through the first return oil filter 34. This arrangement cools the hydraulic oil in the hydraulic oil tank 31 and filters impurities from the hydraulic oil tank 31.

[0061] In a preferred embodiment, the hydraulic oil tank 31 can be filled with oil via the cooler assembly 5.

[0062] In a specific embodiment, such as Figure 8 and Figure 9 As shown, the cooler assembly 5 includes a motor 51, a fan 53, and a protective cover 52. The motor 51 is fixedly mounted on the side wall of the housing 1, the fan 53 is coaxially mounted on the output shaft of the motor 51, and the protective cover 52 covers the outside of the fan 53. The cooler assembly 5 also includes a cooling pipe (not shown in the figure), one end of which is connected to a circulation pump 39, and the other end is connected to a first return oil filter 34. The cooling pipe passes through the fan 53, thereby enabling the fan 53 to drive airflow and cool the hydraulic oil in the cooling pipe.

[0063] According to the present invention, the hydraulic oil tank 31 is provided with any one or more of the following: an electric heater 36, a pressure gauge 37, a level switch 38, a cleaning cover 310, and a level gauge 311.

[0064] like Figure 5 As shown, in this embodiment, the electric heater 36 is fixedly installed on the left side of the hydraulic oil tank 31. When the temperature of the hydraulic oil in the hydraulic oil tank 31 is lower than the required temperature, the electric heater 36 can raise the temperature of the hydraulic oil in the hydraulic oil tank 31.

[0065] Pressure gauge 37 is located at the top of hydraulic oil tank 31 and extends into hydraulic oil tank 31. Pressure gauge 37 can monitor the pressure inside hydraulic oil tank 31 in real time.

[0066] The level gauge 311 is located on the left side of the hydraulic oil tank 31 and can monitor the level of hydraulic oil in the hydraulic oil tank 31 in real time.

[0067] The level switch 38 is located at the center of the upper end of the hydraulic oil tank 31. When the amount of hydraulic oil in the hydraulic oil tank 31 is higher or lower than the preset range, the level switch 38 will issue an alarm.

[0068] like Figure 6 As shown, three cleaning covers 310 are arranged side by side in the transverse direction on the front side of the hydraulic oil tank 31. After opening the cleaning covers 310, the interior of the hydraulic oil tank 31 can be cleaned.

[0069] At least one return oil filter is also installed on the hydraulic oil tank 31 for connecting to the return oil end of the drilling rig's ground-mounted equipment. For example... Figure 10 As shown, in this embodiment, a second return oil filter 32 and a third return oil filter 33 are provided on the hydraulic oil tank 31. The second return oil filter 32 and the third return oil filter 33 are respectively connected to the return oil end of the drilling rig ground equipment through the first return oil pipe 71 and the third return oil pipe 73, so as to receive the hydraulic oil used up by the drilling rig ground equipment.

[0070] According to the present invention, the electrical control component 4 includes a high-voltage electrical control cabinet 41, a signal electrical control cabinet 42, and a cable plug-in box 43.

[0071] The high-voltage electrical control cabinet 41 is used to supply power to the pump assembly 2.

[0072] The signal control cabinet 42 is used to control the operating status of the main pump group 21, the first auxiliary pump group 22, the second auxiliary pump group 23, the oil tank assembly 3, and the cooler assembly 5. Specifically, the signal control cabinet 42 is equipped with a PLC, control circuit, power supply module, etc., and has emergency stop, start, and stop buttons for the main pump group 21, the first auxiliary pump group 22, and the second auxiliary pump group 23, as well as operation indicator lights for the main pump group 21, the first auxiliary pump group 22, and the second auxiliary pump group 23, and indicator lights for the cooler assembly 5, the electric heater 36, and the liquid level alarm.

[0073] The cable insertion box 43 is located on the left side of the housing 1 and is used to connect to the electrical equipment of the drilling rig.

[0074] The high-voltage electrical control cabinet 41 and the signal electrical control cabinet 42 are located at the corresponding front opening door 11 of the room body 1. After opening the front opening door 11, the high-voltage electrical control cabinet 41 and the signal electrical control cabinet 42 can be operated directly.

[0075] The steps for using the fully automatic drilling rig ground hydraulic power system 100 are as follows.

[0076] Open the front door 11, connect the electrical control component 4 to the 380V power supply, and convert it to 220V and 24V through the transformer, switching power supply, etc. to power the electrical components. The high-voltage electrical control cabinet 41 supplies power to the pump assembly 2. Start the operation knobs of each device in the signal control cabinet 42, the indicator lights will light up, and oil supply will begin.

[0077] In pump assembly 2, the main pump group 21, the first auxiliary pump group 22, and the second auxiliary pump group 23 draw hydraulic oil through the suction filter 27 on the hydraulic oil tank 31. One-way valves are installed on the first outlet pipe 6, the second outlet pipe 7, and the third outlet pipe 8. The maximum working pressure of each line is set through the relief valve group 35. The main pump group 21 provides power for high-flow, high-pressure equipment, while the first auxiliary pump group 22 and the second auxiliary pump group 23 provide power for low-flow, medium-pressure equipment.

[0078] A manual directional valve 9 is also provided on the joint assembly 10. The manual directional valve 9 is connected to the drilling rig ground supporting equipment such as BOP hoisting, upper buckling machine, derrick hoisting, and sliding system through the fifth oil supply pipe 65. The oil return end of these drilling rig ground supporting equipment is connected to the hydraulic oil tank 31 through the fifth oil return pipe 75.

[0079] The cooler assembly 5 can be automatically turned on by program control or manually turned on. The circulating pump 39 draws in hydraulic oil and delivers it to the cooler assembly 5. The motor 51 drives the fan 53 to rotate, which cools the hydraulic oil. The cooled hydraulic oil then returns to the hydraulic oil tank 31 through the first return oil filter 34.

[0080] like Figure 10 As shown, a drain pipe 81 is provided on the connector assembly 10, and the drain pipe 81 is connected to the hydraulic oil tank 31. The drain pipe 81 is opened when changing the hydraulic oil to release the hydraulic oil in the hydraulic oil tank 31, and then new hydraulic oil is replaced.

[0081] The electric heater 36 can be automatically or manually started by program control to heat the hydraulic oil to meet the operating conditions and ensure a suitable oil temperature supply.
