Description

Technical Field

[0001] This utility model relates to the field of hydraulic device technology, and in particular to a power unit and cylinder connection structure for a deep-sea submersible oil pump and cylinder integrated hydraulic press. Background Technology

[0002] As the core driving component for realizing the opening and closing of underwater gates, the deep-sea oil pump and cylinder integrated hydraulic press needs to operate stably for a long time in extreme environments with high pressure and low temperature.

[0003] The structure of the deep-sea pump-cylinder integrated hydraulic press mainly consists of a power unit and a cylinder. The power unit provides oil and electrical signals to the cylinder, thereby driving the piston rod to extend and retract to realize the opening and closing of the gate or mechanical action, providing the opening and closing power for the stratified water intake gate. Although it can provide a certain degree of flexibility, since the deep-sea actuator is used in the low temperature and high pressure environment of deep water, the physical channels for oil delivery and electrical signal transmission are not spatially isolated, making it difficult to guarantee the sealing performance of the wiring layout between the power unit and the cylinder and the oil delivery process, which is prone to leakage. At the same time, during the operation of the deep-sea actuator, the wiring and oil pipeline are prone to mutual interference and entanglement, which can lead to actuation failure and make it difficult to guarantee the stability of operation. Moreover, maintenance requires disassembling both the oil circuit and the wiring at the same time, which is inconvenient for inspection and maintenance.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0017] Furthermore, both of the aforementioned seats are provided with pressure testing channels that communicate with the oil passage. The pressure testing channels are arranged to extend through the side of the pipe body, and a pressure testing connector is fixedly installed in the pressure testing channels.

[0018] Furthermore, the line channel includes a longitudinal section and a transverse section that are perpendicularly connected to each other. The port of the longitudinal section is located facing the power unit, and the port of the transverse section is located facing the pipe body and is fixedly connected to the end of the pipe body.

[0037] like Figures 1 to 9 The power unit and cylinder connection structure shown for a deep-sea submersible oil pump cylinder integrated hydraulic press include: two sets of connecting components 10 and a pipe body 20;

[0038] The connecting components 10 are respectively disposed on the corresponding sides of the rodless chamber and the rod chamber of the hydraulic cylinder 01, and are used to connect the hydraulic cylinder 01 and the power unit;

[0039] Each set of connecting components 10 has an independent oil passage 101 and a line passage 102. One end of the oil passage 101 is connected to the oil passage in the power unit, and the other end is connected to the rodless chamber or rod chamber of the cylinder 01 through the oil port 01a on the cylinder 01.

[0040] The wiring channel 102 is used to accommodate wiring from the power unit and / or cylinder 01. The tube body 20 is hollow and its two ends are respectively connected to the ports or the middle of the wiring channel 102 on both sides.

[0041] This invention connects the power unit and the cylinder 01 via two sets of connecting components 10 and a pipe body 20, greatly improving the integration level of the deep-sea oil pump and cylinder integrated hydraulic press. It also provides independent space for the oil passage 101 and the wiring passage 102. The oil can directly enter the rod chamber or rodless chamber through the connecting components 10. The connecting wire is laid in the pipe body 20 through the connecting components 10, avoiding mutual interference between the oil and the electrical signal transmission channel, reducing the risk of leakage, improving the sealing performance of the system, and reducing the problem of action failure caused by the interaction between the connecting wire and the oil. This improves the working stability of the actuator in the deep-water high-pressure environment. Moreover, the oil passage 101 or the wiring passage 102 can be directly inspected and maintained through the connecting components 10 or the pipe body 20, reducing maintenance costs and time.

[0042] When the actuator is working, the connecting assembly 10 guides the oil through the oil passage 101 into the rodless or rod chamber of the cylinder 01 according to the electrical signal from the power unit, thereby driving the piston rod to extend and retract, thus realizing the opening and closing action of the gate. The connecting lines are independently arranged in the external pipe 20 through the line passage 102 in the connecting assemblies on both sides, so that the electrical signal can be smoothly transmitted from the power unit to the cylinder 01, or from the cylinder 01 to the power unit, ensuring that the electrical signal can be transmitted stably and avoiding mutual interference.

[0043] The pipe body 20 can be made of soft or hard materials with good high pressure resistance and waterproof performance, depending on the needs of use in deep water environments. No specific limitation is made here.

[0044] Based on the above embodiments, each set of connecting components 10 includes a base 11 and a base plate 12, with the oil passage 101 and the line passage 102 located in the base 11; the base 11 is fixedly connected to the outside of the oil cylinder 01 through the base plate 12.

[0045] The base 11 is externally fixed to the cylinder 01 via the base plate 12, making the connection between the connecting component 10 and the cylinder 01 more stable and further improving the structural strength and reliability of the entire system. The separate design of the base 11 and the base plate 12 makes the disassembly of the connecting component 10 more convenient. During maintenance, it can be disassembled directly through the connection point between the base plate 12 and the cylinder 01 without the need for complex operations on the entire cylinder 01, further simplifying the maintenance process. Specifically, the external fixed connection of the base 11 to the cylinder 01 via the base plate 12 can be achieved through welding, bolts, or other fasteners, thereby ensuring the stability of the connection and the sealing of the assembly in deep water environments, and preventing oil leakage or water seepage.

[0046] Based on the above embodiments, the base 11 and the substrate 12 are provided with a pair of first positioning holes 11a, and the base 11 is positioned and fixedly connected to the substrate 12 through the first positioning holes 11a.

[0047] The substrate 12 and the oil cylinder 01 are provided with a pair of second positioning holes 01b; the substrate 12 is positioned and fixedly connected to the oil cylinder 01 through the second positioning holes 01b.

[0048] The design of the first positioning hole 11a and the second positioning hole 01b achieves precise positioning between the base 11 and the base plate 12, and between the base plate 12 and the cylinder 01. During assembly, the base 11 and the base plate 12 are aligned so that the first positioning hole 11a coincides, and the base plate 12 and the cylinder 01 are aligned so that the second positioning hole 01b coincides. This ensures the accuracy of the positioning connection between the base plate 12, the cylinder 01, and the base 11, reduces assembly errors, and ensures the accuracy of the oil passage's alignment with the oil inlet of the rod-side or rodless cavity. Specifically, the first or second connecting hole can be used with bolts, pins, or other fasteners for secure connection, facilitating assembly and disassembly and ensuring a stable and reliable connection.

[0049] Based on the above embodiment, a valve mounting hole is provided on the side of the seat 11 away from the tube 20, and a valve body 13 is fixedly connected to the seat 11 through the valve mounting hole. The valve body 13 is fixed on the seat 11 through the valve mounting hole and communicates with the oil passage 101. It can be used to adjust the oil passage's conduction, pressure, oil volume, etc., to ensure that the actuator operates stably under high pressure and realize the extension and retraction of the piston rod. Specifically, the valve body 13 can be connected to the valve mounting hole on the seat 11 by plugging or threading. During maintenance, it is only necessary to release the engagement between the valve body 13 and the valve mounting hole to separate the two, reducing the difficulty of assembly and disassembly during maintenance in deep water environments.

[0050] Based on the above embodiments, the oil passage 101 includes a first section 101a connected to the oil passage in the power unit, a second section 101b connected to the rodless or rod chamber of the cylinder 01, and two auxiliary sections 101c connected to the first section 101a and the second section 101b respectively. The auxiliary sections 101c are arranged through the side where the valve body 13 is located and are connected to the oil inlet and oil outlet of the valve body 13 respectively. Specifically, when the valve body 13 is not installed, the oil passage 101 can be straight and directly connected to the rod or rodless chamber. When the valve body 13 is installed, the oil needs to enter the valve body 13 through the first section 101a in the oil passage 101 for regulation before entering the rod or rodless chamber through the second section 101b. This allows the oil to be regulated by the valve body 13 before entering the cylinder 01, ensuring the stability of pressure and flow and improving the reliability of the deep-sea submersible oil pump cylinder integrated hydraulic press.

[0051] Based on the above embodiments, both seats 11 are provided with pressure measuring channels 103 that communicate with the oil passage 101. The pressure measuring channels 103 are arranged to pass through the side facing the pipe body 20, and pressure measuring connectors 14 are fixedly installed in the pressure measuring channels 103. By setting pressure measuring channels 103 on the seats 11 and fixing pressure measuring connectors 14 in the pressure measuring channels 103, pressure changes in the oil passage 101 can be monitored in real time, which helps to detect system abnormalities in a timely manner and avoid oil delivery failures caused by excessively high or low pressure. Specifically, the pressure measuring connectors 14 can be used with various pressure measuring devices, such as pressure gauges and pressure sensors, to meet different measurement needs and ensure measurement accuracy.

[0052] Based on the above embodiments, the line channel 102 includes a longitudinal section 102a and a transverse section 102b that are perpendicularly connected to each other. The port of the longitudinal section 102a is set towards the power unit, and the port of the transverse section 102b is set towards the pipe body 20 and is fixedly connected to the end of the pipe body 20. The longitudinal section 102a is directly connected to the line output end of the power unit to ensure that the connection line can be stably set in the line channel 102. Moreover, the vertical connection design reduces the detour of the line and reduces the line resistance and signal attenuation. The transverse section 102b is fixedly connected to the pipe body 20 to ensure that the connection line can be stably transported and assembled into the pipe body 20. The end of the pipe body 20 is fixedly connected to the port of the transverse section 102b to provide a certain support for the pipe connection and reduce the loosening of the connection caused by vibration or external force.

[0053] Based on the above embodiment, a clamping and fixing component 15 is installed on the side of the base 11 opposite to the tube 20. The end face of the tube 20 abuts against the port of the transverse section 102b, and the clamping and fixing component 15 is clamped on the outer axial surface of the tube 20. The design of the clamping and fixing component 15 makes the connection between the tube 20 and the base 11 more stable, reduces the risk of loosening due to vibration or external force, ensures the sealing of the line channel 102, and improves the stability of line transmission, especially suitable for long-term stable operation in deep water high-pressure environments. Moreover, the use of the clamping and fixing component makes the connection between the tube 20 and the base 11 more convenient, reduces the complexity of assembly and maintenance, and facilitates quick disassembly and replacement of the tube 20. Specifically, the clamping and fixing component 15 can be set as a clamp or a ring-shaped clamping block structure, which works in conjunction with the sealing structure to seal and reduce the interference and influence of the external environment on the electrical signal transmission in the line channel 102.

[0054] Based on the above embodiment, the outer side of the end of the tube body 20 protrudes to form a step portion 21, and the inner side of the clamping and fixing member 15 has an annular anti-detachment groove 15a, in which the step portion 21 is confined; the step portion 21 at the end of the tube body 20 cooperates with the annular anti-detachment groove 15a of the clamping and fixing member 15, restricting the axial and radial movement of the tube body 20, ensuring a more stable connection between the tube body 20 and the seat body 11; effectively preventing the connection from loosening due to external force or vibration in deep water and high pressure environment, further enhancing the sealing between the tube body 20 and the seat body 11, and reducing the risk of leakage due to loosening or deformation at the connection; specifically, the cross-sectional shape of the step portion 21 and the anti-detachment groove 15a can be set as a U-shaped, arc-shaped, or body-shaped connection form to further increase the anti-detachment tensile force and ensure the stability of the connection.

[0055] Based on the above embodiment, two inlet / outlet ports 11b are provided on the side of the base 11 away from the pipe body 20. The two inlet / outlet ports 11b are respectively connected to the longitudinal section 102a and the transverse section 102b, and a watertight cable connector 16 is fixedly installed on the outside of each inlet / outlet port 11b. The two inlet / outlet ports 11b can lead out the connecting lines in the pipe body 20 and the line channel 102, and are respectively connected to the longitudinal section 102a and the transverse section 102b, making the entry and exit of the lines more orderly, reducing the chaos and mutual interference of the lines, and improving the overall performance of the system. The watertight cable connector 16 installed on the outside of the inlet / outlet ports 11b can effectively prevent external moisture, impurities or high-pressure liquids from entering the line channel 102, further improving the sealing performance of the system and ensuring the stability of line transmission. Specifically, the watertight cable connector 16 can adopt the structure of a sealing sleeve or a sealing plug. There is no specific limitation here, as long as it can realize the entry and exit of the line and ensure the sealing effect.
