Description

Technical Field

[0001] This invention relates to the field of marine dual-interface observation buoy technology, specifically to a system and adjustment method for realizing the lifting and lowering motion of a marine dual-interface observation buoy. Background Technology

[0002] Currently, the ascent and descent of ocean buoys in the ocean are mainly achieved by controlling the volume of the oil bladder using a hydraulic system. With the buoy's mass remaining constant, increasing the oil bladder volume generates greater buoyancy; when the buoyancy exceeds the buoy's weight, the buoy can rise. Conversely, decreasing the oil bladder volume reduces buoyancy; when the buoyancy is less than the buoy's weight, the buoy can descend.

[0003] A hydraulic system typically includes a piston pump, an oil bladder, an oil reservoir, and multiple connecting lines between the oil reservoir and the oil bladder. The piston pump drives the hydraulic oil to flow through the multiple connecting lines to increase and / or decrease the volume of the oil bladder.

[0004] Current buoy hydraulic systems involve connecting pipelines that are installed within the confined space inside the buoy. The pipeline layout is complex and difficult to install. The pipelines are long and have many joints, resulting in low reliability of pipeline sealing and the risk of oil loss and leakage. In addition, the pipelines are usually external or distributed, resulting in a large overall size and space occupied by the hydraulic system. Summary of the Invention

[0005] The purpose of this invention is to provide a system and method for realizing the lifting and lowering movement of a marine dual-interface observation buoy. The lifting and lowering movement realization system of this invention integrates the connecting pipeline, one-way valve and solenoid valve in an integrated end cap, which makes the lifting and lowering movement realization system compact and concentrated, small in size, and occupies little internal space of the buoy. It can avoid the installation of intersecting pipelines in a narrow space and reduce the installation difficulty.

[0006] To address this, the present invention provides a system for realizing the lifting and lowering movement of a marine dual-interface observation buoy, comprising: a plunger mechanism, an oil storage tank, and an oil bladder; an integrated end cap, wherein the integrated end cap is provided with a pipeline connecting the plunger mechanism and the oil bladder, a pipeline connecting the plunger mechanism and the oil storage tank, and a pipeline connecting the oil bladder and the oil storage tank; a first one-way valve is provided on the pipeline connecting the plunger mechanism and the oil storage tank; a second one-way valve is provided on the pipeline connecting the plunger mechanism and the oil storage tank; and a solenoid valve is provided on the pipeline connecting the oil bladder and the oil storage tank.

[0007] In some embodiments of the present invention, an integrated tube is provided inside the integrated end cap, and the piston rod of the plunger mechanism is slidably fitted inside the integrated tube; when the piston rod moves upward, the first one-way valve closes, the second one-way valve opens, and the hydraulic oil in the oil storage tank is drawn into the integrated tube.

[0008] In some embodiments of the present invention, when the piston rod moves downward, the first one-way valve opens and the second one-way valve closes, and the hydraulic oil in the integrated pipe is pushed into the oil bladder.

[0009] In some embodiments of the present invention, when the solenoid valve is opened, the hydraulic oil in the oil bladder flows into the oil storage tank under the pressure difference between the external pressure of the seawater and the internal pressure of the buoy.

[0010] In some embodiments of the present invention, the connecting pipeline between the plunger mechanism and the oil bladder includes a first oil bladder tube communicating with the oil bladder, and the first one-way valve is disposed on the first oil bladder tube; the first oil bladder tube is connected to the integrated tube, and the first oil bladder tube and the integrated tube have the same axial direction.

[0011] In some embodiments of the present invention, the connecting pipeline between the plunger mechanism and the oil storage tank includes a first oil tank pipe communicating with the oil storage tank, and a second one-way valve is disposed on the first oil tank pipe; the first oil tank pipe and the integrated pipe are connected, and the axial directions of the first oil tank pipe and the integrated pipe are perpendicular to each other.

[0012] In some embodiments of the present invention, the connecting pipeline between the oil bladder and the oil storage tank includes a second oil bladder pipe connected to the oil bladder and a second oil storage tank pipe connected to the oil storage tank, both of which are connected to the solenoid valve.

[0013] In some embodiments of the present invention, the integrated end cap is provided with a mounting groove, and the solenoid valve is disposed in the mounting groove.

[0014] This invention also provides a method for adjusting the lifting and lowering motion of the aforementioned marine dual-interface observation buoy system. Methods to increase buoyancy include: The piston rod of the plunger mechanism is moved upward to close the first check valve and open the second check valve, so that the oil storage tank and the integrated pipe are connected, so that the hydraulic oil in the oil storage tank is drawn into the integrated pipe by the piston rod; The piston rod is controlled to move downward, opening the first one-way valve and closing the second one-way valve, so that the integrated pipe and the oil bladder are connected, so that the hydraulic oil in the integrated pipe is pushed into the oil bladder by the piston rod; Methods to adjust for decreased buoyancy include: The plunger mechanism is closed and the solenoid valve is opened, so that the hydraulic oil in the oil bladder flows into the oil storage tank under the action of the internal and external pressure difference.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are: This invention integrates all connecting pipes, the first one-way valve, the second one-way valve, and the solenoid valve into an integrated end cap, and places the integrated end cap between the plunger mechanism, the oil reservoir, and the oil bladder. This makes the overall structure of the lifting and lowering motion realization system of this invention compact and concentrated, with a small size and minimal space occupation within the buoy. The connecting pipes of this invention are not traditionally external or dispersed; their compact and concentrated layout shortens the oil transmission path and reduces oil loss and leakage risks.

[0016] The lifting motion system of the present invention does not require separate pipeline components. The oil bladder end cap and oil tank end cap of the present invention have built-in pipelines, which can avoid the layout and installation of pipelines in the narrow space inside the buoy, thereby reducing the installation difficulty and improving the installation efficiency.

[0017] Furthermore, only solenoid valves and / or check valves are needed to connect the pipeline between the oil bladder end cap and the oil tank end cap, eliminating the need for joint connections. This improves the sealing reliability of the pipeline and reduces oil loss and leakage risks.

[0018] The oil transmission path of this invention is short, which can improve the flow efficiency of hydraulic oil, thereby enabling rapid and flexible adjustment of the buoyancy of the float.

[0019] Other features and advantages of the present invention will become clearer after reading the detailed embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-15 As shown, the present invention provides a system for realizing the lifting and lowering motion of a marine dual-interface observation buoy. The system includes a plunger mechanism 10, an oil storage tank 20, and an oil bladder 30, with the oil bladder 30 located below the plunger mechanism 10 and the oil storage tank 20.

[0023] The plunger mechanism 10 includes a linear stepper motor, a lead screw drive assembly, and a piston rod 11. The linear stepper motor drives the lead screw drive assembly to move up and down by rotating forward and backward.

[0024] The plunger mechanism 10 can be any plunger mechanism commonly used in this technical field, and no specific limitations are made here.

[0025] The oil storage tank 20 is a sealed compartment. A sliding piston (not shown in the figure) is fitted at the rear of the oil storage tank 20. The oil pressure inside the oil storage tank 20 can be adjusted in real time by sliding the sliding piston.

[0026] The oil storage tank 20 can be any type of oil storage tank commonly used in this technical field, and no specific limitations are made here.

[0027] The oil bladder 30 can be made of corrosion-resistant composite materials commonly used in this technical field. The oil bladder 30 has a sealed cavity inside for storing hydraulic oil.

[0028] The marine dual-interface observation lifting and lowering buoy lifting and lowering motion realization system of the present invention also includes an integrated end cap, which is provided with a pipeline connecting the oil storage tank 20 and the plunger mechanism 10, a pipeline connecting the plunger mechanism 10 and the oil bladder 30, and a pipeline connecting the oil storage tank 20 and the oil bladder 30.

[0029] A first check valve 41 is provided on the connecting pipeline between the plunger mechanism 10 and the oil bladder 30, a second check valve 42 is provided on the connecting pipeline between the oil storage tank 20 and the plunger mechanism 10, and a solenoid valve 43 is provided on the connecting pipeline between the oil storage tank 20 and the oil bladder 30.

[0030] This invention, through the design and layout of the plunger mechanism 10, the oil storage tank 20, and the oil bladder 30, and by integrating all the connecting pipelines, the first one-way valve 41, the second one-way valve 42, and the solenoid valve 43 into the integrated end cap, enables the lifting and lowering motion realization system of this invention to have a compact and concentrated structure, small size, and small footprint inside the buoy. It avoids the installation of intersecting pipelines in a narrow space, has fewer pipeline joints, and high reliability of high-pressure pipeline sealing. It can also efficiently and quickly realize the adjustment of buoyancy and quickly and flexibly control the buoy's ascent and descent.

[0031] An integrated tube 12 is provided inside the integrated end cap, and the piston rod 11 of the plunger mechanism 10 can be slidably fitted inside the integrated tube 12; the axial direction of the piston rod 11 is the same as the axial direction of the float, and the axial direction of the piston rod 11 is the same as the axial direction of the integrated tube 12; the diameter of the piston rod 11 is smaller than the diameter of the integrated tube 12, and the piston rod 11 can move up and down inside the integrated tube 12.

[0032] The connecting pipeline between the plunger mechanism 10 and the oil bladder 30 includes a first oil bladder tube 31 that communicates with the oil bladder 30, and a first one-way valve 41 is disposed on the first oil bladder tube 31. The first oil bladder tube 31 is connected to the integrated tube 12, and the axial direction of the first oil bladder tube 31 is the same as that of the integrated tube 12.

[0033] In some embodiments of the present invention, the top of the first oil bladder tube 31 and the bottom of the integrated tube 12 are connected.

[0034] The connecting pipeline between the plunger mechanism 10 and the oil storage tank 20 includes a first oil tank pipe 21 that communicates with the oil storage tank 20, and a second one-way valve 42 is disposed on the first oil tank pipe 21. The first oil tank pipe 21 is connected to the integrated pipe 12, and the axial direction of the first oil tank pipe 21 is perpendicular to the axial direction of the integrated pipe 12.

[0035] In some embodiments of the present invention, the first oil tank pipe 21 is vertically connected to the side wall of the integrated pipe 12, and the interface of the first oil tank pipe 21 on the integrated pipe 12 is located below the lower limit position of the piston rod 11. That is, when the piston rod 11 moves down to the lowest position in the integrated pipe 12, the bottom of the piston rod 11 is higher than the interface of the first oil tank pipe 21 on the integrated pipe 21.

[0036] When the piston rod 11 of the plunger mechanism 10 moves upward, it can drive the first check valve 41 to close and the second check valve 42 to open. The hydraulic oil in the oil storage tank 20 can flow into the integrated pipe 12 through the first oil tank pipe 21 under the suction action of the piston rod 11.

[0037] When the piston rod 11 moves downward, it can drive the first check valve 41 to open and the second check valve 42 to close. By opening the first check valve 41, the hydraulic oil in the integrated pipe 12 can flow to the oil bladder 30 through the first oil bladder pipe 31 under the thrust of the piston rod 11, thereby increasing the volume of the oil bladder 30 and thus increasing the buoyancy of the float.

[0038] The connecting pipeline between the oil bladder 30 and the oil storage tank 20 includes a second oil bladder pipe 32 connected to the oil bladder 30 and a second oil tank pipe 22 connected to the oil storage tank 20. Both the second oil bladder pipe 32 and the second oil tank pipe 22 are connected to the solenoid valve 43.

[0039] When the solenoid valve 43 is opened, the hydraulic oil in the oil bladder 30 can flow to the oil storage tank 20 through the second oil bladder pipe 32 and the second oil tank pipe 22 under the action of the pressure difference inside and outside the buoy. This can reduce the volume of the oil bladder 30 and thus reduce the buoyancy of the buoy.

[0040] The integrated end cap includes an oil bladder end cap 50 and an oil tank end cap 60. The oil bladder end cap 50 and the oil tank end cap 60 can be two separate parts, or the oil bladder end cap 50 and the oil tank end cap 60 can be integrally formed by processing technology. No specific restrictions are made here.

[0041] In some embodiments of the present invention, the fuel bladder end cap 50 and the fuel tank end cap 60 are two separate components. The fuel bladder end cap 50 is a single piece, which can be integrally formed by a processing technology, and no specific limitations are imposed here. The fuel tank end cap 60 is also a single piece, which can be integrally formed by a processing technology, and no specific limitations are imposed here.

[0042] The oil bladder end cap 50 includes an oil bladder end cap 51 and an integrated oil passage stack 52 disposed above the oil bladder end cap 51. The oil bladder end cap 51 and the integrated oil passage stack 52 are integrally formed by processing technology.

[0043] The bottom cover 51 of the oil bladder is cylindrical in shape, and the top surface of the bottom cover 51 of the oil bladder is flat. The integrated oil circuit stack 52 of the oil bladder end cover is set on the top surface of the bottom cover 51 of the oil bladder. The integrated oil circuit stack 52 of the oil bladder end cover does not completely occupy the top surface of the bottom cover 51 of the oil bladder. The top surface of the bottom cover 51 of the oil bladder that is not occupied by the integrated oil circuit stack 52 of the oil bladder end cover forms an installation platform 55.

[0044] The bottom of the fuel tank end cap 60 abuts against the mounting platform 55, and the side of the fuel tank end cap 60 (the side of the fuel tank end cap 60 is flat) and the side of the fuel bladder end cap integrated fuel line stack 52 (the side of the fuel bladder end cap integrated fuel line stack 52 is flat) fit together. The fuel tank end cap 60 and the fuel bladder end cap integrated fuel line stack 52 can be connected together by bolts, so that the fuel tank end cap 60 and the fuel bladder end cap 50 can be assembled into an integrated end cap.

[0045] The oil bladder end cap 51 is connected to the oil bladder 30. In some embodiments of this application, the bottom of the oil bladder end cap 51 is provided with an end cap connecting part 53, and the top of the oil bladder 30 is provided with an oil bladder connecting part 33. The oil bladder connecting part 33 is sealed and connected inside the end cap connecting part 53, so that the oil bladder 30 and the oil bladder end cap 51 can be connected.

[0046] In some embodiments of the present invention, the oil bladder connecting part 33 protrudes from the top of the oil bladder 30 and is connected to the oil bladder 30; the end cap connecting part 53 can be a cavity recessed at the bottom of the oil bladder end cap 51, and the oil bladder connecting part 33 is sealed and fitted inside the end cap connecting part 53, so that the oil bladder 30 and the end cap connecting part 53 can be connected.

[0047] The top of the oil tank end cap 60 is provided with an oil tank connection portion 61, and the oil tank end cap 60 and the oil tank connection portion 61 are integral parts. The oil tank connection portion 61 extends into the oil storage tank 20 from the bottom opening, and the sealing end of the oil tank connection portion 61 is inside the bottom opening of the oil storage tank 20, thereby enabling a sealed connection between the top of the oil tank end cap 60 and the oil storage tank 20. The sealing connection method of the oil tank connection portion 61 within the bottom opening of the oil storage tank 20 can be a common connection method in this technical field, and no specific limitation is made here.

[0048] The integrated tube 12 is disposed inside the integrated oil passage stack 52 of the oil bladder end cap, with the opening of the integrated tube 12 facing upward. The plunger mechanism 10 is located above the integrated oil passage stack 52 of the oil bladder end cap, and the piston rod 11 of the plunger mechanism 10 extends into the integrated tube 12, and the piston rod 11 is slidably fitted inside the integrated tube 12.

[0049] The first oil bladder tube 31 extends downward from the bottom of the integrated tube 12, and the first oil bladder tube 31 and the integrated tube 12 are axially aligned. The oil bladder end cap 51 is provided with a first connecting tube 54, one end of the first connecting tube 54 is connected to the first oil bladder tube 31, and the other end of the first connecting tube 54 is connected to the end cap connecting part 53, thereby realizing the connection between the first oil bladder tube 31 and the oil bladder 30.

[0050] In some embodiments of the present invention, the bottom of the first oil bladder tube 31 is connected to a first mounting tube 311, and the bottom of the first mounting tube 311 is connected to a first connecting tube 54; the axial direction of the first mounting tube 311 is the same as the axial direction of the first oil bladder tube 31, and the radius of the first mounting tube 311 is greater than the radius of the first oil bladder tube 31.

[0051] The first one-way valve 41 includes a first spring 411 and a first valve ball 412, with the first valve ball 412 abutting against the top of the first spring 411; the first spring 411 and the first valve ball 412 are installed inside the first mounting tube 311, with the diameter of the first valve ball 412 being smaller than the diameter of the first mounting tube 311 and larger than the diameter of the first oil bladder tube 31.

[0052] When the piston rod 11 moves upward, the piston's suction action drives the first valve ball 412 upward, causing it to abut against the top of the first mounting tube 311. The first valve ball 412 then blocks the first oil bladder tube 31. At this time, the first check valve 41 is closed, effectively blocking the connection between the first oil bladder tube 31 and the first connecting tube 54. The first spring 411 provides support for the first valve ball 412, ensuring it can stably and effectively abut against the top of the first mounting tube 311, thus effectively blocking the first oil bladder tube 31.

[0053] When the piston rod 11 moves downward, the piston pushes the first valve ball 412 downward, causing it to disengage from the top of the first mounting tube 311 and no longer block the first oil bladder tube 31. At this time, the first one-way valve 41 is open, connecting the first oil bladder tube 31 and the first connecting tube 54, thus enabling communication between the first oil bladder tube 31 and the oil bladder 30.

[0054] The bottom of the oil bladder end cap 51 is provided with a second mounting tube 312, which can be an internally threaded tube. The second mounting tube 312 is connected to the first mounting tube 311, and the second mounting tube 312 and the first mounting tube 311 are axially aligned. During installation, the first spring 411 and the first valve ball 412 are inserted into the first mounting tube 311 through the second mounting tube 312, and then a fastening bolt 313 is connected inside the second mounting tube 312. The bottom of the first spring 411 abuts against the fastening bolt 313, thereby allowing the first one-way valve 41 to be installed inside the first mounting tube 311.

[0055] The first oil tank pipe 21 extends from the side wall of the integrated pipe 12 toward the side of the integrated oil passage stack 52 of the oil sac end cap, and the first oil tank pipe 21 and the integrated pipe 12 are perpendicular in axis. A second connecting pipe 62 is provided inside the oil tank end cap 60. One end of the second connecting pipe 62 extends toward the oil tank connection part 61, and the opening of one end of the second connecting pipe 62 is located on the top surface of the oil tank connection part 61, so that the second connecting pipe 62 is connected to the oil storage tank 20; the opening of the other end of the second connecting pipe 62 is located on the side of the oil tank end cap 60, and the opening of the other end of the second connecting pipe 62 is connected to the first oil tank pipe 21, so that the first oil tank pipe 21 and the second connecting pipe 62 are connected to each other, thereby realizing the connection between the first oil tank pipe 21 and the oil storage tank 20.

[0056] In some embodiments of the present invention, one end of the first oil tank pipe 21 is connected to the integrated pipe 12, and the other end of the first oil tank pipe 21 is connected to the third mounting pipe 211, the radius of the third mounting pipe 211 being larger than the radius of the first oil tank pipe 21; one end of the second connecting pipe 62 is connected to the oil storage tank 20, and the other end of the second connecting pipe 62 is connected to the fourth mounting pipe 212, the radius of the fourth mounting pipe 212 being larger than the radius of the second connecting pipe 62; the first oil tank pipe 21, the third mounting pipe 211, and the fourth mounting pipe 212 are axially aligned; when the side of the oil tank end cap 60 and the side of the oil bladder end cap integrated oil passage stack 52 are properly fitted together, the third mounting pipe 211 and the fourth mounting pipe 212 can be connected to each other, thereby enabling the first oil tank pipe 21 and the second connecting pipe 62 to be connected.

[0057] The second one-way valve 42 includes a second spring 421 and a second valve ball 422, the second valve ball 422 abutting against the end of the second spring 421. Figure 12 As shown, the second valve ball 422 abuts against the left end of the second spring 421; the second spring 421 and the second valve ball 422 are installed inside the third mounting pipe 211 and the fourth mounting pipe 212, with the second spring 421 close to the first oil tank pipe 21 and the second valve ball 422 close to the second connecting pipe 62; the diameter of the second valve ball 422 is smaller than the diameter of the fourth mounting pipe 212 and larger than the diameter of the second connecting pipe 62.

[0058] like Figure 11 , Figure 12 As shown, when the piston rod 11 moves upward, under the suction action of the piston, the second valve ball 422 can be driven to move to the right, so that the second valve ball 422 is disengaged from the left end of the fourth mounting pipe 212. The second valve ball 422 does not block the second connecting pipe 62 (the second one-way valve 42 is in the open state), and the first oil tank pipe 21 and the second connecting pipe 62 can be connected, thereby realizing the connection between the integrated pipe 12 and the oil storage tank 20.

[0059] When the piston rod 11 moves downward, under the action of the piston, it can drive the second valve ball 422 to move to the left, so that the second valve ball 422 can move to the left end of the fourth mounting pipe 212. The second valve ball 422 abuts against the left end of the fourth mounting pipe 212, and the second valve ball 422 can block the second connecting pipe 62 (the second one-way valve 42 is in the closed state), which can isolate and block the connection between the first oil tank pipe 21 and the second connecting pipe 62.

[0060] During installation, the second spring 421 and the second valve ball 422 are inserted into the third mounting pipe 211 and / or the fourth mounting pipe 212. The oil tank end cap 60 is placed on the mounting platform 55, and the side of the oil tank end cap 60 and the side of the oil bladder end cap integrated oil passage stack 52 are fitted together. Then, the oil tank end cap 60 and the oil bladder end cap integrated oil passage stack 52 are connected by multiple bolts, so that the oil tank end cap 60 and the oil bladder end cap 50 can be assembled into an integrated end cap. At the same time, the third mounting pipe 211 and the fourth mounting pipe 212 can be connected, so that the second one-way valve 42 can be installed in the third mounting pipe 211 and the fourth mounting pipe 212.

[0061] The oil tank end cap 60 has a recessed mounting groove 63, and the solenoid valve 43 is installed in the mounting groove 63. The installation method can be a common installation method in this technical field, and no specific limitation is made here. By installing the solenoid valve 43 in the recessed mounting groove 63, the solenoid valve 43 can be concealed and avoid protrusion. This allows the marine dual-interface observation lifting and lowering buoy system to be small in size and compact in structure.

[0062] like Figure 4 , Figure 5As shown, the mounting groove 63 is an opening groove recessed on the side wall of the oil tank end cover 60, and the mounting groove 63 and the oil tank end cover 60 are arranged opposite each other on the side that fits into the integrated oil passage stack 52 of the oil bladder end cover. No specific restrictions are made here.

[0063] The second oil tank pipe 22 is installed inside the oil tank end cap 60. One end of the second oil tank pipe 22 is connected to the solenoid valve 43. The other end of the second oil tank pipe 22 is located on the top surface of the oil tank connection part 61, so that the second oil tank pipe 22 is connected to the oil storage tank 20.

[0064] The second oil bladder tube 32 includes a second oil bladder main tube 321 disposed inside the oil tank end cap 60 and a second oil bladder secondary tube 322 disposed inside the oil bladder end cap 50; one end of the second oil bladder main tube 321 is connected to the solenoid valve 43, and the other end opening of the second oil bladder main tube 321 is located on the side of the oil tank end cap 60; one end of the second oil bladder secondary tube 322 is connected to the end cap connection part 53, and the other end opening of the second oil bladder secondary tube 322 is located on the side of the integrated oil passage stack 52 of the oil bladder end cap; the other end opening of the second oil bladder main tube 321 and the other end opening of the second oil bladder secondary tube 322 are connected to each other, so that the second oil bladder main tube 321 and the second oil bladder secondary tube 322 are connected, that is, the second oil bladder tube 32 and the oil bladder 30 are connected.

[0065] like Figure 5 As shown, the oil tank end cap 60 is also provided with a connecting groove 64, which is connected to the mounting groove 63; the solenoid valve 43 is installed in the mounting groove 63, and the connecting end 431 of the solenoid valve 43 is fitted into the connecting groove 64. One end of the second oil tank pipe 22 is connected to the connecting groove 64, and the other end of the second oil tank pipe 22 is connected to the connecting end 431. One end of the second oil bladder main pipe 321 is connected to the connecting groove 64, and the other end of the second oil bladder main pipe 321 is connected to the connecting end 431.

[0066] The lifting motion system of the present invention does not require separate pipeline components. The oil bladder end cap and oil tank end cap of the present invention have built-in pipelines, which are formed during the processing of the oil bladder end cap and oil tank end cap. The specific processing technology can be a common technology in this field and is not specifically limited here.

[0067] This invention avoids the need for piping layout and installation within the confined space inside the buoy, reducing installation difficulty and improving efficiency. Furthermore, only solenoid valves and / or check valves are required between the pipes of the oil bladder end cap and the oil tank end cap, eliminating the need for joint connections and improving the sealing reliability of the piping.

[0068] The marine dual-interface observation buoy lifting and lowering motion realization system of the present invention can realize the rapid flow of hydraulic oil, thereby enabling efficient and quick buoyancy adjustment and rapid and flexible control of the buoy's rising and falling motion.

[0069] By controlling the flow of hydraulic oil into the oil bladder 30, the volume of the oil bladder 30 can be expanded, and the buoyancy of the buoy can be increased; by controlling the flow of hydraulic oil from the oil bladder 30 to the oil storage tank 20, the volume of the oil bladder 30 can be reduced, and the buoyancy of the buoy can be decreased.

[0070] The adjustment method of the marine dual-interface observation lifting and lowering buoy system of the present invention includes a method for increasing buoyancy. The present invention increases the buoyancy by pushing oil into the oil bladder 30 (introducing hydraulic oil into the oil bladder 30). Specifically: When the piston rod 11 moves upward, it can drive the first one-way valve 41 to close and the second one-way valve 42 to open, allowing the hydraulic oil in the oil storage tank 20 to flow into the integrated pipe 12 through the second connecting pipe 62 and the first oil tank pipe 21. When the piston rod 11 moves downward, it can drive the first one-way valve 41 to open and the second one-way valve 42 to close; the opening of the first one-way valve 41 allows the hydraulic oil in the integrated pipe 12 to flow into the oil bladder 30 through the first oil bladder pipe 31 and the first connecting pipe 54, causing the oil bladder 30 to expand and the buoyancy of the float to increase.

[0071] The adjustment method of the marine dual-interface observation lifting and lowering buoy system of the present invention includes a method for reducing buoyancy. The present invention reduces the buoyancy of the marine buoy by returning oil to the oil storage tank 20 (injecting hydraulic oil into the oil storage tank 20). Specifically: When the plunger mechanism 10 is closed and the solenoid valve 43 is opened, a large amount of hydraulic oil in the oil storage tank 20 has flowed into the oil bladder 30 during the oil filling stage, thus creating a negative pressure inside the buoy. Under the action of external atmospheric and seawater pressure, the hydraulic oil in the oil bladder 30 can flow back into the oil storage tank 20 through the second oil bladder pipe 32 and the second oil tank pipe 22, thereby reducing the volume of the oil bladder 30 and decreasing the buoyancy of the buoy.

[0072] The marine dual-interface observation lifting and lowering buoy lifting and lowering motion realization system of this application also includes a buoy shell 70, a plunger mechanism 10, an oil storage tank 20, an oil bladder end cap 50 and an oil tank end cap 60 installed inside the buoy shell 70, and an oil bladder 30 located below the buoy shell 70.

[0073] This invention integrates all pipelines, check valves, and solenoid valves into an integrated end cap. The pipelines are not traditionally external or scattered, but rather compact and centralized, which reduces the overall volume and space occupied, while shortening the oil transmission path and reducing oil loss and leakage risks.

[0074] The oil transmission path of the present invention is short. The piston mechanism 10, the one-way valve and the solenoid valve cooperate with each other to achieve stable flow of hydraulic oil and rapid switching of hydraulic oil flow direction. It can increase the flow rate of hydraulic oil per minute, increase the single push volume of piston rod 11 and the number of reciprocating strokes of piston rod 11 per minute, thereby enabling rapid and flexible adjustment of buoyancy of the float.

[0075] Calculations show that in this invention, the single-stroke oil displacement volume of the piston rod 11 is 1000-1010 mm. 3 The piston rod 11 reciprocates 30-35 times per minute, and the hydraulic oil flow rate is 30-35 ml per minute. Specifically, the single thrust volume of the piston rod 11 is 1005.309649 mm². 3 The piston rod 11 reciprocates 32.3166 times per minute, and the hydraulic oil flow rate is 32.4882 ml per minute.

[0076] In some embodiments of the present invention, the volume of the integrated tube 12 is greater than the single-push volume of the piston rod 11.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
