Description

Technical Field

[0001] This invention belongs to the field of marine exploration technology, specifically relating to an auxiliary tool for disassembling and assembling marine acoustic transponders. Background Technology

[0002] The development of marine oil and gas resources is a current hot topic and focus of the world's marine economy. Marine oil and gas resources are not only abundant, but modern science and technology have also given us the ability to develop them. The marine oil and gas industry has developed into a new and high-value leading industry in the marine economy.

[0003] Currently, marine seismic exploration involves artificially generating seismic waves, which are then reflected by the strata and received by submarine cables or submarine nodes. Both require a positioning system to reach their designated locations, and the accompanying marine acoustic transponder can perform positioning and ranging calculations to effectively locate the submarine cables and submarine nodes.

[0004] Marine acoustic transponders in related technologies typically include a transponder body, an outer casing, and a clamping plate. The transponder body is movably inserted into the outer casing. The clamping plate is arc-shaped and has a limiting plate at its center. The upper end of the outer casing has a limiting hole and two mounting holes. The limiting plate can be engaged with the limiting hole, and both ends of the clamping plate are located in corresponding mounting holes, allowing the clamping plate to clamp and fix the transponder body. A limiting screw is threaded onto the clamping plate, and the top of the transponder body has a limiting groove for the limiting screw to engage with the threaded screw, thus connecting the clamping plate to the transponder body. Simultaneously, the upper and lower ends of the outer casing have positioning ring grooves to allow the outer casing to be positioned and engaged with external components.

[0005] The transponder body includes a support cylinder. A sealing seat is threaded to the bottom of the support cylinder, and an inner plug is inserted into the top. The inner plug is interference-fitted with the support cylinder, and a limiting groove is provided on the inner plug. A circuit board is vertically mounted inside the support cylinder. A clamping ring is movably mounted at the top of the support cylinder to press the circuit board, and the inner plug can clamp and fix the clamping ring. Simultaneously, the clamping ring has two limiting notches, and the two sides of the top of the circuit board can respectively engage with the corresponding limiting notches to achieve circuit board positioning.

[0072] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be arbitrarily combined with each other.

[0073] like Figure 1 , Figure 2As shown, marine acoustic transponders in related technologies typically include a transponder body 100, an outer casing 200, and a clamping plate 300. The transponder body 100 is movably inserted into the outer casing 200, and the clamping plate 300 is used to clamp and fix the transponder body 100. The clamping plate 300 is arc-shaped, and a limiting plate 301 is integrally formed at the middle position of the clamping plate 300. The upper end of the outer casing 200 is provided with a limiting hole 201 and two mounting holes 202. The limiting plate 301 can be inserted into the limiting hole 201, and the two ends of the clamping plate 300 are respectively located in the corresponding mounting holes 202, so that the clamping plate 300 can clamp and fix the transponder body 100.

[0074] like Figure 1 , Figure 2 As shown, a limiting screw 302 is threadedly connected to the clamping plate 300, and a limiting groove 101 is provided on the top of the transponder body 100 for threaded engagement of the limiting screw 302, so as to realize the connection between the clamping plate 300 and the transponder body 100. At the same time, positioning ring grooves 203 are respectively provided at the upper and lower ends of the outer casing 200, so that the outer casing 200 can be positioned and engaged with the outer component.

[0075] like Figure 1 , Figure 2 As shown, the transponder body 100 includes a support cylinder 102. A sealing seat 103 is threadedly connected to the bottom of the support cylinder 102, and an inner hole plug 104 is inserted into the top. The inner hole plug 104 is interference-fitted with the support cylinder 102, and a limiting groove 101 is provided on the inner hole plug 104. A circuit board 105 is vertically arranged inside the support cylinder 102. A clamping ring 106 for pressing the circuit board 105 is movably arranged at the top of the support cylinder 102, and the inner hole plug 104 can press and fix the clamping ring 106. Simultaneously, two limiting notches 107 are provided on the clamping ring 106, and the two sides of the top of the circuit board 105 can respectively engage into the corresponding limiting notches 107 to achieve positioning of the circuit board 105.

[0076] like Figures 3 to 14 The figure shown is an embodiment of the present invention. This embodiment discloses an auxiliary disassembly and assembly tool for a marine acoustic transponder, including an outer casing disassembly and assembly part 1 and a transponder body disassembly and assembly part 2. The outer casing disassembly and assembly part 1 is used to disassemble and assemble the outer casing 200, and the transponder body disassembly and assembly part 2 is used to disassemble and assemble the transponder body 100.

[0077] In one embodiment, such as Figure 3 , Figure 4 , Figure 5As shown, the outer casing assembly / disassembly unit 1 includes a positioning seat 11 and a pusher 12. The positioning seat 11 is used to place the transponder on an external platform, and the bottom of the acoustic transponder can be inserted into the positioning seat 11 to keep the acoustic transponder vertical, thereby fixing the acoustic transponder and facilitating the assembly / disassembly of the limit screw 302 and the clamping plate 300. The pusher 12 can abut against the transponder body 100, and the pusher 12 is used to push the transponder body 100 out of the outer casing 200 or push the transponder body 100 into the outer casing 200, thereby realizing the assembly / disassembly of the outer casing 200.

[0078] In one embodiment, such as Figure 5 As shown, a flexible shock absorber 13 is fixedly connected to the bottom of the jacking column 12. The shock absorber 13 can be placed on the external platform and keep the jacking column 12 vertical. When disassembling the outer casing 200, the transponder body 100 can be aligned with the jacking column 12, and then the acoustic transponder can be controlled to move downward, causing the jacking column 12 to impact the transponder body 100, thereby pushing the transponder body 100 out. The shock absorber 13 can provide good cushioning and energy absorption, preventing the jacking column 12 from rigidly impacting the external platform, thereby reducing the risk of damage to the external platform or the jacking column 12.

[0079] In one embodiment, such as Figure 3 , Figure 4 As shown, the positioning base 11 includes a vertically arranged positioning cylinder 111 and a limiting cylinder 112. The limiting cylinder 112 is coaxially arranged inside the positioning cylinder 111 and is fixedly connected to the positioning cylinder 111. Meanwhile, the top of the limiting cylinder 112 is integrally formed with a limiting inclined surface 113. When the top or bottom of the outer protective cylinder 200 is inserted into the positioning cylinder 111, the inclined surface at the top or bottom of the outer protective cylinder 200 can tightly abut against the limiting inclined surface 113, thereby achieving stable support for the outer protective cylinder 200.

[0080] In one embodiment, such as Figure 5 As shown, the outer casing disassembly unit 1 also includes a hammer 14 and a threaded post 15. The hammer head of the hammer 14 is used to strike the transponder body 100 to loosen the transponder body 100 and the outer casing 200. The threaded post 15 is fixed to the top of the hammer rod of the hammer 14, and the threaded post 15 can be threaded into the limiting groove 101 so that the operator can pull the transponder body 100 out of the outer casing 200 or push the transponder body 100 into the outer casing 200 using the hammer 14.

[0081] Since acoustic transponders are placed underwater for a long time, mud, sand and marine organisms can easily fill the gap between the transponder body 100 and the outer casing 200. If the transponder body 100 cannot be pushed out of the outer casing 200 by the pusher 12, the hammer head of the hammer 14 can be used to strike the transponder body 100 to loosen the transponder body 100 and the outer casing 200. Then the pusher 12 can be used to push the transponder body 100 out of the outer casing 200. Alternatively, the threaded post 15 can be threaded into the limiting groove 101, and the transponder body 100 can be pulled out of the outer casing 200 by pulling the hammer 14.

[0082] In one embodiment, such as Figure 7 , Figure 8 As shown, the outer casing assembly / disassembly unit 1 also includes a puller seat 16 and a multi-claw puller 17. The puller seat 16 is used to fit onto the outer casing 200 and forms a positioning engagement with one of the positioning ring grooves 203. The multi-claw puller 17 is used in conjunction with the puller seat 16. The multiple positioning hooks of the multi-claw puller 17 can be hooked and fixed with the puller seat 16 respectively, and the push rod of the multi-claw puller 17 can push the transponder body 100 out of the outer casing 200 or push the transponder body 100 into the outer casing 200.

[0083] If striking the transponder body with the hammer head of the hammer 14 fails to loosen the transponder body and outer casing, the puller seat 16 can be fitted onto the lower end of the outer casing, and the puller seat 16 can be positioned to engage with the positioning ring groove at the lower end. Then, the multiple positioning hooks of the multi-jaw puller 17 are hooked and fixed to the puller seat 16, and the push rod of the multi-jaw puller 17 abuts against the transponder body. At this point, the hydraulic control unit of the multi-jaw puller 17 drives the push rod to move, and the push rod then pushes the transponder body out of the outer casing.

[0084] In one embodiment, such as Figure 9 , Figure 10 As shown, the puller seat 16 includes an annular receiving seat 161, which can be fitted onto the outer protective sleeve 200. The top of the receiving seat 161 is provided with multiple puller grooves 162, which are evenly spaced along the circumference of the receiving seat 161. Multiple positioning hooks of the multi-claw puller 17 can be respectively engaged into the corresponding puller grooves 162. Simultaneously, the bottom of each puller groove 162 is provided with a positioning inclined surface 163, which matches the positioning hooks of the multi-claw puller 17 to achieve a tight hook-and-loop engagement between the multi-claw puller 17 and the receiving seat 161.

[0085] In this embodiment, six puller grooves 162 are provided, and the multi-claw puller 17 adopts a three-claw puller. Of course, in other embodiments, the multi-claw puller 17 can also adopt a four-claw puller. The number of puller grooves 162 can be set according to the number of positioning hooks of the multi-claw puller 17.

[0086] In one embodiment, such as Figure 9 , Figure 10 As shown, the inner wall of the receiving seat 161 is provided with a plurality of support holes 164, which are arranged at equal intervals along the circumference of the receiving seat 161. Each support hole 164 is slidably connected to a limit block 165, and each support hole 164 is provided with a control spring 166. The limit block 165 can slide radially along the receiving seat 161, and the control spring 166 is used to push the corresponding limit block 165 toward the center position of the receiving seat 161, and to make the limit block 165 engage in the positioning ring groove 203.

[0087] In one embodiment, such as Figure 1 , Figure 2 As shown, the thickness of the limiting block 165 is the same as the width of the positioning ring groove 203, so that the limiting block 165 can be tightly engaged with the positioning ring groove 203. At the same time, each limiting block 165 is provided with a guide slope 167 at its upper end. Under the action of the guide slope 167 and the outer protective sleeve 200, the limiting block 165 can move towards the outer edge of the receiving seat 161, so that the receiving seat 161 can be smoothly fitted onto the outer protective sleeve 200.

[0088] When the transponder body 100 needs to be disassembled, the receiving seat 161 is fitted onto the bottom of the outer casing 200, and the receiving seat 161 is pushed upward. When the limiting block 165 aligns with the positioning ring groove 203 at the lower end, multiple control springs 166 push the corresponding limiting blocks 165 to move, causing the multiple limiting blocks 165 to respectively engage in the positioning ring groove 203. Then, the multi-claw puller 17 can be installed, ensuring that the positioning hook of the multi-claw puller 17 engages in the corresponding puller groove 162, and that the positioning hook of the multi-claw puller 17 abuts against the positioning inclined surface 163. Then, the transponder body 100 can be pushed out using the push rod of the multi-claw puller 17. Afterward, the multi-claw puller 17 is disassembled, and the receiving seat 161 is pushed upward until it separates from the outer casing 200.

[0089] Similarly, when the transponder body 100 needs to be installed, the receiving seat 161 is placed on top of the outer casing 200, and the receiving seat 161 is pushed downwards. When the limiting block 165 aligns with the positioning ring groove 203 at the upper end, multiple control springs 166 push the corresponding limiting blocks 165 to move, causing the multiple limiting blocks 165 to respectively engage in the positioning ring groove 203. Subsequently, the bottom of the transponder body 100 is inserted into the outer casing 200, and the multi-claw puller 17 is installed. The transponder body 100 is pushed into the outer casing 200 by the push rod of the multi-claw puller 17. Then, the multi-claw puller 17 is disassembled, and the receiving seat 161 is pushed downwards until the receiving seat 161 separates from the outer casing 200.

[0090] In one embodiment, such as Figure 9 , Figure 10 As shown, the receiving seat 161 includes a receiving ring 168, a support ring 169, and a mounting ring 170. The support ring 169 is coaxially fixed to the top of the receiving ring 168, and the inner diameter of the support ring 169 is equal to the inner diameter of the receiving ring 168. The mounting ring 170 has an inverted L-shaped cross-section, and multiple puller grooves 162 are respectively provided on the top of the mounting ring 170. The bottom of the mounting ring 170 is threaded to the receiving ring 168, and the top is threaded to the support ring 169, forming a support ring cavity 171 between the receiving ring 168, the support ring 169, and the mounting ring 170. Meanwhile, multiple support holes 164 are respectively provided through the support ring 169, and the multiple support holes 164 communicate with the support ring cavity 171.

[0091] In one embodiment, such as Figure 9 , Figure 10 As shown, a plurality of support screws 172 are threaded onto the mounting ring 170. One end of a plurality of control springs 166 is respectively sleeved on the corresponding support screw 172, and the other end is respectively fixedly connected to the corresponding limit block 165. At the same time, each limit block 165 has a stepped surface 173 at the end near the corresponding support screw 172, and a stepped groove 174 is provided at the ends of the plurality of support holes 164 that are far apart from each other. The stepped surface 173 can form a limiting fit with the corresponding stepped groove 174, thereby limiting the maximum sliding stroke of the limit block 165 and preventing the limit block 165 from sliding out of the corresponding support hole 164.

[0092] In one embodiment, such as Figure 11 , Figure 12 , Figure 13 , Figure 14As shown, the transponder body disassembly and assembly section 2 includes a disassembly pry bar 21, a clamping ring installer 22, and a pry fork 23. The pry fork 23 is used to pry the piston on the inner hole plug 104, so that the gas inside the transponder body 100 can be discharged, that is, to "vent" the transponder body 100. The tip of the disassembly pry bar 21 can be inserted into the gap between the inner hole plug 104 and the support cylinder 102, so that the operator can use the disassembly pry bar 21 to pry out the inner hole plug 104. The clamping ring installer 22 is used to install the clamping ring 106 and ensure that the two sides of the top of the circuit board 105 are respectively engaged in the corresponding limiting notches 107. In addition, the disassembly pry bar 21 can also be inserted into the limiting hole 201 and push the limiting plate 301 out of the limiting hole 201, so as to facilitate the operator to disassemble the clamping plate 300, thereby increasing the functionality of the disassembly pry bar 21.

[0093] In one embodiment, such as Figure 13 , Figure 14 As shown, the clamping ring installer 22 includes a mounting handle 221. A guide post 222 is coaxially fixedly connected to the bottom of the mounting handle 221. The outer diameter of the guide post 222 matches the inner diameter of the support cylinder 102, and the guide post 222 is used to push the clamping ring 106 to move, so that the clamping ring 106 smoothly enters the support cylinder 102. An installation inclined surface 223 is integrally formed at the bottom edge of the guide post 222, and the installation inclined surface 223 matches the inclined surface at the top of the clamping ring 106 to improve the limiting effect between the clamping ring 106 and the guide post 222, so as to avoid the clamping ring 106 from lifting.

[0094] In one embodiment, such as Figure 13 , Figure 14 As shown, a mounting block 224 is fixedly connected to the center of the bottom of the guide post 222. The mounting block 224 is provided with a clamping groove 225, and the top of the circuit board 105 can enter the clamping groove 225. At the same time, two limiting strips 226 are fixedly connected to the bottom of the guide post 222. The two limiting strips 226 are symmetrically distributed on both sides of the mounting block 224, and the two limiting strips 226 can be respectively engaged in the corresponding limiting notches 107, thereby realizing the positioning of the clamping ring 106.

[0095] In one embodiment, such as Figure 1 , Figure 2 As shown, the inner walls on both sides of the clamping groove 225 are inclined, and the opening of the clamping groove 225 is flared. The bottom width of the clamping groove 225 is the same as the thickness of the circuit board 105, so that the top of the circuit board 105 can be tightly inserted into the clamping groove 225, thereby limiting the installation position of the circuit board 105.

[0096] When installing circuit board 105, insert circuit board 105 into support cylinder 102, then place clamping ring 106 on guide post 222, and engage the two limiting strips 226 into their respective limiting notches 107. Next, align clamping groove 225 with circuit board 105, and use installation handle 221 to move guide post 222 and clamping ring 106, causing positioning ring 106 to enter support cylinder 102. During this process, circuit board 105 is straightened by the guidance of the inner walls on both sides of clamping groove 225. When the top of circuit board 105 engages in clamping groove 225, and the two sides of the top of circuit board 105 engage in their respective limiting notches 107, circuit board 105 is now in place. Then, guide post 222 can be removed from support cylinder 102, and inner hole plug 104 can be installed.
