[0051] The embodiment of the present application provides a water bird positioning pin disassembly device. Figure 1 、 2 As shown in Figures 7 to 10, in some embodiments, the water bird locating pin disassembly device includes: a support member 10, having a U-shaped accommodating space, and the water bird body is embedded in the U-shaped accommodating space; a first base 20, connected to one end of the support member 10, and a groove 202 is provided on the first base 20, and the groove 202 is sleeved on the first end 601 of the locating pin 60, and the first end 601 is sunk into the groove 202 when subjected to a lateral force; a second base, connected to the other end of the support member 10, and a through hole 301 is provided on the second base 30; a threaded sleeve 40, connected to the through hole 301; a screw 50, connected to the threaded sleeve 40, the screw 50 can abut against the second end 602 of the locating pin 60, and the center of the groove 202 is coaxial with the through hole 301, the threaded sleeve 40, and the screw 50; during transmission, the front end of the screw 50 abuts against the second end 602 and applies lateral pressure, and causes the first end 601 to sink into the groove 202.

[0052] The waterfowl locating pin disassembly device provided in the embodiment of the present application is designed with a support member 10 having a U-shaped accommodating space, so that the waterfowl body 80 can be embedded in the U-shaped accommodating space during use, thereby providing a stable clamping force for the waterfowl body 80, and thus providing a stable support for the waterfowl body 80. Moreover, in the embodiment of the present application, a groove 202 is provided on the first base 20, which is clamped on the first end 601 of the locating pin 60, thereby providing a stable support force for the locating pin 60. At the same time, the center of the groove 202, the through hole 301 on the second base 30, the threaded sleeve 40, and the screw 50 are designed to be coaxial, so that the locating pin 60 and the screw 50 maintain concentricity, so that during the disassembly process, the screw 50 can apply stable pressure to the first end 601 of the locating pin 60, so that the first end 601 of the locating pin 60 smoothly passes through the waterfowl body 80, which can effectively prevent the waterfowl body 80 and the locating pin 60 from being deformed or even damaged.

[0053] In other embodiments of the present application, the shape of the accommodation space of the support member 10 can also be other shapes, for example, a rectangular accommodation space, depending on the outer shell shape of the water bird body 80. Therefore, in the present application, the shape of the accommodation space of the support member 10 can be adapted to the outer shell shape of the water bird body 80.

[0054] like Figure 3As shown, in some embodiments, the support member 10 includes a support body 101 and a first extension section 102 and a second extension section 103 connected to the ends of the support body 101. The support body 101, the first extension section 102, and the second extension section 103 form a U-shaped accommodation space. In the embodiment of the present application, the segmented design of the support member 10 can effectively accommodate the water bird body 80 within the U-shaped space, providing a stable clamping force for the water bird body 80. At the same time, the segmented design of the support member 10 allows the support member 10 to be smoothly disassembled and stored in sections when not in use, which is convenient for use and storage in narrow spaces at sea.

[0055] In the embodiment of the present application, since the application environment is relatively harsh and it is often necessary to use it in a position that is in contact with or immersed in seawater, the bracket body 101, the first extension section 102 and the second extension section 103 are all made of rigid materials, and are all made of corrosion-resistant rigid materials, so that the support member 10 as a whole has sufficient strength and rigidity, as well as corrosion resistance; preferably, the bracket body 101, the first extension section 102 and the second extension section 103 are all made of 316L stainless steel.

[0056] like Figure 3 As shown, in some embodiments, the first extension section 102 and the second extension section 103 are parallel to each other, so that the water bird body 80 can be more smoothly inserted into the U-shaped accommodation space, thereby preventing wear between the outer shell of the water bird body 80 and the first extension section 102 or the second extension section 103. In some embodiments of the present application, the first extension section 102 and the second extension section 103 are respectively detachably connected to the ends of the bracket body 101, thereby facilitating the disassembly of the support member 10 in sections.

[0057] like Figure 4 、 8(a) As shown in Figures 8(b), in some embodiments, a protrusion 201 is provided on the first base 20, and a groove 202 is provided on the protrusion 201. The shape of the groove 202 is adapted to the shape of the first end portion 601, so that the groove 202 can be well sleeved on the first end portion 601 during the disassembly process. In the embodiment of the present application, the inner diameter of the groove 202 is larger than the outer diameter of the first end portion 601, so that the first end portion 601 can be well sleeved in the groove 202 and can be well sunk into the groove 202 under a lateral force. In the embodiment of the present application, the diameter of the groove 202 can be the same as the diameter of the first end portion 601.

[0058] In the embodiment of the present application, the first base 20 and the protrusion 201 are both made of corrosion-resistant rigid materials; preferably, the first base 20 and the protrusion 201 are both made of 316L stainless steel.

[0059] like Figure 5As shown, in some embodiments, the second base 30 is provided with a through hole 301, so that the threaded sleeve 40 is inserted into the through hole 301. In other embodiments, in order to facilitate disassembly of the entire device structure, the threaded sleeve 40 may be provided with an external thread, and the inner wall of the through hole 301 may be provided with an internal thread, so that the threaded sleeve 40 is detachably connected to the through hole 301 through the thread.

[0060] In some embodiments of the present application, in order to enable the disassembly device structure to be well disassembled and stored, the first extension section 102 and the first base 20 can also be designed to be detachably connected, and the second extension section 103 and the second base 30 can be designed to be detachably connected; for example, the first extension section 102 and the first base 20 can be threadedly connected, and the second extension section 103 and the second base 30 can be threadedly connected.

[0061] like Figure 6 and 7 As shown, in some embodiments, the threaded sleeve 40 is provided with an internal thread 401 , and the screw rod 50 is provided with an external thread 501 , so that the screw rod 50 is transmission-connected to the threaded sleeve 40 through the thread.

[0062] In the embodiment of the present application, the second base 30 , the threaded sleeve 40 and the screw 50 are all made of corrosion-resistant rigid materials; preferably, the second base 30 , the threaded sleeve 40 and the screw 50 are all made of stainless steel.

[0063] like Figures 7 to 10 As shown, under the action of torsion, the screw 50 can rotate clockwise or counterclockwise in the threaded sleeve 40, causing the front end of the screw 50 to abut against the second end 602 of the positioning pin 60, or to withdraw from the second end 602. Moreover, the arrangement of the threaded sleeve 40 ensures that the screw 50 always maintains good concentricity with the center of the groove 202 during rotation, so that the front end of the screw 50 applies stable pressure to the second end 602 of the positioning pin 60, thereby preventing external forces from causing secondary damage to the positioning pin 60 or the water bird body 80.

[0064] like Figure 1 、 2 , 9 and 10, the screw rod 50 further includes a torsion bar 502, which is connected to the rear end of the screw rod 50. The torsion bar 502 and the rear end of the screw rod 50 are connected in a "T" shape, which facilitates the user to apply torque to the screw rod 50 and facilitates the user to perform disassembly operations. In the embodiment of the present application, in order to facilitate disassembly and storage, the torsion bar 502 can also be detachably connected to the rear end of the screw rod 50; for example, the torsion bar 502 and the rear end of the screw rod 50 are threadedly connected.

[0065] In order to better understand the technical solution of the present application, the operating principle of the water bird positioning pin disassembly device provided in the embodiment of the present application is explained below.

[0066] As shown in FIG8( a ), a positioning pin 60 is disposed in the water bird body 80 and is provided with a limiting groove 603. During the geophysical exploration operation of the marine streamer, the notch of the limiting groove 603 faces upward, the lower end of the limiting screw 70 is engaged in the limiting groove 603, and the upper end of the limiting screw 70 is engaged with the corresponding clamping ring on the streamer, thereby fixing the water bird body 80 in a specific position on the streamer, thereby preventing the water bird body 80 from slipping back and forth at the specific position on the streamer. At this time, the positioning pin 60 is in a non-detachable state.

[0067] As shown in Figure 8(b), when the positioning pin 60 is disassembled for maintenance needs, the positioning pin 60 is first rotated 180 degrees to disengage the front end of the limiting screw 70 from the limiting groove 603, that is, the front end of the limiting screw 70 slides to a position on the positioning pin 60 opposite to the limiting groove 603. At this time, the positioning pin 60 is in a detachable state, and the first end 601 of the positioning pin 60 can be pushed out of the water bird body 80 by the screw 50.

[0068] Then, if Figure 2 As shown, the support member 10 is sleeved on the water bird body 80, and the U-shaped accommodating space of the support member 10 is flush with the position of the water bird body 80 where the end of the positioning pin 60 is located in the horizontal direction; and as shown in Figure 9 (a), the groove 202 on the first base 20 is then sleeved on the first end 601 of the positioning pin 60, and the screw 50 is rotated so that the front end of the screw 50 abuts against the second end 602 of the positioning pin 60; and as shown in Figure 9 (b), the screw 50 is continuously rotated and pressure is continuously applied to the second end 602 so that the second end 602 is sunk into the water bird body 80; at this time, and as shown in Figure 9 (b), the screw 50 is continuously rotated and pressure is continuously applied to the second end 602 so that the second end 602 is sunk into the water bird body 80; Figure 10 As shown, the first end 601 is subjected to continuous lateral pressure and sinks into the groove 202, that is, the first end 601 is squeezed out of the shell of the water bird body 80; then, the screw 50 is rotated in the opposite direction to separate the front end of the screw 50 from the second end 602, and the positioning pin 60 is removed to complete the disassembly operation.

[0069] The water bird positioning pin disassembly device provided in the embodiment of the present application is light in weight, small in size, and easy to disassemble and store. It is very convenient to carry, and the disassembly operation is efficient and practical.

[0070] Compared with the previous disassembly method, a fixed bench vise is no longer used to disassemble the water bird locating pin, which can effectively avoid secondary damage to the water bird body. At the same time, the structural design of the disassembly device is simple, and the original multi-person disassembly operation can be converted into a single-person disassembly operation, which is conducive to saving manpower, and therefore has a dual effect in saving economy and time.

[0071] The water bird disassembly device provided in the embodiment of the present application is very suitable for on-site disassembly operations of marine seismic towline geophysical exploration operations, and is suitable for equipment maintenance operations on any marine seismic towline geophysical exploration ship, such as marine geophysical exploration two-dimensional seismic single-cable geophysical exploration ship, three-dimensional seismic multi-cable geophysical exploration ship and marine high-resolution seismic geophysical exploration ship, etc. As long as the ship uses water birds to control the sinking of the towline, the disassembly device provided in the embodiment of the present application can use.

[0072] The above description is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any variation, modification or equivalent substitution made by those skilled in the art without departing from the technical concept of the present application, and all embodiments obtained, shall fall within the scope of protection of the claims of the present application.
