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

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

[0075] like Figure 1 , Figure 2 As shown, the transponder body 100 includes a support tube 102, the bottom of the support tube 102 is threadedly connected to the sealing seat 103, and the top is inserted with an inner hole plug 104, the inner hole plug 104 is interference fit with the support tube 102, and the limiting groove 101 is set on the inner hole plug 104. A circuit board 105 is vertically arranged in the support tube 102, and a clamping ring 106 for clamping the circuit board 105 is movably arranged at the top of the support tube 102, and the inner hole plug 104 can clamp and fix the clamping ring 106. At the same time, two limiting notches 107 are arranged on the clamping ring 106, and the two sides of the top of the circuit board 105 can be respectively inserted into the corresponding limiting notches 107 to realize the positioning of the circuit board 105.

[0076] like Figure 3 to Figure 14 An embodiment of the present invention is shown, in which an auxiliary disassembly and assembly tool for a marine acoustic transponder is disclosed, comprising an outer casing disassembly and assembly part 1 and a transponder body disassembly and assembly part 2, wherein 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, Figure 3 , Figure 4 , Figure 5As shown, the outer casing disassembly and assembly part 1 includes a positioning seat 11 and a push column 12. The positioning seat 11 is used to be placed on the external platform, and the bottom of the acoustic transponder can be inserted into the positioning seat 11, and the acoustic transponder is kept vertical, so as to achieve the fixation of the acoustic transponder, so as to facilitate the staff to disassemble and assemble the limit screw 302 and the clamping card 300. The push column 12 can abut against the transponder body 100, and the push column 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, so as to achieve the disassembly and assembly of the outer casing 200.

[0078] In one embodiment, Figure 5 As shown, the bottom of the push column 12 is fixedly connected with an elastic shock-absorbing seat 13, which can be placed on the external platform and keep the push column 12 vertical. When the outer casing 200 is disassembled, the transponder body 100 can be aligned with the push column 12, and then the acoustic transponder can be controlled to move downward, so that the push column 12 hits the transponder body 100, thereby ejecting the transponder body 100. The shock-absorbing seat 13 can play a good role in buffering and energy absorption, preventing the push column 12 from rigidly colliding with the external platform, thereby reducing the risk of damage to the external platform or the push column 12.

[0079] In one embodiment, Figure 3 , Figure 4 As shown, the positioning seat 11 includes a vertically arranged positioning cylinder 111 and a limiting cylinder 112, the limiting cylinder 112 is coaxially arranged in the positioning cylinder 111, and the limiting cylinder 112 is fixedly connected to the positioning cylinder 111. At the same time, the top of the limiting cylinder 112 is integrally formed with a limiting inclined surface 113, when the top or bottom of the outer casing 200 is inserted into the positioning cylinder 111, the inclined surface of the top or bottom of the outer casing 200 can be closely abutted against the limiting inclined surface 113, thereby realizing stable support of the outer casing 200.

[0080] In one embodiment, Figure 5 As shown, the outer casing disassembly and assembly part 1 further includes a striking hammer 14 and a threaded column 15. The hammer head of the striking hammer 14 is used to strike the transponder body 100 to loosen the transponder body 100 and the outer casing 200. The threaded column 15 is fixed to the top of the hammer rod of the striking hammer 14, and the threaded column 15 can be threadedly matched with the limiting groove 101, so that the staff can pull the transponder body 100 out of the outer casing 200 by striking the hammer 14, or push the transponder body 100 into the outer casing 200.

[0081] Since the acoustic transponder is placed underwater for a long time, mud 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 pushing column 12, the hammer head of the striking hammer 14 can be used to knock the transponder body 100 to loosen the transponder body 100 and the outer casing 200, and then the transponder body 100 can be pushed out of the outer casing 200 by the pushing column 12, or the threaded column 15 is threadedly matched with the limiting groove 101, and the transponder body 100 is pulled out of the outer casing 200 by pulling the striking hammer 14.

[0082] In one embodiment, Figure 7 , Figure 8 As shown, the outer casing disassembly and assembly part 1 further includes a puller seat 16 and a multi-claw puller 17. The puller seat 16 is used to be sleeved on the outer casing 200 and to form a positioning match with one of the positioning ring grooves 203. The multi-claw puller 17 is used to cooperate 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 the hammer head of the hammer 14 is used to knock the transponder body, but the transponder body and the outer casing still cannot be loosened, the puller seat 16 can be sleeved on the lower end of the outer casing, and the puller seat 16 is positioned and matched with the positioning ring groove at the lower end. Subsequently, the multiple positioning hooks of the multi-claw puller 17 are respectively hooked and fixed to the puller seat 16, and the push rod of the multi-claw puller 17 is abutted against the transponder body. At this time, the push rod is driven to move by the hydraulic control unit of the multi-claw puller 17, and then the push rod can push the transponder body out of the outer casing.

[0084] In one embodiment, Fig. 9 , Fig.10 As shown, the puller seat 16 includes an annular receiving seat 161, and the receiving seat 161 can be sleeved on the outer casing 200. A plurality of puller grooves 162 are arranged on the top of the receiving seat 161. The plurality of puller grooves 162 are arranged at equal intervals along the circumference of the receiving seat 161, and a plurality of positioning hooks of the multi-claw puller 17 can be respectively inserted into the corresponding puller grooves 162. At the same time, a positioning inclined surface 163 is respectively provided at the bottom of each puller groove 162, and the positioning inclined surface 163 matches the positioning hook of the multi-claw puller 17, so as to realize the close hooking and matching between the multi-claw puller 17 and the receiving seat 161.

[0085] In this embodiment, six pulling 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, and the number of pulling grooves 162 can be set according to the number of positioning hooks of the multi-claw puller 17.

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

[0087] In one embodiment, Figure 1 , Figure 2 As shown, the thickness of the stopper 165 is the same as the width of the positioning ring groove 203, so that the stopper 165 can be tightly engaged with the positioning ring groove 203. At the same time, a guide slope 167 is provided at the upper end of each stopper 165, and the stopper 165 can move toward the outer edge position of the receiving seat 161 under the action of the guide slope 167 and the outer casing 200, so that the receiving seat 161 can be smoothly sleeved on the outer casing 200.

[0088] When the transponder body 100 needs to be disassembled, the receiving seat 161 is sleeved on the bottom of the outer casing 200, and the receiving seat 161 is pushed to move upward. When the limit block 165 is aligned with the positioning ring groove 203 at the lower end, the multiple control springs 166 respectively push the corresponding limit blocks 165 to move, and the multiple limit blocks 165 are respectively stuck in the positioning ring groove 203. Then, the multi-claw puller 17 can be installed to ensure that the positioning hook of the multi-claw puller 17 is stuck in the corresponding puller groove 162, and the positioning hook of the multi-claw puller 17 is tightly against the positioning inclined surface 163, and then the transponder body 100 can be ejected by the push rod of the multi-claw puller 17. Then, the multi-claw puller 17 is disassembled, and then the receiving seat 161 is pushed to continue to move upward until the receiving seat 161 is separated from the outer casing 200.

[0089] Similarly, when the transponder body 100 needs to be installed, the receiving seat 161 is placed on the top of the outer casing 200, and the receiving seat 161 is pushed to move downward. When the limit block 165 is aligned with the positioning ring groove 203 at the upper end, the multiple control springs 166 push the corresponding limit blocks 165 to move, and the multiple limit blocks 165 are respectively stuck 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, and the transponder body 100 is pushed into the outer casing 200 by the push rod of the multi-claw puller 17. Subsequently, the multi-claw puller 17 is disassembled, and then the receiving seat 161 is pushed to continue to move downward until the receiving seat 161 is separated from the outer casing 200.

At the same time, a plurality of supporting holes 164 are respectively arranged through the supporting ring 169, and the plurality of supporting holes 164 are respectively connected to the supporting ring cavity 171.
