[0017] like Figure 1 and Figure 2 As shown, this embodiment provides a positioning tool for transducer installation, which overcomes the friction resistance between the transducer 2 and the electronic cabin 1 provided on one side during installation, and includes a universal pull rod 3 and a semicircular flange 4. The semicircular flange 4 is provided with two and has a semicircular structural feature, as shown in FIG. Figure 4 、 Figure 5 As shown, a complementary slot is provided at one end of the semicircular flange 4 for assembly and docking, and an open slot is provided on the side of the semicircular flange 4. The two semicircular flanges 4 are docked and assembled along the positioning circular grooves on the side of the electronic cabin 1 and fastened with bolts.

[0018] like Figure 6 Said universal rod 3 comprises a short screw 7, a long screw 8, a pull ring I 9, and a pull ring II 10; one end of the long screw 8 passes through the opening slot of the semicircular flange 4, and a gasket 5 and a nut 6 are provided between the long screw 8 and the semicircular flange 4, as shown in FIG. Figure 3 As shown; the other end of the long screw 8 is provided with a pull ring II 10, and the long screw 8 and the pull ring II 10 are assembled through a threaded structure, and have circumferential axial rotation freedom.

[0019] The pull ring II 10 is connected to the short screw 7 through the base at one end of the pull ring I 9, wherein the pull ring I 9 and the short screw 7 are assembled through a threaded structure and also have circumferential axial rotation freedom, and a universal joint structure is formed between the pull ring I 9 and the pull ring II 10.

[0020] The short screw 7 has a threaded feature at its other end, which is screwed into a screw hole on the side wall of the transducer 2 and tightened. Finally, during the assembly process, after the transducer 2 is docked with the electronics compartment 1, the nuts 6 are tightened evenly in sequence, using the screw force to pull the transducer 2 into the electronics compartment 1. Once the installation is successful, all the positioning tools can be removed.

[0021] The positioning tooling described in this embodiment is used to radially seal the transducer and the electronic compartment of the underwater equipment structure through multiple sealing rings. This special structure solves the problem that it is difficult to use general tooling in the positioning assembly.
