[0045] The circuit board 20 is accommodated in the housing space 111 of the housing 10. For example, in one specific example of the Doppler underwater measuring device of the present application, after the circuit board 20 is placed in the housing space 111 through the bottom opening of the housing space 111 of the housing main body 11, screws are used to screw the circuit board 20 to the housing main body 11, so that the circuit board 20 is stably accommodated in the housing space 111 of the housing main body 11.

[0046] Each of the Doppler transducers 40 is mounted in each of the mounting grooves 112 of the housing main body 11, and the lead wire 41 of the Doppler transducer 40 extends to the housing space 111 of the housing main body 11 through the communication passage 113 of the housing main body 11 and is connected to the circuit board 20. After the Doppler transducer 40 is mounted in the mounting groove 112 of the housing main body 11, the gap between the housing main body 11 and the Doppler transducer 40 can be filled with glue, so that the Doppler transducer 40 is reliably mounted in the mounting groove 112 of the housing main body 11, and the water tightness of the mounting position of the Doppler transducer 40 and the housing main body 11 is ensured by the glue.

[0047] The housing 10 further comprises a bottom cover 12, which is mounted to the shell body 11 and which closes a bottom opening of the housing space 111 of the shell body 11, so that the circuit board 20 is hidden between the shell body 11 and the bottom cover 12, making the circuit board 20 visually invisible, to protect the circuit board 20. In particular, the shell body 11 has at least one threaded hole 114, the bottom cover 12 has at least one screw hole 121, after the bottom cover 12 is covered on the shell body 11, the screw hole 121 of the bottom cover 12 and the threaded hole 114 of the shell body 11 correspond, wherein the Doppler underwater measuring device further comprises at least one screw 50, the threaded end of the screw 50 extends to the threaded hole 114 of the shell body 11 after passing through the screw hole 121 of the bottom cover 12, and the screw 50 is screwed to the shell body 11, so that the bottom cover 12 is mounted to the shell body 11 by the screw 50. Preferably, the number of threaded holes 114 of the shell body 11 is two, the number of screw holes 121 of the bottom cover 12 is two, and accordingly, the number of screws 50 is two,

[0048] The wiring terminal 30 is arranged on the bottom cover 12, and the wiring terminal 30 is connected to the circuit board 20. Compared with the prior art, in the Doppler underwater transducer of the present application, since the wiring terminal 30 is arranged on the bottom cover 12, the peripheral wall of the shell body 11 can form a complete and continuous surface, so that, after the bottom of the Doppler underwater measuring device is embedded into the embedding groove 101 of the ship or vehicle 100, the water tightness of the peripheral wall of the shell body 11 of the shell 10 of the Doppler underwater measuring device and the mounting position of the ship or vehicle 100 can be ensured, the mounting position of the shell body 11 and the bottom cover 12 is prevented from being contacted by water, that is, water is prevented from reaching the mounting position of the shell body 11 and the bottom cover 12 after passing through the peripheral wall of the shell body 11 and the inner wall of the ship or vehicle 100 for forming the embedding groove 101, so that water cannot enter the shell space 111 of the shell body 11 through the mounting position of the shell body 11 and the bottom cover 12, and thus the shell space 111 of the shell body 11 does not need to be filled with glue, in this way, first, since the shell space 111 of the shell body 11 does not need to be filled with glue, the raw material cost can be saved, second, since the shell space 111 of the shell body 11 does not need to be filled with glue, the glue filling step can be omitted during the assembly of the Doppler underwater measuring device, so as to reduce the production cost of the Doppler underwater measuring device and improve the production efficiency, third, since the shell space 111 of the shell body 11 does not need to be filled with glue, the Doppler underwater measuring device is convenient to repair when it is damaged, and fourth, after the bottom of the Doppler underwater measuring device is embedded into the embedding groove 101 of the ship or vehicle 100, since water can be prevented from reaching the mounting position of the shell body 11 and the bottom cover 12 after passing through the peripheral wall of the shell body 11 and the inner wall of the ship or vehicle 100 for forming the embedding groove 101, the waterproof performance requirement of the mounting position of the shell body 11 and the bottom cover 12 can be reduced, so as to reduce the waterproof technical difficulty of the Doppler underwater measuring device.

[0049] Preferably, in the attached Figures 1 to 10 In this specific example of the Doppler underwater measuring device of the present application shown in the drawings, the number of the Doppler transducers 40 is four, accordingly, the shell body 11 has four mounting slots 112 and four communication passages 113, four Doppler transducers 40 are respectively arranged in the four mounting slots 112 of the shell body 11, and the wires 41 of the four Doppler transducers 40 respectively extend to the shell space 111 of the shell body 11 through the four communication passages 113 and are respectively connected to the circuit board 20.

[0050] In addition, reference is made to the attachedFigure 4 and Figure 5 The bottom cover 12 has a support platform 120 protruding into the housing space 111 of the shell body 11 for supporting the circuit board 20.

[0051] Further, referring to the attached drawings, Figure 6 , Figure 8 and Figure 9 The bottom cover 12 has a terminal through hole 122, one end of the wiring terminal 30 extends to the outside of the housing 10 after passing through the terminal through hole 122 of the bottom cover 12, so as to set the wiring terminal 30 on the bottom cover 12. That is, one end of the wiring terminal 30 is located in the housing space 111 of the shell body 11, and the other end is located outside the housing 10, so that not only is it convenient to connect the inner end of the wiring terminal 30 (i.e. the end of the wiring terminal 30 located in the housing space 111 of the shell body 11) and the circuit board 20, but also it is convenient to plug the cable terminal of the cable of the ship or vehicle 100 into the outer end of the wiring terminal 30 (i.e. the end of the wiring terminal 30 located outside the housing 10).

[0052] Continuing to refer to the attached drawings, Figure 6 , Figure 8 and Figure 9 The Doppler underwater measuring device further comprises two screw columns 60, two of the screw columns 60 are respectively arranged on the bottom cover 12, and the two screw columns 60 are located on opposite sides of the wiring terminal 30, so that after the cable terminal of the cable of the ship or vehicle 100 is plugged into the outer end of the wiring terminal 30, the cable terminal of the cable of the ship or vehicle 100 can be locked on the two screw columns 60 using screws, so as to ensure that the cable terminal of the cable of the ship or vehicle 100 is reliably plugged into the wiring terminal 30.

[0053] In the specific example of the Doppler underwater measuring device of the present application shown in the attached drawings, the screw column 60 locks the wiring terminal 30 and the bottom cover 12, so that the wiring terminal 30 is reliably mounted on the bottom cover 12. Figures 1 to 10 Specifically, referring to the attached drawings,

[0054] , Figure 6 and Figure 8 and Figure 9The opposite sides of the terminal 30 are provided with a first through hole 31, the bottom cover 12 is provided with a second through hole 123, the second through hole 123 is located at the opposite side of the terminal through hole 122, the first through hole 31 of the terminal 30 and the second through hole 123 of the bottom cover 12 are corresponding, the screwing post 60 includes a post 61 and a nut 62, the post 61 includes an assembling section 611 and a threaded section 612 extending from the assembling section 611, the outer diameter of the assembling section 611 is larger than the inner diameter of the second through hole 123 of the bottom cover 12, the threaded section 612 of the post 61 screws the nut 62 after passing through the second through hole 123 of the bottom cover 12 and the first through hole 31 of the terminal 30, so that the screwing post 60 locks the terminal 30 and the bottom cover 12. At the same time, the screwing post 60 can be stably arranged on the bottom cover 12.

[0055] Reference is made to the accompanying drawings Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 The Doppler underwater measuring device includes at least one sealing ring 70, which is sleeved on the peripheral wall of the shell body 11. When the bottom of the Doppler underwater measuring device is embedded in the embedding groove 101 of the ship or vehicle 100, the peripheral wall of the shell body 11 and the inner wall of the ship or vehicle 100 for forming the embedding groove 101 extrude the sealing ring 70 to deform, so that the water tightness of the peripheral wall of the shell body 11 and the assembly position of the ship or vehicle 100 is ensured by the sealing ring 70. In this way, after the Doppler underwater measuring device enters the water, water is prevented from reaching the installation position of the shell body 11 and the bottom cover 12 through the peripheral wall of the shell body 11 and the inner wall of the ship or vehicle 100 for forming the embedding groove 101.

[0056] Further, the peripheral wall of the shell body 11 is provided with at least one annular groove 115, the depth of the annular groove 115 is smaller than the diameter of the sealing ring 70, the inner side of the sealing ring 70 is embedded in the annular groove 115 of the shell body 11, and the outer side of the sealing ring 70 protrudes from the peripheral wall of the shell body 11. In this way, when the bottom of the Doppler underwater measuring device is embedded in the embedding groove 101 of the ship or vehicle 100, the friction generated between the sealing ring 70 and the inner wall of the ship or vehicle 100 for forming the embedding groove 101 cannot cause the sealing ring 70 to slide or roll, so that the relative position of the sealing ring 70 and the shell body 11 cannot be changed, thereby ensuring the water tightness of the peripheral wall of the shell body 11 and the assembly position of the ship or vehicle 100.

[0057] Preferably, the peripheral wall of the shell body 11 has two mutually spaced ring grooves 115, and correspondingly, the number of the sealing rings 70 is two.

[0058] In the attached drawings: Figures 1 to 10 In this specific example of the Doppler underwater measuring device of the present application, the shell body 11 is made of aluminum alloy and is anodized, which makes the shell body 11 non-conductive. Therefore, in order to ground the circuit board 20, the Doppler underwater measuring device further comprises a grounding part 80, which is arranged on the shell body 11. The grounding line 81 of the grounding part 80 is connected to the circuit board 20, and the grounding part 80 has an exposed surface 82. After the Doppler underwater measuring device is put into water, the exposed surface 82 of the grounding part 80 is in contact with water, so as to achieve the grounding of the circuit board 20.

[0059] In the attached drawings: Figure 4 And Figure 5 The shell body 11 has a shell hole 116, which communicates the shell space 111 with the external environment. The grounding part 80 is water-tightly mounted in the shell hole 116 of the shell body 11, so as to arrange the grounding part 80 on the shell body 11. That is, in this specific example of the Doppler underwater measuring device of the present application, the grounding part 80 is embedded in the shell body 11, so as to avoid the grounding part 80 protruding from the surface of the shell body 11. In order to increase the sealing of the assembly position of the shell body 11 and the grounding part 80, the sealing ring 70 is arranged between the inner wall of the shell body 11 for forming the shell hole 116 and the grounding part 80.

[0060] It should be understood by those skilled in the art that the above description and the embodiments of the present application shown in the drawings are only examples and do not limit the present application.
