Description

Technical Field

[0001] The invention relates to the technical field of underwater detection, and in particular to a sonar and an assembly method thereof. Background Art

[0002] Sonar technology plays a critical role in many fields such as ocean exploration, underwater navigation, fishing, and military anti-submarine warfare. Sonar can detect, locate, identify, and track targets by emitting sound wave signals and receiving reflected echoes.

[0003] Under the existing technical conditions, the sonar disclosed in the Chinese invention patent with publication number CN118226449A is not equipped with a capacitor module. The sonar transmitting array requires a large amount of electrical energy to drive when transmitting sound wave signals, and the sonar system of the prior art cannot gather enough energy in an instant to meet the needs of the transmitting array due to the lack of capacitor modules. This limits the intensity of the sound wave signal emitted by the transmitting array, thereby affecting the overall detection performance and range of the sonar. For example, in deep-sea detection, due to the strong absorption and scattering effect of water on sound waves, if the energy of the transmitted sound wave signal is insufficient, the echo signal will be very weak, making it difficult to effectively detect and identify the target; in military application scenarios, the weaker sound wave signal transmission capability may cause the enemy target to detect our detection behavior in advance, or fail to accurately lock the enemy target at a long distance, greatly reducing the combat effectiveness and strategic advantage.

[0070] With reference to the accompanying drawings of the present invention Figures 1 to 25A sonar according to a preferred embodiment of the present invention will be disclosed and explained in the following description, wherein the sonar includes an electronic cabin 10, a capacitor module 20, a circuit control module 30, a collection module 40 and a cabin cover 50.

[0071] Specifically, refer to the attached Figures 1 to 4 The electronic cabin 10 includes a cabin body 11, a transmitting array 12 and a receiving array 13, and the transmitting array 12 and the receiving array 13 are respectively arranged in the cabin body 11. It should be noted that the specific manner in which the transmitting array 12 and the receiving array 13 are arranged in the cabin body 11 is not limited in the sonar of the present invention. For example, the transmitting array 12 and the receiving array 13 can be arranged in the cabin body 11 through a vulcanization process, so that the cabin body 11, the transmitting array 12 and the receiving array 13 form a whole.

[0072] Reference Figure 2 , Figure 5 and Figure 7 The cabin 11 has a cabin cavity 111, the capacitor module 20, the circuit control module 30 and the acquisition module 40 are respectively installed in the cabin cavity 111 of the cabin 11, and the circuit control module 30 is respectively connected to the transmitting array 12, the capacitor module 20 and the acquisition module 40. The hatch 50 is watertightly installed on the cabin 11 to close the cavity of the cabin cavity 111 of the cabin 11.

[0073] Different from the prior art, the sonar of the present invention provides the capacitor module 20 for storing electrical energy. When the transmitting array 12 needs to transmit a sound wave signal, the capacitor module 20 can instantly release a large amount of electrical energy to drive the transducer of the transmitting array 12 to work, accurately meeting the working requirements of the transmitting array 12, thereby significantly improving the performance of the sonar in various application scenarios and providing more powerful technical support for the development and progress of ocean-related fields.

[0074] It is worth mentioning that the number of the capacitor modules 20 is not limited in the sonar of the present invention. Figures 1 to 25 In this specific example of the sonar of the present invention shown, the number of the capacitor modules 20 is three. It can be understood that in other optional examples of the sonar of the present invention, the number of the capacitor modules 20 can be one, two or more than four, that is, the number of the capacitor modules 20 can be selected as needed.

[0075] In addition, refer to the attached Figures 1 to 4 , Figure 7The sonar includes a watertight terminal 60, which is watertightly mounted on the hatch cover 50, the inner end of the watertight terminal 60 (i.e., the end of the watertight terminal 60 extending to the cabin cavity 111 of the cabin 11) is connected to the circuit control module 30, and the outer end of the watertight terminal 60 can be connected to a ship or a submersible. Specifically, the hatch cover 50 has a hatch cover through hole 51, and one end of the watertight terminal 60 extends to the cabin cavity 111 of the cabin 11 through the hatch cover through hole 51 of the hatch cover 50 to form the inner end of the watertight terminal 60, and accordingly, the end of the watertight terminal 60 exposed to the outside is the outer end of the watertight terminal 60. Preferably, a screw can be used to lock the watertight terminal 60 to the hatch cover 50. Optionally, in other optional examples of the sonar of the present invention, the watertight terminal 60 can be watertightly mounted on the cabin 11.

[0076] Reference Figure 3 , Figure 5 , Figure 7 and Fig. 9 The chamber 111 of the chamber body 11 has a first installation chamber 1111, a second installation chamber 1112 and a third installation chamber 1113, wherein the first installation chamber 1111 is located below the second installation chamber 1112 (based on the attached Figure 5 From the perspective shown), the first installation cavity 1111 can be half-surrounded by the transmitting array 12, the third installation cavity 1113 is located at the end of the second installation cavity 1112, the width dimension of the first installation cavity 1111 is smaller than the width dimension of the second installation cavity 1112 and smaller than the width dimension of the third installation cavity 1113, the capacitor module 20 is installed in the first installation cavity 1111 of the cabin 11, the circuit control module 30 is installed in the second installation cavity 1112 of the cabin 11, and the acquisition module 40 is installed in the third installation cavity 1113 of the cabin 11.

[0077] Since the capacitor module 20 is installed in the first installation cavity 1111 of the cabin 11, the capacitor module 20 can be half-wrapped by the transmitting array 12, so as to make full use of the space of the cabin cavity 111 of the cabin 11, avoid the capacitor module 20 occupying more space, and further facilitate the miniaturization and lightweight of the sonar. Since the second installation cavity 1112 of the cabin 11 is located above the first installation cavity 1111, and the circuit control module 30 is installed in the second installation cavity 1112 of the cabin 11, the cabin 11 and the circuit control module 30 can clamp the capacitor module 20, avoid the capacitor module 20 shaking or shifting in the first installation cavity 1111 of the cabin 11, and facilitate to ensure the reliability and stability of the sonar. That is to say, the capacitor module 20 is stably clamped between the cabin 11 and the circuit control module 30.

[0078] In addition, the positional relationship among the first installation cavity 1111, the second installation cavity 1112 and the third installation cavity 1113 of the cabin body 11 enables the capacitor module 20, the circuit control module 30 and the acquisition module 40 of the sonar to be reasonably arranged, which not only reduces the electromagnetic interference between each other, but also can reasonably utilize the space of the cabin cavity 111 of the cabin body 11, making the structure of the sonar more compact.

[0079] Reference Fig. 9 and Fig.12 The acquisition module 40 has a first terminal 41, and the receiving array 13 has a front amplifier board 131, the front amplifier board 131 includes a first soft board 1311 and a second terminal 1312 provided on the first soft board 1311, the first soft board 1311 of the front amplifier board 131 extends to the second installation cavity 1112 through the first installation cavity 1111 of the cabin body 11, and the second terminal 1312 of the front amplifier board 131 and the first terminal 41 of the acquisition module 40 are connected, so that the acquisition module 40 is connected to the receiving array 13.

[0080] In the attached Figures 1 to 25 In this specific example of the sonar of the present invention shown, the first terminal 41 of the acquisition module 40 and the second terminal 1312 of the receiving array 13 are pluggable structures. After the acquisition module 40 is installed in the third installation cavity 1113 of the cabin 11, the second terminal 1312 of the receiving array 13 is inserted into the first terminal 41 of the acquisition module 40, so that the acquisition module 40 and the receiving array 13 can be conductively connected.

[0081] Since the first terminal 41 of the acquisition module 40 and the second terminal 1312 of the receiving array 13 are plug-in structures, in order to prevent the second terminal 1312 of the receiving array 13 from falling off from the first terminal 41 of the acquisition module 40, the sonar of the present invention further includes a pressure plate 70, which is installed on the acquisition module 40, and the pressure plate 70 is used to apply pressure to the second terminal 1312 of the receiving array 13 and the first terminal 41 of the acquisition module 40.

[0082] It can be understood that the installation step of the pressing plate 70 is performed after the installation step of the acquisition module 40 and the connection step of the first wiring terminal 41 of the acquisition module 40 and the second wiring terminal 1312 of the receiving array 13. Therefore, the installation process of the pressing plate 70 is performed in the cabin cavity 111 of the cabin body 11. In order to facilitate the installation of the pressing plate 70 in a small space, the pressing plate 70 is installed in the attached Figures 1 to 25 In this specific example of the sonar of the present invention shown, the acquisition module 40 has a stud 42, and the stud 42 protrudes toward the first installation cavity 1111 or the second installation cavity 1112 of the cabin 11, and the pressure plate 70 has at least one pressure plate through-hole 71. The sonar further includes at least one nut 80, and the pressure plate 70 is arranged on the outer side of the second terminal 1312 of the receiving array 13 in such a way that the free end of the stud 42 of the acquisition module 40 passes through the pressure plate through-hole 71, and the nut 80 is screwed on the free end of the stud 42. During the process of screwing the nut 80 onto the free end of the stud 42, the nut 80 and the stud 42 cooperate with each other so that the pressure plate 70 moves toward the second terminal 1312 of the receiving array 13 to press the second terminal 1312 of the receiving array 13 toward the first terminal 41 of the acquisition module 40. In this way, the pressure plate 70 is installed on the acquisition module 40, and the pressure plate 70 is used to apply pressure to the second terminal 1312 of the receiving array 13 and the first terminal 41 of the acquisition module 40 to prevent the second terminal 1312 of the receiving array 13 from falling off from the first terminal 41 of the acquisition module 40.

[0083] It can be understood that after the pressure plate 70 is installed on the acquisition module 40, the pressure plate 70 can isolate the acquisition module 40 from the capacitor module 20 and isolate the acquisition module 40 from the circuit control module 30. In this way, the pressure plate 70 can effectively shield the electromagnetic interference to the acquisition module 40, thereby helping to improve the acquisition accuracy of the acquisition module 40, which is crucial to improving the overall performance of the sonar.

[0084] In other words, the pressure plate 70 can not only press the second terminal 1312 of the receiving array 13 toward the first terminal 41 of the acquisition module 40 to prevent the second terminal 1312 of the receiving array 13 from falling off from the first terminal 41 of the acquisition module 40, but also shield electromagnetic interference to the acquisition module 40, thereby improving the overall performance of the sonar.

[0085] Preferably, in the attached Figures 1 to 25 In this specific example of the sonar of the present invention shown, the number of the studs 42 of the acquisition module 40 is four, the number of the pressure plate through holes 71 of the pressure plate 70 is four, and accordingly, the number of the nuts 80 is four. The free ends of the four studs 42 of the acquisition module 40 respectively pass through the four pressure plate through holes 71 of the pressure plate 70 and then are screwed with four nuts 80. In this way, the pressure plate 70 can apply uniform pressure to the second terminal 1312 of the receiving array 13 and the first terminal 41 of the acquisition module 40.

[0086] Reference Figure 7 and Fig. 9 The cabin 11 has an isolation plate 112, and the isolation plate 112 is located at the connecting position of the first installation cavity 1111 and the third installation cavity 1113 of the cabin 11. The first soft board 1311 of the front plate 131 of the receiving array 13 is located in the first installation cavity 1111 of the cabin 11, so that when the acquisition module 40 is installed in the third installation cavity 1113 of the cabin 11, the isolation plate 112 can isolate the acquisition module 40 and the first soft board 1311 to prevent the first soft board 1311 from being scratched, thereby protecting the first soft board 1311.

[0087] Reference Figure 3 , Figure 4 and Figure 7The sonar includes a socket module 90, and the socket module 90 includes a socket bracket 91 and a socket body 92 disposed on the socket bracket 91. After the socket module 90 sinks into the first installation cavity 1111 of the cabin 11, the socket bracket 91 is installed on the cabin 11. For example, a screw can be used to install the socket bracket 91 on the cabin 11. In this way, the socket module 90 can be reliably installed in the first installation cavity 1111 of the cabin 11. The capacitor module 20 and the transmitting array 12 are respectively connected to the socket body 92. For example, the capacitor module 20 and the transmitting array 12 can be respectively connected to the socket body 92 by a flying wire process. Preferably, the socket module 90 is located between two adjacent capacitor modules 20 to save space.

[0088] Reference Fig.16 The circuit control module 30 has a socket 31. When the circuit control module 30 is installed in the second installation cavity 1112 of the cabin 11, the socket body 92 is inserted into the socket 31 of the circuit control module 30, so that the circuit control module 30 is connected to the capacitor module 20 and the transmitting array 12. It can be understood that the screw can be used to install the circuit control module 30 in the cabin 11 to ensure the reliability of the plug-in relationship between the socket 31 of the circuit control module 30 and the socket body 92.

The plurality of spacers 38 are used to lock the third control board 363 on the first control board 361. The third control board 363 is conductively connected to the first control board 361. The spacers 38 are used to suspend the third control board 363 above the second control board 362 so that there is a gap between the second control board 362 and the third control board 363. In this way, it is beneficial for the circuit control module 30 to dissipate heat and reduce the temperature of the first control board 361, the second control board 362 and the third control board 363 when working for a long time. The cover plate 37 can be fixedly mounted on the spacer 38 by a screw to set the cover plate 37 above the top control circuit board 36.

[0103] Preferably, the acquisition module 40 includes at least one support tube 48, one end of the support tube 48 abuts against the top of the cover side plate 47, and the other end abuts against the second soft board 39, and the screw is screwed to the top of the cover side plate 47 after passing through the through hole of the second soft board 39 and the support tube 48 to ensure the reliability of the conductive relationship between the third terminal 391 of the second soft board 39 and the fourth terminal 43 of the acquisition module 40.

[0104] In the attached Figures 1 to 25 In this specific example of the sonar of the present invention shown, the bottom side plate 46 and the cover side plate 47 are made of a material with good thermal conductivity, such as aluminum, copper, aluminum alloy, copper alloy, etc., so that the heat generated by the collection board 44 when the collection module 40 is working can be quickly dissipated through the bottom side plate 46 and the cover side plate 47.

[0105] The connecting end of the stud 42 is connected to the cover side plate 47, for example, Figures 1 to 25 In the specific example of the sonar of the present invention shown, the cover side plate 47 may have at least one screw hole 473, and the connecting end of the stud 42 is screwed to the cover side plate 47 in a manner of extending into the screw hole 473 of the cover side plate 47. Alternatively, in other examples of the sonar of the present invention, the connecting end of the stud 42 may also be welded to the cover side plate 47.

[0106] In addition, refer to the attached Fig.12 and Fig.14 The cover side plate 47 has at least one side plate boss 474, and the side plate boss 474 surrounds the connection end of the stud 42, and the side plate boss 474 is slightly higher than the first terminal 41. In this way, after the second terminal 1312 of the receiving array 13 is inserted into the first terminal 41 of the acquisition module 40 and the free end of the stud 42 is allowed to pass through the pressure plate through hole 71 of the pressure plate 70, the side plate boss 474 of the cover side plate 47 can support the pressure plate 70 to prevent the pressure plate 70 from applying excessive pressure to the second terminal 1312 of the receiving array 13 and the first terminal 41 of the acquisition module 40, thereby protecting the second terminal 1312 of the receiving array 13 and the first terminal 41 of the acquisition module 40.

[0107] Reference Figure 5 , Figure 6 , Fig. 9 , Fig.10 , Fig.12 and Fig.14The inner wall of the cabin 11 for defining the third installation cavity 1113 is provided with at least one extrusion platform 113, the extrusion platform 113 protrudes toward the third installation cavity 1113 and has an extrusion slope 1131, the cover side plate 47 has at least one guide groove 475 and at least one pressure slope 476, the pressure slope 476 is the groove bottom of the guide groove 475, when installing the collection module 40 in the third installation cavity 1113 of the cabin 11, first, the extrusion platform 113 of the cabin 11 is allowed to enter the guide groove 475 of the cover side plate 47, at this time, the extrusion slope 1131 of the extrusion platform 113 and the cover The pressure inclined surface 476 of the side panel 47 is in close contact with the inner wall of the cabin 11. Secondly, in the process of installing the collection module 40 on the cabin body 11 by means of a screw, the screw pushes the collection module 40 downward. At this time, the extrusion inclined surface 1131 of the extrusion platform 113 and the pressure inclined surface 476 of the cover side panel 47 cooperate with each other, so that the collection module 40 moves laterally during the downward movement and allows the bottom side panel 46 to fit tightly against the inner wall of the cabin body 11, thereby not only being able to reliably install the collection module 40 in the third installation cavity 1113 of the cabin body 11, but also being conducive to the rapid conduction of heat from the bottom side panel 46 to the cabin body 11.

[0108] Preferably, the cabin body 11 has two extrusion platforms 113, and the two extrusion platforms 113 are respectively located at the opposite ends of the third installation cavity 1113 of the cabin body 11. Correspondingly, the opposite ends of the cover side plate 47 respectively have a guide groove 475 and a pressure slope 476. In this way, after the collection module 40 is installed in the third installation cavity 1113 of the cabin body 11, it can be ensured that the opposite ends of the collection module 40 are evenly stressed, thereby preventing the collection module 40 from tilting.

[0109] Attached Figures 19 to 25 The assembly process of the sonar is shown, which is as follows.

[0110] Reference Fig.19 and Fig. 20 After connecting the capacitor module 20 and the socket body 92 of the socket module 90 and connecting the transmitting array 12 and the socket body 92 by the flying wire process, the capacitor module 20 and the socket module 90 are placed in the first installation cavity 1111 of the cabin 11, and the bottom of the socket bracket 91 is screwed to the cabin 11. It can be understood that glue can be applied between the peripheral wall of the capacitor module 20 and the inner wall of the cabin 11, and the peripheral wall of the capacitor module 20 and the inner wall of the cabin 11 are bonded by the glue to prevent the capacitor module 20 from moving relative to the cabin 11.

[0111] Reference Fig.21 First, after the bottom of the collection module 40 is inserted into the third installation cavity 1113 of the cabin 11, the extrusion platform 113 of the cabin 11 is allowed to enter the guide groove 475 of the collection module 40. At this time, the pressure inclined surface 476 of the collection module 40 and the extrusion inclined surface 1131 of the extrusion platform 113 correspond to each other in the horizontal direction and fit each other. Secondly, in the process of locking the collection module 40 in the cabin 11 by the screw, the screw pushes the collection module 40 down. The collecting module 40 is moved downward, and the pressing inclined surface 1131 of the pressing platform 113 and the pressing inclined surface 476 of the cover side plate 47 cooperate with each other, so that the collecting module 40 moves laterally during the downward movement and allows the bottom side plate 46 to fit closely to the inner wall of the cabin 11. Then, the second wiring terminal 1312 of the front plate 131 of the receiving array 13 is inserted into the first wiring terminal 41 of the collecting module 40 to connect the collecting module 40 and the receiving array 13 in a conductive manner. It can be understood that since the isolation plate 112 of the cabin 11 isolates the first soft board 1311 of the front plate 131 and the third installation cavity 1113 of the cabin 11, the collecting module 40 can be prevented from scratching the first soft board 1311 during the insertion of the bottom of the collecting module 40 into the third installation cavity 1113 of the cabin 11, so as to protect the first soft board 1311.

[0112] Reference Fig. 22 , allowing the free ends of the studs 42 of the acquisition module 40 to pass through the pressing plate through holes 71 of the pressing plate 70 respectively, and the pressing plate 70 covers the second wiring terminals 1312 of the front placing plate 131 .

[0113] Reference Fig.23, respectively screw the nuts 80 onto the free ends of the studs 42 of the collection module 40 . It can be understood that, in the sonar of the present invention, since the capacitor module 20 and the socket module 90 are first installed in the first installation cavity 1111 of the cabin 11, and then the pressure plate 70 is installed, the operation of installing the pressure plate 70 needs to be performed in a narrow space. In order to firmly install the pressure plate 70 on the acquisition module 40, in the sonar of the present invention, a scheme is adopted in which the stud 42 is preset in the acquisition module 40, and the nut 80 is screwed on after the free end of the stud 42 passes through the pressure plate through hole 71 of the pressure plate 70. In this way, when a tool (for example, a wrench) is used to rotate the nut 80, the tool rotates the nut 80 in the circumferential direction of the nut 80 instead of rotating the nut 80 in the axial direction. Therefore, even in a narrow space, the pressure plate 70 can be firmly installed on the acquisition module 40 with the help of the stud 42 and the nut 80, and the capacitor module 20 can be avoided from being affected.

[0114] Reference Fig.24 , install the circuit control module 30 in the second installation cavity 1112 of the cabin 11. During the installation process, the guide columns 911 of the socket bracket 91 are respectively inserted into the guide holes 32 of the circuit control module 30 to guide the top of the socket body 92 to insert into the socket 31 of the circuit control module 30, thereby ensuring that the socket body 92 and the socket 31 of the circuit control module 30 are conductive. After installation, the guide columns 911 of the socket bracket 91 and the guide holes 32 of the circuit control module 30 cooperate with each other to avoid lateral force on the socket body 92 and the socket 31 of the circuit control module 30, thereby ensuring the reliability of the conductive relationship between the socket body 92 and the socket 31 of the circuit control module 30. Subsequently, the third terminal 391 of the second flexible board 39 is inserted into the fourth terminal 43 of the acquisition module 40, and the second flexible board 39 is installed on the acquisition module 40 using a screw, so that the acquisition module 40 and the circuit control module 30 are conductively connected.

[0115] Reference Fig.25 After the circuit control module 30 is conductively connected to the watertight terminal 60 , the hatch cover 50 is watertightly installed on the cabin body 11 to close the opening of the cabin cavity 111 of the cabin body 11 .
