Description

Technical Field

[0001] This utility model relates to the field of underwater detection technology, and in particular to a side-scan sonar. Background Technology

[0002] Side-scan sonar, as a core device in the field of underwater detection, has become a key technical support for scenarios such as marine geological surveys, underwater target search and rescue, waterway safety inspection, and subsea pipeline maintenance, thanks to its high-resolution acoustic imaging capabilities. In existing side-scan sonar technologies, the transducer assembly, which is the core of acoustic signal transmission and reception, and the cabin are independent of each other. The transducer assembly is fixed to the outside of platforms such as submersibles and ships via brackets or towed bodies. The main control assembly, transmitting assembly, and acquisition assembly are also often installed as independent modules in other parts of the submersible, ship, or other platform. Power and signal transmission between the various components are achieved through watertight cables. The shortcomings of existing side-scan sonar technologies are as follows: First, because the transducer assembly, main control assembly, transmitting assembly, and acquisition assembly of existing side-scan sonar technologies are deployed independently, the integration of existing side-scan sonar technologies is low, and the deployment and maintenance costs are high. Moreover, the interfaces between the watertight cable and these components are easily affected by water flow impact, vibration, and seawater corrosion. Second, because the transducer assembly, main control assembly, transmitting assembly, and acquisition assembly of existing side-scan sonar technologies are connected through watertight cables, the signal is easily interfered with during transmission in each component, resulting in a decrease in detection accuracy and making it difficult to meet the requirements of high-precision detection.

[0034] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 14A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the side-scan sonar includes a housing 10, a transducer assembly 20, a watertight connector 30, a main control assembly 40, a transmitting assembly 50, at least one acquisition assembly 60, and a plurality of canopies 70, wherein the transducer assembly 20, the watertight connector 30, the main control assembly 40, the transmitting assembly 50, the acquisition assembly 60, and the canopies 70 are respectively disposed on the housing 10, and the transducer assembly 20, the watertight connector 30, the transmitting assembly 50, and the acquisition assembly 60 are respectively connected to the main control assembly 40, and the main control assembly 40, the transmitting assembly 50, and the acquisition assembly 60 are maintained in a sealed environment formed by the housing 10 and the canopies 70, thereby integrating the side-scan sonar of the present invention.

[0035] Specifically, the cabin 10 has multiple cavities 11 arranged along the length of the cabin 10, and adjacent cavities 11 are interconnected. In the side-scan sonar of this invention, the side where the opening of the cavity 11 of the cabin 10 is located is defined as the front, and the side of the cabin 10 opposite to the opening of the cavity 11 is defined as the back. The transducer assembly 20 is disposed on the back of the cabin 10. The watertight connector 30 is watertightly installed on the side of the cabin 10. The main control assembly 40, the transmitting assembly 50, and the acquisition assembly 60 are respectively installed in the cavities 11 at different positions of the cabin 10. The cover 70 is used to close the opening of the cavity 11 of the cabin 10, thus keeping the main control assembly 40, the transmitting assembly 50, and the acquisition assembly 60 in a sealed environment. In the side-scan sonar of this invention, the transducer assembly 20, the main control assembly 40, the transmitting assembly 50, and the acquisition assembly 60 are all installed in the cabin 10. In this way, on the one hand, watertight cables are not required between the components, which helps to improve the reliability and stability of the connection between the components. On the other hand, signal transmission between the components can be realized inside the cabin 10, which helps to improve the anti-interference capability of the side-scan sonar. Furthermore, it is conducive to the rapid and flexible deployment of the side-scan sonar.

[0036] Preferably, the back of the housing 10 has a mounting groove 12 and a plurality of wiring holes 13 connecting the mounting groove 12 and each of the housing cavities 11. The shape and size of the mounting groove 12 are consistent with the shape and size of the transducer assembly 20. The transducer assembly 20 is embedded in the mounting groove 12 of the housing 10 to prevent the transducer assembly 20 from protruding from the back of the housing 10. The cable of the transducer assembly 20 extends through the wiring holes 13 of the housing 10 to the housing cavities 11 and is subsequently connected to the acquisition assembly 60.

[0037] Preferably, the hull 10 has a mounting hole 14 communicating with one of the hull 10's cavities 11, and the watertight connector 30 is watertightly mounted to the mounting hole 14 of the hull 10. For example, in the attached... Figures 1 to 14 In this specific example of the side-scan sonar of the present invention shown, the mounting hole 14 of the housing 10 is connected to the cavity 11 of the housing 10 used for mounting the main control component 40, thereby facilitating the connection of the watertight connector 30 and the main control component 40.

[0038] Preferably, the cabin 10 has multiple connecting channels 15 that connect two adjacent cabin cavities 11. This facilitates wiring inside the cabin 10 to connect the transmitting component 50 and the acquisition component 60 to the main control component 40.

[0039] In the appendix Figures 1 to 14 In this specific example of the side-scan sonar of the present invention, the number of acquisition components 60 is multiple, for example, five acquisition components 60, and the number of cavities 11 of the cabin 10 is seven. The seven cavities 11 are arranged along the length of the cabin 10. The main control component 40 is installed in the fourth cavity 11 of the cabin 10. The first, second, third, fifth, and sixth cavities 11 of the cabin 10 are each equipped with one acquisition component 60, and the seventh cavity 11 of the cabin 10 is equipped with the transmission component 50. In this way, the structural arrangement of the various parts of the side-scan sonar is more reasonable and the structure is more compact.

[0040] It is worth mentioning that the specific manner in which the canopy 70 is installed on the cabin 10 is not limited in the side-scan sonar of this utility model. For example, in the attached... Figures 1 to 14 In this specific example of the side-scan sonar of the present invention shown, a set of screws 1000 can be used to install the hatch 70 onto the cabin 10.

[0041] In the appendix Figures 1 to 14In this specific example of the side-scan sonar of the present invention shown, the materials of the cabin 10 and the hatch 70 can be aluminum or aluminum alloy. The cabin 10 and the hatch 70 can be manufactured by milling and drilling processes. In this way, not only can the structural strength of the side-scan sonar be guaranteed, enabling the side-scan sonar to be used at deeper water depths, but the heat dissipation capacity of the side-scan sonar can also be improved.

[0042] To further improve the heat dissipation capability of the side-scan sonar and ensure its reliability during use, please refer to the appendix. Figure 3 , Figure 4 , Figures 6 to 10 The main control component 40 includes at least one heat-spreading mounting plate 41, at least one main control board 42, and a power module 43 connected to the main control board 42. The main control board 42 and the power module 43 are respectively mounted on the heat-spreading mounting plate 41. The heat-spreading mounting plate 41 is stacked and mounted on the bottom wall of the cavity 11 of the cabin 10 to house the main control component 40 in the cavity 11 of the cabin 10. For example, in the attached... Figures 1 to 14 In this specific example of the side-scan sonar of the present invention, a set of screws 1000 can be used to lock the heat-spreading mounting plate 41 to the bottom wall of the cavity 11 of the housing 10. It is understood that the main control board 42 is fitted with various types of electronic components such as chips, resistors, and capacitors. During operation, the main control board 42 will generate considerable heat. This heat is conducted to the housing 10 via the heat-spreading mounting plate 41 for dissipation, thereby improving the heat dissipation capacity of the side-scan sonar. Preferably, the heat-spreading mounting plate 41 is made of aluminum or aluminum alloy to improve its structural strength and heat dissipation capacity.

[0043] In the appendix Figures 1 to 14 In this specific example of the side-scan sonar of the present invention, the number of the heat-spreading mounting plates 41 can be two, and the two heat-spreading mounting plates 41 are arranged at intervals, that is, there is a gap between the two heat-spreading mounting plates 41 to avoid heat conduction between the two heat-spreading mounting plates 41. It can be understood that the two heat-spreading mounting plates 41 correspond to different positions of the main control board 42, and by preventing heat conduction between the two heat-spreading mounting plates 41, heat from one part of the main control board 42 can be effectively prevented from being conducted to other parts through these heat-spreading mounting plates 41.

[0044] Furthermore, the heat-spreading mounting plate 41 has multiple bosses 411, and the main control board 42 is locked to the bosses 411. Thus, a clearance cavity 401 can be formed between the heat-spreading mounting plate 41 and the main control board 42 to avoid contact with the electronic components of the main control board 42. In other words, by locking the main control board 42 to the bosses 411, contact between the electronic components of the main control board 42 and the heat-spreading mounting plate 41 can be avoided. This prevents stress on the electronic components of the main control board 42 during the assembly of the side-scan sonar, ensuring the reliability and stability of the main control board 42. Simultaneously, during operation, heat conducted through the heat-spreading mounting plate 41 is prevented from being transferred back to the electronic components of the main control board 42, thus helping to keep the temperature of the electronic components of the main control board 42 at a lower level.

[0045] In the appendix Figures 1 to 14 In this specific example of the side-scan sonar of the present invention, there are two main control boards 42. One main control board 42 is located on the lower layer and is defined as a lower plate 421, and the other main control board 42 is located on the upper layer and is defined as an upper plate 422. Along the thickness direction of the main control assembly 40, the lower plate 421 is suspended above the heat-spreading mounting plate 41, and a clearance cavity 401 is formed between the lower plate 421 and the heat-spreading mounting plate 41 to avoid electronic components of the lower plate 421. The upper plate 422 is suspended above the lower plate 421, and a clearance cavity 401 is formed between the upper plate 422 and the lower plate 421 to avoid electronic components of both the lower plate 421 and the upper plate 422.

[0046] Furthermore, the lower plate 421 and the upper plate 422 each have a plurality of plate through holes 420. The main control board 42 includes a plurality of lower studs 423 and a plurality of upper studs 424. One end of each lower stud 423 passes through the respective plate through holes 420 of the lower plate 421 and is screwed onto the boss 411 of the heat-spreading mounting plate 41 to lock the lower plate 421 onto the heat-spreading mounting plate 41. The boss 411 of the heat-spreading mounting plate 41 forms a clearance cavity 401 between the lower plate 421 and the heat-spreading mounting plate 41. One end of each upper stud 424 passes through the respective plate through holes 420 of the upper plate 422 and is screwed onto the respective lower stud 423. The lower stud 423 forms the clearance cavity 401 between the upper plate 422 and the lower plate 421.

[0047] Additionally, one end of some of the lower studs 423 can be directly screwed onto the boss 411 of the heat-spreading mounting plate 41, and one end of the upper stud 424 is screwed onto the lower stud 423 after passing through the module hole 431 of the power module 43, so as to mount the power module 43 onto the heat-spreading mounting plate 41, and form the clearance cavity 401 between the heat-spreading mounting plate 41 and the power module 43 to allow clearance for the electronic components of the power module 43.

[0048] Furthermore, in the appendix Figures 1 to 14 In this specific example of the side-scan sonar of the present invention, the main control component 40 includes a heat sink 44, which includes a first plate 441 and a second plate 442. One side of the first plate 441 and one side of the second plate 442 are mounted to each other. For example, a set of screws 1000 can be used to mount the first plate 441 and the second plate 442. The extending directions of the first plate 441 and the second plate 442 are perpendicular to each other, so that the first plate 441 and the second plate 442 are in an "L" shape. The first plate 441 is locked to each of the upper studs 424. For example, a set of screws 1000 can be used to lock the first plate 441 to each of the upper studs 424 so that the first plate 441 and the upper plate 422 are adjacent, and a clearance cavity 401 is formed between the first plate 441 and the upper plate 422 to avoid electronic components of the upper plate 422. The second plate 442 is stacked on the side wall of the cavity 11 of the cabin 10. For example, after the second plate 442 is stacked on the side wall of the cavity 11 of the cabin 10, a set of screws 1000 can be used to lock the second plate 442 and the cabin 10. In this way, the heat generated by the upper plate 422 during operation can be conducted to the cabin 10 through the first plate 441 and the second plate 442, and the cabin 10 dissipates the heat. The first plate 441 and the second plate 442 may be made of copper to improve the thermal conductivity of the heat sink 44.

[0049] Optionally, in other examples of the side-scan sonar of this utility model, the first plate 441 and the second plate 442 of the heat sink 44 can be integral, and the first plate 441 and the second plate 442 can be formed by bending a copper plate along a preset position.

[0050] Furthermore, the main control component 40 includes at least one heat-conducting copper pipe 45, which is L-shaped. One end of the heat-conducting copper pipe 45 is stacked on the first plate 441, and the other end is stacked on the second plate 442. The heat-conducting copper pipe 45 can quickly conduct heat from the first plate 441 to the second plate 442, thereby improving the heat dissipation capacity of the side-scan sonar. Preferably, the main control component 40 includes two heat-conducting copper pipes 45, which are arranged parallel to each other.

[0051] It is worth mentioning that the specific manner in which one end of the heat-conducting copper tube 45 is disposed on the first plate 441 and the other end is disposed on the second plate 442 is not limited in the side-scan sonar of this utility model. For example, in the attached Figures 1 to 14 In this specific example of the side-scan sonar of the present invention, one end of the heat-conducting copper tube 45 can be welded to the first plate 441 to stack this end of the heat-conducting copper tube 45 on the first plate 441, and the other end of the heat-conducting copper tube 45 can be welded to the second plate 442 to stack this end of the heat-conducting copper tube 45 on the second plate 442. Preferably, the first plate 441 has a first plate groove 4411, the second plate 442 has a second plate groove 442, the end of the heat-conducting copper tube 45 welded to the first plate 441 sinks into the first plate groove 4411 of the first plate 441, and the end of the heat-conducting copper tube 45 welded to the second plate 442 sinks into the second plate groove 4421 of the second plate 442.

[0052] Reference Appendix Figure 4 The main control component 40 includes a first pressure plate 46. The opposite ends of the first pressure plate 46 are respectively mounted on the second plate 442, and the first pressure plate 46 presses one end of the heat-conducting copper pipe 45 against the second plate 442. In this way, on the one hand, the first pressure plate 46 can prevent the end of the heat-conducting copper pipe 45 from detaching from the second plate 442; on the other hand, one side of the heat-conducting copper pipe 45 is in surface contact with the second plate 442, and the other side is in surface contact with the first pressure plate 46. Thus, a portion of the heat conducted by the heat-conducting copper pipe 45 is directly conducted to the second plate 442, and the other portion is conducted to the second plate 442 via the first pressure plate 46, and subsequently conducted to the cabin 10 for heat dissipation. This helps improve the heat dissipation capacity of the side-scan sonar. Preferably, the material of the first pressure plate 46 is aluminum or aluminum alloy. Preferably, the opposite ends of the first pressure plate 46 can be respectively mounted to the second plate 42 by a screw 1000.

[0053] Reference Appendix Figure 7 , Figure 9 and Figure 10 The main control component 40 includes a filter 47 and a second pressure plate 48. The second pressure plate 48 has a pressure plate groove 481, and the filter 47 is housed in the pressure plate groove 481 of the second pressure plate 48. The second pressure plate 48 is mounted on the heat-spreading mounting plate 41, and the filter 47 is connected to the main control board 42. The filter 47 can suppress noise and improve the signal clarity of the side-scan sonar. The second pressure plate 48 can conduct the heat generated by the filter 47 to the heat-spreading mounting plate 41, and then conduct it to the cabin 10 for heat dissipation. Preferably, the material of the second pressure plate 48 is aluminum or aluminum alloy. Preferably, the opposite ends of the second pressure plate 48 can be mounted to the heat-spreading mounting plate 41 by a screw 1000.

[0054] Continue to refer to the appendix Figure 7 , Figure 9 and Figure 10 The main control component 40 includes a third pressure plate 49. One end of the third pressure plate 49 is mounted to the heat-spreading mounting plate 41. For example, a set of screws 1000 can be used to mount this end of the third pressure plate 49 to the heat-spreading mounting plate 41. The other end of the third pressure plate 49 presses down on the electronic components (e.g., chips) of the main control board 42. In this way, the third pressure plate 49 can quickly conduct the heat generated by the electronic components of the main control board 42 to the heat-spreading mounting plate 41, and then conduct it to the cabin 10 for heat dissipation.

The first acquisition plate 62, the second acquisition plate 63, and the third acquisition plate 64 each have a plurality of plate holes 601. A set of screws 1000 can be used to install the assembly plate 61 onto the bottom wall of the cavity 11 of the cabin 10. The assembly plate 61 has a plurality of assembly posts 611, wherein each of the first... One end of a threaded post 67 is threaded onto the mounting post 611 of the mounting plate 61 after passing through the plate hole 601 of the first acquisition plate 62, so as to mount the first acquisition plate 62 on top of the mounting plate 61. The mounting post 611 of the mounting plate 61 provides a clearance space 69 between the mounting plate 61 and the first acquisition plate 62 to allow for the clearance of electronic components of the first acquisition plate 62. One end of the second threaded post 68 is threaded onto the first threaded post after passing through the plate hole 601 of the second acquisition plate 63. 67, so that the second acquisition board 63 is mounted above the first acquisition board 62, and the first acquisition board 62 and the second acquisition board 63 have the clearance space 69 for avoiding the electronic components of the first acquisition board 62 and the electronic components of the second acquisition board 63, wherein one end of the second screw post 68 is screwed onto the first screw post 67 after passing through the plate hole 601 of the third acquisition board 64, so that the third acquisition board 64 is mounted above the first acquisition board 62, and the first acquisition board 62 and the third acquisition board 63 have the clearance space 69 for avoiding the electronic components of the first acquisition board 62 and the electronic components of the second acquisition board 63, and the second acquisition board 63 has the clearance space 69 for avoiding the electronic components of the first acquisition board 62 and the second acquisition board 63, and the second acquisition board 64 ...
