Description

Technical Field

[0001] The present invention relates to a sonar, and particularly to a sonar with a pressure sensor. Background Art

[0002] In many fields such as current ocean exploration, underwater monitoring, and navigation, sonar technology plays a crucial role. Existing sonars mainly focus on detecting targets by utilizing the propagation characteristics of sound waves in water, such as detecting submarines, fish schools, and seabed topography. However, with the continuous expansion and in-depth development of these application scenarios, higher requirements are put forward for the accuracy and comprehensiveness of the information obtained by sonar systems. In the marine environment, depth information is an indispensable important parameter. Whether it is for marine scientific research to understand the water temperature, salinity, water flow velocity, and marine biological community distribution at different depth layers, or for ensuring navigation safety to determine the precise water depth below the ship to avoid dangers such as running aground, depth data is of extremely important significance. However, existing sonars often lack a direct and accurate depth measurement function and can only rely on some indirect methods or additionally equipped with other independent depth measurement devices to obtain depth information. This not only increases the complexity, cost, and installation space of the equipment, but also is prone to errors and delays in data integration and synchronization. Summary of the Invention

[0042] Before elaborating in detail any embodiment of the present invention, it should be understood that the present invention in its application is not limited to the details of the construction and arrangement of the components set forth in the following description or illustrated in the following drawings. The present invention is capable of other embodiments and of being practiced or carried out in various ways. Additionally, it should be understood that the terminology and phrases used herein are for the purpose of description and should not be regarded as limiting. As used herein, "including" or "having" and their variants are intended to cover the listed items and their equivalents as well as additional items. Unless otherwise specified or limited, the terms "mounted", "connected", "supported" and "coupled" and their variants are used broadly and cover both direct and indirect mounting, connection, support and coupling. Further, "connected" and "coupled" are not limited to physical or mechanical connection or coupling

[0043] And, on the one hand, in the disclosure of the present invention, the orientation or positional relationship indicated by terms such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so the above terms should not be construed as limiting the present invention; on the other hand, the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple, and the term "a" should not be construed as limiting the quantity

[0044] Referring to the attached drawings of the specification of the present invention Figures 1 to 20 According to a preferred embodiment of the present invention, a sonar with a pressure sensor will be disclosed and elaborated in the following description, wherein the sonar includes a sonar body 10 and a pressure sensor 20 mounted on the sonar body 10. When the sonar enters the water and the sonar body 10 detects underwater by emitting and receiving acoustic wave signals, the pressure sensor 20 can measure the current depth of the sonar by measuring the water pressure, so that the sonar can obtain more accurate and comprehensive data of the detected area

[0045] Preferably, the sonar body 10 has an assembly groove 101, and the pressure sensor 20 is installed in the assembly groove 101 of the sonar body 10. In this way, the pressure sensor 20 may not protrude from the surface of the sonar body 10, so that when the sonar moves in the water, the pressure sensor 20 will not affect the acoustic performance of the sonar. For example, the pressure sensor 20 will not cause bubbles to be generated in the surrounding environment of the sonar, so that the sound wave signal emitted by the sonar body 10 only needs to pass through one medium (i.e., water) to radiate toward the direction of the detected area, and the reflected sound wave from the detected area only needs to pass through one medium (i.e., water) to be received by the sonar body 10, thereby ensuring the accuracy of the detection result of the sonar on the detected area.

[0046] Reference Figures 1 to 5 , Figure 7 , Figures 9 to 16 The sonar body 10 includes a cabin 11, a watertight terminal 12, a transceiver array assembly 13 and a circuit board assembly 14. The cabin 11 has a cabin cavity 111 and a terminal channel 112, and the terminal channel 112 is connected to the cabin cavity 111. The watertight terminal 12 is watertightly installed in the terminal channel 112 of the cabin 11, one end of the watertight terminal 12 extends to the cabin cavity 111 of the cabin 11 to form the inner end of the watertight terminal 12, and one end of the watertight terminal 12 extends to the outside of the cabin 11 to form the outer end of the watertight terminal 12. The transceiver array assembly 13 is installed in the cabin 11, and the transceiver array assembly 13 closes the cavity of the cabin cavity 111 of the cabin 11, so that the cabin cavity 111 of the cabin 11 forms a watertight environment. The circuit board assembly 14 is installed in the transceiver array assembly 13, and the circuit board assembly 14 is accommodated in the cabin cavity 111 of the cabin body 11, so that the circuit board assembly 14 is maintained in a watertight environment. The inner end of the watertight terminal 12 is connected to the circuit board assembly 14. The assembly groove 101 of the sonar body 10 is formed in the transceiver array assembly 13, so that the pressure sensor 20 is installed in the transceiver array assembly 13. Optionally, in other examples of the sonar of the present invention, the assembly groove 101 of the sonar body 10 can also be formed in the cabin body 11, so that the pressure sensor 20 is installed in the cabin body 11.

[0047] Reference Figure 4 , Figure 5 , Figure 7 , Figures 13 to 16, the transceiver array assembly 13 further includes a top cover 131, a vulcanized part 132, a receiving array 133, and a transmitting array 134. Wherein, the vulcanized part 132 is vulcanized to the top cover 131, and the vulcanized part 132 is combined with the receiving array 133 during the vulcanization process, so that the top cover 131, the vulcanized part 132, and the receiving array 133 are combined into an integral body. The transmitting array 134 is installed on the top cover 131, and the top cover 131 is installed on the cabin body 11 and used to close the opening of the cabin cavity 111. That is to say, in this specific example of the sonar of the present invention, the transmitting array 134 is installed on the top cover 131 after the vulcanized part 132 is formed, which makes the transmitting array 134 detachable. Thus, when the transmitting array 134 is damaged, only the new transmitting array 134 needs to be replaced to complete the repair of the sonar. When the receiving array 133 is damaged, the transmitting array 134 can be reused, thereby avoiding waste and reducing the maintenance cost of the sonar.

[0048] Refer to the appendix Figure 4 and Figure 5 , the assembly groove 101 of the sonar body 10 is formed on the top cover 131. Therefore, in this specific example of the sonar of the present invention, the pressure sensor 20 is installed on the top cover 131. Preferably, the assembly groove 101 of the sonar body 10 is located below the transmitting array 134. In this way, the pressure sensor 20 is located below the transmitting array 134. By this means, on the one hand, the pressure sensor 20 is hidden by the top cover 131 and the transmitting array 134 to avoid the exposure of the pressure sensor 20 to protect the pressure sensor 20. On the other hand, the setting of the pressure sensor 20 will not affect the overall appearance of the sonar, so that the pressure sensor 20 will not affect the acoustic performance of the sonar.

[0049] Preferably, the assembly groove 101 of the sonar body 10 has a receiving groove 1011 and an assembly through hole 1012 extending from the receiving groove 1011 to the lower surface of the top cover 131. The inner diameter of the assembly through hole 1012 is smaller than that of the receiving groove 1011. The pressure sensor 20 includes a sensor body 21 and an assembly cylinder 22 extending downward from the sensor body 21. The outer diameter of the sensor body 21 is larger than the inner diameter of the assembly through hole 1012 of the sonar body 10. After the assembly cylinder 22 of the pressure sensor 20 extends through the assembly through hole 1012 to the lower side of the top cover 131, the sensor body 21 is received in the receiving groove 1011 of the sonar body 10. The sonar further includes a nut 30, and the nut 30 is screwed onto the part of the assembly cylinder 22 protruding below the top cover 131. In this way, the nut 30 and the sensor body 21 cooperate with each other to mount the pressure sensor 20 on the top cover 131.

[0050] The sonar further includes at least one sealing ring 40. The sealing ring 40 is clamped between the sensor body 21 and the top cover 131, and the sensor body 21 and the top cover 131 clamp and deform the sealing ring 40 to increase the watertightness of the installation position of the pressure sensor 20 and the top cover 131 by the sealing ring 40.

[0051] Preferably, the top cover 131 has a groove 1310, and the bottom of the transmitting array 134 sinks into the groove 1310 of the top cover 131, which is beneficial to reducing the height dimension of the sonar and thus beneficial to the miniaturization of the sonar. After the transmitting array 134 is installed on the top cover 131 in such a way that the bottom of the transmitting array 134 sinks into the groove 1310 of the top cover 131, a water flow channel 102 is formed between the sonar body 10, the top cover 131 and the transmitting array 134. After the sonar is put into water, the water is allowed to reach the pressure sensor 20 through the water flow channel 102 of the sonar body 10, so that the pressure sensor 20 measures the current depth of the sonar by measuring the water pressure.

[0052] Refer to the appendix Figures 1 to 5 、 Figure 7 、 Figures 9 to 16The top cover 131 has at least one front plate through hole 1311, which passes through the top and bottom of the top cover 131. The receiving array 133 has at least one front plate 1331. The top of the front plate 1331 extends from the bottom of the top cover 131 to the top through the front plate through hole 1311 of the top cover 131, wherein the vulcanized portion 132 is vulcanized on the top of the top cover 131, and the vulcanized portion 132 wraps the top of the front plate 1331, so that the top cover 131, the vulcanized portion 132 and the receiving array 133 are combined into a whole.

[0053] Furthermore, the top cover 131 has a cover ring 1312 and a baffle 1313, the cover ring 1312 and the baffle 1313 are respectively located at the rear side and the front side of the groove 1310 of the top cover 131, and after the emitting array 134 is installed on the top cover 131 in a manner that the bottom of the emitting array 134 sinks into the groove 1310 of the top cover 131, the cover ring 1312 and the baffle 1313 are respectively located at the rear side and the front side of the emitting array 134 to protect the emitting array 134 and avoid the emitting array 134 from being collided as much as possible. The cover ring 1312 surrounds the top of the front plate 1331, and the vulcanization part 132 is formed inside the cover ring 1312 of the top cover 131. Preferably, the shape and size of the baffle 1313 of the top cover 131 are consistent with the shape and size of the portion of the transmitting array 134 that is not sunken into the groove 1310 of the top cover 131. In this way, the baffle 1313 of the top cover 131 can not only protect the transmitting array 134, but also prevent the sound wave signal from being emitted outward by the transmitting array 134.

[0054] Reference Figure 1 , Figure 5 , Figure 7 , Figure 10 , Figure 11 and Figure 13, the top cover 131 further has two inclined surfaces 1314. The two inclined surfaces 1314 extend outwardly and obliquely from opposite sides of the groove 1310 of the top cover 131, and the included angle formed between the extending directions of the two inclined surfaces 1314 is an obtuse angle. That is to say, one of the inclined surfaces 1314 is respectively provided on opposite sides of the transmitting array 134. In this way, when the sonar moves in water, the inclined surfaces 1314 of the top cover 131 can push the water flow to both sides of the transmitting array 134, avoiding the generation of tiny bubbles on opposite sides of the transmitting array 134, ensuring that the acoustic wave signal emitted by the transmitting array 134 only needs to pass through one medium (i.e., water) and radiate towards the detected area, and the reflected acoustic wave from the detected area only needs to pass through one medium (i.e., water) to be received by the receiving array 133, thereby ensuring the accuracy of the detection result of the sonar for the detected area. At the same time, the transmitting array 134 can have a larger field of view angle to avoid interference. Preferably, the two inclined surfaces 1314 of the top cover 131 are symmetric with each other.

[0055] Refer to the attached Figure 5 and Figure 6 , the top cover 131 has a wire through-hole 1315. The wire through-hole 1315 extends from the bottom of the groove 1310 to the lower surface of the top cover 131, that is, the wire through-hole 1315 of the top cover 131 penetrates above and below the top cover 131. The cable of the transmitting array 134 extends to the cavity 111 of the cabin body 11 after passing through the wire through-hole 1315 of the top cover 131, so that the cable of the transmitting array 134 can be connected to the circuit board assembly 14.

[0056] Refer to the attached Figure 5 and Figure 6, the top cover 131 has at least one top cover screw hole 1316, the transmitting array 134 has at least one array body threaded hole 1341, the array body threaded hole 1341 of the transmitting array 134 corresponds to the top cover screw hole 1316 of the top cover 131, the sonar body 10 includes at least one screw 15, the threaded end of the screw 15 extends to the array body threaded hole 1341 of the transmitting array 134 after passing through the top cover screw hole 1316 of the top cover 131, and the threaded end of the screw 15 is screwed onto the transmitting array 134, so that the transmitting array 134 is mounted on the top cover 131. It can be understood that after the threaded end of the screw 15 exits the array body threaded hole 1341 of the transmitting array 134, the transmitting array 134 is detachable. That is to say, in this specific example of the sonar of the present invention, the top cover 131, the vulcanized part 132 and the receiving array 133 are combined into a whole, the transmitting array 134 is mounted on the top cover 131, so that when the receiving array 133 is damaged, the transmitting array 134 can be reused, and when the transmitting array 134 is damaged, replacing the new transmitting array 134 can complete the repair of the sonar, so that the repair difficulty and cost of the sonar can be reduced, and the waste of accessories can be avoided. Preferably, a sealing ring 40 is provided between the transmitting array 134 and the top cover 131 to increase the watertightness of the installation position of the transmitting array 134 and the top cover 131. In a specific example of the sonar of the present invention, the number of the top cover screw holes 1316 of the top cover 131 is two, and the two top cover screw holes 1316 are located on opposite sides of the wire through hole 1315 of the top cover 131. Correspondingly, the number of the array body threaded holes 1341 of the transmitting array 134 is two, the two array body threaded holes 1341 of the transmitting array 134 correspond to the two top cover screw holes 1316 of the top cover 131 respectively, and the threaded ends of the two screws 15 extend to the two array body threaded holes 1341 of the transmitting array 134 after passing through the two top cover screw holes 1316 of the top cover 131 respectively, so that the transmitting array 134 can be reliably mounted on the top cover 131.

[0057] It can be understood that during the process of vulcanizing the vulcanized part 132 on the top of the top cover 131, the receiving array 133 may be slightly tilted, and the tilt amount can be obtained by measuring after powering on the sonar. During the process of installing the transmitting array 134, the tilt amount of the transmitting array 134 can be finely adjusted so that the receiving array 133 and the transmitting array 134 are adapted to each other, thereby ensuring the performance of the sonar.

[0058] Refer to the appendix Figure 5 and Figure 6, the top cover 131 has a positioning groove 13113 which is recessed from one side of the groove 1310. The transmitting array 134 has a positioning projection 1340 at the bottom of the transmitting array 134. When a part of the transmitting array 134 sinks into the groove 1310 of the top cover 131, the positioning projection 1340 of the transmitting array 134 extends into the positioning groove 13113 of the top cover 131, thus preventing the installation direction of the transmitting array 134 from being reversed and achieving the "anti-fooling" assembly of the transmitting array 134. Preferably, the size of the positioning groove 13113 of the top cover 13 is slightly larger than the size of the positioning projection 1340 of the transmitting array 134, so that during the installation of the transmitting array 134, the inclination of the transmitting array 134 can be finely adjusted to make the receiving array 133 and the transmitting array 134 match, thereby ensuring the performance of the sonar.

[0059] Reference appendix Figure 4 , in the middle of the front side of the cabin body 11, there is a terminal slot 113 and a terminal mounting platform 114. The slot opening of the terminal slot 113 faces outward. The terminal channel 112 is arranged on the terminal mounting platform 114, and the terminal channel 112 communicates with the cabin cavity 111 and the terminal slot 113. The watertight terminal 12 is installed on the terminal mounting platform 114 of the cabin body 11, and the outer end of the watertight terminal 12 is located in the terminal slot 113 of the cabin body 11. By arranging the terminal slot 113 on the front side of the cabin body 11, the sonar can prevent the outer end of the watertight terminal 12 from protruding from the front side of the cabin body 11. Thus, when transporting the sonar, the space occupied by the sonar can be reduced. And by preventing the outer end of the watertight terminal 12 from being collided, not only the reliability of the connection relationship between the watertight terminal 12 and the circuit board assembly 14 can be ensured, but also the watertightness of the installation position of the watertight terminal 12 and the cabin body 11 can be ensured.

[0060] Preferably, continue to refer to appendix Figure 4, the terminal mounting table 114 of the cabin body 11 extends obliquely, having an acute angle with the horizontal plane. In this way, there is an acute angle between the extending direction of the watertight terminal 12 and the height direction of the sonar. By this means, not only can the space of the cabin cavity 111 of the cabin body 11 be saved, but also the space of the cabin cavity 111 of the cabin body 11 can be made more regular, which is conducive to making full use of the cabin cavity 111 of the cabin body 11. Moreover, by arranging the watertight terminal 12 obliquely, when connecting the watertight terminal 12 and a cable of equipment such as a ship or a submarine, it is not only convenient to manually tighten the screw nut for connecting the watertight terminal 12 and the cable, but also after the sonar is installed in the application environment, it can avoid the problem that the connection position between the cable and the watertight terminal 12 is prone to being stressed and broken due to the need for the cable to extend horizontally.

[0061] It can be understood that the angle formed between the extending direction of the watertight terminal 12 and the height direction of the sonar should neither be too small nor too large. If the angle formed between the extending direction of the watertight terminal 12 and the height direction of the sonar is too small, the watertight terminal 12 tends to be vertically arranged, resulting in the unobvious above-mentioned beneficial effects of the obliquely arranged watertight terminal 12. If the angle formed between the inclined direction of the watertight terminal 12 and the height direction of the sonar is too large, the watertight terminal 12 tends to be horizontally arranged, which will also lead to the unobvious above-mentioned beneficial effects of the obliquely arranged watertight terminal 12. Therefore, in the sonar of the present invention, in order to ensure that the obliquely arranged watertight terminal 12 obviously has the above-mentioned beneficial effects, the angle formed between the extending direction of the watertight terminal 12 and the height direction of the sonar is preferably not less than 15° and not more than 30°. That is, the suitable value range of the angle formed between the extending direction of the watertight terminal 12 and the height direction of the sonar is 15° - 30°.

[0062] Refer to the appendix Figure 7 、 Figure 8 、 Figure 15 and Figure 16, at least one preamplifier chip 1332 is mounted on the bottom of the preamplifier board 1331 of the receiving array 133. The top cover 131 has at least one abutting platform 1317. The abutting platform 1317 extends downward from the edge of the preamplifier board through-hole 1311. And the abutting platform 1317 has an abutting inclined surface 13170. The preamplifier chip 1332 mounted on the bottom of the preamplifier board 1331 and the abutting inclined surface 13170 of the abutting platform 1317 are arranged adjacent to each other and are offset in the horizontal direction. The sonar body 10 further includes at least one pressing component 17. The pressing component 17 includes at least one pressing piece 171 and an assembly arm 172. The pressing piece 171 is arranged at the end of the assembly arm 172. The pressing piece 171 has a pressing plane 1711. The assembly arm 172 has a driven inclined surface 1721. Wherein the assembly arm 172 is mounted on the top cover 131. The pressing plane 1711 of the pressing piece 171 abuts against the preamplifier chip 1332 on the bottom of the preamplifier board 1331. The driven inclined surface 1721 of the assembly arm 172 abuts against the abutting inclined surface 13170 of the abutting platform 1317. In this way, the heat generated by the preamplifier chip 1332 on the bottom of the preamplifier board 1331 during operation can be conducted to the top cover 131 through the pressing component 17 and dissipated through the top cover 131. Since the peripheral wall of the top cover 131 is exposed and has a large area, the sonar has a good heat dissipation effect. Optionally, in other examples of the sonar of the present invention, the preamplifier chip 1332 mounted on the bottom of the preamplifier board 1331 and the abutting inclined surface 13170 of the abutting platform 1317 can also be arranged face to face.

[0063] In a specific example of the sonar of the present invention, the edge of the preamplifier board through-hole 1311 of the top cover 131 has two abutting platforms 1317 extending downward. The bottom of the preamplifier board 1331 has two preamplifier chips 1332. Correspondingly, the pressing component 17 includes two pressing pieces 171 and one assembly arm 172. One pressing piece 171 is arranged at each of the opposite ends of the assembly arm 172. The pressing plane 1711 of each pressing piece 171 abuts against each preamplifier chip 1332 on the bottom of the preamplifier board 1331.

[0064] In a specific example of the sonar of the present invention, the top cover 131 has two front amplifier board perforations 1311, the receiving array 133 has two front amplifier boards 1331, the tops of the respective front amplifier boards 1331 extend from the bottom to the top of the top cover 131 through the respective front amplifier board perforations 1311 of the top cover 131, wherein the vulcanized part 132 is vulcanized on the top of the top cover 131, and the vulcanized part 132 wraps the tops of the respective front amplifier boards 1331, so that the top cover 131, the vulcanized part 132 and the receiving array 133 are combined into an integral body. It can be understood that in this embodiment of the sonar, the number of the pressing components 17 is two.

[0065] Refer to the attached Figure 15 and Figure 16 , the top cover 131 has at least one first threaded hole 1318, the assembly arm 172 has at least one first screw hole 1722, the first screw hole 1722 of the assembly arm 172 corresponds to the first threaded hole 1318 of the top cover 131, wherein the threaded end of the screw 15 extends to the first threaded hole 1318 of the top cover 131 after passing through the first screw hole 1722 of the assembly arm 172 to mount the assembly arm 172 on the top cover 131. In a specific example of the sonar of the present invention, the number of the first threaded holes 1318 of the top cover 131 is two, correspondingly, the number of the first screw holes 1722 of the assembly arm 172 is two, and the threaded ends of the two screws 15 extend to the two first threaded holes 1318 of the top cover 131 after passing through the two first screw holes 1722 of the assembly arm 172 respectively, so as to prevent the assembly arm 172 from tilting, so that the pressing planes 1711 of the two pressing pieces 171 are respectively closely attached to the two front amplifier board chips 1332 at the bottom of the front amplifier board 1331.

[0066] The process of installing the pressing component 17 can be as follows: First, allow the threaded end of the screw 15 to align with the first threaded hole 1318 of the top cover 131 after passing through the first screw hole 1722 of the assembly arm 172. At this time, the driven inclined surface 1721 of the assembly arm 172 fits against the abutting inclined surface 13170 of the abutting platform 1317, and each pressing piece 171 is adjacent to each front placement board chip 1332 at the bottom of the front placement board 1331. Second, rotate the screw 15 to allow the threaded end of the screw 15 to extend into the first threaded hole 1318 of the top cover 131 in a screwed manner. As the screwed depth of the screw 15 changes, the screw 15 pushes the pressing component 17 to move upward. In this process, the driven inclined surface 1721 of the assembly arm 172 and the abutting inclined surface 13170 of the abutting platform 1317 cooperate with each other to drive the pressing component 17 to move in the direction close to the front placement board chip 1332 at the bottom of the front placement board 1331, so that the pressing plane 1711 of each pressing piece 171 is closely attached to each front placement board chip 1332. Preferably, a thermal conductive silicone grease can be provided between the pressing plane 1711 of the pressing piece 171 and the front placement board chip 1332.

[0067] The front placement board chip 1332 at the bottom of the front placement board 1331 is a chip for receiving and processing acoustic signals. In this way, the circuit board assembly 14 of the present invention may not need to be provided with a receiving circuit board. In other words, in this specific example of the sonar of the present invention, the chip of the receiving circuit board in the traditional sonar is integrated into the front placement board 1331 to form the front placement board chip 1332, so that the sonar of the present invention can omit the receiving circuit board, which is beneficial to reducing the cost of the sonar and making the sonar miniaturized and lightweight. At the same time, on the one hand, since the chip for receiving and processing acoustic signals is integrated into the front placement board 1331 to form the front placement board chip 1332, the front placement board chip 1332 can be adjacent to the top cover 131, so that the heat generated by the front placement board chip 1332 during operation can be quickly conducted to the top cover 131 through the pressing component 17 and dissipated through the top cover 131. On the other hand, since the chip for receiving and processing acoustic signals is integrated into the front placement board 1331 to form the front placement board chip 1332, the heat sources of the sonar are dispersed, which is beneficial to the heat dissipation of the sonar.

[0068] In addition, referring to the attached Figure 4 and Figure 7, the top of the pre-amplifier board 1331 is provided with the pre-amplifier board chips 1332, and these pre-amplifier board chips 1332 are wrapped by the vulcanized part 132. The transceiver array assembly 13 further includes at least one array body heat sink 135. The top of the array body heat sink 135 is stacked on the pre-amplifier board chips 1332 on the top of the pre-amplifier board 1331. The bottom of the array body heat sink 135 extends to the top cover 131. The heat generated by the pre-amplifier board chips 1332 on the top of the pre-amplifier board 1331 during operation is conducted to the top cover 131 through the array body heat sink 135 and dissipated through the top cover 131. It can be understood that the vulcanized part 132 can wrap the top of the array body heat sink 135 so that the array body heat sink 135 is reliably stacked on the pre-amplifier board chips 1332 on the top of the pre-amplifier board 1331. Optionally, the whole of the array body heat sink 135 can be wrapped by the vulcanized part 132.

[0069] Refer to the appendix Figure 4 、 Figures 9 to 14 、 Figures 17 to 20 , the circuit board assembly 14 includes a module rack 141, a main control board 142 and a transmitting board 143. The main control board 142 and the transmitting board 143 are installed on the module rack 141 at intervals, and the transmitting board 143 is connected to the main control board 142. The module rack 141 is installed on the top cover 131, the main control board 142 and the pre-amplifier board 1331 are connected. When the top cover 131 is installed on the cabin body 11, the top cover 131 houses the circuit board assembly 14 in the cabin cavity 111 of the cabin body 11.

[0070] That is to say, in this specific example of the sonar of the present invention, the main control board 142 and the transmitting board 143 are not directly installed on the cabin body 11. Instead, the main control board 142 and the transmitting board 143 are first installed on the module rack 141, and then the module rack 141 is installed on the top cover 131. When the top cover 131 is installed on the cabin body 11, the circuit board assembly 14 is received in the cabin cavity 111 of the cabin body 11 by the top cover 131. In this way, the connection operations of the main control board 142 and the transmitting board 143, and the connection operation of the main control board 142 and the preamplifier board 1331 can be carried out outside the cabin cavity 111 of the cabin body 11, so that the connection operations of the main control board 142 and the transmitting board 143, and the connection operation of the main control board 142 and the preamplifier board 1331 do not need to be carried out in a narrow space, which is convenient for assembling the sonar. In the sonar of the present invention, the circuit board assembly 14 does not include a receiving circuit board to reduce the number of circuit boards. In this way, it is beneficial to reduce the cost of the sonar and reduce the size of the sonar, so that the sonar can be miniaturized and lightened.

[0071] In addition, the module rack 141 can be made of materials with good thermal conductivity, such as copper, aluminum, copper alloy, aluminum alloy, etc. Since the main control board 142 and the transmitting board 143 are installed on the module rack 141 and the module rack 141 is installed on the top cover 131, the heat generated by the main control board 142 and the transmitting board 143 during operation can be quickly conducted to the top cover 131 through the module rack 141 and dissipated through the top cover 131. Preferably, the bottom of the module rack 141 is in surface contact with the cabin body 11. In this way, the heat generated by the main control board 142 and the transmitting board 143 during operation can also be quickly conducted to the cabin body 11 through the module rack 141 and dissipated through the cabin body 11.

[0072] Continue to refer to the appendix Figures 17 to 20 The module rack 141 includes a rack bottom plate 1411, a rack vertical plate 1412 and at least one isolation and locking portion 1413.

In this specific example of the sonar of the present invention, one third screw hole 1421 is respectively arranged at the four corners of the frame vertical plate 1412, one third screw hole 1421 is respectively arranged at the four corners of the main control board 142, correspondingly, the number of the isolation locking parts 1413 is four, so that the four isolation locking parts 1413 reliably install the main control board 142 on the module frame 141.

[0075] Preferably, the frame vertical plate 1412 has a vertical plate boss 14123, the main control board 142 has a main control board chip 1422, and the main control board chip 1422 of the main control board 142 is attached to the vertical plate boss 14123 of the frame vertical plate 1412. In this way, the heat generated by the main control board chip 1422 of the main control board 142 during operation can be directly conducted to the frame vertical plate 1412. Preferably, there is thermal grease between the vertical plate boss 14123 of the frame vertical plate 1412 and the main control board chip 1422 of the main control board 142.

[0076] The isolation locking part 1413 has a fourth threaded hole 14133 which is arranged in the isolation section 14131. The transmitting board 143 has at least one fourth screw hole 1431. The inner diameter dimension of the fourth screw hole 1431 of the transmitting board 143 is smaller than the outer diameter dimension of the isolation section 14131 of the isolation locking part 1413. The transmitting board 143 is arranged on one side of the main control board 142. The fourth screw hole 1431 of the transmitting board 143 corresponds to the fourth threaded hole 14133 of the isolation locking part 1413. The threaded end of the screw 15 extends to the fourth threaded hole 14133 of the isolation locking part 1413 after passing through the fourth screw hole 1431 of the transmitting board 143, and the threaded end of the screw 15 is screwed to the isolation locking part 1413. In this way, the transmitting board 143 is installed on the module frame 141, and the transmitting board 143 and the main control board 142 are spaced apart from each other. In this specific example of the sonar of the present invention, each corner of the transmitting board 143 is respectively provided with a fourth screw hole 1431. In this way, the four screws 15 reliably install the transmitting board 143 on the module frame 141.

[0077] Continue to refer to the attached Figure 19 and Figure 20 The main control board 142 has a main control board connector 1423, and the transmitting board 143 has a transmitting board connector 1432. The main control board connector 1423 of the main control board 142 and the transmitting board connector 1432 of the transmitting board 143 cooperate with each other to conduct the main control board 142 and the transmitting board 143. In this way, there is no need for flying wires between the main control board 142 and the transmitting board 143, which can not only avoid the problem of the solder joints of the flying wires being desoldered during the assembly of the sonar, but also avoid the problem of the actual performance of the sonar decreasing due to poor solder joint consistency.

[0078] Refer to the attached Figure 17 and Figure 19, the transmitting board 143 has a transmitting board chip 1433, the module holder 141 includes a holder heat conducting sheet 1414, the holder heat conducting sheet 1414 is installed on one side of the holder bottom plate 1411, and the holder heat conducting sheet 1414 is stacked on the transmitting board chip 1433 of the transmitting board 143. In this way, the heat generated by the transmitting board chip 1433 of the transmitting board 143 during operation is conducted to the cabin 11 through the holder heat conducting sheet 1414 and the holder bottom plate 1411, and is dissipated through the cabin 11. Preferably, a heat conducting silicone grease is provided between the transmitting board chip 1433 of the transmitting board 143 and the holder heat conducting sheet 1414.

[0079] Specifically, the holder bottom plate 1411 has at least one seventh screw hole 14112, the holder heat conducting sheet 1414 has at least one seventh threaded hole 14141, the seventh threaded hole 14141 of the holder heat conducting sheet 1414 corresponds to the seventh screw hole 14112 of the holder bottom plate 1411. The threaded end of the screw 15 extends to the seventh threaded hole 14141 of the holder heat conducting sheet 1414 after passing through the seventh screw hole 14112 of the holder bottom plate 1411, and the holder heat conducting sheet 1414 is installed on one side of the holder bottom plate 1411 by the screw 15. In this specific example of the sonar of the present invention, the holder bottom plate 1411 has two seventh screw holes 14112, and the holder heat conducting sheet 1414 has two seventh threaded holes 14141. In this way, the two screws 15 are used to reliably install the holder heat conducting sheet 1414 on the holder bottom plate 1411.

[0080] Refer to the attached Figures 9 to 12 , Figures 17 to 20 , the holder vertical plate 1412 of the module holder 141 is installed on the top cover 131 to install the module holder 141 on the top cover 131.

[0081] Specifically, opposite sides of the top of the vertical plate 1412 of the module holder 141 each have an extension arm 14124. The vertical plate 1412 of the module holder further has two fifth screw holes 14125, and each of the extension arms 14124 is provided with one of the fifth screw holes 14125. Opposite sides of the top cover 131 each have a fifth threaded hole 1319. Each of the fifth threaded holes 1319 of the top cover 131 corresponds to the fifth screw holes 14125 of the vertical plate 1412 of the module holder. The threaded ends of the two screws 15 extend to the two fifth threaded holes 1319 of the top cover 131 after passing through the two fifth screw holes 14125 of the vertical plate 1412 of the module holder, and the threaded ends of the screws 15 are screwed to the top cover 131, and the module holder 141 is mounted on the top cover 131 by the screws 15.

[0083] The extending direction of the front preamplifier board 1331 is the same as that of the main control board 142, and the main control board 142 is located below the front preamplifier board 1331. Since the sonar needs to be miniaturized, the distance between the top of the main control board 142 and the bottom of the front preamplifier board 1331 is relatively small. Limited by the connection relationship between the main control board 142 and the flexible cable 18, and between the front preamplifier board 1331 and the flexible cable 18, if the main control board cable head 1424 of the main control board 142 is directly below the front preamplifier board cable head 13311 of the front preamplifier board 1331, then during the installation of the top of the frame vertical plate 1412 onto the top cover 131, the first cable head 181 and the second cable head 182 of the flexible cable 18 are horizontally stressed, resulting in loosening or even detachment of the first cable head 181 and the second cable head 182 of the flexible cable 18. In this specific example of the sonar of the present invention, the front preamplifier board cable head 13311 of the front preamplifier board 1331 and the main control board cable head 1424 of the main control board 142 are misaligned in the horizontal direction, so that the front preamplifier board cable head 13311 and the main control board cable head 1424 have a greater distance, thereby avoiding the horizontal stress on the first cable head 181 and the second cable head 182 of the flexible cable 18 during the installation of the top of the frame vertical plate 1412 onto the top cover 131, and ensuring the reliability of the connection relationship between the first cable head 181 of the flexible cable 18 and the front preamplifier board cable head 13311 of the front preamplifier board 1331, as well as ensuring the reliability of the connection relationship between the second cable head 182 and the main control board cable head 1424 of the main control board 142.

The threaded ends of the respective screws 15 extend to the respective sixth threaded holes 13110 of the top cover 131 after passing through the respective sixth screw holes 1441 of the power supply board 144, so that the respective screws 15 reliably mount the power supply board 144 on the top cover 131.

[0086] By mounting the power supply board 144 on the top cover 131, on the one hand, the sonar can disperse the heat source, and on the other hand, the heat generated by the power supply board 144 during operation can be directly conducted to the top cover 131 and dissipated through the top cover 131, thereby improving the heat dissipation efficiency of the sonar.

Therefore, even without a shielding layer, the sonar can have a good electromagnetic shielding function.
