[0031] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 12 A self-starting underwater communication device testing device 1000 (hereinafter referred to as "testing device 1000") according to a preferred embodiment of the present invention will be disclosed and described in the following description. A transceiver 2000 can be installed in the testing device 1000, and one transceiver 2000 and an underwater communication device 3000 can be connected to the testing device 1000 via a three-way watertight cable 4000. The testing device 1000 can press and release the button 2001 of the transceiver 2000 to start the underwater communication device 3000 in an underwater environment, thereby enabling the testing device 1000 to test the underwater communication device 3000 in a real underwater environment.

[0032] Specifically, the detection device 1000 includes a housing 10, a controller 20, two batteries 30, a pressure sensor 40, at least one electromagnet 50, at least one watertight terminal 60, and a bracket 70.

[0033] Specifically, the outer casing 10 includes a bottom shell 11 and a top cover 12. The bottom shell 11 has a cavity 111, at least one rod hole 112, at least one first terminal hole 113, and a mounting hole 114. The rod hole 112, the first terminal hole 113, and the mounting hole 114 respectively communicate with the cavity 111 and the external environment. The top cover 12 is mounted on the bottom shell 11 and closes the opening of the cavity 111 of the bottom shell 11, thereby creating a watertight environment within the cavity 111. (See attached...) Figures 1 to 12 In this specific example of the detection device 1000 of the present invention shown, a set of screws 80 can be used to lock the top cover 12 to the bottom shell 11 so that the top cover 12 is securely installed on the bottom shell 11.

[0034] In the appendix Figures 1 to 12 In this specific example of the detection device 1000 of the present invention shown, the bottom shell 11 and the top cover 12 can be formed from an aluminum substrate by a milling process to increase the pressure resistance of the detection device 1000.

[0035] Preferably, the outer casing 10 further includes a deformable gasket 13, which may be made of rubber. The gasket 13 is clamped between the bottom casing 11 and the top cover 12, and the bottom casing 11 and the top cover 12 cause the gasket 13 to deform slightly so that the gasket 13 ensures the water tightness of the mounting position of the bottom casing 11 and the top cover 12.

[0036] Preferably, the rod hole 112 and the first terminal hole 113 are located on different sides of the bottom housing 11 to facilitate the installation of the transceiver 2000 and one end of the three-way watertight cable 4000. For example, in the attached Figures 1 to 12 In this specific example of the detection device 1000 of the present invention shown, the rod hole 112 and the first terminal hole 113 are located on opposite sides of the bottom shell 11, so that the transceiver 2000 can be installed on one side of the bottom shell 11, and one end of the three-way watertight cable 4000 can be connected to the detection device 1000 on the opposite side of the bottom shell 11. In this way, the detection device 1000 can effectively avoid the problem of mutual interference between the transceiver 2000 and this end of the three-way watertight cable 4000.

[0037] The controller 20 is disposed within the cavity 111 of the bottom shell 11 to maintain the controller 20 in a watertight environment. Specifically, in the attached... Figures 1 to 12In this specific example of the detection device 1000 of the present invention shown, the housing 10 includes a suspension frame 14, which is locked to the bottom wall of the bottom housing 11. The controller 20 is mounted on the suspension frame 14, and the suspension frame 14 reliably positions the controller 20 in the cavity 111 of the bottom housing 11. More specifically, the suspension frame 14 includes a first frame 141 and a second frame 142. The screw 80 can be used to lock one end of the first frame 141 to the bottom wall of the bottom shell 11, and the extension direction of the first frame 141 is perpendicular to the extension direction of the bottom wall of the bottom shell 11. The second frame 142 can be welded to the other end of the first frame 141, or the screw 80 can be used to install the second frame 142 to the other end of the first frame 141. The controller 20 can be installed on the second frame 142 through the screw 80. In this way, the suspension frame 14 is used to suspend the controller 20 in the bottom shell cavity 111 of the bottom shell 11, which helps to save space in the cavity 111 of the bottom shell 11 and makes the structure of the detection device 1000 more compact.

[0038] Each of the batteries 30 is disposed in the cavity 111 of the bottom shell 11 to keep each of the batteries 30 in a watertight environment. For ease of description, one of the two batteries 30 is defined as a first battery 31 and the other battery 30 is defined as a second battery 32, wherein the first battery 31 and the second battery 32 are disposed side by side in the cavity 111 of the bottom shell 11. Specifically, the outer casing 10 includes a pressing plate 15, which is U-shaped, such that the pressing plate 15 has a pressing groove 151 and two side wings 152. The shape and width of the pressing groove 151 are consistent with the overall shape and width of the two batteries 30 arranged side by side. After the middle of the two side-by-side batteries 30 is received in the pressing groove 151 of the pressing plate 15, the screw 80 can be used to lock the two side wings 152 of the pressing plate 15 to the bottom wall of the bottom casing 11, so that the pressing plate 15 presses the two batteries 30 side by side against the bottom wall of the bottom casing 11, so that the two batteries 30 are reliably disposed in the cavity 111 of the bottom casing 11.

[0039] The pressure sensor 40 is installed in the mounting hole 114 of the bottom shell 11 to set the pressure sensor 40 in the bottom shell 11, and the pressure sensor 40 is connected to the controller 20. After the detection device 1000 is immersed in water, the pressure sensor 40 can detect the water pressure of the environment in which the detection device 1000 is located, and send the pressure data to the controller 20, so that the controller 20 can determine the water depth of the environment in which the detection device 1000 is located. Further, the bottom shell 11 has a retaining ring groove 115, which is located in the middle section of the mounting hole 114. The outer shell 10 includes a retaining ring 16, the outer side of which engages with the retaining ring groove 115 of the bottom shell 11, and the inner side of which presses against the end face of the pressure sensor 40 to reliably install the pressure sensor 40 in the mounting hole 114 of the bottom shell 11, preventing the pressure sensor 40 from moving relative to the bottom shell 11.

[0040] In the appendix Figures 1 to 12 In this specific example of the detection device 1000 of the present invention, the housing 10 includes a cap 17 having at least one cap body through-hole 171. The cap 17 is mounted in the mounting hole 114 of the bottom housing 11 to cover the pressure sensor 40, thereby concealing the pressure sensor 40 between the bottom housing 11 and the cap 17. Because the cap 17 has the cap body through-hole 171, the cap 17 does not affect the pressure sensor 40's detection of the water pressure in the environment where the detection device 1000 is located. Preferably, the shape and size of the cap 17 are consistent with the shape and size of the mounting hole 114 of the base shell 11. After the cap 17 is inserted into the mounting hole 114 of the base shell 11, the cap 17 is securely installed in the mounting hole 114 of the base shell 11 based on the friction between the outer wall of the cap 17 and the peripheral wall of the base shell 11 that defines the mounting hole 114. Optionally, in other examples of the detection device 1000 of this utility model, the cap 17 may be screwed into the mounting hole 114 of the base shell 11.

[0041] Preferably, the pressure sensor 40 has an annular groove 41, and the detection device 1000 includes a sealing ring 90, which may be made of rubber. The sealing ring 90 is fitted into the annular groove 41 of the pressure sensor 40. After the pressure sensor 40 is installed in the mounting hole 114 of the bottom shell 11, the sealing ring 90 is clamped between the pressure sensor 40 and the bottom shell 11, and the sealing ring 90 is slightly deformed so that the gasket 13 ensures the water tightness of the mounting position of the pressure sensor 40 and the bottom shell 11.

[0042] The electromagnet 50 includes an electromagnet body 51, a push rod 52, and a spring 53. The middle portion of the push rod 52 is drivably mounted on the electromagnet body 51. The spring 53 is fitted onto the bottom of the push rod 52, with one end of the spring 53 abutting against the electromagnet body 51 and the other end abutting against a retaining ring 521 at the bottom of the push rod 52. When the electromagnet body 51 is energized, it drives the push rod 52 upward. The retaining ring 521 of the push rod 52 compresses the spring 53 towards the bottom of the electromagnet body 51, causing the spring 53 to be compressed and deformed, retaining its elastic potential energy. When the electromagnet body 51 is de-energized, the spring 53 pushes the push rod 52 downward during its return to its initial state, thus resetting the push rod 52. In other words, the push rod 52 is telescopic.

[0043] It is worth mentioning that the electromagnet body 51 can be composed of a coil, an iron core, an armature, and other necessary structures. The connection relationship between the electromagnet body 51, the push rod 52, and the spring 53 is consistent with the electromagnet disclosed in the utility model patent with authorization announcement number CN216923383U. This will not be described again in the detection device 1000 of this utility model.

[0044] The electromagnet body 51 is mounted on the bottom wall of the bottom shell 11, and the electromagnet body 51 is connected to the first battery 31 and the controller 20, so that the electromagnet body 51 is located in the cavity 111 of the bottom shell 11 and the controller 20 controls the first battery 31 to supply power to the electromagnet 50. The pressing end 522 of the push rod 52 extends through the rod hole 112 of the bottom shell 11 to the outside of the bottom shell 11. (See attached...) Figures 1 to 12 In this specific example of the detection device 1000 of the present invention shown, after the middle part of the electromagnet body 51 is received in the pressure plate groove 151 of the pressure plate 15, the screw 80 is used to lock the electromagnet body 51 to the pressure plate 15 and to lock the two side wings 152 of the pressure plate 15 to the bottom wall of the bottom shell 11, thereby installing the electromagnet body 51 on the bottom wall of the bottom shell 11 so that the electromagnet body 51 is reliably disposed in the cavity 111 of the bottom shell 11.

[0045] Furthermore, a sealing ring 90 is fitted onto the top of the push rod 52, and the sealing ring 90 is clamped between the bottom shell 11 and the push rod 52. The sealing ring 90 ensures the watertightness of the joint between the push rod 52 and the bottom shell 11, while allowing the push rod 52 to extend and retract. Preferably, a retaining ring groove 115 is provided in the middle section of the rod hole 112 of the bottom shell 11. The outer side of a retaining ring 16 is engaged in the retaining ring groove 115 of the bottom shell 11, and the inner side of the retaining ring 16 presses against the sealing ring 80. In this way, the retaining ring 16 can prevent the sealing ring 90 from moving relative to the bottom shell 11, thereby ensuring the watertightness of the joint between the bottom shell 11 and the push rod 52.

[0046] Furthermore, the push rod 52 includes a push rod body 523 and a pressing cap 524. The middle portion of the push rod body 523 is drivably mounted to the electromagnet body 51. The top of the push rod body 523 extends to the outside through the rod hole 112 of the bottom shell 11. The pressing cap 524 is mounted on the top of the push rod body 523 to form the pressing end 522. (See attached...) Figures 1 to 12 In this specific example of the detection device 1000 of the present invention shown, the pressing cap 524 may be, but is not limited to, made of rubber, to increase the area of ​​the component used for pressing the button 2001 of the microphone 2000, ensuring effective pressing while protecting the button 2001 of the microphone 2000, which is made of plastic. It is worth noting that the specific manner in which the pressing cap 524 is installed on the top of the push rod body 523 is not limited in the detection device 1000 of the present invention. For example, the pressing cap 524 may have a cap hole 5241, into which the top of the push rod body 523 is inserted. Based on the friction between the top of the push rod body 523 and the inner wall of the pressing cap 524, the pressing cap 524 is securely installed on the top of the push rod body 523. Optionally, in other examples of the detection device 1000 of this utility model, the top of the push rod body 523 has an external thread, the cap hole 5241 of the pressing cap 524 is a threaded hole, and the top of the push rod body 523 is screwed into the cap hole 5241 of the pressing cap 524, so that the pressing cap 524 is firmly installed on the top of the push rod body 523.

[0047] The watertight terminal 60 is installed in the first terminal hole 113 of the bottom shell 11, and the watertight terminal 60 is connected to the second battery 32 and one end of the three-way watertight cable 4000, so that the second battery 32 can supply power to the underwater communication device 3000 through the three-way cable 4000.

[0048] The bracket 70 is mounted on the base housing 11. For example, a set of screws 80 can be used to mount the bracket 70 to the base housing 11. The bracket 70 is adjacent to the pressing end 522 of the push rod 52 of the electromagnet 50. The bracket 70 is used to mount the receiver 2000.

[0049] Further, the bracket 70 includes a first extension portion 71 and a second extension portion 72 extending from one end of the first extension portion 71 in a direction perpendicular to the first extension portion 71. The end of the first extension portion 71 facing away from the second extension portion 72 is mounted on the bottom shell 11. The second extension portion 72 extends above the pressing end 522 of the push rod 52 of the electromagnet 50, and the second extension portion 72 has at least one locking groove 721. The locking groove 721 is positioned directly opposite the pressing end 522 of the push rod 52 of the electromagnet 50. The microphone 2000 is locked into the locking groove 721 of the second extension portion 72. The bracket 70 suspends the button 2001 of the microphone 2000 directly above the pressing end 522 of the push rod 52 of the electromagnet 50, and the button 2001 is adjacent to the pressing cap 54.

[0050] Furthermore, the bottom shell 11 has a second terminal hole 116, which communicates with the shell cavity 111. The detection device 1000 further includes a charging communication terminal 100, which is watertightly installed in the second terminal hole 116 of the bottom shell 11. The first battery 31 and the second battery 32 are respectively connected to the charging communication terminal 100, wherein external power can be supplied to the first battery 31 and the second battery 32 through the charging communication terminal 100.

[0051] In the appendix Figures 1 to 12In this specific example of the detection device 1000 of the present invention, the bottom shell 11 has a plurality of rod holes 112 and a plurality of first terminal holes 113. The rod holes 112 are spaced apart on one side of the bottom shell 11, and the first terminal holes 113 are spaced apart on the other side of the bottom shell 11. There are multiple electromagnets 50, and the pressing end 522 of the push rod 52 of each electromagnet 50 extends to the outside through the respective rod holes 112 of the bottom shell 11. There are multiple watertight terminals 60, and each watertight terminal 60 is installed in the respective first terminal holes 113 of the bottom shell 11. In this manner, the detection device 1000 can test multiple underwater communication devices 3000 at a time, thereby improving testing efficiency. The suspension bracket 14 is used to suspend the controller 20 outside the electromagnet body 51 of the electromagnet 50.

[0052] More specifically, the bottom shell 11 has four rod holes 112 and four first terminal holes 113. The four rod holes 112 are spaced apart on one side of the bottom shell 11, and the four first terminal holes 113 are spaced apart on the other side of the bottom shell 11. There are four electromagnets 50, and the electromagnet bodies 51 of the four electromagnets 50 are spaced apart and mounted on the bottom wall of the bottom shell 11.

There are four watertight terminals 60, and each watertight terminal 60 is watertightly mounted in the respective first terminal holes 113 of the bottom shell 11. It can be understood that the second extension portion 72 of the bracket 70 has four mounting slots 721, and each mounting slot 721 corresponds one-to-one with the pressing end 522 of the push rod 52 of each electromagnet 50. With the above-described structure, the detection device 1000 can test four underwater communication devices 3000 at a time, thereby improving testing efficiency.

The three ends of the three-way watertight cable 4000 are respectively connected to the watertight terminal 60, the transceiver 2000, and the underwater communication device 3000. It is understood that the main control device (e.g., a surface computer) can be connected to the charging communication terminal 100 of the detection device 100 via a watertight cable. When the assembly consisting of the detection device 1000, the transceiver 2000, the underwater communication device 3000, and the three-way watertight cable 4000 is placed underwater, the pressure sensor 40 can detect the water pressure of the environment and send the water pressure data to the controller 20. The controller 20 can then determine the water depth of the environment where the detection device 1000 is located. When the assembly sinks to a preset depth (e.g., 60m), the controller 20 controls the first battery 31 to supply power to the electromagnet body 51, so that the electromagnet body 51 drives the push rod 52's pressing cap 524 to move quickly toward the button 2001 of the transceiver 2000 and press the button 2001, and then quickly releases it to simulate a hand pressing action. At this time, the second battery 32 is allowed to supply power to the underwater communication device 3000 and automatically start the underwater communication device 3000, thereby testing the underwater communication device 3000.
