Description

Technical Field

[0001] The utility model relates to the field of underwater operation equipment, in particular to an underwater environment testing device. Background Art

[0002] Currently, underwater environment testing is primarily performed using underwater robots (AUVs). These robots utilize a robot body and control system to perform underwater light field, depth, and imaging tests. The AUV's control system is typically installed on the nearest vessel. However, due to the influence of ocean currents, wind, and waves, the vessel's precise positioning cannot be accurately determined. Consequently, the AUV cannot maintain relative coordinates with the vessel, resulting in positioning errors in the AUV's test data, which in turn affects the evaluation of the underwater environment. Utility Model Content

[0003] In order to address the defects of the prior art, the utility model provides an underwater environment testing device to ensure that the spectrometer can accurately obtain underwater light field data at a specific depth below the installation base, thereby reducing the positioning error of the test data and improving the accuracy of the underwater environment evaluation through the test data.

[0011] Wherein, the connecting rope assembly includes:

[0012] The wire wheel is rotatably mounted on the mounting base and is provided with a first bracket.

[0013] A pull rope, wherein a first end of the pull rope is wound around the pulley, and a second end of the pull rope is fixed to the carrying plate.

[0014] Wherein, the connecting rope assembly further includes:

[0015] A connecting ring, one end of which is connected to the second end of the pull rope, and the second end of the connecting ring is installed on the mounting plate.

[0016] Wherein, the connecting rope assembly further includes:

[0017] Multiple sleeves are connected end to end in sequence, and the inner diameters of the multiple sleeves increase from top to bottom. The sleeves close to the mounting base are connected to the mounting base, and the sleeves close to the mounting plate are connected to the mounting plate. The multiple sleeves are sleeved on the pull rope.

[0025] The implementation of this utility model has the following beneficial effects:

[0026] The underwater environment testing device provided in this embodiment can be mounted on a carrying object, including but not limited to a vessel. A connecting rope assembly connects the mounting base to a carrying plate. A counterweight is then used to pull the carrying plate downward, thereby lowering the depth sounder and spectrometer to a specific depth underwater. The spectrometer can then be used to obtain underwater light field data at that specific depth.

[0027] Since the depth sounder and spectrometer are connected to the mounting base through a connecting rope assembly, the depth sounder and spectrometer can move synchronously with the mounting base on the carried object to achieve relative positioning between the spectrometer, depth sounder and the carried object, ensuring that the spectrometer can accurately obtain underwater light field data at a specific depth under the mounting base, thereby reducing the positioning error of the test data and improving the accuracy of the underwater environment assessment through test data. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a structural schematic diagram of the underwater environment testing device of the present utility model. DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0030] The underwater environment testing device provided by the present invention ensures that the spectrometer 4 can accurately obtain underwater light field data at a specific depth below the mounting base 1, thereby reducing the positioning error of the test data and improving the accuracy of underwater environment evaluation through the test data.

[0031] In one embodiment of the present invention, Figure 1 As shown, the underwater environment testing device includes a mounting base 1, a connecting rope assembly, a depth sounder 3, a spectrometer 4, and a counterweight 5. The first end of the connecting rope assembly is connected to the mounting base 1, and the second end of the connecting rope assembly is provided with a carrying plate 21. The length of the connecting rope assembly is adjustable. The depth sounder 3 and the spectrometer 4 are both mounted on the carrying plate 21. The depth sounder 3 is used to measure the sinking depth of the carrying plate 21, and the spectrometer 4 is used to measure the underwater light field data at the depth of the carrying plate 21. The counterweight 5 is provided on the carrying plate 21 and is used to drive the carrying plate 21 to sink, so that the depth sounder 3 and the spectrometer 4 sink synchronously.

[0032] According to the underwater environment testing device provided in this embodiment, the mounting base 1 can be installed on a carrying object, including but not limited to a vessel. A connecting rope assembly connects the mounting base 1 to a carrying plate 21. A counterweight 5 then pulls the carrying plate 21 downward, lowering the depth sounder 3 and spectrometer 4 to a specific depth underwater. Spectrometer 4 then acquires underwater light field data at that specific depth.

[0033] Since the depth sounder 3 and the spectrometer 4 are connected to the mounting base 1 through the connecting rope assembly, the depth sounder 3 and the spectrometer 4 can move synchronously with the mounting base 1 on the carried object to achieve relative positioning between the spectrometer 4, the depth sounder 3 and the carried object, thereby ensuring that the spectrometer 4 can accurately obtain underwater light field data at a specific depth under the mounting base 1, thereby reducing the positioning error of the test data and improving the accuracy of evaluating the underwater environment through the test data.

[0034] In addition, the underwater environment testing device can collect underwater environment data by simply connecting the depth sounder 3 and the spectrometer 4 to the mounting base 1 through the mounting plate 21 and the connecting rope assembly. The overall structure is simple, which makes it easy to carry the underwater environment testing device for movement and installation.

[0035] In the embodiment of the present utility model, as Figure 1 As shown, the counterweight 5 is a gravity hammer, which includes a main hammer 51 and a sub-hammer 52 . The main hammer 51 is arranged on the lower side of the carrying plate 21 , and the sub-hammer 52 is detachably connected to the main hammer 51 .

[0036] It is understood that when it is necessary to use the depth sounder 3 and spectrometer 4 to test underwater environmental data, the gravity hammer's own weight can be used to drive the carrier plate 21 to sink, thereby driving the depth sounder 3 and spectrometer 4 to a certain depth underwater. During this process, the actual sinking depth of the depth sounder 3 and spectrometer 4 corresponds to the gravity hammer's own weight. Since the gravity hammer's sub-hammer 52 and mother hammer 51 are detachably connected, the weight of the sub-hammer 52 can be changed before the gravity hammer sinks, according to the actual sinking depth requirements, thereby changing the overall weight of the gravity hammer and achieving the desired sinking depth of the depth sounder 3 and spectrometer 4. Furthermore, the sub-hammer 52 of the gravity hammer can be adjusted according to different test water depth requirements to meet the actual required test conditions.

[0037] In addition, the weight of the sub-hammer 52 can also be adjusted according to the size of wind waves and ocean currents of different sizes, so as to further ensure that the carrying plate 21 can move with the mounting base 1, ensure that the depth sounder 3 and the spectrometer 4 maintain a relative position with the mounting base 1, and reduce the impact of wind waves and ocean currents on the positions of the depth sounder 3 and the spectrometer 4.

[0038] In the embodiment of the present utility model, as Figure 1As shown, the connecting rope assembly includes a reel 22 and a pull rope 23. The mounting base 1 is provided with a first bracket 13, and the reel 22 is rotatably mounted on the first bracket 13. The first end of the pull rope 23 is wound around the reel 22, and the second end of the pull rope 23 is fixed to the mounting plate 21. When the counterweight 5 pulls the mounting plate 21 downward, the mounting plate 21 pulls the pull rope 23, pulling the pull rope 23 out of the reel 22, allowing the pull rope 23 to lengthen as the counterweight 5 sinks. The pull rope 23 thus ensures the connection between the mounting plate 21 and the mounting base 1, ensuring that the mounting plate 21 can move with the mounting base 1 via the pull rope 23. This ensures that the depth sounder 3 and the spectrometer 4 can maintain their relative positions with the mounting base 1, thereby reducing test data errors.

[0039] Furthermore, a reel crank 221 is rotatably mounted on the first bracket 13. The reel crank 221 is connected to the reel 22. When the counterweight 5 pulls the pull rope 23 downward, the reel crank 221 can be rotated to release the pull rope 23 from the reel 22, thereby accelerating the sinking rate of the counterweight 5. When the depth sounder 3 and the spectrometer 4 need to be retrieved from underwater, the reel crank 22 can be driven by the reel crank 221 to rotate and retract the pull rope 23 into the reel 22, thereby retrieving the depth sounder 3 and the spectrometer 4 from underwater. The reel crank 221 can improve the convenience of operating the pull rope 23.

[0040] Furthermore, if Figure 1 As shown, the connecting rope assembly further includes a connecting ring 24. One end of the connecting ring 24 is connected to the second end of the pull rope 23, and the second end of the connecting ring 24 is mounted on the carrying plate 21. The overall structure of the connecting ring 24 increases the contact area between the pull rope 23 and the carrying plate 21, thereby strengthening the connection between the pull rope 23 and the carrying plate 21. When the gravity of the counterweight 5 acts on the carrying plate 21, the carrying plate 21 can distribute the force to the overall structure of the connecting ring 24 and the pull rope 23, thereby avoiding the generation of a single-point force between the carrying plate 21 and the pull rope 23, effectively reducing the risk of the pull rope 23 being broken, and improving the connection stability between the pull rope 23 and the carrying plate 21, the depth sounder 3, and the spectrometer 4, further ensuring that the depth sounder 3 and the spectrometer 4 can maintain their relative position with the mounting base 1.

[0041] Preferably, in this embodiment, the connecting ring 24 is an 8-shaped ring.

[0042] On the other hand, to extend the service life of the pull rope 23, measures can be taken to protect the pull rope 23. Specifically, the connecting rope assembly also includes multiple sleeves, which are connected end to end. The inner diameters of the sleeves increase from top to bottom. The sleeve near the mounting base 1 is connected to the mounting base 1, and the sleeve near the mounting plate 21 is connected to the mounting plate 21. The multiple sleeves are sleeved around the pull rope 23.

[0043] It is understandable that, because the multiple sleeves are connected end to end in sequence, and the inner diameters of the multiple sleeves increase from top to bottom, a telescopic tube structure is formed between the multiple sleeves. When the underwater environment testing device is not in use, the multiple sleeves are stacked in sequence and sleeved on the outer surface of the extended pull rope 23. When the counterweight 5 pulls the carrying plate 21 to sink, and the pull rope 23 is stretched, the stacked sleeves are extended in sequence, so that the sleeves form a protection for the outer surface of the pull rope 23, preventing fish from biting the pull rope 23, and preventing the pull rope 23 from breaking and causing the depth sounder 3, spectrometer 4 to be disconnected from the mounting base 1. The protection of the multiple sleeves improves the stability of the connection between the depth sounder 3, spectrometer 4 and the mounting base 1.

[0044] In the embodiment of the present utility model, as Figure 1 As shown, the mounting base 1 includes a base 11 and a beam 12, the first end of the beam 12 is connected to the base 11, the carrying plate 21 is located below the second end of the beam 12, and the base 11 is suitable for connecting to a carried object to install the beam 12 on the carried object.

[0045] The crossbeam 12 and the base 11 are integrally formed, and the base 11 is mounted on the carried object via bolts to ensure the stability of the crossbeam 12 and the base 11. When performing underwater environmental testing using the underwater environmental testing device, the base 11 and crossbeam 12 are mounted on the carried object. After the depth sounder 3, the spectrometer 4, and the counterweight 5 are mounted on the carrying plate 21, and the carrying plate 21 is connected to the bottom of the second end of the crossbeam 12 via a connecting rope assembly, the second end of the crossbeam 12 is extended from the carried object to the water surface, so that the counterweight 5 can drive the sounder and spectrometer 4 to sink to a certain depth, thereby conducting underwater environmental testing.

[0046] Furthermore, a second bracket 14 is provided at the second end of the crossbeam 12. The second bracket 14 is rotatably connected to a guide wheel 15. The second end of the pull rope 23 passes around the guide wheel 15 and is connected to the carrying plate 21. The first end of the pull rope 23 can then be fixed inside the carried object. The release and retraction of the pull rope 23 can be completed from within the carried object without requiring operation outside the carried object, effectively improving safety during the release and retraction of the pull rope 23.

[0047] In this embodiment of the present invention, a camera 6 and a lighting fixture are also included. Both the camera 6 and the lighting fixture are mounted on the mounting plate 21. The camera 6 is used to capture images of the underwater environment at the depth of the mounting plate 21. This allows the user to determine the movements and concentration of fish schools at the depth of the mounting plate 21, thereby providing data support for underwater fishing and other aspects. The lighting fixture can enhance the brightness of the captured underwater images, facilitating accurate assessment of the movements and concentration of fish schools in the images.

[0048] In addition, since different types of fish have different phototropism, different light colors can attract different fish species. In this embodiment, the lighting lamps can use different models of LED fish-attracting lamps. The degree of fish aggregation in the underwater environment image can verify the fish-attracting performance of the corresponding LED fish-attracting lamps to a certain extent.

[0049] In an embodiment of the present invention, one of the depth sounder 3 and the spectrometer 4 is equipped with a temperature measuring element, which is used to obtain the underwater environmental temperature at the depth of the mounting plate 21, thereby obtaining the adaptation temperature of the fish school at the corresponding depth, so as to understand the living habits of the fish school at the corresponding depth and provide data basis for fields such as marine ranches at the corresponding depth.

[0050] In this embodiment, the temperature measuring element may be a sea surface thermometer.

[0051] In an embodiment of the present utility model, the outer surface of the depth sounder 3 and the outer surface of the spectrometer 4 are coated with an anti-corrosion coating, so that the outer surface of the depth sounder 3 and the outer surface of the spectrometer 4 are protected by the anti-corrosion coating, thereby reducing the corrosion of the outer surface of the depth sounder 3 and the outer surface of the spectrometer 4 by seawater.

[0052] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
