Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine aquaculture engineering, and in particular to a monitoring device arranged in an aquaculture net cage. BACKGROUND

[0002] In recent years, deep-sea aquaculture net cage technology for marine fish has developed rapidly. It utilizes the vast space and natural conditions of the ocean to breed fish, not only reducing dependence on land resources, but also providing a more natural growing space for fish, which helps to improve the health and meat quality of fish. In addition, deep-sea aquaculture net cages can effectively avoid the negative effects of near-shore pollution, reduce the incidence of disease, and because of more sufficient water exchange, the water quality is usually better, which provides a good living environment for fish. Therefore, this breeding method not only improves yield but also guarantees product quality.

[0003] In order to ensure the healthy growth of fish in deep-sea aquaculture net cages, operators need to regularly use monitoring instruments to detect water quality parameters (such as dissolved oxygen, temperature, salinity, etc.) in the enclosed area of the aquaculture net cage, current conditions, and observe the situation in the breeding area by recording videos. These data are crucial for timely detection of abnormal conditions that may affect fish health, such as water eutrophication or invasion of harmful organisms. Based on this monitoring information, operators can flexibly adjust the position and layout of the aquaculture net cage to optimize the breeding environment to adapt to different environmental changes and ensure the smooth progress of breeding activities.

[0004] However, the existing method has obvious shortcomings. Because the deep-sea aquaculture net cage covers a wide area, it is difficult to manually determine the optimal position for placing monitoring instruments, and positioning errors are likely to occur, resulting in inaccurate acquisition of the true situation of the breeding area. Such deviations will directly affect the reliability and accuracy of the monitoring data, and thus affect the effectiveness of decision-making. Therefore, how to accurately deploy monitoring equipment to the ideal position and reduce the problem of inaccurate monitoring caused by position errors has become a key challenge that needs to be addressed. This is not only an important link to improve monitoring efficiency and aquaculture management level, but also a necessary condition for promoting the development of deep-sea aquaculture technology in a more scientific and intelligent direction.

[0007] In an embodiment, the bearing support comprises: a first frame body, the floating component being sleeved on the first frame body; a second frame body, connected to the first frame body, a plurality of lifting rings being arranged on the second frame body, the number of the lifting rings being the same as that of the pull components, each lifting ring being connected to the top of the breeding net cage through a corresponding pull component, and the circumferential dimension of the second frame body being greater than that of the first frame body, the floating component being supported on the second frame body by buoyancy; and a third frame body, connected to the side of the first frame body away from the second frame body, the monitoring assembly being installed in the third frame body.

[0009] In an embodiment, the number of the pull components is four; the second frame body comprises: two connecting rods, the rod bodies of the two connecting rods being arranged in a cross manner and connected to the first frame body, and the lifting rings being arranged on the two end portions of the two connecting rods extending outward, and the four lifting rings being connected to the breeding net cage through the corresponding pull components.

[0010] In an embodiment, the pull component is a steel wire rope, and the steel wire rope is made of stainless steel.

[0011] In an embodiment, further comprising: a counterweight component, arranged on the third frame body; the density of the counterweight component being greater than the density of water, so as to exert a second action force on the bearing support, the output direction of the second action force being the water bottom direction of the breeding area.

[0012] In an embodiment, the monitoring assembly comprises: a first monitoring component mounted on the third frame body for collecting sea current data of the culture area; a second monitoring component mounted on the third frame body for collecting water quality data of the culture area, the second monitoring component being located on one side of the first monitoring component; and a third monitoring component mounted on the third frame body for monitoring the fish population in the culture area through visual function, the third monitoring component being located above the second monitoring component.

[0013] In an embodiment, the monitoring assembly further comprises: a communication assembly arranged on the culture cage for sending the environmental parameters and image data obtained by the monitoring assembly; a water-tight communication cable for electrically connecting the communication assembly and the monitoring assembly; and a weight steel wire arranged on the outer surface of the water-tight communication cable in a bundled and wound manner for increasing the weight of the water-tight communication cable.

[0014] In an embodiment, the communication assembly comprises: three communication components, the first monitoring component, the second monitoring component, and the third monitoring component being connected to the corresponding communication components through the water-tight communication cable, so that the three communication components can respectively send the water quality data, the image data, and the sea current data of the culture area.

Through improving the culture efficiency and product quality, the present application has important significance for promoting the development of the entire industry.

[0032] In the following, only certain example embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature and not limiting.

[0033] Reference Figures 1 to 3As shown, the monitoring device in the aquaculture net cage in the embodiment of the application can include: a bearing support 1 for placing in the aquaculture area enclosed by the aquaculture net cage 6; a float component 2 installed on the bearing support 1, the density of the float component 2 being less than the density of water, so as to exert a first action force on the bearing support 1, the output direction of the first action force being the water surface direction of the aquaculture area; at least three tie components 3, the bearing support 1 being connected with the aquaculture net cage 6 through each tie component 3, each tie component 3 being arranged in a circumferential direction of the bearing support 1, a pulling action force being formed on the bearing support 1 through each tie component 3, so as to limit the bearing support 1 at a target position in the aquaculture area; and a monitoring assembly 4 arranged on the bearing support 1, for monitoring the underwater environment of the aquaculture area in real time.

[0034] Specifically, in the technical scheme adopted in the present application, when the bearing support 1 is connected with the aquaculture net cage 6 through the tie components 3, the length of the tie components 3 can be limited, and the position of the bearing support 1 in the aquaculture area is positioned by the pulling action force exerted by the tie components 3, i.e. the above-mentioned target position, specifically the monitoring position of the monitoring device in the aquaculture net cage 6, for example, based on the central position of the aquaculture area in the sea level direction, the opposite tie components 3 can be set to be equal in length, or the length of the tie components 3 is determined with reference to the radius of the aquaculture area, so as to position the bearing support 1 at the middle part of the aquaculture area. Since the density of the float component 2 is less than the density of water, when the float component 2 is immersed in water, the weight of the displaced water is greater than the weight of the float component 2 itself, i.e. the buoyancy is greater than the gravity, and the float component 2 will be subjected to upward buoyancy and float on the water surface, wherein the upward buoyancy is the first action force; in the present application, the float component 2 can be a life buoy. The monitoring assembly 4 can be arranged at the target position in the aquaculture area through the bearing support 1, since the bearing support 1 will increase its own weight after the monitoring assembly 4 is arranged, so as to enable the bearing support 1 to generate a sinking action force towards the bottom of the aquaculture area, and when the sinking action force interacts with the first action force, the bearing support 1 is vertically arranged at the target position, so that the monitoring assembly 4 can monitor the underwater environment in the aquaculture area. The purpose of monitoring the underwater environment of the aquaculture area is achieved, which effectively ensures that the underwater environment can be found in time when an abnormal situation occurs, and the underwater environment of the aquaculture area can be adjusted in time, so as to avoid slow growth or mass death of fish due to abnormal environment.

[0035] Further, with reference to Figure 3As shown, in some embodiments, the bearing support 1 comprises: a first frame body 11, the float component 2 is sleeved on the first frame body 11; a second frame body 12 connected to the first frame body 11, the second frame body 12 is provided with a number of lifting rings 122 which is same as the number of each tie component 3, each lifting ring 122 is connected to the top of the culture net cage 6 through the corresponding tie component 3, and the circumferential dimension of the second frame body 12 is greater than the circumferential dimension of the first frame body 11, the float component 2 is supported on the second frame body 12 by the buoyancy; a third frame body 13 connected to the side of the first frame body 11 away from the second frame body 12, the monitoring assembly 4 is installed in the third frame body 13.

[0036] Specifically, in the technical scheme adopted in the present application, the first frame body 11 can be provided as a cuboid structure, so as to facilitate the float component 2 to be sleeved on the first frame body 11, the first frame body 11 can be erected in water by the first action force exerted by the float component 2, the second frame body 12 can be connected to the top of the first frame body 11 in the erected state, and the third frame body 13 can be connected to the bottom of the first frame body 11 in the erected state. At least three lifting rings 122 are provided on the second frame body, each lifting ring 122 is connected to the culture net cage 6 through the corresponding tie component 3, and the included angle between adjacent tie components 3 is set to be the same angle when the target position is the center of the circle. Taking three lifting rings 122 and three tie components 3 as an example, the included angle between adjacent tie components 3 is set to be 120 degrees when the target position is the center of the circle; if four lifting rings 122 and four tie components 3 are taken as an example, the included angle between adjacent tie components 3 is 90 degrees when the target position is the center of the circle, so as to stably exert the pulling action force on the second frame body 12.

[0037] Further, referring to Figure 3 As shown, in some embodiments, the number of tie components 3 is three;

[0038] The second frame body 12 comprises: three connecting rods 121, the rod bodies of the three connecting rods 121 are connected to the first frame body 11, and one end of the three connecting rods 121 is arranged oppositely, the lifting rings 122 are arranged at the other end of the three connecting rods 121 extending outward, and the three lifting rings 122 are connected to the culture net cage 6 through the corresponding tie components 3.

[0039] Specifically, in an embodiment of the technical scheme adopted in the present application, the number of the pulling components 3 can be set to three, and the number of the lifting rings 122 on the second frame body 12 is also three. In the embodiment, the second frame body 12 can be composed of three connecting rods 121, the rod bodies of the three connecting rods 121 are connected with one side of the first frame body 11, and the one ends of the connecting rods 121 are oppositely arranged, and the other ends extend outward, which can extend along three directions of the sea level, and the directions of the outward extension of the connecting rods 121 are uniformly arranged, and when the target position is taken as the center, the included angle between the outer ends of the adjacent connecting rods 121 is 120 degrees, and the lifting rings 122 are arranged at the outer end portions of the connecting rods 121, so that when the lifting rings 122 are connected with the net cages 6 through the pulling components 3, balanced pulling forces can be formed on the bearing bracket 1, so as to realize the limitation of the bearing bracket 1 at the target position.

[0040] Further, referring to Figure 3 , in some embodiments, the number of the pulling components 3 is set to four;

[0041] The second frame body 12 includes two connecting rods 121, the rod bodies of the two connecting rods 121 are cross-arranged and connected with the first frame body 11, and the lifting rings 122 are arranged at the two end portions of the two connecting rods 121, and the four lifting rings 122 are connected with the net cages 6 through the corresponding pulling components 3.

[0042] Specifically, in the technical scheme adopted in the present application, the number of the pulling components 3 can be set to four, and the number of the lifting rings 122 on the second frame body 12 is also four. In the embodiment, the second frame body 12 can be composed of two connecting rods 121, the rod bodies of the two connecting rods 121 are connected with one side of the first frame body 11, and the two connecting rods 121 are vertically cross-arranged, so that the four end portions of the two connecting rods 121 extend outward, which can extend along four directions of the sea level, and since the two connecting rods 121 are vertically cross-arranged, when the target position is taken as the center, the included angle between the adjacent outer end portions of the two connecting rods 121 is 90 degrees, and the lifting rings 122 are arranged at the outer end portions of the connecting rods 121, so that when the lifting rings 122 are connected with the net cages 6 through the pulling components 3, balanced pulling forces can be formed on the bearing bracket 1, so as to realize the limitation of the bearing bracket 1 at the target position.

[0043] It should be noted that in the embodiments of the present application, more numbers of the pulling components 3 and the lifting rings 122 can also be adopted, and when the lifting rings 122 are connected with the net cages 6 through the corresponding pulling components 3, the pulling forces applied on the bearing bracket 1 can limit the bearing bracket 1 at the target position, which are all within the protection scope of the present application.

[0044] Further, referring to Figure 1 andFigure 2 As shown in some embodiments, the pulling component 3 is a steel wire rope, which is made of stainless steel.

[0045] Specifically, in one embodiment of the technical scheme adopted in the present application, the pulling component 3 can be a steel wire rope, so as to connect the load-bearing bracket 1 to the culture net cage 6 through the lifting ring 122. Since part of the structure of the pulling component 3 needs to intrude into the water, the steel wire rope in this embodiment can be made of stainless steel to prolong the service life of the pulling component 3. In some embodiments, a winch can be installed on the culture net cage 6, and the pulling component 3 is wound and arranged on the winch, so that the length of part of the pulling component 3 between the culture net cage 6 and the load-bearing bracket 1 can be adjusted by the winch to achieve the purpose of adjusting the target position. Thus, the load-bearing bracket 1 can be adjusted to the center position of the breeding area according to the size of the breeding area enclosed by the culture net cage 6, or a part of the breeding area needs to be monitored, and the length of the pulling component 3 can be adjusted at any time by the winch to limit the load-bearing bracket 1 to the center position of the monitored area. This effectively improves the practicality and versatility of the monitoring device, making the monitoring means of the monitoring device more targeted and adaptable to various abnormal situations in the water.

[0046] Further, referring to Figure 3 As shown in some embodiments, the counterweight component 5 is arranged on the third frame body 13, and the density of the counterweight component 5 is greater than the density of water, so as to exert a second force on the load-bearing bracket 1, and the output direction of the second force is the direction of the bottom of the breeding area.

[0047] Specifically, in the technical scheme adopted in the present application, the weight of the load-bearing bracket 1 and the first force cannot promote the load-bearing bracket 1 to be in a balanced state at the target position in some cases. The counterweight component 5 can be arranged on the third frame body 13. Since the density of the counterweight component 5 is greater than the density of water, the counterweight component 5 can break through the buoyancy in the water and sink to the bottom of the breeding area, thereby exerting a second force on the load-bearing bracket 1 in the opposite direction of the first force, so that the second force and the first force interact on the load-bearing bracket 1 to achieve the balanced state of the load-bearing bracket 1. In order to realize that the second force is perpendicular to the bottom of the breeding area based on the load-bearing bracket 1, the counterweight component 5 can be arranged at the center position of the bottom of the third frame body 13, or arranged on the frame of the third frame body 13, so as to avoid the situation that the third frame body 13 is affected by the second force and deviates.

[0048] Further, referring to Figure 3As shown, in some embodiments, the monitoring assembly 4 comprises: a first monitoring component 41 mounted on the third frame body 13 for collecting sea current data of the breeding area; a second monitoring component 42 mounted on the third frame body 13 for collecting water quality data of the breeding area, the second monitoring component 42 being located on one side of the first monitoring component 41; and a third monitoring component 43 mounted on the third frame body 13 for monitoring the fish population of the breeding area through visual function, the third monitoring component 43 being located above the second monitoring component 42.

[0049] Specifically, in the technical scheme adopted in the present application, the first monitoring component 41 can be a sea current meter mounted on the third frame body 13, so as to collect sea current data in the breeding area with the target position as the center; the second monitoring component 42 is a water quality detector mounted on the third frame body 13, so as to monitor the water quality of the seawater flowing through the target position; and the third monitoring component 43 can be a super-wide-angle camera for shooting the underwater situation of the breeding area.

[0050] In the embodiments of the present application, the first monitoring component 41 is specifically a high-precision acoustic sea current profiler, which has a plurality of acoustic transducers and can emit sound waves in different directions and receive reflected waves, so as to accurately calculate the sea current velocity and direction by measuring the change of the sound wave frequency. The first monitoring component 41 can monitor the sea current situation at different depths and directions in real time, and collect the sea current data of the breeding area at a frequency of several times per second. The second monitoring component 42 can include a water quality sensor capable of quickly sensing the dissolved oxygen content in water, a temperature sensor for accurately measuring water temperature by using the characteristics of a thermistor, and a pH value sensor for real-time feedback of water body pH value based on electrochemical principle. The second monitoring component 42 collects water quality data every few minutes. The third monitoring component 43 uses an underwater high-definition camera combined with image recognition technology to monitor the size of fish, captures fish images from multiple angles, and transmits image data to a data processing center. After that, the average size and size distribution range of fish are estimated by using a pre-trained deep learning model to identify the outline and size of fish. When the light intensity sensor on the camera senses the light intensity, it can cooperate with the temperature sensor to comprehensively monitor the change of water temperature. Through the visual function of the third monitoring component 43, the feed amount and time can also be observed, and the fish growth environment can be comprehensively judged.

[0051] Further, in some embodiments, the monitoring assembly 4 further comprises: a communication assembly arranged on the net cage 6 for sending the underwater environmental parameters and image data acquired by the monitoring assembly 4; a water-tight communication cable electrically connected between the communication assembly and the monitoring assembly 4; and a weight steel wire arranged on the outer surface of the water-tight communication cable in a bundled and wound manner, for increasing the weight of the water-tight communication cable.

[0052] Specifically, in some embodiments of the technical solutions adopted in the present application, the aquaculture net cage 6 is also provided with a communication assembly for sending monitoring data. The communication assembly can be electrically connected with the monitoring assembly 4 through a watertight communication cable, so that the communication assembly can obtain the monitoring data measured by the monitoring assembly 4, and convert and send the monitoring data, thereby achieving the purpose of real-time monitoring of the aquaculture area. In the embodiments of the present application, the watertight communication cable is provided with a counterweight steel wire on the outer peripheral surface. The counterweight steel wire is fixed on the outer surface of the watertight communication cable in the form of bundled winding, thereby increasing the total weight of the watertight communication cable, resisting the impact of part of the sea current, reducing the shaking amplitude of the watertight communication cable in seawater, reducing the pulling force of seawater on the connection end of the watertight communication cable, thereby prolonging the service life of the watertight communication cable.

[0053] Further, in some embodiments, the communication assembly includes three communication components, the first monitoring component 41, the second monitoring component 42 and the third monitoring component 43 are respectively connected with the corresponding communication components through the watertight communication cable, so that the three communication components respectively send the water quality data, the image data and the sea current data of the aquaculture area.

[0054] Further, referring to Figure 1 In some embodiments, the communication component includes a waterproof box body mounted on the aquaculture net cage 6, the waterproof box body has a sealed containing space inside; a communication chip is arranged inside the waterproof box body for processing and sending water quality data or image data or sea current data of the aquaculture area; a transmitting antenna is arranged on the aquaculture net cage 6 and is in communication connection with the communication chip, the transmitting antenna is located on one side of the waterproof box body and is used for amplifying the strength of the monitoring data signal sent by the communication chip.

[0055] Specifically, in the technical solutions adopted in the present application, the communication assembly based on the first monitoring component 41, the second monitoring component 42 and the third monitoring component 43 can include three communication components, so that the first monitoring component 41, the second monitoring component 42 and the third monitoring component 43 can be connected with the corresponding communication components through the watertight communication cable. When the three communication components receive the corresponding aquaculture area data, such as water quality data, image data and sea current data, the data is converted and sent to the monitoring personnel, thereby achieving the purpose of real-time monitoring of the aquaculture area.

[0056] In one embodiment, the communication component can include a waterproof box, a communication chip is arranged in the waterproof box, the waterproof box can avoid the short circuit caused by the contact between seawater and the communication chip, the communication chip is responsible for receiving the water quality data, image data and sea current data obtained by the monitoring assembly 4 in the water, and sending the converted data; and the sending antenna is arranged on the net cage 6, the sending antenna is located on one side of the waterproof box, when the communication chip sends the monitoring data, the sending antenna can amplify the transmitted signal to improve the communication ability of the communication component, effectively improve the stability of the monitoring device, and avoid the data damage or data loss caused by weak signal source when receiving the signal.

[0057] The communication chip in the present embodiment compares the sea current data after receiving the data with the communication chip connected to the first monitoring component 41, the preset safe flow rate and flow direction range, and once the comparison result exceeds the preset range, the early warning process is started; the communication chip connected to the second monitoring component 42 triggers the early warning when the dissolved oxygen, temperature, pH value and the like deviate from the suitable interval according to the water quality parameter standard suitable for different fish; the fish size data combined with the growth cycle model, if the growth is slow or the size difference is abnormally increased, a prompt is sent; the communication chip connected to the third monitoring component 43 can perform data cleaning, specifically removing abnormal values and noise interference. In the present application, the aquaculture farmers can be informed in various ways such as audible and visual alarm, mobile phone message push, so that they can take timely measures such as adjusting the position of the net cage, changing water, adjusting the feeding strategy and the like.

[0058] In use, before being put into the field, the monitoring assembly 4 is fixedly installed on the third frame body 13 of the bearing bracket 1, then the communication components are connected to the corresponding first monitoring component 41, second monitoring component 42 and third monitoring component 43 through the water-tight communication cable and are tested for on-off, after the test is completed, the bearing bracket 1 is hung and placed in the middle position of the net cage 6. After one cycle of monitoring task is completed, the hitching component 3 tied to the net cage 6 is untied, the bearing bracket 1 is pulled out of the water surface and dragged to the edge of the net cage 6 for extraction.

[0059] Since the monitoring device of the present application is simple in design and easy to operate on site, it is not only suitable for underwater environmental monitoring of deep-sea net cages 6, but also suitable for water body environmental monitoring of net cages 6 close to the coastline, only adaptive adjustment of the monitoring device is needed according to the structure of the net cage 6.
