Description

Technical Field

[0001] The present application relates to the technical field of underwater operation equipment, and particularly relates to a fishing net device with an environmental monitoring function. Background Art

[0002] In marine aquaculture trawling operations, if the net can be aimed at the fish school for fishing, the economic benefits of fishing can be greatly improved, and a lot of blind consumption of manpower and material resources can be reduced. The key to solving this problem is how to obtain the water depth, the height of the net mouth, and the catch volume of the net in the water in real time and accurately. Therefore, monitoring the real-time state of the underwater environment near the fishing net is an important guarantee factor for improving the fishing efficiency of modern fisheries.

[0003] The related art discloses an aquaculture pond environmental monitoring and fish detection device, including a power supply mechanism, a data acquisition mechanism, a data receiving mechanism, a data transmission mechanism, a data storage mechanism, and a server. The data acquisition mechanism is sequentially connected to the server through the data receiving mechanism, the data transmission mechanism, and the data storage mechanism. The data acquisition mechanism includes: an underwater camera, which is slidably arranged inside the aquaculture pond through a vertical guide rail for obtaining fish images in the aquaculture pond; and a sensor acquisition unit for monitoring the aquaculture environment in the aquaculture pond. Although the related art realizes the collection of underwater-related information, the use environment is limited to the aquaculture pond. In the face of the ocean or other underwater environments with harsh conditions, the underwater camera will shake, and then the fish image lens received by the personnel on the water will also shake, making it difficult to analyze the fish situation. In addition, in the water, due to factors such as water flow or fish schools, the fishing net's netting may also block the lens of the underwater camera, resulting in affecting the imaging quality and subsequent analysis. Summary of the Invention

[0004] The purpose of the present invention is to provide a fishing net device with an environmental monitoring function to solve the technical problem that the underwater camera cannot clearly capture fish school information.

[0005] The present application provides a fishing net device with an environmental monitoring function, including:

[0006] An installation housing, installed on the fishing net;

[0007] An underwater wireless camera, installed on the installation housing, the underwater wireless camera is used to obtain environmental information near the fishing net, and an air cavity is provided on a side of the installation housing away from the underwater camera;

[0008] A sensor acquisition unit, installed on the fishing net, for monitoring the underwater environment;

[0009] A signal receiving unit, the signal receiving unit is electrically connected to the sensor acquisition unit and the underwater wireless camera respectively.

[0010] By adopting the above technical solution, the installation housing is installed on the fishing net, and an air cavity is formed on one side of the installation housing away from the underwater wireless camera. Since one end without the air cavity is heavier than the end with the air cavity, due to the buoyancy, when the imaging end of the underwater wireless camera shakes, it can drive the underwater wireless camera to quickly reset, thereby effectively improving the stability of the camera in the underwater environment.

[0011] Preferably, a transparent sphere is rotatably connected to the installation housing, a counterweight is arranged at a position away from the center of the sphere of the transparent sphere, the underwater wireless camera is installed in the transparent sphere, and the underwater wireless camera has an imaging end, and the imaging end can capture environmental images or videos near the fishing net through the transparent sphere.

[0012] By adopting the above technical solution, the underwater wireless camera is rotatably connected to the installation housing, reducing the influence of the shaking of the installation housing on the underwater wireless camera. At the same time, a counterweight is added to make the center of gravity of the transparent sphere away from the center of the sphere. When the installation housing shakes, the underwater wireless camera always maintains a relatively stable horizontal state.

[0013] Preferably, it further includes:

[0014] A paddle, which is slidably connected to the installation housing along the direction close to or away from the imaging end, and the paddles are symmetrically arranged on both sides of the imaging end;

[0015] A driving member, which is arranged on the installation housing and is used to drive the paddle to approach or move away from the imaging end.

[0016] By adopting the above technical solution, the paddle and the driving member are provided so that when the fishing net line blocks the lens of the underwater camera, the driving member can drive the oppositely arranged paddles to move from close to the imaging end to away from the imaging end, driving the paddles to push the fishing net line away from the lens, thereby improving the imaging quality of underwater monitoring.

[0017] Preferably, an installation notch is formed on the installation housing, the installation notch is close to the imaging end, and the paddle can slide on the installation housing provided with the installation notch.

[0018] By adopting the above technical solution, an installation notch is formed on the installation housing, enabling the paddle to slide on the installation housing, which is convenient for pushing the fishing net line obstructing the imaging end.

[0019] Preferably, the driving member includes:

[0020] An electric push rod, which is fixedly connected to the paddle, and the electric push rod is used to drive the paddle to approach or move away from the imaging end.

[0021] By adopting the above technical solution, an electric push rod is provided to push the paddle, and when the net wire of the fishing net obstructs the photographic end, the net wire of the fishing net is pushed away from the camera, thereby achieving the technical effect of improving the camera quality.

[0022] Preferably, the paddle is a magnetic member, and the driving member comprises:

[0023] A spring, one end of which is fixedly connected to the paddle;

[0024] An electromagnet, one end of which is fixedly connected to the mounting housing, and the other end of which can be magnetically connected to the magnetic member;

[0025] A waterproof cover is sleeved on the electromagnet, and an inner wall of the waterproof cover abuts against the electromagnet.

[0026] By adopting the above technical solution, when the fishing net wire blocks the camera end, when the electromagnet is energized, it will generate magnetic force to attract the paddle, and at the same time, under the action of the spring, the paddle is moved away from the camera end. In this way, the fishing net wire can be quickly opened to ensure that the camera's field of view is not blocked, thereby improving the camera quality.

[0027] Preferably, it also includes:

[0028] A rotating member is fixedly connected to the mounting shell and is used to drive the mounting shell to rotate.

[0029] By adopting the above technical solution, the folding between the fishing net and the mounting shell can be effectively prevented by driving the mounting shell to rotate through the rotating member. When the mounting shell is rolled into the fishing net and starts to rotate, the rotating member will drive the mounting shell to rotate instead of repeatedly interweaving and entangle the fishing net. This ensures the normal operation of the device and prevents the fishing net from folding and blocking the field of view of the camera end.

[0030] Preferably, the rotating member comprises:

[0031] A rotating column having a first pipe extending therethrough

[0032] A water pump is arranged in the first pipeline and fixedly connected to the rotating column, and is used for pumping water from one end of the first pipeline to the other end.

[0033] By adopting the above technical solution, the water pump draws water and transports it to the other end, and the water flow drives the mounting shell to achieve rotational movement. This can effectively prevent the folding between the fishing net and the mounting shell. When the mounting shell is drawn into the fishing net and starts to rotate, the rotating part will drive the mounting shell to rotate instead of repeatedly interweaving and entangle the fishing net. This ensures the normal operation of the device and prevents the folding of the fishing net from blocking the field of view of the camera end.

[0034] Preferably, a transparent window is installed on the mounting shell near the camera end.

[0035] By adopting the above technical solution, the camera end of the underwater wireless camera in the transparent sphere is prevented from being blocked by the installation shell.

[0036] Preferably, the sensor acquisition unit includes a temperature sensor, an oxygen content sensor, a pH sensor and a carbon and nitrogen content sensor, which are respectively used to measure the temperature, oxygen content, pH value and carbon and nitrogen content in water as environmental reference variables.

[0037] By adopting the above technical solution, temperature sensors, oxygen content sensors, pH sensors and carbon and nitrogen content sensors are set to measure environmental reference variables such as temperature, oxygen content, pH value and carbon and nitrogen content in water in real time. Through the monitoring of these sensors, the water ecological environment and aquaculture status can be accurately evaluated, and data support can be provided for protecting water ecology and improving aquaculture benefits. At the same time, the device has the ability of high-precision monitoring and continuous monitoring to promote the development of fisheries.

[0038] In summary, the present application includes at least one of the following beneficial technical effects:

[0039] 1. By setting up the installation shell, underwater wireless camera, sensor acquisition unit and signal receiving unit, the stability of the camera in the underwater environment is effectively improved, and the observation angle of the camera lens to the fish image is ensured to be stable;

[0040] 2. By setting the paddle and the driving member, the underwater wireless camera can always maintain a relatively stable horizontal state when the mounting housing shakes;

[0042] 4. By setting a rotating part, the rotating part will drive the mounting shell to rotate, instead of letting the fishing net be repeatedly intertwined and entangled, ensuring the normal operation of the device and preventing the fishing net from folding and blocking the camera's field of view.

[0050] The following Figure 1 - Figure 6 is further described in detail with reference to the attached drawings for this application.

[0051] Embodiment 1:

[0052] Referring to Figures 1 - 4 , a fishing net device with environmental monitoring function includes: installation housing 1, underwater wireless camera 2, sensor acquisition unit 3, signal receiving unit, paddle 4 and driving member 5.

[0053] Referring to Figure 1 and Figure 2 , the installation housing 1 is hoisted on the fishing net 8, the underwater wireless camera 2 is installed in the installation housing 1, the underwater wireless camera 2 is used to obtain the environmental information near the fishing net 8, and an air cavity 11 is opened on one side (upper part) of the installation housing 1 away from the underwater camera. Since one end without the air cavity 11 is heavier than the end with the air cavity 11, due to the buoyancy, when the camera end 21 of the underwater wireless camera 2 shakes, it can drive the underwater wireless camera 2 to quickly reset, thereby effectively improving the imaging stability of the camera in the underwater environment. In addition, a transparent window 7 is installed on the installation housing 1 near the camera end 21 to prevent the camera end 21 of the underwater wireless camera 2 in the transparent sphere 12 from being blocked by the installation housing 1.

[0054] Referring to Figure 1 and Figure 2, a transparent sphere 12 is rotatably connected inside the installation housing 1, and the underwater wireless camera 2 is installed inside the transparent sphere 12. The underwater wireless camera 2 has a camera end 21, and the camera end 21 can capture environmental images or videos near the fishing net 8 through the transparent sphere 12. When the installation housing 1 is impacted by eddies or fish schools, the underwater wireless camera 2 will still shake horizontally during reset. For this reason, the transparent sphere 12 is rotatably connected to the installation housing 1, and a counterweight 121 is arranged at a position of the transparent sphere 12 far from the center of the sphere. First, the underwater wireless camera 2 is rotatably connected to the installation housing 1 to reduce the influence of the shaking of the installation housing 1 on the underwater wireless camera 2. Because at this time, when the installation housing 1 shakes, the transparent sphere 12 can reduce the shaking amplitude by rolling. At the same time, the counterweight 121 is added to make the center of gravity of the transparent sphere 12 far from the center of the sphere. Using a technical principle similar to that of a tumbler, when the installation housing 1 shakes, the centers of gravity of the underwater wireless camera 2 and the counterweight 121 always remain in a relatively stable horizontal state (defining the parallel sea level or the horizontal plane as the horizontal state). At the same time, considering that when the installation housing 1 shakes, due to the rotatable connection, the camera end 21 of the underwater wireless camera 2 may rotate relatively in the horizontal direction. Therefore, when selecting a camera, a camera with a horizontal rotation function at the camera end 21 (camera lens) is selected to facilitate adapting to this complex environment.

[0055] Refer to Figure 2 and Figure 3 , the paddle 4 (which will not block the camera view of the camera end 21, and is shown slightly larger in the figure for easy understanding) is slidably connected to the installation housing 1 along the direction of approaching or departing from the camera end 21, and the paddle 4 is symmetrically arranged on the left and right sides of the camera end 21. The driving member 5 is arranged on the installation housing 1 and is used to drive the paddle 4 to approach or depart from the camera end 21. In this embodiment, the driving member 5 is an electric push rod 51, the electric push rod 51 is fixedly connected to the paddle 4, and the electric push rod 51 is used to drive the paddle 4 to approach or depart from the camera end 21. A power source (not shown in the figure) is arranged inside the installation housing 1, and the power source is electrically connected to the electric push rod 51. A switch is arranged on the electric push rod 51, and the switch is electrically connected to the control center of the personnel on the water surface. The control center can control the telescopic movement of the electric push rod 51, and further control the movement of the paddle 4. By setting the electric push rod 51 to push the paddle 4, when the fishing net line 81 obstructs the camera, the fishing net line 81 can be timely deflected away from the camera, thereby achieving the technical effect of improving the imaging quality.

[0056] Refer to Figure 3, an installation notch 13 is formed on the installation housing 1. The lowest point of the installation notch 13 is close to the imaging end 21. The paddle 4 can slide on the installation housing 1 where the installation notch 13 is formed. The installation notch 13 on the installation housing 1. An inclined chute 14 is formed on the installation notch 13. The inclined chute 14 communicates with the installation notch 13. The paddle 4 can slide relatively within the inclined chute 14, facilitating the toggling of the fishing net line 81 of the fishing net 8 that obstructs the imaging end 21. Meanwhile, to prevent the paddle 4 from loosening within the inclined chute 14, a limiting groove (not shown in the figure) is formed on the installation housing 1. The limiting groove communicates with the inclined chute 14. A limiting block adapted to the limiting groove is provided on the paddle 4. The limiting block is slidably connected to the limiting inclined chute 14. The inclined chute 14 on the installation notch 13 causes the paddle 4 to rise in a climbing shape within the installation notch 13. When not needed to be toggled, it is located at the lowest point of the inclined chute 14, ( Figure 4 in which the paddle 4 is in a climbing state, so the paddle 4 protrudes outside the installation housing 1) to prevent it from protruding outside the installation housing 1 when not needed to be toggled, resulting in the protruding paddle 4 obstructing the normal movement of the fishing net 8. When needed to be toggled, the driving member 5 drives the paddle 4 to climb, preventing the fishing net line 81 of the fishing net 8 from obstructing the imaging end 21.

[0057] Referring to Figure 4 , the sensor acquisition unit 3 is installed on the fishing net 8 and is used to monitor the underwater environment. The sensor acquisition unit 3 can cooperate with the underwater camera to obtain more environmental information. The sensor acquisition unit 3 includes a temperature sensor, an oxygen content sensor, a pH sensor, and a carbon-nitrogen content sensor, which are respectively used to measure the temperature, oxygen content, pH value, and carbon-nitrogen content in the water as environmental reference variables. By jointly analyzing the sensor data and the image data of the underwater camera, the condition of the underwater environment can be more comprehensively understood, and the distribution and behavior of fish can be inferred therefrom. Through the sensor acquisition unit 3, it is used to measure environmental reference variables such as the temperature, oxygen content, pH value, and carbon-nitrogen content in the water in real time. Through the monitoring of these sensors, the underwater ecological environment can be accurately evaluated, facilitating the monitoring of the numerical values of various underwater indicators and promoting the development of the fishery.

[0058] The signal receiving unit is located on the shore or on the ship and is controlled by the operator. The signal receiving unit is respectively connected to the sensor acquisition unit 3 and the underwater wireless camera 2 through a wireless receiver in a radio connection, facilitating the reception of information near the fishing net 8 underwater collected by the underwater wireless camera 2 and the sensor acquisition unit 3.

[0059] The implementation principle of this Embodiment 1:

[0060] When fishermen use the fishing net 8 device to fish, they use the underwater wireless camera 2 hoisted on the fishing net 8 to shoot the underwater environment. The sensor acquisition unit 3 is also installed on the fishing net 8 to monitor various underwater water quality information. The cavity on the upper part of the installation shell 1 makes the center of gravity biased towards the transparent sphere 12 located at the lower part. When the installation shell 1 shakes, it can be quickly reset. The transparent sphere 12 is connected to the installation shell 1 by rolling, and the counterweight 121 is close to the underwater wireless camera 2, so that even if the installation shell 1 shakes, the transparent sphere 12 can roll relative to the installation shell 1 due to the existence of the counterweight 121. At this time, the relative position of the transparent sphere 12 and the underwater wireless camera 2 in the transparent sphere 12 does not change. In addition, due to the water flow or the school of fish, when the net line 81 of the fishing net 8 blocks the lens of the camera, the driving member 5 can be used to adjust the paddle 4 so that the paddle 4 moves away from the camera end 21 to the direction away from the camera end 21 to avoid affecting the camera quality.

[0061] Example 2

[0062] Reference Figure 5 and Figure 6 , which is substantially the same as the first embodiment, except that the driving member 5 is different and a rotating member 6 is added.

[0063] Reference Figure 5 , the paddle 4 is a magnetic part, which can be made of iron sheet or other metal with magnetic attraction. The driving part 5 includes a spring 52, an electromagnet 53 and a waterproof cover 54. One end of the spring 52 is fixedly connected to the paddle 4, and the other end is fixedly connected to the mounting shell 1. One end of the electromagnet 53 is fixedly connected to the mounting shell 1, and the other end of the electromagnet 53 can be magnetically connected to the magnetic part. The waterproof cover 54 is sleeved on the electromagnet 53, and the inner wall of the waterproof cover 54 abuts against the electromagnet 53. A power supply (not shown in the figure) for supplying power to the magnet 53 is also provided in the waterproof cover 54, and a switch (not shown in the figure) for controlling the electromagnet 53 that is electrically connected to the electromagnet 53 is also provided in the control center on the shore or on the ship. When the net line 81 of the fishing net 8 does not hinder the camera end 21, the electromagnet 53 is in a working state, and the magnetic force generated by it attracts the paddle 4, so that the paddle 4 is close to the camera end 21. When the wire 81 of the fishing net 8 blocks the camera end 21, the electromagnet 53 is turned off, and its magnetic attraction to the magnetic part on the paddle 4 disappears. Due to the pulling force of the spring 52, the paddle 4 quickly moves away from the camera end 21. Then, the wire 81 of the fishing net 8 is quickly pushed aside to ensure that the camera's field of view is not blocked, thereby achieving the purpose of improving the camera quality. Compared with the driving scheme of the electric push rod 51 in the embodiment, the driving member 5 of the embodiment adopts a spring 52 and an electromagnet 53. The action of pushing the paddle 4 is realized by controlling the on and off of the electromagnet 53, and the wire 81 of the fishing net 8 is quickly pushed aside by the reset of the spring 52. In addition, a waterproof cover 54 is introduced to protect the electromagnet 53, which increases the durability and stability of the device.

[0064] Reference Figure 6 , the rotating member 6 is fixedly connected to the mounting shell 1, and the rotating member 6 is used to drive the mounting shell 1 to rotate. By driving the mounting shell 1 to rotate by the rotating member 6, the folding between the fishing net 8 and the mounting shell 1 can be effectively prevented. When the mounting shell 1 is drawn into the fishing net 8 and starts to rotate, the rotating member 6 will drive the mounting shell 1 to rotate instead of allowing the fishing net 8 to be repeatedly intertwined and entangled. Ensure the normal operation of the device, and at the same time prevent the fishing net 8 from folding and blocking the field of view of the camera end 21. Specifically, the rotating member 6 includes a rotating column 61 and a water pump 62. A first pipe 611 is provided on the rotating column 61, and the water pump 62 is arranged in the first pipe 611 and is fixedly connected to the rotating column 61, and is used to pump water from one end of the first pipe 611 to the other end. By pumping water with the water pump 62 and delivering it to the other end, the water flow can drive the mounting shell 1 to achieve rotational movement. When the mounting shell 1 is drawn into the fishing net 8 and starts to rotate, the rotating member 6 will drive the mounting shell 1 to rotate, thereby preventing the fishing net 8 from folding and thereby obstructing the field of view of the camera end 21.

[0065] The implementation principle of Example 2 of the present application is:

[0066] The implementation principle is substantially the same as that of Example 1, except that the paddle 4 is controlled by the electromagnet 53 and the spring 52, and the action of paddle 4 is achieved by controlling the on and off of the electromagnet 53, which is more efficient. At the same time, a rotating member 6 is provided to adjust the angle of the installation housing 1 to prevent the fishing net 8 from being repeatedly intertwined and entangled.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
