Description

TECHNICAL FIELD

[0001] The present application relates to the underwater fish monitoring technical field, and in particular to a fish monitoring device. BACKGROUND

[0002] With the improvement of people's living standards, aquatic product breeding has become a hot spot. The existing marine breeding industry mainly adopts the extensive fishery breeding mode based on breeding net cages. Meanwhile, due to the restriction of the development level of underwater fish monitoring equipment, people are difficult to accurately judge the size, type and health degree of underwater fish, which results in low fishery breeding efficiency and low breeding quality.

[0003] Traditional fish monitoring equipment mainly includes two types: one type adopts a sonar system to detect fish and then generates corresponding fish images. However, the sonar equipment is expensive and the data processing process is complicated. Moreover, underwater fish distribution is complex, and the sonar detection is easily affected by external environment, which leads to chaotic echo and cannot effectively distinguish fish and scenes, and cannot identify the size and variety of fish, and cannot give results for the health status of fish. Another type is to monitor and shoot the distribution of underwater fish through a shooting head and an underwater camera. However, due to the wide range and fast speed of underwater fish, the shooting camera is affected by underwater light and shooting distance, and the shot picture is blurred or seriously distorted. Meanwhile, the shooting camera also faces the operation restrictions such as focusing and angle adjusting, and has poor operability and cannot give specific physiological information and health status of single fish.

[0062] The technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0063] The present invention provides a fish monitoring device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of the present invention. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0064] Example 1

[0065] like Figure 1 As shown, in some embodiments of the present invention, a fish monitoring device is provided for monitoring fish. The fish monitoring device includes: a main body 1, through which a fish passage 11 is provided, the fish passage 11 being used for fish to enter or leave the main body 1; a camera module (unlabeled), disposed on the peripheral wall 111 of the fish passage 11, for photographing fish entering the fish passage 11; wherein, the camera module has a camera mechanism 21 and an actuation mechanism (unlabeled), the camera mechanism 21 being fixed to the actuation mechanism, the actuation mechanism being disposed on the peripheral wall 111 of the fish passage 11, and being used to sense the fish and drive the camera mechanism 21 to rotate relative to the fish passage 11, so as to adjust the field of view of the camera mechanism 21. Specifically, the fish follows the path shown in the diagram. Figure 1 When a fish enters the fishway 11 in the direction indicated by the arrow and is within the field of view of the shooting mechanism 21, the shooting mechanism 21 takes a picture of the fish. As the fish continues to move along the arrow and gradually moves away from the original field of view of the shooting mechanism 21, the actuation mechanism senses the change in the fish's position and then controls the shooting mechanism 21 to rotate so that its field of view faces the fish's newest position. This enables the shooting mechanism 21 to automatically track and photograph the moving fish, significantly increasing the monitoring range of the fish and thus enhancing the monitoring effect. This allows observers to better obtain parameters such as the fish's health status. Furthermore, the fish monitoring device provided by this invention has the advantages of low cost, easy assembly, easy operation, and good versatility, making it easy to promote.

[0066] Because underwater fish have a wide range of movement and swim fast speeds, the images captured by the camera are often blurry or severely distorted due to underwater lighting and shooting distance. Furthermore, the camera faces limitations in operation, such as focusing, resulting in poor operability and an inability to provide specific physiological information and health status of individual fish. The fish monitoring device provided by this invention captures images of fish within the fishway 11, shortening the shooting distance and thus providing clearer images.

[0067] refer to Figure 2 Other embodiments of the present invention provide a different structural form of the fish monitoring device, which also includes the aforementioned main body 1.

[0068] It can be understood that the above-mentioned shooting mechanism 21 includes a camera with a photographing function, and a video camera with a video recording function. The specific equipment of the camera or the video camera and the specific parameters are determined according to the actual application requirements. The observer can select and adjust according to the actual situation. More specifically, the above-mentioned shooting mechanism 21 can be a monocular camera or a binocular camera.

[0069] It can be understood that the peripheral wall 111 of the fishway 11 includes a bottom surface located at the bottom of the main body 1, a side surface located at the side of the main body 1, and a top surface located above the main body 1. The above-mentioned shooting mechanism 21 can be arranged on the bottom surface, the side surface and the top surface to monitor the fish from below, from the side and from above, respectively, so as to better understand the overall situation of the fish and perform corresponding health assessment.

[0070] As shown in Figure 1 , in some embodiments of the present application, the actuating mechanism includes a sensing assembly arranged on the peripheral wall 111 of the fishway 11 and used for sensing the moving state of the fish, and an actuating assembly arranged on the peripheral wall 111 of the fishway 11 and magnetically connected with the sensing assembly and fixedly connected with the shooting mechanism 21. The sensing assembly senses the motion information of the fish including the moving position, etc., and then magnetically attracts and drives the actuating assembly, and then drives the shooting mechanism 21 to rotate. Specifically, the sensing assembly in the actuating mechanism senses the state that the fish moves in the direction indicated by the arrow in Figure 1 , and then adjusts the actuating assembly to make corresponding actions according to the moving state of the fish, so as to control the shooting mechanism 21 to rotate and change the shooting field of view, so as to realize the function of automatically tracking and shooting the moving fish, and increase the monitoring range of the fish entering the fishway 11, and obtain better monitoring effect.

[0071] As shown in Figure 1As shown, in some embodiments of the present invention, the sensing component includes: a first light-emitting element 2211 and a photosensitive element 2212, which are disposed opposite to each other on the peripheral walls 111 on both sides of the fish passage 11; an electromagnetic element 2213, which is fixed on the peripheral wall 111 of the fish passage 11 and electrically connected to the photosensitive element 2212, wherein the electromagnetic element 2213 magnetically attracts and drives the actuation component according to the state of the photosensitive element 2212. Specifically, the first light-emitting element 2211 emits light and illuminates the photosensitive element 2212. At this time, the illuminated area of ​​the photosensitive element 2212 is at its maximum, and the photosensitive element 2212 is in a first electrical state. As the fish gradually approaches between the first light-emitting element 2211 and the photosensitive element 2212, the fish gradually blocks the light emitted by the first light-emitting element 2211, causing the illuminated area on the photosensitive element 2212 to gradually decrease, and the photosensitive element 2212 then transitions to a second electrical state. The photosensitive element 2212 switches between the first and second electrical states, thereby regulating the magnetic strength of the electromagnetic element 2213. The fish monitoring device provided by this invention controls the action of the actuating components based on the change in the magnetic strength of the electromagnetic element 2213, thereby controlling the shooting mechanism 21 to adjust its shooting field of view to achieve the function of tracking and shooting moving fish. Specifically, the aforementioned electrical state can refer to the magnitude of current or voltage. Correspondingly, a change in electrical state refers to a change in the magnitude of current or a change in the magnitude of voltage.

[0072] like Figure 1 As shown, in some embodiments of the present invention, the actuating component includes: a fixed bracket 2221, fixedly mounted on the peripheral wall 111 of the fish passage 11, serving to fix, connect, and support other components; a lever 2222, comprising a first end, a fulcrum, and a second end, wherein the first end of the lever 2222 is fixedly connected to the shooting mechanism 21, the fulcrum is rotatably connected to the fixed bracket 2221, and a magnetic element 22224 is fixedly mounted on the second end of the lever 2222; and an elastic connector 2223, one end of which is connected to the peripheral wall 111 of the fish passage 11, and the other end of which is connected to the lever 2222 at a position between the fulcrum and the second end; wherein the elastic connector 2223 and the electromagnetic element 2213 are located on opposite sides of the lever 2222. It is understandable that the aforementioned magnetic element 22224 and elastic connector 2223 control the rotation of the shooting mechanism 21 through the lever 2222 and the lever principle, thereby enabling the control of the shooting field of view of the shooting mechanism 21.

[0073] Specifically, when the fish is not located between the first light-emitting element 2211 and the photosensitive element 2212, the magnetic attraction force of the electromagnetic element 2213 controlled by the photosensitive element 2212 is equal to the elastic force of the elastic connector 2223. At this time, the lever 2222 is in a position as follows: Figure 1The center position is shown, and the elastic connecting piece 2223 is in a stretched state; when the fish enters the position between the first light emitting element 2211 and the light receiving element 2212, the area of the light receiving element 2212 blocked by the fish gradually increases, and the area of the light receiving element 2212 irradiated by the first light emitting element 2211 decreases, and the magnetic attraction of the electromagnetic element 2213 decreases, at this time the external force received by the elastic connecting piece 2223 decreases and the elastic connecting piece 2223 shortens its size and pulls the second end of the lever 2222 to the right side as shown Figure 1 , at the same time the first end of the lever 2222 rotates to the left side as shown Figure 1 , so that the shooting field of view of the shooting mechanism 21 turns to the side provided with the light receiving element 2212 to align the fish that has moved close to the area where the light receiving element 2212 is located, so as to realize the adaptive tracking shooting observation of the fish by the shooting mechanism 21. Compared with the existing monitoring device without the above-mentioned actuating mechanism, the fish monitoring device provided by the present application has a larger monitoring range and shooting range, and realizes real-time adaptive tracking effect for the moving fish entering the fishway 11, significantly improving the monitoring ability and effect of the fish.

[0074] And when the fish leaves the device in the direction indicated by the arrow in Figure 1 , the irradiated area of the light receiving element 2212 returns to the maximum, at this time the magnetic attraction of the electromagnetic element 2213 to the magnetic element 22224 increases, and the elastic connecting piece 2223 is stretched again to the position as shown Figure 1 , at this time the lever 2222 returns to the original central position under the balance of the magnetic attraction from the electromagnetic element 2213 and the elastic force from the elastic connecting piece 2223 as shown Figure 1 , finally making the shooting mechanism 21 return to the original shooting angle, that is, making the shooting field of view of the shooting mechanism 21 return to the state before the fish blocks the light receiving element 2212, so as to carry out the next tracking shooting action when a new fish enters the fishway 11, that is, the combination of the above-mentioned elastic connecting piece 2223 and the electromagnetic element 2213 also has the function of resetting the shooting field of view of the shooting mechanism 21.

[0075] Specifically, as shown in Figure 1 , a through hole (not numbered) is formed in the peripheral wall 111, and the fixed support 2221 is transversely arranged in the through hole, so that the shooting mechanism 21 is located in the fishway 11 to shoot and monitor the fish in the fishway 11.

[0076] Specifically, in some embodiments of the present application, the elastic connecting member 2223 is a spring, the electromagnetic element 2213 is an electromagnet, the electromagnet has a magnetic pole, the magnetic pole attracts the magnetic element 22224; the magnetic pole and the spring are respectively located on both sides of the lever member 2222, and the magnetic force direction of the magnetic pole is the same as the stretching direction of the spring, so that the magnetic force direction on the lever member 2222 is opposite to the spring tension direction. It can be understood that the specific specifications and parameters of the spring, electromagnet and magnetic pole described above can be selected and adjusted according to the actual use situation.

[0077] Specifically, the distance between the spring and the fulcrum of the lever member 2222 is A, the distance between the magnetic element 22224 and the fulcrum of the lever member 2222 is B, and A:B = 1:(1-10); exemplary, the ratio can be A:B = 1:2, A:B = 1:3, A:B = 1:4, A:B = 1:5, A:B = 1:6, A:B = 1:8, so that the electromagnetic element 2213 can realize the control of the lever member 2222 with smaller magnetic force; the specific selection of the ratio is related to the specific specifications and parameters of the first light emitting element 2211, the light sensing element 2212, the electromagnetic element 2213, the magnetic element 22224 and the elastic connecting member 2223.

[0078] Reference Figure 1 And Figure 2 In some embodiments of the present application, the shooting module further comprises a protection mechanism 23; the protection mechanism 23 is fixedly arranged on the peripheral wall 111 of the fishway 11 and encloses a containing cavity (not numbered), the shooting mechanism 21, the actuating assembly and the electromagnetic element 2213 are all contained in the containing cavity. The protection mechanism described above plays the functions of waterproofing and protecting the shooting mechanism 21, the actuating assembly and the electromagnetic element 2213, and the specific shape, size and other parameters of the protection mechanism can be adjusted and designed according to the actual use environment.

[0079] As Figure 1As shown, in some embodiments of the present application, the protection mechanism 23 can be a split design, and the protection mechanism 23 includes a first protection shell 231 and a second protection shell 232; the first protection shell 231 is arranged on the peripheral wall 111 of the fishway 11, and encloses a first accommodating cavity (not numbered), the shooting mechanism 21 and the actuating assembly are accommodated in the first accommodating cavity, and the first protection shell 231 serves to protect the shooting mechanism 21 and the actuating assembly; the second protection shell 232 is arranged on the peripheral wall 111 of the fishway 11, and encloses a second accommodating cavity (not numbered), the electromagnetic element 2213 is accommodated in the second accommodating cavity, and the second protection shell 232 serves to protect the electromagnetic element 2213. Of course, in other embodiments of the present application, the first protection shell 231 and the second protection shell 232 can be connected by a channel or a pipeline to facilitate cable arrangement and other purposes.

[0080] In some embodiments of the present application, the first protection shell 231 penetrates the main body 1, the shooting mechanism 21 is located on one side of the first accommodating cavity in the fishway 11, the actuating assembly is located on the other side of the first accommodating cavity outside the main body 1, and the part of the first protection shell 231 located in the fishway 11 is transparent, so that the shooting mechanism 21 can shoot the fish in the fishway 11; the second protection shell 232 is located outside the main body 1, which is convenient for maintenance and can also reduce unnecessary components in the fishway 11 to occupy the space in the fishway 11.

[0081] In some embodiments of the present application, the fish monitoring device further includes a light attraction module to use the phototaxis of fish to attract the fish to swim into the fishway 11 spontaneously so as to facilitate the shooting mechanism 21 to shoot and observe the fish. Specifically, as shown, Figure 1 As shown, the light attraction module is fixedly arranged on the main body 1, and includes a second light emitting element 3; the second light emitting element 3 is arranged in the fishway 11 to emit light to attract the fish into the fishway 11.

[0082] In some embodiments of the present application, the second light-emitting element 3 is arranged at two ends of the fishway 11 in the longitudinal direction, respectively; or, the number of the second light-emitting element 3 arranged on the side of the photographing mechanism 21 away from the first light-emitting element 2211 is greater than the number of the second light-emitting element 3 arranged on the side close to the first light-emitting element 2211. The above design is to avoid the influence of the second light-emitting element 3 used for attracting fish on the photosensitive element 2212, and avoid the problem that when the fish is located between the first light-emitting element 2211 and the photosensitive element 2212, the photosensitive element 2212 is still irradiated by the second light-emitting element 3 nearby, so that the electrical state of the photosensitive element 2212 cannot be switched, and the magnetic force of the electromagnetic element 2213 cannot be changed, and finally the actuating assembly cannot adjust the photographing field of view of the photographing mechanism 21 to realize tracking and photographing observation.

[0083] As shown in Figure 1 some embodiments of the present application, the fish monitoring device further comprises a power supply 4; the power supply 4 is electrically connected with the photosensitive element 2212 and the electromagnetic element 2213, which makes the photosensitive element 2212 control the power intensity received by the electromagnetic element 2213, that is, the change of the electrical state of the photosensitive element 2212 can control the change of the magnetic force of the electromagnetic element 2213; the power supply 4 is electrically connected with the photographing mechanism 21, the first light-emitting element 2211 and the second light-emitting element 3, respectively, to realize the power supply of the above components by the power supply 4. The power supply 4 provided by the present application can supply power to the above multiple power-consuming components at the same time, so as to reduce the weight and manufacturing cost of the entire monitoring device. Specifically, the power supply 4 can be arranged outside the main body 1 for maintenance operation.

[0084] Specifically, the photosensitive element 2212 can adopt a photoresistor. When the irradiated area of the photoresistor changes, the resistance value of the photoresistor itself will change with the change of the irradiated area, and then the current or voltage received by the electromagnetic element 2213 will change, so as to change the magnetic force generated by the electromagnetic element 2213. More specifically, the photoresistor can adopt a photoresistor that does not decrease with the decrease of the irradiated area.

[0085] The fish monitoring device provided by the present application drives the electromagnet according to the characteristics of the photoresistor, remotely controls the movement of the lens without contacting the lens through the electromagnet, reduces unnecessary opening processing of the waterproof cover, automatically realizes the deflection of the camera lens by the activity of fish, makes the structure simpler, greatly reduces the operability, and avoids the problems of general controller not being waterproof and difficult underwater operation.

[0086] In some embodiments of the present application, the light induction module further comprises a receiver; the receiver is used for receiving control instructions or sensing environmental information, the receiver is electrically connected with the second light emitting element 3 and controls the light emitting parameters of the second light emitting element 3 according to the control instructions or the environmental information, so that the fish monitoring device can be used in water environments with different conditions, and can produce more attractive light to fish with different physiological conditions and attract them into the fishway 11 and expand tracking and shooting observation.

[0087] As shown in the drawings, Figure 1 In some embodiments of the present application, the main body 1 is further provided with a flow guide part 5; the flow guide part 5 includes two, and is respectively arranged at both ends of the main body 1, and is respectively connected with the fishway 11, so as to make the fish swim into the fishway 11.

[0088] Specifically, as shown in the drawings, Figure 1 In some embodiments of the present application, the flow guide part 5 is trumpet-shaped and has a narrow end 51 and a wide end 52 connected with each other; the narrow end 51 of the flow guide part 5 is connected with the main body 1, and the wide end 52 of the flow guide part 5 is arranged away from the main body 1, so as to make the fish swim into the fishway 11.

[0089] As shown in the drawings, Figure 1 In some embodiments of the present application, the wide end 52 of the flow guide part 5 is provided with a protection part 6 for preventing the fish from being injured. Specifically, the protection part 6 can be a rubber strip or the like.

[0090] Specifically, the first light emitting element 2211 and the second light emitting element 3 described above can adopt LED lamps, and the specific specification and parameters of the LED lamps depend on the actual use requirements.
