Description

Technical Field

[0001] The present invention relates to the technical field of underwater robots, and particularly to a device for investigating and monitoring fish communities in water ecosystems. Background Art

[0002] An underwater robot, also known as a remotely operated underwater vehicle (ROV), is an intelligent device used for operations in extreme underwater environments. Due to the complex and dangerous underwater environment and the limited diving depth of humans, such robots have become key tools for ocean resource development. Remotely operated underwater vehicles are mainly divided into two types: cabled and cable-free. Among them, cabled remotely operated underwater vehicles can be further subdivided into three categories: self-propelled in water, towed, and crawler-type that can crawl on underwater structures. The application fields of underwater robots are very extensive, including but not limited to the following scenarios: inspecting whether there are explosives or structural damages in dams and bridge piers; performing remote reconnaissance and close-range detection of dangerous goods; assisting in the installation and disassembly of underwater arrays; detecting attachments or damages on the side walls and bottoms of ship hulls; observing underwater targets and participating in search and rescue missions such as sunken ships and collapsed mines.

[0003] However, in the application of existing underwater robots to fish monitoring, the flexibility of most devices is very poor. For example, a fish monitoring device disclosed in the prior art (publication number CN222301900U) continuously pumps water from the water body through a water pump, filters it through a filter, and then transports it into a water tank to ensure the transparency of the water in the water tank. The one-way valve can prevent the water outside the water tank from entering the water tank through the water outlet, and at the same time, fish can freely enter and exit the water tank through the transmission channel in the one-way valve. The camera in the water tank can take pictures and videos of the fish entering the water tank, so as to obtain information on fish diversity.

[0004] Therefore, when the above fish monitoring device is applied to underwater fish monitoring, it often has the following disadvantages: the fish monitoring device is large and not portable, and there are many preparatory works during use. It is necessary for fish to pass through the device to take pictures and monitor the types of fish, and the contingency is too large, resulting in poor monitoring effects and being unsuitable for fish monitoring and identification. Summary of the Invention

[0005] The main purpose of the present invention is to overcome the deficiencies in the prior art and provide a device for investigating and monitoring fish communities in water ecosystems.

[0006] The technical solution adopted by the present invention to achieve its technical purpose is: a device for investigating and monitoring fish communities in water ecosystems, including a buoy assembly, an adjustment assembly, a circular rotation assembly, and a camera; The buoy assembly controls the floating or suspension of the fish community investigation and monitoring device; The adjustment component is arranged below the float component, and one end of the adjustment component is fixedly connected to the camera. The adjustment component enables the camera to adjust the shooting angle in a coordinate manner; The annular rotary component is arranged on the outer ring of the float component. The annular rotary component controls the movement and movement direction of the fish community investigation and monitoring device in the water.

[0007] Preferably, the float component includes an annular plate frame, an air chamber, an air pump, a retaining strip, a baffle, an airbag, a box body, a branch pipe, an electric valve and a main air pipe; A disc-shaped box body is arranged in the middle end of the annular plate frame. A plurality of baffles are arranged, and the baffles are evenly fixedly connected between the box body and the annular plate frame. One end of the baffle is fixedly connected to the outer wall of the box body, and the other end is fixedly connected to the inner wall of the annular plate frame; A retaining strip and an airbag are arranged between every two adjacent baffles. One end of the retaining strip is fixedly connected to the outer walls of the top end and the bottom end of the box body, and the other end is fixedly connected to the inner walls of the top end and the bottom end of the annular plate frame. The airbag is located in the space formed between the baffle and the retaining strip; through the arrangement of the baffle, the airbag is blocked and restricted from its left and right sides, and through the arrangement of the retaining strip, the airbag is blocked and restricted from its top and bottom. Through the combined arrangement of the baffle and the retaining strip, the shape of the airbag in the inflated state is shaped.

[0008] Preferably, the main air pipe is fixedly arranged in the middle end of the box body. A plurality of branch pipes are arranged, and one end of each branch pipe is evenly and fixedly communicated with the circumference of the main air pipe, and the other end passes through the box body and is fixedly communicated with the airbag. The main air pipe can inflate a plurality of branch pipes, so as to inflate the inside of the airbag.

[0009] A plurality of electric valves are arranged and are all located inside the box body. Each electric valve is independently and fixedly installed on the branch pipe; through the arrangement of the electric valve, the branch pipe can be controlled to be opened and closed. In order to ensure the balance of air inflation and deflation of the airbag, every two opposite electric valves are taken as a group, and the opening and closing of every two opposite electric valves are synchronously controlled.

[0010] Preferably, the air pump and the air chamber are both fixed on the top of the box body. The air pump is located inside the air chamber, and one end of the air pump is fixedly communicated with the main air pipe; through the arrangement of the air pump, it can inflate the main air pipe, the branch pipes and the airbag, and the air chamber is mainly used for storing or providing air to form a cycle.

[0011] Preferably, the annular rotary component includes an annular mounting plate, a driving gear ring, a turning wheel, a backing plate, a driving gear, a driving paddle, a connecting frame, an embedded slide rail, a chute, a limiting groove and a limiting block; The driving gear ring is sleeved outside the annular plate frame of the float assembly. A plurality of turning wheels are sleeved outside the driving gear ring and are meshed and connected therewith. A driving paddle is fixedly installed on one side of the turning wheel. The driving paddles are independently driven. When the whole device dives into water, rotation of the driving paddles can drive the whole device to move. The provision of a plurality of driving paddles facilitates individual control of the start and stop of the driving paddles, thereby facilitating change of the traveling direction.

[0012] A plurality of racks are integrally connected to the top of the driving gear ring. A meshing track groove matching the rack is formed inside the turning wheel. Rotation of the driving gear ring drives the turning wheel to rotate outside the driving gear ring, so as to adjust the angle of the driving paddle. As the turning wheel rotates on the driving gear ring, and the driving paddle is fixed to one side of the turning wheel, the driving paddle can flip its angle on the turning wheel. Therefore, when a single driving paddle starts, due to the change of the spraying angle of the driving paddle, the whole device can be inclined unilaterally, which is convenient for adjusting the shooting angle in cooperation with the camera.

[0013] Preferably, the annular mounting plate is fixedly sleeved on the outer wall of the annular plate frame. The annular mounting plate and the driving gear ring are connected at the bottom through a backing plate, an embedded slide rail and a chute. The embedded slide rail is embedded and slidably connected in the chute formed at the bottom of the driving gear ring. One side of one end of the backing plate is fixedly connected to the embedded slide rail, and the other end is directly fixedly connected to the outer wall of the annular mounting plate. Through the provision of the backing plate, the embedded slide rail and the chute, the driving gear ring can be slidably connected to the outer ring of the annular plate frame, and rotation of the driving gear ring can also be realized.

[0014] Preferably, a plurality of backing plates are symmetrically arranged between the annular mounting plate and the driving gear ring, and a driving gear for synchronous driving is fixedly installed on each backing plate. A tooth pattern groove is integrally formed inside the inner side of the driving gear ring. One side of the driving gear is meshed and connected with the tooth pattern groove on the inner side of the driving gear ring. Through the symmetrical arrangement of the backing plate and the driving gear ring on the annular mounting plate, the balance of the whole device is facilitated. The synchronous driving of the driving gears facilitates providing power to the driving gear ring simultaneously, so that the driving gear ring rotates.

[0015] Preferably, a T-shaped connecting frame is correspondingly arranged on the other side of the turning wheel, and annular limiting grooves are formed at both ends thereof. Limiting blocks matching the limiting grooves are fixedly arranged on both sides of one end of the connecting frame, and the other end is fixedly connected to the outer wall of the annular mounting plate. The limiting blocks are arranged in an arc structure and are fitted and connected in the limiting grooves. Through the limiting grooves and the limiting blocks, the turning wheel is slidably connected to one end of the connecting frame.

[0016] Preferably, the adjusting component includes a cross-shaped plate frame, a sphere, a first sliding groove, a second sliding groove, a first slider, a positioning seat, a first rotating frame, a second rotating frame, a second slider, a guide rod, and a servo motor; The cross-shaped plate frame is fixed at one end inside the wind shield. The end of the cross-shaped plate frame is bent, and an arc-shaped first rotating frame and a second rotating frame that cross each other are rotatably connected at the end. Trajectory grooves are provided inside both the first rotating frame and the second rotating frame; through the arrangement of the first rotating frame and the second rotating frame, it can rotate in the horizontal and vertical directions.

[0017] Two sets of servo motors are provided, which are respectively fixedly installed at the transverse end and the longitudinal end of the cross-shaped plate frame, and respectively drive the first rotating frame and the second rotating frame to rotate.

[0018] Preferably, an annular first sliding groove and a second sliding groove that cross each other are provided inside the sphere; One end of the sphere is slidably installed in the middle part of the cross-shaped plate frame through a first slider and a positioning seat; the first slider is slidably clamped inside the first sliding groove, and the positioning seat is fixed at the middle part of the cross-shaped plate frame; through the arrangement of the first sliding groove and the first slider, the sphere can move in the vertical direction.

[0019] The other end of the sphere is connected to the first rotating frame and the second rotating frame through a second slider and a guide rod; the second slider is slidably clamped inside the second sliding groove, the guide rod is fixed on one side of the second slider, one end of the guide rod is inserted at the intersection of the first rotating frame and the second rotating frame, and passes through the trajectory groove at the intersection of the first rotating frame and the second rotating frame and is fixed to the camera.

[0020] Through the arrangement of the second slider and the second sliding groove, the second slider can move horizontally in the second sliding groove; and then through the cooperation of the guide rod, the first rotating frame and the second rotating frame, the guide rod can move in multiple directions in the vertical and horizontal directions, its movement range is wider and more subtle, and the position is more accurate. At the same time, since both ends of the guide rod are restricted and supported, the supporting force of the guide rod is relatively balanced, so its stability is better, it will not shake easily, and it is more conducive to the stable shooting of the camera.

[0021] Compared with the prior art, the beneficial effects of the present invention are: For the fish community investigation and monitoring device in this water ecosystem, through the arrangement of the float component, the inclination angle of the camera can be adjusted by inflating and deflating the airbag, ensuring clear and effective vision, and the underwater height of the camera can be adjusted by inflating and deflating the airbag, realizing fixed water depth monitoring and improving adaptability.

[0022] The fish community investigation and monitoring device in this aquatic ecosystem, through the setting of the annular rotation assembly, can facilitate the horizontal movement and direction change of the overall device by driving a single driving paddle. Especially when changing directions, its steering efficiency is fast and the reaction is rapid. Moreover, the driving paddle can also tilt up and down longitudinally to change the spraying angle. When a single driving paddle is started, due to the thrust received on one side of the overall device, the overall device can tilt and move, and can tilt on one side, which is convenient for adjusting the shooting angle in cooperation with the camera to meet the shooting requirements under different conditions.

[0023] The fish community investigation and monitoring device in this aquatic ecosystem, through the setting of the adjustment assembly, can adjust the angle of the camera in a coordinate manner, improving the monitoring range, ensuring both accuracy and avoiding the problem of lens shaking during the movement or shooting of the camera, and improving the shooting efficiency and accuracy of the camera.

[0024] The fish community investigation and monitoring device in this aquatic ecosystem, through the coordinated setting of the buoy assembly, adjustment assembly, annular rotation assembly and camera, can not only dive into the water to follow the fish schools at multiple locations for dynamic shooting, but also requires little preparatory work in the early stage, is easy to use, has an intuitive and rapid monitoring effect on fish, has a fast reaction of the equipment, can monitor stably from multiple angles, has strong applicability, effectively eliminates the existing accidental errors, and makes the monitoring effect more accurate.

[0038] Please refer to Figures 1-9 , a fish community investigation and monitoring device in an aquatic ecosystem, including a floating component 1, an adjustment component 2, an annular rotation component 3, and a camera 4; The floating component 1 controls the fish community investigation and monitoring device to float or suspend; The adjustment component 2 is arranged below the floating component 1, and one end of it is fixedly connected to the camera 4.

[0039] It should be particularly pointed out that the fish community investigation and monitoring device in this aquatic ecosystem can be used in cooperation with a remote control and a power supply, and can be configured according to actual needs. For the adaptation of the power supply of existing underwater robots and the configuration of the remote control, conventional technologies can be used for adaptive settings according to the above-mentioned devices, and this application will not elaborate in detail. Example 2

[0040] Please refer to Figures 1-2 , on the basis of the above embodiment, for the fish community investigation and monitoring device in this aquatic ecosystem, the floating component 1 includes an annular plate frame 101, an air chamber 102, an air pump 103, a retaining bar 104, a baffle 105, an airbag 106, a box body 107, a branch pipe 108, an electric valve 109, and a main air pipe 110; A disc-shaped box body 107 is arranged in the middle of the annular plate frame 101. A plurality of baffles 105 are arranged, and they are evenly fixedly connected between the box body 107 and the annular plate frame 101. One end of the baffle 105 is fixedly connected to the outer wall of the box body 107, and the other end is fixedly connected to the inner wall of the annular plate frame 101; A retaining bar 104 and an airbag 106 are arranged between every two adjacent baffles 105. One end of the retaining bar 104 is fixedly connected to the outer walls of the top and bottom of the box body 107, and the other end is fixedly connected to the inner walls of the top and bottom of the annular plate frame 101. The airbag 106 is located in the space formed between the baffle 105 and the retaining bar 104; through the arrangement of the baffle 105, the airbag 106 is blocked and restricted from its left and right sides, and through the arrangement of the retaining bar 104, the airbag 106 is blocked and restricted from its top and bottom. Through the combined arrangement of the baffle 105 and the retaining bar 104, the shape of the airbag 106 in the inflated state is shaped.

[0041] Furthermore, in this embodiment, the main air pipe 110 is fixedly arranged in the middle of the interior of the box body 107. There are multiple branch pipes 108, and one end of each branch pipe is fixedly and uniformly connected to the circumference of the main air pipe 110, and the other end passes through the box body 107 and is fixedly connected to the airbag 106. Through the main air pipe 110, inflation can be carried out to multiple branch pipes 108, and thus inflation can be carried out into the interior of the airbag 106.

[0042] Both the air pump 103 and the air chamber 102 are fixed on the top of the box body 107. The air pump 103 is located inside the air chamber 102, and one end of the air pump 103 is fixedly connected to the main air pipe 110; through the arrangement of the air pump 103, it can inflate the main air pipe 110, the branch pipes 108, and the airbag 106, and the air chamber 102 is mainly used to store or provide air to form a cycle.

[0043] There are multiple electric valves 109, and all of them are located inside the box body 107. Each electric valve 109 is independently and fixedly installed on the branch pipe 108; through the arrangement of the electric valves 109, the branch pipes 108 can be controlled to be switched on and off. In order to ensure the balance of inflation and deflation of the airbag 106, every two opposite electric valves 109 are taken as a group to synchronously control the switching on and off of every two opposite electric valves 109.

[0044] Specifically, when in use, when it is necessary to control the floating and sinking state of the fish community investigation and monitoring device in the water ecosystem, by simultaneously opening multiple electric valves 109, the air pump 103 inflates the main air pipe 110, the branch pipes 108, and the airbag 106. Due to the arrangement of the baffle 105 and the stop strip 104, the airbag 106 can be blocked and restricted from its left and right sides as well as the up and down directions, so as to shape the shape of the airbag 106 when it is in the inflated state, making the overall structure of the airbag 106 roughly present a fan-shaped structure; When multiple airbags 106 are all filled with gas, the whole device can float on the water surface; When multiple airbags 106 all release gas, the whole device can sink into the water; When it is necessary to make the whole device suspended in the water, through the coordinated setting of every two opposite electric valves 109, synchronously controlling the switching on and off of every two opposite electric valves 109, any two opposite electric valves 109 can be simultaneously opened, and then the air pump 103 inflates the airbag 106 with the opened electric valve 109, so that the buoyancy received by the whole device increases, and thus the whole device can be suspended in the water; When it is necessary to adjust the suspension height of the whole device, by opening or closing different numbers of electric valves 109, the inflation and deflation of the airbag 106 are adjusted, so that the suspension height of the whole device can be adjusted.

[0045] The solution in this embodiment can be selectively combined and used with the solutions in other embodiments. Embodiment 3

[0046] Please refer to Figure 1 and Figures 3-6 Based on the above embodiments, for the fish community investigation and monitoring device in this aquatic ecosystem, the annular rotary assembly includes an annular mounting plate 301, a driving gear ring 302, a turning wheel 303, a backing plate 304, a driving gear 305, a driving paddle 306, a connecting frame 307, an embedded slide rail 308, a chute 309, a limiting groove 310 and a limiting block 311; The annular mounting plate 301 is fixedly sleeved on the outer wall of the annular plate frame 101. The annular mounting plate 301 and the driving gear ring 302 are connected at the bottom through the backing plate 304, the embedded slide rail 308 and the chute 309; the embedded slide rail 308 is embedded and slidably connected in the chute 309 opened at the bottom of the driving gear ring 302. One side of the backing plate 304 is fixedly connected to the embedded slide rail 308, and the other end is directly fixedly connected to the outer wall of the annular mounting plate 301; through the settings of the backing plate 304, the embedded slide rail 308 and the chute 309, the driving gear ring 302 can be slidably connected to the outer ring of the annular plate frame 101, and thus the rotation of the driving gear ring 302 can also be realized.

[0047] A plurality of backing plates 304 are symmetrically arranged between the annular mounting plate 301 and the driving gear ring 302, and a synchronously driven driving gear 305 is fixedly installed on each backing plate 304. A tooth pattern groove is integrally provided inside the inner side of the driving gear ring 302, and one side of the driving gear 305 is meshed with the tooth pattern groove on the inner side of the driving gear ring 302. Through the symmetrical settings of the backing plate 304 and the driving gear ring 302 on the annular mounting plate 301, the balance of the overall device is facilitated. The synchronous driving of the driving gears 305 facilitates providing power to the driving gear ring 302 simultaneously, causing the driving gear ring 302 to rotate.

[0048] The driving gear ring 302 is sleeved outside the annular plate frame 101 in the floating component 1, and a plurality of turning wheels 303 are sleeved and meshed outside the driving gear ring 302. A driving paddle 306 is fixedly installed on one side of the turning wheel 303; the driving paddle 306 is independently driven. When the overall device dives into the water, by rotating the driving paddle 306, the overall device can be driven to move. The setting of a plurality of driving paddles 306 facilitates individually controlling the start and stop of the driving paddle 306, and thus facilitates changing the traveling direction.

[0049] A number of racks are integrally connected to the top of the driving gear ring 302. A meshing track groove matching the racks is provided inside the turning wheel 303. By rotating the driving gear ring 302, the turning wheel 303 is driven to rotate outside the driving gear ring 302, so as to adjust the angle of the driving paddle 306. By rotating the turning wheel 303 on the driving gear ring 302, and the driving paddle 306 is fixed to one side of the turning wheel 303, the driving paddle 306 can be turned on the turning wheel 303. Thus, when a single driving paddle 306 is started, due to the change in the spraying angle of the driving paddle 306, the overall device can be tilted unilaterally, which is convenient for cooperating with the camera 4 to adjust the shooting angle.

[0050] A T-shaped connecting frame 307 is correspondingly arranged on the other side of the turning wheel 303, and annular limiting grooves 310 are provided at both ends thereof. Limiting blocks 311 matching the limiting grooves 310 are fixedly arranged on both sides of one end of the connecting frame 307, and the other end is fixedly connected to the outer wall of the annular mounting plate 301. The limiting blocks 311 are arranged in an arc shape and are fitted and connected in the limiting grooves 310, so that the turning wheel 303 is slidably connected to one end of the connecting frame 307 through the limiting grooves 310 and the limiting blocks 311.

[0051] Specifically, when in use, when the overall device dives into the water and is in a suspended state, by starting any one of the driving paddles 306 alone, the driving paddle 306 can push the overall device to move horizontally in one direction. When a direction change is required, the currently working driving paddle 306 can be closed, and the driving paddle 306 at other positions can be opened, so that the overall device moves in the required direction.

[0052] Moreover, when reaching the designated position, the turning wheel 303 can be rotated on the driving gear ring 302, and the driving paddle 306 is fixed to one side of the turning wheel 303, so that the driving paddle 306 can be turned on the turning wheel 303. Thus, when a single driving paddle 306 is started, due to the change in the spraying angle of the driving paddle 306, the overall device can be tilted unilaterally, so that the overall device moves obliquely, which is convenient for cooperating with the camera 4 to adjust the shooting angle.

[0053] The solution in this embodiment can be selectively combined and used with the solutions in other embodiments. Embodiment 4

One end of the guide rod 210 is inserted at the intersection of the first rotating frame 207 and the second rotating frame 208, and passes through the trajectory groove at the intersection of the first rotating frame 207 and the second rotating frame 208 to be fixed to the camera 4; Furthermore, through the cooperation of the guide rod 210, the first rotating frame 207, and the second rotating frame 208, the guide rod 210 can move in multiple directions in the vertical and horizontal directions. Its range of motion is more extensive and subtle, and the position is relatively accurate. At the same time, since both ends of the guide rod 210 are restricted and supported, the support force of the guide rod 210 is relatively balanced, so its stability is better, and it will not shake easily, which is more conducive to the stable shooting of the camera 4.

[0059] Specifically, when in use, when it is necessary to use the adjustment component 2 to adjust the shooting angle of the camera 4 and make the camera 4 stably adjusted, by rotating the first rotating frame 207, at this time, since the sphere 202 is restricted from lateral movement by the first slider 205 and the first chute 203, the sphere 202 does not move at this time, and the guide rod 210 drives the second slider 209 to move laterally in the second chute 204, so that the guide rod 210 can move laterally; Then, by rotating the second rotating frame 208, as the second rotating frame 208 moves longitudinally, since the second slider 209 is slidably clamped in the second chute 204, the second chute 204 is a horizontal annular groove, and the first slider 205 is slidably installed inside the first chute 203, and the first chute 203 is a longitudinal chute, so the second rotating frame 208 can drive the sphere 202 to move longitudinally, so that the guide rod 210 can move longitudinally; Therefore, through the combination of the above movements, the coordinate movement of the guide rod 210 can be realized, so that the range of motion of the camera 4 is more extensive and subtle, and the position is relatively accurate. At the same time, since both ends of the guide rod 210 are restricted and supported, the support force of the guide rod 210 is relatively balanced, so its stability is better, and it will not shake easily, which is more conducive to the stable shooting of the camera 4, effectively avoiding the problem that when the camera 4 adjusts the shooting angle, the shooting end of the camera 4 is prone to shaking or poor stability due to the resistance of water after the camera 4 is connected only by a single rod at its fixed end.

[0060] That is to say, in the existing camera 4, one end is fixedly connected by a single rod, and the single rod has no stable support, resulting in the problem of "top-heavy and bottom-light". However, the above camera 4 is not only connected to the middle and the top of the guide rod 210, but also the guide rod 210 is restricted and supported at both ends, so the overall stability is greatly enhanced, making the shooting lens of the camera 4 more stable.
