Description

Technical Field

[0001] This invention belongs to the field of biological monitoring technology, specifically a device and method for monitoring the abundance of aquatic organisms. Background Technology

[0002] Aquatic ecosystems refer to the ecosystems composed of aquatic biological communities and the aquatic environment. Aquatic ecosystems play a vital role in the human living environment. On the one hand, they play a crucial role in maintaining global material and water cycles; on the other hand, they also serve as water sources, power sources, transportation hubs, and pollution remediation sites. However, with the increasing impact of human activities on ecosystems, various aquatic ecosystems are in a state of long-term degradation, and their health is declining year by year.

[0003] With the decline in biodiversity in aquatic ecosystems, the material cycling network of the entire system has been disrupted, leaving it in a "sub-healthy" or "pathological" state. This reduces the ecological value of water bodies and exacerbates the global water crisis. Therefore, in order to fully understand the status of biological species resources in aquatic ecosystems, it is necessary to conduct biodiversity monitoring and assessment. The higher the biodiversity, the more stable the ecological environment and the more complete the ecosystem function in that region or ecosystem. Conversely, the lower the biodiversity, the more unstable the ecological environment and the less complete the ecosystem function. By monitoring and assessing biodiversity, we can provide a scientific basis for the next step of aquatic biodiversity protection, management, and decision-making.

[0004] To monitor and assess biodiversity, biodiversity monitoring equipment is required, but existing technologies rarely mention such equipment. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an aquatic organism abundance monitoring device and method.

[0006] The technical solution of the present invention is: an aquatic organism richness monitoring device, comprising a monitoring support frame, a height adjustment component disposed on the monitoring support frame, a fishing monitoring body connected to the height adjustment component, and an intelligent detection component disposed within the fishing monitoring body;

[0007] The monitoring support frame includes multiple distributed support rods, a cross folding frame located between two adjacent distributed support rods with its upper end fixedly connected to the distributed support rod via a fixed sleeve and its lower end slidably connected to the distributed support rod via a sliding sleeve, and a folding buckle plate connected to the upper end of each distributed support rod. The folding buckle plate is formed by hinged ends of multiple sub-folding buckle plates, and each sub-folding buckle plate is provided with a solar panel at its upper end.

[0008] The height adjustment assembly includes a vertical limiting groove connected to the side wall of each sliding sleeve, a connecting block slidably connected to the inner wall of the vertical limiting groove via a sliding block, and a first hydraulic cylinder that drives the sliding block to slide up and down within the vertical limiting groove.

[0009] The fishing monitoring body includes a fishing monitoring box connected to the side wall of the connecting block, multiple fishing inlets located at the bottom of the side wall of the fishing monitoring box, a release port located at the bottom of the fishing monitoring box, and a mounting frame for a baiting filler box located inside the fishing monitoring box with a side wall corresponding to each of the fishing inlets. Multiple one-way valves are hinged in each fishing inlet, and the free ends of each one-way valve are close to the side closer to the inside of the fishing inlet. An automatic opening and closing plate is provided at the release port. The baiting filler box has a mesh structure and a release cover is hinged to the side wall.

[0010] The intelligent detection component includes a microprocessor, a first camera and a recognition and counting module located in each trapping packing box and connected to the microprocessor, and a signal transmitter and receiver connected to an external control center via wireless signal.

[0011] Furthermore, the monitoring support frame also includes a sliding folding frame, which is composed of multiple sliding folding rods that correspond one-to-one with the distributed support rods. One end of each sliding folding rod is connected to the corresponding sliding folding rod through a sliding sleeve, and the other end is hinged to the side wall of the mounting plate. A second camera is provided at the bottom of the distributed mounting plate.

[0012] Instructions: When using the sliding folding frame, slide the corresponding sliding sleeves on each sliding folding rod downwards along the distribution support rods. At this time, each sliding folding rod unfolds with each other, and the second camera monitors the habitat of aquatic animals. When the sliding folding frame is finished, push the sliding sleeves upwards along the corresponding distribution support rods to fold the frame, saving space and increasing transportation convenience.

[0013] Furthermore, the bottom end of the sub-folding buckle plate located at the edge is provided with a connection port, and an elastic insertion rod is provided through the side wall of the connection port. The upper end of each of the distribution support rods is inserted into the connection port, and an insertion fixing hole is provided on the side wall of the distribution support rod corresponding to the position of the elastic insertion rod.

[0014] Instructions: When the folding panel is connected to each distribution support rod, pull the elastic plug rod outward to abut each distribution support rod against the corresponding connection port. Then, release the elastic plug rod and insert it into the plug fixing hole to fix the folding panel to each distribution support rod. This makes it easy to unfold the folding panel, increase the contact area between the solar panel and the sun, improve the energy storage effect, and the above structure is simple and easy to operate.

[0015] Furthermore, multiple buffer clamping plates are respectively provided on the left and right sides of the vertical limiting slide groove. The buffer clamping plates on the left and right sides of the vertical limiting slide groove are paired and distributed opposite each other. Each buffer clamping plate is connected to the inner wall of the vertical limiting slide groove through a second hydraulic cylinder. Multiple insertion posts are provided on the side wall of the buffer clamping plate on the side opposite to the second hydraulic cylinder. Buffer insertion holes are provided on the side wall of the sliding block corresponding to the positions of each insertion post. Each buffer clamping plate is provided with an infrared detector.

[0016] Instructions: When the height adjustment component is in use, the first hydraulic cylinder is activated, which drives the sliding block to move up and down within the vertical limiting groove. This adjusts the height of the connecting block and the fishing monitoring box, enabling the fishing and abundance monitoring of aquatic animal species at different depths. When the sliding block reaches the desired height, an infrared detector detects a signal and activates two second hydraulic cylinders at the corresponding height. The two relatively distributed second hydraulic cylinders move closer together, causing the corresponding buffer clamping plates to clamp the sliding block, dispersing the external force on the second hydraulic cylinders, increasing the connection reliability of the first hydraulic cylinder, and extending its service life.

[0017] Furthermore, the mounting frame includes an inverted T-shaped mounting rod fixedly connected to the top of the fishing monitoring box, a feeding box sleeved outside the vertical section of the inverted T-shaped mounting rod with multiple through-connection ports evenly distributed along the circumference of the side wall corresponding to the fishing inlet, an inclined feeding pipe with one end connected to the through-connection port and the other end connected to the trapping filler box, and a feeding opening and closing cover plate provided at the upper end of the feeding box.

[0018] Instructions: When bait needs to be placed into each bait box, open the baiting cover and add bait into the empty bait box through the cover. After entering the empty bait box, the bait falls through the various through-connection ports and corresponding inclined feeding pipes, and is transported to the corresponding bait box. Since the bait boxes are distributed at each fishing inlet, they can lure aquatic animals into the empty bait box through the fishing inlet. The identification and counting module identifies and counts specific aquatic animals, thereby monitoring the abundance of a certain aquatic animal at each habitat. In the above process, by setting up bait boxes, the aquatic animals at the habitat can enter the fishing monitoring box, which is convenient for identification and counting, increasing the convenience of biological abundance monitoring.

[0019] Furthermore, the trapping packing box is equipped with a weight sensor, and the bottom of the empty feeding box is equipped with a sprinkling protrusion, with a vibrator at the bottom of the sprinkling protrusion.

[0020] Explanation: By installing a weight sensor inside the bait box, the remaining amount of bait can be monitored in real time, facilitating timely replenishment and ensuring the continuity of the overall operation and the accuracy of bait abundance monitoring. By installing a feeding protrusion at the bottom of the feeding box, the bait can be tilted and dropped to each through-connection, preventing bait accumulation inside the feeding box and reducing cleaning frequency. By installing a vibrator, the remaining bait on the feeding protrusion can be shaken, increasing the bait falling rate and improving the working efficiency of the device.

[0021] Furthermore, the intelligent detection component includes a battery pack connected to the solar panel, a power detection module connected to the battery pack, and a power switching module.

[0022] Description: The battery pack stores the electrical energy converted from the solar panels, facilitating real-time use of electricity. The power detection module monitors the remaining power of the battery pack for timely charging. The power switching module facilitates switching with the grid, ensuring continuous operation of the device during cloudy days and improving operational reliability.

[0023] Furthermore, the sidewall of the one-way valve disc is provided with an elastic anti-collision layer, and the elastic anti-collision layer is a detachable structure. The automatic opening and closing plate is provided with a filtrate opening, and a filtrate screen is provided at the filtrate opening.

[0024] Explanation: By setting up an elastic anti-collision layer, direct collisions between aquatic animals and the various one-way valve discs are prevented, thus avoiding damage to the aquatic animals. By setting up a filter screen on the automatic opening and closing plate, the water entering the fishing monitoring box can be easily filtered out, reducing the load-bearing capacity of the inverted T-shaped mounting rod and increasing the installation reliability of the inverted T-shaped mounting rod.

[0025] This invention also discloses a method for monitoring the abundance of aquatic organisms, based on the aforementioned aquatic organism abundance monitoring device, comprising the following steps:

[0026] S1. When the monitoring support frame is not in use, each distributed support rod is close together and in a folded state. When it is necessary to unfold the monitoring support frame, move the sliding sleeve upwards to unfold each cross folding frame in the horizontal direction. At this time, the monitoring support frame is in the unfolded state. Unfold the folding buckle plate that is in the folded state and connect the folding buckle plate to the upper end of each distributed support rod so that each solar panel is laid flat and unfolded, and the solar energy is converted into electrical energy.

[0027] S2. Set the depth of the water to be monitored in advance, and start the first hydraulic cylinder through the microprocessor. The first hydraulic cylinder drives the sliding block to move up and down in the vertical limit groove to adjust the height of the connecting block and the fishing monitoring box. When the preset depth is reached, the first hydraulic cylinder is turned off.

[0028] S3. Open the release cover and release bait into each trapping box. The bait will cause aquatic animals in the area to enter the trapping monitoring box through the trapping inlet and open each one-way valve. At this time, the first camera will take pictures of the aquatic animals entering the trapping monitoring box and transmit them to the identification and counting module. The identification and counting module will identify and count specific species of aquatic animals. Each trapping monitoring box corresponds to a habitat, thereby monitoring the abundance of specific species of aquatic animals at each habitat. The signal will be sent to the external control center through the signal transmitter and receiver.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] (1) The aquatic organism richness monitoring device provided by this invention, when in use, saves the overall space occupied by the device by setting an unfoldable and foldable monitoring support frame and folding buckle plate, and also disassembles the various parts of the device for easy transportation. When the main body of the fishing monitoring device is in use, the sliding block can be driven by the first hydraulic cylinder to move up and down in the vertical limiting slide groove, thereby adjusting the height of the connecting block and the fishing monitoring box, so as to complete the fishing and richness monitoring of aquatic animal species at different depths. By setting the fishing inlet on the side wall of the fishing monitoring box, the richness monitoring of the habitat point can be achieved. Aquatic animals force open the closed one-way valves at each fishing inlet and enter the fishing monitoring box. By trapping aquatic animals in the fishing monitoring box, the area they move in is greatly reduced, which facilitates counting and identification and avoids repeated movement of aquatic animals between different habitats, thus improving the accuracy of monitoring. This improves the equipment's monitoring accuracy of the richness of characteristic species and enhances operational reliability. In addition, each fishing inlet is equipped with a trapping packing box, which allows aquatic animals at that habitat to automatically enter the fishing monitoring box, increasing the convenience of biodiversity monitoring.

[0031] (2) By pulling the elastic plug rod outward, each distribution support rod is abutted against the corresponding connection port. Then, the elastic plug rod is released and inserted into the plug fixing hole, so that the folding buckle is fixedly connected to each distribution support rod. This makes it easy to unfold the folding buckle, increase the contact area between the solar panel and the sun, improve the energy storage effect, and the above structure is simple and easy to operate.

[0032] (3) After the height of the connecting block and the fishing monitoring box is adjusted, the two second hydraulic cylinders at the corresponding height are activated after the signal is detected by the infrared detector. The two relatively distributed second hydraulic cylinders move closer to each other, so that the corresponding buffer clamping plate clamps the sliding block, decomposes the external force on the second hydraulic cylinder, increases the connection reliability of the first hydraulic cylinder, and extends its service life.

[0033] (4) By setting a weight sensor in the trapping packing box, it is convenient to monitor the remaining amount of bait in the trapping packing box in real time, so as to add it in time and ensure the continuity of the overall operation of the device and the accuracy of the richness monitoring. By setting a sprinkling protrusion at the bottom of the feeding box, it is convenient for the bait to fall at each through connection point, avoiding the accumulation of bait in the feeding box and reducing the cleaning frequency. By setting a vibrator, it is convenient to shake the remaining bait on the sprinkling protrusion, increase the falling rate of the bait and improve the working efficiency of the device.

Detailed Implementation

[0043] To further understand the content of the present invention, the present invention will be described in detail below through embodiments.

[0044] Example 1

[0045] like Figure 1 , 2 As shown in Figures 3 and 4, an aquatic organism richness monitoring device includes a monitoring support frame 1, a height adjustment component 2 mounted on the monitoring support frame 1, a fishing monitoring body 3 connected to the height adjustment component 2, and an intelligent detection component 4 mounted inside the fishing monitoring body 3.

[0046] The monitoring support frame 1 includes four distributed support rods 10, a cross folding frame 11 located between two adjacent distributed support rods 10 with its upper end fixedly connected to the distributed support rod 10 via a fixed sleeve 110 and its lower end slidably connected to the distributed support rod 10 via a sliding sleeve 111, and a folding buckle plate 12 connected to the upper end of each distributed support rod 10. The folding buckle plate 12 is formed by hinged together six sub-folding buckle plates 120, and each sub-folding buckle plate 120 is provided with a solar panel 121 at its upper end.

[0047] The height adjustment assembly 2 includes a vertical limiting slide groove 20 connected to the side wall of each sliding sleeve 111, a connecting block 21 slidably connected to the inner wall of the vertical limiting slide groove 20 via a sliding block 210, and a first hydraulic cylinder 22 that drives the sliding block 210 to slide up and down within the vertical limiting slide groove 20.

[0048] like Figure 5 As shown, the fishing monitoring body 3 includes a fishing monitoring box 30 connected to the side wall of the connecting block 21, four fishing inlets 31 located at the bottom of the side wall of the fishing monitoring box 30, a release port 32 located at the bottom of the fishing monitoring box 30, and a mounting bracket 33 located inside the fishing monitoring box 30 with a side wall having a trapping filler box 330 corresponding to each fishing inlet 31. Each fishing inlet 31 is hinged with five one-way valves 310, and the free ends of each one-way valve 310 move closer to the inside of the fishing inlet 31. An automatic opening and closing plate 320 is provided at the release port 32. The trapping filler box 330 has a mesh structure and a release cover plate 331 is hinged to the side wall.

[0049] The intelligent detection component 4 includes a microprocessor 40, a first camera 41 and an identification and counting module 42 located in each trapping packer box 330 and connected to the microprocessor 40, a signal transmitter and receiver 43 connected to an external control center via a wireless signal, a battery pack 44 connected to the solar panel 121, a power detection module 45 and a power switching module 46 connected to the battery pack 44.

[0050] like Figure 5 As shown, the mounting frame 33 includes an inverted T-shaped mounting rod 332 fixedly connected to the top of the fishing monitoring box 30, a feeding empty box 333 sleeved on the outside of the vertical section of the inverted T-shaped mounting rod 332 and having four through connection ports 3330 that correspond one-to-one with the fishing inlet 31 evenly arranged along the circumference of the side wall, an inclined feeding pipe 334 with one end connected to the through connection port 3330 and the other end connected to the trapping filler box 334, and a feeding empty box 333 having a feeding opening and closing cover plate 3331 at the upper end;

[0051] The trapping packing box 330 is equipped with a weight sensor 335, and the bottom of the feeding box 333 is equipped with a sprinkling protrusion 3332, and the bottom of the sprinkling protrusion 3332 is equipped with a vibrator 3333.

[0052] Among them, the solar panel 121, the first hydraulic cylinder 22, the automatic opening and closing plate 320, the microprocessor 40, the first camera 41, the identification and counting module 42, the signal transmitting and receiving module 43, the battery pack 44, the power detection module 45, and the power switching module 46 all adopt existing technologies.

[0053] Example 2

[0054] This embodiment discloses a method for monitoring aquatic organism abundance, based on an aquatic organism abundance monitoring device from Embodiment 1, including the following steps:

[0055] S1. When the monitoring support frame 1 is not in use, each of the distributed support rods 10 is close together and in a folded state. When it is necessary to unfold the monitoring support frame 1, the sliding sleeves 111 are moved upward respectively, so that each of the cross folding frames 11 unfolds in the horizontal direction. At this time, the monitoring support frame 1 is in the unfolded state. The folding buckle 12, which is in the folded state, is unfolded and connected to the upper end of each distributed support rod 10, so that each solar panel 121 is laid flat and unfolded, and the solar energy is converted into electrical energy.

[0056] S2. Set the depth of the water to be monitored in advance, and control the first hydraulic cylinder 22 to start through the microprocessor 40. The first hydraulic cylinder 22 drives the sliding block 210 to move up and down in the vertical limiting slide groove 20, thereby adjusting the height of the connecting block 21 and the fishing monitoring box 30. When the preset depth is reached, the first hydraulic cylinder 22 is turned off.

[0057] S3. Open the release cover 331 and release bait into each baiting box 330. Add bait to the empty feeding box 333 by opening and closing the release cover 3331. After entering the empty feeding box 333, the bait falls through each through-connection port 3330 and the corresponding inclined feeding pipe 334, and is transported to the corresponding baiting box 330. Since the baiting boxes 330 are distributed at each fishing inlet 31, they can lure aquatic animals into the empty feeding box 333 through the fishing inlet 31, and force open each one-way valve 310 to enter the fishing monitoring box 30. The bait is then released into the empty feeding box 333. The bottom of the interior is equipped with a feeding protrusion 3332, which facilitates the bait to fall at each through-connection port 3330, preventing the bait from accumulating inside the empty feeding box 333. At this time, the first camera 41 takes pictures of the aquatic animals entering the fishing monitoring box 30 and transmits them to the identification and counting module 42. The identification and counting module 42 identifies and counts specific types of aquatic animals. Each fishing monitoring box 30 corresponds to a habitat, thereby monitoring the abundance of specific types of aquatic animals at each habitat. The signal is then sent to the external control center through the signal transmitter and receiver 43.

[0058] Example 3

[0059] The difference between this embodiment and Embodiment 1 is that:

[0060] like Figure 8As shown, the monitoring support frame 1 also includes a sliding folding frame 13. The sliding folding frame 13 is composed of four sliding folding rods 130 that correspond one-to-one with the distribution support rods 10. One end of the sliding folding rod 130 is connected to the corresponding sliding folding rod 130 through a sliding sleeve 111, and the other end is hinged to the side wall of the mounting plate 131. A second camera 132 is provided at the bottom of the distribution mounting plate 131.

[0061] The second camera 132 uses existing technology.

[0062] Example 4

[0063] The difference between this embodiment and Embodiment 2 is that:

[0064] When the sliding folding frame 13 is in use, the corresponding sliding sleeves 111 on each sliding folding rod 130 are slid down along the distribution support rod 10. At this time, each sliding folding rod 130 unfolds with each other, and the habitat of aquatic animals is monitored by the second camera 132. When the sliding folding frame 13 is finished to be used, the sliding sleeves 111 are pushed up along the corresponding distribution support rod 10 to fold the sliding folding frame 13.

[0065] Example 5

[0066] The difference between this embodiment and Embodiment 3 is that:

[0067] like Figure 2 , 3 As shown, the bottom end of the sub-folding buckle plate 120 located at the edge is provided with a connection port 122, and an elastic insertion rod 123 is provided through the side wall of the connection port 122. The upper end of each distribution support rod 10 is inserted into the connection port 122, and an insertion fixing hole 100 is provided on the side wall of the distribution support rod 10 at the position corresponding to the elastic insertion rod 123.

[0068] Example 6

[0069] The difference between this embodiment and embodiment 4 is that:

[0070] When the folding buckle 12 is connected to each of the distribution support rods 10, the elastic plug rod 123 is pulled outward to abut each of the distribution support rods 10 against the corresponding connection port 122. Then, the elastic plug rod 123 is released and inserted into the plug fixing hole 100 to fix the folding buckle 12 to each of the distribution support rods 10.

[0071] Example 7

[0072] The difference between this embodiment and embodiment 5 is that:

[0073] like Figure 4As shown, three buffer clamping plates 200 are respectively provided on the left and right sides of the vertical limiting slide groove 20. The buffer clamping plates 200 on the left and right sides of the vertical limiting slide groove 20 are paired and distributed opposite each other. Each buffer clamping plate 200 is connected to the inner wall of the vertical limiting slide groove 20 through the second hydraulic cylinder 201. Three insertion posts 202 are respectively provided on the side wall of the buffer clamping plate 200 and on the side opposite to the second hydraulic cylinder 201. Buffer insertion holes 203 are provided on the side wall of the sliding block 210 and at the corresponding positions of each insertion post 202. Each buffer clamping plate 200 is provided with an infrared detector 204.

[0074] The second hydraulic cylinder 201 and the infrared detector 204 adopt existing technologies.

[0075] Example 8

[0076] The difference between this embodiment and embodiment 6 is that:

[0077] When the height adjustment component 2 is used, the first hydraulic cylinder 22 is activated, which drives the sliding block 210 to move up and down within the vertical limiting groove 20, thereby adjusting the height of the connecting block 21 and the fishing monitoring box 30 to complete the fishing and abundance monitoring of aquatic animal species at different depths. When the sliding block 210 moves to the required height, the infrared detector 204 detects the signal and activates the two second hydraulic cylinders 201 at the corresponding height. The two relatively distributed second hydraulic cylinders 201 move closer to each other, causing the corresponding buffer clamping plate 200 to clamp the sliding block 210 and decompose the external force on the second hydraulic cylinder 201.

[0078] Example 9

[0079] The difference between this embodiment and embodiment 7 is that:

[0080] like Figure 6 , 7 As shown, the side wall of the one-way valve disc 310 is provided with an elastic anti-collision layer 311, and the elastic anti-collision layer 311 is a detachable structure. The automatic opening and closing plate 320 is provided with a filtrate opening 321, and a filtrate screen 322 is provided at the filtrate opening 321.

[0081] Example 10

[0082] The difference between this embodiment and embodiment 8 is that:

[0083] By setting an elastic anti-collision layer 311 to buffer the direct impact between aquatic animals and each one-way valve 310, and by setting a filter screen 322 on the automatic opening and closing plate 320, the water entering the fishing monitoring box 30 can be easily filtered out.

When the monitoring support frame (1) is not in use, each distribution support rod (10) is close to each other and in a folded state. When it is necessary to unfold the monitoring support frame (1), the sliding sleeve (111) is moved upward respectively, so that each cross folding frame (11) unfolds in the horizontal direction. At this time, the monitoring support frame (1) is in an unfolded state. The folding buckle plate (12) in the folded state is unfolded, and the folding buckle plate (12) is connected to the upper end of each distribution support rod (10), so that each solar panel (121) is laid out flat and converts solar energy into electrical energy. S2. Set the depth of the bottom to be monitored in advance, and start the first hydraulic cylinder (22) through the microprocessor (40). The first hydraulic cylinder (22) drives the sliding block (210) to move up and down in the vertical limit slide groove (20) to adjust the height of the connecting block (21) and the fishing monitoring box (30). When the preset depth is reached, the first hydraulic cylinder (22) is turned off. S3. Open the release cover (331) and release bait into each trap filling box (330). At this time, the bait will cause the aquatic animals in the area to enter the trap monitoring box (30) through the trap inlet (31) and push open each one-way valve (310). At this time, the aquatic animals entering the trap monitoring box (30) are photographed by the first camera (41) and transmitted to the identification and counting module (42). The identification and counting module (42) identifies and counts specific types of aquatic animals. Each trap monitoring box (30) corresponds to a habitat point, thereby monitoring the abundance of specific types of aquatic animals at each habitat point. The signal is sent to the external control center through the signal transmitter and receiver (43).
