Description

Technical Field

[0001] The present invention relates to the technical field of river biological monitoring, in particular to a Yellow River basin aquatic biodiversity monitoring system. Background Art

[0002] Monitoring aquatic biodiversity in the Yellow River Basin is a core foundation for ecological protection and restoration, playing an irreplaceable role in maintaining the basin's ecological balance. Among the current mainstream monitoring methods, devices using suspended balls carrying collection buckets are widely used, but they have significant technical limitations. This type of device lacks an intelligent timed recovery mechanism. In the high water temperature and high organic matter content of the Yellow River, samples are prone to decay after prolonged immersion, leading to DNA degradation and loss of morphological characteristics, directly impacting species identification accuracy. Furthermore, its single chamber structure and fixed-aperture water inlet design only capture pelagic fish and large aquatic plants, failing to capture key groups such as zooplankton and benthic invertebrates, resulting in a significant limitation in sample diversity. In addition, the Yellow River flows rapidly and has a high sediment content. The fixed structure of the existing device is easily eroded and displaced, and the sampling area deviates from the preset monitoring point, further reducing the representativeness of the sample and seriously restricting the accurate assessment and dynamic monitoring of the health status of the basin's aquatic ecosystem.

[0019] Reference Figures 1 to 12 This embodiment provides a Yellow River Basin aquatic biodiversity monitoring system, which includes a suspension unit 100 , including a buoy assembly 101 and a power supply assembly 102 disposed on the buoy assembly 101 .

[0020] The float assembly 101 is made of PE material and filled with helium or buoyancy materials such as polystyrene foam, which can ensure the buoyancy of the entire monitoring system and prevent it from sinking to the bottom of the river.

[0021] Furthermore, the power supply component 102 includes a solar panel and a mounting base. The solar panel is fixed above the buoy component 101 through the mounting base.

The collection bucket 201 and the cleaning assembly 202 are disposed at the bottom of the float assembly 101 , and the outer wall of the collection bucket 201 is in contact with the cleaning assembly 202 .

[0023] Among them, the collection bucket 201 is used to collect various samples in the river, such as mud, water plants, fish and other aquatic organisms. The plankton attached to the outer wall of the collection bucket 201 due to long-term immersion is mixed with river mud, and there is a risk of corrosion of the collection bucket 201. The cleaning component 202 is used to scrape off impurities on the outer wall of the collection bucket 201 to ensure the service life of the collection bucket 201.

[0024] The fixing unit 300 includes a driving box 301 and an anchor hook 302 . The driving box 301 is disposed at the bottom of the cleaning assembly 202 , and the anchor hook 302 is fixed to the driving group in the driving box 301 .

[0025] The driving group provided in the driving box 301 is a driving motor, a chain is wound around the driving motor, and the chain is fixed to the bottom of the riverbed through an anchor hook 302 to prevent the monitoring system from moving at will.

[0026] Specifically, the buoy assembly 101 includes a central buoy 101a and auxiliary buoys 101b arranged around the central buoy. The central buoy 101a and the auxiliary buoys 101b are fixed by a cross 101c. The central buoy 101a is preferably a hollow buoy, which can be square, cylindrical or other shapes. This embodiment preferably adopts a cylindrical shape. Similarly, the auxiliary buoys 101b are also cylindrical structures. Preferably, four groups are provided, which are respectively arranged around the central buoy 101a. The diameter of the central buoy 101a is larger than that of the auxiliary buoy 101b, so that its center of gravity is concentrated at the center of the central buoy 101a.

[0027] The power supply assembly 102 is fixedly arranged on the top of the central buoy 101a and the auxiliary buoy 101b. The power supply assembly 102 includes a solar panel and a mounting base. The solar panel is fixed on the top of the buoy assembly 101 through the mounting base. The exterior is waterproofed to prevent strong wind and river water from splashing onto the solar panel and causing a short circuit. Preferably, five groups of solar panels are arranged correspondingly on the central buoy 101a and the surrounding auxiliary buoys 101b.

[0028] A lower probe frame 101d is fixedly connected to the cross 101c. The lower probe frame 101d includes symmetrically arranged probe rods 101d-1. The top probe rods 101d-1 are fixedly connected by a cross bar 101d-2.

[0029] The top of the symmetrically arranged probe rod 101d-1 is fixedly connected to a mounting flange 101d-1a, and the mounting flange 101d-1a is fixed to the first mounting plate 101a-1 fixed to the outer wall of the central buoy 101a. The mounting flange 101d-1a and the first mounting plate 101a-1 are detachably fixed by the cooperation of bolts and nuts. A first motor 101a-2 is fixed in the central buoy 101a, and a screw rod 101a-3 is fixedly connected to the output shaft of the first motor 101a-2, and the screw rod 101a-3 slides through the cross bar 101d-2.

[0030] Among them, the contact part between the screw rod 101a-3 and the central buoy 101a adopts a shaft sealing device to isolate the internal space of the central buoy 101a from the outside world and prevent river water from entering the central buoy 101a.

[0031] The bottom end of the probe rod 101d-1 is fixedly connected to a ring plate 101d-1b, and the outer side wall of the ring plate 101d-1b is fixedly connected to a second mounting plate 101d-1b1.

[0032] The inner walls at both ends of the ring plate 101d-1b are symmetrically fixed with mounting blocks 101d-1b2, and the cleaning component 202 is slidably set in the mounting blocks 101d-1b2, wherein the ring plate 101d-1b is a circular ring structure, and there is a displacement gap between the ring plates 101d-1b on both sides for the cleaning component 202 to move to both sides.

[0033] The cleaning assembly 202 includes an annular pressure plate 202a and first slide bars 202b fixed at both ends. The first slide bars 202b are slidably engaged in the mounting blocks 101d-1b2.

[0034] A first spring T1 is fixedly connected between the first spring plate B1 on the mounting block 101d - 1b2 and the second spring plate B2 fixed to the end of the first sliding rod 202b.

[0035] In the initial state, the annular pressure plates 202a on both sides are assembled to form a circular cleaning ring, and the inner wall of the circular cleaning ring is a conical structure that is easy to scrape off impurities.

[0036] During use, when the collection bucket 201 moves up and down and adjusts the collection height, the annular pressing plate 202a can remove impurities such as floating grass and gravel attached to the outer wall of the collection bucket 201.

[0037] The collection bucket 201 includes a docking frame 201a and a collection box 201b fixed at the bottom thereof. The top opening of the collection box 201b is also movably provided with a sealing component 201c.

[0038] Specifically, both ends of the docking frame 201a are slidably sleeved on the outside of the probe rod 101d-1, and a connecting sleeve 201a-1 is fixedly connected to the middle of the docking frame 201a, and the connecting sleeve 201a-1 is threadedly sleeved on the outside of the screw rod 101a-3. During use, as the screw rod 101a-3 rotates forward and backward, the collection bucket 201 connected to it through the connecting sleeve 201a-1 is restricted by the circumferential direction of the probe rod 101d-1. The collection bucket 201 can move up and down. As the collection bucket 201 moves, impurities such as floating grass and gravel attached to its outer wall will be scraped off by the annular pressure plate 202a. The first spring T1 applies adjustable pressure to the annular pressure plate 202a to ensure that the annular pressure plate 202a is always pressed against the outside of the collection bucket 201.

[0039] Furthermore, the collection box 201b includes a ring interface 201b-1 and a connection cover 201b-2 fixed at the bottom thereof, and a box body 201b-3 is detachably fixed at the bottom of the connection cover 201b-2.

[0040] Openings 201b-2a are symmetrically provided in the connecting cover 201b-2, and the mud, water plants, fish and other aquatic organisms that need to be collected enter the box body 201b-3 through the openings 201b-2a. An inclined guide ring 201b-2b is sealed and connected to the box body 201b-3 at the corresponding position of the opening 201b-2a, and a separating ring 201b-2c is coaxially fixedly connected to the bottom end of the inclined guide ring 201b-2b; a protective gap X is formed between the separating ring 201b-2c and the box body 201b-3, wherein the inclined guide ring 201b-2b can guide the sample into the box body 201b-3.

[0041] The bottom end of the annular interface 201b-1 is coaxially fixedly connected with a sealing sleeve 201b-1a, and the sealing sleeve 201b-1a is slidably sleeved on the outside of the screw rod 101a-3.

[0042] A partition plate 201b-3a is sealed in the collection box 201b, and the sealing sleeve 201b-1a is sealed and inserted into the partition plate 201b-3a. The partition plate 201b-3a divides the internal chamber of the collection box 201b into a collection chamber S1 and an installation chamber S2. The collection chamber S1 is connected to the protective gap X.

[0043] During use, the sealing sleeve 201b-1a isolates the collection chamber S1 of the box 201b-3 from the external space. After the sample enters the collection chamber S1 from the opening 201b-2a, the gravel sample is deposited on the partition plate 201b-3a, and fish and other organisms swim back and forth in the protective gap X. The separation ring 201b-2c can prevent the fish from swimming back to the opening 201b-2a, preventing the subsequent entry of sharp gravel from damaging the fish sample.

[0044] An exchange port 201b-3b is provided on the side wall of the collection box 201b, and a guide sleeve 201b-3c is symmetrically fixedly connected to the inner wall of the collection box 201b on both sides of the exchange port 201b-3b. An anti-escape plate 201b-4 is slidingly provided inside the guide sleeve 201b-3c, and a first drive cylinder 201b-5 is symmetrically fixed to the bottom end of the cavity wall of the installation chamber S2.

[0045] Specifically, the anti-escape plate 201b-4 includes symmetrically arranged limit blocks 201b-4a, a second sliding rod 201b-4b is fixedly connected between the top limit block 201b-4a and the bottom limit block 201b-4a, and a sealing plate 201b-4c is connected between the top limit blocks 201b-4a, and the sealing plate 201b-4c seals the exchange port 201b-3b.

[0046] A second spring T2 is connected to the outer cover of the second sliding rod 201b-4b between the bottom limiting block 201b-4a and the guide sliding sleeve 201b-3c.

[0047] During use, in the initial state, the second spring T2 pushes the bottom limit block 201b-4a downward, driving the sealing plate 201b-4c to seal the exchange port 201b-3b.

[0048] A sieve plate 201b-3a1 is provided on the top of the partition plate 201b-3a, and the sieve plate 201b-3a1 is fixed to the partition plate 201b-3a by a third spring T3. Several groups of sieve holes K are opened on the sieve plate 201b-3a1, and the sieve holes K can filter gravel with smaller particle size into the collection chamber S1 below the sieve plate 201b-3a1.

The base plate 201c-1a and the internal component 201c-1c can move in the opening 201b-2a. The base plate 201c-1a and the side sealing plate 201c-1b can jointly seal the opening 201b-2a to prevent the sample from escaping.

[0052] The built-in parts 201c-1c on both sides are symmetrically provided with embedded grooves 201c-1c1, and the intercepting parts 201c-2 are slidably set in the embedded grooves 201c-1c1. The intercepting parts 201c-2 are used to intercept excess aquatic plants to prevent the openings 201b-2a from being blocked by aquatic plants.

[0053] The connecting sleeve 201a-1 is slidably inserted between the internal components 201c-1c on both sides, and the sealing sleeve 201b-1a is slidably inserted into the base plate 201c-1a.

[0055] During use, the first drive cylinder 201b-5 is started, driving the guide rod 201c-1d to move upward, and the sieve plate 201b-3a1 is pushed upward. During this process, the sieve plate 201b-3a1 pushes the bottom limit block 201b-4a from bottom to top, and the bottom limit block 201b-4a drives the sealing plate 201b-4c to move upward, the exchange port 201b-3b is opened, and some sand and gravel are pushed out from the exchange port 201b-3b. At the same time, if there are fish in the collection box 201b, the fish can also swim out of the exchange port 201b-3b to prevent the fish from dying due to lack of food for a long time.

[0056] The intercepting member 201c-2 includes an arc-shaped bottom plate 201c-2a, the inner arc side wall of the arc-shaped bottom plate 201c-2a is symmetrically fixed with a connecting tooth plate 201c-2b, the outer arc edge of the arc-shaped bottom plate 201c-2a is vertically fixed with a side sealing plate 201c-2c, and the side of the arc-shaped bottom plate 201c-2a close to the side sealing plate 201c-2c is equidistantly fixed with a hook column 201c-2d, which is used to hook aquatic plants.

[0057] A control groove 201c-1c2 is symmetrically opened on one side of the inner part 201c-1c near the outer wall of the connecting sleeve 201a-1.

As the intercepting piece 201c-2 moves back and forth, the side sealing plate 201c-2c cooperates with the hook column 201c-2d to push the aquatic plants into the embedded groove 201c-1c1, and the cutting blades 201c-1c4 can cut the aquatic plants. The cut aquatic plants will fall naturally as the intercepting piece 201c-2 is pushed out of the embedded groove 201c-1c1.

[0059] The outer wall of the connecting sleeve 201a-1 is symmetrically connected with a first protrusion 201a-1a. The first protrusion 201a-1a is provided with a first tooth connection groove 201a-1b. The first tooth connection groove 201a-1b is meshed with the gear 201c-1c3.

[0060] The annular interface 201b-1 is symmetrically connected to a second protrusion 201b-1b. The second protrusion 201b-1b is located at the bottom of the first protrusion 201a-1a. The second protrusion 201b-1b is provided with a second tooth connection groove 201b-1c. The second tooth connection groove 201b-1c is engaged with the gear 201c-1c3.

[0061] During use, when the base plate 201c-1a and the edge sealing plate 201c-1b seal the opening 201b-2a, the collection box 201b is in sample collection mode. At this time, the sealing plate 201b-4c blocks the exchange port 201b-3b, and the internal space of the collection box 201b exchanges substances with the external river water through the air outlet 201b-2d, thereby preventing the fish that may be collected inside from dying in a short period of time.

[0062] When the internal sample needs to be updated, the first drive cylinder 201b-5 is started, and the base plate 201c-1a is pushed upward through the guide rod 201c-1d. At this time, the opening 201b-2a is opened. During this process, the rising first tooth groove 201a-1b and the second tooth groove 201b-1c are engaged with the gear 201c-1c3 at the same time, driving it to rotate clockwise, and the rotating gear 201c-1c3 will push the intercepting member 201c-2 outward through the connecting tooth plate 201c-2b, so that the hook column 201c-2d extends outward, making it easier to hook aquatic plants.
