Description

Technical Field

[0001] This invention relates to the field of biological sampling technology, specifically to a biodiversity monitoring and sampling device for protected areas. Background Technology

[0002] A watershed is the catchment area of ​​a river enclosed by a watershed line. Plankton refers to drifting organisms that live in water but lack effective mobility. It includes phytoplankton and zooplankton. Some plankton have the ability to swim, but their movement speed is often slower than the ocean currents they are in, thus preventing them from moving effectively and flexibly in the water. Plankton, among the organisms in oceans, lakes, and rivers, have no or very weak mobility and therefore cannot move against the current, but instead float on the surface. These organisms are collectively called plankton. Plankton plays an important role in the food chain of aquatic ecosystems. Plankton are economically important aquatic animals. Besides affecting fisheries, plankton also has several practical significances, such as serving as indicator species for ocean currents, which helps in exploring the direction of ocean currents. Therefore, during watershed surveys, plankton are often collected for various tests to infer the ecological environment of the watershed.

[0003] Existing technologies typically employ sampling devices to sample water bodies containing plankton. However, both sampling and sample removal require manual or electric operation. The former necessitates manual operation of the handheld device (such as a water sampler or plankton net) at a designated location for each sampling. For monitoring tasks requiring coverage of large water areas (such as lakes or rivers) or multiple depth gradients (such as different water layers), this is time-consuming and labor-intensive, making it difficult to collect a sufficient number of samples in a short time, thus affecting the timeliness of monitoring. The latter involves electric equipment whose core components, such as circuits, batteries, and sensors, rely on sealed structures (such as sealing rings or waterproof adhesives) to isolate them from the water. During long-term underwater operations or under high pressure in deep water environments, these seals are prone to aging and deformation, leading to water leakage, short circuits, and equipment damage.

[0004] For example, the invention patent with patent application number 202411280466.1 discloses a watershed biodiversity monitoring sampling device. The patent describes that when sampling is required, the controller controls the electric telescopic rod to retract, the bottle stopper and the sampling bottle separate, and the water sample in the watershed enters from the top of the sampling bottle. After sampling is completed, the controller controls the electric telescopic rod to extend, so that the bottle stopper and the sampling bottle are locked together to seal the sampling bottle. That is, the electric telescopic rod is in contact with the water body during sampling, which will cause damage to the electric telescopic rod over a long period of time. The prior art represented by this patent urgently needs to be addressed. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a biodiversity monitoring and sampling device for protected areas, which solves the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a biodiversity monitoring and sampling device for a protected area, comprising a support frame, a rotating roller rotatably inserted into the support frame, and multiple equidistantly distributed support rods fixed to the end of the rotating roller. Each support rod has a sampling shell at its other end. An isolation cover is fixedly connected to the inner wall of the sampling shell, forming a sampling chamber between the isolation cover and the sampling shell. An elastic component is provided inside the isolation cover, and two sealing rods are provided on the elastic component. Two symmetrically distributed through holes are opened on the surface of the sampling shell, communicating with the sampling chamber. The ends of the sealing rods movably penetrate the isolation cover and are inserted into the through holes. A drainage hole is opened at the center of the sampling chamber. A hollow rotating shaft is fixedly connected to the side wall of the sampling shell, communicating with the drainage hole. A docking component one is fixedly connected to the other end of the rotating shaft, and a docking component two is provided on the support frame. When docking component one and docking component two are aligned, the sample inside the sampling chamber is discharged.

[0009] Preferably, the docking assembly includes a docking tube fixedly connected to the rotating shaft, a retaining ring fixed inside the docking tube, and a positioning block. A sealing spring is fixedly connected to one end of the positioning block, and a magnetic block for sealing the retaining ring is fixedly connected to one end of the sealing spring.

[0010] Preferably, the docking assembly 2 includes a docking pipe 2 fixedly connected to the drain pipe, a retaining ring 2 fixed inside the docking pipe 2, and a positioning block 2. A sealing spring 2 is fixedly connected to the end of the positioning block 2, and the end of the sealing spring 2 passes through the retaining ring 2 and is fixedly connected to a magnetic block 2 for sealing the retaining ring 2.

[0011] Preferably, the rotating shaft is rotatably mounted on the support rod via a bearing, a gear is fixedly sleeved on the rotating shaft, a torsion spring is fixedly connected between the gear and the support rod, and a driving component for driving the gear to rotate is provided on the bracket.

[0012] Preferably, the driving component includes a positioning rod fixed to the side wall of the bracket and a toothed ring fixed to the end of the positioning rod, the toothed ring being able to mesh with the gear from above.

[0013] Preferably, the elastic component includes a guide rail fixed inside the isolation cover, a slider that can be linearly displaced and slidably disposed on the guide rail, two symmetrically distributed connecting rods rotatably connected to the slider, the other end of the connecting rods being rotatably connected to a sealing rod, and a return spring being fixedly connected between the slider and the isolation cover.

[0016] Preferably, the device also includes a belt conveyor and a sampling bottle placed on the belt conveyor. During sampling, the bottle opening corresponds to the opening of the drain pipe. The belt of the belt conveyor is provided with equidistantly distributed limiting grooves.

[0017] (III) Beneficial Effects

[0018] This invention provides a biodiversity monitoring and sampling device for protected areas, which has the following beneficial effects:

[0019] 1. In this invention, when the sampling shell enters the water body under the drive, the water pressure causes the sealing rod to detach from the through hole, allowing water containing plankton to enter the sampling chamber. When the sampling shell rotates to the position where it is separated from the water, the sealing rod resets to seal the through hole. When the sampling shell rotates to the drainage position, i.e., docking component one and docking component two are connected, the water is introduced into the drain pipe to achieve the purpose of discharge. The entire process does not require manual sampling and does not involve any electric equipment underwater, thus reducing labor intensity, improving sampling efficiency, and extending the product's service life.

[0020] 2. In this invention, by setting gears and gear rings, when the two mesh, the sampling shell can be rotated around the axis of rotation. Shaking the sampling shell can break the layered state and make the various components in the sample (such as biological individuals, chemical substances, particles, etc.) remixed evenly, avoiding the sampling bottle only collecting "local samples" of a certain layer, which would lead to distorted test results.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Please see Figures 1 to 5This invention provides a technical solution: a biodiversity monitoring and sampling device for a protected area, comprising a support 1, a rotating roller 2 rotatably inserted on the support 1, and multiple equidistantly distributed support rods 3 fixed to the end of the rotating roller 2. A motor 28 is fixedly installed on the support 1, and the motor 28 is fixedly connected to the rotating roller 2 via a coupling. The motor 28 can be encoded by an encoder to control its stroke. When docking component one and docking component two are docked, the motor 28 needs to stop. Sampling shells 4 are provided at the other end of each support rod 3. An isolation cover 5 is fixedly connected to the inner wall of the sampling shell 4, forming a sampling chamber 6 between the isolation cover 5 and the sampling shell 4. An elastic component is installed inside the isolation cover 5, and two sealing rods 7 are installed on the elastic component. Two symmetrically distributed through holes 401 are opened on the surface of the sampling shell 4. The through holes 401 are connected to the sampling chamber 6. The end of the sealing rod 7 can be moved through the isolation cover 5 and inserted into the through hole 401. A drainage hole 402 is opened at the center of the sampling chamber 6. A hollow rotating shaft 12 is fixedly connected to the side wall of the sampling shell 4. The rotating shaft 12 is connected to the drainage hole 402. The other end of the rotating shaft 12 is fixedly connected to a docking component one. A docking component two is installed on the bracket 1. When the docking component one and docking component two are aligned, the sample inside the sampling chamber 6 is discharged.

[0034] Motor 28 drives the rotating roller 2 to rotate, which in turn drives each support rod 3 and the sampling shell 4 to rotate around the rotating roller 2; that is, motor 28 drives the sampling shell 4 to rotate around the rotating roller 2. Figure 1 As shown, rotating clockwise, when the sampling shell 4 enters the water body under the drive, due to the water pressure, the water body forces the sealing rod 7 to move linearly, causing the end of the sealing rod 7 to detach from the through hole 401. At this time, water containing plankton enters the sampling chamber 6. When the sampling shell 4 rotates to the position where it is separated from the water body, the sealing rod 7 resets under the action of the elastic component and re-seals the through hole 401. When the sampling shell 4 rotates to the drainage position (i.e., as shown in the diagram), the sealing rod 7 re-seals the through hole 401. Figure 5 (As shown in the image), at this time, docking component one and docking component two are connected, and the water inside the sampling chamber 6 is introduced into the drain pipe 15 to achieve the purpose of discharge; the whole process does not require manual sampling and no electric equipment is set underwater, which reduces the intensity of manual labor, improves sampling efficiency, and also improves the service life of the product.

[0035] This device can be set up in the watershed to be sampled, either on the bank or on a boat.

[0036] For areas such as shallow waters, riverbanks, and lake shores, the support frame 1 is fixed to the shore (secured by anchor bolts or counterweights), allowing the sampling arm to be extended directly into the water. Sampling of near-shore water can be completed without wading, avoiding the safety risks of manual wading.

[0037] For open water areas (such as the center of a lake or the main channel of a river), deep water areas, or flowing water bodies (such as rapids), bracket 1 is installed on a sampling vessel or speedboat, which can move with the vessel to any location, covering areas that are difficult to reach from the shore. For example, gradient sampling from the upper to the lower reaches of a river, and comparative sampling of different points in the center of a lake, can achieve systematic data collection of "multiple points and a large area" by moving the vessel, solving the problem of limited sampling range in traditional methods.

[0038] See Figure 4 The elastic component includes a guide rail 10 fixed inside the isolation cover 5, a slider 9 that can be linearly displaced and slidably disposed on the guide rail 10, two symmetrically distributed connecting rods 8 rotatably connected to the slider 9, the other end of the connecting rods 8 being rotatably connected to the sealing rod 7, and a return spring 11 fixedly connected between the slider 9 and the isolation cover 5.

[0039] The following describes the principle of the elastic component's operation. When the water compresses the sealing rod 7, causing it to move linearly, the end of the sealing rod 7 disengages from the through hole 401. The sealing rod 7 then pushes the slider 9 to slide on the guide rail 10 via the connecting rod 8. At this time, the slider 9 slides towards the return spring 11, causing the return spring 11 to be compressed and store elastic potential energy. When the sampling shell 4 is removed from underwater, the return spring 11 releases its elastic force, pushing the return spring 11 to move in the opposite direction. The slider 9, via the connecting rod 8, drives the end of the sealing rod 7 to be reinserted into the through hole 401, achieving a seal.

[0040] See Figure 4 A retaining ring 31 is fixedly connected to the sealing rod 7, and the retaining ring 31 is located inside the sampling chamber 6. The purpose of setting the retaining ring 31 is to limit the linear displacement of the sealing rod 7, that is, to prevent the sealing rod 7 from completely entering the inner side of the isolation cover 5. Sealing rubber rings are set at the contact positions between the through hole 401 of the isolation cover 5 and the sampling shell 4 and the sealing rod 7, so as to improve the sealing and waterproofing capabilities.

[0041] See Figure 8 The docking assembly includes a docking tube 16 fixedly connected to the rotating shaft 12, a retaining ring 17 fixed inside the docking tube 16, and a positioning block 18. A sealing spring 19 is fixedly connected to the end of the positioning block 18. The end of the sealing spring 19 passes through the retaining ring 17 and is fixedly connected to a magnetic block 20 for sealing the retaining ring 17.

[0042] See Figure 8 The second docking component includes a second docking pipe 21 fixedly connected to the drain pipe 15, a second retaining ring 25 fixed inside the second docking pipe 21, and a second positioning block 22. A second sealing spring 23 is fixedly connected to the end of the second positioning block 22. The end of the second sealing spring 23 passes through the second retaining ring 25 and is fixedly connected to a second magnetic block 24 for sealing the second retaining ring 25. The magnetic poles of the first magnetic block 20 and the second magnetic block 24 are opposite on opposite sides, and they attract each other when they are close to each other.

[0043] The working principle of docking components one and two during docking is explained in detail below: When docking pipe one 16 moves to the position of docking pipe two 21, the two are in a connected state. At this time, magnetic block one 20 and magnetic block two 24 attract each other. At this time, the retaining ring one 17 is not closed by magnetic block one 20 and is in a free state; similarly, the retaining ring two 25 is not closed by magnetic block two 24 and is in a free state; and sealing spring one 19 and sealing spring two 23 are both in a stretched state. At this time, the water inside the sampling chamber 6 is discharged into docking pipe one 16 through the drain hole 402 and the rotating shaft 12 due to gravity, and then through docking pipe two 21, and finally discharged through the drain pipe 15. This method achieves the purpose of automatic sample discharge without manual operation or electric equipment, reducing labor intensity and economic costs.

[0044] When docking component one and docking component two are misaligned, that is, when they are not connected, magnetic block one 20 seals retaining ring one 17 under the traction of sealing spring one 19 to prevent water leakage; magnetic block two 24 seals retaining ring two 25 under the action of sealing spring two 23.

[0045] See Figure 6 and Figure 7 The rotating shaft 12 is rotatably mounted on the support rod 3 via a bearing. A gear 14 is fixedly sleeved on the rotating shaft 12. A torsion spring 13 is fixedly connected between the gear 14 and the support rod 3. A drive component for driving the gear 14 to rotate is provided on the bracket 1.

[0046] See Figure 5 The driving component includes a positioning rod 27 fixed to the side wall of the bracket 1 and a toothed ring 26 fixed to the end of the positioning rod 27. The toothed ring 26 can mesh with the gear 14 from above.

[0047] Many samples to be tested (such as plankton in the water) may stratify or settle due to gravity when in the sampling shell 4 (e.g., light plankton float to the surface, microorganisms gather in a certain area); repeated sampling can lead to excessive differences between samples.

[0048] Plankton (especially flagellated algae and small crustacean larvae) may adhere to the inner wall or corners of the sampling device due to surface tension, static electricity, or mucus secretion.

[0049] To address the aforementioned issues, in this application, when the motor 28 drives the sampling shell 4 to rotate around the rotating roller 2, the gear 14 needs to mesh with the gear ring 26 during the movement. When the two mesh, the sampling shell 4 is driven to rotate around the rotating shaft 12. When the gear 14 disengages from the gear ring 26, the torsion spring 13 releases torque to reset the gear 14 and the sampling shell 4. The shaking of the sampling shell 4 during the above process can break the layered state and allow the various components in the sample (such as biological individuals, chemical substances, particles, etc.) to be remixed evenly, avoiding the sampling bottle 30 from collecting only a "local sample" of a certain layer, which would lead to distorted test results.

[0050] See Figure 9 and Figure 10 It also includes a belt conveyor 29 and a sampling bottle 30 placed on the belt conveyor 29. When sampling, the bottle mouth of the sampling bottle 30 corresponds to the position of the pipe mouth of the drain pipe 15. The belt of the belt conveyor 29 is provided with equidistantly distributed limiting grooves 2901.

[0051] The belt conveyor 29 is horizontally positioned below the drain pipe 15. In this application, the sampling bottle 30 can be used to directly collect the liquid discharged from the drain pipe 15; alternatively, the belt conveyor 29 can be set up to achieve continuous filling, with each sampling bottle 30 placed inside a limiting groove 2901. The limiting groove 2901 serves to limit the flow and prevent the sampling bottle 30 from tipping over during transport.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
