Description

Technical Field

[0001] This invention relates to the field of sampling device technology, specifically a suspended natural precipitation sampling device for monitoring changes in marine data. Background Technology

[0002] Monitoring changes in marine data is a crucial tool for marine scientific research and marine environmental protection. Data on the chemical composition, pH, and pollutant content of natural precipitation are key to analyzing climate change, ocean acidification, and pollutant migration. Traditional marine precipitation sampling devices are mostly fixed or buoy-based, but due to the complex marine environment, they often face problems such as seawater splashing, seabird contamination, and debris blockage, affecting the accuracy and continuity of sampling. In the prior art, Chinese Patent No. CN211786194U discloses a precipitation sampling device for marine meteorological monitoring, which includes a base, a water collection hopper, a storage tank, and a stratified sampling valve. This device uses a filter screen and filter cover to initially filter debris such as fallen leaves and sand, and utilizes a silicone membrane to prevent evaporation and contamination.

[0003] However, this device is a fixed structure, suitable for use on shore or fixed platforms, making it difficult to conduct long-term, automated precipitation monitoring in open sea areas. Furthermore, its filtration structure is relatively simple, making it ineffective against marine-specific pollutants such as seabird droppings and seaweed, and it lacks an automatic cleaning mechanism, which can easily lead to filter clogging with prolonged use, affecting sampling efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a suspended natural precipitation sampling device for monitoring changes in marine data, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a suspended natural precipitation sampling device for monitoring changes in marine data, comprising a buoy, a support plate fixedly connected to the top of the buoy, a fixed frame fixedly connected to the top of the support plate, a fixed cylinder fixedly connected to the top of the fixed frame, a rotating cylinder rotatably connected inside the fixed cylinder, a reciprocating threaded rod provided inside the rotating cylinder, a threaded ring fixedly connected to the top of the fixed cylinder, a support ring rotatably connected to the top of the threaded ring, a plurality of lower support rods fixedly connected to the top of the support ring, a support cylinder fixedly connected to one end of each of the plurality of lower support rods, a liquid storage tank threadedly connected inside each of the plurality of support cylinders, an inner liquid accumulation hopper provided inside each of the plurality of support cylinders, an outer liquid accumulation hopper fixedly connected to the outside of each of the plurality of inner liquid accumulation hoppers, an annular groove formed between the inner liquid accumulation hopper and the outer liquid accumulation hopper, and the support cylinder being adapted to the annular groove.

[0006] Preferably, a cover plate is fixedly connected to the top of the inner liquid hopper, and a water guide cover is fixedly connected to the top of the cover plate. Water passage grooves are provided on both sides of the cover plate. The water passage grooves connect the outer liquid hopper and the inner liquid hopper, so that the rainwater accumulated inside the outer liquid hopper passes through the water passage grooves and enters the inner liquid hopper for collection.

[0007] Preferably, a support cavity is fixedly connected inside the inner liquid hopper, a filter screen is fixedly connected inside the support cavity, an inner support nozzle is fixedly connected to the top of the liquid storage tank, the inner support nozzle is adapted to the inside of the inner liquid hopper, and a handle is fixedly connected to the bottom of the liquid storage tank. By holding the handle, the liquid storage tank can be rotated, allowing the liquid storage tank to be installed and disassembled inside the support cylinder.

[0008] Preferably, a screening bucket is slidably connected inside the outer liquid collection hopper, the screening bucket is adapted to the inner wall of the outer liquid collection hopper, a pull plate is fixedly connected to the top of the screening bucket, the water guide cover is arched, the pull plate is in contact with the top of the water guide cover, so that the pull plate drives the screening bucket to move up and down, and the screening bucket pushes out the debris that falls into the outer liquid collection hopper.

[0009] Preferably, each of the multiple external liquid collection hoppers is fixedly connected to one side with a connecting rod, the top of the support plate is fixedly connected to a waterproof cover, the top of the waterproof cover is rotatably connected to a rotating frame, the multiple connecting rods are fixedly connected to the inner wall of the rotating frame, and the outer side of the rotating frame is fixedly connected to multiple wind buckets. The multiple wind buckets are moved by the sea breeze, thereby driving the rotating frame to rotate.

[0010] Preferably, the rotating cylinder has limit plates fixedly connected to both sides, and the reciprocating threaded rod has limit grooves on both sides. The two limit plates are slidably connected to the two limit grooves and are adapted to the two limit grooves. The reciprocating threaded rod passes through the threaded ring and is threadedly connected to the threaded ring, so that the threaded ring limits the reciprocating threaded rod, thereby allowing the reciprocating threaded rod to move up and down when rotating.

[0011] Preferably, the support ring has integrally formed limit blocks on both sides inside. The two limit blocks are slidably connected to the two limit grooves and are adapted to the two limit grooves. The support ring limits the limit grooves through the two limit blocks, thereby driving the reciprocating threaded rod to rotate.

[0012] Preferably, a circular plate is fixedly connected to the top of the reciprocating threaded rod, and multiple upper support rods are fixedly connected to the top of the circular plate. The other ends of the multiple upper support rods are respectively fixedly connected to multiple pull plates. A telescopic cover is fixedly connected between the circular plate and the support ring.

[0013] Preferably, a round rod is fixedly connected to the top of the round plate, a platform is fixedly connected to the top of the round rod, a reflective strip is fixedly connected to the top of the platform, a top plate is fixedly connected to the top of the reflective strip, and a flagpole is fixedly connected to the outer side of the top plate. Multiple flagpoles are each fixedly connected to one end with a colored flag. The round rod drives the platform to rotate, and the platform's rotation causes the reflective strip and top plate to rotate. The reflective strip is coated with reflective paint, providing multi-angle reflection when illuminated, thus startling seabirds. The top plate also causes multiple flagpoles and colored flags to rotate, thereby causing multiple colored flags to flutter and scare away the seabirds.

[0014] Preferably, the buoy is fixedly connected to both sides with buckles, and the bottom of the waterproof cover has multiple drainage holes, so that the upper part of the waterproof cover blocks the waves and prevents seawater from contaminating the sample, and the drainage holes at the bottom drain the accumulated water.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This application features a water guide cover and a water channel at the top of the inner hopper. Rainwater can be guided along the water guide cover into the outer hopper, and after it is full, it enters the inner hopper through the water channel, avoiding splashing caused by direct falling in and improving rainwater collection efficiency. The double-layer structure of the outer and inner hoppers, combined with the matching design of the annular groove and support cylinder, effectively separates rainwater from impurities, preventing impurities from entering the sampling area and ensuring the purity of the precipitation samples. The storage tank and support cylinder are connected by threads and are equipped with handles for easy disassembly and installation, facilitating sample collection or replacement of sampling containers by sampling personnel and improving operational convenience.

[0016] 2. This application utilizes a dual filtration structure of a sieve hopper and a filter screen to effectively intercept larger impurities such as fallen leaves, bird droppings, and seaweed, preventing them from entering the storage tank and contaminating the samples. Simultaneously, the sieve hopper can be raised and lowered for cleaning, reducing daily maintenance difficulty. The linkage design of the wind hopper, rotating frame, and connecting rod allows natural wind power to drive the rotation of the outer liquid collection hopper. Combined with a threaded ring, reciprocating threaded rod, and limiting structure, this enables periodic raising and lowering of the sieve hopper for cleaning, resulting in a high degree of automation and requiring no additional energy.

[0017] 3. This application enables the platform to rotate, which in turn causes the reflective strips to rotate the top plate. As the top plate rotates, it causes multiple flagpoles to rotate, thereby causing multiple flagpoles to flutter. The multiple flags are all brightly colored, which is easy to scare away seabirds. At the same time, the rotating frame is a long, twisted strip with a reflective paint coating. When sunlight shines on it, the reflection shines outwards, which frightens seabirds. During the rotation, it produces a reflective and fluttering effect, which can effectively drive away seabirds and reduce the contamination of samples by bird droppings.

[0018] 4. This application uses a cable and a locking device to allow the ship to send the buoy to the monitoring position. After the buoy is pushed off the ship, it floats on the sea surface. Depending on the actual situation, the cable is tied to a fixed stake or the ship to collect samples of marine rainfall. The ship is dispatched periodically to collect the samples. By setting up the buoy and locking device, the entire device can be anchored at the marine monitoring point, enabling long-term and stable collection of natural precipitation, avoiding device drift caused by wind, waves or ocean currents, and ensuring the accuracy of the sampling point.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: Figures 1-17As shown, this invention provides a technical solution for a suspended natural precipitation sampling device for monitoring changes in marine data. The device includes a buoy 1, a support plate 2 fixedly connected to the top of the buoy 1, a fixing frame 3 fixedly connected to the top of the support plate 2, a fixing cylinder 4 fixedly connected to the top of the fixing frame 3, a rotating cylinder 5 rotatably connected inside the fixing cylinder 4, a reciprocating threaded rod 6 inside the rotating cylinder 5, a threaded ring 28 fixedly connected to the top of the fixing cylinder 4, a support ring 8 rotatably connected to the top of the threaded ring 28, multiple lower support rods 9 fixedly connected to the top of the support ring 8, a support cylinder 10 fixedly connected to one end of each of the multiple lower support rods 9, and a liquid storage tank 11 threadedly connected inside each of the multiple support cylinders 10. Multiple support cylinders 10 are each equipped with an inner liquid collection hopper 12. An outer liquid collection hopper 13 is fixedly connected to the outer side of each inner liquid collection hopper 12. An annular groove 20 is formed between the inner and outer liquid collection hoppers 12 and 13. The support cylinder 10 is adapted to fit the annular groove 20. A cover plate 14 is fixedly connected to the top of the inner liquid collection hopper 12, and a water guide cover 15 is fixedly connected to the top of the cover plate 14. Water passage grooves 17 are formed on both sides of the cover plate 14, connecting the outer and inner liquid collection hoppers 13. This allows rainwater accumulated inside the outer liquid collection hopper 13 to pass through the water passage grooves 17 and enter the inner liquid collection hopper 12 for collection. A support cavity 18 is fixedly connected inside the inner liquid collection hopper 12. A filter screen 19 is fixedly connected. An inner support nozzle 21 is fixedly connected to the top of the storage tank 11, and the inner support nozzle 21 is adapted to the inside of the inner liquid collection hopper 12. A handle 22 is fixedly connected to the bottom of the storage tank 11. By holding the handle 22, the storage tank 11 is rotated, allowing it to be installed and disassembled inside the support cylinder 10. A sliding hopper 16 is slidably connected inside the outer liquid collection hopper 13, and the sliding hopper 16 is adapted to the inner wall of the outer liquid collection hopper 13. A pull plate 40 is fixedly connected to the top of the sliding hopper 16. The water guide cover 15 is arched, and the pull plate 40 fits against the top of the water guide cover 15, causing the pull plate 40 to move the sliding hopper 16 up and down, and causing the sliding hopper 16 to collect the liquid. Debris inside the outer liquid collection hopper 13 is pushed out. Each of the outer liquid collection hoppers 13 is fixedly connected to one side with a connecting rod 23. The top of the support plate 2 is fixedly connected with a waterproof cover 24. Both sides of the buoy 1 are fixedly connected with a locking buckle 39. The bottom of the waterproof cover 24 has multiple drainage holes, which block the upper part of the waterproof cover 24 from the waves and prevent seawater from contaminating the sample. The drainage holes at the bottom drain the accumulated water. The top of the waterproof cover 24 is rotatably connected to a rotating frame 25. Multiple connecting rods 23 are fixedly connected to the inner wall of the rotating frame 25. Multiple wind buckets 26 are fixedly connected to the outside of the rotating frame 25. The wind buckets 26 are moved by the sea breeze, which drives the rotating frame 25 to rotate.

[0023] Both sides of the rotating cylinder 5 are fixedly connected to limit plates 29. Both sides of the reciprocating threaded rod 6 have limit grooves 30. The two limit plates 29 are slidably connected to and adapted to the two limit grooves 30. The reciprocating threaded rod 6 passes through a threaded ring 28 and is threadedly connected to the threaded ring 28, allowing the threaded ring 28 to limit the reciprocating threaded rod 6, thus enabling the reciprocating threaded rod 6 to move up and down during rotation. Both sides of the support ring 8 have integrally formed limit blocks 31. The two limit blocks 31 are slidably connected to the two limit plates 29. The limiting groove 30 is inside and adapted to two limiting grooves 30. The support ring 8 limits the limiting groove 30 through two limiting blocks 31, thereby driving the reciprocating threaded rod 6 to rotate. A circular plate 7 is fixedly connected to the top of the reciprocating threaded rod 6. Multiple upper support rods 27 are fixedly connected to the top of the circular plate 7. The other ends of the multiple upper support rods 27 are fixedly connected to multiple pull plates 40 respectively. A telescopic cover 32 is fixedly connected between the circular plate 7 and the support ring 8. The telescopic cover 32 is sleeved on the outside of the reciprocating threaded rod 6 to protect the reciprocating threaded rod 6.

[0024] A round rod 33 is fixedly connected to the top of the round plate 7. A platform 34 is fixedly connected to the top of the round rod 33. A reflective strip 35 is fixedly connected to the top of the platform 34. A top plate 36 is fixedly connected to the top of the reflective strip 35. A flagpole 37 is fixedly connected to the outside of the top plate 36. Colorful flags 38 are fixedly connected to one end of each of the multiple flagpoles 37. The round rod 33 drives the platform 34 to rotate. When the platform 34 rotates, it drives the reflective strip 35 and the top plate 36 to rotate. The reflective strip 35 is coated with reflective paint. When there is light, it reflects light from multiple angles to scare away seabirds. The top plate 36 drives the multiple flagpoles 37 and colorful flags 38 to rotate, thereby causing the multiple colorful flags 38 to flip and scare away the seabirds.

[0025] In use, this solution connects the buoy 1 to the monitoring location via a cable and locking buckle 39, allowing the ship to send the buoy 1 to the monitoring position. After the buoy 1 is pushed off the ship, it floats on the sea surface. Depending on the actual situation, the cable is tied to a fixed stake or the ship to collect samples of marine rainfall. The ship is dispatched periodically to collect the samples. By setting up the buoy 1 and locking buckle 39, the entire device can be anchored at the marine monitoring point, enabling long-term and stable collection of natural precipitation, avoiding device drift caused by wind, waves, or ocean currents, and ensuring the accuracy of the sampling point.

[0026] During rainfall, rainwater falls into the outer collection hopper 13. The water guide cover 15 directs the rainwater outwards, allowing it to accumulate inside. The screening hopper 16 filters out larger impurities such as marine debris and seaweed. As the water level rises in the outer collection hopper 13, exceeding the water passage trough 17 at its highest point, the rainwater flows through the trough 17 into the inner collection hopper 12. The water level rises in the inner collection hopper 12, allowing the rainwater to pass through the filter screen 19 into the storage tank 11. The filter screen 19 filters out large particles, reducing contamination of the rainwater sample. The rainwater sample is stored in the storage tank 11. To collect the sample, the handle 22 is used to unscrew the storage tank 11. Samples are collected and tested. A water guide cover 15 and a water channel 17 are installed on the top of the inner hopper 12. Rainwater can be guided along the water guide cover 15 into the outer hopper 13. After it is full, it enters the inner hopper 12 through the water channel 17, avoiding splashing caused by direct falling and improving rainwater collection efficiency. The double-layer structure of the outer hopper 13 and the inner hopper 12, combined with the matching design of the annular groove 20 and the support cylinder 10, can effectively separate rainwater from impurities, prevent impurities from entering the sampling area, and ensure the purity of the precipitation samples. The storage tank 11 and the support cylinder 10 are connected by threads and are equipped with a handle 22 for easy disassembly and installation, making it convenient for sampling personnel to retrieve samples or change sampling containers, thus improving the convenience of operation.

[0027] When buoy 1 floats on the sponge, the sea breeze causes multiple wind buckets 26 to rotate, which in turn drives the rotating frame 25 to rotate. The rotating frame 25, in turn, drives multiple connecting rods 23 to rotate, which in turn drives the outer liquid collection hopper 13 and the upper support rod 27 to rotate. When the outer liquid collection hopper 13 rotates, it drives the lower support rod 9 to rotate, causing the support ring 8 to rotate. The limiting blocks 31 on both sides of the support ring 8 guide the limiting grooves 30 on both sides of the reciprocating threaded rod 6, causing the reciprocating threaded rod 6 to rotate synchronously. The rotation of the reciprocating threaded rod 6 drives the rotating cylinder 5 to rotate as well. Simultaneously, the reciprocating threaded rod 6 is threadedly connected to the threaded ring 28, allowing it to move up and down during rotation. The reciprocating threaded rod 6, combined with the telescopic cover 32, achieves both up-and-down reciprocating motion and provides dust and water protection for the internal threaded structure, extending the service life of the device in high-humidity and high-salt marine environments. When the reciprocating threaded rod 6 moves up and down, it drives the circular plate... 7 moves, and the circular plate 7 drives multiple upper support rods 27 to rise, which in turn drives the pull plate 40 to rise. As the pull plate 40 rises, it drives the screening hopper 16 to rise as well. The screening hopper 16 moves upward inside the outer liquid collection hopper 13, pushing upward the impurities filtered by the screening hopper 16 that have fallen into the outer liquid collection hopper 13. When the inclined surface of the screening hopper 16 rises above the top of the outer liquid collection hopper 13, the impurities slide outward along the surface of the screening hopper 16, thus discharging the impurities. The impurities are then discharged through the screening hopper 16 and... The dual filtration structure of the filter screen 19 can effectively intercept larger impurities such as fallen leaves, bird droppings, and seaweed, preventing them from entering the liquid storage tank 11 and contaminating the samples. At the same time, the screening hopper 16 can be raised and lowered for cleaning, reducing the difficulty of daily maintenance. The wind hopper 26, rotating frame 25 and connecting rod 23 are linked together, which can use natural wind power to drive the outer liquid collection hopper 13 to rotate. With the help of the threaded ring 28, reciprocating threaded rod 6 and limiting structure, the periodic raising and lowering cleaning of the screening hopper 16 can be achieved. The degree of automation is high and no additional energy is required.

[0028] During the rotation of the circular plate 7, the circular plate 7 drives the circular rod 33 and the platform 34 to rotate, and the platform 34 drives the reflective strip 35 to rotate, which in turn drives the top plate 36 to rotate. When the top plate 36 rotates, it drives multiple flagpoles 37 to rotate, thereby causing multiple flagpoles 37 to flip multiple colored flags 38. The multiple colored flags 38 are all brightly colored, which is easy to scare away seabirds. At the same time, the rotating frame 25 is a long, twisted strip with a reflective paint coating. When exposed to sunlight, the reflection shines outward and scare away seabirds. During the rotation, it produces a reflective and fluttering effect, which can effectively drive away seabirds and reduce the contamination of samples by bird droppings.

[0029] Working principle: The device of this invention guides rainwater into the outer collection hopper (13) through the water guide cover (15). After preliminary filtration by the sieving hopper (16), the overflowing rainwater enters the inner collection hopper (12) through the water channel (17), and after secondary filtration by the filter screen (19), it flows into the storage tank (11) for storage. The wind-driven wind hopper (26) drives the rotating frame (25) to rotate. Through the linkage between the support ring (8) and the reciprocating threaded rod (6), the sieving hopper (16) is periodically raised and lowered to automatically clean impurities. At the same time, the reflective strip (35) and the colorful flag (38) rotate with the wind to drive away seabirds and ensure the cleanliness of the samples.
