Description

Technical Field

[0001] This invention relates to the technical field of marine biological sample collection, specifically to a marine biological sample collection device. Background Technology

[0002] A marine life sampling net is a tool specifically designed to capture and collect fish eggs, larvae, algae, and other small marine organisms in the ocean. It typically consists of a net opening ring, a net cover, and a collector. There are two ways to use a marine life sampling net: one is to fix the collection net to a connecting rod and manually swing the net to collect organisms from the sea surface; the other is to extend the sampling net into the sea and retrieve it after a certain period of time.

[0003] Both of these methods require long periods of time at sea to collect marine organisms, leading to increased consumption of manpower and resources. Furthermore, the sampling is limited to a single location and cannot be performed at different times. The movement of marine organisms when entering the sea by boat also reduces the accuracy of the sampling. Summary of the Invention

[0004] The purpose of this invention is to provide a marine biological sample collection device to solve the problems mentioned in the background art.

[0005] To achieve the above object, the present invention provides the following technical solutions: A marine biological sample collection device includes a suspension frame, an airbag installed inside the suspension frame, a sampling component disposed on the lower side of the airbag, a connecting tube installed on the lower side of the spherical surface of the airbag, the end of the connecting tube away from the airbag being connected to the sampling component, and a collection component installed on the lower side of the suspension frame, with the sampling component disposed inside the collection component.

[0006] Furthermore, the sampling device includes multiple sampling tubes, which are disposed within the collection device. A piston is slidably connected inside each sampling tube, and a connecting member is installed between two adjacent pistons. A filter screen is installed on the side of the sampling tube away from the piston. The end of the connecting tube away from the air bladder is connected to the lowest sampling tube, and the connecting tube is disposed on the side of the piston away from the filter screen. Multiple first one-way valves are installed on the annular surface of the sampling tube, and a second one-way valve is installed on the side of the sampling tube away from the piston. The second one-way valve is disposed on the side of the filter screen away from the first one-way valve.

[0007] Furthermore, the connector includes a connecting rod, with connecting rods installed on both the upper and lower sides of the piston. A limiting ring is installed on the annular surface of the upper connecting rod, and the limiting ring is in contact with the sampling cylinder. Circular holes are opened on both the upper and lower sides of the sampling cylinder, and the connecting rods are inserted into the circular holes. A first connecting rope is installed between two adjacent connecting rods.

[0008] Furthermore, the sampling tube is mirror-cut, and an internally threaded tube and an externally threaded tube are respectively installed at the two ends of the cut sampling tube, and the internally threaded tube and the externally threaded tube are threadedly connected.

[0009] Furthermore, the collection device includes multiple collection nets, the sampling tube is installed inside the collection nets, a mesh ring is installed at the opening of the collection net, a second connecting rope is installed between each pair of mesh rings, and a guide is installed inside the mesh ring, the guide being disposed inside the collection net.

[0010] Furthermore, the guide includes a bracket, which is installed inside the mesh opening. Support plates are installed on both the upper and lower sides of the bracket. A support rod is installed on the side of the support plate facing the inside of the collection net. A guide plate is installed on the end of the support rod away from the bracket. The guide plate is connected to the tail of the collection net.

[0011] Furthermore, a spool is installed at the end of the suspension frame away from the piston, and the second connecting rope is wound inside the spool.

[0012] Furthermore, a positioning anchor is installed on the lower side of the annular surface of the bottommost mesh ring.

[0013] Furthermore, multiple extrusion plates are hinged to the upper surface of the suspension frame, and the extrusion plates are in contact with the airbag.

[0014] Furthermore, a locator is installed inside the airbag.

[0015] Beneficial effects:

[0016] 1. This invention utilizes a connecting pipe to connect an airbag to the lowest sampling cylinder. The airbag is positioned on the water surface. When waves are present, the resulting water level difference compresses the airbag, allowing air inside to enter the lowest sampling cylinder through the connecting pipe. This air then compresses the piston within the lowest sampling cylinder, causing it to move within the cylinder. The pistons in the other sampling cylinders are connected by a first connecting rope and a connecting rod. When the piston in the lowest sampling cylinder moves towards the filter screen, water is forced out of the sampling cylinder through a second one-way valve. The other sampling cylinders replicate this operation, creating negative pressure within them. When the waves subside and the airbag returns to its position on the water surface, the gas in the lowest sampling cylinder re-enters the airbag through the connecting pipe. The negative pressure in the other sampling cylinders causes the pistons to return to their original positions. At this point, negative pressure is generated in the space between the piston and the second one-way valve, allowing external water to flow into the sampling cylinder through the first one-way valve, thereby enabling the collection of marine biological samples.

[0017] 2. This invention features circular holes on both the upper and lower sides of the sampling tube, with a connecting structure consisting of a connecting rod and a first connecting rope installed inside each hole. This connecting structure connects the pistons inside multiple sampling tubes, allowing for simultaneous biological collection from multiple tubes and increasing the diversity of marine biological samples collected from different locations. Furthermore, multiple compression plates are hinged to the upper surface of the suspension frame. When waves impact the compression plates, they compress the air bladder, making it easier for the gas inside the air bladder to be squeezed into the lowest sampling tube. When the sea is calm, the suspension frame can be placed on a boat, and the compression plates can be manually swung to compress the air bladder, allowing the gas inside the air bladder to enter the lowest sampling tube, thus increasing the applicability of this sampling device.

[0018] 3. The present invention connects multiple collection nets to the lower surface of the suspended frame via a second connecting rope, and installs a guide structure consisting of a bracket, a support rod, and a guide plate inside the collection net. The guide structure is used to make the opening of the collection net face the water flow, thereby improving the collection of marine organisms by the collection net and increasing the amount of marine organisms collected in the sampling tube.

[0027] See also Figures 1 to 7 The marine biological sample collection device provided by the present invention includes a suspension frame 1, which is suspended on the water surface. Multiple mesh rings 5 ​​are provided on the lower surface of the suspension frame 1. Adjacent mesh rings 5 ​​are connected by a second connecting rope 4, and the uppermost mesh ring 5 is also connected to the suspension frame 1 by a second connecting rope 4. A collection net 10 is then installed on the mesh rings 5. The collection net 10 is used to collect marine biological samples. A support 12 is installed inside the mesh rings 5. Support plates 13 are installed on both the upper and lower sides of the support 12. A support rod 11 is installed on the side of the support plate 13 facing the inside of the collection net 10. A guide plate 7 is installed at the end of the support rod 11 away from the support 12. The guide plate 7 is connected to the tail of the collection net 10. Seawater is fluid; when the flowing seawater comes into contact with the guide plate 7, it will cause the guide plate 7 to deflect. By installing a guiding structure composed of the support 12, support rod 11, and guide plate 7 inside the collection net 10, the opening of the collection net 10 faces the water flow, improving the collection efficiency of the collection net 10 for marine biological samples.

[0028] An airbag 3 is installed inside the suspended frame 1. A sampling cylinder 14 is set on the lower side of the airbag 3 and is placed inside the collection net 10. A connecting tube 8 is installed on the lower side of the spherical surface of the airbag 3. The end of the connecting tube 8 away from the airbag 3 is connected to the lowermost sampling cylinder 14. A piston 22 is slidably connected inside the sampling cylinder 14. Circular holes are opened on both the upper and lower sides of the sampling cylinder 14. A connecting rod 19 is inserted into the circular hole and connected to the piston 22. A first connecting rope 9 is installed between two adjacent connecting rods 19. A limiting ring 20 is installed on the annular surface of the upper connecting rod 19. The limiting ring 20 is in contact with the sampling cylinder 14. The pistons 22 in multiple sampling cylinders 14 are connected by the first connecting rope 9 and the connecting rod 19, so that multiple pistons 22 can move simultaneously inside the sampling cylinder 14.

[0029] Multiple first one-way valves 15 are installed on the annular surface of the sampling tube 14. The first one-way valves 15 only allow external water to enter the sampling tube 14. A second one-way valve 18 is installed on the side of the sampling tube 14 away from the piston 22. The second one-way valve 18 only allows water to flow out of the sampling tube 14. A filter screen 21 is installed on the side of the sampling tube 14 away from the piston 22.

[0030] It should be noted that the filter screen 21 is located between the second one-way valve 18 and the first one-way valve 15, and the connecting pipe 8 is located on the side of the piston 22 away from the filter screen 21. The filter screen 21 is used to filter the marine organisms collected in the sampling tube 14, so that when the water in the sampling tube 14 is discharged through the second one-way valve 18, the organisms in the sampling tube 14 remain in the sampling tube 14.

[0031] In use, the airbag 3 is connected to the lowermost sampling cylinder 14 via the connecting pipe 8. The airbag 3 is placed on the water surface. When there are waves on the sea surface, the waves create a water level difference, causing the airbag 3 to enter the sea. The seawater can then compress the airbag 3, allowing the air inside the airbag 3 to enter the lowermost sampling cylinder 14 through the connecting pipe 8, and compress the piston 22 inside the lowermost sampling cylinder 14, causing the piston 22 to move within the sampling cylinder 14. The pistons 22 in the other sampling cylinders 14 are connected to the connecting rod 19 via the first connecting rope 9. When the piston 22 in the lowermost sampling cylinder 14 moves towards the filter screen 21, the water in the sampling cylinder 14 is squeezed out through the second one-way valve 18. Other sampling tubes 14 also replicate this operation, generating negative pressure within them. When the airbag 3 returns to its position on the sea surface after the waves subside, the gas in the lowest sampling tube 14 re-enters the airbag 3 through the connecting pipe 8. The negative pressure in the other sampling tubes 14 causes the piston 22 to return to its original position. At this time, negative pressure is generated in the space between the piston 22 and the second one-way valve 18, allowing external water to flow into the sampling tube 14 through the first one-way valve 15, thereby achieving the collection of marine biological samples. Furthermore, since different sampling tubes 14 are set in different positions, marine biological samples from different locations can be obtained, improving the diversity of marine biological samples collected from different locations.

[0032] like Figure 5 As shown in the cross-section of the sampling tube 14, an internally threaded tube 16 and an externally threaded tube 17 are respectively installed at the two ends of the sampling tube 14. The internally threaded tube 16 and the externally threaded tube 17 are threaded together, and the two sections of the sampling tube 14 are connected by the internally threaded tube 16 and the externally threaded tube 17. After the sampling tube 14 has finished sampling, the internally threaded tube 16 and the externally threaded tube 17 are separated, and then the samples on the sampling tube 14 and the filter screen 21 can be collected.

[0033] A reel 23 is installed at the end of the suspension frame 1 away from the piston 22. The second connecting rope 4 is wound inside the reel 23. The position of the net ring 5 in the ocean is adjusted by using the reel 23, so that multiple sampling tubes 14 can be used in sea areas of different depths. At the same time, by adjusting the position of the net ring 5, the sampling tubes 14 can collect marine organisms from different locations.

[0034] To prevent the suspended frame 1 from drifting aimlessly on the ocean, a positioning anchor 6 is installed on the lower side of the annular surface of the bottom mesh ring 5. The positioning anchor 6 is used to limit the position of the suspended frame 1. A locator is installed inside the airbag 3 to locate the release position of the sampling tube 14, which facilitates the retrieval of the sampling tube 14.

[0035] Multiple extrusion plates 2 are hinged to the upper surface of the suspension frame 1. The extrusion plates 2 are in contact with the airbag 3. When the waves hit the extrusion plates 2, the extrusion plates 2 will squeeze the airbag 3, making it easier for the gas in the airbag 3 to be squeezed into the bottom sampling tube 14. When the sea is calm, the suspension frame 1 can be placed on a boat, and the extrusion plates 2 can be manually swung to squeeze the airbag 3, so that the gas in the airbag 3 can enter the bottom sampling tube 14, thus increasing the scope of use of the sampling device.

[0036] In use, the suspension frame 1, the net rings 5 ​​connected by multiple second connecting ropes 4, and the collection net 10 are first placed in the ocean. When the positioning anchor 6 reaches the seabed, the length of the second connecting ropes 4 is adjusted by the reel 23 to raise the position of the uppermost net ring 5 and drive the other net rings 5 ​​to rise together, so that the second connecting ropes 4 are in a straight state. At this time, the sampling device is released.

[0037] When the waves hit the squeezing plate 2, the squeezing plate 2 squeezes the airbag 3. The gas in the airbag 3 enters the bottom sampling cylinder 14 through the connecting pipe 8. When the airbag 3 is completely submerged in the seawater, the seawater further squeezes the airbag 3, causing the air in the airbag 3 to be further squeezed into the bottom sampling cylinder 14, increasing the distance that the piston 22 moves in the sampling cylinder 14. When the piston 22 moves and the limiting ring 20 comes into contact with the sampling cylinder 14, the piston 22 is blocked by the limiting ring 20 and cannot move. At this time, the piston 22 has moved the maximum distance in the sampling cylinder 14. At this time, the piston 22 has not moved to the first one-way valve 15. When the bottom piston 22 moves in the sampling cylinder 14, the first connecting rope 9 and the connecting rod 19 drive the other pistons 22 to move together.

[0038] When piston 22 moves toward filter screen 21, seawater in sampling tube 14 passes through filter screen 21 and is discharged through second one-way valve 18. Marine biological samples collected in the seawater are retained in sampling tube 14 by filter screen 21. After the waves pass, airbag 3 is resuspended on the sea surface, and air in the lowest sampling tube 14 returns to airbag 3 through connecting pipe 8. Outside seawater enters sampling tube 14 through first one-way valve 15. When piston 22 moves in sampling tube 14, negative pressure space is generated on the side of piston 22 away from filter screen 21 in other sampling tubes 14. When the lowest piston 22 returns to its original position, the negative pressure space on the side of piston 22 away from filter screen 21 drives piston 22 to reset. When the sea surface is calm, suspension frame 1 can be placed on a boat, and the squeezing plate 2 can be manually swung to squeeze airbag 3, so that gas in airbag 3 enters the lowest sampling tube 14, increasing the scope of use of the sampling device.

[0039] When the seawater flows, the guiding structure composed of the support 12, the support rod 11 and the guide plate 7 drives the position of the mesh ring 5 to rotate, and makes the opening of the collection net 10 face the opposite direction of the seawater flow, which makes it easier for marine organisms to enter the collection net 10. The sampling tube 14 set in the filter net 21 can increase the probability of capturing marine organisms and increase the probability of sampling marine organisms.

[0040] After sampling is completed, the sampling tube 14 is positioned by the locator and the multiple sampling tubes 14 are retrieved. The inner threaded tube 16 and the outer threaded tube 17 are separated. Then, the samples on the sampling tube 14 and the filter screen 21 are collected. At this time, the collection of marine organisms collected in the sampling tube 14 is completed.

Many modifications and variations will be apparent to those skilled in the art.
