Description

Technical Field

[0001] This utility model relates to the field of seagrass bed sampling technology, specifically a seagrass bed vegetation sampling device. Background Technology

[0002] Seagrass beds refer to seagrass ecosystems dominated by one or more seagrass plants. Seagrass is the only type of angiosperm on Earth that can live entirely in seawater. The main functions of seagrass beds include:

[0003] Providing habitats: Seagrass beds provide habitats, shelters, and breeding grounds for various economically important fish and crustaceans, enhancing biodiversity and habitat diversity in coastal waters. Improving water quality: Seagrass beds reduce suspended solids in water and absorb nutrients, thereby improving water quality. Promoting nutrient cycling: Seagrass beds participate in nutrient regeneration and cycling through the growth and export of organic matter, providing productivity for the entire ecosystem. Simultaneously, dead seagrass forms the basis of complex food chains; bacteria decompose seagrass humus, providing food for sandworms, crabs, and some filter feeders such as sea anemones and sea squirts. Carbon capture and sequestration: Seagrass beds are one of the most effective carbon capture and sequestration systems globally, playing a vital role in addressing climate change. Strengthening seabeds and coastlines: Seagrass grows on silty or sandy sediments along coastal coasts, accumulating mud, reducing wave impact, and minimizing sand erosion, thus strengthening and protecting the seabed and coastline. Economic and cultural value: Seaweed can be used to weave mats, mattresses, baskets and other daily necessities. It can also be used as an insulator, feed ingredient and cosmetic ingredient, and has certain economic value.

[0004] However, in practical applications, traditional seagrass bed vegetation sampling methods often rely on manual operation by divers. This is not only complex and inefficient, but also makes it difficult to guarantee the integrity and accuracy of the samples. Especially in deep sea or complex seabed topography, the difficulty and danger for divers increase significantly. Furthermore, traditional sampling methods are easily affected by natural factors such as weather and sea conditions, making sampling difficult and thus impacting the efficiency of seagrass bed vegetation sampling. Utility Model Content

[0005] The purpose of this invention is to provide a seagrass bed vegetation sampling device to address the problem that traditional seagrass bed vegetation sampling methods, as described in the background, often rely on manual operation by divers. This is not only complex and inefficient, but also makes it difficult to guarantee the integrity and accuracy of the samples. Especially in deep sea or complex seabed topography, the difficulty and danger for divers increase significantly. Furthermore, traditional sampling methods are easily affected by natural factors such as weather and sea conditions, making sampling difficult and thus impacting the efficiency of seagrass bed vegetation sampling.

[0006] To achieve the above objectives, the present invention provides the following technical solution: it includes a submersible frame body, wherein a first electric telescopic rod is fixedly installed through the four corners of the lower end of the submersible frame body, a telescopic groove is fixedly installed on the telescopic part of the lower end of the first electric telescopic rod, a support spring is fixedly installed at the top of the telescopic groove, a support foot for supporting the seabed is fixedly installed at the lower end of the support spring, and a press limit switch is fixedly installed at the upper end of the support foot;

[0007] The upper four corners of the submerged frame body are fixedly installed with lifting rings. A second electric telescopic rod is fixedly installed through the upper part of the submerged frame body. A lifting connecting rod is fixedly installed on the lower telescopic part of the second electric telescopic rod. Limiting sliding rods are fixedly installed on both sides of the upper part of the lifting connecting rod. A sampling box is fixedly installed on the lower part of the lifting connecting rod. An observation camera is fixedly installed at the top of the sampling box. Opening grooves are opened through both sides of the lower part of the sampling box. A sampling gate for sampling seagrass bed vegetation is movably connected to the inner wall of the opening groove. A third electric telescopic rod is fixedly installed on the outer side of the sampling box. A horizontal connecting rod is fixedly installed on the outer telescopic part of the third electric telescopic rod.

[0008] Preferably, there are several first electric telescopic rods, which are symmetrically distributed at the four corners of the lower end of the submerged frame body.

[0009] Preferably, there are several support springs, which are symmetrically distributed at the top of the telescopic groove. The upper end of the support foot is movably connected to the lower end of the inner wall of the telescopic groove. The press limit switch is electrically connected to the first electric telescopic rod through a wire.

[0010] Preferably, there are four lifting rings, which are symmetrically distributed at the four corners of the upper end of the submerged frame body, and there are two second electric telescopic rods, which are symmetrically distributed on both sides of the upper end of the submerged frame body.

[0011] Preferably, there are two limiting slide rods, which are symmetrically distributed on both sides of the upper end of the lifting link, and the upper end of the limiting slide rod is connected to the upper end of the submersible frame body through and fits.

[0012] Preferably, there are two opening grooves, which are symmetrically distributed on both sides of the lower end of the sampling box, and the inner end of the sampling gate is movably connected to the inner wall of the sampling box.

[0013] Preferably, there are four third electric telescopic rods, with two third electric telescopic rods forming a group. The two groups of third electric telescopic rods are symmetrically distributed on the outside of the sampling box, and the sampling gate is fixedly installed on the inside of the horizontal connecting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the main body of the submersible frame sinks to the seabed, it is supported by the support feet on the seabed surface. When the support feet are supported on the seabed surface, the first electric telescopic rod is activated and extended. When the first electric telescopic rod extends and retracts, it simultaneously drives the support feet to move up and down. When the support feet move up and down, they support the undulating seabed surface. At the same time, when the support feet move down to support the seabed surface, they push the compression spring in the opposite direction, which in turn drives the limit switch to move upward. When the limit switch moves upward, the top of the telescopic groove presses against the limit switch. When the limit switch is pressed, it controls the first electric telescopic rod to close, so that the first electric telescopic rod stops extending downward. This allows the main body of the submersible frame to be lowered to the seabed while being supported on the undulating seabed surface.

[0016] This invention also allows for the extension of a second electric telescopic rod when the main body of the submersible frame is supported on the seabed. When the second electric telescopic rod extends, it drives a lifting link to move downwards in a straight line. This downward movement of the lifting link causes the sampling box to move downwards in a straight line, enclosing the seagrass bed vegetation. Once the sampling box has enclosed the seagrass bed vegetation, a third electric telescopic rod is simultaneously activated to retract. When the third electric telescopic rod retracts, it drives a horizontal link to move inwards. This inward movement of the horizontal link causes the sampling gate to move in a straight line along the inner wall of the opening groove. As the sampling gate moves inwards in a straight line, it grasps and samples the seagrass bed vegetation, thus facilitating sampling of the seagrass bed vegetation. Attached Figure Description

[0022] Please see Figure 1-3 This utility model provides a technical solution for a seagrass bed vegetation sampling device: it includes a submerged frame body 1, with a first electric telescopic rod 2 fixedly installed through the four corners of the lower end of the submerged frame body 1, and there are several first electric telescopic rods 2, which are symmetrically distributed at the four corners of the lower end of the submerged frame body 1. The telescopic part of the lower end of the first electric telescopic rod 2 is fixedly installed with a telescopic groove 3, and a support spring 4 is fixedly installed at the top of the telescopic groove 3, and there are several support springs 4, which are symmetrically distributed at the top of the telescopic groove 3. The lower end of the support spring 4 is fixedly installed with a support foot 5 for supporting the seabed, and the upper end of the support foot 5 is limited and movably connected to the inner wall of the lower end of the telescopic groove 3, so that the upper end of the support foot 5 is elastically limited by the support spring 4 and the telescopic groove 3. The upper end of the support foot 5 is fixedly installed with a press limit switch 16, and the press limit switch 16 is electrically connected to the first electric telescopic rod 2 through a wire, so that the first electric telescopic rod 2 is closed by pressing the limit switch 16.

[0023] Four lifting rings 6 are fixedly installed at the four corners of the upper end of the submerged frame body 1, symmetrically distributed at the four corners of the upper end of the submerged frame body 1. This allows the submerged frame body 1 to be lifted or lowered by lifting equipment in conjunction with the lifting rings 6. Two second electric telescopic rods 7 are fixedly installed through the upper end of the submerged frame body 1, symmetrically distributed on both sides of the upper end of the submerged frame body 1. A lifting connecting rod 8 is fixedly installed on the telescopic part of the lower end of the second electric telescopic rod 7. Two limit sliding rods 9 are fixedly installed on both sides of the upper end of the lifting connecting rod 8, symmetrically distributed on both sides of the upper end of the lifting connecting rod 8. The upper end of the limit sliding rod 9 is movably connected to the upper end of the submerged frame body 1, allowing the lifting connecting rod 8 to be linearly limited by the limit sliding rod 9. A certain device is fixedly installed at the lower end of the lifting connecting rod 8. The sampling box 10 has an observation camera 11 fixedly installed at the top. The lower end of the sampling box 10 has two through-holes slids 12, which are symmetrically distributed on both sides of the lower end of the sampling box 10. The inner wall of the through-hole slids 12 is movably connected to a sampling gate 13 for sampling seagrass bed vegetation, and the inner end of the sampling gate 13 is movably connected to the inner wall of the sampling box 10. The outer side of the sampling box 10 is supported and fixedly installed with a third electric telescopic rod 14, and there are four third electric telescopic rods 14. Every two third electric telescopic rods 14 form a group, and the two groups of third electric telescopic rods 14 are symmetrically distributed on the outer side of the sampling box 10. The telescopic part of the outer end of the third electric telescopic rod 14 is fixedly installed with a horizontal connecting rod 15, and the sampling gate 13 is fixedly installed on the inner side of the horizontal connecting rod 15.

[0024] Working principle: In use, this utility model uses a hoisting device with lifting rings 6 to lower the main body 1 of the submersible frame, causing it to sink to the seabed where sampling is required. When the main body 1 sinks to the seabed, it is supported by the support legs 5. When the support legs 5 are supported on the seabed, the first electric telescopic rod 2 is activated to extend and retract. When the first electric telescopic rod 2 extends and retracts, it simultaneously moves the support legs 5 up and down to adjust their position. When the support legs 5 move up and down, they support the undulating seabed surface. Meanwhile, when the support foot 5 moves downward to support the seabed, the support foot 5 will push the compression support spring 4 in the opposite direction and drive the pressing limit switch 16 to move upward. When the pressing limit switch 16 moves upward, the top of the telescopic groove 3 will press the pressing limit switch 16. When the pressing limit switch 16 is pressed, the pressing limit switch 16 will control the closing of the first electric telescopic rod 2, so that the first electric telescopic rod 2 stops extending downward, thereby realizing the lowering of the submersible frame body 1 to the seabed while facilitating the support of the submersible frame body 1 on the undulating seabed surface.

[0025] When the main body 1 of the submerged frame is supported on the seabed, the second electric telescopic rod 7 is extended by control. When the second electric telescopic rod 7 extends, it drives the lifting link 8 to move downward in a straight line. When the lifting link 8 moves downward in a straight line, it drives the sampling box 10 to move downward in a straight line. When the sampling box 10 moves downward in a straight line, it surrounds the seagrass bed vegetation inside. When the sampling box 10 surrounds the seagrass bed vegetation inside, the third electric telescopic rod 14 is retracted by synchronous control. When the third electric telescopic rod 14 retracts, it drives the horizontal link 15 to move inward. When the horizontal link 15 moves inward, it drives the sampling gate 13 to move in a straight line along the inner wall of the opening slide 12. When the sampling gate 13 moves in a straight line inward, it grabs and samples the seagrass bed vegetation, thereby facilitating the sampling of the seagrass bed vegetation.
