Description

Technical Field

[0001] The utility model relates to the technical field of aquatic plant collection, mainly for carrying out aquatic plant collection operations from water enclosures, and specifically is a platform-type enclosure for quantitative sampling of submerged plants. Background Art

[0002] The quantitative collection operation of submerged plants is an important activity for water ecological research and management, aiming to scientifically evaluate and monitor the biomass, species composition of submerged plants in the aquatic ecosystem and their impact on water quality; according to the research purpose and specific conditions of the water area, a reasonable sampling plan is formulated. This includes determining the location, quantity of sampling points and the sampling period to ensure the representativeness and reliability of the data.

[0003] In some scientific ecological project researches, enclosures are used to control experimental conditions or evaluate the effect of specific submerged plant communities on purifying water quality. An enclosure is an isolation device for water body management, environmental protection and scientific research, and its main function is to create a relatively closed or controlled environment within a specific water area. In order to keep the enclosure in position on the water surface, a series of floating bodies are usually included in the design, such as inflatable floating barrels, foam strip bundles, flexible rod-shaped floating bodies, etc. These floating bodies provide the necessary buoyancy support to ensure that the top of the enclosure is above the water surface and can automatically adjust with the water level change. The enclosure is usually also provided with fixing and anchoring components, mainly including underwater anchoring cables, lower girdle ropes, fixing rods, etc., for fixing the enclosure at a predetermined position to prevent it from moving or drifting away. The enclosure is set in the water to define an area. The enclosure can prevent interference from external factors such as water flow, fish and other organisms, enabling researchers to more accurately evaluate the direct impact of submerged plants on water quality.

[0004] During sampling, a special quantitative sampling device for submerged plants is used. Usually, an operator sails a boat close to the side of the enclosure to carry out the collection operation of releasing and lifting. Since the operation is carried out on the water surface, it will cause limitations in the operation range, inconvenient operation, and even potential safety hazards. Usually, such an operation limits the range of aquatic plant collection to the edge area of the enclosure, making it very difficult to sample the submerged plants in the middle area, and the operation is also difficult, resulting in a reduction in the optional area of the aquatic plant distribution. In addition, during the process of salvaging and extracting the quantitative aquatic plant clamp, it is also easy to damage and consume the enclosure structure. Moreover, since the operator stands on the boat to operate during the process of extracting the aquatic plant clamp, the upward movement process of the aquatic plant clamp does not maintain a straight upward movement state, so it is easy to damage aquatic plants, disturb the bottom mud and even increase the entanglement risk during the salvaging process. Therefore, how to carry out the operation of releasing and collecting and recovering the quantitative aquatic plant clamp conveniently, stably and reliably is a problem that needs to be solved as soon as possible in the current industry. Summary of the Invention

[0005] In view of the many defects and deficiencies in the above-mentioned background art, the inventor has made improvements and innovations. After design and experiments, a platform-type enclosure for quantitative sampling of submerged plants is finally provided. This enclosure structure is equipped with a strip-shaped operation floating platform, on which a rotating hanging bracket is installed. The strip-shaped operation floating platform provides a supporting and stress-bearing platform, and in cooperation with the hanging rod on the rotating hanging bracket, it realizes the extension and expansion of the hanging position, achieves the controllability of the sampling position, and through the pulley block on the hanging rod to guide the hanging rope, realizes that the hanging and lowering process always maintains a straight up and down movement. Operators can perform convenient operations on the ship, significantly improving the efficiency, accuracy and safety of quantitative sampling of submerged plants, while reducing the impact on the environment and providing strong support for the research and management of aquatic ecosystems.

[0006] Specifically, the present invention is implemented as follows: A platform-type enclosure for quantitative sampling of submerged plants mainly includes:

[0007] (1) A floating enclosure, arranged in a square shape, and cooperates with an enclosure curtain to isolate the submerged plants in the area to be collected; usually composed of square floating structures connected to each other, and the four corners are connected and positioned using anchoring components;

[0008] (2) Mounting lugs, provided on the outer sides of the four corners of the floating enclosure, for docking and installing with the strip-shaped operation floating platform; common mounting lugs include metal buckles, quick connectors, etc., to ensure the integrity of the overall enclosure, and at the same time facilitate installation, disassembly and maintenance.

[0009] (3) A strip-shaped operation floating platform, in the shape of a strip-shaped floating platform, with docking lugs or mounting lugs provided on both sides of the long side, and can be respectively connected to one side of the floating enclosure through the docking lugs or mounting lugs, and connected to the docking lugs on the side of the operation ship; the strip-shaped operation floating platform can be composed of, for example, inflatable floating cylinders, foam bundles, flexible rod-shaped floating bodies, etc., and the size is preferably adapted to the length of the floating enclosure;

[0010] (4) Rotating hanger, installed on the strip-shaped operation floating platform, includes a rotatable boom. Pulley blocks are installed at both ends of the boom. The boom can extend to the middle of the enclosure. The lifting rope for lifting the quantitative waterweed collector can pass through the pulley block and can fix the lifting rope; the rotating hanger can rotate between above the middle of the enclosure and above the strip-shaped operation floating platform, is used to control the lifting rope to extend above the central area of the enclosure, and can provide the rope-receiving guidance of the lifting rope during the process of pulling up the quantitative waterweed collector; the rotating hanger is used to provide a controllable range between the lifting rope and the hull. By rotating, installation operations can be carried out in the area close to the hull side. After installation, the rotating hanger can be manipulated to place the waterweed clamp above the required placement position. After determining the position, then release the lifting rope. When extracting the sampled waterweed, it can also be used as an extended boom to make the lifting rope lift in a straight line direction. The pulley block on the boom provides guidance to the hull, so that the release and collection operations of the waterweed clamp can be carried out on the hull for a relatively far area.

[0011] (5) Automatic rope-receiving mechanism, installed on the operation ship. Docking lugs for docking with the strip-shaped operation floating platform are arranged on the side of the operation ship. The automatic rope-receiving mechanism can be connected and installed with the tail end of the lifting rope, and can pull and recycle the lifting rope after being started.

[0012] The working principle of the present utility model is as follows: In the structure of the present utility model, the floating enclosure serves as the basis of the entire system. It isolates the area to be sampled through a circular layout, ensuring the sealing of the sampling environment. The four corners are fixed by anchoring components, which are not only stable and reliable, but also ensure the overall stability of the enclosure through the interconnection of the square floating body structures. The design of the floating body structure is easy to install and maintain, and is suitable for different water conditions. The installation lugs are located outside the four corners of the enclosure, facilitating quick docking with the operation floating platform, and the operation floating platform can be set in the desired direction as required. The strip-shaped operation floating platform serves as an auxiliary buoyancy operation platform, which provides the necessary working surface and docking method. Its structural design (such as using inflatable floating cylinders, etc.) ensures buoyancy and stability, and is convenient for docking with the enclosure and the ship, meeting the operation requirements during the sampling process; after docking and installing with the hull, it can provide buoyancy on the operation side, and serves as the installation carrier of the rotating hanger, bearing the acting force generated during its operation. This is the core component of the system. Through the dual movement mechanisms of horizontal rotation and vertical rotation, it realizes the direction control and guidance of the lifting rope, so that the quantitative aquatic plant collector can be placed and retrieved in a straight vertical line manner. Moreover, this design enables the operator to efficiently sample remote areas even on the ship, greatly improving the sampling efficiency and safety. The automatic rope winding mechanism is driven by a shipboard motor, and the forward and reverse rotation of the motor is controlled manually, which simplifies the process of retrieving the lifting rope and reduces the manual burden. During the entire operation process, the operation floating platform provides the buoyancy support for the overall force, further reducing the load on the hull, making the operation process stable and gentle, and increasing safety. The use of quick-release buckles improves the convenience of operation, making the connection and separation of the lifting rope and the collector fast and safe.

[0013] The beneficial effects of the present utility model compared with the prior art are as follows:

[0014] 1. High-efficiency sampling and operation convenience: Through the design of the rotating hanger, the lifting rope can be flexibly controlled within a large range, realizing the precise placement and retrieval of aquatic plants in remote areas, and improving the efficiency of the sampling operation. At the same time, the operator can complete these operations on the ship without approaching the inner area of the enclosure, increasing the safety and convenience of the operation.

[0015] 2. Enhanced stability and adaptability: The buoyancy design of the strip-shaped operation floating platform further enhances the buoyancy and stability of the system, avoiding the possible inclination caused by the increased pulling force on one side of the hull during sampling extraction. The design of this system reduces the direct load dependence on the hull, reduces the risks during the operation process, and makes the sampling process smoother and safer.

[0016] 3. Simple installation and maintenance: The installation of hanging ears facilitates the quick docking and disassembly of the operation floating platform and the floating enclosure, and meets the installation in multiple directions and the simultaneous installation of multiple floating platforms. It can meet the long-term installation of the floating platform and the enclosure, or be installed as needed following the hull. It can adjust the configuration according to different sampling requirements, has multiple combination methods, strong practicability, and good flexibility and scalability.

[0017] 4. Improved sample quality: By isolating the area to be sampled through a closed floating enclosure, external interference can be effectively reduced, ensuring that the collected aquatic plant samples are purer, which is beneficial to the accuracy of scientific research or ecological monitoring.

[0033] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the technical solutions of the present utility model will be further described in detail below in conjunction with the attached drawings and specific embodiments. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0034] Embodiment 1: A platform-type enclosure for quantitative sampling of submerged plants. In actual use, the floating enclosure 1 is pre-arranged, and there are aquatic plants to be collected inside. The strip-shaped operation floating platform 3 can be used in several or single units. It can be pre-installed on one side of the floating enclosure 1 or can be towed by a boat close to the floating enclosure 1 and then docked and installed. After the operator brings the boat close to the outside of the strip-shaped operation floating platform 3 and keeps the hull stationary, manually fasten and install the docking lugs 12 corresponding to the side of the boat body with the installation lugs 11 on the strip-shaped operation floating platform 3. Pull out the end of the lifting rope 51 on the automatic rope-receiving mechanism 6, pass it through the tail end of the boom 41 and install it on the pulley block until it passes through the pulley block at the end of the boom 41, and then dock and install it with the installation hole on the quantitative aquatic plant collector 5. At this time, keep the automatic rope-receiving mechanism 6 stationary, suspend the quantitative aquatic plant collector 5 at the end of the boom 41. The operator controls the rotation of the boom 41, rotates the boom 41 together with the quantitative aquatic plant collector 5 to the middle area of the floating enclosure 1 and then keeps it fixed. Subsequently, start the automatic rope-receiving mechanism 6 on the boat. The automatic rope-receiving mechanism 6 flips and releases the lifting rope 51. The quantitative aquatic plant collector 5 moves straight down under the action of its own gravity into the water surface until it is lowered to the predetermined bottom position. Operate the quantitative aquatic plant collector 5 to actively clamp and cut off the aquatic plants. After collecting the corresponding aquatic plants in the net pocket of the quantitative aquatic plant collector 5, operate the automatic rope-receiving mechanism 6 to start. The automatic rope-receiving mechanism 6 rotates forward to recover the lifting rope 51, so that the quantitative aquatic plant collector 5 is lifted straight up along the lifting rope 51 until it reaches directly below the end of the boom 41. The automatic rope-receiving mechanism 6 stops and remains stationary. At this time, the quantitative aquatic plant collector 5 leaves the water surface, and the net pocket contains the collected aquatic plants. The operator controls the lateral rotation of the tail end of the boom 41 to make the end of the boom 41 located above the strip-shaped operation floating platform 3 and close to the boat. Then the operator manually removes the quantitative aquatic plant collector 5, recovers the lifting rope 51, and releases the docking lugs 12 and the installation lugs 11 to complete the operation.

[0035] Preferably, the rotary hanger 4 includes: a frustum-shaped base 31, fixedly installed in the middle of the strip-shaped operation floating platform 3, having a shaft hole at the top. The base is designed in a frustum shape, increasing the bottom contact area, thereby ensuring the stability of the rotary hanger 4 when installed in the middle of the strip-shaped operation floating platform 3. The base is installed on the floating platform through a sturdy fixing device to prevent displacement during operation. The shaft hole at the top is specially designed to accommodate the rotating support shaft 32, ensuring that the support shaft can rotate smoothly and at the same time bear the torque and vertical load generated during the rotary operation of the hanger. The rotating support shaft 32, the lower end of which is rotatably installed in the shaft hole; a hinge seat 33, installed at the upper end of the rotating support shaft 32, is connected to the boom 41 through a horizontally installed rotating shaft, enabling the boom 41 to rotate vertically up and down based on the hinge seat 33 as a fulcrum and to rotate axially based on the rotating support shaft 32.

[0036] During use, the truncated cone base 31 is the foundation of the entire hanger, fixed to the central area of ​​the strip-shaped operating platform 3. Its unique truncated cone shape is designed to increase the contact range between the bottom surface and the platform, improve the stability of the overall structure and the uniformity of load distribution, and is used to transfer the force generated by the boom 41 and the rope 51 during operation to the strip-shaped floating platform; an axial hole is provided in the center of the base for installing the rotating support shaft 32 to realize the function of rotating the boom 41, and the upper end is connected to the hinge seat 33, allowing the entire boom 41 to rotate 360 ​​degrees around the axis while also being able to tilt up and down with the hinge point as a fulcrum to adjust the height of the front end of the boom 41. This design not only allows the boom 41 to swing up and down around its own vertical axis, but also to rotate with the support shaft on the horizontal plane. This dual degree of freedom of movement greatly enhances the operational flexibility and scope of application of the hanger. The main design purpose is to be able to control the end of the boom 41 to be close to or away from the platform.

[0038] In actual use, the first fixed pulley 42 is used to guide the turning of the lifting rope 51, and the second fixed pulley 43 is used to cooperate with the guide wheel 44. Through the rope path between the two fixed pulleys, the force direction can be changed, and the rope will not derail or entangle during the lifting process. At the same time, it can also assist in adjusting the direction of the rope and optimize the distribution of force during the lifting process. The door frame 412 is used to prevent the lifting rope 51 from falling out and ensure the stability of the lifting rope 51 during the retraction and release process.

[0039] Preferably, a hook 45 is provided on the door frame 412 for fixing the tail end of the suspension rope 51, and an operating handle 46 is installed at the bottom of the tail end of the suspension rod 41. After the operation is completed, the quantitative aquatic plant collector 5 and the strip-shaped operating platform 3 can also be stored and managed together. At this time, the installation state of the suspension rope 51 is still maintained, but the excess suspension rope 51 can be hung on the hook 45, which is convenient for direct use next time. The operating handle is used to control the rotation direction of the suspension rod 41. Preferably, a buckle ring or a clamping rope 47 that can be rotated up and down is installed in the middle of the outer side surface of the strip-shaped operating platform 3. The buckle ring or the clamping rope 47 can be put on the operating handle 46, and limit the upward tilt of the tail end of the suspension rod 41, so as to keep the front end of the suspension rod 41 above the water surface. Such a design is to limit the turning of the operating handle by means of a buckle ring or a clip rope 47, while limiting the downward movement of the front end of the boom 41, and keeping the front end of the boom 41 in an upward trend. In this way, no manual control is required, and the operator can operate the aquatic plant clip to collect aquatic plants, or operate the motor to control the lifting and lowering, and the operation can be completed by one person.

[0040] Preferably, an anti-drop hole 48 is provided below the end of the suspension rod 41 , and the suspension rope 51 passes through the anti-drop hole 48 . The orientation of the anti-drop hole 48 is designed to be tangent to the end edge of the first fixed pulley 42 , so as to prevent the suspension rope 51 from detaching from the first fixed pulley 42 .

[0041] Preferably, a fixing slot 49 is installed at one end of the strip-shaped operating platform 3, and the suspension rod 41 can be placed in the fixing slot 49 to limit the positioning of the suspension rod 41 and keep it stable. When the strip-shaped operating platform 3 is stored, the suspension rod 41 is rotated to the side that fits the surface of the strip-shaped operating platform 3 for storage. At this time, one end of the suspension rod 41 is placed in the fixing slot 49 to prevent it from deflecting.

[0042] Preferably, quick-connect buckles 52 are provided at both ends of the sling 51, and the quick-connect buckles 52 at the end can be connected and installed with the docking buckles provided on the retracting roller 73; the quick-connect buckle 52 at the front end can be connected and installed with the docking buckle on the quantitative aquatic plant collector 5.

The battery can be placed in the support, and the battery can be movably disassembled and installed for easy charging. The transmission component 72 can be installed and docked using a transmission chain or a transmission belt, and can transmit the power output of the ship-borne motor 71 to the retracting roller 73. The quick-connect buckles 52 at both ends of the hanging rope 51 are designed to facilitate connection, installation, disassembly and storage with the quantitative aquatic plant collector 5 and the automatic rope collection mechanism 6.
