Description

[0002] Ecological floating plants refer to those floating plants that can effectively improve water quality, provide habitats for aquatic organisms, and promote the health and stability of aquatic ecosystems. They are often important tools in water body ecological management and restoration projects, and have advantages such as purifying water quality, inhibiting algae growth, providing sheltered habitats for fish, and improving the aquatic environment.

[0003] However, since the roots of floating plants are suspended in the water, they can easily drift to the shore when blown by the wind or when the water surface is undulating, making it impossible for floating plants to grow in the central area of ​​a large body of water. Furthermore, their roots are easily eaten by herbivorous or omnivorous fish in the water. Therefore, an ecological aquatic plant protective net is proposed. Summary of the Invention

[0017] 2. This application can anchor the protective mechanism at a designated position in the water. When the water level rises and falls normally, the bottom anchor can always apply the same pulling force to the protective mechanism above, so that it will not drift due to changes in the water level. At the same time, it can ensure that the protective mechanism always floats on the water surface during violent fluctuations in the water level, so that the floating plants planted in it will not be overturned by the waves. After the water surface calms down, as long as the position of the anchor remains unchanged, the position of the protective mechanism will also remain unchanged. Attached Figure Description

[0030] The technical solution of the present invention will now be clearly and completely described 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.

[0031] Please refer to Figures 1-7This invention provides a technical solution: an ecological aquatic plant protective net, including a protective mechanism 1. The protective mechanism 1 includes a cylindrical protective net 14, floating rings 12 and circular mesh plates 13 for fixing the top and bottom, and a horizontal frame 6 fixedly installed below the protective mechanism 1. An anchor mechanism 2 and two reset mechanisms 3 are fixedly installed at the bottom of the horizontal frame 6. The anchor mechanism 2 is located between the two reset mechanisms 3. The anchor mechanism 2 includes a mounting frame 21 and a winding drum 22 that rotates within and passes through the mounting frame 21. A cable 23 is wound around the winding drum 22. A ground anchor 4 is fixedly installed at the end of the cable 23 away from the winding drum 22. The cable 23 and the ground anchor 4 cooperate to ensure that the length between the winding drum 22 and the ground anchor 4 remains taut when the water surface rises and falls slowly. The anchor mechanism 2 and the two reset mechanisms 3 are connected by the same detachable prism 7. The anchor mechanism 2 and the two reset mechanisms 3 cooperate to anchor the protective mechanism 1 when the water surface rises and falls continuously.

[0032] A ring plate 11 is fixedly installed on the top of the cylindrical protective net 14, and a cylindrical reinforcing frame 15 is fixedly installed on the outside of the cylindrical protective net 14. The top of the cylindrical reinforcing frame 15 is fixedly connected to the ring plate 11, the floating ring 12 is fixed on the top of the ring plate 11, and multiple partition posts 16 are fixedly installed at the bottom of the cylindrical reinforcing frame 15. The cross frame 6 is fixedly connected to the corresponding multiple partition posts 16.

[0033] Two side plates 17 are fixedly installed on the side of the annular plate 11. The reset mechanism 3 includes a net cylinder 33 fixed to the bottom of the corresponding side plate 17 and a mounting frame 31 fixed to the bottom of the cross frame 6. A winding drum 32 is rotatably installed through the mounting frame 31. A cable 35 is wound around the winding drum 32. The end of the cable 35 away from the winding drum 32 extends into the net cylinder 33 and a float 34 is fixedly installed thereon. The float 34 is slidably installed in the net cylinder 33. The side plate 17 is used to place the float 34 to be discharged from the top of the net cylinder 33. Two through holes 61 are opened on the cross frame 6, and the two cables 35 pass through the corresponding through holes 61 respectively.

[0034] The winding direction of cable 25 on take-up drum 22 is opposite to the winding direction of cable 13 on take-up drum 122. Take-up drum 122 is coaxially arranged with the two take-up drums 222. Prism 7 passes through take-up drum 122 and the two take-up drums 222 and is detachably connected to them.

[0035] Both sides of the mounting frame 21 are equipped with a torsion mechanism 24. The torsion mechanism 24 includes a friction wheel ring 241 fixedly sleeved on the winding drum 22 and four end plates 242 fixedly distributed in a rectangular shape on the side of the mounting frame 21. The same guide rod 243 is fixedly installed between the corresponding end plates 242. Friction columns 244 are slidably sleeved on both guide rods 243. Both friction columns 244 abut against the side of the friction wheel ring 241. The friction columns 244 are in close contact with the side of the mounting frame 21 and are slidably connected. The two friction columns 244 are arranged in parallel and are centrally symmetrically distributed with the friction wheel ring 241 as the center. A spring 245 is slidably sleeved on the guide rod 243. The two ends of the spring 245 are fixedly connected to the friction column 244 and the corresponding end plate 242, respectively.

[0036] An anchor mechanism 2 is equipped with a variable tension mechanism 5 at its bottom. The variable tension mechanism 5 includes a horizontal plate 51 fixed to the bottom of the mounting frame 21. Two columns 54 are fixedly installed at the bottom of the horizontal plate 51. The telescopic mechanisms 55 on the two columns 54 are arranged in opposite directions and staggered. Wheel frames 56 are fixedly installed at the ends of the multiple telescopic mechanisms 55. Guide wheels 57 are rotatably installed on the wheel frames 56. Cable 23 passes through the horizontal plate 51 and passes around the multiple guide wheels 57 in sequence. Two guide wheels 57 are rotatably installed on the wheel frame 56 at the bottom. Cable 23 passes between the two guide wheels 57 and bends continuously after passing around the multiple guide wheels 57.

[0037] A pair of roller shafts 2 53 and a pair of roller shafts 1 52 are rotatably mounted on the top of the horizontal plate 51. Roller shafts 1 52 are located above roller shafts 2 53, and roller shafts 1 52 and roller shafts 2 53 are vertically distributed.

[0038] A circular hole 511 is provided on the horizontal plate 51 for the cable 23 to pass through.

[0039] The telescopic mechanism 55 includes a rectangular box 551 that passes through and is fixedly connected to the column 54. A rectangular column 553 is slidably installed through the rectangular box 551 on the side near the first cable 23. One end of the rectangular column 553 extending outside the rectangular box 551 is fixedly connected to the corresponding wheel frame 56. A rectangular piston 552 that is slidably connected to the inner wall of the rectangular box 551 is fixedly installed at one end of the rectangular column 553 inside the rectangular box 551. A second spring 554 is slidably sleeved on the rectangular column 553. The two ends of the second spring 554 are fixedly connected to the rectangular piston 552 and the inner wall of the rectangular box 551, respectively.

[0040] Two fine guide holes 555 are provided on one side of the rectangular box 551, and the rectangular piston 552 is located between the two fine guide holes 555.

[0041] Furthermore, since the rectangular box 551 is connected to the outside through two fine guide holes 555, when the rectangular column 553 is subjected to a rapid pushing or pulling force, the exchange flow of water inside and outside the rectangular box 551 through the two fine guide holes 555 is slow, making it difficult for the rectangular column 553 to move. However, when the rectangular column 553 is subjected to a slow pushing or pulling force, the water inside and outside the rectangular box 551 can exchange and flow through the two fine guide holes 555 in a timely manner, allowing the rectangular column 553 to move smoothly.

[0042] Furthermore, when the ends of cable 23 within the variable tension mechanism 5 are subjected to a rapid tension, the external force applied to the guide wheel 57 is too fast. At this time, because the exchange speed of external water and water within spring 2 554 through the two fine guide holes 555 is relatively slow, spring 2 554 will be unable to move within the rectangular box 551. This will prevent the rectangular column 553 from moving relative to the rectangular box 551, ultimately causing the ends of cable 23 within the variable tension mechanism 5 to... The cable 23 will not deform. This ensures that when the protective mechanism 1 rises rapidly with the water level, the change in position between the winding drum 22 and the ground anchor 4 is equivalent to the length of the cable 23 unwound from the winding drum 22. When the position of the protective mechanism 1 falls rapidly with the water level, the two guide wheels 57 on the bottom wheel frame 56 limit the cable 23, ensuring that the part of the cable 23 within the variable tensioning mechanism 5 will not become loose.

[0043] In this embodiment: During use, the entire device is placed in water. Under the action of the float ring 12, the entire protective mechanism 1 will float on the water surface. Then, the anchor 4 is released, allowing the anchor 4 to sink to the bottom under gravity. Figures 3-5 As shown, during the sinking of the ground anchor 4, the winding drum 22 will rotate counterclockwise and continuously unwind the cable 23. During this process, the friction column 244 located on the upper side of the torsion mechanism 24 will be driven from the right side to the left side by the friction wheel ring 241, and the friction column 244 located on the lower side of the torsion mechanism 24 will be driven from the left side to the right side by the friction wheel ring 241. During this process, the two springs 245 will be stretched.

[0044] like Figures 3-5 As shown, the friction between the friction ring 241 and the two guide rods 243 enables the winding drum 22 to rotate counterclockwise at a uniform speed, thereby preventing the anchor 4 from falling too fast and causing the cable 23 wrapped on the winding drum 22 to become tangled. Ultimately, after the anchor 4 touches the bottom, the two stretched springs 245 can apply a clockwise torsional force to the friction ring 241 through the corresponding friction column 244 under the reset elastic force. Finally, after the anchor 4 touches the bottom, the cable 23 between the winding drum 22 and the anchor 4 can remain taut.

[0045] After the ground anchor 4 touches the bottom, the prism 7 is passed through the first winding drum 22 and the two second winding drums 32. At this time, the float 34 in the reset mechanism 3 can straighten the second cable 35 between the second winding drum 32 and the float 34 under the action of buoyancy. Subsequently, floating plants can be planted in the cylindrical protective net 14. The float ring 12 is used to provide buoyancy for other components except the ground anchor 4. When planting floating plants, the other components are submerged in water, and only the float ring 12 itself is attached to the water surface or partially submerged in water. After the ground anchor 4 touches the bottom, only vertical tension can pull it up. When it is subjected to non-vertical tension, it will hook the bottom soil and gravel and will not shift. Moreover, the ground anchor 4 has a certain weight, and it cannot be pulled up by the buoyancy of the float ring 12 alone.

[0046] When the water level changes slowly, the entire protective mechanism 1 and the mounting frame 21 rise and fall simultaneously. Due to the buoyancy of the two floats 34, the two winding drums 32 and the prism 7 are difficult to rotate. At this time, the increased distance between the winding drum 22 and the ground anchor 4 allows the bent portion of the cable 23 at the variable tension mechanism 5 to be straightened when the water level rises and to bend more when the water level falls. This ensures that the protective mechanism 1 remains in a constant position relative to the ground anchor 4 as the water level changes slowly, preventing the protective mechanism 1 from shifting around when the water level changes.

[0047] In windy weather or when a ship passes by rapidly causing violent water level fluctuations, the rapid lifting and lowering speed of the protective mechanism 1 may prevent the various telescopic mechanisms 55 on the variable tensioning mechanism 5 from being stretched or compressed. Subsequently, as the protective mechanism 1 rises rapidly with the water level, such as... Figures 3-5 As shown, cable 23 will drive winding drum 22 to rotate counterclockwise. Winding drum 22 will then drive two winding drums 32 to rotate counterclockwise via prism 7. The counterclockwise rotation of winding drums 32 will drive buoy 34 to move down and submerge in the water via winding cable 35. Then, when the water level drops rapidly, the two buoys 34 will rise. When the two buoys 34 rise, they will drive prism 7 to rotate clockwise via winding drum 32. Prism 7 will then drive winding drum 22 to rotate clockwise. The clockwise rotation of winding drum 22 can wind up the excess cable 23, thereby ensuring that the position of the protective mechanism 1 relative to the ground anchor 4 remains unchanged when the water level is reset. This ensures that the protective mechanism 1 will not shift in different directions when the water level rises rapidly and then resets.

[0048] As the protective mechanism 1 descends rapidly with the water level, the previously taut cable 23, located between the take-up drum 22 and the ground anchor 4, will loosen. Then, as the protective mechanism 1 rises rapidly with the water level, the previously loosened cable 23 will tighten again. The position of the protective mechanism 1 relative to the ground anchor 4 remains unchanged, ensuring that the protective mechanism 1 will not shift in different directions when the water level drops rapidly and then resets. During this process, because a pair of rollers 52 and a pair of rollers 53 are in contact with the cable 23 between the horizontal plate 51 and the take-up drum 22, it can be ensured that the cable 23 wound on the take-up drum 22 will not come loose.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
