Description

Technical Field

[0001] The present invention relates to the technical field of ecological floating beds, and specifically to an ecological floating bed for ecological environment protection. Background Art

[0002] Ecological floating islands, also known as artificial floating beds, ecological floating beds, etc. It is a type of artificial floating island. For eutrophic water quality, using the principles of ecological engineering to degrade COD, nitrogen, and phosphorus in the water. It takes aquatic plants as the main body, applies the principle of soilless cultivation technology, uses polymer materials, etc. as carriers and substrates, and applies the symbiotic relationship between species to make full use of the water space ecological niche and nutrient ecological niche, thereby establishing an efficient artificial ecological system to reduce the pollution load in the water. It can greatly improve the water transparency, and at the same time, the water quality indicators are effectively improved, especially having a good inhibitory effect on algae. The most important effect of ecological floating islands on water purification is to use the roots of plants to absorb eutrophic substances in the water, such as total phosphorus, ammonia nitrogen, organic matter, etc., so that the nutrients in the water are transferred, reducing the phenomena of water body stench and eutrophication caused by water body enclosure or insufficient self-circulation.

[0003] The structure of an ecological floating bed usually includes three parts: a floating body, a planting basket, and aquatic plants. The floating body is the foundation of the floating island, generally made of lightweight materials such as plastics and foams to provide buoyancy support. The planting basket is used to fix the roots of plants, usually made of plastic or fiber materials, with good air permeability and water retention. Plants are planted in the planting basket, absorbing nutrients in the water through their roots, and playing the role of purifying water quality and beautifying the environment. The planting medium used in the ecological floating bed usually selects large-particle environmental protection materials, which not only provide a growth basis for plants but also can purify water quality to a certain extent, such as lightweight ceramsite, polymer materials, etc. In addition, to enhance the stability and durability of the floating island, some connecting components and fixing devices may be added, such as ropes, anchors, etc.

[0004] In the prior art, the outer wall of the planting basket in the ecological floating bed usually has notches to facilitate water entering the planting basket and using aquatic plants to purify the water. The roots of plants grow in a scattered manner, and the roots will pass through the gaps in the planting medium and the notches of the planting basket, and the growing roots extend into the water. If the water flow is too fast due to environmental factors, the growing roots will be bent under the influence of the water flow, and the plant roots are prone to breakage due to being unable to withstand greater water flow forces for a long time.

[0005] In view of the above problems, there is an urgent need for innovative design based on the original ecological floating bed. Summary of the Invention

[0006] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide an ecological floating bed for ecological environment protection to solve the problem that the too-fast water flow easily causes damage to the plant roots as proposed in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solution: An ecological floating bed for ecological environment protection includes a floating board and placement grooves evenly formed inside it, and further includes a planting mechanism evenly arranged in the placement grooves for planting aquatic plants, an elastic member arranged on the planting mechanism for slowing down the flow rate of water entering the planting mechanism, a guide plate arranged at equal angles outside the elastic member for reducing the impact of water flow on the roots of aquatic plants, and an auxiliary driving mechanism arranged at both ends of the guide plate for driving the guide plate to rotate synchronously in the same direction and the elastic member to adaptively stretch and deform. The elastic member is arranged as a longitudinally distributed spiral strip structure.

[0008] Preferably, the planting mechanism includes a first fixing plate fixed to the inner wall of the placement groove. A planting cylinder is fixed at the center of the first fixing plate, and water inlet grooves are evenly formed on the outer wall of the planting cylinder.

[0009] Preferably, the first fixing plate is arranged as an annular structure, and the top of the planting cylinder is provided with an opening, and the water inlet grooves are arranged as longitudinally distributed strip structures.

[0010] Preferably, the top end of the elastic member is fixed to the bottom of the first fixing plate, and the elastic member fits against the outer wall of the planting cylinder.

[0011] Preferably, the auxiliary driving mechanism includes a second fixing plate fixed to the outer wall of the lower end of the planting cylinder. A rotating shaft is rotatably connected at equal angles between the first fixing plate and the second fixing plate, and the guide plate is correspondingly fixed to the outer wall of the rotating shaft. A gear set is arranged between the first fixing plate and the upper end of the rotating shaft, and a guiding component is arranged between the second fixing plate and the lower end of the rotating shaft.

[0012] Preferably, the gear set includes a small gear respectively fixed to the outer wall of the upper end of the rotating shaft, and a toothed ring is arranged outside the small gear and meshes with it.

[0013] Preferably, the guiding component includes fixing disks respectively fixed to the outer wall of the lower end of the rotating shaft. A sliding ring slidably matched with the planting cylinder is fixed to the bottom end of the elastic member. Guide plates corresponding to the fixing disks are evenly fixed to the outer wall of the sliding ring, and guiding columns located at the bottom of the guide plates are fixed to the top of the fixing disks.

[0014] Preferably, the guide plates are inclined on the outer wall of the sliding ring, and the top of the guiding column is in contact with the bottom surface of one end of the guide plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention is provided with a flow deflector. When the water flow velocity is relatively fast, due to the equal-angle setting of the flow deflector, no matter which direction the water flow is facing, it will push the flow deflector in the water flow direction to rotate. Under the action of the small gear and the toothed ring, the flow deflectors all rotate synchronously, and there is still a gap between two adjacent groups of flow deflectors after rotation. In the water flow direction, the flow deflector plays a role in guiding and dispersing the water flow, effectively reducing the impact damage directly caused by the water flow on the plant roots; (2) The present invention is provided with a flow deflector and an elastic member with a spiral strip structure. When the water flow velocity is relatively fast, the gap after the rotation of the flow deflector and the gap after the deformation of the elastic member can cause part of the water flow to be diverted and flow towards the planting cylinder. The flow velocity of this part of the water flow is reduced, increasing the residence time of the water body entering the planting cylinder, thereby increasing the absorption and degradation of pollutants and nutrients in the water body by plants and microorganisms.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 7, the present invention provides a technical solution: an ecological floating bed for ecological environment protection, including a floating board 1 and placing grooves 2 evenly formed inside it, and further including a planting mechanism uniformly arranged in the placing grooves 2 for planting aquatic plants, an elastic member 5 arranged on the planting mechanism for slowing down the flow rate of water entering the planting mechanism, a guide plate 8 arranged outside the elastic member 5 at equal angles for reducing the impact of water flow on the roots of aquatic plants, and an auxiliary driving mechanism arranged at both ends of the guide plate 8 for driving the guide plate 8 to rotate synchronously and in the same direction and for the elastic member 5 to adaptively expand and contract and deform. The elastic member 5 is arranged in a longitudinally distributed spiral strip structure.

[0020] It should be noted that when the floating board 1 is placed on the water surface, it will be fixed in the water body by a fixing system to prevent it from drifting. The fixing system is a prior art. The planting mechanism can be used to plant aquatic plants. The elastic member 5 can be made of elastic metal material. The spiral strip structure can enable the elastic member 5 to change its gap due to the change in length during expansion and contraction and has the ability to recover from deformation. In the initial state, the guide plate 8 and the planting cylinder 4 are arranged at an angle close to 45 degrees. The auxiliary driving mechanism can drive the elastic member 5 to adjust the gap after the guide plate 8 rotates due to water flow.

[0021] The planting mechanism includes a first fixing plate 3 fixed to the inner wall of the placing groove 2. A planting cylinder 4 is fixed at the center of the first fixing plate 3. Water inlet grooves 401 are evenly formed on the outer wall of the planting cylinder 4 at equal angles.

[0022] The first fixing plate 3 is arranged in an annular structure, and the top of the planting cylinder 4 is provided with an opening, and the water inlet grooves 401 are arranged in a longitudinally distributed strip structure.

[0023] It should be noted that when the plant roots grow dispersedly, they can adaptively pass through the water inlet grooves 401 on the planting cylinder 4 and the gaps of the elastic member 5. The longer plant roots will adaptively grow between the guide plates 8. The gap after the elastic member 5 contracts ensures that the extended plant roots will not be broken.

[0024] The top end of the elastic member 5 is fixed to the bottom of the first fixing plate 3, and the elastic member 5 is attached to the outer wall of the planting cylinder 4.

[0025] It should be noted that after pushing the bottom of the elastic member 5, the top end of the elastic member 5 is fixed to the first fixing plate 3. While the elastic member 5 shortens and the gap decreases, the inner side wall moves along the outer wall of the planting cylinder 4.

[0026] The auxiliary driving mechanism includes a second fixing plate 6 fixed to the outer wall of the lower end of the planting cylinder 4. A rotating shaft 7 is rotatably connected between the first fixing plate 3 and the second fixing plate 6 at equal angles. The guide plate 8 is correspondingly fixed to the outer wall of the rotating shaft 7. A gear set is arranged between the upper end of the first fixing plate 3 and the rotating shaft 7, and a guiding component is arranged between the lower end of the second fixing plate 6 and the rotating shaft 7.

[0027] The gear set includes a small gear 9 fixedly arranged on the outer wall of the upper end of the rotating shaft 7, and a toothed ring 10 meshing with the small gear 9 is arranged outside the small gear 9.

[0028] The guiding assembly includes a fixed disk 11 fixedly arranged on the outer wall of the lower end of the rotating shaft 7. A sliding ring 12 that is slidably matched with the planting cylinder 4 is fixed to the bottom end of the elastic member 5. Guide plates 13 corresponding to the fixed disk 11 are fixedly arranged at equal angles on the outer wall of the sliding ring 12. Guide posts 14 located at the bottom of the guide plates 13 are fixed to the top of the fixed disk 11.

[0029] The guide plates 13 are inclinedly arranged on the outer wall of the sliding ring 12, and the top of the guide post 14 is in contact with the bottom surface of one end of the guide plate 13.

[0030] It should be noted that when the rotating shaft 7 rotates following the flow guide plate 8, the upper end of the rotating shaft 7 drives the small gear 9 on the outer wall to rotate. Since each group of small gears 9 meshes with the toothed ring 10, when one group of small gears 9 rotates, the toothed ring 10 is utilized to drive other small gears 9 to rotate synchronously in the same direction. The lower end of the rotating shaft 7 drives the fixed disk 11 to rotate by a certain angle, and the fixed disk 11 drives the guide post 14 at the top to rotate. Since the guide plates 13 are arranged at an inclined angle, when the guide post 14 rotates, its top can push the guide plate 13 to move upward, so that the sliding ring 12 slides upward on the outer wall of the planting cylinder 4. The sliding ring 12 squeezes the elastic member 5 with a spiral strip structure to contract, so that the gap of the elastic member 5 decreases. The elastic force limitation of the elastic member 5 enables the elastic member 5 to still have a certain gap when being squeezed.

[0031] Working principle: First, when using this ecological floating bed, it floats on the water surface under the action of the floating plate 1. The inside of the planting cylinder 4 is filled with a planting medium. Aquatic plants are planted in the planting cylinder 4 by using the planting medium, and the roots of the aquatic plants are immersed in the water to purify the water body, thereby protecting the ecological environment.

[0032] Then, when the water flow velocity is normal, the thrust of the water flow is small. Under the elastic limiting action of the elastic member 5, the flow guide plate 8 will not rotate due to the thrust of the water flow, and the water body can normally enter the planting cylinder 4 to be purified by the aquatic plants.

[0033] When the water flow velocity is relatively fast, the thrust of the water flow is greater than the elastic force of the elastic member 5 at this time. Due to the angular setting of the flow deflector 8 and other components, and the flow deflector 8 and the planting cylinder 4 are arranged at an angle close to 45 degrees in the initial state. No matter which direction the water flow is facing, it will push the flow deflector 8 in the water flow direction to rotate. Among them, the flow deflector 8 with the largest contact surface with the water flow direction receives the greatest thrust. This group of flow deflectors 8 drives the rotation of the rotating shaft 7, and the upper end of the rotating shaft 7 drives the small gear 9 on the outer wall to rotate. Since each group of small gears 9 meshes with the toothed ring 10, when one group of small gears 9 rotates, the toothed ring 10 is used to drive other small gears 9 to rotate synchronously in the same direction. The lower end of the rotating shaft 7 drives the fixed disk 11 to rotate by a certain angle, and the fixed disk 11 drives the guide post 14 at the top to rotate. Since the guide plate 13 is arranged at an inclined angle, when the guide post 14 rotates, its top can push the guide plate 13 to move upward, so that the sliding ring 12 slides upward on the outer wall of the planting cylinder 4. The sliding ring 12 squeezes the elastic member 5 with a spiral structure to contract, reducing the gap of the elastic member 5. And the elastic force limit of the elastic member 5 makes the elastic member 5 still have a certain gap when being squeezed. And the plant roots can adaptively penetrate through the water inlet groove 401 on the planting cylinder 4 and the gap of the elastic member 5 during decentralized growth. The longer plant roots can adaptively grow between the flow deflectors 8. The gap after the contraction of the elastic member 5 ensures that the extended plant roots will not be broken.

[0034] Finally, in the state where the water flow velocity is relatively fast as described above, on the one hand, the flow deflector 8 rotates synchronously with the water flow. There is still a gap between two adjacent groups of flow deflectors 8 after rotation. In the water flow direction, the flow deflector 8 plays a role in guiding and dispersing the water flow, effectively reducing the impact damage directly caused by the water flow on the plant roots. On the other hand, the gap after the rotation of the flow deflector 8 and the gap after the deformation of the elastic member 5 can make part of the water flow shunt and flow towards the planting cylinder 4. The flow velocity of this part of the water flow is reduced, increasing the residence time of the water body entering the planting cylinder 4. Thus, it increases the absorption and degradation of pollutants and nutrients in the water body by plants and microorganisms. Until the water flow returns to normal, under the action of the deformation reset of the elastic member 5, the floating plate 1 and the elastic member 5 both return to the initial state.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
