Description

Technical Field

[0001] The present invention relates to the technical field of river pollution control, and in particular to a river pollution control floating island and a use method thereof. Background Art

[0002] A river channel is the route through which water flows, usually referring to a navigable waterway. With the influence of human life or the development of the ecological environment within the river channel, garbage is easily accumulated or eutrophication occurs. In order to manage the river channel, ecological floating islands have comprehensive functions such as purifying water quality, creating living space for organisms, improving landscapes, and eliminating waves. They are widely used in closed waters such as reservoirs with large water level fluctuations, lakes and swamps where it is difficult to restore aquatic plant belts on the shore due to waves, or ponds with landscape requirements. Floating islands mainly refer to artificial water plant planting platforms built for water purification, which utilize eutrophic substances such as nitrogen, phosphorus, and organic matter absorbed during plant growth. It is one of the commonly used means of water ecological restoration.

[0003] Most of the existing floating islands are ecological floating islands, which absorb nutrients from the river channel through easy-to-survive aquatic plants. Since these aquatic plants grow quickly and have well-developed root systems, the roots gradually become longer as they grow.

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] like Figures 1 to 7As shown, the floating island for river pollution control of the present invention includes a floating base 1, and a plurality of buffer mechanisms 2 are installed along the circumference of the floating base 1. A power storage mechanism 8 is connected between the buffer mechanism 2 and the floating base 1. The power storage mechanism 8 is installed inside the floating base 1, and the end of the power storage mechanism 8 is connected to the buffer mechanism 2; a cutting mechanism 19 is installed at the bottom of the floating base 1.

[0033] like Figure 1 As shown, a plurality of installation grooves are provided in the floating base 1 , and an installation frame 101 is fixed in each installation groove, and the aquatic plants are fixed by the installation frame 101 .

[0034] like Figure 3 and Figure 4 As shown, the buffer mechanism 2 includes a plurality of sleeve rods 3 fixedly arranged on the outer side of the floating base 1, each sleeve rod 3 is slidably connected with a buffer rod 4, and a buffer spring 7 is respectively connected between one end of the buffer rod 4 located in the sleeve rod 3 and the floating base 1 on the corresponding side, and the other ends of the plurality of buffer rods 4 located on the same side are commonly connected with a buffer plate 5, and a plurality of buffer air bags 6 are installed on the other side of the buffer plate 5. A mobile damping mechanism is provided between one end of the buffer rod 4 located in the sleeve rod 3 and the inner surface of the sleeve rod 3, and the buffer plate 5 and the buffer air bag 6 are installed by the sleeve rod 3 in conjunction with the buffer spring 7 and the buffer rod 4, and the buffer air bag 6 provides buoyancy to the floating base 1, and the elastic force of the buffer spring 7, the sleeve rod 3, the buffer rod 4 and the mobile damping mechanism are used to buffer the water flow impact and debris impact force on the floating base 1, thereby protecting the floating base 1 and extending the service life of the floating base 1. A sealing ring is fixedly arranged at one end of the inner surface of the sleeve rod 3 away from the floating base 1, and the sealing ring is in close contact with the outer surface of the buffer rod 4. The sealing ring seals the gap between the sleeve rod 3 and the buffer rod 4 to prevent external water from entering the sleeve rod 3 and affecting the normal use of the buffer mechanism 2. One end of the transmission rod 10 away from the rotating disk 13 is respectively fixedly arranged on the surface of the corresponding buffer plate 5. When the buffer airbag 6 and the buffer plate 5 are impacted and moved, the transmission rod 10 can be driven to move.

[0035] like Figure 3 and Figure 4As shown, the power storage mechanism 8 includes a rotating rod 9 rotatably connected inside the floating base 1, a coil spring 15 and a rotating disk 13 are coaxially sleeved on the upper part of the rotating rod 9, the rotating disk 13 is located below the coil spring 15, the inner end of the coil spring 15 is fixed on the circumferential surface of the rotating rod 9, and the outer end of the coil spring 15 is fixed on the inner surface of the floating base 1. The circumferential surface of the rotating rod 9 is coaxially rotatably connected with the rotating disk 13 through a transmission one-way bearing, and a toothed disk 14 is coaxially fixed on the circumferential surface of the rotating disk 13. A plurality of transmission rods 10 are arranged in a circumferential array inside the floating base 1. In this embodiment, four transmission rods 10 are provided, and the four transmission rods 10 are slidably connected inside the floating base 1. The ends of the transmission rods 10 close to the rotating disk 13 are rotatably connected with a transmission toothed plate 11 through a torsion spring, and the outer surfaces of the transmission toothed plate 11 are in close contact with the circumferential surface of the rotating disk 13. The surface of the transmission toothed plate 11 close to the rotating disk 13 is rotatably connected with a plurality of teeth 12 through a torsion spring, and the teeth 12 are meshed with the toothed disk 14. When the transmission rod 10 moves toward the direction approaching the rotating rod 9, it can drive the transmission tooth plate 11 to move, and through the teeth 12, it can drive the toothed plate 14, the rotating plate 13 and the rotating rod 9 to rotate, thereby driving the inner end of the coil spring 15 to rotate to reel in and store force. When the transmission rod 10 moves toward the direction away from the rotating rod 9, since the teeth 12 are connected to the transmission tooth plate 11 through the torsion spring, the rotating rod 9 will not be driven to rotate when the transmission rod 10 is reset, thereby effectively achieving the purpose of storing force.

[0036] A clamping wheel 16 is coaxially fixed to the lower part of the rotating rod 9. Figure 7 As shown, a plurality of compression springs 17 are fixedly arranged at the bottom of the floating base 1. In this embodiment, two compression springs 17 are symmetrically arranged on both sides of the card wheel 16. The two compression springs 17 are fixedly arranged with a latching tooth 18 at one end close to the card wheel 16. The latching tooth 18 meshes with the card wheel 16. The contact surface between the latching tooth 18 and the card wheel 16 is an inclined surface. The inclined surfaces of the latching teeth 18 on both sides have different inclinations. When the rotating rod 9 rotates forward, the card wheel 16 is driven to rotate. During the rotation of the card wheel 16, the latching tooth 18 can be squeezed to compress the compression spring 17. When the rotating rod 9 and the card wheel 16 stop rotating, the elastic force of the compression spring 17 drives the latching tooth 18 to reset, so that the latching tooth 18 meshes with the card wheel 16, limits the rotating rod 9, and prevents the rotating rod 9 from rotating, so that the coil spring 15 can be wound up to store power. When the coil spring 15 is rolled up to a certain extent, the elastic force of the coil spring 15 drives the rotating rod 9 to rotate in the opposite direction. Since the inclined surfaces of the latching teeth 18 on both sides have different inclinations, the rotating rod 9 often needs a large force to rotate in the opposite direction.

[0037] like Figure 5As shown, one end of the rotating rod 9 away from the coil spring 15 is coaxially connected to the upper end of the rotating shaft 20 through a driven one-way bearing, and the transmission one-way bearing and the driven one-way bearing rotate in opposite directions. Through the setting of the transmission one-way bearing, when the turntable 13 rotates forward, it can drive the rotating rod 9 to rotate forward, and when the rotating rod 9 rotates reversely, it will not drive the turntable 13 to rotate reversely. Through the setting of the driven one-way bearing, when the turntable 13 rotates reversely, it can drive the rotating rod 9 to rotate reversely, and when the rotating rod 9 rotates forward, it will not drive the turntable 13 to rotate forward.

[0038] like Figure 6 and Figure 7 As shown, the cutting mechanism 19 includes a rotating shaft 20 and a rotating ring 24 which are rotatably connected to the inner bottom of the floating base 1. The rotating shaft 20 and the rotating ring 24 are coaxially installed. A rotating plate 21 is fixedly arranged at the bottom of the rotating shaft 20. The upper surface of the rotating plate 21 is coaxially rotatably connected to the bottom of the rotating ring 24. The circumferential surfaces of the rotating plate 21 and the rotating ring 24 are respectively fixedly arranged with upper and lower groups of cutting blades 25, and the blades of the upper and lower groups of cutting blades 25 are in opposite directions. An inner gear ring 22 is coaxially fixedly arranged on the circumferential surface of the rotating shaft 20, and an outer gear ring 26 is coaxially fixedly arranged on the inner surface of the rotating ring 24. A gear 23 is meshed between the inner gear ring 22 and the outer gear ring 26. The gear 23 is rotatably connected to the inner bottom of the floating base 1. When the rotating shaft 20 rotates, it can drive the inner gear ring 22 to rotate, and the gear 23 drives the outer gear ring 26 to rotate, thereby driving the rotating ring 24 to rotate in the direction opposite to the direction of the rotating shaft 20. When the rotating shaft 20 rotates, the rotating plate 21 drives the lower group of cutting blades 25 to rotate forwardly, and when the rotating ring 24 rotates, it can drive the upper group of cutting blades 25 to rotate reversely. The two groups of cutting blades 25 rotating in opposite directions can cut off the plant roots to prevent the plant roots from growing too long.

[0039] A method for using a floating island for river pollution control comprises the following steps:

[0040] S1, installing the installation frame 101 inside the installation groove of the floating base 1, installing the aquatic plants through the installation frame 101, and placing the floating base 1 inside the river;

[0041] S2. The buffer mechanism 2 can buffer the impact of water flow and debris, thereby protecting the floating base 1 and extending the service life of the floating base 1;

[0042] S3, when the water flow impacts and the debris hits the buffer mechanism 2, it drives the power storage mechanism 8 to work and store power, and when the power storage mechanism 8 stores power to a certain extent, it drives the cutting mechanism 19 to work;

[0043] S4. The power storage mechanism 8 can drive the rotating shaft 20, the rotating plate 21 and the rotating ring 24 to rotate, thereby driving the upper and lower sets of cutting blades 25 to rotate in opposite directions to cut off the roots of aquatic plants.
