Description

Technical Field

[0001] The present invention relates to the technical field of lake water ecology, and particularly relates to a river and lake water ecological treatment device and method. Background Art

[0002] River and lake water is ecologically treated through aquatic green plants. In order to improve the purification efficiency and quality, in current ecological restoration projects, a technical means combining aeration and oxygenation with submerged plants is often adopted. The submerged plants are cultivated in rivers and lakes through cultivation trays and floating islands. Through continuous cultivation methods, the green plants can survive for a long time, achieving the purpose of continuous purification of rivers and lakes.

[0003] The existing submerged plant wading cultivation has the following defects: the plant roots are prone to overgrow and penetrate into the bottom mud, causing secondary pollution after rotting. Traditional manual root pruning is inefficient and damages the ecology. The mechanical structure is complex and the cleaning effect is poor. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a river and lake water ecological treatment device, including a floating hose, an aquatic green plant cultivation component, a linkage mechanism, and a root cutting module. An air supply pipe is provided on the side of the floating hose, and a floating body is provided on the bottom surface. The aquatic green plant cultivation component is arranged near the floating hose, and it includes a floating body base and a cultivation tray arranged on the top of the floating body base. The floating body base is flexibly connected to the floating hose and floats on the river and lake surface. The aquatic green plant cultivation component is provided with a planting hole penetrating through the cultivation tray and the floating body base. The linkage mechanism includes a driving seat sleeved on the air supply pipe and a driving rod connected to the driving seat to drive the driving seat to move relative to the floating body base. The air supply pipe is located at the bottom side of the aquatic green plant cultivation component. The root cutting module includes a saw blade installed on the driving seat, and the saw blade extends towards the bottom side of the cultivation tray. The air supply pipe is parallel to the upper side near the saw blade and is provided with air holes.

[0005] As a further preference, both ends of the floating hose are provided with sealing end caps, and a joint is installed on one of the sealing end caps.

[0006] As a further preference, there are at least two groups of aquatic green plant cultivation components symmetrically arranged on both sides of the floating hose. For a group on the same side, there are at least two places in the front and back. There are at least two groups of air supply pipes symmetrically arranged on both sides of the floating hose. A group of air supply pipes on the same side is composed of several unit pipes connected to the side of the floating hose. The bottom side of each aquatic green plant cultivation component corresponds to several unit pipes, and a saw blade installed on the driving seat is provided near each unit pipe.

[0007] As a further preference, the saw blade is inclined to the unit pipe, the saw blade and the unit pipe are arranged at intervals, saw blades are provided on both sides of the saw blade, and a gap is provided between the saw blades of adjacent two saw blades.

[0008] As a further preference, the unit pipe is split-type and is connected to the floating hose through a rotary joint, enabling the unit pipe to rotate.

[0009] As a further preference, multiple aeration holes are provided on the same unit pipe. Some of the aeration holes are opened upward relative to the floating body base, and some of the aeration holes face the upper surface of the saw blade.

[0010] As a further preference, the driving rod is composed of two split-type rods. One driving rod is connected to the driving seat on one side, and the other driving rod is connected to the driving seat on the other side. The linkage mechanism further includes a driving pair connected between the two driving rods and a driving disk driven on the driving pair. An oval hole is provided on the driving pair, and a driving eccentric shaft slidably fitted on the oval hole is provided on the driving disk. The driving disk is connected to the motor, and the motor is fixed on the floating body.

[0011] As a further preference, the floating hose, the aeration pipe, and the linkage mechanism are all made of corrosion-resistant HDPE plastic pipes, and the cultivation tray in the aquatic green plant cultivation component is an HDPE cultivation basket.

[0012] A method for river and lake water ecological treatment includes the following steps:

[0013] Step s01, plant screening: Select submerged plants (such as Vallisneria natans and Potamogeton distinctus) and emergent plants (Phragmites australis and Typha orientalis) and mix-plant them in the cultivation tray at a ratio of 3:1;

[0014] Step s02, floating pipe network layout: Connect both sides of the floating hose with a diameter of 200 mm to the aquatic green plant cultivation component through hemp ropes and put them on the lake surface, keeping a swing margin of 0.2 - 0.5 m, and then anchor the floating hose;

[0015] Step s03, micro-aeration control: Introduce gas into the floating hose and implement pulse aeration through the aeration pipe. The aeration intensity is 0.3 m 3 / (m·h), and the working cycle is aeration for 15 min / stop for 45 min; Use the 2 - 3 mm microbubbles generated by aeration to form an oxidation layer on the root surface;

[0016] Step s04: Real-time monitor the root growth rate through the fiber optic sensor. When the daily growth amount > 8 cm, trigger the cutting program, and the linkage mechanism drives the root cutting module to complete the cutting of the excess roots.

[0017] The beneficial effects of the present invention compared with the prior art are:

[0018] 1. The driving seat drives the saw blade to perform a reciprocating linear motion relative to the bottom of the floating base. This is equivalent to sawing the root system. The floating base is not fixed but is connected near the aeration pipe through flexible connectors such as hemp ropes and silicone dampers. Therefore, the floating base will sway relative to the aeration pipe due to the rippling of the lake surface. The cultivation tray is carried by the floating base and sways relative to the aeration pipe, which is equivalent to making the root system move relative to the saw blade. Therefore, when the saw blade cuts the root system, the relative motion makes the root system effectively lean towards the saw blade, thereby increasing the cutting range of the saw blade on the root system and improving the cutting quality. The saw blade moves away from the bottom of the floating base along with the aeration pipe. According to the growth habits of aquatic green plants, even if the saw blade trims the root system, it can still ensure that the root system has enough length at the bottom of the water, thus solving the problem that the plant root system is prone to overgrow and penetrate into the bottom mud, causing secondary pollution after rotting.

[0019] 2. The saw blade is arranged on the aeration pipe through the driving seat. The aeration pipe is led out by a floating hose and is horizontal in the water area at the bottom of the floating base. During the growth process of aquatic green plants, in addition to aerating and increasing oxygen to the root system and assisting the growth of green plants, the aeration pipe also plays a role in stably guiding the movement of the driving seat with the saw blade. Moreover, when the saw blade performs the sawing action, the aeration pipe also supplies gas to the root system, assisting the water flow to wash away the root system from the bottom. When the aeration is carried out, the gas flushes onto the interceptors of the root system, keeping the root system clean and preventing the saw blade from damaging the cutting edge during sawing.

Specific embodiments

[0027] The following will clearly and completely describe the above and other embodiments and advantages of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments.

[0028] In one embodiment, as Figures 1-6 shown:

[0029] This embodiment provides a river and lake water ecological governance device, including a floating hose 10, an aquatic green plant cultivation component 20, a linkage mechanism 30 and a root cutting module 40. An aeration pipe 101 is provided on the side of the floating hose 10, and a floating body 102 is provided on the bottom surface. The aquatic green plant cultivation component 20 is arranged on the near side of the floating hose 10, and includes a floating body base 210 and a cultivation tray 220 arranged on the top of the floating body base 210. The floating body base 210 is flexibly connected to the floating hose 10 and floats on the river and lake surface. Planting holes 230 penetrating through the cultivation tray 220 and the floating body base 210 are provided on the aquatic green plant cultivation component 20. The linkage mechanism 30 includes a drive seat 310 sleeved on the aeration pipe 101 and a drive rod 320 connected to the drive seat 310 to drive the drive seat 310 to move relative to the floating body base 210. The aeration pipe 101 is located at the bottom side of the aquatic green plant cultivation component 20. The root cutting module 40 includes a saw blade 410 installed on the drive seat 310, and the saw blade 410 extends to the bottom side of the cultivation tray 220. The aeration pipe 101 is parallel to and above the vicinity of the saw blade 410 and is provided with aeration holes 103.

[0030] In this embodiment, the driving rod 320 drives the driving seat 310, and the driving seat 310 drives the saw blade 410 to perform reciprocating linear motion relative to the bottom of the floating base 210. During the growth of aquatic green plants, their roots are underwater and grow toward the mud at the bottom of the lake. In order to prevent the roots from directly penetrating into the mud and being contaminated, when the saw blade 410 performs reciprocating linear motion relative to the bottom of the floating base 210, it is equivalent to completing sawing for the roots. The floating base 210 is not fixed, but is connected. A flexible connector such as a hemp rope, a silicone damper, etc. is connected near the aeration tube 101, so the floating base 210 will shake relative to the aeration tube 101 due to the ripples of the lake surface, and the floating base 210 will shake the cultivation plate 220 relative to the aeration tube 101, which is equivalent to making the root system move relative to the saw blade 410. Therefore, when the saw blade 410 cuts the root system, the root system is effectively moved toward the saw blade 410 through relative movement, thereby increasing the cutting range of the saw blade 410 for the root system and improving the cutting quality. The saw blade 410 is away from the bottom of the floating base 210 along with the aeration tube 101. According to the growth habits of aquatic green plants, even if the saw blade 410 trims the root system, it can still ensure that the root system has enough length to be located at the bottom of the water, thereby solving the problem that the plant root system is prone to excessive growth and penetrate into the bottom mud, causing secondary pollution after rotting.

[0031] In this embodiment, the saw blade 410 is arranged on the aeration pipe 101 through the driving seat 310. The aeration pipe 101 is led out from the floating hose 10 and is horizontally placed in the bottom water area of ​​the floating base 210. During the growth of aquatic green plants, the aeration pipe 101 not only aerates and oxygenates the root system and assists the growth of green plants, but also plays a role in smoothly guiding the movement of the driving seat 310 with the saw blade 410. Moreover, when the saw blade 410 is sawing, the aeration pipe 101 also provides gas to the root system, assisting the water flow to flush the root system from the bottom. During aeration, the gas rushes into the interception object of the root system, keeping the root system clean and avoiding damage to the cutting edge when the saw blade 410 is sawing. The aeration tube 101 not only plays an aeration and growth role for the root system, but also utilizes its lateral horizontal extension to sleeve the saw blade 410 on the aeration tube 101 through a sleeve to form a sliding fit relationship. All the sleeves are connected to the drive seat 310 together, so that all the saw blades 410 can achieve synchronous sawing action with the drive seat 310. The movement degree of the saw blade 410 is not large, and it only needs to meet the need to cut off the excess root system. The distance between the two aeration holes 103 meets the movement degree of the saw blade 410. Therefore, when the saw blade 410 slides on the aeration tube 101, it will not cause obstacles or blockage to the aeration holes 103 on the aeration tube 101.

[0032] Both ends of the floating hose 10 are provided with sealed end caps 104, and a joint 105 for connecting an aerator is installed on one of the sealed end caps 104. The floating hose 10 has a hollow structure and is lightweight. Under the floating action of the bottom floating body base 210, it can float reasonably on the lake surface. The joint 105 is connected to the aerator through a hose to supply gas. When supplying gas, all the aeration pipes 101 aerate the lake water through all the aeration holes 103. When shearing, the cut roots are washed away by the water flow, and when not shearing, oxygen is supplied to the roots and flocs are cleaned, improving functionality.

[0033] As Figure 1 , Figure 3 and Figure 5 shown, the aquatic green plant cultivation components 20 are at least two groups symmetrically arranged on both sides of the floating hose 10. One group of aquatic green plant cultivation components 20 on the same side is at least two in the front and back. The aeration pipes 101 are at least two groups symmetrically arranged on both sides of the floating hose 10. One group of aeration pipes 101 on the same side is composed of several unit pipes 106 connected to the side of the floating hose 10. The bottom side of each aquatic green plant cultivation component 20 corresponds to several unit pipes 106, and a saw blade 410 installed on the driving seat 310 is provided near each unit pipe 106. There is a gap between two unit pipes 106, and there is a gap between two saw blades 410. In most cases, the roots grow downward along the gap, which makes the roots within the sawing range of the saw blade 410 and also within the aeration range of the unit pipe 106. When the roots grow to the saw blade 410, the motor is started to drive the driving pair 330, the driving pair 330 drives the driving rod 320, the driving rod 320 drives the driving seat 310, and the driving seat 310 drives all the saw blades 410 to perform sawing actions, quickly cutting off the excess roots. The roots are near the saw blades between the two saw blades 410, so the cutting efficiency is improved during sawing. During the sawing process, these unit pipes 106 aerate outward through the aeration holes 103. Since there are multiple aeration holes 103 on the same unit pipe 106, and some aeration holes 103 are opened upward relative to the floating body base 210, and some aeration holes 103 face the upper surface of the saw blade 410, part of the gas emitted acts on the roots, and the other part acts on the saw blade 410. The gas acting on the roots washes away the cut roots, and the gas acting on the saw blade 410 cleans the impurities falling on the surface during sawing. These unit pipes 106 aerate outward through the aeration holes 103 in the normal state (when not sawing) to supply oxygen to the roots, which is beneficial to the growth of green plants.

[0034] The saw blade 410 is inclined to the unit pipe 106, the saw blade 410 and the unit pipe 106 are arranged at intervals, saw blades are provided on both sides of the saw strip 530, and there is a gap between the saw blades of two adjacent saw blades 410.

[0035] As Figure 3 , Figure 4 and Figure 6As shown in the figure, the driving rod 320 is divided into two parts. One driving rod 320 is connected to one side driving seat 310, and the other driving rod 320 is connected to the other side driving seat 310. The linkage mechanism 30 further includes a driving pair 330 connected between the two driving rods 320 and a driving disk 340 transmitted on the driving pair 330. An oval hole 350 is formed on the driving pair 330, and a driving eccentric shaft 360 slidably fitted on the oval hole 350 is provided on the driving disk 340. The driving disk 340 is connected to the motor, and the motor is fixed on the floating body 102 through a fixing frame. Two guiding seats are installed on the floating body 102, and the two driving rods 320 are slidably oriented on the two guiding seats.

[0036] In this embodiment, during actual assembly, an optical fiber sensor is set on the device. To achieve remote management, the optical fiber sensor is connected to a terminal device, and the root growth rate is monitored in real time through the optical fiber sensor. When the daily growth amount > 8 cm, the cutting program is triggered, the motor starts and drives the driving eccentric shaft 360 to rotate relative to the oval hole 350. According to the mechanical transmission principle, it can be known that the driving pair 330 will drive the two driving rods 320 to perform reciprocating linear motion. The two driving rods 320 drive the two driving seats 310 to perform reciprocating linear motion, and the two driving seats 310 drive the saw blades 410 on both sides to perform reciprocating linear motion along the corresponding unit pipe 106, and at the same time cut and trim the redundant roots growing from the gap between the two saw blades 410 to the bottom. With the impact of water flow and the aeration effect of the unit pipe 106, the cut root parts are washed away by the water flow, and the roots are far away from the silt and will not be polluted.

[0037] The floating hose 10, the aeration pipe 101, and the linkage mechanism 30 are all made of corrosion-resistant HDPE plastic pipes. The cultivation tray 220 in the aquatic green plant cultivation component 20 is an HDPE cultivation basket, which is relatively light in weight. In addition, by setting the floating body 102 at the bottom of the floating hose 10 and the floating body base 210 at the bottom of the aquatic green plant cultivation component 20, the floating hose 10 and the aquatic green plant cultivation component 20 can effectively float on the lake surface, and have enough buoyancy to limit other components within the water depth range.

[0038] A method for river and lake water ecological governance includes the following steps:

[0039] Step s01, plant screening: Select submerged plants such as (Vallisneria natans, Potamogeton distinctus) and emergent plants Phragmites australis, Typha orientalis and mix-plant them in the cultivation tray 220 at a ratio of 3:1;

[0040] Step s02: Deployment of floating pipe network: Connect both sides of the floating hose 10 with a diameter of 200 mm to the aquatic green plant cultivation component 20 through hemp ropes and place them on the lake surface, keeping a swing margin of 0.2 - 0.5 m, and then anchor the floating hose 10; Connect the anchor rod to the floating hose 10 through a hemp rope, or fix the anchor rod on the wall, or fix the anchor rod on the floating island to ensure that the floating hose 10 will not have a large displacement on the lake surface. The connection relationship of the floating hose 10 can also ensure that the aquatic green plant cultivation component 20 will not have a large displacement on the lake surface.

[0041] Step s03: Micro - pore aeration control: Introduce gas into the floating hose 10 and implement pulse aeration through the aeration pipe 101. The aeration intensity is 0.3 m 3 / (m·h), and the working cycle is aeration for 15 min / pause for 45 min; Utilize the 2 - 3 mm micro - bubbles generated by aeration to form an oxidation layer on the root surface;

[0042] Step s04: Real - time monitor the root growth rate through the fiber optic sensor. When the daily growth amount > 8 cm, trigger the cutting program, and the linkage mechanism 30 drives the root cutting module 40 to complete the cutting of the excess roots.
