DETAILED DESCRIPTION

[0023] The above and other embodiments and advantages of the present application are described in detail by referring to the attached drawings, in which:

[0024] In one embodiment, as shown in Figures 1-7

[0025] ​The embodiment provides a plant cultivation device for water ecological restoration, which comprises a floating island 1, a cultivation frame 2 and an electric drive assembly, a notch 101 is formed in the middle of the floating island 1, the cultivation frame 2 is arranged in the notch 101, a holding cabin 3 in communication with the notch 101 is arranged at the bottom of the notch 101, a drainage port 301 is formed in the front of the holding cabin 3, and discharge ports 302 are formed at the two sides of the holding cabin 3; in addition to providing a cultivation condition for root systems, water flow entering the holding cabin 3 is discharged to the two sides through the discharge ports 302, so that the water body does not stay in the holding cabin 3 for a long time to avoid the occurrence of dead water, and the water body is ensured to be flowing. An adjusting plate 4 is connected to the notch 101, the adjusting plate 4 is driven to the cultivation frame 2 through a transmission structure, a stepped groove 102 is formed in the inner side of the notch 101 and located above the holding cabin 3, and the bottom surface of the cultivation frame 2 falls on the stepped groove 102; the electric drive assembly comprises a first water quality sensor 5 arranged in the holding cabin 3, a controller arranged on the floating island 1, an electric cylinder 6 and a water pump 7, the electric cylinder 6 is drivingly connected to the cultivation frame 2, and the water pump 7 and the electric cylinder 6 are controlled by the controller; when the adjusting plate 4 is rotated upwards to the bottom of the cultivation frame 2, the water pump 7 is used to supply water to the cultivation frame 2.

[0026] In use, the cultivation device is placed in a water environment with the floating island 1, and aquatic green plants are cultivated; the green plants are planted in the cultivation frame 2, the root systems enter the holding cabin 3 along the notch 101 and enter the water environment from the holding cabin 3, water flow enters the holding cabin 3 through the drainage port 301, and then flows to the peripheral water environment through the discharge ports 302 after a short stay in the holding cabin 3; the short stay of the water flow in the holding cabin 3 prolongs the contact opportunity with the first water quality sensor 5; if the water environment in which the cultivation device is located is polluted, the water flow will continuously flow to the holding cabin 3 and is collected by the holding cabin 3 and then fed back to the first water quality sensor 5; the water quality is detected by the first water quality sensor 5, and a water quality signal is fed back to the controller or a terminal device in a control room; at the same time, a control module in the controller sends an instruction to the electric cylinder 6, so that the electric cylinder 6 drives the cultivation frame 2 to ascend along the notch 101; since the aquatic green plants are cultivated on the cultivation frame 2 and the root systems grow in the holding cabin 3, when the cultivation frame 2 ascends due to water pollution through the above-mentioned driving mode, the green plants ascend with the cultivation frame 2, and the root systems of the green plants are separated from the polluted water environment, so that the aquatic green plants achieve the cultivation purposes of intelligent detection and intelligent protection.

[0027] As described above, Figure 7As shown, when the cultivation frame 2 is lifted, the transmission structure drives the adjusting plate 4 to rotate upwards, and the adjusting plate 4 is rotated to the bottom side of the slot 101, at this time the adjusting plate 4 is equivalent to form a "bottom sealing" at the bottom of the cultivation frame 2, the controller sends a command to the water pump 7, and the water pump 7 draws water from a remote water area through the water inlet pipe to the cultivation frame 2, although the root system is separated from the original water area (polluted water area), by this way of remote water seeking, the uncontaminated water source (because it is impossible that all water areas are contaminated) is drawn into the cultivation frame 2 for the root system to cultivate, because there is no sealing relationship between the adjusting plate 4 and the bottom side of the slot 101, when the new water source enters the cultivation frame 2, in addition to providing new water conditions for the root system, the water source will also be discharged downward through the gap between the adjusting plate 4 and the slot 101, avoiding the occurrence of dead water, and this water source will enter the holding cabin 3 and flow to the polluted water area, so as to neutralize the polluted water area quickly. After the first water quality sensor 5 detects that the water area pollutants disappear (after artificial treatment or neutralization wash away), the water quality signal is fed back to the controller or the terminal equipment in the control room, at the same time, the control module in the controller sends a command to the electric cylinder 6, so that the electric cylinder 6 drives the cultivation frame 2 to descend along the slot 101, so that the root system re-enters the original water area, and the controller controls the water pump 7 to stop remote water adjustment, so that the cultivation device returns to the normal cultivation state.

[0028] The clean water injected into the cultivation frame 2 flows back to the holding cabin 3 through the gap, and is discharged to the polluted water area, accelerating the dilution and diffusion of the pollutants and natural degradation; the transmission structure linkage lifting and overturning action reduces the independent driving components; the controller transmits data remotely and makes decisions, reducing the artificial inspection intensity and improving the large-scale water area repair efficiency.

[0029] As shown in Figure 2 , Figure 3 and Figure 7 , the adapter end of the adjusting plate 4 is provided with a rotating shaft 401, the transmission structure includes a gear 8 fixed on the rotating shaft 401, and further includes a gear rack 9 fixed on the cultivation frame 2, the gear rack 9 is vertically downward and engages with the gear 8. When the cultivation frame 2 is lifted, the gear rack 9 is lifted, the gear rack 9 engages with the gear 8 to rotate, the gear 8 drives the rotating shaft 401 to rotate, and the rotating shaft 401 drives the adjusting plate 4 to rotate to the bottom side of the slot 101, so as to act as a bottom "sealing" of the cultivation frame 2. This engagement relationship makes the rotating "opening degree" of the adjusting plate 4 more stable, for example, when the cultivation frame 2 is lowered again, the gear rack 9 engages with the gear 8 in the reverse direction, the gear 8 drives the rotating shaft 401 to rotate in the reverse direction, and the rotating shaft 401 drives the adjusting plate 4 to rotate in the reverse direction to away from the bottom end of the slot 101, so that the bottom "sealing" of the cultivation frame 2 disappears, at this time the cultivation frame 2 enters the holding cabin 3 again, and the water area introduced through the drainage port 301 provides cultivation conditions for the root system.

[0030] In order to make the lifting of the cultivation frame 2 more stable and realize two-way guidance, a gap 103 is left between the inner surface of the slot 101 and the cultivation frame 2, and a rolling body 201 is arranged on the outer wall surface of the cultivation frame 2, which extends into the gap 103 and rolls against the inner surface of the slot 101. The rolling body 201 can be a spherical contact wheel, for example, a universal ball wheel is installed on the outer wall of the cultivation frame 2, and the other end of the universal ball wheel rolls against the inner surface of the slot 101. When the electric cylinder 6 drives the cultivation frame 2 to lift, the cultivation frame 2 is lifted by rolling against the slot 101 through the universal ball wheel, so that the lifting is stable.

[0031] The water pump 7 is on the same side as the drainage port 301, and a discharge pipe 701 is connected to the water outlet of the water pump 7. A discharge seat 202 is installed in the cultivation frame 2, and the outer end of the discharge seat 202 extends out of the cultivation frame 2 into the gap 103. The discharge pipe 701 extends into the gap 103 and is connected to the outer end of the discharge seat 202. The water inlet of the water pump 7 is connected to a water inlet pipe, which is away from the floating island 1 and extends into the far water area. The water pump 7 and the water inlet pipe take water from the far water area of the floating island 1. When the first water quality sensor 5 detects a sudden change in the water quality of the water area, the electric cylinder 6 drives the cultivation frame 2 to rise along the slot 101, so that the root system is separated from the water area. At the same time, the water pump 7 takes water from the far water area through the water inlet pipe and directly discharges the water from the far water area into the discharge seat 202 through the discharge pipe 701, and then discharges the water from the discharge seat 202 into the cultivation frame 2, so that the root system of the aquatic green plant always maintains an aquatic state and does not affect its normal cultivation.

[0032] It needs to be further explained that, as shown in Figure 7 Although the adjusting plate 4 rotates upward to the bottom end of the slot 101, there is a large space between the bottom end of the cultivation frame 2 after lifting, and the water taken by the discharge pipe 701 is distributed into the cultivation frame 2 through the discharge seat 202 and falls on the adjusting plate 4. At this time, the adjusting plate 4 is rotated upward and attached to the bottom end of the slot 101, which is equivalent to the "bottom sealing" of the cultivation frame 2. After the water level rises rapidly, it will form an aquatic condition for the roots extending into the adjusting plate 4. Because whether the cultivation frame 2 rises or falls, the root system of the aquatic green plant always extends to the bottom side of the cultivation frame 2, that is, when the cultivation frame 2 falls into the holding cabin 3, the root system enters the holding cabin 3 to be cultivated by the water in the water area of the floating island 1. After the cultivation frame 2 rises, the root system is separated from the water area of the floating island 1, and at this time it can be cultivated by the water adjusted by the discharge pipe 701. The latter water not only discharges downward through the gap between the adjusting plate 4 and the slot 101, but also discharges downward through the intercommunication hole 403, so there is no dead water phenomenon, and the root system is ensured to be in an active water body for cultivation.

[0033] As shown in Figure 3As shown, the transition end of the adjusting plate 4 and the holding cabin 3 form a clamping cavity 402 relative to the outlet end of the drainage port 301, the first water quality sensor 5 is close to the transition end of the adjusting plate 4 and located in the clamping cavity 402, the transition end of the adjusting plate 4 is provided with an intercommunication port 403, the holding cabin 3 communicates with the clamping cavity 402 through the intercommunication port 403, and the first water quality sensor 5 is in the same straight line with the intercommunication port 403. When the adjusting plate 4 rotates downward (the cultivation frame 2 is lowered in the holding cabin 3, and the root system is inserted into the water area where the holding cabin 3 is located), the clamping cavity 402 is formed between the adjusting plate 4 and the holding cabin 3, and the adjusting plate 4 is limited to be vertically downward under the action of the rack 9 engaging with the gear 8, the water flow enters the holding cabin 3 from the drainage port 301, part of the water flow is released into the clamping cavity 402 through the intercommunication port 403, and the clamping cavity 402 is used for collecting and collecting the first water quality sensor 5, so that the sensing end of the first water quality sensor 5 can quickly detect the water quality.

[0034] The two ends of the discharge seat 202 in the length direction are close to the two sides of the inner cavity of the cultivation frame 2, a plurality of fine holes 203 are densely provided along the length direction of the discharge seat 202, and the plurality of fine holes 203 extend to the outer end of the discharge seat 202 and are communicated with the discharge pipe 701. The discharge pipe 701 injects the water flow from a long distance into the discharge seat 202, and the water flow is uniformly distributed to the cultivation frame 2 through the fine holes 203 on the discharge seat 202, so that local concentration of the water flow is avoided, and a cultivation dead angle is formed for the root system after rising.

[0035] The bottom end of the cultivation frame 2 is provided with a surrounding plate 204, and the electric driving assembly further comprises a second water quality sensor 205 mounted on the surrounding plate 204. The second water quality sensor 205 is on the same side of the transition end of the adjusting plate 4, and the second water quality sensor 205 is above the intercommunication port 403. The second water quality sensor 205 is used to detect the water quality of the water body from a long distance. If the water flow also has water quality problems, the second water quality sensor 205 will also feed back a signal to the controller, and the controller triggers the water pump 7 to stop long-distance water diversion. The water inlet pipe connected to the water pump 7 is thrown to other water areas by human, and the water pump 7 is started by human to continue water diversion, detection and use.

[0036] The electric cylinder 6 is vertically arranged in the gap 103, and the action rod of the electric cylinder 6 is vertically connected to the outer wall of the cultivation frame 2. The electric cylinder 6 is arranged in the gap 103 to form a storage, thereby saving space.

[0037] The water pump 7 of the present application is used to divert water from a long distance through the water inlet pipe, which is not limited to diverting water from the same water area or different water areas. The probability that the long-distance water diversion and the water area where the device is located are both polluted is extremely low. Therefore, through the present embodiment, the requirements can be met.
