Description

Technical Field

[0001] The invention relates to an ecological floating island which can be used for controlling farmland non-point source pollution and belongs to the technical field of water conservancy engineering. Background Art

[0002] Ecological floating islands are artificial islands, and the plants planted on them can degrade COD, nitrogen and other substances. They have comprehensive functions such as purifying water quality, improving landscapes, and eliminating waves. They have been widely used in water environment management of relatively large water bodies such as ponds and plain river networks. At present, ecological floating islands are mainly frame-type wet floating islands. The main body of the floating island is fixed underwater by weight, anchor or pile foundation, and is suitable for large waters. In response to farmland non-point source pollution, since the scale of farmland channels is generally small, the direct application of existing ecological floating islands to agricultural channels will significantly reduce the water-passing capacity of the channels and have an adverse effect on farmland drainage. Summary of the invention

[0003] The purpose of the present invention is to provide an ecological floating island used on a channel, which has little effect on the water flow capacity of the channel.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: the ecological floating island used in the channel of the present invention includes: a first drainage hole is provided at the warning water level of the first side wall of the channel, a first pulley is installed on the first side wall, a first water storage box is provided on the outer side of the first side wall, a second drainage hole is provided at the warning water level of the second side wall of the channel, a second pulley is installed on the second side wall, a second water storage box is provided on the outer side of the second side wall, a floating basket is provided in the channel, the first water storage box and the second water storage box have water outlet holes, the first water storage box is connected to one end of a first rope bypassing the first pulley, the other end of the first rope is connected to one end of the floating basket, the second water storage box is connected to one end of a second rope bypassing the second pulley, the other end of the second rope is connected to the other end of the floating basket; after the water in the channel rises to the warning water level, it can flow into the first water storage box from the first drainage hole and into the second water storage box from the second drainage hole, so that the first water storage box and the second water storage box can pull the floating basket upward to above the first drainage hole and the second drainage hole.

[0005] Furthermore, the floating basket of the present invention is fixedly connected with a first baffle and a second baffle. After the floating basket rises above the first drainage hole and the second drainage hole, the first baffle can cover the first drainage hole, and the second baffle can cover the second drainage hole.

[0006] Furthermore, the present invention provides a first slide rail on the outer side of the first side wall, so that the first water storage box can reciprocate up and down along the first slide rail; and / or, provides a second slide rail on the outer side of the second side wall, so that the second water storage box can reciprocate up and down along the second slide rail.

[0007] Furthermore, the present invention is provided with a third slide rail on the inner side of the first side wall, and a fourth slide rail on the inner side of the second side wall, so that the floating basket can reciprocate up and down along the third slide rail and the fourth slide rail.

[0008] Furthermore, the present invention provides a limiting device on the inner side of the first side wall and / or the inner side of the second side wall, and the limiting device is located above the first drainage hole and the second drainage hole, so that after the floating basket rises above the first drainage hole and the second drainage hole, the floating basket remains in the channel.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: after the water in the channel rises to the warning water level, it can flow from the first drainage hole into the first water storage box and from the second drainage hole into the second water storage box, so that the first water storage box and the second water storage box can pull the floating basket upward to above the first drainage hole and the second drainage hole, thereby ensuring that the floating basket is higher than the warning water level under large flow conditions and has little effect on the water flow of the channel. After the floating basket rises above the first drainage hole and the second drainage hole, the roots of the plants in the floating basket can contact the water most of the time, ensuring the survival of the plants in the floating basket. The present invention uses the first drainage hole and the second drainage hole to guide the water in the channel to the first water storage box and the second water storage box outside the channel, and realizes the automatic lifting of the floating basket in the channel through the weight change carried by the first rope and the second rope, thereby ensuring the water flow capacity of the channel, being green and energy-free; and because the ecological floating island has comprehensive functions such as purifying water quality, improving landscape, and eliminating waves, the good ecological environment it creates can purify the environmental water quality and can better solve problems such as agricultural pollution. The present invention can ensure the water passing capacity of small-scale water areas such as channels, overcomes the defect that existing ecological floating islands cannot be used for small-scale water areas such as farmlands, and can solve the problem of difficulty in pollution control of small-scale water areas such as farmlands.

DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Figures 1 to 4 A preferred embodiment of the present invention for an ecological floating island on a channel is shown. Figures 1 to 4 As shown, a first drain hole 3 is provided at the warning water level of the first side wall 20 of the channel, a first water storage box 4 is provided on the outer side of the first side wall 20, a second drain hole 8 is provided at the warning water level of the second side wall 21 of the channel, and a second water storage box 9 is provided on the outer side of the second side wall 21. In the present invention, only one pulley can be installed on the first side wall 20 and the second side wall 21, or multiple pulleys can be installed on each. As a preferred embodiment of the present invention, Figure 2 As shown, the first pulley 1 and the first pulley 14 can be installed at the top of the first side wall 20, and the second pulley 6 and the second pulley 15 can be installed at the top of the second side wall 21. Each pulley can be fixed to the top of the side wall of the channel through a pulley connecting device 13. A floating basket 11 is provided in the channel. The floating basket 11 includes a plant planting area 12 and plants that have a degradation effect on COD, nitrogen and other substances. The plants are planted in the plant planting area 12 of the floating basket 11. Most of the plants are emergent plants, which ensures that the plants will not be unable to survive due to being submerged in water when the water level fluctuates up and down. The plant planting area 12 on the floating basket 11 can be a hole-like structure, such as a round hole, so that while the plants are fixed on the floating basket 11, the roots of the plants can also effectively contact the water in the channel to ensure the survival of the plants. As shown Figure 2 As shown, one end of the first water storage box 4 is connected to one end of the first rope 2 passing around the first pulley 1, and the other end of the first rope 2 is connected to one end of the floating basket 11; and the other end of the first water storage box 4 is also connected to one end of the rope passing around the first pulley 14, and the other end of the rope is connected to one end of the floating basket 11. One end of the second water storage box 9 is connected to one end of the second rope 7 passing around the second pulley 6, and the other end of the second rope 7 is connected to the other end of the floating basket 11; and the other end of the second water storage box 9 is connected to one end of the rope passing around the second pulley 15, and the other end of the rope is connected to the other end of the floating basket 11.

[0017] Since the total weight of the floating basket 11 and the plants is greater than the buoyancy of the water on the floating basket 11 and the plants, the floating basket 11 does not change with the change of the water level without external pulling. Therefore, when the water level in the channel is lower than the first drainage hole 3 and the second drainage hole 8, the floating basket 11, the first water storage box 4 and the second water storage box 9 are all located below the first drainage hole 3 and the second drainage hole 8. At this time, the roots of the plants in the floating basket 11 are in contact with the water in the channel, and the pollution in the channel can be fully biodegraded by the plants, thereby achieving the purpose of improving the water quality in the channel and reducing pollution.

[0018] The warning water level is a warning water level in a large flow state or a channel overflow state. When the water level in the channel reaches the warning water level, the water in the channel rises and flows into the first water storage box 4 through the first water leakage hole 3 and flows into the second water storage box 9 through the second water leakage hole 8. The first water storage box 4 and the second water storage box 9 are both provided with a plurality of water outlet holes (not shown in the figure) so that the water in the water storage box can be discharged in time. The water outlet holes are preferably arranged at the bottom of the first water storage box 4 and the second water storage box 9. When the water outflow speed of the first water storage box 4 and the second water storage box 9 is lower than the water inflow speed, the total weight of the first water storage box 4 and the second water storage box 9 increases, so that the floating basket 11 can rise under the pulling force of the first water storage box 4 and the second water storage box 9 and be located above the first drainage hole 3 and the second drainage hole 8. Therefore, under the condition of large flow, the floating basket 11 is higher than the warning water level, so that the bottom space of the channel is increased and the first drainage hole 3 and the second drainage hole 8 are not blocked by the floating basket 11, thereby ensuring that the water in the channel can be smoothly discharged from the first drainage hole 3 and the second drainage hole 8, so that the water passing capacity of the channel is not affected. The position, size and number of the water outlet holes of the first water storage box 4 and the second water storage box 9, the position, size and number of the first drainage hole 3 and the second drainage hole 8, and the lengths of the first rope and the second rope are designed so that after the water in the channel flows from the drainage holes into the first water storage box 4 and the second water storage box 9 to a certain extent, the first water storage box 4 and the second water storage box 9 can pull the floating basket 11 upward to above the first drainage hole 3 and the second drainage hole 8 and keep the floating basket still in the channel.

[0019] As a preferred solution of the present invention, a pair of first slide rails 17 are provided on the outer surface of the first side wall 20 of the channel, and the first water storage box 4 can reciprocate up and down along the first slide rails 17; a pair of second slide rails 18 are provided on the outer surface of the second side wall, and the second water storage box 9 can reciprocate up and down along the second slide rails 18. As a preferred solution of the present invention, Figure 2As shown, a pair of third slide rails 16 may be provided on the inner surface of the first side wall 20, and a pair of fourth slide rails 19 may be provided on the inner surface of the second side wall 21, and the floating basket 11 may reciprocate up and down along the third slide rails 16 and the fourth slide rails 19 in the channel. In the present invention, there may be only one or more first slide rails, second slide rails, third slide rails and fourth slide rails, respectively. The installation positions of each pulley and slide rail, and the connection positions of each water storage box, floating basket and rope are preferably such that each water storage box and floating basket can be lifted and lowered smoothly.

[0020] As a preferred embodiment of the present invention, in order to ensure that the floating basket 11 can always be in the channel after it rises above the first drainage hole 3 and the second drainage hole 8, the floating basket 11 can be fixedly connected to the first baffle plate 5 and the second baffle plate 10, or a floating basket limiting device can be provided on the inner side of the first side wall 20 and / or the inner side of the second side wall 21. In addition, the floating basket 11 can also be designed to be always in the channel after it rises above the first drainage hole 3 and the second drainage hole 8 by considering factors such as the height of the channel, the position of the drainage hole, the length of the first rope and the second rope, and the relationship between the water outlet speed and the water inlet speed of the first water storage box 4 and the second water storage box 9.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, if the floating basket 11 is fixedly connected with the first baffle 5 and the second baffle 10, when the floating basket 11 rises above the first drainage hole 3 and the second drainage hole 8, the first baffle 5 can cover the first drainage hole 3, and the second baffle 10 can cover the second drainage hole 8. At this time, the first drainage hole 3 and the second drainage hole 8 no longer leak. Since the floating basket 11 rises above the first drainage hole 3 and the second drainage hole 8 at this time, the space at the bottom of the channel is increased, ensuring that the water flow capacity of the channel can be greatly enhanced at a large flow rate; and at this time, the floating basket 11 no longer rises, so that the floating basket 11 is placed in the channel and is in a stable state. When the first drainage hole 3 and the second drainage hole 8 no longer leak, the water in the first water storage box 4 and the second water storage box 9 still flows out through the water outlet. When the amount of water in the first water storage box 4 and the second water storage box 9 is reduced to a certain amount, the floating basket 11 descends together with the first baffle 5 and the second baffle 10, and drives the first water storage box 4 and the second water storage box 9 to rise. After the first baffle 5 and the second baffle 10 leave the corresponding drainage holes, if the water level in the channel is still high and is discharged from the first drainage hole 3 and the second drainage hole 8, the water in the channel will flow into the first water storage box 4 and the second water storage box 9 along the first drainage hole 3 and the second drainage hole 8 respectively, so that the first water storage box 4 and the second water storage box 9 will drop again, and drive the floating basket 11 and the first baffle 5 and the second baffle 10 to rise again. Therefore, through the reciprocating lifting of the floating basket 11, it can be ensured that the floating basket 11 in the floating island is higher than the warning water level under large flow conditions and has little effect on the water flow of the channel. At the same time, the plants in the floating basket play a role in purifying water quality and improving the landscape.

[0022] like Figure 2 As shown, if a limit device 22 of the floating basket is provided on the inner side of the first side wall 20 and / or the inner side of the second side wall 21, and the limit device 22 is located above the first drainage hole 3 and the second drainage hole 8, then when the floating basket 11 rises above the first drainage hole 3 and the second drainage hole 8, the limit device 22 can prevent the floating basket 11 from continuing to rise, so that the floating basket 11 is always placed in the channel and the roots of the plants on the floating basket 11 are still in contact with the water. As a preferred embodiment of the present invention, the limit device 22 can be installed at any one or more of the first slide rail, the second slide rail, the third slide rail, and the fourth slide rail.

[0023] The ecological floating island used in the channel of the present invention has the following advantages: the device relies on the gravity of water as the power for the operation of the entire device, so that the floating basket, water storage box, baffle, etc. can be automatically raised and lowered, and the water passing capacity of small-scale water areas such as channels can be guaranteed, overcoming the defect that the existing ecological floating island cannot be used for small-scale water areas such as farmland, and can solve the problem of difficulty in pollution control of small-scale water areas such as farmland, and it does not affect the water passing through agricultural channels, and effectively improves the quality of agricultural water. In addition, the present invention does not consume manpower and electricity during the operation process, and is green and environmentally friendly.
