Description

Technical Field

[0001] The present invention relates to the field of water body restoration, and in particular to a rural water body ecological restoration system. Background Art

[0002] As people's awareness of environmental protection gradually increases, the demand for water ecological restoration is also gradually increasing; at present, it is not only limited to the water quality control of the city's landscape water bodies, but also puts forward higher and higher requirements for the water quality in rural areas. For rural areas with high rainfall and relatively developed water systems, their water bodies are mainly composed of the main stream of the river, a large number of ditches that naturally flow into the main stream, and a large number of ditches that divert water from the main stream for irrigation. Therefore, to manage the water quality of natural water bodies in rural areas, it is necessary to consider the existence of a large number of small ditches. In particular, for a large number of natural ditches that flow into the main stream, the quality of the water they flow into directly affects the water quality of the main stream. Most of the existing on-site water treatment devices are large in size and complex in structure, which are difficult to apply to sewage treatment in small ditches, restricting the effect of water quality management on the main stream of rural rivers. Summary of the invention

[0003] The present invention provides a rural water ecological restoration system to solve the problem that the on-site water treatment devices in the prior art are difficult to apply to the water quality management of small ditches, thereby affecting the ecology of the main stream water body, so as to achieve the purpose of targeted treatment of the water quality of small ditches and improve the water quality of the water body.

[0004] The present invention is achieved through the following technical solutions:

[0005] A rural water ecological restoration system includes a floating tube, a planting trough is provided on the top surface of the floating tube, a first partition is arranged at the bottom of the planting trough, and the top height of the first partition is lower than the top height of the floating tube; it also includes a scum trough provided on the side of the floating tube, and the scum trough and the planting trough are separated by a second partition; it also includes a U-shaped channel located in the floating tube, one end of the U-shaped channel is connected to the bottom of the scum trough, and the other end of the U-shaped channel is connected to the bottom of the planting trough and is located between the first partition and the second partition; a first filter is arranged on the top surface of one end of the U-shaped channel connected to the bottom of the scum trough, and a second filter is arranged on the side of the U-shaped channel and located on the surface of the floating tube, and the second filter is located below the scum trough.

[0006] In view of the problem that the on-site water treatment devices in the prior art are difficult to apply to the water quality management of small ditches, the present invention proposes a rural water ecological restoration system, in which the floating cylinder, as the name implies, is a cylindrical structure that can float on the water surface, and the planting trough opened on the top is used to plant emergent plants to achieve the function of swamp filtering. The present application sets a first partition in the planting trough, and divides the planting trough into two parts through the first partition, one part of which is connected to the scum trough through a U-shaped channel. The bottom surface of the scum trough is the first filter screen, and the side of the U-shaped channel is the second filter screen. Water can enter the U-shaped channel from the first filter screen and the second filter screen, and then enter the planting trough through the U-shaped channel.

[0007] When the present application is in use, the float is set at the intersection where the ditch merges into the main stream, so that the scum tank is facing the incoming flow direction of the ditch, and the buoyancy of the float is used to make the liquid level above the first filter screen and below the top surface of the float, that is, the fluctuation of the liquid level is within the height range of the scum tank. For the debris that merges into the main stream with the ditch water flow and floats on the ditch surface and cannot sink to the bottom, it can be gathered in the scum tank of the present application, reducing the risk of such debris entering the main stream, and it is only necessary to regularly clean the debris gathered in the scum tank. The water flow entering the scum tank flows downward from the first filter screen into the U-shaped channel; and the water from the deeper ditch directly enters the U-shaped channel through the second filter screen. The water entering the U-shaped channel turns inside the U-shaped channel and then enters the planting trough. The large particles of debris carried therein can be precipitated through the turning structure of the U-shaped channel. The water entering the planting trough needs to pass over the first partition. The present application plants emergent plants in the planting trough on the side of the first partition away from the direction where the second partition is located. This layout method can add some planting media that are conducive to the establishment of the root system in the planting area of ​​the emergent plants, and prevent the planting medium from overflowing from the U-shaped channel through the first partition. At the same time, the large particles of debris that are washed into the planting area by the water flow can be settled in the planting area, thereby improving the collection and processing capabilities of the present application for non-surface particles of debris carried by the water flow.

[0008] The present application has a simple structure and can be miniaturized. It can process surface and deep water flows from the ditch at the same time. It has good filtering capabilities for both debris floating on the ditch surface and debris suspended in the middle, and can effectively avoid the inhalation of bottom sediment. Therefore, it has a long service life and maintenance cycle. It is particularly suitable for arrangement on main streams with relatively developed water systems and many small ditches converging therein, and has a significant effect on improving the water quality of main streams of rural rivers.

[0009] Furthermore, the bottoms of the planting trough and the scum trough are at the same height, the second partition extends downward to below the bottoms of the planting trough and the scum trough, and the two ends of the U-shaped channel are separated by the second partition.

[0010] In this solution, the second partition is not only used to separate the slag trough and the planting trough, but also extends downward into the system. The area facing the second filter is divided into a U-shaped structure through the second partition, thereby forming the U-shaped channel required by this application, avoiding the cumbersome processing operations required to open a separate U-shaped channel.

[0011] Furthermore, it also includes a water purification chamber located in the floating tube, a plurality of drainage holes are opened on the wall of the planting trough, and the drainage holes are connected to the water purification chamber through a drainage channel; a plurality of water outlet holes connected to the water purification chamber are opened on the side wall of the floating tube.

[0012] In this solution, the water entering the planting trough enters the drainage channel from the drainage hole, enters the water purification chamber through the drainage channel, and finally is discharged from each water outlet. This solution can prevent the water from overflowing directly from the top of the planting trough, and provide a stronger processing capacity for the water entering the floating tube through the water purification chamber.

[0013] Furthermore, the water purification chamber is filled with expanded clay, and the particle structure of expanded clay can achieve a good filtering effect. At the same time, expanded clay has the advantage of being light in weight, which is conducive to the float tube maintaining a normal floating state; the drainage hole is located at a high position on the wall of the planting trough, so as to minimize the risk of debris deposited in the planting trough or the loaded planting medium entering the drainage hole; a plurality of water outlet holes are evenly distributed in a ring shape on the side wall of the float tube.

[0014] Furthermore, an annular groove is provided at the bottom of the float cylinder, and the float cylinder also includes two arc-shaped baffles slidably fitted in the annular groove; the arc-shaped baffles are used to shield the water outlet, and the central angle of the arc-shaped baffles is 80°~120°.

[0015] Since the floating tube of the present application is placed at the intersection where the ditch enters the main river channel, there are various possible angles between the ditch and the main stream, and the flow direction of the main stream also has many ways. Therefore, if all the water outlets are always kept in an open state, some of the water outlets may easily face the ditch and cause reverse drainage. When the present solution is in use, the positions of the two arc-shaped baffles are adjusted so that one of the arc-shaped baffles is located in the direction of the ditch flow to avoid drainage in the direction of the water outlet in the direction of the ditch, and the other arc-shaped baffle is located on the opposite side of the previous arc-shaped baffle, so that the water outlet along the direction of the main stream water flow can be connected to the outside, while the water outlets in other directions are blocked as much as possible; this arrangement can not only reduce the risk of reverse drainage, but also utilize the kinetic energy of the main stream water flow to allow the main stream water flow to enter the clean water chamber through the water outlet at the upstream end, and guide the water in the clean water chamber to be quickly discharged from the water outlet at the downstream end; the main stream water flow can also be used to flush the inside of the clean water chamber, so as to facilitate the entrainment of debris deposited in the clean water chamber, which is more conducive to extending the working life of the present application and extending the maintenance cycle.

[0016] Furthermore, the outer wall of the floating cylinder is provided with longitudinal slide grooves located on both sides of the scum groove, and a slider is slidably connected in the longitudinal slide groove, and a steel cable is connected to the slider, and the end of the steel cable away from the slider is connected to an anchor.

[0017] Since the float of the present application needs to be placed at the intersection of the ditch and the main river channel when in use, in order to prevent it from being washed away by the water flow, two anchors are specially provided, and the two anchors are respectively located on both sides of the scum trough. The anchors are connected to the float through steel cables. When in use, the two anchors are anchored to confine the float to the designated area.

[0018] In addition, considering the different depths of water bodies and the constant changes in the liquid level of natural water bodies, the float is also in a state of constant fluctuation on the water surface, which makes the steel cable very easy to be broken or cause the anchor to fail; in order to overcome this problem, the present solution fixes the steel cable on the slider, and the slider can slide freely in the corresponding longitudinal slide groove, thereby ensuring the adaptive ability to the fluctuation of the float, and significantly improving the in-place stability of the present application.

[0019] In addition, the anchoring member in the present solution can be temporarily anchored by any known anchoring method, such as anchor rods, anchor cables, etc.

[0020] Furthermore, the outer wall of the floating cylinder is also provided with baffles located on both sides of the scum groove, and the baffles are located between the two longitudinal chutes. This solution guides more ditch flows into the scum groove and / or the U-shaped channel through two baffles, which is conducive to reducing the amount of water bypassing the floating cylinder and further improving the treatment effect of rural water bodies.

[0021] Furthermore, the baffle is fixedly connected to the first rotating shaft, a bearing seat is arranged on the outer side wall of the floating tube, and the first rotating shaft is rotatably matched with the bearing seat via a bearing; and a locking mechanism for limiting the rotation of the first rotating shaft is also included.

[0022] This solution makes the opening angle of the two baffles adjustable, thereby adapting to ditches of different widths, which is conducive to improving the adaptability of the present application. After the baffle angle is adjusted to the right position, it can be locked by a locking mechanism. The locking mechanism can be any mechanism that can be implemented by a person skilled in the art and can lock the rotation of the first rotating shaft, and is not specifically limited here.

[0023] Furthermore, the anchoring member includes a shell, an assembly groove provided on the side of the shell, and a limiting plate hinged to the shell through a second rotating shaft, and the limiting plate matches the assembly groove; a first anchoring hole penetrating the assembly groove is provided on the shell, and a second anchoring hole corresponding to the first anchoring hole is provided on the limiting plate; the second rotating shaft is located at one end of the shell away from the steel cable; and also includes a receiving groove provided on the limiting plate, an elastic rope received in the receiving groove, and a hanging ring provided on the surface of the shell.

[0024] Considering that the floating tube of the present application is placed at the intersection of the ditch and the main river channel, it may be surrounded by muddy tidal flats, and it is difficult to fix it by traditional anchoring methods. Only by extending the length of the steel cable to a suitable area can it be conveniently anchored. For this reason, this solution provides a special anchor, in which the limit plate is rotatably matched with the shell, and the limit plate can be stored inside the shell or opened as needed.

[0025] When conventional anchoring is required for positioning, the limit plate is stored inside the shell. At this time, the second anchor hole and the first anchor hole are opposite to each other, and temporary anchoring can be achieved by passing through the first anchor hole and the second anchor hole and inserting into the ground through anchor rods or anchor nails.

[0026] When in a tidal flat area with a lot of silt, the limit plate can be opened to make the anchor piece a V-shaped structure as a whole, stuck in the surrounding tree trunks, stones or other places that can be stuck, and then the elastic rope is pulled out and the free end of the elastic rope is put on the hanging ring.

[0027] Furthermore, the outer wall of the float can be detachably connected to a plurality of buoyancy devices, and a plurality of buoyancy compartments are provided inside the float to ensure the buoyancy of the float; the number of buoyancy devices can be flexibly set according to needs.

[0028] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0029] 1. The present invention discloses a rural water ecological restoration system, which has a simple structure and can be miniaturized. It can process the surface and deep water flows of the ditch at the same time, has good filtering ability for both the debris floating on the ditch surface and the debris suspended in the middle, and can effectively avoid the suction of bottom sediment. Therefore, it has a long service life and maintenance cycle. It is particularly suitable for being arranged on the main stream with a relatively developed water system and a large number of small ditches converging, and has a significant improvement effect on the water quality of the main stream of rural rivers.

[0030] 2. The rural water ecological restoration system of the present invention can reduce the risk of reverse drainage, and can also utilize the kinetic energy of the main stream to allow the water of the main stream to enter the clean water chamber through the water outlet at the upstream end, and guide the water in the clean water chamber to be quickly discharged from the water outlet at the downstream end; it can also utilize the main stream water flow to flush the inside of the clean water chamber, making it easier to entrain the debris deposited in the clean water chamber, which is more conducive to extending the working life of the present application and extending the maintenance cycle.
