Referring to fig. 1, 2 and 9, fig. 9 is a schematic structural diagram of an installed ecological belt constructing apparatus, in which, in the three diagrams, a is a beach and a shadow is a filling position of the supplementary sand, B is a state of the supplementary sand just after the supplementary sand is completely filled, C is a state of the supplementary sand after the supplementary sand is flushed for a period of time, fig. 1 is a schematic diagram of the beach in the prior art, and fig. 2 is a schematic diagram of a flow in the process of filling the supplementary sand (the original state in fig. 2 is a schematic diagram of the beach when the supplementary sand is not filled, and state one is a schematic diagram of the beach after the supplementary sand just after the supplementary sand is completely filled, and state two is a schematic diagram of the beach after the supplementary sand is flushed for a period of time).
In some embodiments, the embedded part 4 includes a fixed cross beam 5, one side surface of the fixed cross beam 5 is provided with a plurality of embedded rods 6 which can be embedded in supplementary sand, the other side surface of the fixed cross beam 5 is provided with a plurality of shaping rods 7, and the shaping rods 7 are connected with the partition net cover 1 through connecting pieces (the connecting pieces can be selected to support rods or chains or steel structure square tubes, etc., and can be set according to requirements during specific connection);
the floating part 3 comprises a floating column 8, a filtering and separating net block 9 and an outer blocking net 10, wherein the filtering and separating net block 9 is arranged between every two adjacent shaping rods 7, the floating column 8 floats on the water surface and is connected with the shaping rods 7 through ropes (the floating column 8 can move and does not pull the filtering and separating net block 9), the outer blocking net 10 is arranged on one side of the filtering and separating net block 9 away from the separation net cover 1, the side edge of the floating column 8 is fixedly connected with the end part of the outer blocking net 10, a plurality of blocking net blocks 11 are arranged on one side of the filtering and separating net block 9 close to the separation net cover 1, each blocking net block 11 is respectively arranged corresponding to each spacing zone, one end of each blocking net block 11 is fixedly connected with the side wall of the floating column 8, and the other end of each blocking net block 11 is fixedly connected with the corresponding end part of the separation net cover 1;

In order to achieve the purpose of blocking in the tide rise and fall, specifically, the buried rod 6 is buried in the supplementary sand first, so that the position of the fixed cross beam 5 is fixed, and when the floating column 8 floats on the water surface, the floating column 8 pulls the outer barrier 10 and the barrier block 11 to be in the states shown in fig. 3, 4 and 5 under the driving of the water flow.
During tide rising, external water flow can impact on the outer barrier 10 with pollutants, and as the outer barrier 10, the filter screen blocks 9 and the blocking back net blocks 11 are all of net structures (made of metal wires or plastic and other products can be selected), the outer barrier 10, the filter screen blocks 9 and the blocking back net blocks 11 can play the purpose of three-stage filtration (namely, the effect of three-stage filter screen structures), namely, the pollutants with the largest particles can be blocked outside by the outer barrier 10, the smaller pollutants can impact on the filter screen blocks 9 so as to realize secondary filtration, and after secondary filtration of the filter screen blocks 9, the blocking back net blocks 11 realize tertiary filtration, so that the mud of the pollutants to the beach can be reduced with larger probability under the condition of the filtration.
At the time of tide, the inner water flow can take away the sand and stone, at the moment, the sand and stone can impact on the blocking net block 11, and then the sand and stone are blocked by the blocking net block 11 so as to keep a spacing area.
It should be noted that the mesh diameter of the outer barrier 10 is slightly larger than the mesh diameter of the screen block 9, and the mesh diameter of the blocking net block 11 is slightly smaller than the mesh diameter of the screen block 9, so as to ensure that external contaminants (in the specific embodiment, the external contaminants are the contaminants which are impacted on the outer barrier 10 by the water flow during the flood tide) are filtered three times during the impact of the floating part 3, and sand and stones in the inner world (in the specific embodiment, the sand and stones which are driven by the water flow during the flood tide) are blocked by the blocking net block 11 to remain in the space, and as the blocking amount of the blocking net block 11 is increased, the sand and stones at the blocking net block 11 can be pumped to the beach by a suction pump or the like.
It should be noted that, because the area of the protection area required by the beach is large, the whole ecological band constructing apparatus is not provided singly but is formed by a plurality of ecological band constructing apparatuses, and the structure of the ecological band constructing apparatus can be referred to fig. 3.
In some embodiments, a space is formed between the outer barrier 10 and the filter screen block 9, a plurality of pulling belts 13 are arranged in the space, the pulling belts 13 can limit the position of the outer barrier 10, an opening is arranged at one end of the space away from the floating column 8, and sundries filtered by the filter screen block 9 can be led out through the opening by the space.
In order to prevent a significant accumulation of contaminants between the outer screen 10 and the screen block 9.
In some embodiments, a export block 14 is arranged between each screen block 9 and each return block 11;
one side surface of the guiding-out net block 14 is fixedly connected with one end of the filtering and separating net block 9 far away from the fixed cross beam 5, the other side surface of the guiding-out net block 14 is fixedly connected with one side surface of the blocking-back net block 11 far away from the separation net cover 1, and one side surface of the guiding-out net block 14 far away from the floating column 8 is provided with a shaping strip 15.
In order that contaminants do not accumulate in large amounts between the screen block 9 and the catch block 11.
In some embodiments, the setting position of the other side of the export net block 14 is not lower than the connection position of the export net block 14 and the filter screen block 9 based on the height direction of the filter screen block 9.
In order to make it easier for contaminants that accumulate between the screen block 9 and the catch screen block 11 to be conducted away.
Specifically, after the water flows through the outer barrier 10 with the contaminants, the contaminants remain in the space, the space is not easily bonded along with the limitation of the pulling belt 13, and the contaminants entering the space are directly discharged from the opening along the space, especially, after a period of flushing, the second state of fig. 2 can be referred to as schematic diagram and fig. 9, at this time, part of the supplementary sand flows to the C position, the opening is exposed, and the contaminants can be easily discharged.
At the same time, the part of the pollutant entering the interval can impact the blocking net block 11, and because the height of the filtering net block 9 is lower than that of the outer blocking net 10, part of the pollutant can pass through the filtering net block 9 and then impact the blocking net block 11 (the bottom of the blocking net block 11 is connected with the partition net cover 1, so that the bottom of the blocking net block 11 is not in a closed state, refer to fig. 4 and 5, that is, the pollutant can be discharged, and the pollutant can not always remain between the blocking net block 11 and the filtering net block 9, and because the part of pollutant is mostly trapped by the filtering net block 9, the situation that excessive quantity occurs does not need to be worry), part of pollutant can directly impact the blocking net block 11 (the part of pollutant can directly impact the blocking net block 11 because the filtering net block 9 does not trap), and can be accumulated and fall to the guiding net block 14 along with the blocking net block 11.
During tide, the water flow will impact the blocking net block 11 with sand and stones, at this time, the floating columns 8 will be driven to fall with the water flow, so that the floating columns 8 will move to the left with the blocking net block 11 (refer to fig. 3), and the blocking net block 11 will deflect with the guiding net block 14 with the connection position with the filtering net block 9 as the deflection center, and the sundries accumulated on the guiding net block 14 will be dumped to the interval.
In some embodiments, in order that the sand and stones in the tide are not taken away in a large amount, the firmness under the sand and stones needs to be ensured, and therefore, a plurality of inclined net blocks 16 are arranged in the partition net cover 1, and the inclined net blocks 16 can limit the flow speed of the supplementary sand towards the water bottom.
In some embodiments, with the gradual flushing of the supplementary sand or the slope of the beach being larger, the flow rate of the water during the falling tide or the rising tide being larger, in order to avoid the occurrence of water flow carrying pollutants or sand and stones passing from the floating columns 8, embodiments are provided comprising a plurality of floating rods 17 and a shielding net block 18, wherein when not deployed, all the floating rods 17 are movably connected with the floating columns 8 (referring to fig. 6, a clamping strip is arranged on the floating columns 8), and when deployed, all the floating rods 17 are connected with the shielding net block 18 and form a blocking structure, and the blocking structure is connected with the floating rods 17 and the partition net cover 1 through ropes;

two falling holes 20 are formed in the surface of the shielding net block 18, the two falling holes 20 are respectively positioned on the two side surfaces of the V-shaped blocking structure, an elastic net 21 is fixedly connected to the position, corresponding to the falling holes 20, of the outer surface of the V-shaped blocking structure, and one side, close to the separation net cover 1, of the elastic net 21 is not sealed.
In some embodiments, the area of the elastic web 21 is greater than or equal to the area of the drop hole 20.
Specifically, if the probability of the pollutant or sand passing through the floating column 8 needs to be reduced, the floating rod 17 can be unfolded according to fig. 7, when the tide is fluctuated or the tide falls, the water flow can impact the two buffer surfaces on the blocking structure, so that the water flow can not drive a large amount of sand and stone to move, meanwhile, once the pollutant is carried by the water flow through the floating column 8, the water flow can be wrapped and clamped in the blocking structure, namely, the V-shaped shielding net block 18 is reserved, if the pollutant with a heavier volume enters the V-shaped shielding net block 18, the pollutant can easily fall to the left end of the spacing area through the elastic net 21, the sand and stone cannot be greatly influenced, and once the tide falls, the water flow also can enter the V-shaped shielding net block 18 with the sand and stone.
The invention works when in work:
the additional sand is filled firstly, in the filling process, the separation net cover 1 and the blocking net cover 2 are buried, so that the water flow scouring resistance strength of the additional sand is high, at the moment, the floating part 3 floats on the water surface, when the tide rises, the external water flow can impact on the outer net block 10 with pollutants, and as the outer net block 10, the filtering net block 9 and the blocking net block 11 are all of a net structure (made of metal wires or plastic and other products can be selected), the outer net block 10, the filtering net block 9 and the blocking net block 11 can play the purpose of three-stage filtering (namely, the effect of three-stage filtering structure), namely, the pollutants with the largest particles can be blocked outside by the outer net block 10, the smaller pollutants can impact on the filtering net block 9 to realize secondary filtering, and after the filtering net block 9 is subjected to secondary filtering, the blocking net block 11 realizes tertiary filtering, and the probability of the pollution can be greatly reduced under the condition of the filtering.
At the time of tide, the inner water flow can take away the sand and stone, at the moment, the sand and stone can impact on the blocking net block 11, and then the sand and stone are blocked by the blocking net block 11 so as to keep a spacing area.
After the water flows through the outer barrier 10 with the contaminants, the contaminants remain in the space, the space is not easily bonded with the limitation of the pulling belt 13, and the contaminants entering the space are directly discharged from the opening along the space, especially, after a period of flushing, the second state of fig. 2 can be referred to as schematic diagram and fig. 9, at this time, part of the supplementary sand flows to the C position, the opening is exposed, and the contaminants can be easily discharged. (the arc arrow in the second state shown in fig. 2 indicates the direction of sand flow, and P in fig. 9 indicates the state of the entire ecological band constructing apparatus after being installed).
At the same time, the part of the pollutant entering the interval can impact the blocking net block 11, and because the height of the filtering net block 9 is lower than that of the outer blocking net 10, part of the pollutant can pass through the filtering net block 9 and then impact the blocking net block 11 (the bottom of the blocking net block 11 is connected with the partition net cover 1, so that the bottom of the blocking net block 11 is not in a closed state, refer to fig. 4 and 5, that is, the pollutant can be discharged, and the pollutant can not always remain between the blocking net block 11 and the filtering net block 9, and because the part of pollutant is mostly trapped by the filtering net block 9, the situation that excessive quantity occurs does not need to be worry), part of pollutant can directly impact the blocking net block 11 (the part of pollutant can directly impact the blocking net block 11 because the filtering net block 9 does not trap), and can be accumulated and fall to the guiding net block 14 along with the blocking net block 11.
During tide, the water flow will impact the blocking net block 11 with sand and stones, at this time, the floating columns 8 will be driven to fall with the water flow, so that the floating columns 8 will move to the left with the blocking net block 11 (refer to fig. 3), and the blocking net block 11 will deflect with the guiding net block 14 with the connection position with the filtering net block 9 as the deflection center, and the impurities accumulated on the guiding net block 14 will be dumped to the interval for discharging.
