Description

Technical Field

[0001] The present invention relates to the field of river ecological protection, and in particular to a vegetation restoration device and a restoration method for river ecological protection. Background Art

[0002] River ecological protection consists of two parts: water body protection and embankment protection. Water body protection usually improves the water body by planting aquatic plants. Embankment protection includes the reinforcement of embankment soil and the protection of embankment vegetation. At the same time, due to the fluidity of river water, a lot of garbage in the river will be located near the embankment.

[0003] Chinese patent CN116354515B discloses a river ecological protection and restoration device, including a floating plate, an outer fixed sleeve of the floating plate is provided with an outer frame, a connecting plate is vertically slidably installed along the rear edge of the outer frame, a winding mechanism is provided near the bottom of the front surface of the connecting plate, one end of a pull rope is fixedly connected to the lower surface of the floating plate, the lower end of the pull rope is connected to the winding mechanism, a floating block is provided on the outer surface of the pull rope, and the winding mechanism winding the pull rope includes the following processes in sequence: the pull rope is in a loose state between the floating plate and the winding mechanism, and the winding mechanism winds it until the pull rope is tightened; the pull rope is driven by the winding mechanism to make the floating plate move down and dive below the water surface until the floating block is received in the winding mechanism; after the floating block is received in the winding mechanism, the winding mechanism is relaxed, the floating plate floats up, and the floating block drives the pull rope to float up and reset.

[0004] The above scheme releases aquatic plants into the river channel, and can automatically clean up the garbage located on the top of the aquatic plants. However, the garbage floating on the river channel is usually lower than the aquatic plants planted with floats, and in some navigation channels, the water body cannot be improved by releasing floats. This is because the released floats will hinder navigation, and the floats do not have enough space to receive the garbage floating in the river channel, and the garbage cleaning effect in the river channel is not good. At the same time, the driving mechanism in the above scheme is mostly exposed to the outside, and it is also necessary to use the action of water flow. The garbage mixed in the water flow can easily entangle the driving mechanism, thereby damaging the driving mechanism. If the existing device for cleaning garbage on the river bank needs to completely cover the garbage area, the device needs to extend to the center of the river channel, which occupies the width of the river channel and is not conducive to normal navigation of the river channel.

[0015] The present invention also relates to a vegetation restoration method for river channel ecological protection, which uses a vegetation restoration device for river channel ecological protection, and the specific steps are as follows:

[0016] S1. Put the floating plate and the drainage shell arranged at the front end of the floating plate into the river bank at the same time, and evenly arrange the floating plate and the drainage shell along the extension direction of the river, so that the first opening of the drainage shell faces the flow direction of the water in the river, and the garbage in the river flows into the first drainage trough from the first opening.

[0019] 1. The drainage shell is arranged at the front end of the floating plate. The water flow in the river flows in a fixed direction under the influence of gravity.

Since multiple vegetation restoration equipment is arranged along the extension direction of the river channel, the garbage along the river will be intercepted once when passing through the vegetation restoration equipment, thus reducing the amount of garbage remaining in the river channel, and further reducing the impact of garbage on aquatic plants on the floating plate, ensuring the effect of river ecological protection, and at the same time, the width of the drainage shell does not need to completely cover the garbage area, thereby ensuring the channel width of the river.

[0020] 2. By setting up a floating box, a gravity ball and an extension rod, and opening a drainage hole at the bottom of the lifting box, the lifting box can automatically drain the water inside during the ascent process without consuming external energy or regular maintenance.

[0021] 3. By setting up an energy storage unit and a salvaging unit, the salvaging unit can immediately salvage the garbage in the connected area. At the same time, the energy storage unit uses the flowing water to store energy and supply power to the salvaging unit, thereby reducing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figure 1 , Figure 2 and Figure 4-Figure 7 A vegetation restoration device for river ecological protection comprises a fixed plate 1 vertically arranged at the side of the river bank and a floating plate 11 arranged at one side of the fixed plate 1; a drainage shell 3 is arranged on the side of the fixed plate 1 away from the river bank and is movable in the vertical direction, the drainage shell 3 is located at the front end of the floating plate 11, and a first opening is opened at the end of the drainage shell 3 in the length direction, and the water flow of the river flows into the drainage shell 3 from the first opening, and the drainage shell 3 rises and falls synchronously with the river water level, the lower half of the drainage shell 3 is submerged below the river water level, and the upper half of the drainage shell 3 is located above the river water level. An adsorption groove 31 is provided through the side wall of the shell 3 away from the fixed plate 1, and a mesh box 21 is provided inside the drainage shell 3. The mesh box 21 is located in the drainage shell 3 and on one side of the adsorption groove 31. The mesh box 21 divides the drainage shell 3 into a first drainage groove 32 and a second drainage groove 33. The water flowing into the drainage shell 3 from the first opening of the drainage shell 3 enters the first drainage groove 32, and the water flowing into the drainage shell 3 from the adsorption groove 31 enters the second drainage groove 33. A lifting box 22 is provided in the mesh box 21 to move back and forth in the vertical direction, and a second opening is provided on the upper part of the lifting box 22.

[0036] In river ecological protection, the water body of the river is often improved by planting aquatic plants. Although aquatic plants themselves can improve the water quality of the river, they are also easily affected by the external environment, such as garbage floating in the river. The traditional aquatic plant floating board 11 does not have the function of cleaning garbage. Although there is a device for cleaning the garbage on the floating board 11 in the prior art, it is impossible to collect the garbage in a unified manner. That is, the purpose of using aquatic plants is to improve the water environment of the river, thereby realizing the ecological protection of the river. However, with the flow of river water in the river, if the water body of the river is only managed by aquatic plants without processing the garbage, the water quality of the river cannot be guaranteed. At the same time, too much river garbage will surround the floating board 11. Even if the existing self-lifting cleaning method is used, it cannot be guaranteed that the garbage on the floating board 11 will be completely removed. When more garbage is accumulated on the floating board 11, the aquatic plants on the floating board 11 will be blocked, covered or squeezed by the garbage, which will cause the aquatic plants to die quickly, which will have a counter-effect on the ecological protection of the river.

[0037] In order to avoid the above situation, a drainage shell 3 is set at the front end of the floating plate 11 for receiving aquatic plants to drain the garbage. The specific working principle is as follows: when the lifting box 22 descends and sinks into the river water, the water in the second drainage groove 33 flows into the lifting box 22. When the lifting box 22 rises and is higher than the river water level, the water stored inside is discharged. The drainage shell 3 is set at the front end of the floating plate 11. The water flow in the river flows in a fixed direction under the influence of gravity. In this way, the flow direction of the water flow in the river usually does not change. The drainage shell 3 is set at the front end of the floating plate 11. end, and the first opening of the drainage shell 3 faces the oncoming side of the water flow in the river channel, ensuring that the flowing water can flow into the drainage shell 3 from the first opening. At the same time, since the floating plate 11 and the drainage shell 3 are both arranged on the bank of the river channel, the water flow in the river channel will flush most of the garbage in the river channel to the vicinity of the bank on both sides of the river channel when flowing. In this way, the drainage shell 3 arranged on the bank can collect most of the garbage, and since the drainage shell 3 is arranged at the front end of the floating plate 11, the river can no longer drive the garbage to the vicinity of the floating plate 11, thereby ensuring the growth safety of aquatic plants on the floating plate 11.

[0038] A drainage hole 27 is provided at the bottom of the lifting box 22. The lifting box 22 is placed in the net box 21 to prevent the garbage in the first drainage groove 32 and the second drainage groove 33 from accidentally flowing into the second opening and entering the lifting box 22 when the lifting box 22 is lifted. In this way, when the lifting box 22 is lifted, the garbage remaining in the lifting box 22 will block the drainage hole 27 in the lifting box 22, thereby causing the lifting box 22 to be unable to drain normally. Due to the limited width of the drainage shell 3, it is impossible for all the garbage located on the bank of the river to enter the first drainage groove 32 from the first opening, and some of the garbage will flow through one side of the drainage shell 3. In order to improve the garbage capture effect, an adsorption groove 31 is provided on the side of the drainage shell 3. By setting the net box 21 in the drainage shell 3 and setting a net box 21 inside the net box 21 The lifting box 22 that can float up and down in the vertical direction receives the water flow in the second drainage trough 33, that is, after the lifting box 22 is lowered, when the height of the second opening of the lifting box 22 is lower than the liquid level of the river, the water flow in the second drainage trough 33 flows into the lifting box 22 through the second opening, so that the water flow at the adsorption tank 31 flows into the second drainage trough 33, and the flowing water flow can suck the garbage flowing from one side of the drainage shell 3 into the second drainage trough 33, thereby completing the cleaning of the garbage. Since a plurality of drainage shells 3 and floating plates 11 are arranged along the extension direction of the river, the garbage along the river will be intercepted once when passing through the vegetation restoration equipment, thereby reducing the amount of garbage remaining in the river, thereby reducing the impact of garbage on the aquatic plants on the floating plate 11, and ensuring the effect of river ecological protection.

[0039] Reference Figure 6 and Figure 7: An extended baffle 23 is vertically fixed on the second opening of the lifting box 22. The extended baffle 23 is located on the side of the second opening close to the first drainage trough 32. The water flow in the first drainage trough 32 cannot pass through the net box 21 and flow into the lifting box 22 from the second opening. When the horizontal height of the second opening of the lifting box 22 is lower than the liquid level of the river, all the water flowing into the second opening flows into the second drainage trough 33 through the adsorption trough 31.

[0040] A linear drive 231 is vertically arranged on the upper part of the extension baffle 23, and the linear drive 231 is used to drive the extension baffle 23 to move in the vertical direction. By setting the extension baffle 23, when the lifting box 22 drops below the liquid level of the river water, the water flow in the first drainage trough 32 will not flow into the lifting box 22 from the second opening, so that all the river water flowing into the second opening comes from the second drainage trough 33. From the above description, it can be seen that there is a garbage area for the garbage floating on the bank of the river. The garbage area extends synchronously along the extension direction of the river, and the garbage area has a certain width, and the width of the drainage shell 3 cannot completely cover the garbage area. This is because if the drainage shell 3 is too wide, it will cause the river channel to narrow, affecting normal shipping. By setting the lifting box 22, the water flow in the second drainage trough 33 flows into the lifting box 2 2, so that the water flow located at the side of the drainage shell 3 will be sucked into the second drainage trough 33 through the adsorption groove 31, that is, the water in the second drainage trough 33 is received by the lifting box 22, and the flow direction of the water flowing through the side of the adsorption groove 31 is changed, and the floating garbage is driven by the water flow to flow into the second drainage trough 33, so as to complete the collection of garbage. In this way, the width of the drainage shell 3 does not need to be too wide, and the attraction generated by the second drainage trough 33 after the lifting box 22 is lowered will cover the garbage area on the river bank, and it does not need to be completely covered. This is because the vegetation restoration equipment is evenly arranged along the extension direction of the river. After interception and cleaning, the amount of garbage floating on the river can be greatly reduced.

[0041] Reference Figure 8 An extension rod 26 is vertically penetrated at the bottom of the lifting box 22, and the extension rod 26 slides with the lifting box 22 in the vertical direction. A floating box 24 is fixedly arranged at the lower part of the extension rod 26. The floating box 24 is a hollow structure and the hollow structure can be filled with air. A gravity ball 25 is fixedly arranged on the upper part of the extension rod 26. Drain holes 27 are opened around the position where the extension rod 26 penetrates the lifting box 22. When the bottom of the lifting box 22 contacts the river water level, the floating box 24 blocks the drainage hole 27. When the bottom height of the lifting box 22 is higher than the river water level, the floating box 24 gives way to the drainage hole 27. The maximum buoyancy generated by the floating box 24 after contacting the water is greater than the gravity of the gravity ball 25.

[0042] In this way, when the lifting box 22 descends, the bottom of the lifting box 22 gradually moves toward the liquid surface of the river water, and the floating box 24 at the bottom of the lifting box 22 moves synchronously with the lifting box 22 in the vertical direction. After the floating box 24 contacts the river water, the floating box 24 drives the extension rod 26 to slide, and the extension rod 26 drives the gravity ball 25 to rise. When the bottom of the lifting box 22 contacts the river water, the floating box 24 is completely submerged below the liquid surface of the river water. At this time, the buoyancy of the floating box 24 is the largest, and the floating box 24 blocks the drainage hole 27 at the bottom of the lifting box 22. As the lifting box 22 continues to descend, when the height of the second opening on the lifting box 22 is lower than the liquid surface of the river water, the water in the second drainage trough 33 flows into the lifting box 22 from the second opening. When the lifting box 22 descends to the lowest position, it begins to rise. When the bottom of the lifting box 22 leaves the water surface, the floating box 24 gradually emerges from the water surface, and as the lifting box 22 continues to rise, the floating box 24 gradually loses contact with the water surface, and the buoyancy of the river water on the floating box 24 gradually decreases. The gravity of the gravity ball 25 gradually becomes greater than the buoyancy of the floating box 24 as the lifting box 22 rises, so that the floating box 24 is withdrawn from the drainage hole 27, and the lifting box 22 can discharge the water inside it through the drainage hole 27. When the lifting box 22 descends again, the water in the lifting box 22 is completely drained, ensuring that the water in the second drainage trough 33 can be discharged into the lifting box 22 again after the lifting box 22 descends. It is worth noting that the water discharged from the drainage hole 27 passes through the net box 21 and flows into the first drainage trough 32 and the second drainage trough 33 respectively.

[0043] Reference Figure 2 and Figure 5 : A plurality of adsorption grooves 31 are provided, and the adsorption grooves 31 are evenly arranged on the side wall of the drainage shell 3 along the extension direction of the drainage shell 3. A guide plate 28 is provided on each adsorption groove 31, and the guide plate 28 is located in the second guide groove and extends along the water flow direction. The extension length of the guide plate 28 is greater than or equal to the extension length of the adsorption groove 31 in the same direction.

[0044] In order to improve the adsorption capacity of the adsorption groove 31, a plurality of adsorption grooves 31 are arranged on the side wall of the drainage shell 3, so as to improve the garbage capture effect. In order to prevent the garbage entering the second drainage groove 33 from being discharged again from the next adsorption groove 31, a guide plate 28 is arranged on the adsorption groove 31. After the previous adsorption groove 31 adsorbs the garbage, the guide plate 28 will suck the garbage in the second drainage groove 33 and separate it from the subsequent adsorption groove 31, so that the garbage cannot approach the subsequent adsorption groove 31 during the flow process, ensuring that the garbage entering the second drainage groove 33 from the adsorption groove 31 will not overflow in the opposite direction.

[0045] Reference Figure 1 , Figure 6 and Figure 7There is a connecting area between the end of the first drainage groove 32 and the end of the second drainage groove 33. Garbage gathers in the connecting area. A salvage unit 4 is arranged in the connecting area. The salvage unit 4 includes an inclined circulating belt 42. Salvage claws 41 are evenly arranged on the circulating belt 42. When the circulating belt 42 rotates, the salvage claws 41 are driven to rotate synchronously.

[0046] The salvage unit 4 also includes a rotary driver 43 and a driving wheel 44. Two driving wheels 44 are provided. The two driving wheels 44 are arranged along the inclined direction of the circulating belt 42. The circulating belt 42 is sleeved on the two driving wheels 44 and cooperates with the two driving wheels 44 in transmission. The rotary driver 43 is provided at one end of one of the driving wheels 44. The rotary driver 43 is used to drive the driving wheel 44. The rotary driver 43 is preferably a servo motor. After the rotary driver 43 is started, the rotary driver 43 can drive the circulating belt 42 to rotate through the driving wheel 44, so that the salvage claw 41 provided on the circulating belt 42 can smoothly salvage the garbage located in the connecting area.

[0047] Reference Figure 3 A receiving groove 45 is provided below the higher side of the circulating belt 42. The receiving groove 45 is provided horizontally, and the bottom of the receiving groove 45 is an inclined structure. The bottom of the receiving groove 45 is inclined downward toward the fixed plate 1. An extending claw 46 is fixedly provided on the side of the receiving groove 45. The extending claw 46 is arranged alternately with the rotating salvaging claw 41.

[0048] In this way, when the circulating belt 42 rotates, the salvaging claw 41 on the circulating belt 42 can pick up the garbage and put it into the receiving groove 45, and it can be discharged through the receiving groove 45. A collecting bucket is provided on the side of the fixed plate 1 close to the embankment. The receiving groove 45 discharges the received garbage into the collecting bucket, and the garbage in the collecting bucket can be cleaned away regularly by the staff. The extending claw 46 provided on the receiving groove 45 is to avoid the situation where part of the garbage remains on the salvaging claw 41, ensuring that the garbage on the salvaging claw 41 can completely fall into the receiving groove 45.

[0049] Reference Figure 1 , Fig. 9 and Fig.10 An energy storage unit 5 is arranged on one side of the drainage shell 3, and the energy storage unit 5 includes an energy storage blade 51. The axial direction of the energy storage blade 51 is parallel to the extension direction of the drainage shell 3, and the energy storage blade 51 can be driven to rotate when the water flows through the energy storage blade 51. A generator 52 is arranged on the upper part of the energy storage blade 51, and a transmission assembly 53 is arranged between the input end of the generator 52 and the energy storage blade 51. When the energy storage blade 51 rotates, the input end of the generator 52 is driven to rotate through the transmission assembly 53.

[0050] The transmission assembly 53 includes a synchronous wheel 531 and a synchronous belt 532. There are two synchronous wheels 531. The two synchronous wheels 531 are fixedly arranged at the input end of the generator 52 and the end of the energy storage blade 51 respectively. The synchronous belt 532 is sleeved on the two synchronous wheels 531 and cooperates with the two synchronous wheels 531 in transmission. When the energy storage blade 51 rotates under the action of the river, the synchronous belt 532 can be driven to rotate, thereby causing the generator 52 to start generating electricity. A battery for energy storage is arranged on one side of the generator 52. The electric energy stored in the battery is used to power the salvage unit 4, thereby reducing the energy consumption of the salvage unit 4 during operation.

[0051] Reference Fig. 9 and Fig.10 A cover shell 54 is provided on the outer periphery of the energy storage blade 51. The cover shell 54 is a rotating shell-like structure. The end of the cover shell 54 facing the water flow is a spherical structure. Water-permeable grooves are evenly opened on the cover shell 54. A blade 55 is provided on the side of the cover shell 54 facing the first opening. The blade 55 rotates synchronously with the energy storage blade 51, and the blade 55 contacts the inner wall of the cover shell 54.

[0052] Since there are objects in the river that are easily entangled, such as water plants, it is necessary to set a cover 54 on the outside of the energy storage blade 51, so that the cover 54 can protect the energy storage blade 51 and prevent the energy storage blade 51 from being entangled by water plants. At the same time, a blade 55 is set at the front end of the energy storage blade 51, so that the energy storage blade 51 drives the blade 55 to rotate when it rotates, so that part of the water plants attached to the cover 54 can be cut off, thereby ensuring the stable operation of the energy storage blade 51.

[0053] Reference Figure 4 and Figure 5 : The floating plate 11 can only rise and fall synchronously with the liquid level of the river water in the river channel in the vertical direction. The width of the floating plate 11 is less than or equal to the width of the drainage shell 3. A float 12 is fixedly arranged around the drainage shell 3. The float 12 provides buoyancy for the drainage shell 3, and the float 12 rises and falls synchronously with the floating plate 11.

[0054] By setting the width of the floating plate 11 to the width of the small rain drainage shell 3, it is possible to prevent some garbage from hanging on the floating plate 11 when the river drives the garbage to flow. Under the action of water flow for a long time, more and more garbage accumulates in a corner of the floating plate 11, which can easily damage the overall structure of the floating plate 11.

[0055] Reference Figure 1-Figure 10 The present invention also relates to a vegetation restoration method for river ecological protection, which uses a vegetation restoration device for river ecological protection, and the specific steps are as follows:

[0056] S1. Put the floating plate 11 and the drainage shell 3 arranged at the front end of the floating plate 11 into the river bank at the same time, and evenly arrange the floating plate 11 and the drainage shell 3 along the extension direction of the river, so that the first opening of the drainage shell 3 faces the flow direction of the water in the river, and the garbage in the river flows into the first drainage groove 32 from the first opening.

[0057] S2. The garbage that does not flow into the first drainage trough 32 from the first opening flows through one side of the drainage shell 3. The lifting box 22 in the drainage shell 3 is lifted and lowered reciprocatingly in the vertical direction. When the lifting box 22 drops to the lowest position, the horizontal height of the second opening on the lifting box 22 is lower than the liquid level of the river channel. The water in the second drainage trough 33 flows into the lifting box 22 through the second opening. The water flow at the adsorption trough 31 flows into the second drainage trough 33. The garbage passing through one side of the drainage shell 3 flows into the second drainage trough 33 from the adsorption trough 31.

[0058] Working principle: the drainage shell 3 is arranged at the front end of the floating plate 11, and the water flow in the river flows in a fixed direction under the influence of gravity, so that the flow direction of the water flow in the river usually does not change. The drainage shell 3 is arranged at the front end of the floating plate 11, and the first opening of the drainage shell 3 is facing the oncoming side of the water flow in the river, ensuring that the flowing water can flow into the drainage shell 3 from the first opening. At the same time, since the floating plate 11 and the drainage shell 3 are both arranged on the bank of the river, the water flow in the river will flush most of the garbage in the river to the vicinity of the bank on both sides of the river when flowing. In this way, the drainage shell 3 arranged on the bank can collect most of the garbage, and since the drainage shell 3 is arranged at the front end of the floating plate 11, the river can no longer drive the garbage to the vicinity of the floating plate 11, thereby ensuring the growth safety of aquatic plants on the floating plate 11.

[0059] Due to the limited width of the drainage shell 3, it is impossible for all the garbage located on the bank of the river to enter the first drainage trough 32 from the first opening. Some of the garbage will flow through one side of the drainage shell 3. In order to improve the garbage capture effect, an adsorption groove 31 is opened on the side of the drainage shell 3, and a net box 21 is arranged in the drainage shell 3 and a lifting box 22 that can float up and down in the vertical direction is arranged in the net box 21 to receive the water flow in the second drainage trough 33. That is, after the lifting box 22 is lowered, when the second opening height of the lifting box 22 is lower than the liquid level of the river, the second drainage trough 33 is opened. The water flow in the flow trough 33 flows into the lifting box 22 through the second opening, so that the water flow at the adsorption trough 31 flows into the second drainage trough 33, and the flowing water can suck the garbage flowing from one side of the drainage shell 3 into the second drainage trough 33, thereby completing the cleaning of the garbage. Since a plurality of vegetation restoration equipment are arranged along the extension direction of the river channel, the garbage along the river will be intercepted once when passing through the vegetation restoration equipment, thus reducing the amount of garbage remaining in the river channel, thereby reducing the impact of garbage on the aquatic plants on the floating plate 11, and ensuring the effect of river ecological protection.

[0060] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
