[0002] The health of aquatic ecosystems is crucial to maintaining biodiversity. Restoration can promote the reproduction and growth of aquatic organisms. In addition, water pollution can affect human health and ecosystems. Restoration can improve water quality and ensure safe water use. In the process of water ecological restoration, the more effective way is to clean up the floating on the surface of the water and put the restoration agent into the water. The restoration agent is usually sprayed on the surface of the water. Although this method is fast and direct, it is difficult to effectively treat pollutants in the sediments at the bottom of the water because the spraying is mainly aimed at the water surface, resulting in low overall mixing and reaction efficiency. In addition, the restoration agent gathers on the surface and is easily washed away by wind and waves, further reducing its diffusion ability. Therefore, the diffusion of the spraying method is poor and the role of the restoration agent cannot be fully utilized. Summary of the invention

[0011] Preferably, the aeration assembly includes an aerator installed on the top of the liquid storage tank, and a ventilation pipe extending to above the center of the annular tube is connected to the output end of the aerator, and a plurality of branch air guide pipes connected to the tail end of the ventilation pipe are connected to the interior along the inner wall of the annular tube, and the branch air guide pipes are inclined from bottom to top from one end in contact with the annular tube to the other end.

[0012] Preferably, the branch air duct and the branch liquid duct extend in directions located at the inlet of the large-pore slot aeration head, and the aerator introduces low-pressure air into the branch air duct, which is collected in the large-pore slot aeration head to generate bubbles and discharged to achieve water flow disturbance.

[0018] 4. The present invention increases the impact force of the liquid repair agent discharged outward along the large-pore slot aeration head by introducing air into the inlet end of the large-pore slot aeration head, thereby increasing the contact area between the repair agent and the target substance.

[0034] Embodiment 1

[0035] To effectively solve the problem of slow diffusion of remediation agents released into water bodies, please refer to Figure 1-Figure 7This embodiment proposes an ecological restoration device for water bodies used for environmental management, which can use the placed restoration agent to help decompose pollutants in the water body and improve water quality while cleaning floating garbage on the water surface. The water body ecological restoration device has a lifting frame 1 and a double-layer trash can 2 mounted on the lifting frame 1. A water pump 3 is installed at the bottom of the lifting frame 1 to force the garbage floating on the water surface to enter the double-layer trash can 2 when the water in the double-layer trash can 2 is extracted. The output end of the water pump 3 is detachably connected to a flange with a derivation component 4 for making the extracted water spray upward in a multi-point distributed manner along the bottom of the double-layer trash can 2. A delivery mechanism 5 for supplying a liquid restoration agent to the water flow direction inside the derivation component 4 is installed on the lifting frame 1, and an aeration component 6 for supplying low-pressure air to the inside of the derivation component 4 is installed on the delivery mechanism 5. In actual application, the lifting frame 1 is placed along the shore into the water body to be repaired, and the double-layer trash can 2 is almost submerged in the water. The overall structure formed by the double-layer trash can 2 and the water pump 3 is basically consistent with the structure and function of the double-layer trash can in the prior art. When the water pump 3 is running, the water inside the double-layer trash can 2 is extracted, and then the water flows along the path in the pipe of the outlet component 4, and finally discharged in a multi-point dispersed manner, and the liquid repair agent is placed near the entrance end of the outlet component 4 in cooperation with the placing mechanism 5. As the water body is pumped into the outlet component 4, the water flow with greater impact force will collide with it, thereby ensuring that the repair agent is fully mixed with this part of the water body and improving the effect of the repair agent. In addition, through the power of the water pump 3, the repair agent can be quickly spread to the target position and cover a larger water body. At the same time, the low-pressure air injected into the internal pipeline of the outlet component 4 further enhances the water fluidity, so that the water body with the repair agent is discharged faster and more impactfully, thereby further expanding the diffusion effect of the repair agent in the vicinity of the device.

[0036] Embodiment 2

[0037] Under normal circumstances, the water pumped by the pump 3 in the double-layer trash can 2 will be directly discharged along the output end of the pump 3. Therefore, only the water at the single point of the discharge port will be disturbed, making the water circulation effect of the entire water body poor. In order to effectively improve the activity of the water circulation of the entire water body. Figure 1 and Figure 2As shown, the outlet assembly 4 includes a front section conduit 401 detachably connected to the output end of the water pump 3, an annular tube 402 is arranged below the double-layer trash can 2, the tail end of the front section conduit 401 is connected to a middle section conduit 403 extending to the bottom of the center of the annular tube 402, the tail end of the middle section conduit 403 is connected to a plurality of branch liquid guide tubes 404 connected to the interior along the inner wall of the annular tube 402, and the branch liquid guide tubes 404 are inclined from top to bottom from one end in contact with the annular tube 402 to the other end, and the outer side surface of the annular tube 402 is installed with large-pore slot aeration heads 405 with the same number as the branch liquid guide tubes 404. In actual applications, the water inside the double-layer trash can 2 is extracted by the water pump 3 and sent to the front section conduit 401 inside the outlet component 4, and then flows along the middle section conduit 403 and dispersed to several branch liquid guide tubes 404. After that, when entering the annular tube 402, it will be discharged outward along the large-hole slot aeration head 405 along the direction of water flow impact. Since several large-hole slot aeration heads 405 are arranged in a circular shape and equidistantly on the side of the annular tube 402, the water extracted by the water pump 3 is dispersed to several points for spraying, reducing the slow-flowing or non-flowing areas in the water body, ensuring that the water circulation of the entire water body is more active.

[0038] Embodiment 3

[0039] The front section conduit 401 is composed of a straight tube 4011, a rectangular tube 4012 connected to the straight tube 4011, and a shrink tube 4013 integrally connected to the rectangular tube 4012. The two ends of the shrink tube 4013 are arranged in a square and a circle respectively, and the middle part of the bottom wall of the shrink tube 4013 is at the same height as the bottom wall of the rectangular tube 4012. The rectangular tube 4012 is connected to the tail end of the delivery mechanism 5.

[0040] like Figure 3 and Figure 4 As shown, the inner width of the rectangular tube 4012 is larger than the outer diameter of the straight tube 4011, and the interior of the rectangular tube 4012 is a relatively regular shape, providing sufficient space for the subsequent rotation of the blade agitator 5036. The inner width of the contraction tube 4013 gradually decreases from one end close to the rectangular tube 4012 to the other end, so that when the water is transported from the rectangular tube 4012 and the contraction tube 4013 to the middle section of the conduit 403, the flow rate of the water increases, so that it can be better mixed with the repair agent added in the rectangular tube 4012, thereby promoting chemical reactions and effects.

[0041] Embodiment 4

[0042] Under normal circumstances, the pipe for discharging the liquid repair agent inside the delivery mechanism 5 needs to be kept in a cleared state at all times to facilitate the export and transfer of the liquid repair agent. However, in this case, the amount of liquid repair agent used is large. Therefore, in order to control the amount of repair agent delivered without using an electrical control device, Figure 1 , Figure 3and Figure 5 As shown, the delivery mechanism 5 includes a liquid storage tank 501 installed on the lifting frame 1. The liquid storage tank 501 is consistent with the prior art and also has a function of providing the remaining liquid level, so as to remind the staff to add as soon as possible when the internal liquid repair agent is about to run out. A liquid conduit 502 extending to the inside of the rectangular tube 4012 is connected to the bottom of the liquid storage tank 501, and a control valve 5021 is installed on the liquid conduit 502. A control component 503 for rotating under the impact of the water body in the rectangular tube 4012 is installed at the tail end of the liquid conduit 502. In actual application, the control valve 5021 is in a normally open state, so that the liquid repair agent inside the liquid storage tank 501 flows down along the liquid conduit 502 to the space inside the rectangular tube 4012, and at the same time cooperates with the control component 503 to intermittently open the bottom opening of the liquid conduit 502, thereby effectively reducing the amount of liquid repair agent used.

[0043] Specifically, the control component 503 includes a plugging head 5031 fixedly mounted on the inner wall at the bottom of the liquid conduit 502, a fan-shaped slot 5032 is provided on the plugging head 5031, a mosaic column 5033 is rotatably connected to the bottom of the plugging head 5031, a circular plate 5034 with a diameter larger than the inner diameter of the liquid conduit 502 is integrally mounted on the bottom of the mosaic column 5033, a through groove 5035 consistent with the shape and size of the slot 5032 is provided on the circular plate 5034, and a blade agitator 5036 located inside the rectangular tube 4012 is fixedly mounted in the middle of the bottom surface of the circular plate 5034. When the water pump 3 is operated to pump the water inside the double-layer trash can 2 into the rectangular tube 4012, the water flow will produce an impact force on the blade agitator 5036. Since the stirring blades in the blade agitator 5036 are inclined at 30°-45° and the blade shape is relatively wide, the pressure difference generated by the water flow on the blades will cause the blades to be acted upon by force, thereby causing the overall structure composed of the circular plate 5034 and the mosaic column 5033 to continue to rotate along the sealing head 5031. The rotation of the circular plate 5034 will cause the through groove 5035 to overlap with the notch 5032 intermittently. When the two overlap, it means that the outlet at the bottom of the liquid conduit 502 is open. At this time, the liquid repair agent will flow downward without hindrance and mix with the water flowing from the rectangular tube 4012 to the contraction tube 4013. On the contrary, when the position of the circular plate 5034 other than the through groove 5035 overlaps with the notch 5032, the outlet at the bottom of the liquid conduit 502 will be blocked, and the liquid repair agent will basically not be discharged downward. Based on this, the amount of repair agent used can be effectively reduced, thereby reducing costs.

[0044] Embodiment 5

[0045] In the first embodiment, the water filtered by the double-layer trash can 2 will be pumped away by the water pump 3 and enter the annular tube 402, and finally discharged from the outlet on the annular tube 402. However, since the water extracted by the water pump 3 contains a small amount of impurities, it is easy to cause the outlet end of the annular tube 402 to be blocked. In order to effectively solve this problem, Figure 1 and Figure 6 As shown, the aeration assembly 6 includes an aerator 601 installed on the top of the liquid storage tank 501, and a vent pipe 602 extending to the top of the center of the annular tube 402 is connected to the output end of the aerator 601, and a plurality of branch air guide pipes 603 connected to the inner wall of the annular tube 402 are connected to the tail end of the vent pipe 602. The branch air guide pipes 603 are inclined from bottom to top from one end in contact with the annular tube 402 to the other end. The extension direction of the branch air guide pipes 603 and the branch liquid guide pipes 404 are both located at the inlet of the large-pore slot aeration head 405. The aerator 601 introduces low-pressure air into the branch air guide pipes 603, and bubbles are collected in the large-pore slot aeration head 405 and discharged to achieve water flow disturbance, so that the introduced air and water are finally collected in the large-pore slot aeration head 405 and discharged. The aerator 601 is used to introduce low-pressure air into the branch air duct 603 to promote the mixing and reaction of the liquid repair agent with the substances in the water body. On the one hand, the disturbance of air bubbles can make the repair agent better dispersed in the water body, increasing the contact area between the repair agent and the target substance; on the other hand, for some redox repair agents, the presence of oxygen may change the redox potential of the water body, thereby affecting the reaction activity and reaction direction of the repair agent, and enhancing the removal effect of the repair agent on pollutants. In addition, the bubbles and water flow disturbances generated by the introduction of air can effectively prevent impurities from statically gathering inside the large-pore slot aeration head 405, thereby effectively avoiding blockage on the large-pore slot aeration head 405.

[0046] like Figure 1 and Figure 7As shown, the double-layer trash can 2 includes a slider 201 sleeved on the lifting frame 1, a protective outer cylinder 202 located above the annular tube 402 is installed on one side of the slider 201, a sinking and floating inner cylinder 203 is arranged inside the protective outer cylinder 202 to float up and down, and a filter screen cylinder 204 is placed inside the sinking and floating inner cylinder 203. This double-layer trash can 2 is a prior art, and the slider 201, protective outer cylinder 202, sinking and floating inner cylinder 203 and filter screen cylinder 204 described are basic structures, and other related structures are not described in detail here. It is intended that in actual application, by running the water pump 3, the water inside the protective outer cylinder 202 is continuously extracted, and when the upper end of the sinking and floating inner cylinder 203 sinks to a position below the water surface, the external water will flow into the interior from the upper end of the sinking and floating inner cylinder 203, and at the same time, the garbage on the water surface floats into the filter screen cylinder 204 in the sinking and floating inner cylinder 203 with the water flow. The water volume changes between the water inside the protective outer cylinder 202 and the water flowing into the top of the sinking and floating inner cylinder 203 by the water pump 3, so that the sinking and floating inner cylinder 203 can move up and down in the protective outer cylinder 202, so as to adapt to the collection of different floating garbage of different sizes on the water surface.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
