Description

Technical Field

[0001] The utility model belongs to the technical field of ecological restoration, and specifically relates to a diversion frame, a filtering component and a river water pollution ecological restoration device. Background Art

[0002] Floating garbage on the water surface seriously affects water quality and the ecosystem. There are various types, including domestic garbage, vegetation garbage, mining industry garbage, aquatic plants, etc. The cleaning methods include manual cleaning, net fishing, bottom sediment sewage discharger, biological treatment, chemical treatment, and floating trash cans on the water. The floating trash cans on the water adopt automatic collection technology and have multiple intelligent functions, improving the cleaning efficiency and reducing the labor cost. It is crucial to protect the water body cleanliness and the stability of the ecosystem.

[0003] Among them, aquatic plants (such as waterweeds, duckweeds, cyanobacteria, etc.) will also become floating garbage on the water surface when growing excessively.

[0004] Algae floating on the water surface usually refer to those algae that can suspend or float on the water surface for photosynthesis. These algae are widely present in nature and have important impacts on the water environment and aquatic organisms. Positive impacts: As primary producers, the algae floating on the water surface provide important organic matter and oxygen sources for the aquatic ecosystem; they are the food sources of many aquatic animals and play an important role in maintaining aquatic biodiversity and the stability of the food chain. Negative impacts: When the algae overgrow to form algal blooms, they will consume a large amount of dissolved oxygen in the water, leading to water quality deterioration and affecting the survival of other aquatic organisms; some algae will release toxic substances (such as hydroxylamine, hydrogen sulfide, etc.) after death, posing threats to aquatic organisms and human health.

[0005] The phenomenon of algal blooms will also affect the aesthetics and use value of the water body (such as drinking water sources, fishery resources, etc.). When algal blooms occur in large numbers, a thick green algal layer will form on the water surface, which can release toxins - lake indigo, which is toxic to fish. After the algae die, rot, and decompose, they consume a large amount of dissolved oxygen in the water, making the water body produce a foul smell, not only destroying aquatic resources but also affecting the aesthetics and recreation of the water body. The algae on the water surface mostly appear in filaments, and when there are more filaments and they are entangled and condensed, they become flocs. In the prior art, for the floating algae in the form of filaments, only manual or ship salvage collection can be carried out. The above treatment methods not only have a large workload but also are limited in operation time. Summary of the Utility Model

[0006] In order to solve the problems that the collection operation amount of filamentous algae on the river surface is large and the operation time is affected, the utility model provides a diversion frame, a filtering component and a river water pollution ecological restoration device.

[0007] The utility model is realized by the following technical solutions:

[0008] A flow guide frame comprises a first mounting plate, one side of which is evenly distributed with a plurality of guide rods with smooth surfaces; the guide rod comprises a straight rod section and a raised section, one end of the support rod is connected to the first mounting plate, and the other end is connected to the raised section; the guide rod is inclined in a direction away from the first mounting plate and toward a water flow; the raised section is arched upward as a whole; the axis lines of the straight rod section, the raised section and the transition section of the same guide rod are all in the same plane.

[0009] The first mounting plate is tilted and fixed on the bank of the river, so that multiple guide rods are gradually raised along the direction of the water flow, and the axis lines of the guide rods are all in the same vertical plane, and it is ensured that multiple guide rods are above the water surface. When filamentous algae pass through the guide frame with the water flow, they can be intercepted by the guide rods, and under the push of the water flow, the algae slide along the straight rod section to the raised section, and accumulate at the raised section for subsequent centralized processing; by placing the guide frame, the interception of filamentous algae can be completed without being affected by the operation time and reducing the work efficiency.

[0010] A further improvement of the utility model is that the guide rod further comprises a transition section, which connects the straight rod section and the raised section. When the intercepted algae increases, the algae gradually move from the transition section to the raised section under the impact of the water flow.

[0011] A filter assembly includes a second mounting plate, a filter box and a guide frame; the second mounting plate is arranged on the side of the ridge section away from the first mounting plate, the filter box is installed on the side of the second mounting plate close to the ridge section, and the top surface of the filter box is provided with an opening; a first notch for supporting the ridge section is provided on the side wall of the filter box close to the guide rod, and the ridge section extends into the filter box through the first notch; the filter box is uniformly provided with blocking members capable of collecting filamentous algae. The ridge section extends into the filter box through the first notch, and the first notch forms a hook support for the ridge section; when the algae enters the filter box along the ridge section, the algae is collected by the blocking member; when in use, multiple filter assemblies can be connected in sequence and intercepted at the narrowest part of the river surface, and in order to ensure that several guide rods close to the water flow and one end of the filter box are below the water surface, a counterweight block can be added to the first mounting plate and the end of the filter box close to the water flow, so that the filamentous algae can be intercepted by the filter assembly.

[0012] A further improvement of the utility model is that the barrier is a hook-shaped structure that bends toward one side toward the water flow, which helps to improve the collection of algae.

[0013] A further improvement of the utility model is that a drain port is provided on the side wall of the filter box near the direction of water flow, so that the water entering the filter box can flow out through the drain port to reduce the resistance of the filter box.

[0014] An ecological restoration device for river water pollution, comprising an impeller, a wheel shaft, a roller and a filtering component; support members are respectively arranged at the front and rear ends of the filtering box, the second mounting plate is connected with the wheel shaft through the support members, and the wheel shaft rotates on the support members; an impeller is arranged at one end of the wheel shaft close to the water flow direction, a roller is arranged below the raised section, the roller is sleeved on the wheel shaft, and a brush is arranged on the roller. Under the impact of the water flow, the impeller drives the roller to rotate clockwise, and the brush stirs the algae accumulated on the raised section into the filtering box, improving the collection efficiency of the algae.

[0015] A further improvement of the present utility model is that the axis line of the straight rod section is perpendicular to the side wall of the filtering box where the first notch is opened, and the axis line of the wheel shaft is parallel to the side wall of the filtering box where the first notch is opened. This makes the roller fit with multiple raised sections, ensuring that the brush can keep in contact with multiple raised sections.

[0016] A further improvement of the present utility model is that a plurality of second notches capable of cooperating with the brush are also opened on the side of the filtering box close to the roller. Through the cooperation of the second notch and the brush bristles, the collection of algae and other floating impurities attached to the brush bristles into the filtering box is completed.

[0017] A further improvement of the present utility model is that the width of the second notch is smaller than the width of the first notch. This improves the collection efficiency of the impurities on the brush bristles.

[0018] A further improvement of the present utility model is that the impeller is a Pelton wheel. This helps to improve the rotation efficiency of the roller.

[0019] From the above technical solutions, it can be seen that the beneficial effects of the present utility model are as follows: the first mounting plate is fixedly inclined on the bank of the river, so that a plurality of guide rods gradually rise along the water flow direction, and the axis lines of the guide rods are all in the same vertical plane, and it is ensured that a plurality of guide rods are above the water surface. When the filamentous algae pass through the guide frame along with the water flow, they can be intercepted by the guide rods, and under the action of the water flow, the algae slide along the straight rod section to the raised section and accumulate at the raised section for subsequent centralized treatment; through the placement of the guide frame, the interception of the filamentous algae can be completed, which is not affected by the operation time and reduces the work efficiency.

Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent.

[0033] As shown in the atta Figures 1-10As shown, an ecological restoration device for river water pollution includes an impeller 6, a wheel shaft 61, a roller 5 and a filtering component; the impeller 6 is driven by the water flow to drive the roller 5 to push the floating algae on the water surface towards the filtering component for collection. Support members 41 are respectively arranged at the front and rear ends of the filtering box 3, the second mounting plate 4 is connected to the wheel shaft 61 through the support members 41, and the wheel shaft 61 rotates on the support members 41 through bearings; an impeller 6 is arranged at one end of the wheel shaft 61 close to the water flow direction, and the impeller 6 is a Pelton wheel; this helps to improve the rotation efficiency of the roller 5. A roller 5 is arranged below the raised section 22, the roller 5 is sleeved on the wheel shaft 61, and a brush 51 is arranged on the roller 5. The impeller 6 drives the roller 5 to rotate clockwise under the impact of the water flow, and the brush 51 stirs the algae accumulated on the raised section 22 into the filtering box 3, improving the collection efficiency of the algae.

[0034] The brush 51 is made by aggregating a batch of bristles; embedding grooves are evenly distributed on the surface of the roller 5, and a bristle bearing plate 511 is embedded in the embedding grooves, and the brush 51 is arranged on the bristle bearing plate 511. The brush 51 can be quickly replaced by replacing the bristle bearing plate 511.

This helps to improve the collection of algae. A drain port 34 is opened on the side wall of the filtering box 3 close to the water flow direction. This facilitates the water flow entering the filtering box 3 to flow out through the drain port 34, reducing the resistance of the filtering box 3.

[0036] The guide frame includes a first mounting plate 1 and a guide rod 2 which are arranged in sequence from left to right. A plurality of guide rods 2 are evenly distributed on one side of the first mounting plate 1. The surface of the guide rod 2 is a smooth structure for the algae to slide along it. The guide rod 2 includes a straight rod section 21 and a raised section 22. The guide rod 2 also includes a transition section 23, and the transition section 23 connects the straight rod section 21 and the raised section 22.

In order to ensure the interception effect of filamentous algae. In order to reduce the resistance of the filter box 3, a water hole can be opened on the filter box 3, and the collection efficiency of algae can be improved at the same time.

[0038] The second mounting plate 4 is arranged on the side of the raised section 22 away from the first mounting plate 1, and a first notch 31 for supporting the raised section 22 is opened on the side wall of the filter box 3 close to the guide rod 2, and the raised section 22 extends into the filter box 3 through the first notch 31; the raised section 22 extends into the filter box 3 through the first notch 31, and the first notch 31 forms a hooking support for the raised section 22; when algae enters the filter box 3 along the raised section 22, the algae is collected by the barrier 33; when in use, multiple filter components can be connected in sequence and intercepted at the narrowest part of the river surface. In order to ensure that several guide rods 2 close to the direction of water flow and one end of the filter box 3 are below the water surface, a counterweight block can be added to the first mounting plate 1 and the end of the filter box 3 close to the direction of water flow to facilitate the filamentous algae to be intercepted by the filter component.
