Technical Field

[0001] This utility model relates to the field of river purification technology, specifically to an urban river ecological purification device. Background Technology

[0002] River ecosystems encompass all environmental and biological elements within the river and its riparian zone. Urban rivers play a vital role in flood control and drainage, groundwater replenishment, biodiversity conservation, and improving the local urban microclimate. However, urbanization generally has negative impacts on river ecosystems, such as runoff disturbance, water quality deterioration, and ecosystem degradation. Numerous environmental problems caused by urban river pollution are gradually becoming key constraints on sustainable urban economic development.

[0003] Existing methods for maintaining urban river ecosystems mainly involve setting up interception nets in river channels to intercept garbage. This method of river ecological purification is simplistic. If purification agents need to be added, they must be added manually by boat, which is time-consuming and labor-intensive. Furthermore, the manual addition of agents only involves contact with the upper water layer, resulting in uneven mixing between the agents and the river water and affecting the purification effect. Utility Model Content

[0004] The purpose of this invention is to provide an ecological purification device for urban rivers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an urban river ecological purification device, comprising a debris-blocking floating raft, an aeration assembly, and a chemical dosing assembly. The debris-blocking floating raft is composed of multiple sets of floats connected in series, and each set of floats has a debris-blocking grid installed at its lower end. The aeration assembly includes an air inlet pipe, the outlet of which is connected to a main air supply pipeline. The main air supply pipeline is connected to multiple branch pipes, and each branch pipe is connected to an aeration pipe. The chemical dosing assembly includes a liquid inlet pipe, the outlet of which is connected to a main liquid supply pipeline. The main liquid supply pipeline is connected to multiple sets of chemical dosing pipes, and each set of chemical dosing pipes is equipped with multiple sets of nozzles.

[0006] Furthermore, the multiple sets of the diversion pipes are evenly distributed at intervals along the length of the main gas supply pipeline.

[0007] Furthermore, the drug dosing tubes are evenly distributed at intervals along the length of the main liquid delivery pipeline.

[0008] Furthermore, the multiple sets of nozzles are evenly distributed at intervals along the height direction of the drug dosing pipe.

[0009] Furthermore, both ends of the debris-blocking floating raft are equipped with fixing ropes for securing the raft to the shore.

[0010] Furthermore, the aeration assembly is fixed to the support structure on the shore by a first fixing frame.

[0011] Furthermore, the inlet of the aeration component is connected to an external aerator.

[0012] Furthermore, the drug dosing assembly is fixed to the support structure on the shore by a second fixing frame.

[0013] Furthermore, the inlet of the drug dosing component is connected to an external drug storage tank via a pump body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention comprises a floating debris interceptor, an aeration assembly, and a chemical dosing assembly, which together constitute a river ecological purification device to achieve comprehensive purification of urban rivers. The floating debris interceptor effectively intercepts floating debris such as driftwood, branches, leaves, weeds, garbage, and ice in urban river channels. The aeration assembly aerates and decomposes and oxidizes pollutants in the water, increasing the dissolved active oxygen content. The chemical dosing assembly periodically adds purification agents to the urban river, where the agents mix with the water and react to improve and restore the ecological environment of the urban river.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an urban river ecological purification device, including a floating debris interceptor 1, an aeration component 2, and a chemical dosing component 3. The floating debris interceptor 1, the aeration component 2, and the chemical dosing component 3 together constitute a river ecological purification device to achieve comprehensive purification of urban rivers.

[0025] Furthermore, the debris-blocking floating raft 1, the aeration assembly 2, and the chemical dosing assembly 3 are all independently installed yet work together, facilitating subsequent maintenance. The debris-blocking floating raft 1 comprises multiple sets of pontoons 11 connected in series. Each set of pontoons 11 is fixedly connected to a debris-blocking grid 12 at its lower end. The debris-blocking grid 12 intercepts floating debris such as driftwood, branches, leaves, weeds, garbage, and ice in urban rivers and waterways, improving the efficiency of cleaning floating garbage and reducing the labor intensity of manual dredging.

[0026] Aeration component 2 is connected to an aerator. Aeration component 2 includes an air inlet pipe 21. The outlet of the air inlet pipe 21 is connected to a main air supply pipe 22. Multiple branch pipes 23 are connected to the main air supply pipe 22. The branch pipes 23 are evenly distributed along the length of the main air supply pipe 22. The outlet end of each branch pipe 23 is connected to an aeration pipe 24.

[0027] Aeration via aeration component 2 decomposes and oxidizes pollutants in the water, increases dissolved active oxygen levels, purifies the water, and restores and enhances the water's self-purification capacity. The aerator is a nano-aerator; nano-bubbles have a high oxygen transfer rate, producing more dissolved oxygen and achieving higher biochemical oxygen demand (BOD) and ammonia nitrogen removal rates. Furthermore, the branch pipes 23 are evenly distributed along the length of the main air supply pipe 22, ensuring multiple aeration pipes 24 are evenly distributed on the riverbed. This provides ample airflow, accelerating the oxidation and decomposition of organic matter and harmful substances such as nitrite deposited at the bottom of the water, and carrying harmful and toxic gases to the surface, thereby improving and stabilizing water quality.

[0028] The aeration component 2 is fixed to the bank support structure by the first fixing frame 25. Multiple sets of aeration components 2 can be arranged at intervals according to actual use needs, and the river can be fully aerated through multiple sets of aeration components 2.

[0029] The reagent dosing assembly 3 includes an inlet pipe 31, which is connected to a main liquid delivery line 32. The main liquid delivery line 32 is connected to multiple sets of reagent dosing pipes 33. Multiple sets of nozzles 331 are provided on the reagent dosing pipes 33, and the purification reagent is finally sprayed out through the multiple sets of nozzles 331 of the reagent dosing pipes 33.

[0030] Furthermore, multiple sets of nozzles 331 are evenly distributed at intervals along the height direction of the agent dosing pipe 33, and each set of nozzles 331 faces a different direction. When spraying the purification agent, the contact area between the agent and the water can be increased, thereby improving the purification effect on the water.

[0031] Purification agents are periodically added to urban rivers through the agent dosing component 3. The liquid agent enters the main liquid delivery pipeline 32 through the inlet pipe 31, and then is distributed to each agent dosing pipe 33 through the main liquid delivery pipeline 32. A certain amount of agent is added to the water through the agent dosing pipe 33. The agent mixes with the water and reacts to improve and restore the ecological environment of urban rivers.

[0032] The floating debris barrier 1 is equipped with fixing ropes 13 at both ends. The fixing ropes 13 are set on the outermost buoy 11, and multiple sets of buoys 11 are connected in parallel. The debris-blocking grids 12 at the lower end of the buoys 11 are arranged in parallel to form a debris-blocking net structure, which intercepts solid waste and floating objects in urban rivers. The floating debris barrier 1 is fixed to the bank by the fixing ropes 13, which secure the entire floating debris barrier 1, allowing it to span the river and comprehensively intercept various solid wastes in the river.

[0033] The chemical dosing assembly 3 is fixed to the bank support structure by the second fixing frame 34. Multiple sets of chemical dosing assemblies 3 can be arranged at intervals according to actual use needs. The river can be fully dosed with chemicals by multiple sets of chemical dosing assemblies 3, which replaces manual dosing by boat, saving time and effort and reducing labor intensity.

[0034] The agent dosing assembly 3 is connected to the pump body, which serves as the power source. The pump body is connected to the agent storage tank, which stores a certain amount of purification agent in advance. When the pump body is working, it draws out the agent from the agent storage tank and sends it into the agent dosing assembly 3, which then performs the agent dosing operation.

[0035] Working principle: In use, the debris-blocking floating raft 1, aeration component 2, and chemical dosing component 3 together constitute a river ecological purification device. Aeration component 2 is fixed to the bank support structure by the first fixing frame 25, and chemical dosing component 3 is fixed to the bank support structure by the second fixing frame 34. Debris-blocking floating raft 1 is fixed to the bank by fixing rope 13. Aeration component 2 is connected to a nano aerator. Debris-blocking floating raft 1 can cross the river channel and effectively intercept floating debris such as driftwood, branches, leaves, weeds, garbage, and floating ice in urban rivers.

[0036] Aeration is achieved through aeration component 2, which decomposes and oxidizes pollutants in the water, increases the amount of dissolved active oxygen in the water, purifies the water, restores and enhances the water's self-purification capacity. Multiple aeration pipes 24 are evenly distributed on the riverbed, with sufficient airflow, which can accelerate the oxidation and decomposition of organic matter and harmful substances such as nitrite deposited at the bottom of the water body, and can also carry harmful and toxic gases to the surface, thereby improving and stabilizing water quality.

[0037] Purification agents are periodically added to urban rivers through the agent dosing component 3. The agents mix with the water and react to improve and restore the ecological environment of urban rivers.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
