Description

Technical Field

[0001] This application relates to a floating pollutant removal device for rivers. Background Technology

[0002] To divert water from rivers, lakes, seas, and reservoirs to farmland and other areas requiring water, canals are now commonly used. To ensure water level stability within these canals, underwater weirs are typically installed to control the water level. However, white pollutants, leaves, and other debris can accumulate on the surface of these canals, causing floating pollution. Currently, manual removal is the primary method, but this is inefficient and labor-intensive. Therefore, it is necessary to perform preliminary treatment of the floating debris to improve removal efficiency. Utility Model Content

[0003] To address the aforementioned problems, this application proposes a floating pollutant removal device for rivers, comprising an underwater weir platform, several support rods mounted above the weir platform, a diversion section mounted on each support rod, and several jet nozzles mounted on the diversion section. Lateral baffles are mounted on both sides of the underwater weir platform, and lateral flow channels are positioned on the lateral baffles corresponding to the positions of the underwater weir platform. A filter screen is installed within the lateral flow channels. This application utilizes the jet nozzles on the diversion section to blow floating debris from the river, causing it to be continuously guided towards the lateral flow channels of the lateral baffles under the action of the jet nozzles and the water flow. This allows for the collection of floating debris within the lateral flow channels, which can then be removed by workers, improving work efficiency.

[0004] Preferably, an enlarged channel is provided in the direction of the lateral flow channel toward the upstream of the river.

[0005] Preferably, the diversion section includes a bottom support pipe connected to a support rod, a V-shaped pipe communicating with the bottom support pipe on the side of the bottom support pipe facing upstream of the river, and an external connecting pipe connected to an external air source on the bottom support pipe or the V-shaped pipe; a plurality of first air nozzles facing upstream or diagonally towards the river are provided on the V-shaped pipe, and a plurality of second air nozzles facing downstream or diagonally towards the river are provided on the bottom support pipe. The frame portion of the diversion section of this application includes the bottom support pipe and the V-shaped pipe, so that floating objects do not accumulate in the middle, but are moved from the middle to both sides, completing the collection of floating pollutants to the sides.

[0006] Preferably, a plurality of intermediate support pipes are provided between the V-shaped pipe and the bottom support pipe, a plurality of third air nozzles obliquely arranged to the left are provided on the intermediate support pipe located on the left side, and a plurality of fourth air nozzles obliquely arranged to the right are provided on the intermediate support pipe located on the right side.

[0007] Preferably, a central tube is provided between the middle of the V-shaped tube and the middle of the bottom support tube, a number of central tube right nozzles are provided on the right side of the central tube at an angle to the right, and a number of central tube left nozzles are provided on the left side of the central tube at an angle to the left.

[0008] Preferably, the support rod includes a bottom connecting plate connected to the underwater weir platform, a vertical support rod body is provided on the bottom connecting plate, and an L-shaped connecting rod is provided on the upstream side of the vertical support rod body. The other end of the L-shaped connecting rod is fixedly connected to the upper part of the bottom support pipe. This application uses an L-shaped connecting rod to hang the diversion section upside down on the water surface, which can avoid obstructing floating objects on the water surface and allow the floating objects to be quickly collected in the lateral flow channel.

[0009] Preferably, the second air nozzle is oriented diagonally to the left of the central tube and diagonally to the right of the central tube.

[0010] This application can bring the following beneficial effects:

[0011] 1. This application utilizes jet nozzles on the diversion section to blow floating objects on the river, causing them to be continuously guided towards the lateral flow channel of the lateral baffle under the action of the jet nozzles and water flow. This allows the floating objects to be collected in the lateral flow channel, and then the workers can remove the pollutants from the lateral flow channel, thus improving work efficiency.

[0012] 2. The frame portion of the diversion section of this application includes a bottom support tube and a V-shaped tube, so that floating objects do not accumulate in the middle, but are moved from the middle to both sides, thus completing the collection of floating pollutants to the sides.
