[0002] Filtration technology, as an ancient and important conventional treatment process in water treatment, plays a vital role in improving water quality. In daily life and industrial production, filtration technology can effectively reduce the turbidity in water and ensure the safety and cleanliness of water quality. In the filtration process, filter media is a key material. Generally speaking, any medium used for filtration can be collectively referred to as filter media. When water flows through the filter layer composed of filter media layers, impurities in it, such as suspended particles, organic matter and microorganisms, will be intercepted by the filter layer.

These devices will gradually accumulate a large amount of pollutants during long-term use. These pollutants will not only reduce the filtering effect of the filter material, resulting in the inability to effectively improve the quality of the river water, but also may cause poor water flow, further exacerbating the ecological problems of the river. Therefore, how to design a river water filtration device that can be cleaned regularly and maintain a stable filtering effect has become an urgent problem to be solved. Utility Model Content

[0028] The moving mechanism comprises a track 1, a net box 2 and a pulley block 4; a plurality of pulley blocks 4 are fixedly provided at the bottom of the net box 2, and the pulley bodies of the pulley blocks 4 are placed on the track 1 so as to move along the track 1 laid on the bank slope and the river bottom;
[0029] The net box 2 is a coverless box, and a plurality of holes are arranged on the two sides of the box located at the upstream and downstream, so that the river water from the upstream flows into the downstream through the holes on the side of the net box 2, thereby realizing the circulation of the river water. A filtering assembly for filtering the river water is arranged inside the net box 2.
[0030] Preferably, at least one of the net boxes 2 is arranged on the same track 1 along the length direction of the track; when the river channel is wide, multiple net boxes 2 are arranged on the same track 1 along the length direction of the track, and the net boxes 2 are connected by a detachable connecting structure 6. The total length of the multiple net boxes 2 matches the width of the river channel, thereby increasing the contact area between the net boxes 2 and the river water and further improving the filtering effect; when the river channel is narrow, one net box 2 is arranged on the same track 1 to ensure the filtering effect of the river water while reducing the cost.
[0031] Preferably, at least two sets of pulley blocks 4 are evenly arranged at the bottom of the net cage 2, and the number of pulley blocks 4 increases or decreases according to the size of the net cage 2; when the river channel is wider, the size of the net cage 2 increases, and the number of pulley blocks 4 increases accordingly; when the river channel is narrower, the size of the net cage 2 becomes smaller, and the number of pulley blocks 4 decreases accordingly.
[0032] Preferably, a handle 5 is provided on the side of the net cage 2 close to the river bank; when the net cage 2 needs to be moved, the staff can pull the net cage 2 out of the river channel or put it into the river channel by the handle 5, which facilitates the staff's operation.
[0033] Further preferably, the handle 5 is of an embedded type. The surface of the embedded handle is smooth, and it is not easy for matter to accumulate. It is also very convenient to clean and has a hygienic advantage.
[0034] The side wall of the net box 2 is provided with a connecting structure 6. When the number of the net boxes 2 is greater than 1, the net boxes 2 are connected by the connecting structure 6.
[0035] Further preferably, the connection structure 6 is a magnet block, the magnet blocks of adjacent mesh boxes 2 have opposite magnetic properties, and the connection of adjacent mesh boxes 2 is achieved through mutual force.
[0036] The pulley block 4 includes a pulley and a connecting rod 7 arranged perpendicular to the track 1. The pulleys are symmetrically installed at both ends of the connecting rod 7, and the pulley moves along the track 1; the connecting rod 7 is connected to a vertical rod arranged in the middle position of the bottom surface of the net box 2, the upper end of the vertical rod is vertically fixed to the bottom surface of the net box 2, and the lower end of the vertical rod is vertically fixed to the middle of the connecting rod 7. The movement of the pulley can drive the net box 2 to move.
[0037] The track 1 is a double track, which cooperates with the pulley block 4; the track spacing is the same as the pulley spacing.
[0038] Preferably, at least one row of tracks 1 is arranged along the direction of the water flow 9, and the mesh boxes 2 and the filter components are placed on a plurality of tracks 1 arranged side by side, thereby improving the filtering effect.
[0039] The filter assembly includes a filter box 3 and aquatic plants 8; filter material is placed inside the filter box 3, and a layer of planting soil for planting aquatic plants 8 is laid on the filter material; the filter box 3 is placed in the net box 2.
[0040] The filter box 3 is provided with a plurality of holes on the two sides located at the upstream and downstream. The river water from the upstream flows through the holes on the sides of the filter box 3 and then passes through the filter material and enters the downstream, thereby filtering the river water.
[0041] The filter media placed inside the filter box 3 include materials with porous structures and purification and filtering functions such as sand, carbon, alumina, and fiber, which separate solid particles from river water; filter media of different particle sizes mainly rely on pore adsorption to filter and purify river water.
[0042] The aquatic plants 8 are planted on the planting soil, and the roots of the aquatic plants 8 are distributed in the planting soil and the filter material. The roots distributed underwater absorb organic pollutants such as ammonia, nitrogen, and phosphorus in the river water, convert them into their own nutrients, and grow.
[0043] Preferably, in northern my country, flowering plants such as Lythrum salicina, aquatic canna, and aquatic iris can be planted to improve the viewing effect; plants with strong adsorption capacity such as calamus, reed, and cattail can also be planted to improve the absorption effect of organic pollutants such as ammonia, nitrogen, and phosphorus in river water. In southern my country, more types of plants can be planted, such as aquatic plants with strong adsorption capacity such as water lily, water plantain, and water spinach, which bloom and have good landscape effects; the gaps between aquatic plants 8 provide fish with a habitat, which is conducive to fish reproduction and increases biodiversity.
[0044] Working principle:
[0045] A filter box 3 is placed in the net box 2. The filter material is placed in the lower layer of the filter box 3 for filtering river water, and planting soil is laid on the upper layer of the filter material for planting aquatic plants 8. The filter box 3 is placed in the net box 2 with a pulley block 4. The pulley block 4 and the track 1 laid on the bank slope and the riverbed are used to place the net box 2 in the river channel to achieve the purpose of mobility.
[0046] The river water flows from top to bottom through the filter box 3 in the river channel, and the solid particles are trapped in the pores of the filter material. The filtered river water flows downstream, effectively purifying the water quality. A multi-channel filtering structure is set, that is, multiple rows of tracks 1 are set along the direction of the water flow 9, and the net boxes 2 and filter boxes 3 are placed on multiple parallel tracks 1 to improve the filtering effect of the river water and improve the downstream water quality. At the same time, the aquatic plants 8 planted in the filter box can absorb pollutants such as ammonia, nitrogen, and phosphorus in the river channel, convert them into their own nutrients and grow, further improving the water quality. The dual purification functions of the filter material and the aquatic plants 8 achieve the purpose of purifying the water body, promoting the ecological diversity of the river, and improving the ornamental value.
[0047] The net cage 2 and filter box 3 are cleaned regularly every two years. The staff pulls the handle 5 on the side of the net cage 2 and pulls the net cage 2 out of the river channel to the river bank along the track 1, and washes the net cage 2 and filter box 3 with a high-pressure water gun to remove impurities in the filter material and reuse it and put it into the filter box 3; the net cage 2 and filter box 3 are then returned to the river channel via the track 1 to achieve the purpose of recycling the filter box 3 and the filter material. Supplementary planting is carried out according to the growth of aquatic plants 8 to provide a habitat for fish, which is conducive to fish reproduction and increases biodiversity.
