Description

Technical Field

[0001] This utility model relates to the field of river water purification technology, and in particular to a river water purification device based on an ecological filter wall. Background Technology

[0002] Ecological filter walls can effectively remove suspended solids, organic matter, and some nitrogen and phosphorus pollutants from water bodies through physical interception, adsorption, and biodegradation. At the same time, the micro-ecological environment created by the filter walls helps enhance the self-purification capacity of water bodies, achieving continuous purification and ecological restoration of river water quality.

[0003] Existing filter media (such as adsorption media and biological filter media) gradually reach saturation after long-term adsorption of impurities and interception of pollutants, rendering them ineffective in purification. Without a dedicated replacement mechanism, the filter media requires complete disassembly of the device, a complex and time-consuming process that leads to untimely replacement and prolonged "ineffective purification," failing to meet the needs of continuous river water quality improvement. Furthermore, in existing devices, filtration structures (such as filter screens and media) gradually accumulate sediment, suspended particles, and biological debris during river water interception, either adhering to the filter surface or clogging the filter pores. Without a cleaning mechanism, the accumulation of impurities significantly increases water flow resistance, potentially causing complete blockage and preventing normal water flow through the filter components, rendering the purification function essentially ineffective and unable to continuously intercept pollutants. Therefore, this paper proposes a river water purification device based on an ecological filter wall to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a river water purification device based on an ecological filter wall, which aims to improve the problems of complex and time-consuming filter material replacement and the difficulty in maintaining the purification function due to impurity accumulation obstructing water flow in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a river water purification device based on an ecological filter wall, comprising a float, wherein an outer shell is fixedly connected to the bottom outer wall of the float, a replacement mechanism is provided on the inner wall of the outer shell, and a cleaning mechanism is provided on the inner wall of the outer shell.

[0006] The replacement mechanism includes an outer frame, which is fixedly connected to the inner wall of the outer shell. A filter media box is detachably connected to the inner wall of the outer frame. A guide block is fixedly connected to the outer wall of the filter media box. A sliding block is slidably connected to the inner wall of the filter media box. A fixing buckle is slidably connected to the inner wall of the outer shell. A limit buckle is elastically connected to the inner wall of the outer shell by a spring. A connecting rod is fixedly connected to the outer wall of the limit buckle.

[0007] As a further description of the above technical solution: the cleaning mechanism includes a water pump, the water pump is fixedly connected to the housing, a filter sleeve is fixedly connected to the outer wall of the water pump inlet pipe, a filter screen is fixedly connected to the inner wall of the housing, and a spraying device is fixedly connected to the housing.

[0008] As a further description of the above technical solution: the outer wall of the fixing buckle is set as an arc, the inner outer wall of the fixing buckle is set as an inclined surface, and the outer wall of the sliding block is in contact with the inclined surface of the fixing buckle.

[0009] As a further description of the above technical solution: the inner wall of the outer frame is provided with a fixing slot, and the fixing buckle is engaged in the fixing slot.

[0010] As a further description of the above technical solution: the outer wall of the sliding block is provided with a limiting groove, and the limiting buckle is engaged in the limiting groove.

[0011] As a further description of the above technical solution: one end of the spring is fixedly connected to the inner wall of the connecting rod, and the other end of the spring is fixedly connected to the outer wall of the outer shell.

[0012] As a further description of the above technical solution: the filter screen is provided in three sets, and the outer walls of the three sets of filter screens are linearly distributed on the inner wall of the outer shell, and the spray device is located directly behind the filter screen.

[0013] As a further description of the above technical solution: the bottom water pipe of the water pump is the inlet pipe, and the side water pipe of the water pump is the outlet pipe.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, after the filter box is positioned and slid into the guide block inside the outer frame, the sliding block presses the inclined surface of the fixing buckle to make the fixing buckle engage in the fixing slot. At the same time, the connecting rod is pulled out to drive the limiting buckle. After the sliding block moves, the limiting buckle engages in the limiting slot of the sliding block under the action of the spring, thus completing the fixing of the filter box. This improves the problem of complicated and time-consuming filter replacement operation in the prior art.

[0016] 2. In this invention, when the water pump starts, its bottom inlet pipe draws river water. A filter sleeve outside the inlet pipe first filters out large particles of impurities in the water to prevent pump blockage. The pump then delivers the water to the side outlet pipe, and finally to the spraying device. Simultaneously, the river water flows through three sets of filter screens arranged in a straight line on the inner wall of the casing, where the screens intercept impurities in multiple stages. The spraying device, located directly behind the filter screens, sprays water under the power of the pump to wash away impurities adhering to the filter screen surface, ensuring continuous and efficient filtration and aiding in river water purification. This improves upon the problem in existing technologies where impurities accumulate and obstruct water flow, hindering the continuous purification function. Attached Figure Description

[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] Reference Figure 1 As shown, one embodiment of this utility model is a river water purification device based on an ecological filter wall, including a float box 1. The bottom outer wall of the float box 1 is fixedly connected to an outer shell 3. The outer shell 3 is connected to the float box 1 and accommodates a replacement and cleaning mechanism 4, providing installation support for the water purification components. The inner wall of the outer shell 3 is provided with a replacement mechanism 2, which facilitates quick and easy disassembly and assembly of the filter media box 21, ensuring timely replacement of the filter media to maintain the purification effect. The inner wall of the outer shell 3 is provided with a cleaning mechanism 4, which draws river water, filters impurities, and washes the filter screen 44 to ensure continuous and efficient water purification.

[0025] Reference Figures 2-3As shown, the replacement mechanism 2 includes an outer frame 29. A fixing slot 26 is provided on the inner wall of the outer frame 29. The outer frame 29 provides installation space for the filter media box 21. Together with guide blocks 23 and fixing buckles 28, it enables the filter media box 21 to be positioned and installed. The outer frame 29 is fixedly connected to the inner wall of the outer shell 3. The filter media box 21 is detachably connected to the inner wall of the outer frame 29. The filter media box 21 is loaded with filter media. When river water flows through it, the filter media adsorbs impurities, achieving water purification. A guide block 23 is fixedly connected to the outer wall of the filter media box 21. The guide block 23 is used to install the filter media box 21. During installation, the filter media box 21 is guided to ensure that it accurately enters the designated position on the outer frame 29. A sliding block 22 is slidably connected to the inner wall of the filter media box 21. The outer wall of the sliding block 22 contacts the inclined surface of the fixing buckle 28. A limit groove 210 is provided on the outer wall of the sliding block 22. When the sliding block 22 slides, it presses against the inclined surface of the fixing buckle 28, controlling the extension and retraction of the fixing buckle 28, and assisting in fixing or disassembling the filter media box 21. The inner wall of the filter media box 21 is slidably connected to the fixing buckle 28, and the outer wall of the fixing buckle 28 is rounded. The inner outer wall of the filter media box 21 is set as an inclined surface. The fixing buckle 28 is engaged in the fixing slot 26. The fixing buckle 28 is extended and retracted by the sliding block 22, engaging or disengaging from the fixing slot 26 to fix and unlock the filter media box 21. The outer wall of the fixing buckle 28 is provided with an auxiliary block to ensure the stability of the fixing buckle 28 sliding. The inner wall of the outer shell 3 is slidably connected to the limiting buckle 25, which is engaged in the limiting slot 210. The limiting buckle 25 engages in the limiting slot 210 to limit the sliding block 22 and assist in fixing the filter media box 21. 1. To prevent displacement, the limiting buckle 25 is elastically connected to the inner wall of the outer shell 3 via a spring 27. One end of the spring 27 is fixedly connected to the inner wall of the connecting rod 24, and the other end of the spring 27 is fixedly connected to the outer wall of the outer shell 3. The spring 27 provides elastic force to keep the limiting buckle 25 locked into the limiting slot 210, ensuring the limiting effect. The outer wall of the limiting buckle 25 is fixedly connected to the connecting rod 24. The connecting rod 24 connects the limiting buckle 25 and the spring 27, transmits the elastic force of the spring 27, and controls the extension and retraction of the limiting buckle 25.

[0026] Reference Figure 4As shown, the cleaning mechanism 4 includes a water pump 41. The bottom water pipe of the water pump 41 is the inlet pipe, and the side water pipe of the water pump 41 is the outlet pipe. The water pump 41 draws river water to provide power for the cleaning mechanism 4, while promoting water circulation and assisting in water purification. The water pump 41 is fixedly connected to the outer shell 3. A filter sleeve 42 is fixedly connected to the outer wall of the water pump 41 inlet pipe. The filter sleeve 42 filters the river water drawn in by the water pump 41, preventing large particles of impurities from entering the water pump 41 and causing blockage. A filter screen 44 is fixedly connected to the inner wall of the outer shell 3. The filter screen 44 is provided in three sets, and the outer walls of the three sets of filter screens 44 are linearly distributed on the inner wall of the outer shell 3. The filter screen 44 filters the river water in multiple stages, intercepting impurities in the water and further improving the water purification effect of the river. A spray device 43 is fixedly connected to the outer shell 3. The spray device 43 is located directly behind the filter screen 44. The spray device 43 sprays water under the action of the water pump 41 to wash the surface of the filter screen 44 and ensure the filtration efficiency of the filter screen 44.

[0027] When using this utility model, when installing the filter media box 21, after the filter media box 21 is positioned and slid into the guide block 23 inside the outer frame 29, the sliding block 22 presses the inclined surface of the fixing buckle 28 so that the fixing buckle 28 is engaged in the fixing slot 26. At the same time, the connecting rod 24 is pulled out to drive the limiting buckle 25. After the sliding block 22 moves, the limiting buckle 25 is engaged in the limiting slot 210 of the sliding block 22 under the action of the spring 27, thus completing the fixing of the filter media box 21. When disassembling, the connecting rod 24 is pulled to make the limiting buckle 25 disengage from the limiting slot 210, and the sliding block 22 is slid in the opposite direction, so that the fixing buckle 28 disengages from the fixing slot 26, and the filter media box 21 can be taken out.

[0028] When the cleaning mechanism 4 is working, the water pump 41 starts, and its bottom inlet pipe draws river water. The filter sleeve 42 outside the inlet pipe first filters out large particles of impurities in the water to prevent clogging of the water pump 41. The water pump 41 delivers the water to the side outlet pipe, and then to the spray device 43. At the same time, the river water flows through three sets of filter screens 44 arranged in a straight line on the inner wall of the outer casing 3. The filter screens 44 intercept impurities in multiple stages. The spray device 43 is located directly behind the filter screens 44. Powered by the water pump 41, it sprays water to wash away impurities attached to the surface of the filter screens 44, ensuring continuous and efficient filtration by the filter screens 44 and contributing to the purification of river water.
