[0002] River landscape is not only a common landscape form, but also an important ecological corridor and recreational resource, which has a very high value in environmental protection and tourism development. However, with the acceleration of industrialization and urbanization, the problem of river water pollution is becoming increasingly serious, and problems such as water body eutrophication, heavy metal pollution, and organic matter pollution are frequent, which has brought serious threats to the ecological environment. Traditional river water treatment methods often use manual salvage of garbage, chemical treatment, and physical filtration, but these methods have many limitations, such as low efficiency and high cost of manual salvage, the possibility of secondary pollution caused by chemical treatment, and the need for frequent replacement of filter materials due to physical filtration. In recent years, ecological purification technology has gradually become an important means of river water purification due to its environmental protection and sustainability, such as the patent with application number CN202211545387.X, which provides an ecological river water purification system, including a dike, a debris and algae removal device, and a water purification unit. The dike is located on one side of the river and extends obliquely from the riverbank to the river. The debris and algae removal device is located beside the head of the dike. The water purification unit is located on the riverbank beside the dike. The water purification unit includes a sand filter, a biochemical tank, a membrane filtration device, a clear water tank, and a nutrient salt adding system in sequence according to the water flow direction. The river water body is connected to the sand filter through the water inlet pipe. The sand filter is connected to the biochemical tank through the pipe. The biochemical tank is connected to the membrane filtration device through the pipe. The outlet of the membrane filtration device is connected to the clear water tank through the pipe. The other end is connected to the river through the drainage pipe. This invention can intercept non-point source pollution, reduce the concentration of pollutants in the river, and improve the purification capacity of the river. However, the system structure is complex, which is not conducive to later maintenance, and cannot achieve long-term water purification. SUMMARY

[0042] As Figure 1As shown, the embodiment of the present application provides a multi-component long-acting ecological filter device for purifying river water quality, which comprises an ecological filter assembly 1, a first mounting cover 2, a second mounting cover 3, an automatic cleaning water flow control mechanism 4, and a garbage collection net cage 5. The first mounting cover 2 is fixedly installed at the top front end of the ecological filter assembly 1, the second mounting cover 3 is fixedly installed at the top middle of the first mounting cover 2, the automatic cleaning water flow control mechanism 4 is arranged on the front of the ecological filter assembly 1, and the garbage collection net cage 5 is fixedly installed at the bottom of the ecological filter assembly 1. The ecological filter assembly 1 comprises an ecological filter core unit 102 internally provided with multiple layers of filter media, which can effectively remove suspended solids, organic matter, heavy metal ions and other pollutants in water. The automatic cleaning water flow control mechanism 4 continuously cleans the ecological filter core unit 102, prolonging the service life of the filter core. The garbage collection net cage 5 can collect the garbage cleaned from the ecological filter core unit 102 by the automatic cleaning water flow control mechanism 4, facilitating cleaning and avoiding secondary pollution of the river by the cleaned garbage, and further improving the effect of river purification and treatment. Through the cooperative work of each component, the overall purification efficiency and water purification effect are improved.

[0043] Specifically, as shown in the drawings, Figures 2-3 The ecological filter assembly comprises a mounting shell 101, an ecological filter core unit 102, a limiting guide chute 103, a movable net door 104, and a protective net 105. Among them

[0044] The mounting shell 101 provides a solid and closed space for the ecological filter core unit 102, protecting the ecological filter core unit 102 and ensuring that it can function stably;

[0045] The ecological filter core unit 102 is installed inside the mounting shell 101 and is the core part of the ecological filter assembly 1, which comprises a biochar filter layer 1021, a microbial agent sponge body filter layer 1022, and an iron-carbon composite material filter layer 1023 fixedly installed in sequence from front to back. The biochar filter layer 1021 can enhance the adsorption performance of the overall filter core and provide a habitat for microorganisms. The microbial agent sponge body filter layer 1022 is used to fix microbial agents. The iron-carbon composite material filter layer 1023 is used to realize electrochemical micro-electrolysis. Through multiple layers of filter media, physical, chemical, and biological triple purification mechanisms are realized, enhancing the purification effect.

[0046] The protective net 105 is fixedly installed on the front of the mounting shell 101 and can effectively intercept large-particle impurities and garbage, avoiding the blockage of the ecological filter core unit 102 by large-particle impurities and garbage.

[0047] The movable net door 104 is hingedly connected to the back of the installation shell 101, facilitating opening for regular inspection of the ecological filter core unit 102 for blockage and microbial activity, and replacement or replenishment of microbial agents if necessary, to ensure that all components of the ecological filter core device are working properly and continuously purifying the water quality of the river.

[0048] The limiting guide chute 103 is provided on the front of the installation shell 101 to provide a guide rail for the movement of the automatic cleaning water flow control mechanism 4.

[0049] As shown in Figures 4-5 The automatic cleaning water flow control mechanism 4 is used for automatic cleaning and water flow adjustment, and includes a servo motor 401, a first gear 402, a positive screw drive lead screw 403, a cleaning brush 404, a limiting guide rod 405, a second gear 406, a reverse screw lead screw 407, a connecting rod 408, a positive screw lead screw 409, a first lifting block 410, a first water flow adjustment valve plate 411, a first water flow adjustment valve plate 412, a second lifting block 413, a second water flow adjustment valve plate 414, and a second limiting guide sliding block 415.

[0050] The servo motor 401 is arranged at the top of the automatic cleaning water flow control mechanism 4, and its top is fixedly connected to the inner wall top of the second mounting cover 3. The bottom output end is sequentially movably penetrated through the bottom of the second mounting cover 3 and the inner wall top of the first mounting cover 2, and then the first gear 402 is fixedly installed. The servo motor 401 serves as a power source, and drives the operation of the entire system by rotating the first gear 402.

[0051] The bottom of the first gear 402 movably penetrates the bottom of the first mounting cover 2, and the positive screw drive lead screw 403 is fixedly installed at the bottom. The outer wall front end movably engages the second gear 406, which is used to transmit the rotating power of the servo motor 401 to the positive screw drive lead screw 403, and simultaneously engages the second gear 406 to achieve power distribution.

[0052] The bottom of the positive screw drive lead screw 403 is movably connected to the outer wall mounting shell 101 of the ecological filter assembly 1. The cleaning brush 404 is threadedly connected to the outer wall of the positive screw drive lead screw 403. The back of the cleaning brush 404 is movably connected to the front of the protective net 105 of the ecological filter core unit 102. The positive screw drive lead screw 403 drives the cleaning brush 404 to move up and down along its axis direction when it rotates, for cleaning the protective net 105.

[0053] The inner wall of the cleaning brush 404 is movably mounted with the limiting guide rod 405, the top of the limiting guide rod 405 is fixedly connected with the bottom of the first mounting cover 2, and the bottom is fixedly connected with the outer wall of the ecological filter assembly 1, so that the cleaning brush 404 is provided with stable guide and is limited in the movement path, and the cleaning brush 404 is prevented from deviating from the track during movement.

[0054] The second gear 406 is movably engaged with the outer wall front end of the first gear 402, the top of the second gear 406 is movably connected with the inner wall top of the first mounting cover 2, the bottom is movably penetrated through the bottom of the first mounting cover 2, and the reverse screw rod 407 is fixedly mounted, the second gear 406 is used for receiving the power transmitted by the first gear 402 and driving the reverse screw rod 407 to rotate. The bottom of the reverse screw rod 407 is fixedly mounted with the connecting rod 408, the bottom of the connecting rod 408 is fixedly mounted with the forward screw rod 409, and the pitch of the forward screw rod 409 is consistent with that of the reverse screw rod 407, but the rotation directions are opposite.

[0055] The reverse screw rod 407 is threadedly connected with the first lifting block 410, the front surface of the first lifting block 410 is fixedly mounted with the first water flow adjusting valve plate 411, the outer wall of the forward screw rod 409 is threadedly connected with the second lifting block 413, and the front surface of the second lifting block 413 is fixedly mounted with the second water flow adjusting valve plate 414. By rotating the reverse screw rod 407 and the forward screw rod 409, the first lifting block 410 and the second lifting block 413 move away from or towards each other on the screw rod, and the first water flow adjusting valve plate 411 and the second water flow adjusting valve plate 414 move with the lifting blocks to cooperatively adjust the size of the water flow channel, so that the water flow is adjusted.

[0056] The back surface of the first water flow adjusting valve plate 411 is fixedly mounted with the first limiting guide sliding block 412, and the outer wall of the first limiting guide sliding block 412 is slidably connected with the limiting guide sliding groove 103 in the inner wall of the mounting shell 101. The back surface of the second water flow adjusting valve plate 414 is fixedly mounted with the second limiting guide sliding block 415, and the outer wall of the second limiting guide sliding block 415 is slidably connected with the limiting guide sliding groove 103 in the inner wall of the mounting shell 101. The guide sliding groove provides stable guide for the limiting guide sliding block, ensures movement along the predetermined track, and the limiting guide sliding block moves in the guide groove to drive the water flow adjusting valve plate to open or close the water flow channel and adjust the water flow size.

[0057] The pitch of the reverse-thread screw 407 is smaller than that of the positive-thread drive screw 403. The number of revolutions of the positive-thread drive screw 403 that the cleaning brush 404 must rotate to the bottom is equivalent to the number of revolutions of the reverse-thread screw 407 that the first lifting block 410 must rotate to the top. The design of the reverse-thread screw 407 and the positive-thread drive screw 403 ensures that when the cleaning brush 404 reaches the bottom, the first lifting block 410 reaches the top (or vice versa).

[0058] When the automatic cleaning water flow control mechanism 4 is working, the servo motor 401 is started, and its output end drives the first gear 402 to rotate. On the one hand, the first gear 402 drives the cleaning brush 404 to move up and down along the limit guide rod 405 through the positive wire driving screw 403 to clean the protective net 105; on the other hand, through engagement with the second gear 406, the power is transmitted to the reverse wire screw 407, thereby driving the first lifting block 410 and the second lifting block 413 to move along the reverse wire screw 407 and the positive wire screw 409 respectively, thereby controlling the first water flow regulating valve plate 411 and the second water flow regulating valve plate 414 to move up and down along the limit guide slot 103 through the first limit guide slider 412 and the second limit guide slider 415, thereby adjusting the size of the water flow channel, thereby controlling the water flow, and realizing the simultaneous cleaning and water flow control.

[0059] The device automatically cleans the protective net, effectively removing debris clogged on it and preventing large particles from clogging the ecological filter element. Furthermore, by adjusting the opening and closing of the water flow regulating valve plate, the water flow rate can be flexibly controlled to meet purification requirements under different flow conditions, ensuring the stability and reliability of the purification effect and achieving continuous and effective purification of river water quality.

[0062] S100: Install the ecological filter element device in the river channel, ensuring that the ecological filter element unit is perpendicular to the direction of water flow; allowing the water flow to effectively pass through each filter layer, including the biochar filter layer, the microbial preparation sponge medium filter layer and the iron-carbon composite material filter layer, to achieve multiple purification effects such as physical adsorption, microbial degradation and electrochemical micro-electrolysis.

[0063] S200: Start the automatic cleaning water flow control mechanism, the servo motor receives the start signal and starts to run, its output end drives the first gear to rotate, the first gear not only drives the positive wire drive screw to rotate, but also transmits power to the second gear through meshing, preparing for the subsequent water flow adjusting mechanism;

[0064] S300: The positive wire drive screw rotates to move the cleaning brush up and down along the limiting guide rod, automatically cleaning the protective net, and the garbage cleaned falls into the garbage collection net box, preventing secondary pollution and facilitating subsequent processing;

[0065] S400: During the cleaning process, the reverse wire screw and the positive wire screw adjust the opening and closing degree of the first water flow adjusting valve plate and the second water flow adjusting valve plate through the first lifting block and the second lifting block connected respectively, to control the water flow through the filter core unit, driven by the second gear;

[0066] S500: During the process, the movable net door is opened regularly to check the state of the ecological filter core unit, assess whether there is a blockage phenomenon, and monitor the microbial activity. According to the inspection, the biological carbon, microbial preparation or iron-carbon composite material is replaced or supplemented in time to maintain the best performance of the ecological filter core device and continuously and effectively purify the river water quality.
