[0002] River scenery is not only a common landscape form, but also an important ecological corridor and recreational resource, which has extremely high value in environmental protection and tourism development. However, with the acceleration of industrialization and urbanization, river water pollution is becoming more and more serious. Problems such as eutrophication, heavy metal pollution, and organic pollution are frequent, posing a serious threat to the ecological environment. Traditional river water treatment methods are often carried out through manual salvage of garbage, chemical treatment, physical filtration, etc., but these methods have many limitations. Manual salvage is inefficient and costly, chemical treatment may cause secondary pollution, and physical filtration is prone to clogging and requires frequent replacement of filter materials. In recent years, ecological purification technology has gradually become an important means of river water purification due to its advantages such as environmental protection and sustainability. For example, the patent document with application number CN202211545387.X provides an ecological river water purification system, including a spur dike, a slag and algae cleaning device and a water purification unit, characterized in that the spur dike is located on one side of the river channel, extending obliquely from the river bank into the river channel, a slag and algae cleaning device is provided next to the spur dike head, and an inlet pipe is provided between the spur dike and the slag and algae cleaning device. The water purification unit is located on the river bank next to the spur dike. The water purification unit is provided with a sand filter tank, a biochemical tank, a membrane filter device, a clear water tank and a nutrient salt addition system in sequence according to the water flow direction. The river water body is connected to the sand filter tank through an inlet pipe, the sand filter tank is connected to the biochemical tank through a pipe, the biochemical tank is connected to the membrane filter device through a pipe, one end of the water outlet of the membrane filter device is connected to the clear water tank through a pipe, and the other end is connected to the river channel through a drainage pipe. This invention can intercept surface source pollution, reduce the concentration of pollutants in rivers, and improve the purification capacity of rivers. However, the system structure of this invention is complex, which is not conducive to subsequent maintenance and cannot achieve the problem of long-term water purification. Summary of the invention

[0003] In view of the above defects or improvement needs of the prior art, the present invention provides a multi-component long-term ecological filter element device and a method of use for purifying river water quality. The ecological filter element effectively removes pollutants such as suspended matter, organic matter, and heavy metal ions in the water, and the automatic cleaning water flow control mechanism is equipped with a servo motor as a power source to automatically remove large particles of impurities on the ecological filter element. At the same time, the water flow through the ecological filter element is flexibly adjusted, and the components work together, which not only improves the purification efficiency and water purification effect of the river water quality, but also prolongs the service life of the filter element, ensures long-term stable purification performance, and reduces operation and maintenance costs.

[0042] like Figure 1As shown, the embodiment of the present invention provides a multi-component long-term ecological filter device for purifying river water quality, including an ecological filter component 1, a first mounting cover 2, a second mounting cover 3, an automatic cleaning water flow control mechanism 4, and a garbage collection net box 5. The first mounting cover 2 is fixedly installed at the top front end of the ecological filter component 1, and the second mounting cover 3 is fixedly installed in the middle of the top of the first mounting cover 2. The automatic cleaning water flow control mechanism 4 is arranged on the front of the ecological filter component 1, and the garbage collection net box 5 is fixedly installed at the bottom. The ecological filter component 1 includes an ecological filter unit 102 with multiple layers of filter media arranged inside. The ecological filter unit 102 effectively removes suspended matter, organic matter, heavy metal ions and other pollutants in the water. The ecological filter unit 102 is continuously cleaned by the automatic cleaning water flow control mechanism 4, which prolongs the service life of the filter. The garbage collection net box 5 can collect the garbage cleaned from the ecological filter unit 102 by the automatic cleaning water flow control mechanism 4, which is convenient for cleaning and can avoid the cleaned garbage from secondary pollution of the river, further improving the effect of river purification and management. Through the coordinated work of various components, the overall purification efficiency and water purification effect are improved.

[0043] Specifically, Figure 2-3 As shown, the ecological filtration assembly includes a mounting shell 101, an ecological filter element unit 102, a limiting guide slide 103, a movable net door 104 and a protective net 105.

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

[0045] The ecological filter element unit 102 is installed inside the installation shell 101 and is the core part of the ecological filtration component 1. It includes a biochar filter layer 1021, a microbial preparation sponge medium filter layer 1022 and an iron-carbon composite material filter layer 1023 fixedly installed from front to back. The biochar filter layer 1021 can enhance the adsorption performance of the overall filter element and provide a habitat for microorganisms. The microbial preparation sponge medium filter layer 1022 is used to fix the microbial preparation. The iron-carbon composite material filter layer 1023 is used to achieve electrochemical micro-electrolysis. The physical, chemical and biological triple purification mechanism is realized through multiple layers of filter media to enhance the purification effect.

[0046] The protection net 105 is fixedly installed on the front side of the installation shell 101 , and can effectively intercept large particles of impurities and garbage, thereby preventing the large particles of impurities and garbage from clogging the ecological filter element unit 102 .

[0047] The movable mesh door 104 is hingedly connected to the back of the mounting shell 101, so that the blockage and microbial activity of the ecological filter element unit 102 can be checked regularly after opening, and the microbial preparation can be replaced or supplemented when necessary to ensure the normal operation of all components of the entire ecological filter element device and to continuously and effectively purify the river water quality.

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

[0049] like Figure 4-5 As shown, the automatic cleaning water flow control mechanism 4 is used for automatically cleaning and adjusting the water flow, and includes a servo motor 401, a first gear 402, a positive wire driving screw 403, a cleaning brush 404, a limit guide rod 405, a second gear 406, a negative wire screw 407, a connecting rod 408, a positive wire screw 409, a first lifting block 410, a first water flow regulating valve plate 411, a first water flow regulating valve plate 412, a second lifting block 413, a second water flow regulating valve plate 414, and a first limit guide slider 33.

[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 top of the inner wall of the second mounting cover 3. After the bottom output end moves through the bottom of the second mounting cover 3 and the top of the inner wall of the first mounting cover 2 in sequence, 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 thread driving screw 403 is fixedly mounted on the bottom, and the front end of the outer wall is movably engaged with the second gear 406, which is used to transmit the rotational power of the servo motor 401 to the positive thread driving screw 403, and is engaged with the second gear 406 to achieve power distribution;

[0052] The bottom of the positive-wire driving screw rod 403 is movably connected to the outer wall mounting shell 101 of the ecological filtering component 1, and the outer wall of the positive-wire driving screw rod 403 is threadedly connected to the cleaning brush 404. The back side of the cleaning brush 404 is movably connected to the front side of the protective net 105 of the ecological filter element unit 102. When the positive-wire driving screw rod 403 rotates, it drives the cleaning brush 404 to move up and down along its axial direction 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 to the bottom of the first mounting cover 2, and the bottom is fixedly connected to the outer wall of the ecological filtering component 1, providing a stable guide for the cleaning brush 404 to limit its movement path and prevent the cleaning brush 404 from deviating from the track during movement.

[0054] The second gear 406 is movably engaged with the front end of the outer wall of the first gear 402, and its top is movably connected to the top of the inner wall of the first mounting cover 2, and its bottom movably passes through the bottom of the first mounting cover 2, and is fixedly installed with the anti-screw rod 407. The second gear 406 is used to receive the power transmitted by the first gear 402 and drive the anti-screw rod 407 to rotate. The bottom of the anti-screw rod 407 is fixedly installed with the connecting rod 408, and the bottom of the connecting rod 408 is fixedly installed with the positive screw rod 409, and the pitch of the positive screw rod 409 is consistent with that of the anti-screw rod 407, but the rotation direction is opposite.

[0055] The reverse screw rod 407 is threadedly connected to the first lifting block 410, and the first water flow regulating valve plate 411 is fixedly installed on the front of the first lifting block 410. The second lifting block 413 is threadedly connected to the outer wall of the positive screw rod 409, and the second water flow regulating valve plate 414 is fixedly installed on the front of the second lifting block 413. By rotating the reverse screw rod 407 and the positive screw rod 409, the first lifting block 410 and the second lifting block 413 can move toward or away from each other up and down on the screw rod, and the first water flow regulating valve plate 411 and the second water flow regulating valve plate 414 move with the movement of the lifting blocks, and cooperate to adjust the size of the water flow channel to achieve the purpose of regulating the water flow.

[0056] The first limiting guide slider 412 is fixedly installed on the back of the first water flow regulating valve plate 411, and the outer wall of the first limiting guide slider 412 is slidably connected to the limiting guide groove 103 on the inner wall of the mounting shell 101; the second limiting guide slider 415 is fixedly installed on the back of the second water flow regulating valve plate 414, and the outer wall of the second limiting guide slider 415 is slidably connected to the limiting guide groove 103 on the inner wall of the mounting shell 101, and the guide groove provides stable guidance for the limiting guide slider to ensure movement along a predetermined track, and the limiting guide slider moves in the guide groove to drive the water flow regulating valve plate to open or close the water flow channel and adjust the water flow size.

[0057] The pitch of the anti-thread screw rod 407 is smaller than that of the positive thread driving screw rod 403. The number of turns of the positive thread driving screw rod 403 driving the cleaning brush 404 to move to the bottom is equal to the number of turns of the anti-thread screw rod 407 driving the first lifting block 410 to move to the top. The design of the anti-thread screw rod 407 and the positive thread driving screw rod 403 is such that when the cleaning brush 404 moves to the bottom, the first lifting block 410 just moves to 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 thread driving screw rod 403 to clean the protective net 105; on the other hand, through the meshing with the second gear 406, the power is transmitted to the reverse thread screw rod 407, and then the first lifting block 410 and the second lifting block 413 are driven to move along the reverse thread screw rod 407 and the positive thread screw rod 409 respectively, and then the first water flow regulating valve plate 411 and the second water flow regulating valve plate 414 are controlled to move up and down along the limit guide slide groove 103 through the first limit guide slider 412 and the second limit guide slider 415, so as to adjust the size of the water flow channel, thereby controlling the water flow, and realizing the simultaneous cleaning and water flow control.

[0059] The device of the present invention can automatically clean the protection net, effectively remove the impurities and garbage blocking the protection net, and avoid the blockage of the ecological filter element unit by large particles of impurities and garbage. At the same time, by adjusting the opening and closing degree of the water flow regulating valve plate, the flow rate of the water flow can be flexibly controlled to adapt to the purification needs under different flow conditions, ensuring the stability and reliability of the purification effect, and realizing the continuous and effective purification of the river water quality.

[0060] Example 2

[0061] like Figure 6 As shown, based on a multi-component long-term ecological filter device for purifying river water quality in the above embodiment, this embodiment provides a flow chart of a method for using a multi-component long-term ecological filter device for purifying river water quality, and the method includes the following specific steps:

[0062] S100: Install the ecological filter device in the river channel and ensure that the ecological filter unit is perpendicular to the water flow direction; so that the water flow can 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 starts to operate after receiving the start signal. Its output end drives the first gear to rotate. The first gear not only drives the positive wire to drive the lead screw to rotate, but also transmits power to the second gear through meshing, so as to prepare for the subsequent water flow adjustment mechanism.

[0064] S300: The positive wire drives the screw rod to rotate, causing the cleaning brush to move up and down along the limit guide rod to automatically clean the protection net. The cleaned garbage falls into the garbage collection box to prevent secondary pollution and facilitate subsequent treatment;

[0065] S400: During the cleaning process, the reverse screw rod and the forward screw rod are driven by the second gear to adjust the opening and closing degree of the first water flow regulating valve plate and the second water flow regulating valve plate through the first lifting block and the second lifting block connected to them respectively, so as to control the water flow passing through the filter element unit;

[0066] S500: During the process, open the movable mesh door regularly to check the status of the ecological filter unit, evaluate whether there is any blockage, and monitor the activity of microorganisms. According to the inspection results, replace or supplement the biochar, microbial preparations or iron-carbon composite materials in time to maintain the optimal performance of the ecological filter device and continuously and effectively purify the river water quality.

[0067] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
