Description

Technical Field

[0001] This invention relates to the field of water environment management technology, and more specifically, to a water environment ecological restoration device. Background Technology

[0002] With the continuous expansion of industrial production and the accelerating pace of urbanization, large amounts of industrial wastewater and domestic sewage are discharged into natural water bodies such as rivers and lakes without effective treatment. This not only exacerbates eutrophication and drastically deteriorates water quality, but also severely damages the original ecological structure and balance of water bodies, threatening the survival of aquatic organisms and restricting the self-repair capacity of aquatic ecosystems. However, existing water environment restoration devices generally suffer from limitations such as single-function operation and insufficient restoration coverage, and are highly dependent on manual labor—requiring a large number of people to manually remove garbage and suspended pollutants from water bodies. This process not only incurs high labor costs but also consumes a significant amount of time, resulting in poor coordination of the overall restoration process, significantly reducing the overall efficiency of water body restoration, and greatly increasing the comprehensive operation and maintenance costs of water environment management, making it difficult to meet the needs of large-scale and efficient governance. Summary of the Invention

The locking plug is used to pass through the movable block and be inserted into the locking hole.

[0010] Optionally, the purification box is provided with a limiting baffle, which is used to abut against the end face of the activated carbon plate facing the drain outlet of the purification box.

[0011] Optionally, the quantitative drug feeding mechanism includes a discharge pipe, a rotating disk, a material cylinder, a contamination prevention cylinder, and a second motor.

[0013] The beneficial effects of the water environment ecological restoration device of this invention are as follows: The sedimentation filter box adopts an open-top structure and is equipped with height-adjustable filter plates. After the water source flows in through the inlet pipe, the filter plates can be flexibly adjusted in installation position according to the impurity content and water level, ensuring adaptability to impurity filtration in water bodies with different levels of pollution. The filter plates are height-adjustable, and after filtration, they can be quickly adjusted to a position that is easy to clean. Workers can directly clean the suspended impurities and garbage trapped on the filter plates without repeatedly scooping them out of the water. This design significantly reduces the intensity of manual labor, reduces manpower input, avoids interference of the scooping process with the restoration process, effectively shortens the impurity cleaning time, and improves the efficiency of the initial filtration stage. The activated carbon plate installed in the purification box can perform deep purification treatment on the water after sedimentation and filtration, adsorbing residual harmful substances, odors, and micro-pollutants in the water, further improving the water purity. At the same time, the water purified by the activated carbon plate provides a better treatment foundation for subsequent restoration stages, avoiding the impact of incompletely purified pollutants on the restoration effect, and ensuring the continuity and reliability of the restoration process. The quantitative dosing mechanism of the remediation tank enables automated quantitative addition of remediation materials. It can precisely control the amount of reagent used in each batch of water to be treated through preset parameters, avoiding the problems of overdosing, underdosing, or uneven dosing that are prone to occur when doing manual dosing. This ensures that the water quality remediation effect is uniform and stable, avoids incomplete remediation or reagent residue pollution caused by improper reagent dosage, and saves reagent costs. The matching stirring mechanism can quickly and thoroughly mix the water and remediation materials, accelerate the reaction rate between the reagent and pollutants, shorten the remediation cycle, and ensure that the water quality of the remediated water meets the standards.

[0014] This invention connects the sedimentation filter box, purification box, and remediation tank sequentially via pipelines, forming a continuous automated processing flow of preliminary filtration, deep purification, and precise remediation. This eliminates the need for manual intervention in each stage, preventing interruptions in the remediation process caused by human error and ensuring continuous and stable operation. The entire device covers the core aspects of water remediation, offering comprehensive functionality and strong synergy, overcoming the shortcomings of existing devices in terms of insufficient remediation coverage. Furthermore, structural optimization in each stage reduces reliance on manual labor, lowering both labor and time costs, significantly improving the overall efficiency of water remediation. This meets the needs of large-scale, high-efficiency water environment management, providing a reliable guarantee for the rapid recovery of damaged aquatic ecosystems. Attached Figure Description

[0020] like Figures 1 to 10As shown in the figure, an embodiment of the present invention provides a water environment ecological restoration device, characterized in that it includes: a sedimentation filter box 1, a purification box 2 and a restoration tank 3, wherein the drain outlet of the sedimentation filter box 1 is connected to the water inlet of the purification box 2, and the drain outlet of the purification box 2 is connected to the water inlet of the restoration tank 3. The sedimentation filter box 1 is a box structure with an open top. A filter plate 11 is installed inside the sedimentation filter box 1, and the height of the filter plate 11 inside the sedimentation filter box 1 is adjustable. A water inlet pipe 12 is installed on the sedimentation filter box 1, and the water inlet pipe 12 is used to supply water to flow into the sedimentation filter box 1.

[0021] Specifically, such as Figure 1 , Figures 2 to 4 As shown, the sedimentation filter box 1 is a box-shaped structure with an open top. A filter plate 11 for filtering impurities in the water is installed at the bottom. The height of the filter plate 11 can be flexibly adjusted within the sedimentation filter box 1 to adapt to different water levels and impurity filtration requirements. An inlet pipe 12 is installed on the sedimentation filter box 1, which is connected to an external water source delivery channel to stably introduce the water to be repaired into the sedimentation filter box 1. It should be noted that the inlet of the inlet pipe 12 is higher than the lowest point of the filter plate 11. The outlet of the sedimentation filter box 1 is directly connected to the inlet of the purification box 2, allowing the filtered water to flow smoothly into subsequent purification stages.

[0022] The purification box 2 is equipped with an activated carbon plate 21, and the water in the purification box 2 flows into the repair tank 3 from the drain outlet of the purification box 2 after passing through the activated carbon plate 21.

[0023] Specifically, such as Figure 1 , Figures 5 to 7 As shown, an activated carbon plate 21 is fixedly installed inside the purification box 2. The activated carbon plate 21 covers the water flow path inside the purification box 2, ensuring that the water entering the purification box 2 is completely purified by the adsorption of the activated carbon plate 21 before flowing out from the drain of the purification box 2. The water inlet of the purification box 2 is connected to the drain of the sedimentation filter box 1, and the drain is connected to the water inlet of the repair tank 3, forming a continuous water transport channel.

[0024] The repair tank 3 is equipped with a metering feeding mechanism 31, which is used to meterly supply repair materials into the repair tank 3. The repair tank 3 is also equipped with a stirring mechanism 32, which is used to stir and mix the water and the repair materials in the repair tank 3, and the mixed water is discharged through the drain outlet of the repair tank 3.

[0025] Specifically, such as Figure 1 , Figure 8 and Figure 9As shown, the repair tank 3 is equipped with a quantitative drug feeding mechanism 31, which can accurately control the amount of repair material added and stably supply the repair material into the repair tank 3 according to the preset dosage; the repair tank 3 is also equipped with a stirring mechanism 32, the stirring component of the stirring mechanism 32 extends into the water inside the repair tank 3, and is used to fully mix the water and the repair material; the water inlet of the repair tank 3 is connected to the drain outlet of the purification box 2, and a drain outlet is provided at the bottom or side to discharge the uniformly mixed repair water.

[0026] The sedimentation filter box 1 of this invention adopts an open-top structure and is equipped with a height-adjustable filter plate 11. After the water source flows in through the inlet pipe 12, the filter plate 11 can be flexibly adjusted in installation position according to the impurity content and water level of the water, ensuring adaptability to impurity filtration for water bodies with different levels of pollution. The filter plate 11 is height-adjustable, and after filtration, it can be quickly adjusted to a position that is easy to clean. Workers can directly clean the suspended impurities and garbage trapped on the filter plate 11 without repeatedly scooping them out of the water. This design significantly reduces the intensity of manual labor, reduces manpower input, avoids interference of the scooping process with the remediation process, effectively shortens the impurity cleaning time, and improves the efficiency of the initial filtration stage. The activated carbon plate 21 installed in the purification box 2 can perform deep purification treatment on the water after sedimentation and filtration, adsorbing residual harmful substances, odors, and micro-pollutants in the water, further improving the water purity. At the same time, the water purified by the activated carbon plate 21 provides a better treatment foundation for subsequent remediation stages, avoiding the impact of incompletely purified pollutants on the remediation effect, and ensuring the continuity and reliability of the remediation process. The quantitative dosing mechanism 31 configured in the repair tank 3 realizes the automated quantitative addition of repair materials. It can accurately control the amount of reagent used in each batch of water to be treated through preset parameters, avoiding the problems of overdosing, underdosing, or uneven dosing that are easy to occur when doing manual dosing. This ensures that the water quality repair effect is uniform and stable, avoids incomplete repair or reagent residue pollution caused by improper reagent dosage, and saves reagent costs. The matching stirring mechanism 32 can quickly and thoroughly mix the water and repair materials, accelerate the reaction rate between the reagent and pollutants, shorten the repair cycle, and ensure that the water quality of the repaired water meets the standards.

[0027] In this embodiment of the invention, the sedimentation filter box 1, purification box 2, and restoration tank 3 are sequentially connected via pipelines, forming a continuous automated processing flow of preliminary filtration, deep purification, and precise restoration. This eliminates the need for manual intervention in the connection between each stage, avoiding interruptions in the restoration process caused by human intervention and ensuring continuous and stable operation of the device. The entire device covers the core aspects of water body restoration, offering comprehensive functionality and strong synergy, overcoming the shortcomings of existing devices in terms of insufficient restoration coverage. Simultaneously, each stage has undergone structural optimization to reduce reliance on manual labor, thereby reducing labor and time costs and significantly improving the overall efficiency of water body restoration. This meets the needs of large-scale, high-efficiency water environment management and provides a reliable guarantee for the rapid recovery of damaged aquatic ecosystems.

[0028] Optionally, a portal frame 13 is provided on the upper part of the sedimentation filter box 1. A first motor 14 is provided on the portal frame 13. A drive wheel 15 is provided at the output end of the first motor 14. A driven wheel 16 is rotatably connected to the portal frame 13. The drive wheel 15 and the driven wheel 16 are connected in a transmission connection. A threaded hole is provided at the midpoint of the driven wheel 16. A first screw 17 is threadedly connected to the threaded hole in the vertical direction. The first screw 17 passes through the portal frame 13 and is connected to the filter plate 11 to drive the filter plate 11 to move in the vertical direction.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, the portal frame 13 has a "gate" shape and is fixedly installed on the upper edge of the sedimentation filter box 1. Its crossbeam spans the opening of the sedimentation filter box 1, providing stable mounting support for components such as the first motor 14 and the driven wheel 16. The crossbeam has a through hole for the first screw 17 to pass through, ensuring that the first screw 17 can move smoothly in the vertical direction. The first motor 14 is fixedly installed on one side of the crossbeam of the portal frame 13. Its output end is set in the horizontal direction and fixedly connected to the driving wheel 15. The driving wheel 15 rotates synchronously with the rotation of the output end of the first motor 14, serving as the starting component for power transmission. Driven wheel 16 is rotatably connected to the other side of the crossbeam of portal frame 13 via bearings, and is at the same horizontal height as driving wheel 15. Driving wheel 15 and driven wheel 16 are connected by a transmission belt or chain, allowing driven wheel 16 to rotate synchronously under the drive of driving wheel 15. A through threaded hole is provided at the midpoint of driven wheel 16 in the vertical direction, which is used to mate with first screw 17. First screw 17 is a long strip structure with threads on its outer surface, and its threads match the threaded hole at the midpoint of driven wheel 16. First screw 17 passes vertically through the through hole of portal frame 13 crossbeam and the threaded hole of driven wheel 16, and its lower end is fixedly connected to the top middle position of filter plate 11. It can rise and fall vertically according to the threaded engagement, thereby adjusting the height of filter plate 11.

[0030] When it is necessary to adjust the height of the filter plate 11 in the sedimentation filter box 1, the first motor 14 is started. The output end of the first motor 14 drives the drive wheel 15 to rotate. The drive wheel 15 drives the driven wheel 16 to rotate synchronously through the transmission belt or chain. Since the driven wheel 16 is threadedly connected to the first screw 17, and the first screw 17 is limited by the filter plate 11 and cannot rotate synchronously with the driven wheel 16, the rotation of the driven wheel 16 is converted into the linear motion of the first screw 17 in the vertical direction. If the first motor 14 rotates in the forward direction, the first screw 17 drives the filter plate 11 to move upward; if the first motor 14 rotates in the reverse direction, the first screw 17 drives the filter plate 11 to move downward. After the filter plate 11 is adjusted to the preset height, the first motor 14 is turned off to complete the height adjustment.

[0031] In this embodiment, the first motor 14 provides power, and through the transmission of the driving wheel 15 and the driven wheel 16 and the threaded engagement of the first screw 17, the height of the filter plate 11 is automatically adjusted without manual operation, greatly reducing the intensity of manual labor. Moreover, the height adjustment process is precise and controllable, and the position of the filter plate 11 can be flexibly adjusted according to the changes in water level and the thickness of impurity accumulation in the sedimentation filter box 1. This ensures that the filter plate 11 effectively intercepts impurities in the water, and avoids the problem of decreased filtration efficiency or impurity blockage caused by improper position of the filter plate 11. This further improves the filtration stability and adaptability of the sedimentation filter box 1, and ensures the smooth operation of subsequent purification and repair processes.

[0032] Optionally, the filter plate 11 is connected to the first screw 17 via a bracket 18. The bracket 18 has guide grooves 181 on both sides. The inner sidewalls of the gantry frame 13 and the sedimentation filter box 1 are provided with guide slides 19. The guide grooves 181 and the guide slides 19 are slidably engaged.

[0033] Specifically, such as Figures 2 to 4 As shown, the bracket 18 has a frame structure. Its bottom is fixedly connected to the end face of the filter plate 11 facing the sedimentation chamber 1 opening, and its top is fixedly connected to the lower end of the first screw 17, which serves as a bridge connecting the filter plate 11 and the first screw 17, ensuring that the lifting force of the first screw 17 can be stably transmitted to the filter plate 11. Guide grooves 181 are provided on both sides of the bracket 18 along the vertical direction. The groove openings of the guide grooves 181 face outwards, and the groove size is adapted to the guide slide 19 for forming a sliding fit with the guide slide 19. The guide slide 19 is a long strip-shaped protrusion extending in the vertical direction. It is divided into two parts. One part is fixedly installed in the corresponding position on the inner side wall of the gantry frame 13, and the other part is fixedly installed in the corresponding position on the inner side wall of the sedimentation filter box 1. The two parts of the guide slide 19 are aligned in the vertical direction to form a continuous guide path. The cross-sectional shape of the guide slide 19 matches the guide groove 181 of the bracket 18, and can be embedded in the guide groove 181, allowing the bracket 18 to slide along its length.

[0034] When the first screw 17 is driven by the first motor 14 to adjust the height of the filter plate 11, the first screw 17 drives the bracket 18 to move synchronously. The guide grooves 181 on both sides of the bracket 18 slide vertically along the guide slides 19 on the inner sidewall of the portal frame 13 and the sedimentation filter box 1. If the first screw 17 drives the bracket 18 to move upward, the guide grooves 181 slide upward along the guide slides 19, and the bracket 18 drives the filter plate 11 to rise steadily. If the first screw 17 drives the bracket 18 to move downward, the guide grooves 181 slide downward along the guide slides 19, and the bracket 18 drives the filter plate 11 to fall steadily. Throughout the process, the guide grooves 181 and the guide slides 19 always maintain a sliding fit, limiting the horizontal displacement of the bracket 18 and ensuring that the filter plate 11 moves only in the vertical direction until the filter plate 11 reaches the preset height.

[0035] In this embodiment, the support 18 achieves a stable connection between the filter plate 11 and the first screw 17, avoiding the uneven force that may be caused by the first screw 17 directly connecting to the filter plate 11, and ensuring the structural stability of the filter plate 11 during the lifting and lowering process. At the same time, the sliding cooperation between the guide groove 181 and the guide slide 19 can effectively limit the horizontal deviation of the support 18 and the filter plate 11, preventing the filter plate 11 from tilting or jamming due to the thread transmission deviation of the first screw 17 or the impact of water during the lifting and lowering process, ensuring that the filter plate 11 always lifts and lowers smoothly in the vertical direction. This not only improves the accuracy of the height adjustment of the filter plate 11, but also avoids the filtration gap or structural damage caused by the tilting of the filter plate 11, further ensuring the stable and reliable filtration function of the sedimentation filter box 1.

[0036] Optionally, the portal frame 13 is provided with a guide sliding hole 131, and the bracket 18 is provided with a guide sliding rod 182 along the vertical direction, the guide sliding rod 182 passing through the guide sliding hole 131.

[0037] Specifically, such as Figures 2 to 4 As shown, the guide sliding holes 131 are circular through holes opened on the crossbeam of the portal frame 13, with at least two holes, and are symmetrically distributed around the through holes of the first screw 17 passing through the portal frame 13. The diameter of the guide sliding holes 131 is adapted to the diameter of the guide sliding rod 182, and the inner wall is smooth to ensure that the guide sliding rod 182 can slide smoothly along its axial direction, providing a vertical movement channel for the guide sliding rod 182. The guide sliding rod 182 is a cylindrical strip structure, with the same number as the guide sliding holes 131, and is fixedly connected to the top of the bracket 18 in the vertical direction, and its position corresponds one-to-one with the guide sliding holes 131 on the portal frame 13. The length of the guide sliding rod 182 is greater than the maximum adjustment stroke of the filter plate 11. The lower end is fixed to the top of the bracket 18, and the upper end passes through the corresponding guide sliding hole 131 and can slide vertically along the guide sliding hole 131, forming a double guide structure with the guide sliding hole 131.

[0038] When the first screw 17 driven by the first motor 14 moves the bracket 18 and filter plate 11 up and down, the guide slide rod 182 at the top of the bracket 18 moves synchronously with the bracket 18. If the first screw 17 moves the bracket 18 upward, the guide slide rod 182 slides upward along the guide slide hole 131 on the portal frame 13, and the length of its upper end extending out of the guide slide hole 131 increases. If the first screw 17 moves the bracket 18 downward, the guide slide rod 182 slides downward along the guide slide hole 131, and the length of its upper end extending out of the guide slide hole 131 decreases. During the entire lifting process, the guide slide rod 182 always slides vertically within the guide slide hole 131, and together with the guide grooves 181 on both sides of the bracket 18, the sedimentation filter box 1, and the guide slide strips 19 of the portal frame 13, it restricts the non-vertical displacement of the bracket 18 until the filter plate 11 is adjusted to the preset height. After the first motor 14 is turned off, the cooperation state between the guide slide rod 182 and the guide slide hole 131 remains stable, maintaining the height position of the filter plate 11.

[0039] In this embodiment, the guide sliding hole 131 of the portal frame 13 and the guide sliding rod 182 of the bracket 18 form a vertical sliding fit. Together with the guide grooves 181 and guide sliding strips 19 on both sides of the bracket, they form a double guiding constraint, which further restricts the horizontal offset and rotation of the bracket 18 and the filter plate 11. This prevents the filter plate 11 from tilting, jamming, or twisting during the lifting process due to water impact, thread transmission clearance, or other factors, ensuring that the filter plate 11 always moves smoothly in the vertical direction and improving the accuracy of height adjustment. At the same time, the cooperation between the guide sliding rod 182 and the guide sliding hole 131 can share the radial force borne by the first screw 17, reducing thread wear or bending deformation of the first screw 17 caused by unilateral force, extending the service life of the components, and further ensuring the long-term stable operation of the sedimentation filter box 1.

[0040] Optionally, the top of the purification box 2 is provided with an assembly slot 22 that communicates with the interior of the purification box 2. The assembly slot 22 is used for the activated carbon plate 21 to be inserted into the purification box 2. The top of the activated carbon plate 21 is provided with a cover plate 23. The end face of the cover plate 23 facing away from the activated carbon plate 21 is provided with a handle 24. The cover plate 23 is used to cover the top opening of the assembly slot 22 when the activated carbon plate 21 is inserted into the purification box 2.

[0041] Specifically, such as Figure 6 and Figure 7As shown, the assembly groove 22 is a rectangular groove located at the top of the purification box 2. The groove penetrates the top wall of the purification box 2 and communicates with the interior of the purification box 2. The length and width of the groove are adapted to the external dimensions of the activated carbon plate 21, ensuring that the activated carbon plate 21 can be smoothly installed into the purification box 2 along the assembly groove 22. The depth of the assembly groove 22 matches the internal height of the purification box 2, so that the activated carbon plate 21 can completely cover the water flow path inside the purification box 2 after being installed, ensuring the purification effect. The cover plate 23 is a flat plate structure that matches the opening size of the top of the assembly groove 22. The material is the same as that of the purification box 2. Its bottom is fixedly connected to the top of the activated carbon plate 21. When the activated carbon plate 21 is installed into the purification box 2 through the assembly groove 22, the cover plate 23 just covers the top of the assembly groove 22, which can seal the gap between the assembly groove 22 and the outside, preventing impurities from falling into the purification box 2. At the same time, it limits the activated carbon plate 21 and prevents it from shifting under the impact of water. The handle 24 is a U-shaped or columnar protrusion structure, which is fixedly installed on the end face of the cover plate 23 away from the activated carbon plate 21, i.e., the top surface of the cover plate 23. It is centrally or symmetrically distributed, and the material has sufficient strength to bear the weight of the activated carbon plate 21, so that the operator can hold it and apply force to realize the insertion and removal of the activated carbon plate 21.

[0042] When it is necessary to install the activated carbon plate 21, the operator holds the handle 24 and aligns the activated carbon plate 21 with the assembly slot 22 on the top of the purification box 2. The plate is then vertically lowered into the purification box 2 until it is fully inserted and fits the pre-set support structure inside. At this point, the cover plate 23 covers the top of the assembly slot 22, completing the installation of the activated carbon plate 21. When it is necessary to replace or maintain the activated carbon plate 21, the operator holds the handle 24 again and applies upward pulling force to move the cover plate 23 and the activated carbon plate 21 vertically upward along the assembly slot 22 until the activated carbon plate 21 is completely detached from the purification box 2. Subsequent replacement or cleaning operations can then be performed. After replacement, the installation steps can be repeated.

[0043] In this embodiment, the assembly slot 22 provides a precise installation channel for the activated carbon plate 21, ensuring that the activated carbon plate 21 is installed in the correct position and guaranteeing effective purification of the water. The cover plate 23 can seal the assembly slot 22 to prevent external impurities from entering the purification box 2 and contaminating the water, while fixing the position of the activated carbon plate 21. The handle 24 provides a convenient point of force for the operator, so that the installation and removal of the activated carbon plate 21 can be done without complicated tools, greatly simplifying the replacement and maintenance process, reducing manual operation time and labor intensity, avoiding interruption of the purification process due to the inconvenience of replacing the activated carbon plate 21, and further improving the ease of use and purification continuity of the purification box 2.

[0044] Optionally, two fixed blocks 25 are symmetrically arranged on the top of the purification box 2. A second screw 26 is rotatably connected between the two fixed blocks 25. Two moving blocks 27 are threadedly connected to the second screw 26. By rotating the second screw 26, the two moving blocks 27 are driven to move towards or away from each other. Each moving block 27 is provided with a corresponding locking plug 271. The side wall of the cover plate 23 is provided with a protrusion 231. A locking hole 232 is opened on the protrusion 231. The locking plug 271 is used to pass through the moving block 27 and insert into the locking hole 232.

[0045] Specifically, such as Figures 5 to 7 As shown, the two fixed blocks 25 are block-shaped structures, symmetrically fixedly installed on the top of the purification box 2 and located on both sides of the assembly groove 22, providing rotational support for the second screw 26; the second screw 26 is a long strip structure with threads on its outer surface, and its two ends are rotatably connected to the opposite sides of the two fixed blocks 25 through bearings, and the threads of the second screw 26 are divided into two sections with opposite directions of rotation, such as the left section being a left-hand thread and the right section being a right-hand thread, to ensure that the two moving blocks 27 can move synchronously in opposite directions when rotated. Two movable blocks 27 are block-shaped structures, respectively fitted onto the two reverse threads of the second screw 26. A threaded hole matching the corresponding thread is opened at the midpoint of each movable block 27, connecting it to the second screw 26 via threaded engagement. A locking insert 271 is fixedly connected to the side of each movable block 27 facing the cover plate 23. The locking insert 271 is an elongated protrusion, its cross-sectional shape matching the locking insertion hole 232 on the protrusion 231 of the cover plate 23, allowing it to be inserted into the locking insertion hole 232 to form a lock. Two protrusions 231 are block-shaped structures, symmetrically fixed to the two side walls of the cover plate 23, their positions corresponding one-to-one with the locking inserts 271 on the two movable blocks 27. Each protrusion 231 has a locking insertion hole 232 on its side facing the locking insert 271. The locking insertion hole 232 is a blind hole or a through hole, its diameter matching the diameter of the locking insert 271, used for insertion of the locking insert 271 to fix the position of the cover plate 23.

[0046] When the activated carbon plate 21 is loaded into the purification box 2 through the assembly slot 22 and the cover plate 23 covers the top of the assembly slot 22, the second screw 26 is rotated. Since the two threads of the second screw 26 rotate in opposite directions, the two moving blocks 27 move along the second screw 26 toward each other under the action of the threaded engagement, driving their respective locking blocks 271 to move synchronously until the locking blocks 271 are fully inserted into the locking holes 232 on the protrusions 231 of the cover plate 23, thus locking the cover plate 23 and preventing the cover plate 23 and the activated carbon plate 21 from shifting. When it is necessary to remove the activated carbon plate 21, the second screw 26 is rotated in the opposite direction, and the two moving blocks 27 move toward each other, driving the locking blocks 271 to disengage from the locking holes 232, releasing the lock on the cover plate 23. Then the handle 24 can be held to remove the activated carbon plate 21.

[0047] In this embodiment, the rotation of the second screw 26 drives the two moving blocks 27 to move in opposite directions, achieving precise insertion and removal of the locking plug 271 and the locking hole 232. This allows for quick locking and unlocking of the cover 23, making the operation convenient and the locking secure. It effectively prevents the cover 23 from shifting or the activated carbon plate 21 from loosening due to water impact or device vibration during the operation of the purification box 2, ensuring that the activated carbon plate 21 always stably covers the water flow path and guarantees the purification effect. At the same time, compared with traditional bolt fixing methods, there is no need to repeatedly disassemble and assemble bolts, which greatly simplifies the process of replacing and maintaining the activated carbon plate 21, reduces operation time and labor intensity, and further improves the reliability and ease of maintenance of the purification box 2.

[0048] Optionally, the purification box 2 is provided with a limiting baffle 28 inside, which is used to abut against the end face of the activated carbon plate 21 facing the drain outlet of the purification box 2.

[0049] Specifically, such as Figure 6 As shown, the limiting baffle 28 is a sheet-like structure, fixedly installed inside the purification box 2, and located on the side near the drain outlet of the purification box 2; there are at least two limiting baffles 28, symmetrically distributed on both sides of the inner side wall of the purification box 2, or continuously arranged along the width direction of the purification box 2 to form a strip-shaped baffle; the top surface of the limiting baffle 28 is flush with or slightly lower than the bottom surface of the activated carbon plate 21, and its end face facing the activated carbon plate 21 is a flat plane. When the activated carbon plate 21 is installed in the purification box 2, this end face can tightly abut against the end face of the activated carbon plate 21 facing the drain outlet of the purification box 2, forming a limiting constraint on the activated carbon plate 21.

[0050] In this embodiment, the limiting baffle 28, by abutting against the end face of the activated carbon plate 21 facing the drain outlet, can effectively limit the displacement of the activated carbon plate 21 in the purification box 2 along the water flow direction towards the drain outlet. This prevents the activated carbon plate 21 from shifting or tilting due to water impact, ensuring that the activated carbon plate 21 always accurately covers the water flow path. This ensures that the water is completely purified by the activated carbon plate 21 before being discharged, improving the stability of the purification effect. At the same time, the limiting baffle 28 provides a clear positioning benchmark for the installation of the activated carbon plate 21. Operators do not need to repeatedly adjust the position of the activated carbon plate 21; they can confirm that it is installed in place by abutting against the limiting baffle 28. This simplifies the installation process, improves installation efficiency, and further ensures the reliable operation of the purification function of the purification box 2.

[0051] Optionally, the quantitative drug feeding mechanism 31 includes a discharge pipe 311, a rotating disk 312, a feed cylinder 313, a contamination prevention cylinder 314, and a second motor 315. The discharge pipe 311 is located at the upper part of the repair tank 3 and communicates with the repair tank 3. The rotating disk 312 is rotatably connected to the discharge pipe 311. The feed cylinder 313 is located at the top of the rotating disk 312. The feed cylinder 313 includes a cylinder body 3131, a discharge pipe 3132, and a fixed support plate 3133. The contamination prevention cylinder 314 is located inside the cylinder body 3131, protecting the cylinder body 313. The interior of 1 is divided into a first region and a second region. The bottom of the first region is connected to the feeding hole on the fixed support plate 3133 through the discharge pipe 3132. The second motor 315 is located in the second region, and the output end of the second motor 315 is connected to the rotating disk 312. The rotating disk 312 has a discharge hole 3121 for communicating with the discharge pipe 311 and the feeding hole. The second motor 315 is used to drive the rotating disk 312 to rotate so that the discharge hole 3121 is aligned with the discharge pipe 3132.

[0052] Specifically, such as Figure 10As shown, the material discharge pipe 311 is a vertically extending tubular structure, vertically positioned at the top of the repair tank 3. Its lower end connects to the interior of the repair tank 3, and its upper end is attached to the bottom of the rotating disk 312, forming a channel for the repair material to enter the repair tank 3, ensuring that the material can accurately fall into the repair tank 3 along the material discharge pipe 311. The rotating disk 312 is a circular flat plate structure, horizontally positioned at the top of the material discharge pipe 311 and rotatably connected to it. Its diameter is larger than that of the material discharge pipe 311. The rotating disk 312 has at least one material discharge hole 3121, which is a vertically extending circular hole with a diameter that matches the diameter of the discharge pipe 3132 of the material cylinder 313. When the rotating disk 312 rotates to a specific angle, the material discharge hole 3121 can form a connecting channel with the discharge pipe 3132 and the material discharge pipe 311. The material cylinder 313 is used to store repair materials and includes a cylinder body 3131, a discharge pipe 3132, and a fixed support plate 3133. The cylinder body 3131 is a cylindrical body with an open top and a hollow interior to accommodate the repair materials. The discharge pipe 3132 is a tubular structure, vertically connected to the bottom center of the cylinder body 3131 and communicating with the interior of the cylinder body 3131 to discharge the materials inside the cylinder. The fixed support plate 3133 is a circular flat plate structure, fixedly connected to the lower end of the discharge pipe 3132, and the bottom of the fixed support plate 3133 is in contact with the top of the rotating disk 312, providing stable support for the material cylinder 313. The anti-fouling cylinder 314 is a conical cylinder with closed top and bottom, fixedly set at the internal center of the cylinder body 3131, maintaining a certain gap with the inner wall of the cylinder body 3131 to not affect the flow of materials inside the cylinder body 3131. Its interior is hollow and has sealing performance, used to accommodate and protect the second motor 315, preventing repair materials from entering the motor and affecting its operation. The second motor 315 is fixedly installed inside the anti-fouling cylinder 314. Its output end penetrates vertically downward through the bottom of the anti-fouling cylinder 314 and the fixed support plate 3133, and is fixedly connected to the top center of the rotating disk 312. It can drive the rotating disk 312 to rotate around its own axis, providing power for the rotation of the rotating disk 312.

[0053] In use, the second motor 315 inside the anti-fouling cylinder 314 is started. The output end of the second motor 315 drives the rotating disk 312 to rotate around its own axis. When the material discharge hole 3121 on the rotating disk 312 rotates to align with the discharge pipe 3132 of the material cylinder 313, the repair material in the material cylinder 313 falls into the material discharge hole 3121 under the action of gravity, then enters the material discharge pipe 311 through the material discharge hole 3121, and finally falls into the repair tank 3 along the material discharge pipe 311. When the amount of repair material added reaches the preset amount, the second motor 315 drives the rotating disk 312 to continue rotating, causing the material discharge hole 3121 to disalign with the discharge pipe 3132. The solid part of the rotating disk 312 blocks the lower end of the discharge pipe 3132, stopping the material addition and completing one quantitative drug feeding operation. The amount of repair material added is controlled by the preset rotation angle and rotation time of the second motor 315.

[0054] In this embodiment, the quantitative feeding mechanism drives the rotating disk 312 to rotate via the second motor 315. The quantitative feeding of materials is achieved by aligning and misaligning the material drop hole 3121 and the discharge pipe 3132, eliminating the need for manual intervention and avoiding dosage deviations caused by manual dosing. This ensures that each batch of water to be treated can be matched with a precise amount of remediation material, guaranteeing a uniform and stable water quality remediation effect. The anti-fouling cylinder 314 effectively isolates the remediation material from the second motor 315, preventing material contamination of the motor and thus extending its service life. At the same time, the overall structure, through the precise cooperation of the material drop pipe 311 and the material drop hole 3121, ensures that there is no leakage or residue of materials, reducing material waste and preventing impurities from entering the remediation tank 3 and affecting water quality, further improving the reliability and stability of the remediation process in the remediation tank 3.

[0055] Optionally, the stirring mechanism 32 includes a third motor 321, a stirring shaft 322, and stirring rods 323. The stirring shaft 322 is rotatably disposed inside the repair tank 3, and a plurality of stirring rods 323 are spaced apart on the stirring shaft 322. The third motor 321 is installed outside the repair tank 3, and the output end of the third motor 321 is connected to the stirring shaft 322.

[0056] Specifically, such as Figure 9 As shown, the third motor 321 is a power output component, fixedly installed on the outside of the repair tank 3, usually on the top or side of the repair tank 3. Its output end is fixedly connected to the internal stirring shaft 322 through a coupling or directly through the wall of the repair tank 3, providing stable rotational power to drive the stirring shaft 322 to rotate at a preset speed. The stirring shaft 322 is a long cylindrical structure, rotatably connected to the inside of the repair tank 3 along the vertical or horizontal direction of the repair tank 3, adapted to the structure of the repair tank 3. Both ends are rotatably engaged with the inner wall or end wall of the repair tank 3 through bearings to ensure smooth and uninterrupted rotation. One end of the stirring shaft 322 is fixedly connected to the output end of the third motor 321 and can rotate synchronously with the drive of the third motor 321, providing a mounting carrier and rotational support for the stirring rod 323. The stirring rod 323 is a long rod structure, and there are multiple rods. They are distributed at intervals along the length of the stirring shaft 322, and each stirring rod 323 is fixedly connected perpendicular to the axis of the stirring shaft 322. They can be arranged symmetrically or staggered. The length of the stirring rod 323 is adapted to the internal diameter of the repair tank 3, ensuring that it can cover most of the water area inside the repair tank 3 when it rotates, without any obvious stirring dead corners.

[0057] When the repair material is fed into the repair tank 3 through the metering feeding mechanism 31, and the repair water has entered the repair tank 3, the external third motor 321 is started. The output end of the third motor 321 drives the stirring shaft 322 to rotate inside the repair tank 3. The stirring shaft 322 synchronously drives the multiple stirring rods 323 distributed at intervals on it to rotate. During the rotation, the stirring rods 323 come into contact with the water and the repair material, producing a shearing and mixing effect on the two, so that the repair material is evenly dispersed into the water. The mixing time is adapted to the mixing requirements of the repair material and the water according to the preset mixing time. After the mixing is completed, the third motor 321 is turned off, the stirring shaft 322 and the stirring rods 323 stop rotating, and the mixed water is discharged through the drain of the repair tank 3.

[0058] In this embodiment, a third motor 321 provides stable power, which drives multiple stirring rods 323 to rotate via a stirring shaft 322. This allows for rapid and thorough mixing of the water and remediation materials within the remediation tank 3, avoiding uneven mixing and inconsistent remediation effects caused by localized accumulation of remediation materials. This ensures that each portion of water reacts precisely with the remediation materials. The multiple spaced stirring rods 323 cover most of the area within the remediation tank 3, reducing dead zones and further improving mixing uniformity. Simultaneously, the stirring process requires no manual intervention and operates fully automatically. This avoids the labor intensity and low efficiency of manual stirring while ensuring stable and controllable parameters such as stirring speed and duration, guaranteeing the consistency of remediation effects for each batch of water and providing a reliable guarantee for the ecological restoration quality after subsequent water discharge.

[0059] Optionally, the drain outlet of the sedimentation filter box 1 is connected to the inlet of the purification box 2 through a water pumping pipe 4, and a water pump 5 is installed on the water pumping pipe 4.

[0060] Specifically, such as Figure 1 As shown, the water pump 4 is a tubular structure with openings at both ends. It is made of corrosion-resistant, high-strength pipe materials such as PVC or stainless steel. One end is fixedly connected to the drain outlet of the sedimentation filter box 1 and internally connected, while the other end is fixedly connected to the inlet of the purification box 2 and internally connected, forming a dedicated channel for water transport between the sedimentation filter box 1 and the purification box 2. This ensures that water can flow directionally along the water pump 4 without leakage or overflow. The water pump 5 is a power transmission component, fixedly installed on the water pump 4 and internally connected to it. The water pump 5 has a preset pumping flow rate and head, and can generate stable negative pressure or thrust to provide power for the water flow within the water pump 4, driving the filtered water in the sedimentation filter box 1 towards the purification box 2.

[0061] In this embodiment, the water pump 4 achieves precise and sealed connection between the sedimentation filter box 1 and the purification box 2, avoiding secondary pollution caused by water contact with the outside world during transportation and preventing water leakage and waste. The water pump 5 provides stable power for water transportation, which can effectively overcome the height difference or pipeline resistance between the sedimentation filter box 1 and the purification box 2, ensuring that the filtered water enters the purification box 2 quickly and smoothly, avoiding water accumulation in the sedimentation filter box 1 or water shortage in the purification box 2 due to low natural flow efficiency, ensuring the continuous connection of the "filtration-purification" process, and further improving the operating efficiency and stability of the entire water environment ecological restoration device.

[0062] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
