Description

Technical Field

[0001] This utility model belongs to the field of water filtration technology, and in particular to an ecological water filter pool for water ecological environment restoration. Background Technology

[0002] With the acceleration of urbanization and the increase in industrial activities, water pollution has become increasingly serious, posing a huge threat to the ecological environment and human health. Water remediation in aquatic ecological environment research requires initial water filtration and cleaning. Traditional water purification methods typically employ single-filter screens or simple multi-layer filtration systems, which, while improving water quality to some extent, suffer from the following major problems.

[0003] In traditional filtration systems, the impurities that are intercepted are often scattered in various parts, making it difficult to process them centrally. These intercepted impurities cannot smoothly slide down to the centralized processing location, so when they are impacted by the water flow again, they are not only easily pushed back into the water, but also easily clog the filter screen, reducing the efficiency of water quality restoration. Utility Model Content

[0004] The purpose of this utility model is to provide an ecological water filtration pond for aquatic ecological environment restoration, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ecological filtration pond for aquatic ecological environment restoration, comprising:

[0006] The water filter tank body is used for water quality restoration in aquatic ecological environment research, and an inlet is integrally connected to the upper part of one end of the water filter tank body;

[0007] Aquatic ecosystem restoration filtration components include a U-shaped frame plate that is submerged and installed in the internal cavity of the filter tank body, and multi-stage filtration components installed in the U-shaped frame plate;

[0008] The lifting mechanism is located above the filter tank body and the U-shaped frame plate. When the lifting mechanism drives the U-shaped frame plate to rise, it is used for cleaning impurities in the U-shaped frame plate and replacing multi-stage filter components.

[0009] An emergency fall protection mechanism is symmetrically arranged inside the water filter tank body and located on both sides of the U-shaped frame plate. When the U-shaped frame plate is raised, the emergency fall protection mechanism extends into the inner cavity of the water filter tank body to support the bottom of the U-shaped frame plate.

[0010] The water flowing in through the inlet impacts the multi-stage filtration components, and the impurities trapped by the multi-stage filtration components slide down into the impurity collection box inside the U-shaped frame plate.

[0011] In a preferred embodiment, the multi-stage filtration component sequentially includes a first filter screen, a second filter screen, and a third filter screen with gradually decreasing pore size, wherein the first filter screen is located adjacent to the inflow end of the water inlet.

[0012] In a preferred embodiment, the lower parts of the first filter screen, the second filter screen, and the third filter screen are all integrally connected with a sliding filter screen part, and there is an angle between the first filter screen, the second filter screen, and the third filter screen and their own sliding filter screen parts for impurities to slide off.

[0013] In a preferred embodiment, the inner cavity of the impurity collection frame is provided with an inclined collection filter screen, the inclined collection filter screen being inclined in the same direction as the sliding filter screen portion, and the pore size of the inclined collection filter screen being smaller than the pore size of the third filter screen.

[0014] In this preferred embodiment, both ends of the U-shaped frame plate are integrally connected to hanging ear plates that can be hung on the top edge of the filter tank body, and the inner walls on both sides of the filter tank body are fixed with support blocks to support the U-shaped frame plate.

[0015] In this preferred embodiment, the outer walls of both sides of the water filter tank body near the water inlet are fixed with inverted L-shaped columns, and the tops of the two L-shaped columns are integrally connected with extended ear plates.

[0016] In this preferred embodiment, the lifting mechanism includes a rotating shaft rotatably mounted between two extension ear plates, a winding drum fixedly sleeved around the rotating shaft, a wire rope wound around the winding drum, and a servo motor fixed to the outer wall of one of the extension ear plates.

[0017] The output shaft of the servo motor is fixedly connected to one end of the rotating shaft.

[0018] In this preferred embodiment, the top surfaces of both hanging ear plates are welded with inverted U-shaped hanging rods, and a supporting hanging rod is welded between the two U-shaped hanging rods. A hanging ring is fixed at the middle position of the top surface of the supporting hanging rod, and the free end of the steel wire rope is connected to the hanging ring.

[0019] In this preferred embodiment, both ends of the second and third filter screens are welded with L-shaped adjusting rods. Each L-shaped adjusting rod is hung on the top surface of the ear plate, allowing the second and third filter screens to adjust their distance from the first filter screen according to the water flow rate. This enables the L-shaped adjusting rods to slide rubbing against the top surface of the ear plate. Each ear plate has symmetrically welded stops on both sides of its top surface, and a positioning rod is welded between adjacent stops for the L-shaped adjusting rod to pass through. When adjusting the distance between the first, second, and third filter screens, the L-shaped adjusting rod simply slides along the straight guide of the positioning rod to adjust the distance. After adjustment, the L-shaped adjusting rod is fixedly connected to the ear plate by locking bolts. When the water flow from the inlet is rapid, the water flow is allowed to pass through each angle of the first, second, and third filter screens. This allows impurities to easily slide down from the top of the sliding filter screen. When the water flow from the inlet is slow, the distance between the first, second, and third filter screens needs to be shortened. The distance is adjusted by sliding the L-adjustment rod, so that the water flow passes through each angle of the first, second, and third filter screens, allowing impurities to easily slide down from the top of the sliding filter screen. Thus, regardless of whether the water flow is rapid or slow, the distance between the first, second, and third filter screens can be adjusted to ensure uniform filtration and effective sliding of impurities.

[0020] In this preferred embodiment, fixed sleeves are symmetrically fixed to both outer walls of the water filter body. The inner cavity of each fixed sleeve extends into the inner cavity of the water filter body. Each fixed sleeve has a detachable end cap connected to its end furthest from the water filter body via detachable bolts. The emergency fall protection mechanism includes a hydraulic push-pull rod fixedly installed on the inner wall of each detachable end cap and a fall protection support shaft fixedly installed on the free end of each hydraulic push-pull rod. The free end of the fall protection support shaft can extend into the inner cavity of the water filter body via the extension of the hydraulic push-pull rod, thereby supporting the raised U-shaped frame plate, causing the U-shaped frame plate to press down on the fall protection support shaft. A positioning stroke groove is longitudinally formed on the upper part of the inner wall of each L-column. A positioning stroke slider is bolted to the top surface of each hanging ear plate. The positioning stroke slider fits into the positioning stroke groove. When the U-shaped frame plate is raised and lowered, the positioning stroke slider slides in the positioning stroke groove for positioning the U-shaped frame plate during raising and lowering.

[0021] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0022] In this aquatic ecological restoration project, the ecological filter pond features a multi-stage filtration system within a U-shaped frame panel. This system removes impurities of varying sizes layer by layer, significantly improving water purification efficiency. This multi-layered design is more effective than a single filter in intercepting particles of all sizes.

[0023] The lifting mechanism, comprising a servo motor, shaft, winding drum, and wire rope, automatically raises the U-shaped frame plate along with its filter components above the water surface for easy cleaning or replacement. This significantly reduces the need for manual operation, improving maintenance efficiency and safety.

[0024] Impurities intercepted by the multi-stage filtration system can smoothly slide into the impurity collection box for convenient centralized processing. This design reduces the risk of impurity clogging and simplifies the cleaning process. Attached Figure Description

[0039] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0040] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0041] This embodiment provides, for example Figures 1 to 8 An ecological water filter pool for aquatic ecological environment restoration is shown, comprising: a water filter pool body 1, an aquatic ecological restoration filtration component 3, a lifting mechanism 6, and an emergency fall prevention mechanism 7.

[0042] In this embodiment, the filter tank body 1 is used for water quality remediation in aquatic ecological environment research, and an inlet 2 is integrally connected to the upper part of one end of the filter tank body 1; the inlet 2 is the entrance for water to enter the filter tank, guiding the water to be treated into the filter tank body 1, which helps to evenly distribute the water flow and avoid excessive local pressure leading to reduced filtration efficiency.

[0043] In this embodiment, the water ecological restoration filtration component 3 includes a U-shaped frame plate 4 that is submerged and installed inside the cavity of the water filter tank body 1, and a multi-stage filtration component 5 installed in the U-shaped frame plate 4. By physically intercepting and removing suspended impurities in the water, the water quality purification level is improved, and the aquatic ecological environment is improved. The submerged installation of the U-shaped frame plate 4 and the multi-stage filtration component 5 does not immerse them in the water. There is a safe space between the inclined collection filter screen 19 and the final highest water level in the cavity of the water filter tank body 1, so that the inclined collection filter screen 19 will not immerse itself in the water, preventing impurities from being floated and washed back into the water.

[0044] In this embodiment, the lifting mechanism 6 is positioned above the filter tank body 1 and the U-shaped frame plate 4. When the lifting mechanism 6 drives the U-shaped frame plate 4 to rise, it facilitates the cleaning of impurities within the U-shaped frame plate 4 and the replacement of the multi-stage filter components 5. The U-shaped frame plate 4 supports and secures the multi-stage filter components 5, providing a stable installation platform for the filter screen and allowing for overall lifting for maintenance, thus enhancing the stability of the filter assembly and facilitating cleaning. The multi-stage filter components 5 filter particles of different sizes layer by layer, gradually reducing impurities in the water and improving the final effluent quality.

[0045] In this embodiment, the emergency fall protection mechanism 7 is symmetrically arranged inside the water filter tank body 1 and located on both sides of the U-shaped frame plate 4. When the U-shaped frame plate 4 is raised, the emergency fall protection mechanism 7 extends into the inner cavity of the water filter tank body 1 to support the bottom of the U-shaped frame plate 4. The emergency fall protection mechanism 7 provides safety assurance during the lifting process, increases the safety factor of equipment operation, and protects the safety of personnel and equipment.

[0046] In this embodiment, the water flowing into the inlet 2 impacts the multi-stage filter component 5, and the impurities trapped by the multi-stage filter component 5 slide down into the impurity collection box 15 inside the U-shaped frame plate 4.

[0047] In this embodiment, the multi-stage filtration component 5 includes a first filter screen 16, a second filter screen 17, and a third filter screen 18 with gradually decreasing pore size. The first filter screen 16 is adjacent to the inflow end of the water inlet 2.

[0048] In this embodiment, the lower parts of the first filter screen 16, the second filter screen 17, and the third filter screen 18 are all integrally connected to a sliding filter screen portion 34. The first filter screen 16, the second filter screen 17, and the third filter screen 18 have an angle with their respective sliding filter screen portions 34 for impurities to slide off. The first filter screen 16, the second filter screen 17, and the third filter screen 18 filter particles of different sizes layer by layer. Corresponding to different pore sizes, they form a graded filtration mechanism. This effectively removes various types of impurities and improves water quality.

[0049] In this embodiment, an inclined collection filter 19 is provided in the inner cavity of the impurity collection frame 15. The inclined collection filter 19 is inclined in the same direction as the sliding filter part 34, and the pore size of the inclined collection filter 19 is smaller than that of the third filter 18. The impurity collection frame 15 collects the filtered solid waste, centrally stores the impurities, facilitates subsequent cleaning, reduces the amount of manual cleaning, and improves work efficiency. The inclined collection filter 19 further filters fine particles, has a certain inclination angle, promotes the downward sliding of impurities, optimizes the impurity collection efficiency, and reduces the possibility of clogging.

[0050] In this embodiment, both ends of the U-shaped frame plate 4 are integrally connected to hanging ear plates 36 that can be hung on the top edge of the filter tank body 1. Support blocks 9 for supporting the U-shaped frame plate 4 are fixed on both inner walls of the filter tank body 1. The support blocks 9 are located on the inner wall of the filter tank, supporting the U-shaped frame plate 4 and maintaining the horizontal position of the U-shaped frame plate 4 under normal working conditions, ensuring that the filtration process is stable.

[0051] In this embodiment, inverted L-shaped columns 8 are fixed on both outer walls of the water filter tank body 1 near the water inlet 2, and the top of each L-shaped column 8 is integrally connected to an extension ear plate 26.

[0052] In this embodiment, the lifting mechanism 6 includes a rotating shaft 27 rotatably mounted between two extension ear plates 26, a winding drum 28 fixedly sleeved around the rotating shaft 27, a steel wire rope 30 wound around the winding drum 28, and a servo motor 29 fixed to the outer wall of one of the extension ear plates 26; the output shaft of the servo motor 29 is fixedly connected to one end of the rotating shaft 27.

[0053] In this embodiment, an inverted U-shaped hanger 32 is welded to the top surface of each of the two hanging ear plates 36, and a supporting hanger 33 is welded between the two U-shaped hangers 32. A hanging ring 31 is fixed at the middle position of the top surface of the supporting hanger 33, and the free end of the wire rope 30 is connected to the hanging ring 31.

[0054] In this embodiment, L-adjustment rods 20 are welded to the top surfaces of both ends of the second filter screen 17 and the third filter screen 18. Each L-adjustment rod 20 is hung on the top surface of the hanging ear plate 36. The second filter screen 17 and the third filter screen 18 can adjust the distance between themselves and the first filter screen 16 according to the size of the water flow 35. The L-adjusting rod 20 can slide rubbing against the top surface of the ear plate 36. Each ear plate 36 has symmetrically welded stops 21 on both sides of its top surface. A positioning rod 23 for penetrating the L-adjusting rod 20 is welded between adjacent stops 21. When adjusting the spacing between the first filter screen 16, the second filter screen 17, and the third filter screen 18, the L-adjusting rod 20 simply slides along the linear guide of the positioning rod 23 to adjust the spacing. After adjustment, the L-adjusting rod 20 is fixedly connected to the ear plate 36 by locking bolts 22. When the water flow 35 input from the inlet 2 is rapid, the water flow 35 can flow through each clamp of the first filter screen 16, the second filter screen 17, and the third filter screen 18. The angle between the first filter screen 16, the second filter screen 17, and the third filter screen 18 facilitates the downward sliding of impurities from the sliding filter screen section 34. When the water flow 35 entering from the water inlet 2 is slow, the distance between the three screens needs to be shortened. This distance is adjusted by sliding the L-adjustment rod 20, allowing the water flow 35 to pass through each angle of the first filter screen 16, the second filter screen 17, and the third filter screen 18. This ensures that impurities can easily slide downward from the sliding filter screen section 34. Therefore, regardless of whether the water flow 35 is rapid or slow, adjusting the distance between the three screens ensures uniform filtration and effective impurity removal. The sliding filter screen section 34, located below each filter screen, has an angle that promotes the smooth downward sliding of filtered impurities, facilitating effective collection and reducing the risk of clogging.

[0055] In this embodiment, the L-adjusting rod 20 and the positioning rod 23 allow for adjustment of the distance between each stage of the filter screen. The spacing can be adjusted according to the different water flow speeds to optimize the filtration effect, adapt to the filtration needs under different conditions, and improve flexibility.

[0056] In this embodiment, fixed sleeves 10 are symmetrically fixed on both outer walls of the filter tank body 1. The inner cavity of the fixed sleeve 10 extends into the inner cavity of the filter tank body 1. Each fixed sleeve 10 is connected to a detachable end cap 11 by a detachable bolt 14 at one end away from the filter tank body 1. The emergency fall prevention mechanism 7 includes a hydraulic push-pull rod 13 fixedly installed on the inner wall of each detachable end cap 11 and a fall prevention support shaft 12 fixedly installed on the free end of each hydraulic push-pull rod 13. The free end of the fall prevention support shaft 12 can extend into the inner cavity of the filter tank body 1 through the extension of the hydraulic push-pull rod 13, thereby supporting the raised U-shaped frame plate 4, so that the U-shaped frame plate 4 is pressed down on the fall prevention support shaft 12. Each L-shaped column 8 has a longitudinally formed positioning stroke groove 24 on its upper inner wall. Each hanging ear plate 36 has a positioning stroke slider 25 bolted to its top surface. The positioning stroke slider 25 fits into the positioning stroke groove 24. When the U-shaped frame plate 4 is raised and lowered, the positioning stroke slider 25 slides within the positioning stroke groove 24 for positioning the U-shaped frame plate 4 during raising and lowering. The positioning stroke groove 24 and the positioning stroke slider 25 guide the raising and lowering trajectory of the U-shaped frame plate 4, ensuring that the U-shaped frame plate 4 moves along a predetermined path, enhancing the controllability of the lifting process and improving safety.

[0057] In this embodiment, a PLC for controlling the opening and closing of the servo motor 29 and the hydraulic push-pull rod 13 is installed on the outside of the filter tank body 1. The PLC model can be selected according to actual needs. In this utility model, the PLC model is S7-200, which has the advantages of high reliability, strong anti-interference ability and convenient maintenance.

[0058] Working principle:

[0059] In this aquatic ecological restoration ecological water filtration pond, the water to be treated enters the water filtration pond body 1 through the inlet 2. The design of the inlet 2 helps to evenly distribute the water flow and avoid excessive local pressure. The water flow first comes into contact with the first filter screen 16, which is the first layer in the multi-stage filtration component 5. It has a large pore size and can intercept larger suspended solids and particles. The impurities intercepted by the first filter screen 16 will slide down the sliding filter screen part 34 to the impurity collection frame 15 at the bottom of the U-shaped frame plate 4.

[0060] After passing through the first filter screen 16, the water continues to flow to the second filter screen 17. The pore size of the second filter screen is smaller than that of the first filter screen, which can capture finer particles. The L-adjustment rod 20 can adjust the distance between the second filter screen 17 and the first filter screen 16 according to the change of water flow speed to optimize the filtration effect.

[0061] Finally, the water flows through the third filter 18, which is the finest filter and can remove very fine particles. All the impurities that are intercepted will slide down the filter section 34 into the impurity collection box 15.

[0062] The impurity collection frame 15 is located at the bottom of the U-shaped frame plate 4 and is used to collect impurities that slide down from each level of filter screen. The inclined collection filter screen 19 is set inside the impurity collection frame 15. Its pore size is smaller than that of the third filter screen 18, which can further filter out fine particles and guide these particles to slide into the bottom of the collection frame.

[0063] After multi-stage filtration, purified water flows out from the outlet of the filter tank body 1, completing the entire purification process. When cleaning or replacing the filter screen is required, the servo motor 29 drives the rotating shaft 27 to rotate, and the steel wire rope 30 on the winding drum 28 lifts the U-shaped frame plate 4 together with the multi-stage filtration components 5 out of the water surface. During the lifting process, the hydraulic push-pull rod 13 of the emergency fall prevention mechanism 7 extends from the fall prevention support shaft 12 to prevent the U-shaped frame plate 4 from falling unexpectedly. The positioning stroke groove 24 and the positioning stroke slider 25 ensure the stability and accuracy of the U-shaped frame plate 4 during the lifting process.

[0064] Staff can easily clean the impurities in the impurity collection box 15 and check or replace the filter. After cleaning, the U-shaped frame plate 4 is lowered back to its original position by the reverse operation of the servo motor 29, and the filtration process restarts.

[0065] Depending on the actual water flow conditions, the distance between each filter screen can be adjusted using the L-adjusting rod 20 to adapt to different flow rates and ensure optimal filtration. The locking bolt 22 secures the adjusted position, ensuring stability.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
