Under the guidance of the water flow, some organisms will be guided to the biological packing module. The living environment in this module is not suitable for the survival of organisms. Furthermore, due to the presence of various guide walls, it is not easy for organisms to escape. Large impurities will carry organisms to the purification module, resulting in an increased mortality rate of organisms. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This application uses a biological guidance channel to guide organisms that have accidentally entered the vicinity of the purification equipment.

[0024] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0025] Please see Figure 1-3 As shown, a solar-powered in-situ purification device for polluted rivers and lakes includes a first filter tank 2, a second filter tank 3, a collection tank 4, and a separable collection device 5 for collecting pollutants. First, the water flow guides impurities into the first filter tank 2 for preliminary treatment. Then, the impurities enter the second filter tank 3, where biological organisms are guided out. After the organisms are guided out of the purification device, the impurities are guided into the collection tank 4 until they enter the separable collection device 5. The impurities in the separable collection device 5 are then discharged, achieving impurity collection. Finally, the impurities in the separable collection device 5 are discharged into the in-situ purification device for further treatment.

[0026] Specifically, in this application, the first filter pool 2 is used to allow large impurities, small impurities and biological materials to pass through, and then the second filter pool 3 is used to discharge the biological materials and push the large impurities and small impurities into the collection pool 4. Therefore, in this process, the biological materials can be guided out, and the impurities can be collected and treated at the same time.

[0027] Therefore, this application sets three sets of water flow directions: the first water flow direction is parallel to the first filter tank 2, the second filter tank 3, and the collection tank 4, used to push impurities from the first filter tank 2 into the interior of the second filter tank 3, and from the second filter tank 3 into the interior of the collection tank 4; the second water flow direction is perpendicular to the second filter tank 3, vertically upward relative to the bottom, used to provide an upward water flow. In this process, the upward water flow is relatively weak and it is difficult to drive impurities to move too far upward, but organisms themselves like to move along the direction of the water flow, so this process can ensure that the organisms swim to the position of the third water flow direction; the third water flow direction is parallel to the first water flow direction, but the water flow height of the third water flow direction is higher than that of the first water flow direction, used to guide the organisms out from the third water flow direction. At this time, the effect of the first water flow direction can be used to guide and clean the impurities.

[0028] The first filter tank 2 has a small-sized screen plate 7 at its inlet, and a large-sized screen plate 10 on top of it. A matching screen plate 8 is also provided on the side of the small-sized screen plate 7. The height of the matching screen plate 8 is adjustable, and it interacts with both the small-sized screen plate 7 and the large-sized screen plate 10. In use, the matching screen plate 8 acts on the small-sized screen plate 7, causing impurities and organisms to move onto both the small-sized screen plate 7 and the large-sized screen plate 10. Small impurities pass through the matching screen plate 8 and the small-sized screen plate 7 and enter the interior of the first filter tank 2. Large impurities and organisms are impacted by the small-sized screen plate 7, or larger impurities and organisms at higher heights enter the interior of the first filter tank 2 through the large-sized screen plate 10. Under the influence of the first water flow direction and the organisms' own swimming ability, they move to the position of the large-sized screen plate 10 and into the second filter tank 3. Subsequently, under the influence of the second water flow direction, they continue to move... The organisms float to the surface until they reach the direction of the third water flow. This third water flow guides the organisms out of the second filtration tank 3, preventing them from participating in the impurity purification process and effectively protecting the aquatic organisms. Large impurities, under gravity, fall onto the side of the mesh plate 8. The mesh plate 8 then moves longitudinally onto the first large-size mesh plate 10, causing the large impurities to pass through the first small-size mesh plate 7 and enter the first filtration tank 2. During this process, the entry of external impurities is stopped, and only the current impurities are processed. The size of the first small-size mesh plate 7 is slightly smaller than the size of the first large-size mesh plate 10, but larger than the size of the mesh plate 8. When the mesh plate 8 overlaps with the first small-size mesh plate 7, the large impurities accumulate on the mesh plate 8 under gravity. Larger organisms pass through the first large-size mesh plate 10 and reach the interior of the second filtration tank 3, achieving initial separation of organisms and impurities.

[0029] Furthermore, a sealing base plate 6 is provided at the bottom of the first filter tank 2. The sealing base plate 6 can move longitudinally. When the sealing base plate 6 moves longitudinally to the connection part of the first small-size mesh plate 7 and the first large-size mesh plate 10, it cooperates with the mesh plate 8 to move longitudinally onto the first large-size mesh plate 10, thus blocking the first large-size mesh plate 10. At this time, large impurities are pushed into the interior of the first filter tank 2 by the first water flow direction, and the sealing base plate 6 and the first small-size mesh plate 7 form a passage for large impurities to pass through, thereby enabling the large impurities to be moved into the interior of the second filter tank 3, thereby guiding the large impurities.

[0030] Therefore, in order to guide the movement of large impurities, a second small-sized mesh plate 26 is fixed on the side of the first filter tank 2, and a second large-sized mesh plate 25 is fixed on the second small-sized mesh plate 26. The second small-sized mesh plate 26 is used to allow impurities to pass through, and the presence of the second large-sized mesh plate 25 is used to guide the organisms through, thereby enabling the organisms to be guided in the second filter tank 3.

[0031] As a further embodiment of this application, a small-sized frame 17 is provided inside the second filter tank 3, wherein the two ends of the small-sized frame 17 are connected, and mesh holes are evenly opened around the small-sized frame 17. The height of the small-sized frame 17 is adjustable. A bottom drainage device 16 for providing a second water flow direction is fixed on the small-sized frame 17. At the same time, a third large-sized mesh plate 27 is fixed on the side of the second filter tank 3, wherein a fourth large-sized mesh plate 28 is fixed on the third large-sized mesh plate 27. A third small-sized mesh plate 29 is provided on the small-sized frame 17 for cooperating with the fourth large-sized mesh plate 28. That is, when the organism is covered by the third large-sized mesh plate... When the organism is guided to the position of the second filter tank 3, it is guided out by the second direction water flow provided by the bottom drainage device 16 on the small frame 17. After a period of guidance, the small frame 17 is controlled to move longitudinally until the third small screen 29 is removed from the fourth large screen 28. At this time, impurities can pass through the second small screen 26 to reach the third large screen 27. At the same time, due to the presence of the small frame 17, the impurities can pass through the third large screen 27 and then be transferred from the fourth large screen 28 to the inside of the collection tank 4, so as to be collected by the separable collection device 5.

[0032] In this application, when the small frame 17 is lowered to the lowest point, it is used to allow small impurities to move from the first filter tank 2 to the interior of the second filter tank 3, and then to the interior of the collection tank 4, where the small impurities are collected. When the small frame 17 is moved to the highest point, it can push the remaining organisms inside the second filter tank 3 upwards, and at the same time, it can form two passageways, both of which can allow large impurities to pass through, making it convenient to collect the impurities using the collection tank 4.

[0033] As a further embodiment of this application, in order to achieve longitudinal movement of the small-sized frame 17 and longitudinal movement of the sealing base plate 6 and the mating mesh plate 8, a first traction chain 9 is fixed on the mating mesh plate 8, and a second traction chain 12 is fixed on the sealing base plate 6. Two sets of the second traction chains 12 are provided. A third traction chain 18 is fixed on one side of the small-sized frame 17. The first traction chain 9, the second traction chain 12, and the third traction chain 18 are fixedly installed on the top traction plate 13. A fourth traction chain 19 is fixed at the other end of the small-sized frame 17. Mounted on the movable support plate 21, a balancing mechanism for position stabilization is provided at the other end of the movable support plate 21. Therefore, in this application, the top traction plate 13 and the movable support plate 21 are respectively installed at the output end of the longitudinal moving device. The longitudinal moving device includes, but is not limited to, power equipment such as a traction power chain and a traction power roller. That is, the traction power roller is driven by a power motor to realize the retraction and extension function of the traction power chain, which is used to realize the longitudinal movement of the top traction plate 13 and the movable support plate 21 installed at the end of the traction power chain, thereby realizing the longitudinal movement of the mating mesh plate 8, the sealing base plate 6 and the small frame 17.

[0034] Specifically, the balancing mechanism includes a balancing base 23, on which a gravity balancing block 24 is slidably disposed. The gravity balancing block 24 is made of cast concrete and is fixedly installed on a movable support plate 21. In this application, the gravity balancing block 24 with a certain weight is used to achieve the gravity balancing function of the movable support plate 21. In this application, the overall power of the equipment comes from the combined action of solar power generation equipment and external power grid, thereby maintaining the stable operation of the water treatment equipment.

[0035] In this application, the bottom drainage device 16 uses the combined action of a water pump and an output pipe. That is, the water pump is installed in a fixed position, but the output end of the water pump is provided with an output pipe. There are two sets of output pipes. One set is fixedly installed on the small frame 17, and the other set is installed on the top drainage device 15.

[0036] Specifically, a fixed support base 14 is fixed to the top of the second large-size mesh plate 25, and a top drainage device 15 is fixed on the fixed support base 14. The water flow output by the output pipe realizes the third-direction water flow, which is used to guide the discharge of organisms. A fixed baffle 20 is fixed to the top of the fourth large-size mesh plate 28. The height of the fixed baffle 20 is the same as the height of the fixed support base 14. When the second-direction water flow acts on the organisms, if there are impurities, they will move upward with the action of the second-direction water flow until the action of the second-direction water flow weakens. The impurities will be blocked by the fixed baffle 20. The organisms will move upward due to their own perception of the water flow direction. So when the second-direction water flow stops, the impurities will fall back onto the small-size frame 17. By using the activation of the first-direction water flow, the impurities will enter the collection tank 4 for collection.

[0037] In use, the present invention first utilizes the action of the first direction water flow to carry impurities and organisms into the side of the first filter tank 2. Then, the organisms are guided by the first direction water flow to the first large-size mesh plate 10, thereby allowing the organisms to enter the interior of the first filter tank 2. Meanwhile, small impurities enter the first small-size mesh plate 7, and then pass through the second small-size mesh plate 26 into the interior of the second filter tank 3. Subsequently, the small impurities pass through the small-size frame 17 into the interior of the collection tank 4 to achieve direct collection of small impurities.

[0038] Subsequently, during this process, large impurities are retained on the side of the first small-sized mesh plate 7 under the action of gravity. At this time, the organisms enter the interior of the second filter tank 3. Under the action of the bottom drainage device 16, an upward water flow is applied, that is, under the action of the second water flow direction, a weak upward water flow guides the organisms. When the organisms move to a position above the fixed baffle 20 under the action of the water flow, the organisms are guided out of the interior of the second filter tank 3 under the action of the third water flow direction.

[0039] Subsequently, the top traction plate 13 and the movable support plate 21 are longitudinally moved using a power device. At this time, the mesh plate 8 covers the first large-size mesh plate 10, and the small-size frame 17 moves to the highest point. At this time, external impurities stop entering the equipment, that is, the amount of impurities flowing to the side of the first filter tank 2 will no longer increase. Under the action of the first water flow direction, large impurities pass through the first small-size mesh plate 7 and enter the interior of the first filter tank 2. At this time, under the action of the sealing bottom plate 6, the first small-size mesh plate 7 and the second small-size mesh plate 26 form a flow channel for large impurities, which makes it easy to use the large water flow thrust to push the impurities into the interior of the second filter tank 3. Then, the impurities pass through the third large-size mesh plate 27 and reach the interior of the collection tank 4, thereby enabling the separable collection device 5 to collect the impurities. In this application, the guidance of the water flow direction facilitates the guidance of organisms, which solves the problem of organisms being trapped in the equipment and dying.

[0040] In this application, the mesh size of the first small-sized mesh plate 7 is the same as that of the second small-sized mesh plate 26, which is used to guide the passage of large impurities. The mesh sizes of the first large-sized mesh plate 10, the second large-sized mesh plate 25, and the fourth large-sized mesh plate 28 are the same, which is used to guide the passage of large impurities and larger organisms. The mesh sizes of the mesh plate 8, the third small-sized mesh plate 29, and the small-sized frame 17 are the same, which is used to allow the passage of small impurities and prevent the passage of large impurities and larger organisms. By guiding larger organisms, this application can reduce the mortality of larger organisms.
