Description

Technical Field

[0001] This utility model relates to the field of ecological restoration, specifically a fountain structure for ecological restoration of eutrophication in landscape lakes. Background Technology

[0002] Eutrophication of landscape lakes, a prevalent environmental challenge, stems from the excessive accumulation of key nutrients such as nitrogen and phosphorus in the water. This imbalance directly induces the abnormal proliferation of algae and other aquatic plants, with obvious consequences: a sharp decline in water transparency and loss of clarity. More seriously, the excessive growth of these plants consumes large amounts of dissolved oxygen at night or during decomposition, leading to oxygen depletion in the water. This directly threatens the survival of aquatic organisms such as fish and benthic organisms, disrupting the already fragile ecological balance. Furthermore, eutrophication significantly increases the probability of harmful algal blooms. These explosive algae blooms not only produce unpleasant odors and affect the landscape experience, but more importantly, they may synthesize and release algal toxins, which pose a significant potential threat to aquatic life and even human health.

[0003] Most existing landscape lake eutrophication ecological restoration fountains often suffer from the ingress and blockage of water pumping pipes by floating or suspended aquatic plants, algae, and other organic debris, leading to decreased pump efficiency and secondary pollution of the water flow. Ultimately, this reduces the operational efficiency and stability of the entire ecological restoration system. Therefore, we propose a landscape lake eutrophication ecological restoration fountain structure to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fountain structure for the ecological restoration of eutrophication in landscape lakes, which solves the problem that existing fountains are easily clogged by debris, leading to low pump efficiency and secondary water pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fountain structure for ecological restoration of eutrophication in a landscape lake, comprising a water inlet tank, a filter screen installed on the inner wall of the water inlet tank, multiple water inlets on the outer surface of the water inlet tank, multiple water inlet holes on the upper surface of the water inlet tank, a protective box installed on the upper surface of the water inlet tank, a first motor installed on the inner bottom wall of the protective box, a rotating rod installed at the output end of the first motor after passing through the protective box and the water inlet tank, and multiple stirring rods installed on the outer surface of the rotating rod.

[0006] Furthermore, a protective box is installed on the upper surface of the water inlet tank, a porous biological carrier is installed on the inner bottom wall of the protective box, and an aerator is installed on the upper surface of the protective box.

[0007] Furthermore, the output end of the aerator is connected to a transmission pipe, and the end of the transmission pipe away from the aerator passes through the protective box and is connected to an aeration nozzle.

[0008] Furthermore, an annular slide rail is installed on the outer surface of the protective box, a sliding block is slidably installed on the outer surface of the annular slide rail, a second motor is installed on the outer surface of the sliding block, a rotating column is installed at the output end of the second motor, and a brush roller is installed on the outer surface of the rotating column.

[0009] Furthermore, a fixing ring is installed on the outer surface of the protective box, and multiple connecting plates are installed on the outer surface of the fixing ring. The bottom surface of the multiple connecting plates is jointly equipped with a connecting ring.

[0010] Furthermore, a connecting box is mounted on the outer surface of one of the connecting plates, a battery is mounted on the inner bottom wall of the connecting box, and a controller is mounted on the inner wall of the connecting box.

[0011] Furthermore, two limiting plates are installed on the outer surface of the connecting ring, and multiple damping rods are installed on the side of the two limiting plates that are far apart from each other. The ends of each set of damping rods that are far apart from each other are fixed with a mounting plate. A spring is sleeved on the outside of each damping rod, and a floating plate is installed on the outer surface of the two mounting plates.

[0012] Compared with existing technologies, this utility model provides a fountain structure for the ecological restoration of eutrophication in landscape lakes, which has the following beneficial effects:

[0013] 1. This device uses a dual composite water inlet structure with an inlet and an inlet hole, combined with a filter screen installed on the inner wall, to intercept large particles of debris such as aquatic plants, dead branches, and large-diameter organic debris, thus avoiding clogging problems. The first motor drives the rotating rod and stirring rod to rotate at high speed, and the resulting vortex can break up algae clusters and fine organic debris in the water tank, preventing them from settling at the bottom of the water tank and forming an anaerobic sediment layer. This design avoids secondary pollution and also prevents the sediment from being carried into the subsequent biological treatment process by the water flow, ensuring the stability of the microbial degradation environment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 The landscape lake eutrophication ecological restoration fountain structure in this embodiment includes a water inlet tank 1, a filter screen 29 installed on the inner wall of the water inlet tank 1, multiple water inlets 2 opened on the outer surface of the water inlet tank 1, multiple water inlet holes 3 opened on the upper surface of the water inlet tank 1, a protective box 4 installed on the upper surface of the water inlet tank 1, a first motor 5 installed on the inner bottom wall of the protective box 4, a rotating rod 6 installed after the output end of the first motor 5 passes through the protective box 4 and the water inlet tank 1, and multiple stirring rods 7 are installed on the outer surface of the rotating rod 6.

[0022] The upper surface of the inlet tank 1 is fitted with a protective box 8. The inner bottom wall of the protective box 8 is fitted with a porous biological carrier 9, which can be made of modified polyurethane foam. After the pre-filtered water enters the protective box 8, it comes into full contact with the porous biological carrier 9. The functional microorganisms such as nitrifying bacteria, denitrifying bacteria, and polyphosphate-accumulating bacteria attached to the carrier surface decompose ammonia nitrogen, nitrate, and phosphate in the water through metabolism, converting nitrogen into nitrogen gas and releasing it. Phosphorus is absorbed and fixed by the microorganisms, achieving the biodegradation of nutrients. The upper surface of the protective box 4... An aerator 10 is installed on the surface. The output end of the aerator 10 is connected to a transmission pipe 11. The end of the transmission pipe 11 away from the aerator 10 passes through the protective box 8 and is connected to an aeration nozzle 12. The aerator 10 delivers the treated water to the aeration nozzle 12 through the transmission pipe 11 to form a fountain landscape. During the spraying process, the water comes into full contact with the air, which greatly increases the dissolved oxygen content. This provides an aerobic environment for the metabolism of aerobic microorganisms and promotes water circulation through water flow disturbance, avoiding the secondary release of nutrients caused by the anaerobic environment at the bottom.

[0023] The outer surface of the protective box 8 is equipped with an annular slide rail 13, and a sliding block 14 is slidably installed on the outer surface of the annular slide rail 13. A second motor 15 is installed on the outer surface of the sliding block 14, and a rotating column 16 is installed at the output end of the second motor 15. A brush roller 17 is installed on the outer surface of the rotating column 16. The controller 28 drives the second motor 15 to rotate the rotating column 16 and the brush roller 17. At the same time, the sliding block 14 moves slowly along the annular slide rail 13, so that the brush roller 17 periodically cleans the water inlet 2 on the water inlet tank 1 and the surrounding biological carrier. This can prevent these biological attachments from clogging the original pore structure of the biological carrier or hindering the necessary water flow, thereby ensuring that the microbial community attached to the carrier can continuously and efficiently perform its function of degrading pollutants, and ensuring that the efficiency of the entire biological treatment process remains stable.

[0024] The protective box 8 has a fixing ring 26 installed on its outer surface. Multiple connecting plates 27 are installed on the outer surface of the fixing ring 26. A connecting ring 18 is installed on the bottom surface of the multiple connecting plates 27. A connecting box 19 is installed on the outer surface of one of the connecting plates 27. A battery 20 is installed on the inner bottom wall of the connecting box 19. A controller 28 is installed on the inner wall of the connecting box 19. Two limiting plates 21 are installed on the outer surface of the connecting ring 18. Multiple damping rods 22 are installed on the opposite sides of the two limiting plates 21. A mounting plate 23 is fixed to the opposite ends of each set of damping rods 22. A spring 24 is sleeved on the outside of each damping rod 22. The outer surfaces of the two mounting plates 23 are... The device is equipped with a floating plate 25, and the connecting ring 18 is tightly fixed to the protective box 8 through the connecting plate 27, forming the main frame of the device. The floating plate 25 at the bottom plays a key role in buoyancy support, which enables the entire device to float stably on the lake surface. This design not only gives the device the flexibility to adapt to different water level changes and ensures that it can maintain an effective working position under various hydrological conditions, but also forms a buffer structure with the damping rod 22 and the spring 24, which can effectively absorb and mitigate the impact and vibration brought by wind and waves. This design improves the operational stability of the device in complex water environments and ensures that its function can be continuously and reliably performed.

[0025] The working principle of the above embodiment is as follows: First, lake water is smoothly introduced into the device through the water inlet 2 on the outer surface of the water inlet tank 1 and the water inlet hole 3 on the upper surface. During the water inlet process, the filter screen 29 on the inner wall of the device first activates its interception function, effectively filtering out large suspended debris such as aquatic plants and dead branches brought in by the water flow. Then, the first motor 5 starts, driving the rotating rod 6 connected to it and the stirring rod 7 configured on it to rotate at a high speed. This dynamic process can effectively inhibit the sedimentation and accumulation of algae and other small organic debris at the bottom of the tank, creating favorable conditions for subsequent treatment.

[0026] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
