Description

Technical Field

[0001] This invention relates to the field of ecological floating fountain technology, and in particular to a floating fountain device that can create multiple water features. Background Technology

[0002] A floating fountain is a water feature device with all equipment integrated on a buoyancy platform, floating on the water surface. It creates a landscape by directly drawing water from the water body itself and spraying it. However, most urban artificial lakes are closed or semi-closed slow-flowing water bodies with long water exchange cycles and extremely low self-purification capacity, making them prone to eutrophication. Usually, a biological treatment structure is set on the floating fountain device to decompose nitrogen, phosphorus and organic matter in the water on-site. This makes the floating fountain device have the dual functions of landscape and water purification, and can stabilize the lake water quality in the long term.

[0003] For example, Chinese patent publication number CN211198763U discloses a framework structure for urban river landscape water management, including floating platforms set in shallow water areas on both sides of the river and water circulation fountains set on the riverbed; the water circulation fountains are located at one end of the floating platforms; a culture medium is placed inside the floating platforms, and aquatic plants are planted in the culture medium; an interception net is set on the side of the water circulation fountain away from the floating platforms, and an interception net is set on the other end of the floating platforms; a viewing area is formed between the interception nets, and fish fry are released in the viewing area.

[0004] The above-mentioned device uses aquatic plants and fish fry to achieve biological water purification and provides oxygen through the fountain. However, when the floating fountain device is used in eutrophic lakes, aquatic plants will gather at the water inlet when the fountain sprays water, and aquatic plants and other debris will accumulate near the filter screen, which is difficult to discharge and can easily block the water flow, causing the filter screen to become clogged. Regular manual cleaning is required, which is costly. In addition, the long-term oxygen supply through the fountain has a significant impact on the ecological environment of the lake and affects the survival of fish. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art where aquatic plants and other debris accumulate near the filter screen, easily obstructing water flow and causing filter screen blockage, and the long-term oxygen supply of the fountain causes significant disturbance to the ecological environment of the lake. The invention proposes a floating fountain device that can form multiple water features.

[0010] Preferably, the driving component includes a first motor fixedly connected inside the mounting housing, the output end of the first motor being fixedly connected to the equipment housing via a bracket, a planetary gear drive structure being provided inside the equipment housing, a rotating disk being fixedly connected to one end of the equipment housing, and the rotating disk being rotatably connected to the inner wall of the mounting housing, multiple sets of the second crushing components being disposed through the equipment housing and the rotating disk, and the water inlet of the pumping unit being disposed between the fixed ring and the rotating disk.

[0011] Preferably, the first crushing component includes a second motor that is fixedly connected through the mounting plate, an embedded rod is fixedly connected to the output end of the second motor, a sliding rod is slidably connected to one end of the embedded rod, and a protrusion that engages with the inner wall of the sliding rod is fixedly provided on the outer surface of the embedded rod.

[0015] Preferably, the filler assembly includes a second floating ring arranged annularly at intervals outside the first floating ring, and multiple sets of biological filler balls are fixedly installed between the second floating ring and the first floating ring by elastic ropes. A connecting rope is fixedly connected to the lower end of the second floating ring, and the connecting rope is connected to a winding structure set on the lake bottom.

[0016] Compared with existing technologies, the advantages of this invention are: 1. The present invention, through the arrangement of the water inlet component, the first crushing component and the second crushing component, ensures that during the fountain process of the CNC nozzle, multiple sets of second shear blades continuously contact and separate, which can cut large pieces of aquatic plants that come into contact with them. The slow rotation speed can prevent the aquatic plants from being excessively cut into fragments and embedded in the filter holes, thus clogging them. This not only prevents large pieces of aquatic plants from overlapping and wrapping around the outer surface of the second shear blades, thus blocking the flow of lake water, but also reduces the adhesion of aquatic plants through the scouring effect of the water flow when the multiple sets of second shear blades rotate slowly. This allows the water flow to remain unobstructed during the use of the CNC nozzle, facilitating the device to oxygenate the water and create a landscape. 2. This invention, through the arrangement of a filter assembly, an aeration section, and a packing assembly, and by switching between shearing and abrasive states by the first and second crushing components, not only prevents fountain blockage but also pre-treats and cuts aquatic plants, improving the efficiency of subsequent abrasive processing. During the fountain's intermittent periods, it attracts fish to gather and consume the ground aquatic plants. This not only treats the gathered aquatic plants, preventing large amounts of residual, decaying aquatic plants from clogging the filter holes and polluting the water, but also completes backwashing and cleaning of the filter holes while the pumping section drains water, reducing the frequency of manual cleaning. The aquatic plant debris serves as natural bait, combined with fish pheromones to induce fish to gather, constructing a benign ecological chain of aquatic plants, fish, and microorganisms. This not only reduces the need for artificial bait and lowers the input of external nitrogen and phosphorus but also gathers debris and fish feces in a high-microorganism concentration area near the biological packing ball, improving the efficiency and effectiveness of eutrophication treatment in lakes. At the same time, the ground aquatic plants are more easily decomposed by the microorganisms released by the biological packing ball, further improving the decomposition efficiency of the biological packing ball. 3. By setting up the packing components, the present invention allows the biological packing balls to be submerged underwater and float on the surface of the water when the temperature is high during the day and low at night, respectively. This avoids damage to the biological packing balls caused by high water surface temperature and direct sunlight. At the same time, it can effectively reduce disturbance to the water body, reduce interference with the nocturnal habitat of aquatic organisms, improve the environmental protection effect, and after fish excretion in the evening, there is a long time at night for the biological packing balls to decompose fully. It is less affected by additional factors such as fountains, thus improving the efficiency and effect of decomposition. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] like Figures 1-12 As shown, a floating fountain device capable of forming multiple water features includes a first floating ring 1 and a mounting frame 2 fixedly installed at the lower end of the first floating ring 1. A connecting pipe 3 is installed through the upper end of the mounting frame 2. Multiple sets of CNC nozzles 4 are arranged in a circular array at the upper end of the connecting pipe 3. A water inlet component 5 and a metering liquid outlet 9 are arranged at intervals on the mounting frame 2. The upper end of the water inlet component 5 is connected to the connecting pipe 3. A filter component 6 is arranged at the lower end of the water inlet component 5. An aeration section 7 is arranged below the filter component 6. Both the aeration section 7 and the first floating ring 1 are connected to the concrete anchor points on the lake bottom by anchor chains. The air inlet is connected to an external air pump. A packing assembly 8 is installed on the outside of the first float ring 1. The filter assembly 6 is used to grind up the accumulated aquatic plants and feed them to the fish. The water inlet assembly 5 is used to send lake water to the connecting pipe 3 and the CNC nozzle 4 for spraying. The height and angle of the sprayed water column can be adjusted by multiple sets of CNC nozzles 4, which can form a variety of water features. The aeration section 7 is used to aerate and increase the oxygen content in the water. At the same time, aeration can promote the floating of aquatic plant debris and the gathering of fish. The packing assembly 8 can degrade excess ammonia nitrogen, total phosphorus and organic pollutants in the water through nitrifying and denitrifying bacteria. The filter assembly 6 includes a mounting housing 61 located at the lower end of the water inlet assembly 5. A squeezing member 63 is inserted through one end of the mounting housing 61, and a pumping section 62 is inserted through the lower end of the mounting housing 61, with the outlet of the pumping section 62 located above the aeration section 7. A pushing member 64 is located on the left side inside the mounting housing 61. First crushing members 66 are inserted through both ends of the pushing member 64, and multiple sets of the first crushing members 66 are arranged in a circular array. A driving member 65 is spaced between the pushing member 64 and the squeezing member 63, with both ends of the driving member 65... The device is equipped with multiple sets of second crushing components 67, which are radially contacted by multiple sets of first crushing components 66 on the left side of the drive component 65. The push component 64 is used to move the multiple sets of first crushing components 66, and the drive component 65 is used to drive the multiple sets of second crushing components 67 to rotate. The multiple sets of first crushing components 66 and second crushing components 67 are used to cut and grind aquatic plants. The pumping unit 62 is used to pump out lake water containing aquatic plant debris from inside the mounting housing 61, and the squeezing component 63 is used to squeeze the lake water inside the mounting housing 61.

[0021] The water inlet assembly 5 includes a connecting housing 52 fixedly installed at the lower end of the mounting bracket 2. Water pumps 51 are fixedly installed through both sides of the connecting housing 52. The outlet end of the water pumps 51 is fixedly connected to the inlet end of the connecting pipe 3. The inlet end of the water pumps 51 is located inside the connecting housing 52. A first shut-off valve pipe section 53 is fixedly connected through the upper end of the connecting housing 52. The lower end of the connecting housing 52 is fixedly connected to the outer surface of the mounting housing 61. A second shut-off valve pipe section 54 is fixedly installed through the connecting housing 52 and the mounting housing 61. The water pumps 51 can transport the lake water inside the connecting housing 52 to the inside of the connecting pipe 3 for use by the CNC nozzles 4. The first shut-off valve pipe section 53 and the second shut-off valve pipe section 54 are used to control whether the upper and lower ends of the connecting housing 52 can be filled with or drained by lake water.

[0022] The pushing component 64 includes a first electric telescopic rod 641 fixedly connected inside the mounting housing 61. One end of the first electric telescopic rod 641 is fixedly connected to a mounting plate 642, and the mounting plate 642 is slidably embedded in the mounting housing 61 along the length direction of the mounting housing 61. Through holes 643 are provided at both ends of the mounting plate 642, and multiple sets of through holes 643 are arranged in annular intervals. Multiple sets of first crushing components 66 are located on the inner side of the annulus formed by multiple sets of through holes 643. The first electric telescopic rod 641 is used to drive the mounting plate 642 to move, thereby controlling the multiple sets of first crushing components 66 to move together.

[0023] The pushing component 64 also includes a fixing ring 644 fixedly connected inside the mounting housing 61, and the fixing ring 644 is located between the mounting plate 642 and the driving component 65. Multiple sets of through holes 643 coincide with the solid part of the fixing ring 644. When multiple sets of first crushing components 66 move linearly, they can all pass through the central opening of the fixing ring 644. When the mounting plate 642 moves and fits against the fixing ring 644, the fixing ring 644 and the mounting plate 642 can block each other, thereby preventing a large amount of water from flowing through the through holes 643 and the central opening of the fixing ring 644.

[0024] The drive component 65 includes a first motor 651 fixedly connected inside the mounting housing 61. The output end of the first motor 651 is fixedly connected to the equipment housing 652 via a bracket. A planetary gear drive structure is provided inside the equipment housing 652. A rotating disk 653 is fixedly connected to one end of the equipment housing 652, and the rotating disk 653 is rotatably connected to the inner wall of the mounting housing 61. Multiple sets of second crushing components 67 are disposed between the equipment housing 652 and the rotating disk 653. The water inlet of the pumping unit 62 is located between the fixed ring 644 and the rotating disk 653. The first motor 651 can drive the equipment housing 652 and the rotating disk 653 to rotate together, so that multiple sets of second crushing components 67 revolve around the axis of the first motor 651.

[0025] The first crushing component 66 includes a second motor 661 that is fixedly connected to the mounting plate 642. An embedded rod 662 is fixedly connected to the output end of the second motor 661. A sliding rod 663 is slidably connected to one end of the embedded rod 662. A protrusion that engages with the inner wall of the sliding rod 663 is fixedly provided on the outer surface of the embedded rod 662. When the embedded rod 662 rotates, the sliding rod 663 can be driven to rotate together through the protrusion.

[0026] A spring 666 is fixedly connected between the end of the embedded rod 662 and the inner wall of one end of the sliding rod 663. A grinding rod 664 is fixedly connected to the outer surface of the sliding rod 663, and the outer surface of the grinding rod 664 is wavy. Multiple sets of first shearing blades 665 are fixedly connected at intervals on the outer surface of the grinding rod 664. The spring 666 is used to push the sliding rod 663. Through the setting of the spring 666, the distance between the grinding rod 664 and the mounting plate 642 can be automatically adjusted under pressure. The angle of the grinding rod 664 and the multiple sets of first shearing blades 665 can be adjusted by the second motor 661, thereby controlling whether the first shearing blades 665 face the second crushing component 67.

[0027] The second crushing component 67 includes a rotating column 671 that is rotatably connected to the equipment housing 652 and the rotating disk 653. A grinding shell 672 is eccentrically fixed to one end of the rotating column 671, and the outer surface of the grinding shell 672 is wavy, interlocking with the outer surface of the grinding rod 664. Multiple sets of second shearing blades 673 are fixedly connected at intervals to the outer surface of the grinding shell 672, and these second shearing blades 673 are staggered with multiple sets of first shearing blades 665, with their sidewalls in contact. Multiple sets of filter holes 674 are formed through the outer surface of the grinding shell 672. It should be noted that... The planetary gear drive structure inside the equipment housing 652 drives multiple sets of rotating columns 671 to rotate synchronously, which is a known prior art. Those skilled in the art are capable of conceiving of the specific structure. The rotation of the rotating columns 671 can drive the grinding shell 672 and the second shearing blade 673 to rotate. Since the grinding shell 672 is eccentrically set at one end of the rotating column 671, its height will change after rotating 180 degrees, thereby switching between two states: the second shearing blade 673 and the first shearing blade 665 are in contact with the grinding rod 664 and the grinding shell 672.

[0028] Multiple sets of connecting holes are provided at intervals at both ends of the mounting housing 61. A second electric telescopic rod 631 is fixedly connected through the right end of the mounting housing 61. A push plate 632 is fixedly connected to one end of the second electric telescopic rod 631. A rubber layer is provided on the outer surface of the push plate 632, and the rubber layer is in contact with the inner wall of the mounting housing 61. After the second shut-off valve pipe section 54 is closed, the push plate 632 can be pushed by the second electric telescopic rod 631 to push the water inside the mounting housing 61 toward the pushing component 64.

[0029] The filler assembly 8 includes a second float ring 81 arranged annularly outside the first float ring 1. Multiple sets of biological filler balls 82 are fixedly installed between the second float ring 81 and the first float ring 1 by elastic ropes. A connecting rope 83 is fixedly connected to the lower end of the second float ring 81, and the connecting rope 83 is connected to a winding structure set on the lake bottom. The second float ring 81 can be moved up and down by pulling the connecting rope 83 through the winding mechanism. The biological filler balls 82 are used to decompose nitrogen, phosphorus and organic pollutants in the nearby water body and alleviate eutrophication. When the connecting rope 83 is loosened, the buoyancy of the second float ring 81 itself can pull the multiple sets of biological filler balls 82 upward, so that most of the biological filler balls 82 are exposed above the water surface. Conversely, it can make the biological filler balls 82 completely submerged in the water.

[0030] In this invention, the water pump 51 can continuously draw lake water from inside the connecting shell 52 into the connecting pipe 3, and then the CNC nozzle 4 can form water features of different shapes. On the one hand, it can meet the aesthetic requirements, and on the other hand, it can make the water body circulate and effectively reduce stagnant water areas. At the same time, the fountain can continuously oxygenate the lake water, break up the oxygen-deficient stratification of the upper and lower water bodies of the lake. Sufficient oxygen can allow a large number of nitrifying and denitrifying functional microorganisms to attach to the surface of the biological filler ball 82 and maintain the activity of the biofilm. The water flow can also remove the aging biofilm on the surface of the filler in time, prevent the filler pores from being blocked, give full play to the water purification function of the biological filler ball 82, improve the water quality of eutrophic lakes, and inhibit the growth of blue-green algae. When multiple sets of CNC nozzles 4 spray lake water, the lake water continuously enters the mounting housing 61. This keeps the first crushing component 66 and the second crushing component 67 in a shearing state, allowing the lake water to pass through the grinding shell 672 and enter the connecting housing 52 along the mounting housing 61 and the second shut-off valve pipe section 54. During this process, aquatic plants are blocked by the filter holes 674 between the rotating disk 653 and the mounting disk 642. Simultaneously, the first motor 651 causes multiple sets of second crushing components 67 to slowly revolve around the axis of the first motor 651. During this process, multiple... The second shearing blade 673 and multiple sets of second shearing blades 665 will continuously contact and separate, which can cut large pieces of aquatic plants that come into contact with them. The slow rotation speed can prevent the aquatic plants from being excessively cut into fragments and embedded in the filter holes 674, thus preventing them from clogging the filter. This not only prevents large pieces of aquatic plants from overlapping and wrapping around the outer surface of the second shearing blade 673, thus blocking the flow of lake water, but also reduces the adhesion of aquatic plants through the scouring effect of the water flow when the multiple sets of second shearing blades 673 revolve slowly. This allows the water flow to remain unobstructed when the digital nozzle 4 is in use, making it easier for the device to oxygenate the water and create aquascape. During the evening feeding season, the CNC nozzle 4 stops spraying. After the CNC nozzle 4 stops, both the second shut-off valve section 54 and the first shut-off valve section 53 are opened. Then, the first crushing component 66 and the second crushing component 67 are separated, and the mounting plate 642 is moved to contact the fixing ring 644, sealing both the through hole 643 and the central opening of the fixing ring 644. The water squeezed into the connecting shell 52 can be discharged through the first shut-off valve section 53. Then, the first shut-off valve section 53 and the second shut-off valve section 54 are closed, and the first crushing component 66 and the second crushing component 67 are switched to abrasive mode. Then, the first motor 651 causes multiple sets of second crushing components 67 to rotate rapidly. Since the grinding shell 672 and the grinding rod 664 are mutually... The fitting and compression of space by the mounting plate 642 make the aquatic plants denser. Since the aquatic plants have been cut into small pieces during fountain operation, the rapid friction between the grinding shell 672 and the grinding rod 664 can quickly grind the small pieces of aquatic plants into fragments. The wavy design of the grinding rod 664 and the grinding shell 672 not only grinds the aquatic plants but also increases the difficulty for large pieces of aquatic plants to adhere during the shearing process, further improving the anti-clogging effect. At the same time, a certain amount of fish pheromones are released into the lake water through the metering liquid outlet 9 to induce nearby fish to gather. The water and aquatic plants between the fixing ring 644 and the rotating plate 653 are slowly discharged to the top of the aeration section 7 through the pumping water section 62. At this time, the squeezing component 63 pushes the water inside the mounting shell 61, causing the equipment shell 652 to move to the right. Lake water from the side passes through the flow hole 675 and filter hole 674 to reach the left side of the rotating disk 653. During this process, multiple sets of filter holes 674 are flushed back, flushing the aquatic plant slime and debris attached to the water-facing end of the filter holes 674 back into the lake water on the left side of the rotating disk 653. When the second electric telescopic rod 631 extends a certain distance, the second shut-off valve pipe section 54 is located to the right of the push plate 632, causing the mounting plate 642 to separate from the fixing ring 644. At this time, external lake water can enter the mounting housing 61 and be discharged through the pump unit 62, reducing the residue of aquatic plant debris in the mounting housing 61. After the aquatic plant debris is discharged, continuous aeration can be carried out through the aeration unit 7. A large number of tiny bubbles can promote the suspension of aquatic plant debris in the water, effectively reducing the aquatic plant debris. The possibility of the debris settling and decomposing at the bottom is reduced, decreasing the likelihood of exacerbating eutrophication. Simultaneously, the oxygen introduced into the water through aeration attracts fish and provides the oxygen needed to decompose nitrogen and phosphorus in the biological filler balls 82, enhancing their water purification effect. With the continuous discharge of lake water and aquatic plant debris, and the gathering of fish, the debris serves as natural food. The fish continuously feed and excrete, and the excrement rises or remains suspended in the water due to the aeration bubbles. Since the outlets of the aeration unit 7 and the pump unit 62 are located below multiple sets of biological filler balls 82, unused small amounts of aquatic plant debris and fish excrement are collected near the biological filler balls 82, resulting in higher concentrations of microorganisms and dissolved oxygen near them.It exhibits better decomposition efficiency and effectiveness for fish feces and nitrogen and phosphorus in water, effectively preventing fish feces from scattering and accumulating in other locations, thus improving the treatment of eutrophication. Through the above methods, it can prevent fountain blockage while pre-treating and cutting aquatic plants, improving the efficiency of subsequent abrasive application. During fountain intervals, it attracts fish to gather and consume the chopped aquatic plants, not only treating the accumulated plants and preventing large amounts of residual, decaying aquatic plants from clogging the filter holes 674 and polluting the water, but also facilitating drainage from the pump unit 62. The backwashing and cleaning of filter holes 674 reduces the frequency of manual cleaning. Aquatic plant debris serves as natural food, and combined with fish pheromones to induce fish aggregation, creating a positive ecological chain among aquatic plants, fish, and microorganisms. This not only reduces the need for artificial food and external nitrogen and phosphorus input but also concentrates debris and fish waste in the high-microorganism concentration area near the biological filler ball 82, improving the efficiency and effectiveness of eutrophication control in the lake. Furthermore, the shredded aquatic plants are more easily decomposed by the microorganisms released from the biological filler ball 82, further enhancing its decomposition efficiency. During the day when the temperature is high, the second float ring 81 is moved downward by the winding device, immersing multiple sets of biological filler balls 82 in the water. The fountain and aeration unit 7 continuously supply oxygen to the biological filler balls 82, preventing damage to the biological filler balls due to high water temperature and direct sunlight. At night when the temperature is low, the connecting rope 83 is loosened by the winding device, allowing the second float ring 81 and most of the biological filler balls 82 to float to the surface. The biological filler balls 82 that float to the surface at night can directly contact the oxygen in the air. At this time, the CNC nozzle 4 and aeration unit 7 can switch to low-load mode or be partially shut down, which can effectively reduce disturbance to the water body and reduce interference with the nighttime habitat of aquatic organisms. In addition, after fish excrete in the evening, there is a longer period of time at night for the biological filler balls 82 to fully decompose, with less interference from additional factors such as the fountain, thus improving the efficiency and effect of decomposition.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
