Description

Technical Field

[0001] The invention relates to the field of reservoir landscape, in particular to a method for arranging a reservoir waterfall device with landscape function. Background Art

[0002] With the acceleration of urbanization and the increasing demand for ecological environment, more and more infrastructure not only needs to meet functional requirements, but also needs to be integrated into landscape design to enhance the beauty and ecological benefits of the environment. As a key facility for urban and agricultural water supply, regulation and flood control, the dam of a reservoir is usually constructed with hard materials such as concrete and stone, which has the characteristics of high stability and good anti-seepage effect. However, due to the hardened design, the dam of a traditional reservoir often appears monotonous and lacks integration with the natural environment, which is not conducive to the creation of a hydrophilic landscape and is difficult to meet the modern people's pursuit of water landscape aesthetics.

[0003] In order to enhance the landscape effect of reservoir dams, artificial waterfall devices have gradually become an effective means of landscape transformation in recent years. This device simulates the natural flow of water by arranging special waterfall generation equipment on the hard dam body, creating a dynamic waterscape effect, thereby creating a hydrophilic and pleasant landscape environment.

[0004] The Korean patent with the patent number KR102734941B1 provides an artificial waterfall device that does not splash water and can be approached at a close distance. Its main body is an inclined structure with a gap on the inclined surface. When in operation, water moves from top to bottom along the inclined surface and flows into the water tank below through the gap as it descends. The water tank receives and purifies the discharged water, and then transports it to the upper part of the inclined structure to circulate the water. Artificial waterfalls can not only add beauty to the surrounding environment, but also improve the local ecosystem, increase air humidity, reduce noise, and produce visual and auditory pleasure effects through the flow of water, enhancing the tourists' tour experience. Summary of the invention

[0005] The purpose of the present invention is to address the shortcomings of existing reservoir landscape construction and provide a reservoir waterfall device layout method with landscape function. The layout method can realize the ecological construction of reservoir landscape, combine artificial waterfalls with reservoirs and shape water landscapes, and recycle water used for landscaping, with low water circulation loss, effectively reducing the use of water resources.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: A reservoir waterfall device with landscape function comprises a reservoir dam body, a storage water body is arranged on one side of the reservoir dam body, a water spray module is arranged on the upper part of the reservoir dam body, the water spray module comprises a water spray structure, pressure nozzles are arranged in an array on the water spray structure, the pressure nozzle comprises a vertical control element, the pressure nozzle is fixed to the water spray structure through the vertical control element, the end of the vertical control element is hinged with a connecting element, the end of the connecting element is hinged with a horizontal control element, and a nozzle is fixed on the horizontal control element.

[0007] The present invention provides a reservoir waterfall device with landscape function. The water spraying structure is externally connected to a plurality of pressure nozzles, the pressure nozzles are outwardly expanded, and the water curtains sprayed by the plurality of pressure nozzles are connected to each other, thereby achieving the effect of an artificial waterfall. The pressure nozzles are connected to a control terminal, and the direction of the pressure nozzles can be adjusted according to landscape requirements.

[0008] Specifically, a pumping pipe is provided above the reservoir water body, the pumping pipe is connected to a three-way water pump, the water outlet of the three-way water pump is connected to a water spray structure through a water supply pipe, the water supply pipe has at least two branches; the three-way water pump is connected to a frequency converter. A water reservoir is provided at the bottom of the reservoir dam body, a circulating water pump is provided between the water reservoir and the reservoir water body, the circulating water pump is connected to the water reservoir through a circulating pumping pipe, and the circulating water pump is connected to the reservoir water body through a circulating drain pipe.

[0009] The present invention supplies the reservoir water to the water spraying structure at the top of the reservoir through a three-way water pump to generate a reservoir waterfall with landscape effect, and adopts a circulating water pump to transport the waterfall water flowing to the bottom water reservoir to the reservoir water to realize the recycling of the water, thereby constructing the hardened reservoir dam into an ecological hydrophilic site.

[0010] Among them, a water level meter is provided above the reservoir water body, and the water level meter is connected to the control terminal. The system will make judgments based on the changes in the water level: if the water level is lower than the set minimum value, the water supply power will be increased; if the water level exceeds the maximum value, the water supply power will be reduced; if the water level is within the normal range, the current power will be maintained. At the same time, the system dynamically adjusts the water supply flow rate according to the needs of landscape shaping to ensure the best landscape effect. The entire system is in a continuous feedback loop, constantly monitoring the reservoir water level and its changes, adjusting the water supply power and flow rate in real time, and ensuring that the waterfall device achieves a dynamic balance between water level and power while meeting landscape requirements.

[0011] Specifically, the reservoir is equipped with a water level monitoring device. When the water reaches the warning level, the stored water is circulated back to the reservoir through a circulating water pump to achieve the recycling of the water.

[0012] Optionally, a filter is provided between the water reservoir and the circulating water pump, the filter body is a cylinder with openings at both ends, the top, bottom and side of the cylinder are provided with filter screens, the top and bottom of the cylinder are respectively connected to the second and third rings, the inner walls of the second and third rings are provided with toothed convex strips with balls.

[0013] The present invention is provided with a filter to filter the water for recycling. Before the water in the reservoir enters the circulating water pump, the water first enters the filter for filtration. Due to the geometric constraint of the bracket on the cylinder, the cylinder can only rotate. The rotation of the cylinder is realized by the toothed convex strip with balls. When the water flows through the filter, the cylinder inside it rotates. The design of the toothed convex strip with balls can enable the cylinder to obtain a suitable rotation speed. During operation, due to the high flow rate in the pipe, some small particle impurities will enter the inside through the filter screen at the top of the cylinder. At this time, the water flow rate decreases, the impurities with low density float up, and the impurities with high density sink. The impurities are ejected from the filter screen on the side wall of the cylinder to the outside under the action of centrifugal force, and the water flows to the circulating water pump through the filter screen at the bottom of the cylinder, thereby achieving filtration. In order to avoid clogging of the side wall filter screen, a brush and a rubber blade are designed on the bracket, which can clean the filter screen when the cylinder rotates.

[0014] The steps of the arrangement method are as follows: A water spray module is arranged above the reservoir dam body; a reservoir water body is arranged on the side of the reservoir dam body, and the water spray module is connected to the reservoir water body, and the medium in the reservoir water body is discharged from the upper part of the reservoir dam body to the lower part of the reservoir dam body by the water spray module; a three-way water pump is arranged between the reservoir water body and the water spray module, and the water is led to the water spray module by the three-way water pump; a water reservoir is arranged below the formed waterfall, and the waterfall water in the water reservoir is transported to the reservoir water body by a circulating water pump; a filter is installed inside the water reservoir so that the water flows through the filter before flowing to the circulating water pump; a water level monitoring device is installed inside the water reservoir; a water level gauge is arranged above the reservoir water body; a control terminal is connected with the water level gauge, the frequency converter and the pressure nozzle, and the direction of the frequency converter and the pressure nozzle is controlled by water level feedback and landscape requirements.

The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0029] Embodiment 1 A reservoir waterfall device with landscape function: A reservoir waterfall device with landscape function comprises a reservoir dam body 10, a storage water body 20 is arranged on one side of the reservoir dam body 10, a water spray module is arranged on the upper part of the reservoir dam body 10, the water spray module comprises a water spray structure 31, pressure nozzles 32 are arranged in an array on the water spray structure 31, the pressure nozzles 32 comprise a vertical control element 321, the pressure nozzles 32 are fixed to the water spray structure 31 through the vertical control element 321, the end of the vertical control element 321 is hinged with a connecting element 322, the end of the connecting element 322 is hinged with a horizontal control element 323, and a nozzle 324 is fixed on the horizontal control element 323.

[0030] The present invention provides a reservoir waterfall device with landscape function. A water spraying structure 31 is externally connected to a plurality of pressure nozzles 32. The pressure nozzles 32 are outwardly expanded. Water curtains sprayed by the plurality of pressure nozzles 32 are connected to each other, thereby achieving the effect of an artificial waterfall. The pressure nozzles 32 are connected to a control terminal 70, and the direction of the pressure nozzles 32 can be adjusted according to landscape requirements.

[0031] Specifically, a pumping pipe 34 is provided above the reservoir water body 20, and the pumping pipe 34 is connected to a three-way water pump 33, and the water outlet of the three-way water pump 33 is connected to a water spray structure 31 through a water supply pipe 30, and the water supply pipe 30 has at least two branches; the three-way water pump 33 is connected to a frequency converter 35. A reservoir 40 is provided at the bottom of the reservoir dam body 10, and a circulating water pump 50 is provided between the reservoir 40 and the reservoir water body 20, and the circulating water pump 50 is connected to the reservoir 40 through a circulating pumping pipe 51, and the circulating water pump 50 is connected to the reservoir water body 20 through a circulating drain pipe 52.

[0032] The present invention supplies the reservoir water body 20 to the water spray structure 31 at the top of the reservoir through a three-way water pump 33 to generate a reservoir waterfall with landscape effect, and uses a circulating water pump 50 to transport the waterfall water flowing to the bottom water reservoir 40 to the reservoir water body 20 to achieve the recycling of the water body, thereby constructing the hardened reservoir dam into an ecological hydrophilic site.

[0033] Among them, a water level meter 60 is provided above the reservoir water body 20, and the water level meter 60 is connected to the control terminal 70. The system will make judgments based on the changes in the water level: if the water level is lower than the set minimum value, the water supply power will be increased; if the water level exceeds the maximum value, the water supply power will be reduced; if the water level is within the normal range, the current power will be maintained. At the same time, the system dynamically adjusts the water supply flow rate according to the needs of landscape shaping to ensure the best landscape effect. The entire system is in a continuous feedback loop, constantly monitoring the reservoir water level and its changes, adjusting the water supply power and flow rate in real time, and ensuring that the waterfall device achieves a dynamic balance between water level and power while meeting landscape requirements.

[0034] Specifically, the water reservoir 40 is equipped with a water level monitoring device 402. When the water reaches the warning level, the water is circulated back to the reservoir water body 20 through the circulating water pump 50, so as to realize the recycling of the water.

[0035] The device is easy to operate and has low production cost. It is integrated into the waterfall landscape and transforms the hardened reservoir dam into an ecological hydrophilic site.

[0036] Embodiment 2 Further optimization based on Example 1: Optionally, a filter 53 is provided between the water reservoir 40 and the circulating water pump 50. The main body of the filter 53 is a cylinder 535 with openings at both ends. The top, bottom and side of the cylinder 535 are provided with filter screens. The top and bottom of the cylinder 535 are respectively connected to the second ring 537 and the third ring 538. The inner walls of the second ring 537 and the third ring 538 are provided with toothed convex strips with balls. The second ring 537 and the third ring 538 are respectively connected to the first ring 536 and the fourth ring 539. The outer walls of the first ring 536 and the fourth ring 539 are provided with toothed convex strips with balls. They are all fixed to the bracket 531. The bracket 531 is provided with a groove in the vertical direction. The groove is provided with a brush 532 and a blade 533. The brush 532 and the blade 533 are connected to the bracket 531 through a spring 534. There are at least two blades 533, and the distances between adjacent cylinders 535 of the blades 533 are different.

[0037] The present invention is provided with a filter 53 to filter the recycled water. Before the water in the water reservoir 40 enters the circulating water pump 50, the water first enters the filter 53 for filtration. Due to the geometric constraint of the bracket 531 on the cylinder 535, the cylinder 535 can only rotate. The rotation of the cylinder 535 is achieved by the toothed convex strips with balls. When the water flows through the filter 53, the cylinder 535 therein rotates. The design of the toothed convex strips with balls can enable the cylinder 535 to obtain a suitable rotation speed. During operation, due to the high flow rate in the pipe, some small particles of impurities will enter the interior through the filter screen at the top of the cylinder 535. At this time, the flow rate of the water body decreases, impurities with low density float up, and impurities with high density sink. Under the action of centrifugal force, the impurities are ejected to the outside from the filter screen on the side wall of the cylinder 535, and the water flows to the circulating water pump 50 through the filter screen at the bottom of the cylinder 535, thereby achieving filtration. After the filter 53 is set inside the water reservoir 40, the drum 535 of the filter 53 forms a rotating motion in the water reservoir 40, which can have a rectifying effect on the water flow in the water reservoir 40. For the water body dropped into the water reservoir 40 for landscaping, the fluctuation of the water surface of the water reservoir 40 can be relatively stabilized, thereby reducing the splash or fluctuation of the water surface of the water reservoir 40, thereby reducing the loss of water body caused by gasification and splashing of the water body in the water reservoir 40. At the same time, in order to avoid clogging of the side wall filter screen, a brush 532 and a blade 533 made of rubber material are designed on the bracket 531, which can be used in the cylinder When the cylinder 535 rotates, its filter screen is cleaned. Specifically, the brush 532 is mainly used to clean broken leaves, hair scraps, bark, etc. During the rotation of the cylinder 535, the brush 532 relatively close to the cylinder 535 contacts the cylinder 535 to scrape its surface to achieve cleaning, and by controlling the distance between the brush 532 and the cylinder 535, it is avoided that too much contact surface causes the cylinder 535 to fail or be blocked. The blade 533 with a larger distance from the cylinder 535 is mainly used to clean the gravel sunk under the cylinder 535, and prevent the brush 532 from deforming during the continuous cleaning process, resulting in poor cleaning effect and impurities being deposited at the bottom of the cylinder 535. After the brush 532 with a smaller distance is deformed to a certain extent, the blade 533 with a relatively larger distance ensures the cleaning of the cylinder 535. In addition, by observing the use of the brush 532 and the blade 533, the deformation rate and filtering effect of the cylinder 535 can be judged.

[0038] Embodiment 3 Water level control method: The process first obtains the current reservoir water level through input parameters , Landscape requirements ,flow and key parameters of the pipeline (such as length ,diameter , Turning Angle , Turning radius Then, according to the material and flow rate of the pipe , calculate the friction coefficient , and then use the Darcy-Weisbach formula to calculate the head loss along the way :

[0039] in, is the acceleration due to gravity. At the same time, for the pipe bends, the local head loss also needs to be calculated. :

[0040] in, is the local head loss coefficient. Add the along-the-way and local head losses to get the total head loss :

[0041] In the power calculation stage, the actual power of the three-way water pump is calculated by combining the water level and flow rate with the total head loss. :

[0042] In the formula is the density of water. Then, the system will make a judgment based on the change of water level: if the water level is lower than the set minimum value, the water supply power will be increased; if the water level exceeds the maximum value, the water supply power will be reduced; if the water level is within the normal range, the current power will be maintained. At the same time, the system dynamically adjusts the water supply flow rate according to the needs of landscape shaping to ensure the best landscape effect and save water consumption. More importantly, the above-mentioned water level control calculation scheme can realize the monitoring of landscaping water use to solve the problem of water outage or excessive water volume that cannot be effectively monitored and fed back. The entire system is in a continuous feedback loop, constantly monitoring the water level of the reservoir and its changes, adjusting the water supply power and flow in real time, and ensuring that the waterfall device achieves a dynamic balance between water level and power while meeting the landscape requirements.
