Description

Technical Field

[0001] The invention relates to the technical field of water resource recovery management, and in particular to a water resource recovery management system and method for landscape gardening. Background Art

[0002] Urban landscaping plays an important role in improving the city's taste and creating a beautiful urban environment. However, in terms of water use in urban landscaping, there is a large amount of water resource consumption. "Energy-saving" gardens have become the mainstream direction of landscaping development. Water recycling, including automatic circulation and replenishment of water resources, is also a key content.

[0003] At present, most of the water bodies in urban gardens are relatively independent and directly connected to tap water pipes for use. This is a huge waste of rainwater and surface water after irrigation, and does not meet the requirements of "economical" garden construction. At the same time, the stored water bodies need to be sedimented, filtered, adsorbed and disinfected to achieve the automatic circulation and replenishment function of water resources so that water resources can be used in different scenarios.

[0004] Chinese patent publication number CN109667312B discloses an automatic circulation replenishment device and method for garden ecological water resources, including a water storage tank, multiple garden water bodies to be balanced, a discharge tank and a circulation device; the circulation device includes a closed transfer tank, and the side wall of the transfer tank is connected to the water storage tank, the garden water body and the discharge tank one by one through multiple pipes; a water level monitoring unit and an electromagnetic valve for controlling the opening or closing of the inside of the pipe are arranged at the end of the pipe; a pressure control unit for controlling the internal air pressure, a controller for controlling the pressure control unit and a communication unit for communicating with the outside world are arranged on the top of the transfer tank; multiple water level monitoring units and multiple electromagnetic valves are electrically connected to the controller and controlled by it. It can be seen that the automatic circulation replenishment device and method for garden ecological water resources have the following problems: the water bodies in the garden are mostly relatively independent, and are directly connected to the tap water pipes for use, which is a huge waste of rainwater and surface water after irrigation, and does not meet the requirements of "economical" garden construction. Because its water storage structure is located below the ground, the water resources stored in the underground water storage structure will always be in a "dead water state" without flow, causing the stored water resources to deteriorate easily. Summary of the invention

[0005] To this end, the present invention provides a water resource recycling management system and method for landscape gardening, so as to overcome the problem in the prior art that most of the water bodies in the gardens are relatively independent and directly connected to the tap water pipes for use, which is a huge waste of rainwater and surface water after irrigation and does not meet the requirements of "economical" garden construction. At the same time, the stored water bodies need to be subjected to operations such as sedimentation, filtration, adsorption and disinfection to realize the automatic circulation and replenishment function of water resources so as to provide water resources for use in different scenarios. Because its water storage structure is located below the ground, the water resources stored in the underground water storage structure will always be in a "dead water state" without flow, resulting in the problem that the stored water resources are very likely to deteriorate.

[0006] To achieve the above object, the present invention provides a water resource recovery management system and method for landscape gardening, comprising:

[0007] The collection unit is used to recycle and filter rainwater and surplus water for garden irrigation to improve the utilization rate of water resources;

[0008] A circulation device, which is connected to the water storage tank and the garden water source, is used to transport water to the irrigation device according to the working status and to transport air to the water storage tank for corrosion prevention;

[0009] A data detection unit, including a rainfall detection sensor, a water tank water level sensor and a water storage timer, is used to confirm the rainfall, the water storage amount of the water tank and the water storage time of the water tank;

[0010] A data analysis unit connected to the data detection unit and the control and regulation unit, used to analyze and process the data information detected by the data detection unit, determine the garden irrigation state according to the rainfall and the irrigation amount required in the current irrigation cycle, and adjust the operation mode of the control and regulation unit according to the water storage amount in the first water storage tank, the water storage amount in the second water storage tank, the deterioration time of the water in the water storage tank, and the irrigation amount required in the current irrigation cycle;

[0011] A control and adjustment unit is connected to the circulation device and the data analysis unit, and is used to adjust the irrigation cycle and the amount of irrigation water according to the garden irrigation status determined by the data analysis unit, and to control the working state of the circulation device according to the operation mode determined by the data analysis unit, and to adjust the water storage time in the first water tank and the oxygen supply rate of the circulation device.

[0012] Furthermore, the water storage tank includes a first water storage tank, which is used as a water storage tank for irrigation and can store water required for irrigation. The first water storage tank is provided with an ozone release unit.

[0013] The second water storage tank is connected to the first water storage tank and the external water use unit, and can store the rainwater collected by the collection unit and the surplus water for garden irrigation, and discharge the stored water to the first water storage tank or the external water use unit according to demand.

[0014] Furthermore, the data detection unit detects the precipitation in the irrigation area and transmits the detection result to the data analysis unit. The data analysis unit compares the precipitation with the irrigation water requirement for a preset single irrigation cycle to determine whether it is necessary to adjust the duration of the current irrigation cycle or the irrigation amount of the current irrigation cycle.

[0015] The data analysis unit compares the precipitation in the irrigation area with the amount of water required for irrigation in a single irrigation cycle, and determines whether the current irrigation cycle needs to be extended based on the determination result;

[0016] If the precipitation in the irrigation area is greater than or equal to the amount of water required for irrigation, the data analysis unit determines that the precipitation covers the amount of water required for irrigation in the current irrigation cycle, and extends the duration of the current irrigation cycle;

[0017] If the precipitation in the irrigation area is less than the amount of water required for irrigation, the data analysis unit determines that the precipitation does not cover the amount of water required for irrigation in the current irrigation cycle, and determines whether to adjust the duration of the current irrigation cycle by analyzing the time when the precipitation occurs;

[0018] If the current precipitation stops within the first irrigation cycle, the current irrigation cycle will be extended;

[0019] If the current precipitation stops within the duration of the second irrigation cycle, the current irrigation cycle will not be extended and the next irrigation amount will be re-determined.

[0020] Furthermore, in the case of extending the irrigation cycle, the data analysis unit compares the water storage time in the first water tank, the extended irrigation time and the water deterioration time to determine whether water needs to be replaced or ozone needs to be added;

[0021] If the water storage time in the first water tank is greater than or equal to the water deterioration time, it is determined that the water in the first water tank has deteriorated, and after the water is replaced, the water storage time starts again;

[0022] If the water storage time in the first water tank is less than the water deterioration time, it is determined that the water in the first water tank has not deteriorated, the water storage time in the first water tank is estimated, and it is determined whether ozone needs to be added.

[0023] Furthermore, if the water stored in the first water storage tank is less than or equal to the water stored in the second water storage tank, all the water stored in the first water storage tank is discharged, and the circulation device inputs the water stored in the second water storage tank into the first water storage tank;

[0024] If the water stored in the first water tank is greater than the water stored in the second water tank, the control and regulation unit adjusts the deterioration time of the water in the first water tank, and the water deterioration time is positively correlated with the proportion of the water stored in the first water tank to the water stored in the first water tank and the water stored in the second water tank;

[0025] Furthermore, if the sum of the water storage time in the first water storage tank and the extended irrigation time is greater than or equal to the water deterioration time, it is determined that the water in the first water storage tank is about to deteriorate within the extended irrigation time, and the circulation device needs to fill ozone into the first water storage tank to delay the deterioration time;

[0026] Among them, if the sum of the water storage time of the first water tank and the extended irrigation cycle is less than the water deterioration time, it is determined that the water stored in the first water tank will not deteriorate during the extended irrigation time, and there is no need to add ozone to delay the deterioration time.

[0027] Furthermore, the control and regulation unit adjusts the oxygen delivery rate of the circulation device according to the adjusted water storage time in the first water storage tank, sets the average oxygen delivery rate of the circulation device to v, and the adjusted oxygen delivery rate is positively correlated with the ratio of the water storage amount in the first water storage tank before and after irrigation and the water storage time of the first water storage tank after mixing;

[0028] Furthermore, in the case where the irrigation cycle is not extended, the water storage in the first water tank, the water storage in the second water tank, the precipitation, and the water required for irrigation in the current irrigation cycle are compared to determine whether the water required for irrigation in the current irrigation cycle can be met;

[0029] If the sum of the water storage in the first water storage tank and the water storage in the second water storage tank is greater than or equal to the difference between the water storage for irrigation and the rainfall, it is determined that the total water storage in the first water storage tank and the second water storage tank can meet the water volume required for irrigation in the current irrigation cycle;

[0030] If the water storage capacity of the first water storage tank is less than the difference between the water storage capacity for irrigation and the rainfall, and is less than or equal to the sum of the water storage capacity of the first water storage tank and the water storage capacity of the second water storage tank, the water storage capacity of the first water storage tank cannot meet the water volume required for irrigation in the current irrigation cycle, and a circulation device is required to transport the water stored in the second water storage tank to the first water storage tank;

[0031] If the sum of the water storage in the first water tank and the water storage in the second water tank is less than the difference between the irrigation water storage and the rainfall, it is determined that the water storage cannot meet the water required for irrigation in the current irrigation cycle, and the circulation device uses garden water for irrigation.

[0032] Furthermore, the collection unit also includes several water troughs opened in low-lying areas, each of which is equipped with a water filter pipe, and the water troughs corresponding to the water filter pipes are filled with a pebble layer and a fine sand layer, and the several water filter pipes are connected to the water storage tank, and the side walls of the water filter pipes are provided with water filter holes, and multiple support rings are evenly sleeved on the outside of the water filter pipes.

[0033] Compared with the prior art, the beneficial effect of the present invention is that by setting up structures such as water troughs, water filter pipes, and water storage tanks, surface water or rainwater can be collected, and at the same time, through operations such as sedimentation, filtration, and adsorption in pebble layers and fine sand layers, the automatic circulation and replenishment function of water resources can be realized, so that water resources can be used in different scenarios.

[0034] Furthermore, the present invention distinguishes between recyclable water resources for garden irrigation and deteriorated water resources according to the water storage time, and selects more effective water resource management and utilization methods accordingly, so that water resource utilization is more in line with actual scenarios, and analyzes and calculates the water storage time in the first water storage tank, and correspondingly adjusts the oxygen delivery rate of the circulation device, further improving the water resource recycling effect.

[0035] Furthermore, the present invention compares the rainfall with the amount of water required for garden irrigation and the amount of stored water to determine whether the rainfall covers the amount of water required for garden irrigation in the current cycle and whether it can meet the garden irrigation needs, and determines whether to increase the garden irrigation cycle or reduce the amount of irrigation water, thereby saving water resources consumed in garden irrigation.

[0036] Furthermore, the present invention allows oxygen to be continuously supplied to the water inside the tank through the circulation device, thereby preventing bacteria from breeding in the water and causing cyanobacteria, which would cause the water to turn green and emit a foul odor, affecting subsequent circulation and replenishment.

[0045] See also Figure 1 As shown, the present invention provides a water resource recycling management system and method for landscape gardening, including a collection unit, which is used to recycle and filter rainwater and surplus water for garden irrigation to improve water resource utilization;

[0046] A circulation device, which is connected to the water storage tank and the garden water source, is used to transport water to the irrigation device and to transport air to the water storage tank for corrosion prevention;

[0047] A data detection unit, including a rainfall detection sensor, a water tank water level sensor and a water storage timer, is used to confirm the rainfall, the water storage amount of the water tank and the water storage time of the water tank;

[0048] A data analysis unit connected to the data detection unit and the control and regulation unit, used to analyze and process the data information detected by the data detection unit, determine the garden irrigation state according to the rainfall and the irrigation amount required in the current irrigation cycle, and adjust the operation mode of the control and regulation unit according to the water storage amount in the first water storage tank, the water storage amount in the second water storage tank, the deterioration time of the water in the water storage tank, and the irrigation amount required in the current irrigation cycle;

[0049] A control and adjustment unit is connected to the circulation device and the data analysis unit, and is used to adjust the irrigation cycle and the amount of irrigation water according to the garden irrigation status determined by the data analysis unit, and to control the working state of the circulation device according to the operation mode determined by the data analysis unit, and to adjust the water storage time in the first water tank and the oxygen supply rate of the circulation device.

[0050] See also Figure 4 As shown, the collection unit also includes a plurality of water troughs 1 opened in low-lying areas, each of which is equipped with a water filter pipe 2, and a pebble layer 3 and a fine sand layer 4 are filled between the water filter pipes 2 and the corresponding water troughs 1. The plurality of water filter pipes 2 are connected to a water storage tank, and the water storage tank includes a first water storage tank, which is used as a water storage tank for irrigation and can store water required for irrigation. The first water storage tank is provided with an ozone release unit,

[0051] The second water storage tank is connected to the first water storage tank and the external water use unit, and can store the rainwater collected by the collection unit and the surplus water for garden irrigation, and discharge the stored water to the first water storage tank or the external water use unit according to demand.

[0052] Specifically, a water filter hole 21 is opened on the side wall of the water filter pipe 2 , and a plurality of support rings 22 are evenly sleeved on the outside of the water filter pipe 2 .

[0053] Assess the total amount of recoverable water resources, including rainfall water resources and irrigation surplus water resources;

[0054] For an irrigation cycle of t1, the precipitation is L and the required irrigation volume is H

[0055] See also Figure 2 As shown in the figure, during any irrigation cycle, if precipitation occurs, the precipitation L falling into the irrigation area is counted, and the precipitation L is compared with the irrigation water required for a single irrigation cycle H.

[0056] If L≥H, it is determined that the precipitation L covers the amount of water required for irrigation in the current irrigation cycle, and the duration of the current irrigation cycle is extended. The extended duration is set to t1', t1'=t1+(LH)÷H×t1×a1, where a1 is the calculation compensation parameter for extending the duration of the irrigation cycle when the precipitation covers the amount of water required for irrigation in the current irrigation cycle; the duration t1' is counted after the current precipitation stops;

[0057] If L<H, it is determined that the precipitation L does not cover the amount of water required for irrigation in the current irrigation cycle. By determining the time when the precipitation occurs, it is determined whether to adjust the duration of the current irrigation cycle.

[0058] The current irrigation cycle duration t1 is divided into a first irrigation cycle duration t11 and a second irrigation cycle duration t12, wherein the first irrigation cycle duration t11 is the first 40% of the current irrigation cycle duration t1;

[0059] If the current precipitation stops within the first irrigation cycle duration t11, the current irrigation cycle duration will be extended.

[0060] If the current precipitation stops within the second irrigation cycle duration t12, the current irrigation cycle duration will not be extended, and the next irrigation amount will be re-determined;

[0061] Specifically, the irrigation cycle is precisely adjusted by dividing the irrigation cycle into the first irrigation cycle and the second irrigation cycle to make the division more accurate. The irrigation method in the current irrigation cycle is determined based on whether the rainfall stops in the first or second irrigation cycle, to avoid the situation where water resources are wasted due to inaccurate cycle adjustment.

[0062] The data analysis unit determines the current irrigation method by comparing the rainfall and the amount of water required for the current irrigation cycle, and extends the irrigation cycle and adjusts the irrigation amount according to the rainfall and the amount of water required for garden irrigation, thereby saving the amount of water resources consumed in garden irrigation.

[0063] Precipitation water resources are estimated by the precipitation in the previous monitoring period. For the supervised garden area, the precipitation in the previous monitoring period T is P;

[0064] The surplus irrigation water resource Q is the irrigation water recovered after the irrigation demand is met.

[0065] Assume that the current recyclable water resources are G, G = P + Q;

[0066] The water from the recyclable water resource is stored in a second water storage tank;

[0067] The water storage capacity in the first water storage tank is R, the water storage time in the first water storage tank is t2, and the water deterioration time is te;

[0068] See also Figure 3 As shown, for the case of extending the irrigation cycle, the water storage time t2 in the first water tank and the extended irrigation time t1' are compared with the water deterioration time te to determine whether water needs to be replaced or ozone is added. The water storage time t2 in the first water tank plus the extended irrigation time t1' is t2'.

[0069] If t2≥te, it is determined that the water in the first water tank has deteriorated and needs to be replaced. The water storage time t2 starts again.

[0070] If R≤G, all the water in the first water tank is discharged, and the circulation device inputs the water G in the second water tank into the first water tank.

[0071] If R>G, the water in the second water tank is mixed with the water in the first water tank, and the water deterioration time te is reset. The adjusted water deterioration time te is set to te', te'=c1×te, c1 is the ratio of the water storage R in the first water tank to the water storage R in the first water tank and the water storage G in the second water tank, c1=R÷(R+G);

[0072] If t2<te, it is determined that the water in the first water tank has not deteriorated and does not need to be replaced. By comparing the sum of the water storage time t2 and the extended irrigation time t1' in the first water tank with the water deterioration time te, it is determined whether ozone needs to be added.

[0073] If t2'≥te, it is judged that the water in the first water tank will deteriorate within the extended irrigation time t1', and the circulation device needs to fill ozone into the first water tank to delay the deterioration time. The ozone filling rate is positively correlated with the water storage capacity R in the first water tank.

[0074] According to the adjusted water deterioration time te', the oxygen delivery rate of the circulation device is adjusted, and the average oxygen delivery rate of the circulation device is set to v. The adjusted oxygen delivery rate v'=te'÷te×b1×v, b1 is the ratio of the water storage in the first water storage tank after irrigation, b1=(R+G+LH)÷R,

[0075] If t2'<te, it is determined that the water in the first water tank will not deteriorate within the extended irrigation time t1', and it is not necessary to add ozone to delay the deterioration time;

[0076] Specifically, if the water storage conditions are uncertain, using spoiled water for garden irrigation will produce odor and damage the growth of garden vegetation, affecting the landscape. The data processing unit distinguishes between recyclable water resources for garden irrigation and spoiled water resources according to the water storage time. The control and regulation unit selects a more effective water resource management and utilization method to make water resource utilization more in line with actual scenarios, and analyzes and calculates the water storage time in the first water tank. The control and regulation unit adjusts the oxygen delivery rate of the circulation device to avoid the growth of bacteria in the water body and the occurrence of cyanobacteria, which makes the water body turn green and emit a foul smell, affecting the subsequent circulation and replenishment use, and further improving the water resource recycling effect.

[0077] In the case where the irrigation cycle is not extended, the data detection unit detects the rainfall L and the number of rainy days t3 in the current cycle t1, and transmits the detection result to the data analysis unit. The data analysis unit calculates the ratio of the rainfall L in the current cycle t1 to the number of rainy days t3, and compares it with the ratio of the irrigation water volume H to the current cycle t1. The ratio of the rainfall L to the number of rainy days t3 is E, E=L÷t3,

[0078] Assume that the amount of water required for irrigation after the current irrigation cycle changes is H', H'=(HL)×k1, k1 is the calculation parameter of the amount of water required for irrigation after the current irrigation cycle changes H',

[0079] If E≥H÷t1, the calculation parameter k1≥1 for the irrigation water volume H' after the current irrigation cycle changes.

[0080] If E<H÷t1, the calculation parameter k1 of the irrigation water volume H' required after the current irrigation cycle changes is <1;

[0081] Specifically, the data analysis unit determines the impact of rainwater transpiration and rainfall loss on the amount of water required for irrigation at different ratios based on the ratio of rainfall to rainfall days in the current cycle. The larger the ratio, the greater the difference between rainfall and rainfall days, indicating that more water is transpired and lost. The data analysis unit increases the difference between the amount of water required for irrigation and the rainfall through the corresponding control circulation device to ensure that the garden irrigation needs are met after the irrigation cycle changes, thereby further improving the accuracy of water resource recycling in this system.

[0082] Furthermore, the water storage R in the first water tank and the water storage G in the second water tank are compared with the precipitation L and the irrigation water volume H' after the current irrigation cycle changes to determine whether the irrigation water volume requirement of the current irrigation cycle can be met. Suppose the sum of the water storage R in the first water tank and the water storage G in the second water tank is M,

[0083] If M≥H', it is judged that the total water storage capacity of the first water tank and the second water tank can meet the water volume required for irrigation in the current irrigation cycle.

[0084] If R<H'≤M, the water storage capacity of the first water storage tank cannot meet the water volume required for irrigation in the current irrigation cycle, and a circulation device is required to transport the water stored in the second water storage tank to the first water storage tank.

[0085] If M<H', it is judged that the water storage capacity cannot meet the water required for irrigation in the current irrigation cycle, and the circulation device uses garden water for irrigation;

[0086] Specifically, if the data analysis unit does not compare the water storage in the first water tank, the water storage in the second water tank, the precipitation, and the water required for irrigation in the current irrigation cycle, when the garden is irrigated, the control and regulation system cannot determine whether the water storage in the water tank can meet the garden irrigation water demand in the current irrigation cycle, which may cause incomplete garden irrigation and affect the growth of landscape vegetation. The data analysis unit compares the water storage in the first water tank, the water storage in the second water tank, the precipitation, and the water required for irrigation in the current irrigation cycle, which reduces the possibility of incomplete garden irrigation and improves the reliability of the circulation device in the current irrigation cycle.

The water resource recovery and management system for landscape gardening according to claim 1, characterized in that: In the case where the irrigation cycle is not extended, the water storage in the first water storage tank, the water storage in the second water storage tank, the precipitation, and the water required for irrigation in the current irrigation cycle are compared to determine whether the water required for irrigation in the current irrigation cycle can be met; If the sum of the water storage in the first water storage tank and the water storage in the second water storage tank is greater than or equal to the difference between the water storage for irrigation and the rainfall, it is determined that the total water storage in the first water storage tank and the second water storage tank can meet the water volume required for irrigation in the current irrigation cycle; If the water storage capacity of the first water storage tank is less than the difference between the water storage capacity for irrigation and the rainfall, and is less than or equal to the sum of the water storage capacity of the first water storage tank and the water storage capacity of the second water storage tank, the water storage capacity of the first water storage tank cannot meet the water volume required for irrigation in the current irrigation cycle, and a circulation device is required to transport the water stored in the second water storage tank to the first water storage tank; If the sum of the water storage in the first water tank and the water storage in the second water tank is less than the difference between the irrigation water storage and the rainfall, it is determined that the water storage cannot meet the water required for irrigation in the current irrigation cycle, and the circulation device uses garden water for irrigation.

8. The water resource recovery and management system for landscape gardening according to claim 1, characterized in that: The collection unit also includes several water troughs opened in low-lying areas, each of which is equipped with a water filter pipe. Pebble layers and fine sand layers are filled between the corresponding water troughs of the water filter pipes. Several water filter pipes are connected to a water storage tank. Water filter holes are opened on the side walls of the water filter pipes, and multiple support rings are evenly sleeved on the outside of the water filter pipes.

9. A water resource recovery management method for landscape gardening, applied to the water resource recovery management system for landscape gardening as claimed in any one of claims 1 to 8, characterized in that: include, Count the precipitation in the current irrigation cycle and compare it with the preset irrigation water consumption, and determine whether to adjust the interval length of the irrigation cycle or the irrigation water consumption according to the comparison result; Compare the water storage time in the first water storage tank with the water deterioration time, and determine whether it is necessary to change the water or add ozone according to the comparison result; After the irrigation cycle is extended, the water storage time in the first water tank is estimated, and compared with the water deterioration time, and it is determined whether it is necessary to mix the water in the second water tank with the water in the first water tank or to add ozone according to the comparison result; After the water in the second water tank is mixed with the water in the first water tank, the proportion of the water in the first water tank before mixing to the water after mixing is calculated, and the storage time of the water in the first water tank is adjusted according to the ratio; adjusting the oxygen delivery rate of the circulation device according to the adjusted water storage time in the first water storage tank; The sum of the water storage in the first water tank and the water storage in the second water tank is calculated, and compared with the difference between the water storage for irrigation and the rainfall. Based on the comparison result, it is determined whether to mix the water stored in the water tanks or use garden water for irrigation.
