Background
In the large tracts of land circulating water system (class swimming pool, waterscape etc.) that has equalizing basin, because receive traditional ball-cock assembly and should not submerge totally for a long time in the material characteristic influence of aquatic installation operation, the interval setting between automatic water supply working water level in the equalizing basin and the overflow position is about 150mm-200mm according to national standard and design custom, nevertheless because the influence of reasons such as place and cost, the plane area of equalizing basin can not be very big, and it is less to holding the regulation volume between the overflow position to its water supply level. However, to ensure proper circulation of these large circulating bodies of water, the amount of water that needs to be net lifted upstream from the equalization tank can be much greater than the conditioning volume of the equalization tank. Therefore, during the outage period of each operation period (each time, every day, and the like) of the facility systems, a large amount of upstream pool backwater can occur, the overflow position of the equalization pool is hidden and overflowed away, the upstream pool backwater cannot be reused, and the water leakage mode is hidden and difficult to find, so that a large amount of water resources are wasted. In addition, because the calculation of parameters such as the relevant size and elevation of the equalization tank is complex and tedious, manual calculation is very difficult and error is easy to occur, and the appropriate and economic size is difficult to adjust timely according to the actual project requirements.
Therefore, the design method for rapidly calculating the circulating water return amount of each stage of the upstream water pool, determining the size and the internal key water level control line elevation of the equalizing pool, selecting proper equipment and installing the equipment in a novel combination mode so as to save capital construction investment and water resources is a problem to be solved urgently by researchers.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Implementation 1: the structure of the equalizing basin calculation summary table and the process flow of the circulating pond system (swimming pool) is shown in the figure 1-2.
The method comprises the following specific implementation steps:
when the circulating water pond system stops operating, the water level in the pond 1 is the static water level 121, no water exists in the pond overflow channel 132, no water exists in the pond surface layer gravity water return pipe 2, the water level in the equalizing pond 3 is the overflow level 312, and all the pipes in the equalizing pond bottom gravity water return pipe 4, the equipment room 5, the water pump 51, the filter 52, the pond water inlet pipe 112 and the like are filled with water. When the system is in dynamic balance, the water level in the pool 1 will rise to the pool working water level 122, and the rising volume 123 can be calculated by the table 1 and formula of the balance pool calculation summary table in fig. 4; at this time, water is in the pool overflow gutter 132, and the volume of accumulated water can be calculated by the formula and table 2 of the balance pool calculation summary table in fig. 4; the gravity water return pipe 2 of the pool surface layer is filled with water, and the volume in the pipe is calculated by a formula and a table 3 of a calculation summary table of the equalizing pool in fig. 4; the water level in the equalizing tank 3 is reduced to 311, the reduction volume is 313, and it is easy to know from a schematic diagram that the reduced water amount in the equalizing tank is equal to the increased water amount of each relevant part of the external water tank, so that the following formula is obtained:
volume 313(V) is volume 123(V1) + volume 132(V2) + volume of return pipe 2 (V3) a.
S Area of equalizing pool H Descending height of water level of equalizing tank ＝V Reduction of equalization tank volume ＝V Water volume increase of upstream water pool at different levels ＝(V1+V2+V3) Balance pool calculation table summary table data
From the above extrapolation, we find:
the key control water level line (311) elevation is equal to the overflow water level (312) elevation-H Descending height of water level of equalizing tank
Then, according to fig. 2, the opening/closing control line of the full-automatic water level control valve 322 is installed to overlap the water level line 311. The installation main points are as follows: firstly, the full-automatic water level control valve 322 should be made of plastic and other related water-resistant materials, and can normally and effectively act after being submerged and soaked in water for a long time; secondly, a starting and closing control line of the full-automatic water level control valve 322 is superposed with the water level line 311, when the actual water level is higher than the water level line 311, the control valve is closed, and when the actual water level is lower than the water level line 311, the control valve is opened, and the equalizing tank is used for supplementing water; thirdly, the water replenishing outlet 321 of the equalizing tank must be arranged above the overflow level 312 by not less than 50-100mm, so as to know the underwater working state of the control valve 322 by observing the water flow state of the outlet; fourthly, the control valve 323 is also arranged above the overflow water level 312 and is not less than 50-100mm, so that the operation is convenient and the damage caused by long-term immersion in water is avoided; fifthly, water is supplemented before the primary operation of the equalizing tank 3, the water level needs to be supplemented to the overflow level 312, otherwise the circulating water system cannot work normally.
It is easy to see from the formula: when the volume is 313(V) < volume 123(V1) + volume 132(V2) + volume of water return pipe 2 (V3), the water level of equalizing tank 3 will continue to drop after dropping to the water replenishing working water level 311, full-automatic water level control valve 322 opens water replenishing until the whole circulating water tank system enters dynamic balance, and full-automatic water level control valve 322 closes after water replenishing to water level 311. Thus, when the system is periodically shut down, the upstream sump is drawn from the equalization tank to remove the added volume, and is returned to equalization tank 3 entirely. The more the water amount is supplemented from the full-automatic water level control valve 322, the more the water amount is overflowed from the overflow port 331 in the process of completing the water return of the upstream water pool, thereby forming hidden water leakage, the more the volume 313 is smaller than the sum of the external water demand, the larger the water supplementing amount of the full-automatic water level control valve 322 is during the period of forming dynamic balance when the system starts to operate, thereby when the system cycle stops, the larger the water amount is overflowed from the overflow port 331, the day and month are accumulated, and the loss of water resources can be serious. Therefore, in principle, no leakage occurs when volume 313(V) ≧ volume 123(V1) + volume 132(V2) + return pipe 2 volume (V3).
The elevation of the equalization tank bottom is calculated by the equations and tables 5, 6, 7, 8 of the equalization tank calculation summary table of figure 4,
V volume of basic water level of equalizing tank ＝(V4+V5+V6) Balance pool calculation table summary table data ＝S Equalizing pool area H Height of basic water level of equalizing tank
V4＝(S1 Area of pool +......+Sn Area of pool )w Loss height of evaporation
V5＝V Filter backwash volume ＝Q Flow rate of water pump t Time of pumping V6＝S Minimum guaranteed water absorption depth of H water pump with balanced pool area
The tank bottom elevation of the equalizing tank is equal to the elevation-H of a key control water level line (311) Height of water level of foundation of equalizing tank
It is easy to know that the final effective water storage volume of the equalizing tank is:
V general assembly ＝V1+V2+V3+V4+V5+V6
When the formula:
volume 313(V) is not less than 123(V1) + 132(V2) + 2 (V3)
When equal numbers are taken, the balance tank achieves the minimum effective water storage volume, and the lowest possible cost and the most economical cost can be realized under the same construction process and materials.
Through the table 8 in the equalizing tank calculation summary table in fig. 4, the length and width of the inner wall of the equalizing tank can be adjusted at will, and the required parameters such as the control elevation of the key water line and the height of the tank bottom corresponding to the parameters can be obtained quickly, so that the size of the equalizing tank more meeting the requirements of actual project landform can be found quickly, and the cost performance is higher.
Example 2: the example describes a process flow diagram of a circulating pond system (waterscape), and the structure of the process flow diagram is shown in figure 3.
The method comprises the following specific implementation steps:
when the circulating water pond system stops operating, the water level in the water pond 1 is a static water level 121, no water is arranged on the water falling weir 133, the water level in the equalizing pond 3 is an overflow water level 312, the water pump 51 is directly submerged in the equalizing pond 3, and the water inlet pipe 112 of the water pond is full of water. When the system operates to dynamic balance, the water level in the pool 1 is raised to the working water level 122 of the pool, the rising volume 123 can be calculated, and the volume can be calculated when water exists on the water falling weir 133; the water level in the equalizing tank 3 is reduced to 311, the reduction volume is 313, and the figure shows that
Volume 313(V) ≈ volume 123(V1) + drop weir 133 flowing water volume ≈ volume 123(V1) (1+ S123/S133)
Therefore, the key control water level line 311 of the equalizing tank can be automatically calculated by substituting the existing conditions into the equalizing tank calculation summary table in fig. 4, and then the opening and closing control line of the full-automatic water level control valve 322 is installed to be overlapped with the water level line 311, and the installation requirement is the same as that of the embodiment 1. It should be noted that the equalizing basin in the circulating water basin system (waterscape) has various shapes and styles, such as a ditch, a pit, a pool and the like, there may be more than 1 upstream water basin, there may be no overflow ditch 132, return pipe 2, return pipe 4 and the like connected with the equalizing basin, and the circulating water flow directly enters the equalizing basin by other means, so that there is no facility link and the volume of water is 0 during the summary calculation. The equalizing tank is similar in shape, and a water pump is generally directly submerged in the equalizing tank by adopting a submersible pump. The calculation of the elevation of the bottom of the equalization tank and the estimation of the final size of the equalization tank are the same as those in example 1.
