For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] In water transmission and distribution and water treatment processes, there are often multiple groups of parallel operations. In order to ensure the uniformity of water distribution between the parallel water transmission pipes and water treatment structures, a water distribution facility is generally set up, such as a water distribution well, a water distribution valve, etc.

[0040] The hydraulic water distribution method not only has simple structure of water distribution facilities and convenient operation and maintenance, but also can automatically and evenly distribute water without human operation. Hydraulic water distribution includes symmetrical water distribution, weir-type water distribution wells and asymmetrical water distribution. As the most common water distribution facility, the weir-type water distribution well generally consists of an inlet well, an overflow weir and mutually separated outlet wells. The weir-type water distribution well distributes water based on the principle of equal head and equal flow on the weir of overflow weirs of equal width. The weir-type water distribution well has many advantages, such as uniform water distribution, the uniformity of water distribution is not affected by the condition of the pipes (outlet pipes) leading to the structure, and it can be arranged symmetrically or asymmetrically.

[0041] However, the water inlet head of the weir-type water distribution well has a great influence on the overflow of the weir top.

[0042] In order to solve the above problems, an embodiment of the present application provides a steady-flow water distribution well. The solution provided by the embodiment of the present application will be described in detail below in conjunction with the drawings in the specification.

[0043] Figure 1 is a schematic diagram of a steady-flow water distribution well provided in the first embodiment of the present application; Figure 2 It is a schematic diagram of a steady flow water distribution well provided in the second embodiment of the present application.

[0044] The embodiment of the present application provides a steady flow water distribution well, including a water inlet well 100, a water inlet well 200, a water inlet pipe 300, a steady flow hole and a water outlet pipe 500. The water inlet well 200 is arranged on the side of the water inlet well 100, and the water inlet well 200 is connected with the water inlet well 100 through the steady flow hole. The water inlet well 100 is connected with the water inlet pipe 300, and the water flows into the water inlet well 100 through the water inlet pipe 300. The water inlet well 200 is connected with the water outlet pipe 500, and the water after the steady flow water distribution is completed is discharged through the water outlet pipe 500.

[0045] The steady flow water distribution well can be made into a circular or rectangular shape according to actual needs. According to the arrangement of the water inlet well 100 and the water inlet well 200, the steady flow water distribution well can be configured as a single-sided type or a double-sided type. Figure 1 As shown, the steady flow water distribution well provided in this embodiment is a single-side type, including a water inlet well 100 and three water inlet wells 200. The three water inlet wells 200 are located on the same side of the water inlet well 100 and are connected to the water inlet well 100 respectively.

[0046] Reference Figure 2 As shown, the steady-flow water distribution well provided in this embodiment is of a double-sided type, specifically including a water inlet well 100 and two water inlet wells 200, the two water inlet wells 200 are respectively located on both sides of the water inlet well 100, and are respectively connected to the water inlet well 100. The size of the water inlet well 200 arranged on both sides (the size of a well on one side) is consistent with the water inlet well 100, and the size of the water inlet well 200 arranged on one side (the overall size of all the water inlet wells 200 combined) is consistent with the water inlet well 100.

[0047] The double-sided steady-flow water distribution well will be described below with reference to the accompanying drawings.

[0048] Figure 3 yes Figure 2 Cross-sectional view of a steady flow distribution well.

[0049] Reference Figure 2 and Figure 3As shown, the steady flow water distribution well includes an inlet well 100, an inlet well 200, an inlet pipe 300, a steady flow hole and an outlet pipe 500. Among them, an overflow weir 600 is vertically arranged in the inlet well 200, the height of the overflow weir 600 is less than the depth of the inlet well 200 of the inlet well 100, and the overflow weir 600 divides the inlet well 200 into a first space 210 and a second space 220, and the first space 210 and the second space 220 are connected through the space above the overflow weir 600; the inlet pipe 300 is connected to the inlet well 100, and the inlet well 100 is connected to the first space 210 through the steady flow hole; the outlet pipe 500 is connected to the second space 220. The water level difference on both sides of the steady flow hole is the local head loss generated during the submerged outflow process between the inlet well 100 and the inlet well 200.

[0050] Exemplarily, an overflow weir 600 is provided at a position 1 / 3 of the length of the overflow hole in the length direction of the water inlet well 200. The water head height on the overflow weir 600 can be calculated and determined according to the distribution flow rate according to the rectangular thin-walled weir. Considering the 0.35m drop of the overflow weir 600 in the water inlet well 200, that is, the water level difference of 0.35m on both sides of the overflow weir 600 in the water inlet well 200, it should be ensured that the water head of the pressure measuring tube at any point of the outlet pipe 500 is less than the water level on the outlet side of the overflow weir 600. A water distribution well outlet pipe 500 and a water discharge pipe 900 are provided on the low water level side (second space 220) of the water inlet well 200. The diameter of the outlet pipe 500 is calculated and determined according to the designed water distribution flow rate at a flow rate of 0.8m / s. The diameter of the water discharge pipe 900 is one level smaller than the diameter of the outlet pipe 500, and a water discharge valve 910 is provided.

[0051] Specifically, the water inlet pipe 300 extends from the bottom of the water inlet well 100 into the water inlet well 100, so that the water surface rises slowly from the bottom of the water inlet well 100. The water outlet pipe 500 is connected to the second space 220 inside the water inlet well 200 from the bottom of the water inlet well 200. In addition, the steady flow water distribution well also includes an inlet control valve 310 and an outlet control valve 510. The inlet control valve 310 is arranged on the inlet pipe 300, and the inlet control valve 310 is used to control the opening and closing of the inlet pipe 300. The outlet control valve 510 is arranged on the outlet pipe 500, and the outlet control valve 510 is used to control the opening and closing of the outlet pipe 500.

[0052] Water flows into the water inlet well 100 through the water inlet pipe 300, and then enters the first space 210 through the well steady flow port 400. As the water flows continuously into the first space 210, the water in the first space 210 overflows the overflow weir 600 into the second space 220, and then is discharged through the water outlet pipe 500. It can be understood that the water level difference between the water inlet well 100 and the water inlet well 200 is used as the stabilizing head, and the water volume is initially distributed through the steady flow hole, thereby eliminating the influence of the water head on the overflow weir 600.

[0053] The water level difference between the inlet well 100 and the inlet well 200 is called the steady pressure head. The recommended value of the steady pressure head is 0.3m, which can be increased or decreased appropriately according to the water distribution accuracy requirements. The steady pressure head is numerically equal to the local head loss at the place where water flows through the steady flow hole.

[0054] The local head loss at the steady flow hole includes the loss caused by the contraction of the water flow at the inlet and the loss caused by the diffusion of the water flow at the outlet.

[0055] The local head loss coefficient of water flow contraction at the inlet of the steady flow hole is 0.5, the local head loss coefficient of water flow diffusion at the outlet is 1.0, and the comprehensive resistance coefficient of the steady flow hole is 1.5.

[0056] According to the steady pressure head, the comprehensive resistance coefficient, and the designed distribution flow (the flow of a single water inlet well 200), the size of the steady flow hole can be determined, and the plane size of the steady flow hole can be determined according to the aspect ratio of 2:1-4:1.

[0057] An overflow weir 600 is provided in the water inlet well 200 at a position 1 / 3 of the length from the overflow hole in the length direction. The water head height above the weir can be calculated and determined according to the distributed flow rate based on the rectangular thin-walled weir.

[0058] For example, the flow rate of the water inlet pipe 300 is generally controlled at about 1 m / s. The flow rate can determine the diameter of the water inlet pipe 300 according to the designed water distribution flow rate.

[0059] The plane size of the water inlet well 100 is calculated and determined based on the falling flow rate of water at 0.1m / s, that is, the flow cross-sectional area of ​​the water inlet well 100 is not less than 10 times the cross-sectional area of ​​the water inlet pipe 300. In addition, in order to facilitate maintenance, the size of the water inlet well 100 and the water inlet well 200 should not be less than 800mm.

[0060] The water inlet pipe 300 is vertically connected from the center of the bottom of the water inlet well 100, and the height of the water inlet pipe 300 extending from the bottom of the well is not less than 0.80m.

[0061] The flow rate of the water inlet pipe 300 is 1m / s, and the "recovery head" height at the outlet of the water inlet pipe 300 in the water inlet well 100 is about 0.05m, that is, the actual water depth in the water inlet well 100 is not less than 0.85m. Considering the 0.3m safety height, the depth of the water inlet well 100 is not less than 1.15m.

[0062] In addition, continue to refer to Figure 2 As shown, the steady-flow water distribution well also includes a steady-flow regulating component 700 , an overflow pipe 800 and a plurality of drain pipes 900 .

[0063] Figure 4 yes Figure 2 A first schematic diagram of a steady flow outlet 400 of a steady flow water distribution well; Figure 5 yes Figure 2A second schematic diagram of the steady flow outlet 400 of the steady flow water distribution well.

[0064] Reference Figure 2 , Figure 4 and Figure 5 The flow regulating assembly 700 includes a fixing member 710 and an adjusting control 720. The fixing member 710 is fixedly arranged on one side of the flow regulating hole. The adjusting control 720 is arranged on the fixing member 710. The adjusting control 720 is used to adjust the size of the flow regulating hole.

[0065] Exemplarily, the fixing member 710 is configured as a fixing bolt, and the control unit 720 is configured as a flow-stabilizing regulating steel plate. The fixing bolt is fixedly arranged on one side of the flow-stabilizing hole. The flow-stabilizing regulating steel plate is provided with an oblong hole, and the flow-stabilizing regulating steel plate is slidably fitted on the fixing bolt through the oblong hole. The flow-stabilizing regulating steel plate selectively moves to adjust the size of the flow-stabilizing hole, thereby controlling the size of the water flow entering the first space 210 from the water inlet well 100, and regulating the pressure-stabilizing water head.

[0066] Continue to refer to Figure 3 As shown, the overflow pipe 800 is arranged perpendicular to the bottom of the water inlet well 100, and one end of the overflow pipe 800 extends from the bottom of the water inlet well 100 to the water inlet well 100. The length of the end of the overflow pipe 800 located in the water inlet well 100 from the bottom of the water inlet well 100 is greater than the height of the overflow weir 600 and less than the depth of the water inlet well 100, thereby ensuring that the water flow can overflow the overflow weir 600 and cannot overflow from the water inlet well 100. In other words, the height of the overflow pipe extending into the water inlet well 100 is greater than the height of the overflow weir 600. In addition, an overflow bell mouth 810 is provided at one end of the overflow pipe 800 located in the water inlet well 100, thereby facilitating the rapid overflow of water from the overflow pipe 800. Exemplarily, the caliber of the overflow bell mouth 810 is 1.5 times the diameter of the overflow pipe 800, and the top of the bell mouth is horizontally installed at a position 50 mm above the designed water surface of the water inlet well 100, that is, 0.90 m above the bottom of the water inlet well 100.

[0067] In addition, the diameter of the water inlet well 200 is greater than or equal to the diameter of the water inlet pipe 300 .

[0068] There are multiple drain pipes 900, and the multiple drain pipes 900 are respectively connected to the water inlet well 100 or the second space 220. At least one drain pipe 900 is set in the water inlet well 100, the first space 210 and the second space 220 to facilitate drainage and maintenance. A drain valve 910 is set on the drain pipe 900, and the drain valve 910 is used to control the opening and closing of the drain pipe 900, thereby controlling the outflow of water. The mouth of the drain pipe 900 is flush with the bottom of the well, and the pipe diameter is one level smaller than the designed diameter of the water inlet pipe 300.

[0069] Figure 6 yes Figure 2A first schematic diagram of the overflow weir 600 of the steady flow water distribution well; Figure 7 yes Figure 6 The structural schematic diagram of the overflow weir adjustment steel plate 610 in the steady flow water distribution well also includes an overflow weir adjustment steel plate 610, which is arranged on the top of the overflow weir 600, so as to facilitate the adjustment of the height of the overflow weir 600. Ensure the uniformity of water distribution. Exemplarily, the overflow weir adjustment steel plate 610 is slidably arranged on the overflow weir 600, which can slide in the vertical direction to adjust the total height of the overflow weir 600 and the overflow weir adjustment steel plate 610.

[0070] The solution of the present application will be described in detail below in conjunction with a specific embodiment.

[0071] A water treatment process is designed to process 20,000 m3 of water. 3 / d, divided into 2 groups and operated in parallel. Raw water enters the water inlet well 100 vertically from the bottom of the water inlet well 100 through the water inlet pipe 300, and the kinetic energy is converted into potential energy in the process of the flow velocity decreasing in the water inlet well 100.

[0072] The water inlet pipe 300 adopts a DN500 welded steel pipe. The flow rate of the water inlet pipe 300 is calibrated to be 1.1m / s, generating a "recovery head" of 0.06m.

[0073] The water inlet pipe 300 is provided with a water inlet control valve 310 which can control the water inlet flow rate.

[0074] The outlet of the water inlet pipe 300 extends 0.84m from the bottom of the water inlet well 100, plus the "recovery head" height of 0.06m. The water depth in the water inlet well 10010 is 0.90m. Considering the safety height of 0.3m, the effective depth of the water inlet well 100 is 1.20m.

[0075] According to the water flow rate of 0.1m / s, the flow cross-sectional area of ​​the water inlet well 100 is determined to be at least 2.0m2, and the net size of the water inlet well 100 is: 1.5m×1.5m×1.2m.

[0076] A DN600 (one level larger than the diameter of the water inlet pipe 300) overflow pipe 800 is provided in one corner of the water inlet well 100, a Φ900 overflow bell mouth 810 is provided at the upper end of the overflow pipe 800, the overflow pipe 800 is vertically installed in the water inlet well 100, and no valve is installed on the overflow pipe 800.

[0077] A DN450 (one level smaller than the diameter of the water inlet pipe 300) drain pipe 900 is arranged at the other corner of the water inlet well 100, and a drain valve 910 is installed on the drain pipe 900 for use in maintenance and draining.

[0078] The pressure stabilizing head is 0.3m, that is, the head loss of water flowing through the stabilizing hole is 0.3m.

[0079] It is known that the local head loss of the steady flow hole is 0.3m and the comprehensive resistance coefficient is 1.5, so the through-hole flow velocity at the steady flow hole 80 can be calculated to be 2.5m / s.

[0080] According to the double-sided operation, the distribution flow of a single water inlet well 200 is 10,000 m 3 / d, the area of ​​the steady flow hole is 0.05m 2 The size of the steady flow hole is B×H=1.0m×0.5m.

[0081] When the actual water distribution requirements are high, the steady flow head can be increased by reducing the area of ​​the steady flow hole, so that the steady flow head is greater than the default value of 0.3m. Similarly, when the water distribution requirements are low, the area of ​​the steady flow hole can be increased to reduce the steady flow head, so as to achieve the purpose of reducing the water distribution head loss.

[0082] The area size of the flow stabilizing hole can be achieved by adjusting the flow stabilizing regulating component 700 .

[0083] Known distribution flow 10,000 m 3 / d, according to the thin-wall weir formula, the water head height above the overflow weir 600 can be determined to be 0.02m.

[0084] The water depth in the water inlet well 100 is 0.9m. After deducting the steady flow head of 0.3m and the head above the weir of 0.02m, it can be determined that the height of the top of the overflow weir 600 relative to the bottom of the water inlet well 200 is 0.58m.

[0085] An overflow weir adjustment steel plate 610 is installed on the top of the overflow weir 600. The height of the overflow weir 600 steel plate can be adjusted up and down by fixing bolts to adjust the height and levelness of the overflow weir 600 top.

[0086] Considering that the height of the water drop in the overflow weir 600 is 0.35 m, the water depth on the outlet side of the water inlet well 200 is 0.25 m, that is, the water head of the pressure measuring tube of the outlet pipe 500 is less than 0.25 m.

[0087] The water outflow from the distribution well is at a flow rate of 0.8m / s, and a DN450 outlet pipe 500 can meet the requirement.

[0088] The diameter of the drain pipe 900 in the water inlet well 200 is determined to be one level smaller than the outlet pipe 50040. A DN400 drain pipe 900 with a drain valve 910 can meet the drain maintenance requirements.

[0089] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application.
