[0030] By providing an adjustable forebay of a pumping station in the embodiments of this application, the problem of how to enable the pumping station to meet the requirements of different drainage tasks is solved, and the use of the pumping station in different drainage tasks is realized.
[0031] The technical solutions in the embodiments of this application to solve the above technical problems are generally as follows:
[0032] The construction task of the pumping station 12 is to pump and drain the flood water in the lake area and the urban waterlogging. The drainage levels for flood drainage and waterlogging drainage differ by 1 m. By arranging the partition structure 20 and the connecting structure 21 in the forebay, the pumping station 12 is enabled to have both the functions of flood drainage and waterlogging drainage or a single flood drainage or waterlogging drainage function, realizing the joint dispatching of the pumping station 12, improving the operation efficiency of the pumping station, and facilitating centralized operation management.
[0033] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.
[0034] As Figures 1-5 shown, an adjustable forebay of a pumping station includes an inlet structure 11, a pumping station 12 and two retaining walls 10. The inlet structure 11, the pumping station 12 and the two retaining walls 10 enclose the forebay of the pumping station;
[0035] The forebay of the pumping station is partitioned into two adjacent forebays by a partition structure 20;
[0036] A plurality of inlet sluices 111 are arranged on the inlet structure 11, and the plurality of inlet sluices 111 control the water inlet of the corresponding forebay;
[0037] A connecting structure 21 is arranged on the partition structure 20, and a connecting sluice 22 is installed on the connecting structure 21. The connecting sluice 22 controls the flow of water in the two forebays.
[0038] By setting up the partition wall structure 20, the forebay of the pumping station is divided into two forebays, and a connection structure 21 is arranged on the partition wall structure 20 to control the flow or blockage of the water flow in the two forebays according to different drainage tasks, solving the problems in the prior art that the forebays are either independent or can be combined into one, the construction, land occupation and management costs of independent pumping stations are high, and when combined pumping stations are built, it is necessary to consider the peak-shifted incoming water in different drainage areas, make advance predictions, the entire scheduling process is complex to operate, and the energy consumption of the unit operation is relatively high.
[0039] Specifically, according to the flow demand of the pumping station, a plurality of connection structures 21 are arranged, and according to specific requirements, a plurality of partition wall structures 20 can be arranged.
[0040] As Figures 3-4 shown, the connection structure 21 is arranged in an open shape. The connection structure 21 includes an empty box 211 and a gate orifice 212. The empty box 211 and the gate orifice 212 are connected through a lintel 214. The lintel 214 is designed in an inverted frustum shape. A ladder 23 is installed inside the empty box 211. A gate 222 is installed on the connection sluice 22. The gate 222 is installed on the connection sluice 22 through a screw rod 221. The gate 222 is slidably connected to the inner side wall of the connection structure 21 through a gate groove 215. A flow port 213 is opened on the connection structure 21, and the flow port 213 is connected to the gate orifice 212.
[0041] During operation, the hoist controls the screw rod 221 to drive the opening or closing operation of the gate 222;
[0042] By arranging the connection structure 21 in the form of an empty box 211 and a gate orifice 212, and arranging a ladder 23 inside the empty box 211, maintenance personnel can enter the empty box 211 through the ladder 23, which is convenient for the maintenance of the connection sluice 22.
[0043] The connection sluice 22 is detachably connected to the connection structure 21. Specifically, it can be connected by plugging or bolt fixing. By arranging the connection sluice 22 to be detachable from the connection structure 21, it is convenient for the subsequent replacement and maintenance of the connection sluice 22.
[0044] The lintel 214 is connected to the gate groove 215 in a through manner. The lintel 214 is in an inverted frustum shape. The gate 222 is slidably connected to the connection structure 21 through a pulley 223.
[0045] By arranging the lintel 214 in an inverted frustum shape, it is convenient for the pulley 223 on the side of the gate 222 to enter the gate groove 215 through the lintel 214, which is convenient for the sliding of the gate 222 on the inner side wall of the connection structure 21.
[0046] As Figure 5 shown, the partition wall structure 20 is a reinforced concrete "I"-shaped structure, and the concrete strength grade is not less than C25.
[0047] The layout length of the partition wall structure 20 is determined according to the usage requirements of the forebay. To prevent and reduce deformation or cracks caused by factors such as uneven settlement of soft foundation and temperature change, the segmented length of the partition wall structure 20 is 10 - 15 m. A permanent joint is provided between adjacent segments, with a joint width of 20 mm. The joint is filled with polyethylene closed-cell board, and horizontal and vertical water-stop structures are provided. The water-stop structure is rubber water-stop or copper sheet water-stop.
[0048] During operation, the construction task of the pumping station 12 is to drain the flood water in the lake area and urban waterlogging. The drainage levels for flood drainage and waterlogging drainage differ by 1 m. By setting the partition wall structure 20 and the connection structure 21 in the forebay, the pumping station 12 can simultaneously have the functions of flood drainage and waterlogging drainage or a single flood drainage or waterlogging drainage function.
[0049] According to the actual requirements of the waterlogging drainage task, the connection sluice 22 can be selected to be opened or closed. When the connection sluice 22 is closed, the two forebays are used independently, and the water flows into the corresponding forebay through the corresponding intake sluice 111 provided on the intake structure 11.
[0050] When the connection sluice 22 is opened, the independently separated forebays are used as a whole, and water exchange is formed between the two separated forebays to balance the water level difference, solving the problem that when the pumping station performs the waterlogging drainage task for different drainage areas simultaneously, due to the need to select the pump model according to the low water level for waterlogging drainage, the energy consumption of the pump is wasted.
[0051] In summary, compared with the prior art, the following beneficial effects are achieved:
[0052] 1. By setting the partition wall structure 20, the forebay of the pumping station is divided into two forebays, and a connection structure 21 is set on the partition wall structure 20 to control the flow or blockage of water in the two forebays according to different waterlogging drainage tasks, solving the problems in the prior art that through the connection structure, the forebays can be independent or combined into one, the construction, land occupation, and management costs of independent pumping stations are high, and when combined pumping stations are built, it is necessary to consider the staggered incoming water in different drainage areas and make advance predictions, and the entire scheduling process is complex in operation, and the energy consumption of the unit operation is relatively high.
[0053] 2. By setting the connection structure 21 in the form of an empty box 211 and a gate orifice 212, and a ladder 23 is provided inside the empty box 211, it is convenient for the maintenance of the connection sluice 22.
[0054] 3. By setting the partition wall structure 20 in segments, and the segmented length of the partition wall structure 20 is 10 - 15 m, a permanent joint is provided between adjacent segments, with a joint width of 20 mm. The joint is filled with polyethylene closed-cell board, and horizontal and vertical water-stop structures are provided. The water-stop structure is rubber water-stop or copper sheet water-stop, which can effectively prevent and reduce the problems of deformation or cracks caused by factors such as uneven settlement of soft foundation and temperature change.
