Description

Technical Field

[0001] This utility model relates to the field of urban water supply system technology, and in particular to a modified secondary pump station structure. Background Technology

[0002] Urban water supply systems are a fundamental infrastructure of urban life, providing safe and reliable drinking water for city residents. Secondary pumping stations, as a crucial component of the water supply system, are responsible for delivering water from primary pumping stations to various user points, playing a vital role. However, with increasing water demand, some secondary pumping stations are experiencing problems such as aging equipment and low efficiency. Therefore, it is necessary to upgrade secondary pumping stations to improve the stability and efficiency of the water supply system.

[0003] During pump station renovation, insufficient suction well capacity is often encountered, failing to meet the water intake requirements of the new pumps. This leads to a rapid drop in water level in the suction wells, resulting in water supply safety hazards such as turbidity and water supply interruptions. Therefore, capacity expansion is necessary to ensure water supply stability. However, since the original pump station design did not reserve sufficient space, and surrounding buildings or facilities have already occupied most of the space, with no expandable land nearby, the pump station renovation faces significant challenges.

[0004] Currently, the main solutions to this type of problem are to vertically deepen the suction well in the space below the pump room or to integrate the pump control cabinet and water tank into a single unit to reduce the size of the pump. However, these methods all have problems such as high investment and high construction difficulty.

[0005] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

The water supply pipeline for expanding the suction well is connected to the outlet pipe of each suction well of the suction well on one hand, and to the inlet pipe of each pump house of the pump house on the other hand.

[0012] In a preferred embodiment of this utility model, the water supply pipeline for expanding the water intake well adopts a large-diameter water supply pipeline, the diameter of which is determined according to the volume to be expanded in the water intake well and the appropriate length of the pipeline on site.

[0013] In a preferred embodiment of this utility model, the cross-section of the water intake well expansion water supply pipe is elliptical.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0025] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0027] See Figure 1 The diagram shows a modified secondary pump house structure, including a pump house 100, a suction well 200, and a suction well expansion water supply pipeline 300.

[0028] The pump house 100 is equipped with several water supply pump sets 110. The inlet of each water supply pump set 110 is connected to the pump house inlet pipe 120, and its outlet is connected to the external water supply pipe 10 through the pump house outlet pipe 130. Each pump house inlet pipe 120 is equipped with a shut-off valve 121 to control the on / off state and flow rate of the pump house inlet pipe 120. Each pump house outlet pipe 130 is equipped with a shut-off valve 131 to control the on / off state and flow rate of the pump house outlet pipe 130.

[0029] The pump room 100 is equipped with several staircases 140 to facilitate maintenance personnel to inspect and maintain the water supply pump set 110 inside the pump room 100. A water collection pit 150 is installed inside the pump room 100, and the water collection pit 150 is connected to a drain pipe 151. The water collection pit 150 is used to collect the water accumulated in the pump room 100 and discharge it outside the pump room 100 through the drain pipe 151.

[0030] The water intake well 200 is equipped with a water intake pipe 210 and several water intake pipes 220. The water intake well 200 introduces water into the water intake well through the water intake pipe 210.

[0031] The water supply pipe 300 for expanding the water intake well is horizontally arranged between the pump house 100 and the water intake well 200. The water supply pipe 300 is connected to the water outlet pipe 220 of each water intake well of the water intake well 200 on one hand, and to the water inlet pipe 120 of each pump house of the pump house 100 on the other hand.

[0032] The water supply pipe 300 for expanding the suction well adopts a large-diameter water supply pipe, the diameter of which is determined according to the volume to be expanded in the suction well and the appropriate length of the pipeline on site. The cross-section of the water supply pipe 300 for expanding the suction well is elliptical to enhance the self-cleaning ability at low flow rates and reduce bottom sedimentation. An automatic air vent valve (not shown in the figure) is installed at the top of the water supply pipe 300 for expanding the suction well to prevent air resistance from affecting the water pump's suction.

[0033] A sludge discharge port (not shown in the figure) is provided at the lowest point of the bottom of the water supply pipeline 300 of the water intake well. A sludge discharge valve (not shown in the figure) is installed on the sludge discharge port to clean the sediment regularly and prevent blockage.

[0034] In view of emergency situations such as sudden changes in water quality in the pipeline, a V-shaped guide channel (not shown in the figure) is opened at the bottom of the water intake well expansion water supply pipeline 300. It is used to guide the mud and sand at the bottom of the water intake well expansion water supply pipeline 300 to concentrate towards the mud discharge port, and finally clean it through the mud discharge valve.

[0035] Because it is placed outdoors for a long time, the outer surface of the water supply pipe 300 for the expansion of the water intake well is equipped with an insulation layer and an anti-corrosion coating.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
