Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering, and particularly relates to a steel pipe barrel pumping station suitable for water intake in a reservoir area. Background Art

[0002] In conventional water conservancy projects, the water source of the pumping station is to draw water from a reservoir, and the common forms of water intake structures are fixed and mobile.

[0003] The fixed water intake forms include: tunnel type, diversion open channel, stratified water intake, combined or separate structures; the tunnel type water intake structure is suitable for large reservoirs with a water depth of more than 10m; the diversion open channel water intake structure can choose the combined or separate shore water intake structure form in combination with the topographic and geological conditions of the reservoir bank; the stratified water intake structure is suitable for reservoir areas with a large water depth. In order to obtain raw water with low turbidity and good water quality, the stratified water intake structure can be adopted; the combined or separate water intake structure is suitable for water intake from reservoirs with a relatively shallow water level and clear water quality.

[0004] The mobile water intake forms are mainly floating boat type and cable car type; the floating boat type water intake is suitable for a water level variation range of 10 - 35m or a larger range, the water level rising and falling speed not exceeding 2m / h, the water depth in the dry season not less than 1m, small wind and waves, and a stable reservoir bank slope with a slope angle greater than 60°. The cable car type water intake is suitable for a water level variation range of 10 - 35m, the water level rising and falling speed not exceeding 2m / h, and the bank slope inclination angle between 10° and 28°.

[0005] The fixed water intake structure has problems such as a large floor area, a large amount of civil engineering construction, high investment, a long construction period, and underwater construction, and it has relatively high requirements for the topographic and geological conditions of the reservoir bank.

[0006] The mobile water intake forms are mainly floating boat and cable car type water intakes. The floating boat has a small amount of civil engineering, no underwater construction, convenient construction, and does not occupy land, but its operation and management are inconvenient, the hull has poor adaptability to wind and waves, poor safety, and the joints are worn greatly due to the rising and falling of the reservoir water level and need to be disassembled and replaced; the cable car type water intake has a small amount of underwater construction work, better stability than the floating boat, and can adapt to larger wind and waves, but has a higher investment, relatively high requirements for the topographic and geological conditions of the bank slope, and its ramp occupies the shore land.

[0007] The above two forms of water intake structures have high investment, great construction difficulty, and a long construction period, and because they need to occupy the shore land, the construction is greatly restricted in areas with limited land use such as ecological protection and basic farmland, which is not conducive to project construction. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a steel tube barrel pump station suitable for water intake in a reservoir area. The steel tube barrel pump station is integrally submerged below the water surface of the reservoir, does not need to occupy the land on the shore, has an overall modular prefabricated design, has low requirements for terrain and geology, small construction difficulty, high construction efficiency and is convenient for management.

[0009] In response to the above technical problem, the technical solution provided by the present invention is a steel tube barrel pump station suitable for water intake in a reservoir area, including a bottom concrete foundation. A vertical steel tube barrel assembly and a connecting pipe are arranged in the concrete foundation. The concrete foundation is integrally sunk in the reservoir inundation area near the shore, and the upper end of the vertical steel tube barrel assembly is used to be below the water surface. The vertical steel tube barrel assembly includes a water inlet tube barrel and a water outlet tube barrel. The lower ends of the water inlet tube barrel and the water outlet tube barrel are connected through a connecting pipe. The upper ends of the water inlet tube barrel and the water outlet tube barrel protrude from the concrete foundation. A water inlet pipe is arranged in the water inlet tube barrel, and the outer end of the water inlet pipe extends outward into the reservoir. A first water pump and a water outlet pipe connected to the first water pump are arranged in the water outlet tube barrel, and the water outlet pipe is used to supply water to the shore.

[0010] Further, two groups of water outlet tube barrels are arranged at intervals in the transverse direction, two water outlet tube barrels in each group are arranged at intervals in the longitudinal direction, and the lower ends of the water outlet tube barrels in each group are connected through a longitudinal connecting pipe. The two longitudinal connecting pipes are connected through two transverse connecting pipes arranged at intervals in the longitudinal direction, and the lower end of the water outlet tube barrel is connected to one of the transverse connecting pipes.

[0011] Further, the upper ends of the water outlet pipes of the two longitudinally arranged water outlet tube barrels are connected through a longitudinal connecting pipe. The two longitudinal connecting pipes are connected through a transverse connecting pipe, and a water diversion pipe extending towards the shore is connected to the transverse connecting pipe.

[0012] Further, the upper ends of the water outlet tube barrel and the water inlet tube barrel protrude from the concrete foundation, and a first support member is supported and fixed between the longitudinal connecting pipe and the concrete foundation.

[0013] Further, the first support member is a drain pipe. The upper end of the drain pipe is connected and fixed to the longitudinal connecting pipe, the lower end of the drain pipe is connected and fixed to the corresponding longitudinal connecting pipe, and a maintenance valve is arranged on the drain pipe.

[0014] Further, a second support member is supported and fixed between the water diversion pipe and the concrete foundation.

[0015] Further, it further includes a steel floating drum. The steel floating drum is used to float on the reservoir. A second water pump is arranged at the lower end of the steel floating drum. The water inlet pipe includes a first branch pipe and a second branch pipe, and the second water pump is connected to the first branch pipe.

[0016] Furthermore, a pump base is provided at the lower end of the first water pump, and the pump base is fixedly arranged on the connecting pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) The bottom concrete foundation and the vertical steel pipe cylinder assembly are integrally submerged below the water surface of the reservoir. An inlet pipe is provided at the upper end of the inlet pipe cylinder. The inlet pipe introduces water into the inlet pipe cylinder and then into the bottom connecting pipe. The first water pump in the outlet pipe cylinder pumps water into the outlet pipe and then supplies water outward. At the same time, the steel pipe cylinder pumping station is set in the reservoir inundation area close to the shore, without occupying the shore land. The construction of the pumping station is not restricted by the area of use.

Detailed implementation manners

[0034] To make the objectives, 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 accompanying drawings in the embodiments of the present application: Specific Embodiment 1:

[0036] A steel tube barrel pumping station applicable to water intake in the reservoir area of the present invention is applicable to pumping station projects in the reservoir area where the water level amplitude changes greatly, the construction land is restricted by factors such as being in the ecological protection red line area, basic farmland area, difficult land acquisition, or limited by terrain, geological conditions, construction conditions, project investment, etc. At the same time, in this embodiment, as Figure 2 shown, the length direction of the longitudinal connecting pipe 7 is longitudinal, and the length direction of the transverse connecting pipe 8 is transverse.

[0037] Reference Figures 1 to 6 For a steel tube barrel pump station applicable to water intake in a reservoir area (hereinafter referred to as the tube barrel pump station) of the present invention, it includes a bottom concrete foundation 1. A vertical steel tube barrel assembly 2 and a connecting pipe 3 are arranged in the concrete foundation 1. The whole concrete foundation 1 is sunk in the reservoir inundation area near the shore, and the upper end of the vertical steel tube barrel assembly 2 is used to be below the water surface. The vertical steel tube barrel assembly 2 includes a water inlet tube barrel 21 and a water outlet tube barrel 22. The lower ends of the water inlet tube barrel 21 and the water outlet tube barrel 22 are connected through the connecting pipe 3. The upper ends of the water inlet tube barrel 21 and the water outlet tube barrel 22 are exposed out of the concrete foundation 1. A water inlet pipe 4 is arranged in the water inlet tube barrel 21, and the outer end of the water inlet pipe 4 extends outward into the reservoir. A first water pump 6 and a water outlet pipe 5 connected to the first water pump 6 are arranged in the water outlet tube barrel 22, and the water outlet pipe 5 is used to supply water to the shore.

[0038] With such an arrangement, the bottom concrete foundation 1 and the vertical steel tube barrel assembly 2 are integrally immersed below the water surface of the reservoir. The water inlet pipe 4 is arranged at the upper end of the water inlet tube barrel 21. The water inlet pipe 4 introduces water into the water inlet tube barrel 21 and then into the bottom connecting pipe 3. The first water pump 6 in the water outlet tube barrel 22 pumps water into the water outlet pipe 5 and then supplies water outward. At the same time, the steel tube barrel pump station is arranged in the reservoir inundation area near the shore, without occupying the land on the shore. The construction of the pump station is not restricted by the area of use. At the same time, with the overall modular prefabricated design, it can be integrally installed at the designated position during actual installation, with low requirements for terrain and geology, small construction difficulty, short construction period, high construction efficiency and convenient management.

[0039] Specifically, in this embodiment, the connecting pipe 3 adopts a DN1500 steel tube barrel. The two ends of the connecting pipe 3 are blocked. The water inlet tube barrel 21 and the water outlet tube barrel 22 are DN800 steel tube barrels. The outside of the connecting pipe 3 is a C30 reinforced concrete foundation 1. The connecting pipe 3 is provided with connecting holes corresponding to the water inlet tube barrel 21 and the water outlet tube barrel 22. The water inlet tube barrel 21 and the water outlet tube barrel 22 are hermetically fixed on the corresponding connecting holes, so that the vertical steel tube barrel assembly 2 and the connecting pipe 3 form a connected steel cylinder water tank.

[0040] Specifically, in this embodiment, as Figure 2 shown, two groups of water outlet tube barrels 22 are arranged at intervals transversely, and two water outlet tube barrels 22 in each group are arranged at intervals longitudinally. In this embodiment, the lower ends of each group of water outlet tube barrels 22 are connected through a longitudinal connecting pipe 3. The two longitudinal connecting pipes 3 are connected through two transverse connecting pipes 3 arranged at intervals longitudinally. The water outlet tube barrel 22 is connected to one of the transverse connecting pipes 3. The layout type of the connecting pipe 3 is "II" shaped. As Figure 3 、 4 shown, a first water pump 6 is arranged in each water outlet tube barrel 22. The lower end of the first water pump 6 is supported and fixed in the corresponding connecting pipe 3 through a water pump base 19.

[0041] The water outlet pipe barrel 22 adopts a structure in which multiple groups are arranged at intervals and are interconnected through the connecting pipes 3, which can realize simultaneous water intake and water conveyance through multiple pipelines, increase the efficiency of water intake and water conveyance, improve the reliability and stability of the water supply of the entire pumping station, and ensure the continuity of the water supply.

[0042] Preferably, in this embodiment, the upper ends of the water outlet pipes 5 of the two longitudinally oppositely arranged water outlet pipe barrels 22 are connected through the longitudinal connecting pipes 7, the two longitudinal connecting pipes 7 are connected through the transverse connecting pipe 8, and a water diversion pipe 9 extending towards the shore is connected to the transverse connecting pipe 8. At the same time, as Figure 2 shown, on the longitudinal connecting pipe 3, on both sides of the transverse connecting pipe 3, a group of check valves 20 are respectively arranged. Connecting the water outlet pipes 5 through the longitudinal connecting pipes 7 and the transverse connecting pipe 8 can optimize the layout of the water conveyance network, enhance the flexibility of the water conveyance system, and facilitate adjusting the water conveyance path and water volume distribution according to the actual water use requirements.

[0043] Preferably, in this embodiment, as Figure 4 、 5 、6 shown, the upper ends of the water outlet pipe barrel 22 and the water inlet pipe barrel 21 extend out of the concrete foundation 1, and a first support member 10 is supported and fixed between the longitudinal connecting pipe 7 and the concrete foundation 1. Specifically, in this embodiment, the first support member 10 is a drain pipe extending vertically. The upper end of the drain pipe is connected and fixed to the corresponding longitudinal connecting pipe 7, the lower end of the drain pipe is connected and fixed to the corresponding longitudinal connecting pipe 3, and a maintenance valve 13 is arranged on the drain pipe. In this embodiment, the maintenance valve 13 is a gate valve. In other embodiments, the maintenance valve 13 can also be a butterfly valve.

[0044] Using the drain pipe as the first support member 10 has both the functions of support and drainage. While supporting the pipeline, when it is necessary to repair, maintain the pipeline system or drain the accumulated water in the pipeline, the maintenance valve 13 can be opened, and the water in the pipeline can be drained through the drain pipe, which is convenient, fast, and improves the maintenance convenience and working efficiency of the pumping station.

[0045] In this embodiment, as Figure 1 shown, the pipe barrel pumping station further includes a power distribution room 18. Specifically, the power distribution room 18 is arranged on the shore of the reservoir. If there are conditions for constructing permanent buildings on the shore, a box-type substation can be adopted. If there are no construction conditions on the shore, a simple steel floating body power distribution room 18 can be adopted. The floating body is a steel fully welded structure, the upper house adopts double-layer profiled composite color steel plates, the roof adopts high-wave plates, the wall adopts low-wave plates, the roof is a non-accessible roof, and the roof and wall materials are required to be thermal insulation materials (with a waterproof and breathable layer and a heat insulation and reflection foil), and the service life is not less than 30 years. All the equipment of the pipe barrel pumping station of the present invention adopts electric control, and the pipe barrel pumping station all adopts automatic control.

[0046] In this embodiment, for a reservoir with a small water level fluctuation range, water inlets at different elevations can be arranged at intervals along the vertical direction on the circumferential surface of the water inlet pipe cylinder 21 according to the water level fluctuation range during the operation of the reservoir, so as to achieve layered water intake.

[0047] For the case of a large water level fluctuation range in the reservoir, a first-level steel floating cylinder 14 is provided to pump water into the water inlet pipe cylinder 21. Specifically, the steel floating cylinder 14 is used to float on the reservoir. A second water pump 15 is arranged at the lower end of the steel floating cylinder 14. The water inlet pipe 4 includes a first branch pipe 41 and a second branch pipe 42. The second water pump 15 is communicated with the first branch pipe 41 through a connecting water pipe 43.

[0048] Specifically, a movable joint 17 and a check valve 20 are respectively arranged at both ends of the connecting water pipe 43. One end of the connecting water pipe 43 is connected with the second water pump 15 through the check valve 20, and the other end is communicated with the first branch pipe 41 through the movable joint 17.

[0049] The movable joint 17 can rotate 360 degrees to adapt to the floating change of the steel floating cylinder 14. The structure and function of the movable joint 17 are common knowledge well-known to those skilled in the art and will not be elaborated here.

[0050] By using the movable joint 17 to adapt to the water level change of the reservoir, when the water level of the reservoir is high and the second branch pipe 42 is immersed in water, water enters through the second branch pipe 42 and the upper opening of the water inlet pipe cylinder 21. When the water level of the reservoir is low, the second water pump 15 is used to supply water into the water inlet pipe cylinder 21. The steel floating cylinder 14 can automatically adjust its height according to the water level change, ensuring that the water inlet pipe 4 is always in a suitable water intake position to adapt to the case of a large water level fluctuation range in the reservoir.

[0051] As Figure 1 、 2 shown, in this embodiment, a maintenance hole 16 is also provided in the pipe cylinder pump station. Specifically, the upper end of the water inlet pipe cylinder 21 is an opening, and this opening serves as the maintenance hole 16. Through the maintenance hole 16, it is possible to enter the vertical steel pipe cylinder assembly 2 and the connecting pipe 3 inside, and at the same time, water is supplied into the water inlet pipe cylinder 21 through the maintenance hole 16 at high water levels. At this time, according to actual needs, the second branch pipe 42 can also be connected to a set of steel floating cylinder 14 and a second water pump 15 to cooperate with the first branch pipe 41 to supply water at low water levels.

[0052] Specifically, when the reservoir is at a low water level suitable for maintenance, a submersible pump is lowered from the maintenance hole 16 to the bottom connecting pipe 3, and the submersible pump is used to drain the water in the vertical steel pipe cylinder assembly 2 and the connecting pipe 3 for maintenance.

[0053] In other embodiments, according to the maintenance requirements, a drain pipe can be provided inside the concrete foundation 1. The inner end of the drain pipe is communicated with the connecting pipe, and the outer end of the drain pipe extends out of the concrete foundation 1 to communicate with the outside. At the same time, a closing gate is installed at the outer end of the drain pipe. When the water level is low and suitable for maintenance, the gate is opened, and the water, sediment, etc. in the connecting pipe 3 and the vertical steel pipe barrel assembly 2 are discharged along the drain pipe, and the staff can enter for maintenance.

[0054] In other embodiments, the upper end of the water inlet pipe barrel 21 can be designed to be blocked, and only a passage for the water inlet pipe 4 to pass through is reserved. The inspection hole 16 can be arranged on the circumferential surface of the water inlet pipe barrel 21. At this time, the second branch pipe 42 is directly communicated with the reservoir, and water is supplied into the water inlet pipe barrel 21 through the second branch pipe 42 at high water levels, realizing multiple water supply methods.

[0055] The working process of this application is as follows:

[0056] First, install the concrete foundation 1 integrated with the vertical steel pipe barrel assembly 2 and the connecting pipe 3 to the submerged area of the reservoir near the shore, and the entire vertical steel pipe barrel assembly 2 is immersed in water. Connect the electrical equipment on the vertical steel pipe barrel assembly 2 to the power distribution room 18.

[0057] Connect the first branch pipe 41 of the water inlet pipe barrel 21 to the second water pump 15 through the connecting water pipe 43. When the water level is high and the water inlet pipe barrel 21 is submerged in water, the second water pump 15 does not need to be started. At this time, the vertical steel pipe barrel assembly 2 and the connecting pipe 3 are automatically filled with water, and water is supplied to the shore using the first water pump 6. When the water level is low and the water inlet of the water inlet pipe barrel 21 and the water inlet pipe 4 are exposed above the water surface, use the second water pump 15 to supply water into the water inlet pipe barrel 21, and then use the first water pump 6 to supply water to the shore, realizing multiple water supply methods.

[0058] In summary, through the pipe barrel pumping station of the present invention, problems in irrigation and water supply projects for reservoir water intake can be solved, including being restricted by the nature of construction land, that is, the project area involves permanent basic farmland and ecological protection red lines, making the construction land approval difficult. Being restricted by land acquisition factors, that is, the land use nature of the project area is compliant but land acquisition is difficult. Being restricted by the topographic conditions of the project area, that is, the terrain slope of the project area is too steep to be suitable for arranging structures. Being restricted by geological conditions, that is, the geological conditions in the area are poor and the shore slope is unstable, etc., making it unsuitable for arranging structures. Being restricted by construction funds, that is, the project construction funds are less, or the construction investment using other structures is relatively large.

[0059] Being restricted by the construction period, that is, some projects have short construction period requirements, the cost of temporary measures such as setting up temporary cofferdams is high and the construction is difficult, and the construction needs to be carried out during low water level periods in combination with reservoir operation scheduling. Being restricted by the water level fluctuation, that is, the water level fluctuation in the reservoir area has a great impact on the water intake method and unit selection of the pumping station, the water level fluctuation and wind waves endanger the safety of the water intake structure, the unit operation efficiency is low, the energy consumption is large, and the pumping station efficiency is low.

[0060] Example 2: This example provides a different tube pumping station. Different from Example 1, as Figure 7 , 8 shown, according to the actual usage requirements, in this example, the connecting pipe 3 is in a "T" shape. The connecting pipe 3 includes a horizontal connecting pipe 3 and a vertical connecting pipe 3. Among them, three water outlet tubes 22 are arranged at intervals along the horizontal direction on the horizontal connecting pipe 3, and a water inlet tube 21 is arranged on the vertical connecting pipe 3. The water outlet pipes 5 of the three water outlet tubes 22 converge together and are connected with a water diversion pipe 9.

[0061] In this example, a second support member 11 is supported and fixed between the water diversion pipe 9 and the concrete foundation 1. The second support member 11 includes a support base and a support rod. The opposite ends of the support rod and the support base are respectively fixed to the water diversion pipe 9 and the concrete foundation 1.

[0062] Example 3: This example provides a different tube pumping station. Different from Example 1, as Figure 9 , 10 shown, according to the actual usage requirements, in this example, the connecting pipe 3 is in a "one" shape. One water outlet tube 22 is arranged on each of the two axial sides of the connecting pipe 3, and a water inlet tube 21 is arranged between the two water outlet tubes 22.

[0063] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0064] In the description of the embodiments of the present application, it should be noted that if terms such as "upper", "lower", "horizontal", "inner", etc. are used to indicate the orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship when the invention product is usually placed. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present application. In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0065] In addition, if the term "horizontal" appears, it does not mean that the component is required to be absolutely horizontal, but it can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and it does not mean that the structure must be completely horizontal, but it can be slightly inclined.
