Description

Technical Field

[0001] The present invention belongs to the technical field of water intake engineering, and particularly relates to a wharf water intake pump station. Background Art

[0002] In a thermal power plant, the water intake pump station, as a core infrastructure, undertakes the important task of providing sufficient water sources for the make-up water system, cooling water system, domestic water system, and fire protection water system. Power plants using surface water as the water source usually need to set up water intake pump stations at rivers, lakes, reservoirs, etc. respectively to transport the surface water to the power plant. However, in areas with water source environments, the construction and operation of the pump station are extremely susceptible to various factors such as aquatic animals and plants, sediment, floating objects, riverbed geology, and extreme hydrological conditions. Therefore, how to set up a water intake pump station in a complex water area environment and obtain qualified raw water is a technical problem that needs to be solved urgently at present. Traditional river water intake pump stations mostly use fixedly installed vertical or horizontal centrifugal pumps as the core water intake equipment, and adopt shaft-type reinforced concrete pump stations. The construction of the deep foundation pit of the shaft is difficult, has strict requirements for geological conditions, and needs to deal with risks such as groundwater leakage and soil collapse. In addition, when the river water level changes greatly, the shaft-type pump station needs to be equipped with a complex adjustment system to adapt to the water level fluctuation, increasing the equipment cost and operation and maintenance difficulty.

[0003] Therefore, there is a need for a wharf water intake pump station that can obtain qualified raw water in a complex water area environment while effectively reducing the operation and maintenance and construction difficulties. Summary of the Invention

[0004] The object of the present invention is to provide a wharf water intake pump station that can obtain qualified raw water in a complex water area environment while effectively reducing the operation and maintenance and construction difficulties.

[0005] To achieve the above object, the technical solution adopted by the present invention is: A wharf water intake pump station includes four concrete piles symmetrically arranged in pairs and buried at the bottom on one side of the water bottom of the power station wharf, a pump station platform arranged on the tops of the four concrete piles and flush with the power station wharf, a plurality of water intake pumps arranged on the pump station platform at intervals along its length direction, steel pipe piles located below the pump station platform and corresponding to each water intake pump, and parallel water supply pipelines respectively connected to each water intake pump. Among them, the inside of the steel pipe pile is hollow, its upper end is connected to the pump station platform, its lower end is buried at the bottom on one side of the power station wharf and a non-dispersible underwater concrete layer is blocked at the port, and each steel pipe pile is provided with an intake grille at a position close to the water bottom; the upper part of the water intake pump is located on the pump station platform and connected to the water supply pipeline, and its lower part penetrates the pump station platform and extends into the steel pipe pile and reaches its intake grille.

[0006] A further improvement of the technical solution of the present invention lies in that: the water intake pump includes a pump body disposed on the pumping station platform through a pump foundation and connected to the water supply pipeline, and a water intake pipe with its upper end connected to the pump body and its lower end passing through the pumping station platform and extending into the steel pipe pile, and the lower port of the water intake pipe is close to the water intake grille of the steel pipe pile.

[0007] A further improvement of the technical solution of the present invention lies in that: the upper ends of the four concrete piles are respectively connected to the bottom of the pumping station platform through embedded steel bars, and the four concrete piles are respectively sleeved with steel hoops at positions between the water intake grille of the steel pipe pile and the water bottom; hooks are respectively arranged at the four corners of the top surface of the pumping station platform.

[0008] A further improvement of the technical solution of the present invention lies in that: a protective net is circumferentially wrapped around the pumping station platform, and the upper part of the protective net is hung on the four hooks on the top surface of the pumping station platform, and its lower part is hung on the steel hoops of the four concrete piles.

[0009] A further improvement of the technical solution of the present invention lies in that: the upper end of the steel pipe pile is connected to the bottom of the pumping station platform through embedded steel bars; the water intake grille includes a plurality of vertically strip-shaped through holes evenly spaced along the circumference of the steel pipe pile.

[0010] A further improvement of the technical solution of the present invention lies in that: parallel lubricating water pipes for supplying lubricating water to the inside are respectively connected to the pump bodies of the respective water intake pumps; parallel chlorine adding pipes for supplying chlorine water to the inside are respectively connected to the respective steel pipe piles.

[0011] A further improvement of the technical solution of the present invention lies in that: a lifting support is arranged on the pumping station platform along the arrangement direction of the respective water intake pumps, and a mobile electric hoist capable of hoisting the respective water intake pumps is arranged on the lifting support above the water intake pumps.

[0012] A further improvement of the technical solution of the present invention lies in that: the lifting support includes a cross plate arranged along the length direction of the pumping station platform and located above the water intake pumps and four support rods vertically arranged symmetrically in pairs between the cross plate and the pumping station platform, wherein the upper ends of the support rods are connected to the bottom of the cross plate and their lower ends are connected to the pumping station platform; the mobile electric hoist is arranged on the cross plate of the lifting support.

[0015] The present invention adopts a connection process for pre-burying steel bars between concrete piles and steel pipe piles. During construction, it only needs to bind or weld the steel bars at the top of the piles and the steel bars of the pump station platform, simplifying the on-site pouring process and shortening the construction period. Moreover, the concrete piles and steel pipe piles form an integral stress structure with the pump station platform through pre-buried steel bars, which can adapt to the complex working conditions in the wharf area.

[0016] The water intake grille of the steel pipe pile adopted in the present invention is arranged near the bottom of the water. It filters suspended solids through vertically strip-shaped holes evenly distributed in the circumferential direction, preferentially extracts deep clean raw water, effectively avoids the problem of turbid water quality. Moreover, the lower port of the steel pipe pile seals the underwater non-dispersible concrete layer, completely isolating the sediment from surging in from the bottom of the pile, ensuring the smoothness of the water intake channel.

[0017] The present invention adopts multiple water intake pumps to work together through a parallel water supply pipeline. The total water supply volume is superimposed to meet the large flow demand. When a single pump fails, other pump groups can still operate normally, ensuring the continuity of water supply.

[0018] The protective net adopted in the present invention wraps the pump station platform circumferentially and is fixed through hooks and steel hoops, intercepting aquatic organisms from entering the pump station and ensuring the safety of equipment.

[0019] The lifting bracket adopted in the present invention cooperates with a mobile electric hoist, which can realize the rapid lifting, maintenance or replacement of the pump body, greatly reducing the labor and time costs. Brief Description of the Drawings

[0021] The following further describes the present invention in detail with reference to the embodiments: As Figure 1 and Figure 2 shown, the present invention provides a wharf water intake pump station, which includes four concrete piles 2, a pump station platform 3 supported by the four concrete piles 2, several water intake pumps 5 arranged on the pump station platform 3, steel pipe piles 4 adapted to the several water intake pumps 5, and a parallel water supply pipeline 6 connected to each water intake pump 5.

[0022] Among them, four concrete piles 2 are symmetrically arranged in pairs, and the bottoms of the four concrete piles 2 are all buried in the bottom of the water on one side of the power station wharf 1. The pump station platform 3 is arranged on the tops of the four concrete piles 2. The upper ends of the four concrete piles 2 are respectively connected to the bottom of the pump station platform 3 through embedded steel bars, that is, vertical steel bars (anchor bars) are buried at the pile tops of the concrete piles 2 in advance. When the pump station platform 3 is constructed, the steel bars at the pile tops of the concrete piles 2 are tied or welded to the steel bars of the pump station platform 3 to form an integral stress structure, so that the pump station platform 3 is docked and leveled with the power station wharf 1.

[0023] A number of water intake pumps 5 are arranged on the pump station platform 3 and are arranged at intervals along the length direction of the pump station platform 3, and the intervals are uniform or non-uniform. Below the pump station platform 3, steel pipe piles 4 corresponding to each water intake pump 5 are provided. Here, "corresponding" means that the number and position of the steel pipe piles 4 correspond to the water intake pumps 5, that is, the number of water intake pumps 5 arranged on the pump station platform 3 is the same as the number of steel pipe piles 4 located below the pump station platform 3. Each water intake pump 5 on the pump station platform 3 is equipped with a corresponding steel pipe pile 4 located below the pump station platform 3, and the center line of the water intake pump 5 overlaps with the center line of the corresponding steel pipe pile 4.

[0026] The water in the water area can enter the interior of the steel pipe pile 4 through the water inlet grid 4-1, and the water intake pump 5 can pump water to the top of the pump station platform 3 through the water intake pipe 5-2. The raw water sucked by each water intake pump 5 is collected into the main network through the parallel water supply pipe 6 and transported to the power station or other water facilities.

At the same time, in order to inhibit the growth of algae and microorganisms in the raw water in the steel pipe pile 4, each steel pipe pile 4 is respectively connected with a parallel chlorination pipe 11 for supplying chlorine water therein, thereby ensuring the quality of the raw water.

[0029] Furthermore, a lifting bracket 7 is arranged on the pump station platform 3 along the arrangement direction of each water intake pump 5, and a mobile electric hoist 8 located above the water intake pump 5 and capable of lifting each water intake pump 5 is arranged on the lifting bracket 7. Specifically, the lifting bracket 7 includes a horizontal plate 7-1 arranged along the length direction of the pump station platform 3 and located above the water intake pump 5, and four support rods 7-2 symmetrically arranged vertically between the horizontal plate 7-1 and the pump station platform 3, wherein the upper end of the support rod 7-2 is connected to the bottom of the horizontal plate 7-1, and the lower end thereof is connected to the pump station platform 3. The mobile electric hoist 8 is arranged on the horizontal plate 7-1 of the lifting bracket 7, and the mobile electric hoist 8 can move along the horizontal plate 7-1 of the lifting bracket 7 to realize rapid lifting, maintenance or replacement of the water intake pump 5, thereby greatly reducing the difficulty of maintenance and labor costs. Among them, an I-beam track or an H-beam track can be set on the cross plate 7-1, and the mobile electric hoist 8 is inserted into the track through wheels or rollers to achieve linear movement along the cross plate 7-1.
