Abstract
Description
Technical Field
[0001] This utility model relates to the field of small pumping station technology, and in particular to a pumping station adapted to small-scale irrigation and drainage in plain lake areas. Background Technology
[0002] The plains and lake areas are low-lying, and during the flood season, the river levels rise, requiring the drainage of floodwater to external rivers. During the irrigation season, the river levels are shallow, requiring the introduction of river water into irrigation canals. The traditional layout is to arrange the intake gate and pumping station side by side, followed by a box culvert passing through the dike. This layout is common for pumping stations with large irrigation and drainage areas. However, for inland rivers with small flow rates and low water quality, the traditional design method is costly and requires a large construction site. The structural optimization of pumping stations for both small flow irrigation and drainage has always been a topic of discussion in water conservancy.
[0003] Considering the significant difference between irrigation and drainage water levels, drainage pumping stations have a smaller impact on irrigation water flow. However, existing drainage and irrigation pumping stations are mostly built and used separately, resulting in higher construction costs and longer construction periods, thus increasing investment costs. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a pumping station suitable for small-scale irrigation and drainage in plain lake areas, aiming to improve the problem that existing pumping stations for drainage and irrigation are mostly built and used separately, resulting in high construction costs and long construction periods.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pumping station adapted to small-scale irrigation and drainage in plain lake areas, comprising a roadbed, a precast reinforced concrete pipe at the bottom of the roadbed, a concrete pad on the outer wall of the precast reinforced concrete pipe, a submersible pump connected to the right end of the concrete pad, a concrete cushion layer fixedly connected to the left side of the concrete pad, a reinforced concrete transition section structure fixedly connected to the top of the concrete cushion layer, a precast solid hexagonal block slope protection first fixedly connected to the outer wall of the reinforced concrete transition section structure, a trash rack on the top right side of the concrete cushion layer, a reinforced concrete pump chamber on the right side of the roadbed, a pump house fixedly connected to the top of the reinforced concrete pump chamber, an inspection hole at the bottom of the pump house, a reinforced concrete outlet transition section installed at the bottom of the reinforced concrete pump chamber, and a precast solid hexagonal block slope protection second installed at the top of the reinforced concrete outlet transition section.

[0008] As a further description of the above technical solution:
[0009] A ladder is fixedly connected to the top of the inner wall of the reinforced concrete pump room.

[0012] As a further description of the above technical solution:
[0013] An inspection hole is provided on the top left side of the reinforced concrete pump room.
[0014] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:
[0017] Multiple crossbeams are installed on both the left and right sides of the inner wall of the reinforced concrete pump room.
[0018] This utility model has the following beneficial effects:
[0019] 1. In this utility model, during the irrigation period, the gate is opened to introduce river water into the channel to meet the irrigation function of farmland. During the drainage period, the gate is closed and the submersible pump is turned on to pump the floodwater in the channel into the river to ensure the safety of crops. The integrated irrigation and drainage design can save engineering costs and has a compact structure.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a pumping station suitable for small-scale irrigation and drainage in plain lake areas, comprising a roadbed 18, a precast reinforced concrete pipe 6 at the bottom of the roadbed 18, a concrete pad 5 on the outer wall of the precast reinforced concrete pipe 6, a submersible pump 7 connected to the right end of the concrete pad 5, a concrete cushion layer 4 fixedly connected to the left side of the concrete pad 5, a reinforced concrete transition section structure 2 fixedly connected to the top of the concrete cushion layer 4, a precast solid hexagonal block slope protection 3 fixedly connected to the outer wall of the reinforced concrete transition section structure 2, a trash rack 1 on the top right side of the concrete cushion layer 4, a reinforced concrete pump chamber 9 on the right side of the roadbed 18, a pump house 10 fixedly connected to the top of the reinforced concrete pump chamber 9, an inspection hole 12 at the bottom of the pump house 10, a reinforced concrete outlet transition section 16 installed at the bottom of the reinforced concrete pump chamber 9, and a precast solid hexagonal block slope protection 2 17 installed at the top of the reinforced concrete outlet transition section 16.
[0032] Specifically, the roadbed 18 adopts a layered filling and compaction process, selecting soil and rock materials with good compaction and stability to ensure the strength and rigidity of the roadbed 18, effectively resisting foundation settlement and deformation, and providing a flat and solid foundation for the superstructure. The concrete pad 5 evenly distributes the pressure transmitted from the precast reinforced concrete pipe 6, preventing the pipe from being damaged due to excessive local stress. The concrete cushion layer 4 provides a flat and solid foundation platform for the entire water intake system, which can not only bear the weight of the superstructure, but also effectively prevent water flow from scouring and eroding the foundation.
[0033] Please see the appendix Figure 2 - Appendix Figure 5 An entrance hole 11 is provided in the middle of the top surface of the reinforced concrete pump room 9, and a ladder 13 is fixedly connected to the top of the inner wall of the reinforced concrete pump room 9.
[0034] Specifically, the ladder 13 helps users move up and down within the access hole 11.
[0035] Please see the appendix Figure 1 - Appendix Figure 3 An inspection platform 15 is provided on the inner wall of the reinforced concrete pump room 9, and a gate 8 is installed on the left side of the inner wall of the reinforced concrete pump room 9.
[0036] Specifically, gate 8 can effectively control the flow of water, achieve precise regulation of water level, and meet the operating requirements of the pump room under different working conditions.
[0037] Please see the appendix Figure 5 - Appendix Figure 7 An inspection hole 12 is provided on the top left side of the reinforced concrete pump room 9. Multiple crossbeams 14 are installed on both the left and right sides of the inner wall of the reinforced concrete pump room 9.
[0038] Specifically, the crossbeam 14 is tightly connected to the concrete structure of the pump chamber's inner wall, forming a spatial frame structure that can effectively disperse and transfer these loads, reduce stress concentration in the structure, and improve the pump chamber's resistance to deformation and seismic performance.
[0039] Working principle: The reinforced concrete pump room section 9 adopts a reinforced concrete structure. A wall and gate 8 are set in the middle to separate the inlet pool and the outlet pool. A submersible pump 7 is installed vertically in the inlet pool. The outlet pipe of the submersible pump 7 passes through the wall to the outlet pool. A flap gate is set at the end of the outlet pipe. A pump house 10 is built on the top of the reinforced concrete pump room section 9. The top plate of the reinforced concrete pump room 9 is provided with inspection holes 12 and manholes 11 for maintenance of pump house 10 and gate 8. The plant also has electrical equipment for the operation of submersible pump 7. The reinforced concrete outlet transition section 16 is a reinforced concrete trumpet-shaped section. The top slope adopts precast solid hexagonal block slope protection 2 17, which gradually widens and the side wall gradually decreases in height, connecting with the riverbed. Consider whether to add a trash rack 1 depending on the situation.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
