Description

Technical Field

[0001] The invention belongs to the technical field of test water tanks, and in particular relates to a large test water tank-reservoir-corridor circulation and dispatching system. Background Art

[0002] In experimental research on civil engineering, hydraulic engineering and marine engineering, large test pools are important tools for simulating hydrodynamic characteristics, fluid motion laws and related phenomena. However, traditional test pools are usually single-channel pools, which have many problems in water scheduling: ① Low water scheduling efficiency: Due to the single-channel design of existing pools, the optimization of water scheduling paths is limited, resulting in complex paths, large hydraulic losses, slow speeds, and long switching time between pools and reservoirs when scheduling water flows, making it difficult to respond quickly to experimental needs; ② Poor adaptability to experimental needs: A single scheduling method lacks flexibility and cannot meet the rapid switching and diversified needs of experimental scenarios, such as the adjustment of different water levels, flow rates and water body distributions; ③ High energy consumption and operating costs: Traditional test pools usually rely on a single-direction pumping design, which results in serious energy waste and a low design. ④ Equipment failure affects the experiment: the redundant design of traditional test pool equipment is insufficient. Once the water pump or other key equipment fails, the experiment is easily interrupted; ⑤ Lack of recycling mechanism: In the existing scheme, the experimental water may be directly discharged into the external environment. The lack of recycling mechanism not only wastes water resources, but also significantly increases the cost of the experiment; ⑥ Low space utilization: The water storage and scheduling system of the pool occupies a large amount of ground or underground space, the civil engineering investment is large, and the structural layout is unreasonable; ⑦ Insufficient foundation safety: Frequent pumping and drainage operations will cause repeated changes in the foundation bearing pressure, which can easily cause uneven foundation settlement and affect the long-term stability and safety of the foundation.

Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. In addition, for the sake of clarity and brevity, the description of known functions and structures is omitted.

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0024] like Figure 1-Figure 9 As shown, a large-scale experimental water pool-reservoir-corridor circulation and dispatching system provided by this embodiment includes: a large-scale water pool bottom 1, an inner reservoir 2, an outer reservoir 3, an inner and outer reservoir channel 4, a lower annular return corridor 5, an injection and drainage pump room 6 and an upper corridor 7; wherein, the large-scale water pool bottom 1 is located in the center of the entire system, and the entire water pool serves as the main storage and use area of ​​the experimental water body; the inner reservoir 2 is arranged around the outside of the large-scale water pool bottom 1, and the lower annular return corridor 5 is arranged around the outside of the inner reservoir 2 for storing and returning a large volume of water; the outer reservoir 3 is arranged around the outside of the lower annular return corridor 5; the inner reservoir 2 and the outer reservoir 3 are arranged around the outside of the lower annular return corridor 5; The inner and outer reservoirs are connected by an inner and outer reservoir channel 4, so that the water levels of the inner and outer reservoirs are always consistent; the injection and drainage pump room 6 is arranged in the outer reservoir 3 on both sides of the lower annular return corridor 5 for injection and drainage; the upper gallery 7 is located above the lower annular return corridor 5 and arranged along the outer side of the large pool bottom 1, and the upper gallery 7 is connected with the large pool bottom 1 and the lower annular return corridor 5 respectively to form a water distribution channel; the injection and drainage pump room 6 includes injection equipment and drainage equipment. The injection equipment can inject water from the outer water reservoir 3 and the inner water reservoir 2 into the large pool bottom 1, and the drainage equipment can discharge the water from the large pool bottom 1 to the outer reservoir 3 and the inner reservoir 2.

[0025] It can be seen that the dispatching system of this embodiment forms a lower structure through the inner reservoir 2, the outer reservoir 3 and the lower annular return corridor 5, and the upper corridor 7 connects the bottom 1 of the large pool to form an upper structure. With such a layered design and the annular return corridor layout, a highly coordinated water body dispatching network is formed, which realizes the storage of large volumes of water within a limited range and optimizes the circulation path of the water flow; and the lower annular return corridor 5 releases the lower space of the pool for installing the equipment required for the experiment, while the upper corridor 7 is arranged along the pool wall, which occupies less space and improves the overall space utilization. In addition, the dispatching system of this embodiment ensures that the pressure above the foundation is constant, maintains the stability of the foundation load, avoids uneven settlement of the foundation due to water injection and drainage operations, and ensures the long-term safety of the foundation.

[0026] In this embodiment, the lower annular return corridor 5 and the upper corridor 7 can be made of concrete, replacing the traditional pipeline system, which significantly reduces the material cost and maintenance requirements, while improving durability. At the same time, it simplifies the construction process and reduces the complexity of equipment maintenance.

[0027] In this embodiment, the water injection equipment includes a water injection pump, a water injection pipe 11 and a water injection valve 13. The water injection pump is connected to the water injection pipe 11. One end of the water injection pipe 11 away from the water injection pump is connected to the top of the lower annular return corridor 5. The water injection valve 13 is arranged on the water injection pipe 11. The drainage equipment includes a drainage pipe 12 and a drainage valve 14. One end of the drainage pipe 12 is connected to the top of the outer reservoir 3, and the other end is connected to the side wall of the lower annular return corridor 5. The drainage valve 14 is arranged on the drainage pipe 12. Specifically, the water supply equipment uses 6 down-suction submersible electric pumps for water supply. Each group of 3 pumps is arranged on both sides of the outer reservoir. Each water pump is equipped with an electric butterfly valve, a total of 6 pumps, to control the water supply flow. Each water injection pump is equipped with a set of gate valves, a total of 6 pumps, to provide conditions for the maintenance of the water pump and the electric butterfly valve; the drainage equipment uses electric butterfly valves for drainage. Each group of 2 pumps is arranged on both sides of the outer reservoir, a total of 4 pumps, and each electric butterfly valve is equipped with a set of gate valves, a total of 4 pumps.

[0028] In this embodiment, a water tank level gauge 8 is provided on the side wall of the large water tank bottom 1, a reservoir level gauge 9 is provided on the outer wall of the outer reservoir 3, and a gallery level gauge 10 is provided on the inner wall of the lower annular return gallery 5 for real-time monitoring of water level changes.

[0029] The dispatching system of this embodiment includes a water injection process and a drainage process; the water injection process is: in the initial state, the drainage valve 14 and the water injection valve 13 are closed, the outer reservoir 3 is not connected to the lower annular return corridor 5, and the water levels of the inner reservoir 2 and the outer reservoir 3 are kept constant through the inner and outer reservoir channels 4; then the water injection operation is started, the water injection valve 13 is opened, the water injection pump is started, and the water flows from the inner reservoir 2 and the outer reservoir 3 into the lower annular return corridor 5 through the water injection pipe 11, and then enters the bottom 1 of the large water pool through the upper gallery 7; the water pool level meter 8, the reservoir level meter 9, and the gallery level meter 10 respectively monitor the water levels of the water pool, reservoir and gallery in real time, and dynamically adjust the operating parameters of the water injection pump through the control system to ensure the water supply speed and the safety of equipment operation; finally, the water injection is completed, the water level of the large water pool reaches the set height, the control system turns off the water injection pump, and stops the water injection operation; The drainage process is as follows: in the initial state, the drainage valve 14 and the water injection valve 13 are closed, the outer reservoir 3 is not connected to the lower annular return corridor 5, the upper corridor 7 is connected to the bottom 1 of the large water pool and the lower annular return corridor 5, and the water level in the large water pool is monitored by the water pool level meter 8; then the drainage operation starts, the drainage valve 14 is opened, and the water flows from the bottom 1 of the large water pool through the upper corridor 7 and the lower annular return corridor 5 in turn through the action of gravity to flow back to the outer reservoir 3 and the inner reservoir 2; finally, the drainage is completed, the water level of the large water pool drops to the experimental set height, and the control system closes the drainage valve 14.

[0030] The injection and drainage pump room 6 of this embodiment has a redundant design. Each injection pump is equipped with an independent electric butterfly valve and gate valve to support the coordinated operation of multiple pumps. Even if a certain device fails, it can still guarantee the normal operation of other pumps, ensuring the stability and continuity of the experimental process. In addition, the scheduling process uses the control system to independently adjust the operating parameters of each injection pump based on the data collected in real time by the liquid level meter, so that in different experimental scenarios, each injection pump can flexibly and accurately adjust the operating state to meet the water level and water volume requirements of different experiments, greatly improving the flexibility and adjustability of the experiment to achieve the best scheduling effect. In addition, the drainage process uses gravity self-flow to return the water from the pool to the inner reservoir and the outer reservoir without additional energy consumption, avoiding the high energy consumption operation of the pump, thereby significantly reducing energy consumption and operating costs, while maintaining efficient operation while optimizing the energy use of the overall system.
