Attached Figure Description

[0015] Figure 1 This is a schematic diagram of a water hammer pump system that can realize staged pumping and energy storage.

[0016] Figure 2 This is a rendering of a water hammer pump system that can achieve staged pumping and energy storage. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-2As shown, a water hammer pump system capable of staged pumping and energy storage includes a top reservoir 1 located at the uppermost level. The outlet of the reservoir 1 is connected to the upstream of a flow channel 2, and the downstream of the flow channel 2 is connected to the inlet of a turbine generator set 3. Multiple water channels 4 are provided at different heights below the top reservoir 1. Each water channel 4 is connected to the inlet of a water hammer pump 6 through a water inlet pipe 5. The outlet of the water hammer pump 6 is connected to the upstream water channel 4 through a water delivery pipe 7. The water hammer pump 6 located at the uppermost level is connected to the reservoir 1 through the water delivery pipe 7. In this embodiment, the water inlet pipe 5 (generally inclined, resulting in a height difference) introduces water from the water channel 4 into the water hammer pump 6. The water flow generates a water hammer effect in the water hammer pump 6, causing the water hammer pump 6 to operate and pump water. This allows water in the downstream water channel 4 to be pumped to the upstream water channel 4, and finally pumped into the reservoir 1 for storage. The water in the reservoir 1 then enters the inlet of the turbine generator set 3 through the flow channel 2, thereby enabling the turbine generator set 3 to operate and generate electricity, thus improving the energy utilization efficiency of the entire system.

[0019] Preferably, regulating pipes 8 are also provided between each water channel 4 and between the upstreammost water channel 4 and the reservoir 1, and control valves 9 are provided on the regulating pipes 8. In this embodiment, as... Figure 2 As shown, each irrigation canal 4 has terraced fields on its sides, which facilitates irrigation of the plants within the terraces. However, due to the influence of the geographical environment, the water levels in each irrigation canal 4 vary. When the water level in a certain irrigation canal 4 is too shallow, water from the deeper irrigation canals 4 can be introduced into that irrigation canal 4 through the regulating pipe 8. When the water levels in all irrigation canals 4 are too shallow, water from the reservoir 1 can be introduced into the upstream irrigation canal 4 through the regulating pipe 8, and then sequentially introduced into the other irrigation canals through the regulating pipe 8, ultimately achieving a balanced distribution of water resources.

[0020] Preferably, each water channel 4 is also equipped with a water level sensor 10. The water level sensor 10 can monitor the water level in each water channel 4 in real time, facilitating intelligent monitoring and adjustment.

[0021] Preferably, the water level sensor 10 is connected to the input terminal of the PLC controller, and the control signal output terminal of the PLC controller is connected to the control valve 9. Based on the water level information fed back by the water level sensor 10, when the water level in a certain water channel 4 is too shallow, the PLC controller can cause the control valve 9 of the corresponding regulating pipeline 8 to open, thereby realizing the intelligent regulation of the water level in each water channel.

[0022] Preferably, each water channel 4 is also equipped with a liftable gate 11, the drive control terminal of which is connected to a PLC controller. During the operation of the water hammer pump 6, if the water level in a certain water channel 4 is too low, the water flow into the water inlet pipe 5 will also be too small, which may cause the water hammer pump 6 to fail to work. At this time, the drive mechanism of the gate 11 can be controlled by the PLC controller to make the gate 11 fall and cut off the water flow in that water channel 4. As the water flow continues to flow in, the water level in the water channel 4 rises continuously, which increases the water flow into the water inlet pipe 5, thereby enabling the water hammer pump 6 to work normally.

[0023] Preferably, the gate 11 is slidably fitted with the groove of the gate frame, the top of the gate 11 is connected to the lower end of the traction rope, the upper end of the traction rope passes over the fixed pulley and is connected to the winch drum of the winch, the control terminal of the winch is connected to the PLC controller, the fixed pulley and the winch are both mounted above the gate frame through a support frame, and the gate frame is fixedly mounted on the water channel 4. In this embodiment, the winch drives the traction rope to move, thereby pulling the gate 11 up or releasing the rope to make the gate 11 fall.

[0024] Preferably, the water storage tank 1 is also connected to the irrigation system of the vegetable greenhouse 13 via a water delivery pipe 12. With this design, water from the water storage tank 1 can be transported over a long distance to the area where the greenhouse 13 is located via the delivery pipe 12, thereby carrying out sprinkler irrigation on the plants in the greenhouse and effectively utilizing the water resources in the water storage tank 1.

[0025] Preferably, the lighting system of the vegetable greenhouse 13 is connected to the power output terminal of the hydro-generator set 3 via a power transmission line 14. This design allows the power from the hydro-generator set 3 to power the lighting system within the vegetable greenhouse 13.

[0026] Preferably, multiple irrigation canals 4 are located within multiple terraced fields, with a certain height between each terraced field.

[0027] The working principle of this embodiment is as follows:

[0028] The water hammer pump 6 is an advanced water lifting device that uses flowing water as power and generates a water hammer effect through mechanical action, converting low head energy into high head energy. This invention introduces water from the canal 4 through the water inlet pipe 5 into the water hammer pump 6. The water flow generates a water hammer effect within the pump 6, causing it to operate and pump water. This pumps water from the downstream canal 4 to the upstream canal 4, and finally to the reservoir 1 for storage. The water in the reservoir 1 can be transported over a long distance to the area of ​​the greenhouse 13 via the delivery pipe 12, allowing for sprinkler irrigation of the plants and effectively utilizing the water resources in the reservoir 1. Additionally, the water in the reservoir 1 enters the inlet of the turbine generator set 3 through the flow channel 2, enabling the turbine generator set 3 to generate electricity, thus improving the overall energy efficiency of the system.

[0029] The above process enables multi-stage water lifting without external energy input, effectively solving irrigation problems in complex terrain areas such as mountainous regions, terraced fields, and arid areas. Simultaneously, the system integrates a hydro-turbine generator unit 3 on one side of the upstream reservoir 1, which converts the energy generated by the water hammer effect into electrical energy, further improving energy utilization efficiency. Actual measurements show that 15%-22% of potential energy loss can be recovered, increasing the system's overall energy utilization rate to over 78%, achieving cascaded energy utilization and efficient conversion. Furthermore, reservoir 1 stores excess water resources during the wet season for use during the dry season, further enhancing the system's stability and reliability.

[0030] From an economic and environmental perspective, the system engineering cost of this invention is reduced by 40%-60% compared to traditional solutions, significantly reducing construction investment. It also reduces reliance on non-renewable energy sources, lowers carbon emissions, and aligns with sustainable development requirements. The power generation module generates electricity during peak grid periods, generating additional revenue and further enhancing the system's economic efficiency, achieving a win-win situation for both economic and environmental benefits.

[0031] The staged pumping and energy storage water hammer pump system, with its efficient and energy-saving water resource lifting and distribution functions, flexible modular structural design, intelligent control logic, and significant economic and environmental benefits, demonstrates great application potential and promotion value, providing an innovative and effective solution for solving irrigation problems in complex terrain areas.

[0032] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
