Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, a low-cost water supply and drainage pump station, including two irrigation canals and ditches 3 of intercommunication inland river 1 and foreign river 2, every irrigation canals and ditches 3 links to each other with the mutual close node of inland river 1 and foreign river 2 to make irrigation canals and ditches 3's length less, and then practice thrift construction cost.

Each ditch 3 is provided with a gate 31, when the difference of water level occurs between the inland river 1 and the foreign river 2, the gate 31 is opened, the inland river 1 and the foreign river 2 are communicated through the ditch 3, and water flows from a river with high water level to a river with low water level.

Specifically, since the water level change of the inland river 2 is generally small, the difference between the water levels of the inland river 1 and the inland river 2 is generally generated due to the rising and falling of the water level of the inland river 1. During long-term drought, the water level of the inland river 1 is reduced and is obviously lower than the water level of the inland river 2, and at the moment, the gate 31 in the ditch 3 is opened, so that water in the inland river 2 flows into the inland river 1 along the ditch 3 to supplement the water quantity of the inland river 1, and people can conveniently take water and use water in the inland river 1; when long-term rainfall occurs, the water level of the inland river 1 can rise and is obviously higher than the water level of the inland river 2, the gate 31 in the ditch 3 is opened at the moment, the water of the inland river 1 can flow to the inland river 2 along the ditch 3, so that the water quantity of the inland river 1 is reduced, the situation that the periphery of the inland river 1 is damaged due to overhigh water level of the inland river 1 is avoided, and one or two ditches 3 can be selected to be opened for drainage according to the high degree of the water level of the inland river 1.

The hydroelectric generator 32 is arranged in each ditch 3, and the hydroelectric generator 32 can generate electricity when water flows through the ditches 3, so that water resources are more fully utilized.

Referring to fig. 1 and 2, a pipeline 4 communicating the two ditches 3 is arranged between two closest points of the two ditches 3, the pipeline 4 is dug under the ground and is lower than the bottom of the ditches 3, a water pump 5 is arranged in the pipeline 4, and the water pump 5 can pump water from the ditches 3 through the pipeline 4.

The gates 31 in each of the trenches 3 are provided in two at both ends of the pipe 4, respectively.

The water pump 5 is mainly arranged for discharging water of the inland river 1 as soon as possible when the water level of the inland river 1 is too high, when flood disasters happen when the water level of the inland river 1 is too high, the water of the inland river 1 naturally flows to the foreign river 2 through the ditches 3 by means of the liquid level difference between the water flows, flood discharge requirements cannot be met, at the moment, two gates 31 in each ditch 3 are opened and closed, the two opened gates 31 on the two ditches 3 are located on two sides of the pipeline 4, the water pump 5 is started to enable the water flows to flow through one part of the two ditches 3 and the pipeline 4, and the flow velocity of the water flows in the ditches 3 is larger than the natural flow velocity of the water flows generated due to the liquid level difference through the suction force of the water pump 5, so that the purpose of rapid.

The height of the pipeline 4 is lower than that of the bottom of the ditch 3, and under the condition that water exists in the ditch 3, the water in the pipeline 4 is always in an overflow state, so that the water delivery efficiency of the water pump 5 is maximized.

Referring to fig. 1, the water pump 5 is driven by a motor (not shown), the motor is set as a servo motor, and the motor is coupled with a control mechanism 7 for changing the rotating speed and direction of the motor, so that the water pump 5 can be adapted to different situations by changing the rotating speed and direction of the motor to change the pumping speed and direction of the water pump 5.

Be provided with the water level monitoring device of monitoring inland river 1 water level in inland river 1, water level detection device 6 can detect inland river 1 water level and feed back the staff with the signal to in the staff judges the inland river 1 water level condition. Meanwhile, the water level detection device 6 and the gate 31 are both coupled to the control mechanism 7, and the control mechanism 7 automatically controls the gate 31 and the water pump 5 to operate according to the water level signal fed back by the water level detection device 6, so as to prevent the workers from misjudging or failing to make correct actions in time to delay the disaster relief time.

Furthermore, the end parts of the ditches 3 connected with the inland rivers 1 and the foreign rivers 2 are widened, so that the possibility that the end parts of the ditches 3 are washed by water flow of the inland rivers 1 or the foreign rivers 2 is reduced.

Furthermore, the hydroelectric generator 32 is arranged in the ditch 3 near the end of the pipeline 4, so that when the water pump 5 is started, the hydroelectric generator 32 can also absorb part of the power provided by the water pump 5 for water flow, so as to achieve more full utilization of water resources.

According to the process, the pipeline 4 is only communicated with the two ditches 3, so that the length of the pipeline 4 is greatly reduced compared with the traditional pipeline 4 for communicating the inland river 1 and the foreign river 2, and the industrial cost is reduced.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
