Abstract

The invention provides a combined pump and gate system suitable for irrigation in dry and rainy seasons. This technical solution uses a vertical submersible pump, and its outlet is opened above the highest water level, so that it can not only discharge the river water to the irrigation channel for irrigation in the dry season, but also realize the function of the gate in the rainy season to prevent flood disasters. Moreover, the vertical installation structure has technical advantages such as small footprint and high concentricity. At the same time, the present invention uses the outlet pipeline to directly guide the water flow below the water level of the irrigation channel, which can avoid the noise of falling water caused by the water outlet being higher than the water level of the irrigation channel; on this basis, a vacuum breaker valve is installed on the pipeline, Prevent the siphon effect formed when the pump is stopped in the rainy season. In addition, the vertical installation usually adopts the form of the outlet vertically downward or the elbow, and the vortex is easy to form at the outlet during the operation of the pump; Effectively prevent vortex and improve pump performance.

Description

technical field [0001] The invention relates to the technical field of irrigation equipment, in particular to a pump gate combination system suitable for irrigation in dry and rainy seasons. Background technique [0002] The pump-gate combination system is a new structure that installs the submersible pump on the gate. In some areas with distinct dry and rainy seasons, the traditional pump-sluice combination system can only perform the function of irrigation in the dry season, but cannot play the role of flood control in the rainy season. figure 1 It shows the structure of the traditional pump-sluice combination system. In the dry season, the submersible pump will forcefully drain the water from the river to the irrigation channel, and the gate will prevent the river from flowing back. However, when the rainy season comes, the water level of the river is higher than that of the irrigation channel. Flooding will be caused from flapping artesian flow to irrigation channels. ...
