Problems solved by technology

[0004] In the prior art, a semi-automatic irrigation method is usually used when irrigating farmland, that is, water resources are extracted by using water pumps and water pipes, and then introduced into the farmland by combining one-way valves and water pipes for irrigation. In order to facilitate the start of the pump after a short-term stop, a bottom valve needs to be installed at the bottom of the water source pipe. During operation, once the bottom valve leaks water, the pump casing will overheat and the water temperature will rise, which will easily lead to expansion of the outlet pipe. Deformation, the sealing of the water pump will be destroyed; in addition, the pump needs to maintain a vacuum state in the pump casing during normal startup, so it is necessary to manually add water and exhaust before starting, which is not only cumbersome but also easy to be ignored. Once the staff forgets to add water, the pump will be damaged. Idling affects the service life of the water pump; and, the water pump is in an abnormal working state for a long time, which will lead to frequent maintenance and waste of cost

Embodiment 1

[0030] A water diversion device for diversion irrigation downstream of a flood outlet, such as figure 1 and figure 2 As shown, including the diversion dike 1 arranged downstream of the flood outlet along the river channel and the reinforcement plate I2 and reinforcement plate II3 arranged inside the diversion dike 1, the angle between the length direction of the reinforcement plate I2 and the reinforcement plate II3 and the water flow direction Both are 30-150 degrees. The bottoms of reinforcement plate I2 and reinforcement plate II3 are connected to the bottom of diversion dike 1 at an angle of 30-90 degrees, and the tops are respectively connected to the top of diversion dike 1. Reinforcement plate I2 and reinforcement plate II3 are A number of diversion tunnels I4 and II5 for the passage of water are opened respectively, and the diversion tunnels I4 and II5 are arranged in a staggered one-to-one correspondence. The side of the dike 1 facing the river bank is provided with ...

Embodiment 2

[0033] This embodiment is a further optimization of embodiment 1: as Figure 4 As shown, the facing surface of the diversion dike 1 is laid with an elastic cushion 15 to dissipate the energy of the water flow, reduce the impact force of the water flow on the diversion dike 1, and avoid impacting the diversion dike 1 when the water flow is too large, affecting the water diversion The service life of the embankment 1; the elastic cushion layer 15 is provided with a number of splash guards 16 located at different heights and parallel to each other along the arrangement direction of the diversion hole I7. The side of the splash guard 16 away from the elastic cushion layer 15 is inclined downward. To block the water flow and avoid the splash of water flow.

Embodiment 3

[0035] This embodiment is a further optimization of Embodiment 1: when the baffle 9 falls, the water flowing out of the flood outlet will impact the diversion dike 1 due to the barrier of the baffle 9. In order to reduce the impact force of the water flow, the diversion dike 1 The surface in contact with the water flow is set as an arc surface, such as figure 1 As shown, when the baffle plate 9 closes the diversion channel 8, the water flow blocked outside the baffle plate 9 flows downstream along the arc of the dike 1, which can not only play a guiding role, but also reduce the impact of the water flow. Extend the service life of dikes.

Abstract

The invention discloses a water diversion device used for diversion irrigation of the downstream of a flood discharge outlet. The water diversion device comprises a water diversion dike on the downstream of the flood discharge outlet along a riverway, a reinforcing plate I and a reinforcing plate II, wherein the reinforcing plate I and the reinforcing plate II are arranged in the water diversion dike, a plurality of flow guide holes I are formed in the reinforcing plate I, a plurality of flow guide holes II are formed in the reinforcing plate II, the number of the flow guide holes I is equal to that of the flow guide holes II, the flow guide holes I correspond to the flow guide holes II one to one, and the flow guide holes I and the flow guide holes II are staggered. A plurality of diversion holes II are formed in the face, towards a river bank, of the water diversion dike, a plurality of diversion holes I are formed in the upstream face, the diversion holes I are connected with the flow guide holes I, the flow guide holes II and the diversion holes II in sequence to form a plurality of diversion channels, baffles are arranged at the diversion holes I respectively, the tops of thebaffles are connected with a hoisting device on the top of the water diversion dike through steel wire ropes, and flow guide ditches are formed in the diversion holes II respectively. According to thewater diversion device, the water diversion dike is combined with the diversion channels, water flow is guided, water in the riverway flows into a farmland through the flow guide ditches to irrigatethe farmland, and the water diversion device is more convenient and efficient to use.

Description

technical field [0001] The invention relates to the technical field of water conservancy irrigation, in particular to a water diversion device for diversion irrigation downstream of a flood outlet. Background technique [0002] Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs, so some water conservancy projects need to be built to control water flow, regulate water flow and distribute it rationally. Make it applicable to human production and life. [0003] In human production and life, food is indispensable for human survival. Therefore, the existence and maintenance of farmland is extremely important. Therefore, in order to avoid the shortage of irrigation water in farmland, it is usually necessary to build irrigation water conservancy facilities to remove external Water is introduced into the fields for irrigation. [0004] In the prior art, a semi-automatic irrigation method is usually used ...
