[0003] Due to the importance of aqueduct, the characteristics of particularly large construction quantity and wide coverage, the safe and reliable operation of aqueduct is particularly important.

[0004] After laying aqueduct, initial water inflow or external water, especially sudden water inflow, etc. can cause sudden fluctuation of water flow in aqueduct, and sudden water inflow can impact aqueduct, especially causing damage to connection or connecting parts and connecting joints in aqueduct, resulting in leakage and increasing maintenance cost. SUMMARY

[0005] The utility model aims at overcoming the insecurity problem caused by water impact due to external water inflow of existing aqueduct, and realizes protection of aqueduct and reduction of maintenance cost.

DETAILED DESCRIPTION

[0013] In order to further illustrate the technical means and effects taken by the utility model to achieve the predetermined purpose, the specific implementation, structural features and effects of the utility model are described below in combination with the drawings and examples as follows.

[0014] In order to solve the problem that the existing aqueduct will cause sudden fluctuation of water flow in the aqueduct, sudden water surge will impact the aqueduct, especially will cause damage to the connection or connecting parts and connecting joints in the aqueduct, form gaps and cause leakage, and increase maintenance cost when initial water inflow or water from outside the channel (such as mountain stream rising water, plum rain season flood, etc.) especially sudden water surge occurs, the embodiment provides an aqueduct with water energy buffer self-protection. Figure 1 The aqueduct with water energy buffer self-protection shown in the figure comprises a trough body 1 and a flow distribution groove outside the trough body (this is an existing structure, part of the section is assembled with a flow distribution groove, mainly used for irrigation distribution), at least one transversely mounted flow suppression frame 2 is arranged in the trough body 1, a plurality of guide plate layers arranged from bottom to top are arranged on the flow suppression frame 2 in the height direction, a plurality of eccentric guide plates 3 are arranged on each guide plate layer in the transverse direction, the bottom surface or side surface of the eccentric guide plate 3 is sleeved on the support rod 4 of the guide plate layer, and the center of gravity of the eccentric guide plate 3 is away from the support rod 4, so that the eccentric guide plate 3 is inclined downward toward the water inflow direction; the support rod 4 is arranged in the transverse direction. In this way, when a torrent enters the aqueduct, the eccentric guide plate 3 guides the water flow, blocks the water flow at the same time, lifts and guides out from the rear end of the eccentric guide plate 3, in this way, an upward pick-up flow channel is formed, which can provide a pick-up flow mode, effectively eliminate the kinetic energy of the water flow, weaken the scouring effect of the incoming water, and eliminate the kinetic energy of the water flow after pick-up flow, thereby protecting the safety of the aqueduct.

[0015] In order to enhance the buffering effect on the kinetic energy of the water flow, the eccentric guide plates 3 in the adjacent guide plate layers are arranged in a staggered and overlapping manner in the embodiment, forming an interlocking of the upper and lower eccentric guide plates, generating a segmented resistance to the water flow, and effectively weakening the kinetic energy of the water flow.

[0016] At the same time, two of the flow suppression frames 2 are arranged in parallel along the axial direction of the trough body 1, which can better realize the secondary weakening of the kinetic energy of the water flow.

[0017] In order to facilitate installation and later maintenance, the transverse two ends of the flow suppression frame 2 are arc-shaped with the same curvature as the inner wall curvature of the trough body 1, and the two ends of the flow suppression frame 2 are respectively clamped in the arc-shaped limiting grooves on the inner wall of the trough body 1.

[0018] In order to buffer the kinetic energy of the torrent before it enters, the embodiment is characterized in that Figure 2 The water flow control member is provided at the inlet of the trough body 1 and is composed of a flow guide groove 6 fixed transversely on the top of the trough body 1 and a plurality of flow control ladders 7 arranged in parallel transversely in the trough body 1; the flow guide groove 6 is provided with a flow guide plate 9 extending into a flow distribution groove 8 outside the trough body 1 at both ends thereof, so as to guide the water entering the flow guide groove 6 through the flow control ladders 7 into the flow distribution groove 8; the flow control ladder 7 is composed of a triangular support plate 10 and a plurality of flow control guide plates 11 stacked from bottom to top along the inclined surface of the triangular support plate 10; the lower end of the upper flow control guide plate 11 is stacked below the upper end of the adjacent lower flow control guide plate 11; the two sides of the flow control guide plate 11 are fixed in the installation groove 12 of the inclined surface through a pin shaft, so that the flow control guide plate 11 can swing with the water flow within a certain range, which can not only block and guide the water flow, but also slow down the damage of the water flow to the flow control guide plate 11.

[0019] Through the above measures, the kinetic energy of the torrent entering the trough body is effectively slowed down, the trough body is protected from the destructive scouring of the torrent, the maintenance cost is greatly reduced, and the safety and reliability of the aqueduct are improved.

[0020] The above is a further detailed description of the utility model in combination with specific preferred embodiments; the specific implementation of the utility model cannot be limited to these descriptions.
