It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined in a figure, further discussion thereof is not required in subsequent figures.
Referring to fig. 1 and 2, the first embodiment of the present invention is schematically illustrated. As shown in fig. 1, the hydraulic engineering dam structure mainly comprises a dam body 11, a channel 12, a portal frame 13, a swing arm 14, an arc baffle 15, an arc groove 16, a driving device and the like, wherein the dam body 11 is made of concrete and is directly built on a river channel, and the channel 12 is located on the dam body 11 and used for draining water. The portal frame 13 is composed of two vertical beams and a cross beam, wherein the two vertical beams are fixed on the dam body 11 and are respectively located at two sides of the channel 12, and two ends of the cross beam are respectively fixedly connected with the two vertical beams and are located right above the channel 12.
The number of the swing arms 14 is two, and the swing arms are respectively hinged on two vertical beams of the portal frame 13 and can freely swing; the arc-shaped baffle 15 is fixedly connected to the swing arm 14 and can freely swing along with the swing arm 14. An arc-shaped groove 16 is formed in the bottom surface of the channel 12, and the curvature radius of the arc-shaped groove 16 is equal to that of the arc-shaped baffle 15, that is, the arc-shaped baffle 15 can smoothly slide into the arc-shaped groove 16.
Referring to fig. 4, the driving device is composed of a bracket 21, a rotating shaft 22, a winding drum 23, a wire rope 24 and a power device 25, wherein the bracket 21 is placed on the dam body 11, and both ends of the rotating shaft 22 are inserted into holes or bearing seats on the bracket 21 and can rotate freely under the action of external force. The drum 23 is fixedly connected to the shaft 22 and can rotate therewith. One end of the wire rope 24 is fixedly connected to the winding drum 23, the middle part is wound on the winding drum 23, and the other end is fixedly connected to the swing arm 14. The power device 25 is composed of a motor and a speed reducer, an output shaft of the speed reducer is connected with the rotating shaft 22 in a coupling, belt transmission or gear transmission mode, so that when the motor outputs power, the rotating shaft 22 and the winding drum 23 can be driven to rotate through the speed reducer, the winding drum 23 can pull the steel wire rope 24 to move together when rotating, and the swing arm 14 and the arc-shaped baffle plate 15 can shake together.
Referring back to fig. 1, in order to enable the arc baffle 15 to be stable after being opened or closed, a positioning blind hole 31 needs to be formed in the dam body 11, a positioning column 32 is placed in the positioning blind hole 31, and the number of the positioning blind holes 31 is multiple and is respectively located at positions where the lantern rings 33 are located on the steel wire rope 24 when the arc baffle 15 is at different positions. Therefore, after the arc-shaped baffle 15 is moved to a position, the corresponding positioning column 32 can be pulled out from the positioning blind hole 31 and inserted into the corresponding positioning blind hole 31 after being inserted into the lantern ring 33.
Referring to fig. 3, the dam 11 is further provided with a longitudinal channel 41 and a transverse channel 42, wherein the transverse channel 42 is located right below the arc-shaped groove 16 and is communicated with the arc-shaped groove 16 through a plurality of channels, one end of the longitudinal channel 41 is communicated with the transverse channel 42, and the other end is communicated with the upper surface of the dam 11. The waste settled in the arc-shaped chute 16 can thus fall into the transverse channel 42 and be cleaned from the longitudinal channel 41.
For the sake of safety, a protective net 5 is added at the connection part of the longitudinal channel 41 and the dam, one end of the protective net 5 is hinged on the dam 11, and the other three sides are all lapped on the dam 11, so that the protective net 5 can cover the whole connection part.
The implementation principle of the embodiment is as follows:
under normal conditions, cowl 15 is in the closed condition, and rubbish in the river course can be along with water slow flow this moment, stops after striking cowl 15, then deposits gradually in the arc wall 16 on passageway 12 bottom surface.
With the increase of the service time, the more the garbage in the arc-shaped groove 16 is accumulated, and correspondingly, the more the garbage in the transverse channel 42 is, at this time, the garbage needs to be cleaned, and the specific cleaning process is as follows:
and (3) opening the protective net 5 on the dam body 11, inserting the extraction equipment into the longitudinal channel 41 and starting, extracting the garbage in the transverse channel 42, enabling the water in the channel 12 to flow along with the garbage, flushing the channel 12 and the transverse channel 42, and after cleaning is finished, withdrawing the extraction equipment and loading the protective net 5 back. The principle of the extraction apparatus is similar to that of the sand suction apparatus, since the major part of the sludge that settles into the arc chute 18 is sludge, and can therefore be extracted using the extraction apparatus.
When discharging water, the arc-shaped baffle 15 is generally rotated in a direction close to the bottom surface of the channel 12, and water flows over the arc-shaped baffle 15. The advantage of this drainage mode is that the running water does not affect the settled waste and the discharged water is essentially clear water.
When the maintenance operation, cowl 15 rotates to the direction of keeping away from passageway 12 bottom surface, appears a gap between cowl 15 and the passageway 12 bottom surface this moment, and under the effect of pressure, rivers flow from this gap with higher speed, and the rivers that flow at a high speed can be washed away near the region, and rubbish etc. that will deposit are washed away.
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.
