21, so that overflow weir 21 is hanging and has certain height apart from settling pit bottom 3, the overflow weir 21 item small in the big one end in one end
Shape body or column form overflow ducts 22 between two neighboring overflow weir 21, since the side of the overflow weir 21 is respectively provided with
At zigzag, increase the effective length of overflow weir 21 on the basis of original space so that in overflow ducts 22 water flow it is effective
Process is elongated, stationary flow flow velocity, and the further deposit efficiency for improving settling pit, the small end of the baffle 23, which is located at, to be leaned on
Nearly water outlet end, the rear of small end, that is, baffle 23 of the baffle 23 are equipped with vortex groove 24, and the vortex groove 24 is in slot
Shape body is simultaneously embedded in settling pit bottom 3, and the vortex groove 24 is equipped with sediment ejection opening 27, and sediment ejection opening 27 is located at the outside of pond body B2, described
Vortex groove 24 is vertical with water (flow) direction, and the radial direction of the vortex groove 24 is in a horizontal state with settling pit bottom 3 or the vortex
The horizontal position of 27 one end of sediment ejection opening of slot 24 is lower than the other end, i.e., is between the radial direction of vortex groove 24 and settling pit bottom 3
Certain angle makes vortex groove 24 that inclined state be presented, and is more advantageous to silt in this way and flows to sediment ejection opening 27, the sediment ejection opening 27
Place is equipped with control valve 26, when sand reaches a certain level in vortex groove 24, opens control valve, washes away desilting.
In actual use, it needs the water flow of desilting to flow into pond body A1 from water inlet, is acted on by the energy dissipating of adjusting-flow board 11,
It is layered the silt in water flow, the tune discharge orifice 12 of 11 bottom of adjusting-flow board can be effectively prevented from the whirlpool of 11 back side of adjusting-flow board generation
Stream and sand phenomenon, according to hydrodynamics and hydraulic principle, since adjusting-flow board 11 is sequentially reduced from front to back, after avoiding
Continuous water flow generates disorder phenomenon, influences deposit efficiency, interior in a limited space since adjusting-flow board 11 is staggered in splayed
Active length is significantly increased, more uniformly, is steadily imitated with low speed, the effective desilting that improves by the water flow of pond body A1
Rate, the water flow pond body B2 after pond body A1 for the first time desilting, water flow are stopped to overflow from overflow ducts 22 by baffle 23, and due to
The side of overflow weir 21 is serrated, so that effective process of water flow is elongated in overflow ducts 22, and due to overflow weir 21
Horizontal position is higher than settling pit bottom 3, and part silt can slowly deposit to bottom of pond, and the silt content in spill stream is reduced by, from
And the more clear water in surface is obtained, it flows down and enters in vortex groove 24 from the inclined-plane of baffle 23 by the water flow of overflow weir 21, by
It is acted in the potential energy of baffle 23, can be realized vortex centrifugal effect into the water flow in vortex groove 24, to reach secondary desilting
Purpose, deposit efficiency is higher.Desilting rate is improved, the water flow that the baffle 25 that 24 rear portion of vortex groove is equipped with goes out overflow passes through as far as possible
Baffle 25 is again introduced into vortex groove 24, is removed sand using eccentricity principle, and when extending vortex of the water flow in vortex groove 24
Between, water velocity is reduced, the disorder phenomenon of water flow is reduced, to achieve the purpose that secondary desilting, deposit efficiency are higher.
Embodiment 2: compared with Example 1, the present embodiment the difference is that, the size of the adjusting-flow board 11 is by going to
After be sequentially reduced, can reduce the water flow disorder phenomenon of settling pit below.
Embodiment 3: being the structural schematic diagram of the utility model embodiment 3 referring to Fig. 7, compared with embodiment 1 or 2, this reality
Apply example the difference is that, the vortex groove 24 is a certain included angle with water (flow) direction, and the radial direction of the vortex groove 24 with
Settling pit bottom 3 is in a horizontal state or the horizontal position of 27 one end of sediment ejection opening of the vortex groove 24 is lower than the other end, that is, is vortexed
It is at an angle between the radial direction and settling pit bottom 3 of slot 24 to make vortex groove 24 that inclined state be presented, it is more advantageous in this way
Sediment ejection opening 27 is flowed in silt, one side that the vortex groove 24 is open is concordant with the contact surface at settling pit bottom 3 with baffle 23, separately
The edge on one side is equipped with baffle 25, and the height of the baffle 25 is selected according to the actual situation, the water in vortex groove 24
Stream can be stopped to be again introduced into vortex groove 24 to generate multiple eddy current effect after vortex by the baffle 25, the baffle
25 can promote vortex efficiency, so that vortex phenomenon extends, to improve sand discharge rate and desilting rate.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, without departing from the concept of the present invention, several changes and improvements can also be made, these all belong to
In the protection scope of the utility model.
