Inside is in the steel-slag sand of hollow structure.Specifically, the inside of the tube-like piece 70 tool hollow structure, such as tube-like piece 70 can use nothing
Seam steel pipe is made, and plate-like piece 71 can use thickness to be made up of 1~30mm steel plate.
In order to further increase the structural strength of checkdam panel 1, in the present embodiment, in plate-like piece 71 and tube-like piece
70 intensive can also have additional floor 4 and floor 3 near the both ends end of transverse direction.Wherein, the distance between floor 4 and floor 3
Need to be significantly less than the spacing between spacing and floor 6 and the floor 4 between multiple floors 6 in housing 11.In addition, housing
The equally arrangement between multiple floors 6 in 11.
With reference to shown in Fig. 5, in the present embodiment, the checkdam panel 1 is provided with partial receipt drag link mechanism in back side
And be in some depressed parts 12 of open state, two reinforcing plates 410 longitudinally disposed and in strip are provided with each depressed part 12,
One end of the reinforcing plate 410 is rotatablely connected floor 6 by the 3rd lever 409, and the other end of the reinforcing plate 410 is by tube-like piece
70 extend transversely through and are in integral structure with floor 6.Reinforcing plate 410 is set in parallel with multiple floors 6, and and water (flow) direction
It is arranged in parallel.Reinforcing plate 410 extends transversely through two tube-like pieces 70, and tube-like piece 70 connects with two adjacent floors 6 in rigidity
Connect, so as to drive checkdam panel 1 to be pivoted around rotary shaft 2 by the rotation of the lever 409 of rotatable lamella 403 and the 3rd, collaboration
Motion.
When active blocking dam is in raised state, the angle of the plate-like piece 71 and horizontal plane is -30 degree to+30 degree,
Further, when active blocking dam is in raised state, the angle of the plate-like piece 71 and horizontal plane is 0 degree.By this
Mode, it may be such that skeleton has higher structural strength, significantly improve the structural strength of checkdam panel 1, especially can
The transversary intensity of checkdam panel 1 is significantly improved, and effectively prevent checkdam panel 1 and become in the presence of hydraulic pressure
The problem of shape and leak.
It should be noted that the rotatable lamella 403 is not necessarily defined to triangle, such as rotatable lamella can be also configured to parallel
Quadrangle, rhombus, trapezoidal or other irregular shapes.Top and the second lever 402 due to the push rod 444 of hydraulic jack 40
It is fixedly connected, therefore in push rod 444 during elongation or shortening, the first lever 404 and the second lever 402 and the 3rd lever
The 409 i.e. achievable above-mentioned effects of dislocation arrangement on floor projection direction, meanwhile, on floor projection direction, the first lever 404
It is located at the both sides of the second lever 402 respectively with the 3rd lever 409.Preferably, in the present embodiment, first lever 404 with
The distance between second lever 402 is less than the distance between the second lever 402 and the 3rd lever 409.In this way, can be with
So that the push rod 444 of hydraulic jack 40 can drive the 3rd lever 409 to complete swing by a relatively large margin under less stroke, from
And drive the pivoting action of checkdam panel 1.
In the present embodiment, two hydraulic jacks 40 are provided with each checkdam unit, and in each hydraulic jack
40 both sides are symmetrical arranged two compensation linkages, therefore, by rotating each pull bar 406, to adjust each checkdam unit
With the angle in base dam crest portion, and cause the active blocking dam that is spliced side by side Ji Ba tools uneven to bottom or unhorizontal
There is more preferable adaptability.By setting compensation linkage, and by adjusting the longitudinal length of the compensation linkage, with to dash
The angle of dam facing plate 1 and horizontal plane is finely adjusted, it is achieved thereby that to maximum angle of the checkdam unit when lifting and lodging
When minimum angles be adjusted, to realize to the flexible modulation of the active blocking dam reservoir storage, solve movable dash
Dam in checkdam unit sidepiece and bottom caused by out-of-flatness existing for base foundation occurring the problem of leak, significantly carrying
The high water storage effect of the active blocking dam.
Herein described maximum angle when lifting refers to, checkdam panel 1 is when lifting to maximum angle and horizontal plane
The maximum angle formed；The minimum angles during lodging refer to, checkdam panel 1 is when the limit arrive in lodging and horizontal plane institute
The minimum angle of formation.
