Embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this instructions can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1 to Fig. 2.Notice, structure, ratio, size etc. that this instructions institute accompanying drawings illustrates, content all only in order to coordinate instructions to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop in scope that technology contents that the utility model discloses can contain.Simultaneously, quote in this instructions as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of mounting structure of thin-walled weir, mainly comprises water gauge 3, and the upstream weir notch 1 be connected successively by water (flow) direction and downstream weir notch 2, and described water gauge 3 is located in upstream weir notch 1; Particularly, described water gauge 3 is arranged on the inside sidewalls of described upstream weir notch 1.Described upstream weir notch 1 and downstream weir notch 2 connecting place are provided with weir plate 6; The bottom land of described upstream weir notch 1 and the bottom land of described downstream weir notch 2 are positioned in same level; Described upstream weir notch 1 water inlet is connected by slope 5 with trench drain 4, and described upstream weir notch 1 water inlet is connected with described slope 5 low side; Described downstream weir notch 2 freeing port is connected with sump 7.
Be provided with baffle wall style 8 and breastwork 9 in described upstream weir notch 1, and described baffle wall style 8 and breastwork 9 are all positioned at described water gauge 3 upstream.In order to slow down the surface wave of current, to obtain the stable liquid level being convenient to measure, and then the measurement accuracy of increasing amount mill weir, described baffle wall style 8 is arranged on described breastwork 9 upstream, sees Fig. 1 and Fig. 2.
Described baffle wall style 8 apical side height is consistent with described weir plate 6 indentations bottom height, like this can either fully energy dissipating again can not raising of water level, sees Fig. 2.
The bottom of described breastwork 9 is lower than described weir plate 6 top, and the bottom of described breastwork 9 is higher than described weir plate 6 indentations bottom; When current pass through, the surface wave that described breastwork 9 can slow down current does not hinder current again, sees Fig. 2.
The degree of depth of described upstream and downstream weir notch 2 is consistent with the height of weir plate 6, like this when weir full scale, also can not be formed in trench drain 4 and choke water, see Fig. 2.
