Abstract
The utility model provides a weir case is used to current surveying, including the rectangle box, be located the crest of weir on box lateral wall upper portion and be located the valve that drains of bottom half, still including the first overhead spoiler that is located the box, down put spoiler, second overhead spoiler, pendulum leaf spoiler, flatly put the spoiler and flow back the board. The utility model discloses a set up first overhead spoiler, put the spoiler down, the spoiler is peacefully put to second overhead spoiler, can make rivers more steady, utilizes the pendulum leaf spoiler can regulated stream flow size and orientation, the water that utilizes the backward flow board can prevent the bottom half crest of weir of directly swarming, the swirl appears in the rivers of the crest of weir of avoiding flowing through, and the water flow data that messenger weir case is used to current surveying recorded is more accurate.
Description
Technical field
The utility model relates to water flow monitoring technical field of tools, particularly relates to a kind of flow measurement weir case.
Background technology
In water conservancy, hydrogeological industry, when earth's surface discharge is monitored, weir case can be set.Weir case generally refers to the casing being located in channel, tank and having special spilling breach, railway carriage or compartment, weir conventional at present, when discharge is large, can form obvious current vortex at spilling breach, cause the current by overflowing breach unstable, and then have influence on the accuracy of discharge Monitoring Data.Therefore, a kind of new flow measurement weir case of invention is needed to solve above-mentioned technical matters.
Summary of the invention
The technical matters that the utility model solves is to provide a kind of flow measurement weir case, and it has, and accuracy of measurement is high, structure simple, easy to use, the advantage that cost is low.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of flow measurement weir case, comprise rectangular box, be positioned at the crest of weir on wall box top and be positioned at the water drain valve of bottom half, open wide above casing, above casing without the side of crest of weir as water inlet, it is characterized in that: be provided with in described casing from water inlet side to be spaced successively to crest of weir side distribution first on put spoiler, underlying spoiler, spoiler is put on second, pendulum leaf spoiler, spoiler is put on described first, underlying spoiler, spoiler is put on second, pendulum leaf spoiler is vertical distribution and parallel with the wall box being provided with crest of weir,
Put on described first and spoiler, second puts spoiler and pendulum leaf spoiler is positioned at casing top, its top is parallel with above casing, is highly 3/1 to five/2nds of box height;
Described underlying spoiler is positioned at lower box, and it is parallel with below casing below, is highly 3/1 to five/2nds of box height;
The below of putting spoiler and pendulum leaf spoiler on second is provided with horizontal spoiler, horizontal spoiler connection second is put the base of spoiler and pendulum leaf spoiler and extends to the wall box being provided with crest of weir;
Put on described first on spoiler, underlying spoiler, second and put spoiler, horizontal spoiler is equipped with some holes;
Described pendulum leaf spoiler is made up of some vane plates that can swing, and can regulate current size and Orientation by adjustment vane plate angle.
As the further improvement of the technical program, be provided with a back flow plate below described horizontal spoiler, back flow plate is arranged on and is provided with on the wall box of crest of weir, and back flow plate is imperforate plate.
The utility model flow measurement weir case, puts spoiler and horizontal spoiler by arranging to put on spoiler, underlying spoiler, second on first, and current can be made more steady, utilizes pendulum leaf spoiler can regulate current size and Orientation; Utilize back flow plate can prevent the water of bottom half from directly swarming crest of weir, avoid the current flowing through crest of weir to occur vortex, the water flow data that flow measurement weir case is recorded is more accurate.
Accompanying drawing explanation
Fig. 1 is the perspective view of flow measurement weir described in the utility model case.
Fig. 2 is the A-A cross-sectional schematic of flow measurement weir described in the utility model case.
Component names corresponding in figure is: 1 casing, 2 crests of weir, 3 water drain valves, 4 water inlets, 5 first are put on spoiler, 6 underlying spoilers, 7 second and put spoiler, 8 pendulum leaf spoilers, 9 horizontal spoilers, 10 back flow plates.
Embodiment
Refer to shown in Fig. 1 and Fig. 2, the utility model provides a kind of flow measurement weir case, comprises rectangular box 1, is positioned at the crest of weir 2 on wall box top and is positioned at the water drain valve 3 of bottom half.Crest of weir 2, as water export, can be set to the various shape such as triangle, trapezoidal rectangle according to measurement needs.Open wide above casing, above casing without the side of crest of weir as water inlet 4, be provided with in described casing from water inlet 4 side to be spaced successively to crest of weir 3 side distribution first on put on spoiler 5, underlying spoiler 6, second and put spoiler 7, pendulum leaf spoiler 8, put on described first on spoiler 5, underlying spoiler 6, second and put spoiler 7, pendulum leaf spoiler 8 is vertical distribution and parallel with the wall box being provided with crest of weir; Put on described first and spoiler, second puts spoiler and pendulum leaf spoiler is positioned at casing top, its top is parallel with above casing, is highly 3/1 to five/2nds of box height; Described underlying spoiler is positioned at lower box, and it is parallel with below casing below, is highly 3/1 to five/2nds of box height.Spoiler is put and underlying spoiler is interspersed in the design, the below of putting spoiler and pendulum leaf spoiler on second is provided with horizontal spoiler 9, horizontal spoiler connection second is put the base of spoiler and pendulum leaf spoiler and extends to the wall box being provided with crest of weir; Put on described first on spoiler, underlying spoiler, second and put spoiler, horizontal spoiler is equipped with some holes; Current can be made to become more steady by above-mentioned design.
Described pendulum leaf spoiler is made up of some vane plates that can swing, and can regulate current size and Orientation by adjustment vane plate angle; Be provided with a back flow plate 10 below horizontal spoiler, back flow plate is arranged on and is provided with on the wall box of crest of weir, and back flow plate is imperforate plate.Back flow plate can prevent the water of bottom half from directly swarming crest of weir, and current flow out from crest of weir stably through pendulum leaf spoiler after repeatedly turning to, shunting, and the water flow data that flow measurement weir case is recorded is more accurate.
The above; it is only most preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; any those of ordinary skill in the art; do not departing under technical solutions of the utility model ambit; utilize the method content of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, all belong to the scope of claims protection.
