Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, embodiments of the utility model; all other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The following describes in further detail the embodiments of the present utility model with reference to the accompanying drawings: the low water level flow measuring device for the U-shaped drain pipe comprises a water baffle 1, a flow rate sensor 3, a drain pipe 5 and a connecting rod 6, wherein the water baffle 1 is of a flat plate structure, a drain hole 2 is arranged at the lower end of the water baffle 1, and the drain hole 2 is a rectangular through hole; in the practical application process, the drain hole 2 is arranged at the lower end of the water baffle 1, the size of the drain hole 2 is set according to the practical use environment, when the water flow speed is relatively high, the drain hole 2 is larger, and when the water flow is relatively small, the drain hole 2 is smaller; a flow rate sensor 3 is arranged in the drain hole 2, and the flow rate sensor 3 is hung at the center of the upper end surface of the drain hole 2; the flow rate sensor 3 is for monitoring the flow rate of water passing through the drain hole 2; the upper end of the water baffle 1 is provided with a handle 4 which is convenient to carry, and the handle 4 is arranged to facilitate carrying and loading and unloading of the water baffle 1; the outer contour of the water baffle plates 1 is matched with the inner contour of the blow-down pipe 5, two water baffle plates 1 are in a group, the two water baffle plates 1 are mutually spaced in parallel and fixedly connected through connecting rods 6, the connecting rods 6 are of cylindrical structures, and the structure and the length of each connecting rod 6 are the same; in actual use, the two water baffles 1 which are connected are put into the drain pipe 5, so that water flow can be effectively blocked, and the water flow can flow through the drain holes 2; the two water baffles 1 can effectively avoid the turbulence generated after the water flows pass through the water drain holes 2, and influence the measurement result; the water baffle 1, the flow velocity sensor 3, the blow-down pipe 5 and the connecting rod 6 are all made of corrosion-resistant materials, and the service life of the device can be effectively prolonged and the use cost can be reduced by adopting the corrosion-resistant materials.
The working process of the utility model is as follows: firstly, bringing two water baffles 1 and a connecting rod 6 to a water flow measuring position, connecting the two water baffles 1 together by the connecting rod 6, putting the whole device into a sewage drain pipe 5 after connecting, pressing the device by hands or heavy objects to enable the outer contour of the water baffles 1 to be closely attached to the inner wall of the sewage drain pipe 5, and taking care that a flow velocity sensor 3 is arranged in a drain hole 2 of the water baffle 1 at the front end of water flow; when the water level of the water flow exceeds the height of the water outlet 2 and the water flow between the two water baffles 1 is stable, recording the value displayed by the flow rate sensor 3, and multiplying the obtained value by the cross-sectional area of the water outlet 2 to obtain the flow value of the water flow; after the measurement is finished, the device is pulled out from the sewage drain pipe 5 by using the handle 4, and the measurement is finished.
The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
