Abstract
The utility model relates to a moving type measuring weir which comprises a pond body formed by the enclosing of a plurality of plate pieces, wherein the middle of the pond body is provided with a longitudinal weir plate which can divide the pond body into an energy dissipation pond and a measuring pond; and the bottom of the energy dissipation pond is provided with a water inlet, the upper part of the weir plate is provided with a plurality of overflow holes, and a V-shaped weir port is formed in the side wall of the measuring pond, which is far from the weir plate. The moving type measuring weir provided by the utility model is used for measuring water flows of different models, is easy to move and assembly, suitable for different occasions and particularly suitable for experimental research.
Description
Technical field
The utility model relates to a kind of mobile model weir, is particularly useful for experimental study, belongs to the measurement instrument technical field.
Background technology
According to the knowledge of the applicant, often to measure or control discharge in the hydraulic engineering, especially when experimental study, need to carry out measuring water flow to a large amount of change models.Although market has flow meter specially, they often are limited by the factors such as structural design, flow range, are difficult to be common to the measuring water flow of various models; And the existing concrete sharp-crested weir can not move, and can only be used for the measurement of fixed position, is not easy to experimental study.
The utility model content
The purpose of this utility model is: the problem for above-mentioned prior art exists, a kind of mobile model weir is proposed, and can be common to the measuring water flow of various models, be easy to mobile and assembling, be applicable to various occasion.
In order to reach above purpose, the technical solution of the utility model is as follows:
A kind of mobile model weir comprises the pond body, it is characterized in that, described pond body is surrounded by some plates, and body middle part in described pond is provided with the vertical weir plate that the pond body is divided into energy dissipation tank and measuring cell; Described energy dissipation tank bottom has water inlet, and described weir plate top has some spillway holes, and described measuring cell has the V-arrangement crest of weir away from the sidewall of weir plate.
The utility model can be common to the measuring water flow of various models, is easy to mobile and assembling, is applicable to various occasion, is particularly useful for experimental study.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Embodiment
Present embodiment mobile model weir basic structure comprises the pond body 1 that is surrounded by some plates as shown in Figure 1, and body 1 middle part in pond is provided with the vertical weir plate 2 that pond body 1 is divided into energy dissipation tank 1-1 and measuring cell 1-2; Energy dissipation tank 1-1 bottom has water inlet 3, and weir plate 2 tops have some spillway holes 4, and measuring cell 1-2 has V-arrangement crest of weir 5 away from the sidewall of weir plate 2.
Plate is plastic plate (preferred polyvinyl chloride panel), good flame resistance, and chemical stability is good, has high strength, high rigidity, high rigidity, good electric insulating quality, easily bonding, easily welding is easily painted, and cheap, corrosion resistance is strong.
Spillway hole 4 is scattered at least two rows.
V-arrangement crest of weir 5 angles are the right angle.
Application case:
Energy dissipation tank 1-1: length L 2=0.8m.
Measuring cell 1-2: length L 1=0.8m, width B=0.9m.
V-arrangement crest of weir 5: top margin length b=0.44m, at the bottom of summit, bottom and the pond apart from a=0.6m.
Distance h=the 0.22m on the water surface and summit, V-arrangement crest of weir 5 bottom.
Calculated flow rate Q=1.4h accordingly
5/2=0.032 cube of meter per second.
In addition, water inlet 3 diameters are 0.2m, and water inlet 3 centers and weir plate 2 distances are 0.2m; Spillway hole 4 diameters are 0.06m, are scattered in three rows, five of every rows, and alignment, descending overflowing water hole 4 and bee-line at the bottom of the pond most is 0.45m.
The present embodiment flowmeter can be common to the measuring water flow of various models, is easy to mobile and assembling, selects as required the plate of appropriate size to get final product, and is applicable to various occasion, is particularly useful for experimental study.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
