Abstract

The utility model discloses a river model improves and adds rough body, include and add rough body main part, add rough body main part including a column inner core the arcuation side of column inner core evenly is provided with fillet finned plate, fillet finned plate quantity is among both one kind of 6 or 8, finned plate's column inner core will bulge in inserting the concrete, make it directly be connected with the concrete, be applicable to the connection that adds the same material model of rough body NOT AND, utilize fillet finned plate can make rivers turn to according to the streamline, also utilize finned plate to have certain resistance to rivers and can survey out the roughness, the model tidal level, the velocity of flow is with natural unanimous basically, the playback of better ground of model natural river course rivers motion laws, the symmetry is unanimous around adding the rough body, can be under the same benchmark condition, the problem of rise ebb or reposition of redundant personnel or when converging model test add rough is solved.

Description

A kind of river model improves and adds rough body

Technical field

The utility model relates to river model test technical field, is specifically related to the improvement of a kind of river model and adds rough body.

Background technology

Adding rough is one of key technology of river model test, and it is similar that most river model all needs to add the rough resistance that could meet river model, and the fine or not direct relation that therefore model adds rough effect effect and the precision of river model simulation.

What river model often adopted adds rough body cobble, rubble, concrete cube, flat board and four-bladed vane etc., from macroscopic perspective, it adapts to flume test, play and certain add rough effect, the right discussion for microcosmic mechanism and research are comparatively short of, adding streaming of rough body is that it forms the most important microprocess of macroscopical resistance, research adds rough body and streams and add rough microcosmic mechanism for cognitive model and have very important meaning, there is some problem following in the rough body that adds now used at present, it is existing that to add rough volume morphing irregular, research rugosity numerical value cannot accurately be located, when analyzing roughness in theory, need to arrange transfer and advance matching roughness design formulas according to the difference added between rough body, existingly add rough body and be difficult to well location, add rough shape on the one hand irregular, on the other hand, existingly add rough body material and be also difficult to profit and fasten with glue fixing, and glue is difficult to accept current impacts for a long time, existing triangle or blossom type add rough body due to it adds rough body profile cannot full symmetric, for rising, ebb test cannot accomplish two-way exact test, test compliance is too dull, existing add rough body border be right angle change, there is no fairshaped circular arc chamfering, easily make the actual interference of back-to-back test current.

Utility model content

(1) technical problem that will solve

In order to overcome prior art deficiency, now proposing a kind of river model going for theoretical calculation roughness and improving and add rough body, what it can solve that common unidirectional or two-way river model uses adds rough problem.

(2) technical scheme

Of the present utility modelly to be achieved through the following technical solutions: the utility model proposes a kind of river model and improve and add rough body, comprise and add rough phosphor bodies, describedly add rough phosphor bodies and include a columnar core, be evenly provided with fillet wing plate in the arcuation side of described columnar core.

Improve as one, described fillet wing plate vertically arrange and the height of columnar core higher than the height of fillet wing plate.

As further improvement, described fillet wing plate quantity is 6 pieces or the 8 pieces one in both.

As further improvement, described columnar core and fillet wing plate is one-body molded madely forms.

(3) beneficial effect

The utility model, relative to prior art, has following beneficial effect:

A kind of river model that the utility model proposes improves and adds rough body, the columnar core protruding from wing plate is inserted in concrete, it is made directly to be connected with concrete, be applicable to the connection adding rough body and non-equal material model, utilize wing plate to have certain resistance to current and can determine roughness, model tidal level, flow velocity and natural basically identical, model playback preferably natural river course water movement rule, add before and after rough body symmetrical consistent, can under same base case, solve rise ebb or shunting or conflux time model testing add rough problem.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

1-columnar core; 2-fillet wing plate.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

A kind of river model as shown in Figure 1 improves and adds rough body, comprises and adds rough phosphor bodies, described in add rough phosphor bodies and include a columnar core 1, be evenly provided with fillet wing plate 2 in the side of described columnar core 1.

Wherein, described fillet wing plate 2 vertically arrange and the height of columnar core 1 higher than the height of fillet wing plate 2; Described fillet wing plate 2 quantity is 6 pieces or the 8 pieces one in both; Described columnar core 1 and fillet wing plate 2 are one-body molded madely to be formed.

A kind of river model that above specific embodiment is mentioned improves and adds rough body, it is when specifically using, the columnar core protruding from wing plate is inserted in concrete, it is made directly to be connected with concrete, be applicable to the connection adding rough body and non-equal material model, utilize fillet wing plate that current can be made to turn to by streamline, add rough body and add between rough body and set certain transfer and advance, its roughness has a larger adjusting range, and along with adding the increase hydraulic resistance reduction of rough spacing, the amplitude reduced is more and more less, finally substantially constant; Reynolds number, in about 3500 current intake resistance square districts, behind intake resistance square district, along with the increase hydraulic resistance of degree of flooding relatively reduces, finally reaches certain value.

Select arbitrary fillet wing plate 2 direction consistent with water (flow) direction, symmetrical owing to adding before and after rough body, thus process braided stream conflux add the rough and model testing at ebb tide of rising add rough problem, this adds rough body and has good uniformity, can determine very accurately and stable add roughness, be convenient to experimental study.

Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
