Abstract
A kind of waterpower self-control drag-line checkdam, to be horizontally set on riverbed and to adopt single hop or multistage to arrange, single hop checkdam is made up of dash steel plate, Elastic Steel drag-line, pull bar cylinder and hinged-support, dash steel plate is the sandwich be made up of two blocks of cuboid steel plates, vertical reinforcing rib is provided with between two-layered steel plates, dash steel plate is laterally hinged with on riverbed by hinged-support, one end of Elastic Steel drag-line is articulated with on dash steel plate upstream side riverbed by hinged-support, and the other end of Elastic Steel drag-line and the top of dash steel plate are fixed; Pull bar jacket casing is outside Elastic Steel drag-line, and lower end is connected with steel cable riverbed hinged-support.Advantage of the present utility model: this checkdam has the feature of standardized production, reliable in quality, the technology maturation of employing and construction is simple, has higher bearing capacity; In the dash phase, dash steel dam can raise dash automatically according to design water level; In flood period, dash steel dam is reduced to original state automatically, less on river course flood impact, has significant economic and practical.
Description
Technical field
The utility model relates to the checkdam in hydraulic engineering, particularly a kind of waterpower self-control drag-line checkdam.
Background technology
In recent years, the river comprehensive realignment demand for the purpose of water environment and Ecology protection and view and entertainment environment are built increases day by day.For guaranteeing the safety of the people's lies and property, the most of river of China is under design flood condition, flow is large, the depth of water and the water surface is wide, and in non-flood season, then flow is less, and water is shallow and the water surface is narrow, thus defines the discrepancy in elevation of several meters between higher dyke and the lower water surface, have a strong impact on River Landscape sight, be unfavorable for that hydrophilic, the near water of the people is movable.In order under the precondition ensureing flood passage safety, promote the ecological landscaping effect in two sides, river course, for the feature that flooding and drying flux difference in river is larger, research and development possess the emphasis that the ecological hydraulic structure of multi-functional low impact is current development.
Utility model content
The purpose of this utility model is for above-mentioned existing problems, and provide a kind of waterpower self-control drag-line checkdam, this checkdam takes steel dam to bear water retaining function in conjunction with the mode of steel cable, in the dash phase, and steel dam lifting gradually, dash; In flood period, steel dam returns to original state under the pulling force effect of steel cable, reduces the impact on flood passage, and this structural principle is simple, and easy construction, has significant economic and practical.
The technical solution of the utility model:
A kind of waterpower self-control drag-line checkdam, to be horizontally set on riverbed and to adopt single hop or multistage to arrange, single hop checkdam is made up of dash steel plate, Elastic Steel drag-line, pull bar cylinder and hinged-support, dash steel plate is the sandwich be made up of two blocks of cuboid steel plates, vertical reinforcing rib is provided with between two-layered steel plates, dash steel plate is laterally hinged with on riverbed by hinged-support, one end of Elastic Steel drag-line is articulated with on dash steel plate upstream side riverbed by hinged-support, and the other end of Elastic Steel drag-line and the top of dash steel plate are fixed; Pull bar jacket casing is outside Elastic Steel drag-line, and lower end is connected with steel cable riverbed hinged-support.
Operating principle of the present utility model:
Original state, when wet season or experience flood, dash steel plate has a down dip in river bed with the support of minimum angles at pull bar cylinder.Enter dry season, river course upstream flowrate reduces, the level of tail water reduces thereupon, there is water-head in dash steel plate both sides, after water-head is greater than and rises dam critical potential difference, dash steel plate, under the effect of two lateral water pressure differences, overcomes the lifting gradually of steel cable pulling force, harmony height upper pond level, plays the function of checkdam.If again enter the wet season, or when running into flood, increase with the discharge of river raises by the dash steel dam level of tail water, dash steel plate two lateral water pressure difference reduces gradually, after two lateral water pressure differences are decreased to dam critical potential difference of collapsing, dash steel plate is under the effect of steel cable pulling force and two lateral water pressure differences, and automatic falling head returns to original state, to reduce the impact on river course flood.Pull bar cylinder protects steel cable in flood passage process.
The beneficial effects of the utility model are:
This drag-line has the feature of standardized production, reliable in quality from lifting checkdam, the technology maturation of employing and construction is simple, has higher bearing capacity; In the dash phase, dash steel dam can raise dash automatically according to design water level; In flood period, dash steel dam is reduced to original state automatically, less on river course flood impact, has significant economic and practical.

Detailed description of the invention
Embodiment:
A kind of waterpower self-control drag-line checkdam, as Figure 1-5, to be horizontally set on riverbed 5 and to adopt eight sections of settings, single hop checkdam is made up of dash steel plate 1, Elastic Steel drag-line 2, pull bar cylinder 3 and hinged-support 4a, 4b, dash steel plate 1 is the sandwich be made up of two blocks of cuboid steel plates, vertical reinforcing rib is provided with between two-layered steel plates, dash steel plate 1 is laterally hinged with on riverbed 5 by hinged-support 4a, one end of Elastic Steel drag-line 2 is articulated with on dash steel plate upstream side riverbed 5 by hinged-support 4b, and the other end of Elastic Steel drag-line 2 and the top of dash steel plate 1 are fixed; Pull bar cylinder 3 is enclosed within outside Elastic Steel drag-line 2, and lower end is connected with steel cable riverbed hinged-support 4b.
In this embodiment, the wide 5.0m of dash steel plate, high 2.5m, thick 0.3m, dash steel plate initial angle is 17 °; Elastic Steel drag-line coefficient of elasticity 10
4n/m; Pull bar cylinder diameter 0.1m, length 1.2m, initial angle 25 °.
