Abstract

The baffle wall style of bottom hollow out is the baffle wall style ontology of right-angled trapezium shape including cross section, and the baffle wall style body bottom portion is uniformly provided with several water stream channels, and several water stream channels are parallel and set, and water stream channel is laid along the right angle waist of right-angled trapezium to oblique waist direction.Water stream channel is arranged in baffle wall style body bottom portion in the utility model, makes baffle wall style body part hollow out, the baffle wall style of bottom hollow out can be such that water flow passes through from hollow-out part when water level is lower, thus influence of the lower degree bottom sill to flow of inlet water and Inlet flow pattern.

Description

The baffle wall style of bottom hollow out
Technical field
The utility model relates to a kind of waterwork structures, are a kind of baffle wall styles of novel bottom hollow out, for energy dissipating and The hydraulic structure of rectification.
Background technique
Existing baffle wall style is mostly made of armored concrete, is met direction of flow and is arranged by upright right-angled trapezium mode, structure Make mostly monoblock type solid construction.Water flow from torrent after baffle wall style by that will be become flowing slowly.Existing baffle wall style is in water flow energy dissipating Aspect has preferable efficiency, but for pumping plant and power station etc. to the higher hydraulic structure of Inlet flow pattern stability requirement simultaneously When carrying out forebay energy-dissipating and rectifying flow, flow velocity is easy to produce unevenly and the case where bias current, is managed to influence the whole of unit And the stability of its operation.
Therefore, it still needs to that certain rectification facilities are arranged in forebay.In view of the convenience constructed, managed, Yi Jiqian The integrally-built stability of bottom of pond plate, rectification and two kinds of functions of energy dissipating, which are combined, just certain necessity.Together When, when water level is lower, existing baffle wall style will lead to that the flow into intake pool is relatively low, and Inlet flow pattern is deteriorated, and influence unit It works normally.
Utility model content
Different location fluidised form difference cannot be efficiently solved in order to solve existing baffle wall style in current hydraulic structure The problem of, more preferably adjustment Inlet flow pattern, the utility model provide a kind of baffle wall style of bottom hollow out, which can be to next While flowing abundant energy dissipating, make, elimination bias current influence more uniform into water velocity flow profile.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
The baffle wall style of bottom hollow out, characterized in that be the baffle wall style ontology of right-angled trapezium shape, the power of disappearing including cross section Bank body bottom portion is uniformly provided with several water stream channels, and several water stream channels are parallel and set, and water stream channel is along the right angle of right-angled trapezium Waist is laid to oblique waist direction.
Further, the cross section outer profile of the water stream channel is vertically connected by two vertical edges, a horizontal edge, and formation is fallen U-shaped structure.
Further, the height of the water stream channel is the half of baffle wall style body height.
Further, the bottom of the water stream channel is flushed with baffle wall style body bottom portion.
Water stream channel is arranged in baffle wall style body bottom portion in the utility model, makes baffle wall style body part hollow out, bottom hollow out Baffle wall style when water level is lower, water flow can be made to pass through from hollow-out part, thus lower degree bottom sill to flow of inlet water and into The influence of water flow state.The utility model is mainly set to the waterwork more demanding to Inlet flow pattern such as pumping plant, power station In forebay.According to the specific fluidised form in river and flow condition requirement, baffle wall style is calculated according to the weir formula of practical weir Height and bank top length.Meanwhile in practice of construction, according to the position that bad fluidised form occurs, fair amount is arranged and along the power that disappears Bank middle line is arranged symmetrically.
The beneficial effects of the utility model are:
The structure carries out energy dissipating to the water flow for entering forebay by setting bank.Meanwhile the water and process flowed out from hollow-out part The water of baffle wall style energy dissipating contacts after bank.Since the flow velocity of two bursts of water flows is different, liquid surface generates biggish frictional force, plays The effect of energy dissipating.Meanwhile kinetic energy is passed to the low speed water by baffle wall style energy dissipating by bottom water flow, this process is in transverse direction It is simultaneous with longitudinal direction, therefore the baffle wall style of bottom hollow out can make the flow velocity of water flow more uniform, eliminate the influence of bias current.? When low water level, water flow can be flowed out from the position of baffle wall style bottom hollow out enters forebay, can guarantee unit in certain situation Continue to operate normally.

Fig. 2 is the front view of the utility model;
Fig. 3 is the top view of the utility model;
Fig. 4 is the left view of the utility model;
In figure: 1 baffle wall style ontology, 2 water stream channels.
Specific embodiment
In Practical Project, according to the requirement of water inlet flow velocity, the position of baffle wall style and the height of baffle wall style are determined.Afterwards According to the actual situation, the position of reasonable arrangement cut-out openings and quantity.This baffle wall style and forebay bottom plate armored concrete One-piece casting.
(rough schematic that above-mentioned attached drawing is a segment length baffle wall style) as shown in Figs 1-4, the baffle wall style of bottom hollow out, It is the baffle wall style ontology 1 of right-angled trapezium shape including cross section, baffle wall style body bottom portion is uniformly provided with several water stream channels 2, is formed Bottom engraved structure, several water stream channels are parallel and set, and water stream channel is laid along the right angle waist of right-angled trapezium to oblique waist direction.
The cross section outer profile of water stream channel is vertically connected by two vertical edges, a horizontal edge, forms inverted U-shaped, water flow The height in channel is the half of baffle wall style body height, and the bottom of water stream channel is flushed with baffle wall style body bottom portion.
The utility model structure is simple, and it is convenient that material therefor obtains, and is improving forebay fluidised form, stablizes water inlet flow velocity side There is preferable effect in face, therefore is the good selection for adjusting forebay fluidised form.
