The utility model content
The utility model technical issues that need to address, it is the purpose of this utility model, be in order to provide a kind of energy sub-category interception drift, and reservoir is efficiently breeded fish, the omnidistance flood control in reservoir downstream, the comprehensive slight drag arrester of anti-pollution three reservoirs that are integrated.
The purpose of this utility model can reach by taking following measure: the comprehensive slight drag arrester of reservoir, its design feature is: comprise the all-round arrester of automatic arrester of drift and slight drag, the automatic arrester of drift preceding, the all-round arrester of slight drag after;
1) the automatic arrester of drift is horizontally installed on the water surface, by some soft straight line or the shaped forms of connecting into of relocatable cross bar, at two ends and each soft tie point place is provided with movable reference column, make the cross bar can be along reference column with the water fluctuation, reference column can running fix in water, make the automatic arrester of drift form linear or shaped form;
2) slight drag be that many facades are formed crooked obstruction structures from the energy arrester, constitute by metal barrier structure, metal barrier structure can comprise vertical tiltedly barrier structure or vertically tiltedly barrier structure and horizontal barrier structure composition mix the barrier structure, fixedly connected with the bank of the water inlet of reservoir, pond on a hill in the two ends of metal barrier structure.
Technical problem of the present utility model also can solve by taking following measure:
Optimum structure of the present utility model be described metal barrier structure by vertically tiltedly barrier structure and horizontal barrier structure form mix the barrier structure, vertically tiltedly the barrier structure is formed by connecting by many vertical flat bonding jumpers and transverse metal bar, and laterally the barrier structure is formed by connecting by many transverse metal bars and longitudinal metal bar; Vertically tiltedly the barrier structure preceding, horizontal barrier structure after, vertically tiltedly the two ends of the bonding jumper of barrier structure are connected, form tilted shape with the transverse metal bar of transverse metal bar and horizontal barrier structure, and laterally fixedly connected with the bank of reservoir, pond on a hill in the edge of barrier structure.
Constitute vertically tiltedly 1.5～3 times of the interval that is spaced apart the transverse metal bar that constitutes horizontal barrier structure of the flat bonding jumper of barrier structure.

Design principle of the present utility model is as follows:
Levy according to floating condition of drift in the water and drift; The bank half interval contour is longer than straight line; The most height of its bodily form of the fish that reservoir is put in a suitable place to breed comprehensively develop greater than width etc.
Drift in the water as stated in the Background Art when the transversary that runs into tight stream district stops, when the thrust of water then sinks under the water greater than its buoyancy, slips over obstruction, floats and escapes; Then submissively stop less than its buoyancy when the thrust of water, the latter is squeezing the former, and is neither leading, and also not heavy escaping is with the water lifting.When the setting structure of running into the area of slack water stops, then escape in the time of escaping to about montant, can not escape and submissively stop after being obstructed, the latter neither also is not shifted up and down in advance by the former, with the water landing.When running into the setting structure obstruction in tight stream district, then escape fast in the time of escaping to about montant, be crushed on after being obstructed on the montant or the thing that is obstructed, the latter is in turn pressing the former.Flood continue to raise, and the buoyancy of drift then continues to float during greater than the pressure of water; When buoyancy then floods in the water during less than the pressure of water gradually, how high flood rise is, and how dark drift then flood, and the latter in turn carries out (the all-round arrester of little cloudy power is not built in this zone as far as possible, or landform is transformed).When meeting the structure that leans forward (being oblique grid) and stopping, erect the total movement feature that structure stops, also be subjected to water and promote drift and act on upwards decomposing force on the oblique grid, strengthen its come-up dynamics, reduce obstruction water except that keeping.When drift rests on certain waters and meets wind, can make it crowded forward or drift about forward.Drift about to make it speed up with the wind, drifts about against the wind to make its speed slow down or flow backwards.Crosswind drifts about its direction is aweather tiltedly floated.

3, reservoir is kept afloat and be located at drift in the water science of carrying out entirely and handle, make and float forage all to stay in fish culture in reservoir, significantly reduce cost; Make the unlikely downstream that flows to of the wood, the bamboo that grow up stop up river course facilities such as bridge Beam, guarantee that they reach the security of the lives and property of two banks along the river; Domestic refuse and other drift are unlikely flow to the downstream polluted source, make the river course sanitation and hygiene.When falling flood, drift retreats automatically away from blocking the fish structure, so that work.
Description of drawings
Fig. 1 is the structure vertical view of the utility model embodiment 1.
Fig. 2 is the front view of the utility model embodiment 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
From Fig. 1, Fig. 2 as can be known, embodiment 1 of the present utility model comprises automatic arrester 1 of drift and the all-round arrester 2 of slight drag; The automatic arrester 1 of drift is horizontally installed on the water surface, by some relocatable cross bar 3 soft straight line or shaped forms of connecting into, at two ends and each soft tie point place is provided with movable reference column 4, make the cross bar 3 can be along reference column 4 with the water fluctuation, reference column 4 can running fix in water, make the automatic arrester 2 of drift form linear or shaped forms; Slight drag be that many facades are formed crooked obstruction structures from energy arrester 2, constitute by metal barrier structure 5, metal barrier structure 5 is mixed the barrier structure by what vertical tiltedly barrier structure 6 and horizontal barrier structure 7 were formed, vertically tiltedly barrier structure 6 is formed by connecting by many vertical flat bonding jumpers 8 and transverse metal bar 9, and laterally barrier structure 7 is formed by connecting by many transverse metal bars 10 and longitudinal metal bar 11; Fixedly connected with the bank of the water inlet of reservoir, pond on a hill in the two ends of metal barrier structure 5.
In the present embodiment:
The soft Len req (most economical) that connects into of the automatic arrester 1 usefulness bamboo of drift, horizontally set, when the river surface span was big, the centre should be provided with some limited posts to disperse pulling force; When arc was provided with, some limited posts should be established with setting in the centre.The backstay established of its two ends landform vertical stratification is done triangularity to two ends of arrester and is placed on the bar, makes it with the water landing; Ramp structure can set up fixed point to fix in the appropriate location on the slope, it is floated downward to arrive low water level, come-up can arrive the highest excessive flood height, water surface drift is all stopped outside preceding 4 meters of device all can the moon be blocked in slight drag (two ends should more greatly), so that each device is handled.Concentrate on fish culture in reservoir to floating the forage that takes, float the wood, bamboo, domestic refuse and other drift that come and recycle, avoid flowing to the downstream to the river course facility, two banks cause disaster along the river, and the water source is polluted, and the bank health is caused damage.
Slight drag all can arrester 2 be made up of vertically oblique barrier structure 6 and horizontal barrier structure 7 metal barrier structure 5, is that a kind of many facades are formed crooked obstruction structures.Because the two sides half interval contour is longer than straight line, so warp architecture can increase its clean discharge area, reduces flow velocity, reduces resistance, and total stretches into broad waters simultaneously, and water velocity further reduces, and formed resistance is littler.
Vertically tiltedly barrier structure 6 constitutes oblique grid, adopts the band iron setting to gain in strength, and reduces resistance.It is about two times of fish corral at interval, makes its existing enough intensity, can reduce resistance again, respectively establishes the movable grizzly bar of 1～2 sash fastener formula of shaking the head at its two end, so that open the fence gate work that enters at any time.
Tiltedly the grid main task is to hold back the drift of each level of submerged, and cooperates with fish corral under the promotion of water and make its come-up, with the resistance of minimizing to water; It and fish corral maintain a certain distance, and the drift of holding back does not touch fish corral, make it indeformable, the unlikely escape of the fish of putting in a suitable place to breed; After disconnecting, the automatic arrester contingency of water surface drift can further replace its work; When flood descended, drift was tiltedly retreating away from fish corral under the grid effect with falling under water, so that work.
Laterally barrier structure 7 constitutes the fish corral of culture in enclosure fishes, adopts the band iron setting, to gain in strength, reduces resistance, and the bodily form great majority of fish are flat, and its height is greater than width, and is that have even big several times.Breed fish fry highly according to plan, the horizontally set grizzly bar not only effectively stops the fish escape, increases it simultaneously at interval, reduces construction cost, and the clearance dynamics of drift is reduced to bottom line to resistance during increasing.
When extraodinary flood surpasses oblique grid, the automatic arrester of water surface drift is just in case disconnect, and fish corral will further replace automatic arrester 1 of water surface drift and the tiltedly work of grid.
Between flood period, under the least favorable condition that the automatic arrester contingency of water surface drift disconnects, the working condition of the all-round arrester of slight drag:
The automatic arrester of water surface drift is just in case after disconnecting, drift is gathered around to oblique grid, and its grizzly bar is not very big at interval, to directly float less than being shorter than of, lateral drift, its projection of tiltedly floating is shorter than its all letting pass at interval, big therebetween every all be trapped.By the stifled passage of having expired in cross section, follow-up is littler short more all impassable earlier, and the length overwhelming majority of drift surpasses it at interval, and therefore the quantity of letting pass is very limited.Flood begins a very long time, and to float the drift that comes all be little, and tiltedly the grid drift that begins to hold back must be little, and diameter has only several centimetres, only have an appointment half of diameter of the part that sinks under the water, resistance to water is very limited, and big drift is arranged between the back, but very little from the influence far away of oblique grid.
After tiltedly the grid drift of letting pass ran into fish corral, because the interval of fish corral is less, the space was long, therefore all can both let pass in (only a few band branch except) less than its drift at interval, greatly therebetween every be trapped all.Because tiltedly grid are let pass all is that flood floats the little drift that comes when beginning, so the quantity that fish corral is held back seldom, and the resistance of formation is very limited.
Use graphic method below, the stressing conditions of the all-round arrester of slight drag be described:
As shown in Figure 1 and Figure 2, from front end (being the top), to preceding organ timbering, be at interval, scratch line to oral area and be each Resistance Level:
The suffered resistance of first Resistance Level is the fish corral in the entire front end facade, the drift of corresponding tiltedly grid and interception thereof (contain keep afloat and total flooding water in) and this district in obstructions generations such as post, Beam.This this obstruction accounts for mouthful wide half in the projection of oral area, their residing waters broadnesses, water velocity is low, though water is had certain obstruction, constituting certain water level trend that falling thereafter, but under it and about to cross area very big, water replenishes up so that the principle of linker is very fast, the front and back drop is very little, and the resistance that causes is very little.
After omit than the first area in the zone at the second Resistance Level place, water flow velocity slightly increases, but about the obstruction on two limits just much little in the ratio of the shared oral area of projection of oral area, though it produces certain obstruction to water, its back also produces certain height of water trend, but the middle part and about the discharge area, below very big, water replenishes up soon, formed drop is very little, and is littler to the resistance of water.
Obstruction is at the resistance that each Resistance Level produces, and the portion of shutting up from the top is calculated, and gradually by little extremely little, has not just had obstruction to oral area is basic, and current are unimpeded, whole device highly effective and safe.
In sum: the all-round arrester of comprehensive slight drag is that the various drift people in the water are dispersed in the level of three different in flow rate: the water surface drift of enormous amount, stopped in water surface broadness, zone that flow velocity is low by the automatic arrester of water surface drift; Drift in the few heavy water of quantity is blocked in the higher zone of flow velocity by oblique grid resistance; The drift that oblique grid clearance is held back by fish corral is insignificant.Fish corral is a warp architecture simultaneously, and its area surpasses old-fashioned two times, and stretches into broad waters, water velocity is low, grizzly bar is at interval big than old-fashioned, and it is stopped up by drift hardly, and the resistance of its unit area was less than old-fashioned two minutes one (be about three fens about one).Structure stress is better, safe and reliable to operation than old-fashioned.When flood descended, tiltedly the drift behind the grid was all automatically away from fish corral, so that work.
Points for attention in the all-round arrester design of comprehensive slight drag
Addressing: the all-round arrester of comprehensive slight drag should be built on the lower position of water surface broad, water velocity, still is parked on original level with the water fluctuation, with the resistance of minimizing to water after making the resistance of drift objective reality.
Slight drag all can arrester the end to the height cross section at the end (promptly falling the spillway top of Hong Yihong device) of spillway should be greater than excessive big vast cross section, so that during extraodinary flood, slight drag all can arrester clean discharge area be about four times of the especially big excessive big vast cross section of spillway (the clean discharge area of the curved allusion quotation structure of the all-round arrester of slight drag, more than at the bottom of the spillway and below respectively be about two times of especially big excessive big vast cross section).
The all-round arrester of slight drag is to the distance of spillway, should be greater than 1.5 times of the all-round arrester height of slight drag, make just in case after slight drag all can arrester meets accident, flood was smooth and easy as usual.
The points for attention of the automatic arrester of water surface drift: each limited post will have enough intensity, and its height is a little more than the extraodinary flood height, in case the arrival of super extraodinary flood.
The points for attention of the all-round arrester of slight drag:
1, the height of horizontal Beam is fixed with practicality: the top of the Beam on the ground Beam face should be than lower slightly at the bottom of the spillway or fair, and the end of the 2nd Beam should surpass especially big excessive flood height, in order to flood passage; Beam top in the ends to the of the 2nd Beam three is not less than 1.5 meters, in case the diving of extraodinary flood macrura reevesii is escaped.And imbed 1 of 0.5 meter high iron every 2 meters on the 3rd Beam top, and be used for fixing wood (bamboo) bar, when meeting super extraodinary flood, hang up anti-jump net and stop the fish escape.
2, fish corral grizzly bar setting at interval:
1, the minimum constructive height kind that breeds fish fry with plan is decided: the interval of making like this is less relatively, and is less by the ability of drift, and bigger to the resistance of water, construction cost is higher.
2, the second from the bottom kind of low height kind that breeds fish fry with plan decided: the interval of making like this is bigger, and the drift that passes through is also relatively large, and less to the resistance of water, construction cost is lower.But fry should be put in a suitable place to breed in rainy season earlier month or rainy season, and set up defences at the fish corral side arm and to escape net and prevent fish flight.When rainy season the macrura reevesii of arriving grow up, can't from fish corral, escape, remove this moment and anti-ly escape net, meet flood to arrive.
Also the fry that plan can be put in a suitable place to breed the minimum constructive height kind is bought greatly, and it can not be escaped from fish corral, and cost of investment is heavier like this, but fish looks soon, has under the situation of capital, and this method is the most favourable.
3, tiltedly Beam, the post of the connection of the grizzly bar of grid and spring will have enough intensity and buried depth.The grizzly bar of oblique grid is bearing the thrust of water and the point of the irregular big drift (diameter can reach tens centimetres) of submerged contacts high thrust, the automatic arrester of water surface drift is just in case after disconnecting in the time of also will bearing extraodinary flood, all water surface drift is gathered around to the thrust of being born, and acts on and the thrust of oblique grid projection with wide drift with the equidirectional high wind of flood.Therefore, grizzly bar will have enough intensity to contend with it.
Tiltedly the grizzly bar upper fixed of grid is on horizontal Beam and post, and the below is fixed on the ground Beam; The grizzly bar of fish corral is fixed on the post.Therefore, these Beam, post will have enough intensity and buried depth to be contended with.Particularly tiltedly the last Beam of grid and ground Beam are stressed bigger.
