Abstract
A drainage gate capable of automatically selecting a drainage layer for culturing in a pond (weir). The method is realized by adding a water diversion conduit which takes a joint as an axis and can pitch within a certain angle on one side in a pond of a common gate. The water level of the drained water body is determined by pitching the conduit, and when the conduit is crossed in winter and spring, the phenomenon of water temperature and dissolved oxygen double stratification exists seriously, so that the bottom water body becomes a poor water body which has low temperature, low dissolved oxygen, high harmful substance accumulation and difficult discharge, thereby bringing about heavy losses of more than one year to the breeding industry (especially the sea cucumber breeding industry), and the existing gate has very slow improvement effect on the phenomenon and almost no capability; the gate can be used for rapidly and effectively updating poor water bodies, can rapidly and effectively create a good living environment for cultivated species, and prevents and reduces epidemic diseases.
Description
Technical field
The present invention relates to and enclose the emptying gate that usefulness is cultured on the pool (weir).Specifically, relate to a kind of emptying gate that can independently select the draining water layer, utilize this gate to reach and effectively improve water quality fast, prevent or reduce the purpose of eqpidemic disease generation.
Background technology
No matter be freshwater aquiculture or sea-farming, also culture on the pool or culture in the cofferdam no matter enclose, and an emptying gate all must be arranged, with the cooperation of inlet gate under, reach to regulate and improve water quality, be to culture the purpose that species are created good living environment.The existing pool, the emptying gate on weir, on the one hand because structural restriction, make a certain water layer (normally water layer) at the middle and upper levels of the only fixing corresponding pool inner water body of outfall, and in fact when intersect the Winter-Spring, the two stratifications of water-temperature oxygen will especially seriously exist, promptly use big again quantity of exchanged water this moment, still can not improve water quality effectively, especially be difficult to improve quickly and effectively the water quality of bottom water body, the bottom water body has been become be difficult to upgrade " stagnant water " of exchange, become temperature low, dissolved oxygen is low, the bad water body that nuisance is accumulated high " two low height " (and this moment, the end species physique of dwelling was the most fragile exactly, the easiest catching an illness, when water quality is demanded urgently improving), cause the breed species, especially the species of benthonic type eqpidemic disease in this season seriously takes place, and leads to heavy devastating loss.Just to have risen the ground holothruian cultures in recent years is example, and when only intersected the 03-04 Winter-Spring, the loss of Shandong Province one province just reached 800,000,000 yuan.When intersected the 04-05 Winter-Spring, this eqpidemic disease acutely spread in coastal provinces again, loses more huge.The generation of this situation has a variety of causes certainly, but can not improve the water quality of bottom water body quickly and effectively, then is undoubtedly wherein most important reason.
Existing gate, except that above-mentioned can not be improved the defective of water quality effectively, can't be to the greasy dirt slag foam on top layer rapidly in advance to get rid of, can not (guard when needing man-hour with the water level that gate is set in the pool, waste of manpower), can not need to regulate in the season of water temperature special, water temperature is regulated to a certain extent.
Summary of the invention
Purpose of the present invention just provides a kind of draining water layer of independently selecting, and can discharge the top layer dirt rapidly, can independently set water level in the pool, can regulate the emptying gate of water temperature to a certain extent.
For reaching above-mentioned purpose, what the present invention proposed is that a side increase is equipped with and can be regulated the emptying gate of the diversion conduit of pitching by the people in certain angle in the pool of emptying gate.One end of this diversion conduit is connected in gutter or rhone, and is axle with this junction, and the other end (being water inlet) then can artificially be regulated pitching.When nutation arrives extreme lower position, should be able to touch pool inner bottom part; When facing upward the extreme higher position, should be able to reach the top layer of water; Certainly also can after artificial adjusting, be locked in a certain angle.For reaching the above-mentioned purpose that can determine the draining water layer selectively, this water inlet must be one, the water inlet of the flat on a horizontal plane, again in preventing to drain during lower aqueous layer, the excessive water surface vortex that causes of water inlet local pressure difference, the total sectional area of this water inlet, be as far as possible greater than the total sectional area of gutter.When overlooking for the front portion of satisfying this diversion conduit of above-mentioned requirements its profile approximate one fan-shaped; When the water inlet is seen, be a flat rectangle; When seeing from the side, an anterior approximate taper of not having point, and also the upper edge outline of water inlet is longer than the lower edge.As for the several different methods that is connected with of this diversion conduit and gutter or rhone, need not give unnecessary details.
If single diversion conduit weight is excessive, be difficult for regulating in the practicality, this diversion conduit can be divided into two or more conduits and be in parallel, regulate with convenient.
The making of this diversion conduit, available iron material or plastic, or other inexpensive durable materials.
The emptying gate that the present invention proposes not only is suitable for holothruian cultures, also is suitable for other kinds and cultures; Not only be suitable for sea-farming, equally also be suitable for freshwater aquiculture.
When intersect the Winter-Spring, when phenomenon is serious transfer in bottom position water inlet (at this moment if can guarantee that this water inlet is the lowest part of whole water body in the pool on engineering at " one end of two-supremes ", then effect is better), then the bottom water body will fast and effeciently be changed.
When need are discharged top layer greasy dirt slag foam, water inlet to be transferred in surface layer of water, the top layer dirt will be discharged fast.
Good substantially when whole water quality, when only needing to set in the pool water level, water inlet can be locked in a certain angle, the standard-sized sheet inlet gate is realized the flowing water breed.Emptying gate then need not the people go the guard, saves manpower.
Intersect and Winter-Spring when intersecting when the autumn in summer, the water body top layer and the bottom temperature difference are bigger, utilize this gate can regulate and control bottom water temperature to a certain extent.When Xia Qiu intersected, surface temperature was higher, laid particular emphasis on the renewal surface water, delayed and alleviate the harm of high temperature; It is then opposite when intersect the Winter-Spring.
When emptying gate use be the culvert pipe that secretly buries the time, this diversion conduit directly is installed in a side in the pool of culvert pipe.Still decide switching, and select the layer position of the water body of discharging by the diversion conduit with former gate.
And at present comparatively common widely used be the emptying gate of the U-shaped water tank type that opens wide, the somewhere opening links to each other with the diversion conduit in the middle of then must installing one in the inboard of former flashboard again additional this moment, be fixed in the sheet material on the cell wall, formed a surge chamber between this sheet material and the former flashboard.Similarly, select the layer position of institute's water discharging body by the diversion conduit by the switching of former flashboard regulating gate.
The breeding water water yield is huge especially have been determined to utilize natural force to arrange to change water; Utilize natural force to arrange to change in the pool that water determined most of small reservoirs again far below outside the pool; In the pool far below outside the pool, the difficult problem that must cause the bottom water body to be difficult to exchange just, this almost is " fast knot " that is difficult to untie during existing small reservoir is cultured, proposition of the present invention is expected to thoroughly open this " fast knot ", has great practical value.Holothruian cultures industry in the ascendant in recent years is far more than in year 1 year to suffer crushing blow, though find out that bacterial infection is one of reason 05 year mid-term, prerequisite, first-elected most important reason or ecological deterioration.Proposition of the present invention and application can improve the subenvironment of sea cucumber existence effectively, are expected to save the holothruian cultures industry that suffers from heavy losses in succession.
