Abstract
The utility model relates to a pool water discharge technology, in particular to a surface layer fresh water discharge device for a seawater culture pool. The surface layer fresh water discharge device has the technical scheme that the bottom of the pool is provided with a bottom water discharge pipe, the top of the pool is provided with a surface layer water discharge pipe, and in addition, water discharge valves are respectively arranged on the bottom and surface layer water discharge pipes. The surface layer fresh water discharge device for the seawater culture pool has the advantages that the structure is simple, the use is convenient, the cost is low, the surface layer fresh water discharge device for the seawater culture pool is applicable to the surface layer fresh water discharge of most sea water culture pools, the rain can be fast discharged in time, the water quality state stability of the pool is maintained, and the yield and the quality of a cultured product are improved.
Description
Technical field
The utility model relates to a kind of water discharge technology of pond, especially a kind of device that is used for the top layer fresh water discharging of seawater aquaculturing pond.
Background technology
As everyone knows; In sea pond is cultured; Water quality is to influence the key factor that the mariculture object grows; Good water quality and substrate are to influence the key factor that the mariculture object grows, and good water quality and substrate condition can provide the natural bait of high-quality and the living environment that suits for culturing object, have directly determined the success or failure of breeding production.According to statistics, present aquiculture disease more than 85% is to cause because of poor water quality.Pond water quality is carried out scientific management, is the major measure that reduces disease, improves breed object output and quality.Heavy rain is a key factor that causes seawater quality sudden change, and this is because the seawater salinity in the seawater aquaculturing pond generally must remain on more than the 22ppt, with dissolved oxygen content more than 4.5mg/l.Heavy rain is later because the rainwater salinity is lower; With cause pond salinity water and proportion layering after the contact with sea water of high salinity, the upper strata dissolved oxygen can not be transported to bottom through convection current up and down, pond ammonia nitrogen, hydrogen sulphide, nitrite equal extra large content of material can be increased; Very easily cause and culture object large tracts of land anoxia asphyxia and nitrite intoxication; And because water quality mutation, assorted algae is prone to dead sinking in the pond in, furniture the deterioration of water environment.Given this, seawater aquaculturing pond must discharge water water at heavy rain later as early as possible.
Present seawater aquaculturing pond generally all has inlet gate and emptying gate, and emptying gate is to build in and the corresponding pond of inlet gate lowest part, from the water inlet to the discharge outlet, also certain gradient will be arranged at the bottom of the pond, in order to draining Chi Shui.Behind the heavy rain during draining; Take to open the Chi Shuihou that an emptying gate discharging part contains rainwater, closing emptying gate, open the method that inlet gate carries out again Na Shui; In this water discharge method during draining storm-water drainage not thorough; The still rainwater that reintegrates and the mixing water of seawater have so just caused breed pool inner water body salinity low, to culturing the growth deleterious impact of object.Large-area in addition seawater aquaculturing pond only adopts drainage gate to discharge rainwater and also exists the untimely defective of discharging.
Summary of the invention
The purpose of the utility model is the defective to prior art, and the top layer fresh water tapping equipment of the convenient seawater aquaculturing pond quick, with low cost of a kind of simple in structure, draining is provided.
Its technical scheme is: pond bottom is provided with the bottom discharge pipe, and top, pond is provided with the top layer drainpipe, and is equipped with draining valve on bottom and the top layer drainpipe.Its course of work is following: the water in the emptying pond if desired, can only open the valve of bottom discharge pipe; When in rainy season, especially during heavy rain, need to discharge the rainwater in the pond, can only open the valve of top layer drainpipe, the fresh water that will be positioned at the top layer, pond is in time discharged, and keeps the most of seawater salinity in the pond constant; If run into extra torrential rain, especially certainly will need to discharge fresh water fast for large-area seawater aquaculturing pond, the valve that can open bottom discharge pipe and top layer drainpipe simultaneously carries out quick draining.The top layer drainpipe is arranged on the top in pond, and particular location can be set according to the actual needs of pond draining.
In order to simplify circuit design, handled easily, described bottom and top layer drainpipe interconnect, and promptly two drainpipes can a public flowing line, can reduce operating cost, and when drawing water operation if desired, the two just can public a set of equipment.
The utility model is simple in structure, easy to use, with low cost, is applicable to the top layer fresh water discharging of existing most of seawater aquaculturing ponds, and it can discharge rainwater fast immediately, keeps the stable of pond water quality state, improves the quality of the output of institute's cultured product.
Description of drawings
The structural representation of Fig. 1 the utility model;
Among the figure: 1, pond, 2, the bottom discharge pipe, 3, the bottom discharge valve, 4, the top layer drainpipe, 5, the top layer draining valve, 6, total discharge outlet.
Embodiment
Below in conjunction with accompanying drawing and instantiation the utility model is described further, but not as the qualification of the utility model.
With reference to figure 1; A kind of top layer fresh water tapping equipment that is used for seawater aquaculturing pond; Comprise that 1 bottom, pond is provided with bottom discharge pipe 2, top is provided with top layer drainpipe 4, and bottom and top layer drainpipe interconnect, be respectively equipped with bottom discharge valve 3 and top layer draining valve 5 on it.
According to actual needs, can open bottom discharge valve 3 or top layer draining valve 5 separately, promptly can the water in the pond be discharged by total discharge outlet 6 through bottom discharge pipe 2 or top layer drainpipe 4; Especially for rainy season, only the top layer draining valve of open top part can make things convenient for instant discharge rainwater, has both guaranteed the stable of water quality condition in the pond, and number of times and quantity that again can less Na Shui have reduced production cost.
Except that the described technical characterictic of this specification, be the known technology of those skilled in the art.
