In a kind of aquatic fry growing pond for the new equipment of draining
Technical field
The utility model relates to the new equipment for draining in a kind of aquatic fry growing pond, belongs to aquatic fry growing technical field.
Background technology
In aquatic fry growing is produced, the residual bait ight soil of water body and other metabolite can affect water quality, cause water body organism, ammonia nitrogen, the too high situation of nitrite equal size, and cultivated animals is worked the mischief, changing water and can effectively improve water quality, is conventional technological means in producing.Change water operation and be divided into draining and the two parts that add water, add water that it is very easy to operate, but drain operation takes time and effort, and be easily subject to the restriction of pool outer water position difference of height in pond.
Now widely used drainage arrangement mainly contains two kinds: draining bucket and draining net cage are all to carry out draining by the principle of siphon.First by the draining bucket that is connected with flexible pipe water inlet, (draining bucket is covered with the bolting silk net of suitable order number, its introduction refers to claims and Figure of description) put into water, flexible pipe remainder is also put into water, only stay hose water end (W.E.) adjoined water surface top, object is the air as far as possible draining in draining bucket and flexible pipe, block hose water end (W.E.), flexible pipe is hauled out to the water surface, and (hose length is wanted long enough, draining bucket must be below the water surface), be placed on the lower place of physical features outside pond, make the outlet of hose water end (W.E.) in the place lower than pool inner water face, decontrol outlet, utilize atmospheric pressure that water is discharged.This method has several shortcomings: (1) operation is wasted time and energy, and operates and be difficult for from nursery pond along time away from when the water surface; (2) in the time that water body organic particulate matter is more, easily stop up draining bucket net and cause draining interrupt; (3) flow velocity of draining is uncontrollable, the too fast damage that tends to cause cultivated animals of flow velocity; (4) scope of application is restricted, in actual seedling culturing vehicle, often much lower than outside corridor at the bottom of nursery pond pond, and water level is lower in the nursery pond like this, and lower than outside pond when ground, this method just can not have been used.
Also having a kind of water discharge method is to replace draining bucket with net cage, net cage is rectangular build, net cage is covered with the bolting silk net of suitable order number outward, net cage 5 bread are wrapped up in bolting silk net, only stay one side open upwards, when use, put into nursery pond, bolting silk net will exceed the nursery pond water surface, flexible pipe is put into net cage, flexible pipe water inlet is placed in to net cage bottom, block hose water end (W.E.) and leave the water fast, be placed on lower outside pond, make water side lower than the nursery pond water surface, decontrol water side and can start draining, this method is identical with first method in essence, but operation is trouble more, because the contact-making surface of net cage and water is larger, so solved the susceptible to plugging problem of draining bucket in first method, but the problem of other several aspects still cannot solve.
Utility model content
In order to overcome troublesome poeration, drainage speed is uncontrollable, drain operation is easily interrupted, the scope of application is less deficiency, the utility model provides a kind of new drainage arrangement.
The utility model scheme is as follows:
In a kind of aquatic fry growing pond for the new equipment of draining, in nursery pond drainpipe bottom, up 10cm~20cm is fixedly connected with threeway, in threeway, be connected with wired hose, on the wired hose other end, be connected with draining bucket, between draining bucket and wired hose, be provided with valve body switch.Draining bucket top is provided with screen pack.Draining bucket is arranged on support casing, and support casing is arranged on support, is provided with set screw on support casing, can be used for regulating the height of support casing, thereby regulates the height of draining bucket.
Said apparatus is in the time of not draining, more than draining bucket is suspended on the water surface, when drain operation, as long as draining bucket is put into water, draining bucket least significant end is fixed on to the water level place that need to be discharged to, utilizes water level difference of height automatically to carry out drain operation, drainage speed can regulate by valve body switch, to requiring after water level, get final product automatic end operation until draining.Draining bucket top is provided with screen pack, is used for preventing that the young is discharged from the time of draining.
The beneficial effect of this utility model is: (1) operation is very easy, when draining, only draining bucket need be put into below the water surface, level altitude maintains an equal level its lower end lowest part and the water level that need to drain into, and can carry out drain operation automatic end operation, simple to operation; (2), because draining bucket, wired hose in drainage procedure are all below the water surface, the situation that does not exist air to enter, enters the situation that draining bucket results in blockage and occurs so be not prone to air; (3) because the devices such as the draining bucket of this method are all fixed on a nursery pond at ordinary times, specially pond is special, so just eliminated the risk of cross-infection between nursery pond; (4) because this method has been installed switch between draining bucket and intubate, so can regulate drainage speed with switch according to production requirement; (5) because the intubate of all nursery ponds is all its lowest position at the bottom of pond, so this method draining does not have the restriction of water-head, the scope of application is very wide.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, to better understand the utility model.
In aquatic fry growing pond as shown in Figure 1 for the new equipment of draining, in nursery pond drainpipe 1 bottom, up 10cm~20cm is fixedly connected with threeway 2, in threeway 2, be connected with wired hose 3, on wired hose 3 other ends, be connected with draining bucket 6, between draining bucket 6 and wired hose 3, be provided with valve body switch 4.Draining bucket 6 tops are provided with screen pack 5.Draining bucket 6 is arranged on support casing 9, and support casing 9 is arranged on support 7, is provided with set screw 8 on support casing 9, can be used for regulating the height of support casing 9, thereby regulates the height of draining bucket 6.
Said apparatus is in the time of not draining, more than draining bucket 6 is suspended on the water surface, when drain operation, as long as draining bucket 6 is put into water, draining bucket 6 least significant ends are fixed on to the water level place that need to be discharged to, utilize water level difference of height automatically to carry out drain operation, drainage speed can regulate by valve body switch 4, to requiring after water level, get final product automatic end operation until draining.Draining bucket 6 tops are provided with screen pack 5, are used for preventing that the young is discharged from the time of draining.
When said apparatus uses, detailed process is: before 1) producing, should connect this device by above-mentioned requirements; 2) after determining the discharge level needing, draining bucket 6 is put into water, draining bucket 6 bottoms and the discharge level needing are maintained an equal level.3) observe draining flow velocity, regulate by valve body switch 4, make it to meet drainage requirement.4) mix up after flow velocity, system Auto-drainage, is discharged to after the water level needing, and drain operation stops automatically.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
