Specific embodiment

The technology of the utility model is described in detail in the utility model in order to better understand with specific embodiment below Scheme, but the utility model is not limited thereto.

As shown in Figure 1, the utility model provides a kind of water installations of changing for aquiculture net cage, including drainpipe 1, Pipeline circle 2 and connecting tube 3；The pipeline circle 2 is the round tubular of both ends open；The pipe is inserted into one end of the connecting tube 3 In road circle 2, the other end is located at the outside of the pipeline circle 2, and the axis of the connecting tube 3 and the axis of the pipeline circle 2 mutually hang down Directly；The connecting tube 3 is located at one end outside the pipeline circle 2 equipped with internal screw thread 31 and external screw thread 32；The drainpipe 3 One end is equipped with internal screw thread or external screw thread；The connecting tube 3 is connected through a screw thread with drainpipe 1；The other end of the drainpipe 1 with Hose 9 is connected.

Using the utility model when changing water installations, upper hose 9,9 other end of hose are connected in one end of drainpipe 1 It is put into the lower Sheng waste water container of water level, then water installations will be changed and be put into and start to drain in net cage, drained using siphon principle, it is right The disturbance very little of water body, will not influence fry growth.And the waste water in net cage passes through pipeline circle 2 first and is inhaled into drainpipe 1, It is discharged again by hose 9, the setting of pipeline circle 2 can be further reduced water disturbance, be that the normal growth of fry is created Advantage.Furthermore, it is possible to the internal screw thread 31 of connecting tube 3 is threadedly coupled with externally threaded thinner drainpipe 1, or The external screw thread 32 of connecting tube 3 is threadedly coupled with the thicker drainpipe 1 of internal thread, by the row for connecting different-diameter size Water pipe 1, carrys out regulation and control drain discharge, and use is more flexible, conveniently.It, can also be in the internal screw thread 31 of connecting tube 3 when needing Or the matching connecting tube 3 with internal and external threads is reconnected on external screw thread 32 can by the connection of multiple connecting tubes 3 Pipe diameter size with the drainpipe 1 being more alternatively connected in connecting tube 3 as needed makes to change water installations more practical.When When water level drops to certain altitude, new water is added, so that pond water quality is kept fresh, guarantees the growth needs of fry.

When changing water, after hose 9 is connected to 1 one end of drainpipe, it is possible that hose 9 is from row during changing water After the problem of slipping on water pipe 1 causes to change water interruption, and hose 9 slips, drainpipe 1, pipeline circle 2 and connecting tube 3 can be fallen In network access case, also need manually to salvage, it is time-consuming and laborious.In order to solve this problem, as shown in Figure 2-5, the one of the utility model In a specific embodiment, locking nut 7 is arranged on the drainpipe 1, the locking nut 7 is equipped with internal screw thread, and one end Opening is big, open at one end small；One end of the hose 9 is equipped with external screw thread；One end that the drainpipe 1 is connected with hose 9 Equipped with baffle 8, the big opening end of the locking nut 7 can cannot pass through the baffle 8 by the baffle 8, small open end；Institute Locking nut 7 is stated to be connected through a screw thread with hose 9.In this way, drainpipe 1 will be set in after hose 9 is connect with drainpipe 1 On locking nut 7 slide at hose 9, and be threadedly coupled with hose 9, thus by the preferably row of being fixed on of hose 9 On water pipe 1, prevent it from slipping from drainpipe 1 during changing water.

It further, as shown in Figures 6 and 7, further include filter, the filter includes casing 4 and sieve 5, the sieve Net 5 is fixed in described sleeve pipe 4, and described sleeve pipe 4 is removably connected with two open ends of the pipeline circle 2.Band The waste water entered in pipeline circle 2 can be first filtered by having the filter of sieve 5, and the solid impurity adulterated in waste water is intercepted Outside pipeline circle 2, avoids solid impurity from being inhaled into pipeline circle 2 and then block drainpipe 1 and hose 9, wherein being directed to waste water The solid impurity of middle variable grain size can choose the filter of different 5 mesh numbers of sieve, and filter operation is more flexible.

Preferably, the filter is threadedly coupled with pipeline circle 2.

Preferably, the filter is inserted into the pipeline circle 2, and the filter and pipeline circle 2 are in transition fit.

Filter is threadedly coupled with pipeline circle 2 or transition fit is connect, can be by dismounting filter after changing water and completing Get off, easy to clean and disinfection, and the different mistake of 5 mesh number of sieve can be replaced according to the granular size of solid impurity in waste water Filter, it is convenient and practical.

Further, as shown in figure 8, the connecting tube 3 is inserted into the interior of one end of the pipeline circle 2 and the pipeline circle 2 Wall is in contact, and multiple holes 6 are equipped on the side wall for the connecting tube 3 being located inside the pipeline circle 2.Pass through connecting tube 3 On hole 6 realize flexibly control drainage rates, the disturbance in drainage procedure to water body is further decreased, conducive to the growth of fry.

Preferably, the drainpipe 1 is Cowhells helix tube or steel wire tube, unsuitable really up to the mark or excessively soft, the drainpipe of drainpipe 1 1 it is really up to the mark when, be not easy to move in net cage, it is inconvenient；When drainpipe 1 is excessively soft, easily deformation occurs during changing water, influences Net cage changes the progress of water.

Preferably, the pipeline circle 2 is pvc pipe.

Specific embodiment of the present utility model is described in detail in conjunction with attached drawing above, but the utility model is not It is limited to the detail of above embodiment, those skilled in the art are in the technical solution of the utility model range Interior made modification, addition or replacement, also belong to the protection scope of the utility model.

It is further to note that in the case of no contradiction, between each different embodiment of the utility model It can also in any combination, as long as it, without prejudice to the thought of the utility model, equally should be considered as disclosed in the utility model Content.
