Detailed Description
In order to describe the technical contents, the achieved objects and effects of the present utility model in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.
Referring to fig. 1-2, a drainage device of a sea water shellfish larva seedling attaching pond comprises a filter screen 1, a weakening pipe 2 and a suction pipe 3;
the filter screen 1 is arranged in the seedling attaching pool, the filter screen 1 is barrel-shaped, and the weakening pipe 2 is erected in the middle of the inside of the filter screen 1 and is arranged at intervals with the inner wall of the filter screen 1; the wall of the weakening tube 2 is provided with a plurality of through holes 21;
the end of the suction tube 3 is arranged inside the weakening tube 2.
From the above description, the beneficial effects of the utility model are as follows: in the drainage device of the sea water shellfish larva seedling attaching pond, water in the seedling attaching pond is filtered by the filter screen 1 and then pumped away by the suction pipe 3, so that the difficulty and trouble that the shellfish larva is sucked into the suction pipe 3 to cause the subsequent shellfish larva to be put back into the seedling attaching pond are avoided.
The suction end of the suction pipe 3 is arranged in the weakening pipe 2, the weakening pipe 2 and the through holes 21 on the weakening pipe 2 are beneficial to average and dispersion of suction force of the suction pipe 3, and further, the outer circumference of the filter screen 1 is far away from the suction pipe 3, so that shellfish larvae at the outer circumference of the filter screen 1 are subjected to smaller suction force, and damage to the shellfish larvae is avoided.
Further, the filter screen 1 further comprises a floating ball 4, and the floating ball 4 is connected with the filter screen.
As can be seen from the above description, the buoyancy provided by the floating ball 4 makes the filter screen 1 suspend on the water surface of the spat attaching pond, and the shellfish larva tends to sink on the bottom of the spat attaching pond, so that the filter screen 1 is on the water surface to avoid the suction pipe 3 from adsorbing the shellfish larva.
Further, the filter screen comprises connecting strips, wherein a plurality of floating balls 4 are arranged, and the floating balls 4 are connected with the filter screen 1 through the connecting strips and are arranged at intervals with the filter screen 1; the plurality of floating balls 4 evenly encircle the outer circumference of the filter screen 1.
As is apparent from the above description, the above arrangement stabilizes the state of the screen 1 in the spat pool and prevents the floating ball 4 from sticking to the screen 1 to block water from entering the screen 1.
Further, a valve 7 is arranged on the suction pipe 3.
As is evident from the above description, the valve 7 is used to activate or deactivate the pumping of the suction tube 3.
Further, the seedling pool further comprises a hanging rope 5 and a connecting piece 6, wherein two ends of the hanging rope 5 are respectively connected to the upper edge of one side of the seedling pool, one side of the connecting piece 6 is connected to the top of the filter screen 1, and the other side of the connecting piece is connected to the hanging rope 5.
As can be seen from the above description, the filter screen 1 needs to be maintained and replaced after being used for a period of time, and a worker can disconnect the hanging rope 5 from the seedling attaching pool, and drag the filter screen 1 out of the seedling attaching pool through the hanging rope 5.
Example 1
Referring to fig. 1-2, a drainage device of a sea water shellfish larva seedling attaching pond comprises a filter screen 1, a weakening pipe 2 and a suction pipe 3;
the filter screen 1 is arranged in the seedling attaching pool, the filter screen 1 is barrel-shaped (one end of the filter screen can be provided with an opening, as shown in figure 1, the bottom wall and the side wall of the filter screen are both provided with filter holes), and the weakening pipe 2 is erected in the middle of the inside of the filter screen 1 and is arranged at intervals with the inner wall of the filter screen 1; the wall of the weakening tube 2 is provided with a plurality of through holes 21;
the end of the suction tube 3 is arranged inside the weakening tube 2.
The filter screen 1 is characterized by further comprising a floating ball 4, wherein the floating ball 4 is connected with the filter screen 4.
The filter screen comprises a filter screen body, a plurality of floating balls 4, a filter screen 1 and a connecting strip, wherein the plurality of floating balls 4 are arranged; the plurality of floating balls 4 evenly encircle the outer circumference of the filter screen 1.
The filter screen 1 is vertically arranged, the weakening tube 2 and the filter screen 1 are coaxially arranged, and a plurality of through holes 21 are uniformly arranged around the axis of the weakening tube 2. The filter screen is detachably connected with the weakening pipe through bolts, so that the filter screens with different filter hole sizes can be conveniently replaced according to the sizes of shellfish seedlings.
The use and principle of the drainage device of the sea water shellfish larva seedling attaching pond provided by the embodiment are as follows:
the worker starts the suction pipe 3, and the suction pipe 3 sucks and adsorbs pool water of the seedling pool. Since the suction end of the suction tube 3 is provided in the weakening tube 2, the wall of the weakening tube 2 prevents the suction force of the suction tube 3 from concentrating in one direction to absorb water, and the through holes 21 of the weakening tube 2 uniformly disperse the suction force of the suction tube 3 in all directions (the weakening tube 2 is equivalent to weakening the suction force of the suction tube 3 without affecting the water absorption amount of the suction tube 3). And because the outer circumference of the filter screen 1 is spaced from the weakening tube 2, the suction force applied to the outer circumference of the filter screen 1 is small. The floating ball 4 enables the filter screen 1 to be suspended on the water surface of the seedling attaching pool.
The arrangement avoids damage to shellfish larvae caused by excessive suction of shellfish larvae by the suction tube 3.
The setting of filter screen 1 separates shellfish larva outside suction tube 3, and after suction tube 3 stopped the motion, shellfish larva can return the bottom of the pond of attaching the seedling pond naturally.
