The utility model provides a bottom drain port of a squid breeding tank, through which all breeding water in the tank can be completely drained. The utility model is composed of a glass with holes, a drainage pipe and a nut, and is characterized in that a piece of glass with holes is used to bond the outer side of the bottom of the breeding tank. The holes of the glass with holes are aligned with the drainage holes at the bottom of the breeding tank. A nut for installing the drainpipe is embedded in the hole of the glass. The upper part of the drainpipe is threaded and screwed into the nut embedded in the glass hole with holes until it is flush with the inner edge of the hole at the bottom of the glass tank and glued to the breeding tank. The underside of the perforated glass at the bottom is also bonded with another perforated glass, and the center of the holes of the above two perforated glasses are aligned, and a nut is adorned on the lower side of the other perforated glass to splice the drainpipe tightly.

Description

Bottom drain of squid breeding tank

technical field

The utility model relates to a drain port of an aquaculture tank, in particular to a drain port of a culture tank used for cultivating squid.

Background technique

Squid is widely distributed along the coast of my country and has high economic value. Due to overfishing and ecological deterioration, since the 1970s, there have been successive declines. Therefore, it is inevitable to carry out artificial breeding. At present, researchers at home and abroad have done a lot of work on squid farming, and have made some progress. However, there are still many problems in the cultivation of its larvae. A large number of scientific experiments need to be carried out as problems such as bait types and environmental factors. In most cases, the above-mentioned experiments will be carried out in small water bodies. Features, become the first choice. Squid, commonly known as cuttlefish, is very easy to spray ink under stress, and its ink has a strong paralyzing effect. If the ink cannot be completely discharged in the aquaculture water body, it will cause damage to the squid itself and cause death. In addition, in the current squid artificial breeding process, the bait used by squid is mostly chilled fish and shrimp. After feeding, the feed will easily sink to the bottom of the pond, which will damage the water quality. And traditional glass cylinder bottom drain all has about 5 millimeters protruding cylinder bottom plane, causes the water in the cylinder to be unable to drain completely. Therefore, need a kind of water outlet that can completely drain the water in the cylinder.

Utility model content

The problem to be solved by the utility model is to provide a bottom drain port of the squid breeding tank, through which all the breeding water in the tank can be completely drained.

The technical scheme of the utility model is composed of a glass with holes, a drainage pipe and a nut, and is characterized in that a piece of glass with holes is used to bond the outside of the bottom of the aquaculture tank, and the holes of the glass with holes are aligned with the drainage holes at the bottom of the aquaculture tank. A nut for installing a drainpipe is embedded in the hole of the holed glass, and the upper part of the drainpipe is threaded and screwed into the nut embedded in the hole of the holed glass until it is flush with the inner edge of the hole at the bottom of the glass tank and glued Also glue another piece of holed glass on the underside of the holed glass at the bottom of the breeding tank, the center of the hole of the above two pieces of holed glass is aligned, and a nut is adorned on the lower side of the other piece of holed glass to splice the drainpipe tightly.

The beneficial effect of the utility model is that the water in the tank can be completely drained, which is beneficial to remove the residue of squid ink and sinking bait, and significantly increases the cleanliness of the squid breeding water body.

Detailed ways

In the present utility model (see accompanying drawing), a piece of perforated glass 2 is glued on the outside of the bottom of the breeding tank 1. The hole of the perforated glass is aligned with the drainage hole at the bottom of the breeding tank. The nut 4 used for the drain pipe, the top of the drain pipe 3 is threaded and screwed into the nut 4 embedded in the hole of the glass hole until it is flush with the inner edge of the hole at the bottom of the glass jar, and the holed glass glued on the bottom of the breeding jar The lower side of 2 is also bonded another piece of perforated glass 5, the center of the hole of above-mentioned two pieces of perforated glass 2,5 is aligned, and the lower side of another piece of perforated glass 5 is adorned with a nut 6 to assemble drainpipe 3 tight.

The diameter of the drain hole that the utility model is set in the small water body culture tank is 5cm; The band glass 2 that is bonded on the outside of the bottom of the culture tank 1 is a square, with a side length of 11 cm and a diameter of 5 cm in the hole; The nut 4 that drainage pipe is installed in the hole of perforated glass 2, the internal diameter of nut 4 is 4cm, and outer diameter is 5cm. Another sheet of perforated glass 5 is a square with a side length of 11 cm and a diameter of 4 cm in the hole. The nut 6 inner diameter that splicing tightly drainage pipe is used is 4cm, and outer diameter is 6cm. The drain pipe 3 has an inner diameter of 3.2cm and an outer diameter of 3.9cm. Since the outer diameter of the drainpipe is 3.9cm, and the diameter of the drain hole at the bottom of the breeding tank is 5cm, the gap between the drainpipe and the drainhole at the bottom of the breeding tank is filled with glass glue, and the upper top of the drainpipe is in contact with the bottom of the glass tank. Along the same level or slightly lower than the bottom of the glass tank 1-2mm, when the water body in the breeding tank is circulating or draining, it can drain 100% of the water in the tank without any residue.

Claims (3)

1. the end discharge outlet of cuttlefish culturing jar, by glass with hole, drainpipe, nut is formed, it is characterized in that adopting a slice glass with hole to be bonded in the outside of culturing jar bottom, align with culturing jar bottom discharge hole in the hole of this glass with hole, in the hole of this glass with hole, be embedded with the nut of the usefulness that fixes a drainpipe, drainpipe top is shaped on and is threaded in the nut of setting in the glass with hole hole, until with glass jar bottom hole in along concordant, be bonded in also bonding another sheet glass with hole of downside of the glass with hole of culturing jar bottom, the hole center-aligned of above-mentioned two glass with hole, the downside of another sheet glass with hole are adorned a nut and drainpipe are pieced together tight.
