Artificial fish reef bottom sowing planting device

Abstract

The invention relates to an artificial fish reef bottom sowing planting device. The artificial fish reef bottom sowing planting device comprises an inner-layer device, an outer-layer device sticking close to the inner-layer device, and a heavy punch for separating the outer-layer device from the inner-layer device, wherein the inner-layer device comprises a bottom-layer steel disk positioned at the bottom end, a top-layer steel disk positioned at the top end, a steel bar handle fixedly connected with the top-layer steel disk, a rope connected with the steel bar handle, and a reinforcing bar; the upper and lower ends of the reinforcing bar are fixedly connected with the top-layer steel disk and the bottom-layer steel disk respectively; the outer-layer device comprises a steel sleeve, two steel bars arranged symmetrically, and a middle perforated steel sheet; the lower ends of the two symmetrically-arranged steel bars are fixedly connected with the steel sleeve, and the upper ends of the two symmetrically-arranged steel bars are fixedly connected with the middle perforated steel sheet; the inner side of the bottom end of the steel sleeve is provided with an elastic steel sheet. The artificial fish reef bottom sowing planting device has the beneficial effects that bottom sowing of artificial fish reef seeds in very deep sea areas can be completed on a ship on the sea surface, and the device is high in safety, and easy and convenient to operate.

Description

technical field [0001] The invention relates to a device for sowing seedlings at the bottom of an artificial fish reef. Background technique [0002] Artificial fish reefs are structures artificially set up in the sea. The purpose is to improve the ecological environment of the sea area, create a good environment for marine organisms to inhabit, and provide places for fish to reproduce, grow, bait, and shelter enemies, so as to achieve protection and multiplication. and to increase catches. At present, the construction of artificial reefs has been widely carried out at home and abroad, and the restoration of offshore marine habitats and fisheries has been carried out, and good results have been achieved. In China, aquatic products are deeply loved by people and play an important role in daily life. With the continuous improvement of people's living standards, the demand for aquatic products is also increasing, and higher requirements are put forward for product quality and...
