a benthos collection system suitable for deep water areas comprises a recovery rope, a collection cage, a food box, an anti-sinking iron sheet and a suspended heavy object; the recovery rope and three haulage ropes are connected to the ring, and the other end of haulage rope is connected on collection system's ring arch, collection system upper portion is open structure, the cage lid can be opened, cover 40 mesh stainless steel screen cloth on the circular lateral wall, and there is the lateral wall opening on the circular lateral wall, be equipped with the food box on the collection system bottom, food is put into the food box through the food lid at food box top, the suspension rope is connected to collection system bottom lower extreme, connect the anti-trap iron sheet through fixed perforation, the suspension rope passes fixed perforation, connect and hang the heavy object. The recovery rope is used for recovering the benthos collection device; the collecting cage is used for being thrown into water to collect benthos and comprises a bottom surface and a side wall; the food box is positioned at the bottom in the collecting cage; the anti-sinking iron sheet is positioned below the collecting cage to prevent the collecting cage from sinking into the sediment and losing the effect; the suspended heavy object is positioned below the anti-sinking iron sheet, so that the collecting cage can be submerged into the water bottom of a deep water area.

The recovery rope is a tool for connecting workers to the benthos collecting device, and the nylon binding rope is optimally selected.

The collecting cage is of a cylindrical structure, the size of the collecting cage is 18-24cm, and the height of the collecting cage is 25-3535 cm; the top of the collecting cage is provided with an openable cage cover, and an operator can take out a sample in the collecting cage through the cage cover.

The side wall of the collecting cage is of a water leakage net structure; the water leakage net adopts a stainless steel screen mesh with 40 meshes.

The food box is provided with a food box cover which is a device for placing the phagostimulant.

The utility model has the advantages that:

the device adopts a cage-shaped structure, the cage-shaped structure is cylindrical and comprises a bottom surface and a circular side wall, the circular side wall adopts a water leakage net design, an opening design is favorable for the entrance of benthonic organisms, but the benthonic organisms cannot freely enter and exit, and meanwhile, the structure avoids the problem that the device is overweight due to water accumulation during recovery; the weight is hung, so that the collecting device is completely submerged in the water bottom; the anti-sinking iron sheet can ensure that the collecting device cannot be sunk into mud; the utility model discloses the device can ensure that collection system sinks into the bottom and does not sink into mud, and the net that leaks can ensure device recovery time extravagant manpower and material resources, has improved the rate of accuracy of sampling greatly.
