It will be appreciated that the maximum buoyancy provided by buoyancy tank 4 is greater than the weight of the fishing apparatus 100 as a whole to ensure that recovery of the fishing apparatus 100 can be achieved by buoyancy tank 4, in the event that there is no water injection inside buoyancy tank 4.

It can be understood that the hose assembly 1 is good in material sealing performance and corrosion-resistant, can be placed in seawater for a long time, and the hose assembly 1 is adopted to convey the caught fishes, so that the hose is convenient to carry, the hose can adapt to the environment in seawater, and the material is softer, so that the damage to the fishes is caused when the fishes are prevented from impacting the inner wall of the hose assembly 1. And the hose assembly 1 has certain rigidity, so that the hose assembly 1 has certain external force impact resistance, and meanwhile, large disturbance can not occur under the action of external force, and the fishing effect can not be greatly influenced.

In one embodiment of the invention, the length of the section of the first hose 101 above the buoyancy tank 4 is adjustable.

In this embodiment, as shown in fig. 1, the buoyancy tank 4 is located on the first hose 101, by adjusting the buoyancy of the buoyancy tank 4, the buoyancy tank 4 floats up or submerges to adjust the position of the first hose 101 in the seawater, one section of the first hose 101 located above the buoyancy tank 4 is set to be adjustable in length, so that when water is added into the buoyancy tank 4 and submerges, one section of the first hose 101 located above the buoyancy tank 4 is elongated, the overall length of the first hose 101 is increased, so as to reach a position deeper in the seawater, when water inside the buoyancy tank 4 is discharged, the buoyancy of the buoyancy tank 4 is increased, the buoyancy is floated, one section of the first hose 101 located above the buoyancy tank 4 is shortened, so that the overall length of the first hose 101 is shortened, the position shallower in the seawater is reached, and the recovery is facilitated. Need not to add other complicated mechanisms and adjust the position of fishing device 100, energy-concerving and environment-protective, and when adjusting first hose 101 length, can not influence the position of other equipment of connecting in first hose 101, improved the stability of fishing operation.

Due to the suction effect provided by the vacuum pump 202, the second hose 103 and the first hose 101 which are positioned in front of the vacuum pump 202 are pumped into a vacuum state, a pressure difference is formed between the second hose and the seawater, the flow rate of the seawater at the joint of the fish sucking cover 201 and the first hose 101 is accelerated, the flow field at the position is changed, the fishes are easily sucked into the first hose 101, and the cover surface of the fish sucking cover 201 prevents the fishes from escaping to the two sides, so that the fish sucking efficiency is further improved.

It can be understood that the fish sucking cover 201 is a conical cover, and the end with the smaller diameter of the conical cover is connected to the first hose 101, so that the arrangement is matched with the suction force of the vacuum pump 202, the flow field of the seawater near the conical cover is changed, more fish can be gathered, and the fish sucking efficiency is improved.

It can be understood that the vacuum pump 202 sucks the fishes and the seawater together and transmits the fishes and the seawater to the sorting mechanism, the vibration of the vacuum pump 202 during operation is small, the culture area in the ship body cannot be affected, and the fish scratching situation of the traditional bucket pump can be avoided.
