When the culture ship 10 and the auxiliary ship body 20 need to be fixed, the connecting sleeve body 73 and the auxiliary ship body 20 are clamped and fixed and then connected with the electromagnet 77 through the elastic piece 71, the electromagnet 77 is electrified to have magnetic force to adsorb the ship body of the culture ship body 10, so that the culture ship 10 and the auxiliary ship body 20 are fixed, and when the culture ship needs to be loosened, the power supply of the electromagnet 77 is disconnected.

Example 5:

the utility model discloses a throw the material experiment and throw material mechanism 30 to embodiment 1 and throw the material experiment, as experimental group, throw the material experiment and go on in the basin, the water in the basin is the sea water, temperature range control is at 25 ℃ 2 ℃, choose the fodder that the particle diameter is 1.5mm for use to throw the material experiment, simulate sea surface environment, through fan simulation sea surface sea wind, establish in addition that the contrast group adopts the manual work to throw the material mode and throw the material, throw the material condition unanimous with experimental group, only throw the material mode different. The loss rate and the settling velocity of the feed in water are obtained by measuring in the feeding process, whether the feed is fed to exceed a feeding area or not is observed, the loss rate of the feed fed by an experimental group and a control group in water is shown in figure 8, the settling velocity of the feed fed by the experimental group and the control group in water is shown in figure 9, the experimental group and the control group are observed to have no condition that the feed falls out of a feeding range, the control group has the condition that a small part of feed is not in the feeding area under the condition that the simulated wind power is small, and the condition that the feed floats out of the feeding area occurs in the feeding process after the simulated wind power is increased. Can know through throwing the material experiment the utility model discloses a throw material mechanism 30 can realize accurate throwing the material, and effectively reduce the solution loss rate of fodder, and settling velocity is lower.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
