Problems solved by technology

[0007] The multiple round-trip operations of the ship not only increased labor costs, but also consumed a large amount of diesel oil and emitted a large amount of carbon dioxide. During the entire process of cleaning on the shore , a large number of decayed attachments will bring new pollution to the sea area

Embodiment Construction

[0020] exist figure 2 In 2-1, the up and down positions of buoyancy ball (1), raft body (2), suspension rope (3), net cage (4) are all determined by the sea surface.

[0021] This device is affected by gravity when the seawater is at high tide, and is pulled down by the hanging object (10), and the ring-shaped hollow float net brush moves to the bottom of the net cage from the top of the net cage (see figure 2 2-1 in).

[0022] figure 2 2-2 among represents that when the seawater ebbs, the hanging object (10) falls into the seabed, and the ring-shaped hollow float net brush is not affected by the gravity of the hanging object (10), and moves upwards to the top of the cage by buoyancy.

[0023] Generally, the tidal range in the breeding sea area is more than 5 meters, and the length of the net cage is generally about 1.5 meters. The tidal range can fully meet the stroke requirements of the ring-shaped hollow float net brush. The tide rises and falls twice a day, which can...

Abstract

The invention relates to a device for automatically washing a net cage under water in agriculture, which relates to the underwater automatic washing of a net cage in agricultural and marine floating-raft net-cage cultivation. A ring-shaped hollow floater is sleeved on a net cage, the inner ring part of the ring-shaped hollow floater is provided with a [-shaped groove, a strip brush with an E-shaped section of a soleplate is inlaid into the groove to enable the strip brush and the groove to become a part, i.e. the ring-shaped hollow floater net brush, the inner ring part of the ring-shaped hollow floater is provided with four uniformly distributed round holes which are respectively tied to four pull ropes so as to be connected with positioning rise-stopping rings, and the lower surfaces of the positioning rise-stopping rings are connected with a hung object to from a device through hanging ropes. The up-and-down motion for the net cage can be realized by the ring-shaped hollow floater net brush by means of the change of tides and the up-and-down fluctuation of waves to achieve the purpose of washing the net cage. The invention has the advantages that the agricultural standardized production level is improved, the floating-raft net-cage cultivation cost is lowered, the pollution-free healthy growth of cultivated objects is promoted, and energy saving, emission reduction, labor saving, environmental protection and remarkable effect are realized.

Description

[0001] The application date of this application is: June 5, 2008, the priority date: August 29, 2007, the application number of the invention patent application with 200810108975.0, the original application for invention creation name: waves and wanderersMethods and devices of automatic cleaning of net cages. Technical field [0002] The invention involves agricultural and sea floating raft net cages. The method and device of automatic cleaning at any time under the water under the water. technical background [0003] At present, after the sea -floating raft net cage farming, after a period of time in the cage, some of the offshore marine creatures settled on the wall of the breeding net cage to become dirty.Where to exercise, breathing, and excretion, compete for bait with farmers, and block the net cage, causing the trend to slowly or indiscriminate, causing the farmers to lack bait to die. Therefore, these dirt must be removed regularly.At present, pouring cages is the best w...
