Description

The net cage equipment of removing contamination under water

Technical field the utility model is the Clean-net cage of the cage netting netting gear equipment of removing contamination under water in a kind of aquaculture industry, belongs to the fishery machinery apparatus field.

In the background technology marine industry in order to carry out the circle of fish, enclose, block, supporting to wait needs, must in water, lay the etting netting gear so that aquatic animals such as fish are implemented corral, the cycle of aquaculture is generally longer, the etting netting gear needs the long period to be immersed in the water, this provides good adherance for the growth of various algae and other biology, the inside and outside water body exchange to net circle of being on the increase of attaching organism has constituted and has seriously influenced on the etting netting gear, cause the water quality corruption, water body environment worsens, a series of problems such as the stressed distortion of net cage shape, therefore must effectively remove the attaching organism of dirty network blocking tool mesh, at present public use a kind of be used to remove boats and ships under water the equipment of rigidity surface attachments with a simple rotating brush job, this equipment will clean very and is difficult to carry out laying underwater flexible etting netting gear, another kind of maneuver is manual cleaning, by ship berthing at etting netting gear side, operating personnel are hand-held long brush, to object cleaning under water, this mode is simple, but labour intensity is big, the cleaning weak effect, also having a kind of method is to utilize high-pressure hydraulic pump to make high-velocity flow, during operation the hydraulic giant spout being aimed at position to be cleaned washes away, this equipment is to utilize current to promote cleaning brush to clean the etting netting gear simultaneously, during using, reality in water, can be subjected to powerful fluid resistance owing to jet, it is relatively more difficult again that spout is accurately aimed at the cleaning position, therefore be greatly limited in using, under some special environment, also once adopt the diving personnel to dive and implemented the method for cleaning under water, but the difficulty of operational administrative is very big, is difficult to extensive employing.

The deficiency that the utility model content exists at existing equipment, the purpose of this utility model provides a kind of novel net cage equipment of removing contamination under water, solve the problem that fish culture net cage etting attachment cleans under water, the net cage equipment of removing contamination under water is by submersible machine [1], transmission mechanism [6], hairbrush assembly [3] and underwater platform [2] order connect to be formed, one end of submersible machine [1] and transmission mechanism [6] connects, the output of two groups of reciprocal rotations of transmission mechanism [6] and about two hairbrush assemblies [3] link, submersible machine [1], transmission mechanism [6] and hairbrush assembly [3] are installed in the prismoid of underwater platform [2], submersible machine [1] is equipped with impeller [9] at its a end, the installation site of the brush head [7] in the hairbrush assembly [3] should make brush head [7] when rotated, the rotational trajectory line of its outer rim protrudes in the bottom surface of underwater platform [2], specifically be on a underwater platform [2] that can hang onto underwater operation, arranging one group of brush assembly, this brush assembly is driven by a submersible machine [1], submersible machine [1] axle one end is connecting a transmission mechanism [6], transmission mechanism [6] has the worm gear one [12] of two different rotary directions, worm gear two [16], be connected with hairbrush assembly [3] respectively separately by worm-wheel shaft [8], when exercisable underwater platform [2] when hanging onto underwater operation, brush head [7] is finished sweeping on etting [21] plane under the drive of motor [1] under water, attachment on the cleaning etting [21], the other end of submersible machine [1] axle is connecting an impeller [9], impeller [9] is high speed rotating under the drive of motor [1] under water, promote underwater platform [2] and be close to etting [21], cause underwater platform [2] impingement flow backward simultaneously, thing in the dirt that eliminating is gone up under the brush from etting [21], can a storage bag be installed at impeller [9] rear portion, thing in the dirt that is used to collect under the brush.

Underwater platform [2] motor [1] under water drives down, brush head [7] is done the round brush motion on etting [21] plane, thing by brush head [7] and the dirt that the mechanical brushing of etting [21] is removed on the etting [21], the brushing direction of last row's hairbrush assembly [24] and following row's hairbrush assembly [22] is opposite, its exercising result makes etting [21] be tension, help the smooth expansion of etting [21], solve the problem that kinks of flexible member, underwater platform [2] advances with impeller [9] simultaneously, by being attached on etting [21] plane, can increase the effect of brush head [7] brushing, improve the effect of removing contamination, can solve the problem that fish culture net cage etting attachment cleans under water.
