Description

TECHNICAL FIELD

[0001] The present application relates to the field of industrialized aquaculture of aquatic products, and particularly to an offshore cage automatic cleaning device. BACKGROUND

[0002] Raft culture of shellfish has been widely used in China due to its advantages of convenient management, low cost, high yield and fast growth. The shellfish raft culture cage includes a long cylindrical net and a plurality of equally spaced partition plates arranged in the net, and a weight is arranged below the net. The net is connected to the edges of the partition plates by a fishing line. When culturing scallops, the scallop seedlings are placed on each rubber partition plate, and then the opening of the net is sewn to allow a certain number of scallop seedlings in each partition. After the scallop seedlings grow in the sea, the scallop culture cage is salvaged from the sea, and the scallops are taken out. During the culture process, the cage is immersed in water for a long time, which causes the rapid proliferation of filamentous algae and other attachments on the cage. These biological attachments block the mesh and compete with shellfish for food, causing shellfish to die of oxygen deficiency. The attachments also increase the weight of the cage, affecting the wind and wave resistance of the raft. If not cleaned in time, many other shellfish and algae will be adsorbed on the salvaged scallop culture cage during harvesting. The adhesion of these shells and algae to the scallop culture cage is very dense and strong, and it is difficult for humans to separate the shells and algae from the scallop culture cage. Traditional cage cleaning usually involves stacking the salvaged cage for fermentation, then washing it with water, and then crushing and beating the attachments after drying. This cleaning method has the disadvantages of long interval time, affecting scallop growth, multiple steps, long time consumption, high labor cost, bacterial growth, unpleasant odor, serious pollution, and poor cleaning effect. In addition, there is a net scraping method to prevent the attachment of attachments. The net scraper on the cage can move up and down on the cage by using the waves generated by the tide to avoid the attachment of dirty substances. This prevention method has the disadvantages of unsatisfactory cleaning effect, being greatly affected by the environment, many uncertain factors, and low intelligence.

[0016] The specific embodiment of the present application will be described below in combination with the drawings. As shown in the drawings: an offshore hanging cage automatic cleaning device is composed of a hull part and a cleaning part, Figures 1 to 5

[0017] The hull part includes a hull 1, the hull 1 is provided with a tail propeller 2, the hull 1 is also provided with a pair of symmetrically distributed winch mechanisms 3, the two output shafts 4 of the winch mechanisms 3 are each wound with a rope 5, a pair of slide grooves 6 distributed along the width direction of the hull 1 is arranged in matching with the winch mechanisms 3, the slide grooves 6 are slidably connected with the slip rings 7, the rope 5 on the output shaft 4 is movably threaded in the corresponding slip ring 7, and the bottom end of the rope 5 is connected with the cleaning part, and the bottom surface of the hull 1 is also provided with an underwater camera 8,

[0018] The cleaning part is composed of two parts of left half and right half which are same in structure and symmetrically distributed, the left half includes a semi-annular water spraying shell 9 which is communicated with the water outlet of a submersible pump 10 through a pipeline, the submersible pump 10 is fixedly arranged on a support frame 11, the support frame 11 is provided with folding legs 12 on both sides, the water spraying shell 9 is provided with a plurality of water spraying columns 13 which are communicated with the inner cavity of the water spraying shell 9, the inner side of the water spraying column 13 is provided with a water spraying hole, the top ends of all the water spraying columns 13 are connected with a semi-annular supporting plate 14, the inner side of the semi-annular supporting plate 14 is provided with brush 15, and a longitudinally distributed guide strip 16 is further arranged between the water spraying shell 9 and the semi-annular supporting plate 14, the both ends of the guide strip 16 are provided with arc-shaped guide portions 17, the end surface of the semi-annular supporting plate 14 is further provided with an electromagnet, and the top end surface of the semi-annular supporting plate 14 is provided with a lifting ring 18, the rope 5 is connected to the lifting ring 18,

[0019] The ship body 1 is provided with a plurality of driving cylinders 19 corresponding to the plurality of slip rings 7 respectively, and the working end of the driving cylinder 19 is connected with the slip ring 7.

[0020] All the above-mentioned electric actuators are powered by the storage battery arranged on the ship body 1.

[0021] The working process of the offshore cage automatic cleaning device is as follows: the staff uses the remote control device to send a signal to the control system arranged on the ship body 1, the control system controls the motor to work, the tail propeller 2 drives the ship body 1 and the cleaning part connected below to sail in the sea area where the cage is bred, during the sailing process, the ship body 1 travels above the net cable on which the cage 20 is hung, and the underwater camera 8 collects the underwater picture in real time and transmits the picture to the control system of the device, the image recognition system in the control system identifies and judges the picture information, when the image recognition system judges that the ship body 1 moves to the working position of the target cage, it will first send a signal to the control system, the control system controls the tail propeller 2 to stop working, at this time, the cleaning part below the ship body 1 will contact the cage hung below the rope, under the action of the cleaning part, the ship body 1 stays at the current position.

[0022] The control system de-energizes the electromagnet, and the electromagnet no longer exhibits magnetism. Under the pulling action of the rope 5, the left half and the right half of the cleaning part are separated from each other. Since the left half and the right half are both designed in a semicircular shape, the two separated parts will hover on both sides of the cage 20. After the time relay in the control system calculates that the electromagnet has been de-energized for a sufficient time (sufficient for the left half and the right half to adhere to both sides of the cage 20 and remain substantially stationary), the control system controls the driving cylinder 19 to work, driving the sliding ring 7 to move towards the central axis of the ship body 1. The movement of the sliding ring 7 will drive the rope 5 to move inward, and the left half and the right half will move closer to each other. At the same time, the control system controls the electromagnet to be energized. After the electromagnet exhibits magnetism, the left half and the right half that are close to each other are attracted to each other and become an integrated structure again. At this time, the cleaning part is sleeved outside the cage 20, and the preparation work is completed.

[0023] Then the control system controls the two submersible pumps 10 to work. The submersible pumps 10 pump seawater into the water spraying shell 9 that has been connected into a complete circular ring, and finally the seawater is sprayed out through the water spraying holes on the multiple water spraying columns 13 above the water spraying shell 9. The water body is sprayed on the surface of the cage 20 to achieve the purpose of cleaning the cage 20. In actual design, in order to obtain better cleaning effect, the water spraying holes can be provided in multiple, or the water spraying holes can be inclined to ensure that the water flow is sprayed along the tangent direction of the cylindrical cage 20.

[0024] At the same time of water spraying and cleaning, the control system also controls the winch mechanism 3 to work. The output shaft 4 of the winch mechanism 3 drives the rope 5 to pull the entire cleaning part to move along the length direction of the cage 20. After the cage 20 moves from top to bottom and then from bottom to top back to the initial position, the bristles 15 inside the semicircular support plate 14 will wash the outer surface of the cage 20, that is, the cleaning operation of the target cage 20 is completed.

[0025] After the cleaning is completed, the control system controls the sliding ring 7 to move outward again, and the electromagnet is de-energized. The left half and the right half are separated again. The ship body 1 moves towards the next cage 20, and the above operation is repeated at the next cage 20 to achieve the cleaning operation of the next cage 20.

[0026] When all the cages 20 on one net cable are completely cleaned, the operator can control the ship body 1 to sail to the next net cable through the remote control device, and repeat the above operation until all the cages 20 on all the net cables are completely cleaned.

[0027] In a non-use state, the folding legs 12 in the cleaning part can be opened. The folding legs 12 can prevent the cleaning part from toppling over.
