[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Example 1:

[0025] like Figure 1-Figure 5 As shown, this embodiment provides an aquaculture cage attachment removal device, comprising a floating bin 1 and two guide rods 9. A vent hole 11 communicating with an inner cavity of the floating bin 1 is provided at the bottom axis thereof. An air guide device 4 is installed on the floating bin 1. A conical counterweight 2 is fixedly installed on the lower side of the outer surface of the floating bin 1. Two guide rings 8 sliding with the two guide rods 9 are symmetrically installed on both sides of the upper portion of the outer surface of the floating bin 1. Four threaded rods 3 are symmetrically installed in pairs at the bottom end of the floating bin 1 away from the axis thereof. A connecting assembly 5 is installed between the two symmetrical threaded rods 3, and a flushing assembly 7 is installed on the connecting assembly 5.

[0026] During actual use, the air guide device 4 is used to control the sinking and floating of the floating bin 1, thereby adjusting the operating height of the flushing component 7 below the floating bin 1 for spraying and flushing. In this way, when cleaning the net cage, comprehensive coverage and no dead angles of the cleaning work can be ensured. By setting the connecting component 5 to cooperate with the four threaded rods 3, the spraying direction of the flushing component 7 can be changed, which is convenient for the user to adjust the spraying direction of the flushing component 7 during the cleaning operation.

[0027] Furthermore, in order to prevent the flushing component 7 from causing the device to tilt or move during the spraying process, before use, the two guide rods 9 need to be inserted into the bottom of the breeding pond, and then the two guide rings 8 symmetrically installed on the counterweight 2 are inserted into the guide rods 9 for limiting, so as to prevent the device from moving unnecessary during use.

[0028] Example 2:

[0029] The only difference between this embodiment and embodiment 1 is that the air guide device 4 includes an electric cylinder 41 and a plurality of reinforcing ribs 42. The electric cylinder 41 is fixedly mounted at the axis of the top of the floating chamber 1. The plurality of reinforcing ribs 42 are respectively mounted on the outer surface of the electric cylinder 41, and the ends of the plurality of reinforcing ribs 42 away from the electric cylinder 41 are respectively fixedly connected to the top of the floating chamber 1.

[0030] Furthermore, the output shaft of the electric cylinder 41 extends into the inner cavity of the floating warehouse 1, and the output shaft of the electric cylinder 41 is fixedly connected to the connecting rod 43 through a coupling. A sliding block 44 is fixedly installed on the bottom end of the connecting rod 43, and a rubber ring 45 that is compatible with the inner cavity of the floating warehouse 1 is glued to the outer surface of the sliding block 44.

[0031] The electric cylinder 41 is started. The output shaft of the electric cylinder 41 drives the sliding block 44 to move up and down through the connecting rod 43. The outer surface of the sliding block 44 is glued with a rubber ring 45 that adapts to the inner cavity of the floating chamber 1. When the electric cylinder 41 drives the sliding block 44 upward, water is sucked into the inner cavity of the floating chamber 1 through the vent 11. As a result, the weight in the inner cavity of the floating chamber 1 increases, causing the entire device to sink.

[0032] On the contrary, when the electric cylinder 41 drives the sliding block 44 downward, the sliding block 44 pushes the water in the inner cavity of the floating bin 1 out of the inner cavity of the floating bin 1, so that a vacuum state is formed in the inner cavity of the floating bin 1, causing the entire device to float. In this way, the electric cylinder 41 is set to control the sliding block 44 to make the device sink or float.

[0033] Example 3:

[0034] The only difference between this embodiment and embodiment 1 or 2 is that the connecting assembly 5 includes a connecting plate 51. Four slip rings 52 are symmetrically mounted on both sides of the back end of the connecting plate 51 away from the middle, and slide with the two threaded rods 3. A penetrating mounting hole 53 is opened in the middle of the front end of the connecting plate 51.

[0035] The outer surfaces of the two threaded rods 3 are both threadedly mounted with threaded rings 6, and the two threaded rings 6 are both located below the two lowermost slip rings 52;

[0036] During use, the flushing assembly 7 is slidably installed on the two symmetrical threaded rods 3 through the connecting plate 51, so that the spraying direction of the flushing assembly 7 can be changed according to the needs of use. After the connecting plate 51 is inserted into the threaded rod 3, the threaded ring 6 is threadedly installed on the outer surface of the threaded rod 3 so that it is limited by the slip ring 52 to prevent the connecting plate 51 and the threaded rod 3 from slipping off.

[0037] Furthermore, the flushing assembly 7 includes a jet seat 71, which is fixedly mounted on the inner surface of the mounting hole 53. The front end of the jet seat 71 is open, and a fixing frame 72 is fixedly mounted in the middle of the back end of the jet seat 71. A high-pressure pump 73 is fixedly mounted on the fixing frame 72. A plurality of connecting water pipes 74 connected to the inner cavity thereof are mounted in a circular array on the outer surface of the jet seat 71. The ends of the plurality of connecting water pipes 74 away from the jet seat 71 are all connected to the output end of the high-pressure pump 73.

[0038] A fixing ring 711 is fixedly mounted on the inner port of the injection seat 71. A rotating rod 712 is fixedly mounted in the middle of the inner end wall of the injection seat 71. A rotating plate 713 is rotatably mounted on the side of the rotating rod 712 away from the inner end wall of the injection seat 71, and rotates with the fixing ring 711. The rotating plate 713 is provided with a circular array of penetrating injection holes 715. A plurality of guide plates 714 are fixedly mounted in a circular array on the side of the rotating plate 713 close to the inner end wall of the injection seat 71.

[0039] During operation, water is sucked in by a high-pressure pump 73 and delivered to the inner cavity of the spray seat 71 through a plurality of connecting water pipes 74. As the amount of water in the inner cavity of the spray seat 71 increases, the pressure in the inner cavity of the spray seat 71 increases, and the water in the inner cavity is sprayed out through a plurality of spray holes 715 at high pressure, thereby spraying and flushing away the attachments on the cage;

[0040] After the multiple connecting water pipes 74 spray water into the inner cavity of the spray seat 71, the water pushes the guide plate 714 to cause the rotating plate 713 to rotate. When the rotating plate 713 rotates, the multiple spray holes 715 are driven to transmit together, thereby expanding the spray range of the multiple spray holes 715.

[0041] It should be noted that the specific installation method, circuit connection method and control method of the electric cylinder 41 and the high-pressure pump 73 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
