DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments, and the following embodiments do not limit the invention involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required for the solutions of the invention.

[0023] It should be understood by those skilled in the art that all directional references (e.g., above, below, upward, up, down, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to aid the reader's understanding and do not represent limitations (e.g., to position, orientation, or use, etc.) on the scope of the present invention as defined by the appended claims. In addition, the term "substantially" may refer to slight inaccuracies or slight deviations of conditions, amounts, values, or dimensions, etc., some of which are within manufacturing deviations or tolerances.

[0024] Embodiment 1

[0025] like Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, a marine aquaculture device includes a breeding cage, the breeding cage has an inner and outer double-layer net 1, an intermediate brush body 2 is arranged between the double-layer nets, the intermediate brush body is provided with bristles that can contact the net, an inner brush body 3 is arranged on the inner side of the inner net corresponding to the intermediate brush body, and an outer brush body 4 is arranged on the outer side of the outer net, the inner brush body and the outer brush body are provided with bristles that can contact the net, the intermediate brush body has ferromagnetic material, such as iron, the inner brush body and the outer brush body are provided with magnets 5, so that the intermediate brush body, the outer brush body and the inner brush body attract each other and rise and fall synchronously, the inner brush body and the outer brush body are towed by a trolley 6 located on the upper part of the breeding cage through a traction rope 601, and the trolley is provided with a traction rope retracting device, such as a winch, and the intermediate brush body, the outer brush body and the inner brush body move up and down, so as to clean the net. The magnet is an electromagnet to facilitate the control of attraction or separation with the intermediate brush body. The trolley can move on the upper part of the net cage. For example, a track 7 for the trolley to travel is arranged above the net cage.

[0026] The breeding cage is circumferentially provided with spacers 8, which are equivalent to the support columns in the upper and lower directions of the cage, and an intermediate brush body is arranged between two adjacent spacers.

[0027] An observation device capable of observing the water area above the adjacent spacers is provided below the trolley, such as a camera 9. If the inner net is damaged, the fish in the net cage will enter between the inner and outer nets, and if the outer net is damaged, the fish outside the net cage will enter between the inner and outer nets. Therefore, the inner brush body rises to drive the fish or other marine life that enter upwards so that they can be observed by the camera provided below the trolley, so that the net can be repaired in time to avoid damage to both the inner and outer nets.

[0028] There are conical holes distributed from top to bottom between two adjacent spacers, the top holes of the conical holes face upwards, and the conical holes include two opposite plates 10, the ends of the two plates are respectively connected to the spacers on both sides by rotation, and the plates are connected to the same control rope 11, and the control rope is lifted or lowered by the traction device above the breeding cage. The spacer between the upper and lower adjacent plates connected to the same spacer is provided with a guide hole 12 for the sliding of the control rope. The traction device can be a winch 13.

[0029] In the natural state, the conical hole allows the fish that enter between the inner and outer nets to move only upwards, that is, the conical hole is equivalent to a one-way valve for the fish. In this way, even if the fish is not driven upwards by the middle brush body, the fish will automatically move upwards, so that the patrol personnel can find it in time.

[0030] The control rope is pulled upward to make the plates on the same spacer rotate synchronously, achieving a state of parallel fit with the spacer, which is equivalent to the conical hole being opened. At this time, the distance between the two relative plates is greater than the length of the middle brush body, so that the middle brush body can pass smoothly. After the middle brush body moves up and down once, that is, the middle brush body moves to the bottom of the mesh box, the electromagnet is powered off, and the inner brush body, the outer brush body and the middle brush body are disengaged from the attraction, so that the trolley can move to the next spacer to achieve control of the middle brush body.

[0031] A limiting body 14 is provided below the rotational connection between the plate body and the spacer, and the limiting body limits the plate body from further rotating downward so that a minimum distance can be provided between the two plate bodies.

[0032] The middle brush body of this embodiment can be a plate body, and bristles 201 are arranged on the two sides of the plate body corresponding to the inner and outer meshes, and guide rollers 202 are arranged on the two sides corresponding to the middle brush body to reduce friction. The middle of the middle brush body has a mesh 203 to reduce resistance.

[0033] Embodiment 2

[0034] like Figure 7 As shown, different from the above embodiment, it further includes an auxiliary boat 15, which is moved by pulling the trolley by a towing rope. The auxiliary boat is provided with a sewage suction pump 16, and the pipe mouth of the suction pipe 17 of the sewage suction pump is pulled up and down by the outer brush body, so as to absorb the cleaned dirt in real time, and collect or discharge it to a position far away from the net cage through the sewage suction pump.

[0035] Although some terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention. The execution order of actions, steps, etc. in the devices and methods shown in the specification and the drawings can be implemented in any order as long as there is no special explicit limitation on the order and the output of the previous processing is not used in the subsequent processing. The use of "first", "next", etc. for the convenience of description does not mean that it must be implemented in such an order.

[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
