The upper edge and the lower edge of the brush plate are inclined towards the direction far away from the netting, so that the device cannot be hung and hooked on the netting in the process of adjusting the upper position and the lower position, and the good contact between the device and the netting is realized.
The "outer side" of the corner brush plate 5 and the straight brush plate 7 refers to the convex side of the corner brush plate 5 and the straight brush plate 7, and the corresponding "inner side" refers to the concave side of the corner brush plate 5 and the straight brush plate 7. The concave sides of the corner brush plate 5 and the straight brush plate 7 are in contact with the outer side of the fixed frame, and the corner brush plate 5 and the straight brush plate 7 are fixed and connected with the fixed frame through bolts and hanging plate accessories, as shown in fig. 6.
The fixed frame is a square frame formed by assembling an upper square structure and a lower square structure which are the same and are formed by assembling four plastic pipes 1 based on an oblique connecting piece 3 and a corner connecting piece 4 through a plurality of vertical connecting pieces 2, and the number of the oblique connecting pieces 3 at the four corners is not less than two, as shown in figure 1. The middle space of the fixed frame is large, the operation in the net cage is not influenced, and the frame is made of cheap materials and has economical efficiency and practicability.
The details of the mutual connection between the vertical connecting piece 2, the oblique connecting piece 3, the corner connecting piece 4 and the plastic pipe 1 are shown in fig. 2 and 3. The diagonal connectors 3 form a triangular stable shape at the four corners of the fixed frame. The whole fixed frame has enough strength and rigidity, and does not deform or buckle under the action of sea wave load.
The middle part of the corner brush plate 5 is arc-shaped, the radian of the arc-shaped brush plate is the same as that of the corner connecting piece 4, and the inner side of the corner brush plate 5 can be just matched and arranged on the outer side of each corner of the fixed frame. The corner brush boards 5 are arranged at the outer sides of four corners of the fixed frame, the straight brush boards 7 are arranged between the adjacent corner brush boards 5 at the outer sides of all the sides of the fixed frame, and after the corner brush boards 5 and the straight brush boards 7 are arranged, the brush hairs 6 on the corner brush boards 5 and the straight brush boards 7 are distributed continuously at the outer sides of the periphery of the frame, as shown in fig. 6.
The corner brush plate 5 and the straight brush plate 7 are arranged on the outer sides of the periphery of the fixed frame based on bolts and hanging plate accessories, the outer contour size of the fixed frame, which does not contain the brush hair 6 after the corner brush plate 5 and the straight brush plate 7 are assembled, is slightly smaller than the cross section size of the netting 10, the vertical heights of the corner brush plate 5 and the straight brush plate 7 are equal, and the value range is 0.5 m-1.5 m.

A proper amount of fine sand can be filled in the plastic pipe 1 of the fixed frame, so that the total density of the automatic cleaning net cage device is greater than that of seawater, and the device can sink in seawater. The method for adding sand into the plastic pipe is adopted, the whole weight of the structure is increased, and the method is simple, feasible, low in cost and practical.
The device is installed in the interior of the net cage, as shown in fig. 9. The partial schematic view of the connection between the device and the net cage is shown in fig. 10 and 11. The device is convenient to install and remove, can fix and hold the netting to a certain degree, and ensures that the netting is difficult to gather and draw close with each other under the action of ocean currents, thereby being beneficial to maintaining the volume ratio of the netting.
The principle of the proposed device for automatically cleaning the netting 10 is as follows: the netting 10 swings and rocks under the action of wind waves and ocean currents, and inevitably contacts with an automatic cleaning net cage device arranged in the net cage, the brush hairs 6 around the device are irregularly scraped and physically contacted with the netting 10, the brush hairs 6 continuously scrape and brush marine fouling organisms parasitizing on the netting, so that the marine fouling organisms are difficult to attach to the netting, and the marine fouling organisms fall off and are separated from the netting through the scraping and brushing action for a certain time, so that the automatic cleaning effect on the netting is achieved; the device can clean the netting 10 in the vertical height range of the straight brush plate 7 at one time, after a certain time interval, the device is moved up or down by adjusting the length of the lifting rope 8, the subsequent new netting position is automatically cleaned, the position is periodically and circularly changed, and the automatic cleaning in the depth universe range of the netting 10 is gradually realized.
Therefore, the device provided by the technology should periodically change the position to realize the automatic cleaning of the whole area within the depth range of the netting 10. The lifting rope 8 is provided with size scales, so that the upward movement or downward movement distance of the device can be accurately controlled, and the upward movement or downward movement distance each time is slightly smaller than the vertical height of the straight brush plate, so that the depth range of the netting can be gradually cleaned, and the position is not easy to be missed.
As for the time interval of the periodic position change of the device, the time interval is comprehensively determined according to the fouling organism species and the ocean current speed of the culture sea area. If the time interval is too short, the position of the brush hair is changed without causing substantial influence on fouling organisms on the netting, so that the automatic cleaning effect is poor, and the attachment and growth of marine fouling organisms cannot be effectively restrained and controlled; if the time interval is too long, the bristles can automatically clean the fouling organisms on the net completely, but the time for completely cleaning the net once in the whole depth range is too long, so that the net cleaning work and the culture cycle are staggered and inconsistent, and the operation is unreasonable. Therefore, the time interval of the replacement position needs to be reasonably determined, so that on one hand, marine fouling organisms cannot be attached to and grow on the net, and on the other hand, the time period for cleaning the net once is suitable for the requirement of mariculture.
According to the provided idea, an automatic cleaning net cage device matched with the circular frame net cage can be manufactured to realize automatic cleaning of the circular net cage, which belongs to equivalent modification and change of the technology and is not repeated herein.
