[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] See also Figure 1-Figure 7, a fish-water separation type composite grid channel, comprising a channel unit 2, a transition bridge 5, a bracket 7, and a water guide plate 8; the channel unit 2 is in an elongated shape, with side baffles on both sides, and the bottom is divided into a guide section and a fish-water separation section; the guide section is watertight, and is provided with a plurality of partition plates 3, the spacing between each partition plate 3 is slightly larger than the width of the fish body, and the fish-water separation section is a grid structure; the transition bridge 5 is used to be arranged between adjacent channel units 2, and its two side surfaces and bottom surface are both folded plate-shaped, and the angle between adjacent channel units 2 can be adjusted; the bracket 7 serves as a supporting component of the fish-water separation type composite grid channel, and the height of each supporting foot is adjustable, which is used to adjust the inclination angle of the fish-water separation type composite grid channel, and then adjust the conveying speed; the water guide plate 8 is fixedly arranged below the fish-water separation section of the channel unit 2, and is used to receive the leaking water of the fish-water separation section and convey it forward.

[0024] In this embodiment, see Figure 1 , and also includes a baffle 1, which is shaped like the positive projection surface of the grid structure and can be sealed and covered on the grid structure so that the channel unit 2 does not separate fish and water; the baffle 1 is an accessory that corresponds one-to-one to the channel unit 2.

[0025] In this embodiment, the front end of the fish-water separation composite grid channel is connected to a fish suction pump and is only used for catching saury, which is not shown in the accompanying drawings.

[0026] In this embodiment, see Figure 5 and Figure 1 , and also includes a finisher, which is fixedly arranged at the front of the frontmost channel unit 2 and has an eight-shaped introduction port.

[0027] In this embodiment, see Figure 1 and Figure 2 The height of the partition plate 3 is slightly higher than the height of the saury.

[0028] The following is a detailed introduction to the specific structure and usage:

[0029] 1. When the fish school passes through the sorter ( Figure 5 ) When entering the channel, there is a partition on the sorter, which is used to dredge and buffer a large number of fish to prevent blockage in the back channel. The entrance of the sorter is open, which is convenient for docking with the fish suction pump to allow the fish to enter.

[0030] 2. When the fish water enters the channel, the channel is divided into several sections and each section is connected by a transition bridge 5 ( Figure 3 ) connection, the transition bridge uses elastic material to achieve flexible bending between each section of the channel, which can meet the space requirements on board.

[0031] 3. The bottom of the channel is composed of a grid structure 6. The fish flows out along the channel. During the process, the water is filtered by the grid structure 6 to the water guide plate 8 below, and flows to the correct place by the water guide plate 8. This can prevent the water from falling to the ground and making the ground too slippery and dangerous. The height of the water guide plate 8 from the channel can also be adjusted.

[0032] 4. There is a partition 3 in front of each channel to further dredge the fish. The baffles on both sides of the channel are made of thermoplastic rubber material, which can protect the fish and prevent the fish from colliding and wearing each other.

[0033] 5. The support 7 of the entire channel is also adjustable. Its height can be adjusted according to demand to control the speed of the fish passing through the channel.

[0034] 6. A baffle 1 is additionally designed on the fish-water separation section of the overall channel, such as Figure 1 As shown, its size is the same as the size of the orthographic projection surface of each grid segment. The purpose is to cover and protect the grid when the channel is not in use; when the objects to be transported do not need to be separated, it can be used as a physical channel to achieve more perfect functions.

[0035] 7. The width of the entire channel can be determined according to the yield of the fish school. Its length and number of sections can be determined according to the size of the fishing boat.

[0036] The biggest advantage of this equipment is that it combines the advantages of the fish-water separator and the channel, removes unnecessary parts, and combines the main functions of the two systems on the channel. It can alleviate the space requirements. In addition, the detailed processing of the channel can also meet the requirements of different working environments. The application range of the composite channel is wider; at the same time, the modular design of the fishing vessel transport channel and the fish-water separator can be flexibly assembled according to the length requirements, which enhances the versatility of product components and reduces costs; and the transition bridge can easily adjust the angle between adjacent channel units, which is convenient for flexible adjustment in a small space.

[0037] The above are preferred embodiments of the present invention. A person skilled in the art may make various changes or improvements on this basis. Without departing from the general concept of the present invention, these changes or improvements should fall within the scope of protection of the present invention.
