Embodiment 1

[0025] like figure 1 , figure 2 , image 3 As shown, the artificial fish reef that can automatically cast bait includes a reef body 1 and a cuboid bait container 2. The bait container 2 floats on the sea surface. The bottom of the bait container 2 is provided with a delivery pipe 3. 3 is provided with tidal power automatic baiting device, and reef body 1 is provided with dragline 4, and dragline 4 enters in the bait container 2 through the bottom of bait container 2. The tidal power automatic bait throwing device comprises a bait flipping pallet 5, a pallet driving lever 6, a cable shaft 7, a coil reed 8 and a lever paddle 9, and the bait flipping pallet 5 is hinged on the inner wall of the bait container 2 . The bait container 2 inwalls are provided with a lever support, and the supporting plate driving lever 6 is hinged on the lever support. The bottom of the bait container 2 is funnel-shaped, and the delivery pipe 3 is connected to the lowest point of the funnel. The ...

Embodiment 2

[0028] like Figure 4As shown, the tidal power automatic baiting device includes a conical contact pressure block 20, a movable baffle 22 and a baffle drive lever 23, a rigid guide rod 19 is fixed on the reef body 1, and the bait container 2 is slidably sleeved on the On the guide rod 19, the conical contact pressure block 20 is fixed on the guide rod 19, and the conical contact pressure block 20 is arranged on the highest position that the bait container 2 can reach, and the highest position needs to be determined according to the long-term tide water level record. The bottom of the bait container 2 is provided with a funnel-shaped discharge structure, and the conveying pipe 3 is connected with the bait container 2 at the lowest point of the funnel-shaped discharge structure, and the bottom of the bait container 2 is a cuboid. The center of the bait container 2 is provided with a guide rod sleeve 27, the guide rod sleeve 27 starts from the bottom of the bait container 2, and ...

Abstract

The invention provides an artificial fish reef capable of improving ecological carrying capacity. The artificial fish reef comprises a reef body and a bait container. The bait container floats on a sea surface; the bottom of the bait container is provided with a conveying pipe; a tide power automatic bait casting device is arranged between the bait container and the conveying pipe; an automatic bait supplementing device in linkage with the tide power automatic bait casting device is arranged in the bait container. The reef body is provided with an optical fiber and branch-shaped alga planting frames. One end of the optical fiber is provided with a light collector and the other end is provided with emitters, wherein the light collector is exposed on the sea surface and the emitters are fixed above the alga planting frames. According to the invention, the food supply of artificial fish reef areas is reinforced; more chances for rehabilitation are provided for the ecological systems of the artificial fish reef areas; the optical fiber can guide natural light above the sea surface to the fish reef areas located relatively deep underwater, so that the fish reef areas enjoy excellent light conditions, algae and microorganisms in the fish reef areas can perform photosynthesis rapidly and continuously and abundant food is provided for marine animals such as fishes.

Description

technical field [0001] The invention relates to a marine aquaculture facility, more specifically, it relates to an artificial fish reef which can improve the ecological carrying capacity. Background technique [0002] With the continuous improvement of living standards, people's consumption demand for seafood is increasing. However, the traditional way of fishing at sea is difficult to produce a catch increase that can meet people's needs. Therefore, fishery practitioners have to over-excavate by means of exhausting fish Fishery resources in the middle and near seas may take greater risks to go deep into the far sea, causing serious damage to the marine ecology and greatly increasing the cost of fishery production. Putting artificial fish reefs can provide a feasible way to solve the above problems. Artificial fish reefs can improve the ecology of the sea area, create a good environment for marine organisms to inhabit, and provide fish with the resources to gather, reproduce...
