Anti-blocking artificial fish reef and using method thereof

Abstract

The invention discloses an anti-blocking artificial fish reef and a using method thereof. The anti-blocking artificial fish reef comprises a fish reef seat, a fish reef cover, a floating plate, a vertical plate and a first transmission mechanism, wherein the interior of the fish reef seat is of a hollow structure; the fish reef cover is rotatably arranged on the upper part of the fish reef seat; the floating plate is directly or indirectly arranged on the sidewall of the fish reel cover; the vertical plate capable of sliding vertically is arranged in a vertical hole in the bottom of the fish reel seat; the first transmission mechanism is connected to the fish reel cover and the vertical plate and can convert the rotation of the fish reef cover into the vertical movement of the vertical plate; a residue discharge hole is formed in the vertical plate; and the sidewall of the vertical hole is provided with a resetting mechanism used for limiting and resetting the vertical plate. Accordingto the anti-blocking artificial fish reef and the using method thereof, the first transmission mechanism can convert the rotation of the fish reef cover into the vertical movement of the vertical plate, so that residues such as fish excrement and sludge deposited on the vertical plate are shaken; and the residue discharge hole on the vertical plate can efficiently discharge the residues out of the fish reef seat, so that the structure is ingenious.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an anti-clogging artificial fish reef and a using method thereof. Background technique [0002] Artificial reefs are a type of artificial setup used to provide shelter to fish during marine aquaculture. Artificial reefs usually include an area used for fish and other aquatic animals. Since the excrement of fish and other aquatic animals often contains residues such as small particles of sand and food residues, it is very easy to cause sedimentation of residues in areas used to provide shelter for fish in artificial reefs, as well as seawater in fish protection areas. The flow is easily blocked, which will cause the water quality in the fish protection area to be poorer than that of the surrounding sea area. The content of ammonia nitrogen and nitrous nitrogen is high, and the dissolved oxygen content is low, which is not conducive to the survival and aggregation of fish and ...

Problems solved by technology

Since the excrement of fish and other aquatic animals often contains residues such as small particles of sand and food residues, it is very easy to cause sedimentation of residues in areas used to provide shelter for fish in artificial reefs, as well as seawater in fish protection areas. The flow is easily blocked, which will cause the water quality in the fish protection area to be poorer than that of the surrounding sea area. The content of ammonia nitrogen and nitrous nitrogen is high, and the dissolved oxygen content is low, which is not conducive to the survival and aggregation of fish and other aquatic animals, and it is easy to affect fish protection. Regional biome structure

In addition, the sedimentation of residues and the reduction of the volume of the fish protection area are likely to reduce the functional effect of the artificial reef. In the prior art, there is a problem that the fish protection area in the artificial fish reef is easy to deposit residues. After searching, the application publication number An anti-clogging artificial fish reef disclosed by CN108633805A includes a settlement seat, a support group, a fish reef bottom, a fish reef cover and a floating box, the fish reef bottom is located above the settlement seat, and the support group includes At least one support, the upper end of the support is connected to the bottom of the fish reef, the lower end of the support is connected to the settlement seat, the bottom of the fish reef includes a bottom fish protection cavity, and the bottom fish protection cavity is the upper end Open hemispherical, the bottom of the fish reef is provided with a slag discharge hole at the lower end of the bottom fish protection chamber, the upper end of the slag discharge hole communicates with the bottom fish protection chamber, and the lower end of the slag discharge hole runs through The lower end of the bottom of the fish reef can ensure the clean water quality in the area that provides shelter for fish, but its effect on the treatment of sludge residues is average, and it cannot completely solve the sludge residues. Therefore, we propose an anti-clogging type Artificial reefs are used to solve the above problems
