Embodiment

[0019] refer to Figure 1-2 , a sinking type shellfish ecological restoration device, including a box body 1 without a lower wall and a hollow sealing plate 2, the side wall of the box body 1 is made of metal mesh, and seawater can pass through the side of the box body The shellfish in the box body 1 can start to grow when it comes into contact with seawater. A hard pipe fitting 3 is sealed and fixed on one side of the sealing disk 2, and a piston plate 5 is sealed and slidably connected in the pipe fitting 3, and the piston plate 5 is close to the sealing disk. One end of 2 is fixed with a fixed plate 6, and two limit rods 7 are connected slidingly through the fixed plate 6, and the inner wall of the pipe fitting 3 close to the end of the sealing disc 2 is provided with two limit grooves, and the two limit rods 7 are close to each other One end of each is connected with a magnetic conduction block 9 through the rotating rod rotation, and a spring 8 is fixed on the end of the ...

Abstract

The invention discloses a sink-to-bottom type shellfish ecological remediation device. The sink-to-bottom type shellfish ecological remediation device comprises a tank without the lower wall and a hollow sealing plate and is characterized in that the lateral wall of the tank is prepared from a metal net, a hard pipe is fixed to one side of the sealing plate in a sealing manner, a piston plate is slidably connected into the pipe in a sealing manner, a fixing plate is fixed at one end, close to the sealing plate, of the piston plate, two limit rods are slidably connected to the fixing plate in apenetrating manner, the inner wall of one end, close to the sealing plate, of the pipe is provided with two limit grooves, and a magnetic block is rotatably connected to each of one ends, close to each other, of the two limit rods through a rotary rod. The sink-to-bottom type shellfish ecological remediation device has the advantages that a decomposable support plate can be slowly decomposed in seawater after the tank is put into seawater, and shellfish located on the decomposable support plate falls from the tank to contact with the seabed; the tank can still limit the shellfish after the shellfish falls to the seabed, so that the shellfish can be prevented from being washed by seawater to the seabed where the shellfish is difficult to grow.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a bottom-sinking shellfish ecological restoration device. Background technique [0002] Among marine organisms, shellfish have good filtration and enrichment characteristics, can absorb and consume various toxic substances such as benzene and phenol, consume excess organic matter in seawater, and play a role in purifying seawater; shellfish are well-known ecological cleaners, can Filter out the sediment in the water, improve the water quality, and make the water clearer. What's more, they can remove toxic substances from water. [0003] Artificial shellfish ecological restoration means that shellfish are released into natural marine waters where shellfish resources have declined after artificial breeding and breeding, so that the natural population of shellfish can be restored. The existing technology of artificial shellfish ecological restoration is to pack the ...
