The seaweed attachment base is made of concrete. The artificial transplanted seaweed is attached to one side surface of the seaweed attachment base facing the center of the hemispherical algal reef frame.
As shown in fig. 1 and 3, the tide level self-lifting adjusting mechanism comprises a main cylinder 3.1 with an axis extending up and down, a main piston body 3.7 arranged in the main cylinder, an adjusting cylinder 3.2 with an axis extending up and down, and an adjusting piston 3.3 arranged in the adjusting cylinder. The inner diameter of the main cylinder is larger than that of the adjusting cylinder, and in this embodiment, the inner diameter of the main cylinder is larger than 3 times of that of the adjusting cylinder.
The main cylinder body is fixed on the settlement counter weight and is connected with the settlement counter weight through a connecting piece. The upper end of the main cylinder body is opened, the lower end of the main cylinder body is closed, and the lower end face of the main cylinder body is provided with a main cylinder body connecting port communicated with the inner cavity of the main cylinder body. An upper limit block 3.8 is arranged on the inner side surface of the main cylinder body and above the main piston body. The inner side surface of the main cylinder body is also provided with a lower limiting block 3.5, and the main piston body is positioned above the lower limiting block. A pre-tightening compression spring 3.6 is arranged in the main cylinder body and between the lower end of the main cylinder body and the main piston body. When the main piston body is abutted against the upper limiting block, the adjusting piston is close to the lower end of the adjusting cylinder body.
The adjusting cylinder body is fixed on the settlement counterweight and is connected with the settlement counterweight through a connecting piece. The upper end of the adjusting cylinder body is open, the lower end of the adjusting cylinder body is closed, and the lower end face of the adjusting cylinder body is provided with an adjusting cylinder body connecting port communicated with the inner cavity of the adjusting cylinder body.

as shown in fig. 1, the sedimentation weight sinks to the seabed, and the algal reef body connecting rope is connected with the sedimentation weight and suspended in the water. The main piston body is propped against the lower limiting block under the action of the pre-tightening compression spring. The settlement weight is kept at a set distance, for example 20 meters, from the surface.
Because the distance between the algal reef body and the sea surface can be adjusted through the connecting rope, the requirement on sea water transparency is not high, the suspended algal reef body cannot be covered by sediments, wide-area transplantation can be realized, and the algal field restoration area is enlarged. Meanwhile, the settlement counter weight and the algal reef body are both positioned under the water surface, so that the influence of sea surface storms can be avoided. The algal reef body forms an algal forest at the upper part and has the functions of cultivating the young and improving the water environment.
As shown in fig. 1 and 3, during the sea water rising process, the seabed water pressure gradually increases along with the rise of the sea level, and since the inner diameter of the main cylinder is greater than 2.5 times of the inner diameter of the adjusting cylinder, when the sea level rises to a certain height (for example, 1.5 m), the seabed water pressure overcomes the elastic force of the pre-tightening compression spring, so that the main piston body moves downwards until the elastic force of the pre-tightening compression spring reaches balance again, during the process, the adjusting piston moves upwards, and the upward moving distance of the adjusting piston is far greater than the downward moving distance of the main piston body, so that the algal reef body floats along with the sea level under the action of buoyancy, the distance between the algal reef body and the sea surface is maintained within a set range, and the algae can obtain a proper illumination condition.
When the sea water falls into the tide, the water pressure of the sea bottom is gradually reduced along with the reduction of the tide level, the main piston body is gradually reset (moves upwards) under the action of the elastic force of the pre-tightening compression spring until the elastic force of the pre-tightening compression spring is balanced again, the adjusting piston moves downwards in the process, and the moving distance of the adjusting piston is far greater than the moving distance of the main piston body, so that the algal reef body is pulled downwards (descends along with the tide level) under the action of the connecting rope, the distance between the algal reef body and the sea surface is maintained in a set range, and the seaweed obtains a proper illumination condition.
The algal reef body of this embodiment can realize going up and down along with the lift of tide level, makes the distance between algal reef body and the sea maintain at the within range of settlement to the marine alga that grows on the messenger algal reef body obtains suitable illumination condition.
