Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 In the shown embodiment, a shallow sea environment improvement device includes a buoy 1, a support frame 3 and a counterweight 4, and the three are connected by a stay rope, wherein the support frame 3 is as figure 2 As shown, it includes a central rod 302, a sliding sleeve 303 and several fan-shaped support plates 305. The central rod 302 is vertically arranged, and the sliding sleeve 303 can slide up and down along the central rod 302. The bottom of the central rod 302 is provided with a connecting seat 306, and the fan-shaped support The plate 305 is arranged on the connecting seat 306 around the central rod 302 in a circumferential direction, and can rotate relative to the connecting seat 306 on a vertical plane. The fan-shaped support plate 305 is provided with some seaweed cultivation bricks 7, the seaweed cultiv...

Abstract

The invention discloses a shallow sea environment improving device. The shallow sea environment improving device comprises a float, a supporting frame and a balancing weight which are connected through a pull rope sequentially. The supporting frame comprises a center rod, a sliding sleeve and a plurality of fan-shaped supporting plates, wherein the sliding sleeve is connected with the center rod in a sliding mode and the fan-shaped supporting plates are arranged in the circumferential direction of the center rod. A plurality of alga culture bricks are arranged on the fan-shaped supporting plates, a connecting base is arranged at the bottom of the center rod, the fan-shaped supporting plates and the connecting base are in rotary connection on a vertical face, a supporting rod is hinged between the sliding sleeve and the upper surface of each fan-shaped supporting plate, the sliding sleeve and the connecting base are connected through a tension spring, corresponding side edges of the adjacent fan-shaped supporting plates are attached tightly when the sliding sleeve is located at the dead center of the sliding stroke, and a deflation valve is arranged on the float. The shallow sea environment improving device has the advantages that alga seedlings can adhere to the shallow sea environment improving device to grow conveniently, the alga seedlings at the early growth stage can be better protected, the survival rate of alga is increased, and meanwhile concentrated input and management are convenient.

Description

technical field [0001] The invention relates to the field of marine algae cultivation, in particular to a shallow sea environment improvement device. Background technique [0002] Macroalgae grow in the intertidal subtidal zone and subtidal shallow water zone of the mid- and high-latitude seas. As supporting plants, other plankton, swimming animals, benthic animals, and environmental factors that coexist with them constitute the nearshore ecosystem. . Seaweed farms supported by macroalgae have high primary productivity, and at the same time form a complex animal and plant food web that can enrich eutrophic salts such as N and P, restrain the outbreak of "red tide" and protect the marine environment. The economic value created by seaweed farms is great. Seaweed itself has industrial, edible and medical value. Seaweed farms also provide places for fish to seek bait, avoid enemies, and lay eggs. However, according to recent observations, seaweed fields are disappearing, and s...
