The utility model provides an ups and downs formula ke shed structure, includes rack, container, gasbag and gaseous adjusting device. The container includes the body, and the body is located the rackand is enclosed the structure cavity. The gasbag is located in the cavity. Gaseous adjusting device includes air pump and trachea, and the trachea is connected between air pump and gasbag, and the logical air through tube of air pump sends into the inside and logical air through tube of gasbag with the inside gaseous past outer discharge of gasbag with the extraneous gas to make the gasbag switchover between expanded state and contraction state. When the gasbag was in expanded state, the rack emersion was on the sea. When the gasbag was in the contraction state, the rack immerse under the sea. Borrow this, the gasbag can receive the appropriate protection of container, is difficult for being punctureed by the foreign matter, can maintain the effect of the ups and downs of rack in the sea.一種沉浮式蚵棚結構，包括棚架、容器、氣囊及氣體調節裝置。容器包括本體，本體設於棚架且圍構腔室。氣囊設於腔室中。氣體調節裝置包括氣泵及氣管，氣管連接於氣泵與氣囊之間，氣泵藉由氣管將外部氣體送入氣囊內部以及藉由氣管將氣囊內部的氣體往外排出，以使氣囊切換於膨脹狀態與收縮狀態之間。當氣囊處於膨脹狀態時，棚架浮出於海面之上。當氣囊處於收縮狀態時，棚架沉入於海面之下。藉此，氣囊可受到容器妥善的保護，不易被異物刺破，得以維持棚架的沉浮於海面的效果。
