The invention relates to the technical field of gas collection devices, in particular to a greenhouse gas collection device suitable for variable-water-level wetlands of lakes and rivers, the greenhouse gas collection device comprises an underwater walking part, the underwater walking part is connected with a gas collection part, and a self-adaptive adjusting part is arranged between the underwater walking part and the gas collection part; the self-adaptive adjusting part comprises a shaft seat fixedly connected to the top end of the underwater walking part, one side of the shaft seat is rotationally connected with a horizontally-arranged short rod, one end of a clockwork spring is fixedly connected to the outer side wall of the short rod, the other end of the clockwork spring is fixedly connected to the inner side wall of a rotating ring, and the rotating ring is arranged on the outer side of the short rod in a sleeving mode. One end of a first connecting line is fixedly connected to the outer side wall of the rotating ring, the first connecting line is wound on the outer side wall of the rotating ring, the other end of the first connecting line is fixedly connected with the gas collecting part, and a braking mechanism is arranged at the end, away from the shaft seat, of the short rod. According to the invention, the position of the floating plate relative to the water surface is not greatly changed when the water surface is changed.
本发明涉及气体采集装置技术领域,特别是涉及一种适用于湖泊、河流可变水位湿地的温室气体采集装置,包括水中行走部,水中行走部连接有气体采集部,水中行走部与气体采集部之间设置有自适应调节部;自适应调节部包括固接在水中行走部顶端的轴座,轴座的一侧转动连接有水平设置的短杆,短杆的外侧壁上固接有发条弹簧的一端,发条弹簧的另一端固接在转动环的内侧壁上,转动环套设在短杆的外侧,转动环的外侧壁上固接有第一连接线的一端,第一连接线绕设在转动环的外侧壁上,第一连接线的另一端与气体采集部固接,短杆远离轴座的一端设置有制动机构。本发明可以保证在水面发生变化时浮板相对于水面的位置不会发生太大的变化。
