DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figure 1 — Figure 3 As shown, the present invention provides: a wetland carbon flux measuring device, including a detection cover 1 and a supporting assembly 2, wherein the supporting assembly 2 has a plurality of supporting assemblies and is circumferentially distributed on the outer peripheral wall of the detection cover 1; the supporting assembly 2 includes a flip assembly 21 and a supporting assembly 22, wherein the flip assembly 21 includes a mounting seat 211, a rotating slide 212, a connecting rod 213 and a positioning pin 214; the mounting seat 211 is arranged on the outer peripheral wall of the detection cover 1; the rotating slide 212 is arranged on the mounting seat 211 At the top, the tail end of the rotating slide 212 is rotatably connected to the mounting seat 211, and the head end of the rotating slide 212 is away from the detection cover 1; the tail end of the connecting rod 213 passes through from the head end of the rotating slide 212 to the tail end of the rotating slide 212, the connecting rod 213 is slidably connected to the rotating slide 212, and the head end of the connecting rod 213 is connected to the support assembly 22; the positioning pins 214 are respectively arranged on both sides of the mounting seat 211, and the positioning pins 214 pass through the mounting seat 211 and are inserted into the rotating slide 212.

The outer wall of the detection cover 1 is circumferentially distributed with a plurality of supporting components 2, so that the detection cover 1 is provided with a multi-directional support force through the plurality of supporting components 2, so as to ensure that the detection cover 1 can be stably placed on the wetland. The tail end of the connecting rod 213 is connected by rotating the sliding seat 212 and the mounting seat 211 arranged on the outer wall of the detection cover 1. The head end of the connecting rod 213 is connected to the supporting assembly 22, so that when the detection cover 1 is placed on the wetland, the supporting assembly 22 can provide supporting force to the detection cover 1 through the connecting rod 213, so as to prevent the detection cover 1 from tilting on the wetland; because when the carbon flux is detected in the wetland, it is necessary to detect multiple places in the wetland to ensure the accuracy of the final data, so it is necessary to move the measuring device to the next detection point, but the supporting assembly 2 outside the detection cover 1 is in an unfolded state, which makes it difficult for the staff to take the measuring device, so a rotating slide 21 is set on the mounting seat 211 2, and at the same time, the tail end of the connecting rod 213 passes through the rotating slide 212 and is slidably connected with the rotating slide 212, so that when the detection cover 1 needs to be transferred, the connecting rod 213 and the support assembly 22 can be rotated upward together by the rotating slide 212 until the connecting rod 213 is rotated to a vertical state, and then due to the sliding connection between the connecting rod 213 and the rotating slide 212, the tail end of the connecting rod 213 can slide downward and pass through the mounting seat 211 until the support assembly 22 and the top of the mounting seat 211 abut against each other.

In this way, when the connecting rod 213 slides upward in the vertical direction and the tail end of the connecting rod 213 is inside the rotating slide 212, the first sliding block 2121 and the inner side wall of the first sliding groove 2131 abut against each other, thereby limiting the connecting rod 213 from sliding upward further, and then The connecting rod 213 can be rotated downward, and the rotating slide 212 can be fixed to the mounting seat 211 by the positioning pin 214. At the same time, the connecting rod 213 and the rotating slide 212 are connected by the first slide groove 2131 and the first slider 2121, so as to limit the upward and downward movement of the connecting rod 213 in a horizontal state. When the connecting rod 213 is in a horizontal state, the tail end of the connecting rod 213 abuts against the mounting seat 211, so as to limit the movement of the connecting rod 213 in the horizontal direction, so that when the supporting assembly 22 is supporting, the connecting rod 213 will not be displaced.
