Based on the above embodiments, the technical problem to be solved by the present application is how to further improve the sample accuracy. For this reason, this application has realized through second mounting bracket 1a and gravity sensor 1b whether vertical decurrent function of monitoring devices tail end. The gravity sensor 1b is electrically connected with the controller; after an operator stretches the device into water, the vertical condition of the tail end of the device is sensed constantly through the gravity sensor 1b, once the device is influenced by external force to displace, the tail end is not downward vertically any more, then the gravity sensor 1b feeds back a signal to the controller, and the controller timely reminds the operator after receiving the signal, so that sampling is stopped temporarily. Thereby further improving the accuracy of the sample.
Further, the rotation driving assembly 3f provided by the present application still has the defects that when the operator shakes the rocking handle 3f2, the other hand needs to firmly hold the frame 1, the body force is limited, the disturbance of the water body is too large in the sampling process, so that the dissolved greenhouse gas is dissipated, and the accuracy of the sample is affected, and in order to solve the problem, as shown in fig. 2:
The frame 1 comprises a grip 1c, and the grip 1c is fixedly arranged on the frame 1.
Based on the above embodiments, the technical problem that the present application intends to solve is how to further improve the portability of the device. Therefore, the grip 1c of the present application realizes a function convenient for an operator to grasp. When the operator shakes the rocking handle 3f2, the other hand grasps the handle 1c, so that the operator can use the device more labor-saving, the sampling stability is further improved, and the disturbance to the water body is reduced, thereby causing the dissipation of dissolved greenhouse gases.
Further, the piston 2b provided by the present application still has the defect that the greenhouse gases in the sample can escape from the joint between the piston 2b and the sampling bottle 2a, and in order to solve the problem, as shown in fig. 4 to 5:
Based on the above embodiments, the technical problem that the present application intends to solve is how to further reduce the emission of greenhouse gases. For this reason, this application has realized improving the function of sampling bottle 2a leakproofness through sealing washer 2 d. The sealing performance of the matching part of the sampling bottle 2a and the piston 2b is improved through the sealing ring 2d, so that the gas loss is further reduced, and the sample accuracy is improved.
The above examples only show one or more embodiments of the present invention, and the description is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
