[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The present invention provides an embodiment of a greenhouse gas emission monitor sampling tube, comprising:

[0023] A monitoring body 2, the sampling bottom end of the monitoring body 2 is connected to a sampling rod 3;

[0024] The support assembly 4 includes a positioning sleeve 41, which is sleeved on the outside of the monitoring body 2, and a support shaft 42 is hinged at the bottom of the positioning sleeve 41. A support tube 43 is sleeved on the outside of the support shaft 42, and a guide shaft 48 is connected to the bottom center of the support tube 43. A positioning ring 44 is sleeved on the outside of the guide shaft 48 and the support tube 43, and an abutment rod 45 is hinged on the lower surface of the positioning ring 44. Through the setting of this structure, the height adjustment of the support tube 43 and the support shaft 42 can be achieved under the telescopic adjustment of the support tube 43 and the support shaft 42, so as to flexibly provide auxiliary support for the sampling rod 3 and ensure the stability of the sampling rod 3 after installation. There are at least three groups of abutment rods 45 distributed around the circumference to ensure the stability of the support after deployment.

[0025] Furthermore, the monitoring body 2 is mounted on the top of the tripod support 1 , and the height of the tripod support 1 is flexibly adjustable.

[0026] Furthermore, the top of the support assembly 4 is open, and the support ears at the opening are penetrated by fastening bolts, the support tube 43 and the support shaft 42 are connected in a limited sliding manner, and a limited baffle is provided at the positioning sleeve 41 corresponding to the support shaft 42 to ensure that the support shaft 42 cannot rotate in the vertical state so that the rotation angle of the support shaft 42 is maintained at ninety degrees.

[0027] Furthermore, a threaded hole is opened on the outside of the support tube 43, and the internal thread of the threaded hole is connected with a bolt, and the bolt abuts against the outer wall of the support shaft 42. Through the penetrating connection of the bolt, the support shaft 42 can be abutted and limited, thereby improving the stability of the support shaft 42 and the support tube 43 after height adjustment.

[0028] Furthermore, a threaded hole is also provided on the positioning ring 44, and the internal thread of the threaded hole is connected to a threaded rod, and the threaded rod abuts against the outer wall of the guide shaft 48. The positioning ring 44 is composed of two inner and outer rings, and the two rings are connected in an integral manner. Through the mutual cooperation between the positioning ring 44 and the threaded rod, after the positioning ring 44 is adjusted, the abutment adjustment of the threaded rod can be used to achieve extrusion of the guide shaft 48, thereby further improving the stability of the positioning ring 44 after adjustment.

[0029] Furthermore, a guide groove for the sliding of the positioning ring 44 is provided on the support tube 43, and the inner wall of the guide groove is fixedly connected to the limiting rod 49. The bottom of the support tube 43 is a concave structure, and a through groove is provided on the outer wall of the concave structure. The opening of the through groove facilitates the rotation of the abutment rod 45, and the hidden storage of the abutment rod 45 greatly improves the convenience of its storage.

When the guide ring 47 is in the lowest state, the hinge axes at both ends of the hinged rod 46 are on the same horizontal line. Through the mutual cooperation between the hinged rod 46 and the guide ring 47, they can be expanded to increase the support area of the bottom of the support assembly 4, thereby improving its support stability.

[0031] Working principle: The tripod bracket 1, monitoring body 2 and sampling rod 3 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When using the present invention, the device is first assembled and positioned, and then the support shaft 42 is rotated so that the support shaft 42 and the sampling rod 3 are vertically distributed. The abutment rod 45 at the bottom of the support tube 43 is further opened, and the positioning ring 44 is squeezed and positioned. Then, according to the installation height of the sampling rod 3, the position of the support tube 43 is adjusted so that the bottom of the abutment rod 45 is in contact with the ground, thereby completing the stable support of the sampling rod 3.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
