The middle part of the upper end face of the support assembly 1 is fixedly connected with a conveying pump 6, the output end and the input end of the conveying pump 6 are both fixedly connected with support pipes 7 penetrating through, and the inner walls of the two support pipes 7 are both connected with filters 9 penetrating through; the connecting frame 3 is connected with two support plates 4 distributed along the axial direction of the support pipe 7 penetrating through, the ends of the two support plates 4 extending into the protective space are both fixedly connected with protective clamping frames 5, the protective clamping frames 5 are U-shaped and the open ends thereof face the support pipe 7, and the support pipe 7 and the filter 9 are covered in the protective clamping frames 5.

[0040] The support assembly 1 comprises a support plate 11, the four corners of the support plate 11 are all fixedly connected with support rods 12 perpendicularly, and the protective frames 2 are provided with two through holes for the two support rods 12 on the same side to penetrate through. The upper end faces of the two axial ends of the support plate 11 are both provided with two positioning clamping grooves 13, the two positioning clamping grooves 13 on the same end form a group, and the open end of one protective clamping frame 5 is inserted into the group. The middle part of the upper end of the support plate 11 is provided with a connecting groove 14 matched with the plug-in of the conveying pump 6, and the connecting groove 14 is located between the two groups of two positioning clamping grooves 13. The conveying pump 6 is fixedly connected with the support plate 11 in the connecting groove 14.

[0041] Therefore, the conveying pump 6 can be supported by the support assembly 1, the conveying pump 6 is connected with the connecting groove 14 on the support plate 11 penetratingly and is fixed by a screw, so as to fix the position of the conveying pump 6; the two protective frames 2 are sleeved with the two groups of two support rods 12 transversely and are fixed by a screw, so as to connect the two protective frames 2 with the support assembly 1 together; the connecting frame 3 is sleeved with the two protective frames 2, and the use process of the conveying pump 6 is protected by the connecting frame 3 and the two protective frames 2 together, so as to avoid the conveying pump 6 from being damaged due to collision. The support pipe 7 and the filter 9 are protected by the two protective clamping frames 5, so as to avoid the filter 9 from falling off due to collision with external natural gas pipelines.

[0042] Further, with reference to Figure 2 andFigure 4 The outer surface of each of the two support pipes 7 is coaxially fixed with a fixed pipe 8, and the opposite end of each of the two fixed pipes 8 is provided with an annular clamping slot 10, and the inner wall of each of the two annular clamping slots 10 is connected with a connecting assembly 15. The connecting assembly 15 comprises a connecting pipe 151, and the outer surface of the connecting pipe 151 is coaxially fixedly connected with a first fixing ring 153 and a second fixing ring 156 at two ends, respectively.
