In this embodiment: first, a pair of embedded probes 210 shown in fig. 1 is taken as an example, and more sets of embedded probes 210 may be provided in actual production to improve the accuracy of gas flow measurement. And the reflection type installation method shown in fig. 1 is selected, namely, sound waves emitted by two embedded probes 210 are mutually received in a V shape by being reflected by the pipe wall.
In the installation, the two first installation seats 321 are firstly attached to the same horizontal line of the gas pipeline 100, and then the two first installation seats 321 are pulled in the direction away from each other, in the process, according to the diameter of the gas pipeline 100, the first strapping 323 is automatically controlled to slide backwards along the direction shown in fig. 1 in the installation groove 324 by the first adjusting component 325 until the first strapping 323 is strapped on the surface of the gas pipeline 100, so that the first installation seat 321 is fixed on the gas pipeline 100.
Meanwhile, according to the fact that the specific sliding distance in the mounting groove 324 where the first strapping 323 is located is related to the pipe diameter of the gas pipeline 100, the distance between the two embedded probes 210 is automatically controlled to be consistent with the pipe diameter of the gas pipeline 100, when the pipe diameter of the gas pipeline 100 is smaller, the distance between the two embedded probes 210 is larger, so that the propagation distance of sound waves in a medium is increased, and measurement accuracy is improved.

In this embodiment: when the first mounting seat 321 is mounted on the gas pipeline 100, after the first strapping 323 is inserted from the mounting groove 324 by bypassing the gas pipeline 100, each tooth of the first strapping 323 can be meshed with each tooth groove 3253 on the first strapping 323 one by one through the rotation of the poking tooth 3252, and the first strapping 323 is pushed to move towards the rear side direction shown in fig. 1.
The embedded probe 210 is first mounted in the second mounting cylinder 3223, specifically may be slidably mounted or detachably mounted, and the second mounting cylinder 3223 is not directly mounted on the first mounting cylinder 3222, so that on one hand, the load of the first mounting cylinder 3222 when moving and positioning along with the first mounting seat 321 is reduced.
On the other hand, after the second rotating shaft 3261 rotates through the transmission of the first pulley 3262, the belt 3264 and the second pulley 3263, the first rotating shaft 3221 is driven to rotate, and the first mounting cylinder 3222 is driven to rotate to an appropriate angle. At this time, the first mounting cylinder 3222 may be used as a positioning collar during drilling, so that the drill bit penetrates through the first mounting cylinder 3222 to drill the gas pipeline 100 as positioning, and then the second mounting cylinder 3223 is installed in a threaded manner, so that the embedded probe 210 is installed in the drill hole to complete the installation.

Example 3
In order to improve the convenience of installation, when two first installation seats 321 are installed, only the first strapping bands 323 can be automatically driven to be tightly bound and the angles of the embedded probes 210 can be automatically adjusted by pulling the two first installation seats to two sides, and according to the pipe diameter of the gas pipeline 100, when the two first strapping bands 323 are tightly bound, the distances and the angles of the two embedded probes 210 are automatically adjusted to proper positions, and embodiment 3 is provided;
the present embodiment is a modified description based on embodiment 2, specifically referring to fig. 1 to 8, the mounting apparatus 300 further includes a second mounting seat 310 disposed at a middle position of the pair of carrying mechanisms 320, where the second mounting seat 310 is mounted on the gas pipeline 100 by a second strapping 330;
the bearing mechanism 320 further comprises a driving component 327, and when the first mounting seat 321 is pushed away from the second mounting seat 310, the driving component 327 drives the first adjusting component 325 and the second adjusting component 326 to operate;
the driving assembly 327 includes a second rotating rod 3271 rotatably disposed on the first mounting seat 321, a first bevel gear 3272 is disposed on the second rotating rod 3271, second bevel gears 3273 are disposed on the first rotating shaft 3251 and the second rotating shaft 3261, and both second bevel gears 3273 are engaged with the first bevel gear 3272;

when the first mounting seat 321 is displaced in a direction away from the second mounting seat 310, the connecting rope 3274 drives the second rotating rod 3271 to rotate, so as to drive the first rotating shaft 3251 to rotate to drive the first strapping tape 323 to be strapped on the gas pipeline 100, and drive the second rotating shaft 3261 to rotate to drive the embedded probe 210 to deflect in a direction towards the second mounting seat 310.
In this embodiment: first, a second mount 310 is added and is placed on the gas pipeline 100 on the same horizontal line with the two first mounts 321. The two connecting ropes 3274 wound and mounted on the wire winding roller 340 in the second mounting seat 310 are symmetrically arranged, and are connected with the two first mounting seats 321 through the two connecting ropes 3274.
Taking the group of bearing mechanisms 320 located at the left side as shown in fig. 8 as an example, the connecting rope 3274 is extended along with the movement of the first mounting seat 321 to the left side, and will automatically drive the second rotating rod 3271 to rotate, the second rotating rod 3271 then drives the first bevel gear 3272 and the two second bevel gears 3273 to rotate, and then drives the first rotating shaft 3251 to rotate so as to drive the first strapping tape 323 to be tightly bundled, and drives the second rotating shaft 3261 to rotate so as to drive the embedded probe 210 to rotate for adjusting the angle.
The transmission ratio between the first pulley 3262 and the second pulley 3263 can control how much transmission ratio the second shaft 3261 is driven to rotate by the displacement of the first mounting seat 321 to drive the embedded probe 210 to rotate to a proper angle by specifically setting the diameters of the first pulley 3262 and the second pulley 3263.
It should be noted that the two in-line probes 210 may be installed in a transmission manner, that is, the two in-line probes 210 are located on two sides of the gas pipeline 100. Since the connection method is to use the connection rope 3274 which may be a wire rope or the like, the connection method is not affected even when one of the in-line probes 210 is rotated one turn.
The second strapping 330 may have the same structure as the first strapping 323, and only the second mounting base 310 may be fixed to each other.
Example 4
After the first strapping 323 is strapped onto the gas pipeline 100, the installation angles of the first installation cylinder 3222 and the embedded probe 210 are automatically adjusted in a rotating manner, and certain adjustment can be performed at this time, if a certain slight difference exists in the angle of the embedded probe 210 during actual adjustment, certain fine adjustment is required, so that embodiment 4 is proposed;

The first rotating rod 3221 can rotate to drive the first mounting cylinder 3222 to rotate through the fastening force of the threaded connection.
When fine adjustment is needed, the first rotating rod 3221 can be pinched to avoid rotation, and then the first mounting cylinder 3222 is twisted to drive the sleeve 3224 to rotate for a certain angle, so that the first mounting cylinder 3222 can be finely adjusted to rotate without reversely driving the first rotating rod 3221.
It should be noted that, to avoid displacement of the first mounting cylinder 3222 along the screw direction due to rotation of the relatively stationary first rotating rod 3221 during fine adjustment, the sleeve 3224 may be slidably mounted on the first mounting cylinder 3222, and the connection between the two may be a polygon between the second rotating rod 3271 and the rotating cylinder 3281, so that the sleeve 3224 may slide along the first mounting cylinder 3222 or may drive the first mounting cylinder 3222 to rotate.
Example 5
When the angle of the embedded probe 210 needs to be adjusted, the first strapping 323 is detached or rebinding, and the distance between the first mounting seats 321 is readjusted, the three movements are influenced by the mutual transmission due to the meshing of the first bevel gear 3272 and the second bevel gear 3273, for example, if the first strapping 323 is directly reversely slid out of the mounting groove 324 to release the fixation of the first mounting seats 321, the embedded probe 210 is driven to rotate, so as to solve the problem, embodiment 5 is proposed;
