Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1-3, the utility model provides a modularization amount of wind measuring device in large-scale wind channel of power station, including amount of wind measuring machine 1 and tuber pipe 2, the tip fixed surface who is close to amount of wind measuring machine 1 of tuber pipe 2 is connected with dead lever 6, the fixed half-turn 5 of one end fixedly connected with of dead lever 6, the last sliding surface of fixed half-turn 5 is connected with activity half-turn 4, slider 13 of the equal fixedly connected with in both ends bottom of activity half-turn 4, the upper surface of fixed half-turn 5 seted up with slider 13 assorted slide 7, and the one end of slide 7 runs through the tip surface of fixed half-turn 5.

In an optional embodiment, two ends of the fixed half-ring 5 are movably sleeved with a push rod 8, and a rectangular through groove 12 matched with the push rod 8 is formed in the slide block 13.

In an alternative embodiment, two pairs of limit stops 11 are symmetrically and fixedly connected to the end of the push rod 8 located inside the slide 7, and the two pairs of limit stops 11 are respectively disposed on the left and right sides of the slide 13.

In an alternative embodiment, a plurality of screw holes 10 are formed on one side surface of the push rod 8, and a bolt 9 capable of being screwed with the screw holes 10 is rotatably connected to the outer surface of the end portion of the fixing half-ring 5.

In an optional embodiment, one end of the air volume measuring machine 1 is fixedly connected with an air duct connector 3, and the air duct connector 3 is fixedly butted with the bottom end of the air duct 2.

The working principle is as follows: when the traditional modularized air volume measuring device for the large air duct of the power station is connected with an air duct, the bottom end position of the air duct lacks a fixed supporting device, so that the joint of the air duct and the measuring device is not firm enough, in the embodiment, the bottom end position of the air duct 2 is convenient to draw and support through the design of the movable half ring 4, the fixed half ring 5 and the fixed rod 6, so that the air duct 2 is kept not easy to deform during ventilation, and the connection between the bottom end of the air duct 2 and the air duct connector 3 is more stable; in the scheme, the movable half ring 4 and the fixed half ring 5 are mutually spliced to clamp the air pipes 2 with different pipe diameters, so that the applicability is wider; specifically, firstly, the movable half ring 4 slides to the position shown in fig. 2 through the sliding connection between the sliding block 13 and the sliding way 7, then the movable half ring 4 is drawn close to the fixed half ring 5 until the inner ring surfaces of the movable half ring 4 and the fixed half ring 5 are tightly attached to the outer surface of the air pipe 2, then the push rod 8 is pushed to enable the end part of the push rod 8 to be inserted into the rectangular through groove 12, then the push rod 8 is rotated by 90 degrees, two pairs of limit stops 11 are respectively rotated to the positions shown in fig. 3, so that the sliding block 13 cannot be separated from the end part of the push rod 8, then the bolt 9 is rotated, and the movable half ring 4 is limited through the screw thread between the bolt 9 and the screw hole 10 at the corresponding position.
