Air quantity harvester of the present utility model, including square airduct, radially extend and outer end be connected to described square Many total head sampling pipes on airduct, radially extend and outer end be connected to belonging to many static pressure sampling pipes on square airduct, The average cavity that is fixedly connected with the inside end phase of many total head sampling pipes and static pressure sampling pipe respectively, it is connected with average cavity output end Electrical appliance kit, described total head sampling pipe and described static pressure sampling pipe are separately positioned at the axially distinct position of described airduct；Described Total head sampling pipe includes complete along the diagonal total head sampling pipe of described square airduct diagonal setting and remaining off-diagonal Pressure sampling pipe, described diagonal total head sampling pipe offers two thieff hatch, described off-diagonal total head in face of on the face of air-flow Sampling pipe offers 1 thieff hatch in face of on the face of air-flow；Described static pressure sampling pipe is included along described square airduct diagonal side Diagonal static pressure sampling pipe and remaining off-diagonal static pressure sampling pipe to setting；Described diagonal static pressure sampling pipe carry gas Two thieff hatch are offered, described off-diagonal static pressure sampling pipe is carried and offered 1 thieff hatch on the face of air-flow on the face of stream.

Further, it is separated into total head average cavity with average cavity dividing plate in the inner chamber that described average cavity is formed and static pressure is put down All chambeies, the inner chamber of described total head sampling pipe is connected with total head average cavity, and the described inner chamber of static pressure sampling pipe is average with static pressure Chamber is connected.

Further, it is connected with spring between the outer end of described total head sampling pipe and airduct madial wall, described static pressure is adopted It is connected with spring between the outer end of sample pipe and airduct madial wall.

Further, described airduct two ends are provided with the flange for being connected with external pipe.

By such scheme, the utility model at least has the advantage that

By air quantity harvester on-line equipment in square airduct, and combine square airduct structure, to sampling pipe With thieff hatch reasonable Arrangement, thus simplifying device structure, and reduce equipment cost, and it is square so that each thieff hatch is uniformly distributed in On pipeline section, thus improving the accuracy of measurement.

Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model Art means, and being practiced according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing detailed Describe in detail bright as after.
