[0002] The existing wind speed measurement device can only measure the wind speed at one measuring point in the air duct at a time. After each measurement, it is necessary to change the length extending into the air duct to measure the wind speed at different positions of the measuring points. There are also some wind speed measuring devices Although it is possible to measure the wind speed of multiple measuring points in the air duct, it can only be adapted to the corresponding diameter of the air duct. When measuring in the air duct of different diameters, it cannot ensure that the multiple measuring points are evenly distributed and equidistant. lead to inaccurate measurements

The invention discloses a wind pipe wind speed adaptive measurement device, which comprises a handle, multiple wind speed measurement heads, an ejection head and compression springs, wherein two endsof the handle are provided with a first connection head and a connection line; each wind speed measurement head is provided with a dual-head connection pipe; the multiple wind speed measurement headsare mutually connected; a telescopic pipe is connected between the dual-head connection pipes of each two adjacent wind speed measurement heads; the first wind speed measurement head is connected ontothe first connection head through one end of the dual-head connection pipe; the ejection head is provided with a second connection head, and the ejection head is connected with one end of the dual-head connection pipe on the last wind speed measurement head through the second connection head; and the compression spring is arranged between each two adjacent wind speed measurement heads. Accordingto the wind pipe wind speed adaptive measurement device, the distribution position of the multiple wind speed measurement heads can be automatically changed with the caliber of different wind pipes, the multiple wind speed measurement heads can constantly distributed uniformly and equidistantly, and the measurement result accuracy is ensured.
Description
technical field [0001] The invention belongs to the field of air duct wind speed detection equipment for boiler equipment, and in particular relates to an air duct wind speed self-adaptive measurement equipment. Background technique [0002] The existing wind speed measurement device can only measure the wind speed at one measuring point in the air duct at a time. After each measurement, it is necessary to change the length extending into the air duct to measure the wind speed at different positions of the measuring points. There are also some wind speed measuring devices Although it is possible to measure the wind speed of multiple measuring points in the air duct, it can only be adapted to the corresponding diameter of the air duct. When measuring in the air duct of different diameters, it cannot ensure that the multiple measuring points are evenly distributed and equidistant. lead to inaccurate measurement results.
