Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas flow measurement technology, and more specifically, to a duct wind speed measurement device based on a multi-point sensor. Background Technology
[0002] An anemometer is an instrument used to measure the speed of air or gas flow. It converts the gas flow speed into a readable numerical value by detecting the motion characteristics of the airflow.
[0003] In existing wind speed detection instruments, the structure of the probe is generally fixed. When the probe enters the pipe through the test hole, it can only be distributed in a fixed position inside the pipe. The limited distribution of the probe means that it can only detect the position where the probe is located. The probe has a small acquisition area, making it difficult to accurately and comprehensively collect the wind speed in various parts of the duct. The measurement of wind speed on the duct surface often requires multi-hole testing, which is inconvenient for on-site operations. Utility Model Content

A fixed sleeve is fixedly installed at the end of the sliding rod away from the connecting seat. The sliding sleeve is threaded onto the outer circumference of the rotating long sleeve, and the sliding sleeve and the fixed sleeve are distributed vertically in correspondence.
[0014] In a preferred embodiment of this utility model, the rotation of the drive wheel drives the driven wheel to rotate synchronously with the rotating long sleeve, controlling the rotating long sleeve to rotate forward or backward.

[0020] This application controls the rotation of the drive wheel to freely control the forward or reverse rotation of the rotating long sleeve, thereby controlling the up and down displacement of the sliding sleeve.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0030] Example 1
[0031] See Figures 1-5 As shown, this utility model proposes a duct wind speed measuring device based on multi-point sensors, including: a wind speed measuring component 2 disposed on one side of the duct 1;
[0032] The wind speed measurement component 2 includes a connector 6 fixedly installed on one side of the air duct 1, and a measurement probe component 7 is provided at the bottom of the connector 6;
[0033] The measuring probe assembly 7 is installed inside the air duct 1.
[0034] According to the embodiments of this utility model, the operating states of the measuring probe assembly 7 include a contracted state and an expanded state;
[0035] When the wind speed test of duct 1 is performed, the measuring probe assembly 7 is in an expanded state, and the wind speed is tested on multiple test surfaces.
[0036] After the measurement is completed, control the measurement probe assembly 7 to return to the retracted state.
[0037] Specifically, the top surface of the wind speed measuring component 2 is provided with a connecting seat 6, and the free end of the connecting seat 6 is provided with a controllable and freely expandable measuring probe component 7. Before measurement, the measuring probe component 7 is in a retracted state. The connecting seat 6 extends into the air duct 1 through the measuring hole on the air duct 1 with the measuring probe component 7. After the measuring probe component 7 is distributed in the air duct 1, the measuring probe component 7 is controlled to expand. By controlling the expansion of the measuring probe component 7, the test surface of the measuring probe component 7 is increased.
[0038] According to an embodiment of the present invention, the wind speed measuring component 2 includes a rotating long sleeve 702 and a guide rod 704 disposed inside the rotating long sleeve 702. A driven wheel 10 is disposed on the top of the rotating long sleeve 702, and the guide rod 704 is disposed at the bottom center of the driven wheel 10.
[0039] According to an embodiment of the present invention, the wind speed measuring component 2 further includes a micro motor and a drive wheel 8. The drive wheel 8 is installed at the output end of the micro motor. Both the micro motor and the drive wheel 8 are located inside the connecting seat 6. The drive wheel 8 and the driven wheel 10 are connected by a transmission belt 9.
[0040] According to an embodiment of the present invention, the measuring probe assembly 7 includes a sliding rod 700, one end of which is connected to one end of a rotating long sleeve 702. A fixed sleeve 701 is fixedly installed at the end of the sliding rod 700 away from the connecting seat 6. A sliding sleeve 703 is threadedly installed on the outer circle of the rotating long sleeve 702. The sliding sleeve 703 and the fixed sleeve 701 are distributed vertically in correspondence.
[0041] According to the embodiment of this utility model, the rotation of the drive wheel 8 drives the driven wheel 10 to rotate synchronously with the rotating long sleeve 702, controlling the rotating long sleeve 702 to rotate forward or backward. During the rotation of the rotating long sleeve 702, the sliding sleeve 703 is displaced up and down, controlling the expansion state of the scissor frame 705.
[0042] Furthermore, multiple sets of guide rods 704 are fixedly installed between the connecting seat 6 and the fixed sleeve 701. Multiple sliding holes are provided through the sliding sleeve 703. The sliding sleeve 703 is slidably installed on the multiple sets of telescopic guide rods 704 through the sliding holes. In use, since the sliding sleeve 703 is threaded on the rotating long sleeve 702, by controlling the rotating long sleeve 702 to rotate forward or backward, the rotating long sleeve 702 controls the sliding sleeve 703 to slide up and down as it rotates forward or backward.
[0043] According to the embodiment of this utility model, the outer surfaces of the fixed sleeve 701 and the sliding sleeve 703 are provided with multiple pull ears, and a scissor bracket 705 is movably installed between the two sets of pull ears corresponding to the upper and lower parts. A side probe 706 is movably installed at the free end of the scissor bracket 705.
[0044] Specifically, when the test probe assembly is in the retracted state, multiple sets of side probes 706 are distributed close to the side of the sliding rod 700, greatly reducing the volume of the entire measurement probe assembly 7, thus facilitating the free entry and exit of the measurement probe assembly 7 into the test hole on the air duct 1.
[0045] According to an embodiment of the present invention, the scissor frame 705 includes a first connecting rod and a second connecting rod. The centers of the first connecting rod and the second connecting rod are hinged together by a hinge shaft and arranged in an X-shape. The two ends of the first connecting rod are respectively connected to the side probe 706 and the fixed sleeve 701, and the two ends of the second connecting rod are respectively connected to the side probe 706 and the sliding sleeve 703.
[0046] According to an embodiment of the present invention, the wind speed measuring component 2 is provided with a display screen 4 and multiple control buttons 3 on its top.
[0047] According to an embodiment of the present invention, a power cord 5 is provided on one side of the wind speed measuring component 2.
[0048] In summary, this application controls the rotation of the drive wheel 8 to freely control the forward or reverse rotation of the rotating sleeve 702, which in turn controls the vertical displacement of the sliding sleeve 703. This allows for flexible control of the expansion state of the scissor frame 705, thereby precisely controlling the simultaneous expansion of multiple sets of side probes 706. This enables the multiple sets of side probes 706 to come into contact with the airflow at different locations within the duct 1, thus allowing for the measurement of wind speed at different locations within the duct 1 and improving the accuracy of wind speed measurement within the duct 1.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
