In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0031] See also Figure 1-Figure 4 The wind speed measuring bracket provided by the present invention is mainly used to measure the wind speed and air volume of air conditioning. Specifically, the wind speed measuring bracket can be used to measure the wind speed and air volume of the air conditioning system of rail transit.

[0032] The wind speed measurement bracket includes a support rod 1, a cross beam 4 and a support assembly 5. Among them, both ends of the support rod 1 are provided with connecting holes. Connecting rods 3 are fixed at both ends of the cross beam 4, and the connecting rods 3 can be inserted into the connecting holes. That is, the connecting rods 3 fixed at both ends of the cross beam 4 can be respectively inserted into the connecting holes at both ends of the support rod 1. The distance between the support rod 1 and the cross beam 4 can be adjusted by adjusting the distance of the connecting rod 3 inserted into the connecting hole. After the connecting rods 3 fixed at both ends of the cross beam 4 are respectively inserted into the connecting holes at both ends of the support rod 1, the cross beam 4 and the support rod 1 are arranged parallel to each other.

[0033] The support assembly 5 is arranged on the support pole 1, or the support assembly 5 is arranged on the cross beam 4. Alternatively, the support assembly 5 is arranged on the support pole 1 and the cross beam 4, in other words, a part of the support assembly 5 is connected to the support pole 1 and another part is connected to the cross beam 4. The support assembly 5 is used to support the wind speed sensor.

[0034] The number of the supporting components 5 can be one or more, and the number of the supporting components 5 can be set according to actual needs and is not limited here.

[0035] When using the wind speed measuring bracket provided in the above embodiment, the connecting rods 3 fixed at both ends of the cross beam 4 are respectively inserted into the connecting holes at both ends of the support rod 1, and then the wind speed sensor is set on the support assembly 5, and the wind speed measuring bracket is fixedly installed at the position of the wind speed and air volume to be measured.

[0036] The wind speed measurement bracket provided by the present invention can fix and position the wind speed and air volume test probes of the air conditioning system of the rail vehicle, solving the problem of unstable and inaccurate test results caused by handheld testing; the device is quick and simple to disassemble and assemble, and its small size after disassembly makes it easy to carry. The number of measuring points can be adjusted at will according to the size of the specific test wind tube and the number of anemometer probes, and it can be assembled at will on site. Moreover, after the wind speed measurement bracket is fixed, no other operations are required during the test process, which saves personnel costs. At the same time, since there is no human factor affecting the test results, the probability of repeated testing is reduced, and the test efficiency is improved.

[0037] Specifically, the wind speed measurement bracket can be fixedly installed on the inner wall of the test wind tube. According to actual conditions, multiple wind speed measurement brackets can be provided, and multiple support components 5 are provided on each wind speed measurement bracket, which is not limited here.

[0038] In a specific embodiment, the connecting rod 3 and the cross beam 4 can be arranged vertically. In this way, the distance between the support rod 1 and the cross beam 4 can be adjusted by adjusting the distance that the connecting rod 3 extends into the connecting hole, and finally the position adjustment of the support assembly 5 and the wind speed sensor in the longitudinal direction is achieved, where the longitudinal direction refers to the direction parallel to the wind direction.

[0039] Of course, the angle between the connecting rod 3 and the cross beam 4 may also be an acute angle, which is not limited here.

[0040] In order to prevent the connecting rods 3 fixed at both ends of the crossbeam 4 from being displaced when inserted into the connecting holes at both ends of the support rod 1, the connecting rod 3 is relatively fixed to the support rod 1 after being inserted into the connecting holes. In other words, after the connecting rod 3 is inserted into the connecting holes to a suitable position, the connecting rod 3 and the support rod 1 can be relatively fixed.

[0041] Furthermore, a plurality of elastic protrusions are arranged at intervals along the length direction of the connecting rod 3. In this way, the elastic protrusions can abut against the support rod 1 to limit the position of the connecting rod 3, and finally the connecting rod 3 and the support rod 1 can be relatively fixed.

[0042] Alternatively, an L-piece fixedly connected to both the support rod 1 and the connecting rod 3 may be provided to achieve relative fixation of the connecting rod 3 and the support rod 1. The L-piece is fixed to both the support rod 1 and the connecting rod 3 by screws.

[0043] In order to adapt to various types of wind tubes to be tested, the lengths of the support rod 1 and the crossbeam 4 can be adjusted. In order to facilitate adjusting the lengths of the support rod 1 and the crossbeam 4 according to the size of the wind tube to be tested.

[0044] Furthermore, the cross beam 4 and the support rod 1 may both be telescopic sleeve rods. Alternatively, the cross beam 4 and the support rod 1 may also include multiple sections of branch rods that are sequentially detachably fixedly connected, and the length of the cross beam 4 or the support rod 1 can be adjusted by adjusting the number of branch rods, which is not limited here.

[0045] In another specific embodiment, the support assembly 5 includes a first connecting member 5a disposed on the support rod 1 and a second connecting member 5b disposed on the crossbeam 4. Each support assembly 5 can support a wind speed sensor. The first connecting member 5a and the second connecting member 5b jointly support the wind speed sensor, the probe of the wind speed sensor is supported by the first connecting member 5a, and the body of the wind speed sensor is supported by the second connecting member 5b.

[0046] Further, the second connecting member 5b includes a first clamp 51 and a second clamp 52 that are fixedly connected. The axis of the first clamp 51 and the axis of the second clamp 52 are perpendicular to each other. The first clamp 51 is used to be fixedly connected to the beam 4, and the second clamp 52 is used to be connected to the wind speed sensor.

[0047] A slideway is provided on the support rod 1, and the second connecting member 5b is slidably matched with the slideway. The second connecting member 5b slides along the slideway, and the first clamp 51 slides along the crossbeam 4, so that the overall sliding of the support assembly 5 can be realized, thereby realizing the adjustment of the lateral position of the support assembly 5, where the lateral direction refers to the direction perpendicular to the wind direction.

[0048] In the above embodiment, while the second connecting member 5b is slidingly engaged with the slideway, the end of the second connecting member 5b is clamped in the slideway to prevent it from falling off.

[0049] In the above embodiment, one or more wind speed sensor probe handles can be fixed on the crossbeam 4 using the second connecting piece 5b, and the wind speed sensor probe can be stretched to the desired test position and passed through the supporting hole of the second connecting piece 5b so that the wind speed sensor probe is perpendicular to the incoming wind direction. The data can be read after it stabilizes to achieve stable and accurate measurement.

[0050] In order to facilitate the connection with the wind tube to be tested, connecting pieces 2 are fixed to both ends of the support rod 1. The connecting piece 2 and the wall of the wind tube to be tested can be connected by bolts, which is not limited here.

[0051] Of course, both ends of the support rod 1 may also be clamped or bonded to the wall of the wind tube to be tested, which is not limited here.
