[0030] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0032] like Figure 1 , Figure 2 , Figure 4As shown, this embodiment mainly includes a wind speed detection mechanism and a wind speed detection fixture for fixing the wind speed detection mechanism. The wind speed detection fixture includes a base 1 and a magnetic base 2 connected thereto. The magnetic base 2 is arranged on one side of the base 1. The upper end surfaces of the base 1 and the magnetic base 2 are both in the same horizontal plane. The base 1 is used to fix the wind speed detection mechanism 7. The wind speed detection mechanism 7 is composed of three parts: a wind speed detector 71, an anemometer test rod 72 and a probe 73. The probe 73 is installed at the front end of the anemometer test rod 72. The probe 73 is electrically connected to the wind speed detector 71. The probe 73 is used to detect the wind speed. The wind speed detector 71 can display the measured wind speed data information.

[0033] The base 1 and the magnetic base 2 jointly define an anemometer rod slot 11, an anemometer wire slot 12 is provided at one end of the anemometer rod slot 11, and the other end of the anemometer wire slot 12 extends to the side end surface of the magnetic base 2. The anemometer rod slot 11 is connected to the anemometer wire slot 12, and the anemometer rod slot 11 is used to place the anemometer test rod 72. The end of the anemometer test rod 72 away from the probe 73 is abutted against the lower end of the anemometer rod slot 11 (that is, the end close to the anemometer wire slot 12), and the anemometer wire slot 12 is used to place the wiring harness connecting the anemometer test rod 72 and the wind speed detector 71.

[0034] The magnetic base 2 is an electromagnet structure, and the base 1 is a plastic structure. The plastic structure is used to make the overall structure lighter. The magnetic base 2 is used to enable the product to be fixed in a metal air duct to avoid the need to hold the anemometer test rod 72 by hand for detection.

[0035] The interior of the air duct 6 is an air cavity, and the probe 73 is located in the flow path of the wind in the air cavity. The wind speed can be tested through the probe 73.

[0036] refer to Figure 1 and Figure 5 A laser rangefinder 3 is arranged on the base 1, and the laser rangefinder 3 is arranged directly opposite to the center of the anemometer rod slot 11 to measure the length of the anemometer test rod 72. The anemometer test rod 72 is a telescopic rod that can be extended or shortened. A reflective sheet 8 is arranged at the telescopic end of the anemometer test rod 72 (i.e., the end where the probe 73 is located), and the reflective sheet 8 extends outward along the radial direction of the anemometer test rod 72. During the wind speed detection process, the probe at the end of the anemometer test rod 72 is sent to a specified position inside the air duct, and the laser rangefinder 3 will emit a laser, which will be reflected by the reflective sheet 8 and re-emitted to the laser rangefinder 3. After receiving the reflected laser, the laser rangefinder 3 will calculate the distance between the transmitting end and the reflecting end, i.e., the telescopic length of the anemometer test rod 72.

[0037] Through the digital display function of the laser rangefinder 3, the length of the anemometer test rod 72 can be directly read to ensure that the probe is in the correct position. The anemometer wire groove 12 is set to avoid interfering with the measurement of the laser rangefinder 3. Setting the wire groove can make the measurement more orderly and efficient.

[0038] A horizontal detection mechanism 5 is arranged on the base 1, and the horizontal detection mechanism 5 includes a first horizontal detection mechanism 51 and a second horizontal detection mechanism 52, wherein the second horizontal detection mechanism 52 is arranged on the bottom surface of the base 1, and the first horizontal detection mechanism 51 is arranged on the side surface of the base 1 (that is, the surface perpendicular to the bottom surface of the base). When the anemometer test rod 72 extends from the bottom of the air duct 6, the first horizontal detection mechanism 51 is used to measure whether the anemometer test rod 72 is vertical, and the second horizontal detection mechanism 52 is used to measure whether the anemometer test rod 72 is horizontal.

[0039] There are usually two installation methods for the wind speed detection fixture. One is to be adsorbed on the bottom or top of the air duct 6. In this case, a first horizontal detection mechanism 51 is required to measure whether the anemometer test rod 72 is vertical. The other is to be adsorbed on the side of the air duct 6. In this case, a second horizontal detection mechanism 52 is required to measure whether the anemometer test rod 72 is horizontal to ensure that the anemometer test rod 72 is perpendicular to the bellows 6.

[0040] Only when the anemometer test rod 72 and the bellows 6 are vertically arranged, the values ​​measured at different points by telescopic length at one position are accurate; if the anemometer test rod 72 is tilted, the length of the extension into the bellows 6 is uncertain, resulting in a deviation between the extended air intake position and the predetermined point, and there will be errors in the measurement. The horizontal detection mechanism 5 is arranged on both end faces, so that when the wind speed detection is limited by the on-site conditions, holes can be opened on multiple faces of the air duct, and the anemometer test rod 72 can be inserted into the interior of the air duct through the openings. It can also ensure whether it is vertically arranged, which increases the feasibility of different working conditions.

[0041] A fixing knob 42 is also provided on the base 1, one end of which is connected to a fixing screw 41, which extends into the anemometer rod slot 11. When the anemometer test rod 72 is placed in the slot, the fixing knob 42 is turned so that the fixing screw presses against the anemometer test rod 72 for fixing. In this example, the depth and width of the anemometer rod slot 11 are greater than the width and height of the anemometer test rod 72 used, so that different types of anemometers can be accommodated.

[0042] A magnetic switch 21 is also provided on one side of the magnetic seat 2. The magnetic switch 21 is connected to the coil in the magnetic seat 2. The magnetic switch uses the change of the magnetic poles of the coil to control whether the magnetic seat 2 has suction, so that it can be fixed outside the bellows 6 without holding the contact to insert it into the bellows 6.

[0043] A laser switch 31 is also provided on one side of the laser speed meter. The laser switch 31 is arranged on the base 1. The laser rangefinder 3 switch can be turned off when not in use to avoid power consumption.

[0044] like Figure 3 As shown, when in use, turn on the magnetic switch 21, fix the magnetic seat 2 with the fixing seat on the bellows 6, and then adjust the magnetic seat 2 according to the indication of the horizontal display setting so that the end face where the laser rangefinder 3 is located is perpendicular to the bellows 6, and two horizontal displays can be used for joint judgment, and then the end contact of the anemometer test rod 72 is inserted into the bellows 6, turn on the laser switch 31, and make the laser rangefinder 3 work. By judging the length of the anemometer test rod 72, the position of the contact is judged to ensure the accuracy of the entry point. After the fixing seat is fixed, the anemometer test rod 72 is extended to different depths in the bellows 6 through telescopic extension. Then, the anemometer tester 7 is held by hand to read the reading, and the data of 3-5 points can be tested, avoiding hand shaking and reducing the pressure of long-term handheld equipment detection on the inspector.

They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
