Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of medical devices, specifically relating to a wind direction identification device for navigation. Background Technology
[0002] Navigation is the activity of humans sailing across oceans to travel from one landmass to another. During navigation, sea winds have a significant impact on ships, even affecting their course. Therefore, wind direction detection devices are needed to determine wind direction and adjust the ship's course accordingly.
[0003] However, nowadays, wind direction identification devices need to be calibrated during installation to ensure they are perpendicular to the horizontal plane. If the installation is tilted, the swaying amplitude of the device will be amplified due to the asymmetrical structure when the ship rocks, which will exacerbate mechanical wear or signal noise. At the same time, its own coordinate system will deviate from the horizontal plane, resulting in a geometric projection error between the detected wind direction angle and the actual wind direction. Utility Model Content
[0004] Purpose of the utility model: To provide a wind direction identification device for navigation, so as to solve the above-mentioned problems existing in the prior art.
[0005] Technical solution: A wind direction identification device for navigation, comprising a main body, the main body including a support frame, a wind vane disposed in the middle of the support frame and a wind speed mark disposed at the bottom, a base disposed at the bottom of the main body, the base being fixed to the hull, a plurality of screws arranged in an array on the base, the plurality of screws being connected to the main body through a calibration plate, the calibration plate having a plurality of slots arranged in a ring, the plurality of slots corresponding one-to-one with the plurality of screws, each screw being provided with two nuts, the two nuts being respectively disposed on both sides of the calibration plate.
[0006] In a further embodiment, a plurality of vertical support rods are provided on the side of the calibration disk away from the base, and a base is connected to the plurality of support rods, on which a horizontally rotating vertical calibrator is provided.
[0007] In a further embodiment, the vertical calibrator is provided with a turntable that rotates with the base, and the turntable is provided with a scale ring facing the calibration disk. The scale ring is perpendicular to the base. A swing plate is provided at the center of the turntable, and a first calibration needle that cooperates with the scale ring is provided on the swing plate.
[0008] In a further embodiment, the scale ring is provided with corresponding degrees, with the bottommost point being 0°.
[0009] In a further embodiment, a calibration rod is provided at the center of the lower end of the support frame, the calibration rod corresponds to the swing plate, and a second calibration needle corresponding to the calibration rod is provided at the end of the swing plate.
[0010] In a further embodiment, a positioning sleeve is provided on the support frame, the lower end of the support frame corresponds to the turntable, and the positioning sleeve and the turntable are respectively provided with male and female threads.
[0011] In a further embodiment, a glass cover is provided on the base, the vertical calibrator is disposed between the glass cover and the base, and a glass window corresponding to the calibration rod is provided on the support frame.
[0012] In a further embodiment, the base has a threaded hole, the turntable has a positioning hole corresponding to the threaded hole, and a screw is disposed in the threaded hole.
[0013] The beneficial effects of this utility model are:
[0014] 1) When the device needs to be installed, the operator attaches the base to the desired location using expansion bolts or by direct welding. Then, the operator screws nuts onto the threaded rods on the base, aligns the slots on the calibration plate with the screws, and screws nuts onto the screws again. By rotating the turntable, the swing plate can be aligned with different directions. By screwing the nuts below the calibration plate, the first and second calibration pins on the swing plate are aligned with 0° on the scale ring and calibration rod, respectively, making the main body perpendicular to the horizontal plane. Finally, by screwing the nuts above the calibration plate, the calibration plate is tightened, thus completing the installation and improving the operator's installation efficiency.
[0015] 2) When the first calibration needle and the 0° on the scale ring are different from the second calibration needle and the calibration rod, it is determined that the main body itself has an angular error. Then, by turning the positioning sleeve, since the positioning sleeve and the turntable are equipped with corresponding male and female threads, the main body can be quickly disassembled for maintenance.
[0016] 3) At the same time, when calibrating the wind direction identification device, the first and second calibration needles on the swing plate are observed through the glass cover and glass window. The glass cover and glass window can prevent the calibration environment of the swing plate from being affected by the natural environment, thereby reducing the working time of the staff.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0024] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0025] It should be noted that in practical applications, due to limitations in equipment precision or installation errors, achieving absolute parallelism or perpendicularity is difficult. The descriptions of "perpendicular," "parallel," or "in the same direction" in this application are not absolute limitations, but rather indicate that a vertical or parallel structural arrangement can be achieved within a preset error range, achieving the corresponding preset effect. This maximizes the technical effect of the defined features and makes the corresponding technical solution easy to implement, possessing high feasibility. For example, "perpendicular" includes absolute perpendicularity and near-perpendicularity, where the acceptable deviation range for near-perpendicularity can be, for example, within 5°. "Parallel" includes absolute parallelism and near-parallelism, where the acceptable deviation range for near-parallelism can also be, for example, within 5°. "In the same direction" includes absolute same direction and near-same direction, where the acceptable deviation range for near-same direction can also be, for example, within 5°.
[0026] like Figures 1 to 4 The wind direction identification device for navigation shown includes a main body 1, which includes a support frame 2. A wind vane 3 is set in the middle of the support frame 2 and a wind speed mark 4 is set at the bottom. A base 5 is set at the bottom of the main body 1 and is fixed to the hull. Several screws 6 are arranged in an array on the base 5. The screws 6 are connected to the main body 1 through a calibration plate 7. Several slots 8 are arranged in a ring on the calibration plate 7. The slots 8 correspond one-to-one with the screws 6. Two nuts 9 are set on each screw 6. The two nuts 9 are respectively set on both sides of the calibration plate 7.
[0027] It should be noted that the base 5 is attached to the installation position by expansion bolts or welding. By setting the calibration plate 7 as described above, the distance between the nuts 9 on several screws 6 can be adjusted up and down to adjust the angle of the calibration plate 7 so that it is horizontal, thereby making the support frame 2 perpendicular to the horizontal plane.
[0028] In a further embodiment, a plurality of vertical support rods 10 are provided on the side of the calibration disk 7 away from the base 5. A base 11 is connected to the plurality of support rods 10. A horizontally rotating vertical calibrator 12 is provided on the base 11. The vertical calibrator 12 is provided with a turntable 13 that rotates with the base 11. A scale ring 14 facing the calibration disk 7 is provided on the turntable 13. The scale ring 14 is perpendicular to the base 11. A swing plate 15 is provided at the center of the turntable 13. A first calibration needle 16 that cooperates with the scale ring 14 is provided on the swing plate 15. The scale ring 14 is provided with corresponding degrees, with its lowest point being 0°.
[0029] By setting a rotatable vertical calibrator 12 on the calibration disk 7, when adjusting the level of the calibration disk 7, the turntable 13 is rotated so that the swing plate 15 on the turntable 13 can swing in the east-west or north-south direction. When the calibration disk 7 is adjusting the angle, the swing plate 15 is vertically downward under its own weight. When the first calibration pin 16 on the swing plate 15 corresponds to 0° on the scale ring 14, the level calibration of the calibration disk 7 is successfully achieved.
[0030] In a further embodiment, a calibration rod 17 is provided at the center of the lower end of the support frame 2. The calibration rod 17 corresponds to the swing plate 15, and a second calibration needle 18 corresponding to the calibration rod 17 is provided at the end of the swing plate 15.
[0031] By setting the second calibration needle 18 to correspond with the calibration rod 17 at the center of the lower end of the support frame 2, when the first calibration needle 16 corresponds to 0° on the scale ring 14, the second calibration needle 18 should be parallel to the calibration rod 17, thereby achieving final calibration. If the second calibration needle 18 deviates after the first calibration, it can be determined that the main body 1 has a positional deviation, and then it can be disassembled and maintained.
[0032] In a further embodiment, a positioning sleeve 19 is provided on the support frame 2, the lower end of the support frame 2 corresponds to the turntable 13, and the positioning sleeve 19 and the turntable 13 are provided with male and female threads respectively. A threaded hole is opened on the base 11, and a positioning hole corresponding to the threaded hole is opened on the turntable 13. A screw is provided in the threaded hole.
[0033] The support frame 2 is fixedly connected to the turntable 13 through the positioning sleeve 19, thereby achieving the effect of positioning the support frame 2. At the same time, after calibration, the screws are screwed into the positioning holes so that the screws can fix the turntable 13 to prevent rotation, thereby preventing it from affecting the subsequent identification operation of the wind direction identification shaft.
[0034] In a further embodiment, a glass cover 20 is provided on the base 11, a vertical calibrator 12 is disposed between the glass cover 20 and the base 11, and a glass window 21 corresponding to the calibration rod 17 is provided on the support frame 2.
[0035] By setting up the glass cover 20 and the glass window 21, the first calibration needle 16 and the second calibration needle 18 on the swing plate 15 can be observed through the glass window 21 and the glass cover 20 during vertical calibration, while preventing the calibration environment of the swing plate 15 from being affected by the natural environment, thereby reducing the working time of the staff.
[0036] Working principle explanation:
[0037] When the device needs to be installed, the operator attaches the base 5 to the desired location using expansion bolts or by direct welding. Nuts 9 are then tightened onto the threaded rods on the base 5. The slots 8 on the calibration disc 7 are aligned with the screws 6, and nuts 9 are tightened onto the screws 6 again. By rotating the turntable 13, the swing plate 15 can be aligned to different directions. Tightening the nuts 9 below the calibration disc 7 aligns the first calibration needle 16 and the second calibration needle 18 on the swing plate 15 with the 0° mark on the scale ring 14 and calibration rod 17, respectively, ensuring the main body 1 is perpendicular to the horizontal plane. Finally, tightening the nuts 9 above the calibration disc 7 completes the installation. If the first calibration needle 16 aligns with the 0° mark on the scale ring 14, or if the second calibration needle 18 deviates from the calibration rod 17, it is determined that the main body 1 has an angular error. Tightening the positioning sleeve 19, which has corresponding male and female threads on the turntable 13, allows for quick disassembly of the main body 1 for maintenance. Meanwhile, when calibrating the wind direction identification device, the first calibration needle 16 and the second calibration needle 18 on the swing plate 15 are observed through the glass cover 20 and the glass window 21. At the same time, the glass cover 20 and the glass window 21 can prevent the calibration environment of the swing plate 15 from being affected by the natural environment, thereby reducing the working time of the staff.

Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
