Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 3 This utility model discloses a wind speed sensor that is easy to maintain. It includes a mounting housing 1 with a circular opening at the top. A connecting key tube 21 is rotatably mounted on the mounting housing 1. Connecting bearings 221 are provided at both ends of the connecting key tube 21. The upper end of the connecting key tube 21 is located at the circular opening of the mounting housing 1. A fan shaft key tube 22 is slidably connected inside the connecting key tube 21. A connecting fan cap 31 is fixedly mounted on the upper end of the fan shaft key tube 22. The upper end of the connecting fan cap 31 has a circumferential array. The column has three T-slots 311, and T-blocks 321 are inserted into the T-slots 311. The wind cup 32 is fixedly connected to the T-blocks 321. The upper end of the connecting fan cap 31 is threadedly connected to a fixing ring 33. After the fixing ring 33 is tightened, it fits into the T-blocks 321. The inner ring of the connecting bearing 221 is fixedly installed with a fixing nut 41. The fixing nut 41 is threadedly connected to a fixing screw 42. The fixing screw 42 passes through the fan shaft key tube 22. The connecting key tube 21 is connected to the wind speed sensor module 5.

[0028] Specifically, the wind cup 32 is connected to the connecting fan cap 31. When airflow passes through, the wind cup 32 rotates, causing the connecting fan cap 31 to rotate, which in turn causes the fan shaft key tube 22 to rotate. The fan shaft key tube 22 is keyed to the connecting key tube 21, causing the connecting key tube 21 to rotate. The connecting key tube 21 drives the wind speed sensor module 5 to rotate. After the sensor in the wind speed sensor module 5 senses the rotation speed, it transmits the data to the display terminal. The terminal calculates and obtains the wind speed.

[0029] The wind cup 32 is inserted and fixed by the retaining ring 33. The fan cap 31 is fixed by the retaining screw 42 and the retaining nut 41. When it is necessary to replace or maintain related parts, it can be removed by disassembling the retaining screw 42 and the retaining ring 33, which is convenient for replacement and maintenance.

[0030] In some feasible configurations, the mounting shell 1 is cylindrical. For ease of installation, the mounting shell 1 includes two half-shells 11, which are bolted together. A sealing strip is provided on the side of the half-shells 11 that is in contact with each other. A spline is provided inside the connecting key tube 21. Both ends of the connecting key tube 21 are fixedly connected to the inner ring of the connecting bearing 221. A semi-annular groove is provided inside the half-shell 11, and the connecting bearing 221 is fixed in the semi-annular groove. The inner ring of the lower end of the connecting bearing 221 is welded to the fixing nut 41. A spline is provided on the outside of the fan shaft key tube 22. The connecting fan cap 31 is cylindrical. After the fixing screw 42 is tightened, the fan shaft key tube 22 is axially fixed. The upper end of the connecting fan cap 31 is threaded. After the T-shaped block 321 of the wind cup 32 is inserted into the T-shaped groove 311, the fixing ring 33 rotates and locks.

[0031] As one specific embodiment of the wind speed sensor provided in the application for easy maintenance, the upper circular opening of the mounting shell 1 extends upward to form a neck, and the connecting fan cap 31 is rotatably fitted onto the neck.

[0032] Overall, by setting the connecting fan cap 31 to be fitted around the neck, a certain degree of protection is provided for the neck area, reducing the possibility of rainwater or other substances entering the connecting key tube 21.

[0033] In some feasible methods, the lower end of the connecting fan cap 31 is provided with an annular groove, which is then fitted onto the neck.

[0034] As another specific embodiment of the wind speed sensor provided in the application for easy maintenance, the upper end of the fixing screw 42 is set as conical, and the bottom diameter of the upper end of the fixing screw 42 is larger than the outer diameter of the fixing ring 33.

[0035] Depending on the specific application scenario, the upper end of the conical fixing screw 42 is set to shield the T-slot 311, reducing the possibility of rainwater entering the T-slot 311.

[0036] Furthermore, semi-annular grooves are provided at both ends of the fixing ring 33, and sealing rings 331 are installed in the semi-annular grooves. The upper end of the fixing screw 42 is attached to the sealing ring 331 at the upper end of the fixing ring 33.

[0037] It should be understood that by setting the sealing ring 331, rainwater erosion is further reduced and service life is improved.

[0038] In some feasible methods, anti-slip strips are arranged in a circumferential array on the side of the upper end of the fixing screw 42 and the side of the fixing ring 33 to facilitate manual assembly and disassembly.

[0039] As a specific embodiment of the wind speed sensor provided in the application for easy maintenance, the end of the mounting housing 1 away from the wind cup 32 is provided with a connecting key tube 21, a fan shaft key tube 22, a connecting fan cap 31, a fixing ring 33, a fixing nut 41, a fixing screw 42, a T-block 321 and a T-slot 311. There are two T-blocks 321, and the two T-blocks 321 are respectively fixedly connected to the tail blade 61 and the index 62. The connecting key tube 21 is connected to the wind direction sensor module 63.

[0040] It should be understood that by setting the tail rotor blade 61 and the pointer 62, it is convenient to indicate the wind direction.

[0041] In some feasible ways, the structure of the pointer 62 part is the same as that of the wind cup 32 part, and the wind direction sensor module 63 can be selected as an angle sensor. By setting the initial position of the pointer 62, the wind direction can be obtained by rotating the angle.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
