DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Please refer to Figs. 1-2The application discloses a lode weather vane with a breakable and fragile flagpole, which comprises a fragile flagpole 11, a base 1 and a wind vane 16. The lower end of the fragile flagpole 11 is reversibly arranged on the base 1. The fragile flagpole 11 is made of glass fiber reinforced polymer (GFRP) and is composed of multiple layers of fiber cloth and epoxy resin. The fragile flagpole 11 is hollow in the middle to reduce the weight. The middle part of the fragile flagpole 11 is hollow. The diameter of the fragile flagpole 11 decreases from the bottom to the top, that is, the bottom is thicker and the top is thinner. The design forms a cross-section mutation at each diameter change node. According to the Saint-Venant principle, the cross-section mutation causes local stress concentration. When the fragile flagpole 11 is subjected to axial tension, pressure or bending moment, the stress at the node increases significantly and exceeds the material strength limit, thereby causing stress concentration at the node.

[0026] Stress concentration usually occurs at places where the geometric shape changes suddenly, such as steps, holes and grooves. When the fragile flagpole 11 is subjected to external forces such as axial tension, pressure or bending moment, the cross-section change at the nodes causes uneven stress distribution, and the stress in the local area increases significantly, exceeding the material strength limit, thereby breaking at the nodes.

[0027] The outer side of the lowermost fragile flagpole 11 is fixed with a box 13. Users can set some control boxes. The prior art is mature, and thus will not be described one by one. The upper end of the fragile flagpole 11 is fixedly connected with a spotlight 17 and an aviation obstruction light 18, which provide guidance for the cruising of an airplane. The outer side of the uppermost fragile flagpole 11 is rotatably connected with the wind vane 16, which is used for testing the wind direction. The base 1 is fixed on the ground.

[0028] Specifically, the fragile flagpole 11 is detachably arranged on the mounting plate 2. The lower end of the mounting plate 2 and the upper end of the base 1 are fixedly connected with two mounting blocks 3, respectively. The mounting blocks 3 are rotatably connected with a mounting shaft 4. That is, after the base 1 is fixedly mounted on the ground, the mounting plate 2 can rotate around the mounting shaft 4 when it needs to be rotated, and the fragile flagpole 11 is laid down.

[0029] Specifically, the upper end surface of the base 1 is fixedly connected with a supporting block 6. The supporting block 6 supports the mounting plate 2 in a horizontal position to avoid tilting. The mounting plate 2 is inserted with an inserting piece 7. The inserting piece 7 can be inserted into the supporting block 6. The inserting piece 7 can be screwed into the supporting block 6 by a bolt or directly inserted into the supporting block 6 as a plug rod, as long as the friction between the inserting piece 7 and the supporting block 6 is ensured.

[0030] Specifically, the mounting plate 2 is detachably provided with a flange plate 8. The upper end of the flange plate 8 is fixedly connected with a sleeve 9. The lower end of the fragile flagpole 11 is inserted into the sleeve 9. The sleeve 9 and the lower end of the fragile flagpole 11 are both provided with threaded holes 10 for screwing bolts.

[0031] Specifically, the uppermost frangible rod 11 is rotatably connected with a circular ring 15, and the wind vane 16 is fixedly connected to the circular ring 15. The inner side of the circular ring 15 is fixedly installed with a bearing, and the inner side of the bearing is fixedly connected to the outer side of the frangible rod 11, so as to improve the sensitivity of the rotation of the wind vane 16.

[0032] Specifically, the back of the box 13 is fixedly connected with a hoop 12, which is detachably installed on the outer side of the lowermost frangible rod 11. Alternatively, a U-shaped clamp can also be used.

[0033] Specifically, the four corners of the base 1 are provided with mounting holes 5 for fixing the base 1 to the ground at the installation position.

[0034] Specifically, the lower end of the box 13 is fixedly connected with a wire tube 14.

[0035] Specifically, the frangible rod 11 is hollow inside, which reduces the overall weight of the frangible rod 11 and makes it easier to break.

[0036] Specifically, the frangible rod 11 is made of glass fiber material, which is lighter in overall material.

[0037] Installation position:

[0038] It should be installed at key positions such as both ends of the runway, the edge of the taxiway, and the apron, so as to provide the most effective wind information for pilots. The direction of the frangible rod 11 should be along the flight trajectory of the aircraft.

[0039] When installing, it should be ensured that the wind vane 16 maintains a certain height above the ground to facilitate the observation of pilots and avoid collision with ground obstacles.

[0040] Function test:

[0041] After installation is completed, the wind vane 16 should be tested for function to ensure that it can accurately indicate the wind direction.

[0042] The direction of the wind vane 16 can be observed by using a small fan or other equipment to generate artificial wind near the wind vane 16.

[0043] Daily maintenance:

[0044] The wind vane should be cleaned regularly to remove dust, bird droppings, and other pollutants, and to keep its surface clean.

[0045] When cleaning, mild detergent and soft cleaning tools should be used to avoid damaging the wind vane.

[0046] The rotation flexibility and stability of the wind vane 16 should be checked regularly to ensure that it can work normally.

[0047] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and the patent protection scope of the present application is subject to the claims, and any equivalent structural changes made by using the content of the specification and drawings of the present application should also be included in the protection scope of the present application.
