Description

Technical Field

[0001] This utility model relates to the field of wind vanes, specifically to a wind vane device. Background Technology

[0002] The "Regulations for Safety and Health Design of Chemical Enterprises" clearly stipulates that wind vanes should be installed in areas with toxic and hazardous chemical production. Wind vanes are devices that determine the direction of wind, constantly indicating the direction of gas flow. They are widely used in areas with toxic and hazardous chemical production. Their function is to help people identify the direction and evacuate people against the wind in the event of a leak of hazardous chemicals from a chemical enterprise; they are an important safety sign.

[0003] During installation, wind vanes need to be placed at a relatively high position to ensure they are unobstructed and clearly visible, and steel pipes are often used as the pole material. Existing wind vanes mostly have poles fixed to a base that cannot be laid down. The height of the pole itself is generally much greater than the height of the operator. Therefore, when replacement is needed, a ladder must be built to reach the designated height, which brings inconvenience to wind vane replacement, affects construction efficiency, and poses a risk of falls. Summary of the Invention

[0004] To address the issue that existing wind vanes are mostly fixed to a base and cannot be laid down, and the height of the pole is generally much greater than the height of the operator, replacement requires climbing a ladder to the designated height, which is inconvenient, affects construction efficiency, and poses a risk of falling. This utility model proposes a wind vane device that allows the pole to be laid down for easy replacement of the wind vane without having to climb to a high place, and is safe, labor-saving, and convenient.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A weather vane device includes a base, a pole, a pole head, and a tail fin. An adjustment assembly is provided between the pole and the base. The adjustment assembly includes a first fixed plate and a second fixed plate arranged opposite to each other. A rotating shaft is rotatably arranged between the first fixed plate and the second fixed plate. A rotating rod is fixedly sleeved on the rotating shaft. A positioning hole is provided on the rotating rod. A horizontally movable insertion rod is provided on the first fixed plate. The insertion rod passes through the first fixed plate and is inserted into the positioning hole.

[0007] Furthermore, a vertical shaft is rotatably connected to the top of the pole, and a horizontal bar is mounted on the top of the vertical shaft. The pole head is arrow-shaped and located at the front end of the horizontal bar, while the tail fin is located at the rear end of the horizontal bar. The wind vane indicates wind direction through the pole head and the tail fin.

[0008] Furthermore, a seated bearing is provided at the connection between the upright and the vertical shaft. The seat of the seated bearing has a first connecting hole. The vertical shaft is inserted into the inner ring of the seated bearing. A mounting base is provided at the top of the upright, and the mounting base has a second connecting hole. A bolt passes through both the first connecting hole of the seated bearing and the second connecting hole of the mounting base. A nut is threaded onto the first bolt. This structural arrangement ensures that the vertical shaft can rotate freely.

[0009] Furthermore, a rain shield is provided on the horizontal bar, the rain shield being inverted V-shaped, and the bearing with a mounting seat is located below the rain shield. The rain shield effectively prevents rainwater from directly hitting the bearing with a mounting seat.

[0010] Furthermore, the rotating rod is a T-shaped rod and includes a horizontal part and a vertical part. The vertical part of the rotating rod is fixedly sleeved on the rotating shaft, and the upright is fixedly installed on the horizontal part of the rotating rod.

[0011] Furthermore, a support plate is also provided on the fixing plate, and two parallel supports are provided on the support plate. The insertion rod slides through the two supports, and a spring is fitted on the insertion rod between the two supports. A stop pin is provided on the insertion rod, and the two ends of the spring are in contact with the stop pin and one of the supports, respectively. When the insertion rod is pulled outward, the spring is compressed and deformed; after being released, the spring returns to its deformation, pushing the insertion rod back into the positioning hole and preventing the insertion rod from coming out of the positioning hole.

[0012] Furthermore, the base is provided with a baffle, and the two ends of the baffle are respectively connected to a first fixing plate and a second fixing plate arranged opposite to each other. The baffle can ensure that the upright is laid down in a predetermined direction.

[0013] The beneficial effects of this utility model through the above technical solution are as follows:

[0014] The weather vane device provided by this utility model features an adjustment component between the upright and the base. When the upright needs to be lowered, pulling the insert rod outward compresses the spring, causing the insert rod to be pulled out of the positioning hole of the rotating rod. This allows the upright to slowly rotate clockwise around the pivot, thus lowering the upright and facilitating the replacement of the weather vane. After replacement, the upright is returned to a vertical position, and the insert rod is then inserted into the positioning hole. The cooperation between the insert rod and the positioning hole restricts the rotation of the rotating rod, thereby fixing the upright in a vertical position. At this time, the spring effectively prevents the insert rod from coming out of the positioning hole. In summary, this utility model allows for convenient replacement of the weather vane by lowering the upright, eliminating the need to climb to a high place for replacement, and is characterized by safety, labor-saving, and convenience.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1-6 As shown, this embodiment provides a wind vane device, including a base 1, a pole 2, a pole head 3, and a tail fin 4. An adjustment assembly is provided between the pole 2 and the base 1. The adjustment assembly includes a first fixed plate 5 and a second fixed plate 6 arranged opposite to each other. A rotating shaft 7 is rotatably arranged between the first fixed plate 5 and the second fixed plate 6. A rotating rod 8 is fixedly sleeved on the rotating shaft 7. A positioning hole 9 is provided on the rotating rod 8. An insert rod 10 that moves in the horizontal direction is provided on the first fixed plate 5. The insert rod 10 passes through the first fixed plate 5 and is inserted into the positioning hole 9.

[0025] The wind vane device provided by this utility model has an adjustment component between the upright pole 2 and the base 1. When the upright pole 2 needs to be lowered, the insert rod 10 is pulled outward to pull the insert rod 10 out of the positioning hole 9 of the rotating rod 8, so that the upright pole 2 rotates slowly clockwise around the rotating shaft 7, thereby lowering the upright pole 2 to facilitate the replacement of the wind vane. After the replacement is completed, the upright pole 2 is restored to the vertical state, and then the insert rod 10 is inserted into the positioning hole 9. At this time, the rotation of the rotating rod 8 is restricted by the cooperation between the insert rod 10 and the positioning hole 9, thereby keeping the upright pole 2 in a vertical state.

[0026] In this invention, a vertical shaft 11 is rotatably connected to the top of the upright pole 2. A horizontal rod 12 is mounted on the top of the vertical shaft 11. The pole head 3 is arrow-shaped and located at the front end of the horizontal rod 12. The tail fin 4 is located at the rear end of the horizontal rod 12. The wind vane indicates wind direction through the pole head 3 and the tail fin 4. When the wind blows, the tail fin 4, due to its large area, experiences a greater wind force. The thrust generated by the wind on the tail fin 4 causes the horizontal rod 12 to rotate around the vertical shaft 11 until the tail fin 4 is aligned with the wind direction, and the arrow-shaped pole head 3 points in the direction of the wind. At this point, the wind vane stabilizes at a specific angle, and the direction of the pole head 3 allows people to intuitively determine the current wind direction.

[0027] Please refer to this again. Figure 5 A bearing 13 with a mounting seat is provided at the connection between the upright 2 and the vertical shaft 11. The bearing 13 has a first connecting hole on its seat. The vertical shaft 11 is inserted into the inner ring of the bearing 13. A mounting base 14 is provided at the top of the upright 2. The mounting base 14 has a second connecting hole. A bolt 15 passes through both the first connecting hole of the bearing 13 and the second connecting hole of the mounting base 14. A nut is threaded onto the bolt 15. This structure ensures that the vertical shaft 11 can rotate freely.

[0028] In addition, a rain shield 16 is provided on the horizontal bar 12. The rain shield 16 is inverted V-shaped, and the bearing 13 with a seat is located below the rain shield 16. The inverted V-shaped rain shield 16 on the horizontal bar 12 can effectively prevent rainwater from directly hitting the bearing 13 with a seat.

[0029] Please refer to this again. Figure 4 The rotating rod 8 is a T-shaped rod and includes a horizontal part and a vertical part. The vertical part of the rotating rod 8 is fixedly sleeved on the rotating shaft 7, and the upright rod 2 is fixedly installed on the horizontal part of the rotating rod 8.

[0030] Please refer to this again. Figure 2 and Figure 3 The fixed plate 5 is further provided with a support plate 17, on which two parallel supports 18 are provided. The insertion rod 10 slides through the two supports 18. A spring 19 is fitted on the insertion rod 10 between the two supports 18. A stop pin 20 is provided on the insertion rod 10. The two ends of the spring 19 are in contact with the stop pin 20 and one of the supports 18, respectively. When the insertion rod 10 is pulled outward, the spring 19 is compressed and deformed; after being released, the spring 19 returns to its deformation, pushing the insertion rod 10 back into the positioning hole 9 and preventing the insertion rod 10 from coming out of the positioning hole 9.

[0031] It is worth mentioning that the base 1 is provided with a baffle 21, and the two ends of the baffle 21 are respectively connected to the oppositely arranged fixing plate 5 and fixing plate 6. The baffle 21 can ensure that the upright 2 is laid down in the predetermined direction, avoiding damage or danger caused by laying it down randomly.

[0032] The working principle of this utility model is as follows:

[0033] During installation, first fix the base 1 in a suitable position. The base 1 has mounting holes for fixing to the ground or other supporting structures. When it is necessary to lower the upright pole 2, pull the insert rod 10 outward to compress the spring 19, causing the insert rod 10 to be pulled out of the positioning hole 9 of the rotating rod 8. Please refer to the instructions again. Figure 6 The upright post 2 is slowly rotated clockwise around the pivot 7 to lay it down, making it easier to replace the direction marker. After replacement, the upright post 2 is restored to a vertical position, and then the insert rod 10 is inserted into the positioning hole 9. The cooperation between the insert rod 10 and the positioning hole 9 restricts the rotation of the pivot rod 8, thereby fixing the upright post 2 in a vertical position. At this time, under the action of the spring 19, the insert rod 10 is effectively prevented from coming out of the positioning hole 9.

[0034] In summary, this utility model allows for easy replacement of directional signs by lowering the pole, eliminating the need to climb to a high place for replacement, and is characterized by safety, labor-saving, and convenience.
