Description

Technical Field

[0001] This utility model relates to the field of meteorological equipment technology, and in particular to a wind vane structure. Background Technology

[0002] To ensure proper orientation and wind speed at oil and gas well sites, wind vanes are installed as required, indicating wind direction and providing wind speed references. Existing wind vane structures include a base tube, a wind vane bag, and a wind mast. The wind vane bag is installed at the top of the wind mast, with the bottom of the wind mast inserted into the base tube. Due to exposure to wind and sun, the lifespan of the wind vane bag is generally one to two years. When the wind vane bag is damaged, it needs to be replaced. Replacement is typically done by inserting and removing the wind mast or by using ladders or lifting platforms for high-altitude work. However, the small gap between the base tube and the wind mast allows rainwater and dust to enter, making insertion and removal difficult and time-consuming. Furthermore, using ladders or lifting platforms for high-altitude work poses safety hazards. Utility Model Content

[0003] This utility model provides a wind vane structure that facilitates the replacement of wind vane bags, saves time and effort, eliminates the need for high-altitude operations, and ensures high safety.

[0004] In a first aspect, embodiments of this utility model provide a weather vane structure, comprising:

[0005] Lower tube;

[0006] The upper tube is located at the upper end of the lower tube;

[0007] A first connecting component is located on one side of the lower tube. The first connecting component is connected to the lower tube and is rotatably connected to the upper tube.

[0008] A second connecting assembly is located on the side of the lower tube away from the first connecting assembly, and the second connecting assembly is rotatably connected to both the upper tube and the lower tube; and

[0009] A snap-fit ​​is provided on the second connecting component;

[0010] The second connecting component is configured to be parallel to the lower tube in the indicated state, and the snap-fit ​​is configured to snap into the lower tube in the indicated state so that the upper tube is coaxial with the lower tube; the second connecting component is configured to be inclined to the lower tube in the replacement state, and the snap-fit ​​is configured to release the lower tube in the replacement state so that the upper tube rotates downward.

[0011] In one embodiment, the first connecting assembly includes a first connecting rod, one end of which is fixedly connected to the upper end of the lower tube, and the other end of which is hinged to the lower end of the upper tube.

[0012] In one embodiment, the second connection component includes:

[0013] A second connecting rod, the upper end of which is hinged to the lower end of the upper tube; and

[0014] The third connecting rod has one end hinged to the upper end of the lower tube, and the other end hinged to the middle of the second connecting rod.

[0015] The second and third connecting rods are configured to be parallel to the lower tube in the indicated state and inclined to the lower tube in the replacement state.

[0016] In one embodiment, the weather vane structure further includes a fixing rod, one end of which is fixedly connected to the end of the second connecting rod away from the upper tube, and the other end of which is fixedly connected to the buckle.

[0017] In one embodiment, the weather vane structure further includes a fixing rod, which passes through the end of the second connecting rod away from the upper tube and is threadedly connected to the second connecting rod. One end of the fixing rod is rotatably connected to the buckle.

[0018] In one embodiment, the buckle is provided with a notch for insertion of the lower tube.

[0019] In one embodiment, the lower tube includes a support tube segment and an installation tube segment disposed at the upper end of the support tube segment, wherein the first connecting component and the second connecting component are rotatably connected to the installation tube segment.

[0020] In one embodiment, the included angle between the first connecting component and the second connecting component is 180°.

[0021] In one embodiment, the weathervane structure further includes a weathervane bag disposed at the upper end of the upper side tube.

[0022] In one embodiment, the length of the lower tube is greater than 50 cm.

[0023] Compared with the prior art, the advantages of this utility model embodiment are that by setting a first connecting component, a second connecting component, and a buckle, the upper tube is driven to move, changing the positional relationship between the upper and lower tubes. This allows switching between an indicating state and a replacement state. In the indicating state, the upper and lower tubes are coaxially arranged to ensure the height of the wind vane structure, enabling the wind vane to indicate wind direction and provide wind speed reference. In the replacement state, the second connecting component is driven to rotate upward, causing the upper tube to rotate downward, lowering the height of the upper tube 20 and allowing it to be laid flat for easy replacement of the wind vane. Therefore, compared to replacing the wind vane by inserting and removing the wind rod or by working at height, the wind vane structure provided by this utility model only requires rotating the second connecting component to drive the upper tube to rotate downward, lowering the height of the upper tube and laying it flat for replacement of the wind vane. There is no need to insert and remove the wind rod, making the entire replacement process convenient, easy, time-saving, labor-saving, and safe as it eliminates the need for working at height.

[0038] The present invention will be further described below with reference to the accompanying drawings.

[0039] The existing wind vane structure includes a base tube, a wind vane bag, and a wind mast. The wind vane bag is installed at the top of the wind mast, and the bottom of the wind mast is inserted into the base tube. Due to wind and sun exposure, the lifespan of the wind vane bag is generally one to two years. When the wind vane bag is damaged, it needs to be replaced. Replacement is usually done by inserting and removing the wind mast or by using a ladder or lifting platform for high-altitude work. However, the gap between the base tube and the wind mast is small, and rainwater and dust can enter the gap, making it difficult to insert and remove the wind mast. Replacement is time-consuming and laborious, while using ladders, lifting platforms, and other high-altitude work methods poses safety hazards.

[0040] Example 1

[0041] like Figure 1 , Figure 2 , Figure 5 As shown, to solve the above-mentioned technical problems, this utility model embodiment provides a wind vane structure, including a lower tube 10, an upper tube 20, a first connecting component 30, a second connecting component 40, and a buckle 50; the upper tube 20 is located at the upper end of the lower tube 10; the first connecting component 30 is located on one side of the lower tube 10, the first connecting component 30 is connected to the lower tube 10, and the first connecting component 30 is rotatably connected to the upper tube 20; the second connecting component 40 is located on the lower tube 10 away from the first connecting component 30. On one side, the second connecting component 40 is rotatably connected to the upper tube 20 and the lower tube 10 respectively; the buckle 50 is disposed on the second connecting component 40; wherein, the second connecting component 40 is configured to be parallel to the lower tube 10 in the indicated state, and the buckle 50 is configured to be engaged with the lower tube 10 in the indicated state so that the upper tube 20 and the lower tube 10 are coaxial; the second connecting component 40 is configured to be inclined to the lower tube 10 in the replacement state, and the buckle 50 is configured to be released from the lower tube 10 in the replacement state so that the upper tube 20 rotates downward.

[0042] As can be seen from the above, by setting the first connecting component 30, the second connecting component 40, and the buckle 50, the upper tube 20 is driven to move, changing the positional relationship between the upper tube 20 and the lower tube 10. This allows switching between the indicating state and the replacement state. In the indicating state, the upper tube 20 and the lower tube 10 are coaxially arranged to ensure the height of the wind vane structure, enabling the wind vane to indicate wind direction and provide wind speed reference. In the replacement state, the second connecting component 40 is driven to rotate upward, causing the upper tube 20 to rotate downward, lowering its height and allowing it to be laid flat for easy replacement of the wind vane. Therefore, compared to replacing the wind vane by inserting and removing the wind rod or by working at height, the wind vane structure provided by this utility model only requires rotating the second connecting component 40 to drive the upper tube 20 to rotate downward, lowering its height and laying it flat for replacement of the wind vane. There is no need to insert and remove the wind rod, making the entire replacement process convenient, easy, time-saving, labor-saving, and safe as it does not require working at height.

[0043] It should be noted that the buckle 50 is an elastic plastic buckle with a certain degree of deformation capability, and the inner diameter of the buckle 50 is equal to the outer diameter of the lower tube 10.

The upper tube 20 and the lower tube 10 are rotatably connected; a buckle 50 is disposed on the second connecting component 40; wherein, the second connecting component 40 is configured to be parallel to the lower tube 10 in the indicated state, and the buckle 50 is configured to be engaged with the lower tube 10 in the indicated state, so that the upper tube 20 and the lower tube 10 are coaxial; the second connecting component 40 is configured to be inclined to the lower tube 10 in the replacement state, and the buckle 50 is configured to be released from the lower tube 10 in the replacement state, so that the upper tube 20 rotates downward.

[0046] As can be seen from the above, by setting the first connecting component 30, the second connecting component 40, and the buckle 50, the upper tube 20 is driven to move, changing the positional relationship between the upper tube 20 and the lower tube 10. This allows switching between the indicating state and the replacement state. In the indicating state, the upper tube 20 and the lower tube 10 are coaxially arranged to ensure the height of the wind vane structure, enabling the wind vane to indicate wind direction and provide wind speed reference. In the replacement state, the second connecting component 40 is driven to rotate upward, causing the upper tube 20 to rotate downward, lowering its height and allowing it to be laid flat for easy replacement of the wind vane. Therefore, compared to replacing the wind vane by inserting and removing the wind rod or by working at height, the wind vane structure provided by this utility model only requires rotating the second connecting component 40 to drive the upper tube 20 to rotate downward, lowering its height and laying it flat for replacement of the wind vane. There is no need to insert and remove the wind rod, making the entire replacement process convenient, easy, time-saving, labor-saving, and safe as it does not require working at height.

[0047] It should be noted that the buckle 50 is an elastic plastic buckle with a certain degree of deformation capability, and the inner diameter of the buckle 50 is equal to the outer diameter of the lower tube 10.

[0048] like Figure 1 , Figure 2 As shown, in some embodiments, the first connecting component 30 includes a first connecting rod 310, one end of which is fixedly connected to the upper end of the lower tube 10, and the other end of which is hinged to the lower end of the upper tube 20.

[0049] By setting the first connecting component 30 and the second connecting component 40 to cooperate, a structural basis is provided for realizing the rotation of the upper tube 20.

[0050] It should be noted that, as Figure 1 As shown, the lower end of the upper tube 20 is provided with a first sub-head 210, one end of the first connecting rod 310 is fixedly connected to the lower tube 10, and the other end of the first connecting rod 310 is hinged to the end of the first sub-head 210 and the end of the first connecting rod 310.

[0051] like Figure 1 , Figure 2 , Figure 5 As shown, in some embodiments, the second connecting assembly 40 includes a second connecting rod 410 and a third connecting rod 420; the upper end of the second connecting rod 410 is hinged to the lower end of the upper tube 20; one end of the third connecting rod 420 is hinged to the upper end of the lower tube 10, and the other end of the third connecting rod 420 is hinged to the middle part of the second connecting rod 410; wherein, the second connecting rod 410 and the third connecting rod 420 are configured to be parallel to the lower tube 10 in the indicated state and inclined to the lower tube 10 in the replacement state.

[0052] A linkage mechanism is formed by the second connecting rod 410 and the third connecting rod 420. The linkage mechanism cooperates with the first connecting rod 310 to drive the upper tube 20 to rotate, thereby switching between the indicating state and the replacement state. In the indicating state, the second connecting rod 410 and the third connecting rod 420 rotate to be parallel to the lower tube 10, and the buckle 50 is engaged with the lower tube 10. The upper tube 20 is coaxial with the lower tube 10 to ensure the height of the wind vane structure, so that the wind vane bag can indicate the wind direction and provide wind speed reference. In the replacement state, the buckle 50 is separated from the lower tube 10, the second connecting rod 410 and the third connecting rod 420 rotate to be inclined to the lower tube 10, and the upper tube 20 rotates downward so that the height of the upper tube 20 is lowered and it can be laid flat to facilitate the replacement of the wind vane bag.

[0053] It should be noted that the lower end of the upper tube 20 is provided with a second female head 220, the second connecting rod 410 is provided with a first female head 4101 and a second female head, and the upper end of the lower tube 10 is provided with a third female head 130; wherein, the second female head 220 is hinged to the first female head 4101, and the third female head 130 is hinged to the second female head.

[0054] It should also be noted that the third connecting rod 420 is made of high-strength plastic material, including but not limited to polyetheretherketone (PEEK) and polyimide (PI).

[0055] like Figure 1 As shown, in some embodiments, the weather vane structure further includes a fixing rod 60, one end of which is fixedly connected to the end of the second connecting rod 410 away from the upper tube 20, and the other end of which is fixedly connected to the buckle 50.

[0056] It should be noted that the connection methods between the fixing rod 60 and the second connecting rod 410 and the buckle 50 include, but are not limited to, welding.

[0057] In some embodiments, the weather vane structure further includes a fixing rod 60, which passes through the end of the second connecting rod 410 away from the upper tube 20 and is threadedly connected to the second connecting rod 410. One end of the fixing rod 60 is rotatably connected to the buckle 50.

[0058] By setting the fixing rod 60 to be threadedly connected to the second connecting rod 410, the position of the buckle 50 can be adjusted by rotating the fixing rod 60. When the second connecting rod 410 and the third connecting rod 420 are parallel to the lower tube 10, the fixing rod 60 can be rotated to change the distance between the buckle 50 and the lower tube 10, so that the buckle 50 can be locked on the outer wall of the lower tube 10.

[0059] like Figure 2 , Figure 5 , Figure 6As shown, in some embodiments, the snap 50 is provided with a notch 510 for the lower tube 10 to be inserted.

[0060] It should be noted that the buckle 50 is shaped to match the lower tube 10, and the central angle of the buckle 50 is greater than 180°.

[0061] like Figure 1 , Figure 2 As shown, in some embodiments, the lower tube 10 includes a support tube section 110 and an installation tube section 120 disposed at the upper end of the support tube section 110, wherein the first connecting component 30 and the second connecting component 40 are rotatably connected to the installation tube section 120.

[0062] It should be noted that, as Figure 1 As shown, the installation pipe section 120 is connected to the support pipe section 110 by means of welding or bonding, and the upper end face of the installation pipe section 120 is flush with the upper end face of the support pipe section 110; the third sub-head is provided on the installation pipe section 120.

[0063] In some embodiments, the included angle between the first connecting component 30 and the second connecting component 40 is 180°.

[0064] By setting the included angle between the first connecting component 30 and the second connecting component 40 to 180°, the normal movement of the first connecting component 30, the second connecting component 40, and the upper tube 20 is ensured, and interference or jamming that could prevent normal movement is avoided.

[0065] In some embodiments, the weather vane structure further includes a weather vane bag disposed at the upper end of the upper side tube 20.

[0066] It should be noted that the connection method between the wind direction bag and the upper side pipe 20 is existing technology, and will not be described in detail in this application.

[0067] In some embodiments, the length of the lower tube 10 is greater than 50 cm.

[0068] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, during use, the lower pipe 10 is vertically fixed to the ground with anchor bolts, with the lower pipe 10 extending 50cm above the ground. At this time, the upper pipe 20 is in a flat position. The user installs the wind vane on the end of the upper pipe 20 away from the lower pipe 10, and then rotates the upper pipe 20 upwards. The upper pipe 20 rotates around the first connecting rod 310 until the upper pipe 20 and the lower pipe 10 are coaxial. Then, the second connecting rod 410 is rotated downwards until the second connecting rod 410 and the third connecting rod 420 are parallel to the lower pipe 10. The buckle 50 is then fastened to the outer wall of the lower pipe 10. At this time, the wind vane structure is in the indicating state.

[0069] Rotate the second connecting rod 410 upwards to move it away from the lower tube 10, thus separating the buckle 50 from the lower tube 10. Then, continue to rotate the second connecting rod 410 upwards to rotate the upper tube 20 downwards, thereby lowering the height of the upper tube 20 and flattening it. At this point, the wind vane structure is in the replacement state, and the user can replace the wind vane bag.

[0070] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
