Description

Technical Field

[0001] This utility model relates to the field of wind speed detection technology, and more specifically, to a foldable and retractable wind speed detection device. Background Technology

[0002] Common wind speed detection devices can only detect wind speed but lack the function of folding and storing. In practical applications, they rely on the ambient wind to blow the wind cup, which in turn drives the anemometer to rotate via the rod. The actual wind speed value is calculated by the rotation speed. However, when the device is transported or encounters harsh environments, the rod and wind cup are in a horizontal position. When subjected to external forces, the rod may break or the wind cup may be damaged, ultimately resulting in a reduced service life.

[0003] In summary, to extend the lifespan of the device, it is necessary to address the issue of the inability to fold and store the rod, enabling the rod and wind cup to be folded and stored under specific conditions, thereby preventing damage from external forces. Utility Model Content

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5 A foldable and retractable wind speed detection device includes a mounting cylinder 1, an anemometer body 11 at the upper end of the mounting cylinder 1, three storage slots 12 on the surface of the anemometer body 11, a first connecting shaft 13 installed inside the storage slots 12, a connecting strip 14 installed on the outer side of the first connecting shaft 13, a drive rod 15 installed on the surface of the connecting strip 14, a wind cup 16 installed at the end of the drive rod 15 away from the connecting strip 14, an arc-shaped spring sheet 17 installed inside the storage slots 12, a support mechanism on the anemometer body 11, and an auxiliary rotation mechanism on the mounting cylinder 1 and the anemometer body 11.

[0023] It should be noted that the mounting cylinder 1 serves as the basic support structure, on which the anemometer body 11 is located, responsible for the core wind speed detection function. It typically includes counting and signal conversion components. Three storage slots 12 are distributed around the anemometer body 11 to accommodate the folded drive rod 15 and wind cup 16. The first connecting shaft 13 is the pivot point for the rotation of the connecting bar 14, drive rod 15, and wind cup 16, allowing them to rotate inward or outward. The arc-shaped spring plate 17 is installed in the storage slot 12, and its function is to provide a restriction on the position of the wind cup 16, preventing the drive rod 15 and wind cup 16 from detaching from the storage slot 12 when storage is required. The support mechanism is used to provide additional rigid support when the wind cup 16 is deployed, preventing the drive rod 15 from rotating back into the storage slot 12 due to wind force or its own weight.

[0024] It is worth noting that the key innovation of this design lies in its foldable storage. Through the combination of the storage slot 12, the first connecting shaft 13 and the arc-shaped spring plate 17, the drive rod 15 and the wind cup 16 can be folded up from the horizontally unfolded working state, which significantly reduces the lateral size of the device, greatly facilitates transportation and storage, and protects the fragile drive rod 15 and wind cup 16 from damage by external impact in harsh weather or non-working state, thereby effectively extending the service life of the device. The support mechanism ensures the structural stability of the device in the unfolded working state.

[0025] Refer to the instruction manual appendix Figures 1 to 5 The support end of the support mechanism is connected to the drive rod 15. The support mechanism is used to support the drive rod 15. The support mechanism includes a rotating component and a plugging component. The connecting end of the rotating component is connected to the plugging component. The rotating component is used to control the rotation angle of the plugging component. The plugging end of the plugging component is connected to the drive rod 15. The plugging component is used to support the drive rod 15.

[0026] It should be noted that the core function of the support mechanism is to provide stable support for the drive rod 15 when it is unfolded, ensuring that it remains stable under wind force and will not rotate back into the storage tank 12 due to wind force or its own weight. The mechanism consists of two parts: the rotating component is responsible for adjusting the flexibility of the support angle, allowing the support structure itself to adapt to the folding and unfolding movements of the drive rod 15; the plug-in component provides a direct and rigid connection point, effectively transmitting the support force to the drive rod 15 and locking its working position.

[0027] Refer to the instruction manual appendix Figure 4 The rotating assembly includes a second connecting shaft 211 installed inside the storage slot 12 and a connecting block 212 installed outside the second connecting shaft 211.

[0028] It should be noted that the second connecting shaft 211 is fixed inside the storage slot 12 and serves as the core fulcrum of the rotating component. The connecting block 212 is rotatably connected to the second connecting shaft 211 and can rotate around the second connecting shaft 211. The connecting block 212 is the output end of the rotating component, which transmits the rotational degree of freedom to the subsequent support rod 221.

[0029] Refer to the instruction manual appendix Figures 4 to 5 The plug-in assembly includes a support rod 221 mounted on the surface of the connecting block 212 and a plug-in groove 222 formed on the surface of the drive rod 15. The end of the support rod 221 away from the connecting block 212 is inserted into the interior of the plug-in groove 222.

[0030] It should be noted that one end of the support rod 221 is fixed to the connecting block 212, and the other end is designed to be inserted into the corresponding insertion slot 222 on the drive rod 15. When the drive rod 15 is extended to the working position, the end of the support rod 221 is inserted into the insertion slot 222, forming a physical limit and rigid connection. This insertion method effectively applies the supporting force of the support rod 221 directly to the drive rod 15, preventing it from moving downward or inward.

[0031] Refer to the instruction manual appendix Figures 1 to 3 The auxiliary rotation mechanism is used to assist the anemometer body 11 in rotation. The auxiliary rotation mechanism includes an anti-stagnation component and an anti-shaking component. The anti-stagnation component is used to prevent the anemometer body 11 from stopping due to excessive friction with the mounting cylinder 1. The anti-shaking component is used to limit the position of the anti-stagnation component.

[0032] It should be noted that the core function of this mechanism is to ensure that the anemometer body 11 rotates with minimal resistance and smooth operation when driven by the wind cup 16. The anti-stagnation component mainly solves the problems of difficult rotation start-up and excessive frictional resistance. Its goal is to reduce the frictional resistance between the anemometer body 11 and the mounting cylinder 1, so that it can start smoothly and maintain rotation even in weak winds, avoiding stagnation due to excessive static friction. The anti-sway component mainly solves the problem of radial runout or swaying during rotation. By constraining the axis, it limits the excessive radial displacement or swaying of the anemometer body 11 during rotation, ensuring the stability of the rotation center, thereby improving measurement accuracy and signal stability.

[0033] It is worth noting that the auxiliary rotation mechanism adopts a dual-component design for anti-stagnation and anti-shaking, which are optimized for different problems in the rotation process. This combined design can comprehensively improve the smoothness, stability and measurement accuracy of the anemometer's rotation. The anti-shaking component limits the position of the anti-stagnation component, ensuring that the axial and radial clearances of the entire rotation system are effectively controlled while maintaining low friction.

[0034] Refer to the instruction manual appendix Figure 2 The anti-stagnation component includes a rotating shaft 311 installed at the lower end of the anemometer body 11, a collar 312 installed on the outside of the rotating shaft 311, and a plurality of balls 313 installed on the outside of the collar 312. The collar 312 is rotatably connected to the mounting cylinder 1.

[0035] It should be noted that the rotating shaft 311 is fixed to the lower end of the anemometer body 11 as its core shaft for rotation. The collar 312 is sleeved on the outside of the rotating shaft 311, but it is not fixed. Instead, it can rotate relative to the rotating shaft 311 or rotate together with the rotating shaft 311. Multiple balls 313 are embedded on the outer circumference of the collar 312, and the balls 313 roll between the contact surface of the collar 312 and the mounting cylinder 1.

[0036] Refer to the instruction manual appendix Figure 2The anti-sway assembly includes multiple fixing rods 322 installed inside the mounting cylinder 1 and a limiting ring 321 installed on one end of the multiple fixing rods 322 near the rotating shaft 311. The limiting ring 321 is rotatably connected to the rotating shaft 311.

[0037] It should be noted that one end of the multiple fixing rods 322 is fixed to the inner wall of the mounting cylinder 1, and the other end together supports and fixes a limiting ring 321. The limiting ring 321 surrounds the outer side of the rotating shaft 311. The inner ring of the limiting ring 321 forms a rotational fit with the outer surface of the rotating shaft 311, allowing the rotating shaft 311 to rotate smoothly within the limiting ring 321, but at the same time restricting the large-scale radial movement of the rotating shaft 311.

[0038] Refer to the instruction manual appendix Figure 2 The mounting cylinder 1 is provided with a fixing component, which is used to install on the fixing frame. The fixing component includes a flange 411 installed at the lower end of the mounting cylinder 1, a fixing circular plate 412 installed at the lower end of the flange 411, and a mounting plate 413 installed on the outside of the fixing circular plate 412.

[0039] It should be noted that the fixing component is installed at the bottom of the mounting cylinder 1, the flange 411 provides a connection interface with the lower end of the mounting cylinder 1, the fixing circular plate 412 is connected below the flange 411 to form a large mounting base surface, and the mounting plate 413 is installed on the outer edge of the fixing circular plate 412. The mounting plate 413 usually has bolt holes for using bolts and other fasteners to firmly install the entire device onto the fixing frame.

[0040] Working principle: In the deployed working state, when the device needs to measure wind speed, the drive rod 15, along with the wind cup 16, is rotated outward from the storage slot 12 to the horizontal working position. During this process, the drive rod 15 rotates around the first connecting shaft 13 and compresses the arc-shaped spring plate 17 through the wind cup 16. When the drive rod 15 is fully deployed, the connecting block 212 is rotated simultaneously, causing it to rotate around the second connecting shaft 211, which drives the support rod 221 to move until the end of the support rod 221 away from the connecting block 212 is accurately inserted into the pre-set insertion slot 222 on the surface of the drive rod 15. At this time, the rigid support arm formed by the connecting block 212 and the support rod 221 is locked, providing stable support for the drive rod 15 in the cantilever state and preventing it from being affected by wind. Under its own weight, the anemometer may fold back or sway. During wind speed detection, the ambient wind force acts on the wind cup 16, pushing the wind cup 16 and driving the drive rod 15 to rotate. The rotation of the drive rod 15 is transmitted to the anemometer body 11 through the connecting strip 14, driving the entire anemometer body 11 to rotate around its vertical axis. The rotating shaft 311 at the lower end of the anemometer body 11 rotates inside the mounting cylinder 1 accordingly. The anti-stagnation component plays a role here. The collar 312 rotates with the rotating shaft 311, and the multiple balls 313 on its outer side roll between the collar 312 and the inner wall of the mounting cylinder 1, converting sliding friction into rolling friction, significantly reducing rotational resistance, ensuring that the anemometer body 11 can start smoothly and rotate at a uniform speed even in weak winds, and avoiding measurement errors caused by friction stagnation. Simultaneously, the anti-sway components work together. The limiting ring 321 is fixed inside the mounting cylinder 1 by multiple fixing rods 322 and forms a rotational engagement with the rotating shaft 311. The limiting ring 321 constrains the radial displacement of the rotating shaft 311, effectively suppressing the radial runout or sway that may occur during the rotation of the anemometer body 11, ensuring the stability of the rotation center, thereby improving the accuracy and reliability of the wind speed conversion signal. Normally, the internal counter of the anemometer body 11 records the rotation speed per unit time and converts it into a wind speed signal output. When encountering severe weather or needing transportation or long-term storage, a storage operation is performed. First, the drive rod 15 is pushed away from the support rod 221 until the support rod 221 disengages from the insertion slot 222, releasing the constraint on the drive rod. The support rod 15 is locked in place, and then the support rod 221 is rotated to enter the storage slot 12. The wind cup 16 and drive rod 15 are then pushed further into the storage slot 12. The drive rod 15 rotates and folds around the first connecting shaft 13 towards the anemometer body 11. During this folding process, the wind cup 16 will again compress the arc-shaped spring sheet 17 until the drive rod 15 and wind cup 16 are fully inside the storage slot 12. At this point, the arc-shaped spring sheet 17 returns to its original position due to its elasticity. This effectively blocks the wind cup 16, preventing accidental ejection of the wind cup 16 and drive rod 15 due to vibration or movement. After both the drive rod 15 and wind cup 16 are folded in this manner, the horizontal protrusion of the entire device is greatly reduced.This significantly reduces the risk of the drive rod 15 breaking or the wind cup 16 being damaged due to external impacts during transportation, storage, or in harsh environments.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
