[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0031] Example 1

[0032] Reference Figure 1 - Figure 6 This is the first embodiment of the present invention, which provides a cleaning device for a laser anemometer, including a main component 100, a movable component 200, and a cleaning component 300. When the sea breeze blows, the movable component 200 rotates and moves up and down, driving the cleaning component 300 to drive away lingering birds and simultaneously blow away dust from the laser mirror of the laser anemometer. This solves the problem that birds lingering or dust accumulating on the laser mirror, which would affect the measurement accuracy of the laser anemometer if not cleaned for a long time.

[0033] Specifically, the main component 100 includes a fixed base 101 and a laser anemometer 102, wherein the fixed base 101 is fitted onto the laser emitting surface of the laser anemometer 102.

[0034] Furthermore, the bottom end of the movable component 200 is inserted into the interior of the fixed base 101. The movable component 200 includes a rotating component 201 and a lifting component 202, wherein the rotating component 201 and the lifting component 202 are movably connected.

[0035] Preferably, the rotating component 201 is driven by wind power, and the generated power is sufficient to drive the internal structure to rotate. When there is no wind, the rotating component 201 is driven to rotate by an internal motor.

[0036] Furthermore, the cleaning component 300 is movably connected to the movable component 200. The cleaning component 300 includes a bird deterrent component 301 and a dust removal component 302, wherein the bird deterrent component 301 is located away from the dust removal component 302, and both are movably connected to the rotating component 201.

[0037] In summary, the sea breeze provides power to the rotating component 201. When birds linger, the rotating component 201 rotates and moves up and down under the action of the lifting component 202. This causes the bird deterrent component 301 to swing back and forth and move up and down, creating irregular glare interference for the birds, thus driving them away. This solves the problem that bird droppings can affect the measurement accuracy of the laser anemometer. When dust falls on the laser mirror, the rotation and up-and-down movement of the rotating component 201 drives the dust removal component 302 to rotate and blow air, achieving the effect of blowing away dust from the mirror and removing it. This solves the problem that dust accumulation can affect laser emission and thus measurement accuracy.

[0038] Example 2

[0039] Reference Figure 1 - Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the fixed base 101 includes a lifting cavity 101a, a receiving cavity 101b, and a swing slot 101c. The lifting cavity 101a is a cavity inside the fixed base 101. The receiving cavity 101b is arranged around the fixed base 101. The swing slot 101c is arc-shaped and is opened through the side wall of the receiving cavity 101b.

[0041] Preferably, in this embodiment, the accommodating cavity 101b is provided in four locations, respectively located at the four corners of the fixed base 101.

[0042] Furthermore, the laser anemometer 102 includes a body 102a and a laser mirror 102b, wherein the body 102a is cuboid and the laser mirror 102b is located on the side of the body 102a facing the sky.

[0043] Preferably, when in use, the laser beam emitted by the laser mirror 102b will not be blocked by other structures in the device.

[0044] Furthermore, the rotating component 201 includes an impeller 201a, a connecting rod 201b, and a rotating disk 201c, wherein the impeller 201a is a hollowed-out hemispherical shape and is connected to one end of the connecting rod 201b, and the rotating disk 201c is connected to the other end of the connecting rod 201b.

[0045] Preferably, refer to Figure 1 In this embodiment, the impeller 201a and the connecting rod 201b are arranged as a set, with a total of four sets, and are evenly connected around the rotating disk 201c, and are not blocked by other parts of the device when rotating.

[0046] Furthermore, the lifting component 202 includes a lifting spring 202a and a lifting ring 202b. The lifting spring 202a is disposed in the lifting cavity 101a. One end of the lifting spring 202a abuts against the rotating component 201, and the other end abuts against the fixed base 101. The lifting ring 202b is cylindrical, and its side near the wind vane is integrally fixedly connected to the fixed base 101.

[0047] Preferably, when the sea breeze is too strong and causes the impeller 201a to rotate too fast, the lifting spring 202a is used to buffer the speed and force of the rotating part 201 moving up and down, thereby reducing the wear of the device. When the impeller 201a rotates at a slower speed, the resistance caused by the lifting spring 202a will not affect the up and down displacement of the rotating part 201.

[0048] Furthermore, the lifting ring 202b is fitted onto the inner ring of the rotating disk 201c, and includes a limiting groove 202b-1, which is continuously formed on the outer ring sidewall of the lifting ring 202b.

[0049] Preferably, the limiting groove 202b-1 is always engaged with the cylindrical protrusion on the inner ring sidewall of the rotating disk 201c. When the limiting groove 202b-1 is laid flat, it forms a sinusoidal curve. When the rotating disk 201c rotates, the cylindrical protrusion on its inner ring is limited in the limiting groove 202b-1 and undergoes regular up-and-down displacement during rotation, which in turn drives the rotating disk 201c to move up and down.

[0050] Furthermore, referring to Figure 4 The rotating disk 201c is annular and includes a limiting protrusion 201c-1, an upper clamping plate 201c-2, a lower clamping plate 201c-3, and a rotating gear 201c-4. The limiting protrusion 201c-1 is fixedly installed on the inner ring side wall of the annular rotating disk 201c and is always embedded in the limiting groove 202b-1. The upper clamping plate 201c-2 and the lower clamping plate 201c-3 are integrally installed on the outer side wall of the rotating disk 201c, and a gap is left between the upper and lower clamping plates. The rotating gear 201c-4 is provided on the side wall of the rotating disk 201c in the gap.

[0051] Furthermore, the bird deterrent component 301 includes a sector gear 301a, a support rod 301b, a swing screw 301c, a reflector 301d, and a torsion spring 301e. The sector gear 301a is movably meshed with the rotating gear rail 201c-4, and the wheel body of the sector gear 301a is limited in the gap between the upper clamping plate 201c-2 and the lower clamping plate 201c-3. The support rod 301b and the swing screw 301c penetrate vertically through the middle of the sector gear 301a. Both ends of the support rod 301b are fixed to the inner wall of the fixed base 101. One end of the swing screw 301c abuts against the inner wall of the accommodating cavity 101b, and the other end is fixedly connected to the reflector 301d. The swing screw 301c is limited in the accommodating cavity 101b and will not be displaced. The torsion spring 301e is sleeved on the rod body of the support rod 301b.

[0052] Preferably, when the rotating disk 201c rotates, the rotating toothed track 201c-4 intermittently meshes with the sector gear 301a, driving the sector gear 301a to rotate along the support rod 301b. When the rotating toothed track 201c-4 disengages from the sector gear 301a, the sector gear 301a returns to its initial position under the action of the torsion spring 301e. The above action is repeated when the next rotating toothed track 201c-4 arrives and meshes with it.

[0053] Furthermore, the side wall of the sector gear 301a is provided with a support through hole 301a-1 and a swing screw hole 301a-2. The support rod 301b is connected to the sector gear 301a through the support through hole 301a-1, and the swing screw 301c is connected to the sector gear 301a through the swing screw hole 301a-2, and is in mutual fit with the internal thread of the swing screw hole 301a-2.

[0054] Preferably, when the rotating disk 201c moves up and down, the upper clamping plate 201c-2 and the lower clamping plate 201c-3 clamp the sector gear 301a and drive it to move up and down. At this time, the swing screw hole 301a-2 drives the swing screw 301c to rotate, thereby driving the reflector 301d to rotate.

[0055] Preferably, refer to Figure 3 The end of the oscillating screw 301c that contacts the receiving cavity 101b is equipped with a ball bearing to reduce friction.

[0056] In summary, when the wind blows towards the impeller 201a, it drives the rotating disk 201c to rotate via the connecting rod 201b. At this time, the rotating disk 201c rotates. Since the limiting protrusion 201c-1 on the inner wall of the rotating disk 201c is always embedded in the limiting groove 202b-1 which is a closed sine curve, the rotating disk 201c will also move up and down at the same time as it rotates. When the rotating disk 201c rotates, the discontinuously set rotating gear 201c-4 intermittently meshes with and disengages from the sector gear 301a, causing the sector gear 301a to repeatedly oscillate around the support rod 301b under the action of the torsion spring 301e, and drive the oscillating screw 301c connected to it to oscillate, and finally drive the reflector 301d to oscillate.

[0057] When the rotating disk 201c moves up and down, the upper clamping plate 201c-2 and the lower clamping plate 201c-3 clamp the sector gear 301a and drive it to move up and down. At this time, the swing screw hole 301a-2 drives the swing screw 301c to rotate, thereby driving the reflector 301d to rotate.

[0058] By swinging and rotating the reflector 301d back and forth, it creates glare for birds, thus driving them away and solving the problem that birds lingering or even droppings can affect the measurement accuracy of the laser anemometer.

[0059] Example 3

[0060] Reference Figure 6 - Figure 7 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0061] Furthermore, the dust removal component 302 includes a cleaning ring 302a, a scraper 302b, and a push rod 302c. One end of the push rod 302c is inserted inside the cleaning ring 302a, and the other end is fixedly connected to the scraper 302b. One end of the cleaning ring 302a is connected to one end of the rotating ring 201c. The brush surface of the scraper 302b is always in contact with the laser emitting surface of the machine body 102a.

[0062] Furthermore, the cleaning ring 302a includes a pump chamber 302a-1, a nozzle 302a-2, and an airbag 302a-3. The pump chamber 302a-1 is a cylindrical cavity, and the airbag 302a-3 is placed in the pump chamber 302a-1. One end of the push rod 302c is placed in the pump chamber 302a-1 and is always in contact with the pressing surface of the airbag 302a-3. The nozzle 302a-2 has an air passage inside, and one end of the nozzle 302a-2 is fixedly connected to the inner wall of the cleaning ring 302a. The air passage of the nozzle 302a-2 is connected to the pump chamber 302a-1. The air outlet of the airbag 302a-3 is aligned with the air passage of the nozzle 302a-2 and inserted into the connection.

[0063] Preferably, refer to Figure 6 When the cleaning ring 302a moves upward, the airbag 302a-3 loses its squeezing force and returns to its relaxed state, acting as a spring and driving the push rod 302c to extend outward, so that the scraper 302b always abuts against the body 102a. The mounting position of the fixed base 101 and the body 102a is provided with a gap, which leads to the outside. The dust swept by the scraper 302b will be discharged from the gap when rotating.

[0064] Preferably, in this embodiment, except for the cleaning ring 302a, the other dust removal components 302 are provided in four places and are evenly arranged, wherein the air jet holes of the nozzles 302a-2 face the laser mirror surface 102b and do not obstruct it.

[0065] In summary, based on embodiment 2, when the rotating disk 201c rotates, the cleaning ring 302a fixedly connected to it rotates synchronously, and drives the push rod 302c with one end set inside it to rotate. At this time, the scraper 302b fixed to the push rod 302c rotates and scrapes the non-laser mirror area of ​​the machine body 102a, and discharges the dust from the bottom of the fixed base 101 and the gap between the machine body 102a.

[0066] When the rotating disk 201c moves up and down, it causes the cleaning ring 302a, which is fixedly connected to it, to move downward. This causes the push rod 302c, with one end inside the ring, to compress the airbag 302a-3. At this time, the airbag 302a-3 inflates and is ejected through the internal air passage of the nozzle 302a-2, thus blowing away the dust from the laser mirror 102b. Afterward, the scraper 302b sweeps away the blown-away dust. This achieves the cleaning effect on both the laser mirror 102b and the machine body 102a, effectively solving the problem that dust accumulation can obstruct the laser mirror and affect measurements.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
