Description

Technical Field

[0001] This utility model relates to the field of lidar technology, specifically to a lens for a lidar wind measurement radar. Background Technology

[0002] In the field of laser wind measurement radar, the lens is a key component, and its structural design significantly impacts the equipment's performance and adaptability. Traditional laser wind measurement radar lenses typically consist of a lens barrel, a fiber optic headstock, and fiber optic connectors attached to the headstock. The lens barrel is of fixed length, resulting in a relatively fixed overall structure. This fixed structure reveals significant limitations in practical applications: a lens barrel with a specific structure can only accommodate a fixed type of fiber optic connector. During actual use, the fiber optic connector may need to be replaced for various reasons, such as replacement after damage, performance upgrades due to technological advancements, or the need for different specifications of connectors due to specific experimental or production processes. However, because the traditional lens barrel has a fixed length, even a slight difference in the length of the fiber optic connector renders the new connector incompatible with the existing structure. This often necessitates replacing the entire lens assembly when a fiber optic connector needs to be replaced, leading to unnecessary resource waste and significantly increasing equipment purchase costs. This is detrimental to the long-term stable operation and cost control of laser wind measurement radar equipment. Utility Model Content

[0003] In view of the shortcomings in the background technology, this utility model provides a lens for a laser wind measuring radar.

[0004] The technical solution adopted by this utility model is: a lens for a laser wind measuring radar, including a lens barrel and an optical fiber head base, wherein the lens barrel includes a main lens barrel, an optical element one, an optical element two and a conical lens barrel;

[0005] The optical element one and optical element two are installed inside the main lens barrel, and an internal thread is provided on the inner wall of one end of the through hole of the main lens barrel;

[0006] The conical lens tube is equipped with the aforementioned fiber optic head mount at one end, and has a connecting cylinder adapted to the through hole at the other end. The outer wall of the connecting cylinder is provided with an external thread that is threaded to the aforementioned internal thread.

[0007] Furthermore, the main lens barrel includes a coarse diameter section and a fine diameter section, and the outer wall of the coarse diameter section is provided with an external thread.

[0008] Furthermore, the diameter of the narrow section is equal to the maximum outer diameter of the conical lens barrel.

[0009] Furthermore, the second optical element is a concave mirror, and a mounting cavity for mounting a lens holder is provided inside the through hole at the bottom of the internal thread. The second optical element is mounted on the lens holder by a lens retainer.

[0010] Furthermore, the optical element one is a convex mirror, and a mounting cavity two for mounting the optical element one is provided on the end of the main mirror tube away from the conical mirror tube. The optical element one is mounted in the mounting cavity two by means of a lens retainer two.

[0011] Furthermore, it also includes a lens mounting base, which has multiple internal threaded holes that are connected to the external thread, and a mounting plate with fixing holes on the side of the lens mounting base.

[0012] Furthermore, it also includes a locking ring, which is threadedly connected to the aforementioned external thread.

[0013] Furthermore, the outer wall of the locking ring is provided with a plurality of recessed holes at intervals.

[0014] The beneficial effects of this utility model are:

[0015] 1. Reduced Usage Costs: When the fiber optic head needs to be replaced, it is no longer necessary to replace the entire lens assembly as with traditional lenses. In the past, even slight differences in the length of the fiber optic head required replacing the entire lens, resulting in a large number of old lenses being idle and wasted. This patented design allows the lens barrel length to be adjusted simply by rotating the main lens barrel and the conical lens barrel to fit the new fiber optic head, avoiding unnecessary equipment purchases and greatly reducing resource waste and equipment acquisition costs.

[0016] 2. Improved compatibility. Whether it's replacing a product of the same type but a different batch due to fiber optic head damage, replacing a new model fiber optic head to meet performance upgrade requirements, or adapting special specification fiber optic heads in different experimental or production processes, different fiber optic heads can be adapted by rotating the main tube and the conical tube to adjust the tube length. This broadens the application range of laser wind radar in various scenarios and improves the equipment's versatility.

[0017] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] This invention provides a lens for a laser wind-measuring radar.

[0025] In this embodiment, refer to Figure 1-3 The lens of the laser wind measuring radar includes a lens barrel 1 and an optical fiber head 2. The lens barrel includes a main lens barrel 3, an optical element 4, an optical element 5, and a conical lens barrel 6.

[0026] The optical element one and optical element two are installed inside the main lens barrel, and an internal thread 8 is provided on the inner wall of one end of the through hole 7 of the main lens barrel.

[0027] The conical lens tube 6 has the aforementioned fiber optic head 2 installed on one end, and a connecting tube 9 adapted to the through hole on the other end. The outer wall of the connecting tube 9 is provided with an external thread 10 that is threaded to the aforementioned internal thread.

[0028] In the above technical solution, by designing the lens barrel as a combined structure comprising a main lens barrel, optical element one, optical element two, a locking ring, and a conical lens barrel, with the main lens barrel and the conical lens barrel connected by threads, the adjustable length of the lens barrel is achieved. This allows the lens to adapt to fiber optic heads of different lengths, avoiding the need to replace the entire lens assembly due to differences in fiber optic head lengths, reducing resource waste and equipment purchase expenses, while improving the lens's versatility in different scenarios. Optical element one and optical element two are installed inside the main lens barrel and can perform specific optical processing such as refraction and reflection of light, meeting the precise light control requirements of laser wind radar.

[0029] Among them, such as Figure 3 As shown, external thread one and internal thread one are not drawn; the label 8 / 11 indicates the position of external thread two.

[0030] Specifically, the main lens barrel includes a coarse diameter section 11 and a fine diameter section 12, and the outer wall of the coarse diameter section 11 is provided with an external thread 13.

[0031] In this embodiment, the main lens barrel is designed to include a coarse-diameter section and a fine-diameter section, and the outer wall of the coarse-diameter section is provided with an external thread II, which facilitates the connection of the lens with other components (such as a lens mount). By engaging the external thread II with the internal threaded holes of other components, a stable installation of the lens can be achieved, while also facilitating flexible installation and adjustment of the lens in different devices or installation scenarios.

[0032] Specifically, the diameter of the narrow section is equal to the maximum outer diameter of the conical lens barrel.

[0033] In this embodiment, the diameter of the narrow section is equal to the maximum outer diameter of the conical lens barrel, which makes the overall appearance of the main lens barrel and the conical lens barrel more coordinated and smooth after connection, reducing problems such as airflow interference that may be caused by excessive diameter difference.

[0034] Specifically, the second optical element is a concave mirror, and a mounting cavity 15 for mounting the lens holder 14 is provided inside the through hole at the bottom of the internal thread. The second optical element is mounted on the lens holder 14 through a lens retainer 16.

[0035] In this embodiment, the second optical element is a concave mirror. The second optical element is installed through the first lens retainer, which is convenient to install and remove, has a stable and reliable connection, and is low in cost.

[0036] Specifically, the optical element one is a convex mirror, and a mounting cavity two 17 for mounting the optical element one is provided on the end of the main mirror tube away from the conical mirror tube. The optical element one is mounted in the mounting cavity two through a lens retainer two 18.

[0037] In this embodiment, optical element one is a convex mirror, and optical element one is installed through lens retainer two, which is convenient to install and disassemble, has a stable and reliable connection, and is low in cost.

[0038] Specifically, it also includes a lens mounting base 19, which has multiple internal threaded holes 20 that are connected to the external thread, and a mounting plate 21 with fixing holes 22 on the side of the lens mounting base.

[0039] In this embodiment, the lens mount connects to the external threaded section of the main lens barrel via multiple internal threaded holes (e.g., ...). Figure 2 As shown (external thread 2 is not drawn; label 13 indicates the position of external thread 2), the connection ensures a stable lens mounting, and the lens mounting angle can be adjusted by rotation. The lens mount has a mounting plate and fixing holes on its side, facilitating the fixing of the entire lens mount to other equipment or support structures, improving the flexibility and adaptability of lens mounting, and meeting the needs of different installation scenarios.

[0040] Specifically, it also includes a locking ring 23, which is threadedly connected to the aforementioned external thread.

[0041] In this embodiment, the locking ring is threaded onto the outer wall of the connecting cylinder to stabilize the positioning between the main lens barrel and the conical lens barrel, thereby improving the stability of their connection.

[0042] Specifically, the outer wall of the locking ring is provided with a plurality of recessed holes 24 at intervals.

[0043] In this embodiment, multiple recessed holes are spaced apart on the outer wall of the locking ring, providing operators with better points of force application. When it is necessary to tighten or loosen the locking ring, the operator can use appropriate tools (such as a wrench with protrusions) to insert into the recessed holes, making the operation more convenient and labor-saving, and improving the convenience and efficiency of adjusting the barrel length during installation and maintenance.

[0044] Please note to all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
