Description

Technical Field

[0001] This utility model relates to the field of laser wind measurement radar technology, and in particular to a miniature ground-based laser wind measurement radar. Background Technology

[0002] Laser wind radar, as a core device for atmospheric wind field monitoring, is widely used in meteorological observation, aviation safety, wind power generation, and other fields. Traditional ground-based laser wind radar emits a laser beam and receives backscattered signals from atmospheric aerosols or molecules, using the Doppler frequency shift principle to invert wind speed and direction information. However, existing ground-based laser wind radars generally suffer from large size and excessive weight (usually over 50 kg), severely limiting their flexibility in field deployment, temporary observation station construction, and application in complex terrain environments.

[0003] In recent years, with the miniaturization of lasers, optical devices, and electronic modules, compact design of laser wind radar has become an industry trend. However, one of the core challenges in the miniaturization process is thermal management: traditional large-scale equipment relies on ample internal space and natural convection for heat dissipation, but with compaction, the internal space is drastically reduced, making it difficult to directly reuse existing ventilation structures. Insufficient heat dissipation will lead to temperature drift of optical components, performance degradation or even failure of electronic devices, directly affecting measurement accuracy and equipment reliability. In existing technologies, some miniaturization attempts have attempted to achieve this by simply compressing the component layout or adding heat sinks in certain areas, but these often lack systematic airflow planning, resulting in uneven airflow distribution and low heat dissipation efficiency, failing to meet the requirements for long-term stable operation.

[0004] Therefore, a miniature ground-based laser wind-measuring radar is urgently needed. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a miniature ground-based laser wind measuring radar, aiming to solve the problem of internal heat dissipation difficulties caused by miniaturization in existing ground-based laser wind measuring radars.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a miniature ground-based laser wind radar, comprising a ground base and a compact housing disposed on the upper end of the ground base, characterized in that: a first wind duct module and a second wind duct module are symmetrically arranged on the upper end of the ground base; an acousto-optic modulator and an optical transceiver are integrated on the side of the first wind duct module away from the second wind duct module, and a data acquisition card is integrated on the side of the second wind duct module away from the first wind duct module; an industrial control computer motherboard and communication components are integrated on the side of the second wind duct module away from the first wind duct module, and a power supply component is integrated on the side of the second wind duct module; a lens frame is mounted on the upper end between the first wind duct module and the second wind duct module, and a laser radar lens assembly is installed on the lens frame; the laser radar lens assembly is compactly integrated between the first wind duct module and the second wind duct module; the height of the first wind duct module and the second wind duct module is 2 / 3 of the internal height of the compact housing.

[0007] Based on the above, the beneficial effect of a miniature ground-based laser wind measuring radar is that it solves the problem of internal heat dissipation difficulties caused by miniaturization in existing ground-based laser wind measuring radars; this is mainly reflected in:

[0008] 1. This utility model reduces the weight of traditional ground-based laser wind radar from 50kg to 16kg through a compact design, while optimizing the internal structure layout to make it easier to carry, install and deploy, especially suitable for mobile field observation and temporary site construction;

[0009] 2. This utility model adopts a symmetrical layout of the first air duct module and the second air duct module, and combines it with the bottom air intake-exhaust fan system to form an optimized airflow path, ensuring efficient heat dissipation of key components such as the lidar lens assembly, acousto-optic modulator, and industrial control computer motherboard, and avoiding optical performance degradation or electronic component failure due to temperature rise.

[0010] 3. The functional components (such as the acoustic-optical modulator, acquisition card, power module, etc.) are reasonably distributed around the air duct module to ensure heat dissipation efficiency, reduce signal interference, and improve the stability and measurement accuracy of the system operation.

[0011] Furthermore, a temperature sensor and a gyroscope are configured in the middle of the foundation base, and the temperature sensor and gyroscope are located between the first air duct module and the second air duct module.

[0012] Based on the above, the temperature sensor and gyroscope are integrated between the first air duct module and the second air duct module. This not only utilizes the airflow in the air duct to achieve efficient heat dissipation, but also ensures comprehensive monitoring coverage through the central position, while reducing the space occupied by other components.

[0013] Furthermore, fan mounting ports are symmetrically arranged at both ends of the bottom of the foundation base. Each fan mounting port has an air inlet and an air outlet. The air inlet is equipped with several air intake fans, and the air outlet is equipped with several air outlet fans. The two fan mounting ports correspond to the first air duct module and the second air duct module, respectively. The air inlet corresponds to the air inlet of the first air duct module and the second air duct module, and the air outlet corresponds to the air outlet of the first air duct module and the second air duct module. Dust baffles are installed around both air inlets.

[0014] Based on the above, the symmetrically arranged intake and exhaust fans within the first and second air duct modules have the beneficial effect of forming directional airflow circulation, effectively improving heat dissipation efficiency, and ensuring stable operating temperature of core components within a compact space. The two fan mounting ports, corresponding to the air inlets and outlets of the two air duct modules respectively, have the beneficial effect of forming independent heat dissipation channels, avoiding cross-interference of airflows, and optimizing the heat dissipation path. The dust baffles surrounding the air inlet section have the beneficial effect of blocking external dust and particles from entering the equipment, extending the equipment's service life while ensuring heat dissipation efficiency.

[0015] Furthermore, the lidar lens assembly includes a wedge mirror and a support gear fixed to the periphery of the wedge mirror. A lens drive motor is provided on one side of the lens holder, and the output end of the lens drive motor drives the support gear to rotate via a belt.

[0016] Based on the above, the beneficial effect of the lens drive motor is that it can switch the light spot emission angle by driving the wedge mirror to rotate.

[0017] Furthermore, a lens mounting port is provided at the upper center of the compact housing, and a lens is disposed on the lens mounting port.

[0018] Based on the above, the modular lens design supports quick replacement, which has the following benefits: individual maintenance is possible when the surface becomes contaminated or worn, significantly reducing equipment maintenance costs.

[0019] Furthermore, a windshield wiper is provided at the upper end of the compact housing. The windshield wiper is located behind the lens mounting port, and the output end of the windshield wiper moves in a fan shape on the lens surface.

[0020] Based on the above, the beneficial effects of windshield wipers are to remove pollutants such as rainwater, snow, and dust, and to ensure that the accuracy of laser ranging is not affected by environmental factors.

[0021] Furthermore, a signal antenna is also provided at the upper end of the compact housing.

[0022] Based on the above, the beneficial effects of the signal antenna are to enable real-time wireless transmission of wind measurement data, get rid of the limitations of traditional wired connections, and improve the deployment flexibility of the equipment in complex terrain.

[0023] Furthermore, handles are symmetrically arranged on both sides of the foundation base.

[0024] Based on the above, the beneficial effect of the handle is to provide an ergonomic grip point for lightweight equipment weighing 16kg, significantly improve the ease of handling and installation of the equipment, and meet the needs of rapid deployment in the field.

[0025] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

A lens frame 5 is mounted on the upper end between the first wind duct module 3 and the second wind duct module 4. A laser radar lens assembly 6 is installed on the lens frame 5. The laser radar lens assembly 6 is compactly integrated between the first wind duct module 3 and the second wind duct module 4. The height of the first wind duct module 3 and the second wind duct module 4 is 2 / 3 of the internal height of the compact housing 2.

[0033] A temperature sensor 7 and a gyroscope 8 are arranged in the middle of the foundation base 1, and the temperature sensor 7 and the gyroscope 8 are located between the first air duct module 3 and the second air duct module 4.

[0034] The foundation base 1 has symmetrical fan mounting ports 11 at both ends. Each fan mounting port 11 has an air inlet 111 and an air outlet 112. The air inlet 111 is equipped with a plurality of air intake fans 1111, and the air outlet 112 is equipped with a plurality of air outlet fans 1121. The two fan mounting ports 11 correspond to the first air duct module 3 and the second air duct module 4, respectively. The air inlet 111 corresponds to the air inlet of the first air duct module 3 and the second air duct module 4, and the air outlet 112 corresponds to the air outlet of the first air duct module 3 and the second air duct module 4. Dust baffles 1112 are installed around both air inlets 111.

[0035] The lidar lens assembly 6 includes a wedge mirror 61 and a support gear 62 fixed around the wedge mirror 61. A lens drive motor 51 is provided on one side of the lens holder 5. The output end of the lens drive motor 51 drives the support gear 62 to rotate via a belt.

[0036] The compact housing 2 has a lens mounting port 21 at the upper middle part, and a lens 211 is disposed on the lens mounting port 21.

[0037] The upper end of the compact housing 2 is also provided with a windshield wiper 22, which is located behind the lens mounting port 21. The output end of the windshield wiper 22 moves in a fan shape on the surface of the lens 211.

[0038] A signal antenna 23 is also provided at the upper end of the compact housing 2.

[0039] Handles 12 are symmetrically arranged on both sides of the foundation base 1.

[0040] In summary, the specific implementation of this utility model is as follows: When the equipment is working, the foundation base 1 provides stable support for the overall structure.

[0042] The heat dissipation system achieves active air cooling through the fan mounting port 11 at the bottom of the foundation base 1. The air intake fan 1111 of the air intake section 111 draws in external air, which is filtered by the dust baffle 1112 and then enters the air duct module. After carrying away the internal heat, it is discharged by the air outlet fan 1121 of the air outlet section 112, forming an efficient heat dissipation cycle. The handles 12 on both sides facilitate the handling and installation of the equipment, further improving the ease of use.

[0043] The entire system, through its compact design and modular layout, achieves lightweight design and efficient heat dissipation while ensuring measurement accuracy, meeting the stable operation requirements in various environments.
