Description

Technical Field

[0001] The utility model belongs to the technical field of environmental monitoring, and in particular relates to an urban green space biomass measuring instrument. Background Art

[0002] As a vital component of urban ecosystems, urban green spaces play a crucial role in mitigating the urban heat island effect, improving air quality, and increasing biodiversity. Measuring and monitoring urban green space biomass is a crucial component of urban planning, environmental protection, and ecological management. Traditional biomass measurement methods typically rely on field surveys and laboratory analysis, which are not only time-consuming and labor-intensive but also have limitations when applied to large-scale monitoring.

[0003] With the development of remote sensing technology, multispectral and hyperspectral imaging techniques are increasingly being applied to ecological and environmental monitoring. Multispectral imaging can identify and classify different types of vegetation by capturing reflected light from objects at different wavelengths, while hyperspectral imaging can capture more detailed spectral information, providing more accurate data support for biomass measurement. However, how to effectively apply these imaging instruments to biomass measurement in urban green spaces remains a pressing technical challenge.

[0004] Existing imaging devices typically require fixed locations for data collection, a significant limitation for urban green space monitoring. Fixed-position imaging devices struggle to cover large areas of urban green space. Furthermore, at high altitudes, the imaging device's lens is susceptible to interference from external factors, such as dust and rain, which can reduce data collection accuracy. Furthermore, the operation and control of imaging devices must be more convenient and efficient to accommodate diverse monitoring needs. Utility Model Content

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide an urban green space biomass measuring instrument, which can not only improve the coverage and data accuracy of urban green space biomass measurement, but also significantly improve the convenience of operation and durability of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An urban green space biomass meter includes an imager body, a lens disposed at one end of the imager body, a base connected to one end of the lens, a through-hole formed through a side surface of the base, first positioning shafts fixedly connected to the side surface of the base, and the first positioning shafts are evenly spaced around the central axis of the base, and light shielding members are disposed on the side surface of the base, with the number of light shielding members corresponding to the number of first positioning shafts;

[0008] The light shielding member includes a plurality of light shielding plates sleeved on the first positioning shaft, wherein the plurality of light shielding plates are distributed in a circumferential shape to form a disk, and the side surfaces of the light shielding plates are rotatably connected to a driving arm;

[0009] The side of the light shielding member is rotatably connected to a linkage ring, and the side of the linkage ring is provided with a second positioning post corresponding to the driving arm, and the other end of the driving arm is sleeved on the second positioning post;

[0010] A protective ring is provided on the side of the linkage ring;

[0011] A motor seat is provided on the top of the base, and a motor for driving the linkage ring to rotate is installed on the motor seat.

[0012] Furthermore, a first connecting thread is provided on the outer side of one end of the lens, a connecting groove is provided on one side of the base, and a second connecting thread adapted to the first connecting thread is provided on the inner side wall of the connecting groove.

[0013] Furthermore, the output end of the motor base is sleeved with a driving wheel, and the driving wheel is in contact with the outer side surface of the linkage ring.

[0014] Furthermore, one end of the light shielding plate is penetrated by a positioning hole which is sleeved on the first positioning shaft, one end of the driving arm is penetrated by a second positioning hole which is sleeved on the second positioning column, the side of the light shielding plate is fixedly connected to the first positioning column, and the other end of the driving arm is sleeved on the first positioning column.

[0015] Furthermore, a second positioning shaft is fixedly connected to the side surface of the base, and the second positioning shaft is used to limit the rotation angle of the shading plate, and the number of the second positioning shaft is the same as that of the first positioning shaft.

[0016] Furthermore, a connecting seat is fixedly connected to the top of the imager body.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] First, by carrying the imager on a drone, it can be flexibly deployed at high altitudes to cover a wider range of urban green spaces. This design effectively solves the time-consuming and labor-intensive problems of traditional ground-based measurement methods and their limited coverage, making the collection of biomass data across large areas of urban green spaces more convenient and efficient.

[0019] Secondly, the imager itself is equipped with a self-expanding and self-closing visor. Driven by a motor and a linkage ring, the visor automatically expands when data acquisition is required, ensuring smooth image acquisition. When data acquisition is not required, the visor automatically closes, forming a circular disc that shields the lens and prevents foreign matter from accumulating during flight. This design ensures lens cleanliness and data acquisition accuracy, effectively protecting the imager's performance at high altitudes.

[0020] In addition, the design of the base and the shading member, including the combination of the first positioning axis, the second positioning axis, the positioning hole and the positioning column, enables the shading plate to be precisely positioned during the unfolding and closing process, ensuring the stability and reliability of the shading plate, and avoiding the problem of shading plate position displacement caused by external factors such as wind in a high-altitude environment.

[0021] Finally, the lens and base are connected via threads, allowing for easy assembly and disassembly of the lens, facilitating maintenance and replacement. Furthermore, the imager itself connects to the drone via a connector, simplifying installation and operation and improving data acquisition efficiency and accuracy. These design features not only enhance the device's ease of operation but also improve its durability and reliability, ensuring stable operation in diverse environments.

[0036] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0037] See Figure 1-7 A city green space biomass measuring instrument includes an imager body 1, a lens 11 is provided at one end of the imager body 1, one end of the lens 11 is connected to a base 2, a through hole 22 is opened on the side of the base 2, a first positioning axis 26 is fixedly connected to the side of the base 2, and the first positioning axis 26 is distributed at equal intervals around the central axis of the base 2, and a light shielding member 3 is provided on the side of the base 2, and the number of the light shielding members 3 corresponds to the number of the first positioning axes 26; the imager body 1 is a multispectral or hyperspectral imager, which is carried to high altitude by a drone to collect urban green space biomass data.

[0038] The shading member 3 includes a plurality of shading plates 31 mounted on the first positioning shaft 26. The plurality of shading plates 31 are distributed in a circular shape to form a disk. The side of the shading plate 31 is rotatably connected to a driving arm 32. When the motor 24 drives the driving wheel 25 to rotate, the driving wheel 25 fits against the outer side surface of the linkage ring 4. The linkage ring 4 rotates synchronously with the driving wheel 25. The second positioning column 41 pulls the shading plate 31 to expand around the first positioning shaft 26 through the driving arm 32, so that the lens 11 can smoothly collect image information.

[0039] The side of the light-shielding member 3 is rotatably connected to a linkage ring 4, and a second positioning column 41 corresponding to the driving arm 32 is provided on the side of the linkage ring 4, and the other end of the driving arm 32 is sleeved on the second positioning column 41; a protective ring 5 is provided on the side of the linkage ring 4, which is used to protect the lens 11 in the non-working state, prevent foreign matter from adhering to the lens, and ensure the cleanliness of the lens and the accuracy of data acquisition during flight.

[0040] A motor base 23 is provided on the top of the base 2, and a motor 24 for driving the linkage ring 4 to rotate is installed on the motor base 23; when data needs to be collected, the motor 24 is started, driving the driving wheel 25 to rotate, and then the light shielding plate 31 is unfolded through the linkage ring 4 and the driving arm 32; after the collection is completed, the motor 24 rotates in the opposite direction, and the driving wheel 25 drives the linkage ring 4 to rotate in the opposite direction, and the light shielding plate 31 is re-assembled into a disc shape to block the lens 11.

[0041] See Figure 1-3 A first connecting thread 111 is provided on the outer side of one end of the lens 11, a connecting groove 21 is provided on one side of the base 2, and a second connecting thread 211 is provided on the inner wall of the connecting groove 21 to match the first connecting thread 111; through the design of the connecting thread, the lens 11 can be easily installed and disassembled, ensuring the convenience of equipment maintenance and replacement.

[0042] See Figure 3 、 Figure 4 and Figure 7 The output end of the motor seat 23 is sleeved with a driving wheel 25, and the driving wheel 25 fits the outer side of the linkage ring 4; when the motor 24 is started, the driving wheel 25 rotates to drive the linkage ring 4 to rotate synchronously, thereby realizing the automatic expansion and closing of the sunshade 31.

[0043] See Figure 5-6 One end of the light shielding plate 31 is penetrated by a positioning hole 311 which is sleeved on the first positioning shaft 26, and one end of the driving arm 32 is penetrated by a second positioning hole 321 which is sleeved on the second positioning column 41. The side of the light shielding plate 31 is fixedly connected to the first positioning column 312, and the other end of the driving arm 32 is sleeved on the first positioning column 312; through the design of the positioning holes and the positioning columns, the light shielding plate 31 can be accurately positioned and operate stably, ensuring the normal operation of the imager in different environments.

[0044] See Figure 5 A second positioning axis 27 is fixedly connected to the side of the base 2, and the second positioning axis 27 is used to limit the rotation angle of the sunshade 31, and the number of the second positioning axis 27 is the same as the first positioning axis 26; the design of the positioning axis ensures the accuracy of the position of the sunshade 31 during the expansion and closing process, and prevents the sunshade from being offset by wind in a high-altitude environment.

[0045] See Figure 3 The top of the imager body 1 is fixedly connected with a connecting seat 12; through the connecting seat 12, the imager body 1 can be easily installed on a drone, realizing flexible high-altitude deployment and data collection, greatly improving the coverage and data accuracy of urban green space biomass measurement.

[0046] The working principle of this utility model is:

[0047] The imager body 1 is a multispectral or hyperspectral imager. When in use, the connection base 12 needs to be connected to a drone, and the imager body 1 is taken to a high altitude by the drone, so that the imager body 1 can collect biomass data of urban green spaces.

[0048] When it is necessary to collect data on green space biomass through the imager body 1, the motor 24 drives the driving wheel 25 to rotate, and the driving wheel 25 is in contact with the outer side of the linkage ring 4. When the driving wheel 25 rotates, the linkage ring 4 rotates synchronously therewith. When the linkage ring 4 rotates, the second positioning column 41 pulls the driving arm 32, and by pulling the driving arm 32, the light shielding plate 31 is driven to expand around the first positioning axis 26, thereby enabling the lens 11 to smoothly collect image information.

[0049] When it is not necessary to collect image information, the driving wheel 25 only needs to rotate in the opposite direction, which will make the shading plates 31 approach each other and form a disc shape to block the lens 11. In this way, foreign matter can be prevented from adhering to the lens 11 during flight.

[0050] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
