Abstract
Description
Technical Field
[0001] This invention relates to the field of botanical research technology, specifically to a retractable plant height measuring device. Background Technology
[0002] How to maintain biodiversity and achieve harmonious development between humans, nature, and society during urbanization has attracted widespread attention from scholars both domestically and internationally. Exploring the mechanisms by which urbanization affects biodiversity and interspecific relationships is crucial for building vibrant, healthy, and stable urban ecosystems and maintaining sustainable urban development, and is a hot topic in global ecological research. Traditional parks and green spaces, primarily designed for safety, aesthetics, and recreation, mainly employ tree and grass planting methods. This results in a limited variety of plant community composition and structure, providing limited resources for food sources and habitats for birds and insects. Furthermore, overly frequent maintenance and management can negatively impact birdlife.
[0003] These near-natural parks and green spaces have the following characteristics: they exhibit "near-natural" features in terms of species composition, community structure, and management methods; they are located in core urban areas, surrounded by numerous buildings, and disturbed by high-density pedestrian traffic; and their area is less than 5 hectares. It is generally believed that biodiversity gradually increases with the increase of green space area within a certain range. However, whether the "near-natural" characteristics can significantly improve biodiversity, including that of birds, in small, highly disturbed green spaces requires further investigation.
[0004] However, in practical applications, accurate measurement of plant height is fundamental for assessing plant growth, selecting varieties, and optimizing planting layouts in fields such as botanical research, horticultural management, and agricultural planting. Traditional measurement methods, such as using rulers or tape measures, are not only time-consuming and labor-intensive, but also difficult to operate and have limited accuracy when dealing with large trees or dense plant communities. Summary of the Invention
[0005] The purpose of this invention is to provide a retractable plant height measuring device to address the issues raised in the background art, such as the fundamental need for accurately measuring plant height in botanical research, horticultural management, and agricultural planting to assess plant growth, select varieties, and optimize planting layouts. Traditional measurement methods, such as using rulers or tape measures, are not only time-consuming and labor-intensive, but also present significant operational difficulties and limited measurement accuracy when dealing with large trees or dense plant communities.
[0006] To achieve the above objectives, the present invention provides the following technical solution: including a mobile vehicle body and a measuring base;
[0007] The front end of the mobile vehicle is rotatably connected to a traction rod via a pin shaft. The four corners of the mobile vehicle are fixedly installed with a first electric telescopic rod. The lower telescopic part of the first electric telescopic rod is fixedly installed with a support foot for supporting the ground. The front end of the mobile vehicle is supported and fixedly installed with a first drive motor. The lower drive shaft of the first drive motor is fixedly installed with a transmission gear. The side end of the transmission gear is meshed with a transmission gear ring. The outer end of the transmission gear ring is fixedly installed with a rotating base.
[0008] The measuring base has a first contraction groove rotatably connected to its top rear side via a pin. A second electric telescopic rod is rotatably connected to the top rear side of the measuring base via a pin. A third electric telescopic rod is fixedly installed on the lower inner wall of the first contraction groove. The second contraction groove is fixedly installed on the upper telescopic portion of the third electric telescopic rod. An L-shaped support platform is rotatably connected to the top rear side of the first contraction groove via a pin. A fourth electric telescopic rod is rotatably connected to the top rear side of the first contraction groove via a pin. A recognition camera for identifying the position of the plant top and the ground is fixedly installed on the upper rear side of the L-shaped support platform. A measuring plate is fixedly installed on the lower end of the L-shaped support platform. An L-shaped measuring frame is fixedly installed on the front end of the measuring plate. A horizontal laser rangefinder and a vertical laser rangefinder are fixedly installed on the rear end and lower end of the L-shaped measuring frame, respectively. A positioning module is fixedly installed on the upper end of the measuring plate.
[0009] Preferably, the traction rod has a connection hole at its front end.
[0010] Preferably, a power control cabinet and an operating panel are fixedly installed at the rear end of the mobile vehicle body, and a mobile power supply is fixedly installed inside the power control cabinet.
[0011] Preferably, there are four first electric telescopic rods, which are symmetrically distributed at the four corners of the mobile vehicle body, and the rotating base is rotatably connected to the front end of the mobile vehicle body via a rotating shaft.
[0012] Preferably, the measuring base is fixedly installed on the upper end of the rotating base, the upper end of the second electric telescopic rod is inclined backward, and the telescopic part of the upper end of the second electric telescopic rod is rotatably connected to the lower end of the first contraction groove by a pin.
[0013] Preferably, the lower end of the second shrinkage groove is movably connected to the inner wall of the first shrinkage groove, and the upper telescopic part of the fourth electric telescopic rod is rotatably connected to the lower end of the L-shaped support platform by a pin.
[0014] Preferably, the positioning module has a positioning sensor, a gyroscope, and an accelerometer fixedly installed inside.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. When the mobile vehicle is towed to the location where the plant height needs to be measured, the present invention uses a horizontal laser rangefinder and a vertical laser rangefinder to measure the horizontal distance between the measuring plate and the plant and the vertical height from the ground, respectively. When the measuring plate is aligned with the plant height to be measured, the plant height can be measured by measuring the vertical height from the plate to the ground. At the same time, the position of the top of the plant and the ground is identified by a recognition camera, which further improves the accuracy of the measurement. Simultaneously, the second electric telescopic rod is activated to extend and retract. When the second electric telescopic rod extends and retracts, it causes the upper end of the first contraction groove to swing up and down. When the upper end of the first contraction groove swings up and down, it simultaneously causes the L-shaped measuring frame to swing up and down to adjust the measurement height. When the L-shaped measuring frame swings up and down to adjust the measurement height, the fourth electric telescopic rod is activated to extend and retract. When the fourth electric telescopic rod extends and retracts, it causes the L-shaped measuring frame to swing up and down to adjust the measurement angle, so that the L-shaped measuring frame maintains the measurement posture. This allows for the measurement of plant height while facilitating the measurement of plants of different heights.
[0017] 2. Furthermore, when the third electric telescopic rod extends or retracts, it causes the second contraction groove to move linearly along the inner wall of the first contraction groove. Simultaneously, as the second contraction groove moves linearly along the inner wall of the first contraction groove, it also synchronously extends or retracts the entire L-shaped measuring frame. At the same time, the first drive motor is activated, driving the transmission gear to rotate. When the transmission gear rotates, the force generated by the meshing of the transmission gear and the transmission gear ring causes the rotating base to rotate horizontally. When the rotating base rotates horizontally, it causes the measuring base frame to rotate horizontally. When the measuring base frame rotates horizontally, it synchronously causes the L-shaped measuring frame to rotate horizontally to adjust the measuring position. This allows for simultaneous height measurement of the plant while facilitating telescopic and horizontal adjustment of the measuring position. Attached Figure Description

[0023] 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.
[0024] Please see Figure 1-4 The present invention provides a technical solution comprising a mobile vehicle body 1 and a measuring base frame 2;
[0025] A towing rod 101 is rotatably connected to the front end of the mobile vehicle body 1 via a pin. A connection hole 102 is provided at the front end of the towing rod 101, allowing it to be connected to an external towing device for towing. A power control cabinet 103 and an operating panel 104 are fixedly installed at the rear end of the mobile vehicle body 1. A mobile power supply is fixedly installed inside the power control cabinet 103. Four first electric telescopic rods 105 are fixedly installed through the four corners of the mobile vehicle body 1. The first electric telescopic rod 105 is symmetrically distributed at the four corners of the mobile vehicle body 1. The lower telescopic part of the first electric telescopic rod 105 is fixedly installed with support feet 106 for supporting the ground. The front end of the mobile vehicle body 1 is fixedly supported and installed with a first drive motor 107. The lower drive shaft of the first drive motor 107 is fixedly installed with a transmission gear 108. The side end of the transmission gear 108 is meshed with a transmission gear ring 109. The outer end of the transmission gear ring 109 is fixedly installed with a rotating base 110, and the rotating base 110 is rotatably connected to the front end of the mobile vehicle body 1 through a rotating shaft.
[0026] The measuring base 2 is fixedly installed on the upper end of the rotating base 110. A first contraction groove 201 is rotatably connected to the rear side of the top of the measuring base 2 via a pin. A second electric telescopic rod 202 is rotatably connected to the rear side of the top of the measuring base 2 via a pin, and the upper end of the second electric telescopic rod 202 is tilted backward. The telescopic portion of the upper end of the second electric telescopic rod 202 is rotatably connected to the lower end of the first contraction groove 201 via a pin. A third electric telescopic rod 203 is fixedly installed on the inner wall of the lower end of the first contraction groove 201. A second contraction groove 204 is fixedly installed on the telescopic portion of the upper end of the third electric telescopic rod 203, and the lower end of the second contraction groove 204 is movably connected to the inner wall of the first contraction groove 201, allowing the first contraction groove 201 to linearly limit the movement of the second contraction groove 204. An L-shaped support platform 205 is rotatably connected to the rear side of the top of the first contraction groove 201 via a pin. A fourth electric telescopic rod 206 is rotatably connected to the rear side of the upper end of the first contraction groove 201 via a pin. The upper telescopic part of the fourth electric telescopic pole 206 is rotatably connected to the lower end of the L-shaped support platform 205 via a pin. A recognition camera 207 for identifying the position of the top of the plant and the ground is fixedly installed on the rear side of the upper end of the L-shaped support platform 205. A measuring plate 208 is fixedly installed on the lower end of the L-shaped support platform 205. An L-shaped measuring frame 209 is fixedly installed on the front end of the measuring plate 208. A horizontal laser rangefinder 210 and a vertical laser rangefinder 211 are fixedly installed on the rear end and lower end of the L-shaped measuring frame 209, respectively, so that the horizontal distance between the measuring plate 208 and the plant and the vertical height of the ground can be measured by the horizontal laser rangefinder 210 and the vertical laser rangefinder 211, respectively. A positioning module 212 is fixedly installed on the upper end of the measuring plate 208, and a positioning sensor, a gyroscope and an accelerometer are fixedly installed inside the positioning module 212, so that the measurement location of the measuring plate 208 is recorded by the positioning sensor, and the attitude angle of the measuring plate 208 is measured by the gyroscope and the accelerometer.
[0027] In use, the mobile vehicle 1 is connected to the external traction device through the connection hole 102 and the traction rod 101. When the mobile vehicle 1 is connected to the external traction device, the external traction device pulls the mobile vehicle 1 to the location where the plant height needs to be measured. When the mobile vehicle 1 is pulled to the location where the plant height needs to be measured, the first electric telescopic rod 105 is extended downward by control. When the first electric telescopic rod 105 extends downward, it will drive the support foot 106 to move downward in a straight line to support the ground. When the support foot 106 supports the ground, it will keep the mobile vehicle 1 stable, so that the mobile vehicle 1 can be easily pulled and moved while maintaining stability.
[0028] When the mobile vehicle 1 is towed to the location where the plant height needs to be measured, the horizontal distance between the measuring plate 208 and the plant and the vertical height from the ground are measured by the horizontal laser rangefinder 210 and the vertical laser rangefinder 211, respectively. When the measuring plate 208 is aligned with the plant height to be measured, the plant height can be measured by measuring the vertical height of the plate 208 from the ground. At the same time, the position of the top of the plant relative to the ground is identified by the recognition camera 207, further improving the accuracy of the measurement. Simultaneously, the second electric telescopic rod 202 is extended and retracted by controlling its activation. When the 02 is extended or retracted, it will cause the upper end of the first contraction groove 201 to swing up and down. When the upper end of the first contraction groove 201 swings up and down, it will simultaneously cause the L-shaped measuring frame 209 to swing up and down to adjust the measuring height. When the L-shaped measuring frame 209 swings up and down to adjust the measuring height, the fourth electric telescopic rod 206 is activated by control to extend or retract. When the fourth electric telescopic rod 206 extends or retracts, it will cause the L-shaped measuring frame 209 to swing up and down to adjust the measuring angle, so that the L-shaped measuring frame 209 maintains the measuring posture, thereby realizing the height measurement of plants and facilitating the measurement of plants of different heights.
[0029] The third electric telescopic rod 203 is extended and retracted by controlling its activation. When the third electric telescopic rod 203 extends and retracts, it drives the second contraction groove 204 to move linearly along the inner wall of the first contraction groove 201. When the second contraction groove 204 moves linearly along the inner wall of the first contraction groove 201, it simultaneously drives the L-shaped measuring frame 209 to extend and retract as a whole. At the same time, the first drive motor 107 is activated by controlling its activation. When the first drive motor 107 is activated, it drives the transmission gear 108 to rotate. When the transmission gear 108 rotates, the force generated by the meshing connection between the transmission gear 108 and the transmission gear ring 109 drives the rotating base 110 to rotate horizontally. When the rotating base 110 rotates horizontally, it drives the measuring base frame 2 to rotate horizontally. When the measuring base frame 2 rotates horizontally, it simultaneously drives the L-shaped measuring frame 209 to rotate horizontally to adjust the measuring position. This allows for the measurement of plant height while facilitating extension, retraction, and horizontal adjustment of the measuring position.
