Description

Technical Field

[0001] This utility model relates to the field of monitoring the volumetric water content of black locust trees, specifically a device for collecting the volumetric water content and environmental factors of black locust trees. Background Technology

[0002] Black locust is a fast-growing tree species, tolerant of drought and poor soil, with a well-developed root system and a wide ecological niche. Research on the trunk water content of black locust can provide insights into its water storage mechanisms in arid environments, explore its survival strategies under drought adversity, and investigate the relationship between environmental factors (such as soil moisture, climate conditions, and topography) and the trunk water content of black locust. This helps reveal the patterns of water resource utilization during plant growth and development, providing theoretical support for plant ecology and ecological engineering. A deeper understanding of the trunk water content of black locust and its relationship with environmental factors also contributes to the rational use of water resources, improving agricultural and forestry production efficiency and ecosystem stability, and promoting ecological restoration and economic development in arid regions.

[0003] Currently, the usual practice is to collect data on the volumetric water content and environmental factors of Robinia pseudoacacia, and then analyze the collected data. However, the data collection work mostly relies on manual operation of the corresponding collection equipment, which is not only inefficient but also cannot achieve real-time monitoring and continuous recording of the volumetric water content and environmental factors of Robinia pseudoacacia, affecting the accuracy of the results. To address this, we propose a collection device for the volumetric water content and environmental factors of Robinia pseudoacacia. Utility Model Content

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1 A device for collecting data on the volumetric water content and environmental factors of Robinia pseudoacacia (yew tree) is disclosed. This device, by studying the trunk water content of Robinia pseudoacacia and its relationship with environmental factors, can provide new insights and evidence for a deeper understanding of the ecological adaptation mechanisms of plants in arid environments, enrich plant ecology theory, deepen the understanding of the interaction between the trunk water content of Robinia pseudoacacia and environmental factors, and contribute to the formulation of scientific and reasonable ecological environmental protection policies and sustainable development strategies, thereby promoting the improvement of the ecological environment and the sustainable development of human society. The device includes:

[0037] Adjustable mounting rod for installation in the area of ​​black locust trees to be monitored;

[0038] The environmental factor acquisition unit, mounted on an adjustable mounting pole, is used to collect environmental factor data in real time. The environmental factor data includes precipitation data, surface horizontal radiation data, soil temperature and humidity data, and air temperature and humidity data.

[0039] Several locust data acquisition units 8 are used to collect locust tree trunk data from several locust trees respectively. The locust tree trunk data includes locust tree trunk volume water content data and trunk temperature data.

[0040] Electrical mechanism 11 is mounted on an adjustable mounting rod and electrically connected to the environmental factor acquisition unit and the locust tree data acquisition unit 8. It is used to control the operation of the environmental factor acquisition unit and the locust tree data acquisition unit 8, and to send the collected environmental factor data and locust tree trunk data to an external monitoring terminal for processing and analysis.

[0041] The aforementioned electrical mechanism 11 is existing technology, including, for example, a housing, a controller located inside the housing, and a wireless communicator. The controller controls the electrical equipment in the environmental factor acquisition unit and the black locust data acquisition unit 8. The wireless communicator can receive control signals sent by an external monitoring terminal and send the collected environmental factor data and black locust trunk data to the external monitoring terminal. The external monitoring terminal processes and analyzes the data to obtain the relationship between the environmental factor data and the volumetric water content of the black locust tree.

[0042] The aforementioned external monitoring terminal belongs to existing technology, such as computer equipment. The external monitoring terminal can use Excel 2019 software to process and calculate data, use SPSS 22 to normalize the data of locust tree trunk volume water content and environmental factors, use Pearson correlation analysis to analyze the correlation between volume water content and environmental factors, and use Origin 2021 software to generate graphs.

[0043] Please see the appendix Figure 2 As a preferred embodiment, the locust data acquisition unit 8 includes an adjustable fixing frame for fixing to the outer wall of the locust tree trunk and a temperature and humidity sensor 85 provided on the adjustable fixing frame. The detection end of the temperature and humidity sensor 85 is used to insert into the detection hole opened on the outer wall of the locust tree trunk. The temperature and humidity sensor 85 and the electrical mechanism 11 can be electrically connected by wires.

[0044] When using it, select several locust trees and use an electric drill to drill holes (the holes are for detection) according to the length, diameter and distribution of the detection end of the temperature and humidity sensor 85. It is preferable to drill holes on the surface of the locust tree trunk 20cm above the ground to ensure that the temperature and humidity sensor 85 is in full contact with the tree trunk and to avoid interference from the external environment.

[0045] The temperature and humidity sensor 85 is modeled as TEROS-11, but is not limited to this one. It collects data on the trunk of the locust tree periodically.

[0046] In practice, the determination of trunk volumetric moisture content and the calculation of corrections can be performed using the drying method. For example, fallen logs from a locust forest are selected and cut. The obtained locust trunks are transported to the laboratory and placed underwater. The log blocks are then immersed in deionized water under vacuum overnight for hydration. The fresh weight of the blocks is then measured to an accuracy of 0.1g using a Sartorius balance (model 3808MP8 / 8-1). (Germany) and volume were determined using the water displacement method. A pre-determined weight TEROS-11 sensor was then installed in the wood block, and an EM50 data logger was used. The wood block was then allowed to dry on a laboratory bench for several hours (depending on observed weight loss), then completely wrapped in paraffin film and placed in a plastic bag overnight for equilibration and measurement again. This process was repeated, and five sets of weight and VWC measurements were obtained for each wood block. The wood block was then dried at 60°C for one week to measure the dry weight. VWC was calculated as (fresh weight - dry weight) / fresh volume. The VWC measured by the drying method and the VWC measured by the TEROS-11 were then fitted to derive a relationship between the two, thereby correcting subsequent measurements of trunk volumetric water content.

[0047] Preferably, the adjustable mounting rod in this embodiment includes:

[0048] Support rod 1, one end of which is fixedly provided with an insert 3. The vertical cross section of the insert 3 is triangular and is used to insert into the area of ​​the black locust tree to be monitored.

[0049] Support rod 2 4 is movably inserted into the other end of support rod 1 1. Support rod 2 4 is fixed to support rod 2 4 by fastener 6, which is, for example, a bolt or a buckle.

[0050] The base plate 2 is fixedly sleeved on the outer wall of the support rod 1 and located above the insert 3. It is used to contact the ground of the locust area to be monitored. The setting of the base plate 2 increases the contact area between the data acquisition device and the ground of the locust area to be monitored, effectively preventing the adjustable mounting rod from tipping over due to external factors.

[0051] Preferably, the environmental factor acquisition unit in this embodiment includes:

[0052] Rain gauge 7, mounted on support pole 2 4, is used to collect precipitation data. For example, the rain gauge 7 is a TE525 tipping bucket rain gauge. The amount of precipitation and the duration of precipitation are observed through the rain gauge 7.

[0053] The total radiation sensor 10 is mounted on the second support 4 and is used to collect horizontal radiation data of the ground surface. For example, the total radiation sensor 10 is a CMP-3 total radiation sensor.

[0054] An air temperature and humidity sensor 12 is mounted on support rod 1 and is used to collect air temperature and humidity data. For example, the air temperature and humidity sensor 12 is an HMP155A air temperature and humidity sensor.

[0055] Several soil temperature and humidity sensors 9 are inserted into the soil around several locust trees to collect soil volume moisture data around the locust trees. For example, soil temperature and humidity sensors 9 are monitored using a soil temperature and humidity probe (treos-11, Beijing Ligaotai).

[0056] Similarly, soil volumetric water content can also be corrected using the drying method. For example, soil samples are taken near the root zone of the black locust tree using a ring cutter, then brought back to the laboratory and weighed fresh. The ring cutter cap is then opened, an EC-5 probe is inserted into the soil, and the soil column is placed at room temperature on a balance to evaporate moisture. The change in fresh weight is recorded, and the change in soil volumetric water content is recorded simultaneously using the probe. After a period of time, the ring cutter soil sample is placed in an oven to dry to constant weight. Soil VWC is calculated as (fresh weight - dry weight) / fresh (ring cutter) volume. Then, the VWC measured by the drying method and the VWC measured by the EC-5 probe are fitted to obtain the relationship between the two, thereby correcting the subsequent calculations of soil volumetric water content.

[0057] Preferably, the adjustable mounting bracket in this embodiment includes:

[0058] Two opposing arc-shaped pieces 81 are used to fit onto the outer wall of the locust tree trunk. The inner wall of the arc-shaped piece 81 is provided with an elastic rubber pad to prevent the arc-shaped piece 81 from contacting the outer wall of the locust tree trunk and causing damage to the outer wall. Both ends of one arc-shaped piece 81 are connected to a fixing band 86, which can be made of elastic rubber material. The outer wall of the fixing band 86 is movably fitted with a fixing block, and the fixing block is fixed to the outer wall of the end of the other arc-shaped piece 81. Fixing holes 87 are evenly opened on the fixing band 86.

[0059] The pin 88 is movably inserted on the outside of the fixing block, with one end extending into the fixing block and passing through a fixing hole 87 on the fixing band 86.

[0060] When in use, the adjustable fixing bracket can be used to fit two arc-shaped pieces 81 onto the outer wall of the locust tree trunk. Then, the fixing strap 86 in one arc-shaped piece 81 passes through the fixing block in the other arc-shaped piece 81, and then the pin 88 is inserted so that it enters the fixing hole 87 on the fixing strap 86, thereby fixing the two arc-shaped pieces 81 to the outer wall of the locust tree trunk.

[0061] Please see the appendix Figure 3 As a preferred embodiment, the arc-shaped component 81 in this embodiment has an arc-shaped opening 82, and a mounting block 83 is movably provided in the arc-shaped opening 82. The mounting block 83 can be detachably connected to the temperature and humidity sensor 85 using a bolt-like structure. The mounting block 83 has a through-hole for the temperature and humidity sensor 85 to pass through. The upper and lower ends of the mounting block 83 are provided with grooves. The bottom of the groove is connected to a round-headed locking rod 89 through an elastic element 810. The elastic element 810 is, for example, a spring. The upper and lower inner walls of the arc-shaped opening 82 are evenly provided with insertion holes 84 for the round-headed locking rod 89 to be inserted, which facilitates adjusting the position of the temperature and humidity sensor 85 or adding or removing the temperature and humidity sensor 85 at the arc-shaped opening 82.

[0062] The temperature and humidity sensor 85 is disassembled and installed as follows: When disassembling, press the round-headed locking rod 89 in the socket 84 to squeeze the elastic element 810 to move towards the bottom of the groove, and then pull the corresponding mounting block 83 away from the arc-shaped opening 82; when installing, press the round-headed locking rod 89 in the mounting block 83 to squeeze the elastic element 810 to move towards the bottom of the groove, insert the mounting block 83 into the arc-shaped opening 82, so that the round-headed locking rod 89 corresponds to a socket 84, and then the round-headed locking rod 89 is reset and enters the socket 84 under the action of the elastic element 810 to complete the installation.

[0063] Preferably, the outer wall of the second support rod 4 in this embodiment is provided with a photovoltaic mechanism 5 that is electrically connected to the electrical mechanism 11. The photovoltaic mechanism 5 includes a photovoltaic panel, a storage battery, etc., and is used to supply power to the electrical equipment in this device.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
