Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, in particular to a forestry investigation environment sampling device. Background Art

[0002] Environmental sampling in forestry surveys is a key link in forestry research and management. In the vast forest area, precise sampling can provide a deep insight into the ecological environment. Soil sampling is the basic part. Soil at different depths is collected to analyze indicators such as texture, pH, fertility, etc., to help determine the soil's suitable tree species and provide a basis for afforestation planning. Water quality sampling targets water bodies in forest areas to test pH, dissolved oxygen, pollutants, etc. to ensure the health of water sources and maintain forest ecological stability. Biological sampling includes plants, animals and microorganisms, analyzing plant species, animal distribution and microbial communities, and assessing biodiversity. These sampling operations collect data in all directions, laying a solid foundation for the protection and rational development and utilization of forest resources, and are of great significance to maintaining ecological balance and promoting sustainable development of forestry.

[0003] Forestry survey and sampling plays an extremely important role in preventing forest fires. However, the mechanism of forest fires is extremely complex and is not determined by a single factor such as soil moisture. Forest fires are often caused by the interaction of multiple factors such as meteorological conditions, vegetation conditions, topography, and human activities.

[0004] At present, in forestry survey and sampling work, the determination of soil moisture usually relies only on soil sampling. The staff selected multiple points in the area and sampled the soil at different depths to determine the soil moisture conditions, and then tried to judge the probability of forest fires in the area. However, this single sampling and judgment method has significant limitations. On the one hand, only focusing on soil moisture, while ignoring many equally critical factors such as the continuous changes in temperature, large fluctuations in humidity, and the flammable characteristics of vegetation deciduous leaves, it is difficult to fully and accurately reflect the potential risks of forest fires. On the other hand, only assessing the probability of fire by soil moisture cannot effectively cope with the complex and changeable forest environment, resulting in large deviations in the assessment results of the probability of forest fires, and it is difficult to provide solid and reliable data support for the prevention of forest fires. Therefore, those skilled in the art have proposed a forestry survey environment sampling device to solve the above-mentioned technical problems. Summary of the invention

[0014] Working principle: When surveying and sampling forestry, the staff generally adopts a chessboard survey sampling method, that is, the entire large forestry survey sampling area is divided into several small areas according to the chessboard layout, and then a survey point is randomly selected in each area, and the device is installed on the main body of the tree trunk in the survey point for a period of time. Finally, the sampling data generated by each survey point is sorted out and the average value of the data is taken to complete the survey and sampling work of the entire large forestry area. The probability of forest fires in the area is evaluated through the data generated by these samples, thereby completing the sampling processing of forestry surveys in large areas; When conducting forestry surveys and sampling in a single small area, the adaptation and adjustment fixing mechanism is first started. When conducting surveys and sampling in a single small area, the staff first randomly selects a tree in the area, and then the staff fits the two semicircular shells on the trunk body. When installing the semicircular shells, the staff can squeeze the sponge ring seat in the semicircular shell according to the thickness of the trunk body, so that the sponge ring seat fits the trunk body. After the semicircular shell is installed, the staff tightens the semicircular shell and the connection thereon through the locking bolts. The seat is locked and fixed on the trunk body, and then when the semicircular shell is locked and fixed on the trunk body, the semicircular shell and the sponge ring seat therein move downward due to gravity, and the sponge ring seat simultaneously drives the rubber ring piece thereon to move downward, so that the rubber ring piece originally in a horizontal state changes to a vertical state and fits with the surface of the trunk body, thereby increasing the friction between the semicircular shell and the sponge ring seat and the surface of the trunk body, thereby improving the fixing effect of the overall device on the trunk body during installation, thereby completing the adaptation, adjustment and fixing processing of trunk bodies with different outer diameters;After the semicircular shell on the trunk body is installed and fixed, the staff will install and fix the remaining devices. After the installation of the entire device is completed, the subsequent forestry survey sampling process can be started, and then the range root sampling mechanism is started. When the staff installs the installation tube, the staff inserts the installation tube into the soil around the trunk body in a circular dispersion manner, and supports and fixes the installation tube and the overall device thereon through the support ring piece on the installation tube. When the installation tube is inserted into the soil around the trunk body, the annular blade at the bottom of the installation tube cuts off the plant roots in the soil, thereby ensuring that the installation tube is smoothly inserted into the soil around the trunk body, so as to facilitate the subsequent soil sampling process in the area around the trunk body. Before the installation tube is inserted into the soil around the trunk body, the staff can adjust the position of the sampling tube in the installation tube according to the sampling depth. When adjusting it, the staff can rotate the adjustment frame in the connecting part, so that the adjustment frame rotates and moves up and down on the internal threaded wall of the connecting part. Then, after the adjustment of the adjustment frame is completed, the staff inserts the sampling tube into the separation part The sampling tube is inserted into the soil around the trunk body, and the soil enters the inside of the sampling tube through the ring edge on the installation tube, thereby completing the sampling of the root soil around the trunk body. When the staff takes out the soil sample in the sampling tube, the staff separates the connecting part and the separation part, and then draws the sampling tube from the separation part. After the sampling tube is drawn out, the staff rotates the locking sleeve on the external thread wall to release the fixing of the locking sleeve to the sampling tube. Then, the staff opens the first of the two combined separation half-tubes to obtain the soil sample near the root of the trunk body in the area. The staff can collect and sample the number data of harmful organisms such as pathogens and nematodes in the soil of the area according to the soil samples, and can also collect and sample the water content data in the soil of the area according to the soil samples, so as to make a comprehensive judgment on the probability of forest fire in the area through these data, thereby completing the sampling of the soil within the root range of the trunk body in the area.At the same time, the humidity load sampling mechanism is started. When the device is installed on one of the tree trunks in a small area, as time goes by, the moisture in the environment of the area is gradually absorbed by the absorbent cotton board, so that the moisture in the absorbent cotton board gradually increases. As the moisture content in the absorbent cotton board continues to increase, the moisture in the absorbent cotton board is drained through the water diversion line inside it, so that the moisture in the absorbent cotton board is drained into the moisture collection chamber for collection. After completing the investigation and sampling, the staff will collect the liquefied water in the moisture collection chamber and measure the moisture content in the absorbent cotton board. Through these two comprehensive data, the moisture content in the air in the area is judged. At the same time, during the use of the device, the dry and separated dead branches and fallen leaves on the trunk body fall into the load collection chamber on the partition plate for collection. After the sampling is completed, the staff can collect the fire load information data such as the number and weight of dead branches and fallen leaves in the load collection chamber, and combine the above-mentioned data information on the moisture content in the air to make a comprehensive assessment of the fire load situation in the area. This completes the sampling and processing of the air humidity and fire load in the area; at the same time, the regional biological sampling mechanism is started. When the device is used, the insects in the area are first captured by installing the insect net on the ring plate, and then the insects around the trunk body are lured by the dual cooperation of the insect trap lamp in the mounting seat and the attractant in the inner cavity, so that the insects in the area are trapped by the sticky insect film in the cavity. After the sampling is completed, the staff collects information data such as the types and quantities of pests on the insect net and the sticky insect film, and makes a comprehensive judgment on the probability of fire and insect pests in the area through such data information, so as to complete the sampling and processing of the organisms in the small area; after all kinds of sampling are completed, the staff will sort out the sampling data information generated by each small area, and average the data, and then the staff can combine various data information to make a comprehensive judgment on the probability of fire and other types of disasters in the entire forestry area, so as to complete the investigation and processing of the forestry environment area. ;

[0015] The present invention provides a forestry survey environment sampling device, which has the following beneficial effects: 1. The present invention adds and sets an adaptable and adjustable fixing mechanism. When performing environmental sampling operations in forestry surveys, the mechanism can be conveniently adjusted and fixed according to the different outer diameters of the trunks when facing tree trunks of different thicknesses, thereby greatly improving the adaptability of the overall device in practical applications. Whether it is a slender young tree or a sturdy adult tree, it can be perfectly adapted. At the same time, by adopting multiple fixing methods, the stability of the device during use is effectively enhanced, providing a solid guarantee for the smooth and accurate implementation of environmental sampling in forestry surveys, and greatly reducing the occurrence of sampling data errors or sampling failures caused by unstable fixation.

[0016] 2. The present invention increases and sets a range root sampling mechanism. When the overall device is in use, the mechanism can accurately collect multiple groups of soil samples at different distances around the tree trunk body in the sampling area. Through multiple groups of soil sample information at different positions, on the one hand, the types and quantities of harmful organisms such as pathogens in the soil can be determined in detail, and the health status of the ecosystem can be understood. On the other hand, the soil moisture content can be accurately determined, and the degree of soil dryness and wetness can be understood. By integrating and analyzing the comprehensive data information of these two aspects, the probability of forest fires in the area can be scientifically and accurately evaluated, providing key decision-making basis for forest fire prevention work and facilitating the effective protection of forest resources.

[0017] 3. The present invention increases and sets a humidity load sampling mechanism. During the forestry survey and sampling process, the mechanism can not only sample and measure the air humidity and air moisture content in a small area to obtain key meteorological data, but also sample the types and quantity information of fire loads such as dead branches and leaves around the main body of the tree trunk. Then, by deeply integrating and comprehensively evaluating the two types of sampling data, the comprehensive judgment of the probability of fire in the area can be accurately and comprehensively achieved, laying a solid data foundation for forestry fire prevention and resource protection.

[0018] 4. The present invention increases and sets up regional biological sampling mechanisms. In the process of forestry surveys, the mechanisms can not only trap insects in the area around the device, but also judge the health of the forests in the area by the types and numbers of the trapped insects. In addition, by deeply analyzing the types and numbers of the pests, the imbalance of the ecosystem in the area can be understood. Through comprehensive analysis of multiple data, a comprehensive and integrated assessment of the probability of forest fires in the area can be made, providing a key basis for the all-round protection of forestry resources.

[0019] 5. The present invention innovatively adopts a method of multiple survey sampling of soil moisture, air moisture, fire loads and regional organisms, breaking through the inherent limitations of traditional single sampling. In forestry areas, single sampling and data judgment are very likely to be biased due to one-sidedness. The present invention cleverly integrates a variety of data information to comprehensively evaluate the probability of fire from multiple perspectives such as ecology, meteorology, and combustibles. In the complex and changeable forest environment, whether it is an area with complex terrain, unpredictable climate, or diverse vegetation, the device can accurately analyze the regional forestry environment, thereby facilitating the provision of comprehensive and reliable decision-making support for forest fire prevention work and effectively ensuring the safety of forestry resources.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please see attached Figure 1 - Attachment Figure 2 , an embodiment of the present invention provides a forestry survey environment sampling device, including a bottom plate 11, which is used as a basic component of the overall device for assembling and carrying various processing mechanisms and their subordinate structural parts; Please see attached Figure 5- Attachment Figure 6 , an adaptable and adjustable fixing mechanism, which is arranged in the middle of the inner side of the bottom plate 11, and is used to adjust the entire device to adapt to forestry trees of different outer diameters when in use, and to fix them; The adaptation and adjustment fixing mechanism includes a semicircular shell 1, two semicircular shells 1 are arranged on the inner side of the bottom plate 11, and the two semicircular shells 1 are rotatably connected at the outer wall of one side. The middle and lower parts of the outer wall of the semicircular shell 1 are provided with protrusions for limiting the bottom plate 11. A sponge ring seat 2 is arranged in the middle part of the inner side of the semicircular shell 1, and a plurality of rubber ring sheets 15 are fixedly connected to the inner wall of the sponge ring seat 2 at equal intervals. A connecting seat 16 is fixedly connected to the middle part of one side of the outer wall of the semicircular shell 1, and the middle parts of the two connecting seats 16 are connected by a plurality of locking bolts 17.

[0024] When the adaptation and adjustment fixing mechanism is started, when surveying and sampling a single small area, the staff first randomly selects a tree in the area, and then the staff installs the two semicircular shells 1 on the trunk body. When installing the semicircular shell 1, the staff can squeeze the sponge ring seat 2 in the semicircular shell 1 according to the thickness of the trunk body, so that the sponge ring seat 2 fits the trunk body, and then after the semicircular shell 1 is installed, the staff uses the locking bolt 17 to lock and fix the semicircular shell 1 and the connecting seat 16 thereon to the trunk body.

[0025] After that, when the semicircular shell 1 is locked and fixed on the trunk body, the semicircular shell 1 and the sponge ring seat 2 therein move downward due to gravity, and the sponge ring seat 2 moves downward while simultaneously driving the rubber ring piece 15 thereon to move downward, so that the rubber ring piece 15 that was originally in a horizontal state changes to a vertical state and fits with the surface of the trunk body, thereby increasing the friction between the semicircular shell 1 and the sponge ring seat 2 and the surface of the trunk body, thereby improving the fixing effect of the overall device on the trunk body during installation, thereby completing the adaptation, adjustment and fixing processing of trunk bodies with different outer diameters.

[0026] Please see attached Figure 7 - Attachment Fig. 9 , a range root sampling mechanism, which is arranged around the outer side of the bottom plate 11 and is used to sample the soil around the tree roots; The range root sampling mechanism includes a side wall ring plate 4, and a side wall ring plate 4 is arranged on the outer side of the bottom plate 11. A plurality of mounting tubes 7 are arranged in a circular array at the edges of the bottom of the bottom plate 11 and the side wall ring plate 4. The mounting tubes 7 are arranged from top to bottom in sequence as a connecting portion 28 and a separating portion 29. The bottom end of the connecting portion 28 is threadedly connected to the separating portion 29. A supporting ring sheet 9 is arranged in the middle and lower part of the outer wall of the connecting portion 28, and a ring cutting edge 32 is arranged at the bottom of the separating portion 29.

[0027] The bottom plate 11, the side wall ring plate 4, the partition plate 5 and the mounting ring plate 10 in the overall device are not a whole. For portability after use, the bottom plate 11, the side wall ring plate 4, the partition plate 5 and the mounting ring plate 10 are generally cut into four equal parts. When in use, the staff splices them together by plugging or gluing.

[0028] When the range root sampling mechanism is started, when the staff installs the installation tube 7, the staff inserts the installation tube 7 into the soil around the trunk body in a circularly dispersed manner, and supports and fixes the installation tube 7 and the overall device thereon through the support ring piece 9 on the installation tube 7. When the installation tube 7 is inserted into the soil around the trunk body, the annular cutting edge 32 at the bottom of the installation tube 7 cuts off the plant roots in the soil, thereby ensuring that the installation tube 7 is smoothly inserted into the soil around the trunk body, thereby facilitating the subsequent soil sampling and processing of the area around the trunk body.

[0029] The range root sampling mechanism also includes an internal threaded wall 30. The internal threaded wall 30 is arranged on the inner wall of the connecting part 28. The adjusting frame 18 is threadedly connected to the internal threaded wall 30. A limiting ring seat 21 is arranged in the middle and lower part of the inner wall of the separating part 29. A sampling tube 20 is arranged on the top of the limiting ring seat 21. The top of the sampling tube 20 passes through the separating part 29 and contacts with the bottom end of the corresponding adjusting frame 18.

[0030] Before the installation tube 7 is inserted into the soil around the trunk body, the staff can adjust the position of the sampling tube 20 in the installation tube 7 according to the sampling depth. When adjusting it, the staff can rotate the adjustment frame 18 in the connecting part 28, so that the adjustment frame 18 can rotate and move up and down on the internal threaded wall 30 of the connecting part 28. Then, after the adjustment of the adjustment frame 18 is completed, the staff will insert the sampling tube 20 into the separation part 29, and limit it through the adjustment frame 18 and the limiting ring seat 21 in the separation part 29, so that it can be adapted to sampling at different depths.

[0031] The range root sampling mechanism also includes a separation half cylinder 31. The sampling cylinder 20 is composed of two semicircular separation half cylinders 31. The middle and upper sides of the outer wall of the separation half cylinder 31 are provided with external thread walls 22, and the locking sleeves 19 are threadedly connected to the external thread walls 22.

[0032] And when the installation tube 7 is inserted into the soil around the trunk body, the soil enters into the sampling tube 20 through the annular cutting edge 32 on the installation tube 7, thereby completing the sampling process of the root soil around the trunk body. When the staff takes out the soil sample in the sampling tube 20, the staff separates the connecting part 28 and the separating part 29, and then draws the sampling tube 20 into the separating part 29. After the sampling tube 20 is drawn out, the staff rotates the locking sleeve 19 on the external threaded wall 22, thereby releasing the fixing of the locking sleeve 19 to the sampling tube 20.

[0033] Afterwards, the staff will open the first of the two combined separation half cylinders 31 to obtain soil samples near the roots of the main trunks in the area. The staff can collect and sample the number data of pathogens, nematodes and other harmful organisms in the soil of the area based on the soil samples. At the same time, the staff can also collect and sample the water content data in the soil of the area based on the soil samples, so as to make a comprehensive assessment of the probability of forest fires in the area through these data, thereby completing the sampling and processing of the soil within the root system of the main trunks in the area.

[0034] In forestry surveys, soil sampling at different locations of tree roots is of great significance. Soil moisture content is closely related to forest fires, and the soil around the roots can reflect the condition of trees obtaining water. If the soil moisture content is low, trees are prone to dry up, forest combustibles increase, and the risk of fire increases. By collecting soil deep and shallow in the root system and comparing the moisture content, the overall drought level of the forest area can be accurately determined and the possibility of fire can be predicted. The nutrient content of the soil should not be ignored either. Trees on poor soil grow poorly, have weak resistance, and are more easily ignited. Differences in soil nutrients at different locations affect the health of trees, and thus affect the risk of forest fires. For example, soil nutrients are consumed in areas with dense roots. If nutrients are scarce, trees are prone to decay, increasing the risk of fire. In addition, soil microbial activity can also provide clues. Certain microorganisms are active in specific environments. For example, during drought, the activity of some decomposers is restricted, organic matter in the soil decomposes slowly, and litter accumulates, providing fuel for fires. Sampling and analyzing root soil can detect such changes in advance and help prevent forest fires.

[0035] Please see attached Figure 3 - Attachment Figure 4 , a humidity load sampling mechanism, which is arranged on the upper part of the bottom plate 11, and is used to sample and process the air humidity and fire load in the area around the tree; The humidity load sampling mechanism also includes a water-absorbing cotton plate 3. A plurality of water-absorbing cotton plates 3 are arranged in a circular array on the top of the partition plate 5. A moisture collecting chamber 13 is formed between the bottom of the partition plate 5 and the top of the bottom plate 11. A plurality of water guide lines 14 are evenly spaced in the middle of the inner side of the water-absorbing cotton plate 3, and the ends of the water guide lines 14 penetrate the partition plate 5 and extend to the interior of the moisture collecting chamber 13.

[0036] When the humidity load sampling mechanism is started, when the device is installed on one of the tree trunks in a small area, as time goes by, the moisture in the environment of the area is gradually absorbed by the absorbent cotton board 3, so that the moisture in the absorbent cotton board 3 gradually increases. As the moisture content in the absorbent cotton board 3 continues to increase, the moisture in the absorbent cotton board 3 is drained through the water diversion line 14 therein, so that the moisture in the absorbent cotton board 3 is drained into the moisture collection chamber 13 for collection. After completing the investigation and sampling, the staff collects the liquefied water in the moisture collection chamber 13 and measures the moisture content in the absorbent cotton board 3. The moisture content in the air in the area is judged through these two comprehensive data.

[0037] The humidity load sampling mechanism includes a partition plate 5. The partition plate 5 is arranged on the upper part of the bottom plate 11, and the outer edge of the partition plate 5 is connected to the corresponding position of the inner wall of the side wall ring plate 4. The upper part of the partition plate 5 is provided with a load collection cavity 33 for collecting dead branches and fallen leaves impurities dropped from forestry trees in the area.

[0038] At the same time, during the time when the device is used, the dry and separated dead branches and fallen leaves on the trunk body fall into the load collection chamber 33 on the partition plate 5 for collection. After the sampling is completed, the staff can collect fire load information data such as the number and weight of dead branches and fallen leaves in the load collection chamber 33, and combine it with the above-mentioned data information on the water content in the air to make a comprehensive assessment of the fire load situation in the area, thereby completing the sampling and processing of the air humidity and fire load in the area.

[0039] In forestry survey environmental sampling, sampling of fire loads such as air humidity and dead branches and leaves is crucial to preventing and judging the probability of forest fires. Air humidity directly affects the possibility of forest fires. When air humidity is low, vegetation in the forest, including trees, shrubs and herbs, evaporates quickly and becomes dry and flammable. For example, in a continuous low humidity environment, the needles of coniferous trees lose water, and their oil content increases relatively, making them more easily ignited. Real-time monitoring of air humidity can provide timely warnings of high-risk forest fires once the value falls below the safety threshold. Litter is the main fire load in forests, and its accumulation and dryness are key factors. In dry climates, large amounts of accumulated litter act as natural ignition materials. In humid environments, microorganisms have a stronger decomposition effect on litter, reducing potential combustibles; in dry environments, decomposition is hindered and litter continues to accumulate. By regularly sampling litter and assessing its moisture content and accumulation thickness, the potential risk of fire can be accurately determined, providing a strong basis for the prevention and fighting of forest fires.

[0040] Please see attached Fig.10 - Attachment Fig.11 , a regional biological sampling mechanism is arranged on the top outer side of the base plate 11 and is used to sample the number and type of organisms in the area around the trees.

[0041] The regional biological sampling mechanism includes a mounting ring plate 10, a mounting ring plate 10 is arranged on the top of the side wall ring plate 4, a plurality of mounting seats 8 are arranged in a circular array on the top of the mounting ring plate 10, the mounting seats 8 are connected by an insect catching net 6, a through cavity 12 is opened on the upper and lower sides of the middle of the mounting seat 8, insect sticky film sheets 24 are arranged on both sides of the inner wall of the through cavity 12, an inner cavity 27 is opened in the middle of the inner side of the mounting seat 8, an attractant 26 is arranged inside the inner cavity 27, a plurality of dispersing holes 25 are equidistantly arranged in the middle of the mounting seat 8 for dispersing the smell of the attractant 26 in the inner cavity 27, and an insect attractant lamp 23 is arranged on the inner wall side of the through cavity 12 away from the inner cavity 27.

[0042] When the regional biological sampling mechanism is started, when the device is used, the insects in the area are first captured by the insect catching net 6 on the mounting ring plate 10, and then the insects around the trunk body are lured by the dual cooperation of the insect catching lamp 23 in the mounting seat 8 and the attractant 26 in the inner cavity 27, so that the insects in the area are trapped by the sticky insect film 24 in the through cavity 12. Then, when the sampling is completed, the staff collects information data such as the type and quantity of pests on the insect catching net 6 and the sticky insect film 24, and makes a comprehensive judgment on the probability of fire and insect pests in the area through such data information, thereby completing the sampling and processing of organisms in a small area.

[0043] There are many kinds of insects in the forest, and each has its own function. The insect community in a healthy forest is stable. If the number of pests such as bark beetles in a certain area increases dramatically, it may be a red light for the health of the trees, which are easily ignited by fire sources, increasing the risk of fire. Some insects are sensitive to environmental humidity and temperature. For example, the number of some moths decreases when the humidity is low. Low humidity is one of the causes of forest fires. By monitoring the number of such insects, the environmental humidity can be indirectly known and the probability of fire can be predicted. At the same time, insects affect forest combustibles. For example, the number of insects that feed on fallen leaves decreases, and fallen leaves accumulate and become fuel for fires. In addition, some insects have abnormal behaviors before a fire, such as ants transferring supplies in advance. Observing them can warn of early fire hazards and help forestry workers take preventive measures in time to reduce the possibility of forest fires.
