A forestry survey device

Abstract

The present invention discloses a forestry survey device, which relates to the field of environmental measurement. This solution uses a pneumatic component to drive a rotating seat and a glass cover to rotate, so as to realize automatic cleaning of the surface and inner wall of the glass cover, thereby avoiding the problem of the mobile cleaning component blocking sunlight in the prior art. By ensuring that the cleaning component faces north during installation, the airflow is used to clean the outer surface of the glass cover and the rubber strip is used to clean the inner wall fog, so as to ensure that the cleaning effect is not affected by wind stop. At the same time, the pneumatic component cooperates with the speed sensor to monitor the wind speed in real time, and automatically adjusts the height and center of gravity position of the support component according to the change of wind force. When the wind speed increases, the center of gravity automatically decreases to enhance wind resistance. Under extreme wind speeds, the wind cover opens downward to achieve protection. In addition, the slide trough and counterweight sleeve structure further enhance the wind resistance when the wind speed is higher than the threshold, ensuring the long-term stable operation of the device in different wind environments.

Description

Technical Field

[0001] The invention relates to the field of environmental measurement, in particular to a forestry survey device. Background Art

[0002] Forestry survey is an important work involving forest resource assessment, environmental monitoring and ecological protection. The process usually includes forest resource inventory, vegetation survey, biodiversity monitoring, soil analysis and water resource assessment.

[0003] Light directly affects the health of forest ecosystems and the distribution and dynamics of plant growth. Plant growth requires photosynthesis, and the intensity, duration, and quality of light will affect plants. By measuring light conditions, we can help determine the potential differences in plant growth in different areas of the forest, especially in the growth assessment of canopy and understory vegetation. Light distribution can reflect the complexity of forest structure and stand density. For example, reduced light in the canopy may indicate limited understory light resources, which will directly affect the diversity of understory plants. By measuring light conditions at different levels, we can further understand the hierarchical structure of the forest and the degree of canopy closure, thereby assessing stand density and tree competition. Healthy ecosystems usually have reasonable light distribution and plant growth status.

[0004] If there is insufficient or excessive light in certain areas, it may be due to forest gaps caused by human destruction or natural disasters (such as windstorms and fires), thus destroying the overall structure of the forest. Through light measurement, these signs of ecological damage can be discovered earlier and protective measures can be taken in time. Some pests may prefer environments with less light. By understanding the light conditions in forest areas, it is possible to arrange pest and disease control work more reasonably. Light changes are an important dimension of climate change. Changes in light levels in forest areas may reflect larger climate changes, so long-term monitoring of light helps accumulate climate data and provide reference for more extensive ecological research.

[0005] Based on this, most of the current forestry lighting detection is carried out all year round. In addition to dust affecting the accuracy of light detection, frost, snow and fog caused by temperature changes will also interfere with sunlight detection. In addition, under long-term deployment, climate change and environmental changes have uncontrollable impacts. For example, grass leaves in areas with good light can block sunlight at close range, causing inaccurate detection. In addition, the impact of climate change such as strong winds on equipment will challenge stability under long-term deployment. Summary of the invention

[0018] As a further description of the above technical solution: a plurality of guide grooves for sliding with the fixed wheel are provided on the surface of the box body.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] When the present invention is in use, the pneumatic assembly drives the rotating seat to rotate under the action of the ambient wind force, and the rotating seat drives the glass cover to rotate. At the same time, the rotating seat drives the transmission wheel to rotate through the side wall. The elastic brush is supported by the arc-shaped inner frame and the arc-shaped outer frame and is positioned on the north side of the light detector to avoid blocking the sunlight. The elastic brush starts to rotate with the cooperation of the transmission wheel and cleans the outer surface of the glass cover in a rotating state. At the same time, the arc-shaped inner frame uses a rubber strip to clean the mist on the inner wall of the glass cover. Compared with the prior art, the present invention avoids the cleaning assembly from blocking the sunlight when it is moving and avoids obstruction caused by the cessation of the airflow by making the cleaning assembly face north during the overall installation and maintaining the cleaning under the action of the airflow. By setting the cleaning assembly to a specified direction, the rotating design of the glass cover not only plays a protective role, but also avoids blocking the sunlight during cleaning.

[0021] At the same time, this solution can detect wind speed by cooperating with the speed sensor when the pneumatic component rotates with the rotating seat, and can detect the light intensity of the light detector to detect the light and wind data of the delivery area. At the same time, if the wind is strong, as the wind increases, the centrifugal force of the counterweight sleeve gradually increases with the increase in speed and pulls the tension spring to extend. When the counterweight sleeve moves, the length of the support assembly changes through the transmission module. This solution uses multiple tension springs to elastically support at a constant height. When the length of the tension spring changes, the overall height of the electric control box is reduced at the same time, which can achieve that the greater the wind speed, the lower the overall height. After the center of gravity is lowered, the overall wind resistance is improved, and the self-protection state in the strong wind state is achieved;

[0022] At the same time, as the wind speed increases, the convex point inside the counterweight sleeve slides to a specific position of the slide slot, so that the inclined area of ​​the slide slot provides a deflection force under the action of the convex point. As the counterweight sleeve is pressed, the slide cylinder rotates on the surface of the support rod, and the wind shield deflects until the wind speed reaches the maximum threshold and the opening of the wind shield is completely facing downward, achieving a self-protection state and avoiding excessive rotation speed. It can further improve the wind resistance in relatively open areas and ensure the stability of year-round deployment.

[0023] At the same time, in a light wind state, the pneumatic component that moves clockwise around the main shell moves, and with the cooperation of the fixed wheel and the moving wheel, the cutter can rotate counterclockwise while revolving clockwise, so that the swaying grass can be pushed aside to avoid obstruction, and at the same time, the growth of plants at a close distance can be suppressed. When the wind speed is high, the rapid revolution and high-speed rotation of the cutter can cut the grass leaves to prevent the device from being covered by weeds. At the same time, the grass leaves that have fallen nearby in a strong wind state can also be cut and pushed aside to avoid being covered and affecting detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following will be combined with the drawings in the embodiments 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.

[0044] Through light measurement, the growth environment of plants can be accurately evaluated, because light intensity directly affects the photosynthesis efficiency of plants, especially the significant difference in light at different levels of the forest and canopy, which can help analyze the growth potential of plants at each layer. At the same time, light distribution can reveal the structure and density of the forest. By measuring the light at the top, bottom and ground of the canopy, the degree of light shading of the canopy can be clearly shown, which helps to judge the hierarchical structure of the forest and the competition between trees. In addition, the distribution of light can reflect the health of the ecosystem. Light data can help to find gaps in the forest or tree damage caused by ecological destruction or natural disasters at an early stage, so as to facilitate timely protection measures. Light conditions also directly affect the distribution of pests and diseases and the possibility of forest fires. By obtaining the light conditions in different areas of the forest, it is possible to scientifically plan pest and disease control measures and fire prevention management. At the same time, long-term monitoring data of light provide basic data support for climate change research, especially by recording the trend of light changes in different seasons and regions, which can help scientific research and analysis of the response of the ecosystem to climate change. In summary, light measurement provides a reliable scientific basis for forestry surveys, ecological protection, and climate change research.

[0045] like Figure 1-Figure 13 As shown, the present invention provides: a forestry survey device, including a main housing 10 and a rotation speed sensor 70 and a light detector 50 installed thereon, the main housing 10 includes an electric control box 11 and a base assembly 12 installed on the top of the electric control box 11, a glass cover 13 is installed on the top of the base assembly 12, a cleaning assembly 30 for cleaning the inner and outer walls of the glass cover 13 is installed on the base assembly 12, and a support assembly 40 fixed to the ground is installed at the bottom of the electric control box 11;

[0046] When in use, the glass cover 13 is located on the rotating seat 122 of the base assembly 12. Only the rotating seat 122 of the entire base assembly 12 can rotate. It is installed on the surface of the adapter seat 121 through a bearing, and cooperates with the glass cover 13 to protect the adapter seat 121. The sealing seat 123 with the thread on the inner wall of the adapter seat 121 can isolate the electric control box 11 and keep the line connected. The partition frame 124 above the adapter seat 121 can lay the photovoltaic panel 60, and the line can go under the photovoltaic panel 60.

[0047] In addition to measuring wind speed and light detection, this solution can also install electronic thermometers and cameras on the surface of the partition to expand different functions as needed.

[0048] Based on the smaller size of the light detector 50, the rotation speed sensor 70, and even the temperature sensor or the camera, the survey device proposed in this scheme has a limited size, and the length of its support assembly 40 can be adapted to change as needed. Therefore, the overall installation is susceptible to swaying in strong winds. The transmission module 23 of the pneumatic assembly 20 cooperates with the support assembly 40 for support, so that it can avoid swaying at a certain height.

[0049] The side wall of the base assembly 12 is installed with a plurality of pneumatic assemblies 20 that are in transmission cooperation with the electric control box 11. The pneumatic assemblies 20 include a first pneumatic module 21 fixed to the side wall of the base assembly 12 and a second pneumatic module 22 sliding thereon. The surfaces of the first pneumatic module 21 and the second pneumatic module 22 are jointly provided with a transmission module 23. The pneumatic assemblies 20 drive the base assembly 12 to rotate partially by wind force and cooperate with the speed sensor 70 to detect the wind speed.

[0050] The pneumatic component 20 can not only change the centrifugal force of its counterweight sleeve 224 with the rotation speed, and thereby provide power for the normal use of the cleaning component 30 and the cutter 215, but also can adjust the height and the windward surface of the wind shield 222 under different wind forces to a certain extent, thereby providing a guarantee for long-term endurance.

[0051] In a light wind state, the rotating cutter 215 suppresses the growth of grass leaves at a relatively close distance. In a strong wind state, as the height of the electric control box 11 is lowered, the cutter 215 also drops in height in sync with the overall height drop, and can rely on a relatively high wind speed to provide sufficient kinetic energy to cut the grass leaves nearby below, while also cutting the fallen grass leaves, thereby preventing the bottom layer of lighting from being covered by weeds when installed on the ground.

[0052] The swinging cutter 215 can drive away animals, and the rotating wind shield 222 can prevent birds from landing, thereby preventing the light detection from being affected by the approach of living things.

[0053] When the wind speed does not exceed the threshold, the cleaning component 30 is driven by the pneumatic component 20 through the base component 12 and cleans the glass cover 13. At the same time, the first pneumatic module 21 hits and pushes away the nearby plants. When the wind speed exceeds the threshold, the transmission module 23 controls the support component 40 to lower the electrical control box 11 to a wind-resistant height. The first pneumatic module 21 cuts the plants. At the same time, the second pneumatic module 22 automatically adjusts the inclination angle as the wind force increases to balance the rotation speed.

[0054] Specifically, Figure 4 and Figure 5 As shown: the electric control box 11 includes a box body 111 fixed at the top of the support assembly 40, and a transfer cover 112 is installed on the top of the box body 111 to match the base assembly 12. The surface of the box body 111 is vertically slidable with a fixed wheel 113 for matching the transmission of the first pneumatic module 21. The box body 111 of the electric control box 11 is equipped with electronic equipment such as a power supply and a main control board, and the transfer cover 112 can close the top of the box body 111 and keep the box body 111 connected to the transfer seat 121. Specifically, as shown in FIG. Figure 5 As shown: the base assembly 12 includes an adapter seat 121 fixed on the inner wall of the adapter cover 112, a rotating seat 122 is installed on the adapter seat 121 through a bearing, the glass cover 13 is fixedly connected to the rotating seat 122, and the inner wall of the adapter seat 121 is threadedly matched with a sealing seat 123, and the upper surfaces of the sealing seat 123 and the adapter seat 121 are jointly provided with a partition frame 124, the surface of the partition frame 124 is provided with a photovoltaic panel 60, and the light detector 50 is arranged through the surface of the sealing seat 123, the adapter seat 121 is installed on the surface of the box body 111 through the adapter cover 112, maintains support, and supports the rotating seat 122 to rotate through the bearing, and the rotating seat 122 rotates with the glass cover 13 at the same time.

[0055] Specifically, Figure 1 , Figure 2 , Figure 8 , Figure 6 and Figure 7 As shown: the cleaning assembly 30 includes an arc-shaped inner frame 31 and an arc-shaped outer frame 33 located on the inner and outer sides of the glass cover 13, and the tops of the arc-shaped inner frame 31 and the arc-shaped outer frame 33 are jointly fixed with a bearing seat 32, the bearing seat 32 penetrates and rotates on the top of the glass cover 13, and the inner wall of the bearing seat 32 and the bottom end of the arc-shaped outer frame 33 are jointly rotated and installed with an elastic brush 35, and the surface of the arc-shaped outer frame 33 is provided with self-cleaning bristles 37 for cleaning the elastic brush 35, and the bottom end of the elastic brush 35 is fixedly connected with a transmission wheel 36, and the transmission wheel 36 is transmission-coordinated with the side wall of the rotating seat 122, and a rubber strip 34 is provided on the surface of the arc-shaped inner frame 31.

[0056] The surface of the arc-shaped inner frame 31 is scraped against the inner wall of the glass cover 13 by the rubber strip 34, which can clean the internal water mist under the temperature difference and guide the water body to the bottom of the partition frame 124 and flow out through the gap between the adapter seat 121 and the rotating seat 122, so as to realize sunlight detection in the morning, avoid fog blocking the sunlight and causing inaccurate detection, and avoid water vapor gathering in the glass cover 13;

[0057] At the same time, the transmission wheel 36 is in a fixed position. When the rotating seat 122 rotates, the transmission wheel 36 rotates with it. The transmission wheel 36 carries the elastic brush 35 to fit the surface of the glass cover 13. When the elastic brush 35 rotates, it cooperates with the moving glass cover 13 to evenly clean the surface. At the same time, the self-cleaning bristles 37 on the inner wall of the arc-shaped outer frame 33 can tidy up the elastic brush 35 to ensure that the elastic brush 35 keeps the bristles loose during long-term use to avoid knotting or adhesion and accumulation of dirt.

[0058] Specifically, Figure 2 and Figure 4 As shown, the support assembly 40 includes a vertical tube 41 fixed to the bottom of the electric control box 11, a column 42 is slidably provided on the inner wall of the vertical tube 41, a retaining frame 43 is fixed on the surface of the column 42, and a plurality of ground nails 44 penetrate the surface of the retaining frame 43. The column 42 can be supported by the vertical cylinder 41 to slide inside, wherein the column 42 always cooperates with the vertical cylinder 41 to reach the maximum length. The supporting force is applied to the tension spring 232 by the support plate 234 and the auxiliary support plate 233. The elasticity of multiple tension springs 232 keeps the column 42 always in a state of sliding out of the vertical cylinder 41, so that when the counterweight sleeve 224 gradually increases with the centrifugal force and stretches the tension spring 232, the counterweight sleeve 224 moves, the second pressure plate 231 moves, and the angle between the support plate 234 and the auxiliary support plate 233 decreases. Then, the support distance of the bottom end of the support plate 234 to the column 42 through the second rotation node 242 changes, and the column 42 synchronously slides into the vertical cylinder 41 to reduce its length.

[0059] Specifically, the pneumatic assembly 20 further includes a support node 24 , and the support node 24 includes a first rotation node 241 and a second rotation node 242 rotatably connected to the first pneumatic module 21 and the surface of the column 42 .

[0060] The first rotation node 241 is rotatably connected to the surface of the guide rod 213, so that the first pressure plate 216 can press the first rotation node 241 to move and keep the guide rod 213 rotating when the counterweight sleeve 224 moves.

[0061] Specifically, Fig.10As shown: the first pneumatic module 21 includes a support rod 211 fixedly connected to the side wall of the rotating seat 122, the other end of the support rod 211 is fixedly connected to a support cover 212, the surface of the support cover 212 is penetrated by a guide rod 213 that slides, the bottom end of the guide rod 213 is fixedly connected to a cutter 215, the surface of the guide rod 213 is fixedly connected to a moving wheel 214, the moving wheel 214 is connected to the fixed wheel 113 through a belt, the first rotating node 241 is rotatably installed on the surface of the guide rod 213, and the first pneumatic module 21 also includes a first pressure plate 216 movably connected to the first rotating node 241 through a pin shaft.

[0062] The support rod 211 of the first pneumatic module 21 is a rigid support for the entire pneumatic module, and the support rod 211 keeps the support cover 212 fixed so that the support cover 212 can always remain vertical to the guide rod 213, and the deflection of the wind cover 222 will not affect the support cover 212 and the guide rod 213.

[0063] When the pneumatic assembly 20 starts to rotate with the rotating seat 122 under the action of wind, the driving wheel 214 on the surface of the guide rod 213 revolves simultaneously. The rotating driving wheel 214 interacts with the relatively non-rotating driving wheel 214 through the belt, so that the driving wheel 214 revolves and rotates at the same time, thereby realizing the rotation of the guide rod 213.

[0064] Under the action of ambient wind, the grass blades will swing. Under the action of low-speed wind, the cutter 215 that revolves clockwise and rotates counterclockwise synchronously can push away the grass blades that are swinging at a relatively close distance, and can suppress the vertical height growth of the grass blades to a certain extent at the installation position. When a strong wind blows, the counterweight sleeve 224 presses down the first rotation node 241 through the first pressure plate 216, and the first rotation node 241 keeps the guide rod 213 from rotating when it is pressed down. When the guide rod 213 moves downward, it slides in the guide groove 80 through the driving wheel 214 and the belt with the fixed wheel 113, and keeps the cutter 215 rotating continuously when the guide rod 213 moves downward. Under the condition that the driving wheel 214 is sufficient provided by the strong wind, the cutter 215 in a fast-revolving and highly rotating state can cut and trim the grass blades in the installation area when it moves downward, and at the same time cut the grass blades that are lying and blocked in the nearby area. Under long-term installation, it not only ensures that it will not be submerged by weeds, but also avoids being covered by the lying grass blades.

[0065] Since the grass leaves are in a swinging state under strong wind, the swinging amplitudes are different under different wind forces. Therefore, when the cutter 215 is completely blocked, it can still rotate again when the fallen grass leaves leave, and gradually achieve the cutting effect.

[0066] Specifically, Fig.11As shown: the second pneumatic module 22 includes a slide 221 slidably set on the surface of the support rod 211, one end of the slide 221 is fixedly connected to a wind cover 222, the wind cover 222 slides on the surface of the support cover 212, the arc-shaped side wall of the slide 221 is provided with a slide groove 223 which gradually transitions from straight to inclined, the surface of the slide 221 is slidably set with a counterweight sleeve 224, and the inner wall of the counterweight sleeve 224 is provided with a protrusion 225 that slides in the slide groove 223 with a limited position.

[0067] The wind cover 222 of the second pneumatic module 22 can play a good role in facing the wind and maintain a good airflow driving force. The wind cover 222 is fixed to the wind cylinder and can apply a force to the rotating seat 122 through the support rod 211. At the same time, the slide groove 223 on the surface of the slide cylinder 221 can cooperate with the convex point 225 on the inner wall of the counterweight sleeve 224. The counterweight sleeve 224 is supported by the first pressure plate 216, the guide rod 213 and the support cover 212 in the reverse direction, so that it can only move axially and cannot rotate. During the axial movement, the convex point 225 and the slide groove 223 cooperate to provide the slide cylinder 221 with a deflecting torque, so that the slide cylinder 221 can deflect with the wind cover 222. On the contrary, when the counterweight cylinder is not displaced, the convex point 225 limits the slide groove 223 to keep the slide cylinder 221 from deflecting.

[0068] Specifically, Figure 4 Fig.10 and Fig.12 As shown: the transmission module 23 includes a second pressure plate 231, an auxiliary support plate 233 and a support plate 234 which are movably connected at one opposite end through a pin, the auxiliary support plate 233 is movably connected to the side wall of the rotating seat 122 through a pin, the bottom end of the support plate 234 is movably connected to the second rotation node 242 on the surface of the support assembly 40 through a pin, and also includes a tension spring 232 fixedly connected to one side of the counterweight sleeve 224, and the second pressure plate 231 is movably connected to the surface of the counterweight sleeve 224 at one end opposite to the first pressure plate 216 through a pin.

[0069] A triangular support structure is formed by setting an auxiliary support plate 233 and a support plate 234, wherein one end of the auxiliary support plate 233 is movably connected to the surface of the rotating seat 122 through a pin, and the bottom end of the support plate 234 is movably connected to the second rotation node 242 through a pin, and the second rotation node 242 is rotatably supported on the surface of the column 42, and the opposite ends of the auxiliary support plate 233 and the support plate 234 are movably connected to the bottom end of the second pressure plate 231 through a pin. When the counterweight sleeve 224 moves, the top end of the second pressure plate 231 moves, so that the pressing position of the bottom end of the second pressure plate 231 on the opposite end of the auxiliary support plate 233 and the support plate 234 changes, and the angle between the auxiliary support plate 233 and the support plate 234 changes, so that the distance between the auxiliary support plate 233 and the support plate 234 changes, thereby realizing the telescopic control of the vertical tube 41 and the column 42, and adjusting the overall height.

[0070] The surface of the box body 111 is provided with a plurality of guide grooves 80 for sliding in cooperation with the fixed wheel 113. The setting of the guide grooves 80 can keep the fixed wheel 113 sliding in cooperation. The guide wheel cannot slide under the limit of the guide grooves 80, but the moving wheel 214 can slide vertically. When the moving wheel 214 moves vertically with the guide rod 213, under the action of the transmission belt, the moving wheel 214 can also slide vertically in cooperation.

[0071] During installation of this solution, the cleaning assembly 30 is oriented toward the north and the column 42 is vertically inserted into the ground, and the column 42 is continuously inserted until the retaining frame 43 contacts the ground, and then the ground nail 44 is passed through the retaining frame 43 and driven into the ground to complete the installation;

[0072] After installation, as the breeze blows, the wind cover 222 rotates with the rotating seat 122 through the wind tube and the support rod 211, and the rotating seat 122 drives the elastic brush 35 to rotate and rotates the glass cover 13 at the same time. When the elastic brush 35 rotates, the surface of the rotating glass cover 13 is continuously and evenly cleaned;

[0073] Sunlight passes through the glass cover 13 and falls on the photovoltaic panel 60 and the light detector 50, which generates electricity while accurately detecting the light. At the same time, the speed sensor 70 detects the speed of the rotating seat 122 to detect the wind speed.

[0074] This solution can quickly provide early warning of forest fires when light is detected at night.

[0075] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
