Description

Technical Field

[0001] The present invention relates to the technical field of forestry management, and particularly relates to a measuring device for forestry survey planning and design. Background Art

[0002] Forestry planning and design can formulate protection plans for specific forest resources, such as nature reserves, forest parks, and ecological public welfare forests, etc., to ensure the reasonable protection and sustainable utilization of these resources. Through forestry surveys, the quantity, quality, distribution, and utilization status of forest resources can be comprehensively and accurately grasped, providing a scientific basis for formulating forest resource management policies, plans, and protection measures.

[0003] In forestry survey planning and design, the selection of the measuring device is crucial, which is directly related to the accuracy and reliability of the survey results. In the existing forestry survey planning and design technology, the operator uses the measuring device to conduct on-site surveys to obtain forest resource data, such as forest type, tree species structure, and growth status, etc. However, due to the rough road surface in the forest for the existing measuring devices in the prior art, the existing measuring devices often lack a suitable measuring angle and require manual assistance from the operator to carry out the measurement, resulting in low measurement efficiency and poor convenience.

[0004] In summary, how to solve the problem that the existing measuring devices in the prior art often lack a suitable measuring angle due to the rough road surface in the forest and require manual assistance from the operator to carry out the measurement, resulting in low measurement efficiency and poor convenience has become a difficult problem that urgently needs to be solved in the current field. Therefore, it is necessary to propose a convenient measuring device for forestry survey planning and design. Summary of the Invention

[0005] To solve the above problems, the present invention provides a measuring device for forestry survey planning and design. Through the structural design of the base and the measuring box, the measuring height of the measuring device can be adjusted according to the actual situation of the measurement target; through the design of the angle adjustment component, the measuring angle of the measuring device can be adjusted according to the actual situation of the forest ground; and through the design of the lever, the actual angle of the whole device can be monitored in real time, and the height and angle of the measuring box can be adjusted based on this.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A measuring device for forestry investigation and planning design includes a measuring device, a base, and a controller. A vertical groove is provided on the side wall of the base. A slider is slidably fitted in the vertical groove. A measuring box is hinged to the side wall of the slider. The measuring device is fixedly installed in the measuring box. An angle adjustment assembly is provided between the measuring box and the slider for adjusting the angle of the measuring box. A hinged rod is hinged to the top of the slider. The top end of the hinged rod is hinged to a lever. A horizontal groove is provided on the top of the base. A first driving member is embedded in the horizontal groove. The output shaft of the first driving member is coaxially fixedly connected to a lead screw. A nut seat is in threaded cooperation with the lead screw. The lead screw and the nut seat are respectively rotatably and slidably fitted with the horizontal groove. The controller is used to control the rotation of the output shaft of the first driving member, thereby driving the lead screw to rotate and adjusting the position of the nut seat. A support rod is fixedly connected to the upper side wall of the nut seat. A chute is provided on the lever. The support rod is slidably fitted with the chute. A driving assembly for adjusting the angle of the lever and the height of the measuring box is provided at one end of the lever away from the hinged rod. An angle sensor is embedded in the lever. The controller is used to receive the angle value collected by the angle sensor and control the driving assembly to adjust the angle of the lever based on the angle value.

[0007] A protective assembly for protecting the measuring device, a moving assembly for driving the measuring device to move, and an auxiliary assembly for assisting the measuring device in measurement are provided outside the base.

[0008] The technical principle of the above solution is as follows:

[0009] When the device works on the rugged forest ground, the angle of the lever changes with the change of the slope. At this time, the angle collected by the angle sensor is the slope of the forest. After measuring the current slope, the controller is used to adjust the driving assembly to adjust the height of the adjusting limiting rod, and then adjust the height of the side of the lever away from the hinged rod. Due to the supporting effect of the support rod, combined with the movement of the lever away from, the height of the side of the lever close to the hinged rod will also change accordingly, and then adjust the height of the hinged rod, thereby adjusting the height of the measuring box; when the tree is tall, the height of the measuring device is increased; when the tree is short, the height of the measuring device is lowered; so that the measuring device can measure from different heights. The first driving member drives the lead screw to rotate, thereby adjusting the positions of the nut seat and the support rod, and then adjusting the movement amplitude of the lever to expand the height adjustment range of the measuring device.

[0010] By using the measuring device to measure the angle between the tree and the current forest ground, and combining the slope of the current forest ground measured by the angle sensor, the angle between the tree and the horizontal ground can be calculated, and then the inclination angle of each tree can be accurately judged; and then according to the slope of the measurement target and the current forest ground, the angle adjustment assembly is adjusted to make the measuring device parallel to the measurement target, so as to obtain accurate tree height, tree diameter and tree shape.

[0011] The beneficial effects of adopting the above solution are as follows:

[0012] 1. By installing an angle sensor on the lever, the present invention can monitor the slope of the forest ground in real time, and accordingly adjust the angle of the lever and the height of the measuring box, enabling the measuring device to automatically adapt to terrains with different slopes and measuring targets at different heights, effectively improving the flexibility and adaptability of the measuring device during measurement, and at the same time reducing the measurement errors caused by uneven terrain. For the measuring devices in the prior art, due to the rugged forest ground, manual angle adjustment and height adjustment are required to perform accurate measurements. Compared with the prior art, the present invention is more efficient and convenient, and can automatically adjust the angle of the lever and the height of the measuring box according to the conditions of the forest road surface.

[0013] 2. Compared with installing the angle sensor on a fixed base, the present invention takes advantage of the fact that the lever is easy to rotate and can adjust its own angle, and installs the angle sensor on the lever, which is convenient for zeroing the angle sensor. If the angle sensor is installed on a fixed base, when there are defects such as deformation or uneven machining of the base, it is impossible to quickly adjust the detection angle of the angle sensor, which is not convenient for zeroing operation; if adjustment is required, steps such as disassembling, adjusting, reassembling and installing the angle sensor are needed, and the process is complex, thus greatly reducing the convenience and efficiency of forestry surveys.

[0014] 3. Through the design of the angle adjustment component, the present invention combines the angle of the forest ground measured by the angle sensor to adjust the angle of the measuring device in real time, so that the measuring device is parallel to the tree, and then accurately collects various data of the tree, improving the accuracy and intelligent level of forestry surveys, without the need for operators to provide manual assistance, greatly reducing the labor cost and improving the convenience of forestry surveys.

[0015] 4. By using the design of the lead screw and the nut seat, when using the lever to adjust the measuring height of the measuring device, the position of the support rod can be quickly adjusted, and then the position of the lever fulcrum can be adjusted. Since the lever rotates around the fulcrum, when the support rod is closer to the drive component, the rotation radius of the lever is larger, and the rotation amplitude of the lever on the side close to the hinge rod is larger; on the contrary, the rotation amplitude of the lever on the side close to the hinge rod is smaller, thus realizing the adjustment of different heights of the measuring box. Compared with the prior art, the present invention utilizes the characteristic that the lever can rotate by itself, combines the design of the hinge rod, converts the force of the lever rotation into a vertical pulling force, and then drives the measuring box to move up and down without the need to additionally increase other power, greatly reducing the manufacturing cost and maintenance cost, and effectively reducing the economic consumption of forestry surveys.

[0016] Furthermore, the driving component includes a bracket fixedly connected to the top of the base. A rotating rod is rotatably connected to the side wall of the bracket, and one end of the rotating rod away from the bracket is hinged to the side wall of the lever. A second driving member is also fixedly connected to the top of the base. An eccentric wheel is eccentrically fixedly connected to the output shaft of the second driving member. A rotating groove is formed in the eccentric wheel. An adjusting rod is fixedly connected to the side wall of the lever close to the eccentric wheel, and the adjusting rod is slidably engaged with the rotating groove. The controller is used to control the rotation of the output shaft of the second driving member, thereby driving the eccentric wheel to rotate to adjust the height of the adjusting rod, so as to adjust the angle of the lever and the height of the measuring device.

[0017] Beneficial effects: By starting the output shaft of the second driving member to rotate clockwise through the controller, the output shaft of the second driving member drives the eccentric wheel to deflect clockwise. When the eccentric wheel rotates upward, the rotating groove will exert an upward extrusion on the adjusting rod during the rotation process, thereby raising the height of the adjusting rod. As a result, the height of the end of the lever fixed to the adjusting rod is lifted. Due to the supporting effect of the support rod and in combination with the lever principle, the height of the end of the lever close to the hinge rod will decrease, thereby pushing the hinge rod downward, and the hinge rod pushes the measuring device downward. When the eccentric wheel rotates downward, the rotating groove will exert a downward extrusion on the adjusting rod during the rotation process, thereby reducing the height of the adjusting rod. As a result, the height of the end of the lever fixed to the adjusting rod decreases, while the height of the end of the lever close to the hinge rod will increase, thereby pushing the hinge rod upward, and the hinge rod pushes the measuring device upward.

[0018] Furthermore, the protection component includes a protection box, and an observation port is formed in the side wall of the protection box. A rotating component for adjusting the angle of the protection box is provided at the bottom of the protection box.

[0019] Beneficial effects: Since the environment in the forest is relatively complex, the protection box can wrap various components and the measuring device, providing protection effects such as wind prevention, waterproofing, and dust prevention. At the same time, it also prevents sundries from entering and affecting the operation of various components, improving the stability of the device operation.

[0020] Furthermore, the rotating component includes a rotating table rotatably connected to the bottom of the protection box. A third driving member is embedded in the rotating table, and the output shaft of the third driving member is embedded in the bottom of the protection box and fixedly connected thereto. The controller is used to control the rotation of the output shaft of the third driving member, thereby adjusting the angle of the protection box.

[0021] Beneficial effects: By starting the output shaft of the third driving member to rotate through the controller, the protection box is driven to rotate, thereby adjusting the measuring orientation of the measuring device; effectively improving the measuring range of the measuring device and enhancing the comprehensiveness and convenience of forestry surveys.

[0022] Furthermore, the moving component includes crawler wheels rotatably fitted to the bottom of the rotating table. The controller is used to control the operation of the crawler wheels, thereby driving the overall movement of the device.

[0023] Beneficial effects: Since the environment of the woods is complex and the road surface is rough, a crawler wheel is selected to drive the whole device to move, which can better adapt to the environment of the woods.

[0024] Furthermore, the auxiliary component includes a plurality of infrared rangefinders fixedly connected to the side wall of the protective box; the plurality of infrared rangefinders are distributed on the upper and lower sides of the observation port; the controller is used to control the opening and closing of the infrared rangefinders, and then measure the distance and relative angle between the protective box and the measurement target.

[0025] Beneficial effects: The infrared rangefinders are arranged on the upper and lower sides of the observation port. The controller emits infrared light to the measurement target. The infrared rangefinder calculates the distance to the measurement target according to the time taken for the infrared light to reflect. Then, based on the distance difference measured by the upper and lower infrared rangefinders and combined with the height difference between the upper and lower infrared rangefinders, through the Pythagorean theorem and the cosine theorem, the angle between the measurement target and the horizontal plane can be calculated. Then, combined with the ground slope measured by the angle sensor, the inclination of the tree can be calculated; by using several groups of infrared rangefinders for segmented and grouped calculations, the approximate curve of the tree can be calculated and the shape curve of the tree can be drawn.

[0026] Furthermore, the angle adjustment component includes a telescopic rod. The telescopic rod is fixedly connected to the side wall of the measurement box close to the slider, and the output shaft of the telescopic rod is hinged to the side wall of the slider close to the measurement box; the controller is used to control the operation of the telescopic rod, and then adjust the angle of the measurement box.

[0027] Beneficial effects: By adjusting the output distance of the telescopic rod through the controller, the telescopic rod will push the measurement box to rotate. Combined with the angle of the woods ground measured by the angle sensor, the output distance of the telescopic rod is controlled, and then the angle of the measuring device is adjusted in real time, so that the measuring device is parallel to the tree, and then various data of the tree can be accurately collected.

[0028] Furthermore, an eccentric groove for the eccentric wheel to rotate is opened at the top of the base.

[0029] Beneficial effects: The design of the eccentric groove enables the eccentric wheel to rotate normally without adjusting the installation height, and there will be no collision with the base; since the eccentric wheel generates vibration during rotation, a higher height will increase the influence of the vibration. Compared with the method of installing by increasing the installation height of the eccentric wheel, the design of the eccentric groove is simpler and more convenient, and has higher stability.

[0030] Furthermore, a transparent cover plate is hinged at the observation port.

[0031] Beneficial effects: The transparent cover plate protects the measuring device while not affecting the measurement of the measuring device; at the same time, it is also convenient for the operator to perform subsequent inspections and maintenance.

[0032] Furthermore, both the vertical groove and the slider are trapezoidal.

[0033] Beneficial effects: The trapezoidal vertical groove and the slider can effectively prevent the slider from falling off the vertical groove.

[0034] The additional aspects and advantages of the present invention will be partially given in the following description, partially become apparent from the following description, or be understood through the practice of the present invention. Brief Description of the Drawings

Detailed Description of the Specific Embodiment

[0039] The following is a further detailed description through specific embodiments:

[0040] Embodiment 1:

[0041] As Figure 1As shown in the figure, a measuring device for forestry survey planning and design includes a measuring device, a base 2 and a controller. A vertical groove is formed in the side wall of the base 2, and a slider 3 is slidably fitted in the vertical groove. A measuring box 4 is hinged to the side wall of the slider 3, and the measuring device is fixedly connected to the measuring box 4 by bolts. An angle adjusting assembly is provided between the measuring box 4 and the slider 3 for adjusting the angle of the measuring box 4. A hinged rod 5 is hinged to the top of the slider 3, and the top end of the hinged rod 5 is hinged to a lever 6. A horizontal groove is formed in the top of the base 2, and a first driving member is embedded in the horizontal groove. The output shaft of the first driving member is coaxially and fixedly connected to a lead screw 7 by bolts. A nut seat 8 is in threaded fit with the lead screw 7, and the lead screw 7 and the nut seat 8 are respectively in rotational fit and sliding fit with the horizontal groove. The controller is used to control the rotation of the output shaft of the first driving member, thereby driving the rotation of the lead screw 7, and thus adjusting the position of the nut seat 8. A support rod 9 is welded to the upper side wall of the nut seat 8, and a chute is formed in the lever 6, and the support rod 9 is slidably fitted with the chute. A driving assembly is provided at one end of the lever 6 away from the hinged rod 5 for adjusting the angle of the lever 6 and the height of the measuring box 4. An angle sensor is embedded in the lever 6. The controller is used to receive the angle value collected by the angle sensor and control the driving assembly to adjust the angle of the lever 6 based on the angle value.

[0042] The driving assembly includes a bracket 10 welded to the top of the base 2. A rotating rod 11 is rotatably connected to the side wall of the bracket 10, and the end of the rotating rod 11 away from the bracket 10 is hinged to the side wall of the lever 6. A second driving member is fixedly connected to the top of the base 2 by bolts. An eccentric wheel 14 is eccentrically and fixedly connected to the output shaft of the second driving member. A rotating groove is formed in the eccentric wheel 14, and an adjusting rod 12 is welded to the side wall of the lever 6 close to the eccentric wheel 14. The adjusting rod 12 is slidably fitted with the rotating groove. The controller is used to control the rotation of the output shaft of the second driving member, thereby driving the rotation of the eccentric wheel 14 to adjust the height of the adjusting rod 12, and thus adjusting the angle of the lever 6 and the height of the measuring device.

[0043] A protection assembly for protecting the measuring device, a moving assembly for driving the measuring device to move, and an auxiliary assembly for assisting the measuring device to perform measurements are provided outside the base 2.

[0044] The protection assembly includes a protection box 1, and an observation port is formed in the side wall of the protection box 1. A rotating assembly for adjusting the angle of the protection box 1 is provided at the bottom of the protection box 1. Since the environment in the forest is relatively complex, the protection box 1 can wrap various components and the measuring device, providing protection effects such as wind prevention, waterproofing, and dust prevention. At the same time, it also prevents sundries from entering and affecting the operation of various components, improving the stability of the device operation. The design of the observation port enables the protection box 1 not to block the field of view of the measuring device.

[0045] The rotating assembly includes a rotating table 18 rotatably connected to the bottom of the protection box 1. A third driving member is embedded in the rotating table 18, and the output shaft of the third driving member is embedded in the bottom of the protection box 1 and fixedly connected to it by bolts. The controller is used to control the rotation of the output shaft of the third driving member, thereby adjusting the angle of the protection box 1. During the measurement process, the operator controls the rotation of the output shaft of the third driving member through the controller, thereby driving the rotation of the protection box 1, so as to adjust the measurement orientation of the measuring device, which can effectively increase the measurement range of the measuring device and improve the comprehensiveness and convenience of forestry surveys.

[0046] The moving assembly includes crawler wheels 16 rotatably fitted to the bottom of the rotating table 18. The controller is used to control the operation of the crawler wheels 16, thereby driving the overall movement of the device. Due to the complex forest environment and rough road surface, the crawler wheels 16 are selected to drive the overall movement of the device, which can better adapt to the forest environment.

[0047] The auxiliary assembly includes a number of infrared rangefinders 17 fixedly connected to the side wall of the protection box 1 by screws. The infrared rangefinders 17 are evenly distributed on both sides of the observation port above and below. The controller is used to control the opening and closing of the infrared rangefinders 17, thereby measuring the distance and relative angle between the protection box 1 and the measurement target.

[0048] As Figure 3 shown, the angle adjustment assembly includes a telescopic rod 15. The telescopic rod 15 is fixedly connected to the left side wall of the measurement box 4 by bolts, and the output shaft of the telescopic rod 15 is hinged to the right side wall of the slider 3. The controller is used to control the operation of the telescopic rod 15, thereby adjusting the angle of the measurement box 4.

[0049] In this embodiment, the first driving member, the second driving member, and the third driving member are respectively selected as the first motor, the second motor 13, and the third motor 19.

[0050] The specific implementation process is as follows:

[0051] In this embodiment, the measuring device is a lidar. The lidar measures the three-dimensional structure of the ground and trees by emitting laser beams to the ground and receiving the reflected signals, and can accurately obtain key parameters such as tree height, crown width, and stand density.

[0052] As Figure 1As shown, when on a horizontal ground, the lever 6 is horizontal with the ground, and the nut seat 8 is at the leftmost side of the transverse groove. At this time, the angle value measured by the angle sensor is 0. If the angle value measured by the angle sensor is not 0 at this time, the controller will perform a zero adjustment operation. During this process, the controller controls the output shaft of the second motor 13 to rotate clockwise, and the output shaft of the second motor 13 drives the eccentric wheel 14 to deflect clockwise; when the eccentric wheel 14 rotates, the adjusting rod 12 will be limited by the rotating groove, and thus slide up and down in the rotating groove along with the rotation of the eccentric wheel 14, thereby adjusting the angle of the lever 6, making the angle value measured by the angle sensor return to 0, so as to realize the zero adjustment operation of the angle sensor and ensure the accuracy of subsequent measurements.

[0053] After the zero adjustment operation is completed, the measurement work can begin. Taking Figure 2 as an example, the operator controls the crawler wheels 16 to move through the controller, so that the lidar enters the measurement range and measures the trees in the target area. At this time, the angle of the lever 6 will change with the change of the slope, and the angle collected by the angle sensor at this time is the slope of the forest ground.

[0054] Then, the controller controls the infrared rangefinder 17 to emit infrared light towards the measurement target. The infrared rangefinder 17 will calculate the distance to the measurement target according to the time taken for the infrared light to reflect. Then, according to the distance difference measured by the upper and lower infrared rangefinders 17 and combining the height difference between the upper and lower infrared rangefinders 17, through the Pythagorean theorem and the cosine theorem, the angle between the measurement target and the horizontal plane can be calculated. Combining with the ground slope measured by the angle sensor, the inclination of the tree can be calculated; by using several groups of infrared rangefinders 17 and performing segmented and grouped calculations, the approximate angles at various places of the tree can be calculated, thereby drawing the shape curve of the tree.

[0055] At this time, the operator has quickly collected the ground slope of the forest, the angle between the measurement target and the horizontal plane, and the angle between the measurement target and the forest ground slope. The controller will automatically adjust the output distance of the telescopic rod 15 according to the slope of the measurement target and the current forest ground, and then adjust the laser emission angle of the lidar, so that the laser beam emitted by the lidar is parallel to the measurement target, and then obtain accurate data such as the height, diameter, and shape of the tree.

[0056] Taking Figure 1For example, during the measurement process, the controller also adjusts the height of the lidar according to the occlusion situation, light condition, and tree height of the acquisition environment, etc., in order to reduce obstacle occlusion, adapt to trees of different heights, and collect more accurate data. During this process, the controller controls the output shaft of the second motor 13 to rotate clockwise again, and the output shaft of the second motor 13 drives the eccentric wheel 14 to deflect clockwise; when the protruding end of the eccentric wheel 14 rotates upward, during the rotation of the rotating groove, the protruding end of the eccentric wheel 14 will exert an upward lifting effect on the adjusting rod 12, thereby raising the height of the adjusting rod 12, so that the height of the end of the lever 6 fixed to the adjusting rod 12 is lifted. Due to the supporting effect of the support rod 9 and the lever principle, the height of the end of the lever 6 close to the articulated rod 5 will decrease, thereby pushing the articulated rod 5 downward. Since the articulated rod 5 is articulated with the slider 3 and the slider 3 is slidably matched with the vertical groove, the articulated rod 5 will push the slider 3 downward. And since the slider 3 is fixed to the measurement box 4, the measurement box 4 and the lidar will move downward together with the slider 3; conversely, when the protruding end of the eccentric wheel 14 rotates downward, the adjusting rod 12 loses the upward lifting effect of the protruding end of the eccentric wheel 14, and then moves downward, thereby reducing the height of the adjusting rod 12, so that the height of the end of the lever 6 fixed to the adjusting rod 12 decreases, while the height of the end of the lever 6 close to the articulated rod 5 will rise, thereby pulling the articulated rod 5 upward, and then pulling the lidar upward.

[0057] The above process realizes the free adjustment of the height of the lidar. When the tree is taller, the height of the lidar is increased; when the tree is shorter, the height of the lidar is lowered; so that the lidar can measure from different heights, adjust the measurement range, thereby adapting to trees of different heights, finding a more reasonable measurement position, and improving the measurement accuracy.

[0058] During the height adjustment process, the operator controls the rotation of the output shaft of the first motor through the controller, drives the lead screw 7 to rotate, and then adjusts the positions of the nut seat 8 and the support rod 9. Since the support rod 9 serves as a fulcrum during the movement of the lever 6 and provides support for the lever 6, and the lever 6 rotates around the support rod 9, therefore, when the support rod 9 is closer to the right side of the horizontal groove, the rotation radius of the lever 6 is larger, the rotation amplitude on the left side of the lever 6 is larger, and the height adjustment range of the measurement box 4 is larger; conversely, when the support rod 9 is closer to the left side of the horizontal groove, the rotation amplitude on the left side of the lever 6 is smaller, and the height adjustment range of the measurement box 4 is smaller; thus realizing the adjustment of different heights of the measurement box 4 and further improving the measurement accuracy.

[0059] By installing an angle sensor on the lever 6, the present invention can monitor the slope of the forest ground in real time, and accordingly adjust the angle of the lever 6 and the height of the measuring box 4, enabling the lidar to automatically adapt to terrains with different slopes and measuring targets at different heights, effectively improving the flexibility and adaptability of the lidar during measurement, and at the same time reducing the measurement errors caused by uneven terrain. For the lidar in the prior art, due to the rugged forest ground, manual angle adjustment and height adjustment are required to perform accurate measurement. Compared with the prior art, the present invention is more efficient and convenient, and can automatically adjust the angle of the lever 6 and the height of the measuring box 4 according to the conditions of the forest road surface.

[0060] Compared with installing the angle sensor on the base 2, the present invention takes advantage of the fact that the lever 6 is easy to rotate and can adjust its own angle, and installs the angle sensor on the lever 6, which is convenient for zeroing the angle sensor. If the angle sensor is installed on the base 2 with a fixed position, when there are defects such as deformation or uneven machining of the base 2, it is impossible to quickly adjust the detection angle of the angle sensor, which is not convenient for zeroing operation; if adjustment is required, steps such as disassembling, adjusting, reassembling and installing the angle sensor are needed, and the process is complex, thus greatly reducing the convenience and efficiency of forestry surveys.

[0061] Through the design of the telescopic rod 15, combined with the angle of the forest ground measured by the angle sensor, the angle of the lidar can be adjusted in real time, so that the lidar is parallel to the trees, and then various data of the trees can be accurately collected, improving the accuracy and intelligent level of forestry surveys, without the need for operators to provide manual assistance, greatly reducing the labor cost and improving the convenience of forestry surveys.

[0062] By using the design of the screw rod 7 and the nut seat 8, when using the lever 6 to adjust the measurement height of the lidar, the position of the support rod 9 can be quickly adjusted, and then the position of the fulcrum of the lever 6 can be adjusted to realize the adjustment of different heights of the measuring box 4. Compared with the prior art, the present invention takes advantage of the characteristic that the lever 6 can rotate itself, combined with the design of the articulated rod 5, to convert the rotational force of the lever 6 into a vertical pulling force, thereby driving the measuring box 4 to move up and down without the need to additionally increase other power, greatly reducing the manufacturing cost and maintenance cost, and effectively reducing the economic consumption of forestry surveys.

[0063] Embodiment 2:

[0064] As Figure 1 shown, the difference from the above embodiment is that an eccentric groove for the rotation of the eccentric wheel 14 is opened at the top of the base 2.

[0065] The specific implementation process is as follows: The design of the eccentric groove enables the eccentric rotation to be carried out normally without adjusting the installation height of the eccentric wheel 14, and there will be no collision with the base 2; Since the eccentric wheel 14 generates vibration during rotation, a higher height will increase the influence of the vibration. Compared with the method of installing by increasing the installation height of the eccentric wheel 14, the design of the eccentric groove is simpler and more convenient, and has higher stability.

[0066] Embodiment 3:

[0067] As Figure 2 shown, the difference from the above embodiment is that a transparent cover plate is hinged at the observation port.

[0068] The specific implementation process is as follows: The transparent cover plate protects the lidar while not affecting the lidar measurement; at the same time, it is also convenient for the operator to perform subsequent inspections and maintenance.

[0069] Embodiment 4:

[0070] As Figure 1 shown, the difference from the above embodiment is that both the vertical groove and the slider 3 are trapezoidal.

[0071] The specific implementation process is as follows: The trapezoidal vertical groove and slider 3 can effectively prevent the slider 3 from falling off the vertical groove.

[0072] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
