Description

Technical Field

[0001] The invention belongs to the technical field of ancient tree age measurement, and particularly relates to an improved ancient tree age measurement device. Background Art

[0002] Ancient trees refer to trees that are over 100 years old. They are not only important landscapes of scenic spots and historical sites, witnesses of long history, and symbols of social civilization, but also have value that cannot be ignored or underestimated in production and scientific research. As the aging of ancient trees becomes more serious, the aging trend continues to rise, and the losses are huge. Therefore, it is of great significance to accurately judge the age of ancient trees and slow down their aging in order to protect them.

[0003] One of the methods to measure the age of ancient trees is to measure the ratio of the age to the breast diameter of small trees of different ages around them, and create a curve. The approximate age of the old tree can then be calculated based on its breast diameter.

[0004] There are also some technical solutions for measuring the age of ancient trees in the prior art, such as a Chinese patent with application number CN202010985665.8, which discloses a method for predicting the age of ancient camphor trees, obtaining camphor tree growth index data, and measuring the camphor tree's breast diameter with a circumference ruler.

[0005] However, this method is not accurate enough after all, because the climate may change over hundreds of years, so the growth of trees may vary from year to year. A single breast diameter measurement has a large error. At the same time, for trees with larger diameters, manual measurement requires going around the tree, and the position of the tape measure may have a large deviation, making this method not only inefficient but also with large errors, and the accuracy of measuring the age of ancient trees needs to be improved.

[0029] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Example 1

[0031] like Figure 1-4 As shown, an improved ancient tree age measuring device comprises:

[0032] UAV body 1;

[0033] A mounting frame 2 provided on the drone body 1;

[0034] A driving wheel structure and a driven wheel structure are arranged on a side of the mounting frame 2 away from the drone body 1, and the driving wheel structure and the driven wheel structure are used to stick to the ancient tree and move on the surface of the ancient tree;

[0035] A number one wheel structure and a number two wheel structure are arranged on the mounting frame 2, wherein the number one wheel structure and the number two wheel structure respectively include a number one wheel 3 and a number two wheel 4 that fit together, and a transmission structure is arranged between the number one wheel structure and the driving wheel structure;

[0036] A connecting rod 5 is arranged on the mounting frame 2, and a spool 6 is arranged on the connecting rod 5. A tape measure 7 passing through the fitting portion between the number one wheel 3 and the number two wheel 4 is wound around the spool 6;

[0037] The drone body 1 drives the age measuring device to fly into the air and fly sideways, so that the driving wheel structure and the driven wheel structure are close to the trunk surface of the ancient tree, and the driving wheel structure drives the age measuring device to move in a circular direction along the trunk of the ancient tree. The driving wheel structure drives the No. 1 wheel structure and the No. 2 wheel structure to rotate through the transmission structure, so that the No. 1 wheel 3 and the No. 2 wheel 4 rotate, so that the tape measure 7 is pulled, and the distance moved by the driving wheel structure on the trunk is the distance the tape measure is pulled. The circumference of the trunk is measured by the tape measure 7, and the diameter value of the trunk is calculated by the circumference, and the age of the ancient tree is obtained by comparing it with the diameter values ​​of surrounding small trees of the same kind.

[0038] As a further solution of the present invention, the driving wheel structure and the driven wheel structure respectively include a driving shaft 8 and a driven shaft 9, a driving wheel 10 is concentrically arranged on the driving shaft 8, a driven wheel 11 is concentrically arranged on the driven shaft 9, and a driving motor 12 is provided at one end of the driving shaft 8.

[0039] As a further solution of the present invention, the number one wheel structure and the number two wheel structure further include a number two shaft 13 concentrically arranged with the number one wheel 3 and a number three shaft 14 concentrically arranged with the number two wheel 4 respectively.

[0040] As a further solution of the present invention, the transmission structure includes a first synchronous pulley arranged on the driving shaft 8 and a second synchronous pulley arranged on the second shaft 13, and a first synchronous belt 15 is arranged between the first synchronous pulley and the second synchronous pulley.

[0041] In the above embodiment, the drone body 1 drives the mounting frame 2 to lift off, and the lateral movement function of the drone body 1 makes the driving wheel 10 and the driven wheel 11 on the mounting frame 2 close to the tree trunk. The driving motor 12 connected to the driving wheel 10 drives the driving shaft 8 to rotate, so that the driving wheel 10 rotates, and the driving wheel 10 can drive the mounting frame 2 and the drone body 1 to move along the surface of the tree trunk. When the driving shaft 8 rotates, it drives the No. 1 synchronous belt 15 to rotate, so that the No. 2 shaft 13 rotates. The No. 2 shaft 13 drives the No. 1 wheel 3 to rotate, so that the No. 2 wheel 4 also rotates. When the No. 1 wheel 3 and the No. 2 wheel 4 rotate, the soft tape measure 7 is pulled and the spool 6 rotates. The No. 1 wheel 3 has the same diameter as the driving wheel 10, so that the distance the tape measure 7 moves is the distance the driving wheel 10 moves on the tree trunk. When the drone body 1 flies a circle along the tree trunk, the circumference of the trunk can be obtained by the movement distance of the tape measure 7, and the average diameter of the trunk can be obtained by the circumference. By taking multiple measurements of ancient trees at different heights and comparing them with young trees multiple times, and calculating the ratio of diameter values ​​at the same height, more accurate tree age data can be obtained.

[0042] Among them, auxiliary wheels are arranged on the mounting frame 2, which can make the mounting plate 2 more stable, thereby ensuring that the age measuring device can smoothly move circumferentially along the tree trunk. The device works best for trees with larger diameters and relatively flat surfaces. For trees with larger cracks and larger scars, larger errors will be generated during the movement of the active wheel.

[0043] As a further solution of the present invention, a No. 1 shaft 16 is provided on the mounting frame 2, and a worm 17 is provided at one end of the No. 1 shaft 16 close to the drone body 1, and the driving shaft 8 is connected to the worm 17 through a No. 2 synchronous belt. A connecting block 18 is provided between the drone body 1 and the mounting frame 2, and the connecting block 18 is rotatably connected to the mounting frame 2. A No. 4 shaft is provided on the connecting block 18, and a fan-shaped worm gear 19 meshing with the worm 17 is concentrically arranged on the No. 4 shaft.

[0044] As a further solution of the present invention, a coil spring is provided between the connecting block 18 and the mounting frame 2 .

[0045] In the above embodiment, the driving shaft 8 drives the first shaft 16 to rotate through the second synchronous belt, so that the worm 17 rotates, and the worm 17 drives the worm wheel to rotate so that the connecting block 18 rotates, thereby causing the drone body 1 to deflect. After the drone body 1 deflects, it produces oblique flight, so that the drone body 1 produces a lateral squeezing force on the mounting frame 2. Under the dual blessing of the oblique flight power of the drone body 1 itself, the driving wheel 10 and the driven wheel 11 can be close to the tree trunk, thereby preventing the driving wheel 10 from rotating and slipping, and preventing one side of the driving wheel 10 from moving downward.

[0046] When the connecting block 18 rotates relative to the mounting frame 2 , the coil spring is tightened. After the age measuring device completes the measurement, the coil spring drives the connecting block 18 to rotate to the initial position, so that the drone body 1 can fly vertically relative to the mounting frame 2 .

[0047] The sector angle of the sector worm gear 19 is preferably 60°, and the rotation angle of the drone body 1 is preferably controlled at 20°.

[0048] As a further solution of the present invention, a cavity 20 is provided inside the driving wheel 10 and the driven wheel 11, and a plurality of through holes connecting the outside and the cavity 20 are provided on the driving wheel 10 and the driven wheel 11 along their respective circumferential directions, and a plug plate 21 is provided at the through hole. A filling cavity 22 is provided on the mounting frame 2, and a moving block 23 is provided at the filling cavity 22. A reset spring 24 for driving the moving block 23 to move is provided between the moving block 23 and the mounting frame 2. A guide rail 25 is provided on the mounting frame 2, and a clamping block 26 is provided in the guide rail 25. A connecting rope 27 is provided between the clamping block 26 and the moving block 23. A channel 28 is provided between the filling cavity 22 and the cavities 20 of the driving wheel 10 and the driven wheel 11, and a liquid is provided in the channel 28.

[0049] As a further solution of the present invention, one end of the guide rail 25 located in the filling cavity 22 is a closed end.

[0050] In the above embodiment, when the driving wheel 10 and the driven wheel 11 are tightly pressed against the tree trunk, the corresponding plug plate 21 is squeezed into the cavity 20, so that the liquid in the channel 28 is pressed toward the filling cavity 22, thereby increasing the pressure on the moving block 23. The moving block 23 moves under the action of the pressure, so that the connecting rope 27 is pulled, so that the clamping block 26 is pulled in the direction of the moving block 23. After the clamping block 26 moves, it is separated from the surface of the number one wheel 3, so that the number one wheel 3 can rotate freely. That is, when the driving wheel 10 is idling or the outer ring of the driving wheel 10 is separated from the tree trunk, the clamping block 26 contacts the surface of the number one wheel 3, so that the number one wheel 3 cannot rotate, and at this time the tape measure 7 does not move, thereby reducing the occurrence of measurement errors.

[0051] Among them, one end of the guide rail 25 is closed so that the liquid does not act on the block 26, so that the movement resistance of the block 26 is reduced, so that the block 26 can move normally.

[0052] Among them, when the plug plate 21 contacts the surface of the trunk, the friction between the driving wheel 10 and the driven wheel 11 and the trunk is increased, so that the probability of the driving wheel 10 idling is reduced. At the same time, the plug plate 21 can prevent the driving wheel 10 and the driven wheel 11 from sliding in the vertical direction, thereby preventing the age measuring device from tipping over on one side.

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
