DETAILED DESCRIPTION

[0031] like Figures 1-6 As shown, a portable surveying and mapping device for forest resource survey includes a storage box 1, a surveying and mapping instrument 2 and a bracket.

[0032] The interior of the storage box 1 is provided with a surveying instrument storage cavity 3 and a bracket storage cavity 4 in sequence from top to bottom.

[0033] The upper part of the surveying instrument storage chamber 3 is an open structure. A lifting platform 5 is installed inside the surveying instrument storage chamber 3 for sliding in the vertical direction and a lifting drive mechanism is provided for driving the lifting platform 5 to move linearly. The surveying instrument 2 is fixedly arranged on the upper part of the lifting platform 5.

[0034] In this embodiment, the lifting drive mechanism includes a transmission shaft 6 that is horizontally rotatably mounted at the bottom of the surveying instrument storage chamber 3 and two first lead screws 7 that are symmetrically rotatably mounted on both sides of the interior of the surveying instrument storage chamber 3. One end of the transmission shaft 6 extends to the outside of the storage box 1 and is fixedly mounted with a first handwheel 8 for driving its rotation. The transmission shaft 6 is respectively fitted with active bevel gears 9 at locations near the two first lead screws 7. The upper ends of the two first lead screws 7 are respectively rotatably connected to first mounting seats 10 fixedly mounted on the inner side panels of the storage box 1, and the lower ends of the two first lead screws 7 are respectively fixedly mounted with driven bevel gears 11 that mesh with the corresponding active bevel gears 9. The middle portions of the two first lead screws 7 pass through the lifting platform 5, and two first screw sleeves 12 that are respectively threadedly connected to the two first lead screws 7 are symmetrically fixedly mounted on the lifting platform 5.

[0035] The operator rotates the transmission shaft 6 by turning the first hand wheel 8. During the rotation of the transmission shaft 6, the two first lead screws 7 rotate synchronously through the meshing transmission action of the two sets of active bevel gears 9 and the driven bevel gears 11. During the rotation of the two first lead screws 7, the two first screw sleeves 12 drive the lifting platform 5 and the surveying instrument 2 to perform linear motion.

[0036] One side of the bracket storage cavity 3 is an open structure, and the storage box 1 is symmetrically fixed with two first connecting plates 13 at the upper and lower ends of the opening side of the bracket storage cavity 4, and two second connecting plates 14 are symmetrically fixed at the bottom of the storage box 1.

[0037] The bracket includes a mounting plate 15, with a support assembly mounted on one side and a connecting assembly mounted on the other. When not performing surveying, the connecting assembly is fixedly connected to the two first connecting plates 13, so that the mounting plate 15 is fixedly connected to the outside of the bracket storage cavity 4 and the support assembly is stored within the cavity. When performing surveying, the connecting assembly is fixedly connected to the two second connecting plates 14, so that the mounting plate 15 is fixedly connected to the bottom of the storage box 1 and the supporting assembly is fixedly supported on the ground.

[0038] In this embodiment, the support assembly includes a sleeve 16 fixedly mounted on one side of the mounting plate 15. A second mounting seat 17 is fixedly mounted in the middle of the sleeve 16. A second lead screw 18 is rotatably mounted in the sleeve 16 between the mounting plate 15 and the second mounting seat 17. A drive shaft 19 is rotatably mounted on the outside of the sleeve 16 on the mounting plate 15 for driving the second lead screw 18. Specifically, one end of the drive shaft 19 is rotatably connected to a portion of the mounting plate 15 near the outside of the sleeve 16, and the other end is fixedly mounted with a second handwheel 20 for driving its rotation. A driving spur gear 21 is mounted in the middle of the drive shaft 19, one end of which extends into the interior of the sleeve 16. A driven spur gear 22 is mounted on the end of the second lead screw 18 near the mounting plate 15, which meshes with the driving spur gear 21. When the driving shaft 19 is rotated by the second hand wheel 20 , the second lead screw 18 is rotated by the meshing transmission action of the driving spur gear 21 and the driven spur gear 22 .

[0039] A second threaded sleeve 23 is threadedly mounted on the middle portion of the second lead screw 18. Multiple first lugs 24 are uniformly fixed along the circumference of the outer wall of the second threaded sleeve 23. Each first lug 24 slidably engages with a limiting slot 25 provided on the circumferential wall of the sleeve 16. One end of each first lug 24, located outside the sleeve 16, is hingedly connected to one end of a support leg 25. A second lug 26 is fixedly mounted on the middle portion of each support leg 25, facing the sleeve 16. Multiple third lugs 27 are uniformly disposed on the outer circumference of the end of the sleeve 16 facing away from the mounting plate 15, corresponding to each second lug 26. A supporting link 28 is hingedly mounted between each corresponding second lug 26 and third lug 27. When the second lead screw 18 rotates, the second threaded sleeve 23 drives the multiple first lugs 24 to move linearly in sync, thereby causing the multiple support legs 25 to expand or retract.

[0040] A support seat 29 is installed at one end of each support leg 25 away from the first ear plate 24. Specifically, one end of the support seat 29 is symmetrically fixed with two mounting bosses 30 on both sides of the support leg 26, and each mounting boss 30 is fixed with a connecting sleeve 31. The two connecting sleeves 31 are respectively rotatably engaged with two connecting shafts 32 fixedly provided on the sides of the support leg 25, and one of the connecting sleeves 31 is installed with a top screw 33 for fixing it.

[0041] A mounting bracket 34 with an L-shaped cross-section is fixedly mounted on the other end of each support base 29. One end of the mounting bracket 34 is fixedly connected to the support base 29 by welding. The other end of the mounting bracket 34 has a through-hole, and two mounting nuts 35 are fixedly mounted on either side of the through-hole by welding. The two mounting nuts 35 are commonly mounted on a threaded anchor screw 36. Two handles 37 are symmetrically fixed to one end of each anchor screw 36. The middle portion of each anchor screw 36 extends through an avoidance hole 38 provided in the support base 29, and the other end has a pointed cone-shaped structure.

[0042] In this embodiment, the angle of the support seat 29 relative to the support leg 25 can be adjusted so that the anchor screw is perpendicular to the ground to which it corresponds. In addition, the anchor screw 36 can be rotated by turning the handle at the end of the anchor screw 36 to adjust the distance it passes through the support seat 29. Through the above settings, the support assembly can be firmly supported on uneven ground.

[0043] In this embodiment, the connection assembly includes three evenly spaced connection bosses 39 fixedly disposed on the other side of the mounting plate 15. A guide rod 40 is fixedly disposed between each two adjacent connection bosses 39. A slide 41 is slidably mounted on each of the two guide rods 40. A spring 42 is sleeved on each guide rod 40. One end of each spring 42 is fixedly connected to a corresponding slide 41, and the other end is fixedly connected to the connection boss 39 located in the middle. A plug-in board 43 is fixedly disposed on the side of each slide 41 facing the outer end of the mounting plate 15. The two first connection plates 13 are each provided with a first slot 44 adapted to fit the plug-in board 43 at one end away from the storage box 1, and the two second connection plates 14 are each provided with a second slot 45 adapted to fit the plug-in board 43 at one end closer to the storage box 1.

[0044] In addition, the spacing and cross-sectional profiles of the two first connecting plates 13 and the two second connecting plates 14 are the same, and two third slots 46 adapted to the two first connecting plates 13 and the two second connecting plates 14 are symmetrically opened at both ends of the mounting plate 15 .

[0045] Two handle straps 47 are symmetrically fixedly provided on both sides of the exterior of the storage box 1 , and a worker can carry the entire storage box 1 for movement by holding the drawstrings.

[0046] A cover plate 48 that matches the contour of the upper opening end of the surveying instrument storage cavity 3 is fixedly provided on the upper part of the surveying instrument 2. The cover plate 48 can block the upper opening of the surveying instrument storage cavity 3 to prevent a large amount of external rainwater and debris from entering the interior of the surveying instrument storage cavity 3, thereby avoiding damage to the surveying instrument 2.

[0047] like Figure 1-Figure 2 As shown, when not surveying, the surveying instrument is stored within the surveying instrument storage cavity, while the bracket's mounting plate rests flush against the outer opening of the bracket storage cavity. The support legs of the support assembly are gathered and stored within the bracket storage cavity. The two first connecting plates on the storage box engage with the two third connectors on the mounting plate, while the two plug-in plates of the connection assembly engage with the two first slots on the first connecting plate, thereby securing the connection between the bracket's connecting plates and the storage box. The surveying device is integrated into a single storage box for unified portability, reducing overall size and facilitating travel through forested areas.

[0048] like Figure 3-Figure 4 As shown, when surveying and mapping operations are required, the staff can slide the two plug-in plates out of the two first slots by relatively moving the two slides. After removing the mounting plate and the support assembly from the bracket storage cavity, the multiple support legs can be spread outward by turning the second hand wheel, and then the entire bracket is placed on the bottom of the storage box. The staff again relatively moves the two slides so that the support assembly is located between the two second connecting plates, and the two second connecting plates are plugged into and matched with the third slots on the mounting plate. After releasing the force on the slides, the two slides are moved away from each other under the action of the spring, so that the two plug-in plates are plugged into and matched with the second slots on the two second connecting plates, thereby fixing the entire bracket to the bottom of the storage box, and then fixing the support assembly to the ground through multiple anchor screws. Finally, the staff rotates the first hand wheel to make the lifting platform drive the surveying instrument to move vertically upward and move it to the top of the storage box, and then surveying and mapping operations can be carried out.

[0049] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
