Detailed implementation manners

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Embodiment 1: Refer to Figures 1 - 6 , a portable measuring device for forestry survey and planning, comprising: a back frame 1, and further comprising: a strap 102 symmetrically and fixedly connected to the back frame 1; a placement box 2 fixedly arranged on the back frame 1; a measuring instrument 409 arranged in the placement box 2; a first partition 201 fixedly arranged in the placement box 2; a lifting assembly arranged between the first partition 201 and the measuring instrument 409; a second partition 203 fixedly arranged between the first partition 201 and the placement box 2; a first cavity 204 arranged between the second partition 203 and the placement box 2; a multi-stage telescopic rod 205 arranged in the first cavity 204, and one end of the multi-stage telescopic rod 205 penetrates through the placement box 2; an auxiliary support assembly arranged on the back frame 1; a controller 406 fixedly arranged on the first partition 201.

[0030] A third cavity 4 is arranged on the upper side of the first partition 201, a placement plate 404 is fixedly connected to the lower side of the measuring instrument 409, the lifting assembly comprises a plurality of electric telescopic rods 401 arranged between the placement plate 404 and the first partition 201, and a top cover 411 is arranged on the upper side of the placement box 2.

[0031] When the staff needs to carry the measuring device up the mountain to conduct forestry survey and planning, they carry the back frame 1 on their backs through the shoulder strap 102, and fix the placement box 2 on the back frame 1, which is convenient for carrying equipment such as the measuring instrument 409. When the staff feels tired on the mountain, they start the multi-stage telescopic rod 205 set in the first cavity 204. One end of the multi-stage telescopic rod 205 passes through the placement box 2 and extends out to support the placement box 2, so that the entire device is in a stable state. The staff can lean on the device to take a short rest, reducing the pressure of the shoulder strap 102 on the staff's shoulders.

[0032] In the past, when workers felt tired while carrying the measuring instrument 409 up the mountain, they had to remove the measuring instrument 409 to rest, which was cumbersome and might affect work progress. The present device extends the support placement box 2 through the multi-stage telescopic rod 205, allowing workers to take a short rest, thereby improving work convenience and efficiency.

[0033] When taking measurements, first open the top cover 411 of the placement box 2, start the electric telescopic rod 401 set between the placement plate 404 and the first partition 201, and the electric telescopic rod 401 extends to lift the placement plate 404 together with the measuring instrument 409 upward and raise them out of the placement box 2, making it convenient for staff to operate the measuring instrument 409 for measurement. The placement box 2 protects the measuring instrument 409, effectively preventing damage to the measuring instrument 409 when it is carried.

[0034] Example 2: Reference Figures 1 - 6 A portable measuring device for forestry survey and planning is basically the same as Example 1, and further, a fixing ring 207 is symmetrically fixedly connected in the first cavity 204, a limiting ring 206 is fixedly connected to the multi-stage telescopic rod 205, and the limiting ring 206 is arranged between the two fixing rings 207, a sleeve 209 is fixedly connected in the first cavity 204, and a pressure sensor 210 is arranged in the sleeve 209.

[0035] A tension spring 208 is fixedly connected between the multi-stage telescopic rod 205 and the placement box 2 .

[0036] When the multi-stage telescopic rod 205 in the first cavity 204 is started, the limiting ring 206 on the multi-stage telescopic rod 205 moves between the two fixed rings 207 to play a limiting and guiding role. One end of the multi-stage telescopic rod 205 passes through the placement box 2 and extends out to support the placement box 2. During this process, the tension spring 208 connects the multi-stage telescopic rod 205 and the placement box 2 to play a buffering and auxiliary reset role. The pressure sensor 210 in the sleeve 209 can monitor the supporting pressure of the multi-stage telescopic rod 205 to ensure stable support and prevent the multi-stage telescopic rod 205 from over-supporting the placement box 2. When the measuring instrument 409 is transported, when the pressure detected by the pressure sensor 210 reaches a specified value, the controller 406 controls the multi-stage telescopic rod 205 to stop extending.

[0037] Both the output end and the bottom end of the electric telescopic rod 401 are fixedly connected with limit balls 403. Ball sleeves 402 for the limit balls 403 are fixedly connected to both the placement plate 404 and the first partition plate 201. The limit balls 403 are rotatably arranged in the ball sleeves 402. A spirit level 405 is fixedly connected to the lower side of the placement plate 404.

[0038] A connecting plate 410 is fixedly connected to the upper side of the measuring instrument 409. The connecting plate 410 and the top cover 411 are fixedly connected by bolts 412.

[0039] Start the electric telescopic rod 401. The limit balls 403 at its output end and bottom end rotate in the ball sleeves 402 on the placement plate 404 and the first partition plate 201, ensuring the stable telescoping of the electric telescopic rod 401. Then, the placement plate 404 together with the measuring instrument 409 is lifted upward and rises from the placement box 2. The spirit level 405 on the lower side of the placement plate 404 can monitor the horizontal state of the placement plate 404 in real time to ensure that the measuring instrument 409 is in a horizontal working state. When the spirit level 405 detects its tilt data, the corresponding electric telescopic rod 401 is controlled by the controller 406 to extend to adjust the measuring instrument 409, so that it is always in a horizontal state, effectively improving its measurement accuracy and being applicable to areas such as mountains.

[0040] Example 3: Refer to Figures 1 - 6 , a portable measuring device for forestry investigation and planning, which is basically the same as Example 1. Further, a groove 101 matching the measuring instrument 409 is provided on the back frame 1.

[0041] When the measuring instrument 409 extends out, it is observed through the groove 101, and the top cover 411 can be used to block light, preventing direct sunlight from entering the measuring instrument 409 and affecting the accuracy of its detection.

[0042] On the side of the second partition plate 203 away from the first cavity 204, there is a second cavity 3. A cooling fan 301 is arranged in the second cavity 3. An air intake hole 302 matching the cooling fan 301 is provided at the bottom of the placement box 2. An exhaust hole 413 is provided on one side of the placement box 2.

A plurality of connection holes 407 are provided on the placement plate 404, and a cooling cavity 408 is provided between the placement plate 404 and the measuring instrument 409.

[0043] During the operation of the device, the cooling fan 301 plays a role. The air intake hole 302 sucks in outside cold air, which cools the measuring instrument 409 through the cooling cavity 408, and then the hot air is discharged from the exhaust hole 413. The buffer pad 414 on the placement plate 404 can prevent the measuring instrument 409 from being damaged due to excessive oscillation.

[0044] A buffer pad 414 is fixedly connected to the placement plate 404.

[0045] Embodiment 4: Refer to Figures 1 - 6 , a portable measuring device for forestry investigation and planning, is basically the same as Embodiment 1. Further, the auxiliary support assembly includes self-locking support rods 5 symmetrically and rotatably connected to the back frame 1. A limit block 501 matching the self-locking support rods 5 is fixedly connected to one side of the back frame 1, and a buckle 502 matching the self-locking support rods 5 is fixedly connected to the upper side of the back frame 1.

[0046] The self-locking support rods 5 provide additional support points for the device. During measurement, triangular support can be provided to improve the stability of the measuring instrument 409 during operation and prevent the measuring instrument 409 from shaking and affecting its measurement results.
