DETAILED DESCRIPTION

[0016] Reference Figure 1-Figure 5 , a surveying device for land assessment in natural resource engineering, comprising: A fixed housing 1 is provided, wherein a fixed shaft 3 is fixedly connected to the inner wall of the fixed housing 1, a fixed roller 11 is fixedly mounted on the fixed shaft 3, a measuring ruler 12 is fixedly wound around the fixed roller 11, and a fixed opening 10 corresponding to the measuring ruler 12 is opened on the inner wall of the fixed housing 1; The cleaning structure 8 includes a movable plate 87 slidably connected to the inner wall of the fixed opening 10, a connecting shaft 81 is rotatably connected between the movable plates 87, a cleaning roller 82 is fixedly sleeved on the connecting shaft 81, a one-way shaft 83 is fixedly sleeved on the connecting shaft 81, a fixed gear 84 is rotatably sleeved on the one-way shaft 83, a fixed block 86 is fixedly connected to the inner wall of the fixed opening 10, a fixed rack 85 meshing with the corresponding fixed gear 84 is fixedly mounted on the fixed block 86, and a transmission structure is installed in the fixed housing 1; Under the action of the transmission structure, the movable plate 87 moves back and forth, driving the connecting shaft 81 and the cleaning roller 82 to move back and forth, thereby cleaning the surface of the measuring ruler 12. At the same time, the fixed gear 84 moves along with the connecting shaft 81. Under the action of the fixed rack 85, the fixed gear 84 rotates back and forth, cooperating with the one-way shaft 83 to make the connecting shaft 81 rotate in one direction, thereby improving the cleaning effect of the cleaning roller 82. The transmission structure includes a fixed rod 88 fixedly connected to the side wall of the movable plate 87, the side wall of the fixed rod 88 is fixedly connected to the extrusion plate 89, the side wall of the extrusion plate 89 is fixedly connected to the connecting block 813, a connecting spring 814 is fixedly connected between the connecting block 813 and the inner wall of the fixed housing 1, the inner wall of the fixed housing 1 is rotatably connected to the mounting shaft 810, a connecting cam 811 corresponding to the extrusion plate 89 is fixedly sleeved on the mounting shaft 810, the mounting shaft 810 and the fixed shaft 3 are connected by a belt transmission assembly 812, one end of the fixed shaft 3 passes through the inner wall of the fixed housing 1 and extends to the outside of the fixed housing 1, and the end of the fixed shaft 3 located outside the fixed housing 1 is fixedly connected to the rotating handle 2; Rotating the rotating handle 2 rotates the fixed shaft 3. Under the action of the belt transmission assembly 812, the installation shaft 810 rotates accordingly, causing the connecting cam 811 fixedly connected to the installation shaft 810 to rotate together. During the rotation process, the connecting cam 811 squeezes the squeezing plate 89, causing the squeezing plate 89 to move, driving the connecting block 813 to move together, causing the connecting spring 814 to deform. As the connecting cam 811 continues to rotate, the elastic force of the connecting spring 814 pushes the connecting block 813 back to its original position, thereby causing the squeezing plate 89 to move back and forth, driving the fixed rod 88 and the movable plate 87 to move back and forth together. The outer sides of the extrusion plate 89 and the connecting cam 811 are fixedly wrapped with a protective layer, and the side wall of the extrusion plate 89 is rounded to facilitate the mutual extrusion between the extrusion plate 89 and the connecting cam 811; A fixed structure 9 is installed inside the fixed housing 1. The fixed structure 9 includes a connecting plate 92 that is slidably connected to the inner wall of the fixed housing 1. The bottom end of the connecting plate 92 is fixedly connected to a plurality of connecting rods 93. The top end of the cleaning roller 82 is fixedly connected to a threaded rod 94. The outer side of the threaded rod 94 is rotatably sleeved with a threaded sleeve 95. The thread of the threaded rod 94 is fine and dense. At the same time, the transmission ratio of the connecting worm 91 and the fixed worm gear 97 is small. Therefore, when the measuring scale reaches the maximum value, the threaded rod 94 will not be separated from the threaded sleeve 95. The top end of the threaded sleeve 95 is rotatably connected to a mounting block 96, and the mounting block 96 is fixedly connected to the inner wall of the fixed housing 1. The fixed shaft 3 is fixedly sleeved with a connecting worm 91, and the threaded sleeve 95 is fixedly sleeved with a fixed worm gear 97 that meshes with the connecting worm 91. When the fixed shaft 3 rotates, the connecting worm 91 fixedly sleeved on the fixed shaft 3 rotates accordingly, driving the fixed worm wheel 97 meshing with the connecting worm 91 to rotate accordingly, driving the threaded sleeve 95 fixedly connected to the fixed worm wheel 97 to rotate together, so that the threaded rod 94 threadedly connected to the threaded sleeve 95 moves downward, driving the connecting plate 92 and the connecting rod 93 to move together, so that the connecting rod 93 is inserted into the ground, thereby achieving the effect of fixing the fixed housing 1 when the measuring ruler 12 is pulled for measurement; The lower inner wall of the fixed housing 1 is provided with a through hole matching each connecting rod 93, and the side wall of each connecting rod 93 is chamfered to facilitate the insertion of the connecting rod 93 into the ground; The side wall of the measuring ruler 12 is slidably mounted with a fixing plate 4, and a fixing groove 5 is opened on the side wall of the fixing plate 4. The inner wall of each fixing groove 5 is slidably connected with a foot pedal 6, and the foot pedal 6 extends to the outside of the fixing plate 4. The bottom end of each foot pedal 6 is fixedly connected to a fixing plug rod 7, and the side wall of the fixing plate 4 is fixedly connected with a fixing card block. The side wall of the fixed shell 1 is opened with a fixing card slot corresponding to the fixing card block, so that the fixing plate 4 can be fixed; the fixing plate 4 covers the fixing opening 10, and the side wall of the fixing plate 4 is fixedly mounted with a flexible protective pad. The bottom end of the fixing plate 4 is flush with the side wall of the fixed shell 1, and the fixing plate 4 blocks the fixing opening 10 to prevent debris from entering the fixed shell 1 when the device is not in use; Remove the fixing plate 4 from the fixing housing 1, place the fixing plate 4 on the ground, step on the foot pedal 6, insert the fixing rod 7 at the bottom end of the foot pedal 6 into the ground, and fix the fixing plate 4 and one end of the measuring ruler 12 to facilitate measurement; The side wall of the fixed shell 1 is fixedly connected with a fixed handle to facilitate carrying the device. A placement pad is fixedly installed on the fixed shell 1, and a fixed cover is rotatably installed on the fixed shell 1. The fixed cover can be opened to repair the internal structure of the fixed shell 1.

[0017] When the measuring scale 12 is pulled to the other end of the measuring point, the fixing plate 4 is placed on the ground, the foot pedal 6 is stepped on, and the fixed plug rod 7 at the bottom end of the foot pedal 6 is inserted into the ground to fix the fixing plate 4 and one end of the measuring scale 12 for easy measurement. After the measurement is completed, the fixed plate 4 is separated from the ground, and the rotating handle 2 is rotated to rotate the fixed shaft 3. Under the action of the belt transmission assembly 812, the installation shaft 810 rotates accordingly, and the connecting cam 811 fixedly connected to the installation shaft 810 rotates together. During the rotation process, the connecting cam 811 squeezes the squeezing plate 89, causing the squeezing plate 89 to move, driving the connecting block 813 to move together, causing the connecting spring 814 to deform. As the connecting cam 811 continues to rotate, the elastic force of the connecting spring 814 pushes the connecting block 813 back to its original position, thereby causing the squeezing plate 89 to move back and forth, driving the fixed rod 88 and the movable plate 87 to move back and forth together. The back and forth movement of the movable plate 87 will drive the connecting shaft 81 and the cleaning roller 82 to move back and forth accordingly, cleaning the surface of the measuring ruler 12. At the same time, the fixed gear 84 will move together with the connecting shaft 81. Under the action of the fixed rack 85, the fixed gear 84 rotates back and forth, cooperating with the one-way shaft 83 to make the connecting shaft 81 rotate unidirectionally, so as to improve the cleaning effect of the cleaning roller 82.
