[0002] In civil engineering, water conservancy projects, and various infrastructure construction projects, the measurement of slope elevation is an essential and indispensable link. The accurate measurement of slope elevation plays a crucial role in the design, construction, and subsequent maintenance of the project. For example, in the construction of a dam, the elevation of the dam crest is directly related to the flood control capacity and stability of the dam. Therefore, it is particularly important to measure it accurately.

[0003] It is now found that a typical slope elevation measurement device in the prior art is, for example, the one with the publication number CN117760381B, a slope elevation measurement device for engineering surveying, including a housing.

The automatic measurement device includes a top plate and a moving wheel. The second motor drives the roller to rotate through the first rotating shaft and slowly rolls down the slope. When the moving wheel rolls down the slope, it will pull the measuring rope wound around the take-up coil.

The square rod 312 is square-connected to the rotating cylinder 313. When the knob 302 is rotated, the square rod 312 rotates accordingly, thereby driving the rotating cylinder 313 to rotate. The two limiting rings 314 play a role in limiting the sleeve 315. When the sleeve 315 moves left and right, it will drive the rotating cylinder 313 to move left and right.

[0051] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8As shown, a pushing and locking mechanism 316 is fixed to the bottom of the sleeve 315.

The first end of the second hydraulic channel 3163 is slidably connected to a third piston 3164. One end of the third piston 3164 is fixed to a pressing block 3165. The pressing block 3165 is connected to one side of the pushing block 3162 through a first compression spring 3166. The second end of the second hydraulic channel 3163 is slidably connected to a fourth piston 3167. A locking rod 3168 is fixed to the top of the fourth piston 3167. A first sliding channel 3169 is formed in the connecting rod 3161. The locking rod 3168 passes through the first sliding channel 3169. When manually pinching the pressing block 3165 and the pushing block 3162, the third piston 3164 moves. Hydraulic oil is stored in the second hydraulic channel 3163. The fourth piston 3167 moves upward under the action of the oil pressure, thereby driving the locking rod 3168 to move upward, facilitating the unlocking of the connecting rod 3161. Then, the pushing block 3162, the connecting rod 3161, and the sleeve 315 can be moved left or right as a whole, thereby driving the rotating cylinder 313 and the first gear 320 to move left or right as a whole, facilitating the meshing connection or separation of the first gear 320 and the second gear 321.

When the first gear 320 and the second gear 321 are meshed and connected together, the rotation of the first gear 320 drives the rotation of the second gear 321, thereby driving the rotation of the third gear 322, and then driving the rotation of the fourth gear 323. The rotating shaft 324 rotates accordingly, facilitating the fine adjustment of the angles of the first distance measuring instrument 6 and the second distance measuring instrument 8. When the first distance measuring instrument 6 and the second distance measuring instrument 8 are stored, the extrusion block 325 slides in the annular groove 326, and the extrusion block 325 extrudes the movable block 329, causing the overall movement of the movable block 329 and the fifth piston 328.

The sixth piston 403 penetrates the top of the second oil cylinder 401 and is connected to a moving frame 404. The two sides of the top of the moving frame 404 are symmetrically fixed with protective covers 406. The connecting pipe 330 serves to connect the first oil cylinder 327 and the second oil cylinder 401. The first oil cylinder 327 stores hydraulic oil. When the movable block 329 and the fifth piston 328 are extruded and move, the sixth piston 403 moves under the action of the oil pressure. When the lenses on the first distance measuring instrument 6 and the second distance measuring instrument 8 are completely facing downwards, the moving frame 404 and the two protective covers 406 are completely raised, and the two protective covers 406 respectively cover the two lenses, facilitating the protection function.

[0055] In this embodiment, as Figure 3 shown, a chute 405 is formed in the bottom of the bracket 2. The moving frame 404 is slidably connected in the chute 405. The chute 405 plays a role in limiting the up and down sliding of the moving frame 404.

[0057] As Figures 1 to 9Shown as follows: First, install the device at the required location. Pinch the push block 3162 and the pressing block 3165, the third piston 3164 moves, and the fourth piston 3167 and the locking rod 3168 move upward as a whole, thereby unlocking the connecting rod 3161. Then, manually push the push block 3162, the connecting rod 3161, and the sleeve 315 outward as a whole. The rotating cylinder 313 and the first gear 320 move, the first gear 320 leaves the second gear 321, release the pressing block 3165, and the pressing block 3165 automatically pops open. The third piston 3164, the fourth piston 3167, and the locking rod 3168 all return to their original positions, and the locking rod 3168 snaps into the corresponding groove 319, thereby relocking the connecting rod 3161. Then, manually turn the first distance measuring instrument 6 and the second distance measuring instrument 8 to roughly adjust the angles of the first distance measuring instrument 6 and the second distance measuring instrument 8. Then, unlock the connecting rod 3161, and then push the push block 3162, the connecting rod 3161, and the sleeve 315 inward. The rotating cylinder 313 and the first gear 320 move, and the first gear 320 meshes and connects with the second gear 321. After releasing the pressing block 3165 to lock the connecting rod 3161, manually rotate the knob 302 and the square rod 312. The rotating cylinder 313 and the first gear 320 rotate, the second gear 321 and the third gear 322 rotate, thereby driving the fourth gear 323 to rotate. The first distance measuring instrument 6 and the second distance measuring instrument 8 respectively rotate along with the corresponding rotating shafts 324, which is convenient for precisely adjusting the angles of the first distance measuring instrument 6 and the second distance measuring instrument 8. Align the laser emitted by the first distance measuring instrument 6 with the top of the building slope, and align the laser emitted by the second distance measuring instrument 8 with the bottom of the building slope. By observing the pointer 5 and the scale 10, the included angle between the two lasers can be calculated. Using the distance measured by the first distance measuring instrument 6, the distance measured by the second distance measuring instrument 8, and the included angle between the two lasers, the elevation of the building slope can be calculated. Finally, push the pressing rod 308, the pressing rod 308 squeezes the abutting block 311, and the abutting block 311 presses tightly against the first rubber ring 304, thereby locking the knob 302. The second rubber ring 310 presses tightly against the inner wall of the fixed channel 309, thereby locking the pressing rod 308.
