Description

Technical Field

[0001] The invention relates to the technical field of topographic measurement, in particular to a land planning topographic flatness measurement device. Background Art

[0002] Land planning refers to the process of rationally allocating and managing land resources according to specific economic, social, environmental and other development goals. It involves the type of land use, layout, facility construction, ecological protection and other aspects to achieve sustainable development and optimal use of resources. Land planning usually includes different levels and types such as urban planning, rural planning, and regional planning. Terrain flatness refers to the height difference and flatness of the land surface within a certain range, reflecting the degree of undulation of the surface, and is often used to evaluate the suitability of a plot of land, such as the feasibility of using it for construction, agriculture or other purposes.

[0003] The existing Chinese patent publication number is CN116147468B, and its name is a terrain flatness measuring device for urban planning, which includes a frame, fixed rails are installed on the left and right sides of the top of the frame near the rear, and indicating components are installed on the top of the fixed rails. Fixed tubes located below the fixed rails are embedded and installed on the left and right sides of the top of the frame. The movement of the colored liquid is realized by converting the up and down displacement into the relative distance or relative proximity of the guide block, and the relative proximity or relative distance of the guide block is converted into pressure. The flatness of the ground is directly obtained by inputting the colored liquid into the first temporary storage tank and the second temporary storage tank in combination with the scale on the outer side. The whole process is relatively visual, and there is no need for complicated operations. You only need to push the device to the point to be measured to measure the ground undulations. There is no need to stop moving and then measure, and the function of dynamically measuring the ground flatness during movement is realized.

[0004] In the prior art, a hand-pushed device is moved to draw an image, thereby realizing the measurement of the terrain flatness of the current obstacle-crossing wheel passing position. This method is only applicable to a smaller measurement area. When the measurement area is larger, it is necessary to measure back and forth multiple times. The operation is cumbersome and inefficient, and it is impossible to measure every position. The measurement result is not accurate enough.

During the movement, the cleaning motor drives the cleaning roller 32 to operate to clean the ground in front of the device and remove fallen leaves and gravel. During the cleaning process, the upper baffle plate 34, the lower baffle plate 35 and the baffle rod 36 are set to block the fallen leaves and gravel rolled up by the cleaning roller 32, and the cleaning roller 32 is brushed. The hair is combed, and the support frame 2, inner tube 3, stabilizing platform 4 and counterweight 5 cooperate to ensure that the ultrasonic detector 10 is always stably maintained in the direction of gravity to avoid affecting the measurement results. After the measurement, the drive motor 16 operates in the reverse direction, and the first gear 17 is first meshed and connected with the second gear 18, so that the connecting seat 13 rotates and resets, the first gear 17 is separated from the second gear 18, and the third gear 27 is meshed and connected with the fourth gear 28, pulling the connecting plate 9 so that the two connecting plates 9 are moved to one side relatively close to each other and retracted to avoid damage caused by accidental touch when not in use.
