Description

Technical Field

[0001] The utility model relates to the technical field of landform measurement, in particular to a landform measurement instrument capable of dealing with complex landforms. Background Art

[0002] Topography is the general term for various forms on the earth's surface. The surface forms are diverse and their causes are also different. They are the result of the combined effects of internal and external geological forces on the earth's crust. Topography and geomorphology measurement refers to the work of surveying and mapping topographic maps, that is, measuring the projection position and elevation of the objects and terrain on the earth's surface on the horizontal plane. At present, topography and geomorphology measurement is usually carried out using geomorphometers. Geomorphometers are widely used in precision engineering measurement or deformation monitoring fields such as large-scale buildings on the ground and underground tunnel construction. When geomorphometers are used for topographic measurement in the field, they need to be supported by brackets. A Chinese patent discloses a topography and geomorphology measurement device under complex conditions. The authorization announcement number is: CN213874285U. The patent can arbitrarily extend or shorten the contact between the support legs and the ground, and can play a good supporting effect even on uneven ground surfaces.

[0003] When current topographic surveying instruments are used for outdoor measurement, the uneven outdoor terrain structure makes it impossible for the topographic surveying instruments to maintain effective support. Although the existing technology can adjust the support, it is still impossible to provide effective and stable support when dealing with complex terrain, especially when the slope is large. In addition, the existing support structure for topographic surveying instruments cannot be effectively stored after use, so that after the topographic surveying instrument is used, the support structure at the bottom will occupy a large space, which makes the carrying process very troublesome.

[0035] The working principle and usage process of the present utility model: Before using the geomorphic surveying instrument, the position of the multi-section support rod 5 is rotationally adjusted and limited through the connecting swivel 3, the rotating seat 4, the multi-section support rod 5 and the limit knob 6. By using the multi-section telescopic structure design of the multi-section support rod 5, it is convenient for the geomorphic surveying instrument to cope with the support work of complex landforms during support. After the telescopic lengths of the multiple multi-section support rods 5 are adjusted, the bottom of the multi-section support rod 5 is supported by cooperating with the rotating support 7 and the anchoring rod 8, further ensuring the support stability of the geomorphic surveying instrument during support measurement.

[0036] Then, the main body 2 of the measuring instrument is connected to the support assembly. During connection, in an elastic limiting manner, the limit springs 21 drive the two connecting rods 23 and the limit clamping plates 24 to limit and clamp the main body 2 of the measuring instrument, so as to ensure that the main body 2 of the measuring instrument can be stably supported during use and ensure its stability during measurement.

[0037] When in use for measurement, it is necessary to adjust the measurement angle of the main body 2 of the measuring instrument. During the specific adjustment process, by setting a connecting plate 11, a universal ball head seat 12, a clearance groove 13, a threaded sleeve 14, a locking bolt 15, a movable ball head 16 and a movable rod 17 between the support base 1 and the main body 2 of the measuring instrument, it is convenient to adjust the position of the movable rod 17 through the movement of the movable ball head 16 in the universal ball head seat 12. The threaded sleeve 14 and the locking bolt 15 are convenient for limiting the position of the movable ball head 16, so as to facilitate flexible adjustment according to needs during measurement. Moreover, this adjustment method can adjust the position of the geomorphological measuring instrument at any angle, so as to ensure that the geomorphological measuring instrument can better measure the terrain and landform, improving the convenience of use during the measurement process of the geomorphological measuring instrument;

[0038] Finally, after the measurement is completed, the main body 2 of the measuring instrument is disassembled from the inside of the U-shaped limit plate 18, so that the main body 2 of the measuring instrument can be stored separately after disassembly. At the same time, by using the limit card plate 9 and the limit side plate 10 on the side of the support base 1, the multi-section support rod 5 in the storage state can be restricted in position after the measurement is completed, so as to facilitate storage, making the support structure not occupy space after being used for support and being convenient to carry better, making the use more convenient.
