Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy benchmarks, in particular to a benchmark structure for water conservancy engineering surveying and mapping. Background Art

[0002] At present, water level benchmarks are used in some important flood prevention locations such as rivers, lakes, reservoirs, hydropower stations, and irrigation areas. Water level benchmarks can detect the extent of water level rise and thus determine whether the water level is rising or falling, which serves as an important indicator for people's flood prevention judgment.

[0003] Most of the benchmarks used in water conservancy projects are cement columns fixed on the bottom of the water with scales on the outer surface. This type of benchmark is large in size, takes a long time to construct, and is inconvenient to install and use. Therefore, in view of the above phenomenon, a benchmark structure for surveying and mapping of water conservancy projects is proposed to meet the needs of actual use. Utility Model Content

[0010] Preferably, the cleaning assembly floats on the water surface, and one end of the cleaning bristles fits against the surface of the pole body.

[0011] Compared with the related art, the benchmark structure for water conservancy engineering surveying and mapping provided by the utility model has the following beneficial effects:

[0012] The utility model provides a benchmark structure for water conservancy engineering surveying and mapping.

[0013] The utility model provides a benchmark structure for water conservancy engineering surveying and mapping. The cleaning component floats on the water surface. Firstly, the water level can be indicated to facilitate observation of the water level. Secondly, the floating ring can be rotated under the action of wind or water flow on the blades.

[0020] Example, by Figure 1-5 The utility model comprises a cement base 1, a vertical pole 2 is fixedly installed in the middle of the cement base 1, a benchmark body 3 is movably sleeved on the upper part of the vertical pole 2, a cleaning component 4 is movably sleeved on the surface of the benchmark body 3, and a digital mark 5 and a water level mark 6 are printed on the surface of the benchmark body 3.

[0021] In this embodiment, the digital mark 5 and the water level mark 6 are made of reflective material and are clearly visible at night. Figure 1 The water level mark 6 between the two "1"s is used as the 0 scale line and is installed flush with the water surface so that changes in the water level can be observed at any time; wherein, the cleaning component 4 can be used to clean the surface of the benchmark body 3 to prevent the surface of the benchmark body 3 from being contaminated and affecting observation.

[0022] A connecting column 21 is fixedly installed on the top of the vertical pole 2, a threaded column 22 is fixedly installed on the top of the connecting column 21, an extrusion sleeve 23 is threadedly connected to the surface of the threaded column 22, and a cross groove 24 is opened on the top of the extrusion sleeve 23.

[0023] In this embodiment, after the pressing sleeve 23 rotates, the pressing sleeve 23 moves up and down relative to the threaded column 22 .

[0024] The extrusion sleeve 23 is truncated cone-shaped.

[0025] In this embodiment, the extrusion sleeve 23 is made of a relatively soft material and can be deformed. Figure 5 As shown, when the threaded column 22 is above the extrusion sleeve 23, the upper end of the extrusion sleeve 23 expands outward under the extrusion of the threaded column 22 so that the extrusion sleeve 23 fits the inner wall of the pole body 3, thereby completing the relative fixation of the extrusion sleeve 23 and the pole body 3. When the threaded column 22 is below the extrusion sleeve 23, the extrusion sleeve 23 can move up and down in the pole body 3. The above can be used to adjust the height position of the pole body 3, thereby determining the water level standard.

[0026] A limiting groove 25 is formed on the side of the extrusion sleeve 23 , and a limiting rib 26 is integrally formed on the inner wall of the pole body 3 . The extrusion sleeve 23 is movably installed inside the pole body 3 through the limiting groove 25 .

[0027] In this embodiment, the extrusion sleeve 23 can be limited by the cooperation of the limiting rib 26 and the limiting groove 25 while the pole body 3 is rotated, so that the extrusion sleeve 23 rotates simultaneously with the pole body 3. As long as the pole body 3 is out of the water, the height of the pole body 3 can be adjusted by rotating the pole body 3.

[0028] The cleaning assembly 4 comprises a floating ring 41, a blade 42 is fixedly mounted on the side of the floating ring 41, and the blade 42 is arc-shaped, and a cleaning bristle 43 is fixedly mounted on the inner wall of the floating ring 41. The cleaning assembly 4 floats on the water surface, and one end of the cleaning bristle 43 fits the surface of the pole body 3.

[0029] In this embodiment, the cleaning component 4 floats on the water surface. First, it can indicate the water level to facilitate observation of the water level. Secondly, under the action of wind or water flow on the blades 42, the floating ring 41 can rotate. While the floating ring 41 rotates, the cleaning brush 43 is used to clean the surface of the benchmark body 3, thereby ensuring the observation effect of the benchmark body 3.

[0030] Working principle: By rotating the benchmark body 3, the extrusion sleeve 23 can be driven to rotate, so that the friction between the extrusion sleeve 23 and the inner wall of the benchmark body 3 becomes smaller, and the position of the benchmark body 3 can be adjusted, which is convenient for the installation and position adjustment of the benchmark body 3; in addition, the cleaning component 4 floats on the water surface, firstly, it can indicate the water level, which is convenient for observing the water level, and secondly, it can also rotate the floating ring 41 under the action of wind or water flow on the blades 42. While the floating ring 41 rotates, the cleaning brush 43 is used to clean the surface of the benchmark body 3, thereby ensuring the observation effect of the benchmark body 3.
