Abstract
Description
Technical Field
[0001] The utility model relates to the field of engineering surveying tools, in particular to a gradient meter for water conservancy projects that can be adjusted at multiple angles. Background Art
[0002] The gradient meter for water conservancy projects is a precision measuring tool used to measure and monitor the inclination angle, horizontal displacement, vertical settlement, etc. of water conservancy project structures. These data are crucial for ensuring the stability and safety of structures such as dams and levees.
[0003] When using the gradient meter, since the readings on the scale of the gradient meter are based on the premise that the scale is horizontal, it is necessary to first fit the outer shell of the gradient meter to the object to be measured, and then manually adjust the angle of the gradient meter body until the bubble in the bubble level in the gradient meter is centered. Then, read the number indicated by the pointer above the bubble level. However, it is easy to have errors when visually judging whether the bubble in the bubble level is centered, which is likely to cause deviations in the measurement results.
[0004] Therefore, in view of the above situation where the existing gradient meter needs to center the bubble in the bubble level inside the gradient meter during use, but this process requires visual judgment and is prone to errors, which is likely to cause deviations in the measurement results, a gradient meter for water conservancy projects that can be adjusted at multiple angles can be designed to solve the above problems. Summary of the Utility Model
[0005] In order to overcome the problem that during the use of the gradient meter, since the readings on the scale of the gradient meter are based on the premise that the scale is horizontal, it is necessary to first fit the outer shell of the gradient meter to the object to be measured, and then manually adjust the angle of the gradient meter body until the bubble in the bubble level in the gradient meter is centered. Then, read the number indicated by the pointer above the bubble level. However, this process requires visual judgment and is prone to errors, which is likely to cause deviations in the measurement results.

Then, press the touch switch with the index finger to connect the circuit between the dry battery and the electromagnet, so as to suck the rear turntable by the electromagnet and prevent the rear turntable and the cross pointer from rotating continuously.

Specific implementation manners
[0025] The present utility model will be further described below with reference to the drawings and embodiments.
[0026] Please refer to Figures 1-8 , the present utility model provides an embodiment: a slope gauge for water conservancy projects that can be adjusted at multiple angles, including an outer shell 1; a grip groove 2 is provided on the outer shell 1; it further includes a self-adjusting component; a slot 4 is provided at the lower end of the outer shell 1; a threaded hole 5 opened in the outer shell 1 is arranged above the rear end of the slot 4; a cushion strip 6 is slidably connected in the slot 4; the cross-sectional shape of the cushion strip 6 is "I" shaped; the rear end of the cushion strip 6 is rotatably connected with a bolt 7; the bolt 7 is in clearance fit with the threaded hole 5; a straight ruler scale 8 is provided at the lower end of the front end face of the outer shell 1.
[0027] Please refer to Figures 2-8, in this embodiment, the self-adjusting component includes a battery slot 301 opened at the upper end of the housing 1; a dry battery 302 is placed in the battery slot 301; a touch switch 303 is installed at the lower end of the battery slot 301; an electromagnet 304 is arranged at the front end of the battery slot 301; a bearing 305 is fixedly connected inside the housing 1; a plug shaft 306 is fixedly connected to the center of the bearing 305; a cross pointer 307 is fixedly connected to the front end of the plug shaft 306; a rear turntable 309 is fixedly connected to the rear end of the plug shaft 306; a scale disk 308 is arranged at the rear end of the cross pointer 307; an eccentric counterweight 310 is fixedly connected to the rear end of the rear turntable 309; the electromagnet 304 is embedded in the upper end inside the housing 1, and the electromagnet 304 is located directly above the rear turntable 309; the scale disk 308 is fixedly connected to the housing 1; both the cross pointer 307 and the rear turntable 309 are rotatably connected to the housing 1 through the bearing 305 and the plug shaft 306; the touch switch 303 is installed in the grip groove 2; the dry battery 302 is electrically connected to the touch switch 303; the touch switch 303 is electrically connected to the electromagnet 304.
[0028] When in use, after the user fits the lower end of the housing 1 to the object to be measured, the eccentric counterweight 310 will cause the cross pointer 307 and the rear turntable 309 to rotate through the plug shaft 306 and the bearing 305 until the eccentric counterweight 310 is vertically downward, so that both sides of the cross pointer 307 are kept horizontal. Then, the index finger presses the touch switch 303 to connect the circuit between the dry battery 302 and the electromagnet 304, so as to suck the rear turntable 309 by the electromagnet 304 and prevent the rear turntable 309 and the cross pointer 307 from continuing to rotate. Then, the slope instrument is taken down and the scale pointed by the cross pointer 307 on the scale disk 308 is read, thus not only avoiding the data deviation caused by the error of naked-eye observation, but also greatly improving the use convenience of the slope instrument;
[0029] When the lower end of the housing 1 is fitted to the object to be measured, if the surface of the object to be measured is pitted and not easy to fit, the bolt 7 can be loosened and the cushion strip 6 can be pulled out from the extraction slot 4, so as to increase the fitting range between the lower end of the slope instrument and the object to be measured through the cushion strip 6, so that the slope instrument is more easily fitted to the object to be measured with an uneven surface, so as to ensure the measurement accuracy.
[0030] Through the above steps, by setting the self-adjusting component, the user no longer needs to observe the bubble level with the naked eye to adjust the slope instrument body to be horizontal, but can automatically adjust the angle of the slope instrument body by gravity to keep it horizontal, and then use the electromagnet 304 to fix the slope instrument body, thus not only avoiding the data deviation caused by the error of naked-eye observation, but also greatly improving the use convenience of the slope instrument.
