[0025] The specific setting and function of fixed connecting device 2 and stable support device 3 are described below.

[0026] In the embodiment, fixed connecting device 2 includes adjust fastener 21 that is screwed on the inner wall of threaded hole 11, the outer wall of adjust fastener 21 is screwed with rotating connecting plate 22, and rotating connecting plate 22 and support plate 1 are screwed through adjust fastener 21.

[0027] The effect reached by the above-mentioned component is that: through the rotation of adjust fastener 21, the angle and fastening degree between rotating connecting plate 22 and support plate 1 can be flexibly changed, and the measurement work of level gauge in each direction can be realized.

[0028] Specifically, the top of rotating connecting plate 22 is fixedly connected with support bend plate 23, and the both sides of support bend plate 23 are provided with connecting hole 24.

[0029] The effect achieved by the above-mentioned components is that the support bent plate 23 provides a stable support platform for the level device 29, and the unique curved shape can disperse the gravity of the level device and enhance stability.

[0030] Specifically, the inner wall of the connecting hole 24 is threadedly connected with an adjuster 25, the top of the adjuster 25 is rotationally connected with a bearing 26, the outer surface of the bearing 26 is fixedly connected with an arc-shaped positioning plate 27, and the bearing 26 is embedded in the outer surface of the arc-shaped positioning plate 27.

[0031] The effect achieved by the above-mentioned components is that the adjuster 25 can adjust the distance between the arc-shaped positioning plate 27 and the level device 29 by rotating, so that the arc-shaped positioning plate 27 can be accurately positioned and fixed according to the shape of the level device 29, and better fit the contour of the level device 29.

[0032] Specifically, the inner wall of the arc-shaped positioning plate 27 is fixedly connected with an anti-skid rubber pad 28, the arc-shaped positioning plate 27 is symmetrically arranged on both sides of the support bent plate 23, and the arc-shaped positioning plate 27 is clampedly connected with the level device 29.

[0033] The effect achieved by the above-mentioned components is that the anti-skid rubber pad 28 is made of special rubber material, has high friction and good wear resistance, and can effectively prevent the level device 29 from sliding during use.

[0034] Specifically, the stable support device 3 comprises a connecting plate 31 fixedly connected to the outer surface of the support plate 1, and a rotating shaft 32 rotationally connected in the connecting plate 31.

[0035] The effect achieved by the above-mentioned components is that the rotating shaft 32 enables the telescopic support leg 33 to rotate flexibly relative to the connecting plate 31, which facilitates adjusting the angle of the support leg according to the actual situation of the ground in different construction scenes, so as to ensure good contact with the ground.

[0036] Specifically, the outer surface of the rotating shaft 32 is fixedly connected with a telescopic support leg 33, the outer surface of the telescopic support leg 33 is threadedly connected with a limiting piece 34, and the telescopic support leg 33 is arranged at a trisection distance on the outer surface of the support plate 1.

[0040] Working principle: when installing the level gauge, first place the support plate 1 at the appropriate position, then adjust the angle of the rotating connecting plate 22 by rotating the adjusting fastener 21, so that it matches the installation requirements of the level gauge, then tighten the adjusting fastener 21 to fix the rotating connecting plate 22 on the support plate 1, then place the level gauge device 29 on the support curved plate 23, adjust the distance between the arc-shaped positioning plate 27 and the level gauge device 29 by rotating the adjuster 25, so that the arc-shaped positioning plate 27 can tightly fit the shell of the level gauge device 29, and the anti-skid rubber pad 28 increases the friction force to ensure firm fixation of the level gauge.

[0041] When selecting the support position, according to the ground conditions, if it is uneven ground, the construction personnel rotates the rotating shaft 32 to adjust the angle of the telescopic support leg 33 so that it is in good contact with the ground, then according to the height of the ground, stretches or shrinks the telescopic support leg 33 to adjust the level gauge to the horizontal state, then tightens the limiting piece 34 to fix the length of the telescopic support leg 33, if it is soft ground, installs the ground cone 36 on the bottom of the telescopic support leg 33 through the bolt 35, rotates the bolt 35 to make the ground cone 36 penetrate into the ground to provide more stable support for the level gauge, during the whole measurement process, the fixed connecting device 2 ensures stable connection of the level gauge and the support plate 1, and the stable support device 3 provides stable support according to different ground conditions, so as to ensure that the level gauge can accurately measure and reduce the measurement error caused by unstable installation and support.
