Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1:

as shown in fig. 1, 2, 3, 4, 6, the utility model provides a vertical slope detection device of hydraulic structure upstream face, including leveling base 1, the horizontal beam body 2, locating lever 3 and dipperstick 4. The leveling base 1 is used as a basic supporting structure, the horizontal beam body 2, the positioning rod 3, the measuring scale 4 and the upstream face of the wharf front edge structure to be measured form a closed right trapezoid, and after the three edges of the right trapezoid are obtained through measurement, the length and the inclination angle of the inclined edge of the right trapezoid can be calculated. The height of the positioning rod 3 can be fixed by the detection device, and the measuring scale 4 and the positioning rod 3 are combined for fixing; not only the error caused by high floating is avoided, but also the error caused by floating of the manual holding measuring scale 4 on the traffic boat is avoided. The measurement accuracy is greatly improved.

The leveling base 1 serves as a stable foundation of the device, can be fixedly installed on a pile body, a wall body or any fixing structure at the front edge of a wharf, and provides a stable supporting effect for the whole detection device. The leveling base 1 uses the installation base 11 as a main carrier, if the installation base 11 is a rectangular plate, the installation holes 12 are opened at the edges of four corners of the installation base, and are connected and fixed through the adjusting bolts 13. A leveling bubble is arranged on the top surface of the mounting seat 11, so that the levelness of the leveling base 1 can be visually observed. If the leveling base 1 is observed not to be horizontal, the adjusting bolt 13 can be screwed/unscrewed, and the distance between any one of the four top angles of the mounting seat 11 of the rectangular plate body and the fixed structure is changed, so that the levelness of the whole leveling base 1 is adjusted.

Since the conventional chute 22 structure can only restrict two degrees of freedom of the positioning rod 3 swinging in both sides perpendicular to the moving direction, the positioning rod 3 cannot be restricted from falling. Therefore, the inner side wall of the sliding groove 22 is further provided with a limiting groove 23, so that the sliding groove 22 and the limiting groove 23 are combined to form a cross-shaped groove or a T-shaped groove. Because the cross-shaped groove has better constraint effect on the vertical long rod, the cross-shaped groove is adopted in the embodiment.

Or a plurality of middle rod bodies 34 are adopted to carry out end-to-end connection of successive lengths one by one, so as to achieve the required total length. The upper rod 32 does not need to be replaced because its cross-shaped configuration is not adjusted, and likewise the lower rod 33 does not need to be replaced because of the installation of the measuring scale 4. The manufacturing cost and the material loss of the positioning rod 3 can be reduced.

Example 2:
