Summary of the invention:
The purpose of this utility model is the shortcoming overcoming prior art to exist, and seeking design provides a kind of measurement apparatus for underwater structure surface smoothness, solves the technical barrier that all kinds of underwater structure flatness are difficult to measure.
To achieve these goals, the measurement apparatus agent structure for underwater structure surface smoothness that this utility model relates to includes measurement frame, measuring stick, measured hole and fastening screw, the bottom of the measurement frame of hollow type metal framework structure offers the measured hole of more than one equal diameters, each measured hole is provided with the fastening screw for fixation measuring rod that can tighten or loosen, with carrying out the numbering of layout according to the incremental arithmetic progression that tolerance is 1 in each measuring stick, the number of measuring stick is more than the number of measured hole；The shape of measurement frame determines with size according to the surface configuration of works to be measured with size, measuring stick is to wait the pin bundle formula club shaped structure of long structure, the diameter of measured hole is more than the diameter of measuring stick so that measuring stick can be assigned in measured hole, and each measuring stick is stretched out the value bottom measured hole and is the point value of works surface smoothness to be measured.
This utility model is compared with prior art, the measuring stick using sheet metal and nylon or quality of rubber materials matches, achieve the visual simulation to underwater structure surface to measure, by collecting the measuring stick overhanging value in measured hole thus the intuitive and accurate curve form drawing underwater structure surface；This apparatus structure is simple, novel in design, with low cost, makes easily, it is simple to use.
Accompanying drawing illustrates:
Fig. 1 is the planar body structural representation of the measurement apparatus for underwater structure surface smoothness that this utility model relates to.
Fig. 2 is the A-A section Main Structural Section schematic diagram of the measurement apparatus for underwater structure surface smoothness that this utility model relates to, including works 5 to be measured.
Detailed description of the invention:
Below in conjunction with the accompanying drawings and by embodiment this utility model is described in further details, but this utility model is not limited to implementation below.
Embodiment 1:
The measurement apparatus agent structure (as shown in Figure 2) for underwater structure surface smoothness that the present embodiment relates to includes measurement frame 1, measuring stick 2, measured hole 3 and fastening screw 4, the bottom of the measurement frame 1 of hollow type metal framework structure offers the measured hole 3 of more than one equal diameters, each measured hole 3 is provided with the fastening screw 4 for fixation measuring rod 2 that can tighten or loosen, with carrying out the numbering of layout according to the incremental arithmetic progression that tolerance is 1 in each measuring stick 2, the number of measuring stick 2 is more than the number of measured hole 3；The shape of measurement frame 1 determines with size according to the surface configuration of works to be measured with size, measuring stick 2 is to wait the pin bundle formula club shaped structure of long structure, the diameter of measured hole 3 is more than the diameter of measuring stick 2 so that measuring stick 2 can be assigned in measured hole 3, and each measuring stick 2 is stretched out the value bottom measured hole 3 and is the point value of works surface smoothness to be measured.
