Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring tool technology, specifically to a transdermal oil penetration depth measuring instrument. Background Technology
[0002] In highway construction, a crucial step to ensure the pavement quality meets usage requirements is the penetration of a tack coat. The "Specifications for Field Testing of Highway Subgrade and Pavement" (JTG3450-2019) specifies the testing procedures for the penetration depth of the tack coat. The existing method for measuring the penetration depth involves using a ruler and protractor. The surveyor measures the penetration depth along the circumference of the drilled hole at eight evenly spaced intervals, estimating the depth to 0.5 mm, and denoteing the result as di (i = 1, 2, ..., 8). This method has a drawback: it's difficult for the surveyor to observe the ruler readings inserted into the drilled hole, and because each hole requires eight measurements, the measurement efficiency is low.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-2 This utility model provides a technical solution: a permeable oil penetration depth measuring instrument, comprising a cylindrical main body 1 and a positioning cylinder 5, in accordance with the "Highway Subgrade and Pavement Field Testing Procedures".
[0016] JTG3450-2019 specifies that the diameter of the drilled hole should be 100mm or 150mm, and the drilled hole depth should not be less than 50mm. Therefore, the diameter of the positioning cylinder 5 is 95-99mm or 145-149mm, which is convenient for insertion into the drilled hole without leaving large gaps to ensure measurement accuracy. The height should not be less than 60mm, so that the permeation layer is completely exposed for imaging by the camera module 4. The inner wall of the positioning cylinder 5 is provided with a longitudinal reference scale line 10, which is located at the edge of the imaging window 9, so that the measured value of the permeation depth can be easily read from the reference scale line 10 in the photograph. The top surface of the main body 1 is provided with a display module 3, which is used to display the captured content, so that the measuring personnel can easily read the measured value of the permeation depth from the captured photograph. The main body 1 records measurement data. A camera module 4 is installed at the bottom of the main body 1. The camera module 4 is equipped with a protective cover 12 to protect the camera module 4. A battery 2 is installed inside the main body 1. The display module 3 and the camera module 4 are both electrically connected to the battery 2. The display module 3 and the camera module 4 are electrically connected. The power button, charging interface and shooting button and other conventional components of this measuring instrument are not shown in the figure. A clamping part 7 is provided at the lower part of the main body 1. The positioning cylinder 5 is adjustablely connected to the clamping part 7 through the fixing ring 6 and the fastening screw 11. The height of the camera module 4 can be adjusted by loosening the fastening screw 11 so that it can more clearly shoot the seepage part of the inner wall of the drilled hole. The side of the positioning cylinder 5 has eight equally angled shooting windows 9.
[0017] Example 1
[0018] The camera module 4 integrates eight cameras arranged in an equal-angle array, with each camera corresponding to one of the eight image capture windows 9. In use, the positioning cylinder 5 is inserted into the borehole to be measured, and the camera module 4 is activated. The eight cameras capture eight images of eight equally divided sections of the borehole's inner wall. These images are then used to read the eight penetration depth measurements using the reference scale 10. Alternatively, the images can be imported into a computer and automatically calculated using a fixed scaling ratio.
[0019] Example 2
[0020] The camera module 4 has only one camera. The clamping part 7 is equipped with eight positioning slots 8 arranged in an equal-angle array. The eight positioning slots 8 correspond one-to-one with the eight photo windows 9. In use, the positioning cylinder 5 is inserted into the drilled hole to be measured. The fastening screw 11 is aligned with one of the positioning slots 8 and tightened. The camera module 4 is then activated to take the first picture of the eight equally divided positions on the inner wall of the drilled hole. The fastening screw 11 is then loosened, the main body 1 is rotated, and the other positioning slot 8 is aligned with the fastening screw 11. The fastening screw 11 is then tightened and the second picture of the eight equally divided positions on the inner wall of the drilled hole is taken. The above operation is repeated to take eight pictures. The eight measured values of the penetration depth are read with reference to the scale line 10, or the data can be imported into a computer and the eight measured values of the penetration depth can be automatically calculated using a fixed scaling ratio of the photos.
