At present, there is no scientific detection method for the cross-sectional dimensions of drainage ditches. When detecting the cross-sectional dimensions of drainage ditches, the detection personnel use steel tape measures to directly measure the top width and bottom width of the cross-sectional dimensions of the drainage ditch. They do not consider whether the steel tape measure is parallel to the cross-sectional dimensions of the drainage ditch during the measurement process. When measuring the depth of the cross-sectional dimensions of the drainage ditch, they do not consider whether the steel tape measure is perpendicular to the horizontal plane during the measurement process. There are large errors in the detection process, resulting in inaccurate and inaccurate detection results.

[0003] In order to solve the problems currently encountered by testing units in the process of testing the cross-sectional dimensions of drainage ditches, it is necessary to develop a testing device for the cross-sectional dimensions of drainage ditches to improve the accuracy of testing the cross-sectional dimensions of drainage ditches and improve the work efficiency of testing personnel.

[0019] like Figures 1 to 6As shown, a drainage ditch cross-sectional dimension detection device comprises a ruler 1, a lifting and adjusting mechanism and a distance measuring mechanism, the lifting and adjusting mechanism is provided with two and is slidably connected to both sides of the ruler 1, the distance measuring mechanism is located on the inner side of the lifting and adjusting mechanism and is slidably connected to the bottom of the ruler 1, the ruler 1 is a hollow structure with an opening at the bottom, a bidirectional screw 2 is rotatably connected inside the ruler 1, and the threads on both sides of the bidirectional screw 2 are opposite, one end of the bidirectional screw 2 passes through the inner wall of the ruler 1 and is fixedly connected to a crank 3, both sides of the bidirectional screw 2 are threadedly connected to sliders 4 and the two sliders 4 are symmetrically distributed, the two sliders 4 are slidably matched with the inner wall of the ruler 1, and the distance measuring mechanism is provided with two and is slidably connected to the bottom of the two sliders 4 respectively.

[0020] The lifting and lowering adjustment mechanism includes a column 5, a base 6, a sleeve 7, a clamping piece 8 and a locking bolt 9. The column 5 is vertically connected to the base 6, the sleeve 7 is slidingly mounted on the column 5, the clamping piece 8 is arranged on one side of the sleeve 7, and the other side of the sleeve 7 is fastened to the column 5 by the locking bolt 9, wherein the inner end of the locking bolt 9 is pressed against the outer surface of the column 5, and at this time, the position of the sleeve 7 on the column 5 is limited by the action of friction force; the ruler 1 is slidably installed in the clamping piece 8 of the two sleeves 7.

[0021] The distance measuring mechanism includes a laser distance meter 10, a sliding member 11 and a pointer 12. The sliding member 11 is arranged on the top of the laser distance meter 10. A sliding groove 13 slidably matched with the sliding member 11 is arranged inside the bottom side of the slider 4. The pointer 12 is arranged on one side of the laser distance meter 10. The pointer 12 points to the scale line on the ruler 1. The sliding member 11 is a T-shaped structure, including a horizontal beam and a vertical beam. A groove is arranged on both sides of the vertical beam and at the lower edge of the horizontal beam, so that the distance measuring mechanism can slide more smoothly in the sliding groove 13, thereby improving the distance measuring accuracy.

[0022] Level bubbles 14 are provided at both ends of the ruler 1, which can be adjusted to keep the ruler on a horizontal plane during measurement. The scale at the center of the ruler is zero, and the scale increases toward both ends, which is conducive to reading and does not require excessive adjustment of the ruler to waste time.

[0023] The working process and principle of the utility model are:

[0024] The specification of the ruler in a trapezoidal drainage ditch cross-section dimension detection device is 2m. The first step is to install the device: place the device on both sides of the drainage ditch, adjust the sliding sleeve 7 to a position that is convenient for the inspector to read, adjust the bolt 9 through the level bubble 14 so that the ruler 1 is always on the horizontal plane, and fix the position of the sliding sleeve 7 through the locking bolt 9. The second step is data collection: turn on the laser rangefinder 10, shake the remote handle 3, and use the bidirectional screw 2 to make the sliders 4 move closer or farther from each other, and then slide the distance measuring mechanism so that the laser point is aligned with the top width of the drainage ditch. The sides overlap, the readings of ruler 1 are X1 and X2, and the readings of laser rangefinder 10 are a1 and a2, so that the laser point coincides with the bottom width of the drainage ditch, the readings of ruler 1 are Y1 and Y2, and the readings of laser rangefinder 10 are b1 and b2. The third step is data analysis: detect the top width, bottom width and depth of the drainage ditch cross-section; top width = Y1 + Y2; bottom width = X1 + X2; depth = (a1 + a2-b1-b2) / 2. Similarly, the cross-sectional dimensions of U-shaped and rectangular drainage grooves can be measured.
