A plurality of scales 12 are provided on the outer circumferential array of the measuring rod 10.
[0029] Further, such as Figure 3-8 As shown, a third slide groove 24 is provided on one side of the measuring rod 10, a second shift block 25 is provided inside the third slide groove 24 for vertical sliding, a cylinder 26 is provided inside the measuring rod 10 for vertical sliding, the third slide groove 24 is fixedly connected to the cylinder 26, a plurality of rubber protrusions 27 are provided on the outside of the cylinder 26, and each group of rubber protrusions 27 is vertically spaced outside the cylinder 26, and each rubber protrusion 27 slides in the slot 19.
[0030] Further, such as Figure 4As shown, the outer lower end and the upper end of each rubber protrusion 27 are both inclined structures.
[0031] Further, such as Figure 1 As shown, a plurality of slide plates 35 are slidably provided in a circular array on the outer side of the annular plate 21, a ring member 30 is sleeved on the outer side of the measuring rod 10, the inner side of the ring member 30 is in sliding contact with the outer side of the measuring rod 10, the ring member 30 is located above the sleeve 20, a plurality of first fixed seats 31 are fixedly provided in a circular array on the outer side of the annular member 30, a second fixed seat 32 is fixedly provided on the upper side of each slide plate 35, a connecting plate 33 is connected between each first fixed seat 31 and the second fixed seat 32, the inclined upper end of each connecting plate 33 is rotatably connected to the first fixed seat 31, and the inclined lower end of each connecting plate 33 is rotatably connected to the second fixed seat 32.
[0032] Further, such as Figure 1 As shown, two second L-shaped elastic rods 34 are fixedly provided on opposite sides of the upper end of the sleeve 20 .
[0033] Further, such as Figure 7 As shown, a spring 36 is connected between the inner side of each slide plate 35 and the inside of the annular plate 21 .
[0034] Further, such as Figure 1 As shown, a handle 29 is fixedly provided at the upper end of the measuring rod 10 , and a sponge cover 28 is provided on the outer side of the upper part of the handle 29 .
[0035] Further, such as Figure 1 As shown, the lower end of the measuring rod 10 is threadedly contacted with an end cap 37 .
[0036] When in use, the staff turns the bolt 22 clockwise, and the bolt 22 rotates through the bolt 22 and the sleeve 20 threaded contact, thereby pushing one end of the push block 23 into one of the first slide grooves 13; the staff slides down the slide ring 30, and the ring member 30 moves downward and rotates through the six connecting plates 33, while driving the six slide plates 35 to move outward, and the six slide plates 35 move outward, thereby increasing the force-bearing area of the ring plate 21, wherein the slide plates 35 slide outward, stretching the spring 36 and the spring 36 generates an elastic force; the staff pushes the two second L-shaped elastic rods 34 outward, so that the second L-shaped elastic rods 34 are bent and deformed, thereby generating an elastic force for the second L-shaped elastic rods 34, and then the staff moves the ring member 30 downward to the upper side of the sleeve 20, at this time, the staff loosens the two second L-shaped elastic rods 34, and the second L-shaped elastic rods 34 are reset under the action of the elastic force, so that the upper part of the second L-shaped elastic rod 34 is stuck on the upper side of the ring member 30, so as to limit the ring member 30 in the two second L-shaped elastic rods 34.
[0037] Secondly, the staff inserts the measuring rod 10 into the snow on the road surface. When the three support rods 11 are in contact with the road surface, the measuring rod 10 is vertical to the ground to ensure the accuracy of the measured value. The annular plate 21 slides upward along the measuring rod 10 under the influence of the resistance of the snow. The annular plate 21 moves upward through the sleeve 20 to drive one end of the push block 23 to slide in one of the first slide grooves 13. One end of the push block 23 slides in the first slide groove 13 and contacts the first shift block 16, thereby driving the arc slide 15 to slide upward in the second slide groove 14. When the lower end of the first shift block 16 contacts one end of the push block 23, the lower end of the arc slide 15 is flush with the lower end of the annular plate 21. According to the scale 12 position corresponding to the lower end of the arc slide 15 after the arc slide 15 slides in the second slide groove 14, the thickness of the snow on the road surface can be measured.
[0038] When the curved slide 15 slides upward in the second slide groove 14, the curved slide 15 moves upward and drives the block 18 to move upward through the first L-shaped elastic rod 17. The block 18 moves upward through the upper part of the block 18 and the upper end contact surface of the slot 19 is an inclined surface, so that the first L-shaped elastic rod 17 is bent and deformed outward, so that the curved slide 15 can move upward freely in the second slide groove 14; when the curved slide 15 stops moving, the lower part of the block 18 and the lower end contact surface of the slot 19 are flat, so as to prevent the curved slide 15 from moving downward in the second slide groove 14, thereby playing a one-way limiting effect on the curved slide 15, preventing the curved slide 15 from moving downward, and avoiding affecting the accuracy of the measured value.
[0039] Next, when the staff has finished measuring a position, the staff will perform a second measurement at a position more than 10m away from the position. The staff will turn the bolt 22 counterclockwise to make the bolt 22 drive one end of the push block 23 to disengage from one of the first chutes 13; the staff will turn the sleeve 20 to make one end of the push block 23 correspond to the other first chutes 13, and the staff will turn the bolt 22 clockwise to make one end of the push block 23 enter the other first chutes 13, so that the measuring rod 10 is inserted into the snow on the road surface for measurement; the snow depth at multiple positions is measured according to the above operation. At this time, the three arc-shaped slides 15 in the three second chutes 14 are respectively located at the same height or different heights. The staff will slide the ring member 30 upward from the two second L-shaped elastic rods 34, so that under the elastic force of the spring 36, the slide 35 will slide inward into the annular plate 21, thereby contracting the annular plate 21.
[0040] Finally, the staff takes the measuring rod 10 indoors or in the car, records the scales 12 corresponding to the lower ends of the three arc-shaped slides 15 in the three second chutes 14, enters them into the corresponding columns of the observation book, and calculates the average value. The staff rotates the end cover 37 clockwise to remove the end cover 37 from the lower end of the measuring rod 10, so as to pour out the snow that has entered the measuring rod 10. The staff rotates the end cover 37 counterclockwise to install the end cover 37 on the lower end of the measuring rod 10; then the staff moves the second dial block 25 to move downward in the third chute 24, and the second dial block 25 moves downward to drive the cylinder 26 to move downward in the measuring rod 10, and the cylinder 26 moves downward to drive several rubber bumps 27 to move downward; wherein, the outer upper end and lower end of the rubber bump 27 are both inclined structures to cooperate with the elastic force of the rubber bump 27, so that the cylinder 26 can move up and down smoothly in the measuring rod 10. When the cylinder 26 moves downward to the position corresponding to the three blocks 18, the rubber protrusion 27 presses the blocks 18 outward, so that the first L-shaped elastic rod 17 is bent and deformed, and the blocks 18 are disengaged from the slots 19, so that the arc-shaped slide plate 15 can slide downward in the second slide groove 14. The cylinder 26 moves downward to cooperate with the rubber protrusion 27 to press the blocks 18, so that the blocks 18 are disengaged from the slots 19, so that the arc-shaped slide plate 15 can slide downward in the second slide groove 14, and the arc-shaped slide plate 15 slides back to its original position, so that the snow depth of other parts of the road surface can be measured.
[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the appended claims and their equivalents.
