In the utility model, the ruler is inserted into the fixed slot, and then the knob is turned to make the movable slot cooperate with the fixed slot to clamp the ruler, and then the ruler can be upright by holding the handle. The verticality of the ruler can be ensured by observing the circular level bubble, which can ensure the auxiliary standing effect of the ruler and greatly reduce the measurement error. However, the existing ditch depth measuring device is not convenient to be installed and fixed for measurement on the side of a muddy ditch or a ditch with a poor road surface.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown:

[0026] A land surveying and measuring tool is disclosed in CN215522521U. The ruler is inserted into a fixed slot, and then a knob is turned to make the movable slot cooperate with the fixed slot to clamp the ruler. Then, the ruler can be upright by holding the handle. The verticality of the ruler can be ensured by observing the circular level bubble, and the auxiliary uprighting effect of the ruler can be ensured, which greatly reduces the measurement error. However, the existing ditch depth measuring device is not convenient to be installed and fixed for measurement on the side of a muddy ditch or a ditch with a poor road surface. At the same time, the operation is complicated when measuring the depth of a continuous ditch, and the measurement efficiency is low. On this basis, an anti-collision measuring mechanism 1 is added.

[0027] like Figure 1 , Figure 2 and Figure 5 As shown:

[0028] In an optional embodiment: the anti-collision measuring mechanism 1 includes an alloy tripod 11, a level body 12, a support frame 13, a sliding seat 14, an upper motherboard 15 and a lower motherboard 16. The top of the alloy tripod 11 is threadedly connected to the surface of the level body 12, the support frame 13 is fixedly connected to the outer side of the alloy tripod 11, the sliding seat 14 is threadedly sleeved on the inner side of the support frame 13, the upper motherboard 15 is threadedly connected to the inner side of the sliding seat 14, and the lower motherboard 16 is slidably sleeved inside the upper motherboard 15. A stepper motor 4, a threaded rod 5 and a linear shaft 6 are also arranged inside the support frame 13. The motor shaft of the stepper motor 4 is fixedly connected to one end of the threaded rod 5 through a coupling. The linear shaft 6 passes through the interior of the sliding seat 14 and is fixedly connected to the inner surface of the support frame 13. The interior of the sliding seat 14 is respectively penetrated by threaded grooves 7 and through holes 8 that match the sizes of the threaded rod 5 and the linear shaft 6.

[0029] In this embodiment: due to the complex terrain at the bottom of the ditch, when operating the device, the rod of the alloy tripod 11 can be extended into the flat ground far away from the ditch to stabilize the device. During operation, the stepper motor 4 inside the support frame 13 is started by the control end, and the stepper motor 4 drives the threaded rod 5 to rotate. The linear shaft 6 penetrates the sliding seat 14 to limit its movement path. With the screw teeth of the threaded rod 5 and the screw transmission of the built-in thread groove 7 of the sliding seat 14, the sliding seat 14 can drive the upper and lower mother plates 16 to move along the slotted horizontal plane of the through hole 8, and then the upper mother plate 15 and the lower mother plate 16 are penetrated into the water from the upstream of the ditch and gradually displaced to the deep water, thereby improving the measurement range.

[0030] More specifically:

[0031] like Figure 2 , Figure 3 and Figure 4 As shown:

[0032] In an optional embodiment: an electric telescopic rod 2 and a push rod 3 are also provided inside the lower motherboard 16, the output end of the electric telescopic rod 2 is fixedly connected to the top of the push rod 3, the bottom of the push rod 3 is fixedly connected to the middle of the top of the lower motherboard 16, and the bottom of the sliding seat 14 is also provided with a blind hole 9, a clamping plate 10 and a limit spring 20, the blind hole 9 is opened at the bottom of the sliding seat 14, the outer side of the clamping plate 10 abuts against the outer wall of the upper motherboard 15, the two sides of the limit spring 20 are respectively fixedly connected to the opposite side surfaces of the clamping plate 10 and the sliding seat 14, and a scale line 21 is also opened on one side of the upper motherboard 15 and the lower motherboard 16.

[0033] In this embodiment: as the water level gradually deepens, the electric telescopic rod 2 on the inner side of the upper motherboard 15 can be started, and its output end pushes the push rod 3, and the push rod 3 pushes the lower motherboard 16 at the bottom to extend outward from the upper motherboard 15 until it touches the riverbed. The extension and retraction of the lower motherboard 16 is flexibly controlled by electric means to effectively prevent collision; then the level body 12 provides a horizontal line of sight and can aim at the level rod for reading, which is used to measure the height difference between two points. By adding the scale lines 21 of the upper motherboard 15 and the lower motherboard 16, the depth of the water level can be accurately measured, thereby completing high-precision measurement.

[0034] It should be noted that: as the water level gradually goes deeper, the water pressure increases, and the resistance encountered when moving forward increases. At this time, the upper mother plate 15 squeezes the clamping plate 10 inward along the opening surface of the blind hole 9. Since the inner limit spring 20 is always in a compressed state, under the elastic support, the two groups of clamping plates 10 are relatively pressed against the upper mother plate 15, thereby preventing the top thread from loosening and causing the upper mother plate 15 and the lower mother plate 16 to fall.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
