DETAILED DESCRIPTION

[0017] The utility model is described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1 and 2 As shown, a sludge thickness measuring device comprises a measuring rod 1 and a support rod 2, wherein the support rod 2 is provided with a first end 21 and a second end 22 for contacting sludge, wherein a cavity penetrating the first end 21 and the second end 22 is provided inside the support rod 2, wherein the measuring rod 1 is partially coaxially slidably located in the cavity, wherein the measuring rod 1 is provided with a scale 7 along the length direction, and in the initial state, the measuring rod 1 and the support rod 2 are fixed by a pin 3. In the initial operation, the support rod 2 is vertically placed on the sludge, and the second end 22 of the support rod 2 is in contact with the sludge. Since the density of the sludge is large and it has a certain surface tension, the sludge will not enter the cavity through the second end 22. After the support rod 2 is placed, the pin 3 is pulled out, and the measuring rod 1 is lowered along the cavity until the measuring rod 1 is inserted into the sludge. The staff member presses the measuring rod 1 hard until the measuring rod 1 touches the bottom of the sludge. At this time, the scale 7 degrees at the intersection of the measuring rod 1 and the first end 21 of the support rod 2 is the thickness of the sludge at this point. The device has a simple structure, low cost, and can quickly and accurately complete the sludge thickness measurement.

[0019] In this embodiment, if Figure 1 As shown, a bottom bracket 23 is provided on the outer peripheral wall of the second end 22 of the support rod 2, and the diameter of the bottom bracket 23 is larger than the diameter of the support rod 2. The bottom bracket 23 increases the contact area between the second end 22 and the silt surface, so that the support rod 2 is located on the silt surface during the silt detection process.

[0020] In this embodiment, if Figure 1 As shown, a bracket 4 is vertically provided on the outer wall of the support rod 2 near the first end 21, and a pendant 5 is suspended on the end of the bracket 4 away from the support rod 2. The bracket 4 is vertically arranged with the support rod 2, so that the pendant 5 is parallel to the support rod 2 under the action of gravity, ensuring that the support rod 2 is in a vertical state.

[0021] In this embodiment, if Figure 1 As shown, the measuring rod 1 comprises a descending section 11 and a measuring section 12 integrally formed with the descending section 11, the descending section 11 is located in the cavity, and the length of the descending section 11 is the same as the length of the support rod 2, and the measuring section 12 is provided with a scale 7. It is ensured that in the initial state, the end of the descending section 11 is against the silt surface.

[0022] In this embodiment, if Figure 2 As shown, the measuring section 12 is provided with a first screw hole in the radial direction at one end close to the descending section 11, and the first end 21 is provided with a second screw hole in the radial direction. The aperture of the first screw hole is the same as the aperture of the second screw hole, and the pin rod 3 is a screw rod threadedly matched with the first screw hole and the second screw hole. In the initial state, the screw rod passes through the first screw hole and the second screw hole to fix the measuring rod 1 in the supporting rod 2. When measuring, the screw rod is pulled out to make the descending section 11 descend and insert into the silt. The height of the descending section 11 and the measuring section 12 is the thickness of the silt.

[0023] In this embodiment, if Figure 1 As shown, the end of the descending section 11 away from the measuring section 12 is in a pointed cone shape. The pointed cone shape is conducive to the descending section 11 being inserted into the mud.

[0024] In this embodiment, if Figure 1 As shown, the outer wall of the support rod 2 is provided with a placement piece 6 for placing the pin rod 3. After the staff pulls out the pin rod 3, the pin rod 3 can be placed in the placement piece 6 for easy taking.

[0025] In this embodiment, if Figure 3As shown, the scale 7 includes a numerical value 71 and a mark 72 corresponding to the numerical value 71, and the numerical value 71 gradually increases from the end close to the descending section 11 to the end far from the descending end. The distance that the descending section 11 descends with the measuring section 12 is the thickness of the sludge, and the numerical value 71 at the intersection of the measuring section 12 and the support rod 2 is the thickness of the sludge. The mark 72 in this embodiment is an "E" type engraving method that is more eye-catching and easy to read accurately and quickly under adverse conditions.
