Description

Technical Field

[0001] The utility model belongs to the technical field of sludge depth monitoring, and in particular relates to a sludge depth monitoring device. Background Art

[0002] Silt refers to clay soil deposited in a still water or slow-flowing water environment with a natural moisture content greater than the liquid limit and a natural porosity greater than 1.0, and its particle size is less than 0.03 mm.

[0003] In the prior art, a rod with a sharp lower end is generally used. When measuring, the rod is vertically inserted into the river or pool until the lower end passes through the silt layer and abuts against the bottom of the river or pool. Since the silt will adhere to the outer surface of the rod, after taking out the rod, the position area of ​​the silt on the rod is observed to obtain the silt depth.

[0004] However, the silt does not adhere very well to the outer surface of the rod. When the rod is taken out of the river or pool, the water flow will wash away the silt traces attached to the outer surface of the rod, resulting in the silt depth data can only be estimated by the measurer, which is very inaccurate. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a sludge depth monitoring device.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A sludge depth monitoring device comprises a mounting plate, a support plate is arranged on one side of the mounting plate, a fixing sleeve is arranged above the support plate, a measuring rod is passed through the center positions of the fixing sleeve and the support plate, and a top supporting plate for installing a laser rangefinder is arranged at the upper end of the measuring rod;

[0008] A slide plate is provided on the outside of the measuring rod and below the support plate, a water storage tank is provided on the outside of the slide plate, and a pull ring is provided on one side above the slide plate, which is connected to a slider inside the measuring rod through a connecting rope.

[0009] Furthermore, an opening is provided on one side of the fixing sleeve and the supporting plate, and a clamping plate is provided on the outer side of the measuring rod facing the opening, so that the measuring rod will not be blocked when it descends, and a slot for placing a connecting rope is also provided in the clamping plate, which can reduce the influence of foreign objects on the connecting rope during operation.

[0010] Furthermore, a groove for a clamping plate to pass through is provided on the inner side of the slide plate, so that the slide plate will not rotate when it moves up and down due to the obstruction of the clamping plate, thereby preventing the connecting rope from being entangled with the device.

[0011] Furthermore, a fixing bolt for fixing the measuring rod is provided on one side of the fixing sleeve.

[0012] Furthermore, the measuring rod is a hollow tube with a conical block at the lower end. The hollow tube can reduce the weight of the measuring rod itself, making it easier to use, while the conical block at the lower end can make it easier to insert the measuring rod into the mud.

[0013] Furthermore, a plurality of water inlet holes are provided above the water tank, a drainage hole is provided on one side of the water tank, and a water plug is installed at the drainage hole. When the water tank is full of water, the slide plate will sink, and when the water plug is opened, the water in the water tank can be discharged.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, a measuring rod, a slide plate and a slider are provided. After the measuring rod is inserted into the bottom of the silt, the slide plate falls on the top of the silt. The moving distance of the slider is detected by a laser rangefinder to know the depth of the silt. The detection result is more accurate. The connecting rope can be kept in a relatively tight state under the pulling of the slide plate and the slider, so as to avoid the influence of water flow shaking on it.

[0016] The utility model can be installed on the outside of the hull through the mounting plate, and can be moved to different points to detect the depth of the silt, so as to better monitor the silt depth at different positions in the river or lake. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] As attached Figure 1-8 shown.

[0029] A silt depth monitoring device comprises a mounting plate 1 which can be mounted on a ship body, a support plate 2 is arranged on one side of the mounting plate 1, a fixing sleeve 3 is arranged above the support plate 2, an opening for a measuring rod 5 to pass through is arranged in the center of the fixing sleeve 3 and the support plate 2, an opening is arranged on one side of the fixing sleeve 3 and the support plate 2, and a clamping plate 51 is arranged on the outer side of the measuring rod 5 facing the opening.

[0030] A fixing bolt 4 for fixing the measuring rod 5 is provided on one side of the fixing sleeve 3 .

[0031] The measuring rod 5 is a hollow tube, a conical block is provided at the lower end of the measuring rod 5 , and a top support plate 52 for mounting the laser rangefinder 6 is provided at the upper end of the measuring rod 5 .

[0032] A slide plate 7 is provided on the outside of the measuring rod 5 and below the support plate 2, a groove for the card plate 51 to pass through is provided on the inner side of the slide plate 7, a water storage tank 71 is provided on the outside of the slide plate 7, a plurality of water inlet holes 72 are opened above the water storage tank 71, a drainage hole is provided on one side of the water storage tank 71, and a water plug 74 is installed at the drainage hole.

[0033] A pull ring 73 is provided above the slide plate 7 and on one side of the groove. The pull ring 73 is connected to the slider 9 located inside the measuring rod 5 through a connecting rope 8. When the water storage tank 71 outside the slide plate 7 is filled with water, the slide plate 7 will sink. Since the weight of the slide plate 7 is greater than the weight of the slider 9, the sinking of the slide plate 7 will drive the slider 9 to rise inside the measuring rod 5. The descending distance of the slide plate 7 is equal to the rising distance of the slider 9. When the slide plate 7 is located at the lower end of the measuring rod 5, the slider 9 is at the uppermost end inside the measuring rod 5, and vice versa.

[0034] Therefore, after loosening the fixing bolt 4, the staff can manually insert the measuring rod 5 into the sludge, and then fill the water storage tank 71 outside the slide plate 7 with water, and the slide plate 7 will descend and finally fall on the surface of the sludge without sinking into the sludge;

[0035] The slide plate 7 descends, and the slider 9 rises a corresponding distance inside the measuring rod 5. Then, the distance between the sliders 9 is detected by the laser rangefinder 6, and the depth of the silt is obtained.

[0036] When measuring the silt depth, the measuring rod 5 will descend deeply into the silt, so the staff operates the laser rangefinder 6 to detect the distance between it and the slider 9, and the measurement result can be viewed in the laser rangefinder 6.

[0037] When the detection is completed, the staff can retract the measuring rod 5 by pulling it upwards, and the position of the measuring rod 5 can be fixed by the fixing bolt 4; after the measuring rod 5 is pulled back, the slide plate 7 can be pulled out of the water surface by the connecting rope 8, and moved to the next monitoring point for continued use without draining the water in the water tank 71.

[0038] When all the detection work is completed, the water in the water storage tank 71 can be drained by opening the water plug 74.

[0039] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
