Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waterway silt detection, in particular to a waterway silt depth detection device. Background Art
[0002] The main purpose of detecting the depth of silt in the waterway is to understand the actual situation of silt in the waterway and ensure the smooth and safe operation of the waterway. It provides a scientific basis for dredging. By understanding the distribution and thickness of silt, a more scientific and effective dredging plan can be formulated to improve dredging efficiency and ensure dredging effect and safety. Too much silt will block the waterway and affect the normal passage of ships. Detecting the depth of silt helps to timely discover and deal with silt problems and ensure the smooth operation of the waterway.
[0003] At present, the silt depth of the waterway is usually detected by sonar technology and probe technology. Sonar technology has the advantages of high accuracy, wide coverage area, easy operation, and is suitable for various water environments. However, sonar technology requires special equipment and professional technicians to operate, and the equipment cost may be high. Probe technology is a traditional method for monitoring silt thickness. It inserts a probe at the bottom of the predetermined water area and gradually pushes it in, and judges the thickness of the silt layer based on the detected lower surface of the silt. Probe technology has the advantages of easy operation and low cost, and it can directly contact the silt for monitoring. However, probe technology requires on-site operation and has high technical requirements for personnel.
[0004] Therefore, there is a need for a silt depth detection device that is highly economical, simple to operate, and easy to deploy in a waterway. Utility Model Content

[0025] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.
[0026] Combination Figure 1 As shown, the first aspect of the utility model proposes a channel silt depth detection device, including a limiting component 10, a floating block 20, a pull rope 30 and a supporting component 40. The limiting component 10 is connected to the bottom of the channel, and its layout position should be as close to the edge of the channel as possible. The height of the limiting component 10 is less than 0.5m.
[0027] Optional, combined Figure 2 As shown, the limiting component 10 includes a base plate 12 and a column 11. The base plate 12 is provided with a hole, and the base plate 12 can be fixed to a predetermined position at the bottom of the channel by a rivet structure. The column 11 is vertically fixed to the surface of the base plate 12. The column 11 can be optionally a cylindrical structure with a height of less than 50 cm. The floating block 20 is sleeved on the outer wall of the column 11. A limiting plate 13 is provided on the top of the column 11 for limiting the floating block 20 from escaping from the top of the column 11.
[0028] Further, the buoy 20 is set to have a density greater than water and less than silt, and the buoy 20 is sleeved on the outside of the column 11, and the buoy 20 is intended to float on the surface of the silt, which can represent the height of the silt, and the first end of the pull rope 30 is connected to the buoy 20, and the second end extends upward out of the water. The support component 40 is connected to the slope of the channel, and an elastic member 32 is provided on the support component 40, and the second end of the pull rope 30 is connected to the elastic member 32.
[0029] In this way, the supporting component 40 is arranged above the water surface, and the elastic member 32 acts as a tensioning force on the pull rope 30, that is, the distance between the height of the upper end of the pull rope 30 and the height of the floating block 20 is a fixed value. Therefore, whenever the floating block 20 moves upward, it can be reflected from the position of the top end of the pull rope 30. The depth of the silt can be determined by the change in the position of the top of the pull rope 30.
[0030] In an optional embodiment, the pull rope 30 includes a steel wire rope, and the diameter of the steel wire rope is formed by braiding multiple steel wires, and the diameter of the steel wire rope is less than 3 mm.
[0031] Furthermore, the floating block 20 can move relative to the limiting component 10 along its height direction, and the floating block 20 is constructed to be suspended above the silt under the action of the water flow. In this way, since the density of the floating block 20 is slightly greater than that of water and less than that of the silt, it will not sink into the silt. Furthermore, under the action of the water flow, the floating block 20 can remain floating above the silt and will not be submerged by the silt. Therefore, the floating block 20 can represent the height of the top of the silt at the current position.
[0032] In an alternative embodiment, in combination Figure 2 As shown, the buoy 20 is constructed as a disc-shaped structure 21, and the edge of the disc-shaped structure 21 has a smooth arc surface, which includes an upper arc surface and a lower arc surface, and the upper arc surface and the lower arc surface have the same shape and size. In this way, when water flows through the disc-shaped structure 21, since the water flow velocity on its upper surface and lower surface is the same, it can be placed at a predetermined height. If the lower surface of the disc-shaped structure 21 is attached to the silt or the bottom of the channel, the flow velocity on its upper surface is large, causing the disc-shaped structure 21 to float slightly. Therefore, the disc-shaped structure will not affect the deposition of silt.
[0033] Preferably, the buoy 20 is constructed as a circular, elliptical or regular polygonal disk-shaped structure 21 .
[0034] In an optional embodiment, the floating block 20 is a composite structure of plastic, wood and ceramics. By controlling the ratio of wood and ceramics, the density of the floating block 20 is slightly greater than that of water, and the density can be controlled to be about 1.2.
[0035] Furthermore, in order to ensure that the float 20 does not produce continuous rotation under the action of water flow, a pair of guide plates 22 are provided on the upper end surface of the float 20. The guide plates 22 are constructed to have a pair of guide slopes, including an upper guide slope and a lower guide slope, and the upper guide slope and the lower guide slope intersect at an acute angle.
[0036] Since a pair of guide vanes 22 are respectively disposed on both sides of the column 11 , the floating block 20 tends to make the guide vanes 22 face upstream under the action of the water flow, and will not rotate disorderly.
[0037] In a preferred embodiment, the guide piece 22 is located at the outer edge of the floating block 20 to avoid affecting the guide contour of the floating block 20 itself due to the setting of the guide piece 22 .
[0038] Combination Figure 3 As shown, the support component 40 includes a horizontal frame 41 and a vertical support plate 42 . The horizontal frame 41 is provided with a groove for the pull rope 30 to pass through, and the vertical support plate 42 is provided with a scale plate 43 on the side facing the pull rope 30 .
[0039] Among them, the cross frame 41 is set in a fork shape, extending inward from the slope to the top of the column 11. The height of the top end of the pull rope 30 changes with the height of the floating block 20. The top position of the pull rope 30 can be judged by the scale plate 43, which is used to characterize the depth of the bottom silt. When the depth is deeper, the pull rope 30 is closer to the top of the scale plate 43.
[0040] In an optional embodiment, the vertical support plate 42 is configured as an L-shaped plate, the elastic member 32 has a first end connected to the vertical support plate 42 , and a second end connected to the pull rope 30 via a column-type connection structure 31 .
[0041] The columnar connection structure 31 includes a first part and a second part, and the first part and the second part can rotate relative to each other.
[0042] In this way, when the float 20 rotates, the columnar connecting structure 31 can rotate due to stress, which can avoid the torsional stress of the pull rope 30 caused by the rotation of the float 20. The dividing line between the first part and the second part of the columnar connecting structure 31 can be used as a marking line to make the visual inspection result more accurate.
[0043] In combination with the above embodiments, the silt depth detection device proposed by the utility model represents the depth of the silt by setting a floating block that can be suspended on the surface of the silt in the waterway. The top of the floating block is extended above the water surface by a pull rope. The depth of the silt at the current position can be judged by observing the position of the upper end of the pull rope. The device can be arranged at a predetermined position of the waterway. The detection personnel can record the silt depth at the current position by regularly observing the position of the upper end of the pull rope on each device. The operation and recording are very simple and do not require professional skills.
[0044] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
