Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a device for detecting the thickness of river silt. Background Technology

[0002] River siltation refers to the phenomenon where sediment is deposited on the riverbed, causing the riverbed to rise continuously. The causes of siltation include sediment exchange due to river dynamics and the impact of human activities. Many rivers have become increasingly silted up year by year due to a lack of dredging and maintenance. When dredging silt, it is necessary to accurately calculate the exact amount of silt at the bottom of the channel beforehand to effectively allocate manpower for silt removal and to conveniently select a location to hold the removed silt.

[0003] Currently, when measuring silt, operators typically use a pole inserted vertically into the bottom of the riverbed. Because silt is soft, the pole can be easily inserted. When the pole can no longer be inserted, it indicates that the bottom of the pole has reached the bottom of the riverbed. The pole is then pulled out, and the silt mark on the pole indicates the thickness of the silt. However, for rivers with flowing water, the water washes away the silt when the pole is pulled out, affecting the measurement results. Also, the fixed length of the pole may not reach the bottom of the silt during measurement. Therefore, a riverbed silt thickness detection device is needed to solve these problems.

Detailed Implementation

[0022] Example 1

[0023] like Figures 1 to 10As shown, this utility model discloses a device for detecting the thickness of river silt. The technical solution includes a floating platform 1, with a detection port 101 at the center of the upper surface of the floating platform 1. A positioning tube 2, coaxial with the detection port 101, is arranged above the detection port 101. A protrusion 201 is arranged on the inner side of the positioning tube 2. A threaded post 102 is arranged on the upper surface of the floating platform 1. A fixing ring 203 is fixedly sleeved on the lower end of the positioning tube 2. The fixing ring 203 is sleeved on the threaded post 102 and passes through a positioning tube 102 located above it. The fixed nut 204 is used for fixing. The detachable positioning tube 2 makes it easy to replace the floating platform 1 of different sizes for use. The positioning tube 2 has a probe 3 that slides up and down inside. The top of the probe 3 has a handle 301. The outer side of the probe 3 has a groove 302 that cooperates with the protrusion 201. The outer side of the probe 3 has a scale line. The lower end of the probe 3 has a contact plate 5 with a water passage groove. The contact plate 5 is locked on the lower surface of the floating platform 1.The probe tube 3 has a probe rod 4 that slides up and down inside. The probe rod 4 includes an insertion rod 41 and an extension rod 42. The top of the insertion rod 41 has a threaded groove, and the lower end of the extension tube 42 is connected to the threaded groove via a threaded protrusion. Scale lines are drawn on the outer surfaces of the insertion rod 41 and the extension rod 42. The bottom of the insertion rod 41 has a cone head 411, and the lower end of the extension rod 42 has a limit spring button 421 that can be locked onto the upper end of the probe tube 3. A fixing screw 202 is threaded onto the front side of the positioning tube 2. The lower ends of the probe tube 3 and the insertion rod 41 have corresponding first positioning holes 304 and second positioning holes 412, respectively. The inner end of the fixing screw 202 passes through the first positioning hole 304 and extends into the second positioning hole 412. Through the fixing screw 202, the first positioning hole 304, and the second positioning hole 412, the probe tube 3 and probe rod 4 can be fixed when not in use. The lower end of the positioning tube 2 is provided with an external threaded tube 303. The contact plate 5 is sleeved on the external threaded tube 303 and fixed to it by the mounting nut 501 located below it. The removable contact plate 5 allows the probe tube 3 to be easily pulled out of the positioning tube 2, facilitating storage and transportation. The top of the extension rod 42 has the same threaded groove as the top of the insertion rod 41. The probe 3 has threaded protrusions that can connect multiple extension rods 42, thereby increasing the length of the insertion rod 41 as needed. A limiting slide is provided on the inner side of the lower end of the probe 3, located below the first positioning hole 304. A limiting slider 413 is provided on the lower end of the insertion rod 41, located below the second positioning hole 412. The limiting slider 413 cooperates with the limiting slide of the probe 3. Through the limiting slide and the limiting slider 413 of the probe 3, the first positioning hole 304 and the second positioning hole 412 can be easily aligned. The probe 3 and the probe rod 4 can be brought to the river surface for operation via the floating platform 1. The probe 3 is inserted into the river water to measure the distance from the river surface to the silt surface. Contact plate 5 contacts the silt surface to prevent probe 3 from descending further into the silt. The cone 411 at the lower end of insertion rod 41 facilitates insertion of the rod 41 into the silt. Extension rod 42 extends the insertion rod 41. After the cone 411 reaches the bottom, the silt thickness is calculated by subtracting the insertion depth of probe 3 from the depth of extension rod 42 and insertion rod 41. The silt thickness can be determined without removing probe 4. Limit spring button 421 prevents probe 4 from falling into the river water when not being gripped. Simultaneously, the limit spring button 421 increases the damping of probe 4 and probe 3 as it moves within probe 3, thus facilitating control of probe 4.

[0024] The working principle of this utility model is as follows: The floating platform 1 is brought to a suitable position on the river surface. The probe 3 is grasped and the fixing screw 202 is unscrewed. Then, the handle 301 is grasped and the contact plate 5 is pushed down into the river water. The contact plate 5 gradually descends and, after contacting the surface of the silt, the pressure changes and is transmitted to the handle 301. At this time, the probe 3 reads the value of the side scale line. The extension rod 42 is grasped and the limit spring button 421 is pressed down. At the same time, the extension rod 42 is pressed down, and the limit spring button 421 is retracted into the positioning tube 2. The cone 411 descends and pierces the water surface, and then pierces into the silt. When the length is insufficient, the next section of the extension rod 42 is connected. After reaching the bottom, the value that is level with the top of the probe 3 is read. This value is subtracted from the length of the probe 3 exposed on the floating platform 1, and then the previous value of the probe 3 is subtracted to obtain the silt thickness.
