Description

Technical Field

[0001] The invention relates to the technical field of sludge thickness detection sensors, and in particular to a sludge thickness detection device and a detection method for water conservancy detection. Background Art

[0002] The silt thickness detection of water conservancy projects is extremely important. It can accurately evaluate the accumulation of water sediments and provide key decision-making basis and direction guidance for subsequent dredging operations, ecological environment governance and water quality improvement. In the case of shallow waters, the detection rod is a commonly used silt thickness detection tool. The specific operation process is as follows: The detection personnel slowly insert the detection rod vertically into the silt, and the silt will leave clear adhesion marks on the rod body; then carefully pull the detection rod out of the silt, carefully observe the retention position of the silt on the detection rod, and use a tape measure to accurately measure the length of this position from the bottom of the rod. The data obtained is the thickness of the silt.

[0003] After searching, the Chinese patent with the authorization announcement number CN221445043U discloses a silt thickness detection device for water conservancy detection, including a detection box and a fixed bottom plate, a detection device is arranged inside the detection box, and a cleaning device is arranged on the left side of the bottom of the detection box. The silt thickness detection device for water conservancy detection, the connecting sleeve rod moves downward to drive the detection rod and the bottom contact plate at the bottom thereof to move downward until the pressure sensor contacts the river bottom, thereby completing the silt thickness detection, and when the bottom contact plate contacts the stone during the detection process, the irregular stone cannot synchronously trigger the five pressure sensors, thereby avoiding the occurrence of misjudgment of the silt thickness, when the detection is completed, the driving detection unit rises, the electromagnetic coil is energized, thereby generating a repulsive force, pushing the permanent magnet block to slide outward inside the limit block, and then pushing the slide bar to slide outward along the through hole, so that the cleaning scraper is close to the outer surface of the detection rod, so that the silt on the outer surface of the detection rod is scraped off when the detection rod rises.

[0004] In the above patent, the detection device needs to be installed on the shore or on a ship through a fixed base plate. When installed on the shore, the detection device can only detect the thickness of the silt on the shore, and the detection range is limited. When the detection device is installed on a ship, if the hull is in a shaking state, it cannot be guaranteed that the detection rod is vertically inserted into the silt, and the detection result will be erroneous. The use of the detection device has great limitations and the detection accuracy needs to be improved. Therefore, this application provides a silt thickness detection device and detection method for water conservancy detection to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a sludge thickness detection device and a detection method for water conservancy detection to solve the problem that the use of the detection device is relatively limited and the detection accuracy needs to be improved.

[0010] Preferably, the round tube is an acrylic tube, and the reference component includes a connecting piece, which is rotatably connected to the bottom of the handle, and a cone block is fixed to the bottom of the connecting piece.

[0015] A method for detecting sludge thickness for water conservancy detection, using the above device, comprises the following steps: S1: Before conducting sludge detection, check whether the outer tube and the detection rod are in a vertical state by using the reference assembly; S2: During the sludge detection, the detection rod is driven by the motor to be inserted downward into the sludge, and the distance the detection rod moves downward is measured by the distance sensor, so as to determine the thickness of the sludge; S3: When there are waves, the water-repelling component is used to reduce the impact of the waves on the floating plate with holes; S4: After the sludge detection is completed, remove the device from the water.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting an outer tube, a detection rod, a pressure sensor, a floating plate with holes and a reference component, when the sludge thickness is detected, the outer tube is supported on the sludge, and the verticality of the outer tube and the detection rod is improved by the reference component, thereby improving the detection accuracy. The outer tube can be supported on the water surface by the floating plate with holes, and the sludge thickness at different positions can be detected, and the detection limitations are smaller.

[0017] By setting a laser emitter, a positioning plate and a positioning ring, when the laser emitted by the laser emitter is located in the positioning ring, the outer tube and the detection rod are in a vertical state, and when the laser emitted by the laser emitter is located outside the positioning ring, the outer tube and the detection rod are in a non-vertical state. Detection is performed by using the laser emitted by the laser emitter, which makes detection more convenient.

[0018] By setting up the connecting components, when there is wind during the detection process, the wind will generate waves on the water surface. After the waves hit the floating plate with holes, they are buffered by the connecting components, reducing the impact on the outer tube and the detection rod, and further improving the detection accuracy of the silt thickness.

[0019] By setting up the water-displacing assembly and the second pressure sensor, when waves are generated, the waves will drive the circular plate and the paddle plate to rotate. During the rotation, the paddle plate can drive the floating plate with holes to generate a force facing the wave direction, thereby reducing the shaking of the floating plate with holes, thereby improving the detection accuracy. At the same time, the bearing capacity of the floating plate with holes is detected by the second pressure sensor. The second pressure sensor controls the motor to drive the circular plate and the paddle plate to rotate, thereby increasing the force of the floating plate facing the wave direction. The detection accuracy is further improved through the precise control of the second pressure sensor.

[0020] By providing the curved groove and the elastic strip, after the paddle contacts the water surface, the elastic strip is sunken in the direction of the curved groove, thereby increasing the contact area between the paddle and the water and increasing the force generated during waves; when the paddle leaves the water, the elastic strip rebounds, and the water in the curved groove is ejected after the elastic strip rebounds, thereby preventing the accumulated water in the curved groove from affecting the rotation of the paddle.

[0021] By setting up a support component, the support component can increase the contact area between the outer tube and the silt, preventing the outer tube from sinking into the silt, and using a support net for support. When the outer tube rises or falls, water can flow through the support net, reducing the components of the water flow. The circular tube is more stable during the rising or falling process. Secondly, the support net can rotate on the outer tube, so that the support net can adapt to more complex terrain. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figure 7 and Figure 8 As shown, in this embodiment, the water-displacing assembly 23 includes a motor 24 embedded in the side of the perforated floating plate 13, a circular plate 25 is fixed to the output end of the motor 24, a plurality of paddle plates 26 are fixed to the end of the circular plate 25, a pressure sensor 235 is fixed to the end of the top sleeve 20, the pressure sensor 235 is against the positioning hole 22, the rotation speed of the motor 24 is controlled by the pressure value detected by the pressure sensor 235, the pressure sensor 235 is electrically connected to the display 8, the motor 24 is electrically connected to the display 8, the motor 24 can drive the circular plate 25 to rotate, the circular plate 25 drives the paddle plates 26 to rotate, and can drive the perforated floating plate 13 to face the waves, reduce the impact of the waves on the perforated floating plate 13, thereby avoiding affecting the verticality of the outer tube 1, thereby improving the detection accuracy.

[0036] like Figure 8 As shown, in this embodiment, a curved groove 27 is opened on the side of the paddle 26 that rotates into the water, and an elastic strip 28 is fixed to the inner wall of the curved groove 27.

[0037] like Figure 6 As shown, in this embodiment, a support assembly 36 is provided on the surface of the outer tube 1, and the support assembly 36 includes a circular sleeve 37, which is fixed to the surface of the outer tube 1 by bolts, and a ball ring 2 38 is fixedly sleeved on the surface of the circular sleeve 37, and a ring sleeve 39 is movably sleeved on the surface of the ball ring 2 38, and a support net 40 is fixedly sleeved on the surface of the ring sleeve 39, and the ring sleeve 39 drives the support net 40 to rotate on the ball ring 2 38, and the center point of the rotation is at the bottom end position of the detection rod 2. After the support net 40 is supported on the silt, with the support net 40 as the reference plane, the distance that the detection rod 2 moves downward is the thickness of the silt.

[0038] A method for detecting sludge thickness for water conservancy detection, using the above device, comprises the following steps: S1: Before the sludge detection, the outer tube 1 and the detection rod 2 are checked to see if they are in a vertical state by using the reference assembly; S2: During the sludge detection, the motor 3 drives the detection rod 2 to be inserted downward into the sludge, and the distance sensor 41 measures the distance the detection rod 2 moves downward, thereby determining the thickness of the sludge; S3: When there are waves, the water-repelling component 23 is used to reduce the impact of the waves on the perforated floating plate 13; S4: After the sludge detection is completed, remove the device from the water.

[0039] Working principle: When conducting sludge detection, put the outer tube 1 and the floating plate with holes 13 into the water, and the outer tube 1 drives the supporting assembly 36 to fit on the top of the sludge. At this time, observe whether the laser emitted by the laser emitter 31 is within the positioning circle 34. If the laser beam is within the positioning circle 34, it means that the outer tube 1 and the detection rod 2 are in a vertical state. When the laser beam is outside the positioning circle 34, the outer tube 1 and the detection rod 2 are in a non-vertical state. When the outer tube 1 and the detection rod 2 are in a non-vertical state, the outer tube 1 is rotated by the handle 12, and the floating plate 13 with holes is rotated on the outer tube 1 through the connecting assembly 15 until the outer tube 1 is moved to a vertical state; At the same time, after the pressure sensor 5 contacts the silt and detects the reaction force of the silt, the pressure sensor 5 sends a signal to the information processing unit in the display 8. The information processing unit controls the motor 3 to start through the control unit, and the motor 3 will drive the screw 4 to rotate, and the screw 4 will drive the detection rod 2 to move downward. After the detection rod 2 is inserted into the silt, the pressure detected by the pressure sensor 5 increases slowly and is displayed on the display 8. The detection rod 2 is moving downward, and the distance sensor 41 measures the distance the detection rod 2 moves downward. This distance is the thickness of the silt. When the pressure sensor 5 passes through the silt and rests on the bottom of the riverbed, the reaction force provided by the bottom of the riverbed is greater, and the vertical detected by the pressure sensor 5 will fluctuate significantly. At this time, the motor 3 stops rotating, and the thickness of the silt is displayed on the display 8. When there is wind during the detection, the wind energy will generate waves on the water surface, and the waves will drive the paddle 26 to rotate. The rotation of the paddle 26 will generate a force in the direction of the waves. The paddle 26 will drive the perforated floating plate 13 to face the waves through the circular plate 25 and the motor 24, thereby reducing the impact of the waves on the perforated floating plate 13. Secondly, the impact force of the waves on the perforated floating plate 13 can be detected by the pressure sensor 235. After the pressure sensor 235 detects the pressure, the pressure sensor 235 sends a signal to the information processing unit in the display 8. The information processing unit controls the motor 24 to rotate through the control unit, and the motor 24 drives the circular plate 25 to rotate, and the circular plate 25 drives the paddle 26 to rotate. Actively driving the paddle 26 to rotate can further drive the perforated floating plate 13 to face the waves, thereby further reducing the impact of the waves on the perforated floating plate 13, thereby improving the detection accuracy.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
