Description

Technical Field

[0001] This application relates to the field of waterway inspection equipment, and in particular to a device for measuring the depth of a riverbed. Background Technology

[0002] As a traditional device for measuring the depth of riverbeds, the sounding hammer is still widely used for small-scale depth measurement in shallow water areas with a depth of 30-60 meters due to its low cost and ease of use.

[0003] During the use of a sounding hammer, the sounding hammer needs to be placed vertically into the water and then sink naturally to the bottom. Common sounding hammers are usually used by the tester to measure the depth by hand. During the detection process, because it is handheld, the rope may deviate during the lowering of the sounding hammer, which will reduce the accuracy of the final measurement result. Summary of the Invention

[0004] To address the issue of low accuracy caused by rope deviation during traditional handheld sounding hammer measurements of riverbed depth, this application provides a riverbed depth measurement device.

[0005] The riverbed depth measuring device provided in this application adopts the following technical solution:

[0006] A riverbed depth measuring device includes a mounting frame, a sounding hammer, a pull rope, and a take-up reel. The pull rope is wound around the take-up reel, and the sounding hammer is connected to one end of the pull rope. The take-up reel is rotatably mounted on the mounting frame. A first support rod is provided on the mounting frame, and the axis of the take-up reel is perpendicular to the axis of the first support rod. A second support rod is slidably mounted on the first support rod, and the axis of the second support rod is perpendicular to the axis of the first support rod. A third support rod is slidably mounted on the second support rod, and the third support rod is parallel to the first support rod. A first fixing member is provided on the first support rod to fix the second support rod, and a second fixing member is provided on the second support rod to fix the third support rod. A horizontal mechanism is also provided on the mounting frame to keep the axis of the take-up reel horizontal.

[0007] The above technical solution fixes the mounting frame and take-up reel to the hull of the measuring vessel through the cooperation of the first support rod, the second support rod and the third support rod. This makes it less likely for the rope to deviate during the sinking of the sounding hammer, and the measurement results of the sounding hammer are more accurate.

[0008] Optionally, the first fixing member includes a first slider slidably mounted on the first support rod, and a first fixing bolt is threaded onto the first slider. After tightening the first fixing bolt, one end of the first fixing bolt abuts against the first support rod. The second support rod is mounted on the first slider. The second fixing member includes a second slider slidably mounted on the second support rod, and a second fixing bolt is threaded onto the second slider. After tightening the second fixing bolt, one end of the second fixing bolt passes through the second slider and abuts against the second support rod. The third support rod is mounted on the second slider.

[0009] Optionally, the first slider has a first connecting hole, one end of the second support rod slides through the first connecting hole and slides to connect with the first slider, a tension nut is threaded on the end of the second support rod that passes through the first connecting hole, the second slider has a second connecting hole, one end of the third support rod slides through the second connecting hole, and a third fixing bolt is also threaded on the second slider. After tightening the third fixing bolt, one end of the third fixing bolt passes through the second slider and abuts against the side wall of the third support rod.

[0010] Optionally, the cross-sections of the first support rod, the second support rod, and the third support rod are all circular, and a sliding surface is provided on the side wall of each of the first support rod, the second support rod, and the third support rod. The sliding surface is rectangular and is respectively arranged along the axial direction of the first support rod, the second support rod, and the third support rod. After the first fixing bolt, the second fixing bolt, and the third fixing bolt are tightened, they all abut against the corresponding sliding surface.

[0011] While limiting the rotation of the first support rod, the second support rod, and the third support rod, the sliding surface also increases the contact area of ​​the first and second fixing bolts after tightening, resulting in a better fixing effect of the first and second fixing bolts.

[0012] Optionally, the mounting bracket is slidably sleeved on the first support rod. The horizontal mechanism includes a mounting plate threaded onto the first support rod, the surface of which is perpendicular to the axis of the first support rod. Two rotating shafts are provided on the mounting plate, the axes of which are parallel to the axis of the first support rod. Two horizontal rods are rotatably mounted on the rotating shafts. A fixing nut is threaded onto one end of each rotating shaft. After tightening the fixing nut, the fixing nut pushes the horizontal rod against the mounting plate. The length direction of the horizontal rod is parallel to the surface of the mounting plate. An adjusting bolt is threaded onto the end of the horizontal rod away from the mounting plate, the axis of which is parallel to the axis of the first support rod. A locking nut is threaded onto the end of the first support rod that passes through the mounting bracket, and the locking nut abuts against the mounting bracket. A level is also provided on the mounting bracket.

[0013] Optionally, the first support rod is defined as being placed vertically, the adjusting bolt is also vertical, and the lower end of the adjusting bolt is tapered.

[0014] Optionally, an adjusting wheel is provided on the mounting frame, and an adjusting block is slidably mounted on the mounting frame on both sides of the adjusting wheel. The sliding direction of the adjusting block is parallel to the axis of the first support rod. The adjusting wheel is rotatably mounted on the two adjusting blocks. The first support rod is defined as being placed vertically. A detection spring is provided on the bottom wall of the adjusting block. A pressure switch is installed on the frame. The upper end of the detection spring abuts against the bottom wall of the adjusting block, and the lower end of the detection spring abuts against the pressure switch. The pull rope starts from the take-up reel, passes around the adjusting wheel, and extends vertically downward. The height of the upper side of the adjusting wheel is higher than the height of the upper side of the take-up reel. The elastic force generated by the compression of the detection spring is less than the tension of the sounding hammer and the pull rope on the adjusting wheel. A reduction motor is also installed on the frame. The reduction motor is used to drive the take-up reel to rotate. The reduction motor is electrically connected to the pressure switch.

[0015] Optionally, the frame has two slide grooves with a T-shaped cross-section. The two adjusting blocks are slidably installed in the T-shaped horizontal sections of the two slide grooves. The two ends of the mounting shaft of the adjusting wheel pass through the T-shaped vertical sections of the two slide grooves and are rotatably connected to the adjusting blocks. The detection spring and the pressure switch are both installed in the T-shaped horizontal sections of the slide grooves.

[0016] Optionally, the first support rod is defined as vertical, a first pressure block is slidably sleeved on the lower end of the first support rod, and a second pressure block is slidably sleeved on the lower end of the third support rod. Both the first pressure block and the third pressure block are made of materials with a high coefficient of friction.

[0017] In summary, this application, through the cooperation of the first, second, and third support rods, fixes the mounting frame and the take-up reel to the hull side. When the vessel stops, the mounting frame and take-up reel fixed to the hull side are also stationary, making it less likely for the pull rope to deviate during the sounding hammer's sinking process. Simultaneously, when the sounding hammer touches the bottom, the pressure of the sounding hammer and pull rope on the detection spring decreases, causing the detection spring to rebound. The pressure switch detects the reduced pressure and stops the reduction motor, which in turn stops the rotation of the take-up reel. This ensures more timely cessation of the pull rope release, making the amount of pull rope released closer to the actual river depth and resulting in more accurate detection results.

The second slider 71 is fixed onto the second support rod 4 by tightening the second fixing bolt 72. Then, the mounting frame 1 is erected on the hull by the first support rod 3, the second support rod 4, and the third support rod 5. After tightening the tension nut 41, the first support rod 3 and the third support rod 5 are clamped onto the hull by the first pressure block 32 and the second pressure block 51.

[0030] Reference Figure 1 and Figure 2 The horizontal mechanism 8 also includes two horizontal rods 83. A rotating shaft 82 is integrally mounted on each side of the mounting plate 81 located on the first support rod 3. One end of each horizontal rod 83 is mounted on one of the two rotating shafts 82. A fixing nut 84 is threaded onto each of the two rotating shafts 82. Tightening the fixing nut 84 pushes the horizontal rod 83 against the mounting plate 81. An adjusting wheel 13 bolt is threaded onto the end of the horizontal rod 83 facing away from the mounting plate 81. The adjusting bolt 85 is parallel to the first support rod 3, and its lower end is tapered.

[0031] Reference Figure 1 and Figure 2A level 19 is fixedly installed on the mounting frame 1. After the mounting frame 1 is clamped and fixed on the edge of the boat, the level rod 83 is rotated and adjusted until the adjusting bolt 85 is above the edge of the boat. Then, the adjusting bolt 85 is rotated until the lower end of the adjusting bolt 85 is pressed against the top wall of the edge of the boat. Then, by observing the level 19, the two adjusting bolts 85 are turned to adjust the mounting frame 1 to be horizontal and the first support rod 3 is adjusted to be vertical.

[0032] Reference Figure 1 and Figure 2 A take-up reel 12 and an adjusting reel 13 are rotatably mounted on the mounting frame 1. The axes of both the take-up reel 12 and the adjusting reel 13 are perpendicular to the axis of the first support rod 3, and the axes of both the take-up reel 12 and the adjusting reel 13 are perpendicular to the sliding surface 9 of the first support rod 3. The take-up reel 12 and the adjusting reel 13 are on the same straight line in the horizontal direction, and the upper side of the take-up reel 12 is lower than the upper side of the adjusting reel 13 in the vertical direction. A pull rope 11 is wound around the take-up reel 12. One end of the pull rope 11 extends from the take-up reel 12, passes over the adjusting reel 13, and then extends vertically downward. A sounding plumb bob 2 is fixedly connected to the lower end of the vertical section of the pull rope 11.

[0033] Reference Figure 1 and Figure 3 A groove 18 is provided on the mounting bracket 1 at both ends of the axis of the adjusting wheel 13. The cross-section of the groove 18 is T-shaped, and the length of the groove 18 is vertical. An adjusting block 14 is slidably installed in the horizontal section of the T-shape of the groove 18. A pressure switch 16 is fixedly installed on the bottom wall of the horizontal section of the T-shape of the groove 18. A detection spring 15 is provided between the pressure switch 16 and the adjusting block 14, with its two ends abutting against the top wall of the pressure switch 16 and the bottom wall of the adjusting block 14, respectively. The two ends of the mounting shaft of the adjusting wheel 13 pass through the two grooves 18 and are rotatably connected to the two adjusting blocks 14. The elastic force of the detection spring 15 is less than the weight of the sounding hammer 2.

[0034] Reference Figure 1 and Figure 3A geared motor 17 is fixedly mounted on the mounting frame 1. The output shaft of the geared motor 17 is coaxially connected to the take-up reel 12, driving the take-up reel 12 to rotate. Simultaneously, the geared motor 17 is electrically connected to the pressure switch 16. The geared motor 17 drives the take-up reel 12 to release the line. When the sounding hammer 2 is sinking, its weight pulls the adjusting wheel 13 downwards, causing the detection spring 15 to press against the pressure switch 16. The pressure switch 16 closes, and the geared motor 17 continues to operate. When the sounding hammer 2 touches the bottom, the detection spring 15 rebounds, and the pressure switch 16 loses sufficient pressure, causing it to disconnect. The geared motor 17 stops, and the take-up reel 12 stops rotating, stopping the release of line. The length of the released rope 11 at this point is the depth of the riverbed. Because monitoring is done through the detection spring 15, compared to manual observation and then stopping the release, the coordinated action of the pressure switch 16 and the geared motor 17 allows for more timely stopping of the release, resulting in higher overall testing accuracy.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
