Description

Technical Field

[0001] This invention relates to the field of mapping silt thickness, and more specifically, to a mapping device for collecting underwater silt thickness. Background Technology

[0002] Wastewater treatment plant influent contains a lot of suspended solids, which will gradually settle to the bottom of the wastewater tanks as they enter the various treatment stages. Due to the short hydraulic retention time, the impact on the operation of the wastewater treatment plant is minimal in the short term. However, over time, the accumulated sediment will eventually form a sludge layer of a certain depth, reducing the effective volume of the tank. Tank dredging usually requires draining the water, which has a significant impact on production. Therefore, understanding the sludge deposition in the tank is the key to deciding whether to dredge.

[0003] Chinese patent number CN114909976A proposes a lifting mechanism that enables the device to be raised and lowered without the need for manual placement of the device at the bottom of the water for measurement. When the device enters the water, a gravity ball will keep the device in a vertical position with its center of gravity pointing downwards, preventing it from tilting and falling. After the gravity ball contacts the surface of the silt, a balancing mechanism automates the vertical adjustment of the device and the measurement, and a fixing mechanism fixes the vertical angle.

[0004] The existing iron concentrate powder dewatering device has the following shortcomings: 1. The existing underwater silt thickness measurement device is usually connected to the lifting equipment for use. After adjusting the measurement position, the device will shake to a certain extent, affecting the measurement effect. In addition, adjusting the position by lifting equipment lacks a certain degree of accuracy.

[0005] 2. The surveying device for measuring the thickness of underwater silt requires line laying during the measurement process, but it is easily affected by external factors. During the laying and reeling in, the suspension line is prone to knotting, which affects its subsequent use. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] according to Figure 1-5 The mapping device for collecting underwater silt thickness shown includes a mounting base 1 and fixing bolts 11 fixedly installed on the outer surface of the mounting base 1. A base 2 is installed on the top of the mounting base 1, and a mounting rod 3 is provided on the top of the base 2. A crossbeam 4 is fixedly installed on the top of the mounting rod 3. An adjustment component is provided inside the base 2 to adjust the direction of the crossbeam 4. A telescopic component is provided inside the crossbeam 4 to adjust the length of the crossbeam 4.

[0038] Furthermore, the adjustment assembly includes a turntable 21 located at the top center of the base 2, and the bottom end of the mounting rod 3 is fixedly connected to the turntable 21. A second gear 25 is located at the center of the bottom interior of the base 2, and the bottom end of the turntable 21 is fixedly connected to the second gear 25. A first gear 24 is located on one side of the second gear 25 at the bottom interior of the base 2, and the second gear 25 meshes with the first gear 24. The first gear 24 drives the second gear 25 on one side, and the second gear 25 drives the turntable 21 to rotate, thereby adjusting the position of the overall device. The first gear 24 is smaller than the second gear 25, reducing the rotation amplitude and increasing the accuracy of the adjustment.

[0039] Furthermore, a turntable 22 is provided on the top outer surface of the base 2 on one side of the turntable 21. The turntable 22 is fixedly connected to the first gear 24 through a connecting component at its bottom end. The connecting component includes a connecting pipe 26 located inside the base 2 below the turntable 22. The bottom end of the connecting pipe 26 is fixedly connected to the first gear 24. A limiting groove 27 is provided on the outer surface of the base 2 below the turntable 22. A limiting block 261 matching the limiting groove 27 is provided inside the limiting groove 27. The limiting block 261 is fixedly installed at the bottom end of the turntable 22. When the turntable 22 is pulled upward, the limiting block 261 with its bottom end disengages from the limiting groove of the base 2, releasing the limiting of the turntable 22. Then, the turntable 22 is rotated, which drives the first gear 24 below to rotate through the connecting pipe 26.

[0040] Furthermore, an inner rod 262 is provided inside the connecting tube 26, and the top end of the inner rod 262 is fixedly connected to the limiting block 261. A second baffle 263 is fixedly installed at the bottom end of the inner rod 262. A second return spring 264 is sleeved on the outer surface of the inner rod 262 above the second baffle 263. When the limiting block 261 moves upward, it will drive the inner rod 262 to slide upward. The first baffle 263 at the bottom end of the inner rod 262 will squeeze the first return spring 16.

[0041] Furthermore, the telescopic assembly includes a slide 41 disposed inside the crossbeam 4, and the slide 41 is slidably connected to the crossbeam 4. A first motor 43 is fixedly installed at the bottom end of the crossbeam 4. A slide groove 42 is formed on the outer surface of the bottom end of the slide 41. A third gear 44 is disposed inside the slide groove 42. The third gear 44 is engaged with a snap tooth on one side of the inner wall of the slide groove 42. The output shaft of the first motor 43 is fixedly connected to the third gear 44. When the first motor 43 at the bottom end of the crossbeam 4 is started, the third gear 44 inside the first motor 43 is driven to rotate, thereby driving the slide 41 to move, thereby adjusting the length of the crossbeam 4.

[0042] The specific implementation method is as follows: When adjusting the measurement position, the turntable 22 can be pulled upward first, and the bottom limiting block 261 disengages from the limiting groove of the base 2, releasing the limiting of the turntable 22. Then, the turntable 22 is rotated, which drives the first gear 24 below to rotate through the connecting pipe 26. The first gear 24 drives the second gear 25 on one side, and the second gear 25 drives the turntable 21 to rotate, thereby adjusting the position of the overall device. The first gear 24 is smaller than the second gear 25, which reduces the rotation amplitude and increases the accuracy of the adjustment. During the upward movement of the limiting block 261, the inner rod 262 will be driven. Sliding upwards, the first baffle 263 at the bottom of the inner rod 262 will press the first return spring 16. After adjustment, the turntable is released, and the first return spring 16 will drive the inner rod 262 to slide downwards, causing the limit block 261 to be inserted into the limit groove 27. The turntable 22 is then fixed in place. When the length of the crossbeam 4 needs to be adjusted, the first motor 43 at the bottom of the crossbeam 4 is started. The first motor 43 drives the internal third gear 44 to rotate. The third gear 44 engages with the locking teeth on one side of the slide groove 42, thereby moving the slide 41 and adjusting the length of the crossbeam 4, thus increasing the range that the surveying device can measure.

[0043] Example 2

[0044] according to Figure 6-7 The mapping device for collecting underwater silt thickness shown has an installation component between the mounting base 1 and the base 2, which connects the mounting base 1 and the base 2.

[0045] Furthermore, the mounting assembly includes a retainer 12 mounted on the top of the mounting base 1, and the bottom end of the base 2 is fitted onto the outer surface of the retainer 12. The retainer 12 has an inner groove around its perimeter, and a retaining post 14 is provided inside the inner groove. One end of the retaining post 14 is inclined. The outer surface of the base 2 has several retaining slots 23. When the mounting base 1 is connected to the base 2, one end of the retaining post 14 is inserted into the retaining slot 23, and the base 2 is fitted onto the retainer 12 at the top of the mounting base 1. During the downward pushing of the base 2, the retaining posts 14 around the perimeter will be pushed inward through the inclined end. During the inward pushing of the retaining post 14, the second return spring 264 inside will be squeezed. When the base 2 is fully fitted onto the retainer 12, one end of the retaining post 14 corresponds exactly to the retaining slot 23.

[0046] Furthermore, a guide rod 15 is fixedly installed at the other end of the locking post 14, a first baffle 18 is fixedly installed at one end of the guide rod 15, a retaining ring 17 is sleeved on the outer surface of one end of the guide rod 15, and a first return spring 16 is sleeved on the outer surface of the guide rod 15 on one side of the retaining ring 17. An inner disk 13 is provided inside the mounting base 1, and a magnetic block 131 is fixedly installed on the outer surface of the inner disk 13. When the inner disk 13 inside the mounting base 1 is rotated, the magnetic block 131 on the inner disk 13 aligns with one end of the second baffle 263. The second baffle 263 is attracted by the magnetic force of the magnetic block 131 and will drive the locking post 14 inward through the guide rod 15, so that one end of the locking post 14 disengages from the locking groove 23 of the base 2.

[0047] The specific implementation method is as follows: When installing the surveying device, first fix the mounting base 1 in the installation position using fixing bolts 11, and then put the base 2 onto the retaining seat 12 at the top of the mounting base 1. As the base 2 is pushed downward, the retaining posts 14 around it will be pushed inward through one end of the inclined surface. During the inward pushing of the retaining posts 14, they will compress the second return spring 264 inside. When the base 2 is completely fitted onto the retaining seat 12, one end of the retaining post 14 corresponds exactly to the retaining groove 23. At this time, the second return spring 264 will push the retaining post 14 inward. The device is installed by pushing it outward and inserting it into the slots 23 around the base 2. When disassembling the device, first remove the fixing bolts 11 to remove the mounting base 1. Then rotate the inner plate 13 inside the mounting base 1 so that the magnetic block 131 on the inner plate 13 corresponds to one end of the second baffle 263. The second baffle 263 is attracted by the magnetic force of the magnetic block 131 and will drive the locking post 14 inward through the guide rod 15, so that one end of the locking post 14 is disengaged from the slot 23 of the base 2, releasing the limit between the base 2 and the chuck 13. Then the base 2 can be removed, which is more convenient.

[0048] Example 3

[0049] according to Figure 8-11 The surveying device shown is used to collect the thickness of underwater silt. One end of the cross frame 4 is equipped with a plumb bob 48, and the top of the plumb bob 48 is fixedly connected to a suspension rope 45. The top of the cross frame 4 is equipped with a retraction mechanism, which is used to retract and extend the suspension rope 45.

[0050] Furthermore, the take-up and release assembly includes a take-up and release frame 5, with mounting brackets 51 fixedly installed at both ends of the take-up and release frame 5. A take-up shaft 57 is provided at the center of the inside of the take-up and release frame 5. A second motor 55 is fixedly installed on one outer surface of the mounting bracket 51. The output shaft of the second motor 55 is fixedly connected to the take-up shaft 57. A guide wheel 46 is fixedly installed on one outer surface of the slide 41. The suspension rope 45 is wound on the outer surface of the take-up shaft 57. One end of the suspension rope 45 passes through the inside of the take-up and release frame 5, passes around the guide wheel 46, and is fixedly connected to the top of the plumb bob 48. A sleeve 47 is fixedly installed at the bottom end of the slide 41, and the sleeve 47 is fitted on the outer surface of the suspension rope 45. A display 52 is fixedly installed on the other outer surface of the mounting bracket 51. The second motor 55 drives the take-up shaft 57 to rotate, releasing the suspension rope 45. The suspension rope 45 moves along the guide wheel 46, lowering the plumb bob 48 at the bottom until the plumb bob 48 is inserted into the bottom of the silt.

[0051] Furthermore, a slot 53 is provided on one outer surface of the take-up and release frame 5, and a cable outlet tube 54 is provided inside the slot 53. The suspension rope 45 passes through the inside of the cable outlet tube 54. A screw 58 is provided inside the take-up and release frame 5 near the slot 53. A slider 541 is fixedly installed at the top of the cable outlet tube 54, and the slider 541 is sleeved on the outer surface of the screw 58. The slider 541 is threadedly connected to the screw 58. A third motor 56 is fixedly installed on one outer surface of the mounting frame 51, located on the side of the second motor 55. One end of the output shaft of the third motor 56 is fixedly connected to one end of the screw 58. The third motor 56 on one side of the mounting frame 51 will start, driving the internal screw 58 to rotate. The screw 58 is threadedly connected to the slider 541. The slider 541 drives the cable outlet tube 54 to slide along the slot 53, thereby driving the suspension rope 45 to be evenly wound on the surface of the take-up shaft 57.

[0052] The specific implementation method is as follows: During measurement, the plumb bob 48 is moved to the measurement position, and then the second motor 55 on one side of the mounting bracket 51 is started. The second motor 55 drives the take-up shaft 57 to rotate, releasing the suspension rope 45. The suspension rope 45 moves along the guide wheel 46, lowering the bottom plumb bob 48 until it is inserted into the bottom of the silt. When the suspension rope 45 is released, it will pass through the exit tube 54. A speed sensor is installed inside the exit tube 54. The length of the suspension rope 45 released is calculated by the release speed and release time, thereby calculating the thickness of the silt. The calculated data is displayed on the monitor 52. After the measurement is completed, the second motor 55 retracts the suspension rope 45. During the retraction of the suspension rope 45, the surface silt is scraped off through the sleeve 47. At the same time, the third motor 56 on one side of the mounting bracket 51 is started, driving the internal screw 58 to rotate. The screw 58 is threadedly connected to the slider 541. The slider 541 drives the cable outlet tube 54 to slide along the slot 53, thereby driving the suspension rope 45 to be evenly wound on the surface of the take-up shaft 57, avoiding the suspension rope 45 from getting tangled, and facilitating subsequent use.

[0053] Working principle of this invention:

[0054] Refer to the instruction manual appendix Figure 1-5 When adjusting the measurement position, the turntable 22 is rotated, which drives the first gear 24 below to rotate through the connecting pipe 26. The first gear 24 drives the second gear 25 on one side, and the second gear 25 drives the turntable 21 to rotate, thereby adjusting the position of the overall device. When it is necessary to adjust the length of the crossbeam 4, the first motor 43 at the bottom of the crossbeam 4 is started, which drives the internal third gear 44 to rotate. The third gear 44 engages with the locking teeth on one side of the slide 42, thereby driving the slide 41 to move, thereby adjusting the length of the crossbeam 4 and increasing the measurement range that the surveying device can measure.

[0055] Refer to the instruction manual appendix Figure 6-7 When installing the surveying device, first fix the mounting base 1 in the installation position with fixing bolts 11, and then put the base 2 on the card seat 12 at the top of the mounting base 1. As the base 2 is pushed down, the four card posts 14 will be pushed inward by one end of the inclined surface. When the base 2 is completely put on the card seat 12, one end of the card post 14 corresponds to the card slot 23. At this time, the second return spring 264 will push the card post 14 outward and insert it into the card slot 23 around the base 2, thus completing the installation of the device. When disassembling the device, rotate the inner plate 13 inside the mounting base 1 so that the magnetic block 131 on the inner plate 13 corresponds to one end of the second baffle 263, release the limit between the base 2 and the card plate 13, and then remove the base 2, which is more convenient.

[0056] Refer to the instruction manual appendix Figure 8-11During measurement, the plumb bob 48 is moved to the measurement position, and then the second motor 55 on one side of the mounting bracket 51 is started. The second motor 55 drives the take-up shaft 57 to rotate, releasing the suspension rope 45. The suspension rope 45 moves along the guide wheel 46, lowering the bottom plumb bob 48 until it is inserted into the bottom of the silt. When the suspension rope 45 is released, it will pass through the outlet tube 54. The outlet tube 54 is equipped with a speed sensor. The length of the suspension rope 45 released is calculated by the release speed and release time, thereby calculating the thickness of the silt. The calculated data is displayed on the display 52. ​​After the measurement is completed, the second motor 55 is used to retrieve the suspension rope 45. During the retrieval of the suspension rope 45, the surface silt is scraped off through the sleeve 47.
