Description

Technical Field

[0001] The invention relates to the technical field of engineering measurement, and in particular to a depth sounding device suitable for measuring the depth of water area with high precision. Background Art

[0002] Water depth measurement is a common measurement method in ports, waterways and hydraulic projects. By accurately measuring the underwater terrain, it can provide certain guidance for construction and can also verify the accuracy of construction results. Accurate measurement of water depth is of great significance in the entire construction process.

[0003] Depth measurement often requires renting ships, and most of them are ships with strings. Due to the instability of the ship type, there is no stable place on the ship to fix the depth sounding instrument. The depth sounding equipment itself has a certain weight. In addition, during the depth measurement process, the ship speed, water and water resistance are very large. There are certain errors in the measurement of the depth sounding rod. The measurement environment in different waters also varies. When there are aquatic plants, it will affect the measurement accuracy of the sounding rod. In traditional depth measurement, the depth sounding rod is often fixed to the ship by binding it with a rope. The verticality of the depth sounding rod and the water surface will affect the overall measurement accuracy. At the same time, it is subject to resistance from all aspects during the operation. The depth sounding rod will shake and slide and is unstable, affecting the safety of the operation and the accuracy of the measurement.

DETAILED DESCRIPTION

[0043] like Figure 1-8 A depth sounding device suitable for high-precision measurement of water depth includes a guiding unit 2 and a detecting unit 3 arranged on a boat 1. The guiding unit 2 and the detecting unit 3 are connected to the boat 1 through a fixing unit 4, respectively. A drone 7 is arranged on the upper side of the guiding unit 2. The guiding unit 2 and the drone 7 cooperate to ensure that the walking direction of the boat 1 is accurate. A depth sounding rod 8 is detachably arranged on the detecting unit 3. The depth sounding rod 8 extends into the water. A mowing unit 5 is arranged on one side of the detecting unit 3. The mowing unit 5 is used to ensure that the measuring environment of the depth sounding rod 8 is stable. Due to the differences in different waters and water quality environments, in the process of measuring the depth of the water area, in order to ensure the measurement effect, the mowing unit 5 explores the way in front and removes the water plants or debris that may block the depth measuring rod 8 to ensure the accuracy of the measurement. Since the ship is sailing in the water area, it is impossible to ensure that the sailing direction is completely consistent with the set direction. The drone 7 is used for guidance. First, a GPS cloud map is drawn in the drone 7 according to the established path. The drone 7 completes the initial path detection of the water area, and compares it with the theoretical set path as a basis, and then corrects it. During the movement of the boat 1, the vertical rod 701 under the drone 7 cooperates with the guiding unit 2 to guide the unit 2 to ensure that the deviation is within the allowable range. When the deviation is too large, correction is made, and the deviation correction is performed in real time throughout the whole process, which is conducive to the accuracy of the depth measurement result. The detection unit 3 ensures the high vertical accuracy of the installation of the depth measuring rod 8. The verticality of the depth measuring rod 8 and the water surface affects the overall measurement accuracy. In this way, the overall measurement efficiency is high and the measurement accuracy is high, which is convenient for the later engineering construction. When in use, for the convenience of the operator to check, it is preferred to set the guide unit 2 and the detection unit 3 on the same side of the boat 1, and then place a water tank 6 on the side of the boat 1 away from the guide unit 2. The water in the water tank 6 is directly taken from the water area, and the water tank 6 is used to achieve the effect of force balance on both sides of the boat 1, thereby avoiding the uneven force on both sides of the boat 1 affecting the measurement accuracy of the depth measuring rod 8.

[0044] like Figure 9-11 In the preferred embodiment, the fixing unit 4 includes a base plate 401, magnetic seats 403 are provided on both sides of the base plate 401, a fixing cylinder 402 is provided in the middle of the base plate 401, a round rod 405 is telescopically provided in the fixing cylinder 402, and a removable adapter plate 406 is provided on the round rod 405, and the guide unit 2 and the detection unit 3 are respectively connected by screws 9 and the adapter plate 406.

[0045] When in use, the magnetic seat 403 can be opened or closed by a wrench. An iron plate is fixedly installed in the boat 1. The direction of the adapter plate 406 can be ensured by adjusting the position of the magnetic seat 403, and the height of the round rod 405 can be adjusted to make the position of the adapter plate 406 appropriate. The use of the magnetic seat 403 can reduce the modification of the boat 1 or the space occupied by other parts. After the measurement is completed, it will not have any other impact on the boat 1.

[0046] In the preferred solution, the two sides of the bottom plate 401 are connected to the magnetic seat 403 through the transition plate 404 and the screw 9 respectively, the magnetic seat 403 is fixedly connected to the inner side of the boat 1, the inner side of the fixing tube 402 is provided with a convex strip 407, the outer side of the round rod 405 is provided with a slide groove 409, and the slide groove 409 is slidably connected with the convex strip 407. During production, the overall convenience of use can be better improved by setting the transition plate 404. The cross section of the transition plate 404 is L-shaped, and a waist-shaped groove is provided on the transition plate 404, so that the operator can adjust the distance and height of the magnetic seats 403 on both sides. The overall locking effect is better, and the convex strip 407 and the slide groove 409 cooperate to facilitate the round rod 405 to go up and down directly, which is more convenient to operate. Through the locking of the screw 9, the overall structural stability is stronger.

[0047] In the preferred embodiment, a first through hole 408 is penetrated through the fixing cylinder 402, a first threaded hole 410 is provided on the outer side of the round rod 405, the screw 9 is inserted into the first through hole 408 and the first threaded hole 410, a square platform 411 is provided on the top of the round rod 405, a square sleeve 414 is provided on one side of the adapter plate 406, the square sleeve 414 is sleeved on the outer side of the square platform 411, a second threaded hole 413 and a second through hole 415 are respectively provided on the square platform 411 and the screw 9 is inserted into the square sleeve 414 and the square platform 411, a threaded column 412 is further provided on the top of the square platform 411, a locking ring 416 is provided on the threaded column 412, the lower side of the locking ring 416 abuts against the square sleeve 414, and the height of the square sleeve 414 is greater than the square platform 411.

[0048] By setting the square sleeve 414 and the square platform 411, the verticality between the adapter plate 406 and the bottom plate 401 can be ensured, so that when the adapter plate 406 needs to be adjusted, the bottom plate 401 can be adjusted on the inner side of the boat 1, which is more convenient to adjust. The height of the square sleeve 414 is higher than the square platform 411. Since the adapter plate 406 needs to maintain good stability and can apply a pulling force to the detection unit 3 and the guide unit 2 at the same time, the adapter plate 406 will be affected by the detection unit 3 and the guide unit 2, thereby generating a bending moment. At this time, the square sleeve 414 is further locked at the top by the locking ring 416, which ensures the structural strength of the adapter plate 406, so that the overall rigidity is strong, and the measurement is stable and efficient during the movement of the boat 1.

[0049] like Figure 12-13In the preferred solution, the guide unit 2 includes a first sleeve 201, the first sleeve 201 is sleeved on the adapter plate 406, a plurality of fourth threaded holes 205 are provided on the first sleeve 201, a square frame 203 is connected to the lower side of the first sleeve 201 through a cantilever plate 202, a plurality of partitions 204 are evenly arranged on the square frame 203, and a magnetic sensor 10 is detachably provided between two adjacent partitions 204;

[0050] The drone 7 includes a vertical rod 701 , a sensing tube 702 is disposed at the lower side of the vertical rod 701 , and the magnetic sensor 10 is used to detect and identify the position of the sensing tube 702 . The hanging rod 701 is preferably made of non-metallic material, and its outer surface has a certain elasticity. When the hanging rod 701 exceeds the limit size inside the square frame 203 and collides, it will not cause structural damage. The economic cost is low and the effect is better. The sensing tube 702 is made of metal. When the hanging rod 701 is close to the square frame 203, it can be captured by the magnetic sensor 10. At the same time, the square frame 203 is made of non-metallic material. The overall response is fast and sensitive, and the detection accuracy is high. At the same time, buzzers are respectively arranged on the left and right sides of the square frame 203. Preferably, when the hanging rod 701 is close to the left side of the square frame 203, an alarm sound such as "di di di" is emitted, and when the hanging rod 701 is close to the right side of the square frame 203, an alarm sound such as "da da da" is emitted. The alarm sounds on both sides are different. At the same time, as the distance between the hanging rod 701 and the inside of the square frame 203 changes, the frequency of the sound changes accordingly. The closer the distance, the higher the alarm frequency.

[0051] In the preferred solution, a third threaded hole 417 is provided on the adapter plate 406, a vertical rod 206 is provided on one side of the first sleeve 201, the vertical rod 206 and the third threaded hole 417 are threadedly connected, a docking head 207 is provided on the top of the vertical rod 206, a ring groove 208 is provided in the middle of the docking head 207, a locking sleeve 210 is sleeved on the docking head 207, a fifth threaded hole 211 is penetrated on the locking sleeve 210, the locking sleeve 210 is connected to the ring groove 208 by a screw 9, and alignment plates 209 are provided on both sides of the locking sleeve 210;

[0052] A mounting sleeve 705 is provided at the lower part of the drone 7, the vertical rod 701 and the mounting sleeve 705 are threadedly connected, a side panel 703 is provided on one side of the mounting sleeve 705, two infrared emitters 704 are provided on the side panel 703 in parallel at least in the height direction, the infrared emitters 704 are arranged opposite to the alignment plate 209, and the height difference between the two infrared emitters 704 is slightly smaller than the height of the alignment plate 209.

[0053] In order to ensure that the height of the sensing tube 702 relative to the square frame 203 is relatively stable, two infrared transmitters 704 are arranged on the drone 7. The two infrared transmitters 704 are respectively facing the two extreme positions in the height direction of the alignment plate 209. It only needs that the light of at least any one of the infrared transmitters 704 is within the alignment plate 209 to ensure that the sensing tube 702 can be captured by the magnetic sensor 10. The side of the alignment plate 209 facing the drone 7 is coated with a black layer, and the camera is aimed at the alignment plate 209 to detect whether the position of the infrared spot is within the alignment plate 209. The emission ports of the two infrared transmitters 704 are respectively blocked by different pattern filters. The light emitted by the upper and lower infrared transmitters 704 passes through different pattern filters and the light spots on the alignment plate 209 have different shapes. A camera is arranged on the side of the drone 7 facing the alignment plate 209. The moving direction of the vertical rod 701 in the height direction can be checked through the camera, so as to give the drone 7 a signal for corresponding adjustment.

[0054] like Figure 17-21 In the preferred scheme, the detection unit 3 includes a second sleeve 301, which is sleeved on the adapter plate 406. The second sleeve 301 is connected to the adapter plate 406 by screws 9.

The outer side of the sounding rod 8 is fixed by two oppositely arranged locking plates 305, and the two locking plates 305 are respectively connected to the support plate 303 through the adjusting unit 11. A buoy 304 is provided at the lower part of the lock plate 305, and the buoy 304 is supported on the water surface. A second wave-breaking net 306 is also provided on both sides of the support plate 303.

[0055] Before the sounding rod 8 is installed, the buoy 304 is first installed at the bottom of the lock plate 305, and then the sounding rod 8 is locked by the two lock plates 305, and then the whole is put into the water, and self-stabilized by buoyancy and deadweight, and then installed on the boat 1 through the adjustment unit 11. A bubble level 313 is also provided on the lock plate 305. The verticality of the sounding rod 8 and the water surface can be checked by the bubble level 313. By adjusting the verticality, the GNSS phase center and the geometric center of the probe head of the sounding rod 8 are in the same plane, which enhances the stability of the instrument during operation, improves the measurement accuracy, and ensures the reliability of the measurement results. The second wave-breaking net 306 can slow down or even eliminate the surge from the front of the boat 1, thereby reducing the impact of the water flow on the sounding rod 8 and ensuring the measurement accuracy.

[0057] A plurality of first supports 309 are provided on the support plate 303, a plurality of second supports 310 are provided on the locking plate 305, the adjustment unit 11 includes two threaded sleeves 1102 arranged opposite to each other, the two threaded sleeves 1102 are connected by a bidirectional threaded rod 1103, a ball head 1101 is provided at the end of the threaded sleeve 1102, and the ball heads 1101 on both sides are hinged to the first support 309 and the second support 310 respectively.

[0058] By adjusting the bidirectional threaded rod 1103, the vertical accuracy of the connection between the sounding rod 8 and the boat 1 is ensured. At the same time, the connection structure has high strength, a large adjustment range and good effect. A rubber layer is arranged on the inner side of the first clamping port 307 and the second clamping port 308, which ensures the clamping effect while avoiding damage to the surface of the sounding rod 8, and the overall use is more convenient.

[0060] Through the reciprocating motion of the cutter 504, the water plants or debris that may entangle the sounding rod 8 in the water area are pushed away, and the measurement effect is better. The reciprocating frequency of the telescopic rod 502 is adjusted to ensure the working effect of the cutter 504. At the same time, the two first wave-breaking nets 505 are located near the bow of the boat 1 to slow down or even eliminate the surge from the bow, thereby cooperating with the second wave-breaking net 306 to provide all-round protection for the sounding rod 8 from multiple directions to ensure the measurement effect.

[0061] In the preferred embodiment, a motor 506 and a disc 507 are respectively provided on both sides of the mounting seat 501, and the motor 506 drives the disc 507 to rotate.
