Description

Technical Field

[0001] The utility model relates to the technical field of ocean acoustic detection, in particular to an assembled ocean sonar fixing and installation device. Background Art

[0002] The ocean underwater sonar detection system consists of an underwater sonar transmitter, antenna, attitude indicator, and deck control unit. The typical installation method is to tie or secure the sonar probe to the side of the ship using hemp rope or a standard extension rod. However, since standard extension rods or ropes cannot be tightly attached to the hull, the vibration is amplified by the hull's shaking, causing errors in the detection results.

[0003] The impact of ocean currents often causes the probe to tilt, deflect, and shift, resulting in positioning distortion and errors in the side scanning process. In particular, at high speeds or in complex sea conditions, ordinary connection devices cannot guarantee the stability of the sonar probe, further affecting the side scanning quality and causing increasing errors in the sounding results.

[0004] At the same time, surveyors also need to fix the antenna and angle attitude meter separately in the survey vessel, and then measure the distance in the X, Y, and Z directions between the sonar probe and the antenna and angle attitude meter to accurately calculate the sea area terrain information and position information. This process takes more and more time as the survey vessel grows, and human error inevitably leads to measurement errors. The angle attitude meter is often placed at the center of gravity of the survey vessel, and the distance from the sonar transmitter increases with the size of the survey vessel, which will never cause calibration errors, namely roll, pitch, and heading errors.

[0005] Using hemp rope or ordinary fixing devices, it is difficult to ensure that the depth sounding system is perpendicular to the ship at 90 degrees. The slight inclination will increase sharply over time, thus causing random installation errors.

[0006] The assembled connecting rod increases the height of the antenna and reduces the positioning error caused by signal influence. Utility Model Content

[0007] In order to solve the problems in the above-mentioned background technology, the present application provides an assembled ocean sonar fixed installation device, which can simultaneously achieve the same horizontal and vertical coordinates of key equipment such as positioning antennas and angle attitude meters relative to the sonar probe in the coordinate system, ensuring that the entire detection system has good signal strength, equipment stability sufficient to withstand the impact of sea tides, effectively reducing errors, and ensuring high-quality side scanning data.

[0008] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0009] Assembled ocean sonar fixed installation device, including:

[0010] A connecting rod, wherein the connecting rod is fixed as a whole by screwing a detachable upper rod and a lower rod; the connecting rod is provided with uniform scales throughout, the middle section is provided with at least three positioning holes, and the lower section is provided with a fixing ring for fixing the ship cable; the bottom of the lower rod is a circular connecting plate with a threaded hole;

[0011] A clamp is sleeved to fasten the hull railing and the connecting rod, and includes symmetrically arranged fixing clamping parts, the fixing clamping parts are formed by tightening the clamp groove and the clamp hoop with reduced diameters, and the clamp groove is provided with a threaded through groove, and the ends of the adjusting bolt are screwed into the threaded through groove;

[0012] The stabilizing device is T-shaped as a whole and includes a base and a vertical member for fixing. The base is provided with a fixing hole group for fixing to the hull; the vertical member is provided with a positioning hole that is consistent with the middle section of the connecting rod;

[0013] A tripod is composed of a horizontal plate, a vertical plate and an oblique plate. A tripod clamp is fixed on the vertical plate for fixing with the connecting rod. A threaded hole is provided on the horizontal plate for fixing an angle attitude meter.

[0014] An antenna connecting rod, wherein both ends of the antenna connecting rod have reducing thread sections, the top end of the antenna connecting rod is fixedly connected to the antenna via the reducing thread section, and the bottom end is fixedly connected to the connecting rod via the reducing thread section;

[0015] A ship cable, one end of which is connected to the fixing ring, and the other end of which is fixedly connected to the railing of the hull through a fine-tuning bolt.

[0016] Compared with the existing technology, this application adopts an assembled concept and uses a multi-section connecting rod, antenna connecting rod, mobile tripod, stabilizing device, split clamp and fixed steel cable technical solution to achieve the goal of stably, efficiently and conveniently fixing the ocean sonar detection system on the side of the survey ship, and at the same time achieve the same horizontal and vertical coordinates of key equipment such as positioning antenna and angle attitude meter relative to the sonar probe in the coordinate system, ensuring that the entire detection system has good signal strength, equipment stability sufficient to withstand the impact of sea tides, effectively reducing errors, and ensuring high-quality side scanning data technical effects.

[0017] Preferably, the fixing hole group on the base includes round holes and L-shaped holes, wherein the round holes are used to secure to the hull railings via bolts, and the L-shaped holes are secured to the hull deck, and at least four L-shaped holes are provided. Based on this solution, the stabilization device can be better fixed to the hull railings and deck, enhancing the stability between the connecting rod and the hull.

[0018] Specifically, fixing bolts are installed in the positioning holes to secure the vertical member to the connecting rod. The vertical member is also provided with an arched ring and ring nut to strengthen the horizontal fastening of the vertical member and the connecting rod. Passing the bolts and arched rings through the positioning holes further strengthens the horizontal stability of the vertical member and the connecting rod, ensuring greater stability between the connecting rod and the hull railing.

[0019] Furthermore, there are at least three cables, which are respectively connected to the bow, stern and railings in the middle of the ship.

[0020] Furthermore, the fine-tuning bolt has a round screw head and a hook screw head at each end, with a separate threaded post at the end. The threaded post is screwed onto a threaded housing. The distance between the two threaded posts is adjusted through the threaded housing, thereby achieving fine-tuning of the tightening of the wire cable.

[0021] A method for improving sonar depth sounding accuracy comprises the following steps:

[0022] S1: Drill holes on one side of the hull to fix and install the stabilizing device;

[0023] S2: After the connecting rod is assembled, the top end is installed with the positioning antenna through the antenna connecting rod;

[0024] S3: Fix the connecting rod to the hull through a stabilizing device;

[0025] S4: Fix the angle attitude meter on the horizontal board and fix the tripod on the connecting rod;

[0026] S5: Adjust the clamp to ensure that the connecting rod and the railing of the hull are firmly installed;

[0027] S6: Connect the cable to the fixed ring and the railing to keep the sonar equipment vertical.

[0028] Furthermore, the specific steps of fixing and installing in step S3 include:

[0029] S301: Insert bolts into the positioning holes to secure the stabilizing device and the connecting rod;

[0030] S302: Pass the arched ring through the vertical piece and the connecting rod to stabilize it horizontally.

[0031] Furthermore, the process of adjusting the fixture in step S5 is as follows:

[0032] S501: Clamp the fixing parts at both ends of the clamp onto the railing and the connecting rod respectively;

[0033] S502: Turn the distance adjusting bolt to keep the connecting rod in a horizontal state and tighten it, then lock the clamp.

[0034] Furthermore, in step S6, after the ship cables are connected to the railings and fixing rings at the bow, stern and midship, the fine-tuning bolts are rotated and tightened simultaneously to keep the sonar equipment vertically stable.

[0035] The beneficial effects of the utility model are:

[0036] 1. The split clamp of the utility model can fill the distance between the assembled connecting rod and the railing of the measuring ship, and is suitable for various ship types; and then further tightened by the clamping hoop, the connecting rod and the hull railing are integrated into one, which can improve the stability of the equipment and reduce the jitter error caused by the jitter of the equipment itself.

[0037] 2. The entire set of survey ship fixing devices of the utility model adopts an assembled concept, which is convenient for installation and removal. The fixing and restraint by the fixing holes, positioning holes and assembled connecting rods can significantly reduce the installation error.

[0038] 3. The assembled connecting rod of the utility model has its own scale, which makes the assembly safe and convenient for transportation. The entire sounding system is fixed by cooperating with the fixing device of the survey ship. The horizontal and vertical coordinates of the positioning antenna and the angle attitude meter are fixed relative to the sonar probe in the coordinate system, which can significantly reduce the measurement error.

[0039] 4 The mobile tripod of the utility model can fix the angle attitude meter on the connecting rod. Since the connecting rod has its own scale, it is convenient to measure the distance between different devices, reducing measurement errors. In particular, the horizontal and vertical coordinates of the angle attitude meter are fixed relative to the sonar transmitting device in the coordinate system, which can significantly reduce calibration errors (including roll, pitch, and heading) and measurement errors.

[0040] 5 The antenna assembly of the utility model can connect the assembled connecting rod and the positioning antenna, which on the one hand increases the height of the positioning antenna and enhances the signal; on the other hand, the horizontal and vertical coordinates of the antenna relative to the sonar transmitting device are the same in the coordinate system, which reduces positioning error and measurement error.

[0041] 6. The fine-tuning bolts of the three front and rear bottom steel cables of the utility model are used to further fix the stability of the sonar transmitting device and maintain a high verticality, resist the offset, tilt and displacement caused by the impact of ocean currents on the equipment at high speeds in the marine environment, and effectively reduce the process error during the side scanning process.

[0053] Example

[0054] The assembled ocean sonar fixed installation device of this utility model can be found in Figure 1-4 ,include:

[0055] Connecting rod 1, which is fixed together by a detachable upper rod 101 and a lower rod 102 screwed together; the connecting rod 1 is provided with a uniform scale throughout, used to indicate the vertical depth, and the middle section of the connecting rod 1 is provided with three positioning holes 103, and the lower section is provided with a fixing ring 104 for fixing the ship cable 10; the bottom of the lower rod 102 is a circular connecting plate 105 with a threaded hole;

[0056] The clamp 2 is sleeved and fastened to the hull railing 3 and the connecting rod 1, and includes a symmetrically arranged fixing clamp portion, which is formed by the clamp groove 201 and the clamping hoop 202 being tightened by reducing the diameter. A threaded through groove 203 is opened in the middle of the clamp groove 201, and the ends of the adjustable bolt 204 are screwed into the threaded through groove 203 to connect;

[0057] The stabilizing device 4 is T-shaped as a whole and includes a base 401 and a vertical member 402 fixed thereto. The base 401 is provided with a set of fixing holes for fixing to the hull; the vertical member 402 is provided with a positioning hole 103 that is consistent with the middle section of the connecting rod 1;

[0058] The tripod 5 is composed of a horizontal plate 501, a vertical plate 502 and an inclined plate 503. The vertical plate 502 is fixed with a tripod clamp 504 for fixing with the connecting rod 1. The horizontal plate 501 is provided with a threaded hole 505 for fixing the angle attitude meter 6;

[0059] Antenna connecting rod 7, both ends of which are provided with reducing thread segments 701. The top end of the antenna connecting rod 7 is fixedly connected to the antenna 8 via the reducing thread segment 701, and the bottom end is screwed and fixedly connected to the internal thread groove 106 at the top end of the connecting rod 1 via the reducing thread segment 701.

[0060] A ship cable 10 , one end of which is connected to the fixing ring 104 , and the other end of which is fixedly connected to the railing 3 of the ship body via a fine-tuning bolt 11 .

[0061] The utility model firmly fixes the ocean sonar detection system (including antenna 8, angle attitude meter 6 and sonar 12) on one side of the survey ship through a series of strengthening and fixing devices such as an assembled connecting rod 1, a stabilizing device of the survey ship, and a split clamp 2;

[0062] Combining the antenna connecting rod 7 and the movable tripod 5, the horizontal and vertical coordinates of the positioning antenna 8 and the angle attitude meter 6 are the same relative to the sonar 12 in the coordinate system, which not only reduces the measurement error, but also reduces the roll, pitch and bow errors. The extended connecting rod 1 improves the signal strength and further reduces the positioning error; the connecting rod 1 has its own scale, which saves the time of measurement between different devices and reduces the measurement error; the split fixture 2 reduces the jitter error, the measuring ship fixing device reduces the safety error, and finally, through the cooperation of the front and rear and bottom cables 10, it is ensured that the ocean sonar detection device maintains a high stability even at high speeds, reducing process errors.

[0063] The entire set of equipment adopts an assembled concept and does not require fixed welding and complicated processes. It is not only convenient to transport, but also easy to install and dismantle, has a low cost, and can be suitable for a variety of ship types; the highly integrated connecting rods and various equipment greatly save measurement time. For traditional ocean sonar depth sounding methods, the utility model reduces jitter error, calibration error (roll, pitch, bow), safety error, measurement error, process error and positioning error. The utility model can significantly improve the working efficiency and data quality of ocean sonar depth sounding technology.

[0064] See also Figure 6-7 The method for using the supporting device of the utility model on a test ship includes the following steps:

[0065] 1. Measure and drill 4 fixing nuts on the survey ship;

[0066] 2. Fix the measuring vessel's stabilizing device 4 to the vessel's side by using four fixing nuts and the fixing holes on the base 401.

[0067] 3. Connect the upper and lower ends of the assembled connecting rod through the threaded connection section;

[0068] 4. Connect the connecting rod 1 to the antenna 8 through the antenna connecting rod 7;

[0069] 5. Align the vertical piece 402 with the positioning holes 103 on the connecting rod 1 and insert bolts and nuts to vertically secure the connecting rod 1 and antenna 8 to the survey vessel securing device 4.

[0070] 6. Then, fix the assembled connecting rod 1 and the positioning rod 8 to the fixing device in the horizontal direction through the arched ring 405 and the fixing hole 103 in conjunction with the nut 406;

[0071] 7. Fix the angle attitude meter 6 on the horizontal plate 501 of the mobile tripod 5 by fixing bolts and nuts;

[0072] 8. Insert bolts and nuts through the tripod clamp 504 to secure the mobile tripod 5 to the assembled connecting rod 1;

[0073] 9. Adjust the two clamping parts of the split clamp 2 by using the distance adjusting bolts 204 until they just fill the gap between the assembled connecting rod 1 and the railing 3 of the survey vessel, and then lock them with the clamp 202;

[0074] 10. Fix one end of the front and rear and bottom-crossing steel cables 10 to the cable fixing ring 103 at the lower section of the assembled connecting rod 1, and fix the other end to the railing 3 on the side of the ship. Fine-tune the verticality of the ocean sonar detection equipment through the fine-tuning bolts 11 and tighten them at the same time to further improve the overall stability and maintain verticality.

[0075] See also Figure 1 The assembled connecting rod 1 of the present invention is fixedly connected by a split upper rod 101 and a lower rod 102 that are screwed together through a middle thread, which facilitates disassembly while extending the length of the connecting rod 1, increasing the height of the antenna 8 and ensuring the signal strength; a fixing ring 103 of the ship cable 10 is provided at the lower part of the lower rod 102, which facilitates the fixation of the three fixed ship cables 10 to the connecting rod 1 and the calibration of the verticality; no less than 3 positioning holes 103 are provided in the middle section of the lower rod 102, and the spacing between the positioning holes 103 is the same as that on the vertical piece 402 of the survey ship stabilizing device 4, and is used to fix the above vertical piece 402 and the connecting rod 1 together with screws and nuts.

[0076] The connecting rod 1 has a uniform and continuous scale, which provides accurate and easy-to-read values for measuring the distance and draft between different devices, reducing the dynamic and static draft errors of the survey ship and the measurement errors between different devices;

[0077] See also Figure 2The clamp 2 is divided into two front and rear fixing clamping parts, which can be sleeved on both ends of the distance adjusting bolt 204 through the hollow threaded threaded groove 203. The distance between the front and rear fixing clamping parts can be adjusted by rotating the thread. The fixing clamping part includes a clamp groove 201 with a semicircular groove in the middle. The clamp groove 201 is mirror-symmetrical on the left and right. The clamp groove 201 has the same diameter as the assembled connecting rod 1 and the ship railing 3, and can firmly fill the gap between the assembled connecting rod 1 and the survey ship railing 3; because the clamp groove 201 is a groove, the assembled connecting rod 1, the split clamp 2, and the survey ship railing 3 can be fixed as a whole with the clamp 202, thereby increasing the stability of the entire underwater sonar detection device while reducing the jitter caused by the excessively long connecting rod of the sonar detection system.

[0078] See also Figure 3-4 The stabilizing device 4 is T-shaped and primarily consists of a transverse base 401 and a vertical member 402. The fixing holes on the base 401 include circular holes 403 and L-shaped holes 404. The circular holes 403 are used to secure to the hull's railing 3 via bolts, while the L-shaped holes 404 are secured to the hull's deck. At least four L-shaped holes 404 are provided. This solution allows the stabilizing device 4 to be more securely attached to the hull's railing 3 and deck, enhancing the stability between the connecting rod 1 and the hull.

[0079] At the same time, the vertically arranged positioning holes 103 on the vertical member 402 are spaced in the same distance as the middle portion of the lower end of the assembled connecting rod 1, facilitating the vertical fastening of the stabilizing device 4 to the lower section of the connecting rod 1 via screws and nuts. The vertical member 402 is also provided with an arched ring 405 and a ring nut 406 to strengthen the horizontal fastening of the vertical member 402 to the connecting rod 1. Bolts passing through the positioning holes 103 and the arched ring 405 further strengthen the horizontal fastening of the vertical member 402 to the connecting rod 1, ensuring greater stability between the connecting rod 1 and the hull railing 3.

[0080] The tripod 5 consists of a horizontal plate 501, a vertical plate 502, and an inclined plate 503, wherein the inclined plate 503 mainly plays a stabilizing role. The horizontal plate 501 is provided with a circular opening matching the openings around the angle attitude meter 6, so that the angle attitude meter 6 can be fixed to the horizontal plate 501 of the tripod 5 by screws and nuts; the tripod clamp 504 is substantially the same size as the assembled connecting rod 1, one end of the tripod clamp 504 is fixed to the tripod 5, and the other end is opened and sleeved on the connecting rod 1 and fixed to the connecting rod 1 by a locking bolt and nut. Since the connecting rod 1 is provided with a scale, the distance between the angle attitude meter 6 and the sonar 12 and the antenna 8 can be conveniently and accurately measured;

[0081] The mobile tripod 5 connects and fixes the angle attitude meter 6 and the sonar 12 transmitting device so that the two are approximately equal in the coordinate system XY, reducing the roll, pitch and yaw errors of the angle attitude meter relative to the sonar transmitting device.

[0082] The antenna connecting rod 7 has a reducing thread section 701 on both the upper and lower ends. The lower section is used to screw and fix with the internal thread on the upper end of the assembled connecting rod 1, and the upper section is used to connect with the positioning antenna 8. The main functions of the antenna connecting rod 7 are:

[0083] 1. Raising the position of the positioning antenna 8 helps to enhance the signal;

[0084] 2. The horizontal and vertical coordinates of the positioning antenna 8 are the same relative to the sonar 12 in the coordinate system. Based on the built-in scale of the connecting rod 1, the distance between different devices can be easily read, saving measurement time and improving work efficiency.

[0085] The antenna connecting rod 7 increases the height of the positioning antenna 8, improves the signal strength, improves the positioning accuracy of the entire system, reduces the positioning error, and also reduces the measurement error caused by measurements between different settings;

[0086] See also Figure 5-6 There are three adjustable steel wire cables 10, namely the front cable 1001, the rear cable 1002 and the bottom cable 1003. One end of each cable 10 is fixed to the cable fixing ring 103 at the lower part of the lower section of the assembled connecting rod 1, and the two are inseparable by fixing the hanging ring lock; at the same time, the other end is fixed to the railing 3 at a distance on the left and right sides of the connecting rod 1 and the symmetrical hull railing 3 by fine-tuning bolts 11;

[0087] See also Figure 7 The fine-tuning bolt 11 has a round screw head 1101 and a hook-shaped screw head 1102 at either end, terminated by a separate threaded post 1103 that screws outwardly into a threaded housing 1104. The distance between the two threaded posts 1103 is adjusted via the threaded housing 1104, thereby achieving fine-tuning of the tightening of the steel cable 10. This tightening of the cable 10 improves the stability and position of the underwater sonar 12, ensuring the stability of the entire detection system even in complex waters and at high speeds. This ensures the probe maintains high verticality and prevents tilt, flipping, or displacement.
