Description
Technical Field
[0001] The utility model relates to the technical field of anti-collision sonar testing, in particular to an anti-collision sonar ranging verification device. Background Technique
[0002] The anti-collision sonar is a sonar device for measuring the height of a submersible from the seabed. Its working principle is as follows: a short pulse with a narrow beam is emitted. The pulse generates an echo after being reflected by the seabed. By measuring the delay T of the echo relative to the emission moment, the height of the device from the seabed can be calculated.
[0003] Ranging is the main function of the anti-collision sonar. At present, the anti-collision sonar is usually tested by actual environment tests or pool tests. The actual environment test is to carry the anti-collision sonar on a ship in a natural sea area or water area, sail to a designated area, and compare the data obtained by the anti-collision sonar with the actual height to determine the function and performance of the anti-collision sonar. The economic cost and time cost are very high, and the bottom of the natural water is uneven, so stable, accurate and reliable comparison data cannot be obtained. The conventional pool test requires renting a pool from a professional test institution and entering the water in a hanging form. The economic cost and time cost are also not low. Moreover, the traditional hanging form not only requires waiting for the suspension, but also the height of the anti-collision sonar from the seabed cannot be accurately adjusted. Especially, the test verification of the minimum measurement distance of the anti-collision sonar is extremely difficult. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model

[0026] Embodiment: In combination with the attached drawings of the specification Figure 1-10 As can be seen, the present application specifically designs an anti-collision sonar ranging verification device, including a column 1, a positioning member 2, an angle code 3, a bottom plate 4, and a sliding table assembly 5; the column 1 is connected and fixed to the bottom plate 4 through the angle code 3 and is perpendicular to the bottom plate 4; the positioning member 2 is divided into an upper positioning member and a lower positioning member, both of which are installed on the side wall of the column 1, and the upper positioning member and the lower positioning member respectively correspond to the functional performance test positions of two types of anti-collision sonars; the sliding table assembly 5 is installed on the positioning member 2. The anti-collision sonar ranging verification device has a compact structure and does not require renting a large pool. Only based on this device and a small pool or bucket can the accurate test of the minimum measurement distance of the anti-collision sonar be realized; this device is compatible with two types of anti-collision sonars and solves the problem that the minimum measurement distances of the two types of anti-collision sonars are not in the same range, and has strong versatility; the anti-collision sonar is firmly fixed on the device, and the disassembly, installation, and height adjustment operations during the test are simple and convenient.
[0027] In the specific implementation process, the upper part of the side wall of the above-mentioned positioning member 2 is provided with an inclined surface, the front part is provided with a groove, and the bottom is provided with a screw pin. The sliding table assembly 5 is clamped on the positioning member 2 by means of a hook 5c and a clamping plate 5i.
[0028] In the specific implementation process, the main body of the above-mentioned sliding table assembly 5 is a hand-cranked ball screw type sliding table module 5a. One end of the slider of the sliding table module 5a is provided with a bracket assembly 5b. The guiding bottom plate 5d at the lower end of the sliding table assembly 5 and the guiding vertical plates 5e and guiding small plates 5f on both sides form a guiding structure for the extension plate 5b1.
[0029] In the specific implementation process, two scales 5g with different ranges are respectively provided on both sides of the above-mentioned sliding table assembly 5, and pointers 5h are provided on both sides of the slider of the sliding table module 5a and point to the scales on the scale 5g.
[0030] In the specific implementation process, the above-mentioned bracket assembly 5b includes a small-size clamping assembly and a large-size clamping assembly provided on the side wall of the extension plate 5b1.
[0031] In the specific implementation process, the above-mentioned small-size clamping assembly includes a small support plate 5b3 hinged to the lower side of the extension plate 5b1 and a U-shaped clamping plate 5b4 provided on the upper side of the extension plate 5b1. Glass bead set screws 5b12 are symmetrically arranged on both sides of the U-shaped clamping plate 5b4 for squeezing and limiting the outer circle of the small-size anti-collision sonar, and a small hook 5b5 is provided on the side of the extension plate 5b1 for clamping the small support plate 5b3.
[0032] In the specific implementation process, the above-mentioned large-size clamping assembly includes a large support plate 5b2 provided on the lower side of the extension plate 5b1. Above the large support plate 5b2, there is a pressing arm 5b6. One end of the pressing arm 5b6 is rotatably matched with the side wall of the extension plate 5b1. Above the pressing arm 5b6, there is a second connecting rod 5b8. One end of the second connecting rod 5b8 is rotatably matched with the side wall of the extension plate 5b1 and the other end is rotatably connected to the first connecting rod 5b7. One end of the first connecting rod 5b7 is rotatably connected to the pressing arm 5b6. A second connecting plate 5b10 is provided on the first connecting rod 5b7. A first connecting plate 5b9 is provided at the lower end of the pressing arm 5b6. A spiral spring 5b13 is provided at the lower end of the first connecting plate 5b9. A pressing head 5b11 is provided at the lower end of the spiral spring 5b13. A beveled boss is provided on the side wall of the extension plate 5b1 at the position corresponding to the second connecting rod 5b8.
[0033] In the specific implementation process, a telescopic sleeve 5b14 is provided on the above-mentioned U-shaped clamping plate 5b4. A telescopic rod 5b15 is inserted into the telescopic sleeve 5b14. The lower end of the telescopic rod 5b15 passes through the lower end face of the U-shaped clamping plate 5b4 and extends below the U-shaped clamping plate 5b4.
[0034] The working principle is as follows: The column 1 is fixedly connected and perpendicular to the bottom plate 4 through three angle codes 3. Two positioning members 2 are installed at the specified positions on the column 1. The positioning members are divided into an upper positioning member and a lower positioning member, corresponding to the functional performance test positions of two kinds of anti-collision sonars respectively. During use, according to the corresponding specifications of the anti-collision sonar, the sliding table assembly 5 is installed on the corresponding positioning member 2, and then the anti-collision sonar to be tested is fixed on the sliding table assembly 5. At this time, the anti-collision sonar is perpendicular to the bottom plate 4. With the help of the sliding table module 5a, the anti-collision sonar can move up and down within a certain range, meeting the test operation of the functional performance of the anti-collision sonar.
[0035] The sliding table assembly 5 can be conveniently fixed on the positioning member 2 by means of a hook 5c and a clamping plate 5i. The specific principle is as follows: There is a bevel on the upper part of the side wall of the positioning member 2, a groove in the front part, and a screw pin at the bottom; the hook 5c is a hook-shaped structure with a bevel. When entering the positioning member 2 from top to bottom, the bevels of the two just fit, and gravity makes the hook 5c and the positioning member 2 fit tightly in the horizontal front and back directions; the clamping plate 5i can just be embedded into the groove in the front part of the positioning member 2 in the left and right directions. The groove restricts the left and right movement of the clamping plate 5i. At the same time, the screw pin at the bottom of the positioning member 2 enters the U-shaped notch position of the clamping plate 5i, which can restrict the front and back movement of the clamping plate 5i. Therefore, no additional locking is required and it can be fixed by relying on the self-weight of the sliding table assembly 5.
[0036] The main body of the slide table assembly 5 is a hand-operated ball screw type slide table module 5a, which can provide a certain range of displacement and self-locking. The guiding bottom plate 5d at the lower end of the slide table assembly 5 and the guiding vertical plates 5e and guiding small plates 5f on both sides form a guiding structure for the extension plate 5b1, which can make the bracket assembly 5b run up and down more reliably; two scales 5g with different ranges are respectively arranged on both sides of the slide table assembly 5. Pointers 5h are arranged on both sides of the slider of the slide table module 5a and point to the scales of the scales 5g. Collision avoidance sonars of different specifications respectively read the scales of the corresponding scales 5g.
[0037] The bracket assembly 5b can clamp collision avoidance sonars of two specifications:
[0038] When clamping the small-sized collision avoidance sonar A, lift the small hook 5b5 and lower the small support plate 5b3. At this time, the small support plate 5b3 will be in a horizontal posture, pull up the connecting plate two 5b10 obliquely upward, and the connecting rod two 5b8 will drive the pressing arm 5b6 to lift. Continue to push the pressing arm 5b6 to make it lean against the extension plate 5b1. Rotate the telescopic rod 5b15 clockwise so that the telescopic rod 5b15 moves downward, and the front end can block the connecting plate two 5b10; at this time, place the lower end of the small-sized collision avoidance sonar A in the groove of the small support plate 5b3, and push the upper part of the small-sized collision avoidance sonar A to make it lean against the U-shaped clamping plate 5b4. The outer circle of the small-sized collision avoidance sonar A contacts the glass bead set screw 5b12 and squeezes the front end telescopic pin to contract. When the center line of the small-sized collision avoidance sonar A passes through the glass bead set screw 5b12, its telescopic pin extends by relying on the internal spring and continuously contacts the outer wall of the small-sized collision avoidance sonar A, and push the small-sized collision avoidance sonar A until it leans against the U-shaped clamping plate 5b4 and stops. At this time, the extrusion of the telescopic pin of the glass bead set screw 5b12 can provide a certain locking force for the small-sized collision avoidance sonar A; to remove the small-sized collision avoidance sonar A, just pull it away from the U-shaped clamping plate 5b4.
[0039] When clamping the large-sized collision avoidance sonar B, lift the small support plate 5b3. When it approaches the extension plate 5b1, it will jack up the small hook 5b5. When it reaches the side wall groove of the small support plate 5b3, it will no longer support the small hook 5b5, and the small hook 5b5 will fall by gravity and hook the small support plate 5b3. Place the lower end of the large-sized collision avoidance sonar B in the groove of the large support plate 5b2, rotate counterclockwise or directly pull up the telescopic rod 5b15 to make it move upward. The front end of the telescopic rod 5b15 no longer blocks the second connecting plate 5b10, and the falling pressure arm 5b6 makes its pressure head 5b11 press on the large-sized collision avoidance sonar B. Continuously press down the second connecting plate 5b10, the pressure arm 5b6 presses down, and the pressure head 5b11 is supported by the large-sized collision avoidance sonar B and no longer moves downward. At this time, the spiral spring 5b13 at the rear end is compressed. When the included angle between the first connecting rod 5b7 and the second connecting rod 5b8 reaches 180°, the spiral spring 5b13 reaches the maximum compression amount. Continuously press down the second connecting plate 5b10. After the included angle between the first connecting rod 5b7 and the second connecting rod 5b8 breaks through 180°, the elastic force provided by the spiral spring 5b13 makes the second connecting plate 5b10 tend to move downward continuously. However, the inclined plane boss on the extension plate 5b1 blocks the movement of the second connecting rod 5b8. At this time, the pressure arm 5b6 is locked, and the large-sized collision avoidance sonar B is locked. To remove the large-sized collision avoidance sonar B, only need to pull up the second connecting plate 5b10 obliquely upward to release the lock on the pressure arm 5b6, then lift the pressure arm 5b6 and make it approach the extension plate 5b1. When the second connecting plate 5b10 touches the front-end inclined plane of the telescopic rod 5b15, it can push the telescopic rod 5b15 to move upward. When the second connecting plate 5b10 no longer contacts the telescopic rod 5b15, the telescopic rod 5b15 falls by gravity, and its front end blocks the second connecting plate 5b10, making the whole in the preparation state for measuring the next large-sized collision avoidance sonar B.
[0040] When measuring the collision avoidance sonar, if measuring the small-sized collision avoidance sonar A, the slide table assembly 5 should be installed on the upper positioning part correspondingly. If measuring the large-sized collision avoidance sonar B, the slide table assembly 5 should be installed on the lower positioning part correspondingly. After installation in place, place the whole collision avoidance sonar ranging verification device in the pool, rotate the handle to make the bracket assembly 5b at the highest position, adjust the water level so that it just submerges the large support plate 5b2, clamp the collision avoidance sonar on the bracket assembly 5b, power on the collision avoidance sonar for testing. The pulsed beam emitted by the collision avoidance sonar passes through the central opening of the large support plate 5b2 or the small support plate 5b3, propagates to the bottom plate 4 and then the reflected pulse is transmitted back to the collision avoidance sonar transducer. The upper computer of the collision avoidance sonar displays the height data of the distance from the collision avoidance sonar to the bottom plate measured. Adjust the height of the collision avoidance sonar downward and read and compare the values of the slide table scale 5g and the measurement data of the collision avoidance sonar in real time. When the difference between the two exceeds the specified range, the minimum measurement distance of the collision avoidance sonar can be obtained.
