[0048] The present invention will be further explained below with reference to specific embodiments.

[0049] See also Figures 1-6 , an embodiment of the present invention provides a ship detection device, the ship detection device comprising:

[0050] A guide bar 1, wherein the guide bar 1 is connected to the ship via a mounting plate;

[0051] A detection box 6 is slidably connected to the guide bar 1 via a guide assembly, and a second rangefinder 32 is provided on the top of the detection box 6 for detecting the distance between the top of the detection box 6 and the mounting plate. A hanging hook 5 is also provided on the top of the detection box 6 for connecting a traction rope; the second rangefinder 32 can be a radar or an infrared rangefinder, etc., which is not specifically limited here;

[0052] A buoyancy member 9 is provided at the bottom of the detection box 6; wherein the buoyancy member 9 is an air bag;

[0053] A wave-sensing control component for adjusting the working state of the rangefinder 2 32, wherein the wave-sensing control component is disposed in the detection box 6;

[0054] And a driving component for driving the wave-sensing control component to work.

[0055] In an embodiment of the present invention, a mounting plate is used to fix the guide bar 1 to the ship's side outer plate on both sides of the bow, midship or stern of the hull, and a crane is provided on the mounting plate, and the traction end of the crane is fixedly connected to the suspension hook 5, wherein the crane can adopt the existing public technology. When in use, the crane can make the detection box 6 slowly move down along the guide bar 1 by cooperating with the guide assembly until the buoyancy member 9 contacts the sea surface. At this time, the traction end of the crane continues to move down, so that the detection box 6 and the buoyancy member 9 can float naturally on the sea surface without the action of traction. The distance L1 between the top of the detection box 6 and the mounting plate can be measured in real time by using the rangefinder 32. Assuming that the total height of the detection box 6 and the buoyancy member 9 is L3, the distance L2 from the mounting plate to the bottom of the ship minus the distances L1 and L3 is the draft depth, wherein L1 is the average value of multiple measurements. When the waves are large, the waves will push the buoyancy member 9 to move. The detection box 6 is made to move back and forth in the length direction of the guide bar 1. At this time, the driving component will drive the wave-sensing control component to work. According to the degree of influence of the waves on the detection box 6, that is, the movement amplitude of the detection box 6 on the guide bar 1, the wave-sensing control component will realize different movement states, and control the switch state of the rangefinder 2 32 according to the different movement states. That is, within the set influence range, the rangefinder 2 32 works normally and can realize the draft depth measurement. If the influence exceeds the range, the rangefinder 2 32 stops working, thereby reducing the measurement error. Compared with the prior art, the present invention avoids the problem that the current method for detecting the draft of a ship cannot realize the control of the working state of the detection equipment according to the degree of influence of the waves on the detection equipment, the scope of application is limited, and the detection accuracy is seriously affected by the coordinated arrangement of the wave-sensing control component, the driving component and the rangefinder 2 32.

[0056] In one embodiment of the present invention, see Figures 1-6 , the guide assembly includes:

[0057] Support rods 10, said support rods 10 being fixedly mounted on the detection box 6, and two support rods 10 are provided at both upper and lower ends of the detection box 6;

[0058] And the limiting grooves 2 are opened on both sides of the guide bar 1, and the ends of the support rods 10 are rotatably mounted with guide wheels 3, and the guide wheels 3 move in the limiting grooves 2;

[0059] The surface of the guide wheel 3 is covered with a rubber layer for increasing friction, and the rubber layer is made of one of chloroprene rubber, ethylene propylene rubber and fluororubber with anti-corrosion effect, which is not specifically limited here.

[0060] In this embodiment, the coordination of the limiting groove 2, the guide wheel 3 and the support rod 10 facilitates clamping the detection box 6 onto the guide bar 1. The guiding effect of the limiting groove 2 can prevent the guide wheel 3 from falling off from the guide bar 1, thereby improving the stability of the detection box 6 during movement.

[0063] and a conversion assembly for driving the range control plate 19 to move within the rectangular groove 20;

[0064] The rangefinder 18 is an infrared rangefinder;

[0068] A guide groove 22 is provided in the detection box 6, in which an adjustment block 21 is slidably mounted, and a support shaft 31 is rotatably mounted on the adjustment block 21;

[0069] A driving rod 16, one end of which is rotatably connected to a supporting shaft 1 26, and a connecting shaft 2 27 is fixedly mounted on the other end of the driving rod 16, and the connecting shaft 2 27 is rotatably connected to an end of the connecting block 15 away from the connecting shaft 1 25;

[0070] An adjusting rod 17, one end of which is rotatably connected to the support shaft 31, and the other end of which is rotatably connected to the connecting shaft 27;

[0071] and a precision adjustment assembly for driving the adjustment block 21 to move in the guide groove 22;

[0072] The guide groove 22 is an arc-shaped structure;

[0073] The precision adjustment component includes:

[0074] A second support shaft 29 is rotatably mounted in the detection box 6, and an L-shaped support seat 28 is fixedly mounted on the second support shaft 29;

[0075] and a threaded rod 30 rotatably mounted on an L-shaped support seat 28, wherein the L-shaped support seat 28 is further provided with a motor 23 for driving the threaded rod 30 to rotate, and an internal threaded hole for threaded connection with the threaded rod 30 is provided on the support shaft 31;

[0076] The drive assembly includes:

[0077] A horizontal plate 11 is fixedly mounted on the outside of the detection box 6, a rotating shaft 8 is rotatably mounted on the horizontal plate 11, and a driving gear 7 is fixedly mounted on the rotating shaft 8, and a rack 4 is provided on the guide bar 1 to mesh with the driving gear 7;

[0078] And the second rotating shaft 13 is rotatably mounted on the side wall of the detection box 6, and the second rotating shaft 13 and the first rotating shaft 8, as well as the second rotating shaft 13 and the third rotating shaft 14 are connected through a gear set 12; wherein the connection between the second rotating shaft 13 and the detection box 6 is provided with a waterproof structure, and the waterproof structure adopts a sealing ring, which is not specifically limited here, and the gear set 12 is two sets of mutually meshing bevel gears.

[0079] The gear 7 is rotated by the rack 4 through the movement in the longitudinal direction of the guide bar 1. The gear 7, the shaft 1 8, the gear set 12 and the shaft 2 13 are matched to drive the shaft 3 14 to rotate. The shaft 3 14 can drive the conversion handle 24 to rotate. The conversion handle 24 rotates forward or reverse and cooperates with the limiting effect of the adjusting rod 17. The connecting block 15 can push or pull the driving rod 16 up or down, thereby driving the range control plate 19 to move in the rectangular groove 20 by the support shaft 1 26. The motor 23 can drive the threaded rod 30 to rotate, thereby driving the support shaft 3 31 to move. The support shaft 3 31 can drive the adjusting block 21 to move in the guide groove 22, thereby adjusting the end position of the adjusting rod 17, so that the rotation center point of the adjusting rod 17 moves downward (that is, the support shaft 3 31 moves downward). In this case, the highest point position of the adjustment rod 17 moving away from one end of the support shaft 3 31 can be pushed higher, thereby increasing the moving range of the range control plate 19 and realizing the adjustment of the moving range of the range control plate 19. The distance between the range control plate 19 and the bottom of the rectangular groove 20 can be measured by the rangefinder 18, which is recorded as H. After the buoyancy member 9 floats on the sea surface, the distance between the range control plate 19 and the bottom of the rectangular groove 20 is set to the initial value, which is recorded as h. When the buoyancy member 9 and the detection box 6 float up and down with the waves, the driving component can drive the wave-sensing control component to work, and then H changes. When the difference between H and h is within the predetermined range, the rangefinder 2 32 works normally, otherwise it stops working. By adjusting the moving range of the range control plate 19, the range of the difference between H and h can be adjusted, and it can adapt to a larger or smaller predetermined range, thereby realizing precision adjustment, further improving the applicable range, and improving measurement accuracy.
