For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0027] The present invention will be further explained and illustrated below in conjunction with specific embodiments.
[0028] Please refer to Figures 1-6 , a ship detection device provided by an embodiment of the present invention, the ship detection device includes: A guide bar 1, which is connected to the ship through a mounting plate; A detection box 6, which is slidably connected to the guide bar 1 through a guiding component, and a distance measuring instrument two 32 for detecting the distance between the top of the detection box 6 and the mounting plate is provided at the top of the guide bar 1, and a suspension hook 5 for connecting a towing rope is further provided at the top of the detection box 6; wherein the distance measuring instrument two 32 can be a radar or an infrared distance measuring instrument, etc., and no specific limitation is made here; A buoyancy member 9, which is arranged at the bottom of the detection box 6; wherein the buoyancy member 9 is an airbag; A wave induction control component for adjusting the working state of the distance measuring instrument two 32, which is arranged in the detection box 6; And a driving component for driving the wave induction control component to work.
[0029] In an embodiment of the present invention, a guide bar 1 is fixed to the outer hull plates on both sides of the bow, midship or stern of the hull by means of a mounting plate, and a crane is provided on the mounting plate. The traction end of the crane is fixedly connected to a suspension hook 5. The crane can adopt the existing publicly available technology. During use, through the cooperative setting with the guiding assembly, the detection box 6 can be slowly lowered along the guide bar 1 until the buoyancy member 9 contacts the sea surface. At this time, the traction end of the crane continues to move downward, so that the detection box 6 and the buoyancy member 9 can float naturally on the sea surface without the action of traction force. A second rangefinder 32 can be used to measure the distance L1 between the top of the detection box 6 and the mounting plate in real time. Assuming the total height of the detection box 6 and the buoyancy member 9 is L3, the draft depth is obtained by subtracting L1 and L3 from the distance L2 between the mounting plate and the bottom of the ship. Here, L1 is the average value of multiple measurements. When the sea waves are large, the sea waves will push the buoyancy member 9 to move, causing the detection box 6 to reciprocate in the length direction of the guide bar 1. At this time, the driving assembly will drive the sea wave induction control assembly to work. According to the influence degree of the sea waves on the detection box 6, that is, the movement amplitude of the detection box 6 on the guide bar 1, the sea wave induction control assembly will achieve different movement states and control the switch state of the second rangefinder 32 according to different movement states. That is, within the set influence range, the second rangefinder 32 works normally and can achieve draft depth measurement. If the influence exceeds this range, the second rangefinder 32 stops working to reduce the measurement error. Compared with the prior art, through the cooperative setting of the sea wave induction control assembly, the driving assembly and the second rangefinder 32, the present invention avoids the problem that the current detection method of the ship draft depth cannot control the working state of the detection equipment according to the influence degree of the sea waves on the detection equipment, resulting in limited application range and seriously affecting the detection accuracy.
[0030] In an embodiment of the present invention, please refer to Figures 1-6 , the guiding assembly includes: Support rods 10, the support rods 10 are fixedly installed on the detection box 6, and two support rods 10 are provided at both the upper and lower ends of the detection box 6; And limiting grooves 2 opened on both sides of the guide bar 1. Guide wheels 3 are rotatably installed at the ends of the support rods 10, and the guide wheels 3 move in the limiting grooves 2; A rubber layer for increasing friction is covered on the surface of the guide wheel 3, and the rubber layer is made of one of chloroprene rubber, ethylene propylene rubber and fluororubber with anti-corrosion effect, and no specific limitation is made here.
[0031] In this embodiment, through the cooperative setting of the limiting groove 2, the guide wheel 3 and the support rod 10, it is convenient to clamp the detection box 6 onto the guide bar 1. By using the guiding function of the limiting groove 2, it is possible to prevent the guide wheel 3 from falling off the guide bar 1 and improve the stability of the detection box 6 during movement.
[0032] In an embodiment of the present invention, please refer toFigures 1-6 , the wave induction control component includes: A rectangular groove 20 opened in the detection box 6. A range control plate 19 is slidably installed in the detection box 6, and a first distance measuring instrument 18 for measuring the distance between the range control plate 19 and the bottom of the rectangular groove 20 is also provided in the detection box 6; And a conversion component for driving the range control plate 19 to move in the rectangular groove 20; The first distance measuring instrument 18 is an infrared distance measuring instrument; The conversion component includes: Two conversion handles 24. Both of the two conversion handles 24 are rotatably installed in the detection box 6 through a third rotating shaft 14, and a first connecting shaft 25 is fixedly installed between the two conversion handles 24; A connecting block 15, and the connecting block 15 is rotatably installed on the first connecting shaft 25; A guiding groove 22 opened in the detection box 6. An adjusting block 21 is slidably installed in the guiding groove 22, and a third supporting shaft 31 is rotatably installed on the adjusting block 21; A driving rod 16. One end of the driving rod 16 is rotatably connected to a first supporting shaft 26, the other end of the driving rod 16 is fixedly installed with a second connecting shaft 27, and the second connecting shaft 27 is rotatably connected to the end of the connecting block 15 away from the first connecting shaft 25; An adjusting rod 17. One end of the adjusting rod 17 is rotatably connected to the third supporting shaft 31, and the other end of the adjusting rod 17 is rotatably connected to the second connecting shaft 27; And a precision adjusting component for driving the adjusting block 21 to move in the guiding groove 22; The guiding groove 22 is of an arc-shaped structure; The precision adjusting component includes: A second supporting shaft 29 rotatably installed in the detection box 6. An L-shaped supporting seat 28 is fixedly installed on the second supporting shaft 29; And a threaded rod 30 rotatably installed on the L-shaped supporting seat 28. A motor 23 for driving the threaded rod 30 to rotate is also provided on the L-shaped supporting seat 28. An internal threaded hole for threadedly connecting with the threaded rod 30 is opened on the third supporting shaft 31; The driving component includes: A cross plate 11 fixedly installed on the outside of the detection box 6. A first rotating shaft 8 is rotatably installed on the cross plate 11, and a driving gear 7 is fixedly installed on the first rotating shaft 8. A rack 4 meshing with the driving gear 7 is provided on the guiding strip 1; and a second rotating shaft 13 rotatably mounted on the side wall of the detection box 6, and the second rotating shaft 13 is connected to the first rotating shaft 8 and the second rotating shaft 13 is connected to the third rotating shaft 14 through a gear set 12; a waterproof structure is provided between the second rotating shaft 13 and the detection box 6, and the waterproof structure adopts a sealing ring, which is not specifically limited here, and the gear set 12 is two sets of meshing bevel gears.
[0033] In this embodiment, the detection box 6 can drive the driving gear 7 to rotate by means of moving in the length direction of the guide bar 1. Through the cooperative setting of the driving gear 7, the first rotating shaft 8, the gear set 12 and the second rotating shaft 13, the third rotating shaft 14 can be driven to rotate. The third rotating shaft 14 can drive the conversion handle 24 to rotate. The conversion handle 24 can drive the connecting block 15 to push or pull the driving rod 16 to move up or down by means of forward or reverse rotation and in cooperation with the limiting action of the adjusting rod 17. Thus, the range control plate 19 can be driven by the first support shaft 26 to move in the rectangular groove 20. The motor 23 can drive the threaded rod 30 to rotate, thereby driving the third support shaft 31 to move. The third support shaft 31 can drive the adjusting block 21 to move in the guide groove 22, so as to adjust the position of the end of the adjusting rod 17, making the rotation center point of the adjusting rod 17 move downward (i.e., the third support shaft 31 moves downward). When the motion states of the conversion handle 24 and the connecting block 15 remain unchanged, the highest point position of the end of the adjusting rod 17 far from the third support shaft 31 can be pushed to move 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 first distance measuring instrument 18, denoted 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 as the initial value, denoted as h. When the buoyancy member 9 and the detection box 6 float up and down with the waves, the driving assembly can drive the wave induction type control assembly to work, and then H changes. When the difference between H and h is within a predetermined range, the second distance measuring instrument 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, so as to realize the accuracy adjustment, further improve the applicable range, and improve the measurement accuracy.
