Description

Technical Field

[0001] This invention relates to the field of ship hull observation devices, and in particular to a ship hull observation device. Background Technology

[0002] During ship operation, observing the hull plating is quite difficult. It generally involves two parts: above and below the waterline. Above the waterline, the main focus is on observing for damage from impacts and collisions. Below the waterline, the main focus is on observing underwater components such as propellers, rudder blades, sea valves, zinc blocks, etc., which may be entangled in unidentified parts. Sometimes, the hull's waterline markings, paint damage to the plating, impact damage to the plating, and the growth of marine life are also observed.

[0003] The current equipment is rather limited; it can only be used to observe the water gauge line or the condition of the ship's outer plating below the waterline, and cannot simultaneously observe the ship's outer plating above the waterline. Summary of the Invention

[0004] The technical problem that this invention aims to solve is that existing devices can only observe the water gauge line or the condition of the ship's outer deck below the waterline, and cannot simultaneously observe the ship's outer deck above the waterline.

[0011] Preferably, the mounting bracket further includes a mounting cylinder, a connecting bolt, and a connecting nut. The mounting cylinder is vertically connected to the outer wall of the mounting ring near the square mounting frame. The mounting cylinder has a first through hole penetrating its side wall. The telescopic rod assembly has a second through hole corresponding to the first through hole. One end of the telescopic rod assembly is inserted into the mounting cylinder. The connecting bolt passes through the first through hole and the second through hole in sequence and is threaded to the connecting nut.

[0012] Preferably, the delivery assembly further includes a pulley for suspending the umbilical cable, the pulley being rotatably connected to the first protruding end.

[0013] Preferably, the inflatable component has an inflation port, and the inflatable component has an inflation nozzle for sealing or opening the inflation port.

[0014] Preferably, the display screen is mounted on the bracket.

[0015] Preferably, the bracket includes a horizontal shaft, a base frame, two diagonal braces, two vertical poles, and several clamping assemblies. The clamping assemblies are installed at the bottom of the base frame and are used to fix the bracket to the hull. The vertical poles are vertically arranged and connect the horizontal shaft to the base frame. The wire feeding winch is rotatably connected to the horizontal shaft. The diagonal braces connect the horizontal shaft to the base frame. The two diagonal braces are arranged at an angle, and the ends of the two diagonal braces away from the base frame extend and connect to form the first protruding end.

[0016] Preferably, each of the clamping assemblies includes a downward-opening U-shaped clamp and two clamping bolts. The two opposite sidewalls of the U-shaped clamp are provided with threaded holes, and the clamping bolts pass through the threaded holes one by one and are threadedly connected to the threaded holes.

[0017] Preferably, the number of clamping assemblies is four, with two clamping assemblies correspondingly disposed at the bottom of the base frame away from the upright, and two clamping assemblies correspondingly disposed at the bottom of the base frame away from the inclined rod.

[0020] The present invention provides a ship's outer plating observation device, which, compared with the prior art, has the following advantages:

[0021] By setting up an observation component, a deployment component, and a telescopic pole component, the observation component includes a camera, an inflatable component, and a mounting frame. When observing the hull above the waterline, the telescopic pole component is connected to the mounting frame. Workers can then hold the telescopic pole component or use other tools to clamp it and control the camera to move along the hull to collect the required image information. When observing the waterline, workers first inflate the inflatable component, then use the deployment component to lower the observation component to the water surface. The controller then adjusts the two propellers to align the camera with the waterline and take a picture. When observing the hull below the waterline, workers inflate the inflatable component with a small amount of gas, then use the deployment component to deploy the observation component into the water. The controller then adjusts the two propellers to align the camera with the hull and collect the required image information. Therefore, this hull observation device allows for convenient selection of either the deployment component or the telescopic pole component to observe the hull above and below the waterline, as well as the waterline.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] like Figures 1 to 6As shown, a preferred embodiment of the present invention provides a ship's outer plating observation device, comprising:

[0033] Observation component 1 includes a display screen 11, an umbilical cable 12, a controller, a mounting frame 13, and a camera 14, a battery, an inflation component 15, and two propeller thrusters 16 mounted on the mounting frame 13. The propeller thrusters 16 are preferably four-bladed propellers. The umbilical cable 12 includes a signal line connected to the camera 14 and a control line connected to the propeller thrusters 16. The controller is connected to the control line at one end away from the propeller thrusters 16. The display screen 11 is connected to the signal line at one end away from the camera 14. The battery is used to power the camera 14 and the propeller thrusters 16. The two propeller thrusters 16 are mounted on the left and right sides of the mounting frame 13.

[0034] The deployment assembly 2 includes a support 21, a wire-laying winch 22 for winding the umbilical cable 12, and a handle 23 for rotating the wire-laying winch 22. The wire-laying winch 22 is rotatably connected to the support 21. The support 21 is detachably mounted to the hull and has a first protruding end 214 protruding from the outside of the hull for suspending the umbilical cable 12.

[0035] Telescopic rod assembly 3 is telescopic and detachably connected to mounting bracket 13.

[0036] The ship's outer deck observation device based on the above embodiments comprises an observation component 1, a deployment component 2, and a telescopic rod component 3. The observation component 1 includes a camera 14, an inflatable component 15, and a mounting frame 13. When it is necessary to observe the ship's outer deck above the waterline, the telescopic rod component 3 is connected to the mounting frame 13. The operator can hold the telescopic rod component 3 or use other tools to clamp the telescopic rod component 3 to control the camera 14 to move along the ship's outer deck and collect the required image information. When it is necessary to observe the ship's waterline, the operator first inflates the inflatable component 15, and then uses the deployment component 2 to lower the observation component 1 to the water surface. The controller controls the two propeller thrusters 16 to adjust the camera 14 to align with the waterline and take pictures. When it is necessary to observe the ship's outer deck below the waterline, the operator can inflate the inflatable component 15 with a small amount of gas, and then use the deployment component 2 to deploy the observation component 1 into the water. The operator controls the two propeller thrusters 16 to adjust the position and distance of the camera 14 relative to the ship's outer deck and collect the required image information. Therefore, the ship's outer plating observation device allows for convenient selection of either the deployment component 2 or the telescopic rod component 3 for the observation component 1, enabling observation of both the ship's outer plating above and below the waterline, as well as the water gauge markings.

[0037] In some preferred embodiments, the mounting frame 13 includes a square mounting frame 131, two mounting rings 132, four rollers 133, a plurality of first connecting rods 134, and a plurality of second connecting rods 135. The first connecting rods 134 are used to connect the square mounting frame 131 to one mounting ring 132, and the second connecting rods 135 are used to connect the two mounting rings 132. The side length of the square mounting frame 131 is greater than the diameter of the mounting ring 132. The square mounting frame 131 and the two mounting rings 132 are coaxial and spaced apart. The square mounting frame 131 is enclosed by four shafts 1311 connected end to end. Each roller 133 is rotatably mounted on each shaft 1311 in a corresponding manner. The camera 14 is connected to and passes through the mounting ring 132 near the square mounting frame 131. The propeller thruster 16 and the inflator 15 are connected to the second connecting rods 135. By setting up a mounting frame 13 including a square mounting frame 131 and two mounting rings 132, the roller 133 is rotatably mounted on the shaft 1311 of the square mounting frame 131, and the side length of the square mounting frame 131 is greater than the diameter of the mounting rings 132. When the staff holds the telescopic rod assembly 3 to observe the ship's outer plate above the waterline, the square mounting frame 131 moves attached to the ship's outer plate, so that the camera 14 faces the ship's outer plate and maintains a constant distance from the ship's outer plate. The roller 133 is set on four shafts 1311, so it can not only play a guiding role to keep the camera 14 moving in a straight line in a certain direction, but also reduce the friction between the square mounting frame 131 and the ship's outer plate.

[0038] Preferably, the second connecting rod 135 located on the top side of the mounting frame 13 has a threading hole for the umbilical cable 12 to pass through. The threading hole can limit the umbilical cable 12, and the passage of the umbilical cable 12 through the second connecting rod 135 located on the top side of the mounting frame 13 can ensure that the observation component 1 is vertical and not tilted when it is deployed.

[0039] Preferably, the mounting frame 13 further includes a mounting cylinder 136, a connecting bolt 137, and a connecting nut. The mounting cylinder 136 is vertically connected to the outer wall of the mounting ring 132 near the square mounting frame 131. The mounting cylinder 136 has a first through hole penetrating its side wall. The telescopic rod assembly 3 has a second through hole corresponding to the first through hole. One end of the telescopic rod assembly 3 is inserted into the mounting cylinder 136. The connecting bolt 137 passes through the first through hole and the second through hole in sequence and is threaded to the connecting nut. By setting the mounting cylinder 136 vertically connected to the outer wall of the mounting ring 132, the camera 14 can be directly facing the outer plate of the ship when observing it above the waterline using the telescopic rod assembly 3. Furthermore, since the selected mounting ring 132 is close to the square mounting frame 131, it helps the observation assembly 1 to maintain balance. The telescopic rod assembly 3 and the mounting frame 13 can be assembled and disassembled simply by rotating the connecting nut.

[0040] Preferably, the delivery assembly 2 further includes a pulley 24 for suspending the umbilical cable 12, the pulley 24 being rotatably connected to the first protruding end 214. By providing the pulley 24 at the first protruding end 214, the pulley 24 rotates when suspending the umbilical cable 12, reducing the frictional force on the umbilical cable 12.

[0041] Preferably, the inflator 15 has an inflation port and an inflation nozzle 151 for sealing or opening the inflation port. Before installing the observation assembly 1 onto the telescopic rod assembly 3 or deploying it using the deployment assembly 2, the operator can inflate the inflator 15 with an appropriate amount of gas.

[0042] Preferably, the display screen 11 is mounted on the bracket 21 of the delivery component 2 for easy real-time observation by personnel.

[0043] Preferably, the support 21 includes a horizontal shaft 211, a base frame 212, two diagonal rods 213, two vertical rods 215, and several clamping assemblies 216. The clamping assemblies 216 are installed at the bottom of the base frame 212 and are used to fix the support 21 to the hull. For example, the clamping assemblies 216 can be clamped to the side plate of the hull. The two vertical rods 215 are vertically spaced and connect the horizontal shaft 211 and the base frame 212. The wire-laying winch 22 is rotatably connected to the horizontal shaft 211. The diagonal rods 213 connect the horizontal shaft 211 and the base frame 212. The two diagonal rods 213 are set at an angle, and the ends of the two diagonal rods 213 that are away from the base frame 212 extend and connect to form a first protruding end 214. By setting several clamping assemblies 216, the support 21 can be stably and detachably installed to the hull. Since the two diagonal rods 213 are set at an angle and the ends that are away from the base frame 212 extend and connect, they can protrude upwards to the outside of the hull, which is convenient for deploying the observation component 1.

[0044] Furthermore, each clamping assembly 216 includes a downward-opening U-shaped clamp 2161 and two clamping bolts 2162. The two opposite sidewalls of the U-shaped clamp 2161 are provided with threaded holes, and the clamping bolts 2162 pass through the threaded holes one-to-one and are threadedly connected to them. When the clamping assembly 216 is used for clamping, the clamped part is located within the opening of the U-shaped clamp 2161, and the two clamping bolts 2162 are tightened into the opening to abut against the clamped part, thus achieving clamping.

[0045] Preferably, there are four clamping assemblies 216. Two clamping assemblies 216 are arranged one-to-one at the bottom of the base frame 212 away from the bottom of the upright 215, and two clamping assemblies 216 are arranged one-to-one at the bottom of the base frame 212 away from the bottom of the diagonal bar 213. Using at least four clamping assemblies and arranging them below the ends of the upright and diagonal bars can securely install the bracket to the hull.

[0046] Preferably, the display screen 11 is located between two diagonal rods 213. The two adjacent side walls of the display screen 11 are respectively connected to the base frame 212 and a diagonal rod 213. The display screen 11 is tilted with the diagonal rod 213 to facilitate visual observation by personnel.

[0047] Preferably, the telescopic rod assembly 3 includes an inner rod 31, an outer cylinder 32, a locking bolt 33, and a locking nut 34. One end of the inner rod 31 is detachably connected to the mounting bracket 13, and the other end of the inner rod 31 is slidably disposed inside the outer cylinder 32. A locking hole is provided on the side wall of the outer cylinder 32. The locking nut 34 is welded to the outside of the outer cylinder 32 and corresponds to the locking hole. The locking bolt 33 is threadedly connected to the locking nut 34. By rotating the locking bolt 33, the inner rod 31 can be loosened or locked, adjusting and fixing its position in the outer cylinder 32, thereby realizing the telescopic extension and retraction of the telescopic rod assembly 3. The second through hole is preferably located near the end of the inner rod 31 facing away from the outer cylinder 32 to facilitate the connection between the telescopic rod assembly 3 and the mounting bracket 13.

[0048] The working process of this invention is as follows:

[0049] (1) When observing the ship's outer plating above the waterline, first determine the observation position, install the observation component 1 to one end of the telescopic rod component 3, adjust the telescopic rod component 3 to the required length, tie the umbilical cable to the telescopic rod component 3, and then move the observation component 1 along the ship's outer plating to the corresponding position to collect images. After completion, retract the observation component 1.

[0050] (2) When observing the water level mark, first determine the observation position, fix the deployment component 2 at the corresponding side plate and railing, fill the inflation component 15 with enough gas to make the observation component 1 float on the water surface, turn the handle 23 to make the line-laying winch 22 rotate, and the umbilical cable 12 lowers the observation component 1 to the water surface. While observing the real-time image displayed on the display screen 11, control the two propeller thrusters 16 through the controller. If only the right propeller thruster 16 is activated, the observation component 1 will rotate counterclockwise. If only the left propeller thruster 16 is activated, the observation component 1 will rotate clockwise. When the two propeller thrusters 16 rotate synchronously, they will push the observation component 1 forward. In this way, adjust the field of view of the camera 14 to be able to observe the water level mark well and collect images. After completion, retract the observation component 1.

[0051] (3) When observing the ship's outer deck below the waterline, first determine the observation position, fix the deployment component 2 at the corresponding side plate and railing, fill the inflation component 15 with an appropriate amount of gas, turn the handle 23 to make the casting winch 22 rotate, and the umbilical cable 12 lowers the observation component 1 underwater. While observing the real-time image displayed on the display screen 11, control the two propeller thrusters 16 through the controller. If only the right propeller thruster 16 is activated, the observation component 1 will rotate counterclockwise. If only the left propeller thruster 16 is activated, the observation component 1 will rotate clockwise. When the two propeller thrusters 16 rotate synchronously, they will push the observation component 1 forward, thereby adjusting the field of view of the camera 14 to collect images of the ship's outer deck below the waterline. After completion, the observation component 1 is retrieved.

[0052] In summary, this invention provides a ship hull observation device. It comprises an observation component, a deployment component, and a telescopic rod component. When observing the hull above the waterline, the telescopic rod component is connected to the mounting frame. Workers can hold the telescopic rod component or use other tools to clamp it, controlling the camera to move along the hull and collect the required image information. When observing the waterline, workers first inflate the inflatable component, then use the deployment component to lower the observation component to the water surface. The controller then controls the two propellers to adjust the camera's position relative to the waterline for image capture. When observing the hull below the waterline, workers inflate the inflatable component with a small amount of gas, then use the deployment component to deploy the observation component into the water. The controller then controls the two propellers to adjust the camera's position and distance relative to the hull and collect the required image information. Therefore, this ship hull observation device allows for convenient selection of either the deployment component or the telescopic rod component to simultaneously observe the hull above and below the waterline, as well as the waterline.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
