Abstract
Description
Technical Field
[0001] This utility model relates to an anchor observation device, particularly an anchor observation device for a very large container ship, and belongs to the field of shipbuilding technology. Background Technology
[0002] In recent years, an increasing number of ultra-large container ships with a capacity exceeding 20,000 TEU have been designed and built. The adoption of new regulations for ultra-large container ships has led to an increase in the number of cable winches. As a result, the exposed deck area at the bow has increased, causing a significant outward flare at the bow of large container ships, making it more difficult for crew members to observe the anchor deployment and retrieval from the bulwark.
[0003] There are generally two methods for observing anchors on container ships. One is to have a hole drilled in the bulwark, requiring crew members to lie prone at a significant angle, or even stick their heads out of the bulwark, to observe the anchor. The other is to have a platform set up in a suitable location, extending from the hull plating manually or hydraulically, requiring crew members to observe the anchor from the platform. The first and second methods are inconvenient to operate, especially when the anchor is stored in an anchorage hole, the observation effect is far from ideal, and there are potential hazards. The latter method is particularly costly, and it is also unsafe for crew members to stand on the overboard platform during rough seas. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an anchor observation device for ultra-large container ships that is simple to operate, safe, and low in cost.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An anchor observation device for an ultra-large container ship includes a bracket, a camera, a limiting plate, and a monitor. Observation ports are opened on the bulwark. One end of the bracket is hinged to the limiting plate, and the camera is fixed to the other end of the bracket. Pins perpendicular to the bracket are provided on both sides of the bracket. The limiting plate is located on both sides of the bracket and is fixed to the inner wall of the bulwark inside the observation port. Arc-shaped guide grooves are opened on the limiting plates. The pins on both sides of the bracket are slidably set in the guide grooves of the limiting plates on both sides. The monitor is wirelessly connected to the camera.
[0006] Furthermore, the bracket is an L-shaped bracket.
[0007] Furthermore, the camera is positioned perpendicular to the other end of the bracket.
[0008] Furthermore, the monitor is a smartphone or tablet, and the camera is wirelessly connected to the monitor via Bluetooth or WIFI to upload the real-time captured video to the monitor.
[0009] Furthermore, a handle is provided on each side of the observation port. The handles are set vertically and fixed inside the observation port. The two handles are symmetrically arranged on both sides of the observation port, and the distance between the two handles matches the width of the camera.
[0010] Furthermore, the observation port is provided with an openable and closable transparent window.
[0011] Furthermore, the limiting plate adopts a fan-shaped flat plate structure, with two limiting plates vertically fixed on the inner wall of the bulwark and symmetrically arranged on both sides of the bracket.
[0012] Furthermore, the end of the pin is provided with an external thread, one end of the pin passes through the guide groove on the limiting plate, and the locking nut is sleeved on the end of the pin and threadedly connected to the pin.
[0013] Furthermore, the bulwark is located on one side of the forecastle deck, and an anchor chain cylinder is provided on the forecastle deck. The anchor chain is installed inside the anchor chain cylinder, and the anchor is fixed to the lower end of the anchor chain. An anchor platform is provided on the outer plate at the lower end of the anchor chain cylinder.
[0014] Compared with existing technologies, this utility model has the following advantages and effects: This utility model discloses an anchor observation device for ultra-large container ships. Through a flip-up camera structure, the camera extends out from the bulwark. The anchor's deployment and retrieval can be observed simply by checking a monitor wirelessly connected to the camera. This structure is simple to operate, reliable, and unaffected by wind, waves, weather, or time. It also enhances safety for crew operation and is more cost-effective compared to external platforms. Furthermore, the use of high-definition night vision cameras provides clearer and better-angled observation of the correct anchor deployment and retrieval compared to human observation. The observed video can be stored on a monitor or in the cloud for easy retrieval. Attached Figure Description

[0018] To elaborate on the technical solutions adopted by this utility model to achieve the intended technical objectives, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Furthermore, the technical means or technical features in the embodiments of this utility model can be replaced without creative effort. The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0019] like Figure 1 As shown, this utility model discloses an anchor observation device for a super-large container ship, comprising a bracket 1, a camera 2, a limiting plate 3, and a monitor 4. An observation port 6 is provided on the bulwark 5. One end of the bracket 1 is hinged to the limiting plate 3. Due to the need to maintain the structural integrity of the bulwark 5, the bracket 1 cannot be directly hinged to the bulwark 5. Therefore, the bracket 1 is directly hinged to the limiting plates 3 on both sides. If only a single-sided limiting plate structure is used, a hinge lug can be added to the other side. The camera 2 is fixed to the other end of the bracket 1. Pins 7 perpendicular to the bracket 1 are provided on both sides of the bracket 1. The limiting plates 3 are provided on both sides of the bracket 1 and fixed to the inner wall of the bulwark 5 inside the observation port 6. Arc-shaped guide grooves 8 are provided on the limiting plates 3. The pins 7 on both sides of the bracket 1 are slidably disposed within the guide grooves 8 of the limiting plates 3. The monitor 4 is wirelessly connected to the camera 2.
[0020] The bracket 1 is an L-shaped bracket with the pointed end of the L-shape facing upwards. When the bracket 1 is flipped inwards along the hinge axis to the innermost end of the guide groove 8, the camera 2 at the other end of the bracket 1 is located inside the hinge axis. At this time, the camera 2 uses its own weight to position the bracket at the innermost end of the guide groove 8. When the bracket 1 is flipped outwards along the hinge axis to the outermost end of the guide groove 8, the camera 2 at the other end of the bracket 1 passes through the observation port 6 and flips to the outside of the bulwark 5, aligning with the anchor position. It collects real-time data on the anchor retrieval and uploads it to the monitor. The L-shaped design of the bracket 1 allows the camera 2 to flip outwards at a larger angle.
[0021] Camera 2 is positioned perpendicular to the other end of bracket 1, so that during the rotation of bracket 1, camera 2 moves approximately along the tangential direction of the rotation arc, making it easier to design the final alignment of camera 2 with the anchor position.
[0022] Monitor 4 uses a smartphone or tablet, and camera 2 connects wirelessly to monitor 4 via Bluetooth or WIFI to upload real-time video of the anchor being retrieved. This way, the crew can observe the anchor retrieval situation from the deck without having to lean out of the ship's side or stand on an external platform, ensuring the crew's safety even in windy and turbulent weather.
[0023] like Figure 3As shown, a handle 9 is installed on each side of the observation port 6. The handles 9 are vertically positioned and fixed inside the observation port 6. The two handles 9 are symmetrically arranged on both sides of the observation port 6, and the distance between the two handles 9 matches the width of the camera 2. The handle 9 structure not only prevents deck items from falling through the observation port 6, but also allows crew members on deck to hold onto the handles 9 for balance in windy and wavery weather. The observation port 6 is equipped with an openable transparent window, which can be closed when not in use to protect the camera 2.
[0024] The limiting plate 3 adopts a fan-shaped flat plate structure. Two limiting plates 3 are vertically fixed on the inner wall of the bulwark 5 and symmetrically arranged on both sides of the bracket 1. The arc of the fan-shaped surface of the fan-shaped flat plate matches the arc of the arc-shaped guide groove 8.
[0025] One end of the pin 7 has an external thread, and the other end passes through the guide groove on the limiting plate 3. A locking nut is fitted onto the end of the pin 7 and threadedly connected to it. Although the camera 2 can maintain its position by its own weight when retracted, it is prone to flipping outwards and hitting the window of the observation port 6 when the ship is rocking violently in windy and wavering weather, causing damage to the camera 2. Therefore, through the cooperation of the locking nut and the external thread structure of the pin 7, when the camera 2 is retracted, rotating the locking nut locks the pin 7 in place within the guide groove 8, thereby preventing damage to the camera 2 in windy and wavering weather.
[0026] like Figure 2 As shown, the bulwark 5 is located on one side of the forecastle deck 10. Anchor chain cylinders 11 are opened on the forecastle deck 10, and anchor chains 12 are installed inside the anchor chain cylinders 11. Anchors 13 are fixed to the lower end of the anchor chains 12. Anchor platforms 15 are installed on the outer plate 14 at the lower end of the anchor chain cylinder 11. The anchor 13 is stored using an anchor platform 15 located outside the outer plate 14, so that the anchor 13 is located outside the outer plate 14 when stored, making it easy for the camera 2 to observe.
[0027] This utility model discloses an anchor observation device for ultra-large container ships. It utilizes a flip-up camera that extends beyond the bulwark. The anchor's deployment and retrieval can be observed by monitoring a monitor wirelessly connected to the camera. This structure is simple to operate, reliable, and unaffected by wind, waves, weather, or time, making it safer for crew members. Furthermore, it is more cost-effective than external platforms. Utilizing high-definition night vision cameras, the correct deployment and retrieval of the anchor is observed more clearly and from a better angle than with the human eye. The observed video can be stored on a monitor or in the cloud for easy retrieval.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments without departing from the scope of the present utility model's technical solution, based on the technical essence of the present utility model and within the spirit and principles of the present utility model, shall still fall within the protection scope of the present utility model's technical solution.
