Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ship navigation safety equipment, and in particular to an integrated device of pilot sunshade and navigation signal light mast. Background Technology
[0002] With the advancement of ship technology and increasingly stringent environmental protection requirements, many ships have begun to be equipped with wind-assisted propulsion systems, such as rotary sails (also known as rotor sails), airfoil sails, and suction sails, to utilize wind energy to reduce fuel consumption and carbon emissions. However, the addition of sails often results in the obstruction of the arc angle of the navigation signal lights on the mainmast at the top of the compass deck, failing to meet the installation requirements of the 1972 International Regulations for Preventing Collisions at Sea (ICCAL) for the horizontal arc of all-around lights. The ICAL stipulates that all-around lights should be installed in a position where they are not obstructed by the mast, top mast, or other structures at an arc angle greater than 6 degrees.
[0003] If a single all-around light is insufficient, two all-around lights must be used, either fixed in a suitable position or shielded with a baffle to ensure that they appear as a single light as possible from a distance of 1 nautical mile. This shielding issue not only affects the safety of navigation but also increases the compliance risks of ships navigating in specific waters.
[0004] To address these issues, those skilled in the art have proposed an integrated pilot sunshade and navigation signal light mast device. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0038] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0039] Example 1
[0040] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a pilot sunshade and navigation signal light mast integrated device, which can solve the problem of light being blocked and optimize the spatial layout. It includes a bridge deck 13, which is the main support body of the device.
[0041] A light mast 1 is vertically mounted on the bridge deck 13;
[0042] Base 2, which are equidistantly distributed and installed on one side of the outer wall of the mast 1;
[0043] The all-weather lamp 3 is mounted on the base 2;
[0044] 14 bulwark is installed on the surface of the bridge deck 13 at a position that fits against the outer edge.
[0045] Columns 11, multiple columns 11 are installed on both sides of the surface of the bulwark 14 near both ends;
[0046] The awning 10 is installed on the column 11.
[0047] The sunshade 10 adopts a design that is higher at the front and lower at the rear, with a front height of 2.25 meters and a rear height of 2.10 meters. This design can effectively guide rainwater to flow backward, thereby avoiding rainwater from interfering with the pilot's forward vision and ensuring a clear and unobstructed field of vision.
[0048] Specifically, the all-around light 3 consists of two lights forming a group, and the all-around light 3 is divided into three groups. From top to bottom, the all-around light 3 is: limited draft light 1 301, limited maneuverability light 1 302, limited draft light 2 303, limited maneuverability light 2 304, limited draft light 305, and limited maneuverability light 306.
[0049] The three sets of all-around lights 3 installed on the mast 1, taking the double-layered lights as an example, can be flexibly combined for display: the uppermost red light at the highest point (limited to draft lights / loss of control lights) is limited to draft light one 301, and the uppermost red light at the middle point (limited to draft lights / loss of control lights) is limited to draft light two 303. This can be used as a display for a vessel that has lost control: two vertical all-around red lights in the most visible position;
[0050] The highest red light (limited to draft lights / loss of control lights), together with the middle red light (limited to draft lights / loss of control lights) and the lower red light (limited to draft lights), can be used as a display for ships limited to draft. Three all-around red lights can be displayed vertically in the most visible position.
[0051] The lowermost red light (restricted maneuverability light), the lower middle white light (restricted maneuverability light), and the lower bottom red light (restricted maneuverability light) can be used to indicate that a vessel with restricted maneuverability should display: three vertical all-around lights in the most visible position, with the uppermost and lowermost lights red and the middle light white.
[0052] In use, the three sets of all-around lights 3 on the navigation signal mast 1 are flexibly combined to display different ship statuses according to the display requirements of the International Regulations for Preventing Collisions at Sea 1972, and the spacing between the bases 2 is 2 meters.
[0053] Example 2
[0054] Reference Figures 1 to 5This is the second embodiment of the present invention. Unlike the previous embodiment, a straight ladder 12 is vertically installed on the surface of the driving deck 13, and one end of the straight ladder 12 is installed on the outer wall of one side of the sunshade 10.
[0055] Specifically, a fence 9 is provided at the position where the surface of the awning 10 is in contact with the outer edge, and an entrance is provided above the fence 9 near the top of the straight ladder 12.
[0056] Furthermore, multiple chains 8 are installed near the entrance of the fence 9.
[0057] Among them, the awning 10 has handrails 7 installed on both sides of the surface near the end of the chain 8.
[0058] Among them, the outer side of the surface of the sunshade 10 near the light mast 1 is equipped with a diagonal brace 4, and the other end of the diagonal brace 4 is installed on the outer wall of the light mast 1.
[0059] In use, the pilot's sunshade 10 is installed on the bridge bulwark 14 on the port and starboard sides of the bridge deck 13 via four pillars 11. It adopts a design that is higher at the front and lower at the rear, with a front height of 2.25 meters and a rear height of 2.1 meters. It can effectively guide rainwater to flow backward to avoid interfering with the pilot's forward vision, and also provide the pilot with a place for sunshade and rain shelter, meeting the requirements of the Panama Canal Authority for the pilot's work platform. A straight ladder 12 is installed on its side, and a handrail 7, chain 8 and railing 9 are provided at the top edge to facilitate personnel to go up and down the platform for maintenance and ensure operational safety.
[0060] Example 3
[0061] Reference Figures 1 to 5 This is the third embodiment of the present invention. Unlike the previous embodiment, multiple pedals 5 are installed at equal intervals on one side of the outer wall of the mast 1 near the top of the sunshade 10.
[0062] Specifically, a protective ring 6 is installed on the outer wall of the top of the light mast 1 near the step 5.
[0063] When in use, steps 5 and guardrails 6 are provided from the top of the pilot's sunshade 10 to the top of the navigation signal light mast 1, providing gripping points for personnel to maintain the all-weather light 3 and increasing safety.
[0064] The working principle and usage process are as follows:
[0065] When a vessel is navigating in specific waters, the pilot can work under the pilot's sunshade 10. Its forward-high, aft-low design ensures a clear and unobstructed field of vision for the pilot. If maintenance is required on the all-around lights 3 on the navigation signal mast 1, maintenance personnel can ascend and descend the sunshade 10 via the ladder 12 and reach the corresponding position on the mast 1 using the footboard 5 and guardrail 6. The three sets of all-around lights 3 on the mast 1 can be flexibly combined to display information according to requirements, for example:
[0066] When a vessel is out of control, two vertically illuminating red lights can be installed and displayed at the highest point (upper red light 301) and the middle point (upper red light 303).
[0067] When the vessel is limited to a certain draft, three all-around red lights may be installed and displayed vertically at the highest point (upper red light 301), the middle point (upper red light 303), and the lower point (upper red light 305).
[0068] When a vessel's maneuverability is restricted (not for vessels engaged in mine clearance operations), three vertical all-around lights may be installed and displayed at the following locations: the highest red light 302, the middle white light 304, and the lowest red light 306. The highest and lowest lights are red, and the middle one is white.
[0069] The term "out-of-control vessel" refers to a vessel that, due to some unusual circumstance, is unable to maneuver as required and therefore cannot give way to other vessels.
[0070] The term "vessel with limited maneuverability" refers to a vessel whose maneuverability is limited by the nature of its work, thus preventing it from giving way to other vessels.
[0071] The term "draft-limited vessel" refers to a motorized vessel whose ability to depart from its course is severely restricted due to the relationship between its draft and the available depth and width of the navigable waters.
[0072] This integrated device innovatively combines the pilot's sunshade with the navigation signal light mast, solving the problem of sails obstructing navigation signals. It achieves a multifunctional configuration, optimizes the spatial layout of the ship's superstructure, improves the safety, practicality, and economy of the ship when navigating in specific waters, and reduces maintenance costs and time, thereby improving the ship's operational efficiency.
[0073] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
[0074] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
