[0022] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.

[0023] As attached Figure 1 , Attachment Figure 2 As shown, the utility model is a lighting device for the cargo hold of an engineering vessel, wherein the vessel's cabin includes a bulkhead 1, an opening 2 is provided on the bulkhead 1, a cavity 3 extending to the outside of the bulkhead 1 is provided at the position of the opening 2, a bracket 4 is installed inside the cavity 3, a lighting fixture 5 is installed on the bracket 4, and a plurality of protective members 6 are provided at the position of the opening 2. The above structure proposes an improved technical solution to the deficiencies in the prior art. The actual requirements for lighting in the cargo hold of an engineering vessel are: the installation of the cargo hold lighting must not affect the structural strength of the hull; during loading operations inside the cargo hold, the cargo hold requires sufficient illumination, and blind spots in the lighting must be avoided as much as possible; the installation of the cargo hold lighting inside the cargo hold must not affect the loading and unloading process, that is, it must not protrude from the cargo hold bulkhead as much as possible; the loading and unloading operations of grabs or forklifts inside the cargo hold require consideration of the mechanical protection of the lighting fixtures; the lighting fixtures must be convenient for future maintenance and inspection after installation; and the openings in the cargo hold structure must not affect the watertight integrity of the cargo hold. In response to the above needs, when the structure is set up, the inside of the ship's cabin is the cargo hold, which is used to place cargo, and the cargo hold requires lighting of sufficient brightness. For this purpose, the lighting device is improved, and an opening 2 is set on the bulkhead 1. A cavity 3 extending to the outside of the bulkhead 1 is set at the position of the opening 2. A bracket 4 is installed inside the cavity 3, and a lighting fixture 5 is installed on the bracket 4. Multiple protective members 6 are set at the position of the opening 2. In this way, as long as the lighting fixture is turned on, the lighting fixture 5 emits bright light, which shines into the cargo hold from the opening 2 and reliably meets the lighting needs. The cavity extends outward and is opposite to the opening, that is, the lighting of the lighting fixture is equivalent to lighting inside the cabin, with good lighting effect, while not occupying space inside the cabin. The setting of the multiple protective members 6 protects the lighting fixture 5 to prevent cargo or tools from penetrating through the opening and damaging the lighting fixture 5 during operations inside the cabin. The cargo hold lighting device for engineering ships described in the utility model has a simple structure and can effectively meet the lighting needs inside the cargo hold. It has a brighter lighting effect and a smaller blind spot. It does not occupy space inside the hold and protects the lighting fixtures from being easily damaged. It is easy to replace or maintain, thus meeting the lighting needs of ships.

[0024] The cavity 3 comprises a main body connected to the exterior of the bulkhead 1. The rear portion of the main body is open, connected to a rear closure panel 7. This structure creates a closed cavity, located entirely outside the bulkhead and not protruding from the cargo hold. The provision of the closure panel 7 ensures reliable installation and easy removal. Once installed, it effectively connects to the cavity, providing a good seal. It can be removed during disassembly, facilitating maintenance or replacement of lighting fixtures.

[0025] The rear opening is provided with a rear connection panel 8, which is provided with multiple screw holes. Each bolt passes through a through-hole in the rear closure panel 7 and connects to a screw hole. This structure allows for easy removal of the rear closure panel 7 as needed, while also ensuring secure connection. A sealing gasket is provided between the rear closure panel 7 and the rear connection panel 8 to ensure a reliable seal between the rear connection panel 8 and the rear closure panel 7.

[0026] The multi-layer protection member 6 is a rod structure, and the multi-layer protection member 6 is arranged in parallel with a gap. The above structure and the arrangement of the multi-layer protection member play a protective role at the opening, which can effectively avoid mechanical damage without affecting the reliable light projection of the lighting fixture into the cargo hold.

[0027] The bulkhead 1 is externally provided with a first vertical beam 9 and a second vertical beam 10. The cavity is arranged between the first and second vertical beams 9, 10, and the cavity connects the first and second vertical beams 9, 10. Each protective member 6 is connected to the first vertical beam 9 at one end, and to the second vertical beam 10 at the other end. In this structure, the first and second vertical beams 9, 10 can be welded to the exterior of the bulkhead 1. The parallel arrangement of the first and second vertical beams 9, 10 ensures a reliable connection to the cavity 3.

[0028] The lighting fixture 5 is hingedly connected to the bracket 4. Bracket 4 is provided with a positioning pin, and the lighting fixture 5 is provided with multiple positioning holes. This structure allows the lighting fixture's angle to be adjusted as needed. To adjust the angle, the positioning pin is inserted into the positioning hole to secure the lighting fixture. Inserting the positioning pin into different positioning holes allows the lighting fixture's illumination angle to be adjusted to suit different needs.

[0029] One end of each guard 6 is movably mounted on the first vertical beam 9, and the other end is movably mounted on the second vertical beam 10. With this structure, when adjusting the angle of the lighting fixture, the operator does not need to open the rear sealing plate 7. Instead, they simply pull the guard 6, allowing them to reach into the cavity and adjust the lighting fixture's angle. After adjustment, the guard 6 is simply reset.

[0030] A handle 11 is provided on the rear closing plate 7. The handle is convenient for hand-held installation or removal of the rear closing plate.

[0031] The cargo hold lighting device for an engineering vessel described in the present invention is for placing cargo in the cargo hold of the vessel. The cargo hold requires lighting of sufficient brightness, so the lighting device is improved. An opening 2 is provided on the bulkhead 1, and a cavity 3 extending to the outside of the bulkhead 1 is provided at the position of the opening 2. A bracket 4 is installed inside the cavity 3, and a lighting fixture 5 is installed on the bracket 4. Multiple protective members 6 are provided at the position of the opening 2. In this way, as long as the lighting fixture is turned on, the lighting fixture 5 emits bright light, which illuminates the cargo hold from the opening 2 and reliably meets the lighting needs. The cavity extends outward and is opposite to the opening, that is, the lighting of the lighting fixture is equivalent to lighting inside the cabin, with good lighting effect, while not occupying space inside the cabin. The provision of multiple protective members 6 protects the lighting fixture 5, preventing cargo or tools from penetrating through the opening and damaging the lighting fixture 5 during operations inside the cabin.

[0032] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
