Description

Technical Field

[0001] The present invention relates to the technical field of ship lighting, and in particular to an integrated installation structure and an installation method of a floodlight. Background Art

[0002] As outdoor floodlights have high luminous flux and long irradiation distance, they are usually installed in open-air places such as bulwarks or outside handrail structures using floor-standing bases or wall-mounted bases.

[0003] At present, the installation method commonly used for marine floodlights is that the base is installed in an open-air layout. The base, cable entry parts of the lamp body, stuffing box, and connecting cables are all exposed outside the hull, which not only affects the beauty of the floodlight layout, but also the exposed parts will rust and age over time, and the physical and chemical properties will decay. Frequent maintenance of vulnerable parts is also required. When the wind conditions on the sea are bad, the lamp body and base are completely exposed outside the hull, which can easily cause the lamp body and base to shake. Summary of the invention

[0030] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] For example, when describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional view showing the device structure will not be partially enlarged according to the general scale, and the schematic view is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional space dimensions of length, width and depth should be included.

[0032] For ease of description, spatial relational terms such as "under", "below", "below", "below", "above", "on", etc. may be used herein to describe the relationship of one element or feature shown in the drawings to other elements or features. It will be understood that these spatial relational terms are intended to include other directions of the device in use or operation in addition to the directions depicted in the drawings. In addition, when a layer is referred to as being "between" two layers, it can be the only layer between the two layers, or there can be one or more intervening layers. As used herein, "between..." means including the end point values.

[0033] In the context of the present application, a structure in which a first feature is described as being "above" a second feature may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features are formed between the first and second features, such that the first and second features may not be in direct contact.

[0034] It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner, and therefore the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0035] like Figure 1 to Figure 2 As shown, it is an existing floodlight installation structure, wherein the base 11 is directly welded to the outside of the hull 100, and the base, lamp body, cable entry parts, stuffing box, connecting cables and other components are all exposed outside the hull, which are very prone to rust and aging, greatly affecting the service life. Therefore, it is necessary to improve the existing installation structure and transfer the components to the inside of the hull for installation so as to isolate them from the external environment and extend the life of the components.

[0036] Embodiment 1

[0037] like Figures 3 to 7As shown, this embodiment provides an integrated installation structure of a floodlight, including a window frame 21, which is welded to the opening of the hull 100. Along the thickness direction of the hull 100, the window frame 21 has a first protrusion located on the outside of the hull and a second protrusion located on the inside of the hull. The thickness of the first protrusion is 100 mm, the thickness of the second protrusion is 60 mm, and the thickness of the entire window frame is about 160 mm. The window frame 21 and the opening of the hull 100 are circumferentially welded, and both the inside and outside of the hull are circumferentially welded to ensure welding strength and sealing. It should be understood that the thickness of the first protrusion and the second protrusion is not limited to the above values, and can be flexibly adjusted according to the size of the lamp body to ensure that the lamp body does not interfere during installation and use.

[0038] Furthermore, the bottom frame of the second protruding portion is connected to the base plate 25 through an L-shaped connecting plate 23, and the L-shaped connecting plate 23 includes a first sheet and a second sheet located in the same plane and perpendicular to each other, the first sheet is fixed to the lower surface of the bottom frame of the second protruding portion, and the second sheet is fixed to the lower surface of the base plate 25. The L-shaped connecting plate 23 is connected to the bottom frame and the base plate through bolts 27, so as to facilitate disassembly and replacement. The corners of the L-shaped connecting plate 23 are provided with R60 fillets to reduce the weight of the fixed connecting plate.

[0039] The lamp body bracket 13 of the floodlight is fixed on the base plate 25. The lamp body bracket 13 is a U-shaped frame with the opening of the U-shaped frame facing upward. The lamp body 12 of the floodlight is rotatably connected to the lamp body bracket 13, so that the light source angle of the lamp body can be changed.

[0040] The width of the left and right frames of the window frame 21 from the lamp body is 130-160 mm, for example, 150 mm, and the height of the upper frame of the window frame 21 from the lamp body is 150-170 mm, for example, 160 mm.

[0041] Furthermore, the outer port cover of the window frame 21 is provided with a protective glass 22 to block the external environment.

[0042] Furthermore, a cable hole 26 is provided at the center of the base plate 25 for the cable of the lamp body to pass through. The window frame 21 is also provided with a grounding hole 28 for connecting a grounding wire.
