[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0028] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0029] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0030] Most of the existing oil spill alarm buoy devices use ultraviolet fluorescence active detection measurement technology and oil film passive detection technology at the terminal, which have high sensitivity, accurate measurement and low false alarm rate. At the same time, an oil-in-water monitor can be installed to monitor the background value of oil content in the water body. The oil spill detector at the terminal of the automatic control system monitors the oil spill in the set water area in real time. When an oil film is found, a command signal is sent to the alarm device to activate the alarm.

[0031] In the related art, the buoy structure is connected between the upper shell and the lower shell only by fixing bolts. However, the humidity on the sea surface is relatively high, and the bolts and other connecting components are exposed to the outside for a long time, which may cause rust and other phenomena, which is not conducive to long-term use and has certain limitations.

[0032] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides an oil spill monitoring and alarm device. After the oil spill alarm buoy device is installed, the bolt 22 is protected by adding a protective shell 25 to prevent the bolt from rusting due to being in a humid environment for a long time, thereby improving the service life of the oil spill alarm buoy device.

[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Combination Figure 1-Figure 4 , an embodiment of the present application provides an oil spill monitoring and alarm device, including a shell assembly 1; the shell assembly 1 includes: an upper shell 11, on which an upper fixing ring 12 is arranged; a lower fixing ring 13, arranged on the upper fixing ring 12; a lower shell 14, arranged on the lower fixing ring 13; a sealing assembly 2 is provided on the upper fixing ring 12; the sealing assembly 2 includes: a threaded hole 21, which is opened on the upper fixing ring 12; and partially opened on the lower fixing ring 13; a bolt 22, which is arranged on the threaded hole 21; a spring 23, which is arranged on the lower fixing ring 13; a limit block 24, which is arranged on the spring 23; a protective shell 25; which is arranged on the upper fixing ring 12; a groove 26, which is arranged on the protective shell 25; a buckle 27, which is arranged on the protective shell 25.

[0035] After we have installed the oil spill alarm buoy device, we install the protective shell 25 on the upper fixing ring 12 by aligning the groove 26 with the bolt 22. Then, by pressing the limit block 24, the limit block 24 pushes the spring 23 to shrink the spring 23. When the spring 23 shrinks to a certain position, the buckle 27 can be placed and the limit block 24 is aligned with the hollow part of the buckle 27. Then, the limit block 24 is released, and the spring 23 pops out, giving the limit block 24 a force to fix the limit block 24 with the buckle 27, so that the groove 26 on the protective shell 25 covers the bolt 22 to protect the bolt 22. At the same time, when we need to remove the protective shell 25, we push the limit block 24 so that the limit block 24 pushes the spring 23 to shrink the spring 23. When the spring 23 shrinks to a certain position, the fixation of the limit block 24 and the buckle 27 can be cancelled. Then, the protective shell 25 is taken out to complete the disassembly of the protective shell 25.

[0036] In some embodiments, a plurality of threaded holes 21 are provided to make the fixed connection more stable.

[0037] In some embodiments, a sealing ring is provided on the upper fixing ring 12 to increase the sealing performance and prevent water vapor from entering the housing.

[0038] In some embodiments, the spring 23 is a compression spring for greater stability.

[0039] In some embodiments, a handle is provided on the limit block 24 to make pushing the limit block 24 simpler and more convenient.

[0040] In some embodiments, the groove 26 is circular and can accommodate a polygonal bolt 22 of any angle.

[0041] In some embodiments, an auxiliary component 3 is provided on the upper fixing ring 12 ; the auxiliary component 3 includes a tooth plate 31 provided on the upper fixing ring 12 ; and a tooth groove 32 provided on the lower fixing ring 13 .

[0042] When installing the oil spill alarm buoy device, the tooth plate 31 can be aligned with the tooth groove 32 for pre-fixation, and the threaded hole 21 can be aligned in advance, so that the installation of the bolt 22 is simpler and more convenient.

[0043] In some embodiments, the tooth plate 31 is provided with an arc surface to make the installation of the tooth groove 32 more precise.

[0044] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.
