These multiple monitoring instruments are usually installed separately on the cargo hold deck using a one-gauge-one-base method. Specifically, when installing each monitoring instrument, a hole needs to be drilled in the cargo hold deck, and a through-hole fitting and instrument base need to be installed at the hole. Then, the monitoring instrument is installed on the instrument base.

[0003] However, the installation methods of the aforementioned monitoring devices have the following problems:

[0004] Creating multiple perforations and welding multiple instrument bases on the cargo hold deck not only increases the workload of instrument installation but also increases the risk of leaks at the welds on the cargo hold deck. It also makes it more difficult to arrange equipment and pipelines on the deck. Utility Model Content

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0022] Please refer to the attached document. Figure 1-2 This application provides a centralized liquid cargo tank monitoring device, which is installed on the perforated structure of the liquid cargo tank deck 100 to monitor data inside the liquid cargo tank, wherein the perforated structure penetrates the liquid cargo tank deck 100.

[0023] The cargo tank monitoring device includes a common base and multiple monitoring instruments. The common base includes a support pipe 210, a support pipe flange 220, and a common cover plate 230. The support pipe 210 is inserted into the perforated structure with both ends extending out of the structure. The support pipe 210 is welded to the cargo tank deck 100. The support pipe flange 220 is welded to the outer end of the support pipe 210, and there is a gap between the support pipe flange 220 and the top surface of the cargo tank deck 100. The common cover plate 230 covers the side of the support pipe flange 220 away from the support pipe 210 and is fixedly connected to the support pipe flange 220. It should be understood that the outer end of the support pipe 210 refers to the end of the support pipe 210 that is away from the inner cavity of the cargo tank when installed in the perforated structure. The common cover plate 230 has multiple mounting holes 240, and each mounting hole 240 is equipped with a monitoring instrument. The monitoring instrument installed at mounting hole 240 is connected to the interior of the liquid cargo tank through mounting hole 240 and performs data monitoring inside the liquid cargo tank.

[0024] In this embodiment, by centrally arranging multiple monitoring instruments on a common cover plate 230, and the common cover plate 230 being installed on the cargo tank deck 100 via a hole structure using a support pipe 210, it is not necessary to drill multiple perforations or weld multiple instrument bases on the cargo tank deck 100. This not only reduces the workload of installing the cargo tank monitoring device, but also reduces the risk of leakage at welded joints on the cargo tank deck 100. At the same time, it also reduces the difficulty of arranging equipment and pipelines on the cargo tank deck 100, and lowers the installation cost of the cargo tank monitoring device on the deck.

[0025] Optionally, the multiple monitoring instruments include at least a radar level sensor 320, a high-level alarm sensor 330, a high-high-level alarm sensor 340, a pressure monitoring sensor 350, and a deck sealing valve 310.

This protective component is disposed on the side of the common cover 230 away from the support tube 210 and surrounds the outer periphery of the plurality of mounting holes 240. The aforementioned protective component can protect the plurality of monitors from impact.

[0029] Optionally, the protection assembly includes multiple uprights 260 and connecting rings 270. The multiple uprights 260 are arranged around the outer periphery of multiple mounting holes 240, and the top of each of the multiple uprights 260 is connected to the connecting ring 270. The above protection assembly has a simple structure and is also convenient for pipeline routing.

[0030] Optionally, the protection assembly also includes a side retaining ring 280, with multiple uprights 260 connected to the side retaining ring 280, and the side retaining ring 280 located between the connecting ring 270 and the cover plate 230 to further improve the protection effect.

[0031] Optionally, the upright 260 and the cover plate 230 are bolted together to facilitate the replacement of the protective components.

[0032] This application also provides a ship, including a scheme for centralized arrangement of the above-mentioned liquid cargo tank deck 100 monitoring instruments.
