Description

Technical Field

[0001] This utility model relates to a monitoring device for monitoring oil spills from a broken hose, specifically a dual-tube external delivery hose oil spill monitoring device. Background Technology

[0002] Oil hoses used in offshore operations can break down and cause oil spills after prolonged use, potentially leading to unnecessary resource waste. To address this issue, alarm systems are typically designed into the hoses. These systems trigger an alarm upon detecting an oil spill. Furthermore, after extended offshore operations, the observation windows for marine life growth are easily contaminated, requiring extensive cleaning. Dual-body hoses are designed to minimize the possibility of environmental pollution and are therefore widely used in practice. Conventional dual-body hoses consist of two independent pressure shells: a main shell and a secondary shell. To detect potential damage to the main shell, a corresponding monitoring and alarm system is designed. Conventional dual-body hose oil spill monitoring systems primarily rely on mechanical alarms. While this structure can pinpoint leak locations, it requires manual inspection, which is labor-intensive and time-consuming. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a dual-tube external oil spill monitoring device that can minimize the drawbacks and workload caused by manual operation.

[0004] To solve the above-mentioned technical problems, the present invention provides a dual-tube external oil spill monitoring device, comprising an oil pipeline composed of multiple interconnected dual-tube hoses. Each dual-tube hose has a monitoring indicator at both ends. Each dual-tube hose contains a dye transfer tube arranged along its length. Both ends of each dye transfer tube extend beyond the dual-tube hose to form connectors. Each monitoring indicator is connected to the connector of the dye transfer tube in an adjacent dual-tube hose via a T-connector. The dye transfer tube is connected to an alarm system and can transmit the monitored information through the monitoring indicator to the alarm system for alarm activation.

[0005] Each of the aforementioned double-walled hoses is equipped with a connecting flange at both ends, and adjacent double-walled hoses are connected through the connecting flange.

[0006] Each of the aforementioned monitoring indicators is located at the connection flange of each of the aforementioned double-layer hoses.

[0007] The dye delivery tubes are wound inside each of the two-tube flexible tubes.

[0008] The alarm system is integrated into an alarm box, which is installed on a floating platform.

[0009] The alarm system includes an audible and visual alarm unit and a pressure switch connected to the audible and visual alarm unit.

[0010] The audible and visual alarm unit is connected to a solar panel and a rechargeable battery pack.

[0011] The dye delivery tubes are arranged along the length of each of the two-tube flexible tubes.

[0012] The advantages of this utility model are:

[0013] By directly configuring a monitoring indicator at each end of each double-tube hose and connecting each monitoring indicator to the connector end of the dye transfer tube in the adjacent double-tube hose via a T-connector, the system automatically and reliably collects, processes, and controls measurement data in an environmentally friendly and electronic manner. This improves the system's informatization and automation levels, and increases the speed of damage response. It transforms the previous manual inspection method into an unattended automatic monitoring and alarm method, ensuring the needs of long-distance monitoring and minimizing the drawbacks and workload of manual operation.

[0017] The oil spill monitoring device of the present invention, with reference to the accompanying drawings and specific embodiments, will be further described in detail below.

[0018] As shown in the figure, the oil spill monitoring device for the dual-tube external transfer hose of this utility model includes an oil pipeline 2 composed of multiple interconnected dual-tube hoses 1. As can be seen from the figure, each dual-tube hose 1 has a connecting flange 7 at both ends, and adjacent dual-layer hoses are connected through the connecting flange 7. Each dual-tube hose has a monitoring indicator 3 at both ends (product model DD51-E). Each monitoring indicator 3 is located at the connecting flange 7 of each dual-layer hose. Each dual-tube hose 1 has a dye transfer tube 4 embedded in it, arranged along the length of the hose. The two ends of each dye transfer tube 4 extend out of each dual-tube hose to form a connector. Each monitoring indicator 3 is connected through a T-type connector 5. The dye transfer pipe 4 is connected to the connector end of the adjacent double-tube hose 1. The dye transfer pipe 4 is connected to the alarm system 6 and can transmit the monitored information to the alarm system 6 through the dye transfer pipe to trigger an alarm. In other words, the double-tube external hose oil spill monitoring device of this utility model can provide real-time feedback on the pressure change of the external hose through the pressure transmission pipeline and provide pressure and color dye indicators. When the pressure reaches the specified threshold (the threshold can be adjusted before installation), such as 5 BAR, it is considered that there is an oil spill or suspected change in the inner wall of the pipeline and needs to be dealt with. At this time, the monitoring indicator, pressure sensor and color dye transmission device are triggered to work simultaneously, which can reduce the false alarm rate and allow for intuitive observation of the activation state.

[0019] Furthermore, the aforementioned alarm system includes an audible and visual alarm unit and a pressure switch connected to it. The audible and visual alarm unit is connected to a solar panel and a rechargeable battery pack, ensuring its maintenance-free and long-life operation. During use, if the monitoring indicator 3 is activated, it will discharge luminous liquid at 5 bar and provide a local fault indication. The pressure switch (model MIKPX300) inside the alarm box will trigger the audible and visual alarm and provide a remote signal (the default pressure activation value is 5 Bar, but it can also be set according to user requirements; the interface with the RTUB is 2 x 4-20mA analog input, using the HART protocol). The alarm system 6 is integrated into an alarm box, which is installed independently on the float platform.

[0020] In addition, the dye transfer tube 4 can be wound around the two layers of each double-tube hose 1, or it can be arranged along the length of the two layers of each double-tube hose 1.

[0021] Its working principle is:

[0022] Monitoring indicators 3 are symmetrically installed in pairs at the connection of the oil pipeline 2. At any given time, at least one pressure detection alarm device must be above the water surface and capable of wireless communication (i.e., the monitoring indicators at both ends of each double-walled hose are arranged symmetrically, with one indicator on top and the other on the bottom). Monitoring indicators 3 detect the pressure inside the transmission hose (dye transmission hose) in real time. If the pressure reaches a specified threshold (adjustable before installation), such as 5 Bar, it is considered that the inner wall of the oil pipeline 2 has been damaged and requires attention. At this time, an alarm signal is triggered and sent out through the network. The alarm system is connected to each monitoring indicator through the dye transmission hose. These transmission hoses are vulcanized into the outer shell of the double-walled oil transmission hose. This closed alarm system is filled with colored fluorescent liquid and is under controlled pressure. If a hose malfunctions, the indicator unit of the malfunctioning hose will be activated, and the valve inside the monitoring indicator will release the colored fluorescent liquid into the ocean.

[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
