Description

Technical field:

[0001] The present invention relates to the technical field of monitoring systems, in particular to a ship helium-oxygen cylinder compartment monitoring system and a ship thereof. Background technology:

[0002] Many special-purpose vessels equipped with helium and oxygen tank compartments are not equipped with such alarm systems. Instead, they rely on periodic inspections carried out by personnel using portable instruments during patrols. This inspection method cannot provide real-time monitoring of the helium and oxygen tank compartments at all times, cannot guarantee continuous safety and effectiveness, and cannot provide warnings before accidents occur.

[0003] In order to solve the problem of gas explosion-proof safety control in the helium-oxygen cylinder cabin, the volatilization amount, volatilization time and minimum explosion limit of the fuel (after the surrounding fuel tanks are damaged) are calculated according to the actual ambient temperature and the entire cabin. However, there are currently no indicators to conduct corresponding tests. Therefore, it is urgent to consider the detection and feedback alarm of the combustible gas and oxygen content concentration in the helium-oxygen cylinder cabin.

[0004] There is an urgent need for a ship with a ship helium-oxygen cylinder compartment monitoring system, which helps to solve the technical problem of the lack of a helium-oxygen cylinder air tightness monitoring method in the existing technology. Summary of the invention:

[0005] In one embodiment, the present invention provides a ship helium-oxygen cylinder cabin monitoring system, which sets a combustible gas probe in the cabin and uses a fan to reduce the solubility of excessively high solubility, helping to solve the technical problem of the lack of a helium-oxygen cylinder air tightness monitoring method in the prior art.

[0006] The ship helium-oxygen cylinder compartment monitoring system includes:

[0007] A plurality of combustible gas probes are installed in a helium-oxygen chamber, and a helium-oxygen cylinder is placed in the helium-oxygen chamber;

[0008] A system control box is connected to the combustible gas probe, detects the helium-oxygen concentration in the helium-oxygen chamber through the combustible gas probe, and determines whether it reaches a first predetermined concentration. When the helium-oxygen concentration in the helium-oxygen chamber reaches the first predetermined concentration, the fan is turned on to reduce the concentration of the gas in the helium-oxygen chamber to a second predetermined concentration.

[0009] In one embodiment, the ship's helium-oxygen tank compartment monitoring system further includes:

[0010] The first predetermined concentration is 20% LEL, and the second predetermined concentration is 5% LEL.

[0011] In one embodiment, the plurality of combustible gas probes is four and is distributed in the helium-oxygen chamber.

[0012] In one embodiment, the ship's helium and oxygen tank compartment monitoring system further includes an audible and visual alarm device and an explosion-proof audible and visual alarm;

[0013] The sound and light alarm device is connected to the system control box;

[0014] The explosion-proof sound and light alarm is connected to the system control box.

[0015] In one embodiment, the present invention further provides a ship having a ship helium-oxygen cylinder compartment monitoring system, wherein the ship includes the ship helium-oxygen cylinder compartment monitoring system.

[0016] In one embodiment, the ship has a volatile gas chamber, which contains oily substances. When the oily substances mix with the volatile gas in the helium-oxygen cylinder, combustible and explosive gas is generated.

[0017] In one embodiment, the blower sweeps toward a location with high concentration of the helium-oxygen chamber and cuts the flow direction of the oily substance.

[0018] In one embodiment, the ship has a spectral analysis device, which is used to monitor the flow direction of helium-oxygen gas and volatile gas of the oily substance, and prevent collision through the wind direction of the fan.

[0019] In one embodiment, the sound and light alarm device is installed in the damage control room and the cab.

[0020] In one embodiment, the ship's helium-oxygen cylinder compartment monitoring system has an automatic interlocking function, which interlocks the corresponding ventilation system after an alarm is issued. After the ventilation system is started, the gas is discharged to avoid concentration accumulation and increase. Description of the drawings:

[0044] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0045] First, we need to consider how to monitor the helium-oxygen cylinder room to solve the problem of long-term monitoring;

[0046] How to monitor combustible gas and oxygen separately in the cabin, whether they can be distinguished by using audible and visual alarm devices, and whether the alarm prompts are clear and unambiguous;

[0047] There is currently no sound and light alarm device at the duty station. How to extend the alarm to the duty station where someone is present? How is the alarm displayed?

[0048] When an alarm occurs, how to silence it, how to handle the alarm, how to reset the alarm, manually or automatically;

[0049] When an alarm is issued, how should the crew on board perform the next action? Can a ship's helium-oxygen cylinder compartment monitoring system play a corresponding role or function?

[0050] The present invention can realize real-time monitoring of the gas concentration between helium and oxygen cylinders and inform the on-duty personnel on board through an alarm. The on-duty personnel can take corresponding measures immediately after receiving the alarm, thereby ensuring the safety of the ship.

[0051] The present invention mainly solves the problem of explosion-proof safety control in the helium-oxygen cylinder compartment of special ships. It provides a monitoring and alarm measure, which automatically alarms and outputs a signal when the concentration of combustible gas and oxygen exceeds the standard. The present invention is further described below with reference to the accompanying drawings.

[0052] Figure 1 The figure is a schematic diagram of the architecture of a ship's helium-oxygen tank compartment monitoring system according to one embodiment of the present invention. Figure 2 Schematic diagram of the monitoring working mode of the helium-oxygen cylinder cabin in another embodiment of the present invention.

[0053] like Figure 1 and Figure 2 As shown, in one embodiment, the present invention provides a ship helium-oxygen cylinder compartment monitoring system, the ship helium-oxygen cylinder compartment monitoring system includes a plurality of combustible gas probes 1 and a system control box 2;

[0054] A plurality of combustible gas probes are installed in the helium-oxygen chamber 10, and a helium-oxygen cylinder 100 is placed in the helium-oxygen chamber 10;

[0055] The system control box 2 is connected to the combustible gas probe 1, which detects the helium-oxygen concentration in the helium-oxygen chamber 10 and determines whether it reaches a first predetermined concentration. When the helium-oxygen concentration in the helium-oxygen chamber 10 reaches the first predetermined concentration, the fan 3 is turned on to reduce the concentration of the gas inside the helium-oxygen chamber 10 to a second predetermined concentration.

[0056] This embodiment provides a specific implementation of a shipboard helium-oxygen cylinder compartment monitoring system. Helium-oxygen cylinders 100 are typically grouped together in a helium-oxygen chamber 10. A combustible gas probe 1 detects varying concentrations within the chamber. If the detected concentration reaches a first predetermined concentration, a blower 3 blows the gas to the location where the concentration reaches the first predetermined concentration, then stops when the concentration reaches a second predetermined concentration. Once the acceptable concentration is reached, personnel intervene to perform subsequent processing. This helps address the existing technical issue of a method for monitoring the tightness of helium-oxygen cylinders.

[0057] In one embodiment, the ship's helium-oxygen tank compartment monitoring system further includes:

[0058] The first predetermined concentration is 20% LEL, and the second predetermined concentration is 5% LEL.

[0059] In one embodiment, the number of the plurality of combustible gas probes 1 is four and they are distributed in the helium-oxygen chamber 10 .

[0060] In one embodiment, the ship's helium and oxygen cylinder compartment monitoring system further includes an audible and visual alarm device 4 and an explosion-proof audible and visual alarm 5;

[0061] The sound and light alarm device 4 is connected to the system control box 2;

[0062] The explosion-proof sound and light alarm 5 is connected to the system control box 2.

[0063] The sound and light alarm device 4 can expand the alarm range so that people who are not near the cabin can receive the alarm and take action.

[0064] In one embodiment, the present invention provides a ship having a ship helium-oxygen cylinder compartment monitoring system, wherein the ship includes the ship helium-oxygen cylinder compartment monitoring system.

[0065] In one embodiment, the ship has a volatile gas chamber, which contains oily substances. When the oily substances mix with the volatile gas in the helium-oxygen cylinder 100 , combustible and explosive gas is generated.

[0066] In one embodiment, the blower sweeps toward a location with high concentration of the helium-oxygen chamber 10 and cuts the flow direction of the oily substance.

[0067] In one embodiment, the ship has a spectral analysis device, and the spectral analysis device 6 is used to monitor the flow direction of the helium-oxygen gas and the volatile gas of the oily substance, and prevent collision through the wind direction of the fan.

[0068] The oily volatile gas and helium-oxygen gas have different spectra, and the flow direction of the gas is presented in the form of a spectrum. The fan is used to blow the area where the oily volatile gas and helium-oxygen gas may intersect, so that the two will not intersect and further form a gas that is easily combustible and explosive.

[0069] like Figure 2 As shown, the black arrow is the flow direction of helium and oxygen gases seen by the spectrum, and the white arrow is the flow direction seen by the spectrum. The areas where problems are more likely to occur are at the partition wall between two adjacent cabins, due to airtightness problems or volatile gases entering the cabin from the outside.

[0070] In one embodiment, the sound and light alarm device 4 is installed in the damage control room and the cab.

[0071] In one embodiment, the ship's helium-oxygen cylinder compartment monitoring system has an automatic interlocking function, which interlocks the corresponding ventilation system after an alarm is issued. After the ventilation system is started, the gas is discharged to avoid concentration accumulation and increase.

[0072] The fan's purge operating modes include:

[0073] In the single gas purge mode, there are multiple fans, which blow away the gas in the space where the first predetermined concentration is reached, causing it to drop to the space where the second predetermined concentration is reached, or even lower. The fans blow away the area where the helium and oxygen gas concentration increases, or / and blow away the area where the oily volatile gas concentration increases.

[0074] It is mainly used in the state where two gases are not intersecting, and the fan can blow in the opposite direction to the direction of the oily volatile gas.

[0075] The dual-gas purge mode is mainly used in the mixed state of two gases. It cuts the intersection position with high-pressure airflow and then purges in the opposite direction of the gas leakage.

[0076] Four combustible gas detectors are arranged in the helium-oxygen cylinder cabin, with the alarm setting value being 20% LEL, to detect the concentration of combustible gas in this cabin.

[0077] 2. Sound and light alarm devices shall be installed at the entrance of the helium and oxygen cylinder room, the damage control room and the cab to promptly alert relevant personnel and ensure safe use.

[0078] 3. An audible and visual alarm mute device shall be installed at the entrance of the helium and oxygen cylinder room, the duty room and the gas detection control box in the damage control room. When the alarm continuously outputs a flashing sound signal, the nearest personnel shall manually reset it.

[0079] When the gas concentration of the combustible gas detector exceeds 20%LEL, the fan control contact starts and the fan start signal is continuously sent. When the gas concentration drops to 5%LEL, the system returns to normal.

[0080] The present invention can completely change the monitoring method that requires onboard personnel to conduct inspections and field tests. This system can monitor the combustible gas and oxygen concentrations in the helium-oxygen cylinder compartment 24 hours a day. When the gas concentration exceeds the standard, an alarm will be issued and the alarm signal will be extended. The on-duty personnel on board can receive the alarm information immediately through remote monitoring. After receiving the alarm, the on-duty personnel on board will take corresponding measures immediately, thereby ensuring the safety of the ship.

[0081] Compared with the configuration before the invention:

[0082] Reduce personnel inspection work, greatly reduce personnel workload and manpower deployment on board;

[0083] It reduces the risk of ships, transforms inspections into real-time monitoring, and greatly improves the safety performance of ships;

[0084] The real-time monitoring system can predict accidents before they happen, and the recording function can assist in accident investigations on board, thereby better improving the safety performance of the ship;

[0085] This invention can effectively improve the ability of shipboard personnel to deal with accidents and eliminate safety hazards as soon as possible.

[0086] Accurately detect the concentration of different gases in professional cabins, send out different alarm signals and start fan interlocking to achieve effective control of explosion-proof safety.

[0087] 1. The first ship equipped with this invention has been delivered. The system is currently running well. The shipowner does not need to arrange personnel for inspection, and can monitor it in the duty room, which reduces the workload and inspection time of at least two inspectors.

[0088] 2. The invention has an automatic interlocking function, which interlocks the corresponding ventilation system after the alarm is issued. After the ventilation system is started, the gas is discharged to prevent the concentration from accumulating and causing an explosion in the cabin, thereby losing property and affecting the safety of the crew.

[0089] It has been installed and used on a certain series of ships, and the installation and commissioning have been completed. The system monitoring and alarm functions are very effective. The first ship has been delivered and is currently being promoted for use on subsequent ships in this series.

[0090] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
