Description

Technical Field

[0001] The present application relates to the field of steam pipeline protection, and specifically to a spraying method, device, equipment and system for steam pipeline leakage. Background Art

[0002] Steam pipelines are widely used in fields such as shipbuilding and marine engineering, energy, and power generation. Due to the long-term exposure to high temperatures, pressure loads caused by high pressure, erosion caused by high flow rates, and corrosion during long-term use, steam pipelines can become damaged, causing high-temperature steam leaks and overflows, impacting the safety and normal operation of the pipeline system and, in severe cases, even causing casualties and significant economic losses. Therefore, timely and effective spraying of steam leaks is crucial for the safety of those at risk.

[0003] After detecting a steam leak, traditional sprinkler systems often manually open the sprinkler valves on site. This method is relatively simple, but for more complex working environments, there are often more sprinkler valves involved. In order to ensure that all people in danger can escape with the help of sprinklers, relevant personnel need to open all the sprinkler valves. At this time, there is a great pressure on the water storage capacity of the sprinkler system. At the same time, for people in danger who need to be transferred, the transfer efficiency will be affected when there is spray water everywhere. Summary of the Invention

[0043] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] In some processes described in the embodiments of the present application, multiple operations or steps are included that appear in a specific order. However, it should be understood that these operations or steps may not be performed in the order in which they appear in the embodiments of the present application or may be performed in parallel. The sequence numbers of the operations are only used to distinguish between different operations, and the sequence numbers themselves do not represent any order of execution. In addition, these processes may include more or fewer operations, and these operations or steps may be performed in sequence or in parallel, and these operations or steps may be combined.

[0048] Traditional sprinkler systems often rely on manual opening of sprinkler valves upon detecting a steam leak. This method is relatively simple, but difficult to operate in areas with high steam density and is now being replaced by remote control. However, precise sprinkler technology is still lacking. With numerous steam pipelines, opening all control valves simultaneously can result in insufficient spray water, wasting the total flow of the sprinkler pump, compromising spray effectiveness, and even causing further steam spread.

[0049] In a first aspect, an embodiment of the present application provides a method for spraying a leaked steam pipe, which adopts the following technical solution:

[0050] A method for spraying a leaky steam pipe, comprising the following steps:

[0051] S100: If a steam leakage alarm signal is triggered, obtain the steam leakage location and the location of the person in danger;

[0052] S200, according to the leakage location and the location of the person in danger, obtaining an evacuation route starting from the location of the person in danger, not passing through the leakage location, and having the shortest evacuation distance;

[0053] S300: Determine an evacuation spraying area on the evacuation path that requires spraying treatment; wherein the evacuation spraying area is a continuous path including the location of the endangered person;

[0054] S400: spraying the evacuation spraying area.

[0055] In the above process, the location of the person in danger is realized by the information collection device installed in the passage and room. The information collection device can be a camera, an intercom, a signal trigger, etc. that can allow the outside world to obtain the presence of the person in danger in the current area. The embodiments of this application do not require this. At the same time, because the location of the person in danger changes in real time, the evacuation path and evacuation spray area obtained based on the location of the person in danger can be calculated in real time in some embodiments of this application, or can be calculated based on the latest location of the person in danger after a certain period of time. This application does not impose any restrictions on this.

[0056] When the evacuation path is calculated in step S200, it is also necessary to use the pre-set building indoor space parameters and generate a subsequent evacuation path based on the building indoor space parameters combined with the leakage location and the location of the endangered person.

[0057] Regarding the evacuation spray area in step S300, different parts of the evacuation path can be selected in different embodiments. For example, in some embodiments, the entire evacuation path is used as the evacuation spray area, that is, the entire evacuation path is sprayed. In other embodiments, the evacuation path at the location of the endangered person and a portion of the evacuation path in front of it can be used as the evacuation spray area to ensure that the endangered person can continue to walk within the spray area during the transfer. In addition, it is understood that for areas that the endangered person has already walked through, according to the definition of the evacuation path in this application, these areas that have been walked through are not on the evacuation path and are not within the selection range of the evacuation spray area. Therefore, for areas that were once selected as evacuation spray areas but have been walked through, this application no longer recognizes such areas as evacuation spray areas.

[0058] This setting generates the shortest evacuation path that does not pass through the leakage location from the location of the endangered person, and sets up the evacuation spray area in a targeted manner on the shortest evacuation path, so that the endangered person can be targetedly sprayed for protection during the evacuation route, avoiding the waste of spray water in other unrelated areas. At the same time, the endangered person can be quickly transferred to a safe area by moving along the evacuation spray area where spraying is being carried out. The evacuation path is clearer, which further improves the evacuation efficiency of the endangered person and improves the safety during the evacuation process.

[0059] In combination with the first aspect, in one embodiment, the evacuation spray area is the entire evacuation path, or the evacuation spray area is a portion of the evacuation path extending a set distance from the position of the person in danger.

[0060] This arrangement, when the entire evacuation path is used as the evacuation spray zone for the transfer of endangered personnel, will make the overall execution process more indirect, easier to implement, and effectively reduce the risk of program control problems. When a portion of the evacuation path is used as the evacuation spray zone, it can effectively reduce the consumption rate of the spray water reserve, ensuring that the water reserve can effectively support the entire evacuation process.

[0061] In combination with the first aspect, in one embodiment, in step S300, determining the evacuation spraying area on the evacuation path that needs to be sprayed,

[0062] S310, obtaining the water storage amount of the spray device;

[0063] S320: Determine an evacuation spraying area on the evacuation path that requires spraying according to the stored water volume.

[0064] With this arrangement, the evacuation spraying area requiring spraying operation is dynamically determined according to the current water storage capacity of the spraying device, thereby improving the safety of people in danger during evacuation.

[0065] Specifically, in one embodiment, in step S320, the evacuation spraying area that needs to be sprayed on the evacuation path is determined based on the stored water volume.

[0066] S321, obtaining the simulated passage time required for the endangered persons to pass through the remaining evacuation routes and the spray flow rate of the remaining evacuation routes;

[0067] S322: Calculate, based on the simulated passage time and the spray flow rate, the maximum safe distance at which the stored water can maintain spraying during the simulated passage time;

[0068] S323: Determine the portion of the evacuation path extending from the location of the endangered person to the maximum safety distance as the evacuation spray area.

[0069] This setting ensures that the water storage capacity can meet the needs of people in danger to be transferred to a safe location smoothly. At the same time, the evacuation spray area set up in this process is the longest distance that the water storage capacity can support, which makes it convenient for people in danger to transfer a longer distance during each movement, so that people in danger can escape danger quickly.

[0070] In combination with the first aspect, in one embodiment, in S200, based on the leakage location and the location of the person in danger, an evacuation route starting from the location of the person in danger, not passing through the leakage location and having the shortest evacuation distance is obtained.

[0071] If there are multiple locations of the person in danger, an independent evacuation path is generated for each location of the person in danger.

[0072] This setting ensures that all people in dangerous locations can be transferred to a safe area by the fastest route, further improving the safety of people in multiple different locations.

[0073] In combination with the first aspect, in one embodiment, in step S200, according to the leakage location and the location of the person in danger, an evacuation route starting from the location of the person in danger, not passing through the leakage location and having the shortest evacuation distance is obtained.

[0074] If there are multiple locations of the person in danger, the evacuation path connects each location of the person in danger in sequence.

[0075] This setting can reduce the system calculation amount as much as possible while effectively controlling the overall distance of the evacuation path. For the evacuation spray area set on the evacuation path, the total amount of water storage required is also small, and the pressure for the spray water storage is also small.

[0076] In conjunction with the first aspect, in one embodiment, the method further includes:

[0077] S500, determining an anti-diffusion spraying area surrounding the leakage location according to the leakage location;

[0078] S600: spraying the anti-diffusion spraying area.

[0079] Among them, step S600 is executed after step S500, but there is no fixed requirement on the order between step S500 and steps S200, S300, and S400, which may be different in different embodiments.

[0080] In this way, by defining an anti-diffusion spraying area around the leakage location, when the anti-diffusion spraying area is sprayed, the diffusion of steam at the leakage location can be effectively restricted, thereby reducing the impact of steam on the room.

[0081] Secondly, refer to Figure 2 , the embodiment of the present application provides a spray device for steam pipe leakage, which adopts the following technical solutions:
