Technical Field

[0001] The present invention belongs to the technical field of fire prevention and control in a crane electrical room, and in particular relates to a crane electrical room and a fire monitoring system and a fire monitoring method thereof. Background Art

[0002] Electrical fires generally refer to heat energy released due to faults in electrical circuits, electrical equipment, appliances, and power supply and distribution equipment: such as high temperature, electric arcs, electric sparks, and energy released due to non-fault conditions, such as the hot surface of electric heating appliances, which ignites the main body or other combustibles under the conditions of combustion. It also includes fires caused by lightning and static electricity. The faulty part will heat up locally for a long time, causing further degradation of insulation, and ultimately causing a short circuit in the line.

[0003] The crane electrical room is the main location of the power distribution part of the electrical control system. It is a relatively sealed and independent space, which is prone to fire disasters caused by electrical sparks, cable heating, etc. Depending on the complexity of the power distribution system, the size ranges from tens of cubic meters to hundreds of cubic meters. At present, there is a lack of fire monitoring, and it is impossible to respond immediately after a fire occurs, requiring manual fire extinguishing. In summary, there is an urgent need for a crane electrical room and its fire monitoring system and fire monitoring method. Summary of the invention

According to the real-time picture of the monitoring module 3, the identification unit can perform the first operation and the second operation; the communication module 4, the monitoring module 7, the fire extinguishing module 8, the monitoring module 3, and the purification module 6 are all arranged in the electrical room of the crane. The communication module 4 has a communication interface and is connected to the fire protection system in the factory. The monitoring module 7 is used to monitor the occurrence of fire in the space. In actual use, the monitoring module 7, the monitoring module 3, and the fire extinguishing module 8 are installed in various areas of the electrical room of the crane. The components in different positions can be monitored, monitored, and extinguished. The fire extinguishing module 8 can extinguish the fire in the area where it is located. The monitoring module 3 is used to upload the real-time pictures of multiple areas in the electric crane to the interactive module 2. The purification module 6 is used to ventilate the electrical room of the crane.

[0027] As a specific implementation, in the fire monitoring system for the crane electrical room of the present invention, the fire extinguishing module 8 includes a plurality of fire extinguishing nozzles arranged in the crane electrical room. Of course, the distribution positions of the fire extinguishing nozzles are set according to the positions of the components in the crane electrical room during actual use. When the control module 1 transmits a fire extinguishing signal to the fire extinguishing module 8, the fire extinguishing nozzles spray out an inert gas to extinguish the fire. More specifically, the inert gas is heptafluoropropane gas.

[0028] As a specific embodiment, in the fire monitoring system for the crane electrical room of the present invention, the alarm module 5 is respectively arranged inside and outside the crane electrical room, including a warning light and a sound unit. During actual use, under normal circumstances, the warning light is displayed in green and the sound unit is in the off state. When the control module 1 transmits an alarm signal to the alarm module 5, the warning light turns to flashing red and the sound unit emits a whistle sound to remind the staff that a fire has occurred in the crane electrical room.

[0029] As a specific embodiment, in the fire monitoring system for the crane electrical room of the present invention, the purification module 6 includes a ventilation fan arranged on the crane electrical room. During actual use, the ventilation fan is in a sealed state. When the control module 1 transmits a purification signal to the purification module 6, the ventilation fan starts and is connected between the inside and outside of the crane electrical room. The toxic gas in the electrical room can be quickly discharged through the purification module 6, thereby achieving the purpose of air purification in the crane electrical room.

[0030] As a specific implementation, in the fire monitoring system for the crane electrical room of the present invention, the monitoring module 7 includes a smoke sensing unit and a temperature sensing unit. During actual use, whether the smoke sensing unit detects smoke or the temperature sensing unit detects that the temperature of the target component exceeds the preset temperature, the monitoring module 7 will transmit the warning information to the control module 1.

[0031] The fire monitoring method for a crane electrical room of the present invention is implemented using the above-mentioned fire monitoring system, and specifically comprises the following steps:

[0032] Step 1: After the monitoring module 7 detects a fire in the crane electrical room, it transmits the warning information to the control module 1. The control module 1 sends the warning information to the interaction module 2, and at the same time controls the alarm module 5 to perform the alarm work, and sends the warning information to the fire protection system through the communication module 4;

[0033] Step 2: The interactive module 2 issues a reminder alarm, and the display unit interface automatically switches to the video screen of the fire area provided by the monitoring module 3. The recognition unit captures the details of the screen on the display unit, such as whether the smoke area in the video screen provided by the monitoring module 3 exceeds the preset value, whether there is an open flame in the screen, and other details, and accordingly performs the first operation and the second operation. The first operation is that the recognition unit recognizes that the fire is real, and then controls the fire extinguishing module 8 in the fire area through the control module 1 to work until the recognition unit determines that the fire is over, and then controls the communication module 4, monitoring module 7, alarm module 5, and fire extinguishing module 8 to restore the initial state through the control module 1. The criterion for the recognition unit to judge that the fire is over may be whether there is an open flame in the screen, etc. The second operation is that the recognition unit recognizes that no fire has occurred in the area, and then controls the communication module 4, monitoring module 7, and alarm module 5 to restore the initial state through the control module 1.

[0034] As a specific implementation method, in the fire monitoring method for the crane electrical room of the present invention, after the fire extinguishing module 8 completes the fire extinguishing work, the control module 1 controls the purification module 6 to ventilate the crane electrical room with the outside world. This setting is to discharge the toxic gas generated by the combustion in the crane electrical room and the inert gas sprayed by the fire extinguishing nozzle out of the crane electrical room, thereby eliminating toxic waste gas and purifying the air, making it convenient for the next maintenance personnel to enter the crane electrical room for inspection.

[0035] On the other hand, the present invention further provides a crane electrical room, which comprises the above-mentioned fire monitoring system.

[0036] In summary, compared with the prior art, the crane electrical room and its fire monitoring system and fire monitoring method of the present invention have the following advantages and positive effects:

[0037] The present invention can monitor and accurately identify fires in the electrical room of the crane in real time. When the monitoring module 7 detects a fire, it will immediately transmit a signal to the control module 1, which will be identified by the identification unit, and the alarm module 5 will sound an alarm simultaneously to promptly notify the staff. When the identification unit identifies a fire, the control module 1 can control the fire extinguishing module 8 to extinguish the fire, and purify the air in the electrical room of the crane after the fire is extinguished, thereby creating a safe environment for maintenance personnel to enter the site. The present invention has good practicality and safety, greatly reduces the losses caused to the crane by a fire in the electrical room of the crane, and reduces the probability of major accidents.
