Description

Technical Field

[0002] Common power stations such as mobile cabin power stations, trailer power stations, unattended power stations that automatically operate in strict high-altitude areas, etc. are all closed power stations. The generator set is the main equipment when the power station supplies power, providing electrical energy for electrical equipment in a timely manner. However, a large amount of heat is generated during the operation of the generator set, and there are also equipment such as high-voltage switch cabinets and low-voltage switch cabinets in the power station. These equipment will also generate a certain amount of heat during operation. Since the internal space of the closed power station is narrow and high temperature is not easy to discharge, the internal environmental temperature is relatively high, and there is a hidden danger of fire. At the same time, due to the improvement of the automation level of the power distribution equipment in the power station, the number of precision electronic components such as sensors and collectors used in the power distribution equipment has increased accordingly, and the corresponding failure risks have also increased. Therefore, a fire-fighting system needs to be equipped to extinguish fires when a fire accident occurs.

[0029] The following will combine the description of the drawings to provide a detailed explanation and description of the temperature-controlled fire protection system for the closed power station and the closed power station provided by the present utility model.

[0030] This embodiment specifically discloses a temperature-controlled fire protection system for an enclosed power station. As Figure 1 shown, the enclosed power station includes a control room 7, a unit room 8, and an exhaust room 9 that are isolated from each other. The control room 7, the unit room 8, and the exhaust room 9 are separated by a partition 10. There are doors on the partition 10. A control cabinet is provided in the control room 7 for the overall control of the power station. There are often staff entering the control room 7 for operation and control. As Figure 1 and 2 shown, the temperature-controlled fire protection system includes a first temperature sensor 1, a second temperature sensor 1', a first fire detector 4, a second fire detector 4', a temperature control device 2, a fire extinguishing gas storage tank 3, an electric louver 5, and a controller 6. The first temperature sensor 1 is arranged inside the control room 7 for detecting the temperature inside the control room 7; the second temperature sensor 1' is arranged inside the unit room 8 for detecting the temperature inside the unit room 8; the first fire detector 4 is arranged inside the control room 7 for detecting whether a fire occurs inside the control room 7; the second fire detector 4' is arranged inside the unit room 8 for detecting whether a fire occurs inside the unit room 8; in this embodiment, the first fire detector 4 and the second fire detector 4' are smoke monitoring sensors and / or infrared monitoring sensors. As Figure 1 、 3 and as shown in 4, the first fire detector 4 is arranged on the top wall of the control room 7, and the second fire detector 4' is arranged on the top wall of the unit room 8.

[0031] The temperature control end of the temperature control device 2 is arranged inside the control room 7 for controlling the temperature inside the control room 7. Since there may be staff working inside the control room 7, it is necessary to control the temperature inside the control room 7 within a suitable range. The temperature control device 2 can refrigerate or heat as needed to control the temperature inside the control room 7 at a suitable temperature. In this embodiment, the temperature control device 2 is an air conditioner, and the outdoor unit of the air conditioner is fixed on the outer wall of the enclosed power station.

[0032] The fire extinguishing gas storage tank 3 is arranged inside the enclosed power station. The fire extinguishing gas storage tank 3 stores fire extinguishing gas. The air outlet pipe of the fire extinguishing gas storage tank 3 includes a first air outlet pipe 31 and a second air outlet pipe 32. The air outlet of the first air outlet pipe 31 is arranged inside the control room 7, and the air outlet of the second air outlet pipe 32 is arranged inside the unit room 8. A first normally closed solenoid valve 33 is provided on the first air outlet pipe 31, and a second normally closed solenoid valve 34 is provided on the second air outlet pipe 32. When the normally closed solenoid valve is opened, the fire extinguishing gas in the fire extinguishing gas storage tank 3 sprays out for fire extinguishing; preferably, the gas in the fire extinguishing gas storage tank 3 is perfluorinated hexanone. The gas is clean and is used for enclosed fire extinguishing, which will not cause damage to various equipment, lines, documents, and precision instruments in the power station and will not affect their subsequent use. At the same time, the residue of perfluorinated hexanone gas will not cause personal injury.

[0033] Optionally, asFigure 1 , 3 As shown in FIGS. 3 and 4, the fire extinguishing gas storage tank 3 is detachably fixed in the control room 7 or the unit room 8 through the hoop 11. The hoop 11 is annular and has connecting ears at both ends. The annular part of the hoop 11 holds the tank body of the fire extinguishing gas storage tank 3, and the fire extinguishing gas storage tank 3 is surrounded between the hoop 11 and the wall of the enclosed power station (the partition 10 in this embodiment), and then the connecting ears are fixedly connected to the wall of the enclosed power station through bolts and nuts. At least two hoops 11 can be arranged along the height direction of the fire extinguishing gas storage tank 3. The detachable connection between the fire extinguishing gas storage tank 3 and the enclosed power station is realized through the hoop 11, so that the fire extinguishing gas storage tank 3 can be replaced regularly to prevent expiration, and the fire extinguishing gas can be replenished in time. A bracket can also be provided at the bottom of the fire extinguishing gas storage tank 3, and shock absorbers can be arranged between the bracket and the bottom wall of the enclosed power station and between the bracket and the fire extinguishing gas storage tank 3 to reduce the influence of the vibration generated during the operation of the generator set on the fire extinguishing gas storage tank 3.

[0034] Optionally, as Figure 1 , 3 and 4 show that the air outlet of the first air outlet pipe 31 is arranged at the end of the first air outlet pipe 31, and a nozzle 35 is connected at the air outlet of the first air outlet pipe 31. The nozzle 35 is close to the top of the control room 7, and the fire extinguishing gas sprayed by the nozzle 35 is divergent downward to improve the fire extinguishing ability; the probability of the unit room 8 catching fire is the greatest. Therefore, air outlets are provided on both the pipe wall and the end of the second air outlet pipe 32. One or more air outlets are provided on the pipe wall of the second air outlet pipe 32, and a nozzle 35 is connected at the air outlet of the second air outlet pipe 32, that is, a plurality of nozzles 35 can be arranged along the length direction of the second air outlet pipe 32 to enhance the fire extinguishing effect, and at least air outlets and nozzles 35 are provided directly above the generator set to improve the fire extinguishing ability.

[0035] The electric louver 5 is arranged on the side wall of the unit room 8 adjacent to the partition 10 for ventilation and heat dissipation. The number and specific position of the electric louvers 5 are set according to the actual ventilation needs. The electric louvers 5 are driven to open and close electrically, and its transmission mechanism can adopt existing transmission mechanisms such as a motor cooperating with a rack and pinion. The main equipment in the unit room 8 is the generator set. When the generator set operates, it needs to inhale and discharge a large amount of air, and a large amount of heat is generated during the operation of the generator set. The setting of the electric louver 5 can ensure the normal operation of the generator set and play a role in ventilation and heat dissipation; preferably, as Figure 1 shown, electric louvers 5 are arranged on both side walls of the unit room 8 adjacent to the partition 10, and the two electric louvers 5 are arranged opposite to each other to increase the air flow, improve the ventilation and heat dissipation ability, ensure the operation of the generator set, and minimize the possibility of fire.

[0036] As Figure 2As shown, the first input terminal of the controller 6 is electrically connected to the first temperature sensor 1 and the first fire detector 4. The first output terminal of the controller 6 is electrically connected to the temperature control device 2 and the first normally closed solenoid valve 33. A control room temperature threshold is preset in the controller 6. The first temperature sensor 1 transmits the temperature data collected in the control room 7 to the controller 6. The controller 6 compares the received temperature data with the preset temperature threshold and controls the temperature control device 2 and the first normally closed solenoid valve 33 accordingly. The first fire detector 4 detects fire information and transmits the information to the controller 6. After receiving the fire information, the controller 6 controls the first normally closed solenoid valve 33 to open. The temperature threshold in the control room 7 includes a first temperature threshold, a second temperature threshold range, a third temperature threshold, and a fourth temperature threshold. The first temperature threshold < the second temperature threshold range < the third temperature threshold < the fourth temperature threshold. When the temperature in the control room 7 detected by the first temperature sensor 1 is less than the first temperature threshold, the controller 6 controls the temperature control device 2 to heat up so that the temperature rises to within the second temperature threshold range. When the temperature in the control room 7 detected by the first temperature sensor 1 is higher than the third temperature threshold but lower than the fourth temperature threshold, the controller 6 controls the temperature control device 2 to cool down so that the temperature drops to within the second temperature threshold range. When the temperature in the control room 7 detected by the first temperature sensor 1 is higher than the fourth temperature threshold, it is determined that a fire has occurred in the control room, and the controller 6 opens the first normally closed solenoid valve 33 to release the fire extinguishing gas for fire extinguishing. Or when the first fire detector 4 detects a fire in the control room 7, the controller 6 opens the first normally closed solenoid valve 33 to release the fire extinguishing gas for fire extinguishing. As long as one of the first temperature sensor and the first fire detector 4 detects a fire in the control room 7, the controller 6 opens the first normally closed solenoid valve 33 to release the fire extinguishing gas for fire extinguishing.

[0037] The second input terminal of the controller 6 is electrically connected to the second temperature sensor 1' and the second fire detector 4'. The second output terminal of the controller 6 is electrically connected to the second normally closed solenoid valve 34 and the electric louver 5. The main equipment in the unit room 8 is the generator set. The operation of the generator set will generate a large amount of heat, and the risk of fire in the unit room 8 is also relatively high. Generally, the staff will not enter the unit room 8. Therefore, the unit room 8 mainly monitors for fires. A fifth temperature threshold is pre-stored in the controller 6. The fifth temperature threshold is used as the judgment criterion for the occurrence of a fire. The second temperature sensor 1' continuously detects the temperature in the unit room 8 and transmits the temperature data to the controller 6. The controller 6 receives the temperature data and compares the temperature data with the fifth temperature threshold. If the temperature in the unit room 8 exceeds the fifth temperature threshold, it is determined that a fire has occurred in the unit room 8. The controller 6 controls the electric louver 5 to close and simultaneously opens the second normally closed solenoid valve 34 to spray fire extinguishing gas for fire extinguishing; alternatively, after the second fire detector 4' detects a fire signal, it transmits the signal to the controller 6. The controller 6 controls the electric louver 5 to close and simultaneously opens the second normally closed solenoid valve 34 to spray fire extinguishing gas for fire extinguishing. As long as one of the second temperature sensor and the second fire detector determines that a fire has occurred, the controller 6 controls the electric louver 5 to close and simultaneously opens the second normally closed solenoid valve 34 for fire extinguishing; with dual guarantees, the judgment is more accurate.

[0038] The control method of the controller 6 adopts the existing control method in the art. Its control method is the function of the controller 6 itself, and the controller 6 can adopt the commonly used control chips in the art.

[0039] In this embodiment, the first temperature threshold is -15°C, the second temperature threshold range is 20 - 30°C, the third temperature threshold is 40°C, and the fourth temperature threshold and the fifth temperature threshold are both 72°C.

[0040] Since the controller 6 and the unit room 8 are independent of each other, the temperature control and fire protection of the two rooms can be independently controlled respectively. Since there are staff working in the control room 7, temperature control is carried out in the control room 7. In terms of fire extinguishing control, fire extinguishing operations are carried out where a fire occurs, which is targeted and has higher efficiency.

[0041] In some embodiments, the temperature-controlled fire protection system of the present application further includes a first temperature difference alarm 12 and a second temperature difference alarm 13. The first temperature difference alarm 12 and the second temperature difference alarm 13 can be arranged on the outer wall of the enclosed power station. The first temperature difference alarm 12 is electrically connected to the first output terminal of the controller 6, and the second temperature difference alarm 13 is electrically connected to the second output terminal of the controller 6. After the first temperature sensor 1 transmits the detected temperature data in the control room 7 to the controller 6, the controller 6 performs calculations to calculate the heating rate. If the heating rate reaches the threshold and lasts for a preset time, the controller 6 controls the first temperature difference alarm 12 to give an alarm. After the second temperature sensor 1' transmits the detected temperature data in the unit room 8 to the controller 6, the controller 6 performs calculations to calculate the heating rate. If the heating rate reaches the threshold and lasts for a preset time, the controller 6 controls the second temperature difference alarm 13 to give an alarm. Specifically, the heating rate threshold and the duration threshold are set according to actual needs. For example, when the indoor temperature is below 25°C, an alarm is given if the heating rate reaches 3°C / min and the duration reaches 15 min, or if the heating rate reaches 20°C / min and the duration reaches 3 min; when the indoor temperature is below 40 - 3°C, an alarm is given if the heating rate reaches 3°C / min and the duration reaches 10 min, or if the heating rate reaches 20°C / min and the duration reaches 2 min; when the indoor temperature is below 40 + 3°C, an alarm is given if the heating rate reaches 3°C / min and the duration reaches 5 min, or if the heating rate reaches 20°C / min and the duration reaches 1 min. Preferably, the temperature difference alarm is an audible and visual alarm. The temperature rate threshold and the duration threshold in the control room and the unit room can be the same or different, that is, the alarm conditions for the temperature difference alarms in the two rooms can be the same or different.

[0042] In some embodiments, the temperature-controlled fire protection system of the present application further includes a first manual switch and a second manual switch. The first manual switch is electrically connected to the first normally closed solenoid valve 33, and the second manual switch is electrically connected to the second normally closed solenoid valve 34. The first manual switch and the second manual switch can be arranged on the inner wall of the control room 7. The first normally closed solenoid valve 33 can be manually controlled to open through the first manual switch to extinguish the fire in the control room 7; the second normally closed solenoid valve 34 can be controlled to open through the second manual switch to extinguish the fire in the unit room 8.

[0043] The present application also discloses an enclosed power station, such as Figure 1 、 3As shown in FIGS. 3 and 4, the temperature-controlled fire protection system for a closed power station including the above embodiments has a controller 6 that can be arranged in a control room 7. A first temperature sensor 1 is arranged in the control room 7 for detecting the temperature in the control room 7. A first fire detector 4 is arranged on the top wall of the control room 7 for detecting whether a fire occurs in the control room 7. The temperature control end of the temperature control device 2 is arranged in the control room 7 for maintaining the temperature in the control room 7 at a comfortable temperature by refrigeration or heating. A first normally closed solenoid valve 33 controls the on-off of a first air outlet pipe 31 for spraying fire extinguishing gas into the control room 7 to extinguish a fire. Electric louvers 5 are provided on both side walls of the unit room 8 adjacent to the partition 10. The electric louvers 5 on the two side walls are arranged opposite to each other to increase air flow and enhance the ventilation and heat dissipation effect. A second temperature sensor 1' is arranged in the unit room 8 for detecting the temperature in the unit room 8 and then judging whether a fire occurs. A second fire detector 4' is arranged on the top wall of the unit room 8 for detecting whether a fire occurs in the unit room 8. A second normally closed solenoid valve 34 controls the on-off of a second air outlet pipe 32 for spraying fire extinguishing gas into the unit room 8 to extinguish a fire. The controller 6 performs corresponding temperature control and fire extinguishing operations on the control room 7 and the unit room 8 according to the detected temperature and the detection results of the fire detectors, playing a dual protection role. In case of a fire, it can extinguish the fire in time and can extinguish the fire automatically without the need for personnel to enter the power station internally, with better safety.
