Description

Technical Field

[0001] This application relates to the technical field of automatic fire extinguishing, and particularly to a monorail crane fire extinguishing system with an automatic fire extinguishing and delayed flameout function. Background Art

[0002] The monorail crane main engine is a diesel-powered device, and the operating environment is mostly in mines with high temperature, dust, and continuous 24-hour operation. Fuels such as diesel, engine oil, and hydraulic oil used during vehicle operation are highly flammable, and combustibles such as coal powder and oil stains will also accumulate during the working process. In the case of poor heat dissipation, the surface temperatures of multiple heat source surfaces such as the cylinder block, exhaust manifold, turbocharger, generator, and hydraulic pump of the diesel engine are very high, which is likely to cause a fire. Currently, the mainstream automatic fire extinguishing systems can only trigger the fire extinguisher through the physical characteristics of thermal-sensitive pressure relief components (glass bulbs). This method can only be effectively triggered when an open fire occurs and cannot control the fire in advance. Summary of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.

[0021] Next, in conjunction with the attached Figure 1 The present application will be further described in detail. The embodiment of the present application discloses a single-rail hoist fire extinguishing system with an automatic fire extinguishing and delayed flameout function. It includes a temperature sensor 1, which is arranged near the heat source. Usually, the heat sources include a turbocharger, a generator, a hydraulic pump, etc. Therefore, there are at least two or more temperature sensors 1 to cover at least two or more heat sources, or temperature sensors 1 can be arranged near all heat sources.

[0022] The temperature sensor 1 is connected to a controller 2, and the controller 2 is connected to a solenoid valve 3. The temperature sensor 1 sends the electrical signal of the temperature to the controller 2. The controller 2 judges whether the temperature reaches the set threshold. If the temperature reaches the set threshold, the controller 2 starts the solenoid valve 3 according to the preset program.

[0023] It also includes a hydraulic accumulator 4. The hydraulic accumulator 4 is connected to an actuating cylinder 5, and the solenoid valve 3 is connected between the hydraulic accumulator 4 and the actuating cylinder 5. Energy is stored by the hydraulic accumulator 4, and the energy stored by the hydraulic accumulator 4 is used to push the actuating cylinder 5 to make the actuating cylinder 5 expand and contract. The solenoid valve 3 is used to control the actual expansion and contraction movement of the actuating cylinder 5. In this embodiment, the solenoid valve 3 is started according to the electrical signal of the controller 2, and then the expansion and contraction movement of the actuating cylinder 5 is controlled.

[0024] At the corresponding position of the expansion and contraction end of the actuating cylinder 5, there is a fire extinguishing tank 6, and the fire extinguishing tank 6 is connected to a spray head 7. The fire extinguishing tank 6 is provided with a sealing film, and the sealing film is arranged at the position corresponding to the expansion and contraction end of the actuating cylinder 5. The expansion and contraction end of the actuating cylinder 5 extends outwards to pierce the sealing film of the fire extinguishing tank 6, so that the fire extinguishing liquid in the fire extinguishing tank 6 flows out to the spray head 7, and the fire extinguishing agent is sprayed by the spray head 7 to achieve the fire extinguishing function. In order to better achieve the effect of piercing the sealing film, the expansion and contraction end of the actuating cylinder 5 is provided with a spike. Further, in order to improve the fire extinguishing effect, there are at least two spray heads 7, and more can be set according to the actual situation, which is used to improve the fire extinguishing effect.

[0025] The controller 2 is connected to an audible and visual alarm 8. When the dangerous signal of the temperature sensor 1 is sent to the controller 2, it can not only achieve the function of automatic fire extinguishing, but also give an alarm warning to the operator. The audible and visual alarm 8 has a dual alarm function of hearing and vision, which helps to prevent the situation that the operator's attention is not concentrated. At the same time, the controller 2 is connected to a display screen, which clearly marks the temperature sensor 1 that gives an alarm, so that the operator can quickly understand the equipment corresponding to the fire source that generates the alarm.

[0026] The controller 2 is connected to the ECU 9 of the single rail crane engine. Through a preset program, the engine of the single rail is shut down to prevent the temperature of the heat source from rising further and prevent the occurrence of fire in advance.

[0027] Working principle: Two temperature thresholds are set in the controller 2. The first temperature threshold indicates that the heat source is abnormal, and the second temperature threshold indicates a fire. By arranging the temperature sensor 1 on the surfaces of multiple heat sources such as generators, turbochargers, and hydraulic pumps to monitor the temperature in real time, when the temperature exceeds the set first temperature threshold, the controller 2 sends a signal to the ECU 9 of the engine to shut down the engine after a period of time, achieving a delayed shutdown to prevent the temperature from rising further, and controlling the audible and visual alarm 8 to give an alarm. The temperature sensor corresponding to the high-temperature heat source is displayed on the display screen, so that the staff can promptly check the high-temperature heat source and prevent the occurrence of fire.

[0028] When the temperature exceeds the set second temperature threshold, a fire is determined to have occurred. The controller 2 controls the solenoid valve 3 to start. The actuating cylinder 5 extends under the push of the hydraulic accumulator 4. The spike at the telescopic end of the actuating cylinder 5 pierces the sealing film of the fire extinguishing tank 6, causing the fire extinguishing agent in the fire extinguishing tank 6 to gush out and spray out from the nozzle 7 to achieve the fire extinguishing effect.

The components shown as units may or may not be physical units. They may be located in one place or distributed to multiple network units.
