Description

Technical Field

[0001] This invention belongs to the field of fire protection technology, specifically relating to fire protection of generator sets, and more particularly to a remote fire protection system and a diesel generator set using the system. Background Technology

[0002] When a diesel generator set catches fire, the system will shut down the diesel generator, but diesel fuel and oil pressure will still remain inside the pipeline. At this time, the high temperature of the fire will reduce the pressure-bearing capacity of the pipeline, which will lead to pipeline rupture, diesel fuel leakage, and the spread of the fire.

[0003] If a single metal pipe is used instead, the oil pressure problem can be solved, but the metal pipe will transfer the high temperature to the joint more quickly, causing the joint seal to fail.

[0004] Therefore, how to solve the problem of pipelines between diesel generators and fuel tanks being prone to rupture and leakage in a fire is a problem that urgently needs to be solved by those skilled in the art.

[0011] Secondly, this disclosure also provides a diesel generator set, including: a diesel generator, a fuel tank, and a remote fire suppression system; wherein the inner corrugated pipe of the remote fire suppression system is used to connect the diesel generator and the fuel tank.

[0012] Thirdly, this disclosure also provides a method for operating a remote fire suppression system, comprising: connecting a diesel generator and a fuel tank via a double-layer pipeline; acquiring and transmitting oil pressure data in the inner bellows via a pressure sensor; acquiring and transmitting ambient temperature data via a temperature sensor; when the diesel fuel in the inner bellows is waxy, controlling a gas circulation device via a remote control module to introduce heated gas into the sealed chamber to heat the diesel fuel; when the oil pressure data acquired by the pressure sensor is lower than a first threshold, controlling the gas circulation device via the remote control module to pressurize the sealed chamber to restore the oil pressure in the inner bellows; and when the temperature data acquired by the temperature sensor is higher than a second threshold, controlling a carbon dioxide fire extinguishing tank via the remote control module to introduce carbon dioxide gas into the sealed chamber to reduce the oil temperature in the inner bellows and extinguish the fire in the ambient environment.

[0013] In an alternative embodiment, in the method of pressurizing the sealed chamber by controlling the gas circulation device through the remote control module to restore the oil pressure of the inner bellows: when the working time of the gas circulation device exceeds a fourth threshold, the remote control module controls the diesel generator to stop working.

[0014] In an optional embodiment, in the method of controlling the carbon dioxide fire extinguishing tank to introduce carbon dioxide gas into the sealed chamber to reduce the oil temperature in the inner bellows and extinguish the fire in the external environment by means of a remote control module when the temperature data obtained by the temperature sensor is higher than the second threshold: a plurality of air jet holes are opened on the wall of the outer bellows; a hot melt material is placed in the air jet holes to seal the air jet holes; wherein the hot melt material melts when the temperature reaches a third threshold, and the third threshold is lower than the second threshold.

Simultaneously, the inner corrugated pipe is configured as a structure consisting of several sub-inner pipes and several connecting pipes for connecting adjacent sub-inner pipes. This allows the connecting pipes to expand under stress when the oil temperature in the inner corrugated pipe rises during a fire, thereby reducing the oil pressure in the inner corrugated pipe. Furthermore, during a fire, carbon dioxide gas is introduced into the sealed chamber from a carbon dioxide fire extinguishing tank to lower the oil temperature, and carbon dioxide gas is sprayed around the double-layer pipeline for fire suppression.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Carbon dioxide fire extinguishers contain liquid carbon dioxide. When sprayed, the liquid carbon dioxide vaporizes, thus absorbing heat.

[0027] The gas circulation device has a heating module for regulating the gas temperature.

[0028] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0029] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] like Figure 1 As shown, at least one embodiment provides a remote fire protection system, including: a double-layer pipeline 1, a gas circulation device, a carbon dioxide fire extinguishing tank, a pressure sensor, a temperature sensor, and a remote control module.

[0031] Specifically, such as Figure 2 As shown, the double-layer pipe 1 includes an outer corrugated pipe 11 and an inner corrugated pipe 12, with a sealed chamber 13 formed between the outer corrugated pipe 11 and the inner corrugated pipe 12. The inner corrugated pipe 12 is used to connect the diesel generator and the fuel tank.

[0032] Specifically, such as Figure 2 As shown, the gas circulation device is connected to the sealed chamber 13 through the second flow channel and the third flow channel respectively; wherein, valve 2 (i.e., the second solenoid valve) is provided on the second flow channel, and valve 3 (i.e., the third solenoid valve) is provided on the third flow channel.

[0033] Specifically, the carbon dioxide fire extinguishing tank is connected to the sealed chamber 13 through the first flow channel. The carbon dioxide fire extinguishing tank is used to spray carbon dioxide gas. The carbon dioxide gas has a low temperature and can be used for cooling and fire extinguishing. A valve 1 (i.e., the first solenoid valve) is installed on the first flow channel.

[0034] Specifically, the pressure sensor is used to acquire and transmit oil pressure data in the inner bellows 12.

[0035] Specifically, the temperature sensor is used to acquire and transmit temperature data of the external environment.

[0036] In the first application scenario, when the sidewall of the inner bellows 12 ruptures and leaks oil, the oil pressure data acquired by the pressure sensor will decrease. When the oil pressure data is lower than the first threshold, the remote control module controls the gas circulation device to pressurize the sealed chamber 13 by inflating it from the second flow channel (at this time, valves 1 and 3 are closed, and valve 2 is open). This reduces the pressure difference between the sealed chamber 13 and the inner bellows 12, preventing diesel from flowing out of the inner bellows 12 until the oil pressure data in the inner bellows 12 is restored. Subsequently, the gas circulation device enters a pressure-maintaining mode. The gas used is at room temperature. If the oil pressure data in the inner bellows 12 still has not been restored after the gas circulation device has reached the fourth threshold, it indicates that the leak sealing is not complete. At this time, the remote control module controls the diesel generator and fuel tank to shut down.

[0037] In the second application scenario, when it is necessary to defrost the waxed diesel fuel, the remote control module controls the gas circulation device to fill the sealed chamber 13 with heated gas from the second flow channel and circulate it (at this time, valve 1 is closed and valves 2 and 3 are open); the gas is a gas with temperature.

[0038] In the third application scenario, when a fire occurs, the temperature data acquired by the temperature sensor will rise. When the temperature data exceeds the second threshold, the remote control module controls the carbon dioxide fire extinguishing tank to introduce carbon dioxide gas into the sealed chamber 13 from the first flow channel (at this time, valve 1 is open, and valves 2 and 3 are closed). The carbon dioxide gas can reduce the oil temperature in the inner bellows 12, thereby reducing the oil pressure in the inner bellows 12. At the same time, the carbon dioxide gas will also be ejected from the jet holes generated by the high temperature melting on the side wall of the outer bellows 11, thereby extinguishing the fire in the area near the double-layer pipe 1.

[0039] like Figure 2 As shown, in some embodiments, the inner bellows 12 includes: a plurality of sub-inner tubes 121 and a plurality of connecting tubes 122 for connecting adjacent sub-inner tubes 121; wherein the connecting tubes 122 are elastic and adapted to expand under force when the oil temperature inside the inner bellows 12 rises to reduce the oil pressure.

[0040] Specifically, when a fire occurs, the remote control module shuts down the diesel generator and fuel tank, but there is still diesel fuel in the inner bellows 12. If the diesel fuel in the inner bellows 12 leaks, it will spread the fire.

[0041] In this embodiment, by employing a flexible connecting pipe 122, when the diesel fuel in the inner bellows 12 is pressurized due to temperature increase, the connecting pipe 122 can expand under force, thereby reducing the oil pressure in the inner bellows 12.

[0042] In some embodiments, a metal ring is provided inside the connecting pipe 122 to improve strength and limit the expansion range.

[0043] like Figure 2 As shown, in some embodiments, the outer corrugated pipe 11 has a plurality of air jet holes 111 on its pipe wall; the air jet holes 111 are filled with a hot melt material to seal the air jet holes 111; wherein the hot melt material is suitable to melt when the temperature reaches a third threshold, so that when the carbon dioxide fire extinguisher is working, the carbon dioxide gas in the sealed chamber 13 is sprayed out from the air jet holes 111 to extinguish the fire in the external environment; wherein the third threshold is less than the second threshold.

[0044] In this embodiment, the hot melt material melts when the temperature reaches the third threshold, and the third threshold is less than the second threshold, in order to prevent the situation where the jet hole 111 is not open when the carbon dioxide fire extinguisher is working. If the carbon dioxide fire extinguisher starts working and the jet hole 111 is not open, the pressure in the sealed chamber 13 will increase, which will pressurize the inner bellows 12 and promote the rupture of the inner bellows 12, resulting in diesel leakage.

[0045] In some embodiments, the jet holes 111 on the outer bellows 11 are distributed around the periphery of each connecting pipe 122; the connecting pipe 122 is adapted to reduce the flow cross section of the sealed chamber 13 when expanding, so that the jet holes 111 spray to a distance; the connecting pipe 122 is adapted to gradually reduce the expansion amplitude after carbon dioxide gas is introduced into the sealed chamber 13, so that the jet holes 111 spray to a nearby location.

[0046] Specifically, when the hot melt material melts, the connecting pipe 122 expands, which makes the flow channel inside the jet hole 111 smaller, that is, the flow velocity of carbon dioxide gas at that point increases, so that the carbon dioxide gas is ejected from the jet hole 111 a farther distance.

[0047] Specifically, when carbon dioxide gas comes into contact with the inner bellows 12, the carbon dioxide gas will cool the inner bellows 12, thereby reducing the oil pressure in the inner bellows 12, and thus reducing the expansion amplitude of the connecting pipe 122. That is, the flow rate of carbon dioxide gas at this point is reduced, which makes the distance of carbon dioxide gas ejected from the jet hole 111 shorter.

[0048] In this embodiment, the carbon dioxide gas ejected from the jet nozzle 111 first extinguishes the fire at a distance from the double-layer pipe 1 to form an isolation zone and prevent the fire from spreading to the double-layer pipe 1; then it gradually extinguishes the fire at a closer distance to put out any open flames that may arise near the double-layer pipe 1.

[0049] In some embodiments, the remote control module may be, but is not limited to, a PLC.

[0050] In some embodiments, the first threshold is pressure data, namely, the oil pressure data when diesel is normally transported in the inner bellows 12.

[0051] In some embodiments, the second and third thresholds are temperature data.

[0052] In some embodiments, the fourth threshold is time data.

[0053] At least one embodiment also provides a diesel generator set, including: a diesel generator, a fuel tank, and a remote fire suppression system; wherein the inner corrugated pipe 12 of the remote fire suppression system is used to connect the diesel generator and the fuel tank.

[0054] For details on the specific structure and implementation process of the remote fire protection system, please refer to the relevant discussions in the above embodiments, which will not be repeated here.

[0055] At least one embodiment also provides a method for operating a remote fire suppression system, comprising: connecting a diesel generator and a fuel tank via a double-layer pipe 1; acquiring and transmitting oil pressure data in the inner bellows 12 via a pressure sensor; acquiring and transmitting ambient temperature data via a temperature sensor; when the diesel fuel in the inner bellows 12 is waxy, controlling a gas circulation device via a remote control module to introduce heated gas into a sealed chamber 13 to heat the diesel fuel; when the oil pressure data acquired by the pressure sensor is lower than a first threshold, controlling the gas circulation device via the remote control module to pressurize the sealed chamber 13 to restore the oil pressure in the inner bellows 12; when the temperature data acquired by the temperature sensor is higher than a second threshold, controlling a carbon dioxide fire extinguishing tank via the remote control module to introduce carbon dioxide gas into the sealed chamber 13 to reduce the oil temperature in the inner bellows 12 and extinguish the fire in the ambient environment.

[0056] For details on the specific structure and implementation process of the remote fire protection system, please refer to the relevant discussions in the above embodiments, which will not be repeated here.

[0057] In the first application scenario, when the sidewall of the inner bellows 12 ruptures and leaks oil, the oil pressure data acquired by the pressure sensor will decrease. When the oil pressure data is lower than the first threshold, the remote control module controls the gas circulation device to pressurize the sealed chamber 13 by inflating it from the second flow channel (at this time, valves 1 and 3 are closed, and valve 2 is open). This reduces the pressure difference between the sealed chamber 13 and the inner bellows 12, preventing diesel from flowing out of the inner bellows 12 until the oil pressure data in the inner bellows 12 is restored. Subsequently, the gas circulation device enters a pressure-maintaining mode. The gas used is at room temperature. If the oil pressure data in the inner bellows 12 still has not been restored after the gas circulation device has reached the fourth threshold, it indicates that the leak sealing is not complete. At this time, the remote control module controls the diesel generator and fuel tank to shut down.

[0058] In the second application scenario, when it is necessary to defrost the waxed diesel fuel, the remote control module controls the gas circulation device to fill the sealed chamber 13 with heated gas from the second flow channel and circulate it (at this time, valve 1 is closed and valves 2 and 3 are open); the gas is a gas with temperature.

[0059] In the third application scenario, when a fire occurs, the temperature data acquired by the temperature sensor will rise. When the temperature data exceeds the second threshold, the remote control module controls the carbon dioxide fire extinguishing tank to introduce carbon dioxide gas into the sealed chamber 13 from the first flow channel (at this time, valve 1 is open, and valves 2 and 3 are closed). The carbon dioxide gas can reduce the oil temperature in the inner bellows 12, thereby reducing the oil pressure in the inner bellows 12. At the same time, the carbon dioxide gas will also be ejected from the jet holes generated by the high temperature melting on the side wall of the outer bellows 11, thereby extinguishing the fire in the area near the double-layer pipe 1.

[0060] In some embodiments, in the method of pressurizing the sealed chamber 13 by controlling the gas circulation device through the remote control module to restore the oil pressure of the inner bellows 12: when the working time of the gas circulation device exceeds a fourth threshold, the remote control module controls the diesel generator to stop working.

[0061] In this embodiment, if the oil pressure data in the inner bellows 12 does not recover after the gas circulation device has been working for a period of time, it indicates that the leak sealing has not been completed. At this time, the remote control module controls the diesel generator and fuel tank to stop.

[0062] In some embodiments, when the temperature data acquired by the temperature sensor is higher than the second threshold, the method of controlling the carbon dioxide fire extinguishing tank to introduce carbon dioxide gas into the sealed chamber 13 through the remote control module to reduce the oil temperature in the inner bellows 12 and extinguish the fire in the external environment is as follows: a plurality of air jet holes 111 are opened on the pipe wall of the outer bellows 11; a hot melt material is placed in the air jet holes 111 to seal the air jet holes 111; wherein the hot melt material melts when the temperature reaches a third threshold, and the third threshold is less than the second threshold.

[0063] In this embodiment, the hot melt material melts when the temperature reaches the third threshold, and the third threshold is less than the second threshold, in order to prevent the situation where the jet hole 111 is not open when the carbon dioxide fire extinguisher is working. If the carbon dioxide fire extinguisher starts working and the jet hole 111 is not open, the pressure in the sealed chamber 13 will increase, which will pressurize the inner bellows 12 and promote the rupture of the inner bellows 12, resulting in diesel leakage.

[0064] In some embodiments, when the temperature data acquired by the temperature sensor is higher than a second threshold, the method of controlling the carbon dioxide fire extinguishing tank to introduce carbon dioxide gas into the sealed chamber 13 to reduce the oil temperature in the inner bellows 12 and to extinguish the fire in the external environment by controlling the carbon dioxide fire extinguishing tank through the remote control module: the inner bellows 12 includes: a plurality of inner pipe sections 121 and a plurality of connecting pipe sections 122 for connecting adjacent inner pipe sections 121; the connecting pipes 122 are elastic and expand when the oil temperature in the inner bellows 12 increases to reduce the oil pressure.

[0065] In this embodiment, a flexible connecting pipe 122 is used. When the oil temperature in the inner bellows 12 increases, causing the oil pressure in the inner bellows 12 to increase, the connecting pipe 122 expands under force, thereby reducing the oil pressure in the inner bellows 12.

[0066] In some embodiments, when the temperature data acquired by the temperature sensor is higher than a second threshold, the method of controlling the carbon dioxide fire extinguishing tank to introduce carbon dioxide gas into the sealed chamber 13 through the remote control module to reduce the oil temperature in the inner bellows 12 and extinguish the fire in the external environment involves: distributing the jet holes 111 on the outer bellows 11 around the periphery of each connecting pipe 122; reducing the flow cross section of the sealed chamber 13 when the connecting pipe 122 expands, so that the jet holes 111 spray at a distance; and gradually reducing the expansion amplitude of the connecting pipe 122 after introducing carbon dioxide into the sealed chamber 13, so that the jet holes 111 spray at a nearby location.

[0067] Specifically, when the hot melt material melts, the connecting pipe 122 expands, which makes the flow channel inside the jet hole 111 smaller, that is, the flow velocity of carbon dioxide gas at that point increases, so that the carbon dioxide gas is ejected from the jet hole 111 a farther distance.

[0068] Specifically, when carbon dioxide gas comes into contact with the inner bellows 12, the carbon dioxide gas will cool the inner bellows 12, thereby reducing the oil pressure in the inner bellows 12, and thus reducing the expansion amplitude of the connecting pipe 122. That is, the flow rate of carbon dioxide gas at this point is reduced, which makes the distance of carbon dioxide gas ejected from the jet hole 111 shorter.

[0069] In this embodiment, the carbon dioxide gas ejected from the jet nozzle 111 first extinguishes the fire at a distance from the double-layer pipe 1 to form an isolation zone and prevent the fire from spreading to the double-layer pipe 1; then it gradually extinguishes the fire at a closer distance to put out any open flames that may arise near the double-layer pipe 1.

[0070] In summary, this remote fire suppression system and the diesel generator set using this system, by configuring the double-layer pipeline 1 as an outer corrugated pipe 11 and an inner corrugated pipe 12, forms a sealed chamber 13 between the outer corrugated pipe 11 and the inner corrugated pipe 12. When the sidewall of the inner corrugated pipe 12 ruptures and leaks oil, the gas circulation device is controlled to pressurize the sealed chamber 13, thereby preventing diesel fuel from flowing out of the inner corrugated pipe 12. Simultaneously, the inner corrugated pipe 12 is configured as a structure consisting of several sub-inner pipes 121 and several connecting pipes 122 for connecting adjacent sub-inner pipes 121. This allows the connecting pipes 122 to expand under pressure when the oil temperature in the inner corrugated pipe 12 rises during a fire, thereby reducing the oil pressure in the inner corrugated pipe 12. Furthermore, during a fire, carbon dioxide gas is introduced into the sealed chamber 13 by controlling a carbon dioxide fire extinguishing tank to lower the oil temperature, and carbon dioxide gas is sprayed around the double-layer pipeline 1 for fire suppression.

The working method of the remote fire protection system as described in claim 3, characterized in that, In the method of pressurizing the sealed chamber (13) by controlling the gas circulation device through the remote control module to restore the oil pressure of the inner bellows (12): When the gas circulation device operates for more than the fourth threshold time, the remote control module controls the diesel generator to stop working.

5. The working method of the remote fire protection system as described in claim 4, characterized in that, In the method of controlling the carbon dioxide fire extinguishing tank to introduce carbon dioxide gas into the sealed chamber (13) to reduce the oil temperature in the inner bellows (12) and extinguish the fire in the external environment when the temperature data obtained by the temperature sensor is higher than the second threshold, the method is as follows: Several air jet holes (111) are provided on the wall of the outer bellows (11). Hot melt material is placed inside the air vent (111) to seal the air vent (111); Among them, the hot-melt material melts when the temperature reaches the third threshold, and the third threshold is less than the second threshold.

6. The operating method of the remote fire protection system as described in claim 5, characterized in that, In the method of controlling the carbon dioxide fire extinguishing tank to introduce carbon dioxide gas into the sealed chamber (13) to reduce the oil temperature in the inner bellows (12) and extinguish the fire in the external environment when the temperature data obtained by the temperature sensor is higher than the second threshold, the method is as follows: The inner bellows (12) includes: several sub-inner tubes (121) and several connecting tubes (122) for connecting adjacent sub-inner tubes (121); The connecting pipe (122) is elastic and expands to reduce oil pressure when the oil temperature inside the inner bellows (12) rises.

7. The working method of the remote fire protection system as described in claim 6, characterized in that, In the method of controlling the carbon dioxide fire extinguishing tank to introduce carbon dioxide gas into the sealed chamber (13) to reduce the oil temperature in the inner bellows (12) and extinguish the fire in the external environment when the temperature data obtained by the temperature sensor is higher than the second threshold, the method is as follows: The air jets (111) on the outer bellows (11) are distributed around the periphery of each connecting pipe (122); When the connecting pipe (122) expands, the flow cross section of the sealed chamber (13) is reduced so that the jet hole (111) can be jetted to a distance; After carbon dioxide is introduced into the sealed chamber (13), the expansion amplitude of the connecting pipe (122) is gradually reduced so that the jet hole (111) sprays towards the nearby area.
