[0032] As described in the background, the operation safety of the cold storage is low, because: the air temperature in the cold storage is low (for example, lower than 0℃), when the humidity (or becomes the water content) in the gas provided to the cold storage is large, when the gas is transmitted to the cold storage, the icing phenomenon will be generated on the inner wall of the pipeline, and then the cooling medium inlet of the spray head is blocked, so that the spray head cannot normally spray water, and there is a safety hazard, when the cold storage catches fire, the best time to extinguish the fire will be missed.

[0033] In order to solve the above technical problems, the embodiment of the present application provides a fire-fighting equipment for a cold storage, comprising: a passage provided in the cold storage and providing a transmission path, the passage has a second end located in the cold storage and a first end located outside the cold storage; a gas supply device in communication with the first end of the passage and providing a gas, and the gas has a preset differential pressure; a filter device provided between the first end of the passage and the gas supply device, and filtering a specific medium in the gas; a supply device in communication with the first end of the passage and linked with the gas supply device, and providing a fire extinguishing medium; and a spray device in communication with the second end of the passage and spraying the fire extinguishing medium to the cold storage.

[0034] The fire-fighting equipment for the cold storage provided by the embodiment of the present disclosure, the gas provided by the gas supply device has a preset differential pressure, when there is a fire risk in the cold storage, the preset differential pressure of the gas will change, by linking the supply device and the gas supply device, the supply device can provide the fire extinguishing medium into the cold storage through the first end of the channel, and the first end of the channel and the gas supply device are provided with the filtering device for filtering the specific medium in the gas, so that the humidity of the gas provided into the channel can meet the use requirement, avoiding or reducing the risk of blocking the cooling medium inlet of the spraying device, and then the spraying device arranged at the second end of the channel can spray the fire extinguishing medium to the cold storage, eliminating the fire risk, so as to improve the operation safety of the cold storage.

[0035] In order to make the above-mentioned purpose, characteristics and advantages of the present application more obvious and easy to understand, the present application will be described below with reference to the accompanying drawings.

[0036] Referring to Figure 1 The structure diagram of a fire-fighting equipment for a cold storage in the embodiment of the present disclosure is shown in FIG. 1, which can include: Figure 1

[0037] The channel 110 is arranged in the cold storage 10A and provides a transmission path, the channel 110 has a second end e2 located in the cold storage 10A and a first end e1 located outside the cold storage 10A;

[0038] The gas supply device 120 is in communication with the first end e1 of the channel 110 and provides gas, and the gas has a preset differential pressure;

[0039] The filtering device 130 is arranged between the first end e1 of the channel 110 and the gas supply device 120 and filters the specific medium in the gas;

[0040] The supply device 140 is in communication with the first end e1 of the channel 110 and is linked with the gas supply device 120 and provides fire extinguishing medium;

[0041] The spraying device 150 is in communication with the second end e2 of the channel 110 and sprays the fire extinguishing medium to the cold storage 10A.

[0042] Specifically, when there is no fire in the cold storage 10A, the second end e2 and the first end e1 of the channel 110 are in communication, the gas supply device 120 can supply gas to the spraying device 150 located in the cold storage 10A through the channel 110, and the gas has a preset differential pressure, so as to maintain the pressure at the inlet of the fire extinguishing medium (such as water, foam, dry powder, etc.) of the supply device 120, so that the spraying device 150 is in a standby state.

[0043] ​By arranging a filter device 130 between the first end e1 of the channel 110 and the gas supply device 120, the filter device 130 can filter out specific media in the gas (such as water and other media with high humidity), so that the humidity of the gas output to the pipeline 110 meets the use requirements. The use requirements are: when the gas enters the cold storage 10A, under the action of the temperature difference, when the gas condenses, it will not block or will not completely block the fire extinguishing medium inlet of the spray device 150, that is, the spray device 150 can spray the fire extinguishing medium into the cold storage 10A.

[0044] When a fire occurs in the cold storage 10A, the sprinkler device 150 expands due to the heat, and the gas supply speed of the gas supply device 120 is much lower than the spraying speed of the sprinkler device 150, causing the gas pressure on the gas supply device 120 side to drop rapidly. When the differential pressure ratio of the gas is lower than the preset differential pressure ratio, the supply device 140 starts to work and fills the cooling medium into the pipeline 110, so that the sprinkler device 150 can spray the cooling medium into the cold storage 10A to extinguish the fire.

[0045] Since the humidity of the gas provided to the channel 100 can meet the use requirements, the risk of the cooling medium inlet of the spray device 150 being blocked is avoided or reduced. Therefore, the spray device 150 arranged at the second end e2 of the channel 110 can spray the fire extinguishing medium into the cold storage 10A, eliminating the fire risk, thereby improving the operation safety of the cold storage.

[0046] It should be noted that, first, Figure 1 Two of the spray devices 150 are shown. In some other embodiments, the number of the spray devices 150 can be other values. This embodiment does not impose any restrictions on the number of spray devices, and the number can be set according to actual needs. Second, the connection relationship between the various components in the figure is only an example to illustrate that the spray device 150 sprays the fire extinguishing medium through the cooperation between the filter device 130, the supply device 140 and the air supply device 120. Third, Figure 1 The positions of the second end e2 and the first end e1 of the pipeline 110 are also illustrative. It only needs that the second end e2 is located inside the cold storage 10A and the first end e1 is located outside the cold storage 10A.

[0047] In some embodiments of the present disclosure, Figure 1 , see Figure 2 The structural diagram of an air supply device in an embodiment of the present disclosure is shown in FIG. Figure 2 As shown, the air supply device 120 may include:

[0048] A gas supply mechanism 121 is provided for providing the gas, wherein the gas outlet side of the gas supply mechanism 121 is connected to one side of the filter device 130;

[0049] A gas pressure maintaining mechanism 122 is in communication with the other side of the filtering device 130 and the first end e1 of the channel 110 respectively, and maintains the pressure of the gas so that the gas has the preset differential ratio pressure.

[0050] Specifically, the filtering device 130 is arranged between the gas supply mechanism 121 and the gas pressure maintaining mechanism 122, so that the humidity of the gas flowing into the gas pressure maintaining mechanism 122 is low, which can reduce the influence of the humidity in the gas on the gas pressure maintaining mechanism 122.

[0051] In some embodiments of the present disclosure, the gas supply mechanism 121 can include an air compressor, which has the characteristic of continuously providing compressed gas, which can meet the continuous demand of the fire-fighting equipment for the gas source and improve the stability of the gas supply.

[0052] In this case, a connecting pipe (for example, a PU pipe) is used to connect the air compressor and the filtering device. On the one hand, the connecting pipe can be used as a buffer between the air compressor and the filtering device to reduce the influence of the vibration and impact generated by the operation of the air compressor on the filtering device and improve the operation stability of the filtering device. On the other hand, the connecting pipe has higher flexibility, which makes the air compressor and the filtering device better in installation and disassembly.

[0053] In some other embodiments, a gas pipe quick connector can be used to connect the air compressor and the filtering device, so that the connection and separation between the pipeline and the filtering device can be realized through a simple plug-in operation.

[0054] Furthermore, the fire-fighting equipment can further include an anti-fog film attached to the inner wall of the connecting pipe. When the gas flows through the connecting pipe and contacts the anti-fog film, the anti-fog film can absorb part of the water vapor in the gas in advance to reduce the humidity of the gas, which can reduce the requirement for the filtering device. In the case that the filtering performance of the filtering device is poor, the humidity of the gas can still meet the use requirement.

[0055] In some optional embodiments of the present disclosure, to increase the contact area of the gas and the anti-fog film, the fire-fighting equipment can further include an anti-fog film arranged in a direction perpendicular to the inner wall of the connecting pipe and having holes.

[0056] Specifically, the anti-fog film is arranged in a direction perpendicular to the flow direction of the gas (the flow direction can be approximately along the direction from the inlet to the outlet of the connecting pipe), so that the anti-fog film can occupy most of the space of the inner diameter of the connecting pipe. Therefore, when the gas flows through the anti-fog film, part of the gas directly flows to the gas pressure maintaining mechanism through the holes of the anti-fog film, and part of the gas directly contacts the anti-fog film and then flows to the gas pressure maintaining mechanism through the holes of the anti-fog film to reduce the humidity of the gas.

[0057] It can be understood that, first, in actual application scenarios, an anti-fog film attached to the inner wall and an anti-fog film arranged in a direction perpendicular to the inner wall of the connecting pipe can be set in the connecting pipe at the same time; second, the anti-fog film arranged in a direction perpendicular to the inner wall of the connecting pipe can be multiple, and the anti-fog film can be located at the inlet, outlet, and any position between the inlet and outlet of the connecting pipe; third, the setting position of the anti-fog film needs to meet the following requirements: it does not affect the transmission of the cooling medium.

[0058] In some embodiments of the present disclosure, an air pressure maintenance mechanism is used in the pre-action system of a fire protection system to control flow and pressure by adjusting valves, thereby maintaining stable air pressure within the system. The air pressure maintenance mechanism may be composed of a pressure sensor, an actuator, a control valve, and a controller.

[0059] Specifically, when the air pressure in the pipeline is lower than the set value, the air pressure maintaining mechanism will automatically open the valve to increase the air pressure in the pipeline by increasing the flow rate; when the air pressure is higher than the set value, the air pressure maintaining mechanism will close the valve to limit the flow rate, thereby reducing the air pressure in the pipeline and keeping the differential pressure ratio of the gas in the pipeline stable.

[0060] In some embodiments of the present disclosure, the filtering device may include a water-gas separator to separate gas and liquid, improve the dryness of the gas, and reduce the phenomenon of water in the gas.

[0061] More specifically, the water-gas separator has a filter element. When the gas flows through the filter element, the filter element can absorb the liquid in the gas and allow the gas to pass through, which can reduce the humidity of the gas.

[0062] It should be noted that when a water-gas separator with a filter element is used, the filter element can be cleaned or replaced regularly to ensure that the filter element has good adsorption capacity.

[0063] In some embodiments of the present disclosure, the gas supply mechanism includes a gasification facility CDA. The gas provided by the gasification facility CDA has low humidity and may even be dry gas, which can reduce the requirements for the filtering device.

[0064] Correspondingly, the fire-fighting equipment may also include: a switch arranged between the gasification facility CDA and the gas pressure maintaining mechanism, for opening and closing the gas transmission path, so that when a fire occurs, the switch can be placed in an off state, cutting off the gas supply, so that the path between the gas and the channel is in an off state, and the channel can be filled with fire-extinguishing medium, thereby shortening the fire-extinguishing time.

[0065] In some embodiments of the present disclosure, the switch may include a solenoid valve, so that the switch can be quickly opened and closed by remote control to reduce the on-off delay of the switch.

[0066] In some other embodiments, the switch may also be any device or apparatus with switching capability, such as a pneumatic valve, a button, or a photoelectric switch.

[0067] In some optional embodiments of the present disclosure, in order to further reduce the risk of the cooling medium inlet of the spray device being blocked, some heat-insulating media may be provided on the pipeline.

[0068] More specifically, the fire-fighting equipment for the cold storage may further include: a heat-insulating device arranged at least along the circumference of the passage in the cold storage to reduce the temperature in the passage.

[0069] By arranging a heat preservation device at least along the circumference of the channel in the cold storage, the temperature difference between the channel inside the cold storage and the channel outside the cold storage can be reduced, and the probability of gas condensation or even sublimation into ice-like substances can be reduced, thereby keeping the cooling medium inlet of the spray device unobstructed.

[0070] In some embodiments of the present disclosure, the heat preservation device may include: at least one of heat preservation cotton, aluminum sheet and heating tape.

[0071] For example, see Figure 3 The schematic diagram of the relative position relationship between a heat preservation device and a channel in an embodiment of the present disclosure is shown in FIG. Figure 3 As shown, the heat preservation device includes heat preservation cotton HT and aluminum skin AS, and the aluminum skin AS is arranged (for example, attached) on the outer surface of the channel 110, and the heat preservation cotton HT covers the aluminum skin AS.

[0072] In some optional embodiments, the aluminum sheet AS can also be attached to a portion (eg Figure 3 ) or located in the passage outside the cold storage, which can further reduce the probability of gas condensation or even sublimation into ice-like substances.

[0073] See also, for example, Figure 4 The diagram shown is a schematic diagram of the relative position relationship between another heat preservation device and the channel in an embodiment of the present disclosure. When the heat preservation device includes a heating tape EH, the fire-fighting equipment further includes: a controller C electrically connected to the heating tape.

[0074] It should be noted that Figure 3 and Figure 4 The relative position relationship between the insulation device and the channel is shown for illustration only, and is used to indicate that at least one insulation device selected from insulation cotton HT, aluminum sheet AS and heating tape EH is provided on the outer surface of the channel to reduce the temperature difference at different positions in the channel.

[0075] It can be understood that the above examples are only illustrative, and in actual applications, those skilled in the art can adaptively select and / or deform the cooling device provided by the embodiments of the present disclosure according to actual needs and application scenarios. For example, the number of some components in the cooling device is changed; for another example, some components in the cooling device are replaced equally, etc. Based on this, more implementation schemes of the cooling device can be extended, and the embodiments of the present disclosure do not limit these extended schemes.

It should be known that the content of the cold storage system described below can be mutually corresponding to the content of the fire-fighting device for cold storage described above.

[0078] Among them, the specific content of the structure, connection relationship, function, working principle and the like of the fire-fighting device can refer to the description and drawings in the above related parts, and will not be repeated here.

[0079] By adopting the cold storage system with the above fire-fighting device, when a fire occurs in the cold storage, the fire-fighting device can normally spray the cooling medium to the cold storage, so as to timely extinguish the ignition point.

[0080] Although the embodiments of the present disclosure are disclosed as above, the utility model is not limited thereto.
