[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the utility model, and is not used to limit the utility model.

[0024] It should be noted that the orientations or positional relationships indicated by various orientation terms are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0025] In addition, the terms "first", "second", etc. in the specification and claims of the utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence; and, in the absence of conflict, the embodiments of the utility model and the features in the embodiments can be arbitrarily combined with each other. It should be understood by those of ordinary skill in the art that the diagrams provided herein are for illustrative purposes, and the diagrams are not necessarily drawn to scale. It should be understood that when an element is said to be "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or there can be an intermediate element.

[0026] In order to solve the problem in the prior art that the communication room loses its cold source due to air conditioning failure, city power outage, etc., resulting in high-temperature shutdown of communication equipment in the room, the utility model provides a mobile communication room emergency disaster prevention solution, which can realize emergency delivery of cold energy to the communication room to achieve the effect of emergency disaster prevention, which is described in detail below through specific embodiments.

[0027] like Figures 1 to 3 As shown, the emergency disaster prevention device for the communication room includes: a hollow box 9, a fan 3 located in the box 9, a controller 4 electrically connected to the fan 3, and a retractable air supply duct 6 connected to the side of the box 9.

[0028] It should be noted that the side of the box body 9 needs to be provided with ventilation holes that match the diameter of the retractable air supply pipe 6. The retractable air supply pipe 6 is in a retracted state when not in use and in a stretched state when in use. Figures 1 to 3 The retractable air supply duct is only schematically drawn, and its length when in use is not shown. Its length when in use can be set according to actual needs.

[0029] Among them, the box body 9 is located in the low temperature area (i.e., area A in the figure), the retractable air supply pipe 6 extends from the low temperature area to the high temperature area in the communication room (i.e., area B in the figure), and the air outlet is located in the high temperature area, and the temperature of the high temperature area is higher than the temperature of the low temperature area.

[0030] Furthermore, the low temperature area is located outdoors, or the low temperature area is a low temperature area in a communication room. If the outdoors are used as a "low temperature area", emergency delivery of outdoor cooling to the communication room can be achieved, thereby achieving an emergency disaster prevention effect; if the low temperature area in the communication room is used as a "low temperature area", automatic cooling balance in the communication room can be achieved, thereby achieving an emergency disaster prevention effect.

[0031] Since a large number of communication equipment are placed in the communication room, if the cold source is lost due to air conditioning failure, power outage, etc., some areas in the communication room will become abnormally high temperature. Generally, the outdoor temperature will be lower than the abnormally high temperature. Therefore, the area with abnormally high temperature in the communication room is called "high temperature area", and the appropriate outdoor area or the other areas with lower temperature in the communication room are called "low temperature area". The high temperature area, low temperature area and appropriate outdoor area in the communication room can be specifically defined by those skilled in the art according to the actual situation.

[0032] The controller 4 is used to control the start and stop of the fan 3. After starting, the fan 3 is used to transport air from the low-temperature area to the high-temperature area in the communication room through the retractable air supply pipe 3, thereby transporting the cold energy in the low-temperature area to the high-temperature area, so as to achieve the purpose of quickly cooling the high-temperature area in the communication room.

[0033] Furthermore, the fan 3 may be a centrifugal fan; the retractable air supply duct 6 may be a retractable flame-retardant air supply duct.

[0034] In this embodiment, the cold energy in the low-temperature area of ​​the communication room or the outdoor cold energy can be quickly transported in a large-span emergency through the retractable air supply duct, thereby suppressing the local temperature increase in the communication room, effectively responding to sudden high temperature conditions in the communication room, and realizing emergency disaster prevention in the communication room.

[0035] In a specific embodiment, Figure 1 As shown, the emergency disaster prevention device for the communication room further includes: a temperature sensor 2 electrically connected to the controller 4. The temperature sensor 2 can be arranged at a suitable position on the outer surface of the box 9, for example, it can be arranged on the top of the box 9.

[0036] The temperature sensor 2 is used to collect the temperature data of the low temperature area and send the temperature data of the low temperature area to the controller 4. The controller 4 is used to determine whether the low temperature area meets the preset cold delivery conditions according to the temperature data of the low temperature area. If the low temperature area meets the preset cold delivery conditions, the fan 3 is controlled to start; if the low temperature area does not meet the preset cold delivery conditions, or the air conditioning refrigeration of the high temperature area in the communication room is restored, the fan 3 is controlled to stop.

[0037] In this embodiment, the fan is started only when the low-temperature area meets the preset cold transport conditions to quickly transport the cold from the low-temperature area to the high-temperature area. On the one hand, it can ensure sufficient cold capacity to cool down the high-temperature area in the communication room as soon as possible. On the other hand, if the low-temperature area is a low-temperature area in the communication room, it can avoid the risk of high temperature in the original low-temperature area in the communication room due to excessive cold transport.

[0038] Of course, if the current low-temperature area does not meet the cold transport conditions, the entire communication room emergency disaster prevention device can be moved to another low-temperature area that meets the cold transport conditions to meet the cold demand.

[0039] In a specific embodiment, if the temperature value of the low temperature area is less than a preset temperature limit, the low temperature area meets the preset cold transport condition; if the temperature value of the low temperature area is greater than or equal to the preset temperature limit, the low temperature area does not meet the preset cold transport condition.

[0040] In this embodiment, if the low-temperature area is a low-temperature area in a communication room, in order to prevent the original low-temperature area in the communication room from causing high temperature risks due to excessive cold delivery, a safety temperature value of the low-temperature area can be set in advance, and the preset temperature limit is not higher than the preset safety temperature value of the low-temperature area, so as to ensure that the temperature of the low-temperature area will not exceed the preset safety temperature value even if it rises after the fan is turned on.

[0041] like Figure 1 and Figure 3 As shown, the emergency disaster prevention device for the communication room further includes: a frequency converter 5 which is electrically connected to the controller 4 and the fan 3 and is connected to a power supply.

[0042] The controller 4 is also used to obtain temperature data of the high temperature area in the communication room, and obtain the temperature difference between the low temperature area and the high temperature area in the communication room based on the temperature data, and adjust the speed of the fan 3 through the inverter 5 based on the temperature difference.

[0043] At present, in order to monitor the real-time temperature in the communication room, a number of temperature sensors are generally installed at appropriate locations in the communication room. The controller can obtain the real-time temperature data of the high-temperature area in the communication room from the temperature sensors installed in the high-temperature area in the communication room (for example, transmit the temperature data to the controller through wireless transmission methods such as Bluetooth and WiFi), or the real-time temperature value of the high-temperature area in the communication room can be manually input into the controller.

[0044] In this embodiment, the power frequency of the fan connected to the power supply is adjusted based on the temperature difference between the low-temperature area and the high-temperature area, thereby adjusting the fan speed and further controlling the speed of cold delivery, which can achieve rapid cooling of the high-temperature area and achieve energy-saving effects.

[0045] Furthermore, the controller 4 is specifically used to adjust the rotation speed of the fan 3 so that the temperature difference between the low-temperature area and the high-temperature area is proportional to the rotation speed of the fan 3, so that the fan speed is relatively fast in the early stage, and as the temperature difference between the low-temperature area and the high-temperature area gradually decreases, the rotation speed of the fan 3 gradually slows down until the temperature difference between the two approaches zero, and the rotation speed of the fan 3 enters a stable period. Such adjustment can not only realize the rapid delivery of cold, but also is beneficial to energy saving.

[0046] In a specific embodiment, the fan 3 is specifically used to start and run at a low speed after being connected to the power supply, and to officially run under the control of the controller 4 after the preset cold delivery conditions are met in the low-temperature area. Among them, the speed of the fan "running at a low speed" is common knowledge; the speed of "running at a formal speed" can be set according to the temperature difference between the low-temperature area and the high-temperature area, and of course, it can also be set and adjusted by those skilled in the art according to actual needs.

[0047] In this embodiment, the fan first runs at a low speed after being connected to the power supply in order to avoid a large current shock at the moment of startup and to save energy. Then, the fan officially runs after the controller determines that the low-temperature area meets the preset cold delivery conditions to provide cold air to the high-temperature area on demand.

[0048] In a specific embodiment, Figures 1 to 3 As shown, a detachable dust filter 8 is provided on the other side of the box body 9, and the dust filter 8 is arranged opposite to the air inlet of the telescopic air supply pipe 6. It should be noted that a ventilation hole matching the size of the dust filter 8 needs to be provided on the other side of the box body 9.

[0049] In this embodiment, the detachable dust filter can remove dust and purify the air during emergency outdoor cold delivery.

[0050] In a specific embodiment, Figure 2 and Figure 3 As shown, a plurality of universal wheels 7 are provided at the bottom of the box body 9 .

[0051] The universal wheels can be evenly distributed at the bottom of the box. For example, four universal wheels can be used and arranged near the four corners of the bottom of the box, so that the communication room emergency disaster prevention device is a movable room disaster recovery equipment with the characteristics of flexibility, speed, safety and convenience.

[0052] Combine the following Figures 1 to 3 Describe the structural composition and working principle of the emergency disaster prevention device in the communication room.

[0053] 1)Structural composition:

[0054] Power access terminal 1, function: fan AC power input.

[0055] Temperature sensor 2, function: detect the temperature in the low temperature area.

[0056] The fan 3 is a centrifugal fan, and its function is to deliver cold air. The centrifugal fan can effectively extract air and is suitable for ducted air supply. Compared with the axial flow fan, the centrifugal fan has the advantages of low noise, stable operation, high wind pressure, large air volume and long air supply distance.

[0057] Controller 4, function: control the start / stop of the fan. When the temperature in the low-temperature area meets the cold transport conditions, the fan starts; when the temperature in the low-temperature area does not meet the cold transport conditions, the fan stops.

[0058] Inverter 5, function: adjust the power frequency of the fan connected to the power supply according to the temperature difference between the low temperature area and the high temperature area, thereby adjusting the fan frequency and further adjusting the air supply volume.

[0059] The retractable air supply duct 6 is specifically a retractable flame-retardant air supply duct, which has the function of serving as a cold air delivery channel, is made of flame-retardant material, has a retractable length, and has good space utilization.

[0060] The universal wheel 7, as a sliding roller, has the following functions: flexible and movable, convenient for transportation and emergency rescue.

[0061] The dust filter 8 is detachably connected to the box body, and its function is to remove dust and purify the air during emergency delivery of outdoor cooling capacity.

[0062] Box 9, function: to load the fan and install the retractable air supply duct.

[0063] 2) Working principle:

[0064] "Area A" is the low-temperature area and the cooling output side; "Area B" is the high-temperature area in the computer room and the cooling receiving side.

[0065] (1) The box body 9 is placed in the "A region", and the telescopic air supply pipe 6 is stretched so that its air outlet is placed in the "B region".

[0066] (2) The AC power supply is connected to the centrifugal fan 3 through the power supply terminal 1, and the centrifugal fan 3 is turned on to run at a low speed. The temperature sensor 2 detects the temperature data of the air inlet side of the low-temperature area and uploads it to the controller 4. The controller 4 determines whether the temperature value of the low-temperature area meets the cold transport condition (the temperature value of the low-temperature area is less than the temperature limit value, which meets the cold transport condition; the temperature value of the low-temperature area is greater than or equal to the temperature limit value, which does not meet the cold transport condition, and the temperature limit value is not higher than the safety temperature of the low-temperature area).

[0067] (3) When the temperature value of "Area A" meets the cold transport condition, the centrifugal fan 2 is officially put into operation. The speed is adjusted by the controller 4 according to the temperature difference between the low-temperature area and the high-temperature area. The frequency converter 5 is adjusted to achieve proportional control of the temperature difference and the fan speed. If the temperature of "Area A" reaches the preset safety temperature value, the fan stops (to avoid the risk of high temperature in the low-temperature area due to excessive cold transport).

[0068] (4) The temperature value of “Area A” does not meet the cooling capacity delivery condition, and centrifugal fan 3 stops running.

[0069] (5) The air conditioning and refrigeration in “Area B” is restored, the emergency disaster prevention device completes the cooling disaster backup task, and centrifugal fan 3 stops running.

[0070] The communication room emergency disaster prevention device provided by the embodiment of the utility model is composed of a temperature sensor, a centrifugal fan, a controller, a frequency converter, a universal wheel, a dust filter and a retractable flame-retardant air supply duct. The technical core is to automatically calculate the temperature difference between the low-temperature area and the high-temperature area through temperature detection in the low-temperature area and the controller, and adjust the frequency converter to achieve proportional control of the temperature difference and the fan speed. The cold capacity in the low-temperature area of ​​the communication room or the outdoor cold capacity can be quickly transported to the communication room through the retractable flame-retardant air supply duct for large-span emergency cold capacity delivery, which effectively responds to local sudden high temperature situations. At the same time, the cold capacity delivery speed is controlled according to the temperature difference to avoid high temperature risks caused by excessive cold capacity delivery in the low-temperature area, and the automatic balance of cold capacity in the room and the emergency delivery control of outdoor cold capacity are achieved, so as to achieve the effect of emergency disaster prevention. The device adopts a centrifugal blower, equipped with universal wheels, a detachable dust filter and a retractable flame-retardant air supply duct. It has the advantages of low noise, long air supply distance, flexible movement, dust removal and filtration. It is widely used in communication rooms where sudden high temperatures occur after local or large-scale cold sources are lost due to power outages, air-conditioning equipment failures, etc. It can effectively ensure the safety of communication rooms and can also be used to solve local hot spots in the room.
