Description

Technical Field

[0001] This utility model relates to the field of computer room safety and environmental control technology, specifically to an emergency fan linkage control system for computer rooms. Background Technology

[0002] Modern data centers, communication equipment rooms, and power distribution rooms contain a large number of electrical devices that generate heat during continuous operation and pose a risk of electrical fires. Emergency fans are key safety equipment in such rooms, used to quickly remove smoke, harmful gases, and heat in the event of a fire or serious malfunction, buying time for personnel evacuation and equipment protection.

[0003] Because the fireproof blades are in a closed and standby state for a long time in environments such as computer rooms, the dust carried by the high-speed airflow circulation in the computer room will gradually accumulate on the fireproof blades, shafts and sealing surfaces, and mix with trace amounts of oil to form stubborn dirt. This will increase the resistance of valve operation, and may lead to slow opening, insufficient opening or even complete jamming during emergency start-up, which will seriously affect the reliability of the smoke exhaust system. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, an emergency fan linkage control system for computer rooms is provided, which solves the problem that fire dampers accumulate dust and oil due to long-term closure, causing jamming and insufficient opening during emergency start-up, thus affecting the reliability of smoke exhaust.

[0005] The purpose of this utility model is achieved by the following technical solution: a computer room emergency fan linkage control system, including a mounting shell, a protective component installed on the side of the mounting shell, a fireproof component installed inside the mounting shell, an emergency fan body installed on the back of the mounting shell, and a monitoring box electrically connected to the bottom of the mounting shell.

[0006] The protective assembly includes a protective net, a rotating shaft installed at the bottom of the protective net, a fixing block fixedly connected to the top of the protective net, a spring fixedly connected to the side of the fixing block, a wedge groove opened in the protective net, a first electric telescopic rod set at the top of the protective net, and a wedge block installed at the output end of the first electric telescopic rod. The rotating shaft is installed at the bottom of the mounting shell, and the first electric telescopic rod is fixedly connected to the mounting shell.

[0007] In one optional embodiment, the first electric telescopic rod is used to drive the wedge block to insert into or disengage from the wedge groove. When the wedge block is inserted into the wedge groove, the protective net is relatively fixed to the mounting shell, and the spring is in a compressed state.

[0008] When the wedge disengages from the wedge groove, the spring returns to its original state and pushes the protective net away from the mounting shell. The protective net forms a rotating structure with the mounting shell through the rotating shaft.

[0009] In one optional embodiment, the fireproof component includes a fireproof blade, a rotating seat fixedly connected to the end of the fireproof blade, a transmission rod movably connected to the back of the fireproof blade, and a second electric telescopic rod installed on the side of the transmission rod. The fireproof blade is rotatably connected to the inside of the mounting housing via the rotating seat, and the transmission rod is movably connected to the output end of the second electric telescopic rod.

[0010] In one alternative implementation, when the second electric telescopic rod is in operation, the transmission rod drives the fireproof blades to rotate.

[0011] In one optional embodiment, multiple fireproof blades are provided and are movably connected to multiple transmission rods, all of which are movably connected to the output end of the second electric telescopic rod.

[0012] In one optional embodiment, at least one rotating seat is provided with a torque sensor for monitoring the opening degree of the fireproof blades and generating an opening degree signal.

[0013] The torque sensor is electrically connected to the central controller, which receives the opening signal.

[0014] In one alternative implementation, the central controller is configured to shut down the computer room air conditioning system when it is determined from the opening signal that the fireproof blades are in the open state.

[0015] In one optional embodiment, the monitoring box integrates a smoke sensor, a temperature sensor, and a harmful gas sensor, and has a built-in signal conditioning circuit.

[0016] The monitoring box is connected to the central processing unit via a composite cable, which simultaneously powers the sensors inside the box and transmits monitoring signals.

[0017] Both the first and second electric telescopic poles are electrically connected to the central processing unit.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. By setting up protective components, the protective net can protect the fireproof blades, preventing dust and other impurities from adhering to the fireproof blades and avoiding jamming of the moving parts of the fireproof blades. At the same time, when it is necessary to open the fireproof blades, the protective net can be directly separated from the fireproof blades by retracting the second electric telescopic rod.

[0020] 2. This linkage control system ensures the reliability of the opening and closing of the fireproof blades and status feedback through the second electric telescopic rod and torque sensor. The added protective net actively isolates dust under normal conditions and automatically falls off in an emergency, fundamentally eliminating the risk of jamming caused by dust accumulation. The cooperation of multiple sensors, controllers and electric telescopic rods improves the response speed, action accuracy and overall reliability of the main working of the emergency fan.

For example, they can refer to a fixed connection, a connection through an intermediary, the internal connection of two elements, or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0031] Please refer to Figures 1 to 5 An emergency fan linkage control system for computer room includes a mounting shell 1, a protective component 2 installed on the side of the mounting shell 1, a fireproof component installed inside the mounting shell 1, an emergency fan body 7 installed on the back of the mounting shell 1, and a monitoring box 8 electrically connected to the bottom of the mounting shell 1.

[0032] The protective assembly 2 includes a protective net 201, a rotating shaft 202 installed at the bottom of the protective net 201, a fixing block 203 fixedly connected to the top of the protective net 201, a spring 204 fixedly connected to the side of the fixing block 203, a wedge groove 205 formed on the protective net 201, a first electric telescopic rod 206 set at the top of the protective net 201, and a wedge 207 installed at the output end of the first electric telescopic rod 206. The rotating shaft 202 is installed at the bottom of the mounting housing 1, and the first electric telescopic rod 206 is fixedly connected to the mounting housing 1. The first electric telescopic rod 206 is used to drive the wedge 207 to insert or disengage from the wedge groove 205. When the wedge 207 is inserted into the wedge groove 205, the protective net 201 is fixed relative to the mounting shell 1, and the spring 204 is in a compressed state. When the wedge 207 is disengaged from the wedge groove 205, the spring 204 returns to its original state and pushes the protective net 201 away from the mounting shell 1. The protective net 201 forms a rotating structure with the mounting shell 1 through the rotating shaft 202. The protective net 201 can protect the fireproof blade 3, preventing dust and other impurities from adhering to the fireproof blade 3 and preventing jamming of the moving parts of the fireproof blade 3. At the same time, when it is necessary to open the fireproof blade 3, the protective net 201 can be directly disengaged from the fireproof blade 3 by retracting the second electric telescopic rod 6.

[0033] Please refer to Figure 1 and Figure 5The fireproof component includes a fireproof blade 3, a rotating seat 4 fixedly connected to the end of the fireproof blade 3, a transmission rod 5 movably connected to the back of the fireproof blade 3, and a second electric telescopic rod 6 installed on the side of the transmission rod 5. The fireproof blade 3 is rotatably connected to the inside of the mounting shell 1 through the rotating seat 4. The transmission rod 5 is movably connected to the output end of the second electric telescopic rod 6. When the second electric telescopic rod 6 is working, the transmission rod 5 drives the fireproof blade 3 to rotate. There are multiple fireproof blades 3, and they are movably connected to multiple transmission rods 5. All multiple transmission rods 5 are movably connected to the output end of the second electric telescopic rod 6.

[0034] It should be noted that: through the operation of the second electric telescopic rod 6 and the transmission rod 5, the rotation of multiple fireproof blades 3 can be controlled synchronously, thereby switching between open and closed working states. When the fireproof blades 3 are in the closed state, the emergency smoke exhaust system can be completely isolated from the internal environment of the computer room, preventing dust and moisture in the daily air conditioning circulation air of the computer room from entering the smoke exhaust duct and fan, avoiding equipment corrosion and dust accumulation, and ensuring the integrity of the equipment in an emergency. When it is in the open state, a mechanical, low-resistance ventilation channel is created between the dangerous area of ​​the computer room and the safe area outdoors, guiding the high-temperature toxic smoke to flow orderly along the designed duct, rather than spreading disorderly in the computer room, creating conditions for personnel evacuation and reducing the damage of smoke to unaffected equipment.

[0035] Please refer to Figure 1 , Figure 2 and Figure 5 At least one rotating seat 4 is equipped with a torque sensor to monitor the opening degree of the fireproof blade 3 and generate an opening degree signal. The torque sensor is electrically connected to the central controller, which receives the opening degree signal. The central controller is configured to shut down the air conditioning system of the machine room when it is determined that the fireproof blade 3 is in the open state based on the opening degree signal. The monitoring box 8 integrates a smoke sensor, a temperature sensor, and a harmful gas sensor, and has a built-in signal conditioning circuit. The monitoring box 8 is connected to the central processor through a composite cable, which simultaneously powers the sensors inside the box and transmits monitoring signals. The first electric telescopic rod 206 and the second electric telescopic rod 6 are both electrically connected to the central processor. The reliability of the opening and closing of the fireproof blade 3 and the status feedback are ensured by the second electric telescopic rod 6 and the torque sensor. The added protective net 201 actively isolates dust under normal conditions and automatically falls off in an emergency, fundamentally eliminating the risk of jamming caused by dust accumulation. The cooperation of multiple sensors, controllers, and electric telescopic rods improves the response speed, action accuracy, and overall reliability of the emergency fan body 7.

[0036] Working principle: First, the monitoring box 8 is installed in a suitable location in the machine room. The sensors inside the monitoring box 8 continuously monitor the environmental data in the machine room. These signal data are transmitted to the central processing unit. The intelligent algorithm built into the central processing unit will fuse and analyze this multi-source information to determine the nature of the event. When it is necessary to start the main body of the emergency fan 7, it first controls the first electric telescopic rod 206 to retract, so that the wedge 207 disengages from the wedge groove 205. Under the action of the spring 204's own elastic force, it will push the protective net 201 to detach from the mounting shell 1. The bottom end of the protective net 201 rotates to a vertically downward position through the rotating shaft 202. Then, the central processing unit controls the second electric telescopic rod 6 to work. The output end of the electric telescopic rod 6 extends forward, causing the transmission rod 5 to push the fireproof blade 3 to rotate, thus opening it. When fully opened, it cuts off the power to the ordinary air conditioner to prevent combustion. Finally, it starts the main body of the emergency fan 7 and can adjust the fan speed through the frequency converter according to the smoke concentration fed back by the sensor. During this process, the device monitors in real time whether each actuator has completed its action accurately and in place through torque sensors, electric telescopic rods, airflow sensors, etc., and verifies whether the smoke exhaust duct is truly unobstructed and whether the fan is operating effectively. If the feedback signal is abnormal, the controller will immediately determine the fault point and activate the backup plan to ensure that the system can still play its maximum role in abnormal situations.

[0037] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations will be apparent to those skilled in the art without actually departing from the scope and spirit of the claims, such as variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.

[0038] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
