Abstract
Description
Technical Field
[0001] This utility model belongs to the field of detection technology and relates to a smoke detection device for data centers. Background Technology
[0002] Data centers are buildings that provide an operating environment for centrally located electronic information equipment. They centrally store, compute, and exchange data, and are the core infrastructure underlying cloud computing. Because data centers have numerous cables, some cables or equipment may overheat and short-circuit. These situations can generate smoke, potentially leading to fires. Therefore, it is essential to design a smoke detection device for data centers to promptly detect and protect against smoke. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a smoke detection device for data centers.
[0004] The objective of this utility model can be achieved through the following technical solution: A smoke detection device for data centers, comprising a housing body, characterized in that the upper part of the housing body is an air outlet, the lower part of the housing body is an air inlet, the interior of the housing body is divided into three annular channels: an outer ring channel, a middle layer channel, and an inner ring channel, smoke sensors and gas sensors are installed sequentially from the outside to the inside in the outer ring channel and the inner ring channel, the middle layer channel is only equipped with a smoke sensor, openings are provided between the outer ring channel, the inner ring channel and the middle layer channel, the outlets of the outer ring channel and the inner ring channel are provided with several circular openings, and electrically controlled valves are installed at the circular openings, a flame detector is installed at the center of the bottom of the housing body, and a main control device is installed at the center of the interior of the housing body.
[0005] The working principle of this utility model is as follows: Connect the top air outlet of this smoke detection device to the air inlet of the ventilation duct of the external data center to complete the installation; in the default state, the electronically controlled valve is closed. After the air enters the outer ring channel, the middle layer channel, and the inner ring channel, it is first detected by the smoke sensor. If normal, it is collected in the middle layer channel through the opening and then led out to the air outlet. If the smoke sensor detects an abnormality, the electronically controlled valve is opened, allowing some air to be led out through the circular openings of the outer ring channel and the inner ring channel. When this part of the air passes through the outer ring channel and the inner ring channel, it will pass through the gas sensor. The gas sensor detects the volatile organic compounds released by the overheated circuit as an auxiliary criterion for smoke judgment; during this period, the flame detector works continuously to detect whether there is an open flame; the smoke sensor, gas sensor, and flame detector are all controlled by the main control device, and the detection results are remotely transmitted to the background.
[0006] The smoke sensors in the outer ring channel, middle layer channel, and inner ring channel are installed at different horizontal heights.
[0007] The above structure, with its staggered arrangement, increases detection accuracy.
[0008] The outer ring channel has more circular openings than the inner ring channel.
[0009] The above structure is adapted to airflow.
[0010] The flame detector is connected to a rotary motor at the top, which is installed inside the outer casing.
[0011] By adopting the above structure, the flame detector is continuously rotated at a low speed by a rotary motor, thereby increasing the detection range.
[0012] Dustproof nets are installed at the air inlets of the outer ring channel, middle layer channel, and inner ring channel.
[0013] The above structure prevents ordinary dust from entering through the dustproof mesh.
[0014] Compared with existing technologies, this smoke detection device for data centers has the following advantages: by setting up a multi-channel detection structure and cooperating with various types of detectors, this utility model can detect smoke more accurately. Attached Figure Description

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0020] like Figure 1-3As shown, the smoke detection device for this data center includes a main body 1. The upper part of the main body 1 is an air outlet, and the lower part of the main body 1 is an air inlet. The interior of the main body 1 is divided into three annular channels: an outer channel 2, a middle channel 3, and an inner channel 4. Smoke sensors 5 and gas sensors 6 are installed sequentially from the outside to the inside in the outer channel 2 and the inner channel 4. Only smoke sensors 5 are installed in the middle channel 3. Openings 7 are provided between the outer channel 2, the inner channel 4 and the middle channel 3. Several circular openings 8 are provided at the outlets of the outer channel 2 and the inner channel 4. Electrically controlled valves 9 are installed at the circular openings 8. A flame detector 10 is installed at the center of the bottom of the main body 1. A main control device 11 is installed at the center of the interior of the main body 1.
[0021] In this invention, the smoke sensor 5 adopts the existing laser scattering smoke sensor 5, which has a faster response speed and better detection effect compared with traditional smoke detectors.
[0022] In this invention, the gas sensor 6 adopts an existing PID gas detector, which has high sensitivity and can detect volatile organic compounds in a timely manner to assist in judgment.
[0023] In this invention, the flame detector 10 adopts the existing dual-band infrared flame detector 10.
[0024] In this invention, the number of sensors in the outer ring channel 2, middle layer channel 3, and inner ring channel 4 is installed according to actual needs to increase fault tolerance and error.
[0025] In this utility model, the electrically controlled valve 9 adopts an existing gas valve.
[0026] The smoke sensors 5 in the outer ring channel 2, middle layer channel 3, and inner ring channel 4 are installed at different horizontal heights.
[0027] The number of circular openings 8 in the outer ring channel 2 is greater than that in the inner ring channel 4.
[0028] A rotary motor 12 is connected to the top of the flame detector 10, and the rotary motor 12 is installed inside the housing body 1.
[0029] Dustproof nets 13 are installed at the air inlets of the outer ring channel 2, the middle layer channel 3, and the inner ring channel 4.
[0030] The working principle of this utility model is as follows: The top air outlet of this smoke detection device is connected to the air inlet of the ventilation duct of an external data center to complete the installation. In the default state, the electronically controlled valve 9 is closed. After the air enters the outer ring channel 2, the middle layer channel 3, and the inner ring channel 4, it is first detected by the smoke sensor 5. If it is normal, it is collected in the middle layer channel 3 through the opening 7 and then discharged to the air outlet. If the smoke sensor 5 detects an abnormality, the electronically controlled valve 9 is opened, allowing some air to be discharged through the circular openings 8 of the outer ring channel 2 and the inner ring channel 4. When this part of the air passes through the outer ring channel 2 and the inner ring channel 4, it will pass through the gas sensor 6. The gas sensor 6 detects the volatile organic compounds released by the overheated circuit as an auxiliary criterion for smoke detection. During this period, the flame detector 10 continues to work to detect whether there is an open flame. The smoke sensor 5, the gas sensor 6, and the flame detector 10 are all controlled by the main control device 11, and the detection results are remotely transmitted to the background.
[0031] In this invention, the various mechanisms are connected and driven by existing technologies, and synchronous control is achieved through the main control device 11.
