Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically, to a fire protection equipment status monitoring sensor. Background Technology

[0002] Fire equipment status monitoring sensors are devices used to monitor the status of fire equipment in real time. They can promptly detect faults and abnormalities in fire equipment, improving the reliability and effectiveness of the fire protection system. The sensors are usually connected to the fire monitoring system and transmit the monitored data to the control center so that staff can understand the status of the fire equipment in a timely manner and take appropriate measures.

[0003] Utility model patent CN220137343U discloses a power supply monitoring sensor for fire-fighting equipment. This patent solves the problem in existing technologies where dust accumulates on the sensor, causing it to lose sensitivity and preventing timely monitoring of voltage, undervoltage protection, phase loss, and phase reversal, thus affecting its normal operation. The fire-fighting equipment power supply monitoring sensor includes an outer frame, with the sensor installed inside. The top of the outer frame is open, and a filter plate is slidably connected to the upper inner side of the frame. A filter screen is installed on the side wall of the outer frame, and a side plate is fixedly connected to one side of the frame. The proposed method, through the filter plate and filter screen, ensures sensor cleanliness while maintaining ventilation, protecting the sensor from dust interference, and simultaneously ensuring proper ventilation and heat dissipation.

[0004] Although the power supply monitoring sensor for fire-fighting equipment is easy to clean of dust, it still has the following problems in practical use: the monitoring application is limited, only able to monitor the power supply and sensor operation of the fire-fighting equipment itself, and it is difficult to monitor abnormal conditions such as real-time water pressure in fire-fighting pipelines, harmful gases in the air, and the opening and closing status of fire cabinet doors. Therefore, we propose a fire-fighting equipment status monitoring sensor. Utility Model Content

[0005] In view of the shortcomings or deficiencies of the existing technology in terms of its limited applicability, it is desirable to provide a fire equipment status monitoring sensor.

[0006] In a first aspect, this application provides a fire equipment status monitoring sensor, including a fire pipeline and a matching fire cabinet. A housing is fixedly installed on the fire pipeline. The bottom of the housing is open and a filter plate is slidably inserted into the opening. The front side wall of the housing away from the fire pipeline is open and a door is hinged inside the opening. A water pressure sensor for monitoring the water pressure inside the fire pipeline is fixedly installed on the rear inner side wall of the housing. A displacement sensor for monitoring the opening and closing status of the fire cabinet door is fixedly installed on the top of the fire cabinet. A smoke sensor is fixedly installed on the top surface inside the housing. A microcontroller for receiving signals from the water pressure sensor, displacement sensor, and smoke sensor is fixedly installed on one side wall inside the housing. An audible and visual alarm is fixedly installed on one side wall outside the housing.

[0007] According to the technical solution provided in the embodiments of this application, the probe of the water pressure sensor passes through the side wall of the housing and the fire pipe in sequence and extends into the interior of the fire pipe;

[0008] In this setup, a probe is inserted into the fire hydrant pipe to monitor water pressure data in real time. The water pressure sensor's measurement threshold is 0.3MPa~1.6MPa.

[0009] According to the technical solution provided in the embodiments of this application, an opening is provided on the door and a filter screen is fixedly installed inside the opening. The filtration accuracy of the filter plate and the filter screen is 1μm~10μm for filtering dust.

[0013] According to the technical solution provided in the embodiments of this application, the vertical distance between the smoke sensor and the roof is less than 30cm, and the smoke sensor can withstand temperatures higher than 85℃.

[0014] In this setup, the smoke sensor is positioned high for easy smoke detection, and its high-temperature resistance ensures that the smoke sensor will not cause false alarms or damage due to high temperatures.

[0015] According to the technical solution provided in the embodiments of this application, the microcontroller is provided with a heat insulation layer, and the normal operating temperature range of the microcontroller is -20℃ to 70℃.

[0018] In this setup, the exhaust fan draws in air filtered by the filter screen and filter plate and directs it to the sensing element of the smoke sensor, while the air outlet exhausts air from inside the chamber, ensuring stable air pressure inside the chamber.

[0019] According to the technical solution provided in the embodiments of this application, a multi-channel regulated power supply is fixedly installed on the outer wall of the box. The multi-channel regulated power supply is electrically connected to a water pressure sensor, a displacement sensor, a smoke sensor, an exhaust fan, a microcontroller, and an audible and visual alarm through wires.

[0037] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Please see Figures 1-5 A fire equipment status monitoring sensor includes a fire pipeline 1 and a matching fire cabinet 2. A box 3 is fixedly installed on the fire pipeline 1. The bottom of the box 3 is open and a filter plate 31 is slidably inserted into the opening. The front side wall of the box 3 away from the fire pipeline 1 is open and a door 32 is hinged inside the opening. A water pressure sensor 4 for monitoring the water pressure inside the fire pipeline 1 is fixedly installed on the rear inner side wall of the box 3. A displacement sensor 5 for monitoring the opening and closing status of the fire cabinet 2 door is fixedly installed on the top of the fire cabinet 2. A smoke sensor 6 is fixedly installed on the top surface inside the box 3. A microcontroller 7 for receiving signals from the water pressure sensor 4, the displacement sensor 5 and the smoke sensor 6 is fixedly installed on one side wall inside the box 3. An audible and visual alarm 8 is fixedly installed on one side wall outside the box 3.

[0040] In this embodiment, as Figure 2 As shown, the probe of the water pressure sensor 4 passes through the side wall of the housing 3 and the fire pipe 1 in sequence and extends into the interior of the fire pipe 1. The probe of the water pressure sensor 4 penetrates the side wall of the housing 3 and the fire pipe 1 and directly contacts the water flow to ensure real-time data.

[0041] Furthermore, such as Figure 3As shown, an opening is provided on the door 32 and a filter screen 33 is fixedly installed inside the opening. The filtration accuracy of both the filter plate 31 and the filter screen 33 is 1μm~10μm, which is used to filter dust. Dust particles in the air are generally larger than 10μm, while harmful smoke particles are generally smaller than 1μm. Therefore, the filter plate 31 and the filter screen 33 with a filtration accuracy of 1μm~10μm can effectively filter out dust in the air and ensure that harmful smoke particles are detected by the smoke sensor 6.

[0042] In this embodiment, as Figure 1 As shown, the displacement sensor 5 is fixedly installed on the top surface of the fire cabinet 2. The sensing element of the displacement sensor 5 is installed on the door frame and the edge of the door of the fire cabinet 2. The distance trigger threshold set by the displacement sensor 5 is preferably 5mm~10mm. When this threshold is exceeded, the displacement sensor 5 will transmit the abnormal signal to the microcontroller 7.

[0043] Furthermore, such as Figure 3 As shown, the vertical distance between the smoke sensor 6 and the roof is less than 30cm, and the smoke sensor 6 can withstand temperatures above 85℃. Harmful smoke generally diffuses upwards, and the smoke sensor 6 being located at a height close to the roof can improve the detection sensitivity. In addition, the temperature of harmful smoke is high when a fire occurs, and the high-temperature resistance can avoid false alarms or component damage due to high temperatures.

[0044] Furthermore, such as Figure 3 As shown, the microcontroller 7 is covered with a heat insulation layer. The normal operating temperature range of the microcontroller 7 is -20℃ to 70℃. In the event of a fire, the ambient temperature will rise rapidly. The heat insulation layer can protect the microcontroller 7 from the effects of high temperature and ensure that the microcontroller 7 can alarm normally.

[0045] In this embodiment, as Figure 3 and Figure 5 As shown, two exhaust fans 34 are preferably fixedly installed on the inner rear wall of the housing 3. The rear wall of the housing 3 has an air outlet 36 corresponding to the exhaust fan 34. A dustproof net is installed inside the air outlet 36 to prevent dust from entering. The exhaust fan 34 draws outside air to the sensing element of the smoke sensor 6 for monitoring, and exhausts the air inside the housing 3 through the air outlet 36 to ensure stable air pressure. In the event of a fire, the exhaust fan 34 and the air outlet 36 can work together to promote airflow and prevent high temperature from accumulating inside the housing 3.

[0046] It is worth mentioning that, such as Figure 3As shown, a multi-channel regulated power supply 35 is fixedly installed on the outer wall of the housing 3. The multi-channel regulated power supply 35 is electrically connected to the water pressure sensor 4, displacement sensor 5, smoke sensor 6, exhaust fan 34, microcontroller 7, and audible and visual alarm 8 through wires. The microcontroller 7 is connected to the water pressure sensor 4, displacement sensor 5, smoke sensor 6, and audible and visual alarm 8 through signal lines. The wires enable each sensor and the multi-channel regulated power supply 35 to be electrically connected in the same way, stabilizing the voltage output to adapt to fluctuating environments. The signal connection between the microcontroller 7 and each sensor plays the role of data acquisition, analysis and processing, decision control, and communication coordination.

[0047] Finally, it should be noted that the components involved in this utility model, such as the exhaust fan 34, multi-channel regulated power supply 35, water pressure sensor 4, displacement sensor 5, smoke sensor 6, microcontroller 7, and audible and visual alarm 8, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0048] Working principle: In this embodiment, when the fire equipment status monitoring sensor is in use, the housing 3 is first fixed to the fire pipeline 1, the filter plate 31 is slidably attached to the housing 3, the door 32 is closed, and the multi-channel regulated power supply 35 is turned on, after which the exhaust fan 34 starts to rotate and start to draw air into the housing 3. After the device starts to run, the water pressure sensor 4 monitors the water pressure in the fire pipeline 1, the displacement sensor 5 monitors the opening and closing status of the fire cabinet 2 door, and the smoke sensor 6 monitors harmful substances in the air. The dust in the air that affects the accuracy of the sensors is isolated outside the housing 3 by the filter plate 31 and the filter screen 33. When each sensor detects an abnormal situation, it will transmit an abnormal signal to the microcontroller 7, and then the microcontroller 7 will control the audible and visual alarm 8 to sound an alarm.

[0049] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
