Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically a fire alarm control device. Background Technology

[0002] In traditional port fire protection systems, alarm devices are mostly installed separately and in isolation, resulting in common problems such as delayed alarm response, lack of linkage support, and inability to accurately locate fires. This is especially true in areas with core mechanical equipment such as quay cranes, where the confined space and complex structure make firefighting extremely difficult and risky. Therefore, ports need a more intelligent, interconnected, and adaptable fire alarm system.

[0003] The shortcomings of traditional systems lie in the inefficient integration of alarm signals with the platform, inaccurate positioning, high false alarm rates, and inability to effectively link with on-site fire suppression systems, significantly limiting fire emergency response efficiency. Furthermore, existing systems often cannot be integrated with the existing industrial ring network systems in port control centers and lack customized adaptations for quay crane PLC equipment, hindering the improvement of the overall system automation level. Therefore, developing a new type of fire alarm system with high integration, fast response speed, suitability for port scenarios, and support for remote control and real-time linkage has become crucial for enhancing port fire protection capabilities. Summary of the Invention

[0004] The purpose of this utility model is to address the above-mentioned problems. This utility model provides a fire alarm control device, which has the advantages of recognizing the external environment and quickly adjusting the fire water source.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The present invention discloses a fire alarm control device, including a support component, a working component connected inside the support component, a water pipe connected to the working component, and the water pipe passing through the support component, and a detector being provided inside the support component.

[0006] Preferably, the carrier component includes a housing, and a cavity is formed inside the housing, wherein the working component and the detector are both located inside the cavity.

[0007] Preferably, a control box is connected to the housing, and an electronic connector is provided on one side of the control box, and the electronic connector is fixedly connected to the housing.

[0008] Preferably, both the working component and the detector are connected to a connecting component, and the end of the connecting component away from the working component and the detector is electrically connected to the electronic connector.

[0009] Preferably, the working component includes a power unit, one end of which is connected to a piston, a stop is provided on the side of the piston away from the power unit, and the water pipe communicates with the space between the piston and the stop.

[0010] Preferably, the connection assembly includes a communication cable and a connecting line, wherein one end of the communication cable is connected to the detector and the end away from the detector is connected to the electronic connector, one end of the connecting line is connected to the working component and the end away from the working component is connected to the electronic connector.

[0011] Preferably, an identification part is connected to the end of the connecting component away from the electronic connector, and the control box and the electronic connector are connected through the connecting component.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The detector collects environmental parameters and transmits them to the identification unit via the communication cable of the connecting component. The identification unit analyzes the data, eliminates false alarms, self-calibrates, and assesses the risk. The data is then fed back to the control box and the working component via electronic connectors and connecting lines. The control box, based on the risk level, controls the power unit of the working component to drive the piston, adjusting the water pipe diameter. Low-risk situations involve a small amount of water flow, medium-risk situations involve increased flow and early warning, and high-risk situations involve full-load water supply. It also links with the quay crane PLC equipment, solving problems such as response delay and poor linkage in traditional systems, and improving the efficiency and automation level of port fire emergency response.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-3 As shown, this utility model discloses a fire alarm control device, including a support component 1 for connecting and supporting the device. A working component 7 for water flow is connected inside the support component 1. A water pipe 3 is connected to the working component 7. The working component 7 can regulate the water flow status of the water pipe 3, and the water pipe 3 passes through the support component 1. A detector 8 for identifying the environmental status inside the support component 1 is provided inside the support component 1 to ensure that the environment inside the support component 1 can meet the normal use of the alarm control device.

[0017] It should be noted that the detector 8 can identify the temperature, humidity and dust concentration inside the cavity 102. The detector 8 has a built-in temperature sensor, smoke sensor, humidity sensor and dust concentration sensor, which can collect environmental parameters of the cavity 102 and the surrounding area in real time.

[0018] Furthermore, the supporting component 1 includes a housing 101 for connection and fixation. The housing 101 has a cavity 102 for component connection. The working component 7 and the detector 8 are both located in the cavity 102. The housing 101 protects the working component 7 and the detector 8.

[0019] Furthermore, a control box 2 for electrically regulating the device is connected to the housing 101. An electronic connector 4 is provided on one side of the control box 2 and is fixedly connected to the housing 101. The electronic connector 4 collects and distributes the electrical signals generated by the device to ensure that the control box 2 can control and regulate the device in a timely manner according to the status of the device, thereby reducing the data pressure on the control box 2.

[0020] Furthermore, in order to improve the efficiency of information transmission within the control device, both the working component 7 and the detector 8 are connected to a connection component 6 for data transmission. The end of the connection component 6 away from the working component 7 and the detector 8 is electrically connected to the electronic connector 4, thereby controlling the working state of the working component 7 through the connection component 6.

[0021] Furthermore, the working component 7 includes a power unit 701 for driving the piston 702. One end of the power unit 701 is connected to the piston 702 for opening and closing the water pipe 3. A stop block 703 is provided on the side of the piston 702 away from the power unit 701, which abuts against the piston 702. The space between the water pipe 3, the piston 702, and the stop block 703 is connected. When the piston 702 and the stop block 703 are separated, the water flow in the water pipe 3 is allowed to pass through. When the piston 702 and the stop block 703 abut against each other, the water flow in the water pipe 3 is isolated.

[0022] Furthermore, the connection component 6 includes a communication cable 601 and a connection line 602, wherein one end of the communication cable 601 is connected to the detector 8 and the end away from the detector 8 is connected to the electronic connector 4, one end of the connection line 602 is connected to the working component 7 and the end away from the working component 7 is connected to the electronic connector 4, ensuring that the communication cable 601 and the connection line 602 perform data splitting on the electronic connector 4.

[0023] Furthermore, the end of the connecting component 6 away from the electronic connector 4 is connected to an identification unit 5 for analyzing the data of the detector 8, and the control box 2 and the electronic connector 4 are connected via the connecting component 6.

[0024] The identification unit 5 integrates a microprocessor and a preset algorithm, which can perform fusion analysis on multi-sensor data. That is, by judging the correlation between the rate of temperature change and the smoke concentration, it can eliminate false alarms caused by dust accumulation and environmental humidity fluctuations. When the detection parameters exceed the preset threshold, the identification unit 5 generates a fire risk signal and transmits it to the electronic connector 4 through the communication cable 601.

[0025] To improve detection accuracy, the identification unit 5 can periodically compare the historical detection data of the detector 8 with the environmental database of the port control center. If the deviation of a sensor data exceeds ±5%, the self-calibration program is automatically triggered. At the same time, when the detector 8 malfunctions, the identification unit 5 immediately generates a fault signal and alerts the maintenance personnel through the display module of the control box 2 to avoid safety hazards caused by detection failure.

[0026] In addition, considering the differences in fire risk levels in different areas of the port, control box 2 has a built-in hierarchical control algorithm: When the identification unit 5 transmits a low-risk signal, the control box 2 controls the power unit 701 to drive the piston 702 to open only 1 / 3 of the diameter of the water pipe 3 through the electronic connector 4 and the connecting line 602, so as to achieve a small amount of water flow for cooling and avoid water waste. When a risk signal is transmitted, piston 702 opens to 2 / 3 of its diameter, and at the same time, control box 2 sends an early warning message to the port fire duty room through the industrial ring network to remind personnel to conduct on-site verification.

[0027] When a high-risk signal is transmitted, piston 702 is fully opened, water pipe 3 is supplied with water at full load, and at the same time, the quay crane PLC equipment is activated to suspend the operation of the quay crane and start the emergency lighting and evacuation indication system.

[0028] During real-time monitoring, the temperature sensor, smoke sensor, humidity sensor and dust concentration sensor built into the detector 8 continuously collect environmental parameters of the cavity 102 and the surrounding area, and transmit the raw data to the identification part 5 at the end of the connection component 6 away from the electronic connector 4 via the communication cable 601.

[0029] The microprocessor integrated in the identification unit 5 performs fusion analysis on multi-dimensional data based on a preset algorithm. On the one hand, it judges the correlation between temperature change rate and smoke concentration to eliminate false alarms caused by port dust accumulation and diurnal humidity fluctuations. On the other hand, it periodically compares the historical detection data of detector 8 with the environmental database of the port control center. If the deviation of a sensor data exceeds ±5%, a self-calibration program is automatically triggered to ensure detection accuracy. If a fault is detected in detector 8, the identification unit 5 immediately generates a device fault signal and feeds it back to the control box 2 through communication cable 601, electronic connector 4 and connection component 6. The display module of the control box 2 simultaneously reminds the operation and maintenance personnel to avoid safety hazards caused by detection failure.

[0030] When the identification unit 5 determines that the environmental parameters exceed the preset threshold, it generates a corresponding control signal according to the risk level: if it is a low-risk signal (such as a slight local temperature rise but no smoke), the signal is transmitted to the electronic connector 4 via the communication cable 601, and then the electronic connector 4 sends a drive command to the power unit 701 of the working component 7 via the connecting line 602. The power unit 701 drives the piston 702 to move only away from the stop block 703 to 1 / 3 of the diameter of the water pipe 3, so as to achieve a small amount of water cooling, thereby reducing water consumption while controlling the fire hazard.

[0031] If the signal is of medium risk (e.g., a small amount of smoke and a continuous rise in temperature), the power unit 701 drives the piston 702 to move to 2 / 3 of the diameter of the water pipe 3, increasing the water flow. At the same time, the electronic connector 4 feeds back the risk signal to the control box 2 through the connection component 6. The control box 2 sends an early warning message to the fire duty room through the port industrial ring network, reminding personnel to go to the site for verification, further confirm the fire situation, and take manual intervention measures.

[0032] If a high-risk signal is detected (such as a sudden increase in smoke concentration and a temperature reaching the ignition threshold), the power unit 701 drives the piston 702 to completely disengage from the stop block 703, and the water pipe 3 supplies water at full load to quickly suppress the fire. At the same time, the control box 2 links the quay crane PLC equipment through the industrial ring network to suspend the operation of the quay crane and activate the emergency lighting and evacuation guidance system in the surrounding area. This effectively solves the problems of delayed alarm response and poor linkage in traditional port fire protection systems, and significantly improves the efficiency of fire emergency response.
