Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically a fire protection and safety device for mud tank areas. Background Technology

[0002] Drilling mud tank area is a critical area in oil drilling operations, mainly used for storing and circulating drilling fluid (mud). Because the mud contains hydrocarbons (such as oil-based mud), high-temperature and high-pressure equipment (such as mud pumps), and electrical facilities, this area is prone to fire hazards such as static electricity explosion of flammable gases, spontaneous combustion at high temperatures, or fire caused by equipment short circuits.

[0003] Currently, the common methods for extinguishing fires in mud areas are traditional water spraying or handheld fire extinguishers. Water spraying has the drawback that it may contaminate the mud, such as diluting it. Handheld fire extinguishers have the drawback that they rely on manual operation, have a slow response time, require personnel to be close to the fire source, and pose a high safety risk. In addition, because they rely on manual operation, fires at night or in uninhabited areas cannot be detected and controlled in a timely manner.

[0004] Based on the above analysis, this solution designs a fire safety device that integrates multiple sensors for fire detection and can automatically spray extinguishing agents. Utility Model Content

[0005] The purpose of this utility model is to provide a fire protection and security device for mud tank areas. This device adopts multi-sensor fusion fire detection technology and can automatically carry out fire extinguishing operations without relying on manual operation. It is especially suitable for nighttime or uninhabited areas, and solves the shortcomings of existing fire extinguishing methods in mud tank areas.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fire protection and safety device for a mud tank area includes a cabinet. The cabinet is equipped with at least an extinguishing agent storage compartment, an extinguishing agent spraying drive mechanism, an alarm linkage mechanism, a fire detection mechanism, and a main control mechanism. The extinguishing agent storage compartment is used to store the required extinguishing agent. The extinguishing agent spraying drive mechanism is used to automatically spray the extinguishing agent into a designated area. The alarm linkage mechanism is used to issue a fire alarm. The fire detection mechanism is used to monitor the fire situation in the monitored area in real time and trigger it when a fire occurs.

The solenoid valve is controlled to open and close by the main control mechanism, thereby controlling the on / off of the corresponding high-pressure pipeline. The nozzle is located at the end of the high-pressure pipeline and extends to the outside of the cabinet.

[0009] As a preferred embodiment of this application: the nozzle is located at the bottom of the cabinet after installation, and the axis of the nozzle is at an elevation angle of 25-30° to the horizontal plane.

[0010] As a preferred embodiment of this application: the fire detection mechanism includes at least two of a smoke sensor, a temperature sensor, and a pyroelectric infrared sensor. The smoke sensor, temperature sensor, and pyroelectric infrared sensor communicate with the main control mechanism through a serial communication interface, and their probes extend to the outside of the cabinet.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0027] This embodiment provides a fire protection and safety device for mud tank areas, such as... Figure 1-2As shown, the equipment includes a cabinet 10, preferably made of 304 stainless steel. Ventilation holes 24 covered with HEPA filters are provided on the side of the cabinet 10 for ventilation, heat dissipation, dustproofing, and explosion-proofing. In this embodiment, the cabinet 10 includes a cabinet body and a door, with the door locked to the cabinet body using a conventional latch 25. The cabinet 10 is equipped with at least a fire extinguishing agent storage compartment 11, a fire extinguishing agent spraying drive mechanism, an alarm linkage mechanism, a fire detection mechanism, a lighting mechanism, and a main control mechanism 19. The fire extinguishing agent storage compartment 11 is the internal cavity of the cabinet 10, used to store the required fire extinguishing agent. It is understood that the specific material of the fire extinguishing agent can be selected according to the usage environment and safety requirements, such as at least one of foam fire extinguishing agent, carbon dioxide fire extinguishing agent, or dry powder fire extinguishing agent. In this embodiment, to simplify the design structure and to achieve high-pressure spraying, it is preferable to install at least one set of conventional filling fire extinguishers 111 inside the fire extinguishing agent storage compartment 11. These fire extinguishers 111 are not only convenient... The filling of the extinguishing agent enables sustainable use, and its high-pressure injection principle eliminates the need for additional high-pressure pumps and other components, simplifying the design process and reducing costs. The extinguishing agent injection drive mechanism automatically sprays the extinguishing agent into a designated area without human intervention, achieving unattended automated fire extinguishing. The alarm linkage mechanism is used for fire alarms; in this embodiment, the alarm linkage mechanism issues local and remote alarms upon detecting a fire. The fire detection mechanism monitors the monitored area in real time and is triggered when a fire occurs. It is understood that the fire detection mechanism should have the function of simultaneously detecting open flames and smoldering fires to achieve early fire prediction. The main control mechanism 19 is electrically connected to the extinguishing agent injection drive mechanism, the alarm linkage mechanism, and the fire detection mechanism to coordinate the actions of each mechanism. In this embodiment, the control mechanism, the extinguishing agent injection drive mechanism, the alarm linkage mechanism, and the fire detection mechanism are preferably all located inside the cabinet door for easy maintenance. Of course, if necessary, they can also be located inside the cabinet cavity.

[0028] As a preferred embodiment, the extinguishing agent spraying drive mechanism includes at least one high-pressure pipeline 12, which is connected to the extinguishing agent storage chamber 11. A solenoid valve 13 and a nozzle 14 are provided on the high-pressure pipeline 12. The solenoid valve 13 is controlled by the main control mechanism 19 to open and close, thereby controlling the on / off state of the corresponding high-pressure pipeline 12. In this embodiment, the solenoid valve 13 is preferably a 12V normally closed solenoid valve 13 (model: 2W-160-15). The nozzle 14 is located at the end of the high-pressure pipeline 12 and extends to the outside of the cabinet 10. The nozzle 14 adopts the existing fan-shaped spray area, with a preferred spray angle of 40°-60°. This allows for targeted and directional fire extinguishing, improving the effective utilization of the extinguishing agent.

[0029] In this embodiment, the high-pressure pipeline 12 preferably includes two lines, and the two high-pressure pipelines 12 are respectively connected to the conventional fire extinguisher 111 installed in the fire extinguishing agent storage chamber 11. Of course, when the space in the fire extinguishing agent storage chamber 11 is limited, the two high-pressure pipelines 12 can also be connected to the same conventional fire extinguisher 111. In use, when there is a fire extinguishing requirement, the main control mechanism 19 can control the solenoid valve 13 on either high-pressure pipeline 12 to open the pipeline and spray the fire extinguishing agent to the designated location through the nozzle 14. In this embodiment, the high-pressure pipeline 12 can be made of corrosion-resistant flexible hose, which is beneficial for the pipeline to be laid in the cabinet 10.

[0030] It should be noted that when in use, the device can be installed above the monitored environment by means of suspension or erection through the fixing component 23. For example, it can be installed above the factory building or rain shelter in the mud tank area or other sites that need fire monitoring, and monitor from above. Therefore, it is understandable that the nozzle 14 of the fire extinguishing agent spraying drive mechanism and the probe of the fire detection mechanism should be set near the bottom of the cabinet 10 after it is installed. In this embodiment, the bottom is preferably the cabinet door side of the cabinet 10.

[0031] As a preferred embodiment, the nozzle 14 is located at the bottom of the cabinet 10 after installation, i.e., on the cabinet door. The axis of the nozzle 14 is at an elevation angle of 25-30° to the horizontal plane. This can expand the horizontal coverage of a single nozzle 14 and reduce the number of nozzles 14. On the other hand, it can enhance the dispersion and trajectory optimization of the extinguishing agent, increase the contact area with the flame, and significantly improve the extinguishing efficiency, especially suitable for environments with large spaces.

[0032] As a preferred embodiment, the fire detection mechanism includes at least two of the following: a smoke sensor 20, a temperature sensor 21, and a pyroelectric infrared sensor 22. The smoke sensor 20, temperature sensor 21, and pyroelectric infrared sensor 22 communicate with the main control mechanism 19 via a serial communication interface, and their probes extend to the outside of the cabinet 10. In this embodiment, the fire detection mechanism is preferably installed on the cabinet door of the cabinet 10, and the probes of each sensor also extend to the outside of the cabinet door.

[0033] Specifically, the smoke sensor 20 has a fast response speed to smoldering fires and can quickly determine the fire situation by detecting tiny smoke particles, thus enabling early fire prediction. In this embodiment, the smoke sensor 20 is preferably an MQ-2 photoelectric sensor. The temperature sensor 21 mainly detects the environment after it has heated up and determines the fire situation by sensing temperature changes, which can also determine the open flame stage. In this embodiment, the temperature sensor 21 is preferably a DS18B20 digital sensor. The pyroelectric infrared sensor 22 is sensitive to dynamic infrared radiation, which includes flickering flames and moving human bodies. The pyroelectric infrared sensor 22 can be used to locate the flame position and predict the fire spread range. In this embodiment, the pyroelectric infrared sensor 22 is preferably an MLX90614 infrared temperature sensor.

[0034] In practical use, the complementary performance of each sensor can be utilized for multi-sensor fusion. The combination of smoke sensor 20 and temperature sensor 21 is used to reduce the false alarm rate, and the combination of pyroelectric infrared sensor 22 and temperature sensor 21 is used to accurately locate the flame position. In this embodiment, the number of each sensor can be selected according to actual needs. In this embodiment, it is preferred that at least multiple pyroelectric infrared sensors 22 are included, which are respectively set in different positions of the cabinet 10. The specific position of the flame is determined by multi-sensor differential positioning, and then the solenoid valve 13 on the high-pressure water supply pipeline 12 is controlled by the main control mechanism 19 to activate the nozzle 14 in that position for targeted fire extinguishing.

[0035] As a preferred embodiment, the alarm linkage mechanism includes an audible and visual alarm 15 and a remote alarm module 16. The audible and visual alarm 15 is connected to the GPIO pin of the main control mechanism 19. The audible and visual alarm 15 includes a buzzer and LED beads, which are respectively connected to the GPIO pin of the main control mechanism 19 and are triggered by high and low levels. The remote alarm module 16 is connected to the main control mechanism 19 through a serial communication interface. The remote alarm module 16 is an ESP-01S WiFi module. The fire information is remotely uploaded to the host computer through the remote alarm module 16 so that the staff can be informed in time. This embodiment uses the audible and visual alarm 15 and the remote alarm module 16 to realize both local alarm and remote alarm, which improves the reliability of the equipment.

[0036] As a preferred embodiment, the cabinet 10 is also provided with a lighting mechanism for use as a light source during normal or critical times. The lighting mechanism includes an LED array 17 and a MOSFET driving module 18. The LED array 17 is composed of multiple 2835 surface-mount LEDs connected in parallel. This structure of LEDs is energy-saving and lightweight. The gate of the MOSFET driving module 18 is connected to the GPIO pin of the main control mechanism 19. The MOSFET driving module 18 acts as a switch to control the on / off state of the LED array 17.

[0037] As a preferred embodiment, the cabinet 10 is also equipped with a power supply unit 27, which consists of a 12V rechargeable battery and an AC / DC conversion module. The input of the AC / DC conversion module is connected to an external 220V AC mains power supply, and the output is divided into two paths: one path is connected to the rechargeable battery for charging, and the other path is connected to other mechanisms within the cabinet 10 to directly supply power to each mechanism. In this embodiment, under normal conditions, the rechargeable battery supplies power to the equipment system. When the rechargeable battery has a low charge, the power is switched to the AC / DC conversion module for direct power supply. That is, in this embodiment, the rechargeable battery and the AC / DC conversion module form a main and backup power supply to provide power for the normal operation of the equipment system. It can be understood that since the system is in a low-power state, in order to simplify the design structure, only the rechargeable battery can be used to supply power to the equipment system, and the AC / DC conversion module can only be used as the charging terminal for the rechargeable battery.

[0038] like Figure 3 The diagram shown is a control principle diagram of the fire protection and security equipment provided in this embodiment. The main control mechanism 19 adopts a main control chip of model STM32F103C8T6.

[0039] In normal use, the main control chip can turn on the LED array 17 via the MOSFET driver module 18 for use as a regular lighting lamp. The temperature sensor 21, smoke sensor 20, and pyroelectric infrared sensor 22 in the fire detection sensors detect the fire situation in the external environment in real time. When the preset conditions of the temperature sensor 21 and smoke sensor 20 are triggered simultaneously, it indicates that a fire has occurred. This stage can be the smoldering stage or the initial stage of open flame. The main control chip controls the opening of the solenoid valve 13 on at least one of the two high-pressure pipelines 12 via the relay 26 to automatically spray the extinguishing agent. At the same time, the alarm is triggered by the audible and visual alarm 15 and the remote alarm module 16. Meanwhile, the infrared radiation signals collected by multiple sets of pyroelectric infrared sensors 22 are used to determine the specific location of the flame or fire. This is achieved by comparing the data collected by multiple sets of pyroelectric infrared sensors 22. Once the accurate location is determined, only the solenoid valve 13 of the high-pressure pipeline 12 corresponding to that location is opened for precise spraying. This achieves precise fire extinguishing on the one hand and improves the utilization rate of the extinguishing agent on the other.

[0040] In summary, the fire protection and safety equipment for mud tank areas proposed in this solution has advantages such as compact structure, flexible and reliable use, and automatic fire extinguishing. It is suitable for mud tank areas located in remote areas, especially for nighttime or unattended areas. It is understood that mud tank areas are the preferred site for this embodiment, but it can also be applied to other fields or sites when necessary, such as as a household fire extinguishing product.
