Description

Technical Field

[0001] This utility model specifically relates to a mine ventilation monitoring device, belonging to the technical field of ventilation monitoring systems. Background Technology

[0002] Underground mines typically have uneven roads and limited space, making it inconvenient to carry ventilation monitoring devices, which are usually quite heavy and cumbersome. While mines usually have cableways that can be used to move ventilation monitoring systems, existing systems offer limited options for carrying them, making them inconvenient to use. Therefore, to address this issue, a portable and easy-to-use ventilation monitoring system can be designed.

[0003] Chinese patent publication (patent number: CN209523773U) discloses a mine ventilation monitoring system, including a monitoring unit and a portable mechanism. The bottom of the inner surface of the outer sleeve is connected to the bottom of the outer surface of the inner block, the top of the outer surface of the inner block is connected to the bottom of the outer surface of the telescopic rod, the left side of the bottom of the outer surface of the monitoring unit is connected to the top of the outer surface of the roof plate, the bottom of the outer surface of the roof plate is connected to the top of the outer surface of the universal wheel mounting body, the bottom of the outer surface of the universal wheel mounting body is movably connected to the outer surface of the movable wheel, and the middle left side of the outer surface of the monitoring unit is connected to the right side of the outer surface of the buffer plate. This invention, through the use of external threaded columns and internal threaded cylinders, allows for easier movement on mine cableways. The use of the inner block and outer sleeve also makes the device convenient to carry and use. However, this invention focuses excessively on mechanical carrying methods, neglecting the core functions and professional performance required for ventilation monitoring equipment to adapt to the mine environment. The design lacks an integrated wireless transmission module, requiring monitoring data to be manually read on-site or exported via wired connection, thus failing to achieve real-time alarm for abnormal ventilation conditions. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a mine ventilation monitoring device to achieve real-time monitoring and timely alarm.

[0005] A mine ventilation monitoring device includes a main component;

[0006] The main component includes a base plate, a rotating rod rotatably connected to the top of the base plate via a rotating shaft, an impeller frame mounted on the top of the rotating rod rotatably, four fan blades mounted on the outer side wall of the impeller frame, a gear rotatably mounted on the outer side wall of the rotating rod rotatably, a base mounted on the top of the base plate, a rotating rod rotatably connected to the top of the base via a rotating shaft, a gear rotatably fixedly connected to the top of the rotating rod rotatably, the gear rotatably and the gear rotatably meshing, eight connecting rods mounted on the outer side wall of the rotating rod rotatably, a contact point rotatably mounted at the end of each connecting rod away from the rotating rod rotatably, a counter mounted on the top of the base plate, and a contact point rotatably mounted on one side of the counter.

[0007] Furthermore, the counter is equipped with a counting display screen, and a zeroing button is installed on one side of the counter.

[0008] Furthermore, an audible alarm is installed on the top of the base plate, and the audible alarm is signal-connected to the counter.

[0009] Furthermore, a light alarm is installed on the top of the base plate, and the light alarm is connected to the counter signal.

[0010] Furthermore, a battery box is installed on the top of the base plate, and a battery is installed inside the battery box. The battery is electrically connected to the counter, the sound alarm, and the light alarm.

[0011] Furthermore, four grounding plugs are installed at the bottom of the base plate.

[0012] Furthermore, the size of gear one is larger than the size of gear two.

[0013] Furthermore, the fan blade has a concave shape on one side and a convex shape on the other.

[0014] Beneficial effects:

[0015] I. This utility model, through the setting of gear one and gear two, and the special fan blade design in the main component of the device, effectively captures the dynamic airflow, drives the impeller frame and rotating rod one to rotate, and through the meshing transmission of gear one and the smaller gear two, the low-speed rotation of the fan blade is amplified and converted into the high-frequency rotational motion of rotating rod two and its connecting rod. The contact point one fixed at the end of the connecting rod rotates at high speed with the rod and periodically contacts the contact point two on the counter, accurately converting the continuous change of physical airflow into a quantifiable electrical pulse signal input to the counter, so that the device can accurately grasp the changes in ventilation in the mine.

[0016] II. This utility model, through the setting of a counter and a counting display screen, continuously accumulates the number of pulses, which is intuitively reflected on the counting display screen. The operator can easily reset it through the zeroing button. When the accumulated number of pulses is lower than the preset safety threshold, the counter immediately triggers the sound alarm and light alarm connected to its signal, and simultaneously emits a high-decibel sound alarm and a conspicuous eye signal in the complex underground environment, forming a local alarm with dual sound and light and strong perception, ensuring that nearby workers can detect ventilation abnormalities at the first time regardless of their visual or auditory conditions, thus increasing the practicality of the device.

Eight connecting rods 109 are mounted on the outer side wall of the rotating rod 107. A contact 110 is mounted on the end of the connecting rod 109 away from the rotating rod 107. A counter 116 is mounted on the top of the base plate 101. A contact 111 is mounted on one side of the counter 116.

[0025] As a technical optimization of this utility model, the counter 116 is provided with a counting display screen 112, and a zeroing button 113 is installed on one side of the counter 116.

[0026] As a technical optimization of this utility model, a sound alarm 119 is installed on the top of the base plate 101, and the sound alarm 119 is connected to the counter 116.

[0027] As a technical optimization of this utility model, a light alarm 120 is installed on the top of the base plate 101, and the light alarm 120 is connected to the counter 116 by signal.

[0028] As a technical optimization of this utility model, a battery box 121 is installed on the top of the base plate 101. A battery is installed inside the battery box 121, and the battery is electrically connected to the counter 116, the sound alarm 119 and the light alarm 120.

[0029] As a technical optimization of this utility model, four ground plugs 122 are installed at the bottom of the base plate 101.

[0030] As a technical optimization of this utility model, the size of gear one 105 is larger than the size of gear two 106.

[0031] As a technical optimization of this utility model, the fan blade 103 has a concave shape on one side and a convex shape on the other side.

[0032] Working principle: The device is installed in the mine ventilation duct, and is firmly fixed in place by inserting four ground plugs 122 into the ground at the bottom of the base plate 101, adapting to uneven environments. When there is airflow in the ventilation duct, the fan blades 103, with special aerodynamic design, can efficiently capture the power generated by the air pressure difference, driving the impeller frame 102 to rotate around the axis of the rotating rod 104. The rotation of the impeller frame 102 directly drives the rotating rod 104, which is rigidly connected to it, to rotate synchronously. A large gear 105 is fixedly installed on the outer wall of the rotating rod 104. The gear 105 meshes tightly with a smaller gear 106 installed on the top of the rotating rod 107. Because the size of the gear 105 is significantly larger than that of the gear 106, the gear 105 meshes tightly with the smaller gear 106 installed on the top of the rotating rod 107. Wheel 106, based on the gear transmission principle, constitutes a speed-increasing transmission mechanism. When the high-speed rotating connecting rod 109 drives its end contact 110 to pass over and contact contact 111, which is fixedly installed on one side of the counter 116 on the top of the base plate 101, the two contacts make instantaneous physical contact and conduction. Each contact generates a brief electrical pulse signal in the circuit formed by the counter 116 and contact 111. The counter 116 continuously receives these electrical pulse signals. The internal circuit of the counter 116 accurately counts the input pulses and displays the total number of accumulated pulses in real time on its equipped counting display screen 112. The counting display screen 112 displays the unit time in real time. The number of pulses counted within a given timeframe provides on-site personnel with a direct reference value for airflow activity. When the mine's excavation depth increases, leading to insufficient ventilation, the ventilation belts or ducts are extended, requiring the device to be moved to a new location. The operator first presses the reset button 113 on counter 116 to reset the accumulated pulse count to zero, marking the start of a new monitoring cycle at the new location. The device then continues to operate at the new location, with counter 116 accumulating the pulse count within the new cycle. Based on the new cycle's airflow data displayed on counter display 112, personnel determine whether the area's safety requirements are met. The reset operation ensures the independence and accuracy of data from each monitoring location. The extension cycle for the fan or ventilation belt is approximately one month. Once, the counter 116 has a preset pulse count threshold representing the lower limit of safe ventilation. When the actual airflow weakens, the fan blade 103 speed decreases, which in turn causes the rotating rod 107 speed to decrease, the contact frequency of the contact point to decrease, and the number of pulses generated per unit time to decrease. Finally, when the total number of pulses accumulated by the counter 116 in a specific time period is lower than the preset safety threshold, the counter 116 immediately triggers a local alarm. The sound alarm 119 emits a loud and penetrating alarm sound, which can be clearly heard even in areas with high background noise in the well. The light alarm 120 emits a bright and flashing warning light, providing a conspicuous visual warning in dimly lit or dusty environments.
