Description

Technical Field

[0001] This invention relates to the field of underground coal mine operation equipment technology, and in particular to a multifunctional smart mine lamp device for coal mine operations. Background Technology

[0002] The underground working environment in coal mines is extremely complex. Not only are there explosive gases such as methane, but the coal dust concentration often reaches 30-2000 g / m³, and the temperature and humidity fluctuate widely from -20℃ to 60℃. At the same time, there is also strong electromagnetic interference.

[0003] With the advancement of smart mine construction, traditional mine lamps with only lighting functions can no longer meet the needs of underground safety management. The industry is gradually developing multi-functional smart mine lamps that integrate lighting, communication, and environmental monitoring. These mine lamps need to integrate multiple heat-generating components such as LED lamp panels, communication modules, oxygen, methane, and dust sensor modules. The total heat generation power is 2-3 times higher than that of traditional mine lamps, and the heat dissipation load is increased dramatically. Among them, the LED lamp panel, as the core lighting component, can easily exceed 120°C in local temperature during operation. If the heat cannot be dissipated in time, it will not only accelerate the light decay of LEDs, but may also trigger the risk of explosive gas ignition.

[0004] Therefore, a completely new heat dissipation design is needed to solve the above-mentioned technical defects and meet the safe and stable operation requirements of multi-functional smart mining lamps used in coal mine operations. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This multi-functional smart mine lamp device for coal mining operations uses a cooling mechanism that directly attaches a water-cooled plate to the LED lamp panel and uses a micro water pump to drive the circulation of coolant.

Therefore, they should not be construed as limiting this invention.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0036] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0037] Please see Figure 1-6 The present invention provides a technical solution: a multi-functional smart mine lamp device for coal mine operations, including a shell 1, the shell 1 being a hollow cuboid structure, an LED lamp plate 2 embedded at the bottom end of the shell 1, a temperature sensor 3 fixedly connected to the LED lamp plate 2, and a lamp cover 4 fixedly connected to the bottom end of the shell 1 corresponding to the outer side of the LED lamp plate 2.

[0038] A cooling mechanism is provided on the LED light panel 2 inside the housing 1, a communication mechanism is provided inside the housing 1, and an environmental monitoring mechanism is provided on the housing 1.

[0039] When the device is running, the LED light panel 2 is powered on and emits light to provide illumination for underground coal mine operations. The lamp cover 4 protects the LED light panel 2 from dust and water droplets directly contacting the light panel and affecting its service life. The LED light panel 2 generates heat during operation. The temperature sensor 3 is a TS200 series explosion-proof temperature sensor that can monitor the temperature of the LED light panel 2 in real time. When the temperature exceeds the default preset threshold of 70°C, the temperature sensor 3 transmits a signal to the internal control unit of the device, triggering the cooling mechanism to start. In addition, the preset threshold can be remotely configured through the ground platform.

[0040] Meanwhile, the shell 1 is made of flame-retardant ABS or aluminum alloy with an IP65 protection rating to prevent dust from entering. The internal communication mechanism can transmit information such as the location of the operator and the status of the equipment in real time. The environmental monitoring mechanism on the shell 1 continuously collects downhole environmental parameters. The three work together to ensure the stable and safe operation of the device in the complex downhole environment, providing the operator with dual protection of lighting and safety monitoring.

[0041] Furthermore, the cooling mechanism includes a water-cooled plate 6, which is fixedly connected to the LED light panel 2 inside the housing 1, and a water-cooling head 7 is fixedly connected to the water-cooled plate 6.

[0042] A coolant reservoir 8 is fixedly connected to the rear side of the interior of the housing 1. The coolant reservoir 8 has a hollow structure and an exhaust port 9 is fixedly connected to the top of the coolant reservoir 8.

[0043] A one-way exhaust valve 10 is fixedly connected to the exhaust port 9;

[0044] The coolant storage tank 8 has an outlet 11 and an inlet 12 fixedly connected to its left side. Inside the housing 1 is a drive motor 14, and the bottom of the drive motor 14 is fixedly connected to a fixed bracket 15.

[0045] The fixed bracket 15 is fixedly connected to the bottom inside the housing 1;

[0046] A micro water pump 13 is fixedly connected to the output end of the fixed bracket 15, a rubber tube 16 is fixedly connected to the input end of the micro water pump 13, and the other end of the rubber tube 16 is fixedly connected to the water outlet 11.

[0047] A rubber tube 16 is fixedly connected to the output end of the micro water pump 13, and the other end of the rubber tube 16 is fixedly connected to the input end of the water cooling head 7. The rubber tube 16 is fixedly connected to the output end of the water cooling head 7.

[0048] The other end of the rubber tube 16 is fixedly connected to the water inlet 12;

[0049] When the temperature sensor 3 detects that the temperature of the LED light panel 2 exceeds the standard, the control unit starts the drive motor 14. The drive motor 14 is a DC micro motor of model ZYTD-38SRZ-EX, which drives the micro water pump 13 of model DC30-01-EX to run. The micro water pump 13 draws coolant from the outlet 11 of the coolant storage tank 8 through the rubber tube 16 at the input end.

[0050] Coolant is delivered to water block 7. The coolant is deionized water with food-grade preservatives. Water block 7 is tightly fitted to water plate 6. When the coolant flows in water block 7, it absorbs heat from water plate 6. After absorbing heat, the coolant flows back to the inlet 12 of coolant reservoir 8 through rubber tube 16 at the output end of water block 7, forming a circulation for heat dissipation. During the coolant circulation, if gas is generated in the reservoir, one-way exhaust valve 10 (model PV01-EX) will automatically open to discharge the gas, avoiding gas resistance from affecting heat dissipation efficiency. Fixed bracket 15 ensures that drive motor 14 and micro water pump 13 remain stable during operation and do not shift. All pipelines use flame-retardant silicone tubing, and the joints use a double-clamp structure with a pressure resistance ≥0.3MPa and pass the sealing test.

[0051] Furthermore, the communication mechanism includes a communication module 17, which is fixedly connected to the front side of the bottom inside the housing 1, and two antennas 18 are fixedly connected to the communication module 17.

[0052] The other end of the antenna 18 extends out of the outer side of the housing 1;

[0053] During operation, the communication module 17 uses a LoRa module as its core component, with a communication distance of ≥300m. It receives and transmits signals through two antennas 18 protruding from the outer side of the housing 1, enabling data transmission in multiple scenarios. The antennas are intrinsically safe explosion-proof antennas with an IP65 protection rating. On one hand, the communication module 17 can receive dispatch instructions, safety warnings, and other information sent by the ground monitoring center, and transmit the information to the internal control unit of the device, and then provide feedback to the operators through relevant prompting components.

[0054] On the other hand, the communication module 17 can collect the operating status data of the device and send it to the ground monitoring center via the antenna 18 to ensure real-time communication between ground and underground workers, improve operational safety and collaborative efficiency. The design of the antenna 18 extending through the housing 1 can reduce the housing's obstruction of the signal and ensure communication distance and signal stability.

[0055] Furthermore, the environmental monitoring device includes an oxygen concentration sensor module 19 and a methane sensor module 20, which are fixedly connected to the left outer wall of the housing 1.

[0056] A dust sensor module 21 is fixedly connected to the right side of the housing 1;

[0057] When the environmental monitoring agency is working, the oxygen concentration sensor module 19 of model O2-A1 is used to detect the oxygen concentration in the underground air in real time. When the oxygen concentration is lower than the hypoxia threshold, the sensor module will transmit the abnormal signal to the control unit. The methane sensor module 20 of model GJJ100A continuously monitors the methane concentration. If the methane concentration exceeds the safety warning threshold, it will immediately send a warning signal.

[0058] The GCG5000 type explosion-proof dust sensor module 21 collects the dust concentration underground. When the dust concentration exceeds the threshold, an alarm is triggered. These sensor modules transmit the collected environmental data to the control unit in real time. The control unit uploads the data to the ground monitoring center through the communication module 17 of the LoRa module. On the other hand, if the parameter exceeds the standard, it immediately activates the audible and visual alarm to remind the workers to take timely safety measures and ensure the safety of the underground working environment.

[0059] Furthermore, a light intensity sensor 5 is fixedly connected to the top of the housing 1;

[0060] The light intensity sensor 5, model GQL0.1, is installed at the top of the housing 1 and can collect the light intensity of different areas in the coal mine in real time. The signal is transmitted to the control unit, which automatically reduces the brightness of the LED light panel 2 to reduce energy consumption.

[0061] Furthermore, an emergency button 22 is fixedly connected to the front side of the housing 1;

[0062] The emergency button 22 is an intrinsically safe explosion-proof button with an Ex ib I Mb self-locking function. As an emergency triggering component of the device, the operator can quickly press the emergency button 22 when an emergency occurs underground. After the emergency button 22 is triggered, it immediately sends an emergency signal to the internal control unit of the device. The control unit then activates the device's strong light alarm mode.

[0063] Working principle: When the temperature sensor 3 detects that the temperature of the LED light board 2 exceeds the standard, the control unit starts the drive motor 14. The drive motor 14 is a DC micro motor of model ZYTD-38SRZ-EX, which drives the micro water pump 13 of model DC30-01-EX to run. The micro water pump 13 draws coolant from the outlet 11 of the coolant storage tank 8 through the rubber tube 16 at the input end.

[0064] Coolant is delivered to water block 7, which is in close contact with water plate 6. As the coolant flows inside water block 7, it absorbs heat from water plate 6. After absorbing heat, the coolant flows back to the inlet 12 of coolant reservoir 8 through rubber tube 16 at the output end of water block 7, forming a circulation for heat dissipation. During the coolant circulation, if gas is generated in the reservoir, the one-way exhaust valve 10, model PV01-EX, will automatically open to discharge the gas, preventing air resistance from affecting heat dissipation efficiency. The fixed bracket 15 ensures that the drive motor 14 and the micro water pump 13 remain stable during operation and do not shift.

[0065] When the communication mechanism is in operation, the communication module 17 adopts a LoRa module. As the core component, the communication module 17 receives and transmits signals through two antennas 18 that protrude from the outside of the housing 1, realizing data transmission in multiple scenarios. On the one hand, the communication module 17 can receive dispatch instructions, safety warnings and other information sent by the ground monitoring center, and transmit the information to the internal control unit of the device, and then feed back to the operators through relevant prompting components.

[0066] On the other hand, the communication module 17 can collect the operating status data of the device and send it to the ground monitoring center via the antenna 18 to ensure real-time communication between ground and underground workers, improve operational safety and collaborative efficiency. The design of the antenna 18 extending through the housing 1 can reduce the housing's obstruction of the signal and ensure communication distance and signal stability.

[0067] When the environmental monitoring agency is working, the oxygen concentration sensor module 19 of model O2-A1 is used to detect the oxygen concentration in the underground air in real time. When the oxygen concentration is lower than the hypoxia threshold, the sensor module will transmit the abnormal signal to the control unit. The methane sensor module 20 of model GJJ100A continuously monitors the methane concentration. If the methane concentration exceeds the safety warning threshold, it will immediately send a warning signal.

[0068] The GCG5000 type explosion-proof dust sensor module 21 collects the dust concentration underground. When the dust concentration exceeds the threshold, an alarm is triggered. These sensor modules transmit the collected environmental data to the control unit in real time. The control unit uploads the data to the ground monitoring center through the communication module 17 of the LoRa module. On the other hand, if the parameter exceeds the standard, it immediately activates the audible and visual alarm to remind the workers to take timely safety measures and ensure the safety of the underground working environment.

[0069] Structural Description:

[0070] Water-cooled plate 6: Fixedly connected to the LED light board 2 inside the housing 1, it is the core component for heat conduction of the cooling mechanism; it is directly attached to the LED light board 2, allowing for maximum contact area with the light board, quickly absorbing the heat generated by the light board during operation, and preventing heat from accumulating locally on the light board; the metal material of the water-cooled plate 6 has high thermal conductivity, which can efficiently transfer heat to the coolant in the water-cooling head 7, laying the foundation for subsequent circulating heat dissipation, ensuring heat dissipation efficiency, and preventing the LED light board 2 from light decay or damage due to high temperature;

[0071] Water cooling head 7: Fixedly connected to the water cooling plate 6, it is the heat exchange component between the coolant and the water cooling plate 6 in the cooling mechanism; it fits tightly against the water cooling plate 6, allowing full contact with the surface of the water cooling plate 6, so that when the coolant flows in the water cooling head 7, it can absorb the heat conducted by the water cooling plate 6 to the maximum extent, thereby improving the heat exchange efficiency; at the same time, the flow channel design of the water cooling head 7 can guide the coolant to flow evenly, avoid local overheating, ensure stable cooling effect, and provide continuous cooling protection for the LED light panel 2;

[0072] Coolant reservoir 8: Fixedly connected to the rear side of the interior of housing 1, it has a hollow structure and is used to store the coolant required by the cooling mechanism. The hollow structure can hold a sufficient amount of coolant to meet the needs of circulating heat dissipation and ensure that the cooling mechanism has sufficient coolant during long-term operation. It is installed on the rear side of the interior of housing 1, away from heat-generating or sensitive components such as LED light panel 2 and communication module 17, so as to avoid the coolant temperature in the reservoir being affected by other components. At the same time, it does not occupy the installation space of core components, and makes reasonable use of the internal space of housing 1, so as to make the device structure layout compact.

[0073] Vent 9: Fixedly connected to the top of the coolant reservoir 8, it is the channel for gas to be discharged from the reservoir. The top position allows the gas generated in the reservoir to naturally accumulate and be discharged through vent 9, preventing gas from accumulating at the bottom of the reservoir or in the pipeline and forming air blockage. Air blockage will hinder the circulation of coolant and affect the heat dissipation efficiency. The setting of vent 9 can eliminate this problem, ensure smooth circulation of coolant, and maintain the stable heat dissipation effect of the cooling mechanism.

[0074] One-way exhaust valve 10: Fixedly connected to exhaust port 9, model PV01-EX; the advantage of this setting is that it has a one-way conduction function, allowing only the gas in the coolant reservoir 8 to be discharged through the exhaust port 9, which can prevent external air, dust, and water droplets from entering the reservoir through the exhaust port 9 and contaminating the coolant, or causing coolant leakage; at the same time, it can automatically respond to changes in the gas pressure in the reservoir, and automatically open the exhaust when the gas pressure reaches a certain value, without manual operation, ensuring the continuous and stable operation of the cooling mechanism and reducing maintenance needs;

[0075] Outlet 11: Fixedly connected to the left side of the coolant reservoir 8, it is the interface for coolant to flow out of the reservoir; the left side installation position matches the input end position of the micro water pump 13, which facilitates connection of the micro water pump 13 through the rubber hose 16, shortens the pipeline length, and reduces heat loss of coolant during transmission; at the same time, the interface design of outlet 11 can ensure a tight connection with the rubber hose 16, prevent coolant leakage, ensure the sealing of the coolant circulation path, and maintain the heat dissipation efficiency of the cooling mechanism;

[0076] Inlet 12: Fixedly connected to the left side of the coolant reservoir 8, adjacent to the outlet 11, it is the interface for coolant to flow back to the reservoir. Installed on the same side as the outlet 11, it allows for a more compact pipe layout of the cooling mechanism, avoids pipes crossing and tangling inside the housing 1, and saves installation space. At the same time, the inlet 12 corresponds to the output end of the water cooling head 7. After being connected through the rubber tube 16, it allows the coolant that has absorbed heat to flow back to the reservoir quickly, shortening the circulation path, improving heat dissipation efficiency, and the interface design ensures tight pipe connection to prevent coolant leakage.

[0077] Miniature water pump 13: Fixedly connected to the output end of the fixed bracket 15, model DC30-01-EX, is the power source for coolant circulation in the cooling mechanism; it is installed at the bottom of the housing 1 through the fixed bracket 15, ensuring a stable position and preventing pipe detachment due to vibration during operation; as a power source, it can drive coolant to flow out from the outlet 11 of the storage tank, and after absorbing heat through the water cooling head 7, it flows back to the inlet 12, forming a circulation for heat dissipation. Its model characteristics are adapted to the power consumption requirements of the device, providing sufficient circulation power without consuming too much energy, thus balancing heat dissipation and battery life.

[0078] Drive motor 14: Installed inside housing 1, with its bottom end fixedly connected to mounting bracket 15, is a ZYTD-38SRZ-EX type DC micro motor used to drive the micro water pump 13. It is powered by a 12V DC power supply, compatible with the device's battery voltage, eliminating the need for additional step-down equipment and simplifying the circuit structure. Its linkage installation with the micro water pump 13 via mounting bracket 15 ensures stable power transmission, driving the micro water pump 13 to operate efficiently and providing continuous power for coolant circulation. Furthermore, the motor's small size minimizes its internal space within housing 1, meeting the device's lightweight requirements.

[0079] Fixed bracket 15: Fixedly connected to the bottom of the inner part of the housing 1, with the drive motor 14 fixed at the top and the micro water pump 13 fixed at the output end; as a mounting support component for the drive motor 14 and the micro water pump 13, it can ensure that the two maintain a relatively fixed position during operation, avoid the motor and water pump from being misaligned or the pipes from falling off due to vibration, and ensure the stability of the cooling mechanism; at the same time, the structural design of the fixed bracket 15 can disperse the vibration generated by the motor and water pump during operation, reduce the impact of vibration on other components inside the housing 1, improve the overall operating stability of the device, and extend the service life of the components;

[0080] Rubber tube 16: Connected between the input end of the micro water pump 13 and the outlet 11, the output end of the micro water pump 13 and the input end of the water cooling head 7, and the output end of the water cooling head 7 and the inlet 12, respectively, it is the transmission pipeline for coolant circulation; the rubber material has good flexibility and sealing performance, which can adapt to the installation path inside the housing 1, flexibly connect various components, and avoid the pipeline being unable to adapt to the installation position due to excessive rigidity; at the same time, the strong sealing performance can prevent coolant leakage during transmission and ensure the integrity of the circulation path; in addition, the rubber tube 16 has a certain temperature resistance, which can adapt to the temperature change of the coolant and will not age or be damaged due to temperature fluctuations, ensuring the long-term stable operation of the cooling mechanism.

[0081] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
