Description

Technical Field

[0001] This utility model relates to the field of mining lamp technology, specifically a charging rack structure for coal mine lamps. Background Technology

[0002] Mining lamps are a general term for specialized lighting fixtures used in mines, often shortened to mining lamps or industrial lamps. Tongming Electric's mining lamps are suitable for use in coal mines where there is a risk of gas and coal dust explosions; in mine roadways at the bottom of the shaft; and also in mine roadways and chambers with significant water seepage. Main uses: for safe lighting and emergency rescue lighting in environments with flammable and explosive gases, such as mines, petroleum, chemical, railway, transportation, and warehousing facilities. When the mining lamp's battery is depleted, it is recharged using a charging rack. Simply place the lamp in the corresponding charging compartment and connect it to a power source.

[0003] Currently, conventional coal mine lamp charging racks mostly rely on mains power for operation. When the mains power is interrupted, the lamps cannot be charged, affecting normal use. Furthermore, a large amount of heat is generated inside the cabinet during the charging process. This heat is difficult to dissipate and can easily cause short circuits and fires. If the fires cannot be extinguished in time, they pose even greater safety hazards. Therefore, we have proposed a coal mine lamp charging rack structure to solve the above problems.

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. Example

[0015] like Figures 1-4 As shown in the figure, an embodiment of the present invention provides a coal mine lamp charging rack structure, including a cabinet 1. A charging storage compartment 2 is fixedly installed on the front side wall of the cabinet 1 near the middle position, and the rear side wall of the charging storage compartment 2 is a mesh structure. A power supply mechanism 3 is arranged inside the cabinet 1 near the left side position. A first cabinet door 4 is hinged to the front side of the cabinet 1 corresponding to the power supply mechanism 3. A fabric covering mechanism 5 is arranged on the rear inner wall of the cabinet 1. The fabric covering mechanism 5 is connected to a fire extinguishing mechanism 6 and a cooling mechanism 7 respectively. The fire extinguishing mechanism 6 and the cooling mechanism 7 are installed inside the cabinet 1 near the right edge position. A second cabinet door 8 is hinged to the front side of the cabinet 1 corresponding to the fire extinguishing mechanism 6 and the cooling mechanism 7.

[0016] like Figure 2As shown, in some embodiments, the power supply mechanism 3 includes a controller 301, a relay 302, a mains power connector 303, a battery 304, a current sensor 305, and a charger 306. The controller 301, relay 302, mains power connector 303, battery 304, and current sensor 305 are all installed inside the cabinet 1. The controller 301 is electrically connected to the mains power connector 303 and the battery 304 respectively through the relay 302. The mains power connector 303 is provided with a current sensor 305. The mains power connector 303 is electrically connected to the battery 304 through the charger 306. The controller 301 is electrically connected to the charging storage compartment 2.

[0017] In this embodiment, the mains power connector 303 is powered by the controller 301 via the relay 302. The controller 301 is powered by the charging storage compartment 2, the fire extinguishing mechanism 6, and the cooling mechanism 7. When the current sensor 305 detects that there is no mains power, the controller 301 enables the battery 304 to be powered by the relay 302. The mains power connector 303 charges the battery 304 via the charger 306.

[0018] like Figure 1 As shown, in some embodiments, an operation display screen 9 is fixedly installed on the front side of the first cabinet door 4, corresponding to the controller 301.

[0019] In this embodiment, the operation display screen 9 is used to operate the charging rack, such as opening and closing.

[0020] like Figure 3 As shown, in some embodiments, the fabric distribution mechanism 5 includes a fabric distribution pipe 501, a branch pipe 502, and a nozzle 503. The fabric distribution pipe 501 is installed on the rear inner wall of the cabinet 1. The branch pipe 502 is evenly distributed on the left side of the fabric distribution pipe 501. The branch pipe 502 is installed on the rear inner wall of the cabinet 1. The nozzle 503 is evenly distributed on the front side of the branch pipe 502.

[0021] In this embodiment, the material in the cloth pipe 501 flows into the branch pipe 502, and then is sprayed through the branch pipe 502 onto the power supply mechanism 3 and the charging storage compartment 2 for cooling or fire extinguishing.

[0022] like Figure 3 As shown, in some embodiments, the fire extinguishing mechanism 6 includes a fire extinguisher 601, a conduit 602, a solenoid valve 603, a first check valve 604, and a smoke sensor 605. The fire extinguisher 601 is installed on the inner right side wall of the cabinet 1. The outlet of the fire extinguisher 601 is connected to the fabric distribution pipe 501 through the conduit 602. The solenoid valve 603 and the first check valve 604 are installed sequentially on the conduit 602. The smoke sensor 605 is installed on the inner rear wall of the cabinet 1.

[0023] In this embodiment, when the smoke sensor 605 detects fire smoke inside the cabinet 1, it feeds the information back to the controller 301. The controller 301 opens the solenoid valve 603, and the extinguishing material in the fire extinguisher 601 flows into the distribution pipe 501 through the conduit 602. The material in the distribution pipe 501 flows into the branch pipe 502, and then is sprayed through the branch pipe 502 towards the power supply mechanism 3 and the charging storage compartment 2 to extinguish the fire.

[0024] like Figure 3 As shown, in some embodiments, the cooling mechanism 7 includes a fan 701, a semiconductor refrigeration box 702, a dehumidification box 703, a first connecting pipe 704, a second check valve 705, a second connecting pipe 706, a return air pipe 707, and a temperature and humidity sensor 708. The fan 701, the semiconductor refrigeration box 702, and the dehumidification box 703 are installed sequentially from top to bottom on the right inner wall of the cabinet 1. The air outlet of the fan 701 is connected to the fabric pipe 501 through the first connecting pipe 704. The second check valve 705 is installed on the first connecting pipe 704. The fan 701, the semiconductor refrigeration box 702, and the dehumidification box 703 are connected through the second connecting pipe 706. The air inlet of the dehumidification box 703 is equipped with a return air pipe 707, which is installed on the rear inner wall of the cabinet 1.

[0025] In this embodiment, when the temperature and humidity sensor 708 detects that the temperature and humidity inside the cabinet 1 are greater than the set value, it feeds the information back to the controller 301. The controller 301 then turns on the fan 701 and the semiconductor cooling box 702. The fan 701 draws dry air from the dehumidification box 703 into the semiconductor cooling box 702 for cooling through the second connecting pipe 706. The dry, low-temperature air flows into the distribution pipe 501 through the first connecting pipe 704. The low-temperature, dry air in the distribution pipe 501 flows into the branch pipe 502, and then through the branch pipe 502... The gas is sprayed towards the power supply mechanism 3 and the charging storage compartment 2 to cool them down. The high temperature and high humidity gas in the cabinet 1 flows into the dehumidification box 703 through the air hole on the return air pipe 707 for circulation. The semiconductor cooling box 702 consists of a box body and a semiconductor cooler. The semiconductor cooler is embedded in the right side wall of the box body. The cooling is performed in the box body through the cooling surface on the left side of the semiconductor cooler. The opening structure on the right side of the box body meets the heat exchange requirements of the heat dissipation fins and cooling fan on the right side of the semiconductor cooler. The right side of the box body is located in the right side wall of the cabinet 1 to meet the heat exchange requirements.

[0026] During use, open the small cabinet door corresponding to the charging storage compartment 2, place the miner's lamp inside to charge, and power the mains connector 303 in the power supply mechanism 3 through the relay 302 to the controller 301. The controller 301 powers the charging storage compartment 2, the fire extinguishing mechanism 6, and the cooling mechanism 7. When the current sensor 305 detects no mains current, the controller 301 powers the battery 304 through the relay 302, and the mains connector 303 charges the battery 304 through the charger 306. During use, if the temperature and humidity sensor 708 in the cooling mechanism 7 detects that the temperature and humidity inside the cabinet 1 are higher than the set value, it will send the information back to the controller 301. The controller 301 will then turn on the fan 701 and the semiconductor cooling box 702. The fan 701 will draw dry air from the dehumidification box 703 into the semiconductor cooling box 702 through the second connecting pipe 706 for cooling. The dry, low-temperature air will flow into the distribution pipe 501 through the first connecting pipe 704. Low-temperature, dry air flows into branch pipe 502 and is then sprayed onto the power supply mechanism 3 and charging storage compartment 2 for cooling. High-temperature, high-humidity gas inside the cabinet 1 flows into the dehumidification box 703 through the air vent on the return pipe 707 for circulation. If the smoke sensor 605 in the fire extinguishing mechanism 6 detects fire smoke inside the cabinet 1, it sends the information to the controller 301. The controller 301 opens the solenoid valve 603, and the extinguishing material in the fire extinguisher 601 flows into the distribution pipe 501 through the conduit 602. The material in the distribution pipe 501 flows into branch pipe 502 and is then sprayed onto the power supply mechanism 3 and charging storage compartment 2 to extinguish the fire. If a fire is extinguished, the charging rack needs to be disassembled and inspected, and the distribution mechanism 5 needs to be cleaned. This allows the mining lamp charging rack to continue charging the mining lamp even when the mains power is cut off, increasing the cooling and dehumidification function inside the cabinet 1, effectively preventing situations such as charging height or short circuits, and enabling it to extinguish fires autonomously, greatly reducing safety hazards during use.

[0027] In summary, this coal mine lamp charging rack structure, through the power supply mechanism 3, has two power supply modes: mains power and battery 304. It can continue to charge the lamp even when the mains power is interrupted, and adds the function of cooling and dehumidifying inside the cabinet 1. It effectively avoids situations such as charging height or short circuits, and can automatically extinguish fires, greatly reducing safety hazards during use.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
