[0005] Therefore, it is necessary to provide a mine explosion -proof type booster substation. UTILITY MODEL CONTENTS

[0006] The mine explosion -proof type booster substation provided by the embodiment of the present application can improve the problem that the mine explosion -proof type booster substation lacks redundant design in the heat dissipation system in the related art, so that the equipment cannot be cooled immediately after the heat dissipation system fails due to dust blockage or fan failure, causing the equipment to overheat and causing safety hazards.

[0023] Based on this, in order to improve the problem that the heat dissipation system of the explosion-proof step-up substation for mining in the relevant technology lacks redundancy design, which may cause the heat dissipation system to fail due to dust blockage or fan failure, and thus cannot immediately cool down the equipment, resulting in overheating and safety hazards, the embodiments of this application provide the following solution.

[0024] Please refer to the following: Figures 1-3 The system includes a substation body 1, a cap 2, and a heat dissipation mechanism 3. The substation body 1 includes a transformer 4. The heat dissipation mechanism 3 includes a monitoring feedback component 31, a radiator 32, a fan 33, a standby fan 34, and a temperature sensor 35. The cap 2 is fixedly connected to the substation body 1. The transformer 4 is fixedly connected inside the substation body 1. The radiator 32 is fixedly connected to the transformer 4. The temperature sensor 35 is fixedly connected inside the substation body 1. The cap 2 has ventilation holes 5. The fan 33 and the standby fan 34 are rotatably connected to the cap 2 and cool the inside of the substation body 1 through the ventilation holes 5. The cap 2 has four fans 33 and two standby fans 34, arranged on both sides of the cap 2 with one standby fan 34 sandwiched between two fans 33. The monitoring feedback component 31 is fixedly connected to the side of the cap 2 closest to the inside of the substation body 1, and the fans 33 and the standby fans 34 are connected by signals through the monitoring feedback component 31.

[0025] With this configuration, the radiator 32 is directly connected to the transformer 4, enabling rapid conduction and dissipation of the heat generated during transformer 4 operation, thus improving heat dissipation efficiency. The fan 33 and the backup fan 34 provide dual protection. Through the combination of active cooling (fan 33) and backup cooling (backup fan 34), the cooling effect is maintained even when the main fan 33 fails, preventing overheating of the equipment due to insufficient cooling. When the fan 33 fails, the monitoring feedback component 31 receives the relevant signal and starts the backup fan 34 to ensure the continuous operation of the cooling system and prevent equipment shutdown due to a single fault. The temperature sensor 35 monitors the internal temperature of the substation body 1 in real time, providing data support for the cooling system. When the temperature inside the substation body 1 is detected to be high, the fan speed of the fan 33 is increased; conversely, the fan speed of the fan 33 is reduced when the temperature is low, achieving intelligent temperature control while realizing energy saving and emission reduction. The fan 33, the backup fan 34, and the monitoring feedback component 31 are concentrated on the top of the cap 2, facilitating inspection and replacement and reducing maintenance time and costs.

[0026] Optionally, in some embodiments, please also refer to Figure 3 The monitoring feedback component 31 includes a speed sensor 311, a signal processor 312, and an alarm light 313. The speed sensor 311 is installed inside the fan 33, and the signal processor 312 and the alarm light 313 are both installed on the top of the cap 2. The speed sensor 311 and the signal processor 312 are electrically connected, and the signal processor 312 is electrically connected to the spare fan 34 and the alarm light 313.

[0027] With this configuration, the speed sensor 311 monitors the rotation of the fan 33 in real time. When the fan 33 experiences a decrease in speed or stops completely due to mechanical failure, power supply problems, or other reasons, the speed sensor 311 immediately detects this abnormal state and identifies it as a fan 33 malfunction. Subsequently, the speed sensor 311 transmits the fault information to the signal processor 312 in the form of an electrical signal. Upon receiving the fault signal, the signal processor 312 quickly analyzes and processes it, triggering the following two operations: firstly, the signal processor 312 sends a start command to the standby fan 34, causing it to start operating immediately and take over the work of the malfunctioning fan 33; secondly, the signal processor 312 activates the alarm light 313 installed outside the substation or on the control panel, emitting a conspicuous visual warning signal. This visual warning can quickly attract the attention of staff, reminding them to promptly check the specific cause of the fan 33 malfunction and take appropriate maintenance or repair measures.

[0028] Optionally, in some embodiments, please also refer to Figure 2 as well as Figure 4 The substation body 1 is equipped with an explosion-proof enclosure 6. The explosion-proof enclosure 6 has an explosion-proof groove, which is filled with explosion-proof material. The surface of the explosion-proof enclosure 6 is coated with an anti-corrosion and anti-rust coating to adapt to the humid environment of the mine.

[0029] With this configuration, the explosion-proof enclosure 6 is made of either steel plate or cast steel, and the explosion-proof material is one or more of quartz sand, ceramic particles, epoxy resin, and polyurethane. Quartz sand has a high melting point and good thermal conductivity, which can absorb explosion energy and reduce explosion pressure. Ceramic particles are resistant to high temperature and corrosion, and can effectively absorb and disperse explosion energy. Epoxy resin and polyurethane have excellent explosion-proof and insulation properties. The surface of the explosion-proof enclosure 6 is coated with an anti-corrosion and anti-rust coating, which effectively prevents metal surface corrosion and rust, extends the service life of the equipment, and at the same time reduces the occurrence of corrosion and rust, reduces the frequency of maintenance and replacement, and saves costs.

[0030] Optionally, in some embodiments, please also refer to Figure 1 A dustproof net 7 is provided on the top of the cap 2, and the dustproof net 7 covers the fan 33 and the spare fan 34.

[0031] With this setup, the high concentration of dust particles in the mine environment can cause problems such as short circuits and poor contact when they enter. Dust accumulation can also hinder heat dissipation, leading to equipment overheating. The dustproof net 7 blocks dust while ensuring good ventilation and heat dissipation. Therefore, the dustproof net 7 plays a key protective role in the explosion-proof step-up substation for mines, ensuring stable operation of the equipment in harsh environments.

[0032] Optionally, in some embodiments, please also refer to Figure 2 The radiator 32 has multiple fins 8, and the heat pipe channels of the radiator 32 are made of copper.

[0033] With this configuration, fin 8 is mainly used to increase the heat dissipation area and improve heat dissipation efficiency. Copper is used as the material for the heat pipe because copper has excellent thermal conductivity, which can quickly transfer heat. Copper also has good corrosion resistance, making it suitable for various environments. Furthermore, copper pipes have high mechanical strength and good durability.

[0034] Optionally, in some embodiments, please also refer to Figure 4 The substation body 1 is equipped with a lighting lamp 9, which has the function of adjusting the brightness and color of the lighting.

[0035] This setup allows changes in lighting color to influence mood and concentration. For example, warm-toned lighting can create a cozy and comfortable atmosphere, helping to alleviate worker fatigue; while cool-toned lighting may make people more alert and focused. By adjusting the lighting color, the most suitable working environment can be created according to work needs or the psychological state of the workers, thereby improving work comfort and efficiency. Lighting is one of the most energy-intensive components in a substation. By adjusting the brightness and color of the lighting, energy consumption can be precisely controlled according to actual needs, avoiding unnecessary energy waste. When high-brightness lighting is not needed, the brightness can be appropriately reduced to decrease energy consumption; when long-term lighting is required, more energy-efficient lighting modes can be selected.

[0036] Optionally, in some embodiments, please also refer to Figure 4 The substation body 1 is also equipped with an integrated backup battery 10 to ensure that critical equipment continues to operate in the event of a power outage, thereby improving system reliability.

[0037] With this configuration, the integrated backup battery 10 can quickly switch to power supply when the main power supply fails or is interrupted, ensuring that critical equipment such as protection devices, automation equipment, and communication equipment can continue to operate, thereby maintaining the normal operation of the substation and the stability of the power system. This design avoids equipment paralysis and power outages caused by power failures, reduces losses caused by failures, and improves the reliability of the entire power system.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
