At the same time, the explosion-proof casing is adopted to ensure safe operation even in harsh environments. BRIEF DESCRIPTION OF THE DRAWINGS

The phrase does not necessarily refer to the same embodiment each time it appears in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0028] An embodiment of the present invention provides an explosion-proof battery power supply, as Figure 1-7 shown, the explosion-proof battery power supply includes: a base 1 and a connection frame mounted on the base 1; a battery body 2 disposed within the connection frame; a circuit breaker 3, a transformer 4, and an isolation amplifier 5 all mounted on one side of the connection frame, and the battery body 2, the transformer 4, and the isolation amplifier 5 are all electrically connected to the circuit breaker 3; an explosion-proof enclosure 6 mounted on the base 1, and the explosion-proof enclosure 6 covers the battery body 2, the circuit breaker 3, the transformer 4, and the isolation amplifier 5; a lid 7 hinged to the explosion-proof enclosure 6; a monitoring mechanism provided on the lid 7 for monitoring the temperature of the battery body 2; and an auxiliary heat dissipation mechanism provided on the explosion-proof enclosure 6 for assisting the battery body 2 in heat dissipation.

[0029] In this embodiment, the electrical connection design between the battery body 2, the transformer 4, the isolation amplifier 5 and the circuit breaker 3 not only ensures the stable transmission of electric energy, but also realizes the rapid cut-off protection of the circuit through the circuit breaker 3, preventing safety accidents caused by electrical faults. The isolation amplifier 5 is used for signal processing or isolation to enhance the electrical safety of the system. At the same time, the explosion-proof enclosure 6 covering the battery body 2, the circuit breaker 3, the transformer 4 and the isolation amplifier 5 effectively isolates the potential threats of the external environment to the internal electrical components, such as moisture, dust, mechanical impact, etc. More importantly, under extreme conditions (such as overcharging, over-discharging, extrusion, collision, heating of the battery), the explosion-proof enclosure 6 can prevent the internal components from catching fire and exploding, ensuring the safety of underground operations. The explosion-proof enclosure 6 effectively isolates the internal electrical components from the external environment. Especially in the special environment of coal mines, it can prevent the occurrence of dangerous situations such as sparks and explosions, ensuring the safety of personnel and equipment.

[0031] In this embodiment, when the battery body 2 is operating, the heat generated by the battery body 2 is transferred to the detection probe of the temperature and humidity sensor 10 through the heat conducting rod 11, so that the temperature and humidity sensor 10 monitors the temperature of the battery body 2. When the temperature of the battery body 2 is higher than a certain value, the auxiliary heat dissipation mechanism is automatically started, and the auxiliary heat dissipation mechanism performs auxiliary heat dissipation operation on the battery body 2, thereby performing air cooling on the battery body 2 to ensure the safety of the battery body 2 during use. By monitoring the temperature of the battery body 2 through the temperature and humidity sensor 10, it is convenient to perform heat dissipation operation on it in a timely manner subsequently. At the same time, the working state of the battery body 2 can be understood in a timely manner, and potential safety hazards caused by overheating can be prevented. Once the temperature is abnormal, measures can be taken in a timely manner to avoid accidents.

[0032] In a further preferred embodiment of the present utility model, the auxiliary heat dissipation mechanism includes: a rectangular frame 12 fixedly installed on one side of the explosion-proof enclosure 6; heat dissipation openings 13 and heat dissipation holes respectively opened on both sides of the explosion-proof enclosure 6, and the heat dissipation opening 13 is communicated with the rectangular frame 12; a heat dissipation fan 14 fixedly installed in the rectangular frame 12; a group of filter screens 15 respectively arranged on one side of the rectangular frame 12 and the heat dissipation hole.

[0033] In this embodiment, when the temperature of the battery body 2 is too high and heat dissipation treatment is required, the cooling fan 14 is first started to blow air into the explosion-proof housing 6, so as to discharge the hot air in the explosion-proof housing 6 outside the housing 6 and perform air cooling operation on the battery body 2. When performing air cooling operation on the battery body 2, a set of filter screens 15 isolate impurities or water vapor in the external environment, so as to ensure that they will not be discharged into the housing 6. By isolating external impurities or water vapor through the filter screens 15, it is ensured that they will not come into contact with the battery body 2, which is beneficial to improving the operating safety of the battery body 2.

[0034] In a further preferred embodiment of the present invention, a T-shaped rod 16 is fixedly installed on one side of the filter screen 15, and a limiting plate 17 is fixedly installed on one side of the explosion-proof housing 6.

[0035] In this embodiment, when installing the filter screen 15, first insert the T-shaped plate 16 into the limiting plate 17, and the assembly operation of the filter screen 15 can be completed. By slidably connecting the T-shaped plate 16 with the limiting plate 17, the filter screen 15 can be quickly loaded and unloaded, and the operation is relatively fast.

[0036] In a further preferred embodiment of the present invention, an installation box 18 is fixedly installed on one side of the explosion-proof housing 6.

A clamping block 19 is fixedly installed on the top of the slider, and the clamping block 19 is in sliding contact with the top end of the T-shaped rod 16.

[0037] In this embodiment, before assembling the filter screen 15, first pull the clamping block 19 to drive the slider to slide along the sliding rod, so that the clamping block 19 presses the return spring and compresses the return spring, so that the clamping block 19 slides away from above the limiting plate 17. Then install the filter screen 15 on the limiting plate 17. After installation, release the clamping block 19 to release the return spring and spring the clamping block 19 into the upper part of the T-shaped rod 16 to perform a limiting operation on the T-shaped rod 16. By limiting the T-shaped rod 16 with the clamping block 19, it is ensured that the T-shaped rod 16 is stable in the limiting plate 17, and the limiting effect is good. At the same time, it is also beneficial to the subsequent disassembly operation of the filter screen 15.

[0038] In a further preferred embodiment of the present invention, a U-shaped plate is fixedly installed at the bottom of the inner wall of the rectangular frame 12. The U-shaped plate is in sliding contact with the filter screen 15. A clamping plate is rotatably installed at the top of the rectangular frame 12. The clamping plate is in rotational contact with the top of the filter screen 15. A sealing strip is assembled on the filter screen 15 away from the rectangular frame 12, and the sealing strip is in close contact with the explosion-proof housing 6.

[0039] In this embodiment, the filter screen 15 in the rectangular frame 12 is fixed by a clamping plate to ensure that the filter screen 15 does not separate from the rectangular frame 12, and the positioning effect is good. At the same time, through the setting of the sealing strip, it is ensured that external dust or impurities do not enter the explosion-proof housing 6 through the connection notch of the filter screen 15, and the sealing effect is good.

[0040] In a further preferred embodiment of the present invention, a U-shaped block 20 is fixedly installed on the explosion-proof housing 6, a connecting block 21 is fixedly installed on one side of the lid 7, the connecting block 21 is in contact with the U-shaped block 20, a positioning rod 22 is slidably installed on the U-shaped block 20, and the positioning rod 22 slidably penetrates through the connecting block 21.

[0041] In this embodiment, when it is necessary to open the lid 7, first remove the positioning rod 22 from the U-shaped block 20, and then the lid 7 can be opened. Since a connecting rope is provided on one side of the housing 6 and the connecting rope is connected to the positioning rod 22, when the positioning rod 22 is separated from the U-shaped block 20, the positioning rod 22 will not be lost. The lid 7 is fixed by the positioning rod 22 to ensure that the lid 7 does not move randomly, and the fixing is relatively convenient.

[0042] In a further preferred embodiment of the present invention, a connecting groove is formed at the bottom of the positioning rod 22, a connecting spring is fixedly installed in the connecting groove, a positioning block 23 is installed at the bottom end of the connecting spring, the positioning block 23 slidably extends out of the connecting groove, and the positioning block 23 is in sliding contact with one side of the U-shaped block 20.

[0043] In this embodiment, the positioning rod 22 is limited by the positioning block 23 to ensure that the positioning rod 22 does not separate from the U-shaped block 20, and the limiting effect is good.
