[0031] The explosion-proof battery box for oilfield mines proposed by the present utility model includes:

[0032] A cylindrical plug 10, the cylindrical plug 10 having a power connection terminal 101; and

[0033] A battery box 20, the battery box 20 including a housing 201, a battery cell module 202, and a power connection joint 203. The battery cell module 202 is disposed inside the housing 201, and the power connection joint 203 is electrically connected to the battery cell module 202;

[0034] Wherein, a rotary buckle 102 is provided on one side of the power connection terminal 101 of the cylindrical plug 10, and the power connection joint 203 is provided with a lock that fits the rotary buckle 102, and the rotary buckle 102 is snap-fitted with the lock.

[0035] In the technical solution of the present utility model, the cylindrical plug 10 of the explosion-proof battery box for oilfield mines is provided with a rotary buckle 102, and the power connection joint 203 is provided with a lock. After the cylindrical plug 10 is inserted into the power connection joint 203 and the cylindrical plug 10 is rotated by a certain angle, the rotary buckle 102 is turned into the lock, and the fixed connection between the cylindrical plug 10 and the power connection joint 203 is completed. In this way, it will not loosen in environments such as severe vibration, impact, and drop, ensuring that the power connection contacts will not generate electric arcs to ignite external gases, thereby improving the safety performance of the battery box 20.

[0036] Please refer to Figures 1 to 5, the cylindrical plug 10 includes a wiring terminal 103 and a power connection terminal 101 provided at both ends of the plug housing. The wiring terminal 103 can be connected to a wire and pulled to an electrical device. The power connection terminal 101 includes three cylindrical power connection pin needles. The plug housing can be made of high-strength engineering plastics, such as polyamide (nylon) or polycarbonate. These engineering plastics can provide a certain mechanical strength for the plug housing and also have good corrosion resistance and wear resistance. In addition, in order to improve the waterproof performance of the cylindrical plug 10, a rubber sealing ring is used to ensure reliability in a humid or immersed environment.

[0037] The battery box 20 can provide power for the electrical device. The cylindrical plug 10 is inserted into the power connection joint 203 through three power connection pin needles to achieve power connection with the battery cell module 202. Among them, the outer shell 201 encloses a receiving space, and structures such as the wiring of the battery box 20 and the battery cell module 202 are arranged in the receiving space; the battery cell module 202 includes multiple battery cells and components such as a battery management system connected in series and parallel. The battery cell module 202 is hermetically arranged in the inner cavity of the outer shell 201 and is electrically connected to the battery management system to ensure the safe, efficient, and long-life operation of the battery box 20; the power connection joint 203 includes a power connection outer box and a power connection module. The power connection outer box is fixedly arranged on the outer shell 201 of the battery box 20, and the power connection module is fixedly arranged in the power connection outer box. The power connection module is electrically connected to the battery cell module 202 through a wire. In this way, after the battery box 20 is started and the cylindrical plug 10 is inserted into the power connection joint 203, the power supply demand of the electrical device can be satisfied. Specifically, the power connection joint 203 includes three jacks adapted to the power connection pin needles. One of the three jacks is used for grounding, and the other two are connected to the battery cell module 202 through wires to achieve electrical conduction.

[0038] Further, to ensure that there is no looseness and generation of electric sparks between the cylindrical plug 10 and the battery box 20 during use in a relatively harsh environment, a rotary buckle 102 is provided on the side of the power connection terminal 101 facing the power connection joint 203 of the cylindrical plug 10, and the power connection joint 203 is provided with a lock adapted to the rotary buckle 102. After the power connection terminal 101 is inserted into the power connection joint 203, because the shape of the power connection terminal 101 is cylindrical, the cylindrical plug 10 can be rotated counterclockwise or clockwise to insert the rotary buckle 102 into the lock, realizing the snap-fit between the two. Among them, the rotation angle of the cylindrical plug 10 is preferably 30°.

[0039] In an embodiment of the present utility model, please refer to Figure 2 , the power connection joint 203 includes two oppositely arranged rotary buckles 102, and each rotary buckle 102 is snap-fitted with the lock. In this way, the connection stability between the cylindrical plug 10 and the power connection plug can be further improved.

[0040] Further, please refer toFigure 2 The battery box 20 further includes a connector shielding cover 204. The connector shielding cover 204 is flexibly connected to the housing 201 and is configured to cover the power connection joint 203. Herein, the flexible connection can be understood as that the connector shielding cover 204 is provided on the housing 201 through a connection medium, and the connector shielding cover 204 can move to the position of the power connection joint 203 under the drive of an external force. Among them, the connection medium can be a traction rope assembly. When the power connection joint 203 does not need to be covered, the traction rope assembly pulls back the connector shielding cover 204 to its original position (i.e., the position where the connector shielding cover 204 is placed and fixed). Thus, by setting the connector shielding cover 204, it can prevent external combustible media (such as combustibles like gas and kerosene) from entering the interior of the battery box 20 or adhering to the power connection joint 203, thereby improving the safety performance of the explosion-proof battery box for oilfield mines.

[0041] In another embodiment, please refer to Figure 2 The battery box 20 is provided with a connecting member 205. One end of the connecting member 205 is connected to the housing 201, and the other end is connected to the connector shielding cover 204. The connecting member 205 can be a plastic rope with a certain elasticity or a necklace structure with an electrical isolation coating.

[0042] In an embodiment of the present utility model, please refer to Figure 2 There is an electrical isolation layer 206 between the battery cell module 202 and the housing 201. Thus, the battery cell module 202 is sealed in the housing 201, effectively preventing the battery cell module 202 from coming into contact with combustible media and avoiding explosion problems.

[0043] In an embodiment of the present utility model, please refer to Figure 2 There is an encapsulation space between the battery cell module 202 and the housing 201. The encapsulation space is filled with liquid silicone, and the liquid silicone forms the electrical isolation layer 206. Specifically, before the housing 201 of the battery box 20 is completely encapsulated, liquid silicone is poured into the encapsulation space between the housing 201 and the battery cell module 202. The liquid silicone can cover the circuits inside the housing 201 and cover the battery cell module 202. Then, after a certain period of time, the liquid silicone solidifies to form the electrical isolation layer 206. By pouring the liquid silicone, the insulation and heat conductivity of the battery box 20 are effectively improved. And after pouring the liquid silicone, the gas inside the housing 201 is discharged or there is only a small amount of air. Thus, even if the battery cell module 202 accidentally catches fire, it will automatically go out within a very short time due to the lack of a combustion-supporting agent (oxygen in the air), ensuring the safety performance of the battery box 20 and preventing explosion problems.

[0044] In an embodiment of the present utility model, please refer to Figure 2The battery box 20 also includes an electrical switch 207, which is electrically connected to the battery cell module 202. The electrical switch 207 and the electrical connector 203 are arranged on the same side of the shell 201. The electrical switch 207 is used to control the charging and discharging process of the battery box 20, and can also cut off the power supply to protect the battery box 20 and electrical equipment.

[0045] Furthermore, the battery cell material of the battery cell module 202 is lithium iron phosphate material.

[0046] In one embodiment of the present invention, the battery box 20 also includes a battery management system module, which is disposed at the end of the battery cell module 202. By providing the battery management system module, the battery box 20 is ensured to operate safely, efficiently and with a long life.

[0047] In one embodiment of the present invention, please refer to Figure 2 The battery box 20 also includes a handle 209, which is rotatably arranged on one side of the shell 201 and is staggered to connect the power connector 203, so that it is convenient to move the oilfield and mine explosion-proof battery box and realize multi-scene use.

[0048] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
