Description

Technical Field

[0001] This application relates to the field of explosion-proof boxes, specifically to an explosion-proof box for mining. Background Technology

[0002] In flammable, explosive, and other hazardous environments, electrical equipment is often equipped with explosion-proof enclosures to house heat-generating electrical components such as frequency converters, soft starters, power modules, thyristors, capacitors, and resistors. In mining operations, we frequently need to measure the liquid level in containers. For relatively stable liquids, ordinary level measuring probes are sufficient. However, for unstable liquids, such as oil, ordinary level measuring probes, due to their external circuitry, can potentially affect the stability of the liquid, leading to hazards such as explosions.

[0003] Therefore, we proposed a mine explosion-proof box to assist in the measurement of liquid level. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a mine explosion-proof box, thereby solving the problems existing in the prior art to a certain extent.

[0005] This invention provides a mine explosion-proof box, including a shell, a battery module, a motherboard module, an antenna module, a water pipe connector, and a sensor. A partition is provided inside the shell, dividing the space of the shell into a first mounting cavity and a second mounting cavity. The battery module is located in the first mounting cavity, and the motherboard module and the antenna module are located in the second mounting cavity. The water pipe connector is located at the bottom of the shell, with one end of the water pipe connector extending into the second cavity. The sensor is located inside the water pipe connector via a threaded plunger, and the sensing end of the sensor is longer than the end of the water pipe connector furthest from the shell.

[0006] Preferably, the motherboard module is mounted parallel to the inner wall of the second cavity by means of a first stud and a second stud, and the antenna module is fixed by a second stud and bolts to be parallel to the motherboard module. The motherboard module and the antenna module are stacked in the second cavity.

[0007] Preferably, the antenna module includes a mounting plate and an antenna, the mounting plate having an antenna receiving cavity, and the antenna being disposed within the antenna receiving cavity.

[0008] Preferably, the housing includes a square housing with an opening on one side and a housing cover plate, which are connected by fasteners.

[0009] Preferably, an embedding groove is formed on one side of the opening of the square shell, and a sealing rubber ring is provided in the embedding groove, the thickness of the sealing rubber ring being the same as the depth of the embedding groove.

[0010] Preferably, the explosion-proof box for mining further includes a battery cover, and the side of the opening of the first cavity is recessed in the inner side of the embedding groove, forming an installation area. The battery cover can be locked in the installation area, and the battery cover and the housing cover will not interfere with each other.

[0011] Preferably, the fixing holes of the housing cover and the square housing are arranged on the outside of the embedding groove.

[0012] Preferably, the square housing has a tempered glass protective cover on the side opposite to the cover plate, and an indicator light is provided below the tempered glass protective cover.

[0013] Preferably, the mining explosion-proof box further includes a push-button switch, which is disposed adjacent to the tempered glass protective cover.

[0014] Preferably, the partition has a long opening that passes through it, allowing the first installation space and the second installation space to communicate.

[0015] Beneficial effects: Compared with the prior art, the mine explosion-proof box provided in this application uses water pipe joints and sensors to accurately sense the liquid level, while the outer shell protects the internal structures such as the battery module and motherboard module that are prone to overheating. When the container is full of water, the top cover of the container is lifted up, and the top cover can contact the sensor to indicate that the container is full. The sensor can then start counting. The structure is simple, easy to operate, and eliminates the danger of explosions. Attached Figure Description

[0026] In flammable, explosive, and other hazardous environments, electrical equipment is often equipped with explosion-proof enclosures to house heat-generating components such as frequency converters, soft starters, power modules, thyristors, capacitors, and resistors. In mining operations, we frequently need to measure the liquid level in containers. For relatively stable liquids, ordinary level measuring probes are sufficient. However, for unstable liquids, such as oil, ordinary level measuring probes, due to their external circuitry, may affect the stability of the liquid, potentially leading to explosions or other hazards. Therefore, we have proposed a mining explosion-proof box to assist in measuring liquid levels.

[0027] like Figure 1-4 As shown, this application discloses a mine explosion-proof box, including a shell, a battery module 3, a motherboard module 4, an antenna module, a water pipe connector 7, and a sensor 8. The shell is provided with a partition 9, which divides the space of the shell into a first mounting cavity 10 and a second mounting cavity 11. The battery module 3 is located in the first mounting cavity 10, and the motherboard module 4 and the antenna module are located in the second mounting cavity 11. That is, the battery module 3 and the motherboard module 4 are respectively located in relatively independent cavities. The water pipe connector 7 is connected to the bottom of the shell, and one end of it connected to the shell extends into the second mounting cavity 11. The sensor 8 is located inside the water pipe connector 7 through a threaded plunger (not shown in the figure).

[0028] Preferably, the sensing end of the sensor 8 is longer than the end of the water pipe connector 7 that is furthest from the outer casing. The sensor 8 is a contact sensor and needs to have good waterproof performance. When the solution inside the container is full, the top cover can touch the sensing end of the sensor 8 after being pushed up by the solution.

[0029] Preferably, the partition 9 has a long opening that passes through it, which allows the first mounting cavity 10 and the second mounting cavity 11 to communicate and accommodate the wire harness or other wire harnesses connecting the battery module 3 and the motherboard module 4.

[0030] Preferably, the outer shell includes a square shell 1 with an opening on one side and a shell cover plate 2, which are connected by bolts. The side of the opening of the square shell 1 is provided with holes for installation and fixing. These holes are close to the outer edge and there are at least four holes, which are located at the four corners. In this embodiment, to increase the stability of the connection, there are six holes, with two extra holes located on the side. The holes on the shell cover plate 2 and the holes on the square shell 1 correspond to each other.

[0031] Preferably, to increase the sealing performance of the outer shell, an embedding groove 12 is provided on one side of the opening of the square shell 1. A sealing rubber ring (not shown in the figure) is provided in the embedding groove 12. It should be emphasized that the embedding groove 12 is located on the inner side of the hole. After the shell cover plate 2 and the square shell 1 are fixed, the sealing rubber ring just abuts against the shell cover plate 2.

[0032] Furthermore, referring to Figure 2 As shown, a tempered glass protective cover 13 is provided on the side of the square shell 1 away from the cover plate. An indicator light (not shown in the figure) is provided below the tempered glass protective cover 13. The tempered glass protective cover 13 is used to protect the indicator light from damage, while allowing the color change of the indicator light to be clearly seen. The mining explosion-proof box also includes a push-button switch 14, which is disposed on the square shell 1 adjacent to the tempered glass protective cover 13.

[0033] Preferably, four first studs 15 are provided on the inner wall of the second mounting cavity 11. The four first studs 15 need to be of the same length. The motherboard module 4 is located at one end of the first stud 15 and is fixed to one end of the first stud 15 by using second studs 16. The first stud 15 includes a rod body, an insertion end, and a slot. The insertion end and the slot are respectively located at both ends of the rod body. The insertion end is a threaded section, and the inner wall of the slot is threaded. The insertion end of one first stud 15 can mate with the slot of another first stud 15. The second stud 16 has the same structure as the first stud 15, and the dimensions of the first studs 15 and the second stud 16 used in this embodiment are also the same. In this embodiment, the insertion end of the first stud 15 is threadedly connected and fixed to the side wall of the second mounting cavity 11. The mounting holes provided on the four corners of the motherboard module 4 correspond exactly to the slots of the four first studs 15. The motherboard module 4 is fixed by using the insertion end of the second stud 16 and the slot of the first stud 15.

[0034] Furthermore, after the mainboard module 4 is fixed, the insertion holes of the second studs 16 extend outwards, and the four second studs 16 are of the same length, ensuring that the insertion holes of the four second studs 16 are on the same horizontal plane. The mounting holes of the antenna module can correspond one-to-one with the insertion holes of the second studs 16, and the antenna module is installed on the second studs 16 using bolts. The mainboard module 4 and the antenna module are stacked parallel to each other in the second mounting cavity 11, effectively improving the space utilization. The antenna module includes a mounting plate 5 and an antenna. The mounting plate 5 has an antenna receiving cavity 6, and the antenna is installed in the antenna receiving cavity 6.

[0035] Furthermore, the explosion-proof box for mining also includes a battery cover 18. The side of the opening of the first mounting cavity 10 is recessed inside the embedding groove 12, and the recessed part forms an installation interval 17. The battery cover 18 can be locked in the installation interval 17, and the battery cover 18 and the housing cover 2 will not interfere with each other.

[0036] Compared with existing technologies, the mine explosion-proof box provided in this application can accurately sense the liquid level by using water pipe connector 7 and sensor 8. When the container is full of water, the top cover of the micro switch on the container is lifted, and the top cover can contact the sensor 8 to indicate that the container is full. The sensor 8 can start counting. The structure is simple, easy to operate, and eliminates the occurrence of dangerous situations such as explosions.

[0037] The above description is only a preferred embodiment of the explosion-proof box for mining disclosed in this invention. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
