Description

Technical Field

[0001] The present invention relates to the technical field of chargers, and specifically to an underground explosion-proof charger for mines and its usage method. Background Art

[0002] Underground explosion-proof chargers for mines are charging devices designed specifically for mine environments. Their research and development and application backgrounds mainly stem from the urgent needs for mine operation safety, equipment stability, and reliable energy supply. The mine operation environment is complex and changeable, with dangerous factors such as explosive gases and dust. This requires electrical equipment used underground to have good explosion-proof performance to prevent explosion accidents caused by equipment failures or improper operations. The underground explosion-proof charger for mines is designed based on this need. It uses explosion-proof technology and can be safely used in the harsh mine environment.

[0003] For example, in the patent document with the prior art publication number CN220628937U, this patent document belongs to the technical field of battery charging, and specifically provides an underground lithium-ion battery charger for mines, including a first box body and a second box body. The interior of the first box body is separated by a partition into an electrical cavity and a wiring cavity. The electrical cavity is above the wiring cavity. An explosion-proof wiring terminal is installed through the partition. One end of the wiring terminal is in the electrical cavity, and the other end is in the wiring cavity. The second box body is fixed to one side of the first box body. One end of the second box body is open and connected to the rear cover of the first box body. A heat dissipation cavity is enclosed between the second box body and the rear cover. The charging gun has a charging plug that mates with the charging interface in the lithium-ion battery. The charging gun is connected to the cable connector at the lower part of the first box body through a cable. One end of the cable connector is outside the first box body, and the other end is inserted into the wiring cavity. There is a communication port at the rear cover that communicates the electrical cavity and the heat dissipation cavity. A main board is nested in the communication port. Electrical components are installed on the side of the main board facing the electrical cavity.

[0004] In the prior art, although the battery can be cooled by setting up heat dissipation plates, during actual use, complex chemical reactions occur when the battery is charging. Inevitably, heat is generated during this process, and this heat is non-uniformly distributed at different parts of the battery, forming high-frequency heat generation points. Unfortunately, most of the currently commonly used heat dissipation structures adopt a unified heat dissipation strategy and fail to accurately dissipate heat from these high-frequency heat generation points on the battery surface. This "one-size-fits-all" heat dissipation method is not only inefficient but also may lead to unreasonable distribution and use of coolant resources. Specifically, unified heat dissipation often means that when the coolant flows through the battery surface, it cannot effectively concentrate on cooling those high-frequency heat generation points that most need heat dissipation, thus preventing the full utilization of the heat dissipation potential of the coolant and affecting the overall heat dissipation effect and the utilization efficiency of the coolant. For this reason, this application proposes an underground explosion-proof charger for mines and its usage method. Summary of the Invention

[0007] A transition box, which is fixedly connected to one side of the housing, and a partition is arranged along its center inside it, dividing it into a liquid chamber and an input chamber. A plurality of inlet pipes are communicated inside the input chamber, and a plurality of outlet pipes are communicated inside the liquid chamber.

[0011] Preferably, both sides of the auxiliary cylinder are communicated with a pressure pipe, and a support cylinder is fixedly connected inside the pressure pipe.

[0012] Preferably, a cam is fixedly connected to one end of the movable copper pipe far from the positioning copper sheet. A top wheel in contact with the cam is rotatably connected to one end of the sliding rod far from the piston sheet, and a return spring for driving the sliding rod to reset itself is sleeved on the outer surface of the sliding rod.

[0013] Preferably, a plurality of rows of holes are opened inside the partition, a plurality of baffles for blocking the rows of holes are slidably connected to one side of the transition box, a cylinder is commonly connected to the plurality of baffles, and an output end of the cylinder is fixedly connected to the transition box.

[0016] Preferably, a box door is provided on a side of the shell away from the transition box, a rotating rod for driving the box door to rotate is fixedly connected to one end of the shell, and a junction box is fixedly connected to the top of the shell.

[0017] The present invention also provides a method for using an underground flameproof charger for mining, comprising the following steps:

[0018] S1. It can be connected to a plug for charging when in use;

[0019] S2. During charging, the battery will undergo a chemical reaction and generate a certain amount of heat. Turning on the cooling component can dissipate heat from the battery.

[0020] S3. As the local temperature of the battery gradually increases, the enhancement component will operate in coordination with the cooling component to improve the cooling effect, thereby suppressing the local temperature of the battery.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By setting the alternating use of centrifugal pump-driven air cooling and water cooling, the system can flexibly adjust the cooling method according to the heat generation situation of the battery. Air cooling is started during slight heating to save water resources; water cooling is started when the temperature is relatively high to ensure the cooling effect. The movable copper pipe, positioning copper sheet, hinged copper handle, and copper plate in the cooling component are all made of copper, which has excellent thermal conductivity and can quickly transfer the heat generated by the battery to the coolant or air for heat dissipation. Multiple water cavities are evenly attached to one side of the battery to monitor the heat generation situation at each location in real time. When the local temperature is too high, the evaporation of water vapor in the corresponding water cavity pushes the piston push rod to move, increasing the copper plate area in contact with this area to achieve precise heat dissipation and avoid battery damage caused by local overheating. The design of the movable copper pipe prevents external air from mixing into the shell during wind cooling, reduces the intrusion of dust and moisture, and improves the service life of the battery. The efficiency-enhancing component uses the evaporation of water vapor in the water cavity to push the piston push rod to move, which not only increases the heat conduction efficiency but also drives the rotation of the cam by the rotation of the movable copper pipe to squeeze the top wheel and push the gas towards the movable copper pipe to achieve the combined heat dissipation of cold air and water flow, further enhancing the cooling effect. The design of the pressure nozzle and evaporation pipe in the pressure pipe enables the coolant to obtain additional pressure enhancement and evaporation cooling effect when passing through the cylinder, improving the heat absorption capacity of the coolant. The partition in the transition box divides the system into a liquid cavity and an input cavity to avoid energy loss caused by the mixing of hot and cold fluids. Multiple inlet pipes and outlet pipes are evenly distributed to ensure that the cooling medium completely covers the surface of the battery.

[0023] 2. By setting the exhaust holes and the baffle plate driven by the cylinder, the system can easily switch between air cooling and water cooling modes according to different cooling requirements. When air cooling is required, the cylinder contracts, the baffle plate moves away from the exhaust holes, and air is allowed to pass through; when water cooling is required, the cylinder extends, the baffle plate blocks the exhaust holes, and the coolant is ensured to circulate in the liquid cavity. The fan blades are located near the outlet pipe. When the gas is ejected from the outlet pipe, it will drive the fan blades to rotate, and then drive the intake pipe to rotate. This design not only increases the gas flow rate but also enables the suction blades in the intake pipe to more effectively suck gas from the outside. The fins on the outer surface of the intake pipe increase the contact area with the coolant and improve the cooling effect. When the gas passes through the intake pipe, it will pass through the coolant in the liquid cavity and be preliminarily cooled. In addition, the exhaust blades in the exhaust pipe further enhance the gas flow and help to discharge the cooled gas from the system. The driving gear at the top of the intake pipe meshes with the driven gear on the outer surface of the exhaust pipe to form a closed loop for gas circulation. This design not only ensures the continuous flow of gas but also enables the coolant to be fully utilized in the liquid cavity, improving the cooling efficiency. When the system is in the air cooling mode, the gas ejected from the outlet pipe drives the fan blades to rotate, and then drives the intake pipe and the suction blades inside it to rotate. This not only increases the gas flow rate but also enables the gas to be fully in contact with the coolant when passing through the intake pipe and be preliminarily cooled. Subsequently, the cooled gas enters the heat dissipation areas such as the cylinder through the input cavity to further reduce the temperature of the battery. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 3 , the present invention provides a technical solution: a mine underground explosion-proof charger, including a housing 100 and a storage battery 105 arranged inside it, as well as a plug 102 adaptively connected to the storage battery 105. A box door 103 is arranged on one side of the housing 100 away from the transition box 200. One end of the housing 100 is fixedly connected with a rotating rod 104 for driving the box door 103 to rotate. A junction box 101 is fixedly connected to the top of the housing 100. Among them, an isolating switch is arranged inside the box door 103. The power supply switch can be omitted in the early stage, saving equipment investment. At the same time, the junction box 101 can support the plug 102 to provide stability for it.

[0038] Further, please refer to Figure 3 , Figure 4 and Figure 5, further comprising a transition box 200, which is fixedly connected to one side of the housing 100, and a partition is arranged along its center inside the transition box 200, dividing it into a liquid chamber 201 and an input chamber 202. A plurality of inlet pipes 203 are communicated inside the input chamber 202, and a plurality of outlet pipes 205 are communicated inside the liquid chamber 201. A centrifugal pump 204 is commonly connected between the plurality of inlet pipes 203 and the plurality of outlet pipes 205. A plurality of cylinders 206 are arranged inside the outlet pipe 205, and a cooling assembly for locally cooling the storage battery 105 is arranged inside the plurality of cylinders 206. By arranging the centrifugal pump 204, the staggered use of air cooling and water cooling can be realized, so that the storage battery 105 starts air cooling for heat dissipation when slightly heated, and the partition between the input chamber 202 and the liquid chamber 201 can separate the heat carried by the cooling assembly and prevent their mixing from affecting the fluid used for cooling.

[0039] Please refer to Figure 5 , Figure 6 and Figure 7 , the cooling assembly includes a movable copper pipe 208 slidably connected inside the cylinder 206. One side of the movable copper pipe 208 is rotatably connected to a positioning copper sheet 211, and one side of the positioning copper sheet 211 is rotatably connected to a hinged copper handle 212. A plurality of positioning frames 209 are fixedly connected to one side of the storage battery 105, and a copper plate 210 rotatably connected to the hinged copper handle 212 is slidably connected to one side of the positioning frame 209. The movable copper pipe 208, the positioning copper sheet 211, the hinged copper handle 212 and the copper plate 210 are all made of copper, which has strong conductivity and can transfer the heat generated by the storage battery 105 to the inside of the cylinder 206 for heat dissipation. At the same time, the use of the movable copper pipe 208 can prevent external air from mixing into the inside of the housing 100 when there is wind, and improve the service life of the storage battery 105.

[0040] Furthermore, please refer to Figure 6 , Figure 7 and Figure 8, further including a water chamber 300, which is configured to have a plurality of sides uniformly attached to one side of the storage battery 105, and water is stored inside each of them. One side of the water chamber 300 is provided with an efficiency-enhancing component for increasing the efficiency of the cooling component. The efficiency-enhancing component includes a cylinder 301 fixedly connected to and communicating with one side of the water chamber 300. A piston push rod 302 adapted to it is slidably connected to one side of the cylinder 301, and one end of the piston push rod 302 away from its piston end is fixedly connected to the positioning copper sheet 211. One side of the cylinder 206 is fixedly connected to an auxiliary cylinder 207 communicating with it. Copper blades 303 are fixedly connected to the outer surface of the movable copper tube 208. A plurality of water chambers 300 all cover one side of the storage battery 105, and the water inside them monitors the heat generation situation of each part of the storage battery 105 in real time. When the temperature is too high, the water in the water chamber 300 will expand and push the piston push rod 302 to move, so that more areas of the copper plates 210 are placed inside the positioning frame 209, increasing the efficiency of heat conduction. At the same time, the movement of the positioning copper sheet 211 will push the copper blades 303 into the inside of the cylinder 206. At this time, the heat conduction ability of the movable copper tube 208 will be further increased, thereby increasing the cooling effect and realizing efficiency enhancement.

[0041] Among them, both sides of the auxiliary cylinder 207 are communicated with a pressure pipe 305, and a support cylinder 304 is fixedly connected to the inside of the pressure pipe 305. A slide rod 309 is slidably connected to the inside of the pressure pipe 305, and one end of the slide rod 309 is fixedly connected to a piston piece 310 adapted to the pressure pipe 305. A pressure nozzle 307 is fixedly connected to the inside of the pressure pipe 305. An evaporation pipe 306 is fixedly connected to the inside of the pressure pipe 305. One end of the movable copper tube 208 away from the positioning copper sheet 211 is fixedly connected to a cam 308. One end of the slide rod 309 away from the piston piece 310 is rotatably connected to a top wheel 312 that abuts against the cam 308. A return spring 311 for driving its own reset is sleeved on the outer surface of the slide rod 309. Whether it is wind power or water cooling, the fluid will abut against the plurality of copper blades 303 when passing through the inside of the cylinder 206. At this time, the copper blades 303 will be forced to rotate and drive the cam 308 to rotate. The rotation of the cam 308 will compress the fluid inside the pressure pipe 305 to move and spray out through the pressure nozzle 307 into the inside of the auxiliary cylinder 207, thereby assisting in cooling the movable copper tube 208.

[0042] It is worth mentioning that when applied to water cooling, the storage battery 105 at the high-temperature part will push the copper blades 303 to move into the inside of the cylinder 206 and be uniformly mixed with the coolant, thereby improving the heat absorption of the coolant. While the storage battery 105 not at the high-temperature part will cause the copper blades 303 to be placed inside the auxiliary cylinder 207 and unable to fully contact the coolant, thereby reducing the usage rate of the coolant and providing a saving condition for subsequent use.

[0043] Specifically, during the charging process of the storage battery 105, a chemical reaction will occur, generating a certain amount of heat. This heat will dissipate from the surface of the storage battery 105. At this time, the cooling liquid is placed inside the liquid cavity 201. The centrifugal pump 204 is turned on to suck air from multiple inlet pipes 203, so that the gas quickly passes through the outlet pipe 205 and flows through the inside of the cylinder 206 to dissipate heat from the movable copper pipe 208. The movable copper pipe 208 is connected to the copper plate 210 through the positioning copper piece 211 and the hinged copper handle 212, so that the copper plate 210 fits on the surface of the storage battery 105 to absorb heat and dissipate heat. As the local temperature of the storage battery 105 gradually increases, the water vapor in the water cavity 300 in contact with it will evaporate and expand, pushing the piston push rod 302 to move, so that the positioning copper piece 211 moves, thereby pushing the copper blade 303 into the inside of the cylinder 206. At the same time, the copper plate 210 moves downward to increase the area inside the positioning frame 209, increasing its heat dissipation area, and the cooling liquid in the liquid cavity 201 enters the inside of the input cavity 202, and then passes through the inlet pipe 203 and through the outlet pipe 205 to achieve water-cooled heat dissipation. The cooling liquid will contact the copper blade 303 to achieve large-area heat conduction and dissipate heat, thereby suppressing the local temperature of the storage battery 105. The cooling liquid will be re-transported to the inside of the liquid cavity 201 through the outlet pipe 205. When the fluid passes through the copper blade 303 located inside the cylinder 206, it will push the movable copper pipe 208 to rotate, so that the movable copper pipe 208 drives the cam 308 to continuously squeeze the top wheel 312, thereby pushing the piston piece 310 to move and then pushing the gas to blow towards the movable copper pipe 208, so that the cold air cooperates with the water flow to increase the heat dissipation effect.

[0044] In summary, by setting the centrifugal pump 204 to drive the alternating use of air cooling and water cooling, the system can flexibly adjust the cooling method according to the heat generation of the battery 105. Air cooling is started during slight heat generation to save water resources; water cooling is started when the temperature is relatively high to ensure the cooling effect. The movable copper pipe 208, positioning copper sheet 211, hinged copper handle 212, and copper plate 210 in the cooling assembly are all made of copper and have excellent thermal conductivity, which can quickly transfer the heat generated by the battery 105 to the coolant or air for heat dissipation. Multiple water cavities 300 are evenly attached to one side of the battery 105 to monitor the heat generation situation at each location in real time. When the local temperature is too high, the evaporation of water vapor in the corresponding water cavity 300 pushes the piston push rod 302 to move, increasing the area of the copper plate 210 in contact with this area, achieving precise heat dissipation, and avoiding damage to the battery 105 caused by local overheating. The design of the movable copper pipe 208 prevents external air from mixing into the inside of the housing 100 during wind cooling, reduces the intrusion of dust and moisture, and improves the service life of the battery 105. The efficiency enhancement component uses the evaporation of water vapor in the water cavity 300 to push the piston push rod 302 to move, which not only increases the heat conduction efficiency but also drives the rotation of the movable copper pipe 208 to drive the cam 308 to squeeze the top wheel 312, pushing the gas towards the movable copper pipe 208 to achieve combined heat dissipation of cold air and water flow, further enhancing the heat dissipation effect. The design of the pressure nozzle 307 and evaporation pipe 306 in the pressure pipe 305 enables the coolant to obtain additional pressure enhancement and evaporation cooling effects when passing through the cylinder 206, improving the heat absorption capacity of the coolant. The partition in the transition box 200 divides the system into a liquid cavity 201 and an input cavity 202 to avoid energy loss caused by the mixing of hot and cold fluids. Multiple inlet pipes 203 and outlet pipes 205 are evenly distributed to ensure that the cooling medium completely covers the surface of the battery 105.

[0045] Embodiment 2: Please refer to Figure 9 , Figure 10 and Figure 11 , the present invention also provides a technical solution, which is different from the technical solution of Embodiment 1: A mine underground explosion-proof charger, a plurality of discharge holes 400 are opened inside the partition board, and a plurality of blocking plates 401 for blocking the discharge holes 400 are slidably connected to one side of the transition box 200. A cylinder 402 is connected to the plurality of blocking plates 401 together, and the output end of the cylinder 402 is fixedly connected to the transition box 200. By setting the cooperation of the discharge holes 400 and the blocking plates 401, the back-and-forth switching between water cooling and air cooling can be realized, so as to perform heat dissipation according to different heat dissipation requirements and improve convenience.

[0046] Further, a plurality of intake pipes 403 are rotatably connected to the top of the partition plate, and the plurality of intake pipes 403 communicate with the input chamber 202. A plurality of fins 405 are fixedly connected to the outer surface of the intake pipe 403, and a plurality of fan blades 404 are fixedly connected to the outer surface of the intake pipe 403, and the fan blades 404 are close to the outlet pipe 205. By providing the intake pipe 403, external air can smoothly enter the interior of the input chamber 202 through it. At the same time, when air cooling is carried out, the coolant will be located inside the liquid chamber 201. When the air passes through the intake pipe 403, it will pass through the coolant in the liquid chamber 201. At this time, the coolant will initially cool the air. The fins 405 can improve the cooling effect and increase the subsequent air cooling effect. At the same time, the intake pipe 403 can also be used as a coolant replenishment hole to keep the coolant sufficient.

[0047] Among them, a plurality of exhaust pipes 406 are communicated with the top of the liquid chamber 201. A plurality of exhaust blades 408 are fixedly connected to the interior of the plurality of exhaust pipes 406. A driven gear 407 is fixedly connected to the outer surface of the exhaust pipe 406. The top of the intake pipe 403 extends to one side of the exhaust pipe 406 and is fixedly connected with a driving gear 410 meshing with the driven gear 407. A plurality of intake blades 409 are fixedly connected to the interior of the plurality of intake pipes 403. By providing the fan blades 404, the cooperation between the fan blades 404 and the outlet pipe 205 can drive the intake pipe 403 to rotate, so that the fins 405 are fully in contact with the coolant. The cooperation between the intake blades 409 and the exhaust blades 408 can improve the gas flow rate, thereby improving the wind effect. When the coolant is discharged through the outlet pipe 205, it will not be able to drive the fan blades 404 to rotate.

[0048] Specifically, after the gas is ejected from the outlet pipe 205, it blows towards the fan blades 404 to drive the intake pipe 403 to rotate, so that the intake blades 409 rotate to suck gas from the outside through the intake pipe 403 into the interior of the input chamber 202, so that the gas is in contact with the coolant in the liquid chamber 201 when passing through the intake pipe 403 and is cooled, increasing the heat dissipation effect of air cooling.

[0049] In summary, by setting the row of holes 400 and the baffle 401 driven by the cylinder 402, the system can easily switch between the air-cooling and water-cooling modes according to different heat dissipation requirements. When air-cooling is needed, the cylinder 402 contracts, the baffle 401 moves away from the row of holes 400, allowing air to pass through; when water-cooling is needed, the cylinder 402 extends, the baffle 401 blocks the row of holes 400, ensuring that the coolant circulates within the liquid cavity 201. The fan blade 404 is located near the outlet pipe 205. When gas is ejected from the outlet pipe 205, it drives the fan blade 404 to rotate, which in turn drives the intake pipe 403 to rotate. This design not only increases the flow rate of the gas but also enables the suction blades 409 within the intake pipe 403 to more effectively draw in gas from the outside. The fins 405 on the outer surface of the intake pipe 403 increase the contact area with the coolant, improving the cooling effect. When the gas passes through the intake pipe 403, it passes through the coolant within the liquid cavity 201 and is preliminarily cooled. In addition, the exhaust blades 408 within the exhaust pipe 406 further enhance the gas flow, helping to discharge the cooled gas from the system. The driving gear 410 at the top of the intake pipe 403 meshes with the driven gear 407 on the outer surface of the exhaust pipe 406, forming a closed loop for gas circulation. This design not only ensures the continuous flow of gas but also enables the coolant within the liquid cavity 201 to be fully utilized, improving the heat dissipation efficiency. When the system is in the air-cooling mode, the gas ejected from the outlet pipe 205 drives the fan blade 404 to rotate, which in turn drives the intake pipe 403 and the suction blades 409 inside it to rotate. This not only increases the flow rate of the gas but also enables the gas to come into full contact with the coolant when passing through the intake pipe 403 and be preliminarily cooled. Subsequently, the cooled gas enters the heat dissipation areas such as the cylinder 206 through the input cavity 202, further reducing the temperature of the storage battery 105.

[0050] Embodiment 3: Please refer to Figures 1 to 11 , the present invention also provides a technical solution, which is different from the technical solution of Embodiment 1 in that: a method for using a mine underground explosion-proof battery charger includes the following steps:

[0051] S1. During use, it can be connected to the plug 102 for charging;

[0052] S2. During charging, the storage battery 105 will undergo a chemical reaction during the charging process, generating a certain amount of heat. This heat will dissipate from the surface of the storage battery 105. At this time, the cooling liquid is placed inside the liquid cavity 201. The centrifugal pump 204 is turned on to suck air from multiple inlet pipes 203, so that the gas quickly passes through the outlet pipe 205 and flows through the inside of the cylinder 206 to dissipate heat from the movable copper pipe 208. The movable copper pipe 208 is connected to the copper plate 210 through the positioning copper piece 211 and the hinged copper handle 212, so that the copper plate 210 fits on the surface of the storage battery 105 to absorb heat and dissipate heat. After the gas is ejected from the outlet pipe 205, it blows on the fan blade 404 to drive the intake pipe 403 to rotate, so that the intake blade 409 rotates to suck gas from the outside through the intake pipe 403 into the inside of the input cavity 202, so that the gas contacts the cooling liquid in the liquid cavity 201 when passing through the intake pipe 403 to be cooled, increasing the heat dissipation effect of air cooling;

[0053] S3. As the local temperature of the storage battery 105 gradually rises, the water vapor in the water cavity 300 in contact with it will evaporate and expand to push the piston push rod 302 to move, so that the positioning copper piece 211 moves to push the copper blade 303 inside the cylinder 206. At the same time, the copper plate 210 moves downward to increase the area inside the positioning frame 209, increasing its heat dissipation area. At the same time, the air cylinder 402 is turned on to push the blocking plate 401 to move to open the discharge hole 400, so that the cooling liquid in the liquid cavity 201 enters the inside of the input cavity 202, and then passes through the inlet pipe 203 and through the outlet pipe 205 to achieve water cooling. The cooling liquid will contact the copper blade 303 to achieve large-area heat conduction to dissipate heat, thereby suppressing the local temperature of the storage battery 105. The cooling liquid will be re-transported to the inside of the liquid cavity 201 through the outlet pipe 205;

[0054] S4. At the same time, when the fluid passes through the copper blade 303 inside the cylinder 206, it will push the movable copper pipe 208 to rotate, so that the movable copper pipe 208 drives the cam 308 to continuously squeeze the top wheel 312, thereby pushing the piston piece 310 to move and then pushing the gas to blow on the movable copper pipe 208, so that the cold air cooperates with the water flow to increase the heat dissipation effect.
