Description

Technical Field

[0001] This invention relates to the field of energy storage cable assembly technology, specifically a digital energy storage cable assembly for mining. Background Technology

[0002] Energy storage cable assemblies are key connection units in new energy storage systems. They consist of energy storage cables, connectors, and protection devices. They are mainly used for energy transfer between battery modules, batteries, and inverters. Therefore, they can be used as emergency power supplies for mines. When the power supply to the coal mine is interrupted, the energy storage cable assemblies can use electrochemical energy storage and high-voltage cascade frequency conversion technology to achieve uninterrupted and seamless switching, ensuring the normal operation of emergency load motor equipment and ensuring the safe operation of the system.

[0003] However, existing digital energy storage cable assemblies for mining require frequent charging and discharging of their internal battery packs during operation, generating significant heat. When the cable assemblies are placed underground, the heat dissipation relies solely on mine ventilation. Since the location of the heat dissipation vents at the top of the cable assemblies is usually fixed, the airflow direction inside the mine is opposite to the direction of the heat dissipation vents, hindering the proper heat dissipation of the energy storage cable assemblies. Furthermore, the battery packs inside existing energy storage cable assemblies are typically placed in fixed locations within the cable assemblies. When a single battery needs maintenance or replacement, the entire battery pack must be removed for testing, making the battery maintenance and replacement process cumbersome and time-consuming. Summary of the Invention

[0004] The purpose of this invention is to provide a digital energy storage cable assembly for mining to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mining digital energy storage cable assembly, comprising an outer shell, a connecting pipe extending through the top of the outer shell, a top plate covering the top of the connecting pipe, a cavity inside the top plate, sliding boxes on all four sides of the cavity, a vertical plate fixedly connected to the side of the sliding box facing the outside of the top plate, a heat dissipation vent at the bottom of the sliding box, an opening on the side of the sliding box facing the cavity, side ear plates fixedly connected to both side walls of the sliding box, a limiting rod movably passing through the middle of the side ear plate, and a telescopic spring sleeved on the outside of the limiting rod;

[0006] Two cable conduits are installed on the top of one side wall of the outer casing. A door panel is installed on the front of the outer casing, and a control panel is installed on the front of the door panel. Multiple drawer panels are installed inside the outer casing, and multiple through holes are opened at the top of the drawer panels. Insert rods are movably inserted into the inner side of some of the through holes. Suction cups are installed at the top of the insert rods, and energy storage batteries are attached to the top of the suction cups. A base is installed at the bottom of the outer casing, and two fans are installed on one side wall of the base.

[0007] Preferably, a sliding cavity is provided at the junction of the top plate and the two side walls of the sliding box, and the two ends of the limiting rod are fixed to the two side walls of the sliding cavity.

[0008] Preferably, one end of the telescopic spring is fixedly connected to one side wall of the side ear plate, and the other end of the telescopic spring is fixedly connected to one side inner wall of the sliding cavity. The side ear plate is slidably connected to the sliding cavity through the telescopic spring.

[0009] Preferably, the inner wall of the outer casing is provided with multiple sets of slide rails, and the drawer is slidably connected to the outer casing through the slide rails.

[0010] Preferably, the heat dissipation vent communicates with the interior of the cavity through an opening, and the cavity communicates with the interior of the outer casing through a connecting pipe.

[0011] Preferably, the air outlet of the fan is connected to the interior of the outer casing, and the air inlet of the fan is connected to the outside.

[0012] Preferably, the energy storage battery is connected to the pull plate via a suction cup and a plug.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This mine-use digital energy storage cable assembly, through the top plate, sliding box, side ear plate, limit rod and telescopic spring, has heat dissipation vents in four directions: front, back and left, right. The size of each heat dissipation vent can be flexibly adjusted in real time according to the direction of ventilation airflow in the mine. At the same time, the heat dissipation vents face downwards, which is not easily disturbed by the ventilation airflow in the mine, so that the heat inside the energy storage cable assembly can be dissipated smoothly, thus helping to ensure the normal heat dissipation of the energy storage cable assembly.

[0015] 2. This mine-use digital energy storage cable assembly uses a pull plate, suction cups, insertion rods, and through holes to allow the battery packs within the energy storage cable assembly to be placed in layers, with each layer containing a single battery. The bottom of each battery layer is attracted by the suction cups, allowing the insertion rods at the bottom of the suction cups to connect with the bottom of the batteries. The insertion rods are then inserted into the through holes on the pull plate, keeping the batteries relatively stationary. The batteries are then pulled out as the pull plate is moved, facilitating the inspection or replacement of individual batteries within the energy storage cable assembly. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 4As shown, a mining digital energy storage cable assembly includes an outer shell 4 made of mining explosion-proof material to reduce the impact of mine explosions on the internal battery. A connecting pipe 19 passes through the top of the outer shell 4, connecting the interior of a top plate 1 to the interior of the outer shell 4. This allows heat from the outer shell 4 to be blown into the top plate 1 by a fan 9, thus achieving normal heat dissipation for the energy storage cable assembly. A top plate 1, the same size as the top surface of the outer shell 4, covers the top of the connecting pipe 19, protecting the top of the outer shell 4 from impacts caused by falling coal slag. A connecting rod is fixed to the bottom of the top plate 1, securing it to the outer shell 4. A cavity 20, with a cross-shaped cross section, is formed inside the top plate 1, allowing heat from the connecting pipe 19 to escape from the top plate 1 in four directions (front, back, left, and right), improving the heat dissipation of the energy storage cable assembly. Each of the four sides of the cavity 20 is equipped with a sliding box 2. The sliding box 2 can slide inward or outward along the inner wall of the cavity 20, thereby changing the size of the heat dissipation vent 13 at the bottom of the sliding box 2. A vertical plate 3 is fixedly connected to the side of the sliding box 2 facing the outside of the top plate 1. The function of the vertical plate 3 is to limit the outward side of the sliding box 2 and prevent the sliding box 2 from being blown into the top plate 1 by the airflow in the mine. A heat dissipation vent 13 is opened at the bottom of the sliding box 2. A dustproof net is installed at the bottom of the heat dissipation vent 13 to prevent coal ash from entering the top plate 1 through the heat dissipation vent 13. Inside the outer shell 4, the sliding box 2 has an opening 18 on the side facing the cavity 20. The opening 18 connects the interior of the sliding box 2 with the cavity 20 in the top plate 1. Side ear plates 15 are fixedly connected to both sides of the sliding box 2. The side ear plates 15 help the sliding box 2 maintain better stability when sliding in the cavity 20. A limit rod 14 moves through the middle of the side ear plate 15. A telescopic spring 16 is sleeved on the outside of the limit rod 14. The telescopic spring 16 can push the sliding box 2 to slide through its own deformation.

[0023] Two cable conduits 5 are installed on the top of one side wall of the outer casing 4. The cable conduits 5 are used to electrically connect external cables to this energy storage cable group, enabling the energy storage cable group to input or output current normally. A door panel 7 is installed on the front of the outer casing 4, and a control panel 6 is installed on the front of the door panel 7. The control panel 6 has a human-machine interface, which can monitor the temperature, voltage, and power of the battery inside the outer casing 4 in real time, and can accurately display the running time and remaining running time of this energy storage cable group. Multiple drawer plates 11 are installed inside the outer casing 4. The drawer plates 11 are arranged parallel to each other inside the outer casing 4, so that the drawer plates 11 can be pulled out horizontally along the inside of the outer casing 4. Multiple through holes are opened at the top of the drawer plates 11. 23. A rod 22 is inserted into the inner side of a portion of the through hole 23. The outer diameter of the rod 22 is matched with the inner diameter of the through hole 23, so that the rod 22 can be inserted tightly into the plate. A suction cup 21 is provided at the top of the rod 22. The function of the suction cup 21 is to connect the rod 22 to the bottom of the battery. A storage battery 12 is attached to the top of the suction cup 21. There is one storage battery 12 on each layer of the drawer plate 11, and the batteries in each layer are connected in series. A base 8 is provided at the bottom of the outer shell 4. Two fans 9 are installed on one side wall of the base 8. The fans 9 can blow airflow from bottom to top into the outer shell 4, thereby facilitating the heat dissipation vent 13 at the top of the top plate 1 to dissipate the heat inside the outer shell 4.

[0024] Specifically, a sliding cavity 17 is provided at the junction of the top plate 1 and the two side walls of the sliding box 2. The two ends of the limiting rod 14 are fixed to the two side walls of the sliding cavity 17. The function of the limiting rod 14 is to limit the side ear plate 15 so that the side ear plate 15 can slide stably in the sliding cavity 17, thereby helping the sliding box 2 to maintain better stability when sliding.

[0025] Furthermore, one end of the telescopic spring 16 is fixedly connected to one side wall of the side ear plate 15, and the other end of the telescopic spring 16 is fixedly connected to one side inner wall of the slide cavity 17. The side ear plate 15 is slidably connected to the slide cavity 17 through the telescopic spring 16. The deformation of the telescopic spring 16 can push the slide box 2 to reset, so that the heat dissipation port 13 at the bottom of the slide box 2 can be flexibly adjusted to reduce the adverse effects of airflow in the mine on the heat dissipation of the energy storage cable group.

[0026] Furthermore, the inner wall of the outer casing 4 is provided with multiple sets of slide rails 10, and the pull plate 11 is slidably connected to the outer casing 4 through the slide rails 10. When the pull plate 11 is pulled outward, it can pull out the battery placed on the pull plate 11, thereby facilitating the inspection and replacement of the battery.

[0027] Furthermore, the heat dissipation vent 13 is connected to the interior of the cavity 20 through the opening 18, and the cavity 20 is connected to the interior of the outer shell 4 through the connecting pipe 19, so that the heat inside the outer shell 4 can enter the cavity 20 of the top plate 1 through the connecting pipe 19, thereby facilitating the heat inside the cavity 20 to be blown out from the heat dissipation vent 13.

[0028] Furthermore, the air outlet of the fan 9 is connected to the interior of the outer casing 4, and the air inlet of the fan 9 is connected to the outside. A dustproof mesh cover is installed at the air inlet of the fan 9, which can reduce the amount of coal ash entering the interior of the outer casing 4. The fan 9 can blow outside air into the interior of the outer casing 4, so that the heat inside the outer casing 4 can be accelerated upward into the top plate 1, thereby helping to speed up the heat dissipation of this energy storage cable group.

[0029] Furthermore, the energy storage battery 12 is connected to the pull plate 11 via the suction cup 21 and the insertion rod 22, so that the energy storage battery 12 can move synchronously with the pull plate 11 when it is pulled out, which makes it easier to remove the energy storage battery 12.

[0030] The usage method of this embodiment is as follows: When using this mine-use digital energy storage cable assembly, first connect the cable assembly to the power supply system of the coal mine. Then, start the energy storage cable assembly. At this time, the fan 9 for air cooling inside the base 8 of the energy storage cable assembly will start, causing air to be blown into the inside of the outer casing 4. Then, the airflow blown into the outer casing 4 will cause the heat generated by the battery inside the outer casing 4 to rise rapidly. Then, the heat will enter the cavity 20 of the top plate 1 through the connecting pipe 19. Then, the heat in the cavity 20 will enter the slide box 2 through the opening 18 on the side of the slide box 2, and then be blown out from the heat dissipation vent 13 at the bottom of the slide box 2. When the outside of the top plate 1 is disturbed by the oncoming wind in the mine, the slide box 2 in the corresponding direction is pushed and slid in by the action of the vertical plate 3. Inside the top plate 1, the heat dissipation vent 13 at the bottom of the sliding box 2 will become smaller. As airflow continues to enter the outer shell 4, the sliding boxes 2 in the other three directions on the outside of the top plate 1 are forced to blow outward, making the heat dissipation vent 13 at the bottom of the other sliding boxes 2 larger. This allows the heat inside the outer shell 4 to be blown out through the other three heat dissipation vents 13, thus ensuring the normal heat dissipation of this energy storage cable group. When it is necessary to remove the battery from the outer shell 4 for maintenance or replacement, simply pull the corresponding battery-located pull plate 11 outward, so that the pull plate 11 slides out along the slide rail 10. Then the battery can be removed from the pull plate 11, so that the suction cup 21 and the insertion rod 22 attached to the bottom of the battery detach from the insertion hole of the pull plate 11. Finally, the battery can be maintained.
