Description

Technical Field

[0001] The utility model relates to the technical field of voltage-stabilized power supplies, in particular to a direct current voltage-stabilized power supply for mining. Background Art

[0002] The mining DC regulated power supply is a power supply device specially designed for mining environment. Its main function is to provide stable and reliable DC voltage output for mining equipment under unstable or fluctuating input voltage conditions.

[0003] In the prior art, in order to ensure the safety of the mine, equipment such as DC regulated power supplies for mines are designed to be explosion-proof. At present, the explosion-proof type of DC regulated power supplies used in mines is both flameproof and intrinsically safe. Among them, the flameproof type is to contain the possible explosion inside through a solid shell to ensure that the explosion will not spread to the external environment, thereby protecting the people and equipment around. The intrinsically safe type is to limit the energy in the circuit to ensure that even under the most unfavorable fault conditions, the sparks or thermal effects generated in the circuit will not ignite explosive gases or dust. The flameproof and intrinsically safe type means that the equipment has both a solid flameproof shell and an intrinsically safe circuit design.

[0004] Therefore, in order to ensure safe operation in potentially explosive gas or dust environments, the shell of the explosion-proof and intrinsically safe DC regulated power supply for mining usually needs to be designed to be very strong and sealed to withstand the pressure of the internal explosion without breaking, while preventing sparks or thermal effects from being transmitted to the external environment. This design leads to a large weight and volume of the shell, which occupies a large area, making transportation and installation inconvenient, especially in the space-limited underground mine environment. This increase in volume and weight makes the placement and layout of the equipment a major challenge. In addition, the layout of the circuit boards inside the mining DC regulated power supply also directly affects the overall volume and efficiency of the equipment. The traditional layout method may not fully consider the space utilization, resulting in the need for a larger space inside the shell to accommodate all the necessary components, further increasing the footprint of the equipment. This not only affects the portability and installation flexibility of the equipment, but may also make it difficult to find a suitable location for deployment in the small space under the mine.

The third circuit component 4 is connected to the second circuit component 3 through the plurality of second support members 200, so that the third circuit component 4 is spaced above the second circuit component 3.

[0034] Preferably, there are four second support members 200 , and the four second support members 200 are located at four corners of the third circuit component 4 .

[0035] Specifically, Figure 2 and Figure 4 As shown, the DC regulated power supply for mining further includes: an energy storage component 5, which is arranged in a sealed space, located at one side of the first circuit component 2, and electrically connected to the second circuit component 3 and the first circuit component 2 respectively; wherein the second circuit component 3 is also used to control the energy storage part 50 of the energy storage component 5 to charge and discharge and monitor the charge and discharge state of the energy storage part 50 of the energy storage component 5; when the energy storage part 50 is in a discharge state, the output power of the energy storage part 50 is transmitted to the first circuit component 2. With such a structural arrangement, the energy storage component 5 is arranged so that when there is no external power supply, the energy storage component 5 can be used to provide power to the load to ensure normal operation of the load.

[0036] Furthermore, if Figure 2 As shown, the energy storage part 50 of the energy storage component 5 is an energy storage battery pack. The energy storage battery pack includes at least one energy storage battery. The energy storage component 5 also includes: a battery protective cover 51, a mounting plate 52, and a plurality of wire ties 53. The battery protective cover 51 is used to wrap the plurality of energy storage batteries to achieve physical protection. The wrapped energy storage part 50 is mounted on the mounting plate 52. The mounting plate 52 is provided with two positioning grooves. The two positioning grooves are respectively arranged on both sides of the mounting plate 52 and are arranged correspondingly. The plurality of wire ties 53 fix the energy storage part 50 on the mounting plate 52, and when the plurality of wire ties 53 are bundled, the plurality of wire ties 53 are located in the positioning grooves.

[0038] Among them, the second circuit component 3 (i.e., the power control circuit board) can control the on / off operation of the mining DC regulated power supply. When the second circuit component 3 (i.e., the power control circuit board) performs the power-on action, it will start the entire power supply system. If there is an external power supply, the external power supply will transmit electricity to the first circuit component 2 (i.e., the power conversion circuit board), and the first circuit component 2 (i.e., the power conversion circuit board) will perform power conversion, convert the AC power of the external power supply into a lower voltage DC power, and then transmit it to the second circuit component 3 (i.e., the power control circuit board), and the second circuit component 3 (i.e., the power control circuit board) will adjust the voltage of the converted power supply.

If the energy storage unit 50 needs to be charged, the converted power supply will be shunted, one part is used to meet the load demand, and the other part is used to charge the energy storage unit 50. During the charging process, the second circuit component 3 (i.e., the power control circuit board) will adjust the voltage of the power supply to ensure that the charging voltage and the output voltage meet the requirements. Then, the power supply with the voltage that meets the load voltage is transmitted to the third circuit component 4 (i.e., the interface circuit board), and is transmitted to the load by the third circuit component 4 (i.e., the interface circuit board). In addition, the second circuit component 3 (i.e., the power control circuit board) transmits data such as the power monitoring status of the energy storage unit 50, the monitoring status of the power conversion of the first circuit component 2 (i.e., the power conversion circuit board), and the power distribution status of the second circuit component 3 (i.e., the power control circuit board) to the third circuit component 4 (i.e., the interface circuit board), and is transmitted to the terminal (i.e., the management terminal) by the third circuit component 4 (i.e., the interface circuit board) to realize remote monitoring and data analysis.

[0039] If there is no external power supply or the power supply capacity of the external power supply cannot meet the load demand, the second circuit component 3 (i.e., the power control circuit board) will control the energy storage unit 50 to discharge, and transmit the power output of the energy storage unit 50 and / or the power output of the external power supply to the first circuit component 2 (i.e., the power conversion circuit board), and the first circuit component 2 (i.e., the power conversion circuit board) will perform power conversion, convert the input power into a lower voltage direct current, and then transmit it to the second circuit component 3 (i.e., the power control circuit board), and the second circuit component 3 (i.e., the power control circuit board) will adjust the voltage of the converted power to meet the load demand. At the same time, it will monitor the power conversion of the first circuit component 2 (i.e., the power conversion circuit board) and the energy storage state of the energy storage unit 50. Then, the power with the voltage that meets the load voltage is transmitted to the third circuit component 4 (i.e., the interface circuit board), and the third circuit component 4 (i.e., the interface circuit board) transmits it to the load. In addition, the second circuit component 3 (i.e., the power control circuit board) will transmit data such as the power monitoring status of the energy storage unit 50 and the monitoring status of the power conversion of the first circuit component 2 (i.e., the power conversion circuit board) to the third circuit component 4 (i.e., the interface circuit board), which will be transmitted to the terminal (i.e., the management terminal) by the third circuit component 4 (i.e., the interface circuit board) to realize remote monitoring and data analysis.

In addition, the fixing component 6 provides a stable support to ensure that the circuit components remain stable when the equipment is running, and reduces circuit failures caused by vibration or movement.

At the same time, the connecting rod 81 of each second locking member 8 passes through the corresponding connecting hole 61 and is locked with the locking portion 82 of the corresponding second locking member 8, thereby fixing the fixing member 6 so that the fixing member 6 is firmly connected to the housing 1. Here, each first locking member 7 passes through at least part of the energy storage member 5 and the fixing member 6 in sequence and is connected to the housing 1, thereby further strengthening the firmness of the connection between the fixing member 6 and the housing 1 through each first locking member 7, and making the locking force evenly distributed, ensuring that the fixing member 6 can be stably installed inside the mining DC regulated power supply, and avoiding displacement of the fixing member 6 due to vibration or movement of the equipment.

[0045] Specifically, the fixing part 6 is also provided with a plurality of limiting holes, and the plurality of communicating holes 61 are arranged one by one with the plurality of limiting holes, and each communicating hole 61 is connected with the corresponding limiting hole. When the connecting rod 81 of the second locking member 8 passes through the communicating hole 61, the fixing part 6 is moved to clamp the connecting rod 81 of the second locking member 8 in the limiting hole, so as to limit the connecting rod 81 of the second locking member 8 through the limiting hole. With such a structural setting, the cooperation between the limiting hole and the connecting rod 81 ensures the firm fixation of the second locking member 8 on the fixing part 6, improves the structural stability and mechanical strength of the whole device, and reduces the loosening of the parts caused by vibration or movement.
