Description

Technical Field

[0001] This utility model relates to the technical field of voltage regulation devices, specifically to a voltage regulation device for a DC power supply. Background Technology

[0002] A DC power supply unit is a key device that provides stable DC power to a power system. It is mainly used in substations, power plants, industrial power distribution systems, and communication base stations. It is responsible for providing reliable power to critical loads such as relay protection devices, control systems, emergency lighting, and communication equipment. In power systems, loads such as relay protection devices, circuit breaker opening and closing, and communication equipment may experience instantaneous start-up and shutdown, leading to sudden current changes. If the voltage is not regulated, it may cause a sudden voltage drop or rise, affecting the normal operation of the equipment. By regulating the output voltage, the DC bus voltage is kept stable, avoiding control signal distortion or equipment malfunction caused by sudden load changes.

[0003] Voltage regulators need to be connected to a power source during use, but the power supply interface is often exposed to the outside, which can lead to the entry of impurities that adhere to the terminals. This can affect the normal connection of the power supply and cause the device to become unstable. Therefore, in order to avoid the above problems, a new voltage regulator for DC power supplies is needed. Utility Model Content

[0004] The purpose of this invention is to provide a voltage regulating device for DC power supplies to solve the problem in the background art where impurities at the wiring ports affect the device connection.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A voltage regulating device for a DC power supply includes a voltage regulating power supply device body for regulating the voltage of the DC power supply. A power interface is fixedly installed on the top of the voltage regulating power supply device body. A protection mechanism for protecting the power interface is plugged into the outside of the power interface. The protection mechanism is connected to the voltage regulating power supply device body. A working module is electrically connected to one side of the voltage regulating power supply device body for controlling the voltage regulating power supply device body to regulate the voltage of the DC power supply.

[0007] The protection mechanism includes a mounting plate, on the bottom of which a plug-in block is fixedly mounted. The plug-in block is plugged into the power interface. The bottom of the plug-in block has a mounting groove that is plugged into the power interface. Cleaning plates are symmetrically arranged in the mounting grooves at the bottom of the plug-in block.

[0008] Using the above technical solution, during the use of the device, debris may adhere to the surface of the power interface connection terminals, which will affect the stability of the connection. Therefore, the device is equipped with a protective mechanism to protect the power interface. After each use, the protective mechanism can be inserted into the power interface. After removing the debris from the surface of the power interface connection terminals, the mounting plate and the plug block can be inserted into the power interface to completely seal the power interface, preventing the power interface from contacting the external environment and preventing the adhesion of debris. In addition, the cleaning plate inside the plug block can rub the surface of the power interface connection terminals to maintain the connection between the terminals and the power interface.

[0009] A further improvement of this utility model is that: a number of cleaning blocks are fixedly installed at equal intervals on one side of the cleaning plate, and connecting blocks are fixedly installed symmetrically on both sides of the cleaning plate. An installation rod is installed on the connecting block, and the installation rod is rotatably connected to the end of the elastic plate.

[0010] By adopting the above technical solution, the cleaning blocks installed on the surface of the cleaning plate can further improve the friction of the protection mechanism on the power interface terminals, and can rub the surface of the terminals to further improve the cleanliness of the terminal surface and increase the electrical connection fit of the device. In addition, the cleaning blocks are arranged in a trapezoidal shape, which can accommodate the impurities cleaned when cleaning the surface of the terminals, and prevent the impurities of the cleaning blocks from adhering to the surface of the cleaning blocks and affecting the cleaning effect. The elastic plate can keep the two cleaning plates in contact with the surface of the connecting terminals at all times, increasing the cleanliness of the connecting terminal surface by the two cleaning plates.

[0011] A further improvement of this utility model is that: a rotating seat is rotatably connected to the top of the mounting plate, and a fixed seat is installed on the upper surface of the voltage regulating power supply device body; the rotating seat and the fixed seat are connected to each other by a connecting rope.

[0012] By adopting the above technical solution, the setting of the connecting rope ensures that the protection mechanism is always connected to the voltage regulating power supply device body during use, preventing the device from falling off and the protection mechanism from being lost. The setting of the rotating seat and the fixed seat increases the connection and fit between the connecting rope, the mounting plate and the voltage regulating power supply device body, further increasing the stability of the device during use.

[0013] A further improvement of this utility model is that a 15° inclined surface is provided on one side of the cleaning plate.

[0014] By adopting the above technical solution, the 15° slope on one side of the cleaning plate can further increase the compatibility between the protection mechanism and the power interface during the insertion process, thereby increasing the stability of the device and making it easier to separate the two cleaning plates during the insertion process, so that the cleaning plate can clean the connection terminals of the power interface.

[0015] A further improvement of the present invention is that: a snap-fit ​​plate is rotatably connected to one side of the mounting plate, and one end of the snap-fit ​​plate is snap-fitted to one side of the power interface; a pressing block is symmetrically fixedly installed at the bottom of the rotating seat; and a mating seat that presses against the pressing block is fixedly installed at the end of the snap-fit ​​plate near the rotating seat.

[0016] By adopting the above technical solution, the snap-fit ​​plate can increase the connection stability between the protection mechanism and the power interface, and prevent the protection mechanism from falling off. In addition, in order to further increase the stability of the snap-fit ​​plate during use, a pressing block is provided at the bottom of the rotating seat. The pressing block, together with the mating seat, can restrict the snap-fit ​​plate and prevent accidental collisions from causing the snap-fit ​​plate to rotate, thereby causing the snap-fit ​​plate to release the restriction between the power interface and the protection mechanism and fall off.

[0017] A further improvement of this utility model is that: four locking blocks are fixedly installed in a ring on the upper surface of the mounting plate, and the bottom end of the rotating seat is provided with mating grooves that engage with the locking blocks at equal intervals.

[0018] By adopting the above technical solution, the setting of the locking block and the mating groove can increase the stability of the extrusion block during the extrusion mating process, and further enable the locking plate to restrict the protection mechanism and the main body of the voltage regulating power supply device, thereby further improving the stability of the device in use.

[0019] A further improvement of this utility model is that handles are symmetrically fixedly installed on the upper surface of the voltage regulating power supply device body.

[0020] By adopting the above technical solution, the addition of a handle can increase the convenience of the device during transportation and make it easier for staff to use.

[0021] A further improvement of this utility model is that a lightweight groove is provided on one side of the snap-fit ​​plate.

[0022] By adopting the above technical solution, the lightweight groove on one side of the snap-fit ​​plate can reduce the overall weight of the protection mechanism.

[0023] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0024] 1. This utility model can connect the power interface of the device by setting a protection mechanism, so as to prevent impurities from entering the internal part of the power interface when it is not in use and adhering to the surface of the terminal block, thereby affecting the stability of the device during the electrical connection process. In addition, the setting of the protection mechanism can remove the adhering substances and oxides on the surface of the terminal block, keep the surface of the terminal block clean, and further improve the smoothness and stability of the device.

[0025] 2. This utility model has a connection structure on the protection mechanism, which can always be connected to the device when the protection mechanism is not in use, so as to avoid loss. In addition, the protection mechanism is also provided with a limiting structure, which can increase the connection between the protection mechanism and the power interface, thereby increasing the protection performance of the protection mechanism.

Therefore, the device is equipped with a protective mechanism 4 to protect the power interface 3. After each use, the protective mechanism 4 can be inserted into the power interface 3. After removing the debris from the surface of the connection terminals of the power interface 3, the mounting plate 6 and the plug block 7 are inserted into the power interface 3 to seal the power interface 3, preventing the power interface 3 from contacting the external environment and preventing the adhesion of debris. In addition, the cleaning plate 8 provided inside the plug block 7 can rub the surface of the connection terminals of the power interface 3 to maintain the connection between the wiring terminals and the power interface 3.

An installation rod 11 is installed on the connecting block 10, and the installation rod 11 is rotatably connected to the end of the elastic plate 12.

[0045] In this embodiment, the cleaning block 9 installed on the surface of the cleaning plate 8 can further increase the friction of the protection mechanism 4 on the power interface 3 terminal block, and can rub the surface of the terminal block (impurities, oxides, etc.), further improving the cleanliness of the terminal block surface and increasing the electrical connection fit of the device. In addition, the cleaning block 9 is trapezoidal, which can accommodate the impurities cleaned when cleaning the surface of the terminal block, and avoid the impurities adhering to the surface of the cleaning block 9 and affecting the cleaning effect of the cleaning block 9. The elastic plate 12 can keep the two cleaning plates 8 in contact with the surface of the connection terminal at all times, increasing the cleanliness of the connection terminal surface by the two cleaning plates 8.

[0046] like Figure 6 As shown, preferably, a rotating seat 14 is rotatably connected to the top of the mounting plate 6, and a fixed seat 15 is installed on the upper surface of the voltage regulating power supply device body 1.

The rotating seat 14 and the fixed seat 15 increase the connection between the connecting rope 16, the mounting plate 6, and the voltage regulating power supply device body 1, further increasing the stability of the device during use.

[0048] like Figure 5 As shown, preferably, one side of the cleaning plate 8 is provided with a 15° slope.

[0049] In this embodiment, the 15° bevel on one side of the cleaning plate 8 can further increase the fit between the protection mechanism 4 and the power interface 3 during the insertion process, thereby increasing the stability of the device and making it easier to separate the two cleaning plates 8 during the insertion process, so that the cleaning plate 8 can clean the connection terminals of the power interface 3.
