[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention. Example

[0034] like Figure 1 —6 shows: a high-voltage direct current remote supply device for communication, comprising a high-voltage direct current remote device body 1, wherein a power distribution frame 101, a power module 102, a power carrier communication module 103 and a protection module 104 are installed inside the high-voltage direct current remote device body 1, and both sides of the high-voltage direct current remote device body 1 are rotatably connected to an upper support arm 2 via a rotating shaft, and the side surface of the high-voltage direct current remote device body 1 below the upper support arm 2 is rotatably connected to a lower support arm 3 via a rotating shaft, and the other ends of the upper support arm 2 and the lower support arm 3 are rotatably connected to the upper and lower ends of the side surface of a fixing frame 4 respectively, and the fixing frame 4 is composed of an upper cross bar 8, a lower cross bar 9 and a vertical bar 11 welded together. The lower support arm 3 is connected to the rotating shaft of the high-voltage DC remote device body 1 and is provided with a connecting shaft 1 6. The middle end of the upper support arm 2 is provided with a connecting shaft 2 7. The connecting shaft 1 6 and the connecting shaft 2 7 are respectively rotatably connected to the two ends of the oil pressure buffer 5. The parallelogram connecting rod structure composed of the upper support arm 2, the lower support arm 3, the fixing frame 4, and the high-voltage DC remote device body 1 plays an effective buffering role under the support of the oil pressure buffer 5, and is easy to install, which can effectively ensure the stability of the installation of the high-voltage DC remote device body 1. The structures of the upper support arm 2 and the lower support arm 3 are the same in size, and the fixing frame 4 is parallel to the back plate of the high-voltage DC remote device body 1. The upper support arm 2, the lower support arm 3, the fixing frame 4, and the high-voltage DC remote device body 1 can form a parallelogram connecting rod, so as to stably support the high-voltage DC remote device body 1. The connecting shaft 1 6 and the connecting shaft 2 7 are the same size and are both composed of an optical axis 61 and a screw 62. The two ends of the oil pressure buffer 5 are rotatably sleeved on the outside of the optical axis 61. The oil pressure buffer 5 can rotate smoothly under the support of the optical axis 61. The screw 62 is threaded with a nut. Under the limit locking of the nut, the oil pressure buffer 5 can be stably installed on the optical axis 61. The upper cross bar 8 and the lower cross bar 9 have the same structure and are arranged relatively up and down. The number of the vertical rods 11 is multiple The upper and lower ends of the vertical rod 11 are welded to the end faces of the upper cross bar 8 and the lower cross bar 9. The frame structure composed of the upper cross bar 8, the lower cross bar 9 and the vertical rod 11 is stable, which can ensure the stability of the installation of the high-voltage DC remote device body 1. The upper cross bar 8 and the lower cross bar 9 are both angle iron structures. The left and right ends of the upper cross bar 8 and the lower cross bar 9 are welded with square plate structures. The upper support arm 2 and the lower support arm 3 can be stably connected to the square plates welded at both ends of the upper cross bar 8 and the lower cross bar 9. The upper cross bar 8 and the lower cross bar 9 are both provided with installation grooves 10. The installation grooves 10 are strip groove structures. The installation grooves 10 provide sufficient installation margins for the expansion bolts on the installation surface.

[0035] The working principle of this technical solution is as follows: when the device is not installed, the fixing frame 4 is resting on the back plate of the high-voltage DC remote device body 1 under the action of gravity and the support of the upper support arm 2 and the lower support arm 3. When the high-voltage DC remote device body 1 needs to be installed, the two ends of the separately stored oil pressure buffer 5 are sleeved on the connecting shaft 1 6 and the connecting shaft 2 7, and the nut is screwed on the screw 62 to ensure the stability of the installation of the oil pressure buffer 5. At this time, a parallelogram structure is formed between the upper support arm 2, the lower support arm 3, the fixing frame 4 and the high-voltage DC remote device body 1. The operator installs the expansion bolts on the mounting surface according to the position of the mounting groove 10, and installs the device on the mounting surface through the expansion bolts; when vibration occurs due to the influence of the surrounding environment or the working reasons of the high-voltage DC remote device body 1 itself, the oil pressure buffer 5 expands and contracts to absorb the potential energy generated when the high-voltage DC remote device body 1 is displaced, thereby reducing the impact on the connection strength between the device and the mounting surface;

[0036] When the device is working, high-voltage direct current enters the remote device module through the transmission cable, and is first distributed and connected by the distribution frame 101. The distribution frame 101 distributes the high-voltage direct current to the power module 102, and the power module 102 converts it into the required low-voltage power and outputs it to the remote device for use. The power carrier communication module 103 realizes data communication between the remote device and the local device, including functions such as status monitoring and remote control. At the same time, the monitoring software also obtains the operating status information of the remote device through the power carrier communication module, and performs real-time analysis and processing. The protection module 104 monitors the operating status of the equipment in real time, and cuts off the power supply or issues an alarm signal in time when an abnormal situation occurs to ensure the safe operation of the equipment, thereby achieving stable operation and efficient power supply of the equipment.
