It, together with the power system's relay protection, safety and stability control system, and dispatching automation system, can ensure the safety and stability of the power system. Modules are required for optical transmission of power communication. The modules are set in the shell. During the use of the modules, the heat generated by the modules inside the shell needs to be dissipated.

[0003] The utility model with application number CN202120895627.3 discloses a module heat dissipation device for power communication optical transmission, including a heat dissipation device body, a heat dissipation fan is installed inside the heat dissipation device body, a dustproof plate is installed on the top of the heat dissipation device body, a cleaning assembly is installed inside the dustproof plate, and the cleaning assembly includes an air outlet and a filter plate.

[0004] The above device mainly dissipates the heat generated by the module to the outside through the air outlet and the filter plate when dissipating heat, but its ventilation area is limited. When the module continues to work and the internal temperature of the device is too high, the generated heat cannot be dissipated in a short time, which can easily cause the temperature inside the device to be too high and damage the module. Utility Model Content

[0007] As an improvement of the above technical solution: a moving component is also provided inside the carrier shell, and the moving component is used to drive multiple groups of shielding frames to move closer to or away from the second vent. The moving component includes an electric telescopic rod, and the electric telescopic rod is fixedly installed on the top of the inner wall of the carrier shell, and the output rod of the electric telescopic rod is fixedly connected to the adjacent shielding frame, and the multiple shielding frames are fixedly connected by connecting pillars.

[0008] As an improvement of the above technical solution: it also includes a temperature sensor and a controller installed inside the carrier shell, a fan is installed at the bottom end of the carrier shell, and the fan, the electric telescopic rod and the temperature sensor are all electrically connected to the controller.

[0011] Beneficial effects of the utility model:

[0012] The temperature inside the carrier shell is monitored by a temperature sensor, and a threshold value of the temperature sensor is preset by a controller.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] Example

[0019] Please refer to Figure 1-Figure 3 The optical transmission communication module housing comprises a carrier housing 1 for accommodating the optical transmission communication module, a fan is arranged inside the carrier housing 1, and a plurality of ventilation structures are arranged on the side walls of the carrier housing 1 from top to bottom, and two groups are shown in the figure in the present application, and the ventilation structure comprises a first vent 2 and a second vent 4 which are arranged in the circumference of the carrier housing 1, a filter screen 3 is installed in the first vent 2, and the filter screen 3 is used to prevent the external dust and impurities from entering the carrier housing 1 under normal state, and a plurality of shielding frames 7 are slidably connected to the inner wall of the carrier housing 1, and when one of the shielding frames 7 is moved close to a second vent 4 and shields the second vent 4, the remaining shielding frames 7 shield the remaining second vents 4 one by one.

[0020] In an optional embodiment: a moving component is also provided inside the carrier shell 1, and the moving component is used to drive multiple groups of shielding frames 7 to move closer to or away from the second vent 4. The moving component includes an electric telescopic rod 6, and the electric telescopic rod 6 is fixedly installed on the top of the inner wall of the carrier shell 1. The output rod of the electric telescopic rod 6 is fixedly connected to the approaching shielding frame 7, and the multiple shielding frames 7 are fixedly connected by connecting pillars 71. The electric telescopic rod 6 facilitates the synchronous movement of multiple shielding frames 7 toward the second vent 4 and shielding.

[0021] In an optional embodiment: it also includes a temperature sensor 9 and a controller installed inside the carrier shell 1, a fan 5 is installed at the bottom end of the carrier shell 1, the fan 5, the electric telescopic rod 6 and the temperature sensor 9 are all electrically connected to the controller, and the temperature sensor is used to detect the temperature environment inside the carrier shell 1.

[0022] In an optional embodiment: the first vent 2 and the second vent 4 are both U-shaped and pass through the inside and outside of the carrier shell 1, the shielding frame 7 is U-shaped and matches the second vent 4, and a plurality of support blocks 41 are fixedly connected between the top and the bottom of the inner wall of the second vent 4. The support strength of the carrier shell 1 as a whole can be enhanced by the plurality of support blocks 41, and a cleaning brush 70 is connected to the side of the shielding frame 7 close to the second vent 4, and the cleaning brush 70 matches the second vent 4. When the filter screen 3 in the first vent 2 is to be cleaned, the shielding frame 7 can be controlled by the electric telescopic rod 6 to be close to the first vent 2, and the cleaning brush 70 can be used to clean the filter screen 3 in the first vent 2. The filter plate 3 is in conflict, and then the controller is controlled to repeatedly drive the shielding frame 7 to move up and down at a certain distance, so that the cleaning brush 70 on one side of the shielding frame 7 can effectively clean the filter plate 3. The thickness of the filter plate 3 can be set to 2mm-10mm, which can make the filter plate 3 thinner and allow the impurities in the holes of the filter plate 3 to be better cleaned. The carrier shell 1 is provided with a receiving groove 8 compatible with the cleaning brush 70 between the first air vent 2 and the second air vent 4. Under normal conditions, multiple shielding frames 7 are moved close to the receiving groove 8 to accommodate the cleaning brush 70 in the receiving groove 8, so that multiple shielding frames 7 can be placed inside the carrier shell 1.

[0024] Specifically, when the optical transmission communication module inside the carrier shell 1 operates normally, the second vent 4 is shielded by a plurality of shielding frames 7, which does not affect the normal heat dissipation inside the carrier shell 1. By starting the fan 5, the heat emitted by the optical transmission communication module inside the carrier shell 1 is dissipated through the filter screens 3 on the plurality of first vents 2 for heat dissipation. The temperature inside the carrier shell 1 is monitored by the temperature sensor 9, and the threshold of the temperature sensor 9 is preset by the controller. When the temperature inside the carrier shell 1 is too high and reaches the threshold, the temperature sensor 9 transmits a signal to the controller, and the controller controls the plurality of shielding frames 7 to move away from the second vent 4, so that the shielding frames 7 no longer shield the plurality of second vents 4, greatly improving the ventilation flow inside the carrier shell 1, allowing the heat inside the carrier shell 1 to be dissipated to the outside of the carrier shell 1 through the cooperation of the fan 5 in a short time, so that the inside of the carrier shell 1 can be effectively dissipated in a short time, and the optical transmission communication module inside the carrier shell 1 is prevented from being damaged due to excessive temperature.
