[0027] like Figures 1 to 3, a noise reduction device for a power distribution room, comprising a power distribution room body 1 and an air outlet pipe 3 with a fan 2, the air outlet pipe 3 penetrates and is fixedly connected to the side wall of the power distribution room body 1, wherein the air outlet pipe 3 can be circular or rectangular, and is mainly used for transmitting airflow;

[0028] The noise reduction device in the utility model also includes:

[0029] A movable baffle 4, wherein the movable baffle 4 is driven to slide in a vertical direction and is connected to the air outlet of the air outlet pipe 3, and is mainly used to shield the air outlet of the air outlet pipe 3, and the air outlet is located at one end of the air outlet pipe 3 close to the inside of the power distribution room body 1;

[0030] A moving block 5 is elastically slidably connected to one end of the moving baffle 4 near the air outlet, and the elastic connection of the moving block 5 is connected through a spring 17, which is fixedly connected in the moving baffle 4 and one end of which is fixedly connected to the moving block 5, so that the moving block 5 can be reset;

[0031] Sound insulation cotton 6, which is fixedly connected to the end of the moving block 5 away from the spring 17. The sound insulation cotton 6 is mainly used to seal the air outlet to achieve the sound insulation effect;

[0032] The movable block 27 is elastically slidably connected to one end of the movable baffle 4 near the air outlet, and the elastic sliding connection of the movable block 27 is connected through a spring 218, which is fixedly connected to the movable baffle 4 and one end of which is fixedly connected to the movable block 27, so that the movable block 27 can be reset;

[0033] The sound insulation cotton 28 is fixedly connected to the end of the moving block 27 away from the spring 218, and is mainly used to seal the air outlet pipe 3. It is worth mentioning that the shapes of the moving block 27 and the sound insulation cotton 28 are the same as the shape of the end face of the air outlet pipe 3. The sound insulation cotton 28 is attached to the air outlet pipe 3, so that the air outlet pipe 3 can be sealed, thereby achieving the effect of sound insulation.

[0034] Specifically, a temperature sensor 9 is fixedly connected inside the distribution room body 1. The temperature sensor 9 is mainly used to sense temperature. When the temperature inside the distribution room body 1 rises to a certain temperature, the temperature sensor 9 transmits a signal to a control panel 10 fixedly connected inside the distribution room body 1 and electrically connected thereto. The control panel 10 controls the fan 2 electrically connected thereto to start, thereby achieving heat dissipation inside the distribution room body 1 by the fan 2.

[0035] Specifically, an electric push rod 11 is fixedly connected to the air outlet duct 3 and is electrically connected to the control panel 10 through the electric push rod 11. Therefore, when the control panel 10 receives a temperature rise and controls the electric push rod 11 to start, the electric push rod 11 will drive the movable baffle 4 fixedly connected to its output shaft to move, thereby realizing the transmission of airflow by the air outlet duct 3. It is worth mentioning that when the temperature in the distribution room body 1 is not lowered, the air outlet duct 3 is in a sealed state.

[0037] Specifically, the limit plate 13 is fixedly connected to the air outlet 3, and the sliding rod 14 is slidably connected to the limit plate 13. Therefore, when the movable baffle 4 moves, the sliding rod 14 is fixedly connected to the movable baffle 4, so that the sliding rod 14 can support the movable baffle 4.

[0038] Specifically, a baffle plate 15 arranged in an arc shape is fixedly connected to the moving block 5, and the sound insulation cotton 6 is located in the baffle plate 15, and contacts with the air outlet pipe 3 through the baffle plate 15, thereby increasing the protection effect of the sound insulation cotton 6.

[0039] Specifically, an arc-shaped baffle plate 16 is fixedly connected to the moving block, and the sound insulation cotton 8 is displaced into the baffle plate 16, thereby increasing the protective effect of the sound insulation cotton 8.

[0040] Principle of the utility model: the movement of the movable baffle 4 drives the movement of the movable block 5. When the movable block 5 moves to the air outlet close to the air outlet duct 3, when the movable block 5 is close to the air outlet, the movable block 5 will drive the sound insulation cotton 6 to enter the air outlet duct 3, so that the sound insulation cotton 6 seals the air outlet duct 3, thereby achieving the sealing of the air outlet duct 3. When the movable block 27 moves to the end face close to the air outlet duct 3, the movable block 27 pushes the sound insulation cotton 28 to stick to the air outlet duct 3, thereby achieving the sealing of the air outlet duct 3 by the sound insulation cotton 28, thereby indirectly achieving the sound insulation of the air outlet duct 3 and reducing the transmission of the sound source to the outside through the air outlet duct 3.

[0041] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
