Description

Technical Field

[0001] The invention relates to the technical field of power cabinets, in particular to a power cabinet which is convenient for heat dissipation. Background Art

[0002] As the name implies, a power cabinet refers to an object used to contain and protect electrical equipment. In the contemporary power grid, electrical equipment is an important part of its composition. Therefore, in the entire power grid, a large number of power cabinets are needed to contain and protect electrical equipment. When the power cabinet is in use, the electronic devices inside it will generate a lot of heat. If the heat is not dissipated inside the power cabinet, it is easy to cause heat accumulation and damage to the electronic devices. In the prior art, the power cabinet usually uses a cooling fan to suck the external airflow into the inner cavity of the power cabinet to dissipate the heat of the heating devices in the power cabinet. However, the internal space of the power cabinet is usually large, and the airflow sucked into the inner cavity of the power cabinet by the cooling fan gradually diverges to the surroundings, which makes the sucked airflow unable to act well on the main heating device, thereby limiting the heat dissipation efficiency of the cooling fan on the main heating device. In addition, there is a lack of a complete airflow passage in the inner cavity of the power cabinet, which makes it difficult for the airflow carrying the heat of the main heating device to be evacuated to the outside of the power cabinet, which is easy to cause heat accumulation of the main heating device. For this reason, the present invention provides a power cabinet that is easy to dissipate heat. Summary of the invention

[0024] Working principle: When in use: when the staff closes the cabinet door 2, the side of the sliding rod 51 away from the cabinet door 2 abuts against the baffle 3. As the cabinet door 2 continues to close, the side of the sliding rod 51 away from the cabinet door 2 continuously moves toward the inner cavity of the shell 4 under the action of the baffle 3, so that the sliding rod 51 drives the circular plate 52 to move, and the circular plate 52 drives the rack 6 to move. In this process, the spring 53 is stretched under force; due to the meshing relationship between the rack 6 and the gear 1 72, the rack 6 will drive the gear 1 72 to rotate during the movement, and the gear 1 72 drives the transmission rod 1 71 to rotate, the transmission rod 1 71 drives the gear 2 73 to rotate, the rotating gear 2 73 drives the gear 3 82 to rotate, the gear 3 82 drives the transmission rod 2 81 to rotate, the transmission rod 2 81 drives the first bevel gear 83 to rotate, the rotating first bevel gear 83 drives the second bevel gear 92 to rotate, and the second bevel gear 92 drives the worm 91 to rotate The rotating worm 91 drives the worm wheel 142 to rotate, the worm wheel 142 drives the threaded rod 141 to rotate, and the internal threaded barrel 143 moves along the thread direction of the threaded rod 141; since the side of the internal threaded barrel 143 away from the cabinet door 2 is fixedly connected to the side wall of the mounting plate 12, and the mounting plate 12 is fixedly connected to the upper part of the inner sleeve 11, the internal threaded barrel 143 pushes the inner sleeve 11 to move toward the main heating device inside the cabinet 1, so that the inner sleeve 11 is close to the main Heating device; when the cabinet door 2 is completely closed, the cooling fan 17 is set to suck the external airflow into the inner cavity of the cabinet 1, and the external airflow passes through the air inlet duct 16, the outer sleeve 10 and the inner sleeve 11 in sequence and enters the inner cavity of the cabinet 1. Since the outer sleeve 10 is close to the main heating device, the external airflow directly acts on the main heating device in a direct blowing manner, which makes the sucked airflow act well on the main heating device, thereby improving the heat dissipation efficiency of the cooling fan 17 on the main heating device; In addition, when the cabinet door 2 is opened, the inner sleeve 11 is retracted into the outer sleeve 10 under the elastic force of the spring 53, thereby reducing the space occupied by the inner sleeve 11, thereby facilitating subsequent staff to inspect and repair the components inside the cabinet 1; In addition, the cooling fan 2 192 is arranged to operate synchronously with the cooling fan 1 17, and the airflow carrying the heat of the main heating components is evacuated to the outside of the cabinet 1 through the wind collecting hood 191 and the air outlet duct 193 in sequence.
