Description

Technical Field

[0001] The utility model relates to the technical field of switch equipment protection, in particular to a protective shell of a switch equipment. Background Art

[0002] In order to provide a temperature-appropriate environment for the switchgear, the switchgear is generally installed in a cabinet, and a fan is installed on the cabinet for ventilation and heat dissipation.

[0003] In the related technology, a solution of a protective casing for power distribution control equipment (Announcement No. CN217956486U) was found through searching. Through the ventilation and heat dissipation mechanism, when the protective casing needs to be ventilated and dissipated, the air cooler can be turned on to rotate. The rotation of the air cooler will drive the movable baffle fixedly connected to it to rotate. When the movable baffle rotates, the inside of the protective casing will be connected to the outside through the heat dissipation holes, thereby achieving the effect of ventilation. In addition, while ventilating, the air cooler continuously rotates to blow out cold air, which can also dissipate heat and cool down the inside of the protective casing.

[0004] However, the heat dissipation method adopted in the above scheme is widely used in the protection of switch equipment. Since air is blown into the casing, dust prevention treatment is also required to avoid dust accumulation in the casing. The commonly used dust prevention method in the industry is to use a dust net, and the dust net is generally set on the side or back of the casing. When cleaning the dust net, the casing needs to be moved, which is not easy to operate, especially when multiple casings are arranged together; in addition, most of the time, the air cooler is used to blow air into the casing, which is difficult to dissipate heat for switch equipment with high heat generation, and the heat dissipation capacity needs to be improved.

The air entering the housing 1 is first filtered and dusted by the first filter screen 4, so as to prevent dust from entering the housing 1 and play a dust-proof role;

[0024] An air inlet box 13, the air inlet box 13 is mounted to the bottom of the housing 1, an air inlet fan 15 and a plurality of exhaust nozzles 14 are mounted on the surface of the air inlet box 13, the air inlet box 13 is provided with a support rod 19 and a bellows 18, the bellows 18 covers the air inlet fan 15, a fitting frame 16 is provided at the right end of the bellows 18, and the fitting frame 16 is in contact with the first filter screen 4, and a spring 22 is provided between the fitting frame 16 and the support rod 19;

[0025] The bellows 18 can be extended and retracted. When the door panel 2 is closed, the door panel 2 and the fitting frame 16 are pushed to move, and the fitting frame 16 compresses the spring 22. At this time, the elastic force of the spring 22 pushes the fitting frame 16 to fit with the first filter 4, ensuring that the air intake fan 15 draws air outside the shell 1, allowing the air inside the shell 1 to circulate.

[0026] In this embodiment, if Figure 2 and Figure 4As shown, a right-angle plate 11 is provided on the upper inner wall of the shell 1, and a plurality of exhaust fans 12 are installed inside the right-angle plate 11. A plug hole 21 is provided on the surface of the exhaust fan 12, and a connecting bar 20 is installed inside the plug hole 21. The connecting bar 20 can splice two exhaust fans 12 together, making the installation of the exhaust fan 12 more convenient and eliminating the need for screw installation.

[0027] In this embodiment, if Figure 1 As shown, a limit frame 5 is provided on the upper surface of the shell 1, and a second filter 6 is inserted into the limit frame 5, and the second filter 6 covers the exhaust port. The second filter 6 can prevent dust from falling into the shell 1, and the second filter 6 can be pulled out from the limit frame 5 to facilitate cleaning of the second filter 6.

[0028] In this embodiment, if Figure 1 As shown, a plurality of limit buckles 3 are provided on the surface of the door panel 2, and the first filter screen 4 is inserted between the limit buckles 3 and the door panel 2, so as to clamp the first filter screen 4, and the first filter screen 4 can be directly pulled out when cleaning.
