Description

Technical Field

[0001] The utility model relates to the technical field of power cabinets, in particular to a dustproof power cabinet. Background Art

[0002] The power cabinet is a commonly used power infrastructure, which contains a large number of power components. With the continuous advancement of urban construction, the standards for the construction and renovation of urban and rural power grids have increased significantly. The continuous reduction of overhead power lines and the continuous increase of underground cables have enabled the power cabinet to be used on a larger scale. For this reason, the reasonable design, selection and safe use of power cabinets have become an important part of the current power supply department's safe power supply.

[0003] The patent with application number 202020038798.X discloses a dustproof power cabinet, including a base plate and a cabinet body, the inner surface of the base plate is provided with an adjustment threaded hole, the inner surface of the adjustment threaded hole is threadedly connected with a fastening bolt, fixed sockets are provided on the left and right sides of the lower end of the cabinet body, the fixing sockets are fixedly connected with a support rod, the bottom of the support rod is fixedly connected with a support plate, and the inner surfaces of the left and right ends of the support plate are provided with mounting through holes, the inner surface of the upper left end of the cabinet body is provided with an exhaust duct, the inner surface of the upper right end of the cabinet body is provided with an air inlet duct, the left end of the inner cavity of the air inlet duct is provided with a dust filter, the left end of the top of the air inlet duct is fixedly installed with a motor, the output end of the motor is fixedly connected with a threaded rod, the outer surface of the threaded rod is threadedly connected with a movable block, and the left side of the movable block is fixedly connected with a brush.

[0004] The above scheme is adopted to solve the problem that the heat dissipation windows opened on the side walls of the current power cabinet easily allow dust to enter the cabinet, causing damage to the components inside the power cabinet and thus reducing its service life. However, although the above scheme can clean the dust on the dust filter, the cleaned dust will directly fall into the air inlet duct. Therefore, when the inlet fan is working, the dust will be re-drawn into the power cabinet, causing potential pollution and damage to the power components. In addition, the exhaust fan can easily discharge the dust inside the power cabinet onto the dustproof net during operation. After long-term operation, the dustproof net is easily blocked by dust, resulting in poor exhaust, thereby affecting the heat dissipation effect of the power cabinet. Utility Model Content

[0026] One end of the elastic spring 803 away from the round block 802 is fixedly connected to a connecting plate 804 , the interior of the connecting plate 804 is slidably connected to the rotating rod 801 , and a first handle 805 is fixedly connected to one side of the connecting plate 804 close to the elastic spring 803 .

[0027] A side of the connecting plate 804 away from the first handle 805 is fixedly connected to a limit fixing rod 806 , and one end of the limit fixing rod 806 away from the connecting plate 804 is slidably connected to the inside of the second dustproof filter element 15 .

[0028] The cleaning mechanism 9 comprises a silicone frame 901 installed on the inner wall of the square air outlet pipe 5 , and a first dustproof filter element 902 is fixedly connected to the inner side of the silicone frame 901 .

[0029] A vibration motor 903 is installed on a side of the first dustproof filter element 902 away from the exhaust fan 12 , and a vibration spring 904 is fixedly connected to a side of the first dustproof filter element 902 close to the vibration motor 903 .

[0031] The power cabinet 1 is used to accommodate and protect power components to ensure their safe operation.

[0032] The support foot 2 is used to support the power cabinet to ensure its stability and isolate the ground.

[0033] The exhaust fan 12 can exhaust the hot air inside the power cabinet.

[0034] The air inlet fan 13 can draw external cold air into the components inside the power cabinet to achieve a heat dissipation effect.

[0035] The rain shelter 4 is used to block rain and sunlight and helps to dissipate heat.

[0036] The air outlet square pipe 5 is responsible for exhausting the power cabinet, and a dustproof net is installed inside to prevent dust from entering.

[0037] The first dustproof net 6 is a component installed inside the air outlet square pipe 5, and is used to prevent dust from entering the power cabinet.

[0038] The quick-release mechanism 8 is provided at two locations, both of which are provided on the outer surface of the air inlet square tube 7 in a symmetrical state.

[0039] There are four vibration springs 904 and four square plates 905 , which are arranged at the four corners of the inner wall of the air outlet square tube 5 .

[0040] Working principle: When using the device, the inlet fan 13 works to draw the outside air into the interior of the power cabinet 1 through the air inlet square tube 7 to dissipate the heat of the electrical components inside the power cabinet 1, and then the exhaust fan 12 works to discharge the hot air inside the power cabinet 1 through the air outlet square tube 5. In this process, the dust from the outside will be blocked by the second dust filter element 15 and the second dust net 14 to prevent dust from entering the interior of the power cabinet 1 through the air inlet square tube 7. At the same time, the dust inside the power cabinet 1 will be blocked by the first dust screen plate 10 and the second dust screen plate 11 to prevent dust from entering the interior of the air outlet square tube 5 through the exhaust fan 12 and then attaching to the first dust filter element 902. The cleaning mechanism 9 is set to start the vibration motor 903. The vibration motor 903 works to drive the first dust filter element 902 to vibrate. Then, the elastic force of the vibration spring 904 and the silicone frame 901 can enhance the vibration effect of the first dust filter element 902. The dust attached to the first dust filter element 902 is shaken off to its outside, and then the dust can be blown out by the exhaust fan 12, thereby ensuring the permeability of the first dust filter element 902 and avoiding clogging of the first dust filter element 902, which would affect the heat dissipation effect of the power cabinet 1. At the same time, the silicone frame 901 can be set to prevent dust from entering the interior of the power cabinet 1 through the gap between the first dust filter element 902 and the air outlet square pipe 5. When the second dust filter element 15 needs to be cleaned or replaced, the first handle 805 can be pulled at this time, and the movement of the first handle 805 drives the connecting plate 804 to move, and the movement of the connecting plate 804 drives the limiting fixing rod 806 to move, so that the limiting fixing rod 806 no longer limits and fixes the second dust filter element 15. Then, the second dust filter element 15 can be pulled out from the interior of the air inlet square pipe 7 through the second handle 16, and the second dust filter element 15 can be cleaned or replaced. The operation is simple and convenient, and the practicability is strong.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
