Description

Technical Field

[0001] The present invention relates to the technical field of electrical cabinet protection, and specifically provides a protection system for electrical cabinets. Background Art

[0002] The protection system for electrical cabinets refers to the equipment and measures that provide protection and safety management for electrical cabinets. The protective shell is the main structure. Electrical cabinets are usually composed of metal shells, which are used to wrap and protect the internal electrical equipment and circuits. The shell can have functions such as waterproof, dustproof, and corrosion-resistant to ensure the normal operation of the equipment.

[0003] The prior art discloses an electrical cabinet for protective electrical engineering with the publication number: CN114585191A, including an electrical cabinet. An installation groove is opened on the front of the electrical cabinet. One side of the groove wall of the installation groove is provided with a connecting door. T-shaped chutes are opened at the top and bottom of the groove wall of the electrical cabinet, and two T-shaped sliders are slidably connected in each of the four T-shaped chutes. The beneficial effect of the present invention is that when the electrical device needs to be repaired, first open the connecting door, remove the fixing plate, and then the operator pulls the handle fixed on the front of the two support rods, so that the four support rods are pulled out of the electrical cabinet along with the T-shaped sliders, and then the electrical device fixed on the tray is pulled out, and then the operator can repair the electrical device, which is convenient for repairing the electrical device and reduces the time spent by the repairman in repairing the electrical device to a certain extent.

[0004] However, the above protection system for electrical cabinets does not have a diversion rainproof plate that can timely adjust the inclination angle according to different rain intensities when protecting against rainy weather. When the rain intensity is large, the rainproof plate is still relatively flat, which easily causes a large amount of rain to stop above, resulting in damage to the plate, and allowing rainwater to easily flow into the gap at the top of the electrical cabinet, affecting the use, and the effect during use is not good. Therefore, it is very necessary to design a device with strong practicability and good protection effect. Summary of the Invention

[0034] The diversion device 4 includes a diversion inclined plate 401, a receiving water tank 402 and a connecting water pipe fitting 403. The diversion inclined plate 401 is fixedly connected to the back of the guide plate 203. The receiving water tank 402 is fixedly connected to the back of the electrical cabinet 1.

One end of the connecting water pipe fitting 403 away from the bottom of the receiving water tank 402 is fixedly connected to the top of the water storage box 201.

[0035] During use, in rainy weather, the upper guide plate 203 can perform preliminary blocking, and the initial inclination angle of the guide plate 203 is not large, so the rainwater can be directed to the rainwater guide pipe 210, and then flow into the interior of the water storage box 201. After the rainwater fills the water storage box 201, it will flow into the interior of the rainwater pipe 202, and then the rainwater flows upward, pushing the limit slide bar 208 inside the rainwater pipe 202 to slide upward against the surfaces of the lower limit connecting disk 205 and the upper limit connecting disk 207, and then pushes the push piece 209 to move upward, and the top of the push piece 209 contacts the bottom of the connecting plate 204, and the connecting plate 204 and The guide plate 203 is fixedly connected near the front side, so the front end of the guide plate 203 can be continuously pushed up to form a continuously increasing inclination angle, so that rainwater can flow down faster, and the inclination angle cannot be too large, so after adjusting to a certain degree, the hydraulic telescopic rod 302 needs to be started to drive the fitting slide plate 304 and the placement plate 303 to move upward, and the placement plate 303 is connected to the connecting slide plate 301, so the connecting slide plate 301 and the upper placement vertical plate 305 and other components can be driven to move upward synchronously until the connecting slide plate 301 slides to the top of the surface of the rainwater guide pipe 210, and then the driving stepper motor 306 can be started to drive the inner The connecting shaft 307 rotates 180 degrees counterclockwise, driving the baffle plate 308 to press the sealing gasket 309 and flip it synchronously, so that the bottom of the baffle plate 308 can contact the top of the rainwater diversion pipe 210, and the sealing gasket 309 can be inserted into the interior of the rainwater diversion pipe 210, thereby blocking the top of the rainwater diversion pipe 210, which can prevent rainwater from flowing out and in, and can ensure the balance of the angle of the jacking guide plate 203. Then, when it stops raining, the water can be discharged, and the mounting bolts 215 are turned to make the connection effect between the sealing plate 214 and the connecting seat 213 disappear, and then the sealing plate 214 is removed to let the rainwater flow out. The entire protection and rainproof function is completed, and a guide inclined plate 401 is arranged on the back of the guide plate 203, which can receive part of the rainwater in cooperation with the receiving water tank 402, and let it flow into the connecting water pipe 403 and finally flow into the water storage box 201, which can accelerate the speed of the angle change of the guide plate 203, so that the protection system for the electrical cabinet can be provided with a guide rainproof plate component that can adjust the inclination angle in time according to different rain intensity when protecting against rainy weather. When the rain intensity is heavy, the rainproof plate component will not be relatively flat, which will not cause heavy rain above and cause damage to the plate component, and will not allow rainwater to easily flow into the gap on the top of the electrical cabinet to affect its use, and the effect is good when used.
