Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and specifically to an outdoor switch cabinet. Background Art

[0002] As an important part of the power system, the reliability and safety of outdoor switch cabinets are directly related to the stable operation of the power grid. In the outdoor environment, switch cabinets are exposed to natural conditions for a long time. They not only need to withstand extreme temperature changes but also face the influence of harsh climates such as wind, rain, and sand and dust. To ensure the normal operating temperature of the electrical components inside the switch cabinet, the prior art generally adopts the design of installing louvers on both sides of the cabinet body to utilize natural wind for ventilation and heat dissipation to prevent the equipment from overheating. The louver structure can adjust the air circulation volume, which can provide necessary ventilation when needed and block foreign objects from entering to a certain extent.

[0003] When the existing outdoor switch cabinets are in use, they have certain limitations in the face of harsh weather conditions, especially heavy rain. When the rainfall is large, the louvers cannot be closed in time, allowing rainwater to enter between the ventilation openings and the fan blades. The rainwater directly impacts the louvers, causing the rainwater to enter through the gaps between the window leaves and the ventilation openings or splash back into the ventilation openings from the rainwater splashed on the ground, resulting in the interior of the switch cabinet getting damp and thus affecting the use of the switch cabinet. Summary of the Invention

[0004] The purpose of the present invention is to provide an outdoor switch cabinet, which solves the problem of rainwater entering the ventilation openings when the rainfall is large by providing an energy storage part and a guide plate to close the ventilation openings.

[0005] The present invention is realized through the following technical solutions:

[0006] The present invention is an outdoor switch cabinet, including a switch cabinet main body, a connecting part, and a guide plate. Windows are installed on both sides of the switch cabinet main body. The window has a window frame, a horizontal axis, and window leaves. A first perforation for mating with the horizontal axis is opened in the window leaf, and a row of horizontal holes is opened in the window frame. The horizontal axis is fitted in the ventilation opening. The connecting part has a sprocket and a chain. Sprockets are sleeved on the ends of a row of horizontal axes, and a row of sprockets is connected by a chain. A second perforation is opened on the guide plate. A horizontal block is installed on the outer surface of the switch cabinet main body, and a through hole is opened on the horizontal block. The end of the horizontal axis is sequentially fitted in the through hole and the second perforation from left to right. A torsion spring is sleeved on the horizontal axis, and the two ends of the torsion spring are respectively connected to the outer surfaces of the horizontal block and the corresponding guide plate.

[0007] An energy storage part is installed on the outer surface of the switch cabinet main body, and the energy storage part touches the outer surface of the end of the guide plate.

[0008] Furthermore, a ventilation opening is opened in the window frame, and the window leaf is located in the ventilation opening.

[0009] Furthermore, a stop block is installed on the outer surface of the window frame, and the stop block touches the top of the guide plate.

[0010] Furthermore, the energy storage part has a water storage device and a piston. A cavity is formed inside the water storage device. The piston is slidably fitted inside the cavity. A vertical rod is connected to the bottom of the piston, and the bottom end of the vertical rod touches the outer surface of the end of the guide plate. A circular ring is installed inside the cavity.

[0011] Furthermore, the bottom end of the vertical rod is spherical.

[0012] Furthermore, a drain port and an exhaust port are successively formed from top to bottom inside the water storage device. The piston is located above the drain port. A water outlet pipe is fitted to the water storage device, and a sealing plug is threadedly fitted to the water outlet pipe.

[0013] Furthermore, a rain shield is installed on the top of the switch cabinet main body. Drainage grooves and diversion cross grooves are formed on both sides of the rain shield. The drainage grooves communicate with the diversion cross grooves. A row of diversion vertical grooves is formed on the rain shield, and the diversion cross grooves communicate with the row of diversion vertical grooves.

[0014] Furthermore, the top of the water storage device has an inclined surface opening which communicates with the cavity, and the end of the drainage groove is located on the inclined surface opening.

[0015] Furthermore, a filtering part is installed on the top of the energy storage part. The filtering part has a baffle and a filter screen. The baffle is located on the top of the inclined surface opening, and the filter screen is installed on the side of the baffle.

[0016] The present invention has the following beneficial effects:

[0017] In the present invention, the energy storage part and the guide plate are provided to close the ventilation opening. Under heavy rain or strong rainfall conditions, the energy storage part triggers the guide plate to rotate, driving the horizontal shaft and the window leaf to close the ventilation opening of the window body, effectively blocking the intrusion of rainwater, reducing the risk of moisture inside the switch cabinet main body, enhancing the self - protection ability of the switch cabinet body in bad weather, reducing the water leakage problem at the ventilation opening gap caused by rain sputtering or wind pressure, and thus improving the overall stability and safety of the power system;

[0018] In the present invention, the water storage device, the piston and the vertical rod are provided to push the guide plate. By introducing a rainwater collection container and a piston - pushing mechanism, a more sensitive and precise response to rainstorm changes is achieved. When heavy rain comes, rainwater quickly enters the water storage device, the piston moves downward under the action of gravity, driving the vertical rod to move and push the guide plate, realizing the closing of the automatic window leaf, and improving the reliability and stability of the device;

[0019] The present invention filters the water entering the energy storage part through the provided baffle and filter screen. During the process of water being introduced into the cavity through the drainage groove on the rain shield, the filter screen filters the water. At the same time, since the baffle is arranged at the inclined plane opening, it can prevent leaves and the like from being blocked at the top of the cavity during rainfall through the baffle, increasing the stability of water intake, avoiding the blockage problem of the cavity, and thus increasing the practicality of the device.

[0020] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6, the present invention provides a technical solution: an outdoor switchgear cabinet, including a switchgear cabinet main body 1, a connecting part and a guide plate 5. Windows 4 are installed on both sides of the switchgear cabinet main body 1. The window 4 has a window frame 401, a horizontal shaft 403 and a window leaf 404. A ventilation opening 402 is provided in the window frame 401. The window leaf 404 is located in the ventilation opening 402. In the normal state, there is a certain angle between the window leaf 404 and the ventilation opening 402 to facilitate air intake and ventilation. When it rains, the vertical rod 305 of the energy storage part 3 pushes the guide plate 5 to rotate a certain angle. At this time, it drives the horizontal shaft 403 to make the window leaf 404 rotate to close the ventilation opening 402. A stop block 6 is installed on the outer surface of the window frame 401. The top of the stop block 6 touches the top of the guide plate 5. When the torsion spring 8 drives the guide plate 5 to return to its original position, the top of the guide plate 5 touches the bottom of the stop block 6 to prevent the rotation amplitude from being too large and causing the window leaf 404 and the ventilation opening 402 to be unable to ventilate. A first through hole for fitting the horizontal shaft 403 is provided in the window leaf 404. A row of horizontal holes 407 is provided in the window frame 401. The horizontal shaft 403 is fitted in the ventilation opening 402. The connecting part has a sprocket 405 and a chain 406. The ends of a row of horizontal shafts 403 are all sleeved with sprockets 405. A row of sprockets 405 is connected by a chain 406. A second through hole is provided on the guide plate 5. A cross block 7 is installed on the outer surface of the switchgear cabinet main body 1. A through hole is provided on the cross block 7. The end of the horizontal shaft 403 is sequentially fitted in the through hole and the second through hole from left to right. A torsion spring 8 is sleeved on the horizontal shaft 403. The two ends of the torsion spring 8 are respectively connected to the corresponding outer surfaces of the cross block 7 and the guide plate 5. When encountering heavy rain in bad weather, the rain makes the vertical rod 305 of the energy storage part 3 move downward. Since the end of the vertical rod 305 contacts the outer surface of the end of the guide plate 5, at this time, it pushes the guide plate 5 to rotate and drives the horizontal shaft 403 to rotate a certain angle until the vertical rod 305 descends to the bottom. At this time, the guide plate 5 is in an inclined state and contacts the spherical bottom of the vertical rod 305. Then, a row of sprockets 405 is connected by a chain 406, so that a row of horizontal shafts 403 rotate simultaneously to drive the window leaf 404 to close the ventilation opening 402. After the rain stops, the vertical rod 305 can no longer limit the guide plate 5, so that the rebound of the torsion spring 8 drives the guide plate 5 to rotate back and then drives the horizontal shaft 403 to rotate to make the window leaf 404 open a certain angle until the top surface of the guide plate 5 touches the bottom of the stop block 6. At this time, the guide plate 5 pushes the vertical rod 305 back to its original position.

[0030] An energy storage part 3 is installed on the outer surface of the main body 1 of the switch cabinet. The energy storage part 3 is in contact with the outer surface of the end of the guide plate 5. The energy storage part 3 has a water storage device 301 and a piston 304. A drain port 307 and an exhaust port 308 are successively arranged in the water storage device 301 from top to bottom. When rainwater enters the interior of the cavity 302, due to the gravity of the water, the piston 304 moves downward. At this time, the air in the gap between the piston 304 and the bottom wall of the cavity 302 is discharged from the exhaust port 308. The piston 304 is located above the drain port 307. A water outlet pipe 309 is fitted on the water storage device 301, and a sealing plug 310 is in threaded fit on the water outlet pipe 309. When it is necessary to drain the water inside the cavity 302, at this time, the sealing plug 310 is rotated so that the water is discharged from the water outlet pipe 309. The top of the water storage device 301 has an inclined surface opening 303, and the inclined surface opening 303 is communicated with the cavity 302. The end of the drain groove 201 is located on the inclined surface opening 303. By providing the inclined surface opening 303, the top of the water storage device 301 is in the shape of a funnel, so that when the water is diverted from the end of the drain groove 201 into the water storage device 301, the opening is increased to facilitate the entry of water. A cavity 302 is provided inside the water storage device 301, and the piston 304 is slidably fitted in the cavity 302. A vertical rod 305 is connected to the bottom of the piston 304, and the bottom end of the vertical rod 305 is spherical. Since the bottom end of the vertical rod 305 is spherical, whether the vertical rod 305 pushes the guide plate 5 downward or the guide plate 5 returns to push the vertical rod 305 upward, there will be no too much blockage, reducing friction. The bottom end of the vertical rod 305 is in contact with the outer surface of the end of the guide plate 5. A circular ring 306 is installed in the cavity 302. During rainfall, the rainwater is diverted from the inclined surface opening 303 into the cavity 302. When the weight is certain, it will push the piston 304 downward to drive the vertical rod 305 to move downward to push the guide plate 5 to rotate until the piston 304 is located below the drain port 307. At this time, the rainwater accumulated inside the cavity 302 flows out from the drain port 307. If it keeps raining, at this time, the rainwater continuously enters the cavity 302 to exert pressure on the piston 304, so that the torsion spring 8 cannot rebound. When the rain stops, since the rainwater inside the cavity 302 cannot be replenished, after being discharged from the drain port 307, the pressure on the piston 304 cannot support the rebound of the torsion spring 8, so that the torsion spring 8 drives the guide plate 5 to return, and then drives the vertical rod 305 to move the circular ring 306 upward until the top of the piston 304 touches the circular ring 306, and the piston 304 is limited by the circular ring 306.

[0031] A rain shield 2 is installed on the top of the switchgear main body 1. The switchgear main body 1 can be protected by the provided rain shield 2. Drainage grooves 201 and diversion cross grooves 203 are formed on both sides of the rain shield 2. The drainage grooves 201 are communicated with the diversion cross grooves 203. A row of diversion vertical grooves 202 are formed on the rain shield 2. The diversion cross grooves 203 are communicated with a row of diversion vertical grooves 202. During rainfall, rainwater flows through a row of diversion vertical grooves 202 to the end and then converges into the diversion cross grooves 203, and enters the drainage grooves 201 from the diversion cross grooves 203, so that the rainwater can be discharged into the water storage device 301 from the drainage grooves 201.

[0032] A filtering part 9 is installed on the top of the energy storage part 3. The filtering part 9 has a baffle 901 and a filter screen 902. There are through openings at the bottom of the baffle 901 and the side plate close to the rain shield 2, and the two openings are communicated. The baffle 901 is located at the top of the inclined surface opening 303. The filter screen 902 is installed on the side of the baffle 901. During the process of water being introduced into the cavity 302 through the drainage grooves 201 on the rain shield 2, the filter screen 902 filters the water. At the same time, since the baffle 901 is arranged on the inclined surface opening 303, it can prevent leaves and the like from being blocked at the top of the cavity 302 during rainfall.
