Description

Technical Field

[0001] The present invention relates to the technical field of power station grid connection cabinet equipment, and specifically relates to a high-efficiency distributed photovoltaic power station grid connection cabinet. Background Art

[0002] The installed capacity of distributed photovoltaic power stations continues to grow, and the application scenarios cover multiple fields such as industrial factories, commercial buildings, and residential houses.

[0012] The present invention has the following beneficial effects: 1. In the present invention, when using the cabinet body, the motor is started. When the motor works, it drives the fan shaft and the cross plate to rotate. When the fan shaft rotates, it blows the heat inside the main body towards the filter screen at the top of the main body. Subsequently, when the fan shaft drives the cross plate to rotate, the rotation of the cross plate drives multiple tooth shafts to rotate synchronously on the inner wall of the tooth ring. When the tooth shaft rotates with the cross plate, it rotates self - synchronously through meshing with the tooth ring. When the tooth shaft rotates, it drives the spherical rod to rotate through the obtuse - angle plate. When the spherical rod rotates, it drives the fixed ring two to rotate through the sliding block. Subsequently, when the spherical rod continues to rotate, it drives the sliding block to slide back and forth on the fixed ring two. When the spherical rod drives the sliding block to slide back and forth, it drives the intermediate plate to slide synchronously through the sliding disk. When the intermediate plate slides back and forth with the sliding block, it drives the crank rod to rotate in a manner similar to a crank. When the crank rod rotates, it extracts the gas outside the filter screen through the fan plate at the top. When the gas is extracted, it enters the spray pipe through the connecting frame two and the fixed cylinder and is sprayed out through the spray pipe. At the same time, when the rotation of the spherical rod drives the fixed ring two to rotate through the sliding block, the rotation of the fixed ring two drives the spring rod to rotate synchronously through the sliding block. When the sliding block rotates, it drives the spray pipe for jetting to shake. At this time, when the spray pipe jets and shakes, it can spray the extracted gas dispersedly into the interior of the main body, which can promote the full mixing of the cool air entering from the outside and the hot air inside the main body, thereby accelerating the heat exchange and improving the heat dissipation efficiency of the hot gas inside the main body.

[0013] 2. In the present invention, when the cross plate drives the gear shaft to rotate, the rotating gear shaft will drive a plurality of spring shafts to rotate synchronously. When the spring shafts rotate with the cross plate, the raised rings on the spring shafts will slide inside the undulating grooves and be guided by the undulating grooves during the sliding process, thereby enabling up and down sliding. At the same time, when the plurality of gear shafts rotate around their own axes as the cross plate rotates, they will drive the annular plate to perform eccentric rotation through the spring shafts. When the spring shafts slide upward, the sliding of the spring shafts will drive the annular plate and the elliptical plate to move upward synchronously. Subsequently, when the fan shaft rotates, the rotation of the fan shaft will blow some hot gas into the interior of the elliptical plate. Then, when the elliptical plate moves upward, it will squeeze the filter screen at the top of the main body. Subsequently, the elliptical plate will receive the reaction force from the filter screen and thus can produce a relatively closed motion state. At this time, the closed elliptical plate will squeeze the gas inside, and the gas will be ejected through the air outlet holes to spray the filter screen when the elliptical plate and the annular plate rotate. When the filter screen is sprayed by the gas, the adhesion of dust on the filter screen can be reduced, thereby reducing the situation where heat dissipation is affected by the adhesion of dust and improving the heat dissipation efficiency.

[0014] 3. In the present invention, when the elliptical plate slides upward with the spring shaft, the upward sliding of the elliptical plate will impact the filter screen. At this time, the elliptical plate will receive the reaction force from the filter screen and produce relative closure. When the elliptical plate is closed, an elastic buffer layer can be formed when the elliptical plate impacts the filter screen to absorb the impact on the filter screen, thereby reducing the situation where the filter screen is deformed due to excessive impact force when the elliptical plate impacts the filter screen, thus reducing the direct impact on the filter screen and ensuring the filtering effect.

[0015] 4. In the present invention, when the elliptical plate is closed under the extrusion of the filter screen, the closing of the elliptical plate will push the fixed plate to move backward. When the fixed plate moves backward, it will drive the rotating shaft to rotate through the insertion rod inside the round hole in the threaded groove on the rotating shaft. When the rotating shaft rotates, it will drive the vertical plate to rotate upward through the auxiliary plate. When the vertical plate rotates upward, it will drive the sliding frame to move upward synchronously. At the same time, when the rotating shaft rotates, it will squeeze the bottom of the sliding plate through the cam disc. After being squeezed, the sliding plate will slide downward inside the sliding frame. When the sliding plate slides downward in the fixed frame, it will extract the external gas through the area between the sliding plate and the top inner wall of the sliding frame through the one-way pipe. When the gas is extracted, it will enter the sliding frame. Subsequently, when the cam disc continues to rotate, it will push the sliding plate to move backward. When the sliding plate slides to the horizontal position on the cam disc, it will quickly squeeze the gas inside the sliding frame under the tension of the tension spring. At the same time, when the sliding frame slides upward, the sliding frame will make the rotating disc contact the side wall of the filter screen. At the same time, the inclined block will push the spring plate to expand outward under the extrusion of the filter screen. At this time, the expanded spring plate will squeeze the side wall of the elliptical plate, thereby reducing the contact between the elliptical plate and the filter plate. At the same time, the rotating disc will rotate between the filter screen and the elliptical plate along with the annular plate. At the same time, when the sliding plate quickly squeezes the gas inside the sliding frame, the gas can be ejected onto the filter screen through the holes on the air outlet ring. Combining with the rotation of the rotating disc on the filter screen can further improve the cleaning of the filter screen and at the same time reduce the contact area between the elliptical plate and the filter screen during rotation, reducing the situation that the elliptical plate rotates unstably or vibrates due to the large contact area between the elliptical plate and the filter plate, thereby further improving the cleaning effect of the filter screen.

[0016] 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

[0029] During use, the motor 201 is started when using the cabinet body. When the motor 201 is working, it drives the fan shaft 202 and the cross plate 203 to rotate. When the fan shaft 202 rotates, it blows the heat inside the main body 1 towards the top filter screen of the main body 1. Subsequently, when the fan shaft 202 drives the cross plate 203 to rotate, the rotation of the cross plate 203 drives a plurality of tooth shafts 204 to rotate synchronously on the inner wall of the tooth ring 103. When the tooth shaft 204 rotates with the cross plate 203, it rotates self - synchronously through meshing with the tooth ring 103.

When the gas is extracted, it enters the spray pipe 502 through the connecting frame two 503 and the fixed cylinder 404 and is sprayed outwards through the spray pipe 502. At the same time, when the rotation of the spherical rod 302 drives the fixed ring two 304 to rotate through the sliding block 303, the rotation of the fixed ring two 304 drives the spring rod 306 to rotate synchronously through the sliding block 303.

[0030] When the cross plate 203 drives the gear shaft 204 to rotate, the rotating gear shaft 204 will drive a plurality of spring shafts 601 to rotate synchronously. When the spring shaft 601 rotates with the cross plate 203, the raised rings on the spring shaft 601 will slide inside the undulating groove and be guided by the undulating groove during the sliding, so as to slide up and down. At the same time, when a plurality of gear shafts 204 rotate around their own axes with the rotation of the cross plate 203, they will drive the annular plate 602 to perform eccentric rotation through the spring shaft 601. When the spring shaft 601 slides upward, the sliding of the spring shaft 601 will drive the annular plate 602 and the elliptical plate 603 to move upward synchronously. Subsequently, when the fan shaft 202 rotates, the rotation of the fan shaft 202 will blow part of the hot gas into the interior of the elliptical plate 603. Then, when the elliptical plate 603 moves upward, it will squeeze the filter screen at the top of the main body 1. Subsequently, the elliptical plate 603 will receive the reaction force from the filter screen and thus can produce a relatively closed motion state. At this time, the closed elliptical plate 603 will squeeze the gas inside, and the gas will be ejected through the air outlet holes to the filter screen when the elliptical plate 603 and the annular plate 602 rotate. When the filter screen is sprayed with gas, the adhesion of dust on the filter screen can be reduced, thereby reducing the situation that the heat dissipation is affected by the adhesion of dust and improving the heat dissipation efficiency.

[0031] When the elliptical plate 603 slides upward with the spring shaft 601, the upward sliding of the elliptical plate 603 will impact the filter screen. At this time, the elliptical plate 603 will receive the reaction force from the filter screen and produce relative closure. When the elliptical plate 603 is closed, an elastic buffer layer can be formed when the elliptical plate 603 impacts the filter screen to absorb the impact on the filter screen, thereby reducing the situation that the filter screen is deformed due to excessive impact force when the elliptical plate 603 impacts the filter screen, thus reducing the direct impact on the filter screen and ensuring the filtering effect.

[0032] When the elliptical plate 603 is closed under the extrusion of the filter screen, the closing of the elliptical plate 603 will push the fixed plate 701 to move backward. When the fixed plate 701 moves backward, it will drive the rotating shaft 702 to rotate through the threaded groove of the insertion rod inside the circular hole on the rotating shaft 702. When the rotating shaft 702 rotates, it will drive the vertical plate 801 to rotate upward through the auxiliary plate. When the vertical plate 801 rotates upward, it will drive the sliding frame 704 to move upward synchronously. At the same time, when the rotating shaft 702 rotates, it will extrude the bottom of the sliding plate 803 through the cam disc 802. After the sliding plate 803 is extruded, it will slide downward inside the sliding frame 704. When the sliding plate 803 slides downward in the fixed frame 703, it will extract the external gas through the area between the sliding plate 803 and the top inner wall of the sliding frame 704 through the one-way pipe. When the gas is extracted, it will enter the sliding frame 704. Subsequently, when the cam disc 802 continues to rotate, it will push the sliding plate 803 to move backward. When the sliding plate 803 slides to the horizontal position on the cam disc 802, it will quickly extrude the gas inside the sliding frame 704 under the tension of the tension spring. At the same time, when the sliding frame 704 slides upward, the sliding frame 704 will make the rotating disc contact the side wall of the filter screen. At the same time, the inclined block 706 will push the spring plate 707 to expand outward under the extrusion of the filter screen. At this time, the expanded spring plate 707 will extrude the side wall of the elliptical plate 603, thereby reducing the contact between the elliptical plate 603 and the filter plate. At the same time, the rotating disc will rotate with the annular plate 602 between the filter screen and the elliptical plate 603. At the same time, when the sliding plate 803 quickly extrudes the gas inside the sliding frame 704, the gas can be sprayed onto the filter screen through the holes on the air outlet ring 705. Combining with the rotation of the rotating disc on the filter screen can further improve the cleaning of the filter screen and at the same time reduce the contact area between the elliptical plate 603 and the filter screen during rotation, reducing the situation that the elliptical plate 603 rotates unstably or vibrates due to the large contact area between the elliptical plate 603 and the filter plate, thereby further improving the cleaning effect of the filter screen.
