[0020] Furthermore, an exhaust port is provided on the other side of the sand prevention bin, and an exhaust fan is installed in the exhaust port.

[0021] Beneficial effects of the present invention:

[0022] 1. By providing a diversion mechanism and utilizing the interaction of multiple sets of swing plates in the diversion mechanism, when the external wind force increases, the airflow can contact one side of the arc-shaped design of the swing plate, thereby controlling the multiple sets of swing plates to rotate inward with the first shaft as the center, causing the rubber sheet to deform, thereby controlling the flow area of ​​the inner circular channel and the outer circular channel to change, thereby playing a role in diverting the airflow, so that the inner circular channel and the outer circular channel can adaptively adjust the flow area of ​​the channel according to the wind force, thereby optimizing the airflow path, reducing turbulence and eddy currents, and improving the uniformity and stability of the airflow. In addition, through diversion, the pressure loss of a single set of channels can also be reduced. After the airflow is dispersed into multiple sets of channels, the airflow speed of each set of channels can be more stable, thereby reducing the overall pressure loss and avoiding the problem that when the external wind force increases, the resistance to air flow also increases, resulting in the filter being unable to effectively block more sand and dust.

[0023] 2. By providing a sand filtering mechanism and an abutment portion, after the airflow passes through the diversion mechanism in the air inlet pipe, it enters the channel formed by the fixed plate, the vertical plate and the side plate assembly for multiple filtrations. The airflow can not only be filtered through the first filter plate and the second filter plate, but can also be finally filtered again through the second sand filter plate. When the external wind force increases, the impeller can rotate and control the top plate to perform reciprocating motion, so that the first filter plate and the second filter plate contact and vibrate. The vibration of the first filter plate and the second filter plate can help remove sand and dust attached to the first filter plate and the second filter plate, thereby reducing blockage and maintaining filtration efficiency, while achieving adaptive cleaning after the wind force increases.

[0024] 3. By setting up a sand discharge mechanism, when the first filter plate and the second filter plate vibrate to remove sand and dust, the sand and dust can fall downward due to the gravity of the sand and dust, and then fall onto the surface of the inclined block. As the sand and dust accumulate more and more, the door panel is controlled to flip under the gravity of the sand and dust, so that the sand and dust can be automatically discharged to the outside of the sand control bin through the sand discharge port.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] Reference Figure 1-7An electrical integrated power distribution control cabinet comprises a cabinet body 1, a base 2 is fixed at the bottom end of the cabinet body 1, a sand-proof bin 3 is fixed on the top of the base 2, and a cover of the sand-proof bin 3 is arranged outside the cabinet body 1, wherein a cooling chamber 4 is opened in the sand-proof bin 3, and an air inlet is opened on one side of the sand-proof bin 3, an air inlet pipe 5 is fixedly installed in the air inlet, and the air outlet end of the air inlet pipe 5 passes through the cooling chamber 4, and a first sand filter plate 6 is fixedly installed at the air inlet end of the air inlet pipe 5, and the first sand filter plate 6 is used for preliminary filtering of the airflow, and a second sand filter plate 7 is provided on one side of the cooling chamber 4, and the second sand filter plate 7 is fixed between the inner wall of the cooling chamber 4 and the outer wall of the cabinet body 1, and the second sand filter plate 7 is used for filtering the airflow passing through one side of the cooling chamber 4 again.

[0042] The air inlet pipe 5 is provided with a diversion mechanism, which includes a plurality of swing plates 11, which are designed in a circular ring shape, and the plurality of swing plates 11 are rotatably connected to the air inlet pipe 5 through a first shaft 12, wherein the swing plates 11 rotate around the first shaft 12, and there is a certain rotation gap between each two sets of swing plates 11, and the two ends of each set of the first shaft 12 are respectively rotatably connected to a bracket 13 through a bearing, and the other end of each set of the bracket 13 is fixed to the inner wall of the air inlet pipe 5, and each set of the first shaft Both ends of the rod 12 are wound with a first torsion spring 14, and the two ends of each group of first torsion springs 14 are respectively welded between the corresponding swing plate 11 and the bracket 13, and a rubber sheet 15 is fixed between the inner sides of the multiple groups of swing plates 11, and the head and tail ends of the rubber sheet 15 are connected to form a group of inner circular channels, and a group of outer circular channels is formed between the outer sides of the multiple groups of swing plates 11 and the inner wall of the air inlet pipe 5, and the multiple groups of brackets 13 divide the outer circular channels into several groups of flow areas to divert the air through the inner circular channels and the outer circular channels.

[0043] Specifically, one side of the swing plate 11 close to the inner wall of the air inlet pipe 5 is designed in an arc shape, and one side of the swing plate 11 close to the rubber sheet 15 is designed in a relatively gentle manner. When the wind force is in a stable state, the swing plate 11 can rotate outward with the first shaft rod 12 as the center under the torsion control of the first torsion spring 14. At this time, the inner circular channel formed by the rubber sheet 15 is the main air inlet channel. When the external wind force increases, the airflow enters through the air inlet pipe 5 and contacts the front end of the swing plate 11. As the airflow continues to flow in, the airflow contacts one side of the swing plate 11 with a circular arc shape, thereby controlling multiple groups of swing plates 11 to rotate inward with the first shaft rod 12 as the center, causing the rubber sheet 15 to deform, thereby controlling the flow area of ​​the inner circular channel and the outer circular channel to change. The cooperation of the above-mentioned structure can play a role in diverting the airflow when the external wind force increases, so that the inner circular channel and the outer circular channel can adapt to the changes in wind force and automatically adjust the distribution of the airflow.

[0044] Reference Figure 1-4 and Figure 8-11A sand filter mechanism is provided on one side of the cooling chamber 4, and the sand filter mechanism includes a fixed plate 21, a vertical plate 22 and a side plate assembly 23. The fixed plate 21 is provided with two groups, and the two groups of fixed plates 21 are respectively fixed at the front and rear of one side of the cooling chamber 4, and the two groups of fixed plates 21 are both located below the second sand filter plate 7. The vertical plate 22 is fixed on one side between the two groups of fixed plates 21, and the air outlet end of the air inlet pipe 5 passes through the vertical plate 22. The side plate assembly 23 includes a bottom plate 231, a silicone plate 232 and a top plate 233. The bottom plate 231 is fixed on the other side between the two groups of fixed plates 21, and the top plate 233 is slidably connected between the two groups of fixed plates 21. On the other side of the room, the bottom plate 231 and the top plate 233 are connected by a silicone plate 232, and a plurality of groups of first filter plates 24 are fixed to the side of the vertical plate 22 close to the top plate 233, and a plurality of groups of second filter plates 25 are fixed to the side of the top plate 233 close to the vertical plate 22, and the plurality of groups of first filter plates 24 and second filter plates 25 are all designed to be tilted downward, wherein the two opposite groups of first filter plates 24 and second filter plates 25 are designed to be staggered up and down, and the airflow enters the channel formed by the fixed plate 21, the vertical plate 22 and the side plate assembly 23 through the air inlet pipe 5, and contacts with the first filter plates 24 and the second filter plates 25 to achieve filtration.

[0045] Specifically, an abutment portion is provided on the side of the top plate 233 away from the vertical plate 22, and the abutment portion is used to control the top plate 233 to perform reciprocating motion to shake off the filtered dust, and the abutment portion includes an abutment wing 31, and the abutment wing 31 is provided with four groups, and the four groups of abutment wings 31 are evenly distributed at the four corners of the top plate 233 away from the vertical plate 22. Every two groups of horizontally arranged abutment wings 31 are rotatably connected between the two groups of fixed plates 21 through a second shaft rod 32, and both ends of the second shaft rod 32 are wound with a second torsion spring 36, and the two ends of the second torsion spring 36 are respectively welded between the abutment wing 31 and the fixed plate 21, wherein each group of abutment wings 31 is movably in contact with a cam 33 on the side away from the vertical plate 22, and every two groups of horizontally arranged cams 33 are connected through a third shaft rod 34 is rotatably connected between the two groups of fixed plates 21, wherein one end of the third shaft rod 34 passes through the outside of the sand prevention bin 3 and is fixed with an impeller 35. When the wind force increases, the impeller 35 can be controlled to rotate so that the cam 33 abuts against the abutting wing 31, and the abutting wing 31 is controlled to flip around the second shaft rod 32, and then abuts against the top plate 233 for reciprocating motion. During the reciprocating motion of the top plate 233, the second filter plate 25 can be driven to contact the corresponding first filter plate 24, so that the first filter plate 24 and the second filter plate 25 vibrate. The vibration of the first filter plate 24 and the second filter plate 25 can help remove sand and dust attached to the first filter plate 24 and the second filter plate 25, thereby reducing blockage and maintaining filtration efficiency, thereby achieving adaptive cleaning after the wind force increases.

[0046] It is worth mentioning that the limiting rods 26 are symmetrically fixed on the adjacent sides of the two sets of fixing plates 21, and the inner walls on the front and rear sides of the top plate 233 are provided with limiting grooves 27 adapted to the limiting rods 26. The limiting grooves 27 are limitedly engaged outside the limiting rods 26. Through the cooperation of the limiting rods 26 and the limiting grooves 27, the top plate 233 can be limited.

[0047] Through the cooperation of the above-mentioned structure, the airflow entering one side of the cooling chamber 4 can be filtered multiple times. The airflow can not only be filtered through the first filter plate 24 and the second filter plate 25, but can also be finally filtered again through the second sand filter plate 7, and can make the first filter plate 24 and the second filter plate 25 vibrate by controlling the reciprocating motion of the top plate 233. The vibration of the first filter plate 24 and the second filter plate 25 can prevent the accumulation of sand and dust, thereby improving the filtering efficiency, and at the same time realizes adaptive cleaning after the wind force increases.

[0048] During use: when the external wind force increases, the airflow first enters the air inlet pipe 5 and contacts the front end of the swing plate 11. As the airflow continues to flow in, the airflow contacts one side of the arc-shaped design of the swing plate 11. At this time, the swing plate 11 rotates inward with the first shaft rod 12 as the center under the action of the airflow pressure, causing the rubber sheet 15 to deform, thereby controlling the flow area of ​​the inner circular channel and the outer circular channel to change, thereby achieving the effect of airflow diversion. The diverted gas can stably enter the channel composed of the fixed plate 21, the vertical plate 22 and the side plate assembly 23, and contact the first filter plate 24 and the second filter plate 25 for filtration. The airflow after contacting the first filter plate 24 and the second filter plate 25 will be filtered again through the second sand filter plate 7, further improving the filtering effect;

[0049] At the same time, when the external wind force increases, the impeller 35 will be controlled to rotate. At this time, the impeller 35 controls the third shaft rod 34 and the cam 33 to rotate. The rotation of the cam 33 abuts the abutting wing 31, causing the abutting wing 31 to flip around the second shaft rod 32, thereby controlling the abutting wing 31 to abut the top plate 233, causing the top plate 233 to reciprocate. At this time, the silicone plate 232 is deformed, and the reciprocating motion of the top plate 233 drives the second filter plate 25 to contact the corresponding first filter plate 24 back and forth, causing the first filter plate 24 and the second filter plate 25 to vibrate, thereby removing the sand and dust attached to the first filter plate 24 and the second filter plate 25, causing the sand and dust to fall downward under the action of gravity.

[0050] Reference Fig.12A sand discharge mechanism is provided at the lower side of the cooling chamber 4, and the sand discharge mechanism includes an inclined block 41 fixed in the cooling chamber 4, and a sand discharge port is provided at the lower side of the sand prevention bin 3. A door panel 42 is rotatably connected to the sand discharge port through a fourth shaft rod 43, and the bottom of the door panel 42 abuts against one side of the inclined block 41. Both ends of the fourth shaft rod 43 are wound with a third torsion spring 44, and the two ends of the third torsion spring 44 are respectively welded between the sand discharge port and the door panel 42. When the sand and dust fall under the vibration of the first filter plate 24 and the second filter plate 25, it can fall onto the surface of the inclined block 41. As more and more sand and dust accumulate, the door panel 42 is flipped under the pressure of gravity. At this time, the sand and dust can be discharged to the outside of the sand prevention bin 3 through the sand discharge port. By utilizing the torsion of the third torsion spring 44, the door panel 42 can be controlled to reset again after the sand and dust are removed, and then abut against the inclined block 41 again.

[0051] Reference Fig.13 The cabinet 1 is provided with a heat dissipation mechanism, which includes a first heat dissipation plate 51, a second heat dissipation plate 52 and a third heat dissipation plate 53. The first heat dissipation plate 51 is fixedly attached to the upper side of the cabinet 1, the second heat dissipation plate 52 is fixedly attached to the top of the cabinet 1, and the third heat dissipation plate 53 is fixedly attached to the other side of the cabinet 1. The first heat dissipation plate 51, the second heat dissipation plate 52 and the third heat dissipation plate 53 are fixed to each other, and a plurality of baffles 54 are also fixed on the first heat dissipation plate 51, the second heat dissipation plate 52 and the third heat dissipation plate 53. The material of the first heat dissipation plate 51, the second heat dissipation plate 52, the third heat dissipation plate 53 and the baffles 54 can be copper or aluminum, but is not limited to this embodiment. The baffles 54 between each two adjacent groups are fixed. A group of heat dissipation channels are formed, and multiple groups of heat dissipation grooves 55 for heat dissipation are opened on the top of the cabinet 1. An exhaust port is opened on the other side of the sand-proof bin 3, and an exhaust fan 8 is installed in the exhaust port. The airflow filtered by the second sand filter plate 7 can flow in the heat dissipation channel, and because the first heat dissipation plate 51, the second heat dissipation plate 52 and the third heat dissipation plate 53 are all fixedly fitted with the cabinet 1, the heat generated by the electrical components in the cabinet 1 can be dissipated during the flow of the airflow, and when the airflow passes over the cabinet 1, the heat accumulated on the top of the cabinet 1 can be quickly taken away under the action of the heat dissipation grooves 55, and as the exhaust fan 8 continuously discharges air outward, the heat is discharged to the outside of the sand-proof bin 3 through the exhaust fan 8.
