Through the application of advanced sensing and measurement technologies, advanced equipment technologies, advanced control methods, and advanced decision support system technologies, the goals of reliable, safe, economic, efficient, environmentally friendly, and safe-to-use power grids are achieved. When constructing a smart grid, a heat-dissipating distribution cabinet needs to be installed to provide a location and protection for the installation of electrical components, as well as ventilate and dissipate heat from the electrical components.

[0003] However, in practical applications, there are still some problems that have not been solved. The following are some common problems of the heat-dissipating distribution cabinet based on a smart grid: In the prior art, the rotation speed and air intake volume of the cooling fan cannot be adjusted according to the heat inside the distribution cabinet, which will lead to poor heat dissipation effect of the distribution cabinet, continuous increase of the internal temperature, and may cause equipment failures and safety hazards. In addition, it is not convenient to clean the filter plate used at the air intake. Since the fan is always running, the fine dust generated during the cleaning process will enter the distribution cabinet under the suction of the fan, affecting the electrical components inside the distribution cabinet.

Detailed implementation manners

[0034] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the drawings of the specification.

[0035] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0036] Second, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively mutually exclusive embodiment with other embodiments. Embodiment 1

[0037] Refer to Figures 1 to 7 , which is the first embodiment of the present invention. This embodiment provides a heat-dissipating power distribution cabinet based on a smart grid. The heat-dissipating power distribution cabinet based on the smart grid includes a power distribution cabinet mechanism 100, an air inlet filtering mechanism 200, and a plugging and slag discharging mechanism 300. The air inlet filtering mechanism 200 can filter the gas entering the power distribution cabinet, and the plugging and slag discharging mechanism 300 can adjust the rotation speed and air intake volume of the cooling fan according to the heat in the power distribution cabinet, facilitating the cleaning of the filter plate used at the air inlet.

[0038] Specifically, the power distribution cabinet mechanism 100 includes a cabinet body 101, a cabinet door 102, an air outlet plate 103, a frame body 104, and a fan 105. The cabinet door 102 is rotatably connected to the surface of the cabinet body 101. The air outlet plate 103 is installed on the surface of the cabinet body 101 and is located on one side thereof. The frame body 104 is connected to the surface of the cabinet body 101 and is located on the other side thereof. The fan 105 is fixedly connected to the inner wall of the frame body 104.

[0039] The cabinet door 102 is rotatably connected to the surface of the cabinet body 101 through a hinge. The air outlet plate 103 is fixedly connected to the surface of the cabinet body 101 by screws, and through holes are provided on its surface, thus facilitating exhaust heat dissipation. The fan 105 is fixedly connected to the inner wall of the frame body 104 by bolts. Through the operation of the fan 105, the outside gas is transmitted into the cabinet body 101 and then discharged from the air outlet plate 103, enabling the air inside the power distribution cabinet to flow and improving the heat dissipation effect.

[0040] Specifically, the air inlet filtering mechanism 200 is installed on the surface of the frame body 104 and includes a cylinder body 201, an elbow pipe 202, an air inlet hood 203, a housing 204, a round block 205, a cylinder 206, a filter net plate 207, a cleaning brush 208, a transparent window 209, and an air outlet hole 210. The cylinder body 201 is connected to the surface of the frame body 104. Both ends of the elbow pipe 202 are respectively connected to the air inlet hood 203 and the cylinder body 201. The housing 204 is fixedly connected to the inner wall of the cylinder body 201. The round block 205 is fixedly connected to the surface of the housing 204. The cylinder 206 is rotatably connected to the surfaces of the elbow pipe 202 and the round block 205. The filter net plate 207 is movably connected to the surface of the housing 204. The cleaning brush 208 is fixedly connected to the surface of the cylinder 206. The transparent window 209 is fixedly connected to the surface of the cylinder body 201. The air outlet hole 210 is provided on the surface of the cylinder 206.

[0041] The two ends of the curved pipe 202 are fixedly connected to the air intake hood 203 and the surface of the cylinder 201 respectively to avoid air leakage through the gap during the air intake process. The cylinder 206 is rotatably sleeved on one end of the curved pipe 202 through a sealed bearing. The curved pipe 202 keeps the air intake hood 203 and the cylinder 206 connected, so that the air entering the air intake hood 203 enters the cylinder 206 through the curved pipe 202, and then is discharged from the air outlet 210 into the shell 204. The gas entering the shell 204 and then discharged is filtered by the filter plate 207, and then passes through the frame 104 into the cabinet 101 for ventilation and heat dissipation.

[0042] The cleaning brush 208 is fixedly connected to the surface of the cylinder 206 by a support rod. When the cylinder 206 rotates and drives the cleaning brush 208 to rotate, the dust attached to the surface of the filter plate 207 can be cleaned. A sealing sleeve is provided between the cylinder 206 and the round block 205, and does not affect the relative rotation between them. There are several air outlet holes 210, so that the gas entering the cylinder 206 can be discharged from multiple directions. The transparent window 209 makes it easy to observe whether the filter plate 207 is in the installation position.

[0043] Specifically, the blocking and slag discharge mechanism 300 is installed on the surface of the air inlet filtering mechanism 200, the frame 104 and the air outlet plate 103, and includes an adjusting member 301, a switch 302, a touch member 303, a driving member 304, an air inlet adjusting member 305, a shielding member 306 and a fixing member 307. The adjusting member 301 and the switch 302 are installed on the surface of the air outlet plate 103, the touch member 303 is arranged on the surface of the bend 202 and the cylinder 206, the driving member 304 is arranged on the surface of the cylinder 206 and the shielding member 306, the air inlet adjusting member 305 is arranged on the surface of the air inlet cover 203 and the shielding member 306, the shielding member 306 is arranged on the surface of the frame 104 and the driving member 304, and the fixing member 307 is installed on the surface of the shell 204 and the round block 205.

[0044] The resistance value in the access circuit is adjusted by adjusting the adjustment member 301, and the on / off state and current of the series circuit are controlled by temperature, thereby controlling the repulsive force generated by the electromagnet 303b and the power of the fan 105. The resistor 301a, the conductive ring 301d, the fan 105, the electromagnet 303b and the switch 302 are connected in series in a circuit. The entire circuit can be directly shut down by the switch 302 during maintenance. The on / off state of the series circuit and the total resistance value in the access circuit can be controlled by the position of the conductive ring 301d on the resistor 301a. Under the same constant voltage, the current in the circuit can be changed, thereby controlling the repulsive force generated by the electromagnet 303b and the power of the fan 105.

[0045] It is triggered by the touch member 303 according to the different repulsive forces generated by the electromagnet 303b being energized. Then, under the operation of the driving member 304, the adjustment of the air inlet adjustment member 305 is realized, and the function of adjusting the size of the air inlet according to the temperature inside the cabinet body 101 is achieved. When the power is off at a relatively low temperature, the driving member 304 can drive the cylinder 206 and the cleaning brush 208 to rotate, and the circular plate 304b can move away from the cylinder body 201 to clean the filter screen plate 207 and facilitate the discharge of the cleaned dust.

[0046] After the power is off and before cleaning, the blocking member 306 blocks the frame body 104 to prevent dust during the cleaning process from being sucked into the cabinet body 101 due to the inertial rotation of the fan blades. And when the fan 105 runs instantaneously after being powered on, air will not enter through the exposed end of the cylinder body 201. When the circular plate 304b contacts the cylinder body 201, the blocking member 306 will no longer block the frame body 104, and normal air intake through the air intake cover 203 can be realized. Embodiment 2

[0047] Refer to Figures 4 to 12 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment.

[0048] Specifically, the adjusting member 301 includes a resistor 301a, a circular shell 301b, a sliding rod 301c, a conductive ring 301d, a piston 301e, a metal liquid 301f, a first spring 301g, and a heat conduction rod 301h. The resistor 301a and the circular shell 301b are installed on the surface of the air outlet plate 103. The sliding rod 301c is slidably connected to the surface of the circular shell 301b. The conductive ring 301d is fixedly connected to one end of the sliding rod 301c and sleeved on the surface of the resistor 301a. The piston 301e is fixedly connected to the other end of the sliding rod 301c and contacts the inner wall of the circular shell 301b. The metal liquid 301f is filled in the inner cavity of the circular shell 301b. The first spring 301g is sleeved on the surface of the sliding rod 301c, and its two ends are respectively fixedly connected to the surfaces of the circular shell 301b and the piston 301e. The heat conduction rod 301h is fixedly connected to the surface of the circular shell 301b.

[0049] The resistor 301a is fixedly connected to the surface of the air outlet plate 103 through an insulating plate. The resistor 301a and the conductive ring 301d form a sliding rheostat, which is a prior art and will not be elaborated here. The sliding rod 301c penetrates through the circular shell 301b and is slidably connected to it. The metal liquid 301f is mercury or a heat-sensitive substance similar to mercury, such as gallium and its alloys. Under the action of heat expansion, it can push the piston 301e to move, and then the sliding rod 301c can push the conductive ring 301d to move on the surface of the resistor 301a, changing the magnitude of the current in the series circuit.

[0050] When the temperature drops, the molten metal 301f contracts due to cooling. Under the action of the first spring 301g during its rebound, the piston 301e, the sliding rod 301c, and the conductive ring 301d move back, increasing the total resistance value in the circuit. Even when the temperature is relatively low, the power is cut off, causing the fan 105 to stop running and saving electricity. Heat dissipation requirements can be completed through natural ventilation. The number of heat conduction rods 301h is several, and they are all fixedly connected to the surface of the circular shell 301b. Through the heat conduction rods 301h for heat exchange, the molten metal 301f can be heated or cooled according to the temperature of the gas inside the cabinet 101, realizing the adjustment of the resistance value in the series circuit according to the temperature change.

[0051] The touch part 303 includes a hollow rod 303a, an electromagnet 303b, a housing part 303c, a first contactor 303d, a second contactor 303e, and a force applying part 303f. The hollow rod 303a is fixedly connected to the surface of the bent pipe 202. The cylinder 206 is rotatably connected to the surface of the hollow rod 303a. The electromagnet 303b is fixedly connected to one end of the hollow rod 303a. The housing part 303c is fixedly connected to the surface of the electromagnet 303b. The first contactor 303d and the second contactor 303e are fixedly connected to the inner wall of the housing part 303c. The force applying part 303f is installed on the surface of the housing part 303c.

[0052] The cylinder 206 is rotatably connected to the surface of the hollow rod 303a through a sealed bearing. The housing part 303c is fixedly connected to the surface of the electromagnet 303b through a support rod. The first contactor 303d and the second contactor 303e are connected to the motor 304e through a relay. Controlling the operation of the motor 304e and the number of rotations of the output shaft through the relay is prior art and will not be elaborated here. By the magnitude of the repulsive force generated when the electromagnet 303b is energized, the force applying part 303f is acted on, thereby achieving the actuation of the first contactor 303d and the second contactor 303e at different stages.

[0053] The driving part 304 includes a square rod 304a, a circular plate 304b, a connecting plate 304c, a second spring 304d, a motor 304e, a reciprocating roller 304f, a moving block 304g, and a short column 304h. The square rod 304a is slidably connected to the surface of the circular block 205. The circular plate 304b is sleeved on the surface of the square rod 304a and contacts the surface of the cylinder body 201. The connecting plate 304c is fixedly connected to one end of the square rod 304a. The second spring 304d is sleeved on the surface of the square rod 304a, and its two ends respectively contact the surfaces of the connecting plate 304c and the circular plate 304b. The motor 304e is fixedly connected to the inner wall of the circular block 205. One end of the reciprocating roller 304f is fixedly connected to the output shaft of the motor 304e. The other end of the reciprocating roller 304f is rotatably connected to the surface of the housing part 303c. The moving block 304g is fixedly connected to the other end of the square rod 304a and is sleeved on the surface of the reciprocating roller 304f. The short column 304h is fixedly connected to the surface of the moving block 304g and cooperates with the reciprocating roller 304f.

[0054] The square rod 304a passes through the round block 205 and is slidably connected to it and is sealed. A reciprocating groove that is compatible with the short column 304h is provided on the surface of the reciprocating roller 304f. The reciprocating roller 304f is driven to rotate by the motor 304e, and the short column 304h is moved under the guidance of the square rod 304a, thereby driving the moving block 304g and the square rod 304a to move.

[0055] Under the action of the second spring 304d and the pressure exerted by the connecting plate 304c, the circular plate 304b is brought into close contact with the surface of the cylinder 201 under the action of the elastic force of the second spring 304d. At the same time, the connecting plate 304c can be driven to move without being hindered by the movement of the square rod 304a. The reciprocating roller 304f is rotatably connected to the surface of the shell 303c through the bearing, so that the reciprocating roller 304f and the shell 303c are indirectly connected, thereby improving the stability during rotation.

[0056] The driving member 304 also includes a guide column 304i, a guide groove 304j, a short block 304k and a stop block 304L. The guide column 304i is fixedly connected to the top of the moving block 304g. The guide groove 304j is opened on the inner wall of the cylinder 206 and cooperates with the guide column 304i. The guide column 304i is slidably connected in the guide groove 304j. The short block 304k is fixedly connected to the bottom of the square rod 304a. The stop block 304L is fixedly connected to the top of the square rod 304a.

[0057] The guide groove 304j is divided into two parts. The first part is the guide column 304i, which will not cause the cylinder 206 to rotate when it moves. The second part is the guide column 304i, which can cause the cylinder 206 to rotate when it moves, thereby causing the cleaning brush 208 to rotate to clean the surface of the filter plate 207. When adjusting the size of the air inlet and closing the shielding member 306, the guide column 304i moves in the first part, and the cleaning brush 208 rotates to clean the filter plate 207.

[0058] The guide column 304i moves in the second part. When the filter screen 207 is cleaned by the short block 304k, the short block 304k moves outward with the square rod 304a to push the circular plate 304b to move, so that the circular plate 304b is separated from the cylinder 201, and then one end of the shell 204 is exposed, which is convenient for discharging the cleaned dust. The block 304L moves outward with the square rod 304a to act on the fixing part 307, so that the fixing part 307 loses the limiting fixation on the filter screen 207, which is convenient for removing the filter screen 207 for deep cleaning or replacement.

[0059] The shielding member 306 includes a vertical plate 306a, a connecting rod 306b, a short rod 306c and a guide frame 306d. The vertical plate 306a is slidably connected to the surface of the frame body 104, the connecting rod 306b is fixedly connected to the surface of the connecting plate 304c, the short rod 306c is fixedly connected to the surface of the vertical plate 306a, and the guide frame 306d is sleeved on the surface of the short rod 306c and fixedly connected to the surface of the connecting rod 306b.

[0060] The vertical plate 306a passes through the frame 104 and is slidably connected to it and is sealed. The guide frame 306d is divided into three parts. The short rod 306c moves in the upper part without moving the vertical plate 306a. At this time, it is not affected when the air inlet adjustment member 305 is adjusted. The short rod 306c moves in the middle part to move the vertical plate 306a. At this time, it is to make advance preparations for cleaning the filter plate 207, or after the fan 105 is turned on, the circular plate 304b is brought into contact with the cylinder 201 to release the blockage of the frame 104 and achieve normal ventilation and heat dissipation. The short rod 306c moves in the lower part without moving the vertical plate 306a. At this time, during the cleaning process, the connecting plate 304c drives the connecting rod 306b and the guide frame 306d to move without being affected. Example 3

[0061] Reference Figures 6 to 15 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0062] Specifically, the air inlet adjustment member 305 includes a rotating rod 305a, a blade 305b, a gear 305c, a tooth plate 305d, a connecting block 305e, a movable plate 305f, a sleeve 305g and a torsion spring 305h. The rotating rod 305a is rotatably connected to the surface of the air inlet cover 203, the blade 305b is sleeved on the surface of the rotating rod 305a, the gear 305c is fixedly connected to one end of the rotating rod 305a, the tooth plate 305d is fixedly connected to the surface of the connecting rod 306b and meshes with the gear 305c, the connecting block 305e is fixedly connected to the other end of the rotating rod 305a, the movable plate 305f is rotatably connected to the surface of the connecting block 305e, the sleeve 305g is sleeved on the surface of the rotating rod 305a and fixedly connected to the surface of the air inlet cover 203, and the torsion spring 305h is sleeved on the surface of the rotating rod 305a, and its two ends are respectively fixedly connected to the sleeve 305g and the surface of the rotating rod 305a.

[0063] The number of rotating rods 305a and blades 305b is the same. The rotating rods 305a are rotatably connected to the surface of the air intake cover 203 through bearings, and the blades 305b are fixedly connected to the surface of the rotating rods 305a. The adjacent connecting blocks 305e are indirectly connected through movable plates 305f, so that when one rotating rod 305a rotates, it can drive multiple rotating rods 305a to rotate, thereby causing multiple blades 305b to rotate.

[0064] The movement of the toothed plate 305d can drive the gear 305c to rotate, thereby causing the rotating rod 305a to rotate, realizing the adjustment of the angle of the blade 305b, adjusting the size of the incoming air. Under the action of its torsion force, the torsion spring 305h makes the rotating rod 305a more stable during rotation, and at the same time provides power for the rotation reset of the rotating rod 305a and the blade 305b.

[0065] The fixing member 307 includes a groove 307a, a clamping plate 307b, a third spring 307c and a resisting rod 307d. The groove 307a is formed in the housing 204. The clamping plate 307b is slidably connected in the groove 307a. The third spring 307c is sleeved on the surface of the clamping plate 307b, and its two ends are respectively fixedly connected to the inner wall of the groove 307a and the surface of the clamping plate 307b. The resisting rod 307d is slidably connected to the surfaces of the housing 204 and the round block 205 and contacts the surface of the clamping plate 307b. A clamping groove is formed on the surface of the filter mesh plate 207. One end of the clamping plate 307b penetrates through the housing 204 and extends into the inner cavity of the clamping groove and contacts its inner wall.

[0066] One end of the clamping plate 307b inserted into the clamping groove is chamfered, which is convenient for the filter mesh plate 207 to squeeze the clamping plate 307b to move it when installing the filter mesh plate 207, thereby compressing the third spring 307c. When one end of the clamping plate 307b is aligned with the clamping groove, under the action of the elastic force of the third spring 307c, the clamping plate 307b is inserted into the clamping groove. By moving the square rod 304a outwards to drive the abutting block 304L to move and contact the resisting rod 307d, squeezing it upwards, and then squeezing and pushing the clamping plate 307b to move, so that one end of the clamping plate 307b disengages from the clamping groove, losing the limit on the filter mesh plate 207, which is convenient for removing the filter mesh plate 207 for in-depth cleaning or replacement.

[0067] The force-applying member 303f includes a first connecting rod 303f-1, a first iron block 303f-2, a first pressing block 303f-3, a fourth spring 303f-4, a connecting plate 303f-5, a second connecting rod 303f-6, a second iron block 303f-7, a second pressing block 303f-8 and a fifth spring 303f-9. The first connecting rod 303f-1 is slidably connected to the surface of the housing member 303c. The first iron block 303f-2 and the first pressing block 303f-3 are respectively and fixedly connected to both ends of the first connecting rod 303f-1. The fourth spring 303f-4 is sleeved on the surface of the first connecting rod 303f-1, and its two ends are respectively and fixedly connected to the inner wall of the housing member 303c and the surface of the first pressing block 303f-3. The connecting plate 303f-5 is fixedly connected to the surface of the first connecting rod 303f-1. The second connecting rod 303f-6 is slidably connected to the surface of the connecting plate 303f-5. The second iron block 303f-7 and the second pressing block 303f-8 are respectively and fixedly connected to both ends of the second connecting rod 303f-6. The fifth spring 303f-9 is sleeved on the surface of the second connecting rod 303f-6, and its two ends are respectively and fixedly connected to the connecting plate 303f-5 and the second pressing block 303f-8.

[0068] The first connecting rod 303f-1 penetrates through the housing member 303c and is slidably connected thereto. When the conductive ring 301d just accesses the circuit, the repulsive force generated by the electromagnet 303b pushes the first iron block 303f-2, the first connecting rod 303f-1, the first pressing block 303f-3, the second connecting rod 303f-6, the second iron block 303f-7, the fifth spring 303f-9, the second pressing block 303f-8 and the connecting plate 303f-5 to move, so that the fourth spring 303f-4 is stretched to contact the first pressing block 303f-3 with the first contactor 303d, and the operation of the first state is carried out, so that the blade 305b is opened by 45 degrees.

[0069] When the conductive ring 301d moves to the extreme end of the resistor 301a, the current of the circuit is the largest at this time, and it continues to push the second iron block 303f-7, the second connecting rod 303f-6 and the second pressing block 303f-8 to move, so that the fifth spring 303f-9 is stretched, and the second pressing block 303f-8 is contacted with the second contactor 303e, and the operation of the second state is carried out, so that the blade 305b is opened by 90 degrees to achieve the maximum air intake.

[0070] A cover body 106 is sleeved on the surface of the cylinder body 201. The cover body 106 is fixedly connected to the surface of the cabinet body 101. A baffle 107 is fixedly connected to the top of the cover body 106. A rain shield 108 is fixedly connected to the top of the cabinet body 101.

[0071] The cylinder body 201 and some structures are shielded by the cover body 106 to avoid exposure. The top of the air intake cover 203 is shielded by the baffle 107 to prevent the entry of sundries and rainwater. The cabinet body 101 is shielded from water by the rain shield 108 in rainy and snowy weather.

[0072] A first guide plate is sleeved on the surface of the tooth plate 305d. The first guide plate is fixedly connected to the air inlet cover 203. The tooth plate 305d is guided and supported by the first guide plate, making it more stable when moving. A second guide plate is sleeved on the surface of the connecting rod 306b. The second guide plate is fixedly connected to the frame body 104. The connecting rod 306b is guided and supported by the second guide plate, making it more stable when moving.

[0073] A positioning rod is fixedly connected to the surface of the housing 204. Positioning holes are formed on the surface of the filter net plate 207. The positioning rod is inserted into the positioning holes. The filter net plate 207 can be preliminarily and accurately positioned on the housing 204 through the positioning rod and the positioning holes, facilitating subsequent fixing by the fixing member 307.

[0074] When in use, the present invention has three working states. In the first working state, the heat in the cabinet 101 conducts heat through the heat conducting rod 301h to expand the metal liquid 301f, so that when the conductive ring 301d contacts the resistor 301a, the leaf plate 305b opens at 45 degrees and the fan 105 operates. At this time, it is a closed circuit. When the metal liquid 301f expands to push the piston 301e to move, the sliding rod 301c and the conductive ring 301d move accordingly, and the first spring 301g is compressed. The electromagnet 303b is energized to generate a repulsive force to push the force applying member 303f to move. Except for the fourth spring 303f-4, the fourth spring 303f-4 is stretched at this time, and the first pressing block 303f-3 on the force applying member 303f contacts the first contactor 303d.

[0075] Under the action of the relay, the output shaft of the motor 304e drives the reciprocating roller 304f to rotate forward for a certain number of turns and stop. Then, the short column 304h drives the guide post 304i, the square rod 304a, the connecting plate 304c, the connecting rod 306b, the tooth plate 305d and the guide frame 306d to move. At this time, the guide post 304i moves within the first part of the guide groove 304j, and the cylinder 206 will not rotate. And the short rod 306c moves on the upper part of the guide frame 306d, and the vertical plate 306a will not move. The movement of the tooth plate 305d drives the gear 305c and the rotating rod 305a connected to the gear 305c to rotate. Under the action of the connecting block 305e and the movable plate 305f, multiple rotating rods 305a and leaf plates 305b rotate, and the torsion spring 305h deforms, realizing the 45-degree opening of the leaf plate 305b for air intake.

[0076] The second working state is when the heat inside the cabinet body 101 is relatively high. Through heat conduction by the heat conduction rod 301h, the metal liquid 301f expands, causing the conductive ring 301d to move to the outermost end of the resistor 301a. At this time, the leaf plate 305b opens by 90 degrees and the fan 105 runs at high speed. As the conductive ring 301d moves, the resistance value connected to the circuit gradually decreases. At this time, the current continuously increases, increasing the rotation speed of the fan 105 blades. When the current reaches a value that causes the repulsive force generated by the electromagnet 303b to push the second iron block 303f - 7, the second connecting rod 303f - 6, and the second pressing block 303f - 8 to move. At this time, the fifth spring 303f - 9 is stretched, and when the second pressing block 303f - 8 contacts the second contactor 303e.

[0077] Under the action of the relay, the output shaft of the motor 304e drives the reciprocating roller 304f to rotate forward by a certain number of turns and then stop. The operating principle of the corresponding structure in the first state is the same, realizing that the leaf plate 305b opens by 90 degrees for air intake, increasing the air intake volume and heat dissipation efficiency, and adjusting the rotation speed of the fan 105 and the air intake size according to the heat inside the power distribution cabinet.

[0078] The third working state is when the temperature inside the cabinet body 101 is relatively low. The metal liquid 301f contracts due to cooling, and under the action of the first spring 301g rebounding, the conductive ring 301d disengages from the resistor 301a to cut off the power supply, causing the fan 105 to stop running to save electricity. At this time, the filter screen plate 207 is cleaned and dust is discharged. After the power is cut off, the electromagnet 303b does not generate a repulsive force. Under the action of the fourth spring 303f - 4 and the fifth spring 303f - 9, the first pressing block 303f - 3 disengages from the first contactor 303d, and the second pressing block 303f - 8 disengages from the second contactor 303e.

[0079] Under the action of the relay, the output shaft of the motor 304e drives the reciprocating roller 304f to rotate backward by a certain number of turns and then stop. During this process, first, the toothed plate 305d, the gear 305c, the rotating rod 305a, and the leaf plate 305b are reset, and the leaf plate 305b closes to block the air inlet hood 203.

[0080] During the process of the square rod 304a moving outwards, it continues to pull the toothed plate 305d, the connecting rod 306b, and the guide frame 306d to move, causing the toothed plate 305d to disengage from the gear 305c. The short rod 306c moves in the middle part of the guide frame 306d, being squeezed and moved downwards, thereby driving the vertical plate 306a to move downwards to block the frame body 104. The short block 304k moves outwards with the square rod 304a and can push the circular plate 304b to move, causing the circular plate 304b to disengage from the cylinder body 201, and thus one end of the shell 204 is exposed.

[0081] Then, the second part of the guide post 304i moves within the guide groove 304j, causing the cylinder 206 and the cleaning brush 208 thereon to rotate, cleaning the surface of the filter screen plate 207, and making it difficult for the dust cleaned down to enter the cabinet body 101 under the action of the plugging. Since the cleaning brush 208 is spirally arranged, the dust cleaned down can be discharged from the exposed end of the housing 204 under the action of rotation. After the cleaning is completed, the output shaft of the forward driving motor 304e is driven to reset the corresponding structure.

[0082] In summary, the air inlet filtering mechanism 200 can filter the gas entering the power distribution cabinet. Compared with the prior art, it reduces the probability of dust accumulation on the surface of the electrical components in the power distribution cabinet, reduces the influence on the heat dissipation effect of the electrical equipment and the occurrence of failures. The plugging and slag discharging mechanism 300 can adjust the rotation speed and air intake volume of the cooling fan according to the heat in the power distribution cabinet. Compared with the prior art, it makes the heat dissipation effect of the power distribution cabinet better, facilitates the cleaning of the filter plate used at the air inlet, makes it difficult for the fine dust generated during the cleaning process to enter the power distribution cabinet and is convenient for discharging.

[0083] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limitations. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
