Through the application of advanced sensing and measurement technology, advanced equipment technology, advanced control methods and advanced decision support system technology, it realizes the goals of reliable, safe, economical, efficient, environmentally friendly and safe use of power grid. When building smart grid, it is necessary to install heat dissipation distribution cabinets to provide location and protection for the installation of electrical components, as well as to ventilate and dissipate heat for the electrical components.

[0003] However, in practical applications, there are still some unresolved issues. The following are some common issues with heat dissipation distribution cabinets based on smart grids: The existing technology cannot adjust the speed and air intake of the cooling fan according to the heat in the distribution cabinet, which will lead to poor heat dissipation of the distribution cabinet and continuous increase in internal temperature, which may cause equipment failure and safety hazards. It is also inconvenient to clean the filter plate used at the air inlet. Since the fan is always running, the fine dust generated during the cleaning process enters the distribution cabinet under the suction of the fan, affecting the electrical components in the distribution cabinet.

DETAILED DESCRIPTION

[0034] 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.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0037] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, and this embodiment provides a heat dissipation type power distribution cabinet based on smart grid. The heat dissipation type power distribution cabinet based on smart grid includes a power distribution cabinet mechanism 100, an air inlet filter mechanism 200 and a blocking and slag removal mechanism 300. The air inlet filter mechanism 200 can filter the gas entering the power distribution cabinet, and the blocking and slag removal mechanism 300 can adjust the speed and air intake volume of the cooling fan according to the heat in the power distribution cabinet, so as to facilitate the cleaning of the filter plate used at the air inlet.

[0038] Specifically, the 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, and 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 by means of a hinge, the air outlet plate 103 is fixedly connected to the surface of the cabinet body 101 by means of screws, and a through hole is provided on its surface to facilitate exhaust and heat dissipation, the fan 105 is fixedly connected to the inner wall of the frame body 104 by means of bolts, and the operation of the fan 105 transmits external gas into the cabinet body 101, and then is discharged from the air outlet plate 103, so that the air in the distribution cabinet can flow and improve the heat dissipation effect.

[0040] Specifically, the air inlet filtering mechanism 200 is installed on the surface of the frame 104, and includes a cylinder 201, a curved pipe 202, an air inlet hood 203, a shell 204, a round block 205, a cylinder 206, a filter screen 207, a cleaning brush 208, a transparent window 209 and an air outlet 210. The cylinder 201 is connected to the surface of the frame 104, and the two ends of the curved pipe 202 are respectively connected to the air inlet hood 203 and the cylinder 201. The shell 204 is fixedly connected to the inner wall of the cylinder 201, the round block 205 is fixedly connected to the surface of the shell 204, the cylinder 206 is rotatably connected to the curved pipe 202 and the surface of the round block 205, the filter screen 207 is movably connected to the surface of the shell 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 201, and the air outlet 210 is opened on the surface of the cylinder 206.

[0041] Both ends of the elbow pipe 202 are fixedly connected to the intake hood 203 and the surface of the cylinder body 201 respectively, preventing air leakage through gaps during the air intake process. The cylinder 206 is rotatably sleeved on one end of the elbow pipe 202 through a sealed bearing. The elbow pipe 202 keeps the intake hood 203 and the cylinder 206 in communication, enabling the air entering the intake hood 203 to enter the cylinder 206 through the elbow pipe 202, and then discharging into the housing 204 through the air outlet holes 210. The filter screen plate 207 filters the gas that enters and then exits the housing 204, and then enters the cabinet 101 through the frame 104 for ventilation and heat dissipation.

[0042] The cleaning brush 208 is fixedly connected to the surface of the cylinder 206 through a support rod. Under the action of the rotation of the cylinder 206 driving the cleaning brush 208 to rotate, the dust attached to the surface of the filter screen plate 207 can be cleaned. A sealing sleeve is provided between the cylinder 206 and the round block 205, and it does not affect their relative rotation. The number of air outlet holes 210 is several, enabling the gas entering the cylinder 206 to be discharged from multiple directions. The transparent window 209 facilitates observing whether the filter screen plate 207 is in the installation position.

[0043] Specifically, the plugging and slag discharging mechanism 300 is installed on the surfaces of the air intake filtering mechanism 200, the frame 104, and the air outlet plate 103, and includes an adjusting member 301, a switch 302, a touching member 303, a driving member 304, an air intake 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 touching member 303 is arranged on the surfaces of the elbow pipe 202 and the cylinder 206. The driving member 304 is arranged on the surfaces of the cylinder 206 and the shielding member 306. The air intake adjusting member 305 is arranged on the surfaces of the intake hood 203 and the shielding member 306. The shielding member 306 is arranged on the surfaces of the frame 104 and the driving member 304. The fixing member 307 is installed on the surfaces of the housing 204 and the round block 205.

[0044] By adjusting the change in the resistance value in the connected circuit through the adjusting member 301, the on-off and current magnitude of the series circuit are controlled through 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 turned off through the switch 302 during maintenance. The on-off of the series circuit and the total resistance value in the connected circuit can be controlled by the position of the conductive ring 301d on the resistor 301a. Under the same constant voltage, the magnitude of the current in the circuit is changed, thereby controlling the repulsive force generated by the electromagnet 303b and the power of the fan 105.

[0045] The touch member 303 is triggered by the different repulsive forces generated by the power supply of the electromagnet 303b, and then the air inlet adjustment member 305 is adjusted under the operation of the driving member 304, so as to realize the function of adjusting the size of the air inlet according to the temperature in the cabinet 101. When the temperature is low and the power is cut off, the operation of 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 201, so as to clean the filter plate 207 and facilitate the discharge of the cleaned dust.

[0046] The shielding member 306 is used to seal the frame 104 after power failure and before cleaning to prevent dust from being sucked into the cabinet 101 during the cleaning process due to the inertia of the fan blades. When the fan 105 is powered on for a moment, air will not be drawn in from the exposed end of the cylinder 201. Only when the circular plate 304b contacts the cylinder 201 can the shielding member 306 no longer block the frame 104, thereby achieving normal air intake through the air intake hood 203. Example 2

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

[0048] Specifically, the adjusting member 301 includes a resistor 301a, a round shell 301b, a sliding rod 301c, a conductive ring 301d, a piston 301e, a molten metal 301f, a first spring 301g and a heat-conducting rod 301h. The resistor 301a and the round shell 301b are installed on the surface of the gas outlet plate 103. The sliding rod 301c is slidably connected to the surface of the round shell 301b. The conductive ring 301d is fixedly connected to one end of the sliding rod 301c and is 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 round shell 301b. The molten metal 301f is filled in the inner cavity of the round 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 round shell 301b and the piston 301e. The heat-conducting rod 301h is fixedly connected to the surface of the round 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 are equivalent to a sliding rheostat. It is a prior art and will not be described in detail here. The sliding rod 301c penetrates the circular shell 301b and is slidably connected thereto. The metal liquid 301f is mercury or a heat-sensitive substance similar to mercury, such as gallium and its alloys. Under the action of thermal expansion, it can push the piston 301e to move, and then the sliding rod 301c pushes the conductive ring 301d to move on the surface of the resistor 301a, thereby changing the current in the series circuit.

[0050] When the temperature drops, the molten metal 301f shrinks, and the first spring 301g is used to rebound so that the piston 301e, the slide rod 301c and the conductive ring 301d move back, thereby increasing the total resistance in the circuit. The power can even be cut off when the temperature is low so that the fan 105 no longer runs to save electricity. The heat dissipation requirement can be met through natural ventilation. There are several heat conducting rods 301h, and they are all fixedly connected to the surface of the round shell 301b. Through the heat conducting rods 301h, the molten metal 301f can be heated or cooled according to the temperature of the gas in the cabinet 101 by means of heat exchange, so as to adjust the resistance in the series circuit according to the temperature change.

[0051] The contact member 303 includes a hollow rod 303a, an electromagnet 303b, a shell 303c, a first contactor 303d, a second contactor 303e and a force-applying member 303f. The hollow rod 303a is fixedly connected to the surface of the curved 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 shell 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 shell 303c, and the force-applying member 303f is installed on the surface of the shell 303c.

[0052] The cylinder 206 is rotatably connected to the surface of the hollow rod 303a through a sealed bearing, the shell 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, and controlling the operation of the motor 304e and the number of rotations of the output shaft through a relay is a prior art and will not be repeated here. The repulsive force generated by energizing the electromagnet 303b acts on the force-applying member 303f, thereby achieving the first contactor 303d and the second contactor 303e being triggered at different stages.

[0053] The driving member 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 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 are in contact with the surfaces of the connecting plate 304c and the circular plate 304b respectively, 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, and the other end of the reciprocating roller 304f is rotatably connected to the surface of the shell 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, and 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 thereto and is sealed. A reciprocating groove matching 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] The second spring 304d exerts pressure on the connecting plate 304c, and 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 a 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 inside. The second part is the guide column 304i, which can cause the cylinder 206 to rotate when it moves inside, 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, 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 stop block 304L moves outward with the square rod 304a to act on the fixing member 307, so that the fixing member 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 penetrates the frame 104 and is slidably connected thereto, 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, the air inlet adjustment member 305 is adjusted without being affected. The short rod 306c moves in the middle part to move the vertical plate 306a. At this time, advance preparation is made for cleaning the filter screen plate 207, or after the fan 105 is turned on and the circular plate 304b is brought into contact with the cylinder 201, the blockage of the frame 104 is released to 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 Figure 6 to Figure 15 , which is the third embodiment of the present invention, and 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 rod 305a is rotatably connected to the surface of the air intake cover 203 through a bearing, and the blades 305b are fixedly connected to the surface of the rotating rod 305a. Two adjacent connecting blocks 305e are indirectly connected through a movable plate 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 tooth plate 305d can drive the gear 305c to rotate, and then the rotating rod 305a can rotate, so as to adjust the angle of the vane 305b and the size of the air intake. Under the action of the torsion force of the torsion spring 305h, the rotating rod 305a is more stable when rotating, and at the same time, power is provided for the rotation and reset of the rotating rod 305a and the vane 305b.

[0065] The fixing member 307 includes a groove 307a, a clamping plate 307b, a third spring 307c and a push rod 307d. The groove 307a is opened in the shell 204, and 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 push rod 307d is slidably connected to the surface of the shell 204 and the round block 205, and contacts the surface of the clamping plate 307b. A clamping groove is opened on the surface of the filter screen plate 207, and one end of the clamping plate 307b passes through the shell 204 and extends to the inner cavity of the clamping groove and contacts its inner wall.

[0066] One end of the card plate 307b inserted into the slot is chamfered, so that when the filter screen plate 207 is installed, the filter screen plate 207 squeezes the card plate 307b to move it, thereby compressing the third spring 307c. When one end of the card plate 307b is directly opposite to the slot, the card plate 307b is inserted into the slot under the action of the elastic force of the third spring 307c, and the square rod 304a moves outward to drive the block 304L to move and contact the block 307d, squeezing it upward, and then squeezing and pushing the card plate 307b to move, so that one end of the card plate 307b is separated from the slot, losing the limit on the filter screen plate 207, and the filter screen plate 207 is convenient to remove for deep cleaning or replacement.

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

[0068] The first connecting rod 303f-1 passes through the shell 303c and is slidably connected thereto. When the conductive ring 301d is just connected to 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 pressure block 303f-3, the second connecting rod 303f-6, the second iron block 303f-7, the fifth spring 303f-9, the second pressure block 303f-8 and the connecting plate 303f-5 to move, so that the fourth spring 303f-4 is stretched to bring the first pressure block 303f-3 into contact with the first contactor 303d, and the first state of operation is performed, so that the leaf plate 305b is opened 45 degrees.

[0069] When the conductive ring 301d moves to the end of the resistor 301a, the current in the circuit is the largest, and the second iron block 303f-7, the second connecting rod 303f-6 and the second pressure block 303f-8 continue to be pushed to move, so that the fifth spring 303f-9 is stretched, and the second pressure block 303f-8 contacts the second contactor 303e, and operates in the second state, so that the blade 305b is opened 90 degrees to achieve maximum air intake.

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

[0071] The cover body 106 is used to shield the cylinder body 201 and part of the structure from exposure, the baffle 107 is used to shield the top of the air inlet cover 203 to prevent the entry of debris and rainwater, and the rain shield 108 is used to block water from the cabinet body 101 in rainy and snowy weather.

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

[0073] A positioning rod is fixedly connected to the surface of the shell 204, and a positioning hole is opened on the surface of the filter plate 207. The positioning rod is inserted into the positioning hole. The positioning rod and the positioning hole can be used to facilitate the initial and accurate positioning of the filter plate 207 on the shell 204, so as to facilitate subsequent fixing by the fixing piece 307.

[0074] When in use, the present invention has three working states. In the first working state, the heat in the cabinet 101 is conducted through the heat conducting rod 301h to expand the molten metal 301f, so that the conductive ring 301d contacts the resistor 301a, and the blade 305b is opened 45 degrees and the fan 105 is running. At this time, it is a passage. When the molten metal 301f expands and pushes the piston 301e to move, the slide rod 301c and the conductive ring 301d are moved, 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 pressure 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 in the positive direction for a certain number of circles and stop, and then the short column 304h drives the guide column 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 column 304i moves in the first part of the guide groove 304j, and the cylinder 206 will not rotate. The upper part of the short rod 306c on the guide frame 306d moves, 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 the blade 305b are rotated, and the torsion spring 305h is deformed, so that the blade 305b is opened 45 degrees to allow air to enter.

[0076] The second working state is when the heat inside the cabinet 101 is high, the metal liquid 301f is expanded by heat conduction of the heat conducting rod 301h to move the conductive ring 301d to the end of the resistor 301a, so that the blade 305b is opened 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 continues to increase, increasing the speed of the fan 105 blades. When the current reaches the repulsive force generated by the electromagnet 303b, the second iron block 303f-7, the second connecting rod 303f-6 and the second pressure block 303f-8 are moved, the fifth spring 303f-9 is stretched, and the second pressure block 303f-8 is in contact with 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 a certain number of times and then stop, which is the same as the operating principle of the corresponding structure in the first state, so that the blade 305b opens 90 degrees to let in air, thereby increasing the air intake and heat dissipation efficiency, and adjusting the number of revolutions and air intake size of the fan 105 according to the heat in the distribution cabinet.

[0078] The third working state is when the temperature inside the cabinet 101 is low, the metal liquid 301f shrinks and the first spring 301g rebounds, causing the conductive ring 301d to separate from the resistor 301a to cut off the power, and the fan 105 stops running to save electricity. At this time, the filter plate 207 is cleaned and dust is discharged. After power is cut off, the electromagnet 303b will not generate repulsive force. Under the action of the fourth spring 303f-4 and the fifth spring 303f-9, the first pressure block 303f-3 is separated from the first contactor 303d, and the second pressure block 303f-8 is separated 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 in the opposite direction for a certain number of circles and then stop. During this process, the tooth plate 305d, the gear 305c, the rotating rod 305a and the blade 305b are first reset, and the blade 305b is closed to block the air intake hood 203.

[0080] As the square rod 304a moves outward, the tooth plate 305d, the connecting rod 306b and the guide frame 306d are continuously pulled to move, so that the tooth plate 305d is disengaged from the gear 305c, and the short rod 306c moves in the middle part of the guide frame 306d, squeezing and moving the short rod 306c downward, thereby driving the vertical plate 306a to move downward to block the frame 104, and 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 leaks out.

[0081] Then the guide column 304i moves in the second part of the guide groove 304j, so that the cylinder 206 and the cleaning brush 208 thereon rotate, and the surface of the filter plate 207 is cleaned. Under the effect of blocking, the cleaned dust is not easy to enter the cabinet 101. Due to the spiral setting of the cleaning brush 208, the cleaned dust can be discharged from the exposed end of the shell 204 under the effect of rotation. After cleaning, the output shaft of the forward drive motor 304e is reset to reset the corresponding structure.

[0082] In summary, the air entering the distribution cabinet can be filtered through the air inlet filtering mechanism 200. Compared with the prior art, the probability of dust accumulation on the surface of electrical components in the distribution cabinet is reduced, and the influence on the heat dissipation effect and the occurrence of malfunctions of the electrical equipment is reduced. The speed and air intake volume of the cooling fan can be adjusted according to the heat in the distribution cabinet through the sealing and slag discharge mechanism 300. Compared with the prior art, the heat dissipation effect of the distribution cabinet is better, and the filter plate used at the air inlet is convenient to clean. The fine dust generated during the cleaning process is not easy to enter the distribution cabinet and can be easily discharged.

[0083] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
