The inner walls of both sides of the assembly cover have grooves reserved in mirror image. The grooves are reserved outside the heat dissipation fins. The columns are screwed to the two sides of the grooves in mirror image. The upper outer wall of the column is screwed to the linkage bar. The side of the linkage bar farther from the column is screwed to the movable rod. The upper end of the movable rod is threaded through the upper wall of the outer side of the upper plate.

[0007] Furthermore, heat dissipation ports are provided on the heat dissipation plate.

[0008] Furthermore, three constraint rods are evenly fixed together with the air intake channel as the center, and the connecting column is a lead screw, with the side of the connecting column closest to the fan shaft having magnetic force.

[0009] Furthermore, the side of the blocking platform is movably clamped to the outer circumference of the constraint rod, wherein the radius of the blocking platform is equal to the outer radius of the air intake channel.

[0010] Furthermore, the side of the rubber cylinder farther from the blocking platform is fixed to the inner surface of the connecting seat, and the cavity inside the movable column and the cavity inside the rubber cylinder are connected through the rubber channel.

[0011] Furthermore, the inner walls on both sides of the upper end of the assembly cover have mirror-image pre-reserved assembly ports. Rubber cylinder two is fixedly embedded in the assembly ports.

[0015] The beneficial effects of this invention are as follows: 1. The temperature sensor of this invention monitors the internal temperature of the capacitor body. When the internal temperature of the capacitor body rises to a specified range, the temperature sensor transmits the temperature signal to the controller. The controller controls the servo motor, which rotates the screw. Because the screw is threaded to the sleeve and, with the cooperation of the insulating bracket and the insulating slide plate, the insulating slide plate moves horizontally. This causes the elastic conductive sheet on the insulating slide plate to move out of the space between the lower and upper terminals. At this time, the lower and upper terminals are disconnected, and the capacitor body is de-energized and stops working. This effectively prevents the capacitor body from continuing to work and causing it to continue to heat up and burn out, greatly improving the safety of use and extending its service life. When the temperature of the capacitor body drops to the set temperature, the servo motor pulls the screw to rotate in the opposite direction. Because the screw is threaded with the sleeve, and with the cooperation of the insulating bracket and the insulating slide plate, the insulating slide plate is moved horizontally. Then, the elastic conductive sheet on the insulating slide plate moves into the space between the lower terminal and the upper terminal. At this time, the two sides of the elastic conductive sheet are tightly attached to the lower terminal and the upper terminal, and then the lower terminal and the upper terminal are electrically connected through the elastic conductive sheet. At this moment, the capacitor body can work normally.

[0016] The present invention can cool the overheated capacitor body through a cooling module, ensuring that the capacitor body can be quickly put back into operation.

[0017] In this invention, the capacitor body is assembled in an assembly cover. Heat dissipation plates on the assembly cover remove Joule heat generated during capacitor body operation. Heat transfer blocks are installed on the capacitor body to rapidly remove Joule heat generated during operation, ensuring the capacitor body cools down quickly before resuming operation. During capacitor body operation, a fan is powered on and operates, drawing cool air from outside into the assembly cover and transferring hot air from the assembly cover away via the heat dissipation plates. This accelerates gas movement within the assembly cover, enhancing the capacitor body's heat dissipation function. A blocking platform is installed outside the air inlet channel, threadedly connected to a connecting post. When the fan rotates, a magnet drives the connecting post to rotate, causing the blocking platform to follow the constraint... As the rod moves towards the connecting seat, it opens the air inlet channel. When the blocking platform can no longer move along the restraining rod, the connecting column remains stationary, while the fan rotates continuously. Initially, the blocking platform closes the air inlet channel to prevent debris from falling into the assembly cover when the capacitor is not running, as the inside of the assembly cover remains open. As the blocking platform moves towards the connecting seat, it presses against the rubber cylinder. The connecting column and the fan shaft are connected by a strong magnetic force. Initially, the connecting column rotates continuously, pressing against the rubber cylinder via the blocking platform, causing the gas inside the rubber cylinder to be transferred to the movable column, extending it upwards until the upper plate rises. At this point, the air inlet channel is also opened. Then, when the fan opens the air inlet channel and sends air into the assembly cover, the... When the upper plate is open, the heat dissipation function of the capacitor body is enhanced, ensuring that the capacitor body can quickly restart. When the upper plate moves upward, it will pull the movable rod to rotate via the threaded joint. The rotation of the movable rod will pull the linkage bar at its lower end to rotate, which in turn will pull the column connected to the linkage bar to rotate. Then, the movable rod on the column will move upward in the groove via the threaded joint, which will press the folding block to fold it. When used in the air inlet channel, it will connect the heat dissipation plate to the outside. Then, it will assist the blocking platform and the upper plate in completely opening the side walls and upper walls of the assembly cover when the fan is running to assist in heat dissipation and enhance the heat dissipation function of the capacitor body. After the capacitor body has finished heat dissipating, the fan rotates in the reverse direction to pull the blocking platform to block the air inlet channel, and pull the upper plate to press the upper end of the assembly cover again. The blockage is then tightened, and the folding block is slowly unfolded again to shield the heat dissipation plate. After the capacitor body has finished heat dissipating, the cavity inside the assembly cover is fully shielded to prevent the cavity inside the assembly cover from being in contact with the outside for a long time, which would cause dust and other waste to stick to the capacitor body. When the first rubber cylinder is compressed, the gas inside it will be transferred to the second rubber cylinder, which will then slowly expand, driving the interlocking platform to move outward along the assembly opening until it is interlocked between the heat transfer blocks on the capacitor body. Then, when the upper plate is opened, it will automatically interlock between the interlocking platform and the heat transfer blocks. Finally, the upper end of the capacitor body will be interlocked and fixed to prevent the capacitor body from shaking vertically in the assembly cover after the upper end of the capacitor body is opened, which would be detrimental to the normal use of the capacitor body.Furthermore, as the movable rod moves downwards, it applies pressure to the movable plate, causing it to gradually shorten and transferring the gas inside to the rubber cylinder three in the auxiliary opening. This causes the rubber cylinder three to expand outwards, driving the leak-proof strip to move outwards towards the auxiliary opening until it presses firmly against the walls of the flattened folding block. Then, as the folding block closes against the heat dissipation plate, it simultaneously applies pressure to both sides of the folding block, preventing moisture, dust, etc., from entering the assembly cover through the sides of the folding block, thus ensuring the normal operation of the capacitor body.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Reference Figures 1-2 This invention provides a self-ignition resistant capacitor, comprising a capacitor body 1, a grounding terminal 2 and a power connection terminal 3 mounted on the capacitor body 1, an overheat power-off unit 4 mounted on the power connection terminal 3, and a controller 5 mounted on the capacitor body 1.

[0022] The power terminal 3 includes several insulating supports 31 fixed to the capacitor body 1 and a lower terminal 32 installed on the capacitor body 1. An upper terminal 33 is fixed between each pair of insulating supports 31, and a space for movement is reserved between the upper terminal 33 and the lower terminal 32.

[0023] The overheat protection unit 4 includes an insulating slide plate 41 movably mounted between insulating supports 31, an insulating support 43 fixed to the capacitor body 1, and a temperature sensor embedded inside the capacitor body 1. An elastic conductive sheet 42 is fixedly connected to the insulating slide plate 41, and the elastic conductive sheet 42 is V-shaped. Both sides of the elastic conductive sheet 42 are tightly connected to the lower terminal 32 and the upper terminal 33. A servo motor 44 is mounted on the insulating support 43. The output end of the servo motor 44 is fixedly connected to a screw 45. A screw sleeve 46 is threaded onto the outer circumference of the screw 45. The screw sleeve 46 is fixed to one side of the insulating slide plate 41. The temperature sensor, the servo motor 44, and the controller 5 are electrically connected. The temperature sensor, the servo motor 44, and the controller 5 are all existing technologies and will not be described in detail here.

[0024] The temperature sensor monitors the internal temperature of the capacitor body 1. When the internal temperature of the capacitor body 1 rises to a specified range, the temperature sensor transmits the temperature signal to the controller 5. The controller 5 controls the servo motor 44, which pulls the screw 45 to rotate. Since the screw 45 is threaded to the sleeve 46, and with the cooperation of the insulating bracket 31 and the insulating slide plate 41, the insulating slide plate 41 is moved horizontally. This causes the elastic conductive sheet 42 on the insulating slide plate 41 to move out of the space between the lower terminal 32 and the upper terminal 33. At this time, the lower terminal 32 and the upper terminal 33 are disconnected, and the capacitor body 1 is de-energized and stops working. This effectively prevents the capacitor body 1 from continuing to work and causing it to continue to heat up and burn out naturally, greatly improving the safety of use and extending its service life. When the temperature of the capacitor body 1 drops to the set temperature, the servo motor 44 pulls the screw 45 to rotate in the opposite direction. Since the screw 45 is threaded with the screw sleeve 46, and with the cooperation of the insulating bracket 31 and the insulating slide plate 41, the insulating slide plate 41 is moved horizontally. Then, the elastic conductive sheet 42 on the insulating slide plate 41 moves into the movable space between the lower terminal 32 and the upper terminal 33. At this time, both sides of the elastic conductive sheet 42 are tightly attached to the lower terminal 32 and the upper terminal 33, and then the lower terminal 32 and the upper terminal 33 are electrically connected through the elastic conductive sheet 42. At this moment, the capacitor body 1 can work normally.

[0025] Example 2 Reference Figures 3-10 The difference from Embodiment 1 is that a cooling module is installed on the outside of the capacitor body 1.

[0026] The cooling module can cool the overheated capacitor body 1, ensuring that the capacitor body 1 can be put back into operation quickly.

[0027] The cooling module includes a mounting cover 6 assembled on the outside of the capacitor body 1, with an upper plate 7 mounted on the upper end of the mounting cover 6, and also includes: Heat dissipation unit 9 is fixedly connected to assembly cover 6; Reinforcing unit 10 is also fixedly connected to assembly cover 6; In this configuration, the vertical sides of the capacitor body 1 and the bottom of the upper plate 7 are connected to the lower end of the upper wall of the mounting cover 6 through a fixed connection, and a heat transfer block 11 is fixedly connected to the outer wall of the capacitor body 1.

[0028] The heat dissipation unit 9 includes a heat dissipation plate 91, which is mirror-connected to the outer wall surfaces of both sides of the assembly cover 6. The heat dissipation plate 91 has a heat dissipation port. The outer wall surfaces of both sides of the heat dissipation plate 91 are mirror-connected to the air inlet channel 92. The air inlet channel 92 is connected to the fan 93 by a connecting strip. The fan 93, the temperature sensor and the controller 5 are electrically connected.

[0029] A constraint rod 94 is fixed to the side wall of the air intake channel 92 that is farthest from the assembly cover 6. Three constraint rods 94 are evenly fixed around the air intake channel 92. A connecting seat 95 is fixed to the side of the constraint rod 94 that is farthest from the air intake channel 92. A connecting post 96 is rotatably inserted through the center of the connecting seat 95. A thread is reserved on the outer circumference of the connecting post 96. The side of the connecting post 96 that is farthest from the connecting seat 95 is screwed onto the shaft of the fan 93. The side of the connecting post 96 that is close to the shaft of the fan 93 has magnetic force.

[0030] A plug 97 is threaded onto the outer circumferential surface of the connecting column 96. The side of the plug 97 is movably clamped onto the outer circumferential surface of the constraint rod 94. The radius of the plug 97 is equal to the outer radius of the air inlet channel 92.

[0031] Reference Figures 3-10 The reinforcing unit 10 includes a rubber cylinder 101, which is fixed to the outer wall of the blocking platform 97. The side of the rubber cylinder 101 that is farther from the blocking platform 97 is fixed to the inner surface of the connecting seat 95. A movable column 102 is fixed to the lower side wall of the upper plate 7. The movable column 102 includes an outer cylinder, an inner rod, and a spring. One end of the inner rod is movably installed in the outer cylinder. The inner rod is connected to the outer cylinder by the spring. The movable column 102 is inserted and fixed to the upper wall of the upper side of the assembly cover 6. The cavity inside the movable column 102 and the cavity inside the rubber cylinder 101 are connected through a rubber channel.

[0032] Assembly ports 103 are mirror-reserved on the inner walls of both sides of the upper end of the assembly cover 6. Rubber cylinder 2 104 is fixedly embedded in the assembly port 103. The cavity inside the rubber cylinder 2 104 is connected to the cavity inside the rubber cylinder 1 101 through a rubber channel. An inserting platform 105 is fixedly attached to the outer wall of the rubber cylinder 2 104. The inserting platform 105 is movably embedded in the assembly port 103.

[0033] The inner walls of the assembly cover 6 are mirror-image reserved with grooves 106. The grooves 106 are reserved on the outside of the heat dissipation plate 91. The grooves 106 are mirror-image screwed to the two sides with columns 107. The columns 107 are lead screws. The movable rod 108 is screwed to the column 107 on the same side. The upper end of the movable rod 108 is fixed to the folding block 109. The folding block 109 is located outside the heat dissipation plate 91.

[0034] A linkage bar 1010 is screwed onto the outer wall of the upper end of the column 107. A movable rod 1011 is screwed onto the side of the linkage bar 1010 that is farther away from the column 107. The movable rod 1011 is screwed onto the outer wall of the upper end of the assembly cover 6. The movable rod 1011 is a lead screw, and the upper end of the movable rod 1011 is threaded onto the upper wall of the outer side of the upper plate 7.

[0035] The lower end of the channel 106 is fixedly connected to the movable plate 1012. The movable plate 1012 includes an outer cover, an inner plate, and a spring. One end of the inner plate is movably installed in the outer cover. The outer cover and the inner plate are connected by the spring. The movable plate 1012 is located at the bottom of the movable rod 108. Assistive openings 1013 are reserved on both sides of the channel 106. The assistive openings 1013 are located inside the wall of the assembly cover 6. A rubber cylinder 1014 is fixedly connected in the assistive opening 1013. The cavity inside the rubber cylinder 1014 is connected to the cavity inside the movable plate 1012. A leak-proof strip 1015 is fixedly connected to the outer wall of the rubber cylinder 1014. The leak-proof strip 1015 is movably installed in the assistive opening 1013. The side of the leak-proof strip 1015 furthest from the rubber cylinder 1014 is aligned with the outer wall surfaces of both sides of the folding block 109.

[0036] In use, the capacitor body 1 is assembled in the assembly cover 6. The Joule heat generated by the operation of the capacitor body 1 is removed by the heat dissipation plate 91 on the assembly cover 6. The Joule heat generated by the operation of the capacitor body 1 is quickly removed by the heat transfer block 11 installed on the capacitor body 1, thereby ensuring that the capacitor body 1 can cool down quickly and start operation again. During the operation of the capacitor body 1, the fan 93 is powered on and operates. The rotation of the fan 93 draws cold air from the outside into the assembly cover 6 and removes the hot air in the assembly cover 6 through the heat dissipation plate 91, thereby accelerating the movement of gas in the assembly cover 6 and enhancing the heat dissipation function of the capacitor body 1. Because a blocking platform 97 is installed outside the air inlet channel 92, the blocking platform 97 is connected to the connecting column 9. 6. When the fan 93 rotates, the connecting column 96 is driven to rotate by a magnet, causing the blocking platform 97 to move along the constraint bar 94 towards the connecting seat 95, opening the air intake passage 92. When the blocking platform 97 can no longer move along the constraint bar 94, the connecting column 96 stops, while the fan 93 continues to rotate. Initially, the blocking platform 97 closes the air intake passage 92 to prevent debris from falling into the assembly cover 6 when it is not running, as the assembly cover 6 remains open. When the blocking platform 97 moves towards the connecting seat 95, it presses against the rubber sleeve 101. The connecting column 96 and the shaft of the fan 93 are connected by a strong magnetic force. Initially, the connecting column 96 will rotate continuously, pressing against the rubber sleeve 101 via the blocking platform 97. Pressurization is applied by rubber cylinder 101, which transfers the gas inside to movable column 102, causing movable column 102 to extend upwards until the upper plate 7 is raised. At this moment, the air inlet channel 92 is also opened. Subsequently, when the fan 93 opens the air inlet channel 92 to send air into the assembly cover 6, the upper plate 7 is opened simultaneously, enhancing the heat dissipation function of the capacitor body 1 and ensuring that the capacitor body 1 can quickly restart. When the upper plate 7 moves upwards, it will rotate the movable rod 1011 via the threaded connection. When the movable rod 1011 rotates, it will pull the linkage bar 1010 at its lower end to rotate, which in turn pulls the column 107 connected to the linkage bar 1010 to rotate. Then, the movable rod 108 on the column 107 will be pulled to rotate in the trench 106. When the upper part changes, it applies pressure to the folding block 109 to fold it. When the air inlet channel 92 is in use, it connects the heat dissipation plate 91 to the outside. Then, it assists the blocking platform 97 and the upper plate 7 in completely opening the side walls and upper walls of the assembly cover 6 when the fan 93 is running to assist in heat dissipation and enhance the heat dissipation function of the capacitor body 1. After the capacitor body 1 is heat-dissipated, the fan 93 rotates in the reverse direction to pull the blocking platform 97 to block the air inlet channel 92, and pulls the upper plate 7 to block the upper end of the assembly cover 6 again. It also pulls the folding block 109 to slowly unfold and shield the heat dissipation plate 91. After the capacitor body 1 is heat-dissipated, the cavity inside the assembly cover 6 is fully shielded to prevent the cavity inside the assembly cover 6 from being connected to the outside for a long time, which would cause dust and other waste to stick to the capacitor body 1.When rubber cylinder 101 is compressed, the gas inside is transferred to rubber cylinder 2 104, causing rubber cylinder 2 104 to gradually expand. This drives the fitting platform 105 to move outward along the assembly port 103 until it is fitted between the heat transfer block 11 on the capacitor body 1. Then, when the upper plate 7 is opened, it automatically fits between the fitting platform 105 and the heat transfer block 11, thus securing the upper end of the capacitor body 1. This prevents the capacitor body 1 from shaking vertically within the assembly cover 6 after the upper end of the capacitor body 1 is opened, which would be detrimental to the normal operation of the capacitor body 1. Furthermore, the movable rod 108 moves downward... During operation, pressure is applied to the movable plate 1012, causing it to gradually shorten and transferring the gas inside to the rubber cylinder 1014 in the auxiliary port 1013. This causes the rubber cylinder 1014 to expand outwards, driving the leak-proof strip 1015 to move outwards from the auxiliary port 1013 until it presses firmly against the walls of the flattened folding block 109. Then, when the folding block 109 closes to the heat dissipation plate 91, it further compresses and blocks both sides of the folding block 109, preventing moisture, dust, etc., from entering the assembly cover 6 through the sides of the folding block 109, thus ensuring the normal operation of the capacitor body 1.
