Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a capacitor with explosion-proof and fire-extinguishing functions. Background Art

[0002] Two conductors close to each other, with a non-conductive insulating medium in between, form a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates.

[0003] Capacitors are prone to fire and explosion when abnormalities occur. However, the existing capacitors on the market do not have explosion-proof and fire-extinguishing functions. When a fire or explosion occurs, capacitor fragments will splash and cause the fire to overflow. For this reason, we propose a capacitor with explosion-proof and fire-extinguishing functions.

[0025] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0026] A capacitor with explosion-proof and fire-extinguishing functions comprises an explosion-proof shell 1, a mounting seat 2 is arranged at the bottom end of the explosion-proof shell 1, a capacitor body 3 is arranged inside the mounting seat 2, a circular groove 4 is opened in the middle of the top end of the explosion-proof shell 1, and a storage shell 5 is movably installed inside the circular groove 4; a discharge cover 6 is arranged at the upper end of the interior of the explosion-proof shell 1, a discharge mechanism 7 is arranged in the middle of the discharge cover 6, and the discharge mechanism 7 includes a double-axis motor 701, a threaded rod 702 and a sleeve 703; a bottom shell 8 is arranged on the outer side of the bottom end of the discharge cover 6, and a vibration mechanism 9 is arranged inside the bottom shell 8, and the vibration mechanism 9 includes a transmission shaft 901, Swing arm 902 and vibration block 903, a smoke sensor 10 is arranged at the middle of the bottom end of the bottom shell 8, a first thread groove 11 is arranged at the inner wall of the bottom end of the explosion-proof housing 1, a second thread groove 12 is arranged at the outer wall of the top end of the mounting seat 2, the mounting seat 2 is movably connected with the first thread groove 11 through the second thread groove 12, a plurality of discharge grooves 13 are arranged at the inner wall of the bottom end of the discharge cover 6, a sleeve 703 is arranged at the bottom end of the middle part of the storage shell 5, a double-axis motor 701 is arranged at the middle of the bottom end of the discharge cover 6, the output shaft at the top end of the double-axis motor 701 is fixedly connected to the threaded rod 702, and the threaded rod 702 is threadedly connected to the sleeve 703;

[0027] In this embodiment, if a fire occurs in the capacitor body 3, the smoke sensor 10 will sense it and then control the dual-axis motor 701 to rotate. After the dual-axis motor 701 rotates, it drives the threaded rod 702 to rotate. After the threaded rod 702 rotates, it drives the sleeve 703 to rise linearly. After the sleeve 703 rises, it lifts the storage shell 5. The flame retardant powder stored in the storage shell 5 will fall into the discharge cover 6, and then sprinkle along the discharge trough 13 to flame retard the capacitor body 3, thereby achieving the purpose of explosion-proof and flame retardant.

[0028] like Figure 3 As shown, the output shaft at the bottom end of the dual-axis motor 701 is fixedly connected to the transmission shaft 901, swing arms 902 are arranged on both sides of the transmission shaft 901, and a vibration block 903 is arranged at the other end of the swing arm 902;

[0029] In this embodiment, when the dual-axis motor 701 is started, the dual-axis motor 701 drives the transmission shaft 901 to rotate. After the transmission shaft 901 rotates, it drives the swing arm 902 to rotate and swing. After the swing arm 902 rotates and swings, it drives the vibration block 903 to hit the discharge cover 6. This can prevent the flame retardant powder from being blocked in the discharge cover 6, allowing the flame retardant powder to fall quickly.

[0030] like Figure 3 As shown, a plurality of scraper plates 14 are fixedly mounted on the outer side of the bottom end of the threaded rod 702, and the scraper plates 14 are slidably connected to the upper surface of the bottom end of the discharge cover 6;

[0031] In this embodiment, when the threaded rod 702 rotates, it drives the scraper plate 14 to quickly guide the flame retardant powder dropped on the discharge cover 6 into the discharge cover 6.

[0032] like Figure 2 As shown, a housing 15 is fixedly installed in the middle of the top of the storage shell 5, and a built-in power supply 16 is arranged inside the housing 15, and the built-in power supply 16 is electrically connected to the dual-axis motor 701 and the smoke sensor 10;

[0034] Working principle: When installing the capacitor body 3, place the capacitor body 3 inside the mounting seat 2, and then put the explosion-proof housing 1 in from above the mounting seat 2, and screw the explosion-proof housing 1 and the mounting seat 2 together through the first thread groove 11 and the second thread groove 12. When a fire occurs inside the capacitor body 3, the explosion-proof housing 1 can be used to prevent explosions. If the capacitor body 3 explodes, the explosion can be blocked by the explosion-proof housing 1 to prevent debris from splashing. If a fire occurs in the capacitor body 3, the smoke sensor 10 will sense it, and then control the dual-axis motor 701 to rotate, and the dual-axis motor 7 01 rotates and drives the threaded rod 702 to rotate. After the threaded rod 702 rotates, it drives the sleeve 703 to rise in a straight line. After the sleeve 703 rises, it lifts the storage shell 5. The flame retardant powder stored in the storage shell 5 will fall into the discharge cover 6, and then sprinkle along the discharge trough 13 to flame retard the capacitor body 3. When the dual-axis motor 701 is started, the dual-axis motor 701 drives the transmission shaft 901 to rotate. After the transmission shaft 901 rotates, it drives the swing arm 902 to rotate and swing. After the swing arm 902 rotates and swings, it drives the vibration block 903 to hit the discharge cover 6. This can prevent the flame retardant powder from being blocked in the discharge cover 6 and make the flame retardant powder fall quickly.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model.
