Some existing explosion-proof linear electric actuators lack effective heat dissipation mechanisms, which can easily lead to excessive internal temperature during use, affecting the operation of the power control components. Therefore, an explosion-proof linear electric actuator is proposed to address the above problems. Utility Model Content

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] An explosion-proof linear electric actuator includes a main body 1 and a heat-conducting component 2. The heat-conducting component 2 is located on the left side of the main body 1, and an isolation cover assembly 3 is located outside the heat-conducting component 2. A cooling chamber assembly 4 is located outside the isolation cover assembly 3, and an air supply assembly 5 is located on the upper side of the cooling chamber assembly 4. The main body 1 includes an actuator body 11 and an external threaded pipe 12. The external threaded pipe 12 is welded to the left half of the actuator body 11, and a power controller 13 is fixedly connected to the left side of the actuator body 11. The heat-conducting component 2 includes a heat-conducting shell 21 and heat-conducting columns 22. The heat-conducting shell 21 is fixedly connected to the left side of the actuator body 11, and multiple sets of heat-conducting columns 22 are fixedly connected to the left side of the heat-conducting shell 21. The isolation cover assembly 3 includes an isolation cover body 31 and an internal threaded pipe 32. The right side of the isolation cover body 31 is welded with... The system includes an internally threaded pipe 32, which is threadedly connected to an externally threaded pipe 12. A recess 33 is provided on the left side of the isolation cover body 31. The cooling chamber assembly 4 includes a cooling chamber body 41 and a support column 42. A set of support columns 42 is fixedly connected to the left side of the interior of the cooling chamber body 41. The right side of the support column 42 is fixedly connected to the isolation cover body 31. A set of spiral plates 43 is fixedly connected to the inner side of the cooling chamber body 41. The inner side of the spiral plates 43 is fixedly connected to the isolation cover body 31. The air supply assembly 5 includes a gas pump 51 and a mounting base 52. The mounting base 52 is fixedly connected to the lower side of the gas pump 51. The lower side of the mounting base 52 is fixedly connected to the cooling chamber body 41. An air supply pipe 53 is fixedly connected to the right side of the gas pump 51. The lower side of the air supply pipe 53 is fixedly connected to the air inlet of the cooling chamber body 41.

[0025] The outer side of the externally threaded tube 12 has threaded protrusions, and the inner side of the internally threaded tube 32 has threaded grooves. The heat-conducting shell 21 is composed of a grooved circular plate and a rectangular shell. The heat generated by the power controller 13 can be quickly conducted to the heat-conducting columns 22 through the heat-conducting shell 21. The heat-conducting columns 22 are circumferentially distributed, and each group of heat-conducting columns 22 is composed of multiple bent metal columns of different lengths. The end of the heat-conducting column 22 away from the heat-conducting shell 21 is in contact with the isolation cover body 31. Through multiple heat-conducting columns 22 of different shapes, heat can be quickly conducted to all parts of the isolation cover body 31, and then the heat can be conducted to the spiral plate. 43 is fixedly connected to the outer side of the internal threaded pipe 32 and the cooling chamber body 41. The length of the spiral plate 43 in the left and right directions is equal to the length of the isolation cover body 31 in the left and right directions. The spiral plate 43 can divide the space between the cooling chamber body 41, the recessed part 33, and the internal threaded pipe 32 into a spiral air duct. An air inlet is provided on the upper side of the cooling chamber body 41, and an air outlet is provided on the left side of the cooling chamber body 41. The support columns 42 are circumferentially distributed, and the spiral plates 43 are circumferentially distributed. Air enters the spiral air duct and flows spirally along the air duct, which can quickly remove the heat on the isolation cover body 31 and the spiral plate 43.

[0026] Working process: Before use, install the device in a suitable position, thread the internal threaded pipe 32 and the external threaded pipe 12 together and connect the power supply. The device is equipped with an external controller, which is electrically connected to the actuator body 11, the power controller 13, and the gas pump 51 respectively. Manual operation of the external controller can adjust the operating status of the actuator body 11, the power controller 13, and the gas pump 51 respectively. The power controller 13 is an existing device and can control the actuator body 11. The heat-conducting shell 21, the heat-conducting column 22, the isolation cover body 31, and the spiral plate 43 all have relatively high... The device features good thermal conductivity; the isolation cover body 31 and the recessed portion 33 are integrated structures, all of which are existing technologies. When using this device, the operator can adjust the operating status of the power controller 13 via an external controller, which in turn controls the operating status of the actuator body 11. The actuator body 11 can regulate the valve. The external controller can simultaneously start the gas pump 51 and the power controller 13. The heat generated by the power controller 13 can be quickly transferred to the heat-conducting column 22 via the heat-conducting shell 21. Multiple heat-conducting columns 22 of different shapes can then quickly transfer the heat to the isolation cover body 3. The heat is transferred to the spiral plate 43 from various parts of the 1, and then pumped by the gas pump 51 fixed by the mounting base 52. The gas pump 51 delivers the air to the cooling chamber body 41 through the air supply pipe 53. The cooling chamber body 41 is supported by the support column 42 and the spiral plate 43. The spiral plate 43 can divide the space between the cooling chamber body 41, the recess 33, and the internal threaded pipe 32 into a spiral air duct. Air enters the spiral air duct and flows spirally along the air duct, which can quickly remove the heat on the isolation cover body 31 and the spiral plate 43, thereby achieving the purpose of rapid heat dissipation. In the event of an accidental explosion, the heat will be transferred to the isolation cover body. The recessed portion 33 inside 31 will bulge out in the opposite direction under pressure, thereby relieving pressure and improving the explosion-proof effect of the isolation cover body 31. The device can quickly conduct the heat generated by the power controller 13 to the isolation cover body 31 through the heat-conducting shell 21 and the dispersed heat-conducting columns 22. The air is made to flow quickly through the isolation cover body 31 and the spiral plate 43 by the gas pump 51, and the air is made to flow in a spiral by the spiral plate 43, which can quickly dissipate heat from the isolation cover body 31 and the spiral plate 43. The device has a good heat dissipation effect and can effectively prevent the internal temperature of the device from becoming too high, ensuring that the device can work normally.
