Description

Technical Field

[0001] This invention relates to the field of power distribution, and more particularly to a power-on component. Background Technology

[0002] In mines operating within the same area, explosion-proof equipment often shares a single main power cable. When one piece of explosion-proof equipment malfunctions or experiences a power outage, the operating environment is typically explosive. Directly opening the explosion-proof enclosure to turn the power switch on or off could lead to dust or gas explosions. Therefore, workers must shut off the main power cable before opening the explosion-proof enclosure of the malfunctioning equipment and then turning its power switch on or off. This prevents accidents caused by simply opening the enclosure and turning the power switch on or off. However, disconnecting the main power cable to shut off the faulty equipment would simultaneously de-energize other operating equipment, impacting production efficiency. Summary of the Invention

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The power-on component of this invention includes an explosion-proof box 8, a power switch 9, a shift fork assembly 1, and a drive component 2. The explosion-proof box 8 has a receiving space, the power switch 9 is disposed in the receiving space and is adapted to be connected to a power source, the shift fork assembly 1 is disposed in the receiving space, one end of the shift fork assembly 1 is connected to the power switch 9, and the shift fork assembly 1 can swing relative to the explosion-proof box 8 to open or close the power switch 9, one end of the drive component 2 is connected to the shift fork assembly 1, and the other end of the drive component 2 extends out of the explosion-proof box 8.

[0029] Specifically, such as Figures 1 to 5 As shown, the shift fork assembly 1 and the power switch 9 are housed within the containment space. The explosion-proof box 8 isolates the power switch 9 from the underground air, preventing gas or dust explosions during the use of the power switch 9.

[0030] The lower end of the shift fork assembly 1 is connected to the power switch 9. The shift fork assembly 1 can swing clockwise or counterclockwise relative to the explosion-proof box 8 to turn the power switch 9 on or off. The front end of the drive assembly extends into the explosion-proof box 8 and is connected to the shift fork assembly 1 to swing clockwise or counterclockwise. The rear end of the drive assembly extends out of the explosion-proof box 8, allowing the operator to use the drive assembly within the explosion-proof box 8 to swing the shift fork assembly 1 clockwise or counterclockwise to turn the power switch 9 on or off.

[0031] The power-on component of the present invention, by setting up a shift fork assembly 1 and a drive component 2, allows the operator to use the drive component in the explosion-proof box 8 to swing the shift fork assembly 1 clockwise or counterclockwise to turn the power switch 9 on or off, without having to disconnect the main cable, thereby improving the production efficiency of the equipment and thus improving the stability and safety of the equipment in the mine.

[0032] In some embodiments, the driving component 2 includes a rotating rod 21 and a first shift fork, and the shift fork assembly 1 includes a second shift fork, a third shift fork, and a shift fork seat 14. One end of the rotating rod 21 extends out of the explosion-proof box 8, and the other end of the rotating rod 21 is connected to one end of the first shift fork to drive the first shift fork to rotate clockwise or counterclockwise.

[0033] The other end of the first shift fork contacts one end of the second shift fork to drive the second shift fork to rotate clockwise or counterclockwise. The other end of the second shift fork is pivotally connected to the shift fork seat 14. The second shift fork contacts the third shift fork to drive the third shift fork to rotate clockwise or counterclockwise to turn the power switch 9 on or off.

[0034] Specifically, such as Figures 1 to 5 As shown, the rotating rod 21 extends in the front-to-back direction, with its rear end extending out of the explosion-proof enclosure 8. The front end of the rotating rod 21 is connected to the rear end of the first shift fork. The front end of the first shift fork contacts the rear end of the second shift fork, causing the second shift fork to rotate clockwise or counterclockwise. The rear end of the second shift fork contacts the third shift fork, causing the third shift fork to rotate clockwise or counterclockwise to turn the power switch 9 on or off. The upper end of the second shift fork is pivotally connected to the shift fork seat 14, and the upper end of the third shift fork is pivotally connected to the shift fork seat 14. This reduces the resistance of the power-on component to the power switch 9 during automatic tripping, improving the stability and safety of the power-on component.

[0035] The power-on component of this embodiment of the invention, by setting a first shift fork, a second shift fork, and a third shift fork, can turn the power switch 9 on or off by rotating the rear end of the rotating rod 21 to drive the third shift fork to rotate, thereby improving the stability and safety of the power-on component.

[0036] In some embodiments, the first shift fork includes a first shift fork body 22, a first limiting post 221 and a second limiting post 222. One end of the first shift fork body is connected to the rotating rod 21. The first limiting post 221 and the second limiting post 222 are arranged circumferentially at the end of the first shift fork body 22 away from the rotating rod 21. One end of the second shift fork is located between the first limiting post 221 and the second limiting post 222.

[0037] Specifically, such as Figures 1 to 5 As shown, the first limiting post 221 and the second limiting post 222 are cylindrical, and are spaced apart circumferentially on the outer wall of the front end of the first shift fork. The rear end of the second shift fork is located between the first limiting post 221 and the second limiting post 222. The first shift fork rotates to bring either the first limiting post 221 or the second limiting post 222 into contact with the second shift fork, causing the second shift fork to rotate clockwise or counterclockwise.

[0038] The front end of the second shift fork contacts the third shift fork, causing the third shift fork to rotate clockwise or counterclockwise, thereby improving the stability and safety of the power-on assembly.

[0039] In some embodiments, the second shift fork includes a second shift fork body 11, a third limiting post 111, a fourth limiting post 112, and a fifth limiting post 113. One end of the third shift fork is arranged between the first limiting post 221 and the second limiting post 222. The fourth limiting post 112 and the fifth limiting post 113 are arranged circumferentially at the end of the second shift fork body 11 away from the rotating rod 21, and the third shift fork is located between the fourth limiting post 112 and the fifth limiting post 113, and the third shift fork abuts against the fourth limiting post 112 or the fifth limiting post 113.

[0040] Specifically, such as Figures 1 to 5 As shown, the front end of the third limiting post 111 is connected to the body 11 of the second shift fork, and the rear end of the third limiting post 111 is located between the first limiting post 221 and the second limiting post 222. The third shift fork is located between the fourth limiting post 112 and the fifth limiting post 113, and the third shift fork abuts against the fourth limiting post 112 or the fifth limiting post 113. For example, when the power switch 9 is turned on, the third shift fork abuts against the fourth limiting post 112, and when the power switch 9 is turned off, the third shift fork abuts against the fifth limiting post 113, which improves the stability and safety of the power-on component operation.

[0041] In some embodiments, the third shift fork includes a third shift fork body 12 and a shift fork head 13. One end of the third shift fork body 12 is pivotally connected to the shift fork seat 14, and the other end of the third shift fork body 12 is connected to the shift fork head 13.

[0042] The upper end of the third shift fork is pivotally connected to the shift fork seat 14, and the lower end of the third shift fork body 12 is connected to the shift fork head 13. The shift fork head 13 is U-shaped, with its opening facing the power switch 9 and in contact with the power switch 9. By setting the shift fork head 13, the stability and safety of the power-on component are improved.

[0043] Optionally, the power-on assembly also includes a knob 3, which is connected to the end of the rotating rod 21 away from the shift fork assembly 1, i.e., the knob 3 is connected to the rear end of the rotating rod 21. Rotating the knob 3 will cause the rotating rod 21 to rotate, thereby improving the stability and safety of the power-on assembly. Furthermore, the power-on assembly also includes a limiting pad 4, which is fitted onto the rotating rod 21 and located between the explosion-proof box 8 and the knob 3. The limiting pad 4 is suitable for limiting the rotation angle of the knob 3. For example, the knob 3 has a first position and a second position. When the knob 3 is in the first position, the power switch 9 is in the on state. When knob 3 is in the second position, power switch 9 is in the off state. Limiting pad 4 restricts knob 3 from rotating between the first and second positions, preventing excessive rotation angle of knob 3 from causing wear on the power supply components. In addition, the operator can judge the on state of the switch by judging the position of knob 3. Alternatively, when power switch 9 trips automatically, the operator can judge the state of power switch 9 in a timely manner by judging the position of knob 3, thereby improving the stability and safety of the power supply components.

[0044] In some embodiments, the power-on assembly further includes an elastic member 5, one end of which is pivotally connected to the housing of the explosion-proof box 8, and the other end of which is pivotally connected to a third shift fork.

[0045] Specifically, such as Figures 1 to 5As shown, the upper end of the elastic component 5 is pivotally connected to the body of the explosion-proof box 8, and the lower end of the elastic component 5 is pivotally connected to the third shift fork. The third shift fork has a third position and a fourth position. For example, when the third shift fork is in the third position, the power switch 9 is in the on state, and when the third shift fork is in the fourth position, the power switch 9 is in the off state, and the elastic component 5 is in a stretched state. The height of the upper end of the elastic component 5 in the vertical direction is higher than the height of the body 12 of the third shift fork at the upper end. Therefore, when the third shift fork is in the third position and the fourth position, the elastic component 5 will make the third shift fork have a certain resistance when switching between the third position and the fourth position. In turn, the elastic component 5 will make the power on and off knob 3 have a certain resistance, so that the entire power-on assembly is in a tensile state, and each component is in a specific position and will not hang freely, so as to avoid accidental contact by external personnel and cause safety accidents.

[0046] Optionally, the elastic component 5 includes a mounting base 51 and an elastic element 52. The rear end of the mounting base 51 is connected to the housing of the explosion-proof box 8, the front end of the mounting base 51 is pivotally connected to the upper end of the elastic element 52, and the lower end of the elastic element 52 is pivotally connected to the third shift fork. By replacing different mounting bases 51, the elastic element 52 and the third shift fork can be kept parallel in the vertical direction, thereby improving the stability and safety of the powered-on components.

[0047] In some embodiments, the power-on assembly further includes a first limiting member 6 and a second limiting member 7. One end of the first limiting member 6 is connected to the housing of the explosion-proof box 8, and one end of the second limiting member 7 is connected to the housing of the explosion-proof box 8. The first limiting member 6 and the second limiting member 7 are adapted to limit the rotation angle of the third shift fork.

[0048] Specifically, such as Figures 1 to 5 As shown, the rear end of the first limiting member 6 is connected to the explosion-proof box 8, and the rear end of the second limiting member 7 is connected to the box. The first limiting member 6 and the second limiting member 7 are adapted to limit the rotation angle of the third shift fork. That is, the first limiting member 6 and the second limiting member 7 limit the rotation range of the third shift fork between the third position and the fourth position, thereby improving the stability and safety of the power-on assembly.
