Description

Technical Field

[0001] The present invention relates to the technical field of safety protection equipment, and particularly to an insulating baffle. Background Art

[0002] The handcart-type switch cabinet is widely used in substations. Due to work needs, maintenance personnel often need to enter the circuit breaker chamber of the switch cabinet. Since the static contact on the bus side of the circuit breaker chamber is energized, although the switch cabinet body is equipped with a static contact flap, the flap is prone to insufficient shielding area or jamming, resulting in incomplete closure. The baffle cannot completely cover the metal plate with static contacts inside, and some baffles do not have a locking device. If the maintenance personnel accidentally open the baffle, there is a risk that the maintenance personnel are too close to the energized static contact or accidentally touch the energized equipment during operation. The conventional safety measure is that the entire section of the bus where the switch cabinet to be repaired is located needs to be accompanied by power outage for maintenance. Although this method can ensure the safety of the operating personnel, it also expands the power outage scope, and other switch cabinets on this section of the bus also need to be accompanied by power outage, affecting the power supply reliability.

[0037] Embodiment 1:

[0038] As Figures 1 to 4 shown, this embodiment provides an insulating baffle, which is used to be installed inside the cabinet 100. There is a metal plate 101 inside the cabinet 100, and a static contact is arranged inside the metal plate 101. This insulating baffle can cover the surface of the metal plate 101 and completely block the static contact inside the metal plate 101, thereby preventing maintenance personnel from accidentally touching the metal plate 101 and causing electric shock hazards.

[0039] See Figure 1, the insulating baffle includes an insulating plate 1, a connecting component 2, an insulating rod 3, and an adsorption component 4. The connecting component 2 is provided on the insulating plate 1; the insulating rod 3 is detachably connected to the connecting component 2; the adsorption component 4 is provided on the insulating plate 1, and the adsorption component 4 can adsorb on the metal plate 101 to fix the insulating plate 1 on the metal plate 101. The insulating plate 1 can block the static contact to prevent maintenance personnel from accidentally touching the metal plate 101 and causing an electric shock hazard when working inside the cabinet 100.

[0040] See Figure 2 , in the insulating baffle of this embodiment, the connecting component 2 includes a circular tube 21 and two half-rings 22. The circular tube 21 is provided on the insulating plate 1, and the two half-rings 22 are provided inside the circular tube 21. The openings of the two half-rings 22 are arranged opposite to each other, and the two half-rings 22 enclose a circular ring shape. The two half-rings 22 are provided with internal threads, and the insulating rod 3 is provided with external threads. The external threads of the insulating rod 3 can cooperate with the internal threads of the two half-rings 22. The insulating rod 3 passes through and is threadedly connected to the half-ring 22 to fix the insulating rod 3 to the insulating plate 1 through the connecting component 2.

[0041] In order to guide the insulating rod 3 to better pass through the inside of the half-ring 22 in the circular tube 21, one end of the half-ring 22 away from the insulating plate 1 is provided with an inclined surface that gradually slopes downward from the outside to the center. Two limiting pieces 24 are arranged on the upper surface of the half-ring 22, and the two limiting pieces 24 enclose a circular ring shape. The top end of the inclined surface of the half-ring 22 is correspondingly connected to the inner side of the limiting piece 24, and the bottom end of the inclined surface of the half-ring 22 is correspondingly connected to the inner side surface of the clamping frame 23. When the insulating rod 3 enters the connecting component 2, the arrangement of the limiting piece 24 and the inclined surface of the half-ring 22 can play a guiding role.

[0042] In order to better fix the insulating rod 3 to the connecting component 2, the connecting component 2 further includes two clamping frames 23. Through grooves 211 are provided on both sides of the circular tube 21, and the two clamping frames 23 pass through the circular tube 21 through the through grooves 211. One end of the clamping frame 23 is connected to the insulating plate 1 through an elastic component 5, and the other end is fixedly connected to the bottom surface of the half-ring 22. The clamping frame 23 is used to clamp the insulating rod 3, and the elastic component provides the clamping force.

[0043] See Figure 3, in the insulating baffle of this embodiment, the elastic component 5 includes a pressing plate 51 and a spring 52. The insulating plate 1 is provided with a strip groove 11. The elastic component 5 is arranged in the strip groove 11. One end of the pressing plate 51 is connected to the clamping frame 23, the other end of the pressing plate 51 is connected to one end of the spring 52, and the other end of the spring 52 is connected to the side wall of the strip groove 11 away from the pressing plate 51. The compression and elongation of the spring 52 can drive the pressing plate 51 to move in the strip groove 11. When the spring 52 is compressed, it drives the two clamping frames 23 to move away from each other, and the two clamping frames 23 move to a position away from the insulating rod 3, so that the insulating rod 3 can enter the inside of the two clamping frames 23. When the spring 52 extends, it drives the two clamping frames 2 to move towards each other, and the two clamping frames 23 move closer to the central axis of the circular tube 21, and can restore the initial state where the connecting component 2 is not connected to the insulating rod 3.

[0044] Specifically, internal threads are provided on the inner sides of both the clamping frame 23 and the half ring 22, and the clamping frame 23 and the half ring 22 can be threadedly connected to the insulating rod 3. When installing the insulating rod 3, one end of the insulating rod 3 is aligned with the circle formed by the inside of the two limiting pieces 24, so that the insulating rod 3 is buckled inside the limiting pieces 24. Rotate the insulating rod 3, so that under the guidance of the inclined surface of the half ring 22, the external thread of the insulating rod 3 is sequentially matched with the internal threads of the half ring 22 and the clamping frame 23. The half ring 22 moves towards the direction close to the circular tube 21, driving the clamping frame 23 to move and compress the elastic component 5. The reaction force generated by the compression of the elastic component 5 can make the clamping frame 23 clamp the insulating rod 3 more tightly, so as to improve the connection stability between the insulating rod 3 and the insulating plate 1.

[0045] The adsorption component 4 includes a through rod 41 and a suction cup 42 connected to the through rod 41. The suction cup 42 is used to adsorb the metal plate 101. The insulating plate 1 is provided with a sliding groove 12, and the through rod 41 is slidably connected to the sliding groove 12, so that the adsorption component 4 can move along the sliding groove 12 to adjust the position, so as to be suitable for installation on different metal plates 101.

[0046] Specifically, the adsorption component 4 further includes a seal 43. In this embodiment, the seal 43 is a nut. The through rod 41 is communicated with the suction cup 42. One end of the through rod 41 is provided with a leakage hole 411, and the seal 43 is sleeved at the leakage hole 411 of the through rod 41. When the seal 43 is separated from the leakage hole 411, the suction cup 42 can be communicated with the outside through the leakage hole 411, so that the suction cup 42 is separated from the adsorption of the metal plate 101. When the seal 43 blocks the leakage hole, the suction cup 42 is in a sealed state, so that the suction cup 42 and the metal plate 101 are adsorbed.

[0047] To improve the installation stability between the insulating plate 1 and the metal plate 101, the insulating baffle in this embodiment further includes a clamping assembly 6. The clamping assembly 6 is connected to the pressing plate 51. A clamping groove 412 is provided at the position where the through rod 41 is connected to the suction cup 42. The clamping groove 412 can communicate the suction cup 42 with the outside, so that the suction cup 42 is separated from the adsorption on the metal plate 101. The clamping of the clamping assembly 6 with the clamping groove 412 can seal the suction cup 42, so that the suction cup 42 can adsorb on the metal plate 101.

[0048] Specifically, the clamping assembly 6 includes a cross bar 61 and a clamping member 62. The clamping member 62 is arranged at one end of the cross bar 61 close to the adsorption assembly 4. The other end of the cross bar 61 is connected to the pressing plate 51. The movement of the pressing plate 51 can drive the movement of the clamping assembly 6. The clamping member 62 is used to seal the clamping groove 412.

[0049] The clamping groove 412 is arranged at one end of the through rod 41 close to the suction cup 42, and a leakage hole 411 is arranged at the end of the through rod 41 far from the suction cup 42. When the vibration of the cabinet body 100 drives the vibration of the insulating plate 1, resulting in the leakage of air through the leakage hole 411 between the sealing member 43 and the through rod 41, since the clamping member 62 is clamped in the clamping groove 412, the inside of the suction cup 42 can always be in a sealed state, thereby improving the installation stability between the insulating plate 1 and the metal plate 101. To ensure the insulation of the insulating baffle, the clamping assembly 6 and the adsorption assembly 4 are respectively made of insulating materials.

[0050] See Figure 4 , a plurality of connecting columns 1011 are arranged on the metal plate 101. The connecting columns 1011 are made of insulating materials. The insulating plate 1 further includes a plurality of through holes 13. The plurality of connecting columns 1011 pass through the plurality of through holes 13, which can position the insulating plate 1 on the metal plate 101, ensure the accurate installation position of the insulating plate 1, and can block the metal plate 101 and the live static contact located inside the metal plate 101.

[0051] When installing the insulating baffle, align the insulating rod 3 with the limiting piece 24, and through the guiding of the inclined surface of the semi-ring 22, pass through and thread-connect the insulating rod 3 to the connecting assembly 2, so that the insulating rod 3 is connected to the insulating plate 1. The staff holds the insulating rod 3, aligns the plurality of through holes 13 of the insulating plate 1 with the plurality of connecting columns 1011, and pushes the insulating plate 1 along the direction of the metal plate 101, so that the suction cup 42 contacts the metal plate 101. Take out the insulating rod 3, press the through rod 41 so that the suction cup 42 adsorbs on the metal plate 101, and turn the sealing member 43 so that the sealing member 43 fits the surface of the insulating plate 1, thereby restricting the axial displacement of the through rod 41, keeping the suction cup 42 in the adsorbed state on the metal plate 101, and sealing the leakage hole 411 on the through rod 41. Move the through rod 41 along the sliding groove 12, so that the clamping groove 412 of the through rod 41 is clamped by the clamping member 62 to seal the top of the suction cup 42 and ensure the adsorption effect between the suction cup 42 and the metal plate 101.

[0052] When removing the insulating baffle, insert the insulating rod 3 and threadedly connect it to the two half-rings 22 and the two clamping frames 23 in sequence. The movement of the half-ring 22 drives the movement of the clamping frame 23, which in turn drives the movement of the pressing plate 51. The movement of the pressing plate 51 can drive the movement of the clamping component 6, enabling the clamping member 62 to disengage from the through rod 41 and the suction cup 42 to disengage from the adsorption of the metal plate 101. The staff holds the insulating rod 3 and can take out the insulating baffle in the direction away from the metal plate 101.

For the sake of simplicity, only the differences between Embodiment 2 and Embodiment 1 are described. The difference lies in that the seal 43 is a plug, and the plug can be in interference fit with the leakage hole 411 to block the leakage hole 411 on the side wall of the through rod 41.
