Description

Technical Field

[0001] The invention relates to the technical field of supporting facilities for electric power equipment, and in particular to an anti-accidental collision device for a separation switch of a high- and low-voltage distribution cabinet. Background Art

[0002] As the name implies, high and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led to low voltage distribution cabinets. The low voltage distribution cabinets are connected to the distribution boards, control boxes and switch boxes of various power users. The equipment in the cabinets is a distribution device that meets the design functional requirements by assembling some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices into one.

[0003] Common high and low voltage distribution cabinets are equipped with separation gates, which are usually manually cut off in order to quickly cut off the power supply in case of emergencies. However, the separation gates are usually directly set outside without any protective devices, which makes it easy for people to accidentally touch the separation gates when performing other operations on the distribution cabinets, thus causing unnecessary impacts. In addition, the separation gates are equipped with simple protective devices, which are easy to cause the protective devices themselves to fall off when accidentally touched;

[0004] In the prior art, technicians have set a shell or cover outside the separation switch to protect the knife switch to prevent the knife switch from accidentally touching the outside and causing unexpected opening and closing. However, since the switch or knife switch is mostly fixedly installed in the cabinet, the additional protective cover is generally not fixedly installed on the cabinet, which will cause inconvenience in operating or repairing other components. Therefore, when the shell or cover falls, it will accidentally touch the switch knife switch, or when the cover is touched after the shell during other maintenance or repair, or when the shell or cover needs to be temporarily removed, it will accidentally touch the switch knife switch due to improper operation or mistakes. When the external vibration is large, such as being subjected to a large impact, the shell or cover cannot reduce the impact of the vibration on the separation switch. At this time, the separation switch is prone to unexpected opening and closing under vibration. Therefore, the temporary protective shell in the prior art has inevitable disadvantages, which in turn affects the safety of power operations;

[0005] Therefore, it is necessary to invent a device for preventing accidental collision of a high and low voltage distribution cabinet separation gate. Summary of the invention

[0006] To this end, the present invention provides an anti-accidental collision device for the separation gates of high and low voltage distribution cabinets. By adding an external safety device and a protective box, the rotating rod in the safety device is located inside the protective box. When the safety device is in operation, external force will not affect the opening and closing of the separation gate. When the safety device is not working, the separation gate can be opened and closed manually to solve the problem that the existing anti-accidental collision device is easily affected by the external environment.

[0007] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: an anti-accidental collision device for a separation gate of a high- and low-voltage distribution cabinet, comprising a safety device, a protection box and a separation gate, wherein the safety device and the separation gate are both located inside the protection box, and the safety device comprises a starting component: and further comprises: a self-locking component connected to the starting component;

[0008] The self-locking assembly includes a fixed plate, the bottom of which is fixedly connected to the inner wall of the protective box, a limit rod is fixedly installed on one side of the fixed plate, a damping bearing is provided on the other side of the fixed plate, a counterweight block is provided on one side of the fixed plate, the counterweight block is rotatably connected to the fixed plate through the damping bearing, and first fixing bolts are provided at both ends of the counterweight block;

[0009] The self-locking assembly also includes an arched transmission plate, one side of the arched transmission plate is fixedly connected to the outer side wall of the counterweight block by a first fixing bolt, one side of the arched transmission plate is provided with a first buckle, a rotating plate is provided on the outer side of the arched transmission plate, one side of the rotating plate is provided with a second buckle, and the other side of the rotating plate is provided with a third buckle, a hard spring is clamped on the third buckle, and the other end of the hard spring is clamped with the first buckle;

[0010] The connecting parts of the rotating plate, the counterweight block and the fixed plate are provided with second fixing bolts, and are connected by the second fixing bolts. The fixed plate is fixedly connected with the second fixing bolts, and the rotating plate and the counterweight block are both rotatably connected with the second fixing bolts.

[0011] Preferably, the starting assembly includes a mounting shell, and the mounting shell is provided with two groups. The inner walls of the two groups of mounting shells are fixedly connected with the same limiting column, the outer walls of the limiting column are rotatably connected with a swivel seat, the outer walls on both sides of the swivel seat are rotatably connected with the inner walls of the two groups of mounting shells, two groups of fourth clips are provided on one side of the bottom of the swivel seat, the two groups of fourth clips are symmetrically arranged, and a rotating rod is fixedly installed on the top of the swivel seat.

[0012] Preferably, the inner wall of the protection box is provided with a separation gate installation area, the separation gate is rotatably connected to the side wall of the separation gate installation area, the inner wall of the protection box is also provided with a safety rod installation area, and the two groups of outer walls of the installation shell are fixedly connected to the inner wall of the safety rod installation area.

[0013] Preferably, a force-bearing column is provided at the end of the separation gate, the force-bearing column is clamped with the second buckle, the limiting rod is clamped with two groups of the fourth buckles, and the end of the rotating rod is rotatably connected to the side wall of the arched transmission plate.

[0014] The beneficial effects of the present invention are:

[0015] 1. By pushing the rotating rod upward (applying a continuous force to the rotating rod), the fourth buckle on the rotating seat connected to the rotating rod is disengaged from the limit rod. As the rotating rod rotates upward, based on the lever principle, the arched transmission plate connected to the end of the rotating rod is subjected to a downward pressure at the connection point. Therefore, the other side of the arched transmission plate and the counterweight block rotate downward around the second fastening bolt. At this time, the first buckle on the arched transmission plate applies pressure to the hard spring, thereby forcing the hard spring to drive the rotating plate to rotate downward around the second fastening bolt, so that the second buckle on the rotating plate is disengaged from the force column on the separation gate. At this time, the separation gate can be closed to avoid the separation gate being closed due to external factors.

[0016] 2. When it is necessary to open the separation gate and put the separation gate in an anti-accidental collision state, the technical personnel in this field push the rotating rod downward to make the fourth buckle on the rotating seat connected to the rotating rod engage with the limit rod. At this time, since the rotating rod rotates downward, based on the lever principle, the bow-shaped transmission plate connected to the end of the rotating rod is subjected to an upward thrust at the connection point. Therefore, the other side of the bow-shaped transmission plate and the counterweight block both rotate upward around the second tightening bolt. At this time, the hard spring drives the rotating plate to rotate upward around the second tightening bolt, so that the second buckle on the rotating plate is combined with the force column on the separation gate. At the same time, under the action of the elastic force of the hard spring, the second buckle always presses down the force column, making the separation gate difficult to open.

DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] See attached Figure 1-8 The present invention provides a device for preventing accidental collision of a separation gate of a high- and low-voltage power distribution cabinet, comprising a safety device 100, a protection box 200 and a separation gate 300, wherein the safety device 100 and the separation gate 300 are both located inside the protection box 200, and the safety device 100 comprises a starting component 140: and further comprises: a self-locking component 110 connected to the starting component 140;

[0028] The self-locking assembly 110 includes a fixed plate 111, the bottom of the fixed plate 111 is fixedly connected to the inner wall of the protection box 200, the protection box 200 provides support for the fixed plate 111, a limit rod 112 is fixedly installed on one side of the fixed plate 111, and a damping bearing 113 is provided on the other side of the fixed plate 111. The counterweight 114 is rotatably connected to the fixed plate 111 through the damping bearing 113, which can prevent the counterweight 114 from angularly deflecting from the fixed plate 111 under the action of gravity. A counterweight 114 is provided on one side of the fixed plate 111, and the counterweight 114 is rotatably connected to the fixed plate 111 through the damping bearing 113. First fixing bolts 115 are provided at both ends of the counterweight 114;

[0029] The self-locking assembly 110 also includes an arched transmission plate 116, one side of which is fixedly connected to the outer side wall of the counterweight 114 by a first fixing bolt 115. The first fixing bolt 115 plays a supporting role at the connection between the arched transmission plate 116 and the counterweight 114, so that they form a whole. A first buckle 117 is provided on one side of the arched transmission plate 116, a rotating plate 118 is provided on the outer side of the arched transmission plate 116, a second buckle 119 is provided on one side of the rotating plate 118, and a third buckle 120 is provided on the other side of the rotating plate 118. A hard spring 130 is clamped on the third buckle 120, and the other end of the hard spring 130 is clamped with the first buckle 117. Specifically, the elastic modulus of the hard spring 130 is large, that is, it can only produce a small deformation when subjected to a large force;

[0030] The second fixing bolt 150 is provided at the connection between the rotating plate 118, the counterweight block 114 and the fixed plate 111, and the rotating plate 118, the counterweight block 114 and the fixed plate 111 are connected by the second fixing bolt 150. The second fixing bolt 150 connects the rotating plate 118, the counterweight block 114 and the fixed plate 111 together to form a whole. The fixed plate 111 is fixedly connected to the second fixing bolt 150, and the rotating plate 118 and the counterweight block 114 are both rotatably connected to the second fixing bolt 150. Specifically, by pushing the rotating rod 145 upward (applying a force to the rotating rod 145), the rotating plate 118, the counterweight block 114 and the fixed plate 111 are connected to the second fixing bolt 150. The fourth buckle 144 on the rotating seat 143 connected to the rotating rod 145 is separated from the limiting rod 112. As the rotating rod 145 rotates upward, based on the lever principle, the arched transmission plate 116 connected to the end of the rotating rod 145 is subjected to a downward pressure at the connection point. Therefore, the other side of the arched transmission plate 116 and the counterweight 114 rotate downward around the second fastening bolt 150. At this time, the first buckle 117 on the arched transmission plate 116 applies pressure to the hard spring 130, thereby forcing The hard spring 130 drives the rotating plate 118 to rotate downward around the second fastening bolt 150, so that the second buckle 119 on the rotating plate 118 is disengaged from the force-bearing column 310 on the separation gate 300. At this time, the separation gate 300 can be closed. Conversely, by pushing the rotating rod 145 downward, the fourth buckle 144 on the rotating seat 143 connected to the rotating rod 145 is engaged with the limiting rod 112. At this time, due to the downward rotation of the rotating rod 145, based on the lever principle, the arched transmission plate 116 connected to the end of the rotating rod 145 is The connection is subjected to an upward thrust, so the other side of the bow-shaped transmission plate 116 and the counterweight block 114 both rotate upward around the second tightening bolt 150. At this time, the hard spring 130 drives the rotating plate 118 to rotate upward around the second tightening bolt 150, so that the second buckle 119 on the rotating plate 118 is combined with the force-bearing column 310 on the separation gate 300. At the same time, under the action of the elastic force of the hard spring 130, the second buckle 119 always presses down the force-bearing column 310, making the separation gate 300 difficult to open.

[0031] Furthermore, the starting assembly 140 includes a mounting shell 141, and the mounting shell 141 is provided with two groups. The inner side walls of the two groups of mounting shells 141 are fixedly connected with the same limiting column 142. The two groups of mounting shells 141 provide mounting positions for the limiting column 142. The outer side walls of the limiting column 142 are rotatably connected with a rotating seat 143. The limiting column 142 provides support for the rotating seat 143. The outer walls on both sides of the rotating seat 143 are rotatably connected with the inner side walls of the two groups of mounting shells 141. Two groups of fourth buckles 144 are provided on one side of the bottom of the rotating seat 143. The two groups of fourth buckles 144 are symmetrically arranged. The fourth buckle 144 of the group is engaged with the limit rod 112, so that the bow-shaped transmission plate 116 is difficult to rotate due to the influence of gravity. A rotating rod 145 is fixedly installed on the top of the rotating seat 143. Specifically, by pushing the rotating rod 145 upward (applying a continuous force to the rotating rod 145), the fourth buckle 144 on the rotating seat 143 connected to the rotating rod 145 is disengaged from the limit rod 112. As the rotating rod 145 rotates upward, based on the lever principle, the bow-shaped transmission plate 116 connected to the end of the rotating rod 145 is subjected to a downward pressure at the connection.

[0032] Furthermore, a separation gate installation area 210 is provided on the inner wall of the protection box 200, and the separation gate 300 is rotatably connected to the side wall of the separation gate installation area 210. A bumper installation area 220 is also provided on the inner wall of the protection box 200. The outer walls of the two groups of mounting shells 141 are fixedly connected to the inner wall of the bumper installation area 220, and the rotating rod 145 is located inside the bumper installation area 220 to prevent external factors from contacting the bumper installation area 220.

[0033] Furthermore, a force-bearing column 310 is provided at the end of the separation gate 300, and the force-bearing column 310 is engaged with the second buckle 119. When in the safety state, the second buckle 119 always applies downward pressure to the force-bearing column 310, thereby making it difficult for the separation gate 300 to rotate downward. The limiting rod 112 is engaged with the two groups of fourth buckles 144. By engaging the limiting rod 112 with the two groups of fourth buckles 144, the separation gate 300 is in the safety state, and the end of the rotating rod 145 is rotatably connected to the side wall of the bow-shaped transmission plate 116.

[0034] The use process of the present invention is as follows: a person skilled in the art pushes the rotating rod 145 upward (applies a continuous force to the rotating rod 145) to disengage the fourth buckle 144 on the rotating seat 143 connected to the rotating rod 145 from the limiting rod 112. As the rotating rod 145 rotates upward, based on the lever principle, the arched transmission plate 116 connected to the end of the rotating rod 145 is subjected to a downward pressure at the connection point. Therefore, the other side of the arched transmission plate 116 and the counterweight block 114 both rotate downward around the second tightening bolt 150. At this time, the first buckle 117 on the arched transmission plate 116 applies pressure to the hard spring 130, thereby forcing the hard spring 130 to drive the rotating plate 118 to rotate downward around the second tightening bolt 150, so that the second buckle 119 on the rotating plate 118 is disengaged from the force-bearing column 310 on the separation gate 300. At this time, the separation gate 300 can be closed.

[0035] When it is necessary to open the separation gate 300 and put the separation gate 300 in an anti-accidental collision state, the technicians in this field push the rotating rod 145 downward to make the fourth buckle 144 on the rotating seat 143 connected to the rotating rod 145 engage with the limiting rod 112. At this time, due to the downward rotation of the rotating rod 145, based on the lever principle, the bow-shaped transmission plate 116 connected to the end of the rotating rod 145 is subjected to an upward thrust at the connection point. Therefore, the other side of the bow-shaped transmission plate 116 and the counterweight block 114 both rotate upward around the second tightening bolt 150. At this time, the hard spring 130 drives the rotating plate 118 to rotate upward around the second tightening bolt 150, so that the second buckle 119 on the rotating plate 118 is combined with the force column 310 on the separation gate 300. At the same time, under the action of the elastic force of the hard spring 130, the second buckle 119 always presses down the force column 310, thereby making the separation gate 300 difficult to be opened.

[0036] The above is only a preferred embodiment of the present invention. Any person skilled in the art may modify the present invention by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention shall fall within the scope of protection claimed by the present invention.
