Description

Technical Field

[0001] This utility model relates to the field of relay voltage plate monitoring technology, specifically to a spliced ​​relay protection pressure plate monitoring device. Background Technology

[0002] The relay protection plate, also called the protection connector or trip plate, is the bridge and link between the protection device and the external wiring. It is related to whether the protection function and the action output can play a normal role.

[0003] Chinese Patent Publication No. CN218002562U discloses an intelligent monitoring device for substation pressure plates, comprising a base. A first knob and a second knob are fixedly mounted near the top and bottom of the front face of the base, respectively. A pressure plate connecting piece is fixedly sleeved on the outer wall of the first knob. An arc-shaped groove is fixedly formed at the end of the pressure plate connecting piece away from the first knob. A clamp is fixedly mounted on the outer wall of the middle portion of the pressure plate connecting piece. A hollow groove is fixedly formed at the inner end of the clamp. A conductive piece is fixedly mounted at the inner end of the hollow groove. Two return springs are fixedly connected to one side of the conductive piece. Connectors are fixedly connected to the ends of the two return springs away from the conductive piece. This utility model has a reasonable overall structural design. The indicator light can quickly and accurately help testing personnel determine the engagement / disengagement status of the pressure plate, reducing testing difficulty and improving efficiency, thus possessing practicality.

[0004] In the aforementioned prior art, the indicator light can be controlled to turn on or off based on the change in the activation / deactivation state of the pressure plate, making it convenient for testing personnel to check. However, when installing relay protection pressure plates, many relay protection pressure plates are usually set on a base plate, and the distance between adjacent relay protection pressure plates is relatively close. In addition, the monitoring device is fixedly set to the base plate. If one of the monitoring devices malfunctions, it is not convenient to disassemble, repair, or replace it individually. During repair, adjacent pressure plates or monitoring devices are also prone to interference. Utility Model Content

[0005] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a spliced ​​relay protection pressure plate monitoring device to solve some or all of the problems in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A modular relay protection pressure plate monitoring device includes:

[0008] Relay protection pressure plate;

[0009] The indicator is placed on the relay protection pressure plate to generate light for warning purposes.

[0010] A triggering mechanism is arranged on the reminder mechanism and the relay protection pressure plate to control the reminder mechanism to light up and turn off according to the state of the relay protection pressure plate;

[0011] The triggering mechanism includes a fixing structure for assembling and disassembling the relay protection pressure plate and a linkage structure for switching on and off in accordance with the activation and deactivation reminder mechanism of the relay protection pressure plate.

[0012] Preferably, the relay protection pressure plate includes:

[0013] Two connecting posts;

[0014] Knob 1 and Knob 2 are respectively located at one end of the two connecting posts;

[0015] The pressure plate connecting piece is movably sleeved on the two connecting posts, with one end of the pressure plate connecting piece being open.

[0016] An insulating block is placed on the pressure plate connecting piece and is used to turn the pressure plate connecting piece so that it flips.

[0017] Preferably, the reminder mechanism includes:

[0018] Mounting box;

[0019] The mounting frame is glued to the mounting box;

[0020] Both the circuit board and the battery are located on one side of the mounting frame;

[0021] The indicator light and the switch are both electrically connected to the circuit board, with the indicator light located on one side of the circuit board.

[0022] A transparent panel is placed on the inner wall of the mounting box, located on one side of the indicator light;

[0023] The battery is electrically connected to the circuit board to supply power to the circuit board.

[0024] Preferably, the fixing structure includes:

[0025] The positioning frame is movably fitted onto the insulating block and arranged on one side of the mounting box;

[0026] The fixing screw passes through the positioning frame and is threaded into the inside of the insulating block.

[0027] Preferably, the linkage structure includes:

[0028] The limiting collar is movably fitted onto knob one;

[0029] A pull rope is placed on one side of the limiting collar;

[0030] The extrusion plate is slidably installed inside the mounting box, and the extrusion plate is arranged at one end of the pull rope;

[0031] The mounting plate is placed inside the mounting box;

[0032] A guide assembly, arranged on the extrusion plate, is used to limit the direction of movement of the extrusion plate;

[0033] Support components, arranged on the pull rope, provide support for the pull rope;

[0034] The mounting plate is arranged on one side of the switch, and the switch corresponds to the pressing plate.

[0035] Preferably, the guide component includes:

[0036] The guide slide plate is slidably mounted inside the mounting plate and arranged on one side of the extrusion plate;

[0045] This invention, when the pressure plate connecting piece is pushed to disconnect one end from the connecting post, causes the mounting box to flip, resulting in the pull rope being pulled by the limiting collar, which in turn moves the squeezing plate. The squeezing plate then squeezes and triggers the switch, illuminating the indicator light to alert the operator. This allows the operator to quickly identify the disconnected pressure plate connecting piece among the many protective pressure plates. Conversely, when the pressure plate connecting piece is pushed to reconnect, the spring pushes the squeezing plate away from the switch, turning off the indicator light. Thus, the indicator light can be switched on and off according to the pressure plate's on / off state, allowing the operator to promptly check and determine the status of the protective pressure plates.

[0046] This utility model, through its splicing design, allows for easy removal of the mounting box from the pressure of the knob when the mounting box is damaged. Rotating the retaining screw releases it from the insulating block, thus releasing the connection restriction on the mounting box. At this point, pushing the positioning frame and pulling the limiting collar from the knob allows the mounting box to be separated from the relay protection pressure plate, facilitating the replacement of the damaged mounting box. Furthermore, the mounting frame is secured with adhesive, which can be heated with a hot air gun and then pulled out, causing the circuit board and indicator light to separate from the mounting box, allowing for the individual replacement of damaged components within the mounting box.

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0056] Example 1:

[0057] like Figures 1 to 5 As shown, this utility model provides a spliced ​​relay protection pressure plate monitoring device, including: a relay protection pressure plate 1, the relay protection pressure plate 1 including two connecting posts 101, a knob 102 and a knob 103 arranged at one end of the two connecting posts 101, a pressure plate connecting piece 104 movably sleeved on the two connecting posts 101, one end of the pressure plate connecting piece 104 being open, and an insulating block 105 arranged on the pressure plate connecting piece 104 for turning the pressure plate connecting piece 104 to rotate it.

[0058] To facilitate checking whether the protection pressure plate is in the open state, a reminder mechanism for generating light is arranged on the relay protection pressure plate 1. A trigger mechanism is arranged on the reminder mechanism and the relay protection pressure plate 1 to control the reminder mechanism to light up and turn off according to the state of the relay protection pressure plate 1. The trigger mechanism includes a linkage structure for driving the reminder mechanism to switch on and off in accordance with the activation and deactivation of the relay protection pressure plate 1.

[0059] The reminder mechanism includes a mounting box 2 and a mounting frame 201 adhered to the mounting box 2. A circuit board 202 and a battery 203 are arranged on one side of the mounting frame 201. An indicator light 204 and a switch 205 are electrically connected to the circuit board 202. The indicator light 204 is arranged on one side of the circuit board 202. A transparent plate 206 is arranged on the inner wall of the mounting box 2, located on one side of the indicator light 204. The battery 203 is electrically connected to the circuit board 202 to supply power to the circuit board 202. When the switch 205 is triggered, the switch 205 transmits a signal to the circuit board 202, which controls the indicator light 204 to light up. The light generated by the indicator light 204 can pass through the transparent plate 206 so that the staff can quickly see which relay protection pressure plates 1 are in the open state.

[0060] The linkage structure includes a limiting collar 302 movably sleeved on the knob 102, a pull rope 303 arranged on one side of the limiting collar 302, a pressing plate 304 slidably installed inside the mounting box 2, the pressing plate 304 arranged at one end of the pull rope 303, a mounting plate 305 arranged inside the mounting box 2, a guide component arranged on the pressing plate 304 to limit the movement direction of the pressing plate 304, a support component arranged on the pull rope 303 to provide support for the pull rope 303, and the mounting plate 305 arranged on one side of the switch 205. The switch 205 corresponds to the pressing plate 304. When the mounting box 2 is flipped, the limiting collar 302 will pull the pull rope 303. The moving pull rope 303 can drive the pressing plate 304 to move. When the pressing plate connecting piece 104 is disconnected from the connecting post 101, the pressing plate 304 will be squeezed and the switch 205 will be triggered.

[0061] Specifically, the guide assembly includes a guide slide plate 306 slidably mounted inside the mounting plate 305 and arranged on one side of the extrusion plate 304, and a spring 307 slidably sleeved on the guide slide plate 306. The spring 307 is arranged between the extrusion plate 304 and the mounting plate 305 and is used to drive the extrusion plate 304 to move and reset. The moving pull rope 303 can drive the extrusion plate 304 to move, so that the extrusion plate 304 squeezes the spring 307 and drives the guide slide plate 306 to move inside the mounting plate 305, so as to prevent the extrusion plate 304 from deviating. When the pressure plate connecting piece 104 is re-inserted, the spring 307 in the compressed state will push the extrusion plate 304 to reset.

[0062] Specifically, the support assembly includes a fixed plate 308 arranged on the inner wall of the mounting box 2, and a pulley 309 rotatably installed on one side of the fixed plate 308. The pulley 309 is in contact with the pull rope 303. By setting the pulley 309, the pull rope 303 and the extrusion plate 304 can be kept in a perpendicular state.

[0063] The linkage structure also includes an adjusting screw hole 310 inside the limiting collar 302 and a pressing screw 311 threaded in the adjusting screw hole 310 for pressing the knob 102. The pressing screw 311 contacts the outer surface of the knob 102. By rotating the pressing screw 311, it can move within the adjusting screw hole 310 and press against the outer surface of the knob 102, thereby fixing the limiting collar 302 on the knob 102 and preventing it from loosening.

[0064] Example 2:

[0065] Based on Example 1, in order to facilitate the individual disassembly and repair or replacement of damaged components, a fixing structure for disassembly and assembly with the relay protection pressure plate 1 is provided.

[0066] The fixing structure includes a positioning frame 3 that is movably sleeved on the insulating block 105 and arranged on one side of the mounting box 2, and a fixing screw 301 that passes through the positioning frame 3 and is threaded inside the insulating block 105. The fixing screw 301 is unscrewed from the insulating block 105 and the positioning frame 3, and then the pressing screw 311 is rotated. When the pressing screw 311 rotates, it can move by cooperating with the adjusting screw hole 310, so that the pressing screw 311 is released from the pressure on the knob 102. At this time, the limiting collar 302 can be pulled out from the knob 102, and then the positioning frame 3 is pushed to push it out from the insulating block 105, so that the mounting box 2 can be separated.

[0067] Working principle:

[0068] Pulling the mounting box 2 moves the positioning frame 3, which in turn causes the pressure plate connecting piece 104 to flip via the insulating block 105, disengaging it from one of the connecting posts 101. Simultaneously, the mounting box 2, while flipping, pulls the pull rope 303 using the limiting collar 302. The moving pull rope 303, through friction with the pulley 309, causes the pulley 309 to rotate on the fixed plate 308. The pulley 309 ensures the pull rope 303 remains perpendicular to the pressing plate 304. The continuously moving pull rope 303 moves the pressing plate 304, causing it to... The guide slide 306 moves inside the mounting plate 305 to prevent the compression plate 304 from shifting. The continuously moving compression plate 304 compresses the spring 307, storing energy. This disconnects the pressure plate connecting piece 104 from the connecting post 101, causing the compression plate 304 to press and trigger the switch 205. The switch 205 transmits a signal to the circuit board 202, which controls the indicator light 204 to illuminate. Both the circuit board 202 and the indicator light 204 are powered by the battery 203. The light emitted by the indicator light 204 can pass through the transparent plate 206. When the pressure plate connecting piece is reinserted... At position 104, the pressure plate connecting piece 104 is flipped to reset, thereby moving the mounting box 2 to reset. Simultaneously, the compressed spring 307 pushes the pressing plate 304 to reset, releasing it from the pressure on the switch 205, thus turning off the indicator light 204. This allows staff to quickly identify which relay protection pressure plates 1 are in the off state. To disassemble the mounting box 2, simply unscrew the fixing screw 301 from the insulating block 105 and the positioning frame 3, then rotate the abutment screw 311. The abutment screw 311 rotates and moves through its engagement with the adjusting screw hole 310, thus abutting... When the screw 311 disengages from the knob 102, the limiting collar 302 can be pulled out from the knob 102. Then, push the positioning frame 3 to push it out from the insulating block 105, thus separating the mounting box 2. The splicing operation can be achieved by reversing the above steps. The mounting frame 201 is glued to the mounting box 2. After the mounting box 2 is disassembled, it can be pulled out of the mounting box 2 by heating it with a hot air gun or exhaust fan. This will pull out the circuit board 202, battery 203 and indicator light 204 from the mounting box 2, so that damaged components can be replaced or repaired.

[0069] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
