Description

Technical Field

[0001] This invention relates to the field of power grounding device technology, specifically to a mechanical interlocking device for preventing misoperation of substation grounding wires. Background Technology

[0002] According to the "State Grid Corporation of China Power Safety Work Regulations," when installing grounding wires, the grounding end should be installed first, followed by the conductor. However, grounding wire operators often violate these regulations by failing to install and remove the conductor and grounding ends in the correct order, leading to personal injury and equipment damage.

[0003] To prevent this misoperation, the common practice is to conduct annual training on the "State Grid Corporation of China Power Safety Work Regulations" to improve personnel quality, but there is no effective and simple reliable device. To enforce compliance with the requirements of the "State Grid Corporation of China Power Safety Work Regulations" by grounding wire operators, a more direct method is to use an electronic logic interlocking device composed of sensors, motors, insulating barriers, batteries, and other components. The insulating barrier blocks the conductor end; when the grounding sensor detects that the grounding end is correctly installed, it sends a signal to the motor controller, controlling the motor to open the insulating barrier.

[0004] However, this solution is costly and inconvenient to maintain. It involves the use of precision components such as motors and sensors, which are expensive to purchase, highly susceptible to environmental pollution and corrosion, and require batteries, resulting in frequent and inconvenient maintenance. It is also unsuitable for use in high-voltage, strong magnetic field environments. High-voltage grounding wires are typically used in substations, and the grounding wire ends need to be clamped to the conductor. In the high-voltage, strong magnetic field environment of a substation, the copper coils inside the sensors and small motors are prone to generating high currents through electromagnetic induction, damaging components and even the grounding wire and electrical equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a mechanical interlocking device to prevent misoperation of substation grounding wires, in order to solve the problem in the prior art where grounding wire operators often fail to install or remove the conductor end and grounding end in the correct order when installing or removing grounding wires, resulting in personal injury or equipment damage.

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

[0009] The grounding terminal is provided with a grounding connecting rod for connecting to the grounding locking terminal and a grounding connecting port for connecting to the grounding wire.

[0010] In a preferred embodiment of the present invention, during the process of connecting the grounding wire to the grounding connection port, the grounding wire contacts the grounding locking end and drives the grounding locking end to move. The grounding locking end drives the equipment locking end to move through the connecting pipe, so that the cover plate assembly moves to expose the equipment connection port, making it easier for the grounding wire to connect to the equipment connection port.

[0011] In a preferred embodiment of the present invention, the cover plate assembly includes a cover sliding cavity disposed on the side wall of the device connection port, and a cover sliding plate is slidably disposed in the cover sliding cavity.

[0012] In a preferred embodiment of the present invention, the covering sliding cavity is connected to the device surface through a covering drive port, the upper surface of the covering slide plate is provided with a covering tooth groove, and there are two device connecting rods, which are respectively disposed on both sides of the covering drive port.

[0013] As a preferred embodiment of the present invention, the device locking end includes a first fixed seat, the bottom surface of the first fixed seat is provided with a first driving cavity and two first fixing holes, the two first fixing holes respectively correspond to the two device connecting rods, and when the two device connecting rods are inserted into the two first fixing holes respectively, the first driving cavity is opposite to the cover driving port.

[0014] As a preferred embodiment of the present invention, a first rotating gear is provided at the top of the first driving cavity, a second rotating gear is provided at the bottom of the first driving cavity, a first synchronous belt is wound between the first rotating gear and the second rotating gear, and the second rotating gear meshes with the cover tooth groove through the cover driving port.

[0015] As a preferred embodiment of the present invention, there are several grounding connecting rods, and the grounding locking end includes a second fixing seat. The bottom surface of the second fixing seat is provided with several second fixing holes, and the several second fixing holes correspond to several of the grounding connecting rods respectively.

[0016] In a preferred embodiment of the present invention, the second fixed base is provided with a vertical lifting sliding cavity, and a lifting sliding seat is vertically slidably disposed in the lifting sliding cavity. A lifting drive rod is connected to the right side of the lifting sliding seat, and the lifting drive rod extends out of the right side of the second fixed base.

[0017] In a preferred embodiment of the present invention, the second fixed seat is provided with a second driving cavity, and a third rotating gear and a fourth rotating gear are provided in the second driving cavity. A second synchronous belt is wound between the third rotating gear and the fourth rotating gear. The second driving cavity is connected to the lifting sliding cavity.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention, by setting up an equipment locking end, a grounding locking end, a connecting pipe, and a cover plate assembly, ensures that when connecting the grounding wire, the cover plate assembly closes the equipment connection port, leaving only the grounding connection port exposed.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 8 As shown, the present invention provides a mechanical interlocking device for preventing misoperation of a substation grounding wire, including an equipment interlocking end 1, a grounding interlocking end 2, and a connecting pipe 3 connecting the two. The equipment interlocking end 1 and the grounding interlocking end 2 are respectively used to connect the equipment 4 and the grounding end 5. The equipment 4 is provided with an equipment connecting rod 401 for connecting to the equipment interlocking end 1, an equipment connection port 402 for connecting to the grounding wire, and a cover plate assembly 6 for sealing the equipment connection port 402. The grounding end 5 is provided with a grounding connecting rod 501 for connecting to the grounding interlocking end 2 and a grounding connection port 502 for connecting to the grounding wire.

[0040] It should be noted that before connecting the grounding wire in this embodiment, the equipment connection port 402 is in a closed state and the grounding connection port 502 is in an exposed state. In this state, the operator can only connect the grounding wire to the grounding terminal 5 first, and then connect it to the equipment 4. This forces the operator to operate in the order of grounding first and then connecting the equipment, effectively preventing the grounding wire operator from misoperating and ensuring personal and equipment safety.

[0041] During the process of connecting the grounding wire to the grounding connection port 502, the side of the grounding wire or the side of the fingers holding the grounding wire comes into contact with the grounding locking end 2 and drives the grounding locking end 2 to move. The grounding locking end 2 drives the equipment locking end 1 to move through the connecting pipe 3, so that the cover plate assembly 6 moves to expose the equipment connection port 402, making it easier for the grounding wire to be connected to the equipment connection port 402.

[0042] It is worth noting that the equipment connection port 402 is closed by the cover plate assembly 6. The cover plate assembly 6 is driven sequentially by the cover plate assembly 6, the connecting pipe 3 and the grounding locking end 2, and is combined with the operation of the grounding wire being installed at the grounding end 5. The equipment connection port 402 is opened during the process of connecting the grounding wire to the grounding end 5, rather than by a separate drive structure. This avoids the operator from forcibly opening the equipment connection port 402 first, thus preventing misoperation and ensuring the safety of personnel and equipment.

[0043] Based on this, in this embodiment, the cover plate assembly 6 includes a cover sliding cavity 601 disposed on the side wall of the device connection port 402. A cover sliding plate 602 is slidably disposed in the cover sliding cavity 601. When the cover sliding plate 602 moves out of the cover sliding cavity 601, the cover sliding plate 602 closes the device connection port 402. The cover sliding cavity 601 is connected to the surface of the device 4 through a cover driving port 603. A cover tooth groove 604 is provided on the upper surface of the cover sliding plate 602. There are two device connecting rods 401, which are respectively disposed on both sides of the cover driving port 603.

[0044] Furthermore, the device locking end 1 includes a first fixed base 101. The bottom surface of the first fixed base 101 is provided with a first driving cavity 102 and two first fixing holes 103. The two first fixing holes 103 correspond to two device connecting rods 401 respectively. When the two device connecting rods 401 are inserted into the two first fixing holes 103 respectively, the first driving cavity 102 is opposite to the cover driving port 603. A first rotating gear 104 is provided at the top of the first driving cavity 102, and a second rotating gear 105 is provided at the bottom of the first driving cavity 102. A first synchronous belt 106 is wound between the first rotating gear 104 and the second rotating gear 105. The second rotating gear 105 meshes with the cover tooth groove 604 through the cover driving port 603.

[0045] When the first rotating gear 104 rotates, it drives the second rotating gear 105 to rotate via the first synchronous belt 106. The second rotating gear 105 drives the covering tooth groove 604 to translate, which means that the covering slide plate 602 slides. When the covering slide plate 602 slides out of the covering sliding cavity 601, it enters the equipment connection port 402, thereby preventing the grounding wire from entering the equipment connection port 402, which means that the equipment connection port 402 is closed. When the covering slide plate 602 slides deeper into the covering sliding cavity 601, the covering slide plate 602 disengages from the equipment connection port 402. When the covering slide plate 602 is completely retracted in the covering sliding cavity 601, the equipment connection port 402 is completely exposed, and the grounding wire can smoothly enter the equipment connection port 402 to realize the connection between the grounding wire and the equipment 4.

[0046] In this embodiment, there are several grounding connecting rods 501, and the grounding locking end 2 includes a second fixing seat 201. The bottom surface of the second fixing seat 201 is provided with several second fixing holes 202, which correspond to several grounding connecting rods 501 respectively. The second fixing seat 201 is provided with a vertical lifting sliding cavity 203. A lifting sliding seat 204 is vertically slidably arranged in the lifting sliding cavity 203. A lifting drive rod 205 is connected to the right side of the lifting sliding seat 204. The lifting drive rod 205 extends out of the right side of the second fixing seat 201. The side wall of the second fixing seat 201 is provided with a sliding gap for the lifting drive rod 205 to move up and down.

[0047] Furthermore, the second fixed base 201 is provided with a second driving cavity 206, and a third rotating gear 207 and a fourth rotating gear 208 are provided in the second driving cavity 206. A second synchronous belt 209 is wound between the third rotating gear 207 and the fourth rotating gear 208. The second driving cavity 206 is connected to the lifting sliding cavity 203. The surface of the lifting sliding base 204 is provided with a lifting tooth groove 210. The fourth rotating gear 208 is a one-way gear and meshes with the lifting tooth groove 210.

[0048] It should be noted that when the grounding connection rod 501 is inserted into the corresponding second fixing hole 202, the lifting drive rod 205 is close to the grounding connection port 502. When the grounding wire is connected to the grounding connection port 502, the side of the grounding wire will contact the lifting drive rod 205. When the grounding wire moves down, it will drive the lifting drive rod 205 to move down. Alternatively, when the operator pinches the grounding wire and inserts it into the grounding connection port 502, the operator's fingers will contact the lifting drive rod 205. When the grounding wire moves down, it will drive the lifting drive rod 205 to move down, thereby causing the lifting sliding seat 204 to slide vertically downward in the lifting sliding cavity 203, which in turn causes the lifting tooth groove 210 to move down. The downward movement of the lifting tooth groove 210 drives the fourth rotating gear 208 to rotate, and the fourth rotating gear 208 drives the third rotating gear 207 to rotate through the second synchronous belt 209.

[0049] It should be further explained that the connecting pipe 3 includes a pipe housing 301, and two internal channels 302 are provided inside the pipe housing 301. A synchronization strip 303 is provided inside the internal channels 302. The two ends of the synchronization strip 303 extend into the first driving cavity 102 and the second driving cavity 206, respectively, and are connected to the first rotating gear 104 and the third rotating gear 207, respectively.

[0050] Thus, when the lifting drive rod 205 moves down, the third rotating gear 207 rotates, and the third rotating gear 207 drives the first rotating gear 104 to rotate through the synchronous belt 303, thereby causing the cover plate 602 to move, thereby realizing the control of the exposed / closed state of the equipment connection port 402.

[0051] It is worth noting that the diameter of the internal channel 302 is greater than the width of the synchronous strip 303, allowing the synchronous strip 303 to slide in the internal channel 302. Even when the connecting pipe 3 is bent, the synchronous strip 303 can still slide, thereby allowing the first rotating gear 104 and the third rotating gear 207 to rotate, thus realizing the linkage between the equipment locking end 1 and the grounding locking end 2.

[0052] This embodiment, by setting up an equipment locking end 1, a grounding locking end 2, a connecting pipe 3, and a cover plate assembly 6, ensures that when connecting the grounding wire, the cover plate assembly 6 closes the equipment connection port 402, leaving only the grounding connection port 502 exposed. After the equipment locking end 1 and the grounding locking end 2 are respectively connected to the equipment 4 and the grounding end 5, the process of connecting the grounding wire to the grounding connection port 502 is achieved by the grounding locking end 2, the connecting pipe 3, and the equipment locking end 1 driving the cover plate assembly 6 to expose the equipment connection port 402. This allows for the sequential connection of the grounding connection port 502 and the equipment connection port 402, forcing the grounding operation to follow the order of grounding first and then connecting the equipment, effectively preventing grounding wire operators from making mistakes and ensuring personal and equipment safety.

[0053] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
