Description

Technical Field

[0001] The invention relates to the field of electrical equipment, and in particular to a ground wire head assembly. Background Art

[0002] The grounding wire is a safety tool frequently used in electrical work. When the power lines of electrical equipment are shut down for maintenance and inspection, in order to prevent sudden power outages, induced electricity and residual charges, and to ensure the safety of the lives of workers on the equipment, grounding wires must be installed in accordance with regulations on all sides of possible power outages and on electrical equipment that may generate induced electricity and store charges, to ensure that they can be safely short-circuited when sudden power outages occur, and to lead the current into the earth. In order to prevent major safety accidents in the power system and grid, and to prevent the occurrence of malicious misoperation accidents such as closing the live grounding wire, the power system currently mainly uses systems to strengthen the management of grounding wires and operators who use them, so as to reduce the probability of accidents. However, due to the carelessness of operators, accidents cannot be fundamentally avoided.

[0003] In places where products need to be temporarily grounded, such as substations, the locking of most grounding products is generally achieved by padlocks. Padlocks are independent products that generally have their own identity information. They are not easy to manage when used together with grounding head products. The padlock and grounding head must be used together, which is cumbersome and inefficient. There is also a grounding device that places the locking mechanism in the grounding pile, and the grounding head cooperates with the grounding pile for structural adjustment. However, there are usually more grounding piles and fewer grounding heads on site. This method will increase the cost of temporary grounding. The grounding pile product is exposed to the outdoors for a long time, which will accelerate its aging and reduce its service life. Outdoor maintenance and replacement are also cumbersome. In some cases, when the grounding wire is switched, an abnormal condition will cause the drive motor to stall, damage the drive motor, and reduce the service life of the motor. Summary of the invention

[0004] The embodiment of the present invention provides a ground wire head assembly, which can avoid the stalling of a driving component caused by an abnormal condition, reduce the damage to the driving component caused by the stalling, and extend the service life of the driving component.

[0005] An embodiment of the present invention provides a ground wire head assembly, which is used for detachably connecting with a ground wire pile. The ground wire head assembly includes: a ground wire head and a detection device. The ground wire head includes an unlocked state and a locked state. In the unlocked state, the ground wire head can be separated from the ground wire pile, and in the locked state, the ground wire head can be limited to the ground wire pile. The detection device is arranged on the ground wire head, and the detection device includes a driving member and a transmission assembly. The driving member can drive the partial structure of the ground wire head to move through the transmission assembly, so that the ground wire head can switch between the unlocked state and the locked state. Among them, the transmission assembly includes a first component and a second component, the first component is connected to the partial structure of the ground wire head, the second component is connected to the driving member, the first component and the second component are movably connected, and the second component can move to a preset position relative to the first component and then drive the first component to move synchronously.

[0006] The technical solution of the present invention can avoid the drive member from being blocked due to abnormal conditions, reduce damage to the drive member, and extend the service life of the drive member.

The lock core connector includes a second protrusion disposed between the first abutting portion and the second abutting portion, and the mechanical lock core can drive the second protrusion to abut against the first abutting portion and / or the second abutting portion, and drive the first component to slide along the guide groove.

[0013] According to the aforementioned embodiment of the present invention, the detection device also includes: a locked-in-place detection device, which is arranged on the transmission base, and the locked-in-place detection device is used to generate a locked-in-place signal when the ground wire head is locked in place; and an unlocked-in-place detection device, which is arranged on the transmission base, and the unlocked-in-place detection device is used to generate an unlocked-in-place signal when the ground wire head is unlocked in place.

[0014] According to the aforementioned embodiment of the present invention, the detection device further comprises: a circuit board, a code reading module is arranged on the circuit board, a code chip is arranged on the ground wire pile, the code reading module can identify the code chip, and the circuit board is electrically connected to the driving member.

The detection device 120 is arranged on the ground wire head 110.

[0041] Figure 2 The exploded schematic diagram of an embodiment of the ground wire head assembly of the present invention, the detection device 120 includes a driving member 121 and a transmission assembly 122. The driving member 121 can drive a part of the structure of the ground wire head 110 to move through the transmission assembly 122, so that the ground wire head 110 can switch between an unlocked state and a locked state.

[0042] Figure 3 This is an exploded schematic diagram of the transmission component of an embodiment of the ground wire head component of the present invention. The transmission component 122 includes a first component 1221 and a second component 1222. The first component 1221 is connected to a partial structure of the ground wire head 110, and the second component 1222 is connected to the driving member 121. The first component 1221 and the second component 1222 are movably connected. The second component 1222 can move to a preset position relative to the first component 1221 and drive the first component 1221 to move synchronously.

[0043] The technical solution of the present invention can avoid the drive member 121 from being blocked due to abnormal conditions, reduce damage to the drive member 121, and extend the service life of the drive member 121. By setting the unlocking detection device 120 on the ground wire head 110, the cumbersome operation of locking with a padlock can be avoided, and the ground wire head 110 is generally placed in an indoor tool management cabinet, so that the ground wire head 110 and the unlocking detection device 120 can be better protected, and the ground wire pile 200 used in conjunction with the ground wire head 110 can be a pure mechanical ground wire pile 200, so that the ground wire pile 200 is not easily damaged, effectively reducing the management cost of the ground wire head 110 and the ground wire pile 200, making it more convenient for users to use.

[0044] In this embodiment, the grounding head 110 and the detection device 120 are integrated. In other embodiments, other installation methods may be used, such as the grounding head 110 and the detection device 120 are separately assembled. This application does not limit the installation method, and those skilled in the art can choose the connection installation method according to actual needs.

[0045] like Figures 3 to 5 As shown, the preset position includes a first preset position and a second preset position. After the second component 1222 moves relative to the first component 1221 to the first preset position, it drives the first component 1221 to move synchronously, so that the ground wire head 110 switches from an unlocked state to a locked state; after the second component 1222 moves relative to the first component 1221 to the second preset position, it drives the first component 1221 to move synchronously, so that the ground wire head 110 switches from a locked state to an unlocked state.

The first preset position of the second component 1222 relative to the first component 1221 is the position when the first spring S1 is compressed to a position that cannot be compressed any further, and the second preset position of the second component 1222 relative to the first component 1221 is the position when the second spring S2 is compressed to a position that cannot be compressed any further. The first component 1221 and the second component 1222 are elastically connected by the elastic member ST, so that when an abnormal situation occurs, the driving member 121 can still drive the transmission assembly 122 to move, thereby reducing damage to the driving member 121 and extending the service life of the driving member 121.

[0047] like Figure 3 As shown, the second component 1222 has a second slide groove P2, and the extension direction of the second slide groove P2 intersects with the extension direction of the first slide groove P1. The driving member 121 is a driving motor, and the driving motor includes a rotating output shaft 1211. The transmission assembly 122 also includes: a rotating shaft connecting member 1225, the rotating shaft connecting member 1225 is connected to the rotating output shaft 1211, and the rotating shaft connecting member 1225 has an eccentrically arranged first protrusion P4, and the first protrusion P4 extends into the second slide groove P2. The rotation of the rotating output shaft 1211 can drive the second component 1222 to reciprocate.

[0048] like Figure 3 As shown, the transmission assembly 122 further includes a transmission base 1224, the transmission base 1224 has a guide groove P3, the first component 1221 is slidably disposed in the guide groove P3, and the extension direction of the first slide groove P1 is parallel to the extension direction of the guide groove P3.

[0049] like Figure 2 As shown, in some embodiments, the detection device 120 further includes: a mechanical lock core 127, which is connected to the transmission base 1224; and a lock core connector 128, which is connected to the mechanical lock core 127, and the mechanical lock core 127 can drive the first component 1221 to reciprocate through the lock core connector 128. A dust cover 1271 is provided above the mechanical lock core 127 to prevent fine dust from falling into the mechanical lock core 127, causing the mechanical lock core 127 to be blocked and reducing the service life of the mechanical lock core 127.

[0050] like Figure 3 As shown, the first component 1221 has a first abutting portion W3 and a second abutting portion W4, and the first abutting portion W3 and the second abutting portion W4 are arranged at intervals in the extension direction of the first slide groove P1. The lock core connecting member 128 includes a second protruding portion P6 disposed between the first abutting portion W3 and the second abutting portion W4, and the mechanical lock core 127 can drive the second protruding portion P6 to abut against the first abutting portion W3 and / or the second abutting portion W4, and drive the first component 1221 to slide along the guide groove P3.

[0051] like Figure 2 As shown, the detection device 120 also includes: a locked in place detection device 123 and an unlocked in place detection device 124.

[0052] like Figure 1 to Figure 2 As shown, the detection device 120 also includes: a circuit board 125, a code reading module is arranged on the circuit board 125, a code chip 210 is arranged on the ground wire pile 200, the code reading module can identify the code chip 210, and the circuit board 125 is electrically connected to the driving member 121. The code reading module includes a first code reading module 1251 and a second code reading module 1252. When the ground wire head 110 is close to the ground wire pile 200, the code chip 210 on the ground wire pile 200 identifies the first code reading module 1251 on the ground wire head 110, and the ground wire head 110 performs a locking operation; when the ground wire head 110 is far away from the ground wire pile 200, the code chip 210 on the ground wire pile 200 identifies the second code reading module 1252 on the ground wire head 110, and the ground wire head 110 performs an unlocking operation. The detection device 120 has an electronic control part and a logic judgment function, which effectively improves the intelligence of the ground wire hanging and avoids the safety hazards caused by abnormal operations in the hanging of ordinary ground wire devices in the past.

[0053] Figure 6The exploded schematic diagram of the ground wire head of one embodiment of the ground wire head assembly of the present invention. The ground wire head 110 includes: a seat body 111, a seat body screw 112 and a limiter 113. The seat body screw 112 is located at one end of the seat body 111, and the seat body screw 112 can be inserted into the connection hole 220 of the ground wire pile 200. The limiter 113 is movably connected to the seat body screw 112. In the unlocked state, the limiter 113 is hidden in the seat body screw 112, so that the seat body screw 112 can reciprocate in the connection hole 220 of the ground wire pile 200; in the locked state, the limiter 113 protrudes from the outer periphery of the seat body screw 112, so that the seat body screw 112 is limited to the connection hole 220 of the ground wire pile 200.

[0054] like Figure 5 As shown, the seat screw 112 includes a channel located inside and at least one seat screw hole 1122, and the seat screw hole 1122 connects the channel 1121 with the periphery of the seat screw 112. The limiting member 113 includes: at least one movable limiting body 1131 and a limiting rod 1132. The movable limiting body 1131 is movably disposed in the seat screw hole 1122. The limiting rod 1132 is movably disposed in the channel 1121, and the limiting rod 1132 includes at least one recessed portion P5, and the recessed portion P5 can accommodate at least part of the movable limiting body 1131. In the unlocked state, at least part of the movable stopper 1131 is accommodated in the recessed portion P5, so that the stopper 113 is received within the outer circumference of the seat screw 112; in the locked state, the movable stopper 1131 avoids the recessed portion P5 and abuts against the outer circumference of the stopper rod 1132, so that the stopper 113 protrudes from the outer circumference of the seat screw 112. The grounding head 110 can be switched to the unlocked state by the repeated axial movement of the stopper rod 1132.

[0055] In this embodiment, the seat screw 112 includes two seat screw holes 1122, and the ground wire head 110 includes two limiters 113. In other embodiments, other numbers of limiters 113 that are conducive to the unlocking operation of the ground wire pile 200 may also be used, such as four, six, etc. The present application does not limit the number of limiters 113, and those skilled in the art can select the number of limiters 113 according to actual needs.

[0056] like Figure 5 As shown, the movable stopper 1131 is a sphere, and the recessed portion P5 has a curved surface that matches at least a portion of the surface of the movable stopper 1131. The curved surface of the recessed portion P5 reduces the resistance of the movable stopper 1131 during movement, making it easier for the movable stopper 1131 to protrude from the seat screw 112 or to be hidden inside the seat screw 112.

[0057] like Figure 6As shown, the limiting member 113 further includes a limiting sleeve 1133, which is disposed in the seat body screw hole 1122 and is used to limit the movable limiting body 1131 in the seat body screw hole 1122. The limiting sleeve 1133 prevents the movable limiting body 1131 from falling out of the seat body screw hole 1122.

[0058] In this embodiment, the movable limiting body 1131 is a first steel ball and a second steel ball arranged opposite to each other, and the heads of the first steel ball and the second steel ball are respectively provided with limiting sleeves 1133. In other embodiments, other shapes of the limiting member 113 and materials of the limiting member 113 that are conducive to the unlocking operation of the ground wire pile 200 can also be adopted. The present application does not limit the shape and material of the limiting member 113, and those skilled in the art can select the shape and material of the limiting member 113 according to actual needs.

[0059] The limiting rod 1132 is configured to be able to reciprocate along the axial direction of the seat body screw 112. The axial reciprocating motion of the limiting rod 1132 enables the ground wire head 110 to switch between an unlocked state and a locked state.

[0060] In this embodiment, the transmission assembly 122 is a reciprocating transmission assembly 122 , and the reciprocating rotation assembly is used to drive the limiting rod 1132 under the drive of the driving member 121 , so that the limiting rod 1132 can reciprocate along the axial direction of the seat body screw 112 .

[0061] In this embodiment, the limiting rod 1132 performs axial reciprocating motion along the seat screw 112. In other embodiments, other motion modes that are beneficial to the limiting rod 1132 relative to the seat screw 112 may also be adopted, such as rotational motion, etc. The present application does not limit the motion mode of the limiting rod 1132 relative to the seat screw 112, and those skilled in the art may select the motion mode of the limiting rod 1132 relative to the seat screw 112 according to actual needs.

[0062] like Figure 6 The ground wire head 110 further includes: a clamping nut 114 and a bolt 115.
