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 frequently used safety tool 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, 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 in the event of a sudden power outage, and the current can be introduced into the ground, thereby protecting the lives of workers on the equipment.

[0003] At present, the locking of most ground wire products is generally achieved by padlocks. Padlocks are independent products and generally have their own identity information. The padlocks and ground wire head products are used at the same time, which is not convenient for managing the ground wire heads and padlocks, and the operation is also cumbersome. There is also a ground wire device that places the locking mechanism in the ground wire pile, and the ground wire head cooperates with the ground wire pile to adjust the structure. However, there are usually a large number of ground wire piles on site, and a small number of ground wire heads. Using this method to unlock the ground wire head will increase the temporary grounding cost, and the ground wire pile products are exposed to the outdoors for a long time, which will accelerate their aging and reduce their service life. The outdoor maintenance and replacement of the ground wire piles are also cumbersome. Summary of the invention

[0004] The embodiment of the present invention provides a ground wire head assembly, which can facilitate the management and protection of the detection device and facilitate the unlocking operation of the ground wire head.

[0005] The 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 a seat body, a seat body screw and a limiter. The seat body screw is located at one end of the seat body, the seat body screw can be inserted into the connection hole of the ground wire pile, and the limiter is movably connected with the seat body screw. The ground wire head includes an unlocked state and a locked state. In the unlocked state, the limiter is hidden in the seat body screw, so that the seat body screw can reciprocate in the connection hole of the ground wire pile; in the locked state, the limiter protrudes from the outer periphery of the seat body screw, so that the seat body screw is limited to the connection hole of the ground wire pile. The seat body screw has a channel, and the limiter includes a limiter rod, which is rotatably arranged in the channel. The detection device is arranged on the seat body, and the detection device includes a rotating drive member, and the rotating drive member includes a rotating output shaft, which is connected to the limiter rod, and the rotation of the rotating output shaft can drive the limiter rod to rotate, so that the ground wire head switches between the unlocked state and the locked state.

[0006] The technical solution of the present invention can avoid the cumbersome operation of locking with a padlock by setting the unlocking detection device on the ground wire head, and the ground wire head is generally placed in an indoor tool management cabinet, so that the ground wire head and the unlocking detection device can be better protected. The ground wire pile used in conjunction with the ground wire head can be a pure mechanical ground wire pile, which makes the ground wire pile less susceptible to damage, effectively reducing the management cost of the ground wire head and the ground wire pile, making it more convenient for users to use. A rotating drive member is set in the detection device, and the rotating drive member can drive the limit rod to rotate, so that the unlocking operation efficiency of the ground wire head is higher, and the user experience is improved.

[0007] According to the aforementioned embodiment of the present invention, the detection device further comprises: a sleeve having a receiving cavity, and the rotating driving member is installed in the receiving cavity. The receiving cavity can be beneficial to protecting the rotating driving member and prolonging the service life of the rotating driving member.

[0008] According to the aforementioned embodiment of the present invention, the detection device further includes: a mechanical lock core and a lock core transmission shaft. The lock core transmission shaft is connected between the mechanical lock core and the sleeve, and the mechanical lock core can drive the sleeve to rotate through the lock core transmission shaft, so that the rotating drive member rotates. By arranging the mechanical lock core and the lock core transmission shaft on the detection device, when an electrical failure occurs in the rotating drive member and the rotating output shaft cannot rotate, a manual emergency unlocking operation can be achieved mechanically to avoid delayed operation.

[0009] According to the aforementioned embodiment of the present invention, the end face of the sleeve facing away from the seat body screw is closed and provided with a first bevel gear, the rotation axis of the lock core transmission shaft is perpendicular to the axis of the sleeve, and the lock core transmission shaft has a second bevel gear meshing with the first bevel gear.

[0010] According to the aforementioned embodiment of the present invention, the mechanical lock core has an operating surface for receiving control operations, and the detection device further includes: a housing, the rotation drive member is located in the housing, and the operating surface of the mechanical lock core is exposed to the outer surface of the housing; a dust cover is movably connected to the housing, and the dust cover can cover the operating surface. By providing a dust cover above the mechanical lock core, fine dust can be prevented from falling into the mechanical lock core, avoiding the occurrence of mechanical lock core blocking, and extending the service life of the mechanical lock core.

[0011] According to the aforementioned embodiment of the present invention, the detection device also includes: a locked-in-place detection device, which is used to generate a locked-in-place signal when the rotating output shaft rotates to the ground wire head and is locked in place; and an unlocked-in-place detection device, which is used to generate an unlocked-in-place signal when the rotating output shaft rotates to the ground wire head and is unlocked in place.

[0012] According to the aforementioned embodiment of the present invention, the detection device further includes: a circuit board, the circuit board is electrically connected to the rotating drive member, the locking detection device and the unlocking detection device, and the circuit board includes a code reading module, and the code reading module is used to read the information of the ground wire pile. The detection device 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.

[0013] According to the aforementioned embodiment of the present invention, the seat body screw has at least one limiting hole, and the limiting hole connects the channel with the outer periphery of the seat body screw. The limiting member includes: at least one movable limiting body and a limiting rod. The movable limiting body is movably arranged in the limiting hole. The limiting rod includes at least one recessed portion, and the recessed portion can accommodate at least part of the movable limiting body. The limiting rod is connected to the rotating output shaft, and the limiting rod rotates so that the ground wire head switches between an unlocked state and a locked state. In the unlocked state, at least part of the movable limiting body is accommodated in the recessed portion, so that the limiting member is received within the outer peripheral surface of the seat body screw; in the locked state, the movable limiting body avoids the recessed portion and abuts against the outer peripheral surface of the limiting rod, so that the limiting member protrudes from the outer periphery of the seat body screw.

[0014] According to the aforementioned embodiment of the present invention, one end of the limit rod facing the rotary drive member extends out of the seat body screw and has a flat connection portion, which is connected to the rotary output shaft. The flat connection portion enables the rotary output shaft to better drive the limit rod to move, thereby improving efficiency and reducing manufacturing costs.

[0015] According to the aforementioned embodiment of the present invention, the movable stopper is a sphere, and the concave portion has a curved surface that matches at least a portion of the surface of the movable stopper. The curved surface of the concave portion reduces the resistance of the movable stopper during movement, making it easier for the movable stopper to protrude from the seat body screw or to be hidden inside the seat body screw.
