Description

Technical Field

[0001] The present invention relates to the technical field of grounding equipment, and in particular to a reserved grounding connection structure and a grounding detection method. Background Art

[0002] In order to ensure that when the equipment is being repaired, someone suddenly sends electricity by mistake and the static electricity generated by the equipment itself will not cause harm to the maintenance personnel, so the ground wire must be hung during the maintenance of electrical equipment. The ground wire is a safety barrier to protect the maintenance personnel and is the lifeline of power employees. At the grounding end, the traditional practice is to drive a grounding stake or use a grounding wire clamp to connect the wire clamp to the flat iron by rotating the grounding wire rod, which is laborious and difficult to operate. At the same time, the rotating wire clamp often falls off the flat iron when rotating and tightening. At the conductor end, there are also two traditional connection methods, one is to use the grounding wire clamp to connect the wire clamp to the conductor by rotating the grounding wire rod, and the other is to use a double-tongue hook grounding rod. The use of a rotating wire clamp has the problem of unreliable contact between the grounding wire clamp and the conductor due to operational reasons; the use of a double-tongue hook grounding rod has the problem of virtual hanging.

[0003] In addition, after improving the existing grounding device and solving the problem of virtual hanging, the reliability of the grounding device is also an important factor affecting the safety of maintenance personnel. That is to say, whether the grounding device itself is stable when grounded, and whether it can maintain a stable connection during long-term operation is also a defect in the existing technology. Summary of the invention

[0004] In view of the above existing technical problems, the present invention is proposed.

[0005] The present invention aims to provide a reserved grounding connection structure, which aims to solve the problem that the grounding wire clamp and the conductor are not in firm contact.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a reserved grounding connection structure, which includes a stabilizing component, including a fixing member, a receiving member arranged outside the fixing member, and a supporting member arranged inside the receiving member, and the supporting member is movably connected to the receiving member; wherein the fixing member is movably matched with the receiving member, and the supporting member is movably matched with the fixing member.

[0007] As a preferred solution of the reserved grounding connection structure of the present invention, the fixing member includes a reserved end and an installation end, and one end of the reserved end is fixedly connected to the inside of the wire or the grounding body.

[0010] As a preferred solution of the reserved grounding connection structure of the present invention, the support member includes an elastic element which is arranged inside the wiring terminal and movably connected to the wiring terminal.

[0011] As a preferred solution of the reserved grounding connection structure of the present invention, the mounting end includes a mounting rod and a mounting block, the mounting rod is fixedly connected to the other end of the reserved end, and the mounting block is arranged on the outer wall of the mounting rod.

[0012] As a preferred solution of the reserved grounding connection structure of the present invention, wherein: the end face of the wiring terminal is penetrated by a first slide groove cooperating with the mounting rod, the interior of the wiring terminal is also provided with a receiving groove connected with the first slide groove and connected with the first slide groove, the end face of the wiring terminal is also provided with a second slide groove connected with the first slide groove and movably cooperated with the mounting block, and the second slide groove is connected with the receiving groove.

[0013] As a preferred solution of the reserved grounding connection structure of the present invention, wherein: a connecting piece is movably arranged inside the wiring terminal, and the connecting piece includes a moving contact movably arranged inside the wiring terminal and a static contact cooperating with the moving contact and fixedly connected to the wiring terminal, and a third sliding groove is also provided on the end surface of the wiring terminal, and a trigger rod is slidably arranged in the third sliding groove, the trigger rod is fixedly connected to the moving contact, and the trigger rod is fixedly connected to the reserved end.

[0014] The beneficial effect of the reserved grounding connection structure of the present invention is: by sliding the set fixing piece into the interior of the accommodating piece, the fixing piece is stably fixed in the accommodating piece through the elastic action of the supporting piece, thereby achieving contact between the static contact and the moving contact, and preventing the grounding device from hanging in vain during use.

[0015] Another object of the present invention is to provide a grounding detection method, which aims to solve the reliability problem of the grounding device.

[0016] In order to solve the above technical problems, the present invention also provides the following technical solutions: a grounding detection method, which includes a reserved grounding connection structure; when the connector is closed or disconnected, a timer is added before the connector to determine whether the connector is in a closed or disconnected state at a set time, and finally controls the connection or disconnection of the ground at this time according to the set time.

[0017] As a preferred solution of the grounding detection method of the present invention, wherein: if the connector is in a closed state at this time, the disconnection counter is reset to zero to determine the connection state at this time, and if the connection state at this time is connected, it means that the connection of the stabilizing component is stable at this time, and the grounding connection structure is grounded;

[0018] If the connection state is disconnected at this time, the connection counter is further used to accumulate the count according to the set parameters to determine whether the grounding device is always in a stable state each time the cumulative count is added. If so, the grounding structure is grounded, otherwise it is not grounded.

[0019] The beneficial effect of the grounding detection method of the present invention is: through the detection method of the timer counter, when the static contact contacts the moving contact, the grounding device is not immediately grounded or disconnected, but further and continuously detects the connection status at this time through a preset time. When the connection status is stable, the loop is completely grounded or disconnected, thereby increasing the stability of the grounding structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, reference Figure 1 , which is the first embodiment of the present invention, and provides a reserved ground connection structure, including a stabilizing component 100, including a fixing member 101, a receiving member 102 disposed outside the fixing member 101, and a supporting member 103 disposed inside the receiving member 102, wherein the supporting member 103 is movably connected to the receiving member 102;

[0030] The fixing member 101 is movably matched with the receiving member 102 , and the supporting member 103 is movably matched with the fixing member 101 .

[0031] Preferably, one end of the fixing member 101 is fixedly connected to the wire or the grounding body, and the other end is exposed to the outside world. The fixing member 101 has a conductive property, and the receiving member 102 is arranged outside the fixing member 101 and is a movable part. When a grounding connection is required, the receiving member 102 is connected to the fixing member 101 to achieve conduction of the circuit.

[0032] Furthermore, the support member 103 has elastic deformation and conductivity.

[0033] In summary, when a grounding connection is required, the staff lifts the receiving part 102 with an automatic device such as a lifting rod or a robotic arm, and connects the fixed part 101 exposed to the outside with the receiving part 102. When the exposed side of the fixed part 101 contacts the support part 103, the support part 103 undergoes elastic deformation, and finally when the receiving part 102 is released, the side of the fixed part 101 exposed to the outside contacts the support part 103, so that the circuit is turned on, thereby completing the grounding connection work.

[0034] Example 2, reference Figure 1-2 , which is the second embodiment of the present invention, and further provides a reserved grounding connection structure. The fixing member 101 includes a reserved end 101a and a mounting end 101b, and one end of the reserved end 101a is fixedly connected to the inside of the wire or the grounding body.

[0035] Preferably, a portion of the reserved end 101a is fixedly connected to a wire or a grounding body, and is used to connect the current in the wire or the grounding body;

[0036] Furthermore, the reserved end 101a is cylindrical as a whole in this embodiment, and a part of the reserved end 101a is exposed to the outside.

[0037] The other end of the mounting end 101 b is fixedly connected to the mounting end 101 b , and the mounting end 101 b is slidably connected to the receiving member 102 .

[0038] Preferably, the installation end 101b is similar to the reserved end 101a, and is presented in the form of a cylinder in this embodiment, and the installation end 101b is also conductive;

[0039] The receiving member 102 includes a wiring terminal 102a, and the wiring terminal 102a is movably matched with the mounting terminal 101b.

[0040] Preferably, the outer diameters of the connection terminal 102a and the reserved end 101a are almost equal.

[0041] The support member 103 is disposed inside the wiring terminal 102a, and the support member 103 includes an elastic element 103a movably connected to the wiring terminal 102a.

[0042] Furthermore, the elastic element 103a in this embodiment is a spring, and the elastic element 103a is slidably disposed inside the wiring terminal 102a.

[0043] A movable conductor 103b is disposed inside the elastic element 103a.

[0044] The mounting end 101b includes a mounting rod 101d and a mounting block 101e. The mounting rod 101d is fixedly connected to the other end of the reserved end 101a, and the mounting block 101e is arranged on the outer wall of the mounting rod 101d.

[0045] Preferably, the mounting block 101e is fixedly mounted on the outer wall of the mounting rod 101d, and two mounting blocks 101e are symmetrically arranged. The side of the mounting block 101e away from the wire or the grounding body is a plane with a certain area, which facilitates the contact between the mounting block 101e and the elastic element 103a.

[0046] A first slide groove 102b cooperating with the mounting rod 101d is formed through the end surface of the terminal 102a, and a receiving groove 102c connected to the first slide groove 102b is formed inside the terminal 102a. A second slide groove 102d connected to the first slide groove 102b and movably cooperating with the mounting block 101e is formed on the end surface of the terminal 102a, and the second slide groove 102d is connected to the receiving groove 102c.

[0047] Preferably, the first slide groove 102b is arranged throughout the entire terminal 102a;

[0048] Furthermore, the receiving groove 102c is connected to the first slide groove 102b, and the radius of the receiving groove 102c is greater than the radius of the first slide groove 102b. At the same time, the radius of the receiving groove 102c is greater than the radius of the inscribed circle of the mounting rod 101d and the two symmetrically arranged mounting blocks 101e, and the radius of the receiving groove 102c is smaller than the outer diameter of the terminal 102a.

[0049] A connector 104 is movably provided inside the terminal 102a, and the connector 104 includes a moving contact 104a movably provided inside the terminal 102a and a static contact 104b cooperating with the moving contact 104a and fixedly connected to the terminal 102a. A third slide groove 104c is also provided on the end surface of the terminal 102a, and a trigger rod 104d is slidably provided in the third slide groove 104c. The trigger rod 104d is fixedly connected to the moving contact 104a, and the trigger rod 104d is movably cooperated with the reserved end 101a.

[0050] Preferably, both the moving contact 104a and the static contact 104b have conductive properties, and the static contact 104b is externally connected with a wire, which is respectively connected to the ground terminal of the detection circuit and one end of the control chip.

[0051] Furthermore, the third slide groove 104c is arranged in parallel with the first slide groove 102b, and both the third slide groove 104c and the first slide groove 102b are opened from the end surface of the wiring terminal 102a close to the fixing member 101, but at different positions.

[0052] Furthermore, there is a certain space inside the terminal 102a for installing the static contact 104b, which is located within the outer circumference of the first sliding groove 102b and the terminal 102a.

[0053] Furthermore, a second spring is disposed inside the third slide slot 104c and fixedly connected to the trigger rod 104d. When no external force is applied, the trigger rod 104d moves away from the static contact 104b through the elastic force, so that the static contact 104b and the moving contact 104a are separated.

[0054] When the mounting rod 101d slides into the first slide groove 102b, as the mounting rod 101d gradually approaches the elastic element 103a, the end of the reserved end 101a away from the wire or the grounding body contacts the trigger rod 104d, causing the trigger rod 104d to move to the side away from the wire or the grounding body. When the upper surface of the mounting block 101e completely leaves the second slide groove 102d, the static contact 104b contacts the moving contact 104a, turning on the detection circuit.

[0055] In summary, when circuit maintenance is required, that is, when the grounding device needs to be connected, the staff lifts the terminal 102a with an automatic device such as a lifting rod or a robotic arm, aligns the second slide groove 102d with the mounting block 101e, and moves the terminal 102a closer to one end of the wire or the grounding body. When the upper surface of the mounting block 101e is completely out of the second slide groove 102d, the elastic element 103a is compressed, and the terminal 102a is rotated to make the mounting block 101e out of the alignment with the second slide groove 102d. At this time, the end of the reserved end 101a away from the wire or the grounding body contacts the trigger rod 104d, the static contact 104b contacts and conducts with the moving contact 104a, and the mounting rod 101d is connected with the movable conductor 103b, thereby turning on the detection circuit.

[0056] Example 3, reference Figure 3 , which is the third embodiment of the present invention, and this embodiment provides another implementation method of a reserved grounding connection structure.

[0057] like Figure 3 As shown, one end of the reserved end 101a is still fixedly set in the wire or the grounding body. At this time, a movable ring 101f is sleeved on the end of the reserved end 101a away from the wire or the grounding body. A third spring 101i is arranged between the movable ring 101f and the outer wall of the reserved end 101a. The third spring 101i enables the movable ring 101f and the reserved end 101a to be slidably and elastically connected.

[0058] The end of the reserved end 101a away from the wire is supported by multiple mounting blocks 101e. At this time, the mounting blocks 101e are spherical in this embodiment and are movably arranged in the holes opened by the movable collar 101f. Multiple mounting blocks 101e are arranged in an array along the circumference of the movable collar 101f. The inner wall of the end of the movable collar 101f away from the wire is provided with a slot 101j that can accommodate the mounting blocks 101e. The mounting rod 101d is movably connected to the reserved end 101a, and a sliding groove 101h is provided in the reserved end 101a, and between the sliding groove 101h and the mounting rod 101d.

[0059] In this embodiment, the total receiving member 101 is still movably matched with the fixing member 101, and the receiving groove 102c provided on the wiring terminal 102a outside the movable conductor 103b is located on the outer wall of the wiring terminal 102a;

[0060] When in use, the movable ring 101f is moved toward the side of the wire or the grounding body, so that the spherical mounting block 101e in this embodiment falls into the slot 101j, and then when the terminal 102a is moved, the movable conductor 103 contacts the mounting rod 101d to conduct the circuit. At this time, the movable ring 101f is released, and the mounting block 101e is snapped into the receiving slot 102c in this embodiment to prevent the grounding terminal 102a from falling off.

[0061] Example 4, reference Figure 4 , which is the fourth embodiment of the present invention, and this embodiment provides a ground detection circuit principle;

[0062] When the moving contact 104a contacts the stationary contact 104b, the initial condition for the circuit to be turned on is completed;

[0063] One end of the detection circuit is connected to an MSP430G2553 control chip, which is used to control the detection circuit outside the chip so that the entire circuit is turned on or off, that is, grounded or disconnected, after the moving contact 104a and the static contact 104b are in contact or disconnected for a period of time.

[0064] Example 5, reference Figure 5 , which is the fifth embodiment of the present invention, provides a grounding detection method, including adding a timer before the connector 104 when the connector 104 is closed or disconnected, judging whether the connector 104 is in a closed or disconnected state at a set time, and finally controlling the connection or disconnection of the ground at this time according to the set time.

[0065] If the connector 104 is in a closed state at this time, the disconnection counter is reset to determine the connection state at this time. If the connection state at this time is connected, it means that the connection of the stabilizing component 100 is stable at this time, and the grounding connection structure is grounded;

[0066] If the connection state is disconnected at this time, the connection counter is further used to accumulate the count according to the set parameters to determine whether the grounding device is always in a stable state each time the cumulative count is added. If so, the grounding structure is grounded, otherwise it is not grounded.

[0067] Under the premise that the circuit needs to be detected, that is, the connection state of the detection circuit is disconnected, the connection of the grounding device in the above embodiment is completed. At this time, the moving contact 104a is in contact with the static contact 104b. After the two contacts are in contact, since the inside of the grounding device is in a sealed state, it is impossible to determine whether the connection between the movable conductor 103b and the mounting rod 101d is reliable, that is, there may be damage to the components, or the two conductors are briefly in contact due to various force majeure factors, resulting in the phenomenon of grounding. Although the circuit can be turned on, the grounding state cannot be maintained for a long time. At this time, the MSP430G2553 control chip timer is turned on. When the accumulated timing reaches a certain set threshold, the contact between the static contact 104b and the moving contact 104a is still in a closed state. At this time, the counter 2 is reset, that is, the disconnection counter (the counter used for counting when the two contacts are disconnected) is reset. If the connection state at this time is connected, the grounding terminal is connected, and the working state of the grounding device is normal, indicating that the connection at this time is reliable;

[0068] If the connection status is detected to be disconnected at this time, it may be due to poor contact or the MSP430G2553 control chip has not been detected temporarily. At this time, counter 1, that is, the connection counter (the counter used to count when the two contacts are connected) starts counting. The counter is increased by 1 when the circuit is turned on. If the counter reaches the preset count value at this time, it means that the circuit is still stably connected at this time, so the connection at this time is reliable. If the number of circuit conductions does not reach the preset value within a certain period of time, the connection state at this time is unstable. Then return to the timer to check whether the circuit at this time can still maintain the static contact closed state within a certain period of time; the opposite is true for disconnection.

[0069] In summary, by setting timer 1 or timer 2, that is, the threshold of the connection timer and the disconnection timer, it is judged whether the grounding device is in a stable connection state at this time through the connection time of the whole circuit. After the circuit is connected or disconnected to a certain extent, it is judged that the circuit is stable whether it is connected or disconnected at this time, which means that the next series of work can be carried out, otherwise it means that the circuit lacks stability at this time.
