[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0037] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0039] The present utility model provides a ground wire state detection device. Referring to Figures 1 to 4 , the ground wire state detection device includes a ground wire clip 1, a trigger assembly 2, and a detection component 3. The ground wire clip 1 has a receiving area for receiving a grounding cable, and the ground wire clip 1 is used for clamping the grounding cable.

[0040] Both the trigger assembly 2 and the detection component 3 are provided on the ground wire clip 1. The trigger assembly 2 and the detection component 3 are trigger-matched. A part of the trigger assembly 2 is movably disposed in the receiving area. The trigger assembly 2 has a trigger position and a non-trigger position. When the ground wire clip 1 is not connected to the ground wire, the trigger assembly 2 is in the non-trigger position, and the trigger assembly 2 does not trigger the detection component 3. When the ground wire clip 1 is properly connected to the ground wire, the trigger assembly 2 is in the trigger position and can trigger the detection component 3, so that the detection component 3 can detect that the ground wire clip 1 and the ground wire are properly connected.

[0041] Based on the above scheme setting, a triggering component 2 and a detecting component 3 are arranged on the ground wire clamp 1, so as to be able to realize real-time detection of the state of the ground wire, such as real-time detection of whether it is properly connected, whether it is wrongly connected or whether it is removed, etc. It can also restrict and standardize the connection operation, so that the effectiveness of the connection can be effectively guaranteed, the connection reliability is high, and the connection operation is convenient, and the operation safety is well guaranteed, effectively reducing potential safety hazards and greatly reducing the possibility of power safety accidents.

[0042] Among them, the detecting component 3 can be a contact switch, such as a micro switch, a contact sensor, etc.; the detecting component 3 can also be a non-contact switch, such as an optoelectronic switch, a displacement sensor, etc. It can be understood that the detecting component 3 can be communicatively connected to the remote terminal device through a circuit structure such as a circuit board, so as to be able to realize remote detection of the connection state of the ground wire.

[0043] A buzzer can be arranged on the circuit structure. When the detecting component 3 detects that the ground wire clamp 1 is connected to the grounding cable, the buzzer alarms to play a prompting role, so as to realize intelligent detection of the connection state. In addition, an indicator light can also be arranged on the circuit structure. When the detecting component 3 detects that the ground wire clamp 1 is connected to the grounding cable, the indicator light flashes to play a prompting role.

[0044] Refer to Figures 1 to 7 , the ground wire clamp 1 includes a first clamp body 11, a second clamp body 12, an elastic member 13 and a locking component 14. Among them, the first clamp body 11 and the second clamp body 12 are hingedly connected, the locking component 14 is connected to the second clamp body 12, the elastic member 13 is arranged adjacent to the hinge point of the first clamp body 11 and the second clamp body 12, one end of the elastic member 13 is connected to the first clamp body 11, and the other end is connected to the locking component 14.

[0045] The locking component 14 has a locked state and an unlocked state. In the locked state, the elastic member 13 is in a stretched state, and the first clamp body 11 and the second clamp body 12 are closed to clamp the grounding cable; in the unlocked state, the first clamp body 11 and the second clamp body 12 are opened to release the grounding cable.

[0046] Set like this to ensure that the grounding cable can be stably clamped, effectively avoiding the phenomenon of improper connection or loose connection, which helps to improve the triggering sensitivity of the triggering component 2, ensure that the triggering component 2 can effectively trigger the detecting component 3 to work, and thus improve the detection accuracy of the detecting component 3 for the connection state of the ground wire.

[0047] The first clamp body 11 and the second clamp body 12 are arranged in a hook shape. The length of the first clamp body 11 is less than that of the second clamp body 12. The first clamp body 11 has a first clamping wall, and the second clamp body 12 has a second clamping wall. Both the first clamping wall and the second clamping wall are arranged in an arc shape to adapt to the external shape of the grounding cable. The first clamping wall and the second clamping wall are used to jointly clamp or release the grounding cable.

[0048] Among them, the elastic member 13 can be a spring or other structural members with elastic properties.

[0049] Continue to refer to Figures 1 to 7 , the trigger assembly 2 includes a trigger member 21, the trigger member 21 is rotatably connected to the second clip body 12, the trigger member 21 has an abutting portion 211 and a trigger portion 212, the trigger portion 212 is arranged inside the second clip body 12 and is in trigger cooperation with the detection member 3, the abutting portion 211 extends outside the second clip body 12 and is located in the accommodation area, and at the trigger position, the abutting portion 211 is acted on by an external force to drive the trigger portion 212 to trigger the detection member 3.

[0050] The detection member 3 is fixedly installed inside the second clip body 12 by screws and is correspondingly arranged with the trigger portion 212. A long strip hole is opened on one side of the second clip body 12 facing the first clip body 11, and the long strip hole allows the abutting portion 211 to pass through, so that the abutting portion 211 can extend outside the second clip body 12. The abutting portion 211 has a contact wall facing the first clip body 11, and the contact wall is arranged in an arc shape, so that when hanging the grounding cable, the grounding cable can effectively drive the trigger member 21 to rotate, so as to be able to trigger the detection member 3 to work, thereby realizing the real-time detection of the hanging state of the ground wire.

[0051] The trigger assembly 2 further includes a reset member 22, the reset member 22 is arranged inside the second clip body 12, one end of the reset member 22 is connected to the second clip body 12, and the other end abuts against the trigger member 21. The reset member 22 is used to provide a reset restoring force for the trigger member 21. When the ground wire clip 1 hangs the grounding cable, the grounding cable presses against the abutting portion 211, thereby driving the trigger member 21 to compress the reset member 22; when the grounding cable is removed, the trigger member 21 is not acted on by an external force, and the reset member 22 provides a reset restoring force for the trigger member 21, so that the abutting portion 211 is reset.

[0052] With such a setting, the possibility of the trigger member 21 getting stuck during reset is effectively reduced, and the smoothness of the reset of the trigger member 21 can be well improved, so as to ensure the reliability of the detection of the hanging state when hanging the ground wire next time.

[0053] Among them, the reset member 22 can be a spring or other structural members with elastic properties.

[0054] Continue to refer to Figures 1 to 7, the trigger member 21 includes a mounting body 213 and a trigger body 214. The mounting body 213 is rotatably connected to the second clamping body 12. The trigger body 214 is fixed on the mounting body 213. The trigger portion 212 is formed on the mounting body 213, and the abutting portion 211 is formed on the trigger body 214. The ground wire state detection device further includes a control board 4 disposed in the second clamping body 12. The mounting body 213 is an insulator, and the first clamping body 11, the second clamping body 12, and the trigger body 214 are all conductors. The trigger body 214 is in insulating contact with the second clamping body 12, and both the trigger body 214 and the second clamping body 12 are electrically connected to the control board 4. At the trigger position, if the grounding cable is a metal cable, an electrical circuit can be formed between the trigger body 214 and the second clamping body 12.

[0055] Since the first clamping body 11, the second clamping body 12, and the trigger body 214 are all conductors, when the grounding cable is clamped on the ground wire clamp 1, the grounding cable can conduct the electrical circuit between the trigger body 214 and the second clamping body 12, so the control board 4 determines that the grounding cable is a metal cable, otherwise it is a non-metal cable.

[0056] Specifically, a first circuit terminal 121 is provided in the second clamping body 12, and a second circuit terminal 215 is provided at one end of the trigger body 214 extending into the second clamping body 12. Both the first circuit terminal 121 and the second circuit terminal 215 are electrically connected to the control board 4 through wires. The control board 4 is integrated with an indicator light. When the electrical circuit between the trigger body 214 and the second clamping body 12 is conducted, the indicator light flashes. If the indicator light is green, it is determined that the grounding cable is a metal cable. If the indicator light is red, it is determined that the grounding cable is a non-metal cable. This is set to facilitate the operation of the operator and improve the reliability of the hanging operation.

[0057] It can be understood that the trigger body 214 is fixedly installed on the mounting body 213 by screws. Among them, the screws are provided with insulating gaskets, so that the trigger body 214 is in insulating contact with the second clamping body 12. The mounting body 213 can also be a housing structure. The trigger body 214 is partially embedded in the mounting body 213. The mounting body 213 is rotatably connected to the second clamping body 12 by screws, and this can also achieve the insulating contact between the trigger body 214 and the second clamping body 12.

[0058] Continue to refer to Figures 1 to 7, the ground wire status detection device further includes an electronic control component and an electrical box 6. The electronic control component is installed inside the electrical box 6, and the electrical box 6 is fixed to the lower end of the second clamp body 2. The electronic control component includes a control board 4, and the control board 4 is electrically connected to the detection component 3. The control board 4 is also integrated with a communication module so that the control board 4 can communicate with a remote terminal. The second clamp body 12 is provided with a first installation cavity 122 and a second installation cavity 123 which are arranged at intervals. The battery 5 is arranged in the first installation cavity 122, and both the control board 4 and the detection component 3 are electrically connected to the battery 5. The second installation cavity 123 has an opening. The control board 4 is installed inside the electrical box 6, and the electrical box 6 is installed inside the second installation cavity 123 and covers the opening of the second installation cavity 123. Among them, the control board 4 is integrated with a communication module, and the communication module can communicate with a remote terminal.

[0059] With such a setting, the first installation cavity 122 and the second installation cavity 123 can divide the area to install the control board 4 and the battery 5, making the overall structure of the ground wire status detection device compact and facilitating subsequent battery 5 replacement or control board 4 maintenance.

[0060] Among them, the first installation cavity 122 has an opening. The ground wire status detection device may further include a battery 5 cover and a sealing gasket 52. The battery 5 cover is installed at the opening of the first installation cavity 122 and is threadedly connected to the cavity wall of the first installation cavity 122. The sealing gasket 52 is sleeved on the outer peripheral wall of the battery 5 cover. The sealing gasket 52 is used to seal the gap between the battery 5 cover and the cavity wall of the first installation cavity 122 to play a waterproof role, protect the battery 5, ensure the normal use of the ground wire status detection device, and improve the stability of the ground wire status detection device in use.

[0061] The control board 4 is integrated with a buzzer, and the electrical box 6 is provided with a mesh hole, and the buzzer is arranged corresponding to the mesh hole. The ground wire status detection device may further include a waterproof sleeve 7, and the waterproof sleeve 7 is sleeved on the buzzer to play a waterproof role. The waterproof sleeve 7 is provided with a plurality of small holes to allow sound waves to be transmitted outward.

[0062] The control may also be integrated with at least one of a positioning module and a voice module. The specific module components integrated on the control board 4 can be set according to needs. In this embodiment, both the positioning module and the voice module are set, and the effects of positioning and voice reminder alarm can be achieved.

[0063] The ground wire status detection device further includes a seal 8, and the seal 8 is arranged inside the second clamp body 12. The seal 8 is used to seal the gap between the electrical box 6 and the second clamp body 12.

[0064] Specifically, the seal 8 is arranged at the bottom of the second installation cavity 123. One end of the electrical box 6 facing the second installation cavity 123 has a pressing end 61, and the pressing end 61 presses on the seal 8. The seal 8 is used to seal the gap between the pressing end 61 and the cavity wall of the second installation cavity 123.

[0065] With such a setting, it effectively prevents external liquid from entering the electrical box 6, thereby effectively protecting the control board 4, ensuring that the ground wire state detection device can be used normally, and reducing the risk of malfunction.

[0066] The seal 8 can be a silicone seal ring or a rubber seal ring, or other structural members that can play a sealing role.

[0067] Continue to refer to Figures 1 to 7 , on the side of the second clip body 12 facing away from the first clip body 11, a guiding slot 124 is provided. The guiding slot 124 is communicated with the internal space of the second clip body 12. The locking assembly 14 includes a first locking member 141 and a second locking member 142. The first locking member 141 and the second locking member 142 are arranged at intervals and are both rotatably connected to the second clip body 12. One ends of the first locking member 141 and the second locking member 142 are arranged inside the second clip body 12, and the other ends both pass through the guiding slot 124 and extend outside the second clip body 12.

[0068] The first locking member 141 is arranged near the hinge point of the first clip body 11 and the second clip body 12 and is connected to the elastic member 13; the first locking member 141 is provided with a first clamping portion 1411, and the second locking member 142 is provided with a second clamping portion 1421. In the locked state, the first clamping portion 1411 and the second clamping portion 1421 are clamped and matched to limit the rotation of the first locking member 141; in the unlocked state, the first clamping portion 1411 and the second clamping portion 1421 are disengaged from the cooperation.

[0069] With such a setting, under the action of the first locking member 141 and the second locking member 142, it is ensured that the first clip body 11 and the second clip body 12 can stably clamp the grounding cable, so that the grounding cable is not easily separated from the ground wire clip 1, ensuring the stability and standardization of the hanging operation, and effectively reducing the possibility of safety accidents.

[0070] Both the first locking member 141 and the second locking member 142 are bent. One end of the first locking member 141 extending outside the second clip body 12 is provided with a pressing boss 1412. The operator can conveniently press the first locking member 141 by pressing the pressing boss 1412 to drive the first locking member 141 to rotate, thereby stretching the elastic member 13. Both the first clamping portion 1411 and the second clamping portion 1421 can be hook structures, or can be other structural members with a pairwise buckling or clamping cooperation.

[0071] Among them, the second locking member 142 has a suspension hole 1413, and a suspension ring can be installed in the suspension hole 1413. A plurality of suspension ring mounting parts are provided at one end of the second clip body 12 away from the first clip body 11. A part of the plurality of suspension ring mounting parts can be mounting holes 125, and the other part can be hooks 126. In this way, the ground wire state detection device can be hoisted and used, thereby improving the performance of the ground wire state detection device.

[0072] Continue to refer to Figures 1 to 7 , the locking assembly 14 further includes a return member 143 disposed in the second clip body 12. One end of the return member 143 is connected to the second clip body 12, and the other end abuts against the second locking member 142. The return member 143 is used to provide a return force for the second locking member 142 to return.

[0073] In the unlocked state, the return member 143 elastically supports the second locking member 142. The operator presses the first locking member 141 by pressing the boss 1412, so that the first engaging portion 1411 moves toward the second locking member 142. The first locking member 141 presses against the second locking member 142, so that the second locking member 142 compresses the return member 143 until the first engaging portion 1411 engages with the second engaging portion 1421. When unlocking is required, press the second locking member 142, so that the second locking member 142 continues to compress the return member 143 until the first engaging portion 1411 is disengaged from the second engaging portion 1421, then the unlocking of the first locking member 141 and the second locking member 142 can be achieved.

[0074] With such a setting, the return member 143 can not only provide a return force for the second locking member 142 to return, ensure the smoothness of the reset of the second locking member 142, but also enhance the engaging force and stability between the first engaging portion 1411 and the second engaging portion 1421, so as to improve the stability of locking the first clip body 11 and the second clip body 12 and enhance the performance of the ground wire state detection device.

[0075] Among them, the reset member 22 can be a spring or other structural members with elastic properties.
