Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It will be appreciated by those skilled in the art that features from the examples and embodiments described below may be combined with each other without conflict.
Because the existing earthing device is mostly finished products, and the holding capacity is large, the intelligent reminding function needs to be added under the condition that the existing structure and the appearance state of the earthing device are not changed, the device is improved or added on the limited and convenient basis, and the weight and the volume of the earthing device are correspondingly balanced with the function under the condition that the weight and the volume are slightly increased. The hidden danger and the accident caused by the negligence of the operating personnel are reduced or avoided in the operation of hanging the grounding wire.
Therefore, the intelligent judgment and reminding function is added, so that the hidden danger and the accident caused by the negligence of the operating personnel are reduced or avoided in the process of hanging the grounding wire. As shown in fig. 1 to 5, the intelligent ground clamp misoperation prevention device comprises:
ground clamp body 100: the grounding wire clamp body is provided with a grounding end interface 1, a lead end fixing interface 2 and a lead end interface 3, the grounding end interface, the lead end fixing interface and the lead end interface are respectively provided with a spring piece type touch switch, and the three spring piece type touch switches send out electric signals when the corresponding grounding end wire clamp 11, the corresponding grounding end positioning piece and the corresponding lead end wire clamp 13 are inserted or pulled out;
the circuit controller: the circuit controller is connected with the three elastic sheet type touch switches, and judges whether the working procedures are correct or not in the process of installing and removing the grounding wire clamp according to the electric signals;
an alarm device: when the circuit controller judges that the wiring sequence is wrong, a control signal is sent to the alarm, and the alarm sends out an alarm.
The elastic sheet type touch switch arranged on the grounding end interface and the elastic sheet type touch switch arranged on the wire end interface are connected in series to the circuit controller, and the wire end fixing interface is independently connected into the circuit controller. The alarm is preferably an audible alarm or other audible and visual type alarm.
Ground connection end interface and wire end interface are used for the save and accomodate the use at operation initial stage multiplexer utensil, in three interface, each interface all has a shell fragment formula touch switch, because of the structural constraint when the installation with demolish the in-process, the fastener will inevitably take place the touching with the kneck switch, the switch sends the signal of telecommunication to circuit controller this moment, circuit controller accomplishes the judgement to the process according to the signal of telecommunication, with this completion installation and the voice prompt who demolishs the in-process, in order to reach the prevention occurence of failure and guarantee the ability of safe operation.
As shown in fig. 4, it is an initial state of the misoperation prevention device for the intelligent grounding clamp of the present invention, wherein the micro-motion wiring mode at the grounding end interface 1 in the three interfaces is a normally closed point, and when the initial state is reached, the micro-motion is an open state because of being squeezed by the grounding end clamp 11; the micro-motion wiring mode at the wire end interface 3 is a normally open point, and the micro-motion is in a disconnected state due to the extrusion of the wire end clamp 13 in an initial state; the wiring mode of the microswitch at the fixed interface 2 of the lead end is a normally open point, and the interface is in an open state because the microswitch is not pressed by any device at the moment.
When the grounding wire hooking operation is carried out, the wire end clamp 13 needs to be hooked firstly, so that the wire end clamp 13 is taken out from the wire end interface 3 firstly, and then the grounding end clamp 11 is taken out from the grounding end interface 1. Because the operation mode is correct, the device will not send out voice alarm and prompt.
If the wire end clamp is taken out firstly in the operation process, at the moment, because the micro-motion at the wire end interface 3 is a normally open point and the switch attribute is limited by no device, the switch is bounced open, the micro-motion is in a connected state, at the moment, because the micro-motion and the micro-motion at the grounding end interface 1 are in a series state, and because the micro-motion at the grounding end is a normally closed point and is also in an open state when being extruded by the device, an electric signal is transmitted into the circuit controller, and because the operation sequence is wrong, the circuit controller controls the alarm to carry out voice prompt on the operation and informs the correct operation sequence and installation steps of the alarm.
After the installation is completed, the device is inserted downwards along the lead end fixing interface 2 to complete the fixing. After the installation is finished, the grounding end cannot be detached without detaching the device, so that when the grounding end is detached firstly for preventing misoperation during detachment, when the intelligent misoperation preventing device is pulled out, the wire end fixing interface 2 is in micro-motion connection, and the circuit controller receives the interface independent electric signal at the moment, sends a voice prompt to an operator, and prompts that a wire end clamp of the wire end is detached firstly.
Other embodiments of the present invention than the preferred embodiments described above, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, should fall within the scope of the present invention defined in the claims.
