Detailed Description
The following will clearly and completely describe the technical solutions 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 embodiments. 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.
Referring to fig. 1-4, the present embodiment provides a pressure detection type ground wire pressing mechanism capable of monitoring a wire hanging state, which includes a hook 1, a pressing mechanism 2 penetrates through the hook 1, a screw rod 3 is connected to one end of the bottom of the hook 1 through a thread, the pressing mechanism 2 includes a left fixing block 4 and a right fixing block 6, the left fixing block 4 and the right fixing block 6 are fixedly connected together through a screw, and the circuit is conveniently installed and fixed by using the pressing mechanism 2.
Install conducting block 5 in the middle of left side fixed block 4 and the right fixed block 6, adopt conducting block 5, whether effective detection articulates on the electric wire, prevent the mistake and hang, left side fixed block 4 and right fixed block 6 joint respectively is in 1 both sides of couple, left side fixed block 4 and right fixed block 6 install pressure sensor 7 in conducting block 5 bottom one end, carry out accurate pressure value through pressure sensor 7 and detect, pressure sensor 7 bottom fixed connection is on pressure sensor installation upper plate 8, 8 bottom fixedly connected with pressure sensor installation hypoplastron 9 of pressure sensor installation upper plate, 9 bottom joint have guide arm cap 10 of pressure sensor installation hypoplastron, guide arm cap 10 bottom one end is rotated and is connected with guide arm 11, 1 bottom one end threaded connection of couple is on guide arm 11, 11 one end threaded connection of guide arm has the screw, adopt built-in guide arm 11 structure, destroy internal signal detection cable when preventing to screw up the earth connection.
When the existing equipment is used, the grounding wire of the built-in control system is lifted and pressed through the rotary screw rod 3, the cable inside the screw rod 3 is easily influenced by rotating factors, and the cable is wound and then damaged, so that the loss of connection between each detection signal and the control system occurs, information cannot be transmitted in time, and the detection function is lost.
When the wire clamp is used, firstly, a hook 1 is hung on a high-voltage wire, a pressing mechanism 2 rises until the wire is pressed through rotating a screw 3, a left fixing block 4 and a right fixing block 6 are respectively clamped on two sides of the hook 1, the rotating motion is converted into linear motion, an inner guide rod cap 10 is fixed in the pressing mechanism 2, and a guide rod 11 is fixed relative to the pressing mechanism 2 during rotation, so that a signal detection cable penetrating through the inner part of the guide rod cap is prevented from being wound, smooth transmission of an inner signal is ensured, when the pressing mechanism 2 presses the wire, the screw 3 pushes the guide rod cap 10 to push a pressure sensor 7, the value of the pressure sensor 7 is transmitted to a control system arranged in a grounding wire, and the fact that the wire is not pressed is judged.
After the wire is pressed, the conducting block 5 and the upper hook 1 form a current loop through the wire penetrating through the middle, the loop is on, the fact that the grounding wire is successfully hung on the wire is indicated, the fact that the loop is not on indicates that the grounding wire is not effectively hung, and the grounding wire must be hung again, so that whether the grounding wire is hung on the wire is effectively detected, and mistaken hanging is prevented.
