Connection, the assembly of wireless signal transceiver, that is, wireless signal receiver and wireless signal transmitter are sent out for receiving controller 3
Control information out and the numerical value change situation to 3 feedback pressure sensor of controller, can be easy to implement remote operation.
As shown in Figure 3 and Figure 4, the wire clamp end 1 includes the hook 104 of Qian character form structure and is rotatably connected on hook 104
The standing screw 105 of lower end surface, and the standing screw 105 is through the lower end surface of the hook 104；The standing screw 105
The one end for penetrating the hook 104 is rotatably connected to fixed plate 106,104 hook 104 of side and hook of the fixed plate 106
The lateral surface of inner concave be slidably connected；The inside of 104 inner concaves of the hook is arranged in first electronic lock 101；It is described
104 one sides opposite with fixed plate 106 of hook are arranged in first pressure sensor 102.
Fixed plate 106 is able to drive by the standing screw 105 of rotation setting to rise or fall, and fixed plate 106 is slided
It is connected to hook above and is rotatablely connected with standing screw 105, therefore can be avoided and fixed plate is being driven by standing screw 105
When 106 movement, the problem of fixed plate 106 can be made to rotate, can pass to guarantee the safety of its ground connection in first pressure
The sheet metal connecting with hook 104 is set, therefore on sensor 102 when installing wire clamp end 1, can be realized wire clamp end 1 and transmission of electricity
Being stably connected between cable, and first pressure sensor 102 then gives the pressure of sheet metal by detecting power transmission cable, comes real
Now to the detection of wire clamp end installation condition, it can be avoided first pressure sensor 102 and directly contacted with power transmission cable and easily connect
Touch bad problem.
As shown in Figure 3 and Figure 4, first electronic lock 101 includes mounting plate 107 and moves for drive installation plate 107
Electric pushrod 108, the gag lever post 109 of several spaced sets, the gag lever post are slidably connected on the mounting plate 107
109 one end far from fixed plate 106 are provided with the tension spring 110 connecting with mounting plate 107, are able to drive by electric pushrod 108
The movement of mounting plate 107, the movement of mounting plate 107 then will drive the movement of gag lever post 109, and mounting plate, which continues movement, can then make and fix
The meeting stop motion of the corresponding gag lever post 109 of plate 106, and remaining gag lever post 109 then will continue to move, and is allowed to be in and blocks fixation
The state of plate 106, to realize the purpose locked to fixed plate 106.
You need to add is that the ground terminal 2 is identical as the structure at wire clamp end 1, it can be improved in the event of its failure
Versatility between accessory can substantially increase the applicability of the ground line.
The state that ground line is determined by controller 3 opens the second electronic lock 201 according to the information for being judged to being grounded installation
Installation ground terminal 2 is carried out, the connection state information of ground terminal 2 and ground stud is detected by second pressure sensor 202, by the
Detected connection state information is sent to controller 3 by two wireless signals, 203 transceiver, is carried out logic by controller 3 and is sentenced
Disconnected, according to successful result is judged to the second electronic lock 201 transmission unlocking signal, the second electronic lock 201 receives unlocking information solution
Locking wire presss from both sides end 1, installs wire clamp end 1 and detects 1 connection status of wire clamp end by first pressure sensor 102, passes through the first wireless communication
1 connection state information of wire clamp end is fed back to controller 3 by number transceiver 103, logic judgment is carried out by controller 3, according to judgement
Successful result issues grounding wire mounting and sets pass signal.
You need to add is that the installation steps of the ground line demounting procedure and ground line in disassembly on the contrary, be grounded
When, benefit can be realized in the same way controls ground terminal and wire clamp end in disassembly process, can be avoided and is dismantling
In the process, worker does not operate according to safety operation process, leads to the problem of causing danger.
Determine the concrete mode of the ground line status are as follows:
Controller 3 receives the information of first pressure sensor 102 and second pressure sensor 202, judges wire clamp end 1 and connects
The installation condition of ground terminal 2；
Wire clamp end 1 and ground terminal 2 are in installation condition, then when being operated, are judged to dismantling ground line；
Wire clamp end 1 and ground terminal 2 are in non-installation condition, then when being operated, are judged to installing ground line.
After the controller 3 determines that ground terminal 2 is installed successfully, controller 3 sends to the second electronic lock 201 and locks signal；
After the controller 3 determines that wire clamp end 1 is installed successfully, controller 3 sends to the first electronic lock 101 and locks letter
Number.
I.e. after installation, the locking at docking line end 2 or wire clamp end 1 is realized by electronic lock, can be installed to it
The step of while be defined, additionally it is possible to realize that it is installed and carry out secondary fixation, can be avoided it and unexpected fall off occur
The problem of.
The controller 3 include for judge the ARM microcontroller 301 of 1 connection state information of ground terminal 2 and wire clamp end,
Third wireless signal transceiver 303 and indicator light 302, the ARM microcontroller 301 and 303 electricity of third wireless signal transceiver
Property connection, and the third wireless signal transceiver 303 by wireless signal respectively with the first wireless signal transceiver 103 and the
The connection of two wireless signal transceivers 203, there are two the settings of indicator light 302, and two indicator lights 302 are respectively used to show
Show ground line mount message and ground line mount message, can be carried out using the indicator light 302 of setting convenient for administrative staff real-time
The case where supervision ground line installation, the safety of ground line installation and removal can be greatly improved.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
