Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to a GPS positioning automatic detection vertical hanging type ground wire hanging head and a use method thereof. Background Art

[0002] When inspecting and repairing power lines, it is necessary to first use a grounding wire to ground the power conductor, and then conduct detailed inspection and maintenance on it. The grounding wire currently used generally includes a grounding wire body and a hanging head, and a hanging head ring is provided on the hanging head.

[0003] The utility model patent with the authorization announcement number CN204497406U discloses a high-voltage overhead line protective grounding wire, including a hanging head and an insulating operating rod, the hanging head and the insulating operating rod are connected by a connector, the connector includes an upper connecting part and a lower connecting part, the lower connecting part is fixedly connected to the insulating operating rod, and the hanging head is connected to the upper connecting part with a single degree of freedom rotation, so that the hanging head can move left and right with an offset from the axis of the insulating operating rod. And its hanging head is J-shaped, and a double-tongue spring clip for clamping the wire is provided inside. When in use, the operator holds the insulating operating rod, lifts the hanging head above the wire, and then pulls the insulating operating rod hard to squeeze the wire between the two spring clips to complete the connection between the wire and the grounding wire.

[0004] However, during the implementation of the above technical solution, since the two tongue-type spring clips are tightly abutted under normal conditions, the wire is not easy to get stuck between the two tongue-type spring clips when in use, and the operator needs to pull hard to complete the connection operation; and in this technical solution, a cavity is left between the two tongue-type spring clips near the end of the hanging head. In this way, when the diameter of the wire to be tested is small, it is inserted into the cavity and the connection with the hanging head is unstable, which affects the personal safety of the operator and makes the test result inaccurate. Summary of the invention

[0005] The first purpose of the present invention is to provide a GPS positioning automatic detection vertical ground wire hanging head, which can conveniently make the wire clip into the head body when connected with the wire, and at the same time, improve the stability of the connection between the head body and the wire.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A GPS positioning automatic detection hanging ground wire hanging head, comprising a ground wire and a hanging head body arranged at one end thereof, the hanging head body is J-shaped, and is provided with a double-tongue spring clip therein, the ground wire is connected to an end wall of the hanging head body, the end of the hanging head body away from the ground wire is provided with a connecting ring, an insulating pull rope is connected to the connecting ring, and a main valve spring for propping open the two tongue-type spring clips is rotatably provided between the two tongue-type spring clips. Further,

[0008] Furthermore, one end of the two tongue-type spring clips is respectively rotatably connected to the open end of the hanging head body, one end of the main valve spring is rotatably connected to one of the tongue-type spring clips away from the open end of the hanging head body, and the other free end is movably abutted against the outer wall of the tongue-type spring clip on the opposite side.

[0009] Furthermore, the outer wall of the tongue-type spring clip abutting against the free end of the main valve spring is provided with a groove matching with the main valve spring.

[0010] Furthermore, an induction electrometer for detecting the current flux of the hanging head body is provided on the outer wall of the hanging head body.

[0011] Furthermore, a GPS locator is provided on the hanging head body.

[0012] Furthermore, a V-shaped pressure switch for controlling the operation of the GPS locator is provided between the tongue-type spring clip and the hanging head body, and connecting plates are respectively provided on two opposite surfaces of the pressure switch. One end arm of the pressure switch is connected to the hanging head body, and the other end arm is connected to the tongue-type spring clip.

[0013] Furthermore, the pressure switch is connected to the tongue-type spring clip via a spring.

[0014] Furthermore, one end of the tongue-type spring clip away from the opening end of the hanging head body is connected to the hanging head body through a conductive soft belt.

[0015] Furthermore, two end surfaces of the opening end of the hanging head body are respectively provided with guiding inclined surfaces opposite to each other.

[0016] The second object of the present invention is to provide a method for using a GPS positioning automatic detection hanging type ground wire hanging head, comprising the following steps:

[0017] S1: Pull the two tongue-type spring clips apart and move them away from each other;

[0018] S2: Make the free end of the main valve spring fit into the groove of the tongue-type spring clip on the opposite side;

[0019] S3: Hold the insulating rope and pull the head body to the top of the wire to be tested;

[0020] S4: Release the restriction on the insulating pull rope, so that the head body falls under the action of gravity, the wire is stuck in the head body, the main valve spring abuts against the top of the wire, and rotates upward under the push of the wire, thereby releasing the restriction of the main valve spring on the tongue spring clip, and the two tongue spring clips are relatively close, squeezing the wire and fixing it between the two tongue spring clips;

[0021] S5: When the two tongue-type spring clips are relatively close to each other, the spring squeezes the V-shaped pressure switch, the two connecting pieces come into contact, and the GPS locator is started to detect whether the geographical location of the head body at this time is consistent with the predicted geographical location of the wire to be tested;

[0022] S6: The induction tester detects whether there is current passing between the two tongue-type spring clips to determine whether the object being tested is a wire.

[0023] The present invention has the following beneficial effects:

[0024] 1. The present invention arranges a main valve spring between two tongue-type spring clips for holding the two tongue-type spring clips apart, so that a space for clamping the wire is reserved in advance between the two main valve springs, so that the wire can be smoothly clamped between the two tongue-type spring clips when the wire is connected. At the same time, one end of the main valve spring is rotatably connected to one of the tongue-type spring clips, and the other end abuts against the outer wall of the tongue-type spring clip on the opposite side, and a groove matching the end of the main valve spring is provided on the outer wall, so that the main valve spring can hold the two tongue-type spring clips apart more stably, avoiding the two tongue-type spring clips from closing before the wire is hung in the hanging head body, which affects the working efficiency of the wire connection operation. Moreover, when the hanging head body of the present invention is in use, it is only necessary to lift the hanging head body to the top of the wire to be tested by the insulating pull rope when the two tongue-type spring clips are stretched open. After that, the insulating pull rope is loosened, the hanging head body falls under the action of gravity, the wire is stuck in the hanging head body, the main valve spring abuts against the top of the wire and rotates upward under the pushing action of the wire, thereby releasing the restriction of the main valve spring on the tongue-type spring clip. The two tongue-type spring clips are relatively close to each other under the action of the torsion spring, squeezing the wire and fixing it between the two tongue-type spring clips, completing the connection of the wire. When it is necessary to release the connection between the hanging head body and the wire, it is only necessary to pull the insulating pull rope hard, and the wire can be detached from between the two tongue-type spring clips. The operation is convenient, the wire connection and disconnection operations are simple and quick, and the wire connection has high stability.

[0025] 2. By setting a GPS locator and a V-shaped pressure switch to control its operation on the hanging head body, when the two tongue-type spring clips are stretched open by the main valve spring, the two connectors on the pressure switch do not touch, and the GPS locator does not work at this time. When the wire is inserted into the hanging head body, the two tongue-type spring clips are close to each other, and the two connectors on the pressure switch touch, and the GPS locator is controlled to work to detect whether the geographical location of the hanging head body at this time is consistent with the predicted geographical location of the wire to be tested. If it is consistent, it is preliminarily judged as the wire to be tested; if it is not consistent, the object to be tested is not the wire to be tested, and the operator pulls the insulating rope by hand. Since the outer wall of the tongue-type spring clip is arc-shaped, the object to be tested can slide out smoothly from between the two tongue-type spring clips, and the wire connection operation can be carried out again. The GPS locator can help improve the accuracy of the wire connection operation.

[0026] 3. The present invention sets an induction electrometer on the hanging head body, and the induction electrometer detects whether there is current passing through the hanging head body to determine whether the measured object is a wire. If there is current passing through, the measured object is a wire; if there is no current, the measured object may not be the wire to be measured. After further inspection, the operator determines whether to reconnect the wire, thereby improving the work efficiency and accuracy of the wire connection operation.

[0033] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention discloses a GPS positioning automatic detection hanging type ground wire hanging head, referring to Figure 1 and Figure 2 As shown, it includes a grounding wire 1 and a head body 2 fixedly connected to one end thereof. When in use, one end of the grounding wire 1 with the head body 2 is connected to the conductor 8 to be tested, and the other end is connected to the iron tower fixed to the ground, and then the conductor 8 to be tested is tested in detail.

[0035] Reference Figure 1 and Figure 2 In this embodiment, the head body 2 is J-shaped, and the grounding wire 1 is connected to its longer end arm; a connecting ring 3 is fixedly connected to the outer wall of the arc end of the head body 2, and an insulating pull rope 31 is detachably connected to the connecting ring 3. Guide slopes 21 are respectively arranged on the two end surfaces of the open end of the head body 2, so that the wire 8 can be prevented from being stuck at the end of the head body 2, and the wire 8 can be more easily slid into the head body 2.

[0036] Reference Figure 1 and Figure 2 A double tongue spring clip 4 is rotatably arranged in the head body 2. The end of each tongue spring clip 4 near the open end of the head body 2 is rotatably connected to the head body 2 through a rotating shaft, and the middle part of each tongue spring clip 4 is connected to the head body 2 through a torsion spring 41 fixed to the inner wall of the corresponding head body 2. The ends of the two tongue spring clips 4 away from the open end of the head body 2 are in a free state, so that they can approach or move away from the head body 2. The arc end of the head body 2 and the two sides of the connecting ring 3 are respectively provided with a clearance groove 22 that cooperates with the corresponding tongue spring clip 4. When the tongue spring clip 4 rotates relative to the head body 2, it moves in the clearance groove 22. The end of the tongue spring clip 4 near the clearance groove 22 is connected to the outer wall of the head body 2 through a conductive soft belt 43, and the conductive soft belt 43 is set through the clearance groove 22.

[0037] Reference Figure 1 and Figure 2 A main valve spring 5 for spreading the two tongue-type spring clips 4 is rotatably connected between the two tongue-type spring clips 4. In this embodiment, the main valve spring 5 is arc-shaped, and its bending direction is consistent with the bending direction of the arc end of the hook body 2. The free end of the tongue-type spring clip 4 located on the longer end arm side of the J-shaped hook body 2 is rotatably connected to one end of the main valve spring 5; a groove 42 is provided on the outer wall of the tongue-type spring clip 4 on the opposite side, and the other end of the main valve spring 5 is movably abutted in the groove 42.

[0038] Reference Figure 2 and Figure 4The outer wall of the head body 2 is provided with an induction electroscope 6. When testing the wire 8, the wire 8 is inserted between the two tongue-type spring clips 4. At this time, the current is transmitted to the ground wire 1 through the tongue-type spring clips 4 and the conductive soft belt 43. The induction electroscope 6 can detect whether there is current passing through the head body 2 to help determine whether the object to be tested is the wire 8 and the power supply condition of the wire 8. In this embodiment, the double-tongue-type spring clips 4 are used to clamp the wire 8, so as to improve the stability of the connection between the head body 2 and the wire 8 and improve the accuracy of the detection result. The induction electroscope 6 belongs to the prior art, and its internal circuit is not described here.

[0039] Reference Figure 3 and Figure 4 A GPS locator 7 is also arranged on the outer wall of the head body 2, and a V-shaped pressure switch 71 for controlling the operation of the GPS locator 7 is arranged between the end of the tongue-type spring clip 4 close to the main valve spring 5 and the head body 2. In this embodiment, connecting pieces 72 are respectively attached to the two opposite surfaces of the pressure switch 71, one end arm of the pressure switch 71 is connected to the inner wall of the yielding groove 22 close to the connecting ring 3, and the other end arm is connected to the outer wall of the tongue-type spring clip 4 through a spring 73. The GPS locator 7 belongs to the prior art, and its internal circuit is not described here.

[0040] The present invention also discloses a method for using the above-mentioned GPS positioning automatic detection hanging type ground wire hanging head, which specifically includes the following steps.

[0041] S1: When it is necessary to use the GPS positioning to automatically detect the connection between the hanging head of the hanging ground wire 1 and the conductor 8, the operator first manually pulls the two tongue-type spring clips 4 apart to move them back to back.

[0042] S2: The free end of the main valve spring 5 is inserted into the groove 42 of the tongue-type spring clip 4 on the opposite side, and the two tongue-type spring clips 4 are spread apart to leave space for clamping the wire 8 .

[0043] S3: The operator holds the insulating pull rope 31 and pulls the head body 2 to the top of the conductor 8 to be tested.

[0044] S4: The operator releases the restriction on the insulating pull rope 31, allowing the hanging head body 2 to fall under the action of gravity, and the wire 8 is stuck in the hanging head body 2. The main valve spring 5 abuts against the top of the wire 8 and rotates upward under the push of the wire 8, thereby releasing the restriction of the main valve spring 5 on the tongue-type spring clip 4. The two tongue-type spring clips 4 are relatively close to each other under the action of the torsion spring 41, squeezing the wire 8 and fixing it between the two tongue-type spring clips 4.

[0045] S5: When the two tongue-type spring clips 4 are relatively close to each other, the spring 73 squeezes the V-shaped pressure switch 71, and the two connecting pieces 72 are in contact. The GPS locator 7 is activated to detect whether the geographical location of the head body 2 at this time matches the geographical location of the predicted wire 8 to be tested. If it matches, it is preliminarily determined to be the wire 8 to be tested; if it does not match, the object to be tested is not the wire 8 to be tested, and the operator pulls the insulating pull rope 31 by hand. Since the outer wall of the tongue-type spring clip 4 is in an arc shape, the object to be tested can slide out smoothly from between the two tongue-type spring clips 4, and the wire 8 connection operation is re-performed.

[0046] S6: The induction tester 6 detects whether there is current flowing through the hanging head body 2, and determines whether the object to be tested is the wire 8. If there is current flowing through, the object to be tested is the wire 8; if there is no current, the object to be tested may not be the wire 8 to be tested, and the operator makes further inspection and determines whether to reconnect the wire 8.
