Description

Technical Field

[0001] The present invention relates to the technical field of power lines, and in particular to a power line external damage protection device. Background Art

[0002] External damage to power lines refers to the damage to power lines in line corridors and protection areas due to human factors, construction and other factors. External damage to transmission lines can cause line disconnection, short circuit and other faults, resulting in power supply interruption and affecting users' normal power consumption. Existing technical methods usually strengthen power protection awareness by hanging warning signs and publicizing power laws and regulations, or installing online monitoring devices to prevent external damage and take snapshots. However, the existing cameras have not been maintained for a long time and their camera functions are blocked, making it impossible to effectively monitor. Existing camera monitoring is only a simple monitoring method and cannot protect the line when external force is applied by construction equipment. Often, power lines are still damaged.

[0016] From the above, the characteristics and advantages of the present invention are:

[0017] By using the pulling force of the stretching wire on the wire and the torque energy stored when the spring rotates, the stretching wire pulls the wire back to its original position when the mechanical device collides with the wire and leaves the wire. Compared with the prior art, which uses the elastic force of the wire itself to return to the original position, the wire may be damaged due to insufficient elastic force or uneven restoration of the position. The pulling component reduces the damage caused by excessive stretching or uneven force on the wire by controlling the pulling process, thereby improving the overall stability and safety of the power system.

[0018] The alarm component can trigger a buzzer when the wire is significantly deformed, quickly alerting the operator, so that evacuation measures can be taken at the early stage of the accident to reduce further damage to the wire. Compared with the prior art, which only relies on setting up reminder signs and cameras for monitoring, the alarm triggered by this device can remind the operator to quickly evacuate the construction equipment from the wire, reduce further pressure on the wire, and thus reduce damage to the wire and the pole. In addition, this device adopts a power storage triggering method. When there are many birds standing on the surface of the wire, causing the wire to be significantly deformed, the buzzer can also be triggered to drive away the birds and avoid damage to the wire and the pole.

[0019] The prompt component can automatically pop out the push plate after the wire is hit, so that the push rod moves from the inside of the hollow plate to the outside of the hollow plate. With the pointing function of the arrow, it helps the inspectors to quickly identify the wires that need to be inspected, reminds the inspectors that the wires have been hit, and prompts them to conduct a detailed inspection of the wires to improve the inspection efficiency. Compared with the traditional inspection method, the prompt component provides clearer inspection instructions, reduces the judgment and omissions of the inspectors, and improves the pertinence and efficiency of the inspection. Compared with relying on the subjective judgment of the inspectors, the relative position of the push rod provides objective and clear inspection instructions, reducing the possibility of human omissions.

[0020] The protective cover is installed above the insulator example to cover the insulator example, so that the protective cover can prevent pollutants such as dirt, dust, and bird droppings from directly contacting the protective cover. Compared with the prior art of directly exposing the insulator example to the environment, this method can reduce the accumulation of pollutants, prevent the insulation performance of the insulator example from being reduced due to dirt accumulation on the surface, slow down the corrosion process, increase the service life of the insulator example, and reduce the risk of electrical failure.

[0048] Further, such as Fig. 9 and Fig.11 As shown, the two driving gears 61 are rotatably connected to the fixed plate 64, and the rack 62 is fixedly connected to the outer wall of the large slider 65;

[0049] Further, such as Fig. 9 and Fig.11 As shown, the slide plate 67 is located in the slide groove 66 at one end away from the blocking plate 611, the large limit block 68 is composed of a triangular limit block and a trapezoidal limit block, the end of the compression spring 610 away from the slide plate 67 is fixedly connected to the blocking plate 611, the guide column 69 is slidably connected to the blocking plate 611, and the outer surface of the guide column 69 is fixedly connected with a card block, the card block is square, and the card block is in contact with the blocking plate 611, which is used to limit the displacement of the guide column 69.

[0050] Further, such as Fig.13 As shown, the slide plate 67 is slidably connected to the hollow plate 42, and the slide plate 67 can move horizontally to the inside of the hollow plate 42;

[0051] During operation: the device can prevent the wire 3 from being overstretched due to collision with construction equipment. The detailed steps are as follows:

[0052] When the construction equipment collides with the wire 3 and squeezes it, causing the wire 3 to be significantly deformed with the contact point as the center, the tension of the wire 3 increases, and the stretching wire 57 in the opposite direction to the direction in which the wire 3 is pushed to deform is pulled out synchronously with the wire 3, so that the winding rod 56 rotates clockwise, and the rotation of the winding rod 56 drives the rotating shaft 55 to rotate. During the rotation of the rotating shaft 55, the winding part of the clockwork spring 53 rotates clockwise with the rotating shaft 55, and the winding part of the clockwork spring 53 is stretched, thereby storing torque energy;

[0053] When the winding rod 56 rotates clockwise, the winding rod 56 drives the linkage column 58 and the synchronous wheel 1 59 to rotate clockwise. The synchronous wheel 1 59 makes the bevel synchronous gear 510 rotate clockwise together with the synchronous wheel 1 59 through the synchronous belt. The clockwise rotation of the bevel synchronous gear 510 makes the meshing bevel gear 511 rotate counterclockwise. The counterclockwise rotation of the bevel gear 511 makes the driving gear 61 rotate counterclockwise as well.

[0054] When the driving gear 61 rotates counterclockwise, the rack 62 meshed with the driving gear 61 drives the large slider 65 to move horizontally along the fixing plate 64 toward the direction away from the retaining plate 63. At the same time, the slide plate 67, the large limit block 68, the guide column 69, the compression spring 1 610 and the blocking plate 611 above the large slider 65 move horizontally together with the large slider 65. During the horizontal movement of the large slider 65 toward the direction away from the retaining plate 63, the vertical surface of the large limit block 68 gradually contacts the inclined surface of the rotating rod 613. When the rotating rod 61 When the inclined surface of the large stop block 68 contacts the triangular stop block in the large stop block 68, the triangular stop block of the large stop block 68 will squeeze the rotating rod 613, so that the rotating rod 613 rotates with the rotation connection with the support plate 612 as the axis, until the large stop block 68 is located behind the vertical surface of the blocking block 614. At this time, the rotating rod 613 is in a horizontal state, the vertical surface of the large stop block 68 is opposite to the vertical surface of the squeezing blocking block 614, the rotating rod 613 stops rotating, the blocking block 614 blocks the large stop block 68, and the rotating rod 613 remains stationary;

[0055] When the large limit block 68 is blocked by the blocking block 614, the large limit block 68 and the slide plate 67 at the bottom of the large limit block 68 stay in place, while the large slider 65 and the compression spring 1 610 above the large slider 65 continue to move horizontally. During this process, the large slider 65 drives the blocking plate 611 to continue to move, so the distance between the slide plate 67 and the blocking plate 611 gradually decreases, the guide column 69 moves horizontally along the blocking plate 611, and the compression spring 1 610 between the slide plate 67 and the blocking plate 611 is compressed;

[0056] As the large slider 65 moves horizontally, the inclined surface of the rotating rod 613 will gradually contact the inclined surface of the blocking plate 611. When the inclined surface of the rotating rod 613 contacts the inclined surface of the blocking plate 611, the blocking plate 611 lifts the rotating rod 613, so that the rotating rod 613 rotates counterclockwise around the rotating connection with the support plate 612. When the blocking plate 611 lifts the rotating rod 613, the large limit block 68 loses the obstruction of the blocking block 614. At this time, the stored force of the compression spring 1 610 reaches the maximum. As the obstruction of the blocking block 614 to the large limit block 68 disappears, the compression spring 1 610 will stretch and apply a thrust to the slide plate 67, so that the large limit block 68 and the slide plate 67 quickly move horizontally in the direction away from the blocking plate 611.

[0057] When the slide plate 67 moves horizontally quickly, it will enter the interior of the hollow plate 42. At this time, the electrode sheet 6701 on the outer wall of the slide plate 67 contacts the electrical contact 615 on the inner wall of the hollow plate 42, thereby triggering the buzzer 616 on the upper surface of the protective cover 4. The buzzer 616 emits a continuous alarm sound to remind the operator of the construction equipment that the construction equipment has collided with the wire 3 and exerted pressure on the wire 3, and please immediately operate the construction equipment away from the wire 3. Compared with the method of setting up warning signs or installing cameras for monitoring in the prior art, the camera has not been maintained for a long time and the camera function is blocked, and the problem of inability to effectively monitor is that the buzzer 616 emits a continuous alarm sound to remind the operator to operate the construction equipment to immediately leave the wire 3, so as to protect the wire 3 in time;

[0058] When many birds stand on the surface of the wire 3, the wire 3 will be obviously deformed. At this time, the wire 3 pulls the stretching wire 57, and the linkage column 58 rotates clockwise, driving the rack 62 to move to the inclined surface of the blocking block 614 contacting the blocking plate 611, and then repeating the above steps to trigger the buzzer 616 to emit a continuous alarm sound, effectively driving away the birds. Compared with the problem of the prior art that the camera is installed but the birds cannot be driven away, the alarm issued by the buzzer 616 can effectively drive away the birds standing on the surface of the wire 3, and prevent the wire 3 from being subjected to greater pressure and being damaged;

[0059] When the construction equipment is removed from the surface of the wire 3, the wire 3 can be pulled back to its original position. The detailed steps are as follows:

[0060] When the operator operates the construction equipment to gradually move away from the wire 3, the above steps are repeated in reverse. As the construction equipment gradually moves away from the wire 3, the pressure applied by the construction equipment to the wire 3 gradually decreases, so that the torque energy stored in the clockwork spring 53 is gradually released, so that the winding part of the clockwork spring 53 rotates counterclockwise with the rotating shaft 55 and gradually rotates back to the initial position;

[0061] In the process of the clockwork spring 53 gradually releasing the stored torque energy, the counterclockwise rotation of the rotating shaft 55 causes the winding rod 56 to rotate counterclockwise together, so that the pulled out stretching wire 57 is gradually wound around the outer surface of the winding rod 56, and the wire 3 is pulled back to the initial position by the tension of the stretching wire 57;

[0062] During the counterclockwise rotation of the winding rod 56, the driving linkage column 58, the synchronous wheel 1 59 and the bevel synchronous gear 510 rotate counterclockwise, and the counterclockwise rotation of the bevel synchronous gear 510 causes the bevel gear 511 and the driving gear 61 to rotate clockwise, so that the rack 62 drives the large slider 65 and the fixed plate 64 to move horizontally toward the side close to the retaining plate 63. At the same time, the slide plate 67, the large limit block 68, the guide column 69, the compression spring 1 610 and the compression spring 1 610 on the large slider 65 move horizontally together with the large slider 65 until the rack 62 drives the large slider 65 to move horizontally back to the initial position;

[0063] Compared with the prior art, the above steps prevent the wire 3 from moving back to its initial position by its own elastic force when the construction equipment is away from the wire 3. The present device uses the tension applied by the stretch wire 57 to the wire 3 to pull the wire 3 back to its initial position.

[0064] Embodiment 2:

[0065] Further, such as Figure 12 to Figure 14 As shown, the prompt component includes a limiting groove 71 opened in the hollow plate 42, and the limiting grooves 71 are provided with no less than two. The two limiting grooves 71 are slidably connected with arc plates 72. The arc plates 72 are located at one end of the limiting grooves 71 close to the slide plate 67, and the two arc plates 72 are fixedly connected with a push plate 73 on one side away from the limiting grooves 71. When the push plate 73 and the arc plates 72 move horizontally along the limiting grooves 71, the limiting grooves 71 can limit the moving path of the push plate 73 to prevent the push plate 73 from escaping from the interior of the hollow plate 42. The push plate 73 A compression spring 74 is fixedly connected inside, and the compression spring 74 is in a compressed state. One end of the compression spring 74 away from the push plate 73 is fixedly connected to a ball 75, which is used to limit the movement of the push plate 73. Ball pits 76 are opened inside the two hollow plates 42, and part of the ball 75 is located inside the ball pits 76. There are no less than four ball pits 76. A push rod 77 is fixedly connected to the outer wall of the push plate 73. An arrow 78 is fixedly connected to the upper surface of the protective cover 4. There are no less than two arrows 78, and the two arrows 78 are located above the push rod 77.

[0066] Further, such as Fig.14 As shown, the push plate 73 is slidably connected to the interior of the hollow plate 42, and the diameter of the ball 75 is matched with the aperture of the ball pit 76;

[0067] When working: the device can remind the inspector that the wire 3 has been stretched by collision and needs to be inspected. The detailed steps are as follows:

[0068] Referring to the first embodiment, when the slide plate 67 moves horizontally, the slide plate 67 enters the interior of the hollow plate 42 and hits the push plate 73, so that the push plate 73 moves horizontally along the limit groove 71 in the direction away from the side of the slide plate 67. In the process of the push plate 73 moving horizontally in the direction away from the side of the slide plate 67, the ball 75 moves in the direction close to the side of the push plate 73, thereby squeezing the second compression spring 74, so that the second compression spring 74 is further compressed, so that the ball 75 is pushed out of the ball pit 76;

[0069] When the ball 75 moves horizontally to the position of the next ball pit 76, the compression spring 2 74 extends to push the ball 75 into the inside of the next ball pit 76. At this time, the push plate 73 stops moving horizontally, and the push rod 77 on the push plate 73 is exposed from the inside of the hollow plate 42 and is located outside the hollow plate 42. The inspection personnel observe the direction of the arrow 78 on the surface of the protective cover 4 to observe the position of the push rod 77. When the push rod 77 is located outside the hollow plate 42, it reminds the inspection personnel that the wire 3 has been stretched by the collision of the construction equipment and needs to be inspected first. Compared with the prior art, there is no reminder device on the electric pole example 1. The inspection personnel may miss or misjudge the connection between the wire 3 and the insulator example 2 due to their own reasons. The present device uses the direction of the arrow 78 and the relative position of the push rod 77 on the hollow plate 42 to remind the inspection personnel of the objects to be inspected first, so as to avoid failure of the power line during subsequent use due to missed inspection.

[0070] When the inspector finds that the push rod 77 is located outside the hollow plate 42, the inspector can open the inspection door 41 above the protective cover 4 to check the wear of the connection between the wire 3 and the insulator example 2. When the wear is relatively minor, it means that no maintenance is required. The inspector closes the inspection door 41, pushes the push rod 77 located outside the hollow plate 42, and repeats the above steps in reverse, so that the push rod 77 drives the push plate 73 to move horizontally in the direction close to the side of the slide plate 67. During this process, the ball 75 is pushed out of the ball pit 76 where it is located and squeezes the compression spring 2 74. When the ball 75 moves horizontally to the initial position, the compression spring 2 74 extends to push the ball 75 into the ball pit 76 at the initial position. At this time, the push plate 73 returns to the initial position and remains stationary so that the next time the construction equipment collides with the wire 3 again, the next prompt will be given.

[0071] The above are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
