Description

Technical Field

[0001] The present invention relates to the technical field of power lines, and more particularly, to an external damage protection device for power lines. Background Art

[0002] External damage to power lines refers to the damage to transmission lines caused by human, construction and other factors in the line corridor and protection area. External force damage to transmission lines will lead to faults such as open circuits and short circuits, resulting in power supply interruption and affecting the normal power consumption of users. Existing technical methods usually strengthen the awareness of power protection by hanging warning signs and publicizing power laws and regulations, or installing on-line monitoring devices for preventing external damage to capture videos. However, the existing cameras have their imaging functions blocked due to long-term lack of maintenance, and cannot effectively monitor. Moreover, the existing camera monitoring is only simple monitoring and cannot protect the lines when external force is applied by construction equipment, and the power lines are often damaged.

[0003] To solve the above problems, the inventor has proposed an external damage protection device for power lines. Summary of the Invention

[0008] Preferably, one end of each of the two clockwork springs is located at the bottom of the limiting block. One end of each of the two clockwork springs close to the middle of the disc is inserted into the limiting groove. The limiting column is located on the outer wall of the clockwork spring.

[0009] Preferably, one end of each of the two stretching wires is fixedly connected to the outer surface of the winding rod. The ends of the two stretching wires away from the winding rod are slidably connected to the electric wire. The two first synchronous pulleys are rotatably connected to the pole example through support columns. The umbrella-shaped synchronous gear is rotatably connected to the pole example through a support column. The umbrella-shaped gear is rotatably connected to the pole example.

[0010] Preferably, the alarm component includes a driving gear rotatably connected to the umbrella-shaped gear. There are at least two such driving gears. The outer sides of the two driving gears are meshed with a rack. A retaining plate is fixedly connected to the inner side wall of the pole example. On the retaining plate, fixing plates are symmetrically and fixedly connected. There are at least two fixing plates.

An electrode piece is fixedly connected to the outer wall of the sliding plate. A large limiting block is fixedly connected to the upper surface of the sliding plate. A guiding column is fixedly connected to the outer wall of the sliding plate. A first compression spring is sleeved on the outer side of the guiding column.

[0015] Preferably, the push plate is slidably connected to the hollow plate, and the round ball is matched with the ball pit.

[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] Through the prompting component, the pushing plate can be automatically ejected after the wire is collided, so that the push rod moves from the inside of the hollow plate to the outside of the hollow plate. With the guiding function of the arrow, it helps the inspection personnel quickly identify the wires that need to be inspected key points, reminds the inspection personnel that the wires have been collided, prompts them to conduct a detailed inspection of the wire conditions, and improves the inspection efficiency. Compared with the traditional inspection method, the prompting component provides a more explicit inspection indication, reduces the judgment and omission of the inspection personnel, and improves the pertinence and efficiency of the inspection. Compared with relying on the subjective judgment of the inspection personnel, the relative position of the push rod provides an objective and explicit inspection indication, reducing the possibility of human missed inspections;

[0020] The protective cover is installed above the insulator example, thereby covering 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 in which the insulator example is directly exposed to the environment, this method can reduce the accumulation of pollutants, prevent the insulation performance from decreasing due to dirt accumulation on the surface of the insulator example, slow down the corrosion process, improve the service life of the insulator example, and reduce the risk of electrical failures.

[0044] As Figures 2 to 8 shown, the stretching component includes discs 51 fixedly connected to the inside of the protective cover 4. There are no less than two discs 51.

The limiting grooves 5501 are adapted to the clockwork spring 53, and the end at the center of the clockwork spring 53 is inserted into the limiting groove 5501. The ends of the two rotating shafts 55 away from the discs 51 are fixedly connected with winding rods 56. A stretching wire 57 is wound around the outer surface of the winding rod 56. The stretching wires 57 respectively exert a pulling force on the wire 3, so as to maintain the position and stability of the wire 3. The end of the winding rod 56 away from the rotating shaft 55 is fixedly connected with a linkage column 58. The end of the linkage column 58 away from the winding rod 56 is fixedly connected with a first synchronous wheel 59. The first synchronous wheel 59 is connected to an umbrella-shaped synchronous gear 510 through a synchronous belt. The outside of the umbrella-shaped synchronous gear 510 is meshed with an umbrella-shaped gear 511;

[0045] Further, as Figure 6 and Figure 7 shown, one end of the two clockwork springs 53 is located at the bottom of the limiting block 52, and the limiting post 54 is located on the outer wall of the clockwork spring 53;

[0046] Further, as Figure 4 , Figure 5 and Figure 8As shown in the figure, one end of each of the two stretching wires 57 is fixedly connected to the outer surface of the wire winding rod 56, and the other ends of the two stretching wires 57 away from the wire winding rod 56 are slidably connected to the electric wire 3. The first synchronous pulley 59 is rotatably connected to the electric pole example 1 through a support column, the umbrella-shaped synchronous gear 510 is rotatably connected to the electric pole example 1 through a support column, and the umbrella-shaped gear 511 is rotatably connected to the electric pole example 1;

[0047] Further, as Figures 8 to 13 shown in the figure, the alarm component includes a driving gear 61 rotatably connected to the umbrella-shaped gear 511. There are at least two driving gears 61. A rack 62 is meshed and connected to the outer sides of the two driving gears 61. A retaining plate 63 is fixedly connected to the inner side wall of the electric pole example 1. Fixing plates 64 are symmetrically and fixedly connected to the retaining plate 63. There are at least two fixing plates 64. A large slider 65 is slidably connected to the upper surfaces of the two fixing plates 64. A chute 66 is formed on the surface of the large slider 65. A sliding plate 67 is slidably connected in the chute 66. An electrode plate 6701 is fixedly connected to the outer wall of the sliding plate 67. A large limiting block 68 is fixedly connected to the upper surface of the sliding plate 67. A guiding column 69 is fixedly connected to the outer wall of the sliding plate 67. A first compression spring 610 is sleeved on the outer side of the guiding column 69. A blocking plate 611 is fixedly connected to the upper surface of the large slider 65. Support plates 612 are fixedly connected to the outer walls of the two fixing plates 64. A rotating rod 613 is rotatably connected to the side of the support plate 612 close to the fixing plate 64. A blocking block 614 is fixedly connected to the bottom of the rotating rod 613. Electric contact points 615 are fixedly connected to the interiors of the two hollow plates 42. A buzzer 616 is fixedly connected to the upper surface of the protective cover 4;

[0048] Further, as Figure 9 and Figure 11 shown in the figure, the two driving gears 61 are rotatably connected to the fixing plate 64, and the rack 62 is fixedly connected to the outer wall of the large slider 65;

[0049] Further, as Figure 9 and Figure 11 shown in the figure, the sliding plate 67 is located at one end of the chute 66 away from the blocking plate 611. The large limiting block 68 is composed of a triangular limiting block and a trapezoidal limiting block. One end of the first compression spring 610 away from the sliding plate 67 is fixedly connected to the blocking plate 611. The guiding column 69 is slidably connected to the blocking plate 611. A clamping block is fixedly connected to the outer surface of the guiding column 69. The clamping block is square and is in contact with the blocking plate 611, which is used to limit the displacement of the guiding column 69.

[0050] Further, as Figure 13 shown in the figure, the sliding plate 67 is slidably connected to the hollow plate 42, and the sliding plate 67 can horizontally move into the interior of the hollow plate 42;

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

[0052] When the construction instrument collides with the wire 3 and squeezes it, causing the wire 3 to deform significantly with the contact point as the center, at this time, the tension of the wire 3 increases, and the tensile wire 57 in the direction opposite to the direction in which the wire 3 is pushed and deformed is synchronously pulled out following the wire 3, causing the winding rod 56 to rotate clockwise. The rotation of the winding rod 56 drives the rotation of the rotating shaft 55. 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 first synchronous wheel 59 to rotate clockwise. The first synchronous wheel 59 causes the umbrella-shaped synchronous gear 510 to rotate clockwise together with the first synchronous wheel 59 through the synchronous belt. The clockwise rotation of the umbrella-shaped synchronous gear 510 causes the engaged umbrella-shaped gear 511 to rotate counterclockwise, and the counterclockwise rotation of the umbrella-shaped gear 511 causes the driving gear 61 to also rotate counterclockwise;

[0054] When the driving gear 61 rotates counterclockwise, the rack 62 engaged with the driving gear 61 drives the large slider 65 to move horizontally along the fixed plate 64 in the direction away from the retaining plate 63. At the same time, the sliding plate 67, the large limit block 68, the guide post 69, the first compression spring 610 and the blocking plate 611 above the large slider 65 move horizontally together with the large slider 65. During the process of the large slider 65 moving horizontally in the direction away from the retaining plate 63, the vertical surface of the large limit block 68 will gradually contact the inclined surface of the rotating rod 613. When the inclined surface of the rotating rod 613 contacts the triangular limit block in the large limit block 68, the triangular limit block of the large limit block 68 will squeeze the rotating rod 613, causing the rotating rod 613 to rotate with the rotation connection with the support plate 612 as the axis until the large limit 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 limit block 68 and the vertical surface of the extrusion blocking block 614 are in opposite faces, the rotating rod 613 stops rotating, the blocking block 614 blocks the large limit 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 sliding plate 67 at the bottom of the large limit block 68 stay in place, while the large slider 65 and the first compression spring 610 above the large slider 65 continue to move horizontally. During this process, the large slider 65 drives the blocking plate 611 to continue moving, so the distance between the sliding plate 67 and the blocking plate 611 gradually decreases, the guide post 69 moves horizontally along the blocking plate 611, and the first compression spring 610 between the sliding 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 come into contact with the inclined surface of the baffle 611. When the inclined surface of the rotating rod 613 contacts the inclined surface of the baffle 611, the baffle 611 pushes up the rotating rod 613, causing the rotating rod 613 to rotate counterclockwise with the rotation connection point with the support plate 612 as the axis. When the baffle 611 pushes up the rotating rod 613, the large limit block 68 loses the block of the blocking block 614. At this time, the energy storage of the first compression spring 610 reaches the maximum. As the blocking of the large limit block 68 by the blocking block 614 disappears, the first compression spring 610 will stretch, exert a thrust on the sliding plate 67, and horizontally move the large limit block 68 and the sliding plate 67 quickly in the direction away from the baffle 611;

[0057] When the sliding plate 67 moves horizontally quickly, it will enter the interior of the hollow plate 42. At this time, the electrode piece 6701 on the outer wall of the sliding 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, reminding the operator of the construction equipment that the construction equipment has collided with the wire 3 and exerted pressure on the wire 3. Please immediately operate the construction equipment away from the wire 3. Compared with the existing method of setting up warning signs or installing cameras for monitoring, the camera's imaging function is blocked due to long-term lack of maintenance and cannot effectively monitor. Through the continuous alarm sound emitted by the buzzer 616, the operator is reminded to operate the construction equipment to immediately leave the wire 3, thereby protecting the wire 3 in a timely manner;

[0058] When many birds stand on the surface of the wire 3, the wire 3 will undergo obvious deformation. At this time, the wire 3 pulls the tension wire 57, and the linkage column 58 rotates clockwise, driving the rack 62 to move until the blocking block 614 contacts the inclined surface of the baffle 611. Then, repeat the above steps to trigger the buzzer 616 to emit a continuous alarm sound, effectively driving away the birds. Compared with the problem of installing cameras in the prior art and being unable to drive away the birds, through the alarm emitted by the buzzer 616, the birds standing on the surface of the wire 3 are effectively driven away, avoiding the wire 3 from being damaged due to excessive pressure;

[0059] When the construction equipment is moved out of 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, reverse the above steps. Since the construction equipment is gradually moving away from the wire 3, the pressure exerted by the construction equipment on the wire 3 gradually decreases, causing the torque energy stored in the hairspring 53 to be gradually released, causing the wound part of the hairspring 53 to rotate counterclockwise with the rotating shaft 55 and gradually rotate 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 Figures 12 to 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 Figure 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] During operation: The device can prompt the inspection personnel that the wire 3 has been collided and stretched, and key inspection is required. The detailed steps are as follows:

[0068] Referring to Embodiment 1, when the sliding plate 67 moves horizontally, the sliding plate 67 will enter the interior of the hollow plate 42 and impact the pushing plate 73, causing the pushing plate 73 to move horizontally along the limiting groove 71 in the direction away from the sliding plate 67. During the process of the pushing plate 73 moving horizontally in the direction away from the sliding plate 67, the spherical ball 75 moves in the direction towards the pushing plate 73, thereby squeezing the second compression spring 74, causing the second compression spring 74 to be further compressed, and thus the spherical ball 75 is pushed out of the interior of the corresponding ball pit 76.

[0069] When the spherical ball 75 moves horizontally to the position where the next ball pit 76 is located, the second compression spring 74 elongates and pushes the spherical ball 75 into the interior of the position where the next ball pit 76 is located. At this time, the pushing plate 73 stops moving horizontally, and the push rod 77 on the pushing plate 73 is exposed from the interior of the hollow plate 42 and is located outside the hollow plate 42. The inspection personnel can observe the position of the push rod 77 by observing the direction of the arrow 78 on the surface of the protective cover 4. When the push rod 77 is located outside the hollow plate 42, it prompts the inspection personnel that the wire 3 has been collided and stretched by construction equipment and needs to be prioritized for key inspection. Compared with the prior art where there is no reminder device on the electric pole example 1, the inspection personnel may miss or misjudge due to their own reasons and thus fail to inspect the connection between the wire 3 and the insulator example 2. This device uses the direction of the arrow 78 and the relative position of the push rod 77 with respect to the hollow plate 42 to prompt the inspection personnel of the object to be inspected first, avoiding potential failures in the subsequent use of the power line due to missed inspections.

[0070] When the inspection personnel find that the push rod 77 is located outside the hollow plate 42, the inspection personnel can open the inspection door 41 above the protective cover 4 to check the wear condition of the connection between the wire 3 and the insulator example 2. When the wear condition is relatively minor, it means that no repair is required. The inspection personnel close the inspection door 41 and push the push rod 77 located outside the hollow plate 42, repeating the above steps in reverse, causing the push rod 77 to drive the pushing plate 73 to move horizontally in the direction towards the sliding plate 67. During this process, the spherical ball 75 is pushed out of the interior of the corresponding ball pit 76 and squeezes the second compression spring 74. When the spherical ball 75 moves horizontally to the initial position, the second compression spring 74 elongates and pushes the spherical ball 75 into the ball pit 76 at the initial position. At this time, the pushing plate 73 returns to the initial position and remains stationary, so as to make the next prompt when the construction equipment collides with the wire 3 again.

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