DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figures 1 to 7 In combination with the electric anti-external breakage warning device shown, it includes: a first mounting seat 2 and a second mounting seat 3 of a base plate 1 are provided at the bottom end, a first groove 4 is provided at the top of the first mounting seat 2, and a second groove 5 is provided at the bottom end of the second mounting seat 3. The first groove 4 and the second groove 5 are connected to form a wire passage, and a driving mechanism 7 for driving a bird repeller 6 to rotate is provided in the base plate 1, a PCB board 8 is provided in the base plate 1 outside one side of the driving mechanism 7, and a light source 9 at the bottom end of the PCB board 8 is opposite to a transparent part 10 at the bottom end of the base plate 1, and at least one speaker 11 for playing a warning voice is provided in the base plate 1 outside the other side of the driving mechanism 7.

[0025] Among them, after the first mounting seat 2 and the second mounting seat 3 located at the top of the first mounting seat 2 are fixed by bolts, the first groove 4 of the first mounting seat 2 and the second groove 5 of the second mounting seat 3 are opposite to and form a wire passing channel, and the wire passing channel is used to pass the wires to install the warning device at the corresponding position of the wires; the transparent part 10 is glass that can transmit light, and the light source 9 at the bottom of the PCB board 8 is opposite to the glass, which is conducive to the scattering of light generated by the light source 9 to the outside of the warning device, thereby warning the personnel who are taking soil near the warning device through light warnings to avoid contact between the equipment operated by the construction personnel and the wires during construction; and the light source 9 has the advantages of high brightness, low power consumption and high efficiency. When the light source 9 irradiates downward, a light cylinder is formed. The height of the light cylinder is consistent with the height of the wires. While being eye-catching, it can also achieve 270-degree all-round visibility.

[0026] In addition, two loudspeakers 11 for playing warning voices are symmetrically arranged in the base plate 1. The loudspeakers 11 have the advantages of low power consumption, low noise reduction and large dynamic range, and can play a warning sound greater than 90dB with a very small current, thereby utilizing the loudspeakers 11 to achieve voice warnings; through the combined use of light warnings and voice warnings, it is possible to better warn personnel who are taking soil near the warning device to avoid contact between the equipment operated by the construction personnel and the wires during construction, thereby ensuring safe construction while minimizing damage to the wires caused by construction.

[0027] In an optional embodiment, if Figure 4 , Figure 5 and Figure 6 As shown in the figure, it also includes: a plurality of CT power taking coils 12, a plurality of first matching grooves 13 symmetrically distributed on both sides of the first groove 4 are arranged at the top of the first mounting seat 2, a plurality of second matching grooves 14 symmetrically distributed on both sides of the second groove 5 are arranged at the bottom of the second mounting seat 3, and both ends of the CT power taking coil 12 are located in the first matching groove 13 and the second matching groove 14.

[0028] Among them, three CT power coils 12 are arranged in this embodiment, and the wires are inserted from one end of the wire passage, and then pass through the three CT power coils 12 in sequence, and then extend from the other end of the wire passage. The warning device obtains sufficient electric energy from the power line through the CT power coil 12, and provides it to the lighting circuit, the voice circuit and the speaker 11, so the warning device can be unaffected by the weather and fog, and the flashing warning and voice warning can still be realized during a short power outage; the installation process of one of the CT power coils 12 is taken as an example for explanation here, and the middle part of the CT power coil 12 is a ring structure, Fixed blocks are provided at both ends of the annular structure. During installation, the bottom of the annular structure is located in the first groove 4 at the top of the first mounting seat 2, and the bottoms of the fixed blocks at both ends are located in the first matching groove 13. Then the second mounting seat 3 is covered on the top of the first mounting seat 2 and fixed by bolts. At this time, the top of the annular structure is located in the second groove 5 of the second mounting seat 3, that is, the annular structure is located in the wire channel, and the tops of the fixed blocks at both ends are located in the second matching groove 14. At this point, the installation of one CT power taking coil 12 is completed. The installation process of the remaining CT power taking coils 12 is the same and will not be repeated here.

[0029] In addition, the signal generated by the CT power coil 12 is a smaller current proportional to the measured current. Through appropriate circuit design, this signal can be extracted and utilized to power the warning device. Specifically, a rectifier circuit is used to convert the AC signal output by the CT power coil 12 into a DC signal, and then a filter is used to smooth the signal. The output low voltage signal is then boosted to a level suitable for powering the warning device through a voltage adjustment circuit. A voltage stabilizer or switching power supply can also be used to ensure that power can be stably provided to the warning device, thereby ensuring the normal operation of the warning device.

[0030] In an optional embodiment, if Figure 3 As shown, the driving mechanism 7 includes: a motor 15 and a worm 16, the output end of the motor 15 is connected to the worm 16, and the worm 16 cooperates with a turbine 18 with a rotating shaft 17 in the middle. Both ends of the rotating shaft 17 pass through the wall of the first mounting seat 2 and are connected to the bird repeller 6.

[0031] Among them, the driving mechanism 7 drives the bird repeller 6 to rotate after receiving the control signal of the controller. Specifically, the motor 15 drives the worm 16 to rotate, and the worm 16 drives the rotating shaft 17 to rotate through the turbine 18, thereby realizing the rotation of the bird repeller 6 at both ends of the rotating shaft 17; using the driving mechanism 7 to drive the bird repeller 6 to drive away birds approaching the warning device can prevent the birds from damaging the warning device.

[0032] In an optional embodiment, if Figure 1 and Figure 3 As shown in the figure, the bird repeller 6 includes: a fixing ring 19 and a plurality of connecting rods 20 , wherein the plurality of connecting rods 20 are evenly arranged on the outer surface of the fixing ring 19 , and a sphere 21 is arranged at one end of the connecting rod 20 away from the fixing ring 19 .

[0033] Among them, in this embodiment, the bird repeller 6 is provided with three connecting rods 20, which are evenly distributed on the outer surface of the fixing ring 19. The connecting rods 20 are integrally formed with the fixing ring 19, and are directly connected to the rotating shaft 17 through the fixing ring 19 when fixed, thereby enabling the bird repeller 6 to be quickly assembled; the bird repeller 6 is mainly used to drive away birds to prevent birds from approaching the warning device, thereby preventing birds from damaging the warning device. In actual use, birds may stay or nest on the warning device, or even peck at the warning device and wires, causing damage to the warning device or functional failure. The warning device is provided with a bird repeller 6 to drive birds away from the warning device and reduce possible damage to the warning device caused by birds.

[0034] In an optional embodiment, if Figure 1 and Figure 2 As shown in the figure, the base plate 1 is connected to the first mounting seat 2 by bolts, and the first mounting seat 2 is also connected to the second mounting seat 3 located at the top of the first mounting seat 2 by bolts.

[0035] During assembly, four bolts are first used to fix the first mounting seat 2 and the base plate 1, and then four bolts are used to fix the first mounting seat 2 and the second mounting seat 3. The base plate 1, the first mounting seat 2 and the second mounting seat 3 are connected as a whole by bolts, so that a stable connection between the three can be achieved, preventing the warning device installed on the wire from falling from a height due to a loose connection, thereby ensuring the personal safety of people who may be in the area directly below the warning device.

[0036] In an optional embodiment, if Figure 2 and Figure 3 As shown in the figure, the outer wall of the bottom end of the bottom plate 1 facing the speaker 11 is provided with a shielding member 22 to prevent rainwater from entering the sound hole.

[0037] Among them, by arranging a shielding member 22 on the outer wall at the bottom end of the base plate 1, rainwater can be prevented from entering the sound hole of the speaker 11 without affecting the sound output, thereby protecting the electronic components and acoustic structure inside the speaker 11 from damage, ensuring that the quality and performance of the sound output are not disturbed, and also helping to extend the service life of the speaker 11 and reduce the maintenance cost of the warning device.

[0038] In an optional embodiment, if Figure 2 , Figure 4 and Figure 6 As shown in the figure, the cross sections of the first groove 4 and the second groove 5 are both arc-shaped.

[0039] The cross section of the electric wire is circular, so providing the first groove 4 and the second groove 5 in an arc shape is conducive to installing the warning device at the corresponding position of the electric wire.

[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
