[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Example 1

[0035] Reference Figure 1-4 , provides a high-voltage cable vibration energy collection device, comprising:

[0036] High voltage cable 100;

[0037] The mounting part 200 includes a ring sleeve 201 which is sleeved on the outside of the high-voltage cable 100 and a swing assembly 202 for fixing the ring sleeve 201 on the high-voltage cable 100;

[0038] The mechanical working part 300 is arranged between the high-voltage cable 100 and the installation part 200, and is used to generate an amplitude under the action of wind force by means of the high-voltage cable 100, so as to drive the mechanical working part 300 to impact and generate energy;

[0039] The conversion part 400 is installed at the bottom of the installation part 200 and is used to convert and store the energy generated by the mechanical work part 300.

[0040] Furthermore, the inner diameter of the ring sleeve 201 is greater than the diameter of the mechanical working part 300 , so as to dispose the mechanical working part 300 between the high-voltage cable 100 and the installation part 200 .

[0041] Specifically, the ring sleeve 201 is formed by merging two pipes with semicircular cross-sections. Fixing ears are symmetrically arranged on the outer sides of the two semicircular pipes. The fixing ears are fixed by bolts to complete the assembly of the two semicircular pipes, which has the effect of easy installation.

[0042] Furthermore, the swing assembly 202 includes two semicircular enclosure pieces 202a, the two enclosure pieces 202a are connected to the ring sleeve 201 through a swing rod 202b, and the two enclosure pieces 202a are enclosed on the outside of the high-voltage cable 100 and fastened by a tie clamp 202c.

[0043] Specifically, a rubber pad is attached to the inner side of the enclosing piece 202a. The rubber pad is soft and has a high friction coefficient. It has a stabilizing effect when clamping the high-voltage cable 100 and will not cause external damage to the high-voltage cable 100.

[0044] Furthermore, the swing rod 202b is made of stainless steel, one end of which is fixed to the outside of the ring sleeve 201, and the other end is fixed to the outside of the enclosure sheet 202a, and the middle section of the swing rod 202b is a sheet structure with a width of 1.8mm and a thickness of 3mm. This design allows the swing rod 202b to have the ability to carry objects while also having lateral swinging properties. One end of the swing rod 202b is fixedly installed on the high-voltage cable 100 through the enclosure sheet 202a. The high-voltage cable 100 will produce a small amount of horizontal vibration when affected by wind at high altitude. At this time, the end of the pendulum rod 202b connected to the high-voltage cable 100 will swing accordingly, but the sheet design of the middle section of the pendulum rod 202b makes it impossible for the horizontal swinging force to directly act on the ring sleeve 201. Because the weight of the ring sleeve 201 and the conversion part 400 is heavy, the swinging force will produce elastic deformation when passing through the middle section of the pendulum rod 202b under the influence of the gravity of the ring sleeve 201, and the swing amplitude is small. Therefore, the middle section of the amplitude rod 202b will continue to reciprocate horizontal elastic motion, which will cause the ring sleeve 201 to be in a relatively static state.

[0045] Furthermore, the mechanical working part 300 includes a piezoelectric component 301 arranged inside the ring sleeve 201 and an impact component 302 installed on the high-voltage cable 100. When the high-voltage cable 100 is swung by wind, the impact component 302 is driven to impact the piezoelectric component 301 and generate energy.

[0046] Furthermore, the piezoelectric component 301 uses a plurality of arc-shaped piezoelectric ceramic sheets, the plurality of piezoelectric ceramic sheets are adhered to the inner side of the ring sleeve 201, and the plurality of piezoelectric ceramic sheets are connected in series through wires.

[0047] The conversion part 400 is fixedly installed on the bottom of the ring sleeve 201 through a steel wiring tube. The steel wiring tube is used to fix the conversion part 400 on the one hand, and to route the conversion part 400 on the other hand, so as to form a passage between the piezoelectric component 301.

[0048] The sleeve 302a is made of ceramic material and has an insulating effect. Both ends of the sleeve 302a are equipped with tensioners for firmly installing the sleeve 302a on the outside of the high-voltage cable 100.

[0049] Specifically, the tensioner is a bolt, the outer surface of which is coated with an insulating coating, and the bolt passes through the sleeve 302a and is threadedly connected thereto. By rotating the bolt, the bolt moves horizontally along the thread direction against the outer side of the high-voltage cable 100, thereby completing the fixing of the sleeve 302a and avoiding displacement during the oscillation process.

[0050] Furthermore, the impact assembly 302 includes a sleeve 302a, and a plurality of impact balls 302b are mounted on the surface of the sleeve 302a.

[0051] Specifically, the sleeve 302a oscillates with the high-voltage cable 100. Since the ring 201 does not oscillate, the impact ball 302b on the outside of the sleeve 302a will continuously hit the piezoelectric component 301 on the inside of the ring 201 when the sleeve 302a oscillates. The piezoelectric component 301 will generate current when hit by external force.

[0052] Specifically, the conversion part 400 includes a control box, in which a transformer module, a controller module and a power storage module are arranged, and an output module is arranged on the outer wall of the control box, and the transformer module, the controller module and the output module are all electrically connected to the power storage module;

[0053] The transformer module is used to convert the voltage transmitted by the wiring harness. The controller module is used to control the transformer module, the power storage module and the output module. The power storage module is used to store the converted electric energy and power the subsequent sensors. The output module can also be directly connected to the sensor to directly power the sensor.

[0054] The control box is filled with insulating gas, including but not limited to SF6 gas and nitrogen. The insulating gas can ensure the safety of the transformer module, power storage module and output module in the control box and avoid being affected by high-voltage cables.

[0055] The structure utilizes the swing of the high-voltage cable 100 in the wind to drive the impact ball 302b to hit the piezoelectric component 301 to generate energy, which is then converted into electrical energy storage by the conversion part 400 to provide energy supply for the monitoring equipment that monitors the high-voltage cable, and realize the long-term guarantee of the power consumption of the monitoring equipment. There is no need to manually replace the battery, which solves the problem of difficulty in replacing the battery of the high-voltage line.

[0056] Generating electricity by collecting the swing force of high-voltage cables is more effective than solar power generation. There are no obstacles in the sky, and the air pressure gradient is greater, which leads to increased wind speed. Therefore, there is no need to worry about power shortages. Solar power generation is greatly affected by weather, and the large size of photovoltaic panels makes installation inconvenient.

[0057] Example 2

[0058] Reference Figure 5This embodiment is different from the first embodiment in that an annular heat dissipation cavity 302c is provided inside the sleeve 302a, and a plurality of heat dissipation holes 1 302d are equidistantly provided on the inner side of the sleeve 302a, and a plurality of heat dissipation holes 2 302e are equidistantly provided on the outer side of the sleeve 302a, and the heat dissipation cavity 302c, the heat dissipation holes 1 302d and the heat dissipation holes 2 302e are connected to form a heat dissipation channel.

[0059] The sleeve 302a is wrapped around the outside of the high-voltage cable 100, which will cause the heat in this section of the high-voltage cable 100 to dissipate slowly, which may easily lead to safety hazards. Through the design of the heat dissipation cavity 302c, the heat dissipation hole 1 302d and the heat dissipation hole 2 302e, the heat can be discharged from the heat dissipation channel to form air circulation.

[0060] The rest of the structure is the same as that of Example 1.

[0061] Example 3

[0062] Reference Figure 6 This embodiment is different from the above embodiments in that the mechanical working part 300 also includes a cooling component, and the cooling component adopts multiple groups. The multiple groups of cooling components are equidistantly installed on the surface of the sleeve 302a to quickly reduce the heat accumulated in the heat dissipation cavity 302c.

[0063] Specifically, the cooling component includes a heat sink 301f, and a heat sink fin 301g is embedded on the outside of the heat sink 301f. The heat sink 301f is a hollow structure with a cooling medium inside. One end of the heat sink 301f passes through the sleeve 203a and extends into the heat dissipation cavity 302c. A heat exchange fin is provided at the end of the heat sink 301f in the heat dissipation cavity 302c. When the temperature inside the heat dissipation cavity 302c is too high, the heat exchange fin will absorb heat and transfer it to the heat sink 301f. After the heat sink 301f absorbs heat, the cooling medium inside it evaporates and rises, and the steam is adsorbed on the heat sink fin 301g. The heat sink fin 301g has an outer portion that passes through the inner side of the heat sink 301f. The external heat sink fin 301g will be cooled by air circulation. After cooling, the steam adsorbed on the heat sink fin 301g inside the heat sink 301f will condense into liquid and be reused.

[0064] This structure allows the heat generated by long-term impact to be released, and also prevents the high-voltage cable 100 from overheating and causing safety hazards.

[0065] The rest of the structure is the same as that of Example 2.
