Description

[0002] ‌Photovoltaic cables refer to the cables used for power transmission in the DC side circuit of a solar photovoltaic power station system, and have excellent physical properties such as resistance to high and low temperatures, ultraviolet radiation, water, salt spray, weak acids and alkalis, aging resistance, and flame retardancy.

[0003] However, for the cables laid underground, especially in humid and hot regions such as Southeast Asia and the southern part of China, accidents of termite erosion of the cable plastic sheath occur frequently. Termites not only bite the cables, but also secrete formic acid, which seriously corrodes the insulation and sheath of the cables, resulting in a decline in insulation performance and even short circuits. The damage of rats to underground cables is mainly caused by mechanical damage through biting. Therefore, most underground cables are provided with rodenticides and termiticides, and the appearance and operating status of the cables are regularly inspected. However, both rodenticides and termiticides have a shelf life and lose their effectiveness after being used for a period of time, so the protection effect is lost.

[0035] Reference Figure 5 As shown, the connecting mechanism 5 includes two arc-shaped plates 51, one side of the arc-shaped plates 51 is connected with a clamping end 52, one side of the clamping end 52 is connected with a main limiting cone head 53, one side of the arc-shaped plates 51 is connected with a secondary limiting cone head 54, and the arc-shaped plates 51 are provided with a through hole 55. The two arc-shaped plates 51 can be assembled into a circle after docking and installation. Because the arc-shaped plates 51 are fixedly connected to the outer protective layer 7, the connecting mechanism 5 is pre-assembled after the outer protective layer 7 is spliced. Then, the main limiting cone head 53 is inserted into the connecting hole 14 on one side of the connecting frame 12 and the side frame 13, so as to be connected to the connecting frame 4. It can be seen from the accompanying drawings that the main limiting cone head 53 is provided with an elastic cone head at one end, and at the same time, through the attached Figure 7 It can be seen that small holes are provided on one side of the left chamber 41 and the right chamber 42 corresponding to the secondary limiting cone head 54, which can further ensure the stability of the connection.

[0036] Reference Figure 4As shown, the outer protective layer 7 includes a right sandwich layer 71 and a left sandwich layer 72. Clamping heads 73 are connected and arranged on both sides of the left sandwich layer 72. Limiting holes are correspondingly opened on both sides of the right sandwich layer 71 for the clamping heads 73. The inner protective layer 8 has the same structure as the outer protective layer 7. The right sandwich layer 71 and the left sandwich layer 72 are also arranged in an arc shape and form a cylindrical shape when spliced and combined. The shielding layer 9 is also arranged in an arc shape and adheres to the inner walls of the right sandwich layer 71 and the left sandwich layer 72. It is clamped into the limiting holes through the clamping heads 73 to complete the splicing of the outer protective layer 7. The inner protective layer 8 is installed in the same way to hold tightly on the surface of the cable. Thus, a relatively complete shielding area is formed by the shielding layer 9 to avoid the influence of sound waves and electronic pulses on the use of the cable. At the same time, it can also achieve a guiding effect on sound waves and electronic pulses. The lengths of the outer protective layer 7, the inner protective layer 8, and the shielding layer 9 can be set according to needs. The number of internal support frames 10 can also be increased according to needs. The internal support frame 10 is made of arc-shaped quartz material, greatly reducing the influence on the propagation of sound waves and electronic pulses.

The cable core wire 101 in the cable is inserted into the terminal head 63, and then a tool, such as a tool clamp, is used to rotate and fold the wire holding end 62 to clamp the cable core wire 101 to complete the connection with the cable. Among them, in the wire groove 64, the wire connected to the power connection unit 15 can be clamped into the wire groove 64, playing a role of limiting and protection.

[0038] Referring to Figure 8 As shown, the integrated electronic pulse generating mechanism includes a ne555 pulse generator 27 fixedly arranged on one side of the first aluminum shell 16 and a bottom plate 28 connected and arranged on one side of the inner wall of the first aluminum shell 16.

A second circuit board 29 is connected and arranged on one side of the bottom plate 28. A storage capacitor 310, a clock source 301, an attenuator 302, and a discharge resistor 303 are connected and arranged on one side of the second circuit board 29.

One side of the second circuit board 29 is connected to the protection unit through a wire.

[0039] Referring to Figure 8As shown, the protection unit includes a third circuit board 341. On one side of the third circuit board 341, an output buffer 342, an overvoltage protection 343, an overcurrent protector 344, and an electrostatic protector 345 are connected and arranged. The overvoltage protection 343 prevents the pulse generator from being damaged due to excessive power supply voltage. The overcurrent protector 344 prevents the pulse generator or the load from being damaged due to excessive output current. The electrostatic protector 345 prevents sensitive electronic components from being damaged by electrostatic discharge. The output buffer 342 protects the output stage of the pulse generator, ensures stable signal output, and at the same time isolates the influence of the load on the generator, playing a protective role for the integrated electronic pulse generating mechanism.

[0040] Refer to Figure 9 As shown, the integrated acoustic wave generating mechanism includes a micro acoustic wave generator 18 and a fixing frame 19 connected and arranged on one side of the inner wall of the second aluminum shell 17. On one side of the fixing frame 19, a first circuit board 20 is connected and arranged.

On one side of the inner wall of the second aluminum shell 17, an auxiliary frame 23 is connected and arranged. On one side of the auxiliary frame 23, an EC21 ultra-thin encoder 24, a microcontroller 25, and a protection resistor 26 are connected and arranged. The microcontroller 25 is used to control the start, stop, frequency adjustment, mode switching, etc. of the acoustic wave emitter. The EC21 ultra-thin encoder 2 plays a role in positioning the micro acoustic wave generator 18 at the corresponding position for easy maintenance. The protection resistor 26 plays a protective effect.

[0041] Refer to Figure 7 As shown, the power-on unit 15 includes a resistor 151. Wire connectors 152 are connected and arranged on both sides of the resistor 151. Terminal jacks 153 are connected and arranged on one side of the wire connectors 152. Among them, the resistor 151 is electrically connected to the corresponding integrated acoustic wave generating mechanism and integrated electronic pulse generating mechanism. During use, a wire with a terminal can be inserted into the terminal jack 153 to make it energized with the wire connector 152, and then power is supplied to the corresponding mechanism through the resistor 151. The insertion is convenient, so that each mechanism on the cable forms a series connection.

[0042] The implementation principle of this application is as follows: When this invention is in use, the cable is connected to the power distribution cabinet or directly to the transformer through the connection terminal 6. There is an independent external power source in the power distribution cabinet or the direct transformer. The external power source and the power supply connection unit 15 located at the end of this cable are connected by wires, so as to supply power to all the integrated acoustic wave generating mechanisms and integrated electronic pulse generating mechanisms on the cable. When buried underground, the integrated acoustic wave generating mechanism can regularly emit acoustic waves. On the one hand, it can drive away ants and rats. On the other hand, after the acoustic wave sensor 171 receives the reflected acoustic wave signal, it can observe the surface of the cable to ensure that any damage other than being damaged by ants and rats is detected in time. By sending acoustic waves and receiving their reflected waves, it can be judged whether there is a large rodent approaching near the cable. When detected, the electronic pulse generating mechanism sends an electronic pulse to drive away the large rodent and protect the cable. The settings of the external heat shrinkable layer 11, the outer protective layer 7, the inner protective layer 8, and the internal shielding layer 9 can greatly improve the anti-aging effect of the cable body 1.
