Description

Technical Field

[0001] The present invention relates to the technical field of lightning arresters, in particular to a power supply component and a lightning arrester communication device. Background Art

[0002] A lightning arrester is an electrical device used to protect electrical equipment from high transient overvoltage hazards and limit the follow-on time and amplitude. An important challenge facing the intelligentization of lightning arresters is the stability and reliability of communication.

[0003] The power line carrier signal of the arrester communication device is coupled to the ground wire on the arrester through the coupler port. The arrester communication device receives the carrier signal and sends it to another device through the network port.

[0004] This process requires power supply, and the lightning arrester is usually installed on outdoor overhead lines. The equipment is powered by solar charging and discharging and external power supply.

[0005] When solar panels generate electricity, voltage and current fluctuations caused by changes in light intensity can lead to unstable output power of solar cells, causing frequent charging and discharging of the battery pack, which not only increases the number of battery cycles, but may also affect the service life and performance of the battery pack.

[0006] The lightning arrester communication device may be installed in a place with insufficient light, resulting in insufficient intensity of received sunlight. In addition, at night when there is no sunlight, street lamps on the roadside can be used as light sources, but the light intensity of such light sources is weak and the charging efficiency is low. Summary of the invention

[0007] The object of the present invention is to provide a power supply assembly and a lightning arrester communication device to solve the problems raised in the above-mentioned background technology.

[0010] A condensing screen is arranged at the opening of the condensing cylinder, a power assembly for driving a light receiving plate to approach or move away from the condensing screen along the main optical axis of the condensing screen is arranged in the condensing cylinder, and a light sensor is arranged on the light receiving plate at a position corresponding to the main optical axis of the condensing screen;

[0011] The circuit board controls the power component to adjust the moving position of the light receiving plate according to the signal input by the light sensor.

[0012] Preferably, the power assembly includes a driving motor and a lifting shaft installed on the side wall of the light receiving plate, and the driving motor is connected to the lifting shaft to drive the lifting shaft to move linearly.

[0016] Preferably, the condensing screen includes a glass medium and a first lens and a secondary lens arranged in the glass medium, the first lens is arranged at the center of the condensing screen, a plurality of groups of secondary lenses are evenly distributed around the first lens, and the outer diameter of the first lens is larger than that of the secondary lens.

[0017] Preferably, the secondary lens includes a second lens and a third lens having different outer diameters, and the second lens and the third lens are arranged alternately.

[0018] Preferably, the focusing tube is a cylindrical structure.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] After the light passes through the condensing screen, the light intensity change is detected by the light sensor, which enhances the light intensity in a specific direction or area.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment: A power supply component, such as Figure 1-2 As shown:

[0033] The invention comprises a cylindrical focusing tube 1, which is made of flame-retardant and high-temperature-resistant ABS material; the focusing tube 1 is hollow inside and has an opening on one side, and a focusing screen 4 is arranged at the opening, and both sides of the focusing screen 4 are convex lenses.

[0034] A sealing ring 5 is provided between the outer edge of the condensing screen 4 and the inner wall of the condensing tube 1 to improve the sealing performance.

[0035] A battery pack 2, a circuit board 3, a driving motor 10, a baffle 6, a light receiving plate 8, a lifting shaft 9, a sleeve 12 and a light sensor 13 are installed inside the focusing tube 1. The battery pack 2, the driving motor 10, the light receiving plate 8 and the light sensor 13 are all electrically connected to the circuit board 3.

[0036] The light receiving plate 8 is used to receive natural light and light from street lamps.

[0037] The optical sensor 13 is installed at the top center of the light receiving plate 8 (aligned with the center of the condensing screen 4). According to the light intensity, the optical sensor 13 outputs different photoelectric signals to the CPU of the circuit board 3. The optical sensor 13 is relatively located on the main optical axis path of the condensing screen 4.

[0038] The driving motor 10 can be an electric push rod or a sliding screw motor. The circuit board 3 outputs a pulse signal. The positive pulse drives the rotating shaft of the driving motor 10 to rise, and the negative pulse drives the rotating shaft of the driving motor 10 to fall.

[0039] The lifting shaft 9 is relatively installed on the rotating shaft of the driving motor 10 , and the lifting shaft 9 moves linearly relatively in the shaft sleeve 12 , and the moving direction of the lifting shaft 9 is consistent with the main optical axis direction of the condensing screen 4 .

[0040] The output interface board 81 is used to output the optical sensor 13 signal and the voltage and current signal to the circuit board 3 .

[0041] The circuit board 3 is used for automatic battery charging management, processing the photoelectric conversion signal output by the light sensor 13 , and outputting positive and negative pulse signals to the drive motor 10 .

[0042] An exhaust valve 7 is installed on the side wall of the focusing tube 1 to prevent the focusing screen 4 and the optical sensor 13 from generating fog when used outdoors, thereby affecting the sensitivity of the optical sensor 13.

[0043] The battery pack 2 is used for storing energy and for supplying power to various electrical components. The power output port 11 of the battery pack 2 is used for outputting voltage and current.

[0044] Working principle:

[0045] After receiving natural light waves or lights, they are focused to the light receiving plate 8 through the focusing screen 4. The light sensor 13 outputs a photoelectric signal to the CPU unit processor of the circuit board 3. When the light is very strong, the circuit board 3 outputs a positive pulse to control the shaft of the drive motor 10 to drive the light receiving plate 8 to rise, so that the focusing area increases and the charging current decreases;

[0046] When the light is weak, the circuit board 3 outputs a negative pulse to control the shaft of the driving motor 10 to drive the light receiving plate 8 downward, so that the focusing area is reduced and the charging current is increased;

[0047] When the light is weak, the light receiving plate 8 can automatically adjust the focusing focal length of the light receiving plate 8 to maintain a constant output current to charge the battery pack 2;

[0048] The CPU memory unit of the circuit board 3 has an initial value of photoelectric conversion when it leaves the factory. This initial value is the reference value when the light receiving board receives the strongest light signal.

[0049] like Figure 2 As shown, the condensing screen 4 includes a first lens 41 and a second lens 42 and a third lens 43 in a circular array with the first lens 41 as the center. The first lens 41 is relatively located at the center of the condensing screen 4, and the second lens 42 and the third lens 43 are arranged alternately. The outer diameter of the first lens 41 is larger, which is 2-4 times the outer diameter of the second lens 42, and the outer diameter of the second lens 42 is 1.5-3 times the outer diameter of the third lens 43. The periphery of the first lens 41, the second lens 42 and the third lens 43 is filled with a glass medium to form a lens with convex surfaces on both sides.

[0050] The first lens 41 is mainly used to gather large light beams, and the second lens 42 and the third lens 43 with two different outer diameters can gather light beams with smaller angles.

[0051] Furthermore, the main optical axis of each second lens 42 / third lens 43 of the annular array is tilted at a different angle relative to the main optical axis of the first lens 41, which is conducive to each second lens 42 / third lens 43 collecting smaller light in different directions. Therefore, when receiving light at a small angle, a second lens 42 / third lens 43 can focus the light approximately on the main optical axis of the first lens 41, which is convenient for the receiving plate 8 to receive.

[0052] A lightning arrester communication device, such as Figure 3 As shown:

[0053] It includes a box body 14 and a control panel arranged on the box body 14, a clamping and fixing device 15, a display screen 16, an external power supply port 17, a network port 18, a coupler port 19 and a power supply component.

[0054] The box 14 is installed on the electric pole through the clamping fixture 15, and the system parameters are set and the data communication display and alarm indication are performed through the display screen 16.

[0055] The battery pack 2 can also be connected to the mains through the external power supply port 17; the coupler port 19 is used to couple with the grounding wire of the lightning arrester, and the network port 18 is used to connect with external equipment; thus, when the lightning arrester fails, the control panel detects changes in the grounding wire of the lightning arrester and sends an alarm signal through the external device connected to the network port 18.
