Description

Technical Field

[0001] The present invention belongs to the technical field of high-voltage detection, and particularly relates to a voltage display device adapted to a high-voltage electroscope. Background Art

[0002] A high-voltage electroscope is a tool for detecting whether high-voltage overhead lines, cable lines, and high-voltage electrical equipment are energized. Traditional high-voltage electroscopes generally consist of an insulating handle, a telescopic rod body, and an indicator. Both the insulating handle and the telescopic rod body are made of insulating materials. To ensure the safety of the power measurement work, there needs to be a certain safety distance between the indicator and the handheld part. The higher the voltage, the longer this safety distance should be.

[0003] Currently, high-voltage electroscopes with voltage display functions on the market, in addition to the insulating handle and the telescopic rod body, also have a collector and a receiver. The collector and the receiver are generally connected wirelessly. The disadvantage of this device is that a battery needs to be installed in the receiver for operation. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides a voltage display device adapted to a high-voltage electroscope. The voltage detector transmits the voltage through an optical signal to the voltage display, so that the voltage display directly displays the voltage value when receiving the optical signal.

[0005] To achieve the above object, the present invention provides the following technical solution: A voltage display device adapted to a high-voltage electroscope includes a voltage display installed at the insulating handle and a voltage detector installed at the detection end of the telescopic rod body. The voltage detector is electrically connected to the collector. The voltage detector is used to detect the voltage and convert the electrical signal into an optical signal and transmit it to the voltage display, and the voltage display displays the voltage after receiving the optical signal.

[0006] Preferably, as a voltage display device adapted to a high-voltage electroscope of the present invention, the voltage detector includes a detector bracket, a plurality of multicolor laser lights capable of emitting different colors of laser, and a detection control box. The plurality of multicolor laser lights are fixedly connected to the detection end of the telescopic rod body through the detector bracket. One end of the detector bracket is fixedly connected to the detection control box, and the detection control box is electrically connected to the collector. The detection control box is used to convert the voltage value into an electrical signal to control the operation of the multicolor laser lights.

[0007] Preferably, as a voltage display device adapted to a high-voltage electroscope of the present invention, the voltage display includes a structure in the shape of a Chinese character 'Ri' composed of seven display bars. There are several groups of the 'Ri'-shaped structures. The display bars are optically connected to a light-receiving energy-gathering cover, and several display bars optically connected to one light-receiving energy-gathering cover respectively receive lasers of different colors.

[0008] Preferably, in the "day" - shaped structures of different groups, the correspondingly - positioned display bars are respectively and sequentially optically - conductively connected to a light - receiving energy - concentrating cover through an optical - conduction channel, an optical - conduction adapter cone, and a monochromatic light conductor.

[0009] Preferably, in a voltage display device adapted to a high - voltage electroscope according to the present invention, the number of optical - conduction adapter cones and monochromatic light conductors optically - conductively connected to a light - receiving energy - concentrating cover corresponds to the number of "day" - shaped structures.

[0010] Preferably, in the same group of "day" - shaped structures of the present invention, each display bar is respectively and sequentially optically - conductively connected to a light - receiving energy - concentrating cover through an optical - conduction channel and a monochromatic light conductor.

[0011] Preferably, there are seven light - receiving energy - concentrating covers in a voltage display device adapted to a high - voltage electroscope according to the present invention.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The voltage display is arranged at the insulating handle, which is convenient for the user to observe the voltage value. The voltage detector transmits the voltage information to the voltage display through an optical signal, so that the voltage display directly displays the voltage value when receiving the optical signal. This not only avoids the disadvantage that the voltage display needs to be separately powered, but also the voltage display and the voltage detector still adopt a wireless connection method, thus avoiding the risk of electric shock and having a certain degree of safety.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1-5 shown:

[0027] A voltage display device adapted to a high-voltage electroscope includes a voltage display 4 installed at the insulating handle 1 and a voltage detector 5 installed at the detection end of the telescopic rod body 2. The voltage detector 5 is electrically connected to the collector 3. The voltage detector 5 is used to detect the voltage and convert the electrical signal into an optical signal and transmit it to the voltage display 4. The voltage display 4 displays the voltage after receiving the optical signal.

[0028] In this solution, in order to ensure safety during the electricity measurement work, a wired connection cannot be used between the voltage detection and the voltage display 4, which is prone to electric shock danger. And when transmitting signals by radio, the voltage display 4 needs to be powered separately, which will not only increase the weight of the device, but also requires timely charging. Forgetting to charge will cause the voltage display 4 to not work. Therefore, in this solution, the voltage display 4 is set to display the voltage without power supply. The voltage display 4 is set at the insulating handle 1, which is convenient for the user to observe the voltage display value. If the voltage display part is set on the voltage detector 5, since during work, the voltage detector 5 is generally at a certain distance from the user, it is difficult to see the value clearly. The voltage detector 5 transmits the optical signal to the voltage display 4, so that the voltage display 4 directly displays the voltage value after receiving the optical signal. This not only avoids the disadvantage that the voltage display 4 needs to be powered separately, but also the voltage display 4 and the voltage detector 5 still use a wireless connection method, and there will be no electric shock danger, having a certain safety.

[0029] In an alternative embodiment, the voltage detector 5 includes a detector support 51, a plurality of multicolor laser lamps 52 capable of emitting lasers of different colors, and a detection control box 53. The plurality of multicolor laser lamps 52 are fixedly connected to the detection end of the telescopic rod body 2 through the detector support 51. One end of the detector support 51 is fixedly connected with a detection control box 53. The detection control box 53 is electrically connected to the collector 3. The detection control box 53 is used for converting the voltage value into an electrical signal to control the operation of the multicolor laser lamps 52.

[0030] In this embodiment, from the perspective of whether voltage can be detected, an indicator is provided on a high-voltage electroscope that cannot detect the voltage value and only detects whether there is electricity in the detection interval, while a collector 3 is provided on a high-voltage electroscope with a voltage detection function that can detect the specific voltage. The collector 3 transmits the electrical signal of the specific voltage value to the detection control box 53. The detection control box 53 converts it into an electrical signal for controlling the operation of the multicolor laser lamps 52 according to the specific voltage value, and controls the corresponding multicolor laser lamps 52 to operate. The operating multicolor laser lamps 52 emit lasers of corresponding colors and irradiate on the voltage display 4, so that the voltage display 4 shows the specific voltage value.

[0031] In an alternative embodiment, the display housing 42 is mounted on the insulating handle 1 through the display support 41. The display bar 43 is fixed relative to the display housing 42 and can be directly observed. The voltage display 4 further includes a structure in the shape of the Chinese character 'Ri' composed of seven display bars 43. There are several groups of such structures. The display bars 43 are optically connected to the light receiving and energy concentrating cover 47, and several display bars 43 optically connected to one light receiving and energy concentrating cover 47 receive lasers of different colors respectively.

[0032] In this embodiment, a structure in the shape of the Chinese character 'Ri' composed of seven display bars 43 is taken as one group. The number of groups of such structures is set according to the number of digits to be displayed. When the laser irradiates on the light receiving and energy concentrating cover 47, it can transmit the light to the display bars 43. Although multiple display bars 43 are optically connected to one light receiving and energy concentrating cover 47 together, several display bars 43 optically connected to one light receiving and energy concentrating cover 47 receive lasers of different colors respectively. For example, three display bars 43 are optically connected to one light receiving and energy concentrating cover 47 together, and these three display bars 43 can receive red, green, and blue lights respectively. At this time, if the light emitted by the laser lamp is red, only the display bar 43 that can receive red light can be illuminated, and the other two display bars 43 that can receive green and blue lights do not emit light.

[0033] Embodiment 1. In an alternative embodiment, among the different groups of Chinese character "Ri" structures, the correspondingly-positioned display bars 43 are respectively and sequentially optically connected to a light receiving and concentrating cover 47 through an optical guiding channel 44, an optical guiding adapter cone 45, and a monochromatic light conductor 46;

[0034] The number of optical guiding adapter cones 45 and monochromatic light conductors 46 optically connected to a light receiving and concentrating cover 47 corresponds to the number of Chinese character "Ri" structures.

[0035] In this embodiment, when there are multiple groups of Chinese character "Ri" structures formed by the display bars 43, as Figure 4 shown, the correspondingly-positioned display bars 43 in different Chinese character "Ri" structures are respectively and sequentially optically connected to a light receiving and concentrating cover 47 through an optical guiding channel 44, an optical guiding adapter cone 45, and a monochromatic light conductor 46. The optical guiding channel 44, the optical guiding adapter cone 45, and the monochromatic light conductor 46 all have the most basic functions of an optical fiber, that is, total reflection ensures the transmission of light inside the optical fiber. The monochromatic light conductor 46 can pass light of a specific color. In this figure, three monochromatic light conductors 46 are shown. Assuming that these three monochromatic light conductors 46 can respectively pass red, green, and blue lights, at this time, a multi-color laser lamp 52 corresponding to the position of the light receiving and concentrating cover 47 emits red laser light. After the light receiving and concentrating cover 47 receives the red laser light, the red laser light can only pass through the monochromatic light conductor 46 that is permeable to this red light, while the other two monochromatic light conductors 46 are opaque. The red light continues to pass through the optical guiding adapter cone 45 and the optical guiding channel 44 and then irradiates on the display bar 43. That is to say, finally only one display bar 43 will be illuminated. According to this principle, if the multi-color laser lamp 52 that emitted red light before changes the color of the laser, assuming it emits green or blue light, then other display bars 43 will be illuminated;

[0036] In the above example description, only the case where one light receiving and concentrating cover 47 is irradiated is considered. There are a total of seven display bars 43 in one Chinese character "Ri" structure. Since the correspondingly-positioned display bars 43 are respectively and sequentially optically connected to a light receiving and concentrating cover 47 through an optical guiding channel 44, an optical guiding adapter cone 45, and a monochromatic light conductor 46, then only seven light receiving and concentrating covers 47 and seven multi-color laser lamps 52 corresponding to the positions of the light receiving and concentrating covers 47 are needed. Each multi-color laser lamp 52 will irradiate the laser on the corresponding light receiving and concentrating cover 47, and each light receiving and concentrating cover 47 has a display bar 43 optically connected thereto. Moreover, the multiple display bars 43 optically connected to one light receiving and concentrating cover 47 have the same positions in the Chinese character "Ri" structure. For Figure 4For example, among three digits, assuming that only one of the three display bars 43 optically connected to a light-receiving energy-gathering cover 47 needs to be illuminated, then it is only necessary to make the multi-color laser lamp 52 emit laser light of a specific color and irradiate it on the light-receiving energy-gathering cover 47. If two or three of the three display bars 43 optically connected to a light-receiving energy-gathering cover 47 need to be illuminated, the multi-color laser lamp 52 can cycle through three or two of the colors red, green, and blue, so as to achieve the alternating flashing of two or three display bars 43 optically connected to a light-receiving energy-gathering cover 47. If the multi-color laser lamp 52 can emit three or two colors of light, red, green, and blue, simultaneously, it can achieve the continuous illumination of two or three display bars 43 optically connected to a light-receiving energy-gathering cover 47. However, a multi-color laser lamp 52 that can emit three colors of light, red, green, and blue, simultaneously and can independently control any one or two of the colors to light up will have a relatively higher cost, a relatively larger volume, a relatively heavier weight, and a relatively more complex circuit design, and can be selectively applied;

[0037] It should be understood that Figure 4 only the three display bars 43 corresponding to each other in position in three sets of "day" - shaped structures are used as examples to show the connection structure. That is to say, regardless of the number of sets of "day" - shaped structures, at most seven light-receiving energy-gathering covers 47 need to be set, which can reduce the volume of the voltage display 4 and the voltage detector 5 and reduce the weight. However, the number of sets of "day" - shaped structures corresponds to the number of single-color light conductors 46, and the colors of light that can pass through the single-color light conductors 46 in the same set of "day" - shaped structures are all different. Correspondingly, the multi-color laser lamp 52 needs to be able to emit different light colors equal to the number of sets of "day" - shaped structures. However, for this field, three - digit voltage display is already sufficient, and the three colors red, green, and blue are the most easily distinguishable colors.

[0038] Embodiment 2. In an optional embodiment, in the same set of "day" - shaped structures, each display bar 43 is optically connected to a light-receiving energy-gathering cover 47 through an optical guide channel 44 and a single-color light conductor 46 in sequence.

[0039] In this embodiment, as Figure 5As shown, each multi-color laser lamp 52 needs to be able to emit seven colors, because in a set of sun-shaped structures, there are a total of seven display bars 43 and seven monochromatic light conductors 46, and the seven monochromatic light conductors 46 can transmit different colors of light. Assuming that the sun-shaped structure needs to emit the number "1", the two display bars 43 on the right side of the sun-shaped structure need to emit bright light. Assuming that the monochromatic light conductor 46 connected to the upper right display bar 43 can transmit red light, and the monochromatic light conductor 46 connected to the lower right display bar 43 can transmit green light, then the multi-color laser lamp 52 needs to emit red light and green light simultaneously or alternately. The advantage of this design is that the number of multi-color laser lamps 52 and light receiving energy collecting covers 47 is the same as that of the sun-shaped structure. The number of structures corresponds to that of the seven structures, and when the light receiving energy collecting cover 47 is connected to the seven display bars 43, the processing is relatively simple. If there are three groups of "日" structures, only three light receiving energy collecting covers 47 are needed, which can reduce the volume of the voltage display 4, or increase the light receiving area of ​​the light receiving energy collecting cover 47 when the volume of the voltage display 4 remains unchanged, so as to avoid the problem of laser irradiation deviation caused by slight bending of the telescopic rod body 2, and when the number of "日" structures is greater than seven groups, it is more advantageous than the first embodiment. However, when the number of groups is small, the advantage is not obvious, because the seven colors of light are easily not clearly distinguished, and slight light leakage may occur when a certain display bar 43 should not be lit.

[0040] In an optional embodiment, a buffer ring 6 is installed on the outer side of the telescopic rod body 2. Through the setting of the buffer ring 6, after the telescopic rod body 2 is contracted, the thickness of the buffer ring 6 can separate the voltage display 4 and the voltage detector 5, thereby preventing the multi-color laser light 52 from directly contacting the light receiving energy focusing cover 47.

[0041] In an optional embodiment, the display bar 43 is made of fluorescent material or phosphorescent material. When the multi-color laser light 52 flashes alternately to perform digital display, stroboscopic phenomenon is likely to occur. In order to reduce the discomfort caused by stroboscopic phenomenon, the display bar 43 is set to be a fluorescent material or a phosphorescent material. After the fluorescent material or the phosphorescent material is irradiated with light and the light source is removed, it can still continue to light up for a period of time.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
