Technical Field

[0001] The invention relates to the technical field of overhead line warning, and in particular to a laser indicator. Background Art

[0002] Distribution lines include cable lines and overhead lines. Cable lines were newly built in recent years and have relatively complete functional configurations, while overhead lines have been in operation for a long time and have inherent deficiencies in failure rate and inspection. For example, live displays are standard in cable line switch cabinets, but there are no live displays in overhead lines. During production operations, we often have to maintain and inspect overhead circuits. When inspectors are inspecting, they need to repeatedly inspect between overhead lines and the ground. Such an inspection process is relatively complicated and time-consuming. Summary of the invention

[0003] The purpose of the present invention is to provide a laser pointer to solve the problem that the existing overhead circuit is time-consuming to repair.

[0004] To achieve this purpose, the present invention adopts the following technical solutions: The present invention provides a laser pointer, comprising a laser component, an electric control component, a limiter component and an indicator body, wherein a first mounting baffle is arranged in the indicator body, the first mounting baffle forms a first mounting cavity, the laser component is mounted on the lower side of the first mounting baffle, the limiter component is mounted on the upper side of the first mounting baffle, the outer side of the indicator body is wrapped with a solar film, and the limiter component, the electric control component, the solar film and the laser component are electrically connected in sequence;

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0020] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0022] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0023] Since the overhead lines were erected at an early time, there are no live displays on the overhead lines like cable lines. Therefore, during the later maintenance process, maintenance personnel are required to repeatedly climb on the brackets on the overhead lines, which wastes time and reduces maintenance efficiency. At the same time, climbing also increases the risk of maintenance personnel falling.

[0024] Embodiment 1

[0025] In order to solve the above problems, Figure 1 to Figure 2 As shown, the present invention provides a laser pointer, comprising a laser component 7, an electric control component 3, a limit component 4 and an indicator body 2, wherein a first mounting partition 1 is arranged in the indicator body 2, the first mounting partition 1 forms a first mounting cavity, the laser component 7 is mounted on the lower side of the first mounting partition 1, the limit component 4 is mounted on the upper end of the first mounting partition 1, the outer side of the indicator body 2 is wrapped with a solar film, and the limit component 4, the electric control component 3, the solar film and the laser component 7 are electrically connected in sequence;

[0026] The limiting component 4 includes a first limiting member and a second limiting member. The first limiting member, the second limiting member and the first mounting partition 1 form an installation area 6. The wires 5 can be passed through the installation area 6. The limiting component 4 abuts against the wires 5. The first limiting member is electrically connected to the second limiting member through the wires 5.

[0027] After the electric wires 5 are passed through the installation area 6, the installation is completed. During the day, the solar film on the outer wall of the indicator body 2 absorbs energy through the irradiation of sunlight, so that the capacitor inside the electric control component 3 is fully charged, so that the laser light source connected to the electric control component 3 emits light. The staff on the ground can directly observe the light with the naked eye, and then directly judge the operating status of the overhead line, thereby reducing the number of climbing times for the staff and improving work efficiency.

[0028] The first limiter and the second limiter of the present invention both include a flip portion 42 and a support portion 41 . One end of the flip portion 42 is connected to the support portion 41 , and the other end of the flip portion 42 flips around the support portion 41 toward the installation area 6 .

[0029] During the installation of the laser pointer, the wire 5 is located above the laser pointer, and the wire 5 is embedded from between the two flip parts 42 of the first limit piece and the second limit piece into the installation area 6, so that the wire 5 is finally located in the installation area 6. At this time, the first limit piece can be electrically connected to the second limit piece through the wire 5. After conduction, the entire electronic control component 3 will light up the laser light source, and the laser light source will flash under the control of the single-chip microcomputer in the electronic control component 3, so that the inspection personnel on the ground can directly observe the flashing of the laser light source, and then directly infer the working status of the overhead circuit on the ground.

[0030] The flipping part 42 of the present invention is a one-way spring, and the flipping part 42 can automatically reset so that the flipping part 42 and the first mounting partition 1 are parallel to each other. When the flipping parts 42 on both sides of the wire 5 are flipped to the maximum angle, the laser pointer will continue to move upward. At this time, the position where the front end of the flipping parts 42 on both sides contact the wire 5 is already above the horizontal diameter cross section of the wire 5. Since the wire 5 is in the mounting area 6 at this time, the flipping part 42 will return to the normal position to prevent the wire 5 from being separated from the mounting area 6, so that the laser pointer will not be separated from the wire 5 due to gravity or other external factors. A one-way spring is installed between 42 and the support part 41. When the upper side of the flip part 42 contacts the wire 5, the flip part 42 will rotate into the installation area 6. At this time, the wire 5 continues to move downward relative to the laser pointer. When the front end of the flip part 42 is higher than the maximum diameter cross-section of the wire 5, the one-way spring controls the flip part 42 to return to the center, and the wire 5 is confined in the installation area 6. When installing for the first time, the staff only needs to push the laser pointer upward under the wire 5 to install the laser pointer on the overhead line. It is simple and convenient, and the installation efficiency is improved.

[0031] A main spring 11 is installed at the upper end of the first mounting baffle 1 of the present invention, and the wire 5 can abut between the flip part 42 and the main spring 11. In order to make the laser pointer stably installed on the wire 5, a main spring 11 is also installed on the lower side of the mounting area 6. When the wire 5 enters the mounting area 6, the main spring 11 will be compressed. When the flip part 42 returns to its original position, the main spring 11 will also push the wire 5 upward and restrict the wire 5 between the main spring 11 and the flip part 42. This will make the laser pointer more stable after installation. By changing the height of the main spring 11, it can adapt to overhead wires 5 of different diameters, making the laser pointer more versatile.

[0032] The laser component 7 of the present invention includes a laser light source, which is electrically connected to the electronic control component 3 and is charged by solar energy to provide power for lighting the laser light source, effectively avoiding the laser light source from being extinguished due to insufficient energy, thereby improving the reliability and service life of the laser indicator.

[0033] The laser assembly 7 of the present invention includes a support member 71, a receiving tube 72 is formed in the center of the support member 71, a laser light source is installed in the center of the receiving tube 72, a connecting plate 711 extends outward from the outer wall of the receiving tube 72, and the connecting plate 711 abuts against the inner wall of the indicator body 2. The laser light source is fixed to the bottom of the first mounting partition 1 by the support member 71, and the laser light source can be suspended in the cavity by abutting against the inner wall of the indicator body 2, so that the laser light source has higher stability.

[0034] It should be particularly noted that the connecting plates 711 include at least two groups, and the connecting plates 711 are installed on the outer wall of the accommodating tube 72 at equal intervals in the circumferential direction. The more connecting plates 711 there are, the higher the stability of the laser light source.

[0035] The laser light source of the present invention is green, and green has higher penetrating power under foggy or haze conditions. The green light source can penetrate haze or white fog, making it more convenient for ground inspection personnel to observe and making it easier to observe the laser light source without being affected by external weather factors.

[0036] By installing the diamond-shaped light guide plate 8 on the lower side of the support member 71, the line beam of the laser light source can be more concentrated, and the penetrating power of the laser light source can be stronger, thereby improving the display effect of the laser light source and reducing the impact of weather factors.

[0037] The light guide plate 8 of the present invention and the indicator body 2 form a plug-in cavity 9, in which an insulating rod can be plugged. The laser indicator can be plugged at the upper end through the insulating rod. The insulating rod is manually held and extended upward to abut against the electric wire 5, and the laser indicator is installed on the overhead line. This reduces the climbing distance of the workers, reduces the danger, and improves the installation efficiency. The connection with the electric wire 5 can be completed only by moving upward.

[0038] The indicator body 2 includes an upper shell 21 and a lower shell 22. The upper shell 21 is snapped into the lower shell 22. A sealing ring 10 is installed between the upper shell 21 and the lower shell 22 to prevent external liquid from invading and damaging the electronic control component 3, thereby extending the service life of the laser indicator. At the same time, a sealing ring 10 is also sleeved between the light guide plate 8 and the lower shell 22 to prevent external water vapor from invading and extend the service life of the laser indicator.

[0039] Embodiment 2

[0040] The first limit member and the second limit member of the present invention can also be a rotating hinge, and the wire 5 can pass through the rotating blades into the installation area 6, and then the hinge automatically closes to lock the wire 5 in the installation area 6, and the hinge can also play a one-way opening and closing role.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
