Description

Technical Field

[0001] The invention relates to the technical field of power grid protection, in particular to a protection device for an interleaved power grid. Background Art

[0002] The power grid consists of substations and transmission lines of different voltage levels. Its function is to transmit, control and distribute electric energy. The connection mode of the power grid can be roughly divided into two categories: without backup and with backup.

[0003] The non-backup wiring includes single-circuit radial, trunk and chain networks. The backup wiring includes double-circuit radial, trunk, chain, ring and two-end power supply networks. The non-backup wiring is simple, economical and easy to operate, but the power supply reliability is poor. The automatic reclosing device of the overhead line can make up for the above shortcomings to a certain extent. On the contrary, the power supply with backup wiring is highly reliable, and the failure or maintenance of one line generally does not affect the power supply to users, but the investment is large and the operation is more complicated. Among them, the ring power supply and the two-end power supply are more commonly used.

[0004] Patent document with announcement number CN111034707B discloses a staggered power grid protection device. By setting a crossbar, a first spring, a hammer, a support rod, a second spring and a gong plate, when a user uses the device, a driving motor drives the crossbar, the first spring and the hammer to start rotating. The hammer hits the gong plate during rotation and makes a sound. In this way, there are constant impact sounds in the area where the device is located, and birds in the area cannot feel safe. The possibility of birds building nests here is greatly reduced, which saves users from troubles and is convenient for users to use.

[0005] At the same time, by setting the horizontal plate, the diopter, the connecting plate, the sticking plate and the reflector, when the user uses the device, the diopter and the reflector emit light, and when the rotating shaft starts to rotate, the diopter and the reflector continuously reflect the light, and the birds nearby are affected by the shaking light and will not be willing to approach.

[0006] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0007] The staggered power grid protection device uses folding mirrors and reflectors to reflect light, which can reduce the risk of birds approaching the area where the equipment is located. However, in actual application, due to the wide coverage of the power grid and the large number of transmission lines, the use of equipment warnings is limited by the size of the equipment and the application terrain, and is difficult to apply to various areas of the power grid.

DETAILED DESCRIPTION

[0033] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0034] Embodiment 1:

[0035] This embodiment introduces a specific structure of a protection device for a staggered power grid. Figure 1-Figure 4 , Figure 7 , Figure 8 As shown, it includes a reflective tube 6 and a transparent glass tube 1 sleeved on the outside of the reflective tube 6, and the outer walls of both ends of the reflective tube 6 are processed with a plurality of reflective grooves 10, the plurality of reflective grooves 10 are all in a pyramid shape, and the inner walls of the plurality of reflective grooves 10 are all processed into reflective mirror surfaces;

[0036] Among them, by making multiple reflective grooves 10 equally spaced around the center of the reflective tube 6 and distributed in multiple circles, and two adjacent circles are arranged complementary to each other, the gaps between the multiple reflective grooves 10 are eliminated, and when the cable 4 passes through the inside of the reflective tube 6, the multiple reflective grooves 10 can be used to reflect light in good light conditions, thereby producing a dazzling effect to drive away birds (because the multiple reflective grooves 10 are distributed at different positions, and because of the inclination angle of the inner wall of the reflective groove 10, the light is supported to be reflected to different positions, ensuring the range of light reflection);

[0037] Secondly, in order to protect the multiple reflective grooves 10, the debris (including rainwater, sand and gravel) collected inside the reflective grooves 10 is limited. Figure 2 and Figure 4 As shown, the outside of the reflective tube 6 is sleeve-connected with the transparent glass tube 1, one end of the reflective tube 6 is provided with a buckle frame 5, and the other end of the reflective tube 6 is processed with a bracket 3. The surface of one side of the bracket 3 is processed with a limiting ring A9, and one side of the buckle frame 5 is processed with a limiting ring B14. By inserting the two ends of the transparent glass tube 1 into the outside of the limiting ring B14 and the limiting ring A9 respectively, the outer wall of the transparent glass tube 1 is flush with the outer walls of the bracket 3 and the buckle frame 5, and the transparent glass tube 1 can be used to block debris and ensure that light can pass through the inside of the transparent glass tube 1.

[0038] Furthermore, after the reflective tube 6 and the transparent glass tube 1 are connected with the bracket 3 and the buckle frame 5, the overall cross-section is C-shaped, and two limiting strips 7 are integrally formed on both sides of the opening of the C-shaped transparent glass tube 1. One side of the two limiting strips 7 is respectively fitted with the two side surfaces of the opening of the C-shaped reflective tube 6, and one end of the two limiting strips 7 is protruded from one end of the transparent glass tube 1 and forms an extension piece 8 respectively, and one side of the two extension pieces 8 is respectively fitted with the two side surfaces of the opening of the C-shaped bracket 3;

[0039] At the same time, the cross section of the buckle frame 5 is set to be C-shaped, and the limiting pieces 11 are processed on both sides of the opening of the C-shaped buckle frame 5. By making the one side surface of the two limiting pieces 11 fit the two side surfaces of the opening of the C-shaped reflective tube 6 respectively, the reflective tube 6 and the transparent glass tube 1 can be supported to buckle with the outside of the cable 4 in a direction perpendicular to the cable 4 after being connected with the bracket 3 and the buckle frame 5, so as to facilitate the connection of the reflective tube 6 to the outside of the cable 4.

[0040] Furthermore, in order to ensure the connection effect between the buckle frame 5 and the reflective tube 6, the buckle frame 5 and the bracket 3 are stably positioned to position the transparent glass tube 1, such as Figure 7 and Figure 8As shown, a limiting ring groove 12 is formed on the inner wall of the buckle frame 5, and a limiting buckle ring 13 is processed on the surface of one end of the reflective tube 6. By making the limiting buckle ring 13 fit in the inside of the limiting ring groove 12, when the buckle frame 5 is sleeved on the outside of one end of the reflective tube 6, the buckle frame 5 can be buckled to the outside of the limiting buckle ring 13 through the limiting ring groove 12, thereby achieving the connection and fixing effect of the buckle frame 5 and the reflective tube 6.

[0041] By adopting the above technical solution:

[0042] The above design provides a reflective tube 6 with a plurality of reflective grooves 10 on the outer wall, and uses a buckle frame 5 to be sleeved on one end of the reflective tube 6, and fixes the transparent glass tube 1 between the bracket 3 and the buckle frame 5. When the reflective tube 6 and the transparent glass tube 1 are connected to the bracket 3 and the buckle frame 5, the reflective tube 6 related structure can be made into a C shape as a whole. By buckling the reflective tube 6 to the outside of the cable 4, the reflective tube 6 can be fixed to the outside of any cable 4 in the power grid, which is convenient for arranging the reflective tube 6 to any position outside the cable 4. Based on the reflection of sunlight by the inner wall of the reflective groove 10, birds close to the cable 4 are dazzled by the reflected light, so as to prevent the birds from staying on the cable 4.

[0043] Embodiment 2:

[0044] Based on Example 1, this example introduces the specific structure of the transparent glass tube 1. Figures 4 to 6 As shown, three whistle structures 2 are arranged on the outer wall of the middle part of the transparent glass tube 1, and the three whistle structures 2 all include a whistle tube 204, and two blowing cylinders 202 are processed inside both ends of the whistle tube 204;

[0045] The three whistle structures 2 are all perpendicular to the axis of the transparent glass tube 1 and are equally spaced around the center of the transparent glass tube 1. By making the two air cylinders 202 parallel to each other and the air cylinders 202 at both ends of the whistle tube 204 facing each other, when wind passes through the inside of the whistle tube 204, the two air cylinders 202 can vibrate in the air to generate noise to drive away approaching birds.

[0046] Secondly, in order to increase the wind speed of the wind flowing through the whistle pipe 204, as Figure 6 As shown, both ends of the whistle tube 204 are embedded with a sounding piece 201, and the sounding piece 201 is processed with an air guide slot inside. By setting the cross section of one end of the air guide slot to be circular and the cross section of the other end to be rectangular, the two air cylinders 202 are parallel to the rectangular end of the air guide slot. When the wind passes through the inside of the sounding piece 201, the passage inside the air guide slot becomes smaller and the flow rate is increased, so that the two air cylinders 202 in a parallel state are more likely to vibrate, thereby generating noise;

[0047] Furthermore, in order to guide the wind entering the whistle pipe 204 through the sound plate 201 to flow smoothly from the inside of the whistle pipe 204 to the outside, Figure 5 As shown, the middle inner wall of the whistle tube 204 is processed with an air guide seat 203 and an air outlet. The cross-section of the whistle tube 204 is triangular. The air guide seat 203 and the air outlet are arranged opposite to each other, the air guide seat 203 is located on the side of the transparent glass tube 1 close to the center of the circle, and the air outlet is located on the side of the transparent glass tube 1 away from the center of the circle. When wind passes through the inside of the sound-producing piece 201 and causes the two air cylinders 202 to oscillate, the wind is guided by the inclined surface of the air guide seat 203 and flows out to the inside of the air outlet.

[0048] By adopting the above technical solution:

[0049] The above-mentioned design processes three whistle structures 2 on the middle outer wall of the transparent glass tube 1, and makes the three whistle structures 2 equally spaced around the center of the transparent glass tube 1. When the air flow rate increases (normal wind phenomenon) and blows through the inside of one end of the whistle tube 204 on the whistle structure 2, the air is accelerated through the air guide groove inside the sound plate 201 and blows toward the two air cylinders 202 in a parallel state. When the air cylinders 202 oscillate and generate noise, the wind flows out from the inclined surface of the air guide seat 203 through the air outlet on the whistle tube 204, which can drive away birds approaching the cable 4 and is easy to use on the outside of the cable 4 erected in the air.

[0050] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
