Description

Technical Field

[0001] This utility model relates to the field of power supply technology, and in particular to a sound and light alarm device for safe distance at power supply sites. Background Technology

[0002] Most high-voltage transmission lines use poles to suspend the high-voltage transmission conductors in the air, maintaining a safe distance between the conductors and the ground. This prevents activities or ground obstacles near the high-voltage lines from contacting the conductors and causing short circuits or tripping. In areas with dense ultra-high-voltage transmission lines or crossings, the high-voltage lines are often located in the field and are susceptible to various external factors, such as construction machinery and human activities, which may damage the power facilities and consequently affect the stability and security of the power supply.

[0003] In particular, damage to high-voltage lines can severely impact power grid stability and disrupt the normal operation of the power system. Furthermore, high-voltage lines have extremely high transmission capacity; in situations with severe power blind spots, inadvertently entering the danger zone of a high-voltage line can easily result in injury or death.

[0004] Existing technologies use external damage alarms to reduce or avoid line faults caused by external forces, ensuring power supply stability. However, existing alarms are generally installed on high-voltage lines, causing difficulties for installation workers. Furthermore, strong winds can easily cause alarms at designated locations to be blown away, sliding along the high-voltage line, thus failing to effectively warn and protect against approaching high-voltage lines. Utility Model Content

[0005] In view of this, the present invention aims to provide a power supply site safety distance audible and visual alarm device, which can keep the alarm device in a fixed position, facilitate installation, and effectively ensure the warning and protection function of high-voltage lines.

[0011] A connecting member is also provided between the supporting part and the curling part. When the driving component drives the two clamping arms to come closer to each other, the ends of the two curling parts move away from the center of the covering space, the supporting part moves upward, and the supporting part and the two curling parts form a clamping space.

[0012] Furthermore, the drive assembly includes a drive unit connected to the mounting base, two links pivotally connected to the mounting base, and a connecting shaft pivotally connected to both links, with the power output end of the drive unit connected to the connecting shaft;

[0013] The other ends of the two connecting rods are pivotally connected to the two clamping arms, respectively.

[0014] Furthermore, a limiting plate is provided in the middle of the mounting base, the limiting plate extends from the mounting base toward the clamping arm, and two limiting plates are respectively provided on both sides of the clamping arm along the thickness direction of the clamping arm;

[0015] The limiting plate is provided with a limiting groove, the connecting shaft is disposed in the limiting groove, and the driving unit drives the connecting shaft to move.

[0016] Furthermore, each end of the connecting shaft is provided with two cross-pivotally connected connecting rods, and the connecting rods are located on both sides of the mounting base along the thickness direction of the mounting base;

[0017] The mounting base is provided with a first pin at each end, and the connecting rods on both sides are pivotally connected to the two first pins respectively.

[0018] Furthermore, a hinge shaft is provided between the two clamping arms, and the hinge shaft passes through and connects between the two limiting plates;

[0019] The clamping arm is also provided with a protruding lifting lug, and the lifting lug is formed with a through hole along the thickness direction of the clamping arm. A second pin is provided in the through hole, and the second pin is respectively connected to the connecting rods on both sides.

[0020] Furthermore, the hinge shaft is connected to several mounting cylinders, and the support part includes a post inserted into the mounting cylinder and a support plate connected to the upper end of the post.

[0021] Furthermore, a guide post is provided below the insertion post, and a telescopic spring is provided between the guide post and the mounting cylinder, with the telescopic spring abutting between the insertion post and the hinge shaft.

[0022] Furthermore, the end of the curled portion is provided with a connecting plate, which is pivotally connected to the connector;

[0023] The elastomer further includes a mounting portion connected to the curled portion, and the mounting portion is bolted to the clamping arm.

[0024] When the two clamping arms are clamped, the two opposing curled portions abut against each other, and the clamping space is an annular closed ring.

A coiled portion protruding towards the center is provided within the covered space, forming a clamping space with the supporting portion. When the drive component drives the two clamping arms closer together, the ends of the two coiled portions move away from the center of the covered space, causing the supporting portion to move upwards, thereby confining the high-voltage line within the clamping space. This ensures a secure connection between the alarm and the high-voltage line, guarantees accurate positioning of the alarm, and effectively ensures its function.

[0028] Furthermore, by setting a drive unit on the mounting base, the drive unit drives the connecting shaft to move linearly while the two hinged connecting rods rotate relative to the connecting shaft, so that the two clamping arms move closer or further apart, thereby realizing the disassembly and installation of the alarm. The structure is simple and easy to implement. Attached Figure Description

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] This embodiment relates to a power supply site safety distance audible and visual alarm 2. Overall, the alarm 2 includes a mounting base 1, an alarm 2 connected below the mounting base 1, a drive assembly 3 connected to the mounting base 1, and a clamping assembly 4 pivotally connected to the drive assembly 3. The clamping assembly 4 includes two relatively pivoting clamping arms 401, an elastic body 402 connected to the clamping arms 401, and a support portion 403 located at the pivot center of the clamping arms 401. A covering space 404 is formed between the two clamping arms 401, and the two elastic bodies 402 are disposed opposite each other within the covering space 404. Each elastic body 402 includes a curled portion 4021 protruding towards the center of the covering space 404. A connecting member 405 is also provided between the supporting part 403 and the curling part 4021. When the driving assembly 3 drives the two clamping arms 401 to approach each other, the ends of the two curling parts 4021 move away from the center of the covering space 404, and the supporting part 403 moves upward. The supporting part 403 and the two curling parts 4021 form a clamping space 406.

[0047] The power supply site safety distance audible and visual alarm 2 in this embodiment uses a drive assembly 3 to drive two clamping arms 401 closer together, binding the high-voltage line within the enclosure space 404. A coiled portion 4021 protruding towards the center is provided within the enclosure space 404, forming a clamping space 406 with the support portion 403. When the drive assembly 3 drives the two clamping arms 401 closer together, the ends of the two coiled portions 4021 move away from the center of the enclosure space 404, causing the support portion 403 to move upwards, thereby confining the high-voltage line within the clamping space 406. This ensures a secure connection between the alarm 2 and the high-voltage line, guarantees accurate positioning of the alarm 2, and effectively ensures its function.

[0048] Based on the above overall introduction, an exemplary structure of the power supply site safety distance audible and visual alarm 2 in this embodiment is as follows: Figures 1 to 2 As shown, in practical applications, the alarm 2 is delivered to a high-voltage line in the air by a drone. During delivery, the clamping arm 401 is in an open state, and there is an opening above the covering space 404. When the opening of the covering space 404 is aligned with the high-voltage line, the alarm 2 is moved upward by the drone, and the high-voltage line is placed inside the covering space 404.

[0049] Preferably, such as Figures 1 to 2 As shown, the mounting base 1 has a base 11 at its lower part, and a microwave-sensing audible and visual alarm 2 is installed inside the base 11. The drive unit 301 is connected inside the base 11, and its output shaft passes through the mounting base 1 and extends towards the clamping assembly 4.

[0050] As a preferred embodiment, such as Figures 1 to 2As shown, the drive assembly 3 includes a drive unit 301 connected to the mounting base 1, two connecting rods 302 pivotally connected to the mounting base 1, and a connecting shaft 303 pivotally connected to both connecting rods 302. The power output end of the drive unit 301 is connected to the connecting shaft 303. The other ends of the two connecting rods 302 are pivotally connected to two clamping arms 401 respectively.

[0051] By setting a drive unit 301 on the mounting base 1, the drive unit 301 drives the connecting shaft 303 to move linearly, while the two hinged connecting rods 302 rotate relative to the connecting shaft 303, so that the two clamping arms 401 move closer or further apart, thereby realizing the disassembly and installation of the alarm 2. The structure is simple and easy to implement.

[0052] Furthermore, such as Figures 1 to 2 As shown, a limiting plate 5 is provided in the middle of the mounting base 1. The limiting plate 5 extends from the mounting base 1 toward the clamping arm 401. Along the thickness direction of the clamping arm 401, two limiting plates 5 are respectively provided on both sides of the clamping arm 401. A limiting groove 501 is provided on the limiting plate 5. The connecting shaft 303 is provided in the limiting groove 501. The driving unit 301 drives the connecting shaft 303 to move. In this embodiment, the driving unit 301 is an electric cylinder.

[0053] As one specific implementation method, such as Figure 1 As shown in the figure, the connecting shaft 303 has two cross-pivotally connected connecting rods 302 at both ends. Along the thickness direction of the mounting base 1, the connecting rods 302 are located on both sides of the mounting base 1. The mounting base 1 has first pins 6 at both ends, and the connecting rods 302 on both sides are pivotally connected to the two first pins 6 respectively. This arrangement can improve the force stability of the clamping arm 401 during movement, as well as the clamping force when the clamping arm 401 clamps.

[0054] In addition, such as Figures 1 to 2 As shown, a hinge shaft 7 is provided between the two clamping arms 401. The hinge shaft 7 passes through and connects between the two limiting plates 5. The clamping arm 401 is also provided with a protruding lifting lug 4011. A through hole is formed on the lifting lug 4011 along the thickness direction of the clamping arm 401. A second pin 9 is provided in the through hole. The second pin 9 is connected to the connecting rods 302 on both sides respectively.

[0055] In addition, such as Figure 1 and Figure 2 As shown, a plurality of mounting cylinders 8 are connected to the hinge shaft 7. The support part 403 includes a post 4031 inserted into the mounting cylinder 8 and a support plate 4032 connected to the upper end of the post 4031. The support plate 4032 has pivot holes 4033 at both ends that are connected to the connector 405. The connector 405 is pivotally connected to the support plate 4032 through the third pin 10.

[0056] Furthermore, such as Figures 3 to 4As shown, a guide post 4034 is provided below the insertion post 4031, and a telescopic spring 4035 is provided between the guide post 4034 and the mounting cylinder 8. The telescopic spring 4035 abuts against the insertion post 4031 and the hinge shaft 7. By setting the guide post 4034, the position accuracy of the support plate 4032 when it rises is ensured, and the locking effect is guaranteed.

[0057] As a preferred embodiment, such as Figures 3 to 4 As shown, the end of the coiled portion 4021 is provided with a connecting plate 4036, which is pivotally connected to the connecting member 405. The elastic body 402 also includes a mounting portion 4022 connected to the coiled portion 4021. The mounting portion 4022 is bolted to the clamping arm 401. When the two clamping arms 401 are clamped, the two opposing coiled portions 4021 abut against each other, and the clamping space 406 is an annular closed ring. The elastic member is made of spring steel. When the two coiled portions 4021 abut against each other, the connecting plate below tilts upwards due to the elastic abutment of the coiled portions 4021, thereby driving the connecting member 405 to move upwards, and then the supporting portion 403 clamps the high-voltage line with the two coiled portions 4021. In other embodiments, high-voltage lines of different specifications can be simulated on the ground to adjust the compression springs with different elastic forces.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
