Description

Technical Field

[0001] This utility model relates to the technical field of cable protection devices, specifically to a rodent repellent device based on overhead cables. Background Technology

[0002] Currently, during power line construction, whether in urban areas or remote mountainous regions, most power fiber optic cables are laid overhead. This is primarily for safety and to avoid impacting ground structures, as well as to prevent damage from animals. However, especially in remote mountainous areas where there are many animals, overhead installation is insufficient to address the challenges posed by rodents with strong climbing abilities. Rats, squirrels, and other animals can easily climb poles or towers, leading to damage to the fiber optic cables, fiber breakage, and communication disruptions, significantly impacting the safe operation of the power grid.

[0003] To address the aforementioned issues, existing technology discloses a rodent-repelling device for overhead optical cables, with publication number CN110692620A. This device includes a first support plate, a second support plate, and a sheath assembly. Semi-circular slots are respectively provided on one side of the first and second support plates. One end of each side of the first and second support plates is hinged, and the other end is connected by bolts. After the first and second support plates are fitted together, the slots on the first and second support plates form circular mounting holes for accommodating utility poles. Both the first and second support plates have sheath assemblies on their lower surfaces. Each sheath assembly includes a support rod and a sheath plate. The upper end of the support rod is connected to the lower surface of the first / second support plate, and the lower end of the support rod is connected to the sheath plate. The sheath plate has an arc-shaped structure with the arc facing downwards, and several spikes are provided on its outer surface. Side guards are provided on the left and right sides of the sheath plate, and the side guards are connected to the sheath plate via a connecting rod assembly. An inclined solar panel is provided on the upper surface of the first support plate, and a battery is connected to the solar panel via wires. The battery is connected to a rodent repellent. The aforementioned patent document uses a solar panel and an electric rodent repellent, resulting in too many components, a complex structure, and, most importantly, high cost, making it unsuitable for widespread application.

[0004] The prior art also discloses a patent with publication number CN216851170U entitled "A Rodent Repellent Device for Overhead Cables." It includes a cylinder fitted onto a cable and a rotating component positioned between the cable and the cylinder to support the cylinder's rotation. The cylinder is composed of a pair of arc-shaped cover plates. The rotating component includes an arc-shaped bracket fixed to the inner wall of the cover plate and several rollers rotatably positioned on the inner arc surface of the bracket. When the two cover plates are combined, the rotating components on both sides close together and surround the cable. The rotation axis of the rollers is parallel to the central axis of the cylinder. Rotating components are provided at both ends of the cover plate along its length. Bosses are provided on the outer arc surfaces at both ends of the cover plates, and the two cover plates are fixed by fasteners mounted on the bosses. The fasteners include through holes at both ends of the boss's circumference, a copper insert in one of the through holes, and a bolt passing through the through hole of one cover plate and engaging with the copper insert of the other cover plate. The mating edges on both sides of the cover plates are respectively provided with a protruding edge and a groove. When the two cover plates are closed, the protruding edge of one cover plate engages with the groove of the other cover plate. Although the aforementioned patent documents have a simple structure and low cost, small rodents may walk along the center line of the cylinder and pass through it, so the rodent-repelling effect is poor. Utility Model Content

[0005] The purpose of this invention is to provide a rodent repelling device based on overhead cables that is simple in structure, low in cost, and has a good rodent repelling effect.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A rodent-repelling device based on an overhead cable includes a rodent-repelling sleeve, a step-rotating drop plate, and a rodent-traffic path blocking part. The step-rotating drop plate and the rodent-traffic path blocking part are disposed on the rodent-repelling sleeve, which is inserted through the overhead cable. The rodent-traffic path blocking part is used to block the rodent-traffic path on the rodent-repelling sleeve to drive the rodent onto the step-rotating drop plate. When the rodent is on the step-rotating drop plate, under the rodent's own weight, the step-rotating drop plate and the rodent-repelling sleeve rotate together around the overhead cable at an angle, so that the rodent falls off the step-rotating drop plate and falls from the overhead cable.

[0008] Furthermore, the step-rotating drop plate is provided with 1 to 3 units.

[0009] Furthermore, there are two step-rotating drop plates: a front step-rotating drop plate and a rear step-rotating drop plate. The surfaces of both the front and rear step-rotating drop plates are curved. The left end of the front step-rotating drop plate is located in front of the left end of the rodent-repelling sleeve, and the right end is located behind the right end of the rodent-repelling sleeve. One side of the front step-rotating drop plate is connected to the wall of the rodent-repelling sleeve. The left end of the rear step-rotating drop plate is located behind the left end of the rodent-repelling sleeve, and the right end is located in front of the right end of the rodent-repelling sleeve. One side of the rear step-rotating drop plate is connected to the wall of the rodent-repelling sleeve.

[0010] Furthermore, the section of the front and rear step-rotating drop plates that spans the rodent-repelling sleeve is the rodent-traffic path blocking part.

[0011] Furthermore, the connection points between the front and rear step-rotating drop plates and the surface of the rodent-repellent sleeve form a spiral curve.

[0012] Furthermore, the length of the rodent-repellent sleeve is not less than 20cm; the height of the rear step-rotating drop plate is not less than 3cm.

[0013] Furthermore, there are two step-rotating drop plates, and the surfaces of the two step-rotating drop plates are planar structures; the two step-rotating drop plates are symmetrically arranged on both sides of the rodent-repelling sleeve, and the rodent-traffic path blocking part is located at the top of the rodent-repelling sleeve.

[0014] Furthermore, the blocking part of the mouse path is a conical structure that is thicker at the bottom and thinner at the top.

[0015] Furthermore, the bottom of the rodent-repellent sleeve is provided with a counterweight, which is used to keep the two step-rotating drop plates in a horizontal state.

[0016] Furthermore, the rodent-repellent sleeve is divided into a left section, a middle section, and a right section, with the rodent-traveling path blocking part located in the middle section of the rodent-repellent sleeve. This design allows rodents to enter from both ends of the sleeve's wall surface, effectively repelling small animals on overhead cables at both ends of the sleeve.

[0017] The beneficial effects of this utility model are as follows:

[0018] The innovative structure of this application utilizes a rodent-tracing obstruction section to block the rodent's path on the rodent-repelling sleeve, thereby driving the rodent onto the rotating drop platform. When the rodent is on the rotating drop platform, under its own weight, the rodent-repelling sleeve rotates around the overhead cable, causing the rodent to detach from the rotating drop platform and fall from the overhead cable. This application greatly improves the rodent-repelling effect, and its simple structure and low cost make it suitable for widespread application. Attached Figure Description

[0028] Example 1

[0029] like Figure 1 , 2As shown in Figure 3, a rodent-repelling device based on overhead cables includes a rodent-repelling sleeve 1, a step-on rotating drop plate, and a rodent-traffic-blocking part 5. The step-on rotating drop plate and the rodent-traffic-blocking part are disposed on the rodent-repelling sleeve. Specifically, there are two step-on rotating drop plates, namely a front step-on rotating drop plate 2 and a rear step-on rotating drop plate 3, and the surfaces of the front step-on rotating drop plate 2 and the rear step-on rotating drop plate 3 are curved. The left end of the drop plate 2 is located in front of the left end of the rodent-repelling sleeve 1. The right end of the front-step rotating drop plate 2 is located behind the right end of the rodent-repelling sleeve 1, and one side of the front-step rotating drop plate 2 is connected to the wall of the rodent-repelling sleeve 1. The left end of the rear-step rotating drop plate 3 is located behind the left end of the rodent-repelling sleeve 1, and the right end of the rear-step rotating drop plate 3 is located in front of the right end of the rodent-repelling sleeve 1. One side of the rear-step rotating drop plate 3 is connected to the wall of the rodent-repelling sleeve 1. The rodent-repelling sleeve 1 is inserted into the overhead cable 4.

[0030] The section of the front and rear rotating drop plates 2 and 3 that spans the rodent-repelling sleeve 1 is the rodent path blocking part 5. The rodent path blocking part 5 is used to block the rodent's path on the rodent-repelling sleeve 1, thereby driving the rodent onto the rotating drop plate. The rotating drop plate is used so that when the rodent is on the rotating drop plate, under the rodent's own weight, it drives the rotating drop plate and the rodent-repelling sleeve to rotate at an angle around the overhead cable, so that the rodent detaches from the rotating drop plate and falls from the overhead cable.

[0031] The rodent-repellent sleeve 1 is divided into a left section, a middle section, and a right section, with the rodent-traveling path blocking part 5 located in the middle section of the rodent-repellent sleeve 1. This design allows rodents to enter from both ends of the sleeve, effectively repelling small animals on overhead cables at both ends of the sleeve.

[0032] In addition, the connection points between the front and rear step-rotating drop plates and the surface of the rodent-repelling sleeve form a spiral curve. The length of the rodent-repelling sleeve is not less than 20cm, and the length should be at least twice the length of the rodent's body. If it is too short, it will not achieve the rodent-repelling effect, and it cannot be too long, generally not exceeding 100cm, because if it is too long, the sensitivity of the rodent-repelling sleeve to rotation under force will decrease, and it will also result in high cost and low practicality. The height of the rear step-rotating drop plate is not less than 3cm. If the height is too low, the rodent-moving path blocking part 5 will not play a blocking role.

[0033] Example 2

[0034] like Figure 4 , 5As shown, a rodent-repelling device based on overhead cables includes a rodent-repelling sleeve 1, a stepped rotating drop plate 6, and a rodent-traffic path blocking part 5. Two stepped rotating drop plates 6 are provided, each with a planar surface. The two plates 6 are symmetrically arranged on both sides of the rodent-repelling sleeve 1, and the rodent-traffic path blocking part 5 is located at the top of the sleeve. The sleeve 1 is divided into a left section, a middle section, and a right section, with the blocking part 5 located in the middle section. This design allows rodents to enter from both ends of the sleeve, effectively repelling small animals on the overhead cables at both ends.

[0035] The rodent-traveling obstruction 5 is a conical structure that is thicker at the bottom and thinner at the top. This conical structure, combined with the two step-rotating drop plates 6 of the planar structure, makes the passage very wide and has a higher inducing effect on the rodent, so that the rodent will resolutely move forward along the rodent-repelling sleeve 1, thereby causing the rodent to fall from the overhead cable and achieve the purpose of repelling it.

[0036] Additionally, if necessary, a counterweight 7 can be provided at the bottom of the rodent-repelling sleeve 1. The counterweight 7 is used to keep the two step-rotating drop plates in a horizontal state. The counterweight 7 is only for leveling purposes. Its weight should be light and not too heavy. It should ensure that the rodent-repelling sleeve can rotate when the rodent is on the step-rotating drop plate. The weight of the counterweight should not affect the sensitivity of the rodent-repelling sleeve to rotate under force.

[0037] Furthermore, those skilled in the art can combine and integrate the different embodiments or examples described herein, as well as the features of those different embodiments or examples, without contradiction. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
