Abstract

The present invention provides a special marine engineering power cable for preventing rats and ants. By means of the arranged support rods, support frames, rotating cylinders, scraping plates and hollow semi-spheres, there is a certain gap between the rotating cylinder and the support rods, which can be designed according to actual situations. Affected by wind force at high altitude, the two hollow semi-spheres will be blown to rotate, and at the same time drive the rotating cylinder to rotate, so that the scraping plate scrapes the inner wall of the rotating cylinder. When rats and ants enter, they will be swept down, thereby reducing the possibility of rats and ants climbing up the submarine cable along the support rods to bite.

[0020] Referring to Figure 1-8 , the present invention proposes a special marine engineering power cable for preventing rats and ants, including a submarine cable 1 and a vertically arranged support rod 2, where:

[0021] The top end of the support rod 2 is connected with a positioning sleeve 3, the positioning sleeve 3 is sleeved on the submarine cable 1, a support frame 4 is sleeved on the support rod 2, the bottom end of the support frame 4 is rotatably connected with a rotating cylinder 5 sleeved on the support rod 2, and the outer wall of the rotating cylinder 5 is connected with a hollow semi-sphere 7; a plurality of scraping plates 6 for scraping the inner wall of the rotating cylinder 5 are circumferentially arranged on a section of the support rod 2 located inside the rotating cylinder 5.

[0022] The submarine cable 1 is generally installed at a high altitude. There is wind flow at high altitudes. When the wind flows, it will drive the two hollow semi-spheres 7 to rotate and drive the rotating cylinder 5 to rotate. When rats and ants climb into the rotating cylinder 5, they will be swept off by the scraping plates 6, reducing the rats and ants from climbing onto the submarine cable 1 and biting it; the length design of the scraping plates 6 makes it necessary for rats and ants to climb into the interior of the rotating cylinder 5 to continue climbing upward.

[0023] In a specific embodiment, the support rod 2 is circumferentially connected with a plurality of rotating seats 8, and the number of the plurality of rotating seats 8 is the same as and corresponds to the number of the plurality of scraping plates 6 one by one. Both ends of the rotating seat 8 are rotatably connected with one side of the scraping plate 6 close to the support rod 2 through a first rotating shaft, and torsion springs 9 are sleeved on both first rotating shafts; when an ant corpse gets stuck between the scraping plate 6 and the inner wall of the rotating cylinder 5, when the rotating cylinder 5 rotates, it will drive the scraping plate 6 to deflect, and at the same time, the scraping plate 6 swings under the action of the torsion spring 9 to bounce off the stuck ant corpse, which can reduce the occurrence of the situation where the rotating cylinder 5 is stuck.

[0024] In a specific embodiment, a scraping rod 10 for scraping the inner wall of the rotating cylinder 5 is connected to the bottom of the scraping plate 6; the width of the scraping rod 10 is smaller than the width of the scraping plate 6, and the bottom of the scraping rod 10 is flush with the bottom of the rotating cylinder 5; this can enable the scraping rod 10 to scrape the inner wall of the rotating cylinder 5 to ensure the scraping effect on the inner wall of the rotating cylinder 5.

[0025] In a specific embodiment, a plurality of rotating frames 11 are circumferentially connected to the support rod 2. A turning plate 12 is rotatably connected to the rotating frame 11. The bottom end of the turning plate 12 is rotatably connected to the rotating frame 11, and the rotation angle of the turning plate 12 is greater than 90 degrees. A reset assembly is installed on the support rod 2 to enable the turning plate 12 to rotate upward and be in a vertical state. When a mouse climbs onto the turning plate 12, affected by the pulling force of the mouse's scratching and the weight of the mouse itself, a plurality of turning plates 12 will turn and open like a flower, and the center of gravity of the mouse's body will become unstable. At the same time, when the turning plate 12 turns and opens, the mouse is in a state of weightlessness and will fall down.

[0026] In a specific embodiment, the reset assembly includes a reset ring 13 and a plurality of jacking springs 14. The reset ring 13 is slidably sleeved on the support rod 2. A plurality of anti - detachment sliders 15 are connected to the inner wall of the reset ring 13. A plurality of anti - detachment chutes that correspond one - to - one and are slidably matched are opened on the support rod 2. The plurality of jacking springs 14 are respectively located in the plurality of anti - detachment chutes, and the top ends of the jacking springs 14 are connected to the bottom ends of the anti - detachment sliders 15. The jacking springs 14 are always in a compressed state. A plurality of connecting rods 16 are circumferentially connected to the reset ring 13. The number of the connecting rods 16 is the same as and corresponds one - to - one with the number of the turning plates 12. The two ends of the connecting rods 16 are respectively rotatably connected to the reset ring 13 and the turning plate 12. It can be realized that a plurality of turning plates 12 can be opened simultaneously in a flower shape and can be turned and reset simultaneously. By the action of the plurality of jacking springs 14 to jack up the anti - detachment sliders 15, the reset ring 13 can be driven to reset, thereby driving the turning plate 12 to reset and can be reused.

[0027] In a specific embodiment, a plurality of rolling balls 17 that can roll on the outer wall of the support rod 2 are circumferentially connected to the inner wall of the reset ring 13. A plurality of anti - detachment movable grooves corresponding one - to - one with the plurality of rolling balls 17 are opened on the inner wall of the reset ring 13. It makes the sliding friction between the reset ring 13 and the support rod 2 be converted into rolling friction, reduces the frictional force, reduces the occurrence of jamming, so as to facilitate the smooth turning of the turning plate 12 and ensure that the mouse falls down.

[0028] The working principle of the present invention is as follows: the support rod 2 can be vertically installed on the ground, and then the positioning sleeve 3 can be installed on the submarine cable 1 to fix the position of the submarine cable 1 and support it. When a mouse climbs along the support rod 2, when the mouse climbs to the position of the flip plate 12, when the mouse's claws grab the flip plate 12, the flip plate 12 is flipped outward on the rotating frame 11 due to the gripping force of the mouse's claws and the weight of the mouse's body. As the flip plate 12 rotates and drives the connecting rod 16 to rotate and move downward, it will pull and pull the reset ring 13 down. When the reset ring 13 is descending, the other connecting rods 16 will move synchronously, so that all the flip plates 12 are flipped at the same time. The petal-shaped opening, as the flip plate 12 flips, the mouse's body will be unstable, and the mouse's claws will lose their fulcrum and fall down. After the mouse falls down, the flip plate 12 is not affected by external forces. Under the action of multiple lifting springs 14, multiple anti-dropping sliders 15 are lifted up at the same time to drive the reset ring 13 to slide up on the support rod 2. When the reset ring 13 rises, the ball 17 rolls on the outer wall of the support rod 2. When the reset ring 13 rises, it drives one end of the connecting rod 16 to rise. As the connecting rod 16 rises and rotates, the other end of the connecting rod 16 rotates on the flip plate 12 at the same time, driving the flip plate 12 to rotate upward and stand up.

[0029] When an ant climbs onto the support rod 2, when the ant climbs to the position of the rotating cylinder 5, due to a certain gap between the inner wall of the rotating cylinder 5 and the outer wall of the support rod 2, the ant cannot directly climb onto the rotating cylinder 5. The ant can only climb into the rotating cylinder 5 and climb onto the scraper 6, and then climb up the outer wall of the rotating cylinder 5 through the inner wall of the rotating cylinder 5. However, when the ant climbs to the inner wall of the rotating cylinder 5, the hollow semi-circular spheres 7 are blown to rotate under the action of high-altitude wind. When the two hollow semi-circular spheres 7 rotate, they will drive the rotating cylinder 5 to rotate. When the rotating cylinder 5 rotates, the scraper 6 will scrape the inner wall of the rotating cylinder 5, and sweep the ants climbing on the inner wall of the rotating cylinder 5 down, and at the same time, the scraper rod 10 will scrape the remaining inner wall of the rotating cylinder 5.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
