Description

Technical Field

[0001] This utility model relates to the field of electronic fence technology, specifically to an electronic fence. Background Technology

[0002] Electronic fences, as active intrusion detection and alarm devices, are widely used for perimeter protection in photovoltaic power plants, factory parks, substations, and other locations. They form a protective net using wires, which, in conjunction with an alarm system, effectively blocks illegal intrusion and provides timely warnings, ensuring area security. However, current electronic fences on the market suffer from numerous compatibility and operational deficiencies during actual installation and use, making it difficult to meet the protection needs of complex scenarios. Traditional electronic fences typically use an integrated wire fixing structure or are fixed to specific positions on the posts with bolts. This makes it impossible to flexibly adjust the wire spacing according to protection needs. If the wire density needs to be adjusted for different scenarios (such as preventing people from climbing or blocking small animals from entering), the original fixing structure must be disassembled and new holes drilled for installation. This process is cumbersome and can easily damage the posts. In addition, existing electronic fence posts are mostly vertically fixed installation structures, which cannot adjust the tilt angle and are difficult to adapt to diverse protection needs.

[0003] To address the aforementioned issues, there is an urgent need for innovative designs based on existing electronic fences. Utility Model Content

[0004] To address the existing technical problems of the inability to flexibly adjust the wire spacing according to protection needs and the inability to adjust the tilt angle of the electronic fence posts, this utility model provides an electronic fence.

[0005] This utility model is achieved using the following technical solution: an electronic fence, comprising a base and a post, wherein a first fixing plate and a second fixing plate are fixedly connected to the top of the base, the post is rotatably connected between the first fixing plate and the second fixing plate, a fixing ring is movably connected to the outside of the post, a wire-locking groove is fixedly connected to one end of the fixing ring, a locking bolt is provided at the other end of the fixing ring, one end of the locking bolt is threadedly connected to the inside of the fixing ring, and one end of the locking bolt is in contact with the outside of the post; The first fixed plate has a rotating shaft fixedly connected to its inner side. A rotating groove is machined on one side of the bottom of the column. The rotating shaft is rotatably connected to the inside of the rotating groove. A fixed toothed groove is machined inside the rotating shaft. A movable toothed groove is machined at one end of the rotating groove. A handwheel is provided on the outer side of the first fixed plate. A connecting rod is fixedly connected to the inner side of the handwheel. A limiting toothed ring is fixedly connected to one end of the connecting rod. The connecting rod is rotatably connected to the inside of the first fixed plate. One end of the limiting toothed ring is inserted into the inside of the fixed toothed groove. The limiting toothed ring is movably connected to the inside of the movable toothed groove.

[0006] Preferably, a groove is machined on one side of the column, and a slider is fixedly connected to the inner side of the fixing ring, with the slider being movably connected inside the groove.

[0007] Preferably, a connecting shaft is fixedly connected to one side of the bottom of the column, and the connecting shaft is rotatably connected inside the second fixed plate.

[0008] Preferably, one end of the movable tooth groove is machined with a spring cavity, and a return spring is provided inside the spring cavity. One end of the return spring is fixedly connected to the inner wall of one end of the spring cavity, and the other end of the return spring is fixedly connected to a push plate.

[0009] Preferably, the push plate is movably connected inside the movable tooth groove, and one side of the push plate is in contact with one side of the limiting tooth ring.

[0010] Preferably, when the limiting toothed ring is completely inside the movable toothed groove, the limiting toothed ring will disengage from the fixed toothed groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In use, pushing the handwheel inward causes the connecting rod to move, which in turn moves the limiting toothed ring. This causes the limiting toothed ring to disengage from the fixed toothed groove and become fully positioned within the movable toothed groove, thus releasing the fixed connection between the rotating shaft and the column. Rotating the handwheel then causes the connecting rod and the limiting toothed ring to rotate, which in turn causes the column to rotate via the movable toothed groove, adjusting the column to a suitable tilt angle. The entire operation requires no complex tools, is simple and efficient, and can be flexibly adapted to various application scenarios such as slopes, corners, and irregular boundaries, improving the installation adaptability of the electronic fence.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0015] Example 1: Please refer to Figure 1 - Figure 4 An electronic fence according to this embodiment includes a base 1 and a post 2. A first fixing plate 4 and a second fixing plate 12 are fixedly connected to the top of the base 1. The post 2 is rotatably connected between the first fixing plate 4 and the second fixing plate 12. A fixing ring 3 is movably connected to the outside of the post 2. One end of the fixing ring 3 is fixedly connected to a wire-locking groove 5, and the other end of the fixing ring 3 is provided with a locking bolt 6. One end of the locking bolt 6 is threaded into the inside of the fixing ring 3, and the other end of the locking bolt 6 is in contact with the outside of the post 2. A rotating shaft 9 is fixedly connected to the inner side of the first fixing plate 4. A rotating groove 10 is machined on one side of the bottom of the 2. A rotating shaft 9 is rotatably connected to the inside of the rotating groove 10. A fixed toothed groove 16 is machined inside the rotating shaft 9. A movable toothed groove 17 is machined at one end of the rotating groove 10. A handwheel 13 is provided on the outside of the first fixed plate 4. A connecting rod 14 is fixedly connected to the inside of the handwheel 13. A limiting toothed ring 15 is fixedly connected to one end of the connecting rod 14. The connecting rod 14 is rotatably connected to the inside of the first fixed plate 4. One end of the limiting toothed ring 15 is inserted into the inside of the fixed toothed groove 16. The limiting toothed ring 15 is movably connected to the inside of the movable toothed groove 17. When it is necessary to adjust the distance between the fixed rings 3, the locking bolts 6 are loosened, and the fixed rings 3 are moved up and down. When the fixed rings 3 are moved to the appropriate position, the locking bolts 6 are tightened so that the locking bolts 6 contact the outside of the column 2, thereby locking the fixed rings 3. Then the wires are inserted into the wire clamping groove 5 and clamped. The wire clamping grooves 5 of multiple columns 2 form an electronic fence, which controls the distance between the fixed rings 3 and the wires, and flexibly adapts to protection needs of different densities. Secondly, when it is necessary to adjust the tilt angle of the column 2, push the handwheel 13 inward. The handwheel 13 will drive the connecting rod 14 to move, and the connecting rod 14 will drive the limiting tooth ring 15 to move, so that the limiting tooth ring 15 is disengaged from the inside of the fixed tooth groove 16. The limiting tooth ring 15 will be completely located inside the movable tooth groove 17, thereby releasing the fixed connection between the rotating shaft 9 and the column 2. Then rotate the handwheel 13, and the handwheel 13 will drive the connecting rod 14 and the limiting tooth ring 15 to rotate. The limiting tooth ring 15 will drive the column 2 to rotate through the movable tooth groove 17, so that the column 2 is adjusted to a suitable tilt angle. The whole operation does not require complicated tools, the steps are simple and efficient, and it can flexibly adapt to various application scenarios such as slopes, corners, and irregular boundaries, improving the installation adaptability of the electronic fence. After the angle of column 2 is adjusted, one end of the movable limiting toothed ring 15 enters the interior of the fixed toothed groove 16, while the other end of the limiting toothed ring 15 remains inside the movable toothed groove 17. Thus, the column 2 is limited and fixed by the fixed toothed groove 16 and the movable toothed groove 17 to prevent the column 2 from rotating. Furthermore, a groove 8 is machined on one side of the column 2, and a slider 7 is fixedly connected to the inner side of the fixing ring 3. The slider 7 is movably connected inside the groove 8. When the fixing ring 3 moves up and down, the fixing ring 3 will drive the slider 7 to move. The slider 7 will move along the inside of the groove 8, and the groove 8 will limit the movement of the column 2 through the slider 7. Furthermore, a connecting shaft 11 is fixedly connected to one side of the bottom of the column 2. The connecting shaft 11 is rotatably connected to the inside of the second fixed plate 12. When the limiting toothed ring 15 drives the column 2 to rotate through the movable toothed groove 17, the rotating shaft 9 on one side of the first fixed plate 4 will rotate along the inside of the rotating groove 10, and the connecting shaft 11 on one side of the column 2 will rotate along the inside of the second fixed plate 12. Furthermore, a spring cavity 18 is machined at one end of the movable tooth groove 17, and a return spring 20 is provided inside the spring cavity 18. One end of the return spring 20 is fixedly connected to the inner wall of one end of the spring cavity 18, and the other end of the return spring 20 is fixedly connected to a push plate 19. The push plate 19 is movably connected inside the movable tooth groove 17, and one side of the push plate 19 is in contact with one side of the limiting tooth ring 15. The mechanism includes a return spring 20. When the handwheel 13 is pushed, it will drive the connecting rod 14 and the limiting tooth ring 15 to move. The limiting tooth ring 15 will push the push plate 19 to move, and the push plate 19 will squeeze the return spring 20. The return spring 20 will be compressed. When the handwheel 13 is released, the return spring 20 will return to its original position and extend. The return spring 20 will drive the push plate 19 to move along the inside of the movable tooth groove 17, thereby pushing the limit tooth ring 15 to insert into the inside of the fixed tooth groove 16.

[0016] Working principle: By loosening the locking bolt 6, the fixing ring 3 can be moved up and down. When the fixing ring 3 moves to the appropriate position, the locking bolt 6 is tightened so that it contacts the outside of the post 2, thereby locking the fixing ring 3. Then, the wire is inserted into the wire clamping groove 5 and locked in place. By pushing the handwheel 13 inward, the handwheel 13 will drive the connecting rod 14 to move. The connecting rod 14 will drive the limiting tooth ring 15 to move, causing the limiting tooth ring 15 to disengage from the fixed tooth groove 16. The limiting tooth ring 15 will then be completely located inside the movable tooth groove 17, thereby releasing the fixed connection between the rotating shaft 9 and the post 2. Then, the handwheel 13 is rotated, which will drive the connecting rod 14 and the limiting tooth ring 15 to rotate. The limiting tooth ring 15 will drive the post 2 to rotate through the movable tooth groove 17, adjusting the post 2 to a suitable tilt angle. This makes operation more convenient and improves the installation adaptability of the electronic fence.
