[0028] The present invention will be further described in detail below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings.

[0029] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] As Figures 1-4 shown, a rat-proof baffle for a distribution network overhead line includes a first baffle 1 and at least one second baffle 2 connected in series in sequence; a detachable sliding connection structure is provided between the first baffle 1 and the second baffle 2 and between adjacent second baffles 2, so that the second baffle 2 can slide along the length direction of the rat-proof baffle; both the first baffle 1 and the second baffle 2 are provided with a first notch 4 for passing a wire; a third baffle 3 is slidably connected to each of the first baffle 1 and each second baffle 2, the third baffle 3 is used to open or close the first notch 4, and a locking portion 5 for clamping the wire is provided on one side of the third baffle 3 facing the first notch 4.

[0031] With the above structure, the first baffle 1 and the second baffle 2 and between adjacent second baffles 2 are all detachably connected, which is a segmented and spliceable structure. The number of the second baffles 2 can be flexibly determined according to the number of distribution network lines, modularizing the baffles. According to different numbers of wire strands, such as two-phase lines, three-phase lines, three-phase four-wire lines, three-phase five-wire lines, etc., the number of the second baffles 2 can be adjusted, and it can be applied to different operating sections, with more flexible application; the second baffle 2 is slidably connected. By sliding the second baffle 2, the distance between the first baffle 1 and the second baffle 2 and between adjacent second baffles 2 can be adjusted, so as to adapt to the working conditions with different phase distances between wires, eliminate the influence of the change factor of the wire spacing, and increase the applicable range.

[0032] It can be imagined that the length of the first blocking portion 11 of the first baffle 1 is longer than that of the first connecting portion 12. Here, the length refers to the distance from the first notch 4 of the first baffle 1 to the short side of the first blocking portion 11, which blocks rats from climbing or jumping.

[0033] In one embodiment, as Figure 2 、 Figure 3 shown, the first baffle 1 includes a first blocking portion 11 connected to the third baffle 3 and a first connecting portion 12 connected to the second baffle 2. The first notch 4 of the first baffle 1 is opened on the first blocking portion 11; the second baffle 2 includes a second blocking portion 21 connected to the third baffle 3 and a second connecting portion 22 connected to the adjacent second baffle 2. The first notch 4 of the second baffle 2 is opened on the second blocking portion 21. The first notch 4 is opened on the first blocking portion 11 or the second blocking portion 21, so that the second baffle 2 will not block the first notch 4 during the sliding process.

[0034] In a further solution, the surface of the first baffle 1 facing the third baffle 3 is a stepped surface, and the first blocking portion 11 is higher than the first connecting portion 12; and / or the surface of the second baffle 2 facing the third baffle 3 is a stepped surface, and the second blocking portion 21 is higher than the second connecting portion 22.

[0035] In a specific connection method, adjacent baffles are connected by positive and negative buckling. For example, when the first baffle 1 is connected to the second baffle 2, the front surface of the first connecting portion 12 abuts against the back surface of the second blocking portion 21. When two second baffles 2 are connected, the front surface of the second connecting portion 22 abuts against the back surface of the second blocking portion 21. Here, the front surface refers to the convex surface of the arc-shaped baffle, and the back surface refers to the concave surface of the arc-shaped baffle.

[0036] When the baffles are connected by positive and negative buckling, setting a stepped surface can make the convex surface of the rat-proof baffle more flat and effectively increase the climbing difficulty of rats.

[0037] In a further solution, at least one first long sliding groove 13 is provided on the first connecting portion 12 of the first baffle 1, and at least one second long sliding groove 23 is provided on the second connecting portion 22 of the second baffle 2. The extending directions of the first long sliding groove 13 and the second long sliding groove 23 are parallel to the long side of the rat-proof baffle. The second blocking portion 21 of the second baffle 2 is provided with a second buckle 24 matching the first long sliding groove 13 or the second long sliding groove 23.

[0038] In a further solution, at least one third long sliding groove 31 is provided on the third baffle 3. The extending direction of the third long sliding groove 31 is parallel to the long side of the rat-proof baffle. First buckles 6 matching the third long sliding groove 31 are provided on both the first blocking portion 11 of the first baffle 1 and the second blocking portion 21 of the second baffle 2.

[0039] The first long sliding groove 13, the second long sliding groove 23, and the third long sliding groove 31 are parallel to each other and each is provided with at least two. Each long sliding groove is provided with a matching buckle. The buckle is buckled in the long sliding groove, and the buckle and the long sliding groove can slide relative to each other. With this structure, under the action of an external force, the second baffle 2 can be slid to adjust the distance between adjacent first gaps 4, so as to adapt to working conditions with different wire phase spacings; by sliding the third baffle 3, the first gap 4 can be opened, the wire can be inserted, and then the third baffle 3 is slid to close the first gap 4, so that the locking portion 5 locks the wire to complete the installation; the operation and installation are very simple. After being spliced and combined into a whole component, it can be put into use without any installation accessories and without tool operation.

[0040] Of course, in addition to this, structures such as anchor pins and screws can also be used for fixation.

[0041] In one embodiment, the first baffle 1, the second baffle 2, and the third baffle 3 are all arc-shaped, so that the short side of the rat-proof baffle is arc-shaped, that is, the long side of the rat-proof baffle is straight. The use of arc-shaped baffles has the following advantages: pure flat baffles are complex and difficult to process, and slight structural deformation may lead to inability to install; while the arc-shaped structure has higher strength, less deformation, and a more stable and reliable structure; at the same time, the arc-shaped baffle can effectively reduce wind resistance pressure and reduce shaking.

[0042] Of course, in addition to this, a flat baffle may also be used.

[0043] In one embodiment, the first notch 4 is U-shaped, the first notch 4 is inclined, and the opening end of the first notch 4 is the lower end; the inclined first notch 4 can prevent the wire from sliding out under the action of gravity, and is particularly suitable for lines arranged in vertical lines. At this time, the rat-proof baffle is naturally hung on the wire under the action of gravity, and the first baffle 1 is located at the top. Its higher height can effectively prevent mice from climbing or jumping over.

[0044] Of course, the above-mentioned rat-proof baffle can also be applied to horizontally arranged or obliquely arranged lines. It only needs to adjust the angle of the first notch 4 and the width of the rat-proof baffle so that it can be hung on the wire and prevent mice from climbing or jumping over.

[0045] In one embodiment, if Figure 4 As shown, the locking portion 5 includes an inner ring body 51, an outer ring body 52 and a guide body 53; the diameter of the inner ring body 51 is smaller than the diameter of the outer ring body 52, the inner ring body 51 is concentrically fixed in the outer ring body 52, and a plurality of connecting parts 54 are provided between the inner ring body 51 and the outer ring body 52 for connection; the guide body 53 is integrally connected to the outer ring body 52, and a guide channel 55 with a larger outer side and a smaller inner side is provided in the middle of the guide body 53, the larger end of the guide channel 55 faces the first notch 4 and is used for passing the wiring, and the smaller end passes through the inner ring body 51.

[0046] The guide body 53 has two opposite inclined surfaces, which play a guiding role and effectively prevent the wire from being stuck.

[0047] The locking portion 5 is made of elastic materials such as PC and ABS. When the diameter of the wire is large, the locking portion 5 will stretch to adapt to wires of different sizes. At the same time, when the size of the wire is too large, the connecting piece 54 between the inner ring body 51 and the outer ring body 52 can be broken off to allow the wire to be inserted into the outer ring body 52, further increasing the wire size adaptation range of the baffle, making the application more flexible and extensive.

[0048] Here, a breakpoint elastic design is adopted between the inner ring body 51 and the outer ring body 52, that is, a plurality of connecting members 54 are arranged at intervals, which can play a supporting role and can also be broken by external force.

[0049] In a further solution, a second notch 32 is formed on the side of the third baffle 3 facing the first notch 4. The outer ring body 52 of the locking portion 5 is correspondingly arranged in the second notch 32, and there is a gap for accommodating the elastic deformation of the locking portion 5 between the second notch 32 and the locking portion 5.

[0050] It can be conceived that the locking portion 5 can be fixed to the bottom of the second notch 32, and there is sufficient deformation gap between the two sides and the side walls of the second notch 32. In addition, the locking portion 5 can also protrude from the convex panel body of the third baffle 3 and be located above the second notch 32. When the locking portion 5 passes through the wire, the guiding body 53 and the outer ring body 52 will expand outwards. Since the locking portion 5 protrudes from the convex surface of the third baffle 3, there will be no interference between the guiding body 53 and the outer ring body 52 and the inner wall of the second notch 32 when they expand outwards. The second notch 32 can adopt a U-shaped groove, and its opening is aligned with the bottom of the first notch 4.

[0051] In order to increase the volume of the guiding body 53 and improve the stability of wire clamping, the thickness of the locking portion 5 can be increased so that the locking portion 5 protrudes from the convex surface of the anti-rat plate. The locking portion 5 can also be connected to the third baffle 3 through a fixing member. The fixing member has a certain height so that the locking portion 5 floats above the third baffle 3, thereby reducing the gap and also reducing the processing difficulty.

[0052] In one implementation, a pull ring 33 is provided on the third baffle 3, which is convenient for pulling the third baffle 3 to slide, and installation can be achieved without the aid of external tools.
