[0026] Embodiment 1

[0027] A power transmission line disconnection warning detection system across residential agglomerations, as Figures 1-4 shown, includes: an anti-drop mechanism, which is used to prevent the conductor 3 from falling and avoid the harm caused by disconnection. The anti-drop mechanism includes a connecting clamp 5 and at least one extension rod 6. The connecting clamp 5 includes a housing 19, and a first clamp 22 and a second clamp 23 are detachably arranged in the housing 19, and a receiving space 24 for receiving the conductor 3 is formed between the first clamp 22 and the second clamp 23. The first clamp 22 and the second clamp 23 fix the conductor 3 in the receiving space 24. One end of the extension rod 6 is rotatably connected to the housing 19 to facilitate adjusting the rotation angle of the extension rod 6. The other end of the extension rod 6 is connected to the DB adjustment plate for connecting the conductor 3 and the tower. Rotate the extension rod 6 to a suitable position. When the conductor 3 drops, the extension rod 6 pulls the connecting clamp 5 to prevent the conductor 3 from completely falling.

[0028] The DB adjustment plate is connected to the insulator string 4 on the tower. The DB adjustment plate includes a main adjustment plate 1 and at least one sub-adjustment plate 2. The main adjustment plate 1 is connected to the insulator string 4 through a lining plate, and all the sub-adjustment plates 2 are connected to the main adjustment plate 1 to ensure the flexibility of adjusting the tension of the conductor 3 and the distance between the extension rod 6 and the conductor 3. Therefore, a dovetail groove 28 is formed at the edge of the main adjustment plate 1, and a plurality of dovetail blocks 30 matching the dovetail groove 28 are slidably arranged in the dovetail groove 28. The dovetail blocks 30 are connected to the sub-adjustment plates 2 one by one. According to actual needs, slide the dovetail blocks 30 to suitable positions in the dovetail groove 28 and connect an appropriate number of sub-adjustment plates 2. The sub-adjustment plates 2 are connected to the conductors 3 of the power transmission line one by one through strain clamps 14. The strain clamps 14 and the sub-adjustment plates 2 are connected through connecting plates 15. The strain clamps 14 are conventional prior art in the art. The specific structure, model and how to connect to the conductor 3 of the strain clamps 14 will not be elaborated too much here. In addition to the dovetail groove 28 being formed on the main adjustment plate 1, dovetail grooves 28 can also be formed on the sub-adjustment plates 2.

[0029] To facilitate the connection between the dovetail block 30 and the secondary adjustment plate 2, a connection block 31 is fixedly arranged on the dovetail block 30, and the dovetail block 30 extends out of the dovetail groove 28. The connection block 31 is connected to the secondary adjustment plate 2 one by one through a connecting piece, which is a conventional prior art in this field and will not be elaborated here. To prevent the dovetail block 30 from falling off when sliding in the dovetail groove 28, a blocking bolt 29 is inserted through the main adjustment plate 1, and the blocking bolt 29 is located at the inlet of the dovetail groove 28. To fix the dovetail block 30 at an appropriate position, a stop rod 32 is fixedly arranged on the dovetail block 30. When the dovetail block 30 is located in the dovetail groove 28, the stop rod 32 is connected to the surface of the main adjustment plate 1, and a fastening bolt 33 is inserted through the dovetail block 30. The fastening bolt 33 can press the dovetail block 30 against the inner wall of the dovetail groove 28.

[0030] The induction mechanism includes a controller, which is electrically connected to a tensile force sensor 9 and a Beidou positioning module for obtaining the position of the wire 3. The extension rod 6 is connected to the DB adjustment plate through the tensile force sensor 9, and the tensile force sensor 9 is used to obtain the tensile force data of the extension rod 6. Once the wire 3 breaks, the tensile force sensor 9 is subjected to a tensile force. The controller judges that a break has occurred according to the data change of the tensile force sensor 9, and then knows the break position according to the Beidou positioning module to give an alarm, so that the operator can timely judge the break position for remedy.

[0031] The above is the basic implementation mode of the present invention, and further improvements, optimizations and limitations can be made on this basis to obtain the following embodiments:

[0032] Embodiment 2

In this way, under the premise of ensuring that the extension rod 6 can rotate, the relative position between the housing 19 and the extension rod 6 can be adjusted to a certain extent, further increasing the flexibility of the use of the extension rod 6. The other ends of the two extension rods 6 are connected by a connecting shaft, and the part of the connecting shaft extending out of the extension rod 6 is connected to the tension sensor 9. The connection between the tension sensor 9 and the connecting shaft is a conventional prior art in the field, and no more details are given here. The tension sensor 9 is connected to the DB adjustment plate through an adjustment component 10, and the adjustment component 10 includes a connecting ring 11, and two coaxially arranged and oppositely threaded adjustment screws 12 are passed through the connecting ring 11, one of which is connected to the connecting shaft, and the other is connected to the DB adjustment plate. When the distance between the extension rod 6 and the DB adjustment plate needs to be adjusted, the connection ring 11 is rotated so that the two first adjustment bolts are moved closer or farther away from each other at the same time, and the distance between the extension rod 6 and the wire 3 can also be adjusted.

[0034] Example 3

[0035] This embodiment is an improved solution based on the embodiment 1, and its main structure is the same as that of the embodiment 1, and the improvement lies in that: a channel is provided through the housing 19, and the channel gradually narrows in the direction away from the DB adjustment plate, and the first clamp 22 and the second clamp 23 are both adapted to the shape of the channel, and the first clamp 22 and the second clamp 23 are inserted from the end with a larger diameter of the channel, so that when the wire 3 is connected to the DB adjustment plate through the connecting wire clamp 5, the first clamp 22 and the second clamp 23 will be subjected to the tension of the wire 3, and the direction of this tension is in the direction away from the DB adjustment plate, which can make the first clamp 22, the second clamp 23 and the housing 19 more tightly matched. The part of the first clamp 22 close to the DB adjustment plate and the part of the second clamp 23 close to the DB adjustment plate are connected by fixing bolts 27, which further ensures the fixation of the wire 3.

[0036] Example 4

[0037] This embodiment is an improved solution based on Embodiment 3. Its main structure is the same as that of Embodiment 3. The improvement lies in that in order to facilitate the connection between the first clip 22 and the second clip 23, both the first clip 22 and the second clip 23 are fixedly connected with a connecting portion 26, and the two connecting portions 26 both extend out of the housing 19. The two connecting portions 26 are connected by the fixing bolt 27. The first clip 22 is fixedly connected with a plug rod 13, and the second clip 23 is provided with a jack for the plug rod 13 to pass through. The plug rod 13 is arranged in a long strip shape, and the jack is matched with the plug rod 13. The plug rod 13 is inserted into the jack to prevent the first clip 22 and the second clip 23 from twisting when the fixing bolt 27 is tightened.

A baffle 16 and a guide plate 18 are connected to the extension plate 17. The baffle 16 contacts the outer surface of the housing 19, and the guide plate 18 contacts the inner wall of the housing 19 and the surface of the first clip 22. The extension plate 17, the baffle 16 and the guide plate 18 are integrally connected, which is convenient for the splicing between the housing 19, the extension plate 17, the baffle 16 and the guide plate 18. The diameter of the opening is smaller than the width of the guide plate 18 to prevent the guide plate 18 from falling off from the opening. A plurality of sliding grooves are provided on the baffle 16, and the housing 19 is provided with ridges 20 corresponding to the sliding grooves. When pressure is applied to the baffle 16 or the housing 19, the ridges 20 can play a role in dispersing the pressure to a certain extent.

[0040] Embodiment 6
