A hinge is arranged on one side of the upper casing and the lower casing, and a fastening device is arranged on the other side of the upper casing and the lower casing.

[0006] Preferably, the fastening device includes a fixing rod arranged on the upper casing and a locking device arranged on the lower casing.

[0007] Preferably, the locking device includes a locking rod, a driving block, a spring, and an eccentric rotating cylinder.

[0008] Preferably, the locking rod is a U-shaped groove structure, and a strip-shaped through hole is formed in its side wall.

[0009] Preferably, the strip-shaped through hole is inclined inward.

[0010] Preferably, a protruding slide bar is provided on the driving block, and a groove is provided at one end of the driving block.

[0011] Preferably, a support column is provided on the lower housing corresponding to the opening of the groove.

[0032] After the lower housing 2 is installed on the transmission line, the upper housing 1 is then connected to the lower housing 2 through the hinge 3, and after closing, the upper housing 1 and the lower housing 2 are closed through the fastening device 4.

[0033] Refer to Figure 3-4 As shown, the fastening device 4 includes a fixing rod 5 provided on the upper housing 1 and a locking device 6 provided on the lower housing 2.

[0034] A through hole 23 is provided on the upper side wall of the lower housing 2. The fixing rod 5 is inserted into the lower object 2 through the through hole 23, and the movement of the fixing rod 5 is restricted by the locking device 6.

[0035] Preferably, the locking device 6 includes a locking rod 61, a driving block 62, a spring 63, and an eccentric rotating cylinder 64.

[0036] A limit card slot 51 is provided on the fixing rod 5, and a limit card block 612 is provided on the locking rod 61.

[0037] The fixing rod 5 is inserted into the lower object 2 through the through hole 23, and the limit card block 612 on the locking rod 61 is inserted into the limit card slot 51 on the fixing rod 5 to limit the fixing rod 5, thereby realizing the locking of the upper housing 1 and the lower housing 2.

[0038] Refer to Figure 4 As shown, the locking rod 61 has a U-shaped groove structure. One end of the locking rod 61 is rotatably connected to the upper side wall of the lower housing 2 through a rotating structure 25. The rotating structure 25 is a prior art, such as a hinge mechanism, etc., and will not be elaborated.

[0039] A groove 622 is provided at one end of the driving block 62, and a support column 21 is provided on the lower housing 2 corresponding to the opening of the groove 622; one end of the spring 63 is inserted into the groove 622, and the other end is sleeved on the support column 21. The support column 21 prevents the end position of the spring from shifting during the extrusion deformation process and the bending of the spring 63 body.

[0040] The driving block 62 slides in the U-shaped groove of the locking rod 61 under the action of the spring 63.

[0041] An inwardly inclined strip-shaped through hole 611 is provided on the side wall of the U-shaped groove of the locking rod 61, and a protruding sliding rod 621 is provided on the driving block 62; when the driving block 62 slides in the U-shaped groove of the locking rod 61 under the action of the spring 63, the sliding rod 621 slides in the strip-shaped through hole 611, driving the locking rod 61 to rotate around the rotating structure 25, so as to realize the insertion of the limit card block 612 on the locking rod 61 into the limit card slot 51 on the fixing rod 5.

[0042] An opening 24 is provided on the outer side wall of the lower housing 2. A support plate 22 is fixedly arranged inside the lower housing 2. The upper and lower ends of the support plate 22 are respectively fixedly welded to the upper side wall and the bottom side wall of the lower housing 2. Sealing plates are connected to both sides of the support plate 22, and the edges of the sealing plates are welded and sealed along the edge of the opening 24, so that the cavity where the locking device 6 is installed is an independent cavity.

[0043] The support plate 22 is fixedly provided with a rotating shaft 221, and the eccentric rotating cylinder 64 rotates around the rotating shaft 221.

[0044] Holes are provided on the eccentric rotating cylinder 64. By inserting a straight rod into the holes to rotate the eccentric rotating cylinder 64, the eccentric rotating cylinder 64 rotates and squeezes to drive the sliding of the driving block 62, driving the locking rod 61 to rotate around the rotating structure 25, so that the limiting block 612 on the locking rod 61 withdraws from the limiting slot 51 on the fixing rod 5.

[0045] In summary, the beneficial effects of the present utility model include providing an intelligent detection and early warning device for faults in the collector line of a wind farm, with a simple structure, effectively fastening and connecting the upper and lower housings, thus solving the problem of loosening of the threaded structure caused by vibration.
