DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0027] Please refer to Figure 1-Figure 6 ,in, Figure 1 A schematic diagram of the overall structure of the distributed fault monitoring device provided by the utility model; Figure 2 A schematic diagram of a partial explosion structure provided by the utility model; Figure 3 A schematic diagram of the lower housing and its internal structure provided by the utility model; Figure 4 A schematic diagram of the connection position structure of the fixing frame provided by the utility model; Figure 5 Schematic diagram of the connection position structure of the engaging member provided by the present utility model; Figure 6 Schematic diagram of the fixing member provided by the present utility model.

[0028] In the specific implementation process, as Figure 1-Figure 6 shown, the distributed fault monitoring device includes an upper housing 1 and a lower housing 2. The upper housing 1 is movably connected to the lower housing 2. A detection probe 3 is arranged inside the lower housing 2, and the detection probe 3 is fixedly connected to the inside of the lower housing 2. A clamping groove 4 is arranged at the top end of one side of the detection probe 3, and a fixing frame 5 is arranged at the top of the detection probe 3; the top view of the fixing frame 5 is a "C" - shaped structure. The side of the fixing frame 5 away from the clamping groove 4 is hinged to the detection probe 3. Clamping members are fixedly connected to both ends of the side of the fixing frame 5 near the clamping groove 4, and the clamping members are adapted to the clamping groove 4. The clamping member includes a fixing block 6, a spring 7, and a clamping block 8. A fixing groove is opened at the bottom of the fixing block 6, the inner bottom surface of the fixing groove is fixedly connected to one end of the spring 7, and the other end of the spring 7 is fixedly connected to the clamping block 8. The clamping block 8 has a trapezoidal longitudinal section, and the slope structure of the clamping block 8 faces downward for easy installation. The longitudinal section of the clamping groove 4 is an "L" - shaped. When the upper housing 1 and the lower housing 2 are connected, a cylindrical pipe structure is formed. The contact surface between the upper housing 1 and the lower housing 2 is a structure that is obliquely cut from the outer wall of the pipe upward to the inner wall of the pipe. This obliquely cut contact surface creates a natural drainage channel. When rainwater contacts this inclined surface, it will flow away along the direction of the inclined surface instead of seeping in along the gap. This design effectively reduces the possibility of rainwater entering the interior of the pipe. A limiting post 9 is fixedly connected to the contact surface between the lower housing 2 and the upper housing 1, and a groove adapted to the limiting post 9 is arranged on the bottom surface of the upper housing 1. The setting of this structure can ensure the corresponding positions of the upper and lower housings 2. The top of the limiting post 9 is a hemispherical structure, and the setting of the hemispherical structure facilitates the splicing of the upper and lower housings 2. A sealing gasket is arranged on the contact surface between the upper housing 1 and the lower housing 2, and the setting of the sealing gasket further prevents rainwater from entering the interior of the housing. Connection rings 10 are welded to both ends of the upper housing 1 and the lower housing 2, and limiting rings 11 are welded to the free ends of multiple connection rings 10. A sealing ring is arranged inside multiple connection rings 10 and multiple limiting rings 11 to prevent rainwater from entering the interior of the housing from here. Fixing members are arranged outside multiple connection rings 10; the fixing member includes an upper ring body 12 and a lower ring body 13. One end of the upper ring body 12 is hinged to one end of the lower ring body 13, and the other end of the upper ring body 12 and the lower ring body 13 are connected by a bolt 14.

[0029] The working principle provided by the utility model is as follows: when maintenance and inspection are required, the bolts 14 are removed, the upper ring body 12 is separated from the lower ring body 13, the fixing parts are removed, the upper shell 1 is removed, and the lower shell 2 is still fixed on the cable by the setting of the fixing frame 5 and does not fall off. When there is no need to remove the lower shell 2, the lower shell 2 is rotated to inspect the cable. When the lower shell 2 needs to be removed, the locking block 8 is pressed, and the locking block 8 squeezes the spring 7 until the locking block 8 is retracted into the groove provided by the fixing block 6, the fixing frame 5 is turned over, the lower shell 2 is removed, and the cable is inspected.

[0030] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
