[0017] In the initial state, the collection unit body 1 and the hanging arm 2 are in Figure 1 and Figure 2 When the first screw 8 is rotated, the first slide 9 will be driven downward by the first slide 9, and the first slide 9 will press the first slide 10 to move downward, so that the first slide 9 will move downward. Figure 2As shown, the first slider 10 will move downward in the oblique slide groove provided inside the hanging arm 2. Under the action of the oblique slide groove, the first slider 10 will move downward and move to the side away from the first slide plate 9. The first slider 10 will drive the rack rod 7 to move through the first steel rope 11, and the rack rod 7 will drive the gear 6 to drive the collection unit body 1 to rotate until the collection unit body 1 and the hanging arm 2 are closed; then the first screw rod 8 stops rotating, and with the cooperation of the thread, the first slide plate 9 can remain stable after stopping moving; during the rotation of the collection unit body 1, the clamping plate 3 thereon can also be completely fitted with the cable under the action of the push plate 5 and the third steel rope 27; the two clamping plates 3 can wrap the cable to the maximum extent, which can greatly improve the clamping force, and at the same time can avoid the cable of the monitoring section from being overly exposed to the air, which can greatly reduce the impact of rain and snow on monitoring; when the recorder needs to be maintained, repaired or disassembled, the same staff only needs to rotate the first screw rod 8 in the opposite direction to make the collection unit body 1 rotate downward and open, and the staff can operate it with one hand, which can greatly reduce the difficulty of installing the recorder.

[0018] Specifically, Figure 3 , Figure 5 and Figure 6 As shown, a threaded hole 12 is provided on the wing plate 4 on the clamping plate 3 installed on the collection unit body 1, and a through hole 13 is provided on the wing plate 4 on the clamping plate 3 installed on the hanging arm 2 at a position corresponding to the threaded hole 12; a second screw 14 is provided above the through hole 13, and the second screw 14 can be screwed with the threaded hole 12; a second driving mechanism is installed inside the hanging arm 2, and the second driving mechanism can drive the second screw 14 to dock with the threaded hole 12; the second driving mechanism includes telescopic rods 15, the number of the telescopic rods 15 is the same as the number of the second screws 14, the bottom ends of the telescopic rods 15 are fixedly connected to the second screws 14 respectively, and the top ends of the telescopic rods 15 are rotatably connected to the hanging arm 2; the top end of the telescopic rod 15 is fixedly connected to a first sprocket 16; the bottom end of the first screw 8 is fixedly connected to a second sprocket 17; the first sprocket 16 and the second sprocket 17 are connected by a chain 18.

[0019] When the staff rotates the first screw 8 to close the collection unit body 1 and the hanging arm 2, and the clamping plate 3 is completely in contact with the cable, the wing plates 4 on both sides of the clamping plate 3 will be in a horizontal state; the wing plates 4 move to the upper and lower sides of the clamping plate 3 under the action of the push plate 5. Figure 5 and Figure 6 When the second screw 14 is in the position shown in FIG. 1 , the support force of the wing plate 4 on the second screw 14 disappears, and the second screw 14 is inserted into the through hole 13 under the action of gravity and moves to Figure 6The position shown; when the staff rotates the first screw 8 again, the telescopic rod 15 will be driven to rotate synchronously through the second sprocket 17, the chain 18 and the first sprocket 16, and the bottom end of the telescopic rod 15 will drive the second screw 14 to rotate synchronously, and under the action of the threaded hole 12, the second screw 14 will move downward; with the cooperation of the second screw 14 and the threaded hole 12, the clamping force of the two clamps 3 on the cable can be greatly improved, which can make the connection between the recorder and the cable more stable; when the recorder needs maintenance, repair or disassembly, when the staff rotates the first screw 8 in the opposite direction, the second screw 14 will move upward first, until it is disengaged from the threaded hole 12, the acquisition unit body 1 will be opened with the hanging arm 2, and after the staff removes the recorder, they only need to push the second screw 14 out of the through hole 13, and then the clamp 3 can be restored to its initial state.

[0020] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, a support block 19 is fixedly connected to the outer wall of the hanging arm 2, and a support rod 20 is slidably installed on the support block 19 in the vertical direction. The support rod 20 is set to be C-shaped, and a plurality of wedge-shaped limit blocks 21 equidistantly distributed are elastically slidably installed on the support block 19, and the wedge-shaped limit blocks 21 are used to limit the support rod 20.

[0021] When the staff hangs the hanging arm 2 on the cable, they can first push the hanging arm 2 so that the cable is in the C-shaped groove of the support rod 20, and then press the hanging arm 2 downward. When the hanging arm 2 moves downward relative to the cable, the cable will drive the support rod 20 to move upward on the support block 19; under the action of the wedge-shaped limit block 21, the support rod 20 can only move upward on the support block 19, and the support rod 20 can cooperate with the support block 19 to clamp the cable, which can prevent the hanging arm 2 suspended on the cable from falling off. The staff can safely turn the first screw 8 with one hand, which is more convenient for the staff to operate with one hand.

[0022] Specifically, Figure 4 As shown, a push rod 22 for pushing the wedge-shaped limit block 21 is slidably mounted on the support block 19 , and a second steel rope 23 is fixedly connected to the push rod 22 . The second steel rope 23 passes through the side wall of the hanging arm 2 at one end away from the push rod 22 and extends to the outside of the hanging arm 2 .

[0023] When the recorder needs to be disassembled, after loosening the first screw 8, the staff can pull the second steel rope 23 to make the push rod 22 push the wedge-shaped limit block 21 to move, and the wedge-shaped limit block 21 will cancel the limit on the support rod 20, and then the support rod 20 can return to the original position under the action of gravity. Figure 1 The position shown in the figure, and then the staff can pull out the hanging arm 2 horizontally to realize the disassembly of the recorder.

[0024] Specifically, Figure 4As shown, a pull plate 24 is fixedly connected to the outer end of the second steel rope 23 ; the pull plate 24 can facilitate the staff to pull the second steel rope 23 .

[0025] Specifically, Figure 4 As shown, the support rod 20 is composed of two fixed rods 25 and two movable rods 26 . The two fixed rods 25 are slidably connected to the support block 19 ; and the two movable rods 26 are rotatably connected to the fixed rods 25 .

[0026] Although the support rod 20 can support the cable, the cable will shake in abnormal weather, such as strong winds and heavy rain. The movable rod 26 can swing with the cable, and the cable is in soft contact with the support rod 20 when shaking, which can reduce damage to the cable.
