[0030] The following is combined with Figure 1-Figure 6 The utility model is described in further detail.

[0031] See also Figure 1-Figure 6 , the utility model provides an embodiment of a vehicle-mounted ultrasonic detection device for the partial discharge state of an insulator of a contact network: a vehicle-mounted ultrasonic detection device for the partial discharge state of an insulator of a contact network, comprising a fixing frame 1, side detection plates 2 are arranged at both ends of the fixing frame 1, the side detection plates 2 are used for ultrasonic detection, an upper detection plate 3 is arranged at the top of the fixing frame 1, and the upper detection plate 3 is used for ultrasonic detection; a connecting mechanism 4, the connecting mechanism 4 is arranged at both ends and the top of the fixing frame 1, and the connecting mechanism 4 extends to the inside of the fixing frame 1, the connecting mechanism 4 is used for conveniently connecting and disassembling the fixing frame 1, the upper detection plate 3 and the fixing frame 1, the side detection plate 2, the connecting mechanism 4 includes a clamping block 401 sleeved inside the fixing frame 1, and clamping grooves 201 are opened on both sides of the side detection plate 2, the clamping grooves 201 match the clamping block 401, and the setting of the clamping block 401 and the clamping groove 201 facilitates the rapid clamping of the side detection plate 2 and the fixing frame 1.

[0032] It can be further explained that, by setting the clamping block 401 and the clamping slot 201, it is convenient to quickly connect the side detection plate 2 and the fixing frame 1, and the fixing frame 1 and the upper detection plate 3. Compared with the method of fixing with multiple bolts, the connection time of the fixing frame 1 and the side detection plate 2 is reduced. At the same time, when inspecting the inside of the fixing frame 1, the disassembly time of the fixing frame 1 and the side detection plate 2 is reduced, thereby facilitating the inspection or replacement of the electronic components inside the fixing frame 1.

[0033] See also Figure 3 and Figure 6The connecting mechanism 4 also includes a moving box 402 sleeved on one side of the card block 401, and a moving groove matching the moving trajectory of the card block 401 is arranged inside the moving box 402. One side of the card block 401 is arranged in an inclined plane shape. The moving box 402 is used to limit the card block 401 and prevent the card block 401 from being separated from the fixed frame 1; a first spring 4011 is fixedly connected to one side of the card block 401, and the other side of the first spring 4011 is fixedly connected to the inner wall of the moving box 402, and the first spring 4011 is used to provide a horizontal movement reset force for the card block 401; a rack 403 is fixed to the bottom end of the moving box 402 by bolts, and the rack 403 is "L" shaped. A limiting groove 101 is provided on the inner wall of the fixed frame 1, and the limiting groove 101 matches the moving trajectory of the rack 403. The horizontal movement of the rack 403 can drive the moving box 402 to move, thereby driving the card block 401 to move horizontally, so as to facilitate the separation of the card block 401 from the card slot 201.

[0034] It can be further explained that the movement of the side detection plate 2 drives the card slot 201 to move, the outer wall of the side detection plate 2 squeezes one side of the card block 401, and squeezes the card block 401 to move toward the inside of the mobile box 402, and the first spring 4011 is squeezed. When the card slot 201 moves to one side of the card block 401, the first spring 4011 returns to its original state and drives the card block 401 to reset and move. The card block 401 resets and moves and engages with the card slot 201. At this time, the side detection plate 2 is connected and fixed to the fixing frame 1, and similarly, the fixing frame 1 and the upper detection plate 3 are connected and fixed.

[0035] See also Figure 5 and Figure 6 , the top of the rack 403 is meshed with a spur gear 404, the top of the spur gear 404 is meshed with another rack 403, one end of the spur gear 404 is welded with a rotating rod 405, the rotating rod 405 extends to the outside of the fixed frame 1, and the rotating rod 405 is rotatably connected to the inner wall of the fixed frame 1 through a bearing, and the end of the spur gear 404 away from the rotating rod 405 is welded with a connecting column, the connecting column is rotatably connected to the inner wall of the fixed frame 1 through a bearing, and the rotating rod 405 can drive the two racks 403 to move away from each other through mechanical transmission when the rotating rod 405 rotates clockwise; The interior of the rack 403 is sleeved with a limiting column 4031, and both sides of the limiting column 4031 are fixedly connected to the inner wall of the fixing frame 1 by bolts. The limiting column 4031 is used to support the rack 403, thereby ensuring the stability of the horizontal movement of the rack 403; one side of the rack 403 is fixedly connected with a second spring 4032, and the other side of the second spring 4032 is fixedly connected to the inner wall of the fixing frame 1. The second spring 4032 is sleeved on the outside of the limiting column 4031, and the second spring 4032 is used to provide a reset force for the horizontal movement of the rack 403.

[0036] It can be further explained that the rotation of the rotating rod 405 drives the spur gear 404 to rotate clockwise, and the rotation of the spur gear 404 drives the two racks 403 to move away from each other, and the rack 403 moves to the side away from the block 401. The movement of the rack 403 drives the moving box 402 to move, and the second spring 4032 is squeezed by force, and the movement of the moving box 402 drives the block 401 to move, and the block 401 moves and separates from the slot 201.

The outer wall of the side detection plate 2 squeezes one side of the card block 401, and squeezes the card block 401 to move toward the inside of the moving box 402. The first spring 4011 is squeezed by force. When the card slot 201 moves to one side of the card block 401, the first spring 4011 returns to its original state and drives the card block 401 to reset and move. The card block 401 resets and moves and engages with the card slot 201. At this time, the side detection plate 2 is connected and fixed to the fixing frame 1. Similarly, the fixing frame 1 is connected and fixed to the upper detection plate 3.

[0038] Secondly, when disassembling the opposite side detection plate 2 and the fixing frame 1, the user rotates the rotating rod 405 clockwise, and the rotating rod 405 rotates to drive the spur gear 404 to rotate clockwise, and the spur gear 404 rotates to drive the two racks 403 to move away from each other, and the rack 403 moves to the side away from the block 401, and the movement of the rack 403 drives the moving box 402 to move, and the second spring 4032 is squeezed by force, and the movement of the moving box 402 drives the block 401 to move, and the block 401 moves and separates from the slot 201. At this time, the side detection plate 2 is separated from the fixing frame 1, and the user can take down the side detection plate 2 with the other hand, and then release the rotating rod 405, the second spring 4032 returns to its original state and drives the block 401 to reset and move through mechanical transmission, and then the upper detection plate 3 is disassembled in the same way;

[0039] Finally, by setting the clamping block 401 and the clamping slot 201, it is convenient to quickly connect the side detection plate 2 and the fixing frame 1, and the fixing frame 1 and the upper detection plate 3. Compared with the method of fixing with multiple bolts, the connection time of the fixing frame 1 and the side detection plate 2 is reduced. At the same time, when inspecting the inside of the fixing frame 1, the disassembly time of the fixing frame 1 and the side detection plate 2 is reduced, which makes it convenient to inspect or replace the electronic components inside the fixing frame 1, and avoids the connection of bolts, making the disassembly of the entire device more convenient, and avoiding the inconvenience of separation of the fixing frame 1 and the side detection plate 2 due to rust of the bolts.
