[0023] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.
[0024] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.
[0025] like Figure 1 -
[0026] Figure 6 As shown, a non-contact detection device for pantograph-catenary offline status includes a base plate 1, a pantograph assembly 2, and a detection element. The base plate 1 is mounted on the top of the vehicle, the pantograph assembly 2 is mounted on the base plate 1, and the detection element is mounted on the base plate 1 at a position corresponding to the lower part of the pantograph assembly 2. At least one set of detection elements is provided.
[0027] The testing component includes a testing box 3, an optical testing head 4, and a cleaning assembly. The testing box 3 is mounted on the substrate 1. The optical testing head 4 is located inside the testing box 3. The testing end of the optical testing head 4 is located on the upper outer side of the testing box 3. The optical testing head 4 includes, but is not limited to, an infrared testing head and an ultraviolet testing head. The connection and information transmission methods of the optical testing head 4 are all publicly available technologies and will not be described in detail here.
[0028] The cleaning assembly includes a cleaning component, a passive adjusting component for adjusting the cleaning component, and a vibrating component that is driven by the vibration of the train. The vibration and shaking generated during train travel cause the vibrating component to elastically expand and contract, thereby driving the passive adjusting component to adjust the cleaning component, so that the cleaning component cleans the optical inspection head 4.
[0029] The cleaning component includes a cleaning arc plate 5 and an auxiliary adjustment rod 13. The cleaning arc plate 5 is an arc-shaped plate adapted to the optical detection head 4. A flexible silicone arc plate is provided on the inner side of the cleaning arc plate 5. Both ends of the cleaning arc plate 5 are movably installed inside the detection box 3. The cleaning arc plate 5 can be rotated and adjusted inside the detection box 3. The cleaning arc plate 5 cleans the optical detection head 4 by rotating the cleaning arc plate 5. The auxiliary adjustment rod 13 is fixedly installed at the bottom end of the cleaning arc plate 5. By pushing the auxiliary adjustment rod 13, the cleaning arc plate 5 rotates through the movably installed axis position.
[0030] The passive adjustment component includes a movable groove 14 and a movable ball 15. The movable groove 14 is formed on the side wall of the auxiliary adjustment rod 13. The movable groove 14 is a strip-shaped groove with arc-shaped ends and arc-shaped inner sides. The movable ball 15 is spherical. The curvature of the movable ball 15 matches the curvature of the inner side of the movable groove 14. The movable ball 15 can be rotated and adjusted at any angle inside the movable groove 14.
[0031] The vibrating component includes a fixed sleeve 6, a relief component 16, and a telescopic spring 17. One end of the fixed sleeve 6 is fixedly installed on the inner wall of the detection box 3, and the other end of the fixed sleeve 6 corresponds to the cleaning component. Specifically, the other end of the fixed sleeve 6 corresponds to the auxiliary adjustment rod 13 on the cleaning component. The telescopic spring 17 is fixedly installed on the side of the fixed sleeve 6 near the cleaning component. The relief component 16 is fixedly installed on the end of the telescopic spring 17 away from the fixed sleeve 6, and the relief component 16 is connected to the passive adjustment component. Specifically, the relief component 16 is connected to the movable ball 15. More specifically, the relief component 16 consists of a relief rod and a relief plate, wherein the relief rod is fixedly installed on the movable ball 15, and the relief plate is fixedly installed on the end of the relief rod away from the movable ball 15, and the other end of the relief plate is connected to the telescopic spring 17.
[0032] The vibration generated by the train's movement causes the extension spring 17 on the vibrating component to extend and retract due to the vibration. This allows the movable ball 15 to be adjusted within the movable groove 14, which in turn drives the auxiliary adjustment rod 13 to adjust its angle. The auxiliary adjustment rod 13 then rotates the cleaning arc plate 5 around the pivot point where it is movably mounted on the optical inspection head 4, thus completing the cleaning operation on the optical inspection head 4.
[0033] The vibrating component also includes a limiting rod 18 and a limiting disc 19. The limiting rod 18 is located inside the telescopic spring 17. One end of the limiting rod 18 is fixedly installed on the relief member 16, and the other end of the limiting rod 18 slides through the corresponding position wall of the fixed sleeve 6 and extends into the interior of the fixed sleeve 6. The limiting disc 19 is fixedly installed on the end of the limiting rod 18 located inside the fixed sleeve 6, and the outer diameter of the limiting disc 19 is compatible with the inner diameter of the fixed sleeve 6.
[0034] By using the limiting rod 18 and the limiting plate 19 to limit the horizontal direction, it is possible to effectively prevent the vibrating component from shifting under vibration and shaking, thereby avoiding the situation where the cleaning component is not properly adjusted.
[0035] The side wall of the detection box 3 is also equipped with an active adjustment component, which can be actively triggered when needed to drive the cleaning component to perform cleaning operations.
[0036] The active adjustment component includes an adjustment arc groove 7, an adjustment rod 8, a telescopic device 10, and a push plate 11. The adjustment arc groove 7 is an arc-shaped groove and is located on the side wall of the detection box 3. The axis of the adjustment arc groove 7 corresponds to the axis of the cleaning arc plate 5. The adjustment rod 8 is located inside the adjustment arc groove 7. One end of the adjustment rod 8 is installed on the side wall of the auxiliary adjustment rod 13, and the other end of the adjustment rod 8 extends to the outside of the detection box 3. The telescopic device 10 is installed on the side wall of the detection box 3. The push plate 11 is fixedly installed at the output end of the telescopic device 10. The position of the telescopic device 10 corresponds to the position of the adjustment rod 8.
[0037] The telescopic device 10 is activated to drive the push plate 11 to move horizontally. When the push plate 11 extends, it pushes the corresponding adjustment rod 8 to move on the adjustment arc groove 7 to adapt. This causes the cleaning arc plate 5 to rotate on the optical inspection head 4 via the auxiliary adjustment rod 13, thus cleaning the optical inspection head 4. When the push plate 11 retracts, the auxiliary adjustment rod 13 will be reset to its initial position by the elastic force of the telescopic spring 17. This process is repeated to complete the adaptation and cleaning of the optical inspection head 4.
[0038] The active adjustment component also includes a movable cylinder 9. The movable cylinder 9 is movably installed on the end of the adjustment rod 8 away from the auxiliary adjustment rod 13. The movable cylinder 9 can rotate on the adjustment rod 8. The rotatable movable cylinder 9 enables the push plate 11 to effectively reduce the resistance generated by the pushing movement when pushing the adjustment rod 8.
[0039] The active adjustment component also includes a flip block 12 and a return spring 20. The flip block 12 is fixedly installed on the top of the push plate 11. The flip block 12 is an arc-shaped block and is made of elastically deformable material. The arc-shaped flip block 12 allows the push plate 11 to push the adjustment rod 8 to its limit position. The adjustment rod 8 can then squeeze the flip block 12 and pass over it. This allows the push plate 11 to continue moving the adjustment rod 8 when it retracts. When the push plate 11 retracts to its limit position, the adjustment rod 8 can still squeeze and pass over the flip block 12. This process repeats, effectively driving the adjustment rod 8 to perform reciprocating adjustment operations to complete the repeated cleaning of the optical detection head 4.
[0040] The inside of the overturning block 12 is hollow, passing through both ends. The return springs 20 are fixedly installed on the inside of the overturning block 12 at intervals. Through the elastic reset of the return springs 20, the overturning block 12 can be quickly reset after the adjusting rod 8 passes over it, thus ensuring the effective operation.
[0041] Working principle and usage process of this utility model:
[0042] When in use, the vibration and shaking generated by the train movement cause the telescopic spring 17 to elastically adjust, thereby pushing the relief member 16. With the assistance of the movable groove 14 and the movable ball 15, the relief member 16 pushes the auxiliary adjustment rod 13 to make a matching adjustment, which drives the cleaning arc plate 5 to rotate on the optical detection head 4 and completes the cleaning of the optical detection head 4.
[0043] When the cleaning demand is large, the telescopic device 10 is activated, which drives the push plate 11 to move horizontally back and forth. This allows the adjusting rod 8 to be adjusted on the adjusting arc groove 7, which in turn drives the auxiliary adjusting rod 13 to be adjusted, so that the cleaning arc plate 5 can be rotated back and forth on the optical inspection head 4 to complete the repeated cleaning operation of the optical inspection head 4.
[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
