Technical Field

[0001] This utility model relates to the field of power supply box technology, and more specifically to an integrated power supply box for partial discharge detection of railway catenary. Background Technology

[0002] An integrated power supply box is a low-voltage power supply device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. It is typically used for the rational distribution of electrical energy, facilitating circuit opening and closing operations, and possessing a high level of safety protection. Integrated power supply boxes are commonly used in the partial discharge detection of railway overhead contact lines.

[0003] Chinese patent CN219016523U discloses an integrated power supply box for charging and discharging prismatic batteries, which is equipped with a heat sink and a cooling fan, resulting in good heat dissipation. The spacing between the positive and negative electrode probes can be adjusted to adapt to different battery models, greatly reducing costs.

[0004] However, when connecting the external connector to the wiring port, the patent lacks a mechanism to protect the external connector and the wire because the installation heights are usually different when installing multiple integrated power supply boxes. This can lead to excessive bending at the connection point between the external connector and the wire, resulting in loosening and poor contact between the external connector and the wiring port. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an integrated power supply box for partial discharge detection of railway catenary, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: it includes a housing and a rear panel, the rear panel being fixedly connected to the rear side of the housing. The housing includes connecting plates, and two connecting plates are provided. The front sides of the two connecting plates are fixedly connected to one side of the rear panel. It also includes a tightening mechanism, a positioning mechanism, and a clamping mechanism. The tightening mechanism is located inside the connecting plate and is rotatably connected to the connecting plate. The positioning mechanism is located at the top of the connecting plate and is slidably connected to the tightening mechanism. The clamping mechanism is located between the two connecting plates and is located directly behind the wiring port on the rear panel. Guide plates for guiding the clamping mechanism are fixedly connected to opposite sides of the two connecting plates.

[0007] Furthermore, the tightening mechanism includes a rotating rod, one end of the connecting plate has a moving groove, the bottom end of the rotating rod is rotatably connected to the bottom end inside the moving groove, and the top end of the rotating rod passes through the top end of the connecting plate. An elastic rope is fixedly connected to the periphery of the rotating rod, one end of the elastic rope is fixedly connected to a support plate, a baffle is fixedly connected to the top end of the rotating rod, and two limiting blocks are fixedly connected to the periphery of the rotating rod. The two limiting blocks are symmetrically arranged. A moving hole is opened on one side of each of the two connecting plates, and a connecting rod is fixedly connected to the opposite side of each of the two support plates. The outer wall of the connecting rod fits into the moving hole.

[0008] Furthermore, the positioning mechanism includes a sliding plate, which is disposed on the top of the tightening mechanism. The bottom end of the sliding plate has a plurality of positioning holes arranged in a circular array.

[0009] Furthermore, the inside of the slide plate is slidably connected to the outer wall of the limiting block and the rotating rod.

[0010] Furthermore, it also includes a positioning rod, the bottom end of which is fixedly connected to the top of the connecting plate, and the outer wall of the positioning rod fits into the inside of the positioning hole.

[0011] Furthermore, the clamping mechanism includes a placement plate and a clamping plate. The placement plate is disposed between two connecting plates. The top of the placement plate has two mounting holes, which are symmetrically arranged. A spring is fixedly connected inside each of the two mounting holes. The bottom of the clamping plate is fixedly connected to one end of each of the two springs. A limiting rod is fixedly connected to the bottom of the clamping plate near the two mounting holes. Several placement slots are respectively opened on one side of the clamping plate and one side of the placement plate. A fixing block is fixedly connected to the inner wall of each of the placement slots. A limiting plate is fixedly connected to the bottom of each of the fixing blocks. Several wiring ports are provided on one side of the rear panel. Several limiting plates correspond one-to-one with several wiring ports on one side of the rear panel. A rubber pad is fixedly connected to the inner wall of the limiting plate.

[0012] Furthermore, one end of the guide plate is configured to lift towards the top of the clamping plate, and one corner of the top of the clamping plate is rounded.

[0013] Furthermore, both ends of the placement plate are fixedly connected to one end of each of the two connecting rods.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model uses a rotating rod to rotate, causing an elastic rope to wrap around the rotating rod. The elastic rope then moves the support plate to one side of the rear panel. At this time, one corner of the clamping plate contacts the guide plate. Due to the guidance of the guide plate, the guide plate pushes the clamping plate towards the top of the placement plate. With the help of the rubber pad, it is convenient to restrict and fix the external wiring. At the same time, it can be adjusted according to the size of the external wiring part to avoid damage caused by excessive bending of the external wiring part. The sliding plate moves the positioning hole to fit on the outside of the positioning rod, thereby limiting the position of the support plate. This makes the connection between the external wiring part and the wiring port tighter and avoids loose connection and poor contact. Attached Figure Description

[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] Appendix 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] See attached document Figures 1-6 The device includes a housing 1 and a rear panel 24. The rear panel 24 is fixedly connected to the rear side of the housing 1. The housing 1 includes a connecting plate 2. There are two connecting plates 2. The front sides of the two connecting plates 2 are fixedly connected to one side of the rear panel 24. The device also includes a tightening mechanism, a positioning mechanism, and a clamping mechanism. The tightening mechanism is located inside the connecting plate 2 and is rotatably connected to the connecting plate 2. The positioning mechanism is located at the top of the connecting plate 2 and is slidably connected to the tightening mechanism. The clamping mechanism is located between the two connecting plates 2 and is located directly behind the wiring port on the rear panel 24. The two connecting plates 2 are fixedly connected to opposite sides with guide plates 23 for guiding the clamping mechanism.

[0026] In this implementation scheme, the enclosure 1 is equipped with a switching power supply, a data control board, and a switch. It is worth noting that the switching power supply, data control board, and switch are all existing technologies and will not be described in detail here. The multiple wiring ports facilitate the integration of the switching power supply, data control board, and switch into the power supply box, enabling multi-functional operation, including the acquisition of ultrasonic data, processing the data, and sending it to the industrial control computer via TCP / IP protocol. It also converts the AC220V voltage inside the vehicle into different voltage levels such as 15V and 24V to power the ultrasonic probe, temperature and humidity sensor, and GPS on the roof of the vehicle, enabling network connection of the multi-channel probe, temperature and humidity sensor, and control board, and connecting them to the industrial control computer.

[0027] By integrating the power supply, data acquisition and control, and routing functions of the device, the goal of optimizing device space and improving system integration is achieved. Before the improvement, the device consisted of three parts, with a height of approximately 4U and a total weight of approximately 16KG. After the improvement, the device space is approximately 1U and the weight is approximately 8KG. At the same time, the installation time after the improvement is reduced by half compared to the previous version.

[0028] The tightening and positioning mechanisms facilitate a tighter connection between the external wiring head and the wiring port, while also driving the clamping mechanism to move. The clamping mechanism, in conjunction with the guide plate 23, provides protective support for the external wiring, preventing damage caused by excessive bending.

[0029] Specifically, the tightening mechanism includes a rotating rod 4, a moving groove 3 at one end of the connecting plate 2, the bottom end of the rotating rod 4 being rotatably connected to the bottom end of the moving groove 3, and the top end of the rotating rod 4 penetrating the top end of the connecting plate 2. An elastic rope 5 is fixedly connected to the periphery of the rotating rod 4, a support plate 6 is fixedly connected to one end of the elastic rope 5, a baffle 7 is fixedly connected to the top end of the rotating rod 4, and two limiting blocks 8 are fixedly connected to the periphery of the rotating rod 4. The two limiting blocks 8 are symmetrically arranged, a moving hole 19 is opened on one side of each of the two connecting plates 2, and a connecting rod 12 is fixedly connected to the opposite side of each of the two support plates 6. The outer wall of the connecting rod 12 fits into the moving hole 19.

[0030] In this embodiment, when the support plate 6 moves into the moving groove 3, it can drive the connecting rod 12 to move into the moving hole 19.

[0031] Specifically, the positioning mechanism includes a slide plate 9, which is located on top of the tightening mechanism. The bottom of the slide plate 9 has several positioning holes 11 arranged in a circular array.

[0032] In this embodiment, after the slide plate 9 rotates, the slide plate 9 can still drive the positioning hole 11 to be fitted onto the positioning rod 10.

[0033] Specifically, the inside of the slide plate 9 is slidably connected to the outer wall of the limiting block 8 and the rotating rod 4.

[0034] In this embodiment, the slide plate 9 can slide up and down on the outer wall of the rotating rod 4.

[0035] Specifically, it also includes a positioning rod 10, the bottom end of which is fixedly connected to the top of the connecting plate 2, and the outer wall of the positioning rod 10 fits into the inside of the positioning hole 11.

[0036] In this embodiment, the positioning hole 11 is fitted onto the outer wall of the positioning rod 10 by the sliding plate 9, thereby restricting and fixing the rotating rod 4.

[0037] Specifically, the clamping mechanism includes a placement plate 13 and a clamping plate 17. The placement plate 13 is located between two connecting plates 2. Two mounting holes 14 are opened at the top of the placement plate 13. The two mounting holes 14 are symmetrically arranged. Springs 15 are fixedly connected inside each of the two mounting holes 14. The bottom end of the clamping plate 17 is fixedly connected to one end of the two springs 15. Limiting rods 16 are fixedly connected to the bottom end of the clamping plate 17 near the two mounting holes 14. Several placement slots 22 are opened on one side of the clamping plate 17 and one side of the placement plate 13. Fixing blocks 18 are fixedly connected to the inner walls of the several placement slots 22. Limiting plates 20 are fixedly connected to the bottom ends of the several fixing blocks 18. Several wiring ports are provided on one side of the rear panel 24. Several limiting plates 20 correspond one-to-one with several wiring ports on one side of the rear panel 24. Rubber pads 21 are fixedly connected to the inner walls of the limiting plates 20.

[0038] In this embodiment, the rubber pad 21 can be used to adjust the size of the multiple external wires according to their different dimensions.

[0039] Specifically, one end of the guide plate 23 is configured to lift towards the top of the clamping plate 17, and one corner of the top of the clamping plate 17 is rounded.

[0040] In this embodiment, when one corner of the clamping plate 17 contacts the guide plate 23, the clamping plate 17 moves downward due to the guidance of the guide plate 23.

[0041] Specifically, the two ends of the placement plate 13 are fixedly connected to one end of each of the two connecting rods 12.

[0042] In this embodiment, when the support plate 6 moves, it facilitates the movement of the placement plate 13 via the connecting rod 12.

[0043] The working principle and usage process of this utility model are as follows: When in use, firstly, pull the clamp 17 upward, so that the clamp 17 drives the spring 15 to stretch and drives the limiting rod 16 to move upward, thereby increasing the gap between the clamp 17 and the placement plate 13, making it easier for the staff to pass the head end of the external wiring part through the gap between the clamp 17 and the placement plate 13 and connect it to the wiring port on the side of the rear panel 24.

[0044] Next, loosen the clamp 17 so that the clamp 17 returns to its original position under the left and right sides of the spring 15. This causes the clamp 17 to push the rubber pad 21 at the bottom of the limiting plate 20 to press against the periphery of the external wiring. This can be adjusted according to the different sizes of multiple external wirings, thereby confining the external wiring inside the placement groove 22 and preventing excessive bending of the external wiring part from causing damage.

[0045] Next, pull the slide plate 9 upwards. The slide plate 9 slides on the outer wall of the limiting block 8 and the rotating rod 4. At this time, the positioning rod 10 separates from the positioning hole 11. Rotate the rotating rod 4 so that the elastic rope 5 is wrapped around the rotating rod 4. The elastic rope 5 drives the support plate 6 to move to the side of the rear panel 24. The support plate 6 drives the connecting rod 12 to move into the moving hole 19. At this time, one corner of the clamping plate 17 contacts the guide plate 23. Due to the guidance of the guide plate 23, the guide plate 23 drives the clamping plate 17 to press against the top of the placement plate 13. The limiting plate 20 restricts and fixes the external wiring through the rubber pad 21. Release the slide plate 9 so that the slide plate 9 slides downwards. At the same time, the slide plate 9 drives the positioning hole 11 to be sleeved on the outside of the positioning rod 10, thereby limiting the position of the support plate 6. This makes the connection between the external wiring part and the wiring port tighter and avoids loose connection and poor contact.

[0046] 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.
