Description

Technical Field

[0001] This utility model relates to the field of charging pile gun wire temperature monitoring, and in particular to a DC charging pile gun wire temperature monitoring device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the application of DC charging piles is becoming increasingly widespread. During the charging process, the current transmission of the DC charging pile cable generates heat. If the temperature is too high, it may cause safety accidents such as fires. Therefore, temperature monitoring of the charging pile cable is crucial. Currently, most DC charging pile cable temperature monitoring devices on the market only have a single temperature monitoring function, and they often use a rigid clamping structure to hold and fix the cable. This structure is prone to squeezing damage to the cable due to excessive clamping force during the clamping process, affecting the cable's service life and safety. Secondly, existing DC charging pile cable temperature monitoring devices have unstable contact between the temperature monitoring probe and the cable during temperature detection, resulting in inaccurate monitoring data. To solve the above problems, we propose a DC charging pile cable temperature monitoring device. Utility Model Content

[0003] The main purpose of this invention is to provide a DC charging pile gun wire temperature monitoring device, which can effectively solve the problems in the background technology.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-5 As shown, a DC charging pile gun wire temperature monitoring device includes a monitoring device base 1 and a charging pile gun wire body 16. A movable plate 2 is slidably connected to the upper end of the monitoring device base 1. A buffer assembly 8 is provided on one side of the movable plate 2. A clamping block 9 is provided on one side of the buffer assembly 8. A fixing block 10 is fixedly connected to one side of the monitoring device base 1. The charging pile gun wire body 16 is located between the clamping block 9 and the fixing block 10. Two temperature monitoring probes 11 are slidably connected to the inner side of the fixing block 10.

[0021] In this embodiment, a connecting post 12 is fixedly connected to one side of the temperature monitoring probe 11. The connecting post 12 is slidably connected to the monitoring device base 1. A circular plate 13 is fixedly connected to one side of the connecting post 12. A tension spring 14 is sleeved on the outside of the connecting post 12. The two ends of the tension spring 14 are fixedly connected to the monitoring device base 1 and the circular plate 13, respectively. A transmission line 15 is fixedly connected to one side of the circular plate 13. The transmission line 15 is electrically connected to the temperature monitoring probe 11.

[0022] Specifically, when the clamping block 9 and the fixing block 10 clamp the charging pile gun body 16, the tension of the tension spring 14 can make the circular plate 13 always push the connecting column 12 to move closer to the charging pile gun body 16, so that the temperature monitoring probe 11 always fits against the surface of the gun body, collects temperature data in real time, and transmits it to the monitoring system via the transmission line 15.

[0023] In this embodiment, the upper end of the monitoring device base 1 is provided with a first mounting groove 6 and a second mounting groove 7. The inner side of the first mounting groove 6 is provided with a lead screw 4 rotatably connected to the monitoring device base 1, and the lead screw 4 is threadedly connected to the lower end of the moving plate 2. The inner side of the second mounting groove 7 is provided with a guide rod 5 fixedly connected to the monitoring device base 1, and the guide rod 5 is slidably connected to the lower end of the moving plate 2. The lead screw 4 and the guide rod 5 are spaced apart. One end of the lead screw 4 is fixedly connected to a handwheel 3, and the handwheel 3 is located on the outer side of the monitoring device base 1.

[0024] Specifically, by turning the handwheel 3, the lead screw 4 is driven to rotate in the first mounting groove 6. Since the lead screw 4 is threadedly engaged with the moving plate 2, and the moving plate 2 is sleeved on the guide rod 5 in the second mounting groove 7, the moving plate 2 can slide smoothly on the monitoring device base 1, thereby flexibly adjusting the distance between the clamping block 9 and the fixed block 10, causing the clamping block 9 to gradually approach and clamp the charging pile gun body 16.

[0025] In this embodiment, the buffer assembly 8 includes a first mounting plate 81, which is fixedly connected to the movable plate 2. A guide telescopic column 82 is fixedly connected to one side of the first mounting plate 81, and a second mounting plate 84 is fixedly connected to the other end of the guide telescopic column 82. The second mounting plate 84 is fixedly connected to the clamping block 9. A plurality of buffer springs 83 are provided on the outer side of the guide telescopic column 82, and the two ends of the buffer springs 83 are fixedly connected to the first mounting plate 81 and the second mounting plate 84 respectively.

[0026] Specifically, when the clamping block 9 contacts the charging pile gun cable body 16, the buffer component 8 plays a key role. It is fixedly connected to the moving plate 2 through the first mounting plate 81, and the second mounting plate 84 and the clamping block 9 are integrated. The guide telescopic column 82 connects the two. When the clamping block 9 continues to apply force to clamp the charging pile gun cable body 16, the buffer spring 83 will be compressed by force, and the buffer force will be generated through elastic deformation to avoid the clamping block 9 causing hard squeezing damage to the cable body.

[0027] In this embodiment, a plurality of second rotating seats 86 are fixedly connected along the edge line on one side of the first mounting plate 81. A damper 87 is rotatably connected to the inner side of the second rotating seat 86. A first rotating seat 85 is rotatably connected to the other end of the damper 87. The first rotating seat 85 is fixedly connected to the second mounting plate 84.

[0028] Specifically, the damping structure formed by the first rotating seat 85, the damper 87, and the second rotating seat 86 can limit the moving speed of the clamping block 9, making the clamping process gentler.

[0029] In this embodiment, a rubber anti-slip pad is provided on the outer side of the clamping block 9.

[0030] Specifically, the rubber anti-slip pad on the outside of the clamping block 9 can prevent the gun body from sliding and avoid damage to it by external forces, thus ensuring the reliability and continuity of temperature monitoring.

[0031] It should be noted that this utility model is a DC charging pile gun cable temperature monitoring device. In use, the charging pile gun cable body 16 is first placed between the clamping block 9 and the fixing block 10. Then, the handwheel 3 is rotated, causing the lead screw 4 to rotate within the first mounting groove 6. Since the lead screw 4 is threadedly engaged with the moving plate 2, and the moving plate 2 is fitted onto the guide rod 5 within the second mounting groove 7, the moving plate 2 can slide smoothly on the monitoring device base 1, thereby flexibly adjusting the distance between the clamping block 9 and the fixing block 10, causing the clamping block 9 to gradually approach the charging pile gun cable body 16. When the clamping block 9 contacts the charging pile gun cable body 16, the buffer assembly 8 plays a crucial role. It is fixedly connected to the moving plate 2 via the first mounting plate 81, and the second mounting plate 84 and the clamping block 9 are integrated. A guide telescopic column 82 connects the two. The clamping block 9 continues to apply force to clamp the charging pile gun cable. When the main body 16 is in place, the buffer spring 83 will be compressed, generating buffer force through elastic deformation to prevent the clamping block 9 from causing hard squeezing damage to the cable. At the same time, the damping structure composed of the first rotating seat 85, the damper 87, and the second rotating seat 86 limits the moving speed of the clamping block 9, making the clamping process gentler. When the clamping block 9 and the fixing block 10 clamp the charging pile gun cable main body 16, the tension of the tension spring 14 can make the circular plate 13 always push the connecting column 12 to move closer to the charging pile gun cable main body 16, so that the temperature monitoring probe 11 always adheres to the surface of the gun cable main body, collects temperature data in real time, and transmits it to the monitoring system via the transmission line 15. The rubber anti-slip pad on the outside of the clamping block 9 can prevent the gun cable main body from sliding and avoid damage to it by external forces, ensuring the reliability and continuity of temperature monitoring, which is quite practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
