Description

Technical Field

[0001] This utility model relates to the field of electrical fire prevention technology, specifically to an electrical fire detection and monitoring device for charging piles and charging stations. Background Technology

[0002] Defects such as air bubbles, gaps, impurities, and spikes inside the insulation of high-voltage electrical equipment can cause uneven electric field distribution within the switchgear insulation under the influence of a strong electric field. The electric field strength increases at the defective locations, making them prone to partial discharges that do not penetrate the entire insulation. Monitoring and detecting partial discharges in electrical equipment is an important means of assessing the insulation condition of the equipment, as well as an effective measure to detect latent faults, ultimately achieving fault early warning and preventing faults from occurring.

[0003] Testing charging piles or charging stations typically utilizes ultra-high frequency sensors, ground wave sensors, and ultrasonic sensors to monitor partial discharge signals during the operation of electrical equipment. This allows for the determination of potential insulation defects within high-voltage electrical equipment and provides early warnings. Currently, existing monitoring devices usually employ partial discharge monitoring smart terminals to test charging piles or charging stations. These smart terminals are typically magnetic and need to be attached to the casing of the charging pile or charging station to test the cables. However, some charging piles or charging stations are not made of magnetic metals such as iron, nickel, or cobalt, making it impossible for the partial discharge monitoring smart terminals to attach to the casing. This increases the difficulty of testing for personnel and reduces the efficiency of the testing device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electrical fire detection and monitoring device for charging piles and charging stations. It solves the problem that the shells of some existing charging piles or charging stations are not made of magnetic metals such as iron, nickel, and cobalt, which makes it impossible for the partial discharge monitoring smart terminal to be attached to the shell of the charging pile or charging station, increasing the difficulty of detection for staff and thus reducing the detection efficiency of the detection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical fire detection and monitoring device for charging piles and charging stations, comprising a mounting base and a partial discharge monitoring intelligent terminal body. A pair of support plates are mounted on the mounting base. A first support block is movably disposed on the support plates. A cavity is provided within the first support block. A second support block is movably disposed within the cavity. A second sliding groove is provided within the cavity. A second slider is fixedly mounted on the second support block. The second support block is slidably mounted within the second sliding groove via the second slider. A pair of limiting grooves are provided within the first support block. A pair of second support columns are movably disposed within the first support block. One end of each second support column is provided with a limiting block, which is movably disposed within the limiting groove. The other end of each second support column is connected to the second support block. A pressure block is mounted on the second support block. An mounting block is provided on the first support block. A groove is provided on the mounting block. The pressure block is movably disposed within the groove. The partial discharge monitoring intelligent terminal body is movably disposed within the mounting block. A rubber plate is fixedly mounted on the pressure block. The rubber plate is movably disposed on the partial discharge monitoring intelligent terminal body.

[0006] Preferably, the first support block is provided with a pair of first sliders, the support plate is provided with a first groove, the first support block is slidably installed in the first groove by the first sliders, the support plate is provided with a plurality of second pin holes, the first slider is provided with a first pin hole, and the first pin hole and the second pin hole are matched.

[0007] Preferably, a first support column is rotatably disposed inside the first support block, a handle is provided on one end of the first support column, and a lead screw is provided on the other end of the first support column, the lead screw being screwed into the second slider.

[0008] Preferably, a baffle is movably mounted on the support plate.

[0009] Preferably, the mounting base is provided with two pairs of bolt holes.

[0010] Beneficial effects

[0011] This utility model provides an electrical fire detection and monitoring device for charging piles and charging stations, which has the following features:

[0012] Beneficial effects:

[0013] This design drives the handle to rotate, which in turn rotates the first support column, controls the lead screw to rotate, moves the second slider, moves the second support block, and controls the pressure block to move. This causes the rubber plate to press against the partial discharge monitoring smart terminal body, ensuring that the detection end of the partial discharge monitoring smart terminal body is tightly attached to the charging pile and its shell. This avoids the situation where the partial discharge monitoring smart terminal cannot be attached to the charging pile or charging station shell because the shell is not made of magnetic metals such as iron, nickel, or cobalt. This reduces the detection difficulty for staff and improves the detection efficiency of the detection device.

[0014] The limiting block in this design is movably set in the limiting groove. By controlling the movement distance of the second support column, the movement distance of the second support block can be controlled, which in turn controls the movement distance of the pressure block. This can prevent the pressure block from moving and squeezing the partial discharge monitoring smart terminal body, thus avoiding damage to the partial discharge monitoring smart terminal body and increasing its service life.

[0015] The second support block of this design is slidably installed in the second groove via the second slider, which can play a guiding role and control the movement direction of the second slider, thereby controlling the movement direction of the second support block. This avoids the situation where the pressure block cannot enter the groove due to the offset of the second support block during movement, thus improving the installation efficiency of the detection device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: an electrical fire detection and monitoring device for charging piles and charging stations, including a mounting base 1 and a partial discharge monitoring intelligent terminal body 7. A pair of support plates 2 are mounted on the mounting base 1. A first support block 6 is movably disposed on the support plate 2. A cavity 11 is provided inside the first support block 6. A second support block 12 is movably disposed inside the cavity 11. A second sliding groove 19 is provided inside the cavity 11. A second slider 18 is fixedly mounted on the second support block 12. The second support block 12 is slidably mounted in the second sliding groove 19 via the second slider 18. A pair of limiting grooves 23 are provided inside the first support block 6. The device is equipped with a pair of second support columns 13. One end of each second support column 13 is provided with a limiting block 22, which is movably disposed within the limiting groove 23. The other end of the second support column 13 is connected to the second support block 12. A pressure block 14 is installed on the second support block 12. An installation block 17 is provided on the first support block 6. A groove 16 is provided on the installation block 17, and the pressure block 14 is movably disposed within the groove 16. The partial discharge monitoring intelligent terminal body 7 is movably disposed within the installation block 17. A rubber plate 15 is fixedly installed on the pressure block 14, and the rubber plate 15 is movably disposed on the partial discharge monitoring intelligent terminal body 7.

[0022] The partial discharge monitoring intelligent terminal body 7 is an intelligent terminal manufactured by Shanxi Changyu Electric Power Automation Co., Ltd., and its model is: CY-PD300;

[0023] The mounting block 17 is provided with a mounting slot, and the partial discharge monitoring intelligent terminal body 7 is installed in the mounting slot of the mounting block 17.

[0024] The rubber sheet 15 can prevent the pressure block 14 from directly contacting the partial discharge monitoring smart terminal body 7, thus avoiding damage to the partial discharge monitoring smart terminal body 7.

[0025] The limiting block 22 is movably set in the limiting groove 23. By controlling the moving distance of the second support column 13, the moving distance of the second support block 12 can be controlled, and thus the moving distance of the pressure block 14 can be controlled. This can prevent the pressure block 14 from moving and squeezing the partial discharge monitoring smart terminal body 7, which would cause damage to the partial discharge monitoring smart terminal body 7, thereby increasing the service life of the partial discharge monitoring smart terminal body 7.

[0026] The second support block 12 is slidably installed in the second slide groove 19 via the second slider 18. It can play a guiding role, control the movement direction of the second slider 18, and thus control the movement direction of the second support block 12. This avoids the situation where the pressure block 14 cannot enter the groove 16 due to the deviation of the second support block 12 during movement, thereby improving the installation efficiency of the detection device.

[0027] In this embodiment, the first support block 6 is provided with a pair of first sliders 8, the support plate 2 is provided with a first groove 9, the first support block 6 is slidably installed in the first groove 9 through the first sliders 8, the support plate 2 is provided with a plurality of second pin holes 4, the first sliders 8 are provided with first pin holes 3, and the first pin holes 3 and the second pin holes 4 are matched.

[0028] The first support block 6 is slidably installed in the first slide groove 9 via the first slider 8. The movement of the first support block 6 can be controlled, and the height of the first support block 6 can be adjusted, thereby adjusting the position of the partial discharge monitoring smart terminal body 7, so that the detection end of the partial discharge monitoring smart terminal body 7 moves to the detection position.

[0029] The first pin hole 3 and the second pin hole 4 are fixed by locating pins.

[0030] In this embodiment, a first support column 21 is rotatably disposed inside the first support block 6. A handle is provided on one end of the first support column 21, and a lead screw 20 is provided on the other end of the first support column 21. The lead screw 20 is screwed into the second slider 18.

[0031] The drive handle rotates, causing the first support column 21 to rotate, the control screw 20 to rotate, causing the second slider 18 to move, which in turn causes the second support block 12 to move, and the control block 14 to move. This causes the rubber plate 15 to press against the partial discharge monitoring smart terminal body 7, ensuring that the detection end of the partial discharge monitoring smart terminal body 7 is tightly attached to the charging pile and its housing. This avoids the situation where the partial discharge monitoring smart terminal cannot be attached to the housing of some charging piles or charging stations because the housing is not made of magnetic metals such as iron, nickel, or cobalt. This reduces the difficulty of detection for staff and improves the detection efficiency of the detection device.

[0032] In this embodiment, a baffle 5 is movably mounted on the support plate 2;

[0033] The baffle 5 is a detachable baffle that serves as a limit and prevents the first slider 8 from disengaging from the first slide groove 9 when the first support block 6 moves.

[0034] In this embodiment, the mounting base 1 is further provided with two pairs of bolt holes 10;

[0035] Bolt hole 10 allows staff to easily fix the detection device near the charging pile and charging station using expansion bolts.

[0036] Example: During installation, the operator uses expansion bolts to fix the mounting base 1 near the charging pile or charging station through the bolt holes 10. The operator then rotates the handle, causing the first support column 21 to rotate, and controls the lead screw 20 to rotate, moving the second slider 18 and the second support block 12. This moves the pressure block 14 into the cavity 11. The mounting block 17 has a mounting groove. The partial discharge monitoring intelligent terminal body 7 is installed in the mounting groove of the mounting block 17, with the detection end of the partial discharge monitoring intelligent terminal body 7 facing the area to be detected in the charging pile or charging station. The baffle 5 is removed, and the first support block 6 is slidably installed via the first slider 8. Within the first slide groove 9, the first support block 6 can be moved and its height adjusted, thereby adjusting the position of the partial discharge monitoring intelligent terminal body 7, so that the detection end of the partial discharge monitoring intelligent terminal body 7 moves to the detection position. Using a positioning pin inserted between the first pin hole 3 and the second pin hole 4, the first slider 8 can be fixed at the detection position, and the first support block 6 can be fixed at its current position. Bolts are used to fix the baffle 5 to the support plate 2. Driving the handle to rotate causes the first support column 21 to rotate, controlling the screw 20 to rotate, causing the second slider 18 to move, which in turn moves the second support block 12, controlling the pressure block 1. 4. The movement causes the rubber plate 15 to press against the partial discharge monitoring smart terminal body 7, ensuring that the detection end of the partial discharge monitoring smart terminal body 7 is tightly attached to the charging pile and its housing. This avoids situations where the partial discharge monitoring smart terminal cannot adhere to the housing of some charging piles or charging stations because the housing is not made of magnetic metals such as iron, nickel, or cobalt. This reduces the difficulty of detection for staff and improves the detection efficiency of the detection device. The second support block 12 is slidably installed in the second slide groove 19 via the second slider 18, which can serve as a guide and control the movement of the second slider 18. The direction of movement of the second support block 12 is controlled, thereby preventing the pressure block 14 from failing to enter the groove 16 due to deviation of the second support block 12 during movement. This improves the installation efficiency of the detection device. The limiting block 22 is movably set in the limiting groove 23. By controlling the movement distance of the second support column 13, the movement distance of the second support block 12 can be controlled, thereby controlling the movement distance of the pressure block 14. This prevents the pressure block 14 from squeezing the partial discharge monitoring smart terminal body 7 and causing damage to the partial discharge monitoring smart terminal body 7, thereby increasing the service life of the partial discharge monitoring smart terminal body 7.
