Description

Technical Field

[0001] This utility model belongs to the field of grounding device technology, and particularly relates to a fast grounding device, electromechanical equipment, and high-speed train. Background Technology

[0002] The primary function of a grounding device is to safely conduct excess charge from circuits or electrical equipment to the earth, thereby preventing safety issues caused by charge accumulation. Taking high-voltage cable testing of high-speed trains as an example, the test voltage is high. If the cable is not properly grounded, charge accumulation may occur, affecting the accuracy of test data and even endangering the safety of test personnel. Furthermore, the grounding location needs to change frequently during the experiment. Current grounding devices mainly use grounding stakes, bolted grounding wires, and heavy-duty grounding clamps, which are inconvenient to use, and extremely cumbersome to install and dismantle, significantly impacting the test progress. Therefore, providing a device that is portable, easy and quick to install and dismantle, and provides excellent grounding performance is a pressing technical problem that needs to be solved in this field. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, the present invention provides a fast grounding device, comprising: a magnet assembly, a connecting assembly, and a grounding assembly; the magnet assembly is disposed on the side of the connecting assembly;

[0004] The connecting component has a through hole in the center;

[0005] The grounding component passes through the first hole of the connecting component, with the first end grounded and the second end connected to the device to be grounded.

[0006] Furthermore, the connecting component also includes a second hole disposed on the side and corresponding to the magnet component;

[0007] The magnet assembly is detachably mounted inside the second hole.

[0008] Furthermore, the second hole and the magnet assembly are divided into several groups, with several in each group, and are symmetrically distributed in pairs along the outer side of the first hole.

[0009] Furthermore, both the second hole and the end face of the magnet assembly are crescent-shaped;

[0010] The magnet assembly has a limit plate at its top.

[0011] The maximum width of the limiting plate is greater than the diameter of the second hole.

[0012] Furthermore, the magnet assembly includes: a magnet, a protective shell, and a flexible layer disposed around the protective shell;

[0013] The protective shell is made by injection molding to cover the magnet.

[0014] Furthermore, a cylindrical mounting tube is provided at one end of the first hole on the connecting component; the mounting tube is made of plastic deformation material and is connected to the grounding component through plastic deformation.

[0015] Furthermore, the grounding assembly includes: a grounding wire and a winding plate disposed inside the first hole; a portion of the grounding wire is wound on the winding plate.

[0027] This utility model provides a fast grounding device, reference Figure 1 and 2 It includes: magnet assembly 1, connection assembly 2 and grounding assembly;

[0028] Magnet assembly 1 is disposed on the side of the connecting assembly;

[0029] Connecting component 2 has a through hole 21 in the center;

[0030] The grounding component passes through the first hole 21 of the connecting component, with the first end grounded and the second end connected to the device to be grounded.

[0031] This embodiment provides a rapid grounding device. In use, a magnetically attractable object, such as a metal object, is located near the grounding point. The magnet assembly is brought close to the selected grounding point, and the magnet assembly, located on the side of the connecting component, will automatically adhere to that location without the need for bolts or clamps, enabling rapid installation of the grounding device. The grounding component, passing through the first hole on the connecting component, connects its second end to the device to be grounded, completing the rapid grounding of the device. Because a magnetic fixing method replaces traditional bolt or clamp fixing methods, the installation and disassembly of the grounding device are much faster. The magnetic attraction provides a larger contact area, resulting in more uniform contact points compared to traditional clamps, avoiding wear and damage to the magnetically attracted object, greatly reducing mechanical wear, and improving service life. Preferably, the grounding component uses a highly conductive and wear-resistant conductor, such as copper wire, to ensure unobstructed grounding circuitry. The specific conductor length and cross-sectional area can be calculated and selected by those skilled in the art based on the voltage and current to meet grounding requirements. In summary, this utility model provides a rapid grounding device that is portable, easy and quick to install and disassemble, and provides excellent grounding performance.

[0032] Preferred, Reference Figure 1 and Figure 2 The connecting component 2 also includes a second hole 22 disposed on the side and corresponding to the magnet component 1;

[0033] The magnet assembly 1 is detachably installed in the second hole 22.

[0034] In this embodiment, the connecting assembly has a second hole on its side for accommodating the magnet assembly, allowing for its removal and installation. This enables quick replacement of the magnet assembly should it fail or be damaged. The magnetic force of the magnet assembly can also be adjusted by changing the depth of insertion into the second hole, improving the adjustability of the device. More importantly, when magnetic fixation is not required, the magnet assembly can be directly removed, and the device can be fixed to a fixed point using fixing pins, screws, or by directly snapping it in through the second hole, further expanding the device's applicability.

[0035] More preferably, the second hole and the magnet assembly are divided into several groups, with several units in each group, and symmetrically distributed in pairs along the outer side of the first hole. Because the magnet assemblies are symmetrically distributed in pairs, the adsorption force is evenly distributed across multiple points, preventing displacement or loosening due to uneven force, and improving long-term stability. Furthermore, through the multiple magnet assembly mounting holes, operators can freely adjust the position and number of magnet assemblies to accommodate magnetically adsorbed objects of different shapes and sizes, making the arrangement of the quick grounding device more flexible. For example, see reference. Figure 1 and Figure 2The number of the second hole 22 and the magnet assembly 1 is 4, divided into two groups of two, which are symmetrically distributed on the outside of the first hole 21.

[0036] Preferred, Reference Figure 1 and Figure 2 and Figure 3 Both the second hole 22 and the end face of the magnet assembly 1 are crescent-shaped;

[0037] Magnet assembly 1, with a limiting plate 3 at its top;

[0038] The maximum width of the limiting plate 3 is greater than the diameter of the second hole 22.

[0039] In this embodiment, since both the second hole and the end face of the magnet assembly are crescent-shaped, the magnet assembly can be better embedded in the hole, improving the contact area and installation stability. Compared with traditional round or square holes, it provides better force distribution, preventing the magnet assembly from loosening or falling off due to vibration or impact. A limiting plate is provided at the top of the magnet assembly. The maximum width of the limiting plate is greater than the diameter of the second hole, ensuring that the magnet will not fall out directly after installation, but will be firmly fixed in the hole, preventing the magnet assembly from shifting or accidentally falling off within the hole.

[0040] Preferably, the magnet assembly includes: a magnet, a protective shell, and a flexible layer disposed around the protective shell;

[0041] The protective shell is made by injection molding to cover the magnet.

[0042] In this embodiment, the magnet located in the inner layer provides strong magnetic attraction, ensuring that the device can firmly adhere to the magnetically adsorbed object. The protective shell is injection molded to cover the magnet, effectively preventing damage to the magnet during long-term use due to impact, wear, or environmental factors (such as moisture or corrosion). The flexible layer surrounding the protective shell provides additional cushioning, preventing damage to the metal surface during magnet adsorption or disassembly, while also improving the device's shock resistance. Furthermore, the flexible layer allows the magnet assembly to better adapt to the shape of the second hole, ensuring a tight fit and preventing loosening due to vibration or external forces.

[0043] Preferred, Reference Figure 1 A cylindrical mounting tube 4 is provided at one end of the first hole 21 on the connecting component 2; the mounting tube 4 is made of plastic deformation material and is connected to the grounding component by plastic deformation.

[0044] In this embodiment, a mounting tube is provided at one end of the first hole of the connecting component. The mounting tube's snap-fit ​​design ensures the grounding component is not easily detached, improving grounding stability. More preferably, the diameter of the mounting tube is the same as the diameter of the first hole, allowing for better installation of the mounting tube with the connecting component. For example, the mounting tube is made of galvanized copper or other materials with plastic deformation properties.

[0045] Preferably, the grounding assembly includes: a grounding wire and a winding plate disposed inside the first hole; a portion of the grounding wire is wound on the winding plate.

[0046] In this embodiment, the operator can easily adjust the length of the grounding wire by simply rotating or pulling the winding plate to unfold or retract the wire. This avoids tangling and messiness of the grounding wire, as well as preventing the wire from becoming scattered or accidentally pulled, thus reducing the probability of electrical safety accidents. More preferably, the winding plate is disc-shaped or ring-shaped to make full use of space and improve storage efficiency.

[0047] The grounding assembly also includes a current detector and an alarm connected in parallel with the grounding conductor.

[0048] In this embodiment, the current detector and the alarm are connected in parallel with the grounding conductor, allowing for real-time monitoring of current changes as the grounding conductor transmits current. If the grounding current overloads or exceeds a preset safety range, the current detector will immediately detect the abnormal current, and the alarm will sound an alarm. This parallel connection allows the current detector and the alarm to operate independently without interfering with normal grounding current flow, while also ensuring timely alarm activation in case of current anomalies, thus improving device safety. More preferably, the alarm includes an alarm light and / or a buzzer; through a combination of sound and light, it alerts operators to potential faults such as excessive current or poor grounding, making the grounding device even safer.

[0049] An electromechanical device comprising any one of the above-mentioned fast grounding devices.

[0050] In this embodiment, an electromechanical device is provided, which, by being equipped with any of the above-mentioned fast grounding devices, can effectively achieve stable transmission of grounding current, while ensuring electrical safety and ease of operation during the device's operation.

[0051] A type of high-speed train includes any of the above-mentioned fast grounding devices.

[0052] In this embodiment, a high-speed train is provided that, by equipping any of the aforementioned rapid grounding devices, the high-voltage cable system of the high-speed train is quickly grounded using magnetic adsorption. This device eliminates the need for complex bolt connections, greatly simplifying the grounding operation and ensuring the stability and safety of the grounding current. More preferably, the rapid grounding device is used in high-voltage cable testing of high-speed trains. Because this rapid grounding device can be installed on the rails, it adapts to the frequent disassembly and installation of grounding devices during testing, greatly improving testing efficiency and safety.

[0053] The aforementioned electromechanical equipment and EMU trains are created based on the aforementioned fast grounding device, and the combination of their technical effects and features will not be elaborated further here. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
