Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic shielding technology, and more specifically, it relates to a shielding structure for LED work lights in underground equipment that resists electromagnetic interference. Background Technology

[0002] In underground locations such as underground substations and underground parking garages, in order to ensure the stable and reliable operation of underground equipment LED work lights and avoid the influence of electromagnetic interference, it is necessary to use an electromagnetic interference-resistant shielding structure for underground equipment LED work lights. This shields the LED work lights from electromagnetic interference, allowing them to emit light normally in environments with strong electromagnetic interference, and providing good visual conditions for underground workers.

[0003] However, traditional LED work light shielding structures lack ventilation and heat dissipation, causing heat to accumulate in the limited space during prolonged operation in harsh underground environments. The poor ventilation of traditional structures, coupled with sustained high temperatures, easily leads to unstable light brightness. Furthermore, traditional structures lack the ability to quickly lay out wiring. During installation, the layout and organization of wiring is time-consuming and labor-intensive, and problems such as wire crossings and compression can easily cause short circuits and other malfunctions, affecting the normal operation of underground facilities and personnel safety. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an electromagnetic interference-resistant shielding structure for LED work lights in underground equipment, thereby solving the technical problem that existing shielding structures for LED work lights in underground equipment lack ventilation, heat dissipation, and rapid wiring arrangements.

[0005] The purpose and effectiveness of the electromagnetic interference-resistant LED work light shielding structure for underground equipment of this utility model are achieved by the following specific technical means:

[0006] An electromagnetic interference resistant shielding structure for underground equipment LED work lights includes a mounting plate. The bottom of the mounting plate has multiple sets of wire grooves for quick circuit arrangement and improved circuit layout. The bottom of the mounting plate also has multiple sets of first connecting plates, each with a shielding component. The shielding component has a first mounting slot, within which an LED light is positioned and connected to the mounting plate. Below the LED light is a ring-shaped mounting bracket, the top of which is connected to the shielding component. The bottom of the ring-shaped mounting bracket has a light-transmitting element for electromagnetic shielding.

[0007] According to a preferred embodiment, the wire groove includes a groove body and a wire cylinder. Four sets of mounting brackets are symmetrically installed on both sides of the groove body. The groove body is mounted on the bottom of the mounting plate through the mounting brackets. Four sets of mounting components are symmetrically installed on the groove body. The wire cylinder is mounted in the groove body through the mounting components.

[0008] According to a preferred embodiment, a first ventilation channel is formed between the trough and the mounting plate, and ventilation slots are provided on both the trough and the wire cylinder.

[0009] According to a preferred embodiment, the mounting component includes a sliding frame and a sliding block. The sliding frame is connected to the groove and forms a sliding groove with the groove. The sliding block is slidably connected to the sliding groove. Two sets of springs are installed between the sliding block and the sliding frame. The sliding block is conical.

[0010] According to a preferred embodiment, the shielding assembly includes six sets of second connecting plates and four sets of shielding waveguides, with three sets of second ventilation channels formed between the four sets of shielding waveguides, and the six sets of second connecting plates are symmetrically installed in pairs between the three sets of second ventilation channels.

[0011] According to a preferred embodiment, the light-transmitting component includes a high-transmittance electromagnetic shielding film and an annular support frame. Both the annular support frame and the annular mounting frame are provided with a second mounting groove, and a magnetic pad for auxiliary installation is installed on the second mounting groove. The high-transmittance electromagnetic shielding film is installed between the annular support frame and the annular mounting frame.

[0012] According to a preferred embodiment, a temperature sensor is mounted on the top of the LED light; a third ventilation channel is formed between the mounting plate and the shielding assembly.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, through the setting of wire grooves and ventilation grooves, enables the device to quickly arrange circuits and improve circuit layout, while having good heat dissipation performance, thus improving the practicality and stability of the device. The device can install the groove on the bottom of the mounting plate through the mounting brackets symmetrically installed on both sides of the groove. The wire tube is installed through the mounting components to achieve fast and orderly wiring. This allows the device to complete wiring installation and organization even in limited underground spaces. Furthermore, the first ventilation channel formed between the groove and the mounting plate, as well as the ventilation grooves opened on the groove and the wire tube, can enhance air circulation and remove the heat generated by the LED work lights, thus improving the device's heat dissipation capabilities.

[0015] 2. When using this device, the reasonable layout of six sets of second connecting plates and four sets of shielding waveguides in the shielding assembly forms three sets of second ventilation channels, which enhances the ventilation and heat dissipation effect, allowing the internal heat of the device to dissipate quickly and improving the device's heat dissipation capacity in the complex underground environment. Then, through the cooperation of the high-transmittance electromagnetic shielding film in the light-transmitting component and the ring support frame, as well as the magnetic pad assisted installation, the device can shield electromagnetic interference while ensuring sufficient light transmittance, ensuring that the LED lights can pass through normally.

Detailed Implementation

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 2 As shown, this utility model provides a shielding structure for LED work lights in underground equipment that resists electromagnetic interference.

[0025] First, the structure includes a mounting plate 11; the mounting plate 11 provides basic support for the entire shielding structure; this allows the device to be installed in the required location for underground equipment, improving the stability of the device installation.

[0026] The bottom of the mounting plate 11 is equipped with multiple sets of wire slots for quickly arranging circuits and improving circuit layout; the device can arrange circuits through the wire slots; in this way, the device can quickly organize the circuits in complex underground environments, improve the convenience of circuit layout, and enhance the device's ability in circuit layout.

[0027] The wire trough consists of a trough body 12 and a wire tube 13. By setting up the trough body 12 and the wire tube 13, different wires can be classified and arranged to avoid wire chaos and improve the regularity of the circuit of the device.

[0028] Four sets of mounting brackets 14 are symmetrically installed on both sides of the tank 12. The tank 12 is installed on the bottom of the mounting plate 11 through the mounting brackets 14. This installation method ensures the connection between the tank 12 and the mounting plate 11, so that the device can still maintain the stability of the tank 12 in the environment of possible underground vibration, improve the reliability of the device structure, and enhance the installation capability.

[0029] Four sets of mounting components are symmetrically installed on the tank 12. The wire tube 13 is installed in the tank 12 through the mounting components. The mounting components include a sliding frame 15 and a sliding block 16. The sliding frame 15 is connected to the tank 12 and forms a sliding groove with the tank 12. The sliding block 16 is slidably connected to the sliding groove. Two sets of springs 17 are installed between the sliding block 16 and the sliding frame 15. The sliding block 16 is conical. This mounting component setting facilitates the installation and disassembly of the wire tube 13. When the device needs to be repaired or the wire tube 13 needs to be replaced, the operation is simpler and the maintenance convenience of the device is improved.

[0030] A first ventilation channel is formed between the trough 12 and the mounting plate 11. Ventilation slots are provided on both the trough 12 and the wire cylinder 13. The device can promote air circulation through these ventilation channels and slots, remove the heat generated by the LED work lights, improve heat dissipation efficiency, and enhance the device's heat dissipation capabilities. The first ventilation channel and slots also allow for better arrangement of cable ties, improving the speed and convenience of wire arrangement.

[0031] Multiple sets of first connecting plates 18 are also installed at the bottom of the mounting plate 11, and shielding components are installed at the bottom of the multiple sets of first connecting plates 18. Through the setting of the first connecting plates 18, a reliable connection between the mounting plate 11 and the shielding components is realized, so that the device can install the shielding components in a designated position.

[0032] The shielding assembly includes six sets of second connecting plates 19 and four sets of shielding waveguides 21; three sets of second ventilation channels are formed between the four sets of shielding waveguides 21, and the six sets of second connecting plates 19 are symmetrically installed in pairs between the three sets of second ventilation channels; through this shielding assembly structure, the electromagnetic shielding effect and ventilation and heat dissipation capacity are enhanced; the device can not only shield electromagnetic interference, but also further improve heat dissipation efficiency, thereby improving the overall performance in terms of anti-electromagnetic interference and heat dissipation, and enhancing the device's ability to cope with complex underground electromagnetic and thermal environments.

[0033] The shielding assembly has a first mounting slot, in which an LED light 22 is installed, and its top is connected to the mounting plate 11. The first mounting slot is provided to position the LED light 22, thereby improving the installation accuracy of the device.

[0034] A temperature sensor 23 is installed on the top of the LED light 22. Through the temperature sensor 23, the device can monitor the temperature of the LED light 22, detect abnormal temperature conditions in a timely manner, improve the temperature monitoring capability, and enhance the ability to ensure the stable operation of the LED light 22.

[0035] Below the LED light 22, there is a ring-shaped mounting bracket 24. The top of the ring-shaped mounting bracket 24 is connected to the shielding component, and the bottom of the bracket is equipped with a light-transmitting component for shielding electromagnetic fields. The ring-shaped mounting bracket 24 provides support for the light-transmitting component, enabling the device to install the light-transmitting component and improving the structural integrity of the device.

[0036] The light-transmitting component includes a high-transmittance electromagnetic shielding film 25 and an annular support frame 26. Both the annular support frame 26 and the annular mounting frame 24 have second mounting slots, and magnetic pads 27 for auxiliary installation are installed in these slots. The high-transmittance electromagnetic shielding film 25 is installed between the annular support frame 26 and the annular mounting frame 24. The installation of the high-transmittance electromagnetic shielding film 25 is aided by the magnetic pads 27, simplifying the installation process and enabling the device to more easily assemble the light-transmitting component, thus improving installation convenience and enhancing the device's capabilities in light-transmitting component installation.

[0037] The combination of the high-transmittance electromagnetic shielding film 25 and the annular support frame 26 ensures good light transmission while shielding electromagnetic interference, thus improving the device's performance in both electromagnetic shielding and light transmission, and meeting the dual requirements of underground LED work light illumination and electromagnetic interference resistance.

[0038] In addition, a third ventilation channel is formed between the mounting plate 11 and the shielding assembly, which further enhances the ventilation and heat dissipation effect of the device; this enables the device to maintain good heat dissipation even in an underground enclosed environment, thus improving the overall heat dissipation performance of the device.

[0039] The specific usage and function of this embodiment are as follows:

[0040] First, the tank 12 is fixed to the bottom of the mounting plate 11 with bolts through four sets of mounting brackets 14 symmetrically installed on both sides. This installation method ensures the connection between the tank 12 and the mounting plate 11, so that the tank 12 can reliably bear the subsequent wiring, while providing structural stability for the device in the harsh environment such as vibration that it may face underground, thus improving the reliability of the device structure.

[0041] After the tank 12 is successfully installed onto the mounting plate 11, the mounting plate 11 with the tank 12 is installed at the designated location of the underground equipment. The mounting plate 11 provides basic support for the entire shielding structure, enabling it to be placed where the underground equipment needs to be, thereby improving the stability of the device installation and ensuring that the entire device can operate stably in the underground environment.

[0042] After the device is installed in place, the wiring is laid out. Utilizing the structural feature of the wire groove, which consists of a groove body 12 and a wire cylinder 13, different types of wires are classified and placed in the wire cylinder 13. Then, the wire cylinder 13 is fixed in the groove body 12 by four sets of mounting components symmetrically installed on the groove body 12. Among the mounting components, the sliding frame 15 and the groove body 12 form a sliding groove, and the sliding block 16 slides in the sliding groove. Two sets of springs 17 are installed between the sliding block 16 and the sliding frame 15. The sliding block 16 is conical, which facilitates the installation of the wire cylinder 13. At the same time, through this arrangement, different wires are arranged in an orderly manner, avoiding wire chaos and improving the regularity of the device's circuit. This allows the device to quickly organize the wiring in complex underground environments, improving the convenience of wiring layout and enhancing the device's capabilities in circuit layout.

[0043] Temperature sensor 23 is installed on top of LED lamp 22, then the wiring is connected to LED lamp 22, and LED lamp 22 is connected to mounting plate 11 with bolts. The first mounting slot positions LED lamp 22, improving the installation accuracy of the device and ensuring that LED lamp 22 can be installed and work normally. Temperature sensor 23 installed on top of LED lamp 22 monitors the temperature of LED lamp 22. Once the temperature is abnormal, it can provide timely feedback, allowing staff to take timely measures to avoid affecting the lifespan and lighting performance of LED lamp 22 due to excessive temperature, thus improving the ability to ensure the stable operation of LED lamp 22.

[0044] Next, the shielding assembly is installed according to the position of the LED light 22 and the mounting plate 11. After the shielding assembly is installed, the annular mounting bracket 24 is installed below the LED light 22 to provide support for the light-transmitting component. The light-transmitting component consists of a high-transmittance electromagnetic shielding film 25 and an annular support bracket 26. With the assistance of the second mounting groove on the annular support bracket 26 and the annular mounting bracket 24, as well as the magnetic pad 27, the high-transmittance electromagnetic shielding film 25 is installed between the two. The magnetic pad 27 simplifies the installation process, makes the assembly of the light-transmitting component more convenient, and improves the ease of installation. The cooperation between the high-transmittance electromagnetic shielding film 25 and the annular support bracket 26 can not only ensure good light transmission, ensuring that the light of the LED light 22 can pass through to meet the underground lighting needs, but also shield electromagnetic interference, meeting the dual needs of underground LED work light lighting and anti-electromagnetic interference.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
