A server anti-static device

Abstract

This utility model discloses a server anti-static device, including a mounting box with mounting plates on both sides. The mounting plates are connected to the server chassis by bolts. An anti-static mechanism is provided inside the mounting box, including a mounting slot inside the mounting box, a fan installed inside the mounting slot, and an ion generating module located below the fan. The ion generating module is located inside the mounting box, and a triggering mechanism is located below the mounting box. By setting up the anti-static mechanism, under the control of the PLC controller, when the blade is inserted or removed, the ion generator generates ions, and the fan blows the ion airflow towards the slot opening area, forming a stable air curtain barrier. This air curtain can not only neutralize the static charge entering the slot opening, but also effectively block external charged particles from entering the server, thereby achieving all-round protection for sensitive electronic components.

Description

Technical Field

[0001] This utility model relates to the field of blade server technology, and more specifically, to a server anti-static device. Background Technology

[0002] With the rapid development of information technology, servers, as the core equipment of data centers, are of paramount importance in terms of stability and reliability. Electrostatic discharge (ESD) is a significant issue during server operation, especially in high-density, high-performance blade servers. Static electricity can not only cause data transmission errors and hardware damage, but may even trigger system crashes, severely impacting business continuity.

[0003] Traditional anti-static measures mainly include using anti-static flooring and grounding devices, which can reduce the accumulation and release of static electricity to some extent. However, in scenarios where servers frequently undergo hot-swapping operations—which involve inserting and removing server blades without interrupting power—while this improves system flexibility and maintainability, it also increases the risk of electrostatic discharge. During the insertion and removal process, static electricity from the external environment can easily penetrate into the server chassis, especially when operators touch the blades and slots; static electricity may be conducted into the server through the human body. Furthermore, friction and contact between the blades and slots also generate static electricity. If this static electricity is not released in time, it may discharge momentarily, damaging the server hardware. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a server anti-static device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] An anti-static device for servers includes a mounting box with mounting plates on both sides. The mounting plates are connected to the server chassis by bolts. An anti-static mechanism is provided inside the mounting box. The anti-static mechanism includes a mounting slot inside the mounting box, a fan installed inside the mounting slot, an ion generating module below the fan, and a triggering mechanism below the mounting box.

[0007] Furthermore, the ion generation module includes an ion generator and a discharge needle, with the discharge needle located at the bottom of the ion generator.

[0008] Furthermore, in order to enable the anti-static mechanism to be activated when inserting or removing the blade server, the triggering mechanism includes a fixing plate located below the mounting box. The fixing plate is connected to the mounting box, and an elastic sheet is connected to the outside of the fixing plate. An abutment block is provided on one side of the elastic sheet. A fixing groove is provided inside the fixing plate, and a pressure sensor is connected inside the fixing groove. The pressure sensor is electrically connected to the PLC controller, and the PLC controller is electrically connected to the fan and the ion generator.

[0009] Furthermore, the PLC controller is located inside the mounting box, which is connected to a partition. The PLC controller is located on one side of the partition, and the fan is located on the other side of the partition.

[0010] Furthermore, in order to direct the ion flow towards the slot opening, an exhaust duct is provided at the bottom of the mounting box. Additionally, a dust filter is provided at the top of the fan, and the dust filter is connected to the mounting box by bolts.

[0011] Furthermore, the server chassis has slots with blades inserted inside.

[0012] Furthermore, the mounting box is located above the slot opening.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting up an anti-static mechanism, under the control of the PLC controller, when the blade is inserted or removed, the ion generator generates ions and blows the ion airflow to the slot opening area with the help of a fan, forming a stable air curtain barrier. This air curtain can not only neutralize the static charge entering the slot opening, but also effectively block external charged particles from entering the server, thereby achieving all-round protection for sensitive electronic components.

[0015] (2) By setting a trigger mechanism, intelligent response to hot-swapping operations is achieved. When a technician inserts or removes the blade, the blade will apply pressure to the contact block or the pressure will fail, thereby changing the value of the pressure sensor. The sensor transmits the signal to the PLC controller, which automatically starts the fan and ion generator to form an active anti-static protection mechanism, which can effectively prevent electrostatic discharge from damaging the server hardware and ensure the stability and reliability of the server.

[0023] 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.

[0024] like Figures 1-4As shown, the server anti-static device according to an embodiment of this utility model includes a mounting box 1. The mounting box 1 is the basic structure of the entire anti-static device, providing space for the installation and protection of other components. Mounting plates 2 are provided on both sides of the mounting box 1. The mounting plates 2 are connected to the server chassis 11 by bolts. The mounting plates 2 are mainly used to fix the mounting box 1 to the server chassis 11. The server chassis 11 is provided with a slot 9 for inserting a blade 10 (i.e., a blade server). The blade 10 is inserted into the slot 9. The blade 10 is a highly integrated computing unit used in high-density data center environments. The mounting box 1 is located above the slot 9. An anti-static mechanism 3 is provided inside the mounting box 1. The anti-static mechanism 3 includes a mounting groove 301 located inside the mounting box 1. A fan 302 is installed inside the mounting groove 301. The function of the fan 302 is to generate airflow to help the ions generated by the ion generation module 4 to be more evenly distributed to the target area. Below the fan 302 is an ion generating module 4, which is located inside the mounting box 1. The ion generating module 4 includes an ion generator 401 and a discharge needle 402. The ion generator 401 is responsible for generating positive and negative ions, which can neutralize the static charge in the air. The discharge needle 402 is located at the bottom of the ion generator 401. The discharge needle 402 enhances the efficiency of ion generation through the tip discharge effect. The bottom of the mounting box 1 is provided with an exhaust duct 7 to optimize the airflow path, so that the ion wind driven by the fan 302 and processed by the ion generating module 4 can effectively cover the slot opening 9 area, forming an effective protective barrier. The top of the fan 302 is provided with a dustproof net 8, which is connected to the mounting box 1 by bolts. The dustproof net 8 can effectively block external dust from entering the device, preventing dust accumulation from affecting the normal operation of the fan 302 and the ion generating module 4, thereby extending the service life of the equipment and maintaining good working condition.

[0025] like Figures 1-4As shown, a triggering mechanism 5 is located below the mounting box 1. The triggering mechanism 5 includes a fixing plate 501 located below the mounting box 1. Its main function is to provide a stable mounting base for the triggering mechanism 5, ensuring that the entire triggering mechanism can be firmly attached to the mounting box 1, thereby guaranteeing the accuracy of the triggering action. The fixing plate 501 is connected to the mounting box 1, and an elastic sheet 502 is connected to the outside of the fixing plate 501. It has a certain elasticity and restoring force. When subjected to external pressure (such as when the blade 10 is inserted or pulled out), the elastic sheet 502 will deform and then quickly return to its original shape. This characteristic allows the elastic sheet 502 to quickly reset after triggering, ready for the next trigger. An abutment block 503 is provided on one side of the elastic sheet 502, and a fixing groove 504 is provided inside the fixing plate 501. A pressure sensor 505 is connected inside the fixing groove 504, which is responsible for detecting the pressure changes transmitted by the abutment block 503. Once a specific pressure value is detected, the sensor sends a signal to the PLC controller 506, initiating the operation of the fan 302 and ion generator 401, thus achieving effective protection against static electricity. The pressure sensor 505 is electrically connected to the PLC controller 506, which in turn is electrically connected to the fan 302 and ion generator 401. The PLC controller 506 is equipped with a timing module and serves as the control center of the entire system. It receives signals from the pressure sensor 505 and controls the operation of the fan 302 and ion generator 401 accordingly. The PLC controller 506 is located inside the mounting box 1, which is connected to a partition 6. The PLC controller 506 is located on one side of the partition 6, and the fan 302 is located on the other side. The partition 6 separates the PLC controller 506 from the fan 302. This layout not only helps reduce the mutual interference between the electrical components and the airflow components but also improves the overall safety of the system.

[0026] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0027] In actual use, when technicians need to remove and reinstall the blades 10 inside the server chassis 11, the elastic sheet 502 on the outside of the server chassis 11 is in a state of no pressure. When the blade 10 is pulled out, the blade 10 compresses the elastic sheet 502 during its movement, causing the elastic sheet 502 to deform. This causes the abutment block 503 to come into contact with the pressure sensor 505, changing the state of the pressure sensor 505 from a pressureless state to a pressurized state. It sends a signal to the PLC controller 506. After receiving the signal, the PLC controller 506 responds quickly and starts the fan 302 and ion generator 401 inside the mounting box 1. The fan 302 starts running, generating a stable airflow that drives the positive and negative ions generated by the ion generation module 4 to flow downwards. These ions are released more efficiently through the discharge needle 402 and diffused evenly into the air under the action of the electric field. They are then pushed by the fan 302 through the exhaust duct 7 and precisely blown towards the slot opening 9 area below, forming a continuous ion air curtain. This ion curtain effectively neutralizes static charges in the air, preventing static electricity from entering the slot 9. When the blade 10 is fully pulled out, the pressure sensor 505 changes from a pressurized state to a depressurized state. The pressure sensor 505 feeds this change back to the PLC controller 506, indicating that the pull-out action is complete. If a new blade 10 is inserted at this time, the elastic sheet 502 will be compressed again, causing the pressure sensor 505 to undergo a change from a depressurized state to a pressurized state and back to a depressurized state. By analyzing this pressure change curve, the PLC controller 506 can accurately identify that an insertion operation is currently in progress. Based on this judgment, after the blade 10 insertion action is completed, the PLC controller 506 will continue to keep the fan 302 and the ion generation module 4 running for a period of time, such as 30 seconds to several minutes, to ensure that the electrostatic environment in the slot 9 area is completely stable and to completely eliminate electrostatic interference introduced by the operation. Subsequently, the PLC controller 506 can gradually reduce the fan 302 speed and ion generation intensity according to a preset program until the device is automatically shut down, thereby achieving energy saving and consumption reduction while ensuring the protective effect. If only the blade 10 is being removed, the PLC controller 506 sets a time limit through the timing module. If no blade 10 is inserted within the specified time, the PLC controller 506 will not immediately shut down the anti-static mechanism 3. Instead, it will start a preset delay shutdown program to keep the fan 302 and the ion generating module 4 running for 10 to 30 seconds to ensure that the static electricity that may be introduced during the removal process is fully neutralized. If only the insertion operation is being performed, the anti-static function will be activated immediately after the pressure sensor 505 senses the pressure and will continue to run for a set time before shutting down the device.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
